Description

Technical Field

[0001] The utility model relates to the technical field of self-service car washing, in particular to a self-service car washing machine with a mechanical arm for scrubbing. Background Art

[0002] The cleaning workflow of the contactless self-service car wash machine is very convenient. The car owner first drives into the designated area. The system automatically adjusts the car washing parameters after identifying the vehicle. Then, the car owner turns off the engine and windows, and selects a car wash option, such as basic car wash or comprehensive cleaning. The car wash machine first removes large dirt on the surface of the vehicle through water spray pre-treatment, and then performs high-pressure washing and foam washing to ensure that the stains are completely removed. Finally, the car wash machine automatically rinses off the residual foam and dries the vehicle surface to restore dryness. After the entire car washing process is completed, the car owner can start the engine and leave the car wash area.

[0003] While providing convenient and fast car washing services, contactless self-service car wash machines also face the challenge of insufficient cleaning effects. Due to their contactless design, when faced with stubborn stains on the car paint such as resin, bird droppings, chemicals, etc., the stickiness and chemical properties of these stains make it difficult for them to be completely removed by high-pressure water flow or foam cleaning. At the same time, due to the fixed settings of the car washing machine's nozzle position and water spray pressure, certain special areas on the vehicle surface such as the edges of the vehicle body and the roof may not be fully covered or have the ideal cleaning effect, thus affecting the overall car washing effect.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in 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 in 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.

[0032] Combination Figure 1-Figure 5 As shown, the utility model is a self-service car washing machine with mechanical arm scrubbing, comprising a frame 1 placed on the ground, wherein the frame 1 is also provided with a driving mechanism 2, a water flow and foam washing mechanism 3 and a drying mechanism 4, wherein under the drive of the driving mechanism 2, the water flow and foam washing mechanism 3 can perform water spray pretreatment, high pressure washing and foam washing on the vehicle surface to remove large pieces of dirt,

[0033] The base 5 is arranged on the water flow and foam washing mechanism 3, and can be displaced along the surface of the vehicle body under the driving of the driving mechanism 2;

[0034] A multi-axis robot arm 6 is disposed on the base 5 and can be displaced synchronously with the movement of the base 5;

[0035] The wiping mechanism 7 is arranged on the moving end of the multi-axis robot arm 6. It cooperates with the high-pressure flushing and foam cleaning of the water flow and foam flushing mechanism 3, and is driven by the driving mechanism 2 and the multi-axis robot arm 6. The wiping mechanism 7 can scrub various parts of the surface of the vehicle body, and then drive the drying mechanism 4 through the driving mechanism 2 to dry the vehicle surface.

[0036] When a car owner chooses to use this self-service car washing machine, he first drives the car into the designated car washing area. At this time, the system of the car washing machine starts to work. Under the drive of the driving mechanism 2, the water flow and foam flushing mechanism 3 first sprays water on the surface of the vehicle for pre-treatment, with the purpose of removing large pieces of dirt and dust on the surface of the vehicle. Then, the water flow and foam flushing mechanism 3 performs high-pressure flushing, using the high-pressure water flow to further flush the surface of the vehicle to remove more stubborn stains. Then, the foam cleaning agent is sprayed through the water flow and foam flushing mechanism 3, and the foam can penetrate deeper into the stains to assist cleaning. In this process, the base 5 is displaced along the surface of the vehicle body under the drive of the driving mechanism 2, and the multi-axis robot arm 6 is arranged on the base 5 and displaces synchronously. The wiping mechanism 7 is arranged on the multi-axis machine On the mobile end of the robotic arm 6, according to the control system instructions of the car washing machine, the water flow and foam washing mechanism 3 are cooperated with the washing and foam washing of the car body to scrub the surface of the car body. Due to the flexibility of the multi-axis robotic arm 6, the wiping mechanism 7 can cover every corner of the vehicle surface, including the edges of the vehicle body, the roof and other hard-to-reach areas. After the robotic arm scrubs, the stains on the vehicle surface are completely removed. At this time, the driving mechanism 2 drives the drying mechanism 4 to start working, and dries the vehicle surface to ensure that the vehicle surface is quickly restored to dryness. During the entire car washing process, various components work together under the drive of the driving mechanism 2, realizing a complete process from water spray pretreatment, high-pressure washing, foam washing, robotic arm scrubbing to drying treatment, greatly improving the car washing efficiency and cleaning effect.

[0037] It should be noted that the driving mechanism 2, the water flow and foam flushing mechanism 3 and the drying mechanism 4 are the same as the structures in the prior art, and have not been optimized in the present application and are not the key protection contents of the application document, so there is no need to elaborate on them again. In terms of electrical connection, the self-service car washing machine adopts a standardized electrical interface and connection method, and the various functional components are connected through electrical connectors such as cables and connecting plugs to realize power transmission and control signal exchange. The specific electrical connection method and control method are common knowledge of technicians in this field and there is no need to elaborate on them again.

[0038] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5As shown; the multi-axis robot 6 is a six-axis robot. In the self-service car washing machine system, the multi-axis robot 6 is a key component, and its design is directly related to the efficiency and effect of the car washing machine on the cleaning of the vehicle surface. In particular, when the multi-axis robot 6 is concretized as a six-axis robot, its working principle and advantages are more obvious. The six-axis robot is a highly flexible and programmable automation device, which consists of six joints or axes, each of which can rotate or move independently. This design enables the six-axis robot to achieve complex movement and positioning in three-dimensional space. During the operation of the self-service car washing machine, the six-axis robot is installed on the base 5, and the base 5 is displaced along the surface of the vehicle body under the drive of the driving mechanism 2. As the base 5 moves, the six-axis robot also moves synchronously, thereby ensuring that the wiping mechanism 7 can cover every corner of the vehicle surface.

[0039] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; the wiping mechanism 7 comprises:

[0040] The housing 71 is fixedly mounted on the moving end of the multi-axis robot arm 6, and serves as a protective shell and a supporting structure of the entire wiping mechanism. A rotating driving member 72 is disposed inside the housing 71 to provide power for the rotation of the cleaning cloth 74. The rotating driving member 72 is a core component of the wiping mechanism 7, and is specifically a servo motor or other rotating driver;

[0041] The mounting seat 73 is fixedly mounted on the output end of the rotation driving member 72 and can rotate axially under the drive of the rotation driving member 72;

[0042] The cleaning cloth 74 is detachably connected to the other side surface of the mounting seat 73. One side surface of the cleaning cloth 74 is in close contact with the vehicle body. Under the drive of the rotating driving member 72, the cleaning cloth 74 is rotated to wipe the vehicle body surface. When the car washing machine system starts to work, the multi-axis robot arm 6 is driven by the driving mechanism 2 to move the wiping mechanism 7 to the position of the vehicle surface that needs to be cleaned. At this time, the rotating driving member 72 starts to work and drives the mounting seat 73 to rotate axially. Since the cleaning cloth 74 is detachably connected to the mounting seat 73 and one side surface thereof is in close contact with the vehicle body, the cleaning cloth 74 is rotated to wipe the vehicle body surface. The vehicle body fits tightly, so as the mounting base 73 rotates, the cleaning cloth 74 will also rotate synchronously, thereby achieving rotational wiping of the vehicle body surface. Compared with traditional linear wiping or reciprocating wiping, this rotational wiping method has higher cleaning efficiency and better cleaning effect, because rotational wiping can make more fibers of the cleaning cloth 74 contact with the vehicle body surface, increasing friction, thereby more effectively removing stains and dirt. At the same time, due to the rotation of the cleaning cloth 74, the cleaning liquid or foam can be more evenly distributed on the vehicle body surface, thereby improving the uniformity and consistency of cleaning.

[0043] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; a Velcro hook surface is fixedly installed on the surface of one side of the mounting seat 73 away from the driving end of the rotating driving member 72, which is usually a series of closely arranged small hooks, and a Velcro fur surface that matches the Velcro hook surface is fixedly installed on one side of the cleaning cloth 74, which is usually a soft fiber or fabric that can fit tightly with the hook of the Velcro hook surface, wherein the cleaning cloth 74 is connected to the mounting seat 73 through the Velcro hook surface and the Velcro fur surface. When the cleaning cloth 74 needs to be installed, the user only needs to align and fit the side of the cleaning cloth 74 with the Velcro hook surface on the mounting seat 73. Since there is a strong bond between the hook on the Velcro hook surface and the fiber or fabric on the Velcro fur surface Due to the strong adhesion, the cleaning cloth 74 will be firmly fixed on the mounting base 73. When the cleaning cloth 74 becomes dirty or worn due to long-term use, the user can simply tear off the Velcro connection to easily remove the cleaning cloth 74 from the mounting base 73 and then replace it. This design greatly improves the convenience and efficiency of replacing the cleaning cloth. Quick replacement: Using the Velcro connection, the process of replacing the cleaning cloth becomes very simple and quick, without the use of any tools or complicated operating steps. At the same time, the Velcro connection has a strong adhesive force, which can ensure that the cleaning cloth 74 is driven by the rotating driving component 72 to closely fit the surface of the vehicle body for rotational wiping, thereby avoiding the loosening or falling off of the cleaning cloth during work.

[0044] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5 As shown; the cleaning cloth 74 is composed of a circular rubber seat and a scouring pad, wherein a Velcro fleece surface is fixedly mounted on one side surface of the circular rubber seat, and a scouring pad is fixedly mounted on the other side surface of the circular rubber seat. The circular rubber seat is the bottom structure of the cleaning cloth 74, and it has a flat circular bottom surface that matches the contact surface of the mounting seat 73, and a Velcro fleece surface is fixedly mounted on one side surface of the circular rubber seat for connecting with the Velcro hook surface on the mounting seat 73. The scouring pad is a commonly used cleaning material with excellent cleaning ability and durability. The scouring pad is fixedly mounted on the other side surface of the circular rubber seat, directly It contacts the surface of the vehicle body to perform cleaning work. When the multi-axis robot arm 6 moves the wiping mechanism 7 to the position of the vehicle surface that needs to be cleaned, the cleaning cloth 74 on the mounting seat 73 will fit tightly with the surface of the vehicle body. Driven by the rotating driving component 72, the mounting seat 73 rotates axially, driving the cleaning cloth 74 to rotate together. At this time, the scouring pad will produce relative movement with the surface of the vehicle body, using its excellent cleaning ability to remove stains and dirt. At the same time, the elastic design of the circular rubber seat enables the cleaning cloth 74 to better adapt to the curvature change of the vehicle body surface, ensuring that the cleaning cloth 74 can fit tightly to the surface of the vehicle body and improve the cleaning effect.

[0045] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 5As shown; the drying mechanism 4 is integrally arranged in a "冂" shape, and an intelligent recognition camera 8 is also arranged on the drying mechanism 4. The drying mechanism 4 is integrally designed in a "冂" shape. This structure allows it to cover the vehicle body from above and both sides, thereby achieving a wider and more uniform drying effect. Usually, the drying mechanism 4 will include multiple hot air outlets, and the hot air is blown out to evaporate the moisture on the vehicle body surface. In the car wash process, after the vehicle is washed, the multi-axis robotic arm 6 will guide the vehicle to the lower part of the drying mechanism 4. At this time, the drying mechanism 4 will be activated, and hot air will be blown out through the hot air outlets to quickly evaporate the moisture on the vehicle body. The intelligent recognition camera 8 is installed on the drying mechanism 4, and its main function is to identify the dirt on the vehicle body surface. The intelligent recognition camera 8 takes real-time images of the vehicle body surface and uses image processing technologies and algorithms to identify the dirt areas such as stains and mud spots on the vehicle body surface. These recognition results will be transmitted to the control system. The control system will analyze these data and formulate subsequent cleaning strategies based on them. Among them, these recognition and control systems are well-known technologies in the prior art and can be obtained through Internet retrieval. The specific recognition process and recognition method will not be elaborated again. There is a close linkage relationship between the intelligent recognition camera 8 and the wiping mechanism 7. When the intelligent recognition camera 8 identifies the dirt areas on the vehicle body surface, the control system will send this information to the wiping mechanism 7. During the cleaning process, the wiping mechanism 7 will focus on cleaning these dirt areas according to this information to ensure that the vehicle body surface is thoroughly cleaned. This linkage method enables the self-service car wash machine to more intelligently identify and process the dirt on the vehicle body surface, improving the car wash efficiency and cleaning quality. In summary, by designing the drying mechanism 4 in a "冂" shape and equipping it with an intelligent recognition camera 8, the functions of efficient drying of the vehicle body surface and intelligent dirt recognition are realized. The intelligent recognition camera 8 can identify the dirt on the vehicle body surface and transmit this information to the wiping mechanism 7, enabling it to focus on cleaning these areas, improving the intelligence level and cleaning effect of the car wash machine.

[0046] In a preferred embodiment of the present utility model, it can be further configured as: As Figures 1 to 5As shown; there are several intelligent recognition cameras 8, wherein the number of intelligent recognition cameras 8 is equally divided into three groups, which are respectively distributed on the three surfaces of the drying mechanism 4. The shooting end of the intelligent recognition camera 8 is aimed at the vehicle surface. This layout ensures that the intelligent recognition camera 8 can fully cover the vehicle surface and capture images of the vehicle surface from multiple angles and positions. The shooting end of each intelligent recognition camera 8 is accurately aimed at the vehicle surface. When the vehicle enters the car washing machine system and parks at the designated position, the intelligent recognition camera 8 starts working and captures images of the vehicle surface in real time. These images are then transmitted to the image processing unit in the control system for processing and analysis. The image processing unit uses advanced algorithms and technologies to process the images captured by the intelligent recognition camera 8, which includes steps such as removing noise, enhancing image contrast, and detecting edges and features. Through these processes, the image processing unit can identify dirt, stains and other unclean areas on the vehicle surface. Once the image processing unit identifies the dirt on the vehicle surface Dirt area, it transmits this information to the control system, and the control system then adjusts the working strategy and parameters of the wiping mechanism 7 according to this information. For example, the control system may instruct the wiping mechanism 7 to focus on cleaning a specific dirt area, or adjust the wiping force and speed to obtain a better cleaning effect. Since the intelligent recognition cameras 8 are equally divided into three groups and distributed on the three surfaces of the drying mechanism 4, they can work together to provide more comprehensive and accurate recognition results. The intelligent recognition cameras 8 at different positions can capture images of the vehicle surface from different angles and positions, thereby capturing more details and features. These image information are comprehensively processed and analyzed to improve the accuracy and reliability of recognition. By distributing the intelligent recognition cameras 8 in the dependent claims on the three surfaces of the drying mechanism 4 and allowing them to work together to identify dirt on the vehicle surface, the self-service car washing machine system can achieve a smarter and more precise cleaning process. This design not only improves the efficiency and quality of car washing, but also improves the user experience and satisfaction.

[0047] The specific working principle of the utility model of a self-service car washing machine with mechanical arm scrubbing is as follows:

[0048] Pretreatment and flushing:

[0049] Driven by the driving mechanism 2, the water flow and foam washing mechanism 3 first sprays water on the vehicle surface for pretreatment to remove floating dust and loose dirt on the surface. Then, the water flow and foam washing mechanism 3 performs high-pressure washing to deeply clean the stubborn stains on the vehicle body surface with high-pressure water flow. Subsequently, foam washing is performed to further improve the cleaning effect by spraying foam cleaning agent and coordinating with water flow.

[0050] Robotic arm scrubbing:

[0051] During the rinsing process, the base 5 is displaced along the vehicle body surface under the drive of the driving mechanism 2 to ensure that the car wash machine can cover the entire vehicle body. The multi-axis robotic arm 6 installed on the base 5 is displaced synchronously with the movement of the base 5, so as to achieve precise scrubbing of different positions on the vehicle body. The wiping mechanism 7 includes a housing 71, a rotation driving member 72, a mounting seat 73 and a cleaning cloth 74. The rotation driving member 72 drives the mounting seat 73 to rotate axially, and then drives the cleaning cloth 74 to rotate. Through the close fit and rotational movement of the cleaning cloth 74 with the vehicle body surface, the scrubbing of the vehicle body surface is realized. The cleaning cloth 74 is composed of a circular rubber seat and a scouring pad. The hook surface of the magic tape on the circular rubber seat cooperates with the loop surface of the magic tape on the mounting seat 73 to realize the detachable connection of the cleaning cloth 74. This design facilitates the user to replace the cleaning cloth 74 and ensures the durability of the car wash effect. There is also an intelligent recognition camera 8. These cameras are divided into three groups and are respectively installed on the three surfaces of the drying mechanism 4, with the shooting ends facing the vehicle surface. After the intelligent recognition camera 8 can identify the dirt on the vehicle body surface, the control system will send this information to the wiping mechanism 7. During the cleaning process, the wiping mechanism 7 will focus on cleaning these dirt areas according to this information to ensure that the vehicle body surface is thoroughly cleaned;

[0052] Drying treatment:

[0053] After scrubbing, the driving mechanism 2 drives the drying mechanism 4 to perform drying treatment on the vehicle surface. The drying mechanism 4 is integrally arranged in an inverted U shape and can dry the vehicle body to ensure that the vehicle body dries quickly and evenly;

[0054] During the entire car wash process, each component works in coordination under the precise control of the driving mechanism 2, realizing comprehensive, efficient and intelligent cleaning of the vehicle surface. This self-service car wash machine not only improves the car wash efficiency, but also provides users with a more convenient and comfortable car wash experience.

[0055] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
