Description

Technical Field

[0001] This utility model relates to the field of LED strip manufacturing technology, specifically a reel for winding LED flexible LED strips. Background Technology

[0002] LED flexible light strips refer to LED light strips that use FPC flexible circuit boards as substrates. They can be bent and rolled arbitrarily, providing a good decorative effect. In practical applications, to facilitate the transportation of LED light strips, they are generally wound onto reels. Existing reel structures typically include a core section for winding the LED light strip and limiting plates on both sides of the core section. A positioning plate is located in the middle of the winding section, with positioning through holes for mounting to the drive shaft of the winding machine. Because the positioning plate is located in the middle between the two limiting plates, when the light strip is inserted into the winding section during packaging, the bending angle of the light strip is easily too small, i.e., less than 90 degrees. This can easily cause the chips on the light strip to detach from the pads, resulting in the light strip failing to light up. Furthermore, after the LED light strip is fully wound, tape is usually used to directly attach and fix the end of the LED light strip. Over time, the tape easily peels off, causing the LED light strip to unravel. Utility Model Content

[0003] The purpose of this invention is to provide a reel for winding LED flexible light strips, so as to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution:

[0005] A reel for winding LED flexible light strips includes a first limiting disc, a second limiting disc, and a winding section. Both the first and second limiting discs are circular. The winding section is located between the first and second limiting discs, with the first limiting disc at the front end and the second limiting disc at the rear end. The winding section is a cylindrical structure extending from front to back and has a receiving cavity inside. The first, second, and winding discs are coaxially arranged, forming a storage slot for storing the light strip. The second limiting disc covers the rear end face of the winding section. A positioning through hole is provided at the axial center of the second limiting disc for mounting to the shaft of a winding machine. The positioning through hole communicates with the receiving cavity of the winding section. The winding section has several mounting through holes along its axial direction for the light strip to pass through. These mounting through holes communicate with both the receiving cavity and the storage slot.

[0006] The first limiting plate has several limiting through holes evenly distributed circumferentially along its axial direction for the cables at the tail end of the LED light strip to pass through, and the limiting through holes extend through both the front and rear ends of the first limiting plate.

[0007] The first limiting plate has a first locking through hole, and the second limiting plate has a second locking through hole, and the first locking through hole and the second locking through hole communicate with each other.

[0008] The first limiting plate has at least two first windows evenly distributed along the circumference of the axis for observing the remaining amount of light strip in the storage slot. The second limiting plate has a corresponding second window that corresponds to the position of the first window. The area of ​​the second window is smaller than the area of ​​the first window.

[0009] The first limiting plate, the second limiting plate, and the winding section are integrally injection molded.

[0010] Compared with the prior art, the reel for winding LED flexible light strips in this application eliminates the positioning plate structure inside the winding section. Instead, a second limiting plate covers the rear end face of the winding section, and positioning through holes are made on the second limiting plate. The through-type receiving cavity inside the winding section makes the insertion path of the light strip tail more direct and smooth, without the need for complex adjustments. This allows the bending angle of the light strip after insertion into the winding section to be greater than 90 degrees, effectively preventing defects such as chip detachment from the solder pad and ensuring the production quality of the light strip. In addition, a limiting through hole for fixing the tail end of the light strip is provided on the first limiting plate. The tail end of the light strip can be passed through the limiting through hole and tied, which can effectively prevent the light strip from loosening during production and transportation, reduce the risk of dead lights, and improve the appearance of the reel.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Specific Implementation Example 1: Please refer to Figures 1 to 4 In this embodiment of the utility model, a reel for winding LED flexible light strips includes a first limiting reel 1, a second limiting reel 2, and a winding part 3, wherein the first limiting reel 1, the second limiting reel 2, and the winding part 3 are integrally injection molded.

[0017] The first limiting disc 1 and the second limiting disc 2 are both disc structures. The winding part 3 is located between the first limiting disc 1 and the second limiting disc 2. The first limiting disc 1 is at the front end of the winding part 3, and the second limiting disc 2 is at the rear end of the winding part 3. The winding part 3 is a cylindrical structure that extends from front to back. The winding part 3 has a receiving cavity 301 inside. The first limiting disc 1, the second limiting disc 2, and the winding part 3 are coaxially arranged. The first limiting disc 1, the second limiting disc 2, and the winding part 3 together form a storage slot 4 for storing the light strip. The second limiting plate 2 covers the rear end face of the winding section 3. The second limiting plate 2 has a positioning through hole 201 at its axial position for mounting with the shaft of the winding machine. The positioning through hole 201 communicates with the receiving cavity 301 of the winding section 3. The first limiting plate 1 has a guide hole at its axial position that communicates with the receiving cavity 301 of the winding section 3. The winding section 3 has several mounting through holes 302 along its axial direction for the insertion of the light strip. The mounting through holes 302 communicate with the receiving cavity 301 and the storage slot 4.

[0018] The first limiting plate 1 has several limiting through holes 101 evenly distributed circumferentially along its axial direction for the cables at the tail end of the LED light strip to pass through. The limiting through holes 101 pass through both the front and rear ends of the first limiting plate 1. When the light strip is being wound up, the cables at the tail end of the light strip are inserted into the corresponding limiting through holes 101 for binding, which can securely wind up the light strip and the reel. The first limiting plate 1 has a first locking through hole 102, and the second limiting plate 2 has a second locking through hole 202. The first locking through hole 102 and the second locking through hole 202 are connected. In actual use, the first locking through hole 102 can be equivalent to the limiting through hole 101, that is, the first locking hole and the limiting through hole 101 overlap. After the light strip is wound up, cable ties or the like can be used to pass through the first locking hole and the second locking hole to fix and clamp the first limiting plate 1 and the second limiting plate 2 together, which can further prevent the light strip from falling off the reel.

[0019] At least two first windows 103 are evenly distributed along the circumference of the first limiting plate 1 for observing the remaining amount of light strip in the storage slot 4. In this embodiment, four first windows 103 with the same structure are opened on the first limiting plate 1. The second limiting plate 2 is provided with a second window 203 corresponding to the position of the first window 103. The area of ​​the second window 203 is smaller than the area of ​​the first window 103. The remaining amount of light strip in the storage slot 4 can be observed through the first window 103 and the second window 203.

[0020] Compared with the prior art, the reel for winding LED flexible light strips in this application eliminates the positioning plate structure inside the winding section. Instead, a second limiting plate covers the rear end face of the winding section, and positioning through holes are made on the second limiting plate. The through-type receiving cavity inside the winding section makes the insertion path of the light strip tail more direct and smooth, without the need for complex adjustments. This allows the bending angle of the light strip after insertion into the winding section to be greater than 90 degrees, effectively preventing defects such as chip detachment from the solder pad and ensuring the production quality of the light strip. In addition, a limiting through hole for fixing the tail end of the light strip is provided on the first limiting plate. The tail end of the light strip can be passed through the limiting through hole and tied, which can effectively prevent the light strip from loosening during production and transportation, reduce the risk of dead lights, and improve the appearance of the reel.
