For those of ordinary skill, the concrete meaning of above-mentioned term in this application can be understood with concrete condition.
Referring to Fig. 2, Fig. 2 is the structural schematic diagram of bonder swing arm provided by the embodiment of the present application.
The application devises a kind of bonder swing arm, including swing arm main body 4, swing arm support plate 3 and swing arm Bolt plate 2.
Swing arm main body 4 and swing arm support plate 3 are bolted.It should be noted that bolt connection herein can
With are as follows: the bottom of swing arm support plate 3 is embedded with screw rod, and the top of swing arm main body 4 offers threaded hole, the screw rod of swing arm support plate 3
It screws in the threaded hole of swing arm main body 4, realization is bolted.Or: swing arm main body 4 is mounted in swing arm seat, swing arm seat
It is bolted with swing arm support plate 3.The end of swing arm main body 4 is additionally provided with vacuum slot 5 or point plastic pin, for take it is brilliant or
Die bond.
Swing arm Bolt plate 2 is connect with swing arm support plate 3, and specific may be to be bolted.Bonder passes through swing arm spiral shell
Bolt plate 2 is connect with bonder swing arm, drives the movement of bonder swing arm.
The front of swing arm main body 4 offers the first through slot 7 of triangle.Triangle has firm, firm, pressure-resistant spy
Point, so the first through slot 7 for opening up triangle under conditions of guaranteeing the stability of swing arm, more saves material, while letter
Processing technology is changed, with a triangle instead of multiple circular holes.
Bonder swing arm provided by the embodiment of the present application, including swing arm main body, swing arm support plate and swing arm Bolt plate；Pendulum
Arm body is bolted with swing arm support plate；Swing arm Bolt plate is connect with swing arm support plate；The front of swing arm main body opens up
There is the first through slot of triangle.Bonder swing arm provided herein is by substituting traditional circle with the first through slot of triangle
Hole also simplifies processing technology, will not influence the normal work of swing arm under the premise of realizing mitigation total quality, solves
The problem of existing round swing arm lightening hole can reduce the stability of bonder swing arm.
Further, the second through slot 6 of triangle is opened up in the two sides of swing arm main body 4.With the effect class of the first through slot 7
Seemingly, processing technology is simplified while saving material.In addition, taking during the swing arm of high-frequency high-speed swings and up and down
During brilliant, die bond, relative to multiple circular troughs, front face area reduces the second through slot 6 of triangle, so that resistance reduces, makes
Positioning accuracy and production efficiency improve.
If swing arm can generate biggish deformation, in the case where swing arm longer (being greater than 15cm) in order to improve swing arm main body 4
The reinforcing rib 9 of " X " type can be arranged in the inside of the first through slot 7 in rigidity.The gap that reinforcing rib 9 is constituted with swing arm main body 4 is also
Triangle, so that the structure of entire swing arm has more stability.
It cracks in order to avoid stress collection neutralizes, chamfering 8 can be carried out in the infall of the reinforcing rib of " X " type and processed.In addition,
There is also angles for the triangle that swing arm main body 4 itself, swing arm main body and reinforcing rib 9 are constituted, it is therefore preferable that these angles all into
Row chamfer machining.
Pressure-regulating device 1 can be set on swing arm Bolt plate 2, for adjusting and the compression journey of swing arm end and chip
Degree.Specifically, pressure-regulating device 1 includes the spring being sleeved on bolt and the nut being locked on bolt；One end of spring
It is contacted with swing arm Bolt plate, the other end is contacted with the installation part of bonder.
Further, as shown in Figure 1, traditional swing arm Bolt plate 2 is relatively thin.It is found by the emulation of ABAQUS, changes spiral shell
The thickness of keyhole supporting zone can significantly improve the intrinsic frequency of bonder swing arm, so as to so that the intrinsic frequency of die bond low order
Rate improves the patch precision of complete machine far from the external environments excited frequency such as linear motor.Thickness is directly proportional to intrinsic frequency, because
This, the thickness of swing arm Bolt plate 2 provided by the embodiment of the present application increases the half for 4 thickness of swing arm main body.
Specifically, swing arm main body 4, swing arm support plate 3 provided by the embodiment of the present application and swing arm Bolt plate 2 are by carbon fiber
Dimension enhancing based composites are made, because fibre reinforced based composites density is low, specific strength with higher, than rigidity.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the application, rather than its limitations；To the greatest extent
Pipe is described in detail the application referring to foregoing embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, each embodiment technology of the application that it does not separate the essence of the corresponding technical solution
The range of scheme.
