Description

Technical Field

[0001] This utility model relates to the field of flexible light strip detection technology, and in particular to an automatic reel detection device for flexible light strip lighting. Background Technology

[0002] Flexible LED strips are characterized by their soft light emission and good flexibility, and their applications are becoming increasingly widespread, making them very popular.

[0003] To ensure that every LED in a flexible LED strip lights up properly before leaving the factory, existing factories inspect the strips and then transport the inspected reels. A common technique involves installing a socket on the winding shaft of the flexible LED strip. The positive and negative wires of the strip are inserted into the socket, and then workers manually inspect the strips to identify defective products that fail to light up or whose brightness is inconsistent with the other LEDs.

[0004] However, this model has the following drawbacks:

[0005] (1) The positive and negative terminals of the flexible light strip cannot be firmly inserted into the socket. When the rewinding shaft rotates, the positive and negative terminals of the flexible light strip are easily detached from the socket.

[0006] (2) Relying solely on staff to manually observe whether the LED beads are emitting light normally is not only harmful to the staff's eyesight, but also easily leads to errors due to human factors such as the staff's eyesight and concentration during work, thus affecting the accuracy of the test.

[0007] (3) Manual sorting is inefficient and seriously affects the speed of product delivery.

[0008] Ultimately, this severely impacts the factory's profitability and the quality of its products.

[0009] The utility model patent application, with application number 202321958685.1 and titled "A wiring device for an LED strip reeling machine and an LED strip reeling machine," describes a wiring device that securely connects the positive and negative terminals of the flexible LED strip, facilitating inspection and reeling by workers. However, it still fails to resolve the issue of relying on manual observation of whether the LED beads are emitting light correctly.

[0010] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0033] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0034] like Figures 1 to 4 As shown in this embodiment, an automatic reel detection device for flexible LED strip lighting includes:

[0035] The housing 1 has a winding shaft 12 with two through holes 121 for electrical connection to the positive and negative terminals of the flexible LED strip 2. A reel 3 is mounted on the winding shaft 12. When the positive and negative terminals of the flexible LED strip 2 are electrically connected through the two through holes 121, the LEDs of the flexible LED strip 2 illuminate, allowing for brightness testing. Simultaneously, the flexible LED strip 2 is securely connected to this invention.

[0036] A first driving device is disposed inside the housing 1, and the first driving device is connected to the winding shaft 12 in a transmission manner;

[0037] A guide pressing mechanism 14 is provided on the housing 1, and the flexible light strip 2 is wound around the take-up shaft 12 after passing through the guide pressing mechanism 14;

[0038] The detection mechanism 15 is disposed on the housing 1 and is used to detect the brightness of the LED beads on the flexible LED strip 2;

[0039] The control system is located inside the housing 1 and is electrically connected to the first drive device, the guide pressing mechanism 14 and the detection mechanism 15 respectively.

[0040] The flexible LED strip lighting automatic reel detection device proposed in this embodiment has a relatively high degree of automation. It eliminates the need for manual observation of whether the LED beads are emitting light normally, and quickly and accurately detects and reels the flexible LED strip, thereby improving the efficiency and accuracy of lighting detection.

[0041] Furthermore, a power supply is provided inside the outer casing 1. The power supply is electrically connected to the control system to supply power to the first driving device, the guide pressing mechanism 14 and the detection mechanism 15, enabling the present invention to operate in an integrated manner.

[0042] The detection mechanism 15 is located above the flexible light strip 2 and includes at least a second driving device and a detection head 151. The driving end 152 of the second driving device is connected to the detection head 151 to drive the detection head 151 to move up and down. When the flexible light strip is lit, the detection head descends to a fixed position to perform brightness tests on the passing LED beads. When a defective LED bead is detected or the entire flexible light strip 2 has been inspected, the detection head 151 returns to its original height.

[0043] Furthermore, the guiding and pressing mechanism 14 includes at least a first rotating shaft 141, a first guide wheel 142, and a limiting wheel 143. The first rotating shaft 141 is disposed on the outer shell 1, the first guide wheel 142 is disposed on the first rotating shaft 141 and close to the outer shell 1, and the limiting wheel 143 is disposed on the first rotating shaft 141 and located outside the first guide wheel 142. The diameter of the limiting wheel 143 is larger than the diameter of the first guide wheel 142. The flexible light strip 2 is wound backwards onto the take-up shaft 12 via the first guide wheel 142, and the flexible light strip 2 is confined between the limiting wheel 143 and the outer shell 1. The limiting wheel 143 can be adjusted according to the width of the flexible light strip 2, thereby allowing the guiding and pressing mechanism 14 to adapt to light strips of different widths, increasing the applicability of this utility model.

[0044] Furthermore, the guiding and pressing mechanism 14 includes a third driving device, a pressing wheel 144, and a connecting mechanism 145. The pressing wheel 144 is located above the first guide wheel 142. The third driving device is connected to the pressing wheel 144 to drive its rotation. The pressing wheel 144 can press the flexible light strip 2 onto the first guide wheel 142. The driving end 152 of the second driving device is connected to the third driving device through the connecting mechanism 145. The second driving device can drive the third driving device and the pressing wheel 144 to move up and down through the connecting mechanism 145. Under the action of the third driving device, the pressing wheel 144, and the first guide wheel 142, the flexible light strip 2 can be prevented from folding during flow, thus allowing for better winding.

[0045] Furthermore, the guiding and pressing mechanism 14 also includes a second rotating shaft 146 and a second guide wheel 147. The second rotating shaft 146 is located at the front end of the first rotating shaft 141 and on the outer casing 1, and the second guide wheel 147 is disposed on the second rotating shaft 146. Under the action of the second rotating shaft 146 and the second guide wheel 147, the flexible light strip 2 can enter the present invention in a straight line, allowing the detection mechanism 15 to detect the flexible light strip.

[0046] Furthermore, a support plate 148 is provided between the first rotating shaft 141 and the second rotating shaft 146, on the outer casing 1. The flexible LED strip 2 located between the first guide wheel 142 and the second guide wheel 147 can be supported on the support plate 148. A pressure plate 149 is provided on the lower side of the connecting mechanism 145, and the pressure plate 149 can rise and fall with the connecting mechanism 145. Under the combined action of the support plate 148 and the pressure plate 149, the LED strip remains straight and at the same height between the first guide wheel 142 and the second guide wheel 147, which is beneficial for the detection mechanism 15 to more thoroughly detect each LED bead. When a defective LED bead is encountered, the pressure plate 149 can rise to a fixed position with the connecting mechanism 145, making it convenient for staff to pick out the defective LED beads.

[0047] Furthermore, a display screen 11, a switch assembly 13, and a voltage regulator 16 are provided on the outer casing 1. The display screen 11, the switch assembly 13, and the voltage regulator 16 are electrically connected to the control system. This makes the present invention easy to operate and reduces the technical requirements for operators.

[0048] Furthermore, an adhesive backing unwind roller 17 is provided below the second guide wheel 147 and on the outer casing 1. When the flexible light strip being tested needs adhesive backing in addition to the reel, the adhesive backing unwind roller 17 can be used to place the adhesive backing. Under the combined action of the pressure wheel 144 and the first guide wheel 142, the adhesive backing is pressed onto the back of the flexible light strip 2, thereby realizing the automated application of adhesive backing to the flexible light strip 2.

[0049] Furthermore, a buzzer is installed on the housing, and the buzzer is electrically connected to the control system. When the detection mechanism 15 detects a defective LED bead, the buzzer emits a bright sound to alert the staff to take action.

[0050] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
