Description

Automatic cleaning device for conveying trolley on liquid crystal glass substrate production line

technical field

The utility model belongs to the field of liquid crystal glass production and manufacture, and relates to a conveying device used on a liquid crystal glass substrate production line, that is, a supporting automatic cleaning device for a conveying trolley.

Background technique

Due to the increasing popularity of liquid crystal displays, the demand for liquid crystal glass substrates in the liquid crystal display industry is also increasing, so higher requirements are put forward for the production capacity and degree of automation of automated production lines. In the lead-in process of the liquid crystal glass substrate production line in the initial stage of commissioning, after cutting by the cross-cutting machine, the robot loads it onto the conveying trolley on the conveyor belt, and clamps the glass edge with the help of the cutting board in the claw mechanism of the conveying trolley, and drives and conveys the liquid crystal glass substrate. During the transportation process, some glass with large warpage, cracks and other defects should be directly smashed and thrown into the cullet chute. Since the cutting board is made of silicone rubber, the glass substrate is still in the high temperature stage, so it will remain on the cutting board. Some broken glass slag and dust will cause damage to the glass substrate during the next delivery of the glass substrate, affecting the quality of the glass substrate.

Contents of the invention

In order to solve the problem of ensuring the cleanliness of the chopping boards on the trolley and thus the quality of the glass substrate, an automatic cleaning device for the conveying trolley on the liquid crystal glass substrate production line is designed to clean the chopping boards on the trolley by rotating the roller brush at high speed. Two chopping boards sandwiched with glass effectively ensure the quality of the glass substrate.

The technical scheme adopted by the utility model is: the automatic cleaning device for the conveying trolley on the liquid crystal glass substrate production line, the structure is fixed under the conveying trolley by means of the support seat, the key lies in: the structure includes: the base frame is limited by the bearing The roller brush on the roller brush and the roller brush rotation drive mechanism, the base frame has a vertical lifting degree of freedom by means of the lifting drive mechanism.

The beneficial effects of the utility model are: the device uses a roller brush to rotate at a high speed to clean the two cutting boards sandwiched with glass on the trolley, remove broken glass slag and dust, and add a garbage collection device to achieve the effect of cleaning and dust removal, effectively It ensures the smooth operation of the production line and makes the glass conveying link more orderly.

The utility model is described in detail below in conjunction with accompanying drawing.

Detailed ways

The automatic cleaning device for the conveying trolley on the liquid crystal glass substrate production line, the structure is fixed under the conveying trolley 2 by means of the support base 1, the important thing is: the structure includes: the roller brush 3 limited on the base frame 6 by means of bearings , and the roller brush rotation drive mechanism, the base frame 6 has a vertical lifting degree of freedom by means of the lifting drive mechanism. The device uses roller brush 3 high-speed rotation to clean the two cutting boards sandwiched with glass on the trolley, removes broken glass slag and dust, and adds a garbage collection device to achieve the effect of cleaning and dust removal, effectively ensuring the smooth operation of the production line Sex, make the glass conveying link more orderly.

The structure of the roller brush rotation driving mechanism includes: a motor 5 fixed on the base frame 6 , the main shaft of the motor 5 is connected with the roller brush 3 by means of a coupling 4 .

Directly below the roller brush 3 is also provided with a garbage collecting device 10 .

The described lifting drive mechanism is an air cylinder 11, and the end of the piston rod 7 in the air cylinder 11 is fixed with a pedestal pallet 12.

The base frame 6 has the structure of the vertical lifting degree of freedom by means of the lifting drive mechanism: the lower end surface of the base frame 6 is provided with a guide shaft 9, which forms a sliding fit with the fixed linear bearing 8 on the support base 1 .

The cylinder 11 is a three-rod cylinder.

In specific implementation, as shown in Figure 1, the three-rod cylinder is fixed on the support seat 10, the end of the piston rod 7 in the cylinder is fixed with the base frame supporting plate 12, and the guide shaft 9 is fixed on the lower end surface of the base frame 6 , the up and down movement of the base frame 6 is guided by the linear bearing 8 to ensure that the base frame 6 moves vertically to a straight line; the roller brush 3 is fixed on the base frame 6 through a bearing with seat, and the motor 5 is fixed on the On the base frame 6, the shaft coupling 4 is used to connect the roller brush 3 and the main shaft of the motor 5, and the motor 5 drives the roller brush 3 to rotate; the garbage collection device 10 is located directly below the roller brush 3 and is fixed on the base frame 6 On the top, it is connected with the suction pipe through the suction pipe.
