For example, when the workpiece needs to be turned over twice to achieve posture adjustment, the handling device 6 grabs the workpiece and flips it over, then places it on the flipping positioning device 7, and then moves the clamp of the handling device 6 The claw 61 resets and grabs the workpiece again, and then performs a second flip to adjust the attitude of the workpiece.

The support and positioning station 71 can position the workpiece to prevent the workpiece from tipping over or moving in position during the second flipping process, causing the clamping jaw 61 to be unable to grasp it.

The second tank 72 is used to collect residual cleaning liquid flowing out from the workpiece.

Further, the handling device 6 includes a robot and a clamping claw 61. The clamping claw 61 is provided at the working end of the robot. The robot is a four-axis robot, a five-axis robot, or a six-axis robot.

Optionally, a six-axis robot is used in the embodiment of the present invention, which is effectively compatible with the automatic loading and unloading of various types of hydraulic valve bodies, meets the requirements for automated mass production, and can also be effectively connected to automated conveying production lines or other automated logistics delivery forms.

In some embodiments, the cleaning system also includes a control system, which is used to control the actions of the cleaning device and the handling device 6 . For example, the control system adopts PLC control to realize the automation of workpiece grabbing, workpiece cleaning and other tasks, and realize the automated operation of the cleaning system.

The hydraulic valve body used in the electro-hydraulic control system of the hydraulic support has a complex hole system and many deep intersecting holes. It is easy to produce burrs and flash edges during processing. Cleaning before product assembly has always been a key factor that troubles the quality stability of the product.

According to the multi-point valve body cleaning method of the embodiment of the present invention, any one of the above cleaning systems is used to clean the valve body, wherein the valve body is the above-mentioned hydraulic valve body, and the parts to be cleaned are the parts on each side of the hydraulic valve body. hole, specifically including the following steps:

S101. Place the valve body in the initial posture in the cleaning device and clamp the valve body. At this time, part of the parts to be cleaned on the valve body can be cleaned in this initial posture.

S102. Start the pumping component and control some nozzles to spray the cleaning liquid so that the parts to be cleaned on the valve body in this posture can be cleaned in the moving path of the support platform. That is to say, by moving the support platform, the workpiece can be moved to a position corresponding to the corresponding nozzle, and then the cleaning liquid ejected from the nozzle can be used to clean the corresponding hole position.

S103. Determine the single movement distance of the support table and the single stop time of the support table, and control the movement of the support table until the cleaning of the parts to be cleaned on the valve body in this posture is completed. According to the layout position of the nozzle, the position of the hole on the valve body, and the position of the support table, the single moving distance and single stop time of the support table are determined. The control system controls the movement of the support table. After the movement is in place, the nozzle is cleaned. The corresponding time of the area to be cleaned is the rest time.

S104. Close the pumping component, adjust the valve body to the next posture, place the valve body in the cleaning device, clamp the valve body, and repeat steps S102 and S103. Since there are holes to be cleaned on different sides of the hydraulic valve body, one clamping cannot clean the holes on all sides. It is necessary to change the posture of the valve body to ensure that all parts to be cleaned are cleaned.

S105. Determine whether the cleaning of all parts to be cleaned in the valve body is completed. If so, take out the valve body; if not, repeat step S104 until the cleaning of the valve body is completed. Different valve body models may require a third posture adjustment, or a re-cleaning may be required after the cleaning is completed to ensure the quality and effect of cleaning. Therefore, it is necessary to determine whether the valve body needs to be cleaned again. Judgment to determine whether the cleaning of the valve body is complete.

The following is a detailed description of the working principle of the embodiment of the present invention in conjunction with the specific structures shown in Figures 1 to 9:

The valve body is transported to the picking position of the six-axis robot (i.e., the transport device 6 in the above embodiment). The six-axis robot moves and the valve body is clamped by the valve body clamp. After the automatic door of the cleaning device is opened, the six-axis robot moves the valve body. The body is moved and placed on the valve body loading and unloading platform (ie, the clamping assembly 2 in the above embodiment). After the valve body is placed in place, the six-axis robot returns to its original position. The automatic door of the cleaning device is closed, the valve body clamping cylinder (i.e., the second driver 23 in the above embodiment) moves to complete the clamping of the valve body, and then the single-axis drive assembly (i.e., the third driver in the above embodiment) drives The valve body loading and unloading platform moves. At this time, the protective baffle driving cylinder (i.e., the fourth driver 124 in the above embodiment) drives the baffle and telescopic shield (organ cover 123) on the feed port to move the valve body to the top of the loading and unloading platform. and side shielding. After the cleaning hole on the leftmost side of the valve body reaches the position of the high-pressure nozzle on the rear end face (i.e., the second nozzle unit 32 in the above embodiment), the electro-hydraulic control valve opens the corresponding passage, and the high-pressure water jet sprays out to complete the corresponding hole. position is cleaned, and then the single-axis drive assembly is fed a certain distance in sequence to complete the cleaning of all holes on the rear end face. Then the single-axis drive assembly drives the valve body loading and unloading platform to move in the direction of exiting to the initial position, and then according to the above-mentioned rear end face cleaning steps, the upper end face high-pressure nozzle (ie, the third nozzle unit 33 in the above embodiment) and the front end face high-pressure nozzle are used The nozzle (i.e., the fourth nozzle unit 34 in the above embodiment) sequentially completes the cleaning of all the holes on the upper end surface and the front end surface shown in Figure 3. After the cleaning of the above three surfaces is completed, the valve body loading and unloading platform moves to the left Move sideways to the position of the left end high-pressure nozzle (i.e., the first nozzle unit 31 in the above embodiment), and the electro-hydraulic control valve opens the passage corresponding to the left end high-pressure nozzle to complete the cleaning of the left end hole of the valve body. After completing the cleaning of all the holes on the above four surfaces, the single-axis drive assembly drives the valve body loading and unloading platform to return to the original position. During the exit process, the three air knives corresponding to the upper end face, front and rear end faces are opened to dry the valve body surface. After the loading and unloading platform returns to its original position, the protective baffle drives the cylinder to drive the upper baffle and telescopic shield (organ cover) of the feed port back to its original position. Then the automatic door of the cleaning device opens, and the six-axis robot drives the valve body clamping claw to grab the valve body. Exit the high-pressure fixed-point cleaning mechanism and transport it to the top of the valve body flip positioning device. Flip the valve body 90 degrees and place it on the valve body positioning support frame (i.e., the support positioning station 71 in the above embodiment). The valve body clamping jaws are opened. Open, release the valve body, and then the six-axis robot drives the valve body clamping claw to flip 90 degrees again for grabbing. Finally, the valve body is flipped 180 degrees for grabbing, and then the valve body is placed on the valve body loading and unloading platform. Wait for the valve body to be grasped. After the body is placed in place, the six-axis robot returns to its original position.

The automatic door of the cleaning device closes, and the valve body clamping cylinder moves to complete the clamping of the valve body. Then the single-axis drive component drives the valve body loading and unloading platform to slide and move. At this time, the protective baffle drives the cylinder to drive the upper baffle and telescopic of the feed port. The protective cover (organ cover) covers the top and sides of the valve body loading and unloading platform. Utilize the lower end face high-pressure nozzle (i.e., the fifth nozzle unit 35 in the above embodiment) and the left end face high-pressure nozzle (i.e., the first nozzle unit 31 in the above embodiment) to complete the lower end face of the valve body in its initial posture (this face at this time Clean the holes on the right end surface (facing upward) and the right end surface (this surface is facing left at this time).

After all six sides of the valve body have been cleaned, the single-axis drive assembly drives the valve body loading and unloading platform back to its original position. During the exit process, the air knife is turned on to dry the valve body surface, and the valve body loading and unloading platform returns to its original position and is protected. The baffle driving cylinder drives the baffle and telescopic guard (organ cover) on the inlet of the cleaning chamber back to their original positions. Then the automatic door of the cleaning device opens, and the six-axis robot drives the valve body gripper to grab the valve body and place it on the valve body. At the unloading position, high-pressure fixed-point cleaning of the six face positions of the valve body is automatically completed.

The cleaning chamber (i.e., the chamber of the guard 12 in the above embodiment) is suspended as a whole and installed above the recovery water tank (i.e., the first box 13 in the above embodiment). During the high-pressure water jet cleaning process, the water spray that occurs Splashes flow into the recovery water tank from the bottom of the cleaning chamber due to the shielding of the cleaning chamber guard, the upper baffle of the cleaning chamber inlet and the telescopic guard (organ cover). The water flows from the first chamber to the second chamber through the filter screen, and is then pumped by the water pump and enters the high-pressure pump system (i.e., the pumping assembly 4 in the above embodiment) through the water inlet pipe. It is filtered twice by the high-pressure pump system and then pressurized through the water outlet pipe. Connected to the electro-hydraulic reversing valve, the electro-hydraulic reversing valve then branches out sub-pipes and is injected through each high-pressure nozzle and then flows into the recovery water tank, realizing repeated recycling of water and reducing the waste of water resources.

The water in the high-pressure pump system flows in through the water inlet pipe and passes through the filter. After filtering, it is pressurized to a certain extent by the water inlet booster pump and then enters the high-pressure plunger pump. The high-pressure plunger pump increases the water pressure to the operating pressure and is then connected to the water outlet pipe. Connect the reversing valve and nozzle.

In the embodiment of the present invention, multi-point high-pressure fixed-point cleaning of the hydraulic valve body is realized, which improves the cleanliness of the hydraulic valve body. Compared with the ultrasonic cleaning method, it effectively reduces the burrs and intersection flying objects with high bonding strength of the valve body. On the other hand, compared with the manual hand-held high-pressure water gun cleaning method, the cleaning quality and efficiency are improved, human labor intensity is greatly reduced, cleaning flexibility is improved, and the requirements of automated mass production are met. At the same time, the reuse of water also reduces energy and water consumption. Waste of resources.
