Description

Technical Field

[0001] This utility model relates to the field of fabric inspection technology, and in particular to a clean room for inspecting electronic glass fiber fabric. Background Technology

[0002] Electronic fiberglass cloth is a core material in the manufacture of printed circuit boards, and its quality directly affects the performance of electronic products. With the rapid development of technologies such as 5G, the Internet of Things, and artificial intelligence, the demand for high-performance electronic fiberglass cloth continues to grow. Finished product inspection is a crucial step in ensuring product quality. However, existing inspection machines are placed directly in the workshop to inspect the electronic fiberglass cloth. Because other production processes exist in the workshop, and air purification equipment is lacking, dust in the air adheres to the electronic fiberglass cloth during inspection. This dust cannot be reduced, affecting the product quality. Therefore, a clean environment needs to be provided for the inspection machine in the workshop. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 7 As shown, a clean room for inspecting electronic fiberglass cloth includes a partition 1, a cloth inspection machine support 2, a top cover 3, and a fan 4. The fan 4 is installed on the outside of the partition 1 and is supported above the workshop floor by a fan bracket.

[0029] The enclosure 1 is provided with a doorway 11 for people and equipment to enter and exit. A self-closing door 14 is installed in the doorway 11. When people enter or exit, the self-closing door 14 can close in time to prevent the doorway 11 from being opened due to staff error.

[0030] The enclosure 1 is also provided with an inlet 12 for electronic fiberglass cloth to enter. A flexible transparent baffle 15 covering the inlet 12 is installed on the inner side of the enclosure 1. An inlet guide 17 inclined downward from the outside of the enclosure 1 to the inside of the enclosure 1 is installed at the inlet 12. The inlet guide 17 is located outside the enclosure and its end is bent downward to form a support plate 171.

[0031] When uninspected electronic fiberglass cloth needs to be transported to the cleanroom, it is rolled into the enclosure along the guide plate 17. The flexible transparent baffle 15 opens under the impact of the uninspected electronic fiberglass cloth to allow it to pass through. After the uninspected electronic fiberglass cloth passes through, the flexible transparent baffle 15 returns to its original shape under its own gravity.

[0032] The enclosure 1 is also provided with an outlet 13 for the electronic glass fiber cloth to go out. A flexible transparent baffle 16 covering the outlet 13 is installed on the outside of the enclosure 1. An outlet guide 18 is installed at the outlet 13, which is inclined downward from the inside of the enclosure 1 to the outside of the enclosure 1. The outlet guide 18 is located inside the enclosure 1 and one end is bent downward to form a support plate 181.

[0033] When the inspected electronic fiberglass cloth needs to be transported outside the cleanroom, it is rolled out of the enclosure along the exit guide plate 18. The flexible transparent baffle 16 will open under the impact of the inspected electronic fiberglass cloth to allow it to pass through. After the inspected electronic fiberglass cloth has passed through, the flexible transparent baffle 16 will return to its original shape under its own gravity.

[0034] After production, the electronic fiberglass cloth is rolled into a cylindrical roll and covered with a plastic bag or paper sleeve so that rolling will not damage the electronic fiberglass cloth inside the roll.

[0035] The fabric inspection machine support base 2 is installed in the enclosure 1. A layer of anti-static ventilation base plate 5 is laid on the top of the fabric inspection machine support base 2. The anti-static ventilation base plate 5 ensures that the air in the clean room flows smoothly to the bottom of the anti-static ventilation base plate.

[0036] The fabric inspection machine is placed on the anti-static ventilated base plate 5, and it is ensured that there is a support column of the fabric inspection machine support seat 2 below the part of the fabric inspection machine in contact with the anti-static ventilated base plate 5, so as to avoid the part of the anti-static ventilated base plate 5 in contact with the fabric inspection machine being suspended in the air.

[0037] Multiple return air inlets 6 are installed in the fabric inspection machine support base 2. A stainless steel mesh 61 is installed at the inlet of each return air inlet 6 to prevent large foreign objects from entering. The air inlet of the fan 4 is connected to each return air inlet 6 via a return air duct network 8. The return air duct network 8 includes a primary filter box 81 and multiple return air pipes 82. Multiple inlets 811 are located at the bottom of the primary filter box 81. One end of each return air pipe 82 is connected to an inlet 811, and the other end is connected to a return air inlet 6. An outlet 812 is located at the top of the primary filter box 81 and is connected to the air inlet of the fan 4. Horizontally arranged primary filters 83 are installed in the primary filter box 81. The primary filters 83 perform primary filtration of the passing air, reducing large particulate dust in the air.

[0038] A top cover 3 is installed on the top of the enclosure 1. Multiple evenly distributed air outlets 7 are installed on the top cover 3. The air outlet of the fan 4 is connected to each air outlet 7 via an air supply duct network 9. A high-efficiency filter 93 is installed in the air supply duct network 9. The air supply duct network 9 includes a high-efficiency filter box 91 and multiple air supply pipes 92. An inlet 2 911 is opened at the bottom of the high-efficiency filter box 91, which is connected to the air outlet of the fan 4. Multiple outlets 2 912 are opened at the top of the high-efficiency filter box 91. One end of each air supply pipe 92 is connected to an outlet 2 912, and the other end is connected to an air outlet 7. The high-efficiency filter 93 is installed in the high-efficiency filter box 91 and performs high-efficiency filtration on the passing air, reducing fine particulate dust in the air.

[0039] The enclosure 1 is equipped with multiple glass observation windows 19 to allow staff outside the cleanroom to observe the situation inside the cleanroom, and also to allow staff inside the cleanroom to observe the situation outside the cleanroom, facilitating collaborative work between staff inside and outside the cleanroom and enabling timely rescue in case of an accident.

[0040] An air conditioner 10 is installed on the top cover 3 to regulate the temperature and humidity of the clean room for fabric inspection, providing a suitable working environment for the staff in the clean room.

[0041] As another preferred method, a rubber sealing gasket is sandwiched between the bottom end of the enclosure 1 and the ground to prevent dust in the workshop from entering the enclosure through the gap between the bottom end of the enclosure 1 and the ground, thus avoiding increasing the filtration burden on the pre-filter and the high-efficiency filter.

[0042] A cleanroom is formed by combining a barrier, a support base for the fabric inspection machine, an anti-static ventilation base plate, and a top cover to enclose the fabric inspection machine, preventing the dusty air in the workshop from contaminating the electronic fiberglass cloth on the machine. The air in the cleanroom is extracted, filtered, and then sent back into the cleanroom through a combination of return air vents, return air ducts, fans, supply air ducts, and supply air outlets. The filtration reduces the dust content in the cleanroom air, and the airflow can also carry away some of the dust that was originally attached to the electronic fiberglass cloth, reducing the amount of dust attached to the electronic fiberglass cloth.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
