Abstract

PURPOSE:To average the resistance value of a coil by measuring the resistance value of the coil after it is wound and feeding the measured result of this resistance value back to the coil winding stage to control the winding number of the coil. CONSTITUTION:The resistance value, the winding amount, other reference data which are the reference of the winding amount of the coil are inputted in a reference data inputting part 2. The inputted data are sent to a controller 4 of winding number through a data processing part 3 to determine the winding amount of the coil. On one hand, a coil winding machine 5 winds a fixed amount of wire to a magnetic core in accordance with the data of winding amount from the controller 4 of winding number to wind up the coil 1. Resistance values of the wound up coil 1 are measured by a resistance measuring instrument 6 in sequence and the resistance data obtained here are inputted into the data processing part 3 again. At the same time, they are operated in comparison with the inputted reference data in the reference data inputting part 2 and the average of the resistance is corrected and outputted as the data of the winding amount of the next coil. Consequently, it is possible to obtain a coil small in the variation of resistance values.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a winding machine for a watch coil.

[Summary of the invention]

The present invention measures the average resistance value of the coil after winding in the coil winding process of a watch coil, and feeds back information of the measurement result to the coil winding process to keep the coil resistance value constant during winding. The purpose is to maintain the

[Conventional technology]

FIG. 2 is a block diagram showing a conventional coil winding process. In the coil winding process of winding a watch coil, data for winding 1 is input in advance to the reference data input section 2, and this data is sent to the winding control device 4. Based on the input C1, the coil winding machine 5 winds a certain amount of wire around the magnetic core to complete the coil l. The coil resistance of the completed coil was measured in a subsequent inspection process.

[Problem to be solved by the invention]

However, since the wire of the watch coil has a slightly different wire diameter depending on the end and end, there is a problem in that even if the wire is wound with the same number of turns, the resistance value varies from coil to coil. Therefore, in the next inspection process, the resistance value of the coil is measured, and if the measured resistance value of the coil is outside the standard, the amount of winding of the coil is changed for each loft of the wire so that the resistance value is within the standard. They were forced to perform inefficient work.

[Means to solve the problem]

The present invention has been made to solve the above problems, and in the coil winding process, the coil resistance value of the winding method is sequentially measured online, and the measurement results are fed back to the winding machine. The amount of winding of the coil is determined, and as a result, a coil with a constant resistance value is obtained.

[Effect]

According to the configuration of the present invention, a coil that maintains a constant resistance value can be wound without being influenced by the wire diameter of the wire rod that is the material of the coil.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram illustrating the concept of the present invention. In the drawing, 2 is a reference data input section, 1 is a coil, and 3 is a reference data input section.
is a data processing unit, 4 is a winding number control device, 5 is a coil winding machine,
6 is a coil resistance measuring device. The coil resistance value, the winding amount, and other reference data, which serve as a reference for the winding amount of the coil, are entered manually in the reference data input section 2. The reference data manually entered here is sent to the turns number control device 4 via the data processing section 3, and the eI of the coil is determined. On the other hand, the coil 1 I15 winds the coil I by winding a certain amount of wire around the magnetic core based on the winding amount data from the winding number control device 4. The resistance value of the coil l wound in this manner is sequentially measured by the resistance measuring device 6, and the resistance value data obtained here is inputted again to the data processing section 3 and also to the reference data section 2. A comparison calculation is made with the input reference data, and the average value of the resistance is corrected and output as the winding amount data for the next coil. The winding amount data corrected and outputted here is inputted again to the winding number control device 4, and the coil winding machine 5 winds the next coil 1 with the winding amount based on this corrected data. Thereafter, this operation is repeated, and a coil with little variation in resistance value can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, by sequentially feeding back the coil resistance value data after winding to the winding process, the resistance value of the coil to be wound is averaged, and as a result, the resistance value variation is extremely small. Coils can be provided.
