Compressed air is ejected from the air nozzle 14 through the air inlet pipe 15 and the disc 13. The air nozzle 14 sprays air evenly onto the surface of the injection molded part, blowing off impurities or foreign objects adhering to the surface of the injection molded part. The vacuum pump operates through the air extraction pipe 16 and the horn 1. 7. The impurities or foreign objects blown off by the air nozzle 14 are sucked away. This step, through the arrangement of the first servo motor 11, air distributor 12, turntable 13, air nozzle 14, air inlet pipe 15, air extraction pipe 16 and horn 17, forms a surface cleaning structure for injection molded parts. This realizes the function of blowing off the impurities or foreign objects adhering to the surface of injection molded parts, solving the problem of impurities or foreign objects being distributed in the air after being blown off and causing pollution, reducing the situation of impurities or foreign objects flying to the outside of the cleaning box 1, and improving the uniformity of surface cleaning of injection molded parts.

[0025] like Figure 2 and Figure 3As shown, the clamping assembly includes a second servo motor 2, a rotating shaft 21, a clamping frame 22, a push rod 23, and a spring 24. The second servo motor 2 is fixedly connected to the top of the cleaning box 1. The rotating shaft 21 is fixedly connected to the transmission end of the second servo motor 2. The clamping frame 22 is fixedly connected to the bottom end of the rotating shaft 21. The push rod 23 is slidably connected to the middle of the clamping frame 22. Multiple sets of push rods 23 are arranged symmetrically in the middle of the clamping frame 22. The spring 24 is sleeved on the outer side wall of the push rods 23 that are far apart from each other. Anti-slip components are provided at the ends of the push rods 23 that are close to each other. During operation, the injection molded part is placed in the middle of the clamping frame 22, and the push rod 23 is pulled outward, stretching the spring 24. The injection molded part is placed between the multiple sets of push rods 23. The push rod 23 is released, and the spring 24 is stretched. The moving push rod 23 moves closer to the injection molded part, clamping and fixing the injection molded part in the middle of the clamping frame 22. The anti-slip component increases the friction between the push rod 23 and the injection molded part. The second servo motor 2 is started, and the second servo motor 2 drives the rotating shaft 21 and the clamping frame 22 to rotate. The clamping frame 22 drives the injection molded part to rotate evenly, so that the air nozzle 14 blows air evenly on the surface of the injection molded part. This step, through the setting of the flexible strip 3, the support rod 31 and the fixing block 32, forms the injection molded part fixing clamping structure, realizing the function of clamping and fixing the injection molded part inside the cleaning box 1. It solves the problem of the injection molded part becoming loose when cleaning impurities inside the cleaning box 1, improves the stability of the injection molded part when fixed inside the cleaning box 1, and improves the uniformity of the rotation of the injection molded part during cleaning impurities.

The ends of the flexible strip 3 are respectively fixedly connected to the ends of a pair of top rods 23. The support rod 31 is rotatably connected to the side wall of the flexible strip 3 near the clamping frame 22. The support rod 31 and the fixing block 32 are engaged. During operation, after the injection molded part is cleaned of impurities in the middle of the clamping frame 22, the flexible strip 3 is pulled, and the flexible strip 3 drives the top rod 23 away from the clamping frame 22. The support rod 31 is rotated and inserted into the middle of the fixing block 32, thereby fixing the top rod 23. This step, through the arrangement of the flexible strip 3, the support rod 31, and the fixing block 32, forms a clamp fixing structure, which realizes the function of limiting and fixing the top rod 23, making it convenient for the injection molded part to be removed from the middle of the clamping frame 22 or clamped, and improving the convenience of clamping the injection molded part.

[0027] like Figure 2 and Figure 4As shown, the cleaning assembly includes a fixed plate 4 and a scraper 41. The fixed plate 4 is fixedly connected to the outer wall of the turntable 13. A pair of fixed plates 4 are provided on the outer wall of the turntable 13 and are arranged symmetrically.

During operation, when the turntable 13 rotates, it drives the fixed plate 4 and the scraper 41 to rotate on the inner wall of the cleaning box 1. The scraper 41 contacts the inner wall of the cleaning box 1 and scrapes off the dust or impurities adhering to the inner wall of the cleaning box 1. This step, through the arrangement of the fixed plate 4 and the scraper 41, forms the cleaning structure for the inner wall of the cleaning box 1, realizing the function of scraping dust from the inner wall of the cleaning box 1. This solves the problem of dust or foreign objects adhering to the inner wall of the cleaning box 1, causing dirt on the inner wall of the cleaning box 1, and improves the cleanliness of the inner wall of the cleaning box 1.

[0028] like Figure 3 As shown, the anti-slip component includes an anti-slip pad 5; the anti-slip pad 5 is fixedly connected to the close ends of the ejector rod 23; during operation, when the ejector rod 23 clamps the injection molded part, the anti-slip pad 5 contacts the injection molded part, increasing the friction between the ejector rod 23 and the injection molded part; this step, through the setting of the anti-slip pad 5, forms an anti-slip structure at the end of the ejector rod 23, increases the friction between the ejector rod 23 and the injection molded part, and reduces the slippage that occurs when the injection molded part is clamped.

[0029] like Figure 2 and Figure 4 As shown, the collection component includes a dust collection box 6; the dust collection box 6 is detachably installed at the bottom of the cleaning box 1; during operation, clean water is injected into the dust collection box 6, and the dust or impurities inside the cleaning box 1 fall into the dust collection box 6 and are collected by the dust collection box 6; this step, through the setting of the dust collection box 6, forms a dust or impurity collection structure, improves the convenience of collecting impurities or foreign objects, and reduces the situation of dust or foreign objects flying inside the cleaning box 1.

[0030] During operation, the injection molded part to be pre-cleaned is placed on the clamping assembly inside the cleaning chamber 1. The clamping assembly secures the injection molded part inside the cleaning chamber 1. The impurity removal assembly is activated, blowing air onto the injection molded part to remove impurities or foreign objects adhering to its surface. After cleaning, the injection molded part is removed from the clamping assembly, and then the fixing assembly is used to fix the clamping assembly in a pre-clamped state. Some of the cleaned impurities or foreign objects are collected by the collection assembly. The injection molded part is placed inside the cleaning chamber 1 via the clamping assembly, and compressed air is connected to the air inlet pipe 15. An external vacuum pump is connected to the extraction pipe 16. The first servo motor 11 is started, which drives the air nozzle 14 to rotate. Compressed air is ejected from the air nozzle 14 through the air inlet pipe 15 and the turntable 13. The air nozzle 14 sprays air evenly onto the surface of the injection molded part, blowing off impurities or foreign objects adhering to the surface of the injection molded part. The vacuum pump sucks away the impurities or foreign objects blown off by the air nozzle 14 through the extraction pipe 16 and the horn 17. The injection molded part is placed in the middle of the clamping frame 22. The ejector rod 23 is pulled outward, and the spring 24 is stretched. The injection molded part is placed between multiple sets of ejector rods 23. Release the ejector rod 23. The spring 24 drives the ejector rod 23 closer to the injection molded part, clamping and fixing the injection molded part in the middle of the clamping frame 22. The anti-slip component increases the friction between the ejector rod 23 and the injection molded part. Start the second servo motor 2. The second servo motor 2 drives the rotating shaft 21 and the clamping frame 22 to rotate. The clamping frame 22 drives the injection molded part to rotate evenly, so that the air nozzle 14 blows air evenly on the surface of the injection molded part. After the injection molded part is cleaned of impurities in the middle of the clamping frame 22, pull the flexible strip 3. The flexible strip 3 drives the ejector rod 23 away from the clamping frame 22, rotating the support rod 31. Insert the support rod 31 into the middle of the fixing block 32 to fix the top rod 23; when the turntable 13 rotates, it drives the fixing plate 4 and the scraper 41 to rotate on the inner wall of the cleaning box 1. The scraper 41 contacts the inner wall of the cleaning box 1 and scrapes off the dust or impurities adhering to the inner wall of the cleaning box 1; when the top rod 23 clamps the injection molded part, the anti-slip pad 5 contacts the injection molded part, increasing the friction between the top rod 23 and the injection molded part; when clean water is injected into the dust collection box 6, the dust or impurities inside the cleaning box 1 fall into the dust collection box 6 and are collected by the dust collection box 6.
