Description

Technical Field

[0001] The present invention relates to the technical field of light strip quality inspection, and in particular to a flexible light strip quality inspection device. Background Art

[0002] LED light strip refers to LEDs assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is named because its product shape resembles a strip; Existing LED light strips need to be quality inspected after production. The bending ability of the light strip is a weight item that needs to be inspected. When inspecting the bending resistance of the existing light strips, the copper wires at the lamp beads inside the light strips are bent. If the copper wires inside the light strips are damaged due to excessive stress during bending, the light intensity of the lamp beads at that location will be significantly reduced, thereby reflecting whether the copper wires inside the light strips are damaged due to bending. Since the lamp beads inside the light strips are arranged in parallel, the lamp beads of the light strips need to be bent one by one, thereby reducing the efficiency of the light strip quality inspection. Therefore, a flexible light strip quality inspection device is proposed to solve the above problem. Summary of the invention

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution is provided with a bending roller, a detection box and a power supply assembly. By making the light strip wrap around the bending roller, the light strip passing through the bending roller can be bent, thereby realizing the automatic bending function of the light strip to be tested. The bent light strip passes through the detection box, and the detection box can detect the light intensity of the light strip.

When the light strip moves into the detection box 3, the driving motor stops working. At this time, the light strip no longer moves. The light sensor 12 can detect the light intensity emitted by the lamp beads of the light strip located inside the detection box 3, and transmit it to the controller 13 for comparison with the standard light intensity. If the detected light intensity is lower than the standard value, it means that the copper wire inside the light strip is damaged due to bending, which further indicates that the light strip's anti-bending ability is unqualified.

[0015] Marking components are provided on both sides of the detection box 3; the marking components include mounting rails 301 fixedly connected to the two ends of the detection box 3 and elastic clips 10 slidably connected inside the mounting rails 301, a marking pen 9 is clamped inside the elastic clip 10, and an electric push rod 11 is installed on the side wall of the detection box 3, and the output end of the electric push rod 11 is fixedly connected to the elastic clip 10.

[0016] It should be noted that: if the bending resistance of the light strip is unqualified, the controller 13 controls the electric push rod 11 to work, and the electric push rod 11 drives the elastic clip 10 to slide along the mounting slide rail 301, thereby driving the marking pen 9 to move and draw lines on the light strip, thereby significantly reducing the range of damaged copper wires on the light strip, making it easier for quality inspectors to further quickly screen specific damaged copper wires (there are two groups of marking components, and damaged copper wires exist in the range between the lines on the light strip).

[0017] An adapter plate 501 is rotatably provided at one end of the winding roller 5, a support plate is fixedly connected to the side wall of the adapter plate 501, a power supply assembly is provided on the support plate, a driving motor for driving the rotation of the winding roller 5 is installed at the other end of the winding roller 5, a power supply rail 16 is provided on the inner side of the winding roller 5, one end of the power supply rail 16 is fixedly connected to the adapter plate 501 through a connecting rod, a socket 502 is provided on the surface of the winding roller 5, a circular through hole is provided at the bottom end of the socket 502, a grounding plug shaft 1 is fixedly connected in the circular through hole 5, the bottom end of the grounding plug shaft 15 is fixedly connected with the power-connecting slider 14 which is slidably connected with the power-connecting slide rail 16, a wire passing opening 503 is provided at the center of the adapter plate 501, and the power supply assembly comprises an ammeter 7, a sliding rheostat 6 and a test power supply 8 which are mounted on the support plate, the positive pole of the test power supply 8 is connected in series with the ammeter 7, the power-connecting slide rail 16 and the sliding rheostat 6 through a wire, the negative pole of the test power supply 8 is connected with a socket connected with the light strip through a wire, and the socket is electrically connected with the sliding rheostat 6 through a wire.

[0018] It should be noted that a display screen is installed on the side wall of the detection box 3 to display the damage degree of the copper wire.

[0019] It is worth noting that: the driving motor drives the winding roller 5 to rotate intermittently, thereby realizing the intermittent winding function of the light strip, providing time for the quality inspection of the light strip; It is worth noting that the two side walls of the power rail 16 have conductive properties, and the bottom is made of insulating material.

[0020] It should be noted that the current passing through the light strip can be changed by the sliding rheostat 6. Under the action of the ammeter 7, the current value passing through the light strip can be specifically detected, and then the light intensity of the light strip under the corresponding current value can be controlled. The controller 13 counts the qualified rate when the light intensity of the light strip under different current values ​​is compared with the corresponding standard light intensity, and sends the qualified rate to the display screen for display, which can reflect the degree of damage to the copper wire; If the lamp beads on the light strip go out directly, it means that the copper wire at the lamp bead is completely damaged.

[0021] When the present invention is used, the light strip is wound around the bending roller 2 for one circle, and passed through the detection box 3, so that one end of the light strip is inserted into the socket 502 on the winding roller 5, and the plug at the end of the light strip is plugged into the grounding plug shaft 15, so as to realize the electrical connection function between the light strip and the power supply slide rail 16, so that the other end of the light strip is connected to the socket, so that the light strip is connected to the power supply component; Turn on the drive motor, and the drive motor drives the winding roller 5 to rotate intermittently to realize the intermittent winding function of the light strip. Under the action of the bending roller 2, the light strip passing through the bending roller 2 can be bent to realize the function of automatically bending the light strip to be tested. When the winding roller 5 stops rotating, the quality inspector can manually turn the pointer on the sliding rheostat 6, and cooperate with the ammeter 7 to change the current value inside the light strip, so that the light strip can emit light of different intensities under the action of different current values. Under the action of the light sensor 12, the light intensity of the light strip inside the detection box 3 can be detected. The light sensor 12 transmits the light intensity value to the controller 13 for comparison. If the light intensity of the lamp beads in the detection box 3 is weaker than the standard light intensity, , indicating that the copper wire inside the light strip is damaged due to bending (the controller 13 will count the qualified rate of the light strip when comparing the light intensity at different current values ​​with the corresponding standard light intensity, and send the qualified rate to the display screen for display, which can reflect the degree of damage to the copper wire. If the lamp beads on the light strip are directly extinguished, it means that the copper wire at the lamp beads is completely damaged). The controller 13 controls the electric push rod 11 to work, and the electric push rod 11 drives the elastic clamp 10 to slide along the mounting slide rail 301, and then drives the marker 9 to move and draw a line on the light strip, thereby significantly reducing the range of damaged copper wires on the light strip, making it easier for quality inspectors to further quickly screen specific damaged copper wires, thereby realizing the automatic detection function of the light strip's anti-bending performance.
