Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a feeding device for an LED lamp head. Background Art

[0002] LED lamp beads (bulbs), full name light-emitting diode lamp beads, are a kind of semiconductor components. Under the action of appropriate voltage and current, LED lamp beads can emit light, with the advantages of high efficiency, low energy consumption, long life, environmental protection and energy saving. The light-emitting principle of LED lamp beads is based on the electroluminescent effect of PN junction. When the LED lamp beads are connected through an external circuit and current is passed through, the positive electrode (anode) and the negative electrode (cathode) will inject electrons and holes into the PN junction. Near the PN junction, electrons and holes will recombine, release energy and convert into photons (the basic unit of light), thereby generating visible light. Compared with other light sources, LED lamp beads have the advantages of low power consumption, durability, green environmental protection, and eye protection.

[0003] After the LED lamp beads complete the packaging process, they need to be tested and screened, that is, the packaged LED lamp beads need to be electrically and optically tested to screen out qualified products. The current common detection method is: place the lamp beads on the detection platform and power on, use a camera to shoot the light-emitting part, and then use computer software to identify the image to determine whether the light emission of the lamp beads is normal. In order to improve the efficiency of LED lamp beads in the testing process, automatic loading is generally used, and because the size of LED lamp beads is small, it is suitable to use a vibration plate to realize automatic sorting and loading. However, since LED lamp beads have the characteristics of diodes, that is, the current is unidirectional and conductive, and the vibration plate sorting cannot distinguish the positive and negative poles of LED lamp beads, the LED lamp beads that are loaded by the vibration plate also need to undergo a positive and negative identification process, otherwise the subsequent detection link will cause some LED lamp beads to fail to light up due to reverse power connection. Summary of the invention

[0004] The utility model provides an LED lamp head loading device, which solves the problem in the prior art that the positive and negative poles of LED lamp beads cannot be distinguished by the arrangement of vibration plates.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: a feeding device for an LED lamp head, wherein the LED lamp head is a SMD LED lamp head, the LED lamp head is composed of a wick and pins at the bottom thereof, and the overall shape is a regular rectangular parallelepiped structure, characterized in that: the feeding device comprises a feeding manipulator assembly, a linear vibration feeding assembly and a control module;

[0006] The feeding robot assembly is composed of a multi-axis servo module and a gripper module. The gripper module is composed of a rotating part and a flexible suction cup. The flexible suction cup is arranged vertically downward. The feeding robot assembly is used to grab the LED lamp head on the linear vibration feeding assembly and transfer it to other stations.

[0007] The linear vibration feeding assembly includes a linear vibrator and a guide rail member arranged on the upper side thereof, the guide rail member is provided with a guide groove, the contour of the guide groove is adapted to the outer contour of the LED lamp head, a baffle is provided at the end of the guide groove, and two electrode sheets spaced from each other are provided at the end of the bottom surface of the guide groove, the upper surface of the electrode sheet is flush with the bottom surface of the guide groove, and the two electrode sheets are insulated from the guide rail member;

[0008] The control module includes a detection power supply and a detection chip. The detection power supply is direct current and is electrically connected to the two electrode sheets. The detection chip can detect the current conduction state of the two electrode sheets.

[0009] The linear vibration feeding assembly of the utility model is installed at the discharge port of the existing vibration disk sorting device, so that the LED lamp holder output from the vibration disk sorting device can directly slide into the guide groove. Although the vibration disk cannot identify the positive and negative poles of the pins, it can reliably identify the distribution direction of the pins. All LED lamp holders in the guide groove keep the pins on both sides distributed on both sides. The high-frequency vibration effect of the linear vibrator will cause the LED lamp holders in the guide groove to have a slight up and down jump. The vibration direction is biased to one side, so that the LED lamp holders will slowly move to one side, and the LED lamp holders at the rear end will be held back by the baffle, and the pins of the LED lamp holders are located above the two electrode sheets. When the feeding robot arm assembly is ready to grab the LED lamp holder on the linear vibration feeding assembly, the multi-axis servo module will control the gripper module to move to just above the LED lamp holder resting on the baffle, and gently press the flexible suction cup on the LED lamp holder. The pins of the LED lamp holder are then When the two electrode sheets are reliably fitted with each other, the detection chip controls the detection power supply to energize the two electrode sheets. When the pin distribution direction of the LED lamp head matches the positive and negative poles of the two electrode sheets, the LED lamp head will be turned on, and the detection chip can detect the state of current generated by the two electrode sheets. Then the flexible suction cup turns on the negative pressure state, and the multi-axis servo module controls the gripper module to transfer the LED lamp head to the subsequent workstation; when the pin distribution direction of the LED lamp head does not match the positive and negative poles of the two electrode sheets, the LED lamp head will not be turned on, and the detection chip can detect that the two electrode sheets do not generate current. Then the flexible suction cup turns on the negative pressure state, and the multi-axis servo module controls the gripper module to transfer the LED lamp head to the subsequent workstation, and during the transfer process, the rotating part will drive the flexible suction cup to rotate 180 degrees, so that when the LED lamp head enters the subsequent workstation, its pin distribution direction is in the correct direction, and then the rotating part will rotate in the opposite direction and reset before the next grab.

[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The two electrode sheets supply power to the LED lamp holder, and the distribution direction of the LED lamp holder pins is determined by detecting whether a pathway is formed, and a rotating part is installed on the gripper module to rotate the LED lamp holder grasped by it, thereby correcting the arrangement direction of the LED lamp holder. The identification method is reliable and accurate, the overall structure is streamlined, and the cost is controllable. BRIEF DESCRIPTION OF THE DRAWINGS
