Description

Technical Field

[0001] This utility model relates to the field of transmission structure technology, and in particular to a transmission structure used in a fully automatic resistor placement machine. Background Technology

[0002] A pick-and-place machine, also known as a surface mount system, is a piece of equipment in a production line that accurately places surface mount components onto PCB pads by moving a placement head. It primarily handles surface mount components, mostly thick-film chip resistors. Typically, the PCB is placed in a guide rail within the production line for transport and processing at different stages. However, current conventional transport structures offer poor PCB fixation and are inconvenient for angle adjustments, limiting operation during various processing steps. Therefore, we propose a transport structure for a fully automated resistor pick-and-place machine to address this problem. Utility Model Content

The transfer table is slidably mounted on the top of the base, and the rotary table is rotatably mounted on the top of the transfer table. A clamping mechanism is provided inside the rotary table, and a rotation drive mechanism is provided at the bottom of the rotary table.

The rotary motor is fixedly mounted on the top of the transmission table, the drive gear is fixedly mounted on the output shaft of the rotary motor, the drive gear meshes with the internal gear ring, and an annular frame is fixedly sleeved on the outer side of the internal gear ring. The annular frame is fixedly mounted on the bottom of the rotary table.

[0007] The clamping mechanism includes a drive motor and four clamping plates. An L-plate is fixedly installed on the side of each of the four clamping plates that is far apart from each other. A horizontal plate is fixedly installed on the bottom of the L-plate. The horizontal plate is slidably installed inside the rotary table. The drive motor is fixedly installed on the bottom of the rotary table.

[0016] In this utility model, a transmission structure for use in a fully automatic resistor chip mounter is described. By activating an electric push rod, the inclined frame moves to the right. The inclined frame, through its engagement with the inclined hole, moves the clamping plate downward, causing the clamping plate to disengage from the slot and release the lock on the rotary table. Then, the rotary motor is activated, driving the drive gear to rotate. The drive gear, through its meshing with the internal gear ring, drives the rotary table to rotate, thereby rotating the PCB board. This allows for angle adjustment of the PCB board. When the angle required for the corresponding processing step is reached, the rotary motor is stopped, and the output end of the electric push rod retracts, causing the clamping plate to move upward and re-engage into the corresponding slot, thus locking the rotary table and facilitating the chip mounting of resistors on the PCB board.

[0017] This utility model has a reasonable structural design. The rotation drive mechanism facilitates the adjustment of the PCB board angle, and the clamping mechanism fixes the PCB board, which facilitates processing of different procedures and improves flexibility. Attached Figure Description
