[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a motor, brush bristles, and an air outlet box, utilizes the motor to drive the brush bristles to rotate. Since the brush bristles are in contact with the conveyor belt in the conveyor, the rotating brush bristles can clean the debris on the surface of the conveyor belt. At the same time, an external air source enters the air outlet box and acts on the brush bristles through the air outlet pipe, which can blow away the debris adhering to the brush bristles, preventing the debris from always adhering to the conveyor belt. This solves the problem in the prior art that the conveyor belt is easily contaminated with debris, affecting the cleanliness of the subsequent transport of glass substrates.

[0016] 2. This utility model, by setting up a delivery pump, a dispensing box, and a coating assembly, allows the glass substrate to be transported by the conveyor belt on the conveyor during use. During transport, the delivery pump operates, causing the liquid in the liquid tank to pass sequentially through the liquid pipe, the dispensing box, the liquid outlet, the rotating pipe, the hollow disc, and the connecting pipe into the mounting box, and then through the perforated coating brush. At this time, the rotating coating brush moves along the surface of the glass substrate to coat the liquid. Using the above method for coating the liquid not only ensures good uniformity of the liquid coating but also avoids liquid splashing, solving the problems of poor uniformity and splashing of the liquid after it acts on the glass substrate in the prior art, which leads to inconvenience in use.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the first embodiment of the present invention. This embodiment provides an automatic coating device for surface treatment of glass substrates, including a cleaning mechanism 1. The cleaning mechanism 1 includes a liquid tank 104. The liquid is located on the lower side inside the liquid tank 104. A transparent window is also fixed on the side wall of the liquid for viewing the liquid volume. A motor 108a is fixed on the rear side of the left wall of the liquid tank 104. A rotating roller 101 is fixed on the power output shaft of the motor 108a. Brushes 101a are fixed on the outside of the rotating roller 101. The rotating roller 101 is driven to rotate by the motor 108a, so that the brushes 101a rotate to brush away the debris on the surface of the conveyor belt. A conveying pump 107 is provided on the lower wall inside the liquid tank 104 for conveying the liquid. An air outlet box 102 fixed to the liquid tank 104 is provided in front of the rotating roller 101. The air outlet box 102 is connected to an external air source through a pipe. The external air source can blow away the debris adhering to the brushes 101a by blowing the brushes 101a.

[0031] Specifically, the interior of the liquid tank 104 is equipped with a filter plate 103 to prevent impurities from entering the lower part of the liquid tank 104 and contaminating the liquid. A mounting protrusion 104a, fixed to the liquid tank 104, is provided along the lower edge of the filter plate 103. A rectangular groove 104b is formed above the filter plate 103 corresponding to the front wall of the liquid tank 104. A door 105, rotatably connected to the liquid tank 104 via a hinge 105a, is located in front of the rectangular groove 104b. An L-shaped stop 106 is provided on the upper side of the door 105. The lower end of the L-shaped stop 106 near the door 105 has a chamfer. The upper side of the L-shaped stop 106 has a T-shaped rod 106a fixed to the liquid tank 104. The L-shaped stop 106 can rotate relative to the T-shaped rod 106a. With the above configuration, by operating the L-shaped stop 106 to rotate until it is disengaged from the door 105, the blocking effect on the door 105 is lost. Then the door 105 can be rotated to open the rectangular groove 104b. At this time, the filter plate 103 can be operated for maintenance or replacement.

[0032] The liquid outlet end of the delivery pump 107 is fixedly provided with a liquid pipe 107a, and the other end of the liquid pipe 107a is fixedly connected to the liquid distribution box 205. The delivery pump 107 can deliver the medicine to the interior of the liquid distribution box 205. The rear wall of the air outlet box 102 is provided with multiple air outlet holes 102a at equal intervals. The external air source passes through the air outlet holes 102a and acts on the bristles 101a to blow away the debris adhering to the bristles 101a.

[0033] The operation process of this embodiment is as follows: When in use, the motor 108a is driven to rotate the rotating roller 101, thereby causing the brush bristles 101a to rotate. The rotating brush bristles 101a contact the conveyor belt and brush away the debris adhering to the conveyor belt. At the same time, an external air source supplies air to the air outlet box 102 through a pipe. The gas passes through the air outlet 102a and acts on the brush bristles 101a to blow away the debris adhering to the brush bristles 101a.

[0034] Example 2

[0035] Please see Figure 1 , Figure 6 , Figure 7 and Figure 8This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a coating mechanism 2 is provided inside the liquid tank 104. The coating mechanism 2 includes a conveyor 201 for conveying the glass substrate. The conveyor 201 is a belt conveyor 201, which will not be described in detail here. A dispensing box 205 is provided above the conveyor 201 for diverting the liquid and allowing it to enter multiple outlet heads 205a. Multiple coating components 206 are arranged from left to right between the dispensing box 205 and the conveyor 201. 6 includes a rotating tube 206a, a hollow disk 206b fixed at the lower end of the rotating tube 206a, and several mounting boxes 206f arranged in a circular array below the hollow disk 206b. A connecting tube 206e fixed to the hollow disk 206b is fixed on the upper wall of the mounting box 206f. A coating brush 206g is fixed to the lower side of the inside of the mounting box 206f by bolts. The liquid medicine entering the rotating tube 206a passes through the hollow disk 206b and the connecting tube 206e in sequence into the mounting box 206f, and then wets the coating brush 206g to coat the glass substrate with the liquid medicine.

[0036] Specifically, the outside of the liquid separator 205 is provided with a U-shaped frame 204 fixed to the liquid tank 104. A hydraulic cylinder 203 fixed to the U-shaped frame 204 is fixed at the middle position of the upper wall of the liquid separator 205 for driving the liquid separator 205 to move accordingly. Guide rods 205c are fixed on both the left and right sides of the upper wall of the liquid separator 205. A guide sleeve fixed to the U-shaped frame 204 is fitted to the outside of the guide rod 205c with a clearance. The cooperation between the guide sleeve and the guide rod 205c can keep the liquid separator 205 in a horizontal state and improve the stability of the liquid separator 205 during use.

[0037] The rotating tube 206a is provided with a U-shaped plate 205b fixed to the dispensing box 205. The rotating tube 206a is rotatably connected to the U-shaped plate 205b through a bearing. The top of the rotating tube 206a is provided with a liquid outlet 205a fixed to the dispensing box 205. The inner diameter of the liquid outlet 205a is smaller than the inner diameter of the rotating tube 206a, so that when the medicine passes through the liquid outlet 205a, it will enter the rotating tube 206a.

[0038] A motor 202 is fixedly mounted on the lower wall of the separator 205. A gear 202a is fixedly mounted on the power output shaft of the motor 202. A gear 209 fixedly mounted on the outside of the corresponding rotating tube 206a is meshed with one side of the gear 202a. A pulley 208 is fixedly mounted on the outside of the multiple rotating tubes 206a. The pulleys 208 are connected to adjacent pulleys 208 at the same height via a belt 207. In the above configuration, the pulleys 208 are connected by a belt 207. When the motor 202 works, it drives the gear 202a to rotate, which in turn drives the gear 209 to work, thereby causing the corresponding rotating tube 206a to rotate. At this time, with the cooperation of the belt 207 and the pulleys 208, the multiple rotating tubes 206a rotate in the same clockwise direction, which ultimately drives the coating brush 206g to rotate and coat the glass substrate.

[0039] A partition 206j, fixed to the mounting box 206f, is provided above the coating brush 206g. The partition 206j has equidistant perforations 206i. The liquid coating solution entering the mounting box 206f passes through the perforations 206i and acts on the coating brush 206g, wetting it. In this state, the coating brush 206g rotates and contacts the surface of the glass substrate, thus coating the glass substrate with the liquid coating solution. A protruding block 206h is fixed to the upper wall of the mounting box 206f. The external sliding connection of 6h is a C-shaped plate 206d. The upper wall of the C-shaped plate 206d is threaded with a screw. The bottom of the screw abuts against the convex block 206h. By loosening the screw and adjusting the relative position of the convex block 206h and the corresponding C-shaped plate 206d, the coating diameter can be adjusted to achieve the purpose of adjusting the coating range. The upper wall of the C-shaped plate 206d is fixed with an installation strip 206c that is fixed to the hollow disk 206b and is used to connect the hollow disk 206b and the C-shaped plate 206d.

[0040] The operation process of this embodiment is as follows: When the conveyor 201 is working, the conveyor belt moves and drives the glass substrate to move. At this time, the motor 202 works and drives the gear 1 202a to rotate, which in turn drives the gear 2 209 to rotate and causes the rotating tube 206a to rotate. With the cooperation of the belt 207 and the pulley 208, multiple rotating tubes 206a rotate. When the rotating tube 206a rotates, it drives the hollow box, mounting strip 206c, C-shaped plate 206d, mounting box 206f, connecting pipe 206e and coating brush 206g to rotate. At the same time, under the operation of the delivery pump 107, the liquid medicine passes through the liquid pipe 107a, the liquid distribution box 205, the liquid outlet 205a, the rotating tube 206a, the hollow plate 206b, and the connecting pipe 206e in sequence and enters the mounting box 206f. Then it passes through the perforation 206i and wets the coating brush 206g. At this time, the coating brush 206g in the rotating state moves along the surface of the glass substrate and can coat the liquid medicine on the surface of the glass substrate.

[0041] It should be noted that the motor 108a, motor 202 and delivery pump 107 in this automatic coating device for surface treatment of glass substrates are all electrically connected to the controller via conductive wires. The controller is electrically connected to an external power supply via conductive wires. In addition, all electrical appliances in this automatic coating device for surface treatment of glass substrates are existing and can be purchased from the market or customized. No restrictions are placed on their models here.
