Description

Technical Field

[0001] This application relates to the field of marking device technology, specifically to a cable marking device. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus engraving intricate patterns, trademarks, and text.

[0003] Laser marking machines are needed when marking cables. However, most existing laser marking machines are placement-type devices that can only be placed on the factory floor to mark finished cables. They are also bulky and inconvenient to carry. They cannot mark cables that have already been installed in the outside world, so their application range is limited.

[0004] Patent CN113579485B discloses a portable marking machine, including a housing with a cover. The cover houses a galvanometer, a field lens connected to the galvanometer, and a worktable located below the field lens. A touchscreen is also mounted on the worktable. The housing is divided into a first cavity and a second cavity by a partition. The second cavity houses the main body, and both the main body and the galvanometer have USB interfaces. The worktable and galvanometer are connected to a base plate via support rods, and the base plate is connected to the cover plate to fix the worktable and galvanometer to the cover plate. The housing also has casters and a pull rod for moving the housing. In use, the cover is opened to allow the worktable and galvanometer to operate; closing the cover stores the worktable and galvanometer in the internal cavity of the housing, and then the housing is moved. This makes the device simple and convenient to move. However, it still has the following problems:

[0005] 1. Although it can be portable, it lacks a structure for accurate cable positioning, requiring manual support of the cable for marking, which is quite troublesome;

[0006] 2. This device requires manual movement of the cable to continuously perform marking operations; it cannot move the cable autonomously for automatic marking operations, resulting in a low level of automation.

[0007] 3. The inability to clean the surface of externally installed cables will affect the marking effect.

[0008] Therefore, this invention proposes a cable marking device. Summary of the Invention

[0009] The purpose of this application is to provide a cable marking device in order to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this application specifically adopts the following technical solution:

[0017] Furthermore, the sleeve includes two semi-ring plates that are movably inserted into the mounting ring groove, a rubber pad is connected between the two semi-ring plates, and semi-ring tubes that are fixedly connected to each other on both sides of the two semi-ring plates.

[0018] Furthermore, the opening and closing movable brush frame includes a positioning frame fixedly connected to two upper guide rods. Each end of the positioning frame is hinged with a half-frame. The half-frame is rotatably sleeved on the upper guide rod and fixedly connected to the lower guide rod. A through groove is constructed between the half-frame and the positioning frame, and a brush strip is connected in the through groove.

[0019] Furthermore, torsion springs are connected between the fixed seat and the flip seat, between the fixed plate and the mating plate, and between the positioning frame and the half frame. The bottoms of the two flip seats, the bottoms of the two mating plates, and the bottoms of the two half frames are detachably connected by buckles.

[0020] Furthermore, the rotary brush includes a rectangular frame, with inclined grooves at each of the four corners of the rectangular frame that fit onto the guide rod. A worm gear ring is rotatably installed inside the rectangular frame, and brush bristles are connected inside the worm gear ring. A worm gear meshing with the worm gear ring is rotatably installed on one side of the rectangular frame. A drive component for synchronously driving the worm gear and one of the universal joints is installed on the mating pulley seat.

[0021] Furthermore, the driving component includes a drive motor fixedly connected to one of the moving rods, the output shaft of the drive motor being connected to one of the universal joints, a transmission shaft being rotatably mounted on one side of the rectangular frame, the transmission shaft being connected to the worm gear via a bevel gear transmission, and the transmission shaft being connected to one of the universal joints via a belt and a pulley transmission.

[0022] Furthermore, each of the fixed rods is fixedly connected to a vertically arranged sliding rod, the upper end of which slides through the moving rod, and a tension spring sleeved on the sliding rod connects the fixed rod and the moving rod.

[0023] Furthermore, each of the two opposing fixed rods is equipped with an inclined column block. The adjusting roller includes a screw that moves through the inclined column block. A support wheel is rotatably mounted on one end of the screw. Two adjusting nuts that abut against both ends of the inclined column block are threaded onto the screw. The two opposing support wheels are arranged in an inverted V shape.

[0024] Furthermore, the pushing member includes a connecting shaft fixedly connected to the opposite sides of the two half-frames, a connecting rod hinged to the connecting shaft, a driving rod hinged to the other end of the connecting rod, and the other end of the driving rod fixedly connected to the end of the universal joint.

[0025] The beneficial effects of this application are as follows:

[0026] 1. This application connects the opening and closing base, the laser marking module, and two mating pulley seats together via a guide rod.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0040] like Figures 1-7 As shown, one embodiment of this application discloses a cable marking device, comprising:

[0041] The opening and closing base 1 has four rectangular guide rods 2 installed through it. The opening and closing base 1 is flipped back and forth along the two guide rods 2 located on the upper side. It should be noted that the bottom of the opening and closing base 1 is a movable end. When its movable ends are interlocked, it can form a ring frame shape, which is used for cables with small diameters to pass through, and facilitates the clamping and positioning of the cables.

[0042] The mating pulley seat 3 includes a fixed plate 301 fixedly connected to both ends of the two upper guide rods 2. Both ends of the fixed plate 301 are hinged to mating plates 302. The mating plates 302 are fixedly connected to the lower guide rod 2 and rotatably sleeved on the upper guide rod 2. A fixed rod 303 is fixedly connected to the bottom of each mating plate 302. Two adjusting rollers 304 are obliquely arranged on each of the four fixing rods 303, arranged in pairs opposite to each other. A movable rod 30 is vertically slidably mounted on the mating plate 302, parallel to the fixed rods 303. 5. A positioning roller 307 located between two adjusting rollers 304 is connected between the two moving rods 305 via a universal joint 306. It should be noted that a limiting angle is constructed between the upper end of the mating plate 302 and the end of the fixed plate 301 to limit the flipping angle of the mating plate 302. When the mating plates 302 are interlocked, they can form a ring frame shape, thereby forming a triangular structure between the two adjusting rollers 304 and one positioning roller 307, which facilitates the rolling clamping of the cable and makes it easier to limit the device on the cable.

[0043] The laser marking module 4 is fixedly connected to the two guide rods 2 on the upper side and is located between one of the mating pulley seats 3 and the opening and closing base 1. The laser marking module 4 adopts the output end of the existing micro laser marking machine and can be connected to a power wire or a battery for use.

[0044] The cleaning mechanism 5 includes a rotary brush 501 detachably connected between the opening and closing base 1 and the laser marking module 4. An opening and closing movable brush frame 502 is slidably sleeved on the guide rod 2 and disposed between the opening and closing base 1 and another mating pulley seat 3. A pusher 6 is provided between the opening and closing movable brush frame 502 and one of the universal joints 306 to drive the opening and closing movable brush frame 502 to reciprocate. It should be noted that the rotary brush 501 is used to rotate and rub the surface of the cable, while the opening and closing movable brush frame 502 cleans the surface of the cable along the length of the cable by being driven by the pusher 6. The dual cleaning improves the cleaning effect, thereby ensuring the clarity and accuracy of the cable marking.

[0045] This device has two configurations. The first configuration is for marking small-diameter cables. Specifically, the opening and closing base 1, the mating pulley seat 3, and the opening and closing movable brush frame 502 are all in a closed state. In this configuration, the opening and closing base 1, the mating pulley seat 3, the rotating brush 501, and the opening and closing movable brush frame 502 are all horizontally positioned by the guide rod 2, ensuring their internal openings are on the same axis. This facilitates the passage of small-diameter cables. Simultaneously, the adjusting roller 304 and the positioning roller 307 clamp and position the cable on both sides, allowing the laser marking module 4 to accurately mark it. The rotation of the positioning roller 307 can also drive the cable to move autonomously within the laser, enabling continuous marking over long distances. The second configuration is for marking large-diameter cables. Specifically, the opening and closing base 1, the mating pulley seat 3, and the opening and closing movable brush frame 502 are all in a back-to-back flipped-open state at their bottom movable ends. This causes the adjusting roller 304 on the mating plate 302 to flip accordingly, forming... Figure 3 The device is designed to clamp the upper half of a large-diameter cable, allowing it to move freely on the cable and continuously mark the cable surface over long distances. This increases the device's flexibility and applicability.

[0046] like Figures 4-5As shown, in some embodiments, the opening and closing base 1 includes a fixed base 101 fixedly connected to two upper guide rods 2. Both ends of the fixed base 101 are hinged to a flip base 102 with its other end abutting against each other. The flip base 102 is rotatably sleeved on the upper guide rod 2 and fixedly connected to the lower guide rod 2. A through hole 103 is constructed between the flip base 102 and the fixed base 101. A mounting annular groove 104 is constructed within the through hole 103. A sleeve 105 for threading a cable is detachably inserted into the mounting annular groove 104. The flip base 102, as a fixed end, forms a positioning standard with the two guide rods 2. When the device needs to... To change the configuration, the flip base 102 can be flipped upwards, and the two guide rods 2 on the lower side will also flip upwards to form an inverted V-shaped structure. At the same time, the mounting ring groove 104 will be opened, and the sleeve 105 can be disassembled to abut against the upper side of the cable, making it easier for the device to move on cables with different diameters. When the device is in the marking configuration for small-diameter cables, the bottoms of the two flip bases 102 are connected, and the through hole 103 formed between them can clamp the sleeve 105, making it easier for smaller diameter cables to pass through and be positioned to ensure the accuracy of marking.

[0047] like Figures 4-5 As shown, in some embodiments, the sleeve 105 includes two semi-ring plates 1051 movably inserted into the mounting ring groove 104. A rubber pad 1052 is connected between the two semi-ring plates 1051. Semi-ring tubes 1053 are fixedly connected to each other on both sides of the two semi-ring plates 1051. After the two semi-ring plates 1051 are joined together, they can form a ring. The rubber pad 1052 between them has elastic expansion and contraction capabilities, which can make the two semi-ring plates 1051 move closer or further apart, thereby clamping cables of different diameters, realizing the positioning of the cables, and ensuring marking accuracy.

[0048] like Figure 6As shown, in some embodiments, the opening and closing movable brush frame 502 includes a positioning frame 5021 fixedly connected to two upper guide rods 2. Half-frames 5022 are hinged to both ends of the positioning frame 5021. The half-frames 5022 are rotatably sleeved on the upper guide rod 2 and fixedly connected to the lower guide rod 2. A through groove 5023 is formed between the half-frames 5022 and the positioning frame 5021. A brush strip 5024 is connected within the through groove 5023. In the first configuration of the device, the two half-frames 5022 abut against each other to form the through groove 5023. The inner brush strip 5024 is rolled into a ring to wrap around the cable. When the device or cable moves, it can move relative to the cable to clean the cable and ensure the marking is clear. When the device is in the second state, the half-frames 5022 are far apart and form an inverted V-shape with the positioning frame 5021, which can cover the upper side of the larger diameter cable. When the device or cable moves, it can also move relative to the cable to clean the surface of the cable to be marked and ensure the marking is clear.

[0049] like Figures 1-6 As shown, in some embodiments, torsion springs 7 are connected between the fixed base 101 and the flip base 102, between the fixed plate 301 and the mating plate 302, and between the positioning frame 5021 and the half frame 5022. The bottoms of the two flip bases 102, the bottoms of the two mating plates 302, and the bottoms of the two half frames 5022 are detachably connected by flip buckles 8. By setting the torsion springs 7, the flip bases 102, the half frames 5022, and the mating plates 302 can always have a relative flipping tendency between each other, thereby clamping the cable and improving the stability of the device. The flip buckles 8 can prevent the cable from falling out easily when the device is in the first state, thereby increasing safety.

[0050] like Figure 9 As shown, in some embodiments, the rotary brush 501 includes a rectangular frame 5011. Each of the four corners of the rectangular frame 5011 has a slanted groove 5012 that fits onto the guide rod 2. A worm gear ring 5013 is rotatably installed inside the rectangular frame 5011, and brush bristles 5014 are connected inside the worm gear ring 5013. A worm 5015, meshing with the worm gear ring 5013, is rotatably installed on one side of the rectangular frame 5011. A drive component 9 is installed on the mating pulley seat 3 to synchronously drive the worm 5015 and one of the universal joints 306 to rotate. When the device is running, the drive component 9 can drive the universal joint 306 and the worm 5015 to rotate synchronously. The universal joint 306 drives the positioning roller 307 to rotate, while the worm 5015 drives the worm gear ring 5013 to rotate. This allows the cable to move autonomously while simultaneously rotating and cleaning the cable surface, improving the cleaning effect.

[0051] like Figure 3 and Figure 9As shown, in some embodiments, the driving component 9 includes a drive motor 901 fixedly connected to one of the moving rods 305. The output shaft of the drive motor 901 is connected to one of the universal joints 306. A transmission shaft 902 is rotatably mounted on one side of the rectangular frame 5011. The transmission shaft 902 is connected to the worm gear 5015 via a bevel gear transmission. The transmission shaft 902 is connected to one of the universal joints 306 via a belt and a pulley transmission. The drive motor 901 can drive the universal joint 306 to rotate, thereby driving the positioning roller 307 to rotate, thus enabling the positioning roller 307 to adjust... Roller 304 is used to push the cable, realizing automated long-distance marking operation of the cable and increasing the convenience of the device. At the same time, it can also drive the rotation of drive shaft 902, worm gear 5015 and worm wheel ring 5013 to automatically clean the surface of the cable and ensure the clarity of the marking. It should be noted that four inclined slots 5012 are set on the rectangular frame 5011 to facilitate its installation and disassembly. When the device is transformed into the second form, it needs to be removed to avoid obstructing the device from fastening the cable. At the same time, the belt and sleeve 105 used to drive the drive shaft 902 to rotate also need to be removed to ensure the normal operation of the device.

[0052] like Figures 7-8 As shown, in some embodiments, a vertically arranged slide rod 3031 is fixedly connected to the fixed rod 303, and the upper end of the slide rod 3031 slides through the moving rod 305. A tension spring 3032 sleeved on the slide rod 3031 is connected between the fixed rod 303 and the moving rod 305.

[0053] like Figure 8 As shown, in some embodiments, inclined blocks 3033 are constructed on both of the two opposing fixed rods 303. The adjusting roller 304 includes a screw 3034 that moves through the inclined block 3033. A support wheel 3035 is rotatably mounted on one end of the screw 3034. Two adjusting nuts 3036 that abut against both ends of the inclined block 3033 are threaded onto the screw 3034. The two opposing support wheels 3035 are arranged in an inverted V shape. By setting the inclined blocks 3033, the screw 3034 and the support wheels 3035 can be set at an inclined angle. In the first configuration, the distance between the two support wheels 3035 can be adjusted using the adjusting nuts 3036 to accommodate the insertion of cables of different sizes. When the device is in the second configuration, the extension length of the support wheels 3035 can be adjusted to increase the wrapping range of cables with different diameters and angles, thereby improving the installation stability of the device and ensuring stable movement and marking of the device.

[0054] like Figure 1As shown, in some embodiments, the pusher 6 includes a connecting shaft 601 fixedly connected to the opposite sides of the two half-frames 5022. A connecting rod 602 is hinged to the connecting shaft 601, and a drive rod 603 is hinged to the other end of the connecting rod 602. The other end of the drive rod 603 is fixedly connected to the end of the universal joint 306. When the device or cable moves, it will move relative to the positioning roller 307, thereby driving the universal joint 306 to rotate. This causes the universal joint 306 to drive the drive rod 603 to rotate, thereby generating a crank-slider motion with the connecting rod 602. This, in turn, causes the half-frames 5022 to slide back and forth on the guide rod 2, increasing the friction cleaning effect on the cable and ensuring the marking quality.

[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
