Description

[Detailed Description of the Invention] The present invention relates to the head body of a chemical manipulator, and in particular relates to a novel improvement for moving the workpiece by lowering the base portion of the workpiece vertically and chucking it through a chuck hole. be.

Conventionally used chemical manipulators of this type employ suction cup types, clamping types, etc., but when handling highly dangerous chemicals such as liquids, there is a risk of the chemicals scattering or spilling from the container when chucking. This caused unexpected accidents for workers.

The object of the present invention is to provide extremely effective means for quickly eliminating the above-mentioned drawbacks, and in particular, by providing a chunk hole in a chuck body configured to be movable up and down, The structure is such that one end of the workpiece inserted into the chunk hole is completely chucked or released by a sphere operably provided near the chunk hole.

Hereinafter, preferred embodiments of the chemical manipulator according to the present invention will be described in detail with reference to the drawings.

In the drawings, the reference numeral 1 denotes a base that is integrally molded from aluminum and has a guide hole 2 and a screw hole 5, and a holding portion 4 extending from both ends of the base 1. .5 is provided with a rotary shaft 6 having a threaded portion 6a rotatably via a bearing portion 7.

A rotation driving means 9 consisting of a motor is placed on a holding plate 8 formed on the upper part of the holding part 4, and by rotating this rotation driving means 9, the multi-rotation shaft 6 is rotated.

A longitudinal movable body 10 is screwed onto the threaded portion 6a of the rotating shaft 6, and a chunk body 12 having a chuck plate 11 and a release actuator 15 are disposed at one end of the movable body 10. This release actuator 13 can push down a rotating lever 14 rotatably provided on the chuck body 12. The release actuator 13
A wire 15 connected to is connected to an actuator 17 of an electromagnetic plunger 16 mounted on the base 1.

The chuck body 12 is specifically constructed as shown in FIG. A first holding cylinder 19 coaxially provided on the outer periphery of the holding cylinder 18, a V-shaped blade 20a inside this second holding cylinder 18 ((a guide element 20 biased through the a sphere 22 interposed between the outer periphery and a tapered portion 21 formed at the lower end of the first holding cylinder 19;
A spring 23 is interposed in the first holding cylinder 19, and the first
The holding cylinder 19 is always pressed downward.

Furthermore, a positioning protrusion 2 is provided at one end of the chuck plate 11.
A switch contact rod 25 is provided on the colic of the chuck plate 11 so as to be movable in the axial direction via a spring 26t, and a mounting body 27 is provided on the outer periphery of the second holding cylinder 19. is provided, and in this mounting body 27, an actuator 2 is provided.
A switch 29 having a number 8 is provided corresponding to the switch contact rod 25.

What is indicated by a dashed line in the lower part of FIG. 2 is a workpiece 51 having a container 60 used for analysis, etc., and a holding protrusion 52 and a holding hole 33 are formed in this workpiece 51.

In the above-described configuration, when operating the head body of the chemical manipulator according to the present invention, the base 1 is moved to a desired position via a guide rod (not shown) provided in the guide hole 2, When the rotation drive means 9 is operated, the moving body 10 is lowered by the threaded portion 6a, the holding protrusion 52 of the workpiece 51 is inserted into the chuck hole 17 of the chuck plate 11, and the guide 20 is moved upward and held. The sphere 22 is fitted into the narrow diameter portion 52a of the projection 52, and the positioning projection 24 of the chuck plate 11 is inserted into the holding hole 5 of the workpiece 51.
3 and is positioned, the switch contact rod 25 rises and comes into contact with the switch 29, thereby turning on and confirming chucking.

Furthermore, when releasing the workpiece 51 from the chuck plate 11, when the electromagnetic plunger 16 is fully activated, the release actuator 15 is pushed down in the direction of arrow A via the wire 15, the first holding cylinder 19 is pushed up, and the taper The pressing state of the tapered part 21 of the spherical body 22 by the part 21 is released, the holding protrusion 52 of the workpiece 51 is removed from the chat hole 17, and the release is completed.

Since the head body of the chemical manipulator according to the present invention has the above-described structure and function, chucking of the workpiece is extremely simple and reliable.Since the head body of the chemical manipulator according to the present invention is an insertion type chucking, it is possible to chuck the workpiece in the container at the bottom of the workpiece. It can be moved without spilling all the chemicals.
