[0002] The ultra-low water and oxygen content glove box used to produce telluride cadmium alloy is a special sealed environment equipment that can provide a highly controlled, water-free and oxygen-free (i.e. ultra-low water and oxygen content) working space; this glove box is usually used for the processing of sensitive materials, especially in semiconductors, optoelectronic materials, nanotechnology and other fields that require strict control of environmental conditions; telluride cadmium alloy (such as mercury cadmium telluride, HgCdTe) is an important infrared detection material that is extremely sensitive to water and oxygen content, so the environmental conditions need to be strictly controlled during the production process to prevent the material from oxidation or other contamination; ultra-low water and oxygen content glove boxes usually have the following characteristics: sealing, inert gas environment and gas purification system to ensure that the water and oxygen content in the environment is extremely low.

[0003] In the conventional glove box for producing tellurium-cadmium alloy, only a storage window is opened on one side for temporarily placing tellurium-cadmium alloy samples, which makes it difficult for workers in other directions to place tellurium-cadmium alloy samples, limiting the usage scenarios. At the same time, the storage window opened on the side cannot ensure the vertical access to the temporarily replaced tellurium-cadmium alloy samples, which is easy to knock over the tellurium-cadmium alloy samples, thereby affecting the subsequent operation of the experiment. For example, a Chinese public patent with patent number CN218534631 U, although the cited document has a double-door setting, which is convenient for placing samples in both directions and improves the convenience of temporarily placing samples, it still has certain limitations in use, that is, the placement mechanism in the document lacks positioning for the samples, resulting in the problem that the samples are still easy to tip over and overturn during the placement process. Therefore, in view of the above cited problems, a glove box with ultra-low water and oxygen content for the production of tellurium-cadmium alloy is proposed to solve them. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides a glove box with ultra-low water and oxygen content for producing tellurium cadmium alloy, comprising a glove box body;

[0006] The glove box body is connected with a storage assembly, and the storage assembly includes a storage compartment, which is a rectangular box structure with upper and lower openings; the side of the storage compartment is connected with a side pipe;

[0007] A set of lifting components is respectively arranged on the inner walls of both sides of the storage compartment; a supporting plate is installed between the two sets of lifting components; a rectangular groove is opened on the upper surface of the supporting plate and two sets of clamping components are arranged therein;

[0008] The lifting assembly comprises a lifting seat arranged on the inner wall of the storage assembly, a positioning seat is slidably arranged in the lifting seat, and two positioning seats are arranged opposite to each other;

[0009] The clamping assembly includes a positioning plate arranged in the supporting plate, a plurality of shrinkage columns are connected to the side of the positioning plate, a plurality of shrinkage columns are sleeved with sleeve columns outside, and a clamping plate is commonly installed on the sides of the plurality of sleeve columns.

[0010] As a further improvement of the utility model, a vacuum generator is also installed on the glove box body; a vacuum generating tube is connected to the side of the vacuum generator; one end of the vacuum generating tube is connected to the glove box body, and its side is also connected to the side tube through a solenoid valve.

[0011] As a further improvement of the utility model, a plurality of the shrinkage columns and sleeve columns are sleeved with compression springs on their exteriors. Both ends of the compression springs are respectively connected to the side surfaces of the positioning plate and the clamping plate.

[0015] The utility model discloses a glove box with ultra-low water and oxygen content for producing tellurium-cadmium alloy. In actual use, the storage component is connected to the glove box body, and the vacuum generator is connected to the storage component, so that the tellurium-cadmium alloy sample can be individually vacuumed in the storage component. By storing the tellurium-cadmium alloy sample in the storage component, the opportunity for the operator to directly contact the inside of the glove box body can be reduced, thereby reducing the risk of introducing pollutants and maintaining the ultra-low water and oxygen environment inside the glove box body.

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.

[0023] Example

[0024] Depend on Figure 1-4 Provided is a glove box with ultra-low water and oxygen content for producing cadmium telluride alloy, comprising a glove box body 1;

[0025] The glove box body 1 is connected with a storage assembly 5, which includes a storage compartment 51. The storage compartment 51 is a rectangular box structure with upper and lower openings. The side of the storage compartment 51 is connected with a side pipe 4.

[0026] A set of lifting components 6 are respectively arranged on the inner walls of both sides of the storage compartment 51; a supporting plate 7 is installed between the two sets of lifting components 6; a rectangular groove is opened on the upper end surface of the supporting plate 7 and two sets of clamping components 8 are arranged therein;

[0027] The lifting assembly 6 includes a lifting seat 61 disposed on the inner wall of the storage assembly 5, and a positioning seat 66 is slidably disposed in the lifting seat 61, and two positioning seats 66 are disposed opposite to each other;

[0028] The clamping assembly 8 includes a positioning plate 81 disposed in the supporting plate 7 , a plurality of shrinkage columns 82 are connected to the side of the positioning plate 81 , a plurality of shrinkage columns 82 are sleeved with sleeve columns 83 on the outside, and a clamping plate 84 is installed on the side of the plurality of sleeve columns 83 .

[0029] In the present embodiment, in actual use, by providing a connection between the storage component 5 and the glove box body 1, and in conjunction with the connection between the vacuum generator 2 and the storage component 5, the tellurium-cadmium alloy sample can be individually vacuumed in the storage component 5. By storing the tellurium-cadmium alloy sample in the storage component 5, the chance of the operator directly contacting the interior of the glove box body 1 can be reduced, thereby reducing the risk of introducing contaminants and maintaining an ultra-low water-oxygen environment in the glove box body 1. At the same time, compared with the traditional glove box setting, the present application uses the storage window on the glove box body 1 in conjunction with the storage component 5, so that the tellurium-cadmium alloy sample can be bidirectionally transported to the glove box body 1 via the storage component 5. The bidirectional transport means that new tellurium-cadmium alloy samples can be delivered into the glove box body 1 or the processed tellurium-cadmium alloy samples can be taken out without opening the glove box body 1, which can save time and improve operating efficiency.

[0030] Furthermore, by means of the mutual movement cooperation of the lifting assembly 6, the supporting plate 7 and the clamping assembly 8 arranged in the storage assembly 5, the tellurium-cadmium alloy sample to be tested can be stably transported in the storage assembly 5, so that the tellurium-cadmium alloy sample can be accurately delivered into the glove box body 1 or taken out from the storage assembly 5. At the same time, for the tellurium-cadmium alloy samples that are fragile or easily deformed, the two sets of clamping assemblies 8 can provide a safer operation method, reduce the chances of operators directly contacting these samples, and thus improve the safety of operation.

[0031] Specifically, refer to Figure 1-2 A vacuum generator 2 is also installed on the glove box body 1; a vacuum generating tube 3 is connected to the side of the vacuum generator 2; one end of the vacuum generating tube 3 is connected to the glove box body 1, and its side is also connected to the side tube 4 through a solenoid valve.

[0032] In this embodiment, in actual use, when the user needs to use the glove box body 1, the tellurium cadmium alloy sample to be tested is first sent into the glove box body 1 from the storage window of the glove box body 1, and then the vacuum generator 2 is connected with the vacuum generating tube 3, and the vacuum generating tube 3 is connected with the glove box body 1, so that the vacuum generator 2 can be driven to perform a vacuum operation on the glove box body 1.

[0033] It should be noted that in order to ensure the vacuum environment of the storage component 5 and the glove box body 1 so as to facilitate the storage of samples, in a preferred embodiment, the connection between the vacuum generating tube 3 and the glove box body 1 and the connection between the vacuum generating tube 3 and the side tube 4 are all separately connected, and two sets of solenoid valves are arranged in the vacuum generating tube 3 for separately connecting and closing the storage component 5 and the glove box body 1. The power connection method of the solenoid valve is the prior art, and the control circuit can be realized through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0034] Specifically, refer to Figure 2-3 A compression spring 85 is sleeved on the outside of the plurality of contraction columns 82 and the sleeve column 83. The two ends of the compression spring 85 are respectively connected to the side surfaces of the positioning plate 81 and the clamping plate 84.

[0035] In this embodiment, the compression spring 85 can be used to reset and rebound and control the movement of the clamping plate 84, and then the two clamping plates 84 are used to extrude and limit the sample. In actual use, when the tellurium cadmium alloy sample is completely placed between the two sets of clamping plates 84 and supported by the supporting plate 7, the compression spring 85 can reset and rebound, so that the two clamping plates 84 can move in opposite directions.

[0036] Specifically, refer to Figure 2 and Figure 4 The lifting assembly 6 also includes a cover 62 arranged on the side of the lifting seat 61. A groove is provided between the cover 62 and the lifting seat 61 for the positioning seat 66 to slide. A forward and reverse motor 63 is assembled in the lifting seat 61. A lead screw 64 is connected to the output end of the forward and reverse motor 63. A nut slide 65 is meshed with the outside of the lead screw 64. The nut slide 65 is connected to the bottom of the positioning seat 66.

[0037] In this embodiment, the lifting seat 61 and the cover 62 can be used to limit the positioning seat 66. During use, the forward and reverse motor 63 can be used to drive the screw 64 to rotate. During this period, when the screw 64 is in forward rotation, the support plate 7 is in an ascending state, and when the screw 64 is in reverse rotation, the support plate 7 is in a descending state.

[0038] Specifically, refer to Figure 1-2 A sealed hatch door 52 is rotatably connected to the opening of the upper end surface of the storage compartment 51 , and a side door 53 is rotatably installed on the side of the storage compartment 51 , and the side door 53 is located inside the glove box body 1 .

[0039] In this embodiment, the side door 53 is used to take out the sample. In actual use, after the vacuum operation is completed in the storage component 5, the user can open the side door 53, take out the tellurium cadmium alloy sample in the storage component 5 from the support plate 7, and operate in the glove box body 1. In a preferred embodiment, the side door 53 and the sealed cabin door 52 can be sealed and connected to the storage cabin 51.

[0040] The utility model discloses a glove box with ultra-low water and oxygen content for producing tellurium cadmium alloy:

[0041] Step 1: In actual use, when the user needs to use the glove box body 1, firstly, the tellurium-cadmium alloy sample to be tested is placed into the glove box body 1 through the storage window of the glove box body 1, and then the vacuum generator 2 is connected with the vacuum generating tube 3, and the vacuum generating tube 3 is connected with the glove box body 1, so that the vacuum generator 2 can be driven to perform a vacuum operation on the glove box body 1;

[0042] Step 2: When the user needs to place the new tellurium-cadmium alloy sample in the glove box body 1, first open the sealed hatch 52 to expose the opening above the storage compartment 51, and then the user connects the power supply to 63 in the two sets of lifting components 6, so that the forward and reverse motors 63 can drive the lead screw 64 to rotate. At this time, the nut slide 65 and the positioning seat 66 engaged with the outside of the lead screw 64 can move vertically in a straight line within the travel range of the lead screw 64 due to the limitation of the lifting seat 61. At this time, the positioning seat 66 and the support plate 7 are installed so that the support plate 7 can be vertically lifted and lowered along the travel range of the lead screw 64; during this period, when the lead screw 64 is in forward rotation, the support plate 7 is in an ascending state, and when the lead screw 64 is in reverse rotation, the support plate 7 is in a descending state;

[0043] Step 3: The user controls the lifting and lowering of the support plate 7 to move the support plate 7 upward. At this time, the user can place the tellurium-cadmium alloy sample to be operated between the two groups of clamping assemblies 8. At this time, the tellurium-cadmium alloy sample squeezes the clamping plate 84, so that the sleeve column 83 can slide to the outside of the contraction column 82. At this time, the set clamping plate 84 can squeeze the compression spring 85. When the tellurium-cadmium alloy sample is completely placed between the two groups of clamping plates 84 and supported by the support plate 7, the compression spring 85 is reset and rebounded, so that the two clamping plates 84 can move in opposite directions, and then the two clamping plates 84 can be used to squeeze and limit the tellurium-cadmium alloy sample;

[0044] Step 4: After the two groups of clamping components 8 have completed the positioning of the tellurium cadmium alloy sample, the user can drive the lifting component 6 to make the supporting plate 7 move downward to the bottom of the storage compartment 51. During this period, the user closes the sealed door 52 to make the entrance of the storage component 5 in a sealed state. The tellurium cadmium alloy sample is driven to the side of the side door 53 by the supporting plate 7. At this time, the user controls the vacuum generator 2 and opens the solenoid valve in the side pipe 4, so that the vacuum generator 2 can use the side pipe 4 to evacuate the storage component 5, thereby evacuating the tellurium cadmium alloy sample in the storage component 5, thereby reducing the risk of introducing pollutants and maintaining the ultra-low water and oxygen environment inside the glove box body 1;

[0045] Step 5: After the vacuuming operation is completed in the storage assembly 5 , the user can open the side door 53 , take out the cadmium telluride alloy sample in the storage assembly 5 , and perform operations in the glove box body 1 .

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
