Description

[Detailed description of the invention] Industrial application field The present invention relates to a cleaning device for mechanical parts, electronic parts, medical instruments, etc., and it ensures prevention of solvent diffusion and prevents contact between the object to be cleaned and the solvent. It is an attempt to improve the quality of life.

Conventional technology Conventionally, the object to be cleaned or a cleaning basket containing the object to be cleaned is rotated while being oscillated up and down in the solvent in the cleaning tank to improve the contact between the object to be cleaned and the solvent and improve the cleaning effect. The invention described in JP-A-56-78667 is known. However, in this method, the cleaning table on which the object to be cleaned is placed is moved up and down by a cylinder, so the piston rod of the cylinder moves back and forth in and out of the cleaning tank, causing the solvent attached to the piston rod to diffuse to the outside. In addition, with the reciprocating movement of the piston rod, friction is generated at the portion that contacts the cleaning tank, and this frictional portion generates dust due to abrasion, which is a disadvantage that is undesirable when precision cleaning is performed.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems by shaking the object to be cleaned or the cleaning basket containing the object to be cleaned up and down in a solvent in a cleaning tank. While rotating while maintaining good contact between the object to be cleaned and the solvent, the piston rod does not protrude from the cleaning tank to the outside, reliably preventing the diffusion of the solvent, eliminating worn parts due to friction, and reducing the generation of dust. By preventing this, the object to be cleaned can be precisely cleaned.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A washing stand for placing objects to be cleaned is placed in a washing tank that is sealed from the outside air, and this washing stand is connected to a chain drive mechanism installed inside the washing tank so that it can be moved up and down within the washing tank. At the same time, the driving force of the chain that performs this vertical movement is transmitted to rotating rollers provided on the washing table, and the object to be cleaned can be rotated by the rotation of the rotating rollers. .

Function Since the present invention is constructed as described above, it is possible to vertically swing the cleaning table located in the cleaning tank sealed with the outside air with the object to be cleaned placed on the upper surface of the rotating roller. This is possible by operating a chain drive mechanism installed inside the cleaning tank, but unlike a cylinder mechanism, the chain drive mechanism can be installed without protruding from the cleaning tank, so the cleaning tank is sealed. Cleaning work can be carried out directly, preventing the solvent from spreading to the outside, and since there is no sliding friction between the piston rod and the cleaning tank, precision cleaning of the object to be cleaned is possible without the generation of dust. is possible.

In addition, if the chain driving force that moves the washing table up and down is transmitted to the rotating rollers installed on the washing table, the rotation of the rotating rollers will cause the objects to be cleaned or The cleaning basket containing the items to be cleaned can be rotated, and if this rotation is performed together with the up-and-down movement of the cleaning table, good contact between the solvent and the items to be cleaned can be achieved.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a cleaning tank, which is kept in a sealed state from the outside air, and in order from the bottom, there is a liquid cleaning section 2, a cooling drying section 3, and an object to be cleaned. 4 is provided with a hood section 5 for entering and exiting. A cleaning table 6 for placing the object to be cleaned 4 is placed in the cleaning tank 1, and the cleaning table 6 is slidably attached to a guide frame 7 installed in the vertical direction inside the cleaning tank 1. Connect to the chain drive mechanism 8,
The inside of the cleaning tank 1 can be moved up and down. This chain drive mechanism 8 connects the middle part of a chain 11 fixed to a fixed part 10 in the cleaning tank 1 to a prime mover 12, and engages with a sprocket wheel 13 provided on a cleaning table 6. 13 and the chain 11 in position via the prime mover 12
An induction sprocket wheel 15 to which a weight 14 is fixed is engaged. Further, this chain drive mechanism 8 is connected to the sprocket wheel 1 of the washing table 6.
3 is connected to an auxiliary chain 16, and this auxiliary chain 16 is connected to a rotating roller 17 provided on the washing table 6, and the driving force of the chain drive mechanism 8 that performs vertical movement is transmitted to the rotating roller 17. By this, the circular object to be cleaned 4 placed on the upper surface of this rotating roller 17
Alternatively, the washing basket can be rotated.

In the structure as described above, in order to vertically swing the cleaning table 6 located in the cleaning tank 1 which is sealed from the outside air with the object 4 to be cleaned placed on the upper surface of the rotating roller 17, If the chain drive mechanism 8 installed in the cleaning tank 1 is operated by the prime mover 12, the cleaning platform 6
can swing up and down according to the guide frame 7, and with the operation of the chain drive mechanism 8,
The rotating roller 17 of the washing table 6 is rotated by the auxiliary chain 16.
rotates at the same time, and due to this rotation, rotating roller 1
The object to be cleaned 4 placed on the object 7 or the cleaning basket containing the object to be cleaned 4 can be rotated. Therefore, since the object 4 to be cleaned is rotated and swung up and down, the solvent 18 and the object 4 to be cleaned can be brought into good contact.

Furthermore, unlike conventional cylinder mechanisms, the chain drive mechanism 8 can be installed without protruding from the cleaning tank 1, so cleaning work can be carried out with the cleaning tank 1 sealed, and the solvent 18 can be removed from the outside. In addition, unlike the combination of a piston rod and a cleaning tank, there is no sliding friction, so the object to be cleaned 4 can be precisely cleaned without generating dust due to wear. be.

Effects of the invention Since the present invention is constructed as described above, the object to be cleaned or the cleaning basket containing the object to be cleaned is rotated while being oscillated up and down in the solvent of the cleaning tank.
To ensure good contact between the object to be cleaned and the solvent, and to prevent piston rods etc. from protruding outside from the cleaning tank, reliably preventing diffusion of the solvent, eliminating worn parts due to friction, and preventing the generation of dust. This enables precision cleaning of objects to be cleaned.
