Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a robotic cleaning device for point-spraying. Background Technology

[0002] Robotic cleaning equipment is widely used in modern industrial manufacturing, especially in the cleaning of precision workpieces such as automotive parts and electronic components, where automated robotic cleaning plays an important role.

[0003] To achieve precise cleaning of complex surfaces and specific contamination points on workpieces, existing cleaning devices often employ high-pressure jetting. In automated processes, this typically manifests as "point-to-point spraying," where the control system frequently starts and stops power components (such as extraction pumps) to control the nozzles to perform intermittent or pulsed spraying on specific areas.

[0004] However, this frequent start-stop operation mode presents a serious technical problem. When the power unit stops working and the water pressure disappears momentarily, the water remaining in the nozzles, connecting hoses, and outlet pipes is prone to backflow under the influence of gravity or pipeline pressure differential. This backflowing water will impact the power unit, especially the impeller of the extraction pump or the valve body. Over time, this can lead to wear, damage, or even failure of the power unit, significantly reducing the reliability and service life of the entire cleaning device.

[0005] Therefore, this invention proposes a robotic cleaning device with fixed-point spraying to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problem that in the existing technology of fixed-point spraying robotic cleaning devices, when the power component is frequently started and stopped, the water flow in the pipeline is prone to backflow, which can impact and damage the power component and lead to low reliability of the device, this utility model aims to provide a fixed-point spraying robotic cleaning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a robotic cleaning device for fixed-point spraying, comprising: a supporting water tank; a robotic arm; an adjusting component slidably connected to the upper part of the supporting water tank and used to drive the robotic arm to move above the supporting water tank; a detection head fixedly connected to the end of the robotic arm and used to scan the object to be cleaned; and a control board electrically connected to the robotic arm, the adjusting component, the detection head, and the fixed-point spraying mechanism; the fixed-point spraying mechanism includes a nozzle, a power component, and a connecting water pipe, wherein the outlet of the power component is connected to one end of the connecting water pipe, and the other end of the connecting water pipe is connected to the nozzle.

[0008] In addition, there are support columns, limit plates, support plates, T-shaped push columns, and telescopic springs.

[0009] The support column is set vertically, and the nozzle is fixedly connected to the top of the support column;

[0010] Furthermore, the limiting plate and the support plate are fixedly installed inside the connecting water pipe; the T-shaped push column is slidably installed inside the connecting water pipe, and the T-shaped push column is located between the limiting plate and the support plate; the telescopic spring is installed inside the connecting water pipe, and the telescopic spring is sleeved on the column body of the T-shaped push column, with the two ends of the telescopic spring abutting against the support plate and the T-shaped push column respectively.

[0011] This limiting plate is used to block the T-shaped push column when the power unit stops working, thereby sealing the water passage connecting the water pipe.

[0012] Preferably, the adjustment assembly includes drive slide rails a and b arranged perpendicularly to each other. The robotic arm is slidably connected to drive slide rails a and b via corresponding sliders. This dual-slide rail structure enables the robotic arm to perform two-dimensional planar movement above the supporting water tank, thus expanding the working range.

[0013] Preferably, the power unit includes an extraction pump and an outlet pipe. The inlet of the extraction pump is connected to the supporting water tank to extract the cleaning fluid from the tank, and the outlet of the extraction pump is connected to the connecting water pipe through the outlet pipe to provide a continuous and high-pressure power source for targeted spraying.

[0014] Preferably, the fixed-point spraying mechanism also includes a connecting hose. One end of the connecting hose is connected to the downstream end of the T-shaped push column of the connecting water pipe, and the other end is connected to the nozzle. Using a connecting hose facilitates installation and wiring, and can effectively buffer the water pressure pulse generated when the pump starts.

[0015] Preferably, the supporting water tank has a chute. The robotic arm is used to feed the object into the supporting water tank via the chute for immersion. A partition is fixedly installed inside the supporting water tank to separate the immersion area from the spraying area, preventing the wastewater from spraying from contaminating the clean water used for immersion.

[0016] Preferably, the device further includes a protective mechanism connected to the inlet of the supporting water tank. The protective mechanism includes a connecting pipe, a threaded pipe, a filter plate, and a filter membrane. The threaded pipe is coaxially fitted outside the connecting pipe, and the filter plate and filter membrane are housed inside the threaded pipe, for achieving dual filtration of the incoming water source. The structure of the threaded pipe facilitates quick disassembly and replacement of the filter element.

[0017] In a further preferred embodiment, the protective mechanism also includes a sealing gasket. This sealing gasket is placed at the connection between the connecting pipe and the threaded pipe, and the tightening force of the threaded pipe is used to press the sealing gasket to prevent water leakage at the connection between the connecting pipe and the threaded pipe, thus ensuring the airtightness of the water inlet pipe.

[0018] Preferably, the bottom of the supporting water tank is also connected to a water outlet pipe. This water outlet pipe is used to discharge wastewater from the supporting water tank, and a control valve is installed on the outside of the water outlet pipe to facilitate manual or automatic control of the timing and flow rate of wastewater discharge.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting a nozzle fixedly connected by a support column, and cooperating with a robotic arm that can move on the adjustment component and is controlled by the control board and the detection head, allows the robotic arm to grasp the object and rotate it in front of the fixed nozzle. This solves the problem that the existing cleaning device has a simple structure and cannot spray the object from multiple angles and all directions. It achieves the effect of precise point-to-point and multi-face rotational spraying of the object, improving the flexibility and coverage of the cleaning process.

[0021] 2. This utility model solves the problem in the prior art where water easily flows back into the pipeline after the jet stops, thus damaging the power components such as the pump, by setting a mechanical valve structure consisting of a T-shaped push column, a limiting plate, a support plate, and a telescopic spring inside the connecting water pipe. It achieves the effect of automatically closing the water path by using the spring force to push the T-shaped push column to reset and being limited by the limiting plate when the power components stop working, effectively preventing water backflow and protecting the power components.

[0022] 3. This utility model solves the problems of low automation, scattered functions, and cumbersome operation in the prior art by organically combining the control board, detection head, adjustment components and robotic arm. It achieves the effect of automatic scanning and identification, grasping, soaking and fixed-point spraying of objects in an integrated manner, and improves the automation level of the device and the convenience and stability of cleaning.

[0023] 4. This utility model, by setting up a protective mechanism, which contains a filter plate and a filter membrane, solves the problem of impure water quality containing impurities and dust, which affects the cleaning effect or clogs the nozzle. It achieves the effect of dual filtration and purification of the water source entering the support water tank, ensuring the cleanliness of the cleaning water, and the mechanism is easy to disassemble and replace.

[0031] Example:

[0032] Reference Figures 1 to 5 This utility model provides a robot cleaning device for point spraying, which aims to solve the problem that existing robot cleaning devices cannot perform all-round point spraying on objects and that water is prone to backflow and damage to the power component 45 after the spraying stops.

[0033] like Figure 1 As shown, the fixed-point spraying robotic cleaning device includes a supporting water tank 1, which serves as the mounting base for the entire device and contains cleaning water. An adjustment component 43 is slidably connected to the upper part of the supporting water tank 1. The adjustment component 43 is used to drive the robotic arm 3 to move above the supporting water tank 1. A detection head 44 is fixedly connected to the end of the robotic arm 3. The detection head 44 is used to scan the object to be cleaned to obtain position information. The device also includes a control board 2, which is electrically connected to the robotic arm 3, the adjustment component 43, the detection head 44, and the fixed-point spraying mechanism 4. The control board 2 is used to coordinate and control the automated operation of the above components. The fixed-point spraying mechanism 4 is used to perform the final spraying cleaning operation.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The fixed-point spraying mechanism 4 includes a power unit 45, a connecting water pipe 46, a connecting hose 42, a nozzle 41, and a support column 412.

[0035] The power assembly 45 includes a pump 451 and an outlet pipe 452. The outlet of the pump 451 is connected to the connecting water pipe 46 through the outlet pipe 452, and the inlet of the pump 451 is connected to the supporting water tank 1.

[0036] The top of the vertically set support column 412 is fixedly connected to the nozzle 41. This structure fixes the position of the nozzle 41 so that the robotic arm 3 can grab the object and cooperate with the nozzle 41 to perform fixed-point cleaning.

[0037] A limiting plate 48 and a support plate 47 are fixedly installed inside the water pipe 46; a T-shaped push column 49 is also slidably installed inside the water pipe 46, and the T-shaped push column 49 is located between the limiting plate 48 and the support plate 47; a telescopic spring 410 is also installed inside the water pipe 46, and the telescopic spring 410 is sleeved on the column of the T-shaped push column 49, and the two ends of the telescopic spring 410 abut against the support plate 47 and the T-shaped push column 49 respectively; when the power component 45 stops working, the telescopic spring 410 pushes the T-shaped push column 49 to reset, and the limiting plate 48 blocks it, so as to close the water passage of the water pipe 46 and prevent water backflow.

[0038] One end of the connecting hose 42 is connected to the downstream end of the T-shaped push column 49 of the connecting water pipe 46, and the other end of the connecting hose 42 is connected to the nozzle 41. The connecting hose 42 is used to buffer water pressure and provide a flexible connection.

[0039] As a preferred embodiment, please refer to Figure 1 The adjustment component 43 includes a drive slide rail a431 and a drive slide rail b432 arranged perpendicularly to each other. The robotic arm 3 is slidably connected to the drive slide rail a431 and the drive slide rail b432. This arrangement enables the two-dimensional planar movement of the robotic arm 3.

[0040] As a preferred embodiment, please refer to Figure 1 The power assembly 45 includes a pump 451 and an outlet pipe 452. The outlet of the pump 451 is connected to the connecting water pipe 46 through the outlet pipe 452, and the inlet of the pump 451 is connected to the supporting water tank 1 for pumping water from the supporting water tank 1.

[0041] As a preferred embodiment, please refer to Figure 1 and Figure 4 The fixed-point spraying mechanism 4 also includes a connecting hose 42. One end of the connecting hose 42 is connected to the downstream end of the T-shaped push column 49 of the connecting water pipe 46, and the other end of the connecting hose 42 is connected to the nozzle 41 for flexibly supplying water to the nozzle 41.

[0042] As a preferred embodiment, please refer to Figure 1The support water tank 1 is provided with a slide 411. The robotic arm 3 is used to send objects into the support water tank 1 through the slide 411. The support water tank 1 is fixedly provided with a partition plate 413 to separate the soaking area and the spraying area.

[0043] As a preferred embodiment, please refer to Figure 1 and Figure 5 The device also includes a protective mechanism 5, which is connected to the inlet of the supporting water tank 1. The protective mechanism 5 includes a connecting pipe 51, a threaded pipe 52, a filter plate 54, and a filter membrane 55. The threaded pipe 52 is coaxially fitted outside the connecting pipe 51, and the filter plate 54 and the filter membrane 55 are housed inside the threaded pipe 52 for filtering the water entering the supporting water tank 1.

[0044] As a further optimization of protective mechanism 5, please refer to Figure 5 The protective mechanism 5 also includes a sealing gasket 53, which is disposed at the connection between the connecting pipe 51 and the threaded pipe 52 to prevent water leakage at the connection between the connecting pipe 51 and the threaded pipe 52.

[0045] As another preferred option for supporting water tank 1, please refer to Figure 1 The bottom of the supporting water tank 1 is also connected to a water outlet pipe 6, which is used to discharge the wastewater in the supporting water tank 1. A control valve is installed on the outside of the water outlet pipe 6 to control the discharge of wastewater.

[0046] The working principle is as follows:

[0047] First, external water enters through the protective mechanism 5. The water flows sequentially through the connecting pipe 51, the filter plate 54, and the filter membrane 55. Under the sealing effect of the sealing gasket 53, it undergoes double filtration and purification before entering the supporting water tank 1. The control board 2 serves as the control core, coordinating the operation of each component. When wastewater needs to be discharged, the control valve outside the outlet pipe 6 is opened.

[0048] When the cleaning task begins, the control panel 2 issues a command to adjust the drive rails a 431 and b 432 of the adjustment component 43, driving the robotic arm 3 to move to the target position. The detection head 44 at the end of the robotic arm 3 scans the object to be cleaned to obtain its position information. Based on the detection information, the robotic arm 3 grasps the object and sends it into the soaking area separated by the partition plate 413 through the slide 411 on the support tank 1 for preliminary treatment. Subsequently, the robotic arm 3 grasps the object and moves it to the front of the nozzle 41 fixed by the vertically set support column 412. The robotic arm 3 rotates the object, cooperating with the fixed nozzle 41 to achieve multi-angle fixed-point spray cleaning of the object.

[0049] During spraying, control panel 2 activates the extraction pump 451 in power assembly 45. Pump 451 draws water from support tank 1, and the water flows through outlet pipe 452 into connecting water pipe 46. The water pressure inside connecting water pipe 46 increases, overcoming the elastic force of extension spring 410 and pushing T-shaped push column 49 away from the obstruction of limit plate 48. The water path is opened, and the water continues to flow through T-shaped push column 49, through connecting hose 42, and finally is sprayed out at high pressure from nozzle 41.

[0050] When the spraying task is completed, control panel 2 stops the operation of pump 451. The water pressure in the connecting water pipe 46 disappears rapidly. At this time, the telescopic spring 410, supported by support plate 47, rebounds, pushing the T-shaped push column 49 to reset until the T-shaped push column 49 is blocked again by limit plate 48, and the water path is closed. Through the synergistic action of T-shaped push column 49, limit plate 48, support plate 47 and telescopic spring 410, water in connecting hose 42 and nozzle 41 is effectively prevented from flowing back into connecting water pipe 46, thereby protecting pump 451 from damage and solving the problem of water backflow in the prior art.
