Description
Technical Field
[0001] This utility model relates to the field of electronic device pin bending technology, and more specifically, to an electronic device pin bending fixture. Background Technology
[0002] In the electrical industry, capacitors and resistors are commonly used electronic components. These leaded electronic components are soldered onto circuit boards using their leads. Lead bending is a crucial processing step in the manufacturing process of electronic components. The precision and quality of lead bending directly affect the subsequent soldering quality between the electronic component and the circuit board, as well as the overall performance of the electronic device.
[0003] Traditional manual bending methods rely on operators using simple tools such as pliers to bend the leads. This method is not only labor-intensive but also has extremely low processing efficiency. Manual operation is greatly affected by human factors, making it difficult to ensure the consistency of lead bending angles and dimensions, resulting in inconsistent product quality and affecting the subsequent soldering quality. Therefore, a lead bending fixture for electronic devices is proposed. Utility Model Content

[0006] The top of the support plate is provided with a positioning hole. Limiting plates are symmetrically fixedly connected to both ends of one side of the support base. The limiting plates can limit the electronic device placed on the support base to prevent the electronic device from shifting during processing and ensure the accuracy of the pin bending position. A horizontal bending mechanism is provided on one side of the support base. The horizontal bending mechanism can be used to bend the pins after bending one side into shape.
[0007] A first fixing plate is fixedly connected to one side of the top of the support plate. A first electric push rod is fixedly connected to one side of the first fixing plate. A moving plate is connected to the output end of the first electric push rod. Bending pressure plates are symmetrically fixedly connected to both ends of one side of the moving plate. A second groove is provided on the top of the moving plate. A pressure sensor is provided on one side of the moving plate. Activating the first electric push rod controls the moving plate to move the bending pressure plate to one side of the support base. The bending pressure plate bends the pins. The pressure sensor can detect the pressure of the moving plate on the electronic device, avoiding damage to the pins due to excessive pressure or incomplete bending due to insufficient pressure, thereby ensuring the quality and accuracy of pin bending. The second groove facilitates the removal of the electronic device.
[0008] The bottom of the movable plate is fixedly connected to a first limiting slider, and the top of the support plate is provided with a first limiting groove at a position corresponding to the first limiting slider. The stability of the movable plate movement is improved by the cooperation of the first limiting slider and the first limiting groove.
[0009] Preferably, the positioning pin corresponds to the positioning hole, the positioning pin is inserted into the interior of the positioning hole, and one end of the fixing bolt extends to the middle of one of the positioning holes and is threadedly connected to the positioning hole. The positioning pin and the fixing bolt are inserted into the interior of the positioning hole to facilitate the installation and fixing of the support base.
[0010] Preferably, the limiting plate is disposed on the side of the support base near the moving plate, the width of the support base is less than the distance between the two bending pressure plates, and the pressure sensor is disposed between the moving plate and the support base. The limiting plate limits the placement of electronic components and supports the pin end position, facilitating bending.
[0011] Preferably, the cross-sectional shape of the first limiting slider is set to "L" shape, the first limiting slider is located in the middle of the first limiting groove, and the second groove corresponds to the first groove. The stability of the moving plate is improved by the cooperation of the first limiting slider and the first limiting groove.
[0012] Preferably, the horizontal bending mechanism includes a second limiting groove formed on the top of the support plate. The second limiting groove is located on the side of the support base away from the limiting plate. Two movable bending blocks are symmetrically arranged on the top of the second limiting groove. A driving mechanism is provided at the bottom of the support plate. A second limiting slider is fixedly connected to the bottom of the movable bending block.

Activating the second electric push rod controls the movement of the toothed plate, which in turn controls the gear to drive the threaded rod to rotate, thereby driving the threaded rod to move inside the second limiting groove. This allows the two moving bending blocks to move to opposite sides. Combined with the limiting of the needle at one end of the bending pressure plate, a secondary bending of the needle can be achieved, improving the performance.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. This utility model first uses positioning columns and fixing bolts to install and fix the support base, and uses a limiting plate to position the electronic components to ensure accurate positioning. By activating the first electric push rod to control the movement of the bending pressure plate, the pins can be bent longitudinally. By activating the second electric push rod to control the synchronous movement of the moving bending blocks, the pins of the electronic components can be bent laterally, so that the pins of the electronic components reach the required welding state. The bending position is fixed during the bending process, which can effectively improve the bending accuracy of the pins of the electronic components and the product quality, and improve the assembly qualification rate and overall performance of the electronic components.
[0017] 2. This utility model also uses support bars and mounting ear plates to install and fix the support plate. The fixture has a simple and reasonable structural design, mainly composed of conventional mechanical parts and electric drive components. Compared with the existing complex automatic pin bending equipment, the manufacturing cost is greatly reduced. At the same time, during the bending process, the pressure sensor can detect the pressure of the moving plate on the electronic device, avoiding damage to the pin due to excessive pressure or incomplete bending due to insufficient pressure, thereby ensuring the quality and accuracy of pin bending. The second groove facilitates the removal of the electronic device.
[0018] In summary, through the interaction of the above-mentioned functions, electronic components can be easily positioned, ensuring accurate placement. At the same time, the pins of electronic components can be bent longitudinally and laterally to achieve the required soldering state, effectively improving the bending accuracy of the pins and product quality, and enhancing the assembly qualification rate and overall performance of electronic components.

[0028] The bottom of the movable plate 12 is fixedly connected to a first limiting slider 15, and the top of the support plate 1 is provided with a first limiting groove 16 at a position corresponding to the first limiting slider 15. The stability of the movement of the movable plate 12 is improved by the cooperation of the first limiting slider 15 and the first limiting groove 16.
[0029] As attached Figure 1-4 As shown, the positioning pin 6 corresponds to the positioning hole 4 and is inserted into the interior of the positioning hole 4. One end of the fixing bolt 9 extends to the middle of one of the positioning holes 4 and is threadedly connected to the positioning hole 4.

This drives the threaded rod 22 to move inside the second limiting slide groove 18, enabling the two moving bending blocks 19 to move to opposite sides. Combined with the limiting of the needle at one end of the bending pressure plate 13, a secondary bending of the needle can be achieved, improving the performance.
[0031] The working principle of this utility model is as follows: When in use, the electronic device to be processed is placed on the support base 5, and the electronic device is positioned by the limiting plate 8 to ensure that the electronic device is accurately positioned and that the pins of the electronic device are located on both sides of the limiting plate 8.
[0032] During longitudinal bending, the first electric push rod 11 is activated, which pushes the moving plate 12 towards the support base 5. The bending pressure plate 13 moves accordingly and applies pressure to the electronic device pins, thus achieving longitudinal bending of the pins. The pressure sensor 17 monitors the pressure applied to the pins in real time during the bending process to avoid excessive pressure on the electronic device, which could cause damage.
[0033] When performing a lateral bend, the second electric push rod 25 is activated. The extension and retraction of the second electric push rod 25 drives the toothed plate 26 to move. The toothed plate 26, through meshing with the gear 23, causes the threaded rod 22 to rotate, thereby driving the moving bending blocks 19 on both sides to move towards or away from each other in the second limiting slide groove 18 to perform a lateral bend on the electronic device pins.
