Description

Technical Field

[0001] This invention relates to the field of coloring equipment, and more particularly to an automated coloring ring device for a cylindrical shaft. Background Technology

[0002] In the production of electronic components, motor rotors, shaft parts, etc., it is often necessary to apply color rings to the ends or specific positions of cylindrical shaft parts to distinguish specifications, polarity or phase. One type of cylindrical shaft has an annular protrusion in the middle section, one end is cylindrical and the other end is rod-shaped. During processing, different positions on the cylindrical end need to be colored.

[0003] Traditional color-coating ring methods often involve manual hand-held application of color onto a rotating coating wheel, resulting in low efficiency, inaccurate coating positions, inconsistent color ring widths, and significant paint waste. Furthermore, manual operation makes it difficult to guarantee consistent coating quality across each cylinder, failing to meet the demands of mass production. Therefore, an automated color-coating ring system for cylinders is needed. Summary of the Invention

[0004] The purpose of this invention is to provide an automated color-coating ring device for cylindrical shafts, thereby solving the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated color-coating ring device for cylindrical shafts, comprising a frame, on which an electric turntable and a vibrating feeder are fixedly connected. Multiple follower carriers are fixedly connected to the rotating end of the electric turntable. Each follower carrier includes a bearing seat, a follower wheel, a collet, a pusher rod, a spring, and a baffle. The bearing seat is fixedly connected to the rotating end of the electric turntable, the follower wheel is rotatably connected to the bearing seat, the collet is fixedly connected to the follower wheel, and the pusher rod is slidably connected to the follower wheel and the collet. The follower wheel, collet, and pusher rod are coaxially arranged. The spring is located between the pusher rod and the follower wheel. The baffle is fixedly connected to the bearing seat, and one end of the pusher rod abuts against the baffle. Cylindrical shafts are sequentially arranged around the electric turntable on the frame. The system includes a loading robot, a positioning and pushing mechanism, a coloring ring mechanism, a unloading robot, and a discharge detection mechanism. A loading mechanism and a discharge cylinder are fixedly connected to the frame next to the unloading robot. The coloring ring mechanism includes a coloring bracket, a lifting cylinder, a lifting platform, a coloring wheel, a pigment tank, a first drive motor, a first friction drive wheel, a second drive motor, and a second friction drive wheel. The coloring bracket is fixedly connected to the frame. The lifting cylinder, pigment tank, first drive motor, and second drive motor are all fixedly connected to the coloring bracket. The lifting platform is fixedly connected to the piston rod of the lifting cylinder. The coloring wheel is rotatably connected to the lifting platform. The first friction drive wheel is fixedly connected to the shaft of the first drive motor, and the second friction drive wheel is fixedly connected to the shaft of the second drive motor.

[0006] Furthermore, the collet has a slotted groove at one end for holding the cylinder shaft, and the inner ring of the collet has rounded corners.

[0007] Furthermore, the positioning and pushing mechanism includes a pushing cylinder fixedly connected to the frame and a push plate fixedly connected to the piston rod of the pushing cylinder.

[0008] Furthermore, there are multiple color-coating ring mechanisms, which are distributed in a circular array along the electric turntable.

[0009] Furthermore, the unloading detection mechanism includes a detection bracket fixedly connected to the frame, and a laser sensor is fixedly connected to the detection bracket.

[0010] Furthermore, the material loading mechanism includes a linear module fixedly connected to the frame, a positioning seat fixedly connected to the moving platform of the linear module, a material loading tray placed on the positioning seat, and a plurality of material dispensing holes opened on the material loading tray.

[0011] Furthermore, both the first friction drive wheel and the second friction drive wheel are rubber wheels.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] An electric turntable drives multiple follower carriers to rotate cyclically, sequentially passing through the feeding, pushing, coloring ring, unloading, and inspection stations, thus realizing an automated assembly line operation for the coloring rings on the cylinder shaft. A vibrating feeder, in conjunction with a cylinder shaft feeding robot, achieves automatic feeding, while an unloading robot, in conjunction with a loading mechanism, achieves automatic unloading, improving production efficiency.

[0014] The follower carrier adopts a combination structure of bearing housing, follower wheel, collet, pusher rod and spring. The collet is used to hold the cylinder shaft, and the follower wheel can rotate freely under external force, so that the cylinder shaft can be driven to rotate by the friction drive wheel when the color ring is applied, ensuring uniform color ring. The pusher rod can push the coated cylinder shaft out of the collet under the action of the spring, making it easy for the unloading robot to grasp. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Example:

[0027] like Figures 1-8As shown, the present invention proposes an automated coloring ring device for cylindrical shafts, comprising a frame 1. An electric turntable 2 and a vibratory feeder 10 are fixedly connected to the frame 1. The electric turntable 2 is driven by a servo motor or stepper motor in conjunction with a cam divider to achieve intermittent indexing rotation. The vibratory feeder 10 is used to arrange bulk cylindrical shaft parts into an orderly arrangement and output them one by one.

[0028] Multiple follower carriers 3 are fixedly connected to the rotating end of the electric turntable 2, and the follower carriers 3 are evenly distributed along the circumference of the electric turntable 2. Each follower carrier 3 includes a bearing seat 301, a follower wheel 302, a collet 303, a push rod 304, a spring 305, and a baffle 306. The bearing seat 301 is fixedly connected to the rotating end of the electric turntable 2, and the follower wheel 302 is rotatably connected to the bearing seat 301. The collet 303 is fixedly connected to the follower wheel 302, and the rotation of the follower wheel 302 drives the collet 303 to rotate synchronously. The end of the collet 303 used to clamp the cylindrical shaft has a slot, allowing the collet 303 to clamp the cylindrical shaft after insertion; the inner ring of the collet 303 has rounded corners to facilitate the insertion of the cylindrical shaft.

[0029] The push rod 304 is slidably connected to the follower wheel 302 and the collet 303, and the follower wheel 302, collet 303, and push rod 304 are coaxially arranged. The baffle 306 is fixedly connected to the bearing seat 301 and is located behind the push rod 304. One end of the push rod 304 abuts against the baffle 306, and the spring 305 is located between the push rod 304 and the follower wheel 302. In its natural state, the spring 305 pushes the push rod 304 towards the baffle 306, keeping the push rod 304 abutting against the baffle 306. When unloading is required, the external unloading cylinder 11 pushes the push rod 304 towards the baffle 306, causing the push rod 304 to move forward and push the cylinder shaft out of the collet 303; after the unloading cylinder 11 resets, the spring 305 pushes the push rod 304 back to its original position.

[0030] The frame 1 is arranged around the electric turntable 2, with a cylindrical loading robot 4, a positioning and pushing mechanism 5, a coloring ring mechanism 6, a unloading robot 7, and an unloading and detection mechanism 8 arranged in sequence. That is, the electric turntable 2 drives the follower carrier 3 to pass through the loading station, pushing station, coloring station, unloading station, and detection station in sequence.

[0031] The cylindrical shaft loading robot 4 is used to clamp the cylindrical shaft from the discharge port of the vibrating feeder 10 and move it horizontally into the collet 303 of the follower carrier 3.

[0032] The positioning and pushing mechanism 5 includes a pushing cylinder 501 fixedly connected to the frame 1 and a push plate 502 fixedly connected to the piston rod of the pushing cylinder 501. When the follower carrier 3 rotates to the pushing position, the pushing cylinder 501 extends, and the push plate 502 pushes the end of the cylinder shaft, so that the cylinder shaft is fully inserted into the collet 303 (at this time, the annular protrusion in the middle of the cylinder shaft abuts against the collet 303), ensuring accurate positioning during subsequent coloring ring application.

[0033] The coloring ring mechanism 6 is used to coat the surface of the cylindrical shaft with color. The coloring ring mechanism 6 includes a coloring bracket 601, a lifting cylinder 602, a lifting platform 603, a coloring wheel 604, a pigment tank 605, a first drive motor 606, a first friction drive wheel 607, a second drive motor 608, and a second friction drive wheel 609. The coloring bracket 601 is fixedly connected to the frame 1. The lifting cylinder 602, pigment tank 605, first drive motor 606, and second drive motor 608 are all fixedly connected to the coloring bracket 601. The lifting platform 603 is fixedly connected to the piston rod of the lifting cylinder 602, and the coloring wheel 604 is rotatably connected to the lifting platform 603. The pigment tank 605 contains paint, and the lower part of the coloring wheel 604 is immersed in the pigment tank 605. The first friction drive wheel 607 is fixedly connected to the shaft of the first drive motor 606, and the second friction drive wheel 609 is fixedly connected to the shaft of the second drive motor 608. Both the first friction drive wheel 607 and the second friction drive wheel 609 are rubber wheels to increase friction and reduce wear.

[0034] There are multiple color-coating ring mechanisms 6, which are arranged in a circular array along the electric turntable 2. When it is necessary to coat multiple color rings or color rings at different positions, the different color-coating ring mechanisms can complete the task sequentially.

[0035] The unloading robot 7 is used to remove the painted cylindrical shaft from the follower carrier 3. A loading mechanism 9 and an unloading cylinder 11 are fixedly connected to the frame 1 next to the unloading robot 7. When the piston rod of the unloading cylinder 11 extends, it pushes the push rod 304 in the follower carrier 3, pushing the cylindrical shaft out of the collet 303 a certain distance, so that the unloading robot 7 can pick up the unpainted part of the cylindrical shaft.

[0036] The material loading mechanism 9 includes a linear module 901 fixedly connected to the frame 1. A positioning seat 902 is fixedly connected to the moving platform of the linear module 901, and a material loading tray 903 is placed on the positioning seat 902. The material loading tray 903 has multiple discharge holes. The linear module 901 can drive the material loading tray 903 to move, so that the unloading robot 7 can sequentially put the cylinder shaft into different discharge holes.

[0037] The unloading detection mechanism 8 includes a detection bracket 801 fixedly connected to the frame 1, and a laser sensor 802 fixedly connected to the detection bracket 801. The laser sensor 802 faces the collet 303 of the follower carrier 3 and is used to detect whether the cylinder shaft has been successfully unloaded. If the cylinder shaft is still detected, the equipment alarms to prompt manual handling.

[0038] The working principle of this invention is as follows:

[0039] The vibratory feeder 10 pairs of cylindrical shafts are fed. The cylindrical shaft feeding robot 4 clamps the cylindrical shaft at the discharge end of the vibratory feeder and inserts it parallel to the collet 303 of the follower carrier 3. The cylindrical shaft is elastically clamped by the collet 303.

[0040] The electric turntable 2 rotates one station, sending the follower carrier 3 equipped with the cylinder shaft to the station of the positioning and pushing mechanism 5. The pushing cylinder 501 extends, and the push plate 502 pushes the end of the cylinder shaft, so that the cylinder shaft is fully inserted into the collet 303 (at this time, the annular protrusion in the middle of the cylinder shaft abuts against the collet 303), and then the pushing cylinder 501 resets.

[0041] The electric turntable 2 continues to rotate, sending the follower carrier 3 to the coloring ring mechanism 6 station. At the coloring station, the follower wheel 302 contacts the lower part of the second friction drive wheel 609. First, the first drive motor 606 drives the first friction drive wheel 607 to rotate. Since the coloring wheel 604 is currently in close contact with the first friction drive wheel 607, it will also rotate and pick up pigment in the pigment tank 605. Then, the first drive motor 606 stops rotating, the piston rod of the lifting cylinder 602 extends, the lifting platform 603 moves upward, and the coloring wheel 604 abuts against the side wall of the cylinder shaft. The second drive motor 608 drives the second friction drive wheel 609 to rotate, and the follower wheel 302 rotates due to friction, thereby driving the collet 303 and the cylinder shaft to rotate synchronously. During the rotation of the cylinder shaft, the coloring wheel 604 will rotate along with it, coating a uniform color ring on the surface of the cylinder shaft. After the coloring is completed, the lifting cylinder 602 resets, the coloring wheel 604 leaves the cylinder shaft, and the coloring action is completed.

[0042] After the coloring is completed, the electric turntable 2 delivers the follower carrier 3 to the unloading robot 7 station. The unloading cylinder 11 extends, pushing the push rod 304 to push the cylinder shaft out of the collet 303 a certain distance, exposing the uncolored part of the cylinder shaft in the collet 303. After the grippers of the unloading robot 7 pick up the cylinder shaft, the unloading cylinder 11 resets, and the spring 305 pushes the push rod 304 to reset. The unloading robot 7 then places the cylinder shaft into the discharge hole of the loading tray 903 of the loading mechanism 9, completing the unloading process.
