TECHNICAL FIELD
[0001] The present application relates to the technical field of electric vehicle processing, more particularly to an edge deburring device for a front lamp cover of an electric vehicle. BACKGROUND
[0002] As a key component of the lighting system of an electric vehicle, the front lamp cover of the electric vehicle is usually manufactured by injection molding. However, burrs and flash are often generated on the edge of the lamp cover after injection molding, which not only affects the appearance quality of the lamp cover, but also may scratch the operator during the subsequent assembly process, and even cause the burrs to fall off due to vibration during the driving of the vehicle, thereby affecting the normal use performance and safety of the vehicle lamp.
[0003] At present, the burrs on the edge of the front lamp cover of the electric vehicle are usually removed by manually holding sandpaper, a file or a grinder, which not only has high labor intensity and low production efficiency, but also has a large influence on the deburring effect due to the experience and skill level of the operator, and it is difficult to ensure the consistency of product quality.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Reference Figures 1-14 This invention provides an edge deburring device for electric vehicle headlight covers, including a frame 1 for mounting and supporting components. An installation platform 301 is fixedly mounted on the frame 1 by bolts, and a clearance groove 302 is provided at the bottom. A rotary positioning module 2 is provided above the frame 1, which is used to drive the headlight cover to change positions and rotate. A pressing positioning module 3 is provided behind the rotary positioning module 2 and mounted on the frame 1. The pressing positioning module 3 is used to adjust and limit the angle of the headlight cover placed on the rotary positioning module 2. A pressing fixing module 4 is provided above the rotary positioning module 2 and mounted on the frame 1. The rotary positioning module 2 is used to fix the headlight cover and can adjust the angle of the headlight cover in cooperation with the pressing positioning module 3. An edge processing module 5 is provided behind the pressing positioning module 3 and is used to deburr the inner and outer edges of the headlight cover.
[0036] Based on the above, the simple steps for deburring lampshades are as follows: First, the staff places the lampshade to be processed into the rotary transposition module 2, which will move the lampshade to the edge processing module 5. Subsequently, the pressing and fixing module 4 and the pressing and positioning module 3 work together to adjust the angle of the lamp cover placed on the rotating and shifting module 2, so that the lamp cover is in a horizontal position. Once the lampshade is in a horizontal position, use the pressing fixing module 4 and the pressing positioning module 3 to fix the current position of the lampshade, ensuring that the lampshade can always remain in a horizontal position. Subsequently, the edge processing module 5 polishes the edges of the lampshade. At the same time, the rotation module 2 drives the lampshade to rotate, thereby completing the burr removal work around the lampshade. The edge processing module 5 adjusts the polishing angle to achieve burr removal on the inner and outer sides of the lampshade. After the burrs on the inner and outer sides of the lampshade are removed, each module is reset, and the rotating module 2 is rotated to move the lampshade away from the edge processing module 5, so that the lampshade can be removed, completing one lampshade deburring operation.
[0037] Throughout the process, staff only need to perform loading and unloading operations, which greatly reduces labor intensity. At the same time, the precise coordination of the mechanical structure ensures that the deburring effect of each lampshade is uniform and consistent, effectively improving production efficiency and product quality stability.
[0038] The following is a detailed introduction to each module: Among them, reference Figures 3-5 The rotary positioning module 2 includes an upper guide rail 203 fixedly installed on the frame 1. A slide 202 is slidably installed on the upper part of the guide rail 203. The slide 202 can enter the clearance groove 302 opened at the bottom of the mounting platform 301. A first motor 207 is fixedly installed below the slide 202. The output shaft of the first motor 207 passes through the slide 202 and a placement seat 206 is fixedly installed. The placement seat 206 can be driven to rotate by the first motor 207, thereby driving the lampshade to rotate, thus changing the polishing position of the lampshade. A first cylinder 201 is fixedly installed below the mounting platform 301. The movable end of the first cylinder 201 is fixed to the slide 202. The extension and retraction of the first cylinder 201 can drive the slide 202 to move on the guide rail 203, thereby changing the position of the lampshade on the frame 1. Specifically, when the lampshade to be processed needs to be placed on the placement seat 206, the first cylinder 201 is in the extended state, and the slide 202 is located at the end of the guide rail 203 away from the edge processing module 5, which facilitates the staff to perform the loading operation.
[0039] After the material is loaded, the movable end of the first cylinder 201 retracts, pulling the slide 202 along the guide rail 203 toward the edge processing module 5 until the slide 202 enters the clearance groove 302 at the bottom of the mounting platform 301. At this time, the lamp cover is transported to the working area directly below the edge processing module 5, preparing for subsequent positioning, fixing and deburring operations.
[0040] During the deburring process, when the edge processing module 5 polishes the lampshade, the first motor 207 starts, driving the placement seat 206 to rotate at a constant speed. The placement seat 206 then drives the lampshade on it to rotate synchronously, so that the entire circumference of the lampshade can pass through the polishing unit of the edge processing module 5 in sequence, achieving continuous and uniform processing of the circumference of the lampshade.
[0041] After a round of grinding is completed, the first motor 207 stops rotating. If the lampshade needs to be moved out of the work area, the movable end of the first cylinder 201 extends, pushing the slide 202 and the placement seat 206 back to the initial loading position, so that the workers can take out the finished lampshade and place the new lampshade to be processed.
[0042] Through the coordinated movement of the first cylinder 201 and the rotation of the first motor 207, the rotary transfer module 2 not only realizes the precise transfer of the lampshade between the loading / unloading station and the processing station, but also provides stable rotational support for the edge processing module 5 to perform all-round, no-dead-angle grinding on the edge of the lampshade, effectively ensuring the continuity and uniformity of the grinding operation.
[0043] Among them, reference Figure 3 , Figures 6-9 The pressing positioning module 3 includes two movable rods 304 slidably mounted on the front end of the mounting platform 301. A T-shaped guide rail is provided at the front end of the platform 301, and a T-shaped guide groove is provided on the movable rod 304 to cooperate with the guide rail. The T-shaped guide rail and the T-shaped guide groove together guide and limit the horizontal movement of the movable rod 304. A tension spring 305 is fixedly installed between the movable rod 304 and the mounting platform 301. The tension spring 305 can pull the movable rod 304 to reset, so that the opposite sides of the two movable rods 304 contact the slide 202. The tension spring 305 is detachable and can be replaced. In addition, a locking component is provided between the moving rod 304 and the slide 202 to fix the position of the moving rod 304. When the slide 202 is completely in the clearance groove 302, the moving rod 304 is locked so that the moving rod 304 cannot move. Specifically, such as Figure 8 As shown, the locking assembly includes slots 306 opened on opposite sides of the two moving rods 304, and brackets 204 fixedly installed on both sides of the front end of the carriage 202. The brackets 204 are in special shapes such as "T", "L" or trapezoidal that can hook the slots 306. When the carriage 202 is completely in the clearance slot 302, the brackets 204 are completely in the slots 306. As the slide 202 moves along the guide rail 203 toward the edge processing module 5, the brackets 204 on both sides of the front end of the slide 202 will gradually approach the slots 306 on the opposite side of the moving rod 304. When the slide 202 is fully inserted into the clearance slot 302, the brackets 204 are fully embedded in the slots 306. At this time, the moving rod 304 is hooked by the brackets 204, thereby locking the position of the moving rod 304 and preventing it from sliding freely on the mounting platform 301.
[0044] This locking method has a simple and reliable structure, which can ensure that the moving rod 304 remains stable during subsequent positioning and grinding operations, providing a basis for the precise positioning of the lampshade.
[0045] When the carriage 202 needs to exit the clearance groove 302, the movable end of the first cylinder 201 extends, pushing the carriage 202 to move away from the edge processing module 5. At this time, the bracket 204 will disengage from the slot 306, releasing the lock on the moving rod 304.
[0046] In addition, such as Figure 3 and Figure 4 As shown, both sides of the front end of the carriage 202 are inclined surfaces 205. There is a gap between the front end of the inclined surface 205 and the moving rod 304. The gap is not less than the length of the bracket 204. Please refer to [reference needed]. Figure 8 At least two mounting slots 308 are provided on the opposite sides of the two moving rods 304. An auxiliary roller 307 is rotatably mounted in the mounting slot 308. As the slide 202 moves away from the edge processing module 5, the inclined surface 205 will squeeze the last auxiliary roller 307, forcing the two moving rods 304 to slide away from each other against the tension of the tension spring 305, making room for the slide 202 to exit smoothly. At this time, the slide 202 will continuously block the resetting of the moving rods 304.
[0047] Furthermore, during the movement of the carriage 202, the auxiliary roller 307 can reduce the friction between the moving rod 304 and the carriage 202, reduce wear between the two, and extend the service life of the equipment.
[0048] As the slide 202 re-enters the recess 302, the slide 202 will gradually lose its obstruction of the moving rod 304. Under the action of the tension spring 305, the two moving rods 304 will slide back to their original positions in the direction of mutual approach until their opposite sides contact the front end face of the slide 202. At this time, as the slide 202 continues to move, the holder 204 can smoothly enter the slot 306 and complete the locking.
[0049] This design makes the reset process of the moving rod 304 smooth and automated, requiring no manual intervention, further improving the automation level and ease of operation of the equipment.
[0050] Furthermore, refer to Figure 6 and Figure 9Multiple fixing rods 303 are fixedly installed above the mounting platform 301 and the moving rod 304. The multiple fixing rods 303 are evenly distributed around the rotation axis of the placement seat 206, which can evenly press down on the lamp cover and facilitate the adjustment of the lamp cover angle. A rotating frame 310 is rotatably mounted on the top of the fixed rod 303. A lower pressure roller 311 is rotatably mounted on the end of the rotating frame 310 near the placement seat 206 via a shaft. When the lower pressure roller 311 presses down, it will contact the top edge of the lampshade. An electric push rod 309 is rotatably mounted on the side of the fixed rod 303 near the rotating frame 310. The movable end of the electric push rod 309 is rotatably connected to the rotating frame 310. The retraction of the electric push rod 309 can drive the rotating frame 310 to rotate. A limit block 312 is fixedly mounted on the side of the fixed rod 303 near the placement seat 206. The limit block 312 can limit the extreme position of the rotating frame 310. This extreme position is when the lampshade is in a horizontal state, and the lower pressure roller 311 contacts the lampshade and exerts a small downward pressure on the lampshade (this downward pressure will not damage the lampshade, but only slightly presses down on the lampshade). Specifically, when the slide 202 moves the lamp cover to directly below the working area of the edge processing module 5, the electric push rod 309 on the fixed rod 303 starts and retracts, and its movable end pulls the rotating frame 310 to rotate downward around the connecting shaft at the top of the fixed rod 303. As the rotating frame 310 rotates, the lower pressure roller 311 installed on the end of the rotating frame 310 near the placement seat 206 gradually approaches the top edge of the lampshade; After the lower pressure roller 311 contacts the top edge of the lampshade, the electric push rod 309 continues to apply a certain pulling force, so that the lower pressure roller 311 exerts downward pressure on the edge of the lampshade, thereby adjusting the angle of the lampshade or pressing it down to fix it.
[0051] When it is necessary to press down and fix the lampshade, since multiple fixing rods 303 are evenly distributed around the rotation axis of the placement seat 206, multiple pressing rollers 311 can apply pressure simultaneously from multiple symmetrical points on the top edge of the lampshade. If there is a slight angular deviation when the lampshade is initially placed, the lampshade will be adjusted on the placement seat 206 under the pressure of the lower pressure roller 311 at the raised end until all the lower pressure rollers 311 are in close contact with the edge of the lampshade (the rotation angle of all the rotating frames 310 is fixed). At this time, the lampshade is adjusted to a horizontal state, and the angle is limited by the lower pressure roller 311, ensuring that the axis of the lampshade remains vertical and the edge is within the preset processing plane during the subsequent rotational grinding process.
[0052] By having multiple pressure rollers 311 roll into contact with the edge of the lampshade, a stable downward pressure can be provided, and the rollers can rotate synchronously with the lampshade during the rotation and polishing process, thus avoiding secondary damage such as scratches or indentations on the surface of the lampshade.
[0053] It should be noted that the electric push rod 309, in conjunction with a magnetic switch or proximity switch, enables precise control of the push rod's extension and retraction displacement. Those skilled in the art can configure it according to actual needs.
[0054] Furthermore, refer to Figure 2 and Figure 4 Multiple support frames 6 are fixedly installed on the top of the mounting platform 301 and the slide 202 by bolts. Support rollers 7 are rotatably installed on the top of the support frame 6. The outer circumference of the support roller 7 is in line contact with the lamp cover. The multiple support rollers 7 cooperate with the pressing positioning module 3 to clamp and position the lamp cover.
[0055] When the pressure roller 311 of the pressure positioning module 3 applies downward pressure to the top edge of the lampshade, the support rollers 7 at the top of the multiple supports 6 on the placement seat 206 provide upward support from the bottom of the lampshade. These support rollers 7 are also evenly distributed circumferentially around the rotation axis of the placement seat 206, corresponding one-to-one with the pressure roller 311 above, together forming a stable clamping and positioning system.
[0056] Specifically, when the lampshade is placed on the placement seat 206, its bottom edge will contact the outer circumference of the support roller 7. During the process of the electric push rod 309 driving the pressure roller 311 to press down, the lampshade is subjected to downward pressure, which makes its bottom edge fit tightly against the support roller 7.
[0057] Since the contact between the support roller 7 and the lampshade is a line contact, it can provide sufficient support to resist the pressure of the lower roller 311, and minimize the contact area with the bottom of the lampshade, thereby reducing the risk of indentation on the bottom surface of the lampshade.
[0058] At the same time, this line contact combined with the rotational performance of the support roller 7 allows the support roller 7 to rotate freely with the lampshade when the rotary positioning module 2 drives the lampshade to rotate for grinding operations. This transforms the sliding friction between the two into rolling friction, significantly reducing friction and ensuring the smooth rotation of the lampshade. It also avoids problems such as wear on the lampshade surface or affecting rotational accuracy due to excessive friction.
[0059] Through the combined action of the downward pressure applied from above by the pressure roller 311 and the support force provided from below by the support roller 7, the lampshade is firmly clamped in the preset horizontal processing position, and its central axis is highly coincident with the rotation axis of the placement seat 206, laying a solid positioning foundation for the edge processing module 5 to perform precise and uniform deburring operations.
[0060] Among them, reference Figure 10 and Figure 11The pressing and fixing module 4 includes two mounting plates 401 fixedly installed on the top of the frame 1. A lifting frame 403 is slidably installed between the two mounting plates 401. A support base is fixed in the middle of the lifting frame 403. The base of the support base is rotatably mounted with a connecting frame 404 through a bearing. An elastic rubber block 405 is bonded to the bottom of the connecting frame 404. When the connecting frame 404 moves downward, the elastic rubber block 405 at the bottom will come into contact with the lampshade, thereby squeezing the lampshade and applying uniform pressure to the top center area of the lampshade, further enhancing the stability of the lampshade during the rotation and polishing process.
[0061] A second cylinder 402 is fixedly installed on the outer side of one of the mounting plates 401. The movable end of the second cylinder 402 is fixed to the lifting frame 403. The extension and retraction of the second cylinder 402 can drive the lifting frame 403 to slide up and down along the mounting plate 401.
[0062] Specifically, after the rotary positioning module 2 transports the lampshade to the processing station and the angle is adjusted by the pressing positioning module 3, the pressing fixing module 4 begins to work.
[0063] The movable end of the second cylinder 402 extends downward, pushing the lifting frame 403 to move downward along the mounting plate 401, and the connecting frame 404 moves downward together with the lifting frame 403. When the elastic rubber block 405 at the bottom of the connecting bracket 404 contacts the center of the top of the lampshade, the second cylinder 402 continues to extend, causing the elastic rubber block 405 to undergo elastic deformation, thereby applying a gentle and stable downward pressure to the top of the lampshade, ensuring that the lampshade can be rotated by the placement seat 206. Because the elastic rubber block 405 has good elasticity and friction, it can effectively prevent the lampshade from axial movement or circumferential slippage during rotation, and also avoid damage to the lampshade surface due to rigid contact. The rotating connection design between the connecting frame 404 and the lifting frame 403 allows the elastic rubber block 405 to rotate along with the lamp cover; After the deburring operation is completed, the movable end of the second cylinder 402 retracts, driving the lifting frame 403, connecting frame 404 and elastic rubber block 405 to return to their original position, releasing the fixation of the lamp cover, so that the rotating shifting module 2 can move the processed lamp cover out. Through the precise extension and retraction control of the second cylinder 402, the pressing and fixing module 4 can provide a continuous and appropriate fixing force for the lamp cover during the processing stage, forming a synergistic effect with the pressing and positioning module 3 to firmly fix the lamp cover in the preset processing position, laying a solid foundation for the precise operation of the edge processing module 5.
[0064] By using a dual fixing method, the coaxiality and stability of the lampshade during rotation and polishing are ensured, while minimizing potential damage to the lampshade surface.
[0065] It should be noted that both the first cylinder 201 and the second cylinder 402 are power actuators that convert the pressure energy of compressed air into mechanical energy. They are connected to external air pipes and solenoid valves and drive the piston to perform linear reciprocating motion by controlling the gas inlet and outlet. In conjunction with magnetic switches, proximity switches or photoelectric switches, they can achieve precise control of the extension and retraction displacement of the cylinder piston rod. Those skilled in the art can set them according to actual needs.
[0066] In addition, detection components are provided on opposite sides of the two mounting plates 401 to detect the angle of the lampshade. The detection components include two infrared emitters 407 fixedly installed on the inner side of one of the mounting plates 401 and two infrared receivers 406 fixedly installed on the inner side of the other mounting plate 401. When the lampshade is in a horizontal state, the infrared receivers 406 can receive the infrared rays emitted by the infrared emitters 407.
[0067] Through the coordinated operation of two sets of infrared transmitters 407 and infrared receivers 406, the horizontal status of the lampshade can be monitored in real time. The infrared transmitters 407 can be near-infrared light-emitting diodes with wavelengths of 850nm or 940nm, which emit infrared light with good linear propagation and anti-interference capabilities. The infrared receivers 406 can be matched with phototransistors or photodiodes, which can convert the received infrared light signals into electrical signals and feed them back to the control system of the equipment.
[0068] Two sets of infrared transmitters 407 and infrared receivers 406 are symmetrically arranged on both sides of the central axis of the lampshade, and are located at the same horizontal height, which is slightly higher than the height of the top edge of the lampshade when it is horizontal (e.g., Figure 14 (as shown) Specifically, when the lampshade is adjusted to a horizontal state by the pressing positioning module 3, the two sets of infrared rays can be transmitted from the infrared transmitter 407 to the infrared receiver 406 without obstruction.
[0069] At this time, the infrared receiver 406 receives the complete infrared signal and feeds the signal back to the control system of the equipment, indicating that the lampshade is at the correct processing angle and the pressing and fixing module 4 can proceed to the next fixing action.
[0070] If the lampshade is not level, its edges will block part or all of the infrared light, causing the infrared receiver 406 to be unable to receive a complete signal or to receive no signal at all. The control system will then instruct the positioning module 3 to readjust the angle of the lampshade until the detection component confirms that the lampshade is level, thereby further ensuring the accuracy and reliability of the lampshade positioning and avoiding poor polishing effect or damage to the lampshade due to angle deviation.
[0071] Among them, reference Figure 12 and Figure 13The edge processing module 5 includes a fixed frame 501 fixedly installed on the frame 1. A three-axis linear module 502 is fixedly installed on the fixed frame 501. The three-axis linear module 502 is existing technology. It is mainly composed of an X-axis slide, a Y-axis slide and a Z-axis slide orthogonally combined. Each axis slide is equipped with a high-precision servo motor and a precision ball screw, which can realize independent or linked movement along the X, Y and Z directions. The motion positioning accuracy can reach ±0.01mm and the repeatability positioning accuracy is ±0.005mm, which can meet the processing requirements of complex trajectories of the lampshade edge. The specific structure and principle will not be described in detail.
[0072] The movable end of the three-axis linear module 502 is fixedly mounted with a mounting bracket 503. The bottom end of the mounting bracket 503 is movably mounted with a ball joint 508. A third motor 507 is fixedly mounted inside the ball joint 508. The output shaft of the third motor 507 is mounted with a grinding head 510 through a drill chuck. When it is necessary to deburr the edge of the lampshade, the three-axis linear module 502 drives the mounting bracket 503 to move precisely in the X, Y, and Z directions according to the preset processing parameters, and adjusts the spatial position of the grinding head 510 so that it is aligned with the edge area of the lampshade to be processed.
[0073] The ball joint 508 allows the third motor 507 and the grinding head 510 to be flexibly adjusted at multiple angles, ensuring that the axis of the grinding head 510 matches the tangential direction of the lampshade edge or the preset grinding angle, so as to meet the grinding needs of the inner and outer edges of the lampshade.
[0074] After the third motor 507 starts, it drives the grinding head 510 to rotate at high speed through the output shaft. The abrasive on the surface of the grinding head 510 is used to cut or grind the burrs and flash on the edge of the lampshade.
[0075] To meet the requirements for burr removal on the inner and outer edges of the lampshade, a second motor 504 is fixedly installed at the top of the mounting bracket 503. The second motor 504 can be replaced with a servo motor. The output shaft of the second motor 504 passes through the mounting bracket 503 and a turntable 505 is fixedly installed thereon. A connecting rod 506 is eccentrically fixed at the bottom of the turntable 505. The connecting rod 506 is fixed to the third motor 507. When the angle of the grinding head 510 needs to be adjusted to fit the inner or outer edge of the lampshade, the second motor 504 starts, and its output shaft drives the turntable 505 to rotate.
[0076] Since the connecting rod 506 is eccentrically fixed at the bottom of the turntable 505, the rotation of the turntable 505 will drive the third motor 507 to swing around the ball-shaped connecting seat 508 as the center through the connecting rod 506.
[0077] This eccentric drive method enables continuous and smooth adjustment of the grinding head 510 within a certain angle range, thereby precisely controlling the contact angle and pressure between the grinding head 510 and the edge of the lampshade.
[0078] For example, when grinding the inner edge of the lampshade, the second motor 504 drives the turntable 505 to rotate at a specific angle, and the connecting rod 506 causes the grinding head 510 to tilt inward, so that its axis is consistent with the tangent direction of the inner edge; while when grinding the outer edge, the turntable 505 is rotated in the opposite direction to cause the grinding head 510 to tilt outward.
[0079] This multi-angle adjustable design greatly enhances the adaptability of the edge processing module 5 to the edges of lampshades with different curvatures, ensuring the complete removal of burrs from all parts of the lampshade.
[0080] It should be noted that both the first motor 207 and the second motor 504 are servo motors used in conjunction with the encoder, and their rotation number and rotation angle are controllable. Further details will not be provided here.
[0081] Furthermore, in order to handle the debris generated during polishing, a suction pipe 509 is fixedly installed on one side of the third motor 507. The suction pipe 509 is connected to an external vacuum cleaner. When the vacuum cleaner is started, the suction pipe 509 generates negative pressure to absorb the debris generated during polishing by the polishing head 510. Specifically, the suction port of the suction tube 509 is designed to be tilted towards the grinding area of the grinding head 510, and its position is precisely adjusted to ensure that the suction port can get as close as possible to the source of debris during the grinding operation.
[0082] When the grinding head 510 rotates at high speed to grind the edge of the lampshade, the plastic debris produced will be carried up by the high-speed rotating grinding head 510 or scattered into the surrounding air. At this time, the external vacuum cleaner continuously generates a strong negative pressure airflow through the suction tube 509, which quickly sucks these suspended debris into the suction tube 509 and eventually collects them. This method of removing debris simultaneously with grinding not only effectively prevents debris accumulation in the grinding area from affecting grinding precision and results, and prevents debris from being carried into subsequent processes and causing secondary pollution or scratches to the lamp cover, but also maintains a clean working environment, reduces the risk of operators inhaling debris, and improves the safety and environmental friendliness of equipment operation. At the same time, it also reduces the time cost of frequent shutdowns for cleaning due to debris accumulation, and improves overall processing efficiency.
[0083] The present invention is used in the following steps: S1: First, place the lampshade on the placement seat 206. The movable end of the first cylinder 201 retracts, pulling the slide 202 along the guide rail 203 toward the edge processing module 5 until the slide 202 enters the clearance groove 302 at the bottom of the mounting platform 301. S2: During this process, the slide 202 will gradually lose its obstruction to the moving rod 304. Under the action of the tension spring 305, the two moving rods 304 will slide back to their original positions in the direction of mutual approach until the opposite sides of the moving rods 304 cross the inclined plane 205 and contact the front end face of the slide 202. At this time, as the slide 202 continues to move, the bracket 204 can smoothly enter the slot 306 and complete the locking. S3: Subsequently, the horizontal status of the lampshade is monitored by the coordinated operation of two sets of infrared transmitters 407 and infrared receivers 406. S4: If the lampshade is not horizontal, its edge will block part or all of the infrared light, causing the infrared receiver 406 to be unable to receive a complete signal or to receive no signal. At this time, the electric push rod 309 on the side that does not receive a signal is activated. The movable end of the electric push rod 309 retracts, pulling the rotating frame 310 and the lower pressure roller 311 downward to apply additional downward pressure to the corresponding position of the top edge of the lampshade. S5: As the support roller 7 at the corresponding position at the bottom of the lampshade provides an upward support force, under the action of the lower pressure roller 311 on this side, the lampshade will tilt slightly to this side around its central axis, thereby adjusting the overall horizontal angle. S6: During this process, the infrared transmitter 407 and the infrared receiver 406 continue to work. If both sets of infrared receivers 406 can receive complete signals after adjustment, it indicates that the lampshade has been adjusted to a horizontal state, and the electric push rod 309 stops moving. If it is still not horizontal, it continues to be finely adjusted by the electric push rod 309 on the corresponding side until the detection component confirms that the lampshade is horizontal. S7: Then all the electric push rods 309 are activated so that the rotating frame 310 rotates to the same angle. At this time, all the lower pressure rollers 311 are in close contact with the edge of the lampshade, forming a stable clamping and positioning system together with the support roller 7. S8: The movable end of the second cylinder 402 extends downward, pushing the lifting frame 403 to move downward along the mounting plate 401. The connecting frame 404 moves downward along with the lifting frame 403. When the elastic rubber block 405 at the bottom of the connecting frame 404 contacts the center of the top of the lampshade, the second cylinder 402 continues to extend, causing the elastic rubber block 405 to undergo elastic deformation, thereby applying a soft and stable downward pressure to the top of the lampshade, ensuring that the lampshade can be rotated by the placement seat 206. S9: The three-axis linear module 502 drives the mounting bracket 503 to move precisely in the X, Y, and Z directions according to the preset processing parameters, and adjusts the spatial position of the grinding head 510 so that it is aligned with the edge area of the lampshade to be processed. S10: Simultaneously start the first motor 207 and the third motor 507. After the third motor 507 starts, it drives the grinding head 510 to rotate at high speed through the output shaft. The abrasive on the surface of the grinding head 510 is used to cut or grind the burrs and flash on the edge of the lampshade. After the first motor 207 starts, it drives the placement seat 206 to rotate at a constant speed. The placement seat 206 then drives the lampshade on it to rotate synchronously, so that the entire circumference of the lampshade can pass through the grinding head 510 of the edge processing module 5 in sequence to complete the burr treatment of one side of the lampshade. Then, the first motor 207 and the third motor 507 stop working, the grinding head 510 stops rotating, and the lampshade also stops rotating. S11: During the deburring process, the external vacuum cleaner continuously generates a strong negative pressure airflow through the suction pipe 509, which quickly sucks the suspended debris into the suction pipe 509 and eventually collects it. S12: When it is necessary to adjust the angle of the grinding head 510 to adapt to the inner or outer edge of the lampshade, the second motor 504 starts, and its output shaft drives the turntable 505 to rotate. The rotation of the turntable 505 will drive the third motor 507 to swing around the ball joint 508 as the center through the connecting rod 506, thereby causing the grinding head 510 to deflect to the other side of the lampshade. During this process, the three-axis linear module 502 will also drive the grinding head 510 to move up and down to avoid the lampshade. S13: Repeat step S10 to complete the burr treatment on the other side of the lampshade, and then complete the burr treatment on both sides of the lampshade. S14: Subsequently, the movable end of the second cylinder 402 retracts, driving the lifting frame 403, connecting frame 404 and elastic rubber block 405 to return to their original position, releasing the fixing pressure on the center of the top of the lampshade. Then, the movable ends of all the electric push rods 309 extend, pushing the rotating frame 310 and the lower pressure roller 311 to move upward, releasing the clamping on the top edge of the lampshade. S15: Then, the movable end of the first cylinder 201 extends and pushes the slide 202 to move away from the edge processing module 5 along the guide rail 203. During this process, the front end of the slide 202 will push the moving rod 304 to slide away from each other against the tension of the tension spring 305, so that the card holder 204 disengages from the card slot 306 and the locking state is released. S16: After the slide 202 moves the placement seat 206 and the finished lampshade completely out of the clearance groove 302 at the bottom of the mounting platform 301, the operator can remove the finished lampshade from the placement seat 206 to complete the deburring process of the entire lampshade.
