Electric vehicles are mainly driven by electricity, and the assembly of batteries has become one of the most important links in automobile production. Usually, during the automobile assembly process, a battery grabbing tool is required to grab the battery pack, lift it and transport it to the designated location for installation. The common lifting device uses a motor to drive the drag chain, and the drag chain drives the grabbing device for lifting, but it has the following defects: 1) When the object to be grabbed is heavy, using the drag chain to lift it is easy to cause the drag chain to come off during lifting.

After grabbing the battery pack, it cannot be directly transported to the designated location, and manual transportation is required, which increases labor costs and production time.

[0025] The lifting drive mechanism 2 includes: a servo motor 21, a transmission mechanism 22 and a rotating telescopic mechanism 23. The servo motor 21 is installed on one side of the mobile frame 1. The output end of the servo motor 21 is connected to the transmission mechanism 22. The transmission mechanism 22 is connected to the rotating telescopic mechanism 23. The output end of the rotating telescopic mechanism 23 is connected to the manipulator. The rotating telescopic mechanism 23 is used to lift the manipulator.

[0026] The sliding mechanism 3 includes: a pulley block 31, a driving motor 32 and a rotating gear 33. There are four pulley blocks 31, which are respectively installed at the four corners of the mobile frame 1. The pulley block 31 is provided with a pulley, and the pulley is slidably connected with the guide rail. The driving motor 32 is arranged on one side of the mobile frame 1. The output end of the driving motor 32 is provided with a driving gear, and the driving gear is meshed with the rack; when the driving motor 32 is started, the driving motor 32 can drive the driving gear to rotate, and the driving gear can be meshed with the rack to enable the device to move horizontally along the direction of the rack.

[0027] The mobile frame 1 is provided with a suspension support mechanism 11, which includes a suspension bearing seat 111, a shoulder sleeve 112, a thrust ball bearing 113, a washer 114 and a first nut 115. The mobile frame 1 is fixed with a suspension bearing seat 111, a shoulder sleeve 112 is provided at the top of the rotating telescopic mechanism 23, the shoulder sleeve 112, the thrust ball bearing 113, the washer 114 and the first nut 115 are all passed through by the rotating telescopic mechanism 23, the thrust ball bearing 113 is located above the shoulder sleeve 112, and the thrust ball bearing 113 is The washer 114 is pressed onto the shoulder sleeve 112, and the first nut 115 presses the washer 114 onto the thrust ball bearing 113. After the suspension bearing seat 111 is fixed to the movable frame 1, the thrust ball bearing 113 is locked onto the suspension bearing seat 111 by tightening the nut. The suspension bearing seat 111 is used to support the thrust ball bearing 113. Since the rotating and telescopic mechanism 23 extends into the thrust ball bearing 113, the rotating and telescopic mechanism 23 can rotate relative to the suspension bearing seat 111, and the suspension support mechanism 11 serves the purpose of supporting the rotating and telescopic mechanism 23.

[0028] The rotating telescopic mechanism 23 includes: a telescopic guide cylinder 231, a telescopic rod 232 and a screw 233. The mobile frame 1 is installed with a telescopic guide cylinder 231, and the telescopic rod 232 is slidably connected inside the telescopic guide cylinder 231. A screw hole is provided at one end of the telescopic rod 232, and the screw hole is used to connect with an external manipulator. The screw 233 is threadedly connected in the cavity of the telescopic rod 232, and a first transmission gear 234 is fixed at one end of the screw 233. The first transmission gear 234 is connected to the transmission mechanism 22; when the rotating telescopic mechanism 23 is in operation, the screw 233 rotates in the telescopic guide cylinder 231, and the telescopic guide cylinder 231 can position the screw 233, and the screw 233 will not deviate during rotation.

[0031] The transmission mechanism 22 includes: a connection disk 221, a second transmission gear 223 and a reducer 222. The servo motor 21 is connected to the input end of the reducer 222 through the connection disk 221. The output end of the reducer 222 is provided with a second transmission gear 223. The second transmission gear 223 is meshed with the first transmission gear 234. When the connection disk 221 rotates, it can drive the second transmission gear 223 and the first transmission gear to rotate, thereby causing the screw rod in the rotation-driven telescopic rod 232 to rotate, thereby extending and shortening the telescopic rod 232. The second transmission gear 223 and the first transmission gear are both bevel gear structures.

[0032] A U-shaped rod 6 is installed at one side of the moving frame 1 , and a drag chain 5 is hung at one end of the U-shaped rod 6 . The drag chain 5 is used for sliding guidance of the moving frame 1 .
