Description

An automated production line for 3D line scanning inspection of flatness and a method for flatness inspection. Technical Field

[0001] This invention relates to the field of flatness testing equipment technology, specifically to an automated production line and method for 3D line scanning flatness testing. Background Technology

[0002] 3D line scanning for flatness inspection is a high-precision method. It scans the surface of an object to obtain its three-dimensional coordinates, thereby calculating the flatness of the surface. This method offers advantages such as high precision, high efficiency, and non-contact operation, significantly improving production efficiency and product quality.

[0003] Existing 3D line scanning inspection generally requires inspection from multiple angles when performing flatness inspection on an object. However, relying on a single inspection device to inspect an object can easily lead to data deviations and affect inspection efficiency. Setting up multiple inspection devices to inspect multiple surfaces is relatively expensive. Furthermore, when objects with unqualified flatness are detected, if they are not sorted and removed in time, they can easily be mixed with a batch of qualified products, and the re-sorting by staff will significantly reduce work efficiency.

[0004] To address this, an automated production line for 3D line scanning inspection of flatness and a method for flatness inspection are proposed. Summary of the Invention

A telescopic plate is provided at the end of the connecting pipe away from the piston cylinder. The telescopic plate is slidably connected to the L-shaped plate.

[0010] As a preferred technical solution of the 3D line scan detection flatness automatic production line of the present invention, multiple sets of pulleys are provided on the upper end of the inner wall of the two sets of support frames, and a conveyor belt is rotatably connected to the surface of the pulleys. A detection device is installed on the surface of the support frame.

[0011] As a preferred technical solution of the 3D line scan detection flatness automatic production line of the present invention, the protrusions are linearly distributed on the top of the support plate, and the spacing between the protrusions matches the size of the flat object to be detected. The height of the support plate is lower than the height of the conveyor belt.

[0017] A method for flatness detection in an automated production line using D-line scanning, characterized by the following steps:

[0018] Step 1: By placing the flat object to be inspected on the conveyor block, the first motor is started to intermittently transport the flat object to be inspected onto the conveyor belt for transport, while waiting for inspection;

[0019] Step 2: When the flat object to be tested is moved above the support disk, the second motor is started to raise the support disk, which in turn drives the object to be tested to rotate and perform a full-range flatness test.

[0020] Step 3: When the flatness of the detected item is not up to standard, the item is removed by the sorting component.

[0021] In summary, the present invention has the following main beneficial effects:

[0022] 1. By starting the second motor, the threaded screw drives the threaded sleeve to rise, which in turn drives the support disc to rotate the object being tested. This invention effectively enables the testing device to perform all-round flatness testing on the object being tested, thereby improving the accuracy of flatness testing.

[0023] 2. By starting the first motor, the first and second rotating rods drive the conveyor plate to move in a circular motion, which in turn causes the conveyor block to move the object to be detected. This allows the object to be detected to be gradually transported from between the protrusions onto the conveyor belt, effectively achieving intermittent transport of the object to be detected and avoiding the inability to properly detect the flatness of the object if the distance between the objects is too close.

[0024] 3. In this invention, when the movable rod rises to a certain position in the moving slot, it drives the piston rod to rise synchronously. The piston rod drives the piston to compress the gas inside the piston cylinder, so that the gas enters the L-shaped plate through the connecting pipe. The air pressure pushes the telescopic plate out, pushing out objects with unqualified flatness from the support disc. This effectively distinguishes between qualified and unqualified objects, avoiding the need for manual sorting and further improving work efficiency. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of the present invention will now be described.

[0039] An automated production line for 3D line scanning to detect flatness, as shown in Figures 1-8, includes an overall component 100. The overall component 100 includes two sets of support frames 110. A conveying component 200 is provided on one side between the two sets of support frames 110, and a rotating component 300 is provided between the support frames 110. A sorting component 400 is fixedly connected to the rotating component 300.

[0040] The conveying assembly 200 includes two sets of support plates 210. A first motor 220 is fixedly connected to one side of the front end of the support plate 210, and several sets of protrusions 221 are fixedly connected to the top of the support plate 210. A base rod 230 is fixedly connected to the output end of the first motor 220. A first rotating rod 240 is fixedly connected to the end of the base rod 230 away from the first motor 220. A belt 250 is rotatably connected to the surface of the first rotating rod 240. A second rotating rod 260 is rotatably connected to the inner wall of the belt 250 away from the first rotating rod 240. A conveying plate 270 is fixedly connected to the front end of the second rotating rod 260, and several sets of conveying blocks 271 are fixedly connected to the top of the conveying plate 270.

[0041] The rotating assembly 300 includes a second motor 310, the output end of which is fixedly connected to a rotating disk 320. A threaded screw 330 is fixedly connected to the top of the rotating disk 320, and a fixed disk 340 is provided directly above the rotating disk 320. A threaded sleeve 360 ​​is rotatably connected to the surface of the threaded screw 330. A connecting rod 380 is provided at the top of the fixed disk 340, and a square block 370 is welded to the top of the connecting rod 380. The square block 370 is slidably connected to the threaded sleeve 360, and a supporting disc 390 is fixedly connected to the top of the threaded sleeve 360.

[0042] The sorting assembly 400 includes a horizontal plate 410 fixedly connected to the surface of the threaded sleeve 360. An L-shaped plate 420 is welded to the top of the horizontal plate 410 away from the threaded sleeve 360. Two sets of piston cylinders 440 are slidably connected inside the horizontal plate 410. A piston 450 is slidably connected inside the two sets of piston cylinders 440. A piston rod 460 is fixedly connected to the top of the piston 450. A moving groove 461 is opened in the piston rod 460. A movable rod 470 is slidably connected in the moving groove 461. A connecting plate 480 is fixedly connected to the top of the movable rod 470. A round shaft 490 is fixedly connected to the top of the connecting plate 480 away from the movable rod 470. A connecting pipe 4910 is connected to the upper surface of the piston cylinder 440. A telescopic plate 4920 is provided at the end of the connecting pipe 4910 away from the piston cylinder 440. The telescopic plate 4920 is slidably connected to the L-shaped plate 420.

[0043] By placing the object to be inspected for flatness on the conveyor block 271, the first motor 220 is started. The first motor 220 drives the first rotating rod 240 and the belt 250 to rotate. The belt 250 drives the second rotating rod 260 to rotate. The first rotating rod 240 and the second rotating rod 260 drive the conveyor plate 270 to move in a circular motion, causing the conveyor block 271 to move the object to be inspected. The object is gradually conveyed from between the protrusions 211 onto the conveyor belt 130, which effectively achieves intermittent conveying of the object to be inspected, avoiding the problem of the object being too close to the surface and thus failing to perform flatness inspection properly. When the object to be inspected is conveyed to the support disc 390 on the conveyor belt 130, the second motor 310 is started, driving the rotating disc 320 to rotate. The rotating disc 320 drives the threaded screw 330 to rotate, and the threaded screw 330 drives the threaded sleeve 360 ​​to rise. Through the rotation of the rotating disc 320 and the threaded sleeve 390, the object is moved. The upward movement of the 60° section causes the support disc 390 to rotate and lift the object being inspected, effectively enabling the inspection device 140 to perform omnidirectional flatness inspection of the object, thus improving the accuracy of the flatness inspection. When the flatness of the object is found to be unqualified, the second motor 310 continuously drives the threaded sleeve 360 ​​and the support disc 390 to rise. The support disc 390 pulls the movable rod 470 to rise. When the movable rod 470 rises to a certain position in the moving groove 461, it drives the piston rod 460 to rise synchronously. The piston rod 460 drives the piston 450 to compress the gas inside the piston cylinder 440, causing the gas to enter the L-shaped plate 420 through the connecting pipe 4910. The air pressure pushes the telescopic plate 4920 out, pushing the unqualified object out of the support disc 390. This effectively distinguishes between qualified and unqualified objects, avoiding the need for manual sorting and further improving work efficiency.

[0044] Please refer to Figures 1, 2, and 3. Multiple sets of pulleys 120 are provided on the upper part of the inner wall of both sets of support frames 110. A conveyor belt 130 is rotatably connected to the surface of the pulleys 120. A detection device 140 is installed on the surface of the support frame 110. Protrusions 211 are linearly arrayed on the top of the support plate 210, and the spacing between the protrusions 211 matches the size of the planar object to be detected. The height of the support plate 210 is lower than the height of the conveyor belt 130. The first rotating rod 240 and the second rotating rod 260 are both fixedly connected to the conveyor plate 270. One end of the second rotating rod 260 is rotatably connected to the support plate 210.

[0045] By intermittently conveying the object to be inspected onto the conveyor belt 130, the flatness of the inspection device 140 can be easily inspected.

[0046] Please refer to Figures 4, 5, and 6. The top of the fixed plate 340 is provided with telescopic rods 350 on both sides. The top of the telescopic rods 350 is fixedly connected to the support disc 390. The bottom of the support disc 390 is provided with a groove 391. The lower end of the threaded sleeve 360 ​​is fixedly connected with locking blocks 361 on both sides. The inner wall of the square block 370 is provided with sliding grooves 371 that match the locking blocks 361. The locking blocks 361 are slidably connected to the square block 370 through the sliding grooves 371. The fixed plate 340 is fixedly connected to the connecting rod 380. The two ends of the connecting rod 380 are fixedly connected to the inner wall of the support frame 110.

[0047] By fixing both ends of the connecting rod 380 to the inner wall of the support frame 110, the threaded screw 330 is prevented from rotating, and the threaded sleeve 360 ​​rotates synchronously.

[0048] Please refer to Figures 7 and 8. A cylinder 430 is fixedly connected to the bottom end of the piston cylinder 440, and the circular shaft 490 is slidably connected to the support disk 390 through the groove 391.

[0049] The rotating support disc 390 causes the circular shaft 490 to slide inside the groove 391, preventing the circular shaft 490 from rotating synchronously.

[0050] In use, the object to be tested for flatness is placed on the conveyor block 271, and the first motor 220 is started. The first motor 220 drives the first rotating rod 240 and the belt 250 to rotate. The belt 250 drives the second rotating rod 260 to rotate. The first rotating rod 240 and the second rotating rod 260 drive the conveyor plate 270 to move in a circular motion, causing the conveyor block 271 to move the object to be tested. The object is gradually conveyed from between the protrusions 211 onto the conveyor belt 130, which can effectively achieve intermittent conveying of the object to be tested, avoiding the problem of the object being too close to the support disc 390. When the object to be tested is conveyed to the support disc 390 on the conveyor belt 130, the second motor 310 is started, driving the rotating disc 320 to rotate. The rotating disc 320 drives the threaded screw 330 to rotate, and the threaded screw 330 drives the threaded sleeve 360 ​​to rise. Through the rotation of the rotating disc 320 and the threaded sleeve... The rising of the cylinder 360 causes the support disc 390 to rotate and lift the object being tested, effectively enabling the testing device 140 to perform omnidirectional flatness testing on the object, thus improving the accuracy of the flatness test. When the flatness of the object is found to be unqualified, the second motor 310 continuously drives the threaded sleeve 360 ​​and the support disc 390 to rise. The support disc 390 pulls the movable rod 470 to rise. When the movable rod 470 rises to a certain position in the moving groove 461, it drives the piston rod 460 to rise synchronously. The piston rod 460 drives the piston 450 to compress the gas inside the piston cylinder 440, causing the gas to enter the L-shaped plate 420 through the connecting pipe 4910. The air pressure pushes the telescopic plate 4920 out, pushing the unqualified object out of the support disc 390. This effectively distinguishes between qualified and unqualified objects, avoiding the need for manual sorting and further improving work efficiency.

[0051] An automated production line and method for flatness inspection using 3D line scanning, characterized by the following steps:

[0052] Step 1: By placing the flat object to be inspected on the conveyor block 271, the first motor 220 is started to intermittently transport the flat object to be inspected onto the conveyor belt 130 for transport, and wait for inspection;

[0053] Step 2: When the flat object to be tested is moved above the support disk 390, the second motor 310 is started to raise the support disk 390, which drives the object to be tested to rise and rotate. The flatness of the object is then tested from all directions by the detection device 140.

[0054] Step 3: When the flatness of the detected item is not up to standard by the detection device 140, the detected item is removed by the sorting component 400.
