Description

Technical Field

[0001] The utility model relates to the technical field of LED production, in particular to an LED tape braiding machine. Background Art

[0002] With the development of LED technology, LED packaging devices are more and more widely used in the lighting field. With the internal circulation of the LED market, innovation is not only necessary to ensure product quality, but also to improve customer satisfaction index and competitiveness. The production steps of LED include taping and spectrometry, the purpose of which is to sort each SMD onto the material tape and finally form a tape reel.

[0003] In the existing technology, only the CCD camera at the transplanting mechanism is used to detect and identify the appearance of the SMD when transplanting it. If a defective SMD is detected, the SMD is discarded. However, the adhesive condition at the bottom of the SMD cannot be detected and identified. As a result, many SMDs with adhesive on the bottom appear in the finished tape roll, which will affect the performance of the finished LED. In addition to the quality of the SMD itself, the running process of the tape also needs to be monitored for the complete operation of the taping machine, because the tape flows through a reel and a conveyor belt, which may cause the problem of deviation.

[0012] According to one aspect of the above technical solution, the LED braiding machine also includes a machine platform, a first support plate arranged on the machine platform, a second support plate located above the machine platform, and a third support plate arranged at the braiding mechanism.

When the SMD is transported from the feeding mechanism to the transferring mechanism, the transferring mechanism will send the SMD from the feeding mechanism to the calibration and alignment. After the calibration and alignment, the SMD will be transported to the material belt. During this process, the first CCD camera located near the suction cup can accurately monitor whether there is any defect in the appearance of the SMD, thereby completing the first level of detection and identification. When the suction cup and the suction nozzle transport the SMD, the vertical moving component will drive the suction cup and the suction nozzle to move up and down. During the up and down movement, the bottom of the SMD on the suction nozzle will be exposed to the detection range of the third CCD camera, and then the adhesive condition of the bottom of the SMD will be detected, thereby completing the second level of detection and identification. When the SMD is fixed on the material belt for transportation, the second camera located near the material belt will also detect the condition of the material belt itself, whether there is any deviation, etc., thereby completing the third level of detection and identification.

The braiding mechanism includes a first reel 71 and a second reel 72 arranged opposite to each other, a material strip 70 connected to the first reel 71 and the second reel 72, and a sealing machine 31 located above the material strip 70. The transplanting mechanism 60 includes a vertical moving component, a rotary moving component connected to the vertical moving component, a suction cup 64 connected to the rotary moving component, and a suction nozzle 65 provided on the suction cup 64. The LED braiding machine also includes a detection mechanism, which includes a first CCD camera 41 located near the suction cup 64, a second CCD camera 32 located near the material strip 70, and a third CCD camera 21 located below the suction cup 64. The first CCD camera 41 is used to detect the appearance of the SMD, the second CCD camera 32 is used to detect defects in the braiding mechanism, and the third CCD camera 21 is used to detect the adhesive condition of the bottom of the SMD.

[0029] It can be understood that the present invention sets a detection mechanism. Specifically, the detection mechanism includes a first CCD camera 41 arranged near the suction cup 64, a second CCD camera 32 arranged near the material belt 70, and a third CCD camera 21 located below the suction cup 64. When the SMD is transported from the feeding mechanism 50 to the transplanting mechanism 60, the transplanting mechanism 60 will send the SMD from the feeding mechanism 50 to the calibration and alignment (the calibration and alignment mechanism is not shown in the figure and belongs to the prior art). After the calibration and alignment, the SMD is transported to the material belt 70. During this process, the first CCD camera 41 arranged near the suction cup 64 is used to detect the position of the SMD. The appearance of the SMD can be accurately monitored to see if there are any defects, completing the first level of detection and identification. When the suction cup 64 and the suction nozzle 65 transport the SMD, the vertical moving component will drive the suction cup 64 and the suction nozzle 65 to move up and down. During the up and down movement, the bottom of the SMD on the suction nozzle 65 will be exposed to the detection range of the third CCD camera 21, and the adhesive condition of the bottom of the SMD will be detected, thereby completing the second level of detection and identification. When the SMD is fixed on the material belt 70 for transportation, the second camera set near the material belt 70 will also detect the condition of the material belt 70 itself to see if there is any deviation, thereby completing the third level of detection and identification.

[0030] The utility model provides three-level detection by using three CCD cameras, which greatly improves the yield rate.

[0031] Specifically, in this embodiment, the feeding mechanism 50 includes a vibration plate 51 and a loading track 5252 connected to the vibration plate 51 , and the terminal end of the loading track 5252 is located below any one of the suction nozzles 65 .

[0032] It can be understood that, through the vibration of the vibration plate 51 , the unnecessary SMDs can be transported to the loading track 5252 in an orderly manner, ready for transplantation by the transplanting mechanism 60 .

[0033] Furthermore, the vertical moving assembly includes a vibrator 6161 and a connecting piece 62 connected to the vibrator 6161, and the connecting piece 62 is fixedly connected to the rotary moving assembly; the rotary moving assembly includes a protective shell 63 fixedly connected to the connecting piece 62, and a rotating motor provided in the protective shell 63, and the rotating motor is fixedly connected to the suction cup 64; there are multiple suction nozzles 65, and the multiple suction nozzles 65 are arranged in a circular array along the outer edge of the suction cup 64.

[0034] It can be understood that when the vibration machine 6161 is in action, it will drive the connecting part 62 to move up and down a short distance, so that the connecting part 62 drives the rotating moving component together with the suction cup 64 and the suction nozzle 65 to move up and down, thereby realizing the clamping of the SMD. After the suction nozzle 65 clamps the SMD, the rotary motor in the protective shell 63 drives the suction cup 64 together with the suction nozzle 65 to rotate, so that the suction nozzle 65 drives the SMD to move to calibrate the positioning, and then the rotation of the rotary motor drives the SMD to move to the material belt 70. Through high-speed up and down movement and rotation, the SMD can be quickly processed.

[0035] Furthermore, the LED tape machine also includes a film roll conveying mechanism (belonging to the existing technology, not shown in the figure), and the sealing machine 31 includes a cylinder 311 and an extrusion part 312 connected to the cylinder 311. The extrusion part 312 is used to make the film roll fit the SMD on the material tape 70.

[0036] It can be understood that after the SMD is fixed to the material tape 70, the film roll conveying mechanism will cover the film roll onto the material tape 70, and then drive the extrusion part 312 through the cylinder 311 to cover the film roll on the SMD. After the second reel 72 rolls up the material tape 70, a tape roll is formed.

[0037] Furthermore, the LED braiding machine also includes a machine 10, a first support plate 20 provided on the machine 10, a second support plate 40 located above the machine 10, and a third support plate 30 provided at the braiding mechanism, the feeding mechanism 50, the transplanting mechanism 60 and the braiding mechanism are all located on the machine 10; the first CCD camera 41 is fixedly connected to the bottom of the second support plate 40 through a first fixed shell, the second CCD camera 32 is fixedly connected to the third support plate 30 through a second fixed shell, and the third CCD camera 21 is fixedly connected to the first support plate 20 through a third fixed shell.
