Description

Technical Field

[0001] The utility model relates to the technical field of laser navigator leveling, in particular to a leveling device for an AGV laser navigator in a high-temperature and high-humidity environment. Background Art

[0002] Currently, some high-quality wineries have automated the koji-making process. The process generally involves placing the koji blocks produced by the koji-making machine on a koji rack and then moving them to the koji room for fermentation. Once fermentation is complete, the blocks are removed from the rack, placed on pallets, bundled, and packaged for storage. This indicates that the koji-making process requires constant movement of blocks between different steps.

[0003] A relatively new approach is to install a laser navigation system on an AGV, enabling it to follow a defined path and transport the prepared blocks between different production processes. Laser navigation systems offer precise positioning and flexible, adaptable paths, adapting to a variety of on-site environments. This has led to their widespread use in the smart brewing industry. However, to ensure accurate positioning, the laser navigation system must remain level with the horizontal surface, so it must be adjusted before use.

[0004] Currently, the main method for leveling laser navigators is to install gaskets of varying thicknesses on the bottom of the laser navigator for leveling. This leveling method is cumbersome, time-consuming, and labor-intensive. Furthermore, due to the thickness of the gaskets, leveling can only be performed at intervals, rather than continuously fine-tuning, making the leveling operation difficult. Furthermore, the high temperature and humidity in the brewery and koji fermentation room can cause water mist to form on the mirror surface of the laser navigator. Laser navigators rely on the principle of optical refraction for positioning. Once water mist appears on the mirror surface, it will seriously affect the light transmittance of the laser navigator and cause laser refraction deviation, resulting in large deviations in the positioning accuracy of the AGV when moving and stopping. In more serious cases, the AGV may lose its navigation and stop operating. Utility Model Content

[0005] In view of the technical problems that the existing laser navigator leveling method is time-consuming, labor-intensive, difficult, and water mist affects the precise positioning of the laser navigator, the utility model provides a leveling device for AGV laser navigator in high temperature and high humidity environment.

[0006] The technical solution adopted by the present utility model is: a leveling device for an AGV laser navigator in a high temperature and high humidity environment, including an AGV trolley and a leveling assembly arranged on the AGV trolley door frame, the leveling assembly including a leveling bracket, a base is provided on the leveling bracket, and a leveling plate is provided above the base at intervals, the laser navigator is set on the leveling plate, the leveling plate is a square structure, the four corners of the leveling plate are threadedly connected to the base by bolts, and the base is provided with threaded holes matching the bolts.

[0007] Furthermore, a spring is provided on the surface of the bolt between the adjustment plate and the base.

[0008] Furthermore, a nut is provided at the end of the bolt passing through the base.

[0009] Furthermore, at least one heating fan is obliquely arranged on the leveling bracket and faces the laser navigator.

[0010] Furthermore, there are two heating fans, which are arranged on both sides of the laser navigator.

[0011] Furthermore, the leveling plate is an insulating plate.

[0012] The beneficial effects of the utility model are:

[0013] 1.

[0023] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0025] The following is combined with Figures 1 to 3 The utility model is further described.

[0026] Example 1

[0027] Aiming at the technical problems existing in the background technology, the utility model provides a leveling device for AGV laser navigation system in high temperature and high humidity environment. Figure 1 The leveling device includes an AGV trolley 1 and a leveling assembly 2 arranged on the door frame of the AGV trolley 1.

[0028] Specifically, refer to Figure 2 The leveling assembly 2 includes a leveling bracket 201, a base 202 is provided on the leveling bracket 201, an adjustment plate 203 is provided above the base 202, and the laser navigator 3 is provided on the adjustment plate 203. The adjustment plate 203 is a square structure, and the four corners of the adjustment plate 203 are threadedly connected to the base 202 through bolts 204. The base 202 is provided with threaded holes matching the bolts 204.

[0029] Working Principle: The laser navigator is mounted on a leveling plate. Leveling the plate also levels the laser navigator. During leveling, the bolts rotate within the screw holes in the base and the leveling plate by tightening them. Since the base is fixed to the leveling bracket, and the leveling plate is bolted to the base, tightening the bolts causes the leveling plate to move up and down, thereby leveling the laser navigator. Furthermore, since the leveling plate is bolted to the base, continuous fine-tuning of the plate is possible, resulting in high leveling accuracy and efficiency.

[0030] From the above structure and working principle, it can be seen that the utility model performs leveling operation on the laser navigator through a threaded manner, which not only has a fast leveling time and high leveling efficiency, but also can achieve continuous fine-tuning of the laser navigator, greatly reducing the leveling difficulty and improving the leveling accuracy.

[0031] The road surface in the brewery is inevitably uneven, which will cause the AGV to bump when driving. In the traditional leveling method using gaskets, the laser navigation system and the AGV are rigidly connected. Therefore, when the AGV is bumpy, the laser navigation system will also be bumped or vibrated. The laser navigation system is a relatively sophisticated device and is expensive. Bumps or vibrations will cause damage to the laser navigation system. Therefore, in order to protect the laser navigation system when the road surface is uneven, refer to Figure 3 In this embodiment, a spring 205 is also provided on the surface of the bolt 204 between the leveling plate 203 and the base 202. The spring not only supports the leveling plate, but also cushions the vibration of the leveling plate when the AGV encounters uneven road conditions. Consequently, the spring also cushions the vibration of the laser navigator, thereby protecting the laser navigator and preventing damage to the laser navigator due to vibration during the AGV's travel.

[0032] Reference Figure 3 In this embodiment, a nut 207 is also provided at the end of the bolt 204 passing through the base 202, and the nut plays a role of loosening.

[0033] During operation, the AGV may generate a weak current due to equipment charge or static electricity, which may flow into the laser navigation system and damage it. In addition, laser navigation systems are relatively sophisticated and expensive. Therefore, to prevent damage to the laser navigation system due to current flow, the adjustment plate 203 of this embodiment is made of an insulating plate.

[0034] Example 2

[0035] The background technology has mentioned that the high temperature and humidity in the winemaking workshop and the fermentation room of the koji blocks will cause water mist to appear on the mirror surface of the laser navigator. The laser navigator is based on the principle of optical refraction for positioning. Once water mist appears on the mirror surface, it will seriously affect the positioning accuracy of the laser navigator, causing the AGV to be unable to travel along the prescribed guide path. Deviations may occur during the driving process and may collide with the equipment next to it. Therefore, in response to the above technical problems, based on the first embodiment, with reference to Figure 2 In this embodiment, two heating fans 206 facing the laser navigator 3 are also tiltedly arranged on the leveling bracket 201.

[0036] Working principle: The heating fan itself does not have a heating function, but the heating fan itself and the side are equipped with power-consuming components, so it will generate some heat energy, thereby heating the air flowing through it. When the hot air is blown to the laser navigator, it can remove the water mist adsorbed on the mirror surface of the laser navigator, ensure that the mirror surface of the laser navigator is dry, and improve the feedback accuracy of the laser navigator, thereby ensuring the walking and stopping positioning accuracy of the AGV car, and ensuring the normal use of the laser navigator in a high temperature and high humidity environment.

[0037] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
