Description

Technical Field

[0001] This utility model relates to the technical field of mobile phone screen pressing, specifically to a mobile phone screen glass pressing and positioning fixture. Background Technology

[0002] In the manufacturing process of electronic products such as smartphones and tablets, the precision and reliability of screen assembly directly affect the display effect and touch performance of the product. The screen assembly is usually composed of multiple layers such as glass cover, touch layer and display module. Each layer needs to be bonded together with optical adhesive or UV adhesive. During the pressing process, positioning fixtures are required to perform the work.

[0003] Existing mobile phone screen glass pressing and positioning fixtures typically place the housing and screen directly into the pressing frame and clamp them in place. However, they lack a buffering effect on the pressure plate during the pressing process to prevent damage to the screen due to excessive pressing force. Furthermore, it is inconvenient for workers to remove the screen from the pressing frame after pressing, as the operating space is relatively narrow and the performance is not ideal.

[0004] Therefore, we propose a mobile phone screen glass pressing and positioning fixture to solve the problems mentioned above. Utility Model Content

[0023] The positioning assembly 6 includes an L-shaped plate 61 fixedly installed on the rear side of the operating table 1 near the top and a worm gear 62 movably installed through the L-shaped plate 61. A turntable 63 is fixedly installed at the rear end of the worm gear 62, and a worm wheel 64 is engaged at the bottom of the worm gear 62 near the front end. A rotating rod is fixedly installed through the middle of the worm wheel 64. Screws 65 are fixedly installed at both ends of the rotating rod. The external threads on the outer sides of the screws 65 are arranged in opposite directions. A side plate 66 is movably installed at the opposite end of the screws 65. The bottom of the side plates 66 is fixedly installed on the operating table 1, and a threaded sleeve 67 is threadedly installed at the opposite end of the outer side of the screws 65. The screws 65 and the threaded sleeves 67 are manufactured with the same precision to meet the requirements of synchronous rotation and movement. They can drive the positioning plates 4 on both sides to move relative to or in opposite directions, thereby clamping and positioning the shell and screen to be pressed.

[0024] Each threaded sleeve 67 has a sliding plate 671 fixedly installed on its top, and a sliding rod 672 is slidably installed through the sliding plate 671. The left and right ends of the sliding rod 672 are fixedly installed on the adjacent side plates 66, which serves to guide and limit the movement of the threaded sleeve 67, resulting in high stability.

[0025] On the opposite side of the positioning plate 4, near the top, L-shaped rods 41 are fixedly installed. The ends of the L-shaped rods 41 away from the adjacent positioning plate 4 slide through and extend to the outside of the pressing frame 3, and are fixedly installed on the adjacent threaded sleeves 67 respectively, which can drive the positioning plate 4 to move with the adjacent threaded sleeves 67.

[0026] The buffer assembly 9 includes a buffer plate 91 located at the bottom center of the push plate 8 and two hinge rods 92 movably mounted on the top of the buffer plate 91 near the front and rear sides. The hinge rods 92 are arranged left and right, and the upper ends of the hinge rods 92 are movably mounted on the push plate 8. Dampers A93 are fixedly mounted on the bottom of the buffer plate 91 near the four corners. The lower ends of the dampers A93 are fixedly mounted on the pressing plate 7. N-shaped plates 94 are fixedly mounted on the bottom of the push plate 8 near the four corners. Circular rollers 95 are fixedly mounted on the bottom of the inner cavity of the N-shaped plates 94. Trapezoidal blocks 96 are attached to the bottom of the circular rollers 95, which serve as buffers when the pressing plate 7 is pressed, preventing excessive force from affecting the pressing effect.

[0027] Damping springs A931 are fitted on the outer side of the damper A93, and the two ends of the damping springs A931 are fixedly installed on the buffer plate 91 and the pressing plate 7 respectively, which can work with the damper A93 to play a buffering role.

[0028] Each trapezoidal block 96 has a sliding block 961 fixedly installed at the middle of its bottom. The top of the pressing plate 7 is provided with sliding grooves near the four corners. The outer sides of the sliding blocks 961 are slidably installed in the inner cavities of adjacent sliding grooves. Each sliding block 961 has a damper B962 fixedly installed on its outer side. The outer ends of the dampers B962 are fixedly installed on the inner walls of the inner cavities of adjacent sliding grooves. Damping springs B963 are sleeved on the outer sides of the dampers B962. The two ends of the damping springs B963 are fixedly installed on the inner walls of adjacent sliding blocks 961 and sliding groove cavities. The damping effect can be further improved by the cooperation of the dampers B962 and the damping springs B963.

[0029] In this embodiment: During use, the operator can place the housing and screen on the operating table 1, positioning them within the pressing frame 3. After placement, the turntable 63 is rotated, causing the worm gear 62 to rotate. The rotation of the worm gear 62 drives the worm wheel 64 to rotate, which in turn drives the rotating rod to rotate. The rotating rod then drives the screws 65 on both sides to rotate. The rotation of the screws 65 causes the adjacent threaded sleeves 67 to move relative to each other. This relative movement of the threaded sleeves 67, through the adjacent L-shaped rods 41, causes the positioning plates 4 on both sides to move relative to each other, thus clamping and positioning the housing and screen. Once positioning is complete, the operation can be stopped. Rotate turntable 63, and then run hydraulic push rod 20. When hydraulic push rod 20 runs, it will drive push plate 8 to move downward. When push plate 8 moves downward, it will drive pressing plate 7 to move downward, realizing the pressing operation between the shell and the screen. During pressing, the compression damper A93 and damping spring A931 can play a buffering role. At the same time, the circular roller 95 will squeeze the adjacent trapezoidal block 96 to move outward. When the trapezoidal block 96 moves outward, it will squeeze the adjacent damper B962 and damping spring B963 to play a further buffering role, so as to avoid the pressing force being too large and affecting the pressing effect.

[0030] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-3 and Figure 5-6 The pusher assembly 5 includes a pusher plate 51 that fits and is installed on the top of the rectangular cavity and a threaded rod 52 that is fixedly installed at the bottom center of the pusher plate 51. A threaded tube 53 is threaded on the outer side of the threaded rod 52, and a fixing frame 54 is movably installed at the lower end of the threaded tube 53. The top of the fixing frame 54 is fixedly installed on the operating table 1. A driven gear 55 is fixedly sleeved on the outer side of the threaded tube 53 near the lower end, which can drive the pusher plate 51 to move upward, thereby pushing the pressed screen out to the outside of the pressing frame 3 for easy handling by the staff.

[0031] The driven gear 55 is meshed with the driving gear 551 on the rear side, and the top of the driving gear 551 is provided with a servo motor 552. The top of the servo motor 552 is fixedly mounted on the operating table 1, and the output end of the servo motor 552 is fixedly extended through to the outside of the driving gear 551, which can provide power for the rotation of the threaded tube 53.

[0032] Limiting telescopic rods 511 are fixedly installed at the bottom of the pusher plate 51 near the left and right sides, and the lower ends of the limiting telescopic rods 511 are fixedly installed on the fixed frame 54, which serves to guide and limit the movement of the pusher plate 51, so that it can move up and down stably and has high stability.

[0033] In this embodiment: after pressing is completed, the pressing plate 7 can be moved upward to return to its original position and release the clamping and positioning of the screen. At this time, the servo motor 552 can be started. When the servo motor 552 is running, it will drive the threaded tube 53 to rotate. When the threaded tube 53 rotates, it will drive the push plate 51 to move upward under the action of the limit telescopic rod 511 through the threaded rod 52, so as to push the screen out and push it to the outside of the pressing frame 3 for easy picking up by the staff.
