Description

Technical Field

[0001] This invention relates to the field of piston ring manufacturing technology, specifically to an automatic identification and marking device for piston ring end faces. Background Technology

[0002] Piston rings are metal rings that fit inside the grooves of a piston. They are a core component of a combustion engine, working together with the cylinder, piston, and cylinder walls to seal the fuel-gas mixture. Because there are slight differences in the structure of the front and back sides of a piston ring, attention must be paid to its orientation during installation. To avoid misalignment, markings are usually made on the end faces of the piston rings during manufacturing.

[0003] Existing technologies often use laser marking machines for marking. During the marking process, the piston rings are manually fed and the front and back sides are adjusted to ensure the accuracy of the marking end face. This method is labor-intensive and prone to errors.

[0004] The piston ring orientation recognition and laser marking integrated machine disclosed in CN205262511U combines orientation recognition and laser marking to achieve both orientation recognition and marking simultaneously. However, after marking is completed, the detection of the marking status of the piston ring cannot determine whether the marking is correct and clear. In mass production, defective products may be mixed in, so it is necessary to propose improvements. Summary of the Invention

[0026] 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.

[0027] Please see Figures 1-7 In this embodiment of the invention, an automatic piston ring end face identification and marking device includes a worktable. A feeding mechanism 2 for feeding piston rings is fixedly installed on one side of the worktable. A marking detection mechanism 5 for marking piston rings is fixedly installed on one side of the top of the worktable. A cutting mechanism 4 for cutting piston rings is fixedly installed at the end of the worktable near the feeding mechanism 2. A frame 1 is fixedly connected to the top of the worktable. A material claw rotation mechanism 3 for gripping and moving piston rings is fixedly installed on the top of the inner wall of the frame 1. The cutting mechanism 4 and the material claw rotation mechanism 3 are both implemented using existing technologies.

[0028] The marking and inspection mechanism 5 includes an inspection frame 501. A receiving and shifting unit for shifting piston rings is provided on one side of the inner wall of the inspection frame 501. A laser marking machine 512 is fixedly installed on one side of the inspection frame 501.

[0029] The receiving and shifting unit includes a lifting guide rail 503, a transverse guide rail 504 slidably installed on the inner wall of the lifting guide rail 503, and a receiving frame 505 slidably installed on the inner wall of the transverse guide rail 504. The top of the receiving frame 505 is provided with a snap-fit ​​groove corresponding to the piston ring. By setting the receiving and shifting unit, the piston ring is limited in a vertical position and driven to move, which facilitates the marking operation of the marking and detection mechanism 5 and the material shifting operation of the piston ring.

[0030] A guide plate 502 is fixedly connected to the top of the inspection frame 501. A sorting unit is fixedly installed on the inner wall of the guide plate 502. The sorting unit includes a shift guide rail 506. A transfer motor is slidably installed on the inner wall of the shift guide rail 506. A transfer hanging rod 507 is fixedly connected to the output end of the transfer motor. By setting up the sorting unit, piston rings that are not marked are sorted, and piston rings that are marked are guided separately, so as to facilitate the separate collection and processing of different piston rings.

[0031] To facilitate the diversion and guidance of sorted piston rings, a partition plate 509 is fixedly connected to the inner wall of the inspection frame 501. A gap is left between one side of the partition plate 509 and the inner wall of the inspection frame 501. A discharge channel 508 is provided at the top of the gap, and an inclined plate is fixedly connected to one side of the top of the discharge channel 508. The inclined plate guides the piston rings into the discharge channel 508, preventing the piston rings from remaining on the top surface of the inspection frame 501. A discharge conveyor belt is rotatably installed at the bottom of the inner wall of the inspection frame 501. 510, a discharge port is provided at the bottom of one side of the testing frame 501, and an inclined discharge guide 511 is fixedly connected to one side of the discharge port; the discharge conveyor belt 510 is set corresponding to the discharge port; a testing camera 513 is fixedly installed on the top of one side of the testing frame 501, the testing camera 513 is inclined and its top surface is lower than the top surface of the testing frame 501, so as to avoid the testing camera 513 from obstructing the movement of the piston ring; the guide plate 502 is open on the side near the testing camera 513.

[0032] The feeding mechanism 2 includes a loading unit and a segmented pushing unit. The loading unit includes a loading rack 201. One end of the loading rack 201 is fixedly connected to a snap-fit ​​bracket, and one end of the snap-fit ​​bracket is snap-fitted to a loading rod 202. The other end of the snap-fit ​​bracket is fixedly connected to a docking tray 211. A loading guide rail 203 is fixedly installed in the middle of the loading rack 201. A loading pusher 204 is slidably installed on the inner wall of the loading guide rail 203. The loading guide rail 203 drives the loading pusher 204 to move, so that the piston ring on the loading rod 202 enters the limiting guide groove 206. By setting the loading rod 202, the piston rings are stacked in a way that is parallel to the loading direction, which improves the single loading efficiency. Since the loading rod 202 adopts a snap-fit ​​connection, the overall loading and replacement are also more convenient and faster.

[0033] The segmented pushing unit includes a mounting frame, a hanging frame 205 is fixedly connected to one side of the mounting frame, a feeding limit frame is fixedly connected to the bottom of the hanging frame 205, a limit guide groove 206 is opened in the middle of the feeding limit frame, a front pushing component is fixedly installed on the top of the hanging frame 205, the front pushing component includes a forward guide rail 207, a forward push plate is slidably installed on the inner wall of the forward guide rail 207, a vertical guide rail 208 is fixedly installed on one end of the forward push plate, and a front pushing frame 209 is slidably installed on the inner wall of the vertical guide rail 208.

[0034] A rear pusher is fixedly installed in the middle of the mounting frame. The rear pusher includes a rear pusher guide rail 215. An adjustment frame is slidably installed on the inner wall of the rear pusher guide rail 215. An adjustment screw 212 is fixedly installed on the inner wall of the adjustment frame. A support frame 213 is fixedly connected to the output end of the adjustment screw 212. A rear pusher frame 210 is fixedly connected to one end of the support frame 213.

[0035] To facilitate the unloading of the marked piston rings, a guide frame is provided on one side of the marking and detection mechanism 5. A guide rod is fixedly connected to the bottom of the guide frame. The end of the guide rod facing the marking and detection mechanism 5 is inclined upward and is set in correspondence with the guide plate 502.

[0036] In use, several piston rings to be processed are stacked on the loading rod 202 with their notches facing upwards. The two ends of the loading rod 202 are respectively engaged with the snap-fit ​​frame and the docking tray 211. Then, the feeding guide rail 203 is activated, which drives the feeding pusher 204 to move, so that the piston rings on the loading rod 202 enter the feeding limit frame, and their notches slide in the limit guide groove 206.

[0037] The operation is initiated by the front pusher component. The forward guide rail 207 drives the forward push plate and the vertical guide rail 208 to move horizontally. The vertical guide rail 208 drives the front pusher frame 209 to rise and fall, thereby realizing the lifting and horizontal movement of the front pusher frame 209. The front pusher frame 209 pushes part of the piston rings towards the rear pusher component.

[0038] The operation is started by the rear pusher. The rear pusher guide rail 215 drives the adjustment frame to move horizontally, the adjustment screw 212 drives the support frame 213 to rise and fall, and then drives the rear pusher frame 210 to rise and fall and move horizontally. The rear pusher frame 210 pushes the piston ring towards the cutting mechanism 4.

[0039] When the piston ring moves to a position close to the slitting mechanism 4, the material claw rotating mechanism 3 picks up a piston ring and places it into the slitting mechanism 4 for slitting. After slitting, the piston ring is picked up and placed into the guide plate 502 of the marking and detection mechanism 5. The receiving frame 505 provides limiting support, and the lifting guide rail 503 drives the receiving frame 505 to move down into the detection frame 501. The laser marking machine 512 marks the ring, and then the lowering guide rail drives the receiving frame 505 to reset. The detection camera 513 takes a picture, which is then identified manually or by an external image processing device. If the mark is clear, it is considered qualified; otherwise, it is considered unqualified.

[0040] In practice, the front and back of the piston ring can be detected by the detection camera 513, and the laser marking machine 512 can be controlled to make different marks on the front and back based on the detection results, thereby distinguishing the front and back of the piston ring.

[0041] When the marking is recognized as qualified, the transverse guide rail 504 drives the receiving frame 505 to move towards the moving guide rod, so that the guide tube passes into the piston ring. The lifting guide rail 503 drives the receiving frame 505 to move down, so that the piston ring separates from the guide rod and the piston ring slides down along the guide rod. When the marking is recognized as unqualified, the shifting guide rail 506 drives the transfer motor and the transfer hook 507 to approach the piston ring. The transfer motor drives the transfer hook 507 to rotate and hook the piston ring. Then the shifting guide rail 506 resets the transfer hook 507 and moves it to above the discharge channel 508. The transfer motor rotates and drives the transfer hook 507 to flip, so that the piston ring enters the detection frame 501 from the discharge channel 508. The discharge conveyor belt 510 starts and sends the piston ring out from the discharge port and is received and sent out by the discharge guide 511.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
