Description

Technical Field

[0001] This utility model relates to the field of semiconductor transistor processing technology, and in particular to a fixing component for semiconductor transistors. Background Technology

[0002] A transistor is an electronic device made of semiconductor materials. Its core functions are to amplify electrical signals and control the switching of electrical signals. It is an extremely important component of modern electronic devices, and most transistors need to be soldered onto circuit boards for use.

[0003] When soldering semiconductor transistors, if workers manually handle the transistors, it is easy for their sweaty hands to contaminate the transistor surface, causing adverse effects. In addition, it is inconvenient to handle them. Although there are fixtures in the existing technology to assist in handling, it is not convenient to insert the metal leads of the transistor into the circuit board after the transistor is clamped by the fixture.

[0004] Therefore, it is necessary to invent a fixture for semiconductor transistors to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for semiconductor transistors. After clamping the transistor, the orientation of the transistor's metal pins can be adjusted more easily, thereby reducing the difficulty of subsequent insertion into the circuit board. This eliminates the need for operators to frequently adjust their wrists, reducing operational difficulty. This addresses the problem mentioned in the background art where, when soldering semiconductor transistors, manual handling by workers is problematic. Firstly, it easily leads to hand sweat contaminating the transistor surface, causing adverse effects. Secondly, it is inconvenient to handle the transistor. Although existing fixing devices exist to assist in handling the transistor, they do not provide a convenient way to insert the transistor's metal pins into the circuit board after clamping the transistor.

[0006] According to one aspect of this disclosure, a technical solution is provided as follows: a fixing member for a semiconductor transistor, comprising:

[0007] A gripping mechanism, which provides a mounting base for a rotatable clamping mechanism;

[0008] Two sets of symmetrically arranged rotatable clamping mechanisms are used to clamp and fix semiconductor transistors; and

[0009] The pressing drive mechanism includes a gear fixedly sleeved on the outside of an adjacent rotating shaft. A rack is vertically arranged and located inside a clearance hole on one side of the gear. A pressing plate is fixedly connected to the top of the rack. A guide rod B is fixedly arranged on the bottom side of the pressing plate away from the rack, which slides vertically through the top of the first grip rod. A return spring B is sleeved on the outside of the guide rod B and fixedly connected between the pressing plate and the first grip rod.

[0010] According to at least one embodiment of the present disclosure, a holder for a semiconductor transistor includes a gripping mechanism comprising a first gripping rod and a second gripping rod arranged in parallel, wherein a rubber pad is adhesively fixed to the top of the side of the first gripping rod and the second gripping rod away from each other.

[0011] According to at least one embodiment of the present disclosure, a fixing member for a semiconductor transistor has two guide rods A slidably disposed on the side of the second gripping rod away from the first gripping rod. The ends of the two guide rods A away from the second gripping rod are fixedly connected to the first gripping rod. The ends of the two guide rods A near the second gripping rod are fixedly connected to a limiting end plate. A return spring A is sleeved on the outside of each guide rod A and fixedly connected between the first gripping rod and the second gripping rod.

[0012] According to at least one embodiment of the present disclosure, a fixing member for a semiconductor transistor has a cavity inside the first gripping rod and a clearance hole communicating with the cavity is provided at the top.

[0013] According to at least one embodiment of the fixing member for semiconductor transistors of the present disclosure, any set of the rotatable clamping mechanisms includes a rotating shaft, one of the rotating shafts being rotatably nested in the bottom inner side of the bottom of the first gripping rod via a bearing, and the other rotating shaft being rotatably nested in the bottom inner side of the second gripping rod via a bearing.

[0014] According to at least one embodiment of the present disclosure, a fixture for a semiconductor transistor is provided, wherein a clamping plate is fixedly connected to the inner end of the rotating shaft, and a silicone pad is adhered and fixed to the inner side of the clamping plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a pressing drive mechanism. After the transistor is clamped and fixed by two sets of rotatable clamping mechanisms driven by the gripping mechanism, the thumb of the gripping hand can press the pressing plate. When the pressing plate moves downward, it is guided by the guide rod B, compressing the reset spring B and simultaneously driving the rack downward. As the rack moves downward, it drives the adjacent rotating shaft to rotate through the pressing plate. The rotating shaft, in turn, drives the clamped transistor to rotate through the clamping plate and the silicone pad, thereby rotating the metal pins on the transistor from a horizontal position to a downward-facing position, facilitating insertion into the circuit board. Compared to existing technologies, this invention allows for easier adjustment of the orientation of the transistor's metal pins after clamping, reducing the difficulty of subsequent circuit board insertion and eliminating the need for frequent wrist adjustments by the operator, thus simplifying the operation.

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a fixture for a semiconductor transistor according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of a holding mechanism 1 for a fixing member of a semiconductor transistor according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of a rotatable clamping mechanism 2 and a pressing drive mechanism 3 for fixing a semiconductor transistor according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the fixing component for semiconductor transistors disclosed herein may include: a holding mechanism 1, two sets of symmetrically arranged rotatable clamping mechanisms 2, and a pressing drive mechanism 3, etc.

[0030] like Figure 2As shown in this disclosure, the gripping mechanism 1 includes a first gripping rod 11 and a second gripping rod 12 arranged in parallel. Both are made of ABS engineering plastic, which combines lightweight and structural strength, is wear-resistant, and has a moderate cost. Rubber pads 13, made of food-grade silicone, are glued to the top of the sides of the first gripping rod 11 and the second gripping rod 12 away from each other, providing good anti-slip properties and improving grip comfort. Two guide rods A14, made of 304 stainless steel, are slidably disposed through the side of the second gripping rod 12 away from the first gripping rod 11. These guide rods have a smooth and wear-resistant surface, ensuring the smooth sliding of the second gripping rod 12. Smooth operation, not easy to rust, the ends of the two guide rods A14 away from the second grip rod 12 are fixedly connected to the first grip rod 11, and the ends of the two guide rods A14 near the second grip rod 12 are fixedly connected to the limit end plate 15, which is made of stainless steel, has high hardness, and can effectively limit the sliding stroke of the guide rod A14 to prevent the parts from falling off. A return spring A16 is sleeved on the outside of any guide rod A14 and fixedly connected between the first grip rod 11 and the second grip rod 12. The first grip rod 11 has a cavity inside and an avoidance hole 17 connected to the cavity at the top.

[0031] This allows for simultaneous single-handed gripping of both rubber pads 13 to pick up the gripping mechanism 1. Subsequently, after moving the two sets of rotatable clamping mechanisms 2 to both sides of the transistor to be clamped, pressure is applied to the two rubber pads 13, causing the two rubber pads 13 to bring the first gripping rod 11 and the second gripping rod 12 closer together. At this time, the two guide rods A14 guide the second gripping rod 12, while the reset spring A16 is compressed by the second gripping rod 12 and the first gripping rod 11. When it is necessary to release the clamping fixation of the transistor, the hand is gradually relaxed. At this time, the compressed reset spring A16 pushes the second gripping rod 12 to move outward along the two guide rods A14 to reset.

[0032] like Figure 3 As shown, in a preferred embodiment, any set of rotatable clamping mechanisms 2 includes a stainless steel rotating shaft 21, which has high mechanical strength, good stability when rotating with bearings, and is not easily bent. One rotating shaft 21 is nested in the bottom inner side of the first gripping rod 11 via a bearing, and the other rotating shaft 21 is nested in the bottom inner side of the second gripping rod 12 via a bearing. A clamping plate 22 is fixedly connected to the inner end of the rotating shaft 21. The plate is made of reinforced PA plastic, which balances rigidity and lightweight, and avoids damaging the transistor during clamping. A silicone pad 23 is bonded and fixed to the inner side of the clamping plate 22. The pad is made of high-elasticity medical-grade silicone, which is soft and conforms to the surface of the transistor, enhancing the clamping friction and preventing scratches on the transistor shell, while also isolating it from hand contamination.

[0033] Therefore, when actually clamping the transistor, the gripping mechanism 1 drives the two sets of rotatable clamping mechanisms 2 to move to both sides of the transistor to be clamped. Then, the gripping mechanism 1 is gripped so that the gripping mechanism 1 can drive the two rotating shafts 21 to move closer to each other. During this process, the two rotating shafts 21 drive the two clamping plates 22 to move closer to each other until the two silicone pads 23 are tightly attached to both sides of the transistor to be clamped. At this time, the clamping and fixing of the transistor to be clamped is completed. Subsequently, the transistor to be clamped can be moved by moving the gripping mechanism 1.

[0034] like Figure 3 As shown in this disclosure, the pressing drive mechanism 3 includes a gear 31 fixedly sleeved on the outside of the adjacent rotating shaft 21. A rack 32, vertically arranged and located inside the clearance hole 17, meshes with one side of the gear 31. Both the gear and the gear 31 are made of POM engineering plastic, which is wear-resistant and self-lubricating, ensuring smooth transmission without jamming. A pressing plate 33, made of thin aluminum alloy plate, is fixedly connected to the top of the rack 32. It is lightweight and easy to press, and the surface is frosted to improve the pressing feel. A guide rod B34, which slides vertically through the top of the first grip rod 11, is fixedly arranged on the bottom side of the pressing plate 33 away from the rack 32. The guide rod B34 is also made of 304 stainless steel to ensure sliding accuracy and prevent deviation during pressing. A return spring B35, fixedly connected between the pressing plate 33 and the first grip rod 11, is sleeved on the outside of the guide rod B34.

[0035] Therefore, after the transistor is clamped and fixed by the two sets of rotatable clamping mechanisms 2 driven by the gripping mechanism 1, the thumb of the gripping hand can be used to press the pressing plate 33. When the pressing plate 33 moves down, it is guided by the guide rod B34, which compresses the reset spring B35 and drives the rack 32 to move down synchronously. When the rack 32 moves down, it drives the adjacent rotating shaft 21 to rotate through the pressing plate 33. The rotating shaft 21 then drives the clamped transistor to rotate through the clamping plate 22 and the silicone pad 23, thereby rotating the metal pins on the transistor from the original horizontal state to the downward state, which is convenient for insertion into the circuit board. Compared with the prior art, after the transistor is clamped, the orientation of the transistor metal pins can be adjusted more easily, thereby reducing the difficulty of subsequent insertion into the circuit board. The operator does not need to frequently adjust their wrist, which reduces the difficulty of operation.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
