The technical problem to be solved by this application is to provide a cutting device for drainage boards to solve a problem existing in the prior art.

This application's solution to its technical problems is:

A film sticking device, which has mutually orthogonal X, Y, and Z axes, and includes: a positioning plate, the length direction of the positioning plate is parallel to the Y-axis direction, the positioning plate has a positioning groove, and the depth of the positioning groove The direction is parallel to the Z-axis direction; the elastic plate is connected to the side wall of the positioning plate, the Z-axis and the elastic plate are perpendicular to each other, and the elastic plate moves in the Z-axis direction relative to the positioning plate. Elastic deformation; film adhesive, the film adhesive is connected to the elastic plate, when the elastic plate undergoes elastic deformation, the film adhesive extends back into the positioning groove toward the side wall of the elastic plate.

The protective film is attached to the elastic plate through the film adhesive, and the film adhesive extends into the positioning groove toward the side wall of the elastic plate, then the protective film is in the positioning film. When applying the film, the worker holds the positioning plate so that the positioning groove faces the electronic product. , and then change the position of the positioning plate so that the positioning groove is aligned with the electronic product and the screen of the electronic product extends into the positioning groove. In this process, the positioning groove has a limiting effect on the electronic product, which can improve the quality of the protective film and the screen film of the electronic product. Accuracy; when fitting, in order to reduce the generation of bubbles, tilt the positioning plate so that the top of the protective film is first attached to the head of the screen of the electronic product. Under the influence of gravity and the adsorption force during fitting, the protective film can move along the electronic product. The head of the screen of the product gradually moves toward the tail, so that the elastic plate will also be pulled toward the screen direction of the electronic product. Since the elastic plate elastically deforms in the Z-axis direction relative to the positioning plate, the film adhesive can extend into the positioning plate. The slot then adapts to the size of the screen of the electronic product in the positioning slot. During the attachment process, there is a certain suspension between the elastic plate and the positioning plate, so that the protective film can gradually stick to the screen of the electronic product instead of the entire plane.

Since the elastic plate is connected to the outside of the positioning plate, in order to facilitate the elastic deformation of the elastic plate and reduce the obstruction of the positioning plate to the elastic plate, a deformation groove is added, which is equivalent to partially hollowing out the elastic plate. The part adjacent to the deformation groove is more likely to deform.

It also includes a fixing part, and the elastic plate is connected to the side wall of the positioning plate through the fixing part.

Fixings are added to enhance the connection stability of the positioning plate and the elastic plate.

Thereby, the suspended area of the elastic plate is extended as much as possible along the Y-axis, thereby increasing the deformation degree of the elastic plate.

As a further improvement of the above technical solution, the positioning groove is provided with a positioning block, and the positioning block is close to one end of the positioning groove along the Y-axis direction.

As a further improvement of the above technical solution, the positioning plate is provided with a hole body, the hole body extends to the elastic plate, and the hole body is connected with the positioning groove.

When the protective film is completely pasted on the screen of the electronic product, the worker can hold the positioning plate with his thumb and middle finger, and then extend the index finger into the hole, which is convenient for the worker to hold the positioning plate, and the worker's middle finger and thumb can lift the positioning plate at the same time Use your index finger to press the electronic product to facilitate separation of the film device and electronic product.

As a further improvement of the above technical solution, the positioning plate is provided with an escape groove, and the escape groove is connected with the positioning groove.

Since the outer wall of the electronic product has a volume key or a power key protruding toward the outside, an escape groove is provided for the protruding keys to pass through.

As a further improvement of the above technical solution, an extension plate is connected to the positioning plate, and the thickness of the extension plate along the Z-axis direction is smaller than the depth of the positioning groove along the Z-axis direction.

The extension plate is added to facilitate the lifting of the positioning plate, and it is convenient to separate the positioning plate and the electronic product after the film is completed. Since the positioning plate is covered on the screen of the electronic product from top to bottom, the thickness of the extension plate needs to be set to prevent the extension plate from The bottom surface is directly attached to the table, making it impossible to easily lift the positioning plate.
