[0002] Currently, electronic devices with screens often use adhesive bonding to fix the screen to the housing. The adhesive properties of the adhesive and the airtightness of the electronic device are directly related to the adhesive bonding accuracy. The adhesive can only perform optimally if the relative position of the adhesive and the screen is within a certain error range. Especially for electronic devices with waterproof requirements, the adhesive must achieve a certain bonding accuracy to achieve waterproof performance.

[0003] According to the Chinese patent announcement number CN220163259U, the patent involves an extrusion-bonding adhesive backing device, including a base. Through the cooperation of the electric push rod, the profiling head, the vacuum generator, the pipeline, the cavity, the positioning hole, the positioning column, the suction hole, the compression spring, and the concave plate, the positioning of the adhesive backing and the automatic extrusion-bonding with the product shell can be achieved with high precision. The setting of the guide column facilitates the guiding of the profiling head, and the setting of the rubber head can prevent the positioning column from causing damage to the product shell.

[0004] The above patent does not have a priority pre-treatment function for the product, which results in bubbles and wrinkles when the adhesive and the product are directly pressed together, affecting the pressing quality. In view of this, we propose a quick adhesive pressing and positioning device. Utility Model Content

The linear motor 21 drives the polishing roller 24 to move to remove dirt and dust on the upper surface of the electronic product.

[0027] Embodiment 2

[0028] See also Figure 1-4 On the basis of the first embodiment, the utility model provides a technical solution: preferably, an adjustment mechanism 3 is provided on the base 1, and includes a storage groove 31, the storage groove 31 is opened on the top of the base 1, and slide grooves 32 are opened on both sides of the inner wall of the storage groove 31, and an adjustment plate 33 is slidably connected to the inner wall of the storage groove 31, and the adjustment plate 33 is a triangular structure, and an adjustment roller 34 is attached to the bottom of the adjustment plate 33, and both ends of the adjustment roller 34 are connected to a slide rod 35, and the surface of the adjustment roller 34 is attached to the bottom inclined surface of the adjustment plate 33 to move, so that the adjustment plate 33 is lifted and lowered in the storage groove 31, and the two slide rods 35 are respectively slidably connected to the inner walls of the two slide grooves 32, and the two slide rods 35 are far One end of the adjusting roller 34 slides through the front side of the base 1, and the through ends of the two sliding rods 35 are fixedly connected with an adjusting arm 36. A groove 4 is provided on the top of the base 1, and a splash plate 5 is slidably connected in the groove 4. A spring 6 is elastically connected between the splash plate 5 and the inner wall of the groove 4. The splash plate 5 is adjacent to the cleaning box 25, and the side of the splash plate 5 close to the cleaning box 25 is an inner arc surface structure, which can adapt to the outer surface of the polishing roller 24 and prevent alcohol splashing. The top of the splash plate 5 is an arc surface structure, and a bracket 7 is installed on the back side of the base 1, and a chassis 8 is installed on the bracket 7. An electric push rod is installed in the chassis 8, and the inner rod of the electric push rod movably passes through the bracket 7 and is installed with a sticky plate 9.

[0029] In this embodiment, the electric push rod is controlled to descend, and the adhesive backing is driven to descend and be pressed and fixed with the electronic product for pre-treatment. The micro water pump draws alcohol and sprays it from the nozzle 26, thereby covering and disinfecting the rotating polishing roller 24. The splash guard 5 can also effectively prevent alcohol from splashing. After cleaning and disinfection, the linear motor 21 drives the polishing roller 24 to reset.

[0030] Working principle: open the box cover 27 through the handle 28, and add alcohol disinfectant into the cleaning box 25. The nozzle 26 is connected to the inner wall of the cleaning box 25 through a micro water pump, and the electronic product is placed in the storage slot 31. By pulling the adjustment arm 36, the slide bar 35 is caused to slide on the inner wall of the slide slot 32, and the adjustment roller 34 is driven to move, so that the surface of the adjustment roller 34 fits the bottom inclined surface of the adjustment plate 33, so that the adjustment plate 33 is caused to rise and fall inside the storage slot 31, so as to match the thickness size of different electronic products, and make the top surface of the electronic product flush with the top surface of the base 1. At this time, the linear motor 21 drives the mounting block 22 to move toward the cleaning box 25, so as to move the polishing roller 24, and the rotary motor 23 synchronously drives the polishing roller 24 to rotate, and polishes when passing through the upper surface of the electronic product, so as to better remove the dirt and dust on the upper surface of the electronic product, and perform pretreatment to improve the subsequent back glue pressing. The flatness of the polishing roller 24 is improved. When the polishing roller 24 passes through the top arc surface of the splash plate 5, the splash plate 5 is squeezed to drop into the groove 4, and reset and pop out under the elastic force of the spring 6, thereby prompting the polishing roller 24 to stay between the inner arc surface of the cleaning box 25 and the inner arc surface of the splash plate 5, and adsorb the back glue on the adhesive plate 9. By controlling the electric push rod to drop, the back glue is driven to drop and pressed and fixed with the electronic product. The back glue pressing after pre-treatment and cleaning will not produce bubbles and wrinkles, thereby improving the pressing quality. After the pressing is completed, the electronic product is taken out, and alcohol can be sucked out from the nozzle 26 by a micro water pump, so as to cover and disinfect the rotating polishing roller 24, so as to better remove the dirt and dust remaining in the pre-treatment process. The splash plate 5 can also effectively prevent alcohol from splashing and splashing. After cleaning and disinfection, the linear motor 21 drives the polishing roller 24 to reset, so as to carry out the next back glue pressing operation.
