Description

Technical Field

[0001] This invention relates to the field of pin cutting technology, specifically to a pin cutting device for processing optoelectronic devices and its usage method. Background Technology

[0002] Electronic components are the foundation of electronic products. Commonly used electronic components include resistors, capacitors, inductors, and potentiometers. Pins, also called leads, are the connections from the internal circuitry of an integrated circuit chip to external circuitry; all the pins constitute the chip's interface. The end of the lead is soldered to a pad on the printed circuit board to form a solder joint. After manufacturing, the pins of electronic components need to be trimmed.

[0003] Existing devices typically use conveyor belts to transport electronic components and cut them during the transport process. However, when cutting two-pin electronic components, the components may wobble slightly on the conveyor belt, affecting the cutting effect. Summary of the Invention

[0004] The purpose of this invention is to provide a pin cutting device for processing optoelectronic devices and a method for using the same, so as to solve the problems mentioned in the background art.

It also includes a conveying and cutting mechanism, comprising a rotating shaft, a rotating rod, discs, reciprocating lead screws, a conveyor belt, and a cutting assembly for cutting two-pin electronic components. One end of the rotating shaft is fixedly connected to the output end of the motor. The outer walls of both ends of the rotating rod pass through the concave stage and are rotatably connected to the inner wall of the concave stage. Four discs are provided; the inner walls of two discs are fixedly connected to both ends of the rotating shaft, and the inner walls of the other two discs are fixedly connected to both ends of the rotating rod. Four reciprocating lead screws are provided; one end of each reciprocating lead screw is fixedly connected to the side wall of the disc, and the inner wall of the conveyor belt is rotatably connected to the outer wall of the disc.

[0006] Furthermore, the cutting assembly includes a threaded plate threaded to the outer wall of one end of the reciprocating lead screw, and limit rods fixedly connected to both ends of one side of the inner wall of the concave platform. One end of the limit rod passes through the threaded plate and is slidably connected to the inner wall of the threaded plate. A cutting blade is fixedly connected to one side wall of the threaded plate.

[0007] Furthermore, the sidewall of the threaded plate is provided with a stabilizing component, which includes a rotating plate rotatably connected to the side of the threaded plate near the cutting blade, and four rotating plates are provided.

[0008] Furthermore, a concave shell is rotatably connected to the end of the rotating plate away from the threaded plate. Two concave shells are provided. An inverted T-plate is fixedly connected to the bottom of the concave shell. Sliding bracket rods are respectively connected through and slidably to the top two sides of the inverted T-plate. Springs are respectively fixedly connected to the bottom two sides of the inverted T-plate.

[0009] Furthermore, the bottom of the spring is fixedly connected to the top of the bottom end of the sliding frame rod, and a roller is rotatably connected to one side of the inner wall of the bottom end of the sliding frame rod. The bottom of the outer wall of the roller contacts the bottom of the inner wall of the conveyor belt.

[0010] Furthermore, a pneumatic assembly is provided at the top of the sliding frame rod. The pneumatic assembly includes a piston plate fixedly connected to the top of the sliding frame rod. A fixed shell is slidably connected to the outer wall of the piston plate. The bottom of the fixed shell is fixedly connected to the top side of the inverted T-plate. A bent pipe is connected to one side of the outer wall of the fixed shell.

[0011] Furthermore, auxiliary components are provided at both ends of the inverted T-plate. The auxiliary components include bent rods fixedly connected to both ends of the inverted T-plate, with the outer wall of one end of the bent rod slidably connected to the inner wall of the square hole.

[0012] Furthermore, a connecting plate is fixedly connected to the top of the bent rod, and one connecting plate is provided. A sliding rod is slidably connected through the top of the connecting plate, and an extrusion shell is fixedly connected to the bottom of the sliding rod.

[0013] Furthermore, a return spring is fixedly connected to the top of the extrusion shell, and the top of the return spring is fixedly connected to the bottom of the connecting plate. A silicone belt is rotatably connected to one side of the inner wall of the extrusion shell.

[0014] A method for using a pin trimming device for processing optoelectronic devices includes the following steps: Step 1: Cut the two-pin electronic components. Place the tops of multiple two-pin electronic components between the tops of the outer walls of two conveyor belts, so that the two pins of the two-pin electronic components are at the bottom. Start the motor. The motor drives the rotating shaft to rotate, the rotating shaft drives the disc to rotate, and the disc drives the conveyor belt to rotate. During the rotation of the conveyor belt, the two-pin electronic components can be transported. During this process, the disc drives the reciprocating screw to rotate. It is limited by the limit rod. The reciprocating screw drives the threaded plate to slide along the outer wall of the limit rod. The threaded plate drives the cutting blade to move. The two cutting blades move closer to each other, thereby cutting the two pins of the two-pin electronic components. Step 2: Improve transportation stability. As the two threaded plates approach each other, the threaded plates drive the rotating plates to move. During the approach of the two rotating plates, due to the concave shell, the squeezing force generated by the two rotating plates causes the concave shell to descend vertically. The concave shell drives the inverted T-plate to descend, the inverted T-plate drives the sliding frame rod to descend, and the sliding frame rod drives the roller to descend. During the descent of the roller, the conveyor belt can be further squeezed, which increases the tension of the conveyor belt. Step 3: Air jetting is applied to the cutting blade. When the sliding rod comes into contact with the conveyor belt, it is subjected to the reaction force of the conveyor belt, causing the sliding rod to move upward. The sliding rod drives the piston plate to slide into the interior of the fixed shell, allowing the airflow inside the fixed shell to enter the interior of the curved tube. The airflow is then jetted through the curved tube towards the two-pin electronic components in the cutting process. The force generated can spray the pins adhering to the cutting blade. Step 4: Improve the cutting accuracy of the cutting blade. When the inverted T-plate descends, it drives the bent rod to descend, which in turn drives the connecting plate to descend. The connecting plate then drives the sliding rod to descend, which in turn drives the extrusion shell to descend. The extrusion shell then drives the silicone belt to descend. During the descent, the silicone belt will contact the tops of multiple two-pin electronic components, preventing the two-pin electronic components from shaking during transportation. This also improves the cutting accuracy of the cutting blade on the pins of the two-pin electronic components.

[0015] The present invention has the following beneficial effects: 1. This invention places the tops of multiple two-pin electronic components between the tops of the outer walls of two conveyor belts, so that the two pins of the two-pin electronic components are positioned below. The motor is started, driving a rotating shaft to rotate, which in turn drives a disc to rotate. The disc drives the conveyor belt to rotate, transporting the two-pin electronic components. During this process, the disc drives a reciprocating screw to rotate, which is limited by a limiting rod. The reciprocating screw drives a threaded plate to slide along the outer wall of the limiting rod. The threaded plate drives a cutting blade to move, bringing the two cutting blades closer together to cut the two pins of the two-pin electronic components. At this time, due to the elastic deformation of a spring, the spring causes a sliding frame rod to descend vertically along the inner wall of an inverted T-plate. The sliding frame rod drives a roller to descend, and the roller's descent compresses the bottom of the conveyor belt, increasing the belt tension and improving the stability of the conveyor belt's transport of the two-pin electronic components, as well as the stability of cutting the two pins.

[0016] (2) In this invention, when the two threaded plates approach each other, the threaded plates drive the rotating plates to move. When the two rotating plates approach each other, they are subjected to the setting of the concave shell. The squeezing force generated by the two rotating plates causes the concave shell to descend vertically. The concave shell drives the inverted T plate to descend. The inverted T plate drives the sliding frame rod to descend. The sliding frame rod drives the roller to descend. During the descent of the roller, it can further squeeze the conveyor belt, which increases the tension of the conveyor belt. Moreover, due to the setting of the roller, when the roller squeezes the conveyor belt excessively, the roller will roll along the bottom of the inner wall of the conveyor belt to prevent the roller from affecting the conveyor belt's transport effect on the dual-pin electronic components, thereby improving the running stability of the conveyor belt.

[0017] (3) In this invention, when the sliding frame rod comes into contact with the conveyor belt, it is subjected to the reaction force of the conveyor belt, causing the sliding frame rod to move upward. The sliding frame rod drives the piston plate to slide into the interior of the fixed shell, so that the airflow inside the fixed shell enters the interior of the curved tube. The airflow is sprayed through the curved tube to the two-pin electronic components in the cutting process. The force generated can spray the pins adhering to the cutting knife, preventing the cut pins from adhering to the blade of the cutting knife, thereby improving the cutting effect of the cutting knife on the subsequent two-pin electronic components.

[0018] (4) In this invention, when the inverted T-plate descends, the inverted T-plate drives the bent rod to descend, the bent rod drives the connecting plate to descend, the connecting plate drives the sliding rod to descend, the sliding rod drives the extrusion shell to descend, and the extrusion shell drives the silicone belt to descend. During the descent of the silicone belt, it will contact the top of multiple two-pin electronic components to prevent the two-pin electronic components from shaking during transportation. This improves the cutting accuracy of the cutting blade on the pins of the two-pin electronic components and further improves the cutting effect of the two-pin electronic components. When the silicone belt contacts the top of multiple two-pin electronic components, because the silicone belt is made of silicone, it has low friction, high temperature resistance and high wear resistance, and is suitable for applications that require reduced friction and stable operation. This will prevent the transportation effect of the two-pin electronic components from being affected.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1, please refer to Figure 1 - Figure 8As shown, the present invention is a pin cutting device for processing optoelectronic devices and its usage method, including a base plate 1, a concave stage 2 fixedly connected to the top of the base plate 1, a motor 3 fixedly connected to one side of the outer wall of the concave stage 2, and square holes 4 respectively opened on both sides of the concave stage 2, and also includes; The conveying and cutting mechanism 5 includes a rotating shaft 51, a rotating rod 52, a disc 53, a reciprocating screw 54, and a conveyor belt 59. The tops of multiple two-pin electronic components are placed between the tops of the outer walls of the two conveyor belts 59, so that the two pins of the two-pin electronic components are located below. The motor 3 is started, and the motor 3 drives the rotating shaft 51 to rotate. The rotating shaft 51 drives the disc 53 to rotate, and the disc 53 drives the conveyor belt 59 to rotate. During the rotation of the conveyor belt 59, the two-pin electronic components can be conveyed. The cutting component 55 is used to cut the two-pin electronic components. One end of the rotating shaft 51 is fixedly connected to the output end of the motor 3. The outer walls of both ends of the rotating rod 52 pass through the concave platform 2 and are rotatably connected to the inner wall of the concave platform 2. Four discs 53 are provided. The inner walls of two discs 53 are fixedly connected to the two ends of the rotating shaft 51, and the inner walls of the other two discs 53 are fixedly connected to the two ends of the rotating rod 52. Four reciprocating screws 54 are provided. One end of the reciprocating screw 54 is fixedly connected to the side wall of the disc 53. The inner wall of the conveyor belt 59 is rotatably connected to the outer wall of the disc 53.

[0025] The cutting assembly 55 includes a threaded plate 551 that is threaded to the outer wall of one end of the reciprocating lead screw 54. Limiting rods 552 are fixedly connected to both ends of one side of the inner wall of the concave platform 2. One end of the limiting rod 552 passes through the threaded plate 551 and is slidably connected to the inner wall of the threaded plate 551. A cutting blade 553 is fixedly connected to one side wall of the threaded plate 551.

[0026] The side wall of the threaded plate 551 is provided with a stabilizing component 56. Due to the setting of the roller 566, when the roller 566 excessively squeezes the conveyor belt 59, the roller 566 will roll along the bottom of the inner wall of the conveyor belt 59 to prevent the roller 566 from affecting the conveyor belt 59's transport effect on the two-pin electronic components. This improves the running stability of the conveyor belt 59. The stabilizing component 56 includes a rotating plate 561 rotatably connected to the side of the threaded plate 551 near the cutter 553. There are four rotating plates 561.

[0027] A concave shell 562 is rotatably connected to the end of the rotating plate 561 away from the threaded plate 551. There are two concave shells 562. An inverted T-plate 563 is fixedly connected to the bottom of the concave shell 562. Sliding bracket rods 564 are respectively connected through and slidably to the top two sides of the inverted T-plate 563. Springs 565 are respectively fixedly connected to the bottom two sides of the inverted T-plate 563.

[0028] The bottom of spring 565 is fixedly connected to the top of the bottom of sliding frame rod 564. Roller 566 is rotatably connected to one side of the inner wall of the bottom of sliding frame rod 564. The bottom of the outer wall of roller 566 contacts the bottom of the inner wall of conveyor belt 59. Under the elastic deformation of spring 565, spring 565 causes sliding frame rod 564 to move vertically downward along the inner wall of inverted T plate 563. Sliding frame rod 564 drives roller 566 to move downward. During the downward movement, roller 566 can squeeze the bottom of conveyor belt 59, thereby increasing the tension of conveyor belt 59. This improves the stability of conveyor belt 59 in transporting dual-pin electronic components and the stability of cutting dual-pin electronic components.

[0029] In Example 2, a pneumatic assembly 57 is provided at the top of the sliding rod 564. When the sliding rod 564 comes into contact with the conveyor belt 59, it is subjected to the reaction force of the conveyor belt 59, causing the sliding rod 564 to move upward. The sliding rod 564 drives the piston plate 572 to slide into the fixed shell 571, allowing the airflow inside the fixed shell 571 to enter the bent pipe 573. The airflow is then sprayed through the bent pipe 573 towards the two-pin electronic components during the cutting process, generating a force that can... Spraying the pins adhering to the cutting blade 553 prevents the cut pins from adhering to the blade of the cutting blade 553, thereby improving the cutting effect of the cutting blade 553 on subsequent two-pin electronic components. The pneumatic assembly 57 includes a piston plate 572 fixedly connected to the top of the sliding frame rod 564. A fixing shell 571 is slidably connected to the outer wall of the piston plate 572. The bottom of the fixing shell 571 is fixedly connected to the top side of the inverted T plate 563. A bent pipe 573 is connected to one side of the outer wall of the fixing shell 571.

[0030] The inverted T-plate 563 is provided with auxiliary components 58 at both ends. The auxiliary components 58 include bent rods 581 fixedly connected to both ends of the inverted T-plate 563. One end of the bent rod 581 is slidably connected to the inner wall of the square hole 4.

[0031] A connecting plate 582 is fixedly connected to the top of the bent rod 581. There is one connecting plate 582. A sliding rod 583 is slidably connected through the top of the connecting plate 582. An extrusion shell 584 is fixedly connected to the bottom of the sliding rod 583.

[0032] A return spring 585 is fixedly connected to the top of the extrusion shell 584. The top of the return spring 585 is fixedly connected to the bottom of the connecting plate 582. A silicone belt 586 is rotatably connected to one side of the inner wall of the extrusion shell 584. When the silicone belt 586 comes into contact with the top of multiple two-pin electronic components, because the silicone belt 586 is made of silicone, it has low friction, high temperature resistance and high wear resistance. It is suitable for applications that require reduced friction and stable operation, and will not affect the transportation effect of the two-pin electronic components.

[0033] A method for using a pin trimming device for processing optoelectronic devices includes the following steps: Step 1: Cut the two-pin electronic components. Place the tops of multiple two-pin electronic components between the tops of the outer walls of the two conveyor belts 59, so that the two pins of the two-pin electronic components are located below. Start the motor 3. The motor 3 drives the rotating shaft 51 to rotate. The rotating shaft 51 drives the disc 53 to rotate. The disc 53 drives the conveyor belt 59 to rotate. During the rotation of the conveyor belt 59, the two-pin electronic components can be transported. During this process, the disc 53 drives the reciprocating screw 54 to rotate. It is limited by the limit rod 552. The reciprocating screw 54 drives the threaded plate 551 to slide along the outer wall of the limit rod 552. The threaded plate 551 drives the cutting blade 553 to move. The two cutting blades 553 move closer to each other, thereby cutting the two pins of the two-pin electronic components. Step 2: Improve transportation stability. As the two threaded plates 551 approach each other, the threaded plates 551 drive the rotating plate 561 to move. During the approach of the two rotating plates 561, due to the setting of the concave shell 562, the squeezing force generated by the two rotating plates 561 causes the concave shell 562 to descend vertically. The concave shell 562 drives the inverted T plate 563 to descend. The inverted T plate 563 drives the sliding frame rod 564 to descend. The sliding frame rod 564 drives the roller 566 to descend. During the descent of the roller 566, it can further squeeze the conveyor belt 59, thereby increasing the tension of the conveyor belt 59. Step 3: Air is sprayed onto the cutting blade 553. When the sliding rod 564 comes into contact with the conveyor belt 59, it is subjected to the reaction force of the conveyor belt 59, causing the sliding rod 564 to move upward. The sliding rod 564 drives the piston plate 572 to slide into the fixed shell 571, so that the airflow inside the fixed shell 571 enters the inside of the bent tube 573. The airflow is sprayed through the bent tube 573 towards the two-pin electronic components in the cutting process. The force generated can spray the pins adhering to the cutting blade 553. Step 4: Improve the cutting accuracy of the cutting blade 553. When the inverted T-plate 563 descends, it drives the bent rod 581 to descend, which in turn drives the connecting plate 582 to descend. The connecting plate 582 drives the sliding rod 583 to descend, which in turn drives the extrusion shell 584 to descend. The extrusion shell 584 then drives the silicone belt 586 to descend. During the descent, the silicone belt 586 will contact the tops of multiple two-pin electronic components, preventing the two-pin electronic components from shaking during transportation. This improves the cutting accuracy of the cutting blade 553 on the pins of the two-pin electronic components.

[0034] In use, the tops of multiple two-pin electronic components are placed between the tops of the outer walls of the two conveyor belts 59, so that the two pins of the two-pin electronic components are positioned downwards. The motor 3 is started, and the motor 3 drives the rotating shaft 51 to rotate. The rotating shaft 51 drives the disc 53 to rotate, and the disc 53 drives the conveyor belts 59 to rotate. During the rotation of the conveyor belts 59, the two-pin electronic components are transported. During this process, the disc 53 drives the reciprocating screw 54 to rotate, which is limited by the limit rod 552. The reciprocating screw 54 drives the threaded plate 551 to slide along the outer wall of the limit rod 552. 1. The cutting blade 553 is moved, and the two cutting blades 553 move closer to each other to cut the two leads of the two-lead electronic component. At this time, due to the elastic deformation of the spring 565, the spring 565 causes the sliding frame rod 564 to move vertically downward along the inner wall of the inverted T plate 563. The sliding frame rod 564 drives the roller 566 to move downward. During the descent, the roller 566 can squeeze the bottom of the conveyor belt 59, thereby increasing the tension of the conveyor belt 59 and improving the stability of the conveyor belt 59 in transporting the two-lead electronic component, thus improving the stability of cutting the two leads of the two-lead electronic component.

[0035] As the two threaded plates 551 approach each other, the threaded plates 551 drive the rotating plate 561 to move. During this process, the two rotating plates 561, under the influence of the concave shell 562, exert pressure on the concave shell 562, causing it to descend vertically. The concave shell 562 then drives the inverted T-plate 563 to descend, which in turn drives the sliding frame rod 564 to descend. The sliding frame rod 564 then drives the roller 566 to descend. As the roller 566 descends, it further compresses the conveyor belt 59, increasing its tension. Furthermore, due to the roller 566's design, when it excessively compresses the conveyor belt 59, it rolls along the bottom of the inner wall of the conveyor belt 59, preventing it from affecting the transport of the dual-pin electronic components and thus improving the operational stability of the conveyor belt 59.

[0036] When the sliding rod 564 comes into contact with the conveyor belt 59, it is subjected to the reaction force of the conveyor belt 59, causing the sliding rod 564 to move upward. The sliding rod 564 drives the piston plate 572 to slide into the fixed shell 571, allowing the airflow inside the fixed shell 571 to enter the curved tube 573. The airflow is then sprayed through the curved tube 573 towards the two-pin electronic components during the cutting process. The force generated can spray the pins adhering to the cutting blade 553, preventing the cut pins from adhering to the blade of the cutting blade 553, thereby improving the cutting effect of the cutting blade 553 on the subsequent two-pin electronic components.

[0037] When the inverted T-plate 563 descends, it drives the bent rod 581 to descend, which in turn drives the connecting plate 582 to descend. The connecting plate 582 then drives the sliding rod 583 to descend, which in turn drives the extrusion shell 584 to descend. The extrusion shell 584 then drives the silicone belt 586 to descend. During its descent, the silicone belt 586 contacts the tops of multiple two-pin electronic components, preventing them from shaking during transport. This also improves the cutting accuracy of the cutting blade 553 on the pins of the two-pin electronic components, further enhancing the cutting effect. When the silicone belt 586 contacts the tops of multiple two-pin electronic components, its low friction, high temperature resistance, and high wear resistance make it suitable for applications requiring reduced friction and stable operation, thus preventing any impact on the transport of the two-pin electronic components.

10. A method for using a lead cutting device for processing optoelectronic devices, using the lead cutting device for processing optoelectronic devices as claimed in claim 9, characterized in that: The following steps are included: Step 1: cutting the double-pin electronic components, placing the top ends of a plurality of double-pin electronic components between the top ends of the outer walls of two conveyor belts (59), so that the double pins of the double-pin electronic components are located at the bottom, starting the motor (3), the motor (3) drives the rotating shaft (51) to rotate, the rotating shaft (51) drives the disc (53) to rotate, the disc (53) drives the conveyor belt (59) to rotate, and the double-pin electronic components can be conveyed during the rotation of the conveyor belt (59). During this process, the disc (53) drives the reciprocating screw rod (54) to rotate, and is limited by the limiting rod (552). The reciprocating screw rod (54) drives the threaded plate (551) to slide along the outer wall of the limiting rod (552), and the threaded plate (551) drives the cutting knife (553) to move, and the two cutting knives (553) approach each other, thereby cutting the double pins of the double-pin electronic components; Step 2: improving transportation stability. When the two threaded plates (551) approach each other, the threaded plates (551) drive the rotating plates (561) to move. When the two rotating plates (561) approach each other, the concave shell (562) is set. The extrusion force generated by the two rotating plates (561) causes the concave shell (562) to vertically descend. The concave shell (562) drives the inverted T-plate (563) to descend. The inverted T-plate (563) drives the sliding frame rod (564) to descend. The sliding frame rod (564) drives the roller (566) to descend. When the roller (566) descends, it can further squeeze the conveyor belt (59), thereby increasing the tension of the conveyor belt (59). Step 3: Jetting the cutting blade (553). When the sliding rod (564) contacts the conveyor belt (59), the sliding rod (564) is subjected to the reaction force of the conveyor belt (59), so that the sliding rod (564) moves upward. The sliding rod (564) drives the piston plate (572) to slide toward the inside of the fixed shell (571), so that the airflow inside the fixed shell (571) enters the inside of the curved pipe (573). The airflow passes through the curved pipe (573) and jets air toward the double-pin electronic component in the cutting process. The generated force can jet the pins adhered to the cutting blade (553). Step 4: Improving the cutting accuracy of the cutting knife (553). When the inverted T-plate (563) descends, the inverted T-plate (563) drives the bent rod (581) to move downward, the bent rod (581) drives the connecting plate (582) to move downward, the connecting plate (582) drives the sliding rod (583) to move downward, the sliding rod (583) drives the extrusion shell (584) to move downward, the extrusion shell (584) drives the silicone belt (586) to move downward, and the silicone belt (586) will contact the top of multiple double-pin electronic components during the descent process, thereby preventing the double-pin electronic components from shaking during transportation, thereby improving the cutting accuracy of the cutting knife (553) on the pins of the double-pin electronic components.
