Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, and in particular to a button battery electrode stacking device. Background Technology

[0002] Button batteries are a common type of battery. Their core consists of a positive electrode, a separator, and a negative electrode, primarily using either a wound or stacked structure. The positive and negative electrodes are alternately stacked, with the separator providing insulation between them. The positive electrode, separator, and negative electrode are then stacked together to form the battery core. Current methods involve manually stacking the electrodes on a workbench; this manual method is inefficient. Utility Model Content

[0003] The purpose of this invention is to provide a button cell electrode stacking device, which sets positive and negative electrode sheets on two follower mechanisms respectively, and then uses a rotating mechanism to clamp and rotate the electrode sheets, so that the positive and negative electrode sheets are stacked alternately to form the electrode core. It has the advantages of high production efficiency and good electrode sheet stacking quality.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a button battery electrode stacking device, including a worktable, an electrode pressing mechanism and two rotating mechanisms and a follower mechanism arranged around the electrode pressing mechanism. The follower mechanism is provided with an electrode guide groove that can rotate in coordination with the rotating mechanism. The electrode pressing mechanism is used to support and press the electrode extending from the electrode guide groove. The rotating mechanism clamps the electrode through a clamp and drives the electrode to rotate, so that the electrode layers are stacked in an interlaced manner to form an electrode core.

[0005] This invention employs the aforementioned technical solution. The positive and negative electrode sheets are respectively placed on the electrode guide grooves of two follow-up mechanisms. Two rotating mechanisms clamp the positive and negative electrode sheets using clamps and rotate alternately, causing the positive and negative electrode sheets to be stacked alternately. Each positive and negative electrode sheet is coated with an insulating diaphragm to maintain insulation between them. Simultaneously, the electrode guide grooves are adapted to cooperate with the rotation of the rotating mechanisms, ensuring that the guide grooves rotate by the same angle as the electrode sheets, preventing the electrode sheets from being twisted. This invention's processing device effectively improves work efficiency and ensures the processing quality of the electrode cores.

[0006] The aforementioned button cell electrode stacking device includes a rotating mechanism comprising a support plate and a first motor. The first motor is mounted on the support plate, and its first drive shaft is connected to a clamp via a first positioning plate. The first motor, connected to the clamp via the first positioning plate, drives the clamp to rotate, causing the clamp to rotate the electrode when clamping it.

[0007] In the aforementioned button battery electrode stacking device, a first bearing seat is provided on the support plate, and the drive shaft of the first motor passes through the first bearing seat to connect to the clamp. The first bearing seat serves to support the rotation of the motor's drive shaft, ensuring smooth movement when the first motor drives the clamp to rotate around the axis of the first motor's drive shaft.

[0008] The aforementioned button battery electrode stacking device includes a rotating mechanism that also includes a support base. The support base has a guide rail on its surface and a telescopic cylinder on its side. The piston rod of the telescopic cylinder is connected to a support plate via a connecting block, and the support plate slides on the guide rail via a slider. The telescopic cylinder drives the support plate to translate on the support base, thereby controlling the linear reciprocating motion of the first motor and the clamp. This allows the clamp to move towards the electrode guide groove to pick up the electrode, and then return to its original position, pulling the electrode to the electrode re-pressing mechanism position. This process demonstrates a high degree of automation.

[0009] The aforementioned button cell electrode stacking device includes a clamping cylinder and electrode grippers. The clamping cylinder drives the electrode grippers to open and close, thereby clamping and releasing the electrodes.

[0010] The aforementioned button cell electrode stacking device includes a follower mechanism comprising a fixed base, a second motor mounted on the fixed base, and a second bearing seat. The fixed base is located on a worktable. The second drive shaft of the second motor rotates through the second bearing seat and is connected to the electrode guide groove via a second positioning plate. The second motor, connected to the electrode guide groove via the second positioning plate, drives the electrode guide groove to rotate. When the fixture clamps the electrode and rotates, the second motor drives the electrode guide groove to rotate accordingly, achieving alternating stacking of the electrode sheets.

[0011] In the aforementioned button cell electrode stacking device, an electrode cover plate is detachably provided on the electrode guide groove. The electrode cover plate is used to keep the electrode in the electrode guide groove and prevent it from falling out when the electrode guide groove rotates.

[0012] The aforementioned button cell electrode stacking device includes a follower mechanism comprising a rotating guide plate mounted on a worktable. The rotating guide plate has a through hole, within which a thin-walled bearing is installed. An electrode guide groove passes through the inner ring of the bearing, and a rotating guide block is located outside the electrode guide groove, rotatable within the inner ring of the thin-walled bearing. The rotating guide plate supports the rotation of the electrode guide groove, ensuring smooth movement during rotation.

[0013] The aforementioned button cell electrode stacking device includes an electrode repressing mechanism comprising an upper repressing cylinder and a lower repressing cylinder. The upper repressing cylinder is connected to an upper repressing punch, and the lower repressing cylinder is connected to a lower repressing punch, with the upper and lower repressing punches positioned vertically opposite each other. The lower repressing cylinder drives the lower repressing punch upwards to support the electrode, while the upper repressing cylinder drives the upper repressing punch downwards to press the stacked electrode. As the electrode rotates, the upper and lower repressing cylinders respectively drive the upper and lower repressing punches away from the electrode, creating space for the electrode to rotate freely.

[0014] The aforementioned button cell electrode stacking device includes an electrode repressing mechanism comprising a support frame, an upper repressing cylinder, and a lower repressing cylinder mounted on the support frame.

[0015] The beneficial effects of this invention are as follows: The rotating mechanism uses a clamp to grip the electrode in the electrode guide groove and pull it to the position of the electrode re-pressing mechanism. A first motor drives the clamp to rotate the initially stacked positive and negative electrodes, allowing them to be alternately stacked. A second motor drives the electrode guide groove to rotate, cooperating with the clamp to rotate the electrodes and ensure their rotation, thus completing the alternating stacking. The electrode re-pressing mechanism is used to press the stacked electrodes together. This device can rapidly improve production efficiency and has a high degree of automation, meeting the continuity requirements of automated equipment operation. Attached Figure Description

The rotating mechanism 2 clamps the electrode through a clamp 20 and drives the electrode to rotate, so that the electrode is stacked in an interleaved manner to form an electrode core.

[0027] The rotating mechanism 2 includes a support plate 21 and a first motor 22. The first motor 22 is mounted on the support plate 21, and the first drive shaft 221 of the first motor 22 is connected to the clamp 20 through the first positioning plate 23.

[0028] The support plate 21 is provided with a first bearing seat 24, and the drive shaft of the first motor 22 passes through the first bearing seat 24 to connect to the clamp 20.

The piston rod of the telescopic cylinder 27 is connected to the support plate 21 through a connecting block 28. The support plate 21 slides on the guide rail 26 through a slider 29.

[0030] The clamp 20 includes a clamping cylinder 201 and an electrode gripper 202. The clamping cylinder 201 drives the opening and closing action of the electrode gripper 202.

[0031] The follower mechanism 3 includes a fixed base 32, a second motor 33 and a second bearing seat 34 mounted on the fixed base 32. The fixed base 32 is mounted on the worktable 1. The second drive shaft 331 of the second motor 33 rotates through the second bearing seat 34 and is connected to the electrode guide groove 31 through the second positioning plate 35.

[0032] An electrode cover plate 36 is detachably provided on the electrode guide groove 31.

[0033] The follower mechanism 3 includes a rotary guide plate 37 on the worktable 1. The rotary guide plate 37 has a through hole 30. A thin-walled bearing 38 is provided in the through hole 30. The electrode guide groove 31 passes through the inner ring of the bearing. A rotary guide block 39 is provided on the outside of the electrode guide groove 31 and can rotate within the inner ring of the thin-walled bearing 38.

[0034] The electrode repressing mechanism 4 includes an upper repressing cylinder 41 and a lower repressing cylinder 42.

The rotating mechanism 2 drives the support plate 21 to move forward via the telescopic cylinder 27, so that the clamp 20 approaches the corresponding electrode guide slot 31 and clamps the electrode.

Then, one of the rotating mechanisms clamps the two stacked electrodes in sequence and rotates them, and then the other rotating mechanism clamps the electrodes and rotates them, with a rotation angle of 180 degrees. During the alternating rotation, the electrode pressing mechanism 4 follows the action, alternately pressing each layer of stacked electrodes. At the same time, the follower mechanism 3 controls its electrode guide groove 31 to rotate synchronously with the corresponding clamp 20 to complete the rotational alternating stacking of electrodes.
