Background technology
In the diode production, need wafer that make diode be screened, and in the production process of diode wafer, need cut, and can produce some slivers in the cutting process,, sliver need be screened for the ease of producing according to specified size; Existing screening technique is to adopt the manually-operated screen cloth, wave and sieve, sliver is fallen down from sieve screen apertures, this kind method production efficiency is low, all will manually sieve screen cloth when screening at every turn, labour intensity is big, and in screening process, because frequency, speed and the strength of artificial screening are difficult to hold, thereby be easy to cause the damage of wafer.
Summary of the invention
At above-mentioned technical problem, the invention provides a kind of sliver automatic screening device, it need not manually-operated, it can avoid having improved production efficiency because of the people sieves bad phenomenon such as wafer breakage that undue force causes, unfilled corner.
Realize that technical scheme of the present invention is as follows:
Sliver automatic screening device comprises frame, is arranged on the wabbler mechanism that can swing back and forth on the frame, is arranged on and follows the screen cloth that wabbler mechanism is swung together on the wabbler mechanism, and drives the driving mechanism that wabbler mechanism swings back and forth.
Described wabbler mechanism comprises that the upper end is movably connected in two rocking bar groups on the frame, and wherein a rocking bar is connected with the drive end of driving mechanism, and described screen cloth is arranged between two rocking bars.The drive end of driving mechanism drives the wabbler mechanism swing, drives the screen cloth swing that is arranged between two rocking bars simultaneously, thereby can the wafer in the screen cloth be screened.
Described two rocking bar groups comprise two rocking bars separately, the upper end of rocking bar is movably connected on the frame, the lower end of rocking bar links together by connecting rod on the same group, wherein two rocking bar lower ends in one group of rocking bar and another are organized two rocking bar lower ends and are linked together by connecting rod, and described screen cloth is arranged on the connecting rod between the two rocking bar groups.
Described screen cloth comprises the screen cloth framework and is arranged on net on the screen cloth framework, and described screen cloth framework is provided with the holding section, and described holding section is held on the connecting rod between the two rocking bar groups.Screen cloth has the holding section to be held on the connecting rod, and screen cloth can arbitrarily be changed, and the different model wafer can both screen, and is very convenient.
Described driving mechanism comprises drive motors, is connected the reductor of drive motors output, the output shaft of described reductor is connected with drive, the non-circle centre position of drive is provided with joint pin, and the drive rod that is connected with joint pin of an end and wabbler mechanism flexible connection, the other end.Reductor plays the effect of deceleration transmission to drive motors, and the rotation of drive drives the drive rod motion, and the rocking bar that drive rod promotes in the wabbler mechanism swings back and forth.
Described driving mechanism also comprises the speed regulator that drive motors is carried out speed regulating control.Can control the speed of drive motors as required by speed regulator, thereby also just control the frequency that screen cloth sieves, effectively control and considered the sieve effect.
The below of described screen cloth is provided with receiving hopper.The crystal grain that sifts out by screen cloth finally falls into reservoir bag by the material receiving port of receiving hopper lower end, reaches full-automatic unmanned purpose of standing fast at work.
Adopted such scheme, speed regulator is controlled drive motors work and it is carried out speed governing, the driving force of drive motors passes to drive by reductor, and drives the rocking bar that drive rod drives in the wabbler mechanism and move back and forth, thereby realizes the screening function of screen cloth.The present invention need not manually-operated, it can avoid having improved production efficiency because of the people sieves bad phenomenon such as wafer breakage that undue force causes, unfilled corner; In addition by changing the screening requirement that different screen clothes can satisfy various model crystal grain.
