[0002] Some of the transistor's pins are used to connect to the power supply, providing the transistor with the voltage and current required for operation; some pins are used to receive input signals, while other pins are used to output signals processed by the transistor; and the bending of the pins can better fit into the sockets of the circuit board, preventing the transistor from easily falling off when subjected to vibration or external force, thereby improving the stability of the installation; therefore, the transistor pins need to be shaped so that they accurately match the sockets or sockets on the circuit board, facilitating installation and soldering, and improving the efficiency and accuracy of assembly.

[0003] During the bending process of transistor pins, the transistors need to be sent to a specific transistor bending machine for bending. However, after long-term wear and tear, the bending parts of existing bending equipment are easily deformed and cannot achieve the desired bending effect. If the bending parts need to be replaced, professional personnel must be required to replace the internal parts. If the bending parts are damaged and cannot be replaced in time, the pin bending process will be stalled, and subsequent assembly, testing and other links will not be able to proceed normally. The entire production process will be interrupted, resulting in a significant reduction in output. Summary of the Invention

[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] See also Figures 1 to 8 The present invention provides an embodiment of a transistor automatic switching mechanism for processing transistor pins. The transistors in this embodiment are MOS transistors. The transistor automatic switching mechanism includes a platform 10, a Y-axis switching assembly 20, and a Z-axis switching assembly 30. The Y-axis switching assembly 20 includes a Y-axis fixing base 21 mounted on the platform 10, a Y-axis driving cylinder 23 fixed to the Y-axis fixing base 21, and a Y-axis support base 22. The Y-axis driving cylinder 23 has a piston rod, and the Y-axis support base 22 is fixedly connected to the piston rod. The Z-axis switching assembly 30 includes a Z-axis fixing base 31 connected to the Y-axis support base 22, a Z-axis driving mechanism 33 disposed on the Z-axis fixing base 31, and a Z-axis support base 32 connected to the Z-axis driving mechanism 33. A plurality of pin shaping members 34 are mounted on the top of the Z-axis support base 32, extending through the platform 10. Specifically, in this embodiment, each pin shaping member 34 is different; in another embodiment, each pin shaping member 34 is the same; in other embodiments, the pin shaping members 34 may be partially identical and partially different.

[0028] When switching is required in the Y-axis direction, the Y-axis driving cylinder 23 is started, pushing the Y-axis support seat 22 fixed on the Y-axis fixing seat 21 to move along the Y-axis direction; the movement of the Y-axis support seat 22 drives the Z-axis switching assembly 30 connected thereto to change its position as a whole in the Y-axis direction; then, when switching is required in the Z-axis direction, the Z-axis driving mechanism 33 works, driving the Z-axis support seat 32 to move along the Z-axis direction on the Z-axis fixing seat 31; the multiple pin forming parts 34 installed on the top of the Z-axis support seat 32 will change their position in the Z-axis direction as the Z-axis support seat 32 moves, thereby realizing the position adjustment of the pin forming parts 34.

[0029] The transistor automatic switching mechanism can achieve extremely precise position adjustment of the pin shaping piece 34 in three-dimensional space through independent and precise control of the Y-axis and the Z-axis respectively; according to the processing requirements of transistor pins of different types and specifications, multiple pin shaping pieces 34 can be set accordingly, and the positions of the Y-axis and the Z-axis can be flexibly adjusted to fix the required pin shaping piece 34 at a specific position; when the transistor pins to be processed are the same, multiple identical pin shaping pieces 34 are set side by side, and multiple pin shaping pieces 34 work simultaneously, so that multiple transistor pins can be processed at one time; or when the same pin shaping piece 34 In the event of a fault or wear, the pin forming piece 34 that needs processing can be flexibly adjusted along the Y and Z axes. Unfaulted pin forming pieces 34 can be quickly adjusted to their working positions to continue processing, minimizing production delays caused by individual forming piece failures. On the one hand, the same pin forming piece can be used to process the same pin sections simultaneously, improving processing efficiency and allowing the same pin structure of multiple transistors to be processed simultaneously. On the other hand, the flexible adjustment of the Y and Z axes allows the appropriate pin forming piece to be selected for processing different pin sections. This not only meets the processing requirements of some transistor pins with slightly different pins, but also eliminates the need for a completely independent processing mechanism for each slightly different transistor, saving cost and space. The step-by-step, orderly movement of the Y and Z axes reduces unnecessary waiting and adjustment time, and the automated step-by-step movement control reduces the operator's technical requirements and workload.

[0030] See also Figure 1 、 Figure 6 and Figure 7 A plurality of pin inserts 24 are installed on the top of the Y-axis support base 22. The pin inserts 24 are arranged at the upper end of the pin shaping member 34 and are provided with a pin insertion inlet 240. The transistor pins to be processed are placed at the pin insertion inlet 240 of the pin insert 24. As the processing proceeds, the Y-axis support base 22 is driven by the Y-axis drive cylinder 23 to move along the Y-axis direction, so that the pin inserts 24 carry the pins toward the pin shaping member 34. When the pins accurately enter the upper end of the pin shaping member 34 through the pin insertion inlet 240, the pin shaping member 34 begins subsequent processing operations on the pins. The pin insertion inlet 240 can initially position and guide the transistor pins, ensuring that the pins accurately enter the processing position of the pin shaping member 34.

[0031] See also Figure 1 and Figure 8The bottom edge of the pin insertion port 240 extends toward the center with a first limiting step 241. This first limiting step 241 serves as a limit on the pin insertion depth, preventing damage to the pin due to over-insertion or affecting subsequent processing. The stable pin position and accurate insertion depth reduce the time required to adjust the pin position, thereby improving overall processing efficiency. Once the pin is inserted into the pin insertion port 240, the first limiting step 241 limits the pin's horizontal movement, further stabilizing its position. Because the first limiting step 241 ensures that each pin is inserted at a relatively consistent position and depth, the initial state of the pins during batch processing is more uniform.

[0032] See also Figures 1 to 5 A waste discharge channel 242 is provided on the pin insert 24 on one side of the pin forming member 34. A waste discharge pipe 243 extends from the pin forming member 34 toward the waste discharge channel 242. When waste material is generated during machining, it accumulates inside or around the pin forming member 34. Because the waste discharge pipe 243 extends from the pin forming member 34 toward the waste discharge channel 242, the waste material is guided by the waste discharge pipe 243 and enters the waste discharge channel 242 provided on the pin insert 24. The waste discharge pipe 243 promptly removes debris, residue, and other waste materials generated during machining, preventing them from accumulating in the work area and affecting machining accuracy and normal equipment operation.

[0033] The Z-axis drive mechanism 33 includes a Z-axis screw 330 mounted within the Z-axis fixed base 31 and threadedly connected to the Z-axis support base 32; a Z-axis drive motor 331 fixed to one side of the Z-axis fixed base 31; and a belt 332 connected to the Z-axis screw 330 and the rotor of the Z-axis drive motor 331. A Z-axis mounting base 35 is provided on one side of the Z-axis fixed base 31. The housing of the Z-axis drive motor 331 is mounted on the Z-axis mounting base 35. The rotor of the Z-axis drive motor 331 passes through the Z-axis mounting base 35 and is connected to the Z-axis screw 330 via the belt 332. When the Z-axis drive motor 331 is started, its rotor begins to rotate. Since the rotor passes through the Z-axis mounting seat 35 and is connected to the Z-axis screw rod 330 through the belt 332, the rotational motion of the rotor is transmitted to the Z-axis screw rod 330 through the belt 332; the Z-axis screw rod 330 is threadedly connected to the Z-axis support seat 32, and when the screw rod rotates, according to the action of the thread, the Z-axis support seat 32 will produce linear motion along the Z-axis direction; for example, when the rotor of the Z-axis drive motor 331 rotates clockwise, the Z-axis screw rod 330 is also driven by the belt 332 to rotate clockwise, so that the Z-axis support seat 32 moves upward along the Z-axis; conversely, when the rotor rotates counterclockwise, the Z-axis support seat 32 moves downward along the Z-axis; through the threaded connection between the screw rod and the support seat and the transmission of the belt 332, more precise Z-axis linear motion can be achieved, which helps to ensure the quality and accuracy of the product in scenarios requiring high-precision positioning; the structure is relatively stable, and the vibration and error during the transmission process are small, which can provide smooth and reliable Z-axis motion.

[0034] The rotor of the Z-axis drive mechanism 33 is fitted with a first gear ring 333, and the Z-axis screw rod 330 is fitted with a second gear ring 334. The first and second gear rings 333, 334 are connected by a belt 332. After the motor is started, the rotor begins to rotate, driving the first gear ring 333 mounted on the rotor to rotate. Because the first and second gear rings 333, 334 are connected by the belt 332, the rotation of the first gear ring 333 drives the second gear ring 334 to rotate via the belt 332. The second gear ring 334 is fitted over the Z-axis screw rod 330, and its rotation causes the Z-axis screw rod 330 to rotate. The rotation of the Z-axis screw rod 330 causes the Z-axis support 32, to which it is threaded, to move along the Z-axis direction. The combined transmission method of the gear ring and the belt 332 can effectively transmit the power of the motor to the Z-axis screw 330, reduce energy loss and improve transmission efficiency; this transmission method can also achieve precise control of the movement of the Z-axis support seat 32; the belt 332 transmission can play a certain buffering role, making the entire transmission process smoother and reducing vibration and impact.

[0035] Second limiting steps 335 extend outward from both ends of the first and second gear rings 333 and 334. These limiting steps 335 restrict the axial movement of the belt 332 on the gear rings, effectively preventing the belt 332 from slipping off the gear rings during high-speed operation or when subject to external interference. They also prevent the belt 332 from wobbling on the gear rings, reducing abnormal friction and wear between the belt 332 and the edges of the gear rings.

[0036] See also Figure 1 、 Figure 6 and Figure 7 The housing of the Y-axis driving cylinder 23 is fixedly mounted on the Y-axis fixing seat 21, and the piston rod of the Y-axis driving cylinder 23 passes through the Y-axis fixing seat 21 and is connected to the Y-axis support seat 22. When the Y-axis driving cylinder 23 is working, the gas pressure inside the cylinder changes; when the gas is compressed into the cylinder, it pushes the piston in the cylinder to move; the housing of the Y-axis driving cylinder 23 is fixedly mounted on the Y-axis fixing seat 21 and remains stationary; and the piston rod of the cylinder passes through the Y-axis fixing seat 21 and is connected to the Y-axis support seat 22; when the gas pressure in the cylinder increases, the piston is pushed forward, thereby driving the piston rod to extend; since the piston rod is connected to the Y-axis support seat 22, the extension of the piston rod will push the Y-axis support seat 22 to move along the Y-axis direction; conversely, when the gas in the cylinder is discharged, the pressure decreases, the piston retracts, and the piston rod also retracts, thereby pulling the Y-axis support seat 22 to move along the opposite Y-axis direction. The cylinder can quickly respond to changes in gas pressure, achieve rapid expansion and contraction of the piston rod, and thus quickly move the Y-axis support seat 22 in the Y-axis direction; it can provide greater thrust and pull, can easily push or pull heavier loads, and adapt to various load conditions.

[0037] The Y-axis fixed base 21 and the Y-axis support base 22 are respectively provided with a first mounting base 210 and a second mounting base 320. A tank chain 25 for arranging cables is mounted on the first mounting base 210 and the second mounting base 320. When the Y-axis support base 22 moves upward, the tank chain 25, supported and guided by the first mounting base 210 and the second mounting base 320, gradually expands, allowing the cables to smoothly follow the movement of the Y-axis support base 22. Conversely, when the Y-axis support base 22 moves downward, the tank chain 25 gradually contracts and folds, allowing the cables to continue to move in an orderly manner under the protection of the tank chain 25. The expansion and contraction of the tank chain 25 ensures orderly cable movement, preventing cables from becoming entangled or tangled, and protecting the cables from wear, pulling, breakage, and other damage during the frequent movement of the Y-axis support base 22.

[0038] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
