Description

Technical Field

[0001] This utility model relates to the field of touch screen fixture technology, and in particular to a high-precision universal assembly fixture for touch screens. Background Technology

[0002] In the touchscreen manufacturing industry, with the diversification of electronic products, the market demand for touchscreens of different sizes is increasing, and the requirements for the versatility and precision of assembly fixtures are also constantly improving. Existing technologies, such as the published application number 202323273508.2 "A Universal Fixture for Touchscreens," can form a placement slot by combining length positioning posts, width positioning posts, and movable fixture fixing blocks to accommodate touchscreens of different sizes. However, it still has significant shortcomings. It relies on manually tightening the first and second locking screws to fix the position of the fixture fixing blocks, which is frequent, cumbersome, and inefficient. Inconsistent screw tightness can also affect positioning accuracy. Furthermore, relying solely on the L-shaped limiting edge of the fixture fixing block's groove structure for lateral positioning results in poor stability of the touchscreen during assembly, making it prone to displacement due to external interference. Therefore, we introduce a high-precision universal assembly fixture for touchscreens. Utility Model Content

[0003] The main objective of this invention is to provide a high-precision universal assembly fixture for touch screens, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-precision universal assembly fixture for touch screens includes an operating table. Support legs are provided at the four lower corners of the operating table. A controller is located on the left front end of the operating table. Movable slots are provided on the upper left and upper right sides of the operating table. A motor is fixedly installed on the left rear end of the operating table. A bidirectional lead screw is fixedly installed at the output end of the motor. A guide rod is fixedly installed inside the movable slot on the right side. Support plates are movably mounted on the front and rear outer surfaces of the bidirectional lead screw and guide rod via movable blocks. A clamping assembly is provided between the four support plates.

[0006] Preferably, the clamping assembly includes two slide rods, which are arranged in a front-to-back correspondence. Two adjusting clamps are movably mounted on the outer surface of each of the two slide rods. Each of the four adjusting clamps has an L-shaped clamping groove on its facing surface and a T-shaped slot at its upper end. A T-shaped locking block is slidably engaged inside each of the four T-shaped slots. A telescopic connecting handle is provided between each of the two longitudinal T-shaped locking blocks. A limit mechanism is provided at the front end of each of the two front adjusting clamps.

[0007] Preferably, the slide bar is fixedly installed between two transverse support plates.

[0008] By adopting the above technical solution, the slide bar forms a horizontal guiding structure.

[0009] Preferably, the positions of the two adjustment clamps located at the front and the two at the rear correspond to each other.

[0010] By adopting the above technical solution, with corresponding front and rear adjustable clamps, clamping force can be applied to both the front and rear ends of the touch screen simultaneously.

[0011] Preferably, the front part of the bidirectional lead screw passes through the rear part of the operating table and extends into the interior of the movable groove on the left, and the front part of the outer surface of the bidirectional lead screw is rotatably connected to the front wall of the movable groove through a bearing.

[0012] By adopting the above technical solution, low-friction rotation can be achieved through bearings.

[0013] Preferably, the limiting mechanism includes a screw, which is threadedly installed at the front middle of the front adjustment clamp. A limiting block is movably installed at the rear end of the screw via a movable sleeve. A frosted pad is provided on the rear part of the inner surface of the limiting block. A handle is provided at the front end of the screw. Guide blocks are provided at the middle of the left and right ends of the front end of the limiting block. An inner groove is provided at the front of the front adjustment clamp. A through hole is provided at the right end of the adjustment clamp.

[0014] By adopting the above technical solution: rotating the handwheel drives the screw forward, pushing the limit block backward, so that the frosted pad is in close contact with the slide bar surface, and the adjusting clamp is fixed by friction to prevent slippage during clamping. The guide block cooperates with the internal guide groove to restrict the limit block to move only along the screw axis.

[0015] Preferably, the adjusting clamp is movably mounted on the outer surface of the slide rod through a through hole, the through hole is interconnected with the interior of the inner groove, and the inner surface of the frosted pad is tightly fitted to the outer surface of the slide rod.

[0016] By adopting the above technical solution, the rough texture of the frosted pad increases the contact friction with the slide bar, so that the clamp will not shift when fixed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By cooperating with the bidirectional lead screw and guide rod, the distance between the two longitudinal adjustment clamps is realized. Then, the adjustment clamps are manually adjusted laterally along the slide rod. At the same time, through the synchronous linkage of the telescopic connecting rod, the touch screen can be accurately positioned to the required position. The limiting mechanism locks the adjustment clamps by tightly fitting the frosted pad with the slide rod, preventing displacement during assembly, greatly improving the accuracy of touch screen assembly and effectively ensuring product quality.

[0019] 2. The overall spacing of the clamping components is adjusted by a bidirectional lead screw driven by a motor. Combined with the flexible sliding of the adjustable clamp on the slide bar, it can adapt to the clamping requirements of different sized touch screens without the need for frequent clamp replacements. Moreover, the L-shaped clamping slots of the four adjustable clamps are positioned from the corners, making the structure stable and reliable. This reduces the adjustment time for operators and significantly improves the production efficiency and equipment utilization of touch screen assembly. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A high-precision universal assembly fixture for touch screens includes an operating table 1. Support legs 2 are provided at the four corners of the lower end of the operating table 1. A controller 3 is provided at the left front end of the operating table 1. Movable slots 4 are provided at the left and right upper ends of the operating table 1. A motor 5 is fixedly installed at the left rear end of the operating table 1. A bidirectional lead screw 6 is fixedly installed at the output end of the motor 5. A guide rod 7 is fixedly installed inside the movable slot 4 located on the right. Support plates 8 are movably installed on the front and rear outer surfaces of the bidirectional lead screw 6 and the guide rod 7 through movable blocks. A clamping assembly 9 is provided between the four support plates 8.

[0030] In this embodiment, the clamping assembly 9 includes two slide rods 91, which are arranged in a front-to-back correspondence. Two adjusting clamps 92 are movably mounted on the outer surface of each slide rod 91. Each of the four adjusting clamps 92 has an L-shaped clamping groove 93 on its facing surface and a T-shaped slot 94 at its upper end. T-shaped blocks 95 are slidably engaged inside each of the four T-shaped slots 94. A telescopic connecting rod 96 is provided between the two longitudinal T-shaped blocks 95. A limit mechanism 97 is provided at the front end of each of the two front adjusting clamps 92. The slide rods 91 are fixedly installed between the two transverse support plates 8. The positions of the two front and two rear adjusting clamps 92 are corresponding. The front part of the bidirectional lead screw 6 passes through the rear part of the operating table 1 and extends into the interior of the movable groove 4 on the left. The front part of the outer surface of the bidirectional lead screw 6 is rotatably connected to the inner front wall of the movable groove 4 through a bearing.

[0031] Through the above scheme: during operation, the slide bar 91 serves as the sliding track for the adjusting clamp 92. The adjusting clamp 92 can slide on the outer surface of the slide bar 91 and its position can be adjusted as needed to clamp touch screens of different sizes. Four L-shaped clamping slots 93 are used for direct touch screen operation. T-shaped blocks 95 can slide in T-shaped slots 94, providing an installation base for the telescopic connecting rod 96, so that the two longitudinal adjusting clamps 92 can be connected, thereby facilitating simultaneous adjustment of the lateral position. The telescopic connecting rod 96 connects the two longitudinal T-shaped blocks 95 and can extend and retract according to the position changes of the adjusting clamp 92, maintaining the connection without affecting the sliding of the adjusting clamp 92.

[0032] In this embodiment, the limiting mechanism 97 includes a screw 973, which is threadedly installed at the front middle of the adjusting clamp 92. The rear end of the screw 973 is movably mounted with a limiting block 971 via a movable sleeve. A frosted pad 972 is provided on the rear part of the inner surface of the limiting block 971. A handle 974 is provided at the front end of the screw 973. Guide blocks 975 are provided at the middle of the left and right ends of the front end of the limiting block 971. An inner groove 976 is provided at the front of the adjusting clamp 92. A through hole 977 is provided at the right end of the adjusting clamp 92. The adjusting clamp 92 is movably mounted on the outer surface of the slide rod 91 through the through hole 977. The through hole 977 is interconnected with the interior of the inner groove 976. The inner surface of the frosted pad 972 is tightly fitted with the outer surface of the slide rod 91.

[0033] With the above scheme: during operation, rotating the hand crank 974 drives the screw 973 to rotate, thereby controlling the forward and backward movement of the limit block 971, so that the abrasive pad 972 contacts the slide rod 91, increasing the friction and preventing the adjusting clamp 92 from sliding, thus playing a fixing role. The guide block 975 is located on the left and right sides of the front end of the limit block 971 and slides in the inner groove 976 to ensure the stability and accuracy of the movement of the limit block 971.

[0034] It should be noted that this utility model is a high-precision universal assembly fixture for touch screens. During use, the operator starts the motor 5 via the controller 3, driving the bidirectional lead screw 6 to rotate. The movable blocks on the left and right sides will move in opposite directions along the bidirectional lead screw 6 and the guide rod 7, causing the support plate 8 to move synchronously, thereby achieving the overall spacing of the clamping components 9 to adapt to the size of the touch screen. The operator manually slides and adjusts the clamping seat 92, moving it along the slide rod 91 to the precise position at the edge of the touch screen. At this time, the longitudinal adjustment clamping seat 92 is linked through the telescopic connecting rod 96 to ensure synchronous longitudinal positioning. The touchscreen corners are quickly aligned and adjusted. Once in place, the rotary handle 974 rotates the screw 973, causing the limit block 971 to move backward. The frosted pad 972 fits tightly against the surface of the slide bar 91, using friction to lock the position of the adjusting clamp 92. The L-shaped clamping grooves 93 of the four adjusting clamps 92 support and position the touchscreen from the four corners, forming a stable clamping structure. After the touchscreen is assembled, the rotary handle 974 is rotated in the opposite direction to release the limit block 971 from the slide bar 91. The controller 3 reverses the motor 5 to reset the clamping assembly 9, making it easy to remove the finished product and prepare for the next operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
