Description

Technical Field

[0001] The utility model relates to the field of glass spraying, in particular to an automatic glass spraying mechanism and automatic glass coating equipment. Background Art

[0002] Existing anti-fingerprint and anti-fouling coatings sprayed on glass surfaces can cause the following problems: 1. Airflow rebound or diffraction from the spray gun during spraying can cause overflow coating on the back of the product (the AF or AS anti-fingerprint nanocoating can flow onto the back of the product); 2. The sprayed AF or AS anti-fingerprint nanocoating can remain on the conveyor surface, where the glass flows onto the conveyor surface, contaminating the back of the glass. Subsequent processes to remove overflow coating require significant manpower and resources; overflow coating on the back of the AF or AS anti-fingerprint nanocoating can also result in poor adhesion of the TP lamination.

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0033] like Figure 2-5 As shown, this embodiment provides an automatic glass spraying mechanism 1, including a conveying device 11, a spraying device 12 and an anti-pollution device 13, the anti-pollution device 13 includes a discharge roller 1311, a receiving roller 1312, and an anti-pollution film material 1313. The anti-pollution film material 1313 wound on the discharge roller 1311 is drawn out from the discharge roller 1311, flows along the conveying surface of the conveying device 11, and is wound on the receiving roller 1312.

[0034] Further, see Figure 2 The conveying device 11 includes a conveying shaft 111, a conveyor belt 112, and a conveying motor 113. The conveyor belt 112 is sleeved on the conveying shaft 111, and the conveying motor 113 is used to drive the conveying shaft 111 to rotate. The anti-pollution film 1313 is attached to the surface of the conveyor belt 112. Of course, the conveyor belt 112 can also be omitted, and the glass can be conveyed directly by the conveying shaft 111. In this case, the anti-pollution film 1313 is attached to the upper edge of the conveying shaft 111. The conveying device 11 is used to convey glass products.

[0035] The spraying device 12 includes a spraying drive module 121 and a spray gun 122 . The spraying drive module 121 is used to drive the spray gun 122 to move above the conveying device 11 , and can spray (anti-fingerprint and anti-fouling) coating on the front of the glass conveyed by the conveying device 11 .

[0036] In this embodiment, the anti-pollution film 1313 can be made of paper or film. At the same time, the width of the anti-pollution film 1313 should be greater than or equal to the width of the glass to ensure that the anti-pollution film 1313 can completely cover the back of the glass when it is attached to the conveyor belt 112.

[0037] During conveying on conveyor belt 112, the unwinding roller 1311 unwinds the glass and cooperates with the receiving roller 1312 to receive it, allowing the anti-pollution film 1313 to adhere to the conveying surface of conveyor belt 112 and be rolled for transport. While conveyor belt 112 is conveying the glass, the glass rests on the anti-pollution film 1313, effectively protecting the back of the glass. Thus, when the spraying device 12 sprays the glass, the AF coating sprayed from the spray gun 122 is applied to both the glass surface and the anti-pollution film 1313, preventing contamination of the conveyor belt 112 and, consequently, the back of the glass. This prevents over-plating on the back of the glass, saving labor and resources required for over-plating removal, and ensuring a secure bond between the back of the glass and the TP. This facilitates fully automated coating processes (cleaning - plasma cleaning - spraying - baking - product back plasma cleaning - cleaning - laminating and packaging).

[0038] Further, see Figure 3-5The anti-pollution device 13 further includes a receiving motor 1314, which is used to drive the receiving roller 1312 to rotate. After the receiving motor 1314 is turned on, the receiving roller 1312 begins to receive the material, thereby driving the unloading roller 1311 to start unloading the material, and the anti-pollution film material 1313 begins to be transported along the conveying surface of the conveyor belt 112.

[0039] Further, see Figure 3-5 The anti-pollution device 13 further includes a (magnetic powder) clutch 1321, through which the receiving motor 1314 is connected to the receiving drum 1312. The clutch 1321 can control the output torque of the receiving motor 1314, thereby adjusting the rotational torque of the receiving drum 1312, and further adjusting the conveying tension of the anti-pollution film material 1313, thereby ensuring that the anti-pollution film material 1313 is flat.

[0040] Further, see Figure 3-5 The anti-pollution device 13 also includes a discharge tension roller 1322 and a discharge tension sensor 1323. The discharge tension roller 1322 is connected to the detection end of the discharge tension sensor 1323 through a bearing seat. After the anti-pollution film material 1313 is drawn out from the discharge roller 1311, it bypasses the discharge tension roller 1322 and then flows along the conveying surface of the conveying device 11. The clutch 1321 works according to the detection information of the discharge tension sensor 1323.

[0041] In this embodiment, a material unloading tension sensor 1323 is provided at both ends of the material unloading tension roller 1322. The material unloading tension sensor 1323 not only supports the material unloading tension roller 1322, but also can detect the force condition of the material unloading tension roller 1322. When it is detected that the tension of the material unloading tension roller 1322 is too large, the detection information is fed back to the material receiving control system. The material receiving control system promptly adjusts the torque of the clutch 1321 to reduce it, thereby reducing the tension of the material unloading tension roller 1322 and preventing the anti-pollution film material 1313 from breaking.

[0042] Further, see Figure 3-5 The anti-pollution device 13 further includes a (magnetic powder) brake 1331, which is in transmission connection with the unloading roller 1311. The brake 1331 can control the rotational torque of the unloading roller 1311, thereby adjusting the conveying tension of the anti-pollution film material 1313 to ensure that the anti-pollution film material 1313 is flat.

[0043] Further, see Figure 3-5The anti-pollution device 13 also includes a receiving tension roller 1332 and a receiving tension sensor 1333. The receiving tension roller 1332 is connected to the detection end of the receiving tension sensor 1333 through a bearing seat. After the anti-pollution film material 1313 flows along the conveying surface of the conveying device 11, it bypasses the receiving tension roller 1332 and is then wound onto the receiving drum 1312. The brake 1331 works according to the detection information of the receiving tension sensor 1333.

[0044] In this embodiment, a receiving tension sensor 1333 is provided at both ends of the receiving tension roller 1332. The receiving tension sensor 1333 not only supports the receiving tension roller 1332, but also can detect the force condition of the receiving tension roller 1332. When it is detected that the tension of the receiving tension roller 1332 is too small, the detection information is fed back to the material discharge control system. The material discharge control system promptly adjusts the torque of the brake 1331 to increase, thereby increasing the tension of the receiving tension roller 1332 to prevent the anti-pollution film material 1313 from wrinkling.

[0045] Further, see Figure 3-5 The anti-pollution device 13 also includes a discharge slide 1341, a discharge correction drive module 1342 and a discharge correction sensor 1343. The discharge roller 1311 can be slidably set on the discharge slide 1341. The discharge correction sensor 1343 is set in the area of the anti-pollution film material 1313 located between the discharge roller 1311 and the conveying device 11. The discharge correction drive module 1342 is used to drive the discharge roller 1311 to slide along the discharge slide 1341 according to the detection information of the discharge correction sensor 1343.

[0046] In this embodiment, the unloading slide 1341 extends perpendicular to the conveying direction of the conveyor 11. The unloading correction sensor 1343 includes a transmitter and a receiver, which are respectively located on the front and back sides of the anti-pollution film 1313. The transmitter sends a light signal to the receiver. Whether the light signal is blocked by the anti-pollution film 1313 forms the connection or interruption of the light signal of the unloading correction sensor 1343, and feeds back to the unloading correction system, thereby controlling the unloading correction drive module 1342 to drive the unloading roller 1311 to slide along the unloading slide 1341, thereby correcting the position of the unloading roller 1311.

[0047] Further, see Figure 3-5The anti-pollution device 13 also includes a material receiving slide 1351, a material receiving deflection correction drive module 1352 and a material receiving deflection correction sensor 1353. The material receiving roller 1312 can be slidably set on the material receiving slide 1351. The material receiving deflection correction sensor 1353 is set in the area of the anti-pollution film material 1313 located between the material receiving roller 1312 and the conveying device 11. The material receiving deflection correction drive module 1352 is used to drive the material receiving roller 1312 to slide along the material receiving slide 1351 according to the detection information of the material receiving deflection correction sensor 1353.

[0048] In this embodiment, the receiving slide 1351 extends perpendicular to the conveying direction of the conveying device 11. The receiving correction sensor 1353 includes a transmitter and a receiver, which are respectively located on the front and back sides of the anti-pollution film 1313. The transmitter sends a light signal to the receiver. Whether the light signal is blocked by the anti-pollution film 1313 forms the connection or interruption of the light signal of the receiving correction sensor 1353, and feeds back to the receiving correction system, thereby controlling the receiving correction drive module 1352 to drive the receiving roller 1312 to slide along the receiving slide 1351, thereby correcting the position of the receiving roller 1312.

Before glass spraying, the automatic glass cleaning mechanism 2 is first used to perform plasma cleaning on the glass to ensure the spraying effect.
