Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cleaning device, and more specifically, to cleaning an object in or on a cleaning tank of an ultrasonic cleaning device used in a cleaning process in the manufacture of electronic equipment, etc. This invention relates to a washing device that is made to swing.

Conventional technology Conventionally, ultrasonic cleaning equipment has been used in the cleaning process in the manufacturing of electronic devices, etc., and the object to be cleaned is immersed in a cleaning tank filled with an organic solvent of this equipment, and debris is removed from the surface of the object to be cleaned. In order to remove chips and chips evenly, it was necessary to swing it up and down.
In addition, usually multiple cleaning tanks are filled with several types of organic solvents, and since it is undesirable if these solvents mix with each other, the objects to be cleaned that are transferred between the cleaning tanks are The organic solvent was drained by swinging it up and down.

Problems to be Solved by the Invention Incidentally, as described above, the swinging in the cleaning process is performed while the object to be cleaned is immersed in the cleaning tank and while the object is pulled up from the cleaning tank. However, if these oscillations are not performed properly, the former will cause problems such as a decline in quality due to uneven cleaning of the object to be cleaned, and the latter will cause problems such as poor quality due to the mixing of several types of solvents. If the cleaning power deteriorates or if the items to be cleaned are removed from the ultrasonic cleaning apparatus with solvent still attached to them, problems may occur, such as an adverse effect on the human body handling the items. Therefore, there has been a demand for the development of a device that properly rocks the object to be cleaned, but at present no automated cleaning device that achieves proper rocking has been provided.

Means for Solving the Problems The present invention provides a device for placing objects to be cleaned that is supported vertically movably via rods on the side wall of an outer frame that surrounds the upper portions of a series of multiple cleaning tanks arranged side by side. a first cam drive mechanism for vertically swinging the object to be cleaned supported by the bracket via the rod in the cleaning tank or at the upper part of the outside of the cleaning tank to perform cleaning or draining the cleaning liquid; To provide a cleaning device equipped with a second cam drive mechanism that moves the object to be cleaned supported by the bracket via the first cam drive mechanism to a position inside the cleaning tank and an upper part outside the cleaning tank. This solves the above problems.

Function: In the present invention, the second cam drive mechanism immerses the object to be cleaned into the cleaning tank or lifts it to the upper part of the outside of the cleaning tank, and the first cam drive mechanism immerses the object to be cleaned into the cleaning tank and lifts the object to the outside of the cleaning tank. Inside the cleaning tank, it is swung vertically for cleaning, and at the top outside of the rinsing tank, it is swung vertically for draining the cleaning liquid.

Embodiment An embodiment of the rocking device according to the present invention will be described with reference to FIGS. 1 and 2. In the same figure,
Reference numerals 1, 1, . . . denote a plurality of cleaning tanks arranged side by side in series, and each tank is filled with the same or different types of organic solvents. Reference numeral 2 denotes an outer frame body surrounding the upper portions of the cleaning tanks 1, 1, . . . to prevent the vaporized organic solvent from leaking into other spaces.

3, 3... are a pair of rods that are vertically movably installed via support members 4, 4... at locations corresponding to the respective cleaning tanks 1, 1... on the side wall portion 2a of the outer frame body 2. , 5, 5... are plates that connect the lower ends of the pair of rods 3, 3..., and 6, 6... are plates whose upper ends are attached to the rods 3, 3..., and whose lower ends are attached to the objects to be cleaned. Reference numeral 7 is a bracket on which it is placed, and reference numeral 8 is a cam drive mechanism that swings the brackets 6, 6, etc. by vertically moving the rods 3, 3... with a constant stroke. It is composed of a two-stage type with two cam drive mechanisms 10. The first cam drive mechanism 9 includes the outer frame 2
A first pillow block 9a is provided below the side wall portion 2a of the
a first horizontal shaft 9b rotatably supported horizontally via 9a; a first disk-shaped cam plate 9c eccentrically attached to the horizontal shaft 9b at a constant pitch;
First cam followers 9d, 9d are attached to the lower surfaces of the plates 5, 5... connecting the rods 3, 3, and are in contact with the peripheral end surface of the first cam plate 9c.
..., a first drive source 9e that rotates the first horizontal shaft 9b, and, for example, a chain 9f that is wrapped between the drive source 9e and the horizontal shaft 9b. Further, the second cam drive mechanism 10 is
A second horizontal shaft 10b is rotatably supported horizontally below the first cam drive mechanism 9 via second pillow blocks 10a, 10a, and is attached eccentrically to the horizontal shaft 10b at a fixed pitch. and a second cam follower 10d that is attached to the lower surface of the first pillow block 9a, 9a... and abuts the peripheral end surface of the second cam plate 10c. , 10d... and a second drive source 10 that rotates the second horizontal shaft 10.
e, and, for example, a chain 10f that is wrapped between the drive source 10e and the horizontal shaft 10b.

In the first cam drive mechanism 9 of the rocking device 11 configured as described above, if the distances from the rotation center to the peripheral end surface of the eccentric cam plate 9c are a and b (however, a>b), then the horizontal axis 9b By rotating the vertically installed rods 3, 3, the maximum stroke A (=a-
By moving up and down in b), the object to be cleaned 7 placed on the bracket 6 can be swung with a constant stroke. Next, in the second cam drive mechanism 10, if the distances from the rotation center to the peripheral end surface of the eccentric cam plate 10c are c and d (however, c>d),
By rotating the horizontal axis, the first drive mechanism 9 and the vertically installed rods 3, 3 move up and down with the maximum stroke B (=c-d), and the object to be cleaned 7 placed on the bracket 6 is moved. It can be oscillated with a constant stroke. In this embodiment, the first cam drive mechanism 9 realizes a small stroke swing of the object to be cleaned 7 in or on the cleaning tank 1, and
With the cam drive mechanism 10, it is possible to swing the object 7 to be cleaned with a large stroke in or on the cleaning tank 1 and to lift the object 7 from inside the cleaning tank 1 onto the cleaning tank 1. There is.

As described above, the first and second drive mechanisms 9, 1
0 are combined to realize several types of rocking motions, thereby making it possible to properly rock the object 7 to be cleaned.

Effects of the invention According to the invention, the second cam drive mechanism immerses the object to be cleaned in the cleaning tank and lifts it to the outside upper part of the cleaning tank, and the first cam drive mechanism immerses the object to be cleaned into the cleaning tank and lifts the object to the outside upper part of the cleaning tank. It is possible to automatically and reliably swing the object to be washed up and down in the washing tank for washing, and also to swing the object up and down in the upper part outside the washing tank to drain the washing liquid. Moreover, since all of the above operations are performed by a cam drive mechanism, the work from immersion cleaning of the object to be cleaned to draining and removal of the liquid can be performed in an orderly manner and at high speed. The swing conditions for draining the liquid can be easily set by changing the cam shape and rotation speed. Therefore, it goes without saying that the occurrence of uneven cleaning can be prevented, and in particular,
The first cam drive mechanism can be used to quickly drain the liquid after cleaning, so a simple mechanism prevents deterioration of cleaning power due to mixing of different types of cleaning liquids, and also prevents the operator from using cleaning liquids. The negative impact on the environment can also be reduced. Further, the outer frame prevents the cleaning liquid from scattering during draining.
