The utility model provides a stable in structure is reliable, adaptation high -frequency work, long service life's gu thimble device of brilliant machine.
Description
Technical field
The utility model relates to the thimble device of a kind of bonder.
Background technology
Die bond is the important operation of LED, and owing to affecting by factors such as human costs, the application of automatic bonder is more and more extensive. Thimble device is then device essential in automatic bonder. It mainly plays and ejects wafer, makes wafer from the effect of separation brilliant film. Owing to wafer is very little and fragile, add that bonder speed goes is fast, the position precision of thimble device and the requirement of response speed is more and more higher. Existing bonder thimble device all adopts cam follower structure as shown in Figure 2. 701 is thimble, and 702 is linear bearings, and thimble 701 is vertically moved, and 703 is the output revolving shaft of drive-motor. It is especially by the height of the Bit andits control thimble 701 of cam 704 and relies on spring 705 that thimble is resetted. Based on the feature of automatic bonder, for ensureing the handiness of motion, the bigger spring of back stretch 705 cannot be set, thus, above-mentioned cam follower structure easily occurs the situation that thimble 701 departs from cam 704 overshoot in high-speed motion, thus cause thimble 701 highly uncontrolled, make thimble 701 cross quick-wearing or cause damage to wafers. Therefore, prior art needs to improve.
Practical novel content
In order to overcome the deficiencies in the prior art, the utility model provides the thimble device of a kind of bonder, and Stability Analysis of Structures is reliable, adapts to high-frequency work, it may also be useful to the life-span is long.
The utility model solves the technical scheme that its technical problem adopts:
The thimble device of a kind of bonder, comprise the transmission rig of drive-motor, thimble and connecting ejector pin and drive-motor, described transmission rig comprises rhombus four-bar mechanism and horizontally disposed screw mandrel, described screw mandrel be connected to drive-motor output shaft and by drive-motor driven rotary, described rhombus four-bar mechanism both sides are respectively provided with a thread slider being sleeved on described screw mandrel and mate with screw mandrel, and the screw thread direction of described two thread sliders is contrary.
As the improvement of technique scheme, the lower end of described thimble is connected with connecting rod, and the lower end of described connecting rod is connected to rhombus four-bar mechanism, and described connecting rod is set with linear bearings.
As the further improvement of technique scheme, described drive-motor adopts servomotor.
Further, described drive-motor is connected with reduction box, and described screw mandrel is connected to the output terminal of described reduction box.
Further, the screw thread in described thread slider scribbles lubricating grease.
The beneficial effects of the utility model are: drive-motor drives screw mandrel to rotate, screw mandrel rotarily drives two thread sliders and moves along screw mandrel, owing to the screw thread direction of two thread sliders is contrary, both travel directions are also contrary, and both move inward simultaneously thus drive rhombus four-bar mechanism to narrow and promote shifting on thimble; Contrary, drive-motor reverse rotation, then two thread sliders can be made simultaneously outwards mobile thus drive rhombus four-bar mechanism become wide promote thimble under move, the thread slider adopting two screw thread directions contrary, the Deformation velocity of rhombus four-bar mechanism can be made faster, adapt to the high frequency motion of bonder.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing thimble device.
Embodiment
With reference to Fig. 1, the thimble device of a kind of bonder, comprise the transmission rig 3 of drive-motor 1, thimble 2 and connecting ejector pin 2 and drive-motor 1, described transmission rig 3 comprises rhombus four-bar mechanism 301 and horizontally disposed screw mandrel 302, described screw mandrel 302 be connected to drive-motor 1 output shaft and by drive-motor 1 driven rotary, described rhombus four-bar mechanism 301 both sides are respectively provided with a thread slider being sleeved on described screw mandrel 302 and mate with screw mandrel 302, and the screw thread direction of described two thread sliders is contrary. Adopt said structure, the screw mandrel 302 gone by drive-motor 1 is rotated, under the effect of screw thread, two thread sliders move along screw mandrel 302, owing to the screw thread direction of two thread sliders is contrary, both are mobile is also oppositely contrary, i.e. inwardly (close to each other) or outwards (mutually away from) motion simultaneously simultaneously, two thread sliders simultaneously inward promote rhombus four-bar mechanism 301 to narrow thus promote and thimble 2 moves; Contrary, the while of two thread sliders, outwards movement progress rhombus four-bar mechanism 301 becomes wide thus promotes thimble to move for 2 times, shifting, lower shifting on thimble 2 can be realized by turning to of varying cyclically drive-motor 1, complete the action ejecting wafer, the thread slider adopting two screw thread directions contrary, the Deformation velocity of rhombus four-bar mechanism 301 can be made faster, and thimble 2 ejects and resets faster, adapts to the high frequency motion of bonder.
In order to improve the stability that thimble 2 moves up and down, ensure thimble 2 vertical motion, in the present embodiment, it is preferable that, described thimble 2 times ends are connected with connecting rod 4, and described connecting rod 4 times ends are connected to rhombus four-bar mechanism 301, and described connecting rod 4 is set with linear bearings 5.
In order to precisely control in the present embodiment, it is preferable that, described drive-motor 1 adopts servomotor.
In the present embodiment, it is preferable that, described drive-motor 1 is connected with reduction box 6, and described screw mandrel 302 is connected to the output terminal of described reduction box 6.
In order to improve stability, the reliability of transmission, it is to increase work-ing life, in the present embodiment, it is preferable that, the screw thread in described thread slider scribbles lubricating grease.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
