Then, side end plates are bonded and fixed at the left and right ends to form a battery assembly. Then, the front and rear side walls of the battery assembly need to be welded and fixed with side baffles so that the two side baffles and the two side end plates form a rectangular outer frame and are located on the periphery of the blade battery to achieve protection.

[0003] The existing side baffles are welded and fixed to the battery assembly by a person who generally needs to manually press one of the side baffles against one side of the battery assembly and against one side of the two side end plates.

[0019] Figure 3 This is a partial cross-sectional view of the utility model at a different angle. Specific implementation method:

[0020] For example, see Figures 1 to 3 As shown, a blade battery cell side panel welding auxiliary tooling includes a fixed base plate 10, a middle horizontal plate 11 extending left and right is fixed to the middle of the top surface of the fixed base plate 10, and side fixing plates 12 are fixed to the left and right parts of the top surface of the fixed base plate 10;

[0021] The battery assembly 100, consisting of a plurality of blade cells 101 bonded and fixed to each other and stacked left and right, and side end plates 102 bonded to the left and right ends, is placed on the top surface of the middle horizontal plate 11. The front and rear of the battery assembly 100 extend out of the front and rear sides of the middle horizontal plate 11. The two side fixing plates 12 are each equipped with an end adjustment mechanism 20, and the pressure plate 21 of the end adjustment mechanism 20 presses against the outer side wall of the corresponding side end plate 102.

[0022] An upper support frame 30 is fixed to the middle of the top surface of the fixed base plate 10, and a pressing cylinder 31 is fixed to the middle of the top surface of the top plate of the upper support frame 30. The bottom end of the push rod of the pressing cylinder 31 extends out of the bottom surface of the top plate of the upper support frame 30 and is fixed to an upper pressing plate 32. A protective plate 33 is fixed to the middle of the bottom surface of the upper pressing plate 32, and the bottom surface of the protective plate 33 presses against the top surface of the battery assembly 100;

[0023] Vertical connecting plates 34 are fixed on the front and rear side walls of the upper pressure plate 32, and side clamping cylinders 35 are fixed on the middle of the outer side walls of the vertical connecting plates 34. The ends of the push rods of the side clamping cylinders 35 extend out of the inner side walls of the vertical connecting plates 34 and are fixed with clamping plates. A grabbing assembly 40 is fixed on the inner side of the clamping plate, and the fixed side plates 200 to be welded are on the grabbing assembly 40. The inner side walls of the two fixed side plates 200 are pressed against the front and rear side walls of the battery assembly 100, and the ends of the fixed side plates 200 are pressed against the front side walls or right side walls of the corresponding side end plates 102.

[0024] Specifically, the end adjustment mechanism 20 includes a transverse screw 22, which is threaded into a central threaded through-hole in the corresponding side fixing plate 12. The inner end of the transverse screw 22 extends beyond the inner sidewall of the corresponding side fixing plate 12 and is movably connected to the pressure plate 21. The outer end of the transverse screw 22 extends beyond the side fixing plate 12 and is secured to a rotating portion. A compression spring 1 is inserted into the transverse screw 22, with one end of the compression spring 1 applying force to the inner end surface of the corresponding side fixing plate 12 and the other end applying force to the outer end surface of the pressure plate 21. The compression spring 1 increases the pressure on the pressure plate 21 and prevents the transverse screw 22 from loosening.

[0025] Furthermore, a self-lubricating layer is fixed to the middle portion of the bottom surface of the pressure plate 21. Downward-extending protrusions are formed on the front and rear portions of the bottom surface of the pressure plate 21. An inner self-lubricating layer is fixed to the inner sidewalls of the protrusions. The middle horizontal plate 11 is positioned between the two protrusions. The bottom surface of the self-lubricating layer presses against the top surface of the middle horizontal plate 11, and the inner self-lubricating layer clings to the front and rear sidewalls of the middle horizontal plate 11. The inner and outer self-lubricating layers ensure that the pressure plate 21 can move stably along the middle horizontal plate 11, reducing friction and facilitating smooth sliding.

[0026] Furthermore, a protective end plate 23 is fixed to the inner end surface of the pressure plate 21, and the end surface of the protective end plate 23 presses against the outer end surface of the corresponding side end plate 102 of the battery assembly 100. The protective end plate 23 can be made of a protective and non-slip material such as rubber (which has a certain elastic deformation, but the deformation is within a controllable range, that is, the deformation does not substantially affect the pressing of the pressure plate 21). The protective end plate 23 can reduce wear or scratches on the surface of the side end plate 102 during pressing.

[0027] Furthermore, the upper support frame 30 includes vertical columns fixed on the left and right ends of the front and the left and right ends of the rear of the middle part of the top surface of the fixed base plate 10, the top plate is fixed on the top surface of the four vertical columns, and multiple guide rods are fixed on the top surface of the upper pressure plate 32, and the guide rods are inserted into the vertical guide through holes formed on the top plate of the upper support frame 30.

[0028] Furthermore, the grabbing assembly 40 includes a side pressure plate 41, the outer wall surface of the side pressure plate 41 is fixed on the inner end surface of the pressure plate, and at least one dual-axis cylinder 42 is fixed on the outer side walls of the upper and lower parts of the side pressure plate 41 (in this embodiment, dual-axis cylinders 42 are installed on the left and right parts of the upper and lower parts of the side pressure plate 41), and the ends of the push rods of all dual-axis cylinders 42 are fixed with clamping bars 43, and the outer side wall of the fixed side plate 200 to be welded is tightly attached to the inner end surface of the corresponding side pressure plate 41, and the top surface of the fixed side plate 200 is pressed against the bottom surface of the upper clamping bar 43 (in this embodiment, the two upper clamping bars 43), and the bottom surface of the fixed side plate 200 is pressed against the top surface of the lower clamping bar 43 (in this embodiment, the two lower clamping bars 43). Among them, the anti-slip protective layer is fixed on the bottom surface of the upper clamping bar 43, and the anti-slip protective layer is fixed on the top surface of the lower clamping bar 43, so that the fixed side panel 200 is clamped between the upper and lower corresponding anti-slip protective layers. Among them, the anti-slip protective layer can be made of anti-slip materials such as rubber (which has a certain elastic deformation, but its deformation amount is within a controllable range, that is, its deformation amount basically does not affect the clamping position of the fixed side panel 200).

[0029] Furthermore, a plurality of outer guide rods are fixed on the outer side wall of the side pressing plate 41 , and the outer guide rods are inserted into the transverse guide through holes formed on the corresponding vertical connecting plates 34 .

[0030] All cylinders in this embodiment are connected to the pneumatic system through connecting pipes (the pneumatic system consists of components such as solenoid valves, air pumps, and air tanks). All electrical equipment in the pneumatic system is electrically connected to the control host through electrical connecting lines and is controlled by the control host. This is a conventional structure and will not be described in detail here.

[0031] When the present embodiment is in use, it first places the battery assembly 100 (this battery assembly 100 has been processed and assembled in the previous processing equipment) consisting of a plurality of blade cells 101 bonded and fixed to each other and stacked left and right, and side end plates 102 bonded to the left and right ends thereof) on the top surface of the middle horizontal plate 11. Then, the two transverse screws 22 are rotated so that the end faces of the protective end plates 23 are pressed against the outer end faces of the corresponding side end plates 102 of the battery assembly 100 to clamp and fix it. It is also necessary to ensure that the battery assembly 100 is clamped in the center. Scales can be engraved on the front or rear top surface of the middle horizontal plate 11. The position of the two pressing plates 21 can be understood by the scales corresponding to the positions of the two pressing plates 21, so that the battery assembly 100 can be conveniently clamped in the center. Then, the push rod of the pressing cylinder 31 is pushed so that the bottom surface of the protective plate 33 is pressed against the top surface of the battery assembly 100 to further press it.

[0032] Then, the two fixed side plates 200 are pressed against the inner end surfaces of the corresponding side clamping plates 41, and the two push rods of the corresponding double-axis cylinders 42 are retracted, so that the fixed side plates 200 are clamped between the two clamping bars 43, wherein the size of the fixed side plates 200 is consistent with the size of the side clamping plates 41. Therefore, when installing them, it is only necessary to ensure that the fixed side plates 200 are completely aligned and pressed against the inner side walls of the corresponding side clamping plates 41, and then the two push rods of the double-axis cylinders 42 are retracted to fix them. Then, the push rod of the side clamping cylinder 35 is pushed to press the fixed side plates 200 It leans against the front side wall or right side wall of the battery assembly 100, and its end is pressed against the front side wall or right side wall of the corresponding side end plate 102. When the tool is manufactured, the position of the side clamping plate 41 corresponds to the position of the fixed side plate 200 to be welded to the front side wall or right side wall of the battery assembly 100. Therefore, it is only necessary to ensure that the fixed side plate 200 that needs to be welded later is fixed to its side clamping plate 41, that is, it can be ensured that its end is pressed against the front side wall or right side wall of the corresponding side end plate 102, and its top and bottom surfaces are aligned with the top and bottom surfaces of the battery assembly 100.

[0033] Then, the fixed side plate 200 can be manually welded to the pressing part of the side end plate 102 (if a robot is installed, automatic welding can be achieved through the robot operation). The two fixed side plates 200 can be welded in sequence. One clamping can complete the welding of the two fixed side plates 200 of a battery assembly 100. The processing efficiency is high, and it only requires one person to operate, which is very convenient.

[0034] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
