Description

Technical Field

[0001] This application relates to the technical field of MOS transistor processing equipment, and particularly relates to a MOS transistor lead cutting device. Background Art

[0002] MOS transistors, namely metal-oxide-semiconductor field-effect transistors, are widely used in electronic devices. Usually, multiple leads are welded on the MOS transistor for connection with the outside world. When these leads are processed, for the sake of improving efficiency, they are often made into a unified length.

[0003] However, in actual application scenarios, the length requirements of the leads vary according to their specific usage conditions. Especially in high-frequency and high-precision motors, subtle changes in the lead length will cause differences in capacitance distribution, thus leading to significant changes in the motor performance. Therefore, it is particularly important to precisely trim the leads before use.

[0004] At present, the trimming of MOS transistor leads mainly relies on manual operation. Usually, the staff holds the MOS transistor with one hand and uses scissors or a special cutter to cut the leads with the other hand. However, this method has many deficiencies in the using process, such as poor operation stability and difficult-to-guarantee cutting accuracy. It not only easily affects the product quality but also may cause waste of resources and increase production costs. Summary of the Utility Model

[0005] In order to solve the problem that the method of manually cutting the leads easily affects the quality of the cut leads and increases the production cost, this application provides a MOS transistor lead cutting device.

[0006] A MOS transistor lead cutting device provided by this application adopts the following technical solutions:

[0007] A MOS transistor lead cutting device, which includes a mounting base. A first cutter and a second cutter are arranged on the mounting base. The first cutter and the second cutter are arranged oppositely. The second cutter slides on the mounting base along the direction of approaching or departing from the first cutter. A positioning structure for positioning the leads is arranged on the mounting base. A driving component for driving the second cutter to slide is arranged on the mounting base.

[0008] By adopting the above technical solution, when in use, place the MOS tube lead between the first cutting knife and the second cutting knife, and position the lead through the positioning structure, so as to ensure the stability of the lead during the cutting of the lead. At the same time, the distance between the positioning structure and the mounting base remains unchanged all the time, so as to ensure that the cutting length of the lead always remains consistent. Then, drive the second cutting knife to slide towards the first cutting knife through the driving component until the blade of the second cutting knife abuts against the blade of the first cutting knife, so as to cut off the lead, thereby realizing the cutting process of the lead. The use is simple and convenient.

[0009] Preferably, the driving component includes a control switch and a driving cylinder fixed on the mounting base. The cylinder body of the driving cylinder is fixed on the mounting base, and the piston rod of the driving cylinder is detachably connected to the second cutting knife. The control switch is used to control the telescopic movement of the piston rod of the driving cylinder.

[0010] By adopting the above technical solution, when in use, the staff controls the telescopic movement of the piston rod of the driving cylinder by adjusting the closing of the control switch, so as to drive the second cutting knife to slide towards or away from the first cutting knife, thereby realizing the cutting of the lead. The use is simple and convenient.

[0011] Preferably, the positioning structure includes a positioning block detachably connected to the mounting base. A cutting cavity is formed between the positioning block and the mounting base. The positioning block is provided with a limiting hole for inserting and positioning the lead. The limiting hole communicates with the cutting cavity. Both the first cutting knife and the second cutting knife are located in the cutting cavity, and the first cutting knife and the second cutting knife are respectively located on both sides of the limiting hole. The first cutting knife is detachably connected to the positioning block, and the second cutting knife is slidably inserted into the cutting cavity.

[0012] By adopting the above technical solution, when in use, insert the lead into the limiting hole. When a part of the lead exposes from the cutting cavity, the staff can pull the lead to make the tube body of the MOS tube abut against the mounting base, so as to realize the positioning of the lead, thereby ensuring the stability of the lead during the cutting process of the lead, and at the same time ensuring that the length of the cut lead always remains consistent. The overall use is simple and convenient.

[0013] Preferably, an avoidance groove is formed on the mounting base, and the avoidance groove, the cutting cavity and the limiting hole communicate with each other.

[0014] By adopting the above technical solution, when in use, by setting the avoidance groove, on the one hand, it is convenient for the staff to pull the lead to make the tube body of the MOS tube abut against the mounting base; on the other hand, it prevents the lead from piling up in the cutting cavity when the lead is too long, which is likely to affect the cutting quality of the lead.

[0015] Preferably, a sliding rod is slidably arranged on the positioning block. The sliding rod slides along the depth direction of the limiting hole. A clamping block is fixed on the sliding rod. A clamping groove for clamping the lead angle is formed on the clamping block. An adjusting component for adjusting the sliding length of the sliding rod is arranged on the positioning block.

[0016] By adopting the above technical solution, during use, the lead angle is first passed through the clamping groove and then into the limiting hole until the tube body of the MOS transistor abuts against the clamping block. At this time, according to the different lengths of the lead angle to be cut, the sliding distance of the clamping block can be adjusted through the adjusting component, thereby driving the tube body of the MOS transistor to slide, so as to achieve the purpose of cutting the lead angle according to the use requirements.

[0017] Preferably, the adjusting component includes a gear rotatably arranged on the positioning block and a driving member for driving the gear to rotate. A rack is fixed on the side wall of the sliding rod, and the rack meshes with the gear.

[0018] By adopting the above technical solution, during use, through the mutual cooperation of the gear and the rack, the gear can be driven to rotate by the driving member, so as to achieve the purpose of driving the gear to move and then driving the sliding rod to slide.

[0019] Preferably, scale lines are arranged on the sliding rod.

[0020] By adopting the above technical solution, during use, by arranging the scale lines, it is convenient for the staff to accurately adjust the sliding length of the sliding rod, so as to achieve the purpose of accurately controlling the length of the lead angle to be cut off.

[0021] Preferably, a storage box is arranged on the mounting seat, and the storage box is located below the avoidance groove.

[0022] By adopting the above technical solution, during use, by arranging the storage box, it is convenient for the staff to collect the waste of the cut-off part of the lead angle, which is more convenient to use.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. During use, by passing the lead angle into the limiting hole and continuing to pull the lead angle until the tube body of the MOS transistor abuts against the mounting seat, the lead angle can be positioned on the premise of ensuring the stability of the lead angle placement. Then, the second cutting tool is driven to slide by the driving cylinder and used in cooperation with the first cutting tool, so as to cut off the lead angle, and at the same time ensure that the length of the lead angle after cutting is always consistent, thereby improving the cutting quality of the lead angle, avoiding material waste, and saving the processing cost of the lead angle;

[0025] 2. During use, by setting the sliding rod, gear and rack, the purpose of cutting the leading angle to a specified length according to the usage requirements during the cutting process of the leading angle is achieved, thereby achieving the purpose of accurately controlling the length of the cut leading angle.

[0026] 3. During use, by setting the storage box, it is convenient for the staff to collect the waste of the cut part of the leading angle, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 7 drawings.

[0036] Embodiment 1 of the present application discloses a MOS transistor lead cutting device.

[0037] Embodiment 1:

[0038] Refer toFigure 1 , a MOS transistor lead cutting device, including a horizontally placed mounting base 1. The mounting base 1 is composed of a bottom plate 11, columns 12 and a top plate 13. The bottom plate 11 and the top plate 13 are arranged in parallel, and the top plate 13 is located directly above the bottom plate 11. The bottom ends of the columns 12 are welded to the bottom plate 11, and the top ends of the columns 12 are fixedly welded to the top plate 13. There are multiple columns 12, and the multiple columns 12 are distributed around the perimeter of the bottom plate 11. In this embodiment, the columns 12 are preferably set to four.

[0039] Refer to Figure 1 and Figure 2 , a first cutter 2 and a second cutter 3 are placed on the top plate 13. The cutting edges of the first cutter 2 and the second cutter 3 are arranged oppositely. The second cutter 3 slides on the top plate 13 along the length direction of the top plate 13. A driving component 5 and a positioning structure 4 are arranged on the top plate 13. The driving component 5 is used to drive the second cutter 3 to slide, and the positioning structure 4 is used to position the lead; when in use, when the driving component 5 controls the second cutter 3 to slide towards the first cutter 2, the lead can be cut by the cooperation of the first cutter 2 and the second cutter 3. When the driving component 5 controls the second cutter 3 to slide away from the first cutter 2, it is convenient for the staff to replace the lead to be cut.

[0040] Refer to Figure 3 , the driving component 5 includes a control switch 51 and a driving cylinder 52. The control switch 51 is used to control the telescopic movement of the piston rod of the driving cylinder 52. The control switch 51 can be selected from pneumatic valves, solenoid valves, etc. In this embodiment, the control switch 51 is preferably set as a pneumatic mechanical valve. A ventilation pipe for connecting to an external air pump, an intake pipe and an exhaust pipe for communicating with the driving cylinder 52 are connected to the pneumatic mechanical valve; when in use, the staff adjusts the pneumatic mechanical valve to connect the ventilation pipe with the intake pipe, and the piston rod of the driving cylinder 52 can be extended. By adjusting the pneumatic mechanical valve to connect the ventilation pipe with the exhaust pipe, the piston rod of the driving cylinder 52 can be retracted.

[0041] Refer to Figure 2 and Figure 4, a relief groove 7 is provided at the right end of the top plate 13, and the positioning structure 4 is located above the relief groove 7. The positioning structure 4 includes a positioning block 41. An installation groove 411 is provided on the bottom surface of the positioning block 41. The first cutter 2 is embedded in the installation groove 411, and the first cutter 2 is connected to the positioning block 41 by bolts. A through hole 412 is provided on the side wall of the positioning block 41, and the through hole 412 communicates with the installation groove 411. One end of the second cutter 3 is slidably inserted into the through hole 412, and the other end of the second cutter 3 is connected to the piston rod of the driving cylinder 52 by bolts; during use, both the first cutter 2 and the second cutter 3 can be disassembled by screwing the bolts, so as to facilitate the maintenance or replacement of the first cutter 2 and the second cutter 3 by the staff; at the same time, the sliding of the second cutter 3 can be guided through the through hole 412, thereby increasing the stability of the cutting process of the second cutter 3.

[0042] Refer to Figure 2 and Figure 5 , the positioning block 41 is bolted to the top plate 13. After the positioning block 41 is fixed to the top plate 13 by bolts, a cutting cavity 6 can be formed between the positioning block 41 and the top plate 13. A limiting hole 42 is provided through the top surface of the positioning block 41. The limiting hole 42, the cutting cavity 6 and the relief groove 7 communicate with each other. The first cutter 2 and the second cutter 3 are respectively located on both sides of the limiting hole 42, and the cutting edge of the second cutter 3 slides in the cutting cavity 6.

[0043] Refer to Figure 2 and Figure 5 , during use, the depths of the limiting hole 42 and the cutting cavity 6 are always fixed. Therefore, when the lead angle is inserted into the limiting hole 42 and the body s of the MOS transistor abuts against the top plate 13, the distance between the body of the MOS transistor and the cutting position of the lead angle is fixed, so as to ensure that the cut part of the lead angle is consistent each time. At the same time, the relief groove 7 can prevent the cut lead angle from being too long and accumulating in the cutting cavity 6, thereby avoiding the influence of the too long lead angle on the movement of the second cutter 3.

[0044] The implementation principle of the embodiment of the present application is as follows: During use, the staff inverses the lead angle so that the body of the MOS transistor faces upward and the lead angle faces. Then, the lead angle can be moved downward to be inserted into the limiting hole 42 and pass through between the first cutter 2 and the second cutter 3 until it passes out from below the relief groove 7. Then, the staff can pull the lead angle until the body of the MOS transistor abuts against the top surface of the top plate 13. Then, by activating the control switch 51, the piston rod of the driving cylinder 52 extends, thereby driving the second cutter 3 to slide. By approaching the second cutter 3 to the first cutter 2, the purpose of cutting the lead angle can be achieved. By cutting the lead angle in this way, on the one hand, it can ensure that the cut part of the lead angle always remains the same length, and on the other hand, it can ensure the stability of the cutting process of the second cutter 3, thereby ensuring the quality of the cut lead angle, effectively reducing resource waste, and saving production and processing costs.

[0045] The difference between the second embodiment and the first embodiment is that:

[0046] Referring to Figure 6 and Figure 7 Figure 7 , a sliding rod 8 is further slidably arranged on the positioning block 41. The sliding direction of the sliding rod 8 is the vertical direction. A clamping block 9 is welded to the top end of the sliding rod 8. A clamping groove 91 is formed through the clamping block 9. In this embodiment, the opening size of the clamping groove 91 is the same as that of the limiting hole 42, and the clamping groove 91 is located directly above the limiting hole 42. The clamping groove 91 is used for threading the lead angle. The clamping block 9 is used to support the tube body of the MOS tube and drive the MOS tube to move up and down. In order to facilitate the insertion of the lead angle into the clamping groove 91, a guiding inclined surface is formed at the edge of the notch of the clamping groove 91.

[0047] Referring to Figure 6 and Figure 7 Figure 7 , an adjusting assembly 10 is arranged on the positioning block 41. The adjusting assembly 10 is used to adjust the lifting height of the sliding rod 8. The adjusting assembly 10 includes a gear 101 and a driving member 102. The gear 101 rotates on the positioning block 41. The driving member 102 is installed on the positioning block 41. The driving member 102 is used to drive the gear 101 to rotate. The driving member 102 can be selected as a motor, a handwheel, etc. In this embodiment, the driving member 102 is preferably set as a handwheel. The handwheel is coaxially connected to the gear 101. A rack 103 is integrally formed on the side wall of the sliding rod 8. The rack 103 meshes with the gear 101.

[0048] Referring to Figure 6 and Figure 7 Figure 7 , when in use, the staff drives the gear 101 to rotate by rotating the handwheel. The rotation of the gear 101 drives the rack 103 to slide vertically, so as to realize the adjustment of the height of the sliding rod 8. At the same time, a scale line 81 is also integrally formed on the side wall of the sliding rod 8. When in use, the staff can adjust the lifting of the sliding rod 8 according to the scale line 81, so as to realize the purpose of accurately controlling the lifting height of the sliding rod 8, and further realize the purpose of accurately controlling the cutting length of the lead angle.

[0049] Referring to Figure 6 Figure 6 , at the same time, in order to facilitate the staff to collect and sort out the waste after the lead angle is cut off, a storage box 20 is further placed on the bottom plate 11. The upper end of the storage box 20 is open, and the storage box 20 is located directly below the avoidance groove 7.

[0050] The implementation principle of the embodiment of this application is as follows: When in use, the staff can adjust the height of the sliding rod 8 by rotating the handwheel according to the required length of the lead angle. After the distance between the top surface of the clamping block 9 and the cutting edge of the second cutter 3 meets the length of the lead angle to be cut, the lead angle can be first inserted into the clamping groove 91, then passed through the limiting hole 42 and the cutting chamber 6, and then passed out through the avoidance groove 7. Then, pull the lead angle to make the tube body of the MOS transistor abut against the clamping block 9. After that, the staff can control the telescopic movement of the piston rod of the driving cylinder 52 through the control switch 51, so as to cut off the lead angle through the second cutter 3 and the first cutter 2, thereby achieving the purpose of accurately controlling the cutting length of the lead angle and making the use more convenient.

[0051] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
