Description

Technical Field

[0001] This utility model belongs to the field of lithium-ion battery processing, specifically relating to a tab-folding tooling for a full-tab winding core. Background Technology

[0002] With the rapid development of the new energy industry, cylindrical lithium-ion batteries have become the main choice for many industries such as automobiles and power tools. In the production of all-tab cylindrical batteries, one of the processes is tab bending, which is a key pretreatment process before current collector welding. The bending of the positive and negative tabs is done using two separate pieces of equipment, which are not interchangeable. Utility Model Content

[0003] To address the shortcomings described in the prior art, this utility model provides a tab-folding fixture for all-pole core windings, applicable to both positive and negative tab folding, requiring only switching installation.

[0004] The technical solution adopted in this utility model is as follows: A tab-folding fixture for a full-tab winding core includes a tab-folding height adjustment mechanism and a tab-folding mechanism. The tab-folding mechanism includes a tab-folding mounting base, a tab-folding reciprocating movement structure, a negative tab-folding structure, and a positive tab-folding structure. The tab-folding mounting base is inclinedly mounted on the moving part of the tab-folding height adjustment mechanism. The tab-folding reciprocating movement structure is mounted on the tab-folding mounting base, and the reciprocating movement direction of the tab-folding reciprocating movement structure is parallel to the inclination direction of the tab-folding mounting base. The moving part of the tab-folding reciprocating movement structure is provided with a positive tab-folding connection position and a negative tab-folding connection position. When the positive tab is folded, the positive tab-folding structure is connected to the positive tab-folding connection position, and the negative tab-folding connection position is idle. When the negative tab is folded, the negative tab-folding structure is connected to the negative tab-folding connection position, and the positive tab-folding connection position is idle. The tab-falling height adjustment mechanism can change the overall height of the tab-falling mechanism, thereby changing the tab-falling depth. The tab-falling mechanism is directly set with two workstations. When the positive tab is to be fallen, the positive tab-falling structure can be installed to start the operation. When the negative tab needs to be fallen, the negative tab-falling structure can be installed in place. One device can be compatible with the installation of two falling devices, improving the applicability of the device and reducing the complexity of the tab-falling equipment.

[0005] In a preferred embodiment of this invention, both the electrode lug tilting height adjustment mechanism and / or the tilting reciprocating movement structure are equipped with a stroke adjustment structure. The stroke adjustment structure limits the movement stroke of the electrode lug tilting height adjustment mechanism and the tilting reciprocating movement structure.

[0006] In a preferred embodiment of this utility model, the stroke adjustment structure includes a micrometer, a limit adjustment block, and a limit stop. The micrometer is connected to the moving part of the tab tilt height adjustment mechanism or the tilt reciprocating movement structure, and the micrometer is parallel to the moving part. The tip of the micrometer is connected to the limit adjustment block. The limit stop is connected to the fixed part of the tab tilt height adjustment mechanism or the tilt reciprocating movement structure. The moving limit adjustment block abuts against the limit stop to achieve limiting. When stroke adjustment is required, the limit adjustment block is released, allowing the micrometer to change the extension length of the tip. Then, the limit adjustment block is fixed to the tip. The distance between the limit adjustment block and the limit stop is the maximum stroke distance. The stroke range of the tab tilt height adjustment mechanism and the tilt reciprocating movement structure is set according to the preset stroke distance.

[0007] In a preferred embodiment of this utility model, the moving part of the reciprocating collapsing structure is provided with a collapsing base plate, which has a positive electrode collapsing connection position and a negative electrode collapsing connection position. The positive electrode collapsing connection position is located on the side of the negative electrode collapsing connection position. The negative electrode collapsing structure includes a negative electrode collapsing push block, which is adjustablely mounted on the negative electrode collapsing connection position. The head of the negative electrode collapsing push block has a collapsing slope, and the setting direction of the negative electrode collapsing push block is parallel to the tilting direction of the collapsing mounting base plate. The negative electrode collapsing push block can also be called a sloping push block. Because the negative electrode is relatively hard, a collapsing slope is used for collapsing. Moreover, the collapsing slope of the negative electrode collapsing push block is parallel to the electrode end face of the core. Because the collapsing mounting base plate itself is tilted, the negative electrode collapsing push block reciprocates radially along the core to achieve collapsing. The negative electrode collapsing push block is aligned with the center of the electrode.

[0008] In a preferred embodiment of this utility model, the positive electrode tab folding structure includes a positive electrode tab folding push block. The positive electrode tab folding push block includes a folding arm and a folding head. The folding arm is adjustablely mounted on the positive electrode tab folding connection position, and its orientation is perpendicular to the tilt direction of the folding mounting base. The folding head is located at the free end of the folding arm, and its orientation is parallel to the tilt direction of the folding mounting base. The folding arm and folding head are L-shaped. The positive electrode tab folding push block can also be called a transverse push block. Because the positive electrode tab is relatively soft, the folding head can be used to fold it over.

[0009] As a preferred embodiment of this utility model, the positive electrode tab folding structure further includes a positive electrode tab folding moving guide assembly, which includes a guide moving plate, a guide base plate, a guide slider, a guide slide rail, a guide moving groove plate, and a moving cam. The guide moving plate is slidably mounted on the guide base plate, the guide slide rail is mounted on the lower end face of the guide moving plate, and the guide slider is mounted on the upper end face of the guide base plate. The guide slider cooperates with the guide slide rail, and the guide slide rail moves relative to the guide slider. Alternatively, the guide slide rail can be on the guide base plate, and the guide slider can be on the lower end face of the guide moving plate, as long as the guide moving plate can reciprocate relative to the guide base plate. A guide moving groove plate is mounted on the guide moving plate, and the moving cam is mounted on the positive electrode tab folding connection position via a rotating shaft, and the moving cam is located in the vertical groove of the guide moving groove plate. The folding arm is adjustablely mounted on the front side of the guide moving plate. The moving cam, under the action of the guide plate, will move up and down and roll within the vertical groove of the guide moving slot plate, driving the guide moving plate forward or backward; the guide moving plate with the positive electrode tab falling pusher moves forward and backward along the core radially, realizing the electrode tab falling over.

[0010] As a preferred embodiment of this utility model, the electrode ear tilting height adjustment mechanism includes a tilting height adjustment power component and a tilting height adjustment plate. The moving part of the tilting height adjustment power component moves vertically back and forth, and the moving part of the tilting height adjustment power component is connected to the tilting height adjustment plate. The inclined end face of the top of the tilting height adjustment plate is fixedly connected to the tilting mounting base plate.

[0011] As a preferred embodiment of this utility model, the electrode ear tilting height adjustment mechanism further includes a height guide structure. A height guide structure is provided on both the front and rear sides of the tilting height adjustment power component. The height guide structure includes a vertical track plate and a guide support plate. The guide support plate is slidably mounted on the vertical track plate, and the inclined end face of the top of the guide support plate is connected to the tilting mounting base plate.

[0012] As a preferred embodiment of this utility model, the guide support plate near the positive electrode tab is fixedly connected to the guide base plate.

[0013] As a preferred embodiment of this utility model, the tab tilting height adjustment mechanism is mounted on a base, and a core placement position is also provided on the base. The core placement position is provided with a core placement structure, which can rotate 360° in place to change the tilting position of the core tab.

[0014] This utility model's electrode tab tilting height adjustment mechanism can change the overall height of the electrode tab tilting mechanism, thereby changing the tilting depth of the electrode tab. The electrode tab tilting mechanism is used to complete the tilting work of the electrode tab. It directly sets two workstations. When tilting the positive electrode tab, the positive electrode tab tilting structure is installed and it can work. When tilting the negative electrode tab is required, the negative electrode tab tilting structure is installed in place. One device can be compatible with the installation of two tilting devices, improving the applicability of the device and reducing the complexity of the electrode tab tilting device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: A tooling for bending the tabs of a full-tab winding core, such as Figure 1-3 As shown, it includes a tab tilting height adjustment mechanism and a tab tilting mechanism.

[0025] The electrode tilting height adjustment mechanism is used to adjust the depth of electrode tilting, such as... Figure 4 As shown, it includes a lodging height adjustment power component 11, a lodging height adjustment plate 12, and a base 15. The lodging height adjustment power component 11 is mounted on the base 15. The moving part of the lodging height adjustment power component 11 moves vertically back and forth. The lodging height adjustment power component 11 adopts a lifting cylinder. The lifting cylinder is set vertically, and the piston rod of the lifting cylinder is connected to the lodging height adjustment plate 12. The top of the lodging height adjustment plate 12 is an inclined end face, which serves as a fixed connection position with the lodging mounting base plate 21 of the electrode lodging mechanism, so that the lodging mounting base plate 21 is set at an inclination.

[0026] To ensure the stable installation of the inverted mounting base 21, height guide structures are provided on both the front and rear sides of the inverted height adjustment power component 11 on the base 15. These height guide structures include a vertical track plate 13 and a guide support plate 14. The guide support plate 14 is slidably mounted on the vertical track plate 13, and the guide support plate 14 and the vertical track plate 13 are connected by a slider rail. The inclined end face of the top of the guide support plate 14 is connected to the inverted mounting base 21. The inverted mounting base 21 is supported by the two guide support plates and the inverted height adjustment plate together.

[0027] The electrode tipping height adjustment mechanism is equipped with a stroke adjustment structure, which includes a micrometer 31, a limit adjustment block 32, and a limit stop 33. The micrometer 31 is vertically mounted on the tipping height adjustment plate. The limit adjustment block is mounted on the tipping height adjustment plate through a hole and bolts, and is connected to the tip of the micrometer to prevent the micrometer from rotating. The limit stop 33 is located on the base 13, below the limit adjustment block. When the stroke needs to be adjusted, the limit adjustment block is released, and the micrometer can be operated to change the extension length of the tip. Then, the limit adjustment block is fixed to the tip. The distance between the limit adjustment block and the limit stop is the maximum stroke distance. According to the set stroke distance, the stroke range of the electrode tipping height adjustment mechanism and the tipping reciprocating movement structure 22 is set. The moving limit adjustment block 32 abuts against the limit stop 33 to achieve the limit.

[0028] The base is also equipped with a core placement position, which has a core placement structure that can rotate 360° in place to change the position of the core tabs.

[0029] like Figure 1-3As shown in Figure 5, the tab-falling mechanism includes a tab-falling mounting base plate 21, a tab-falling reciprocating movement structure 22, a negative tab-falling structure 23, and a positive tab-falling structure 24.

[0030] The reciprocating tilting structure 22 is mounted on the tilting mounting base plate 21. The reciprocating tilting structure 22 adopts a slide cylinder, and the reciprocating movement direction of the slide cylinder is parallel to the tilting direction of the tilting mounting base plate 21. The moving part of the slide cylinder is equipped with a tilting base plate 25, which is L-shaped. The tilting base plate 25 is provided with a positive electrode tab tilting connection position 221 and a negative electrode tab tilting connection position 222. The positive electrode tab tilting connection position 221 is located on the side of the negative electrode tab tilting connection position 222, that is, the positive electrode tab tilting connection position 221 is located at the protrusion of the L-shaped structure.

[0031] The reciprocating moving structure 22 is also equipped with a stroke adjustment structure, which includes a micrometer 31, a limit adjustment block 32, and a limit stop block 33. The micrometer 31 and the limit adjustment block are mounted on the reciprocating mounting base plate 21 and are in a fixed position. The limit stop block is mounted on the moving part of the reciprocating moving structure 22. The setting direction of the micrometer 31 is parallel to the moving part. The tip of the micrometer 31 is connected to the limit adjustment block 32.

[0032] Of course, the micrometer 31 and the limit adjustment block can also be installed on the moving part, and the limit stop block can be fixed. As long as the limit stop block and the limit adjustment block move relative to each other, this embodiment adopts the method of limit stop block movement.

[0033] When the stroke needs to be adjusted, loosen the limit adjustment block, and the micrometer can be operated to change the extension length of the ruler head. Then, fix the limit adjustment block to the ruler head. The distance between the limit adjustment block and the limit stop is the maximum stroke distance. Set the stroke range of the reciprocating movement structure 22 according to the set stroke distance.

[0034] The negative electrode tab folding structure 23 and the positive electrode tab folding structure 24 are mutually interfering components, so only one of them is installed during use. That is, when the positive electrode tab is folded, the positive electrode tab folding structure 24 is connected to the positive electrode tab folding connection position 221, and the negative electrode tab folding connection position 222 is idle; when the negative electrode tab is folded, the negative electrode tab folding structure 23 is connected to the negative electrode tab folding connection position 222, and the positive electrode tab folding connection position 221 is idle.

[0035] The negative electrode tab folding structure 23, as described above Figure 6As shown, the device includes a negative electrode tab folding pusher 231, which is adjustablely mounted on the negative electrode tab folding connection position 222. Specifically, a waist hole is provided on the folding substrate 25. The negative electrode tab folding pusher 231 is installed in place through the waist hole and bolts. The direction of the waist hole is perpendicular to the tilt direction of the folding mounting substrate. The waist hole is provided to adjust the position of the negative electrode tab folding pusher so that it can be aligned with the center of the core electrode tab. The direction of the negative electrode tab folding pusher 231 is parallel to the tilt direction of the folding mounting substrate 21, and the head of the negative electrode tab folding pusher 231 is provided with a folding slope. The negative electrode tab bending pusher 231 can also be called an inclined pusher. Because the negative electrode tab is relatively hard, a bending slope is used for bending. Moreover, the bending slope of the negative electrode tab bending pusher is parallel to the end face of the electrode tab of the winding core. Since the bending mounting base itself is inclined, the negative electrode tab bending pusher moves back and forth along the radial direction of the winding core to achieve bending. The negative electrode tab bending pusher is aligned with the center of the electrode tab.

[0036] like Figure 7 As shown, the positive electrode tab folding structure 24 includes a positive electrode tab folding pusher 241 and a positive electrode tab folding moving guide assembly. The positive electrode tab folding moving guide assembly includes a guide moving plate 242, a guide base plate 243, a guide slider 244, a guide slide rail 245, a guide moving groove plate 246, and a moving cam 247. The guide base plate 243 is fixedly connected to the guide support plate 14 near the positive electrode tab folding pusher 241. The guide moving plate 242 is slidably mounted on the guide base plate 243. A guide slide rail is installed on the lower end face of the guide moving plate, and a guide slider is installed on the upper end face of the guide base plate 243. The guide slider cooperates with the guide slide rail, and the guide slide rail moves relative to the guide slider. Alternatively, the guide slide rail can be on the guide base plate, and the guide slider can be on the lower end face of the guide moving plate, as long as the guide moving plate can reciprocate relative to the guide base plate.

[0037] A guide moving plate 246 is installed on the guide moving plate 242. A moving cam 247 is mounted on the positive electrode tab lying connection position 221 via a rotating shaft, and the moving cam 247 is located in the vertical groove of the guide moving plate 246. The positive electrode tab lying pusher 241 is adjustablely installed on the front side of the guide moving plate 242. The moving cam 247 is acted upon by the guide base plate 243 and will move up and down in the vertical groove of the guide moving plate, driving the guide moving plate forward or backward. The guide moving plate, along with the positive electrode tab lying pusher 241, moves forward and backward along the core radially, realizing the electrode tab being pushed down.

[0038] The positive electrode tab folding pusher 241 includes a folding arm 2411 and a folding head 2412. A guide plate 242 has a slotted hole. The folding arm 2411 is adjustablely mounted on the front side of the guide plate 242 via the slotted hole and bolts. The folding arm 2411 is perpendicular to the tilt direction of the folding mounting base 21. The folding head 2412 is located at the free end of the folding arm 2411, and its orientation is parallel to the tilt direction of the folding mounting base 21. The folding arm and folding head are L-shaped. The positive electrode tab folding pusher 241 can also be called a transverse pusher. Because the positive electrode tab is relatively soft, the folding head can be used to fold it over.

[0039] Depending on whether the positive or negative electrode tab collapses, choose to install either a positive or negative electrode tab collapse structure.

[0040] Before starting the bending operation, adjustments are required: After placing the core 4 in the rotating cup, adjust the limit position of the slide cylinder and the micrometer screw gauge so that the working surface of the positive or negative tab bending pusher is in contact with the end face of the core tab when the slide cylinder is extended and the lifting cylinder is retracted. Then retract the slide cylinder, and adjust the micrometer screw gauge and limit position of the lifting cylinder according to the required bending depth of the tab.

[0041] After debugging, both the lifting cylinder and the slide cylinder are in the retracted state. During operation, the slide cylinder extends (pushing the block to flatten the electrode tab) → the lifting cylinder extends (to prevent damage to the electrode tab) → the slide cylinder retracts → the lifting cylinder retracts → the core support cup rotates → the slide cylinder extends (pushing the block to flatten the electrode tab).

[0042] The core tabs are tilted to different heights by adjusting the micrometer of the lifting cylinder. The core tabs are tilted in different directions by switching between the oblique push block and the lateral push block. The tilting amount is adjusted by controlling the rotation angle of the core support cup during each tilt.
