[0016] The beneficial effects of the present invention are:

[0017] (1) A welding device for a battery packaging connection piece according to the present invention, wherein a placement structure is fixed on the operation table, and a limiting structure is arranged on the placement structure; different specifications of battery packs can be fixed through the placement structure, and at the same time, it is convenient to turn the battery pack to improve the welding efficiency. Through the limiting structure, it can be avoided that battery packs of different specifications slide during the rotation process, that is: First, two placing plates are slidably connected to the sliding seat. The two placing plates are used for placing the battery pack. The placing plate is rotatably connected to the clamping block. At the same time, through the setting of the limiting groove, the two placing plates can only rotate outward. A resisting piece slides inside the clamping block. When the resisting piece extends out, it will prevent the current placing plate from rotating, ensuring the clamping effect on the battery pack between the placing plates. At the same time, in order to fix battery packs of different specifications, the user can rotate the first lead screw to adjust the distance between the two clamping blocks to ensure the stability of the battery pack during flipping. The sliding seat is rotatably connected to the mounting arm through a rotating shaft. During use, in order to facilitate the user's welding operation, when one side of the placing plate rotates to the top side, the end of the inner sliding piece provided at the other end slides into the positioning groove on the side of the mounting arm. At this time, under the action of the first spring, the corresponding resisting piece retracts. At this time, the user can rotate the placing plate on the top side to the vertical state and expose the top side for placing the battery pack, which is convenient for welding operation. The placing plate on the other side remains in the horizontal state under the resisting effect of the corresponding resisting piece to support the battery pack. After completing the welding work on the current side, rotate the placing plate on the top side to the horizontal state, and then rotate the battery pack and the sliding seat part as a whole by 180°. In order to make the placing plate on the bottom side more stable, the user can rotate the locking rod at the bottom of the mounting arm when the battery pack rotates to the horizontal state, so that the end of the locking rod penetrates through the rotating shaft, thereby preventing the rotating shaft from continuing to rotate, which is convenient for welding the two electrodes of the battery pack and the connection piece, improving the work efficiency. In order to avoid the battery pack from sliding sideways when the battery pack is rotated, a side slider is provided on each side of the placing plate. After the user completes the placement of the battery pack on the placing plate, the user can adjust the positions of the two side sliders on one side to limit the two sides of the battery, thereby avoiding the battery pack from sliding. When moving the side slider, the user needs to press the engaging block on the side of the side slider at the same time, so that the bottom end of the engaging block is disengaged from the engagement state with the sawtooth groove. After the side slider slides to the designated position, release the engaging block. At this time, under the engaging action between the engaging block and the sawtooth groove, the two sides of the battery pack can be blocked, avoiding the battery pack from sliding sideways during flipping, and improving the overall stability of the battery pack during the welding process, which is convenient for use.

[0018] (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. At this time, the holding plate can be fixed by two clamping rods arranged on the operating table. The inner side of the clamping rod is a sloped structure, which is convenient for the holding plate to be embedded. At this time, the release slider located in the middle is located at the through hole position in the middle of the holding plate. The user can press the release slider and then push the slope blocks on both sides to release the locking state of the clamping rod for the holding plate, which is convenient for welding the battery pack. At the same time, when the holding plate is in a locked state, it will also push the contact plate. At this time, the end of the inner slide plate cannot slide out of the positioning groove, which further increases the stability of the device.

[0019] (3) A battery packaging connecting piece welding device described in the present invention, the side of the operating table is connected to a lifting structure, and the lifting structure is provided with a transport structure; the lifting structure can hold the unprocessed battery pack and facilitate the user to take it, and the transport structure can facilitate the transportation and use of the battery pack, that is: a load plate is provided on the other side of the operating table, which can be used to carry the battery pack. 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.

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0033] As Figures 1-10 shown, a welding device for battery packaging connection pieces according to the present invention includes an operating table 1, a placement structure 2 is fixed on the operating table 1, a limiting structure 3 is provided on the placement structure 2, a positioning structure 4 is provided on the top of the operating table 1, a lifting structure 5 is connected to the side of the operating table 1, and a transportation structure 6 is provided on the lifting structure 5.

[0034] Specifically, the placement structure 2 includes a mounting arm 201. The bottom side of the operating table 1 is fixedly connected to the mounting arm 201. One end of the mounting arm 201 is provided with a sliding seat 205. A rotating shaft 202 is fixedly connected to the side surface of the sliding seat 205. The rotating shaft 202 is rotatably connected to the mounting arm 201. Two clamping blocks 207 are provided on the sliding seat 205. A storage plate 209 is rotatably connected to the end of the clamping block 207. A contact piece 211 is slidably connected to the inner side of the clamping block 207. One side of the contact piece 211 abuts against the surface of the storage plate 209. The edge part of the storage plate 209 is in a right-angle bending shape. A limiting groove 210 is provided at the position where the clamping block 207 and the storage plate 209 rotate. The end of the storage plate 209 abuts against the clamping block 207 through the limiting groove 210. A first spring 212 is fixedly connected between the contact piece 211 and the clamping block 207. An inner sliding piece 213 is fixedly connected to the end of the contact piece 211. The inner sliding piece 213 is slidably connected to the clamping block 207. The clamping block 207 is slidably connected to the sliding seat 205. A first lead screw 206 is rotatably connected to the inner side of the sliding seat 205. The thread directions on both sides of the first lead screw 206 are opposite, and both sides of the first lead screw 206 are threadedly connected to the two clamping blocks 207 respectively. A positioning groove 208 is formed on the side surface of the mounting arm 201. The cross-section of the positioning groove 208 is in a trapezoidal structure. The end of the inner sliding piece 213 is in a trapezoidal structure. The end of the inner sliding piece 213 is slidably connected to the mounting arm 201. A locking rod 203 is threadedly connected to the bottom side of the mounting arm 201. A first insertion hole 204 is formed in the rotating shaft 202. The end of the locking rod 203 passes through the rotating shaft 202 through the first insertion hole 204;The battery packs of different specifications can be fixed through the placement structure 2, and at the same time, it is convenient to flip the battery packs to improve the welding efficiency, that is: First, two holding plates 209 are slidably connected to the sliding seat 205. The two holding plates 209 are used to place the battery packs. The holding plates 209 are rotatably connected to the clamping blocks 207. At the same time, the setting of the limiting groove 210 enables the two holding plates 209 to only rotate outward. A contact piece 211 slides inside the clamping block 207. When the contact piece 211 extends out, it will prevent the current holding plate 209 from rotating, ensuring the clamping effect on the battery pack between the holding plates 209. At the same time, in order to fix the battery packs of different specifications, the user can rotate the first lead screw 206 to adjust the distance between the two clamping blocks 207 to ensure the stability of the battery pack during flipping. The sliding seat 205 is rotatably connected to the mounting arm 201 through a rotating shaft 202. During use, in order to facilitate the user's welding operation, when one side of the holding plate 209 rotates to the top side, the end of the inner sliding piece 213 provided at the other end 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 top-side holding plate 209 to the vertical state and expose the top side for placing the battery pack, which is convenient for welding operation. The other holding plate 209 remains in the horizontal state under the contact effect of the corresponding contact piece 211 to support the battery pack. After completing the welding work on the current side, rotate the top-side holding plate 209 to the horizontal state, and then rotate the battery pack and the sliding seat 205 part as a whole by 180°. In order to make the bottom-side holding plate 209 more stable, the user can rotate the locking rod 203 at the bottom of the mounting arm 201 when the battery pack rotates to the horizontal state, so that the end of the locking rod 203 penetrates through the rotating shaft 202, thereby preventing the rotating shaft 202 from continuing to rotate, facilitating the welding work of the two electrodes of the battery pack and the connecting piece, and improving the work efficiency.;

[0035] Specifically, the limiting structure 3 includes sawtooth grooves 301. Two sawtooth grooves 301 are symmetrically formed on the placing plate 209. The placing plate 209 is slidably connected with side sliders 302 through the sawtooth grooves 301. The side sliders 302 are in a "T" shape. The inner sides of the side sliders 302 are slidably connected with engaging blocks 303. A second spring 304 is fixedly connected between the engaging blocks 303 and the side sliders 302. The ends of the engaging blocks 303 are engaged with the placing plate 209 through the sawtooth grooves 301. The limiting structure 3 can prevent battery packs of different specifications from slipping during rotation, that is, in order to prevent the battery pack from slipping sideways when the battery pack is rotated, one side slider 302 is provided on each side of the placing plate 209. After the user completes the placement of the battery pack on the placing plate 209, the user can adjust the positions of the two side sliders 302 on one side to limit both sides of the battery, thereby preventing the battery pack from slipping. When moving the side sliders 302, the user needs to press the engaging blocks 303 on the sides of the side sliders 302 at the same time, so that the bottom ends of the engaging blocks 303 are disengaged from the engagement state with the sawtooth grooves 301. After the side sliders 302 slide to the designated positions, the engaging blocks 303 are released. At this time, under the engagement of the engaging blocks 303 and the sawtooth grooves 301, both sides of the battery pack can be blocked, preventing the battery pack from sliding sideways during flipping, and improving the overall stability of the battery pack during the welding process, which is convenient for use.

At this time, the placing plate 209 can be fixed by the two clamping rods 405 arranged on the operating table 1. The inner sides of the clamping rods 405 are in a slope structure, which is convenient for the placing plate 209 to be inserted. At this time, the release slider 401 located in the middle is at the position of the through hole 402 in the middle of the placing plate 209. The user can press the release slider 401 to push the slope blocks 403 on both sides to release the locking state of the clamping rods 405 on the placing plate 209, which is convenient for welding the battery pack. At the same time, when the placing plate 209 is in the locked state, it will also push the contact piece 211. At this time, the end of the inner sliding piece 213 cannot slide out of the positioning groove 208, further increasing the stability of the device.

A first gear 506 is engaged with the side surface of the second gear 507, and the diameter of the first gear 506 is smaller than that of the second gear 507. A pedal 501 is fixedly connected to the middle of the first gear 506. The pedal 501 is rotatably connected to the operating table 1; the lifting structure 5 can be used to hold the unprocessed battery pack and is convenient for the user to take. That is, a bearing plate 505 is provided on the other side of the operating table 1 for carrying the battery pack. When the user needs to take the unprocessed battery pack, the pedal 501 located at the bottom can be rotated. Through the transmission effect of the first gear 506 and the second gear 507, the second lead screw 502 is driven to rotate. When the second lead screw 502 rotates, the two threaded blocks 508 on both sides move and simultaneously push the bearing plate 505 to slide vertically on the support sliding rods 504 through the two lifting connecting rods 503. At this time, the user can adjust the height of the bearing plate 505 according to the number of the placed battery packs, which is convenient for extracting the battery packs. At the same time, since the diameter of the first gear 506 used for transmission is smaller than that of the second gear 507, it is more labor-saving for the user to drive through the pedal 501.

[0038] Specifically, the transportation structure 6 includes a connecting plate 603. The top side of the bearing plate 505 is provided with a connecting plate 603. The side of the operating table 1 is provided with a mounting side plate 601. The mounting side plate 601 and the bearing plate 505 are perpendicular to each other.

A limit stop 606 is fixedly connected to the mounting side plate 601. A fourth spring 607 is fixedly connected between the limit stop 606 and the push-pull rod 602. The end of the push-pull rod 602 is fixedly connected with a hook rod 609. A clamping groove 610 is formed inside the operating table 1. The end of the hook rod 609 is engaged with the operating table 1 through the clamping groove 610. The transportation and extraction of the battery pack can be facilitated through the transportation structure 6. That is, further, in order to facilitate the transportation of the battery pack, a simple trolley mainly composed of a mounting side plate 601, a connecting plate 603, a push-pull rod 602, and a 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 bearing plate 505 is at the bottommost position, if the mounting side plate 601 moves to be close to the operating table 1, the connecting plate 603 can just be placed on the bearing plate 505. That is, the battery pack transported on the connecting plate 603 can be directly carried on the bearing 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 bearing 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 jack 611 is formed on the side of the operating table 1 to ensure that the connecting plate 603 is correctly placed on the bearing plate 505. At the same time, when the protruding part on the side of the mounting side plate 601 is inserted into the second jack 611, the hook rod 609 will be engaged with the clamping groove 610 at the same time, avoiding the separation of the mounting side plate 601. When the user needs to separate the mounting side plate 601, just pull the push-pull rod 602 to release it, which is convenient for transporting the battery pack.

[0039] When the present invention is in use, first, two placing plates 209 are slidably connected to the sliding seat 205. The two placing plates 209 are used for placing the battery pack. The placing plates 209 are rotatably connected to the clamping blocks 207. At the same time, due to the arrangement of the limiting grooves 210, the two placing plates 209 can only rotate outward. A resisting piece 211 slides inside the clamping block 207. When the resisting piece 211 extends out, it will prevent the current placing plate 209 from rotating, ensuring the clamping effect on the battery pack between the placing plates 209. At the same time, in order to fix battery packs of different specifications, the user can rotate the first lead screw 206 to adjust the distance between the two clamping blocks 207, ensuring the stability of the battery pack during flipping. The sliding seat 205 is rotatably connected to the mounting arm 201 through a rotating shaft 202. When in use, in order to facilitate the user's welding operation, when one of the placing plates 209 rotates to the top side, the end of the inner sliding piece 213 provided at the other end 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 resisting piece 211 retracts. At this time, the user can rotate the placing plate 209 on the top side to the vertical state and expose the top side for placing the battery pack, facilitating the welding operation. The other placing plate 209 remains in the horizontal state under the resisting effect of the corresponding resisting piece 211 to support the battery pack. After completing the welding work on the current side, rotate the placing plate 209 on the top side to the horizontal state, and then rotate the battery pack and the sliding seat 205 part as a whole by 180°. In order to make the placing plate 209 on the bottom side more stable, the user can rotate the locking rod 203 at the bottom of the mounting arm 201 when the battery pack rotates to the horizontal state, so that the end of the locking rod 203 penetrates through the rotating shaft 202, thereby preventing the rotating shaft 202 from continuing to rotate, facilitating the welding work on both sides of the electrodes of the battery pack and the connecting piece, and improving the work efficiency. In order to prevent the battery pack from slipping sideways when the battery pack is rotated, a side slider 302 is provided on each side of the placing plate 209. After the user completes the placement of the battery pack on the placing plate 209, the user can adjust the positions of the two side sliders 302 on one side to limit both sides of the battery, thereby preventing the battery pack from slipping. When moving the side slider 302, the user needs to press the engaging block 303 on the side of the side slider 302 at the same time, so that the bottom end of the engaging block 303 is disengaged from the engagement state with the sawtooth-shaped groove 301. After the side slider 302 slides to the designated position, release the engaging block 303. At this time, under the engagement between the engaging block 303 and the sawtooth-shaped groove 301, both sides of the battery pack can be blocked, preventing the battery pack from sliding sideways during flipping, and improving the overall stability of the battery pack during the welding process, facilitating use. When the battery pack is in the horizontal state and ready for welding, in order to avoid interference from the placing plate 209 on the top side, the user can rotate the placing plate 209 on the top side to the vertical state. At this time, the placing plate 209 can be fixed by two clamping rods 405 provided on the operating table 1. The inner side of the clamping rod 405 is of an inclined surface structure.The convenient storage plate 209 is embedded. At this time, the release slider 401 located in the middle is at the position of the through hole 402 in the middle of the storage 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 storage plate 209, which is convenient for welding the battery pack. At the same time, when the storage plate 209 is in the locked state, it will also push the contact piece 211. At this time, the end of the inner slider 213 cannot slide out of the positioning groove 208, further increasing the stability of the device. On the other side of the operation table 1, there is a carrier plate 505, which can be used to carry the battery pack. When the user needs to take the unprocessed battery pack, the pedal 501 located at the bottom can be rotated. Through the transmission effect of the first gear 506 and the second gear 507, the second lead screw 502 is driven to rotate. When the second lead screw 502 rotates, the two threaded blocks 508 on both sides move and at the same time push the carrier plate 505 to slide vertically on the support slide rod 504 through the two lifting connecting rods 503. At this time, the user can adjust the height of the carrier plate 505 according to the number of battery packs placed, which is convenient for extracting the battery pack. At the same time, because the diameter of the first gear 506 used for transmission is smaller than that of the second gear 507, it is more labor-saving for the user to drive through the pedal 501. Further, in order to facilitate the transportation of the battery pack, on the side of the operation table 1, there is a simple trolley mainly composed of an installation side plate 601, a connecting plate 603, a push rod 602 and a second pulley 608. The user can use it to transport and transfer the battery pack. When the carrier plate 505 is at the bottommost position, if the installation side plate 601 moves to be close to the operation table 1, the connecting plate 603 can just be placed on the carrier plate 505, that is, the battery pack transported on the connecting plate 603 can be directly carried on the carrier plate 505. At the same time, the connecting plate 603 is slidably connected to the installation side plate 601, so that the connecting plate 603 can slide vertically together 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 installation side plate 601 and the operation table 1, a second jack 611 is opened on the side of the operation 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 on the side of the installation side plate 601 is embedded inside the second jack 611, the hook rod 609 will be engaged with the engaging groove 610 at the same time, avoiding the separation of the installation side plate 601. When the user needs to separate the installation side plate 601, just pull the push rod 602 to release it, which is convenient for transporting the battery pack.,
