[0002] A diode is an electronic device made of semiconductor materials. A diode has two electrodes, a positive electrode, also called an anode, and a negative electrode, also called a cathode. When a forward voltage is applied between the two electrodes of a 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.

[0003] At present, the welding of diodes is mostly rigid operation. When welding the pins of the diode, if the welding head applies too much force to the diode or produces a rigid collision, it may cause damage to the diode pin or breakage of the welding point, thereby affecting the electrical connection. For this reason, we propose a diode welding buffer device to solve the above problems. Utility Model Content

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] Reference Figure 1 , Figure 2 and Figure 3 As shown, a diode welding buffer device includes a buffer mechanism 1, and the buffer mechanism 1 includes a grip tube 101. The inner wall of the grip tube 101 is provided with four equidistantly distributed slide grooves 102. The interior of the slide groove 102 is fixedly connected with a guide rod 103. The outer surface of the guide rod 103 is slidably connected with a slider 104 that can slide vertically along the slide groove 102. The outer surface of the guide rod 103 is sleeved with a first damping spring 105. The first damping spring 105 is fixedly connected between the slide groove 102 and the slider 104. The interior of the grip tube 101 is slidably connected with a fixed tube 2. The outer side of the fixed tube 2 is fixedly connected to the inner side of the four sliders 104.

[0026] Reference Figure 4 and Figure 5 As shown, an adjusting groove 3 is opened at the top inner side of the fixed cylinder 2, and a bidirectional threaded rod 4 is rotatably connected inside the adjusting groove 3. One end of the bidirectional threaded rod 4 passes through the outer surface of the fixed cylinder 2 and is fixedly connected to an adjusting knob 5 for rotating the bidirectional threaded rod 4. Two symmetrically distributed adjusting plates 6 are threadedly connected to the outer surface of the bidirectional threaded rod 4. A fixing plate 7 is fixedly connected to the lower end of the adjusting plate 6. A plurality of second damping springs 8 are fixedly connected to the inner side of the fixing plate 7. An arc-shaped clamping plate 9 is fixedly connected to the other end of the second damping spring 8, and a welding head 10 is movably connected between the two arc-shaped clamping plates 9.

[0027] Furthermore, the welding head 10 is placed between the two arc-shaped clamping plates 9. By rotating the adjusting knob 5, the bidirectional threaded rod 4 can be driven to rotate, so that the two adjusting plates 6 drive the two arc-shaped clamping plates 9 to approach each other and abut against the surface of the welding head 10, thereby clamping and fixing the welding head 10.

[0028] Furthermore, during the welding process, when the force applied to the pin of the diode is too large, the slider 104 will slide along the guide rod 103 in the vertical direction, thereby compressing the first damping spring 105, and at the same time compressing the second damping spring 8 in the horizontal direction, which can buffer the applied force and reduce the damage caused by the rigid contact between the welding head 10 and the diode pin.

[0029] Reference Figure 2 As shown, the lower end of the fixed cylinder 2 is fixedly connected to the limiting plate 11 , a thread groove 12 is provided on the outer surface of the fixed cylinder 2 near the upper end of the limiting plate 11 , and the lower part of the outer surface of the fixed cylinder 2 is threadedly connected to the supporting cylinder 13 through the thread groove 12 .

[0030] Furthermore, when the welding head 10 is not in use, the support tube 13 can be rotated to move it downward along the surface of the fixed tube 2, thereby storing the welding head 10 in the support tube 13 to prevent the welding head 10 from being exposed to the outside.

[0031] Working principle: When the device is in use, the welding head 10 is placed between the two arc-shaped clamping plates 9 and the top of the welding head 10 is abutted against the inner top of the fixed tube 2, and then the adjusting knob 5 is rotated to make the two-way threaded rod 4 drive the two adjusting plates 6 to approach each other, thereby driving the two arc-shaped clamping plates 9 to abut against the welding head 10. During the welding process, the user holds the grip tube 101 for welding. When the applied force is too large, the first damping spring 105 and the second damping spring 8 will be compressed, thereby reducing the pressure on the diode pin, playing a buffering role, and reducing damage to the diode pin.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
