Step.However, existing Antisticking air blowing type integrated circuit testing jig still has several drawbacks place, existing equipment is often logical
Crossing manual operation pushes thimble that chip roof fall is not only easily led to wafer damage, and the degree of automation is not high.
Utility model content
The purpose of this utility model is that: in order to solve the problem of that the degree of automation is not high and chip rapid wear, provide anti-sticking
Expect air blowing type integrated circuit testing jig.
The technical solution adopted in the utility model is as follows:
Antisticking air blowing type integrated circuit testing jig, including pressing plate, medium position offers plunger shaft in the pressing plate,
The plunger shaft bottom and be located at pressing plate in be also provided with two wind chambers, sliding sleeve is connected to piston, the work in the plunger shaft
Plug top is fixedly connected with metal block, and two sides are symmetrically welded with side plate at the top of the pressing plate, passes through axis between two side plates
It holds and is rotatably connected to shaft, and be welded with eccentric wheel at shaft medium position.
Wherein, limited aunular sheet is welded at the plunger shaft top edge, and the outer diameter of limited aunular sheet and piston external diameter are big
It is small equal.
Wherein, described two wind chambers run through the pressing plate, and two wind chambers are symmetrical about the vertical center line of plunger shaft.
Wherein, described shaft one end is driven by transmission shaft through side plate and with the driving motor for being fixed on pressing plate upper surface
Connection.
Wherein, the eccentric wheel is mutually perpendicular to shaft.
Wherein, the piston base two sides are connect by symmetrically arranged telescopic rod with plunger shaft bottom inner surface wall, and are stretched

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Referring to Fig.1-3, Antisticking air blowing type integrated circuit testing jig, including pressing plate 1, medium position opens up in pressing plate 1
There is a plunger shaft 111,111 bottom of plunger shaft and be located in pressing plate 1 and be also provided with two wind chambers 112, is slidably socketed in plunger shaft 111
There is piston 7, be fixedly connected with metal block 8 at the top of piston 7,1 top two sides of pressing plate are symmetrically welded with side plate 2, between two side plates 2
It is rotatably connected to shaft 3 by bearing, and is welded with eccentric wheel 4 at 3 medium position of shaft.
Limited aunular sheet 5, and the outer diameter of limited aunular sheet 5 and 7 outer diameter size phase of piston are welded at 111 top edge of plunger shaft
Deng two wind chambers 112 run through pressing plate 1, and two wind chambers 112 are symmetrical about the vertical center line of plunger shaft 111,3 one end of shaft
It is sequentially connected by transmission shaft through side plate 2 and with the driving motor 6 for being fixed on 1 upper surface of pressing plate, eccentric wheel 4 and 3 phase of shaft
Mutually vertical, 7 two sides of the bottom of piston are connect by symmetrically arranged telescopic rod 10 with 111 bottom inner surface wall of plunger shaft, and telescopic rod
Reset spring 9 is socketed with outside 10.
Symmetrically arranged two telescopic rods 10 are for ensuring that it is steady that piston 7 is able to maintain in moving process in the vertical direction
Fixed, reset spring 9 is prepared for resetting to piston 7 for compressed air next time, 8 upper surface of metal block and eccentric wheel 4
