Description

[Detailed description of the invention] This invention relates to a spring hanging device compatible with automatic machines that can easily attach even relatively small springs to current automatic assembly machines that cannot perform complicated operations, is difficult to dislodge, and satisfies safety standards. .

FIG. 1a is a plan view of a conventional spring in use, and FIG. 1b is a front view thereof. In both Figure 1a and Figure 1b, 1 is an iron plate called a sub-panel with resin outsert, and 2
is a lock plate made of a resin component having a bearing that fits the axis of the sub-panel 1. The lock plate 2 has a hook portion 2a formed with a notch near its tip, and the sub-panel 1 also has hook portions 1a at predetermined locations. A coil spring 3 having a tensile force is attached between both hook portions 1a and 2a.

This coil spring 3 is first attached to the hook portion 2a of the lock plate 2 by hand.
After the coil spring 3 is attached to the hook portion 1a of the sub-plate 1, the other end of the coil spring 3 is attached to the hook portion 1a of the sub-plate 1.

In the structure of such a conventional spring hanging device, the coil spring 3 can be attached in multiple directions and the operation is complicated, making it nearly impossible to use an automatic assembly machine to perform the work. .

Furthermore, even if it could be installed, it would require an extremely expensive item. Therefore, it was not possible to use automatic machines.

This idea was made to eliminate the above-mentioned drawbacks of the conventional method, and by making it possible to install the spring simply from the top, bottom, left, right, front, and back, we created a spring hanging device that can be automated and is compatible with automatic machines. The purpose is to provide.

Hereinafter, an embodiment of the spring hanging device of this invention that is compatible with automatic machines will be described based on the drawings. FIG. 2a is a side view showing the configuration of one embodiment, and FIG. 2b is a front view thereof.

In both FIGS. 2a and 2b, reference numeral 5 denotes a lock plate, and the lock plate 5 has a bearing 5a that fits on the shaft 4a of the sub-panel 4.
A spring hanging portion 5b is formed at the upper end of the lock plate 5.

Further, spring hanging portions 4b are also formed at predetermined locations on the sub-plate 4. Since both spring hanging parts 4b and 5b have the same shape and opposite directions, the spring hanging part 5b will be described as a representative.

As is clear from FIG. 2a, the spring hanging portion 5b has one end formed in a semicircular shape, and the other end formed integrally with the front of the lock plate 5, as shown in FIG. Enlarged view of circle A in figure a)
As shown, it has a straight part 5c, a recessed part 5d, and a convex part 5e.

The relationship between the concave portion 5d and the convex portion 5e is such that they have a predetermined width in the longitudinal direction of the center portion of the spring hanging portion 5b, as shown in FIG. , a semicircular groove-like recess 5d is formed, and by forming this recess 5d, a semicircular protrusion 5 is formed on the opposite side of the spring hanging part 5b.
e is formed. Therefore, the spring hanging portion 5b is formed into a plate shape having a concave portion 5d and a convex portion 5e.

The spring hanging portion 4b of the sub-panel 4 is also labeled with the same reference numeral as the spring hanging portion 5b, with 4d representing a recess and 4e representing a convex portion. However, as is clear from FIG. 2b, the convex portion 4e faces the convex portion 5e of the spring hanging portion 5b.

By forming the spring hanging portions 5b, 4b in this way, it is possible to attach by operating only from above and below, and the third
As is clear from Figure b, the robot is trying to escape from the pink color.

Also, when viewed from the side, it has a semicircular shape, as is clear from Figure 3a, so that the spring 6 can be easily inserted from the top, and the head, that is, Figure 3a.
The size of the right end is slightly larger than the inner diameter of the spring 6.

Next, the operation of the spring hanging device for automatic machines constructed as described above will be explained.

The spring 6 is hung between the spring hanging parts 4b and 5b. First, as shown in FIG. 4, the spring 6 is brought to the spring hanging parts 4b and 5b using the pin 7 of the robot. Then, at each recess 4d, 5d, a third
When it comes to the position shown in Figure b, the pin 7 of the robot stops.

Here, as shown in FIG. 4 and FIG. 3c,
This time, the pin 8 of the robot comes down and presses the side of the spring 6. This causes the spring 6 to deform. Utilizing this, as is clear from FIG. 3a, both ends of the spring 6 pass from the semicircular ends of the spring hanging parts 4b and 5b through the straight part 5c (the same goes for the spring hanging parts).
It is pushed into the stepped portion 5f (FIG. 3a), and both ends of the spring 6 are locked there.

Once both ends of the spring 6 are locked to the stepped portion 5f, even if an attempt is made to remove the spring 6, both ends of the spring 6 are caught by the stepped portion 5f, and the spring 6 cannot be removed.

The straight portions 5c (4c not shown) are provided on the spring hanging portions 4b and 5b, respectively, in order to prevent the spring 6 from coming off due to rotation. This is to make the diameter of the pin 8 of the small robot as large as possible (to ensure the strength of the pin).

In this way, in this invention, the spring 6 is attached to the spring hanging parts 4b, 5b by utilizing the deformation of the spring 6, so that the spring 6 is once attached to the spring hanging parts 4b, 5b.
It has a structure that prevents it from coming out once it is inserted into the
It can also comply with safety standards (UL).

As described above, according to the spring hanging device compatible with automatic machines of this invention, the spring hanging parts on the sub-panel and the lock plate are plate-shaped with semicircular tips, have a recess on one side, and have a recess on the other side. Since the surface has a convex part so that it can be installed from either the top or bottom, left or right, or front or back, the spring can be installed easily and automatic machines can be used, reducing man-hours and work. This makes it possible to reduce the number of employees.
