Description

Technical Field

[0001] The invention relates to the field of diode welding, and in particular to a diode production welding device which is easy to position. Background Art

[0002] A diode is an electronic device made of semiconductor materials. A diode has two electrodes, the positive electrode, also called the anode, and the negative electrode, also called the cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on, and when a reverse voltage is applied, the diode is turned off. The conduction and cutoff of a diode are equivalent to the on and off of a switch. A diode needs to be installed in a designated location such as a circuit board to play its role. Usually, the installation method on a circuit board is through soldering. Soldering is a welding method that uses low-melting-point metal solder to heat and melt, penetrate and fill the gap between metal parts.

[0003] In the welding process of the existing diode, since the pins of the diode are in a straight state, they need to be bent and inserted into the reserved welding holes on the circuit board before welding. The reserved welding holes on the circuit board are designed in advance. At this time, it takes a lot of time to bend the pins of the diode according to the spacing between the two groups of welding holes, and they need to be plugged in after bending. Since the size of the diode is generally small, it is inconvenient to plug in. If the plugging is not in place, it is easy to cause cold soldering after welding, which greatly increases the difficulty of welding the diode and reduces its welding efficiency.

[0004] Therefore, it is necessary to invent a diode production welding device that is easy to position to solve the above problems. Summary of the invention

[0048] Furthermore, in the above structure, multiple groups of electric push rods 409 are installed on the upper inner wall of the protective box 206, and push plates 410 are installed on the output ends of the multiple groups of electric push rods 409.

[0049] The bending half-cylinder 404 moves along the guide half-cylinder 401 , so that the bending half-cylinder 404 drives the connecting frame 408 to move and cooperates with the positioning slide 415 to drive the T-shaped block 412 to move along the card slot 411 .

[0050] like Figure 1-7As shown, the second placement frame 305 is rotated and opened by the lock 307. At this time, the diode is placed between the placement frame 1 304 and the placement frame 2 305, and the pins on both sides of the diode pass through the through slot 306 and penetrate the bending half cylinder 404. At this time, the circuit board is placed in the placement slot 209 in the fixed frame 208. At this time, the push plate 410 is pushed to move by the electric push rod 409, so that the positioning slide 415 slides along the connecting frame 408, and the bending rod 414 is attached to the bending half cylinder 404 to bend the pins of the diode. At the same time, as the electric push rod 409 continues to press downward, the guide rod 302 slides along the fixing plate 301, so that the push frame 303 gradually moves downward, and at the same time, the servo motor 203 drives the threaded rod 202 to rotate, so that the connecting seat 205 moves, in this way the fixing frame 208 and the protective box 206 are adjusted to the corresponding positions, and the pins move downward and are just inserted into the soldering holes reserved on the circuit board. At this time, the pins are soldered to the circuit board through the tin soldering pads 207, and the bolts 407 can be rotated to move along the internal thread block 403, so that the bending half cylinder 404 moves along the guide half cylinder 401, thereby changing the length of the guide half cylinder 401 and the bending half cylinder 404. At the same time, under the action of the connecting frame 408 and the positioning slide 415, the bending rod 414 can follow the movement and adjustment. In this way, the corresponding adjustment can be made according to the bending length required by the pins of the diode. In this way, the welding difficulty of the diode can be reduced and the welding efficiency can be improved.
