Description

Film tearing device

The present invention relates to a device for removing a film from a board, particularly a film tearing device.

Conventional boards (such as glass substrates or circuit boards used in liquid crystal displays) generally have a film attached to the board in order to protect it during transportation. When the board is to be used, the The film is torn off. The most traditional way is to tear off the film manually, which is quite labor intensive.

Later, a manufacturer developed a film tearing device to realize automatic film tearing operation. The film tearing device includes a feeding wheel, a tape wound on the feeding wheel, and a clamping block. When the film on the conveyed plate is torn off, first, the feed wheel will descend, causing the tape to contact and stick to the front end of the film, and then, the feed wheel will rise so that the front end of the film follows the The tape moves up to release the surface of the board, and then, the clamp block is moved so that the front end of the film is sandwiched between the tape and the clamp block, and then, the feed wheel and the clamp block are moved backward away from The board can tear the film off the surface of the board. Although this kind of film tearing device can automate the film tearing operation, however, because the tape is an environmentally friendly consumable, and after a period of use, the viscosity will become poor, and it needs to be discarded and replaced. Therefore, the method of using the tape will not only increase the manufacturing cost, but also cause environmental problems that pollute the environment.

Therefore, the object of the present invention is to provide a film tearing device that can overcome at least one disadvantage of the prior art.

Therefore, the film tearing device of the present invention includes a frame unit and at least one film tearing unit.

The suction module has a slide seat movably provided on the swing seat along the axial direction, and at least one suction nozzle provided on the slide seat.

The second driver is disposed on the swing seat and connected to the slide seat. The second driver is used to drive the suction module to move relative to the swing seat between a preparation position and a film suction position. In the preparation position, the suction nozzle is away from the first end, and when the suction module is in the suction mold position, the suction nozzle is adjacent to the first end.

The clamping seat is pivotally arranged on the sliding seat and has a clamping piece with a clamping end.

The third drive is pivotally connected between the sliding base and the clamping base, and the third drive is used to drive the clamping base to swing relative to the sliding base between an unclamped position and a clamping position, when the clamp When the seat is in the unclamped position, the clamping end of the clip is away from the suction nozzle, and when the clip is in the clamping position, the clamping end of the clip is adjacent to the suction nozzle.

The effect of the present invention is that the suction nozzle of the suction module cooperates with the design of the clip of the clip base, and one end of a film on a plate can be effectively torn and clamped from the plate, so In the process of the board being transported along the board transport direction, the film can be automatically torn off completely from the board, and the suction nozzle of the suction module can cooperate with the clip of the clamping base.
