Technical Field

[0001] The utility model relates to the technical field of liquid crystal panel detection, in particular to an auxiliary tooling for optical detection of LCD liquid crystal panels. Background Art

[0002] Liquid crystal panel is the material that determines the brightness, contrast, color and viewing angle of liquid crystal display. The price trend of liquid crystal panel directly affects the price of liquid crystal display. The quality and technology of liquid crystal panel are related to the overall performance of liquid crystal display. With the development of science and technology, LCD liquid crystal display panel has more and more applications due to its advantages of good display quality and good picture effect.

[0003] After the production of LCD panels is completed, like conventional LCD panels, they need to undergo a series of tests before they can be put on the market, including optical tests such as bad pixel detection and light leakage detection, as well as other tests such as aging detection. The above tests all require the LCD panels to be connected to an external control system through a connecting line, and then the control system plays a pure color picture on the LCD panel or plays it for a certain period of time for detection. When a large number of LCD panels need to be tested, the LCD panels need to be fixed on the tooling fixture one by one, and then the LCD panels are connected to the external control system in turn. In the prior art, the LCD panels are fixed on a bracket or wall by a fixture, etc. In this process, the fixing process of a large number of LCD panels is relatively cumbersome and takes a lot of time. For this reason, we propose an auxiliary tooling for optical detection of LCD panels. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides an auxiliary tooling for optical inspection of LCD liquid crystal panels. It has the following beneficial effects:

[0014] (1) The auxiliary tooling for optical inspection of LCD liquid crystal panels has two sets of movable jaws in the clamping assembly that can cooperate with the supporting plate to clamp LCD panels with smaller size differences, thereby increasing the scope of use of the device during use. At the same time, the movable socket on the mounting plate can adjust its position, thereby facilitating the connection line on the LCD panel to be plugged into the socket, facilitating unified control of multiple LCD panels inspected in the device.

[0015] (2) The auxiliary tooling for optical inspection of LCD liquid crystal panels can drive the gear to rotate when the supporting plate moves downward under the action of the liquid crystal panel's own gravity. Under the transmission action of the gear, the two rack plates meshing with the gear move toward each other, so that the two clamping claws fixedly connected to the rack plates move closer to each other to clamp the two ends of the liquid crystal panel. On the one hand, the liquid crystal panel can be stably clamped through the cooperation of the supporting plate and the two clamping claws. On the other hand, when the liquid crystal panel is lifted upward, the two clamping claws are automatically released, so that the user can quickly remove multiple liquid crystal panels from the clamping assembly.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-5As shown, an auxiliary tooling for optical inspection of LCD liquid crystal panels includes a mounting frame 1, a plurality of mounting plates 3 are movably mounted inside the mounting frame 1, a support frame 2 is rotatably mounted on the outer wall of the upper end of the mounting frame 1, a socket 6 is slidably mounted on the mounting plate 3, and a clamping assembly 7 is fixedly mounted at the center position of the mounting plate 3;

[0026] The clamping assembly 7 includes a housing 701 fixedly connected to the mounting plate 3, with clamping claws 702 interactively mounted on both ends of the housing 701, and a supporting plate 703 slidably mounted on the bottom surface of the housing 701;

[0027] In the device, the mounting frame 1 is tilted as a whole and is supported by the support frame 2. The multiple mounting plates 3 arranged on the mounting frame 1 can be removed. When the mounting plate 3 is damaged after being used for too long, the mounting plate 3 can be removed and replaced. Between the optical inspection and aging inspection of the liquid crystal panel, the user can place the liquid crystal panel on the clamping assembly 7 arranged on the mounting plate 3. The clamping assembly 7 includes two sets of movable jaws 702 and a set of supporting plates 703. The jaws 702 and the supporting plates 703 can be adjusted to clamp and fix LCD panels of various sizes with similar sizes. At the same time, after the movable socket 6 on the mounting plate 3 is connected to the connecting line of the liquid crystal display panel, the display of the liquid crystal display panel during the inspection can be controlled.

[0028] As shown in the mounting frame 1, the clamping assembly 7 also includes a fixed shaft 707 fixedly installed at the center position inside the shell 701, a gear 706 is rotatably installed on the outer wall of the fixed shaft 707, a torsion spring is arranged at the end of the gear 706, and the two ends of the torsion spring are respectively fixedly connected to the corresponding positions on the fixed shaft 707 and the gear 706, and the two ends of the shell 701 are slidably installed with clamping jaws 702, and rack plates 709 meshing with the gear 706 are fixedly installed on both ends of the shell 701; under the action of the gear 706, when one of the clamping jaws 702 slides inward, the other clamping jaw 702 also moves synchronously, and the two clamping jaws 702 can be opened outward synchronously or moved toward the middle synchronously, and when the two clamping jaws 702 move toward the middle synchronously, the two ends of the liquid crystal panel can be clamped.

[0029] like Figure 5 As shown, fixing rods 704 are fixedly installed at both ends of the shell 701, and a sliding groove 705 matching the fixing rod 704 is opened through the clamping jaw 702, and the fixing rod 704 slides inside the sliding groove 705. The cooperation between the fixing rod 704 and the sliding groove 705 can support and limit the clamping jaw 702.

[0030] like Figure 5As shown, a through slot is formed through the upper end of the supporting plate 703, and a plurality of tooth blocks 708 meshing with the gear 706 are fixedly installed on the inner wall of one side of the through slot. When the supporting plate 703 moves up and down, the plurality of tooth blocks 708 mesh with the gear 706 in turn, so that the gear 706 can rotate. The supporting plate 703 usually moves downward under the gravity of the liquid crystal panel. After the liquid crystal panel is removed, the rotation of the gear 706 under the action of the torsion spring arranged between the gear 706 and the fixed shaft 707 can drive the supporting plate 703 to move upward and return to its initial position.

[0031] like Figure 4 As shown, the clamping jaws 702 and the supporting plate 703 are both L-shaped, and the outer walls of the ends of the clamping jaws 702 and the supporting plate 703 are fixedly connected with rubber pads. The two sets of clamping jaws 702 can clamp and fix the two ends of the liquid crystal panel respectively, and the supporting plate 703 can support the bottom surface of the liquid crystal panel. The rubber pads arranged at the ends of the clamping jaws 702 and the supporting plate 703 can transform the hard contact between the clamping jaws 702, the supporting plate 703 and the liquid crystal panel into elastic contact, thereby avoiding damage to the contact position between the clamping jaws 702, the supporting plate 703 and the liquid crystal panel.

[0032] like Figure 4 As shown, a plurality of elastic cards 4 are fixedly installed on the surrounding side of the mounting plate 3, and a card slot for use with the elastic card 4 is opened on the mounting frame 1. The elastic card 4 itself is elastic and can be snapped into the inside of the card slot on the mounting frame 1. A convex ridge is fixedly installed on the end of the elastic card 4. When the mounting plate 3 needs to be removed from the mounting frame 1, the elastic card 4 can be pulled out from the inside of the card slot by squeezing the convex ridge. When installing the mounting plate 3, it is only necessary to match the elastic card 4 fixedly connected on the mounting plate 3 with the card slot on the mounting frame 1 and press it, so that the mounting plate 3 can be installed on the mounting frame 1. When the mounting plate 3 is damaged and cannot be used, the mounting plate 3 can be replaced.

[0033] like Figure 4 As shown, the outer wall of the mounting plate 3 is provided with a slide rail 5, and a slide rod 8 is slidably installed inside the slide rail 5. The outer wall of the end of the slide rod 8 is fixedly connected to the outer wall of the connector 6 on one side close to the mounting plate 3; the slide rail 5 is arranged in an annular shape, and the slide rod 8 can slide inside the slide rail 5. Then, by toggling the connector 6, the connector 6 can be moved around the clamping assembly 7 along the track of the slide rail 5, and the connector 6 is a track socket, so the connector 6 can be put into use regardless of the position it is moved to on the slide rail 5.

[0034] The working principle of the utility model is as follows: when in use, the user can place a small LCD panel used in a computer or tablet in the device for optical inspection and aging inspection according to the situation, and place multiple LCD panels corresponding to multiple mounting plates 3 on the mounting frame 1, wherein the staff places one end of the LCD panel on the supporting plate 703, and then under the action of the gravity of the LCD panel itself, the supporting plate 703 slides downward, and when the supporting plate 703 moves downward, the multiple tooth blocks 708 fixedly installed in the through groove at the upper end of the supporting plate 703 drive the gear 706 to rotate through the meshing with the gear 706, and when the gear 706 rotates, the rack plates 7 arranged on the upper and lower sides of the gear 706 09 move towards each other under the transmission action of the gear 706, and the clamping claw 702 fixedly connected to the rack plate 709 can move relatively to clamp and fix the two ends of the LCD liquid crystal panel, so that the LCD liquid crystal panel to be tested can be stably placed on the mounting plate 3 which is in an inclined state as a whole. Then, the user can plug the connecting line of the LCD panel into the socket 6, and play the pure color picture on the LCD panel through the system control to perform optical detection of bad pixels and light leakage on multiple LCD display panels. At the same time, the use time of the LCD panel can also be controlled to perform anti-aging detection on the LCD panel. The socket 6 slidably installed on the mounting plate 3 can be adjusted in position according to the different lengths of the connecting lines of different models of LCD panels.
