Description

Method for tearing enveloped sheet

The invention belongs to the technical field of PCB board processing, and particularly relates to a method for tearing off a coated board.

At present, the semi-finished products of PCB boards that are processed are generally covered with two protective films on the upper and lower surfaces, respectively, so as to protect the upper and lower surfaces of the PCB board. When the PCB semi-finished products need to be further processed, just move Just remove the protective film on the upper and lower surfaces of the PCB. The current implementation of tearing off the protective film is generally: manual operation, specifically, when removing the protective film on the upper and lower surfaces of the PCB board, a blade is firstly used to lift an edge of the protective film, and then by a human hand Remove the protective film. However, such an implementation mode is not only inefficient and labor cost intensive, but also easily scratches the surface of the PCB board and / or scratches the protective film when the edge of the protective film is lifted using a scraper, which greatly affects the production schedule.

Therefore, it is necessary to provide a technical means to solve the above defects.

The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for tearing off the coated sheet material, so as to solve the problems of low efficiency, high cost and high cost when tearing off the protective film on the upper and lower surfaces of the PCB in the prior art. Easy to scratch the surface of the PCB board and / or scratch the protective film problem.

The present invention is realized in such a manner, and a method for tearing off the coated sheet material includes preparing a cabinet for installation and installation of each component, a transfer device for transferring the coated sheet material to a designated position, and a method A center positioning device for the coated sheet material on the conveying device toward a center position in the conveying direction of the conveying device, a film lifting device for lifting the protective film of the coated sheet material, and a protective film for the coated sheet material The film release device released before being opened by the film release device, a film removal device for grasping and removing the protective film on the film sheet lifted by the film release device, and buffering the Buffer device for the force generated when the protective film of the coated sheet is removed by the grasping film removing device, and a static electricity removing device for removing static electricity generated between the peeled film sheet and the peeled protective film A film removal detecting device for detecting whether the protective film on the coated sheet is completely removed from the coated sheet, and for collecting the protective film removed from the coated sheet by the grasping film removing device Film collection device, and Electrical control devices controlling the conveying device, the center positioning device, the film lifting device, the envelope releasing device, the grasping film removing device, the buffer device, the film removal detection device and the film collection device; The conveying device, the center positioning device, the film lifting device, the envelope releasing device, the grasping film removing device, the buffer device, the static electricity removing device, the film moving detection device, the film collecting device, and The electric control device is installed on the cabinet to assemble a film tearing device; a feeding area for feeding the coated sheet material to be torn off is arranged on the conveying device, and the coated sheet material is positioned on the conveying device. A central positioning area at a central position in the conveying direction of the device, a tearing film area for removing and tearing off the protective film of the coated sheet material, and a discharging area for discharging the peeled film of the coated sheet material; The coated sheet material to be torn off is placed on the feeding area of the conveying device, and the electric control device controls the conveying device to convey the coated sheet material; the coated sheet material is transmitted to the conveying device through the conveying device. The central positioning area; the central positioning device moves the coated sheet on the central positioning area toward the center of the conveying direction of the conveying device; the conveying device conveys the coated sheet to the tearing area; The film release device releases the protective film of the film sheet on the tear film area; the film release device lifts the film of the film sheet released by the film release device; The film-removing device grasps and removes the protective film of the coated plate lifted by the film-removing device; the buffering device buffers the protective film of the film-coated plate when it is removed by the film-removing device. Force; the static electricity generated between the torn film and the removed protective film is removed by the static electricity removing device; and the film removal detection device detects whether the protective film on the coated plate is completely removed from the film Remove from the board, and if so, hold it The next step; if not, the entire film tearing operation is suspended by the electronic control device; the protective film removed by the scratch film removing device is collected by the film collecting device by the film collecting device; The coated sheet with the protective film removed is transferred to the discharge Area.

The technical effect of the method for tearing the coated sheet of the present invention is that, because the method for tearing the coated sheet of the present invention is mainly based on a cabinet, a conveying device, a center positioning device, a film lifting device, and a film loosening Film tearing equipment consisting of opening device, film removal device, buffer device, static elimination device, film removal detection device, film collection device and electrical control device.

With the adhesive tape, the protective film of the coated sheet can be adhered and lifted, and the surface of the PCB board can be prevented from being scratched. The next step is to remove the entire protective film by the scratch film removal device. Then, the buffer film is used to buffer the protective film of the coated sheet by the scratch film removal device to avoid the force The film sheet has a problem of bending up and down; and then, the removed protective film is destaticized by a static elimination device to eliminate the protective film from being attached to the conveying device due to the effect of static electricity, making it difficult to perform subsequent processing; The film removal detection device is used to detect whether the protective film on the coated sheet is completely removed from the coated sheet; after that, the removed protective film is collected by the film collecting device to remove the protective film's envelope. The board continues to be conveyed to the discharge area through the conveying device. The entire operation is automated, which not only saves labor costs and improves production efficiency, but also better avoids the use of scrapers to lift the protective film that is easy to scratch the PCB in the prior art. Problems with surface and / or scratched protective film.
