Description
Technical field
The present invention relates to a kind of sealed in unit ejector pin mechanism.
Background technology
At some sealed in units, in die Bonder and RFID (REID) equipment, often all need to pierce through film (being used for fixing chip) and with the chip jack-up on the film with thimble, the suction nozzle (the suction nozzle internal holes can produce negative pressure) that is positioned at like this directly over the chip is easy to draw chip.Because present technology and level of processing are more and more higher, simultaneously in order to save cost, do chip more and more littler, this just require thimble must place chip center under, guarantee that simultaneously thimble motion do not tilt, make thimble just in time push up the center of chip, film and jack-up chip are pierced through in realization, make chip break away from the restriction of film basically, the assurance suction nozzle can be drawn chip smoothly, and thimble is got back to initial position then.
Summary of the invention
It is good that the technical problem to be solved in the present invention provides a kind of guidance quality, can prevent the ejector pin mechanism that thimble tilts.
For solving the problems of the technologies described above, ejector pin mechanism of the present invention comprises thimble, thimble rod, the thimble rod seat of honour, thimble Connection Block, thimble rod movable plate, following of thimble rod, lever, cam, back-moving spring, lead, motor; Described motor is fixed on the thimble Connection Block, and motor shaft and cam connect firmly; Lever and thimble Connection Block flexibly connect, and can rotate with respect to the thimble Connection Block; One end of lever contacts all the time with cam, and the other end contacts all the time with the thimble rod movable plate; Thimble rod movable plate and thimble rod connect firmly; Following of the thimble rod and the thimble rod seat of honour connect firmly with the thimble Connection Block respectively; The thimble rod top and the thimble rod seat of honour flexibly connect, following flexible connection of bottom and thimble rod, and thimble rod can be made axially reciprocating; Lead is fixed on the thimble rod movable plate, and back-moving spring is assemblied on the lead, and lead can move reciprocatingly in the corresponding aperture of thimble Connection Block; Thimble is fixed on the end of thimble rod.
When motor rotated, motor shaft drove the cam rotation.Because the wobbler action of cam forces the lever rotation, jack-up thimble rod movable plate moves upward thereby drive thimble.The height of thimble jack-up maximum can just make chip break away from the restriction of film basically with chip from film jack-up; Cam is rotated further, and cam off-centre diminishes, and this moment, the thimble rod movable plate resetted under the effect of the deadweight of the spring force of back-moving spring and lever, and lever is got back to initial position, finishes the action of a chip jack-up.
The present invention relies on the rotation of cam to drive lever and rotates, thereby makes thimble rod make axially reciprocating.Because in the thimble rod axial motion process, the thimble rod seat of honour, following of thimble rod, lead and thimble Connection Block play guide effect, the good stability of thimble rod axially reciprocating, thimble is difficult for tilting.
Described thimble adopts the thimble folder to clamp; Thimble is entrained with four breach, and its lower end is assemblied in the upper end stop portion of thimble rod, and tightens up with thimble back of the body cap; Described thimble back of the body hatband has inner cylinder face targeting part and internal conical surface targeting part; The face of cylinder targeting part of thimble rod upper end is assemblied in the inner cylinder face targeting part inside of thimble back of the body cap; The outer conical surface targeting part of thimble folder is assemblied in the internal conical surface targeting part inside of thimble back of the body cap, and the female thread portion on the while thimble back of the body cap is connected with the male thread portion on the thimble rod.With thimble rod and the separately design of thimble folder, can both process and guarantee machining accuracy easily for every; Because the thimble folder is a consumable accessory, be convenient to maintenance and replacing, prevent the whole waste of thimble rod.Thimble is entrained with four breach, helps guaranteeing more evenly to clamp thimble, prevents that thimble from tilting.Thimble rod upper end cooperates with thimble back of the body cap by face of cylinder targeting part, and the thimble folder is carried on the back cap by taper seat targeting part and thimble and cooperated, be easy to guarantee thimble is carried on the back cap, thimble presss from both sides and the thimble rod three between the axiality requirement.
Following of described thimble rod is fixed together with bolt and thimble Connection Block by articulation hole, help these two combination processing, guarantee the axiality requirement of linear bearing up and down easily, improved the guiding accuracy of thimble rod, also help when assembling this location of two with reset, improve assembly precision.
A roller is respectively installed at the two ends of described lever, and wherein the roller of an end contacts all the time with the edge of cam, and the roller of the other end contacts all the time with the thimble rod movable plate.
On following of the described thimble rod second linear bearing and lower bearing baffle plate are housed; First linear bearing and upper bearing (metal) baffle plate are housed on the thimble rod seat of honour; Thimble rod is installed on first linear bearing and second linear bearing.Strengthen the span between two linear bearings as far as possible, help improving the stability of the axially reciprocating of thimble rod.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the front view of ejector pin mechanism of the present invention.
Fig. 2 is the left view of ejector pin mechanism of the present invention.
Fig. 3 is the cutaway view of lever.
Fig. 4 is the I portion partial enlarged drawing shown in Fig. 1.
Embodiment
Shown in Fig. 1,2,4, ejector pin mechanism of the present invention comprises vacuum cap 1, thimble 2, thimble back of the body cap 3, thimble folder 4, thimble rod 5, back of the body cap 6, the thimble rod seat of honour 7, thimble Connection Block 8, the first linear bearings 9, upper bearing (metal) baffle plate 10, thimble rod movable plate 11, lower bearing baffle plate 12, following 13, the second linear bearing 14 of thimble rod, lever 15, cam 16, back-moving spring 17, lead 18, motor 19, articulation hole bolt 20.
When motor 19 rotations, cam 16 is also along with rotation, because the wobbler action of cam 16 forces roller 156 to drive lever 15 and rotates around lever axis 154.Because roller 151 is assemblied on the lever 15, thus also rotate around lever axis 154, and roller 151 jack-up thimble rod movable plates 11.Along with thimble rod movable plate 11 moves upward, thimble rod 5 drives thimble 2 and does axial linear movement together, moves to the extreme higher position until thimble 2; Back-moving spring 17 is compressed simultaneously.Cam 16 is rotated further, and lead 18 moves down and forces thimble rod movable plate 11 to move downward under the effect of back-moving spring 17, gets back to initial position; Cam 16 rotates under motor 19 drives continuously, can realize that thimble 2 does axial straight reciprocating motion.
