Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device processing technology, and in particular to a resistor cutting and bending machine. Background Technology
[0002] With the continuous advancement and development of science and technology, the variety of electronic devices on the market is increasing, including temperature sensors, potentiometers, electronic transformers, and relays, which play an increasingly important role in various sectors of the national economy, such as the automotive industry. Among these, resistor leads are crucial structures used for connecting to other electronic devices, and their quality directly affects the performance of the electronic components. Typically, resistor leads are manufactured using alloys with specific resistivity, such as nickel-chromium, manganese-copper, and constantan, to create resistor strips. These strips are then manually cut and bent.
[0003] For example, patent application number CN202123245975.5 discloses an automatic resistor cutting and bending device, including a feeding component, a cutting component, a bending component, and a gripping mechanism. The feeding component automatically feeds the resistor strip to be processed into the cutting component, which then cuts the resistor strip. The gripping mechanism then transports the cut resistor strip to the bending component for bending. Compared with traditional manual operation, this device can automatically rotate, feed, cut the resistor leads, and bend the resistor strip, achieving a high degree of automation and effectively improving work efficiency. While the resistor material is cut and bent by the cutting and bending components, the transfer of the resistor material requires an additional gripping mechanism. This gripping mechanism takes time during the material handling process, affecting the continuous production efficiency of the resistor material and needs optimization. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a resistance cutting and bending machine, including a machine base 1 and a base 2. The machine base 1 is fixedly installed on the upper end of the base 2. A track plate 7 is provided in front of the machine base 1, and a frame structure for supporting the track plate 7 is provided on the left and right sides of the machine base 1.
[0023] The machine base 1 is equipped with a bending mechanism and a shearing mechanism on the side near the track plate 7. The bending mechanism is located above the track plate 7, and the shearing mechanism is located above and below the track plate 7. The machine base 1 is equipped with a transmission device for controlling the operation of the bending mechanism and the shearing mechanism.
[0024] The track plate 7 has a reel structure on one side for winding the resistive adhesive tape, and the base 2 has a material collection device at the upper end, which is located below the shearing mechanism.
[0025] The resistive adhesive tape with the resistive element attached is laid flat on the track plate 7. One end of the tape is wound around the reel structure. The reel structure controls the tape to roll up, so that the tape moves horizontally on the track plate 7. When it passes through the bending mechanism, the bending mechanism will bend the metal feet of the resistive element on the tape. After bending, the resistive element will pass through the middle of the shearing mechanism. The shearing mechanism will cut off the metal feet on the resistive element, so that it falls into the collection device for centralized collection.
[0026] The bending and shearing mechanisms are installed on the machine base 1. Without the need for additional gripping equipment, the bending, cutting and collection of resistor components can be completed sequentially. The bending and cutting of resistor components are controlled uniformly by the transmission device, which is highly integrated and effectively improves the processing efficiency of resistor components.
[0027] Specifically, the frame structure includes a support plate 8. One end of the support plate 8 is fixedly connected to the machine base 1 by bolts, and the other end of the support plate 8 extends below the track plate 7. The track plate 7 is fixedly connected to the support plate 8 by bolts. The support plate 8 supports the track plate 7 from the bottom. When the track plate 7 is removed from the machine base 1 for replacement, the bolts between the track plate 7 and the support plate 8 can be released.
[0028] Specifically, the bending mechanism includes a first power plate 10, which is fixedly mounted on the front of the machine base 1. A first power wheel 12 is provided at the upper end of the first power plate 10, and the first power wheel 12 is rotatably connected to the first power plate 10. A first sliding frame 14 is provided below the first power plate 10, and the first sliding frame 14 is slidably connected to the limiting groove 11 opened on the first power plate 10. A first rocker arm 13 is provided between the first power wheel 12 and the first sliding frame 14. One end of the first rocker arm 13 is hinged to the first sliding frame 14, and the other end of the first rocker arm 13 is hinged to the eccentric rod on the first power wheel 12. A pressure roller 15 is provided at the end of the first sliding frame 14 away from the first power plate 10, and the pressure roller 15 is offset from the track plate 7.
[0029] The first power plate 10, the first power wheel 12, the first rocker arm 13, and the first sliding frame 14 constitute a crank-slider mechanism. The first power wheel 12 drives the first rocker arm 13 to rotate during rotation. The other end of the first rocker arm 13 pulls the first sliding frame 14. The limiting groove 11 on the first power plate 10 guides the first sliding frame 14, converting the rotational motion of the first power wheel 12 into the vertical reciprocating motion of the first sliding frame 14. After the first sliding frame 14 falls, it will bend the metal resistor feet on the resistor adhesive tape.
[0030] Specifically, the shearing mechanism includes a second power plate 16, which is fixedly mounted on the front of the machine base 1. The upper and lower ends of the second power plate 16 are provided with second power wheels 17, which are rotatably connected to the second power plate 16. Two second sliding frames 19 are provided between the two second power wheels 17. The track plate 7 passes between the two second sliding frames 19. The second sliding frames 19 are slidably connected to the limiting grooves 11 opened on the second power plate 16. A second rocker arm 18 is provided between the second power wheels 17 and the second sliding frames 19. One end of the second rocker arm 18 is hinged to the second sliding frame 19, and the other end of the second rocker arm 18 is hinged to the eccentric rod on the second power wheel 17. A cutter 20 is provided at the end of the second sliding frame 19 away from the second power plate 16. The cutter 20 is offset from the track plate 7.
[0031] The two cutters 20 are also staggered. After the bending of the resistor metal feet is completed, the two second power wheels 17 on the second power plate 16 rotate together. As the second power wheels 17 rotate, they pull the second sliding frame 19 through the second rocker arm 18, controlling the two second sliding frames 19 to move closer and separate. When the two second sliding frames 19 approach each other, the two sets of cutters 20 will form a shearing force to cut off the resistor metal feet on the resistor adhesive tape.
[0032] Regarding the transmission device:
[0033] The transmission device includes three rotating rollers 21 located inside the machine base 1. Each rotating roller 21 is fixedly connected to a first power wheel 12 and a second power wheel 17, respectively. A pulley 22 is fitted onto the outer side of each rotating roller 21, and adjacent pulleys 22 are connected by a synchronous belt. A motor 23 is fixedly installed inside the machine base 1, and the output end of the motor 23 is fixedly connected to one of the rotating rollers 21. The motor 23 controls the rotation of the rotating roller 21, which in turn drives another rotating roller 21 to rotate via a belt drive. This third rotating roller then drives the remaining rotating roller 21 to rotate via a belt drive, thereby achieving coordinated control of the first power wheel 12 and the two second power wheels 17.
[0034] To prevent the resistive tape from shifting position during transport, multiple limiting rollers 9 are installed above the track plate 7, and the limiting rollers 9 are rotatably connected to the machine base 1. The limiting rollers 9 limit the resistive tape from above.
[0035] Specifically, the reel mechanism includes a support frame 5 and a reel 6. The support frame 5 is fixedly mounted on one side of the base 2, and the reel 6 is rotatably mounted on the upper end of the support frame 5. A motor for controlling the rotation of the reel 6 is provided on the outside of the support frame 5. By controlling the rotation of the reel 6 through the motor, the reel 6 slowly pulls the resistive adhesive tape spread flat on the track plate 7 during rotation, thereby completing the cutting and bending of the resistance on the resistive adhesive tape.
[0036] Regarding the material collection device:
[0037] The collection device includes a collection box 4, which is slidably disposed in a pull-out groove 3 on the front of the base 2. After the resistor is cut by the shearing mechanism, the resistor will fall into the collection box 4 on the base 2. When the collection box 4 is full of resistors, the collection box 4 is pulled to remove it from the pull-out groove 3.
[0038] How this application works:
[0039] The adhesive tape with the resistive element attached is laid flat on the track plate 7. One end of the tape is wound around the reel 6 of the reel structure. The reel structure controls the reel 6 to wind up the adhesive tape via a motor, so that the tape moves horizontally on the track plate 7. When it passes the bending mechanism, the first power plate 10 drives the pressure roller 15 to press down and bend the metal foot of the resistive element on the tape. After bending, the resistive element moves with the tape to the shearing mechanism. The second power plate 16 drives the two sets of cutters 20 to close and cut off the metal foot. The cut resistive element falls into the collection box 4 for collection.
