Motor manufacturing line and its control method

Abstract

A motor production line (1) which produces at least stators. It comprises a press device (10) which applies press working a plurality of times to a long-sized steel plate while conveying the latter, so as to form a stator core (80), and a stator assembling device (4) for assembling stators. Installed between the stator assembling device (4) and the press device (10) is a stator core transfer device (22) capable of successively transferring stator cores (80) formed in the press device (10) directly to the stator assembling device (4). It is preferable to install a rotor assembling device (3) for assembling rotors and a rotor core transfer device (21) capable of successively transferring rotor cores (70) formed in the press device (10) directly to the rotor assembling device (3).

Description

technical field [0001] The invention relates to a production line suitable for manufacturing motors with a small amount and many varieties and a control method thereof. Background technique [0002] When manufacturing a motor, the rotor and the stator that constitute the motor are manufactured separately, and finally these parts are combined to form a single motor. In addition, both the rotor and the stator use a rotor core and a stator core formed by laminating a plurality of electromagnetic steel sheets punched into a predetermined shape as iron cores. These rotor cores and stator cores are formed by a press device that performs a plurality of press processes while conveying a long electrical steel sheet. [0003] Such as Figure 9 As shown, in the conventional motor manufacturing line 9, in order to improve the production efficiency of rotor cores and stator cores, a dedicated stamping factory 91 equipped with a large stamping device can be used for mass production. The...

Problems solved by technology

[0009] However, when producing a variety of motors in small quantities, the number and types of rotor cores and stator cores in stock will inevitably expand if the above-mentioned conventional motor manufacturing line is used, and the storage space required for the inventory warehouse will increase in size.

In addition, the storage time of the rotor core and the stator core is prolonged, and the deterioration of the quality characteristics such as the deterioration of the insulation characteristics due to rust, foreign matter, etc.

[0010] In addition, as the storage time in the inventory warehouse increases, the chances of changing the placement, changing the costume, etc. also increase, and the possibility of causing bad deformation will also increase.

In addition, as measures to suppress the above-mentioned deterioration of quality, for example, antirust treatment, storage in a storage box, etc. are required, and there is also an increase in manufacturing costs due to management costs caused by this.

[0011] Also, as mentioned above, since the storage time of the rotor core and the stator core increases, the delivery time from the start of production to the completion is very long, causing various disadvantages
