Problems solved by technology

[0003] At present, when the whole roll of FPC cover film is unrolled and laser cut, it is often used directly with the winding device to achieve continuous laser cutting. Finally, it will also show an arc-shaped bending state. If it is directly guided by the guide roller and laser cut at this time, it may cause the FPC cover film to be not completely straightened and affect the cutting accuracy of the laser cutting equipment; and the current FPC After the cover film is cut, a small number of cut flexible circuit boards may still be connected with the FPC cover film, resulting in the need for manual removal of these cut flexible circuit boards, which is very inconvenient and increases the labor intensity of the operator At the same time, when the current laser cutting equipment replaces a new roll of FPC cover film, the operator often needs the operator to manually pass the FPC cover film through multiple guide rollers in sequence, which is very inconvenient and cannot quickly install a new roll of FPC cover film To the cutting equipment for cutting processing

Embodiment 1

[0044] Example 1, such as figure 1 , 2 5, 7 and 9, when replacing a new volume FPC cover film, first control the four sets of electric rod 27 elongation so that the upper housing 1 gradually increases, and the upper casing 1 and the lower casing 2 are gradually separated. Open, at this time, the interior of the lower housing 2 is completely exposed, and the upper mounting frame 12 connected to the upper casing 1 is equally increased with the auxiliary guide roller 121 and the first set of cooling guide rollers, followed by the operator The FPC covers the film to the arranging device 35, and then secured to the roller of the mounting table 3 after the upper housing 1 and the lower casing 2 of the upper housing 1 and the lower casing 2, then control the four sets of electric rod 27. Drop, until the upper housing 1 and the lower housing 2 are reinable into a complete bin room, the two sets of the auxiliary guide roller 121 close to the surface of the electromagnetic heating roller 21...

Embodiment 2

[0045] Example 2, such as figure 1 , 2 3, 5, 7, and 9, if necessary, the flexible circuit board is required to separate from the FPC cover film, and the bottom of the hollow guide roller 231 is close to the bottom of the FPC cover film, control the opening of the pump 33 And periodically open the solenoid valve 2314 corresponding to the hollow guide roller 231 such that the suction hole 2311 corresponding to the hollow guide roller 231 produces suction to produce the bottom of the FPC cover film, and when the hollow guide roller 231 is rotated It will generate a force pulled, and the flexible circuit board cut from the FPC cover is automatically pulled out from the FPC cover film to avoid that some flexible circuit boards cannot be separated from the FPC after laser cutting. The air hole 2311 pulled the flexible circuit board and turned to the bottom, and the corresponding solenoid valve 2314 closed, the external air entered the hollow guide roller 231 through some of the suction ...

Abstract

The invention discloses FPC cover film laser automatic cutting equipment which comprises a mounting table, wherein a collecting bin is mounted on one side of the bottom part of the mounting table, a drawer bin is arranged in the collecting bin, an air extracting pump is mounted in the middle of the bottom part of the mounting table, a purifying bin is mounted on the side, away from the collecting bin, of the bottom part of the mounting table, and an activated carbon bag is arranged at the middle position in the purifying bin. According to the FPC cover film laser automatic cutting equipment, an electromagnetic heating roller is firstly controlled to be heated to a preset temperature, a FPC cover film can be temporarily heated to become soft and plastic, then the FPC cover film passes through the space between the two sets of cooling guide rollers containing cooling liquid to be cooled, the FPC cover film can be automatically and rapidly straightened in cooperation with an upper guide roller and a lower guide roller, thus the FPC cover film can be quickly straightened, the FPC cover film can be in a straight and non-bent state under the condition that the FPC cover film is not stressed, and then when the FPC cover film passes through the lower portion of the laser cutting device, the cutting precision of the laser cutting device on the FPC cover film can be fully guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of FPC covering film processing equipment, and is specifically an FPC cover film laser automatic cutting device. Background technique [0002] FPC is an abbreviated circuit board, also known as a soft circuit board or a flexible circuit board, which is predominated with excellent characteristics such as light and thickness, freely bending, and is composed of an insulating substrate and a conductive layer. There may be a binder between the substrate and the conductive layer, since it has a continuous automation, high wire density, light weight, small size, small wiring error, flexibility and elastibility change shape, are widely Applicable to consumer electronics such as digital cameras, watches, laptops, TFT-LCDs, etc. [0003] When the entire volume FPC cover film is expanded and laser cut, it is often used in conjunction with the winding device to achieve continuous laser cutting, but since the FPC cove...
