[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] like Figure 1-4 As shown, the present application provides a fixture for facilitating the detection of FOG binding effects, including: a workbench 1, a test clamping assembly 2, a bearing assembly 3 and a driving assembly 5. A guide groove 4 is provided on the top of the workbench 1, and the guide groove 4 is inclined. A protective pad can be provided on the inner wall of the guide groove 4 to protect the workpiece from falling. In addition, the workpiece 1 can be placed on one side of a conveyor belt, and the workpiece sliding from 4 can directly fall onto the conveyor belt for the next processing step of the workpiece. The test clamping assembly 2 is located on the top of the workbench 1, and the test clamping assembly 2 includes a test clamping probe 23 that can move in the vertical direction. The bearing assembly 3 includes a turntable 31, a support plate 32 and The rotating shaft 33 and the support plate 32 are installed to the top of the workbench 1 through the bracket. The two sides of the bracket can be connected to the support plate 32 and the workbench 1 respectively by welding, so that the support plate 32 and the workbench 1 are fixedly connected. The bottom of the turntable 31 is in contact with the top of the support plate 32, and the turntable 31 is provided with a plurality of equidistant placement grooves 36, and the number of placement grooves 36 is preferably four. The turntable 31 is detachably mounted on the rotating shaft 33, and the rotating shaft 33 is rotatably mounted to the top of the workbench 1. The support plate 32 is provided with a discharge groove 37 corresponding to the guide groove 4, and the driving assembly 5 is configured to drive the turntable 31 to make intermittent angular rotation.

[0030] The present solution is a test fixture for performing a lighting test on a bound FOG module and a glass panel after clamping, which can detect the FOG binding effect. The test clamping probe 23 is externally connected with a circuit for connecting to an external display and a control system. When the test clamping probe 23 is clamped and contacted with the FOG module, it can provide voltage to the FOG module and glass panel to be tested, thereby performing testing work and facilitating the detection of the FOG binding effect.

[0031] Specifically, by placing the FOG module and glass panel to be tested in the placement groove 36, the drive assembly 5 is used to drive the turntable 31 to intermittently rotate 90°. When the FOG module and the glass panel move to the bottom of the test clamping assembly 2, the test clamping probe 23 moves downward in the vertical direction to clamp the FOG module. At the same time, the test clamping probe 23 contacts the FOG module and cooperates with the test platform 38 located below to perform the test. After the test is completed, the drive assembly 5 is used again to drive the turntable 31 to rotate 90°. At this time, the positions of the FOG module and the glass panel correspond to the position of the unloading groove 37, so that they lose support and automatically fall to the guide groove 4 below, thereby achieving the purpose of automatic unloading. However, during the unloading process, the adjacent FOG modules and glass panels to be tested move to the bottom of the test clamping assembly 2 for testing. By repeating the above operations, the staff only needs to complete the loading operation of the workpiece to be tested, and the testing work of the workpiece is not stopped during the loading and unloading process.

[0032] In addition, the size of the placement groove 36 is the same as the size of the FOG module and the glass panel to be tested, so that when the FOG module and the glass panel are placed in the placement groove 36, the purpose of clamping and fixing can be achieved.

[0033] It should be noted that since the turntable 31 and the support plate 32 are in contact with each other, the support plate 32 can provide support for the FOG module and the glass panel placed in the placement groove 36 until the OG module and the glass panel fall from the discharge groove 37. In addition, the turntable 31 needs to be disassembled regularly and the top of the support plate 32 needs to be polished to reduce the influence of the friction between the turntable 31 and the support plate 32 on the test workpiece.

[0034] It is worth noting that when one of the FOG modules and the glass panel does not meet the requirements, the external display connected to the test clamping probe 23 will display and alarm, thereby prompting the staff to manually remove it for subsequent rework.

[0035] like Figure 2 As shown, the test clamp assembly 2 also includes a cylinder 21 and a mounting plate 22. The mounting plate 22 is mounted to the top of the workbench 1. The mounting plate 22 can be fixed to the top of the workbench 1 by bolts. The cylinder 21 is mounted to the top of the mounting plate 22. The cylinder 21 is also fixed to the top of the mounting plate 22 by welding, and the output end of the cylinder 21 is connected to the test clamp probe 23.

[0036] In this embodiment, the provided cylinder 21 can control the test clamping probe 23 to move in the vertical direction, thereby completing the clamping and testing work.

[0037] like Figure 3-4 As shown, a through hole is opened on the support plate 32 and located at the center position, and the rotating shaft 33 passes through the through hole. A test platform 38 is embedded and installed on the top of the support plate 32, and the test platform 38 is located directly below the test clamping probe 23. The bearing assembly 3 also includes a fastening nut 35, and the fastening nut 35 is threadedly connected to the rotating shaft 33. A limiting groove 39 is opened on the outer wall of the rotating shaft 33, and a fixing block 310 is installed on the outer surrounding of the rotating shaft 33. The fixing block 310 can be fixedly connected to the rotating shaft 33 by welding. A mounting hole is opened on the turntable 31 and located at the center position, and a limiting block matching the limiting groove 39 is installed on the inner wall of the mounting hole.

[0038] In this embodiment, the purpose of limiting the turntable 31 can be achieved by the mutual cooperation between the limiting block and the limiting groove 39, ensuring that the rotating shaft 33 can drive the turntable 31 to rotate synchronously. In addition, the fastening nut 35 is threadedly connected to the rotating shaft 33 to shorten the distance between the fastening nut 35 and the fixed block 310, so as to achieve the fixed connection between the turntable 31 and the rotating shaft 33. By adopting this detachable connection structure, it is convenient to replace the turntable 31 that matches the FOG module and glass panel to be tested.

[0039] A reserved groove for accommodating the fixing block 310 is provided at the bottom of the rotating disk 31 , thereby ensuring that the rotating disk 31 and the supporting disk 32 can abut against each other.

[0040] like Figure 2 As shown, the driving assembly 5 includes a motor 51 installed on the workbench 1. The motor 51 can be fixed to the top of the workbench 1 by bolts. A driving gear 52 is installed at the output end of the motor 51, and the outer sleeve of the rotating shaft 33 is provided with a driven gear 34 meshing with the driving gear 52.

[0041] In this embodiment, the motor 51 is provided to drive the driving gear 52 to rotate, and the meshing connection between the driving gear 52 and the driven gear 34 is utilized to realize intermittent angular rotation of the turntable 31, so that the workpieces placed in the slots 36 are tested in turn.

[0042] Working principle:

[0043] By placing the FOG module and glass panel to be tested in the placement groove 36, the drive component 5 is used to drive the turntable 31 to rotate intermittently by 90°. When the FOG module and the glass panel move to the bottom of the test clamping component 2, the test clamping probe 23 moves downward in the vertical direction to clamp the FOG module. At the same time, the test clamping probe 23 contacts the FOG module and cooperates with the test platform 38 located below to perform the test. After the test is completed, the drive component 5 is used again to drive the turntable 31 to rotate 90°. At this time, the positions of the FOG module and the glass panel correspond to the position of the unloading groove 37, so that they lose support and automatically fall to the guide groove 4 below, thereby achieving the purpose of automatic unloading. However, during the unloading process, the adjacent FOG modules and glass panels to be tested move to the bottom of the test clamping component 2 for testing. The above operations are repeated, and the staff only needs to complete the loading operation of the workpiece to be tested.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
