Technical Field

[0001] The utility model relates to the technical field of battery pack disassembly, and in particular to an anti-dropout connecting rod structure of a coil grabbing device. Background Art

[0002] New energy vehicle battery packs are an important component for storing electrical energy for use in electric vehicles. They are usually composed of multiple batteries, which can be lithium-ion batteries, lithium cobalt oxide batteries, etc.

[0003] Lithium batteries contain harmful substances inside. If they are discarded directly after use, it will harm the environment. Therefore, after lithium batteries are used, they are usually recycled and disassembled to collect the recyclable substances in the lithium batteries. When the battery pack is disassembled, a manipulator is needed to grab the battery pack. The existing manipulator is driven by a cylinder to drive the clamp. The telescopic end of the cylinder and the top of the clamp are simply hingedly connected by a single connecting rod. When grabbing the battery pack, the grabbing effect of the battery pack is poor and it is easy to cause it to loosen. Therefore, we proposed an anti-drop connecting rod structure for coil grabbing equipment to solve the above problem. Utility Model Content

[0021] Among them, a connecting block 16 is installed at the telescopic end of the cylinder 11, and an axle pin 14 is arranged in the connecting block 16. The axle pin 14 is arranged horizontally, and the axle pin 14 slides with the housing 1 in the up and down directions. Limiting grooves 18 are provided on both sides of the housing 1. The two ends of the axle pin 14 are respectively inserted into the limiting grooves 18 on both sides, and a protective groove 19 is provided on the outer side of the limiting groove 18. The left and right directions of the axle pin 14 are limited by the limiting groove 18;

[0022] Two connecting rod pieces 15 are arranged on both sides of the axle pin 14, and the connecting rod pieces 15 are rotatably connected to the axle pin 14 through bearings, and the outer ends of the two connecting rod pieces 15 on the same side are rotatably connected to the top end of a clamping jaw 12. Through the operation of the cylinder 11, the connecting rod piece 15 can drive the two clamping jaws 12 to clamp and close. At the same time, a limit block 20 is arranged inside the shell 1, and the limit block 20 is located below the connecting block 16, and the height of the limit block 20 is lower than the top end of the clamping jaw 12. The limit block 20 limits the downward stroke of the cylinder 11, thereby improving the stability of the two clamping jaws 12 after closing.

[0023] It should be noted that sliders are installed at the bottom of both ends of the shell 1, and limit pins are set below the sliders. The limit pins are slidably connected to the shell 1.
