Description

Technical Field:

[0001] The present invention relates to the technical field of edge silicon material recycling and processing equipment, and particularly to an adhesive removing device for adhesive silicon materials. Background Art:

[0002] Monocrystalline silicon is the core basic material for photovoltaic crystalline silicon batteries and semiconductor devices. In the current production process, after the monocrystalline silicon rod is grown and formed by the Czochralski method, it needs to be segmented and cut according to the process size requirements of the downstream slicing process. However, during the cutting process according to the process length size, there will be short-section materials with small remaining sizes, and the monomer length thereof cannot meet the clamping and positioning requirements of the squaring machine; in order to ensure the continuous reuse of the short-section materials and the clamping and positioning process requirements, it is usually necessary to axially splice multiple short-section materials with an adhesive to form a process-available length, and then perform squaring and slicing.

[0003] However, there is an adhesive colloid at the splicing joint of the edge silicon material after the spliced material is squared. It is necessary to cut and separate the colloid joint of the adhered edge silicon material, and then wash off the colloid to facilitate the recycling of the edge silicon material; the current separation and treatment method is to use a wire cutting machine to drive the diamond wire thereon to align with the colloid joint for cutting and separation, and then manually scrub and remove the colloid on the end face of the edge silicon material after cutting.

[0023] A number of silicon material support seats 5 are fixedly arranged on the transmission member 4 at intervals; the silicon material support seat 5 includes a connecting beam 5.1, a connecting member 5.2, and a U-shaped tray 5.3; the connecting beam 5.1 is fixedly arranged parallel to the driving shaft 2 between the two chains 4.2, and the two ends of the U-shaped tray 5.3 are respectively detachably connected to the two ends of the connecting beam 5.1 through the connecting member 5.2 by screws; a number of hollow rubber pads 5.4 are fixed on the inner bottom surface of the U-shaped tray 5.3, and the edge silicon material 18 is placed on the rubber pads 5.4 of the U-shaped tray 5.3. Plastic guard plates 5.5 are respectively fixed on the inner walls on both sides of the U-shaped tray 5.3 by screws to play a protective role on both sides of the edge silicon material 18, so as to avoid damage caused by the direct contact between the edge silicon material 18 and the metal U-shaped tray 5.3 due to vibration during transportation; each U-shaped tray 5.3 is inclined downward toward the flushing head side to facilitate the outflow of the sprayed water, and a limit stop is fixed at the lower end where the U-shaped tray 5.3 is inclined downward to play a limiting role on the edge silicon material 18.

[0026] Two spray water collecting grooves 8 are arranged between the conveying section 4.21 and the return section 4.22 of the chain 4.2 on both sides of the casing 1 along the conveying direction; the side wall of the casing 1 is provided with water outlets 1.3 corresponding to the bottoms of the two spray water collecting grooves 8, and each water outlet 1.3 is respectively connected to a return water tank 9, and each return water tank 9 is connected to a hot water tank 10 through a pump. A filter is installed at the discharge port of the return water tank 9 to filter the debris in the spray water collected in the return water tank 9 and then transport it to the hot water tank through the pump. 10, and then after being electrically heated in the hot water tank 10, it is sent back to the casing 1 by the high-pressure water pump (the setting of the high-pressure water pump is conventional technology, not shown in the drawings); the outlet pipe of one of the hot water tanks 10 is connected with each spray pipe 6 (the connection relationship is conventional technology, not shown in the drawings), and the spray pipe 6 in the front area of ​​the casing 1 sprays the heated spray water onto the edge skin silicon material 18 in the casing 1.
