[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0032] This invention discloses a low-cost automated transfer assembly production line for automotive lights.

[0033] Reference Figures 1 to 9A low-cost automated transfer and assembly production line for automotive lights includes workstations and a conveyor device 1. Multiple workstations are arranged along the X-axis and connected as a whole by equipment connecting plates 6. The conveyor device 1 is arranged along the X-axis, and its movable end is connected to a tooling fixture 3, suitable for conveying the tooling fixture 3 to each workstation. The tooling fixture 3 is suitable for placing products. During operation, the tooling fixture 3 is used to place and support the products, and then the conveyor device 1 transports the tooling fixture 3 to each workstation, where the products are processed. This achieves fully automated production, reduces handling difficulty, and improves production efficiency.

[0034] The conveying device 1 includes a conveyor frame 11, a rotating component 12, sprockets 13, and a drive chain 14. The rotating component 12 is fixedly connected to the conveyor frame 11. Two sets of sprockets 13 are provided along their axial direction, with at least two sprockets in each set along the length of the conveyor frame 11. One sprocket 13 is fixedly connected to the movable end of the rotating component 12, and the two sprockets 13 located at the same end along the length of the conveyor frame 11 are coaxially fixed together by a rotating shaft. Two drive chains 14 are also provided, each fitted onto the same set of sprockets 13 and driven by the sprockets 13. Multiple sets of locking plates 15 are fixedly connected to the conveyor chain, each set of locking plates 15 being suitable for connection to a tooling fixture 3. The number of sets of locking plates 15 located above the conveyor chain is equal to and corresponds one-to-one with the number of workstations, meaning that a tooling fixture 3 is present at each workstation during operation, allowing for simultaneous production and improving production efficiency. The rotating component 12 can be a high-power motor.

[0035] To facilitate transportation and disassembly of the conveyor frame 11, the conveyor frame 11 includes several fixed plates 111, which are connected by connecting plates 112. The plates are then assembled after transportation, significantly reducing transportation costs. The conveyor frame 11 is also equipped with a sprocket tension adjustment mechanism 16, which facilitates the adjustment of the position of the sprocket 13, thereby tensioning the transmission chain 14.

[0036] The tooling fixture 3 includes support members 31, vision calibration blocks 32, and sensing blocks 33. The support members 31 are suitable for supporting the product, the vision calibration blocks 32 are suitable for providing a calibration reference for vision, and the sensing blocks 33 facilitate the sensing of features. Each tooling fixture 3 has multiple support members 31 to support larger products. The number of support members 31 is equal to the number of locking plates 15 in each group, and they correspond one-to-one with the locking plates 15 in the same group.

[0037] In this embodiment, there are seven workstations that can perform different operations on the product, including a material loading workstation, a vision inspection workstation 4, a locking workstation, an assembly card receiving workstation, and a dust removal and unloading workstation 5. The vision inspection workstation 4 and the dust removal and unloading workstation 5 are described in detail here.

[0038] The visual inspection station 4 includes a first frame 41, on which are mounted a camera 42, a label printer 43, a barcode scanner 44, an industrial display 45, an industrial control box 46, and an industrial all-in-one machine 47. The industrial all-in-one machine 47 is interconnected with the label printer 43 and the barcode scanner 44 to form a traceability module. After the product is transferred to the position on the conveyor 1, the operator operates the industrial all-in-one machine 47 to trigger the label printer 43 to generate a traceability code. The operator then affixes the traceability code to a fixed position on the product and scans it to load it into the system. Next, the LED light board pre-installed on the product is scanned by the barcode scanner 44 to complete the traceability code binding. The camera 42, the industrial display 45, and the industrial control box 46 together form an LED light board detection module, and the detection results are displayed on the industrial display 45. A lighting box 48 is also connected to the first frame 41. The lighting box 48 provides the necessary power and drive for the lighting products to light up. The operator connects the lighting harness and manually lights up the product to check the lighting status.

[0039] The first frame 41 is also connected to a manual dust removal gun and an air distribution manifold 49. The manual dust removal gun is suitable for dust removal. The air distribution manifold 49 is connected to a bus air source to provide air power for the manual dust removal gun.

[0040] The workstation includes a dust removal and unloading workstation 5, which includes a second frame 51. A protective frame 52 and a dust removal assembly are connected to the second frame 51. The protective frame 52 is suitable for protecting the backflow of the workpiece 3 at the sprocket 13 of the conveyor 1. The dust removal assembly is suitable for removing dust from the product. The dust removal assembly includes an industrial vacuum cleaner 53, and a filter screen is provided at the suction port of the industrial vacuum cleaner 53.

[0041] The dust removal and unloading station 5 also includes a reflective photoelectric sensor 54 and a through-beam photoelectric sensor 55, both of which are mounted on the second frame 51. The reflective photoelectric sensor 54 is electrically connected to the rotating component 12 and is adapted to sense the sensing block 33. When the reflective photoelectric sensor 54 senses the sensing block 33, it indicates that the workpiece 3 has reached the corresponding position, at which point the rotating component 12 stops working.

[0042] The through-beam photoelectric sensor 55 is electrically connected to the rotating component 12. The through-beam photoelectric sensor 55 is suitable for sensing whether there is a product on the loading fixture 3. When the through-beam photoelectric sensor 55 detects that there is no product on the loading fixture 3, it means that the product has been removed. At this time, the rotating component 12 starts to work, realizing the cycle of the production line.

[0043] Working principle: The product is placed and supported by the loading fixture 3, and then the product is transported to each workstation by the conveying device 1. The product is then processed at the workstation, realizing fully automated production, reducing the difficulty of handling, and improving production efficiency.

[0044] With the locking plate 15 connected to the loading fixture 3, the loading fixture 3 independently supports the product, enabling synchronous transfer of the product and the fixture on the conveying device 1. By connecting various workstations through the conveying device 1, automatic transfer is integrated into the assembly process, improving production efficiency. Furthermore, the integration of product lighting, dust removal, traceability, and LED visual inspection functions into the assembly operation further enhances production efficiency.

[0045] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
