Description

Technical Field

[0001] This invention relates to the field of hardware polishing technology, and in particular to an automated hardware polishing equipment. Background Technology

[0002] Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting. They are used to fix things, process things, and decorate. When polishing hardware, external polishing equipment is required.

[0003] Traditional hardware polishing processes generally suffer from the following technical bottlenecks:

[0004] 1. For irregularly shaped parts with protruding cylindrical structures, conventional fixtures are difficult to integrate stable clamping and synchronous polishing. They often require additional clamping devices for secondary clamping and polishing, resulting in low processing efficiency and errors in positioning during re-clamping, which also increases equipment costs.

[0005] 2. Existing polishing equipment lacks adaptability to complex curved surfaces, especially when dealing with the transition area between edges and curved surfaces, which is prone to over-polishing or under-polishing defects caused by uneven polishing pressure.

[0006] 3. Existing robotic arms and polishing mechanisms lack a real-time feedback mechanism when working together, making it difficult to ensure the consistency of polishing complex surfaces. These problems severely restrict the automation upgrade of the hardware polishing process, necessitating the development of an intelligent processing device that integrates adaptive clamping, multi-face synchronous polishing, and process monitoring. We propose an automated hardware polishing processing device. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0021] 1.

[0022] 2. This invention, by setting up a drive module and an auxiliary module, can achieve adaptive polishing of hardware parts. Specifically, the double roller elastic tensioning mechanism, with the first roller and the second roller working in conjunction with the second and third springs, allows the polishing belt to dynamically conform to the contour of the workpiece. The vertical floating of the first roller and the horizontal displacement of the second roller form a compound compensation, ensuring that the edges and curved surfaces can maintain a constant polishing pressure. In addition, the movable block, through the rotational freedom pre-tightened by the torsion spring, actively presses the polishing belt under the push of the second electric push rod, further ensuring the fit between the polishing belt and the hardware parts, and ensuring the polishing effect of the hardware parts.

[0023] 3. By setting up a first detection block and a second detection block and their surrounding components, the present invention can effectively monitor the polishing process. Specifically, the first detection block can detect the displacement of the first roller by detecting the deformation of the support cylinder, and compare it with the movement trajectory of the robotic arm in real time to automatically identify whether the corresponding polishing surface is effectively polished. In addition, the second detection block can monitor the traction force of the mating rod in real time during the clamping mode, ensuring that the pressure of the polishing belt adhering to the hardware is not too high, while also ensuring the stability of the subsequent workpiece clamping.

[0024] 4. By setting a mating plate and a movable block and their surrounding components, the present invention can realize a multi-functional setting for grinding and clamping. Specifically, by switching the state of the mating plate and the movable block, i.e. locking or releasing the clamping rod, the grinding real-time detection and clamping of hardware parts can be completed in the same workstation.

[0025] 5. By setting up an auxiliary module and a clamping mechanism, after the auxiliary module clamps the hardware, the clamping block can be slightly loosened by the electric gripper, and the polishing block can be attached to the side of the protruding cylinder of the hardware. The robotic arm turntable rotates the electric gripper, and the polishing block can be used to polish the protruding cylinder of the hardware, realizing the complete polishing operation of the hardware in a single station.

[0037] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0038] Example: Figure 1 As shown, an automated polishing equipment for hardware parts includes a robotic arm 1, which is a standard mechanical and electrically controlled arm with a turntable. A clamping mechanism 2 is provided on the side of the turntable of the robotic arm 1. A control cabinet 11 is provided on the side of the robotic arm 1. The control cabinet 11 is a rectangular cabinet with control, power supply and monitoring modules inside. An electric slide table 12 is vertically provided on the side of the control cabinet 11. A polishing mechanism 3 is provided on the side of the slide table 12.

[0039] The clamping mechanism 2 can clamp the hardware with protruding cylinders, and work with the robotic arm 1 to perform omnidirectional movement and polishing. The protruding cylinders of the hardware can be polished directly afterward.

[0040] like Figures 1 to 2As shown, the clamping mechanism 2 includes an electric gripper 21 fixedly installed on the side of the turntable of the robotic arm 1. The electric gripper 21 is an electrically controlled gripper. A clamping block 22 is fixedly installed on the side of the electric gripper 21 in a mirror image. The clamping block 22 is an arc-shaped block. A movable groove 23 is mirror-shaped on the side of the clamping block 22. The movable groove 23 is a rectangular groove with a convex cross-section. A polishing block 24 is movably installed inside the movable groove 23, and part of the polishing block 24 extends out of the interior of the movable groove 23. The polishing block 24 is a rectangular block of polishing material with a convex cross-section. There is an equidistant fixed distance between the side of the polishing block 24 and the wall of the movable groove 23. A first spring 25 is fixedly connected; specifically, when clamping the hardware, the electric gripper 21 drives the clamping block 22 to move closer to clamp the protruding cylinder of the hardware, and the polishing block 24 is squeezed and completely slides into the position inside the movable groove 23; during polishing, after the subsequent hardware is clamped, the electric gripper 21 controls the clamping block 22 to move slightly away, and the elastic force of the first spring 25 supports the polishing block 24 to slide out of the movable groove 23 and fit against the side of the protruding cylinder of the hardware. The turntable of the robotic arm 1 drives the electric gripper 21 to rotate, so that the polishing block 24 can be used to polish the protruding cylinder of the hardware.

[0041] The polishing mechanism 3 can be adapted to the surface of different hardware parts for polishing operations, and can switch to clamp and fix hardware parts in conjunction with the clamping mechanism 2 to perform raised cylindrical polishing operations.

[0042] like Figures 3 to 5 As shown, the polishing mechanism 3 includes a mounting frame 31 fixedly installed on the side of the electric slide table 12. The mounting frame 31 is a "C"-shaped frame. A mounting cavity 32 is provided through the side of the mounting frame 31. The mounting cavity 32 is a "C"-shaped cavity. Inside the mounting cavity 32, a drive module 4 that can fit and conform to the side of the hardware and an auxiliary module 5 that can detect and clamp the hardware in real time are respectively provided.

[0043] The overall elastic setting can be achieved through the set drive module 4, and the polishing belt 43 can be elastically fitted to the side of the hardware during polishing.

[0044] like Figures 3 to 7As shown, the drive module 4 includes first rollers 41 symmetrically arranged inside the mounting cavity 32, with the first rollers 41 corresponding to the recessed positions of the mounting bracket 31. The first rollers 41 are I-shaped rollers with round shafts on both sides. First grooves 411, which penetrate the mounting bracket 31, are vertically formed on both side walls of the mounting cavity 32 corresponding to the positions of the first rollers 41. The first grooves 411 are rectangular grooves. A first slider 412 is movably mounted inside the first groove 411, and the round shafts on both sides of the first rollers 41 are rotatably mounted on the sides of the first slider 412. The first rollers 41 can rotate under the constraint and support of the first slider 412. A first... A first constraint rod 413 passes through a first slider 412. The first constraint rod 413 is a cylindrical rod. A second spring 414 is movably sleeved on the side of the first constraint rod 413. A second roller 42 is provided inside the mounting cavity 32. The second roller 42 is an I-shaped roller with round shafts on both sides. A second groove 421 is horizontally opened on both side walls of the mounting cavity 32 corresponding to the position of the second roller 42, passing through the mounting bracket 31. The second groove 421 is a rectangular groove. A second slider 422 is movably installed inside the second groove 421, and the round shafts on both sides of the second roller 42 pass through and rotate on the side of the second slider 422. The second roller 42 can be supported by the second slider. The constraint support 422 rotates. A second constraint rod 423 is symmetrically fixedly installed on the wall of the second slide groove 421 and passes through the second slider 422. The second constraint rod 423 avoids the position of the circular shaft on the side of the second roller 42. A third spring 424 is fixedly connected between the side of the second slider 422 and the wall of the second slide groove 421. A mating frame 425 is fixedly installed on the side of the second slider 422 and slides inside the second slide groove 421. The mating frame 425 is a "T"-shaped bent sheet metal frame with a circular hole on the side. The mating frame 425 is movably sleeved on the side of the second constraint rod 423. A micro motor 426 is fixedly mounted on the side, and the output end of the micro motor 426 passes through the mating frame 425 and is fixedly connected to the circular shaft position on the side of the second roller 42. A polishing belt 43 is movably sleeved on the side of the second roller 42 and the first roller 41. Specifically, by default, the first slider 412 and the second slider 422 can be elastically supported by the second spring 414 and the third spring 424, so that the first roller 41 and the second roller 42 cooperate to provide elastic support for the polishing belt 43. When the micro motor 426 drives the second roller 42 to rotate, it can drive the polishing belt 43 to rotate cyclically on the side of the first roller 41 and the second roller 42, so that the polishing belt 43 can perform polishing operation on the hardware.During polishing, after the hardware parts are attached to the side of the polishing belt 43, the polishing belt 43 is squeezed and attached to its curved and corner surfaces for fitting polishing. Simultaneously, the first slider 412 is constrained by the first constraint rod 413 and squeezes the second spring 414 to deform, driving the two sets of first rollers 41 to move closer together. At the same time, the second slider 422 is elastically supported by the third spring 424 and is constrained by the second constraint rod 423 to slide, driving the second roller 42 to move away from the first roller 41, so that the polishing belt 43 can always be elastically supported by the first roller 41 and the second roller 42. When the second roller 42 moves, the second slider 422 synchronously drives the mating frame 425 to slide inside the second slide groove 421 under the constraint of the second constraint rod 423, which drives the micro motor 426 to move accordingly, so that the micro motor 426 can continuously drive the second roller 42.

[0045] The auxiliary module 5 can detect the elastic support force of the first roller 41 and the second roller 42 in real time, and can improve the fit between the polishing belt 43 and the side of the hardware during polishing. In addition, it can trigger the clamping operation of the hardware in the future.

[0046] like Figures 3 to 5 and Figures 7 to 10As shown, the auxiliary module 5 includes a connecting frame 51 fixedly installed on the side of the first slider 412 and slidably installed inside the first slide groove 411. The connecting frame 51 is movably sleeved on the side of the first constraint rod 413, and the first constraint rod 413 fits against the side of the connecting frame 51. The connecting frame 51 is a continuously bent sheet metal part. A connecting rod 52 is fixedly installed at the center of the side of the connecting frame 51 away from the first roller 41. The connecting rod 52 is a cylindrical rod. A movable cavity 521 is opened on the side of the connecting rod 52 away from the connecting frame 51. The movable cavity 521 is a cylindrical cavity with a convex cross-section. A mating rod 522 is movably installed inside the movable cavity 521. The mating rod 522 extends out of the interior of the movable cavity 521. The mating rod 522 is a T-shaped round rod. A first detection block 523 and a second detection block 524 are fixedly installed on the side of the mating rod 522. The first detection block 523 and the second detection block 524 can be ring-shaped pressure sensors capable of detecting minute pressures. By default, the second detection block 524 is attached to the wall of the movable cavity 521. A support cylinder 525 is fixedly connected between the side of the first detection block 523 and the wall of the movable cavity 521. The support cylinder 525 is a corrugated cylinder made of elastic material. A mating plate 53 is fixedly installed on the side of the mating rod 522 away from the connecting frame 51. 3. The mating plate 53 is a rectangular plate that fits against the wall of the mounting cavity 32. A slot 55, which is rectangular, is equidistantly provided on the wall of the mounting cavity 32 corresponding to the position of the mating plate 53. An inner cavity 532, which is T-shaped, is provided on the side of the mating plate 53 corresponding to the position of the slot 55. A locking rod 533 is movably installed inside the inner cavity 532, with a portion of the locking rod 533 extending out of the inner cavity 532 and engaging with the position inside the slot 55. The locking rod 533 is T-shaped. Specifically, when the first roller 41 moves closer together, the connecting frame 51 moves synchronously with the first roller 41, at which time the locking rod 533 inserts into the slot 55. The position of the mating plate 53 restricts the support of the mating rod 522. The mating rod 522 slides and compresses the support cylinder 525 inside the movable cavity 521, causing it to deform. When the support cylinder 525 deforms, it compresses the first detection block 523. The first detection block 523 feeds back the pressure to the external controller, which can determine the position variable of the first roller 41 in real time. This allows the robot arm 1 program to compare the polishing process and determine whether the side of the polished hardware can be aligned. (That is, when polishing different surfaces of the hardware, different compression variables are produced on the polishing belt 43, causing the first roller 41 to move closer to the corresponding position.) This allows for real-time monitoring of the polishing process.

[0047] The mating plate 53 has a through slot 531 on its side, which passes through the interior of the cavity 532. The locking rod 533 has a through connecting slot 534 on its side. The movable block 543 is a U-shaped slot. A first electric actuator 535 is fixedly connected to the side of the locking rod 533 and is fixedly installed inside the mating plate 53. A second electric actuator 54 is provided inside the mounting cavity 32 corresponding to the position of the mating plate 53, and is fixedly installed on the wall of the mounting cavity 32 by a bracket. A mating block 541 is fixedly installed at the output end of the second electric actuator 54 and is located in the slot 532. Inside the connecting groove 534, the mating block 541 is an I-shaped cylindrical block. A notch 542, rectangular in shape, is formed on the side of the mating block 541 away from the second electric actuator 54. A movable block 543, T-shaped, is movably disposed inside the notch 542. A movable rod 544, also I-shaped, is fixedly mounted on the side of the movable block 543, extending through the second electric actuator 54 at both ends. A torsion spring 545, mirror-fixed on the inner side of the movable rod 544, is also fixedly mounted on the side of the mating block 541. Specifically... By default, the locking rod 533 is engaged inside the slot 55, with the inner protrusion of the locking rod 533 positioned inside the locking rod 533. At this time, the mating plate 53 supports the mating rod 522. When the hardware is attached to the side of the polishing belt 43, the second electric push rod 54 can push the mating block 541 to move, and the movable block 543 is attached to the inner side of the polishing belt 43. Rotating with the movable rod 544 as the rotation center, the polishing belt 43 can better fit against the sides of the hardware for polishing operations. During clamping, the first electric push rod 535 can pull the locking rod 533 to slide inside the inner cavity 532. At this time, the inner protrusion of the locking rod 533 is recessed on the side of the mating block 541. When the device is positioned in the recessed position and disengaged from the slot 55 into the mating plate 53, and the second electric push rod 54 pushes the mating block 541 to move, the mating plate 53 can move synchronously with the mating plate 53. At this time, the mating rod 522 is pulled along with the mating plate 53, and the second detection block 524 adheres to the wall of the movable cavity 521 to generate pressure feedback to the external controller. The connecting rod 52 then moves with the mating rod 522 to pull the connecting frame 51, causing the first roller 41 to move closer together. The movable block 543 can then clamp the side of the hardware. The mating plate 53 can also cooperate to clamp the hardware. The polishing belt 43 adhering to the side of the hardware can also increase the friction.

[0048] Working principle:

[0049] Before use: The mechanical arm 1 moves the clamping mechanism 2, and the electric gripper 21 controls the clamping block 22 to clamp the protruding cylinder of the hardware. At the same time, the polishing block 24 slides completely into the position inside the movable groove 23. In this way, the mechanical arm 1 can drive the clamped hardware to rotate in all directions and cooperate with the polishing mechanism 3 to perform polishing operations. The electric slide table 12 drives the mounting bracket 31 to move in position to adapt to polishing.

[0050] In use: First step, polishing adaptation: The hardware held by the clamping mechanism 2 is pressed against the side of the polishing belt 43 for polishing. Simultaneously, the polishing belt 43 is squeezed and moves closer to the recess of the mounting bracket 31. At this time, the two sets of first rollers 41 move closer together. The first slider 412 slides inside the first groove 411 and squeezes the second spring 414 to deform. At the same time, the second slider 422 slides under the elastic support of the third spring 424, so that the second roller 42 moves accordingly. Together with the first roller 41, it maintains a continuous support effect on the polishing belt 43. The micro motor 426 drives the second roller 42. The rotating motion allows the polishing belt 43 to perform cyclical polishing operations. When the first roller 41 moves closer together, the connecting frame 51 can synchronously drive the connecting rod 52 to move. The mating plate 53 is fixed in a limited position, and the mating rod 522 can slide and squeeze the support cylinder 525 to deform inside the movable cavity 521. The pressure signal received by the first detection block 523 is fed back to the external controller, which can determine the position of the first roller 41 approaching each other. With the comparison of the mechanical arm 1 driver program, it can detect in real time whether the deformation amount of the polishing belt 43 is appropriate when polishing different surfaces of the hardware.

[0051] The second step is to enhance polishing: When polishing non-arc surfaces, the mating plate 53 is fixed by the clamping rod 533, and the second electric push rod 54 pushes the mating block 541 closer to the hardware. The movable block 543 rotates around the movable rod 544 as the rotation center and fits against the inner side of the polishing belt 43, so that the polishing belt 43 can fit more closely to the side of the hardware for polishing, ensuring the polishing effect of the side of the hardware.

[0052] The third step, final polishing: The mechanical arm 1 drives the clamping mechanism 2 to adjust the position of the hardware held in the recess of the mounting bracket 31. Simultaneously, at this time, the first electric push rod 535 pulls the locking rod 533 out of the slot 55. The inner protrusion of the locking rod 533 slides into the recess of the mating block 541. The locking rod 533 can limit and constrain the mating block 541. The second electric push rod 54 pushes the mating block 541 closer to the hardware. The mating plate 53 can simultaneously drive the mating rod 522 to move. At this time, the first roller 41 is pulled by the mating rod 522 to actively bring the connecting rod 52 and the connecting bracket 51 closer together. The second detection block 524 receives force feedback and sends it to the external controller, which determines that the first roller 41 has actively approached the target. The hardware part can be clamped by the movable block 543 and the mating plate 53. The polishing belt 43 is attached between the movable block 543, the mating plate 53 and the hardware part to increase the clamping friction. Then, the electric gripper 21 slightly loosens the gripper 22, so that the polishing block 24 slides out of the movable groove 23 and attaches to the side of the protruding cylinder of the hardware part. The turntable of the robotic arm 1 rotates the electric gripper 21, so that the polishing block 24 can polish the protruding cylinder of the hardware part. In this way, the hardware part can be completely polished in a single station.

[0053] After use: The polished hardware parts held by the robotic arm 1 and the clamping mechanism 2 are placed in the product placement area. The internal components of the polishing mechanism 3 are reset. When the first roller 41 is reset, the pressure signal fed back by the first detection block 523 determines whether the first roller 41 has been reset. If it has not been reset, the first electric push rod 535 pulls the locking rod 533 out of the slot 55 and slides into the inner cavity 532. The second electric push rod 54 can then drive the mating plate 53 to the position of the corresponding slot 55 through the push-pull mating block 541. Then the first electric push rod 535 pushes the locking rod 533 to engage in the corresponding slot 55. The position adjustment of the mating rod 522 allows the first roller 41 to be fully reset.
