Description

[Detailed Description of the Invention] <Technical Classification/Field> The disclosed technology belongs to a technical field in which objects to be cleaned, such as lenses, are oscillatedly cleaned in a cleaning tank provided in an automatic cleaning device.

<Explanation of the gist> This invention, in a cleaning process that is a transition from a polishing process, uses a cleaning basket loaded with lenses, etc. as objects to be cleaned, in a plurality of cleaning tanks installed adjacent to each other in an automatic cleaning device. This invention relates to a device that swings for cleaning by being placed on a pedestal attached to a support arm installed under a lifting frame facing the sky, etc.
An elevating drive device and a swing drive device, both fixed to the frame of the automatic cleaning device, are linked together via a swing link, and a pin is pivotally supported in the middle of the swing link via a fulcrum adjustment body. The lifting frame is moved up and down by the rotation of the lifting drive device via a link bar connecting the lifting frame and one end of the swinging link on the lifting drive device side;
The swinging drive device immerses the object to be cleaned in the cleaning liquid of each washing tank when the lifting frame is lowered, and at the same time, the swinging body is linked to the other end of the swinging link so as to be relatively slidable. This invention relates to a washing swinging device for an automatic washing apparatus, which swings the swinging link in the vertical direction by rotation, and washes the object to be washed while swinging it in the washing liquid.

<Prior art> As is well known, lenses and the like are usually cleaned after the polishing process, and the automatic cleaning equipment that cleans the cleaning items is sequentially placed in a plurality of cleaning tanks installed adjacent to each other. It has a cross-feeding device that conveys the objects to be cleaned, and a lifting device that moves the objects conveyed onto each washing tank up and down in each washing tank for cleaning. They are linked to perform sequential cleaning and advance conveyance.

In the conventional automatic cleaning device, the lifting device has a lift air cylinder that lifts and lowers a pedestal on which the objects to be cleaned are placed and washed, which are sequentially conveyed through the lateral transport device, and an air cylinder for lifting and lowering, and an air cylinder for lifting and lowering the pedestal on which the objects to be cleaned are placed and washed. It has a cleaning air cylinder that cleans the placed pedestal by moving it up and down in the cleaning liquid of each cleaning tank. Therefore, the power source for driving the cleaning and the power source for driving the set are separate. Since it is provided separately, the automatic cleaning mechanism becomes complicated and the device becomes large.

In addition, since each air cylinder is used as the power source for driving, the impact when the piston rod of each air cylinder stops at the end of its stroke causes the objects to be cleaned placed on the above-mentioned pedestal to move against each other. There is a problem in that the object to be cleaned is easily damaged due to interference such as collision with the object or strong contact with the pedestal.

OBJECT OF THE INVENTION The purpose of the present invention is to solve the technical problem of the cleaning mechanism of an automatic cleaning device based on the above-mentioned prior art, and to provide an automatic cleaning device with both a lifting drive function and a swinging drive function. A series of operations changes the lifting/lowering and swinging of the pedestal, allowing the object to be cleaned placed on the pedestal to be smoothly raised/lowered, transported and oscillated for cleaning, benefiting finishing applications in the precision industry. It is an object of the present invention to provide an excellent washing rocking device for automatic washing equipment.

<Structure of the Invention> In order to solve the above-mentioned problems, the structure of the present invention, which is in accordance with the above-mentioned object and whose gist is the scope of the above-mentioned claims, is to solve the above-mentioned problems by cleaning lenses, etc. that have been conveyed to an automatic cleaning device by a conveyor on the feeding side, etc. The objects to be cleaned are sequentially transferred via a cross-feeding device to a pedestal with a support arm attached to a lifting frame above each cleaning tank, and are then fixed to the frame of the automatic cleaning device and shaken. By rotating the elevating motor of the elevating drive device, which is linked via the movable link, by a predetermined rotation, the fulcrum of the swinging link is lowered by its eccentric pin, and the elevating frame and the base end of the swinging link are connected together. The above-mentioned pedestal is lowered and inserted into the cleaning liquid of each washing tank through the downward movement of the link bar, and then the lifting motor is stopped and the swinging motor of the swinging drive device is rotated. Then, the eccentric pin shaft of the swing motor swings the swing link up and down about the fulcrum, and swings the object to be cleaned on the pedestal in the washing tank via the link bar. After washing, the elevating drive device is reversely rotated again to raise the pedestal to the lateral feeding device, and the lateral feeding device moves the object to be cleaned on the pedestal to the pedestal in the next cleaning tank. It is a technical measure that allows the transfer of
