Description

[Detailed explanation of the invention] This invention is suitable for electronic parts such as motor coils for watches,
Related to assembly jigs for small parts and alignment plates that also serve as transportation and storage.

Conventionally, in production lines for electronic components such as motor coils for watches, jigs suitable for use throughout the entire process have not been provided, and electronic components have to be individually set on processing machines in each process. Even when processing this or a large number of them at the same time, it was necessary to rearrange them many times in a jig that is used only for that process. Therefore, work efficiency is extremely low, and it is a major obstacle to automation of production lines. This idea was made in consideration of these points, and provides an alignment plate that functions as an assembly jig, as well as its transportation and storage, in the production line of electronic components and small parts such as motor coils for watches. In particular, the work area is on the opposite side of the alignment plate from the clamp part, and is intended to greatly promote the automation of production lines for electronic components and small parts that require three-dimensional space.

Hereinafter, an embodiment in which this invention is applied to a motor coil for a watch will be described in detail with reference to the drawings.

Fig. 1 shows the entire alignment plate according to this invention, and Fig. 2 is a partially enlarged view of the alignment plate. It is roughly divided into a clamp spring 2 for fixing the component C, a clamp spring holding plate 3, and a screw 4 for setting these together.

The main body plate 1 engages with the positioning pin 1a of the motor coil that is aligned and fixed here, the conveyor pin that applies the feed, a hole 5 that engages with the positioning pin of the main body plate, and a spring displacement when operating the clamp spring 2. It is formed from a through window section 6 for. The assembly part C shown in FIG. 2 is called a motor coil magnetic core.

Next, the clamp spring 2 is made of a plurality of continuous thin plate members having the same shape, and each claw part 2a is connected to the main body plate protrusion 1a at an equal distance via the spring presser plate 3, and a screw 4 is attached to the clamp spring 2. It is fixed to the main body play 1 by. At that time, the protrusion 1a of the main body plate 1 and the claw part 2a of the clamp spring 2 are connected as shown in FIG.
The distance y is fixed to be smaller than the distance x corresponding to that of the component C to be clamped.

The spring holding plate 3 includes a hole 3a into which the actuating piece 7 is inserted when pressing the clamp spring 2 back, and a hole located at the same position as the hole 5 for conveying and positioning the main body plate 1, and having a slightly larger diameter than that hole. It is formed so as not to interfere with the positioning of the main body plate 1. This spring holding plate 3
This prevents the claw portion 2a from floating upward when the clamp spring 2 is pushed back, and provides constraints so that the force of the clamp spring acts effectively.

Next, the operation when setting the motor coil C on the alignment plate 1 will be explained.

The actuating piece 7 is lowered, the clamp spring 2 is pressed and displaced downward, and the tip claw portion 2a retreats in proportion to the displacement, causing the claw portion 2a and the pin 1a of the main body plate to move back.
The distance y from the motor coil C becomes larger than the corresponding dimension of the motor coil C. In this state, the motor coil is engaged with the pin 1a automatically or in a posture regulated to some extent by a manual (the diameter of the pin and the diameter of the hole in the motor coil may be loose), and then the actuating piece 7 is moved upward. When the clamp spring 2 is returned to its original state, the claw portion 2a of the clamp spring 2
contacts the end face of the motor coil and exerts a force that presses it against the pin 1a. The force at that time increases in proportion to x-y in FIG. Note that the shape of the claw portion 2a does not necessarily have to be the same as the motor coil;
The pin 1a may have any shape as long as it can regulate the angle at which the motor coil is set, or the pin 1a does not necessarily have the shape shown in the drawings, but may have a protruding shape that resists the acting force of the clamp spring.

As is clear from the above description, the alignment plate for small parts such as electronic components according to the present invention includes a main body plate in which a large number of through windows or recesses are aligned in the longitudinal direction, a clamp spring, and a spring. The body plate is composed of a holding plate, and the body plate has protrusions such as pins on the side opposite to the action of the clamping spring to restrict the planar movement of the item to be clamped, and a projection to enable displacement of the clamping spring. The clamping spring has a through window or a recess and a hole for conveyance and positioning, and the clamping spring is located between the main body plate and the spring holding plate and has a claw part for holding down small parts such as electronic parts. It has a hole for pressing and displacing the clamping spring from above when clamping and unclamping, and when the clamping spring part is pressed from the spring holding plate side, the claw part moves backward and the main body plate Since the clamp for small parts such as electronic parts fixed between the protrusion and the claw part is released, a large number of small parts such as electronic parts can be aligned and fixed with a simple operation. Therefore, in the production line, it can be used consistently throughout the entire process as an assembly jig and an alignment plate for transportation and storage, greatly improving production efficiency and
This makes it possible to automate the process, and since the surface of the part is open even when it is clamped, it has the effect that processing on the surface can be easily performed without any hindrance.
