Description

Technical Field

[0001] The present invention relates to the technical field of storage, and in particular to a wire take-up device. Background Art

[0002] Wire take-ups are widely used to store linear objects such as test lines and ropes. Wire take-ups usually include a reel and a drive motor. When winding, one end of the test line is fixed on the reel. The drive motor drives the reel to rotate and wind the test line onto the reel. After winding, the test line is removed from the reel to facilitate the subsequent secondary use of the test line.

[0003] However, after the existing wire take-up is completed, the rolled test wire is wound too tightly on the reel, making it extremely difficult to remove the test wire from the reel, requiring a lot of effort. During this process, the test wire is easily deformed or knotted, greatly increasing the difficulty and complexity of the wire removal operation; moreover, the existing wire take-up can only wind the test wire into a reel with a fixed diameter. When the winding diameter needs to be changed, the reel with a specific diameter that matches the test wire must be replaced. This operation is not only cumbersome, but also time-consuming and energy-consuming.

[0004] Therefore, there is an urgent need for a wire take-up device to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a wire take-up device that can change the winding diameter, is suitable for more types and specifications of test wires, improves the flexibility of the wire take-up device, and facilitates the removal of the rolled test wire from the wire take-up device after the winding is completed, thereby improving the winding efficiency.

[0038] This embodiment provides a wire take-up device, such as Figure 1-Figure 2As shown, the wire take-up device includes a shell 1, a movable plate 2, two rotating shafts 22, a first movable assembly (not shown), a winding assembly 3 and a wire clamp assembly 7. The movable plate 2 is arranged in the shell 1, and the two rotating shafts 22 are both slidably arranged on the movable plate 2 along the first direction. The first movable assembly is arranged on the movable plate 2. The first movable assembly is used to drive the two rotating shafts 22 to approach or move away from each other along the first direction. The winding assembly 3 includes a first driving motor (not shown), two synchronous wheels 31 and an elastic transmission belt 32. The two synchronous wheels 31 are respectively rotatably arranged on the two rotating shafts 22. The elastic transmission belt 32 is wound around the outer periphery of the two synchronous wheels 31 and is tensioned by the two synchronous wheels 31. The first driving motor is connected to one of the two synchronous wheels 31 for transmission. The wire clamp assembly 7 is arranged on the elastic transmission belt 32. One end of the test line can be clamped by the wire clamp assembly 7.

[0039] When the test line is stored, one end of the test line is fixed to the wire clamp assembly 7. At this time, the elastic transmission belt 32 is wound around the outer periphery of the synchronous wheel 31 of the two rotating shafts 22 and is in a tensioned state. The first drive motor is started, and the first drive motor drives a synchronous wheel 31 connected to it to start rotating. Since the two synchronous wheels 31 are connected by the elastic transmission belt 32, when one synchronous wheel 31 rotates, the other synchronous wheel 31 will also rotate synchronously. The elastic transmission belt 32 starts to move under the drive of the two synchronous wheels 31, and the wire clamp assembly 7 moves with the movement of the elastic transmission belt 32. During the movement, the wire clamp assembly 7 will drive the test line to be wound onto the elastic transmission belt 32. After the winding is completed, the first moving assembly starts to work to adjust the distance between the two rotating shafts 22 so that the two rotating shafts 22 are close to each other, which is convenient for removing the test line from the elastic transmission belt 32, avoiding deformation of the test line due to pulling the test line hard. The test line is more regular after being taken off the line, which is convenient for subsequent sorting, storage and reuse, thereby improving the work efficiency of storing the test line; in addition, the wire take-up device can change the winding diameter, which is suitable for more types and specifications of test lines, and improves the flexibility of the wire take-up device.

[0040] In this embodiment, the distance between the two rotating shafts 22 can be selected from a suitable storage length between 15cm and 40cm for operation. The specific length can be 15cm, 20cm, 25cm, 30cm, 35cm, or 40cm, which is not limited here.

[0041] In this embodiment, a slide rail 21 extending along the first direction is provided on the movable plate 2 corresponding to the rotating shaft 22. The rotating shaft 22 is slidably connected to the slide rail 21, so that the rotating shaft 22 can only slide on the slide rail 21 along the first direction, avoiding the deviation or shaking of the rotating shaft 22 in other directions, and improving the reliability of the operation of the wire take-up device. In this embodiment, two slide rails 21 are provided corresponding to the two rotating shafts 22, and the two rotating shafts 22 are slidably connected to the two slide rails 21 respectively. In some embodiments, a slide rail 21 extending along the first direction is provided on the movable plate 2, and the two rotating shafts 22 are slidably connected to the same slide rail 21. The setting of the slide rail 21 is not specifically limited here, and it is sufficient that the rotating shaft 22 can stably slide along the first direction.

[0042] like Figure 1-Figure 2 As shown, the wire take-up device also includes a limit assembly 4, which is arranged at the end of the rotating shaft 22 away from the movable plate 2. The limit assembly 4 is used to limit the test line to the elastic transmission belt 32, or allow the test line to fall off the elastic transmission belt 32. During the winding process, the limit assembly 4 and the movable plate 2 cooperate to ensure that the test line is always stably located on the elastic transmission belt 32, and can effectively prevent the test line from deviating from the winding trajectory, so that the test line can be neatly wound on the elastic transmission belt 32; when the winding is completed and the test line needs to be removed, the limit assembly 4 switches to a state that allows the test line to fall off the elastic transmission belt 32. The operator does not need to laboriously pull the test line out of the elastic transmission belt 32, thereby improving the working efficiency of the wire take-up device in storing the test line.

[0043] like Figure 1-Figure 2 As shown, the limiting assembly 4 includes a flip drive (not shown) and at least one limiting flap 41. The limiting flap 41 is rotatably arranged on the end surface of the rotating shaft 22 away from the movable plate 2. The flip drive is used to drive the limiting flap 41 to rotate so that at least part of the limiting flap 41 protrudes from the rotating shaft 22 in the radial direction of the rotating shaft 22. On the one hand, the space at the end of the rotating shaft 22 is fully utilized without occupying too much space inside the wire take-up device, making the overall structure of the wire take-up device more compact, which is conducive to the miniaturization and lightweight design of the wire take-up device. On the other hand, the simple structure improves the overall reliability and service life of the wire take-up device.

[0044] In this embodiment, Figure 1-Figure 2As shown, the limiting assembly 4 includes two limiting flaps 41, which are arranged at intervals along the second direction on the end face of the rotating shaft 22 away from the movable plate 2. The two limiting flaps 41 are both connected to the output end of the flip drive, and the flip drive is used to drive the two limiting flaps 41 to flip synchronously. On the one hand, the two limiting flaps 41 arranged at intervals along the second direction can limit the test line from different positions, improve the stability and reliability of the test line winding process, and prevent the test line from sliding or deflecting laterally on the elastic transmission belt 32; on the other hand, the two limiting flaps 41 are directly connected to the end face of the rotating shaft 22, and the structure is relatively compact. It can effectively limit the test line without taking up too much space, which is conducive to the overall miniaturization design of the wire take-up. In other embodiments, the limiting assembly 4 can include three, four, etc., which are not specifically limited here.

[0045] In some embodiments, the flipping drive component can be an electromagnetic drive component, and an electromagnet is provided at the center of the end of the rotating shaft 22. When the electromagnetic drive component is turned on, the electromagnet is energized to generate a magnetic field. This magnetic field will attract or repel the two limit flaps 41, causing the two limit flaps 41 to flip synchronously. The flipping angle of the two limit flaps 41 can be changed by changing the amount of power applied to the electromagnet.

[0046] In other embodiments, the flip driving component can drive the two limit flaps 41 to flip by a gear-rack drive. In this case, the flip driving component includes a cylinder, two gears and two racks. The piston rod in the cylinder is connected to the two racks, and the two racks are respectively engaged with the two gears. The two gears are respectively connected to the two limit flaps 41. The piston rod moves back and forth in the cylinder, driving the two racks to move, and then the two gears rotate and drive the two limit flaps 41 to flip.

[0047] Specifically, when the wire take-up device winds up the test line, the limit flap 41 flips over to form a preset angle with the second direction. At this time, the limit flap 41 and the movable plate 2 are respectively located on both sides of the rotating shaft 22. The limit flap 41 and the movable plate 2 cooperate to limit the test line to the elastic transmission belt 32. When the test line is wound, the limit flap 41 flips over to be parallel to the third direction, which can support the test line and allow the test line to fall off the elastic transmission belt 32. The structure is ingenious, with fewer components, and the flexibility of the wire take-up device is improved. In other embodiments, the limit flap 41 can also flip 180 degrees and fit the end of the rotating shaft 22, allowing the limit flap 41 to allow the test line to fall off the elastic transmission belt 32.

[0048] In this embodiment, the first moving component includes a second drive motor (not shown), a first gear (not shown) and two first racks (not shown). The two first racks are arranged on the moving plate 2 in parallel with each other along the first direction. The first gear is clamped between the two first racks. The first gear is transmission-connected to the output end of the second drive motor. The two first racks are respectively engaged with the first gear. A rotating shaft 22 is fixed on each first rack, and a synchronous wheel 31 is rotatably provided on each rotating shaft 22. On the one hand, the second drive motor can drive the first gear to rotate and convert the rotation into linear motion of the two first racks, so that the two rotating shafts 22 are close to or away from each other. By precisely controlling the rotation angle of the second drive motor, fine position adjustment is achieved, thereby ensuring that the test line can be wound under appropriate width, spacing and other conditions, thereby improving the working quality of the wire take-up device; on the other hand, when the second drive motor drives the first gear to rotate, the two first racks will approach or move away from each other, that is, the two rotating shafts 22 fixed on the two first racks can approach or move away from each other synchronously and equidistantly, ensuring that the relative position relationship between the two synchronous wheels 31 always remains symmetrical and precise, thereby ensuring the stability of the overall structure and function of the wire take-up device.

[0049] In some embodiments, the first moving component may further include a stepper motor, a lead screw and two nuts. The lead screw is arranged along the first direction and is connected to the output end of the stepper motor. The two nuts are sleeved on the lead screw and threadedly connected to the lead screw. A rotating shaft 22 is fixed on each nut, and a synchronous wheel 31 is rotatably arranged on each rotating shaft 22. When the stepper motor drives the lead screw to rotate, the two nuts will approach or move away from each other, that is, the rotating shafts 22 fixed on the two nuts can approach or move away from each other synchronously and equidistantly.

[0050] like Figure 1-Figure 2 As shown, the wire take-up device also includes a second moving component (not shown) and a wire-pushing platform 5. The moving plate 2 is arranged on the output end of the second moving component. The second moving component is used to drive the moving plate 2 to move along the third direction. The wire-pushing platform 5 is fixed in the housing 1. When the second moving component drives the moving plate 2 to move along the third direction, the wire-pushing platform 5 can abut against the test line on the elastic transmission belt 32 and push the test line off the elastic transmission belt 32. Compared with the operator directly pulling the test line to separate the test line from the elastic transmission belt 32, the wire-pushing platform 5 pushes the test line off the elastic transmission belt 32 in a relatively gentle and stable manner, effectively avoiding damage or deformation of the test line due to improper force of the operator, and the various components have strong synergy, which improves the overall performance and reliability of the wire take-up device.

[0051] In this embodiment, the wire take-up device includes four wire top platforms 5, wherein two wire top platforms 5 are fixed on the top wall of the shell 1, and the two wire top platforms 5 are symmetrically arranged with respect to the second direction, and the other two wire top platforms 5 are fixed on the bottom wall of the shell 1, and the other two wire top platforms 5 are also symmetrically arranged with respect to the second direction, so that when the test line is pushed to leave the elastic transmission belt 32, the pushing force distribution is more uniform, and the test line will not be stuck or damaged due to excessive force on one side of the test line or unbalanced force, thereby improving the rationality and reliability of the overall structure of the wire take-up device.

[0052] In this embodiment, the second moving assembly includes a third drive motor (not shown), a second gear (not shown), and a second rack (not shown). The second rack is slidably mounted on the housing 1 along the third direction. The second rack is connected to the moving plate 2. The output end of the third drive motor is transmission-connected to the second gear, and the second gear meshes with the second rack. The rotational motion of the third drive motor is converted into linear motion of the second rack through the meshing of the second gear and the second rack. The transmission is stable and reliable, ensuring that the moving plate 2 moves smoothly along the third direction at a preset speed and trajectory, thereby improving the reliability of the wire take-up device.

[0053] In some embodiments, the second moving assembly may further include a cylinder having a piston rod capable of reciprocating along a third direction, the piston rod of the cylinder being connected to the moving plate 2, and the piston rod of the cylinder capable of pushing the moving plate 2 for linear motion along the third direction. The structure of the second moving assembly is not specifically limited herein, and only requires that it ensures that the moving plate 2 moves smoothly along the third direction at a predetermined speed and trajectory.

[0054] like Figure 1-Figure 2 As shown, the wire take-up device also includes a sensor 9. A wire hole 8 is also provided on the shell 1. The sensor 9 is used to monitor the test line at the wire hole 8, and can guide the test lines to enter the shell 1 along the same wire hole 8 to avoid crossing between the test lines, thereby improving the neatness and regularity of the wire taking-up, and thus improving the wire taking-up quality. The sensor 9 monitors the entry of the test line at the wire hole 8, and can detect and deal with abnormal situations in time, thereby improving the reliability of the wire take-up device.

[0055] In some embodiments, the sensor 9 is a photoelectric sensor that can determine the incoming wire situation at the wire hole 8. When the test wire is wound, the operator can know in time, which facilitates the offline work. In other embodiments, the sensor 9 is a speed sensor. According to the real-time speed of the test wire passing through the wire hole 8 fed back by the speed sensor, the rotation speed of the elastic transmission belt 32 is adjusted in time. In addition, it can also determine whether the winding process is smooth based on the real-time speed of the test wire passing through the wire hole 8. When the winding speed slows down, the operator can adaptively reduce the rotation speed of the elastic transmission belt 32 to avoid damage to the test wire or damage to the wire take-up parts, thereby improving the reliability of the wire take-up. The type of sensor 9 can be selected according to actual conditions and is not specifically limited here.

[0056] In this embodiment, the wire clamp assembly 7 includes a clamping cylinder and two clamping arms. The clamping cylinder is arranged on the elastic transmission belt 32. The two clamping arms are respectively connected to the two output ends of the clamping cylinder. The two clamping arms can apply sufficient clamping force to the test line, and by adjusting the air pressure in the clamping cylinder, the strength of the clamping force can be conveniently controlled to adapt to the clamping requirements of the test line under different types and working conditions.

[0057] In this embodiment, the wire reel also includes a cover plate, and an opening is provided on the shell 1. The cover plate is hinged to the shell 1 and can close or open the opening. On the one hand, the cover plate is an effective barrier relative to the shell 1, preventing dust, hair, debris and other external debris from entering the interior of the wire reel, ensuring the cleanliness of the internal environment of the wire reel and extending the service life of various components in the wire reel; on the other hand, when the test line is in the winding process, closing the opening can prevent the operator from putting his hands or other objects into the interior of the wire reel, avoiding accidental injury to the operator, and improving the safety and reliability of the wire reel.

[0058] In some embodiments, the cover is a transparent cover, which facilitates the operator to observe the winding condition of the test line in real time. When the test line has a winding failure, the operator can quickly take corresponding measures to suspend the operation of the wire reel to ensure the reliability of the wire reel.

[0059] like Figure 1-Figure 2 As shown, the wire take-up device also includes a wire binding assembly 6, which can be a rotary hook type knotting actuator, a robotic arm type knotting actuator, a pneumatic type knotting actuator, etc. The wire binding assembly 6 is a relatively common technical means in this field and will not be described here. Of course, the operator can also manually use paper tape, adhesive tape or cable ties to bind the test line.

[0060] In summary, the specific operation process of the wire take-up device is as follows:

[0061] (1) Pass the test wire through the wire hole 8 and clamp the test wire with the wire clamp assembly 7;

[0062] (2) Turn on the second drive motor and adjust the distance between the two synchronous wheels 31 to determine the winding width of the test line;

[0063] (3) The flip driving member drives the two limit flaps 41 to flip, and the limit flaps 41 form a preset angle with the second direction, limiting the position of the test line on the elastic transmission belt 32;

[0064] (4) Turn on the first drive motor to drive the elastic transmission belt 32 to move, so that the test line is wound around the elastic transmission belt 32;

[0065] (5) When the test line is wound, the second drive motor is turned on, the two synchronous wheels 31 are adjusted to move closer to each other, and the flip drive member drives the limit flap 41 to flip, and the limit flap 41 is parallel to the third direction;

[0066] (6) Turn on the third drive motor to drive the movable plate 2 to move along the third direction, so that the top line platform 5 abuts against the test line on the elastic transmission belt 32, and pushes the test line from the elastic transmission belt 32 to the limit flap 41;

[0067] (7) Open the wire binding assembly 6 and bind the test wire on the limit flap 41;

[0068] (8) The wire clamp assembly 7 releases the test wire, the movable plate 2 continues to move in the third direction, and the wire lifting platform 5 pushes the test wire off the limit flap 41, completing the entire winding and unwinding process. The various components of the wire take-up device cooperate with each other to facilitate the removal of the test wire after winding, improve the working efficiency of the wire take-up device, and reduce the errors and inconveniences that may be caused by manual operation.

[0069] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
