Description

Technical Field

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

[0002] The cutting type special-shaped pole piece button battery winding machine is a kind of equipment used for producing batteries, mainly used for winding and assembling the pole pieces of batteries. The equipment adopts the cutting process, which can accurately cut pole pieces of different shapes and assemble the pole pieces into batteries quickly and accurately.

[0003] This type of equipment usually consists of cutting machines, winding machines, assembling machines and other parts, which can realize automated production and greatly improve production efficiency and product quality. The cutting type special-shaped pole piece button battery winding machine is widely used in the winding and forming of cylindrical batteries and Bluetooth batteries, and is one of the indispensable key equipment in modern battery production lines.

[0004] For example, a Chinese patent with publication number CN221239652U discloses a winding device for button cell production, which belongs to the field of battery production technology, including 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 rod of each group moves the correction arc plate outward to always fit the outside of the positive electrode unwinding roller and the negative electrode unwinding roller, effectively assisting the alignment of the electrode sheets, and 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, and then the right-angle trapezoidal block is wide in and narrow out, and the height of the right-angle trapezoidal block 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 equipment still has some shortcomings in actual use:

[0006] 1. The existing winding methods are mostly manual winding or semi-automatic winding of pole pieces, and the manual winding and semi-automatic winding equipment are inefficient and low in precision. The existing buckle winding equipment on the market is complicated to operate and needs to pass through multiple mechanisms before winding, causing the pole piece 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 a dense layout. When winding the positive and negative electrodes of the battery, manual control of the loading of the positive and negative electrode sheets is required, which can easily lead to damage to the electrode sheets due to operational errors during loading. In addition, manual loading usually reserves a lot of time to operate the electrode sheet loading in order to ensure the safety of the electrode sheets, which will result in a slow loading speed and ultimately affect the preparation of the battery.

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

[0067] The following is a further detailed description of the present application in conjunction with the attached Figure 1-Figure 20 drawings.

[0068] The embodiment of the present application discloses a cutting-type special-shaped electrode sheet button cell winding whole machine equipment.

[0069] For special-shaped cut-type pole pieces, the existing winding methods are mostly manual winding or semi-automatic winding of pole pieces, and the manual winding and semi-automatic winding equipment are inefficient and low in 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 pole piece to deviate during movement, resulting in low accuracy of the battery cell during winding; and the structural design is complex and the layout is dense, resulting in difficulties in equipment replacement and debugging, which is time-consuming and seriously affects production efficiency; in addition, there are too many components in the unloading end mechanism, resulting in a large layout of the entire equipment.

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

[0071] In order to solve the problems existing in the prior art, the present application proposes a cutting-type special-shaped pole piece button-type battery winding machine.

[0072] Embodiment 1:

[0073] See also Figure 1 and Figure 2 As shown, the cutting type special-shaped pole piece button battery winding machine equipment includes a frame substrate 1, on which are installed a pole piece loading mechanism 10, a pole piece feeding mechanism 20, a diaphragm unwinding assembly 30, a pole piece winding assembly 40, a diaphragm pressing and cutting assembly 50, a glue sticking assembly 60, a winding and taking assembly 70, a material unloading assembly 80, a multi-station rotating 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 pole piece 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 pole piece 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 pole piece material box 1001 .

[0075] The material box lifting assembly 110 is disposed below the material box assembly 100 and is used to lift the material box 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 piece alignment assembly 130 is installed on one side of the material box assembly 100 , and a first preset placement position for the electrode piece is provided on one side of the electrode piece alignment assembly 130 . The electrode piece alignment assembly 130 is used to complete the first positioning of the positive and negative electrode pieces.

[0078] See also Figure 3 , Figure 4 and Figure 5 As shown, the robot gripping assembly 120 is installed above the material box assembly 100, and is used to grab 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 suction assembly 140 is installed on one side of the pole piece correcting assembly 130 and is used to suck 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 material box assembly 100 and place them in sequence. After the robot grasping assembly 120 completes its work, a specified amount of electrode pieces are filled into the interior of the material box assembly 100.

[0082] During the process of the electrode piece being conveyed to the material box assembly 100, the electrode piece correction assembly 130 adjusts the position of the electrode piece to ensure the accuracy of the electrode piece position and prevent the electrode piece from being offset and falling during the conveying process. At the same time, it can also ensure that the electrode piece is smoothly placed in the material box assembly 100 to prevent the electrode piece from 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, and the first dust suction assembly 140 cleans the dust on the pole piece, cleans the dust and powder on the pole piece, and prevents 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, the material box assembly 100 is in an empty box state. At this time, the empty material box recovery assembly 150 works to recover the empty material box and at the same time transport the newly loaded product in the material box to a specified height for subsequent pole piece winding processing.

[0085] After a specified amount of pole pieces are loaded in the material box assembly 100, the pole piece feeding mechanism 20 is started to sequentially convey the pole pieces loaded in the material box assembly 100 to the specified processing area for winding operation.

[0086] See also Figure 6As shown, the pole piece 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 which are installed on the frame base plate 1 .

[0087] The material taking manipulator assembly 200 is used to grab the pole piece 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 alignment 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 alignment and positioning unit 211. The pole piece alignment and positioning unit 211 is used to perform a second positioning on 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 smooth transportation of the pole pieces.

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

[0091] During the specific implementation process, after a large number of electrode pieces 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 electrode pieces 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 assembly corrects the position of the moving pole piece to ensure that the two sides of the pole piece can remain aligned during the winding process; at the same time, the pressing assembly 220 continuously presses down on the pole piece during the correction process to ensure the stability of the pole piece. Similarly, the second dust suction assembly 230 adsorbs and cleans the dust on the surface of the pole piece during its movement to ensure the neatness of the pole piece before winding, and to prevent the dust on the pole piece from damaging the film that serves as an isolation 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 pole piece winding assembly 40 is used to wind the pole pieces and diaphragms conveyed by the pole piece feeding mechanism 20 into a battery cell and convey it to the next process.

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

[0096] The glue sticking assembly 60 is used to stick the termination glue to form a complete battery cell.

[0097] The winding and picking assembly 70 is used to take 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 conveyed by the winding and picking assembly 70 to the multi-station rotating disk assembly 90 .

[0099] The multi-station rotating disk assembly 90 includes a rotating disk mounted on a frame substrate 1, and N equally spaced clamp cylinders for clamping battery cells are arranged on the outer sides of the rotating disk. The multi-station rotating 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 rotating disk assembly 90 to the terminal battery cell collection point.

[0103] In the specific implementation process, when the pole piece is conveyed 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 pole piece is about to arrive, and the diaphragm is located below the pole piece.

[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, 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 to form a spiral cylindrical structure.

[0106] Subsequently, the winding and picking assembly 70 conveys the finished battery cells that have been glued to the next process, and conveys them to the multi-station rotating disk assembly 90 through the unloading assembly 80. The multi-station rotating 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 completed the perforation 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 maintenance point for battery cell repair and inspection through the battery cell conveying component 93.

[0108] See also Figure 8 As shown, the multi-station rotating disk assembly 90 includes a rotating disk 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 rotating disk 900. The multi-station rotating 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 evenly spaced in the circumferential direction of the rotary disc 900 , and the blanking clamps 902 are connected to the clamp cylinder 903 .

[0110] See also Fig. 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 slide cylinder 920 controls the movement of the detection frame 921 and the test clamp 922, 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, and if it passes the test, it will be transported to a unified collection point.

[0112] Embodiment 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 for automatically switching 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 Fig.10 and Fig.11 As shown, the complete equipment for winding button-type batteries with cut-off special-shaped pole pieces includes a frame substrate 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 arranged on the frame substrate 1.

[0116] The equipment box 2 is installed on the rack base plate 1 , and the interior of the equipment box 2 is a hollow structure, and a cooling fan is arranged in the equipment box 2 for heat dissipation inside the equipment box 2 .

[0117] See also Fig.11 As shown, the loading assembly 3 is arranged on the frame base plate 1. The loading assembly 3 includes a material box 30 for loading special-shaped pole pieces and a material box conveying module 31 for automatically switching the material box 30. 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 shaped electrode pieces so that the shaped electrode pieces can be evenly arranged in the material box 30 , and the material-taking robot assembly 200 automatically transports the shaped electrode pieces in the material box 30 .

[0119] Reference Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, that is, a schematic diagram of the structure for 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 a No. 1 bevel gear 312 is connected to the horizontally distributed conveyor belt 310, and a No. 2 bevel gear 313 is meshed on the No. 1 bevel gear 312, and a linkage belt 314 is connected between the back side of the No. 2 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 seat.

[0121] The material box 30 is disposed 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 cartridge 30 at its upper end through the conveyor belt 310. After the cartridge 30 moves to the position of the square groove on the equipment box 2, the controller 6 controls the cartridge 30 to pass through the square groove of the equipment box 2, so that the cartridge 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 cartridge 30 and conveys the special-shaped pole pieces. After the special-shaped pole pieces in the cartridge 30 complete the winding operation, the controller 6 controls the cartridge 30 to return to the equipment box 2 again. Then, the conveyor motor 315 in the equipment box 2 starts, and controls the other cartridges 30 loaded with special-shaped pole pieces on the conveyor belt 310 to reach the square groove of the equipment box 2, and makes them stretch out from the square groove, repeating the above feeding operation; and after the empty cartridge 30 moves to the designated feeding area, the operator places the special-shaped pole pieces into the cartridge 30.

[0124] Thus, 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 Fig.16 、 Fig.17 and Fig.18 As shown in, which is the structural schematic diagram of the cartridge 30 in the present application; specifically, the cartridge 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 of the two right-angle slides 300 in the length direction, there are symmetrically hinged sealing doors 301. The sealing doors 301 are telescopic structures. A U-shaped plate 302 is clamped and installed on the two right-angle slides 300. Horizontal chutes are provided in the horizontal direction on the U-shaped plate 302. Fixed columns 303 are arranged 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 plate 302. The limiting nuts 304 are threadedly connected to the fixed columns 303; A limiting rope 305 is slidably penetrated between the two fixed columns 303.

[0126] One end of the two fixed columns 303 away from each other is also screwed with a pressing screw sleeve 306.

[0127] It should be noted that the mutually screwed parts of the fixed column 303 and the pressing screw sleeve 306 are inclined structures that cooperate with each other. And one end of the fixed column 303 close to the pressing screw sleeve 306 will press and limit the limiting rope 305 under the extrusion of the pressing screw sleeve 306.

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

[0129] participate Fig.19 and Fig. 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, and rotate the tightening spiral sleeve 306 to move it away from the fixed column 303. At this time, the limiting rope 305 can move, and then according to the size of the pole piece, 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 to 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 pole pieces of different sizes, 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 the present 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 portion of the fixing column 303 provided with the spacing grooves tends to gather inward under the extrusion of the compression screw sleeve 306, and the portion 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 meet the storage requirements of different pole pieces, thereby maximizing the use of storage space and reducing the area occupied by the pole pieces. At the same time, it can also effectively improve the stability of the pole pieces in the material box 30, and further reduce the replacement of the material box 30, improve the use efficiency of the material box 30, and reduce cost consumption.

[0133] The present invention can also transport pole pieces of different shapes, thereby 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, the first linear translation module 2006 is drivingly connected to a swing arm module, the swing arm module includes a swing arm driving motor 2005 slidingly connected to the first linear translation module 2006 and a swing arm bracket assembly 2000 drivingly connected to the swing arm driving motor 2005, the swing arm bracket assembly 2000 includes a swing arm upper bracket 2001 connected to the output shaft of the swing arm driving motor 2005 and a swing arm lower bracket 2002 slidingly connected to the swing arm upper bracket 2001, the swing arm upper bracket 2001 is installed with a lifting cylinder 2003 for driving 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 a plurality of 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 absorb 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 absorbed electrode pieces are distributed in parallel with 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 absorbed to move in 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 separator 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 size of the pole piece required for the winding operation is small, the spacing between the vacuum nozzles 2004 can be adjusted to be smaller; conversely, if the size of the pole piece is large, the spacing between the vacuum nozzles 2004 can be adjusted to be larger.

[0139] During work: the first step is to prepare for 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 groove of the equipment box 2.

[0140] Step 2: When the material box 30 moves to the vicinity of the square groove 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 specified 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, 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.

[0142] Step 4: Two groups of material boxes 30 are arranged on the frame substrate 1, one group of material boxes 30 is specially used to load positive electrode sheets, and the other group of material boxes 30 is specially used to load negative electrode sheets. The positive electrode sheets and the negative electrode sheets are transported synchronously by 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 compression 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 compression 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 pole pieces of different sizes, 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 the present application.

[0145] Step 5: After the electrode is transported to the designated position, the electrode winding assembly 40 is started to start winding 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.

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

[0147] Step 7: The winding and picking assembly 70 then transports the finished battery cells that have been glued to the next process, and transports them to the multi-station rotating disk assembly 90 through the unloading assembly 80. The multi-station rotating disk assembly 90 then performs intermittent battery cell hot hole and short circuit tests on the finished battery cells to ensure that 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 completed the perforation 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 maintenance point for battery cell maintenance 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 protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
