[0045] A battery cell return frame lifting mechanism 2, which is used for lifting the battery cell return frame 6 stacked on the battery cell return frame stacking mechanism 1 to a predetermined picking height;

[0046] A release paper removing mechanism 4, which is used for clamping the tearing edge 501 of the release paper 5 on the battery cell return frame 6;

[0048] The battery cell return frame stacking mechanism 1, the battery cell return frame lifting mechanism 2, the release paper removing mechanism 4 and the manipulator picking, tearing and attaching mechanism 3 are all arranged on the surface of the workbench cabinet 9. An electric control, pneumatic control and other system devices for driving the above - mentioned mechanisms to work are arranged in the workbench cabinet 9.

[0049] As Figure 2 and Figure 3 shown, in this embodiment, the battery cell return frame stacking mechanism 1 includes a turntable 101, a plurality of battery cell return frame carrier mounting positions 102 are arranged on the turntable 101, and battery cell return frame carrier assemblies 103 are arranged on the battery cell return frame carrier mounting positions 102, and the battery cell return frame carrier assemblies 103 are used for longitudinally stacking the battery cell return frames 6;

[0050] Each of the installation positions 102 of the battery cell loop frame carriers is provided with a jacking through slot 104 through which the battery cell loop frame jacking mechanism 2 can pass; the battery cell loop frame jacking mechanism 2 drives the battery cell loop frame 6 to move up and down through the jacking through slot 104;

[0051] The turntable 101 is driven by a motor rotation module 113 arranged on the workbench cabinet 9 to rotate clockwise or counterclockwise.

[0052] As a specific embodiment of the present solution, there are four installation positions 102 of the battery cell loop frame carriers, which are symmetrically arranged on the surface of the turntable 101.

[0053] Correspondingly, there are four battery cell loop frame carrier assemblies 103. In this structure, by rotating the turntable 101, it is possible to drive the four battery cell loop frame carrier assemblies 103 to rotate, and thus it is possible to synchronously perform the material coding and feeding of the battery cell loop frames 6, ensuring the continuous progress of the work.

[0054] As a specific embodiment of this solution, the device can simultaneously feed 2 battery cell loop frames 6, that is, 2 of the four battery cell loop frame carrier assemblies 103 are taken as a group, and the pick-and-place mechanism 3 for the manipulator to pick up materials and tear and attach paper picks up the battery cell loop frames 6 in 2 battery cell loop frame carrier assemblies 103 at a time.

[0055] The battery cell loop frame carrier assembly 103 includes a loop frame carrier base 107, and a carrier base slot 108 corresponding to the jacking through slot 104 is provided on the loop frame carrier base 107;

[0056] A loop frame carrier 109 is arranged in the carrier base slot 108, and the loop frame carrier 109 is movably sleeved with carrier guiding columns 110 symmetrically arranged on both sides of the carrier base slot 108, and the battery cell loop frames 6 are stacked on the loop frame carrier 109;

[0058] In addition, a locking hole 105 is provided on the installation position 102 of the battery cell loop frame carrier, and a lock catch 106 capable of locking the locking hole 105 is arranged on the loop frame carrier base 107. Through this structure, the battery cell loop frame carrier assembly 103 can be quickly assembled or disassembled with the turntable 101.

[0059] Such as Figure 2 and Figure 3As shown, in this embodiment, the core loop frame lifting mechanism 2 includes a pair of lifting brackets 201 disposed on the surface of the workbench cabinet 9. An inner side of the lifting bracket 201 is provided with a lifting drive module 202. A lifting plate 203 is connected to a slider of the lifting drive module 202, and a lifting plate through slot 204 for the lifting plate to pass through is formed on the surface of the workbench cabinet 9.

[0060] In this embodiment, the lifting drive module 202 can be a motor screw drive module or a linear slide table module vertically installed on the lifting bracket 201.

[0061] Driven by the motor rotation module 113, the turntable 101 makes a rotational movement, driving the 2 core loop frame carriers 103 after loading to the working area of the lifting drive module. At this time, the 2 lifting through slots 104 respectively correspond to the 2 lifting plate through slots 204.

[0062] Under the action of the lifting drive module 202, the lifting plate 203 makes a synchronous upward movement and acts on the bottoms of the 2 loop frame carriers 109, gradually lifting them, thereby realizing lifting the core loop frame 6 at the topmost position to a predetermined picking height for the manipulator picking and paper tearing and attaching mechanism 3 to pick up the material.

[0063] As Figure 4 shown, in this embodiment, the manipulator picking and paper tearing and attaching mechanism 3 includes a robot fixing seat 301 fixedly connected to the surface of the workbench cabinet 9. A four-axis robot 302 is provided on the robot fixing seat 301. A vacuum chuck assembly 304 capable of sucking the core loop frame 6 is connected to a terminal rotating shaft 303 of the four-axis robot 302. Through the vacuum chuck assembly 304, the core loop frame 6 on the loop frame carrier 109 can be stably and accurately sucked, and through axial movement, the position transfer of the sucked core loop frame 6 is realized, enabling it to be accurately transferred to the adjacent release paper removing mechanism 4 for removing the release paper 5.

[0064] Specifically, the vacuum chuck assembly 304 includes a connecting plate 306 connected to the terminal rotating shaft of the four-axis robot 302 through a hoop 305. A vacuum generator assembly 307 is disposed on the surface of the connecting plate 306. Suction cup brackets 308 are symmetrically disposed below the connecting plate 306. A plurality of suction cups 309 are provided on the suction cup brackets 308.

The piston end of the cylinder 403 is connected to a floating joint 404, and a release paper upper pressing block 405 is connected to the top of the floating joint 404.

[0066] A release paper lower pressing block 406 corresponding to the release paper upper pressing block 405 is also provided on the cylinder fixing seat 402.

[0067] When the manipulator picking, tearing and attaching mechanism 3 displaces the battery cell return frame 6 to the working area of the release paper removing mechanism 4, the tearing edge 501 of the release paper 5 is placed between the release paper lower pressing block 406 and the release paper upper pressing block 405 by translation. Then, driven by the cylinder 403, the release paper upper pressing block 405 moves downward to tightly press the tearing edge 501 of the release paper on the release paper lower pressing block 406.

[0068] Then, the manipulator picking, tearing and attaching mechanism 3 moves upward to tear off the release paper 5 on the lower surface of the battery cell return frame 6, and then continues to displace the battery cell return frame 6 after removing the release paper 5 to the battery cell conveying line 8 near the workbench cabinet 1, and attaches the battery cell return frame 6 to the surface of the battery cell 7.

[0069] As Figure 6 shown, it should be noted that in this embodiment, battery cell carriers 801 are equidistantly arranged on the battery cell conveying line 8, and the battery cell carriers 801 carry the battery cells 7, so that the attachment of the battery cell return frame 6 can be realized during the conveying process, and the degree of automation is high.

[0070] As Figure 4 and Figure 5 shown, a release paper collecting box 10 is also provided near the release paper removing bracket 401 for recycling the torn release paper 5. The release paper 5 falls into the release paper collecting box 10 below under the action of its own gravity after being torn off.

For those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
