Description

Technical Field

[0001] The present invention relates to the technical field of screen testing, and in particular to a device for testing the pressure resistance of a touch screen. Background Art

[0002] A touch screen, also known as a touchscreen or touch panel, is an inductive liquid crystal display device that accepts input signals such as contacts. When a user touches the screen, the on-screen feedback system is activated according to pre-programmed signals. It is currently widely used in mobile phones, tablet computers, retail, and public information search, among other fields. Touch screens require certain characteristics, including transparency, reflectivity, positioning capabilities, and durability. Durability plays a decisive role in the lifespan of the screen. Pressure testing of touch screens can test the durability of the screen. Existing touch screen pressure resistance testing devices typically require manual positioning and employ a single testing method, failing to meet the actual needs of touch screen testing and also failing to perform automated, multi-mode testing. Summary of the Invention

[0004] Furthermore, the main device includes a motor arranged next to the frame, an output toothless gear is fixedly installed on the motor shaft of the motor, an internal toothless gear is rotatably installed on the frame, an external gear is fixedly installed on the internal toothless gear, and the external gear is engaged with the output toothless gear.

[0005] Furthermore, two fixed support rods are fixedly installed on the frame, and two lifting support rods are slidably installed on the frame. The two fixed support rods and the lifting support rod are respectively arranged diagonally. Both the fixed support rods and the lifting support rods are provided with support blocks for supporting the touch screen. When in use, the touch screen is placed on the support blocks.

[0006] Furthermore, a camshaft is rotatably mounted on the bottom of the frame, two cams and an internal gear are fixedly mounted on the camshaft, a lifting frame is fixedly mounted below the two lifting support rods, the lifting frame cooperates with the cam, and the internal gear is engaged with the internal toothless gear.

[0007] When the lifting support rod is not raised, the touch screen is supported by the two fixed support rods. The touch screen is supported at two diagonal points. The rotation of the motor drives the output toothless gear to rotate. The rotation of the output toothless gear drives the outer gear to rotate intermittently, thereby driving the inner toothless gear to rotate intermittently. The inner toothless gear drives the inner gear to rotate intermittently, thereby driving the camshaft and the cam to rotate. The rotation of the cam drives the lifting frame to rise, thereby driving the lifting support rod to rise. At this time, the support blocks of the lifting support rod and the fixed support rod are at the same height. The touch screen is supported by the two lifting support rods and the two fixed support rods at the same time. At this time, the touch screen is supported by four points on the outside.

[0008] The output tooth-missing gear rotates the outer gear and the inner tooth-missing gear half a circle each time, and the inner tooth-missing gear drives the inner gear to rotate half a circle each time.

[0009] Furthermore, the pressure device includes a lower pressure frame slidably mounted on the side spring frame, three return springs are provided between the lower pressure frame and the side spring frame, an eccentric rotating rod is rotatably mounted on the lower pressure frame, and the eccentric rotating rod is eccentrically rotatably mounted with the external gear.

[0012] The rotation of the outer gear drives the eccentric rotating rod to rotate, thereby driving the lower pressure frame to descend. The output toothless gear drives the outer gear to rotate half a circle each time. When the pop-up head contacts the touch screen, the lower pressure frame continues to descend, causing the pop-up spring to be compressed, and the lower pressure frame and the pressure block to slide relative to each other to perform a pressure test on the touch screen. When the outer gear is disengaged from the output toothless gear, the reset spring rebounds, driving the outer gear and the inner toothless gear to continue rotating, so that the lower pressure frame and the pop-up head are reset.

[0014] Furthermore, an internal threaded frame is slidably installed on the lower sliding rod, and an internal thread is provided on the internal threaded frame. The internal threaded frame and the bidirectional screw rod form a threaded match. Two blocking frames are fixedly installed on the internal threaded frame, and the slip ring is rotatably installed with the internal threaded frame. A lifting frame is fixedly installed under the center support plate, and a transverse groove is provided on the lifting frame. A docking gear is rotatably installed on the frame body, and a sliding column is eccentrically provided on the docking gear, and the sliding column slides in the transverse groove of the lifting frame.

[0015] The rotation of the outer gear drives the upper transmission gear to rotate, thereby driving the intermediate gear and the lower gear to rotate. The rotation of the intermediate gear drives the sliding shaft, the sliding toothed gear and the slip ring to rotate. The lower gear drives the two-way screw to rotate, thereby driving the internal threaded frame to slide along the lower slide rod. The internal threaded frame drives the slip ring and the sliding toothed gear to slide along the sliding shaft, realizing that the sliding toothed gear rotates while sliding toward the intermediate gear. The internal threaded frame advances one-third of the stroke each time. When the internal threaded frame advances two-thirds of the stroke, the blocking frame reaches under the pressure block. When the internal threaded frame advances three times, the sliding toothed gear meshes with the docking gear, and the sliding toothed gear drives the docking gear and the sliding column to rotate, thereby driving the lifting frame and the center support plate to rise. The center support plate supports the touch screen, so that the center support plate supports the bottom center of the touch screen, and at this time the blocking frame leaves the bottom of the pressure block, and the pressure block pops out to perform impact and pressure test on the touch screen.

[0016] Compared with the prior art, the present invention has the following advantages: (1) the main device provided by the present invention can switch the corner support mode of the touch screen, namely the diagonal two-point support mode and the edge four-point support mode, and can also provide center support for the display screen through the internal support device, so that the touch screen can be subjected to three different forms of pressure resistance tests; (2) after the internal thread frame provided by the present invention moves twice, the blocking frame reaches the bottom of the pressure block, and after the internal thread frame moves three times, the pressure block pops out after accumulating force, and the touch screen can be subjected to the impact pressure resistance test of the middle support; (3) when the output toothless gear provided by the present invention rotates the first circle, the touch screen is subjected to the pressure resistance test of the diagonal two-point support through the pop-up head, and when it rotates the second circle, the touch screen is subjected to the pressure resistance test of the diagonal four-point support through the pop-up head, the blocking frame reaches the bottom of the pressure block, and when it rotates the third circle, the center support plate supports the bottom center of the touch screen, the blocking frame leaves the bottom of the pressure block, and the pressure block and the pop-up head pop out to perform the impact pressure resistance test of the center support of the touch screen, with a high degree of automation.

The fixed support rods 105 and the lifting support rods 106 are both provided with support blocks for supporting the touch screen 4. When in use, the touch screen 4 is placed on the support blocks.

[0031] like Figure 2-Figure 4 As shown, a camshaft 108 is rotatably installed at the bottom of the frame 101, and two cams 109 and an internal gear 107 are fixedly installed on the camshaft 108. A lifting frame 110 is fixedly installed under the two lifting support rods 106. The lifting frame 110 cooperates with the cam 109, and the internal gear 107 engages with the internal toothless gear 104.

[0032] When the lifting support rod 106 is not raised, the touch screen 4 is supported by the two fixed support rods 105. The touch screen 4 is supported at two diagonal points. The rotation of the motor 102 drives the output toothless gear 111 to rotate.

[0037] The rotation of the outer gear 103 drives the eccentric rotating rod 209 to rotate, thereby driving the lower pressure frame 203 to descend, the return spring 202 is compressed, and the output toothless gear 111 drives the outer gear 103 to rotate half a circle each time. When the pop-up head 208 contacts the touch screen 4, the lower pressure frame 203 continues to descend, causing the pop-up spring 207 to be compressed, and the lower pressure frame 203 and the pressure block 206 to slide relative to each other, performing a pressure test on the touch screen 4. When the outer gear 103 is disengaged from the output toothless gear 111, the return spring 202 rebounds, driving the outer gear 103 and the inner toothless gear 104 to continue to rotate half a circle, so that the lower pressure frame 203 and the pop-up head 208 are reset.

[0039] like Figure 7-Figure 9As shown, an internal thread frame 310 is slidably installed on the lower slide rod 306, and an internal thread is provided on the internal thread frame 310. The internal thread frame 310 forms a threaded fit with the bidirectional screw rod 307. Two blocking frames 311 are fixedly installed on the internal thread frame 310, and the slip ring 309 is rotatably installed with the internal thread frame 310. A lifting frame 312 is fixedly installed below the center support plate 301, and a horizontal groove is provided on the lifting frame 312.

The sliding column 314 slides in the horizontal groove of the lifting frame 312.

[0040] The rotation of the outer gear 103 drives the upper transmission gear 302 to rotate, thereby driving the intermediate gear 303 and the lower gear 304 to rotate. The rotation of the intermediate gear 303 drives the sliding shaft 305, the sliding toothless gear 308 and the slip ring 309 to rotate. The lower gear 304 drives the bidirectional screw rod 307 to rotate, thereby driving the internal threaded frame 310 to slide along the lower slide rod 306. The internal threaded frame 310 drives the slip ring 309 and the sliding toothless gear 308 to slide along the sliding shaft 305, so that the sliding toothless gear 308 rotates and slides toward the intermediate gear 303. The internal threaded frame 310 advances one-third of the stroke each time. , when the internal thread frame 310 advances two-thirds of the stroke, the blocking frame 311 arrives under the pressure block 206. When the internal thread frame 310 advances three times, the sliding toothless gear 308 engages with the docking gear 313, and the sliding toothless gear 308 drives the docking gear 313 and the sliding column 314 to rotate, thereby driving the lifting frame 312 and the center support plate 301 to rise.

At this time, the blocking frame 311 leaves the bottom of the pressure block 206, and the pressure block 206 pops out to perform an impact and pressure test on the touch screen.

[0041] When the output toothless gear 111 rotates the first circle, it first drives the outer gear 103 and the inner toothless gear 104 to rotate half a circle. In the first half circle, the inner toothless gear 104 will not drive the inner gear 107 to rotate. At this time, the pop-up head 208 is used to test the compressive strength of the touch screen 4 at two diagonal points of support. At this time, the internal threaded frame 310 moves one-third of the stroke. After the second half circle, that is, the test is completed, under the action of the return spring 202 rebounding, the inner toothless gear 104 drives the inner gear 107 to rotate half a circle, so that the next test is switched to diagonal four-point support; when the output toothless gear 111 rotates the second circle, it drives the outer gear 103 and the inner toothless gear 104 to rotate half a circle. At this time, The touch screen 4 is tested for its compressive strength at four diagonal points by the pop-up head 208. At this time, the internal threaded frame 310 moves to two-thirds of its stroke, and the blocking frame 311 reaches under the pressure block 206. When the output toothless gear 111 rotates the third circle, it drives the external gear 103 and the internal toothless gear 104 to rotate half a circle. At this time, the docking gear 313 engages with the sliding toothless gear 308, driving the center support plate 301 to rise completely. The center support plate 301 supports the bottom center of the touch screen 4. At the same time, the blocking frame 311 leaves the bottom of the pressure block 206, and the pressure block 206 and the pop-up head 208 pop out to test the impact and compressive strength of the center support of the touch screen 4.

[0042] The operating principle of a touch screen pressure resistance testing device disclosed in the present invention is as follows: When the lifting support rod 106 is not raised, the touch screen 4 is supported by two fixed support rods 105, with the touch screen 4 supported at two diagonally opposite points. The motor 102 rotates, driving the output toothless gear 111 to rotate. The output toothless gear 111 rotates, which drives the outer gear 103 to rotate intermittently, thereby driving the inner toothless gear 104 to rotate intermittently. The inner toothless gear 104 drives the inner gear 107 to rotate intermittently, thereby driving the camshaft 108 and cam 109 to rotate. The rotation of the cam 109 drives the lifting frame 110 to rise, thereby driving the lifting support rod 106 to rise. At this time, the support blocks of the lifting support rod 106 and the fixed support rod 105 are at the same height. The touch screen 4 is supported simultaneously by the two lifting support rods 106 and the two fixed support rods 105, and the touch screen 4 is now supported at four points on the outside. Each time the output toothless gear 111 rotates the outer gear 103 and the inner toothless gear 104, the inner toothless gear 104 drives the inner gear 107 to rotate half a circle. The rotation of the outer gear 103 drives the eccentric rotating rod 209 to rotate, thereby driving the lower pressure frame 203 to descend, the return spring 202 is compressed, and the output toothless gear 111 drives the outer gear 103 to rotate half a circle each time. When the pop-up head 208 contacts the touch screen 4, the lower pressure frame 203 continues to descend, causing the pop-up spring 207 to be compressed, and the lower pressure frame 203 and the pressure block 206 to slide relative to each other, performing a pressure test on the touch screen 4. When the outer gear 103 is disengaged from the output toothless gear 111, the return spring 202 rebounds, driving the outer gear 103 and the inner toothless gear 104 to continue to rotate half a circle, so that the lower pressure frame 203 and the pop-up head 208 are reset. The rotation of the outer gear 103 drives the upper transmission gear 302 to rotate, thereby driving the intermediate gear 303 and the lower gear 304 to rotate. The rotation of the intermediate gear 303 drives the sliding shaft 305, the sliding toothless gear 308 and the slip ring 309 to rotate. The lower gear 304 drives the bidirectional screw rod 307 to rotate, thereby driving the internal threaded frame 310 to slide along the lower slide rod 306. The internal threaded frame 310 drives the slip ring 309 and the sliding toothless gear 308 to slide along the sliding shaft 305, so that the sliding toothless gear 308 rotates and slides toward the intermediate gear 303. The internal threaded frame 310 advances one-third of the stroke each time. , when the internal thread frame 310 advances two-thirds of the stroke, the blocking frame 311 arrives under the pressure block 206. When the internal thread frame 310 advances three times, the sliding toothless gear 308 engages with the docking gear 313, and the sliding toothless gear 308 drives the docking gear 313 and the sliding column 314 to rotate, thereby driving the lifting frame 312 and the center support plate 301 to rise. The center support plate 301 supports the touch screen 4, so that the center support plate 301 supports the bottom center of the touch screen 4. At this time, the blocking frame 311 leaves the bottom of the pressure block 206, and the pressure block 206 pops out to perform an impact and pressure test on the touch screen.

[0043] When the output toothless gear 111 rotates the first circle, it first drives the outer gear 103 and the inner toothless gear 104 to rotate half a circle. In the first half circle, the inner toothless gear 104 will not drive the inner gear 107 to rotate. At this time, the pop-up head 208 is used to test the compressive strength of the touch screen 4 at two diagonal points of support. At this time, the internal threaded frame 310 moves one-third of the stroke. After the second half circle, that is, the test is completed, under the action of the return spring 202 rebounding, the inner toothless gear 104 drives the inner gear 107 to rotate half a circle, so that the next test is switched to diagonal four-point support; when the output toothless gear 111 rotates the second circle, it drives the outer gear 103 and the inner toothless gear 104 to rotate half a circle. At this time, The touch screen 4 is tested for its compressive strength at four diagonal points by the pop-up head 208. At this time, the internal threaded frame 310 moves to two-thirds of its stroke, and the blocking frame 311 reaches under the pressure block 206. When the output toothless gear 111 rotates the third circle, it drives the external gear 103 and the internal toothless gear 104 to rotate half a circle. At this time, the docking gear 313 engages with the sliding toothless gear 308, driving the center support plate 301 to rise completely. The center support plate 301 supports the bottom center of the touch screen 4. At the same time, the blocking frame 311 leaves the bottom of the pressure block 206, and the pressure block 206 and the pop-up head 208 pop out to test the impact and compressive strength of the center support of the touch screen 4.

A touch screen pressure resistance testing device according to claim 3, characterized in that: The inner support device comprises an upper transmission gear (302) rotatably mounted on the frame (101), the upper transmission gear (302) meshing with the outer gear (103), a sliding shaft (305) and a bidirectional screw rod (307) rotatably mounted on the frame (101), an intermediate gear (303) fixedly mounted on the sliding shaft (305), a sliding toothless gear (308) slidably mounted on the sliding shaft (305), a slip ring (309) fixedly mounted on the sliding toothless gear (308), a lower gear (304) fixedly mounted on the bidirectional screw rod (307), the intermediate gear (303) meshing with the upper transmission gear (302), the intermediate gear (303) meshing with the lower gear (304), and a lower sliding rod (306) fixedly mounted on the frame (101); An internal thread frame (310) is slidably mounted on the lower slide rod (306), and an internal thread is provided on the internal thread frame (310). The internal thread frame (310) and the bidirectional screw rod (307) form a threaded fit, and two blocking frames (311) are fixedly mounted on the internal thread frame (310). The slip ring (309) is rotatably mounted on the internal thread frame (310). A lifting frame (312) is fixedly mounted below the center support plate (301), and a transverse groove is provided on the lifting frame (312). A docking gear (313) is rotatably mounted on the frame body (101), and a sliding column (314) is eccentrically provided on the docking gear (313). The sliding column (314) slides in the transverse groove of the lifting frame (312). When the output toothless gear (111) rotates for the third time, it drives the outer gear (103) and the inner toothless gear (104) to rotate half a circle. At this time, the docking gear (313) is engaged with the sliding toothless gear (308), driving the central support plate (301) to fully rise. The central support plate (301) supports the bottom center of the touch screen (4). At the same time, the blocking frame (311) leaves the bottom of the pressure block (206), and the pressure block (206) and the pop-up head (208) pop out, and the impact pressure resistance of the center support of the touch screen (4) is tested.
