[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 4 As shown, a cleaning device includes a housing 1, a turntable 2, and a cleaning assembly 7. The housing 1 has independent cleaning chambers 11 and equipment chambers 12. The equipment chambers 12 are used to install various equipment required during the cleaning process, preventing water ingress and damage, and avoiding corrosion and short-circuit risks from water vapor and cleaning agents during the cleaning process. A worktable 4 extends horizontally from the housing 1, and the turntable 2 is rotatably connected to the worktable 4. The turntable 2 extends partially into the cleaning chambers 11 and divides the cleaning chambers 11 into interconnected rinsing chambers 111 and wastewater chambers 112. The turntable 2 transfers the workpiece between the cleaning chambers 11 and the outside of the housing 1.

[0021] In this embodiment, the workbench 4 is positioned near the center of the housing 1 along the vertical direction, extending outwards from the housing 1. A portion of the turntable 2 is located on the workbench 4. The turntable 2 on the workbench 4 serves as the loading and unloading mechanism for the cleaning process. The cleaning equipment can be seamlessly integrated into the entire automated production line as a single process, or the loading of workpieces to be cleaned and the unloading of cleaned workpieces can be performed manually.

[0022] The turntable 2 is provided with several positioning stations 21, which are arranged in a circular array on the turntable 2. Each positioning station 21 is provided with a positioning component for positioning a workpiece. Preferably, the positioning component is a clamp-type positioning structure (not shown in the figure). The clamp-type positioning structure includes a base, a positioning block, a clamping rod, and a pressure head. The base is fixed to the positioning station 21 of the turntable 2 as a basic carrier. The positioning block is installed on the base with an interference fit to form the initial positioning and support of the workpiece. The pressure head, made of non-metallic soft material, is connected to the clamping rod through threads or buckles. The clamping rod is connected to the base through a guide rail and is driven to move linearly by a linear module to transmit the clamping force to the end pressure head. This constrains the workpiece and, while ensuring the spatial posture stability of the workpiece, achieves dynamic load buffering and surface damage protection through the flexible material.

[0023] The top of the turntable 2 has an inlet 13 and an outlet 14 on the side wall of the box 1. The inlet 13 and the outlet 14 are both located on the movement trajectory of the positioning station 21 and are used to allow the workpiece to enter or leave the rinsing chamber 111.

[0024] The equipment chamber 12 includes an upper chamber 121, a transition chamber 122, and a lower chamber 123. In this embodiment, the cleaning equipment is divided into three layers vertically. The upper chamber 121 is located at the top layer, the rinsing chamber 111 and the transition chamber 122 are located in the middle layer, and the wastewater chamber 112 and the lower chamber 123 are located at the bottom layer. The turntable 2 is the dividing line between the middle layer and the bottom layer. The upper chamber 121, located at the top layer, is used to install electrical control equipment, avoiding electrical short circuits and equipment damage caused by condensation, accidental splashing, or leakage. The rinsing chamber 111, located in the middle layer, cleans the workpiece, and the generated wastewater flows to the wastewater chamber 112, located in the lower layer.

[0025] A solenoid valve 5 is installed in the lower chamber 123. The solenoid valve 5 is connected to the cleaning assembly 7 through a hose (not shown in the figure). The hose goes from the lower chamber 123 through the transition chamber 122 into the upper chamber 121 and finally connects to the cleaning assembly 7. Since the solenoid valve 5 will vibrate during operation, the vibration, heat and water vapor are mainly concentrated in the middle and lower parts, which are completely separated from the upper precision electronic control environment, thus improving the reliability and stability of the overall structure.

[0026] The housing 1 is provided with a partition 15 for separating the cleaning chamber 11 and the equipment chamber 12. The partition 15 is bent and fixed to the inner wall of the housing 1 to ensure that the equipment chamber 12 in the cleaning chamber 11 are independent of each other.

[0027] Specifically, the partition 15 includes a first plate 151, a second plate 152, a third plate 153, and a fourth plate 154 connected in sequence. The first plate 151 is arranged horizontally, serving as the interface between the upper chamber 121 and the flushing chamber 111. The second plate 152 is arranged vertically to separate the flushing chamber 111 and the transition chamber 122. The third plate 153 is arranged at an angle downwards to guide the wastewater flowing from the flushing chamber 111 to the designated wastewater chamber 112 for collection, reducing the risk of secondary pollution caused by wastewater retention or splashing. The fourth plate 154 is distributed vertically to fixally connect the third plate 153 and the bottom surface of the housing 1, providing a sturdy vertical support for the inclined third plate 153 and firmly connecting the lower end of the third plate 153 to the bottom surface of the housing 1, forming a stable support structure. The third plate 153 and the fourth plate 154 separate the wastewater chamber 112 and the lower chamber 123. The wastewater chamber 112 is located in the space of the box 1 below the workbench 4, while the lower chamber 123 is located in the space of the box 1 below the third plate 153. That is, the lower chamber 123 is located vertically below the flushing chamber 111. This allows the partition 15 to serve as part of the main load-bearing and support structure of the equipment within the box 1, and its inclined surface naturally guides the flow of wastewater without the need for additional guide channels. It also isolates the solenoid valve 5 from the wastewater, achieving multiple functions with a single component. This reduces the number of parts, lowers manufacturing costs and assembly complexity, while improving overall rigidity and reliability.

[0028] A drive assembly 6 is provided within the upper chamber 121. The drive assembly 6 includes a driver 61 and a drive shaft 62. In this embodiment, the driver 61 is a geared motor; in other embodiments, the driver 61 may be a stepper motor or a harmonic motor. The driver 61 is fixed to the top of the first plate 151 by a support rod, meaning the driver 61 is located within the upper chamber 121. The output shaft of the driver 61 is vertically downward. One end of the drive shaft 62 is coaxially and fixedly connected to the output shaft of the driver 61. The drive shaft 62 passes through the first plate 151 and is fixedly connected to the rotation center of the turntable 2, allowing the driver 61 to drive the turntable 2 to rotate. The drive shaft 62 is rotatably connected to the first plate 151 via a sealed bearing.

[0029] The bottom of the first plate 151 is provided with a cleaning component 7. In this embodiment, multiple sets of cleaning components 7 are provided. Preferably, the cleaning components 7 are distributed circumferentially along the path of the positioning station 21. Multiple sets of cleaning components 7 can clean the workpieces multiple times to improve the cleanliness of the workpieces.

[0030] like Figure 5 As shown, the cleaning assembly 7 includes a drive cylinder 71, a telescopic tube 72, and a spray head 73. The cylinder body of the drive cylinder 71 is fixed to the bottom of the first plate 151, and the piston rod of the drive cylinder 71 extends and retracts vertically downwards. The spray head 73 is fixed to the end of the piston rod of the drive cylinder 71. One end of the telescopic tube 72 is fixed to the first plate 151, and the other end is fixed to the spray head 73. In this embodiment, the telescopic tube 72 is a flexible pipe, and its corrugated structure can freely extend and compress with the extension and retraction of the piston rod. During operation, the piston rod of the drive cylinder 71 extends, accurately moving the spray head 73 to a position close to the workpiece to be cleaned, ensuring a good cleaning effect. When the turntable 2 transfers the workpiece, the piston rod of the drive cylinder 71 retracts, moving the spray head 73 away from the working area to avoid damage from collision with the workpiece.

[0031] The upper chamber 121 is provided with a first opening and closing assembly 8 and a second opening and closing assembly 9. The first opening and closing assembly 8 is used to control the opening and closing of the inlet 13, and the second opening and closing assembly 9 is used to control the opening and closing of the outlet 14. The first opening and closing assembly 8 includes a first cylinder 81 and a first limiting plate 82. The cylinder body of the first cylinder 81 is rotatably connected to the inside of the housing 1. Specifically, the first cylinder 81 is located in the upper chamber 121. In this embodiment, the first cylinder 81 is connected to the housing 1 by a pin to achieve left and right swinging. In other embodiments, the first cylinder 81 is connected to the housing 1 by a ball bearing. During the operation of the equipment, the first cylinder 81 can generate a small movement to counteract the lateral torque and stress generated by vibration, reducing the risk of damage to the connection between the first cylinder 81 and the housing 1.

[0032] The first plate 151 at the top of the inlet 13 has a first limiting groove. The first limiting plate 82 slides vertically within the first limiting groove and is fixedly connected to the piston rod of the first cylinder 81. The first cylinder 81 drives the first limiting plate 82 to descend and gradually close the inlet 13, or the first cylinder 81 drives the first limiting plate 82 to rise and gradually open the inlet 13.

[0033] The second opening and closing assembly 9 includes a second cylinder 91 and a second limiting plate 92. The cylinder body of the second cylinder 91 is rotatably connected to the housing 1. Specifically, the second cylinder 91 is located in the upper chamber 121. The second cylinder 91 can generate a slight oscillation with vibration to overcome the damage caused by vibration.

[0034] In this embodiment, the workpiece is transferred and cleaned in at least two ways: Method 1: Each positioning station 21 of the turntable 2 located in the workbench 4 section transfers a workpiece. The first cylinder 81 drives the first limiting plate 82 to rise, and the second cylinder 91 drives the second limiting plate 92 to rise. Both the inlet 13 and the outlet 14 are in the open state. The turntable 2 rotates 180°, sending the workpiece to be cleaned into the rinsing chamber 111 through the inlet 13, and transferring the rinsed workpiece from the outlet 14 to the workbench 4. Subsequently, the first limiting plate 82 and the second limiting plate 92 both descend to close the rinsing chamber 111. The cleaning components 7 in the rinsing chamber 111 simultaneously perform rinsing operations on each workpiece. Wastewater flows along the inclined direction of the third plate 153 into the wastewater chamber 112. Simultaneously, the operator or mechanical rod removes the cleaned workpiece from the workbench 4 and places the workpiece to be cleaned on the corresponding positioning station 21. After the workpieces in the rinsing chamber 111 have been cleaned, the first limiting plate 82 and the second limiting plate 92 rise, the inlet 13 and the outlet 14 open, and the turntable 2 rotates 180°, transferring the cleaned workpieces to the worktable 4, while simultaneously transferring the workpieces to be cleaned into the rinsing chamber 111. This process is repeated to achieve efficient batch cleaning of workpieces.

[0035] Method 2: The turntable 2 on the workbench 4 serves as a workpiece transfer station, where the operator places the workpiece to be cleaned near the inlet 13.

[0036] Subsequently, the first limiting plate 82 and the second limiting plate 92 rise, and the inlet 13 and outlet 14 open simultaneously. The turntable 2 rotates intermittently in coordination with the opening and closing of the inlet 13 and outlet 14 to transfer the workpieces on the worktable 4 near the inlet 13 into the rinsing chamber 111. That is, each time the inlet 13 and outlet 14 open and close, the turntable 2 rotates by the angle of one positioning station 21. The cleaning components 7 in the rinsing chamber 111 clean each workpiece multiple times.
