Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt dust cleaning equipment, in particular to a display screen production line dust cleaning device. Background Art

[0002] Glass substrate refers to specially processed and manufactured glass, which is widely used in the electronics, optoelectronics, chemical, machinery and other industries. Its main function is to provide a carrier for some subsequent electronic precision components. After the production of the substrate glass is completed, it is cut on the assembly line according to actual needs. In this process, some glass debris will inevitably remain. Due to static electricity, the glass debris will not only adhere to the surface of the glass substrate, but also adhere to the rubber roller of the conveyor line, which will have a certain impact on the subsequent processing.

[0003] In the prior art, there is a patent application document with publication number CN 212711402U, entitled "Cleaning Device and Assembly Line". In the document, a flexible decontamination portion is provided to achieve rapid cleaning of the conveyor belt. The device is suitable for a rotary conveyor belt. However, if it is a conveyor roller, the device cannot achieve normal cleaning. The gentle decontamination is for the lower surface of the conveyor belt. After cleaning, if the conveyor belt is stained with water, it is still easy to adhere to a certain amount of dust particles. Therefore, the practicability is not strong. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a dust cleaning device for a display screen production line, which provides a cleaning roller whose lower end can always abut against the conveyor belt. Through the adhesion effect of the cleaning roller, the dust particles on the conveyor belt are adhered and cleaned, thereby reducing the interference of impurities on the substrate glass.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a dust cleaning device for a display production line, comprising a conveyor belt and a cleaning device located on the upper part of the conveyor belt; the cleaning device comprises a cleaning roller, a swing arm, a base plate and a fixed seat, one end of the cleaning roller is rotatably connected to the lower end of the swing arm, the upper end of the swing arm is hinged to the base plate through a pin shaft, a spring is clamped between the swing arm and the fixed seat, and the cleaning roller is always in contact with the upper end surface of the conveyor belt under the action of the spring; the outer end surface of the cleaning roller is covered with a sticky self-adhesive sticker.

[0006] Preferably, a moving device is also provided on the conveyor belt, and the moving device is used to drive the cleaning device to move along the length direction of the conveyor belt.

[0007] Preferably, the moving device includes a support seat, a transmission screw and a screw slider that is transmission-connected to the transmission screw, and a guide light bar for guiding is also provided between the two support seats; the fixed seat is fixedly connected to the screw slider.

[0008] Preferably, the fixing seat and the swing arm are both provided with a limiting boss, and the spring is sleeved on the limiting boss.

[0009] Preferably, the swing arm is provided with a plurality of adjustment holes, and the cleaning roller is detachably connected to the swing arm.

[0010] Preferably, the conveyor belt is any one of a roller conveyor belt and a rubber conveyor belt.

[0011] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0012] 1. Since a cleaning device is arranged on the upper part of the conveyor belt, the cleaning roller is driven to swing by the swing arm in the cleaning device. Under the action of the spring, the end face of the cleaning roller is used to abut against the conveyor belt, so that both the roller conveyor belt and the rubber pad conveyor belt can clean the dust, so the application range is wider. The end face of the cleaning roller is covered with sticky self-adhesive, and the cost is extremely low, especially for the cleaning effect of small granular impurities such as dust, which can avoid the situation that impurities appear in the middle of the substrate or carrier glass when in use, so the yield rate can be further improved.

[0013] 2. Due to the provision of a moving mechanism consisting of a transmission screw, in addition to passive rotation, the screw slider can actively move with the cleaning roller, thereby achieving a wider range of dust cleaning, including but not limited to conveyor belts, and can also clean the surface of long strips of carrier glass.

[0021] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a dust cleaning device 2 for a display production line, comprising a conveyor belt 1 and a cleaning device 2 located on the upper part of the conveyor belt 1; there are many types of conveyor belts 1, and the conveyor belt 1 used for conveying carrier glass or substrates is generally a roller conveyor belt 1 or a rubber pad conveyor belt 1, and the surface is covered with rubber as a buffer pad.

[0023] The cleaning device 2 includes a cleaning roller 21, a swing arm 22, a bottom plate 23 and a fixed seat 24. One end of the cleaning roller 21 is rotatably connected to the lower end of the swing arm 22, and the upper end of the swing arm 22 is hinged to the bottom plate 23 through a pin. A spring 25 is also clamped between the swing arm 22 and the fixed seat 24. Under the action of the spring 25, the cleaning roller 21 always abuts against the upper end surface of the conveyor belt 1; the outer end surface of the cleaning roller 21 is covered with a sticky adhesive. The cost of the adhesive is extremely low and is widely used in the cleaning of static electricity floating in clothing.
