Description

Technical Field

[0001] The utility model relates to the technical field of automatic crucible cleaning, in particular to an in-tank ultrasonic automatic crucible cleaning mechanism. Background Technique

[0002] The size of the quartz crucible is getting larger and larger. It is a glass-like vessel formed by melting high-purity quartz sand at high temperature. It is a common practice for crucible manufacturers at home and abroad to directly put it into production after a series of processing technologies. After the crucible made in this way is melted and formed, cutting fluid and other metal impurities will adhere to the surface during the processing process, and it is easy to be contaminated with oil or fingerprints during the inspection process. Although it needs to be soaked and cleaned manually, it is difficult to clean thoroughly. When put into production, it will affect the quality and qualification rate of monocrystalline silicon. At the same time, after the quartz crucible is used in a series of experiments, experimental products are likely to accumulate on the inner wall, and it needs to be cleaned before the next operation. Moreover, manual cleaning has a high labor intensity and low work efficiency. As a key component in crystal growth, not only its material specifications have a great impact on crystal growth, but the cleanliness inside the crucible directly affects the quality of one furnace or even several furnaces of crystals; (Manually use a long brush, watering while manually scrubbing the inner wall of the crucible with the brush. In this way, both ends can be cleaned thoroughly, but it is difficult to clean the middle and bottom parts. During the cleaning process, due to the large volume of the crucible, it is not easy to rotate. Only the cleaning operator can clean it by rotating around the crucible, and manual cleaning of the crucible has a high labor intensity, poor cleaning effect, and uneven cleaning).

[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 cleaning problem of large-size crucibles has also emerged. Traditional crucible cleaning requires manual use of alcohol and lint-free cloth for wiping and cleaning, with low efficiency and unclean wiping. Moreover, heavy crucibles cannot be emptied for cleaning, 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. The utility model designs an in-tank ultrasonic automatic crucible cleaning mechanism to solve the above problems. Summary of the Invention

[0015] Working principle: When in use, the crucible is conveyed from the loading port to the interior of the device through a roller drive mechanism. A combination of a motor and a speed reducer is adopted, and then chain drive is used to drive the movement of the crucible. Subsequently, the transverse movement motor drives the rotation of the transverse movement drive shaft, and then drives the rotation of the main transverse movement drive gear. Furthermore, under the guiding action of the V-shaped gear body and the transverse movement driven gear, the V-shaped rack is driven to move relatively. Since the V-shaped rack is fixed to the outer shell, the entire truss manipulator translation and lifting mechanism is driven to move horizontally on the outer wall of the V-shaped gear body, and the clamping and flipping mechanism is moved above the roller drive mechanism. Subsequently, the lifting motor drives the rotation of the lifting drive shaft, and then rotates on the lifting gear fixed to the outer wall of the lifting drive shaft. In cooperation with the chain drive installed on the outer wall of the lifting sprocket, the chain is fixedly engaged with the chain pull plate to drive the movement, thereby driving the outer wall of the follower mounting plate and the upper and lower protective covers to move up and down, further driving the cross arm to move up and down, and further driving the clamping and flipping mechanism to move up and down. Subsequently, the driving cylinder contracts its telescopic end inward, thereby driving the slider connecting plate to converge towards the middle, and then using the flipping fixture to clamp the crucible. Subsequently, the shaft body is driven to rotate under the lifting sprocket, and then drives the rotation of a plurality of meshing flipping pinions fixedly connected thereto, further driving the rotation of the main flipping gear, and then driving the rotation of the flipping gear at the lower end, and then rotating the crucible. Subsequently, the crucible is grasped and lifted above the ultrasonic tank through the above-mentioned transmission principle in cooperation with the clamping and flipping mechanism. Under the action of the flipping pinions and the flipping gears, it is grasped from the roller, lifted, rotated 90°, contacted the water surface, and then rotated 90° and slowly sank into the fixing seat in the tank to start ultrasonic cleaning. The ultrasonic tank has an inner tank and an outer tank, and the water replenishment and drainage of the two tanks are carried out separately. The drainage of the inner tank is directly discharged through the internal and external threads plus a flange. When the crucible is placed in the tank filled with water for cleaning, a part of the dirt overflows into the outer tank through the inner tank, and a part is deposited at the bottom of the inner tank and discharged through the drain port, always keeping the inner tank relatively clean, and dynamically replenishing water through a liquid level float ball; after cleaning, it is grasped, lifted, and rotated 90° to pour out the water in the crucible, lifted above the water surface and rotated 90° to completely pour out the water to reduce the weight during lifting. The truss mechanism is horizontally moved above the transmission roller to make the crucible in the same state as when being taken. 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.

[0016] (III) Beneficial effects

[0017] The utility model provides an in-tank ultrasonic automatic crucible cleaning mechanism. It has the following beneficial effects:

[0018] By setting up a roller transmission mechanism, a flipping mechanism, an ultrasonic cleaning tank tank, a truss manipulator translation and lifting mechanism, and a clamping mechanism; the truss manipulator translation and lifting mechanism is installed on both sides of the frame to provide kinetic energy to the clamping mechanism, and then cooperates with the flipping mechanism to flip and tilt the crucible into the ultrasonic tank to clean the crucible. The crucible is grabbed from the transmission roller (with the crucible mouth facing down), flipped and tilted, and placed into the left and right ultrasonic tanks (with the mouth facing up), thereby improving the cleaning efficiency. After cleaning, the manipulator repeats the flipping and tilting action to slowly pour out the water in the crucible and then return it to the roller to flow to the next process. The entire cleaning process of the utility model does not require human intervention, greatly reducing the difficulty of flipping and cleaning heavy crucibles. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] As Fig.12 shown, it is fixed to the frame through the connecting plate, the support plate. If only the tensioning mechanism is used, tooth skipping and slipping will occur. After adding the track, through the cooperation of the rollers on the roller chain and the guiding track, a smooth rolling motion can be achieved, thereby completing the positioning and guiding of the product. The guiding function of the chain guide can keep the object in a stable position during movement, avoiding deviation and shaking due to force. In addition, the chain guide can share the pressure of the object under force, making the movement of the object more stable and reliable. enabling the mechanical equipment to move along the predetermined trajectory, the chain guide can provide support and fixation for the chain, so that the chain will not deform or break under force.

[0042] As Figure 2 , Figure 9 , Figure 8 , Fig.10 and Fig.14 As shown, the truss manipulator translation and lifting mechanism 2 has the characteristics of high precision, high reliability, high speed, etc., which can enhance the stability of the operation and ensure the production efficiency. It can also work continuously for a long time in its harsh production environment. Its simple structure makes it easy to operate and maintain, greatly improving the labor productivity. The truss manipulator translation and lifting mechanism is composed of left and right assembly bodies. On the roller fixing plate of the left assembly body, a V-shaped gear is installed and fixed on the roller fixing plate through the V-shaped gear shaft. It is positioned and fixed by the guide wheel fixing plate and the guide wheel limit plate. The V-shaped gear slides in cooperation with the racks on the inner sides of the aluminum profiles of the frame. The power is transmitted to the main transverse transmission gear through the transverse movement motor and the transverse movement reducer through the transverse movement rotating shaft, and drives the entire assembly body with the transverse movement driven gear. Thus, the V-shaped rollers on the roller fixing plate slide and friction externally with the V-shaped rack installed on the frame, and the V-shaped rack meshes and drives with the transverse movement gear, improving the overall stability, being able to reduce the friction force during operation, ensuring relatively smoother operation and less noise during operation. The vertical plate and the side plate are connected by strengthening channels to install the base. A linear guide rail is assembled on the vertical plate for guiding. The linear guide rail is fixedly installed with the follower mounting plate to drive the entire mechanism to lift. The sprocket and chain method is used for transmission, and the power is transmitted through the lifting motor and the lifting reducer through the lifting transmission shaft. On the lifting transmission shaft, a lifting gear is installed and connected to the chain pull plate. Under the lifting gear, the chain is tensioned by the adjusting block and the mounting base. The follower mounting plate is fixed with a lifting switch sensing piece and a lifting switch contact piece to sense the upper and lower extreme positions and the original position of the lifting position. The cross beam and the cross arm are connected to the fixed position on the right side. The transverse movement transmission shaft extends to the right gear and transmits power on both the left and right sides through the transverse movement transmission shaft. The right origin detection plate is the original position of the manipulator returning to the origin, and the extreme position stop block is the maximum distance of the transverse movement.

[0043] As Figure 4 , Figure 5 , Figure 6As shown, in order to ensure that the crucible is completely in contact with the cleaning liquid and cleaned, the crucible is generally clamped on the cleaning rack with its opening facing upwards during cleaning. After clamping, the cleaning rack is placed in the cleaning tank to completely immerse the crucible in the cleaning liquid in the cleaning tank. At this time, the air in the crucible can be completely discharged, thereby ensuring that the crucible can be cleaned. However, when the crucible is taken out, a large amount of liquid will remain in the crucible because the crucible opening faces upwards, and the impurities cleaned are not completely discharged, resulting in incomplete cleaning and poor cleaning effect. The clamping and flipping mechanism 3 includes: a linear guide rail fixed on the cross arm The cylinder vertical plate is fixed to each side of the cross arm and locked by the cylinder vertical plate fixing blocks. The cylinder is fixed to the cylinder connecting plate by a bridge structure. The cylinder actuation generates significant force, so the cylinder connection reinforcement ribs and the cylinder connection reinforcement plate are added to enhance strength. The output end of the cylinder head is fixed to the connecting plate with a double-ear joint. The connecting plate has slots that connect to the slider connecting plate to allow for sliding movement during cylinder extension and contraction. However, the connecting plate and the slider connecting plate are not strong enough and prone to tilting. Adding reinforcement ribs effectively addresses this problem. Stop blocks act as limiters to prevent the linear guide from moving slightly under load. Using a cylinder as the power element and a linear guide as the guide does not guarantee synchronization, resulting in relative error. Gears are added to the inside of the cross arm to secure the rack and pinion to the slider connecting plate. The meshing of the rack and pinion ensures consistent synchronization during cylinder actuation. The tilting motor and reducer are fixed to the connecting plate. The tilting drive is connected to the pinion via a shaft, transmitting its rotation to the large gear one stage at a time. The involute gears mesh with each other, so error is negligible. A flip origin induction bracket is fixed on the connecting plate to install the sensor, which has a return to origin position and a limit position. The gear rotation drives the sensor contact piece to achieve detection. The large gear below is connected to the flange. The flange has a bearing that is connected to the flip fixture through a flip shaft to realize the flipping action. Finally, after clamping the product, it is lifted to a certain height and the flip mechanism rotates the crucible 45 degrees and tilts it into the ultrasonic tank. After flipping it 45 degrees, the crucible mouth faces upward and sits on the cylindrical base to start cleaning. After the crucible is cleaned, the crucible is removed by the robot and the clamping and flipping mechanism. After clamping the crucible, the flip mechanism rotates 45 degrees and tilts it to make it out of the water. During this process, the crucible continues to flip and tilt to pour out the water and impurities in the crucible. After the flip mechanism flips the crucible back to its original position, the opening faces upward and is placed on the transmission roller to flow into the next process.

[0044] like Figure 2 、 Figure 3As shown, the tank of the ultrasonic cleaning mechanism 4 is divided into an inner tank and an outer tank. The outer tank is made of stainless steel and the inner tank is made of polypropylene, which prevents direct contact between the product and the outer tank and reduces corrosion. The outer tank has positioning mounting points on the sides and bottom to secure the ultrasonic vibrating plate. After being placed into the inner tank, limit plates are installed on all sides and bottom to prevent deformation. The height difference between the two sides of the inner tank allows impurities to float to the surface and overflow into the outer tank, ensuring the cleanliness of the inner tank water. Dynamic water replenishment is also provided via a liquid level float. The bottom of the inner tank has a cylindrical base and limit plates to ensure the placement of crucibles, which can accommodate crucibles of various sizes. The inner tank drain is welded to the tank body via an inner thread. A straight outer thread passes through the outer tank and screws into the inner thread. A flange is welded to one side of the outer tank and a sealing gasket and connecting plate are added to ensure a seal, preventing the water in the inner and outer tanks from communicating with each other. The ultrasonic wave has a frequency of up to 3000 Hz. It has good directionality and strong penetrating power, which facilitates the acquisition of concentrated sound energy, which is then converted into mechanical vibration to clean the tank wall. Due to the radiated ultrasonic waves, the microbubbles in the liquid in the cleaning tank can maintain vibration under the action of ultrasonic waves, so that they are scattered into the cleaning liquid, overflow into the outer tank and discharged through the overflow port and drain port of the outer tank.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
