DETAILED DESCRIPTION

[0024] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A battery shell segmented sheeting mechanism includes a blanking die 2, a driving source unit and a conveyor belt 3. The blanking die 2 is installed on the discharge side of a punch press. Pads 202 are provided on both sides of the bottom of the blanking die 2.

The blanking channel 201 on the second side of the blanking die 2 is located between two adjacent blanking channels 201 on the first side of the blanking die 2.

[0028] A clamping unit is arranged in the blanking channel 201, and the clamping unit includes two clamping pieces 4 arranged opposite to each other. The inner wall of the blanking channel 201 is provided with a displacement groove 7 for the clamping pieces 4 to be slidably connected, so that the two clamping pieces 4 can be telescopically and movably arranged on the inner wall of the blanking channel 201.

[0029] The driving source unit includes two telescopic cylinders 13 arranged opposite to each other, and the opposite ends of the piston rods of the two telescopic cylinders 13 are provided with travel plates 14, and the travel plates 14 extend along the length direction of the blanking die 2. The blanking die 2 is provided with a travel groove 15 for the travel plate 14 to perform telescopic activities. A clamping piece 4 of the clamping unit is fixedly connected to the stroke plate 14 it is close to, and another clamping piece 4 of the clamping unit is connected to the stroke plate 14 it is close to through a slide plate 8. A slide groove 9 for sliding connection of the slide plate 8 is provided in the blanking die 2, and the slide groove 9 is connected to its corresponding displacement groove 7. Preferably, the slide plate 8 is provided with a limiting portion 11, and the inner wall of the slide groove 9 is provided with a limiting groove 12 for sliding connection of the limiting portion 11, so as to guide and limit the sliding activity of the slide plate 8.

[0030] The clamping piece 4 is provided with a lifting groove 23 extending along the axial direction of the blanking channel 201, and the lifting groove 23 is slidably connected with a lifting part 24. The side wall of the lifting part 24 cooperates with the side wall of the clamping piece 4, and the lifting part 24 is provided with a guide column 25. The lifting groove 23 is provided with a guide hole 26 for the guide column 25 to be inserted, and a buffer member 27 is provided between the lifting part 24 and the lifting groove 23. The buffer member 27 can be a spring structure, and the spring structure is sleeved on the guide column 25.

[0031] The piston rods of the two telescopic cylinders 13 of the driving source unit can extend relative to each other synchronously, so that the clamping pieces 4 on the two stroke plates 14 are close to each other in the blanking channel 201, until the stroke plate 14 conflicts with the first side of the stroke groove 15, and the opposite sides of the two clamping pieces 4 of the clamping unit cooperate with the inner wall of the blanking channel 201, and the part of the lifting part 24 extending out of the displacement groove 7 is provided with a supporting part 10, and the supporting part 10 is an arc-shaped inner concave cavity structure, and the supporting part 10 is adapted to the periphery of the elliptical or circular sheet 1, and the top surface of the supporting part 10 is horizontally arranged for The two supporting parts 10 in the supporting sheet 1 and the blanking channel 201 cooperate to form a clamping position 5 that restricts each sheet 1 to be stacked in the blanking channel 201; or the piston rods of the two telescopic cylinders 13 of the driving source unit can move back and forth synchronously, so that the clamping parts 4 on the two stroke plates 14 are away from each other in the blanking channel 201 until the stroke plate 14 conflicts with the second side of the stroke groove 15, and the supporting part 10 retreats to the displacement groove 7. At this time, the opposite sides of the supporting parts 10 of the two clamping parts 4 of the clamping unit form a through space 6 for the sheet 1 to pass through.

[0032] Preferably, five driving source units may be provided, and each driving source unit corresponds to each material clamping unit.

[0033] Two clamping units are arranged in the blanking channel 201, and the two clamping units are arranged at intervals along the axial direction of the blanking channel 201. When the punch press performs continuous blanking operations, the sheet 1 dropped from the blanking opening falls into the blanking channel 201, and the sheet 1 passes through the penetration space 6 formed by the two clamping members 4 of the clamping unit located at the upper part of the blanking channel 201 and falls onto the clamping position 5 formed by the two clamping members 4 of the clamping unit located at the lower part of the blanking channel 201 extending out.

[0034] When the sheets 1 on the clamping position 5 at the lower part of the blanking channel 201 are stacked to a predetermined number, the stacked sheets 1 are returned through the through-space 6 formed by the two clamping members 4 of the clamping unit at the lower part of the blanking channel 201, so that the stacked sheets 1 are output to the outside of the blanking die 2 along the blanking channel 201. The clamping unit at the lower part of the blanking channel 201 reduces the blanking height of the stacked sheets 1, so that the stacked sheets 1 fall more stably onto the working surface of the conveyor belt 3, and the setting of the pad 202 makes the discharge port of the blanking channel 201 There is a height difference between the discharge port of the blanking channel 201 and the working surface of the conveyor belt 3. The space between the discharge port of the blanking channel 201 and the working surface of the conveyor belt 3 is for the stacked sheets 1 to pass through, so that the conveyor belt 3 can smoothly transport the stacked sheets 1. In this process, the two clamping positions 5 of the clamping unit located at the upper part of the blanking channel 201 extend to form a clamping position 5 that prevents the sheets 1 from falling into the lower part of the blanking channel 201, ensuring that the number of stacked sheets 1 output by the blanking channel 201 meets the predetermined number, and the sheets 1 stacked to the predetermined number are discharged through the conveyor belt 3.

[0035] After the blanking channel 201 completes outputting the sheets 1 stacked to a predetermined number, the two clamping parts 4 of the clamping unit located at the lower part of the blanking channel 201 extend out to form a clamping position 5, and the two clamping parts 4 of the clamping unit located at the upper part of the blanking channel 201 retreat to form a through space 6, so that the next group of sheets 1 stacked to a predetermined number collected by the clamping unit located at the upper part of the blanking channel 201 fall onto the clamping position 5 formed by the clamping unit located at the lower part of the blanking channel 201, completing the cycle.

[0036] The sheet dropping mechanism guides the punched sheets 1 to be smoothly stacked on the clamping position 5 through the dropping channel 201, avoiding scratches and scrapes on the sheets 1 due to collision with each other, and realizing segmented stacking of the stacked sheets 1, saving time and effort and improving collection efficiency.

The rotating motor 16 drives the driving wheel 18 to rotate so that it drives the two clamping parts 4 of the clamping unit to approach or move away synchronously through the synchronous belt 20.
