Description

Technical Field

[0001] This application relates to the field of visual inspection equipment for door sill beams, and more particularly to a CCD inspection device for the left and right door sill beams of new energy vehicles. Background Technology

[0002] The door sill beam, also known as the side sill or door sill assembly, is a key longitudinal structural component located below the door and connecting the two sides of the bottom of the vehicle body. It is usually made of high-strength aluminum alloy or hot-formed steel. Its structure needs to be connected to the battery frame to prevent the bottom plate from deforming and squeezing the battery module due to side impact, thereby reducing the risk of fire.

[0003] In the current production of door sill beams, the surface and left and right components of the door sill beams need to be inspected to ensure that the products are qualified and can be installed on new energy vehicles. However, due to the weight of the door sill beams, manual handling is inefficient, and if the inspection fails, the machine needs to be stopped for processing, which further reduces efficiency. To address this, a CCD inspection device for the left and right components of door sill beams for new energy vehicles is provided to improve inspection efficiency. Summary of the Invention

The NG position lifting cylinder drives the material support plate to lift the detected unqualified sill beam until it is separated from the conveying device.

[0009] The material lifting cylinder installed at the material feeding end of the conveying device lifts the qualified sill beam until it is separated from the conveying device.

[0010] Furthermore, the lifting device includes a detection lifting cylinder fixedly installed on the frame. The piston shaft of the detection lifting cylinder is fixedly connected to a material support block, and the bottom of the material support block is provided with guide shafts located on both sides of the piston shaft.

A second L-shaped plate is also fixedly mounted on the moving block. A longitudinally arranged Z-axis drive cylinder is fixedly mounted on the second L-shaped plate. A longitudinal moving plate is fixedly connected to the piston shaft at the bottom of the Z-axis drive cylinder.

[0012] Furthermore, the horizontal positioning block is equipped with a sensor.

[0013] Furthermore, a limit baffle is also fixedly installed on the side of the Y-axis drive cylinder.

[0014] Furthermore, the first L-shaped plate is rotatably mounted on one side of the positioning mounting plate, and the rotation of the three-axis clamping rotation device is driven by a servo motor mounted on the positioning mounting plate. The positioning mounting plate is fixedly mounted on two support columns, and the two support columns are fixedly mounted on the frame.

[0015] Furthermore, a passive rotating plate is mounted on the side of the positioning mounting plate via bearings. A linkage disc is fixedly mounted on the side of the first L-shaped plate. A linkage shaft is fixedly connected to the middle of the side of the linkage disc away from the first L-shaped plate. A brake disc is fixedly connected to one end of the linkage shaft. A servo motor is fixedly connected to the middle of the side of the brake disc away from the linkage shaft. Brakes are respectively provided on the outer edges of both sides of the brake disc. One side of the brake is fixedly connected to the side of the passive rotating plate via several fixed shafts. Two limit mounting plates are fixedly mounted below the positioning mounting plate. A rotation reset holding device is fixedly mounted on each of the two limit mounting plates. Limit shafts are fixedly mounted on the outer edges of both sides of the brake. Connecting ropes are fixedly connected to the limit shafts. The ends of the two connecting ropes away from the limit shafts extend into the interior of the rotation reset holding device.

[0016] Furthermore, the rotational reset holding device includes a limiting tube fixedly installed on a limiting mounting plate. Cover plates are fixedly installed on the upper and lower sides of the limiting tube, and an electromagnet is fixedly installed on the bottom cover plate. A sliding block is movably installed inside the limiting tube. An iron block located directly above the electromagnet is fixedly installed at the bottom of the sliding block.

[0020] 1. This application provides a CCD inspection device for the left and right sill beams of new energy vehicles. The sill beams are transported to the vision inspection box by a material conveying device. The sill beams are clamped and rotated by a three-axis clamping and rotating device. The vision inspection system set at the top of the inner cavity of the vision inspection box is used to visually inspect whether the surface of the sill beams is qualified, thereby reducing the efficiency of manual handling and improving the inspection efficiency.

[0021] 2. A visual inspection system is installed at the top of the inner cavity of the visual inspection box to inspect the left and right parts of the door sill beam. Based on the inspection results, it is convenient for the material handlers to separate and place the products.

[0022] 3. By using the NG position lifting cylinder set on the side of the vision inspection box facing the material feeding end of the conveying device, the NG position lifting cylinder is used to lift the detected unqualified sill beams to separate them from the conveying device, which makes it convenient for workers to unload and repair them separately, while not affecting the subsequent conveying device to continue to transport sill beams for inspection, thus further improving the inspection efficiency of sill beams.

[0040] 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.

[0041] Example 1, as Figures 1-2 A CCD inspection device for the left and right door sill beams of new energy vehicles includes a frame 1, a material conveying device 2 on the frame 1, a vision inspection box 3 mounted on the frame 1 in the middle of the material conveying device 2, and two marking machines 4 on the side of the vision inspection box 3 facing the material conveying device 2. After the door sill beam is fed from the feeding side of the material conveying device 2, the material conveying device 2 drives the door sill beam to be conveyed directly below the marking machines 4, and the marking machines 4 are used to mark the door sill beam.

[0042] The top of the inner cavity of the vision inspection box 3 is equipped with a vision inspection system (not shown in the figure). When the material conveying device 2 transports the marked sill beam into the interior of the vision inspection box 3, the light-blocking effect of the vision inspection box 3, together with the camera lens in the vision inspection system, is used to visually inspect the sill beam that has passed the standard.

[0043] Please refer to the details. Figure 1 and Figure 3Two lifting devices are fixedly installed on the frame 1 on both sides of the conveying device 2. The two lifting devices are located below the camera lens of the vision inspection system in the inner cavity of the vision inspection box 3. The lifting device includes a detection lifting cylinder 501 fixedly installed on the frame 1. The piston shaft of the detection lifting cylinder 501 is fixedly connected to a material support block 502. The bottom of the material support block 502 is provided with guide shafts 503 located on both sides of the piston shaft. The guide shafts 503 are movably connected to the frame 1. When the conveying device 2 conveys the sill beam to the area below the camera lens of the vision inspection system in the inner cavity of the vision inspection box 3, the detection lifting cylinders 501 in the two lifting devices drive the piston shaft to push the guide shafts 503, so that the two guide shafts 503 on both sides of the conveying device 2 support the two ends of the sill beam and move them upward.

[0044] Please see Figure 1 , Figures 4-8 Inside the frame 1, two three-axis clamping and rotating devices 6 are also fixedly installed. The two three-axis clamping and rotating devices 6 are respectively located on both sides of the two lifting devices. The three-axis clamping and rotating device 6 includes a first L-shaped plate 601, which is rotatably mounted on one side of the positioning mounting plate 7. The rotation of the three-axis clamping and rotating device 6 is driven by a servo motor mounted on the positioning mounting plate 7. The positioning mounting plate 7 is fixedly mounted on two support columns 8, and the two support columns 8 are fixedly mounted on the frame 1. The positioning mounting plate 7 and the support columns 8 support the three-axis clamping and rotating device 6.

[0045] An X-axis drive cylinder 602 is fixedly installed on the first L-shaped plate 601. A moving block 603 is fixedly connected to the piston shaft of the X-axis drive cylinder 602. A horizontally positioned Y-axis drive cylinder 604 is fixedly installed on the moving block 603. A horizontal moving block 605 is fixedly connected to the piston shaft of the Y-axis drive cylinder 604. A horizontal positioning block 606 is fixedly installed on the moving block 603 on the side away from the horizontal moving block 605, and the horizontal positioning block 606 corresponds to the horizontal moving block 605. A sensor is provided on the horizontal positioning block 606. After the lifting device lifts the sill beam to the height of the horizontal moving block 605 and the horizontal positioning block 606, the X-axis drive cylinder 602 drives the piston shaft to push the moving block 605. The moving block 603 moves, causing the horizontal positioning block 606 and the horizontal moving block 605 to enter the interior of one end of the sill beam. Then, the Y-axis drive cylinder 604 drives the piston shaft to push the horizontal moving block 605 away from the horizontal positioning block 606, so that the horizontal moving block 605 and the horizontal positioning block 606 respectively abut against the inner walls on both sides of one end of the sill beam. At this time, the sensor set on the horizontal moving block 605 detects that the horizontal moving block 605 and the horizontal positioning block 606 have clamped the sill beam together. Then, the detection lifting cylinder 501 in the lifting device drives the piston shaft to move the material support block 502 downward, separating it from the sill beam and maintaining a sufficient distance so as not to affect the subsequent rotation of the sill beam by the three-axis clamping and rotating device 6.

[0046] A second L-shaped plate 607 is also fixedly installed on the moving block 603. A longitudinally arranged Z-axis drive cylinder 608 is fixedly installed on the second L-shaped plate 607. The piston shaft at the bottom of the Z-axis drive cylinder 608 is fixedly connected to a longitudinal moving plate 609. When the X-axis drive cylinder 602 drives the piston shaft to push the moving block 603 toward the threshold beam, one end of the longitudinal moving plate 609 also moves to the inside of one end of the threshold beam. After the horizontal moving block 605 and the longitudinal moving plate 609 clamp the inner walls of both sides of one end of the threshold beam, the Z-axis drive cylinder 608 drives the piston shaft to move the longitudinal moving plate 609 upward, so that the top of the longitudinal moving plate 609 connects with the top inside of one end of the threshold beam. Together with the bottom of the horizontal moving block 605 and the horizontal positioning block 606, they connect with the bottom inner wall of one end of the threshold beam, thereby limiting the threshold beam at one end of the threshold beam. During the period when the three-axis clamping and rotating device 6 drives the threshold beam to rotate for testing, the threshold beam will not loosen and affect the accuracy of the test results.

[0047] A limiting baffle 9 is also fixedly installed on the side of the Y-axis drive cylinder 604. When the X-axis drive cylinder 602 drives the moving block 603 to move toward the sill beam, the limiting baffle 9 abuts against one end of the sill beam. Then, the moving block 603 drives the piston shaft to move the horizontal moving block 605. The Z-axis drive cylinder 608 drives the piston shaft to move the longitudinal moving plate 609. The horizontal moving block 605, the horizontal positioning block 606 and the longitudinal moving plate 609 are used to fix the sill beam inside one end of the sill beam, without affecting the visual inspection of the sill beam surface.

[0048] Please continue reading. Figures 1-2 The frame 1 is fixedly installed with NG position lifting cylinders 10 located on both sides of the conveying device 2. The piston shaft of the NG position lifting cylinder 10 is fixedly installed with a material support plate. The two NG position lifting cylinders 10 are located on the side of the vision inspection box 3 away from the marking machine 4. When the vision inspection system in the vision inspection box 3 detects that the sill beam is unqualified (NG), the conveying device 2 moves the unqualified sill beam to the NG position lifting cylinder 10. The NG position lifting cylinder 10 lifts the unqualified sill beam and separates it from the conveying device 2, which does not affect the subsequent unloading of qualified sill beams and facilitates workers to unload and rework.

[0049] The frame 1 is equipped with two unloading lifting cylinders 11 located at the unloading end of the conveying device 2, and the frame 1 is equipped with an indicator light 12 located at the unloading lifting cylinder 11. When a qualified threshold beam is detected by the visual inspection system in the visual inspection box 3 and is conveyed to the unloading lifting cylinder 11 by the conveying device 2, the unloading lifting cylinder 11 lifts the qualified threshold beam without affecting the movement of the subsequent threshold beams driven by the conveying device 2. At the same time, when the detected threshold beam is a left piece, the indicator light 12 on the left side of the conveying device 2 lights up, reminding the unloading personnel to place the threshold beam of the left piece into the finished product box where the threshold beam of the left piece is located. When the detected threshold beam is a right piece, the indicator light 12 on the right side of the conveying device 2 lights up, reminding the unloading personnel to place the threshold beam of the left piece into the finished product box where the threshold beam of the right piece is located.

[0050] When using, such as Figures 1-9 After the sill beam is loaded onto the conveying device 2, the conveying device 2 moves the sill beam to below the marking machine 4, where the marking machine 4 marks the sill beam. Then, the conveying device 2 moves the sill beam into the visual inspection box 3. The lifting cylinder 501 drives the piston shaft to move the material support block 502 upward, lifting the sill beam until it separates from the conveying device 2. Then, the X-axis drive cylinder 602 in the three-axis clamping and rotating device 6 drives the piston shaft to move the moving block 603, so that the limiting baffle 9 abuts against one end of the sill beam. At this time, the horizontal moving block 605, the horizontal positioning block 606, and the longitudinal moving plate 609 are located inside one end of the sill beam. Then, the Y-axis drive cylinder 604 on the moving block 603 drives the piston shaft to move the horizontal moving block 605, the horizontal positioning block 606, and the longitudinal moving plate 609. The moving block 605 moves away from the horizontal positioning block 606, causing the horizontal moving block 605 and the horizontal positioning block 606 to abut against the inner walls on both sides of one end of the sill beam. The Z-axis drive cylinder 608, which is longitudinally arranged on the second L-shaped plate 607, drives the piston shaft to move the longitudinal moving plate 609 upward, so that the top of the longitudinal moving plate 609 abuts against the top inner wall of one end of the sill beam. At the same time, the bottom of the horizontal moving block 605 and the horizontal positioning block 606 contacts the bottom inner wall of one end of the sill beam, thereby clamping inside one end of the sill beam and fixing one end of the sill beam. When the sensor on the horizontal moving block 605 detects that the sill beam is fixed, the detection lifting cylinder 501 drives the piston shaft to move the material support block 502 downward and separate it from the sill beam.

[0051] Then, the camera lens of the vision inspection system inside the vision inspection box 3 performs visual inspection on the upper surface of the sill beam. Then, the sill beam is rotated by the three-axis clamping and rotating device 6, and each surface of the sill beam is visually inspected in turn. After the visual inspection is completed, the detection lifting cylinder 501 drives the piston shaft to move the material support block 502 upward, so that the material support block 502 supports the sill beam. Then, the Z-axis driving cylinder 608 drives the piston shaft to move the longitudinal moving plate 609 downward. The Y-axis driving cylinder 604 drives the piston shaft to move the horizontal moving block 605 toward the horizontal positioning block 606. Then, the X-axis driving cylinder 602 drives the piston shaft to pull the moving block 603 away from the sill beam until the horizontal moving block 605, the horizontal positioning block 606 and the longitudinal moving plate 609 are separated from the sill beam. The detection lifting cylinder 501 drives the piston shaft to move the material support block 502 downward until the sill beam moves back to the material conveying device 2. The material conveying device 2 drives the sill beam to continue moving.

[0052] When a defective door sill beam is detected, it moves to the NG position lifting cylinder 10, which then lifts and locks the defective door sill beam. The beam is then manually unloaded for rework. When a qualified door sill beam is detected, and the detected door sill beam is a left piece, the indicator light 12 on the left side of the conveying device 2 illuminates, reminding the unloading personnel to place the left piece's door sill beam into the finished product box containing the left piece's door sill beam. When a right piece's door sill beam is detected, the indicator light 12 on the right side of the conveying device 2 illuminates, reminding the unloading personnel to place the left piece's door sill beam into the finished product box containing the right piece's door sill beam.

[0053] Example 2, as Figure 11-15 Based on Embodiment 1, a passive rotating plate 13 is mounted on the side of the positioning mounting plate 7 via bearings. A linkage disc 14 is fixedly mounted on the side of the first L-shaped plate 601. A linkage shaft 15 is fixedly connected to the middle of the side of the linkage disc 14 away from the first L-shaped plate 601. A brake disc 16 is fixedly connected to one end of the linkage shaft 15. A servo motor is fixedly connected to the middle of the side of the brake disc 16 away from the linkage shaft 15. Brakes 17 are respectively provided on the outer edges of both sides of the brake disc 16. One side of the brake 17 is fixedly connected to the side of the passive rotating plate 13 via several fixed shafts. Two limit mounting plates 18 are fixedly mounted below the positioning mounting plate 7. Rotation reset holding devices 19 are fixedly mounted on the two limit mounting plates 18 respectively. Limit shafts 20 are fixedly mounted on the outer edges of both sides of the brake 17. Connecting ropes 21 are fixedly connected to the limit shafts 20. The connecting ropes 21 are made of non-elastic soft rope. The ends of the two connecting ropes 21 away from the limit shafts 20 respectively extend into the interior of the rotation reset holding devices 19.

[0054] The rotary reset holding device 19 includes a limiting tube 191 fixedly installed on the limiting mounting plate 18. Cover plates 192 are fixedly installed on the upper and lower sides of the limiting tube 191 respectively. An electromagnet 193 is fixedly installed on the bottom cover plate 192. A sliding block 194 is movably installed inside the limiting tube 191. An iron block 195 located directly above the electromagnet 193 is fixedly installed at the bottom of the sliding block 194. A tensioning block 196 is fixedly installed at the top of the sliding block 194. One end of the connecting rope 21 away from the limiting shaft 20 is fixedly connected to the tensioning block 196. A spring 197 is provided at the top of the sliding block 194 between another cover plate 192. The spring 197 is movably fitted on the outside of the connecting rope 21.

[0055] In the initial state, the elastic force of the springs 197 inside the two limiting tubes 191, combined with the pulling force of the connecting rope 21, causes the two limiting shafts 20 on the passive rotating plate 13 to be positioned exactly on both sides, i.e. Figure 12 As shown, when the servo motor drives the output shaft to rotate the first L-shaped plate 601, it in turn rotates the sill beam to perform visual inspection on each surface of the sill beam. Simultaneously, it rotates the linkage disc 14 and the brake disc 16. When the servo motor stops rotating, the brake 17 activates simultaneously. The brake pads inside the brake 17 instantly adhere to both sides of the brake disc 16. Under the action of rotational inertia, the brake disc 16 drives the brake 17 and the passive rotating plate 13 to rotate to a stop. Then, the electromagnets 193 in the two limit tubes 191 are simultaneously energized, generating a magnetic attraction force on the iron block 195. This causes the iron block 195 in the two limit tubes 191 to magnetically adhere to the electromagnets 193, thereby restoring the passive rotating plate 13, brake disc 16, and brake 17 to their original positions. Figure 12 As shown, even if the brake disc 16 returns to the position where the servo motor stops rotating and remains there, the angle control accuracy when the servo motor drives the three-axis clamping rotating device 6 to rotate the sill beam is improved. Furthermore, by using the magnetic attraction of the electromagnet 193 to the iron block 195, the two connecting ropes 21 are pulled and held on both sides of the passive rotating plate 13, preventing the three-axis clamping rotating device 6 and the sill beam from swaying after rotation. This allows for quick positioning of the rotated sill beam, thereby improving the visual inspection efficiency of each surface of the sill beam. At the same time, it effectively reduces the load on the servo motor and extends the service life of the servo motor.
