[0002] During the touch screen production process, the bonding is mainly done by using water glue or optical glue to completely glue the display panel, touch screen, and protective glass together without gaps. The water glue process has gradually become a popular process due to its advantages such as high light transmittance, good bonding strength, and small curing shrinkage. However, as a liquid object, water glue has a certain gas solubility and is prone to bubbles. In addition, there may be local gaps during the leveling process of water glue. Therefore, it is necessary to check the produced touch screen products, check out defective products and recycle them. After confirming that there are no gaps or bubbles, the next step of UV curing can be carried out to improve the product yield.

[0003] Therefore, there is a touch screen bubble detection device with patent number CN218674691U, but the device has the following defects when used, such as: while manually driving the device, people are required to bend their heads and lean forward to the top of the touch screen to detect it, which can easily cause fatigue over a long period of time, thereby affecting processing efficiency and quality.

[0019] The following are examples and the attached Figure 1-3 , the technical solution of the present invention is further specifically described.

[0020] A touch screen lamination bubble detection device includes a base 1 with a frosted bottom structure:

[0021] The base 1 is provided with vertical plates 2 on both the front and rear sides, wherein an observation plate 3 is obliquely provided at one end of the base between the two sets of vertical plates 2, and a lampshade 4 is provided on one side of the top of the observation plate 3, and a lighting lamp 5 is provided in the lampshade 4, wherein the lampshade 4 is driven by an electric push rod 6, and the electric push rod 6 is installed on a horizontal plate 7 on the top of the two sets of vertical plates 2;

[0022] An L-shaped plate 8 is arranged on the top of the base 1 on the same side as the lampshade 4, wherein the bent end of the L-shaped plate 8 is arranged on the same side as the observation plate 3, and a rotating shaft 9 driven by a motor 10 is longitudinally arranged at the bent end of the L-shaped plate 8, and an arc groove 11 is also arranged on the top surface of the horizontal end of the L-shaped plate 8, wherein the arc groove 11 is connected to the vacuum pump through a corrugated hose 12, and a groove 13 that can accommodate the hose 12 is also arranged on the top of the base 1.

[0023] In this embodiment, the observation plate 3 is made of an acrylic plate, wherein the top end of the observation plate 3 is arranged on the same side as the lampshade 4. The acrylic plate has high light transmittance, which is convenient for the staff to detect the touch screen on the other side through it.

[0024] In this embodiment, the lampshade 4 and the vertical plate 2 are both made of a shading plate, wherein the opening of the lampshade 4 is inclined toward the L-shaped plate 8. The shading plate has good shading properties, preventing light from directly shining on the eyes of workers and causing damage to them.

[0025] like Figure 3 As shown, a limit rod 14 is arranged between the tops of the two sets of vertical plates 2, wherein the straight line formed by the limit rod 14 and the rotating shaft 9 is arranged parallel to the observation plate 3. The limit rod 14 limits the clockwise rotation range of the L-shaped plate 8.

[0026] In the present embodiment, the end of the horizontal end of the L-shaped plate 8 is provided with a U-shaped notch 15. It is convenient to pinch the top of the product on the L-shaped plate 8 through the U-shaped notch 15 to remove it.

[0027] The method of use of the present invention: Figure 2 As shown, the product is placed on the horizontal end of the L-shaped plate 8. At this time, the vacuum pump draws vacuum in the arc groove 11 through the hose 12 to adsorb and fix the product on the L-shaped plate 8 to prevent the product from sliding from its end surface during the subsequent rotation of the L-shaped plate 8 and affecting subsequent work. Then the motor 10 drives the L-shaped plate 8 to rotate clockwise through the rotating shaft 9, so that the L-shaped plate 8 and the product are in an inclined state so that people can inspect the product in the inclined state through the observation plate 3. In the above process, the inclination angle of the L-shaped plate 8 and the product above it can be adjusted according to requirements to meet the requirements;

[0028] At the same time, the light generated by the lighting lamp 5 in the lampshade 4 shines on the end face of the product, and the worker inspects the touch screen through the observation plate 3, making it easier for the worker to find out whether there are bubbles at the fitting part of the touch screen during inspection. The lampshade 4 can prevent the light from shining directly on the eyes of the worker, and the electric push rod 6 can drive the lampshade 4 and the lighting lamp 5 inside it to move up and down as required, so that it can illuminate different areas of the end face of the product, preventing some parts of the end face of the product from being far away from the lighting lamp 5, resulting in insufficient light and affecting the inspection work.

[0029] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
