Description

Tilted circuit board processing conveyor

The present invention is related to a processing machine for etching and cleaning a circuit board, and more particularly to an inclined circuit board processing and conveying device for transporting a circuit board for performing the aforementioned etching, cleaning, and the like.

According to the traditional horizontal circuit board etching, cleaning and the like processing conveyor, usually directly placed on the circuit board to be processed, and through the processing conveyor set a plurality of horizontally lying and spaced rows of rollers The shaft is driven to continuously feed the circuit board forward in a predetermined horizontal path, and the board is etched or cleaned by the circuit board when passing the horizontal route.

However, in the above-mentioned conventional horizontal processing conveyor, when the circuit board is driven, the plurality of rollers provided on the plurality of roller shafts are mainly rotated to push the circuit board forward. However, since the circuit board itself still has a certain weight, and there is a certain distance between the roller shafts, it is impossible to completely ensure that the circuit board maintains a completely horizontal state during the entire conveying process, and the circuit board is often easily made. During transportation, the leading edge of the circuit board is slightly downwardly placed at the distance between the rollers due to the influence of gravity. Thus, the rear roller is pushed forward continuously, which is likely to cause the edge of the circuit board to abut the roller and cause creases. Or even causing the edge of the board to be bitten into the distance between the two rollers and away from the predetermined horizontal conveying route, eventually causing the circuit board to fail to perform the processing smoothly and even being damaged.

In view of this, the creator is trying to improve and solve the above-mentioned shortcomings, and he has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

The main purpose of the present invention is to provide a tilted circuit board processing and conveying device, which mainly transmits air through the air, and at the same time makes the circuit board tilted during transportation, thereby reducing the possibility that the circuit board may be caused during processing. Unnecessary contact and other issues.

In order to achieve the above object, the present invention provides a tilted circuit board processing and conveying device for transporting a circuit board; comprising a base, a plurality of roller assemblies, and a gas supply unit; wherein the base is formed by a long space a transport path for the circuit board to travel, each roller assembly is arranged along the transport path on the lower side of the base, and the base has a surface corresponding to the transport path, the surface is inclined and The air distribution unit is provided with a plurality of air supply holes, and the air supply unit provides air blowing to each air supply hole and faces the conveying path, so as to generate an air floating effect when the circuit board passes through the conveying path, thereby achieving the above purpose.

The assembly 2 is rotated on the base 1 so that the circuit board 6 placed on the roller assemblies 2 can be transported along the transport path 10. Each of the roller assemblies 2 can include a roller shaft 20 laterally pivoted on the base 1, a roller 21 fixed to the roller shaft 20, and an oval 22 located outside the roller 21. In addition, on the other side of the base 1 (ie, on the higher side), the roller assemblies 2 may be arranged along the transport path 10, and the roller assemblies 2 are mounted on the roller shaft 20 The roller 21 is mainly composed, and of course, the oval 22 can be further included.

Please refer to the second figure, the main purpose of the present invention is to provide the gas supply unit 3 under the susceptor 1 to provide an upward gas blowing under the susceptor 1 to make the circuit pass through the susceptor 1. The plate 6 can be floated by the effect of the gas blowing and floating during the process of being conveyed, thereby reducing unnecessary contact with various parts or parts of the conveying equipment during the processing and conveying.
