Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

After the device for conveying the glass plate adheres to foreign matters suspended in the air, the conveying friction force and conveying displacement of the substrate glass easily generate micro scratches on the surface of the glass, and the production and processing quality of the substrate glass is greatly influenced.

In order to overcome the above technical problems, the following technical solutions are provided.

Referring to fig. 1, the present invention provides a transmission unit. Comprises a driving wheel 1 coupled with a power device or self-driven, wherein the driving wheel 1 drives a driven wheel 3 to rotate through a transmission line 2. It should be noted that in this embodiment, the driven wheel 3 may be a single rotating wheel, or may be a row of rotating wheels formed by a plurality of coaxial rotating wheels. The transmission strip 2 in this scheme plays two kinds of effects, and one of them plays drive wheel 1 to the transmission effect from driving wheel 3, and its top surface that second transmission strip 2 plays the effect of bearing glass board. In order to support the above-mentioned structural components, one or more corresponding support frames 4 are provided. The support frame 4 can be an aluminum alloy member or a plastic steel member. It should be noted, however, that the structure of the support frame 4 does not affect the normal movement of the drive belt 2. Meanwhile, the vibration amplitude of the surface of the brush is large in the working state, accumulated hardened pollutants are not easy to form, and friction damage to the surface of the glass plate is effectively avoided. In order to further reduce the pollutants attached to the surface of the brush, a dust removing plate can be arranged on the support frame 4.

As shown in fig. 1 to 2, the driven wheels 3 can be arranged in various rows, and in principle, only the actual requirement of the glass plate needs to be met. This solution provides some alternative configurations. Firstly, the transmission strip 2 is stretched and tightened by the driving wheel 1 and the driven wheel 3 into an isosceles triangle with the vertex angle positioned below. The driven wheels 3 are two in number and are respectively positioned at two ends of the bottom edge of the isosceles triangle. The number of the driving wheels 1 is one, and the driving wheels are positioned at the top corners of the isosceles triangle. In this state, the transmission strip 2 at the bottom edge position of the upper part of the isosceles triangle plays a role in transmitting the glass plate. The driven wheels 3 at two ends of the row indirectly support the glass plate. And secondly, four driven wheels 3 can be arranged, the driving axes of the driven wheels are positioned in the same plane, and part of the transmission bars 2 are stretched and supported into a plane. All four driven wheels 3 can play an indirect supporting role for the glass plate. The stress uniformity of the glass plate in the transmission process is improved, and the glass plate is prevented from being broken due to nonuniform stress.

As shown in fig. 3, in order to avoid the driving wheel 1 having the driving rod 2 disengaged therefrom, a retaining ring 11 may be disposed at the circumferential outer edge of the driving wheel 1, and the two retaining rings 11 sandwich the driving rod 2. Dense brushes are laid on the outer surface of the transmission strip 2, and the brushes support the glass plate in a transmitted state, so that the friction between pollutants accumulated on the surface of the transmission strip 2 and the surface of the glass plate is avoided.

Referring to fig. 4, the present invention further provides a transmission belt, which is formed by sequentially connecting a plurality of the transmission units, and the transmission directions and the transmission speeds of the transmission units need to be kept consistent. For smooth conveyance of the glass sheet, the partial drive bars 2 serving as a conveyance means form a plane. In the production process of liquid crystal glass, a large-size glass substrate which is thin and very fragile, and a part of transmission strips 2 which need to play a transmission role form a plane, so that the glass plate is effectively prevented from being broken due to insufficient bearing force. Since the driving wheel 1 is often rigidly connected to the power source, the amplitude and frequency of the chattering vibrations are high, which may adversely affect the glass sheet, and therefore it is necessary to maintain the circumferential edge apex of the driving wheel 1 not higher than the circumferential edge apex of the driven wheel 3. The transmission belts after the sequential connection and assembly can transmit the glass plates according to the preset direction.

Referring to fig. 5, the utility model further provides a protective transmission device including the transmission belt. In order to avoid that contaminated air from the outside comes into contact with the conveyor belt 2, a sealing housing 5 is arranged outside the conveyor belt. However, suspended particulate contaminants may also be present inside the sealed housing 5, and therefore the interior of the sealed housing 5 is also in communication with a high pressure air filter 6. The high-pressure air filter 6 filters particles in the outside air and outputs high-purity air into the sealed housing 5. Due to the limitations of the processing technology and the specific operating conditions, the sealed housing 5 still has a channel communicated with the outside, and the high-pressure air filter 6 is required to continuously inject high-purity air into the sealed housing 5 to maintain the positive air pressure inside the sealed housing relative to the outside. Can keep the contaminated air of outside can not contact with transmission strip 2, just can not form the pollutant of accumulation on transmission strip 2 surface or brush surface yet, effectively solve the problem of the little fish tail of glass surface in the transmission course.

Referring to fig. 6, the sealed enclosure 5 is divided into a first working section 51 and a second working section 52, the height of the inner cavity of the second working section is greater than that of the first working section 51, the high-pressure air filter 6 is communicated with the inner cavity of the second working section 52, so that the diffusion efficiency of high-purity air pumped into the inner cavity of the sealed enclosure 5 by the high-pressure air filter 6 is improved, the concentration of pollutants in the sealed enclosure 5 is further reduced, and the problem of micro scratches on the surface of glass during transmission is effectively solved.

As a complete application of the scheme, please refer to fig. 1 to 6, a sealing housing 5 is arranged outside the conveyor belt, an inner cavity of the sealing housing 5 is further communicated with a high-pressure air filter 6, the high-pressure air filter 6 filters particles in the outside air, and high-purity air is output into the sealing housing 5. The transmission strip 2 is stretched and tightened by the driving wheel 1 and the driven wheel 3 into an isosceles triangle with the vertex angle positioned below. The driven wheels 3 are two in number and are respectively positioned at two ends of the bottom edge of the isosceles triangle. The number of the driving wheels 1 is one, and the driving wheels are positioned at the top corners of the isosceles triangle. In order to support the above-mentioned structural components, one or more corresponding support frames 4 are provided. In order to avoid the driving wheel 1 from disengaging from the driving strip 2, the driving wheel 1 may be provided with a retaining ring 11 at the circumferential outer edge, and the two retaining rings 11 sandwich the driving strip 2. Dense brushes are laid on the outer surface of the transmission strip 2, and the brushes support the glass plate in a transmitted state, so that the friction between pollutants accumulated on the surface of the transmission strip 2 and the surface of the glass plate is avoided. The sealed shell 5 is divided into a first working section 51 and a second working section 52, the height of the inner cavity of the two working sections is larger than that of the inner cavity of the first working section 51, the high-pressure air filter 6 is communicated with the inner cavity of the second working section 52, and the filtered clean gas is injected into the sealed shell 5. The problem of micro scratch on the surface of glass in the transmission process is effectively solved by avoiding the contact of the transmitted plate and the surface pollutants of the transmission belt.
