Detailed Implementation

[0017] Combination Figures 1 to 8 The automatic opening device for the sealing ring of the present invention will be further described.

[0018] An automatic opening device for sealing rings is characterized by comprising a frame 1 and a feeding mechanism 2, a cutting mechanism 3, a grinding mechanism 4, a conveying mechanism 7, and a discharging mechanism 6 disposed on a table 11 of the frame 1.

[0019] The feeding mechanism 2 includes a conveyor belt 21 and a baffle 22 arranged above the conveyor belt 21 to stop the conveying of the opening retaining ring 10. The conveyor belt 21 extends back and forth on the frame 1. The rear end of the conveyor belt 21 is the feeding position, and the front end of the conveyor belt 21 is the loading position. The baffle 22 is arranged at the loading position at the front end of the conveyor belt 21 to stop the opening retaining ring conveyed from back to front on the conveyor belt 21, so that the transfer mechanism 7 can clamp and load the material. The cutting mechanism 3 is located on the right side of the feeding mechanism 2. The system includes a cutting positioning table 32 located on the right side of the material position on the conveyor belt 21, a cutting blade assembly 312 located behind the cutting positioning table 32, a clamping assembly 34 and a cutting feed assembly 35 disposed on the cutting positioning table 32. The clamping assembly 34 can clamp the retaining ring to be opened on the cutting positioning table 32. The cutting feed assembly 35 is disposed in the cutting positioning table 32 and drives the retaining ring to be opened on the cutting positioning table 32 to move toward or away from the cutting blade assembly 312. The grinding mechanism 4 is located on the right side of the cutting mechanism 3 and includes a grinding positioning table 41 located on the right side of the cutting positioning table 32 and a grinding assembly 42 located behind the grinding positioning table 41. The grinding assembly 42 includes a grinding head assembly and a grinding feed assembly 421 that drives the grinding head assembly to move relative to the grinding positioning table 41. The transfer mechanism 7 is located in front of the feeding mechanism 2, the cutting mechanism 3 and the grinding mechanism 4, and includes a mounting frame 72, a feeding gripper assembly 74 and a feeding feed assembly 73. The feeding gripper assembly 74... The feeding assembly 73 is mounted on the mounting frame 72 and moves between the feeding mechanism 2, the cutting mechanism 3, and the grinding mechanism 4. The discharge mechanism 6 is located behind the grinding positioning table 41 and includes a frame 61, a discharge gripper assembly 63, and a discharge feeding assembly 62. The discharge gripper assembly 63 is mounted on the frame 61 via the discharge feeding assembly 62 and moves between the grinding mechanism 4 and the discharge port 12 of the frame 1.

[0020] In the feeding mechanism 2, the conveyor belt 21 is the prior art, located on the left side of the platform 11 of the frame 1, and consists of two front and rear rollers, a conveyor belt wound around the two rollers, and a drive motor that drives one of the rollers to rotate.

[0021] The baffle 22 has a V-shaped positioning groove with the opening of the V-shaped positioning groove facing the feed position. The retaining ring to be opened, which is conveyed from the feed position to the upper material position, will be positioned in the center of the V-shaped positioning groove for the transfer mechanism 7 to hold.

[0022] The mounting structure of the baffle 22 is as follows: the frame 1 platform 11 has a mounting rail extending forward and backward on the left side of the corresponding conveyor belt 21, and a T-shaped groove extending forward and backward on the mounting rail. The left side of the baffle 22 is fixed to the T-shaped groove of the mounting rail by a vertical plate 221 and corresponding bolts. The plate body of the baffle 22 spans across the top of the conveyor belt 21, stopping the retaining rings to be opened on the conveyor belt 21. The mounting structure of the baffle 22 allows the baffle 22 to move in the forward and backward direction to stop retaining rings of different sizes to be opened at different positions on the front and back of the conveyor belt 21 for clamping by the transfer mechanism 7.

[0023] In the cutting mechanism 3, the cutting positioning table 32 includes a cutting base frame 321 mounted on the frame 1, a sliding plate 322 that slides back and forth on the upper surface of the cutting base frame 321 via a slide rail, and a cutting positioning plate 323 fixed to the upper surface of the sliding plate 322 by bolts. The upper surface of the cutting positioning plate 323 has an annular cutting positioning groove 3231 for horizontally inserting the retaining ring to be opened. A cutting clearance opening 3232 is located on the rear side wall of the cutting positioning plate 323, extending from the outer side of the cutting positioning plate 323 to the inner side of the annular cutting positioning groove 3231, allowing the cutting blade assembly 312 to extend from the outside to the inside to cut the retaining ring. When it is necessary to cut openings for retaining rings of different sizes, the cutting positioning plate 323 with annular cutting positioning grooves 3231 of different diameters can be replaced to accommodate retaining rings of different sizes.

[0024] The cutting feed assembly 35 is disposed between the cutting base frame 321 and the slide plate 322, driving the slide plate 322 to move back and forth. The cutting feed assembly 35 is a cutting feed cylinder, the cylinder body of which is mounted on the cutting base frame 321, and the piston rod is connected to the slide plate 322, driving the slide plate 322 and the cutting positioning plate 323 on the slide plate 322 to move back and forth.

[0025] Two sets of clamping assemblies 34 are located near the rear of the slide plate 322 and on the left and right sides of the cutting positioning plate 323. Each set of clamping assemblies 34 includes a clamping cylinder 342 and a pressure rod 341 mounted on the clamping cylinder 342. The clamping cylinder 342 is mounted on the lower surface of the slide plate 322. The upper end of the piston rod of the clamping cylinder 342 extends through the slide plate 322 to the top of the cutting positioning plate 323 for mounting the pressure rod 341. After the clamping cylinder 342 retracts, it drives the pressure rod 341 to move downward, so that the two pressure rods 341 press against both sides of the part of the retaining ring to be cut, ensuring the stability of the retaining ring during cutting.

[0026] The cutting blade assembly 312 includes a cutting motor 3121 mounted on the frame 1 via a bracket and a cutting wheel 3122 connected to the shaft of the cutting motor 3121. The cutting wheel 3122 corresponds to the cutting clearance opening 3232. When the cutting feed assembly 35 drives the cutting positioning plate 323 and the retaining ring to move toward the cutting wheel 3122, the cutting wheel 3122 gradually enters the cutting clearance opening 3232 and cuts the retaining ring in the annular cutting positioning groove 3231.

[0027] A dust cover 31 is provided on the cutting blade assembly 312. This dust cover has a front-opening structure, allowing the retaining ring to contact the cutting wheel 3122. A dust suction pipe 311 is connected to the rear side wall of the dust cover 31, and the other end of the dust suction pipe 311 has a dust collection box, which is placed in the frame 1. The dust cover 31 can prevent cutting waste from splashing, and at the same time, the dust suction pipe can effectively absorb the generated cutting waste to ensure the hygiene of the equipment during use.

[0028] In the grinding mechanism 4, the grinding positioning table 41 includes a grinding base frame 411 mounted on the frame 1 and a grinding positioning plate 412 bolted to the grinding base frame 411. The upper surface of the grinding positioning plate 412 is provided with an annular grinding positioning groove 4121 for horizontal placement of the retaining ring to be ground. A notch 4122 is provided on the rear side wall of the grinding positioning plate 412, which penetrates the outer groove wall and bottom wall of the annular grinding positioning groove 4121, so that the cutting part of the retaining ring to be ground is exposed on the outside of the grinding positioning plate 412. When it is necessary to cut and grind retaining rings of different diameters, the grinding positioning plate 412 with different annular grinding positioning grooves 4121 can be replaced to allow retaining rings of different diameters to be placed and ground.

[0029] After the retaining ring is cut and opened, burrs will be generated at the cut part. Therefore, the notch 4122 on the grinding positioning plate 412 makes the upper surface, lower surface and side of the retaining ring at the corresponding cut position exposed on the outside of the grinding positioning plate 412, which facilitates the contact and grinding of the grinding head assembly.

[0030] The grinding head assembly comprises two groups: a surface grinding head group 423 and a side grinding head group 422. Both the surface grinding head group 423 and the side grinding head group 422 include a grinding motor 4224, a connector 4223 connected to the shaft of the grinding motor 4224, a chuck 4222 connected to the connector 4223, and a wool grinding head 4221 connected to the chuck 4222. The wool grinding head 4221 in the surface grinding head group 423 extends forward and backward and is used for grinding the upper and lower surfaces of the retaining ring cutting area. The wool grinding head 4221 in the side grinding head group 422 extends in the same direction as the retaining ring cutting opening and is used for grinding the outer wall of the retaining ring cutting area.

[0031] The grinding feed assembly 421 is located behind the grinding positioning table 41 and includes an X-axis cylinder 4211 mounted on the frame 1, a Y-axis cylinder 4213 mounted on the X-axis cylinder 4211, and a Z-axis cylinder 4212 mounted on the X-axis cylinder 4211. The grinding motor in the surface grinding head assembly 423 is mounted on the slider of the Z-axis cylinder 4212, and the grinding cylinder in the side grinding head assembly 422 is mounted on the slider of the Y-axis cylinder 4213. The X-axis is the left-right direction of the frame 1, the Y-axis is the front-back direction of the frame 1, and the Z-axis is the height direction of the frame 1. Through the grinding feed assembly 421, the wool grinding head 4221 in the surface grinding head assembly 423 can contact and grind the upper and lower surfaces of the retaining ring cutting position, and the wool grinding head 4221 in the side grinding head assembly 422 can contact and grind the outer surface of the retaining ring cutting position.

[0032] When grinding the upper surface, the retaining ring is pressed down, and when grinding the outer side, the retaining ring is pressed inward, so no other clamping mechanism is needed. When grinding the lower surface, the retaining ring is pushed upward. During this process, the retaining ring is clamped in the annular grinding positioning groove 4121 by the discharge clamping assembly 63 in the discharge mechanism 6, so no clamping mechanism is needed.

[0033] In the transfer mechanism 7, the mounting frame 72 is slidably fitted onto a slide rail extending forward and backward on the platform 11 of the frame 1. A mounting frame feeding assembly 71 is provided between the frame 1 and the mounting frame 72 to drive the mounting frame 72 to move forward and backward. The mounting frame feeding assembly 71 includes a screw mounted on the platform 11 of the frame 1 and a nut sleeve mounted on the mounting frame 72 that engages with the screw. Rotating the screw will drive the mounting frame 72 to move forward and backward on the frame 1.

[0034] The feeding gripper assembly 74 includes a connecting frame 742 mounted on the feeding feed assembly 73 and two sets of gripper assemblies 741 mounted on the connecting frame 742 and distributed along the left-right direction of the frame 1. Each set of gripper assemblies 741 includes two finger cylinders 7411 distributed along the left-right direction of the frame 1 and gripping fingers 7412 mounted on the finger cylinders 7411. The two sets of gripper assemblies 741 can simultaneously transfer two retaining rings, that is, they can transfer the retaining rings on the loading position to the cutting mechanism 3, and at the same time transfer the retaining rings cut on the cutting mechanism 3 to the grinding mechanism 4. Each retaining ring is gripped by two left and right finger cylinders 7411, which can significantly improve the stability of retaining ring gripping.

[0035] To facilitate the gripping of the finger clamp 7412 on the finger cylinder 7411 onto the cutting positioning plate 323 or the grinding positioning plate 412, clearance grooves 8 are provided on both sides of the annular cutting positioning groove 3231 on the cutting positioning plate 323 and on both sides of the annular grinding positioning groove 4121 on the grinding positioning plate 412. The clearance grooves 8 are connected to the cutting positioning groove 3231 and the grinding positioning groove 4121.

[0036] The connecting frame 742 includes a connecting plate 7422 connected to the feeding assembly 73 and a mounting arm 7421 connected to the connecting plate 7422 and extending in a left-right direction. The mounting arm 7421 has a mounting groove extending in a left-right direction, on which a finger cylinder 7411 is mounted. When it is necessary to clamp retaining rings of different sizes, the finger cylinder 7411 can be moved on the mounting groove to adjust the distance between the two finger cylinders 7411 in each clamping assembly 741.

[0037] The feeding assembly 73 includes a lifting cylinder 732 that slides left and right on the slide rail of the mounting frame 72 and a ball screw pair 731 disposed between the mounting frame 72 and the lifting cylinder 732. The slider of the lifting cylinder 732 is connected to the connecting plate 7422 in the connecting frame 742. The ball screw pair 731 drives the lifting cylinder 732 to move in the left and right direction of the frame 1 to transfer the retaining ring held by the clamping hand assembly 741.

[0038] In the discharge mechanism 6, the frame 1 is provided with a mounting plate 5 on the rear side of the corresponding grinding positioning table 41 and above the grinding feed group 421. The mounting plate 5 is mounted on the table surface 11 of the frame 1 by multiple columns. The frame body 61 is slidably fitted on the slide rail on the mounting plate 5. A frame body feeding assembly is provided between the mounting plate 5 and the frame body 61 to drive the frame body 61 to move back and forth. The structure of the frame body feeding assembly is the same as that of the mounting frame feeding assembly 71. It drives the frame body 61 to move in the front and back direction of the frame 1 to clamp and transfer retaining rings of different sizes.

[0039] The structure of the discharge feeding assembly 62 is the same as that of the feeding assembly 73, and the discharge gripper assembly 63 is moved between the grinding positioning table 41 and the discharge port 12 of the frame 1.

[0040] The only difference between the structure of the discharge gripper assembly 63 and the structure of the feeding gripper assembly 74 is that in the discharge gripper assembly 63, the gripper group 741 is only one set, and the rest of the structure is the same. Together with the discharge feed assembly 62, it moves the retaining ring on the grinding positioning table 41 to the discharge port 12 on the right side of the frame 1.

[0041] In use, each mechanism works in conjunction with the equipment's control system and the corresponding sensors. The control system can be a PLC.

[0042] The specific process is as follows: the injection-molded retaining ring is placed on the feeding position of the conveyor belt 21 by the robot arm, and then conveyed to the loading position by the conveyor belt 21; The transfer mechanism 7 clamps the retaining ring on the loading position and then transfers it to the cutting positioning table 32 in the cutting mechanism 3. The cutting feed assembly 35 drives the cutting positioning plate 323 and the retaining ring to move toward the cutting wheel 3122, so that the cutting wheel 3122 completes the cutting operation on the retaining ring. Then the cutting feed assembly 35 is reset. The transfer mechanism 7 clamps the cut retaining ring on the cutting positioning plate 323 and transfers it to the grinding positioning plate 412 in the grinding mechanism 4. At the same time, the transfer mechanism 7 transfers the retaining ring to be cut on the loading position to the cutting positioning plate 323 for cutting. The grinding feed group 421 drives the surface grinding head group 423 and the side grinding head group 422 to grind the upper and lower surfaces and the outer surface of the corresponding cutting position of the retaining ring, respectively. The discharge mechanism 6 clamps the polished retaining ring and then moves it to the discharge port 12 located on the right side of the frame 1, and repeats this operation.
