[0057] Embodiment 1:

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the present embodiment proposes a lithium battery plate welding mold, including an operating table 1, a battery slot 9 is provided in the middle of the upper surface of the operating table 1, an outlet slot 10 is provided at the top of one side wall of the battery slot 9, a cross slot 11 is provided on both side walls of the battery slot 9, a limiting slot A12 and a gear slot A13 are respectively provided on both sides of the two side walls of the battery slot 9 close to the cross slot 11, an L-shaped slot 14 is provided on the other side wall of the battery slot 9, a limiting slot B15 and a gear slot B16 are respectively provided on both sides of the other side wall of the battery slot 9 close to the L-shaped slot 14, and a side lower slot is installed together inside the cross slot 11, the limiting slot A12 and the gear slot A13. The side sinking clamping mechanism 2 is set up, and after the lithium battery is placed on the surface of the bottom support plate 206, the bottom support plate 206 will drop under the action of gravity. At this time, with the cooperation of the linkage gear A203 and the rack A204, the side clamping plate 207 gradually abuts against the outer wall of the lithium battery. After the L-shaped support member 205 contacts the inner bottom wall of the battery slot 9, the side clamping plate 207 abuts against the outer wall of the lithium battery, and the lithium battery is well clamped and fixed to avoid movement during welding, thereby ensuring the welding effect. The L-shaped slide groove 14, the limit slide groove B15 and the gear groove B16 are jointly installed with a linkage pushing mechanism 3. The groove 14, the limiting slide groove B15 and the gear groove B16 are jointly installed with a linkage push-out mechanism 3. Through the setting of the linkage push-out mechanism 3, it is realized that when the lithium battery plate is welded, the linkage top plate 403 is raised upward, and the lifting component 5 is driven to rise at the same time, thereby driving the L-shaped slide bar 301 to rise upward. During the process, with the cooperation of the linkage gear B303 and the rack B304, the limiting slide bar B302 pushes the push plate 305 to move to one side of the lithium battery, and then in the process of gradual lifting, the welded lithium battery is gradually pushed out of the battery slot 9 to the receiving component 6, so that the personnel can easily take the lithium battery away, and the upper part of the operating table 1 is The surface is fixedly connected with a lifting welding mechanism 4. Through the provided lifting welding mechanism 4, during welding, the electric push rod 402 drives the linkage top plate 403 to descend, so that the welding gun 404 contacts the surface of the lithium battery, and then the lithium battery can be welded by the welding gun 404. After the welding is completed, the linkage top plate 403 is driven to rise by the electric push rod 402, and then the side sinking clamping mechanism 2 and the linkage pushing mechanism 3 can be driven to move synchronously, so that the lithium battery can be easily taken away. The top of the linkage pushing mechanism 3 is fixedly connected with a lifting component 5, and the front of the operating table 1 is installed with a receiving component 6 for receiving the lithium battery after welding.

[0059] The lifting welding mechanism 4 includes a mounting frame 401 fixed to the operating table 1, and electric push rods 402 are fixedly installed on both sides of the lower surface of the mounting frame 401, one end of the electric push rod 402 is fixedly connected to a linkage top plate 403, and a welding gun 404 is fixedly installed on the lower surface of the linkage top plate 403. A limited position frame 405 is welded on one side of the linkage top plate 403, and fixing plates are welded to the bottoms of both sides of the mounting frame 401. Fixing bolts are threaded through the fixing plates, and the mounting frame 401 is fixed to the operating table 1 through the fixing bolts. The end of the electric push rod 402 is fixedly connected to a mounting plate, and a positioning bolt is threaded through the mounting plate. The positioning bolts fix the linkage top plate 403 to the lower surface of the mounting plate, so that the electric push rod 402 can drive it to move up and down. In the process of the electric push rod 402 driving the linkage top plate 403 to move upward, the side sinking clamping mechanism 2 can be driven to rise upward.

[0060] Specifically, first, the lithium battery is placed in the battery slot 9 at a position away from the outlet slot 10. During the process of the electric push rod 402 driving the linkage top plate 403 to descend, the side sinking clamping mechanism 2 moves downward under the action of the gravity of the lithium battery, and gradually clamps the lithium battery. During the downward process, the linkage pushing mechanism 3 is retracted inward. At this time, the linkage top plate 403 is then driven to descend by the electric push rod 402 to make the welding gun 404 contact with the lithium battery, and then the lithium battery plates are welded. After completion, the linkage top plate 403 is raised upward, and the lifting component 5 is raised upward on the left side of the limit frame 405, and the side sinking clamping mechanism 2 is simultaneously pulled upward. At this time, the fixation of the lithium battery is gradually released. During the process, the linkage pushing mechanism 3 gradually pushes the lithium battery to the outlet slot 10, so that it falls onto the receiving component 6.

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11As shown, the side sinking clamping mechanism 2 includes a cross slide 201 slidably connected to the cross slide 11, a limit slide A202 slidably connected to the limit slide A12, and a linkage gear A203 rotatably connected to the gear groove A13. One side of the cross slide 201 and the lower surface of the limit slide A202 are fixedly connected to the rack A204 meshing with the linkage gear A203. The bottom of the other side of the cross slide 201 is welded with an L-shaped support member 205. The L-shaped support member 205 is welded to the bottom of the cross slide 201. The top of 05 is fixedly connected with a bottom support plate 206, one end of the limit slide A202 is fixedly connected with a side clamp plate 207, and a non-slip rubber pad is pasted on one side of the side clamp plate 207. When the lithium battery is placed on the bottom support plate 206, the bottom support plate 206 descends under the action of the gravity of the lithium battery, and at the same time drives the cross slide 201 to descend. During the descent of the cross slide 201, the rack A204 on it drives the linkage gear A203 to rotate counterclockwise, and the gear on the lower surface of the limit slide A202 The bar A204 is in meshing state with the linkage gear A203, so that when it rotates, the two limit sliders A202 in the battery slot 9 can move, the one located on the left wall moves from right to left, and the one located on the right wall moves from left to right, so that the two side clamps 207 are against the outer wall of the lithium battery, clamping and fixing the lithium battery to prevent it from shaking during welding. The L-shaped support member 205 can provide good stable support for the bottom support plate 206. After welding is completed, the linkage top plate 403 is lifted upward with the welding gun 404, and the lifting assembly 5 is lifted in the process, thereby lifting the linkage ejection mechanism 3, and then driving the bottom support plate 206 to rise upward, and at the same time driving the cross slider 201 to rise. During the lifting process of the cross slider 201, the linkage gear A203 is driven to rotate clockwise. At the same time, the linkage gear A203 drives the two limit sliders A202 to move, the one located on the left wall moves from left to right, and the one located on the right wall moves from right to left, thereby releasing the restriction on the lithium battery.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11As shown, the linkage ejection mechanism 3 includes an L-shaped slide bar 301 slidably connected to the L-shaped slide groove 14, a limit slide bar B302 slidably connected to the limit slide groove B15, and a linkage gear B303 rotatably connected to the gear groove B16. One side of the front side of the L-shaped slide bar 301 and the lower surface of the limit slide bar B302 are fixedly connected with a rack B304 adapted to the linkage gear B303. One end of the limit slide bar B302 is fixedly connected with a push plate 305. The back side of the bottom support plate 206 is fixedly connected to the bottom of the other side of the front side of the L-shaped slide bar 301. The linkage gear A203 has the same number of teeth as the linkage gear B303. When the bottom support plate 206 descends, the L-shaped slide bar 301 can be driven to descend at the same time, and the rack B304 thereon can be driven to descend. 4 descends synchronously, thereby driving the meshing linkage gear B303 to rotate counterclockwise, thereby causing the limiting slide bar B302 with a rack B304 on the lower surface to move from front to back, thereby driving the push plate 305 to gradually move to contact the inner wall of the battery slot 9. When welding is completed, the linkage top plate 403 rises upward with the welding gun 404, gradually driving the lifting assembly 5 to rise during the process, thereby driving the L-shaped slide bar 301 to move upward, thereby driving the meshing linkage gear B303 with the rack B304 on the front thereof to rotate clockwise, thereby driving the limiting slide bar B302 with a rack B304 on the lower surface to move from back to front, thereby driving the push plate 305 to gradually contact the lithium battery and push it out to the outlet slot 10.

[0063] Embodiment 2:

[0064] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0065] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11As shown, as a preferred embodiment, on the basis of the above method, further, the lifting component 5 includes a linkage bottom plate 501 fixedly connected to the top of the L-shaped slide 301, and the upper surface of the linkage bottom plate 501 is fixedly connected with a guide plate 502, and one end of the guide plate 502 passes through the limit frame 405 and is fixedly connected to the limit plate 503. After the side clamp 207 clamps the lithium battery, the limit plate 503 is in contact with the limit frame 405, but the welding gun 404 is still away from the lithium battery at this time. When the lithium battery needs to be welded, the position of the welding gun 404 needs to be further lowered. At this time, the limit plate 503 is away from the limit frame 405. After the welding is completed, the linkage top plate 403 is raised upward by the electric push rod 402. First, the limit frame 405 gradually contacts the limit plate 503, and then the L-shaped slide 301 is pulled upward, and then the bottom support plate 206 fixed to the L-shaped slide 301 is driven upward.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, an installation groove is opened on the inner bottom wall of the outlet groove 10, and a plurality of rotating shafts 7 are rotatably connected to the inside of the installation groove through bearings. The rotating shafts 7 are in an inclined state, so that the lithium battery can slide toward the side of the receiving component 6 more easily. When the push plate 305 gradually pushes the welded lithium battery toward the outlet groove 10, when it is pushed onto the outlet groove 10, the lithium battery gradually slides forward under the action of the rotating shaft 7, and finally slides onto the receiving component 6. At this time, it is easier and faster for personnel to take the welded lithium battery.

[0067] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the receiving component 6 includes a receiving platform 601 fixed to the operating table 1, a baffle 602 is welded at the edge of one side of the upper surface of the receiving platform 601, and both sides and the middle of the lower surface of the receiving platform 601 are welded with an inclined support plate 603, one end of the inclined support plate 603 is fixedly connected to the middle of the front of the operating table 1, and an inclined installation groove is opened in the middle of the upper surface of the receiving platform 601, and a plurality of gradually inclined to one side are rotatably connected inside the inclined installation groove. Roller 604, a limiting baffle 605 is welded at one end of the receiving platform 601, and a sponge anti-collision pad is provided on the back of the inclined support plate 603. The lithium battery will gradually slide onto the receiving platform 601 under the action of the rotating shaft 7, and the inclined support plate 603 can limit the lithium battery to prevent it from directly sliding off the receiving platform 601, and the sponge anti-collision pad can play a certain protective effect to prevent the lithium battery from being damaged in a collision. A row of inclined rollers 604 can make the lithium battery that slides onto the receiving platform 601 gradually slide to one side and gather, making it convenient for people to take it.

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the lower surface of the operating table 1 is fixedly connected with a supporting leg 8, the bottom end of the supporting leg 8 is fixedly connected with a chassis, and the lower surface of the chassis is engraved with anti-slip grooves, so that the chassis has good anti-slip performance, and together with the supporting leg 8, the operating table 1 can be stably placed in position.

[0069] Embodiment 3:

[0070] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0071] Specifically, when the lithium battery plate welding mold is working / in use:

[0072] 1. First, place the lithium battery on the bottom support plate 206 parallel to the outlet slot 10, then push the lithium battery inward to make it gradually move inward. At this time, the lithium battery is completely placed on the surface of the bottom support plate 206, and when moving inward, the bottom support plate 206 drops downward a certain distance, and then under the action of the gravity of the lithium battery, the bottom support plate 206 continues to drop to a lower position, and during the process, the cross slide 201 is driven to drop. During the descent, the rack A204 on it drives the linkage gear A203 to rotate counterclockwise, and at this time, the limit slide A202 with another rack A204 fixedly connected to the lower surface is driven to move synchronously. The limit slide A202 located on the left wall of the battery slot 9 moves from right to left, and the limit slide A202 located on the right wall of the battery slot 9 moves from left to right, so that the side clamps 207 at the ends of the two limit slides A202 gradually abut against the outer wall of the lithium battery, clamping and fixing the lithium battery, and the bottom During the process of the support plate 206 descending, the L-shaped slide bar 301 will be pulled down at the same time, and the rack B304 on it will descend synchronously, thereby driving the meshing linkage gear B303 to rotate counterclockwise, and then the limiting slide bar B302 with the rack B304 on the lower surface moves from front to back, thereby driving the push plate 305 to gradually move until it contacts the inner wall of the battery slot 9. At this time, the push plate 305 is away from the lithium battery. During the process of the bottom support plate 206 descending, the electric push rod 402 is started at the same time, and the linkage top plate 403 is pushed down by the electric push rod 402. When the bottom support plate 206 descends until the L-shaped support member 205 contacts the bottom wall of the battery cavity, the welding gun 404 is still a distance away from the lithium battery. At this time, the linkage top plate 403 is then pushed down by the electric push rod 402 until the welding gun 404 contacts the surface of the lithium battery, and then the welding gun 404 performs the plate welding operation on the lithium batteries in each battery slot 9;

[0073] 2. After welding is completed, the electric push rod 402 is started again to make the linkage top plate 403 rise upward. During the rising process, the limit frame 405 gradually contacts with the limit plate 503. After contact, the guide plate 502 can be pulled upward, and the three L-shaped slide bars 301 are driven to move upward synchronously through the linkage bottom plate 501 at the bottom of the guide plate 502, and the rack B304 on the front thereof moves upward together, and then the meshing linkage gear B303 rotates clockwise, and at the same time drives the limit slide bar B302 with the rack B304 fixedly connected on the lower surface to move from back to front, and then drives the push plate 305 to gradually contact with the lithium battery. In the process of the L-shaped slide bar 301 moving upward, the bottom support plate 206 will be pulled upward synchronously, and the cross slide bar 201 will be driven to rise at the same time. During the rising process of the cross slide bar 201, the rack A20 on its surface 4 drives the linkage gear A203 to rotate clockwise, and at the same time, the linkage gear A203 drives the limit slider A202 to move, and the limit slider A202 located on the left side wall of the battery slot 9 moves from left to right, and the limit slider A202 located on the left side wall of the battery slot 9 moves from right to left, so as to release the restriction on the lithium battery. When the bottom support plate 206 is raised to be flush with the outlet slot 10, the push plate 305 will push the lithium battery to the edge of the bottom support plate 206. When the bottom support plate 206 continues to rise for a certain height, the push plate 305 can push half of the lithium battery into the outlet slot 10. At this time, the lithium battery slides forward by itself under the action of the rotating shaft 7, and gradually slides to the receiving platform 601. The roller 604 can make the lithium battery gradually slide to one side and gather. At this time, the personnel can easily take away the welded lithium battery, and repeat the above operation when welding again.
