Abstract
Description
Technical Field
[0001] This invention relates to the field of wire mesh grinding technology, specifically to an automatic edge grinding device for fence mesh. Background Technology
[0002] As an important safety protection facility, fence panels are widely used in highways, railways, airports, factories, and municipal engineering projects. The fence panels are typically formed by welding steel wire. After welding, defects such as burrs, weld slag, and oxide scale inevitably occur at the edges and weld points. These defects not only affect the appearance quality of the mesh but also easily lead to reduced coating adhesion in subsequent surface treatment processes such as dip coating and powder coating. Furthermore, they may pose a risk of scratches to construction workers during actual installation.
[0003] Currently, the industry primarily relies on manual handheld angle grinders or simple fixed grinding equipment for semi-automatic processing to treat the edges of fence panels. However, manual grinding is labor-intensive, inefficient, and the grinding quality is greatly affected by the operator's skill level, making it difficult to guarantee consistency. Furthermore, the metal dust and splatter generated during grinding pose significant health hazards to operators. While existing automatic grinding equipment can improve efficiency to some extent, it generally suffers from the following shortcomings: First, it lacks automatic detection and adaptive positioning functions for the edge positions of the mesh panels, making it difficult to adapt to the processing needs of mesh panels of different specifications; second, the grinding mechanism is mostly set in a single direction, making it difficult to simultaneously achieve all-round grinding of the mesh surface and sides, resulting in poor treatment of the beveled sides of the mesh panels.

[0018] 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.
[0019] like Figure 1-2 As shown, this embodiment of the invention provides an automatic edge grinding device for fence mesh, including a main body 1, a placement mechanism 2 fixedly disposed on the surface of the main body 1, an edge detection mechanism 3 slidably disposed on one side of the placement mechanism 2, and a surface grinding mechanism 4 and a side grinding mechanism 5 slidably disposed on the other side of the placement mechanism 2.
[0020] Specifically, the main body 1 serves as the mounting base and support frame for the entire device, providing a stable mounting platform for the placement mechanism 2, edge detection mechanism 3, surface grinding mechanism 4, and side grinding mechanism 5. The placement mechanism 2 is fixedly positioned in the middle of the main body 1, used to support and fix the fence mesh to be ground, and can rotate in the horizontal plane to adjust the grinding orientation of the mesh. The edge detection mechanism 3 is slidably connected to the main body 1 via a slide rail, and can reciprocate horizontally to perform real-time detection and positioning of the mesh's edge contour. Both the surface grinding mechanism 4 and the side grinding mechanism 5 are slidably connected to the main body 1 via slide rails, and are arranged side-by-side on the opposite side of the placement mechanism 2 relative to the edge detection mechanism 3, respectively used for grinding the upper surface and side edges of the mesh. All mechanisms are arranged in a linear array along the slide rails on the surface of the main body 1, and the movement directions of the edge detection mechanism 3, surface grinding mechanism 4, and side grinding mechanism 5 all point towards the center area of the placement mechanism 2, thus facilitating adaptive detection and grinding of meshes of different sizes.
[0021] like Figure 3-4 As shown, the main body mechanism 1 includes a base plate 103, a main frame 101 fixedly mounted at the rear end of the base plate 103, multiple slide rails 102 fixedly mounted on the surface of the base plate 103, a vacuum cleaner 104 fixedly mounted on the surface of the base plate 103, a vacuum cleaner head 105 fixedly mounted at the vacuum cleaner end of the vacuum cleaner 104, a hydraulic cylinder 106 fixedly mounted at the bottom end of the main frame 101, multiple bearings 107 fixedly mounted inside the hydraulic cylinder 106, a rotating shaft 108 rotatably mounted on the hydraulic cylinder 106 via the bearings 107, an upper pressure plate 109 fixedly mounted at the bottom end of the rotating shaft 108, multiple first guide rods 110 fixedly mounted inside the upper pressure plate 109, positioning pins 112 slidably mounted on the surface of each of the multiple first guide rods 110, and a first spring 111 fixedly mounted between the multiple positioning pins 112 and the upper pressure plate 109.
[0022] Specifically, the base plate 103 is a rectangular metal plate, fixed to the workshop floor with anchor bolts to ensure the overall structural stability of the device. The main frame 101 is a gantry frame structure, vertically fixed at the rear edge of the base plate 103, with its top crossbeam extending horizontally forward to provide suspended support for the hydraulic cylinder 106. Multiple slide rails 102 are provided, parallel to each other and arranged along the front-rear direction of the base plate 103. The guide surfaces of the slide rails 102 are parallel to the surface of the base plate 103, providing precise linear guidance for the edge detection mechanism 3, the surface grinding mechanism 4, and the side grinding mechanism 5. The vacuum cleaner 104 is fixedly mounted on one side of the base plate 103 surface via a bracket. Its suction port is connected to the suction head 105 via a flexible hose. The suction nozzle of the suction head 105 faces the grinding operation area where the mechanism 2 is placed, used to extract metal dust and debris in real time during the grinding process. The cylinder body of hydraulic cylinder 106 is vertically fixed to the middle position of the top crossbeam of the main frame 101 via a flange, and the piston rod of hydraulic cylinder 106 is arranged vertically downwards. Two bearings 107 are provided, and the two bearings 107 are embedded in the lower end of the piston rod of hydraulic cylinder 106 at intervals along the vertical direction, forming a rotation support structure together. The rotating shaft 108 is a stepped shaft, and its upper end is rotatably connected to the piston rod of hydraulic cylinder 106 via bearings 107. The axis of rotating shaft 108 coincides with the axis of piston rod of hydraulic cylinder 106, so that rotating shaft 108 can rotate freely relative to hydraulic cylinder 106 around its own axis. The upper pressure plate 109 is a circular plate structure with a diameter smaller than the width of common guardrail mesh. The center position of the upper surface of the upper pressure plate 109 is fixedly connected to the bottom end of rotating shaft 108 by bolts, so that upper pressure plate 109 can rise, fall and rotate synchronously with rotating shaft 108.
[0023] Multiple first guide rods 110 are provided, evenly distributed along the circumference of the upper pressure plate 109, and vertically fixedly embedded in the guide holes opened on the upper pressure plate 109. The positioning pins 112 are cylindrical structures, their outer diameter matching the diameter of the positioning holes 202 on the placement plate 201. Each positioning pin 112 has a sliding hole at its center along the axial direction that matches the first guide rod 110. The positioning pin 112 slides along the outer surface of the first guide rod 110 through this sliding hole, allowing it to slide up and down along the first guide rod 110. A first spring 111 is sleeved on the outer circumference of the first guide rod 110. The upper end of the first spring 111 is fixedly connected to the bottom surface of the upper pressure plate 109, and the lower end of the first spring 111 is fixedly connected to the top surface of the positioning pins 112. In its natural state, the first spring 111 is in the open state, pushing the positioning pin 112 downwards, causing the lower end of the positioning pin 112 to protrude from the bottom surface of the upper pressure plate 109. When the hydraulic cylinder 106 drives the upper pressure plate 109 to press the mesh downwards, if the lower end of the positioning pin 112 is aligned with the positioning hole 202 on the placement plate 201, the positioning pin 112 is inserted into the positioning hole 202 under the elastic thrust of the first spring 111, achieving precise circumferential positioning between the upper pressure plate 109 and the placement plate 201, preventing the mesh from shifting circumferentially during the rotation and grinding process; if the lower end of the positioning pin 112 is not aligned with the positioning hole 202 and is blocked by the solid part of the wire mesh, the positioning pin 112 is subjected to the upward reaction force of the mesh, slides upwards along the first guide rod 110 and compresses the first spring 111, causing the positioning pin 112 to elastically retract into the guide hole of the upper pressure plate 109, avoiding the positioning pin 112 from forcibly piercing the mesh and causing damage to the mesh. Thus, by cooperating with the positioning pin 112 and the positioning hole 202, adaptive elastic positioning of the mesh is achieved, which not only ensures positioning accuracy but also avoids damage to the mesh caused by rigid pressing.
[0024] like Figure 5-6 As shown, the placement mechanism 2 includes a control box 207. A drive motor 210 is fixedly installed inside the control box 207. A lower support 204 is fixedly installed on the upper surface of the control box 207. Sliding grooves 205 are opened around the surface of the lower support 204. A through hole 206 is opened in the middle of the surface of the lower support 204. A door 208 is hinged to the front of the control box 207. A controller 209 is fixedly installed on the surface of the door 208. The output end of the drive motor 210 is fixedly connected to the placement plate 201 through the through hole 206. Multiple positioning holes 202 are opened on the upper surface of the placement plate 201. Multiple balls 203 are slidably arranged on the bottom surface of the placement plate 201. The positions of the multiple balls 203 correspond to the sliding grooves 205.
[0025] Specifically, the control box 207 is a closed rectangular box, bolted to the center of the base plate 103. The internal cavity of the control box 207 houses the electrical control components and the drive motor 210. The drive motor 210 is fixed to the bottom of the control box 207's inner cavity via a motor bracket. The output shaft of the drive motor 210 is connected to a reducer, with the output end vertically upwards, and the axis of the output shaft coincides with the axis of the piston rod of the hydraulic cylinder 106. The lower support 204 is a disc-shaped structure, its outer diameter also smaller than the minimum width of common guardrail mesh panels. The lower surface of the lower support 204 is bolted to the upper surface of the control box 207. The slide groove 205 is an annular groove, continuously formed circumferentially along the upper surface of the lower support 204. The cross-section of the slide groove 205 is semi-circular, used to accommodate and guide the balls 203 to reduce friction between them during rotation. A through hole 206 is located at the center of the lower support 204. The diameter of the through hole 206 is larger than the diameter of the output shaft of the drive motor 210, providing space for the drive motor 210 output shaft to pass through. One side of the door 208 is hinged to the front opening edge of the control box 207. The door 208 can be opened outward around the hinge, facilitating the operator to inspect and maintain the electrical components and drive motor 210 inside the control box 207. The controller 209 is fixedly embedded in the outer surface of the door 208. The controller 209 is an industrial control unit integrating a microprocessor, memory, and communication interface. The controller 209 is electrically connected to the drive motor 210, the solenoid valve of the hydraulic cylinder 106, the vacuum cleaner 104, and the edge detection mechanism 3, surface grinding mechanism 4, and side grinding mechanism 5 via cables. It is used to receive detection signals from each sensor and output control commands to coordinate the cooperative actions of each mechanism.
[0026] The placement plate 201 is a disc-shaped metal plate with a diameter that matches the outer diameter of the lower support 204. The center of the lower surface of the placement plate 201 is fixedly connected to the output shaft of the drive motor 210 via a coupling, allowing the placement plate 201 to rotate horizontally around its own axis under the drive of the drive motor 210. Multiple positioning holes 202 are provided, evenly distributed along the circumference of the placement plate 201. The positioning holes 202 are circular blind holes, and their distribution positions correspond one-to-one with the distribution positions of multiple positioning pins 112 on the upper pressure plate 109, enabling the positioning pins 112 to be accurately inserted into the positioning holes 202 to achieve circumferential positioning of the mesh. Multiple balls 203 are provided, evenly embedded along the circumference of the bottom surface of the placement plate 201. Each ball 203 is mounted in a ball socket on the bottom surface of the placement plate 201 via a ball retainer, and the lower part of the ball 203 protrudes from the bottom surface of the placement plate 201. Multiple balls 203 are installed in positions corresponding to the annular trajectory of the groove 205. The lower part of the balls 203 is embedded in the groove 205 and rolls in contact with the bottom surface of the groove 205. When the drive motor 210 drives the placement plate 201 to rotate, the balls 203 roll in the groove 205, which not only provides stable rotational support for the placement plate 201 and prevents the placement plate 201 from tilting under the pressure of the mesh, but also greatly reduces the rotational resistance through rolling friction, so that the placement plate 201 can rotate smoothly and steadily.
[0027] like Figure 7 As shown, the edge detection mechanism 3 includes a first linear motor 304, a first support platform 303 fixedly mounted on the upper end of the first linear motor 304, a telescopic mechanism 305 fixedly mounted at the middle position of the upper end of the first support platform 303, a limit frame 307 fixedly mounted on one end of the telescopic mechanism 305, two rollers 306 rotatably mounted inside the limit frame 307, a first data transceiver 301 fixedly mounted on one side of the upper end of the first support platform 303, and a first laser rangefinder 302 fixedly mounted on the other side of the upper end of the first support platform 303.
[0028] Specifically, the mover of the first linear motor 304 is slidably mounted on the slide rail 102 on the surface of the base plate 103 via a slider. The stator of the first linear motor 304 is arranged parallel to the slide rail 102, allowing the first linear motor 304 to precisely reciprocate along the slide rail 102 between the placement mechanism 2 and the edge of the mesh. The first support platform 303 is an L-shaped metal bracket. The lower end of its vertical section is fixedly connected to the upper surface of the mover of the first linear motor 304 by bolts. Its horizontal section extends forward, providing an installation platform for the telescopic mechanism 305, the first data transceiver 301, and the first laser rangefinder 302. The telescopic mechanism 305 is horizontally fixed to the middle position of the upper surface of the horizontal section of the first support platform 303 by bolts. The telescopic direction of the telescopic mechanism 305 faces the central area of the placement mechanism 2. The limiting frame 307 is a U-shaped or rectangular frame structure. Its open end faces the edge of the mesh, and the closed end of the limiting frame 307 is fixedly connected to the telescopic end of the telescopic mechanism 305 by bolts. Two rollers 306 are arranged vertically at intervals. Each roller 306 is rotatably connected to the two side walls of the limiting frame 307 via a pin, and the wheel surface of the roller 306 protrudes from the side of the limiting frame 307 facing the mesh, allowing the roller 306 to roll on the edge surface of the mesh. A first data transceiver 301 is fixed to one side of the upper surface of the horizontal section of the first support platform 303 via a bracket. The first data transceiver 301 is a wireless communication module or a wired communication interface, used to transmit the data signals collected by the ranging sensor 30503 and the first laser rangefinder 302 to the controller 209, and to receive control commands fed back by the controller 209. The first laser rangefinder 302 is fixed to the other side of the upper surface of the horizontal section of the first support platform 303 via a bracket. The laser emitting end of the first laser rangefinder 302 faces the placement mechanism 2 horizontally, used to perform non-contact laser scanning ranging on the edge of the mesh to obtain the precise spatial coordinates of the mesh edge.
[0029] like Figure 8 As shown, the telescopic mechanism 305 includes a telescopic outer rod 30501, a second guide rod 30504 fixedly disposed inside the telescopic outer rod 30501, a telescopic inner rod 30506 slidably disposed on the surface of the second guide rod 30504, a second spring 30505 fixedly disposed between the telescopic outer rod 30501 and the telescopic inner rod 30506, a distance sensor 30503 fixedly disposed on one side inside the telescopic outer rod 30501, and a positioning block 30502 fixedly disposed at one end of the telescopic inner rod 30506.
[0030] Specifically, the telescopic outer rod 30501 is a cylindrical structure closed at one end. Its closed end is fixedly connected to the upper surface of the first support platform 303 via a flange, and the open end of the telescopic outer rod 30501 faces the placement mechanism 2. The second guide rod 30504 is a cylindrical smooth rod. The axis of the second guide rod 30504 coincides with the axis of the telescopic outer rod 30501. One end of the second guide rod 30504 is fixed to the inner wall of the closed end of the telescopic outer rod 30501 by a nut, and the other end extends suspended to the vicinity of the open end of the telescopic outer rod 30501. The telescopic inner rod 30506 is a tubular structure, with its outer diameter matching the inner diameter of the telescopic outer rod 30501. The inner rod 30506 is slidably fitted inside the telescopic outer rod 30501, and its inner hole matches the outer diameter of the second guide rod 30504, allowing the inner rod 30506 to slide smoothly along the second guide rod 30504, ensuring the straightness and stability of the telescopic movement. The second spring 30505 is fitted around the outer circumference of the second guide rod 30504. One end of the second spring 30505 is fixedly connected to the inner wall of the closed end of the telescopic outer rod 30501, and the other end is fixedly connected to the end face of the inner rod 30506 located inside the telescopic outer rod 30501. In the free state, the second spring 30505 is compressed, pushing the inner rod 30506 away from the telescopic outer rod 30501, keeping the inner rod 30506 extended. The ranging sensor 30503 is fixed to the side wall inside the telescopic outer rod 30501 via a bracket. The detection end of the ranging sensor 30503 faces the end face of the positioning block 30502 or the telescopic inner rod 30506, and is used to cooperate with the positioning block 30502 to detect the extension length or retraction displacement of the telescopic inner rod 30506 relative to the telescopic outer rod 30501 in real time. When the contour of the mesh edge changes, the roller 306 pushes the limiting frame 307 and the positioning block 30502, causing the telescopic inner rod 30506 to compress or extend. The ranging sensor 30503 detects the displacement change of the positioning block 30502 in real time, thereby accurately collecting the real-time movement path data of the mesh edge.
[0031] like Figure 9 As shown, the surface polishing mechanism 4 includes a second linear motor 405, a second support platform 404 fixedly mounted on the upper end of the second linear motor 405, a second data transceiver 402 fixedly mounted on one side of the upper end of the second support platform 404, a second laser rangefinder 401 fixedly mounted on the other side of the upper end of the second support platform 404, a first electric telescopic rod 403 fixedly mounted on the upper end of the second support platform 404, a first polishing bracket 408 fixedly mounted on one end of the first electric telescopic rod 403, a second electric telescopic rod 406 fixedly mounted on the upper end of the first polishing bracket 408, and a first polishing head 407 mounted on one end of the second electric telescopic rod 406 and the bottom end of the first polishing bracket 408.
[0032] Specifically, the mover of the second linear motor 405 is slidably mounted on the slide rail 102 on the surface of the base plate 103 via a slider. The stator of the second linear motor 405 is arranged parallel to the slide rail 102, allowing the second linear motor 405 to precisely reciprocate along the slide rail 102 between the placement mechanism 2 and the mesh surface. The second support platform 404 is a flat metal bracket, the lower surface of which is fixedly connected to the upper surface of the mover of the second linear motor 405 by bolts. The upper surface of the second support platform 404 is a horizontal mounting surface. The second data transceiver 402 is fixed to one side of the upper surface of the second support platform 404 by a bracket. The second data transceiver 402 is communicatively connected to the controller 209, used to receive position control commands sent by the controller 209, and to feed back the detection data of the second laser rangefinder 401 to the controller 209. The second laser rangefinder 401 is fixed to the other side of the upper surface of the second support platform 404 via a bracket. The laser emitting end of the second laser rangefinder 401 faces the placement mechanism 2 and is used to detect the distance to the mesh surface before grinding to calibrate the initial grinding position of the first grinding head 407. The cylinder of the first electric telescopic rod 403 is horizontally fixed to the middle position of the upper surface of the second support platform 404 via a flange. The telescopic rod of the first electric telescopic rod 403 faces the placement mechanism 2 and is used to horizontally advance the first grinding bracket 408. The first grinding bracket 408 is an L-shaped metal frame. The lower end of its vertical section is fixedly connected to the end of the telescopic rod of the first electric telescopic rod 403 via a flange, and its horizontal section extends forward. The cylinder of the second electric telescopic rod 406 is vertically fixed to the upper surface of the horizontal section of the first grinding bracket 408 via a flange. The telescopic rod of the second electric telescopic rod 406 is arranged vertically downward and is used to vertically adjust the height position of the first grinding head 407 above. Both first grinding heads 407 are disc grinders. One first grinding head 407 is fixed to the lower end of the vertical section of the first grinding bracket 408 by a bracket, with its grinding surface facing upwards, and is used to grind the upper surface of the mesh horizontally. The other first grinding head 407 is fixed to the lower end of the telescopic rod of the second electric telescopic rod 406 by a bracket, with its grinding surface facing downwards. By adjusting the verticality of the second electric telescopic rod 406, it can grind the upper and lower surfaces of meshes of different thicknesses.
[0033] like Figure 10As shown, the side grinding mechanism 5 includes a third linear motor 505, a third support platform 504 fixedly mounted on the upper end of the third linear motor 505, a third data transceiver 502 fixedly mounted on one side of the upper end of the third support platform 504, a third laser rangefinder 501 fixedly mounted on the other side of the upper end of the third support platform 504, a third electric telescopic rod 503 fixedly mounted on the upper end of the third support platform 504, a second grinding bracket 509 fixedly mounted on one end of the third electric telescopic rod 503, a fourth electric telescopic rod 506 fixedly mounted on the upper end of the second grinding bracket 509, a diagonal support bracket 507 fixedly mounted on one end of the fourth electric telescopic rod 506, and a second grinding head 508 mounted on the surface of the diagonal support bracket 507.
[0034] Specifically, the mover of the third linear motor 505 is slidably mounted on the slide rail 102 on the surface of the base plate 103 via a slider. The stator of the third linear motor 505 is arranged parallel to the slide rail 102, allowing the third linear motor 505 to precisely reciprocate along the slide rail 102 between the placement mechanism 2 and the side of the mesh. The third support platform 504 is a flat metal bracket, the lower surface of which is fixedly connected to the upper surface of the mover of the third linear motor 505 by bolts. The third data transceiver 502 is fixed to one side of the upper surface of the third support platform 504 via a bracket. The third data transceiver 502 is communicatively connected to the controller 209, used to receive position control commands sent by the controller 209, and to feed back the detection data of the third laser rangefinder 501 to the controller 209. The third laser rangefinder 501 is fixed to the other side of the upper surface of the third support platform 504 via a bracket. The laser emitting end of the third laser rangefinder 501 faces the placement mechanism 2 and is used to detect the distance and angle of the side of the mesh before grinding to calibrate the initial grinding position of the second grinding head 508. The cylinder of the third electric telescopic rod 503 is horizontally fixed to the middle position of the upper surface of the third support platform 504 via a flange. The telescopic rod of the third electric telescopic rod 503 faces the placement mechanism 2 and is used to horizontally advance the second grinding bracket 509. The second grinding bracket 509 is a rectangular metal frame, and its lower end is fixedly connected to the end of the telescopic rod of the third electric telescopic rod 503 via a flange. The cylinder of the fourth electric telescopic rod 506 is obliquely fixed to the upper end of the second grinding bracket 509 via a hinge seat. The telescopic rod of the fourth electric telescopic rod 506 is arranged obliquely downward, and its extension direction is arranged at an angle to the extension direction of the third electric telescopic rod 503. The inclined support bracket 507 is an inclined metal plate or metal rod. Its upper end is connected to the telescopic rod end of the fourth electric telescopic rod 506 via a hinge seat. The middle or lower end of the inclined support bracket 507 is hinged to the middle of the second grinding bracket 509 via a hinge shaft, so that the inclined support bracket 507 forms a lever structure with the second grinding bracket 509 as the fulcrum. The second grinding head 508 is a disc grinder, which is fixed to the lower end surface of the inclined support bracket 507 via a bracket. The grinding surface of the second grinding head 508 faces the side of the mesh. By the horizontal advancement of the third electric telescopic rod 503, the second grinding head 508 can move closer to or further away from the side of the mesh; by the telescopic adjustment of the fourth electric telescopic rod 506, the inclined support bracket 507 moves up and down, so that the second grinding head 508 can grind meshes of different thicknesses.
[0035] Working principle: First, the operator horizontally hoists or transports the fence mesh to be ground to above the placement plate 201, aligning the positioning protrusions on the bottom surface of the mesh with the positioning holes 202 on the upper surface of the placement plate 201, so that the mesh is stably placed on the placement plate 201, achieving the initial placement of the mesh. Subsequently, the operator issues a clamping command through the controller 209, which controls the solenoid valve of the hydraulic cylinder 106 to actuate, causing the piston rod of the hydraulic cylinder 106 to extend downward, pushing the rotating shaft 108 and the upper pressure plate 109 to move downward as a whole. Multiple positioning pins 112 on the bottom surface of the upper pressure plate 109 move down synchronously with the upper pressure plate 109. If the lower end of the positioning pin 112 is aligned with the positioning hole 202 on the placement plate 201, the positioning pin 112 is inserted into the positioning hole 202 under the elastic thrust of the first spring 111, realizing precise circumferential positioning between the upper pressure plate 109 and the placement plate 201, thereby firmly locking the mesh on the placement plate 201 and preventing the mesh from shifting circumferentially during subsequent rotation and grinding. If the lower end of the positioning pin 112 is not aligned with the positioning hole 202 and is blocked by the steel wire solid part of the mesh, the positioning pin 112 is subjected to the upward reaction force of the mesh, slides upward along the first guide rod 110 and compresses the first spring 111, causing the positioning pin 112 to elastically retract into the guide hole of the upper pressure plate 109, avoiding the positioning pin 112 from forcibly piercing the mesh and causing damage to the mesh. When the hydraulic cylinder 106 reaches the set pressure, it stops pressing down. At this time, the mesh is clamped tightly by the upper pressure plate 109 and the placement plate 201. Due to the elasticity of the positioning pin 112, the mesh will not deform due to rigid clamping. At the same time, since the rotating shaft 108 is rotatably connected to the hydraulic cylinder 106 through the bearing 107, the upper pressure plate 109 can rotate synchronously with the placement plate 201.
[0036] The controller 209 starts the first linear motor 304, which moves along the slide rail 102 towards the edge of the mesh until the two rollers 306 inside the limiting frame 307 contact the edge of the mesh. Under the elastic thrust of the second spring 30505, the telescopic inner rod 30506 extends along the second guide rod 30504, keeping the rollers 306 elastically against the side of the mesh edge. At this time, the ranging sensor 30503 aligns with the positioning block 30502, detects the initial extension position of the telescopic inner rod 30506 in real time, and transmits the initial position data to the controller 209 through the first data transceiver 301 to establish the initial reference for edge detection.
[0037] The controller 209 starts the drive motor 210, and the output shaft of the drive motor 210 drives the placement plate 201 to rotate at a constant speed. The balls 203 on the bottom surface of the placement plate 201 roll in the grooves 205 of the lower support 204, providing low-resistance rotational support for the placement plate 201. The mesh rotates synchronously with the placement plate 201. The contour changes of the mesh edge drive the rollers 306 and the limiting frame 307 to move, which in turn drives the telescopic inner rod 30506 to reciprocate along the second guide rod 30504 through the positioning block 30502. The distance sensor 30503 detects the displacement changes of the positioning block 30502 in real time, that is, the real-time movement path data of the mesh edge relative to the initial reference, and continuously transmits the real-time path data to the controller 209 through the first data transceiver 301.
[0038] The controller 209 receives real-time displacement data transmitted by the ranging sensor 30503 and converts the telescopic displacement of the positioning block 30502 into real-time contour coordinates of the mesh edge using a built-in algorithm. Based on these real-time contour coordinates, the controller 209 synchronously outputs control commands to the surface grinding mechanism 4 and the side grinding mechanism 5: the controller 209 controls the real-time telescopic extension and retraction of the first electric telescopic rod 403 via the second data transceiver 402, so that the horizontal position of the first grinding bracket 408 and the first grinding head 407 always follows the contour change of the mesh edge; at the same time, the controller 209 controls the real-time telescopic extension and retraction of the third electric telescopic rod 503 via the third data transceiver 502, so that the horizontal position of the second grinding bracket 509 and the second grinding head 508 synchronously follows the contour change of the mesh edge. During this process, the second laser rangefinder 401 and the third laser rangefinder 501 perform auxiliary distance measurement on the surface and side of the mesh, respectively, and feed back the actual distance between the first grinding head 407 and the second grinding head 508 and the mesh to the controller 209. The controller 209 combines the path data of the distance sensor 30503 and the feedback data of the laser rangefinders to perform closed-loop correction on the extension and retraction of the first electric telescopic rod 403 and the third electric telescopic rod 503, so as to ensure that the first grinding head 407 and the second grinding head 508 always maintain a constant grinding distance and grinding pressure with the edge of the mesh.
[0039] During the rotation of the mesh, the first grinding head 407 and the second grinding head 508 remain operational. The first grinding head 407 performs rotational grinding on the upper surface of the mesh, and its horizontal position is continuously adjusted by the first electric telescopic rod 403 based on real-time path data. The second grinding head 508 performs rotational grinding on the side of the mesh, and its horizontal position is continuously adjusted by the third electric telescopic rod 503 based on real-time path data. Simultaneously, the fourth electric telescopic rod 506 adjusts the position of the inclined support bracket 507 based on feedback from the third laser rangefinder 501, ensuring that the grinding surface of the second grinding head 508 always conforms to the actual angle of the side of the mesh. Since the roller 306 of the edge detection mechanism 3 always conforms to the edge of the mesh, the distance sensor 30503 and the positioning block 30502 work together to achieve real-time acquisition of the movement path of the mesh edge. The controller 209 synchronously controls the first electric telescopic rod 403 and the third electric telescopic rod 503 based on this real-time path, so that the grinding mechanism and the edge detection mechanism 3 form a closed-loop follow-up system, ensuring accurate following and grinding of the mesh edge.
[0040] Driven by the placement plate 201, the mesh sheet rotates continuously. The rollers 306 of the edge detection mechanism 3 roll along the four edges of the mesh sheet. The distance sensor 30503 continuously collects path data of the entire circumferential edge. The controller 209 synchronously controls the surface grinding mechanism 4 and the side grinding mechanism 5 to complete the continuous grinding of the four edges of the mesh sheet. During this process, the controller 209 continuously starts the vacuum cleaner 104. The vacuum cleaner 104 generates a negative pressure suction airflow in the grinding area through the suction head 105, which promptly absorbs and collects the metal dust and debris generated during grinding, preventing dust diffusion. Since the upper pressure plate 109 is rotatably connected to the hydraulic cylinder 106 through the bearing 107, and the cooperation between the positioning pin 112 and the positioning hole 202 effectively prevents the circumferential movement of the mesh sheet, the upper pressure plate 109 can rotate stably and synchronously with the mesh sheet, ensuring the fixed stability of the mesh sheet throughout the entire circumferential grinding process.
[0041] After the mesh has rotated one revolution and all edges have been polished, the controller 209 stops the drive motor 210, stops the first polishing head 407 and the second polishing head 508, and retracts the first and third electric telescopic rods 403 and 503, moving the polishing mechanism away from the mesh. Then, the controller 209 retracts the piston rod of the hydraulic cylinder 106, causing the upper pressure plate 109 and the positioning pin 112 to disengage from the positioning hole 202 and the mesh surface. The operator then removes the polished mesh from the placement plate 201, completing one work cycle.
