Dicing machine

Abstract

The invention provides a dicing saw. The dicing saw comprises a spindle, a cutting knife which is fixedly connected with the spindle and is driven by the spindle to rotate, and a waterproof and dustproof device which is used for preventing water or dust from entering the dicing saw in the rotating process of the cutting knife. The dicing saw further comprises two guide grooves which extend in the Y-axis direction and are parallel to each other, a fixed frame surrounded by two roller shutter covers connected with the tail ends of the two guide grooves, a movable frame which is located inside the fixed frame and can slide in the guide grooves back and forth, and a PVC thin film, wherein one end of the PVC thin film is fixedly connected with the movable frame, and the other end of the PVC thin film is contained in the roller shutter covers in a winding mode. The waterproof and dustproof device comprises a Y-axis waterproof and dustproof structure and a Z-axis waterproof and dustproof structure. The Y-axis waterproof and dustproof structure comprises waterproof rubber tapes which are installed in the guide grooves so as to prevent water or dust from entering the guide grooves. The Z-axis waterproof and dustproof structure comprises a Z-axis motion part located below the movable frame and a Z-axis water shield with one end being fixedly connected with the Z-axis motion part and the other end being fixedly connected with the movable frame.

Description

technical field [0001] The invention relates to a dicing machine with a waterproof and dustproof device, in particular to a dicing machine capable of waterproofing and dustproofing both in the Y-axis direction and in the Z-axis direction. Background technique [0002] The current dicing machine mainly uses PVC film rolls to be heat-treated and shaped after forming. One end of the PVC film is installed on the fixed part, and the other end is installed on the moving part, and then the film is kept shrinking by its own elasticity after shaping. However, such a structure has some obvious defects: when the device moves up and down along the Z axis, as the Z axis moves higher, the gap between the film and the waterproof board will be larger, and water droplets and mist will pass through. The gap splashes to the parts that need to be waterproof, which affects the use of the equipment; moreover, with the increase in the number of uses and the impact of cutting wastewater, the elasti...

Problems solved by technology

However, such a structure has some obvious defects: when the device moves up and down along the Z axis, as the Z axis moves higher, the gap between the film and the waterproof board will be larger, and water droplets and mist will pass through. The gap splashes to the parts that need to be waterproof, which affects the use of the equipment; moreover, with the increase in the number of uses and the impact of cutting wastewater, the elasticity of the PVC film roll will gradually decrease, so that normal shrinkage cannot be guaranteed during processing, which affects the normal operation of the equipment.
