Description

Technical Field

[0001] The invention relates to the technical field of aluminum-plastic plate detection, in particular to a flatness detection device for aluminum-plastic plates. Background Art

[0002] As a new type of decorative material, aluminum-plastic panels have quickly gained popularity due to their economy, variety of optional colors, convenient construction methods, excellent processing performance, excellent fire resistance and noble quality. The flatness of aluminum-plastic panels is very important. Therefore, when producing and processing aluminum-plastic panels, it is usually necessary to provide flatness detection for the aluminum-plastic panels after they come off the production line.

[0003] According to the Chinese patent disclosed by application publication number: CN118482632A, a flatness detection device for aluminum-plastic panels is disclosed. After adjusting the spacing between the detection frame and the spacing adjustment frame according to the width of the aluminum-plastic panel, the aluminum-plastic panel is clamped by a clamping component and guided along a first direction. Whenever the aluminum-plastic panel moves a certain distance, the guiding component guides the flatness detection component along a second direction. During the movement of the flatness detection component along the second direction, the probe is in continuous contact with the surface of the aluminum-plastic panel to realize the flatness detection operation at different positions on both sides of the aluminum-plastic panel. Through the physical contact detection method, the disadvantages of traditional optical flatness detection are solved, which not only reduces the cost but also solves the limitations of traditional optical detection. However, the plane detection component of the flatness detection device can only move linearly, which is more suitable for square aluminum-plastic panels, but it is inconvenient to detect round aluminum-plastic panels, resulting in a relatively limited overall use range of the flatness detection device for aluminum-plastic panels.

[0039] Tension springs 2012 are sleeved on the periphery of the polished rod 206, and one end of the polished rod 206 away from the center turntable 205 is screwed with a limit nut 2013 through a thread, and the tension spring 2012 is fixedly installed between the sliding sleeve 207 and the limit nut 213. A servo motor 2011 is fixedly installed at the bottom of the round table 201, and the output shaft of the servo motor 2011 movably passes through the round table 201 and is fixedly connected to the bottom of the center turntable 205;

[0040] A shock absorbing component is provided on the top of the frame 1, and the shock absorbing component is used for shock absorbing of the detection component. The shock absorbing component includes an oil stop plate 301 fixedly installed inside the cavity block 208, and two telescopic holes 302 are provided inside the oil stop plate 301, and oil plugs 303 are slidably installed inside the two telescopic holes 302, and the outer walls of the oil plugs 303 are provided with a plurality of oil grooves 304 distributed at equal angles, and a shock absorbing spring 305 is fixedly installed between one end of the oil plug 303 close to the central turntable 205 and the inner wall of the cavity block 208 facing the oil plug 303, and the ends of the two oil plugs 303 away from the shock absorbing spring 305 are commonly connected with a shock absorbing piston 306, and the shock absorbing The outer wall of the piston 306 is slidably connected to the inner wall of the cavity block 208. A connecting seat 307 is fixedly installed on the side of the damping piston 306 away from the oil plug 303. A twisting hole 308 is penetrated through the top of the connecting seat 307. A stud 309 is rotatably installed inside the twisting hole 308. A screw cap 3009 is fixedly installed on the top of the stud 309. A lifting block 3010 is threadedly connected to the outer wall of the stud 309. A pin 3012 is fixedly installed on the end of the bottom of the lifting block 3010 away from the stud 309. A guide wheel 3013 is rotatably installed on the outer wall of the pin 3012. The outer wall of the guide wheel 3013 abuts against the inner wall of one of the guide rings 203.

[0041] Specifically, the output shaft of the servo motor 2011 drives the center turntable 205 to rotate, and the rotation of the center turntable 205 drives the two light rods 206 to rotate together. The rotation of the two light rods 206 drives the cavity block 208, the support column 209, and the scanner 2010 to rotate through the two sliding sleeves 207. During the rotation of the scanner 2010, the bottom surface of the circular aluminum-plastic plate is detected and scanned synchronously. At the same time, the cavity block 208 also drives the guide wheel 3013 in the shock-absorbing component to roll along the inner wall of the guide ring 203. When the guide wheel 3013 rolls along the guide ring 203 to the position of the release groove 204, the elastic force of the two tension springs 2012 originally in the stretched state passes through the two sliding sleeves 207, the cavity block 20 8 Pull the guide wheel 3013 along the inner wall of the release groove 204 to move to the inside of a guide ring 203 located on the periphery thereof, and abut against the inner wall of the guide ring 203. At the same time, the cavity block 208 drives the scanner 2010 to move together through the support column 209, so that the radius of the scanner 2010 rotating along with the center turntable 205 increases accordingly, and each time the center turntable 205 rotates one circle, the guide wheel 3013 enters from the release groove 204 opened on the previous guide ring 203 to the inside of a guide ring 203 of the outer layer under the action of the rebound force of the tension spring 2012, so that the radius of the scanner 2010 rotating around the center turntable 205 gradually increases, and the bottom surface of the circular aluminum-plastic plate is detected and scanned;

[0042] It should be noted that when the tension spring 2012 acts on the guide wheel 3013 to move from the inside of the release groove 204 to the inner wall of a guide ring 203 on the periphery, the impact force generated by the contact between the guide wheel 3013 and the guide ring 203 on the periphery is transmitted to the connecting seat 307 through the pin 3012, the lifting block 3010 and the stud 309, and is transmitted to the damping piston 306 through the connecting seat 307, so that the damping piston 306 moves toward the direction of the oil stop plate 301, compressing the damping piston 306 and the oil stop plate 301. 1, and the movement of the damping piston 306 will also drive the two oil plugs 303 to move together, compressing the two damping springs 305, and the movement of the damping piston 306 will inject the oil between the damping piston 306 and the oil stop plate 301 through the gap between the oil groove 304 and the telescopic hole 302 into the cavity block 208 on the other side of the oil stop plate 301, and the size of the oil groove 304 is limited, so the oil will not flow quickly to the other side of the oil stop plate 301 in a very short time, that is, the damping The piston 306 does not move quickly, thereby providing a cushioning effect to the scanner 2010 through the cavity block 208 and the support column 209, thereby preventing the impact force generated when the guide wheel 3013 contacts the inner wall of the guide ring 203 from being transmitted to the scanner 2010 and causing damage to the scanner 2010. When the impact force of the contact between the guide wheel 3013 and the inner wall of the guide ring 203 ends, the rebound force of the two cushioning springs 305 pushes the two oil plugs 303 together with the cushioning piston 306 to move back, compressing the oil stop plate 3013 to the oil stop plate 3013. 01 The oil on the other side is again drawn back between the damping piston 306 and the oil stop plate 301 through the gap between the multiple oil grooves 304 and the telescopic hole 302, and the oil will not flow back quickly in a short time, that is to say, the speed at which the damping piston 306 moves back is affected by the speed at which the oil flows back, and will not move quickly. Therefore, in the process of resetting the damping piston 306, the cavity block 208 can be prevented from vibrating, that is, the scanner 2010 can be prevented from vibrating, thereby ensuring the stability of the scanner 2010.

[0043] Embodiment 2: A driving component is provided on the top of the frame 1, and the driving component is used for longitudinal driving of the detection component;

[0044] The driving component includes a coaxial motor 401 fixedly mounted on one side of the center turntable 205.

A driven rack 403 is meshed at the bottom of the driving gear 402, and one end of the driven rack 403 is fixedly connected to a side of the cavity block 208 close to the center turntable 205.

[0045] A clearance groove 2005 is formed through one side of the central turntable 205 near the cavity block 208, and the driven rack 403 passes through the interior of the clearance groove 2005, and the width and height of the clearance groove 2005 are greater than the width and height of the driven rack 403;

[0046] A lateral moving component is provided on the top of the frame 1, and the lateral moving component is used to detect the lateral movement of the component;

[0047] The lateral moving part includes two lateral rodless cylinders 501 fixedly mounted on the bottom of the round table 201 and two lateral guide rods 502 fixedly mounted on the top of the frame 1. The two lateral rodless cylinders 501 and the two lateral guide rods 502 are distributed front and back, and the lateral rodless cylinders 501 are slidably mounted on the outer wall of the lateral guide rods 502.

[0048] Specifically, when inspecting the square aluminum-plastic plate, the screw cap 3009 is manually rotated to drive the stud 309 to rotate, so that the stud 309 generates an upward thread thrust to push the lifting block 3010 upward, and the lifting block 3010 is connected to the guide post 3015 by the sliding connection of the guide hole 3014, and can move upward more stably, and the lifting block 3010 moves upward and drives the guide wheel 3013 to move upward together through the pin shaft 3012, so that the guide wheel 3013 moves upward from the inside of the guide ring 203, and the abutment with the inner wall of the guide ring 203 is released, and the bottom of the guide wheel 3013 does not contact the top of the guide ring 203, and then the servo motor 2011 is started, and the output shaft of the servo motor 2011 drives the guide wheel 3013 to move upward. The center turntable 205 is driven to rotate, and the rotation of the center turntable 205 drives the two light rods 206 to rotate. After the light rods 206 are rotated to be perpendicular to the transverse guide rods 502, the servo motor 2011 is immediately turned off, and then the coaxial motor 401 is started. The output shaft of the coaxial motor 401 drives the driving gear 402 to rotate, and the driving gear 402 rotates to drive the driven rack 403 meshing therewith to move, and the driven rack 403 drives the cavity block 208 to move toward the center turntable 205 until the cavity block 208 moves to a position close to the center turntable 205. At the same time, the cavity block 208 also drives the two sliding sleeves 207 to slide along the two light rods 206 in the direction close to the center turntable 205, causing the two tension springs 2012 to be When the cavity block 208 moves to a position close to the center turntable 205, the coaxial motor 401 is turned off, and the rebound force of the two tension springs 2012 drives the two sliding sleeves 207 and the cavity block 208 to move away from the center turntable 205. The cavity block 208 moves through the support column 209 to drive the scanner 2010 to move together, and a linear detection is performed on the bottom of the square aluminum-plastic plate. When the cavity block 208 slides to the end of the light rod 206, the rebound force of the tension spring 2012 is completely released. At this time, the two horizontal rodless cylinders 501 are turned on, and the two horizontal rodless cylinders 501 move axially along the two horizontal guide rods 502, driving the round table 201 together with the scanner 2010 to move left or right. The distance is the size of the diameter of a scanner 2010, and then the coaxial motor 401 is started again to drive the active gear 402 to rotate, drive the driven rack 403 to move, pull the cavity block 208 to move toward the center turntable 205, and cause the two tension springs 2012 to be stretched. When the cavity block 208 moves to a position close to the center turntable 205, the coaxial motor 401 is turned off, and the resilience of the two tension springs 2012 drives the two sliding sleeves 207 and the cavity block 208 to move away from the center turntable 205. The cavity block 208 moves through the support column 209 to drive the scanner 2010 to move together, and a linear detection is performed on the bottom of the square aluminum-plastic plate. This cycle is repeated until the detection and scanning of the bottom surface of the square aluminum-plastic plate is completed.

[0049] Embodiment 3: A suction component is provided on the top of the frame 1, and the suction component is used for suction and fixation of the aluminum-plastic plate;

[0050] The adsorption component includes two longitudinal guide rods 601 fixedly installed on the top of the frame 1, the two longitudinal guide rods 601 are distributed left and right, and the two longitudinal guide rods 601 are located between the front and rear two transverse guide rods 502, the outer walls of the two longitudinal guide rods 601 are slidably installed with longitudinal rodless cylinders 602, the outer walls of the two longitudinal rodless cylinders 602 are jointly fixedly installed with a carrier 603, a negative pressure machine 604 is fixedly installed in the middle of the front of the carrier 603, a cross bracket 605 is fixedly installed at the bottom of the negative pressure machine 604, four suction cups 606 distributed vertically and horizontally are fixedly installed at the bottom of the cross bracket 605, the four suction cups 606 are located at the top of the round table 201, and the input end of the suction cup 606 and the output end of the negative pressure machine 604 are connected through an air pipe;

[0051] The present embodiment is specifically, when the aluminum-plastic plate is detected, firstly, negative pressure suction is generated to four suction cups 606 by the negative pressure machine 604, and the aluminum-plastic plate is placed at the bottom of four longitudinal guide rods 601, and the top surface of the aluminum-plastic plate is adsorbed by four suction cups 606, so that the aluminum-plastic plate is fixed and limited, and then the left and right two longitudinal rodless cylinders 602 are opened to move downward along the two longitudinal guide rods 601 on the left and right, and the two longitudinal rodless cylinders 602 move downward to jointly drive the carrier 603, the negative pressure machine 604, the cross bracket 605 and the four suction cups 606 to move downward together, and the four suction cups 606 move downward to drive the adsorbed aluminum-plastic plate to move downward together, so that the bottom surface of the aluminum-plastic plate is close to the top of the scanner 2010, until the bottom surface height of the aluminum-plastic plate reaches the detectable height of the scanner 2010, the two longitudinal rodless cylinders 602 are stopped, so as to facilitate the detection scanning of the servo motor 2011.

[0052] The flatness detection device for aluminum-plastic panels of the present invention is at work. When detecting a circular aluminum-plastic panel, firstly, a negative pressure suction force is generated on four suction cups 606 by a negative pressure machine 604, and the circular aluminum-plastic panel is placed on the bottom of four longitudinal guide rods 601. The top surface of the circular aluminum-plastic panel is adsorbed by four suction cups 606 to fix the aluminum-plastic panel. Then, the left and right longitudinal rodless cylinders 602 are opened to move the panel downward along the left and right longitudinal guide rods 601. The two longitudinal rodless cylinders 602 move downward to jointly drive the carrier 603, the negative pressure machine 604, the cross bracket 605 and the four suction cups 606 to move downward together. The four suction cups 606 move downward to drive the adsorbed circular aluminum-plastic panel to move downward together, so that the bottom surface of the circular aluminum-plastic panel approaches the top of the scanner 2010. After the bottom surface height of the circular aluminum-plastic panel reaches the detectable height of the scanner 2010, the two longitudinal rodless cylinders 602 are stopped.

[0053] Subsequently, the servo motor 2011 is started, and the output shaft of the servo motor 2011 drives the central turntable 205 to rotate. The rotation of the central turntable 205 drives the two light rods 206 to rotate together. The rotation of the two light rods 206 drives the cavity block 208, the support column 209, and the scanner 2010 to rotate through the two sliding sleeves 207. During the rotation of the scanner 2010, the bottom surface of the circular aluminum-plastic plate is detected and scanned synchronously. At the same time, the cavity block 208 also drives the guide wheel 3013 in the shock-absorbing component to roll along the inner wall of the guide ring 203. When the guide wheel 3013 rolls along the guide ring 203 to the position of the release groove 204, the elastic force of the two tension springs 2012 that were originally in a stretched state passes through the two sliding sleeves 207, the cavity block 208, the support column 209, and the scanner 2010. The block 208 pulls the guide wheel 3013 to move along the inner wall of the release groove 204 to the inside of a guide ring 203 located on the periphery thereof, and abuts against the inner wall of the guide ring 203. At the same time, the cavity block 208 drives the scanner 2010 to move together through the support column 209, so that the radius of the scanner 2010 rotating along with the center turntable 205 increases accordingly, and each time the center turntable 205 rotates one circle, the guide wheel 3013 enters from the release groove 204 opened on the previous guide ring 203 to the inside of a guide ring 203 of the outer layer under the action of the rebound force of the tension spring 2012, so that the radius of the scanner 2010 rotating around the center turntable 205 gradually increases, and the bottom surface of the circular aluminum-plastic plate is detected and scanned;

[0054] When the tension spring 2012 acts on the guide wheel 3013 to move from the inside of the release groove 204 to the inner wall of a guide ring 203 on the periphery, the impact force generated by the contact between the guide wheel 3013 and a guide ring 203 on the periphery is transmitted to the connecting seat 307 through the pin 3012, the lifting block 3010 and the stud 309, and is transmitted to the damping piston 306 through the connecting seat 307, so that the damping piston 306 moves toward the direction of the oil stop plate 301, compressing the oil between the damping piston 306 and the oil stop plate 301. The movement of the damping piston 306 will also drive the two oil plugs 303 to move together, compressing the two damping springs 305, and the movement of the damping piston 306 will inject the oil between the damping piston 306 and the oil stop plate 301 into the cavity block 208 on the other side of the oil stop plate 301 through the gap between the oil groove 304 and the telescopic hole 302, and the size of the oil groove 304 is limited, so the oil will not flow into the other side of the oil stop plate 301 quickly in a very short time, that is, the damping piston 30 6 does not move quickly, thereby providing a shock-absorbing effect to the scanner 2010 through the cavity block 208 and the support column 209, preventing the impact force generated when the guide wheel 3013 contacts the inner wall of the guide ring 203 from being transmitted to the scanner 2010, thereby causing damage to the scanner 2010. When the impact force of the contact between the guide wheel 3013 and the inner wall of the guide ring 203 ends, the rebound force of the two shock-absorbing springs 305 pushes the two oil plugs 303 together with the shock-absorbing piston 306 to move back, and compresses the oil stop plate 301 The oil on the other side is drawn back to between the damping piston 306 and the oil stop plate 301 through the gap between the plurality of oil grooves 304 and the telescopic hole 302, and the oil will not flow back quickly in a short time, that is, the speed of the damping piston 306 moving back is affected by the speed of the oil flowing back, and will not move quickly, so that during the process of the damping piston 306 resetting, the cavity block 208 can be prevented from vibrating, that is, the scanner 2010 can be prevented from vibrating, thereby ensuring the stability of the scanner 2010;

[0055] When it is necessary to detect the square aluminum-plastic plate, the negative pressure suction force generated by the negative pressure machine 604 is also used to act on the four suction cups 606, and the top of the square aluminum-plastic plate is adsorbed, and then the left and right two longitudinal rodless cylinders 602 are opened to move downward along the two longitudinal guide rods 601 on the left and right. The two longitudinal rodless cylinders 602 move downward to jointly drive the carrier 603, the negative pressure machine 604, the cross bracket 605 and the four suction cups 606 to move downward together, and the four suction cups 606 move downward to drive the adsorbed circular aluminum-plastic plate to move downward together, so that the bottom surface of the circular aluminum-plastic plate is close to the top of the scanner 2010, until the bottom surface height of the circular aluminum-plastic plate reaches the detectable height of the scanner 2010, and then the two longitudinal rodless cylinders 602 are stopped;

[0056] Subsequently, the screw cap 3009 is manually rotated to drive the stud 309 to rotate, so that the stud 309 generates an upward threaded thrust, pushing the lifting block 3010 upward, and the lifting block 3010 can move upward more stably through the sliding connection between the guide hole 3014 and the guide column 3015, and the lifting block 3010 moves upward through the pin shaft 3012 to drive the guide wheel 3013 to move upward together, so that the guide wheel 3013 moves upward from the inside of the guide ring 203, releasing the abutment with the inner wall of the guide ring 203, and the bottom of the guide wheel 3013 will not contact the top of the guide ring 203, and then the servo motor 2011 is started, and the central turntable 205 is driven to rotate by the output shaft of the servo motor 2011. The rotation of the center turntable 205 drives the two polished rods 206 to rotate. After the polished rods 206 are rotated to be perpendicular to the transverse guide rods 502, the servo motor 2011 is immediately turned off, and then the coaxial motor 401 is started. The output shaft of the coaxial motor 401 drives the driving gear 402 to rotate. The driving gear 402 rotates to drive the driven rack 403 meshing therewith to move. The driven rack 403 drives the cavity block 208 to move toward the center turntable 205 until the cavity block 208 moves to a position close to the center turntable 205. At the same time, the cavity block 208 also drives the two sliding sleeves 207 to slide along the two polished rods 206 in the direction close to the center turntable 205, causing the two tension springs 2012 to be stretched. When the cavity block 2 After the scanner 2010 moves to a position close to the center turntable 205, the coaxial motor 401 is turned off, and the rebound force of the two tension springs 2012 drives the two sliding sleeves 207 and the cavity block 208 to move away from the center turntable 205. The cavity block 208 moves through the support column 209 to drive the scanner 2010 to move together, and a linear detection is performed on the bottom of the square aluminum-plastic plate. When the cavity block 208 slides to the end of the light rod 206, the rebound force of the tension spring 2012 is completely released. At this time, the two horizontal rodless cylinders 501 are turned on, and the two horizontal rodless cylinders 501 move axially along the two horizontal guide rods 502, driving the round table 201 to move together with the scanner 2010, so that the scanner 2010 moves one scanning angle to the left or right. The distance of the diameter of the instrument 2010 is then started again, and the coaxial motor 401 is started to drive the driving gear 402 to rotate, driving the driven rack 403 to move, pulling the cavity block 208 to move toward the center turntable 205, causing the two tension springs 2012 to be stretched. When the cavity block 208 moves to a position close to the center turntable 205, the coaxial motor 401 is turned off, and the resilience of the two tension springs 2012 drives the two sliding sleeves 207 and the cavity block 208 to move away from the center turntable 205. The cavity block 208 moves through the support column 209 to drive the scanner 2010 to move together, and a linear detection is performed on the bottom of the square aluminum-plastic plate. This cycle is repeated until the detection and scanning of the bottom surface of the square aluminum-plastic plate is completed.
