Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a degumming and feeding conveying line. Background Art

[0002] Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy and is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology.

[0003] In silicon wafer production technology, after the crystal rod is sliced, it is necessary to perform a degumming process on the sliced ​​crystal rod. The existing technology mostly uses roller conveyor lines such as plastic or rubber, and the sliced ​​material is placed in the degumming material tray at the unloading station of the slicer, and transported from the unloading station of the slicer to the loading station of the degumming machine. Then the degumming material tray at the loading station of the degumming machine is placed in the degumming machine together with the material for degumming. When the silicon wafer is degummed, it is taken out from the degumming rack by manual material removal, and then the empty degumming material tray is placed on the roller conveyor line, and the roller conveyor line is used to return it to the slicing unloading station;

[0004] The existing conveyor lines have a low degree of automation. Especially when multiple material trays are waiting on the conveyor line, the material trays are prone to collision, which reduces the service life of the material trays. At the same time, the feed end of the existing conveyor line has no safety structure, which often causes workers to be drawn into the conveyor line, causing certain life-threatening dangers.

[0005] Therefore, we propose a degumming feeding conveyor line to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a degumming feeding conveyor line, comprising: a frame 1, a main transfer chain 8 is rotatably arranged in the frame 1, a servo motor 7 is fixedly installed at the lower left end of the frame 1, the servo motor 7 drives the transmission chain 9, and the transmission chain 9 drives the main transfer chain 8;

[0027] The driving transmission chain 9 of the servo motor 7 drives the main transfer chain 8 to work and transfer the material tray;

[0028] A protective cover 10 covering the transmission chain 9 is provided on the side of the frame 1 to protect the transmission chain 9;

[0029] A material support in place sensor 2 is fixedly arranged at the left end of the frame 1, and a material feeding sensor 4 is installed at the right end of the frame 1;

[0030] When the tray enters the rack 1, the in-place status of the tray is sensed by the feed sensing device 4. When it is sensed that the tray has reached the specified position, the main transfer chain 8 works to transfer the tray to the other end. The tray in-place sensor 2 senses the in-place status and sends the in-place status to the upper control system. The upper control system drives the robot arm or other unloading equipment to transfer the tray on the main transfer chain 8, and at the same time, arranges the lower tray to enter the rack 1 in an orderly manner.

[0031] A guide structure 5 is fixedly installed on both sides above the frame 1. The guide structure 5 is mainly composed of a cylindrical guide rail. When the material tray moves with the main transfer chain 8, the guide structure 5 guides the material tray to prevent the material tray from deviating or even leaving the main transfer chain 8.

[0032] A front-end unpowered roller 6 is also installed at the right end of the frame 1. The front-end unpowered roller 6 is used to assist the material tray to slide into the top of the frame 1, making it more convenient and labor-saving for the material tray to enter the frame 1, while protecting the safety of personnel and preventing them from being drawn into the inside of the machine;

[0033] A spring check mechanism 3 is installed in the middle of the frame 1. The spring check mechanism 3 is mainly composed of a block and a spring. When the material tray slides through the spring check mechanism 3, the block is pressed to be level with the bottom surface of the material tray, and the spring is stretched. When the material tray slides out of the block, the spring resets to pull up the block, and the block prevents the material tray from moving back.

[0034] Working principle: The material tray is sent to the frame 1 through the front-end unpowered roller 6, which protects the safety of personnel and prevents them from being drawn into the machine. The material tray is set on the main transfer chain 8, and the servo motor 7 is started to drive the main transfer chain 8 to work, so as to realize the transfer of the material tray. In this process, the material tray position sensor 2 and the feed sensing device 4 cooperate to realize the sensing of the material tray position, provide the upper automation system with the material tray status information, and improve the automation operation of the material tray movement;

[0035] The spring check mechanism 3 prevents the material tray from moving back and colliding with the lower material tray, thereby increasing the service life of the material tray;

[0036] The guide structure 5 plays an auxiliary role in guiding, preventing the tray from deviating from the frame 1 and falling off during the transfer process.
