[0029] The loading plate 311 includes a loading platform and a mounting portion, the rotating assembly and the pressing assembly are fixedly connected to the mounting portion, the screen to be tested is fixed through the loading platform, and a plurality of suction holes are provided on the loading platform.

[0030] The pressing assembly includes a pressing plate 312 and a fixed plate 313, and the pressing plate 312 and the fixed plate 313 are movably connected via a connecting shaft. The fixed plate 313 is fixedly connected to the mounting portion, and the pressing plate 312 is connected to the rotating assembly.

[0031] Preferably, a limit block is provided on the fixed plate 313 or the pressing plate 312. When the pressing plate 312 rotates and presses to a certain extent, the limit block simultaneously contacts the pressing plate 312 and the fixed plate 313 to prevent the pressing plate 312 from further pressing. The limit block is used to limit the pressing degree between the pressing plate 312 and the fixed plate 313 to avoid damage to the detection screen caused by over-tight pressing of the pressing plate 312 and the fixed plate 313. The limit block is preferably made of elastic material such as rubber to reduce the impact caused during the pressing process.

[0032] Preferably, a magnetic group is further provided between the fixed plate 313 and the pressing plate 312, and the magnetic group provides magnetic attraction between the fixed plate 313 and the pressing plate 312, so as to ensure the stability of the pressing state between the fixed plate 313 and the pressing plate 312 after the pressing plate 312 and the fixed plate 313 are pressed together.

[0033] Generally, the terminal part of the screen to be detected is arranged between the pressing plate 312 and the fixing plate 313, and a pressing soft board is also arranged on the pressing plate 312, and a plurality of pressing points are also arranged on the pressing soft board, and each pressing point is arranged correspondingly to each pad point on the terminal part. When the pressing plate 312 and the fixing plate 313 are pressed together, the pressing points and the pad points are in contact with each other, so as to realize lighting of the screen to be detected.

[0034] By setting the limit block and the magnetic group, under the condition of ensuring the corresponding contact between the pressing point and the pad point, the limit block limits the pressing action and the magnetic group ensures the pressing state, thereby achieving a better pressing effect.

[0035] The rotating assembly includes at least one transmission shaft 314, the transmission shaft 314 is rotated by a brake member 315, and the transmission shaft 314 is fixed on the mounting portion through a bearing seat. The brake member 315 can be a rotating motor or a rotating cylinder.

The swing rod 316 is fixedly arranged on the transmission shaft 314, and the two ends of the connecting rod 317 are respectively connected to the swing rod 316 and the pressing plate 312. Specifically, the end of the connecting rod 317 is movably connected to the swing rod 316 through a first rotating shaft, and is movably connected to the pressing plate 312 through a second rotating shaft. The rotation of the transmission shaft 314 drives the swing rod 316 to swing around the axis of the transmission shaft 314, thereby pushing the connecting rod 317, and the two ends of the connecting rod 317 rotate around the first rotating shaft and the second rotating shaft respectively, thereby realizing the rotation of the pressing plate 312 around the connecting shaft to complete the pressing action.

[0037] like Figure 3 As shown, Figure 3 The figure is a view of the connection structure of the detection fixture; generally, the transmission shaft 314 is cylindrical, and a plane groove is provided on the outer circumferential surface of the transmission shaft 314, and the plane groove extends along the axial direction of the transmission shaft 314. The swing rod 316 is fixedly provided on the plane groove so that the swing rod 316 and the plane groove surface are in contact, thereby ensuring that the connection state between the transmission shaft 314 and the swing rod 316 is stable. Specifically, a plurality of first connection holes 319 are evenly distributed in the plane groove along the axial direction of the transmission shaft 314, and correspondingly, a first fixing hole is also provided on the swing rod 316, and a bolt passes through the first fixing hole and is threadedly connected to the first connection hole 319, thereby realizing the connection between the swing rod 316 and the transmission shaft 314.

[0038] Preferably, the mounting portion is also provided with a plurality of second connection holes 320 , the fixing plate 313 is provided with a second fixing hole, and bolts pass through the second fixing holes and are threadedly connected to the second connection holes 320 , thereby achieving connection between the fixing plate 313 and the mounting portion.

[0040] Generally, the thickness of the mounting portion is smaller than the thickness of the stage, thereby forming a boss structure. The fixing plate 313 is mounted on the mounting portion so that the end surface of the fixing plate 313 is flush with the end surface of the stage, facilitating the placement of the screen to be tested on the fixing plate 313 and the stage.

[0041] Embodiment 3

[0042] In this embodiment, three transmission shafts 314 are provided, and the ends of the three transmission shafts 314 are connected to form a U-shaped structure. Specifically, the transmission shafts 314 are connected to each other through a gear set 318, and the brake 315 is connected to one of the transmission shafts 314. The brake 315 drives one of the transmission shafts 314 to rotate, and the coordinated rotation of the three transmission shafts 314 is achieved through the transmission effect of the gear set 318. The gear set 318 is generally configured as a helical gear, so that the two connected transmission shafts 314 are arranged perpendicular to each other.

[0043] The mounting portion is also provided with a positioning block, the positioning end surface of which can be closely fitted into the plane groove, thereby limiting the rotation state of the transmission shaft 314. Through the provision of the positioning block, each transmission shaft 314 can be in the initial state of the plane groove being vertically arranged during installation, that is, after installation, the pressing plate 312 connected to the transmission shaft 314 and the fixing plate 313 connected to the mounting portion are in an open state perpendicular to each other.

[0044] By setting up multiple transmission shafts 314, and connecting each transmission shaft 314 through the gear set 318, and fixing the pressure plate 312 on any transmission shaft 314, the pressing operation can be completed under the drive of the brake member 315, so that the pressing assembly can be set at different positions, so that it can be suitable for screen detection in various directions of different structures.

[0045] Embodiment 4

[0046] To ensure that the dual-station detection mechanism is suitable for detecting different screens, the support base 37 includes a support plate 371, a first bracket 372 and a second bracket 373. The support plate 371 is connected to the upper end of the pillar 36. The first bracket 372 and the second bracket 373 are both arranged on the support plate 371. The first detection group 39 is arranged on the first bracket 372. The second detection group 40 is arranged on the second bracket 373. The second horizontal movement group 41 is arranged on the support plate 371.

[0047] like Figure 4 As shown, Figure 4 It is a structural view of the upper frame; preferably, a first adjustment plate 374 is provided on the first bracket 372, and a second adjustment plate 375 is provided on the second bracket 373, the first adjustment plate 374 and the second adjustment plate 375 are perpendicular to the support plate 371 and perpendicular to the horizontal movement direction of the second detection platform 38; the first adjustment plate 374 is connected to the first detection group 39 through a first adjustment moving group, and the second adjustment plate 375 is connected to the second detection group 40 through a second adjustment moving group, the first detection group 39 can be horizontally moved along the extension direction of the first adjustment plate 374 through the first adjustment moving group, and the second detection group 40 can be horizontally moved along the extension direction of the second adjustment plate 375 through the second adjustment moving group, so that the first detection group 39 and the second detection group 40 can be fine-tuned, which is convenient for the detection of the screen to be tested placed at different positions on the detection fixture 31.

[0048] Preferably, the second bracket 373 is also provided with a third horizontal moving group 42, and the third horizontal moving group 42 has the same horizontal moving direction as the first horizontal moving group 34 and the second horizontal moving group 41, so that the second detection group 40 can be moved in the horizontal direction by the third horizontal moving group 42, thereby reducing the setting length of the second horizontal moving group 41.

[0049] Since the second horizontal moving group 41 is arranged on the support plate 371, the setting length of the second horizontal moving group 41 directly affects the size of the support plate 371. At the same time, since the first detection group 39 is also arranged on the support plate 371, in order to realize the mobile detection of the first detection platform 33, the size of the support plate 371 also affects the size setting of the lower frame. In order to ensure that the detection devices on the two stations of the double-station detection mechanism can be suitable for detection on different screens, a larger relative detection displacement needs to be set between the detection device and the screen to be tested at the detection position.

[0050] The first detection group 39 is fixed on the support plate 371, and the relative displacement between the screen to be tested on the first detection platform 33 and the first detection group 39 can be adjusted by the first horizontal moving group 34. The relative displacement of the first detection group 39 is only affected by the length of the first horizontal moving group 34, that is, the first horizontal moving group 34 can achieve a larger relative detection displacement at the detection position by increasing a little length while ensuring that the first detection platform 33 is switched between the material receiving position and the detection position.

[0051] Since the second horizontal moving group 41 is arranged on the support plate 371, the size of the support plate 371 directly affects the size setting of the lower frame. The length of the second horizontal moving group 41 only ensures the completion of the switching of the second detection platform 38 between the material receiving position and the detection position. The second detection group 40 is adjusted by setting the third moving group, so as to minimize the overall size of the double-station detection mechanism and enable the second detection group 40 to have a larger relative detection displacement at the detection position, so that the detection devices on the two stations of the double-station detection mechanism can be suitable for detection on different screens.

[0052] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
