Description

Technical Field

[0001] The present invention relates to a glove box with automatic material transfer, in particular to the technical field of glove boxes. Background Art

[0002] A glove box is a sealed device used for material manipulation and experimentation in an inert gas environment (such as nitrogen or argon) or in oxygen- and water-free conditions. It is widely used in fields such as lithium battery research and development, semiconductor packaging, and nuclear material processing. Traditional inert gas glove boxes typically consist of a main chamber, a transition chamber (transfer chamber), a gas purification system, and sealing components to ensure contamination-free transfer of materials between the external environment and the interior of the chamber.

[0003] However, the glove boxes currently on the market still have the following problems in terms of automatic material transfer, tray positioning and adjustment, and convenient operation of the sealing cover:

[0004] 1. Material transfer relies on manual operation, with a low degree of automation. After placing items in the transition chamber and waiting for the pressure between the box and the transition chamber to reach equilibrium, an operator must still wear gloves and enter the chamber, manually open the sealing cover, remove the items from the transition chamber, and transfer them to the operating station. This increases the number of steps and reduces efficiency. Frequent opening of the sealing cover may cause atmospheric fluctuations.

[0005] 2. Pallet transfer is unstable and cannot be docked smoothly. Pallets in the transition compartment need to be manually pushed into the box. However, due to the lack of a precise guide mechanism, the pallets are prone to deviation during movement, resulting in unstable docking with the moving parts in the box, affecting the continuity of the automated production line.

[0006] 3. The pallet locking method is fixed and cannot adapt to different sizes. The pallet fixing method of existing glove boxes is mostly a single clip or bolt locking method. The clamping position cannot be flexibly adjusted according to the pallet size. Large-sized pallets may not be fixed, and small-sized pallets may be clamped unstable. Manual adjustment is required to replace the pallet, affecting operational efficiency.

[0007] 4. The sealing cover is cumbersome to operate, affecting work efficiency. The transition compartment sealing cover of a traditional glove box usually needs to be manually opened and closed by the operator inside the box, and automatic linkage cannot be achieved. Frequent manual operation may cause seal wear and reduce equipment life. Summary of the Invention

[0008] Purpose of the invention: To propose a glove box with automatic material transfer to solve the above problems existing in the prior art.

[0009] Technical solution: A glove box with automatic material transfer, including:

[0010] A bracket, a box body installed above the bracket, and a transition cabin installed on one side of the box body and connected to the box body. The box body and the transition cabin are both provided with a moving part for mutually transmitting items. A sealing component installed on the inner wall of the box body is provided between the two moving parts.

[0011] The moving part includes a frame, a linear guide rail mounted on the frame, a moving block and a fixed block mounted on the linear guide rail, a screw rod mounted on the frame for driving the moving block to move axially, a first motor for driving the screw rod to rotate is provided on one side of the frame, two racks parallel to each other are provided in the moving block, a gear shaft meshing with each other is provided between the two racks, a second motor for driving the gear shaft is provided on one side of the moving block, and a tray is placed above the moving block and the fixed block;

[0012] The sealing assembly includes a guide frame installed on the inner wall of the box, a first sealing cover slidably installed in the guide frame, the guide frame is provided with a through hole for limiting the cylinder stroke, and a cylinder is provided in the box to drive the first sealing cover to move; a vacuum tube for adsorbing the first sealing cover close to the inner wall of the box is provided on the side of the guide frame close to the transition cabin.

[0013] In a further embodiment, a ring light is provided on the top of the box, a temperature control sensor is provided near the operating platform of the box, two glove interfaces and an observation window are provided at the front and back of the box, and a transfer port for transferring items is also provided at the corresponding position of the box and the transition cabin.

[0014] In a further embodiment, there are at least two transition cabins, and the size ratio of the two transition cabins is 1:2. The middle section of the transition cabin is provided with a pressure gauge for detecting the pressure inside the transition cabin. The transition cabin is provided with a second sealing cover at a position corresponding to the first sealing cover, and the second sealing cover is used to seal the inlet and outlet positions of the transition cabin.

[0015] In a further embodiment, a truss is provided above the second sealing cover, one end of the truss is movably connected to the transition cabin and the other end is detachably connected to the transition cabin with a snap. The middle section of the truss is provided with a top screw that cooperates with the circumferential rotation of the second sealing cover, the top screw cooperates with the truss thread, and the transition cabin is also provided with a damping rod for slow rotation of the second sealing cover.

[0016] In a further embodiment, the moving block is slidably matched with the linear guide rail, the fixed block is locked with the linear guide rail by screws, the screw rod is circumferentially rotated with the frame, the rack and the gear shaft are both clearance-matched with the moving block, and the rack tightens the tray.

[0017] In a further embodiment, the guide frame is connected to the box body by screws, the first sealing cover is slidably matched with the guide frame, and the cylinder is used to adjust the opening / closing of the first sealing cover.

[0018] Beneficial Effects: The present invention proposes a glove box with automatic material transfer. Independent moving parts are provided in both the box body and the transition chamber. The movement of the tray is controlled by a linear guide rail and a first motor (servo motor). The first motor controls axial movement, and the second motor controls the extension and retraction of the rack. Automatic material transfer is achieved. Through the linkage of the moving part and the sealing assembly, the tray can automatically enter the box body from the transition chamber after pressure balance, reducing manual intervention.

[0019] The moving block has two built-in racks that synchronize their extension and retraction through the rotation of the gear shaft, pressing or clamping the edges of the pallet from both sides. The fixed block and the linear guide rail are locked to provide a reference positioning, thereby ensuring that the pallet's movement direction does not deviate when the moving block transfers the pallet. The second motor drives the gear shaft to rotate, thereby controlling the movement of the rack within the moving block and automatically adjusting the rack extension length.

[0020] The cylinder and vacuum tube are controlled in coordination. In the opening phase, the cylinder pulls back the first sealing cover, and the vacuum tube instantly releases the adsorption force. In the closing phase, the cylinder pushes the first sealing cover back, and the vacuum tube is activated to increase the sealing pressure. The pressing force of the second sealing cover is finely adjusted by rotating the top screw, and the damping rod prevents it from closing too quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The moving part 6 includes a frame 61, a linear guide 63 installed on the frame 61, a moving block 66 and a fixed block 67 installed on the linear guide 63, the moving block 66 slidingly cooperates with the linear guide 63, the fixed block 67 is locked with the linear guide 63 by a screw, and is installed on the frame 61 for driving the screw rod 62 for axial movement of the moving block 66, the screw rod 62 cooperates with the frame 61 for circumferential rotation, and a first motor 64 that drives the screw rod 62 to rotate is provided on one side of the frame 61, two racks 651 parallel to each other are provided in the moving block 66, and a gear shaft 652 that meshes with each other is provided between the two racks 651, the rack 651 and the gear shaft 652 are both clearance-matched with the moving block 66, and the rack 651 tightens the tray 4; a second motor 65 for driving the gear shaft 652 is provided on one side of the moving block 66, and the tray 4 is placed above the moving block 66 and the fixed block 67;

[0037] The sealing assembly 5 includes a guide frame 53 installed on the inner wall of the box body 2, the guide frame 53 is connected to the box body 2 by screws, and a first sealing cover 51 is slidably installed in the guide frame 53. The first sealing cover 51 and the guide frame 53 are slidably matched. The guide frame 53 is provided with a through hole 55 for limiting the stroke of the cylinder 52. A cylinder 52 for driving the first sealing cover 51 to move is provided in the box body 2; the cylinder 52 is used to adjust the opening and closing of the first sealing cover 51; a vacuum tube 54 for adsorbing the first sealing cover 51 close to the inner wall of the box body 2 is provided on the side of the guide frame 53 close to the transition cabin 3.

[0038] Working principle: First, the moving part 6 in the box body 2 is in standby mode, close to the transition chamber 3; the ring light provides lighting, and the temperature control sensor maintains a constant temperature of 25°C; the second sealing cover 31 is opened, and the pressure in the transition chamber 3 is the same as that outside;

[0039] Open the second sealing cover 31 from the outside, release the buckle when in the open state, rotate the top screw 33 in the reverse direction, and the damping rod 32 assists in slowly opening it, and place the items on the tray 4 in the transition compartment 3.

[0040] The second motor 65 starts the gear shaft 652 to rotate, and the racks 651 on both sides move outward or inward synchronously to press or clamp the edge of the tray 4 (to prevent shaking);

[0041] Then the truss 34 is locked by snaps, the rotating top screw 33 presses the sealing cover, and the damping rod 32 buffers and closes to form a preliminary seal; the transition chamber 3 is evacuated to a vacuum through the valve, and the air is exhausted; high-purity argon gas is filled to the same pressure as the box 2 (monitored by the pressure gauge 35);

[0042] The piston rod of the cylinder 52 retracts and pulls back the first sealing cover 51, which slides along the guide frame 53 to fully open the passage between the transition chamber 3 and the box body 2; (the through hole 55 limits the stroke of the cylinder 52 to prevent excessive extension, which may cause leakage of the first sealing cover 51)

[0043] The first motor 64 drives the screw 62 to rotate; the moving block 66 drives the tray 4 along the linear guide 63 toward the box body 2 and into the operating platform area of the box body 2; when the tray 4 slowly enters the box body 2, the moving block 66 in the box body 2 captures the tray 4, locks the tray 4, and transfers it to the operating platform area set by the box body 2. Then the moving block 66 in the transition cabin 3 waits, and the rack 651 is reset under the drive of the second motor 65, waiting for the return of the tray 4;

[0044] After the gloves are installed on the glove interface 22, the items transferred in the box 2 are manually operated, and the observation window 21 monitors the operation process;

[0045] The screw 62 rotates in the opposite direction, and the moving block 66 carries the tray 4 back to the transition chamber 3; the piston rod of the cylinder 52 extends to push back the first sealing cover 51, and the vacuum tube 54 starts adsorption to enhance the seal; the inert gas is discharged to normal pressure, and the second sealing cover 31 is opened to take out the processed items; the rack 651 of the moving part 6 releases the tray 4 and waits for the next round of operation.

[0046] As described above, although the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself; various changes in form and details may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
