[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a technical solution: a mechanism for facilitating batch testing of touch screens, comprising: a testing platform 1, with support legs 101 fixedly connected to the four corners of the bottom of the testing platform 1, hinges 102 fixedly connected to both ends of the two sides of the inner cavity of the testing platform 1, the four hinges 102 forming a group of two, the other end of the two groups of hinges 102 fixedly connected to a closing door 103, the other end of one side of the two closing doors 103 fixedly connected to a handle 104, multiple placement platforms 105 fixedly connected at equal intervals on the top of the testing platform 1, clamping plate moving grooves 106 extending through the top of the testing platform 1 at the positions on both sides of the multiple placement platforms 105, limiting grooves 107 formed on both sides of the inner cavity of the multiple clamping plate moving grooves 106, a fixed platform 108 and multiple support plates 109 fixedly connected to the bottom of the inner cavity of the testing platform 1, clamping components 2 provided in the inner cavity of the multiple clamping plate moving grooves 106, and a driving component 3 provided on the top of the fixed platform 108.

[0025] Specifically: After setting the clamping pressure of the intelligent hydraulic cylinder 301 through an external controller, the intelligent hydraulic cylinder 301 is activated. Multiple sets of clamping plates 204 follow multiple sets of driven moving blocks 203 to move inward to clamp and fix the touch screens placed on the surfaces of multiple placement platforms 105. This design uses one intelligent hydraulic cylinder 301 to drive multiple clamps, reducing costs. Since the toothed groove 304 and gear 307 are meshed, multiple limit rods 303 can be forced to move up and down synchronously, causing multiple drive plates 208 to move up and down synchronously. This design allows the mechanism to reduce dynamic response delay.

[0026] In one embodiment, the clamping assembly 2 includes a plurality of U-shaped fixing plates 201. Both ends of the inner side of the plurality of U-shaped fixing plates 201 are provided with misalignment grooves 202. The interior of the plurality of misalignment grooves 202 is movably fitted with driven moving blocks 203. One side of the plurality of driven moving blocks 203 is set with an incline. The top of the plurality of driven moving blocks 203 is fixedly connected with a clamping plate 204. One side of the plurality of clamping plates 204 is fixedly connected with a clamping pad 205.

[0027] Specifically, as shown in the figure: the misalignment slot 202 provides misalignment space for the moving driven moving block 203.

[0028] In one embodiment, limit blocks 206 are fixedly connected to the bottom of both sides of the multiple clamping plates 204, and T-slots 207 are provided on one side of the multiple driven moving blocks 203. Two opposite T-slots 207 form a group, and drive plates 208 are movably fitted into the inner cavity of the multiple groups of T-slots 207. Push-pull rods 209 are fixedly connected to the bottom of the multiple drive plates 208, and the surfaces of the multiple push-pull rods 209 are movably fitted into the inner cavity of the bottom of the multiple U-shaped fixed plates 201.

[0029] Specifically, as shown in the figure: the push-pull rod 209, which moves up and down, pushes or pulls the drive plate 208 to move up and down. Since the two ends of the drive plate 208 are movably fitted into the inner cavity of the inclined T-slot 207, when the drive plate 208 moves down, it pulls the two driven moving blocks 203 to move inward. When the drive plate 208 moves up, it pulls the two driven moving blocks 203 to move outward. The driven moving blocks 203 drive the clamping plate 204 to clamp the touch screen.

[0030] In one embodiment, the drive assembly 3 includes an intelligent hydraulic cylinder 301. A push-pull plate 302 is fixedly connected to the top of the intelligent hydraulic cylinder 301. A plurality of limit rods 303 are fixedly connected to the bottom of the push-pull plate 302. A plurality of toothed grooves 304 are formed on the surface of each of the limit rods 303. A sleeve 305 is movably fitted on the surface of each of the limit rods 303. The bottom end of the intelligent hydraulic cylinder 301 is fixedly connected to the top of the fixed platform 108.

[0031] Specifically, as shown in the figure: the sleeve 305 and the limiting rod 303 are set to be relatively long, which not only meets the needs of use, but also ensures that the limiting rod 303 is always partially embedded inside the sleeve 305, no matter how the push-pull plate 302 moves up and down; the intelligent hydraulic cylinder 301 is a commonly used hydraulic cylinder with an integrated pressure sensor installed. The integrated pressure sensor is usually located in the piston chamber or rod chamber oil port and is often used for precision pressure control.

[0032] In one embodiment, a through groove 306 is provided on the surface of a plurality of sleeves 305, and a gear 307 is meshed with the surface of a plurality of toothed grooves 304 corresponding to the through groove 306, and a rotating shaft 308 is fixedly embedded in the center of the plurality of gears 307.

[0033] Specifically, as shown in the figure: the through groove 306 provides meshing connection space for the tooth groove 304 and the gear 307.

[0034] In one embodiment, the tops of both ends of a plurality of U-shaped fixing plates 201 are fixedly connected to the top of the inner cavity of the test platform 1, the surfaces of a plurality of clamping plates 204 are correspondingly and movably fitted into the inner cavity of a plurality of clamping plate moving grooves 106, and the surfaces of a plurality of limiting blocks 206 are correspondingly and movably fitted into the inner cavity of a plurality of limiting grooves 107.

[0035] Specifically, as shown in the figure: the clamping plate 204 is movably fitted and embedded in the inner cavity of the clamping plate moving groove 106, and the surface of the limiting block 206 is movably fitted and embedded in the inner cavity of the limiting groove 107, thereby restricting the movement of the clamping plate 204 and the limiting block 206 and ensuring the realization of the clamping function.

[0036] In one embodiment, the surface of the rotating shaft 308 is mounted on the top of a plurality of support plates 109 by bearings, and the bottom ends of a plurality of sleeves 305 are fixedly connected to the bottom of the inner cavity of the test platform 1.

[0037] Specifically, as shown in the figure: the bottom end of the intelligent hydraulic cylinder 301 is fixedly connected to the top of the intelligent hydraulic cylinder 301 to mechanically constrain the intelligent hydraulic cylinder 301.

[0038] Working principle: Connect the touch screen testing mechanism to an external power supply to provide power to the mechanism. The external controller is associated with the intelligent hydraulic cylinder 301 for control. In the initial state, the output end of the intelligent hydraulic cylinder 301 is in the longest extension state.

[0039] The touchscreen to be tested is placed on the surface of the placement platform 105. After the clamping pressure of the intelligent hydraulic cylinder 301 is set by the external controller, the intelligent hydraulic cylinder 301 is activated. The output end of the intelligent hydraulic cylinder 301 retracts, and the push-pull plate 302, multiple push-pull rods 209 and multiple drive plates 208 move downward with the intelligent hydraulic cylinder 301. When the multiple drive plates 208 move downward, two opposite driven moving blocks 203 form a group, and two opposite clamping plates 204 form a group. The multiple groups of driven moving blocks 203 are pulled inward, and the multiple groups of clamping plates 204 follow the multiple groups of driven moving blocks 203 to move inward, clamping and fixing the touchscreen placed on the surface of the multiple placement platforms 105. Then, the external testing equipment can be used to perform subsequent touchscreen testing operations.

[0040] This design uses a smart hydraulic cylinder 301 to drive multiple fixtures, reducing costs and facilitating batch testing of touchscreens.

[0041] While the intelligent hydraulic cylinder 301 pushes or pulls the push-pull plate 302 to move up and down, the limiting rod 303 embedded in the inner cavity of the sleeve 305 moves up and down accordingly. However, since the push-pull plate 302 has a certain length, the limiting rod 303 may not move up and down synchronously. Since the tooth groove 304 and the gear 307 are meshed, multiple limiting rods 303 can be forced to move up and down synchronously, so that multiple drive plates 208 are forced to move up and down synchronously.

[0042] This design allows the mechanism to reduce dynamic response latency.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
