Description

Technical Field

[0001] The present invention relates to the technical field of battery casing processing, and in particular to a battery casing processing device for a new energy vehicle. Background Art

[0002] The battery case is an external container that protects the internal components of the battery. It is essential to ensure the safety, stability and service life of the battery. The battery case is usually box-shaped and is assembled and welded by a U-shaped part and an L-shaped part. Both the U-shaped part and the L-shaped part are formed by bending plates. At present, there are still the following problems when welding the two parts of the welded parts: the splicing accuracy between the U-shaped welded parts and the L-shaped welded parts will directly affect the inner diameter dimensional accuracy of the battery case. At present, welders only assemble through welding platforms and fixtures. Welders manually control the welding platform and fixtures to fix and combine the U-shaped welded parts and the L-shaped welded parts, and the assembly efficiency is low; secondly, in the splicing of the L-shaped welded parts and the U-shaped welded parts, the welding accuracy is not good. During the process, the positioning of the two side edges of the L-shaped welded part will hinder the vertical seam, making it difficult for the welding equipment to continuously complete the welding of the entire seam, and the welding efficiency is low; furthermore, the two parallel sections of the 凵-shaped welded part and the horizontal section of the L-shaped welded part are more likely to bend inward during the process of moving to the welding platform or during manual splicing, but the welding platform is not provided with a mechanism for straightening, and the inward bending will make it difficult for the ends of the 凵-shaped welded part and the L-shaped welded part to fully contact, which directly reduces the quality of the battery shell welding.

[0015] The beneficial effects of the present invention are as follows: 1. The linkage cooperation of the outer clamping component 1 and the inner straightening component 1 of the present invention simultaneously performs limited external support straightening on the two horizontal sections of the C-shaped tailor-welded part, and the two parallel sections and the middle section of the C-shaped tailor-welded part are kept vertical. The outer clamping component 1 and the positioning component 1 that are in contact with the C-shaped tailor-welded part are connected and locked by the positioning component 1, thereby improving the firmness between the outer clamping component 1 and the inner straightening component 1. At this time, the outer clamping component 1 and the inner straightening component 1 play the role of clamping, fixing and keeping straight in the future, which is beneficial to the accurate alignment of the C-shaped tailor-welded part and the L-shaped tailor-welded part, and improving the quality of the seam welding.

[0016] 2. The present invention limits and straightens the horizontal section of the L-shaped welded part through the cooperation of the outer clamping component 2, the inner correction component 2 and the front and rear alignment components, so that the horizontal section and the vertical section of the L-shaped welded part remain vertical, ensuring that the subsequent L-shaped welded part and the 凵-shaped welded part are aligned and spliced front to back. When the L-shaped welded part and the 凵-shaped welded part are butt-jointed, the front and rear alignment components are separated from the front and rear sides of the L-shaped welded part to avoid affecting the welding of the L-shaped welded part and the 凵-shaped welded part.

[0017] 3. The present invention drives the first fixing mechanism and the second fixing mechanism to approach each other through a single driving source to achieve clamping, correction and alignment splicing of the U-shaped welded parts and the L-shaped welded parts, thereby improving the efficiency of splicing welding of the U-shaped welded parts and the L-shaped welded parts, and maintaining the mutual locking between the first fixing mechanism and the second fixing mechanism during the welding process, avoiding the displacement of the U-shaped welded parts and the L-shaped welded parts during the welding process, which is beneficial to improving the processing quality of the battery shell.

Detailed implementation manners

[0032] In order to make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0033] Please refer to Figure 1 and Figure 2, A processing device for a new energy vehicle battery housing, including a processing table 1. On the top of the processing table 1, a first fixing mechanism 2 and a second fixing mechanism 3 are installed and distributed left and right. A moving mechanism 4 for driving the first fixing mechanism 2 and the second fixing mechanism 3 to move towards each other and a multi-dimensional welding machine 6 for welding the U-shaped welded parts and L-shaped welded parts are installed on the processing table 1. A locking mechanism 5 for locking the two is installed between the first fixing mechanism 2 and the second fixing mechanism 3. It should be noted that the multi-dimensional welding machine 6 is a prior art. The welding head in the multi-dimensional welding machine 6 can move in the X-axis, Y-axis, and Z-axis. At the same time, the horizontal angle and vertical angle of the welding head in the multi-dimensional welding machine 6 can both be adjusted by 360 degrees of rotation to meet the multi-dimensional welding requirements of the battery housing of the present invention.

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , The first fixing mechanism 2 includes an outer clamping component one 21 that is slidably installed left and right on the processing table 1 and is used for externally clamping and limiting the U-shaped welded parts, and an inner correction component one 22 that is arranged inside the outer clamping component one 21 to expand and correct the U-shaped welded parts. A positioning component one 23 for mutually locking the outer clamping component one 21 and the inner correction component one 22 is installed on the top of the processing table 1. A positioning component two 24 is installed on the inner correction component one 22. An unlocking component 25 for unlocking the positioning component one 23 and the positioning component two 24 simultaneously is installed on the processing table 1.

[0035] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , The second fixing mechanism 3 includes an outer clamping component two 31 that is slidably installed left and right on the processing table 1 and is used for externally pressing and limiting the L-shaped welded parts. An inner correction component two 32 for expanding and correcting the L-shaped welded parts is installed inside the outer clamping component two 31. A front and rear alignment component 33 for positioning the L-shaped welded parts front and back in the middle is installed on the top of the processing table 1. An elastic telescopic rod two 34 is installed between the inner correction component one 22 and the inner correction component two 32.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3, the outer clamping assembly 21 includes an outer center plate 211 slidably mounted left and right on the top of the processing table 1. Outer clamping plates 212 perpendicular to the outer center plate 211 are slidably mounted front and rear at both ends of the outer center plate 211. A pushing member 213 for driving the outer center plate 211 to move left and right is mounted on the top of the processing table 1. A guiding member 214 for guiding the outer clamping plates 212 to clamp inwardly through the rightward movement of the outer center plate 211 is mounted on the processing table 1. The pushing member 213 includes a pushing plate 2131 slidably mounted left and right on the top of the processing table 1. Symmetrically distributed guiding rods 2132 are fixedly connected to the left side of the outer center plate 211. The left ends of the guiding rods 2132 slidably penetrate to the left side of the pushing plate 2131 and are fixedly connected with stoppers. A compression spring 2133 sleeved on the outer portion of the guiding rod 2132 is fixedly connected between the pushing plate 2131 and the outer center plate 211. The guiding member 214 includes guiding inclined grooves 2141 symmetrically formed front and rear on the top of the processing table 1 and inclined toward the center of the processing table 1 at the right end. A slider 2142 is fixedly connected to the bottom of the outer clamping plate 212. The slider 2142 is slidably mounted inside the corresponding guiding inclined groove 2141.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the inner correction assembly 22 includes an inner center plate 221 fixedly connected to the top of the processing table 1 and located on the right side of the outer center plate 211. Inner clamping plates 222 located inside the outer clamping plates 212 are rotatably connected to both ends of the inner center plate 221 through shaft rods. A rotating member 223 for driving the corresponding inner clamping plates 222 to rotate is mounted on the bottom of the inner center plate 221. An angle limiting member 224 corresponding to the inner clamping plates 222 and limiting the rotation angle of the inner clamping plates 222 is mounted on the right side of the inner center plate 221. The rotating member 223 includes a rack 2231 fixedly connected to the bottom of the inner center plate 221. A gear 2232 is coaxially fixedly connected to the bottom of the shaft rod. The rack 2231 is meshed with the inner side of the gear 2232.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, when fixing and correcting the U-shaped welded parts, the U-shaped welded parts are placed with the opening facing to the right. The horizontal longitudinal section of the U-shaped welded parts is placed between the outer center plate 211 and the inner center plate 221. The two parallel sections of the U-shaped welded parts are respectively located between the corresponding outer clamping plates 212 and the inner clamping plates 222. Then, the moving mechanism 4 drives the pushing plate 2131 to move to the right. The pushing plate 2131 pushes the outer center plate 211 to move to the right by compressing the compression spring 2133. During the process of the outer center plate 211 moving to the right, the guiding inclined groove 2141 will guide the slider 2142, so that the slider 2142 drives the outer clamping plate 212 to move towards the center of the processing table 1. When the outer center plate 211 is pressed against the left side of the horizontal longitudinal section of the U-shaped welded parts, the outer clamping plate 212 just presses against the outside of the corresponding parallel section of the U-shaped welded parts.

[0039] At the same time, when the outer center plate 211 moves to the right, the outer center plate 211 will drive the rack 2231 to move to the right. The rack 2231 will engage with the inner side of the gear 2232. The corresponding gear 2232 is driven to rotate by the rack 2231, and then the inner clamping plate 222 is driven by the gear 2232 to deflect outwards, so that the inner clamping plate 222 straightens the two parallel sections of the U-shaped welded parts from the inside to the outside. When the inner clamping plate 222 rotates to be perpendicular to the inner center plate 221, the outer clamping plate 212 just presses against the outside of the U-shaped welded parts, thereby correcting the two parallel sections of the U-shaped welded parts to be perpendicular to the horizontal section, which is convenient for subsequent assembly and welding.

[0040] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , the second outer clamping assembly 31 includes a movable seat 311 slidably mounted on the top of the processing table 1 from left to right. A reverse L-shaped outer support frame 312 is fixedly mounted on the top of the movable seat 311. A first limiting plate 313 is slidably mounted on the top of the outer support frame 312 from left to right. A left and right moving member 314 for driving the first limiting plate 313 to move left and right is mounted on the horizontal section of the outer support frame 312. The left and right moving member 314 includes a first chute 3141 opened on the top of the horizontal section of the outer support frame 312. A threaded rod 3142 is rotatably mounted inside the first chute 3141. A first sliding seat 3143 is threadedly connected to the outside of the threaded rod 3142. The first sliding seat 3143 is slidably mounted inside the first chute 3141. The first limiting plate 313 is fixedly mounted on the top of the first sliding seat 3143. The right end of the threaded rod 3142 rotatably penetrates to the right side of the outer support frame 312 and is fixedly connected with a turning handle 3144. A limiting pin 3145 that is in plug-in fit with the outer support frame 312 is threadedly connected to the turning handle 3144.

[0041] In the initial state, the first limiting plate 313 is located at the left end of the horizontal section of the outer support frame 312. The first limiting plate 313 functions to resist and limit the horizontal section of the L-shaped welded part. After the L-shaped welded part and the U-shaped welded part are welded, the limit pin 3145 is loosened to release the limit on the rotary handle 3144, and then the rotary handle 3144 is rotated to drive the threaded rod 3142 to rotate. The threaded rod 3142 is used to drive the first sliding seat 3143 to move to the right, and the first sliding seat 3143 drives the first limiting plate 313 to move to the right, so that the first limiting plate 313 no longer blocks the top of the battery housing, facilitating the upward removal of the welded battery housing.

[0042] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 , the second inner correction component 32 includes an inner support frame 321 that is slidably installed left and right on the top of the movable seat 311 and is located on the left side of the outer support frame 312. The inner support frame 321 is L-shaped, and guide blocks 3211 are fixedly connected to both the front and rear sides of the horizontal section. Guide grooves 2221 that are slidably inserted and matched with the corresponding guide blocks 3211 are opened on the opposite sides of the front and rear inner clamping plates 222. A top push plate 322 that is located below the first limiting plate 313 is hinged to the top of the inner support frame 321. An angle limiting component two 323 for limiting the rotation angle of the top push plate 322 is fixedly installed on the left side of the vertical section of the inner support frame 321. A top push component 324 is installed at the left end of the top push plate 322. It should be noted that rollers are rotatably installed on the sides of the inner center plate 221, the inner clamping plates 222, and the vertical section of the inner support frame 321 that are in contact with the corresponding U-shaped welded part and L-shaped welded part to reduce the friction with the U-shaped welded part and L-shaped welded part and facilitate the upward removal of the welded battery housing.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , when fixing and correcting the L-shaped welded part, place the vertical section of the L-shaped welded part between the vertical sections of the inner support frame 321 and the outer support frame 312, and place the horizontal section of the L-shaped welded part between the top push plate 322 and the first limiting plate 313. Use the moving mechanism 4 to drive the movable seat 311 to move to the left. The movable seat 311 drives the outer support frame 312 and the first limiting plate 313 to move to the left together. At this time, the inner support frame 321 remains stationary under the support of the second elastic telescopic rod 34, and the vertical sections of the inner support frame 321 and the outer support frame 312 are used to clamp and fix the vertical section of the L-shaped welded part.

[0044] Please refer to Figure 1 , Figure 4 and Figure 7, the angle limiting member two 323 includes fixing plates 3231 fixedly connected to the left side of the vertical section of the inner support frame 321 and symmetrically distributed front and back. The bottom of the pushing plate 322 is fixedly connected with a movable plate two 3232 located between the two front and back fixing plates 3231. The fixing plates 3231 are provided with arc-shaped limiting grooves 3233. The front and back sides of the movable plate two 3232 are fixedly connected with limiting blocks 3234 that are slidably engaged with the corresponding arc-shaped limiting grooves 3233. The angle limiting member one 224 has the same structure as the angle limiting member two 323.

[0045] When the pushing plate 322 deflects upward, the pushing plate 322 will drive the movable plate two 3232 to rotate upward together. At this time, the movable plate two 3232 will drive the limiting block 3234 to slide upward along the arc-shaped limiting groove 3233. When the pushing plate 322 rotates to the horizontal state, the limiting block 3234 just slides to the upper end of the arc-shaped limiting groove 3233. The rotation angle of the limiting block 3234, the movable plate two 3232 and the pushing plate 322 is limited by the arc-shaped limiting groove 3233, avoiding excessive rotation of the pushing plate 322 and ensuring that the pushing plate 322 just corrects the horizontal section of the L-shaped welded part to be perpendicular to its vertical section.

[0046] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 , the pushing member 324 includes symmetric grooves (front and back) opened at the bottom left end of the pushing plate 322, and a rotating shaft 3241 fixedly connected in the grooves. Symmetrically distributed rollers 3242 are rotatably installed on the rotating shaft 3241. A positioning block 3243 is fixedly connected to the middle of the rotating shaft 3241. The bottom end of the positioning block 3243 extends below the pushing plate 322. A sloping plate 3244 is fixedly connected to the right side of the inner clamping plate 222. The left side of the top of the sloping plate 3244 is flush with the top of the inner clamping plate 222, and the right side slopes downward. A positioning groove 3245 that is slidably engaged with the positioning block 3243 is jointly opened on the top of the sloping plate 3244 and the inner clamping plate 222. A through groove corresponding to the sloping plate 3244 is opened on the inner support frame 321.

[0047] After the outer support frame 312 and the inner support frame 321 clamp and fix the vertical section of the L-shaped welded part, the moving mechanism 4 continues to drive the movable seat 311 to move leftward. The outer support frame 312 will push the L-shaped welded part and the inner support frame 321 to move leftward together. At this time, the second elastic telescopic rod 34 will be compressed. At this time, the inner clamping plate 222 has rotated to a state parallel to the inner center plate 221, that is, the correction of the U-shaped welded part is completed, and the outer clamping plate 212 and the inner clamping plate 222 are respectively clamped on the inner and outer sides of the U-shaped welded part. When the inner support frame 321 approaches the inner clamping plate 222, the roller 3242 contacts the top of the inclined plate 3244 and moves along the inclined plate 3244. The inclined plate 3244 is used to support and guide the top push plate 322, so that the top push plate 322 rotates upward to a horizontal state. After the top push plate 322 is horizontal and continues to slide, the roller 3242 can roll along the top of the inner clamping plate 222, reducing the friction between the top push plate 322 and the inner clamping plate 222. At the same time, the positioning block 3243 will move along the positioning groove 3245, and the positioning groove 3245 is used to guide and limit the positioning block 3243, ensuring that the top push plate 322 and the inner clamping plate 222 are accurately spliced together, improving the accuracy of the splicing of the L-shaped welded part and the U-shaped welded part.

[0048] During the process of the top push plate 322 moving to the top of the inner clamping plate 222, the horizontal section of the inner support frame 321 moves between the front and rear inner clamping plates 222. At this time, the guide block 3211 is inserted into the inside of the guide groove 2221 and slides leftward along the guide groove 2221. The horizontal section of the inner support frame 321 is used to limit and support the front and rear inner clamping plates 222, preventing the inner clamping plate 222 from rotating inward, and improving the firmness of the inner clamping plate 222 to expand and support the two parallel sections of the U-shaped welded part.

[0049] Please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 11 and Figure 12 , the front and rear alignment assembly 33 includes baffles 331 fixedly connected to the top of the processing table 1 and symmetrically distributed about the movable seat 311 in the front and rear. Both the left and right ends of the baffle 331 are slidably installed through the front and rear with movable rods 332. A third return spring 333 sleeved outside the movable rod 332 is fixedly connected between the end of the movable rod 332 away from the movable seat 311 and the baffle 331. The left and right movable rods 332 penetrate to the inside of the movable seat 311 and are jointly fixedly connected with an alignment plate 334. A guide groove 335 for guiding the alignment plate 334 to move toward the movable seat 311 is formed at the bottom of the alignment plate 334. The guide groove 335 is composed of horizontal sections arranged in a staggered manner in the front and rear and inclined sections connecting between the horizontal sections. An elastic telescopic rod 336 slidably engaged with the guide groove 335 is fixedly connected to the top of the movable seat 311. The top end of the telescopic section of the elastic telescopic rod 336 is provided with an inclined surface inclined to the lower right side.

[0050] When the movable seat 311 drives the outer support frame 312 to move leftward to clamp the vertical section of the L-shaped welded part, the movable seat 311 will drive the first elastic telescopic rod 336 to move leftward. Before the vertical sections of the outer support frame 312 and the inner support frame 321 clamp the vertical section of the L-shaped welded part, the first elastic telescopic rod 336 will first enter the guiding groove 335 and move leftward along the guiding groove 335. By using the cooperation of the first elastic telescopic rod 336 and the guiding groove 335, the alignment plate 334 and the movable rod 332 are driven to move towards the center of the processing table 1. At this time, the third return spring 333 will be compressed, and the alignment plate 334 is used to synchronously center and clamp the front and rear sides of the L-shaped welded part to ensure that the front and rear sides of the L-shaped welded part are aligned with those of the U-shaped welded part. After the front and rear centering of the L-shaped welded part, the vertical sections of the outer support frame 312 and the inner support frame 321 then clamp the vertical section of the L-shaped welded part.

[0051] After the vertical sections of the outer support frame 312 and the inner support frame 321 clamp the vertical section of the L-shaped welded part, as the movable seat 311 moves leftward, the first elastic telescopic rod 336 moves out from the left end of the guiding groove 335. At this time, the resilience of the third return spring 333 is used to push the alignment plate 334 to move and reset in the direction away from the center of the processing table 1. The alignment plate 334 is separated from the L-shaped welded part and no longer clamps the front and rear sides of the L-shaped welded part, avoiding blocking the subsequent welding of the L-shaped welded part and the U-shaped welded part.

[0052] When the movable seat 311 drives the first elastic telescopic rod 336 to move rightward and reset, the inclined surface on the telescopic section of the first elastic telescopic rod 336 will contact the bottom of the alignment plate 334, and then under the pushing of the alignment plate 334, the telescopic section of the first elastic telescopic rod 336 contracts downward, so that the first elastic telescopic rod 336 moves from below the alignment plate 334 to the right side of the alignment plate 334.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 13 As shown in

[0054] Drive the bidirectional lead screw 42 to rotate through the drive motor 44, so that the second sliding seats 43 at both left and right ends move towards each other. The second sliding seat 43 on the left drives the pushing plate 2131 to move to the right, and the second sliding seat 43 on the right drives the movable seat 311 to move to the left. When the outer center plate 211, the outer clamping plate 212, and the inner clamping plate 222 complete the external clamping and straightening of the U-shaped welded assembly, the vertical sections of the inner support frame 321 and the outer support frame 312 synchronously complete the clamping of the vertical section of the L-shaped welded assembly. After that, the second sliding seats 43 on both left and right sides continue to drive the pushing plate 2131 and the movable seat 311 to move towards each other. At this time, the compression spring 2133 and the second elastic telescopic rod 34 will be compressed until the L-shaped welded assembly and the U-shaped welded assembly are joined together. At this time, the left end of the horizontal section of the inner support frame 321 abuts against the right end of the inner center plate 221.

[0055] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the first positioning component 23 includes a plurality of hollow shells 231 fixedly installed on the processing table 1 and paired and cooperated. The inner center plate 221 is located between the corresponding and paired hollow shells 231. Paired and cooperated hollow shells 231 are arranged between the outer clamping plate 212 and the corresponding inner clamping plate 222. A wedge-shaped block 232 is slidably installed up and down at the top of the hollow shell 231. The bottom of the wedge-shaped block 232 penetrates into the interior of the hollow shell 231 and is fixedly connected with a retaining piece 233. The retaining piece 233 is slidably installed up and down inside the hollow shell 231. A first return spring 234 is fixedly connected between the bottom of the retaining piece 233 and the inner wall of the hollow shell 231. The second positioning component 24 has the same structure as the first positioning component 23. The hollow shell 231 in the second positioning component 24 is fixedly installed at the top on the right side of the inner center plate 221. The bottom of the outer center plate 211, the outer clamping plate 212, the inner clamping plate 222, and the inner support frame 321 are all provided with a first clamping groove that cooperates with the corresponding wedge-shaped block 232. The bottom of the top pushing plate 322 is provided with a second clamping groove that cooperates with the wedge-shaped block 232 in the second positioning component 24.

[0056] When the outer center plate 211 presses the U-shaped welded part against the left side of the inner center plate 221, the outer center plate 211 moves above the positioning component 23 on the left side of the inner center plate 221. The resilience of the first return spring 234 is used to push the retaining piece 233 and the wedge-shaped block 232 upward, so that the wedge-shaped block 232 is clamped into the corresponding first card slot at the bottom of the outer center plate 211, realizing the locking of the outer center plate 211, preventing the outer center plate 211 from loosening, and improving the firmness between the outer center plate 211 and the inner center plate 221. Similarly, when the outer clamping plate 212 and the inner clamping plate 222 clamp the inner and outer sides of the two parallel segments of the U-shaped welded part, the outer clamping plate 212 and the inner clamping plate 222 move onto the positioning component 23 located between them. The positioning component 23 is used to lock the outer clamping plate 212 and the inner clamping plate 222 on the inner and outer sides of the U-shaped welded part, improving the firmness of the outer center plate 211 and the inner clamping plate 222 in clamping and fixing the two horizontal segments of the U-shaped welded part.

[0057] When the L-shaped welded part and the U-shaped welded part are joined together, the left end of the horizontal section of the inner support frame 321 abuts against the right end of the inner center plate 221. The left end of the top push plate 322 presses against the positioning component 24 and is locked by the positioning component 24. At this time, the positioning component 23 on the right side of the inner center plate 221 locks the left end of the inner support frame 321, preventing the inner support frame 321 from separating from the inner center plate 221. The wedge-shaped block 232 in the positioning component 24 is clamped into the corresponding second card slot at the bottom of the top push plate 322 to lock the top push plate 322, preventing the top push plate 322 from separating from the inner center plate 221, improving the tightness of the connection between the inner support frame 321, the top push plate 322 and the inner center plate 221, and further improving the tightness of the joining of the U-shaped welded part and the L-shaped welded part.

[0058] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the unlocking component 25 includes a movable plate 251 slidably installed up and down inside the processing table 1. A second return spring 252 is fixedly connected between the bottom of the movable plate 251 and the inner wall of the processing table 1. The bottom of the movable plate 251 is fixedly connected with a pull rod 253 located below the processing table 1 through a short rod. The short rod movably penetrates the processing table 1. The top of the movable plate 251 is fixedly connected with a number of linkage rods 254 corresponding one by one to the paired hollow shells 231 in the positioning component 23. The inner center plate 221 and the processing table 1 are respectively slidably connected with the corresponding linkage rods 254. Side rods 255 are fixedly connected to the lower ends of the linkage rods 254 corresponding to the positions of the hollow shells 231. Side rods 255 are also fixedly connected to the upper ends of the linkage rods 254 on the inner center plate 221 corresponding to the hollow shells 231 in the positioning component 24. The side rods 255 are slidably connected with the corresponding hollow shells 231 up and down and press against the upper ends of the corresponding retaining pieces 233.

[0059] After the welding of the U-shaped welded parts and the L-shaped welded parts is completed, when unlocking the positioning component 1-23, push the pull rod 253 downward. Use the pull rod 253 to drive the movable plate 1-251 downward. The movable plate 1-251 drives the linkage rod 254 and the side rod 255 downward. At this time, the return spring 2-252 will be compressed. Use the side rod 255 to push the retaining piece 233 downward, so that the wedge block 232 retracts into the hollow housing 231, unlocking the wedge block 232 from locking the outer center plate 211, the outer clamping plate 212, the inner clamping plate 222 and the inner support frame 321. Similarly, when the linkage rod 254 and the side rod 255 move downward, the side rod 255 corresponding to the positioning component 2-24 unlocks the positioning component 2-24 from locking the top plate 322.

[0060] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 9 and Figure 10 As shown in, the interlocking mechanism 5 includes a plug rod assembly 51 and a lock post 52. The plug rod assembly 51 includes a mounting seat 511 with a U-shaped structure, and a plug rod 512 rotatably connected to the mounting seat 511 through a rotating rod. The opening of the mounting seat 511 faces the lock post 52. A torsion spring 513 is connected between the rotating rod and the plug rod 512. A partition plate 1 for restricting the rotation angle of the plug rod 512 is fixedly connected between the two parallel sections of the mounting seat 511. Mounting seats 511 are fixedly installed at the right end of the outer clamping plate 212 and the left end of the limiting plate 1-313. Among them, the partition plate corresponding to the front outer clamping plate 212 restricts the corresponding plug rod 512 from rotating downward, the partition plate corresponding to the rear outer clamping plate 212 restricts the corresponding plug rod 512 from rotating upward, and the partition plate corresponding to the limiting plate 1-313 restricts the corresponding plug rod 512 from rotating forward. A retaining groove matching the corresponding plug rod 512 is formed on the lock post 52. Lock posts 52 corresponding to the mounting seats 511 one by one are fixedly installed on the front and rear sides of the outer support frame 312 and the top of the outer center plate 211. The number of mounting seats 511 at the right end of the outer clamping plate 212 and the left end of the limiting plate 1-313 is at least two.

[0061] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 9 and Figure 10, when the U-shaped welded part and the L-shaped welded part are joined together, the outer clamping plate 212 and the first limiting plate 313 drive the corresponding insertion rods 512 to insert into the corresponding retaining grooves, and the retaining grooves are used to block and limit the insertion rods 512. Through the cooperation of the outer clamping plate 212, the inner clamping plate 222 with the corresponding insertion rods 512 and the retaining grooves, and through the cooperation of the first limiting plate 313, the pushing plate 322 with the corresponding insertion rods 512 and the retaining grooves, the splicing seam between the U-shaped welded part and the L-shaped welded part is limited front and back.

[0062] During the welding process, the welding head of the multi-dimensional welding machine 6 moves and welds one by one along the splicing seam between the U-shaped welded part and the L-shaped welded part from front to back. The welding head first moves from bottom to top, then from front to back, and then from top to bottom. Taking the welding head moving from bottom to top as an example, when the welding head moves to the insertion rod 512, the non-working section of the welding head is used to push the insertion rod 512 to rotate upward (refer to the appendix Figure 9 ), the end of the insertion rod 512 is separated from the corresponding retaining groove, avoiding the insertion rod 512 from blocking the movement of the welding head. At the same time, since there are no less than two insertion rod assemblies 51 installed on each outer clamping plate 212 and the first limiting plate 313, when one insertion rod assembly 51 is unlocked, another insertion rod assembly 51 still remains connected, ensuring that the splicing seam between the U-shaped welded part and the L-shaped welded part is limited front and back.

[0063] When the welding head moves to the other side of the insertion rod 512, due to the loss of the pushing force of the welding head, the resilience of the torsion spring 513 is used to push the insertion rod 512 to rotate back. The insertion rod 512 rotates back to the horizontal state under the limitation of the corresponding partition plate, and the insertion rod 512 is re-inserted into the retaining groove for limiting.

[0064] Please refer to Figures 1 - 13, after welding is completed, the multi-dimensional welding machine 6 is moved away from the top of the battery case. Then, the left and right moving component 314 drives the first limiting plate 313 to move to the right, exposing the top of the battery case. After that, the battery case is taken out upward. Then, the pull rod 253 is pressed downward to release the locking of the first positioning component 23. Then, the driving motor 44 drives the bidirectional lead screw 42 to rotate reversely, causing the two second sliding seats 43 on the left and right to move away from each other. Then, the second sliding seats 43 drive the pushing plate 2131 and the movable seat 311 to move away from each other. The movable seat 311 will first drive the outer support frame 312 and the inner support frame 321 to move to the right and separate from the outer clamping plate 212 and the inner clamping plate 222. When the top push plate 322 separates from the inner clamping plate 222, the top push plate 322 deflects towards each other under the action of its own gravity. Then, the movable seat 311 continues to move to the right. When the second elastic telescopic rod 34 returns to its original length, the inner support frame 321 no longer moves to the right. At this time, the movable seat 311 drives the outer support frame 312 to move to the right, and relative sliding occurs between the inner support frame 321 and the movable seat 311, expanding the distance between the outer support frame 312 and the inner support frame 321 to facilitate the subsequent placement of the L-shaped welded part until the right second sliding seat 43 moves to the right end of the right second chute 41 and stops moving.

[0065] When the inner support frame 321 completely moves to the right of the inner clamping plate 222, the pushing plate 2131 drives the compression spring 2133 to return to its original state. Then, the pushing plate 2131 continues to move to the left and drives the outer center plate 211 to move to the left through the compression spring 2133. During the process of the outer center plate 211 moving to the left, the guide chute 2141 guides the slider 2142 and the outer clamping plate 212 to move away from the center of the processing table 1, expanding the distance between the outer clamping plate 212 and the inner center plate 221 to facilitate the subsequent placement of the U-shaped welded part. When the outer center plate 211 moves away from the inner center plate 221, the outer center plate 211 drives the rack 2231 to move to the left. Then, the rack 2231 drives the gear 2232 to rotate reversely, causing the inner clamping plate 222 to deflect and reset towards the center of the processing table 1 until the left second sliding seat 43 moves to the left end of the left second chute 41 and stops moving.
