Description

Technical Field

[0001] The present invention relates to the technical field of lamp bead detection, and in particular to a detection device for LED lamp beads. Background Art

[0002] LED lamp beads, also known as LED chips or LED light emitters, are light-emitting diodes made from semiconductor materials. Their operating principle: LED light emission is based on the photoelectric effect of semiconductor materials. Its core component is the PN junction. When a forward voltage is applied to the LED lamp bead, electrons move from the N-type semiconductor region to the P-type region, where they recombine with holes, releasing energy that is converted into light energy, thereby emitting light. This process produces virtually no heat loss, resulting in high energy conversion efficiency and a long lifespan for LED lamp beads.

[0003] As for the inspection of LED lamp beads, common ones include, for example, packaging inspection: Check whether the packaging of the LED lamp beads is intact, and whether there are cracks, breakage, missing corners, bubbles, etc. The packaging material should be uniform, smooth, and free of impurities or defects. Pin inspection: Observe whether the pins are neat, without bending or oxidation. The pin welding points should be firm, without cold soldering or desoldering, and the pin conductivity test should be performed to observe whether the LED lamp beads light up. Color and brightness inspection: Observe whether the color of the lamp beads is consistent and the brightness is uniform under natural light. There should be no obvious difference in color between the lamp beads in the same batch, and the color deviation should not be visually distinguishable when compared with the standard sample.

[0004] Current LED lamp bead detection devices usually use tray-type assembly line detection, which places LED lamp beads on a conductive carrier, such as a tray with through holes that are compatible with the LED lamp beads, and ensures that the LED lamp bead pins are in contact with the tray. After the tray is powered on, the brightness of the LED lamp beads is determined. Although this method has high detection efficiency, it cannot ensure that the pins of all LED lamp beads are in full contact with the tray due to the large number of LED lamp beads during operation. In addition, during the assembly of LED lamp beads and the detection operation, an oxide layer is formed on the surface of the pins, which can easily cause poor contact. However, this situation does not mean that the current LED lamp beads are defective, which reduces the detection accuracy and also causes a great deal of product waste, increasing the production cost of LED lamp beads.

Figure 12 As shown, the first rack 101 and the second rack 103 can slide along the rack sleeve respectively. The detection device of the LED lamp bead also includes a cleaning component 11 embedded in the shell 2, and the cleaning component includes at least one dust removal brush 111 arranged on the active path of the lamp bead 6 to clean the dust on the surface of the lamp bead 6 on the active path, wherein the dust removal brush 111 is mainly arranged on the path where the lamp bead 6 rotates to the detection mechanism 8.

[0026] During specific implementation, first, the operator can control and turn on the detection device of the LED lamp bead through the controller. In some optional embodiments of the present invention, the controller can be set at any position on the surface of the housing 2 that is convenient for the operator to operate. The controller can be an MCU (Microcontroller Unit) chip to control the detection device of the LED lamp bead through the MCU chip, and the controller and the detection device of the LED lamp bead are electrically connected. The electrical connection includes a wired connection and a wireless connection. The wireless connection method includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, Zigbee, and the wired connection method includes but is not limited to a USB line connecting the detection device of the LED lamp bead to the controller. Then, the controller sequentially controls the motor 3 to turn on and drive the rotating frame 4 to rotate, the electrode rod 87 on the detection mechanism 8 to power on, and the camera 5 to turn on. When the rotating frame 4 is driven to rotate by the motor 3, the rotating frame 4 can sequentially drive the clamping mechanism 7 to clamp the lamp bead 6, and drive the detection mechanism 8 to contact the pins of the lamp bead 6 on the rotation path and power on, and so on.

[0027] Furthermore, the rotating frame 4 drives the clamping mechanism 7 to clamp the lamp beads 6. Specifically, the operator can place the lamp beads 6 one by one in the accommodating grooves on the extension arms along the through-hole grooves on the shell 2. It can be understood that there are 8 extension arms on the rotating frame 4, which can place 8 lamp beads 6 in sequence, and when one of the extension arms drives the lamp beads 6 to return to the through-hole groove after completing a circle, the operator can take it out and classify it according to the detection results. When any extension arm on the rotating frame 4 rotates to the through-hole groove, the sliding clamp 72 on the active path can be abutted by the extrusion block 74 fixed at this position and fixed to the shell 2 to push the sliding clamp 72 toward the The first compression spring 73 is used to hold the lamp 6 in place and the second compression spring 74 is used to hold the lamp 6 in place.

[0028] Furthermore, the driving detection mechanism 8 contacts the pins of the lamp beads 6 on the rotation path and powers on, specifically, Figure 7 Shown and Figure 8As shown, the detection mechanism 8 is fixedly arranged on the top of the shell 2, and a top block 81 extends toward the bottom of the detection mechanism 8 at the bottom of each extension arm on the rotating frame 4. When the rotating frame 4 rotates axially along the path, the top block 81 moves to the top of the moving member 83 and applies downward pressure to it. During the process, the moving member 83 pushes it in turn away from the second compression spring 84 on the side of the moving plate 86, and the second compression spring 84 is deformed and embedded in the fixed tube 82. At the same time, the moving member 83 drives the moving plate 86 to slide along the inclined slide groove track opened in the middle, so that the moving plate 86 moves toward or away from the side of the lamp bead 6. During the process, the moving plate 86 pushes the trapezoidal end head away from the side of the moving member 83 to drive the connecting frame 88 to move along its inclined track. Among them, since the connecting frame 88 is fixedly connected to the electrode rod 87, and the electrode rod 87 passes through the shell 2, since the electrode rod 87 passes through the shell 2 and is restricted in the Y-axis direction, the trapezoidal end head drives the connecting frame During the movement of 88 along its trajectory, the lateral force generated by it is transitioned into a driving force along the axial direction of the motor rod 88, that is, along the X-axis direction, so that the connecting frame 88 pushes the electrode rod 87 to move toward or away from the top lamp bead 6, and finally contacts the pins on both sides of the lamp bead 6 to realize the power-on operation. In addition, when the rotating frame 4 drives the lamp bead 6 through the detection mechanism 8, the top block 81 is separated from the contact with the moving part 83, and the second compression spring 84 restores its deformation to retract the electrode rod 87, waiting for the top block 81 on the other extension arm to move to the corresponding position and then activate the electrode rod 87. In addition, in some optional embodiments of the present invention, a drive switch can also be set on the rising path of the electrode rod 87 to control the power-on of the electrode rod 87. It can be understood that after the electrode rod 87 is lifted, the switch is activated to implement the power-on operation, which saves the energy consumption problem of the electrode rod 87 being in the on state for a long time to a certain extent.

[0029] In addition, in some optional embodiments of the present invention, in the process of driving the detection mechanism 8 to contact and power on the pins of the lamp beads 6 on the rotating path, in order to ensure the cleanliness of the pin surface on the lamp bead 6 and the sufficient contact between the pins on the lamp bead 6 and the detection mechanism 8 to improve the accuracy of the detection of the lamp bead 6, it also includes driving the friction mechanism 9 to implement dust removal protection for the pins of the lamp bead 6. Specifically, when the movable plate 86 is driven to move toward or away from the lamp bead 6, it can drive the guide block 85 to follow the movement. During the process, the guide block 85 drives its top inclined block 91 to push the pulley 93 located on its path to follow the movement, wherein the pulley 93 is connected to the sliding rod 92 and is perpendicular to each other, so that the sliding rod 92 is driven by the pulley 93 to drive the grinding plate 94 on the side close to the lamp bead 6 to move toward or away from the lamp bead 6. Figure 10 and Figure 11As shown, the position of the grinding plate 94 coincides with the bottom of the two pins on the lamp bead 6, so that before the pins of the lamp bead 6 are powered on, the contact area between the bottom of the pins and the electrode rod 87 is polished to remove the oxide layer or dust remaining at the bottom of the pins, thereby ensuring the smooth power-on of the subsequent pins to the greatest extent, improving the accuracy of the subsequent power-on contact, and ensuring the detection quality of the lamp bead 6. At the same time, the cleaning component 11 can be used to remove dust from the surface of the lamp bead on the active path to ensure the brightness of the subsequent lamp bead 6, avoid the situation where the brightness of the lamp bead 6 is dark due to dust covering the surface during the power-on process, eliminate interference from various external factors, further improve the detection accuracy of the subsequent lamp bead 6, and reduce false detection.

[0030] Furthermore, the pressing mechanism 10 is driven to press the lamp bead 6 before detection to ensure that the subsequent pins are fully in contact with the electrode rod 87. Specifically, when the sliding rod 92 moves toward or away from the side of the lamp bead 6, it can drive the first rack 101 fixed on its top to follow the movement. During the process, the first rack 101 drives the gear 102 in turn to drive the second rack 103 to slide in relative directions, and the second rack 103 directly drives the pressure plate 104 to move toward or away from the pins on both sides of the lamp bead 6, and press the pins. It should be noted that the pressure plate 104 adopts a trapezoidal structure design. During its movement toward the pins, the raised part can also be pushed along the lowest side of its trapezoidal inclined surface to realize the pin flattening operation, so that the subsequent pins can be fully in contact with the electrode rod 87, avoiding the situation where the pins are warped and cannot be powered on during the detection process, further improving the detection accuracy of the lamp bead 6, and reducing the detection error caused by misoperation.

[0031] In summary, the LED lamp bead detection device in the above-mentioned embodiment of the present invention can be linked with the clamping mechanism 7, the detection mechanism 8, the friction mechanism 9, and the pressing mechanism 10 respectively during the rotation process through the rotating frame 4, so that the clamping mechanism 7 is driven to clamp the lamp bead 6 on the rotating frame 4, the friction mechanism 9 is driven to fit with the bottom of the pin to realize the grinding of the power-on position of the bottom of the pin, the pressing mechanism 10 is driven to press the top of the pin to ensure that the pin is fully in contact with the detection mechanism 8, and the pin of the lamp bead 6 is driven to move to the top of the detection mechanism 8 and complete the power-on detection after contact, thereby improving the detection accuracy of the lamp bead 6, reducing the detection error caused by misoperation, and solving the problem that the current LED lamp bead detection device has poor detection accuracy, resulting in product waste and increased production cost of LED lamp beads.
