[0002] The SMT machine, also known as the "mounting machine" or "surface mounting system", is the main equipment in the SMT production line. It is configured after the dispensing machine or screen printing machine. Its basic principle is to use a mechanical device to store a component in a chuck with a suction cup, and then the chuck moves to place the component at the appropriate place on the PCB board, and use another chuck to weld the electrodes to assemble the final product. The SMT machine is widely used in electronics, communications, automobiles, medical and other industries. It is an important equipment to improve the production efficiency and quality of the electronics manufacturing industry, reduce production costs, and improve product stability and reliability. In the use of existing SMT machines, usually one of the main bodies of the SMT machine is A transport body is arranged on the side, and during the operation of the existing SMT machine body, the SMT machine transports the PCB board to be mounted to the working area through the transport body, and accurately positions and fixes it through the positioning device. Then, according to the preset program and parameters, the SMT machine obtains the electronic components to be mounted from the feeder. The feeder usually contains multiple trays, each tray stores one type of components, and the components are sent to the picking position of the mounting head by mechanical or pneumatic means. Next, the mounting head moves to the picking position and picks up the components from the feeder by means of a vacuum nozzle or a mechanical gripper, etc., to ensure that the components are accurately aligned with the pads on the PCB and mount the components.

[0003] In the existing transport body, a support frame and a transmission member are usually included. During specific use, the PCB board to be mounted is placed on the transmission member for transmission, and then transmitted to the inside of the mounting machine body through the transmission member. The transmission member is usually a conveyor belt driven by a motor and a conveyor roller. However, in the existing transmission process, deviations may occur when moving the PCB board, resulting in inaccurate placement of components, thereby affecting the performance and reliability of the entire circuit board.
