Description

Technical Field

[0001] This utility model relates to the field of electronic component pin correction technology, and in particular to an automatic pin correction device for circuit boards. Background Technology

[0002] In the field of electronic circuits, electronic components are the basic units that make up circuits. The shape of their pins directly affects the installation accuracy and circuit performance. Currently, most electronic components use copper pins, but the material is soft and is easily deformed or bent due to bumps or squeezing during replacement and disassembly. Although operators can manually correct it, it is difficult to completely restore the flatness of the pins, which often leads to problems such as jamming and poor contact during installation, and even causes circuit failure.

[0003] In the prior art, patent CN221603115U proposes an electronic component pin straightening device. This device uses a cylinder to drive a straightening plate to press bent pins into straightening blocks for flattening. However, this solution has significant technical bottlenecks: First, its adaptability is limited. The spacing between the straightening blocks is fixed, limiting its application to electronic components with a single pin spacing. When faced with different package types, it cannot quickly adjust the position of the straightening structure, requiring the replacement of the entire bracket or straightening blocks, which is time-consuming, labor-intensive, and costly. Second, its adjustment flexibility is insufficient. The fixing bracket and cylinder... The relatively fixed position makes it difficult to adapt to the pin layout of electronic components of different sizes. For example, for wide-pitch or close-pitch components, the pressure path of the pressure plate cannot accurately match the pin position, which may result in uncorrected areas or excessive compression of adjacent pins. Thirdly, there is a lack of versatility. The equipment lacks a dynamic adjustment mechanism and cannot meet the needs of rapid switching in small-batch, multi-variety production scenarios. Especially in scenarios such as electronic repair and prototype development that require frequent handling of components of different specifications, the equipment utilization rate is low. It is evident that the technology has certain defects and shortcomings, and therefore, it needs to be improved and designed. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an automatic pin alignment device for circuit boards, which can more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes an automatic circuit board pin correction device, including a base, with support legs fixedly installed at the four corners of the top of the base, a top seat fixedly installed on the top of the support legs, a positioning mechanism fixedly installed in the middle of the top seat, a placement seat fixedly installed in the middle of the top of the top seat, a circuit board body placed on the top of the placement seat, pins to be corrected fixedly connected at equal intervals on the outer side of the circuit board body, a correction mechanism fixedly installed on one side of the top of the base, and adjustment components fixedly installed in the middle of both sides of the base.

[0007] The corrective mechanism includes a support rod, which is fixedly installed on one side of the top front end of the base. A top plate is fixedly installed on the top of the support rod. An electric push rod is fixedly installed on the top of the top plate near the middle of the base. The output end of the electric push rod passes through the top plate and is fixedly installed with a corrective plate. Slide grooves are provided on both sides of the corrective plate. Several sets of corrective clamps are movably connected inside the slide grooves. A cover plate is fixedly installed at the bottom of the corrective plate, and the cover plate covers the bottom of the corrective clamps.

[0008] Furthermore, the positioning mechanism includes a guide rail, which is fixedly installed in the middle of the top seat. A drive motor is fixedly installed at one end of the guide rail, and a lead screw is fixedly installed through the output end of the drive motor. The two ends of the lead screw have opposite thread directions, and both ends of the lead screw are threadedly connected to sliders. A clamping arm is fixedly installed on the top of the slider, and a clamping plate is fixedly connected to the top of the clamping arm.

[0009] Furthermore, the adjustment assembly includes a side rail, which is fixedly installed on the middle of both sides of the top seat. A movable block is slidably connected inside the side rail. An inner corrective clamp is fixedly installed on the top of the movable block. A side mounting screw is threadedly connected to the outside of the movable block. The end of the side mounting screw passes through the movable block. The pin to be corrected covers the outside of the inner corrective clamp.

[0010] Furthermore, the corrective clamp assembly includes a sliding block, which is slidably connected to the inside of a slide groove. A limiting arm is fixedly connected to the outside of the sliding block. An upper mounting screw is threadedly connected to the top of the limiting arm. The end of the upper mounting screw passes through the limiting arm. An adjustment assembly is fixedly connected to the bottom of the limiting arm.

[0011] Furthermore, the adjustment assembly includes a bottom rail, which is fixedly connected to the bottom of the limiting arm. A slide bar is slidably connected inside the bottom rail, and a correction arm is fixedly installed at the outer end of the slide bar. Correction outer arms are fixedly installed on both outer sides of the correction arm. The correction outer arms cover the outer side of the pin to be corrected away from the main body of the circuit board, and the correction arms are located on both sides of the pin to be corrected.

[0012] Furthermore, the bottom inner end of the slide bar is threaded with a lower mounting screw, the end of which penetrates the slide bar, and the side mounting screw, lower mounting screw, and upper mounting screw are all hand-tightening screws.

[0013] Furthermore, the bottom of the side rail is provided with equal-spaced limiting holes, and the end of the side mounting screw is inserted into the limiting hole.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device achieves efficient correction of circuit board pins through a correction mechanism. During operation, after the circuit board is placed on the placement seat, the drive motor drives the reverse threaded screw to rotate, causing the slider to slide in opposite directions within the guide rail. This causes the clamping arm and clamping plate to precisely fit against both sides of the circuit board, achieving stable clamping. At the same time, the pin to be corrected is initially limited by the inner correction clamping plate and the correction limiting arm. After the electric push rod is activated, the correction plate moves downward, and the cover plate first contacts the circuit board to form support. The correction arm is inserted into both sides of the pin, and together with the correction limiting arm and the inner correction clamping plate, it squeezes and corrects from multiple directions, effectively correcting pin deformation.

[0016] 2. During the application of this device, it has the ability to be flexibly adjusted to adapt to circuit boards of different specifications. By adjusting the movable block in the side rail, the inner straightening clamp is moved to adapt to the inner support of the pin; by adjusting the sliding block in the slide groove, the straightening arm and the straightening limit arm are moved laterally to match the straightening position on the outside of the pin, and are fixed with the upper mounting screw. When it is necessary to adjust the span of the straightening limit arm, the upper mounting screw is loosened to pull out the sliding block, and the lower mounting screw is adjusted to make the slide bar slide on the bottom rail, which drives the straightening arm to extend and retract to adapt to different pin lengths and degrees of deformation.

[0017] 3. During application, the adjustment mechanism of this device enables it to have good versatility and operational flexibility. It can be quickly adapted to various packaged circuit boards. Different pin spacing and span can be adapted with simple adjustments, improving the versatility and operational efficiency of the equipment. The multi-directional synchronous extrusion correction method improves the pin correction accuracy and consistency, reduces installation problems caused by pin deformation, and improves the installation quality and reliability of circuit boards. It is suitable for multiple scenarios in electronic manufacturing and repair, providing a reliable solution for pin correction, and helping to improve production efficiency, reduce costs, and improve product quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] An automatic pin correction device for circuit boards includes a base 1, with support legs 2 fixedly installed at the four corners of the top of the base 1, a top seat 3 fixedly installed on the top of the support legs 2, a positioning mechanism 6 fixedly installed in the middle of the top seat 3, a placement seat 5 fixedly installed in the middle of the top of the top seat 3, a circuit board body 4 placed on the top of the placement seat 5, pins 7 to be corrected being fixedly connected at equal intervals on the outer side of the circuit board body 4, a correction mechanism 8 fixedly installed on one side of the top of the base 1, and adjustment components 9 fixedly installed in the middle of both sides of the base 1.

[0028] The correction mechanism 8 includes a support rod 81, which is fixedly installed on one side of the top front end of the base 1. A top plate 82 is fixedly installed on the top of the support rod 81. An electric push rod 83 is fixedly installed on the top of the top plate 82 near the middle of the base 1. The output end of the electric push rod 83 passes through the top plate 82 and is fixedly installed with a correction plate 84. Slide grooves 85 are provided on both sides of the correction plate 84. Several sets of correction clamps 86 are movably connected inside the slide grooves 85. A cover plate 87 is fixedly installed on the bottom of the correction plate 84, covering the bottom of the correction clamps 86. During the use of this device, the circuit board body 4 can be placed on the placement seat 5 on the top of the top base 3. The positioning mechanism 6 in the middle of the top base 3 then fixes the circuit board. After positioning, the adjustment components 9 in the middle of both sides of the base 1... The adjustment can be made according to parameters such as the pin spacing and size of the circuit board to ensure that components such as the inner straightening clamp 93 are in the right position. Then, the straightening mechanism 8 is activated, and the electric push rod 83 installed on the top plate 82 of the support rod 81 on one side of the base 1 starts to operate. Its output end pushes the straightening plate 84 vertically downward. The cover plate 87 at the bottom of the straightening plate 84 first contacts the top of the circuit board to form a stable support surface to prevent the circuit board from shifting during the straightening process. At the same time, the straightening clamp group 86 in the sliding groove 85 on both sides of the straightening plate 84 moves down. The straightening arms 8643 of the straightening clamp group 86 are precisely inserted into both sides of the pin 7 to be straightened. The straightening limit arm 862 covers the outside of the pin and works with the inner straightening clamp 93 to squeeze the pin synchronously from multiple directions to achieve automatic straightening of the deformed pin. The whole process is efficient and accurate.

[0029] Combination Figures 1-3 As shown, the positioning mechanism 6 includes a guide rail 61, which is fixedly installed in the middle of the top seat 3. A drive motor 62 is fixedly installed at one end of the guide rail 61. A lead screw 63 is fixedly installed through the guide rail 61 at the output end of the drive motor 62. The two ends of the lead screw 63 have opposite threads. A slider 64 is threaded to both ends of the lead screw 63. A clamping arm 65 is fixedly installed on the top of the slider 64. A clamping plate 66 is fixedly connected to the top of the clamping arm 65. The adjustment component 9 includes a side rail 91, which is fixedly installed in the middle of both sides of the top seat 3. A movable block 92 is slidably connected inside the side rail 91. An inner straightening clamp 93 is fixedly installed on the top of the movable block 92. A side mounting screw 94 is threaded to the outside of the movable block 92. The end of the side mounting screw 94 passes through the movable block 92. The pin to be straightened 7 covers the outside of the inner straightening clamp 93.

[0030] In the above-described embodiments of this application, during the use of this device, when the circuit board body 4 is placed on the placement seat 5 of the top seat 3, the drive motor 62 at one end of the guide rail 61 is started, and its output end drives the lead screw 63 to rotate. Since the threads at both ends of the lead screw 63 rotate in opposite directions, the sliders 64 on both sides slide synchronously towards each other in the guide rail 61, driving the clamping plate 66 at the top of the clamping arm 65 to move in opposite directions, thereby achieving stable clamping and positioning of the circuit board body 4 of different sizes. At the same time, the pins 7 to be corrected naturally cover the outside of the inner correction clamping plate 93. The operator can adjust the movable block 92 in the side rail 91 according to the pin spacing, drive the inner correction clamping plate 93 to move to a suitable position, and then tighten the side mounting screw 94 so that its end passes through the movable block 92 and abuts against the side rail 91, thereby locking the movable block 92 and ensuring that the inner correction clamping plate 93 is accurately supported on the inside of the pin, providing a foundation for the subsequent correction process.

[0031] Example 2

[0032] Combination Figures 3-6 As shown, the corrective clamp assembly 86 includes a sliding block 861, which is slidably connected to the inside of a slide groove 85. A limiting arm 862 is fixedly connected to the outside of the sliding block 861. An upper mounting screw 863 is threadedly connected to the top of the limiting arm 862, and the end of the upper mounting screw 863 passes through the limiting arm 862. An adjustment assembly 864 is fixedly connected to the bottom of the limiting arm 862. The adjustment assembly 864 includes a bottom rail 8641, which is fixedly connected to the bottom of the limiting arm 862. A slide bar 8642 is slidably connected inside the bottom rail 8641, and a corrective arm 8643 is fixedly mounted on the outer end of the slide bar 8642. Correction arms 8644 are fixedly installed on both sides of the outer side of the correction arm 8643. The correction arms 8644 cover the outer side of the pin 7 to be corrected away from the main body of the circuit board 4. The correction arms 8643 are set on both sides of the pin 7 to be corrected. The bottom inner end of the slide bar 8642 is threaded with a lower mounting screw 8645. The end of the lower mounting screw 8645 passes through the slide bar 8642. The side mounting screw 94, the lower mounting screw 8645 and the upper mounting screw 863 are all set as hand-tight screws. Limiting holes 95 are opened at equal intervals in the bottom of the side rail 91. The end of the side mounting screw 94 is inserted into the inside of the limiting hole 95.

[0033] The technical solution described in the above-described embodiments of this application, during the use of this device, when using the automatic pin correction device for the circuit board, the working process of the correction clamp group 86 is as follows: The operator can manually loosen the upper mounting screw 863 according to the spacing of the pins 7 to be corrected, allowing the sliding block 861 to slide laterally within the groove 85 of the correction plate 84, driving the limiting arm 862 and the lower adjustment group 864 to shift, precisely adjusting the lateral spacing between the correction arm 8643 and the pins; after completing the lateral position adjustment, tighten the upper mounting screw 863 through the limiting arm 862 to fix the sliding block 861; depending on the length or degree of deformation of the pins, the lower mounting screw 8645 can be loosened to drive... The movable slider 8642 slides longitudinally within the bottom rail 8641, causing the straightening arm 8643 and its outer straightening arm 8644 to extend and retract radially, so that the outer straightening arm 8644 covers the outside of the pin away from the main body 4 of the circuit board, ensuring that the straightening arm 8643 is accurately positioned on both sides of the pin. After adjustment, the lower mounting screw 8645 is tightened to fix the slider 8642 in place. In addition, the position of the inner straightening clamp 93 can be adjusted by the limiting hole 95 at the bottom of the side rail 91 and the side mounting screw 94. Together with the straightening clamp group 86, a multi-faceted compression straightening structure is formed from the inside and outside of the pin and both sides, so as to complete the flexible adaptation and precise straightening of pins of different specifications.

[0034] The working principle and advantages of this utility model are as follows: This device achieves efficient correction of circuit board pins through the correction mechanism 8. In actual operation, after the circuit board body 4 is placed on the placement seat 5 of the top seat 3, the operator starts the drive motor 62. The rotational motion of the motor output shaft is transmitted to the lead screw 63 through the coupling. Since the threads at both ends of the lead screw 63 are turned in opposite directions, when the lead screw 63 rotates, the sliders 64 on both sides will slide synchronously and in opposite directions in the guide rail 61. The advantage of this bidirectional synchronous adjustment mechanism is that, regardless of whether the circuit board is a small module or a standard PCB board, the sliding of the sliders 64 can make the clamping arm 65 drive the clamping plate 66 to accurately fit the two sides of the circuit board, achieving stable clamping and positioning. During this process, the pin 7 to be corrected naturally covers the outside of the inner correction clamping plate 93, while the inner correction clamping plate 93 fills the inside of the pin, forming the initial limit of the pin, creating good conditions for subsequent correction operations.

[0035] Subsequently, the operator activates the electric push rod 83. The linear motion of the electric push rod 83 pushes the straightening plate 84 vertically downward. At this time, the cover plate 87 first contacts the top of the circuit board and forms a stable support plane. The importance of this design is that it can effectively prevent the circuit board from warping or shifting due to uneven pressure during the straightening process. As the straightening plate 84 continues to descend, the straightening arm 8643 will accurately insert into the gaps on both sides of each pin 7 to be straightened. At the same time, the straightening limiting arm 862 simultaneously covers the outer edge of the pin. In this way, the inner side of the pin 7 to be straightened is squeezed by the inner straightening clamp 93, the outer side is squeezed by the straightening limiting arm 862, and both sides are squeezed by the straightening arm 8643, forming a three-dimensional straightening structure. This multi-directional synchronous squeezing straightening method can comprehensively and effectively correct the bending, offset and other deformation problems of the pin, ensuring that the pin achieves a good straightening effect.

[0036] During the correction process, the equipment has flexible adjustment capabilities to adapt to circuit boards of different specifications. The operator can adjust the sliding block 92 in the side rail 91 to move the inner correction clamp 93. This adjustment method can flexibly adapt to the inner support requirements of different pin spacings, ensuring that the inner correction clamp 93 can accurately support the inner side of the pins, providing a stable foundation for the correction operation. On this basis, the operator can also adjust the sliding block 861 in the slide groove 85 to move the correction arm 8643 and the correction limiting arm 862 laterally. Through this adjustment, the outer correction position of different pin spacings can be easily matched, so that the correction limiting arm 862 can accurately cover the outer side of the pins. After the adjustment is completed, the operator only needs to turn the upper mounting screw 863 to fix the sliding block 861 in the required position, ensuring that the sliding block 861 will not be displaced during the correction process, thus ensuring the stability of the correction operation.

[0037] When it is necessary to adjust the span of the correction limit arm 862, the operator can first loosen the upper mounting screw 863 and pull the sliding block 861 out of the slide groove 85. Then, by twisting the lower mounting screw 8645, the slide bar 8642 can be driven to slide in the bottom rail 8641, thereby driving the correction arm 8643 and the correction limit arm 862 to perform radial extension and retraction. This design allows the equipment to further adapt to pins of different lengths or degrees of deformation, expanding the applicability of the equipment. After adjustment, it is inserted into the slide groove 85, and then the slider 64 is adjusted and adapted.

[0038] The aforementioned series of adjustment mechanisms endow the equipment with strong versatility and operational flexibility. It can quickly adapt to circuit boards of various packaging forms without replacing hardware. With simple adjustments, it can adapt to different pin spacings and spans. This not only significantly improves the equipment's versatility but also greatly increases operational efficiency, reducing time wasted due to equipment replacement or parameter adjustments. Through multi-directional synchronous extrusion correction, the equipment can effectively improve the accuracy and consistency of pin correction, controlling the pin straightness error within a very small range. This advantage can reduce installation difficulties and poor contact caused by pin deformation, improving the installation quality and reliability of circuit boards. It is suitable for various scenarios in electronic manufacturing and repair, providing a reliable solution for efficient pin correction of circuit boards. In the electronic manufacturing industry, this efficient and precise pin correction equipment can improve production efficiency, reduce production costs, and improve product quality.
