Description

Technical Field

[0001] The present invention relates to the technical field of touch screen detection, and particularly to a touch screen quality detection platform. Background Art

[0002] A touch screen is a display technology that enables interaction with an electronic device through touch input. It senses the position of the touch points on the surface of the touch screen and then realizes the control of device operations. Touch screens are widely used in devices such as smart phones, tablet computers, ATMs, ticket vending machines, or car navigation systems. During the production of touch screens, in order to ensure product quality and improve user experience, it is usually necessary to detect the touch screens.

[0003] Existing detection technologies, for example, the patent with the authorization announcement number CN217467061U discloses a touch screen detection device. Although this detection device can meet the requirements of simulating the operation of one finger to multiple fingers on the touch screen at the same time, this patent can only simulate the straight-line movement of fingers and cannot simulate complex gestures under multi-touch, such as multiple fingers moving along different trajectories on the screen. At the same time, this patent can only complete the touch detection of the touch screen. After the touch detection is completed, the touch screen needs to be moved to another detection device for testing. For example, light transmittance detection is also required, and the two need to be carried out separately, increasing the test time and workload. In view of this, the present invention provides a touch screen quality detection platform, which solves at least one of the above-mentioned technical problems. Summary of the Invention

[0013] The present invention has the following advantages: 1. The present invention is provided with components such as a first touch head, a second touch head, and a lamp. The touch screen to be detected is placed on the jig, the first telescopic cylinder is started, and the telescopic rod of the first telescopic cylinder drives the jig to move backward. Through the irradiation of the lamp and the reflection of the light-transmitting plate, the detection plate can detect the light-transmitting condition of the touch screen, so as to evaluate the light-transmitting performance of the touch screen.

[0014] 2. The present invention is provided with components such as a rack, a gear, and a reciprocating lead screw. When the jig passes directly below the lamp, the rack on the placement frame meshes with the gear, which causes the gear to rotate. The rotation of the gear drives the second sliding rod to rotate through the synchronous belt component. The rotation of the second sliding rod causes the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw causes the moving block to move left and right. While the moving block moves, it drives the lamp to move left and right. When the lamp moves left and right, due to the cooperation of the cam and the inclined plate, the lamp rotates around the rotating sleeve, so that the lamp can irradiate 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-transmitting detection of the touch screen.

Detailed implementation manners

[0027] The present invention will be further described below in conjunction with specific embodiments. It should also be noted that unless otherwise clearly defined and limited, terms such as "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] A touch screen quality detection platform, as Figures 1-11As shown in the figure, it includes a base 101. An installation frame 102 is fixedly connected to the top surface of the base 101. A jig for placing a touch screen is arranged on the top surface of the base 101. The jig is driven by a first telescopic cylinder 201 to achieve sliding. An artificial finger simulation component for performing touch detection on the touch screen is arranged inside the installation frame 102. The artificial finger simulation component includes a first touch head 301 and a second touch head 302. The first touch head 301 is arranged in the middle of the installation frame 102. There are two second touch heads 302, and they are symmetrically arranged with the first touch head 301 as the center. Both the first touch head 301 and the second touch head 302 are pressed downward through a first driving component. The second touch head 302 approaches or moves away from the first touch head 301 through a second driving component. A light transmission detection component is arranged inside the installation frame 102, and the light transmission detection component is located in front of the artificial finger simulation component. The light transmission detection component includes lamps 401 uniformly 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. A detection plate 402 is installed inside the base 101 directly below the lamps 401.

[0029] It can be seen from this that first, the distance between the second touch head 302 and the first touch head 301 is adjusted through the second driving component. Then, the touch screen to be detected 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 backward. Since the light transmission detection component is located in front of the artificial finger simulation component, the light transmission of the touch screen is detected first. Through the irradiation of the lamps 401 and the reflection of the light transmission plate 103, the detection plate 402 can detect the light transmission situation of the touch screen, so as to evaluate the light transmission performance of the touch screen. Then, the first driving component is started. The first driving component makes the first touch head 301 or the second touch head 302 press downward. Then, the first touch head 301 or the second touch head 302 performs simulated touch scribing on the surface of the touch screen, simulating the touch scribing of a human finger for detection. In this way, through the simulated touch scribing operation and the light transmission performance detection, it is possible to judge whether the touch response and light transmission performance of the touch screen meet the quality standards, and then obtain the quality detection result of the touch screen.

[0030] Furthermore, a first mounting frame 303 is fixedly connected to the middle inside the mounting frame 102. The first touch head 301 is sleeved on the first mounting frame 303 in a vertically sliding manner. The second driving component includes limiting plates 304 symmetrically arranged on the left and right sides inside the mounting frame 102. The two limiting plates 304 are moved away from or close to each other through a first linear module 306. The first linear module 306 is specifically a driving motor and a bidirectional lead screw. That is, a bidirectional lead screw is rotatably connected inside the mounting frame 102. The bidirectional lead screw is driven by the driving motor to rotate. The bidirectional lead screw is threadedly connected to the two limiting plates 304. A fixed frame 307 is fixedly connected to the side surface of the limiting plate 304 close to each other. A second mounting frame 308 is slidably connected inside the fixed frame 307. The second touch head 302 is sleeved on the second mounting frame 308 in a vertically sliding manner. The second mounting frame 308 is driven by an electric push rod 309 to slide; The first driving component includes a second telescopic cylinder 311 installed inside the mounting frame 102. An extrusion plate 312 is fixedly connected to the telescopic rod of the second telescopic cylinder 311. A fourth elastic member 313 is arranged 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. Rotating balls 314 are rotatably connected to the tops of the first touch head 301 and the second touch head 302. A reset groove 3121 and an extrusion protrusion 3122 that cooperate with the rotating balls 314 are arranged on the extrusion plate 312. Through the protrusions on the reset groove 3121 and the extrusion protrusion 3122, the first touch head 301 can be individually pressed downward, or the two second touch heads 302 can be pressed downward, or the first touch head 301 and the second touch heads 302 can be pressed downward simultaneously; It can be seen that the first linear module 306 is used to move the limiting plates 304 away from or close to each other, so as to adapt to jigs of different sizes. At the same time, the distance between the second touch head 302 and the first touch head 301 can be adjusted, so as to adapt to touch screens of different sizes. Then, the second telescopic cylinder 311 is started. The telescopic rod of the second telescopic cylinder 311 drives the extrusion plate 312 to move towards the first touch head 301 and the second touch head 302, as 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 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.

[0031] 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 limiting 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.

[0032] It can be seen from this that in order to prevent the light 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 slot 3041, that is, the limiting plate 304 presses the second clamping rod 207, so that the two second clamping rods 207 move away from each other, and then the support plate 205 is folded into the second sliding slot 2021. At the same time, the limiting plate 304 will press the first clamping rod 210, so that the two first clamping rods 210 move closer to each other, and then the clamping plates 208 move closer to each other, and then the clamping plates 208 clamp the touch screen from the side, thus preventing the support plate 205 from affecting the light transmittance detection. The second elastic member 206 and the first elastic member 209 can help the support plate 205 and the clamping plates 208 to reset.

[0033] Furthermore, a limiting slot 2023 is provided on one side of the placement frame 202. A limiting rod 211 is rotatably connected to the limiting slot 2023. A third clamping rod 212 is slidably connected to the side wall of the limiting slot 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. A clamping hole matching with the third clamping rod 212 is provided on the limiting rod 211.

[0034] It can be seen from this that in order to prevent the cable on the touch screen from interfering with the detection, after the touch screen is placed on the top of the support plate 205, the cable on the touch screen is placed into the limiting slot 2023, and the cable is connected to the outside. At the same time, the limiting rod 211 is rotated so that the third clamping rod 212 is inserted into the clamping hole, so that the limiting rod 211 can limit the cable on the touch screen and prevent the cable on the touch screen from interfering with the detection.

[0035] Furthermore, a first sliding rod 403 is provided on the inner side wall of the installation frame 102. The first sliding rod 403 moves up and down through a second linear module 404. The second linear module 404 specifically includes a driving motor and a screw rod, which is a prior art. A sliding sleeve 405 is slidably connected to the first sliding rod 403. An installation sleeve 406 is rotatably connected to the sliding sleeve 405. The lamp 401 is fixed on the installation sleeve 406 through a fixing screw rod 407. Fixed blocks 411 are symmetrically and fixedly connected to the inner side wall of the installation frame 102. A fixing plate 412 and a second sliding rod 413 are provided on one side surface of the two fixed blocks 411 close to each other. The second sliding rod 413 is rotatably connected to the fixed block 411. The fixing plate 412 is slidably connected to the fixed block 411. A reciprocating lead screw 414 is uniformly and fixedly connected to the second sliding rod 413. A moving block 415 is slidably connected to the fixing plate 412. The moving block 415 is threadedly connected to the reciprocating lead screw 414. A rotating sleeve 416 is rotatably connected to the moving block 415. A torsion spring is provided between the rotating sleeve 416 and the moving block 415. One end of the lamp 401 is sleeved in the rotating sleeve 416. A cam 417 is fixedly connected to the rotating shaft of the rotating sleeve 416. Diagonal plates 418 that cooperate with the cam 417 are symmetrically and fixedly connected to the fixing plate 412 with the lamp 401 as the center through connecting rods. Rack bars 421 are fixedly connected to the left and right sides of the top surface of the placement frame 202. Gears 422 that cooperate with the rack bars 421 are rotatably connected to one side surface of the limiting plate 304 close to each other. The gears 422 are connected to the second sliding rod 413 through a synchronous belt component 423. It should be noted that the synchronous wheels in the synchronous belt component 423 are connected to the second sliding rod 413 through a key and keyway connection relationship.

[0036] It can be seen from this that by starting the second linear module 404, the height between the lamp 401 and the touch screen can be changed, so as to adapt to touch screens of different sizes. When the jig passes directly below the lamp 401, the rack bars 421 on the placement frame 202 mesh with the gears 422, thereby causing the gears 422 to rotate. The rotation of the gears 422 drives the second sliding rod 413 to rotate through the synchronous belt component 423. The rotation of the second sliding rod 413 causes the reciprocating lead screw 414 to rotate. The rotation of the reciprocating lead screw 414 causes the moving block 415 to move left and right. While the moving block 415 moves, it drives the lamp 401 to move left and right. While the lamp 401 moves left and right, due to the cooperation between the cam 417 and the diagonal plate 418, the lamp 401 rotates with the rotating sleeve 416 as the center. In this way, the lamp 401 can irradiate 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.

[0037] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings.
