Detailed Description

The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

Examples, see fig. 1-6: the cleaning equipment comprises a frame 10, a clamp assembly 60 for installing a corresponding workpiece 40, at least one cleaning device 20 which is slidably assembled on the frame 10, a rotating assembly 50 which is installed on the frame 10, and a gas-liquid circulation pipeline system 30, wherein the clamp assembly 60 is assembled on the rotating assembly 50. The cleaning device 20 can slide back and forth in the direction of the jig assembly 60, and the gas-liquid circulation pipeline system 30 is connected to the cleaning device 20 and outputs gas and cleaning liquid to the cleaning device 20. Wherein the cleaning device 20 slides along the frame 10 to approach the jig assembly 60 and sprays a cleaning liquid to the workpiece 40 to clean the workpiece 40 mounted on the jig assembly 60. The rotating assembly 50 drives the clamp assembly 60 to rotate after the cleaning device 20 slides away from the clamp assembly 60, so that the cleaning solution attached to the workpiece 40 is centrifugally removed. The cleaning device 20 is slid along the frame 10 to be adjacent to the jig assembly 60 and sprays gas toward the workpiece 40 to dry the workpiece 40 mounted to the jig assembly 60.

The gas-liquid circulation pipeline system 30 can output gas and cleaning liquid with corresponding pressure to the direction of the cleaning device 20, so that the cleaning device 20 can output gas and/or cleaning liquid with corresponding pressure according to a corresponding preset program. The cleaning apparatus 20 first sprays a cleaning liquid, which may be pure water or a solvent mixed with an additive, onto the workpiece 40 clamped by the clamp unit 60. The cutting fluid and chips on the surface of the workpiece 40 flow with the cleaning fluid under the washing of the cleaning fluid, and the primary cleaning is completed.

After the workpiece 40 is primarily cleaned, a cleaning residual cleaning solution remains on the surface of the workpiece 40. The rotating assembly 50 rotates under the control of a built-in program and drives the clamp assembly 60 to rotate at a high speed, and the workpiece 40 rotates along with the clamp assembly 60, so that the cleaning liquid attached to the surface of the workpiece 40 is thrown out under the action of centrifugal force, and the cleaning liquid residue on the surface of the workpiece 40 is reduced or eliminated.

When the rotation of the rotating member 50 is stopped, the clamp member 60 is stopped at a predetermined angle, and a cleaning liquid film, such as a water film, which is not thrown off by the centrifugal force, remains on a part of the processing surface of the workpiece 40. The cleaning device 20 blows the gas with the preset pressure to the processing part of the workpiece 40 again under the control of the built-in program to blow dry the cleaning liquid film on the surface of the workpiece 40, so that the cleaning effect on the surface of the workpiece 40 is good, and the stains are less. The cleaning equipment disclosed by the application integrates related functions of cleaning, spin-drying, blow-drying and the like, integrates multiple processes into the same equipment, is miniaturized, reduces circulation and clamping processes of the whole production link, enables the workpiece 40 to meet the requirement of finished products after clamping once, meets the requirement of cleanliness of customers, and avoids pollution and collision in the circulation process.

See fig. 1-3 for: in this embodiment, the cleaning device 20 includes a sliding driving member 24 mounted on the frame 10, a sliding bracket 23 slidably mounted on the frame 10, an air spraying unit 22 and a liquid spraying unit 21 mounted on the sliding bracket 23, and the sliding driving member 24 is slidably connected to the sliding bracket 23 to move the air spraying unit 22 and the liquid spraying unit 21 away from or close to the clamping unit 60. The liquid spraying unit 21 is used for spraying a cleaning liquid, and the gas spraying unit 22 is used for spraying a gas. Alternatively, the sliding bracket 23 is configured to have an approximately "T" or "L" shape, so that the air injection assembly 22 and the liquid injection assembly 21 extend into the frame 10 and are parallel to the cleaning direction of the workpiece 40.

The slide driving member 24 slides the slide frame 23 along the predetermined track of the frame 10 so that the air injection unit 22 and the liquid injection unit 21 can slide toward the corresponding tracks to approach or separate from the workpiece 40. For example, the slide driving member 24 drives the slide bracket 23 to linearly reciprocate along a guide rail on the frame 10, wherein the slide driving member 24 may be a linear expansion and contraction mechanism such as an air cylinder or a hydraulic cylinder, or a linear reciprocating structure such as a cam mechanism, a rack and pinion mechanism, or a link mechanism, to drive the slide bracket 23 to linearly reciprocate. Alternatively, the sliding driving member 24 drives the sliding bracket 23 to slide back and forth along the guide rail on the frame 10, wherein the sliding driving member 24 may be configured as a connecting rod structure, a crank mechanism, or the like.

The spray assembly 21 communicates with the gas-liquid circulation piping system 30 to control the gas-liquid circulation piping system 30 to output a cleaning liquid to spray the cleaning liquid toward a predetermined position of the workpiece 40 according to a built-in program, so that the cleaning liquid washes the cutting liquid and chips adhering to the surface of the workpiece 40. The gas injection assembly 22 is communicated with the gas-liquid circulation pipeline system 30, and controls the gas-liquid circulation pipeline system 30 to output gas to inject the gas towards a preset position of the workpiece 40 according to a built-in program, so that the gas can blow and dry the cleaning liquid attached to the surface of the workpiece 40.

Optionally, the cleaning devices 20 are provided with three groups and distributed at intervals, and the three groups of the cleaning devices 20 respectively slide along the rack 10 to clean different parts of the workpiece 40. Each set of cleaning devices 20 corresponds to one of the processing chambers 41 so that the cleaning apparatus can clean different processing locations of the workpiece 40 at the same time.

It should be noted that, when the cleaning device 20 sprays gas or cleaning liquid onto the workpiece 40, the slide driving member 24 can drive the slide support 23 to move linearly and stay at a preset position, so that the liquid spraying assembly 21 sprays the cleaning liquid onto the workpiece 40, or the gas spraying assembly 22 sprays gas onto the workpiece 40, so as to form a static spraying cleaning effect. Alternatively, the slide driving member 24 may drive the slide carriage 23 to reciprocate linearly so that the spray unit 21 repeatedly moves along the processing chamber 41 of the workpiece 40 and sprays the cleaning liquid onto the workpiece 40 during the movement of the slide carriage 23, or the spray unit 22 repeatedly moves along the processing chamber 41 of the workpiece 40 and sprays the gas onto the workpiece 40 during the movement of the slide carriage 23, thereby forming a movable spray cleaning effect.

Namely, the slide table 11 can realize a wide range of movement of the jig assembly 60, and the range of movement is wide. The sliding table 11 can drive the clamp assembly 60 to move to the movable range of the cleaning device 20, so that the movement amount of the cleaning device 20 is reduced, and the compactness of the whole structure and the stability of the liquid supply and air supply of the cleaning device 20 are improved.
