Description

Technical Field

[0001] The utility model relates to the technical field of screen repair, in particular to a screen separation device. Background Art

[0002] The in-vehicle host AVN is an in-vehicle host that integrates audio, video, and navigation. It is generally equipped with a screen assembly to meet daily control and information display needs.

[0003] Currently, the screen assembly on the AVN is assembled from the back panel components and the touch screen. The method of applying structural glue first and then pressing them together is mainly used to ensure that the two are tightly fitted. If the appearance of the screen assembly is found to be poor during the product production process, the front back panel components and the touch screen need to be separated and then repositioned. In this process, because the screen assembly is bonded with structural glue, the entire assembly needs to be heated to soften the structural glue before separating the two components. Then, the component separation operation is carried out. After heating, the operation must be quick to avoid the curing / hardening of the structural glue affecting the separation of the components. Due to the structural characteristics of the front and back panel components of some products, there are very few force points available to support the touch screen, and there is no equipment or tool to assist. This makes the separation of the components difficult and difficult to start. The operation is prolonged due to the difficulty of the operation, the structural glue hardens, and the touch screen is unevenly stressed. Continuing to forcibly dismantle it will cause damage to the screen. Utility Model Content

[0004] The purpose of the present invention is to provide a screen separation device to solve the deficiencies in the background technology and effectively improve the efficiency of screen separation.

[0022] See Figure 1-Figure 3The present invention provides a screen separation device for separating a touch screen 102 from a back panel component 101 of a mobile device. The mobile device may be an in-vehicle head unit (AVN). The back panel component 101 is provided with multiple mounting holes, and the touch screen 102 is adhered to the back panel component 101 using structural adhesive. The screen separation device includes an upper mold 200, a lower mold 300, and a screw 400. The upper mold 200 is provided with multiple hand screws 201. These hand screws 201 are used to mate with the mounting holes on the back panel component 101 to achieve a fixed connection between the upper mold 200 and the back panel component 101. The mounting holes have external threads to facilitate the installation of the hand screws 201. The lower mold 300 is movably mounted below the upper mold 200. A plurality of first ejector pins 301 are evenly distributed on the bottom. These first ejector pins 301 are used to eject the touch screen 102 from the back panel component 101. The screw rod 400 is vertically mounted on the upper mold 200 and is in transmission connection with the upper mold 200 via a transmission member 401. The transmission member 401 is mounted on the upper mold 200. The end of the screw rod 400 has an ejection end 402. The screw rod 400 is also provided with a hand nut 403. When the hand nut 403 is turned, the ejection end 402 pushes down on the lower mold 300, driving the lower mold 300 downward. When the lower mold 300 moves downward, the first ejection rod 301 ejects the touch screen 102 from the back panel component 101, thereby separating the touch screen 102 from the back panel component 101. In this way, the problem of rapid operation after heating is solved. By using the design of the screw rod 400 and the hand nut 403, the operator can control the moving speed of the lower mold 300, so that after the structural adhesive softens, the screen can be separated at an appropriate speed, avoiding damage to the screen due to too fast or too slow operation, and reducing the risk of damage; it can also solve the problem of difficult operation caused by the small number of force points. The multiple first ejector rods 301 evenly arranged at the bottom of the lower mold 300 can provide multiple support points, so that the touch screen 102 can be evenly stressed, avoiding screen damage due to the small number of force points; finally, it can also improve efficiency. By replacing manual operation with mechanized operation, the efficiency of screen separation can be significantly improved.

[0023] It should be noted that the screw rod 400 here rotates in two directions. The first is clockwise. When the hand nut 403 is rotated clockwise, the upper mold 200 will move toward the hand nut 403 under the drive of the transmission part 401, and the ejection end 402 will move downward relative to the upper mold 200. Then the lower mold 300 will move downward under the action of the ejection end 402, that is, the moving directions of the lower mold 300 and the upper mold 200 are opposite, and the two are away from each other, so that the touch screen 102 is ejected from the back panel component 101 under the action of the first ejector rod 301 of the lower mold 300. Then, the second rotation direction of the screw rod 400 is counterclockwise. When the hand nut 403 is rotated counterclockwise, the upper mold 200 will move away from the hand nut 403 under the drive of the transmission part 401, and the ejection end 402 will move upward relative to the upper mold 200. At this time, the upper mold 200 will gradually approach the lower mold 300, and the two will approach each other. This usually occurs after the touch screen 102 has been ejected from the back panel component 101, thereby restoring the positions of the upper mold 200 and the lower mold 300 to before separation, so as to facilitate the next use.

[0024] Furthermore, the first ejector pins 301 can be positioned in various positions within the lower mold 300, depending on the structure of the back panel element 101. For example, if the openings of the back panel element 101 are primarily located on the left and right sides, the first ejector pins 301 at the bottom of the lower mold 300 can be arranged in two rows, one opposite each of the openings on the back panel element 101. Furthermore, this symmetrical arrangement ensures even force distribution when separating the touch screen 102, preventing damage caused by uneven force. Furthermore, the first ejector pins 301 can be made of a high-strength plastic material, ensuring structural strength without damaging the touch screen 102.

[0025] As a preferred embodiment, a plurality of connecting rods 500 are provided between the upper mold 200 and the lower mold 300, and the lower mold 300 is movably mounted below the upper mold 200 through the connecting rods 500. For example, four connecting rods 500 are provided between the upper mold 200 and the lower mold 300, and these connecting rods 500 are evenly distributed at the four corners of the device. Moreover, a limiting ring 501 is provided on the top of the connecting rod 500, and the limiting ring 501 is located above the upper mold 200. The limiting ring 501 is designed to match the diameter of the limiting rod to ensure that the lower mold 300 does not deviate from the predetermined path during movement, and to prevent the lower mold 300 from moving downward excessively and damaging the touch screen 102. Secondly, the limiting ring 501 can be designed to be rotatable, so that the installation or removal of the limiting ring 501 on the connecting rod 500 can provide greater flexibility and facilitate the adjustment of the maximum threshold value of the movement of the lower mold 300.

[0026] As another preferred embodiment, multiple guide rods 600 are provided between the upper mold 200 and the lower mold 300. Guide truncated platforms 601 are mounted on the guide rods 600 and fixed to the top of the upper mold 200. The provision of the guide rods 600 can conduct the movement of the upper mold 200 and the lower mold 300, preventing the movement trajectory between the two from deviating. Furthermore, the provision of the guide truncated platforms 601 can improve the stability of the guide rods 600, thereby further enhancing the stability of the upper mold 200 and the lower mold 300 during movement.

[0027] As another preferred embodiment, second ejector pins 302 are symmetrically disposed at the bottom of the lower mold 300, and are positioned near the screw rod 400. In other words, in addition to the first ejector pins 301, the bottom of the lower mold 300 also has second ejector pins 302 symmetrically disposed thereon, and the second ejector pins 302 are positioned near the screw rod 400. This design provides additional support points during the separation process, ensuring that the touch screen 102 can be effectively ejected from the back panel component 101 at various locations.

[0028] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
