Description

Technical Field

[0001] This utility model relates to the technical field of LED strip production equipment, and in particular to a frame-dropping and winding device. Background Technology

[0002] In the production of LED light strips, the extruded light strips need to be wound up, but existing winding devices have many technical defects. First, some devices suffer from unreasonable turntable structure design, leading to chaotic light strip placement and easy tangling during winding. Second, it is difficult to flexibly match the placement and winding speed of light strips of different specifications, resulting in low production efficiency. Third, it is impossible to illuminate and inspect the light strip quality in real time during winding, requiring an additional inspection process and increasing production costs.

[0003] Therefore, there is an urgent need to design a frame-wound device with a reasonable structure, complete functions, and flexible matching of winding speed to solve the problem of easy tangling of light strips in the existing technology. Utility Model Content

[0004] In view of this, the present invention provides a frame-dropping and winding device to solve the problem of easy tangling during the winding of LED strips in the prior art.

[0005] To solve the above-mentioned technical problems, one technical solution adopted by this utility model is to provide a frame winding device. The winding device includes a rotating frame, a power component, a speed controller, and a switch component. The rotating frame is located on top of the power component and connected to the power component. The switch component is electrically connected to the speed controller, and the speed controller is electrically connected to the power component. When the switch component is turned on, the speed controller receives a preset drive signal and drives the power component to rotate. The power component drives the rotating frame to rotate along a first preset direction or a second preset direction.

[0006] As an embodiment of this utility model, the switch assembly includes an automatic rotary switch, which is electrically connected to the speed controller. When the automatic rotary switch is turned on, the preset drive signal received by the speed controller is an automatic rotation signal, and the speed controller drives the power assembly to rotate the rotating frame along the first preset direction.

[0007] As an embodiment of this utility model, the frame winding device further includes a manual control component, which is electrically connected to the speed controller. The switch assembly includes a manual control switch. When the manual control switch is turned on, the automatic rotation switch is turned off. The preset drive signal received by the speed controller is a manual control signal. The speed controller drives the power assembly to rotate the rotating frame along the second preset direction.

[0008] In one embodiment of this utility model, the rotation speed of the rotating frame along the first preset direction is a first preset speed, which is controlled by the speed regulator; the rotation speed of the rotating frame along the second preset direction is a second preset speed, which is controlled by the manual control component.

[0009] As one embodiment of this utility model, the first preset direction is a clockwise direction or a counterclockwise direction, and the second preset direction is opposite to the first preset direction.

[0010] In one embodiment of this utility model, the power assembly includes a base and a motor. The rotating frame is located on the top of the base, and the motor is located inside the base. The output end of the motor extends out from the top of the base and is connected to the rotating frame. The motor is electrically connected to the speed controller, which drives the motor to rotate, and the motor drives the rotating frame to rotate.

[0011] As an embodiment of this utility model, the frame-dropping and winding device further includes a test line, which is disposed in the rotating frame. One end of the test line is used to detect the lit LED strip, and the other end of the test line is used to connect to the test circuit.

[0012] As an embodiment of the present invention, the frame winding device further includes a hollow test shaft, which is vertically connected to the bottom of the rotating frame and located at the center of the rotation axis of the rotating frame. The interior of the test shaft is used to accommodate the test wire passing through.

[0013] In one embodiment of this utility model, the rotating frame is a cylinder with a preset diameter and a preset height.

[0014] As an embodiment of this utility model, the switch assembly further includes an emergency stop switch, which is electrically connected to the speed controller and the motor respectively. The emergency stop switch is used to cut off the power supply to the speed controller and the motor so as to stop the rotating frame from rotating.

[0015] Compared with the prior art, the frame-feeding and winding device provided in this embodiment of the utility model has the following advantages:

[0016] 1. In the frame-winding device provided by this utility model, a rotating frame is connected to the power component and placed on top of it. The switch component is electrically connected to the speed controller, and the speed controller is electrically connected to the power component. When the switch component is turned on, the speed controller receives a preset drive signal and drives the power component to rotate, thereby driving the rotating frame to rotate in the first or second preset direction. By receiving the preset drive signal, bidirectional rotation control is achieved to adjust the winding direction, avoiding tension concentration. This solves the problem in the prior art where the light strip is easily knotted and tangled during the winding process due to unidirectional rotation.

[0017] 2. The frame-dropping and winding device provided by this utility model is equipped with an automatic rotation switch electrically connected to a speed controller. When the automatic rotation switch is turned on, the speed controller receives the automatic rotation signal and drives the power component to rotate the rotating frame along the first preset direction, which can realize automatic and stable frame drop, ensuring that the light strip drops into the frame in an orderly manner along a fixed trajectory, and solving the problems of uneven frame drop and easy stacking of light strips.

[0018] 3. The frame winding device provided by this utility model is equipped with a manual control component electrically connected to the speed controller. The switch assembly includes a manual control switch. When the manual control switch is turned on, the automatic rotation switch is automatically turned off. The speed controller receives the manual control signal and drives the power component to rotate the rotating frame along the second preset direction. The manual control component switches to the reverse rotation of the second preset direction to realize winding or other special adjustments, solving the problem that the automatic rotation mode cannot meet the needs of temporary adjustments.

[0019] 4. In the frame dropping and winding device provided by this utility model, the rotation speed of the rotating frame along the first preset direction is set as the first preset speed and controlled by a speed regulator. The rotation speed of the rotating frame along the second preset direction is set as the second preset speed and controlled by a manual control component. This realizes the speed adjustment method of automatic rotation mode and manual mode, so that the frame dropping consistency is ensured in automatic rotation mode, and the adjustable speed in manual mode can meet diverse winding needs, solving the problem that a single speed cannot adapt to the frame dropping and winding requirements of different specifications of light strips.

[0020] 5. In the frame-winding device provided by this utility model, the first preset direction is set to be clockwise or counterclockwise, and the second preset direction is opposite to the first preset direction, forming a complete bidirectional rotation system, which solves the problem that the direction of traditional equipment is fixed and cannot eliminate the entanglement that has been generated by reverse operation.

[0021] 6. The frame-feeding and winding device provided by this utility model includes a power component comprising a base and a motor. The rotating frame is located on top of the base, and the motor is located inside the base with its output end extending from the top of the base and connected to the rotating frame. The motor is electrically connected to a speed controller, which drives the motor to rotate. The motor then drives the rotating frame to rotate. By integrating the motor internally, external interference is reduced. The direct connection of the motor's output end to the rotating frame results in higher transmission efficiency, reduced energy loss, and solves the problem of frequent failures caused by numerous transmission components.

[0022] 7. In the frame-dropping and winding equipment provided by this utility model, a test line is set in the rotating frame. One end is used to detect the lighting of the light strip, and the other end is used to connect to the test circuit to realize synchronous lighting detection during the winding process. By detecting the quality of the light strip in real time, the lag of traditional offline detection is avoided, and the problem of traditional equipment requiring separate detection after winding, which is inefficient and may miss defective products is solved.

[0023] 8. The frame-feeding and winding device provided by this utility model features a hollow test shaft, vertically connected to the bottom of the rotating frame and located at the center of the rotating frame's axis. The interior of the test shaft accommodates the test wires as they pass through. This hollow design prevents the wires from becoming tangled during rotation. Firstly, the test shaft's central location ensures the wires rotate synchronously with the shaft, eliminating the risk of tangling due to centrifugal force. Secondly, the internal space protects the test wires from external damage, extending their service life. This solves the problem of test wires easily rubbing and tangling with other components or LED strips during rotation, leading to short circuits or poor contact.

[0024] 9. In the frame-dropping and winding device provided by this utility model, the rotating frame is cylindrical, and its diameter and height are both preset lengths. It can adapt to various light strip sizes, provide sufficient space for dropping the light strip, avoid the light strip being squeezed and tangled due to insufficient space, and solve the problem that the traditional rotating frame size is unreasonable, resulting in large-size light strips not being able to drop completely into the frame or being over-stacked.

[0025] 10. In the frame winding device provided by this utility model, an emergency stop switch is provided and electrically connected to the speed controller and the motor respectively. It is used to cut off the power supply of the speed controller and the motor so that the rotating frame stops rotating. The power supply is quickly cut off by the emergency stop switch to prevent abnormal entanglement from spreading. It can not only ensure the reliability of power outage, but also avoid single point failure. It solves the problem that existing equipment may damage the light strip or even the equipment after entanglement occurs due to the lack of emergency braking function. Attached Figure Description

[0041] Example

[0042] Please see Figure 1 The present invention discloses a frame-dropping and winding device 1, which is used in conjunction with an extrusion furnace. The light strip falls from the extrusion furnace to the frame-dropping and winding device 1, and is formed into a finished roll after frame-dropping and winding.

[0043] Furthermore, please combine Figures 1 to 3 As shown, the frame winding device 1 includes a rotating frame 11, a power assembly 12, a speed regulator 13, and a switch assembly 14. The rotating frame 11 is located on top of the power assembly 12 and connected to the power assembly 12. The switch assembly 14 is electrically connected to the speed regulator 13, and the speed regulator 13 is electrically connected to the power assembly 12. When the switch assembly 14 is turned on, the speed regulator 13 receives a preset drive signal and drives the power assembly 12 to rotate. The power assembly 12 drives the rotating frame 11 to rotate along a first preset direction or a second preset direction.

[0044] It is understood that the rotating frame 11 is connected to the power component 12 and placed on top of it, the switch component 14 is electrically connected to the speed controller 13, and the speed controller 13 is electrically connected to the power component 12. When the switch component 14 is turned on, the speed controller 13 receives a preset drive signal and drives the power component 12 to rotate, thereby driving the rotating frame 11 to rotate in the first or second preset direction. By receiving the preset drive signal, bidirectional rotation control is achieved to adjust the winding direction, avoid tension concentration, and solve the problem in the prior art that the light strip is easy to knot and entangle during the winding process due to unidirectional rotation.

[0045] Further, see Figure 4 As shown, the rotating frame 11 is a cylinder with a preset diameter and a preset height.

[0046] Optionally, the preset length is 40-120cm, and the preset height is 20-60cm. In this embodiment of the utility model, see [reference needed]. Figure 5 and Figure 6 As shown, the preset length L is 80cm and the preset height H is 40cm, but these are not intended to limit the present invention. The rotating frame 11 is made of 304 stainless steel, which solves the problems that existing plastic frames may have, such as insecure installation and affect the normal operation of the rotating disk.

[0047] Specifically, the rotating frame 11 can adapt to various light strip sizes, providing sufficient space for the light strip to fall into the frame, avoiding the light strip from being squeezed and tangled due to insufficient space, and solving the problem that the traditional rotating frame 11 is not reasonably sized, resulting in large light strips not being able to fall into the frame completely or being over-stacked.

[0048] Furthermore, please combine Figure 2 and Figure 3As shown, the switch assembly 14 includes an automatic rotary switch 141, which is electrically connected to the speed controller 13. When the automatic rotary switch 141 is turned on, the preset drive signal received by the speed controller 13 is an automatic rotation signal, and the speed controller 13 drives the power assembly 12 to rotate the rotating frame 11 along the first preset direction.

[0049] Specifically, when the automatic rotary switch 141 is turned on, the automatic frame dropping mode is activated. The speed controller 13 switch causes the motor 122 to drive the rotating frame 11 to rotate continuously at a relatively stable speed according to the set parameters. This speed can be adjusted by the speed controller 13 switch to achieve automatic and stable frame dropping, ensuring that the light strip drops into the frame in an orderly manner along a fixed trajectory, thus solving the problems of uneven frame dropping and easy stacking of the light strip.

[0050] Furthermore, the frame winding device 1 also includes a manual control component 15, which is electrically connected to the speed controller 13. The switch assembly 14 includes a manual control switch 142. When the manual control switch 142 is turned on, the automatic rotation switch 141 is turned off. The preset drive signal received by the speed controller 13 is a manual control signal. The speed controller 13 drives the power assembly 12 to rotate the rotating frame 11 along the second preset direction.

[0051] Specifically, the manual control component 15 is a foot pedal. When the manual control switch 142 is turned on, the foot pedal electric mode is activated. Each time the operator steps on the foot pedal, the rotating frame 11 rotates at a certain angle or for a certain period of time, which facilitates precise control of the position of the rotating frame 11 and the placement and winding of the light strip.

[0052] Furthermore, the speed at which the rotating frame 11 rotates along the first preset direction is a first preset speed, which is controlled by the speed regulator 13; the speed at which the rotating frame 11 rotates along the second preset direction is a second preset speed, which is controlled by the manual control component 15.

[0053] Specifically, the rotation speed of the rotating frame 11 along the first preset direction is set as the first preset speed and controlled by the speed regulator 13. The rotation speed of the rotating frame 11 along the second preset direction is set as the second preset speed and controlled by the manual control component 15. This realizes the speed adjustment method of automatic rotation mode and manual mode, so that the frame dropping consistency is ensured in automatic rotation mode, and the adjustable speed in manual mode can meet the diverse winding needs, solving the problem that a single speed cannot adapt to the frame dropping and winding requirements of different specifications of light strips.

[0054] Furthermore, the first preset direction is either clockwise or counterclockwise, and the second preset direction is opposite to the first preset direction.

[0055] Specifically, the first preset direction is the frame dropping direction, and the second preset direction is the winding direction. The frame dropping direction and the winding direction are opposite, forming a complete bidirectional rotation system, which solves the problem that traditional equipment has a fixed direction and cannot eliminate the entanglement that has already occurred through reverse operation.

[0056] Furthermore, the power assembly 12 includes a base 121 and a motor 122. The rotating frame 11 is located on the top of the base 121, and the motor 122 is located inside the base 121. The output end of the motor 122 extends out from the top of the base 121 and is connected to the rotating frame 11. The motor 122 is electrically connected to the speed regulator 13, and the speed regulator 13 drives the motor 122 to rotate. The motor 122 drives the rotating frame 11 to rotate.

[0057] Specifically, by incorporating the motor 122 to reduce external interference, and by directly connecting the output end of the motor 122 to the rotating frame 11, the transmission efficiency is higher, energy loss is reduced, and the problem of frequent failures caused by multiple transmission components is solved.

[0058] More specifically, the base 121 is made of brown bakelite board.

[0059] Furthermore, please combine Figure 3 and Figure 4 As shown, the frame-dropping and winding device 1 also includes a test line 16, which is disposed in the rotating frame 11. One end of the test line 16 is used to detect the lit LED strip, and the other end of the test line 16 is used to connect to the test circuit.

[0060] Specifically, test line 16 is set in the rotating frame 11, with one end used to detect the lit LED strip and the other end used to connect to the test circuit, so as to realize synchronous lighting detection during the winding process. By detecting the quality of the LED strip in real time, the lag of traditional offline detection is avoided, and the problem of low efficiency and possible missed detection of defective products in traditional equipment that requires separate detection after winding is solved.

[0061] Furthermore, the frame winding device 1 also includes a hollow test shaft 17, which is vertically connected to the bottom of the rotating frame 11 and is located at the center of the rotation axis of the rotating frame 11. The interior of the test shaft 17 is used to accommodate the test line 16 passing through.

[0062] Specifically, the test wire 16 is housed in a hollow test shaft 17, preventing the wire from becoming tangled during rotation. On one hand, the test shaft 17 is located at the center of the rotating shaft, and the wire rotates synchronously with the shaft, eliminating the risk of tangling caused by centrifugal force. On the other hand, the space inside the shaft protects the test wire 16 from external damage, extending its service life. This solves the problem that the test wire 16 is prone to friction and tangling with other components or light strips during rotation, leading to short circuits or poor contact.

[0063] Furthermore, please combine Figure 2 and Figure 3 As shown, the switch assembly 14 also includes an emergency stop switch 143, which is electrically connected to the speed controller 13 and the motor 122 respectively. The emergency stop switch 143 is used to cut off the power supply to the speed controller 13 and the motor 122 so as to stop the rotation of the rotating frame 11.

[0064] Specifically, by quickly cutting off the power supply through the emergency stop switch 143, the abnormal entanglement can be prevented from escalating. This not only ensures the reliability of the power outage but also avoids single-point failures, solving the problem that existing equipment may damage the light strip or even the equipment after entanglement occurs due to the lack of emergency braking function.

[0065] For ease of understanding, the working process of the frame-feeding and winding device 1 is described in detail below. Specifically, please refer to the following: Figures 1 to 4 As shown, during the LED strip lowering operation, turn on the power switch and the automatic rotation switch 141. The lowering and winding device 1 starts the automatic rotation mode. The motor 122 drives the rotating frame 11 to rotate along the first preset direction. Observe the speed at which the LED strip falls from the extruder. Adjust the speed regulator 13 by turning the automatic rotation switch 141 to control the speed at which the motor 122 drives the rotating frame 11 to match the speed at which the LED strip falls. The LED strip automatically falls into the frame along the outer track of the rotating disk. If any abnormalities such as LED strip entanglement or abnormal noise from the rotating disk are found during the process, the device will take corrective action. In case of any issues, immediately press the emergency stop switch 143 to stop the machine and inspect it. During the LED strip winding operation, turn on the manual control switch 142 and turn off the automatic rotation switch 141. The frame winding device 1 starts the foot pedal control mode. The motor 122 drives the rotating frame 11 to rotate in the second preset direction. By stepping on the foot pedal, the speed can be adjusted so that the speed of the rotating frame 11 matches the speed required for winding, so that the LED strip is neatly wound. During the winding process, the test line 16 is connected to the LED strip electrode. After the external power supply is applied, the LED strip lights up, and the quality of the LED strip can be detected in real time.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
