Description

Technical Field

[0001] The present invention relates to the field of dot-drawing marking technology, and in particular to a long-distance dot-drawing marking device and method. Background Art

[0002] Currently, marking and indicating precise locations or drawing specific patterns on the surfaces of large equipment or structures is extremely difficult. Typically, this is done by photographing locations or creating renderings. However, this method is not physically marking the object, which can lead to errors and misunderstandings. Manually marking locations or drawing patterns using scaffolding or hanging baskets poses safety risks and is also inefficient and inaccurate.

[0003] For example, a prior art method and system for remote online tagging discloses a method that first establishes a communication relationship with a terminal MR device, obtains real-time video data captured by the MR device based on the communication relationship, and displays the video image. The real-time scene is then tagged and processed on the video image display interface to obtain tagged image information. Finally, the tagged image information is synchronized to the MR device via the communication relationship for display. Although this solution can improve the visual effect by displaying through the MR device compared to simply tagging the image, it is still not a physical tag and adds additional costs.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0031] Example 1:

[0032] This embodiment provides a long-distance dot-painting marking device that can accurately launch a projectile with a marking function to dot the pigment at the set position of the object to be marked; Figure 1 As shown, the long-distance dot marking device of this embodiment mainly includes a laser emitter 3 and a projectile launching device. The laser emitter 3 is installed on the upper side of the projectile launching device. The laser emitter 3 is used to locate the launching position of the projectile 5. The landing point of the projectile 5 launched by the projectile launching device is consistent with the laser marking point.

[0033] The projectile launcher is mounted on the upper side of the anti-shake gimbal 10. The anti-shake gimbal 10 includes a support platform and a gimbal bracket. The support platform and the gimbal bracket are connected by a rotating mechanism, which allows the projectile launcher to be adjusted in angle while providing stable support. The rotating mechanism can be implemented by means of a ball joint or other means, and the rotating mechanism has a locking mechanism that can lock the projectile launcher at a certain angle, facilitating a stable launch path for the projectile 5. The locking mechanism can be implemented by means of a locking pin or other structure.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, the projectile launching device includes a shell 1, on which a projectile magazine 4, a launching tube 2, a launching mechanism, and a battery pack 18 are installed. The shell 1 is installed on the upper side of the anti-shake gimbal 10, and the launching tube 2 is arranged in a horizontal state and extends a certain length from one end of the shell 1. A launching mechanism is arranged at the end of the launching tube 2; the projectile magazine 4 is arranged at the top of the shell 1 and is connected to the launching tube 2 through a pipe, so that the projectiles 5 can enter the launching tube 2, and the projectiles 5 are launched one by one under the driving action of the launching mechanism.

[0035] In this embodiment, a paint coating assembly is provided in the launch chamber. The paint coating assembly can coat the surface of the projectile 5 with a paint that performs a marking function, thereby providing ordinary projectiles 5 with a marking function, eliminating the need to manufacture special projectiles 5 and saving costs. Furthermore, the paint can be either powder or liquid to meet different marking requirements.

[0036] like Figure 3 As shown, the interior of the pellet chamber 4 is divided into a coating chamber 13 and a storage chamber 14 by a partition. The bottom of the storage chamber 14 is connected to the launch tube 2. The coating chamber 13 and the storage chamber 14 are connected at a certain height, and the height of the connecting port 17 between the two is higher than the coverage height of the pigment. A vibrating screen is provided in the coating chamber 13, and the vibrating screen is connected to a hoisting mechanism. The coating chamber 13 is also filled with pigment powder or pigment liquid. The pigment powder or pigment liquid exceeds a certain height of the vibrating screen, so that the pellets 5 can effectively contact the pigment after being added into the coating chamber 13 from the feed port 12. Through the vibration of the vibrating screen 15, the pellets 5 on it roll and fully contact the pigment, achieving the purpose of coating the pigment on the surface of the pellets 5.

[0037] After coating is completed, the vibrating screen is lifted upward by the hoisting mechanism to separate the pellets 5 from the pigment. Since the vibrating screen 15 is provided with mesh holes, the powdered pigment can leak out of the mesh holes, thereby separating the pigment powder from the pellets 5. For the pigment liquid, effective separation can also be achieved.

[0038] When the vibrating mesh 15 is raised to the connection port 17 between the corresponding coating chamber 13 and the storage chamber 14, a pushing mechanism is installed in the coating chamber 13 to allow the pellets 5 to smoothly enter the storage chamber 14. The pushing mechanism is located on the opposite side of the connection port 17 and is capable of pushing out the pigmented pellets 5. In this embodiment, the pushing mechanism includes an electric push rod and a push plate. The push plate is arranged in a vertical position, one side of which is connected to the electric push rod. In the initial state, the push plate is positioned near the side wall of the coating chamber 13. When the vibrating mesh rises to a height that allows it to separate from the pigment, the electric push rod is activated. The traction rope 16 of the hoisting mechanism in this embodiment is connected to the two side edges of the vibrating mesh 15, which can achieve stable lifting of the vibrating mesh 15.

[0039] It should be noted that the shape of the push plate is designed according to actual needs, and it is sufficient to ensure that the hanging of the traction rope 16 does not affect the normal movement of the push plate.

[0040] like Figure 1 As shown, the launching mechanism includes a launching drive module 6, an air pressure tank 8 and a pulse device 7. The air pressure tank 8 is connected to the launching drive module 6 through an air pipe. The pulse device 7 can be a control element such as a solenoid valve, which is installed on the air pipe between the air pressure tank 8 and the launching drive module 6. The pulse device 7 is used to control the high-pressure gas in the air pressure tank 8 to enter the launching chamber.

[0041] In order to further ensure the accuracy of the launch of the projectile 5, the long-distance dot marking device of this embodiment also includes a laser rangefinder. The laser rangefinder and the laser emitter 3 are both connected to the controller. The laser rangefinder is used to measure the target distance in real time. The controller can automatically adjust the angle of the laser emitter 3 according to the measurement results.

[0042] The laser rangefinder measures the target distance (the distance between the marker and the launch point) in real time and transmits the data to the controller. The controller analyzes the relationship between error and distance based on this data and combines it with a parabolic error model. It then uses a nonlinear fitting method to fit the error data and establish an error compensation model. The error compensation model calculates the adjustment values ​​and determines the parameters of the laser transmitter 3 that require adjustment.

[0043] The projectile launcher of this embodiment is equipped with an external interface 9, which can be connected to a terminal such as a computer or mobile phone, or wirelessly. The projectile launcher also includes an operation screen 11. A laser emitter 3 projects a marking point along a pre-set pattern, activating the launch drive module 6. The paint-coated projectile 5 is then launched through the launch tube 2, where it lands at the marking point.

[0044] Based on the launching principle, this embodiment launches the paint-coated projectile 5 to the target position at a long distance (5 to 50 meters), without the need for a special design of the projectile 5 structure, to achieve physical remote marking; and can automatically adjust the trajectory of the projectile 5 to ensure the launch accuracy.

[0045] Example 2:

[0046] This embodiment provides a remote point-drawing marking method, using the marking device described in Example 1, including:

[0047] Adjust the marking device's angle so that laser emitter 3 illuminates the desired dotted location along a preset trajectory. Activate the projectile launcher, and paint-coated projectiles 5 are ejected from launch tube 2, landing at the laser-marked point. Adjust the laser emitter's angle so that it illuminates the next dotted location, and the projectile launcher fires projectiles 5 along the preset trajectory.

[0048] During the marking process, the laser rangefinder measures the target distance in real time. Based on the laser ranging results and the parabolic error model, the error distance that needs to be adjusted is calculated and an error compensation model is established. The angle of the laser emitter 3 is automatically adjusted according to the adjustment value calculated by the error compensation model.

[0049] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
