Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to an integrated device for cell punching and short circuit detection and a cylindrical button-type cell sheet making and winding machine having the integrated device. Background Art

[0002] In the production process of cylindrical button batteries, the rolled battery cells often need to undergo hot-hole punching and short-circuit testing before the next production process can be carried out. The existing battery cell hot-hole punching and short-circuit testing processes are arranged on a conveyor belt, which transports multiple cylindrical battery cells to the hot-hole punching device and short-circuit detection device, where they are taken out and processed or tested accordingly.

[0003] The problem with the existing method of cell punching and short-circuit testing is that due to the long conveyor belt, vibration is inevitably generated during operation, causing the cell to shift in position, resulting in positioning deviation, and further causing problems such as inaccurate punching and poor contact in short-circuit testing. Summary of the invention

[0004] The first object of the present invention is to provide an integrated device for cell punching and short circuit detection with improved processing accuracy.

[0005] The second object of the present invention is to provide a cylindrical button-type battery cell film-making and winding machine with improved processing accuracy.

[0006] The first object of the present invention provides an integrated device for punching holes and detecting short circuits in a battery cell, comprising a machine base, a punching hole device and a short circuit detection device, wherein a punching hole station is formed on the punching hole device, and a detection station is formed on the short circuit detection device; the machine base comprises a fixed portion, a sliding portion arranged on the fixed portion and a first linear drive unit, wherein the first linear drive unit drives the sliding portion to move along the y-axis direction relative to the fixed portion; the integrated device for punching holes and detecting short circuits in a battery cell further comprises a clamping device to be taken, wherein a clamping position to be taken is formed on the clamping device to be taken, the punching hole device, the short circuit detection device and the clamping device to be taken The clamping devices are sequentially arranged on the sliding part along the y-axis direction; the integrated equipment for cell perforation and short-circuit detection also includes a grasping device arranged on the fixed part, the grasping device includes two first grasping mechanisms arranged along the y-axis direction, one first grasping mechanism is movable between the perforation station and the detection station, and the other first grasping mechanism is movable between the detection station and the clamping position to be taken. In the y-axis direction, the perforation station, the detection station and the clamping position to be taken are equidistantly arranged at a first distance, and the distance between the two first grasping mechanisms is the first distance.

[0007] It can be seen from the above scheme that since the spacing between the two first grasping mechanisms on the grasping device is equal to the spacing between any two adjacent ones of the punching station, the detection station and the clamping station to be taken, the integrated equipment can simultaneously perform different processing procedures for two battery cells; the battery cell is sent to the punching station by the unloading robot, the heated punching needle passes through the battery cell and keeps the battery cell fixed, and then the sliding part moves forward a first distance, at which time the punching station is located directly below the first first grasping mechanism, the first first grasping mechanism falls and grasps the battery cell that has completed the punching process, the punching needle retreats, the first first grasping mechanism rises and the slide The moving part retreats to the initial position; the unloading robot continues to send the second battery cell to the hot punching station, while the first grabbing mechanism moves down and sends the first battery cell to the detection station for short circuit detection; then the first grabbing mechanism rises, and the sliding part advances the first distance again. At this time, the two first grabbing mechanisms are respectively located directly above the hot punching station and the detection station, and they can be lowered to grab the two battery cells at the same time. Then the sliding part retreats the first distance, the first battery cell will be transferred to the waiting clamping position to wait for reception, and the second battery cell will be transferred to the detection station. At this time, the third battery cell will be sent to the hot punching station by the unloading robot, and the cycle continues. The battery cell hot punching and short circuit detection integrated equipment provided by the present invention uses a robot to realize the progressive transfer of the battery cell between multiple stations or clamping positions, realizes the processing of two battery cells in different processes at the same time, and ensures the positioning accuracy, thereby improving the processing accuracy.

[0009] As can be seen from the above, the two first gripping mechanisms cooperate with the second gripping mechanism to realize the progressive transportation of the battery cells, thereby ensuring the positioning accuracy of each battery cell when it is sent out by the transfer device, thereby ensuring the positioning accuracy of the next step.

[0011] As can be seen from the above, this arrangement increases the flexibility of the second gripping mechanism while ensuring the accuracy of positioning the battery cell, thereby making the spatial arrangement between multiple integrated devices in the cylindrical button-type battery cell film-making and winding machine more compact.

[0012] A further solution is that the second grabbing mechanism includes two second grabbing arms movable along the y-axis direction, and a second grabbing position is formed between the two second grabbing arms in the y-axis direction.

[0013] A further solution is that the first grasping mechanism includes two first grasping arms movable along the y-axis direction, and a first grasping position is formed between the two first grasping arms in the y-axis direction.

[0014] A further solution is that the clamping device to be taken includes two clamping arms to be taken that can move along the z-axis direction, and in the z-axis direction, a clamping position to be taken is formed between the two clamping arms to be taken.

[0015] As can be seen from the above, the first grabbing arm and the second grabbing arm are both coordinated with the clamping arm to be taken at the clamping position to be taken. The two first grabbing arms are arranged along the y-axis direction, the two second grabbing arms are arranged along the y-axis direction, and the two clamping arms to be taken are arranged along the z-axis direction. This setting allows the grabbing arm and the clamping arm to transfer the battery cells without interference, thereby ensuring the smoothness of the battery cell transportation.

[0016] A further solution is that the first grabbing arm has a first abutting surface facing the first grabbing position, the to-be-taken clamping arm has a to-be-taken abutting surface facing the to-be-taken clamping position, and the first abutting surface and / or the to-be-taken abutting surface are concave bending surfaces or concave arc surfaces.

[0017] As can be seen from the above, the first abutting surface and the abutting surface to be removed are configured as concave bending surfaces or concave arc surfaces so as to position and clamp the battery cell without damaging the battery cell.

[0018] A further solution is that the ironing device includes a fourth linear drive unit, a heating unit, an ironing needle and an ironing needle socket, and the fourth linear drive unit, the heating unit and the ironing needle socket are arranged on the sliding part in sequence along the x-axis direction, and a ironing station is formed between the heating unit and the ironing needle socket; the ironing needle is connected to the fourth linear drive unit, the ironing needle passes through the heating unit, and the fourth linear drive unit drives the ironing needle to move along the x-axis direction.
