Description

Technical Field

[0001] This invention relates to the field of profile processing equipment technology, specifically to a profile straightening-drilling integrated device and its control method based on vision recognition. Background Technology

[0002] After long metal profiles such as square tubes are extruded and rolled, they are generally subject to bending, twisting and other dimensional deviations due to factors such as residual stress, uneven cooling and bumps during transportation. Before drilling, the profiles usually need to be straightened to ensure the accuracy of subsequent drilling and the quality of assembly. The mainstream processing mode in the industry is split operation: the profiles are first sent to independent straightening equipment to be straightened, and after unloading and transportation, they are then loaded onto drilling equipment for drilling or punching.

[0003] However, currently, profile straightening and drilling processes are independent and operated on separate equipment. Profiles need to undergo unloading, cross-equipment transfer, and secondary clamping and positioning sequentially, resulting in a cumbersome overall process with low automation, significantly limiting overall processing efficiency. Furthermore, multiple clamping and positioning operations can easily lead to cumulative positioning errors, severely affecting the positional accuracy and processing consistency of profile drilling. Simultaneously, the separate equipment layout occupies a large area, requiring multiple operators to handle loading and unloading, material transfer, and equipment debugging, resulting in high labor input and production costs. Moreover, long profiles are prone to collisions and bending during frequent transfers, causing secondary deformation defects, further reducing the finished product's pass rate and product quality stability. To address these issues, the inventors propose a vision-recognition-based integrated profile straightening-drilling device and its control method to solve these problems. Summary of the Invention

[0004] To address the problems of existing profile straightening and drilling equipment that requires unloading, transporting, and secondary clamping of profiles, which is cumbersome and results in cumulative positioning errors due to multiple clamping operations, affecting drilling accuracy, and also the large footprint and high labor costs of separate equipment; furthermore, long profiles are prone to collisions and secondary deformation during transport, reducing the finished product qualification rate and processing stability; the purpose of this invention is to provide a profile straightening-drilling integrated device and its control method based on vision recognition.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a profile straightening-drilling integrated device based on visual recognition, comprising a straightening mechanism, a detection mechanism, and a drilling mechanism, wherein the straightening mechanism, the detection mechanism, and the drilling mechanism are arranged sequentially, and the drilling mechanism comprises a frame three, wherein a plurality of conveying rollers two are uniformly fixedly fixed at the middle of one end of the frame three, and a fixing rod is fixedly connected to one side of the other end of the frame three, wherein a control switch is fixedly connected to one end of the fixing rod, and two clamping plates are slidably engaged in the middle of the frame three, wherein guide pulleys are fixedly connected to both sides of the lower end of the two clamping plates, and a notch is opened on one side of the end of the two clamping plates, wherein a guide rod is fixedly connected to the inner wall of the notch, and a fixing plate is fixedly connected to the end of the two clamping plates. A groove is formed in the middle of one side of the fixed plate, and a connecting rod is slidably engaged in the middle of the groove. A positioning plate is fixedly connected to one end of the connecting rod. A slide plate is slidably engaged in one side of the fixed plate, and transmission rods are fixedly connected to both ends of the slide plate.

The guide pulleys are respectively slidably engaged in the middle of the corresponding sliding groove one, and the sliders are respectively slidably engaged in the middle of the corresponding sliding groove one. The sliding grooves one and two are arranged perpendicularly. One end of the drive rod is fixedly connected to a handle. The fixing plate is fixedly connected to the upper end of the frame three and is located at the end of the two clamping plates with notches. The two guide rods are respectively slidably engaged in the middle of the corresponding inclined sliding grooves. The rotating rod is located at the eccentricity of the turntable. One side of the turntable abuts against one side of the slide plate. The other end of the connecting rod is hinged to one end of the drive rod. When the connecting rod drives the drive rod to move, it will drive the rotating rod and the turntable to rotate. The eccentric rotation of the rod causes the turntable to no longer resist the slide plate. When the turntable rotates to its limit position, the drive rod will abut against the control switch, and the positioning plate will be fully engaged in the middle of the groove. A fixed frame is fixedly connected to the upper part of the middle of the frame three. Feed cylinders are fixedly connected to both sides of the middle of the fixed frame. The extension and retraction ends of the two feed cylinders pass through the fixed frame and are fixedly connected to the drilling machine. The two drilling machines are located directly above the middle of the two clamping plates. Two baffles are fixedly connected to the upper part of one end of the frame three. The two baffles are fixedly connected to each other. Multiple rotating shafts are evenly installed on the side of the two baffles that are close to each other. An inclined block is fixedly connected to one end of one of the baffles. The control switch is electrically connected to the feed cylinders and the drilling machine.

[0006] Preferably, the straightening mechanism includes a frame one, with multiple conveying rollers symmetrically mounted above and below the middle of the frame one. Each conveying roller has a driven tooth fixedly connected to one end through the side wall of the frame one. A straightening wheel is fixedly connected to the outer side of the middle of each conveying roller, and a positioning groove is formed in the middle of each straightening wheel. Two conveying rollers located on one side form a group, and the driven teeth at the ends of each group of two conveying rollers mesh with each other. Multiple driving teeth are fixedly mounted on one side of the frame one, respectively fixed in the middle of two adjacent groups of conveying rollers. The driving teeth mesh with two driven teeth located below the ends of the two groups of conveying rollers. A motor is fixedly mounted on one side of the frame one, and the output end of the motor is fixedly connected to one end of the driving teeth located in the middle. The detection mechanism includes a frame two, with a cover plate fixedly mounted above one end of the frame two. Multiple transverse conveying rollers are uniformly and symmetrically installed in the middle of the second frame. Multiple longitudinal conveying rollers are uniformly and symmetrically installed in the middle of one end of the second frame. Two industrial cameras are installed in the middle of the end of the second frame with a cover plate. The two industrial cameras are vertically distributed. The inclined block is located at the intersection of the second and third frames and is located on the side of the second frame with a discharge port. A feeding cylinder is fixedly connected to one side of the other end of the second frame. The feeding cylinder is electrically connected to the two industrial cameras. The telescopic end of the feeding cylinder passes through the side wall of the second frame and is fixedly connected to a limit push plate. A discharge port is opened in the middle of one side of the other end of the second frame. A receiving plate is fixedly connected to one side of the other end of the second frame. Limit plates are fixedly connected to both ends of the middle of the other side of the other end of the second frame. The two limit plates are distributed and abut against one side of the limit push plate. Under normal conditions, the limit push plate can play a guiding role.

[0007] A method for using a profile straightening-drilling integrated device based on visual recognition, comprising the following steps; S1. The square tube is fed into the straightening mechanism. The motor drives each set of conveying rollers to operate synchronously through gear meshing, which drives the square tube to be fed smoothly. Relying on the straightening wheel with positioning groove on the conveying roller, the bending and twisting deformation of the square tube is corrected by multi-directional extrusion, and the deviation of the square tube shape and position is corrected, providing a precise benchmark for subsequent processing. S2. After straightening, the square tube enters the inspection mechanism and is smoothly conveyed under the support of the transmission roller group. Two sets of vertically arranged industrial cameras collect the shape of the square tube to detect and judge the straightening quality. Unqualified square tubes can trigger the action of the feeding cylinder and be rejected through the discharge port. Qualified square tubes are smoothly fed into the punching mechanism through the inclined block with the assistance of the limiting guide structure. S3. The qualified square tube is conveyed to the drilling mechanism processing station by the second conveyor roller. After the square tube is in place against the positioning plate, it will be driven by the linkage structure of connecting rod, eccentric turntable and inclined slide to automatically clamp the self-locking square tube. After reaching the limit position, the control switch will be triggered to link the feed cylinder and the drilling machine to complete the precise drilling operation of the square tube. S4. After drilling is completed, the operator manually turns the handle, the linkage mechanism resets and releases the square tube self-locking limit of the clamping plate; after unlocking, the second conveyor roller sends out the processed square tube, the equipment resets and stands ready, and continues to process in a cycle. The matching standing groove facilitates the removal of workpieces and the debugging and maintenance of the equipment.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention integrates straightening, visual inspection and sorting, and drilling into one unit, enabling continuous integrated processing of square tubes. The drilling station adopts a mechanical linkage self-locking structure. After the square tube is delivered to the position, the clamping plate can be automatically clamped and positioned by the square tube feed thrust. The drilling is started by touching the control switch at the same time as the tube is in position. The overall mechanical structure is compact, reducing electrical control components and resulting in a low failure rate.

[0009] 2. This invention uses a dual-view industrial camera to detect the straightness and torsion of square tubes through a testing mechanism. Unqualified square tubes can be automatically pushed out and rejected by the feeding cylinder, avoiding defective products from flowing into the drilling station and causing invalid processing. The processing flow is continuous and the production efficiency is high.

[0010] 3. In this invention, the self-locking structure is equipped with orthogonally arranged sliding grooves to guide and constrain the clamping plate and sliding plate, ensuring smooth movement and preventing jamming. After drilling is completed, the handle is used for manual unlocking. At the same time, a worker standing groove is provided to facilitate equipment debugging, maintenance and workpiece unloading operations. The positioning and clamping accuracy is high, and the equipment maintenance and operation are convenient. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example: Figure 1-10As shown, the present invention provides a technical solution: a profile straightening-drilling integrated device based on visual recognition, including a straightening mechanism 1, a detection mechanism 2, and a drilling mechanism 3. The straightening mechanism 1, the detection mechanism 2, and the drilling mechanism 3 are arranged sequentially. The drilling mechanism 3 includes a frame 301. A plurality of conveying rollers 306 are uniformly fixed to the middle of one end of the frame 301. A fixing rod 3013 is fixed to one side of the other end of the frame 301. A control switch 3014 is fixed to one end of the fixing rod 3013. Two clamping plates 3015 are slidably engaged in the middle of the frame 301. Guide pulleys 3018 are fixed to both sides of the lower end of the two clamping plates 3015. A notch 3016 is opened on one side of the end of each of the two clamping plates 3015. A guide rod 3017 is fixed to the inner wall of each notch 3016. A fixing plate 3023 is fixed to the end of each of the two clamping plates 3015. A groove 3024 is provided in the middle of one side of the fixed plate 3023. A connecting rod 3025 is slidably engaged in the middle of the groove 3024. A positioning plate 3026 is fixedly connected to one end of the connecting rod 3025. A slide plate 3019 is slidably engaged in one side of the fixed plate 3023. A transmission rod 3020 is fixedly connected to both ends of the slide plate 3019. A slider 3022 is fixedly connected to both sides of the lower end of the slide plate 3019. An inclined groove 3021 is provided on the surface of one end of each of the two transmission rods 3020. A return spring 3027 is fixedly provided between the two ends of the other side of the fixed plate 3023 and the two sides of the middle of the slide plate 3019. A rotating rod 3029 is rotatably installed on one side of the slide plate 3019. A turntable 3028 is fixedly connected to the outer side of the lower end of the rotating rod 3029. A drive rod 3030 is fixedly connected to one side of the upper end of the rotating rod 3029. Drilling machines 309 are provided on both sides of the middle of the upper end of the frame 301. By adopting the above technical solution, the overall equipment is arranged in three sections: straightening, inspection, and drilling, to realize the integrated continuous processing of square tube straightening, quality inspection, and drilling. When the drilling mechanism 3 is working, the conveying roller 306 rotates continuously, conveying the square tube that has been straightened and inspected by the previous process to the processing station. When the end of the square tube contacts the positioning plate 3026 and reaches the limit processing position, the axial conveying power of the conveying roller will be automatically released. Simultaneously, the square tube pushes the positioning plate 3026, causing the connecting rod 3025 to slide along the inside of the groove 3024, and the linkage slide plate 3019 compresses the return spring 3027, causing displacement. The slide plate 3019 drives the transmission rods 3020 at both ends to move synchronously. Utilizing the oblique guide cooperation between the inclined slide groove 3021 and the guide rod 3017, the two sets of clamping plates 3015 are driven to slide synchronously towards each other along the sliding groove 3011 with the help of the guide pulleys 3018, achieving automatic clamping and self-locking of the square tube. When the square tube is in place, the control switch 3014 is triggered, starting the drilling machine 309 to complete the drilling operation. After the drilling operation is completed, the drive rod 3030 is manually rotated in the reverse direction, causing the rotating rod 3029 and the turntable 3028 to reset in linkage, releasing the self-locking limit of the clamping plate 3015 on the square tube, and completing a single drilling cycle.

[0016] A worker standing slot 302 is provided on one side of the other end of the frame 301. Two sets of sliding slots 3011 are symmetrically provided on both sides of the middle of the other end of the frame 301. Two sliding slots 3012 are symmetrically provided on the other end of the frame 301. Guide pulleys 3018 are respectively slidably engaged in the middle of the corresponding sliding slot 3011. Sliding blocks 3022 are respectively slidably engaged in the middle of the corresponding sliding slot 3011. Sliding slots 3011 and sliding slots 3012 are arranged vertically. By adopting the above technical solution, the worker standing slot 302 opened on the frame 301 provides a standing operating space for the operator. The sliding slot 1 3011 and sliding slot 2 3012 opened at the end of the frame 301 are arranged perpendicularly to each other to form an orthogonal limiting guide structure. The clamping plate 3015 is slidably engaged with the sliding slot 1 3011 through the guide pulley 3018, and the sliding plate 3019 is also slidably engaged with the sliding slot 1 3011 through the slider 3022. This strictly constrains the movement trajectory of the clamping plate 3015 and the sliding plate 3019, effectively limiting the deviation, skewness and jamming of each moving part during the operation, ensuring the smooth self-locking clamping action of the clamping plate, and further improving the positioning accuracy of the square tube and the overall operation stability of the equipment.

[0017] One end of the drive rod 3030 is fixedly connected to a handle 3031. The fixed plate 3023 is fixedly connected to the upper end of the frame 301 and is located at the end of the two clamping plates 3015 with notches 3016. The two guide rods 3017 are respectively slidably engaged in the middle of the corresponding inclined slide grooves 3021. The rotating rod 3029 is located at the eccentricity of the turntable 3028. One side of the turntable 3028 abuts against one side of the slide plate 3019. The other end of the connecting rod 3025 is hinged to one end of the drive rod 3030.

[0018] By adopting the above technical solution, the fixing plate 3023 is fixedly installed on the upper end of the frame 301, providing a stable installation benchmark for the overall self-locking linkage mechanism. The guide rod 3017 is slidably engaged inside the inclined slide groove 3021, forming an inclined sliding fit structure. Utilizing the inclined transmission principle, the power conversion from the horizontal sliding of the slide plate 3019 to the vertical clamping movement of the clamping plate 3015 is realized, ensuring that the clamping plates 3015 on both sides are synchronously aligned and clamped, achieving stable self-locking of the square tube. The turntable 3028 is eccentrically set... Rod 3029 abuts against the side wall of slide plate 3019, while connecting rod 3025 is hinged to drive rod 3030. Together with end handle 3031, they form a manual unlocking structure. After drilling is completed, the operator can rotate drive rod 3030 through handle 3031 to drive turntable 3028 to rotate eccentrically, push slide plate 3019 to slide and reset, release the squeezing limit of inclined slide groove 3021 on guide rod 3017, and loosen the square tube of clamping plates 3015 on both sides, thus completing the workpiece unloading preparation.

[0019] When the connecting rod 3025 drives the drive rod 3030 to move, it will cause the rotating rod 3029 and the turntable 3028 to rotate eccentrically around the rotating rod 3029, so that the turntable 3028 can no longer resist the slide plate 3019. When the turntable 3028 rotates to the limit position, the drive rod 3030 will abut against the control switch 3014, and the positioning plate 3026 will be fully engaged in the middle of the groove 3024.

[0020] By adopting the above technical solution, when the square tube feeds and pushes the positioning plate 3026, it can drive the connecting rod 3025 to slide along the groove 3024, thereby pulling the drive rod 3030 to move synchronously. During the movement of the drive rod 3030, it drives the rotating rod 3029 and the turntable 3028 to rotate eccentrically as a whole, so that the turntable 3028, which was originally against the side wall of the slide plate 3019, gradually gets off the resistance limit, releases the constraint on the slide plate 3019, and allows the slide plate 3019 to slide smoothly and cooperate with the inclined slide groove 3021 and the guide rod 3017 to complete the clamping and self-locking action of the clamping plate 3015. When the turntable 3028 rotates to the limit position, the positioning plate 3026 is completely retracted and locked in the middle of the groove 3024, realizing the mechanical structure to be in place and limited. At the same time, the end of the drive rod 3030 precisely presses against the control switch 3014, triggering the drilling start signal.

[0021] A fixed frame 307 is fixedly connected to the upper part of the middle of the frame 301. Feed cylinders 308 are fixedly connected to both sides of the middle of the fixed frame 307. The telescopic ends of the two feed cylinders 308 pass through the fixed frame 307 and are fixedly connected to the drilling machine 309. The two drilling machines 309 are located directly above the middle of the two ends of the clamping plates 3015. Two baffles 303 are fixedly connected to the upper part of one end of the frame 301. The two baffles 303 are fixedly connected to each other. Multiple rotating shafts 305 are evenly installed on the side of the two baffles 303 that are close to each other. An inclined block 304 is fixedly connected to one end of one of the baffles 303. The control switch 3014 is electrically connected to the feed cylinders 308 and the drilling machine 309.

[0022] By adopting the above technical solution, a fixed frame 307 is fixedly installed on the upper end of the frame 301, providing a stable mounting carrier for the feed cylinder 308 and the drilling machine 309. The feed cylinder 308 is installed through the fixed frame 307 and its telescopic end is fixedly connected to the drilling machine 309, which can accurately drive the drilling machine 309 to feed vertically to complete the drilling operation. The two sets of drilling machines 309 are arranged directly above the clamping area of ​​the two sets of clamping plates 3015, which can align with the preset drilling position of the square tube and ensure the drilling alignment accuracy. The two sets of baffles 303 set at the feed end of the frame 301 are fixedly connected to each other as an integral structure. Rotatable shafts 305 are evenly distributed throughout the space to provide lateral limiting and guiding for the square tube feeding, preventing left and right deviations and skew during the square tube conveying process, and ensuring that the square tube enters the positioning and clamping station smoothly. The inclined block 304 can guide and correct the feeding square tube, further improving the feeding smoothness. The control switch 3014 is electrically linked to the feed cylinder 308 and the drilling machine 309 respectively. When the mechanical linkage structure completes the square tube self-locking and triggers the control switch 3014, the feed cylinder 308 and the drilling machine 309 can be automatically started to perform the drilling process, realizing the linkage operation of positioning, clamping and drilling.

[0023] The straightening mechanism 1 includes a frame 101. Multiple conveying rollers 102 are symmetrically installed above and below the middle of the frame 101. One end of each conveying roller 102 passes through the side wall of the frame 101 and is fixedly connected to a driven tooth 105. A straightening wheel 103 is fixedly connected to the outer side of the middle of each conveying roller 102. A positioning groove 104 is opened in the middle of each straightening wheel 103. Each pair of conveying rollers 102 located on one side forms a group.

[0024] By adopting the above technical solution, the frame 101 serves as the load-bearing base of the straightening mechanism, providing a stable installation support foundation for each straightening and conveying component. Multiple sets of conveying rollers 102 are symmetrically arranged on the frame 101, forming an upper and lower clamping conveying structure for the square tube, ensuring the stability of the square tube feeding process. The driven teeth 105 at the ends of the conveying rollers 102 can cooperate with the external transmission structure to achieve synchronous transmission, ensuring that the rotation speed of each conveying roller 102 is uniform. Straightening wheels 103 are fixedly installed on the outer side of each conveying roller 102, and the straightening wheels 103 have a positioning groove 104 in the middle, which can accurately engage with the outer wall of the square tube profile and limit the profile. The straightening wheels 103 arranged vertically can squeeze and straighten the bent and twisted square tube from multiple directions. With the grouped arrangement of the conveying rollers 102, segmented continuous straightening operation is realized, effectively correcting the shape and position deviation of the square tube and ensuring the processing benchmark accuracy of subsequent inspection and drilling processes.

[0025] The driven teeth 105 at the ends of the conveyor rollers 102, which are in pairs, mesh with each other. A plurality of driving teeth 106 are fixed on one side of the frame 101. The driving teeth 106 are respectively fixed in the middle of two adjacent sets of conveyor rollers 102. The driving teeth 106 mesh with the two driven teeth 105 at the lower ends of the two sets of conveyor rollers 102. A motor 107 is fixedly connected to one side of the frame 101. The output end of the motor 107 is fixedly connected to one end of the driving teeth 106 located in the middle.

[0026] By adopting the above technical solution, the frame 101 serves as the load-bearing base of the straightening mechanism, providing a stable installation support foundation for each straightening, conveying, and transmission component. Multiple sets of conveyor rollers 102 are symmetrically installed vertically in the middle of the frame 101, with each pair of conveyor rollers 102 forming a group. The driven teeth 105 at the ends of each group of conveyor rollers 102 mesh with each other, achieving synchronous linkage within the same group. Multiple driving teeth 106 are mounted on one side of the frame 101, each driving tooth 106 correspondingly arranged between two adjacent groups of conveyor rollers 102, meshing with the driven teeth 105 below the two groups of conveyor rollers 102 for transmission. A motor 107 installed on the side of the frame 101 serves as the power source, its output end fixedly connected to the driving teeth 106 in the middle. The driving teeth 106 can drive each group of driven teeth 105 step by step, achieving synchronous rotation of all conveyor rollers 102. The transmission structure is compact and has high transmission consistency. A straightening wheel 103 is fixedly installed on the outer side of each conveying roller 102. The positioning groove 104 opened in the middle of the straightening wheel 103 can accurately engage with the outer wall of the square tube to achieve profile limiting constraint. The straightening wheels 103 arranged symmetrically on the upper and lower sides can continuously squeeze and correct the bent and twisted square tube from multiple directions, effectively correct the shape and position deviation of the square tube, ensure the stability of the square tube conveying and feeding, and provide a precise processing benchmark for subsequent inspection and drilling processes.

[0027] The testing mechanism 2 includes a frame 201. A cover plate 205 is fixedly connected to the top of one end of the frame 201. Multiple transverse transmission rollers 202 are evenly and symmetrically installed in the middle of the frame 201. Multiple longitudinal transmission rollers 203 are evenly and symmetrically installed in the middle of one end of the frame 201. Two industrial cameras 204 are provided in the middle of the end of the frame 201 where the cover plate 205 is installed. The two industrial cameras 204 are vertically distributed. The inclined block 304 is located at the intersection of the frame 201 and the frame 301 and is located on the side of the frame 201 where the discharge port 206 is opened. By adopting the above technical solution, the second frame 201 serves as the supporting foundation of the inspection mechanism, ensuring the stable installation of each transmission component and inspection component. The horizontal transmission rollers 202 evenly and symmetrically arranged in the middle of the second frame 201 and the vertical transmission rollers 203 arranged at the end cooperate with each other to form a multi-directional support and conveying structure for the square tube, effectively ensuring that the square tube is fed smoothly and straight after the straightening process, providing stable feeding conditions for visual inspection. The cover plate 205 is set at the upper end of the second frame 201 to reduce external stray light interference and optimize the inspection environment. Two sets of vertically distributed industrial cameras 204 are arranged at the end of the second frame 201, which can collect the shape of the straightened square tube from different dimensions, accurately detect the straightness, torsion and other form and position parameters of the square tube, and complete the straightening quality judgment. The inclined block 304 is arranged at the junction of the second frame 201 and the third frame 301 and on the side of the discharge port 206, which can smoothly guide and convey qualified square tubes to the drilling mechanism, and at the same time provide a structural adaptation foundation for the discharge operation of unqualified profiles.

[0028] A feeding cylinder 208 is fixedly connected to one side of the other end of the frame 201. The feeding cylinder 208 is electrically connected to two industrial cameras 204. The telescopic end of the feeding cylinder 208 passes through the side wall of the frame 201 and is fixedly connected to a limiting push plate 209. A discharge port 206 is opened in the middle of one side of the other end of the frame 201. A receiving plate 207 is fixedly connected to one side of the other end of the frame 201. Limiting plates 2010 are fixedly connected to both ends of the middle of the other side of the other end of the frame 201. The two limiting plates 2010 abut against one side of the limiting push plate 209 respectively. Under normal conditions, the limiting push plate 209 can play a guiding role.

[0029] By adopting the above technical solution, the feeding cylinder 208 is electrically connected to two industrial cameras 204, receiving detection signals from the industrial cameras 204 to achieve sorting action; the extension end of the feeding cylinder 208 drives the limit push plate 209 to reciprocate; a discharge port 206 is opened on the second frame 201, and a receiving plate 207 is set on the outside of the discharge port 206; when the industrial camera 204 detects that the square tube is not straightened, the feeding cylinder 208 extends, driving the limit push plate 209 to discharge the unqualified square tube from the discharge port 206. Unqualified square tubes are unloaded via receiving plate 207 to prevent them from entering the drilling mechanism and causing ineffective processing. Two limiting plates 2010 abut against the side of limiting push plate 209 to laterally limit push plate 209 and prevent it from swaying during operation. Under normal conditions, the feeding cylinder 208 is in the retracted state, and the limiting push plate 209 is constrained by the limiting plate 2010 to maintain a fixed position, which can provide lateral guidance and limiting effect for the conveyed square tubes, ensuring that qualified square tubes can be smoothly conveyed to the drilling mechanism.

[0030] A method for using a vision recognition-based profile straightening-drilling integrated device includes the following steps; S1. The square tube is fed into the straightening mechanism 1. The motor 107 drives each set of conveying rollers 102 to operate synchronously through gear meshing, which drives the square tube to feed smoothly. Relying on the straightening wheel 103 with positioning groove 104 on the conveying roller 102, the bending and twisting deformation of the square tube is corrected by multi-directional extrusion, and the deviation of the square tube shape and position is corrected, providing a precise benchmark for subsequent processing. S2. The straightened square tube enters the inspection mechanism 2 and is smoothly conveyed under the support of the transmission roller group. Two sets of vertically arranged industrial cameras 204 collect the shape of the square tube to detect and judge the straightening quality. Unqualified square tubes can trigger the action of the feeding cylinder 208 and be rejected through the discharge port 206. Qualified square tubes are smoothly fed into the punching mechanism 3 through the inclined block 304 with the assistance of the limiting guide structure. S3. The qualified square tube is conveyed to the processing station of the drilling mechanism 3 by the second conveyor roller 306. After the square tube is in place against the positioning plate 3026, it will be driven by the linkage structure of the connecting rod 3025, the eccentric turntable 3028, and the inclined slide 3021 to drive the clamping plate 3015 to automatically clamp the self-locking square tube. After reaching the limit position, the control switch 3014 will be triggered to link the feed cylinder 308 and the drilling machine 309 to complete the precise drilling operation of the square tube. S4. After drilling is completed, the operator manually turns handle 3031, the linkage mechanism resets and releases the square tube self-locking limit of clamp 3015; after unlocking, conveyor roller 2 306 sends out the processed square tube, the equipment resets and stands ready, and continues to process in a cycle. The matching standing groove facilitates the removal of workpieces and the debugging and maintenance of the equipment.

[0031] Working principle: The device is composed of a straightening mechanism 1, an inspection mechanism 2, and a drilling mechanism 3, which are assembled sequentially along the feed direction. It can complete the entire process of square tube extrusion straightening, straightening quality visual inspection and sorting, and qualified square tube positioning and self-locking drilling in sequence.

[0032] During processing, the square tube is fed into the straightening mechanism 1. The motor 107 outputs power to drive the central active gear 106 to rotate. The active gear 106 meshes and drives each set of driven gears 105 to rotate. Each pair of conveyor rollers 102 forms a group. The conveyor rollers 102 in the same group rotate synchronously by meshing with each other through the driven gears 105, driving the square tube forward. The straightening rollers 103 on the conveyor rollers 102 engage with the outer wall of the square tube using the positioning grooves 104. Multiple sets of straightening rollers 103 squeeze the square tube from multiple directions, continuously straightening the bent and twisted square tube. After straightening, the square tube is conveyed into the inspection mechanism 2. After entering the inspection mechanism 2, the square tube is fed smoothly under the support of the transverse conveyor rollers 202 and the longitudinal conveyor rollers 203. The cover plate 205 on the top of the frame 201 blocks external light. Two sets of vertically arranged industrial cameras 204 collect images of the square tube's shape, detect the straightness and twist of the square tube, and determine whether the straightening is qualified. If the square tube fails the straightening test, the industrial camera 204 outputs a signal to activate the unloading cylinder 208. The unloading cylinder 208 extends and pushes the limiting push plate 209, pushing the unqualified square tube out of the discharge port 206. The square tube slides down to the receiving plate 207 to complete rework and unloading. The limiting plate 2010 laterally limits the limiting push plate 209 to prevent the push plate from swinging. If the square tube passes the straightening test, the unloading cylinder 208 remains retracted, and the limiting push plate 209 is in the guide position to laterally limit the square tube. The qualified square tube is guided by the inclined block 304 and smoothly fed into the drilling mechanism 3.

[0033] The qualified square tubes will enter the subsequent punching mechanism 3, and be conveyed forward under the continuous rotation drive of the second conveyor roller 306. The baffle 303 and the rotating shaft 305 limit the lateral movement of the square tubes to prevent skewed conveying. When the end of the square tube abuts against the positioning plate 3026 and reaches the limit processing position, the feed of the square tube is blocked, and the axial pushing force of the second conveyor roller 306 is automatically released, so that no hard pushing force is generated on the positioning self-locking structure. The square tube pushes the positioning plate 3026, causing the connecting rod 3025 to slide along the groove 3024 of the fixed plate 3023. The connecting rod 3025 pulls the drive rod 3030 to move. The drive rod 3030 drives the rotating rod 3029 and the turntable 3028 to rotate eccentrically. The turntable 3028 is released from the constraint of the side wall of the slide plate 3019. Under the action of the mechanism transmission, the slide plate 3019 compresses the return spring 3027 and is displaced. The slide plate 3019 drives the transmission rods 3020 on both sides to move. Relying on the oblique transmission cooperation of the inclined slide groove 3021 and the guide rod 3017, the two clamping plates 3015 are driven to slide towards each other along the sliding groove 3011 with the help of the guide pulley 3018, so as to realize the lateral automatic clamping and self-locking position of the square tube. When the turntable 3028 rotates to its limit position, the positioning plate 3026 is fully retracted into the groove 3024 to achieve mechanical limiting. At the same time, the end of the drive rod 3030 presses against the control switch 3014. The control switch 3014 is triggered, which links the feed cylinder 308 and the drilling machine 309 to work. The feed cylinder 308 drives the drilling machine 309 to feed downwards and perform drilling operations on the square tube that has been locked and positioned.

[0034] After the drilling process is completed, the operator can manually turn the handle 3031 to drive the drive rod 3030, rotating rod 3029, and turntable 3028 to rotate eccentrically. The turntable 3028 pushes the sliding plate 3019 back to slide and reset. The inclined slide groove 3021 releases the pressure on the guide rod 3017, the clamping plates 3015 separate, and the self-locking limit of the square tube is released, completing a single processing cycle. The subsequent conveying roller 306 continues to rotate, sending out the processed square tube, waiting for the next square tube to be fed for processing. Among them, the sliding groove 3011 and the sliding groove 3012 are orthogonally arranged to constrain the sliding trajectory of the clamping plate 3015 and the sliding plate 3019, preventing the moving parts from deviating and jamming. The worker standing groove 302 facilitates the operator to manually unlock, debug, and maintain the equipment.

[0035] In this device, the electrical connection between the industrial camera 204 and the unloading cylinder 208, and the electrical linkage control between the control switch 3014 and the feed cylinder 308 and the drilling machine 309, are all existing technologies. The entire machine is equipped with a PLC controller. The industrial camera 204 transmits the collected square tube shape detection signal to the PLC. The PLC outputs a signal based on the detection result to control the solenoid valve of the unloading cylinder 208, enabling the automatic discharge of defective square tubes. The control switch 3014 is a mechanical limit switch. After the square tube mechanically locks into position and touches the control switch 3014, it sends a position signal back to the PLC. The PLC then outputs control signals to drive the feed cylinder 308 and the drilling machine 309 to perform the drilling action. The above-mentioned electrical control methods for signal acquisition, logic judgment, and solenoid valve driving are well-known technologies in the field, and the electrical control program will not be described in detail here.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
