Description

Technical Field

[0001] This invention belongs to the field of 3C high-end manufacturing, specifically relating to an easy-tear adhesive feeding mechanism, a film picking mechanism, and a film tearing device. Background Technology

[0002] With the development of technology, the manufacturing precision and requirements for 3C products (computers, communications, and consumer electronics) are becoming increasingly stringent. For screens or cover plates, the protective film covering their surface needs to be removed during the production and testing process; this process is collectively referred to as film removal.

[0003] Traditional film removal involves manual tearing. This not only easily causes secondary pollution but is also inefficient. Therefore, an automatic film removal device needs to be designed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide an easy-tear adhesive feeding mechanism, a film picking mechanism, and a film tearing device, which can solve the above-mentioned problems.

[0005] An easy-tear adhesive feeding mechanism includes a film feeding roller, a take-up roller, a transmission wheel assembly, a film feeding driver, a film-taking guide block, and a film-pressing module, all mounted on a film feeding frame. A roll of film with easy-tear adhesive attached is replaceably mounted on the film feeding roller. The film-pressing module is vertically mounted above the film-taking guide block, and both the film-taking guide block and the film-pressing module have film-taking guide notches on the same side. The easy-tear adhesive is removed from the film at the film-taking guide notches on the film-taking guide block and the film-pressing module, and the film is then conveyed to the take-up roller for winding.

[0006] Furthermore, the film-taking guide bottom block is horizontally arranged on the outer side of the top of the film supply frame and located downstream of the film supply roller. The film pressing module includes a lifting film pressing driver and a film pressing block. The lifting film pressing driver is arranged on the inner side of the upright plate of the film supply frame. The film pressing module is horizontally fixedly connected to the top of the lifting film pressing driver, and the film-taking guide notch opened in the film pressing block is smaller than the film-taking guide notch opened in the film-taking guide bottom block.

[0007] Furthermore, the first wheel of the transmission wheel set is a material width adjustment wheel, with a scale and a film width adjustment stop on the wheel axle, which matches the output width of the film supply roller.

[0008] Furthermore, the easy-tear label feeding mechanism also includes an easy-tear label feeding slide seat, which includes a sliding top plate, a slide rail module, a sliding bottom plate, and a handle; the film supply frame and the handle are disposed on the sliding top plate.

[0009] The present invention also provides a membrane picking mechanism, which includes a membrane clamping head and a membrane clamping and transfer module; the membrane clamping head includes an easy-tear adhesive rolling module and a membrane clamping module disposed on a membrane clamping base plate, the easy-tear adhesive rolling module and the membrane clamping module being arranged at an angle to each other.

[0010] Furthermore, the easy-tear adhesive roller module includes a roller cylinder, a roller base plate, a roller sliding module, an adhesive roller mounting component, rollers, and an adhesive roller reset module; the adhesive roller reset module is connected to the roller base plate and the adhesive roller mounting component and is used to reset the roller sliding module after roller movement.

[0011] Furthermore, the diaphragm gripping module includes an opening and closing driver, an upper gripper for easy-tear adhesive tape, and a lower gripper for easy-tear adhesive tape; the upper gripper for easy-tear adhesive tape and the lower gripper for easy-tear adhesive tape are mounted on two opening and closing sliders of the opening and closing driver.

[0012] The present invention also provides a film-tearing device, comprising an easy-tear label feeding mechanism and a film picking mechanism as described above, wherein the film picking mechanism picks up the easy-tear label at the film picking guide notch of the easy-tear label feeding mechanism.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the film-tearing device of this application can automatically feed and provide easy-tear stickers, and can also efficiently pick up easy-tear stickers through the film picking mechanism. The whole process is unmanned and intelligent, which is convenient for promotion and application in scenarios involving films in the 3C fields such as mobile phones, tablets, and laptops.
