Description

Technical Field

[0001] The present invention relates to the technical field of battery core manufacturing, and in particular to a complete winding machine for cutting special-shaped pole pieces of button-type batteries. Background Art

[0002] The cutting-type special-shaped pole piece button cell winding machine is a battery production equipment, mainly used for winding and assembling battery pole pieces. This equipment uses a cutting process to accurately cut pole pieces of different shapes and assemble them into batteries quickly and accurately.

[0003] This type of equipment typically consists of a cutting machine, a winding machine, and an assembly machine, enabling automated production and significantly improving production efficiency and product quality. This cutting and forming machine for button-type batteries with special-shaped pole pieces is widely used for winding cylindrical batteries and Bluetooth batteries, and is an essential piece of equipment in modern battery production lines.

[0004] For example, the Chinese patent with publication number CN221239652U discloses a winding device for button battery production, which belongs to the field of battery production technology and includes a right-angle mounting plate, the upper and lower ends of one side of the right-angle mounting plate are respectively rotatably mounted with a positive electrode unwinding shaft and a negative electrode unwinding shaft, the upper and lower ends of one side of the right-angle mounting plate are respectively rotatably mounted with a first diaphragm shaft and a second diaphragm shaft, and the middle of the other side of the right-angle mounting plate is rotatably mounted with a pressure roller assembly. First, the elastic rods in each group move the correction arc plate outward so that it always fits the outside of the positive electrode unwinding roller and the negative electrode unwinding roller, effectively assisting the alignment of the electrode sheets. Then, a correction frame is fixedly installed between the ends of the two push rods inside the alignment frame, so that the positive and negative electrode sheets and the other ends of the two groups of diaphragms can be aligned under the action of external force. Then, the right-angle trapezoidal blocks are wide in and narrow out, and the height of the right-angle trapezoidal blocks is much larger than the thickness of the battery stack, so that the stacked multi-layer materials can be corrected again to avoid the phenomenon of protruding electrode sheets at both ends of the material layer.

[0005] However, the above devices still have some shortcomings in actual use:

[0006] 1. The existing winding methods are mostly manual winding or semi-automatic winding of electrodes. However, manual winding and semi-automatic winding equipment have low efficiency and low precision. The existing button-type winding equipment on the market is complicated to operate and needs to pass through multiple mechanisms before winding, causing the electrode to deviate during movement, resulting in low accuracy of the battery cell during winding.

[0007] 2. Secondly, the existing equipment has a complex structural design and dense layout. When winding the positive and negative electrodes of the battery, manual control of the loading of the positive and negative electrodes is required, which can easily lead to damage to the electrodes due to operational errors during loading. In addition, manual loading usually reserves a lot of time to operate the electrode loading to ensure the safety of the electrodes, which will lead to a slow loading speed and ultimately affect the preparation of the battery.

[0008] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing battery winding equipment. Summary of the Invention

Detailed implementation manners

[0067] The following further elaborates on this application in conjunction with the attached Figures 1-20 drawings.

[0068] The embodiment of this application discloses a complete winding machine for cut-off special-shaped electrode sheet button batteries.

[0069] For special-shaped cut-type electrodes, the existing winding methods are mostly manual winding or semi-automatic winding. Manual winding and semi-automatic winding equipment have low efficiency and low precision. The existing button-type winding equipment on the market is complicated to operate and needs to pass through multiple mechanisms before winding, causing the electrode to deviate during movement, resulting in low battery cell precision during winding; and the structural design is complex and the layout is dense, making equipment replacement and debugging difficult and time-consuming, which seriously affects production efficiency; in addition, there are too many components on the unloading end mechanism, resulting in a large layout of the entire equipment.

[0070] Secondly, the existing equipment has a complex structural design and dense layout. When winding the positive and negative electrodes of the battery, manual control of the loading of the positive and negative electrodes is required, which can easily lead to damage to the electrodes due to operational errors during loading. In addition, in order to ensure the safety of the electrodes, manual loading usually reserves a lot of time to operate the electrode loading, which will result in a slow loading speed and ultimately affect the preparation of the battery.

[0071] In order to solve the problems existing in the prior art, the present application proposes a complete equipment for winding button-type batteries with cut-off special-shaped pole pieces.

[0072] Example 1:

[0073] See Figure 1 and Figure 2 As shown, the cutting-type special-shaped electrode button battery winding machine includes a frame substrate 1, on which are installed a electrode loading mechanism 10, a electrode feeding mechanism 20, a diaphragm unwinding assembly 30, a electrode winding assembly 40, a diaphragm pressing and cutting assembly 50, a gluing assembly 60, a winding and picking assembly 70, a blanking assembly 80, a multi-station rotary disk assembly 90, a battery cell hot hole assembly 91, a short circuit test assembly 92 and a battery cell conveying assembly 93, characterized in that: the electrode loading mechanism 10 includes a material box assembly 100 installed on the frame substrate 1, a material box lifting assembly 110, a robot grasping assembly 120, a electrode return assembly 130, a first dust suction assembly 140 and an empty material box recovery assembly 150.

[0074] The material box assembly 100 is used to place the electrode material box 1001.

[0075] The magazine lifting assembly 110 is disposed below the magazine assembly 100 and is used to lift the magazine to a preset height.

[0076] The empty material box recovery assembly 150 is installed on one side of the material box assembly 100 and is used to recover the empty electrode material box 1001.

[0077] The electrode return assembly 130 is installed on one side of the magazine assembly 100. A first preset placement position for the electrode is set on one side of the electrode return assembly 130. The electrode return assembly 130 is used to complete the first positioning of the positive and negative electrode sheets.

[0078] See Figure 3 、 Figure 4 and Figure 5 As shown, the robot grasping assembly 120 is installed above the material box assembly 100, and is used to grasp the pole pieces from the pole piece material box 1001 and place them on the pole piece return assembly 130, and to place the empty pole piece material box 1001 from the material box assembly 100 into the empty material box recovery assembly 150.

[0079] The first dust collecting assembly 140 is installed on one side of the pole piece correcting assembly 130 and is used to absorb the pole piece dust on the pole piece correcting assembly 130 .

[0080] During the specific implementation process, the positive and negative electrode materials of the button battery to be processed are first placed in the corresponding material box assembly 100 in sequence, and then the material box lifting assembly 110 transports them to the specified preset height and preset position, and then the robot grasping assembly 120 moves.

[0081] Grab the electrode pieces into the interior of the magazine assembly 100 and place them in sequence. After the robot grasping assembly 120 completes its work, the interior of the magazine assembly 100 is filled with a specified amount of electrode pieces.

[0082] During the process of the electrode being conveyed to the material box assembly 100, the electrode correction assembly 130 adjusts the position of the electrode to ensure the accuracy of the electrode position and prevent the electrode from being offset and falling during the conveying process. At the same time, it can also ensure that the electrode is smoothly placed in the material box assembly 100 to avoid the electrode being skewed and unable to be quickly loaded into the material box assembly 100.

[0083] After the pole piece is positioned by the pole piece correcting assembly 130, the first dust suction assembly 140 starts to work. The first dust suction assembly 140 cleans the dust on the pole piece and cleans the dust and powder on the pole piece to prevent the dust on the upper end from remaining in the material box assembly 100, causing it to accumulate at the corners of the material box assembly 100 and be difficult to clean.

[0084] When all the pole pieces in the material box assembly 100 are wound and processed, the material box assembly 100 is in an empty box state. At this time, the empty material box recovery assembly 150 works to recycle the empty material box and at the same time transport the newly loaded product in the material box to the specified height for subsequent pole piece winding processing operations.

[0085] After a specified amount of electrodes are loaded into the magazine assembly 100 , the electrode feeding mechanism 20 is started to sequentially convey the electrodes loaded in the magazine assembly 100 to a specified processing area for winding operations.

[0086] See Figure 6As shown, the electrode feeding mechanism 20 includes a material taking robot assembly 200 , a material feeding and correcting assembly 210 , a sheet pressing assembly 220 and a second dust collecting assembly 230 installed on the frame base plate 1 .

[0087] The material picking robot assembly 200 is used to grab the electrode from the first preset placement position and place it at the second preset placement position;

[0088] The feeding and correcting assembly 210 includes a pole piece correction and positioning unit 211, a feeding unit 212 and a correcting unit 213 installed on the frame base plate 1. A second preset placement position is set on one side of the pole piece correction and positioning unit 211. The pole piece correction and positioning unit 211 is used to perform a second positioning of the pole piece at the second preset placement position. The feeding unit 212 is used to feed the pole piece to the pole piece winding assembly 40 for winding. The correcting unit 213 is used for correcting the pole piece during the winding process; the second dust suction assembly 230 is used to absorb dust on the pole piece.

[0089] The pressing assembly 220 is used for the smooth transportation of the pole pieces.

[0090] The second dust collecting assembly 230 is used to collect dust on the pole piece.

[0091] During the specific implementation process, after a large number of electrodes are filled in the material box, the material picking robot assembly 200 is started, and the material picking robot assembly 200 moves to the first preset placement position, and then adsorbs the electrodes in the material box assembly 100 by vacuum adsorption, and then transports them to the second preset placement position.

[0092] During this process, the feeding correction component corrects the position of the moving electrode to ensure that the two sides of the electrode can remain aligned during the winding process; at the same time, the pressing component 220 continuously presses down the electrode during the correction process to ensure the stability of the electrode. Similarly, the second dust collection component 230 adsorbs and cleans the dust on the surface of the electrode during the movement to ensure the neatness of the electrode before winding, and prevents the dust on the electrode from damaging the film that plays an isolating role during the winding process.

[0093] Replay Figure 1 and Figure 2 As shown, the membrane unwinding assembly 30 is used to place the membrane required for winding.

[0094] The electrode winding assembly 40 is used to wind the electrode and the diaphragm delivered by the electrode feeding mechanism 20 into a battery cell and deliver it to the next process.

[0095] The diaphragm cutting assembly 50 is used to cut the diaphragm and assist in the winding and gluing operations.

[0096] The adhesive component 60 is used to apply the termination adhesive to form a complete battery cell.

[0097] The winding and taking assembly 70 is used to remove the finished battery cells from the glue sticking assembly 60 and transport them to the next process.

[0098] The unloading assembly 80 is used to transfer the battery cells delivered from the winding and picking assembly 70 to the multi-station rotating disk assembly 90.

[0099] The multi-station rotary disk assembly 90 includes a turntable mounted on a frame base plate 1, and N equally spaced clamp cylinders for clamping battery cells are arranged on the outer sides of the turntable. The multi-station rotary disk assembly 90 is used to intermittently rotate the battery cells to perform battery cell hot hole and short circuit testing operations.

[0100] The battery cell punching assembly 91 is used to punch holes in the battery cells.

[0101] The short-circuit test assembly 92 performs a short-circuit test on the battery cell.

[0102] The battery cell conveying assembly 93 is used to convey the battery cells conveyed by the multi-station rotary disk assembly 90 to the terminal battery cell collection area.

[0103] During the specific implementation process, when the electrode is transported to the second preset placement position, the diaphragm unwinding assembly 30 is started and begins to release the diaphragm outward to ensure that the diaphragm also moves to the second preset placement position where the electrode is about to arrive, and the diaphragm is located below the electrode.

[0104] Then the electrode winding assembly 40 is started and begins to wind the electrode and the diaphragm together. It should be noted that there are two groups of electrode sheets in the present application, one group is the positive electrode sheet and the other group is the negative electrode sheet; a layer of diaphragm is placed under the positive electrode sheet, and a layer of diaphragm is also provided under the negative electrode sheet. When the two groups of electrode sheets and the two groups of diaphragms are wound together, the positive electrode sheet and the negative electrode sheet can be effectively isolated to avoid contact between the two and cause a short circuit in the button battery.

[0105] When the electrode is finished winding, the diaphragm pressing and cutting assembly 50 is triggered, and the diaphragm pressing and cutting assembly 50 cuts off the diaphragm in time, and performs the final winding on the small section of the diaphragm that is cut off but still reserved; then the glue sticking assembly 60 is started, and the glue is pasted on the small section of the diaphragm at the end, and the diaphragm and the electrode are adhered and wrapped together to form a spiral cylindrical structure.

[0106] Subsequently, the winding and picking assembly 70 transports the finished battery cells that have been glued to the next process, and transports them to the multi-station rotary disk assembly 90 through the unloading assembly 80. The multi-station rotary disk assembly 90 then performs intermittent battery cell hot-hole and short-circuit testing on the finished battery cells to ensure the quality of the battery cells is intact.

[0107] Subsequently, the short-circuit test component 92 is used to perform a short-circuit test on the battery cells that have been perforated to detect the quality of the battery cells. If the quality of the battery cells is qualified, they are transported to the battery cell collection point at the end through the battery cell conveying component 93; if the quality of the battery cells is unqualified, they are transported to the battery cell repair point for battery cell repair and inspection through the battery cell conveying component 93.

[0108] See Figure 8 As shown, the multi-station rotary disk assembly 90 includes a turntable 900 mounted on a frame base plate 1, and N equally spaced clamp cylinders 903 for clamping battery cells are arranged on the outer sides of the turntable 900. The multi-station rotary disk assembly 90 is used to intermittently rotate the battery cells to perform battery cell hot hole and short circuit testing operations.

[0109] The multi-station rotary disc assembly 90 further includes a rotary joint 901 connected to the middle of the rotary disc 900 , and blanking clamps 902 are provided at equal intervals in the circumferential direction of the rotary disc 900 , and the blanking clamps 902 are connected to the clamp cylinder 903 .

[0110] See Figure 9 As shown, the short circuit test component 92 includes a slide cylinder 920 arranged on the frame substrate 1, a test frame 921 on the output end of the slide cylinder 920, and two symmetrically distributed test clips 922 are provided on the test frame 921, and a test line connection position is provided on the opposite side of the two test clips 922.

[0111] The detection frame 921 and the test clamp 922 are controlled to move by the slide cylinder 920, so that the two test clamps 922 clamp the battery cell of the product, move it to the test line connection position, connect the test line to it and test it. If it passes the test, it will be transported to a unified collection point.

[0112] Example 2:

[0113] In Example 1, the electrode loading mechanism 10 is used to load the electrode into the electrode material box 1001, and then the empty material box recovery component 105 can be used to recover the material box; in order to ensure the efficiency of product winding processing, the present application also proposes a device that automatically switches the hole material box, which can be replaced to ensure the efficiency of electrode transportation.

[0114] The feeding assembly 3 proposed in the present application can also replace the electrode feeding mechanism 10 of the first embodiment to realize the automatic and continuous feeding of the electrode.

[0115] Reference Figure 10 and Figure 11 As shown, the complete equipment for winding button-type batteries with cut-off special-shaped pole pieces includes a frame base plate 1, which is placed on the ground and is used to carry the raw materials required for winding the button-type batteries. An equipment box 2 is provided on the frame base plate 1.

A square slot for moving the material box 30 is opened on the equipment box 2.

[0118] It should be noted that the function of the material box 30 is to load the special-shaped electrode pieces so that the special-shaped electrode pieces can be evenly arranged in the material box 30 , and the material-taking robot assembly 200 automatically transports the special-shaped electrode pieces in the material box 30 .

[0119] Reference Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, it is a structural schematic diagram of conveying the material box 30 in this embodiment; specifically, the material box conveying module 31 includes two groups of conveyor belts 310 distributed at right angles, and both conveyor belts 310 are provided with conveying rollers 311 distributed in a rectangular shape and rotatably arranged on the inner wall of the equipment box 2, and the horizontally distributed conveyor belt 310 is connected to the first bevel gear 312, and the first bevel gear 312 is meshed with the second bevel gear 313, and a linkage belt 314 is connected between the back side of the second bevel gear 313 and the conveying roller 311 on the vertically distributed conveyor belt 310.

[0120] The conveying roller 311 sleeved on the vertically distributed conveying belt 310 is connected to a conveying motor 315 , and the conveying motor 315 is installed on the inner wall of the equipment box 2 through a motor base.

[0121] The material box 30 is placed on the conveyor belt 310 .

[0122] The material box conveying module 31 in the present application can automatically convey the material box 30, and the material box 30 can also be automatically loaded to perform material loading operations on the electrode pieces in the material box 30.

[0123] Start the conveyor motor 315. The conveyor motor 315 controls the uniform movement of the material box 30 at its upper end through the conveyor belt 310. After the material box 30 moves to the position of the square groove in the equipment box 2, the controller 6 controls the material box 30 to pass through the square groove of the equipment box 2, so that the material box 30 moves to the preset position directly above the frame substrate 1. Subsequently, the picking manipulator assembly 200 picks up the special-shaped pole pieces in the material box 30 and conveys the special-shaped pole pieces. After the winding operation of the special-shaped pole pieces in the material box 30 is completed, the controller 6 controls the material box 30 to return to the equipment box 2 again. Then, the conveyor motor 315 in the equipment box 2 starts, controlling other material boxes 30 loaded with special-shaped pole pieces on the conveyor belt 310 to reach the square groove of the equipment box 2, and making them extend and retract from the square groove, repeating the above feeding operation; after the empty material box 30 moves to the designated feeding area, the operator places the special-shaped pole pieces into the material box 30.

[0124] Furthermore, the continuous feeding of the special-shaped pole pieces is realized, the downtime for material change is reduced, and the production efficiency is improved.

[0125] Refer to Figure 16 、 Figure 17 and Figure 18 As shown in

[0126] That is, the schematic structural diagram of the material box 30 in the present application; specifically, the material box 30 is composed of two right-angle slides 300 distributed at right angles. On one side where the two right-angle slides 300 face each other, there is an adjusting spring 307. And on both sides in the length direction of the two right-angle slides 300, there are symmetrically hinged sealing doors 301. The sealing doors 301 are telescopic structures. There are U-shaped plates 302 clamped and installed on the two right-angle slides 300. Horizontal chutes are provided on the U-shaped plates 302 in a horizontal distribution. There are fixed columns 303 in the horizontal chutes of the two U-shaped plates 302. There are two pairs of limiting nuts 304 for clamping between the fixed columns 303 and the U-shaped plates 302. The limiting nuts 304 are threadedly connected with the fixed columns 303; A limiting rope 305 is slidably penetrated between the two fixed columns 303.

[0127] It should be noted that the mutually screwed parts of the fixed column 303 and the compression screw sleeve 306 are mutually matching inclined structures, and the end of the fixed column 303 close to the compression screw sleeve 306 will squeeze and limit the limiting rope 305 under the extrusion of the compression screw sleeve 306.

[0128] The material box 30 can adjust its size, can better adapt to the storage requirements of different pole pieces, thus making the best use of the storage space, reducing the occupied area of the pole pieces, and at the same time can effectively improve the stability of the pole pieces in the material box 30. Further, it can also reduce the replacement of the material box 30, improve the use efficiency of the material box 30, and reduce the cost consumption.

[0129] participate Figure 19 and Figure 20 As shown, when winding operations are performed on pole pieces of different sizes, it is first necessary to adjust the size of the material box 30, rotate the tightening spiral sleeve 306 to move it away from the fixed column 303, and then the limiting rope 305 can move according to the size of the pole piece, and then push the two right-angle slides 300 to move to ensure that the pole piece can be placed just into the material box 30, and then rotate the tightening spiral sleeve 306 to straighten the limiting rope 305, and ensure that the two right-angle slides 300 are limited and cannot be adjusted.

[0130] At this time, the size of the material box 30 can be adjusted according to the different sizes of pole pieces, ensuring that the material box 30 and the entire equipment can perform winding operations for pole pieces of different sizes, greatly improving the applicability of this application.

[0131] One end of the fixing column 303 that is screwed to the compression screw sleeve 306 is provided with spacing grooves at equal intervals, and the part of the fixing column 303 with the spacing grooves tends to gather inward under the extrusion of the compression screw sleeve 306, and the part where the fixing column 303 and the compression screw sleeve 306 cooperate is an inclined structure.

[0132] The material box 30 of the present application can be adjusted in size to better adapt to the storage requirements of different electrodes, thereby maximizing the use of storage space and reducing the area occupied by the electrodes. At the same time, it can also effectively improve the stability of the electrodes in the material box 30, and further reduce the replacement of the material box 30, improve the utilization efficiency of the material box 30, and reduce cost consumption.

[0133] The present invention can also transport pole pieces of different shapes, ensuring the applicability of the equipment.

[0134] When the material box 30 moves to the designated position, the electrode pieces loaded therein can be transported, as shown below.

[0135] Replay Figure 7 As shown, the material picking robot assembly 200 includes a first linear translation module 2006 installed on the frame base plate 1, and the first linear translation module 2006 is driven and connected to a swing arm module. The swing arm module includes a swing arm drive motor 2005 that is slidingly connected to the first linear translation module 2006 and a swing arm bracket assembly 2000 that is transmission-connected to the swing arm drive motor 2005. The swing arm bracket assembly 2000 includes a swing arm upper bracket 2001 connected to the output shaft of the swing arm drive motor 2005 and a swing arm lower bracket 2002 that is slidingly connected to the swing arm upper bracket 2001. The swing arm upper bracket 2001 is installed with a lifting cylinder 2003 that drives the swing arm lower bracket 2002 to move relative to the swing arm upper bracket 2001; the swing arm lower bracket 2002 is installed with multiple vacuum suction nozzles 2004.

[0136] When it is necessary to convey the electrode pieces in the material box 30, the first linear translation module 2006 controls the swing arm drive motor 2005 and the swing arm bracket assembly 2000 to move to the position of the material box 30, and then the swing arm drive motor 2005 is started, and the swing arm drive motor 2005 controls the swing arm upper bracket 2001 and the swing arm lower bracket 2002 to rotate, so that the multiple vacuum suction nozzles 2004 on the swing arm lower bracket 2002 are against the electrode pieces on the material box 30, and then the multiple vacuum suction nozzles 2004 adsorb the electrode pieces in the material box 30, and then the swing arm drive motor 2005 is started again, and the swing arm drive motor 2005 rotates so that the adsorbed electrode pieces are distributed parallel to the length direction of the first linear translation module 2006, and then the first linear translation module 2006 controls the swing arm lower bracket 2002 with the electrode pieces adsorbed to move toward the direction of the winder until the electrode pieces on the swing arm lower bracket 2002 move to the specified position.

[0137] However, it should be noted that two groups of material boxes 30 are provided on the frame substrate 1 of the present application, one group of material boxes 30 is specifically used to load positive electrode sheets, and the other group of material boxes 30 is specifically used to load negative electrode sheets. A diaphragm is provided between the two positive and negative electrode sheets for winding operations.

[0138] Furthermore, the lengths of pole pieces of different sizes are different, so the vacuum nozzle 2004 needs to be position-adjusted. The two sides of the vacuum nozzle 2004 are limited on the swing arm lower bracket 2002 by clamping nuts, and the strip slide grooves on the swing arm lower bracket 2002 can be used for position adjustment of the vacuum nozzle 2004. If the pole piece size required for winding operation is small, the spacing between the vacuum nozzles 2004 can be adjusted to be smaller; conversely, if the pole piece size is large, the spacing between the vacuum nozzles 2004 can be adjusted to be larger.

[0139] During work: the first step is to prepare the operation, place the electrodes to be processed into the material box 30 inside the equipment box 2 in turn, and then start the conveying motor 315. The conveying motor 315 controls the material box 30 to move at a uniform speed, so that the material box 30 with the electrode installed moves to the square slot of the equipment box 2.

[0140] Step 2: When the material box 30 moves to the vicinity of the square slot of the equipment box 2 and forms a straight line with it, the vacuum suction cup 42 on the controller 6 will move toward the equipment box 2 until the vacuum suction cup 42 is adsorbed to the material box 30, and then the material box 30 is controlled to move to the outside of the equipment box 2 until the equipment box 2 extends to the specified position.

[0141] Step 3: After the material box 30 moves to the designated position, the electrode pieces inside it need to be transported. Multiple vacuum nozzles 2004 adsorb the electrode pieces in the material box 30, and then the swing arm drive motor 2005 is started. The swing arm drive motor 2005 rotates so that the adsorbed electrode pieces are distributed parallel to the length direction of the first linear translation module 2006. Then the first linear translation module 2006 controls the swing arm lower bracket 2002 with the electrode pieces adsorbed thereon to move toward the direction of the winder until the electrode pieces on the swing arm lower bracket 2002 move to the designated position.

[0142] Step 4: There are two groups of material boxes 30 on the frame base plate 1, one group of material boxes 30 is specifically used to load positive electrode sheets, and the other group of material boxes 30 is specifically used to load negative electrode sheets. The positive electrode sheets and the negative electrode sheets are transported synchronously through the feeding assembly 4.

[0143] Step 5: When winding electrodes of different sizes, it is first necessary to adjust the size of the material box 30, rotate the tightening spiral sleeve 306 to move it away from the fixed column 303, and then the limiting rope 305 can move. Then, according to the size of the electrode, push the two right-angle slides 300 to move to ensure that the electrode can be placed just into the material box 30, and then rotate the tightening spiral sleeve 306 to straighten the limiting rope 305 to ensure that the two right-angle slides 300 are limited and cannot be adjusted.

[0144] At this time, the size of the material box 30 can be adjusted according to the different sizes of pole pieces, ensuring that the material box 30 and the entire equipment can perform winding operations for pole pieces of different sizes, greatly improving the applicability of this application.

[0145] Step 5: After the electrode is transported to the designated position, the electrode winding assembly 40 is started and begins to wind the electrode and the diaphragm together. It should be noted that there are two groups of electrode sheets in this application, one group is the positive electrode sheet and the other group is the negative electrode sheet; a layer of diaphragm is placed under the positive electrode sheet, and a layer of diaphragm is also provided under the negative electrode sheet. When the two groups of electrode sheets and the two groups of diaphragms are wound together, the positive electrode sheet and the negative electrode sheet can be effectively isolated to avoid contact between the two and cause a short circuit in the button battery.

[0146] Step 6: When the electrode is finished winding, the diaphragm pressing and cutting assembly 50 is triggered, and the diaphragm pressing and cutting assembly 50 cuts off the diaphragm in time, and performs the final winding on the small section of the diaphragm that is reserved after the cut; then the glue sticking assembly 60 is started, and the glue is pasted on the small section of the diaphragm at the end, and the diaphragm and the electrode are adhered and wrapped together to form a spiral cylindrical structure.

[0147] Step 7: The winding and picking assembly 70 then transports the finished battery cells that have completed gluing to the next process, and transports them to the multi-station rotary disk assembly 90 through the unloading assembly 80. The multi-station rotary disk assembly 90 then performs intermittent battery cell hot-hole and short-circuit tests on the finished battery cells to ensure the quality of the battery cells is intact.

[0148] Step 8: Then, the short-circuit test component 92 is used to perform a short-circuit test on the battery cells that have been perforated to detect the quality of the battery cells. If the quality of the battery cells is qualified, the battery cells are transported to the battery cell collection point at the end through the battery cell conveying component 93; if the quality of the battery cells is unqualified, the battery cells are transported to the battery cell repair point for battery cell repair and inspection through the battery cell conveying component 93.

[0149] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
