Description

Technical Field

[0001] This utility model relates to the field of glass production equipment technology, specifically to a five-in-one production line for photovoltaic glass. Background Technology

[0002] In the photovoltaic glass industry, deep processing production lines generally adopt a three-in-one production line method to match tempering furnaces for glass production. This is mainly achieved through two modes: traditional roller conveyor belts with intersecting roller conveyors or slab roller conveyors with three layers of intersecting roller conveyors.

[0003] As industry competition intensifies, to further increase per capita productivity and reduce unit production costs, only larger production lines can meet the demands for cost reduction and efficiency improvement, adapting to market development, such as the five-in-one production line. However, using the traditional roller conveyor + belt conveyor system, where each glass lifting and lowering requires waiting for the previous glass to leave, the slab-by-slab confluence cannot meet the capacity requirements of the 80m tempering furnace in the five-in-one line. While adopting a swaying roller conveyor + three-layer interconnection system can barely meet the production cycle requirements, it still has two drawbacks: First, to meet high-speed slab separation and confluence, the linear speed of the glass on the roller conveyor must be increased, estimated to reach over 110m / min, which will affect equipment stability and glass quality. Second, using a swaying roller conveyor requires adding a 5-meter-long swaying roller conveyor to each branch glass confluence to achieve high-speed and stable glass transport, significantly increasing the total line length by approximately 25 meters, thus limiting wiring within the existing factory building. Utility Model Content

[0004] In view of this, in order to solve the problems of the prior art, this utility model provides a five-in-one production line for photovoltaic glass.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A five-in-one production line for photovoltaic glass includes a main line and a first branch line, a second branch line, and a third branch line and a fourth branch line arranged in parallel on one side of the main line. The first branch line is located between the main line and the second branch line, and the third branch line is located between the main line and the fourth branch line. Connecting mechanisms are provided between the first branch line and the second branch line, between the second branch line and the main line, between the third branch line and the main line, and between the third branch line and the fourth branch line. Turning mechanisms are provided between the first branch line and the main line and between the third branch line and the main line. The turning mechanisms are used to transfer the photovoltaic glass located on the connecting mechanisms to the main line. The direction of movement of the photovoltaic glass on the connecting mechanisms is perpendicular to the direction of movement on the main line.

[0007] By installing connecting mechanisms between the first branch line and the main line and the second branch line, as well as between the third branch line and the main line and the fourth branch line, and by installing turning mechanisms between the first branch line and the main line and between the third branch line and the main line, photovoltaic glass transported on the second branch line can be transferred to the first branch line and then to the main line. At the same time, photovoltaic glass transported on the fourth branch line can be transferred to the third branch line and then to the main line. This allows photovoltaic glass from all four branch lines to be transferred to the main line and enter the tempering furnace together with the photovoltaic glass on the main line, significantly increasing the production cycle time, thereby effectively increasing production capacity and saving production costs.

[0008] According to a preferred embodiment of the present invention, the first branch and the second branch are of equal length, the third branch and the fourth branch are of equal length, and the first branch and the third branch are of different lengths.

[0009] According to a preferred embodiment of the present invention, the length of the first branch line is less than the length of the third branch line, the length of the third branch line is less than the length of the main line, and one end of each of the first, second, third, and fourth branch lines is flush with one end of the main line on the same side.

[0010] According to a preferred embodiment of the present invention, both the first branch line and the second branch line sequentially include a variable speed roller conveyor, a storage roller conveyor, a transition roller conveyor and an intersecting roller conveyor connected to each other, and the intersecting roller conveyor in both the first branch line and the second branch line is located at one end close to the connecting mechanism between the first branch line and the second branch line.

[0011] According to a preferred embodiment of the present invention, the third branch line and the fourth branch line each sequentially include a variable speed roller conveyor, a storage roller conveyor, a transition roller conveyor, a storage roller conveyor, a transition roller conveyor and an intersecting roller conveyor connected to each other, and the intersecting roller conveyor in the third branch line and the fourth branch line is located at one end close to the connecting mechanism between the third branch line and the fourth branch line.

[0012] According to a preferred embodiment of the present invention, the connecting mechanism is a transition roller conveyor. The two ends of the connecting mechanism located between the first branch line and the second branch line are respectively connected to one end of the cross-sectional roller conveyor on the first branch line and one end of the cross-sectional roller conveyor on the second branch line. The two ends of the connecting mechanism located between the third branch line and the fourth branch line are respectively connected to one end of the cross-sectional roller conveyor on the third branch line and one end of the cross-sectional roller conveyor on the fourth branch line.

[0013] According to a preferred embodiment of the present invention, the main line includes a confluence section and a sheet discharge section connected together. The confluence section is located at the front end of the sheet discharge section. One of the two steering mechanisms is located between the confluence section and the sheet discharge section. The confluence section includes a variable speed roller conveyor, a sheet storage roller conveyor and a plurality of transition roller conveyors. The other steering mechanism of the two steering mechanisms is located between two adjacent transition roller conveyors of the confluence section.

[0014] According to a preferred embodiment of the present invention, each of the steering mechanisms includes a hollow roller conveyor, a synchronous belt roller conveyor, a first shuttle device, and a second shuttle device. The hollow roller conveyor in the steering mechanism between the first branch line and the main line is located between two adjacent transition roller conveyors in the confluence section. The hollow roller conveyor in the steering mechanism between the third branch line and the main line is located between a transition roller conveyor near the sheet-laying section in the confluence section and the sheet-laying section. In some embodiments of the present invention, the first shuttle device and the second shuttle device do not interfere with each other. Both shuttle devices adopt a servo motor and a high-speed gear rack structure, and the shuttle speed can reach more than 100 meters / min. At the same time, the photovoltaic glass and the shuttle devices do not move relative to each other, which can avoid glass breakage and ensure glass quality.

[0015] According to a preferred embodiment of the present invention, one end of the synchronous belt roller conveyor is fixedly connected to one end of the hollow roller conveyor, the first shuttle device is connected to the second shuttle device, the hollow roller conveyor and the synchronous belt roller conveyor are installed on the first shuttle device and the second shuttle device, the first shuttle device is located directly below the hollow roller conveyor, and the second shuttle device is located directly below the synchronous belt roller conveyor.

[0016] According to a preferred embodiment of the present invention, the end of the synchronous belt roller in the steering mechanism that is away from the hollowed-out roller abuts against the end of the connecting mechanism that is away from the cross roller. The length direction of the roller of the connecting mechanism is perpendicular to the length direction of the synchronous belt roller, the length direction of the synchronous belt roller is parallel to the length direction of the hollowed-out roller, and the direction of movement of the photovoltaic glass on the roller of the steering mechanism is parallel to the direction of movement on the synchronous belt roller and perpendicular to the direction of movement on the hollowed-out roller.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model provides a five-in-one production line for photovoltaic glass. By setting connecting mechanisms between the first branch line and the main line, and between the second branch line and the third branch line, and between the third branch line and the main line and the fourth branch line, and by setting turning mechanisms between the first branch line and the main line, photovoltaic glass transported on the second branch line can be transferred to the first branch line and then to the main line. Simultaneously, photovoltaic glass transported on the fourth branch line can be transferred to the third branch line and then to the main line. This allows photovoltaic glass from all four branch lines to be transferred to the main line and enter the tempering furnace together with the photovoltaic glass on the main line. The production line layout is relatively short, with a total length of approximately 36.5m, only 7.5m longer than a conventional three-in-one production line. However, the production cycle time and capacity of the five-in-one production line are significantly increased, effectively saving production costs. Furthermore, the control method of this five-in-one production line is more flexible, allowing switching between four-in-one and three-in-one modes according to actual production needs, reducing unnecessary equipment operation and avoiding energy waste.

[0030] Specifically, the perforated roller conveyor 13 includes a frame, a full-roller assembly, a gear guard assembly, a conveying power assembly, and adjustable feet. The frame is connected to the adjustable feet and fixed to the ground with expansion bolts. The full-roller assembly, gear guard assembly, and conveying power assembly are all mounted on the frame.

The shuttle roller conveyor frame is connected to the shuttle hollow roller conveyor 13. The first and second belt single-line bodies are used to support and transport the photovoltaic glass 8. The steering mechanism 7 in this embodiment adopts the structure disclosed in the invention application with application number 2023110231571 and patent name "High-speed shuttle roller conveyor device". Further detailed structure will not be described here. In this embodiment, the first shuttle device and the second shuttle device do not interfere with each other. Both shuttle devices adopt servo motors and high-speed gear rack structures, and the shuttle speed can reach more than 100m / min, ensuring that the photovoltaic glass 8 does not move relative to the shuttle device during transmission, thus avoiding the breakage of the photovoltaic glass 8 and ensuring the quality of the photovoltaic glass 8.

That is, in this embodiment, the first photovoltaic glass 8 is conveyed to the full glue roller assembly through the previous process, the full glue roller assembly conveys the first photovoltaic glass 8 to the designated position, and the full glue roller assembly stops conveying; the first shuttle moving assembly is raised to detach the first photovoltaic glass 8 from the full glue roller assembly, and moves horizontally above the synchronous belt roller conveyor 14, and then lowers to place the photovoltaic glass 8 on the first belt single line and the second belt single line; the first belt single line and the second belt single line convey the first photovoltaic glass 8 to the next process; at the same time, the first shuttle moving assembly moves horizontally in the opposite direction; at the same time, the full glue roller assembly conveys the second photovoltaic glass 8 to the designated position, and the full glue roller assembly stops conveying. The second shuttle moving component lifts the second photovoltaic glass 8 to detach it from the full-glue roller assembly and moves horizontally above the synchronous belt roller conveyor 14. It then lowers to place the second photovoltaic glass 8 onto the first and second belt single-line bodies. The first and second belt single-line bodies transport the second photovoltaic glass 8 to the next process. Simultaneously, the first shuttle moving component moves horizontally in the opposite direction and stops, waiting for the third photovoltaic glass 8. The second shuttle moving component moves horizontally in the opposite direction to the initial position, completing the entire operation. This allows the photovoltaic glass 8 on the first branch line 2 and the third branch line 4 to converge onto the main line, effectively reducing the slicing pressure of the photovoltaic glass 8 on the main line.
