[0053] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0054] When conducting missing rivet detection, the existing detection method is for the staff to use a marker to mark the rivet position to check whether the product has missing rivets. However, this detection method is not only extremely inefficient, but the detection effect will gradually decrease as the working time increases, so that defective products with missing rivets will still flow into the market.

[0055] Based on this, please refer to Figures 1 to 3 A missing rivet detection device is proposed, comprising a support plate 1 and a first profiling seat 2 arranged on the support plate 1, and a clamping device 3 and a detection assembly 4 are also provided on the support plate 1; the clamping end of the clamping device 3 is arranged opposite to the positioning surface of the first profiling seat 2; the detection assembly 4 comprises a lifting device 41 and a switch member 42; the switch member 42 is connected to the movable end of the lifting device 41, and the clamping device 3 and the lifting device 41 are electrically connected to the switch member 42 respectively; the lifting device 41 can drive the switch member 42 to rise and fall and contact the end to be detected of the material.

[0056] It can be understood that the missing rivet detection device of the present invention utilizes the feature that there is a raised structure on the surface of the material after riveting. After the material to be detected is fixed on the first profiling seat 2 by the clamping device 3, the jacking device 41 is started to drive the switch member 42 to move toward the end of the material to be detected. If the switch member 42 contacts the raised structure to start the switch member 42, it is proved that the material is qualified, and the clamping device 3 and the detection component 4 are further triggered by the switch member 42, so that the clamping device 3 and the detection component 4 are reset to prepare for the next detection; otherwise, the material quality is unqualified, and because the switch member cannot be triggered, the material cannot be smoothly riveted, thereby prompting the staff to perform related rework operations; compared with the existing missing rivet detection form, the missing rivet detection device of the present invention adopts a purely mechanical structure to perform missing rivet detection work, so as to achieve automatic, efficient and accurate detection effect; at the same time, due to the characteristic that the material cannot be automatically unlocked due to missing rivets, the risk of defective products of missing rivets entering the market can be completely avoided.

[0057] In some embodiments, the clamping device 3 includes a driving device 31 and a clamping assembly; the clamping assembly is connected to the movable end of the driving device 31; the driving device 31 can drive the clamping assembly to rotate around the X-axis; the positioning surface of the first profiling seat 2 is located within the rotation path of the clamping end of the clamping assembly; the driving device 31 includes a driving member and a support rod; the support rod is connected to the movable end of the driving member; two switch members 42 are provided, and the two switch members 42 are respectively provided at both ends of the length direction of the support rod. This design makes specific modifications to the composition structure of the clamping device 3. The method of driving the clamping assembly through the driving device 31 to achieve flip clamping can not only realize automatic clamping, achieve the effect of releasing labor and saving labor costs, but also effectively improve the efficiency of material disassembly and assembly, thereby improving the overall production efficiency.

[0058] In some embodiments, the clamping assembly includes a support frame 32, a flip rod 33 and a clamping member 34; one end of the flip rod 33 is hinged to the movable end of the driving device 31, and the other end of the flip rod 33 is connected to the clamping member 34; the middle section of the flip rod 33 is hinged to the fixed end of the driving device 31 through the support frame 32; and the positioning surface of the first profiling seat 2 is located within the rotation path of the clamping end of the clamping member 34. The design makes specific modifications to the composition structure of the clamping assembly, so that the clamping assembly can rotate around the X-axis direction, thereby providing structural support for fixing the material on the first profiling seat 2, and preventing the lifting device 41 from moving synchronously with the lifting device 41 due to the looseness of the material when the switch member 42 is driven close to the material, so that the protruding structure at the material riveting position cannot trigger the switch member 42 to reset the clamping device 3 and the detection assembly 4, resulting in the qualified product being misjudged as a defective product, thereby wasting extra time.

[0059] In some embodiments, the support plate 1 is also provided with a solenoid valve 5, a first start switch 6 and a second start switch 7; the lifting device 41 and the driving device 31 are both cylinders; the lifting device 41 and the driving device 31 are both connected to the valve body of the corresponding solenoid valve 5; the control end of the solenoid valve 5 corresponding to the lifting device 41 and the control end of the solenoid valve 5 corresponding to the driving device 31 are both electrically connected to the switch 42; the control end of the solenoid valve 5 corresponding to the lifting device 41 and the control end of the solenoid valve 5 corresponding to the driving device 31 are respectively electrically connected to the first start switch 6 and the second start switch 7. This design provides a pneumatic control solution for the missing rivet detection device of the utility model. Compared with the traditional pure circuit control solution, while ensuring the normal operation of the missing rivet detection device, it can also effectively reduce the equipment manufacturing cost of the missing rivet detection device, thereby improving the overall cost performance.

[0060] In some embodiments, a pressure regulating valve 8 is further provided on the support plate 1; the valve body of the pressure regulating valve 8 is connected to the valve body of the solenoid valve 5. The pressure regulating valve 8 can facilitate the staff to adjust the air pressure provided by the peripheral air source device according to actual needs, so as to achieve the function of controlling the running speed of the jacking device 41 and the driving device 31, and avoid problems such as damage to materials due to excessive running speed, or affecting work efficiency due to excessive running speed.

[0061] In some embodiments, when the number of switch elements 42 is more than one, all switch elements 42 are connected in series to form a switch assembly; the control end of the solenoid valve 5 corresponding to the lifting device 41 and the control end of the solenoid valve 5 corresponding to the driving device 31 are respectively electrically connected to the switch element 42. When the material to be detected has multiple riveting points, in order to ensure the detection effect and avoid the problem that some points of the material after detection are still not riveted, all switch elements 42 are connected in series to form a switch assembly, that is, the clamping device 3 and the detection assembly 4 can only be reset when all switch elements 42 are triggered, so that the staff can remove the material.

[0062] In some embodiments, at least two auxiliary positioning blocks 9 are further provided on the support plate 1 in the X-axis direction; the first profiling seat 2 is arranged between any two adjacent auxiliary positioning blocks 9; the positioning surface of the first profiling seat 2 and the positioning surfaces of all the auxiliary positioning blocks 9 are arranged toward the same side of the Z-axis direction; the positioning surface of the first profiling seat 2 and the positioning surfaces of all the auxiliary positioning blocks 9 constitute a virtual positioning surface. When the supported material is long or large in size, the effective positioning area of ​​the missing rivet detection device of the utility model can be increased through the cooperation between the auxiliary positioning block 9 and the first profiling block, thereby helping to improve the stability of the material during the detection process.

[0063] In some embodiments, the distance between the positioning surface of the first profiling seat 2 and the support plate 1 is smaller than the distance between the positioning surface of the auxiliary positioning block 9 and the support plate 1. Specifically, the distance between the positioning surface of the first profiling seat 2 and the support plate 1, and the distance between the positioning surface of the auxiliary positioning block 9 and the support plate 1 can be adjusted according to the profile of the material to be detected, that is, the virtual positioning surface formed by the first profiling seat 2 and the auxiliary positioning block 9 can be an arc surface or a plane; and the arc-shaped positioning surface can be a concave surface with high ends and low middle, or a convex surface with low ends and high middle; the virtual positioning surface can even be an irregular wave shape; this design can fully improve the adaptability of the missing rivet detection device of the utility model, so that it can detect a variety of materials, thereby expanding the overall scope of use.

[0064] In some embodiments, in the X-axis direction, a limit block 10 is further provided on the support plate 1; the limit block 10 is arranged outside the virtual positioning surface formed by the positioning surface of the first profiling seat 2 and the positioning surfaces of all the auxiliary positioning blocks 9, and the limit end of the limit block 10 is arranged toward the first profiling seat 2. This design has a positioning effect on the material in the X-axis direction, that is, when the material is placed on the virtual positioning surface formed by the positioning surface of the first profiling seat 2 and the positioning surfaces of all the auxiliary positioning blocks 9, the end surface of the material is again brought into contact with the limit surface of the limit block 10, and the material can be accurately moved to the specified position, thereby ensuring that the switch member 42 can accurately contact the protruding structure at the material riveting position during detection, so that qualified materials can be removed smoothly.
