Description

Technical Field

[0001] The utility model relates to the technical field of electronic display devices, in particular to a clamp used for detecting OLED devices. Background Art

[0002] OLED is a device that uses a multi-layer organic thin film structure to generate electroluminescence. It is easy to make and only requires a low driving voltage. These main features make OLED very prominent in meeting the application of flat-panel displays. OLED displays are thinner and lighter than LCDs, have higher brightness, lower power consumption, faster response, higher clarity, better flexibility, and higher luminous efficiency, which can meet consumers' new demands for display technology.

[0003] After the production of OLED devices is completed, they need to be inspected using a fluorescent microscope. During the inspection, a specific fixture is needed to support and position them. However, the existing fixture requires operators to manually position the OLED devices one by one, which is not able to quickly position batches of OLED devices. In addition, the fixture is not convenient for adjusting the position on the OLED device inspection machine, which has great limitations in actual use. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The utility model will now be further described in conjunction with the accompanying drawings.

[0025] Combined with Figure 1-3 The limit assembly limits the position of the clamping plate 3 under the action of the tensioning assembly. The limit assembly includes an adjusting rod 11 and a diamond block 12. An adjusting rod 11 is provided between the transmission plates 10. The adjusting rod 11 is fixedly connected with the diamond block 12. The diamond block 12 fits with the transmission plate 10. The adjusting rod 11 is threadedly connected to the end face of the bottom plate 1. The adjusting rod 11 is exposed from the end face of the bottom plate 1. An end plate 13 is provided on the end of the adjusting rod 11 exposed from the bottom plate, and a convex strip 14 is provided on the end plate 13.

[0026] When in use, the end plate 13 is rotated by the convex strip 14, the end plate 13 drives the adjusting rod 11 to rotate, the adjusting rod 11 drives the diamond block 12 to rotate, the diamond block 12 drives the transmission plate 10 in contact with it to move away, and the transmission plate 10 drives the clamping plate 3 to move away, so that the clamping plate 3 does not clamp the OLED device.

[0027] Combined with Figure 1-3 A slot 2 is provided on the bottom plate 1, and the center of the slot 2 matches the center position of the bottom plate 1. Clamping plates 3 are provided on the left and right sides of the bottom plate 1. The tensioning assembly drives the clamping plates 3 to move relative to each other. The tensioning assembly includes a transmission rod 8 and a tension spring 9. A transmission rod 8 is symmetrically provided in the cavity 4. The transmission rod 8 is slidably connected to the side of the bottom plate 1. The end of the transmission rod 8 that is separated from the bottom plate 1 is exposed, and the end of the transmission rod 8 that is exposed from the bottom plate 1 is connected to the clamping plate 3. A transmission plate 10 is provided on the opposite end of the transmission rod 8. A tension spring 9 is provided between the end face of the cavity 4 on the same side as the transmission plate 10, and a limit assembly is provided between the transmission rods 8.

[0028] The OLED devices to be tested are evenly placed on the base plate 1, and the adjusting rod 11 is rotated to rotate the diamond block 12. The two ends of the short symmetry axis of the diamond block 12 are fitted with the transmission plate 10. At this time, the transmission plate 10 moves relatively under the action of the tension spring 9. The transmission plate 10 drives the clamping plate 3 to move relatively through the transmission rod 8. The clamping plate 3 clamps and positions the OLED devices evenly placed on the base plate 1.

[0029] Combined with Figure 3 The tension spring 9 is sleeved on the outside of the transmission rod 8, the transmission plate 10 is slidably connected to the cavity 4, the direction of the convex strip 14 is consistent with the direction of the diamond block 12, and a soft pad 15 is provided on the opposite side of the clamping plate 3.

[0030] When the end plate is rotated, the convex strip 14 in the same direction as the diamond block 12 clearly indicates the direction of the diamond block 12. The transmission rod 8 guides the extension direction of the tension spring 9, and the transmission plate 10 slidably connected to the cavity 4 assists in guiding the movement direction of the transmission rod. The soft pad 15 on the opposite side of the clamping plate 3 not only ensures the clamping effect of the OLED device, but also protects the edge of the OLED device.

[0031] Combined with Figure 2 Support blocks 5 are provided at the four corners of the lower end surface of the base plate 1, and balls 6 are rollingly connected to the lower ends of the support blocks 5. The balls 6 are exposed from the lower end surface of the support blocks 5. Connecting grooves 7 are provided at the front and rear ends of the lower end surface of the base plate 1, and the connecting grooves 7 are located between the support blocks 5 on the same side thereof.

[0032] When using the detection machine for detection, the connection groove 7 on the lower end surface of the base plate 1 is connected to the slider of the detection machine, and the ball 6 on the support block 5 on the lower end surface of the base plate 1 is rollingly connected to the table of the detection machine. When the slider moves, the position of the fixture can be flexibly adjusted on the detection machine.

[0033] The utility model and its implementation are described, and such description is not restrictive. The drawings are only one of the implementations of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and implementation example similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
