Abstract
Description
Technical Field
[0001] This invention relates to the field of fixture cleaning technology, specifically a multifunctional automatic fixture cleaning device. Background Technology
[0002] With the rapid development of high-end fields such as power electronics, new energy vehicles, and aerospace, unprecedented demands have been placed on the performance and reliability of power semiconductor devices. Aluminum nitride ceramics, with their extremely high thermal conductivity and excellent electrical insulation properties, occupy an important position in AMB / DCB substrates. Laser cutting and drilling are essential precision machining processes during their manufacturing. However, laser processing can leave high-temperature molten residues and a blackened layer due to localized carbonization on the substrate. These slag and carbide residues pose serious quality risks. Their presence significantly reduces the cleanliness of the ceramic surface and damages the insulation performance of the substrate. More seriously, under the high voltage and high temperature conditions during subsequent device packaging and operation, these conductive or semi-conductive residues can easily induce creepage, forming leakage current paths on the insulating surface. This can ultimately lead to insulation breakdown failure, severely compromising the reliability, lifespan, and even safety of the final power module product.
[0003] Currently, the industry still largely relies on traditional methods for cleaning surface contamination on such precision ceramic carrier plates. The main methods include manual cleaning and simple mechanical cleaning. However, manual cleaning depends on the operator's experience and sense of responsibility; the cleaning force and uniformity are difficult to control precisely, and it often falls short of effectively removing firmly adhered high-temperature molten slag and carbides embedded in micropores, failing to achieve thorough removal.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example: Figures 1-9As shown, this invention provides a technical solution for a multifunctional automatic cleaning device for fixtures. This device includes a conveying platform 1, a linear drive unit 2 mounted above the conveying platform 1, a lifting unit 3 mounted on the linear drive unit 2, a support plate 11 at one end of the conveying platform 1, and a cleaning basket 4 placed on the support plate 11. An acid-alkali washing tank 5 and an ultrasonic washing tank 6 are sequentially arranged inside the conveying platform 1. A concentration detection element 7 is installed inside the acid-alkali washing tank 5. The acid-alkali washing tank 5 is connected to a first replenishment tank 8, and the ultrasonic washing tank 6 is connected to a second replenishment tank 9. The conveying platform 1 supports the entire device and has good strength. The acid-alkali washing tank 5, the first replenishment tank 8, the ultrasonic washing tank 6, and the second replenishment tank 9 are sequentially placed inside the conveying platform 1. The solution in the acid-alkali washing tank 5... The ultrasonic cleaning tank 6 reacts with residues on the carrier plate, removing even stubborn residues through chemical reaction. It cleans the carrier plate using ultrasonic waves, not only removing residual chemical solutions but also further removing impurities. The first replenishment tank 8 replenishes the solution in the acid-alkali cleaning tank 5, preventing insufficient solution concentration from affecting the cleaning effect. The second replenishment tank 9 replaces the pure water in the ultrasonic cleaning tank 6, preventing the concentration of chemical solutions in the pure water from increasing during prolonged cleaning and causing secondary contamination of the carrier plate. Different chemical substances can be selected for cleaning depending on the fixture, and the concentration in the acid-alkali cleaning tank 5 can be adjusted as needed. Furthermore, depending on the cleaning steps… The system can also add reaction tanks within the conveying platform 1 to accommodate various cleaning methods. With the cooperation of the linear drive unit 2 and the lifting unit 3, the cleaning basket 4 can be moved to any position within the conveying platform 1, achieving precise and rapid movement. This significantly reduces the time spent on movement during the cleaning process, ensuring high cleaning efficiency. The cleaning basket 4 is initially placed on the pallet 11. When cleaning the carrier plates is required, multiple carrier plates are placed into the cleaning basket 4. Then, using the linear drive unit 2 and the lifting unit 3, the cleaning basket 4 is quickly and accurately placed into the acid-alkali washing tank 5. After a period of reaction, the residue on the carrier plates is completely removed. The basket is then moved again with the cooperation of the linear drive unit 2 and the lifting unit 3. The carrier plate undergoes a second cleaning in the ultrasonic cleaning tank 6, followed by drying or removal to complete the cleaning process. During the cleaning process, the concentration detection device 7 in the acid-alkali cleaning tank 5 can detect changes in concentration in real time. When the concentration is too low or too high, it will alert the staff and add the solution from the first replenishment tank 8 into the acid-alkali cleaning tank 5 to adjust the concentration. After the carrier plate is loaded into the cleaning basket, it is first moved to the acid-alkali cleaning tank for chemical deslagging. A suitable solution is selected based on the main residues on the carrier plate to react with it and achieve chemical deslagging. Then, it is moved into the ultrasonic cleaning tank, where ultrasonic waves are used to physically remove residues from the carrier plate. Chemical polishing and drying steps can also be added as needed to achieve multi-functional cleaning of the fixture.
[0019] A shelf 12 is installed on the top of the conveying platform 1. A linear drive unit 2 is fixedly installed on the shelf 12. A lead screw 21 is installed inside the linear drive unit 2. One end of the lead screw 21 is connected to a servo motor 22. A lifting unit 3 is installed on the lead screw 21. An electromagnet 31 is installed at the bottom of the lifting unit 3. The shelf 12 is used to fix the linear drive unit 2 to prevent it from being displaced due to vibration during operation, which would cause the cleaning basket 4 to be misaligned during transportation and unable to move to the accurate position, thus affecting the efficiency of the carrier plate cleaning. The servo motor 22 drives the lead screw 21 to rotate, ensuring the stable rotation of the lead screw 21. The lifting unit 3 is sleeved on the lead screw 21, and the lead screw 21 needs to have sufficient strength and be difficult to bend. The electromagnet 31 is a key part for connecting the cleaning basket 4. The electromagnet 31 grips and releases the cleaning basket 4 by turning the electromagnet 31 on and off. When the electromagnet 31 attracts the cleaning basket 4, it has a gripping force to ensure that the cleaning basket 4 is lifted with sufficient stability.
[0020] The cleaning basket 4 has openings 41 evenly distributed on its side walls. A filter screen 42 is located at the bottom of the cleaning basket 4. A baffle 43 is located inside the cleaning basket 4. Limiting posts 44 are symmetrically arranged on the outer side of the cleaning basket 4. A limiting plate 45 is located on the same side as one of the limiting posts 44. A straight groove 4501 is formed on the limiting plate 45, and sector teeth 4502 are located at the bottom of the limiting plate 45. A rotating plate 46 is located above the baffle 44. The rotating plate 46 is fixed to the cleaning basket 4 on both sides by connecting posts 4601. Insertion points are located within the connecting posts 4601. Hole 4602, a magnetic suction component 47 is fixedly installed on the top of the cleaning basket 4; the size of the opening 41 on the side wall of the cleaning basket 4 is much smaller than the carrier plate, only allowing liquid to pass through, so there is no possibility of the carrier plate being partially stuck in the opening 41 and causing damage to the carrier plate. The mesh opening of the filter screen 42 at the bottom of the cleaning basket 4 is smaller than the opening 41, which can collect larger residues and other impurities that fall off after the chemical reaction between the baffle 43 and the filter screen 42, avoiding contamination of the acid and alkali washing tank 5; there are also some filters on the baffle 43. The filter holes are relatively large, allowing most of the residue to enter the space below the baffle 43, preventing the residue from re-adhering to the carrier plate. The limiting posts 44 on the outside of the cleaning basket 4 mainly serve to position and fix it, ensuring that the cleaning basket 4 moves to the designated position each time. The carrier plates placed in the cleaning basket 4 are all above the baffle 44, and the rotating plate 46 is initially in a vertical state. Therefore, the carrier plates are distributed on both sides of the rotating plate 46 to ensure that the carrier plates in the cleaning basket 4 are evenly distributed, avoiding the situation where the middle is higher than the periphery when the carrier plates are piled up, making it difficult to clean the carrier plates that are pressed in the middle. The cleaning basket 4 attracts the electromagnet 31 through the magnetic suction part 47 at the top, ensuring that the cleaning basket 4 can be grabbed by the lifting part. Since the solution in the acid and alkali washing tank 5 has a certain degree of corrosiveness, the material of the cleaning basket 4 needs to have sufficient corrosion resistance. When the cleaning basket 4 is placed in the acid and alkali washing tank 5, the liquid level of the solution is lower than the height of the magnetic suction part 47, so the magnetic suction part 47 will not come into contact with the acid and alkali solution, thus affecting the performance of the magnetic suction part 47.
[0021] The acid-alkali washing tank 5 is equipped with a partition 51, on which an electric fan 5101 is mounted. A first drain pipe 5102 connecting the acid-alkali washing tank 5 to the outside is also provided on the partition 51. Below the partition 51 is a secondary chamber 52, which houses a motor 5201. The output of the motor 5201 is connected to the electric fan 5101 and a pulley 5202. The other end of the pulley 5202 is equipped with a rotating shaft 5203, the top of which has a first bevel tooth 5204. The partition 51 divides the acid-alkali washing tank 5 into two areas: the upper part is filled with the cleaning solution, and the lower part is isolated from it and houses the transmission mechanism that drives the cleaning basket 4 to swing. The electric fan 5101 is located within the acid-alkali washing tank. At the center of the bottom of tank 5, a motor 5201 drives the fan 5101. When the fan 5101 rotates, it agitates the liquid in the acid-alkali washing tank 5. This not only causes the highly concentrated solution deposited at the bottom of the tank to flow upward, but also generates a certain impact force, which can wash away the residue on the surface of the carrier plate to a certain extent, effectively improving the cleaning efficiency. The output end of the motor 5202 is also connected to a pulley 5202. Through the pulley 5202, the power of the motor 5201 can be transmitted to the rotating shaft 5203 fixed outside the acid-alkali washing tank 5. This prevents the pulley 5202 and the rotating shaft 5203 from contacting the acid-alkali solution, which would cause corrosion of these components and affect their service life.
[0022] The outer wall of the acid-alkali washing tank 5 is also equipped with a circulating filter. The circulating filter continuously filters the solution in the acid-alkali washing tank 5. During the circulation filtration process, the solution flows continuously, which allows the replenishing solution that has just entered the acid-alkali washing tank 5 to quickly mix with the original solution, so that the concentration of the solution is consistent throughout. Under the action of the electric fan 5101, impurities deposited at the bottom participate in the circulation filtration and are discharged by the circulating filter. In addition to filtering out impurities generated by chemical reactions inside the acid-alkali washing tank 5, the circulating filter also removes dust and other influencing substances that may fall into the acid-alkali washing tank 5 from the outside. Since the acid-alkali washing tank 5 has a certain degree of corrosiveness, the electric fan 5101 located at the bottom of the acid-alkali washing tank 5 can be made of corrosion-resistant NPP material, which can improve the service life of the electric fan 5101.
[0023] The acid-alkali washing tank 5 has a connecting ring 53 on its outer wall, and the rotating shaft 5203 is fixed by the connecting ring 53. The top of the inner wall of the acid-alkali washing tank 5 has symmetrical limit grooves 54. The acid-alkali washing tank 5 has a through hole 55 on the side near the rotating shaft 5203. A retaining ring 5501 is provided in the middle of the through hole 55. A driving tooth 56 is provided in the through hole 55. One end of the driving tooth 56 has a second bevel tooth 5601. The other end of the driving tooth 56 has a first telescopic groove 5602. An annular groove 5603 is provided in the middle of the driving tooth 56. A first spring 5603 is provided in the first telescopic groove 5602. A driving block 5604 is embedded in the first telescopic groove 5602. The driving block 5604 has a second spring 5603 on its upper and lower sides. A slope 5605 has a driven tooth 57 below the driving tooth 56. The driven tooth 57 has a second telescopic groove 5701, a second spring 5702, and a pin 5703 embedded within it. A concentration detection element 6 is installed on the inner wall of the acid-alkali washing tank 5, positioned above the partition 51. A connecting ring 53 is used to fix an externally mounted rotating shaft 5203. The first bevel tooth 5204 on the rotating shaft 5203 engages with the second bevel tooth 5601, thus enabling the driving tooth 56 to rotate via the rotating shaft 5203. The driving tooth 56, through the engagement of a retaining ring 5501 and an annular groove 5603, not only... The position of the drive gear 56 is fixed, which also has a sealing effect to prevent the liquid in the acid and alkali washing tank 5 from leaking along the through hole 55. The drive block 5604 on the drive gear 56 is inserted into the straight groove 4501, and the two sides of the drive block 5604 are in close contact with the side wall of the straight groove 4501. When the drive gear 56 rotates, the drive block 5604 can only move within the straight groove 4501 and cannot rotate. Therefore, the rotation of the drive gear 56 will cause the limiting plate 45 to swing back and forth from side to side, which in turn will drive the entire washing basket 4 to swing. During the swinging process of the washing basket 4, the carrier plate placed inside will also move irregularly, so that all parts of the carrier plate are in contact with the acid and alkali solution. Contact ensures thorough cleaning; while the limiting plate 45 swings, the lower sector tooth 4502 rotates, and the sector tooth 4502 meshes with the driven tooth 57 below, so the driven tooth 57 also rotates. When the cleaning basket 4 is placed in the acid and alkali washing tank 5, the pin 5703 on the driven tooth 57 will be inserted into the insertion hole 4602 of the rotating plate 46. Then the rotation of the driven tooth 57 will drive the rotating plate 46 to reciprocate. The rotation of the rotating plate 46 can expose the carrier plate pressed at the bottom, and at the same time, it can also allow the residues hidden in the gaps between the carrier plates that cannot fall down to fall smoothly. This not only further realizes the contact between the carrier plate and the acid and alkali solution, but also improves the cleaning effect of the carrier plate.
[0024] The ultrasonic cleaning tank 6 has symmetrically arranged second limiting grooves 61 on the top of its inner wall, a sound wave generator 62 at the bottom, and a second drain pipe 63 at the bottom. A first replenishment tank 8 is located between the acid / alkali cleaning tank 5 and the ultrasonic cleaning tank 6. A first water inlet pipe 81 is located at the bottom of the first replenishment tank 8 and connects to the acid / alkali cleaning tank 5. A second replenishment tank 9 is located on one side of the ultrasonic cleaning tank 6. A second water inlet pipe 92 is located at the bottom of the second replenishment tank 8 and connects to the ultrasonic cleaning tank 6. The tops of the first replenishment tank 8 and the second replenishment tank 9 are sealed with sealing caps 82. The ultrasonic cleaning tank 6 is... The cleaning basket 4 is fixed by the cooperation of the limiting post 44 and the second limiting groove 61. The ultrasonic waves output by the sound wave generator 62 can thoroughly remove the impurities and chemical substances attached to the surface of the carrier plate and the previous step. The outer wall of the ultrasonic cleaning tank 6 is also equipped with a circulating filter. During the circulating filtration process, pure water is continuously supplied into the ultrasonic cleaning tank 6, while an equal amount of wastewater is discharged. While keeping the liquid level in the ultrasonic cleaning tank 6 unchanged, the residue of impurities is reduced, and the ultrasonic cleaning tank 6 is self-cleaning. In order to prevent the liquid in the first replenishment tank 8 and the second replenishment tank 9 from being contaminated, the former is sealed by the sealing cover 82.
[0025] Working principle of the invention: First, the carrier plates to be cleaned are collected and placed into the cleaning basket 4 on the tray 11. Then, the lifting unit 3 moves down and the electromagnet 31 is energized. The electromagnet 31 tightly attracts the magnetic suction piece 47 on the cleaning basket 4, completing the gripping of the cleaning basket 4. Then, with the cooperation of the linear drive unit 2 and the lifting unit 3, the limiting posts 44 on both sides of the cleaning basket 4 are embedded into the limiting grooves 54, and the cleaning basket 4 is accurately placed into the acid-alkali washing tank 5. Then, the motor 5201 is started. When the electric fan 5101 driven by the motor 5201 rotates, it can agitate the liquid in the acid-alkali washing tank 5. This not only allows the high-concentration solution deposited at the bottom of the tank to flow upward, but also produces... The motor 5202 generates a certain impact force, which can wash away the residue on the surface of the carrier plate to a certain extent, effectively improving the cleaning efficiency. The output end of the motor 5202 is also connected to a pulley 5202. Through the pulley 5202, the power of the motor 5201 can be transmitted to the rotating shaft 5203 fixed outside the acid and alkali washing tank 5. The rotating shaft 5203 can drive the drive gear 56 to rotate. The drive gear 56, through the cooperation of the retaining ring 5501 and the annular groove 5603, can not only fix the position of the drive gear 56, but also play a sealing role to prevent the liquid in the acid and alkali washing tank 5 from leaking along the through hole 55. The drive block 560 on the drive gear 56... 4. Insert the drive block 5604 into the straight groove 4501. The length of the straight groove 4501 is equal to the diameter of the circumference of the drive block 5604. The drive block 5604 is in close contact with the sidewalls of the straight groove 4501 on both sides. When the drive tooth 56 rotates, the drive block 5604 can only move within the straight groove 4501 and cannot rotate. Therefore, the rotation of the drive tooth 56 will push the sidewalls of the straight groove 4501, causing the limiting plate 45 to move laterally. This causes the limiting plate 45 to swing back and forth, which in turn causes the entire cleaning basket 4 to swing. During the swinging process of the cleaning basket 4, the carrier plate placed inside will also move irregularly, so that all parts of the carrier plate come into contact with the acid and alkali solutions. The contact ensures thorough cleaning; while the limiting plate 45 swings, the lower sector tooth 4502 rotates, and the sector tooth 4502 meshes with the driven tooth 57 below, so the driven tooth 57 also rotates. When the cleaning basket 4 is placed in the acid and alkali washing tank 5, the pin 5703 on the driven tooth 57 will be inserted into the insertion hole 4602 of the rotating plate 46. Then the rotation of the driven tooth 57 will drive the rotating plate 46 to reciprocate. The rotation of the rotating plate 46 can expose the carrier plate at the bottom, and at the same time, it can also allow the residues hidden in the gaps between the carrier plates that cannot fall to fall smoothly. This not only further realizes the contact between the carrier plate and the acid and alkali solution, but also improves the cleaning effect of the carrier plate.
[0026] The solution in the acid-alkali washing tank 5 undergoes continuous chemical reactions, causing its concentration to decrease. This decrease in concentration affects the subsequent cleaning effect. The concentration detection device 7 in the acid-alkali washing tank 5 can detect the concentration change in real time. When the concentration is too low, the first water inlet pipe 81 can be opened to introduce a higher concentration acid-alkali solution from the first replenishment tank 8 into the acid-alkali washing tank 5. Under the action of the electric fan 5101, the solution is fully neutralized, and the concentration is basically consistent throughout. Then, the first drainage channel 5102 is opened to drain part of the solution, so that the liquid level in the acid-alkali washing tank 5 remains constant.
[0027] After leaving the acid and alkali washing tank 5, the cleaning basket 4 enters the ultrasonic washing tank 6, where the carrier plate is further cleaned by ultrasonic waves. This thoroughly removes impurities and chemicals adhering to the surface of the carrier plate from the previous step, thus completing the cleaning of the carrier plate.
[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
