Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a high-efficiency feeding mechanism of a coating machine. Background Art

[0002] In the manufacturing process of printed circuit boards, a coating machine is required to first coat the substrate with ink, then transfer the coated substrate to an oven for drying, and then undergo an exposure and development process to reveal the circuit layout on the substrate. The structure of the coating machine mainly includes input rollers, coating rollers, liquid receiving devices, drying devices, control panels and other parts.

[0003] When loading existing coating machines, most of them manually pick up the PCB boards on the shelves and place them on the input rollers. The loading speed depends on the manual placement speed. When the personnel are tired, the speed of taking the PCB boards will also decrease. In addition, there is a certain time interval when the PCB boards on a single shelf are coated and a new shelf is taken. During this time, the coating machine is idle, resulting in a decrease in the coating rate of the PCB boards. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency feeding mechanism for a coating machine to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-efficiency feeding mechanism for a coater comprises an input roller assembly for a coater, an adjusting assembly is fixedly mounted at one end of the inner side of the input roller assembly for the coater, the adjusting assembly comprises a slide rail, a bidirectional screw is rotatably connected inside the slide rail, nuts are symmetrically screwed and connected on the outer sides of the bidirectional screw, clamping assemblies are symmetrically fixedly mounted at one end of two nuts, the clamping assembly comprises an extension plate fixedly connected to the nuts, a No. 2 motor is fixedly embedded and mounted on the surface of one side of the extension plate, a rotating plate is fixedly mounted on the output end of the No. 2 motor, bearings are fixedly embedded and mounted at the four corners of the surface of one side of the rotating plate, a roller is fixedly mounted on the inner ring of the bearing, and a conveying assembly is movably provided on one side of the input roller assembly for the coater.

The No. 3 motor is operated to drive the roller to rotate and push the PCB board to move up. Then the No. 2 motor rotates to drive the rotating plate to rotate, so that the PCB board rotates and pushes the PCB board to move to the top of the coating machine input roller assembly to complete the loading. The shelf is placed on the conveying assembly manually, and then the PCB board in the shelf is clamped by the clamping assembly, and the PCB board is automatically placed on the coating machine input roller assembly, replacing the manual picking of a single PCB board for loading, speeding up the loading speed.
