Description

Technical Field

[0001] The present invention relates to the technical field of electronic product detection, and particularly relates to a circuit docking device for touch screen testing. Background Art

[0002] With the development of technology and the improvement of people's living standards, electronic products are more and more widely used. Mobile phones, computers and tablets are the most widely used electronic products. Most of the existing electronic products use touch screens. During the processing of touch screens, they are mostly detected. The detection is usually to connect the wiring block of the touch screen to the wiring seat connected to the power supply first, and then draw lines on the screen through a screen swiping device, and determine whether the touch screen is intact by detecting the integrity of the lines displayed on the display screen.

[0003] The existing circuit docking devices for testing have the following deficiencies:

[0004] 1. It is impossible to simultaneously position multiple surfaces of the wiring block. If the wiring block is accidentally touched during the test, it will cause the plug on the wiring seat to loosen or even detach, or the wire on the wiring block to loosen from the connection end of the touch screen, which will affect the test work and reduce the test effect.

[0005] 2. The existing devices generally include multiple mechanisms, and each mechanism usually requires a separate drive source, such as a cylinder, a motor, and an electric push rod, etc. This results in a large overall power consumption of the device, increases the use cost, and thus increases the test cost.

[0006] 3. Generally, manual docking of the wiring block interface and the wiring seat plug is carried out. By visual observation, misinsertion is likely to occur, thus affecting the docking efficiency. Summary of the Invention

[0028] 4. The present invention designs two telescopic springs and four reset springs, in conjunction with the screw rod pushing structure, which can ensure that the four pressure rods rotate downward slowly and tightly press the top of the connection block, preventing damage to the connection block caused by excessive downward pressure or too fast downward speed, playing a role in protecting the test equipment, avoiding losses, and at the same time facilitating the improvement of the test quality.

[0029] 5. The present invention designs an anti-slip pad at the end of each pressure rod, which can increase the friction generated when the pressure rod acts on the top of the connection block, prevent slipping, and facilitate the improvement of the downward pressure effect.

The two overlapping plates 16 are symmetrically arranged on the top of the detection table 12. Each overlapping plate 16 is of an L-shaped structure. The wiring block 14 is inserted between the tops of the two overlapping plates 16, and each sliding component is arranged on one overlapping plate 16;

[0047] The anti - detachment mechanism is arranged at the top of the detection table 12. The anti - detachment mechanism includes a transmission component, a lifting component, a conversion component and four pressure rods 17. Four support plates are symmetrically arranged at the top of the detection table 12. A rotating shaft 18 is arranged between every two support plates on the same side. Both ends of each rotating shaft 18 are fixedly provided with two pressure rods 17. The conversion component is arranged between the two rotating shafts 18. The lifting component is arranged between the transmission component and two of the pressure rods 17. The transmission component is arranged between the lifting component and one of the sliding components to drive the four pressure rods 17 to rotate downward and press the connection block 14 tightly when the connection block 14 approaches the connection seat 13 synchronously.

[0048] Refer to Figures 1 to 8 As shown, the manual component includes a handwheel 19, a lead screw 20, a U - shaped plate 21 and two guide rods 22. The U - shaped plate 21 is fixedly arranged at the top of the detection table 12. Both guide rods 22 are fixedly arranged on the outer wall of the U - shaped plate 21. The lead screw 20 is rotatably arranged on the top of the U - shaped plate 21. The handwheel 19 is fixedly arranged at one end of the lead screw 20. When performing a touch - screen test, first place the connection block 14 horizontally between the tops of the two overlapping plates 16, and keep the outer wall of the end of the connection block 14 away from the push plate 15 in contact with both second sliders 26. Then, manually rotate the handwheel 19. Since the handwheel 19 is fixedly connected to the lead screw 20, the lead screw 20 is rotatably connected to the U - shaped plate 21, and the U - shaped plate 21 is fixedly connected to the detection table 12, the lead screw 20 rotates on the top of the U - shaped plate 21.

[0049] Refer to Figures 1 to 8 As shown, the moving component includes a first slider 23, a connecting plate 24 and two push rods 25. The first slider 23 is slidably arranged on the outer walls of the two guide rods 22, and the first slider 23 is threadedly connected to the lead screw 20. The connecting plate 24 is fixedly arranged on the top of the first slider 23. Both push rods 25 are fixedly arranged on the outer wall of one end of the connecting plate 24. The other ends of both push rods 25 are fixedly connected to the push plate 15. When the lead screw 20 rotates on the top of the U - shaped plate 21, since the first slider 23 is threadedly connected to the lead screw 20, the first slider 23 is also slidably connected to the outer walls of the two guide rods 22, the connecting plate 24 is fixedly connected to the first slider 23, both push rods 25 are fixedly connected to the connecting plate 24, and the other ends of both push rods 25 are fixedly connected to the push plate 15, the push plate 15 is driven to move towards the end close to the connection block 14 until the push plate 15 contacts the end of the connection block 14 away from the second slider 26. Then, rotate the handwheel 19 to continue driving the push plate 15 to push the connection block 14 towards the end close to the connection seat 13, so as to facilitate the interface 46 on the connection block 14 to approach the plug 45 on the connection seat 13.

[0050] Refer to Figures 1 to 8As shown, each sliding component includes a second slider 26, a telescopic spring 27 and a limiting rod 28. A chute is provided on the inner wall of each overlapping plate 16. Each second slider 26 is slidably arranged inside a chute. The limiting rod 28 is fixedly arranged on the outer wall of one end of the second slider 26. The telescopic spring 27 is sleeved on the outer wall of the limiting rod 28. The outer wall of the second slider 26 and the inner wall of the chute are respectively in contact with both ends of the telescopic spring 27. And the end of the limiting rod 28 away from the second slider 26 passes through the chute and extends to the outside of the overlapping plate 16. When the push plate 15 pushes the wiring block 14 towards the end close to the wiring seat 13, that is, while the interface 46 on the wiring block 14 approaches the plug 45 on the wiring seat 13, since the outer wall of the end of the wiring block 14 away from the push plate 15 is in close contact with the second slider 26, the second slider 26 slides towards the end close to the wiring seat 13 inside the chute. Since one end of the limiting rod 28 is fixedly connected to the second slider 26, the other end of the limiting rod 28 passes through the chute and extends to the outside of the overlapping plate 16, and the telescopic spring 27 is sleeved on the limiting rod 28, the limiting rod 28 slides towards the end close to the wiring seat 13 inside the chute and causes the telescopic spring 27 to change from the initial state to the tense state. And after the touch screen test is over, the wire 47 can be directly unplugged from the touch screen of the wiring block 14, and then the next touch screen test can be carried out. When the wiring block 14 fails or needs to be removed for replacement, by manually rotating the handwheel 19 in the reverse direction, the push plate 15 is reset. Then, by grasping the wiring block 14 by hand, its interface 46 is unplugged from the plug 45 on the wiring seat 13, so that the second slider 26 slides towards the end away from the wiring seat 13 inside the two chutes, so that the telescopic spring 27 gradually changes from the tense state to the initial state. Thus, the synchronous belt 40 drives the four pressing rods 17 to rotate upwards, that is, rotate towards the end away from the wiring block 14, release the wiring block 14, and remove it from the tops of the two wiring boards.

[0051] Referring to Figures 1 to 8 As shown, the transmission component includes a push block 29, an L-shaped plate 30 and a pull rod 31. The push block 29 is fixedly arranged at one end of the limiting rod 28 away from the second slider 26. The L-shaped plate 30 is fixedly arranged on the outer wall of the push block 29. The pull rod 31 is fixedly arranged at the end of the L-shaped plate 30 away from the push block 29. While the limiting rod 28 slides towards the end close to the wiring seat 13 inside the chute, since the push block 29 is fixedly connected to one end of the limiting rod 28 away from the second slider 26, the L-shaped plate 30 is fixedly connected to the outer wall of the push block 29, and the pull rod 31 is fixedly connected to the end of the L-shaped plate 30 away from the push block 29, the pull rod 31 moves towards the end away from the detection table 12.

[0052] Referring to Figures 1 to 8As shown in the figure, the jacking assembly includes a first jacking block 32, a second jacking block 33, a jacking rod 34, an insertion rod 35 and a lifting frame 36. The first jacking block 32 is slidably arranged on the top of the inspection table 12 through a sliding column 37. The second jacking block 33 is slidably arranged on the top of the first jacking block 32. The first jacking block 32 and the second jacking block 33 are in contact with each other, and both the first jacking block 32 and the second jacking block 33 are wedge-shaped structures. The jacking rod 34 is fixedly arranged on the top of the second jacking block 33. The lifting frame 36 is slidably arranged on the top of the inspection table 12 through four guide rods. The bottom of the lifting frame 36 is fixedly connected to the top of the jacking rod 34. The insertion rod 35 is fixedly arranged on the top of the lifting frame 36. Avoidance grooves 38 are respectively arranged on the outer walls of two pressure rods 17 close to the lifting frame 36. The insertion rod 35 is inserted into the two avoidance grooves 38. When the pull rod 31 moves towards the end far away from the inspection table 12, since the end of the pull rod 31 far away from the L-shaped plate 30 is fixedly connected to the first jacking block 32, and the first jacking block 32 is slidably connected to the inspection table 12 through the sliding column 37, the first jacking block 32 slides towards the end close to the wiring seat 13 on the top of the inspection table 12. Since the second jacking block 33 is slidably connected to the first jacking block 32, the second jacking block 33 is in contact with the first jacking block 32, and both the first jacking block 32 and the second jacking block 33 are wedge-shaped structures. The second jacking block 33 is fixedly connected to the bottom of the lifting frame 36 through the jacking rod 34, the insertion rod 35 is fixedly connected to the top of the lifting frame 36. Avoidance grooves 38 are respectively arranged on the outer walls of two pressure rods 17 close to the lifting frame 36. The insertion rod 35 is inserted into the two avoidance grooves 38. Two pressure rods 17 close to the lifting frame 36 are respectively rotatably connected to two support plates through a rotating shaft 18. Then, when the insertion rod 35 jacks up and slides in the two avoidance grooves 38, the two pressure rods 17 close to the lifting frame 36 are driven to rotate around the rotating shaft 18 towards the end close to the top of the wiring block 14, that is, rotate downward. When the interface 46 on the wiring block 14 is successfully docked with the plug 45 on the wiring seat 13, the two pressure rods 17 close to the lifting frame 36 rotate downward synchronously to press one end of the top of the wiring block 14, realizing the limit of one end of its top.

[0053] Referring to Figures 1 to 8 As shown in the figure, an anti-drop block is fixedly arranged at the top end of each guide rod, and a return spring 39 is sleeved on the outer wall of each guide rod. The top of the lifting frame 36 and the bottom of each anti-drop block are respectively in contact with two ends of a return spring 39. When the lifting rod rises, since the top of the lifting frame 36 and the bottom of each anti-drop block are respectively in contact with two ends of a return spring 39, the return spring 39 will change from the initial state to the tightened state. When the lifting frame 36 resets, the return spring 39 is no longer in contact and returns to the initial state again.

[0054] Referring to Figures 1 to 8As shown in the figure, the conversion component includes a synchronous belt 40, a first gear 41, a second gear 42 and two synchronous pulleys 43. A hinge shaft is rotatably provided at the top of one support plate. The two synchronous pulleys 43 are respectively arranged on the hinge shaft and one of the rotating shafts 18 close to the lifting frame 36. The synchronous belt 40 is sleeved between the two synchronous pulleys 43. The first gear 41 and the second gear 42 are respectively fixedly arranged on the hinge shaft and the other rotating shaft 18. The first gear 41 and the second gear 42 are meshed and connected. When two of the pressure rods 17 close to the lifting frame 36 rotate around the rotating shaft 18 towards one end close to the top of the connection block 14, since the two synchronous pulleys 43 are respectively fixedly connected to the hinge shaft and one of the rotating shafts 18 close to the lifting frame 36, the two synchronous pulleys 43 are sleeved through the synchronous belt 40, the first gear 41 and the second gear 42 are respectively fixedly connected to the hinge shaft and the other rotating shaft 18, and the first gear 41 and the second gear 42 are meshed and connected. Therefore, the other two pressure rods 17 synchronously rotate around the other rotating shaft 18 towards the other end close to the top of the connection block 14, that is, rotate downward. When the interface 46 on the connection block 14 is successfully docked with the plug 45 on the connection base 13, the other two pressure rods 17 rotate downward synchronously to tightly press the other end of the top of the connection block 14, realizing the limit of the other end of its top. Furthermore, the complete limit of the top of the connection block 14 is realized through the four pressure rods 17.

[0055] Referring to Figures 1 to 8 As shown in the figure, an anti-slip pad 44 is attached to each end of the pressure rod 17 away from the rotating shaft 18. The anti-slip pad 44 can increase the friction generated when the pressure rod 17 applies to the top of the connection block 14, prevent slipping, and is beneficial to improving the downward pressing effect. Preferably, the anti-slip pad 44 is a rubber anti-slip pad 44 or a silicone anti-slip pad 44.

[0056] Referring to Figures 1 to 8 As shown in the figure, a plug 45 is provided on the outer wall of the connection base 13. An interface 46 and a wire 47 are respectively provided on the outer walls of both ends of the connection block 14. The wire 47 facilitates the electrical connection between the connection block 14 and the touch screen to be tested. The plug 45 is connected to the power supply through the connection base 13. After the plug 45 is inserted into the interface 46, the touch screen can be powered on through the connection block 14, thus facilitating the test of the touch screen.

[0057] Working principle of the present invention: The wire 47 facilitates the electrical connection between the wiring block 14 and the touch screen to be tested. The plug 45 is connected to the power supply through the wiring seat 13. After the plug 45 is inserted into the interface 46, the touch screen can be powered on through the wiring block 14, thus facilitating the test thereof. When testing the touch screen, first place the wiring block 14 horizontally between the tops of the two overlapping plates 16, and keep the outer wall of the end of the wiring block 14 away from the push plate 15 in close contact with both second sliders 26. Then manually rotate the handwheel 19. Since the handwheel 19 is fixedly connected to the lead screw 20, the lead screw 20 is rotatably connected to the U-shaped plate 21, and the U-shaped plate 21 is fixedly connected to the test bench 12, the lead screw 20 rotates on the top of the U-shaped plate 21.

[0058] When the lead screw 20 rotates on the top of the U-shaped plate 21, since the first slider 23 is threadedly connected to the lead screw 20, the first slider 23 is also slidably connected to the outer walls of the two guide rods 22, the connecting plate 24 is fixedly connected to the first slider 23, both push rods 25 are fixedly connected to the connecting plate 24, and the other ends of both push rods 25 are fixedly connected to the push plate 15, the push plate 15 is driven to move towards the end close to the wiring block 14 until the push plate 15 contacts the end of the wiring block 14 away from the second slider 26. Then rotate the handwheel 19 to continue driving the push plate 15 to push the wiring block 14 towards the end close to the wiring seat 13, thus facilitating the interface 46 on the wiring block 14 to approach the plug 45 on the wiring seat 13.

[0059] When the push plate 15 pushes the wiring block 14 towards the end close to the wiring seat 13, that is, while the interface 46 on the wiring block 14 approaches the plug 45 on the wiring seat 13, since the outer wall of the end of the wiring block 14 away from the push plate 15 is in close contact with both second sliders 26, the second sliders 26 slide towards the end close to the wiring seat 13 inside the chute. Since one end of the limiting rod 28 is fixedly connected to the second slider 26, the other end of the limiting rod 28 passes through the chute and extends outside the overlapping plate 16, and the telescopic spring 27 is sleeved on the limiting rod 28, the limiting rod 28 slides towards the end close to the wiring seat 13 inside the chute and causes the telescopic spring 27 to change from the initial state to the tense state.

[0060] While the limiting rod 28 slides towards the end close to the wiring seat 13 inside the chute, since the push block 29 is fixedly connected to the end of one of the limiting rods 28 away from the second slider 26, the L-shaped plate 30 is fixedly connected to the outer wall of the push block 29, and the pull rod 31 is fixedly connected to the end of the L-shaped plate 30 away from the push block 29, the pull rod 31 moves towards the end away from the test bench 12.

[0061] When the pull rod 31 moves towards the end away from the detection table 12, since the end of the pull rod 31 away from the L-shaped plate 30 is fixedly connected to the first top block 32, and the first top block 32 is slidably connected to the detection table 12 through a sliding column 37, the first top block 32 slides towards the end close to the connection base 13 on the top of the detection table 12. Since the second top block 33 is slidably connected to the first top block 32, the second top block 33 is in contact with the first top block 32, and both the first top block 32 and the second top block 33 are wedge-shaped structures. The second top block 33 is fixedly connected to the bottom of the lifting frame 36 through a top rod 34, and the insertion rod 35 is fixedly connected to the top of the lifting frame 36. Avoidance grooves 38 are designed on the outer walls of two pressure rods 17 close to the lifting frame 36. The insertion rod 35 is inserted into the two avoidance grooves 38. Two pressure rods 17 close to the lifting frame 36 are respectively rotatably connected to two support plates through a rotating shaft 18. Then, when the insertion rod 35 is jacked up, the two pressure rods 17 close to the lifting frame 36 are driven to rotate around the rotating shaft 18 towards the end close to the top of the connection block 14, that is, rotate downward. When the interface 46 on the connection block 14 is successfully docked with the plug 45 on the connection base 13, the two pressure rods 17 close to the lifting frame 36 rotate downward synchronously to press one end of the top of the connection block 14, realizing the limit of one end of its top.

[0062] While two pressure rods 17 close to the lifting frame 36 rotate around the rotating shaft 18 towards the end close to the top of the connection block 14, since two synchronous pulleys 43 are respectively fixedly connected to the hinge shaft and one rotating shaft 18 close to the lifting frame 36, the two synchronous pulleys 43 are sleeved through a synchronous belt 40. The first gear 41 and the second gear 42 are respectively fixedly connected to the hinge shaft and the other rotating shaft 18, and the first gear 41 and the second gear 42 are meshed and connected. Then, the other two pressure rods 17 synchronously rotate around the other rotating shaft 18 towards the other end close to the top of the connection block 14, that is, rotate downward. When the interface 46 on the connection block 14 is successfully docked with the plug 45 on the connection base 13, the other two pressure rods 17 rotate downward synchronously to press the other end of the top of the connection block 14, realizing the limit of the other end of its top. Then, the four pressure rods 17 are used to completely limit the top of the connection block 14.

[0063] The anti-slip pad 44 can increase the pressure exerted by the pressure rod 17 on the top of the connection block 14 and improve the pressing effect. Preferably, the anti-slip pad 44 is a rubber anti-slip pad 44 or a silica gel anti-slip pad 44.

[0064] When the lifting rod rises, since the top of the lifting frame 36 and the bottom of each anti-disengagement block are respectively in contact with two ends of a return spring 39, the return spring 39 will change from the initial state to the tense state. When the lifting frame 36 is reset, the return spring 39 is no longer in contact and returns to the initial state again.

[0065] When the touch screen test is completed, the wire 47 can be directly unplugged from the touch screen of the terminal block 14, and then the next touch screen test can be carried out. When the terminal block 14 fails or needs to be removed for replacement, the handwheel 19 is manually rotated in the reverse direction, so that the push plate 15 is reset. Then, the terminal block 14 is grasped by hand to unplug its interface 46 from the plug 45 on the terminal block 13, so that the second slider 26 slides towards one end away from the terminal block 13 inside the two chutes, so that the telescopic spring 27 gradually changes from the tightened state to the initial state. Therefore, the synchronous belt 40 drives the four pressure rods 17 to rotate upwards, that is, rotate towards one end away from the terminal block 14. The terminal block 14 is released and removed from the top of the two wiring boards.
