Description

Technical Field

[0001] This utility model belongs to the field of vehicle lighting production, and particularly relates to a feeding device and vehicle lighting production equipment. Background Technology

[0002] LED (Light Emitting Diode) automotive lights, with their significant advantages such as high efficiency, energy saving, low carbon emissions, long lifespan, and flexible design, have become an indispensable key light source in the modern automotive lighting field and are widely used. A typical LED automotive light production process involves a series of closely linked critical quality control steps requiring high positional accuracy. Its core processes typically include: precisely assembling components such as LED chips, lenses, drivers, and heat dissipation structures into the lamp body; then rigorously testing the photoelectric performance (such as brightness, color temperature, voltage and current characteristics, and functionality) of the assembled LED automotive lights; simultaneously, scanning and laser marking the LED automotive lights; and finally, sorting the automotive lights into different collection channels based on the test results. In this production process, an efficient feeding device is needed to sequentially and accurately transport the carriers holding the LED automotive lights to each of the aforementioned workstations.

[0003] Currently, the method for transporting vehicles carrying LED vehicle lights to various work sites involves setting up multiple independent devices at different points on the conveyor belt to perform the work separately. These devices are arranged along the extension direction of the conveyor belt, resulting in an excessive amount of lateral space occupied by the entire feeding device. Furthermore, existing feeding devices often rely on a single position sensor to detect the displacement of the conveyor belt and indirectly infer the position status of materials at all work stations. This method cannot detect whether the materials at each specific work station are truly in place, leading to insufficient accuracy in material arrival detection. Utility Model Content

[0004] The purpose of this application is to provide a feeding device and automotive lamp production equipment, aiming to solve the problems of how to reduce the space occupied by the feeding device and how to improve the accuracy of material arrival detection.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a feeding device is provided, comprising a position detection structure, a frame, a turntable rotatably connected to the frame, a carrier disposed on the turntable for carrying materials, and a drive structure disposed on the frame and connected to the turntable. The feeding device has a plurality of working stations arranged at intervals along the circumference of the turntable. The drive structure is used to drive the turntable to rotate so that the carrier moves sequentially to each of the working stations. A plurality of position detection structures are arranged at intervals along the circumference of the turntable, and each position detection structure corresponds one-to-one with each of the working stations. Each position detection structure is used to identify the corresponding material to detect whether the material has moved to the corresponding working station.

[0007] In some embodiments, the position detection structure is disposed below the turntable, the turntable has a first through hole corresponding to the position detection structure, the carrier has a second through hole communicating with the first through hole, the material corresponds to the second through hole, and the position detection structure identifies the material through the first through hole and the second through hole.

[0008] In some embodiments, the position detection structure includes a bracket disposed below the turntable and a photoelectric sensor connected to the bracket. The photoelectric sensor is used to project a detection beam toward a preset position. When the material moves to the preset position, the detection beam passes through the first through hole and the second through hole in sequence and irradiates the material.

[0009] In some embodiments, the carrier is used to carry a plurality of the materials, a plurality of first through holes are arranged at intervals, a plurality of second through holes are arranged at intervals, and each of the materials, each of the first through holes and each of the second through holes corresponds one-to-one.

[0010] In some embodiments, the carrier includes a placement seat for carrying the material and a limiting block disposed on the placement seat. A plurality of limiting blocks are arranged at intervals along the circumference of the placement seat, and the plurality of limiting blocks surround to form a limiting space for limiting the material. The second through hole is formed in the placement seat.

[0011] In some embodiments, the shape of the limiting space is adapted to the outer contour of the material.

[0012] In some embodiments, the limiting block has an abutting surface that abuts against the material, the abutting surface being adapted to the shape of the outer surface of the material.

[0013] In some embodiments, multiple carriers are arranged at circumferential intervals along the turntable, and the drive structure drives the turntable to rotate so that each carrier moves to its respective work station.

[0014] In some embodiments, the vehicle is detachably connected to the turntable.

[0015] Secondly, an automotive lighting production equipment is provided, which includes the feeding device described above.

[0016] The beneficial effects of this application are as follows: When the feeding device of this application is in use, the drive structure drives the turntable to rotate so that the carrier moves to each working station in sequence. By arranging each working station at intervals along the circumference of the turntable, compared with the linear layout where the material transmission path is a straight line, the turntable transmission method occupies less space and has a more compact structure, which is conducive to reducing the space occupied by the feeding device. In addition, each working station is equipped with an independent position detection structure. Each position detection structure directly detects whether the material entering the corresponding working station has moved into place, avoiding the accumulation of errors caused by traditional single detection points or only detecting the displacement of the transmission belt, thereby improving the accuracy of material arrival detection.

[0027] Please see Figures 1 to 3This application provides a feeding device, including a position detection structure 40, a frame 50, a turntable 20 rotatably connected to the frame 50, a carrier 10 disposed on the turntable 20 and used to carry material 200, and a drive structure 30 disposed on the frame 50 and connected to the turntable 20. The feeding device has a plurality of working stations 300 arranged at intervals along the circumference of the turntable 20. The drive structure 30 is used to drive the turntable 20 to rotate so that the carrier 10 moves sequentially to each working station 300. A plurality of position detection structures 40 are arranged at intervals along the circumference of the turntable 20. Each position detection structure 40 corresponds one-to-one with each working station 300. Each position detection structure 40 is used to identify the corresponding material 200 to detect whether the material 200 has moved to the corresponding working station 300.

[0028] In this embodiment, material 200 is specifically one of the components of an LED vehicle light. The multiple workstations 300 can be assembly workstations, testing workstations, barcode scanning workstations, laser marking workstations, and sorting workstations, etc. The drive structure 30 drives the turntable 20 to rotate, so that the carrier 10 moves sequentially to each workstation 300. The assembly workstation precisely assembles multiple components into a lamp body. The testing workstation is used to conduct rigorous photoelectric performance testing on the assembled LED vehicle light. The barcode scanning workstation is used to read the barcode or QR code attached to the vehicle light to bind product identity or enter traceability information. The laser marking workstation uses a laser to engrave permanent marks such as serial numbers, production dates, and certification marks at specific positions on the vehicle light. The sorting workstation is used to sort the vehicle lights into different collection channels according to the test results.

[0029] Understandably, in this embodiment, the turntable 20 has a disc-shaped structure, the carrier 10 is disposed on the edge of the turntable 20, and multiple workstations 300 are arranged in a circular array around the rotation center of the turntable 20. Multiple position detection structures 40 are arranged in a circular array around the rotation center of the turntable 20.

[0030] When the feeding device of this application is in use, the drive structure 30 drives the turntable 20 to rotate so that the carrier 10 moves sequentially to each working station 300. By arranging each working station 300 at intervals along the circumference of the turntable 20, compared with the linear layout where the material 200 is transported in a straight line, the turntable 20 transmission method occupies less space and has a more compact structure, which is beneficial to reducing the space occupied by the feeding device. In addition, each working station 300 is equipped with an independent position detection structure 40. Each position detection structure 40 directly detects whether the material 200 entering the corresponding working station 300 has moved into place, avoiding the accumulation of errors caused by traditional single detection points or only detecting the displacement of the transmission belt, thereby improving the accuracy of material 200 arrival detection.

[0031] In addition, the entire system only requires one drive structure 30 to drive the conveying, which greatly simplifies the drive and control system. It does not require a complex linear conveyor belt system, multi-axis robotic arms or a large number of independent propulsion cylinders to transfer materials 200 between multiple workstations 300.

[0032] In this embodiment, when the position detection structure 40 of a certain workstation 300 fails to detect material 200 or detects that material 200 is not fully in place, the problematic workstation can be immediately and accurately identified. The system can then issue an alarm or pause signal specifically for that workstation without stopping the operation of the entire turntable 20, allowing other workstations 300 to continue operating. This improves the overall fault tolerance and operating efficiency of the equipment. It also facilitates rapid location of the fault source, significantly shortening the time required for fault diagnosis and troubleshooting.

[0033] Optionally, the drive structure 30 may include a stepper motor, a reducer, and an indexing structure. The stepper motor provides precise angle control, controlling the rotation angle and speed by receiving pulse signals. The reducer is typically a planetary reducer or a worm gear reducer, which reduces the motor's output speed while significantly increasing the output torque to meet the requirements of driving the large inertia turntable 20, and also improves system rigidity and reduces vibration. The indexing mechanism is key to achieving precise indexing and positioning. Specifically, the indexing mechanism can be a cam divider, which uses a conjugate cam structure to convert the continuous rotational motion of the motor into intermittent precise indexing motion of the turntable 2020. This results in extremely high positioning accuracy and repeatability, strong load-bearing capacity, good rigidity, smooth operation, and long service life. It is suitable for medium-to-high speed, high-precision, and heavy-load applications.

[0034] In some embodiments, the position detection structure 40 is disposed below the turntable 20. The turntable 20 has a first through hole 21 corresponding to the position detection structure 40, and the carrier 10 has a second through hole 111 communicating with the first through hole 21. The material 200 corresponds to the second through hole 111, and the position detection structure 40 identifies the material 200 through the first through hole 21 and the second through hole 111. By disposing the position detection structure 40 below the turntable 20 and identifying the material 200 through the first through hole 21 and the second through hole 111, the space below the turntable 20 can be fully utilized, allowing the position detection structure 40 to be positioned within the range determined by the rotation trajectory of the turntable 20 without occupying additional space. This further reduces the space occupied by the feeding device and achieves miniaturization.

[0035] In some embodiments, the position detection structure 40 includes a bracket 41 disposed below the turntable 20 and a photoelectric sensor 42 connected to the bracket 41. The photoelectric sensor 42 is used to project a detection beam toward a preset position. When the material 200 moves to the preset position, the detection beam passes through the first through hole 21 and the second through hole 111 in sequence and irradiates the material 200.

[0036] By incorporating photoelectric sensor 42, positioning accuracy can be improved, ensuring that material 200 is strictly aligned with high-precision stations such as barcode scanning and laser marking, thus avoiding quality issues such as marking misalignment and barcode scanning failure caused by minute offsets. Furthermore, non-contact detection is employed, preventing damage to the surface of material 200, and the photoelectric sensor 42 has an extremely fast response speed, meeting the rapid switching rhythm of the turntable 20 stations.

[0037] In some embodiments, the carrier 10 is used to carry multiple materials 200. Multiple first through holes 21 and multiple second through holes 111 are arranged at intervals, with each material 200, each first through hole 21, and each second through hole 111 corresponding to one another. Because the carrier 10 carries multiple materials 200, the rotation of the turntable 20 can drive the movement of multiple materials 200, thereby significantly improving the material conveying efficiency. Furthermore, each material 200 on the carrier 10 can be detected through its corresponding first through hole 21 and second through hole 111, thus allowing for precise control over the arrival status of each material 200.

[0038] In some embodiments, multiple carriers 10 are arranged at circumferential intervals along the turntable 20. The drive structure 30 drives the turntable 20 to rotate, so that each carrier 10 moves to a work station 300. Understandably, the multiple carriers 10 are arranged in a circular array around the rotation center of the turntable 20, and the positions of multiple position detection structures 40 correspond to the positions of the multiple carriers 10. The drive structure 30 controls the rotation of the turntable 20 so that the multiple carriers 10 sequentially correspond to each work station 300. When the turntable 20 is in a certain position, after the material 200 on the carrier 10 corresponding to the work station 300 on the turntable 20 has finished its work, the turntable 20 rotates to the next position, so that the carrier 10 on the turntable 20 corresponds to the next work station 300. Then, the work station 300 continues to work on the material 200 on its corresponding carrier 10 until all carriers 10 have finished their work sequentially. In this way, when each material 200 is being processed, the carrier 10 always keeps the material 200 fixed, eliminating the need to repeatedly pick up and put down the material 200, reducing the time consumed by repeatedly picking up and putting down the material 200, and helping to improve the working efficiency of the material 200.

[0039] In some embodiments, the carrier 10 includes a placement seat 11 for carrying material 200 and limiting blocks 12 disposed on the placement seat 11. Multiple limiting blocks 12 are arranged at intervals along the circumference of the placement seat 11, forming a limiting space 13 for limiting the material 200. A second through hole 111 is formed in the placement seat 11. The multiple limiting blocks 12 limit the material 200 from multiple directions, thereby improving the limiting effect on the material 200, stabilizing the position of the material 200 during the pressing process, and thus improving the stability of the operation.

[0040] In some embodiments, the shape of the limiting space 13 is adapted to the outer contour of the material 200, that is, multiple limiting blocks 12 surround to form a contoured cavity for accommodating the material 200. Since the contoured cavity is highly consistent with the outer contour of the material 200, it provides the maximum contact area, eliminates the slight shaking or rotational freedom that may exist in the material 200 during the positioning process, and the simultaneous contact constraint of multiple complex curved surfaces can accurately and uniquely fix the material 200 in the expected position and direction.

[0041] Furthermore, the operator only needs to place the material 200 into the shape-matching contour cavity, and it will automatically and quickly fall into the single correct position. This eliminates the need for tedious adjustments and alignment of multiple locating pins or reference surfaces, significantly reducing clamping time, operational difficulty, and error rate.

[0042] In some embodiments, the limiting block 12 has an abutment surface 121 that abuts against the material 200, and the abutment surface 121 is adapted to the shape of the outer surface of the material 200. By providing multiple abutment surfaces 121, the material 200 can be precisely and uniquely fixed in the expected position and orientation when multiple abutment surfaces 121 simultaneously contact the constraint.

[0043] In some embodiments, the carrier 10 and the turntable 20 are detachably connected, allowing for quick assembly and disassembly of the carrier 10 and the turntable 20. When a single carrier 10 becomes jammed due to material 200 or deformed by collision, only the faulty carrier 10 is disassembled, while the remaining stations on the turntable 20 continue to operate, thereby significantly reducing maintenance costs and downtime losses. Optionally, the carrier 10 can be detachably connected to the turntable 20 via a positioning pin and a quick-lock mechanism.

[0044] This utility model also proposes a vehicle lamp production equipment, which includes a feeding device. The specific structure of the feeding device is as described in the above embodiments. Since this vehicle lamp production equipment adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0045] In summary, when the feeding device of this application is in use, the drive structure 30 drives the turntable 20 to rotate so that the carrier 10 moves sequentially to each working station 300. By arranging each working station 300 at intervals along the circumference of the turntable 20, compared with the linear layout where the material 200 is transported in a straight line, the turntable 20 transmission method occupies less space and has a more compact structure, which is beneficial to reducing the space occupied by the feeding device. In addition, each working station 300 is equipped with an independent position detection structure 40. Each position detection structure 40 directly detects whether the material 200 entering the corresponding working station 300 has moved into place, avoiding the accumulation of errors caused by traditional single detection points or only detecting the displacement of the transmission belt, thereby improving the accuracy of material 200 arrival detection.

[0046] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
