Description

Technical Field

[0001] This utility model relates to the field of transistor welding technology, specifically a positioning device for transistor production. Background Technology

[0002] A transistor is a key electronic component primarily used for amplifying and switching electrical signals. It consists of three regions: the base (B), the emitter (E), and the collector (C). Transistors are classified into two types: NPN and PNP, differing in current direction and voltage polarity. In amplification mode, the emitter is forward-biased, and the collector junction is reverse-biased. A small change in the base current leads to a large change in the collector current, thus amplifying the signal. In switching mode, a transistor can switch between saturation (conduction) and cutoff (discontinuity) states, functioning similarly to a switch.

[0003] When soldering transistors to connecting wires, existing positioning devices are inconvenient for quickly positioning the transistors and connecting wires, which affects the soldering efficiency. At the same time, the soldering point between the transistor pins and the connecting wires will rise in temperature after a long period of spot welding, which can easily cause burns to the transistors and connecting wires. To solve the above problems, this application proposes a positioning device for transistor production. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figure 1-4 As shown, the present invention proposes a positioning device for transistor production, including a positioning fixture 1, wherein transistor limiting grooves 2 are equidistantly opened on the surface of the positioning fixture 1, and a wire limiting groove 3 is opened on one side of the transistor limiting grooves 2.

[0029] The positioning fixture 1 is rotatably provided with a connecting shaft 5, and a pressure plate 6 is rotatably connected to the surface of the positioning fixture 1 through the connecting shaft 5. The pressure plate 6 presses against the surface of the positioning fixture 1.

[0030] A pressure rod 9 is movably provided above the wire limiting groove 3. A wire pressing seat 10 is provided on the lower surface of the pressure rod 9 at a position corresponding to the wire limiting groove 3. The wire pressing seat 10 is inserted into the wire limiting groove 3.

[0031] The positioning fixture 1 has guide seats 12 welded to both ends of its surface. A guide rod 11 is movably inserted into the inner cavity of the guide seat 12. The top of the guide rod 11 is connected to both ends of the pressure rod 9.

[0032] A spot welding groove 4 is provided in the middle of the wire limiting groove 3, and air guide grooves 15 are provided on both sides of the spot welding groove 4.

[0033] It should be noted that the transistor and connecting wire are placed in the transistor limiting groove 2 and the connecting wire limiting groove 3 on the surface of the positioning fixture 1, respectively. The transistor limiting groove 2 and the connecting wire limiting groove 3 limit the transistor and the connecting wire, respectively. The contact pin on the transistor and the end of the connecting wire coincide in the spot welding groove 4. The pressure plate 6 is flipped by the connecting shaft 5. The lower surface of the pressure plate 6 is pressed against the surface of the transistor by the rubber pad 14. At the same time, the electromagnet 8 generates magnetism after being energized. The electromagnet 8 attracts the metal adsorption seat 7, which can lock the pressure plate 6 and realize the rapid limiting of the transistor. At the same time, the support spring 13 pushes the guide rod 11 bracket downward. The guide rod 11 drives the pressure rod 9 to descend. The lower surface of the pressure rod 9 is inserted into the connecting wire limiting groove 3 through the connecting wire pressure seat 10, which can quickly position the connecting wire. The spot welding machine can quickly weld the transistor and the connecting tube in the spot welding groove 4, which can improve the welding efficiency and welding accuracy of the transistor.

[0034] In this embodiment, as Figure 3 As shown, metal adsorption seats 7 are welded to both ends of the pressure plate 6. The cross-section of the metal adsorption seat 7 is a right-angle structure. Electromagnets 8 are installed on both ends of the positioning fixture 1 at positions corresponding to the metal adsorption seats 7. When the electromagnets 8 are energized, they are magnetically attracted to the metal adsorption seats 7.

[0035] It should be noted that the electromagnet 8 generates magnetism after being energized, and the electromagnet 8 attracts the metal adsorption seat 7, which can lock the pressure plate 6.

[0036] In this embodiment, as Figure 3 As shown, a support spring 13 is sleeved on the guide rod 11, and the support spring 13 is located below the guide seat 12.

[0037] It should be noted that the downward thrust of the support spring 13 on the guide rod 11 bracket causes the guide rod 11 to drive the pressure rod 9 to descend, which can achieve rapid positioning of the connecting wire.

[0038] In this embodiment, as Figure 3 As shown, a rubber pad 14 is embedded on the lower surface of the pressure plate 6, and the rubber pad 14 presses against the surface of the transistor.

[0039] It should be noted that when the pressure plate 6 positions the transistor, the rubber pad 14 presses against the surface of the transistor, which can protect the transistor.

The positioning fixture 1 has an air supply fan 17 on one side, and the exhaust end of the air supply fan 17 is connected to the gas collection hood 16 through a pipe.

[0041] It should be noted that the air blower 17, in conjunction with the air collection hood 16, can blow air into the air guide groove 15. The air is discharged from both sides of the spot welding groove 4, which can quickly dissipate heat from the spot welding groove 4 at the welding point, thereby reducing the temperature inside the spot welding groove 4 and preventing burns when handling connecting wires, thus improving safety during use.

[0042] The working principle and usage process of this utility model are as follows: The transistor and connecting wire are placed in the transistor limiting groove 2 and connecting wire limiting groove 3 on the surface of the positioning fixture 1, respectively. The transistor limiting groove 2 and connecting wire limiting groove 3 respectively limit the transistor and connecting wire. The contact pin on the transistor coincides with the end of the connecting wire in the spot welding groove 4. The pressure plate 6 is flipped by the connecting shaft 5. The lower surface of the pressure plate 6 is pressed against the surface of the transistor by the rubber pad 14. At the same time, the electromagnet 8 generates magnetism after being energized, and the electromagnet 8 attracts the metal adsorption seat 7, which can lock the pressure plate 6, achieving rapid limiting of the transistor and supporting it. The spring 13 pushes the guide rod 11 bracket downwards, and the guide rod 11 drives the pressure rod 9 to descend. The lower surface of the pressure rod 9 is inserted into the wire limiting groove 3 through the wire pressure seat 10, which can quickly position the connecting wire. The spot welding machine can quickly weld the transistor and the connecting pipe in the spot welding groove 4, which can improve the welding efficiency and welding accuracy of the transistor. The air blower 17 and the air collection hood 16 can blow air into the air guide groove 15. The air is discharged from both sides of the spot welding groove 4, which can quickly dissipate heat from the welding point of the spot welding groove 4, reduce the temperature inside the spot welding groove 4, prevent burns when handling the connecting wire, and improve the safety during use.
