Description

Technical Field

[0001] The utility model relates to the technical field of laser scanners, and in particular to an auxiliary scanning device based on a laser scanner. Background Art

[0002] Laser 3D scanners use the collected data to perform 3D reconstruction calculations to create digital models of actual objects in the virtual world. These models have a wide range of uses, including industrial design, defect detection, reverse engineering, robot guidance, topographic measurement, medical information, bioinformatics, criminal identification, digital cultural relics collection, film production, game creation materials, etc. The production of 3D scanners does not rely on a single technology. Various reconstruction technologies have their advantages and disadvantages, and the cost and selling price also vary. There is no universal reconstruction technology. Instruments and methods are often limited by the surface characteristics of objects. For example, optical technology is not easy to handle shiny (high albedo), mirrored or translucent surfaces, and laser technology is not suitable for fragile or easily deteriorating surfaces.

[0003] The patent specification with announcement number CN214426654U discloses a three-dimensional laser scanner fixing mechanism, including a base plate, a support plate and a scanner fixedly installed on the top of the support plate, side plates are fixedly installed on both sides of the top of the base plate, threaded rods are fixedly connected to the middle parts of the two side plates, two sleeves are threadedly connected to the two threaded rods, and slide interfaces are rotatably provided on the outer surfaces of the two sleeves surrounding the sleeves, and two connecting rods for being hinged to the corresponding slide interfaces are hingedly provided on both sides of the bottom of the support plate.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for adjustment to different heights and rotation angles during use. In actual applications, when it is necessary to scan objects at different heights and multiple angles, the fixed structure is not convenient for adjustment. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model proposes an auxiliary scanning device based on a laser scanner, which solves the problem that the traditional laser scanner supporting equipment established in the related technology generally adopts a fixed structure or a manually adjustable structure. When scanning objects of different heights or requiring multi-angle scanning, the fixed structure leads to limitations on the scanned objects and is very inconvenient during manual adjustment.

[0006] The technical solution of the utility model is as follows:

[0007] An auxiliary scanning device based on a laser scanner comprises a device body, wherein a cylinder is fixedly connected inside the device body, a piston rod is slidably connected inside the cylinder, one end of the piston rod is fixedly connected to a sliding rod, the outside of the piston rod is connected to a gear 1 through a bearing, two round rods are fixedly connected to the top of the device body, a rotating groove is provided at the bottom of the gear 1, the round rod is in contact with the rotating groove, a connecting rod is connected to the top of the sliding rod through a bearing, a rotating rod 1 is fixedly connected to the top of the gear 1, a first sliding rod is slidably connected inside the rotating rod 1, the top of the gear 1 is also fixedly connected to a rotating rod 2, a second sliding rod is slidably connected inside the rotating rod 2, the top of the second sliding rod is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to the laser scanner body.

[0008] Preferably, the rotating rod 1 and the rotating rod 2 are symmetrically distributed, and the piston rod is slidably connected to the device body.

[0009] Preferably, the piston rod extends to an outer side of gear one, and the sliding rod is connected to gear one via a bearing.

[0010] Preferably, one end of the first sliding rod is fixedly connected to the bottom of the connecting plate, and one end of the connecting rod is fixedly connected to the bottom of the connecting plate.

[0011] Preferably, a servo motor is provided inside the device body, and a support plate is fixedly connected to the bottom of the servo motor.

[0014] Preferably, the output shaft extends to the top position of the equipment body, and the output shaft is connected to the equipment body via a bearing.

[0015] The working principle and beneficial effects of the utility model are:

[0016] In the utility model, the movement of the connecting plate will drive the first slide bar and the second slide bar to move respectively, and the movement of the connecting plate will also drive the laser scanner body to move. When the laser scanner body moves to the same horizontal plane as the scanned object, the staff can stop operating the cylinder and then perform laser scanning. The above device can facilitate the staff to scan objects of different heights without manually adjusting the equipment, thereby improving the scanning efficiency and solving the problem that the traditional laser scanner support equipment generally adopts a fixed structure or a manually adjusted structure, and when scanning objects of different heights or multi-angle scanning is required, due to the fixed structure, it will lead to limitations on the scanned object and very inconvenient manual adjustment.

[0017] In the utility model, the first slide bar and the second slide bar rotate simultaneously, which in turn drives the connecting plate to rotate, and the connecting plate rotates simultaneously, which drives the laser scanner body to rotate. At this time, the staff can control the rotation angle of the laser scanner body by operating the servo motor, so as to achieve a comprehensive scanning of the scanned objects at multiple angles. The above device can facilitate the staff to scan the scanned objects at different angles or even multiple angles without manually rotating the equipment, thereby improving the scanning efficiency and solving the problem that the traditional laser scanner support equipment generally adopts a fixed structure or a manually adjustable structure. When scanning objects at different heights or scanning at multiple angles, due to the fixed structure, it will lead to limitations on the scanned objects and very inconvenience in manual adjustment.

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0026] like Figure 1~Figure 3 As shown, this embodiment proposes an auxiliary scanning device based on a laser scanner, including a device body 1, a cylinder 2 is fixedly connected inside the device body 1, a piston rod 3 is slidably connected inside the cylinder 2, a sliding rod 5 is fixedly connected to one end of the piston rod 3, a gear 4 is connected to the outside of the piston rod 3 through a bearing, two round rods are fixedly connected to the top of the device body 1, a rotating groove is opened at the bottom of the gear 4, the round rods and the rotating groove are in contact, a connecting rod 6 is connected to the top of the sliding rod 5 through a bearing, a rotating rod 7 is fixedly connected to the top of the gear 4, a first sliding rod 8 is slidably connected to the rotating rod 7, a rotating rod 2 9 is also fixedly connected to the top of the gear 4, a second sliding rod 10 is slidably connected to the rotating rod 2 9, a connecting plate 11 is fixedly connected to the top of the second sliding rod 10, and a laser scanner body 12 is fixedly connected to the top of the connecting plate 11.

[0027] In this embodiment, the rotating rod 1 7 and the rotating rod 2 9 are symmetrically distributed, and the piston rod 3 is slidably connected to the device body 1, so that the cylinder 2 can drive the piston rod 3 to slide up and down.

[0028] In this embodiment, the piston rod 3 extends to the outer side of the gear 1 4 , and the sliding rod 5 is connected to the gear 1 4 via a bearing, which can facilitate the movement of the piston rod 3 and drive the sliding rod 5 to move at the same time.

[0029] In this embodiment, one end of the first sliding rod 8 is fixedly connected to the bottom of the connecting plate 11, and one end of the connecting rod 6 is fixedly connected to the bottom of the connecting plate 11, which can facilitate the movement of the connecting rod 6 and drive the connecting plate 11 to move at the same time.

[0030] When in use, the staff first installs and fixes the laser scanner body 12 on the connecting plate 11, and then uses the calibration bubble to adjust to ensure that the instrument is level, and then starts scanning. When laser scanning is required for scanning objects at different heights, the staff can start the cylinder 2 to drive the piston rod 3 inside it to move. When the piston rod 3 moves, it will drive the sliding rod 5 to move. When the sliding rod 5 moves, it will drive the connecting rod 6 to move. When the connecting rod 6 moves, it will drive the connecting plate 11 to move. The movement of the connecting plate 11 will respectively drive the first sliding rod 8 and the second sliding rod 10 to move. When the connecting plate 11 moves, it will also drive the laser scanner body 12 to move. When the laser scanner body 12 moves to the same level as the scanned object, the staff can stop operating the cylinder 2 and then perform laser scanning. The above device allows the staff to scan scanning objects at different heights without manually adjusting the equipment, thereby improving the scanning efficiency. Example 2

[0031] like Figure 4~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a servo motor 13 is provided inside the device body 1, and a support plate 14 is fixedly connected to the bottom of the servo motor 13 to facilitate the support of the servo motor 13.

[0032] In this embodiment, the support plate 14 is fixedly connected to a side wall of the inner cavity of the device body 1 , and the output shaft 15 is rotatably connected inside the servo motor 13 , so that the output shaft 15 can be driven to rotate by controlling the servo motor 13 .

[0033] In this embodiment, one end of the output shaft 15 is fixedly connected to a gear 2 16 , and the gear 2 16 is meshed with the gear 1 4 , so that the gear 2 16 can rotate and drive the gear 1 4 to rotate at the same time.

[0034] In this embodiment, the output shaft 15 extends to the top position of the device body 1 , and the output shaft 15 is connected to the device body 1 via a bearing, so that the servo motor 13 can drive the gear 2 16 to rotate via the output shaft 15 .

[0035] When it is necessary to perform multi-angle scanning on the scanned object, the staff first energizes and connects the servo motor 13. After the servo motor 13 is energized, the output shaft 15 inside it will start to rotate. When the output shaft 15 rotates, it will drive the gear 2 16 to rotate. When the gear 2 16 rotates, it will drive the gear 1 4 to rotate. When the gear 1 4 rotates, it will respectively drive the rotating rod 1 7 and the rotating rod 2 9 to rotate. When the rotating rod 1 7 and the rotating rod 2 9 rotate, they will respectively drive the first slide bar 8 and the second slide bar 10 to rotate. When the first slide bar 8 and the second slide bar 10 rotate, they will drive the connecting plate 11 to rotate. When the connecting plate 11 rotates, it will drive the laser scanner body 12 to rotate. At this time, the staff can control the rotation angle of the laser scanner body 12 by operating the servo motor 13, so as to achieve comprehensive scanning of the scanned objects at multiple angles. The above device can facilitate the staff to scan the scanning objects at different angles or even multiple angles without manually rotating the equipment, thereby improving the scanning efficiency.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
