Abstract
Description
Technical Field
[0001] This invention relates to the technical field of wheel welding, and specifically to an intelligent tracking device for wheel weld seams. Background Technology
[0002] During the production and processing of steel wheels, the wheel hub and spokes need to be welded. Different vehicle models use different wheel shapes, and the number and shape of the spokes vary for different wheel shapes. Furthermore, the wheel hubs also differ, therefore the welding positions of the spokes and the hub also vary. Current welding methods primarily rely on software systems to control the position of the welding torch on a robotic arm. After welding, the weld needs to be inspected to determine if there are any instabilities or deviations. Current inspection methods mainly involve flaw detectors and visual inspection of the weld. However, due to the obstruction of the spokes, blind spots exist, causing workers to frequently overlook parts during weld inspection, resulting in some defective products entering the market.
[0003] Therefore, this invention proposes an intelligent tracking device for wheel welds to address the shortcomings of existing technologies. Summary of the Invention
[0004] In order to solve the problem of blind spots in the field of vision when observing the appearance of wheel welds by the human eye, as mentioned in the background art above.
[0005] This invention provides the following technical solution:
[0006] A smart tracking device for wheel weld seams, including
[0007] Positioning station;
[0008] The robotic arm is located on the ground to one side of the positioning platform;
[0009] The first mounting plate is located at the end of the robotic arm;
[0010] The welding torch and the first CCD camera are respectively mounted on the first mounting plate;
[0011] A rotating sleeve is rotatably mounted on a positioning platform, and the outer circumferential wall of the rotating sleeve has a positioning step for a positioning hub.
[0012] The second mounting plate is set on the positioning platform and located inside the rotating sleeve;
[0013] The guide tube is U-shaped and movably mounted on the second mounting plate. A U-shaped limiting opening is provided along the side wall of the guide tube.
[0014] A movable plate, which can be movably set on the positioning platform;
[0015] The third mounting plate is mounted on the movable plate;
[0016] The connecting column is movably mounted on the third mounting plate;
[0017] Several movable columns are arranged in a straight line and distributed along the central axis of the connecting column. The opposite faces of two adjacent movable columns are connected by springs, and one end of the movable column is connected to the connecting column by a spring.
[0018] Several insert plates are respectively set on the same side of several movable columns;
[0019] The second CCD camera is mounted on a plate on the movable column at the other end.
[0020] The connecting column drives the moving column to enter one end of the guide tube in sequence, and the insert plate enters the limiting port. The spring bends when two adjacent connecting columns rotate relative to each other, so that the second CCD camera can move along the guide tube to capture the blind zone weld.
[0021] Preferably, the movable column has a cable routing hole that passes through the movable column, and connector tubes are respectively provided at both ends of the cable routing hole. The connector tubes on two adjacent movable columns are connected and communicated through a flexible hose. The flexible hose is located inside the spring. The movable column corresponding to the connecting column has a through hole that communicates with the cable routing hole.
[0022] Preferably, the third mounting base has a third cylinder, the output end of which is fixedly connected to the connecting column.
[0023] Preferably, the positioning platform is provided with a ball screw module and a guide rod, the guide rod slides through the moving plate, and the ball nut on the ball screw module passes through the moving plate and is fixedly connected to the moving plate.
[0024] Preferably, a second cylinder is provided on the second mounting plate, and a base is provided on the output end of the second cylinder, with the guide tube fixedly connected to the base.
[0025] Preferably, the outer circumferential wall of the rotating sleeve is provided with a plurality of positioning plates arranged in a circular pattern, and a first cylinder is provided on the positioning plate, and a pressure column is provided at the output end of the first cylinder.
[0026] Preferably, a toothed ring is fixedly sleeved on the outer circumferential wall of the rotating sleeve, a servo motor is fixedly connected to the positioning platform, and a gear that meshes with the toothed ring is fixedly connected to the output end of the servo motor.
[0027] Compared with existing technologies, it has the following advantages:
[0028] This application uses a base to move a guide tube, allowing the U-shaped opening of the guide tube to fit over the blind spot of the spoke. Then, a connecting column sequentially sends a moving column into the guide tube, and the insert plate enters the limiting port. When two adjacent moving columns rotate relative to each other, the spring deforms, enabling the second CCD camera on the insert plate to move along the guide tube. This allows the second CCD camera to capture images of the weld seam, enabling weld seam path tracking before welding and imaging of the weld seam after welding, avoiding blind spots in human observation. Simultaneously, the second CCD camera can capture images of the intersection of the spokes and the hub before welding, verifying the welding path of the welding torch.
[0029] This application uses a first cylinder to drive the pressure column to move, so that the pressure column can press the wheel hub tightly onto the rotating sleeve, thereby increasing stability.
[0030] This application uses a first CCD camera to capture the relative position of the spokes and the hub, and uses the rotation of the rotating sleeve to make the spokes face the center of the U-shaped opening of the guide tube. Attached Figure Description

Detailed Implementation
[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0043] As attached Figure 1-9 As shown:
[0044] This invention provides an intelligent tracking device for wheel weld seams, comprising a positioning platform 10; a robotic arm 20 located on the ground to one side of the positioning platform 10; a first mounting plate 22 disposed at the end of the robotic arm 20; a welding torch 21 and a first CCD camera 23 respectively disposed on the first mounting plate 22; a rotating sleeve 30 rotatably disposed on the positioning platform 10, the outer circumferential wall of the rotating sleeve 30 having a positioning step 31 for positioning the wheel hub; the lower end of the rotating sleeve 30 is rotatably connected to the positioning platform 10 via a bearing; a second mounting plate 54 disposed on the positioning platform 10 and located inside the rotating sleeve 30; a U-shaped guide tube 50 movably disposed on the second mounting plate 54, the side wall of the guide tube 50 having a U-shaped limiting opening 51 along the guide tube 50; and a movable plate 60 movably disposed on the positioning platform 10. The third mounting plate 72 is mounted on the movable plate 60; the connecting column 70 is movably mounted on the third mounting plate 72; a plurality of movable columns 80 are arranged in a straight line and distributed along the central axis of the connecting column 70, and the opposite faces of two adjacent movable columns 80 are connected by springs 81, and one end of the movable column 80 is connected to the connecting column 70 by springs 81; a plurality of insert plates 82 are respectively mounted on the same side of the plurality of movable columns 80; the second CCD camera 90 is mounted on the insert plate 82 on the other end of the movable column 80; wherein, the connecting column 70 drives the movable columns 80 to enter one end of the guide tube 50 in sequence, and the insert plate 82 enters the limiting port 51, and the spring 81 bends when two adjacent connecting columns 70 rotate relative to each other, so that the second CCD camera 90 can move along the guide tube 50 to capture the blind zone weld.
[0045] Please see Figure 4 , 5 6. The movable column 80 has a cable routing hole 94 that passes through it. Connector tubes 92 are respectively provided at both ends of the cable routing hole 94. The connector tubes 92 on two adjacent movable columns 80 are connected and linked by a flexible hose 93 located inside the spring 81. The movable column 80 corresponding to the connecting column 70 has a through hole 91 that communicates with the cable routing hole 94. To facilitate cable routing, the data cable of the second CCD camera 90 can be first passed through the cable routing hole 94, then through the connector tube 92, the flexible hose 93, and the cable routing hole 94 in the adjacent movable column 80, and so on, finally exiting from the through hole 91. This allows the data cable of the second CCD camera 90 to be hidden internally during cable routing, without affecting the operation of the equipment, and also increases the overall organization.
[0046] Please see Figure 1 , 2 3, 4, The third mounting plate 72 has a third cylinder 71, and the output end of the third cylinder 71 is fixedly connected to the connecting column 70. This application enables the third cylinder 71 to drive the connecting column 70 to move by installing the third cylinder 71 on the third mounting plate 72.
[0047] Please see Figure 1 , 2 3. A ball screw module 62 and a guide rod 63 are provided on the positioning platform 10. The guide rod 63 slides through the moving plate 60, and the ball nut on the ball screw module 62 passes through the moving plate 60 and is fixedly connected to the moving plate 60. The ball screw module 62 provided in this application can drive the moving plate 60 to move along the guide rod 63, so that the straight line where the several moving columns 80 are located is aligned with one end of the guide tube 50.
[0048] Please see Figure 1 , 2 3. A second cylinder 53 is provided on the second mounting plate 54, and a base 52 is provided on the output end of the second cylinder 53. The guide tube 50 is fixedly connected to the base 52. The second cylinder 53 in this application can drive the base 52 to move on the second mounting plate 54, so that the base 52 drives the guide tube 50 to move, so that the U-shaped sidewall of the guide tube 50 can be located at the weld.
[0049] Please see Figure 1 , 2 3. Several positioning plates 42 arranged in a ring are provided on the outer circumferential wall of the rotating sleeve 30. A first cylinder 41 is provided on the positioning plate 42, and a pressure column 40 is provided at the output end of the first cylinder 41. The first cylinder 41 in this application can drive the pressure column 40 to move so that the pressure column 40 can press the wheel hub 100 of the car onto the rotating sleeve 30.
[0050] Please see Figure 9 A toothed ring 32 is fixedly sleeved on the outer circumferential wall of the rotating sleeve 30. A servo motor 34 is fixedly connected to the positioning table 10. A gear 33 that meshes with the toothed ring 32 is fixedly connected to the output end of the servo motor 34.
[0051] When this application is used:
[0052] It should be noted that the two ends of the spring 81 in this application are fixedly connected to the moving column 80. The weight of the moving column 80 and the spring 81 is insufficient to deform the spring 81. Therefore, in its natural state, all the moving columns 80 are still arranged in a straight line.
[0053] First, the hub 100 is fitted onto the positioning step 31 of the rotating sleeve 30. Then, the first cylinder 41 drives the pressure column 40 to move, so that the pressure column 40 can apply pressure to the hub 100, pressing the hub 100 tightly onto the positioning step 31. Then, the robotic arm 20 moves the first mounting plate 22 above the hub 100, and the first CCD camera 90 captures the position of the spokes 101 on the hub 100. Then, the servo motor 34 starts, causing the gear 33 to drive the gear ring 32 to rotate, and the gear ring 32 drives the rotating sleeve 30 to rotate until one of the spokes 101 rotates to the position of the U-shaped opening of the guide tube 50. Then, the servo motor 34 stops, and the first CCD camera 23 also stops capturing images. Then, the second cylinder 53 drives the base 52 to move, and the base 52 drives the guide tube 50 to move, so that the U-shaped opening of the guide tube 50 can fit onto one of the spokes. The outer perimeter of spoke 101 is then moved by the third cylinder 53, which in turn moves the connecting column 70, causing the connecting column 70 to move the moving column 80. The moving column 80 corresponding to the second CCD camera 90 will first enter the guide tube 50, while the insert plate 82 enters the limiting port 51. At this time, the second CCD camera 90 has started shooting and can capture the intersection of spoke 101 and hub 100. When the moving column 80 encounters the bending position of the guide tube 50, the spring 81 will gradually bend and deform to adapt to the change in the relative position of the two adjacent moving columns 80. Since the guide tube 50 surrounds the blind area of spoke 101 and hub 100, the second CCD camera 90 can capture the complete intersection of hub 100 and spoke 101 to verify whether the welding path in the system is the same as the actual welding path. If the deviation exceeds the error value, an alarm will be issued to remind the worker.
[0054] After the second CCD camera 90 finishes shooting, the third cylinder 71 drives the connecting column 70 back to its original position. Under the reset force of the spring 81, all the moving columns 80 remain in a straight line. Then the guide tube 50 also resets. Then the robotic arm 20 moves with the first mounting plate 22, so that the welding gun 21 on the first mounting plate 22 can weld the intersection of the car wheel hub 100 and the spokes 101. After welding, the guide tube 50 moves again to surround the weld blind area of the spokes 101. The second CCD camera 90 moves along the guide tube 50 again and shoots, thereby shooting the weld after welding. The first CCD camera 90 can also shoot the welding of the spokes 101 and the surface of the wheel hub 100.
[0055] The second CCD camera 90 of this application is capable of capturing the position of the weld before welding and capturing the condition of the weld after welding.
