Description

Foreign matter removal device and clean bench including the same {Particle removal device and clean bench including the same}

The present invention relates to a clean bench provided to remove foreign substances existing inside and outside of a product. More particularly, it relates to a foreign material removal device for reducing foreign substances present inside and outside a product including a connector when assembling a connector, and a clean bench including the same.

A clean bench is a device formed to reduce the number of foreign substances contained in a product during manufacturing by removing foreign substances inside and outside the product or by suppressing the inflow of foreign substances into the product. In general, a clean bench is configured in such a way that air is blown toward the finished product or the product being assembled through a blower to blow off the dust attached to the product.

Specifically, the mini clean bench disclosed in Patent Document 1 below has a structure in which a filter capable of removing fine dust contained in the air is mounted between an air inlet and an air outlet. In addition, Patent Document 2 below discloses a clean bench having a structure in which a corner portion of a work space is rounded to suppress the occurrence of vortices in the work space. In addition, Patent Document 3 below discloses a clean bench capable of sterilizing air in addition to removing fine dust in the air.

However, such a conventional clean bench can only remove foreign substances on the outside of the product and cannot remove foreign substances inside the product. Also, through an opening on the workbench that blows foreign substances on the outside of the product by driving a blower, the surrounding air is indiscriminately discharged. There is a problem with the inflow.

On the other hand, an example of the product is a connector. A connector means a terminal connected to a wire in a housing combined, and refers to an electrical device that conducts electricity between two circuits. Here, the housing functions to protect the terminals, and in general, foreign substances such as dust may be introduced into the housing during the manufacturing and assembling process of each part.

Meanwhile, the recent German Automobile Industry Association quality standard (VDA 19 Part 2) suggests the recommended quantity for each size of particle inside the connector, and requires that it be maintained below the recommended quantity to improve the quality of wiring. . However, the current automobile wiring harness manufacturing and connector assembly work is not carried out in a strictly controlled state like a clean room, and there is no separate means to remove foreign substances inside the wiring harness and the connector connected to each wire terminal. the current situation.

20 is a flowchart of a method of using a clean bench of the present invention, and FIG. 21 is a driving flowchart of the clean bench. With reference to this, a method of removing foreign substances in the product will be described. An example of a product is a connector.

First, the method of using the clean bench of the present invention is described. First, the upper jig 411 and the lower jig 412 are opened and the connector is mounted on the jig part 410 (S1). Thereafter, the jig unit 410 is moved to the jig installation frame 312 of the cradle 310 using the moving handle 418 and assembled using the fixing handle 315 (S2). Then, by using the control unit 500 to set the output values, output duration, etc. of the main blower, the door 330, the air gun 440, etc. in the setting mode 530 to drive the clean bench in the automatic mode 550, or , to drive the clean bench in the manual mode (540). When driving in the automatic mode 550, the "START" button of FIG. 17 can be clicked (S3). After that, the jig part 410 is removed from the cradle 310 (S4), and the connector is removed from the jig part 410 (S5).

In step S3 of driving the clean bench, the clean bench is operated in the following order. First, the door 330 descends to block the mounting unit 300 from the outside (S31), and the main blower 210, the air gun 440 and the mobile robot 420 are operated (S32), and the set time passes or when a stop signal is generated, the mobile robot 420, the air gun 440 and the main blower 210 are stopped (S33). After that, the door 330 is raised and opened so that the connector can be removed or the position of the foreign material removal device 400 can be rearranged (S34).

In the present specification, although each configuration of an embodiment of the present invention has been described separately, embodiments that can be derived by combining some configurations also fall within the scope of the present invention.

The above description is merely illustrative of the technical idea of the present invention, and those of ordinary skill in the art to which the present invention pertains can make various modifications and variations without departing from the essential characteristics of the present invention. The scope of protection should be construed by the following claims, and all technical ideas within the equivalent range should be construed as being included in the scope of the present invention.
