Description

Technical Field

[0001] This invention relates to the field of amplifier board wiring technology, and more particularly to a quick alignment wiring device for current amplifier boards. Background Technology

[0002] The current amplifier board is a PCB circuit board integrating a current amplifier chip, sampling circuit, power supply interface, and multiple sets of signal terminals. It primarily amplifies weak sampled current signals and is widely used in motor drives, power supply detection, and industrial measurement and control equipment. The board has multiple wiring interfaces, requiring connection to input sampling lines, power supply harnesses, and output signal lines to achieve signal acquisition and amplified signal transmission. This board has high requirements for connection accuracy; misaligned wires, skewed pins, or poor contact will directly cause amplified signal distortion and large sampling errors, and in severe cases, may cause a short circuit. Most current amplifier boards with burnt-out circuits have multiple wire harness interfaces. During production, assembly, and testing, the wiring harnesses are often manually connected one by one. Manual connection lacks physical alignment constraints, which can easily lead to misalignment, slant insertion, and reversed wire sequence, causing pin bending, loose connections, and fluctuations in the sampling signal. Aligning multiple terminals one by one is time-consuming, resulting in low assembly efficiency in mass production. The pins of the board terminals are small, and uneven manual force can easily damage the solder pads, causing the copper foil to peel off. Improper connection will increase contact resistance, causing the contact points to heat up during operation, affecting the current amplification accuracy and the overall stability of the machine.

[0003] The wiring process for current amplifier boards still suffers from insufficient alignment accuracy. Manual wiring lacks precise physical alignment guides, and the alignment of multiple wire harnesses with board terminal holes relies entirely on the operator's visual inspection and touch. This easily leads to misalignment, slant insertion, and reversed wiring sequences, causing terminal pin bending, loose connections, and consequently, fluctuations in sampling signals and distortion in amplified signals, making it difficult to ensure the consistency of the board's electrical performance. Furthermore, batch assembly is inefficient. Current production assembly and testing processes mostly rely on manual, one-by-one wiring. Multiple terminals on a single board must be matched and inserted one by one, resulting in long single-station operation times that are difficult to match the cycle time requirements of large-scale production lines. Mass production capacity is significantly limited; the risk of board damage is high, as the structure of board terminal pins and pads is delicate, and it is difficult to consistently control the direction and force during manual insertion. Forced insertion can easily damage the pads and cause copper foil to peel off; insufficient insertion depth will increase the contact resistance of the contact points, and the contact points will overheat severely during long-term operation, which will affect the current amplification accuracy and reduce the stability and service life of the entire machine; the smoothness of process connection is poor, and the existing operation is mostly decentralized manual operation. The board loading and positioning, wire harness feeding and guiding, and insertion actions lack a smooth automated connection. The transfer and repeated alignment between processes are time-consuming, and multiple manual handling can easily cause secondary impact damage to the boards.

[0004] To address the aforementioned issues, a rapid alignment and wiring device for current amplifier boards is proposed. Summary of the Invention

It aims to improve the current amplifier board insertion operation, which relies heavily on manual operation and suffers from problems such as insufficient alignment accuracy, low insertion efficiency, easy damage to boards, and poor process connection. These problems can easily lead to insertion defects and signal distortion, restrict production capacity, and affect product performance and service life.

The two slide rails 914 are fixedly connected to the top left and right sides of the drive cylinder 916, arranged parallel to each other in the left and right direction, and slide in cooperation with the slider 913 to constrain the left and right displacement trajectory of the moving plate 912, ensuring the straightness of the coarse alignment process. The drive rod 911 is installed on the top of the fixed plate 906 and serves as a transmission component for the displacement of the moving plate 912, converting the rotational motion of the motor 907 into the linear motion of the moving plate. The various guide components cooperate with each other to ensure the smooth operation and positional accuracy of the insertion action from multiple dimensions, providing structural support for high-quality insertion.

[0031] Limiting plate 503 is located in front of guide wheel 504. The inner wall of limiting plate 503 is opposite to the outer wall of wire harness body 507, limiting the lateral movement range of wire harness body 507 from the side to prevent the wire harness from coming off the guide wheel during feeding. The outer wall of wire harness body 507 is sequentially wrapped around the outer wall of limiting rod 502, the outer wall of guide wheel 504, and the outer wall of guide wheel 506. After multiple turns and supports, it maintains a straight feeding posture to enter the subsequent work station. The two ends of spring 508 are respectively hooked to the top side wall of mounting bracket 4 and the outer side wall of adjusting rod 505 for adjustment. The link 505 provides elastic tension, allowing the guide wheel 506 to swing slightly with changes in wire harness tension, absorbing tension fluctuations during wire feeding and maintaining stable wire harness tension. The outer walls of the drive wheel 809 and the limit wheel 810 are both in contact with the outer wall of the wire harness body 507. The two work together to clamp the wire harness, and the friction force drives the wire harness forward at a constant speed. The two limit wheels 812 are located on the upper and lower sides of the wire harness body 507, respectively, forming a vertical limit constraint on the wire harness to prevent it from jumping up and down, further improving the posture stability of the wire harness feeding and laying the foundation for precise alignment.

[0032] The threaded rod 606 is rotatably connected to the front and rear ends of the right side of the frame 1, arranged along the front-rear direction. It serves as a transmission component for adjusting the position of the second limiting plate 607. Its rotation drives the second limiting plate 607 to translate. Two limiting rods 603 are fixedly installed on the right side of the mounting plate 3, arranged vertically in parallel, and pass through the inner wall of the lifting plate 604. They provide precise guidance for the lifting movement of the lifting plate 604, preventing twisting or skewing during lifting and ensuring a stable lifting posture for the plate. The inner sides of the two limiting plates 607 are connected to the mounting plate 3. The front and rear sides of the main body 12 of the large plate fit together, forming a positioning constraint on the stacked plates from the front and rear direction, so that the plates are always kept on the lifting path and the position is consistent each time they are lifted. The two ends of the limiting rod 703 are respectively fixedly connected to the inner side wall of the two mounting plates 701 and are set parallel to the driving rod 702. Together they support and guide the translational movement of the moving block 704, preventing the moving block 704 from rotating and deviating, ensuring the accuracy of the loading and unloading displacement, and allowing the suction rod to accurately align with the suction position of the plate.

[0033] The clamping end of the clamping cylinder 2 919 is positioned opposite to the inner wall of the connector plate 920. During the insertion operation, the clamping end of the clamping cylinder 2 919 extends to clamp and fix the end of the wire harness body 507 to the inner side of the connector plate 920, keeping the wire harness and the connector plate relatively fixed. The wire harness moves synchronously during the insertion process to prevent the wire harness from shifting. The controller 10 is electrically connected to motor 1 601, motor 2 802, motor 3 808, motor 4 901, motor 5 907, drive cylinder 1 706, drive cylinder 2 916, clamping cylinder 1 806, and clamping cylinder 2 919. It can trigger the start and stop of each power element in sequence according to the preset process logic, accurately control the displacement and running sequence of each action, and realize the automated and continuous operation of the entire process of wire feeding, tensioning, guiding, alignment, insertion, and loading and unloading. No manual step-by-step operation intervention is required, which effectively improves the overall operation cycle stability and smoothness, and is suitable for the continuous operation requirements of mass production.

[0034] Working principle: First, the parameters are adjusted in advance. According to the outer dimensions of the amplifier board body 12 to be processed, the adjustment plate 605 is rotated to drive the threaded rod 606 to rotate synchronously, so that the two sets of limit plates 607 move relative to each other along the axial direction of the threaded rod. The spacing is adjusted to match the width of the board, ensuring that the stacked boards can be raised and lowered smoothly and the front and back positions are accurate. Then, the tension of the wire feeding assembly 5 is adjusted. The spring 508 pulls the adjustment rod 505 through its own elasticity, so that the guide wheel 506 maintains a moderate tension on the wire harness body 507, avoiding the wire harness from loosening and knotting or being damaged by excessive tension. The controller 10 presets the number of rotations of each motor, the extension and retraction stroke of each cylinder and the action sequence of the overall process. The moving wheel 11 at the bottom of the frame 1 can push the device to the corresponding work position on the production line. After locking the brake, it can enter the working state.

[0035] Entering the panel lifting and loading stage, the neatly stacked amplifier panel body 12 is placed above the lifting plate 604. Two sets of limiting plates 607 constrain the stacking position of the panels from the front and rear sides to prevent stacking deviation. The motor 601 is started, driving the drive rod 602 to rotate at a constant speed, driving the lifting plate 604 to lift vertically upward along the limiting rod 603, smoothly lifting the top panel to the picking height. The diagonally arranged loading and unloading components 7 are activated, and the moving block 704 moves horizontally along the drive rod 702 and the limiting rod 703 to directly above the panel. The drive cylinder 706 extends. The connecting frame 707 descends, and multiple suction rods 708 generate negative pressure suction force after contacting the top surface of the board, stably holding the board in place. Then, the drive cylinder 706 retracts, causing the board to rise. The moving block 704 moves horizontally to directly above the placement plate 13. The drive cylinder 706 extends again, and the suction rods 708 release the negative pressure, placing the board stably on the top surface of the placement plate 13. The placement plate 13 supports the bottom surface of the board, and the two side limiting plates 14 limit the side walls of the board from the left and right directions. Combined with the front and rear positioning of the board itself, the multi-directional precise fixing of the board is completed, providing a stable reference for subsequent insertion.

[0036] The process then proceeds to the wire harness feeding and guiding stage. The wire roller 501 rotates synchronously with the wire harness traction, continuously releasing the wire harness body 507. After being drawn from the wire roller, the wire harness first passes around the limiting rod 502 for initial guidance, then sequentially passes around the guide wheel 504 and guide wheel 506 to complete the change in conveying direction. The limiting plate 503 restricts the lateral movement of the wire harness from the side, preventing it from detaching from the guide wheels. The spring 508, in conjunction with the adjusting rod 505, provides the guide wheel 506 with elastic buffering capacity, absorbing tension fluctuations during the wire feeding process and maintaining the stability of the wire harness feeding. The wire harness then enters the moving assembly 8. After passing through the area, the wire harness passes between the drive wheel 809 and the limit wheel 810. The motor 808 drives the drive wheel 809 to rotate, and the wire harness is fed forward at a constant speed by the friction between the roller and the wire harness. The upper and lower limit wheels 812 clamp the wire harness vertically, restricting the wire harness from jumping up and down and ensuring that the wire harness always maintains a straight posture. The motor 802 can drive the moving block 804 to rise and fall through the drive rod 803. The clamping cylinder 806 clamps the end of the wire harness and adjusts the height position of the wire harness so that the end of the wire harness is accurately aligned with the wire inlet position of the plug plate 920, completing the pre-alignment and delivery of the wire harness.

[0037] Next, the precise alignment and insertion stage begins. The wiring assembly 9 first undergoes coarse alignment adjustment. Motor 4 901 starts, driving drive rod 5 902 to rotate, which in turn drives moving block 3 903 to move back and forth along slide rail 1 905, adjusting the front and back position of the wiring plate 920 so that the wire harness end aligns with the terminal holes on the board. Simultaneously, motor 5 907 starts, driving driven wheel 2 908 and belt 909 to rotate driven wheel 910 and drive rod 6 911, driving moving plate 912 to move horizontally along slide rail 2 914 towards the board, completing the coarse alignment before insertion. After coarse alignment, the fine insertion stage begins: clamping air… Cylinder 2 (919) clamps the end of the wire harness, driving cylinder 2 (916) to extend at a constant speed, pushing fixing plate 3 (917) forward smoothly along limiting rod 4 (918). Plug-in plate 920 moves forward synchronously with the wire harness, precisely inserting the end of the wire harness into the terminal hole of amplifier board body 12. Throughout the insertion process, the multi-stage slide rail and limiting rod structure ensure that the feeding action always runs in a straight line. The cylinder drive stably controls the magnitude of the insertion force and the insertion depth, avoiding excessive force that could damage the board pads, cause copper foil peeling or pin bending, and ensuring that the wire harness is inserted in place, stabilizing the contact resistance of the connection point and reducing the risk of overheating during operation.

[0038] After the insertion is completed, the unloading process begins. Clamping cylinder 2 919 releases the wire harness, driving cylinder 2 916 drives fixing plate 3 917 to retract and reset, motor 5 907 rotates in the opposite direction to drive moving plate 912 back to its initial position, motor 4 901 drives moving block 3 903 back to the standby position, and the unloading assembly 7 on the unloading side starts. The suction rod 708 picks up the inserted board from the placement plate 13 and moves it to the unloading station for stable placement. At the same time, lifting assembly 6 lifts another board to be processed, and the unloading assembly 7 on the loading side simultaneously completes the loading and positioning of the next board. The two sets of unloading assemblies 7 arranged diagonally work alternately to achieve seamless connection between loading and unloading, reducing the waiting time of the process. By repeating the above cycle, the insertion operation of multiple amplifier boards can be completed continuously.

[0039] The device, through its integrated structural layout and automated process coordination, enables the simultaneous insertion of multiple wire harnesses via a dual-sided insertion structure, significantly improving batch production efficiency. Multiple sets of guiding and limiting structures constrain the position of wire harnesses and boards throughout the entire process from feeding to insertion, ensuring insertion alignment accuracy. The stable driving method and adsorption-type loading and unloading effectively reduce the risk of damage to boards and wire harnesses, solving problems such as low accuracy, poor efficiency, easy damage, and poor process connection that exist in manual insertion.
