Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, an automatic PCB transferring apparatus includes a movable chassis 1, a lifting device 2 disposed on the movable chassis 1, and a pallet 3 driven by the lifting device 2 to move up and down;

as shown in fig. 2, the lifting device 2 includes a support 21, a motor 22 fixed on the support 21, a driving belt 231, a driving belt 24, two limiting frames 25 fixed on the support 21, and two lifting mechanisms 23, wherein the driving belt 24 is connected to the two lifting mechanisms 23, and the two limiting frames 25 are both disposed on the driving belt 24;

as shown in fig. 3, the lifting mechanism 23 includes a driving rod 232, and lifting units 233 disposed at both sides of the driving rod 232.

Specifically, a moving device is arranged in the moving chassis 1. The moving device in the moving underframe 1 is an AGV commonly used moving device

As shown in fig. 5, the stopper 25 includes a main body 251 fixed to the bracket 21, a stopper 252 disposed on the top of the main body 251, a lower roller 253, and an upper roller 254, and the main body 251 is U-shaped. The upper roller 254 and the stopper 252 are used to catch the upper portion of the driving belt 24, and the lower roller 253 and the bottom of the body 251 catch the lower portion of the driving belt 24, preventing the driving belt 24 from twisting together.
