Description

Technical Field

[0002] At present, many different forms of electron tubes are needed in the production process of electronic equipment, such as common diodes and triodes. These electronic components cannot be used directly after production because the components may be used on different circuit boards. Therefore, their pin shapes are not considered before production. They are all uniform long straight pins to ensure that they have sufficient pin length to be bent into a shape that matches the circuit contacts when they need to participate in circuit assembly. In this step, a pin forming machine is required to ensure the forming efficiency of the components.

[0003] However, the existing pin forming machine has the following defects: for example, in order to separate the pins from each other and enter the forming machine one by one, a vibration plate needs to be configured in front of the pin forming machine. The vibration plate will generate a lot of noise when working, which makes the workers in the workshop very uncomfortable. The existing improvement method is to glue and fix their pins side by side and equidistantly on the paper tape when the diodes or transistors are produced, so there is no need to use a vibration plate. Therefore, under the conditions of existing technology, we have made further optimization of the pin forming machine. Summary of the invention

[0043] like Figure 1-20 The pin forming machine shown in the figure includes a conveying unit, a forming unit, a discharge assembly 5 and a monitoring unit 8. The whole device has the functions of feeding, shearing, forming, discharging, recycling and counting. The conveying unit includes a feeding mechanism 1, a conveying tray 2, a recycling mechanism 6 and a conveyor belt 7. Objects that need to be pin-formed are arranged on the conveyor belt 7, which can be diodes, triodes, and electronic components such as capacitors and inductors with pins. The conveyor belt 7 has two parallel flexible belts 720. The two flexible belts 720 are either fixedly connected to the double-sided pin units 711 on the opposite side as the objects that need to be pin-formed, or the objects that need to be pin-formed. The single-sided pin unit 712 is fixedly connected as the object that needs to be pin-formed, and the electronic components with pins are divided into two categories, corresponding to the two working modes of the pin forming machine. The pins of the double-sided pin unit 711 or the single-sided pin unit 712 are arranged equidistantly and parallelly on the side of the flexible belt 720 opposite to the conveyor disc 2. The structural form is similar to the toothed belt and is used to cooperate with the conveyor disc 2 with the same toothed surface structure to achieve high-precision raw material transmission control. The conveyor belt 7 is discharged by the feeding mechanism 1, bypasses the conveyor disc 2 and returns to the recycling mechanism 6. In this process, the objects that need to be pin-formed on the conveyor belt 7 are After being cut off and bypassing the conveyor disc 2, only the flexible belt 720 part of the conveyor belt 7 is wound onto the roller of the recycling mechanism 6, and the pins of the electronic components can be adhered again after recycling, so that the conveyor belt 7 can continue to work on the pin forming machine as a complete conveyor belt 7. The conveyor disc 2 includes an upper disc 201, a lower disc 202 and a driving mechanism 204. The upper disc 201 and the lower disc 202 constitute a double-layer structure parallel to each other. The outer edges of the upper disc 201 and the lower disc 202 are both provided with toothed rings 205. The toothed rings 205 are suitable for meshing with the conveyor belt 7 with pin protrusions to prevent the conveyor disc 2 from driving the conveyor. The conveyor belt 7 slips when it moves, which improves the accuracy of controlling the supply quantity of the processing object. The upper plate 201 and the lower plate 202 are fixedly connected by the main shaft 203. The main shaft 203 drives the upper plate 201 and the lower plate 202 to rotate synchronously. There is a feeding channel 206 between the lower plate 202 and the main shaft 203. The electronic components with formed pins enter the discharge assembly 5 through the feeding channel 206. The main shaft 203 is fixedly connected to the rotating output end of the driving mechanism 204. The driving mechanism 204 has a motor and a reducer. The power output by the motor is transmitted to the main shaft 203 after being decelerated and torque-increased by the reducer.

[0044] The molding unit includes a double-sided molding mechanism 3 and a single-sided molding mechanism 4, which are respectively suitable for processing electronic components with double-sided pins and electronic components with single-sided pins. The double-sided molding mechanism 3 is suitable for cooperating with the conveyor disc 2 to cut off the molding objects with double-sided pins on the conveyor belt 7 and press the pins into a preset shape, such as pressing and cutting spindle-shaped diode pins. The double-sided molding mechanism 3 includes a first sliding mechanism 310, a rotary arm 320 and a double-sided molding assembly 330. The first sliding mechanism 310 has a servo motor, and the rotary arm 320 can rotate in the horizontal direction. The double-sided molding assembly 330 is installed on the first sliding mechanism 310 through the rotary arm 320. The first sliding mechanism 310 is suitable for changing the distance between the double-sided molding assembly 330 and the conveyor disc 2. The swing arm 320 is suitable for changing the angle of the double-sided forming component 330 relative to the conveying disc 2. The first sliding mechanism 310 includes a first guide rail 311, a first slider 312 and a stand 313. The first slider 312 and the first guide rail 311 achieve relative movement through a gear rack structure. The gear can achieve a high position control accuracy under the drive of the servo motor, thereby meeting the demand for fine-tuning the position of the double-sided forming component 330. The realization of fine-tuning the position can effectively ensure the cutting accuracy of electronic components. The first slider 312 can translate smoothly along the first guide rail 311. The double-sided forming component 330 will be in a working state only when the double-sided forming component 330 is close to the conveying disc 2; when the double-sided forming component 330 is away from the conveying disc 2, the double-sided forming The molding component 330 will remain in a silent state, the lower end of the stand 313 is fixedly connected to the upper surface of the first slider 312, and moves with the first slider 312. The stand 313 is rotatably connected with a cutting roller 314. When the cutting roller 314 is tightly fitted with the conveying disc 2, it will rotate with the conveying disc 2, thereby cutting off the pins between the two. The axis of the cutting roller 314 is parallel to the axis of the conveying disc 2, and both can rotate in the horizontal direction. The double-sided molding component 330 is located at the middle height of the cutting roller 314. Because the lengths of the symmetrical pins on both sides of the vast majority of electronic components with double-sided pins are the same, the double-sided molding component 330 is located in a symmetrical position, which can well ensure that the lengths of the symmetrical side pins formed after cutting are the same. The rotary arm 320 includes a turntable 321 and a cantilever 322. The cantilever 322 can rotate around the axis of the cutting roller 314 under the driving action of the turntable 321. The top turntable 321 of the turntable 321 rotates synchronously with the cantilever 322. The double-sided forming component 330 is fixed to the upper end of the cantilever 322. The double-sided forming component 33 can adjust the direction within a certain angle range following the cantilever 322, and is used to cut off the pins of the forming object with double-sided pins on the conveyor belt 7 and press them into a preset shape. Generally, the pins on one side are only bent once, so that it is easier to contact with the contacts on the circuit board for welding. The double-sided forming component 330 includes a double-sided fixed clamp 331 and a double-sided movable clamp 332. The two can be close to each other to press the pins of the electronic components into a specific shape.The double-sided fixed clamping plate 331 is fixed to the upper end of the swing arm 320 to ensure the installation stability of the double-sided forming assembly 330. The side of the double-sided movable clamping plate 332 is provided with a baffle 334 to block the electronic components gradually approaching on the conveyor belt 7. A pressure sensor 802 can also be added to the baffle 334. When under pressure, it will be determined that the electronic components have entered the processing station. The clamping action of the double-sided forming assembly 330 completes the extrusion forming action. The baffle 334 is provided with a fan 336 on the side away from the double-sided movable clamping plate 332. After the pins are pressed and formed, the clamping plates of the double-sided forming assembly 330 are separated from each other to release the electronic components. The fan 336 can be started to blow the formed electronic components out of the forming grooves between the clamping plates. The double-sided fixed clamping plate 331 is fixedly connected with a first telescopic rod 335, and the movable end of the first telescopic rod 335 is fixedly connected to the baffle 334 The first telescopic rod 335 is a small hydraulic rod, which is used to drive the double-sided movable clamping plate 332 to move relative to the double-sided fixed clamping plate 331 to achieve squeezing and releasing actions. The side of the double-sided fixed clamping plate 331 is provided with a guide groove 333, which is suitable for receiving the baffle 334. The formation of a matching structure can improve the movement stability of the double-sided movable clamping plate 332 relative to the double-sided fixed clamping plate 331. When the double-sided molding assembly 330 is in a silent state, the two clamping plates can fit more closely to reduce unnecessary shaking. The double-sided fixed clamping plate 331 and the double-sided movable clamping plate 332 are provided with double-sided limiting cavities 337 on the opposite sides, and double-sided molding grooves 338 are provided at both ends of the double-sided limiting cavities 337. The double-sided limiting cavities 337 are used to constrain the electronic component body with double-sided pins, and the double-sided molding grooves 338 are used to bend the pins of the electronic components into corresponding specific shapes.

[0045] The single-sided forming mechanism 4 is suitable for cooperating with the conveyor disc 2 to cut off the forming object with single-sided pins on the conveyor belt 7 and press the pins into a preset shape. The single-sided forming mechanism 4 includes a second sliding mechanism, a lifting adjustment mechanism, a spacing adjustment mechanism 410 and two upper and lower symmetrical single-sided forming components 420, which can simultaneously process electronic components with single-sided pins on the upper and lower sides. The spacing adjustment mechanism 410 is used to adjust the distance between the two single-sided forming components 420. Since the distance between the main body of the electronic component with single-sided pins fixed on the flexible belt 720 and the flexible belt 720 may be different, it is very necessary to configure the symmetrical single-sided forming components 420 on the spacing adjustment mechanism 410. The lifting adjustment mechanism is used to adjust the distance between the two The height of the symmetry plane of the single-sided molding component 420, the center of gravity of the symmetrical single-sided molding component 420 is located on the symmetry plane, the lifting and lowering adjustment mechanism is to adjust the height of the center of gravity of the single-sided molding component 420 to better match the height of the center of gravity of the conveyor belt 7, the second sliding mechanism is used to adjust the distance of the single-sided molding component 420 relative to the conveyor disc 2, on the one hand, the electronic components with single-sided pins can be aligned with the single-sided molding component 420 by fine-tuning; on the other hand, the single-sided molding component 420 can be put into a working ready state or a silent state by long-distance movement, the second sliding mechanism includes a second guide rail 401 and a second slider 402, the second slider 402 can be translated along the second guide rail 401, and the same gear rack motion structure is used in the servo Driven by the motor, high-precision position control is achieved. The lifting and adjusting mechanism includes a lifting rod 403 and an electric telescopic rod 404 fixed on the second slider 402. The lifting rod 403 remains parallel to the electric telescopic rod 404. The lifting rod 403 does not have an active telescopic function and is only used to maintain the stability of the up and down movement. The electric telescopic rod 404 will move up and down with the lifting rod 403. The spacing adjustment mechanism 410 is fixedly connected to the movable ends of the lifting rod 403 and the electric telescopic rod 404, so the height of the spacing adjustment mechanism 410 can be changed within a certain range. The upper and lower movable ends of the bidirectional telescopic rod on the spacing adjustment mechanism 410 are respectively fixedly connected to the two single-sided molding components 420. The two movable ends of the bidirectional telescopic rod The ends are set to extend or retract synchronously to ensure that the symmetric planes of the two single-sided forming components 420 remain unchanged relative to the spacing adjustment mechanism 410, reducing the difficulty of motion control of the single-sided forming mechanism 4. The single-sided forming component 420 is used to cut off the pins of the forming object with single-sided pins on the conveyor belt 7 and press them into a specific shape. For example, the three pins of the transistor on the same side are bent into a shape that can correspond to the three contacts of the circuit board to facilitate contact welding. The single-sided forming component 420 includes a single-sided fixed clamping plate 421, a single-sided movable clamping plate 422 and a flip plate 426. The two clamping plates are used to bend the pins on the electronic components into a specific shape. The flip plate 426 has two states. In the vertical state, it is used to constrain the main body of the electronic component to remain vertical;When flipping from a vertical state to a horizontal state, the constraint on the main body of the electronic component is released, which facilitates the electronic component to pop out from the single-sided molding component 420. The single-sided fixed clamping plate 421 is fixedly connected to the movable end of the bidirectional telescopic rod to ensure the stability of the entire single-sided molding component 420. The single-sided fixed clamping plate 421 is fixedly connected to the second telescopic rod 424, and the movable end of the second telescopic rod 424 is fixedly connected to the single-sided movable clamping plate 422. Similarly, the second telescopic rod 424 adopts a micro hydraulic rod to drive the single-sided movable clamping plate 422 to move relative to the single-sided fixed clamping plate 421 to achieve squeezing and releasing actions. The single-sided fixed clamping plate 421 is still provided with an ejection The movable end of the ejector 423 passes through the single-sided fixed clamping plate 421 and points to the single-sided movable clamping plate 422. The ejector 423 is a gas spring for ejecting the formed electronic components from the single-sided movable clamping plate 422. The flip plate 426 is movably connected to the single-sided fixed clamping plate 421 through a rotating structure on the side. The flip plate 426 can rotate within a certain angle range relative to the single-sided fixed clamping plate 421. The single-sided fixed clamping plate 421 is rotatably connected to a swing arm 427 at the back side close to the rotating structure through a hinge structure. The lower end of the swing arm 427 is fixedly connected to a flip driving rod 425. The flip driving rod 425 adopts a small cylinder. The flip plate 426 is close to the rotating structure. The side of the structure is fixedly connected to the movable end of the flip drive rod 425 through a hinge structure to form a simple rocker mechanism. The flip drive rod 425 drives the flip plate 426 to rotate by its own extension and contraction. The single-sided movable clamping plate 422 is provided with a groove that can cooperate with the flip plate 426. The groove is suitable for clamping a molding object with a single-sided pin. When the flip plate 426 is in a vertical state and the single-sided movable clamping plate 422 is away from the single-sided fixed clamping plate 421, the flip plate 426 is embedded in the groove of the single-sided movable clamping plate 422, and the two objects are flush with one side of the single-sided fixed clamping plate 421; when the electronic components enter the single-sided molding assembly 420, the single-sided movable clamping plate 422 moves toward the single-sided fixed clamping plate When the plate 421 approaches, the single-sided movable clamping plate 422 will frame the electronic components of the same shape through the groove to achieve fixation. The single-sided fixed clamping plate 421 has a convex mold 428 on the side opposite to the single-sided movable clamping plate 422, and the single-sided movable clamping plate 422 has a concave mold 429 on the side opposite to the single-sided fixed clamping plate 421. The convex mold 428 and the concave mold 429 cooperate to form a mold cavity for the pins. After the electronic components are framed by the single-sided movable clamping plate 422, the single-sided movable clamping plate 422 continues to approach the single-sided fixed clamping plate 421, so that the mold cavity component formed between the convex mold 428 and the concave mold 429 becomes smaller, thereby squeezing and bending the pins of the electronic components therein into a shape consistent with the mold cavity. ;

[0046] The discharge assembly 5 is located below the conveyor tray 2, and is used to receive the finished electronic components that fall from the conveyor tray 2. The conveyor tray 2 has an upper and lower two-layer structure, which is used to support the flexible belt 720 in an arc shape. The object after pin molding passes between the upper and lower two-layer structure of the conveyor tray 2 and enters the discharge assembly 5, which is used to collect the finished products. The discharge assembly 5 includes a discharge ramp 501 and a storage box 503. The discharge ramp 501 is provided with an axial hole 502 that passes through the upper and lower parts. The axial hole 502 is suitable for the main shaft 203 to pass through and form a rotating pair to avoid the discharge ramp 501 from interfering with the movement of the main shaft 203, and at the same time ensure that all finished electronic components discharged from the lower plate 202 can be received by the discharge ramp 501. The storage box 503 is located below the discharge port of the discharge ramp 501, and is used to receive the finished electronic components discharged from the discharge ramp 501. The storage box 503 is not connected to the entire molding machine, so it is very convenient to replace.

[0047] The monitoring unit 8 is used to record the number of objects remaining on the conveyor belt 7 that need to be pin-formed. The monitoring unit 8 needs to cooperate with the number of rotation circles and angles of the conveyor disc 2 to record the number of objects to be pin-formed. The monitoring unit 8 includes a configuration frame 801 and a sensor 802 installed on the configuration frame 801. The sensor 802 faces the conveyor disc 2. The sensor 802 is composed of an infrared transmitter and an infrared receiver. The number of electronic components that do not participate in pin cutting and forming is recorded by using the principle that infrared rays are reflected and sensed when electronic components approach the sensor 802. The number of electronic components used on the conveyor belt 7 corresponding to the number of rotation circles and angles of the conveyor disc 2 can be used to confirm the number of finished components produced. The configuration frame 801 is also fixedly connected to a suspension 803, and the discharge inclined plate 501 is connected to the suspension 803, which is used to fix the discharge inclined plate 501 to the frame of the equipment.

[0048] The working principle of the pin forming machine is as follows: when the electronic components with double-sided pins are arranged on the conveyor belt 7, the double-sided forming mechanism 3 approaches the conveyor tray 2, and the double-sided forming assembly 330 enters the working state, while the single-sided forming mechanism 4 moves away from the conveyor tray 2, and the single-sided forming assembly 420 enters the silent state. The electronic components with double-sided pins follow the flexible belt 720 and continue to approach the double-sided forming assembly 330. When entering between the double-sided fixed clamping plates 331 and the double-sided movable clamping plates 332, the two clamping plates will immediately approach each other, and the pins connected to the flexible belt 720 are pressed by the upper and lower sharp edges of the clamping plates. The length of the pins at both ends of the electronic component with double-sided pins will be determined, and then as the two clamps continue to approach, the pins of the determined length will be bent and finally formed into the same shape as the double-sided forming groove 338. At the same time, the double-layer forming assembly 330 is driven by the rotary arm 320, and the electronic components originally entering the entrance of the double-sided forming assembly 330 turn to the conveyor plate 2, and then the two clamps move away, and the fan 336 is started to blow the formed components between the two clamps onto the lower plate 202, and enter through the unloading channel 206 and fall into the discharge assembly 5; when the conveyor belt 7 is equipped with a single-sided When the electronic component with pins on one side is moved, the single-sided molding mechanism 4 approaches the conveying tray 2, and the single-sided molding assembly 420 enters the working state, while the double-sided molding mechanism 3 moves away from the conveying tray 2, and the double-sided molding assembly 330 enters the silent state. The electronic component with pins on one side follows the flexible belt 720 and keeps approaching the single-sided molding assembly 420. When it enters between the single-sided fixed clamping plate 421 and the single-sided movable clamping plate 422, the two clamping plates will immediately approach each other, and the pins connected to the flexible belt 720 will be broken by the sharp edge of the clamping plate. The number of multiple pins on one side of the electronic component with pins on one side will be determined, and then As the two clamps continue to approach, the main body of the electronic component will be completely embedded in the groove of the single-sided movable clamp 422, and the pins of a certain length will be bent and finally form the same shape as the cavity formed by the punch 428 and the die 429. After the two clamps are completely pressed together, they will be separated. At the same time, the flip plate 426 rotates rapidly under the drive of the flip drive rod 425 to release the vertical constraint on the main body of the electronic component. Then the ejector 423 is activated to eject the formed component from the through groove of the single-sided movable clamp 422 and drop it onto the lower plate 202, and then fall into the discharge assembly 5 through the discharge channel 206.After the electronic components are cut off, only two parallel flexible belts 720 are left on the conveyor belt 7, which will be rolled up by the rollers on the recycling mechanism 6. Of course, due to errors in the control system, some electronic components that have not been cut off may remain on the flexible belt 720. These residual electronic components will be detected by the sensor 802 of the monitoring unit 8. Combined with the number of rotations and angle data of the conveyor disc 2, the final number of molded products can be calculated after a processing cycle is completed. Since the probability of residual electronic components on the flexible belt 720 is very small, it has almost no effect on the overall number. It is only a guarantee function. When an equipment error occurs, a large number of residual electronic components may be generated, which will trigger the alarm system to remind the staff to repair it in time.
