Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure adsorption devices, in particular to a glass negative pressure adsorption device. Background Art

[0002] The glass negative pressure adsorption device is a device that uses the negative pressure principle to adsorb on the glass surface. This device generates negative pressure (i.e. pressure lower than atmospheric pressure) on the glass surface so that substances and liquids in the air are adsorbed to the glass surface. The adsorption device of the glass loading machine is mainly realized by a suction cup connected to the negative pressure device. When loading the glass, the forward motor stops when the detection switch next to the suction cup touches the glass, and the negative pressure device starts to draw a vacuum. The suction cup absorbs the glass under the action of the vacuum, and the flip-up film-taking mechanism carries the glass backward and separates it from the glass in front.

[0003] The patent with publication number CN221499810U discloses a negative pressure adsorption device for a glass loading and unloading machine, which includes a horizontal plate and a U-shaped hose. Vertical plates are respectively installed under both sides of the horizontal plate. Circular grooves are respectively opened on the vertical plates, and bearings are respectively installed in the circular grooves. An adjustment device is installed on the horizontal plate, and the adjustment device includes a double-headed threaded rod and a moving part.

[0004] In the above technology, the threaded sleeve drives the suction cup to move inward and outward, and is adjusted according to the length of the glass for adsorption. However, the distance between the table supporting the glass and the suction cup is also different, and the distance between the suction cup and the table cannot be adjusted, which reduces the use range of the adsorption device. The adsorption device is exposed to the external environment over a large area, and a large amount of dust is attached to the surface, which increases the labor intensity of cleaning. Therefore, innovation is made in this technology. Utility Model Content

[0025] Example 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4As shown, positioning holes are provided on both sides of the two contact blocks 10, and multiple recessed holes 14 are provided on both sides of the two adjustment frames 8.

[0027] Working principle: The glass negative pressure adsorption device is a device that uses the negative pressure principle to adsorb on the glass surface. This device generates negative pressure on the glass surface, that is, pressure lower than atmospheric pressure, so that substances and liquids in the air are adsorbed to the glass surface. The adsorption device of the glass loading machine is mainly realized by the suction cup 12 connected to the negative pressure device. When loading, the forward motor stops when the detection switch next to the suction cup 12 touches the glass, and the negative pressure device starts to draw a vacuum. The suction cup 12 sucks the glass under the action of the vacuum, and the flip-up mechanism carries the glass backward and separates it from the front glass. The contact block 10 can move up and down at one end of the adjusting rod 9, so the position height of the suction cup 12 can be adjusted, which increases the use range of the suction cup 12 for negative pressure adsorption of the glass and improves the ease of use of the adsorption device. Tear down the dustproof film 18 so that the two dustproof films 18 are respectively covered with the two sides of the negative pressure adsorption frame 1. One side surface of the dustproof film 18 is adhered with double-sided tape. Tear off the double-sided tape After that, the adhesive part can be bonded to the surface of the adjusting frame 8, and the two dust-proof films 18 can wrap the surrounding of the negative pressure adsorption frame 1, which can play a role in blocking dust, reducing the amount of dust adhering to the surface of the negative pressure adsorption frame 1 and the suction cup 12, and also reducing the number of times the staff cleans. After starting the servo motor 3, the two bonding blocks 5 can move at one end of the bidirectional threaded rod 4, so that the distance between the two suction cups 12 can be adjusted. As the bonding block 5 moves, the two reinforcement blocks 7 installed at the bottom thereof will also move at one end of the reinforcement rod 6. The support of the bottom of the bonding block 5 by the two reinforcement blocks 7 is increased, and the stability of the bonding block 5 during movement is increased. After the contact block 10 reaches the appropriate position height, one end of the two positioning strips 15 is sequentially embedded in the corresponding positioning holes and the inside of the concave hole 14. The three are threadedly connected, and the adjusting frame 8 and the contact block 10 can be installed, thereby ensuring the stability of the suction cup 12. One side of the silicone tube 13 is connected to the negative pressure pump.
