Description

Technical Field

[0001] This utility model relates to the field of bonding device technology, and in particular to an LED screen protective film bonding device. Background Technology

[0002] In fields such as electronics manufacturing, automotive displays, smart terminals, and industrial control, LED screens are core display components, and their surface protection is crucial to product lifespan and display performance. Protective film application, as a key process in LED screen production and after-sales maintenance, must simultaneously meet three core requirements: no residual bubbles, precise positioning, and no surface scratches.

[0003] To improve efficiency, some production lines use automated lamination equipment. Most of these machines use flat-pressure lamination. When the pressure distribution of the pressure rollers is uneven or the lamination speed is too fast, air can easily be trapped between the film and the screen, forming linear air bubbles. This can easily lead to loose edge bonding, and the poor material deformation during temperature changes can exacerbate the problems of air bubbles and adhesive delamination. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides, for example Figures 1-4 The LED screen protector film bonding device shown includes: a mounting frame 100, with a base plate connected to the bottom of the mounting frame 100; an elastic bearing device 200 mounted on the base plate; an adsorption bonding device 300 disposed above the elastic bearing device 200, used for adsorbing the protective film; a pressing device 400 inserted into the mounting frame 100, used for pushing the adsorption bonding device 300; and a pressure applying device 500 mounted on... On the mounting bracket 100, the pressurizing device 500 is used to pressurize the inner cavity of the adsorption bonding device 300. By placing the LED screen on the elastic support device 200, the protective film is adsorbed onto the adsorption bonding device 300. Under the push of the squeezing device 400, the adsorption bonding device 300 can be pushed to rotate and attach the protective film, so that the protective film starts to adhere from one side of the LED screen, squeezing out the air between the protective film and the LED screen and bonding it, thus making the adhesion between the protective film and the LED screen tighter and improving the yield rate of protective film bonding.

[0016] Specifically, the elastic support device 200 includes: a fixed plate 201, which is fixedly installed on the base plate by a support rod; a support plate 202, which is disposed above the fixed plate 201; and an elastic support mechanism, which is connected between the fixed plate 201 and the support plate 202. The elastic support mechanism includes: a guide rod 203, one end of which is fixedly connected to the support plate 202, and the other end of which is slidably inserted into the fixed plate 201; and a spring 204, which is movably sleeved on the outside of the guide rod 203. The support plate 202 facilitates the support of the LED screen, the fixed plate 201 facilitates the support of the spring 204, the sliding insertion between the guide rod 203 and the fixed plate 201 makes the movement of the support plate 202 more stable, and the compression deformation of the spring 204 facilitates the elastic support of the support plate 202, so that the screen can be elastically pressed when applying the protective film, avoiding damage to the protective film and making the bonding effect better.

On both sides, slots are provided on both sides of the top of the fixed cover 502. The end of the support rod 505 cooperates with the inner cavity of the slot.

Through the connection of the hose, the air collection box 301 is drawn into a negative pressure state to facilitate the adsorption of the protective film. By rotating the support rod 505 to a vertical state and inserting the end of the support rod 505 into the slot, the relative position between the connecting plate and the fixed cover 502 can be supported by the support rod 505, so that the air collection box 301 is kept in a negative pressure state.
