[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0023] Please see Figure 1 The present invention provides an automatic assembly mechanism for rubber rings, used to assemble ring-shaped rubber rings A onto product B. The mechanism includes: a machine base 1, a rubber ring feeding mechanism 2 disposed on the side of the machine base, a loading mechanism 3 disposed on the machine base, a picking mechanism 4, a tooling top-rotating mechanism 5, and a conveyor line 6 for conveying product B. The rubber ring feeding mechanism arranges multiple rubber rings in an orderly manner and sequentially feeds them to the loading mechanism. The loading mechanism straightens the ring-shaped rubber rings A in the receiving groove and detects whether the ring-shaped rubber rings A in the receiving groove are in place. The tooling top-rotating mechanism clamps product B from the conveyor line and rotates it 90 degrees to the installation position. The picking mechanism inserts the ring-shaped rubber ring A from the receiving groove and moves it to the tooling top-rotating mechanism to install the ring-shaped rubber ring A onto product B, completing the assembly. To improve assembly efficiency, the rubber ring feeding mechanism, loading mechanism, picking mechanism, and tooling top-rotating mechanism in this invention are all dual-station units.

[0024] Specifically, the rubber ring feeding mechanism includes a vibratory plate and a direct vibration mechanism. The upper edge of the vibratory plate is provided with an outwardly connected transmission track 21. The transmission track of the vibratory plate is connected to the product receiving groove in the feeding mechanism. In this invention, the vibratory plate continuously feeds material, and the ring-shaped rubber ring A is sequentially sent out along the transmission track.

[0025] Please see Figure 2-3The feeding mechanism comprises two parts: a straightening mechanism and a detection mechanism. The straightening mechanism includes a first base plate 301, a second base plate 302 fixedly mounted on the first base plate, a straightening cylinder 303 mounted on the second base plate, and a third base plate 304 and a fourth base plate 305 slidably mounted within the first base plate. The second base plate has a receiving groove 306 for holding an annular rubber ring A. One side of the third base plate is connected to the piston rod of the straightening cylinder, and the other side is connected to the fourth base plate. The fourth base plate has a back... One end of the third base plate has an inclined pushing surface (not shown in the figure). A straightening block 307 is elastically provided on the side of the receiving groove. The straightening block is elastically connected to the second base plate through an elastic element and applies an elastic thrust to the ring-shaped rubber ring A in the receiving groove to facilitate the straightening of the ring-shaped rubber ring A in the receiving groove. The end face of the straightening block that contacts the ring-shaped rubber ring A in the receiving groove is an arc-shaped structure that matches the ring-shaped rubber ring A. A cam follower (not shown in the figure) is provided below the straightening block. The cam follower can slide against the inclined pushing surface of the fourth base plate.

[0026] In addition, the second base plate is also provided with a first cover plate 308 and a second cover plate 309. The first cover plate is used to limit the vertical position of the third base plate, and the second cover plate is used to limit the vertical position of the straightening block.

[0027] During operation, the ring-shaped rubber ring A first flows into the receiving groove and contacts the arc-shaped end face of the straightening block. When the piston rod of the straightening cylinder extends, the inclined push surface on the fourth base plate pushes the cam follower connected to the straightening block to move backward, facilitating the picking and placing of the ring-shaped rubber ring A. When the piston rod of the straightening cylinder retracts, the inclined push surface on the fourth base plate disengages from the cam follower, causing the straightening block to extend forward elastically, thereby straightening the ring-shaped rubber ring A. When the material picking mechanism picks up the material, the action of the straightening cylinder drives the inclined push surface on the fourth base plate to push the cam follower connected to the straightening block backward. At this time, the spring is compressed. After picking up the material, the straightening cylinder retracts, and the straightening block returns to its original position by the elastic force of the spring.

[0028] Specifically, the detection mechanism includes a height-adjustable upright plate 310 set on the side of the second base plate, a guide post 311 rotatably connected to the upright plate at one end, and a fixing plate 312 set on the other end of the guide post. A first photoelectric detector 313 is set on the fixing plate. The guide post is installed on the upright plate and can be rotated and positioned relative to the upright plate. Specifically, this can be achieved by setting a slot and a locking screw on the upright plate. The fixing plate can be connected to the guide post in an adjustable position relative to the guide post. Alternatively, it can be achieved by setting a slot and a locking screw or other existing technologies. The photoelectric detector is used to detect whether the ring-shaped rubber ring A in the receiving groove is present and whether it is in place.

[0029] Please see Figure 4-5The material handling mechanism 4 includes: a linear motion module 41 mounted on the frame, a sliding plate 42 mounted on the linear motion module, a material handling cylinder 43 mounted on the sliding plate, a pushing cylinder 44 mounted on the material handling cylinder, and a material handling nozzle 45. A material handling nozzle mounting plate 46 is provided on the output end of the material handling cylinder. The material handling nozzle is mounted on the material handling nozzle mounting plate to facilitate the insertion and removal of the ring-shaped rubber ring A. A pushing plate 47 is provided on the output end of the pushing cylinder. The lower end of the pushing plate passes through the material handling nozzle mounting plate and is bent towards the material handling nozzle to form a pushing end 471. The pushing end has a through hole through which the material handling nozzle can pass. The pushing end moves downward under the driving force of the pushing cylinder, which can easily remove the ring-shaped rubber ring A inserted on the material handling nozzle and push it onto the product B.

[0030] Specifically, it also includes a second photoelectric detector 48 for detecting whether there is an annular rubber ring A on the feeding nozzle. The linear motion module drives the feeding cylinder to move laterally to the feeding mechanism position. The feeding cylinder descends to pick up the material. The second photoelectric detector detects whether there is an annular rubber ring A on the feeding nozzle. After picking up the material, it moves laterally to the position of the tooling top rotation mechanism. After the feeding cylinder descends, the pushing cylinder descends to push out the annular rubber ring A and install it onto the product B.

[0031] Please see Figure 6 The tooling top rotation mechanism includes a U-shaped tooling frame 501, a product clamping mechanism rotatably mounted on the two inner sidewalls of the U-shaped tooling frame, a rotation drive mechanism mounted on one side of the U-shaped tooling frame for driving the product clamping mechanism to rotate 90 degrees, and a lifting cylinder 502 mounted at the bottom of the U-shaped tooling frame. A lifting positioning plate 503 is mounted on the output end of the lifting cylinder. Specifically, the product clamping mechanism includes a clamping cylinder 505 rotatably mounted on the inner sidewall of the U-shaped tooling frame via a rotating shaft 504, and two sets of picking fingers 506 mounted on the clamping cylinder. An upper pressure plate 507 is also mounted between the two sets of clamping cylinders. The rotation drive mechanism includes a rack drive cylinder 508 mounted on the outer sidewall of the U-shaped tooling frame, a rack 509 mounted on the output end of the rack drive cylinder, and a gear 510 meshing with the rack. The gear is mounted on... A support plate 511 is installed below the rack on the rotating shaft. The support plate is slidably connected to the linear guide rail 512 on the outer wall of the U-shaped tooling frame. During operation, when product B is conveyed to the position on the production line, the rack drive cylinder extends and drives the rack to move and rotate in conjunction with the gear, thereby driving the entire product clamping mechanism and the upper pressure plate to rotate 90 degrees simultaneously. Two sets of picking fingers clamp the tooling plate on which product B is placed. At this time, the lifting cylinder drives the lifting positioning plate to rise and contact the bottom of product B for positioning. At the same time, the upper pressure plate is composed of a plate and four corner springs, which elastically buffers the contact with the top of product B, making it less likely to damage the product. After positioning, the rack drive cylinder retracts and drives the entire product clamping mechanism and the upper pressure plate to rotate back to the initial position. The picking cylinder in the picking mechanism moves to the assembly station, and the pushing cylinder descends to push out the ring-shaped rubber ring A and install it on product B.

Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
