Description

Technical Field

[0001] This utility model belongs to the technical field of pin forming device, specifically, it relates to an electronic component pin cutting device. Background Technology

[0002] Electronic components with pins need to have their pins shaped (including bending and / or cutting, achieved through different processing dies) to facilitate subsequent assembly.

[0003] A common way to handle pins is to cut the pins of electronic components. The pin cutting is mainly achieved by a pin cutting mechanism, which consists of a moving cutter and a stationary cutter on two different bases. The moving cutter moves relative to the stationary cutter to cut the pins of the electronic components that are fed between the moving cutter and the stationary cutter.

[0004] When the pin length of the electronic component to be cut changes, the pin cutting device needs to be changed to achieve the effect of changing the pin length. Therefore, in order to achieve the cutting of different pin lengths as much as possible and to be more compatible with a variety of electronic component products, the entire pin-cutting machine will have multiple pin-cutting mechanisms arranged side by side to cut out electronic component pins of different lengths. However, this setting method cannot be compatible with all electronic components, and the compatibility range is limited. In addition, setting up multiple sets of pin-cutting mechanisms will also greatly increase the production cost of the entire pin-cutting machine.

[0005] In addition, some cutting mechanisms have two adjustable bases to achieve different cutting lengths. Structurally, an adjustment hole is set on the base, which is fixed to the forming machine in conjunction with a locking screw. During adjustment, the adjustment screw is loosened manually, and then the base moves relative to the locking screw through the adjustment hole above it to adjust its position. However, manual adjustment is inconvenient, time-consuming and laborious.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0056] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0057] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0058] In some embodiments of this application, an electronic component pin-cutting device is proposed. The electronic component, such as a widely used rectifier bridge rectifier, has multiple pins on its top, and the multiple pins are arranged side by side at a certain interval.

[0059] Electronic components can be assembled onto corresponding electronic devices to form electrical connections for application.

[0060] Different electronic components require different pin lengths when mounted on different electrical devices.

[0061] In order for electronic components to meet the installation and use requirements of electrical appliances, the pins of electronic components need to be processed and shaped by a molding device.

[0062] In some embodiments of this application, the electronic component lead cutting device includes a molding base 100 and a first lead cutting mechanism 200 and a second lead cutting mechanism 300 assembled on the molding base 100. The first lead cutting mechanism 200 and the second lead cutting mechanism 300 cooperate to partially cut off the leads of the electronic component so that the lead length of the electronic component meets the usage requirements.

[0063] The molding base 100 is used to form the base of the entire molding device, and it serves to assemble and support the first cutting mechanism 200 and the second cutting mechanism 300.

[0064] During assembly, the first cutting mechanism 200 is assembled to one end of the forming base 100;

[0065] The second cutting mechanism 300 is assembled to the other end of the first cutting mechanism 200 and cooperates with the first cutting mechanism 200 to form the cutting of electronic component pins.

[0066] The first cutting mechanism 200 and the second cutting mechanism 300 are arranged opposite to each other, and a cutting receiving space 440 is formed between the first cutting mechanism 200 and the second cutting mechanism 300. When the pins of the transported electronic components pass through the cutting receiving space 440, the pins are cut off by the opposing movement of the two cutting mechanisms.

[0067] In some embodiments of this application, the first cutting mechanism 200 includes: a first power telescopic component 210;

[0068] A first sliding member 220 is slidably connected to the molding base 100 and is connected to a first power telescopic member, which can extend and retract under the drive of the first power telescopic member.

[0069] The first cutting tool 230 is detachably connected to the first sliding member 220.

[0070] The first power telescopic component 210 is a first telescopic cylinder, which includes a first cylinder body and a first telescopic rod connected to the first cylinder body.

[0071] The first sliding member 220 is connected to the first telescopic rod and can slide and extend under the action of the first telescopic member.

[0072] The first cutting blade 230 is connected to the first sliding member 220. When the first sliding member 220 is extended or retracted by the first telescopic rod, the first cutting blade 230 is simultaneously driven to extend or retract.

[0073] In some embodiments of this application, the first sliding member 220 is a first sliding block, which can be a cuboid or a cube, and is connected to the first telescopic rod through a first connecting member.

[0074] In a specific configuration, a T-shaped groove is provided on the first sliding member 220, and a T-shaped connector is provided on the first connecting member. The first connecting member is engaged in the T-shaped groove from top to bottom through the T-shaped connector to achieve a transmission connection with the first telescopic member, thereby realizing the connection between the first cutting blade 230 and the first power telescopic component 210.

[0075] When it is necessary to disassemble and replace the first cutting blade 230, the first sliding member 220 and the first cutting blade 230 can be removed from the first telescopic rod in the direction from top to bottom. Through the T-shaped groove and T-shaped connector, the first cutting blade can be quickly disassembled and installed, which facilitates the replacement of the first cutting blade.

[0076] The first cutting tool 230 is attached to the first sliding member 220 and is fixed together with the first sliding member 220 by a locking screw.

[0077] By setting the first cutting blade 230 and the first sliding member 220 to be detachably connected, the first cutting blade 230 can be easily disassembled and replaced, so that the first cutting mechanism 200 can be compatible with a variety of different cutting blades, thus expanding the application range of the first cutting mechanism 200.

[0078] To guide the sliding of the first sliding member 220, a molding groove is provided on the molding base 100, and the first sliding member 220 slides along the molding groove.

[0079] In some embodiments of this application, the second cutting mechanism 300 includes: a second power telescopic component 310;

[0080] The second sliding member 320 is slidably connected to the molding base 100 and is connected to the second power telescopic member, and can extend and retract under the drive of the second power telescopic member.

[0081] The second power telescopic component consists of a second cylinder body and a telescopic rod connected to the second cylinder body.

[0082] The second sliding member 320 and the second telescopic rod are connected by a second connecting member. The connection structure of the second connecting member is the same as that of the second sliding member 320 and the second telescopic rod, and will not be described in detail here.

[0083] The second cutter 330 is detachably connected to the second slider 320 and is shaped to fit the first cutter 230 so as to cut off the electronic component pin when in contact with the first cutter 230.

[0084] The second cutting blade 330 is configured to be shaped to match the first cutting blade 230, and the two can quickly cut off the pins of electronic components when in contact with the first cutting blade 230.

[0085] The second cutting blade 330 can be locked to the second sliding member 320 by screws to achieve connection and fixation with the second sliding member 320.

[0086] The lead-cutting mechanism for forming electronic component pins in this embodiment is configured as a first lead-cutting mechanism 200 and a second lead-cutting mechanism 300 that can move relative to each other. When cutting the pins, the first lead-cutting mechanism 200 and the second lead-cutting mechanism 300 move simultaneously toward the pins of the electronic component to cut off the pins. Compared with the method of cutting the pins with the two lead-cutting mechanisms facing each other, the lead-cutting speed is faster and the lead-cutting efficiency is higher.

[0087] Furthermore, the relative movement of the two cutting blades in contact with each other results in a large cutting force and a good cutting effect.

[0088] In some embodiments of this application, the electronic component lead cutting device further includes a lead length adjustment mechanism, which can be used to adjust the length of the leads cut off by the first lead cutting mechanism 200 and the second lead cutting mechanism 300 from the electronic component.

[0089] In some embodiments of this application, the cutting length adjustment mechanism includes:

[0090] Adjustable base 410 is slidably connected to the molded base 100;

[0091] The automatic adjustment component 430 cooperates with the molding base 100 and drives the molding base 100 to slide relative to the adjustment base 410 during operation, so as to change the corresponding position of the first cutting mechanism 200 and the second cutting mechanism 300 with the electronic component pin.

[0092] During adjustment, the automatic adjustment component 430 moves, driving the molding base 100 that cooperates with it to move, that is, to slide linearly relative to the adjustment base 410. When the molding base 100 slides, it will drive the first cutting mechanism 200 and the second cutting mechanism 300 assembled above it to move along the extension direction of the tube pin, thereby changing their corresponding positions with the tube pin and realizing the adjustment of the position of the cut tube pin length to cut out tube pins of different lengths.

[0093] Specifically, during the lead cutting process, the electronic component is conveyed downwards via an inclined conveyor 700. The conveyor 700 adopts an existing structure and has a conveyor trough with an open side. As the electronic component is conveyed downwards along the inclined conveyor 700, the lead extends out from the open side. The first lead cutting mechanism 200 and the second lead cutting mechanism 300 are respectively arranged above and below the conveyor 700. The first lead cutting blade 230 and the second lead cutting blade 330 are arranged perpendicular to the lead. The forming base 100 is arranged perpendicular to the conveyor 700.

[0094] During the cutting process, the first cutting mechanism 200 and the second cutting mechanism 300, which are respectively arranged above and below the conveying device 700 with vertical pins, move towards the pins and cut them off by applying cooperating shearing forces in the direction of the vertical pins.

[0095] When the automatic adjustment component 430 is activated, it drives the molding base 100 to move along the extension direction of the tube pin, thereby causing the first cutting mechanism 200 and the second cutting mechanism 300 to also move along the extension direction of the tube pin, changing their corresponding positions to the tube pin, and thus changing the length of the tube pin that is cut off.

[0096] By cooperating with the automatic adjustment component 430 and the molding base 100, the relative pin positions of the first cutting mechanism 200 and the second cutting mechanism 300 can be adjusted, thereby changing the length of the pins cut off from the electronic components. This eliminates the need for multiple cutting mechanisms, allowing different pin lengths to be cut off with a single cutting mechanism, reducing manufacturing costs and improving the versatility of the entire molding machine.

[0097] In some embodiments of this application, the electronic component lead-cutting device further includes a touch display component, which is at least capable of displaying and inputting the lead length of the electronic component.

[0098] The touch display component is a touch screen, which can adopt an existing touch screen structure. It has touch buttons on the top, and the length of the lead to be cut off of the electronic component can be input by touching the corresponding button. It can also display parameters such as the current lead length of the electronic component.

[0099] The controller communicates with the automatic adjustment component 430 and the touch display component, receives the cutting length of the touch display component, and controls the automatic adjustment component 430 to operate according to the cutting length.

[0100] The controller can transmit signals by communicating with the automatic adjustment component 430 and the touch display component.

[0101] When the user inputs the cutting length via the touch display component, the controller receives the cutting length value and controls the automatic adjustment component 430 to automatically adjust the movement of the molding base 100 relative to the adjustment base 410, thereby achieving automatic adjustment of the cutting length. The entire adjustment process does not require manual operation, making the adjustment more convenient and faster.

[0102] In some embodiments of this application, the cutting length adjustment mechanism includes:

[0103] The fixing base 420 is at least capable of fixing the automatic adjustment assembly 430, and includes:

[0104] The fixed base plate 421 is arranged parallel to the adjustment base 410. The fixed base plate 421 can be a square plate, a circular plate, or a rectangular plate, etc.

[0105] The support member 422 is vertically connected between the fixed base plate 421 and the adjusting base 410, and a receiving space 440 is formed between the fixed base plate 421, the support member 422 and the adjusting base plate.

[0106] The support member 422 is a support rod, and multiple support rods can be provided and arranged around the circumference of the fixed base plate 421.

[0107] During connection, one end of the support rod can be fixed to the fixed base plate 421, and the other end can be screwed to the adjustment base 410.

[0108] In some embodiments of this application, the automatic adjustment component 430 includes:

[0109] The screw component 431 passes through the adjusting base 410 and is threadedly connected to the molding base 100;

[0110] The drive device 432 is assembled onto the fixed base 420 and is connected to the screw component 431 for driving the screw component 431 to rotate.

[0111] The screw component 431 is connected to the drive device 432 and threadedly connected to the molding base 100. When the drive device 432 rotates, since the drive device 432 and the fixed base 420 are fixed, and the screw component 431 is connected to the drive device 432, the screw component 431 will only rotate under the drive of the drive device 432. Since it is threadedly connected to the molding base 100, the rotation of the molding base 100 is limited because the molding base 100 is slidably connected to the adjusting base 410. Therefore, the molding base 100 can only move linearly along the adjusting base 410, thereby changing the position of the first adjusting mechanism and the second adjusting mechanism above it, so as to change the pin cutting length of the electronic component.

[0112] The controller pre-stores the number of rotations of the screw component 431 that matches the corresponding cut length.

[0113] When the screw component 431 rotates one revolution, the forming base 100 moves 1 mm.

[0114] If the input is to cut off a 2mm pin length, the controller will control the drive device 432 to drive the screw component 431 to rotate 2 revolutions.

[0115] If the input is to cut off a 4mm pin length, the controller will control the screw component 431 to rotate four times, so that the molding base 100 can move 4mm relative to the initial position.

[0116] In some embodiments of this application, the automatic adjustment component 430 further includes a limiting structure located within the receiving space 440 and disposed on the screw component 431, for cooperating with the adjustment base 410 to limit the movement of the screw component 431.

[0117] When the drive device 432 drives the screw component 431 to rotate, it will cause the molding base 100 that cooperates with it to move linearly relative to the screw component 431. If the drive device 432 causes the screw component 431 to vibrate during operation, the screw component 431 will move axially, causing the connection between the screw component 431 and the coupling 600 to fail. In order to avoid the axial movement of the screw component 431, which would cause the entire automatic adjustment assembly 430 to malfunction, a limiting structure is set on the adjustment base 410 to limit the screw component 431 axially and avoid the above-mentioned problems.

[0118] In some embodiments of this application, the adjustment base 410 includes a first side 412 near the fixed base plate 421 and a second side 413 near the molded base 100.

[0119] The limiting structure includes:

[0120] A first limiting part 433 is formed on the screw member 431 and is used to limit the movement of the screw member 431 along the first direction by abutting against the first side surface 412 of the adjusting base 410.

[0121] The first direction is the direction of movement toward the molding base 100.

[0122] The first limiting part 433 is assembled to the limiting member on the screw component 431, limiting the movement of the screw component 431 toward the forming base 100. The limiting member is a limiting nut, which is screwed onto the screw component 431.

[0123] The second limiting part 434 is formed on the screw member 431 and is used to limit the movement of the screw member 431 along the second direction by abutting against the second side surface 413 of the adjusting base 410.

[0124] The second direction is the direction of movement toward the fixed substrate 421, which is opposite to the first direction.

[0125] The second limiting part 434 is a limiting protrusion or a limiting fixing member formed on the screw component 431.

[0126] During assembly, the screw can be passed through the adjusting base, with one side abutting against the upper limit of the adjusting base via the second limiting part 434, and the limiting part screwed on the other side to limit it.

[0127] By cooperating with the first limiting part 433 and the second limiting part 434, the axial positioning of the screw component 431 can be achieved, thereby avoiding the problem of connection failure between the screw component 431 and the coupling 600.

[0128] In some embodiments of this application, wear-resistant bearings 500 are provided between the first limiting part 433 and the adjusting base 410, and between the second limiting part 434 and the adjusting base 410. The wear-resistant bearings 500 prevent hard frictional contact between the first limiting part 433 and the second limiting part 434 and the adjusting base 410, reducing wear and friction, and also making the rotation of the screw component 431 smoother.

[0129] In some embodiments of this application, the screw component 431 includes a first screw segment 4311, a second screw segment 4312, a third screw segment 4313, and a fourth screw segment 4314 connected in sequence. The outer diameters of the first screw segment 4311, the second screw segment 4312, the third screw segment 4313, and the fourth screw segment 4314 increase sequentially.

[0130] The first screw section 4311 is inserted into the coupling 600 and connected and fixed to the coupling 600.

[0131] The first limiting part 433 is provided on the second screw section 4312.

[0132] A through hole is made on the adjusting base 410, and the third screw section 4313 is inserted into the through hole.

[0133] The wear-resistant bearing 500 is pressed between the adjusting base 410 and the first limiting part 433 by the first limiting part 433, and the end face of the wear-resistant bearing 500 abuts against the end face of the third screw section 4313 to limit its movement.

[0134] The end face of the fourth screw section 4314 abuts against the second side 413 of the adjusting base 410.

[0135] In some embodiments of this application, the drive device 432 has an output shaft extending into the receiving space 440, and the screw component 431 is disposed in the receiving space 440 and connected to the output shaft via a coupling 600.

[0136] The drive unit 432 is a drive motor, and the output shaft is used to output power to the screw component 431.

[0137] The screw component 431 is built into the housing space 440 and connected to the output shaft via the coupling 600, which realizes a compact arrangement between the screw component 431 and the drive device 432 and reduces the space occupied by the entire automatic adjustment assembly 430.

[0138] In some embodiments of this application, sliding components are provided on the molding base 100 and the adjusting base 410. The sliding components include a sliding rail 411 disposed on one of the molding base 100 and the adjusting base 410 and a sliding groove disposed on the other of the molding base 100 and the adjusting base 410.
