Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a winding device for producing button batteries. Background Art

[0002] Button batteries usually consist of two layers of separators, an anode electrode and a cathode electrode. When winding, you need to first wind part of the two layers of separators on the winding needle, then roll the anode electrode and the cathode electrode into the separator, and then wind it again.

[0003] When the button battery production winding equipment in the prior art is in use, segmented cutting is often adopted. The length of the anode electrode sheet and the cathode electrode sheet is fixed, and manual loading is required.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3The present invention provides a technical solution: a winding device for button cell production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology, including a workbench 1, an air pump 100 is installed on the workbench 1, and also includes:

[0034] Cleaning mechanism 2: A cleaning mechanism 2 is provided on the workbench 1, and the cleaning mechanism 2 is used to clean the anode electrode piece and the cathode electrode piece.

[0035] As a further limitation of the cleaning mechanism 2 of the present invention, the cleaning mechanism 2 includes an air pipe A201, the air pipe A201 is fixedly connected to the workbench 1, the air pipe A201 is connected to the air pump 100 through a hose, and two groups of air pipes B202 are arranged on one side of the air pipe A201, each group has two, and the two groups of air pipes B202 are connected to a cleaning pipe A203 at one end away from the air pipe A201, and a Y-shaped groove 204 is opened through the cleaning pipe A203.

[0036] The cleaning mechanism 2 also includes a connecting pipe 205, one end of the cleaning pipe A203 is connected to the connecting pipe 205, one end of the connecting pipe 205 is symmetrically fixedly connected to an M-shaped frame 206, the other end of the air pipe A201 is connected to the M-shaped frame 206, the other ends of the two groups of air pipes B202 are both connected to the M-shaped frame 206, a brush roller 207 is symmetrically rotatably connected in the M-shaped frame 206, a through hole is opened in the middle of the rotating shaft of the brush roller 207, an impeller 208 is fixedly connected in the through hole, when the air in the air pipe A201 passes through the M-shaped frame 206, it can blow the impeller 208 to drive the brush roller 207 to rotate, and a connecting box 209 is fixedly connected to one side of the M-shaped frame 206.

[0037] When the battery cell needs to be wound, the staff will first put one end of the anode electrode piece and the cathode electrode piece into the two cleaning tubes A203 respectively, and move the anode electrode piece and the cathode electrode piece to the side close to the connecting tube 205, and start the air pump 100 at the same time. The air pump 100 conveys air into the air supply pipe A201, and enters the Y-shaped groove 204 of the cleaning tube A203 through the air supply pipe A201, the M-shaped frame 206 and the air supply pipe B202, and then blows the middle part of the anode electrode piece and the cathode electrode piece. It is worth noting that the air flow rate generated by the air pump 100 is weak, and the air will not cause the anode electrode piece and the cathode electrode piece to be smeared when blowing on the anode electrode piece and the cathode electrode piece. The pole pieces float, and the dust or other impurities in the middle of the anode pole piece and the cathode pole piece are blown away and discharged through the fork of the Y-shaped groove 204, and then the anode pole piece and the cathode pole piece enter between the two M-shaped frames 206 through the connecting tube 205. At this time, the air blows the impeller 208, so that the impeller 208 drives the brush roller 207 to rotate slowly, and the brush roller 207 cleans both sides of the surface of the anode pole piece and the cathode pole piece, and then the anode pole piece and the cathode pole piece enter the connecting box 209 through the two M-shaped frames 206. The above steps can completely clean the dust or other impurities on the surface of the anode pole piece and the cathode pole piece, thereby preventing problems after winding.

[0038] Example 2: Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The present invention provides a technical solution: a winding device for button battery production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A straightening mechanism 3 is provided on the workbench 1. The straightening mechanism 3 is used to keep sufficient tension between the anode electrode sheet and the cathode electrode sheet, thereby preventing wrinkles from being generated when the anode electrode sheet and the cathode electrode sheet are wound.

[0039] As a further limitation of the straightening mechanism 3 of the present invention, the straightening mechanism 3 includes a rectangular frame 301, two rectangular frames 301 are embedded and fixed on the workbench 1, a slide groove A is opened in the two rectangular frames 301, a sliding frame 302 is slidably connected in the slide groove A, a first elastic member is arranged between the sliding frame 302 and the slide groove A, the first elastic member is a compression spring, a slider 303 is symmetrically slidably connected in the sliding frame 302, a second elastic member is arranged between the slider 303 and the sliding frame 302, the second elastic member is a compression spring, and a damping roller 304 is rotatably connected to one side of the slider 303.

[0040] The straightening mechanism 3 also includes a rocker rod 305. The two rectangular frames 301 are both provided with special-shaped grooves symmetrically about the slide groove A. The other side of the slider 303 is fixedly connected to a sliding shaft used in conjunction with the special-shaped groove. The two rectangular frames 301 are both hinged with rocker rods 305 used in conjunction with the sliding shaft. A third elastic member is arranged between the rocker rod 305 and the rectangular frames 301. The third elastic member is a torsion spring. An elastic wedge block 306 used in conjunction with the sliding shaft is slidably connected in the special-shaped groove.

[0041] Initially, the two adjacent sliders 303 are in a state of being close to each other, and the anode pole piece and the cathode pole piece enter between the two adjacent damping rollers 304 after passing through the connection box 209. When the anode pole piece and the cathode pole piece move, friction force is applied to the two adjacent damping rollers 304. The two damping rollers 304 rotate with the anode pole piece and the cathode pole piece under the action of friction force. At the same time, the two damping rollers 304 generate friction force on the corresponding slider 303. It is worth noting that the friction force generated by the damping roller 304 increases with the increase of its rotation speed. At this time, because the anode pole piece and the cathode pole piece are manually pushed and moved, and the moving speed is slow, thereby making the rotation speed of the damping roller 304 slow, the friction force applied by the damping roller 304 to the slider 303 is smaller than that of the first elastic member. The elastic force of the slider 303 cannot push the adjacent sliding frame 302 to slide. When the anode electrode piece and the cathode electrode piece move to contact the diaphragm, the diaphragm, the anode electrode piece and the cathode electrode piece begin to be wound. At this time, the movement speed of the anode electrode piece and the cathode electrode piece increases, and the rotation speed of the damping roller 304 reaches the limit. The movement of the anode electrode piece and the cathode electrode piece exerts a force on the damping roller 304 to move close to the adjacent rocker 305, thereby making the friction force exerted by the damping roller 304 on the slider 303 exceed the elastic force of the first elastic member. At this time, the two adjacent damping rollers 304 drive the corresponding slider 303 to slide, and the slider 303 drives the corresponding sliding frame 302 to slide along the slide groove A of the corresponding rectangular frame 301. The first elastic member between the sliding frame 302 and the slide groove A is contracted by force. It is worth noting It is worth noting that in the prior art, when winding the anode and cathode pole pieces, the staff needs to press their fingers on the surface of the anode and cathode pole pieces, so as to continuously apply tension to the anode and cathode pole pieces. When the finger position moves, it is very easy to cause the anode and cathode pole pieces to lose tension or shift. Through the above steps, the damping roller 304 can follow the movement of the anode and cathode pole pieces, so that the anode and cathode pole pieces are continuously subjected to tension, thereby preventing the anode and cathode pole pieces from losing tension prematurely and generating wrinkles during the winding process. At the same time, the slider 303 drives the corresponding sliding shaft to slide along the special-shaped groove. When the anode and cathode pole pieces are about to complete winding, the sliding shaft slides to the corner of the special-shaped groove, thereby causing the two adjacent sliders 303 to slide away from each other. , the second elastic member between the slider 303 and the sliding frame 302 is contracted by force, and the two adjacent damping rollers 304 move away from each other. After the damping roller 304 moves, it no longer contacts the anode pole piece and the cathode pole piece, and loses friction and stops rotating. The anode pole piece and the cathode pole piece quickly complete winding. At the same time, due to the fast movement speed of the anode pole piece and the cathode pole piece when winding, inertia is generated when the sliding shaft slides. The sliding shaft slides under the influence of inertia until it contacts the adjacent swing rod 305 and the elastic wedge block 306. The swing rod 305 is forced to rotate with its hinge with the rectangular frame 301 as the center of the circle, and the third elastic member is forced to contract, and the elastic wedge block 306 is forced to contract and slide. Then the sliding shaft passes over the adjacent swing rod 305 and the elastic wedge block 306 and no longer contacts the two.The third elastic member is released to drive the swing rod 305 to rotate and reset, and the elastic wedge block 306 is released to slide and reset. Since the damping roller 304 loses friction at this time, the damping roller 304 no longer applies friction to the corresponding slider 303, thereby enabling the sliding frame 302 to move. At this time, the first elastic member is released to drive the sliding frame 302 to slide and reset, and the sliding frame 302 drives the corresponding two sliders 303 to slide. At this time, the sliding shaft contacts the surface of the elastic wedge block 306, and the second elastic member remains in a contracted state, thereby preventing the slider 303 from resetting too quickly and driving the damping roller 304 to contact the anode and cathode electrodes. The surfaces of the pole pieces are in contact, resulting in damage to the surfaces of the anode pole piece and the cathode pole piece. Then the slide shaft slides to the swing rod 305. Since the swing rod 305 cannot rotate at this time, the second elastic member continues to remain in a contracted state, and the slide shaft continues to slide along the special-shaped groove. When the slide shaft slides to the right angle of the special-shaped groove, the slide frame 302 no longer slides, the first elastic member is completely released, and the second elastic member is released to allow the slider 303 to drive the damping roller 304 to reset, thereby achieving the application of tension to the anode pole piece and the cathode pole piece through the straightening mechanism 3 to prevent the anode pole piece and the cathode pole piece from losing tension too early and generating wrinkles.

[0042] Example 3: Please refer to Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 The present invention provides a technical solution: a winding device for button battery production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A winding mechanism 4 is provided on the workbench 1. The winding mechanism 4 is used to wind the anode electrode sheet, the cathode electrode sheet and the diaphragm.

[0043] As a further limitation of the winding mechanism 4, the winding mechanism 4 includes a stepper motor 401, a stepper motor 401 is installed on the rear side of the workbench 1, a circular guide rail 402 is fixedly connected to the workbench 1, the output shaft of the stepper motor 401 rotates and passes through the circular guide rail 402 and is fixedly connected to a connecting frame 403, and two winding needles 404 are rotatably connected to the connecting frame 403, one end of the two winding needles 404 are both inserted into the circular guide rail 402 and slide in the circular guide rail 402, a driving assembly 405 is installed on the connecting frame 403, the driving assembly 405 consists of a driving motor, a first pulley, two second pulleys and a belt, wherein the driving motor is installed on the connecting frame 403, the first pulley is fixed to the output shaft of the driving motor, the two second pulleys are symmetrically rotatably connected to the connecting frame 403, the belt transmission is connected to the first pulley and the two second pulleys, and the two second pulleys are respectively fixedly sleeved on the outer walls of the two winding needles 404.

[0044] The winding mechanism 4 also includes a guide block 406, a guide block 406 is fixedly connected in the annular guide rail 402, a slide groove B is opened in the winding needle 404, a piston block 407 is slidably connected in the slide groove B, a fourth elastic member is arranged between the piston block 407 and the slide groove B, the fourth elastic member is a reset spring, the outer wall of the winding needle 404 is slidably connected with a sliding block 408 used in conjunction with the guide block 406, and is slidably connected with a material return plate 409, a slide groove C is opened on the winding needle 404 and is connected to the slide groove B, an L-shaped rod is fixedly connected to the piston block 407, the L-shaped rod is stuck in the slide groove C and slides in the slide groove C, one end of the L-shaped rod is fixedly connected to the material return plate 409, a cross bar is symmetrically fixedly connected to one side of the sliding block 408, one end of the cross bar slides through the winding needle 404 and is fixedly connected to the piston block 407.

[0045] The winding mechanism 4 also includes an electric push rod 410, which is installed on the workbench 1. The rear side of the workbench 1 is slidably connected to two racks 411, and the rear side of the workbench 1 is rotatably connected to a gear 412 that meshes with the two racks 411. One end of the two racks 411 is fixedly connected to a cutting rack 413. Two slide grooves D are provided on the workbench 1. The cutting rack 413 is inserted into the slide grooves D and slides in the slide grooves D. The telescopic end of the electric push rod 410 is fixedly connected to one of the cutting racks 413.

[0046] The winding mechanism 4 also includes a cutting knife 414, in which the cutting knife 414 is slidably connected in a cutting frame 413, a fifth elastic member is arranged between the cutting knife 414 and the cutting frame 413, the fifth elastic member is a force storage spring, a vertical shaft 415 is fixedly connected to the top of the cutting knife 414, the top end of the vertical shaft 415 slides through the cutting frame 413 and is rotatably connected to a one-way damping wheel 416 through a mounting plate, and a contact strip 417 used in conjunction with the one-way damping wheel 416 is fixedly connected to one side of the workbench 1.

[0047] The winding mechanism 4 also includes a receiving seat 418, which is slidably connected to another cutting frame 413. A sixth elastic member is arranged between the receiving seat 418 and the other cutting frame 413. The sixth elastic member is a return spring. A knife groove for use with the cutting knife 414 is opened on the receiving seat 418.

[0048] Initially, the fifth elastic member is in a contracted state, and the cutting knife 414 is completely stored in the cutting frame 413 on the upper side. When the diaphragm, the anode electrode piece and the cathode electrode piece need to be wound, the driving motor in the driving assembly 405 is started, and the output shaft of the driving motor drives the first pulley to rotate at a high speed, and the first pulley drives the two second pulleys to rotate at a high speed through the belt, and the two second pulleys drive the corresponding winding needles 404 to rotate at a high speed. At this time, the winding needle 404 close to the side of the rectangular frame 301 begins to wind the diaphragm, the anode electrode piece and the cathode electrode piece. After the winding is completed, the electric push rod 410 is started, and the telescopic end of the electric push rod 410 drives one of the racks 411 to descend downward, and then drives the other rack 411 to lift upward through the gear 412, so that the two cutting pieces are wound. The racks 413 move close to each other. At this time, the cutting rack 413 on the upper side drives the cutting knife 414 to descend quickly. The cutting knife 414 drives the one-way damping wheel 416 to descend quickly through the vertical shaft 415 and the mounting plate. At this time, the one-way damping wheel 416 rotates with the contact strip 417 due to friction. Due to the characteristics of the one-way damping wheel 416, the rotation speed of the one-way damping wheel 416 is slow, so that the descending speed of the one-way damping wheel 416 is slower than the descending speed of the cutting rack 413. As the cutting rack 413 descends, the one-way damping wheel 416 can apply an upward pulling force to the cutting knife 414 through the mounting plate and the vertical shaft 415. The cutting knife 414 is forced to slow down its descending speed. At this time, the fifth elastic member between the cutting knife 414 and the cutting rack 413 is forced to contract and store force. After the one-way damping wheel 416 continues to descend, it no longer contacts the contact strip 417, thereby enabling the cutting knife 414 to move. At the same time, the ends of the two cutting frames 413 that are close to each other abut against each other, and the receiving seat 418 contacts and is squeezed with the bottom end of the upper cutting frame 413. The receiving seat 418 slides and descends, causing the sixth elastic member to contract. The fifth elastic member is released to drive the cutting knife 414 to quickly descend and slide. When the fifth elastic member is completely released, due to the inertia of the cutting knife 414 and the elasticity accumulated by the fifth elastic member, the cutting knife 414 continues to descend. Subsequently, the blade of the cutting knife 414 contacts the diaphragm and hits the knife groove of the receiving seat 418 to cut the diaphragm. At this time, the receiving seat 418 slides and descends under the impact, thereby causing the sixth elastic member to contract again, thereby 414 is used for buffering to prevent the rigid impact force of the cutting knife 414 from being too large, which may cause damage to the cutting knife 414 and the receiving seat 418. Then the fifth elastic member contracts to drive the cutting knife 414 to lift, thereby completing the cutting of the diaphragm. Then the telescopic end of the electric push rod 410 drives one of the racks 411 to lift and reset, thereby causing the two cutting frames 413 to slide and reset. The upper cutting frame 413 drives the cutting knife 414 to lift, and then the one-way damping wheel 416 rotates by friction with the contact strip 417. Due to the characteristics of the one-way damping wheel 416, the one-way damping wheel 416 will not be affected and rotates normally. At the same time, the receiving seat 418 no longer contacts the bottom end of the upper cutting frame 413, so that the sixth elastic member is released to drive the receiving seat 418 to slide and reset.

[0049] Then start the stepper motor 401, the output shaft of the stepper motor 401 drives the two winding needles 404 and the driving assembly 405 to rotate 180 degrees clockwise through the connecting frame 403, and the two winding needles 404 drive the sliding block 408 thereon to slide along the annular guide rail 402. At this time, the sliding block 408 on the right side contacts the guide block 406 after sliding and slides along the surface of the guide block 406. The sliding block 408 drives the corresponding piston block 407 to slide through the cross bar thereon. At this time, the fourth elastic member is forced to shrink, and the piston block 407 drives the corresponding unloading plate 409 to slide through the L-shaped rod. If the winding needle 404 corresponding to the unloading plate 409 is wound with a diaphragm, The anode electrode sheet and the cathode electrode sheet, after the material unloading plate 409 slides, the diaphragm, the anode electrode sheet and the cathode electrode sheet can be pushed down the winding needle 404, thereby completing the automatic material unloading, and then the sliding block 408 passes over the guide block 406 and no longer contacts the guide block 406. At this time, the piston block 407 can move, and the fourth elastic member is released to drive the piston block 407 to slide and reset. The piston block 407 drives the corresponding sliding block 408 to reset through the two cross bars thereon, and drives the material unloading plate 409 to slide and reset through the L-shaped rod thereon. The above steps can effectively improve the winding efficiency, and then repeat the above steps to wind the diaphragm, the anode electrode sheet and the cathode electrode sheet, thereby completing the winding work of the entire equipment.
