Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning technology, specifically to an integrated ultrasonic cleaning and drying machine for lead frame core material production. Background Technology

[0002] The core material of the lead frame is a key material constituting the main body of the lead frame. It bears multiple functions such as stabilizing the chip, conducting signals, and transferring heat. During its production process, it needs to be ultrasonically cleaned. Ultrasonic cleaning utilizes the cavitation, acceleration, and direct flow effects of ultrasound in liquids to directly and indirectly act on the liquid and contaminants, causing the contaminant layer to be dispersed, emulsified, and peeled off to achieve the purpose of cleaning. Because ultrasonic cleaning has good effects, is simple to operate, and can remove a wide range of contaminants with almost no limitations on the contaminants that can be cleaned and removed, more and more industries and enterprises are using ultrasonic cleaning machines.

[0003] Chinese Patent (Authorization Announcement No.: CN 219401422 U, Authorization Announcement Date: 2023.07.25) proposes an ultrasonic cleaning and drying integrated machine, including a housing and a drying mechanism; the housing has an open structure in the middle of its upper surface, and a cover plate is rotatably connected to the rear end of the upper surface of the housing via a rotating shaft. An inner shell is provided in the middle of the top wall of the housing, and a first solenoid valve is connected in series in the middle of the discharge pipe of the inner shell. A water inlet pipe is provided at the upper end of the outer side of the inner shell, and the water inlet pipe is connected to the water inlet hole on the surface of the inner shell. A second solenoid valve is connected in series in the middle of the water inlet pipe. Ultrasonic transducers are provided in the mounting holes on the inner side of the inner shell. An ultrasonic generator is provided at the front end of the bottom wall of the housing, and a PLC controller is provided at the lower end of the front surface of the housing. This ultrasonic cleaning and drying integrated machine reduces the working time required by the ultrasonic cleaning and drying machine, automatically lifts the cleaned items out of the cleaning water to dry the items in advance, and improves the working efficiency of the ultrasonic cleaning and drying integrated machine.

[0004] However, the device in the aforementioned patent requires loading the material to be cleaned, then cleaning it, then drying it, and finally taking out the dried material. This greatly reduces the speed of cleaning and drying. In order to improve the ultrasonic cleaning and drying speed of lead frame core material, we propose an integrated ultrasonic cleaning and drying machine for lead frame core material production.

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.

[0026] Please see Figure 1-7This utility model provides a technical solution: an ultrasonic cleaning and drying integrated machine for lead frame core material production, including a base plate 1. An ultrasonic cleaning mechanism 10, a drying mechanism 11, and a material conveying mechanism 9 are installed on the base plate 1. The material conveying mechanism 9 includes a hollow support column 12, which is fixedly installed on the base plate 1. A long rod 13 is movably installed on the hollow support column 12. A triangular support frame 14 is fixedly installed above the long rod 13. A circular protrusion 17 is fixedly installed in the middle of the upper part of the triangular support frame 14. A first positioning recess 16 is fixedly installed at the upper end of the hollow support column 12. A first positioning protrusion 15 is fixedly fitted on the long rod 13. The first positioning protrusion 15 and the first positioning recess 16 cooperate with each other. Three sets of feeding assemblies 18 are rotatably installed on the triangular support frame 14. Each feeding assembly 18 includes a support rod 19, which is rotatably connected to the triangular support frame 14. A fixed... A plurality of lower placement discs 21 are installed, and an upper placement disc 22 is set above the lower placement discs 21. The upper placement disc 22 is slidably connected to the support rod 19. A support frame 7 is fixedly installed on the triangular support frame 14, and an electric push rod 8 is fixedly installed on the support frame 7. A support arm 2 is fixedly installed on the base plate 1, and two sets of guide rollers 6 are fixedly installed on the support arm 2. A support platform 37 is fixedly installed on the base plate 1, and a drive motor 3 is fixedly installed on the support platform 37. The drive shaft of the drive motor 3 rotates through the support arm 2. A rope take-up roller 4 is fixedly fitted on the drive shaft of the drive motor 3. The rope take-up roller 4 is fixedly connected to the wire rope 5. The other end of the wire rope 5 is fixedly connected to the circular protrusion 17. The wire rope 5 and the guide rollers 6 cooperate with each other. A plurality of protrusions are fixedly installed on both the upper placement disc 22 and the lower placement disc 21. A plurality of through holes are opened on both the upper placement disc 22 and the lower placement disc 21.

[0027] In use, the upper placement disc 22 is slid upwards with the cooperation of the support rod 19. Then, the lead wire frame core material is placed on the lower placement disc 21. Next, the upper placement disc 22 is lowered, and the protrusions on both discs hold the lead wire frame core material in place. Then, with the cooperation of the hollow support column 12, the long rod 13 and the triangular support frame 14 are rotated 120 degrees until the triangular support frame 14 touches the output shaft of the electric push rod 8. Then, the drive motor 3 is started, and the drive shaft of the drive motor 3 drives the take-up roller 4 to rotate. With the cooperation of the two sets of wire rollers 6, the wire rope 5 is released from the take-up roller 4. With the cooperation of the hollow support column 12 and the long rod 13, the triangular support frame 14 moves downwards until the feeding assembly 18 containing the lead wire frame core material is placed on the ultrasonic... The ultrasonic cleaning mechanism 10 is then cleaned, and the drive motor 3 is turned off. At the same time, the operator loads the lead frame core material into the next set of feeding components 18. After cleaning, the drive motor 3 is started, and the feeding components 18 in the ultrasonic cleaning mechanism 10 are pulled out. At the same time, the output shaft of the electric push rod 8 is retracted. Then, the triangular support frame 14 is rotated. After rotating for a while, the output shaft of the electric push rod 8 is extended until the triangular support frame 14 touches the output shaft of the electric push rod 8. The rotation is then stopped. The triangular support frame 14 is then lowered. With the cooperation of the first positioning protrusion 15 and the first positioning concave block 16, the triangular support frame 14 is positioned in a suitable position. Then, the feeding components 18 containing the cleaned lead frame core material are placed into the drying mechanism 11 for drying.

[0028] The ultrasonic cleaning mechanism 10 includes a cleaning chamber 23, an ultrasonic generator 24 is fixedly installed on the cleaning chamber 23, and an ultrasonic transmitter 25 and a vibrating steel plate 26 are fixedly installed inside the cleaning chamber 23.

[0029] In use, the ultrasonic generator 24 and the ultrasonic transmitter 25 work together to emit ultrasonic waves, which are then used to ultrasonically clean the lead frame core material in the feeding assembly 18 in conjunction with the vibrating steel plate 26 and the cleaning agent.

[0030] The drying mechanism 11 includes a drying chamber 38, which is fixedly connected to the base plate 1. A hot air pipe 29 is fixedly connected to the drying chamber 38, and an air inlet pipe 30 is fixedly connected to the hot air pipe 29. A slot 31 is opened on the side of the drying chamber 38. A rotating column 35 is rotatably installed inside the drying chamber 38. A second positioning protrusion 36 is fixedly installed on the top of the rotating column 35. A second positioning recess 20 is fixedly installed at the bottom of the support rod 19. The second positioning protrusion 36 and the second positioning recess 20 cooperate with each other. The drying mechanism 11 also includes a drive motor 28. A limiting platform 27 is fixedly installed on the base plate 1. The drive motor 28 is fixedly connected to the limiting platform 27. A drive pulley 32 is fixedly mounted on the transmission shaft of the drive motor 28. A driven pulley 33 is fixedly mounted on the rotating column 35. A belt 34 is tensioned and sleeved between the drive pulley 32 and the driven pulley 33.

[0031] In use, the drive motor 28 is started, and the output shaft of the drive motor 28 drives the active pulley 32. Under the action of the belt 34, the driven pulley 33 and the rotating column 35 also begin to rotate. When the rotating column 35 rotates, the second positioning protrusion 36 and the second positioning concave block 20 cooperate with each other, so that the support rod 19 is locked on the rotating column 35, thereby driving the feeding assembly 18 to rotate. The rotation of the feeding assembly 18 is beneficial to drying the cleaned lead frame core material. At the same time, hot air is sent into the drying chamber 38 through the air inlet pipe 30 and the hot air pipe 29 to dry the cleaned lead frame core material.

[0032] Working principle: In use, the upper placement disc 22 is slid upward with the cooperation of the support rod 19, and then the lead frame core material is placed on the lower placement disc 21. Then the upper placement disc 22 is placed down, and the protrusions on the two placement discs hold the lead frame core material in place. Then, with the cooperation of the hollow support column 12, the long rod 13 and the triangular support frame 14 are rotated 120 degrees until the triangular support frame 14 touches the output shaft of the electric push rod 8. Then the drive motor 3 is started, and the drive shaft of the drive motor 3 drives the take-up roller 4 to rotate. With the cooperation of the two sets of wire rollers 6, the wire rope 5 is released from the take-up roller 4. With the cooperation of the hollow support column 12 and the long rod 13, the triangular support frame 14 moves downward until the feeding assembly 18 containing the lead frame core material is placed into the ultrasonic cleaning mechanism 10. Then the drive motor 3 is turned off.

[0033] The ultrasonic generator 24 and the ultrasonic transmitter 25 work together to emit ultrasonic waves, which are then used to ultrasonically clean the lead frame core material in the feeding assembly 18 in conjunction with the vibrating steel plate 26 and the cleaning agent. At the same time, the staff puts the lead frame core material into the next feeding assembly 18. After cleaning, the drive motor 3 is started to pull out the feeding assembly 18 in the ultrasonic cleaning mechanism 10, and the output shaft of the electric push rod 8 is retracted. Then the triangular support frame 14 is rotated. After rotating for a while, the output shaft of the electric push rod 8 is extended until the triangular support frame 14 touches the output shaft of the electric push rod 8 and then the rotation stops. Then the triangular support frame 14 is moved down. With the cooperation of the first positioning protrusion 15 and the first positioning concave block 16, the triangular support frame 14 is positioned in a suitable position. Then the feeding assembly 18 with the cleaned lead frame core material is placed in the drying mechanism 11 for drying.

[0034] Then, the drive motor 28 is started. The output shaft of the drive motor 28 drives the active pulley 32. Under the action of the belt 34, the driven pulley 33 and the rotating column 35 also start to rotate. When the rotating column 35 rotates, the second positioning protrusion 36 and the second positioning concave block 20 cooperate with each other, so that the support rod 19 is locked on the rotating column 35, thereby driving the feeding assembly 18 to rotate. The rotation of the feeding assembly 18 is conducive to drying the cleaned lead frame core material. At the same time, hot air is sent into the drying chamber 38 through the air inlet pipe 30 and the hot air pipe 29 to dry the cleaned lead frame core material.

[0035] This design enables simultaneous feeding and unloading, greatly improving the speed of ultrasonic cleaning and drying of the lead frame core material.
