[0001] The invention relates to the technical field of winding devices, and in particular to a winding device for producing flexible light strips. Background Art

[0002] 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 is like a strip. Compared with traditional LED lights, it has the advantages of long service life (generally normal life is 80,000-100,000 hours), energy saving and green environmental protection, and has gradually emerged in various decoration industries. In the process of light strip production, a winding device is required to wind the light strip.

[0003] The Chinese patent document with authorization announcement number CN220114880U discloses the technical field of LED light strips, solves the technical problem that LED light strips are easily damaged during the process of winding and bundling, and particularly relates to an anti-damage bundling device for LED light strips, including a support seat, a damage-proof pulley assembly is installed on the support seat, and a bundling mechanism for winding the light strip is installed on the support seat, the pulley assembly includes two fixed pulleys rotatably connected to the support seat, a slide groove is opened on the inner wall of the support seat between the two fixed pulleys, a slider is slidably connected in the slide groove, and a movable pulley is rotatably connected to the slider, the bundling mechanism includes a reel for winding the light strip, a reel 1 is fixed at one end of the reel, a reel 2 is slidably connected at the other end of the reel, a limiting mechanism for fixing is installed on the reel 2, and a motor for driving the reel to rotate is installed on the support seat. In the patent, the LED light strip can be prevented from being excessively loosened or excessively pulled during the process of winding and bundling, so as to avoid damage and ensure product quality.

[0004] During use of the existing light strip winding device, the winding wheel is first installed on the rotating shaft, and then the wire at one end of the light strip is passed through the hollow hole of the winding wheel. Then the wire end is manually pinched, and then the rotating shaft is rotated to make the light strip wind around the winding wheel. This is inconvenient to operate during the initial winding, and the final wire end is located outside the winding wheel, which can easily cause damage to the wire end. Summary of the invention

[0005] The present invention provides a winding device for producing a flexible light strip, aiming to solve the problem in the related art that the winding device is inconvenient to operate during the initial winding, and the final thread end is located outside the winding wheel, which easily leads to thread end damage.

[0006] The cam is provided with a rotation point which is arranged on the top of the cam and is used to rotate the take-up wheel, the cam being used to rotate the take-up wheel in a rotation direction relative to the take-up wheel.

[0007] The effect is that when winding, the wire end of the light strip is placed on the winding wheel, and the winding wheel rotates with the hook rod, and the rotation of the hook rod causes the mounting seat to rotate together, so that the slider moves backward along the spiral protrusion, and at the same time the hook rod is abutted against the mounting seat, so that the hook rod is rotated to be in the same straight line as the slide rod, so that the hook rod presses the wire end, and finally the wire groove moves into the hollow hole, and the hook rod causes a part of the wire end to be pushed between the wire groove and the hollow hole, so that this part of the wire end forms a protrusion, and the end of the wire end is also located in the winding wheel, so that the wire end is fixed, and the fixing operation of the wire end is simplified in such a winding process, thereby improving the winding efficiency, and at the same time, the end of the wire end does not protrude from the winding wheel after winding.

[0008] Preferably, the control mechanism includes a cylindrical block fixedly mounted on the machine base and coaxial with the winding wheel, a spiral protrusion is arranged on the circumferential surface of the cylindrical block, the number of spiral turns of the spiral protrusion is less than one turn, and a slider adapted to the spiral protrusion is arranged at the rear end of the slide rod, and when the mounting seat is in the position closest to the rotating ring, the slider contacts the cylindrical block, which has the effect of controlling the sliding of the slide rod by the spiral protrusion, thereby automatically controlling the state of the hook rod when the winding wheel rotates.

[0009] Preferably, the end of the spiral protrusion away from the winding wheel is connected to a semi-annular protrusion, and a slope for lifting the slider is provided on the rear side of the end of the semi-annular protrusion. The effect is that when the hook rod moves to the rearmost end, the slider is separated from the cylindrical block through the slope, thereby separating the hook rod from the thread end.

[0010] Preferably, a pressing piece is installed above the mounting seat for making the mounting seat close to the rotating ring, and its effect is that the mounting seat is reset by the pressing piece before winding.

[0011] Preferably, a rotating shaft is installed at the driving end of the driving source, the cylindrical block is coaxially rotatably connected to the rotating shaft, and a driving head adapted to the center hole of the winding wheel is provided at the front end of the rotating shaft.

[0012] Preferably, the driving source is a motor.

[0013] Preferably, the slide rod and the hook rod are hinged via a pin, and a torsion spring is installed at the hinge to keep the hook rod and the slide rod perpendicular.

[0014] Preferably, the winding wheel is composed of a drum shaft and two retaining rings respectively arranged at both ends of the drum shaft, a fan-shaped hollow hole is opened on the retaining ring, and one end of the fan-shaped hole close to the drum shaft is flush with the outer circumferential surface of the drum shaft.

[0015] Preferably, the damping member includes a pin, which is mounted at the bottom of the mounting seat, and a slot matching the pin is provided on the rotating ring, the effect of which is that the pin and the slot ensure that the sliding block and the spiral protrusion will not move away from the rotating ring when they move against each other.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0017] First, install the take-up wheel on the driving head at the front end of the rotating shaft, start the electric push rod to make the push plate press the mounting seat downward, so that the mounting seat is attached to the rotating ring, and then put the wire end of the light strip on the take-up wheel. The rotating shaft rotates to make the take-up wheel rotate with the hook rod, and the rotation of the hook rod causes the mounting seat to rotate together, so that the slider moves backward along the spiral protrusion, and the hook rod rotates to be in the same straight line with the slide rod, so that the hook rod presses the wire end, and finally the wire groove moves into the hollow hole, and the hook rod causes a part of the wire end to be pushed between the wire groove and the hollow hole, so that this part of the wire end forms a convex The end of the wire is still located inside the winding wheel, thereby fixing the wire end. When the slider moves to the semi-annular protrusion, the light strip has been wound around once, and the inclined surface at the end of the semi-annular protrusion lifts the slider, so that the mounting seat is away from the rotating ring by a certain distance, thereby making the slider detach from the annular protrusion, so that the hook rod no longer hooks the protruding part of the wire end. Such a winding process simplifies the fixing operation of the wire end, thereby improving the winding efficiency. At the same time, after winding, the end of the wire end does not protrude from the winding wheel, thereby avoiding the problem that the end of the wire end is easily damaged outside.

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, a winding device for producing flexible light strips includes a winding wheel 1, a machine base 2, a fixing component installed on the machine base 2 for fixing the thread end, and a driving source 3 (preferably a motor) for driving the winding wheel 1 to rotate. When winding, the thread end is fixed on the winding wheel 1 through the fixing component, and then the driving source 3 is started to rotate the winding wheel 1, thereby winding.

[0029] like Figure 2 and Figure 4As shown, the winding wheel 1 consists of a winding shaft 11 and two retaining rings 12 respectively arranged on the front and rear sides of the winding shaft 11, and the two retaining rings 12 are provided with fan-shaped hollow holes, and the end of the fan-shaped hollow holes close to the winding shaft 11 is flush with the outer circumferential surface of the winding shaft 11, and a connecting ring 26 is fixedly arranged in the machine base 2, and the driving source 3 is installed on the rear side of the connecting ring 26. The driving end of the driving source 3 is installed with a rotating shaft 31, and the cylindrical block 251 is coaxially connected to the rotating shaft 31 for rotation. The front end of the rotating shaft 31 is provided with a driving head 32 adapted to the center hole of the winding shaft 11, and the center axis of the winding wheel 1 is sleeved on the driving head 32 at the front end of the rotating shaft 31, and then the driving source 3 makes the rotating shaft 31 rotate with the winding wheel 1.

[0030] like Figure 2-Figure 4 As shown, the fixing assembly includes a rotating ring 21, a mounting seat 22, a damping member 23, a counterweight 24, a sliding rod 221, a hook rod 222 and a control mechanism 25. The rotating ring 21 is rotatably mounted on the machine base 2 and is coaxial with the winding wheel 1. The bottom of the mounting seat 22 is fixedly connected with a guide rod. The top of the rotating ring 21 is provided with a guide hole adapted to the guide rod, so that the mounting seat 22 is slidably mounted on the rotating ring 21. The damping member 23 includes a pin, which is mounted on the side wall of the guide rod. A slot adapted to the pin is provided in the guide hole to prevent the rotating ring 21 from being tangled with the mounting seat 22. The mounting seat 22 is easily detached when they are attached, and the counterweight 24 is installed at the bottom end of the rotating ring 21, which is used to make the center of gravity of the fixed component biased toward one end of the counterweight 24, so that the mounting seat 22 is located above the rotating ring 21 in the initial state. The sliding rod 221 is installed in the mounting seat 22, and the front end of the sliding rod 221 is hinged to the hook rod 222 through a pin, and a torsion spring is installed between the two. A protrusion is provided at the front end of the hook rod 222, and a wire groove 2221 is opened on one side of the front end of the hook rod 222, and the horizontal depth of the wire groove 2221 is not greater than the wire end diameter of the flexible light strip.

[0031] In the initial state, the torsion spring is used to make the hook rod 222 and the slide rod 221 perpendicular (such as Figure 3 As shown in the figure, at this time, the hook rod 222 is located in the hollow hole on the side of the winding wheel 1. When the thread end is placed on the winding wheel 1, the winding wheel 1 rotates to press against the hook rod 222, thereby causing the hook rod 222 to rotate. At the same time, the control mechanism 25 causes the slide bar 221 to slide in the direction away from the winding wheel 1, and the hook rod 222 presses against the mounting seat 22, so that the hook rod 222 rotates to be in the same straight line as the slide bar 221, so that the hook rod 222 presses the thread end, and finally the wire groove 2221 moves into the hollow hole. The hook rod 222 causes a part of the thread end to be pushed between the wire groove 2221 and the hollow hole, so that this part of the thread end forms a bulge, and the end of the thread end is still located in the winding wheel 1, thereby fixing the thread end (as shown in the figure). Figure 5 and Figure 6 as shown).

[0032] like Figure 3-Figure 8As shown, the control mechanism 25 includes a cylindrical block 251, a spiral protrusion 252 and a semi-annular protrusion 254 fixedly mounted on the machine base 2 and coaxial with the winding wheel 1. The cylindrical block 251 is fixedly mounted on the front side of the connecting ring 26. The spiral protrusion 252 is arranged on the circumferential surface of the cylindrical block 251. The number of spiral turns of the spiral protrusion 252 is less than one turn. The semi-annular protrusion 254 is connected to the end of the spiral protrusion 252 away from the winding wheel 1. The rear side of the end of the annular protrusion is provided with an inclined surface 2541 for lifting the slider 253. The rear end of the slide rod 221 is provided with a slider 253 adapted to the spiral protrusion 252. When the mounting seat 22 is at the position closest to the rotating ring 21, the slider 253 contacts the cylindrical block 251. When the winding wheel 1 rotates against the hook rod 222, the slider 253 moves backward along the spiral protrusion 252, thereby causing the slide bar 221 to move backward. When the slider 253 moves to the semi-annular protrusion 254, the wire groove 2221 moves into the hollow hole, and the slider 253 moves to the inclined surface 2541 at the end of the annular protrusion, thereby lifting the slider 253 and making the mounting seat 22 away from the rotating ring 21 by a certain distance, thereby causing the slider 253 to detach from the annular protrusion, so that the hook rod 222 no longer hooks the protruding part of the thread end.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a pressing piece 4 is installed above the mounting seat 22 for making the mounting seat 22 close to the rotating ring 21. The pressing piece 4 includes an electric push rod installed in the machine base 2, and a push plate is installed at the telescopic end of the electric push rod. After the winding wheel 1 is installed on the driving head 32, the hook rod 222 is located in the hollow hole on the retaining ring 12. The electric push rod is started to make the push plate press the mounting seat 22 downward, so that the mounting seat 22 is in contact with the rotating ring 21, and the slider 253 is in contact with the cylindrical block 251.

[0034] Working principle: first install the winding wheel 1 on the driving head 32 at the front end of the rotating shaft 31. At this time, the hook rod 222 is located in the hollow hole on the side of the winding wheel 1. Start the electric push rod to make the push plate press the mounting seat 22 downward, so that the mounting seat 22 is attached to the rotating ring 21, and the slider 253 is in contact with the cylindrical block 251. Then, the wire end of the light strip is placed on the winding wheel 1, and the rotating shaft 31 rotates to make the winding wheel 1 rotate with the hook rod 222. The rotation of the hook rod 222 causes the mounting seat 22 to rotate together, so that the slider 253 moves backward along the spiral protrusion 252. At the same time, the hook rod 222 is against the mounting seat 22, so that the hook rod 222 rotates to be in the same straight line with the slide rod 221, so that the hook rod 222 presses the wire end, and finally the wire groove 2221 moves into the hollow hole, and the hook rod 222 causes a part of the wire end to be pushed to make the wire groove 2221 and the hollow hole The holes form a protrusion on this part of the thread end, and the end of the thread end is still located in the winding wheel 1, thereby fixing the thread end. When the slider 253 moves to the semi-annular protrusion 254, the light strip has been wound around once, and the inclined surface 2541 at the end of the semi-annular protrusion 254 lifts the slider 253, so that the mounting seat 22 is away from the rotating ring 21 by a certain distance, so that the slider 253 is separated from the annular protrusion, so that the hook rod 222 no longer hooks the protruding part of the thread end. After completing the winding, the winding wheel 1 can be directly removed, and then the hook rod 222 is pulled outward. The hook rod 222 is reset under the action of the torsion spring, so as to prepare for the next winding. In such a winding process, the fixing operation of the thread end is simplified, thereby improving the winding efficiency. At the same time, the end of the wire end after winding is not exposed outside the winding wheel 1, thereby avoiding the problem that the end of the wire end is easily damaged outside.

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
