Description

Technical Field

[0001] This utility model relates to the field of cameras, and more particularly to a multi-functional camera. Background Technology

[0002] With the development of arc welding robots, welding automation is increasingly reliant on machine vision. Currently, commonly used vision types include wired laser vision sensors, 3D cameras, and molten pool cameras.

[0003] However, these sensors and cameras have relatively limited functions, and each sensor or camera can only solve a certain type of problem. To meet complex application requirements, they often need to be used in combination, which increases the cost of use and the complexity of the system.

[0004] Therefore, the vision sensors and cameras used in the welding robots mentioned above have relatively simple functions. To meet complex application requirements, they often need to be used in combination, which increases the cost and system complexity. A multi-functional camera can be designed to solve the above problems. Utility Model Content

[0005] To overcome the problem that the vision sensors and cameras used in welding robots have relatively simple functions, they often need to be used in combination to meet complex application requirements, which increases the cost and system complexity.

[0006] The technical solution of this utility model is as follows: a multi-functional camera, including an inner shell and an outer shell disposed on the outside of the inner shell, and also including a camera assembly disposed on the inner shell and a supplementary lighting assembly disposed on the outer shell; the camera assembly includes a laser emitter, a supplementary lighting board, a diffuser, an image recognition sensor, and an optical lens; the supplementary lighting assembly includes a fixing block, a first rotating block, a first bevel gear, a second rotating block, a second bevel gear, a reflector, a third bevel gear, a transmission shaft, and a second motor.

[0007] Preferably, when using the weld seam tracking function, the laser emitter is turned on and the supplementary light panel is turned off. The laser line projected by the laser emitter shines on the surface of the object being measured after passing through the circular hole between the supplementary light panel and the diffuser cloth. The reflected light is then reflected by the optical lens to the image recognition sensor, allowing the image recognition sensor to obtain the three-dimensional information of the object. When using the molten pool camera function, the supplementary light panel is turned on and the laser emitter is turned off. The light emitted by the supplementary light panel shines on the weld pool in a more uniform and softer manner after passing through the diffuser cloth. The reflected light is reflected by the optical lens to the image recognition sensor, thus allowing the molten pool information to be seen. During this process, the second motor can rotate the first rotating block through the drive shaft, the third bevel gear, and the first bevel gear. The first rotating block then rotates the second rotating block through the second bevel gear, thereby simultaneously unfolding the four reflectors. The light emitted by the supplementary light panel will reflect in all directions after illuminating the weldment, and the reflectors will re-emit some of the reflected light back to the weld pool to improve the illumination brightness and improve the image quality.

[0008] Preferably, a laser emitter is installed inside the inner shell, a fill light plate is installed at the front end of the laser emitter, a diffuser is installed at the front end of the fill light plate, and a round hole is opened in the middle of both the fill light plate and the diffuser.

[0009] Preferably, an image recognition sensor is installed on one side of the laser emitter, and an optical lens is installed at the front end of the image recognition sensor. The extension surfaces of the laser emitter, the image recognition sensor, and the optical lens intersect in a straight line.

[0010] Preferably, three fixed sleeves are installed at the lower end of the inner shell, and two slide rods are fixedly connected to the lower end of the inner side of the outer shell. A lead screw that is rotatably connected to the outer shell is provided between the two slide rods. The slide rods are slidably connected to the fixed sleeves, and the lead screw is clearance-fitted to the fixed sleeves. The rear end of the lead screw is connected to a first motor through a coupling.

[0011] Preferably, two fixing blocks are fixed to each of the four corners of the front end of the outer shell, and a first rotating block that is rotatably connected to the fixing blocks is provided at the upper and lower ends of the outer shell. A first bevel gear is fixed to the center of each first rotating block, and a second rotating block that is rotatably connected to the fixing blocks is provided on both sides of the outer shell.

[0012] Preferably, a second bevel gear is fixedly connected to both sides of the first rotating block and the upper and lower ends of the second rotating block, and two adjacent second bevel gears mesh with each other. A reflector is fixedly connected to the front end of both the first rotating block and the second rotating block.

[0013] Preferably, the rear end of the first bevel gear at the upper end is meshed with a third bevel gear, the rear end of the third bevel gear is fixedly connected to a drive shaft, and the drive shaft is rotatably connected to the housing. The rear end of the drive shaft is connected to a second motor through a coupling.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a camera component and a supplementary lighting component, two functions, weld seam tracking and molten pool monitoring, can be achieved within a single camera. The weld seam tracking function can be used to detect the weld seam and plan the welding trajectory before welding, and the molten pool can be monitored during the welding process to observe the welding quality. One camera achieves two functions, reducing system complexity and saving costs. In addition, it also makes the supplementary lighting more uniform and softer while improving the brightness of the supplementary lighting. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment: a multi-functional camera, including an inner shell 1 and an outer shell 4 disposed outside the inner shell 1, and also including an imaging component disposed on the inner shell 1 and a supplementary lighting component disposed on the outer shell 4; the imaging component includes a laser emitter 201, a supplementary lighting plate 202, a diffuser 203, an image recognition sensor 204, and an optical lens 205; the supplementary lighting component includes a fixing block 801, a first rotating block 802, a first bevel gear 803, a second rotating block 804, a second bevel gear 805, a reflector 806, a third bevel gear 807, a transmission shaft 808, and a second motor 809; three fixing sleeves 3 are installed at the lower end of the inner shell 1; two sliding rods 5 are fixedly connected to the lower end of the inner side of the outer shell 4; a lead screw 6 is disposed between the two sliding rods 5 and rotatably connected to the outer shell 4; the sliding rods 5 are slidably connected to the fixing sleeves 3; the lead screw 6 is clearance-fitted to the fixing sleeves 3; and the rear end of the lead screw 6 is connected to the first motor 7 through a coupling.

[0025] Please see Figures 2-6 In this embodiment, a laser emitter 201 is installed inside the inner shell 1. A fill light plate 202 is installed at the front end of the laser emitter 201, and a diffuser cloth 203 is installed at the front end of the fill light plate 202. Both the fill light plate 202 and the diffuser cloth 203 have circular holes in their middles. An image recognition sensor 204 is installed on one side of the laser emitter 201, and an optical lens 205 is installed at the front end of the image recognition sensor 204. The positional relationship between the laser emitter 201, the image recognition sensor 204, and the optical lens 205 follows Scherrer's Law, meaning that the extended surfaces of the three intersect on a straight line. Two fixing blocks 801 are fixedly attached to each of the four corners of the front end of the outer shell 4. The upper and lower ends of the outer shell 4 are provided with joints that rotate with the fixing blocks 801. The first rotating block 802 is dynamically connected, and a first bevel gear 803 is fixedly connected to the center of the first rotating block 802. The outer shell 4 is provided with a second rotating block 804 on both sides, which is rotatably connected to the fixed block 801. A second bevel gear 805 is fixedly connected to both sides of the first rotating block 802 and the upper and lower ends of the second rotating block 804, and two adjacent second bevel gears 805 mesh. A reflector 806 is fixedly connected to the front end of the first rotating block 802 and the second rotating block 804. A third bevel gear 807 meshes with the rear end of the upper first bevel gear 803. A drive shaft 808 is fixedly connected to the rear end of the third bevel gear 807, and the drive shaft 808 is rotatably connected to the outer shell 4. The rear end of the drive shaft 808 is connected to a second motor 809 through a coupling.

[0026] When in use, firstly, when using the weld seam tracking function, turn on the laser emitter 201 and turn off the fill light plate 202. The laser line projected by the laser emitter 201 shines on the surface of the object being measured after passing through the circular hole between the fill light plate 202 and the soft light cloth 203. The reflected light is then reflected by the optical lens 205 to the image recognition sensor 204 so that the image recognition sensor 204 can obtain the three-dimensional information of the object.

[0027] When using the molten pool camera function, turn on the fill light panel 202 and turn off the laser emitter 201. The light emitted by the fill light panel 202 shines on the welding molten pool in a more uniform and softer manner after passing through the diffuser 203. The reflected light is reflected by the optical lens 205 to the image recognition sensor 204, and then the molten pool information can be seen.

[0028] During this process, the second motor 809 can rotate the first rotating block 802 through the transmission shaft 808, the third bevel gear 807 and the first bevel gear 803. The first rotating block 802 then rotates the second rotating block 804 through the second bevel gear 805, so that the four reflectors 806 can be deployed simultaneously. The light emitted by the supplementary light plate 202 will be reflected in all directions after it shines on the weldment. The reflectors 806 will re-emit some of the light reflected in all directions back to the weld pool to improve the lighting brightness and improve the image quality.

[0029] Through the above steps, by setting up the camera component and the supplementary lighting component, two functions, weld seam tracking and molten pool monitoring, can be achieved within a single camera. The weld seam tracking function can be used to detect the weld seam and plan the welding trajectory before welding, and the molten pool can be monitored during the welding process to observe the welding quality. One camera achieves two functions, reducing system complexity and saving costs. In addition, it also makes the supplementary lighting more uniform and softer while improving the brightness of the supplementary lighting.
