Description

Technical Field

[0001] This utility model relates to the field of screen bonding technology, and in particular to a special fixture for screen bonding. Background Technology

[0002] In the manufacturing process of electronic devices, the bonding between the screen and the back cover or frame usually relies on double-sided adhesive to achieve fixation and sealing. The quality of the adhesion directly affects the product's appearance, structural strength and waterproof performance.

[0003] Traditional screen bonding operations often involve manually applying adhesive to the screen edges by hand. Operators must align the adhesive with the screen border while slowly pressing it in place. This method is highly dependent on worker experience and technique. Because it is difficult for the hands to maintain constant pressure and uniform speed, it is very easy for the adhesive to be applied crookedly, wrinkled, bubbly, or partially detached, resulting in quality problems such as "uneven edges" and "crooked edges," which seriously affects product yield.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] This application provides a special fixture for screen mounting, including: Installation component 1; Positioning component 2 is installed on mounting component 1 via adjustment mechanism 3. At least two adjustment mechanisms 3 are provided. Adjustment mechanism 3 is used to adjust the distance between mounting component 1 and positioning component 2 to accommodate adhesive backing of different widths. Support 4 is installed on mounting 1. Support 4 and positioning 2 are located on the same side of mounting 1. The bottom of support 4 and positioning 2 are on the same plane. Support 4 is provided with at least two mounting mechanisms 5. A support shaft 6 is mounted on the mounting mechanism 5. A pressure roller 7 is rotatably mounted on the support shaft 6. The pressure roller 7 is used to apply pressure to the adhesive backing for adhesion. Through the technical solution of this utility model, the mounting component 1 provides an installation base for components such as the positioning component 2 and the support component 4, laying the foundation for the positioning and application of the adhesive backing. The adjustment mechanism 3 adjusts the distance between the mounting component 1 and the positioning component 2 to adapt to adhesive backings of different widths and specifications, eliminating the need to replace the fixture and greatly improving the versatility of the fixture. The positioning component 2 provides lateral positioning for the adhesive backing, preventing it from shifting left or right during the application process and ensuring accurate application of the adhesive backing to the screen. The support component 4 and the positioning component 2 are on the same plane, ensuring stability during adhesive application. The mounting mechanism 5 provides an installation carrier for the support shaft 6, ensuring the free rotation of the pressure roller 7. The pressure roller 7, which is rotatably mounted on the support shaft 6, applies pressure to the adhesive backing during the application process, improving the tightness and surface flatness of the adhesive backing, and increasing the finished product qualification rate of the screen application operation.

[0019] During use, the installation mechanism 5 includes: The movable part 51 is slidably installed in the inner groove of the support part 4, and the support shaft 6 is installed on the movable part 51; The guide shaft 52 is installed in the inner groove of the support member 4, and the through hole of the moving member 51 is slidably connected to the guide shaft 52; Spring 53 is connected at both ends to support 4 and moving part 51 respectively, and spring 53 is fitted on the outside of guide shaft 52; Through the technical solution of this utility model, the movable part 51 drives the pressure roller 7 to slide flexibly, ensuring the overall adhesion effect of the backing adhesive. The guide shaft 52 provides guidance for the sliding of the movable part 51, preventing the movable part 51 from deviating and shaking when sliding. The spring 53 is fitted outside the guide shaft 52 and its two ends are connected to the support part 4 and the movable part 51 respectively. It uses its own elasticity to provide continuous elastic pressure to the movable part 51, driving the pressure roller 7 to always be tightly attached to the backing adhesive surface. At the same time, the elastic reset function of the spring 53 allows the movable part 51 to automatically reset after a single application, ready for the next screen application operation, improving the convenience of operation.

[0020] In the above embodiment, a threaded post 54 is provided in the threaded through hole of the support member 4, and one end of the threaded post 54 is connected to the spring 53. The other end of the threaded column 54 is configured as a regular hexagonal structure; By adjusting the length of the threaded column 54 extending into the support member 4 through the rotation of the threaded column 54, the pre-compression of the spring 53 is changed, and the elastic pressure applied by the spring 53 to the moving member 51 is flexibly adjusted, thereby realizing the control of the pressure applied by the pressure roller 7 to the adhesive and improving the adaptability of the screen bonding fixture to different adhesives.

[0021] During use, the adjustment mechanism 3 includes: Threaded pipe 31 is installed on mounting component 1; The threaded rod 32 is rotatably installed in the shaft hole of the positioning part 2, and the threaded rod 32 is connected to the threaded tube 31.

The distance between the mounting part 1 and the positioning part 2 is adjusted by the threaded transmission to adapt to the backing adhesive of different width specifications, meet the diverse screen bonding needs, and improve the versatility of the fixture. In at least two adjustment mechanisms 3, the cooperation between the two threaded rods 32 and the threaded tube 31 restrains each other to form a reliable locking structure, which effectively prevents the positioning part 2 from loosening or shifting due to vibration or external force during screen bonding operations. The adjustment cap 33 set at the end of the threaded rod 32 makes it easy for the staff to directly hold and rotate it manually, reducing the difficulty of adjustment operation.

[0022] As a preferred embodiment of the above, the mounting part 1 is provided with a gripping groove, and the gripping groove is provided with a chamfer; Through the technical solution of this utility model, the gripping groove provided on the mounting part 1 provides a force point for the staff to move and adjust the special fixture for attaching the screen, improving the convenience of fixture operation and adjustment. The chamfer provided at the gripping groove effectively eliminates the sharp edges of the gripping groove and improves the safety of operation.

[0023] During use, the bottom of mounting part 1 protrudes beyond the bottom of support part 4, forming a stepped structure; Through the technical solution of this utility model, the stepped structure provides a positioning reference for the fixture, so that the mounting part 1 can be inserted into the step, limiting the screen from shifting during the attachment process and ensuring that the adhesive backing is aligned with the area of ​​the screen to be attached.
