DETAILED DESCRIPTION

[0030] The utility model object of the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation methods of the utility model are not limited to the following embodiments.

[0031] like Figure 1 As shown, the automatic feeding mechanism for sponge rings includes an automatic feeding structure 1, a sponge ring handling robot 2, and a supporting base 3. The supporting base 3 includes a robot base plate 301 and a feeding base plate 302, which are connected to each other. The vibrating end of the automatic feeding structure 1 is mounted on the feeding base plate 302, and the discharge end of the automatic feeding structure 1 is mounted on the robot base plate 301. The sponge ring handling robot 2 is mounted on the robot base plate 301. The sponge ring handling robot 2 is capable of picking up sponge rings 4 at the discharge end of the automatic feeding structure 1. The automatic feeding structure 1 vibrates to deliver the sponge rings 4 from the inner cavity of the automatic feeding structure 1 and moves the sponge rings 4 to the discharge end, making it easier for the sponge ring handling robot 2 to pick up the sponge rings 4. The sponge ring handling robot 2 is used to pick up the sponge rings 4 at the discharge end of the automatic feeding structure 1 and rotate the sponge rings 90 degrees, making it easier for staff to pick up the sponge rings or for equipment in the next process to receive the materials. The supporting base 3 is used to support the automatic feeding structure 1 and the sponge ring handling robot 2.

[0032] like Figure 2As shown, the sponge ring handling robot 2 includes a robot bracket 21, a robot rotating structure 22, a position fine-tuning structure 24 and a sponge ring grabbing structure 23. The robot bracket 21 is installed on the robot base plate 301. The robot rotating structure 22 is installed on the robot bracket 21, the rear end of the position fine-tuning structure 24 is installed on the rotating end of the robot rotating structure 22, and the front end of the position fine-tuning structure 24 is connected to the sponge ring grabbing structure 23. The robot bracket 21 acts as a bracket. The robot rotating structure 22 is used to drive the sponge ring grabbing structure 23 to rotate, so that the sponge ring grabbing structure 23 can send the sponge ring 4 to the next process. The position fine-tuning structure 24 is used to fine-tune the position of the sponge ring grabbing structure 23 so that it can accurately grab the sponge ring 4. The sponge ring grabbing structure 23 is used to grab the sponge ring 4 on the automatic feeding structure 1.

[0033] like Figure 3 As shown, the manipulator rotating structure 22 includes a manipulator rotating motor 221 and a speed-shifting steering gear 222. The speed-shifting steering gear 222 is mounted on the manipulator bracket 21. The input end of the speed-shifting steering gear 222 is connected to the manipulator rotating motor 221, and the rotating end of the speed-shifting steering gear 222 is connected to the sponge ring grasping structure 23 via a position fine-tuning structure 24. The manipulator rotating motor 221 provides power for the steering of the sponge ring grasping structure 23. The speed-shifting steering gear 222 is used to change the speed of the manipulator rotating motor 221 and convert the power of the manipulator rotating motor 221 into rotation. The speed-shifting steering gear 222 can be purchased on the market.

[0034] like Figure 4-8As shown, the position fine-tuning structure 24 includes a first adjustment seat 241, a second adjustment seat 242, a locking screw, an adjustment screw 243 and two limiting posts 244. The first adjustment seat 241 is slidably connected to the second adjustment seat 242, and the second adjustment seat 242 is located below the first adjustment seat 241. An adjustment rail 242a is provided on the top of the second adjustment seat 242, and limiting grooves 242c are provided on both sides of the adjustment rail 242a. The limiting grooves 242c are located inside the second adjustment seat 242. An adjustment slider 241a is provided in the middle of the bottom of the first adjustment seat 241, and the adjustment slider 241a can slide relative to the adjustment rail 242a. The sliding ends of the two limiting posts 244 are installed in the two limiting grooves 242c. The limiting groove 242c includes a limiting portion 242ca, a guide portion 242cb and a clamping portion 242cc that are connected in sequence. The two limiting portions 242ca respectively limit the sliding ends of the two limiting columns 244, allowing them to slide only within a certain distance. Two locking screw holes 242b are provided on the sides of the limiting slot 242c. Two locking screws are respectively installed in the two locking screw holes 242b and lock the sliding ends of the limiting columns 244. The clamping ends of the two limiting columns 244 sequentially pass through the guide portion 242cb and the clamping portion 242cc of the limiting slot 242c and protrude to the outside. The first adjustment seat 241 is provided with two bayonet holes, and the clamping ends of the two limiting columns 244 are clamped into the two bayonet holes of the first adjustment seat 241. The adjusting screw 243 is threadedly installed on the end of the second adjustment seat 242 away from the limiting slot 242c, and the adjusting screw 243 abuts the end of the first adjustment seat 241 away from the bayonet hole.

[0035] Loosen the locking screw on the second adjustment seat 242 to unlock the limiting post 244, allowing the limiting post 244 to slide in and out of the limiting slot 242c, allowing the first adjustment seat 241 and the second adjustment seat 242 to slide relative to each other. Twist the adjusting screw 243, which pushes the first adjustment seat 241, which in turn drives the limiting post 244 outward, adjusting the relative position of the first adjustment seat 241 and the second adjustment seat 242, thereby fine-tuning the position of the sponge ring gripping structure 23. Once the sponge ring gripping structure 23 is positioned, tighten the locking screw on the second adjustment seat 242 to lock the two limiting posts 244, preventing them from sliding freely within the limiting slot 242c.

[0036] like Figure 9-11As shown, the sponge ring grabbing structure 23 includes a telescopic grabbing cylinder 231, a boss transmission rod 232, a groove grabbing rod 233, a cylinder fixing seat 234, a guide cylinder 235 and a manipulator base 236. The manipulator base 236 is installed in front of the position fine-tuning structure 24. The telescopic grabbing cylinder 231 is installed at the upper end of the manipulator base 236, and the lower end of the manipulator base 236 is provided with a cylinder fixing seat 234, and the guide cylinder 235 is installed on the cylinder fixing seat 234. The boss transmission rod 232 is connected to the rod head of the telescopic grabbing cylinder 231 by a thread, and the boss end of the boss transmission rod 232 is slidably connected to the groove end of the groove grabbing rod 233. The grabbing end of the groove grabbing rod 233 is slidably mounted in the guide cylinder 235.

[0037] The telescopic grabbing cylinder 231 provides power for the extension and retraction of the groove grabbing rod 233. The boss drive rod 232 cooperates with the groove grabbing rod 233 to fine-tune its position, preventing interference between the groove grabbing rod 233 and the guide cylinder 235. The cylinder fixing seat 234 secures the cylinder. The guide cylinder 235 guides the groove grabbing rod 233. The manipulator base 236 mounts the telescopic grabbing cylinder 231 and guide cylinder 235, ensuring they remain aligned.

[0038] like Figure 12 As shown, the automatic feeding structure 1 includes a vibrating material frame 101, a feeding track 102, a track bracket 103, a track base 104, four track support columns 105 and a material limiting frame 106. The vibrating material frame 101 is installed on the feeding base plate 302. The vibrating material frame 101 is provided with a material holding chamber, which is used to load the sponge ring 4. A track hole is provided on the side of the material holding chamber. The rear end of the feeding track 102 passes through the track hole and enters the material holding chamber. The other end of the feeding track 102 is wrapped by the material limiting frame 106. A sensor 106c is provided at the front end of the feeding track 102 for detecting whether there is a sponge ring 4 at the front end of the feeding track 102. The material limiting frame 106 is installed on the top of the track bracket 103 by bolts. The bottom of the track bracket 103 is installed on the track base 104, and the four corners of the track base 104 are installed on the right side of the manipulator base plate 301 through four track support columns 105.

[0039] The vibrating material frame 101 is used to accommodate the sponge ring 4 and is driven to vibrate so that it automatically enters the feeding track 102. The feeding track 102 is driven to vibrate by the vibrating material frame 101. During the vibration process, the sponge ring 4 is adjusted in position by the feeding track 102 and moves forward in the feeding track 102. The material limit frame 106 is used to prevent the sponge ring 4 from escaping from the feeding track 102 during the vibration process. The track bracket 103 is used to support the material limit frame 106. The track base 104 is used to indirectly support the feeding track 102, and the four track support columns 105 are used to adjust the level of the feeding track 102.

[0040] like Figure 13 As shown, the loading track 102 includes two guide plates 102a, a guide rail 102b, and a baffle 102c. The two guide plates 102a are mounted on either side of the rear end of the guide rail 102b. The rear portion of the guide rail 102b is mounted within the material holding chamber of the vibrating material frame 101. The baffle 102c is mounted on the front end of the guide rail 102b, and the front portion of the guide rail 102b is mounted on the track frame 106a of the material limiting frame 106. The material limiting frame 106 includes the track frame 106a, a cover plate 106b, and a sensor 106c. The track frame 106a is mounted on the track bracket 103, and the cover plate 106b is mounted on the track frame 106a. The cover plate 106b covers the top of the front portion of the guide rail 102b of the loading track 102. The sensor 106c is mounted on the front end of the track frame 106a.

[0041] The guide plate 102a is used to guide the sponge ring 4 into the guide rail 102b. The guide rail 102b is used to transfer the sponge ring 4 from the vibrating material frame 101 to the outside. The baffle 102c is used to limit the sponge ring 4 to prevent it from leaving the guide rail 102b. The track frame 106a is used to support the guide rail 102b and is equipped with a sensor 106c. The cover plate 106b is used to prevent the sponge ring 4 from leaving the guide rail 102b. The sensor 106c is used to detect whether the sponge ring 4 is in place.

[0042] The automatic sponge ring feeding mechanism operates as follows: The vibrating material frame 101 vibrates, driving the feeding track 102 to vibrate. The vibrations force the sponge rings 4 within the vibrating material frame 101 into the feeding track 102. The rear end of the feeding track 102 adjusts the position of the sponge rings 4 until they are positioned as designed. Under the action of vibration, the sponge ring 4 moves from back to front in the feeding track 102 until the sponge ring 4 reaches the front end of the feeding track 102. After the sensor 106c at the front end of the feeding track 102 senses the sponge ring 4, it feeds back to the sponge ring grabbing structure 23 of the sponge ring handling robot 2. The telescopic grabbing cylinder 231 of the sponge ring grabbing structure 23 pushes the telescopic grabbing rod to move downward. A guide column is provided at the top of the telescopic grabbing rod. The guide column is pressed into the inner ring of the sponge ring 4. Because the outer diameter of the guide column is slightly larger than the inner ring, the sponge ring 4 is inserted into the lower end of the telescopic grabbing rod under the elastic action of the sponge ring 4. The telescopic grabbing cylinder 231 drives the telescopic grabbing rod to retract into the guide cylinder 235 to avoid interference between the groove grabbing rod 233 and the feeding track 102, and also prevents the sponge ring from escaping from the groove grabbing rod 233 during rotation. The manipulator rotating structure 22 drives the sponge ring grabbing structure 23 to rotate 90° clockwise. Under the control of the telescopic grabbing cylinder 231, the groove grabbing rod 233 brings the sponge ring 4 out of the guide cylinder 235, making it convenient for the staff to take it or deliver it to the equipment station of the next process.

[0043] The above specific implementation methods are preferred embodiments of the present invention and cannot limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the scope of protection of the present invention.
