Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to an online bottom plane detector. Background Technology

[0002] A flatness checker is an instrument designed based on the principle of optical ranging. It is used to measure the flatness error of products such as flat plates, providing a basis for the flatness inspection of products. This allows manufacturers to quickly detect unqualified products during the production stage, preventing unqualified products from flowing into the next process and ensuring product yield.

[0003] Existing flatness testing equipment typically only checks the flatness of the upper surface of a product, neglecting the bottom surface. Since the flatness of the bottom surface also significantly impacts product performance, traditional testing equipment cannot meet manufacturers' production needs. Furthermore, traditional flatness inspection methods involve manual loading of materials and offline testing, resulting in low efficiency and hindering large-scale assembly line production. Utility Model Content

[0004] Therefore, it is necessary to provide an online bottom plane detector to address the shortcomings of existing technologies.

[0005] An online bottom flatness inspection instrument is connected to an assembly line for inspecting the flatness of the bottom surface of products. As the product flows into the assembly line, it is placed on a pallet. The instrument includes a frame, several support frames, a feeding line, an adjustment mechanism, a detection head, a positioning frame, and a scanning gun. The support frames, adjustment mechanism, and positioning frame are all mounted on the frame. The feeding line is mounted on the support frames. The detection head and scanning gun are respectively mounted on the adjustment mechanism and the positioning frame. The scanning gun is positioned above the feeding line, and the detection head is positioned below the feeding line. The adjustment mechanism includes a Y-axis drive device, an X-axis drive device mounted on the Y-axis drive device, and a Z-axis drive device mounted on the X-axis drive device. The detection head is mounted on the Z-axis drive device. The X-axis drive device, Y-axis drive device, and Z-axis drive device respectively drive the detection head to adjust its position on the X, Y, and Z axes, allowing the detection head to perform flatness inspection on different positions of the product's bottom.

[0006] In one embodiment, a return line is also included, which is mounted on the frame, with the feed line and return line located on the upper and lower sides inside the frame, respectively.

[0007] In one embodiment, the frame is provided with a support plate installed inside the frame, two baffles located on the front and rear sides of the frame, and an inner channel is also provided inside the frame.

[0010] In one embodiment, the tray includes an upper tray and a lower tray, wherein during feeding, the lower tray extends between the limiting strips of the two conveying components.

[0011] In one embodiment, a positioning component is also included, the positioning component including a front windshield component, a rear windshield component, and a side push component, the side push component being disposed between the rear windshield component and the front windshield component.

[0012] In one embodiment, the front and rear baffle assemblies have the same structure. The front baffle assembly includes a baffle fixing frame, a baffle cylinder mounted on the baffle fixing frame, and a baffle block connected to the baffle cylinder. The baffle fixing frame is mounted on the support plate of the feeding line. The baffle cylinder drives the baffle block to adjust its position back and forth, so that the baffle block extends into the belt to limit the pallet or exits from the belt to allow the pallet to continue to be delivered forward.

[0013] In one embodiment, the side push assembly includes a side push fixing frame, a side push cylinder mounted on the side push fixing frame, and a side push block connected to the side push cylinder. The side push fixing frame is mounted on the bearing plate of the feeding line. The side push cylinder drives the side push block to adjust back and forth. When the side push cylinder drives the side push block to adjust forward, the side push block extends above the belt and pushes the tray to a position that fits against the inner side of the limit strip.

[0014] In one embodiment, the detection head is a laser sensor.

[0015] The advantages of this online bottom flatness inspection instrument are as follows: by setting up a feeding line, an adjusting mechanism, a detection head, and a scanning gun, with the scanning gun positioned above the feeding line and the detection head positioned below the feeding line, the online bottom flatness inspection instrument can perform flatness inspection on the bottom surface of the product.

[0029] Please see Figures 1 to 7 This utility model provides an online bottom flatness tester 100, which is connected to the production line 200 and used to test the flatness of the bottom surface of the product 300. When the product 300 flows in from the production line 200, the product 300 is placed on the tray 400. The online bottom flatness tester 100, the production line 200 and the tray 400 constitute a testing system.

[0030] The tray 400 includes an upper tray 420 and a lower tray 410. The lower tray 410 is generally square in shape and has a positioning pin 412. The upper tray 420 is placed on the lower tray 410 from above, and the positioning pin 412 of the lower tray 410 is engaged with the upper tray 420. The upper tray 420 has a limiting groove 421, and the bottom of the limiting groove 421 is further provided with a first light-transmitting hole 422. The lower tray 410 has a second light-transmitting hole 412. The second light-transmitting hole 412 and the first light-transmitting hole 422 are aligned with each other in the vertical direction. When the product 300 is placed on the tray 400, the product 300 is engaged with the limiting groove 421, and the bottom edge of the product 300 is engaged with the bottom of the limiting groove 421. The bottom plane detector 100 inspects the bottom surface of the product 300 through the second light-transmitting hole 412 and the first light-transmitting hole 422.

[0031] The online bottom plane detector 100 includes a frame 10, several support frames 20, a feed line 30, a return line 40, an adjustment mechanism 50, a detection head 60, a positioning frame 70, and a scanning gun 80. The support frames 20, return lines 40, adjustment mechanisms 50, and positioning frames 70 are all mounted on the frame 10. The feed line 30 is mounted on the support frames 20. The detection head 60 and scanning gun 80 are respectively mounted on the adjustment mechanism 50 and the positioning frame 70. The feed line 30 and return line 40 are located at the upper and lower sides inside the frame 10, respectively. The scanning gun 80 is located above the feed line 30, and the detection head 60 is located below the feed line 30. In this embodiment, each lower tray 410 has two upper trays 420. Two products 300 to be inspected are placed on the two upper trays 420 and flow into the online bottom plane detector 100. The number of scanning guns 80 is also two.

[0032] The frame 10 is provided with a support plate 12 installed inside the frame 10 and two baffles 13 located on the front and rear sides of the frame 10. The frame 10 is also provided with an inner channel. The support plate 12 is located in the inner channel and divides the inner channel into an upper space 13 and a lower space 14. The return line 40 is located in the lower space 14. The support frame 20, the feed line 30, the adjustment mechanism 50, the detection head 60, the positioning frame 70 and the scanning gun 80 are located in the upper space 13. The two baffles 13 respectively block the inner channel from the front and rear sides. The baffles 13 are provided with a first through hole 111 and a second through hole 112 aligned with the feed line 30 and the return line 40, respectively. The feeding line 30 is located between two external production lines 200, and the return line 40 is located between two other external production lines 200. The feeding directions of the feeding line 30 and the return line 40 are reversed. The product 300 to be inspected flows into the machine frame 10 from the first through hole 111 of the baffle 13 along the feeding directions of the production line 200 and the feeding line 30. The adjustment device drives the inspection head 60 to inspect the product 300. After the inspection is completed, the product 300 flows out from the first through hole 111 of the other baffle 13 along the feeding direction of the feeding line 30. The return line 40 is used to return the unqualified product 300 to the rework station.

[0033] The support frame 20 is arranged in a "door" shape, and the support frames 20 are aligned with each other along the feeding direction. The feeding line 30 consists of two sets of conveying components 31, which are arranged opposite to each other. Each conveying component 31 includes a bearing plate 32 installed on the top of the support frame 20, several rollers 35 installed on the inner side of the bearing plate 32 by fasteners, a drive motor 33 installed on the bearing plate 32, a drive wheel 34 installed on the drive motor 33, a belt 36 sleeved between the rollers 35 and on the drive wheel 34, and a limiting strip 37 installed on the top of the bearing plate 32. During feeding, the product 300 to be inspected is placed on the tray 400. After the tray 400 flows into the feeding line 30, the bottom sides of the lower tray 410 abut against the belts 36 of the two conveying components 31. The drive motors 33 of the two conveying components 31 drive the belts 36 to rotate and feed the product. The lower tray 410 extends out from between the limiting strips 37 of the two conveying components 31.

[0034] The adjustment mechanism 50 includes a Y-axis drive device 51, an X-axis drive device 52 mounted on the Y-axis drive device 51, and a Z-axis drive device 53 mounted on the X-axis drive device 52. The detection head 60 is mounted on the Z-axis drive device 53. The X-axis drive device 52, Y-axis drive device 51, and Z-axis drive device 53 respectively drive the detection head 60 to adjust its position on the X, Y, and Z axes (i.e., the left-right direction, the front-back direction, and the vertical direction of the horizontal plane), so that the detection head 60 can perform planar detection on different positions of the bottom of the product 300. In this embodiment, the detection head 60 is a laser sensor. During the horizontal displacement process of the laser sensor driven by the adjustment mechanism 50, the distance information between the laser sensor and different positions of the bottom of the product 300 is obtained, thereby determining the flatness information of the bottom surface of the product 300.

[0035] This utility model also includes a positioning component (not shown in the figure), which includes a front guard component 91, a rear guard component 92, and a side push component 93. The rear guard component 92 is located near the first through hole 111 where the product 300 flows in, the front guard component 91 is located near another first through hole 111 where the product 300 flows out, and the side push component 93 is located between the rear guard component 92 and the front guard component 91.

[0036] The front baffle assembly 91 and the rear baffle assembly 92 have the same structure. The front baffle assembly 91 includes a baffle fixing frame 911, a baffle cylinder 912 mounted on the baffle fixing frame 911, and a baffle block 913 connected to the baffle cylinder 912. The baffle fixing frame 911 is mounted on the support plate 32 of the feed line 30. The baffle cylinder 912 drives the baffle block 913 to adjust its position back and forth, so that the baffle block 913 extends into the belt 36 to limit the pallet 400 or exits from the belt 36 to allow the pallet 400 to continue to be delivered forward.

[0037] The side push assembly 93 includes a side push fixing frame 931, a side push cylinder 932 mounted on the side push fixing frame 931, and a side push block 933 connected to the side push cylinder 932. The side push fixing frame 931 is mounted on the bearing plate 32 of the feed line 30. The side push cylinder 932 drives the side push block 933 to adjust back and forth. When the side push cylinder 932 drives the side push block 933 to adjust forward, the side push block 933 extends above the belt 36 and pushes the tray 400 to a position that fits against the inner side of the other side limit strip 37.

[0038] During testing, when a tray 400 flows completely from the external assembly line 200 into the online bottom plane detector 100 and is detected by the sensor, the stop block 913 of the front baffle assembly 91 and the stop block 921 of the rear baffle assembly 92 push forward respectively. The stop block 921 of the rear baffle assembly 92 prevents the tray 400 from flowing into the online bottom plane detector 100, while the stop block 913 of the front baffle assembly 91 limits the flow of the tray 400 into the online bottom plane detector 100. When the tray 400 moves to fit against the stop block 913 of the front baffle assembly 91, the sensor detects the position of the tray 400. The side push block 933 pushes the tray 400 to a position where it fits against the inner side of another support plate 32, thereby allowing the tray 400 to enter the set position. The barcode scanner 80 scans the QR code or 3D code information on the product 300 to facilitate recording of the product 300. The product 300 information is stored in correspondence with the test results for easy traceability. The adjustment mechanism 50 drives the detection head 60 to move, and the detection head 60 detects the flatness of the bottom of the product 300. After the detection is completed, the stop block 913 of the front windshield assembly 91, the stop block 921 of the rear windshield assembly 92, and the side push block 933 of the side push assembly 93 retract from above the belt 36.

[0039] The beneficial effects of this online bottom surface flatness inspection instrument 100 are as follows: By setting up a feeding line 30, an adjusting mechanism 50, a detection head 60, and a scanning gun 80, with the scanning gun 80 positioned above the feeding line 30 and the detection head 60 positioned below the feeding line 30, the online bottom surface flatness inspection instrument 100 can perform flatness inspection on the bottom surface of the product 300. Furthermore, the feeding line 30 of the online bottom surface flatness inspection instrument 100 can cooperate with an external production line 200 to achieve large-scale assembly line production, effectively improving production efficiency.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
