Description

Technical Field

[0001] This utility model relates to the technical field of organic coating spin coating equipment, specifically an organic coating spin coating equipment with adjustable atomization effect. Background Technology

[0002] An adjustable atomization organic coating spin coating device is a novel coating preparation equipment that integrates ultrasonic atomization technology and precision spin coating process. It is specifically designed to address the pain points of traditional spin coating equipment, such as fixed atomization effect, low material utilization, and poor coating adaptability. This equipment innovatively combines a precise atomization adjustment system with a high-speed spin coating mechanism, enabling flexible control of the atomization effect of organic coatings from micro-nano to micron scales. Simultaneously, it relies on centrifugal force to achieve uniform coating spread, making it widely applicable to fields with stringent coating quality requirements, such as microelectronics, optoelectronics, new energy, and precision device manufacturing. However, existing adjustable atomization organic coating spin coating devices still have certain shortcomings. While traditional electrostatic spin coating equipment with adjustable atomization effects can be used effectively, the workpiece grounding of traditional electrostatic spin coating equipment often relies on a single contact point. This can easily lead to excessive grounding resistance and breakage of the electrostatic circuit due to paint residue or loose contact. This not only reduces the paint adsorption efficiency but may also cause safety hazards due to static electricity accumulation. At the same time, the lack of grounding protection can result in disordered adsorption of charged droplets and low paint utilization, which often troubles users. Utility Model Content

A grounding copper wire 202 is fixedly installed on the fixed base 201, and the fixed base 201 is fixedly installed to the chassis 101 by fixing bolts 104.

[0015] The clamping mechanism 3 includes a drive motor 301, a drive shaft 302, a rotating drum 303, a fixing plate 304, a suction cup 305, an air supply pipe 306, a hydraulic cylinder 307, a placement plate 308, and a telescopic rod 309. The drive motor 301 is fixedly installed on the housing 101, and the drive shaft 302 is fixedly installed at the output end of the drive motor 301. The drive shaft 302 is connected to the housing 101 by a bearing, and the drive shaft 302 is hollow.

[0016] A rotating drum 303 is fixedly installed on the drive shaft 302. Six sets of fixing plates 304 are provided on the rotating drum 303, and the fixing plates 304 are fixedly installed forward on the rotating drum 303. Two sets of suction cups 305 are fixedly installed on the fixing plates 304.

[0017] The drive shaft 302 is equipped with an air supply pipe 306. One end of the air supply pipe 306 is connected to an external air pump, and the other end of the air supply pipe 306 is fixedly connected to a suction cup 305.

[0018] A hydraulic cylinder 307 is installed inside the chassis 101, and the hydraulic cylinder 307 is fixedly installed on the inner bottom surface of the chassis 101. A placement plate 308 is fixedly installed on the output end of the hydraulic cylinder 307.

[0019] The chassis 101 is equipped with four sets of telescopic rods 309. The telescopic rods 309 are fixedly installed to the inner bottom surface of the chassis 101, and the output end of the telescopic rods 309 is fixedly installed to the bottom surface of the placement plate 308.

[0020] Working Principle: When using an organic coating spin coating device with adjustable atomization effect, first open the switch door 103 of the machine casing 101, place the workpiece to be coated on the placement plate 308, and start the hydraulic cylinder 307 through the control panel 105 to drive the placement plate 308 to rise to the appropriate height. The telescopic rod 309 extends and retracts synchronously to ensure the stability of the placement plate 308. At the same time, an external air pump supplies air to the suction cup 305 through the air supply pipe 306 inside the drive shaft 302. The suction cup 305 generates negative pressure to adsorb the workpiece, achieving mechanical fixation. In addition, the grounding copper wire 202 on the fixing base 201 contacts the connecting copper wire 205, and the clamp 204 at the end of the connecting copper wire 205 clamps the workpiece, forming a conductive circuit between the workpiece and the ground, providing grounding protection for electrostatic coating. Subsequently, paint and compressed air are introduced into the atomizing nozzle 207 through the air inlet pipe 206, and the air pressure parameters are adjusted by the control panel 105 so that the atomizing nozzle 207 breaks the paint into uniform droplets; at the same time, the two sets of electrostatic field generators 208 on the bottom surface of the machine box 101 are started to generate a stable high voltage electrostatic field, so that the atomized paint droplets are charged. Simultaneously, the drive motor 301 is started, driving the rotating drum 303 to rotate via the drive shaft 302. The fixed plate 304 on the rotating drum 303 rotates synchronously with the rotating drum 303, thereby causing the workpiece adsorbed by the suction cup 305 to perform a circular motion. Under the action of electrostatic force, the charged paint droplets are precisely adsorbed and evenly attached to the surface of the rotating workpiece, achieving all-round spin coating coverage. By sliding the position of the fixed seat 201 and adjusting the air pressure of the air inlet pipe 206, the atomization effect and coating range can be flexibly changed to adapt to the coating requirements of different workpieces, thus completing a series of tasks.
