Abstract

The present invention provided a joining device which controls a pressurizing force easily, surely, finely and also automatically. The device is equipped with a driving means 41 for driving a movable electrode transfer means 40, an operating means 43 for transmitting a signal for instructing the operation of the driving means 41, and a controller 42. The controller 42, on the basis of the signal transmitted from a sensor 15 for detecting a set pressurizing force and from the operating means 43, controls the operation of the driving means 41 for driving the movable electrode transfer means 40, in a manner enabling a movable electrode 12 to stop at each of the retreat position the joining position and the temporary stop position set before the joining position on a path going from the retreat position to the joining position. The controller 42 also has the ability to automatically change at least the joining position of the movable electrode 12, on the basis of a detection signal from the sensor 15 for detecting a set pressurizing force.

Description

technical field [0001] The present invention relates to a jointing device capable of achieving proper jointing of jointed parts in a pressurized state. Background technique [0002] Joining devices are known which enable joining of the parts to be joined in a pressurized state. Such joining devices include resistance welding devices used for spot welding (spot welding) and seam welding (seam welding), etc., reflow soldering devices, and the like. [0003] The above-mentioned resistance welding device is used for parts of small electronic appliances, specifically, between parts representing parts of small electronic appliances, such as in small assembled batteries, using wires with a thickness of 20 μm to connect a plurality of batteries to each other. The joining between electrodes of the same pole, the joining of small motor coils, etc., are used in the superimposition or butt joint of parts composed of joint metals. A single or multiple movable electrodes apply a specifie...

AI Technical Summary

Problems solved by technology

As a result, there are problems that the pressing force applied to each part is not uniform and the joining quality of the parts is uneven due to the proficiency of the operator, individual differences among operators, etc.

[0019] In addition, even in the soldering device as the bonding device, in order to control the bottom dead center position of the pressurizing head provided with the electrode heating head, it is necessary to adjust the position of the brake for controlling the stepping position of the pedal. This device has Same problem as resistance welding device 1
