Description

Technical Field

[0001] This utility model belongs to the field of chip substrate cleaning technology, specifically relating to an ultrasonic ceramic sheet cleaning device with a waste liquid filtration system. Background Technology

[0002] In the manufacturing of chips in various fields such as automotive-grade power modules, base station power amplifier chips, and medical implantable electronics, high heat dissipation ceramic sheets are required as chip substrates. During the production and cutting process of ceramic substrates, some cutting and drilling particles will remain. These particles can easily cause short circuits in chip circuits and block holes, reducing heat dissipation. Therefore, ultrasonic cleaning equipment is required for cleaning, and the waste liquid after cleaning needs to be filtered before it can be discharged.

[0003] The patent specification with announcement number CN210450092U discloses a barium titanate ceramic substrate cleaning device, including a box body. A cleaning tank is fixedly installed on the left side inside the box body. A cleaning basket is movably installed inside the cleaning tank. A transducer is fixedly installed on the lower outer surface of the cleaning tank inside the box body. An ultrasonic generator is fixedly installed inside the box body below the cleaning tank. A connecting pipe is fixedly connected to the right outer surface of the cleaning tank. A filter is fixedly installed on the middle outer surface of the connecting pipe. In use, this cleaning device delivers the cleaning solution from the cleaning tank to the filter via a connecting pipe, thereby cleaning the ceramic substrate and filtering the cleaning solution. However, this technical solution has a drawback: the filter uses a filter element with an activated carbon layer and an activated silica sand layer to filter the cleaning solution. Because the internal structure of the filter is fixed, the number of filter elements that can be installed is also fixed. Therefore, when cleaning large batches of ceramic substrates, there is a need to interrupt the cleaning process to replace the filter elements, thus prolonging the cleaning time and reducing cleaning efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this utility model is to provide an ultrasonic ceramic disc cleaning device with a waste liquid filtration system. The technical problem to be solved is as follows: Existing ultrasonic ceramic disc cleaning devices require the filter element to be replaced midway through use, which reduces the cleaning efficiency.

[0006] The objective of this utility model can be achieved through the following technical solutions: An ultrasonic ceramic disc cleaning device with a waste liquid filtration system includes a housing, a cleaning chamber installed on one side of the top of the housing, a transducer assembly installed at the bottom of the cleaning chamber, two ultrasonic generators installed on one side of the bottom of the housing, an overflow trough provided on one side of the top of the cleaning chamber, and a filtration mechanism installed between one side of the bottom of the cleaning chamber and the housing. The filtration mechanism has multiple filter elements detachably connected to its middle section, and the number of filter elements installed in the filtration mechanism is adjustable.

[0007] As a further embodiment of this utility model: an inlet pipe is installed on one side of the top of the cleaning chamber, an inlet valve is installed through the inlet pipe and penetrates the box body, a transducer chamber is provided in the middle of the bottom of the cleaning chamber, the transducer assembly is installed inside the transducer chamber, and a bracket is placed on the top of the cleaning chamber.

[0008] As a further embodiment of this utility model: an overflow port is provided on one side of the top of the cleaning chamber, the overflow port is connected to the overflow trough, and an overflow pipe is installed on one side of the bottom of the overflow trough.

[0009] As a further embodiment of this utility model: a support frame is provided on the inner side of the bottom of the box, and a side rod is fixedly connected to one side of the middle part of the support frame. The filtration mechanism also includes a top clamping plate fixedly connected to the bottom of the side rod. A liquid passage pipe is installed between the top of the top clamping plate and the cleaning chamber. A liquid control valve is installed on the top of the liquid passage pipe. Locking rods are installed on both sides of the top clamping plate. A bottom clamping plate is installed between the bottom of the two locking rods. Each filter element is vertically inserted and installed between the top clamping plate and the bottom clamping plate. Drain pipes are installed on both sides of the bottom surface of the bottom clamping plate. A locking nut is installed between the bottom of the locking rod and the bottom clamping plate.

[0010] As a further embodiment of this utility model: the filter element includes a filter frame, the filter frame is provided with a filter element chamber, an inner ring block is fixedly connected to the top of the filter frame and an outer ring block is fixedly connected to the bottom, and a sealing ring is installed on the outer peripheral side of the inner ring block.

[0011] As a further embodiment of this utility model: two side doors are installed on the side of the housing near the filter mechanism, and a handle is provided in the middle of the side door.

[0012] The beneficial effects of this utility model are: By installing a cleaning chamber at the top of the housing and a filtration mechanism in the middle of the housing, multiple filter elements with sealing rings are vertically inserted between the top and bottom clamps of the filtration mechanism. The bottom clamp can be removed and installed using a locking nut. The housing also has two side doors on one side of the filtration mechanism for easy opening and closing. The technical advantages are that, firstly, operators can easily control the number of filter elements installed in the filtration mechanism by opening the side doors and loosening the locking nuts, and replace the filter elements with new ones. This ensures that the filter elements remain clean during each filtration of the cleaning solution, thereby improving the filtration effect. Furthermore, because the number of installed filter elements is related to the... The amount of cleaning solution to be filtered must be appropriate to avoid wasting filter elements. On the other hand, when there are a large number of ceramic substrates to be cleaned in a single batch, the filtration effect of the filtration mechanism can be maintained throughout the filtration process by adding multiple filter elements. This avoids the need to interrupt the cleaning process for filter element replacement due to the deterioration of filter element performance, thus maintaining the cleaning efficiency when cleaning large batches of ceramic substrates. In addition, the overflow trough installed on one side of the top of the cleaning chamber can also accommodate the frequent replacement of cleaning solution when cleaning large batches of ceramic substrates, preventing cleaning solution from overflowing and sliding down to the ultrasonic generator at the bottom of the chamber during the replacement process, thus maintaining the safety of the equipment.

[0016] 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 scope of protection of the present utility model.

[0017] like Figures 1 to 7 As shown, an ultrasonic ceramic disc cleaning device with a waste liquid filtration system includes a housing 1, a cleaning chamber 2 installed on one side of the top of the housing 1, a transducer assembly 3 installed at the bottom inside the cleaning chamber 2, two ultrasonic generators 4 installed on one side of the bottom of the housing 1, an overflow trough 5 provided on one side of the top of the cleaning chamber 2, and a filter mechanism 6 installed between the bottom of the cleaning chamber 2 and the housing 1. Multiple filter elements 61 are detachably connected in the middle of the filter mechanism 6, and the number of filter elements 61 installed in the filter mechanism 6 is adjustable. It should be noted that a support frame 7 is installed on the inner side of the bottom of the box 1 (see...). Figure 3 Two ultrasonic generators 4 are installed at the bottom of the support frame 7. Six heat dissipation vents 8 are opened on both sides of the housing 1 at the same installation height as the ultrasonic generators 4 to provide auxiliary heat dissipation for the operation of the ultrasonic generators 4. A controller 9 is set on one side of the top of the housing 1. The controller 9 includes start / stop control buttons and timer buttons for the ultrasonic generators 4. The two ultrasonic generators 4 are electrically connected to the transducer group 3. The controller 9 is used to control the operating status of the ultrasonic generators 4. Four casters 10 are installed at the corners of the bottom perimeter of the housing 1 for easy movement of the housing 1. In addition, the top of the cleaning chamber 2 is covered with an end cap when not in use.

[0018] like Figures 1 to 4 As shown, an inlet pipe 11 is installed on one side of the top of the cleaning chamber 2. An inlet valve 12 is installed through the outside of the box body 1 through the inlet pipe 11. A transducer chamber 13 is set in the middle of the bottom of the cleaning chamber 2. The transducer group 3 is installed inside the transducer chamber 13. A bracket 14 is placed on the top of the cleaning chamber 2. It should be noted that the purpose of installing the transducer chamber 13 inside the cleaning chamber 2 and installing each transducer of the transducer group 3 on the top surface inside the transducer chamber 13 is to reduce the distance between the cleaning fluid and the transducers, thereby improving the vibration cleaning effect of the transducer group 3. Specifically, the inlet valve 12 is opened to inject the cleaning fluid into the cleaning chamber 2 through the inlet pipe 11. Then, the controller 9 is operated to start the ultrasonic generator 4. The ultrasonic generator 4 then converts the conventional AC frequency into a high frequency electrical signal. Each transducer of the transducer group 3, which is electrically connected to it, converts the high frequency electrical signal into a high frequency vibration of the same frequency. This vibration passes through the top plate of the transducer chamber 13 and causes the cleaning fluid to resonate, performing ultrasonic vibration cleaning on the ceramic substrate placed on the support 14. In addition, the support 14 is used to place the ceramic substrate clamp.

[0019] An overflow port 15 is provided on one side of the top of the cleaning chamber 2. The overflow port 15 is connected to the overflow tank 5. An overflow pipe 16 is installed on one side of the bottom of the overflow tank 5. That is, when the cleaning fluid is injected into the cleaning chamber 2 through the liquid inlet pipe 11, if the amount injected is large, the cleaning fluid will enter the overflow tank 5 through the strip-shaped overflow port 15 and then be discharged through the overflow pipe 16. This avoids accidental overflow when adding cleaning fluid and prevents it from flowing to the ultrasonic generator 4 at the bottom, thus improving the safety of use.

[0020] like Figures 5 to 7 As shown, a side rod 17 is fixedly connected to one side of the middle part of the support frame 7. The filter mechanism 6 also includes a top clamping plate 62 fixedly connected to the bottom of the side rod 17. A liquid pipe 63 is installed between the top of the top clamping plate 62 and the cleaning chamber 2. A liquid control valve 64 is installed at the top of the liquid pipe 63. Locking rods 65 are installed on both sides of the top clamping plate 62. A bottom clamping plate 66 is installed between the bottom of the two locking rods 65. Each filter element 61 is installed between the top clamping plate 62 and the bottom clamping plate 66. Drain pipes 67 are installed on both sides of the bottom surface of the bottom clamping plate 66. A locking nut 68 is installed between the bottom of the locking rod 65 and the bottom clamping plate 66. The filter element 61 includes a filter frame 611, a filter element chamber 612 is provided inside the filter frame 611, an inner ring block 613 is fixedly connected to the top of the filter frame 611, and an outer ring block 614 is fixedly connected to the bottom of the filter frame 611. A sealing ring 615 is installed on the outer peripheral side of the inner ring block 613. Two side doors 18 are provided on one side of the box body 1 (see Figure 2 A handle 19 is provided in the middle of the side door 18. The side door 18 is close to the filter mechanism 6, which makes it convenient to inspect the filter mechanism 6 and replace the filter element in the filter element 61. It should be noted that the filter element 61 near the top clamping plate 62 and the bottom clamping plate 66 is inserted into the clamping plate on the adjacent side. The bottom of the liquid pipe 63 is connected to the top filter element 61, and the drain pipe 67 is connected to the bottom filter element 61, thus forming a flow path for the cleaning liquid. After cleaning, the operator can open the liquid control valve 64 to filter the cleaning liquid through the filter mechanism 6. Preferably, the outer end of the drain pipe 67 can be connected to a liquid pump for active liquid extraction. The active liquid extraction needs to control the extraction rate so that the filter element 61 can perform sufficient filtration. The filter frames 611 inside the filter element 61 are stacked and interlocked. The inner ring blocks 613 and outer ring blocks 614 at the bottom and top of the filter frame 611 can fit into each other in size. A sealing ring 615 is installed on the outside of the inner ring block 613. Then, two adjacent filter frames 611 can be docked after the filter element is inserted into the filter element chamber 612. When docking, the inner ring block 613 of one filter frame 611 is inserted into the inner side of the outer ring block 614 of another filter frame 611, and the docking surface is sealed by the sealing ring 615. This realizes the function of adjusting and controlling the number of filter elements installed in the filter mechanism 6. Specifically, before cleaning the ceramic substrate, the staff can estimate the amount of cleaning solution to be filtered, then open the side door 18 through the handle 19, remove the two locking nuts 68 at the bottom of the filter mechanism 6, then determine the number of nested layers of the filter element 61 according to the number of filter elements required for this cleaning solution, and perform the corresponding addition and removal operations, then re-lock the bottom clamp 66, and then start the ultrasonic generator 4 for cleaning. After cleaning is completed, open the liquid control valve 64 to filter the cleaning solution, and install the appropriate number of filter elements when the next batch of cleaning tasks is carried out.
