Description

Technical Field

[0001] This invention relates to the field of gasket manufacturing, specifically to a flexible line for marking and inspecting the dimensions of gaskets and a method for marking and inspecting the dimensions of gaskets. Background Technology

[0002] Currently, modern manufacturing is developing towards intelligence, precision, and efficiency. Under this trend, the requirements for precise control and quality traceability in the component production process are becoming increasingly stringent. As fundamental components in numerous mechanical devices and products, the quality and accuracy of production information for upper and lower gaskets have a crucial impact on the overall performance and quality of the product. Traditional production methods are no longer sufficient to meet the demands of high-precision, large-scale production. The emergence of flexible production lines can effectively solve this problem, achieving efficient and accurate coding and dimensional inspection of upper and lower gaskets through automation and intelligence. All industries are increasingly emphasizing product quality, and quality control has permeated the entire production process. For upper and lower gaskets, coding is a key link in achieving product quality traceability, while accurate dimensional inspection is a basic requirement for ensuring product quality. For example, in the automotive manufacturing industry, even a small gasket with an unqualified size or untraceable production information can lead to serious safety accidents. Therefore, establishing a complete flexible line for coding and dimensional inspection helps enterprises build a comprehensive quality traceability system, improving product quality and brand reputation.

[0003] In recent years, significant progress has been made in automation, machine vision, and laser technologies. These technologies have provided a solid technical foundation for the development of flexible marking and inspection lines for upper and lower gaskets. Machine vision technology enables high-precision dimensional inspection, while laser marking technology can create clear and durable marks on the gasket surface. Automation technology can seamlessly integrate marking and inspection processes, achieving a fully automated production process and improving production efficiency and stability. In today's highly competitive global manufacturing market, companies need to reduce production costs and increase production efficiency while ensuring product quality.

[0004] Therefore, it is necessary to provide a flexible line for gasket marking and inspection of dimensions, as well as a method for gasket marking and inspection of dimensions. Summary of the Invention

The marking component is used to draw QR codes on the pads, the scanning component is used to detect whether the second component can be scanned normally, the checking component is used to detect QR code deviation, and the second transfer mechanism is used to transfer pads with unqualified QR codes to the second destruction component for destruction.

[0010] Furthermore, the second transfer mechanism includes a second mounting base mounted on a second frame, a second linear module A mounted on the second mounting base, a second linear module B fixedly mounted along the Z direction at the output end of the second linear module A, a second plate mounted at the output end of the second linear module B, and several grippers fixedly mounted on the second plate.

The transfer transport mechanism is used to transfer products from the third conveyor line to the transverse transport mechanism. The transverse transport mechanism is used to transport products to the inspection mechanism for inspection. The inspection mechanism is used to perform dimensional inspection and through-hole material shortage inspection on the products. The third destructive component is used to scrap products that fail the material shortage inspection.

[0012] Furthermore, the No. 2 and No. 3 damage components have the same structure. The No. 3 damage component includes a No. 3 cylinder A fixedly mounted on the No. 3 frame, a No. 3 clamping plate A mounted on the output end of the No. 3 cylinder A, a No. 3 cylinder B mounted on the No. 3 frame, and a No. 3 clamping plate B fixedly mounted on the output end of the No. 3 cylinder B.

The size detection unit detects the size of the gasket, and the unloading unit unloads the gasket.

[0016] Beneficial effects of the invention: It can quickly perform coding and QR code detection on gaskets, effectively improving coding efficiency and accuracy.

[0017] By setting up the second and third failure components, unqualified gaskets can be scrapped, preventing unqualified gaskets from being mixed with qualified gaskets.

[0018] The modular design of the feeding unit, barcode scanning and detection unit, size detection unit and unloading unit allows for easy modular assembly according to different products and processing requirements, improving adaptability.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the first embodiment provided in this application is a flexible line for marking and inspecting the dimensions of a gasket 100. Its structure includes a fixture 1, a feeding unit 2, a barcode scanning and inspection unit 3, a dimension detection unit 4, and a unloading unit 5. The feeding unit 2 is used to provide the gasket 100, the barcode scanning and inspection unit 3 is used to laser mark the gasket 100 and detect whether the marking is qualified, the dimension detection unit 4 is used to inspect the dimensions of the gasket 100, and the unloading unit 5 is used to unload the gasket 100.

[0030] In actual use, the feeding unit 2 provides the gasket 100 to the fixture 1, and the fixture 1 is transported to the barcode scanning and inspection unit 3. The barcode scanning and inspection unit 3 draws a QR code on the gasket 100 in the fixture 1 and detects the QR code. The size detection unit 4 detects the size of the gasket 100, and the unloading unit 5 unloads the gasket 100.

[0031] In the above design, the flexible production line of this application integrates loading and unloading, coding and inspection, and dimensional detection into one unit, completing a series of processes without manual intervention. Its coding is clear, durable, and highly efficient; it can quickly and accurately measure the inner and outer diameters and thickness of the gasket 100 with an accuracy down to the micrometer level, greatly improving detection efficiency and accuracy; it has a high level of automation, with automatic loading and unloading, conveyor belt transmission, and automatic rejection of defective products, realizing fully automated production of coding and dimensional inspection of the gasket 100, reducing manpower input, and improving production efficiency and product consistency.

[0032] Specifically: such as Figure 2 As shown, the feeding unit 2 includes a first frame 21, a first hopper 22 mounted on the first frame 21, a precision positioning mechanism 23 mounted on the first frame 21, a first conveyor line 24 mounted along the X direction on the first frame 21, a first transfer mechanism 25 mounted on the first frame 21, and a flattening mechanism 26 mounted on the first frame 21 for pressing the gaskets 100 in the fixture 1 on the first conveyor line 24. Figure 3 As shown, the precision positioning mechanism 23 includes a first seat 231 mounted on a first frame 21, a plurality of first support seats 232 arranged along the Y direction on the first seat 231, and a first gripper cylinder 233 mounted on the first seat 231 corresponding one-to-one with the first support seats 232. After the pad 100 is placed on the first support seat 232, the two claws of the first gripper cylinder 233 align the pad 100.

[0033] In actual use, the first transfer mechanism 25 transfers the pad 100 in the first hopper 22 to the precision positioning mechanism 23. The two claws of the first gripper cylinder 233 are used to align the two ends of the pad 100 on the first support seat 232 to achieve precision positioning. Then, the first transfer mechanism 25 transfers the pad 100 from the first support seat 232 to the fixture 1.

[0034] In the above design, the structural design and specific implementation of the feeding unit 2 facilitate the rapid feeding of the gasket 100.

[0035] Specifically: such as Figure 2 As shown, the first transfer mechanism 25 includes a first support 251 mounted on a first frame 21, a first linear module A252 mounted on the first support 251 along the Y direction, a first linear module B253 fixedly mounted on the output end of the first linear module A252 along the Z direction, a first connecting plate 254 fixedly mounted on the output end of the first linear module B253, and a plurality of first suction cups 255 arranged along the Y direction on the first connecting plate 254. Figure 4As shown, the flattening mechanism 26 includes several pressure heads 261, a first mounting base 262 mounted on the first frame 21, a first cylinder 263 vertically mounted on the first mounting base 262, a first plate fixedly mounted on the output end of the first cylinder 263, and several elastic buffer members 264 mounted on the first plate and connected to the upper end of the pressure head 261.

[0036] In actual use, linear module B253 is driven by linear module A252 to reciprocate along the Y direction between the hopper and conveyor line 24. Linear module B253 drives connecting plate 254 to rise and fall, causing several suction cups 255 to move synchronously. When it is necessary to flatten the pad 100 in fixture 1, cylinder 263 drives plate 261 to move down, so that pressure head 261 contacts pad 100. With the continuous drive of cylinder 263, elastic buffer 264 is compressed until pressure head 261 completes the pressing of pad 100.

[0037] In the above design, the structural design and specific implementation of the No. 1 transfer mechanism 25 can effectively achieve rapid pressing of the gasket 100.

[0038] Specifically: such as Figure 5 As shown, the barcode scanning and checking unit 3 includes a second frame 31, a second conveyor line 32 disposed on the second frame 31 along the X direction and connected to the first conveyor line 24, a marking component 33, a scanning component 34, a checking component 35, a second destruction component, and a second transfer mechanism 37 disposed on the second frame 31. The marking component 33, the scanning component 34, the checking component 35, the second destruction component, and the second transfer mechanism 37 are arranged along the X direction and are all located on one side of the second conveyor line 32. The marking component 33 is used to draw a QR code on the pad 100. The scanning component 34 is used to detect whether the second QR code can be scanned normally. The checking component 35 is used to detect the code deviation of the QR code. The second transfer mechanism 37 is used to transfer the pad 100 with unqualified QR code to the second destruction component for destruction.

[0039] In actual use, after fixture 1 enters conveyor line 22 from conveyor line 1 24, the marking component 33 laser-marks the gasket 100 in fixture 1. The QR code after marking is read by the scanning component 34. If the QR code can be read normally, it is qualified; otherwise, it is unqualified. The code deviation of the QR code is checked by the code checking component 35. Gaskets 100 that fail the inspection by the scanning component 34 or the code checking component 35 are transferred to the second destruction component by the second transfer mechanism 37 for destruction. Gaskets 100 that pass both the scanning component 34 and the code checking component 35 flow into the dimension detection unit 4 along conveyor line 2 32.

[0040] In the above design, the structure of the barcode scanning and verification unit 3 facilitates the drawing of QR codes on the pad 100 and the automatic verification of the QR codes.

[0041] Specifically: such as Figure 5 As shown, the second transfer mechanism 37 includes a second mounting base 371 mounted on a second frame 31, a second linear module A372 mounted on the second mounting base 371, a second linear module B373 fixedly mounted at the output end of the second linear module A372 along the Z direction, a second plate mounted at the output end of the second linear module B373, and several grippers 374 fixedly mounted on the second plate.

[0042] In actual use, the second linear module A372 drives the second linear module B373 to move the second plate, so that the gripper 374 on the second plate transfers the defective pad 100 in the fixture 1 to the second destruction component for destruction.

[0043] Specifically: such as Figure 6 As shown, the size detection unit 4 includes a third frame 41, a third conveyor line 42 arranged along the X direction on the third frame 41, a transverse transport mechanism 43 arranged on the third frame 41, a transfer transport mechanism 44 arranged on the third frame 41, an inspection mechanism 45 arranged on the third frame 41, and a third destruction component 46 arranged on the third frame 41. The transfer transport mechanism 44 is used to transfer the products in the third conveyor line 42 to the transverse transport mechanism 43. The transverse transport mechanism 43 is used to transport the products to the inspection mechanism 45 for inspection. The inspection mechanism 45 is used to perform size detection and through-hole material shortage detection on the products. The third destruction component 46 is used to scrap products that fail the material shortage inspection.

[0044] In actual use, the fixture 1 in the second conveyor line 32 is received by the third conveyor line 42. Then, the gasket 100 in the fixture 1 is transferred to the transverse conveyor 43 by the transfer and transport mechanism 44. The transverse conveyor 43 moves the gasket 100 to the inspection position of the inspection mechanism 45 for inspection. If the inspection mechanism 45 passes the inspection, the gasket 100 is transferred back to the fixture 1 by the transfer and transport mechanism 44. If the inspection mechanism 45 fails the inspection, the gasket 100 is transferred to the third destruction component 46 by the transfer and transport mechanism 44.

[0045] In the above design, the structural design and specific implementation of the size detection unit 4 enable rapid detection of the size of the gasket 100.

[0046] Specifically: The second and third destruction components 46 have the same structure. The third destruction component 46 includes a third cylinder A fixedly mounted on the third frame 41, a third clamping plate A mounted on the output end of the third cylinder A, a third cylinder B mounted on the third frame 41, and a third clamping plate B fixedly mounted on the output end of the third cylinder B. The third clamping plate A and the third clamping plate B are arranged opposite to each other.

[0047] In actual use, the defective gasket 100 is placed between clamping plate A and clamping plate B. Then, the clamping plates A and B are driven to move in opposite directions by cylinders A and B respectively to squeeze the gasket 100, thereby destroying the gasket 100.

[0048] In the above design, the structural design and specific implementation of the second and third destruction components 46 facilitate the rapid destruction of the defective gasket 100.

[0049] Specifically: such as Figure 6 As shown, there are two of each of the transfer and handling mechanism 44, the lateral transfer and handling mechanism 43, and the out-of-stock inspection mechanism 45. The transfer and handling mechanism 44 includes a No. 3 seat A mounted on the No. 3 frame 41, a No. 3 linear module A mounted on the No. 3 seat A along the Y direction, a No. 3 linear module B mounted at the output end of the No. 3 linear module A, and several No. 3 grippers 374 mounted at the output end of the No. 3 linear module B. The lateral transfer and handling mechanism 43 includes a No. 3 seat B mounted on the No. 3 frame 41, a No. 3 linear module C mounted on the No. 3 seat B along the X direction, and a support plate fixedly mounted at the output end of the No. 3 linear module C. The inspection mechanism 45 includes a No. 3 seat C mounted on the No. 3 frame 41 and a No. 1 CCD camera and a No. 2 CCD camera mounted on the No. 3 seat C.

[0050] In actual use, the working principle of the transfer and handling mechanism 44 is as follows: the third linear module A drives the third linear module B to move along the Y direction, the third linear module B drives the third gripper 374 to rise and fall, and the third gripper 374 drives the pad 100 to rise and fall. The working principle of the transverse transfer and handling mechanism 43 is as follows: the third linear module C drives the carrier plate to move along the X direction, so that the carrier plate moves the pad 100 to below the first CCD camera and the second CCD camera. The first CCD camera detects the size of the pad 100, and the second CCD camera detects whether the pad 100 is missing material through the penetration.

[0051] In the above design, the structural design and specific implementation of the transfer and handling mechanism 44, the transverse transfer and handling mechanism 43, and the out-of-stock inspection mechanism 45 can effectively achieve rapid detection of the gasket 100.

[0052] Specifically: such as Figure 7As shown, the feeding unit 5 includes a fourth frame 51, a fourth hopper 52 mounted on the fourth frame 51, a fourth conveying mechanism 53 mounted on the fourth frame 51, and a fourth conveyor line 54 mounted on the fourth frame 51.

[0053] In actual use, the gasket 100 is transported to the fourth silo 52 by the fourth handling mechanism 53.

[0054] The method for inspecting the dimensions of gasket 100 by coding involves using the aforementioned flexible coding inspection line for gasket 100. Gasket 100 is provided to fixture 1 through feeding unit 2, and fixture 1 is transported to scanning and checking unit 3. Scanning and checking unit 3 draws a QR code on gasket 100 in fixture 1 and checks the QR code. The dimensions of gasket 100 are checked by dimension checking unit 4, and gasket 100 is unloaded by unloading unit 5.

[0055] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
