Description

Technical Field

[0001] The utility model relates to the technical field of crucible clamping, in particular to a crucible clamping and gripping device. Background Technique

[0002] A crucible is a cup-shaped vessel used in laboratories, mainly for high-temperature heating of solids, evaporation, concentration or crystallization of solutions, and burning of solid substances. A crucible is a vessel or melting pot made of extremely refractory materials. It is mainly used in chemical laboratories for high-temperature heat treatment of solid substances and operations such as evaporation, concentration or crystallization of solutions.

[0003] At present, as the application field of crystals is getting larger and larger, the requirements for crystal size specifications are also increasing, and the problem of cleaning large-sized crucibles has followed. Traditional crucible cleaning requires manual use of alcohol. Wiping and cleaning with lint-free cloth is inefficient and the wiping is not clean. Moreover, heavy crucibles cannot be emptied and cleaned, which directly leads to contamination of the raw materials after being loaded into the crucible. Therefore, it is unlikely to rely on manual assistance with simple devices for cleaning, and there are safety hazards. Content of the Utility Model

The fixture support plates on the large and small grippers are designed to be assembled. It is convenient to assemble these transmission devices by cooperating with the roller transmission mechanism, the flipping mechanism, the inner tank of the ultrasonic cleaning tank, the truss manipulator translation and lifting mechanism and the clamping mechanism, and then add a control system, so that the entire cleaning process does not require manual participation. After cleaning, the manipulator repeats the action of flipping and tilting to slowly pour out the water in the crucible and then return to the roller to flow to the next process, so as to realize full automation, which greatly reduces the difficulty of emptying and cleaning heavy crucibles.

[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0022] Refer to Figures 1 to 4 , a crucible gripping jaw device according to an embodiment of the present utility model includes a crucible 3. A large gripper 2 is provided on the right surface of the crucible 3, and a small gripper 1 is provided on the left surface of the crucible 3. The large gripper 2 includes a large fixture support plate 201, a large fixture connecting plate 202, a polyurethane large roller 203, an anti-collision column 204, and a guide post 205. The polyurethane large roller 203 is closely attached to the outer surface of the crucible 3. The inner surface of the large fixture connecting plate 202 is movably connected to the surfaces at both ends of the polyurethane large roller 203, and the inner surface of the large fixture support plate 201 is movably connected to the outer surface of the large fixture connecting plate 202. The anti-collision column 204 is fixedly connected to the outer surface of the large fixture connecting plate 202 near the end, the guide post 205 is fixedly connected to the upper surface of the anti-collision column 204, the polyurethane stop block 206 is fixedly connected to the edge position of the lower surface of the large fixture support plate 201, and the limit groove 207 is provided at the position near the edges at both ends of the large fixture support plate 201. The plate slider design on the back of the large fixture support plate 201 is detachable to facilitate replacing a more suitable tool for work, and the large fixture connecting plate 202 has a large angle at the corners to grip crucibles with different sizes.

[0023] The small gripper 1 comprises a small clamp support plate 101, a small clamp connection plate 102, a small polyurethane roller 103, and a connecting shaft 104. The small polyurethane roller 103 is in close contact with the outer surface of the crucible 3, and the small clamp connection plate 102 is flexibly connected to the ends of the small polyurethane roller 103. The connecting shaft 104 runs through the interior of the small clamp connection plate 102, and the inner surface of the small clamp support plate 101 is flexibly connected to the ends of the connecting shaft 104. The small polyurethane roller 103 is made of a material that is resistant to high temperatures, corrosion, and is highly elastic, significantly increasing its service life.

[0024] Working Principle: Force is applied to move the large and small gripping claws 2 and 1 toward the center. Limiting grooves on the large fixture connecting plate 202 constrain the angles of the large and small polyurethane rollers 203 and 103, preventing them from excessively deflecting during the flipping process. Polyurethane stoppers 206 then limit the displacement angle of the large fixture support plate 201, ensuring compatibility with crucibles 3 of varying sizes. The crucibles 3 of varying sizes are held in place by the small polyurethane rollers 103, preventing them from flipping to a certain angle and causing them to fall and be damaged.

[0025] After gripping the product, the product is lifted to a certain height, and the turning mechanism rotates the crucible 3 45 degrees and tilts it into the ultrasonic tank for cleaning. After the crucible is cleaned, the robot and the gripping and turning mechanism remove the crucible 3. After gripping the crucible 3, the turning mechanism rotates 45 degrees and tilts it to remove it from the water surface. During this process, the turning mechanism continues to tilt and pour out the water and impurities in the crucible 3. The turning mechanism flips the crucible 3 back to its original position, and then places it on the transmission roller with the opening facing upwards to flow into the next process.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
