[0002] Dry ice cleaning technology is a mature and widely used cleaning technique, especially in industrial production where convenient dry ice cleaning is particularly needed. Dry ice cleaning involves using high-pressure air to spray dry ice particles from a dry ice cleaning machine onto the work surface to be cleaned. The physical reaction caused by the temperature difference causes different substances to detach at different contraction rates. Currently, dry ice mold cleaning is mainly done manually. However, due to the high temperature of the molds, operators are prone to burns when working at close range, and two people are required to operate the machine simultaneously, which consumes manpower and cannot guarantee the cleaning effect or time.

The moving platform 3 is mounted on the lifting base 2, the dry ice gun 1 is mounted on the moving platform 3, and the stop device 4 is located on the front side of the moving platform 3.

[0024] This utility model discloses an automatic cleaning device for semiconductor packaging molds, including an electrical control system, a dry ice gun 1, and a lifting base 2, a moving platform 3, and a stop device 4, all electrically connected to the electrical control system. Powered and controlled by the electrical control system, the lifting base 2 moves the moving platform 3 and the dry ice gun 1 upwards. The stop device 4 detects the relative position of the moving platform 3 and the mold, thereby triggering the lifting base 2 to stop moving and the moving platform 3 to move the dry ice gun 1 within the mold, performing dry ice cleaning on the mold. This automatic cleaning device reduces manual intervention steps, increases safety, and improves the quality and efficiency of dry ice mold cleaning.

[0025] The mobile platform 3 includes a housing 31, a cover 32, a moving device 33, and a mounting frame 34. The housing 31 is mounted on the lifting base 2, and the cover 32 covers the housing 31. The moving device 33 is located inside the housing 31. A sliding groove 35 is provided on the front side of the housing 31. The mounting frame 34 passes through the sliding groove 35 and is connected to the moving device 33. The dry ice gun 1 is mounted on the mounting frame 34. The moving device 33 includes an X-axis slide rod 331, a Y-axis slide rod 332, a first moving seat 333, a second moving seat 334, a connecting frame 335, and four guide rods 336. The X-axis slide rod 331 is mounted inside the housing 31. The connecting frame 335 is perpendicular to the X-axis slide rod 331 and positioned above it. The four guide rods 336... The guide rods 336 are respectively located on the left and right sides inside the housing 331. The two guide rods 336 are respectively clamped on the upper and lower sides of either end of the connecting frame 335. The first movable seat 333 is slidably mounted on the X-axis slide rod 331 and connected to the connecting frame 335. The Y-axis slide rod 332 is located on the connecting frame 335. The second movable seat 334 is slidably mounted on the Y-axis slide rod 332. The mounting frame 34 is connected to the second movable seat 334. The four guide rods 336 clamp and restrict the movement of the connecting frame 335. The first movable seat 333 moves along the X-axis slide rod 331 and drives the connecting frame 335 to move. The second movable seat 334 moves along the Y-axis slide rod 332 on the connecting frame 335, thereby driving the mounting frame 34 to move in the plane.

[0026] The first movable seat 333 and the second movable seat 334 have the same structure. The first movable seat 333 includes a seat body 337, rollers 338, a servo motor 339, and two clamping rollers 330. The seat body 337 is slidably mounted on the X-axis slide rod 331.

The rollers 338 are connected to the output end of the servo motor 339 and abut against the X-axis slide rod 331. The servo motor 339 ensures the movement speed. The rollers 338 and the two clamping rollers 330 respectively clamp the X-axis slide rod 331, improving the stability of operation and ensuring the mold clearing effect.

[0027] The mounting bracket 34 includes a mounting component 341, two telescopic rods 342, two pulleys 343, and a sliding rail 344.

On one side of the sliding groove 35, two pulleys 343 are slidably disposed within the sliding rail 344. The dry ice gun 1 is disposed on the mounting member 341. When the moving device 33 pushes the mounting member 341 out of the housing 31, the mounting member 341 is suspended in the air and experiences a large force. The two telescopic rods 342 provide a certain support or pulling force to the mounting member 341 to prevent the mounting member 341 from being damaged due to excessive force. At the same time, they can also share part of the weight to prevent the automatic cleaning equipment from tipping over.

[0028] The mounting bracket 34 also includes a reinforcing block 36, on which two connecting slots 37 are provided. The two telescopic rods 342 are respectively inserted into the two connecting slots 37. One end of each connecting slot 37 is provided with a snap-fit ​​groove.

The snap-fit ​​block 347 snaps into the snap-fit ​​groove. The side of the reinforcing block 36 facing the cover 32 is provided with at least two ball bearings 38. The reinforcing block 36 shares part of the weight of the dry ice gun 1, and the ball bearings 38 can convert the sliding friction between the reinforcing block 36 and the cover 32 into rolling friction, thereby improving the smoothness of the movement of the dry ice gun 1.

[0029] The dry ice gun 1 includes a gun rod 11, a nozzle 12, a limiting ring 13, a threaded tube 14, and a threaded sleeve 15. The gun rod 11 is mounted on the mounting bracket 34. The threaded sleeve 15 passes through one end of the nozzle 12. The limiting ring 13 is located inside the threaded sleeve 15 and connected to the nozzle 12. The threaded tube 14 is connected to the gun rod 11. The threaded sleeve 15 and the threaded tube 14 are threadedly connected. Through the quick-connect of the threaded sleeve 15 and the threaded tube, the nozzle 12 with a single nozzle or a double nozzle can be quickly replaced, making it more applicable to a wider range of scenarios and convenient to assemble and disassemble.

[0030] The stopping device 4 includes one of a laser sensor, an infrared sensor, and a camera. The electronic control system includes a power supply and a control device, and the control device includes an SMT32.

[0031] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
