Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention provides a loop-shaped material having a loop shape and having parallel leads at both ends, which is carried out from a conveyance path in which the vehicle is conveyed on horseback. The present invention relates to a positioning and feeding device for loop-shaped parts, which positions the parts and then supplies them to an automatic insertion machine.

(Prior art) For example, the work of inserting electronic components such as resistors, capacitors, and diodes into a printed circuit board, or inserting the leads of the electronic components into a printed circuit board and then bending them to mount them. ,
Most of it is automated. That is, electronic components supplied from a parts feeder or the like are chucked by a chuck of an automatic insertion machine, and then directly transferred to a printed circuit board, and the leads of the electronic components are inserted into the printed circuit board. Incidentally, even if the above-mentioned electronic components such as resistors and capacitors have different characteristics (resistance R, capacitor capacitance C), the pitch of the leads to be inserted is the same, so that they can be chucked and inserted using the same chuck. Therefore, the automatic insertion machine can be shared, and the process can be easily carried out both in terms of cost and technology.

However, as shown in Figure 6 A and B, coil a has a loop shape, and parallel leads b and
Examples of the loop-shaped component A having the shape b include loop-shaped electronic components such as a loop coil and a loading coil, and the characteristics of such a loop-shaped component are determined by the external dimensions. Therefore, there were problems that made it difficult to automate, such as the pitch of leads b and b being different depending on the characteristic values. Also,
Although it is possible to feed the specially shaped loop-shaped part A as described above to a predetermined position by a bar feeder, it is difficult to transport the loop-shaped part A in an aligned state. Moreover, it is almost impossible to supply the loop-shaped part A to the chuck mechanism of an automatic insertion machine in a positioned state.

(Problems to be Solved by the Invention) As mentioned above, in the conventional technology, it is not possible to chuck the loop-shaped component A in an aligned state and insert it into a printed circuit board, etc. In the case of A, the insertion into the printed circuit board is performed manually by an operator. As a result, workability was poor and the quality of the products varied.

This invention was made in view of the above-mentioned circumstances, and its purpose is to automatically position and feed loop-shaped parts carried out from a conveyance path to an automatic insertion machine. Another object of the present invention is to provide a feeding device for positioning a loop-shaped component, which can improve workability.

[Structure of the invention]

A drive mechanism that drives a pair of movable arms of the chuck parallel to the opening/closing direction to chuck the loop-shaped component from both sides, and a drive mechanism that supports the chuck and supplies the loop-shaped component chucked to the chuck to the automatic insertion machine. It is characterized by comprising an insertion mechanism. The loop-shaped component is generally called a loop coil, and its characteristics are determined by its external dimensions, so if the shape changes before it is inserted into a printed circuit board, etc., the characteristic values will change. . Therefore, the deformation must be kept extremely small, and the structure is such that this requirement can be fully satisfied.
