DETAILED DESCRIPTION

At the left and right ends of the connecting plate 12, the connecting member 15 is connected between the sliding blocks 121 which are symmetrically arranged on the left and right sides, and a handle is arranged on the side of the connecting member 15 away from the connecting plate 12. The detection head 16 is respectively clamped on the side of the sliding block 121 away from the connecting plate 12, and the sliding members 131 are respectively fixedly connected to the front end of the connecting plate 12. The sliding members 131 are symmetrically arranged on the left and right sides of the sliding member 131. The extrusion member 13 is slidably connected to the left and right ends of the sliding member 131. An inclined surface is arranged below the extrusion member 13. One end of the compression spring 14 is fixedly connected to the sliding member 131, and the other end of the compression spring 14 is fixedly connected to the extrusion member 13. The left and right sides of the detection frame 1 are rotatably connected to the transmission shaft 181 which is symmetrically arranged front and back. The first sliding frame 110 is slidably connected between the transmission shafts 181 which are symmetrically arranged front and back. The belts 19 are all wound between the transmission shafts 181 which are symmetrically arranged front and back through the transmission wheel. The two extrusion springs 18 are all wound on the same transmission shaft 181, and one end of the extrusion spring 18 is fixedly connected to the first sliding frame 1 On the movable frame 110, the other end of the extrusion spring 18 is fixedly connected to the transmission shaft 181, and the two left and right symmetrically arranged guide frames 172 are fixedly connected to the left and right sides of the detection frame 1, and the front and rear two symmetrically arranged guide frames 172 are slidably connected with a clamping member 17, and the front and rear ends of the clamping member 17 are provided with inclined panels, and the clamping member 17 is extruded and matched with the liquid crystal display screen, and the moving members 171 are fixedly connected to the outside of the clamping member 17, and the moving member 171 is extruded and matched with the inclined surface of the extrusion member 13.

[0038] When it is necessary to inspect the LCD display, first, the inspection head 16 needs to be clamped on the sliding block 121 and the display connector is placed on the belt 19 with the display connector facing upward, so that the display is located between the two symmetrically arranged clamping members 17. At this time, the display is in a tilted state, and the display interface is located obliquely above the display. Then, the telescopic end of the multi-section electric push rod 11 is controlled to extend. The extension of the telescopic end of the multi-section electric push rod 11 will drive the connecting plate 12 to move downward, and the downward movement of the connecting plate 12 will drive the sliding block 121 to move downward, and the sliding block 121 will drive the inspection head 16 to move downward. When the sliding block 121 moves downward, it will drive the sliding member 131 to move downward, and the sliding member 131 will drive the extruding member 13 to move downward as well. 13 moves downward to squeeze the moving member 171. Under the squeezing action of the squeezing member 13, the moving member 171 moves inward, and the moving member 171 drives the clamping member 17 to move inward as well. The clamping members 17 on both sides move inward to squeeze the display. Under the joint squeezing of the clamping members 17, the display slowly rotates from the inclined state to the vertical state in which the belt 19 is perpendicular. In the process of the display being converted from the inclined state to the vertical state, due to the friction between the display and the belt 19, the display drives the belt 19 and the first sliding frame 110 to move left and right on the transmission shaft 181. Finally, the display is in the vertical state under the squeezing action of the clamping member 17. In the process of the clamping member 17 squeezing the display to the vertical state, the display The bottom of the device will move left and right. The device moves together with the display through the belt 19 and the first sliding frame 110, so that the bottom of the display will not move directly on the component by friction, thereby avoiding wear on the bottom of the display during the movement of the display. When the display is in a vertical state, the interface of the display will be directly above. When the display is in a vertical state, the sliding member 131 continues to move downward, and the compression spring 14 will be compressed, so that the clamping member 17 will not continue to squeeze the display, thereby avoiding damage to the display due to continued squeezing. Then the telescopic end of the multi-section electric push rod 11 can be controlled to stop extending. At this time, the staff can pull the handle on the connecting member 15, and the connecting member 15 will move forward and backward. The forward and backward movement of the connecting member 15 will drive the sliding block 121 to move forward and backward , the sliding block 121 moves forward and backward, which will drive the detection head 16 to move forward and backward. When the detection head 16 is just above the display interface, stop pulling the handle of the connecting member 15, and continue to control the telescopic end of the multi-section electric push rod 11 to extend. The detection head 16 will continue to move downward and insert into the interface of the display. At this time, the telescopic end of the multi-section electric push rod 11 can be controlled to move. After the detection head 16 is inserted into the interface of the display, the display can be tested. After the test is completed, continue to control the telescopic end of the multi-section electric push rod 11 to move upward. The telescopic end of the multi-section electric push rod 11 will drive the connecting plate 12 to move upward, and the connecting plate 12 will drive the sliding block 121 to move upward, thereby driving the connecting member 15 and the sliding member 131 to move upward.The upward movement of the sliding member 131 will drive the extruding member 13 to move upward, the compressed compression spring 14 will stretch, the extruding member 13 will continue to move upward, the inclined surface of the extruding member 13 will gradually separate from the clamping member 17, and the inclined surface of the extruding member 13 will no longer squeeze the clamping member 17. The upward movement of the sliding block 121 will drive the detection head 16 to move upward, and the detection head 16 will be pulled out of the display when it moves upward. Finally, the staff can move the inclined panel on the clamping member 17 outward to make the clamping member 17 move outward and reset. Through the above operations, the detection head 16 can be inserted into the interface of the display and pulled out of the display.

[0039] Embodiment 2: Based on embodiment 1, Figure 5-Figure 8 As shown, it also includes a stabilizing mechanism for stabilizing the display, the stabilizing mechanism includes a fixing frame 2, a rack 21, a positioning member 22, a first guide member 23, a pushing member 24, a pressure spring 25, a one-way gear 26, a lifting member 27, a fixing member 28, a first torsion spring 29, a release member 210, a second torsion spring 211, a rotating rod 212 and a ratchet 213, the left and right sides of the connecting plate 12 are fixedly connected to two fixing frames 2 symmetrically arranged front and back, and the racks 21 are fixedly connected to the fixing frames 2 away from the connecting plate 12. At one end, the lifting members 27 are fixedly connected to the outer side of the rack 21, the left and right sides above the detection frame 1 are fixedly connected with the front and rear symmetrically arranged clamping members 22, the rotating rod 212 is rotatably connected to the clamping member 22 on the side close to the fixed frame 2, the first guide members 23 are fixedly connected to the rotating rod 212, the pushing members 24 are slidably connected to the first guide members 23, one end of the pressure spring 25 is fixedly connected to the first guide member 23, and the other end of the pressure spring 25 is fixedly connected to the pushing member 24 The fixing members 28 are fixedly connected to the side of the positioning member 22 away from the detection frame 1, the release members 210 are rotatably connected to the fixing member 28 at one end away from the positioning member 22, the release member 210 is pressed and matched with the lifting member 27, and a baffle is provided on the fixing member 28, the baffle is pressed and matched with the release member 210, and the baffle is used to prevent the release member 210 from rotating outward, and the first torsion spring 29 is wound on the fixing member 28, one end of the first torsion spring 29 is fixedly connected to the fixing member 28, and the other end of the first torsion spring 29 is The ratchet 213 is fixedly connected to the release member 210, and is fixedly connected to the middle position of the rotating rod 212. The ratchet 213 is squeezed and matched with the release member 210. The second torsion spring 211 is wound on the rotating rod 212, and one end of the second torsion spring 211 is fixedly connected to the locking member 22, and the other end of the second torsion spring 211 is fixedly connected to the rotating rod 212. The one-way gear 26 is fixedly connected to the rotating rod 212 at one end away from the second torsion spring 211, and the one-way gear 26 is meshed with the rack 21.

[0040] When the LCD interface and the detection head 16 are tightly connected, pulling the detection head 16 out of the interface of the display will pull the display, which may easily cause damage to the display. Therefore, when pulling out the detection head 16, the display needs to be stabilized, such as Figure 6, the pushing member 24 is in a horizontal state. According to the foregoing, when the detection head 16 is inserted into the display, the downward movement of the connecting plate 12 will drive the fixing frame 2 to move downward, and the fixing frame 2 will drive the rack 21 to move downward as well. The downward movement of the rack 21 will drive the one-way gear 26 to rotate outward, and the rotation of the one-way gear 26 will drive the rotating rod 212 to rotate, and the rotation of the rotating rod 212 will drive the first guide member 23 to rotate downward as well. At this time, the second torsion spring 211 is in a force storage state, and the downward rotation of the first guide member 23 will drive the pushing member 24 to rotate downward. The downward rotation of the pushing member 24 will contact the display and fix the display. By setting the pressure spring 25, the push member 24 can be slowed down when it rotates downward to squeeze the display. The push member 24 will continue to lock the display because the upward movement of the connecting plate 12 will also drive the rack 21 to move upward, and the upward movement of the rack 21 will drive the lifting member 27 to move upward. At this time, the release member 210 still restricts the ratchet 213, and the upward movement of the rack 21 drives the outer teeth of the one-way gear 26 to rotate, and the inner gear ring rod of the one-way gear 26 will not rotate, so the rotating rod 212 and the first guide member 23 will not rotate, so that the pushing member 24 will not rotate upward. When the bar 21 continues to move upward and no longer meshes with the one-way gear 26, the detection head 16 has been pulled out of the display. The lifting member 27 continues to move upward to squeeze the release member 210. Under the squeezing action of the lifting member 27, the release member 210 will rotate upward, and the first torsion spring 29 will gradually accumulate force. The rotation of the release member 210 will no longer restrict the ratchet 213. At this time, the second torsion spring 211 is transformed from a force accumulation state to a pressure release state. The second torsion spring 211 will drive the rotating rod 212 to rotate inward. The inward rotation of the rotating rod 212 will drive the first guide member 23 to rotate upward and reset. The upward rotation of the first guide member 23 will drive the pushing member 24 to rotate upward and reset. The upward rotation of the pushing member 24 no longer restricts the display. In this process The middle lifting member 27 continuously squeezes the releasing member 210 upward. When the display needs to be inspected again, the fixing frame 2 will move downward again. The movement of the fixing frame 2 will drive the rack 21 and the lifting member 27 to move downward. The lifting member 27 moves downward and no longer squeezes the releasing member 210. At this time, the first torsion spring 29 will be transformed from a force storage state to a pressure release state. The first torsion spring 29 will drive the releasing member 210 to rotate downward and reset. The releasing member 210 will restrict the ratchet 213 again. In this way, when the detection head 16 is pulled out from the display inner screen, the pushing member 24 will continue to restrict the display inner screen, avoiding the detection head 16 from moving with the display when the detection head 16 is pulled out from the interface of the display, causing damage, and the display can be centered.

[0041] like Figure 9-11As shown, it also includes a guiding mechanism for positioning the display interface, the guiding mechanism includes an extrusion frame 3, a lifting member 31, a fixed plate 32, a second sliding frame 33, a second guide member 34, a guide member 35, a reset spring 36, a positioning member 331 and a straight spring 332, the two extrusion frames 3 are respectively fixedly connected to the front and rear sides of the sliding block 121, the lifting members 31 are slidably connected to the extrusion frame 3, the fixed plate 32 is slidably connected to the lifting member 31, the fixed plate 32 is provided with an inclined surface, the inclined surface of the fixed plate 32 is pressed and matched with the extrusion frame 3, the second guide members 34 are fixedly connected to the lifting member 31 on the side away from the extrusion frame 3, the second guide member 34 is provided with a sliding groove, and the second sliding frame 33 is slidably connected to the lifting member 31. The guide members 35 are fixedly connected to the side of the lifting member 31 away from the extrusion frame 3, and the guide members 35 are slidably connected to the second sliding frame 33. One end of the return spring 36 is fixedly connected to the guide member 35, and the other end of the return spring 36 is fixedly connected to the second sliding frame 33. The positioning members 331 are slidably connected to the lower end of the second sliding frame 33. The positioning members 331 are insulators. The straight springs 332 are wound on the positioning members 331, one end of the straight springs 332 is fixedly connected to the positioning members 331, and the other end of the straight springs 332 is fixedly connected to the second sliding frame 33.

[0042] Because the positions of the display power sockets are different, it is not easy for the detection head 16 to be aligned with the display interface. Therefore, before the detection head 16 is inserted into the interface, the positioning member 331 is first inserted into the display interface to accurately position the display interface, so that the detection head 16 can be accurately inserted into the display interface. Fig.10As shown, when the sliding block 121 drives the detection head 16 to move downward, the extrusion frame 3 will also move downward. The downward movement of the extrusion frame 3 will drive the positioning member 331 and the components below the extrusion frame 3 to move downward. The positioning member 331 moves downward and gradually contacts with the display and squeezes the top of the display. Under the squeezing action of the display, the positioning member 331 stops moving, the straight spring 332 is compressed, and the second sliding frame 33 moves slightly upward, while the lower end of the extrusion frame 3 has not yet contacted the fixed plate 32. At this time, the telescopic end of the multi-section electric push rod 11 can be controlled to stop moving downward, and the staff can pull the connecting piece The handle of the connecting member 15 is pulled, so that the connecting member 15 drives the second sliding frame 33 to move forward and backward, and the forward and backward movement of the second sliding frame 33 drives the extrusion frame 3, the lifting member 31, the positioning member 331 and other parts of the guide mechanism to move forward and backward. When the positioning member 331 moves forward and backward and contacts the interface of the display, the straight spring 332 will stretch and insert into the interface of the display. At this time, the pulling of the handle of the connecting member 15 can be stopped, and then the telescopic end of the multi-section electric push rod 11 can be controlled to move downward, so that the lifting member 31 and the extrusion frame 3 continue to move downward. When the lower end of the lifting member 31 contacts the display, the lifting member 31 will When the movement stops, the extrusion frame 3 will continue to move downward, and the movement of the extrusion frame 3 will squeeze the inclined surface of the fixing plate 32. Under the extrusion effect of the extrusion frame 3, the fixing plate 32 slides in the direction away from the positioning member 331, and the fixing plate 32 slides out of the second sliding frame 33. After the fixing plate 32 slides out of the second sliding frame 33, the fixing plate 32 no longer restricts the second sliding frame 33. At this time, the return spring 36 in the extended state will contract. The contraction of the return spring 36 will drive the second sliding frame 33 to move upward along the sliding groove of the second guide member 34, and the second sliding frame 33 will drive the positioning member 331 to move upward. When the detection head 16 is pulled out from the interface of the display, the sliding block 121 will also drive the detection head 16 to move downward, and the detection head 16 will be inserted into the interface of the display. After the test is completed, the sliding block 121 will drive the detection head 16 to move upward and be pulled out from the interface of the display, and the sliding block 121 will drive the guide mechanism to move upward. At this time, the staff needs to move the second sliding frame 33 downward, and insert the fixing plate 32 into the second sliding frame 33, and re-lock the second sliding frame 33. In this way, the interface of the LCD screen can be accurately positioned, so that the detection head 16 can be smoothly inserted into the interface of the display.

[0043] like Figure 12-Figure 15As shown, it also includes a reset mechanism for reinserting the fixed plate 32 into the second sliding frame 33, the reset mechanism includes a reset member 4, a linear spring 41 and a force storage spring 42, the force storage spring 42 is wound on the fixed plate 32, one end of the force storage spring 42 is fixedly connected to the fixed plate 32, the other end of the force storage spring 42 is fixedly connected to the lifting member 31, the reset member 4 is respectively slidably connected to the front and rear sides of the sliding block 121, the reset member 4 is pressed and fitted with the second sliding frame 33, the upper end of the reset member 4 is pressed and fitted with the detection frame 1, one end of the linear spring 41 is fixedly connected to the reset member 4, and the other end of the linear spring 41 is fixedly connected to the sliding block 121.

[0044] As mentioned above, the staff needs to move the second sliding frame 33 downward and insert the fixing plate 32 into the second sliding frame 33 to re-lock the second sliding frame 33. However, because the inspection of the LCD display is carried out in batches, the resetting work of the fixing plate 32 and the second sliding frame 33 is time-consuming and laborious. Therefore, it is necessary to set a resetting mechanism to automatically reset the fixing plate 32 and the second sliding frame 33. When the detection head 16 is pulled out of the display, the sliding block 121 will drive the extrusion frame 3 to move upward, thereby driving the second sliding frame 33 to move upward. At this time, the second sliding frame 33 has slid to the top of the sliding groove of the second guide member 34. During the upward movement of the second sliding frame 33, the resetting member 4 will gradually contact and squeeze the second sliding frame 33, and the upper end of the resetting member 4 will contact and squeeze the detection frame 1. The linear spring 41 will be compressed, and under the extrusion of the reset member 4, the second sliding frame 33 will move downward and reset. The upward movement of the sliding block 121 will also drive the extrusion frame 3 to move upward. The extrusion frame 3 moves upward and no longer squeezes the fixed plate 32. When the detection head 16 moves downward and is inserted into the interface of the display, the fixed plate 32 moves in the direction away from the second sliding frame 33, and the storage spring 42 will be compressed. At this time, the compressed storage spring 42 extends. The extension of the storage spring 42 will drive the fixed plate 32 to move in the direction close to the reset spring 36. The fixed plate 32 moves and is reinserted into the second sliding frame 33 that slides to the bottom of the sliding groove of the second guide member 34, and the second sliding frame 33 is re-locked. Through the above operation, the fixed plate 32 can be reinserted into the second sliding frame 33 to achieve the resetting of the guide mechanism.

Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
