Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically an automatic cleaning device. Background Technology

[0002] In machining, parts manufacturing, and related industrial production, racks are a common mechanical transmission component, and their surface cleaning is crucial. During processing, handling, and use, racks easily accumulate dust, oil, metal shavings, and other impurities. If these impurities are not cleaned promptly, they can lead to accelerated wear, decreased transmission accuracy, and even equipment malfunctions, severely impacting production efficiency and product quality. However, traditional rack cleaning methods rely heavily on manual operation, which is not only inefficient and labor-intensive but also struggles to guarantee uniformity and consistency in cleaning results. Furthermore, manual cleaning often fails to thoroughly clean the complex tooth structure of racks, easily missing hard-to-reach areas and leaving impurities behind. While some existing automated cleaning equipment can achieve certain cleaning functions, they often lack specificity and cannot adapt to the unique structure of racks, failing to efficiently complete integrated cleaning operations such as sweeping, air blowing, and impurity removal. Therefore, developing an automated device specifically for cleaning racks that can efficiently and thoroughly remove impurities from the rack surface and tooth grooves, while also being simple in structure, easy to operate, and cost-controllable, is of great practical significance for ensuring the transmission performance of racks, extending their service life, and improving the operational reliability of related mechanical systems.

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0014] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0016] To effectively solve the aforementioned technical problems, this utility model provides a reasonably structured, clean, and efficient automatic cleaning device, such as... Figure 1-3As shown, the core components of the device include a worktable 1. On the worktable 1, a transmission drive mechanism 2, a cleaning mechanism 3, and an air blowing mechanism 4 are systematically integrated. The core function of the transmission drive mechanism 2 is to drive the rack to move stably and continuously along the X-axis and to make it accurately pass through the working areas of the cleaning mechanism 3 and the air blowing mechanism 4 in sequence. The design of the cleaning mechanism 3 is particularly crucial. It comprises two functionally independent brush assemblies: a first brush assembly and a second brush assembly. The first brush assembly consists of two rotatable first brushes 31 arranged parallel to each other along the Y-axis, forming the first cleaning station between the two brushes. The second brush assembly consists of two rotatable second brushes 32 arranged parallel to each other along the Z-axis, also forming the second cleaning station. This unique multi-axial brush layout gives the device the ability to perform all-round, multi-angle deep cleaning of the rack, ensuring that all surfaces of the rack are effectively brushed throughout its journey along the X-axis. In addition, the separate first and second cleaning stations not only make the cleaning process clear and the sequence controllable, but also greatly facilitate the real-time monitoring and refined management of the entire cleaning process.

[0017] In a preferred embodiment of this utility model, the transmission drive mechanism 2 mainly includes a first drive motor 21, a drive shaft 22, a gear disk 23, and a drive gear 24. The first drive motor 21 is stably installed at the bottom of the workbench 1, and its power output end is directly connected to the drive shaft 22. The drive gear 24 is coaxially fixed with the drive shaft 22 and precisely meshes with the rack to be cleaned. The first drive motor 21 provides precise and controllable rotational power, which is transmitted to the drive gear 24 via the drive shaft 22, and finally converted into a smooth and reliable linear motion of the rack along the X direction. This transmission method not only ensures the stability of the rack's movement trajectory and the consistency of its speed, providing a precise positioning basis for subsequent cleaning processes, but also significantly improves the overall cleaning efficiency and the accuracy of the processing results. More importantly, this automated transmission design allows the main processes of the rack to be carried out automatically, greatly reducing the physical exertion and intervention requirements of the operators. Workers only need to assist in completing the end feed, effectively reducing labor intensity and improving the automation level of the equipment.

[0018] Furthermore, the cleaning mechanism 3 is equipped with two independent rotary drive components, which are responsible for driving the first brush assembly 31 and the second brush assembly 32 to rotate efficiently, respectively. Each rotary drive component consists of a second drive motor 33 and a set of synchronous belt drive components 34. Specifically, there are two second drive motors 33, each of which is connected to and drives the corresponding first brush 31 or second brush 32 through its dedicated synchronous belt drive component 34. This design gives the first brush 31 and the second brush 32 the ability to rotate independently, so that the speed, direction and even start and stop of the brush can be flexibly adjusted according to the cleaning needs of the rack, which greatly enhances the adaptability and customizability of the cleaning process. At the same time, each set of synchronous belt drive components 34 ensures the rotational synchronization between two brushes in the same group or between individual brushes, thereby ensuring a high degree of coordination and uniformity in the cleaning action of the brush and rack contact surface, avoiding cleaning omissions or uneven effects caused by speed differences.

[0019] To ensure precise positioning and stable operation of the rack during the cleaning process, this device is specially designed with a limiting plate 5 and a guide plate 6. These two plates are mounted opposite each other on the worktable 1, and the narrow gap between them forms the standard channel for the rack's movement. The limiting plate 5 and the guide plate 6 work together to effectively constrain the rack laterally, ensuring that it moves strictly along the preset X-axis trajectory. This effectively prevents possible deviation, vibration, or jumping during high-speed movement or under cleaning force, thus ensuring the consistency of cleaning effect and the reliability of equipment operation. It is worth noting that the guide plate 6 has an oblong hole, through which bolts are used to fix it to the worktable 1. The oblong hole design provides valuable adjustment margin, allowing for fine-tuning of the position of the guide plate 6 relative to the limiting plate 5 during installation or maintenance to accommodate racks of different specifications or compensate for assembly tolerances. The bolt tightening ensures that the guide plate 6 is firmly locked after adjustment, significantly enhancing the rigidity of the overall structure and the long-term stability of the equipment.

[0020] In this embodiment, it is further preferred that the workbench 1 is also provided with a positioning post, which is installed at the entrance of the channel. The positioning post is fitted with a guide wheel 7. The cooperation between the positioning post and the guide wheel 7 provides smooth guidance for the rack and reduces the resistance of the rack when entering the cleaning station.

[0021] The air blowing mechanism 4 serves as the final stage of the cleaning process, employing a multi-angle coverage strategy. This mechanism comprises a first air knife 41 and a second air knife 42. The first air knife 41 is securely mounted above the workbench 1 via a dedicated support frame, with its air outlet precisely positioned vertically downwards, primarily targeting the top surface and tooth groove area of ​​the rack. The second air knife 42 is horizontally arranged and fixed at an appropriate position on the workbench 1, with its airflow direction mainly targeting the sides and ends of the rack. This three-dimensional layout combining vertical and horizontal elements enables powerful, multi-angle, and thorough cleaning of the rack without any blind spots. The air knife technology itself generates a high-speed, concentrated airflow jet, and its powerful impact can completely strip away and remove fine dust, debris, oil, and other impurities that remain or are loose after the initial brush cleaning. This step is crucial for ensuring that the rack reaches a high cleanliness standard, significantly improving the final cleaning quality and providing a reliable cleaning foundation for subsequent processes (such as inspection, painting, and assembly).

[0022] To efficiently handle dust generated during the cleaning process and maintain the cleanliness of the work area, this invention features a vacuum cleaner 8 specifically designed for use beneath the workbench 1. The vacuum cleaner's suction port is optimized and precisely installed directly onto the workbench 1 (located below the sweeping mechanism 3 and the blowing mechanism 4). The core function of the vacuum cleaner 8 is to actively and continuously suck up and collect dust, particulate matter, and blown-out impurities generated and stirred up by the brush cleaning and air knife blowing processes.

[0023] In this embodiment, it is further preferred that the bottom of the workbench 1 is also provided with a dust collection hood 9. The dust collection hood 9 helps to collect dust and impurities during the cleaning process, which is convenient for subsequent processing and maintenance.

[0024] It is worth noting that the technical features of the air knife, motor, vacuum cleaner, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0025] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
