Abstract

PURPOSE:To clean laminated jigs without wearing the surfaces by injecting a high-pressure cleaning liquid from the tips of nozzles toward the laminated jig on a conveyor, moving the nozzles back and forth in the progressing direction of the conveyor and feeding drying air above the conveyor. CONSTITUTION:The laminated jigs 2 are carried by the conveyor 1 and the high-pressure cleaning liquid is injected from the tips of the nozzles 3 of a water jet 5 in the direction above the conveyor 1. The nozzles 3 are moved back and forth in the progressing direction of the conveyor 1 and the drying air is delivered in the direction above the conveyor 1 by a fan 4. Namely, the surfaces of the laminated jigs can be cleaned by automatic cleaning without polishing the surfaces hence without wearing said surfaces. The life of the jigs is thus prolonged. Even the jigs the surfaces of which are not flat are cleanable with good workability.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cleaning device for jigs in the lamination step of a multilayer printed wiring board manufacturing process, and particularly to a cleaning device for jigs that is excellent in cleaning performance and workability.

[Conventional technology]

As shown in FIG. 4, the conventional cleaning device for laminating jig 2 removes dirt 11 such as resin adhered to the surface of laminating jig 2 using a brass spatula 1.
0, it will be removed with a large amount of work. However, with the recent automation of work, a lamination jig cleaning device using a polishing device has been proposed. This cleaning device is the third
As shown in the figure, the laminated jig 2 is placed on the conveyor 1 and conveyed, hot water is supplied from the nozzle 3 of the hot water device 7, the hot water is applied to the jig surface and the puff 8, and the jig surface is moistened by the puff 8. This is to remove dirt such as resin on the surface of the jig. This conventional cleaning device can automatically clean using puff polishing, improving work efficiency and cleaning the jig surface.
This has the advantage of improving the surface finish of the laminate.

[Problem to be solved by the invention]

However, in the above-mentioned cleaning device using puff polishing, the jig surface is ground and the jig surface is worn out in order to polish the jig surface, which has the disadvantage of shortening the life of the jig. Furthermore, in the case of a jig with a handle 9 as shown in FIGS. 4 and 5, it is difficult to polish the jig because the surface to be polished is not flat.

An object of the present invention is to solve the above-mentioned problems by using a laminated jig cleaning device.
1.

[Differences between the invention and the prior art]

In contrast to the cleaning device using the polishing device described above, the present invention automatically cleans the jig without polishing the jig surface, thereby preventing wear on the jig surface and improving the life of the jig.
The difference is that even jigs with non-flat surfaces, such as jigs with handles, can be easily cleaned.

[Means to solve the problem]

In order to achieve the above object, the laminated jig cleaning device of the present invention includes a mechanism for transporting the laminated jig by a conveyor;
It has a mechanism that injects high-pressure cleaning liquid from the tip of the nozzle onto the conveyor, a mechanism that moves the nozzle back and forth in the direction of movement of the conveyor, and a mechanism that sends dry air toward the conveyor. be.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

(Example 1) FIG. 1 is a sectional view showing a first embodiment of the present invention.

In the figure, a conveyor 1 is laid horizontally in an endless manner on a stage 11, and two machine frames 12a and 12b are arranged in parallel in the front and back along the conveyance direction of the conveyor 1. A water jet 5 that injects high-pressure cleaning liquid toward the conveyor 1 from its tip is supported by a pulley 6 and installed so as to be able to reciprocate in the transport direction of the conveyor 1. A blower 4 that blows air is installed.

In the embodiment, first, the stacking jig 2 used for stacking is placed on the conveyor 1 and conveyed. Transported lamination jig 2
When it comes under the water jet 5, the temperature from the tip of the nozzle 3 is 70 to 90°C and the pressure is 150 to 200 kg/a.
At J, the surface of the jig is sprayed with high temperature water, and dirt 11 such as resin attached to the surface of the lamination jig 2 is removed. As shown in FIG. 2, the nozzle 3 of this water jet 5 is reciprocated by a pulley 6 in the direction in which the lamination jig 2 moves.

Next, the lamination jig 2 is placed under the blower 4, and the surface of the jig 2 is dried.

(Example 2) As Example 2 of the present invention, in the laminated jig cleaning apparatus shown in FIG. ℃
), an organic solvent (dimethylformamide) is sprayed onto the surface of the jig 2 at a pressure of 100 to 150 kg/a# to form the laminated jig 2.
Wash. In this embodiment, the resin adhering to the surface of the jig 2 is dissolved by using an organic solvent (dimethylformamide) as the cleaning liquid, so there is an advantage that the adhering resin can be easily removed.

〔Effect of the invention〕

As described above, the present invention automatically cleans the surface of the laminated jig without polishing it, thereby making it possible to clean the jig surface without abrasion, thereby extending the life of the jig. Furthermore, even a jig with a non-flat surface can be cleaned with good workability, and the surface finish of the laminate can be improved.
