Description

Technical Field

[0001] The utility model relates to the technical field of industrial TOF cameras, in particular to an industrial TOF camera with high freedom for accurate information acquisition. Background Technique

[0002] TFO (Through-Focus-Optics) cameras are a type of camera widely used in the industrial field. Industrial TOF cameras can measure the placed objects to obtain high-precision and clear images of the required objects. At the same time, they can capture information at different levels of the object, so as to achieve depth perception, providing high-precision, fast and reliable image acquisition and analysis capabilities to ensure efficient production and product quality. However, for the existing sampling devices of industrial TOF cameras, when in use, the objects need to be placed under the TOF camera. And since the camera is fixedly installed, it is very labor-consuming and troublesome to pick up and place heavy objects, which will lead to a decrease in the acquisition efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide an industrial TOF camera with high freedom for accurate information acquisition, so as to solve the problem that it is very troublesome to pick up heavy objects mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an industrial TOF camera with high freedom for accurate information acquisition, including a bottom plate. The outer surface of the bottom plate is fixedly installed with a slide rail, and both ends of the slide rail are fixedly installed with limit fixing blocks, and the limit fixing blocks are threadedly connected with the slide rail. The outer surfaces on both sides of the bottom plate are fixedly installed with columns, and a cross-moving rod is slidably installed on the outer surface of the columns. The middle outer surface of the cross-moving rod is fixedly installed with a bidirectional motor, and the output end of the bidirectional motor penetrates the outer surface of the cross-moving rod. A sliding mechanism is arranged on the outer surface of the bottom plate, and the feeding can be made more convenient through the sliding mechanism.

[0005] Preferably, the sliding mechanism includes: an electric sliding plate, which is slidably installed on the outer surface of the slide rail, and the slide rail is snap-connected with the electric sliding plate. A rotating flat plate motor is fixedly installed on the outer surface of the electric sliding plate, and a load platform is fixedly installed on the outer surface of the rotating flat plate motor, and the load platform is rotatably connected with the electric sliding plate. A strip-shaped groove is arranged on the outer surface of the load platform.

[0006] By adopting the above technical solution, the load platform can be moved out from under the sampling camera through the electric sliding plate, so that the lifting device and the forklift can lift and place heavy objects without touching the sampling camera. At the same time, through the strip-shaped groove on the outer surface of the load platform, the placed objects can find the correct position on the load platform and will not deviate too much from the sampling camera, resulting in image acquisition deviation.

[0007] Preferably, a rotation engagement mechanism is provided between the upright column and the crosswise moving rod, enabling the crosswise moving rod to move up and down smoothly through the rotation engagement mechanism.

[0008] Adopting the above technical solution, it is possible to conveniently adjust the position and height of the crosswise moving rod, enabling the height of the sampling camera to be adjusted, so that when measuring items of different heights and sizes, the height can be changed to make the collected information more accurate.

[0009] Preferably, the rotation engagement mechanism includes: a worm gear and rack. The worm gear and rack is fixedly installed on the side surface of one end of the upright column, and the upright column is engaged with the crosswise moving rod. A first gear is rotatably installed inside the crosswise moving rod, and the first gear is fixedly installed on the outer surface of the output end of the bidirectional motor. A worm is rotatably installed inside the crosswise moving rod, and a second gear is fixedly installed on the outer surface of one end of the worm, and the second gear is engaged with the first gear. The worm is engaged with the worm gear and rack.

[0010] Adopting the above technical solution, through the synchronous rotation of the bidirectional motor, the heights on both sides of the crosswise moving rod can be kept consistent during movement. At the same time, due to the self-locking property of the worm and the worm gear and rack, the crosswise moving rod can maintain its height without moving or falling by itself.

[0011] Preferably, a rotation mechanism is provided on the outer surface of one end of the crosswise moving rod, enabling the object placed on the load platform to be imaged from different directions through the rotation mechanism.

[0012] Adopting the above technical solution, it is possible to change the direction of the image collected by the sampling camera and collect the data of the items placed above the load platform in all directions.

[0013] Preferably, the rotation mechanism includes: a rotating block rod. The rotating block rod is rotatably installed on the outer surface of one end of the crosswise moving rod close to the bidirectional motor. The axis of the rotating block rod is connected to the servo motor, and an electric rotating mounting frame is rotatably installed on the outer surface of the rotating block rod, and a sampling camera is fixedly installed inside the electric rotating mounting frame. The sampling camera and the electric rotating mounting frame are fixedly connected by screws.

[0014] Adopting the above technical solution, the rotation of the rotating block rod will drive the sampling camera to rotate together, and the data of the item will be collected by the downward movement of the crosswise moving rod. At the same time, the imaging direction of the sampling camera can be twisted by the rotation of the electric rotating mounting frame, and in cooperation with the movement of the electric sliding plate, the back of the item can be collected.

[0015] Preferably, heat sinks are provided on the outer surface of the sampling camera, and the camera of the sampling camera faces the direction of the load platform.

[0016] With the above technical solution, by setting the heat sink on the outer surface of the sampling camera, the heat dissipation rate of the sampling camera is enhanced, enabling the sampling camera to operate stably during sampling.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This industrial TOF camera with high-degree-of-freedom and precise information acquisition:

[0018] 1. When loading materials, it is necessary to first move the electric sliding plate so that the electric sliding plate moves out from under the crosswise rod along the direction of the slide rail. Subsequently, the item for which information needs to be acquired can be hoisted above the loading platform. At the same time, the position for placing the item is confirmed through the strip-shaped grooves on the outer surface of the loading platform, ensuring that the item on the loading platform does not deviate too much, which may lead to a decrease in acquisition accuracy, thus facilitating the hoisting and placement of heavier items for measurement.

[0019] 2. As the two-way motor rotates, it drives the first gears on both sides to rotate together, and also drives the second gears meshing with the first gears to rotate. Through the rotation of the second gears, the worm rotates, causing the worm to rotate and move up and down through the rack and pinion, enabling the two sides of the crosswise rod to rise and fall simultaneously without tilting, improving the accuracy when acquiring data. At the same time, due to the self-locking property of the worm and the rack and pinion, the crosswise rod will not fall automatically.

[0020] 3. By controlling the up and down movement of the crosswise rod to adapt to the acquisition of information for items of different heights and sizes, after acquiring the data on the top, the acquisition data direction of the sampling camera can be changed by rotating the rotating block rod. In cooperation with the movement of the electric sliding plate, the data on the side surface of the item can be acquired, and the orientation of the loading platform can be changed by rotating the flat plate motor, enabling the acquisition of data on both sides of the item.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , the present utility model provides a technical solution: an industrial TOF camera for highly accurate information acquisition with high degrees of freedom, including a bottom plate 1, a slide rail 2 is fixedly installed on the outer surface of the bottom plate 1, and limit fixing blocks 3 are fixedly installed at both ends of the slide rail 2, and the limit fixing blocks 3 are threadedly connected to the slide rail 2. Columns 4 are fixedly installed on the outer surfaces of both sides of the bottom plate 1, and a transverse moving rod 5 is slidably installed on the outer surface of the column 4. A bidirectional motor 10 is fixedly installed on the middle outer surface of the transverse moving rod 5, and the output end of the bidirectional motor 10 penetrates the outer surface of the transverse moving rod 5. A sliding mechanism is provided on the outer surface of the bottom plate 1, which makes the feeding more convenient through the sliding mechanism.

[0030] The position of the column 4 is determined by the bottom plate 1. Through the limit fixing blocks 3 provided at both ends of the slide rail 2, the electric sliding plate 6 will not move beyond the limit and fall off the bottom plate 1 during movement.

[0031] The sliding mechanism includes: an electric sliding plate 6, the electric sliding plate 6 is slidably installed on the outer surface of the slide rail 2, and the slide rail 2 is snap-connected to the electric sliding plate 6. A rotating flat plate motor 7 is fixedly installed on the outer surface of the electric sliding plate 6, and a loading platform 8 is fixedly installed on the outer surface of the rotating flat plate motor 7, and the loading platform 8 is rotatably connected to the electric sliding plate 6. A strip-shaped groove is provided on the outer surface of the loading platform 8.

[0032] When it is necessary to collect and measure heavier items, the load platform 8 can be first moved outwards by the electric sliding plate 6 so that the load platform 8 is moved out from below the sampling camera 16. Subsequently, the item can be lifted by a forklift or a crane and placed above the load platform 8. The strip-shaped grooves on the outer surface of the load platform 8 can provide a reference for the placed item, preventing the item from being placed too much off-center, facilitating the placement of the heavier item on the outer surface of the load platform 8. Then, the electric sliding plate 6 can be started to transport the item below the sampling camera 16 for information collection, facilitating loading and unloading.

[0033] A rotation engagement mechanism is provided between the vertical column 4 and the transverse movement rod 5, enabling the transverse movement rod 5 to move up and down smoothly through the rotation engagement mechanism.

[0034] The rotation of the bidirectional motor 10 drives the first gears 11 on both sides to rotate, causing the second gears 12 engaged with the first gears 11 to rotate together. The rotation of the second gears 12 drives the worm 13 to rotate, causing the worm 13 to rotate and contact the worm gear rack 9, driving the transverse movement rod 5 to move up and down, maintaining the parallelism of both ends of the transverse movement rod 5, reducing information errors when the sampling camera 16 collects data, and improving the accuracy of the collected data.

[0035] The rotation engagement mechanism includes: a worm gear rack 9, which is fixedly installed on the side surface of one end of the vertical column 4, and the vertical column 4 is engaged with the transverse movement rod 5. A first gear 11 is rotatably installed inside the transverse movement rod 5, and the first gear 11 is fixedly installed on the outer surface of the output end of the bidirectional motor 10. A worm 13 is rotatably installed inside the transverse movement rod 5, and a second gear 12 is fixedly installed on the outer surface of one end of the worm 13, and the second gear 12 is engaged with the first gear 11, and the worm 13 is engaged with the worm gear rack 9.

[0036] Due to the self-locking property of the worm 13 and the worm gear rack 9, after the position of the transverse movement rod 5 on the vertical column 4 is adjusted, the transverse movement rod 5 will not automatically fall due to external reasons, maintaining the height of the transverse movement rod 5 on the vertical column 4 and reducing the deviation of the collected data caused by the movement of the transverse movement rod 5.

[0037] A rotation mechanism is provided on the outer surface of one end of the transverse movement rod 5, enabling the object placed on the load platform 8 to be imaged from different directions.

[0038] After collecting the data above the item, the rotation of the rotating block rod 14 can drive the sampling camera 16 to rotate, changing the orientation of the camera of the sampling camera 16, and adjusting the height of the transverse movement rod 5 to facilitate the collection of data on the side surface of the item.

[0039] The rotating mechanism includes: a rotating block rod 14, which is rotatably installed on the outer surface of one end of the cross-moving rod 5 close to the bidirectional motor 10. The axis of the rotating block rod 14 is connected to the servo motor, and an electric rotating mounting bracket 15 is rotatably installed on the outer surface of the rotating block rod 14. And a sampling camera 16 is fixedly installed inside the electric rotating mounting bracket 15, and the sampling camera 16 is fixedly connected to the electric rotating mounting bracket 15 by screws.

[0040] Through the strip-shaped groove on the outer surface of the loading platform 8, the article can be kept at the center of the loading platform 8, so that the rotating flat plate motor 7 will not generate offset during use. At the same time, the rotating flat plate motor 7 can change the orientation of the article, and at the same time, in cooperation with the rotation of the electric rotating mounting bracket 15, the orientation of the sampling camera 16 is changed to collect the data of the article in all directions.

[0041] A heat sink is arranged on the outer surface of the sampling camera 16, and the camera of the sampling camera 16 faces the direction of the loading platform 8.

[0042] Through the connection mode of the electric rotating mounting bracket 15 and the sampling camera 16, the sampling camera 16 can be conveniently replaced. At the same time, the heat dissipation of the sampling camera 16 can be improved through the heat sink on the outer surface of the sampling camera 16, so that the sampling camera 16 can operate stably.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
