[0002] A vacuum glove box is a laboratory device that fills a high-purity inert gas into the box body and circulates to filter out the active substances therein. It is also called a glove box, an inert gas protection box, a dry box, etc. It mainly removes O2, H2O, and organic gases. It is widely used in ultra-pure environments without water, oxygen, and dust, such as: the forming of low-oxygen high (ultra)-pure materials, lithium-ion batteries and materials, semiconductors, supercapacitors, special lamps, laser welding, brazing, etc. This product is an ideal device for scientific experiments in institutions of higher learning, research units, and enterprise laboratories, and is widely used in departments such as biochemistry, metallurgy, electronics, chemical engineering, geology, minerals, and medicine.

[0003] A glove box is a sealed box body with a transparent panel made of plexiglass in the front, and two gloves are installed on the panel. Operations inside the box can be carried out through the gloves. The prior art has disclosed the following technologies:

[0004] The patent with the publication number CN104908063A and the patent name "A Vacuum Glove Box" discloses the following content: It includes a box body, a box cover, an air extraction chamber, a mobile terminal, and a digital microscope. A tool slot is provided on the inner surface of the box body. The box body is provided with rubber gloves and a lamp box. A bolt tightener is arranged between the rubber gloves and the box body. A hinge device is arranged between the box body and the box cover, and the hinge device is mounted on the lamp box. The air extraction chamber is provided with a gas extraction port and an inert gas replenishment port. A barometer is installed above the air extraction chamber. The mobile terminal is located inside the box body. A titanium alloy hose is installed on the back of the mobile terminal, and a magnet is installed at the end of the titanium alloy hose. The digital microscope is located in the tool slot. The vacuum glove box has the advantages of video recording, taking photos, and microscopic functions.

[0005] The patent with the publication number CN109093654B and the patent name "A fully transparent vacuum glove box" discloses the following content: It includes a box body, a first vacuum valve, a first pressure gauge, a transition chamber, a second vacuum valve, a second pressure gauge, a box door, a workbench, gloves, a sealing connector, and an auxiliary lighting device. The first vacuum valve is inserted into the inner side of the through hole on the left side of the top of the box body, and the connection part is sealed with sealant. The first pressure gauge is inserted into the inner side of the through hole on the right side of the top of the box body, and the connection part is sealed with sealant. To solve the problem that the gloves need to be disassembled and replaced, and the sealing performance at the connection part is poor, a sealing connector is provided. By installing a sealing sleeve, the gap between the gloves and the box body at the connection part is reduced. At the same time, the outer ring cooperates with the inner ring and is embedded in the inner and outer sides of the sealing sleeve, reducing the gap when the sealing sleeve is installed, greatly enhancing the sealing performance, and thus achieving the effect of enhancing the sealing performance at the connection part between the gloves and the box body.

[0006] The above-mentioned patent vacuum glove box solves the problems of the sealing and vacuum pumping of the glove box, but does not involve the problems of the forming and heating melting of small zinc ingots, how to achieve automated forming, and how to save the turnover time. How to solve the above situation has become a technical problem to be solved by those skilled in the art. Summary of the Invention

[0013] In one embodiment, the crucible assembly includes an outer graphite crucible and a quartz crucible sleeved inside the graphite crucible.

[0014] In one embodiment, the heating device includes a heating coil disposed inside the box body, an intermediate frequency furnace disposed outside the box body, and a power adjustment knob disposed on the intermediate frequency furnace. The heating coil is vertically arranged, both ends of the heating coil are respectively connected to the intermediate frequency furnace, and the inner diameter of the heating coil is larger than the outer diameter of the graphite crucible.

[0015] In one embodiment, the pouring assembly includes a pourer positioner, a pourer rotating rod for driving the pourer positioner to rotate, and a rotation guiding assembly for increasing the rotation stability of the pourer positioner.

[0016] In one embodiment, the pourer rotating rod is horizontally and longitudinally arranged inside the box body, the pourer rotating rod is driven by a pourer motor, the pourer positioner is in a barrel shape, the outer diameter of the graphite crucible is smaller than the inner diameter of the pourer positioner, and a rotation positioning hole allowing the pourer rotating rod to pass through is provided at the top of the outer wall of the pourer positioner.

[0017] In one embodiment, the rotation guiding assembly includes two arc-shaped guiding tracks respectively arranged on the front and rear inner side walls of the box body. The two arc-shaped guiding tracks on the same side are concentrically arranged, and their centers are both located on the axis line of the pourer rotating rod. The two arc-shaped guiding tracks on the front and rear inner side walls of the box body are correspondingly positioned to form two groups of arc-shaped track assemblies;

[0018] The rotation guiding assembly further includes two horizontally and longitudinally arranged limiting rods, and both ends of each limiting rod are respectively in sliding fit with a corresponding group of arc-shaped track assemblies;

[0019] Limiting holes allowing the corresponding limiting rods to pass through are respectively provided on the left and right sides at the bottom of the outer wall of the pourer positioner.

[0020] Specifically, the setting of the two limiting rods and the two groups of arc-shaped track assemblies increases the stability of the pourer positioner.

[0024] Working principle:

[0025] Open the intake valve and exhaust valve of the glove box, introduce inert gas through the intake valve, and discharge air through the exhaust valve; feed materials from the right glove port into the quartz crucible embedded in the graphite crucible placed in the heating coil. Rotate the power adjustment knob of the intermediate frequency furnace to adjust to an appropriate power to heat and melt the zinc material until it becomes liquid. After that, through the action of the overhead crane motor, lift the electric lifting rod to raise the crucible until the lower bottom surface is higher than the upper surface of the heating line of the intermediate frequency furnace. Then, the overhead crane motor drives the graphite crucible to move left, right, forward, and backward to a suitable position through the load-bearing hook. After the overhead crane motor lowers the electric lifting rod and completely places the graphite crucible in the tilter locator, after positioning by extending and retracting the tilter motor, rotate the tilter motor. The connection between the graphite crucible and the electric lifting rod rotates through the bearing, and the limit rod slides along the arc-shaped guide rail and slowly tilts to a set appropriate position to complete a pouring operation. The tilter motor rotates reversely to reset, and then perform the positioning operation again, pouring materials into each mold groove in turn. After the pouring is completed, place the graphite crucible back into the heating coil through the action of the overhead crane motor. After the zinc liquid on the mold solidifies, use tweezers to remove it, and then complete one forming operation.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention is reasonably designed, and the structure design in the transfer and transportation process is ingenious. The zinc material is melted in the glove box, and the glove box is filled with inert gas, which avoids the zinc material from being oxidized by contacting with air during the forming process. In addition, the transfer mechanism drives the crucible assembly to move and lift, and the tilting assembly pours the materials in the crucible assembly into the mold assembly. After the glove box door is opened, multiple zinc materials can be placed into the glove box at one time. After the zinc material is formed in the mold once, it is demolded through the glove port and placed on one side inside the glove box. After repeating the above process multiple times, open the glove box door once to take out multiple formed zinc materials. Therefore, the setting of this glove box improves the product quality, increases the work efficiency and sense of security.

[0028] 2. A quartz crucible and an intermediate frequency furnace heating coil are provided inside the glove box. By rotating the power adjustment knob of the intermediate frequency furnace to adjust to an appropriate power to heat and melt the zinc material in the quartz crucible, the heating temperature and heating time can be controlled.

[0029] 3. After positioning by extending and retracting the tilter motor, rotate the tilter motor. The connection between the graphite crucible and the electric lifting rod rotates through the bearing, and the limit rod slides along the arc-shaped guide rail and slowly tilts to a set appropriate position. The setting of this structure increases the stability of the pouring process. Description of the drawings
