Abstract
The invention discloses chip drying treatment equipment in the field of electron component production and particularly relates to a variable-frequency spin dryer. The variable-frequency spin dryer comprises a rack, a rotary drum, a motor and a variable-frequency controller, wherein the rotary drum is arranged on the rack; the rotary drum is driven by the revolving shaft of the motor to rotate; the motor is controlled by the variable-frequency controller to rotate. The variable-frequency spin dryer is characterized in that the motor is an alternating-current motor; the revolving speed of the motor is controlled through the variable-frequency controller by adjusting the frequency of an output power supply; the rotary drum is vertical, and is provided with a dewatering cavity; a nitrogen connecting pipe is arranged above the rotary drum; one end of the nitrogen connecting pipe is arranged in the cavity of the rotary drum, and the other end of the nitrogen connecting pipe is connected with a gas source through an electromagnetic valve; an exhalent siphon is arranged at the central part of the bottom part of the rotary drum. The variable-frequency spin dryer disclosed by the invention has the advantages that operation is reliable, the failure rate is low, the speed is displayed in real time, stepless speed regulating is realized and the like.
Description
Technical field
The present invention relates to a kind of chip equipment for drying in Electronic Components Manufacturing field, a kind of frequency conversion type drier.
Background technology
In semiconductor electronic component production process, for becoming must be cleaned after table top through chemically treated tube core is capable, the tube core after cleaning can assemble sintering after utilizing drier to dry again.There is following point in existing drier:
1) dc motor because adopting, carbon brush machine is easy to wear, usually spark phenomenon occurs, and burns out carbon brush and rotor;
2) can only be rough carry out speed governing by the method for adjustment voltage, cannot realize closed loop program and control rotating speed, speed is unstable;
3) need additional testing the speed and brake assemblies, and fault rate is high.
Because drier is requisite equipment in technological process, its frequency of utilization is high, and the frequent fault effects of equipment has had a strong impact on the normal operation of producing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of frequency converter that adopts to rotate to the ac motor controlling drier, realize stepless accurate speed governing, show rotating speed in real time simultaneously, make drier smooth running, and failure rate is low.
The present invention is achieved by the following technical solutions:
A kind of frequency conversion type drier, comprise frame, swing roller, motor and frequency-variable controller, swing roller is arranged in frame, motor drives swing roller to rotate by rotating shaft, frequency-variable controller controls motor and rotates, it is characterized in that: motor is ac motor, frequency-variable controller controls the rotating speed of motor by the frequency of regulation output power supply, swing roller is vertical, there is dehydration cavity, the top of swing roller is provided with nitrogen tube connector, one end of nitrogen tube connector is arranged in swing roller cavity, the other end is connected with source of the gas by magnetic valve, the bottom center of swing roller is provided with outlet pipe, the alternating current generator that frequency-variable controller controls drier rotates, overcome the defect that the unstable and fault rate of DC motor speed changes, achieve drier stepless speed regulation to control, do further improvement to technique scheme, described frequency-variable controller has motor speed display, timing and speed regulation function.
The present invention has following beneficial effect:
1. reliable, failure rate is low;
2. real-time display speed, realizes stepless speed regulation.
Accompanying drawing illustrates:
Fig. 1 is frequency conversion type drier structure principle chart;
Fig. 2 is frequency conversion type drier electrical schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, content of the present invention is described further:
As shown be frequency conversion type drier structure principle chart, comprise power supply, frequency-variable controller, motor, swing roller, swing roller is arranged in frame, motor drives swing roller to rotate by rotating shaft, frequency-variable controller controls motor and rotates, motor adopts ac motor, ac motor overcomes dc motor, carbon brush machine is easy to wear, usually there is spark phenomenon, burn out the defect of carbon brush and rotor, ac variable frequency speed regulation has reliable, failure rate is low and the advantage realizing stepless speed regulation, frequency-variable controller controls the rotating speed of motor by the frequency of regulation output power supply, swing roller is vertical, there is dehydration cavity, the top of swing roller is provided with nitrogen tube connector, one end of nitrogen tube connector is arranged in swing roller cavity, the other end is connected with source of the gas by magnetic valve, the bottom center of swing roller is provided with outlet pipe.
Claims (2)
1. a frequency conversion type drier, comprise frame, swing roller, motor and frequency-variable controller, swing roller is arranged in frame, motor drives swing roller to rotate by rotating shaft, frequency-variable controller controls motor and rotates, it is characterized in that: motor is ac motor, frequency-variable controller controls the rotating speed of motor by the frequency of regulation output power supply, swing roller is vertical, there is dehydration cavity, the top of swing roller is provided with nitrogen tube connector, one end of nitrogen tube connector is arranged in swing roller cavity, the other end is connected with source of the gas by magnetic valve, the bottom center of swing roller is provided with outlet pipe.
