Automatic flattening module

Abstract

The invention discloses an automatic flattening module. The automatic flattening module comprises a workbench, a linear sliding rail, an air cylinder, a follow-up plate, a drag chain, carrier modules,synchronous wheel modules, a hot air gun assembly and a limiting assembly. The linear sliding rail and the air cylinder are installed on the workbench. A follow-up plate is fixed on a sliding block of the linear sliding rail, and a telescopic rod of the air cylinder is fixed with the follow-up plate. The follow-up plate is driven by the cylinder to slide horizontally. One end of the follow-up plate is connected with the workbench through the drag chain. Two sets of carrier modules are installed at the upper end of the follow-up plate, and the carrier modules are respectively driven by synchronous wheel modules at the two sides of the carrier modules to rotate. The hot air gun assembly is arranged at the lower end of the workbench and sequentially penetrates through the workbench and the follow-up plate to be opposite to the carrier modules, and a limiting assembly opposite to the follow-up plate is further arranged on the workbench. In this way, automatic positioning is achieved, thetwo sets of carrier modules are synchronously overturned and flattened, the flattening effect is uniform, the flattening effect is stable, the yield is high, the reliability is high, and products cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, in particular to an automatic flattening module. Background technique [0002] At present, various electronic products, such as smart phones and tablet computers, are developing in the direction of thinner and thinner or can be rolled up, so circuit soft boards, that is, flexible circuit boards, have been more and more widely used. For different processing, coating, assembling components or other purposes, the flexible board needs to be baked. Since the circuit flexible board itself does not have enough strength, the initial state of the circuit flexible board is generally at an angle of about 60 degrees. If the clamping is not firm enough or not flattened, problems such as unevenness, wrinkles and dents will occur on the surface of the soft board after baking, resulting in defective products and waste products. Based on the above defects and deficiencies, it is necessary The techno...

[0002] At present, various electronic products, such as smart phones and tablet computers, are developing in the direction of thinner and thinner or can be rolled up, so circuit soft boards, that is, flexible circuit boards, have been more and more widely used. For different processing, coating, assembling components or other purposes, the flexible board needs to be baked. Since the circuit flexible board itself does not have enough strength, the initial state of the circuit flexible board is generally at an angle of about 60 degrees. If the clamping is not firm enough or not flattened, problems such as unevenness, wrinkles and dents will occur on the surface of the soft board after baking, resulting in defective products and waste products. Based on the above defects and deficiencies, it is necessary The technology is improved and an automatic flattening module is designed

[0003] For example, the Chinese patent document CN203968492U discloses a flattening device for a thin plate frame, including two horizontal bars and side bars arranged in a rectangular shape, and four flexible plate clamps are arranged at the four ends of the two horizontal bars. The board clamp clamps the four corners of the circuit flexible board, and the lifting cylinder group is used to control the closing and opening of the flexible board clamp. However, the position of the flexible board clamp in this document is fixed, and it can only be made 1-2mm parallel to the direction of the side bar. Displacement to exert a flattening force on the circuit flexible board, so it can only flatten the circuit flexible board in one direction, and cannot make the circuit flexible board be flattened in the direction perpendicular to the flattening force, nor It is impossible to eliminate wrinkles or dents in the direction perpendicular to the flattening force, so it is impossible to truly flatten the entire circuit soft board
