Description

Technical Field

[0001] The utility model relates to the technical field of quartz boat production, in particular to a dustproof device used on a slotting machine. Background Art

[0002] Solar photovoltaic cells are a new type of cell that converts sunlight directly into electrical energy. Currently, silicon photovoltaic cells based on silicon are commonly used, including single-crystal silicon, polycrystalline silicon and amorphous silicon photovoltaic cells. In the preparation process of solar photovoltaic cells, silicon wafers need to go through processes such as texturing, diffusion, etching, coating and printing in sequence. Quartz boat is a commonly used wafer carrier.

[0003] The quartz boat includes panels on both sides and a slotted rod in the middle. The quartz slotted rod is made by slotting a quartz rod. When slotting the quartz rod, the existing slotting machine usually directly exposes it to the air. Therefore, the quartz powder generated during the slotting process is easy to escape into the air, posing a threat to the health of the operator. Utility Model Content

Based on the embodiments of 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.

[0025] The utility model provides a dustproof device for a slotting machine, such as Figures 1 to 3 As shown, it includes a body 1, a workbench 2 arranged on the body 1, a protective cover 3 arranged on the body 1, and a rotating screw 4 arranged on one side of the protective cover 3 and rotating in a horizontal direction, a reduction motor 5 for driving the rotating screw 4 is arranged on the protective cover 3, a first moving block 6 is arranged on the rotating screw 4, a grooved part 7 is arranged at the bottom of the first moving block 6, a protective door 8 is slidably arranged on the side of the protective cover 3 away from the rotating screw 4, a dust suction port 9 is opened on the side of the protective cover 3 close to the rotating screw 4, and a dust suction part 10 is connected to the dust suction port 9.

[0028] Furthermore, the spray mechanism 12 includes a spray screw 12a rotatably arranged on the protective cover 3 along a direction parallel to the rotating screw 4 and a second movable block 12b cooperatively arranged on the spray screw 12a, and a first spray pipe 13 is arranged on the second movable block 12b, one end of the first spray pipe 13 is movable through the protective cover 3, and a spray head 14 is arranged obliquely downward at the other end of the first spray pipe 13.

[0029] Furthermore, a first synchronous wheel 15 is disposed at the end of the rotating screw 4 , a second synchronous wheel 16 is disposed at the end of the spraying screw 12 a , and a synchronous belt 17 is disposed between the first synchronous wheel 15 and the second synchronous wheel 16 .

[0030] Furthermore, a funnel-shaped material guide pipe 18 is provided at the bottom of the dust suction pipe 10 a , and the dust collecting box 11 is threadedly connected to the bottom of the material guide pipe 18 .

[0031] Furthermore, a water outlet 19 is provided on one side of the workbench 2 close to the rotating screw 4 , and a water receiving frame 20 connected to the water outlet 19 is provided at the bottom of the machine body 1 .

[0032] Furthermore, the workbench 2 is tiltedly disposed on the machine body 1 , and a horizontal plane at a side of the workbench 2 close to the water outlet 19 is lower than a horizontal plane at a side of the workbench 2 close to the spray screw 12 a .

[0033] Furthermore, a water pump 21 is disposed on one side of the water receiving frame 20 , and a second spray pipe 22 connected to the first spray pipe 13 is disposed at the output end of the water pump 21 .

[0034] Furthermore, the first spray pipe 13 and the second spray pipe 22 are both made of corrugated hose material.

[0035] When it is necessary to groove the groove rod, first fix the groove rod on the workbench 2 (the structure of fixing the groove rod is the prior art, so it will not be described in detail, and it does not affect the technical scope actually protected by this application), then close the protective door 8, turn on the reduction motor 5, drive the first moving block 6 to drive the groove member 7 to move back and forth (the groove member 7 includes a plurality of saw blades arranged side by side and a motor for driving the saw blades to rotate, which are all prior art, so they will not be described in detail, and it does not affect the technical scope actually protected by this application), groove the groove rod, and during the rotation of the rotating screw 4, the first synchronous wheel 15, the second synchronous wheel 16 and the synchronous belt 17 drive the spray screw 12a to rotate synchronously, so the second moving block 12b moves synchronously with the first moving block 6, and during the groove opening process, the distance between the spray head 14 and the groove member 7 remains unchanged, and the spray head 14 always tilts downward to the groove member 7 and the groove rod being grooved are sprayed, and the dust suction piece 10 is turned on to suck the quartz dust generated in the protective cover 3; the sewage generated in the spraying process enters the water receiving frame 20 at the bottom of the machine body 1 through the water outlet 19 along the inclined workbench 2, and the water pump 21 sucks the water above the water receiving frame 20 (most of the dust will be deposited at the bottom of the water receiving frame 20), and then sprays through the second spray pipe 22 and the first spray pipe 13 to achieve water recycling; since the protective door 8 is closed during the groove processing, the quartz dust generated is all in the protective cover 3, and then sprayed through the spray pipe and sucked by the dust suction piece 10, so that part of the dust enters the dust collecting box 11 through the dust suction pipe 10a, and part of the dust enters the water receiving frame 20 through the spray water, thereby preventing the quartz dust generated during the groove processing from escaping into the air and avoiding threats to the health of the operator.

[0036] By setting up the synchronous belt 17, the second moving block 12b and the spray head 14, the first moving block 6 drives the slotting part 7 to move back and forth for slotting, and the second moving block 12b drives the spray head 14 to move synchronously, so that the spray head 14 always sprays the slot rod being slotted, which can not only allow a part of the dust to directly enter the water receiving frame 20 with the spraying water, but also spray the slotting part 7 to cool it down.

[0037] By providing the guide pipe 18 and the dust box 11, the dust sucked into the dust collection pipe 10a by the vacuum machine 10b will enter the dust box 11 below through the funnel-shaped guide pipe 18. When there is a lot of dust in the dust box 11, the dust box 11 can be rotated to separate the dust box 11 from the guide pipe 18, and the dust box 11 can be cleaned. The structure is simple and the dust box 11 is easy to clean.

[0038] By means of the inclined working table 2, the water receiving frame 20 and the water pump 21, the spray water can be recycled to avoid the waste of water resources.

[0039] By configuring the first spray pipe 13 and the second spray pipe 22 as corrugated hoses, the first spray pipe 13 and the second spray pipe 22 can both be extended and retracted within a certain range. At the same time, since the slots of the slotted rod need to be small, the slotted part 7 only needs to move back and forth within a smaller range. Therefore, when the second moving block 12b drives the first spray pipe 13 to move synchronously with the slotted part 7, this can be achieved through the extension and retraction of the first spray pipe 13 itself, and will not cause the connection between the first spray pipe 13 and the second spray pipe 22 to loosen.

[0040] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
