Abstract

This invention discloses a fully automated metal parts processing device based on visual monitoring, relating to the field of metal parts processing technology. It includes an automatic grinding assembly, with a visual monitoring component and a correction component respectively mounted on the top of the automatic grinding assembly. In use, during the intermittent conveying of the part shaft by an intermittent turntable, a visual camera acquires images. When the elastic silicone sheet is detected to bend or deform, the control system determines that the part shaft's posture is abnormal. It then activates forward and reverse motors, driving the fixed block, correction plate, and correction block to rotate. Under the action of the correction groove, a thrust is applied to the movable wheel and moving rod, causing the two correction plates to move relative to each other, pushing the offset part shaft to a centered position, thereby achieving posture correction. The part shaft is guided by the guide frame, maintaining its centered position during grinding, realizing automated double-end face grinding.

Description

Technical Field

[0001] This invention relates to the field of metal parts processing technology, specifically to a fully automated metal parts processing device based on vision monitoring. Background Technology

[0002] Metal fittings refer to parts with specific shapes and functions made from metal materials through processing techniques such as casting, forging, cutting, stamping, and welding. They are widely used in machinery manufacturing, automobiles, aerospace, and electronics, serving as the basic units constituting various equipment and devices. In the metal fitting manufacturing process, burrs or tool marks may remain on the end faces of the fittings due to previous processing steps. Grinding on a grinding machine not only yields a smooth and clean surface but also corrects dimensional and positional errors such as roundness, cylindricity, and flatness.

[0003] In existing technologies, double-end face grinders can complete the grinding of both end faces of metal parts in one pass, significantly improving processing efficiency. Double-end face grinders typically have a protective plate on top of the feed turntable. After the feeding system transports the metal part shaft to be processed onto the turntable, the protective plate protects the shaft along the feeding path, preventing accidental drops and potential equipment jamming. However, during the feeding process, if the metal part shaft experiences unstable force and positional deviation, the protective plate cannot adjust the shaft. This results in a shaft with an abnormal posture being transported to the grinding zone for grinding, easily causing uneven processing of the two end faces, a sharp increase in parallelism error, decreased processing quality, and further damage to the grinding tools.

[0004] Therefore, we propose a fully automated metal parts processing device based on visual monitoring to solve the problems mentioned in the background art. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In use, during the intermittent conveying of the accessory shaft by the intermittent turntable, a vision camera acquires images. When the elastic silicone sheet is detected to bend and deform, the control system determines that the accessory shaft's posture is abnormal. It then activates the forward and reverse motors, driving the fixed block, correction plate, and correction block to rotate. Under the action of the correction groove, a thrust is applied to the movable wheel and moving rod, causing the two correction plates to move relative to each other, pushing the offset accessory shaft to the center position, thus achieving posture correction. The shaft then enters the guide frame, where it is guided to prevent further offset. The vision monitoring component monitors the accessory shaft's posture and position in real time, and in conjunction with the control system, intelligently triggers the correction component to correct the shaft. Finally, guided by the path of the guide frame, the accessory shaft remains in the center position for grinding, achieving automated double-end surface grinding.

[0020] 2. In use, the reference marker is fixed and serves as a baseline positioning component. It works in conjunction with a deformable elastic silicone sheet to form a "deformation comparison reference." The vision camera only needs to compare the parallelism between the elastic silicone sheet and the reference marker to determine whether the component shaft has shifted, simplifying the visual recognition logic. The first and second reference markers are red and blue, respectively. By collecting the positional changes of the second reference marker, the offset of the component shaft can also be determined, avoiding the influence of light on the recognition of the elastic silicone sheet's contour, which could lead to monitoring failure and improve the accuracy of the visual monitoring results.

[0021] 3. In use, pulling the rotating block moves the connecting rod, the convex rod disc, and the annular plate upwards, causing the convex rod disc to engage with the concave toothed ring. The annular plate moves the insert rod into the arc-shaped groove. Then, rotating the rotating block causes the convex rod disc to rotate the concave toothed ring, which in turn causes one end of the H-shaped clamping plate to rotate out of the slot. Repeating the above operation, one end of multiple H-shaped clamping plates is rotated out in sequence. Then, the limiting screw is unscrewed, which lifts the correction block from the mounting slot, allowing for quick replacement of correction blocks with different specifications of correction slots, facilitating the correction of accessory shafts of different widths.

The outer surface of the correction frame 301 is provided with a guide frame 316. The two correction plates 317 are fixedly connected to the opposite side of each other with elastic pads 313. The outer surfaces of both sides of the two correction blocks 306 are provided with slots 318. The inside of the correction disc 304 is provided with four embedded slots 319. The bottom surface of the inside of the four embedded slots 319 is provided with a recessed groove 320. The inside of the correction disc 304 is provided with movable slots 321 near the four embedded slots 319. The bottom surface of the inside of the four movable slots 321 is provided with two arc-shaped slots 322. Each of the two movable rods 308 has a movable wheel 309 movably fitted at its top end. The outer surfaces of the two movable wheels 309 are respectively movably embedded inside the two correction grooves 307. Each of the two movable rods 308 has a limit screw 310 threaded into its top end. Two support slip rings 311 are fixedly installed on the outer surfaces of each of the two movable rods 308. Two support rods 312 are fixedly installed inside the correction frame 301. Four support slip rings 311 are respectively movably fitted on the outer surfaces of the two support rods 312. First mounting brackets 314 are fixedly installed on the front and rear surfaces of the correction frame 301. Second mounting brackets 315 are fixedly installed on one side of the outer surface of each of the two first mounting brackets 314. The front and rear surfaces of the monitoring frame 201 are respectively bolted to the edges of the two second mounting brackets 315 on opposite sides. Both first mounting brackets 314 are bolted to the top of the machine tool 101.The automatic grinding assembly 1 includes a machine tool 101. A control system 5 is installed on the front surface of the machine tool 101. Two grinding systems 102 are installed on the top of the machine tool 101. Grinding wheels 103 are fixedly installed at the output ends of both grinding systems 102. A power system 104 is installed on the top of the machine tool 101 near one of the grinding systems 102. An intermittent rotary table 105 is fixedly installed at the output end of the power system 104, located between the two grinding wheels 103. A feeding system 107 is installed on the top of the machine tool 101 via an auxiliary plate, and a discharging system 106 is installed at the bottom of the intermittent rotary table 105. Two elastic silicone sheets 204 are located at the edges of the outer surfaces on both sides of the intermittent rotary table 105. A guide frame 316 is fitted onto the outer surface of the intermittent rotary table 105. Two mounting rods 323 are fixedly installed on the front and rear surfaces of the guide frame 316. One end of each of the four mounting rods 323 is fixedly installed inside the machine tool 101.

[0040] In this embodiment, during use, the feeding system 107 transports the metal accessory shaft to the material trough of the intermittent turntable 105. The intermittent turntable 105 is driven to rotate intermittently by the power system 104. When the accessory shaft passes under the vision monitoring component 2, the vision camera 202 acquires images and transmits the acquired images to the control system 5 for recognition and analysis via electrical signals. If the accessory shaft does not shift, it passes between the two elastic silicone sheets 204 without contacting them. In this case, the control system 5 determines that the accessory shaft is in a normal state and does not trigger the correction component 3. If the accessory shaft shifts, one end will be closer to one of the elastic silicone sheets 204 and the other end will be farther away from the other elastic silicone sheet 204. When the accessory shaft passes between the two elastic silicone sheets 204, the protruding end will contact the corresponding elastic silicone sheet 204 and force the elastic silicone sheet 204 to bend and deform. After the vision camera 202 transmits the captured image to the control system 5, the control system 5 determines that the accessory shaft posture is abnormal and that it has shifted based on the bent and deformed elastic silicone sheet 204, and then triggers the correction component 3. When the accessory shaft rotates and is conveyed to the bottom of the correction assembly 3, the forward and reverse motors 302 drive the fixed block 303 and the correction disc 304 to rotate, causing the two correction blocks 306 to rotate together. This forces the movable wheel 309 to roll in the correction groove 307 and move along the arc trajectory of the correction groove 307, thereby applying a thrust to the moving rod 308. Under the limitation of the support slip ring 311 and the support rod 312, the two moving rods 308 move relative to each other, thereby causing the two correction plates 317 to move relative to each other, pushing the offset accessory shaft to the center position, thus achieving the effect of correcting the posture. Then, the forward and reverse motors 302 drive the correction disc 304 to rotate in the opposite direction, causing the two moving rods 308 to move in the opposite direction through the correction blocks 306 and the correction groove 307, thereby causing the two correction plates 317 to move and reset, without affecting the subsequent correction of the accessory shaft. The corrected component shaft continues to be intermittently conveyed via the intermittent turntable 105, and then enters the guide frame 316. The width of the guide frame 316 matches the width of the component shaft, and the tail end of the guide frame 316 is close to the grinding wheel 103. This ensures that the corrected component shaft is guided by the guide frame 316 during subsequent conveying, preventing it from shifting again and keeping it centered when delivered to the grinding wheel 103 for grinding. Under the action of the vision monitoring component 2, the posture and position of the component shaft are monitored in real time. In conjunction with the control system 5, the intelligent triggering of the correction component 3 corrects the component shaft. Finally, guided by the path of the guide frame 316, the component shaft is kept in a centered position during grinding, avoiding uneven processing at both ends, which would lead to a decrease in grinding quality. This solves the problem that when the metal component shaft shifts position during feeding, the protective plate cannot adjust the component shaft, causing the component shaft to be ground in an abnormal posture, which easily leads to uneven processing at both ends, a sharp increase in parallelism error, a decrease in processing quality, and accelerated damage to the grinding tool.When the accessory shaft rotates between the two grinding wheels 103, the two grinding systems 102 drive the two grinding wheels 103 to rotate, and perform grinding on both ends of the accessory shaft. Then the processed accessory shaft falls onto the unloading system 106 for unloading and conveying, realizing automated double-end grinding.

[0041] Example 2: Figures 3-6 As shown, the visual monitoring component 2 includes a visual camera 202 and two reference marks 203. Elastic silicone sheets 204 are fixedly connected to the opposite sides of the two reference marks 203. The visual monitoring component 2 also includes a monitoring frame 201. Multiple first reference marks 205 are provided on the top of the two reference marks 203, and multiple second reference marks 206 are provided on the top of the two elastic silicone sheets 204. The first reference marks 205 and the second reference marks 206 are distributed in a straight line. The visual camera 202 is fixedly installed on the top surface inside the monitoring frame 201. The outer surfaces of the two reference marks 203 are respectively installed on the bottom surface of the opposite side inside the monitoring frame 201 by bolts.

[0042] In this embodiment, during use, the reference mark 203 and the elastic silicone sheet 204 form a judgment reference. The elastic silicone sheet 204 is flexible and deformable, while the reference mark 203 is fixed and serves as a reference positioning component, forming a "deformation comparison reference" in conjunction with the elastic silicone sheet 204. The vision camera 202 only needs to compare the parallelism between the elastic silicone sheet 204 and the reference mark 203 to determine whether the accessory shaft is offset. It only needs to identify the relative positional relationship between the elastic silicone sheet 204 and the reference mark 203, which is far less difficult than workpiece contour recognition, simplifying the visual recognition logic.

[0043] Furthermore, a first reference mark 205 and a second reference mark 206 are respectively set on the top of the reference mark 203 and the elastic silicone sheet 204. The first reference mark 205 and the second reference mark 206 are different colors, and the first reference mark 205 and the second reference mark 206 form a straight line. When the elastic silicone sheet 204 bends and deforms, it will cause the position of the second reference mark 206 to change. By collecting the changes in the second reference mark 206, the offset of the accessory shaft can also be determined. The intensity of light in the work area will affect the recognition of the outline of the elastic silicone sheet 204, but the color saturation of the color marks is less affected by the light. For example, the first reference mark 205 and the second reference mark 206 are red and blue respectively, and the red and blue marks can still maintain obvious color differences under strong or weak light, avoiding monitoring failure caused by changes in light and improving the accuracy of visual monitoring results.

[0044] Example 3: Figures 8-14As shown, the automatic grinding assembly 1 is equipped with a vision monitoring assembly 2 and a correction assembly 3 on its top. The correction assembly 3 contains a connecting assembly 4. The correction assembly 3 includes a correction frame 301. A forward / reverse motor 302 is fixedly mounted on the top surface inside the correction frame 301. A fixing block 303 is fixedly mounted on the output end of the forward / reverse motor 302. A correction disc 304 is fixedly mounted on the bottom of the fixing block 303. Two mounting slots 305 are formed on the top surface of the correction disc 304. A correction block 306 is movably embedded inside each of the two mounting slots 305. Movable wheels 309 are movably fitted onto the top ends of two moving rods 308. The outer surfaces of the two moving wheels 309 are movably embedded inside the two correction slots 307. Each component has a threaded limit screw 310. Two support slip rings 311 are fixedly installed on the outer surfaces of the two moving rods 308. The connecting component 4 includes an H-shaped clamping plate 401. An inner concave toothed ring 402 is fixedly installed inside the H-shaped clamping plate 401. A connecting rod 404 is movably embedded inside the inner concave toothed ring 402. A convex rod disc 403 is fixedly installed at the bottom end of the connecting rod 404. An annular plate 406 is fixedly installed on the outer surface of the connecting rod 404. A limit ring 407 and a return spring 408 are movably sleeved on the outer surface of the connecting rod 404. Two insert rods 409 are fixedly installed at the bottom edge of the annular plate 406. Two slots 410 are opened at the top of the H-shaped clamping plate 401. A rotating block 405 is fixedly installed at the top end of the connecting rod 404. The outer surface of the convex rod plate 403 is movably embedded in the lower groove 320. The top end of the connecting rod 404 movably passes through the H-shaped clamping plate 401, the inner groove 319, and the movable groove 321 to the top of the correction plate 304. The outer surface of the limiting ring 407 is movably embedded in the annular plate 406. One end of the return spring 408 is fixedly connected to the bottom of the limiting ring 407. The other end of the return spring 408 is fixedly connected to the bottom surface inside the movable groove 321. The outer surface of the annular plate 406 is movably embedded in the movable groove 321. The outer surfaces of the two insert rods 409 are movably embedded in the two arc-shaped grooves 322, and the bottom ends of the two insert rods 409 are movably embedded in the two slots 410. Four connecting components 4 are provided. One end of each of the four H-shaped clamping plates 401 is movably embedded in the four clamping slots 318, and the outer surfaces of the four H-shaped clamping plates 401 are movably embedded in the four inner grooves 319.

[0045] In this embodiment, during use, the correction component 3 is bolted to the automatic grinding component 1 for easy disassembly and installation. Pulling the rotating block 405 upward causes the connecting rod 404 to move upward, simultaneously causing the convex rod disc 403 and the annular plate 406 to move upward, so that the convex rod disc 403 enters the interior of the concave toothed ring 402 and engages with it. The annular plate 406 drives the insertion rod 409 to move from the slot 410 to the arc-shaped groove 322, and by pulling the limiting ring 407, the return spring 408 unfolds. When the annular plate 406 contacts the movable groove 321, the rotating block 405 can no longer be pulled. Then, the rotating block 405 is rotated, causing the annular plate 406 to rotate, which in turn causes the two insertion rods 409 to rotate in the corresponding arc-shaped grooves 322. At the same time, the convex rod disc 403 drives the concave toothed ring 402 to rotate, and then drives the H-shaped clamping plate 401 to rotate, so that one end of it that is inserted into the clamping slot 318 rotates out into the inner groove 319. After the H-shaped card plate 401 rotates 90 degrees, the insertion rod 409 abuts against the inner wall of the arc-shaped groove 322 and cannot continue to rotate. Then, the rotating block 405 is released, and the return spring 408 pulls the limiting ring 407, the annular plate 406, and the connecting rod 404 downwards, so that the insertion rod 409 is inserted into the slot 410 again, and the convex rod plate 403 is removed from the concave toothed ring 402. The connecting assembly 4 is provided with four. Repeat the above operation to rotate multiple H-shaped card plates 401 into the corresponding embedded grooves 319 in sequence. At this time, the correction block 306 loses its connection with the mounting groove 305. Then, rotate the limiting screw 310 to unscrew it from the top of the moving rod 308. Finally, lift the correction block 306 from the mounting groove 305, causing the movable wheel 309 to leave the top of the moving rod 308. Then, the correction block 306 with different specifications of correction groove 307 can be replaced. Figure 14 As shown, this facilitates the adjustment of accessory shafts of different widths.

[0046] The overall mechanism works as follows: the feeding system 107 transports the metal part shaft to the trough of the intermittent turntable 105; the power system 104 drives the intermittent turntable 105 to rotate intermittently; the vision camera 202 acquires images and transmits the acquired images to the control system 5 for recognition and analysis via electrical signals. If the part shaft does not deviate, it passes between the two elastic silicone sheets 204 without contacting them. In this case, the control system 5 determines that the part shaft is in a normal state and does not trigger the correction component 3. If the part shaft deviates and passes between the two elastic silicone sheets 204, the protruding end will force the elastic silicone sheets 204 to bend and deform. The control system 5 determines that the part shaft's posture is abnormal and that it has deviated, and then triggers the correction component 3. The forward and reverse motors 302 drive the fixed block 303 and the correction disc 304 to rotate, causing the two correction blocks 306 to rotate together. This forces the movable wheel 309 to move along the arc-shaped trajectory of the correction groove 307, thereby applying a thrust to the moving rod 308. Under the limitation of the support slip ring 311 and the support rod 312, the two moving rods 308 move relative to each other, thereby causing the two correction plates 317 to move relative to each other, pushing the offset accessory shaft to the center position. Then, the forward and reverse motors 302 drive the two correction plates 317 to move and reset. The corrected accessory shaft continues to be intermittently conveyed through the intermittent turntable 105, and then enters the guide frame 316, keeping the corrected accessory shaft in the center position and sending it to the grinding wheel 103. The two grinding systems 102 drive the two grinding wheels 103 to rotate, grinding both ends of the accessory shaft. Then, the processed accessory shaft falls onto the unloading system 106 for unloading and conveying, realizing automated double-end surface grinding processing. The first reference mark 205 and the second reference mark 206 form a straight line. When the elastic silicone sheet 204 bends and deforms, it will cause the position of the second reference mark 206 to change. By collecting the changes in the second reference mark 206, the offset of the accessory shaft can also be determined. The color saturation of the color marks is less affected by light. The red and blue marks can still maintain obvious color differences under strong or weak light, avoiding monitoring failure caused by changes in light. Pulling the rotating block 405 upward causes the connecting rod 404, the convex rod disc 403, and the annular plate 406 to move upward, so that the convex rod disc 403 engages inside the concave toothed ring 402. The annular plate 406 moves the insert rod 409 from the slot 410 to the arc-shaped groove 322, and the return spring 408 is unfolded by pulling the limiting ring 407. When the annular plate 406 contacts the movable groove 321, rotating the rotating block 405 causes the annular plate 406 to rotate, which in turn causes the two insert rods 409 to rotate in the arc-shaped groove 322. At the same time, the convex rod disc 403 drives the concave toothed ring 402 to rotate, which then drives the H-shaped clamping plate 401 to rotate and rotate out of the clamping groove 318.Next, release the rotating block 405. The return spring 408 pulls the limiting ring 407, the annular plate 406, and the connecting rod 404 downwards, causing the insertion rod 409 to re-insert into the slot 410, and the convex rod disc 403 to move out of the concave toothed ring 402. Repeat the above operation to rotate multiple H-shaped clamping plates 401 out of the clamping slot 318. Then, rotate the limiting screw 310 to move it away from the top of the moving rod 308. Finally, lift the correction block 306 out of the mounting slot 305. This allows you to replace the correction block 306 with different specifications of correction slot 307, facilitating the correction of accessory shafts of different widths.
