[0017] 1. The present invention is provided with a first touch head, a second touch head, a lamp and other components. The touch screen to be tested is placed on the fixture, and the first telescopic cylinder is started. The telescopic rod of the first telescopic cylinder drives the fixture to move toward the rear side.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0032] A touch screen quality testing platform, such as Figures 1-11As shown, it includes a base 101, a mounting frame 102 is fixedly connected to the top surface of the base 101, a fixture for placing the touch screen is provided on the top surface of the base 101, the fixture is driven by a first telescopic cylinder 201 to slide, a finger simulation component for touch detection of the touch screen is provided inside the mounting frame 102, the finger simulation component includes a first touch head 301 and a second touch head 302, the first touch head 301 is provided in the middle of the mounting frame 102, and two second touch heads 302 are provided, and are symmetrically arranged with the first touch head 301 as the center. Both the touch head 301 and the second touch head 302 are pressed downward by the first driving component, and the second touch head 302 is moved closer to or away from the first touch head 301 by the second driving component. A light transmission detection component is provided inside the installation frame 102, and the light transmission detection component is located in front of the finger simulation component. The light transmission detection component includes lamps 401 evenly arranged inside the installation frame 102, a light transmission plate 103 is fixedly connected to the upper part of the base 101 directly below the lamps 401, and a detection board 402 is installed inside the base 101 directly below the lamps 401.

[0033] As can be seen, first, the distance between the second touch head 302 and the first touch head 301 is adjusted by the second driving component. Then, the touch screen to be tested is placed on the jig, and the first telescopic cylinder 201 is started. The telescopic rod of the first telescopic cylinder 201 drives the jig to move toward the rear side. Since the light transmission detection component is located in front of the finger simulation component, the light transmittance of the touch screen is first tested. Through the illumination of the lamp 401 and the reflection of the light transmission plate 103, the detection plate 402 can detect the light transmittance of the touch screen, thereby evaluating the light transmission performance of the touch screen. Then, the first driving component is started. The first driving component causes the first touch head 301 or the second touch head 302 to press downward, and then the first touch head 301 or the second touch head 302 simulates a touch line on the surface of the touch screen, simulating a human finger to perform touch line detection. In this way, through the simulated touch line operation and light transmission performance detection, it can be determined whether the touch response and light transmission performance of the touch screen meet the quality standards, and the quality test result of the touch screen is obtained.

[0034] Furthermore, a first mounting frame 303 is fixedly connected to the middle part of the mounting frame 102, and the first touch head 301 is slidably sleeved on the first mounting frame 303 up and down. The second driving component includes limit plates 304 symmetrically arranged on the left and right sides of the mounting frame 102. The two limit plates 304 are moved away from or approached to each other by a first linear module 306. The first linear module 306 is specifically a driving motor and a bidirectional screw rod, that is, a bidirectional screw rod is rotatably connected in the mounting frame 102, and the bidirectional screw rod is driven by the driving motor to realize rotation. The bidirectional screw rod is threadedly connected to the two limit plates 304. A fixed frame 307 is fixed to the side surface of the limit plates 304 that are close to each other. A second mounting frame 308 is slidably connected in the fixed frame 307. The second touch head 302 is slidably sleeved on the second mounting frame 308 up and down, and the second mounting frame 308 is driven by an electric push rod 309 to realize sliding.

[0035] The first driving component includes a second telescopic cylinder 311 installed in the installation frame 102. A squeezing plate 312 is fixedly connected to the telescopic rod of the second telescopic cylinder 311. A fourth elastic member 313 is provided between the first touch head 301 and the first mounting frame 303 and between the second touch head 302 and the second mounting frame 308. The fourth elastic member 313 is specifically a spring. The tops of the first touch head 301 and the second touch head 302 are rotatably connected to a rolling ball 314. The squeezing plate 312 is provided with a reset groove 3121 and a squeezing protrusion 3122 that cooperate with the rolling ball 314. The reset groove 3121 and the squeezing protrusion 3122 can be used to press the first touch head 301 downward alone, the two second touch heads 302 can be pressed downward, or the first touch head 301 and the second touch head 302 can be pressed downward simultaneously.

[0036] Thus, it can be seen that the first linear module 306 can be used to move the limiting plates 304 away from or closer to each other, thereby adapting to different sizes of fixtures. At the same time, the distance between the second touch head 302 and the first touch head 301 can be adjusted, thereby adapting to touch screens of different sizes. Then, the second telescopic cylinder 311 is started, and the telescopic rod of the second telescopic cylinder 311 drives the extrusion plate 312 to move toward the first touch head 301 and the second touch head 302. Figure 8As shown, if the first touch head 301 needs to be pressed downward, the front squeezing protrusion 3122 of the squeezing plate 312 is brought into contact with the ball 314 on the upper part of the first touch head 301, and then the front squeezing protrusion 3122 squeezes the first touch head 301, causing the first touch head 301 to move downward and squeeze the corresponding fourth elastic member 313, and then the first touch head 301 contacts the touch screen for touch line detection. Since the front part of the squeezing plate 312 is provided with a reset groove 3121, the second touch head 302 is in place at this time. If the two second touch heads 302 need to be pressed downward at the same time, the middle squeezing protrusion 3122 of the squeezing plate 312 is brought into contact with the ball 314 on the upper part of the second touch head 302, and then the middle squeezing protrusion 3122 squeezes the second touch head 302, causing the second touch head 302 to move downward and squeeze the corresponding fourth elastic member 31 3. At the same time, since a reset groove 3121 is provided in the middle, the first touch head 301 is reset by the corresponding fourth elastic member 313. If the first touch head 301 and the second touch head 302 need to be pressed downward at the same time, the rear squeezing protrusion 3122 of the squeezing plate 312 is simultaneously in contact with the rolling balls 314 on the upper parts of the first touch head 301 and the second touch head 302, so that the rear squeezing protrusion 3122 squeezes the first touch head 301 and the second touch head 302 at the same time, causing the first touch head 301 and the second touch head 302 to move downward, thereby squeezing the corresponding fourth elastic member 313. If a zigzag touch is required, the electric push rod 309 is activated, and the electric push rod 309 drives the second mounting frame 308 to slide, thereby causing the second touch head 302 to reciprocate, thereby causing the second touch head 302 to perform a reciprocating zigzag motion on the touch screen.

[0037] Furthermore, the fixture includes a placement frame 202 arranged on the top surface of the base 101, an electromagnet 203 is fixedly connected to the telescopic rod of the first telescopic cylinder 201, and a magnetic member 204 that cooperates with the electromagnet 203 is fixedly connected to the placement frame 202. The magnetic member 204 is specifically a magnet, so that fixtures of different sizes can be easily replaced, and thus can adapt to touch screens of different sizes. Second slides 2021 are provided on the left and right sides of the bottom of the placement frame 202, and a support plate 205 is slidably connected to the second slide 2021. A second elastic member is provided between the support plate 205 and the second slide 2021. 206, the second elastic member 206 is specifically a spring, and a second clamping rod 207 is fixedly provided on the side where the two support plates 205 are away from each other, and a retraction groove 3041 that cooperates with the second clamping rod 207 is provided on the limit plate 304, and a first slide groove 2022 is provided in the placement frame 202 just above the second slide groove 2021, and a splint 208 is slidably connected in the first slide groove 2022, and a first elastic member 209 is provided between the splint 208 and the first slide groove 2022, and the first elastic member 209 is specifically a spring, and a first clamping rod 210 is fixedly provided on the side where the splints 208 are away from each other.

[0038] It can be seen that in order to prevent the transmittance detection from being blocked, the touch screen is placed on the top of the support plate 205. When the telescopic rod of the first telescopic cylinder 201 drives the placement frame 202 to retract backward, the second clamping rod 207 cooperates with the folding groove 3041, that is, the limit plate 304 squeezes the second clamping rod 207, so that the two second clamping rods 207 move away from each other, thereby causing the support plate 205 to be folded into the second slide groove 2021. At the same time, the limit plate 304 will squeeze the first clamping rod 210, so that the two first clamping rods 210 are close to each other, thereby causing the splints 208 to be close to each other, thereby causing the splints 208 to clamp the touch screen from the side, thereby preventing the support plate 205 from affecting the transmittance detection. The second elastic member 206 and the first elastic member 209 can help the support plate 205 and the splint 208 to reset.

[0039] Furthermore, a limiting groove 2023 is provided on one side of the placement frame 202, and a limiting rod 211 is rotatably connected to the limiting groove 2023. A third clamping rod 212 is slidably connected to the side wall of the limiting groove 2023. A third elastic member 213 is provided between the third clamping rod 212 and the placement frame 202. The third elastic member 213 is specifically a spring, and a clamping hole matching the third clamping rod 212 is provided on the limiting rod 211.

[0040] It can be seen that in order to prevent the flat cable on the touch screen from interfering with the detection, after placing the touch screen on top of the support plate 205, the flat cable on the touch screen is placed into the limit groove 2023, and the flat cable is connected to the outside world. At the same time, the limit rod 211 is rotated so that the third clamping rod 212 is clamped into the clamping hole. In this way, the limit rod 211 can limit the flat cable on the touch screen and prevent the flat cable on the touch screen from interfering with the detection.

[0041] Furthermore, a first slide bar 403 is provided on the inner wall of the mounting frame 102, and the first slide bar 403 is moved up and down by a second linear module 404. The second linear module 404 specifically includes a driving motor and a screw, which is the existing technology. The first slide bar 403 is slidably connected to a sliding sleeve 405, and the sliding sleeve 405 is rotatably connected to a mounting sleeve 406, and the mounting sleeve 406 fixes the lamp 401 by a fixing screw 407; a fixed block 411 is symmetrically fixed to the inner wall of the mounting frame 102, and a fixed plate 412 and a second slide bar 413 are provided on a side surface where the two fixed blocks 411 are close to each other, the second slide bar 413 is rotatably connected to the fixed block 411, and the fixed plate 412 is slidably connected to the fixed block 411, and the second slide bar 413 is evenly fixed with a reciprocating screw rod 414, and the fixed plate 412 is slidably connected to the moving block 415, the moving block 415 is threadedly connected to the reciprocating screw rod 414, and the moving block 415 is rotatably connected to a rotating sleeve 416, and a torsion spring is arranged between the rotating sleeve 416 and the moving block 415, one end of the lamp 401 is sleeved in the rotating sleeve 416, and a cam 417 is fixed to the rotating shaft of the rotating sleeve 416, and an inclined plate 418 that cooperates with the cam 417 is symmetrically fixed to the fixed plate 412 with the lamp 401 as the center through a connecting rod; racks 421 are fixed on the left and right sides of the top surface of the placement frame 202, and a side surface of the limit plate 304 that is close to each other is rotatably connected to a gear 422 that cooperates with the rack 421, and the gear 422 is connected to the second slide bar 413 through a synchronous belt component 423. It should be noted that the synchronous wheel in the synchronous belt component 423 and the second slide bar 413 are connected through a connection relationship between a key and a keyway.

[0042] Thus, it can be seen that by starting the second linear module 404, the height between the lamp 401 and the touch screen can be changed to adapt to touch screens of different sizes. When the fixture passes directly under the lamp 401, the rack 421 on the placement frame 202 engages with the gear 422, thereby causing the gear 422 to rotate. The rotation of the gear 422 drives the second slide bar 413 to rotate through the synchronous belt component 423. The rotation of the second slide bar 413 causes the reciprocating screw 414 to rotate. The rotation of the reciprocating screw 414 causes the moving block 415 to move left and right. The movement of the moving block 415 drives the lamp 401 to move left and right. While the lamp 401 moves left and right, due to the cooperation of the cam 417 and the inclined plate 418, the lamp 401 rotates around the rotating sleeve 416 as the center. In this way, the lamp 401 can illuminate the touch screen from different angles, simulating the light transmittance of the touch screen under different lighting conditions, and further improving the comprehensiveness and accuracy of the light transmittance detection of the touch screen.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
