Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for electronic component pins. Background Technology

[0002] An electronic component lead bending device is a specialized piece of equipment used for bending, adjusting, and positioning the leads of electronic components. It is commonly used in the production and assembly of electronic components, especially when lead angles or shapes need to be adjusted for soldering or mounting. The main functions of this device include: precision bending: accurately bending component leads to ensure proper alignment with circuit board holes during installation; increased efficiency: significantly improving efficiency in mass production through automation, reducing human error and labor intensity; and quality control: effectively reducing quality problems caused by human factors through mechanized and automated operation, improving the consistency and reliability of lead bending. This device plays a vital role in the electronics manufacturing industry, especially in large-scale production, where it enhances production efficiency and product quality.

[0003] When using electronic component pin bending devices, it is usually necessary to fix the pins. However, some existing bending devices require manual operation by workers when fixing and disassembling the pins, which results in a long pause during fixing and disassembly, leading to low device efficiency. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electronic component pin bending device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electronic component pin bending device includes an operating table. Two support frames are symmetrically fixedly connected to the top of the operating table. A common rotating shaft connects the two support frames rotatably. A motor is fixedly connected to one end of the rotating shaft and to one side of one of the support frames. Four placement boxes are fixedly connected to the surface of the rotating shaft in a ring-shaped, uniform arrangement. Each of the four placement boxes has a bending chamber on one side. Multiple first clamping slots are formed inside each of the four bending chambers. Clamping plates are slidably connected inside each of the four bending chambers. Second clamping slots are formed on the surface of each clamping plate near the multiple first clamping slots, and these second clamping slots cooperate with the first clamping slots. A moving mechanism for moving the clamping plates is provided on the surface of each clamping plate away from the first clamping slots. A storage box is slidably connected inside the operating table near the rotating shaft. Two limiting slots are symmetrically formed on the surface of the operating table near the storage box. Each of the two limiting slots has a constraint mechanism for constraining the storage box. The clamping plates significantly improve the device's working efficiency.

[0007] As a further embodiment of this utility model, the moving mechanism includes three reciprocating lead screws, all of which are rotatably connected inside the placement box. The same sliding plate is fitted onto the surface of the three reciprocating lead screws. Three connecting posts are fixedly connected to the surface of the sliding plate near the clamping plate, and the three connecting posts are slidably connected to one side of the bending chamber. The clamping plate is fixedly connected to the other end of the three connecting posts. The surface of each of the three reciprocating lead screws is provided with a rotating mechanism for rotating the reciprocating lead screws. By setting the reciprocating lead screws, the clamping plate can be moved.

[0008] As a further embodiment of this utility model, the rotating mechanism includes a worm gear rotatably connected to one side of the placement box. A worm wheel is fitted onto the surface of the worm gear, and the worm wheel is sleeved on the surface of the reciprocating lead screw. A gear is sleeved on one end of the worm gear. An adjusting ring is fixedly connected to the surface of the support frame near the gear. A first rack and a second rack are fixedly connected inside the adjusting ring, and both the first rack and the second rack cooperate with the gear. The racks allow the gear to rotate.

[0009] As a further embodiment of this utility model, the constraint mechanism includes a handle, which is fixedly connected to one side of the storage box. Two limiting rods are fixedly connected inside the handle, and the same pull plate is sleeved on the surface of the two limiting rods. A limiting plate is fixedly connected to the surface of the pull plate near the limiting groove, and the limiting plate is slidably connected inside the limiting groove. Tension springs are sleeved on the surface of the two limiting rods near the limiting plate, with one end of each tension spring fixedly connected to one side of the pull plate, and the other end of each tension spring fixedly connected to one side inside the handle. A gantry frame is fixedly connected to one side of the top of the operating table, and two hydraulic rods are fixedly connected to the top of the gantry frame. The same pressure plate is fixedly connected to the bottom of the two hydraulic rods, and the pressure plate cooperates with the storage box. The limiting plate constrains the storage box.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a clamping plate to hold the pins, thus avoiding manual clamping by workers. This effectively solves the problem of low efficiency caused by manual operation during pin fixing and disassembly in some existing bending devices, which require long pauses during these processes. After the pin is bent, the shaft continues to rotate. Because the second rack is installed below the adjusting ring, the gear engages with the second rack as the shaft continues to rotate, causing the worm to continue rotating. When the worm drives the reciprocating screw to rotate again via the worm wheel, the reciprocating screw resets the clamping plate, releasing the pin from clamping. Since both pin clamping and disassembly are completed during device operation, overall work efficiency is greatly improved. Attached Figure Description

[0021] Reference Figure 1 - Figure 6 An electronic component pin bending device includes an operating table 1.

[0022] Reference Figure 4 and Figure 5 In a preferred embodiment, the moving mechanism includes three reciprocating lead screws 309, all of which are rotatably connected to the inside of the placement box 302. The same sliding plate 308 is fitted on the surface of the three reciprocating lead screws 309. The clamping plate 305 can be moved by the sliding plate 308. Three connecting posts 307 are fixedly connected to the surface of the sliding plate 308 near the clamping plate 305, and the three connecting posts 307 are slidably connected to one side of the bending chamber 303. The clamping plate 305 is fixedly connected to the other end of the three connecting posts 307. The surface of each of the three reciprocating lead screws 309 is provided with a rotating mechanism for rotating the reciprocating lead screws 309. The clamping plate 305 can be moved by the reciprocating lead screws 309.

[0023] Reference Figure 4 - Figure 5 In a preferred embodiment, the rotating mechanism includes a worm gear 311, which is rotatably connected to one side of the placement box 302. A worm wheel 310 is fitted on the surface of the worm gear 311 and is sleeved on the surface of the reciprocating lead screw 309. The reciprocating lead screw 309 can be rotated by the worm wheel 310. A gear 312 is sleeved on one end of the worm gear 311. An adjusting ring 313 is fixedly connected to the surface of the support frame 101 near the gear 312. A first rack 314 and a second rack 315 are fixedly connected inside the adjusting ring 313, and the first rack 314 and the second rack 315 are both engaged with the gear 312. The gear 312 can be rotated by the racks.

[0024] Reference Figure 1 and Figure 2 In a preferred embodiment, the restraint mechanism includes a handle 201, which is fixedly connected to one side of the storage box 2. Two limiting rods 202 are fixedly connected inside the handle 201. A pull plate 204 is sleeved on the surface of the two limiting rods 202. A limiting plate 205 is fixedly connected to the surface of the pull plate 204 near the limiting groove 105. The limiting plate 205 is slidably connected inside the limiting groove 105.

On the side, the other ends of the two tension springs 203 are fixedly connected to the inside side of the handle 201. The tension springs 203 can reset the limiting plate 205. A gantry frame 102 is fixedly connected to the top side of the operating table 1. Two hydraulic rods 103 are fixedly connected to the top of the gantry frame 102. The same pressure plate 104 is fixedly connected to the bottom of the two hydraulic rods 103. The pressure plate 104 can be used to bend the pins. The pressure plate 104 and the placement box 302 are set together. The limiting plate 205 can constrain the storage box 2.

[0025] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the pin to be bent is placed between the first clamping groove 304 and the second clamping groove 306, and then the motor 3 is started. Because the placement box 302 is connected to the motor 3 through the rotating shaft 301, the rotating shaft 301 can drive the placement box 302 to rotate after the motor 3 starts. A worm gear 311 is installed on one side of the placement box 302, and the worm gear 311 cooperates with the adjusting ring 313 through the gear 312. The first gear 311 is installed inside the adjusting ring 313. A first rack 314 and a second rack 315 are used. When the rotating shaft 301 initially rotates, the gear 312 engages with the first rack 314, enabling the worm 311 to rotate synchronously. A worm wheel 310 is fitted onto the surface of the worm 311, and the worm wheel 310 is sleeved on the surface of the reciprocating screw 309. Thus, when the worm 311 rotates, the reciprocating screw 309 also rotates synchronously. A slide plate 308 is installed on the surface of the reciprocating screw 309, and a clamping plate 305 is installed on one side of the slide plate 308. Because the slide plate 308 is constrained inside the placement box 302, when the reciprocating screw 309 rotates... When the 9-pin rotates, the slide plate 308 can move forward, allowing the first clamping groove 304 and the second clamping groove 306 to clamp and fix the pin. As the rotating shaft 301 continues to rotate, the clamped pin will turn to one side. A pressure plate 104 is installed on one side of the rotating shaft 301, and the pressure plate 104 cooperates with the hydraulic rod 103. When the pin rotates to the correct position, the hydraulic rod 103 will drive the pressure plate 104 to move downward, allowing the pressure plate 104 to bend the pin. When the pressure plate 104 bends the current pin, subsequent pins can be placed in other placement boxes 302. Internally, after the pin is bent, the rotating shaft 301 will drive it to continue rotating. Since the second rack 315 is installed at the lower part of the adjusting ring 313, as the rotating shaft 301 continues to rotate, the gear 312 will engage with the second rack 315, thereby causing the worm 311 to continue rotating. When the worm 311 drives the reciprocating screw 309 to rotate again through the worm wheel 310, the reciprocating screw 309 will drive the clamping plate 305 to reset, thereby releasing the pin from the clamp. Since the clamping and disassembly of the pin are both completed during the operation of the device, the overall working efficiency can be greatly improved.
