The holding plates are rotatably connected to the clamping blocks, and at the same time, the setting of the limiting grooves allows the two holding plates to rotate only outwards, and a resistance sheet is slidably provided on the inner side of the clamping block. When the resistance sheet When the first spring is extended, the current holding plate is prevented from rotating, thereby ensuring the clamping effect of the battery pack between the holding plates.

The sliding seat is rotatably connected to the mounting arm through the rotating shaft. When in use, in order to facilitate the user to perform welding operations, when the holding plate on one side is rotated to the top side, the end of the inner sliding piece arranged at the other end thereof slides into the positioning groove on the side of the mounting arm. At this time, under the action of the first spring, the corresponding contact piece retracts, and the user can now rotate the holding plate on the top side to a vertical state and expose the battery pack. The top side of the battery pack is exposed to facilitate welding operations, while the holding plate on the other side remains horizontal under the interference effect of the corresponding interference piece to support the battery pack. After completing the welding work on the front side, the holding plate on the top side is rotated to a horizontal state, and then the battery pack and the sliding seat are rotated 180 degrees as a whole. In order to make the holding plate on the bottom side more stable, the user can rotate the locking rod on the bottom side of the mounting arm when the battery pack is rotated to a horizontal state, so that the end of the locking rod passes through the rotating shaft, thereby preventing the rotating shaft from continuing to rotate, which is convenient for welding the electrodes and connecting pieces on both sides of the battery pack and improves work efficiency. In order to avoid the battery pack being rotated, the electric In case the battery pack slides sideways, a side slider is provided on both sides of the holding plate.

When moving the side sliders, the user needs to press the engaging blocks on the sides of the side sliders at the same time to release the engaging state between the bottom end of the engaging block and the sawtooth groove. After the side slider slides to the specified position, the engaging block is released. At this time, the two sides of the battery pack can be blocked under the engaging action between the engaging blocks and the sawtooth grooves to prevent the battery pack from sliding sideways when flipped, and the overall stability of the battery pack during welding is improved, which is convenient to use.

[0017] (2) In a battery packaging connecting plate welding device described in the present invention, a positioning structure is provided on the top of the operating table; the positioning structure can be used to fix the holding plate on the top side, which is convenient for welding operation, that is: when the battery pack is in a horizontal state and is ready for welding, in order to avoid interference caused by the holding plate on the top side, the user can rotate the holding plate on the top side to a vertical state.

When the user needs to take the unprocessed battery pack, the pedal on the bottom side can be rotated, and the second screw rod can be driven to rotate through the transmission effect of the first gear and the second gear. When the second screw rod rotates, the two threaded blocks on both sides move and the load plate is pushed to slide vertically on the supporting slide rod through the two lifting connecting rods. At this time, the user can adjust the height of the load plate according to the number of placed battery packs, which is convenient for the extraction of the battery pack. At the same time, because the diameter of the first gear used for transmission is smaller than the second gear, the user can save effort when driving through the pedal. Furthermore, In order to facilitate the transportation of the battery pack, a simple cart mainly composed of an installation side panel, a connecting plate push-pull rod and a second pulley is provided on the side of the operating table, by which the user can transport and transfer the battery pack. When the carrying plate is at the bottom position, if the installing side panel is moved close to the operating table, the connecting plate can be placed on the carrying plate, that is, the battery pack transported on the connecting plate can be directly carried on the carrying plate. At the same time, the connecting plate and the installing side panel are slidingly connected, so that the connecting plate can slide in the vertical direction with the carrying plate, which is convenient for directly extracting the transported battery pack. In order to improve the connection accuracy and stability between the installing side panel and the operating table, a second socket is opened on the side of the operating table to ensure that the connecting plate is correctly placed on the carrying plate. At the same time, when the protruding part of the side surface of the installing side panel is embedded in the second socket, the hook rod will also engage with the engaging groove to prevent the installing side panel from detaching. When the user needs to separate the installing side panel, he only needs to pull the push-pull rod to release it, which is convenient for transporting the battery pack.

When the resistance piece 211 is extended, it will prevent the current receiving plate 209 from rotating, thereby ensuring the clamping effect of the battery pack between the receiving plates 209. At the same time, in order to fix battery packs of different specifications, the user can rotate the first screw rod 206 to adjust the distance between the two clamping blocks 207 to ensure the stability of the battery pack when it is turned over. The sliding seat 205 is connected to the mounting plate 207 through the rotating shaft 202. The mounting arms 201 are rotatably connected. When in use, in order to facilitate the user to perform welding operations, when the holding plate 209 on one side is rotated to the top side, the end of the inner sliding piece 213 set at the other end thereof slides into the positioning groove 208 on the side of the mounting arm 201. At this time, under the action of the first spring 212, the corresponding contact piece 211 retracts. At this time, the user can rotate the holding plate 209 on the top side to a vertical state and expose the top side surface of the battery pack for convenient welding operations, while the holding plate 209 on the other side remains in a horizontal state under the interference effect of the corresponding contact piece 211 to support the battery pack. After completing the welding work on the current side, the holding plate 209 on the top side is rotated to a horizontal state, and then the battery pack and the sliding seat 205 are rotated as a whole. 180° is enough. In order to make the bottom holding plate 209 more stable, the user can rotate the locking rod 203 on the bottom side of the mounting arm 201 when the battery pack is rotated to a horizontal state, so that the end of the locking rod 203 passes through the rotating shaft 202, thereby preventing the rotating shaft 202 from continuing to rotate, which is convenient for welding the electrodes on both sides of the battery pack and the connecting pieces, and improves work efficiency. In order to prevent the battery pack from sliding sideways when rotating, a side slider 302 is provided on both sides of the holding plate 209. After the user completes the placement of the battery pack on the holding plate 209, the user can adjust the position of the side sliders 302 on one side to limit the two sides of the battery, thereby preventing the battery pack from sliding off. When moving the side sliders 302, the user needs to press the side sliders 302 at the same time. 02, so that the bottom end of the locking block 303 is released from the locking state with the sawtooth groove 301, and the side slider 302 slides to the specified position and releases the locking block 303. At this time, the locking block 303 and the sawtooth groove 301 can block the two sides of the battery pack to prevent the battery pack from sliding to the side when flipping, and improve the overall stability of the battery pack during welding, which is convenient for use. When the battery pack is in a horizontal state and is ready for welding, in order to avoid interference caused by the top side holding plate 209, the user can rotate the top side holding plate 209 to a vertical state. At this time, the holding plate 209 can be fixed by two clamping rods 405 arranged on the operating table 1, and the inner side of the clamping rod 405 is a slope structure.To facilitate the insertion of the holding plate 209, the release slider 401 located in the middle is located at the through hole 402 in the middle of the holding plate 209. The user can press the release slider 401 and then push the inclined blocks 403 on both sides to release the locking state of the clamping rod 405 on the holding plate 209, which is convenient for welding the battery pack. At the same time, when the holding plate 209 is in the locked state, it will also push the contact piece 211. At this time, the end of the inner slide piece 213 cannot slide out of the positioning groove 208, further increasing the stability of the device. A carrying plate 505 is provided on the other side of the operating table 1, which can be used to carry the battery pack. The user needs to weld the battery pack without adding When the user wants to take out the battery pack, he can rotate the pedal 501 on the bottom side, and the transmission effect of the first gear 506 and the second gear 507 drives the second screw rod 502 to rotate. When the second screw rod 502 rotates, the two threaded blocks 508 on both sides move and push the carrying plate 505 to slide vertically on the supporting slide rod 504 through the two lifting connecting rods 503. At this time, the user can adjust the height of the carrying plate 505 according to the number of battery packs placed, so as to facilitate the extraction of the battery packs. At the same time, because the diameter of the first gear 506 used for transmission is smaller than the second gear 507, the user can adjust the height of the carrying plate 505 according to the number of battery packs placed, so as to facilitate the extraction of the battery packs. At the same time, because the diameter of the first gear 506 used for transmission is smaller than the second gear 507, the user can adjust the height of the carrying plate 505 according to the number of battery packs placed. 1 is more labor-saving when driving. Furthermore, in order to facilitate the transportation of the battery pack, a simple cart mainly composed of the mounting side plate 601, the connecting plate 603 push-pull rod 602 and the second pulley 608 is provided on the side of the operating table 1. The user can use it to transport and transfer the battery pack. When the carrying plate 505 is at the bottom position, if the mounting side plate 601 is moved to be close to the operating table 1, the connecting plate 603 can be placed on the carrying plate 505, that is, the battery pack transported on the connecting plate 603 can be directly carried on the carrying plate 505. At the same time, the connecting plate 603 is slidably connected to the mounting side plate 601, so that the connecting plate 603 can slide vertically with the carrier plate 505, which is convenient for directly extracting the transported battery pack. In order to improve the connection accuracy and stability between the mounting side plate 601 and the operating table 1, a second plug hole 611 is opened on the side of the operating table 1 to ensure that the connecting plate 603 is correctly placed on the carrier plate 505. At the same time, when the protruding part of the side of the mounting side plate 601 is embedded in the second plug hole 611, the hook rod 609 will be engaged with the engaging groove 610 to prevent the mounting side plate 601 from being separated. When the user needs to separate the mounting side plate 601, he only needs to pull the push-pull rod 602 to release it, which is convenient for transporting the battery pack.
