Description

Technical Field

[0001] This utility model relates to the field of solid-state battery tab processing technology, and more specifically to a solid-state battery tab pressing device. Background Technology

[0002] In the construction of solid-state batteries, the tabs, as key metallic conductors leading from the cell to the positive and negative electrodes, have a decisive impact on the overall battery performance. During the manufacturing process, the upper and lower surfaces of the metal strip need to be sealed with solid sealant. A thermal bonding machine is essential for this sealing process. However, air bubbles are easily generated during the thermal bonding of the metal strip and solid sealant in solid-state lithium batteries. These bubbles reduce the conductivity of the metal strip, thus affecting battery performance. Therefore, it is particularly necessary to use a specialized rolling device to remove air bubbles. Chinese patent (CN222422273U) discloses "A Solid-State Battery Tab Edge Pressing Device." This patent is highly versatile, can quickly adjust the edge pressing position to meet edge pressing requirements, saves raw materials consumed during adjustment, shortens the adjustment time, increases production capacity, and eliminates the curling effect generated during edge pressing.

[0003] In the existing technology, there are still inconveniences in adjusting the spacing between the upper and lower bolt bearings. On the one hand, the upper and lower bolt bearings of the fixed side column and the sliding side column cannot be adjusted synchronously, which easily leads to spacing errors in the upper and lower bolt bearings on both sides. On the other hand, the device performs edge pressing in two processes, and the spacing between the upper and lower bolt bearings in the two processes cannot be adjusted synchronously, which affects the operating efficiency. Utility Model Content

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1 and Figure 2This utility model provides a solid-state battery tab pressing device, including a fixed base 1 and a sliding base 2. Two pressing roller columns 3 are mounted on the fixed base 1 and the sliding base 2. Each pressing roller column 3 includes two roller columns 31. The inner side of each roller column 31 is provided with a sliding groove, and a sliding block 32 is slidably sleeved in each of the two sliding grooves. A lower bolt bearing 33 is fixedly installed on the inner side of each roller column 31, and an upper bolt bearing 34 is fixedly installed on the inner side of each sliding block 32. A rotary lifting mechanism 35 is installed on the top of each roller column 31. The output ends of the two rotary lifting mechanisms 35 are respectively fixedly connected to the top of the two sliding blocks 32. The two rotary lifting mechanisms 35 are used to control the lifting of the two sliding blocks 32. The control ends of the two rotary lifting mechanisms 35 are connected through a rotary drive rod 36. The rotation of the rotary drive rod 36 controls the operation of the two rotary lifting mechanisms 35.

[0022] In use, the lower bolt bearing 33 and upper bolt bearing 34 on the two roller columns 31 are used for pressing. When adjusting the distance between the lower bolt bearing 33 and upper bolt bearing 34, the two rotary lifting mechanisms 35 can be driven to run synchronously by rotating the rotary drive rod 36. The synchronous operation of the two rotary lifting mechanisms 35 can control the synchronous sliding of the two sliding blocks 32 to adjust the height. Through the connection between the sliding block 32 and the upper bolt bearing 34, the upper bolt bearing 34 on the two roller columns 31 can be adjusted synchronously, ensuring that the distance between the lower bolt bearing 33 and upper bolt bearing 34 on the fixed base 1 and the sliding base 2 can be adjusted synchronously, improving convenience and avoiding errors.

[0023] Reference Figure 2 The two pressure roller columns 3 are connected by a transmission rod assembly 4, which drives the two rollers 36 to rotate synchronously.

[0024] By setting the transmission rod assembly 4 to link the rotary drive rods 36 of the two pressing roller columns 3, the lower bolt bearings 33 and upper bolt bearings 34 of the two pressing roller columns 3 can be synchronously adjusted by rotating one rotary drive rod 36 during use, further improving the convenience of adjustment.

[0025] Reference Figure 3The roller column 31 has a through hole at its top for entering the slide groove. Two protrusions are provided at the top of the roller column 31. The rotary lifting mechanism 35 includes a fixed ring 351, which is fixedly connected to the top of the roller column 31. The fixed ring 351 has an annular groove on its side wall, and a rotating ring 352 is rotatably sleeved in the annular groove. A cylindrical ring wall 353 is fixedly connected to the side wall of the rotating ring 352. A worm gear 354 is fixedly connected to the side wall of the cylindrical ring wall 353. A worm 357 is meshed with the side wall of the worm gear 354. Both ends of the worm 357 are rotatably sleeved on the inner side of the two protrusions. One end of the worm 357 passes through the protrusion and connects with one end of the rotary drive rod 36. A threaded cylinder button 356 is fixedly connected to the inner wall of the cylindrical ring wall 353. A threaded post 355 is threadedly sleeved in the inner cavity of the threaded cylinder button 356. The bottom end of the threaded post 355 is fixedly connected to the top of the sliding block 32.

[0026] In use, the worm gear 357 is rotated by the rotary drive rod 36. The worm gear 357 and the worm wheel 354 mesh, causing the worm wheel 354 to rotate. The worm wheel 354 drives the cylinder ring wall 353 to rotate, which in turn drives the threaded cylinder button 356 to rotate. The threaded cylinder button 356 and the threaded column 355 are threaded together, allowing the threaded column 355 to rise and fall, which in turn drives the sliding block 32 to rise and fall. By utilizing the characteristics of the worm wheel 354 and the worm gear 357, the sliding block 32 can be controlled to rise and fall and then locked.

[0027] Reference Figure 4 The rotary drive rod 36 includes a central column 361, with two grooves inside the central column 361. Two inner sliders 362 are slidably sleeved in the two grooves. Two side columns 363 are fixedly connected to the outer ends of the two inner sliders 362. The outer ends of the two side columns 363 extend through the outside of the central column 361 and are connected to an end connecting cylinder 364. The end connecting cylinder 364 is fixedly connected to the worm gear 357.

[0028] Rotating the central column 361 can drive the two inner sliders 362 to rotate. The rotation of the inner sliders 362 drives the side column 363 to rotate. With the connection effect of the end connecting cylinder 364, the rotation of the worm gear 357 can be controlled. By setting the inner sliders 362 to slide in the column groove through this mechanism, the rotary drive rod 36 as a whole has a telescopic effect, which can be adapted to the adjustment of the distance between the fixed base 1 and the sliding base 2.

[0029] Reference Figure 4 The diameter of the inner slider 362 is larger than the diameter of the side column 363, and the diameter of the groove of the middle column 361 is adapted to the diameter of the inner slider 362.

[0030] This setting ensures that the inner slider 362 has an anti-detachment effect within the groove of the central column 361.

[0031] Reference Figure 4 The inner slider 362 is set as a polygon, and the shape of the groove of the central column 361 is adapted to the shape of the inner slider 362.

[0032] This setting prevents the inner slider 362 from spinning within the groove of the central column 361.

[0033] Reference Figure 5 The transmission rod assembly 4 includes two L-shaped fixing plates 41. The inner wall of the L-shaped fixing plate 41 has two rotating holes. Rotary cylinder 1 42 and rotary cylinder 2 43 are respectively rotatably sleeved in the two rotating holes. Rotary cylinder 1 42 and rotary cylinder 2 43 are connected by bevel gear meshing group 44. The two rotary cylinders 1 42 in the rotating holes of the two L-shaped fixing plates 41 are respectively fixedly connected to the side wall of the rotating drive rod 36 of the two pressure roller columns 3. The inner wall of the two rotary cylinders 2 43 in the rotating holes of the two L-shaped fixing plates 41 is fixedly connected to the connecting rod 45.

[0034] When one rotary drive rod 36 rotates, it can cause one rotary cylinder 42 to rotate. Under the transmission action of the bevel gear meshing group 44, it can cause another rotary cylinder 43 to rotate. Through the connection of the connecting rod 45, it can control the rotation of another rotary cylinder 43 on the other L-shaped fixed plate 41. Similarly, under the transmission action of the other bevel gear meshing group 44, the rotary cylinder 42 on the other L-shaped fixed plate 41 can drive the other rotary drive rod 36 to rotate.
