Description

Technical Field

[0001] The invention belongs to the technical field of precision special-shaped workpiece processing, and in particular relates to a purging device for special-shaped workpieces. Background Art

[0002] At present, there are no obstacles to effectively solve the cleaning of special-shaped parts. The difficulty lies in how to ensure effective blowing and drying after cleaning. After effectively cleaning the surface of such workpieces and the gap between jackets, how to ensure that no chemical reagents or water marks remain has become an increasingly important issue. In the early stage, most of the blowing was done manually, which was not only time-consuming and labor-intensive, but also could not guarantee that no water marks and chemical liquid residues would be left. In response to this problem, the present invention invented a method of fixed-point blowing and rotational moving blowing, which solved the human factor and achieved effective blowing and drying of special-shaped parts. The method is that the nozzle is directly facing the gap between the jackets and rotates 360 degrees. For blowing and drying, the outer contour is blown by fixed nozzles on both sides to ensure that each area can be evenly purged. This has been successful on the first device based on this patent and has been proven by a large amount of data. For this reason, we propose a blowing device for special-shaped parts.

[0025] The working principle and use process of the present invention are as follows: a batch of special-shaped workpieces are fixed on the rotating device of the rotating manipulator with a special fixture, and can be rotated and cleaned in the corresponding cleaning tank. After the corresponding cleaning process is completed, a group of nozzles fixed to the panel are used to effectively dry and blow the outside of the special-shaped parts, and the angle of the nozzle is adjustable. The bottom is driven by the blowing rotating mechanism to perform 360 rotational blowing along a certain radius. The rotating mechanism is fixed on a moving mechanism, and the movement of the mechanism realizes the blowing of a large number of special-shaped parts, and the purged chemical liquid falls on the leak receiving tray 7 at the bottom. The leak receiving tray 7 has a self-flushing function to reduce the splashing of the fallen chemical liquid on the outer contour of the special-shaped parts.

[0026] The X-axis left and right displacement is driven by the ball screw through the servo motor 1, and moves under the guidance of the linear guide mechanism; the Y-axis is connected by fixing the associated parts of the ball screw, and the up and down movement mechanism is the same as the X-axis; the R-axis rotation mechanism is fixed to the Y-axis through the connecting plate, and the motor rotates through the belt drive to drive the lower end gear to rotate the R-axis rotation mechanism on the manipulator. The servo motor 1 drives the flower basket through the belt drive and the flower basket gear drive, thereby driving the flower basket to rotate. The Y-axis of the manipulator can shake up and down, thereby driving the rotation mechanism to shake; when the manipulator mechanism moves to the purge platform, the manipulator rotation mechanism rotates to a certain angle, and the nitrogen nozzles on both sides and the bottom of the panel start to purge. After the purge is completed, the manipulator moves to the next process tank

[0027] At present, there are mainly two methods for cleaning and purging the jacket of special-shaped parts: 1. Manual cleaning and purging, manually placing the special-shaped parts in chemical liquid for cleaning, and manually purging with a nitrogen gun after cleaning; 2. Using an automatic manipulator to grab the flower basket where the special-shaped parts are placed, and clean them in the work station slot without placing the basket. After cleaning, a fixed purge nozzle is used to position and purge a certain position on the surface of the special-shaped parts. After the positioning purge is completed, the bottom rotating cylinder 51 starts to purge the gap of the jacket.

[0028] The first method can be used in any special-shaped parts processing process, such as using hydrochloric acid and deionized water to remove metal pollution particles on the surface, but manual cleaning is prone to artificial pollution, and manual blowing may result in leakage, incomplete blowing, or impurities introduced during the blowing process, resulting in unqualified quality inspections and returning to the process treatment stage, wasting workers' time, and the cleaning efficiency is not high; the second method requires ordering a fully automatic device to locate the blowing process, and the flower basket is driven to rotate by the rotation of the manipulator. The key blowing area facing the panel positioning fixed nozzle can be blown clean to meet the high finish requirements of the process; after the outer contour is blown, the manipulator rotation mechanism stops at a certain angle, and the bottom rotating cylinder 51 fixed plate is facing the gap of the special-shaped part jacket to ensure that each area can meet the process requirements.

[0029] The device uses servo motor 1 because it has strong overload resistance and is particularly suitable for occasions with instantaneous load fluctuations and quick start requirements. It also runs smoothly at low speeds and does not produce stepping operations similar to stepper motors. For workpieces with fixed spacing in the basket, accurate position control is very important, and servo motor 1 realizes closed-loop control of position, speed and torque.

[0030] The drive shaft of the servo motor 1 is connected to the coupling 3, and the other end is connected to the ball screw. The motor drive seat and the screw support seat are limited by hardware. The nut seat is connected to the ball screw through four threaded holes on the side, and the four threaded holes on the top of the nut seat are connected to the purge connecting plate 5.

[0031] Four ribs 53 are welded to the end of the bottom purge rotating cylinder 51 fixing plate, and a circle with a radius slightly larger than that of the rotating cylinder 51 connecting plate is opened on the top to ensure that the rotation of the cylinder is not affected and the chemical liquid dripping from the purge does not directly drip onto the rotating cylinder 51. A vertical isolation plate is fixed to the left side of the servo motor 1 fixing plate, and a groove is opened in the middle of the isolation plate to allow the cylinder fixing plate to pass through and slide. The isolation plate isolates the chemical liquid splashed by the purge so that it will not splash directly onto the linear guide or ball screw. The nitrogen pipeline required for purge moves back and forth through the inside of the tank chain 6. When the purge is completed, the leak tray cover is closed, and DI water enters from an inlet to clean the leak tray.

[0032] When the robot lifts the flower basket, it moves to the workstation slot for rotation and shaking process cleaning. After the cleaning is completed, the rotation and shaking stops, and the robot moves to the purge platform station. At this time, the special-shaped cylindrical surface inside the flower basket is covered with cleaning chemical liquid. The robot drives the flower basket down to a suitable position, the rotating mechanism starts to rotate, and the nitrogen nozzle starts to purge. In order to ensure sufficient nitrogen gas volume, the nitrogen nozzles fixed on the panel are grouped in pairs for rotational purge. After the outer contour is purged, the robot's rotating mechanism stops at a certain angle, and the bottom rotating cylinder 51 fixed plate is facing the gap of the special-shaped jacket to purge, ensuring that each area can meet the process requirements. After the purge is completed, the robot drives the flower basket to move to the next station.

[0033] Practice has proved that the method and device of the present invention solve the problem of residual chemical liquid after purging of special-shaped cylindrical parts, greatly improve the cleanliness of the surface of various special-shaped parts, effectively increase the output of the special-shaped cylindrical cleaning process, reduce production costs, and it is a simple and easy-to-promote device and method. This method and device can also be used in equipment for wet processing processes such as electronic components and special workpieces.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
