[0032] Example 1

[0033] To address the technical problems in the background art, the following auxiliary device for secondary drying of glass substrates is provided:

[0034] Combination Figure 1-7 As shown, the glass substrate secondary drying auxiliary device provided by the present invention includes a U-shaped base plate 1, and a substrate conveying mechanism is provided inside the U-shaped base plate 1. The substrate conveying mechanism is used to convey the glass substrate 17.

[0035] Two extension plates 4 are fixed on the top surface of the U-shaped base plate 1. Two rotating rods 6 are rotatably arranged between the two extension plates 4. Two pulleys 5 are fixedly sleeved on each rotating rod 6. A drive belt 7 is provided between two adjacent pulleys 5 and is connected by transmission through the drive belt 7.

The reciprocating adjustment mechanism 9 is used to drive the two drying auxiliary mechanisms to move relative to each other and oppositely to dry the glass substrate 17 in multiple positions.

[0037] The substrate conveying mechanism includes two conveying roller shafts 16 and a first motor 2. Each conveying roller shaft 16 is rotatably mounted inside the U-shaped base plate 1, and several conveying rollers 18 are uniformly fixedly mounted on each conveying roller shaft 16.

The first motor 2 is fixedly mounted on one side of the U-shaped base plate 1, and the power output end of the first motor 2 is fixedly connected to the corresponding conveying roller shaft 16.

[0038] The drying auxiliary mechanism includes a fixed slide rail 12 and a telescopic tube 8. The fixed slide rail 12 is fixedly connected to the extension plate 4. A fixing block 10 is fixedly provided on one side of the fixed slide rail 12. The side of the fixing block 10 away from the fixed slide rail 12 is fixedly connected to the drive belt 7.

[0040] In practical use, the glass substrate 17 to be dried for the second time is transported to several conveyor belts 3 through the drying and conveying equipment of the previous station.

[0041] Substrate conveying: Start the first motor 2. Under the power output of the first motor 2, drive the conveyor roller 16 on the left side and several conveyor rollers 18 on the conveyor roller 16 to rotate synchronously, thereby driving several conveyor belts 3 to drive synchronously. Under the drive of the conveyor belts 3, drive the conveyor roller 16 on the right side and several conveyor rollers 18 on the conveyor roller 16 to rotate synchronously. In this way, it is convenient to convey the glass substrate 17 to be dried for the second time to the bottom of the two air knives 14, so as to carry out secondary drying in the later stage and improve the processing quality of the glass substrate 17.

[0042] Secondary drying: By starting the hot air blower, hot air is delivered into the telescopic tube 8 and the air knife 14, and then air is discharged through several air outlets 15 on each air knife 14. This facilitates the secondary drying of the undried areas of the glass substrate 17.

[0043] Example 2

[0044] like Figure 1-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0045] The reciprocating adjustment mechanism 9 includes a second motor 97 and a rotating shaft 94. The second motor 97 is fixedly mounted on the U-shaped base plate 1. A turntable 98 is fixedly mounted on the power output end of the second motor 97. A connecting rod 99 is provided below the turntable 98. One end of the connecting rod 99 is rotatably connected to the U-shaped base plate 1. A reciprocating swing plate 95 is fixedly mounted on the other end of the connecting rod 99. The reciprocating swing plate 95 cooperates with the turntable 98.

[0046] The rotating shaft 94 is rotatably connected to the extension plate 4 located in front. The rotating shaft 94 and the corresponding rotating rod 6 are both fixedly fitted with synchronous pulleys 91. A synchronous belt 92 is provided between the two synchronous pulleys 91 and is connected by transmission through the synchronous belt 92. The rotating rod 6 extends through to the outside of the extension plate 4 located in front. A reciprocating gear 93 is fixedly provided at the end of the rotating shaft 94 away from the extension plate 4 located in front. A reciprocating engagement assembly 96 is provided between the reciprocating gear 93 and the extension plate 4 located in front. The reciprocating engagement assembly 96 engages with the reciprocating swing plate 95.

[0047] The reciprocating assembly 96 includes a fixed plate 961. One side of the fixed plate 961 is fixedly connected to the extension plate 4 located in front. A U-shaped slide plate 962 is slidably provided on the other side of the fixed plate 961. A rack plate 963 is fixedly provided on the side of the U-shaped slide plate 962 away from the fixed plate 961. The rack plate 963 is meshed with the reciprocating gear 93.

[0048] A first elliptical sliding hole is provided on one side of the rack plate 963, and a second elliptical sliding hole is provided below the first elliptical sliding hole. Both the first elliptical sliding hole and the second elliptical sliding hole are opened through the reciprocating swing plate 95.

[0049] In practical use, based on Embodiment 1, when it is necessary to further enhance the practicality of the device and facilitate multi-location drying of the glass substrate 17, the operation is as follows:

[0050] Secondary drying adjustment: Start the second motor 97. Under the power output of the second motor 97, drive the turntable 98 and the eccentric pin to rotate, which in turn drives the reciprocating swing plate 95 to swing left and right, thereby driving the connecting pin to move left and right. This facilitates the left and right reciprocating movement of the rack plate 963 and the U-shaped slide plate 962. At the same time, under the meshing operation, drive the reciprocating gear 93 to rotate, which in turn drives the rotating shaft 94 and the synchronous pulley 91 on the left to rotate synchronously, thereby driving the synchronous belt 92 to drive the transmission. Under the transmission of the synchronous belt 92, drive the synchronous pulley 91 on the right, the rotating rod 6 and the two pulleys 5 on the rotating rod 6 to rotate synchronously, which in turn drives the two drive belts 7 to drive the transmission. Under the transmission of the drive belts 7, drive the rotating rod 6 on the left and the two pulleys 5 on the rotating rod 6 to rotate synchronously. (The fixed block 10 at the front and the fixed block 10 at the rear are arranged vertically and vertically, see [reference]). Figure 5 This facilitates the relative and opposite movement of the two Z-shaped plates 13, which in turn facilitates the movement of the two air knives 14. This allows for multi-position drying of the glass substrate 17 to be dried in the later stages by moving the air knives 14, thereby increasing its practicality.
