Problems solved by technology

Molding compound dust will be generated during laser marking. At present, the dust is sucked away by a strong exhaust type vacuum cleaner and discharged into the general dust discharge pipe. The dust discharge port of each device is connected to the general pipe. When a certain device does not The vacuum cleaner stops working during operation, and the dust discharged by the vacuum cleaner of other equipment will flow back into the stopped equipment along the pipe, affecting the cleanliness of the laser lens, and the dust will be discharged into the air from the air inlet along the vacuum cleaner pipe, seriously affecting the production workshop. The degree of purification, while the dust discharged into the air directly affects the health of the operator

Abstract

The invention discloses a dedusting air door automatic switch device and a dust collector with the same. The dedusting air door automatic switch device comprises a wind chamber formed by an upper cover plate, a lower cover plate and a plurality of side plates in a surrounding mode. An upper air vent is arranged on the upper cover plate. A lower air vent is arranged on the lower cover plate. The upper air vent is connected with a tubular shape upper connecting end. The lower air vent is connected with a tubular shape lower connecting end. A wind board capable of blocking an air vent of the lower connecting end is arranged at one end, placed inside the wind chamber, of the lower connecting end. In addition, the wind board is capable of rotating within an included angle formed by a horizontal plane and a vertical plane. An air-out pipeline of the dust collector is provided with the dedusting air door automatic switch device. The dedusting air door automatic switch device is capable of preventing dust backflow effectively, beneficial to body health of operators, and reduces damage frequency of the dust collector and particularly solves the problem of the dust backflow.

Description

technical field [0001] The invention relates to dust removal technology, in particular to an automatic switch device for a dust removal damper and a vacuum cleaner equipped with the device. Background technique [0002] In the semiconductor packaging process, laser marking on the surface of the IC plastic package is an essential process. Molding compound dust will be generated during laser marking. At present, the dust is sucked away by a strong exhaust type vacuum cleaner and discharged into the general dust discharge pipe. The dust discharge port of each device is connected to the general pipe. When a certain device does not The vacuum cleaner stops working during operation, and the dust discharged by the vacuum cleaner of other equipment will flow back into the stopped equipment along the pipe, affecting the cleanliness of the laser lens, and the dust will be discharged into the air from the air inlet along the vacuum cleaner pipe, seriously affecting the production works...
