Description

Technical Field

[0001] This utility model relates to the field of laminate detection technology, specifically to an inhalation-type detector for detecting pyrolysis particles in copper-clad epoxy fiberglass laminates. Background Technology

[0002] Copper-clad epoxy fiberglass laminate is a common electronic material widely used in printed circuit board manufacturing. It consists of fiberglass cloth and epoxy resin with a copper foil sandwiched in between. It is commonly used in electronic devices requiring high strength and durability. Copper-clad epoxy fiberglass laminate possesses high tensile strength and heat resistance, maintaining stable mechanical properties even at high temperatures. It is an excellent insulating material suitable for electrical isolation and is widely used in the production of electronic components and circuit boards. Epoxy resin exhibits strong resistance to most chemicals, enabling copper-clad epoxy fiberglass laminate to be used stably for extended periods under harsh environmental conditions. Due to its low hygroscopicity, copper-clad epoxy fiberglass laminate can be used for long periods in humid environments without being easily affected by moisture, thus preventing degradation of its electrical performance.

[0003] Copper-clad epoxy fiberglass laminates undergo pyrolysis at high temperatures, releasing tiny particles or gases that can harm human health. Conventional particle detectors struggle to clean their internal sensors, and after a period of operation, the accumulation of tiny particles on the sensor surface reduces sensitivity, leading to significant discrepancies between the detector's readings and actual results. Furthermore, disassembling or replacing the sensor is time-consuming and increases testing costs. At lower ambient temperatures, conventional particle detectors cease operation, allowing fine dust to enter and adhere to the sensor surface, further reducing sensitivity. To address these issues, a novel suction-type pyrolysis particle detector for copper-clad epoxy fiberglass laminates is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, an inhalation-type pyrolysis particle detector for copper-clad epoxy fiberglass laminates is provided. This solves the problem that current copper-clad epoxy fiberglass laminates undergo pyrolysis at high temperatures, releasing tiny particles or gases that can harm human health. Furthermore, conventional particle detectors are difficult to clean internal sensors, and after a certain period of operation, tiny particles adhering to the sensor surface can reduce sensor sensitivity, leading to significant discrepancies between the detector's test results and actual results. Additionally, disassembling or replacing the sensor is time-consuming and increases testing costs. At low ambient temperatures, conventional particle detectors cease operation, allowing fine dust from the environment to enter the detector and adhere to the sensor surface, further reducing sensor sensitivity.

By setting up an air inlet hopper, card slot, fixed plate, push rod and sealing plate, when the particle detector stops working, it can effectively prevent tiny dust particles in the environment from entering the detector and adhering to the sensor surface, thus avoiding the reduction of sensor sensitivity.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Reference Figure 1-2 As shown, an inhalation-type detection copper-clad epoxy fiberglass cloth laminate pyrolysis particle detector includes a housing 1. A touch screen 2 is fixedly connected to the center of the front side of the housing 1 for inputting commands and displaying detection results. A filter box 3 is fixedly connected to the upper right end of the housing 1 to effectively filter dust in the air. An air inlet 4 is opened through the lower right end of the filter box 3. An air inlet pipe 5 is fixedly connected to the lower left end of the filter box 3. An air pump 6 is fixedly installed on the upper left end of the housing 1 to effectively deliver clean air with a certain pressure into the fixed pipe 13 to effectively clean the sensor. The input end of the air pump 6 is fixedly connected to the left side of the air inlet pipe 5. A control pipe 7 is fixedly connected to the output end of the air pump 6. A first electromagnetic valve 8 is fixedly installed on the control pipe 7.

[0017] A detection module 9 is fixedly installed at the lower end of the interior of the housing 1. A particle sensor is fixedly installed inside the detection module 9 to effectively detect minute particles and gases. An exhaust pipe 10 is fixedly connected to the right side of the detection module 9. The right end of the exhaust pipe 10 penetrates the right side panel of the housing 1 and extends to the right side of the housing 1. A fan 11 is fixedly installed inside the right end of the exhaust pipe 10 to allow minute particles and gases to be drawn into the housing 1. A second solenoid valve 12 is fixedly installed on the exhaust pipe 10. A fixing pipe 13 is fixedly connected to the left side of the detection module 9. The left end of the fixing pipe 13 penetrates the left side panel of the housing 1 and is fixedly connected to an air inlet. 14. The rotation of the fan 11 allows tiny particles and gases to enter the detection module 9 through the air inlet hopper 14 for detection. The lower end of the control tube 7 is connected to the interior of the fixed tube 13. A slot 15 is provided on the left side of the interior of the air inlet hopper 14. A fixed plate 16 is fixedly connected to the middle of the interior of the air inlet hopper 14. A push rod 17 is fixedly installed at the center of the right side of the fixed plate 16. A baffle 18 is fixedly connected to the upper right side of the fixed plate 16. The output end of the push rod 17 passes through the right side of the fixed plate 16 and is fixedly connected to a sealing plate 19 to seal the air inlet hopper 14 and prevent dust from entering the interior of the detection module 9 and contaminating the sensor.

[0018] Working principle: When the particle detector stops working, the push rod 17 drives the sealing plate 19 to move to the right and engage with the inside of the slot 15, effectively preventing fine dust from entering the detection module 9 from the air inlet 14. At the same time, the second solenoid valve 12 closes to prevent fine dust from entering the detection module 9 from the exhaust pipe 10. Cleaning commands can be input on the touch screen 2. When cleaning, the sealing plate 19 engages with the inside of the slot 15, the air pump 6 works, the first solenoid valve 8 and the second solenoid valve 12 open, and air enters the filter box 3 from the air inlet 4. After filtering out the dust in the air, it enters the fixed pipe 13 through the control pipe 7. The clean air enters the inside of the detection module 9, carrying away the fine particles attached to the sensor surface and being discharged through the exhaust pipe 10. The right end of the exhaust pipe 10 can be connected to an external purification device to prevent fine particles from directly entering the air and causing air pollution.
