Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a work holding jig for fine manual work, and more particularly to a rotation mechanism capable of regulating the work posture of a multi-head index head.

(To) Technical Background In many cases, fine manual work in the mass-produced electronic component manufacturing process is performed by holding the workpiece in an appropriate posture with a holding jig, and there is a trend to multi-head the jig in order to improve work efficiency. I came. Furthermore, it has been difficult to provide a simple and highly reliable workpiece posture regulating means for uniformly regulating the posture of a workpiece accompanying the index motion of a multi-head.

(Q) Prior art and problems The internal rotation position control method of the workpiece posture regulating means is usually performed using a satellite rotation mechanism, but the positioning mechanism is often complicated and many general-purpose multi-head jigs are used in transfer jig lines and the like. In this case, the disadvantage was that the jig costs were high.

←) Purpose of the Invention The object of the present invention is to provide a simple and highly reliable rotation mechanism for commonly regulating workpieces in a multi-head holding jig.

(e) Structure of the Invention The present invention is characterized in that a work holding jig for chucking at least two works and circulating them in the order of processes is provided with a stage.

(f) Embodiments of the Invention Preferred embodiments of the invention will now be described in detail with reference to the drawings.

FIG. 1 is a plan view of a two-stop holding jig rotation mechanism according to an embodiment of the present invention, and FIG. 2 is a partially sectional side view, in which 1 is a chucking head, and 2 is a child rotating table. ,
8 is a tiltable board (child figure translocation), number is the main rotating table, 5 is a stand (11! rotating seat), 6 is a pallet, 7 is a steel ball, 8
indicates a compression spring, and W indicates a workpiece.

In the figure, a parent rotary table 4 is mounted on a parent rotary seat on the upper surface of a stand 5 disposed on a transport pallet 6, and is rotatable about a stud pin 51. and,
The substrate 8 is configured to be tiltable by a hinge fulcrum 41 provided on a concentric circle near the center of rotation, and is rotated to a position where the concentric circle is equally divided into two with respect to the outer rotation center of the substrate. Place the center stud pin 31 on the planter rotating table 8.
It forms the seat of the. The chucking head 1 is disposed on a plurality of child rotary tables 2 placed on a seat, and the work W is held in a predetermined posture by the vice mechanism 11 of the head. In the multi-head holding jig with such a configuration, the plurality of workpieces gripped are transferred to the main rotary table 4.
It becomes possible to transport the workpiece W to a predetermined work position by the arbitrary revolution of the child rotary table 2 and the arbitrary rotation of the child rotary table 2.Next, we will ask about the posture control mechanism for the workpiece W gripped by the chucking head l. The sliding surface between the front 1i3 rotary table number and the main figure transfer seat 6, and the child turntable 2 and the child figure transfer table 8
The rotary table 4
．． On the side of 2, there are 4 holes 48.21 into which the copper ball 7 sinks by a predetermined amount.
Steel ball indexing holes 51 and 82 each containing a compression spring 8 for pressing the S ball 7 are provided in the rotation seats 6 and 8 to constitute a rotation positioning mechanism. In such a configuration, the positioning of the index motion of the chucking head is performed by pressing the steel ball into the notch hole 4F3, and the posture control of the workpiece of the positioned head is performed by the notch hole 21 of the child figure translocation and the child workpiece. This can be done easily by selecting the steel ball indexing hole 82 of the figure translocation.

(2) Detailed Description of the Invention As described above, the rotation mechanism of the multi-head holding jig according to the present invention has a simple structure, so it can provide a workpiece gripping posture control structure that is inexpensive, highly reliable, and has good workability.
