Description

A vacuum adsorption film neatening device

Technical field

The utility model relates to the product packaging industry, in particular to a vacuum adsorption film neatening device.

Background technique

The adsorption film device currently in use has a problem that the adsorption film will deform due to negative pressure during the adsorption process. If it is directly attached to the product surface, it will not completely cover the product surface and will generate bubbles. Such protection The manner is unacceptable.

Patent document CN205381440U discloses a vacuum adsorption film sticking device. Mobile phones are usually manually applied with protective films. Because it is a manual operation, it is time-consuming and labor-intensive, and the production efficiency is low. The fitting accuracy cannot be guaranteed, and it is easy to stick to the wrong side, even during the sticking process. Bubbles are produced.

The specific method is to use the empty adsorption plate based on the product outline, open the vacuum adsorption plate, put the protective film on the inner surface of the vacuum adsorption plate, adsorb the protective film through vacuum, adjust the position of the film with the vacuum switch, and put the product to be filmed into After positioning the mold cavity and closing the flip cover, the magnetic sensor senses that it is closed in place and the vacuum switch is turned off. The front and rear adjustable linear guide rails. After the vacuum is turned off, pull the handle to pull out the positioning cavity. The roller of the vacuum adsorption plate will crush the positioning cavity to drive away the air bubbles between the protective film and the product. When the positioning cavity is pulled out, After it comes out, the film sticking process is also completed. This film application device can achieve rapid and accurate alignment. Through the outline of the protective film, it can quickly and accurately align the protective film to achieve rapid film application. There is a rubber layer outside the roller, and the roller rolls the protective film to effectively avoid the generation of bubbles. The operation is simple and efficient, but the disadvantage is that it does not solve the problem of alignment and flatness.

Patent document CN206171909U discloses an adsorption film sticking mechanism, which solves the problem that in the production process of electronic product display screens, a protective film is required on the screen surface to achieve the purpose of protection. During the film application process, attaching the protective film to the screen surface quickly and accurately without generating bubbles is the key to ensuring film quality.

The first end substrate of the lamination through the adsorption and lamination substrate is also equipped with a bubble extrusion roller and a lifting cylinder that drives the bubble extrusion roller to move up and down; when the adsorption lamination substrate moves to the lamination station to laminate, the lifting cylinder drives The bubble squeezing roller moves downward, compresses the protective film and the component to be pasted on the film pasting station, squeezes out the bubbles between the protective film and the component to be pasted, and improves the quality of film pasting. Its shortcoming is that it does not solve the problem of adsorption and lamination. Flat problem.

In view of the shortcomings of existing technology, new technological breakthroughs are urgently needed to tidy up the adsorption membrane.

As shown in Figures 1 and 2, the vacuum adsorption film alignment device includes a drive motor 1, a vacuum generator 2 and an alignment plate 3. This application is only one link during product coating. In this link, the position of the adsorption film changes. , for the reset problem, the driving motor 1 can first set the speed and rotation angle. The driving end of the driving motor 1 is connected to the vacuum generator 2, that is, the driving motor 1 drives the vacuum generator 2 to rotate. The vacuum generator 2 is used to create negative pressure. The vacuum generator 2 is provided with an adsorption block 21 for adsorption. The adsorption block 21 is internally connected to the vacuum generator 2. There are holes evenly arranged on the adsorption block 21. Under the action of the vacuum generator 2, the adsorption block 21 can adsorb The film used to cover the product, the adsorption block 21 is parallel to the alignment plate 3 in the alignment state. At this time, the width of the adsorption block 21 is narrower than the width of the adsorption film, so that excess adsorption film will be displayed on both sides of the adsorption block 21. By bringing the adsorption film close to the alignment plate 3, the adsorption film is flush with the bottom of the adsorption block 21, and the adsorption film is also called a covering film.

A connecting plate 4 is provided between the driving motor 1 and the vacuum generator 2. The two ends of the connecting plate 4 are respectively connected to the driving motor 1 and the vacuum generator 2. The angle between the connecting plate 4 and the driving motor 1 can be adjusted. , at the same time, the angle between the connecting plate 4 and the vacuum generator 2 can be adjusted. By adding the connecting plate 4, one can extend the working distance of the vacuum generator 2, and the other is that the angle of the vacuum generator 2 can be better set without being driven. Motor 1 limit.

The vacuum generator 2 is provided with a vacuum tube 22 for connection. This vacuum tube 22 can be made of stainless steel to prevent it from rusting over time. Both ends of the vacuum tube 22 are connected to the vacuum generator 2 and the adsorption block 21 respectively, because the vacuum tube 22 can help the adsorption block. 21 works over extended distances, and the vacuum tube 22 is retractable on the vacuum generator 2, that is, it can be retracted into the inside of the vacuum tube 22, depending on the height of the product to be covered.

A bracket 31 is provided at the bottom of the alignment plate 3 for support. Also in order to match the height of the adsorption block 21, the alignment plate 3 can be raised and lowered on the bracket 31.

The length of the alignment plate 3 is longer than the length of the adsorption block 21, because if it is shorter, the covering film adsorbed by the adsorption block 21 will not be stressed by the alignment plate 3. In this way, the covering film cannot be completely reset in the adsorption block 21, and the covering film will not reach the required height. to achieve a flush effect.

An adsorption strip 23 is provided at the bottom of the adsorption block 21 to match the adsorption film. The adsorption strip 23 is narrower than the top of the adsorption block 21. An adsorption strip 23 is added below to make the adsorption force stronger. The bottom of the adsorption strip 23 is completely flush and has no The concave and convex adsorption strips 23 are available in various sizes to meet the products to be covered with different widths.

The principle is as follows:

When the adsorption strip 23 adsorbs the covering film or adsorption film, the covering film or adsorption film is adsorbed by negative pressure. During this process, it is displaced and cannot be completely flush with the bottom of the adsorption strip 23. For example, the bottom plane of the adsorption strip 23 is rectangular. The attached covering film or adsorption film is also rectangular, but the adsorbed covering film or adsorption film cannot keep the edges of the bottom surface of the adsorption strip 23 parallel, forming a misalignment. The driving end of the drive motor 1 drives the vacuum generator 2 to rotate, driving the adsorption strip 23 to also Rotation occurs until it is in parallel contact with the alignment plate 3, so that the attached covering film or adsorption film on the side close to the alignment plate 3 is stressed and completely flush with the bottom edge of the adsorption strip 23, thus satisfying the problem to be solved.

The above embodiments are only for illustrating the technical concepts and characteristics of the present utility model. Their purpose is to enable those familiar with this technology to understand the contents of the present utility model and implement it accordingly. This does not limit the scope of protection of the present utility model. Equivalent changes or modifications based on the spirit and essence of the present utility model shall be included in the protection scope of the present utility model.
