Description

Technical Field

[0001] The utility model relates to the field of blind rivet processing, in particular to a detection system and a processing system for the blind rivets. Background Art

[0002] Blind rivets are a type of rivet used for single-sided riveting. During riveting, a dedicated rivet gun pulls the mandrel, and the mandrel's head expands the rivet body, achieving the riveting effect. However, existing blind rivets are generally formed through assembly line processing, with the mandrel pre-assembled in the rivet body. Assembly line processing inevitably produces defective products. Existing blind rivets are not fully inspected during inspection. For example, only the side of the blind rivet or the side of the mandrel is inspected. On the one hand, the cylindrical shape of the blind rivet limits the inspection angle of the blind rivet. On the other hand, the pre-fit position between the mandrel and the rivet body is not fully inspected. As a result, existing blind rivets have the problem of not being effectively inspected. If the defects of the blind rivet are not detected, it cannot be removed in time. Utility Model Content

[0048] like Figure 1-6 , a blind rivet detection system, comprising: a feeding device 1 and a detection device 2;

[0049] The feeding device 1 comprises: a feeding turntable 11 and an arc rib 12;

[0050] The feed turntable 11 is relatively rotatably arranged on the inner ring of the arc rib 12; the outer edge of the feed turntable 11 is provided with a plurality of feed grooves 111 for accommodating the core 91 of the blind rivet 9, and the bottom of the rivet body 92 of the blind rivet 9 is against the top of the feed groove 111; the notches of some of the feed grooves 111 face the inner ring of the arc rib 12, and form a clamping mouth 110 with a limiting function;

[0051] The detection device 2 includes: a rivet body top detection mechanism 21, a nail core outer side detection mechanism 22 and a multi-angle detection mechanism 23; the feeding groove 111 rotates to a detection end passing through the rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23 respectively;

[0052] The detection end of the rivet body top detection mechanism 21 is downwardly directed toward a portion of the feeding groove 111 , and is used to detect the tops of both the rivet body 92 and the nail core 91 .

[0053] The detection end of the nail core outer side detection mechanism 22 is horizontally directed toward a portion of the feeding groove 111, and is used to detect the nail core 91 extending below the bottom of the rivet body 92;

[0054] The plurality of multi-angle detection mechanisms 23 are distributed around the outer circumference of a portion of the feeding groove 111 and are respectively used to detect the outer surface of the rivet body 92 at multiple angles.

[0055] The present solution provides a detection system for blind rivets, which surrounds the arc rib 12 on the outer ring of the feed turntable 11 to form a clamp 110 with a limiting function. The rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23 are distributed along the arrangement direction of the clamp 110. The blind rivet 9 can be detected from multiple angles to ensure that multiple positions of the blind rivet 9 can be detected, thereby solving the problem that the existing blind rivet 9 cannot be effectively detected and cannot be removed in time.

[0056] Specifically, the feeding turntable 11 is installed in a relatively rotatable manner on the inner ring of the arc rib 12. The arc rib 12 drives the arc structure, and the arc structure extends to the feeding groove 111 on the outer edge of the feeding turntable 11. The feeding groove 111 of the feeding turntable 11 can form a clamp 110 with the inner ring of the arc rib 12. Since the clamp 110 blocks the notch of the feeding groove 111, or the distance between the notch of the feeding groove 111 and the inner ring of the arc rib 12 is smaller than the outer diameter of the blind rivet 9, the blind rivet 9 can only be limited to the clamp 110, and the clamp 110 has a limiting function. Thus, when the feeding turntable 11 rotates, it can drive the blind rivet 9 in the feeding groove 111 to rotate, so that the blind rivet 9 passes through the detection ends of the rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23; and the blind rivet 9 detected by this scheme, according to common knowledge, the blind rivet 9 is composed of a rivet body 92 and a nail core 91. When in use, the nail head of the nail core 91 at the top will cause the rivet body 92 to expand; like this, this scheme is to place the rivet body 92 of the blind rivet 9 on the top and the nail core 91 on the bottom in the feeding groove 111, so that the top of the rivet body 92 and the nail head of the nail core 91 in the feeding groove 111 are located above the feeding groove 111. In this way, when the feeding turntable 11 rotates to transmit the blind rivet 9 of the feeding groove 111 to the detection device 2, the rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23 can respectively detect different positions of the blind rivet 9; for the rivet body top detection mechanism 21, its detection end is downward toward the blind rivet 9 with the feeding groove 111 partially in place, and the top of the rivet body 92 and the nail head at the top of the nail core 91 can be detected to ensure that the top of the blind rivet 9 is free of defects; for the nail core outer side detection mechanism 22, it mainly detects the nail core 91 of the blind rivet 9 below the bottom of the rivet body 92 to ensure that the nail core 91 of the lower half is vertical, without bending, and also ensures that the length is normal; for the multi-angle detection mechanism 23, it mainly detects the outer surface of the rivet body 92. Since the number of the multi-angle detection mechanisms 23 is multiple, the multi-angle detection mechanisms 23 at different positions can respectively detect different surfaces of the rivet body 92, thereby detecting surface defects of the rivet body 92 from multiple angles. In this way, the rivet body 92 of a single blind rivet 9 can be inspected from multiple angles on the side, the section of the mandrel 91 extending below the rivet body 92 can be inspected, and the mating position of the mandrel 91 and the rivet body 92 at the top can also be inspected, so that the blind rivet 9 can be fully inspected. The inspection system of this solution can improve the inspection accuracy of the blind rivet, and solves the problem that the existing blind rivet 9 cannot be effectively inspected and cannot be removed in time.

[0057] The rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23 are well-known mechanisms with visual defect detection and identification functions, such as industrial cameras, which mainly obtain an image of the workpiece and compare it with a standard image, and then determine whether the obtained image has defects through image comparison.

[0058] The rotation of the feeding turntable 11 can be achieved in a well-known manner. For example, in one embodiment, the center of the feeding turntable 11 is connected to the rotating shaft of the motor, and the motor is started to drive the feeding turntable 11 to rotate.

[0059] Optimally, it further comprises: a feeding device 3;

[0060] The notch of a single feeding groove 111 rotates through the output end of the feeding device 3 and the arc rib 12 in sequence; the output end of the feeding device 3 is connected to the feeding groove 111, and the feeding device 3 is used to transport the blind rivet 9 to the feeding groove 111.

[0061] The feed turntable 11 is rotatable, and its rotation drives the multiple feed grooves 111 to rotate, so that the feed grooves 111 pass through different devices, such as the detection device 2, the feeding device 3, etc., so that the notches of the feed grooves 111 are exposed from the specific devices or form a clamp 110. When the notches of the feed grooves 111 rotate to face the output end of the feeding device 3, the feeding device 3 can output the blind rivets 9 to the feed grooves 111, and the feed grooves 111 can rotate again to face the arc rib 12, thereby forming a clamp 110 that restricts the blind rivets 9 from escaping. In this way, the present solution only needs to continuously output the blind rivets 9 to the feeding grooves 111 passed by the feeding device 3, and can continuously input the blind rivets 9 to the feed turntable 11, thereby realizing the function of automatic feeding.

[0062] Optimally, the feeding device 3 includes: a feeding vibration plate 31 and a feeding track 32;

[0063] The output end of the feed vibration plate 31 is connected to the input end of the feed track 32 , and the single feed groove 111 rotates to pass through the output end of the feed track 32 and the inner circle of the arc rib 12 in sequence.

[0064] The feeding vibration plate 31 is a well-known mechanism, which automatically and orderly arranges the disordered blind rivets 9 and accurately delivers them to the input end of the feeding track 32 through the vibration action. The blind rivets 9 are then transferred from the feeding track 32 to the feeding groove 111 passing through the output end of the feeding track 32; after the feeding groove 111 receives the blind rivet 9, it is transferred to the inner circle of the arc rib 12, so that the feeding groove 111 can seamlessly connect with the arc rib 12 after receiving the blind rivet 9, thereby ensuring that the blind rivet 9 can be limited after receiving it.

[0065] Optimally, the feeding device 3 includes: a discharge plate 33 and a feeding blowing device 34;

[0066] The discharge plates 33 are arranged in pairs at the output end of the feed track 32, and a discharge port 331 is formed between the two discharge plates 33; the input end of the discharge port 331 is connected to the output end of the feed track 32, and the output end of the discharge port 331 faces the feeding groove 111; the discharge port 331 is used to clamp the rivet body 92 of the blind rivet 9, so that the bottom of the blind rivet 9 is suspended in the air;

[0067] The output end of the feeding blowing device 34 faces the discharge port 331 and is used for blowing air toward the discharge port 331 to transfer the blind rivet 9 in the discharge port 331 to the feeding groove 111 .

[0068] The discharge plates 33 are arranged in pairs, which are arranged at the output end of the feed track 32, so that the discharge port 331 formed between the discharge plates 33 is connected to the output end of the feed track 32 at one end, and is connected to the feeding groove 111 at the other end; the discharge plates 33 are used to clamp the rivet body 92, so that the bottom of the blind rivet 9 can be suspended in the air, and the nail core 91 at the bottom of the blind rivet 9 is suspended and will not contact the other mechanisms, which is more convenient for driving the feeding blowing device 34; and the blind rivet 9 is light in weight, and it only needs to blow air to the discharge port 331 through the output end of the feeding blowing device 34. The blind rivet 9 is transferred from the discharge port 331 to the feeding groove 111 under the action of the airflow, thereby realizing rapid feeding of the blind rivet 9, avoiding direct contact of the other mechanisms with the blind rivet 9, and preventing surface wear of the blind rivet 9. At the same time, the feeding air blowing device 34 blows air toward the blind rivet 9 , which can blow away impurities on the surface of the blind rivet 9 and reduce the impact of the impurities on the subsequent detection device 2 .

[0069] The feeding air blowing device 34 is a well-known mechanism with gas output, and it is sufficient as long as the flow rate of the gas reaches a level that drives the blind rivet 9 to move.

[0070] Optimally, it further comprises: a rejection device 4;

[0071] The rejecting device 4 includes: a discharge receiving container 41 and a classification driving mechanism 42;

[0072] There are multiple arc ribs 12, and some adjacent two arc ribs 12 are separated by a rejection gap 13. When the feeding groove 111 is rotated to align with the rejection gap 13, the notch is exposed, and the input end of the discharge receiving container 41 is facing the rejection gap 13; the output end of the classification drive mechanism 42 is facing the rejection gap 13, and is used to drive the blind rivet 9 of the feeding groove 111 to move, so that the blind rivet 9 is output to the input end of the discharge receiving container 41 through the rejection gap 13.

[0073] like Figure 5 In this solution, the arc ribs 12 can be set as multiple sections of arc ribs 12, and rejection gaps 13 can be set between some of the arc ribs 12 to separate them, and the input end of the discharge receiving container 41 is oriented towards the rejection gap 13; in this way, when the feeding groove 111 is rotated to align with the rejection gap 13, the notch is exposed, and it passes through the input end of the discharge receiving container 41 in the form of a non-clamp 110; at this time, the classification drive mechanism 42 can be started, and the output end of the classification drive mechanism 42 can drive the blind rivet 9 of the feeding groove 111 to move, so as to pass through the notch of the feeding groove 111 and then move to the rejection gap 13, and then output to the input end of the discharge receiving container 41, so that the blind rivet 9 can be automatically output to the discharge receiving container 41.

[0074] In one embodiment, the classification drive mechanism 42 may be a mechanism for driving linear movement, such as a well-known linear drive device such as an air cylinder, an oil cylinder, or a manipulator.

[0075] Optimally, the discharge receiving container 41 includes: a qualified discharge cavity 411 and a defective discharge cavity 412;

[0076] The qualified discharge chamber 411 and the defective discharge chamber 412 are distributed on the outer edge of the feeding turntable 11, one of the rejection gaps 13 is linearly aligned with the input end of the qualified discharge chamber 411, and the other rejection gap 13 is linearly aligned with the input end of the defective discharge chamber 412, and each of the rejection gaps 13 corresponds to one of the classification drive mechanisms 42; the detection device 2 is communicatively connected to the classification drive mechanism 42.

[0077] This solution can divide the discharge receiving container 41 into: a qualified discharge chamber 411 and a defective discharge chamber 412; the detection device 2 is communicatively connected to the classification drive mechanism 42, and the classification drive mechanism 42 can receive the detection results of the detection device 2, and can mark the qualified blind rivets 9 and the unqualified blind rivets 9 according to the feedback of the detection device 2; after the blind rivet 9 rotates through the detection device 2, it can align with the rejection gap 13 of the qualified discharge chamber 411 or the rejection gap 13 of the defective discharge chamber 412 after moving the designed distance. For example, for a qualified blind rivet 9, it can move one unit less, and for an unqualified blind rivet 9, it can move one unit more; when an unqualified blind rivet 9 passes through the qualified discharge chamber 411, the classification drive mechanism 42 is not started; only when the unqualified blind rivet 9 moves to the input end aligned with the defective discharge chamber 412, or the qualified blind rivet 9 moves to the input end of the qualified discharge chamber 411, the classification drive mechanism 42 is started accordingly. In this way, the classification drive mechanism 42 can automatically classify qualified or unqualified blind rivets 9 into the qualified discharge cavity 411 and the defective discharge cavity 412 .

[0078] The communication connection method here refers to the communication between connected devices through signal transmission interaction, which can be divided into wired connection and wireless connection; wired connection includes conventional data cable connection; wireless connection includes conventional WiFi, Bluetooth, infrared, NFC, etc.

[0079] Optimally, the discharge receiving container 41 further includes: a re-detection discharge cavity 413;

[0080] The qualified discharge chamber 411, the defective discharge chamber 412 and the re-inspection discharge chamber 413 are distributed in sequence on the outer edge of the feeding turntable 11, or the defective discharge chamber 412, the qualified discharge chamber 411 and the re-inspection discharge chamber 413 are distributed in sequence on the outer edge of the feeding turntable 11; the input end of the re-inspection discharge chamber 413 is provided with a discharge baffle 414, and the discharge baffle 414 extends to the rotation range of one of the feeding grooves 111, and a falling distance 4140 is formed between the circular arc rib 12 and the discharge baffle 414, and the falling distance 4140 is vertically aligned with the input end of the re-inspection discharge chamber 413, and the circular arc rib 12 is used to guide the blind rivet 9 at the falling distance 4140 to detach from the feeding groove 111.

[0081] When the detection device 2 detects that the blind rivet 9 cannot be judged, it can be finally output to the re-detection discharge chamber 413. The blind rivet 9 in the re-detection discharge chamber 413 can be put back into the feeding device 3 for re-detection. This solution can also set up a re-detection discharge chamber 413 on the basis of the qualified discharge chamber 411 and the defective discharge chamber 412. The re-detection discharge chamber 413 is set at the end of the arrangement of multiple discharge chambers, for example, the qualified discharge chamber 411 and the re-detection discharge chamber 413 are distributed in sequence, or the defective discharge chamber 412, the qualified discharge chamber 411 and the re-detection discharge chamber 413 are distributed in sequence; the arc rib 12 extends to the rotation range of the feed turntable 11; and because the arc rib 12 is aligned with the discharge chamber A falling distance 4140 is formed between the baffles 414, and no clamp 110 is formed in the falling distance 4140. When the feeding groove 111 rotates and passes through the discharge baffle 414, the arc rib 12 can guide the blind rivet 9 of the feeding groove 111 to move along the length direction of the arc rib 12, so that the blind rivet 9 is separated from the feeding groove 111. The blind rivet 9 falls to the input end of the re-detection discharge chamber 413 under the action of gravity, thereby realizing automatic recovery of the blind rivet 9 to be re-measured.

[0082] Optimally, the classification drive mechanism 42 is a blowing device for blowing air toward the feeding groove 111 aligned with the rejection gap 13 , so that the blind rivets 9 in the feeding groove 111 are transferred to the input end of the discharge receiving container 41 through the rejection gap 13 .

[0083] The classification drive mechanism 42 of this scheme is preferably a blowing device, which can blow air into the feeding groove 111 of the removal gap 13, thereby driving the blind rivet 9 in the feeding groove 111 to move, and the blind rivet 9 is output to the input end of the discharge receiving container 41 through the removal gap 13. Thus, only when the blind rivet 9 moves to align with the qualified discharge cavity 411, the defective discharge cavity 412 or the re-inspection discharge cavity 413, the classification drive mechanism 42 will blow air to the feeding groove 111, otherwise the blind rivet 9 will only remain in the feeding groove 111, and the feeding groove 111 of the blind rivet 9 will continue to pass through the arc rib 12, and the clamp 110 will continue to limit the blind rivet 9 until it is transferred to the next qualified discharge cavity 411, the defective discharge cavity 412 and the re-inspection discharge cavity 413. In this way, the clamp 110 can keep the limit transition of the blind rivet 9 between the discharge cavity and the discharge cavity, and the transfer of the blind rivet 9 is stable. The blowing device is used as the classification drive mechanism 42 because the blowing device responds quickly, and the blind rivet 9 is promptly separated from the feeding groove 111, thereby improving the classification efficiency.

[0084] Optimally, the detection device 2 further includes: a height adjustment mechanism 24;

[0085] The height adjustment mechanism 24 includes: a height moving block 241 and a height adjustment track 242;

[0086] At least one of the rivet body top detection mechanism 21 , the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23 is installed on the height moving block 241 ; the height moving block 241 is limited to the height adjustment track 242 for lifting and lowering adjustment.

[0087] The height adjustment mechanism 24 can adjust the height of at least one of the rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 and the multi-angle detection mechanism 23. The height moving block 241 can be raised and lowered on the height adjustment track 242, driving the rivet body top detection mechanism 21, the nail core outer side detection mechanism 22 or the multi-angle detection mechanism 23 to rise and fall, thereby adjusting the detection height as needed to ensure that the blind rivet 9 is detected at the optimal detection height and improve the detection recognition.
