Referring to fig. 1, the present invention provides a cell pressing device 10 and a cell transferring mechanism 100. The battery cell pressing device 10 includes a battery cell transfer mechanism 100, a transfer mechanism 200, an incoming material carrying mechanism 300, a hot press 400, and an unloading transfer mechanism 500.

The cell pressing device 10 is sequentially provided with a feeding station, a hot pressing station and a discharging station, and the feeding, pressing and discharging operations of the cell to be pressed can be sequentially completed on the three stations. The incoming material carrying mechanism 300 is disposed at the feeding station, and is configured to transfer the battery cell that completes the previous process to the feeding station. The supplied material carrying mechanism 300 can be driven by a motor screw pair, and grabbing of the battery cell is realized by a clamping jaw cylinder. Also, the position of the incoming material handling mechanism 300 is generally kept fixed.

The battery cell transfer mechanism 100 is used for clamping and releasing a battery cell to be pressed, and is arranged on the transfer mechanism 200. The battery cell transfer mechanism 100 can reciprocate between the loading station and the hot-pressing station under the driving of the transfer mechanism 200. Therefore, the electric core transfer mechanism 100 can clamp the electric core to be pressed on the loading station, and release the clamped electric core on the hot pressing station, so as to transfer the electric core to the chopping board of the hot press 400.

The transferring mechanism 200 generally includes a metal transferring support frame and a driving member, the metal transferring support frame is provided with a line rail, the battery cell transferring mechanism 100 can be installed by means of matching a sliding block with the line rail, and the position is transferred under the driving of the driving member. The feeding station, the hot pressing station and the discharging station shown in fig. 1 are arranged at intervals in the horizontal direction, so that the linear rail on the transfer mechanism 200 extends in the horizontal direction.

The discharging and transferring mechanism 500 is disposed on the transferring mechanism 200, and can be driven by the transferring mechanism 200 to reciprocate between the discharging station and the hot pressing station, so as to take out the battery cell pressed by the hot press 400. The blanking transferring mechanism 500 can be mounted on the transferring mechanism 200 by means of matching the slide block and the line rail, and is driven by the driving member. Moreover, the blanking mechanism 500 and the cell transferring mechanism 100 may share a wire track, or may use different wire tracks. Unloading transport mechanism 500 can in time take out electric core to raise the efficiency. Obviously, in other embodiments, the laminated battery cell may be taken out by other methods, such as manual methods, mechanical arms, and the like.

Specifically, in the present embodiment, the blanking transferring mechanism 500 includes a blanking base 510 and an adsorbing member 520. The suction member 520 is disposed on the lower base 510 and is slidable in a first direction with respect to the lower base 510.

The suction member 520 may be a vacuum suction member, and a negative pressure may be formed at a suction surface thereof by vacuum suction, thereby sucking up electricity. The adsorption member 520 slides in a first direction and can be close to or away from the surface of the anvil of the heat press 400. When the battery core is to be sucked, the adsorption piece 520 can be driven to be close to the hot press 400, so that the battery core can be smoothly sucked. When the discharging transfer mechanism 500 moves, the adsorption member 520 can be driven to move away from the hot press 400, so as to prevent the hot press 400 from affecting the transverse movement of the discharging transfer mechanism 500. The direction perpendicular to the drawing sheet shown in fig. 1 is the first direction.

Referring to fig. 2 to 4, a cell transferring mechanism 100 according to a preferred embodiment of the invention includes a support 110, a riser 120, and a cell clamping assembly 130.

The support 110 serves as a support and is generally formed of a metal plate. The riser 120 is mounted to the support 110, and the riser 120 is slidable in a first direction relative to the support 110. Specifically, the support 110 may be provided with a driving member (not shown) such as an air cylinder and a linear motor, and the vertical plate 120 may be slidably mounted on the support 110 via a wire rail and driven by the driving member.

The cell clamping assembly 130 is disposed on the vertical plate 120 and can clamp and release the cell. Specifically, the cell clamping assembly 130 opposite to the incoming material conveying mechanism 300 can clamp the cells to be pressed in the incoming material conveying mechanism 300. The vertical plate 120 slides along the first direction to drive the entire cell assembly 130 to move along the first direction, so that the cell assembly 130 is close to or far away from the hot press 400. Similarly, the vertical plate 120 slides along the first direction, so that the battery cell clamping assembly 130 can conveniently place the clamped battery cell to be pressed on the surface of the cutting board of the hot press 400. Meanwhile, the transverse movement of the cell transfer mechanism 100 driven by the transfer mechanism 200 is not affected.

Specifically, in the present embodiment, the plurality of cell clamping assemblies 130 are provided, and the plurality of cell clamping assemblies 130 are disposed at intervals on the vertical plate 120. The risers 120 may be elongated to facilitate the distribution of the plurality of cell assemblies 130. Every presss from both sides electric core subassembly 130 all can press from both sides an electric core and get, so electric core transport mechanism 100 once can press from both sides a plurality of electric cores of treating the pressfitting to can changeing synchronous the transporting to hot press 400 with a plurality of electric cores of treating the pressfitting and carry out the pressfitting, thereby show promotion production efficiency.

Correspondingly, the blanking transferring mechanism 500 in this embodiment includes a plurality of adsorbing members 520. The number of the absorption members 520 is generally equal to or greater than the number of the electric-clamping core assemblies 130, and the arrangement direction of the absorption members 520 is consistent with the arrangement mode of the electric-clamping core assemblies 130. Therefore, after the lamination of a plurality of battery cells transferred to the hot press 400 by the plurality of battery cell clamping assemblies 130 is completed, the discharging and transferring mechanism 500 can take out the plurality of battery cells at one time, thereby further improving the production efficiency.

As shown in fig. 1, six power clamp assemblies 130 are spaced apart from each other in the transfer direction of the transfer mechanism 200, i.e., in the horizontal direction, and the elongated vertical plates 120 also extend in the horizontal direction. Under the driving of the transferring mechanism 200, the six battery cell clamping assemblies 130 can be sequentially moved to be in butt joint with the incoming material conveying mechanism 300, so as to sequentially clamp the six battery cells to be pressed on the incoming material conveying mechanism 300, and transfer the six battery cells to the hot press 400. Six suction members 520 are also provided at intervals in the horizontal direction. After the lamination of the battery cells is completed, the blanking transfer mechanism 500 is driven by the transfer mechanism 200 to move to the hot-pressing station, and the six laminated battery cells can be respectively adsorbed by the six adsorption pieces 520.

Specifically, in this embodiment, the cell transfer mechanism 100 further includes a bottom plate 140, and the support 110 is mounted on the bottom plate 140 and is slidable relative to the bottom plate 140 along a second direction perpendicular to the first direction.

The base plate 140 may be a metal plate and is provided to the transfer mechanism 200. The support 110 slides in the second direction to move the riser 120 and the cell assembly 130 integrally relative to the hot press 400, thereby adjusting the relative position of the cell assembly 130 and the hot press 400. When the electric core assembly 130 arrives at the hot pressing station under the driving of the transfer mechanism 200, the electric core assembly 130 and the hot press 400 are adjusted to be in relative positions along the second direction support 110, so that the electric core assembly 130 moves to the range of the cutting board of the hot press 400 (namely, the upper part of the cutting board), and then the electric core can be smoothly transferred to the hot press 400. The vertical direction shown in fig. 1 is the second direction.

It should be noted that in other embodiments, the support 110 may be fixed in the second direction, and the position of the support 110 is calibrated in advance, so that the clamping core assembly 130 is moved to the hot pressing station and is just within the range of the hot press 400.

Further, in this embodiment, the battery cell transferring mechanism 100 further includes a longitudinal driving assembly 150, and the longitudinal driving assembly 150 includes a longitudinal driving member 151 and two rail sliders 152. Wherein two rail blocks 152 connect the base plate 140 and the support base 110 such that the support base 110 is slidable relative to the base plate. The longitudinal driving member 151 is disposed between the two rail sliders 152 and disposed on the base plate 140, and a driving end of the longitudinal driving member 151 is connected to the support 110, so as to drive the support 110 to slide.

The longitudinal driving member 151 may be a linear motor, an air cylinder or a motor screw pair; the rail slide 152 includes a slide rail and a slide block engaged therewith, the slide rail extending along the second direction. Moreover, the longitudinal driving member 151 is disposed between the two rail sliders 152, so that the support of the support base 110 during the sliding process is more balanced, which is beneficial to maintain the stability of the cell clamping assembly 130.

Referring to fig. 5 and 6, each clip core assembly 130 includes a clip member 131 and a holding member 132.

Wherein:

the clamping pieces 131 are multiple, and the multiple clamping pieces 131 can clamp multiple edges of the battery cell to be pressed. Specifically, the clamping member 131 may form a bayonet, a clamping groove, or the like, for clamping and fixing the edge of the electric core. The clamping pieces 131 can be expanded or contracted relative to each other to clamp or release the cells to be pressed. When the cell is clamped by the plurality of clamping members 131, the first direction is substantially perpendicular to the surface of the cell. That is, the surface of the cell in fig. 1 is substantially parallel to the plane of the drawing. Thus, when the battery cell assembly 130 moves along the first direction and transfers the battery cell to the surface of the anvil plate of the hot press 400, the contact area between the battery cell and the surface of the anvil plate of the hot press 400 is large, so that the battery cell is not easy to damage.

When the electrical core clamping assembly 130 is used for clamping an electrical core, the electrical core may be arranged in an area surrounded by the clamping members 131. Then, the plurality of clamping members 131 are retracted until each clamping member 131 comes into contact with and clamps the edge of the cell, thereby fixing the cell. When the clamping members 131 expand outward, the distance between the clamping members 131 increases, so that the clamping members 131 cannot continuously clamp the edge of the battery cell, and the battery cell is released.

For a rectangular battery cell, two opposite edges of the battery cell are clamped to realize fixation. Therefore, the clip core assembly 130 in this embodiment includes two oppositely disposed clips 131, namely a first clip 131A and a second clip 131B. It should be noted that the first clamping member 131A and the second clamping member 131B may have the same structure.

It should be noted that in other embodiments, there are other possibilities for the number and arrangement of the clamping members 131. For example, two sets of two opposite clamping members 131 may be provided to clamp four edges of the cell.

The holding member 132 is provided between the clamping members 131. Furthermore, the abutting element 132 is configured to provide an abutting force to the to-be-pressed battery cell clamped between the clamping elements 131 along the first direction. Under the action of the supporting force, the battery cell to be pressed can be pressed and attached to the surface of the chopping board of the hot press 400. Moreover, since the abutting member 132 is located between the clamping members 131, the action point of the abutting force is located in the middle of the cell.

Specifically, in the present embodiment, the supporting member 132 includes a supporting driving member 1321 and a supporting block 1322 disposed at the driving end of the supporting driving member 1321. The abutting driving member 1321 may drive the abutting block 1322 to move along the first direction, so as to provide an abutting force to the battery cell clamped between the clamping members 131. The abutting driving member 1321 may be an air cylinder or a linear motor, and may be fixed to the vertical plate 120 by a supporting plate (not shown).

The process of transferring the battery cell to be pressed to the hot press 400 by the battery cell transferring mechanism 100 is as follows:

the battery cell transferring mechanism 100 firstly clamps a battery cell at a feeding station and moves to a hot-pressing station under the drive of the transferring mechanism 200; the support 110 slides towards the hot press 400 along a first direction, so that the clamping piece 131 clamping the battery cell is close to the surface of the cutting board of the hot press 400; after the clamping member 131 moves to the proper position (the end of the clamping member 131 is close to but not in contact with the surface of the anvil of the hot press 400), the abutting driving member 1321 is actuated to press the battery cell against the surface of the anvil of the hot press 400 by the abutting block 1322. At this time, only the surface of the middle part of the battery cell falls on a chopping board of the hot press 400, and the edge of the battery cell is still clamped by the clamping piece 131; the plurality of clamping members 131 are then splayed relative to each other, and the clamping members 131 are withdrawn from beneath the cells, thereby allowing the entire surface of the cells to fall onto the anvil of the hot press 400. Meanwhile, due to the abutting action of the abutting piece 132, the battery cell does not shift when the clamping piece 131 is pulled away, so that the battery cell is reliably transferred.

Referring to fig. 5 again, in the present embodiment, each clamping member 131 includes a connecting plate 1311, a pressing driving member 1312, and a pressing block 1313. Wherein:

the end of the connecting plate 1311 is bent to form a bent plate 13112, and a pressing block 1313 is provided at the driving end of the pressing driver 1312. The compression drive 1312 is provided on the connection plate 1311. Furthermore, a clamping groove (not shown) capable of clamping the edge of the battery cell to be pressed is formed between the pressing block 1313 and the bent plate 13112, and the pressing driving member 1312 can drive the pressing block 1313 to move along the first direction.

The structure of the pressing driving member 1312 and the pressing block 1313 is similar to that of the abutting member 132, and the pressing driving member 1312 may be an air cylinder, a linear motor or the like. The clamp block 1313 is moved in a first direction to adjust the opening of the clamp slot up or down. As the cell assembly 130 grips the cell, the compression drive 1312 drives the compression block 1313 towards the bend plate 13112, thereby reducing the opening of the clamp slot so that the clamp 131 grips the edge of the cell. When the cell clamping core assembly 130 needs to release the cell, the pressing driving member 1312 can drive the pressing block 1313 to move away from the bending plate 13112, so as to enlarge the opening of the clamping groove, so that the clamping member 131 can be conveniently pulled away, and unnecessary abrasion to the cell can be avoided.

It should be noted that in other embodiments, the clamping member 131 may take other forms. For example, the clamping member 131 is formed with a clamping groove having a fixed opening size, and the clamping groove has a wedge shape. As the plurality of clamping members 131 are retracted, the inner walls of the clamping grooves may gradually clamp the edges of the cells.

Further, referring to fig. 2 and fig. 3 again, in this embodiment, the battery cell transferring mechanism 100 further includes a clamping driving component 160, and the clamping driving component 160 is disposed on the vertical plate 120 and is in transmission connection with the connecting plate 1311. Also, the clamp driving assembly 160 may drive the plurality of clamping members 131 to slide in a third direction perpendicular to the first direction to expand or contract the plurality of clamping members 131 outward or inward with respect to each other.

Because the clamp groove is spacing and realize pressing from both sides tight to electric core through bent plate 13112 and compact heap 1313 along the first direction, consequently, from the third direction translation clamping piece 131 with the first direction vertically, can avoid clamping piece 131 to expand outward and contract in-process and the edge production of electric core and collide with in the inside, and then prevent to cause the damage to electric core. Specifically, the third direction may be the same as the second direction, or may be perpendicular to the second direction. The third direction in this embodiment is perpendicular to the first direction and the second direction, i.e. the horizontal direction shown in fig. 1.

Specifically, in the present embodiment, the clamping driving assembly 160 includes a lateral driving member 161 and a lateral sliding plate 162. The lateral sliding plates 162 are slidably provided to the risers 120, and the lateral driver 161 can drive the lateral sliding plates 162 to slide in the third direction. The lateral drive member 161 may be a linear motor, an air cylinder, and the lateral slide plate 162 may be mounted to the riser 120 by a wire track.

The transverse sliding plate 162 is fixedly connected to the connecting plate 1311, so as to drive the clamping member 131 to slide in the third direction.

It should be noted that in other embodiments, the plurality of clamping members 131 can be expanded and contracted in other manners. For example, the ends of the clamping members 131 far from the clamping groove are hinged by hinges, so that the clamping members 131 can be expanded and contracted by rotating with each other. At this time, the plurality of clamping members 131 are structured like a jaw.

In this embodiment, the first clamping member 131A and the second clamping member 131B are spaced in the third direction, and can be driven by the clamping driving assembly 160 to move toward or away from each other in the third direction. The first clamping member 131A and the second clamping member 131B may be driven by the same clamping driving assembly 160 (e.g., a clamping jaw air cylinder), or may be driven by different clamping driving assemblies 160 (e.g., two air cylinders are used to drive the first clamping member 131A and the second clamping member 131B to translate, respectively).

Further, in the present embodiment, the clamping driving assembly 160 is two, and the two lateral sliding plates 162 are spaced apart in the first direction. Since there are a plurality of cell core assemblies 130, the cell transferring mechanism 100 includes a plurality of first clamping members 131A and a plurality of second clamping members 131B. Wherein the connecting plates 1311 of the first clamping members 131A are fixed to one of the lateral sliding plates 162, and the connecting plates 1311 of the second clamping members 131B are fixed to the other lateral connecting plate 1311.

That is, the clamping core assemblies 130 share two clamping driving assemblies 160, one clamping driving assembly 160 can drive the first clamping members 131A to move synchronously, and the other clamping driving assembly 160 can drive the second clamping members 131B to move synchronously. Therefore, the number of components in the cell transfer mechanism 100 can be reduced, and the structure thereof can be made compact.

In the above-mentioned cell pressing device 10 and cell transferring mechanism 100, the plurality of clamping members 131 can be retracted each other and respectively clamp the edge of the cell to be pressed, so as to clamp the cell to be pressed on the cell clamping assembly 130. The vertical plate 120 slides along the first direction, so that the clamping member 131 clamping the battery cell to be pressed is close to the surface of the cutting board of the hot press 400. After the clamping member 131 moves in place, the abutting member 132 acts, and the battery cell to be pressed is pressed against the surface of the cutting board of the hot press 400 under the action of the abutting force. The clamping members 131 are driven to expand outwards, so that the clamping members 131 are drawn out from between the battery cell and the hot press 400, and the battery cell to be pressed keeps unchanged in position under the action of the abutting members 132, and is finally integrally carried on the surface of a cutting board of the hot press 400. It can be seen that in order to realize the cell transfer, the surface of the chopping block of the hot press 400 does not need to be provided with an avoiding groove. Moreover, under the action of the abutting member 132, the position of the battery cell to be pressed is always stable in the process of transferring the battery cell to the hot press 400. Therefore, the above-described cell transfer mechanism 100 can realize reliable cell transfer.
