Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to an optical detection equipment for the appearance of a rubber sealing ring. Background Art

[0002] A sealing ring, also known as an oil seal, is an annular cover consisting of one or more parts, fixed to a ring or washer on a bearing, in contact with another ring or washer or forming a narrow labyrinth gap. Its main function is to provide an effective and reliable seal between two mating surfaces to prevent liquid or gas leakage.

[0003] Seals are widely used in various industries such as automotive, aerospace, and manufacturing. In car engines, seals ensure that the combustion chamber remains sealed to prevent gas leakage during the combustion process. In hydraulic systems or pipelines, seals act as barriers to prevent dirt, dust or other contaminants from entering the system. In addition, seals also help keep moving parts running normally and provide necessary lubrication to reduce friction and wear.

[0004] In actual production, the sealing ring requires high quality. Flaws or defects on its surface will affect the sealing effect. However, the existing detection method is generally to manually hold the sealing ring for flipping detection, which wastes manpower. The hands will shake after holding it for a long time, which affects the visual observation effect of the eyes and thus affects the detection quality. Therefore, a rubber sealing ring detection device is proposed. Summary of the invention

[0005] In order to solve the above-mentioned existing problems, the present invention provides an optical inspection device for the appearance of rubber sealing rings.

The positioning clamping mechanism ensures that the inner and outer walls of the sealing ring can be accurately inspected. The screening and classification mechanism realizes automatic classification of unqualified and qualified products through the cooperation of servo motors, hydraulic devices and expansion pumps, thereby avoiding human errors.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention designs a unique expansion mechanism, which increases the pressure of the expansion groove by working the booster pump, thereby pushing the four expansion blocks to slide outward on the side walls of the expansion groove until the expansion sealing ring is tightly fitted with the outer wall of the rotating seat. This design effectively solves the problem in the prior art that the sealing ring is too soft to be automatically fixed and clamped, and achieves the technical effect of expanding and fixing the sealing ring;

[0018] (2) In order to facilitate the all-round detection of the sealing ring, the present invention also introduces a posture adjustment mechanism, which allows the adjustment seat to slide in the adjustment groove, thereby driving the expansion seat to move together. As the adjustment seat moves, the rotating rod slides in the rotating groove. Since the rotating groove is designed from high to low, the rotating rod and the expansion seat will rotate relative to the adjustment seat, and finally the adjustment seat will rotate 90 degrees, thereby completing the fully automatic posture adjustment of the sealing ring;

[0019] (3) In order to solve the problem of detecting the inner and outer walls of the sealing ring, the present invention designs a positioning clamping mechanism. When the sealing ring is moved into the ring mechanism through the posture adjustment mechanism, it will first be fixed by the outer wall. Then, the rotation detection mechanism will be inserted into the card slot of the rotating seat to realize the conversion from outer wall clamping to inner wall clamping. The rotation detection mechanism is responsible for propping up the inner wall of the sealing ring to facilitate the detection of its inner wall quality. This design effectively solves the problem of difficulty in detecting the inner wall of the sealing ring in the prior art.

[0020] (4) The present invention further comprises a screening and classification mechanism for identifying and classifying the sealing rings after the test. If the test result is unqualified, the classification servo motor will reverse and drive the test seat to move above the waste bin. Then, the hydraulic actuator will be selected to retract, so that the rotating seat will rotate 90 degrees on the side wall of the test seat. Then, the expansion pump will release the pressure, and the rotating L-shaped rod will move toward the axis of the rotating seat, releasing the control of the sealing ring and causing it to fall into the waste bin. On the contrary, if the test result is qualified, the test seat will be brought above the qualified bin and the sealing ring will fall into the qualified bin. This design avoids classification errors caused by human errors.

[0021] (5) In order to achieve comprehensive and automatic detection of the sealing ring, the present invention introduces an optical detection mechanism. The optical detector can detect the end faces and outer circumference of the sealing ring, thereby achieving a comprehensive and automatic detection effect, effectively solving the problem of manual detection required in the prior art.

It is fixed at the output end of the rotating servo motor 321, the rotating groove 325 is opened inside the rotating seat 324, the number of the rotating grooves 325 is four, the four rotating grooves 325 are connected, one end of the rotating L-shaped rod 326 is slidably arranged on the inner wall of the rotating groove 325, the expansion pump 327 is fixed on the side wall of the rotating seat 324, the expansion pump 327 is connected to the rotating groove 325, the sliding wheel 329 is fixed on the other end of the rotating L-shaped rod 326, and the optical detector is fixed on the side wall of the rotating L-shaped rod 326.

[0043] Among them, the adjusting servo motor 222, the rotating servo motor 212, the boosting pump 215, the optical detector 1 401, the detecting servo motor 402, the clamping hydraulic rod 312, the classifying servo motor 502, the selecting hydraulic device 506, the rotating servo motor 321, the expansion pump 327 and the optical detector 2 328 are electrically connected to the external electric control system through wires.

[0045] The rotating seat 211 is conical, a clamping groove is arranged in an array on the side wall of the rotating seat 211, the clamping groove 314 has the same radius as the sealing ring, and a convex ridge is arranged in an array on the inner wall of the clamping arc block 313.

[0046] When in use, the device is first placed under the external feeding device, so that the sealing ring covers the bottom end of the rotating seat 211 and falls on the main frame 1. Then, the user can control the booster pump 215 through the external electric control system (this is an existing mature technology and will not be described in detail here), so as to increase the pressure of the expansion groove 216, and then push the four expansion blocks 217 to slide on the side wall of the expansion groove 216 toward the outside of the expansion groove 216, so as to expand the sealing ring and the outer wall of the rotating seat 211, thereby achieving the technical effect of expanding and fixing the sealing ring, and effectively solving the technical problem that the sealing ring in the prior art is too soft to be automatically fixed and clamped;

[0047] Then the user can control the rotation of the servo motor 222 through the external electric control system, and the screw rod can be used to drive the adjustment seat 224 to slide on the inner wall of the adjustment groove 221, thereby driving the expansion seat 225 to slide, and then the rotation rod 226 can slide in the rotation groove 227. Since the rotation groove 227 is arranged from high to low, the rotation rod 226 and the expansion seat 225 can be rotated relative to the adjustment seat 224, and then the adjustment seat 224 can be rotated 90 degrees, realizing the full-automatic posture adjustment of the sealing ring, which is convenient for comprehensive detection of the sealing ring.

[0048] When the sealing ring moves to the position of the detection frame 403, the adjustment servo motor 222 will stop working, and the external electric control system will control the detection servo motor 402 to work. After the detection threaded rod 405 is driven, the detection frame 403 can slide in the detection groove 404, so that the notch of the detection frame 403 can surround the sealing ring. At this time, the three optical detectors 401 will respectively detect the end faces and the outer circumference of the sealing ring. Then the user can control the rotation servo motor 212 to rotate through the external electric control system, and the rotation of the rotating gear 213 and the rotating gear 214 can be driven to make the rotating seat 211 drive the sealing ring to rotate, so that the optical detector 401 can detect the sealing ring, thereby achieving the technical effect of comprehensively detecting the end faces and the outer circumference of the sealing ring, and effectively solving the technical problem of manual detection in the prior art;

[0049] After the detection is completed, the servo motor 222 is adjusted to continue rotating and bring the sealing ring to the position of the annular seat 311. At this time, the rotating servo motor 212 will rotate to adjust the position of the rotating seat 211 to ensure that the expansion block 217 corresponds to the clamping arc block 313. At this time, the clamping hydraulic rod 312 can be controlled to extend and the booster pump 215 can be decompressed, so that the sealing ring can completely enter the clamping groove 314 and fit completely with the clamping groove 314. Subsequently, the classification servo motor 502 can be controlled to work through the external electric control system, and the classification threaded rod 503 can be driven to make the detection seat 504 move toward the annular seat 311 in the classification groove 501. In this process, the rotating servo motor 321 can be driven to work through the rotating gear 322 and the rotating gear teeth 323, which can drive the rotating seat 324 and the rotating L-shaped rod 326 to rotate, so that the rotating L-shaped rod 326 can be inserted into the card slot of the rotating seat 211. , then the user can control the expansion pump 327 to work through the electrical control panel, which can increase the pressure in the rotating groove 325, thereby pushing the rotating L-shaped rod 326 to move from the rotating groove 325 to the outside of the rotating groove 325, so that the sliding wheel 329 can contact the inner wall of the sealing ring. Then the user can control the booster pump 215 to release pressure and adjust the servo motor 222 to reverse, thereby driving the rotating seat 211 to return to the initial position, and then the rotating servo motor 321 can be controlled to work, thereby driving the rotating seat 324 and the rotating L-shaped rod 326 to rotate, and the sliding wheel 329 rolls on the inner wall of the sealing ring. Since the inner wall of the clamping arc block 313 is covered with convex ridges, the rotation of the sealing ring will be restricted. At this time, the optical detector 2 328 will detect the inner wall of the sealing ring during the rotation process, achieving the technical effect of detecting the inner wall of the sealing ring, and effectively solving the technical problem that it is difficult to detect the inner wall of the sealing ring in the prior art;

[0050] After the detection is completed, the rotating servo motor 321 rotates the L-shaped rod 326 to correspond to the clamping arc block 313, and then controls the clamping hydraulic rod 312 to retract and the expansion pump 327 to increase pressure, so that the sealing ring can be separated from the clamping arc block 313 and be opened and fixed by the sliding wheel 329. The optical detector 1 401 and the optical detector 2 328 transmit the detection results to the external electronic control system. If the detection result is unqualified, the classification servo motor 502 reverses, which will drive the detection seat 504 to the top of the waste box 507, and then control the selection liquid The compressor 506 retracts, so that the rotating seat 324 can rotate 90 degrees on the side wall of the detection seat 504, and then the expansion pump 327 is controlled to release pressure, so that the rotating L-shaped rod 326 can move toward the axis of the rotating seat 324, and then contact the control of the sealing ring to make it fall into the waste box 507. If the test result is qualified, it will drive the detection seat 504 to the top of the qualified box 508 and fall into the qualified box 508, thereby achieving the technical effect of identifying and classifying the sealing ring after detection, and avoiding the mixing of the two caused by human errors.
