Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution for a lithium battery cap pressure welding device. The utility model will be further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] A lithium battery cap pressure welding device comprises a workbench 1, a clamping assembly 2 and a movable seat 20, wherein two clamping assemblies 2 are provided and are located on both sides of the top of the workbench 1, the clamping assembly 2 comprises a lifting platform 3, a rotating motor 4 is provided on the top of the lifting platform 3, an output end of the rotating motor 4 is fixedly connected to a fixed seat 5 through a rotating shaft, a connecting plate 6 is slidably connected inside the fixed seat 5, a sleeve block 8 is fixedly connected to one side of the connecting plate 6, a hydraulic telescopic rod 7 is provided on one side of the connecting plate 6 close to the sleeve block 8, one end of the hydraulic telescopic rod 7 passes through the connecting plate 6 and the sleeve block 8 respectively and is fixedly connected to a fixed block 9, first connecting blocks 12 are fixedly installed on both sides of the fixed block 9, a connecting strip 13 is rotatably connected to the top of the first connecting block 12 through a rotating shaft, and a clamping plate 14 is fixedly connected to the other end of the connecting strip 13.

[0026] Specifically, second connecting blocks 10 are fixedly installed on both sides of the sleeve block 8. The top of the second connecting block 10 is rotatably connected to a movable bar 11 through a rotating shaft. The other end of the movable bar 11 is movably connected to one side of the connecting bar 13 close to the clamping plate 14 through the rotating shaft.

[0027] Furthermore, a rotating motor 16 is provided on one side of the fixing seat 5 , a screw rod 17 is fixedly connected to the output end of the rotating motor 16 and penetrates into the fixing seat 5 , and a side of the connecting plate 6 away from the clamping plate 14 is threadedly connected to the screw rod 17 .

[0028] Furthermore, a movable cavity 15 is provided inside the connecting plate 6 on one side close to the screw rod 17, one end of the screw rod 17 is fixedly connected to a limit block 18, the limit block 18 is slidably connected to the side wall of the movable cavity 15, and a counterweight block 19 is provided on one side of the bottom of the fixing seat 5 close to the screw rod 17. The limit block 18 can prevent the connecting plate 6 from falling out of the fixing seat 5, and the counterweight block can keep the weight balanced at both ends of the fixing seat 5, so as to prevent the clamping device 2 from tipping over due to the unbalanced weight on both sides.

[0029] When used specifically, Figure 1 , Figure 2 and Figure 3 , Figure 4As shown, when the pressure welding work is started, the clamping assembly 2 on one side is first lifted to the specified height through the lifting platform 3, and then the screw rod 17 is rotated 1 by the rotating motor 16, and the connecting plate 6 will move inside the fixing seat 5 until it moves to the position where the lithium battery is located, and the rotating motor 16 stops working. Through the cooperation between the lifting platform 3 and the rotating motor 16, the clamping assembly 2 can be adjusted to the position where the lithium battery is located, so as to facilitate the taking of objects; then the hydraulic telescopic rod 7 is made to push the fixing block 9 toward the outside of the connecting plate 6, and the movement of the fixing block 9 will drive the first connecting block 12 to move, and because one end of the connecting strip 13 is connected to the movable strip 11 and the other end of the movable strip 11 is fixed on the second connecting block 10, it is impossible to fix the movable strip 11 and the connecting strip 13. After that, the other side of the connecting bar 13 will be forced to open the two clamping plates 14 outwards to facilitate clamping the lithium battery. After that, the hydraulic telescopic rod 7 is moved to the inside of the connecting plate 6, and the above operation is repeated. The end of the connecting bar 13 connected to the movable bar 11 pushes the clamping plate 14 inwards to clamp the lithium battery. Then, the clamping device 2 is rotated to one side of the movable seat 20 by the rotating motor 4. The angle and height are adjusted by the lifting platform 3 and the rotating motor 16 to place the lithium battery on the movable seat 20. Then, the operation is repeated to place the cap into the through hole 29 at the top of the placement plate 28. At this time, a set of loading operations is completed. After the first set of movable seats 20 leave, the loading of the next set continues; after the pressure welding is completed, another clamping component 2 also removes the lithium battery through the above operation. The automation of loading and unloading is realized by this device, and there is no need for manual material collection and unloading of lithium batteries, which saves labor, improves work efficiency, reduces manual operation and intervention, and avoids the occurrence of safety accidents.

[0030] Embodiment 2:

[0031] On the basis of the first embodiment, a lithium battery cap pressure welding device is provided, wherein a plurality of movable seats 20 are provided and slidably connected to the top surface of the workbench 1, connecting frames 21 are evenly arranged on the four sides of the bottom of the movable seat 20, and a movable motor 22 is arranged on one opposite side of the connecting frame 21, and the output end of the movable motor 22 is fixedly connected to a self-locking universal wheel 23 through a rotating shaft, and the self-locking universal wheel 23 is movably connected in the connecting frame 21.

[0032] Specifically, a moving groove 30 is provided on the top of the workbench 1 , and two sliding grooves 31 are provided at the bottom of the moving groove 30 . The bottom of the sliding groove 31 is slidably connected to the bottom of the self-locking universal wheel 23 .

[0033] Furthermore, mounting frames 24 are installed on both sides of the top of the moving seat 20, and a first electric push rod 25 is arranged in the mounting frame 24. The other end of the first electric push rod 25 is fixedly connected to a stabilizing plate 26. A plurality of second electric push rods 27 are arranged on the four sides of the top of the moving seat 20 and located outside the mounting frame 24. A placement plate 28 is fixedly connected to the top of the second electric push rod 27, and a through hole 29 is opened in the middle of the placement plate 28.

[0034] Furthermore, an L-shaped support plate 32 is fixedly connected to one side surface of the top of the workbench 1 , a pressure cylinder 33 is provided on the top of the L-shaped support plate 32 , a pressure welding column 34 is fixedly connected to the output end of the pressure cylinder 33 , and the pressure welding column 34 passes through the top of the L-shaped support plate 32 .

[0035] When used specifically, Figure 1 , Figure 2 and Figure 5 As shown, after the first clamping assembly 2 places the lithium battery on the movable seat 20, the first electric push rod 25 pushes the stabilizing plate 26 to clamp it firmly to prevent the lithium battery from shifting, and then the movable motor 22 is turned on to rotate the self-locking universal wheel 23, and the self-locking universal wheel 23 will drive the movable seat 20 to slide inside the slide groove 31. When it moves to the L-shaped support plate 32, the movable motor 22 stops working, and the self-locking universal wheel 23 stops rotating and is locked to prevent the movable seat 20 from moving during the cap pressing process and causing the pressure welding to deviate; then the pressure cylinder 33 is used to move the pressure welding column 34 downward to pressure weld the cap from the through hole 29 to the lithium battery. The surface is pressed and welded; then the self-locking universal wheel 23 is unlocked, and the mobile motor 22 rewrites the work and moves the mobile seat 20 to the second clamping component 2. The stabilizing plate 26 releases the lithium battery, and the clamping component 2 takes it out and prevents it from being collected uniformly in the external collection box. At this time, the pressure welding of a lithium battery and the cap is completed, and the mobile seat 20 returns to the first clamping component 2 for a new round of transportation. Multiple groups of mobile seats 20 will transfer the lithium batteries and caps for pressure welding in turn and at intervals, and can continuously perform pressure welding on the lithium batteries and caps, thereby improving work efficiency, reducing pressure welding costs, and making the device more practical.
