Description
Technical field
The utility model relates to a kind of screening plant, is specifically related to a kind of sliver automatic screening device that sliver in the wafer production processes is screened.
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,, need sliver 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 want manual work to sieve screen cloth when screening at every turn, and 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
To above-mentioned technical problem, the utility model provides a kind of sliver automatic screening device, and 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.
The technical scheme that realizes the utility model is following:
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.
Said 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 said 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.
Said 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 through 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 through connecting rod, and said screen cloth is arranged on the connecting rod between the two rocking bar groups.
Said screen cloth comprises the screen cloth framework and is arranged on the net on the screen cloth framework, and said screen cloth framework is provided with the holding section, and said 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.
Said driving mechanism comprises drive motors, is connected the reductor of drive motors output; The output shaft of said 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.
Said 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 through speed regulator, thereby also just control the frequency that screen cloth sieves, effectively control and considered the sieve effect.
The below of said screen cloth is provided with receiving hopper.The crystal grain that sifts out through screen cloth finally falls into reservoir bag through 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 through 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 utility model 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 through changing the screening requirement that different screen clothes can satisfy various model crystal grain.
