Description

Technical Field

[0001] This utility model relates to the field of photovoltaic solar cell technology, and in particular to a graphite boat gasket enlargement fixture. Background Technology

[0002] As a key load-bearing tool in photovoltaic cell production (diffusion, coating, sintering), the structural integrity and dimensional accuracy of the graphite boat are crucial to ensuring the stability of the production process and the quality of the cells. A graphite boat is typically assembled and secured by multiple precision-machined graphite components using high-strength bolts / screws. This ensures that the bolts maintain a stable preload under high-temperature thermal cycling and vibration environments, preventing loosening and guaranteeing the overall structural rigidity and dimensional stability of the graphite boat. Graphite gaskets play an indispensable role at these fastening points—they are essentially specialized fasteners used for assembling the graphite boat.

[0003] While existing fixtures feature a rigid-flexible composite clamping system that provides high-stability clamping and prevents gasket chipping, breakage, or surface crushing during the hole enlargement process, they lack a slag removal structure. This causes waste generated during hole enlargement to accumulate in the hole where the gasket is placed, affecting the clamping reliability of the fixture and thus reducing product quality.

[0053] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a graphite boat gasket enlargement fixture.

[0054] A graphite boat gasket enlargement fixture includes a base 1, an intermediate support block 2, and a top cover 3, and further includes:

[0058] The spring pad 12 is set on the placement hole 10 and is slidably connected to the intermediate support block 2.

[0059] Place the gasket inside the holder. The raised part of the top cover 3 restricts the displacement of the gasket. The spring pad 12 disperses the local stress on the workpiece and further fixes the gasket, so that the stacked gaskets do not wobble. This enables batch gasket hole enlargement processing and achieves a zero-damage clamping effect.

[0060] A fixing component, mounted on the upper cover 3, is used to fix the base 1, the intermediate support block 2, and the upper cover 3 together on the processing table. The fixing component includes:

[0061] The first fixing hole 13 is provided on the upper cover 3;

[0062] The second fixing hole 14 is provided on the intermediate support block 2. The second fixing hole 14 and the first fixing hole 13 are on the same axis and have the same inner diameter.

[0063] The third fixing hole 15 is provided on the base 1. The third fixing hole 15 and the second fixing hole 14 are on the same axis and have the same inner diameter.

[0064] Bolt 16 is set on the first fixing hole 13 and threadedly connected to the upper cover 3. Bolt 16 is threadedly connected to the intermediate support block 2 and the base 1.

[0065] Screw the bolt 16 into the second fixing hole 14 and the third fixing hole 15 in sequence from the first fixing hole 13 of the upper cover 3, and screw the bolt 16 into the processing table to achieve the fixing effect.

[0066] Reference Figures 1 to 5 A positioning component, disposed on the upper cover 3, is used to establish a reference axis for the fixture. The positioning component includes:

[0067] The first positioning hole 17 is provided on the upper cover 3;

[0068] The second positioning hole 18 is provided on the intermediate support block 2. The second positioning hole 18 and the first positioning hole 17 are on the same axis and have the same inner diameter.

[0070] The positioning pin 20 is set on the first positioning hole 17 and is slidably connected to the upper cover 3. The positioning pin 20 is slidably connected to the middle support block 2 and the base 1.

[0071] Insert the positioning pin 20 into the processing table, then insert the base 1 into the slidingly connected positioning pin 20 through the third positioning hole 19, then insert the middle support block 2 into the slidingly connected positioning pin 20 through the second positioning hole 18, place the shim into the placement hole 10, and then insert the top cover 3 into the slidingly connected positioning pin 20 through the first positioning hole 17 to achieve the positioning effect.

[0072] The slag removal component is installed on the upper cover 3 and is used to quickly clean up the waste slag generated during the hole enlargement operation. The first air duct 4 is installed on the upper cover 3.

[0073] The second air duct 5 is installed on the upper cover 3 and connected to the first air duct 4;

[0074] The air outlet 6 is installed on the first air duct 4 and is threadedly connected to the upper cover 3;

[0075] Air supply duct 7 is fixedly connected to air outlet 6;

[0076] Air outlet 8 is located on the upper cover 3 and connected to the second air duct 5. Air outlet 8 is connected to the enlarged hole on the upper cover 3.

[0077] Slag discharge hole 9 is provided on base 1. Slag discharge hole 9 and placement hole 10 are on the same axis and are connected to each other.

[0078] Open the air outlet 6 so that the air in the air supply pipe 7 enters the first air duct 4, and then enters the second air duct 5 from the first air duct 4. Then the air enters the flared opening from the air outlet 8 connected to the second air duct 5, and blows the waste residue generated in the flared opening out from the slag discharge hole 9 to achieve the slag discharge effect.

[0079] Reference Figures 1 to 5 By setting up the slag discharge assembly, the external air source is introduced into the first air duct 4 connected to the air outlet 6 through the air supply pipe 7, and then the air is introduced into the air outlet 8 through the second air duct 5 connected to the first air duct 4 and blown into the flared opening, so that the waste slag generated by the flared opening is discharged from the slag discharge port under the drive of the airflow, thereby effectively improving the slag discharge effect of the fixture and improving the product quality.

[0080] A redundant component, mounted on the upper cover 3, is used to provide fixation in case the fixing component fails. The redundant component includes:

[0084] The iron plate 24 is set on the second mounting groove 23 and is fixedly connected to the intermediate support block 2.

[0085] When the electromagnet 22 is activated, it generates a magnetic force that attracts the iron block, thus fixing the top cover 3 to the middle support block 2 and achieving a fixing effect.

[0086] Working principle: Refer to Figures 1 to 5 Insert the positioning pin 20 into the processing table, then insert the base 1 into the slidingly connected positioning pin 20 through the third positioning hole 19, then insert the intermediate support block 2 into the slidingly connected positioning pin 20 through the second positioning hole 18, put the shim into the placement hole 10, then put the spring shim 12 that is slidably connected to the intermediate support block 2 into the placement hole 10, and then insert the top cover 3 into the slidingly connected positioning pin 20 through the first positioning hole 17 to achieve the positioning effect;

[0087] Screw the bolt 16 into the second fixing hole 14 and the third fixing hole 15 of the first fixing hole 13 of the upper cover 3 in sequence, and screw the bolt 16 into the processing table until the pressure of the pressure sensor 11 given by the gasket is equal to the normal value. Stop screwing the bolt 16 to achieve the fixing effect. If the bolt 16 becomes loose during the hole expansion work, start the electromagnet 22. The electromagnet 22 generates magnetic force to attract the iron block, so that the upper cover 3 is fixed on the middle support block 2 to achieve the fixing effect.

[0088] Reference Figures 1 to 5When the hole enlargement work is carried out, the air outlet 6 is opened so that the air in the air supply pipe 7 enters the first air duct 4, and then enters the second air duct 5 from the first air duct 4. Then the air enters the enlarged hole from the air outlet 8 connected to the second air duct 5, and blows the waste residue generated by the hole enlargement out from the slag discharge hole 9 to achieve the slag discharge effect.

[0089] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
