Machine is connected, and motor lower end is connected by ring flange with L-type support frame inner bottom, the circular gear and rack bar
Gear engagement is carried out, is machined with through-hole on the sucker two, and through-hole is connected by ring type seal with bolt rod, the tooth
Bar inner end is machined with pin hole, and bolt rod is provided on pin hole, and the L-type support frame inner face is machined with sliding slot, and
Rack bar is installed, in actual use, after pcb board is completed for printing, user of service holds turntable, and carries out again on sliding slot
Rotation, turntable rotate to drive hollow pipeline to move up, hollow pipeline move up drive sucker one and bearing block to
Upper movement is moved up when bearing block is moved upwards up to L-type support frame inner tip so as to cause hollow pipeline stopping, into
And hinder the rotation of hollow pipeline, then turntable be rotated further drive threaded rod rotation, threaded rod rotate to move up, into
And be separated with hollow pipeline, outside air is in contact with one inner air of sucker at this time, and then the suction of sucker one disappears, from
And sucker one is caused to be separated with pcb board, then user of service starts motor, and electric motor operation drives shaft rotation, shaft
Rotation drives circular gear rotation, is engaged because circular gear carries out gear with rack bar, circular gear rotation band moving teeth
Bar is moved forward along sliding slot, and rack bar, which moves forward, drives bolt rod to move forward, and bolt rod is moved forward while being driven
Support plate and sucker two move forward, and support plate, which moves forward, drives pcb board to move forward, and conjunction is moved forward in support plate
When right position is set, motor out of service, then user of service be displaced outwardly rack bar, rack bar is displaced outwardly can be with bolt rod phase
Separation, then user of service holds bolt rod, and moves right, and to realize that bolt rod is separated with sucker two-phase, and then causes
The suction of sucker two disappears, and realizes the function of fast quick-detach.
5. a kind of stencil printer according to claim 1, it is characterised in that：In the protection mechanism, the magnetite
Stick outer end face is connected with spring protective cloth, and L-type steering block, the L-type steering block setting are equipped on the spring protective cloth
In magnetite stick outer end, the magnetite stick and L-type steering block are assemblied on base board, and the spring protective cloth is mounted on
Base board inner bottom, L-type steering block outer end are fixed with connecting plate, the connecting plate lower end by ring flange with it is flexible soft
Pipe is connected, and the bellows is assemblied in base board inner bottom, and base board inner end top passes through sliding rail and sliding shoe
It is connected, the sliding shoe is mounted on lead screw, and the sliding shoe inner end is connected with spring two, and two lower end of the spring is equipped with
Movable pulley, the movable pulley are arranged in bottom plate upper surface, and the bottom plate upper end is connected with spring three, and the spring three is assemblied in bottom
Seat board inner tip, the movable pulley and bottom plate are arranged inside base board, and the lead screw rear end passes through bearing and pedestal
Plate inner wall is connected.
6. a kind of stencil printer according to claim 5, it is characterised in that：The connecting plate lower end face is fixed with guiding
Bar, the base board inner bottom offers pilot hole, and guide rod is equipped on pilot hole, and guide rod be assemblied in it is flexible soft
On the outside of pipe, the bellows lower end is connected by tracheae with inflator, and inflator by ring flange with inside base board
Bottom end is connected, and in actual use, user of service starts inflator, and inflator work drives air flowing, then extraneous empty
Gas is entered by inflator and tracheae inside bellows, and then bellows inflation starts to extend, bellows elongated
Dynamic connecting plate moves up, and connecting plate, which moves up, drives L-type steering block to move up, and L-type steering block moves up drive magnetic
Stone stick moves up, while L-type steering block is moved up and can be stretched to spring protective cloth, is moved up in magnetite stick
When to suitable position, inflator out of service, then user of service holds two magnetite sticks, and moves inward, two magnetites
Stick moves inward to stretch spring protective cloth again, while two magnetite sticks move inward to carry out each other
It is connected, realizes the function of protection, avoid falling into for dust.
7. a kind of stencil printer according to claim 5, it is characterised in that：The sliding shoe lower end processing is fluted,
And inside grooves top is connected with spring two, the bottom plate left and right ends are connected by sliding rail with base board inner wall, described
Bottom plate cross section is trapezoidal, and the bottom plate lower face is pasted at least two suction trays, the lead screw by ball nut pair with
Sliding shoe is connected, and the lead screw front end is machined with square aperture slot, and rectangular connecting rod is equipped on square aperture slot, and side
Shape connecting rod is fixedly arranged at the front end with handle, and in actual use, user of service holds handle, and moves backward, and handle moves backward
Rectangular connecting rod is driven to move backward, rectangular connecting rod is moved backward hence into inside square aperture slot, then user of service
Handle is held, and is rotated, handle rotates to drive lead screw to rotate, because lead screw passes through ball nut pair and sliding shoe phase
Connection, so lead screw rotation drives sliding shoe to be moved forward along sliding rail, sliding shoe, which moves forward, drives spring two to move forward,
Spring two, which moves forward, drives movable pulley to move forward, and movable pulley moves forward to be separated with bottom plate, at this time in spring three
Under the action of drive bottom plate to be moved up along sliding rail, be separated so as to cause bottom plate and ground, while movable pulley is in spring two
Under the action of move down, and then movable pulley and ground is caused to touch, then to base board under the action of spring two
It is lifted, then user of service stops operating lead screw, and moves forward handle, so as to cause rectangular connecting rod and square aperture
Slot is separated, and realizes the fixed function of support, and also allow for moving.
