Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 and 2, the present application discloses a press pin 10, which includes a press head 11 capable of pressing against a material 1 to be welded; the pressure head 11 is sunk against the end surface of the material 1 to form a groove 14; the side wall of the groove 14 is provided with a through hole 15, and the through hole 15 is communicated with the groove 14 and the outside, so that air flow can conveniently circulate in the groove 14.
It should be explained that the pressing pin 10 is used to press the material 1 to be welded to fix the position and/or the position state of the material 1. For example, when the material 1 is a battery string, the battery string is formed by connecting a plurality of battery pieces and welding strips in series; before welding, the connection between the battery piece and the welding strip is not fixed, and the battery piece and the welding strip are easy to relatively displace; for this reason, it is necessary to press the solder strip onto the battery piece by the pressing pin 10, to fix the relative position of the battery piece and the soldering station, so that the soldering mechanism can accurately act on the battery string and fuse the solder between the battery piece and the soldering station, so as to bond the battery piece and the soldering station together. Wherein, the battery string is fixed at a welding station (i.e. a station where a welding mechanism performs welding work on the material 1), namely, the position of the material 1 is fixed by a pressing needle 10; and the relative position of the battery piece and the welding strip is fixed, namely the position state of the material 1 is fixed through the pressing pin 10.
In addition, when the material is welded at high temperature, the pressing pin 10 also has a heat conduction effect. It can be known that, because the pressing pin 10 presses on the material 1 to be welded, if the pressing pin 10 cannot conduct heat, the position where the pressing pin 10 presses against the material 1 is difficult to weld; therefore, the presser pin 10 can be made of a metal material that is easily heat conductive. In the welding process, the part of the material 1 which is not abutted by the pressing pin 10 is directly heated; and after receiving the heat output by the welding mechanism, the pressing pin 10 heats the pressed part of the material 1 through self heat conduction.
As can be easily understood, since the pressing pin 10 presses the material 1, a certain force is applied to the material 1; after welding, the material is easy to attach to the end face of the pressure head 11 and leaves along with the pressure pin 10, and the welding effect is further damaged. For this reason, it is necessary to reduce the area of the end surface of the pressing head 11 against the material 1, and by reducing the contact area of the pressing head 11 and the material 1, the possibility of the two being attached is reduced.
By forming the groove 14 on the end surface of the pressing head 11, referring to fig. 1 and 2, it can be seen that when the pressing head 11 abuts against the material 1, the notch of the groove 14 is finally contacted with the material 1, only the rest end surface of the notch can contact the material 1, and the part provided with the groove 14 does not contact the material 1; thus, the provision of the groove 14 can reduce the area of the ram 11 contacting the material 1.
In addition, by enlarging or reducing the notch of the groove 14, the area and the position of the pressure head 11 contacting the material 1 can be adjusted according to specific conditions.
It should be explained further that, only when the end face of the pressing head 11 is provided with the groove 14, the notch of the groove 14 is "covered" by the material 1 after the pressing head 11 abuts against the material 1; at this time, the groove 14 is almost closed, and gas is difficult to circulate in the groove. When the material 1 is welded at high temperature, the temperature of the gas enclosed in the groove 14 is difficult to rise, and the temperature difference between the gas and the outside gas, even the outer wall of the pressing pin 10, can affect the shielded material 1 facing the groove 14, so that the part of the material 1 is difficult to receive the required temperature, and finally the welding is hindered.
Through set up through recess 14, the inside and outside through-hole 15 of intercommunication at recess 14 lateral wall, during high temperature welding, the gas in the recess 14 flows out recess 14 through-hole 15, and the gas of high temperature also can get into recess 14 through-hole 15, and then guarantees that the material 1 part just to recess 14 receives required temperature. At this moment, the pressing pin 10 can better realize heat conduction, ensure that the part of the material 1 pressed or shielded by the pressing pin can better receive heat and realize welding, and further ensure the welding effect.
Further, the groove 14 is a tapered groove; the caliber of the groove 14 is gradually reduced from the end face of the pressure head 11 to the inside.
With particular reference to fig. 2, the taper of the groove 14 is inward. By arranging the groove 14 as a tapered groove, on one hand, the volume of the groove 14 can be reduced under the condition of ensuring the groove depth, and then the amount of gas retained in the groove 14 is reduced, so that the rapid ventilation is facilitated in the welding process; on the other hand, along with the continuous reduction of recess 14 bore, the pressure head 11 outer wall that forms recess 14 is constantly thickened, so, through-hole 15 can be seted up in the place that the outer wall is thicker, and then guarantees the stability of pressure head 11 structure, when avoiding pressure head 11 to support the pressure material, because through-hole 15 position is difficult to the bearing, leads to pressure head 11 to be destroyed by pressure.
Further, four through holes 15 are provided at equal intervals on the side wall of the groove 14.
Referring to fig. 1 and 2 in particular in combination, it is readily understood that the more the inside of the groove 14 is exposed by the through-hole 15, the faster the gas inside the groove 14 exchanges with the gas outside. Therefore, four through holes 15 are formed in the side wall of the groove 14 at equal intervals, and the four through holes 15 are opposite to each other in pairs, so that gas circulation can be conveniently and rapidly realized, and the stability of the structure of the pressure head 11 can be maintained to a certain extent.
Of course, the number and size of the through holes 15 formed in the side wall of the groove 14 may be varied according to the requirement of gas circulation, and the application is not limited.
With continued reference to fig. 3-5, the present application further discloses a welding device comprising: a pressing plate 20, wherein the pressing pin 10 is arranged on the pressing plate 20; the first driving mechanism 30 is connected with the pressing plate 20 and can drive the pressing plate 20 to be close to press the material 1 to be welded until the pressing needle 10 presses the material 1; the welding mechanism 40 can weld the material 1.
In the welding device, a pressing plate 20 is used for pressing the material 1 to be welded. In one embodiment, a mechanism (not shown) for conveying the material 1 can move the material 1 toward the pressing plate 20 to press the material 1 against the pressing plate 20, so as to achieve the pressing of the material 1 by the pressing plate 20. However, with this embodiment, the material 1 moves towards the pressing plate 20, and during the movement, the material 1 may be displaced, thereby affecting the pressing of the pressing plate 20 and the welding of the welding mechanism 30.
For this reason, in another embodiment, by providing the first driving mechanism 30 to move the pressing plate 20 to be close to or far away from the material 1, the material 1 can be prevented from moving, and thus the material 1 can be prevented from being displaced, and the pressing plate 20 can be ensured to accurately press the material.
The first driving mechanism 30 may be a linear module, an electric cylinder, or other driving members.
In a specific embodiment, the first driving mechanism 30 is used for driving the pressing plate 20 to move in the vertical direction, so that the material 1 is arranged in a horizontal state, and the state of the material 1 to be welded is optimized; at the moment, the material 1 reaches the welding station and is positioned under the pressure plate 20; the first driving mechanism 30 drives the pressing plate 20 to move downwards and press the material 1 tightly; at the end of welding, the first driving mechanism 30 drives the press plate 20 to move upwards and loosen the materials 1, so that the welded materials 1 are discharged, and the next material 1 to be welded comes to the welding station.
The pressing plate 20 is mainly used for installing the pressing pins 10, and when the pressing pins 10 press the material 1, the main body of the pressing plate 20 can be suspended above the material 1. Welding mechanism 40 produces high temperature, when utilizing high temperature to weld material 1, if clamp plate 20 is the structure that can cover material 1 surface, clamp plate 20 can separate welding mechanism 40 and material 1, and then influences the high-efficient welding of material 1. For this purpose, in one embodiment, the pressure plate 20 is provided with a through mounting channel 21; a plurality of groups of pressing pins 10 are arranged in the mounting channel 21 side by side along the first direction.
Referring specifically to fig. 6, since the installation passage 21 is through, it may expose the material 1 thereunder so that the welding mechanism 40 above the pressure plate 20 can weld the material 1 through the installation passage 21.
In addition, the presser pin 10 is mounted in the mounting passage 21, and can efficiently receive heat generated by the welding mechanism 40. In order to facilitate the installation of the pressing pin 10, a plurality of installation frames 22 are arranged in the installation channel 21 at intervals; the mounting frames 22 are arranged side by side along a first direction and are respectively used for mounting a group of pressing pins 10; the mounting frame 22 is mounted at both ends thereof on both sides of the mounting passage 21.
In a specific embodiment, the material 1 is a battery string (for the specific structure of the battery string, the above is referred to, and the description is omitted), and for the battery string, a plurality of solder strips are arranged side by side on one battery sheet; the first direction is the arrangement direction of a plurality of welding strips; referring to fig. 6, "first direction" is the illustrated left-right direction; in the simplest case, one group comprises only one pressing pin 10, and each pressing pin 10 can press a solder strip against a cell plate.
Of course, in other embodiments, the "first direction" may be varied according to the welding requirements of the material 1; the "first direction" is a direction in which the material 1 is arranged when the material 1 has a plurality of positions to be welded, and the present application is not limited in particular.
When the material 1 is a battery string, the solder strip on the battery piece has a certain length, and in order to compress the solder strip with a certain length, a group of press pins 10 comprises a plurality of press pins 10 arranged at intervals along the second direction; the plane formed by the first direction and the second direction is parallel to the surface of the material 1 to be welded.
Specifically, the "second direction" is an extending direction of the solder ribbon, for example, the vertical direction shown in fig. 6. During welding, the welding mechanism 40 welds one battery piece at a time, and a plurality of welding strips overlapped on the battery piece are jointed with the battery piece; at this time, the first direction is a direction in which a plurality of solder strips are arranged, and the second direction is an extending direction of each solder strip itself, and in order to press the solder strips onto the battery piece, the pressing pins 10 have a plurality of rows and a plurality of columns, so as to ensure that the position and the position state of each solder strip are accurate.
Of course, in other embodiments, the "second direction" may be varied according to the welding requirements of the material 1; the "second direction" is an extending direction of a position to be welded of the material 1, and the application is not limited in particular.
Further, when the pressing pin 10 presses the material 1, if the pressing pin directly and rigidly presses the material 1 under the driving of the first driving mechanism 30, the material 1 may be damaged by pressure or the pressing pin may collide with the material 1 to damage the end surface thereof. For this reason, referring to fig. 1 to 6, the press pin 10 is divided into three sections, which are a press head 11, a shaft 12 and a cap 13 in sequence; the pressing plate 20 is provided with a mounting hole 23, and the rod body 12 penetrates through the mounting hole 23 and can move along the mounting hole 23; the pressure head 11 and the cap 13 respectively penetrate out of two ends of the mounting hole 23; an elastic piece 16 is arranged between the shaft body 12 and the mounting hole 23; when the pressing pin 10 continuously presses the material 1, the pressing head 11 presses the material 1, and the rod body 12 moves away from the material 1 along the mounting hole 23, so that the elastic element 16 is compressed.
The diameters of the pressure head 11 and the cap 13 are larger than the diameter of the mounting hole 23, so that the pressure pin 10 can be prevented from penetrating out of the mounting hole 23. And the elastic member 16 may be a spring; the spring is sleeved on the rod body 12, one end of the spring is abutted with the pressure head 11, and the other end of the spring is abutted with the peripheral side of the mounting hole 23 and the outer wall of the pressure plate 20; as the shaft 12 moves along the mounting hole 23 away from the material 1, the ram 11 compresses the spring, causing the spring to compress between the ram 11 and the pressure plate 20.
It can be seen that when the first driving mechanism 30 drives the pressing plate 20 to move towards the material 1, the pressing pin 10 is continuously close to contact with the material 1; when the pressing pin 10 just contacts the material 1, no pressure is applied to the material 1, and the material 1 cannot be pressed tightly; for this purpose, the first driving mechanism 30 needs to drive the pressing plate 20 to move continuously towards the material 1 until the pressing pin 10 presses the material; in the process that the pressing pin 10 continuously presses against the material 1, as the rod body 12 can move in the mounting hole 23, the pressing plate 20 is continuously close to the material 1, the pressing pin 10 is not moved relative to the material 1, and the rod body 12 and the cap 13 are continuously far away from the pressing plate 20; at this time, as the shaft 12 continuously penetrates through the mounting hole 23, the elastic member 16 is compressed, the elastic member 16 tends to restore to its original shape, and thus the generated reverse acting force can enable the pressing head 11 to press the material 1.
Through setting up elastic component 16 and mobilizable tucker 10, can make tucker 10 elasticity support and press material 1, and then ensure safe and reliable when the two interact.
Through setting up lamp house 41, can form a comparatively inclosed space when protection, installation heating member 42 to keep the temperature in the space, make heating member 42 heat up fast and have the heat preservation effect.
Of course, the lamp box 41 is also communicated with an air blowing mechanism (not shown) which can blow off waste gas generated in the welding process; in addition, the lamp box 41 is also communicated with a cooling mechanism (not shown), and after welding is finished, the material 1 can be blown to rapidly cool the material 1, so that the welding position of the material 1 is rapidly shaped.
Wherein, the heating element 42 can adopt an infrared lamp, and the infrared lamp is used for irradiating and heating to realize welding; or, the heating element 42 may also be a heating rod, which can heat the inside of the lamp box 41, so that the temperature in the box is raised, and welding is realized.
In normal welding operations, the position of the welding mechanism 40 may be fixed; the lamp box 41 has a certain internal space, and the heating element 42 is suspended at the top in the lamp box 41; the pressing plate 20 is also provided in the lamp box 41 and can be moved in the lamp box 41 to approach or depart from the welding station by the drive of the first drive mechanism 30. The first driving mechanism 30 drives the pressing plate 20 to be far away from the welding station, and the material 1 to be welded can enter the lamp box 41 and reach the welding station; the first driving mechanism 30 drives the pressing plate 20 to move towards the welding station to press the material 1; the heating member 42 generates heat to realize welding; the heating element 42 stops working, the material 1 is shaped, and the first driving mechanism 30 drives the pressing plate 20 to be far away from the welding station, so that the welded material 1 is discharged, and the next material 1 to be welded enters the welding station. It should be added that, in the process, after the welded material 1 is fed, the heating element 42 can start heating, and it is not necessary to wait until the pressing plate 20 presses the material 1 and then heat the material, so as to accelerate the welding process.
To facilitate maintenance or refurbishment of the welding mechanism 40, the welding device provided herein further includes a second drive mechanism 50 coupled to the welding mechanism 40 and capable of driving the welding mechanism 40 toward or away from the platen 20.
By providing the second drive mechanism 50, the welding mechanism 40 can be independently moved relative to the platen 20 to facilitate operations other than welding to the welding mechanism 40 or to the platen 20.
The second driving mechanism 50 may be a linear module, an electric cylinder, or other driving members.
In some embodiments, the second drive mechanism 50 may also be used during the welding process; at this time, the welding mechanism 40 can be far away from the welding station like the pressure plate 20, so that the material 1 can be loaded and unloaded conveniently; and when the material 1 is in place, the welding station is approached, and the welding is realized.
The welding device provided by the application further comprises a feeding mechanism 60 capable of conveying the material 1 to the pressure plate 20 and the welding mechanism 40 (i.e. the welding station); during feeding, the first driving mechanism 30 drives the pressing plate 20 to be far away from the feeding mechanism 60, so that the feeding mechanism 60 can feed the material 1 to be welded to the lower part of the pressing plate 20; after the material 1 is in place, the first driving mechanism 30 drives the pressing plate 20 to approach the feeding mechanism 60 until the pressing pin 10 presses the material 1.
The feeding mechanism 60 may be a conveying member such as a conveyor belt, a conveying roller, or a conveying platform, as long as it can convey the material 1 to be welded to the welding station.
Similarly, the welding device provided by the application can also comprise a blanking mechanism which can receive and transfer the welded material 1 at the welding station; the blanking mechanism can also adopt conveying members such as a conveying belt, a conveying roller, a conveying platform and the like.
To simplify the apparatus, the feeding mechanism 60 and the blanking mechanism may be integrated (for convenience of description, the integrated mechanism is also referred to as "feeding mechanism 60" in this embodiment), and the welding station is located on the feeding mechanism 60.
Specifically, the feeding mechanism 60 may adopt a conveyor belt assembly, which includes a driving wheel, a driven wheel and a conveyor belt sleeved on the driving wheel and the driven wheel; the action wheel is rotatory by the driving piece drive, can drive from the driving wheel through the conveyer belt and follow the commentaries on classics, and then makes the conveyer belt circulate forward. The conveyor belt passes through the welding mechanism 40; the material 1 is arranged on the upper surface of the conveyor belt and is driven by the conveyor belt to move towards the welding mechanism 40; when the material 1 reaches the welding station, the material is just below the pressure plate 20 and the welding mechanism 40; the conveyor belt assembly stops working, so that the material 1 stays at the welding station, and the first driving mechanism 30 drives the pressing plate 20 to press the material 1, so that the pressing pin 1 is pressed against the material 1; meanwhile, the welding mechanism 40 conducts heat through the pressing plate 20 and the pressing pin 1, so as to weld the material 1. After the welding is finished, the conveyor belt assembly works again, the material 1 is conveyed forwards continuously, the welded material 1 leaves the welding station, and the other material 1 to be welded reaches the welding station.
