Detailed Implementation

[0016] like Figures 1 to 15As shown, in this embodiment, the multi-station correction platform of the present invention includes a carrier plate 1, on which sixteen concave acupoints 2 are provided. Each acupoint 2 includes a bottom surface 3 for supporting the product, an X-side reference surface 4 for correcting the product in the X direction, and a Y-side reference surface 5 for correcting the product in the Y direction. Each acupoint 2 also includes an X-direction correction space 6 opposite to the X-side reference surface 4 and a Y-direction correction space 7 opposite to the Y-side reference surface 5. The X-direction correction space 6 and the Y-direction correction space 7 are respectively provided with an X-direction push block structure 8 and a Y-direction push block structure 9. The platform also includes a mounting plate 10 disposed below the carrier plate 1. The mounting plate 10 is provided with an X-axis driving structure 11 and a Y-axis driving structure 12. The X-axis driving structure 11 simultaneously drives the X-axis pushing block structure 8 in each acupoint 2. The X-axis pushing block structure 8 causes the product in the acupoint 2 to abut against the X-side reference surface 4, thereby completing the X-side correction. The Y-axis driving structure 12 simultaneously drives the Y-axis pushing block structure 9 in each acupoint 2. The Y-axis pushing block structure 9 causes the product in the acupoint 2 to abut against the Y-side reference surface 5, thereby completing the Y-side correction.

[0017] In this embodiment, the carrier plate 1 integrates sixteen concave acupoints 2, which can simultaneously accommodate multiple products to be corrected, eliminating the need for individual operation on a single device, significantly improving the straightening and correction efficiency of batch parts, and adapting to standardized mass production scenarios. The bottom surface 3, X-side reference surface 4, and Y-side reference surface 5 within the acupoint 2 together constitute the three-dimensional positioning reference of the product, enabling rapid initial positioning of the product, avoiding product offset during correction, and ensuring the consistency of the correction reference. The X-direction correction space 6 and Y-direction correction space 7 provide the motion stroke for the X-direction push block structure 8 and Y-direction push block structure 9, respectively. The push block can smoothly push the product within the space, allowing the product to accurately conform to the X-side reference surface 4 and Y-side reference surface 5, completing precise alignment and correction in both X and Y directions, with stable and controllable correction accuracy. The mounting plate 10 serves as the mounting carrier for the X-direction drive structure 11 and Y-direction drive structure 12, realizing modular integration of drive components, making the equipment structure more compact and facilitating overall installation and maintenance. The X-axis drive structure 11 can simultaneously drive the X-axis push block structure 8 in all acupoints 2, and the Y-axis drive structure 12 synchronously drives all Y-axis push block structures 9. Only two sets of drive components are used to complete the synchronous correction of multiple stations, which greatly reduces the manufacturing cost and control complexity of the equipment, while ensuring that the correction actions of all stations are synchronized, and the straightening qualification rate can be stably maintained at a high level.

[0018] like Figure 8As shown, in this embodiment, the carrier plate 1 is provided with an X-direction groove 13, and sixteen acupoints 2 are symmetrically distributed on both sides of the X-direction groove 13, with six acupoints 2 on one side; the X-direction drive structure 11 includes an X-direction push rod 14 slidably connected to the X-direction groove 13, and the X-direction push rod 14 is provided with X-direction levers 15 corresponding one-to-one with the multiple X-direction push block structures 8; the X-direction drive structure 11 also includes an X-direction side push cylinder 16 that pushes the X-direction push rod 14 to move in the X direction; during operation, the X-direction side push cylinder 16 pushes the X-direction push rod 14 to move in the X direction, and the X-direction push rod 14 then drives the multiple X-direction levers 15 to simultaneously drive the X-direction push block structures 8, and the X-direction push block structures 8 make the product in the acupoint 2 adhere to the X-side reference surface 4, thereby completing the X-side correction.

[0019] In this embodiment, the X-axis groove 13 on the carrier plate 1 provides high-precision linear motion guidance for the X-axis push rod 14. Simultaneously, sixteen acupoints 2 are symmetrically distributed on both sides of the groove, making the workstation layout more compact and significantly improving space utilization. This allows for the simultaneous correction of 16 products at once. The X-axis push rod 14 directly slides into the X-axis groove 13, resulting in stronger lateral rigidity during movement. This effectively counteracts the eccentric load during push block operation, preventing the push rod from wobbling or jamming, and ensuring the straightness of long-stroke motion. Multiple sets of X-axis levers 15 on the X-axis push rod 14 correspond one-to-one with the X-axis push block structure 8. The linear motion of a single push rod can be synchronously converted into push block correction actions for all workstations. The power transmission path is short, with minimal loss, and the X-axis correction actions of all workstations are completely synchronized, without any asynchronous rhythm deviation. The X-axis side-push cylinder 16 serves as the power source and is a double-acting linear drive unit. Its bidirectional thrust is stable and controllable, and the pushing force and speed can be precisely controlled through air circuit adjustment to adapt to the correction force requirements of products made of different materials. Furthermore, its structure is simple and reliable, resulting in low maintenance costs. The entire X-axis drive structure 11 uses only one power source to complete the synchronous correction of 16 stations, significantly reducing the number of pneumatic components such as cylinders and control valves. This lowers equipment costs, simplifies the air circuit and control logic, and enhances the stability of equipment operation.

[0020] In this embodiment, the X-direction side-push cylinder 16 is disposed on the X-direction side of the mounting plate 10, and the telescopic rod 17 of the X-direction side-push cylinder 16 is located below the mounting plate 10. The X-direction sliding groove 13 and the mounting plate 10 are provided with interconnected through grooves 18. The telescopic rod 17 is provided with an X-direction connecting block 19. The lower end of the X-direction connecting block 19 is connected to the telescopic rod 17, and the upper end of the X-direction connecting block 19 passes through the through groove 18 and cooperates with the X-direction push rod 14.

[0021] In this embodiment, the X-direction side-push cylinder 16 is arranged on the X-direction side of the mounting plate 10, which makes full use of the unused side space of the mounting plate 10, avoids the cylinder occupying the working area above the carrier plate 1, makes the arrangement of the acupoints 2 on the carrier plate 1 more compact, and makes the overall size of the equipment smaller. The telescopic rod 17 is set below the mounting plate 10, which can hide the movement execution parts of the cylinder in the bottom space of the mounting plate 10, avoiding the safety hazards caused by exposed moving parts, reducing dust accumulation in the working area, and reducing the probability of component wear. The X-direction slide 13 and the through groove 18 on the mounting plate 10 provide a regular movement avoidance channel for the X-direction connecting block 19, which does not destroy the guiding integrity of the X-direction slide 13, and allows the bottom power to be smoothly transmitted to the X-direction push rod 14 above, making the structural layout simpler. The lower end of the X-axis connecting block 19 connects to the telescopic rod 17, and the upper end passes through the through slot 18 to connect to the X-axis push rod 14, realizing the vertical cross-layer transmission of power from the bottom cylinder to the top push rod. The transmission path is short and rigid, with less moment of inertia, faster dynamic response, no obvious backlash in power transmission, and more stable pushing accuracy. The entire power transmission structure is laid out entirely based on the layered space of the mounting plate 10, and all core moving parts are effectively protected, which reduces the risk of external interference to moving parts and makes the assembly, maintenance, and disassembly of the equipment more convenient. In this embodiment, an X-direction limiting adjustment screw 20, adapted to the end of the X-direction push rod 14, is provided on the other side of the mounting plate 10 in the X direction. The X-direction limiting adjustment screw 20 is in direct contact with the end of the X-direction push rod 14. The maximum stroke end point of the push rod 14 can be precisely set by the screwing depth, effectively preventing the push rod of the X-direction side push cylinder 16 from overshooting due to air pressure fluctuations or control delays, avoiding hard collisions between the push block structure 8 and the X-side reference surface 4, and protecting the long-term accuracy and lifespan of the precision reference surface and the push block. Different batches or models of products have slight tolerances in the X-direction dimensions. By turning the X-direction limiting adjustment screw 20, millimeter-level fine adjustments to the stroke of the push rod 14 can be achieved. This allows for adaptation to various product specifications without hardware replacement, significantly improving the flexible production capacity of the equipment and meeting the production needs of small batches and multiple varieties. The limit adjustment screw 20 adopts a precision thread structure, possessing excellent self-locking and vibration resistance, ensuring that the end position height of the push rod 14 is consistent in each correction cycle. This eliminates positioning drift caused by cylinder return error or mechanical elastic deformation, stabilizing the repeatability of multi-station correction within ±0.02mm. When cumulative errors or component wear occur after long-term operation, system calibration can be completed simply by rotating the X-axis limit adjustment screw 20 with a tool, without disassembling core components such as cylinders, push rods, or slides. This significantly reduces downtime for maintenance and improves the overall efficiency of equipment use.

[0022] like Figure 9As shown, in this embodiment, the Y-direction drive structure 12 includes a Y-direction push rod 20 slidably connected to the bottom surface of the mounting plate 10. Y-direction levers 21 are provided at both ends of the Y-direction push rod 20. Each Y-direction lever 21 has a lever 22 corresponding to one of the multiple Y-direction push block structures 9. A clearance groove 23 is provided in the Y-direction correction space 7 and on the mounting plate 10, and the lower end of each lever 22 is connected to the Y-direction lever 21. The upper end of each lever 22 passes through the clearance groove 23 and is connected to the Y-direction push block structure 9. In conjunction with the above, the Y-direction drive structure 12 also includes a Y-direction side push cylinder 24 disposed at the bottom of the mounting plate 10 to push the Y-direction push rod 20 to move in the Y direction; during operation, the Y-direction side push cylinder 24 pushes the Y-direction push rod 20 to move in the Y direction, the Y-direction push rod 20 then drives the Y-direction levers 21 at both ends, the Y-direction levers 21 then drive the levers 22 to simultaneously drive the Y-direction push block structure 9, the Y-direction push block structure 9 makes the product in the acupoint 2 adhere to the Y-side reference surface 5, thereby completing the Y-side correction.

[0023] In this embodiment, the Y-axis push rod 20 is directly slidably connected to the bottom surface of the mounting plate 10, so that the entire drive mechanism is completely hidden under the mounting plate 10, completely avoiding interference between the moving parts and the working area above the carrier plate 1, providing maximum spatial freedom for the dense arrangement of the acupoints 2, and further compressing the overall height of the equipment to meet the compact layout requirements of automated production lines. Each end of the Y-axis push rod 20 is provided with a set of Y-axis levers 21, forming a "center-driven, two-end-synchronized" transmission architecture, so that the Y-axis correction force is evenly transmitted to all the acupoints 2 on both sides of the carrier plate 1, effectively offsetting the torsional load that may be caused by unilateral drive, ensuring that the correction actions of the 16 stations in the Y-axis are completely synchronized without any rhythm deviation. The lower end of the lever 22 is rigidly connected to the Y-axis lever 21, and the upper end passes through the clearance groove 23 and directly cooperates with the Y-axis push block structure 9, realizing the vertical transmission of power from the bottom of the mounting plate 10 to the top of the carrier plate 1. This structure avoids the multi-stage transmission of traditional connecting rods or pins, resulting in a short transmission chain, high rigidity, and near-zero backlash, significantly improving Y-axis positioning accuracy and response speed. The interconnected clearance grooves 23 on the Y-axis correction space 7 and mounting plate 10 provide a closed motion channel for the push block 22, ensuring the continuity of the power transmission path, preventing foreign object intrusion and dust accumulation, extending the service life of the push block structure 9 and the push block 22, and reducing the frequency of lubrication and maintenance.

[0024] In this embodiment, a Y-side limiting block 25 is provided on the Y-direction push rod 20, and a Y-side limiting adjustment screw 26 adapted to the Y-side limiting block 25 is also provided at the bottom of the mounting plate 10. In this embodiment, the Y-side limiting block 25 is directly fixed to the end of the Y-direction push rod 20, serving as the physical endpoint sensing surface of the mechanical stroke, and forming a rigid contact limit with the Y-side limiting adjustment screw 26. This design avoids the electrical delay and wear risk of traditional external limit switches, achieving purely mechanical, zero-response-delay hard limit protection, effectively preventing the push rod of the Y-direction side push cylinder 24 from overshooting due to air pressure fluctuations or control signal lag, eliminating hard impact between the Y-direction push block structure 9 and the Y-side reference surface 5, and ensuring the long-term accuracy of the reference surface. The Y-side limiting adjustment screw 26 is installed at the bottom of the mounting plate 10, with its screw screwed in from bottom to top and pressing against the Y-side limiting block 25. The millimeter-level fine adjustment of the maximum stroke of the Y-direction push rod 20 is achieved by adjusting the screwing depth. This structure eliminates the need to disassemble the cylinder, push rod, or lever system; calibration can be completed using only a wrench, significantly improving the equipment's adaptability during production changes. The limit adjustment screw 26 employs a precision trapezoidal thread and locking nut structure, providing excellent self-locking and vibration resistance, ensuring consistent end-point height of the push rod 20 in each calibration cycle. Combined with the sliding design of the bottom surface of the Y-axis push rod 20 and the rigid transmission of the lever block 22, the system's repeatability can be stably controlled within ±0.015mm, meeting the calibration requirements of high-precision products such as precision electronic components and miniature hardware parts.

[0025] like Figures 10 to 12 As shown, in this embodiment, the X-axis push block structure 8 includes an X-axis push block base 27, an X-axis push block 28, and an X-axis limiting cover 29. The rear section of the X-axis push block 28 is slidably connected to the X-axis push block base 27, and the front section of the X-axis push block 28 protrudes from the side of the X-axis push block base 27. An X-axis return spring 30 is provided between the end of the rear section of the X-axis push block 28 and the X-axis push block base 27. A plurality of X-axis push block base positioning posts 31 are provided at the bottom of the X-axis push block base 27. An upper column 32 is provided on the X-axis push block 28. An X-axis elongated hole 33 is provided on the X-axis limiting cover 29. The X-axis limiting cover 29 is fixedly installed on the X-axis push block base 27. The upper column 32 passes through the X-axis elongated hole 33 and is connected to the X-axis lever 15. The X-axis push block base 27 is disposed in the X-axis correction space 6.

[0026] In this embodiment, the X-axis push block base 27 serves as the mounting base for the push block structure, fixed within the X-axis correction space 6, providing a stable support platform. Multiple X-axis push block base positioning posts 31 at its bottom can precisely engage with corresponding positioning holes on the carrier plate 1, achieving a repeatability accuracy of the push block structure 8 within the workstation of ≤±0.01mm. This ensures that the height of the correction force application point is consistent at each workstation, eliminating uneven correction caused by installation deviations. The rear section of the X-axis push block 28 is slidably connected to the base 27, while the front section is exposed on the side of the base, directly contacting the product sidewall to achieve direct transmission of the X-axis thrust. The sliding mating surface is precision ground, resulting in an extremely low coefficient of friction to prevent jamming. Its exposed front section allows the push block to rest against the X-side reference surface 4 without interference, ensuring that the correction contact surface is always parallel to the reference surface, improving the bonding quality. An X-axis return spring 30 is installed between the rear end of the X-axis push block 28 and the base 27. After the cylinder is depressurized, the push block 28 is automatically pulled back to its initial position, achieving non-contact reset. This design avoids the complexity of mechanical return mechanisms and reduces maintenance requirements. The spring preload is adjustable to adapt to the rebound characteristics of different product materials, preventing secondary displacement of the product due to residual stress during unloading. The X-axis limiting cover 29 is fixed above the base 27. The X-axis elongated hole 33 on it provides a unidirectional X-axis movement channel for the upper column 32, restricting the push block 28 to slide only along the X-axis and completely eliminating drift in the Y or Z directions. This structure achieves "single-degree-of-freedom rigid guidance," ensuring that the movement trajectory of the push block 28 is completely parallel to the X-side reference plane 4, with a correction direction accuracy within 0.01°. The upper column 32 connects the push block 28 and the X-axis lever 15, accurately transmitting external driving force from the lever 15 to the push block 28. Its structure, passing through the elongated hole 33, allows the push block 28 to retract freely during the reset process without affecting the continuous movement of the lever 15, achieving decoupling of the "drive-correction-reset" three stages and improving the system's dynamic response efficiency. This push block structure 8 is a modular unit; all components (base 27, push block 28, top cover 29, spring 30) can be disassembled and replaced as a whole without disassembling the carrier plate 1 or the slide 13. The positioning post 31 and the elongated hole 33 form a "positioning + guiding" dual calibration mechanism, allowing accuracy to be restored without re-adjustment after replacement, significantly shortening downtime for model changes.

[0027] like Figures 13 to 15As shown, in this embodiment, the Y-axis push block structure 9 includes a Y-axis push block base 34, a Y-axis push block 35, and a Y-axis limiting cover 36; the rear section of the Y-axis push block 35 is slidably connected to the Y-axis push block base 34, the front section of the Y-axis push block 35 protrudes from the side of the Y-axis push block base 34, a Y-axis return spring 37 is provided between the end of the rear section of the Y-axis push block 35 and the Y-axis push block base 34, and a plurality of Y-axis... The Y-axis push block base has a positioning post 38, a lower column 39 is provided below the Y-axis push block 35, and a Y-axis elongated hole 40 is provided at the bottom of the Y-axis push block base 34. The Y-axis limiting cover 36 is fixedly installed on the Y-axis push block base 34 to prevent the Y-axis push block 35 from falling off the Y-axis push block base 34. The lower column 39 passes through the Y-axis elongated hole 40 and is connected to the lever 22. The Y-axis push block base 34 is located in the Y-axis correction space 7.

[0028] In this embodiment, the Y-axis push block base 34 serves as the mounting base for the push block structure, fixed within the Y-axis correction space 7 to provide stable support. Multiple Y-axis push block base positioning posts 38 at its bottom can precisely engage with corresponding positioning holes on the carrier plate 1, achieving a repeatability positioning accuracy of the push block structure 9 ≤ ±0.01mm in each workstation. This ensures consistent height of the correction force application point at each workstation, eliminating uneven correction caused by installation deviations. The rear section of the Y-axis push block 35 is slidably connected to the base 34, while the front section is exposed on the side of the base, directly contacting the product sidewall to achieve direct transmission of the Y-axis thrust. The sliding mating surface is precision ground, resulting in an extremely low coefficient of friction to prevent jamming. Its exposed front section allows the push block to rest against the Y-side reference surface 5 without interference, ensuring the correction contact surface is always parallel to the reference surface and improving the bonding quality. A Y-axis return spring 37 is installed between the rear end of the Y-axis push block 35 and the base 34. After the cylinder is depressurized, the push block 35 is automatically pulled back to its initial position, achieving self-reset without pneumatic dependence. This design avoids the complexity of mechanical return mechanisms, reduces energy consumption and control logic burden; the spring preload is adjustable to adapt to the rebound characteristics of different product materials, preventing secondary displacement due to residual stress during unloading. The Y-axis limiting cover 36 is fixed above the Y-axis push block base 34, forming a top closed constraint, effectively preventing the Y-axis push block 35 from dislodging due to vibration or impact during high-frequency reciprocating motion, significantly improving system operational safety and long-term reliability, especially suitable for high-speed automated production line environments. The lower column 39 connects the Y-axis push block 35 and the external lever 22, and transmits power through the Y-axis elongated hole 40. This structure allows for slight lateral displacement compensation of the push block 35 during Y-axis movement, absorbing manufacturing tolerances and assembly errors, avoiding stress concentration caused by rigid impacts, extending the service life of the push block and the pusher block, and ensuring smooth and uninterrupted power transmission.

[0029] In this embodiment, support plates 41 are provided at both ends of the mounting plate 10 in the X direction, and a base plate 42 is provided at the lower end of the two support plates 41; a limit sensor 43 is provided on one of the support plates 41, and a limit piece 44 adapted to the limit sensor 43 is provided at the end of the Y-direction lever 21. A limit piece clearance hole 45 is provided on the support plate 41 on which the limit sensor 43 is provided. One end of the limit piece 44 is connected to the end of the Y-direction lever 21, and the other end of the limit piece 44 passes through the limit piece clearance hole 45 and cooperates with the limit sensor 43.

[0030] In this embodiment, the limit sensor 43 is mounted on the support plate 41, and achieves non-contact position detection by sensing the proximity of the limit piece 44. This design completely avoids the physical wear and bounce interference of traditional mechanical contacts, with a response speed of milliseconds, stable and reliable signal, and is suitable for industrial environments with high-frequency reciprocating motion, significantly improving the system control accuracy and lifespan. One end of the limit piece 44 is rigidly connected to the end of the Y-direction lever 21, and the other end passes through the limit piece clearance hole 45, forming a unidirectional motion channel. This structure ensures that the limit piece 44 is always aligned with the sensing surface of the sensor 43 during Y-direction movement, eliminating false triggering or missed triggering caused by lateral offset, achieving high coupling of "motion trajectory-sensing response", and a detection repeatability accuracy better than ±0.05mm. Support plates 41 are set at both ends of the mounting plate 10 in the X direction and connected by the base plate 42 to form a stable frame. The limit sensor 43 serves as the main control signal source, providing real-time feedback on whether the Y-direction lever 21 has reached the set endpoint, and is used for PLC closed-loop control, stop command triggering, and fault alarm. The Y-side limit adjustment screw 26 serves as the last physical line of defense, preventing overshoot accidents in case of sensor failure or control malfunction. This structure is completely hidden outside the mounting plate 10, does not occupy the Y-axis correction space 7, and forms an interference-free layout with the Y-axis lever 21, lever 22, and push block structure 9. The sensor 43 adopts an industrial-grade protective design, and the limit plate 44 can be made of stainless steel, which is resistant to oil and dust, and has a long maintenance cycle.

[0031] In this embodiment, the X-direction lever 15 is provided with an X-direction elongated slot 46, and the upper end of the upper column 32 is located in the X-direction elongated slot 46; the lever block 22 is provided with a Y-direction elongated slot 47, and the lower end of the lower column 39 is located in the Y-direction elongated slot 47.

[0032] In this embodiment, the X-direction elongated slot 46 provided on the X-direction lever 15 allows the upper end of the upper column 32 to slide freely within it along the X-direction. This structure allows the movement of the X-direction push block structure 8 to be entirely driven by the lever 15, without rigid coupling with the Y-direction drive system. When the Y-direction lever 21 drives the lever 22 to move, the lower column 39 slides within the Y-direction elongated slot 47, without applying lateral force to the X-direction lever 15, completely eliminating cross-interference between the X and Y axes, and ensuring that the dual-axis correction action is independent and without coupling deformation. The Y-direction elongated slot 47 provided on the lever 22 accommodates the lower end of the lower column 39 and allows it to slide along the Y-direction. This design allows the movement of the Y-axis push block structure 9 to be driven entirely by the push block 22, while the free sliding of the upper column 32 in the X-axis elongated slot 46 can absorb the slight displacement deviation of the X-axis push block structure 8 caused by product size tolerances or installation errors, thus avoiding the Y-axis drive system from bearing unexpected loads and improving the overall rigidity and stability of the system.

[0033] This "slot-column" structure constitutes a two-way flexible hinge: X-direction: The upper column 32 slides within the X-direction elongated slot 46 to compensate for the X-direction positioning error of multiple acupoints 2 on the carrier plate 1; Y direction: The lower column 39 slides in the Y-direction elongated slot 47 to compensate for the assembly gap between the Y-direction push block 35 and the Y-side reference surface 5.

[0034] The combined effect of these two technologies allows the system to adapt to workpiece dimensional fluctuations and cumulative assembly errors within the range of ±0.1mm, achieving synchronous mating at 16 stations without manual correction, significantly improving the yield rate. Traditional rigid connections are prone to internal stress due to asynchrony during multi-station synchronous motion, leading to push block deformation or spring fatigue. This invention achieves layered transmission with "rigid drive end and flexible actuator end" through slots: lever 15 and lever 22 form the rigid drive body, upper column 32 and lower column 39 form the flexible transmission bridge, and X-direction elongated slots 46 and Y-direction elongated slots 47 serve as stress relief channels. This structure significantly reduces peak stress in the transmission chain and extends the fatigue life of upper column 32, lower column 39, lever 15, and lever 22. Because the slot structure eliminates rigid interference, the system remains stable and shock-free during high-frequency reciprocating motion.

[0035] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
