Description
Technical field
The present invention relates to a kind of cam-types of liquid crystal display pcb board connector to push mechanism for testing.
Background technique
Liquid crystal display pcb board connector needs to test it after producing, and is powered and detects whether it can light liquid
Crystalline substance screen.
Liquid crystal display pcb board connector is tested using special pushing mechanism for testing in industry at present, this pushing
Mechanism for testing is usually made of the pressure head drive mechanism of the testing pressure head and driving testing pressure head movement that are furnished with contact, test pressure
Head connects power supply by electric wire.And in existing testing agency, the manually or mechanically hand after being completed takes for convenience
Blowing, pressure head drive mechanism are to realize the translation of testing pressure head with two sets of cylinder driving mechanisms and push two to act, drawback
It is that excessively high mechanism complexity, cost, inefficiency, control are cumbersome.
Summary of the invention
Object of the present invention is to: the cam-type for providing a kind of liquid crystal display pcb board connector pushes mechanism for testing, the mechanism structure
It simplifies, is capable of translation and the pressing action of a set of movement completion testing pressure head, reduces motion profile, improve working efficiency, reduce
Manufacturing cost.
The technical scheme is that a kind of cam-type of liquid crystal display pcb board connector pushes mechanism for testing, including base
And testing pressure head, it is characterised in that it further include that lower air cylinder, the first support plate and the second support plate, lower air cylinder are fixed on base,
The mandril of lower air cylinder is connected for driving the first support plate in vertical direction activity with the first support plate, and testing pressure head is fixed on second
On support plate, which is movably connected below the first support plate by guided in translation mechanism, while being pivoted and being set on the second support plate
There is rolling element, and be fixed with the cam bit with rolling element cooperation to drive the opposite first support plate translation of the second support plate on base,
And the dynamic clamping head and quiet clamping head resetted for the translation of the second support plate is equipped in guided in translation mechanism.
Further, heretofore described guided in translation mechanism includes the lug fixed or be integrally provided on the first support plate
Seat, the horizontal guide being fixed on trunnion cup and the translational block being placed on by guide hole in horizontal guide, translational block and the second support plate
Fixed or integrated design, dynamic clamping head and quiet clamping head is spring, is set in horizontal guide, and support be located at trunnion cup and translational block it
Between.
Further, heretofore described guided in translation mechanism is two, and bilateral symmetry is set to the first support plate two sides.
Further, it is fixed with vertical guide rail on heretofore described base, and fixes or be integrally formed on the first support plate
With the vertically-guided sliding block of vertical guide rail cooperation.
Further, heretofore described vertical guide rail is two, and is symmetrically arranged in the left and right of the lower air cylinder
Two sides, and the vertically-guided sliding block is two pieces, is cooperated respectively with two vertical guide rails.
Further, the bottom of heretofore described first support plate is equipped with horizontal guide rail, and the second support plate is equipped with and water
The horizontally-guided sliding block of level gauge cooperation.
Further, heretofore described horizontal guide rail is two, and is symmetrically arranged in the left and right of the testing pressure head
Two sides, and the horizontally-guided sliding block is two pieces, is cooperated respectively with two horizontal guide rails.
Further, heretofore described rolling element is rolling bearing or idler wheel.
Further, upper bumper and lower bumper are fixed on heretofore described base.Mechanism of the present invention is in reality
It is mostly installed at when use on the board of test equipment, base needs are fixed with board, and the addition effect of upper and lower buffer is just
It is the vibration that base and board are subject to when reducing lower air cylinder work.
Further, there is the tapered plane to offset with rolling element or oblique cambered surface on heretofore described cam bit and be connected in tiltedly
Vertical plane below plane or oblique cambered surface.Tapered plane or the effect of oblique cambered surface mainly drive rolling element and the second support plate can be under
Translation activity is done with respect to the first support plate while drop, so that entirety is moved diagonally or oblique arc trajectory.And the vertical plane of lower section is then true
It protects the second support plate finally to move vertically, testing pressure head is vertically contacted with liquid crystal display pcb board connector, improve contact
Stability.
It is of the invention that the specific working principle is as follows:
Firstly, base is fixed by bolts to the test equipment board of existing liquid crystal display pcb board connector, testing pressure head passes through
Power supply in electric wire connecting test equipment.
Liquid crystal display pcb board connector to be detected is placed in below mechanism, lower air cylinder, lower air cylinder top rod driving are started
First support plate and the second support plate vertically decline together, after the rolling element on the second support plate contacts cam bit, act in cam bit
Lower second support plate overcomes the elastic force of spring to translate with respect to the first support plate, whole to walk a diagonal line or oblique arc along cam bit surface tracks
Whether line movement, contacts testing pressure head with the liquid crystal display pcb board connector of lower section, can be by point by observation liquid crystal display
It is bright to detect connector product specification.
After being completed, lower air cylinder mandril is retracted, and testing pressure head is made jointly in the elastic force of lower air cylinder pulling force and spring
Under, initial position is returned to along cam bit surface tracks, testing pressure head is made not have intersection with detected product in the horizontal direction,
Convenient artificial or manipulator picks and places material.
During this, when rolling element under lower air cylinder drives contacts cam bit, lower bumper weakens base and test
The vibration of equipment board, then when lower air cylinder driving mandril drives the first support plate and the second support plate to retract, upper bumper weakens
The vibration of base and test equipment board.
The invention has the advantages that
1) translation and the pressing action of a set of movement completion testing pressure head are capable of in mechanism of the invention design, are realized and are originally needed two
The function that the cooperation of cylinder driving mechanism is realized is covered, not only structure is more simplified, manufacturing cost is reduced, and manipulation is simpler,
The motion profile for reducing testing pressure head, improves work efficiency, and accelerates product testing speed.
2) it is carried respectively to improve the first support plate and second in mechanism of the invention by increasing vertical guide rail and horizontal guide rail
The stationarity of plate movement, so that mechanism overall operation is more steady reliable.
3) tapered plane or oblique for driving the opposite first support plate translation of the second support plate is devised on cam bit of the invention
Except cambered surface, the vertical plane being connected in below tapered plane or oblique cambered surface is also further devised, it is ensured that the second support plate is finally done vertically
Movement, enables testing pressure head vertically to contact with liquid crystal display pcb board connector, improves contact stabilization.
