[0015] This utility model improves the positioning accuracy of LED beads through the precise positioning design of a rotary feeding platform. The bead slots on the turntable are precision-machined, and the vision component on the chip-picking platform monitors and compensates for the position of each bead in real time, ensuring accurate pickup by the placement head. This effectively solves quality problems such as missing or upright LEDs found in traditional feeding methods. The rotary feeding platform uses a continuous rotary feeding method, which increases the feeding speed compared to traditional intermittent feeding. The dual detection mechanism of the fiber optic component ensures the continuity and stability of the feeding, avoiding production interruptions caused by material shortages or repeated feeding.

The fiber optic component ensures that each slot has an LED bead that has been properly picked up, preventing missed placement and duplicate placement. The waste bin and suction pipeline form an automatic rejection system that can quickly remove defective products, ensuring that only qualified products enter the next process.

Detailed Implementation
[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] As shown in Figures 1-4 , the high-precision positioning feeder for lamp bead bulk material mainly includes a rack 1, a feeding and sorting module 2, and a rotating feeding platform 3. The rack 1 is built with aluminum alloy profiles, which has sufficient rigidity and stability. The feeding and sorting module 2 and the rotating feeding platform 3 are installed side by side on the rack 1 and connected through a conveying channel.
[0026] As shown in Figure 2 and Figure 3 , the feeding and sorting module 2 includes a vibrating feeder 21 and a detection turret 22. The vibrating feeder 21 adopts electromagnetic vibration mode, which can orderly arrange and convey the bulk LED lamp beads to the detection turret 22 by adjusting the vibration frequency and amplitude. The detection turret 22 is equipped with a visual detection system, which can detect the size, appearance, polarity, etc. of the lamp beads, screen out qualified products and adjust them to the correct direction, and then convey the qualified lamp beads to the discharging position 341 of the rotating feeding platform 3 through the conveying mechanism.
[0027] It should be noted that the structure and working principle of the vibrating feeder and the detection turret are prior art, which will not be described here.
[0028] Referring to Figure 3 and Figure 4 , the rotating feeding platform 3 includes a support 31, a rotating motor 32, a turntable 33, and a top plate 34. The top plate 34 is fixed on the top of the support 31 and has a circular avoiding groove 343 in the middle. The turntable 33 is installed in the circular avoiding groove 343 and is supported by a precision bearing to ensure smooth rotation. The rotating motor 32 is a servo motor that drives the turntable 33 to make intermittent rotary motion through a synchronous belt.
[0029] The turntable 33 has a plurality of lamp bead acupoints evenly distributed in the circumferential direction. Each acupoint is precisely machined, with a size matching the LED lamp bead and a depth precisely controlled to ensure accurate positioning of the lamp bead. The top plate 34 is provided with a discharging position 341 and a taking position 342, which correspond to the outlet of the feeding and sorting module 2 and the taking position of the mounting process, respectively.
[0030] As shown in Figure 4 , the detection fiber assembly includes a first detection fiber 381 and a second detection fiber 382. The first detection fiber 381 is arranged on the feeding side of the taking position 342 and is used to detect whether there is a lamp bead in the acupoint; the second detection fiber 382 is arranged on the discharging side of the taking position 342 and is used to detect whether the lamp bead is taken normally. This double detection mechanism ensures the reliability of the feeding.
[0031] As shown in Figure 4As shown, the waste bin 36 is installed outside the support 31 and connected with the suction port on the top plate 34 through the suction pipeline 37. When the visual component detects the defective product, the control system controls the rotary table 33 to rotate the defective product to the suction port position, and the defective product is sucked into the waste bin 36 through vacuum suction.
[0032] Working process:
[0033] The bulk LED lamp beads first enter the vibration feeder 21, and are sent to the detection rotary tower 22 after vibration sorting. The detection rotary tower 22 detects and adjusts the direction of each lamp bead, and the qualified products are sent to the discharge position 341 of the rotary feeding platform 3.
[0034] The rotary table 33 is intermittently moved under the drive of the rotary motor 32, and when the lamp bead position is rotated to the discharge position 341, the lamp bead is received from the feeding and sorting module 2. Then the rotary table rotates to take the lamp bead to the taking position 342. In this process, the visual component detects the lamp bead, and if a defective product is found, the rejection program is started.
[0035] The mounting head picks up the lamp bead from the taking position 342 for mounting. The detection optical fiber component monitors the feeding state in real time to ensure that the production is continuously and stably carried out.
[0036] Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.
