[0049] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] Please see Figures 1-3 This application provides the following technical solutions:

[0051] A chip tray cleaning mechanism is disclosed. For ease of explanation, the forward direction of the tray 100 during transport is considered as "forward," meaning the tray moves forward after entering the cleaning mechanism. This cleaning mechanism includes a tray transport unit 1, which horizontally transports the tray 100 to be cleaned, causing the tray 100 to move forward. A first tray cleaning unit 2 and a second tray cleaning unit 3 are respectively arranged across the transport path of the tray transport unit 1. The second tray cleaning unit 3 is located in front of the first tray cleaning unit 2. The first tray cleaning unit 2 includes a dry ultrasonic cleaning assembly for dry ultrasonic cleaning of the tray 100. The second tray cleaning unit 3 includes an air knife assembly 32 for air-blowing cleaning of the tray 100.

[0052] This solution employs a combination of dry ultrasonic cleaning and air blowing to clean the tray 100. Dry ultrasonic cleaning allows for the direct placement of chips after cleaning, unlike conventional water cleaning methods which require waiting for complete drying. Following the dry ultrasonic cleaning, an air knife is then used for further air blowing to remove dust and other contaminants from the tray 100.

[0053] Based on the above implementation plan, see Figure 5 The pallet conveying unit 1 includes two parallel outer frames, with two pallet conveying rollers 11 positioned between them. One of the two conveying rollers 11 is rotatably mounted at each end of the conveying path, and one of the pallet conveying rollers 11 is linked to a motor, which serves as the power source. Two pallet conveying belts 12 are wound around the rollers of the two pallet conveying rollers 11, with a gap between them. Furthermore, a pallet conveying frame 13 is positioned inside the annular conveying path formed by the pallet conveying belts 12, and the upper surface of the pallet conveying frame 13 is flat.

[0054] The pallet conveyor belt 12 has two parallel sections at the top and bottom, and arc-shaped sections at both ends. The upper surface of the pallet conveyor frame 13 is located below the upper parallel section of the pallet conveyor belt 12. The pallet conveyor belt 12 serves as the main power structure for conveying the pallet 100, and the pallet 100 is placed on the pallet conveyor belt 12. The pallet conveyor frame 13 serves as an auxiliary support structure for the pallet, applying an auxiliary lifting force to the pallet 100.

[0055] Based on the above implementation plan, see Figure 2The first pallet cleaning unit 2 includes a pallet cleaning frame 21, which spans above the pallet conveyor belt 12. Its two sides are fixedly connected to an external support structure, forming a portal frame structure spanning the pallet conveyor unit 1. The pallet cleaning frame 21 includes a first fixed frame 211 and a first movable frame 212. The first movable frame 212 can move vertically, approaching or moving away from the pallet conveyor belt 12. The first movable frame 212 only needs to be able to rise and fall; it can be adapted using existing technology, and its specific structural form will not be elaborated here. A first pallet cleaning assembly 22 is mounted on the first movable frame 212. The first pallet cleaning assembly 22 is a dry ultrasonic cleaning assembly. The specific structural form of the dry ultrasonic cleaning assembly can be achieved using existing technology.

[0056] Based on the above implementation plan, see Figure 1 and Figure 2 The second pallet cleaning unit 3 includes a cleaning cover 31, which is a rectangular cover with an open bottom. The cleaning cover 31 covers the conveying path of the pallet conveying unit 1, and the coverage area of ​​the cleaning cover 31 is the cleaning area of ​​the second pallet cleaning unit 3. The projected area of ​​the cleaning cover 31 on the conveying path of the pallet conveying unit 1 is larger than the area of ​​the pallet 100. An exhaust pipe is provided on the top of the cleaning cover 31, and the exhaust pipe is connected to the internal space of the cleaning cover 31. The air knife assembly 32 is located inside the cleaning cover 31.

[0057] With this structural design, a relatively enclosed space is formed by the cleaning hood 31. Under the impact of the airflow from the air knife assembly 32, the airflow carries impurities blown away from the tray 100 and is blown out from the exhaust pipe at the top of the cleaning hood 31. As a further optimization of the design, an exhaust duct can also be connected to the outside of the exhaust duct.

[0058] Based on the above implementation plan, see Figure 6 The air knife assembly 32 includes an air knife bracket 321, whose bottom sides are fixedly connected to the outer frame of the pallet conveying unit 1, forming a structure in which the air knife bracket 321 spans above the pallet conveying unit 1. An air knife housing 322 is rotatably connected to the air knife bracket 321. A bolt locking structure is provided between the air knife housing 322 and the air knife bracket 321, which can lock the angle of the air knife housing 322 by tightening the bolts. An air outlet is provided on the side of the air knife housing 322 facing the pallet conveying unit 1. An air duct connector 323 is provided on the air knife housing 322, and the air duct connector 323 is connected to the air source assembly via a pipe. The air source assembly only needs to supply air to the inside of the air knife housing 322, such as an air pump.

[0059] Four air duct connectors 323 are provided in total, forming a uniformly distributed structure. The air knife housing 322 has four chambers inside, and each chamber is provided with one air duct connector 323. The air outlet of the air knife housing 322 is a long strip slit. One side of each chamber of the air knife housing 322 is connected to the air outlet, and the chambers of the air knife housing 322 are connected to each other.

[0060] The air knife assembly 32 of this structure forms an airflow that blows onto the tray. Considering that there may be residual impurities on the tray 100 after the first tray cleaning unit 2 uses dry ultrasonic cleaning, the air knife assembly 32 is used for further cleaning.

[0061] Based on the above implementation plan, see Figure 7 To ensure that the tray 100 is stable during air blowing cleaning, the second tray cleaning unit 3 also includes a second pressure plate assembly 33, which is also located inside the cleaning cover 31 and is located on the side of the air knife assembly 32 facing the first tray cleaning unit 2; the second pressure plate assembly 33 can apply downward pressure to the tray 100.

[0062] The second pressure plate assembly 33 includes a second pressure plate fixing frame 331 and a second pressure plate movable frame 332. The second pressure plate fixing frame 331 also adopts a spanning structure, positioning itself on the pallet conveying unit 1 to form a portal frame structure. The second pressure plate movable frame 332 is slidably connected to the second pressure plate fixing frame 331; the second pressure plate movable frame 332 can move towards or away from the pallet conveying unit 1. A second pressure plate roller 333 is rotatably connected to the lower part of the second pressure plate movable frame 332.

[0063] A cylinder is provided between the second pressure plate fixing frame 331 and the second pressure plate movable frame 332. The outer side of the cylinder body is fixedly connected to the second pressure plate fixing frame 331, and the piston end of the cylinder body is fixedly connected to the second pressure plate movable frame 332.

[0064] By setting a second pressure roller 333, the second pressure roller 333 applies downward pressure to the pallet 100 below it. This downward pressure needs to be sufficient to ensure that the pallet 100 can still move with the pallet conveyor belt 12.

[0065] Based on the above implementation plan, see Figure 7A horizontal plate is installed at the lower part of the second pressure plate movable frame 332, and a roller frame is installed corresponding to the second pressure plate roller 333. The second pressure plate roller 333 and the roller frame are rotatably connected. Two vertical connecting rods are installed on the upper part of the roller frame, and the connecting rods pass through the horizontal plate. Limiting nuts are installed on the rods located on the upper part of the horizontal plate. The limiting nuts prevent the connecting rods from sliding downwards excessively, causing the roller frame to detach from the horizontal plate. A counterweight is installed on the roller frame, and the weight of the roller frame and the second pressure plate roller 333 forms a downward pressure on the pallet 100. By simply adjusting the corresponding counterweight, the pallet 100 can be pressed down to prevent it from being blown away by the airflow, while also allowing the pallet 100 to be transported normally.

[0066] Based on the above implementation scheme, since this scheme mainly cleans the dust on the pallet 100, in order to prevent dust from accumulating on the second conveyor belt 12, this scheme also includes an antistatic component 4. The antistatic component 4 is located at the end of the pallet conveying unit 1 and can eliminate static electricity on the outer surface of the pallet conveyor belt 12. See Figure 5 The antistatic assembly 4 includes an antistatic frame 41, which is positioned above the front end of the pallet conveyor belt 12. The antistatic frame 41 is telescopic, allowing it to move closer to or away from the pallet conveyor belt 12. An antistatic roller 42 is rotatably connected to the lower part of the antistatic frame 41, which eliminates static electricity on the outer surface of the pallet conveyor belt 12. The antistatic frame 41 can be a manually adjustable telescopic frame, and the antistatic roller 42 can be any existing roller structure with antistatic function, as long as it can eliminate static electricity on the outer surface of the pallet conveyor belt 12. By eliminating static electricity, dust is prevented from adhering to the pallet conveyor belt 12, and thus, as the pallet 100 is cleaned, the conveyor belt itself is also cleaned during use.
