Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a glove box sealing device. Background Art

[0002] MOCVD is a complex multi-layer thin-layer structure preparation process that is widely used in the production and manufacturing of light-emitting devices such as light-emitting diodes, power electronic devices, and laser components. Many high-brightness LED devices are manufactured on very small substrates, so dedicated wafer handling machines are rarely used. The more common practice in the existing technology is to build a glove box or a laminar flow hood system, and manually handle the wafers using gloves. During the process of transporting or removing the wafer box to or from the reaction chamber, the air environment in the glove box will interact with the reaction chamber. Particles generated by different processes will potentially contaminate the exposed wafers. If particles that fall on the wafer surface are not removed or processed before the deposition reaction, they will be trapped in the thin layer, resulting in impaired product function and stability. Therefore, the glove box is continuously flushed with nitrogen, and high sealing requirements are placed on the threading position.

[0003] In order to achieve the sealing requirement, the fasteners used in the prior art need to be glued after installation. However, even so, air leakage will still occur after long-term use, thereby causing subsequent technical problems affecting product quality. Utility Model Content

[0004] The utility model provides a glove box sealing device, which solves the technical problem in the prior art that, because fasteners need to be glued, air leakage still occurs after long-term use, thereby affecting product quality.

[0005] In order to solve the above problems, the utility model provides a glove box sealing device, including a base, characterized in that: a mounting groove is provided on the outer surface of the base, a sealing hole is provided in the middle of the upper surface, a sealing block is spliced in the sealing hole, and a screw is vertically provided on the side of the upper surface of the base, the sealing block passes through the surface and the bottom to open a threading channel, the threading channel extends to the outer surface of the sealing block to open a mounting incision, a clamping groove is provided in the middle of the lower bottom surface of the clamping block, a mounting port is provided on the side of the clamping groove, a threading opening is extended through the inner bottom surface of the clamping groove to the outer surface of the clamping block, the clamping block passes the screw through the mounting port, so that the clamping groove and the sealing block are spliced and connected, the threading opening and the threading channel are on the same vertical line, and the nut and the cap nut are threadedly connected to the screw.

[0006] Furthermore, the sealing hole and the sealing block are both truncated cone structures.

[0007] Furthermore, the sealing block is made of rubber material.

[0008] Furthermore, the sealing block is provided with three threading channels through the surface and the bottom.

[0009] Furthermore, the diameter of the pressing block is equal to the diameter of the base.

[0010] The beneficial effect of the present invention is that the present application connects the sealing block and the sealing hole with each other. Since the sealing block and the sealing hole are both truncated cone-shaped structures, when the compression block applies pressure to the sealing block, it can achieve a good sealing effect on the sealing hole and the threading channel, preventing nitrogen leakage in the glove box, thereby achieving the technical effect of ensuring the quality of subsequent products.

[0017] In order to make the technical solution of the present invention more clear, the present invention will be further described below with reference to specific embodiments of the drawings.

[0018] like Figure 1-5As shown, a glove box sealing device according to an embodiment of the present invention includes a base 1, an outer surface of the base 1 is provided with a mounting groove 12, a sealing hole 11 is provided in the middle of the upper surface, a sealing block 2 is spliced in the sealing hole, and a screw 13 is vertically provided on the side of the upper surface of the base 1, the sealing block 2 is provided with a threading channel 21 through the surface and the bottom, the threading channel 21 extends to the outer surface of the sealing block 2 and provides a mounting incision 22, a pressing groove 31 is provided in the middle of the lower bottom surface of the pressing block 3, a mounting opening 33 is provided on the side of the pressing groove 31, and a threading opening 32 is provided through the inner bottom surface of the pressing groove 31 and extends to the outer surface of the pressing block 3, the pressing block 3 passes through the screw 13 through the mounting opening 33, so that the pressing groove 31 is spliced and connected with the sealing block 2, the threading opening 32 and the threading channel 21 are on the same vertical line, and the nut 4 and the cap nut 5 are threadedly connected with the screw 13.

[0019] Among them, the sealing hole 11 and the sealing block 2 are both truncated cone-shaped structures. When in use, the sealing block 2 with a truncated cone-shaped structure is spliced and connected with the sealing hole 11 with a truncated cone-shaped structure. When the clamping block 3 squeezes the sealing block 2, the contact area between the sealing block 2 and the inner surface of the sealing hole 11 can be ensured, thereby meeting the sealing requirements.

[0020] The sealing block 2 is made of rubber material. When in use, the sealing block 2 is squeezed by the pressing block 3 to deform it, thereby achieving a sealing effect on the sealing hole 11 and the threading channel 21.

[0021] The sealing block 2 is provided with three threading channels 21 through the surface and the bottom. When in use, the wiring is passed through the threading channels 21 and connected to the internal equipment of the glove box, thereby completing the production of the product.

[0022] The diameter of the pressing block 3 is equal to the diameter of the base 1 .

[0023] Instructions for use: First, install and connect the base 1 to the glove box through the installation groove 12. Since there are plugs at both ends of the wiring, the wiring needs to be inserted into the wire channel 21 through the installation incision 22, and the plug at one end of the wiring needs to be passed through the sealing hole 11 to connect to the operating equipment in the glove box. Then, splice and connect the sealing block 2 to the sealing hole 11, and pass the installation opening 33 on the clamping block 3 through the screw 13 to splice and connect the clamping groove 31 to the sealing block 2. At this time, the wiring just passes through the wire opening 32. Finally, thread the nut 4 to the screw 13 and act on the clamping block 3, so that the clamping block 3 applies pressure to the sealing block 2. The sealing block 2 is deformed after the pressure is applied, and has a sealing effect on the sealing hole 11 and the wire channel 21. Then, thread the cap nut 5 to the screw 13 and act on the nut 4 to limit the nut 4.

[0024] The above embodiments can be combined with each other and further implemented if they are not mutually exclusive.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
