Abstract
The utility model relates to a kind of protection systems for preventing quartz boat from falling, including board, quartz boat, paddle, paddle support and quartz boat conveyer, the quartz boat to be placed on paddle；One end of the paddle is connect with paddle support, and the other end is free end；Further include photoelectric sensor, is set to the front end of the paddle free end；There is certain distance between the light beam and paddle lower surface of the photoelectric sensor sending；The photoelectric sensor and the intelligent link of quartz boat conveyer.The utility model to realize control that photoelectric sensor acts quartz boat conveyer, prevents paddle fracture quartz boat from falling according to the stress amount of offseting downward of paddle.
Description
Technical field
The utility model relates to solar battery sheet production equipments, specifically disclose a kind of protection system for preventing quartz boat from falling
System.
Background technique
Solar battery the characteristics of its high-efficiency cleaning to be widely accepted, and gradually substitution non-renewable energy resources become the mankind
The preferred energy.With the fast development of solar battery industry, industry competition is also increasingly fierce, is constantly reducing the same of cost
When, reducing unnecessary abnormal loss is also the important channel for improving production capacity and income, therefore improves manufacture of solar cells and set
Standby safety also becomes the task of top priority.
Diffusion production PN junction is the important link in manufacture of solar cells process.It is diffused using tubular type diffusion machine
Form PN junction.The Load System of tubular diffusion furnace is by cooler bin, paddle and paddle support, and conveyer belt system, (quartz boat transports dress to lift
Set), store (storage shelf), shuttle (quartz boat conveying device), vacuum WAND device and other related Control Systems form.
Diffusion furnace tube is vertically arranged, and each boiler tube is corresponding equipped with a paddle and paddle support.Diffusion needs boat carrying cell piece and send to furnace
Pipe is diffused program, and boat generally uses quartz material, and price is more expensive.Non-diffused cell piece is loaded into quartz boat when production
Interior, quartz boat is sent to diffusion furnace loading stage by shuttle, is sent on paddle by lift, then will be carried by the transmission of paddle
There is the quartz boat of cell piece to be sent into diffusion furnace tube and be diffused technique, after technique, paddle carrying quartz boat is sent to boiler tube
Outside, then by lift it is sent to store, waits blanking.Need to be operated manually lift in maintenance of equipment or other situations to pass
When dynamic quartz boat, due to misoperation, when quartz boat is on paddle, operation lift is downward, since the downward power of lift is larger,
Disconnected paddle is easily caused, the quartz boat being located on paddle is caused to fall, if the paddle being pressed down at this time is located at high-order, will cause vertical
The interior cell piece carried of paddle, the quartz boat on paddle and the quartz boat of lower end is crushed, and is not only caused any property loss, be will affect simultaneously
Production capacity, loss are serious.
Paddle carries quartz boat after boiler tube removal, and the quartz boat weight for being mounted with cell piece is larger, when on paddle, paddle meeting
Stress generates downwards certain offset, and the position for having paddle support is the head of paddle, and due to the effect of paddle support, offset is smaller,
Tail portion (front end free end) offset of paddle can be larger.Cause quartz boat on paddle when there is faulty operation or other abnormal conditions
When by other abnormal downward external force, the offset of paddle tail down can increase extremely, when stress can be led to when critical point greatly
Paddle is caused to be pressed down, quartz boat falls on paddle, causes very huge economic loss.
Utility model content
The goal of the invention of the utility model is: a kind of to solve the above problem effectively to be prevented by photoelectric sensor
The only protection system that quartz boat falls.
The technical solution adopted in the utility model is such that
A kind of protection system for preventing quartz boat from falling, including board, quartz boat, paddle, paddle support and quartz boat conveyer,
The quartz boat is placed on paddle；One end of the paddle is connect with paddle support, and the other end is free end；It further include photoelectric sensor,
It is set to the front end of the paddle free end；There is certain distance between the light beam and paddle lower surface of the photoelectric sensor sending；It is described
Photoelectric sensor and the intelligent link of quartz boat conveyer.
Further, the photoelectric sensor is connected and fixed on board side wall.
Further, the photoelectric sensor is reflector type photoelectric sensor or diffusion reflection pattern photoelectric sensor.
It further, further include warning device, with the photoelectric sensor intelligent link.
In conclusion due to the adoption of the above technical scheme, the beneficial effects of the utility model are:
Optical receiver can receive light in photoelectric sensor in without hindrance situation, but deviate centainly when paddle free end is downward
When amount, light can be blocked, and photoelectric sensor exports a switch control signal, and lift (quartz boat conveyer) is made to stop work
Make, and trigger warning device and issue alarm, operator can have found rapidly mistake or abnormal conditions, and take timely measure, and prevent
Only break paddle and quartz boat falls situation.
Detailed description of the invention
Fig. 1 is the system construction drawing of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of protection system for preventing quartz boat from falling, including board side wall 1, quartz boat 2, paddle 3, paddle support
4 and quartz boat conveyer, the quartz boat 2 be placed on paddle 3；One end of the paddle 3 is connect with paddle support 4, and the other end is freely
End；
It further include photoelectric sensor 5 and warning device, the photoelectric sensor is set to the front end of 3 free end of paddle,
It is connected and fixed on 1 side wall of board；There is certain distance between 3 lower surface of light beam and paddle that the photoelectric sensor 5 issues, the distance
Very little is determined according to the gryposis offset of paddle 3；The natural torsion that cell piece formation is placed in quartz boat 2 will not touch
Shine electric transducer 5, and is pressurized downwards from paddle 3, and gryposis degree is initially increased to fracture beaming limit, intermediate all to touch
Shine electric transducer 5；The photoelectric sensor 5 and quartz boat conveyer, warning device intelligent link, when paddle 3 occurs downwards
When certain exception offset, photoelectric sensor 5 does not receive light, issues a switch control signal, intelligentized control method quartz boat
Conveyer stopping movement and warning device alarm.
The photoelectric sensor 5 is reflector type photoelectric sensor or diffusion reflection pattern photoelectric sensor.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
