Two adjacent side panels of the plurality of side panels are connected by welding. The weld formed by welding may have defects such as burrs, and the battery processing equipment needs to be used to further process the welded battery.

[0003] How to improve the processing quality of batteries is a technical problem that needs to be solved urgently. Summary of the invention

[0004] In view of the above problems, the present application provides a battery processing equipment and a battery production line to improve the processing quality.

[0005] In the first aspect, the present application provides a battery processing equipment, including a tray, a processing device and a positioning mechanism, wherein the tray is used to carry the battery to be processed and the tray is movably arranged in the conveying direction to reach or leave the processing position, and the tray includes a first positioning structure. The processing device is used to process the battery to be processed. The positioning mechanism is arranged below the tray, and the positioning mechanism has a positioning plate and a lifting mechanism, the positioning plate includes a second positioning structure, and the lifting mechanism is used to drive the positioning plate to rise and fall. If the tray reaches the processing position, the lifting mechanism drives the positioning plate to rise so that the first positioning structure and the second positioning structure cooperate; if the processing device completes the processing of the battery to be processed, the lifting mechanism drives the positioning plate to descend so that the second positioning structure is separated from the first positioning structure.

[0006] Among them, the lifting mechanism includes a moving wheel and a wedge block, the wedge block has an inclined surface, the moving wheel is arranged on the lower side of the positioning plate and abuts against the inclined surface, and the wedge block is configured to be movably arranged in the conveying direction to push the moving wheel to move along the inclined surface and thereby drive the positioning plate to lift and lower.

[0007] In the technical solution of the embodiment of the present application, the lifting mechanism includes a moving wheel and a wedge block. The wedge block has an inclined surface. The moving wheel is arranged on the lower side of the positioning plate and is rollingly arranged on the inclined surface. The wedge block is configured to be movably arranged in the conveying direction to push the moving wheel to move along the inclined surface and thereby drive the positioning plate to rise and fall. Compared with the use of cylinder jacking in the related art, the problem of poor stability caused by unstable air pressure is effectively improved, that is, the jacking stability is improved, thereby ensuring the position stability of the battery to be processed during the processing process, so as to improve the battery processing quality.

[0008] In some embodiments, the lifting mechanism includes a plurality of moving wheels evenly distributed on the lower side of the positioning plate and a plurality of wedge blocks cooperating with the plurality of moving wheels.

[0009] Multiple moving wheels are evenly distributed on the lower side of the positioning plate so that when lifting (or lowering), different positions of the positioning plate can be lifted, ensuring the position consistency of different positions of the positioning plate, and then ensuring the position consistency of different positions of the battery, further improving the positioning accuracy of the battery and improving the processing quality.

[0010] In some embodiments, the lifting mechanism further comprises a driving device, which drives the plurality of wedge blocks to move in the conveying direction.

[0011] Only one driving device is used to drive multiple wedge blocks to move synchronously, so only one driving device needs to be controlled. From the control logic, there is no need to synchronously control the actions of multiple driving devices, which reduces the control difficulty. Moreover, by controlling one driving device, the movement synchronization of multiple wedge blocks can be guaranteed.

[0012] In some embodiments, the lifting mechanism further comprises a connecting plate connected to the plurality of wedge blocks, and the driving device is connected to one of the plurality of wedge blocks.

[0013] A plurality of wedge blocks are connected by a connecting plate, so that as long as one of the wedge blocks moves, the other wedge blocks will also move synchronously, thereby ensuring that different positions of the positioning plate are lifted synchronously.

[0014] In some embodiments, the lifting mechanism further comprises a slider connected to the wedge block and a slide rail extending in the conveying direction, and the slider and the slide rail are slidably matched. When the slider and the slide rail are matched, the slider moves in the first direction, thereby causing the wedge block connected to the slider to move in the conveying direction, thereby ensuring the accuracy of the moving direction of the wedge block, thereby ensuring the accuracy of the moving wheel moving in the height direction, and finally ensuring the position accuracy and stability of the lifting or lowering of the positioning plate.

[0015] In some embodiments, the processing equipment further includes a moving mechanism, which is used to drive the processing device to move so as to process different positions of the battery to be processed. The processing device is moved by setting the moving mechanism to process welds at different positions. Moreover, by setting the moving mechanism to move the position of the processing device, the welds of batteries of different sizes can be processed, thereby expanding the scope of application of the battery processing equipment.

[0016] In some embodiments, the moving mechanism includes a first moving mechanism, which is used to drive the processing device to move in the height direction; and / or the moving mechanism includes a second moving mechanism, which is used to drive the processing device to move in a direction perpendicular to the conveying direction.

[0017] The first moving mechanism is used to drive the processing device to move in the height direction. By moving in the height direction, all-round processing in the extension direction of the weld can be achieved, thereby improving production efficiency. The second moving mechanism is used to drive the processing device to move in a direction perpendicular to the conveying direction so as to move to the position of another weld after completing the grinding of one weld to grind another weld. In addition, for battery boxes of different sizes, the grinding of the welds of battery boxes of different sizes can be achieved by moving the grinding mechanism in a direction perpendicular to the conveying direction, thereby expanding the scope of application of the battery processing equipment of this embodiment.

[0018] In some embodiments, the processing device includes a grinding mechanism and a coding mechanism, the grinding mechanism is used to grind the weld of the battery to be processed, and the coding mechanism is used to code the battery to be processed.

[0019] The processing device of the embodiment of the present application integrates the grinding mechanism and the coding mechanism into an integrated design, so that grinding and coding can be completed at the same station, avoiding the need for transfer, thereby reducing processing time and improving production efficiency. In addition, the integrated design eliminates the need to design a separate coding station, reduces site occupation area, and reduces equipment costs.

[0020] In some embodiments, the grinding mechanism includes a nylon brush. Grinding the weld with the nylon brush will not cause excessive damage to the weld while ensuring that the burrs on the weld are removed, thereby ensuring the processing quality.

[0049] refer to Figure 1 The battery includes a battery box 80 and a battery cell (not shown) disposed in the battery box 80. The battery box 80 includes a plurality of side panels arranged in a circumferential direction. Two adjacent side panels of the plurality of side panels are connected by welding. The weld A formed by welding may have defects such as burrs, and the battery after welding needs to be further processed by battery processing equipment.

[0050] Figure 1 The battery box 80 is exemplarily shown as a square, but is not limited to a square. The square battery box 80 includes four side plates arranged in a circumferential direction. Figure 1 In the coordinate system in , the battery box 80 includes two first side plates 81 parallel to and opposite to the first direction y and two second side plates 82 parallel to and opposite to the second direction x. The edges of the adjacent first side plates 81 and the second side plates 82 are connected by welding to form a weld A. Figure 1 It can be seen that the square battery box 80 includes four weld seams A.

[0051] After welding, the battery is transported to the processing position by the conveying mechanism, and the battery processing equipment further processes the battery at the processing position. During the research process, it was found that the position accuracy and stability of the battery during the processing process have an important impact on the processing quality of the battery. During the research process, the applicant proposed to use a lifting mechanism composed of a moving wheel and a wedge block to position the battery, thereby improving the processing quality of the battery.

[0052] Reference below Figures 2 to 7 The structure and working process of the battery processing equipment in some embodiments of the present application are described in detail.

[0053] refer to Figure 2 and Figure 3 The battery processing equipment of some embodiments of the present application includes a tray 70, a positioning mechanism 40 and a processing device. The tray 70 is used to carry the battery to be processed and the tray 70 is movably arranged in the conveying direction to reach or leave the processing position. The tray 70 has a first positioning structure. The processing device is used to process the battery to be processed. The positioning mechanism 40 is arranged below the tray 70. Figure 4 and Figure 5 , and the positioning mechanism 40 has a positioning plate 41 and a lifting mechanism 42. The positioning plate 41 has a second positioning structure. The lifting mechanism 42 is used to drive the positioning plate 41 to rise and fall. If the tray 70 reaches the processing position, the lifting mechanism 42 drives the positioning plate 41 to rise so that the second positioning structure cooperates with the first positioning structure; if the processing device completes the processing of the battery to be processed, the lifting mechanism 42 drives the positioning plate 41 to fall so that the second positioning structure is out of cooperation with the first positioning structure.

[0054] Among them, reference Figure 5 The lifting mechanism 42 includes a moving wheel 421 and a wedge block 422. The wedge block 422 has an inclined surface. The moving wheel 421 is arranged on the lower side of the positioning plate 41 and abuts on the inclined surface. The wedge block 422 is configured to be movably arranged in the conveying direction to push the moving wheel 421 to move along the inclined surface and thereby drive the positioning plate 41 to rise and fall.

[0055] exist Figures 2 to 5 In the embodiment shown, the conveying direction is the first direction y. Of course, in other embodiments not shown in the drawings, the conveying direction may also be other directions, such as the second direction x.

[0056] refer to Figure 2 ,exist Figure 2 In the illustrated embodiment, the battery processing apparatus comprises a frame 10, a positioning mechanism 40 and a processing device disposed on the frame 10. The frame 10 forms a mounting base for the positioning mechanism 40 and the processing device.

[0057] refer to Figure 3 The tray 70 is used to carry the battery to be processed. In some embodiments, the tray 70 is transported by the conveying mechanism and moves along the conveying direction (eg, the positive direction of the first direction y) to reach the processing position to process the battery to be processed or to move the battery away from the processing position after the processing is completed.

[0058] Figure 1 The positioning mechanism 40 is shown, but the tray 70 is not shown. The tray 70 is arranged above the positioning mechanism 40. When the tray 70 moves along the conveying direction under the conveying of the conveying mechanism to reach the processing position, the positioning mechanism 40 serves to stabilize the position of the tray 70 at the processing position. Figure 4 and Figure 5The positioning mechanism 40 includes a positioning plate 41 and a lifting mechanism 42 disposed at the lower side of the positioning plate 41. The positioning plate 41 has a second positioning structure (e.g., a positioning rod 412), and the tray 70 has a first positioning structure (e.g., a positioning hole). After the tray 70 reaches the processing position, the lifting mechanism 42 lifts the positioning plate 41 upward so that the second positioning structure on the positioning plate 41 cooperates with the first positioning structure on the tray 70, thereby locking the position of the tray 70 at the processing position, effectively preventing the position of the tray 70 from moving or shifting, thereby ensuring the position stability of the battery to be processed during the processing process.

[0059] In order to realize the lifting of the positioning plate 41, as Figure 5 As shown, the lifting mechanism 42 includes a moving wheel 421 and a wedge block 422. The wedge block 422 has an inclined surface. The moving wheel 421 rolls with the inclined surface. In this way, when the wedge block 422 moves along the conveying direction, the moving wheel 421 rolls along the inclined surface under the push of the inclined surface. Figure 5 In the embodiment, if the wedge block 422 moves in the reverse direction of the first direction y, the moving wheel 421 will roll upward along the inclined surface to lift the positioning plate 41. After the battery to be processed is processed, the wedge block 422 moves in the positive direction of the first direction y so that the moving wheel rolls downward along the inclined surface to lower the positioning plate 41.

[0060] In the technical solution of the embodiment of the present application, the lifting mechanism 42 includes a moving wheel 421 and a wedge block 422. The wedge block 422 has an inclined surface. The moving wheel 421 is arranged on the lower side of the positioning plate 41 and is rolled on the inclined surface. The wedge block 422 is configured to be movably arranged in the conveying direction to push the moving wheel 421 to move along the inclined surface and thereby drive the positioning plate 41 to rise and fall. Compared with the use of cylinder jacking in the related art, the problem of poor stability caused by unstable air pressure is effectively improved, that is, the jacking stability is improved, thereby ensuring the position stability of the battery to be processed during the processing process, so as to improve the battery processing quality.

[0061] In some embodiments, the lifting mechanism 42 includes a plurality of moving wheels 421 evenly distributed on the lower side of the positioning plate 41 and a plurality of wedge blocks 422 cooperating with the plurality of moving wheels 421 .

[0062] refer to Figure 5 The lifting mechanism 42 includes four moving wheels 421 evenly distributed on the lower side of the positioning plate 41. In other embodiments, the lifting mechanism 42 may also include two or more moving wheels 421. The moving wheels 421 are rotatably connected to the lower side of the positioning plate 41. Figure 5 In the illustrated embodiment, a mounting seat is provided on the lower side of the positioning plate 41 , and the moving wheel 421 is mounted on the mounting seat.

[0063] Multiple moving wheels 421 are evenly distributed on the lower side of the positioning plate 41 so that when lifting (or lowering), different positions of the positioning plate 41 can be lifted, ensuring the position consistency of different positions of the positioning plate 41, and further ensuring the position consistency of different positions of the battery, further improving the positioning accuracy of the battery and improving the processing quality.

[0064] In order to maintain the synchronization of the movement of the multiple wedge blocks 422, in some embodiments, the lifting mechanism 42 further includes a driving device 426. The driving device 426 drives the multiple wedge blocks 422 to move in the conveying direction. In other words, only one driving device 426 is used to drive the multiple wedge blocks 422 to move synchronously, so only one driving device 426 needs to be controlled. From the perspective of control logic, there is no need to synchronously control the actions of the multiple driving devices, which reduces the control difficulty. Moreover, by controlling one driving device 426, the movement synchronization of the multiple wedge blocks 422 can be ensured.

[0065] In some embodiments, the lifting mechanism 42 further includes a connecting plate 427 connected to the plurality of wedge blocks 422. The driving device 426 is connected to one of the plurality of wedge blocks 422.

[0066] The plurality of wedge blocks 422 are connected by a connecting plate 427, so that as long as one of the wedge blocks 422 moves, the other wedge blocks 422 will also move synchronously. Figure 5 In the illustrated embodiment, the drive device 426 is connected to a wedge block 422 .

[0067] In some embodiments, the lifting mechanism 42 further includes a slider 423 connected to the wedge block 422 and a slide rail 424 extending along the conveying direction. The slider 423 and the slide rail 424 are slidably matched.

[0068] like Figure 5 As shown, the slider 423 is connected to the connecting plate 427. The slide rail 424 is arranged on the bottom plate 43. The slide rail 424 extends along the conveying direction y, so that the slider 423 cooperates with the slide rail 424, and the slider 423 moves along the conveying direction, thereby making the wedge block 422 connected to the slider 423 also move along the conveying direction, ensuring the accuracy of the moving direction of the wedge block 422, thereby ensuring the accuracy of the moving wheel moving in the height direction, and finally ensuring the position accuracy and stability of the lifting or lowering of the positioning plate 41.

[0069] In some embodiments, the processing equipment further comprises a moving mechanism, which is used to drive the processing device to move so as to process different positions of the battery to be processed.

[0070] By setting a moving mechanism to move the processing device, the welds at different positions can be processed. Moreover, by setting a moving mechanism to move the position of the processing device, the welds of batteries of different sizes can be processed, thereby expanding the application range of the battery processing equipment.

[0071] In some embodiments, the moving mechanism includes a first moving mechanism 50. The first moving mechanism 50 is used to drive the processing device to move in the height direction z. By moving in the height direction z, all-round processing in the extension direction of the weld can be achieved, thereby improving production efficiency.

[0072] The moving mechanism includes a second moving mechanism 60, and the second moving mechanism 60 is used to drive the processing device to move in a direction perpendicular to the conveying direction.

[0073] The second moving mechanism 60 is used to drive the processing device to move in a direction perpendicular to the conveying direction so as to move to the position of another weld to grind the other weld after completing the grinding of one weld. In addition, for battery boxes of different sizes, the grinding of the welds of battery boxes of different sizes can be achieved by moving the grinding mechanism in a direction perpendicular to the conveying direction, thereby expanding the scope of application of the battery processing equipment of this embodiment.

[0074] In some embodiments, the processing device includes a grinding mechanism 20, which is used to grind the weld of the battery to be processed. The processing device includes a coding mechanism 30, which is used to code the battery to be processed.

[0075] The processing device of the embodiment of the present application integrates the grinding mechanism 20 and the coding mechanism 30 into an integrated design, so that grinding and coding can be completed at the same station, avoiding the need for transfer, thereby reducing processing time and improving production efficiency. In addition, the integrated design eliminates the need to design a separate coding station, reduces site occupation area, and reduces equipment costs.

[0076] In some embodiments, the grinding mechanism includes a nylon brush. Grinding the weld with the nylon brush will not cause excessive damage to the weld while ensuring that the burrs on the weld are removed, thereby ensuring the processing quality.

[0077] The present application also provides a battery production line, including a battery welding device and the above-mentioned battery processing equipment. The battery to be processed includes a battery case and a battery cell arranged in the battery case. The battery welding device is used to weld adjacent side panels of the battery case, and the battery processing equipment is used to process the welded battery case.

[0078] According to the following Figures 1 to 7 The structure of a battery processing equipment according to a specific embodiment of the present application is described in detail.

[0079] like Figure 2 As shown, the battery processing equipment of this embodiment includes a frame 10, a positioning mechanism 40 and a processing device arranged on the frame 10. The frame 10 includes a base 11, a plurality of columns 12 extending along the height direction z, and a connecting beam 13 for connecting the columns 12. The positioning mechanism 40 is arranged on the base 11. The processing device is arranged on the connecting beam 13.

[0080] like Figure 2 As shown, the processing device of this embodiment includes a grinding mechanism 20 and a coding mechanism 30. The grinding mechanism 20 is used to grind the weld of the battery to be processed. The coding mechanism 30 is used to engrave a code (such as a QR code) on the box of the battery to be processed to achieve real-time traceability of each battery.

[0081] like Figure 1 As shown, the battery box 80 is generally a square box. The square box includes four welds A. In order to further improve the processing efficiency, as shown in FIG. Figure 2 As shown, the battery processing equipment includes two processing devices arranged opposite to each other. The two processing devices are respectively arranged at two ends of the frame 10 in the first direction y. One of the two processing devices is used to grind the two welds at the first end of the battery box 80, and the other of the two processing devices is used to grind the two welds at the second end of the battery box 80.

[0082] One of the two processing devices includes a grinding mechanism 20 and a coding mechanism 30. After the grinding mechanism 20 grinds the two welds, the coding mechanism 30 engraves codes on the side plate. The other of the two processing devices includes a grinding mechanism 20, which is used to grind the two welds respectively.

[0083] like Figure 3 As shown, the tray 70 is used to carry the batteries to be processed. The tray 70 includes a limiting structure for limiting the batteries to be processed. The limiting structure includes two first limiting blocks 71 spaced apart in the first direction y and two second limiting blocks 72 spaced apart in the second direction x. The first limiting block 71 is a T-shaped block, and the second limiting block 72 is a right-angle block. When carrying the batteries to be processed, the two corners of the first end of the batteries to be processed in the first direction y are limited by the first limiting block 71 and the second limiting block 72, respectively. The two corners of the second end of the batteries to be processed in the first direction y are limited by the first limiting block 71 and the second limiting block 72, respectively.

[0084] By setting the first limit block 71 as a T-shaped block, the first limit block 71 has two limit notches respectively located on both sides, so that two batteries to be processed can be limited at the same time. In this way, the tray 70 of this embodiment can carry two batteries to be processed at the same time with a simpler structure, and the battery processing equipment of this embodiment can process two batteries to be processed at the same time, thereby improving production efficiency.

[0085] The tray 70 of this embodiment reaches the processing position or leaves the processing position under the conveyance of the conveying mechanism. The conveying mechanism can be a double-speed chain conveyor line. The tray 70 moves along the first direction y under the conveyance of the double-speed chain conveyor line. When the tray 70 moves to the processing position, the double-speed chain conveyor line stops conveying so that the tray 70 stops at the processing position. After the processing of the battery to be processed is completed, the double-speed chain conveyor line is started again to drive the tray 70 to continue to move forward along the first direction y.

[0086] The positioning mechanism 40 is disposed below the tray 70. When the tray 70 reaches the processing position, the positioning plate 41 of the positioning mechanism 40 is lifted upward under the drive of the lifting mechanism 42 to realize the positioning of the tray 70.

[0087] like Figure 4 and Figure 5 As shown, the positioning mechanism 40 includes a positioning plate 41, a bottom plate 43, and a lifting mechanism 42 disposed between the positioning plate 41 and the bottom plate 43. The positioning plate 41 and the bottom plate 43 are spaced apart in the height direction z. The bottom plate 43 is fixedly connected to the frame 10. The lifting mechanism 42 is used to lift the positioning plate 41. Figure 4 As shown, the upper surface of the positioning plate 41 is provided with uniformly distributed support pads 48. The positioning plate 41 also has a positioning rod 412. The tray 70 has a positioning hole. When the tray 70 moves to the processing position, the positioning plate 41 is driven by the lifting mechanism 42 to lift upward so that the positioning rod 412 is inserted into the positioning hole, thereby locking the position of the tray 70 to prevent movement.

[0088] like Figure 4 As shown, the positioning plate 41 has two positioning rods 412, and the two positioning rods 412 are arranged on the diagonal lines of the positioning plate 41. The position of the tray 70 is locked by the two positioning rods 412.

[0089] like Figure 5As shown, the lifting mechanism 42 includes a plurality of moving wheels 421, a plurality of wedge blocks 422, a slider 423, a slide rail 424, a driving device 426 and a connecting plate 427. Among them, the plurality of moving wheels 421 are rotatably connected to the lower side of the positioning plate 41. Each moving wheel 421 abuts against the inclined surface of the corresponding wedge block 422. The plurality of wedge blocks 422 are connected to each other through the connecting plate 427. The driving device 426 is connected to one of the wedge blocks 422 and drives the other wedge blocks 422 to move synchronously through the connecting plate 427. During the movement of the wedge block 422, different positions of the inclined surface of the wedge block 422 abut against the moving wheel 421, such as Figure 5 As shown, when the wedge block 422 moves in the reverse direction along the first direction y, the contact position of the moving wheel 421 will continuously move upward, thereby causing the positioning plate 41 to move upward in the height direction to complete the lifting, and the positioning rod 412 on the positioning plate 41 is inserted into the positioning hole of the tray 70. When the wedge block 422 moves in the forward direction along the first direction y, the contact position of the moving wheel 421 will continuously move downward, thereby causing the positioning plate 41 to descend, and the positioning rod 412 is disengaged from the positioning hole of the tray 70.

[0090] like Figure 6 As shown, the grinding mechanism 20 includes a nylon brush 21, a grinding motor 24 and a transmission mechanism 23, wherein the nylon brush 21 is rotatably arranged around its axis to grind the weld. The grinding motor 24 is connected to the nylon brush 21 through the transmission mechanism 23 to drive the nylon brush 21 to rotate. Figure 6 It can be seen that the driving shaft of the grinding motor 24 is not colinear with the driving shaft of the nylon brush 21, so the power needs to be transmitted through the transmission mechanism 23. The transmission mechanism 23 can be a belt transmission mechanism or a chain transmission mechanism.

[0091] Since the weld of the battery box extends in the height direction z, in order to achieve grinding over the entire length of the weld, Figure 6 As shown, the battery processing equipment of this embodiment includes a first moving mechanism 50. The first moving mechanism 50 drives the processing device to move in the height direction z.

[0092] The two welds at the same end of the battery box are spaced apart in the second direction x, such as Figure 1 As shown, the battery processing equipment further includes a second moving mechanism 60. The second moving mechanism 60 is used to drive the processing device to move in the second direction x so as to move to the position of another weld to grind the other weld after completing the grinding of one weld. In addition, for battery boxes of different sizes, the grinding of welds of battery boxes of different sizes can be achieved by moving the grinding mechanism in the second direction x, thereby expanding the scope of application of the battery processing equipment of this embodiment.

[0093] like Figure 7As shown, the coding mechanism 30 includes a laser head 31 and a dust extraction hood 32. The coding mechanism 30 moves in a full range driven by the first moving mechanism 50 and the second moving mechanism 60 to achieve coding of the battery.

[0094] The working process of the battery processing equipment of this embodiment is as follows:

[0095] First, the conveying mechanism conveys the tray to the processing position. Then the driving device is controlled to drive the positioning plate to rise so that the positioning column is inserted into the positioning hole to position the tray. Then the coding mechanism moves to the side plate of the battery box to engrave the code. After the coding is completed, the grinding mechanism moves to the weld position to grind the weld. After the grinding is completed, the driving device is controlled to drive the positioning plate to descend so that the positioning column is separated from the positioning hole, and then the conveying mechanism is controlled to transport the tray away from the processing position.

[0096] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
