Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning device technology, and specifically to an ultrasonic cleaning device for ceramic substrates. Background Technology

[0002] Ceramic substrates are functional motor packaging substrates based on ceramic materials, with alumina as the main material. Due to their excellent electrical, thermal, and mechanical properties, ceramic substrates are widely used in high-end motor devices. During storage and transportation, the substrates are prone to absorbing dust, oil, fingerprints, and other contaminants, which can directly affect electrical performance. Therefore, ceramic substrates need to be cleaned regularly.

[0003] When cleaning ceramic substrates, ultrasonic cleaners are usually used. The ultrasonic cleaner uses a high-frequency oscillation signal emitted by an ultrasonic generator, which is converted into high-frequency mechanical oscillation by a transducer and then propagated to the medium, thereby achieving the effect of cleaning the surface of the product.

[0004] However, when using an ultrasonic cleaner to vibrate and clean ceramic substrates, if hard particles are mixed into the cleaning solution or the cleaning time is too long, the continuous cavitation impact can cause cumulative damage to the surface of the ceramic substrate, resulting in alumina powder on the surface of the ceramic substrate.

[0005] When cleaning the alumina powder on the surface of the ceramic substrate, it is usually done manually by holding the ceramic substrate and rinsing the alumina powder on the surface. This process is not only laborious, but also the workers' hands come into contact with the ceramic substrate during the cleaning process. Therefore, if the ceramic substrate is not cleaned and dried properly, fingerprints or impurities may be left on the ceramic substrate. After rinsing, it needs to be dried, and impurities may also be left on the ceramic substrate during the process of moving it to the drying device. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an ultrasonic cleaning device for ceramic substrates, which solves the problem mentioned in the background art that when cleaning and rinsing the alumina on the surface of ceramic substrates and subsequently drying them, manual handling of the ceramic substrates can easily cause re-contamination of the surface.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An ultrasonic cleaning device for ceramic substrates includes an ultrasonic cleaner, a cleaning chamber, a grid-shaped placement rack, a washing and drying integrated assembly, and a substrate lifting assembly. The ultrasonic cleaner is installed inside the cleaning chamber, and vertical through slots are provided on two opposite sides of the cleaning chamber. The grid-shaped placement rack is disposed inside the cleaning chamber via a lifting adjustment assembly, and several through slots are provided at the bottom of the grid-shaped placement rack. The washing and drying integrated assembly is disposed on the side of the cleaning chamber and is used to rinse and dry the ceramic substrate. Several substrate lifting assemblies are provided on the grid-shaped placement rack to drive the ceramic substrate to reciprocate at a height within the washing and drying integrated assembly.

[0011] Furthermore, the lifting adjustment assembly includes a support cover, a reciprocating screw, a motor, and a sliding assembly. The support cover is fixedly installed at the two vertical through slots of the cleaning tank. The reciprocating screw is rotatably installed in one of the support covers, and a matching crescent-shaped slider is installed on the reciprocating screw. The motor is installed on the support cover, and the output end of the motor is coaxially connected to the reciprocating screw. The sliding assembly is disposed in the other support cover.

[0012] Furthermore, the sliding assembly includes a sliding rod and a sliding block. The sliding rod is fixedly installed inside the other support cover, the sliding block is slidably installed on the sliding rod, and the grid-shaped placement frame is fixedly installed between the sliding block and the crescent-shaped slider via a connecting rod.

[0013] Furthermore, the substrate lifting assembly includes an electric push rod, a lifting frame, and a placement plate. The electric push rod is fixedly installed on both sides of the cleaning tank, and the lifting frame is fixedly installed on the output end of the electric push rod. The placement plate is fixedly installed on the other end of the two lifting frames, and a substrate placement groove is opened at the top of the placement plate.

[0014] Furthermore, the washer-dryer assembly includes a water pump, a dryer, a conveying U-shaped tube, and an annular tube. The water pump is installed on the side of the washing tank, and its outlet is connected to a water outlet pipe. The dryer is installed on the side of the washing tank, and its air outlet is connected to an air outlet pipe.

[0015] To further protect the electric push rod when spraying water, the cleaning tank is detachably equipped with protective plates on both sides, and the electric push rod is located inside the protective plates.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an ultrasonic cleaning device for ceramic substrates, which has the following advantages:

[0018] In this invention, when cleaning ceramic substrates, several ceramic substrates are first placed in the substrate placement slot of the placement plate. Then, the lifting and adjusting component moves the grid-shaped placement rack to a position close to the ultrasonic cleaner. Then, the substrate lifting component moves several ceramic substrates into the ultrasonic cleaner for ultrasonic cleaning. After cleaning, the substrates are lifted to the washing and drying unit for spray washing to remove the alumina from the surface of the ceramic substrates and allow for subsequent drying.

[0019] Therefore, the ultrasonic cleaning device for ceramic substrates can spray and dry ceramic substrates through the cooperation between the cleaning tank, the grid-shaped placement rack, the washing and drying integrated assembly and the substrate lifting assembly. This process does not require manual contact with the ceramic substrate, which is both convenient and ensures the cleanliness of the ceramic substrate cleaning process. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 8 An ultrasonic cleaning device for ceramic substrates includes an ultrasonic cleaner 1, a cleaning chamber 2, a grid-shaped placement rack 3, a washing and drying integrated assembly, and a substrate lifting assembly. The ultrasonic cleaner 1 is installed inside the cleaning chamber 2, and vertical through slots are provided on two opposite sides of the cleaning chamber 2. The grid-shaped placement rack 3 is installed inside the cleaning chamber 2 via a lifting adjustment assembly, and several through slots are provided at the bottom of the grid-shaped placement rack 3. The washing and drying integrated assembly is installed on the side of the cleaning chamber 2 for rinsing and drying the ceramic substrate. Several substrate lifting assemblies are provided on the grid-shaped placement rack 3 for driving the ceramic substrate to reciprocate at the height of the washing and drying integrated assembly.

[0031] like Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, when cleaning the ceramic substrate, it is necessary to add that the cleaning chamber 2 has a through groove on its side, and a door is hinged to the through groove. A valve is also installed at the bottom of the cleaning chamber 2. First, open the door and place the ultrasonic cleaner 1 inside. Then, place the ceramic substrate on the placement plate 12. The bottom of the ceramic substrate matches the substrate placement groove on the placement plate 12. After placement, the ceramic substrate and the cleaning chamber 2 are moved downwards by the lifting adjustment assembly. The lifting adjustment assembly includes a support cover 4, a reciprocating screw 5, a motor 7, and a sliding assembly. The support cover 4 is fixedly installed at the two vertical through grooves of the cleaning chamber 2. The reciprocating screw 5 is rotatably installed inside one of the support covers 4, and a matching crescent slider 6 is installed on the reciprocating screw 5. It should be noted that the crescent slider 6 has a threaded groove inside that matches the thread on the outside of the reciprocating screw 5. The motor 7 is installed on the support cover 4, and the output end of the motor 7 is coaxially connected to the reciprocating screw 5. The sliding assembly is set inside the other support cover 4. The sliding assembly includes a sliding rod 8 and a sliding block 9. The sliding rod 8 is fixedly installed inside the other support cover 4, and the sliding block 9 is slidably installed on the sliding rod 8. The grid-shaped placement frame 3 is fixedly installed between the sliding block 9 and the crescent slider 6 through a connecting rod.

[0032] Specifically, the motor 7 is started, and the output end of the motor 7 drives the reciprocating screw 5 to rotate inside the support cover 4, thereby driving the crescent slider 6 to rise and fall on the reciprocating screw 5. Under the connection of the connecting rod and the grid-shaped placement frame 3, the connecting rod and the sliding block 9 at the other end move synchronously on the sliding rod 8, and the grid-shaped placement frame 3 is moved above the ultrasonic cleaner 1 and then stopped.

[0033] like Figure 3 and Figure 6 As shown, after the movement is completed, the substrate lifting assembly drives the placement plate 12 and the ceramic substrate to move down into the ultrasonic cleaner 1 for ultrasonic vibration cleaning. It should be noted that the top of the ultrasonic cleaner 1 is open. The substrate lifting assembly includes an electric push rod 10, a lifting frame 11 and a placement plate 12. Electric push rods 10 are fixedly installed on both sides of the cleaning box 2. The output end of the electric push rod 10 is fixedly installed with a lifting frame 11. The placement plate 12 is fixedly installed on the other end of the two lifting frames 11, and a substrate placement groove is opened at the top of the placement plate 12.

[0034] Specifically, the electric push rod 10 is started, which moves the placement plate 12 and the ceramic substrate on the placement plate 12 down into the ultrasonic cleaner 1. After cleaning, it is lifted up, and then the motor 7 is started again, which moves the grid-shaped placement rack 3 and the ceramic substrate up to the top of the cleaning tank 2.

[0035] like Figure 4As shown, after the ceramic substrate is moved to the top of the cleaning tank 2, the surface of the ceramic substrate can be rinsed by the washing and drying integrated assembly. The washing and drying integrated assembly includes a water pump 13, a dryer 14, a conveying U-shaped tube and an annular tube 16. The water pump 13 is installed on the side of the cleaning tank 2, and the outlet of the water pump 13 is connected to the water outlet pipe 19. The dryer 14 is installed on the side of the cleaning tank 2, and the air outlet of the dryer 14 is connected to the air outlet pipe 18. The two ends of the conveying U-shaped tube 15 pass through the side of the cleaning tank 2, and the other ends of the air outlet pipe 18 and the water outlet pipe 19 are connected to the bottom end of the conveying U-shaped tube 15. The annular tube 16 is located inside the cleaning tank 2, and the two ends of the conveying U-shaped tube 15 are connected to the two sides of the annular tube 16.

[0036] Specifically, when the ceramic substrate is moved to the annular pipe 16, the water pump 13 is connected to the water tank and then started. The water pump 13 delivers water through the outlet pipe 19 into the conveying U-shaped pipe, and then into the annular pipe 16. It should be noted that the annular pipe 16 has nozzles on its four side walls. After the water is sprayed out, the electric push rods 10 can be activated sequentially, lifting the ceramic substrates one by one for spraying. This ensures more uniform spraying and cleaning of each ceramic substrate surface. Protective plates 17 are detachably installed on both sides of box 2, and electric push rods 10 are located inside the protective plates 17 to prevent water from spraying onto the electric push rods 10. After spraying, the dryer 14 is started. The dryer 14 delivers warm air through the air outlet pipe 18 to the conveying U-shaped pipe 15, and then into the annular pipe 16. Similarly, the surface of the ceramic substrate is dried in sequence. It should be noted that valves are installed on both the air outlet pipe 18 and the water outlet pipe 19. When air is discharged, the valve of the water outlet pipe 19 is closed, and when water is discharged, the valve of the air outlet pipe 18 is closed.

[0037] Furthermore, when spraying water, the ultrasonic cleaner 1 can be taken out, and the sprayed water falls into the cleaning tank 2. Subsequently, the valve at the bottom of the cleaning tank 2 can be opened to allow it to flow out. The motor 7 and the electric push rod 10 transmit operation instructions to the actuator through wireless signal transmission. The remote control sends coded signals, the control module receives the signals and decodes them into electrical signals, and the electrical signals drive the circuit (such as a relay or PLC) to control the operation of the motor 7 and the electric push rod 10.

[0038] Working principle: During the cleaning process, the ultrasonic cleaner 1 is first placed inside the ultrasonic cleaner 1, and then the ceramic substrate is placed on the placement plate 12. Then, the motor 7 is started. The output end of the motor 7 drives the reciprocating screw 5 to rotate inside the support cover 4, thereby driving the crescent slider 6 to rise and fall on the reciprocating screw 5. Under the connection of the connecting rod and the grid-shaped placement frame 3, the connecting rod and the sliding block 9 at the other end move synchronously on the sliding rod 8. After the grid-shaped placement frame 3 is moved above the ultrasonic cleaner 1, it stops. Then, the electric push rod 10 is started. The electric push rod 10 drives the placement plate 12 and the ceramic substrate on the placement plate 12 to move down into the ultrasonic cleaner 1. After cleaning, it is lifted up. Then, the motor 7 is started again, driving the grid-shaped placement frame 3 and the ceramic substrate to move up to the top of the cleaning tank 2.

[0039] After the movement is completed, first connect the water pump 13 to the water tank and start the water pump 13. The water pump 13 delivers water to the conveying U-shaped pipe through the water outlet pipe 19, and then into the annular pipe 16. After the water is sprayed out, start the electric push rod 10 in sequence, and lift the ceramic substrate in sequence through the electric push rod 10, and spray it in sequence. After the spraying is completed, start the dryer 14. The dryer 14 delivers warm air to the conveying U-shaped pipe 15 through the air outlet pipe 18, and then into the annular pipe 16. Similarly, dry the surface of the ceramic substrate in sequence.
