On the other hand, other expressions describing the relationship between the components, such as "between" and "immediately between" or "neighboring to" and "directly neighboring to", should be interpreted as well.

It should be understood that the singular " include "or" have "are to be construed as including a stated feature, number, step, operation, component, It is to be understood that the combination is intended to specify that it does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

In each step, the identification code (e.g., a, b, c, etc.) is used for convenience of explanation, the identification code does not describe the order of each step, Unless otherwise stated, it may occur differently from the stated order. That is, each step may occur in the same order as described, may be performed substantially concurrently, or may be performed in reverse order.

All terms used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. Commonly used predefined terms should be interpreted to be consistent with the meanings in the context of the related art and can not be interpreted as having ideal or overly formal meaning unless explicitly defined in the present application.

1 is a reference diagram showing a general laminator and a vacuum pump line.

The vacuum pump is connected to the outlet of the laminator by a vacuum pipe, and the vacuum pump takes in air through the pipe. Therefore, foreign matters can be directly introduced into the vacuum pump from the discharge port of the laminator, and there is a risk of failure, and there is a problem that the defective rate of the solar cell module produced by the change of vacuum suction force due to such failure increases.

Figure 2 is a reference diagram showing an embodiment of the foreign matter inflow prevention apparatus according to the disclosed technology.

Referring to FIG. 2, the foreign material inflow preventing apparatus 100 may include a first pipe 110, a second pipe 120, and a filter 130.

The foreign material inflow prevention apparatus 100 is comprised in h shape as a whole. In more detail, the foreign material inflow prevention device 100 includes a straight first pipe 110 and a second pipe 120 bent by 90 degrees in a curve. Here, it is preferable that the vacuum degree in the foreign material inflow prevention apparatus 100 maintains the pressure of 100 pa or less.

One end of the first pipe 110 may be sealingly connected to the pipe on the laminator side, and the first pipe 110 may be sealingly connected to one side of the first pipe 110 and the vacuum pump side pipe.

The filter 130 may be located between the first pipe 110 and the second pipe 120. The filter 130 filters out foreign substances introduced into the first pipe 110 from the laminator-side vacuum pipe.

In one embodiment, the filter 130 may be a circular mesh filter having a diameter of 0.1 to 0.5mm. In this case, if the diameter of the filter is too small, the resistance by the fluid (air) may increase, and a load may be generated in the vacuum pump. On the other hand, if the diameter of the filter is too large, foreign matter may not be effectively filtered out, so that the manufacture of the solar cell module This limitation is meaningful when considering foreign substances occurring in the environment.

In one embodiment, the filter 130 may be removable. For example, the filter 130 may include a filter fixing part and a filter part, and the filter fixing part may be sealed and fixed to both pipes between the first and second pipes. The filter fixing part may be designed to open and close to insert or remove the filter.

In one embodiment, the first and second pipes may be formed of SUS304, which is a nonmagnetic stainless steel. This is because SUS304 is relatively stable at temperature, has nonmagnetic properties, and is resistant to corrosion by air and water.

In one embodiment, the foreign matter inflow prevention device may further include a collection pipe 140 for collecting the foreign matter. One end of the collection pipe 140 is connected to the end of the first pipe 110 and the other end is blocked to store foreign substances introduced from the first pipe 110. The collection pipe 140 may be designed to be detachable from the first pipe 110.

In one embodiment, the first tubing 110 may further include a flow control panel 160 to change the flow of the fluid. The flow control panel 160 may have a circular plate shape fixed at an angle in the first pipe 110 so that the fluid flowing from the laminator side may flow to the second pipe 120 side. The flow control panel 160 may protrude to the outside of the first pipe 110 to change the angle. This is to change the angle of the flow control panel 160 in order to change the flow according to the speed of the fluid, since the speed of the fluid is changed according to the vacuum pressure. The flow control panel 160 also serves to prevent foreign substances introduced into the collection pipe 140 flows back to the first pipe 110 back.

In one embodiment, the foreign matter inflow prevention device may further include an opening and closing valve 150 that can open and close the pipe of the foreign matter inflow prevention device 100. In more detail, one end of the on-off valve 150 may be connected to the end of the second pipe 120 and the other end may be connected to the vacuum pump side pipe.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following claims It can be understood that

100: foreign material inflow prevention device 110: first pipe
120: first pipe 130: filter
