The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] A positioning fixture for dispensing LCM liquid crystal display screens, such as Figure 1-Figure 4 As shown, it is a first embodiment of the utility model, comprising a fixed plate 1 and a fixed stopper 2 fixedly connected to the fixed plate 1, the fixed stopper 2 is provided with a plurality of positioning mechanisms 4, and the fixed plate 1 is provided with the same number of side limit mechanisms 5 as the positioning mechanisms 4.

[0026] Specifically, the fixing plate 1 is square and can be connected to the equipment by bolts 44. The fixing block 2 is connected to the fixing plate 1 by bolts 44 and can be integrally formed with the fixing plate 1 in other embodiments. The fixing block 2 is provided with two positioning mechanisms 4. The fixing plate 1 is provided with the same number of side limiting mechanisms 5 as the positioning mechanisms 4, and the two side limiting mechanisms 5 are symmetrically arranged with respect to the central axis of the fixing plate 1.

[0027] The positioning mechanism 4 includes a movable stopper 41 slidably connected to the fixed stopper 2 and a plurality of threaded holes 42 transversely arranged on the fixed plate 1, wherein a threaded seat 43 is arranged on the movable stopper 41, a bolt 44 is threadedly arranged on the threaded seat 43, and the bolt 44 is threadedly connected to one of the threaded holes 42;

[0028] Specifically, the fixed stopper 2 is provided with a first slide groove 3 in the shape of a straight line, a movable stopper 41 is slidably connected in the first slide groove 3, a plurality of threaded holes 42 are transversely provided on the fixed plate 1, a threaded seat 43 is fixedly connected to the movable stopper 41, a bolt 44 is threadedly connected to the threaded seat 43, and the bolt 44 is threadedly connected to one of the threaded holes 42;

[0029] The side limiting mechanism 5 includes a first sliding block 52 slidably connected to the fixed plate 1 and a driving component rotatably connected to the fixed plate 1 for driving the first sliding block 52 to move;

[0030] Specifically, a second sliding groove 51 is provided on the fixed plate 1, and a first sliding block 52 is slidably connected to the second sliding groove 51. The driving assembly includes a screw rod 53 rotatably connected to the fixed plate 1, and the screw rod 53 is threadedly connected to the first sliding block 52. A knob 54 is fixedly connected to the end of the screw rod 53 away from the fixed plate 1.

[0031] When the operator needs to use the positioning fixture, the operator can take out an LCM liquid crystal display screen 8 that has not been glued, and then adjust the position of the positioning mechanism 4 according to the type of the LCM liquid crystal display screen 8. The specific operation of adjusting the positioning mechanism 4 is: first, the operator rotates the bolt 44 so that the bolt 44 is no longer located in the threaded hole 42, and then slides the movable stopper 41 according to the type of the LCM liquid crystal display screen 8. After adjusting the movable stopper 41, the operator can screw the bolt 44 back into the threaded hole 42 at the relative position, and then fit one side of the LCM liquid crystal display screen 8 with the movable stopper 41, and at the same time, the other side of the LCM liquid crystal display screen 8 is in contact with the fixed stopper 2, thereby achieving the positioning of the LCM liquid crystal display screen 8 through the action of the movable stopper 41 and the fixed stopper 2, so that the position of the LCM liquid crystal display screen 8 that needs to be glued is exactly located at the point. Below the glue machine, the operator can then rotate the knob 54, the knob 54 drives the screw 53 to rotate, and the screw 53 drives the first sliding block 52 to move in the direction close to the LCM liquid crystal display screen 8, and finally contacts the LCM liquid crystal display screen 8, thereby through the action of the first sliding block 52 and the movable stopper 41, the LCM liquid crystal display screen 8 can be clamped, and the LCM liquid crystal display screen 8 can be effectively prevented from moving at will. After the LCM liquid crystal display screen 8 is glued, the operator only needs to rotate the knob 54 so that the first sliding block 52 no longer contacts the LCM liquid crystal display screen 8, and then take out the glued LCM liquid crystal display screen 8. When it is necessary to replace a different type of LCM liquid crystal display screen 8 for glue dispensing, the operator can adjust the position of the movable stopper 41 according to the above operation to adapt to the model of LCM liquid crystal display screen 8.

[0032] To summarize, by unscrewing the bolt 44 from the threaded hole 42, and then adjusting the position of the movable stopper 41 according to the different models of LCM liquid crystal display screens 8, the positioning of the LCM liquid crystal display screen 8 is achieved, so that the positions where the different models of LCM liquid crystal display screens 8 need to be glued can be located below the glue dispensing machine, which can play a positioning fixture that can achieve the positioning effect for different models of products. At the same time, by rotating the knob 54, the first sliding block 52 is moved in the direction close to the LCM liquid crystal display screen 8, and finally contacts the LCM liquid crystal display screen 8, thereby the LCM liquid crystal display screen 8 can be clamped by the action of the first sliding block 52 and the movable stopper 41, and the LCM liquid crystal display screen 8 can be positioned in three directions by the first sliding block 52, the movable stopper 41 and the fixed stopper 2, thereby achieving the best positioning effect.

[0033] like Figure 4As shown, the first sliding block 52 is provided with a buffer mechanism 6 for protecting the LCM liquid crystal display screen 8, and the buffer mechanism 6 includes a receiving groove 61 opened on the first sliding block 52 and a second sliding block 62 slidably connected to the receiving groove 61, and a plurality of springs 63 are provided between the second sliding block 62 and the first sliding block 52.

[0034] When the first sliding block 52 moves toward the LCM liquid crystal display screen 8, the first sliding block 52 will also drive the buffer mechanism 6 to move, and the second sliding block 62 of the buffer mechanism 6 will contact the side of the LCM liquid crystal display screen 8. Since the second sliding block 62 is slidable and can buffer the LCM liquid crystal display screen 8 through the action of the spring 63, it can effectively prevent the operator from excessively rotating the knob 54, causing the first sliding block 52 to move excessively, thereby excessive clamping causing damage to the LCM liquid crystal display screen 8.

[0035] like Figure 5-Figure 6 As shown, it is the second embodiment of the utility model. This embodiment further includes a release mechanism 7 on the basis of the first embodiment. The release mechanism 7 includes a sliding frame 72 and sliding sleeves 71 arranged on both sides of the fixed plate 1. The two ends of the sliding frame 72 are respectively slidably connected to the two sliding sleeves 71. Racks 73 are arranged on both ends of the sliding frame 72. Gears 74 are fixedly connected to the screw rods 53 of the two side limiting mechanisms 5. The racks 73 mesh with the gears 74 when moving. A handle 75 is fixedly connected to the side of the middle part of the sliding frame 72 away from the fixed plate 1.

[0036] When the operator needs to remove the LCM liquid crystal display screen 8 with glue applied from the positioning fixture, the operator can pull the sliding frame 72 to slide to the outside of the fixed plate 1 through the pull handle 75, and the sliding frame 72 slides to drive the rack 73 to move, and the movement of the rack 73 will engage with the gear 74 to drive the gear 74 to rotate, and the rotation of the gear 74 will drive the screw 53 to rotate, and the rotation of the screw 53 will drive the first sliding block 52 to move away from the LCM liquid crystal display screen 8, and the first sliding block 52 will no longer clamp the LCM liquid crystal display screen 8, so that the operator can take out the LCM liquid crystal display screen 8 with glue applied. It can be seen that it is only necessary to pull the pull handle 75 to drive the sliding frame 72 to move outward, and the two first sliding blocks 52 can be driven to move away from the LCM liquid crystal display screen 8 at the same time, so as to achieve the effect of convenient operation.
