When in a material receiving station, one button cell slides into the material distributing mechanism 340 from the outlet at the lower end of the chute 230 under the action of self gravity, then the inlet is closed, and the driving component 320 drives the disc 330 to rotate in a unidirectional intermittent manner, so that the button cell is driven to move in a unidirectional intermittent manner at the top of the cylinder 310; the round disc 330 rotates, after the current notch staggers the outlet at the lower end of the chute 230, the outer edge of the round disc 330 can block the outlet at the lower end of the chute 230 to prevent button cells arranged in a row in the chute 230 from continuously sliding out, when the current notch rotates 90 DEG to enable the current notch to reach the disassembling station, the round disc 330 stops, the button cells in the separating mechanism 340 fall into the disassembling hole at the top of the cylinder 310 under the action of self gravity, the inlet of the separating mechanism 340 is opened again and reset, then the round disc 330 continuously rotates 90 DEG and stops to enable one round hole to be aligned with the disassembling hole (centered with the round hole), at this time, the disassembling ejection unit 400 acts, firstly disassembles the button cells in the disassembling hole, then ejects the button cells from the disassembling hole into the round hole, simultaneously rotates another notch to the receiving station, the next button cells continuously slide into the corresponding separating mechanism 340 from the outlet at the lower end of the chute 230, then the round disc 330 continuously rotates 90 DEG and stops, the button cells after the round hole is disassembled continuously moved along the top of the cylinder 310 to wait for the station, simultaneously moves the next button cells to the disassembling station and the disassembling hole and drops into the disassembling hole (centered with the round hole), the disassembling unit 400 is continuously rotated by the gravity after the disassembling of the round hole and the button cells continuously rotates the round hole and the next button cells continuously rotates down to enable the disassembling cell to be ejected from the disassembling station 400 to be aligned with the disassembling hole and the next button cell to be disassembled by the disassembling station and the next after the disassembling station is continuously and the disassembling station is continuously rotated, the initial notch reaches the receiving station and resets to meet the third button cell via its corresponding feed divider 340.

The button cell slides into the material distributing mechanism 340 from the outlet at the lower end of the chute 230 under the action of self gravity to enter the material receiving area, the sliding inertia of the button cell pushes the pair of L-shaped clamping strips 341 to leave the inclined planes at two sides of the notch and rotate around the hinging points respectively to be attached to the straight surfaces at the corresponding sides of the notch after overcoming the reset force of the spring, at the moment, the spring is compressed, the corners of the pair of L-shaped clamping strips 341 are mutually closed to close the inlet of the material distributing mechanism 340, and simultaneously, the subsequent button cell is prevented from sliding into the notch from the outlet at the lower end of the chute 230 to enter the material receiving area (the material distributing mechanism 340), so that the material distribution is realized, then, the button cell in the material receiving area falls into the disassembling hole at the top of the cylinder 310 under the action of self gravity along with the rotation of the disc 330 for 90 degrees, and the spring resets, the inlet of the material distributing mechanism 340 is opened to return to the initial state to receive the next button cell. That is, the relative rotation of the pair of L-shaped clamping strips 341 in the notch and the reset of the spring are utilized to adjust the size of the inlet of the distributing mechanism 340, so that the distribution of the button cell is realized, and the structure is simple and the practicability is high.

a disassembly mechanism mounted above the cylinder 310 for disassembling the button cells in the disassembly holes, and

The ejection mechanism 430 is installed inside the cylinder 310, and is used for supporting the button cell and ejecting the disassembled button cell from the disassembling hole into a circular hole of the disc 330.

After the button cell falls into the disassembly hole, the third motor 411 is started to rotate forward, the speed reducer 412 is used for reducing speed and increasing output torque, the transmission shaft 413 and the first cross rod 414 are driven to rotate synchronously, the first cross rod 414 rotates to drive (push) the second cross rod 421 to rotate, the screw rod of the scissor jack 422 rotates to enable the working end of the scissor jack 422 to move downwards (the downward moving distance is equivalent to the thickness of the disc 330 or the button cell, so that the second cross rod 421 and the first cross rod 414 still can keep a crossed push position relationship), the output torque is further amplified by the lever principle, and then the output torque passes through the round hole of the disc 330 downwards through the pressure head 423 to extend into the disassembly hole to extrude the button cell supported by the ejection mechanism 430, so that the inner cover and the outer cover of the button cell are mutually close (the components between the inner cover and the outer cover move along the radial direction) to prop up the outer cover, the disassembly is convenient for subsequent treatment, and then the third motor 411 rotates reversely to drive the pressure head 423 to exit the disassembly hole and move to the round hole above the disc 330 to the round hole of the next button cell. That is, by the speed reducer 412 of the power part 410 and the scissor jack 422 of the output part 420, a large moment can be output to utilize the pressure head 423 to squeeze the button cell for disassembly, thereby thoroughly solving the problem that the disassembly is not in place and the secondary disassembly is required and improving the disassembly efficiency.

After the button cell is extruded by the press head 423 to be disassembled, the fourth motor 432 is started while the press head 423 moves upwards, the driving cam 433 rotates, so that the pin shaft 434 slides in the chute to drive the ejector rod 435 to extend out of the sliding hole and move upwards, the disassembled button cell is ejected out of the disassembling hole into a round hole of the disc 330, and then the cam 433 continuously rotates, the ejector rod 435 moves downwards to the disassembling hole and retracts into the sliding hole, so that the next button cell arrives. Thus, the entire disassembly process is driven to be periodically performed by the combination of the geneva gear 323 and the cam 433. That is, the push rod 435 is controlled to reciprocate up and down by the cam 433, so that the disassembly and ejection of the button cell are realized, the button cell is two-purpose, the conception is ingenious, and the practicability is strong.
