2. Description of the Related Art Conventionally, a method and apparatus for automatically supplying electric power to an electric component having a lead wire is a semi-automatic device or a lead in which a power source connecting work is manually performed because it is difficult to restrain and position the lead wire. There are methods such as connecting the wires to the terminal board and pressing the electrode pins to the terminals to supply power.
It cannot be used to automatically power lead wires that are completely free. For this reason, an automated apparatus for supplying electric power to an electric component, which is a finished product in a lead-free state, for assembling, inspecting, etc., requires an apparatus such as that of the present invention.

[0003]

In an automatic assembly and inspection process of an electric component having a lead wire, for example, a lamp or the like, the finished product is a lead wire-free automation device which requires work for supplying electric power. Then, it is indispensable to accurately restrain and position the lead wire and supply electric power. The method of fixing the lead wire to the terminal board and pressing the electrodes to supply electric power makes manual work such as fixing the lead wire difficult, and makes it difficult to completely automate the supply and delivery of parts. .

An object of the present invention is to automatically supply electric power to an electric component having a lead wire in a completely free state in order to configure a complete automation device from supply of component to payout. Since it is composed of an air-driven cylinder and a clamp mechanism, it is a simple mechanism and control system, and it is to provide a system that stably and continuously supplies electric power.

[0005]

In order to achieve a method and apparatus for automatically supplying electric power to an electric component having a lead wire according to claim 1, an air driven chuck for clamping lead wires of positive and negative electrodes having different lengths. And an air cylinder that moves the drive chuck up and down to clamp the lead wire near the connection between the lead wire and the electrode pin of the electric component. Achieve lead wire positioning.

In order to achieve the method for supplying electric power according to the second aspect of the present invention, the conductive electrode plates and the air for opening and closing the conductive electrode plates are provided on both sides of the lead wire conducting portions having different lengths of the positive and negative electrodes that are constrained. Power is supplied by forming a cylinder and clamping the positive and negative electrode lead wires with an electrode plate.

As a method for adjusting and managing the lead wire clamping force of the electrode plate according to the third aspect, a pressure reducing valve for adjusting the driving air pressure of the air cylinder that opens and closes the electrode plate is configured to control the driving air pressure. ， By controlling, achieve stable lead wire clamping.

A method for automatically supplying electric power to an electric component having a lead wire is as follows. A lead wire having positive and negative electrodes having different lengths is clamped by a chuck near an electrode pin of the electric component and a lead wire connecting portion, and the chuck is led by an air cylinder. By pulling down toward the terminal, stable positioning of the lead wire to the electrode portion that supplies power is achieved. The lead wire clamp is configured so that bending and spreading of the lead wire can be corrected by pulling it down with the cylinder of the clamp chuck without applying a clamping force to the lead wire, and by preventing the displacement of the electric parts when pulling down the clamp chuck, Improve device reliability.

The electric power is supplied by clamping the lead wires by opening and closing the electrode plates conducted on both sides of the positive and negative electrode lead wire conducting portions having different positioned lengths by the air cylinder. The tip of the electrode plate that clamps the lead wire conducting portion has a curved shape to prevent breakage of the lead wire during clamping and short circuit of the power supply due to damage to the coating of the upper electrode that clamps the two lead wires.

Regarding the control of the clamping force, the air cylinder thrust is controlled by adjusting the pressure value measured by the pressure reducing valve provided in the drive air introducing portion of the air cylinder that drives the electrode plate to open and close.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an overall view. This device automatically supplies power to halogen lamps with lead wires,
It is a device for adjusting the optical axis. The automatic power supply device includes a lead wire positioning mechanism and a power supply mechanism. The lamp 1 to which the lead wire 8 is connected is clamped by an adjusting arm 2 that adjusts the optical axis. Since the position of the end portion of the lead wire 8 in the free state is unstable, the position of the lead wire 8 does not vary due to the clamp chuck vertical cylinder 5 in the lead wire clamp chuck 3 with the clamp arm 4 opened. The clamp wire 3 is moved to the position, the clamp chuck 3 is closed, and the lead wire 8 is restrained by the clamp arm 4. The clamp arm 4 can restrain the lead wire 8 in the front-rear direction and the left-right direction, and does not apply an external force to the lead wire 8. By moving the clamp chuck upper and lower cylinders 5 to the lower position while the lead wire 8 is being restrained, the conductive portion of the lead wire 8 is positioned at the opening / closing position of the electrode plate 7.

The conducting parts of the two lead wires 8 of the positioned anode and cathode are constructed so that the anode is short and the cathode is long so that short circuit does not occur. Anode and cathode lead wires 8
On both sides of the conducting part of the electrode plate 7, an electrode plate 7 which is electrically connected by a conductor 6 and which can be opened and closed by an electrode plate opening / closing cylinder 9 is provided.
To the conducting portion of the lead wire 8 by closing the electrode plate 7
Is pressed to achieve the supply of electric power from the power source 10 to the lamp 1, and the lamp 1 is turned on.

The electrode plate opening / closing cylinder 9 is driven by applying a pressure controlled and controlled by the pressure sensor 11 and the pressure reducing valve 12 through the air pipe 14 by the solenoid valve 13, and by controlling this pressure, Achieving stable control and management of the clamping force of the electrode plate 7.

As described above, stable automatic power supply to the leaded electric component is achieved.

[0015]

According to the present invention, since the lead wire of the electric component with the lead wire can be easily restrained and positioned, automatic power supply can be stably performed. Since the structure is a simple structure using an air cylinder, disassembly, maintenance and inspection are not required. The device configured with a small number of parts facilitates incorporation into an automatic machine and has stable and high performance as an automatic power supply device for electric parts having lead wires.
