Description

Technical Field

[0001] The utility model relates to the technical field of LCD processing, in particular to a patch clamp for LCD processing. Background Art

[0002] LCD stands for liquid crystal display. The structure of LCD is to place a liquid crystal box between two parallel glass substrates. TFT (thin film transistor) is set on the lower substrate glass, and color filter is set on the upper substrate glass. The rotation direction of the liquid crystal molecules is controlled by changing the signal and voltage on the TFT, thereby controlling whether the polarized light of each pixel is emitted or not to achieve the display purpose.

[0003] When some small workshops (small factories) produce small toys or devices related to LCD, due to the high price of chip mount machines, LCD panels and electronic components are mostly installed on the panels manually, so the panels need to be clamped and positioned. The current clamps clamp the panels by manually driving the screws to rotate, and the handles need to be turned manually multiple times, which is very inconvenient and inefficient to use in practice. Therefore, the present application proposes a chip mount clamp for LCD processing. Utility Model Content

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a patch fixture for LCD processing, comprising:

[0021] A fixing block 1, on which a support plate 8 is fixed, and on which a fixing clamping block 9 is fixed; wherein fixing ears can be welded on the fixing block 1 so as to be fixed on the workbench;

[0022] A fixture assembly that is easy to adjust; the fixture assembly includes a T-slot 2 arranged on a fixed block 1, an electromagnet 3 is fixedly connected in the T-slot 2, a power supply 5 and a power switch 6 are installed on the fixed block 1, and the power supply 5 and the power switch 6 are electrically connected in series with the electromagnet 3, so that pressing the power switch 6 can supply power to the electromagnet 3;

[0023] A T-block 4 is slidably connected in the T-slot 2, and also includes two limiting mechanisms installed on both sides of the T-block 4, the limiting mechanism includes a slide groove 11 arranged on the T-block 4, a slider 10 is slidably connected in the slide groove 11, the slider 10 slides against the inner wall of the T-slot 2, a spring 12 is provided between the slider 10 and the slide groove 11, one end of the spring 12 is fixedly connected to the slider 10, and the other end of the spring 12 is fixedly connected to the inner wall of the slide groove 11; the spring 12 is in a compressed state, so that the spring 12 generates elastic force on the slider 10, so that the slider 10 is against the inner wall of the T-slot 2, so that the T-block 4 can be limited and it is not easy to move; further explanation is that the T-block 4 is pushed, the movement of the T-block 4 drives the moving clamping block 7 to move and the T-block 4 slides on the electromagnet 3 until the moving clamping block 7 and the fixed clamping block 9 clamp the substrate, and under the action of the spring 12, the slider 10 is against the inner wall of the T-slot 2, so as to achieve the pre-limitation of the T-block 4;

[0024] A magnetic surface is provided at the bottom of the T-shaped block 4, and the magnetic surface is a magnetic material fixed at the bottom of the T-shaped block 4. If it is a magnetic block, the magnetic block and the electromagnet 3 are arranged with opposite magnetic poles. The upper end of the T-shaped block 4 is fixed with a movable clamping block 7 that cooperates with the fixed clamping block 9 to clamp the patch, and the fixed clamping block 9 and the movable clamping block 7 are the same size.

[0025] The detailed working process of the utility model is as follows:

[0026] 1. When in use, the staff puts the substrate between the fixed clamp block 9 and the movable clamp block 7, and then pushes the T-block 4. The movement of the T-block 4 drives the movable clamp block 7 to move and the T-block 4 slides on the electromagnet 3 until the movable clamp block 7 and the fixed clamp block 9 clamp the substrate. Under the action of the spring 12, the slider 10 abuts against the inner wall of the T-slot 2 to achieve the pre-limit of the T-block 4. Then, the power switch 6 is pressed. At this time, the electromagnet 3 is energized to adsorb and position the T-block 4, so that the movable clamp block 7 can be positioned. In this way, the movable clamp block 7 and the fixed clamp block 9 can stably clamp and position the substrate, so as to install the LCD panel and electronic components;

[0027] 2. In this way, the angle of the panel can be adjusted and positioned to meet the installation habits of the staff during installation;

[0028] 3. After installation, turn off the power switch 6 and slide the T-block 4 to remove the substrate;

[0029] 4. In summary, the utility model can realize positioning by moving the T-block 4 so that the movable clamping block 7 and the fixed clamping block 9 clamp the substrate and pressing the power switch 6. The substrate can be removed by turning off the power switch 6 and sliding the T-block 4. The operation is simple and convenient, avoiding the disadvantages of the prior art of shaking the handle to drive the screw to complete clamping and low efficiency.
