[0037] The following by specific embodiment explains the embodiment of the utility model, the person skilled in the art can easily understand the other advantages and effects of the utility model from the content disclosed in the specification.

[0038] Please refer to Figure 1It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention.

[0039] like Figure 1 As shown, this embodiment provides a fixing fixture for fixing a glass plate. The fixing fixture includes a carrier plate 1, a pressure strip assembly 2, and a limiting member 3. A circuit board B is provided on the edge of the glass plate A. The carrier plate 1 is used to support the glass plate A. The limiting member 3 is fixed on the carrier plate 1 and protrudes from the upper surface of the carrier plate 1 to fix the glass plate A in the circumferential direction. The pressure strip assembly 2 is disposed on the upper surface of the carrier plate 1 and close to the glass plate A to fix the circuit board B on the edge of the glass plate A. The pressure strip assembly 2 includes at least a pressure strip 21 and a rotating shaft 22. The rotating shaft 22 is fixed to the upper surface of the carrier plate 1, and one side of the pressure strip 21 is connected to the rotating shaft 22. The pressure strip 21 fixes the circuit board B by magnetic attraction.

[0040] Before cleaning TFT glass using a flatbed cleaning machine, the TFT glass needs to be secured. The operator first flips the pressure strip 21 of the pressure strip assembly 2 outwards relative to the center of the carrier plate 1, placing the glass on the carrier plate 1. The glass plate A is then fixed in place by the limiting member 3. Next, the pressure strip 21 is flipped inwards to cover the circuit board B at the edge of the TFT glass plate A, and the circuit board B is secured by magnetic attraction to prevent movement. After securing the TFT glass, the fixture with the glass plate is placed into the inlet of the flatbed cleaning machine for cleaning. After cleaning, the pressure strip 21 of the pressure strip assembly 2 is flipped outwards relative to the center of the carrier plate 1, and the TFT glass is removed.

[0041] This application does not specifically limit the size, shape, or material of the carrier plate 1. Regarding the size and shape of the carrier plate 1, any shape and size that can accommodate commonly used TFT glass specifications in the prior art and is suitable for the cleaning process of commonly used flatbed cleaning machines is acceptable. For example, the carrier plate 1 can be square, rectangular, etc., with a length of 33–72 cm and a width of 28–60 cm. In a... Figure 1In the specific embodiment shown, the carrier plate 1 is 60cm long and 60cm wide. As for the material of the carrier plate 1, any material that can meet the function of supporting TFT glass and will not interfere with the magnetic field is acceptable, such as stainless steel and aluminum alloy. Figure 1 In the specific embodiment shown, the carrier plate 1 is a stainless steel carrier plate.

[0042] This application does not specifically limit the method of fixing the limiting member 3 on the carrier plate 1, as long as it is a method in the prior art that can fix the limiting member 3. As an example, in a... Figure 1 In the specific embodiment shown, the limiting member 3 is embedded in the carrier plate 1 and protrudes from the upper surface of the carrier plate 1, thereby achieving circumferential limiting of the glass plate A.

[0043] like Figure 1 As shown, in one specific embodiment, the pressure strip assembly 2 further includes a magnetic suction assembly 23, which includes a fixed magnetic suction member and a movable magnetic suction member. The fixed magnetic suction member is disposed on the upper surface of the carrier plate 1, and the movable magnetic suction member is disposed on the pressure strip 21, with the fixed and movable magnetic suction members correspondingly arranged. The magnetic attraction of the fixed and movable magnetic suction members is used to attract the pressure strip 21 onto the carrier plate 1 to prevent it from shaking.

[0044] As an example, the movable magnetic element can be fixedly disposed on the lower surface and / or upper surface of the pressure strip 21, or it can be embedded inside the pressure strip 21. In a case such as Figure 1 In the preferred embodiment shown, the movable magnetic suction element is fixedly disposed on the lower surface of the pressure strip 21.

[0045] More specifically, the pressure strip 21 is a pressure strip that will not interfere with the magnetic attraction force; it can be an aluminum alloy pressure strip or a stainless steel pressure strip. In a... Figure 1 In the preferred embodiment shown, the pressure strip 21 is a stainless steel pressure strip.

[0046] In one specific embodiment, any pressure strip assembly 2 has at least two magnetic suction components 23. For example, it can have two, three, four, five, etc. As an example, such as... Figure 1 As shown, any pressure strip assembly 2 has two magnetic suction components 23. More specifically, the magnetic suction components 23 are symmetrically distributed on the pressure strip 21 near its edge. This better secures the circuit board B and prevents it from shaking.

[0047] In actual use, the operator first flips the pressure strip 21 of the pressure strip assembly 2 outward relative to the center of the carrier plate 1, so that the fixed magnetic suction part and the movable magnetic suction part are separated. After the TFT glass is placed, the pressure strip is flipped inward so that the fixed magnetic suction part and the movable magnetic suction part come into contact and generate magnetic attraction force, so that the circuit board B covering the edge of the fixed TFT glass plate A does not shake.

[0048] like Figure 1 As shown, in a specific embodiment, the pressure strip assembly 2 further includes a fixing member 24, which is disposed at both ends of the rotating shaft 22 to fix the rotating shaft 22.

[0049] This application does not specify the particular form or method of fixing the fastener 24, as long as it can fix the rotating shaft 22 to the carrier plate 1. For example, it can be a bushing fastener, a hinge fastener, or a pivot fastener, etc. Figure 1 In the specific embodiment shown, the fixing member 24 is a bushing fixing member. The bushing fixing member is provided on the carrier plate 1 and distributed at both ends of the rotating shaft 22. The rotating shaft 22 passes through the bushing fixing member and is thus snapped and fixed.

[0050] like Figure 1 As shown, in a specific embodiment, a limiting member 3 is provided on any side of any right angle of glass plate A.

[0051] like Figure 1 As shown, in a specific embodiment, the number of limiting members 3 is ≥4, and there is at least one limiting member 3 at any right angle of the glass plate A.

[0052] This application does not specifically limit the shape and structure of the limiting member 3, as long as it can achieve circumferential limiting of the glass plate A in the prior art. For example, the limiting member 3 can be a limiting post, a linear limiting baffle, a right-angle limiting baffle, etc.

[0053] As an example, in a... Figure 1 In the specific embodiment shown, the limiting member 3 is a limiting post, and there are 8 limiting members 3; and one limiting post is provided on any side of any right angle of the glass plate A.

[0054] As an example, in another specific embodiment, the limiting member 3 is a right-angled limiting baffle, and there are 4 limiting members 3, with one right-angled limiting baffle provided at any right angle of the glass plate A.

[0055] like Figure 1 As shown, in a specific embodiment, the pressure strip assembly 2 is located on the outside of the limiting member 3, and is configured to correspond to the number and position of the circuit boards B on the edge of the glass plate A.

[0056] In one specific embodiment, the pressure strip assembly 2 consists of 1 to 4 pieces. For example, there can be 1, 2, 3, or 4 pieces. As an example, Figure 1 As shown, there are two pressure strip components 2.

[0057] like ​As shown, in one specific embodiment, the pressure strip 21 does not contact the glass plate A, thus completely avoiding the problem of the pressure strip scratching the glass plate A.

[0058] In summary, the aforementioned fixing fixture for securing glass plates in this invention has a simple structure and is easy to operate. It not only secures the circuit board attached to the edge of the glass plate, preventing significant glass movement and damage during cleaning, but also solves the problem of scratching the glass surface when disassembling the pressure strip assembly in existing technologies by incorporating a pivot. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
