The production process of solar cells involves various processes, and the cells need to be placed in a specific boat when they are handled by a specific process. For example, during laser etching, the battery plate is arranged in a special boat; during boron expansion, the cell is placed in another special boat. Therefore, in the process of producing solar cells, it is necessary to transfer the cells in one boat into another.

Currently, battery transfer loading apparatuses have emerged that transfer battery cells in one container (one of the boat and basket) to another container (the other of the boat and basket). These battery sheet transfer loading devices typically transfer and load battery sheets from one container into another container by: the method comprises the steps of turning a first container from a vertical state to a horizontal state, lifting a first top piece to penetrate the first container so as to jack up battery pieces in the first container, grabbing the jacked battery pieces by a sucker unit comprising a plurality of suckers, horizontally moving the sucker unit to the position right above a second container, lifting a second top piece to penetrate the second container in the horizontal state, loosening the battery pieces by the sucker unit so as to put the battery pieces into the second top piece, and lowering the second top piece so as to put the battery pieces into the second container. In this process, the battery sheet is transferred from the first container to the first top sheet member, then from the first top sheet member to the suction cup unit, then from the suction cup unit to the second top sheet member, and then from the second top sheet member to the second container. However, the battery piece may move relative to the suction cup in the process of following the horizontal movement of the suction cup, so that the battery piece is greatly shifted, which reduces the positioning accuracy of the battery piece and is not beneficial to accurately placing the battery piece into the second container.

Referring to fig. 1, a first boat 400 is a boat for loading battery cells during the process of treating the battery cells with the former process, and a second boat 500 is a boat for loading battery cells during the process of treating the battery cells with the latter process. After the battery cells have been processed with the former process, and before the battery cells have been processed with the latter process, the battery cells in the first boat 400 need to be transferred into the second boat 500.

Referring to fig. 1 and 2, the present invention first provides a battery sheet transferring and loading apparatus 100 for transferring battery sheets in a first boat 400 into a second boat 500. The battery piece transferring and loading device 100 comprises a frame 1, a sucker unit 2, a switching table 4, two boat clamping devices 3 and a top piece 5. The sucker unit 2 is located right above the frame 1 in a lifting manner, and a space between the frame 1 and the sucker unit 2 is a loading and unloading space. The switching table 4 is movably provided to the frame 1. The two boat clamping devices 3 are used to clamp the first boat 400 and the second boat 500, respectively. The two boat clamping devices 3 are rotatably arranged on the switching table 4, and the switching table 4 moves the two boat clamping devices 3 to the loading and unloading space. The top sheet member 5 is liftably located right under the suction cup unit 2, and acts on the battery sheet to eject the battery sheet out of the first boat 400 or put into the second boat 500. The suction cup unit 2 can suck the battery sheet lifted by the top sheet member 5.

One process of transferring the battery cells in the first boat 400 into the second boat 500 by the battery cell transfer loading apparatus 100 is as follows: the top piece 5 is positioned right below the loading and unloading space, and the first boat 400 loaded with the battery pieces is clamped in a boat clamping device 3; the boat clamping device 3 clamping the first boat 400 is turned over so that the first boat 400 is in a horizontal state and the first boat 400 is located in the loading/unloading space. Then, the top sheet member 5 is lifted to jack up the battery cells in the first boat 400 while clamping the empty second boat 500 in the other boat clamping device 3 and turning over the boat clamping device 3 clamping the second boat 500 so that the second boat 500 is in a horizontal state. After that, the suction cup unit 2 is caused to suck the battery sheet lifted by the top sheet member 5. Then, the top sheet 5 is lowered to the position right below the loading and unloading space; the switching stage 4 is moved so that the first boat 400 is moved out of the loading space and the second boat 500 is moved into the loading space. Thereafter, the top sheet member 5 is lifted up so that the top sheet member 5 holds the battery sheet; the suction cup unit 2 is caused to release the battery sheet to put the battery sheet into the top sheet member 5. The top sheet member 5 is then lowered to place the battery cells into the second boat 500. Through using this battery piece to transport loading equipment 100 to shift the battery piece in the first boat 400 to in the second boat 500, avoided the battery piece to follow sucking disc 21 horizontal migration, be favorable to preventing that the battery piece from taking place great positional deviation, can improve the location accuracy of battery piece to in being convenient for shift the battery piece to the second boat 500.

Moreover, in the conventional battery piece transferring and loading device, in order to ensure that the battery piece can move horizontally along with the suction cup, the suction cup needs to apply a large suction force to the battery piece, and in order to prevent the battery piece from being greatly shifted in the process of moving horizontally along with the suction cup, the suction cup is generally moved horizontally slowly at a low speed, which reduces the efficiency of transferring the battery piece. The battery piece transferring and loading device 100 provided by the invention can improve the efficiency of transferring the battery pieces because the battery pieces are prevented from moving horizontally along with the sucker 21, and the sucker unit 2 does not need to apply larger force to the battery pieces, thereby being beneficial to reducing the use cost.

In addition, compared with the battery piece transferring and loading device 100 in the prior art, the battery piece transferring and loading device 100 provided by the invention only needs to be provided with one top piece 5, so that the structure of the battery piece transferring and loading device 100 can be simplified, and the use cost can be reduced. Moreover, when installing conventional battery sheet transfer loading apparatus, it is necessary to align the first top sheet member with the first container and the second top sheet member with the second container, and alignment needs to be performed twice, which results in complicated installation on the one hand, more structures to be aligned on the other hand, increased risk of alignment failure, and poor stability and reliability of the apparatus as a whole. When the battery piece transferring and loading device 100 provided by the invention is installed, the top piece 5 is only required to be aligned with the sucker unit 2, only one time alignment is required, the installation is convenient, and the stability and the reliability of the whole device are relatively high.

It will be appreciated that a plurality of gaps are provided in the first boat 400 and the second boat 500 at equal intervals, each gap accommodating one cell, so that the respective cells are equally spaced. Typically, the first boat 400 and the second boat 500 are identical in shape and size.

Referring to fig. 2 and 3, the top sheet member 5 includes a top sheet portion 51 and a plurality of rows of second partition members 52 fixed to the top side of the top sheet portion 51, the plurality of rows of second partition members 52 being parallel to each other. The plurality of second spacers 52 in each row of the second spacers 52 are equally spaced apart in the horizontal direction, and a third gap 53 is formed between two adjacent second spacers 52 in each row of the second spacers 52, wherein the third gaps 53 in one row of the second spacers 52 are disposed in one-to-one correspondence with the third gaps 53 in the other row of the second spacers 52 and form a space for accommodating one battery cell. When the top sheet 5 is lifted, the second separator 52 is offset from the battery sheets, and as the top sheet 5 is lifted, each battery sheet is lifted by the top sheet 51 by contacting the top sheet 51 and gradually lifted by the corresponding third gap 53.

Illustratively, the frame 1 includes a first sliding rail disposed vertically, and the top piece 5 includes a first sliding table adapted to the first sliding rail, and the first sliding rail is slidably matched with the first sliding table, so that the top piece 5 is disposed on the frame 1 in a liftable manner. Preferably, the first sliding rail and the first sliding table participate in forming a linear module.

In other embodiments, the top piece 5 may also be arranged at a distance from the frame 1. For example, the battery piece transferring and loading system further comprises a lifting mechanism, wherein a base body of the lifting mechanism and the frame 1 are fixed on the ground at intervals, and the top piece 5 is fixedly arranged on the lifting structure of the lifting mechanism. The lifting mechanism may be a lifting mechanism existing in the prior art, and will not be described herein.

Referring to fig. 2 and 4, the suction cup unit 2 includes a plurality of suction cups 21 equally spaced apart in a horizontal direction, and a fourth gap 211 accommodating one battery sheet is formed between two adjacent suction cups 21. When the battery pieces enter the sucker unit 2, the battery pieces are staggered with the sucker 21, and each battery piece can enter the corresponding fourth gap 211.

Referring to fig. 1, a suction cup unit 2 is spaced apart from a frame 1. In other embodiments, the suction cup unit 2 may also be directly fixed to the frame 1.

Referring to fig. 1, a switching table 4 is slidably connected to a frame 1, and two boat clamping devices 3 are sequentially disposed along a sliding direction of the switching table 4. Thus, by sliding the switching table 4, the boat 3 can be moved into and out of the loading/unloading space.

Illustratively, referring to fig. 1, the rack 1 includes a second slide rail 11, and the switching table 4 includes a second slide table 41 adapted to the second slide rail 11, and the second slide rail 11 forms a sliding fit with the second slide table 41, so that the switching table 4 is slidably connected to the rack 1. Preferably, the second sliding rail 11 and the second sliding table 41 participate in forming a linear module. Further, the frame 1 further includes a sub slide rail 12 parallel to the second slide rail 11, the switching table 4 further includes a sub slide table adapted to the sub slide rail 12, and the switching table 4 is mounted on the second slide rail 11 and the sub slide rail 12, which is advantageous in that the switching table 4 slides smoothly.

In other embodiments, the switching table 4 is rotatably connected to the frame 1, and the two boat clamping devices 3 are sequentially arranged along a first circumference, and the center of the first circumference is located on the rotating shaft of the switching table 4. Thus, by rotating the switching table 4, the boat 3 can be moved into and out of the loading/unloading space.

The portion of the switching table 4 located directly below the suction cup unit 2 is provided separately in the escape hole through which the top sheet member 5 passes.

During the jacking of the battery cells by the top piece 5, small positional deviations of the battery cells may occur, which do not normally lead to the battery cells not being able to move into the second boat 500. However, in order to easily put the battery cells into the second boat 500 and prevent the battery cells from being damaged during the process of putting the battery cells into the second boat 500, it is conceivable to provide the centering mechanism 6 to center the positions of the battery cells so that the same sides of all the battery cells are aligned. Referring to fig. 2, the battery piece transferring and loading apparatus 100 further includes a righting mechanism 6, and the righting mechanism 6 is located in the loading and unloading space. The return mechanism 6 includes two return pieces 61 disposed opposite to each other, and the two return pieces 61 can be brought close to or away from each other in the horizontal direction. In this way, the two correcting members 61 can be moved in opposite directions, so that the two correcting members 61 are respectively abutted against two sides of all the battery pieces, the same sides of all the battery pieces are aligned, and the correction of the positions of the battery pieces is realized, so that the battery pieces can be conveniently moved into the sucker unit 2, and the battery pieces are prevented from being damaged in the process of being put into the sucker unit 2.

Referring to fig. 6, the righting mechanism 6 includes two first driving assemblies 64, each first driving assembly 64 includes a first power output 642, and the first power output 642 is connected to the frame 1 and is movable in a horizontal direction. The correcting members 61 are disposed in one-to-one correspondence with the first driving assemblies 64, and each correcting member 61 is fixedly disposed on the corresponding first power output member 642. In this way, the return member 61 can be driven to horizontally move by the horizontal movement of the first power output member 642 to achieve return. Further, by changing the preset displacement of the first power output 642, the righting mechanism 6 can be adapted to the righting of the battery pieces of different specifications.

In some embodiments, the normalization 61 is threaded/snapped/welded to the first power take-off 642.

Referring to fig. 2 and 6, the righting mechanism 6 further includes two mounting assemblies 65, each mounting assembly 65 includes a mounting seat 651, and a plurality of mounting positions 6511 are disposed on the mounting seat 651, and the plurality of mounting positions 6511 are sequentially distributed along the moving direction of the first power output member 642. The return member 61, the mounting assembly 65 and the first driving assembly 64 are arranged in one-to-one correspondence. Each mounting seat 651 is fixedly arranged on the corresponding first power output element 642, and each correcting element 61 is detachably locked on one mounting position 6511 on the corresponding mounting seat 651. The two correcting members 61 are moved closer to or farther from each other in the horizontal direction by the corresponding first power output members 642. In this way, the rectifying member 61 can be mounted at different mounting positions 6511, so that the initial position of the rectifying member 61 and the initial spacing between the two rectifying members 61 can be adjusted, so that the rectifying mechanism 6 is suitable for rectifying the battery pieces of different specifications. The initial position refers to a position of the return member 61 when the first power output member 642 corresponding to the first driving assembly 64 is returned, and the initial interval refers to an interval between the two return members 61 when both the first power output members 642 are returned.

It should be noted that, the two means of mounting the rectifying member 61 at different mounting positions 6511 and changing the preset displacement of the first power output member 642 can make the rectifying mechanism 6 suitable for rectifying the battery pieces of different specifications, and the combination of the two means can make the rectifying mechanism 6 suitable for rectifying the battery pieces of more specifications.

Illustratively, the normalization 61 is threaded/snapped into the mounting location 6511.

Referring to fig. 6, in order to achieve the horizontal movement of the first power output member 642, the first driving assembly 64 includes a first housing 641, the first housing 641 is fixedly disposed on the frame 1, and the first power output member 642 is slidably connected to the first housing 641 along the horizontal direction. In other embodiments, the first power output member 642 may directly form a sliding pair with the frame 1, and the sliding direction of the first power output member 642 is along the horizontal direction.

In some embodiments, first drive assembly 64 is a cylinder, first housing 641 is a block of the cylinder, and first power take-off 642 is a piston rod of the cylinder. In other embodiments, the first driving component 64 is a linear module, the first base 641 is a sliding rail of the linear module, and the first power output member 642 is a sliding table of the linear module.

Referring to fig. 6, each mounting assembly 65 further includes a threaded connection 652, and each of the normalization members 61 is locked to one of the mounting locations 6511 on the corresponding mounting seat 651 by the threaded connection 652.

Illustratively, the threaded connection 652 is a bolt or screw.

Referring to fig. 6, each mounting location 6511 is provided with a mounting hole 65111, and a threaded connection 652 is provided through the mounting hole 65111 and locks the alignment member 61 to the mounting location 6511; in the vertical direction, the threaded connection 652 is slidable along the mounting hole 65111. In this way, the correcting member 61 can be moved along the vertical direction in the unlocked state of the threaded connecting member 652, and then the correcting member 61 is locked on the mounting position 6511 by the threaded connecting member 652, so that the height position of the correcting member 61 can be adjusted to adapt to the correction of the battery cells with different specifications.

Preferably, in the horizontal direction, the threaded connection 652 abuts the bore wall of the mounting bore 65111. This can prevent the positional displacement of the return member 61 in the horizontal direction, thereby ensuring that the return member 61 can abut against the battery piece without changing the preset displacement of the first power output member 642 and without causing excessive pressure to the battery piece to cause damage to the battery piece.

Preferably, referring to fig. 6, each mounting location 6511 is provided with a plurality of mounting holes 65111, and each mounting assembly 65 includes a plurality of threaded connections 652, and each mounting hole 65111 corresponds to at least one threaded connection 652, i.e., at least one threaded connection 652 passes through one mounting hole 65111. This can prevent the distance between the two return pieces 61 from being changed due to the rotation of the return pieces 61, thereby ensuring that the return pieces 61 can abut against the battery pieces without changing the preset displacement of the first power output piece 642 and without causing excessive pressure to the battery pieces to damage the battery pieces.

Preferably, each mounting hole 65111 corresponds to at least two threaded connections 652, i.e., at least two threaded connections 652 each pass through the same mounting hole 65111. This facilitates a secure locking of the normalization element 61 to the mounting location 6511.

In other embodiments, only mounting holes 65111 may be provided on each mounting location 6511, but one mounting hole 65111 corresponds to multiple threaded connections 652, i.e., multiple threaded connections 652 pass through the same mounting hole 65111 and lock the alignment member 61 to the mounting location 6511 at the same time. This also prevents the return member 61 from rotating, which would result in a change in the distance between the two return members 61.

Preferably, referring to fig. 6, the mounting seat 651 is provided with a groove 6512, and a bottom wall of the groove 6512 forms a mounting location 6511. The recess 6512 has two opposing side walls, a first retaining wall 65121 and a second retaining wall, respectively. The first limiting wall 65121 and the second limiting wall are both planar and perpendicular to the sliding direction of the first power output element 642. The mounting assembly 65 further includes a connecting post 653, where two sides of the connecting post 653 are planar and respectively abut against the first limiting wall 65121 and the second limiting wall. The restoring member 61 is fixedly arranged on the connecting post 653, and the threaded connecting member 652 is arranged on the mounting position 6511 in a penetrating manner and is in threaded connection with the connecting post 653. Thus, tightening the threaded connection 652 locks the connection post 653 on the mounting location 6511, thereby locking the rectifying member 61 on the mounting location 6511, and the abutting relationship among the connection post 653, the first limiting wall 65121 and the second limiting wall can prevent the rectifying member 61 from being shifted in the horizontal direction, thereby ensuring that the rectifying member 61 can abut against the battery plate without changing the preset displacement of the first power output member 642 and without causing excessive pressure to the battery plate to damage the battery plate.

Referring to fig. 5, opposite sides of the two correcting members 61 are clamping sides 611, the clamping sides 611 are planar, and the clamping sides 611 of the two correcting members 61 are parallel. A plurality of first separating pieces 62 are fixed on each clamping side 611 at equal intervals along the horizontal direction, a first gap 621 is formed between the adjacent first separating pieces 62 on each correcting piece 61, and the first gap 621 on one correcting piece 61 and the first gap 621 on the other correcting piece 61 are arranged in a one-to-one correspondence manner and form a space for accommodating one battery piece. In this way, during the process of resetting the cell position by the resetting mechanism 6, each cell enters the corresponding first gap 621, respectively, and the two first separators 62 forming the first gap 621 can function to restrict the cell position. In this way, the clamping side 611 and the adjacent two first separators 62 thereon respectively straighten one battery piece from three sides thereof, which is advantageous in improving the straightening effect of the straightening mechanism 6.

Referring to fig. 5, the sidewalls of the first spacers 62 are curved, and the distance between two adjacent first spacers 62 is reduced and then increased along the direction perpendicular to the clamping side 611. In this way, the battery piece is in point contact or line contact with the first separator 62, and the contact area between the battery piece and the first separator 62 is small, so that the battery piece and the first separator 62 are prevented from being damaged due to large friction.

Referring to fig. 5, a guide tooth 63 is fixed on a side of each first partition 62 away from the clamping side 611, and a second gap 631 exists between two adjacent guide teeth 63 on the same correcting member 61, and the second gap 631 gradually widens in a direction gradually approaching the other correcting member 61. Thus, even if the battery piece is shifted to a certain position, the battery piece can smoothly enter the first gap 621 through the second gap 631 under the guidance of the guide tooth 63, which is beneficial for the righting mechanism 6 to smoothly righting the position of the battery piece.

Preferably, the gap between two adjacent guide teeth 63 on the same correcting member 61 is splayed.

Referring to fig. 5, the side wall of the guiding teeth 63 is in a truncated cone shape or a conical shape. In this way, even if the battery piece is in contact with the guide teeth 63 due to a certain position deviation, the battery piece is in point contact with the guide teeth 63, the contact area between the battery piece and the guide teeth 63 is small, and the battery piece and the guide teeth 63 are prevented from being damaged due to large friction.

Preferably, referring to fig. 1, in some embodiments, the suction cup unit 2 is arranged to be liftable. The process of transferring the battery cells from the first boat 400 to the suction cup unit 2 is as follows: the top piece 5 pushes the battery piece to the height position of the righting mechanism 6 and then stops; then, the two correcting members 61 of the correcting mechanism 6 are close to each other to correct the position of the battery piece, and after the correction of the position of the battery piece is completed, the two correcting members 61 are far away from each other; after that, the suction cup unit 2 descends to gradually approach the battery pieces, and after each battery piece jacked up by the top piece 5 is located in the corresponding fourth gap 211, each suction cup of the suction cup unit 2 sucks the corresponding battery piece. The process of transferring the battery cells from the suction cup unit 2 to the second boat 500 is as follows: the sucker unit 2 is fixed, the top piece 5 rises to gradually approach the battery pieces, and after each battery piece absorbed by the sucker unit 2 is positioned in the corresponding third gap 53, each sucker of the sucker unit 2 loosens the corresponding battery piece; then, the two correcting members 61 of the correcting mechanism 6 are close to each other to correct the position of the battery piece, and after the correction of the position of the battery piece is completed, the two correcting members 61 are far away from each other; the top sheet member 5 is then slowly and stably lowered so that the battery cells enter the second boat 500.

Illustratively, referring to fig. 1, the battery piece transporting and loading apparatus 100 further includes a robotic arm 8, the robotic arm 8 having a translational joint, the translational joint having a movement direction along a vertical direction. The sucker unit 2 is fixedly arranged at the tail end of the mechanical arm 8, and the translational joint of the mechanical arm 8 drives the sucker unit 2 to lift when moving up and down. The base of the mechanical arm 8 can be fixedly arranged on the ground or directly fixedly arranged on the frame 1.

In other embodiments, the suction cup unit 2 is fixedly arranged. As the battery pieces are transferred from the first boat 400 to the suction cup unit 2, the top sheet member 5 is continuously lifted to directly push the battery pieces into the suction cup unit 2. In these embodiments, in order to prevent a large positional deviation of the battery sheet, the top sheet member 5 is slowly and stably raised at a very low speed, and the width of the third gap is only slightly larger than the thickness of the battery sheet, and the width of the third gap is, for example, 0.05mm larger than the thickness of the battery sheet. In these embodiments, when transferring the battery pieces from the suction cup unit 2 to the second boat 500, the top sheet member 5 is lifted to gradually approach the battery pieces, and after each battery piece sucked by the suction cup unit 2 is located in the corresponding third gap 53, each suction cup of the suction cup unit 2 releases the corresponding battery piece; the top sheet member 5 is then lowered so that the battery cells enter the second boat 500. In these embodiments, the centering mechanism 6 may be provided, and the position of the battery piece may be centered by the centering mechanism 6 before the battery piece is pushed into the suction cup unit 2 and before the battery piece is brought into the second boat 500.

The boat is held by the boat holding table 311 with two boat holding members 3121 located above the boat holding table 311 on the top side of the boat holding table 311 and by moving the boat holding members 3121 toward each other.

Referring to fig. 10 and 11, the boat structure 312 further includes a second driving assembly 313, the second driving assembly 313 includes a second power output member 3132, the second power output member 3132 is slidably disposed at the bottom side of the boat table 311 in the horizontal direction, and the boat 3121 is connected to the second power output member 3132 and is capable of moving in the thickness direction of the boat table 311. The second drive assemblies 313 are also provided in two and one-to-one correspondence with the boat clamps 3121. Thus, by moving the two boat members 3121 simultaneously in the thickness direction of the boat table 311, the positions of the two boat members 3121 can be changed, thereby adjusting the holding positions. According to the thickness of the boat base, the two boat clamping pieces 3121 are synchronously moved to the optimal clamping position or the vicinity of the optimal clamping position along the thickness direction of the boat bearing platform 311, and then the two boat clamping pieces 3121 are driven to move towards each other by the two second driving components 313 until the two boat clamping pieces 3121 are abutted against the two sides of the boat base, so that the boat can be stably clamped.

Referring to fig. 10 and 11, the second driving assembly 313 further includes a second seat 3131, the second seat 3131 is fixedly disposed at the bottom side of the boat deck 311, the second power output member 3132 is slidably connected to the second seat 3131, and the second power output member 3132 slides along a horizontal direction relative to the second seat 3131. Thus, sliding the second power take-off 3132 relative to the second housing 3131 can move the boat 3121 horizontally. In other embodiments, the second power take-off 3132 may also directly form a sliding pair with the boat table 311, where the sliding direction of the sliding pair is along the horizontal direction, and in these embodiments, the boat table 311 functions as both a boat carrier and a second seat 3131.

In some embodiments, the second drive assembly 313 is a cylinder, the second housing 3131 is a block of the cylinder, and the second power output 3132 is a piston rod of the cylinder.

The boat-clamping member 3121 is fixedly disposed on the third power output member, and the third driving assembly 314 has two boat-clamping members 3121 and is disposed in one-to-one correspondence. Thus, the third power take-off member is lifted and lowered to move the boat 3121 in the thickness direction of the boat table 311, thereby adjusting the position of the boat 3121.

Referring to fig. 9 to 11, the third driving assembly 314 further includes a third housing 3141, the third housing 3141 is fixedly disposed on the second power output member 3132, the third power output member is slidably connected to the third housing 3141, and the third power output member slides along the thickness direction of the boat deck 311 relative to the third housing 3141. Thus, sliding the third power take-off relative to the third housing 3141 moves the boat 3121 in the thickness direction of the boat table 311, thereby adjusting the position of the boat 3121.

In some embodiments, the third drive assembly 314 is a cylinder, the third housing 3141 is a block of the cylinder, and the third power output is a piston rod of the cylinder. In other embodiments, the third driving component 314 is a linear module, the third seat 3141 is a sliding rail of the linear module, and the third power output is a sliding table of the linear module.

In other embodiments, the boat 3121 may also directly form a sliding pair with the second power take-off 3132, the sliding direction of the sliding pair being along the thickness direction of the boat table 311, which also enables the boat 3121 to move along the thickness direction of the boat table 311.

In other embodiments, the positions of the second driving assembly 313 and the third driving assembly 314 may be interchanged, specifically, the third seat 3141 is fixedly arranged on the boat table 311, the third power output member is slidably connected to the third seat 3141, the second seat 3131 is fixedly arranged on the third power output member, the second power output member 3132 is slidably connected to the second seat 3131, and the boat clamping member 3121 is fixedly arranged on the second power output member 3132.

The connecting members 315 are provided in two and are disposed in one-to-one correspondence with the second power output members 3132. Preferably, the connection member 315 is a plate-like body.

Referring to fig. 11, the second driving assembly 313 further includes a guiding structure 3133, the guiding structure 3133 includes a guiding sleeve 31332 and a guiding member 31331, and the guiding sleeve 31332 is fixedly disposed on the bottom side of the boat table 311 and provided with a guiding hole adapted to the guiding member 31331. The guide member 31331 is fixedly disposed on the third seat 3141, penetrates through the guide hole, and is parallel to the second power output member 3132. In this way, the mating relationship between the guide member 31331 and the guide hole functions as a guide, enabling the second power output member 3132 to be guided and restrained at the time of horizontal movement, to ensure the accuracy and stability of the horizontal movement of the second power output member 3132.

Referring to fig. 11, the guide 31331 is a cylinder, and the guide hole is a circular hole. In other embodiments, the guide member 31331 may be a cylindrical body with other shapes, and the guide hole may be a hole with other shapes, for example, the guide member 31331 may be a triangular prism or a square column, and accordingly, the guide hole may be a triangular hole or a square hole.

Preferably, the first driving member includes two guide structures 3133, and the two guide structures 3133 are located at both sides of the second power output member 3132, respectively. This is advantageous in enhancing the guiding function and in improving the accuracy and stability of the horizontal movement of second power output member 3132.

More preferably, the two guide structures 3133 are symmetrically disposed about the second power output member 3132. This is advantageous in enhancing the guiding function and in improving the accuracy and stability of the horizontal movement of second power output member 3132.

Referring to fig. 7 to 11, the boat-clamping device 3 further includes a blade-supporting structure 32, and the blade-supporting structure 32 is used for supporting the battery blades in the boat during the overturning process of the boat-clamping device 3.

Referring to fig. 7-11, the blade structure 32 is provided on the same side of the two boat clamps 3121. Thus, when the boat clamping device 3 is turned in a specific direction (clockwise in fig. 7), the blade supporting structure 32 is located below the boat clamped by the boat clamping mechanism 31, so as to support the battery blades in the boat and prevent the battery blades from falling from the boat.

Referring to fig. 7-11, the blade structure 32 includes two blade members 321, the two blade members 321 being disposed opposite each other and rotatably coupled to the two boat-clamping members 3121, respectively. In this way, the space between the two support pieces 321 can be penetrated by the top piece 5, and the two support pieces 321 are rotated to be in contact with the battery pieces in the boat clamped by the two boat clamping pieces 3121, so as to play a role in supporting the battery pieces in the boat. Before the boat is clamped in the boat clamping device 3 or before the boat is taken out of the boat clamping device 3, the two supporting pieces 321 can be rotated away from each other to a position where the two supporting pieces do not contact the battery pieces, so that the battery pieces are prevented from being damaged due to friction between the supporting pieces 321 and the battery pieces.

Referring to fig. 7 and 8, the blade 321 includes a first rotational axis 3212, the first rotational axis 3212 being rotatably coupled to the boat 3121. The blade structure 32 further includes a fourth drive assembly 322, the fourth drive assembly 322 including a fourth housing 3221, a fourth power output 3222, and a first transmission 3223. Fourth housing 3221 is rotatably coupled to boat clamp 3121 and fourth power output 3222 is slidably coupled to fourth housing 3221. The first transmission 3223 is rotatably connected to the fourth power output 3222 and fixedly connected to the first rotation shaft 3212. Thus, when the fourth power output member 3222 slides, the fourth base 3221 rotates relative to the boat holder 3121, and the first transmission member 3223 rotates relative to the fourth power output member 3222 and drives the first rotation shaft 3212 to rotate, so that the blade 321 can be rotated.

In some embodiments, fourth housing 3221 is a block of a cylinder and fourth power take-off 3222 is a piston rod of the cylinder. In other embodiments, the fourth base 3221 is a sliding rail of a linear module, and the fourth power output member 3222 is a sliding table of the linear module.

Referring to fig. 8, the boat base is generally rectangular. Referring to fig. 9 and 10, the boat table 311 is provided with a positioning member 3111, one side of the positioning member 3111 is a positioning side 31111, the positioning side 31111 is planar, one side of each boat-clamping member 3121 facing the other boat-clamping member 3121 is a boat-clamping side 31211, and the boat-clamping side 31211 is planar and perpendicular to the positioning side 31111. Thus, after the boat is placed on the boat table 311, the boat can be positioned with one side of the boat base abutting against the positioning side 31111. After the boat is positioned, the other two sides of the boat are parallel to the boat clamping sides 31211, so that the boat can be clamped and fixed by moving the two boat clamping pieces 3121 in opposite directions. Preferably, the two positioning members 3111 are provided with two positioning sides 31111 of the two positioning members 3111 opposite to each other, so that two sides of the base of the boat can abut against the positioning sides 31111 of the two positioning members 3111, respectively, and the two positioning members 3111 play a role in limiting the boat, thereby facilitating the boat clamping mechanism 31 to clamp the boat stably.

Referring to fig. 8 and 10, the blade 321 has a planar bearing side 3211, and the blade 321 is rotatable to a position in which the bearing side 3211 is parallel to the positioning side 31111. Rotating the blade support 321 to the support side 3211 parallel to the positioning side 31111 allows the support side 3211 to contact each of the battery cells in the boat one by one, thereby supporting each of the battery cells.

In other embodiments, the blade structure 32 may be a plate or rod structure secured to the boat 3121.

In other embodiments, the blade structure 32 may be disposed on the boat deck 311.

To prevent the battery plates from falling out of the boat, the boat is usually in a vertical state. In order to eject the battery cells in the boat, the boat needs to be turned to a horizontal state. Referring to fig. 12, the battery piece transferring and loading device 100 further includes two boat turning mechanisms 7, where the boat turning mechanisms 7 are disposed in one-to-one correspondence with the boat clamping devices 3. The boat turning mechanism 7 is provided with a second rotating shaft 71 capable of outputting rotary motion, and the boat bearing platform 311 of each boat clamping device 3 is fixedly arranged on the second rotating shaft 71 of the corresponding boat turning mechanism 7. In this way, the second transmission shaft rotates to drive the boat bearing platform 311 to rotate, so as to drive the boat clamped by the two boat clamping pieces 3121 to rotate, and further turn the boat to a horizontal state or a vertical state.

Referring to fig. 12, the boat turning mechanism 7 further includes a second transmission member 73 and a fifth driving assembly 72, and the fifth driving assembly 72 includes a fifth housing 721 and a fifth power take-off member 722. The fifth housing 721 is rotatably coupled to the switching table 4, and the fifth power output member 722 is slidably coupled to the fifth housing 721. The second transmission member 73 is rotatably connected to the fifth power output member 722 and fixedly connected to the second rotation shaft 71, and the second rotation shaft 71 is rotatably connected to the switching table 4. In fig. 12, the first boat 400 is in a horizontal state, the second boat 500 is in a vertical state, and accordingly, the two boat turning mechanisms 7 in fig. 12 are in different states. Comparing the states of the two boat turning mechanisms 7 in fig. 12, it can be seen that: when the fifth power output member 722 slides, the fifth seat 721 rotates relative to the switching table 4, and the second transmission member 73 rotates relative to the fifth power output member 722 and drives the second rotation shaft 71 to rotate, so as to drive the boat bearing table 311 to rotate, and further drive the boat clamped by the two boat clamping members 3121 to rotate, so that the boat is turned to a horizontal state or a vertical state.

In the embodiment shown in fig. 12, the boat table 311 is fixed to the second rotation shaft 71 by a centering member.

Preferably, referring to fig. 12, the fifth drive assembly 72 is a cylinder, the fifth housing 721 is a cylinder, and the fifth power take-off 722 is a piston rod. The second rotation shaft 71 is in the first state when the piston of the fifth power output member 722 is at zero point; when the piston of the fifth power output member 722 is at the end point, the second rotation shaft 71 is in the second state. The second state of the second rotation shaft 71 is rotated by 90 ° with respect to the first state. In other words, the fifth power output 722 rotates the second rotation shaft 71 through 90 ° during the movement of the piston of the fifth power output 722 from the zero point to the end point. In this way, the fifth drive assembly 72 can just turn the boat held by the boat holding device 3 by 90 °.

Referring to fig. 12, in the fifth drive assembly 72 on the right, the piston of the fifth power take-off 722 is in the zero position. In the fifth drive assembly 72 on the left, the piston of the fifth power take-off 722 is in the end position.
