Description

[0001] Field of technology to which the invention relates

[0002] The invention relates to equipment for cleaning parts from process oils and contaminants during their production process.

[0003] Technology Level

[0004] There are various types of cleaning lines, consisting of baths in which all parts cleaning operations: jet rinsing and washing, ultrasonic cleaning, drying with air flows, are carried out in the cavity of the baths, where they are delivered by a lifting and transport mechanism-manipulator.

[0005] The closest to the proposed technical solution is a three-position automatic ultrasonic line for intensifying the cleaning process of aircraft turbine blades by superimposing ultrasonic vibrations, followed by rinsing and drying of the parts with a flow (https: / / sp-sonic.ru / product / ultrazvukovye-linii / 3-kh-pozitsionnaya-avtomaticheskaya-ultrazvukovaya liniya / ?ysclid=mgdmksi9q8823931520#desc). The line is an integrated device of cleaning equipment with a system for moving loading baskets, loading and unloading tables. During one cycle, the moving system simultaneously grips the baskets, lifts them, moves them between positions, and lowers them into the baths where they are cleaned. The cycle is then repeated.

[0006] A drawback of the line is the complex design of the handling system, which consists of a bulky frame gantry supported by guides mounted on the main frame with longitudinal reciprocating motion. It also carries mechanisms for lifting and lowering baskets with parts into the processing baths. The complex basket movement trajectory and the large number of idle strokes increase cycle times and reduce productivity.

[0007] The task is to simplify the design, reduce the weight and the number of elementary movements of moving parts.

[0008] Disclosure of the essence of the invention

[0009] The invention consists of a simplified trajectory for cassettes containing parts moving between stations. Movement occurs along horizontal guides using a pusher. The cassettes have a mesh bottom. Parts are placed in the cassettes in a single layer. At the ultrasonic cleaning station, the cassette, along with a section of the guides and emitters mounted above the cassette, can be immersed in a single movement into a bath of cleaning solution, where ultrasonic treatment occurs. At other stations, blasting occurs directly where the cassettes are positioned on the guides. Treatment is carried out using jets of liquid (air) emanating from nozzles (nozzles) located above the cassette, either fixed or rotatable around a vertical axis. The process is carried out with the enclosure hood lowered. A tray for collecting waste liquid is located below the cassette.After the cycle is completed, the casing rises up and frees the passage of cassettes when moving between positions.

[0010] The technical result is a simplified design while simultaneously optimizing the trajectory of the cassettes containing the parts. The moving portal with lifting mechanisms has been completely eliminated from the system. The number of elementary movements in the device as a whole has been reduced, thereby saving time on idle movements.

[0011] Brief description of drawings

[0012] Fig. 1 shows a diagram of the first embodiment of the ultrasonic cleaning line.

[0013] Fig. 2 shows a diagram of the second embodiment of the ultrasonic cleaning line.

[0014] The basic component of the line is frame 1, on which the following technological process positions are located sequentially (shown in Roman numerals):

[0015] - position I - position for loading cassettes with parts onto the line;

[0016] - position II - pre-wash position;

[0017] - position III - ultrasonic cleaning position;

[0018] - position IV - rinsing position;

[0019] - position V - drying position;

[0020] - position VI - position for unloading cassettes with parts from the line

[0021] Implementation of the invention

[0022] Longitudinal guides 2 are attached to the frame, on which cassettes 3 are positioned at all positions. The cassettes have a mesh bottom on which the parts are laid in a single layer. A manipulator 4 is also mounted on the frame, capable of performing reciprocating longitudinal movements under the action of a cylinder 5.

[0023] Positions II and IV are equipped with jet cleaning modules 6, mounted on the frame above the cassettes. Position V is equipped with a blower module 7, mounted on the frame above the cassette. Jet cleaning modules 6 and 7, with attached nozzles, can be installed either fixedly or with the ability to rotate around a vertical axis. In addition, positions II, IV, and V are each equipped with a guard housing 8, mounted on a movable panel 9 of a scissor lift 10, mounted on the frame above the cassettes. Trays 11 are installed on the frame beneath the cassettes.

[0024] Position III is arranged as follows. A scissor lift 12 is mounted on a frame above the cassette, and a unit 14 of ultrasonic emitters 15 is attached to its movable panel 13.

[0025] In the first variant, at position III, section 16 of the guide is separately secured to the movable panel 17 of the scissor lift 18 installed in the cavity of the bath.

[0026] In the second variant, at position III, section 16 of the guide is separately secured to panel 19, rigidly connected to block 14 of ultrasonic emitters.

[0027] The ultrasonic cleaning line works as follows.

[0028] Cassettes 3 with parts are fed to position I at a frequency corresponding to the line's operating cycle. Parts are processed at all positions simultaneously. During processing at positions II, IV, and V, the guard covers 8 are lowered, and pre-washing, rinsing, and drying, respectively, are performed using liquid (gas) jets emanating from nozzles. At the same time, at position III, the cassettes with parts and the unit 14 with ultrasonic emitters 15 are lowered into a bath with a cleaning solution, and ultrasonic cleaning of the parts is carried out. Upon completion of the required processing cycle time, all devices mounted on the scissor lifts are simultaneously raised to their initial positions: the guard covers 8, the emitter unit 14, and the cassette from the bath. Manipulator 4 then simultaneously advances all cassettes one step. The cycle is repeated. Thus, the cassettes with parts sequentially undergo all necessary processing stages.
