Description
Technical Field
[0001] This invention relates to the field of tooling equipment technology, and more specifically, to a fully automatic rubber band suction and sleeve device. Background Technology
[0002] The rubber band placement process involves first selecting a rubber band of suitable size and tension. During operation, use your thumb and forefinger to gently stretch the rubber band to form a stable loop. Then, precisely align the loop and smoothly slip it onto the target object. This allows for quick and easy organization and packaging of tangled rubber bands.
[0003] Currently, in common rubber band placement operations, the common method is to manually pick up the rubber band, then use your fingers to spread it open, and finally place the rubber band on the corresponding target object, or use a simple elastic clamp to spread the rubber band open for placement. The above methods not only require a certain amount of manpower, but also lead to low work efficiency due to human fatigue.
[0004] Therefore, in view of this, we have studied and improved the existing structure to provide a fully automatic rubber band suction and sleeve device, in order to achieve a more practical purpose. Summary of the Invention

[0006] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

The rubber band placement plate is fixed to the bottom of one side of the inside of the equipment housing, and the disc-shaped top seat is fixed to the top of one side of the inside of the equipment housing. A stepper motor is fixedly installed on the top of the rubber band placement plate. The output end of the stepper motor is connected to a robot arm mounting turntable through a coupling.

[0008] Furthermore, the rubber band placement plate has a semi-annular shell structure, and a waste detection sensor is fixedly installed at one end of the rubber band placement plate.
[0009] Furthermore, the disc-shaped top seat is located directly above the rubber band placement plate, and the central axes of the disc-shaped top seat and the rubber band placement plate are collinear. An irregular ring track is provided on the disc-shaped top seat. A sliding rod is fixedly installed at the bottom of the disc-shaped top seat. The middle part of the hydraulic manipulator slides freely along the sliding rod, and the top of the hydraulic manipulator slides freely along an irregular circular track.
[0010] Furthermore, the number of hydraulic manipulators is six, and the six hydraulic manipulators are evenly distributed in a ring at equal angles, and each hydraulic manipulator is equipped with a loading and unloading sensor.
[0011] Furthermore, the rubber band spreading assembly includes a movable plate, a fixed plate, and an independent hydraulic rod. A support shaft is fixedly installed at the bottom end of the fixed plate, and the bottom end of the support shaft is fixed to the top end of the electric turntable. The movable disc is movably mounted on the support shaft via bearings, and the independent hydraulic rod is fixed on the electric turntable, and the independent hydraulic rod drives the movable disc to swing back and forth at small angles in a cycle.
[0012] Furthermore, the fixed plate is located directly above the movable plate, the movable plate has a plurality of first arc-shaped slide rails, and the fixed plate has a plurality of second arc-shaped slide rails. Several sliding columns are installed between the movable plate and the fixed plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1:
[0020] Please see Figures 1-9 A fully automatic rubber band suction and sleeve device includes a device housing 1, the entire device is installed in the device housing 1, and the device specifically includes: Rubber band suction part 2: includes a rubber band placement plate 201 and a disc-shaped top seat 202. The rubber band placement plate 201 is fixed to the bottom of one side inside the equipment housing 1, and the disc-shaped top seat 202 is fixed to the top of one side inside the equipment housing 1. A stepper motor 203 is fixedly installed on the top of the rubber band placement plate 201. The output end of the stepper motor 203 is connected to the robot arm mounting turntable 204 through a coupling. A hydraulic robot arm 205 is installed on the robot arm mounting turntable 204. The rubber band placement plate 201 is located directly below the robot arm mounting turntable 204. Rubber band stretching and transfer part 3: includes electric turntable 301, which is installed in the middle of the inside of the equipment housing 1, and four sets of rubber band stretching components 302 are provided on the electric turntable 301. The four sets of rubber band stretching components 302 are evenly distributed in a ring at equal angles. Rubber band sleeve part 4: includes drag chain guide rail 401, drag chain guide rail 401 is fixed inside the other side of the equipment housing 1, and the movable part of drag chain guide rail 401 is equipped with lifting hydraulic rod 402. The output end of lifting hydraulic rod 402 is fixed with suspension bracket 403, and a three-cylinder group 404 is fixedly installed on suspension bracket 403. Example 2:
[0021] Based on the above embodiment 1, further description is provided.
[0022] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Specifically, the rubber band placement plate 201 has a semi-annular shell structure, and a waste detection sensor 2011 is fixedly installed at one end of the rubber band placement plate 201.
[0023] The rubber bands are placed in the semi-circular rubber band placement tray 201. When the robot arm mounting turntable 204 rotates, the hydraulic robot arm 205 can easily pick up the rubber bands. The semi-circular rubber band placement tray 201 can accommodate more rubber bands, reducing the frequency of rubber band feeding in the rubber band placement tray 201.
[0024] The waste detection sensor 2011 can detect whether the rubber band it picks up is waste. If it is waste, it is discarded; otherwise, the rubber band is placed on the rubber band spreading assembly 302.
[0025] Specifically, the disc-shaped top seat 202 is located directly above the rubber band placement plate 201, and the central axes of the disc-shaped top seat 202 and the rubber band placement plate 201 are collinear. An irregular ring track 2021 is provided on the disc-shaped top seat 202. A slide rod 2022 is fixedly installed at the bottom of the disc-shaped top seat 202. The middle part of the hydraulic manipulator 205 slides freely along the slide rod 2022, and the top of the hydraulic manipulator 205 slides freely along the irregular ring track 2021.
[0026] Stepper motor 203 controls the rotation of electric turntable 301, and slide bar 2022 rotates synchronously. By using slide bar 2022 to limit the hydraulic manipulator 205, the hydraulic manipulator 205 will rotate. At the same time, since the hydraulic manipulator 205 will slide along the irregular circular track 2021, it will be forced to move along slide bar 2022, thereby enabling the hydraulic manipulator 205 to pick up the rubber bands on the entire rubber band placement plate 201.
[0027] Specifically, there are six hydraulic manipulators 205, which are evenly distributed in a ring at equal angles, and each hydraulic manipulator 205 is equipped with a loading / unloading sensor.
[0028] The loading and unloading sensors include a loading sensor and an unloading sensor. When picking up a rubber band, the loading sensor receives a signal, the hydraulic robot 205 receives the signal, and controls it to pick up the material. When releasing the rubber band onto the electric turntable 301, the unloading sensor receives a signal, the hydraulic robot 205 receives the signal, and controls it to unload the material.
[0029] See Figure 3 , Figure 4 , Figure 8 Specifically, the rubber band stretching assembly 302 includes a movable plate 3021, a fixed plate 3022, and an independent hydraulic rod 3023. A support shaft 3024 is fixedly installed at the bottom end of the fixed plate 3022, and the bottom end of the support shaft 3024 is fixed to the top end of the electric turntable 301. The movable disc 3021 is movably mounted on the support shaft 3024 via bearings, and the independent hydraulic rod 3023 is fixed on the electric turntable 301. The independent hydraulic rod 3023 drives the movable disc 3021 to swing back and forth at small angles in a cycle.
[0030] The extension and retraction of the independent hydraulic rod 3023 is a small-amplitude swing, and the independent hydraulic rod 3023 is controlled in a one-to-one correspondence with the movable plate 3021.
[0031] Specifically, the fixed plate 3022 is located directly above the movable plate 3021. The movable plate 3021 has several first arc-shaped slide rails 30211, and the fixed plate 3022 has several second arc-shaped slide rails 30221. Several sliding columns 3025 are installed between the movable plate 3021 and the fixed plate 3022. The upper end of the sliding column 3025 slides along the second arc-shaped slide rail 30221, and the middle part of the sliding column 3025 slides along the first arc-shaped slide rail 30211.
[0032] Since the fixed plate 3022 cannot rotate automatically, while the movable plate 3021 can rotate autonomously, when the movable plate 3021 swings back and forth, it will force the slide column 3025 to unfold or retract along the arc direction of the second arc-shaped slide rail 30221.
[0033] Specifically, each independent hydraulic rod 3023 is fixedly equipped with a set of sensors, which respectively sense the position signal of the fixed plate 3022 and the extension / retraction signal of the independent hydraulic rod 3023.
[0034] The extension and retraction of the independent hydraulic rods 3023 can be controlled according to the position of the fixed plate 3022, which in turn controls the unfolding or retraction of several sliding columns 3025.
[0035] See Figure 3 , Figure 4 , Figure 9 Specifically, the bottom of the suspension bracket 403 is fixedly installed with six long tubes 4031, and each long tube 4031 is slidably connected to a thin column 4032. A three-cylinder group 404 controls the lifting and lowering of two thin columns 4032.
[0036] The three-cylinder group 404 works synchronously, thereby controlling the synchronous lifting and lowering of the thin column 4032. The three-cylinder group 404 ensures that the thin column 4032 has sufficient power when lifting and lowering.
[0037] Specifically, the six thin pillars 4032 form a regular hexagonal structure when fully slid out.
[0038] The regular hexagonal structure is smaller than the regular hexagonal structure when the six sliding pillars 3025 are fully extended. In this way, when the six sliding pillars 3025 are folded up, the rubber band can be transferred to the regular hexagon where the thin pillar 4032 is located.
[0039] Working principle: This fully automatic rubber band picking and placing equipment achieves fully automated operation from picking up the rubber band to placing it on the sleeve. Rubber band absorber part 2 working: A semi-circular rubber band stacking tray 201 is used to stack rubber bands to be processed. A stepper motor 203 drives the rotating robotic arm mounting turntable 204 to rotate. Six hydraulic robotic arms 205, evenly distributed on the turntable, move radially above the rubber band stacking tray 201 under the constraints of a sliding rod 2022 and an irregularly shaped circular track 2021. Controlled by loading and unloading sensors, the hydraulic robotic arms 205 precisely pick up the rubber bands and screen out unqualified products through a waste detection sensor 2011. Subsequently, the hydraulic robotic arms 205 transfer the qualified rubber bands to the top of the electric turntable 301, preparing for the subsequent unfolding process.
[0040] The rubber band stretching and transfer section consists of three parts: The electric turntable 301 drives four sets of ring-shaped rubber band spreading components 302 to rotate intermittently. In each set of rubber band spreading components 302, an independent hydraulic rod 3023 drives a movable disc 3021 to reciprocate at a small angle. Guided by the first arc-shaped slide rail 30211 and the second arc-shaped slide rail 30221, the sliding column 3025 radially expands or contracts between the fixed disc 3022 and the movable disc 3021, thereby spreading or releasing the rubber band. During this process, sensors monitor the position of the fixed disc 3022 and the state of the independent hydraulic rod 3023 in real time to ensure the synchronization and stability of the spreading action. After the rubber band is spread into a standard hexagon, the electric turntable 301 transfers it to the fitting station.
[0041] The rubber band sleeve part 4 works as follows: The cable chain guide 401 moves the suspended bracket 403 horizontally above the spreading assembly. The lifting hydraulic rod 402 adjusts the height of the bracket, aligning the six thin columns 4032 with the spread rubber band. The three-cylinder assembly 404 synchronously controls the thin columns 4032 to descend and insert into the inside of the rubber band. Subsequently, the rubber band spreading assembly 302 retracts the sliding column 3025, transferring the rubber band to the hexagonal frame formed by the thin columns 4032. The cable chain guide 401 then moves the bracket above the target object, the thin columns 4032 retract, and the rubber band is precisely fitted onto the object's surface. The entire process of the device is automated through the linkage of sensors and cylinders, ensuring the flexibility and precision of the rubber band placement operation.
[0042] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
