Description

Description: TECHNICAL FIELD The present invention relates to a wire end treatment device for ultrasonically welding a metal wire rod to a metal partner to be welded and then integrally molding with a resin. .

[Prior Art] Metal wire (including stranded wire), solid rod, flat bar, etc.
The terminal treatment of connecting the welding target metal body such as another metal filament or metal molded product to the tip of the metal filament consisting of a pipe or the like and resin-molding the metal filament and the welding partner metal Place both body and body on an anvil type jig, transmit ultrasonic vibration from ultrasonic horn of ultrasonic welding machine to both, rub the contact surface of both by ultrasonic vibration to destroy the oxide film, Both surfaces were smoothed and welded by plastic deformation, and then the periphery of the welded portion was molded with resin for protection and reinforcement.

[Problems to be Solved by the Invention] However, conventionally, after ultrasonic welding of a metal filament and a welding partner metal body, an operator attaches an already welded body of the metal filament and the welding partner metal body to the anvil. There was a problem that it had to be removed from the mold jig and transferred to the molding machine.

Further, when the types and sizes of the metal filaments are different, there is a problem that it is necessary to transfer the metal filaments to an ultrasonic welding machine separately installed so as to accommodate them.

This transfer operation is necessary because the ultrasonic horn and the anvil type jig used for ultrasonic welding must be changed every time the type and size of the metal filament and the metal partner to be welded are different.

Further, the transfer of the already welded body into the mold of the molding machine needs to be performed accurately so as not to damage the mold due to the displacement of the transferred already welded body. It is extremely careful to transfer the welded metal body without applying a tensile force or peeling force due to breakage or peeling to the welded part. Since it is heated above, there is a serious mental and physical burden on the worker, it is not suitable for continuous work, work efficiency is extremely poor, and there are problems that quality is stable and control is not preferable.

Furthermore, there is a possibility that defective products detected during and after welding may flow out to the next step in the transfer operation.

An object of the present invention is to provide a striatal terminal processing device that can perform terminal processing in an automated manner.

[Means for Solving the Problems] To explain the configuration of the present invention for achieving the above object, a wire striation terminal treatment device according to the present invention comprises a metal striation to be welded and a welding partner metal body. A transportable anvil type jig for overlapping and supporting the parts to be welded,
A transport mechanism for transporting the anvil-type jig, and at least one ultrasonic welding machine installed adjacent to a transport path of the transport mechanism for welding the metal linear body and the welding partner metal body, A molding machine for integrally molding the welded metal filament and the welding partner metal body with a resin, and a transfer for transferring the welded metal filament body and the welding partner metal body to the molding machine. And a mounting mechanism.

[Operation] By using the transfer mechanism, the anvil jig can be automatically transferred to the ultrasonic welding machine. By using the transfer mechanism, transfer from the ultrasonic welding machine to the molding machine can be performed automatically. Therefore, terminal processing can be automatically performed.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 5.

In this embodiment, as shown in FIG. 2, the welding partner metal body 2 insulated and supported by the insulating support body 1 is set on a portable anvil type jig 3 as shown in FIG. An example is shown in which the tip of the metal filament 4 is superposed on each of the welding counterpart metal bodies 2 on the jig 3 and ultrasonically welded.

The linear body terminal processing apparatus of the present embodiment is a belt conveyor type transport mechanism 5 for transporting a portable anvil type jig 3 in which a metal linear body 4 and a welding partner metal body 2 are set to a welding point.
Have. The transport mechanism 5 is accompanied by an anvil jig positioning mechanism 6 for fixing the anvil jig 3 at a predetermined position of the transport mechanism 5. Ultrasonic welding machines 7 and 8 are installed along the carrying direction of the carrying mechanism 5. In this way, multiple ultrasonic welding machines 7 and 8 are installed because the ultrasonic horns 7A and 8A and the anvil type curing machine are used in accordance with the welding points at multiple locations, the type and size of the metal filaments. This is because it is necessary to change the setting of the tool 3. 7B and 8B are positioning jigs for the ultrasonic welding machines 7 and 8. A molding machine 9 having a molding die 9A is installed at the end of the transport mechanism 5. Between the terminal ultrasonic welding machine 8 and the molding machine 9, the welded metal filament body 4 and the welding partner metal body 2 are removed from the anvil type jig 3 and transferred to the molding die 9. A transfer mechanism 10 is installed. The transfer mechanism 10 has a clamp means 10C having an insulating support body clamp tool 10A for clamping the insulating support body 1 and a metal linear body clamp tool 10B for clamping the metal linear body 4.

Next, the operation of such a striatal terminal processing device will be described. As shown in FIG. 4, the anvil type jig 3 in which the metal filaments 4 are superposed on the metal body 2 to be welded is positioned and fixed on the transport mechanism 5 by the positioning mechanism 6, and the welding position of the ultrasonic welding machine 7 is set. Transport to. At the welding position, the ultrasonic wire horn 7A of the ultrasonic welding machine 7 ultrasonically welds the metal filament 4 to the metal body 2 to be welded. When there are a plurality of welding points, the anvil jig 3 is moved to the welding position of the next ultrasonic welding machine 8 and the transport mechanism 5 is moved.
And carry out ultrasonic welding. Alternatively, when the types and sizes of the metal filaments 4 are different, the anvil jig 3 is not stopped at the position of the ultrasonic welding machine 7, but is directly transferred to the welding position of the ultrasonic welding machine 8 by the transfer mechanism 5. Ultrasonic welding. When it is necessary to perform such various types of ultrasonic welding, it is necessary to install a corresponding number of ultrasonic welding machines along the transport direction of the transport mechanism 5. The anvil-type jig 3 on which the already welded body composed of the metal filaments 4 that have been welded and the metal body 2 to be welded is placed is transported by the transport mechanism 5 to the position of the transfer mechanism 10. In the transfer mechanism 10, the welded metal body is welded so as not to apply a tensile force, a peeling force, or the like resulting from breakage, peeling, or the like to the welded portion of the metal body, and the shape is maintained without tension. Meanwhile, the metal filament 4 and the insulating support 1 are clamped by the metal filament clamp 10B and the insulating support clamp 10A and transferred to the molding die 9A of the molding machine 9. Molding machine 9
Then, the already-welded metal filament 4 and the welding partner metal body 2 which are positioned and set in the molding die 9A by the transfer mechanism 10
And are integrally molded with resin.

It is also possible to provide an inspection machine in the middle of the process to judge defective products and discharge the found defective products to the outside of the transport mechanism 5.

[Effects of the Invention] As described above, in the linear body terminal treatment device according to the present invention, the anvil-type jig is conveyed to the ultrasonic welding machine or the transfer mechanism by the transfer mechanism, and the already-welded structure is transferred by the transfer mechanism. Since the metal filament and the metal partner to be welded are transferred to the molding die of the molding machine, the terminal processing can be automated. Particularly, in the transfer mechanism, repeated transfer work is performed so as not to apply a load such as a pulling force or a peeling force that causes breakage or peeling to the welded portion between the already welded metal filament and the metal partner to be welded. Work can be performed easily. Therefore, according to the present invention, it is possible to reduce the burden on the operator, efficiently perform reliable and stable terminal processing work with stable quality, and reduce costs.
