Description

Technical Field

[0001] This application relates to the technical field of sill beam judgment and detection equipment, and particularly relates to a multi-type sill beam judgment and detection equipment. Background Art

[0002] The automotive sill beam (also known as the sill panel) is a rigid crossbeam located at the lower side of the car door. When the side of the car collides, the sill beam can effectively prevent the car door from deforming, thereby enhancing the side protection performance. In new energy vehicles, the strength of the side sill beam plays a crucial role in protecting the battery. Therefore, the performance of the sill beam is an important guarantee for the safe driving of new energy vehicles. After the production of the automotive sill beam, rivet nuts, fittings, etc. need to be riveted, and it is necessary to detect whether there is any missing riveting or incorrect riveting after riveting.

[0003] After the production of the automotive sill beam, it is necessary to judge and detect. Currently, whether the sill beam is riveted or not is confirmed by the operator, which is inefficient, inaccurate and has no record. When there are many types of sill beams and left and right parts, it is impossible for personnel to confirm and control the types of sill beams and judge the left and right parts, and the workload is huge and the efficiency is low.

The sealing partition plate divides the lower piston chamber into two independent chambers. A first piston is movably sleeved in the lower piston chamber on one side of the sealing partition plate. A first connecting rod is fixedly connected to the middle of one side of the first piston. The end of the first connecting rod away from the first piston extends out of the outer side of the pipe cover and is fixedly connected with a linkage block.

[0017] 1. For a multi-type sill beam judgment and detection device provided by the present application, after the sill beam is conveyed by the conveyor line module to below the camera module in the frame module, first, the two outermost camera modules in the frame module take pictures and judge simultaneously to identify the product features of the sill beam, judge the type of the material and the left and right parts of the material. Then, all the camera modules detect all the surfaces of the sill beam simultaneously, so that multi-type sill beams can be detected for the presence or absence of multi-face nut riveting or missed riveting on the same device, and the model of the sill beam and whether it is a left part or a right part can be judged, and the detection records can be retained, which can effectively reduce costs, increase detection efficiency, improve detection accuracy, and have a small floor space.

[0018] 2. For a multi-type sill beam judgment and detection device provided by the present application, by arranging at least three jaw assemblies, when one of the jaw assemblies clamps and flips the sill beam and just lies between the sill beam and the camera module, the jaw assembly automatically flips and separates from the sill beam to avoid blocking the camera module from visually detecting the surface of the sill beam, thereby improving the accuracy of the surface detection result of the sill beam. At the same time, the other jaw assemblies keep the sill beam clamped and fixed, thereby ensuring the stable detection of the surface of the sill beam. Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1, as Figures 1-3 , a multi-type sill beam judgment and detection device, including a frame module 1. A conveyor line module 2 is provided in the middle below the frame module 1, and the conveyor line module 2 penetrates the frame module 1. A plurality of camera modules 3 are provided at the top of the inner cavity of the frame module 1. The number of camera modules 3 is not less than two, and a plurality of camera modules 3 are horizontally arranged at equal intervals in the inner cavity of the frame module 1 and above the conveyor line module 2. Fixture modules 4 are provided on both sides of the feeding end of the conveyor line module 2. The sill beam placed on the conveyor line module 2 is positioned through the fixture module 4. After the conveyor line module 2 conveys the sill beam below the camera module 3 in the frame module 1, the camera module 3 is used to detect the surface of the sill beam.

[0033] A first light shield 5 is provided on the frame module 1 above the conveyor line module 2 and outside the camera module 3, and a second light shield 6 is further provided at the bottom of the frame module 1 on both sides of the conveyor line module 2 and directly below the camera module 3. A third light shield 7 is provided on the conveyor line module 2 directly below the camera module 3. Through the light shielding effects of the first light shield 5, the second light shield 6, and the third light shield 7, external light is prevented from interfering with the visual detection by the camera module 3.

[0034] On both sides of the conveyor line module 2, a lifting mechanism 8 is fixedly installed. On both sides of the frame module 1, a rotary drive device 9 is respectively fixedly installed, and the rotary drive device 9 is located above the conveyor line module 2. After the conveyor line module 2 conveys the sill beam to the lower part of the camera module 3, the lifting mechanism 8 on both sides of the conveyor line module 2 jacks up the sill beam. The rotary drive device 9 on both sides of the frame module 1 clamps both ends of the sill beam and drives the sill beam to rotate in sequence. The camera module 3 is used to detect each surface of the sill beam in sequence. After the detection is completed, the rotary drive device 9 rotates and resets. Then the lifting mechanism 8 transfers the sill beam. After the transfer, the sill beam, under the control of the lifting mechanism 8, drops onto the conveyor line module 2 and is conveyed by the conveyor line module 2 to the next working station.

[0035] Please refer to Figure 1 and Figure 4 , the rotary drive device 9 includes a mounting plate 901 fixedly installed on the frame module 1. On the outer side of the mounting plate 901, a servo motor 902 is fixedly installed. The output rotating shaft of the servo motor 902 extends to the inner side of the mounting plate 901 and is fixedly connected with a passive rotating plate 903. On the side of the passive rotating plate 903 away from the mounting plate 901, two flipping drive cylinders 10 are fixedly installed, and on the output rotating shafts of the two flipping drive cylinders 10, clamping jaw assemblies 11 are respectively fixedly installed. By respectively driving the output rotating shafts of the two flipping drive cylinders 10 to drive the two clamping jaw assemblies 11 to rotate, the two clamping jaw assemblies 11 are controlled to flip and clamp one end of the sill beam.

[0036] The clamping jaw assembly 11 includes a flipping linkage block 101 fixedly sleeved on the output rotating shaft of the flipping drive cylinder 10. At one end of the flipping linkage block 101 away from the output rotating shaft of the flipping drive cylinder 10, a cross bar 111 is fixedly connected. At both ends of the side surface of the cross bar 111, positioning rods 112 are respectively fixedly connected. At the ends of the two positioning rods 112 away from the cross bar 111, clamping blocks 113 are respectively fixedly installed. A reinforcing rib 114 is fixedly installed between the two positioning rods 112. Through the structural design of arranging the positioning rods 112 at both ends of the side surface of the cross bar 111, the clamping jaw assembly 11 can grasp one surface of the sill beam, so as to clamp the sill beam and drive the sill beam to flip.

[0037] On the front and back bottoms of the frame module 1, light-shielding curtains 29 are respectively fixedly installed, and the light-shielding curtains 29 are located above the conveyor line module 2. Through the setting of the light-shielding curtains 29, it does not affect the entry and exit of the sill beam on the conveyor line module 2 into and out of the interior of the frame module 1, and shields the gap between the frame module 1 and the conveyor line module 2 (the space for the sill beam to move through), thereby improving the light-shielding effect and further improving the accuracy of the visual detection result.

[0038] Please refer to 1- Figure 5, during use, load materials at one end of the conveyor line module 2. After loading, position the sill beam through the fixture modules 4 on both sides of the conveyor line module 2 to adapt to the lengths of different sill beams. After the sill beam is positioned, the conveyor line module 2 transports the sill beam to the position directly below the camera module 3 inside the rack module 1. Start the lifting mechanisms 8 on both sides of the conveyor line module 2 to lift the sill beam to the height of the rotary drive device 9. Then control the two rotary drive devices 9 to flip and grasp and clamp both ends of the sill beam respectively. First, the two outermost camera modules 3 inside the rack module 1 take pictures simultaneously to judge and identify the product features of the sill beam, so as to judge the type of the material and the left and right parts of the material (such as Figure 6 the state shown, and when the total number of camera modules 3 is set to four), then control each camera module 3 inside the rack module 1 to take pictures simultaneously to identify the surface of the sill beam. Then control the rotary drive device 9 to drive the sill beam to flip, and each camera module 3 inside the rack module 1 takes pictures of the next surface of the sill beam simultaneously for inspection. Repeat this process until all surfaces of the sill beam are visually inspected and corresponding markings are made. If NG, then the sill beam is transported by the conveyor line module 2 to the next station to stamp NG for manual identification. Repeat the above steps. When the sill beam reaches the last position of the conveyor line, the sensor senses and stops the transportation, and manual unloading is performed.

[0039] Embodiment 2, on the basis of Embodiment 1, the difference from Embodiment 1 is the specific structure of the rotary drive device 9. Please refer to Figures 7-9 . At least three positioning double tubes 12 are arranged on the outer side of the passive rotating plate 903. The number of positioning double tubes 12 is based on the number of surfaces of the sill beam. If the number is greater than four, the number of positioning double tubes 12 can be set to four or more. Two piston chambers are arranged up and down inside the positioning double tube 12, namely the upper piston chamber and the lower piston chamber. And a through hole 121 is opened in the middle of the side of the positioning double tube 12 away from the passive rotating plate 903, and the upper piston chamber and the lower piston chamber are communicated through the through hole 121. Pipe caps 13 are respectively fixedly installed at both ends of the positioning double tube 12. A sealing partition 14 is fixedly installed in the middle of the lower piston chamber. The sealing partition 14 divides the lower piston chamber into two independent chambers. A first piston 15 is movably sleeved inside the lower piston chamber on one side of the sealing partition 14. A first connecting rod 16 is fixedly connected to the middle of one side of the first piston 15. The end of the first connecting rod 16 away from the first piston 15 extends out of the outer side of the pipe cap 13 and is fixedly connected to a linkage block 17. One end of the linkage block 17 is fixedly connected to a rack 18.

[0040] On the outer side of one of the tube caps 13, a sealing cover 19 located outside the toothed rod 18 is fixedly installed. A rotating shaft 20 is movably sleeved inside the sealing cover 19. A gear 201 is fixedly sleeved in the middle of the rotating shaft 20. The outer side of the gear 201 meshes with the tooth grooves on the toothed rod 18. Both ends of the rotating shaft 20 extend out of the outer side of the sealing cover 19 and are connected to the jaw assembly 11. One end of each of the two cross bars 111 away from the rotating shaft 20 is fixedly connected to a positioning rod 112, and one end of each of the two positioning rods 112 away from the cross bar 111 is fixedly connected to a clamping block 113. Inside the other tube cap 13, a first electromagnet 21 is fixedly installed, and the first electromagnet 21 is located inside the lower piston chamber. A sliding block 22 located on the other side of the partition plate 14 is movably sleeved inside the lower piston chamber. A first magnetic ring 23 is fixedly installed on the side of the sliding block 22 facing the first electromagnet 21. A second connecting rod 24 is fixedly connected between the sliding block 22 and the first piston 15. A return spring 25 is arranged outside the first connecting rod 16 and is located between the first piston 15 and the tube cap 13.

[0041] A second piston 26 is movably sleeved inside the upper piston chamber. A second magnetic ring 27 is fixedly installed on the side of the second piston 26 away from the through hole 121. A second electromagnet 28 is fixedly installed on the mounting plate 901 and is directly above the output rotating shaft of the servo motor 902. The second electromagnet 28 corresponds to the position of the second magnetic ring 27 in the uppermost positioning double tube 12. The chamber on one side of the second piston 26 in the upper piston chamber and the chamber on one side of the first piston 15 in the lower piston chamber are communicated through the through hole 121, and the communicating chamber is filled with a liquid (the liquid can be water or hydraulic oil).

[0042] During use, the first electromagnet 21 is energized to generate a magnetic repulsive force on the first magnetic ring 23, pushing the sliding block 22 to drive the second connecting rod 24, the first piston 15, the first connecting rod 16, the linkage block 17 and the rack 18 to move to the right. By using the meshing effect between the rack 18 and the gear 201, the gear 201 drives the rotating shaft 20 and the jaw assembly 11 to flip, thereby clamping one end of the sill beam. At the same time, the second piston 26 in the upper piston chamber moves to the left under the action of liquid pressure. When one of the jaw assemblies 11 is directly above the sill beam, this jaw assembly 11 will form an occlusion between the sill beam and the camera module 3. At this time, the second magnetic ring 27 is exactly located on one side of the second electromagnet 28. The second electromagnet 28 is energized to generate a magnetic repulsive force on the second magnetic ring 27, pushing the second magnetic ring 27 to drive the second piston 26 to move to the right, and pressing the liquid in the upper piston chamber back into the lower piston chamber through the through hole 121. Cooperating with the elastic force of the return spring 25, overcoming the magnetic repulsive force of the first electromagnet 21 on the first magnetic ring 23, pushing the first piston 15 to pull the first connecting rod 16, the linkage block 17 and the rack 18 to move to the left, causing the first electromagnet 21 to rotate in the reverse direction, and then causing the jaw assembly 11 to flip and reset in the reverse direction, so as not to form an occlusion between the sill beam and the camera module 3. At the same time, the other jaw assemblies 11 maintain the clamping state of the sill beam, so that the surface of the sill beam can be comprehensively detected. Moreover, the structural design of the small electromagnet has lower cost and energy consumption compared with the method of setting multi-station shooting.

[0043] Embodiment 3. Please refer to Figure 10 , on the basis of Embodiment 1, different from Embodiment 1, the number of clamping blocks 113 on the positioning rod 112 is not less than two. The clamping blocks 113 are arranged equidistantly on the positioning rod 112, and an elastic band 115 is fixedly connected between the clamping blocks 113 between the two positioning rods 112. When clamping a sill beam with an irregular surface, the elastic band 115 is stretched to fit on the surface of the sill beam, thereby improving the clamping effect on the sill beam with an irregular surface.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
