Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a film sticking clamp. Background Art

[0002] The production process of display screens is very long, and they often have to pass through many conveyor belts for transportation. During transportation, it is easy to get scratched by dragging the product. In order to solve the above defects, a protective film is usually applied to the side of the contact surface between the display screen product and the conveyor belt in advance during the production process.

[0003] The existing film sticking fixture has limit slots on the four sides. The film is first placed in the limit slots, and then the glass cover is placed on the film. At this time, employees will use their fingers to press the center of the glass cover to make the center of the glass cover contact with the film first, so as to achieve the effect of discharging bubbles from the middle to the four sides to reduce the generation of bubbles. However, using the above method, on the one hand, the glass cover is easy to get dirty or even scratched, and on the other hand, the manual pressure is easy to be too large, which can easily cause damage to the glass cover, and the production efficiency and effect are not good.

[0029] See also Figure 1 The embodiment of the utility model provides a film sticking fixture, including: a limiting fixture 100, a sensor device 200 and a pressing and sticking device 300;

[0030] The limiting fixture 100 includes a pressing hole 110 and a limiting groove 120. The limiting groove 120 is used to fix the diaphragm 400 and the cover plate 500. When the film is attached, the cover plate 500 is arranged above the diaphragm 400.

[0031] The sensor device 200 is disposed in the limiting groove 120 and is used to detect whether the cover plate 500 is placed in the diaphragm 400 fixture;

[0032] The pressing and attaching device 300 is arranged below the pressing hole 110 and is electrically connected to the sensor device 200. After detecting that the cover plate 500 is placed in the limiting clamp 100, it passes through the pressing hole 110 and lifts up the diaphragm 400, thereby exhausting the air between the diaphragm 400 and the cover plate 500 to complete the film attachment.

[0033] The film sticking fixture of the utility model has a limiting clamp that fixes the diaphragm and the cover plate during the film sticking process. When the sensor device detects that the cover plate is placed in the diaphragm fixture, the pressing and attaching device is activated to allow the pressing and attaching device to pass through the pressing hole and lift up the diaphragm, thereby exhausting the air between the diaphragm and the cover plate to complete the film sticking, thereby realizing the alignment and film sticking of the cover plate without manual operation, solving the problems of stains, scratches and even damage to the cover plate that are prone to occur during manual operation, which not only improves production efficiency but also ensures production quality.

[0034] As a preferred embodiment of the present invention, the sensing device 200 is an infrared sensor. The infrared sensor can be set at the bottom or side wall of the limit groove. Since the film is transparent, during the film pasting process, even if the film is placed in the limit groove first, the infrared sensor will only sense the cover plate that is placed later and then start the film pasting process.

[0035] As a preferred embodiment of the present invention, the sensing device 200 is a weight sensor. The weight sensor can be set at the bottom of the limit groove. Since the diaphragm is very light, the sensing weight parameter of the weight sensor will be set to be greater than the weight of the diaphragm before it can be recognized. Therefore, during the film pasting process, although the diaphragm is placed in the limit groove first, the film pasting process will only start when the cover plate placed later is sensed.

[0036] As a preferred embodiment of the present invention, please refer to Figure 2 The side wall of the limiting groove 120 is provided with four retractable buckles 130, and the retractable buckles 130 are used to extend after detecting that the cover plate 500 is placed in the limiting fixture 100, so as to fix the cover plate 500, so that the cover plate 500 is not lifted up by the pressing attachment device 300 during the film application process. After the film application is completed, the retractable buckles 130 will be retracted to the inside of the side wall of the limiting groove 120.

[0037] As a preferred embodiment of the utility model, the pressing and attaching device 300 is an airbag, and the central axis positions of the airbag, the diaphragm 400 and the cover plate 500 are in a straight line in the vertical direction. The airbag is preferably conical or semicircular. After the film application process is started, the airbag begins to inflate, and during the inflation process, the diaphragm is lifted from the center to the surface of the cover plate, and as the airbag slowly increases, it transitions from the middle to the surroundings, thereby eliminating the bubbles between the diaphragm and the cover plate, and completing the film application. After the film application is completed, the airbag is deflated and restored to its initial state.

[0038] As a preferred embodiment of the present invention, the pressing and attaching device 300 may also include a conical or semicircular polyurethane foam pressing soft hammer and a telescopic bracket;

[0039] The central axis positions of the polyurethane foam pressing soft hammer, the diaphragm 400 and the cover plate 500 are in a straight line in the vertical direction;

[0040] After detecting that the cover plate 500 is placed in the limiting fixture 100, the telescopic bracket drives the polyurethane foam pressing hammer to rise to complete the film pasting.

[0041] After the film application process is started, the telescopic bracket drives the polyurethane foam pressing hammer to rise, and during the rising process, the diaphragm will be lifted from the middle to the surface of the cover plate. In addition, since the hammer is conical, as the hammer continues to rise, the contact area between the hammer and the diaphragm will gradually increase, and will transition from the center to the surroundings, thereby eliminating the bubbles between the diaphragm and the cover plate, and completing the film application. After the film application is completed, the airbag is deflated and restored to the initial state.

[0042] As a preferred embodiment of the utility model, a suction cup is further included, and the suction cup is used to put the diaphragm 400 or the cover plate 500 into the limiting groove 120. This avoids dirt and damage to the diaphragm or the cover plate caused by the operation of the staff, and saves labor costs.

[0043] As a preferred embodiment of the present invention, please refer to Figure 2 The limiting groove 120 is a circular groove formed by four limiting buckles 140. The telescopic buckles 130 can be arranged on the limiting buckles 140 in a one-to-one correspondence.

[0044] As a preferred embodiment of the present invention, the limiting clamp 100 further includes a buffer pad, which is arranged at the bottom of the limiting groove 120. This can prevent the cover plate from being damaged when being fixed in the limiting groove.

[0045] As a preferred embodiment of the present invention, the size of the pressing hole 110 is greater than or equal to the visible area of ​​the cover plate 500. This is beneficial to the integrity of the film. The specific shapes of the pressing hole and the cover plate are not limited.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
