Abstract
The utility model relates to a light modulator for an automatic recognition system of a press welder, which is composed of a camera gun, optical fiber, a bulb, a light modulator, work areas and workpieces. The camera gun is toward the work areas and the workpieces. An optical fiber head at one end of the optical fiber jets out light spots to the workpieces. An optical fiber head at the other end of the optical fiber is toward the bulb. The light intensity of the bulb is modulated by the light modulator so as to meet the requirements of illuminance in the work areas and in an automatic identification system. The utility model has the advantages of simple structure, low cost, simple and reliable operation, and easy maintenance.
Description
The utility model relates to semiconductor device production equipment technical field, the light modulating device that particularly a kind of press welder automatic recognition system is used.
Produce in the special equipment at semiconductor device, very complicated illumination adjustments device is all adopted in the illumination of the automatic recognition system of press welder.The required illumination of the camera gun of automatic recognition system is from Optical Fiber Transmission.The luminous flux that light source enters optical fiber is controlled by the shadow shield that stepping motor drives, and the instruction of stepping motor is from the computer of main frame, and through manually with keyboard output being set.Light source uses the bulb that power is very big, and the electronic circuit of control step motor and inductor are toasted by bulb heat energy, are easy to generate fault.Maintenance is inconvenient, and the method for setting the regulating and controlling illumination on keyboard improves the machine cost, the program complexity, safeguard and operating cost all high.
The light modulating device that the purpose of this utility model is to provide a kind of cheap and simple, do not need the press welder automatic recognition system of complicated electronic circuit and Step-motor Control to use.
The purpose of this utility model is achieved in that the light modulating device that a kind of press welder automatic recognition system is used, comprise camera gun, optical fiber and two ends optical fiber head thereof, bulb, service area, workpiece, one end optical fiber head is facing to bulb, and the rayed that other end optical fiber head sends is on the service area, camera gun is facing to the workpiece on the service area, described bulb is connected to dimmer, regulates the brightness of bulb by potentiometer.
Advantage of the present utility model is simple in structure, with low cost, and is easy and simple to handle, reliable, and maintenance easily.
Fig. 1 is the structural representation of an embodiment of the utility model.
By following embodiment the utility model is further elaborated.
Fig. 1 is the light modulating device that a kind of press welder automatic recognition system of embodiment of the utility model is used, form by camera gun 1, optical fiber 2, optical fiber head 3, optical fiber head 4, bulb 5, dimmer 6, potentiometer 7, service area 8 and workpiece 9, the illumination that the camera gun 1 of automatic recognition system is required, from optical fiber head 3, the light source of optical fiber 2 is from bulb 5, and the luminous intensity of bulb 5 is regulated by dimmer 6.Dimmer 6 adopts the electronic circuit of known technology, regulates the luminous intensity that voltage, the electric current of supplying with bulb 5 are controlled bulb 5 by potentiometer 7 and knob thereof.When press welder automatic recognition system camera gun 1 required illumination is regulated,, observe the illumination and shown satisfied the getting final product of effect of TV screen of workpiece 9 by regulating dimmer 6.
