[0002] Electrolytic copper foil is an important material for copper clad laminate (CCL), printed circuit board (PCB), and lithium-ion battery manufacturing. In today's high-speed development of the electronic information industry, electrolytic copper foil is called the "neural network" for signal and power transmission and communication of electronic products. Since 2002, the production value of printed circuit boards in my country has entered the third place in the world, and copper clad laminate, the substrate material of PCB, has also become the third largest producer in the world. As a result, my country's electrolytic copper foil industry has developed by leaps and bounds in recent years. The production process of electrolytic copper foil is simple, and there are three main processes: solution foil production, surface treatment and product slitting. Its production process seems simple, but it integrates electronics, machinery, and electrochemistry, and is a production process that has particularly strict requirements on the production environment. Therefore, the electrolytic copper foil industry does not have a set of standard universal production equipment and technology, and each manufacturer has its own unique skills, which is also an important bottleneck affecting the domestic electrolytic copper foil production capacity and quality improvement. After the electrolytic copper foil is produced, there will be some pinholes on its surface, and the holes will affect the performance of the electrolytic copper foil, and the part of the electrolytic copper foil containing pinholes needs to be removed.

[0028] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0029] An off-line detection device for pinholes in electrolytic copper foil, comprising:

[0030] Detection device body 1;

[0031] Two slide rails 3 are provided, and the two slide rails 3 are respectively fixedly connected to the inner walls of the detection device body 1 on both sides;

[0032] The clamping assembly is provided with two groups, both of which are arranged in the slide drawer 6, and the two groups of clamping assemblies are used to clamp the electrolytic copper foil sample to be tested;

[0033] An LED light source 2, the LED light source 2 is fixedly connected to the upper inner wall of the detection device body 1; and

[0034] The photosensor 5 is fixedly connected to the lower inner wall of the detection device body 1 .

[0035] In a specific embodiment of the utility model, two slide rails 3 arranged in the main body 1 of the detection device are used to improve the sliding stability of the slide drawer 6. Two groups of clamping components arranged in the slide drawer 6 are used to detect the electrolytic copper foil samples to be detected. The electrolytic copper foil samples are sampled immediately in the production workshop of the electrolytic copper foil without being sent to the laboratory for detection. The use of this device is convenient for pinhole detection of the electrolytic copper foil samples. The detection does not require wiring. The pinhole detection of the electrolytic copper foil samples is completed in an offline state, which effectively improves the detection efficiency of the electrolytic copper foil samples. The LED light source 2 is used to emit a light source. After the clamping component clamps the electrolytic copper foil, the slide drawer 6 is pushed into the slide rail 3. The light source is irradiated on the surface of the electrolytic copper foil. If there are pinholes on the surface of the electrolytic copper foil, the light source passes through the pinholes and irradiates downward, and the light source is captured by the photosensitive sensor 5. If the photosensitive sensor 5 captures the light source, it is judged that there are pinholes on the surface of the electrolytic copper foil, and the electrolytic copper foil is in an unqualified state.

[0036] For details, please refer to Figure 1-Figure 4 Each group of clamping components includes a fixed plate 601, a sliding rod 602, a spring 603 and a pressure plate 604.

The lower part of the pressing plate 604 is provided with anti-slip texture. When it is pressed on the surface of the electrolytic copper foil, the texture increases the friction with the surface of the electrolytic copper foil, improves the stability of the electrolytic copper foil clamping, and through the elastic force of the spring 603, the pressing plate 604 is always in a downward pressed state.

[0038] For details, please refer to Figure 1-Figure 4 The inner wall of the detection device body 1 is fixedly connected with a baffle 4 , and the baffle 4 is fixedly connected to the outer surface of the photosensitive sensor 5 .

[0039] In this embodiment: the surface of the baffle 4 is used to reflect the light source, so that the light sensor 5 can capture the light source.

[0043] In this embodiment: the second handle 606 is convenient for pulling the slide tray 6 out of the detection device body 1 or pushing it into the detection device body 1, and the first handle 605 is convenient for lifting the pressure plate 604, overcoming the elastic force of the spring 603 to pull up the pressure plate 604, so that the electrolytic copper foil to be tested is placed in the slide tray 6.

[0044] For details, please refer to Figure 1-Figure 4 The four corners of the lower end of the detection device body 1 are fixedly connected with supporting feet 10.

[0046] Preferably, a limiting plate 9 is fixed on the surface of the sliding drawer 6, and the limiting plate 9 plays a limiting role.

[0047] It should be noted that the specific types of processing modules, display screens 7, buttons 8, LED light sources 2 and photosensors 5 to be used are selected by relevant technical personnel familiar with the field, and the above-mentioned processing modules, display screens 7, buttons 8, LED light sources 2 and photosensors 5 are all existing technologies and will not be elaborated in this solution.

[0048] The working principle and use process of the utility model are as follows: when the device is in use, the slide drawer 6 is first pulled out from the main body 1 of the detection device, and then the produced electrolytic copper foil is cut, sampled and placed in the slide drawer 6, and the first handle 605 is pulled to overcome the elastic force of the spring 603, and the electrolytic copper foil is pressed on the lower surface of the pressing plate 604.

If there is a pinhole on the surface of the electrolytic copper foil, the light source passes through the pinhole and irradiates downward, and the light source is captured by the photosensitive sensor 5. When the photosensitive sensor 5 captures the light source, it is determined that there are pinholes on the surface of the electrolytic copper foil, and the electrolytic copper foil is in an unqualified state. After receiving the light information, the photosensitive sensor 5 transmits the information to the processing module. After the processing module processes the information, the information is displayed on the display screen 7 for people to view. By using the device, the electrolytic copper foil samples can be sampled immediately in the production workshop of the electrolytic copper foil without sending them to the laboratory for testing. The use of the device is convenient for pinhole detection of the electrolytic copper foil samples. The detection does not require wiring, and the pinhole detection of the electrolytic copper foil samples can be completed in an offline state, effectively improving the detection efficiency of the electrolytic copper foil samples.
