Description

Technical Field

[0001] This utility model application relates to the field of planar rectifier die technology, specifically a vacuum adsorption surface cleaning device for planar rectifier dies. Background Technology

[0002] Planar rectifier dies are key electronic components used to convert alternating current (AC) to direct current (DC). Their core structure is made of semiconductor materials and is typically manufactured using planar processes, resulting in high precision and stability. The die contains a PN junction, which achieves rectification through unidirectional conductivity. When AC is applied to the die, the PN junction only allows current to flow in one direction, thus converting the AC signal into a pulsating DC signal. Planar rectifier dies feature low forward voltage drop, high reverse withstand voltage, and high efficiency, and are widely used in power adapters, chargers, and industrial equipment. Their planar structure design not only improves heat dissipation but also enhances reliability and lifespan, making them an indispensable component in modern electronic devices.

[0003] Traditional cleaning methods mainly include manual wiping, ultrasonic cleaning, and airflow purging. Manual wiping is inefficient and can easily cause surface scratches due to improper operation. Although ultrasonic cleaning can remove some contaminants, it may damage the internal structure of the core due to high-frequency vibration. Airflow purging is difficult to completely remove tiny particles and deposits. In addition, traditional methods are difficult to automate, the cleaning effect is unstable, and they cannot meet the needs of large-scale production. Summary of the Invention

[0004] To address the inconveniences, lack of automation, unstable cleaning results, and inability to meet the demands of large-scale production associated with traditional methods, this invention provides a vacuum adsorption surface cleaning device for planar rectifier cores to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vacuum adsorption surface cleaning device for a planar rectifier core includes a conveyor housing. A first roller is rotatably mounted at one end inside the conveyor housing, and a second roller is symmetrically rotatably mounted at the other end. A conveyor belt is fitted onto the first and second rollers. A fixing frame is fixed inside the conveyor housing. A first servo motor is fixed to one side of the conveyor housing, and its output end is fixedly connected to the first roller. A negative pressure device is provided on one side of the conveyor housing, and several negative pressure holes are formed on the conveyor belt. A second servo motor is fixed to the side of the conveyor housing near the first servo motor, and a first helical gear is fixed to its output end. A fixing block is symmetrically fixed to the bottom of the conveyor housing, and a cleaning roller is rotatably mounted inside the fixing block. A second helical gear is fixed to the end of the cleaning roller near the first helical gear, and the second helical gear meshes with the first helical gear.

[0007] Furthermore, the negative pressure device includes a fan, the air intake of which is connected to the interior of the fixed frame.

[0008] Furthermore, the conveyor belt is attached to the fixed frame, and the material of the conveyor belt is hard leather.

[0009] Furthermore, a support column is fixed to the side of the conveyor housing near the first servo motor, and a recycling box is provided between the support column and the fan, with a partition plate fixed inside the recycling box.

[0010] Furthermore, the partition plate is located directly below the first servo motor, and the width of the recycling bin is the same as the width of the conveyor belt.

[0011] Furthermore, one end of the fixing frame is rotatably connected to the second roller, and the other end of the fixing frame is located on one side of the first roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by placing the planar rectifier die on a conveyor belt and simultaneously starting a fan, the fan draws away the air inside the mounting frame, creating a negative pressure inside the mounting frame. The conveyor belt has negative pressure holes connected to the mounting frame, allowing the planar rectifier die to adhere to the conveyor belt. A first servo motor then drives the conveyor belt to move, causing the planar rectifier die to pass through a cleaning roller, which cleans the die. This solves the problems of traditional methods, such as numerous inconveniences, difficulty in automation, unstable cleaning results, and inability to meet the needs of large-scale production.

[0014] 2. In this utility model, a recycling bin is set below the outer shell of the re-conveyor, and a partition is set inside the recycling bin for separation. One end of the recycling bin collects the dust after the planar rectifier core is cleaned by the cleaning roller, and the other end is used to collect the dust when the planar rectifier core moves to the end near the first roller by the conveyor belt. At this time, the conveyor belt is away from the negative pressure environment inside the fixed frame, and then the planar rectifier core falls into the recycling bin under the action of gravity.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A vacuum adsorption surface cleaning device for a planar rectifier core includes a conveyor housing 1. A first roller 2 is rotatably mounted at one end inside the conveyor housing 1, and a second roller 3 is symmetrically rotatably mounted at the other end inside the conveyor housing 1. A conveyor belt 4 is fitted onto the first roller 2 and the second roller 3. A fixing frame 6 is fixed inside the conveyor housing 1. A first servo motor 5 is fixed on one side of the conveyor housing 1, and the output end of the first servo motor 5 is fixedly connected to the first roller 2. A negative pressure device is provided on one side of the conveyor housing 1, and several negative pressure holes are opened on the conveyor belt 4. A second servo motor 10 is fixed on the side of the conveyor housing 1 near the first servo motor 5, and a first helical gear 11 is fixed on the output end of the second servo motor 10. Fixing blocks 8 are symmetrically fixed at the bottom of the conveyor housing 1. A cleaning roller 9 is rotatably mounted inside the fixing block 8. A second helical gear 12 is fixed on the end of the cleaning roller 9 near the first helical gear 11. The second helical gear 12 meshes with the first helical gear 11, so that the cleaning roller 9 cleans the planar rectifier core.

[0023] Specifically, the negative pressure device includes a fan 7, the air intake of the fan 7 is connected to the inside of the fixed frame 6, the conveyor belt 4 is attached to the fixed frame 6, the conveyor belt 4 is made of hard leather, one end of the fixed frame 6 is rotatably connected to the second roller 3, and the other end of the fixed frame 6 is located on one side of the first roller 2, so as to facilitate the conveyor belt 4 to transport the planar rectifier core.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support column 13 is fixed on the side of the conveyor housing 1 near the first servo motor 5. A recycling box 14 is provided between the support column 13 and the fan 7. A partition plate 15 is fixed inside the recycling box 14 so that the recycling box 14 can collect the dust after cleaning by the cleaning roller 9.

[0025] Specifically, the partition plate 15 is located directly below the first servo motor 5, and the width of the recycling bin 14 is the same as the width of the conveyor belt 4, so that the planar rectifier die falls into the other end of the recycling bin 14.

[0026] Working principle: The operator places the planar rectifier core on the conveyor belt 4. At this time, the fan 7 is started, which draws out the air inside the fixing frame 6, creating a negative pressure inside the fixing frame 6. The fixing frame 6 firmly adheres the planar rectifier core to the conveyor belt 4 through the negative pressure hole. The first servo motor 5 is then started, which drives the first roller 2 to rotate, thereby moving the conveyor belt 4. At the same time, the second servo motor 10 is started, which drives the first helical gear 11 to rotate. The first helical gear 11 meshes with the second helical gear 12, thereby driving the cleaning roller 9 to rotate. When the conveyor belt 4 carries the planar rectifier core past the cleaning roller 9, the cleaning roller 9 cleans the planar rectifier core. When the conveyor belt 4 carries the planar rectifier core below the first servo motor 5, the connection between the negative pressure hole on the conveyor belt 4 and the fixing frame 6 is interrupted, and the planar rectifier core on the conveyor belt 4 falls into the recycling box 14 under the action of gravity.
