Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal module testing technology, and specifically relates to a liquid crystal module testing fixture mechanism. Background Technology

[0002] Currently, the testing of LCD modules on the market requires the product to be lit up and placed on a fixture for operation. Fixtures for different sizes are usually designed to switch automatically. However, due to the increasing number of irregular product sizes and the diverse positions of the protrusions on the back, it is becoming increasingly difficult to achieve compatibility during the design process. Some designs can only accommodate multiple fixtures for different sizes, but this design will significantly increase equipment costs, make switching and debugging complex, and improper debugging can cause quality problems such as scratches on the back of the product, which cannot meet the requirements of the rapidly developing market for production efficiency and quality. In addition, if the debugging is not done properly, the protrusions on the back may interfere with the mechanism, causing quality problems such as scratches on the back of the product. Utility Model Content

The suction cup fixing seats can slide along the translation rails and can be fixed to the translation rails by fixing bolts. A suction cup is provided on the top of the suction cup fixing seat.

[0006] A set of side limiting components is also provided on the left and right sides of the base plate. The side limiting components include a side rail and two second slide rails. The second slide rails are parallel to the translation rail. The two ends of the side rail are slidably installed on the two second slide rails by second adjusting screws. Angle fixtures and side limiting parts are installed on the side rails. The side limiting parts have an L-shaped cross section.

[0007] Furthermore, two ground-side trays are installed on the side of the base plate.

[0008] Furthermore, the base plate has several perforations.

[0009] Furthermore, the suction cup holder is made of silicone.

[0010] Furthermore, position dimension scale lines are provided on the first slide rail, the second slide rail, the translation rail, and the side rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a sliding and adjustable first slide rail, translation rail, second slide rail, side rail, and suction cup fixing seat with position adjustment function, this utility model enables the fixture to adapt to products of various sizes and shapes, reducing the need for multiple specific fixtures; the combination of corner fixture and L-shaped side limiting member can provide stable support and ensure that the product is correctly positioned and clamped, preventing movement or displacement during operation; the liquid crystal module detection fixture mechanism of this utility model has high flexibility and adaptability, and can effectively solve the problems encountered in the detection of liquid crystal modules of different sizes and shapes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The present invention will be further described in detail below with reference to the embodiments.

[0017] like Figure 1 and Figure 2 As shown, a specific embodiment of the liquid crystal module testing fixture mechanism provided by this utility model is as follows:

[0018] A liquid crystal module testing fixture mechanism includes a base plate 1, two ground-side sliding plates 2 installed on the side of the base plate 1, two first slide rails 3 installed side by side on the base plate 1, and several translation rails 4 arranged side by side between the two first slide rails 3. The two ends of the translation rails 4 are slidably installed on the two first slide rails 3 by first adjusting screws. Two suction cup fixing seats 6 are installed on the translation rails 4. The suction cup fixing seats 6 can slide along the translation rails 4 and can be fixed to the translation rails 4 by fixing bolts 7. A suction cup 8 is provided on the top of the suction cup fixing seat 6.

[0019] A set of side limiting components is also provided on the left and right sides of the base plate 1. The side limiting components on the left and right sides are symmetrically arranged. The side limiting components include a side rail 9 and two second slide rails 10. The second slide rails 10 are parallel to the translation rail 4. The two ends of the side rail 9 are slidably installed on the two second slide rails 10 by second adjusting screws. Angle fixtures 12 and side limiting parts 13 are installed on the side rail 9. The side limiting parts 13 have an L-shaped cross section.

[0020] It should be noted that the technique of sliding the first adjusting screw and the second adjusting screw onto the slide rail is a conventional technique in the field. By tightening the screws, it can be fixed onto the slide rail, and by loosening them, it can slide on the slide rail.

[0021] When using the LCD module testing fixture mechanism of this embodiment, the side rails 9 on both sides are manually slid according to the production machine type, so that the corner fixtures 12 and the side limiters 13 on the two side rails 9 jointly clamp and position the product. Then, according to the position of the protrusions on the back of the product, the position of the suction cup fixing seat 6 on the translation rail 4 is adjusted to avoid interference from the protrusions. Then, the product is manually picked up and placed on the ground side plate 2. The product is erected, the power cord and signal line are plugged in, and then the product is laid flat on all the suction cups 8 to start the operation.

[0022] Several perforations 14 are provided on the base plate 1. The perforations 14 not only reduce weight but also provide space for managing wires and signal lines, improving the tidiness of the work area. The suction cup holder 6 is made of silicone to prevent scratches from contact with the product. Position dimension scale lines are provided on the first slide rail 3, the second slide rail 10, the translation rail 4, and the side rail 9. The dimension scale lines assist in the position adjustment of fixtures of different sizes.

[0023] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
