[0002] A lamp bead feeder is a device used to convey LED lamp beads to a packaging or placement machine. It usually consists of components such as a circular vibrator, a linear vibrator, a transfer robotic arm, and a conveying track. During operation, the circular vibrator and the linear vibrator cooperate to arrange and convey the lamp beads one by one into the grasping range of the transfer robotic arm. Subsequently, the transfer robotic arm precisely transfers the lamp beads onto the conveying track, and the conveying track is connected to the subsequent packaging equipment or placement machine.

[0003] However, conventional lamp bead feeders do not have a lamp bead detection function. Once the conveyed lamp beads have quality defects or flaws, they will be directly integrated into the finished product materials, inevitably causing damage to the functions of the finished product materials and affecting the overall production yield and user experience.

[0006] Further, the detection component includes a detection positioning seat disposed on the support base. The detection positioning seat is provided with a detection positioning groove, and the detection positioning seat is provided with a plurality of detection probes, and the plurality of detection probes face the detection positioning groove.

[0014] 1. In a lamp bead detection mechanism of the utility model, by arranging a sorting and detection structure and a handling structure, when the lamp bead detection mechanism operates, the handling structure transports the lamp beads supplied to the sorting and detection structure. The sorting and detection structure sequentially detects, corrects the deviation and retests the lamp beads.

[0028] Reference Figure 1 as well as Figure 2 A lamp bead detection mechanism is arranged in a feeder, comprising a support base 1, and also comprising a sorting detection structure 2 and a conveying structure 3 arranged on the support base 1. When the lamp bead detection mechanism is in operation, the conveying structure 3 conveys the fed lamp beads to the sorting detection structure 2, and the sorting detection structure 2 sequentially detects, corrects and re-tests the lamp beads to prevent abnormal or defective lamp beads from entering subsequent processes, thereby improving product yield.

[0029] Specifically, the transport structure 3 includes a support seat 31 and a suction cup assembly 32 arranged on the support seat 31. The support seat 31 can be arranged on the support base 1 or independently. The suction cup assembly 32 includes a linear guide rail 321 arranged on the support seat 31. The linear guide rail 321 is slidably connected with a suction cup bracket 322. The suction cup bracket 322 is provided with a plurality of vacuum suction nozzles 323 facing the sorting and detection structure 2. The linear guide rail 321, the suction cup bracket 322 and the vacuum suction nozzle 323 are located above the sorting and detection structure 2. In this embodiment, there are eight vacuum suction nozzles 323, and the eight vacuum suction nozzles 323 are distributed on the suction cup bracket 322 in groups of two each. The four groups of vacuum suction nozzles 323 have the same structure and correspond to different workstations. The first group of vacuum suction nozzles 323 is located above the discharge end, and the other three groups of vacuum suction nozzles 323 are located above the sorting and detection structure 2. The interval between the two vacuum suction nozzles 323 in each group is 10-16mm.

[0030] Driven by the linear guide rail 321, the suction cup bracket 322 will drive four groups of vacuum nozzles 323 to move simultaneously, and the four groups of vacuum nozzles 323 will drive the materials to enter different workstations in sequence. In addition, the handling structure 3 also includes a sensor component 33 and a vacuum pressure gauge 34 for detecting the position of the suction cup assembly 32. The sensor component 33 includes a sensor arranged on the support seat 31. The suction cup bracket 322 is provided with a sensing end for cooperating with the sensor. When the suction cup bracket 322 moves into place, the sensor will detect the sensing end and thus know that the suction cup bracket 322 is in place. The vacuum pressure gauge 34 is connected to the suction cup assembly 32, and is used to detect and display the vacuum pressure value of each vacuum nozzle 323.

[0031] Reference Figure 2, the sorting and detection structure 2 is located below the handling structure 3. Driven by the handling structure 3, the lamp bead materials will enter the sorting and detection module in sequence. The sorting and detection module includes a detection component 21, a deviation correction component 22, a re-inspection component 23, and a collection component 24 arranged on the support base 1. The detection component 21 is used to perform the first detection on the polarity of the lamp bead materials; according to the detection results of the detection component 21, the deviation correction component 22 corrects the lamp bead materials. The corrected lamp bead materials enter the re-inspection component 23 for re-inspection of the polarity. The materials that pass the detection will enter the discharging module, while the materials that do not pass the detection are collected by the collection component 24.

[0032] Refer to Figure 2 and Figure 3 , specifically, the detection component 21 is located below the second group of vacuum suction nozzles 323. The detection component 21 includes a detection positioning seat 211 arranged on the support base 1. The detection positioning seat 211 is provided with a detection positioning groove 2111 for placing lamp beads; at the same time, a number of detection probes are arranged on the detection positioning seat 211. The detection probes are located below the detection positioning groove 2111 and face the detection positioning groove 2111. After the vacuum suction nozzle 323 places the lamp bead materials on the detection positioning seat 211, the lamp bead materials will be limited and fixed in the detection positioning groove 2111. At the same time, the polarity points of the lamp bead materials will contact the detection probes. The detection probes are connected to external detection equipment. Just by energizing and testing the polarity points of the lamp bead materials through the detection probes, it can be known whether the polarity points of the lamp bead materials are qualified, and the orientation of the lamp bead materials can also be known.

[0033] Refer to Figure 2 and Figure 4, the alignment component 22 is located below the third group of vacuum suction nozzles 323. The alignment component 22 includes an alignment positioning seat 221 disposed on the support base 1. The alignment positioning seat 221 is rotatably connected to an alignment rotating seat 222. The alignment rotating seat 222 is provided with an alignment positioning groove 2221 for placing the lamp beads. The alignment positioning seat 221 is provided with a rotation driving component (not shown in the figure) for driving the alignment rotating seat 222. The rotation driving component may specifically be a motor. After the lamp bead material is detected by the detection component 21, it will be carried and placed into the alignment positioning groove 2221 of the alignment rotating seat 222 under the drive of the suction cup component 32. According to the detection result of the detection component 21, the rotation driving component drives the alignment rotating seat 222 to rotate so that the lamp bead material faces the same side. In addition, in order to confirm the rotation angle of the alignment rotating seat 222, the alignment component 22 further includes an alignment inductor 2211 disposed on the alignment positioning seat 221. The alignment rotating seat 222 has an induction portion 2222 for cooperating with the alignment inductor 2211. In this embodiment, the induction portion 2222 is grooves disposed on opposite sides of the outer edge of the alignment rotating seat 222. When the alignment rotating seat 222 performs alignment rotation, the alignment inductor 2211 senses the rotation of the induction portion 2222 to verify the rotation of the alignment rotating seat 222.

[0034] The re-inspection component 23 is located below the fourth group of vacuum suction nozzles 323. The re-inspection component 23 includes a re-inspection positioning seat 231 disposed on the support base 1. The re-inspection positioning seat 231 is provided with a re-inspection positioning groove 2311 for placing the lamp beads. The re-inspection positioning seat 231 is provided with a plurality of re-inspection probes. The re-inspection probes are located below the re-inspection positioning groove 2311 and face the re-inspection positioning groove 2311. Under the drive of the suction cup component 32, the lamp bead material is carried from the alignment component 22 to the re-inspection positioning groove 2311 of the re-inspection component 23 and contacts the re-inspection probes. The re-inspection probes are connected to an external detection device. By energizing the polarity points of the lamp bead material through the re-inspection probes, the lamp bead material can be re-inspected. By re-inspecting the lamp bead material, on the one hand, it can verify again whether the polarity points of the lamp bead material are operating normally, and on the other hand, it can verify whether the orientation of the lamp bead material is correct after passing through the alignment component 22.

[0035] Refer to Figure 2 and Figure 5, in order to save space and make the feeder structure compact, the collection assembly 24 is located above the re-inspection assembly 23. The collection assembly 24 includes a collection base body 241 arranged on the support base 1. The collection base body 241 is provided with a relief groove 2411 for cooperating with the suction cup assembly 32. The relief groove 2411 has an NG material hole 2412, and the NG material hole 2412 is connected to an NG material channel 242. By setting the collection assembly 24 in this way, when the fourth group of vacuum suction nozzles 323 move the bead materials from the re-inspection assembly 23 to the discharge module, they will pass through the relief groove 2411 of the collection assembly 24. The bead materials that pass the verification in the re-inspection assembly 23 will be transported to the discharge module through the relief groove 2411, while the bead materials that do not pass the verification will stay when passing through the relief groove 2411 and be placed into the NG material hole 2412, and finally enter the NG material channel 242 to be collected for subsequent processing.

[0036] Referring to Figure 6 , it can be understood that the bead detection mechanism of the present application can be arranged in the feeder, so as to detect and sort the beads during the feeding process, thereby preventing abnormal or defective beads from entering the subsequent processes; the bead detection mechanism of the present application can also be set separately to detect and sort the beads, and can be selected according to actual needs.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0038] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
