Description

Technical Field

[0001] This invention relates to the field of silicon carbide diode technology, and in particular to a silicon carbide diode cleaning device that is easy to handle. Background Technology

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). Currently, diodes generally require cleaning during the manufacturing process, typically using an ultrasonic cleaner. The diodes are placed in the cleaning tank and then removed. To speed up the cleaning process, many diodes are usually placed in the tank together, making the subsequent removal laborious. Furthermore, the diodes usually retain cleaning fluid after removal, requiring an additional drying step, resulting in low efficiency.

[0003] An existing Chinese patent describes a diode cleaning device (CN222402642U). This device allows for the removal of the placement frame and diodes within it by lifting the top cover after cleaning. The frame is then placed on a support rod to allow for drainage of the frame and diodes, which is convenient. However, when the diodes being cleaned have contaminants larger than the mesh size, these contaminants cannot pass through the mesh during cleaning and remain inside. To prevent secondary contamination of subsequent diodes, the frame must be disassembled and cleaned separately, increasing workload and reducing cleaning efficiency. This requires improvement. Summary of the Invention

[0004] To overcome the drawbacks of the problems mentioned in the background, the present invention provides a silicon carbide diode cleaning device that is easy to handle.

It has an inner cover; a barrel-shaped airbag is provided between the outer cover and the inner cover, and the barrel-shaped airbag is limited by the outer cover and the inner cover; the barrel-shaped airbag is divided into a side and a bottom, and the side and bottom of the barrel-shaped airbag are not connected; the outer cover and the inner cover each have several through holes, and the through holes between the outer cover and the inner cover correspond one-to-one; the side of the barrel-shaped airbag has several side holes; the bottom of the barrel-shaped airbag has several bottom holes, and the side holes and bottom holes on the barrel-shaped airbag correspond to the through holes on the outer cover and the inner cover; the hole wall of the bottom hole is set as a deformable structure.

[0006] Furthermore, the side holes are designed as deformable structures.

[0007] Furthermore, the telescopic part of the multi-section push rod is rotatably connected to the ring; each telescopic part of the multi-section push rod is equipped with a drive motor, and the output shafts of all drive motors are fixedly connected to the ring.

[0008] Furthermore, it also includes a slider, a vertical rod, and convex rings; the outer cover and the inner cover are jointly mounted on a slider; the ultrasonic cleaning tank is bolted to a vertical rod, and the vertical rod is slidably connected to the slider; the vertical rod is provided with several convex rings arranged in a vertical array.

[0009] Furthermore, the circular ring and the bearing ring are configured to be rotatably connected; the slider is configured as a nut structure; a lead screw is provided on the upper part of the vertical rod, and the lead screw cooperates with the slider configured as a nut structure.

[0010] Furthermore, it also includes multiple push rods, connecting rings, and elastic air cylinders; all supports are provided with several multiple push rods; the telescopic parts of all multiple push rods are fixed to a connecting ring; an elastic air cylinder is provided on the bearing ring, and the elastic air cylinder cooperates with the connecting ring; the inner side of the elastic air cylinder has several air holes arranged in a ring array, and the air outlet direction of the air holes is inclined downward.

[0011] Furthermore, it also includes a pressing rod, an arc-shaped baffle, a fixing strip, a moving strip, and a spring rod; the bearing ring is set as a hollow structure; each hollow part of the bearing ring has a sliding groove; each sliding groove is slidably connected to an arc-shaped baffle; the bearing ring is fixedly connected to several fixing strips arranged in a ring array; a moving strip is fixedly connected between each pair of adjacent arc-shaped baffles, and the moving strips correspond one-to-one with the fixing strips; several spring rods are provided between each corresponding moving strip and fixing strip; the connecting ring is fixedly connected to several pressing rods arranged in a ring array, and the pressing rods correspond one-to-one with the moving strips.

[0012] Furthermore, it also includes a crossbar and a power motor; all supports are rotatably connected to a crossbar, and multiple push rods are connected to the supports through the crossbar; each support is equipped with a power motor, and the output shafts of all power motors are fixedly connected to the crossbar.

[0013] The beneficial effects of this invention are:

[0014] 1. In this invention, before the next batch of cleaning work, the external air pump is controlled to extract air from the barrel-shaped airbag, causing the barrel-shaped airbag to contract. This expands the bottom and side holes on it, allowing large pieces of dirt remaining in the mesh cylinder that are larger than the original bottom and side holes to be discharged through the expanded bottom and side holes. In this way, by simply and flexibly adjusting the state of the bottom and side holes, the problem of the prior art being solved is that when the diode being cleaned has dirt attached to it that is larger than the mesh frame aperture, the dirt cannot pass through the mesh frame to be discharged during the cleaning process and remains in the mesh frame after cleaning. In order to ensure that the diodes to be cleaned later are not re-contaminated, the mesh frame needs to be cleaned in time, which increases the workload and reduces the cleaning efficiency of the diodes.

[0015] 2. In this invention, during the drying process after the mesh cylinder leaves the cleaning liquid in the ultrasonic cleaning tank, an external air pump is controlled to inject air into the side of the barrel-shaped airbag, causing the side of the barrel-shaped airbag to expand, thereby causing the side hole to contract until it is closed, while the bottom hole of the barrel-shaped airbag remains unchanged. At this time, the external fan dries the diodes in the mesh cylinder from top to bottom, so that the airflow entering the mesh cylinder can be concentrated and pass out through the bottom hole. In this way, the airflow will not pass out through the side hole before it reaches the bottom hole of the mesh cylinder and passes out through the bottom hole, avoiding the phenomenon that the diodes in the lower layer of the mesh cylinder cannot be dried by the airflow due to a large amount of airflow leaking from the side hole. Thus, the drying efficiency of the diodes is guaranteed by flexibly adjusting the state of the side hole.

[0016] 3. This invention periodically controls the telescopic part of the multi-section push rod to drive the ring, drive motor, bearing ring, outer cover, inner cover, and barrel-shaped airbag to move up and down. This causes the outer cover and inner cover to drive the slider to reciprocate up and down on the vertical rod and lead screw. When the slider moves on the vertical rod with several convex rings, the cooperation between the slider and the convex rings causes the mesh cylinder to shake during the up and down movement. This causes the diodes stacked inside the mesh cylinder to shake, which not only shakes out the dirt between adjacent diodes, allowing the dirt to be discharged quickly, but also changes the orientation of the diodes, so that the diodes that were originally attached are no longer attached, avoiding cleaning dead corners, thus significantly improving the cleaning effect.

[0017] 4. In this invention, when the slider moves on the lead screw, the slider, which is configured as a nut structure, causes the outer cover, inner cover, and bearing ring to rotate within the ring under the action of the lead screw. This causes the mesh cylinder formed by the outer cover, inner cover, and barrel-shaped airbag to move up and down in a spiral motion on the lead screw, generating centrifugal force on the diodes inside the mesh cylinder. This causes the diodes to change their position within the mesh cylinder, for example, causing the diodes that were originally located in the center of the mesh cylinder to be centrifugally thrown out to the edge of the mesh cylinder, thus getting closer to the ultrasonic cleaning tank. This ensures that the diodes in each area of ​​the mesh cylinder are uniformly subjected to the ultrasonic cleaning effect, thereby further improving the cleaning effect on the diodes.

[0018] 5. In this invention, when the mesh cylinder moves spirally upward on the lead screw and exceeds the surface of the cleaning liquid in the ultrasonic cleaning tank, the residual cleaning liquid on the diode surface can be centrifugally spun out by centrifugal drying. In this way, the diode in the mesh cylinder achieves a certain degree of drying effect before being dried by the external fan, reducing the time required for subsequent drying and thus improving work efficiency.

Detailed Implementation

[0028] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0029] Example 1

[0030] A silicon carbide diode cleaning device that is easy to handle, such as Figures 1-8 As shown, the device includes an ultrasonic cleaning tank 1, a mounting frame 2, a bracket 3, a multi-section push rod 4, a circular ring 5, a drive motor 6, a load-bearing ring 7, and an outer cover 8. The ultrasonic cleaning tank 1 is bolted to the mounting frame 2. The mounting frame 2 is bolted to at least two symmetrically distributed brackets 3. Each bracket 3 is equipped with a multi-section push rod 4. The telescopic parts of all multi-section push rods 4 are provided with a circular ring 5. The circular ring 5 is provided with a load-bearing ring 7. The load-bearing ring 7 is detachably connected to the outer cover 8.

[0031] It also includes an inner cover 9 and a barrel-shaped airbag 10; the inner cover 9 is detachably connected to the support ring 7; a barrel-shaped airbag 10 is provided between the outer cover 8 and the inner cover 9, and the barrel-shaped airbag 10 is limited by the outer cover 8 and the inner cover 9; the barrel-shaped airbag 10 is divided into a side and a bottom, and the side and bottom of the barrel-shaped airbag 10 are not connected; the outer cover 8 and the inner cover 9 each have several through holes, and the through holes between the outer cover 8 and the inner cover 9 correspond one-to-one; the side of the barrel-shaped airbag 10 is provided with several side holes 10002; the bottom of the barrel-shaped airbag 10 is provided with several bottom holes 10001, and the side holes 10002 and bottom holes 10001 on the barrel-shaped airbag 10 correspond to the through holes on the outer cover 8 and the inner cover 9; the hole wall of the bottom hole 10001 is set as a deformable structure.

[0032] The side hole 10002 is designed as a deformable structure.

[0033] The telescopic part of the multi-section push rod 4 is rotatably connected to the ring 5; each telescopic part of the multi-section push rod 4 is equipped with a drive motor 6, and the output shafts of all drive motors 6 are fixedly connected to the ring 5.

[0034] The specific workings of this invention are as follows:

[0035] It should be noted that the apertures of the through holes on the outer cover 8 and inner cover 9 are much larger than the size of the diode, so that the apertures of the bottom hole 10001 and the side hole 10002 can be flexibly adjusted. Before cleaning the diode, the external air pump is controlled to inject or extract air into the barrel-shaped air bag 10 according to the size of the diode to be cleaned, so that the bottom hole 10001 and the side hole 10002 can expand or contract adaptively according to the size of the diode to be cleaned. This avoids the diode from leaking out during the cleaning process because the apertures of the bottom hole 10001 and the side hole 10002 are larger than the diode, or the cleaning fluid from not being able to flow normally because the apertures of the bottom hole 10001 and the side hole 10002 are too small.

[0036] Specifically, in use, the present invention first injects cleaning fluid for cleaning diodes into the ultrasonic cleaning tank 1. Then, the diodes to be cleaned are placed inside the mesh cylinder formed by the outer cover 8, inner cover 9, and barrel-shaped airbag 10. Subsequently, the telescopic part of the multi-section push rod 4 is controlled to drive the ring 5, drive motor 6, bearing ring 7, outer cover 8, inner cover 9, and barrel-shaped airbag 10 to move downwards synchronously, so that the mesh cylinder formed by the outer cover 8, inner cover 9, and barrel-shaped airbag 10 is submerged in the cleaning fluid of the ultrasonic cleaning tank 1, and the liquid level of the cleaning fluid is slightly higher than the upper part of the barrel-shaped airbag 10. Then, the ultrasonic cleaning tank 1 is controlled to perform ultrasonic cleaning on the diodes inside the mesh cylinder.

[0037] After the cleaning process is completed, the telescopic part of the multi-section push rod 4 is controlled to drive the ring 5, drive motor 6, bearing ring 7, outer cover 8, inner cover 9, and barrel-shaped airbag 10 to move upward synchronously. This causes the mesh cylinder formed by the outer cover 8, inner cover 9, and barrel-shaped airbag 10 to leave the cleaning liquid in the ultrasonic cleaning tank 1. An external fan is then used to air-dry the diodes inside the mesh cylinder from top to bottom, thereby improving the drainage efficiency and allowing the diodes to be quickly put into the next production process. During the air-drying process after the mesh cylinder leaves the cleaning liquid in the ultrasonic cleaning tank 1, an external air pump is controlled to inject air into the side of the barrel-shaped airbag 10, causing the side of the barrel-shaped airbag 10 to expand, thereby... This causes the side hole 10002 to contract until it is closed, while the bottom hole 10001 of the barrel-shaped airbag 10 remains unchanged. At this time, the external fan dries the diodes inside the mesh cylinder from top to bottom, so that the airflow entering the mesh cylinder can be concentrated and pass out through the bottom hole 10001. In this way, the airflow will not pass out through the side hole 10002 before it reaches the bottom hole 10001 of the mesh cylinder and passes out through the bottom hole 10001 of the mesh cylinder. This avoids the phenomenon that a large amount of airflow will leak from the side hole 10002, causing the diodes in the lower layer of the mesh cylinder to not be dried by the airflow. In this way, the drying efficiency of the diodes is guaranteed by flexibly adjusting the state of the side hole 10002.

[0038] After the cleaning work is completed and the bottom of the mesh cylinder extends beyond the ultrasonic cleaning tank 1, the output shaft of the control drive motor 6 drives the ring 5, the bearing ring 7, the outer cover 8, the inner cover 9 and the barrel-shaped air bag 10 to rotate, so that the mesh cylinder rotates from a vertical state to a horizontal state, so that the opening of the mesh cylinder faces forward, so as to facilitate the removal of the diode.

[0039] Before proceeding with the next batch of cleaning, the external air pump extracts air from the barrel-shaped airbag 10, causing it to contract. This expands the bottom hole 10001 and side hole 10002, allowing large pieces of dirt remaining in the mesh cylinder—larger than the original diameter of the bottom hole 10001 and side hole 10002—to be discharged through the expanded holes. This simple and flexible adjustment of the bottom hole 10001 and side hole 10002 solves the problem in existing technologies where, when the diodes being cleaned have dirt larger than the mesh frame's aperture, the dirt cannot pass through the mesh frame during cleaning and remains inside after cleaning. To ensure that subsequent diodes are not re-contaminated, the mesh frame needs to be cleaned promptly, increasing workload and reducing diode cleaning efficiency.

[0040] Example 2

[0041] Based on the above embodiment 1, as follows Figures 2-8As shown, it also includes a slider 40, a vertical rod 41, and a convex ring 43; the outer cover 8 and the inner cover 9 are jointly installed with a slider 40; the ultrasonic cleaning tank 1 is bolted to the vertical rod 41, and the vertical rod 41 is slidably connected to the slider 40; the vertical rod 41 is provided with a number of convex rings 43 arranged in a vertical array.

[0042] The ring 5 and the bearing ring 7 are rotatably connected; the slider 40 is a nut structure; the upper part of the vertical rod 41 is provided with a lead screw 42, and the lead screw 42 cooperates with the slider 40 which is a nut structure.

[0043] It also includes a multi-section push rod 20, a connecting ring 21, and an elastic air cylinder 30; all brackets 3 are provided with at least two multi-section push rods 20; the telescopic parts of all multi-section push rods 20 are fixedly connected to a connecting ring 21; the bearing ring 7 is provided with an elastic air cylinder 30, and the elastic air cylinder 30 cooperates with the connecting ring 21; the inner side of the elastic air cylinder 30 is provided with a number of air holes arranged in a ring array, and the air outlet direction of the air holes is inclined downward.

[0044] The specific workings of this invention are as follows:

[0045] During the cleaning process described above, the telescopic part of the multi-section push rod 4 is periodically controlled to drive the ring 5, drive motor 6, bearing ring 7, outer cover 8, inner cover 9, and barrel-shaped airbag 10 to move up and down. This causes the outer cover 8 and inner cover 9 to drive the slider 40 to reciprocate up and down on the vertical rod 41 and lead screw 42. When the slider 40 moves on the vertical rod 41 which is provided with several convex rings 43, the cooperation between the slider 40 and the convex rings 43 causes the mesh cylinder to shake during the up and down movement. This causes the diodes piled inside the mesh cylinder to shake, which not only shakes out the dirt between the adjacent diodes and allows the dirt to be discharged quickly, but also changes the orientation of the diodes, so that the diodes that were originally attached are no longer attached, avoiding cleaning dead corners, thus significantly improving the cleaning effect.

[0046] When the slider 40 moves on the lead screw 42, the slider 40, which is configured as a nut structure, causes the outer cover 8, inner cover 9, and bearing ring 7 to rotate within the ring 5 under the action of the lead screw 42. This causes the mesh cylinder formed by the outer cover 8, inner cover 9, and barrel-shaped airbag 10 to move up and down in a spiral motion on the lead screw 42. This causes the diodes inside the mesh cylinder to generate centrifugal force, thereby changing the position of the diodes inside the mesh cylinder. For example, the diodes that were originally in the center area of ​​the mesh cylinder are centrifugally thrown out to the edge area of ​​the mesh cylinder, thus getting closer to the ultrasonic cleaning tank 1. This allows the diodes in each area of ​​the mesh cylinder to be uniformly subjected to the ultrasonic cleaning effect, thereby further improving the cleaning effect on the diodes.

[0047] Furthermore, when the mesh cylinder moves spirally upward on the lead screw 42 and exceeds the surface of the cleaning liquid in the ultrasonic cleaning tank 1, the residual cleaning liquid on the diode surface can be centrifugally ejected by centrifugal spin-drying. In this way, the diode inside the mesh cylinder achieves a certain degree of drying effect before being dried by the external fan, reducing the time required for subsequent drying and thus improving work efficiency.

[0048] When the mesh cylinder moves spirally upward on the lead screw 42, it drives the elastic air cylinder 30 to move upward. At this time, the telescopic part of the multi-section push rod 20 is synchronously controlled to drive the connecting ring 21 to move downward, so that the connecting ring 21 and the elastic air cylinder 30 move towards each other. As the connecting ring 21 and the elastic air cylinder 30 continue to move towards each other, the elastic air cylinder 30 will be pressed by the connecting ring 21, so that the air in the elastic air cylinder 30 is sprayed out through the air hole on the elastic air cylinder 30 towards the diode in the mesh cylinder. In this way, while the residual cleaning liquid on the surface of the diode is centrifugally thrown out, the airflow sprayed through the air hole on the elastic air cylinder 30 pre-dries the diode in the mesh cylinder, so as to reduce the time required for subsequent drying and improve work efficiency. When the connecting ring 21 no longer presses the elastic air cylinder 30, the elastic air cylinder 30 returns to its initial state under its own elastic restoring force.

[0049] Example 3

[0050] Based on the above embodiment 2, as Figures 2-8 As shown, it also includes a pressing rod 22, an arc-shaped baffle 23, a fixing strip 24, a moving strip 25, and a spring rod 26; the bearing ring 7 is configured with a hollow structure; each hollow part of the bearing ring 7 has a sliding groove 7001; each sliding groove 7001 is slidably connected to an arc-shaped baffle 23; the bearing ring 7 is fixedly connected to at least four fixing strips 24 arranged in a ring array; a moving strip 25 is fixedly connected between each pair of adjacent arc-shaped baffles 23, and the moving strips 25 correspond one-to-one with the fixing strips 24; several spring rods 26 are provided between each corresponding moving strip 25 and fixing strip 24; the connecting ring 21 is fixedly connected to at least four pressing rods 22 arranged in a ring array, and the pressing rods 22 correspond one-to-one with the moving strips 25.

[0051] It also includes a crossbar 27 and a power motor 28; all brackets 3 are rotatably connected to a crossbar 27, and the multi-section push rod 20 is connected to the bracket 3 through the crossbar 27; each bracket 3 is equipped with a power motor 28, and the output shaft of all power motors 28 is fixedly connected to the crossbar 27. The output shaft of the power motor 28 drives the crossbar 27 and the multi-section push rod 20 to rotate, so that the multi-section push rod 20, the connecting ring 21 and the pressing rod 22 rotate from the vertical state to the horizontal state, so as to avoid the presence of the pressing rod 22 affecting the rise and rotation of the outer cover 8, the inner cover 9, the barrel-shaped airbag 10 and the elastic air cylinder 30, and ensure that these components can rise and rotate smoothly.

[0052] The specific workings of this invention are as follows:

[0053] During the cleaning process, the dirt that was originally attached to the diode surface will float on the surface of the cleaning solution after being detached from the diode. If this floating dirt cannot be discharged in time, it may re-adhere to the diode surface or inside the mesh when the mesh cylinder moves the diode upwards away from the water surface, causing secondary pollution.

[0054] Therefore, when the telescopic part of the multi-section push rod 4 drives the ring 5, drive motor 6, bearing ring 7, outer cover 8, inner cover 9, and barrel-shaped airbag 10 to move upward, the telescopic part of the multi-section push rod 20 controls the connecting ring 21 and pressing rod 22 to move downward, causing the pressing rod 22 to move towards the bearing ring 7, and then the pressing rod 22 to move towards the moving strip 25 on the bearing ring 7. As the pressing rod 22 and the moving strip 25 continue to move towards each other, the pressing rod 22 will push the moving strip 25 towards the fixed strip 2. 4. Pressing down, the moving bar 25 will drive the arc-shaped baffle 23 to move downward in the slide groove 7001 after being subjected to pressure, thereby opening the hollow part of the bearing ring 7. When the screen cylinder moves upward in the cleaning liquid, the screen cylinder will temporarily push the water flow inside the screen cylinder upward, causing the liquid level inside the screen cylinder to be higher than the liquid level outside the screen cylinder. At this time, the hollow part of the bearing ring 7 opens, and the liquid level inside the screen cylinder will flow from high to low to the outside of the screen cylinder, so that the dirt floating on the liquid surface inside the screen cylinder can flow out of the screen cylinder along with the liquid flow. Subsequently, as the mesh cylinder moves downward, the pressing rod 22 moves away from the moving bar 25, causing the moving bar 25 to move upward under the elastic restoring force of the spring rod 26, thus re-sealing the hollowed-out area of ​​the bearing ring 7; or, this operation can be achieved by actively controlling the telescopic part of the multi-section push rod 20 to move the connecting ring 21 and the pressing rod 22 upward away from the moving bar 25, thereby preventing the dirt floating on the liquid surface outside the mesh cylinder from flowing back into the mesh cylinder. In this way, the problem mentioned above is solved, where dirt originally attached to the diode surface floats on the surface of the cleaning liquid after detaching from the diode, and if the dirt floating on the liquid surface cannot be discharged in time, when the mesh cylinder moves the diode upward away from the water surface, the dirt will re-attach to the diode surface or to the inside of the mesh cylinder, causing secondary pollution.

[0055] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
