Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary production equipment for electrolytic copper foil, and in particular to a device for online detection of the surface gloss of electrolytic copper foil. Background Technology

[0002] In the production process of electrolytic copper foil, surface gloss is one of the important indicators for measuring the quality of copper foil, directly affecting its application performance in fields such as electronic circuits and lithium batteries. Traditional gloss testing usually adopts manual offline testing methods, which have drawbacks such as low testing efficiency, large human error, and inability to provide real-time feedback on production status, making it difficult to meet the high precision and high efficiency requirements of modern large-scale production for quality control. To address this, some researchers have invented online gloss testing devices based on electrolytic copper foil production lines. For example, Chinese utility model patent CN219552256U discloses an online gloss testing device for electrolytic copper foil, which, by setting up a set of matte gloss meters and a set of smooth gloss meters, can test the gloss of newly produced copper foil and achieve real-time detection of the gloss of copper foil at different times and locations. However, this device is not convenient for flexibly adjusting the distance and angle between the gloss meter and the copper foil, which can easily affect the accuracy and stability of the test results due to unsuitable distance and angle. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing an online detection device for the surface gloss of electrolytic copper foil, which features a more rational structural design, allows for convenient adjustment of the distance and angle between the device and the copper foil, and offers higher detection accuracy and stability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an online gloss detection device for electrolytic copper foil surface, comprising a gloss detector, a horizontal moving mechanism, and an angle adjustment mechanism. The horizontal moving mechanism is mounted on a base, and the entire device is mounted on the foil-making machine frame via the base. The angle adjustment mechanism is mounted on the horizontal moving mechanism to form a structure that can move horizontally relative to the copper foil. A movable support is mounted on the angle adjustment mechanism via a rotating shaft pin, and the rotating shaft pin is connected to the angle adjustment mechanism to achieve rotation. The gloss detector is mounted on the movable support to form a structure that can adjust the pitch angle towards the copper foil. An adjustment knob is provided on the angle adjustment mechanism, and the pitch rotation of the movable support is achieved by rotating the adjustment knob.

[0005] Furthermore, the horizontal moving mechanism adopts a sliding moving structure of linear slide rail and slide block. The linear slide rail is installed on the base, the slide block is mounted on the linear slide rail, and the angle adjustment mechanism is installed on the slide block.

[0006] Furthermore, the horizontal moving mechanism adopts a moving structure with a lead screw and a guide rod. The lead screw and the guide rod are mounted on the base, and the angle adjustment mechanism is connected to the lead screw through a nut and sleeved with the guide rod through a sliding sleeve.

[0007] Furthermore, a locking knob is provided on the side of the slide block. By tightening the locking knob, the slide block is locked onto the linear slide rail to fix the horizontal position of the gloss meter.

[0008] Furthermore, the angle adjustment mechanism adopts a worm gear-worm type adjustment structure. The adjustment knob extends into the angle adjustment mechanism from the front and connects with the worm. The worm gear meshes perpendicularly with the worm from above. The rotating shaft pins on both sides extend into the angle adjustment mechanism from both sides and connect with the worm gear.

[0009] Furthermore, the movable support has an inverted U-shaped structure, and a U-shaped fixed support is installed on the movable support; a connecting rod is provided at the bottom of the gloss meter, and the connecting rod is embedded in the fixed support and fixed by two fixed shaft pins to form an inclined posture.

[0010] Furthermore, a positioning transmission mechanism is provided on both sides of the gloss meter. The positioning transmission mechanism includes a positioning transmission wheel, a crank arm, and a connecting shaft. The connecting shaft is connected to the gloss meter and extends outward. One end of the crank arm is perpendicularly connected to the connecting shaft to form a rotatable structure. The positioning transmission wheel is perpendicularly connected to the other end of the crank arm through a rotating shaft.

[0011] Furthermore, a protective cover is provided on the side of the gloss meter facing the copper foil, covering the gloss meter; the protective cover covers the detection window of the gloss meter, and the detection window shines on the copper foil through the protective cover.

[0012] This invention, when integrated into a production line, enables continuous online detection of the gloss level of electrolytic copper foil surfaces, eliminating the need for manual sampling, significantly improving detection efficiency, shortening the detection cycle, and meeting the real-time monitoring requirements of large-scale production. Simultaneously, mechanical adjustment mechanisms (such as linear guides and angle adjustment mechanisms) allow for precise and flexible adjustment of the detection position and angle. Combined with the high-precision optical detection of an automatic gloss level detector, it effectively reduces errors caused by copper foil transport deviations and improper detection angles, improving the accuracy and stability of the detection results.

Detailed Implementation

[0015] In this embodiment, refer to Figure 1 and Figure 2 The online gloss detection device for electrolytic copper foil includes a gloss meter 5, a horizontal moving mechanism, and an angle adjustment mechanism 2. The horizontal moving mechanism is mounted on a base 1, and the entire device is mounted on the foil-making machine frame via the base 1. The angle adjustment mechanism 2 is mounted on the horizontal moving mechanism to form a structure that can move horizontally relative to the copper foil 8, which is guided by guide rollers 9. A movable support 3 is mounted on the angle adjustment mechanism 2 via a rotating shaft pin 31. The rotating shaft pin 31 is connected to the angle adjustment mechanism 2 to achieve rotation. The gloss meter 5 is mounted on the movable support 3 to form a structure that can adjust the pitch angle towards the copper foil 8. An adjustment knob 21 is provided on the angle adjustment mechanism 2, and the pitch rotation of the movable support 3 is achieved by rotating the adjustment knob 21.

[0016] The horizontal moving mechanism employs a sliding structure with a linear slide rail 11 and a slide block 12. The linear slide rail 11 is mounted on the base 11, perpendicular to the guide roller 9. The slide block 12 is mounted on the linear slide rail 11, and the angle adjustment mechanism 2 is mounted on the slide block 12. This horizontal moving mechanism allows for horizontal position adjustment of the detection device, ensuring that the detection window 53 of the gloss meter 5 is accurately aligned with the detection area of ​​the copper foil 8. This is particularly suitable for detecting copper foils of different widths or positions. The detection window 53 is made of a light-transmitting and wear-resistant material to ensure stable light transmission and detection accuracy.

[0017] Alternatively, the horizontal movement mechanism can also employ a lead screw and guide rod movement structure, with the lead screw and guide rod mounted on the base 1. The angle adjustment mechanism 2 is connected to the lead screw via a nut and sleeved with the guide rod via a sliding sleeve. This structure can directly utilize existing technology and is not shown in the figure.

[0018] A locking knob 22 is provided on the side of the slide 12. After it is moved into place, the slide 12 is locked on the linear slide rail 11 by tightening the locking knob 22, so that the horizontal position of the gloss meter 5 can be fixed and it will not move.

[0019] The angle adjustment mechanism 2 employs a worm gear-worm type adjustment structure. The adjustment knob 21 extends into the angle adjustment mechanism 2 from the front and connects to the worm. The worm gear meshes perpendicularly with the worm from above. Rotary shaft pins 31 on both sides extend into the angle adjustment mechanism 2 from the sides and connect to the worm gear. Rotating the adjustment knob 21 causes the worm to rotate, which in turn drives the worm gear to rotate, thereby causing the rotating shaft pins 31 to rotate. This, in turn, causes the movable support 3 and the gloss meter 5 to rotate together, thus adjusting the tilt angle of the gloss meter 5. This ensures that the detection window 53 of the gloss meter 5 maintains the optimal detection angle (usually a specific standard angle, such as 60 degrees, 20 degrees, or 85 degrees, which can be flexibly adjusted according to the detection standard) with the surface of the copper foil 8, ensuring that the optical detection element can receive a stable reflected light signal and improving detection accuracy.

[0020] Of course, this worm gear-worm type adjustment structure is existing technology, and many existing technologies disclose similar structures for adjusting pitch angles. Therefore, its specific structure is not illustrated in this utility model. For example, Chinese utility model patent CN202420870230.2 discloses a control device for a multifunctional intelligent exhibition hall, and Chinese utility model patent CN201820161892.7 discloses a basketball shooting equipment, etc., all of which use a worm gear and worm for angle adjustment.

[0021] The movable support 3 has an inverted U-shaped structure, and a U-shaped fixed support 4 is installed on the movable support 3; a connecting rod 52 is provided at the bottom of the gloss meter 5, and the connecting rod 52 is embedded in the fixed support 4 and fixed by two fixed shaft pins 41 to form an inclined posture so as to better fit the copper foil 8.

[0022] Positioning transmission mechanisms are provided on both sides of the gloss meter 5. Each positioning transmission mechanism includes a positioning transmission wheel 71, a crank arm 72, and a connecting shaft 73. The connecting shaft 73 is connected to the gloss meter 5 and extends outwards. One end of the crank arm 72 is perpendicularly connected to the connecting shaft 73, forming a rotatable structure. The positioning transmission wheel 71 is perpendicularly connected to the other end of the crank arm 72 via a rotating shaft. By rotating the crank arm 72, the positioning transmission wheel 71 can protrude towards the copper foil 8 and press against its surface. The positioning transmission wheel 71 is then driven by a motor, which helps ensure the stability and tension uniformity of the copper foil 8 during transport, preventing the detection results from being affected by the copper foil 8's vibration or displacement.

[0023] A protective cover 6 is provided on the side of the gloss meter 5 facing the copper foil 8, covering the gloss meter 5. The protective cover 6 covers the detection window 53 of the gloss meter 5, through which light shines onto the copper foil 8. The display screen 51, adjustment buttons, data transmission buttons, etc. of the gloss meter 5 are located on the back. The protective cover 6 can prevent dust, oil, and other impurities from contaminating the detection window 53 or optical components during the production process, and at the same time, it provides a certain degree of protection for the detection module, extending the service life of the equipment.

[0024] The data display screen 51 is used to display information such as the detected copper foil surface gloss value, detection time, and equipment operating status in real time, so that operators can intuitively monitor the detection process.

[0025] The data transmission button triggers data transmission. When this button is pressed, the detected gloss data is transmitted through a data transmission port (such as a USB interface or Ethernet interface) to an external data processing device (such as an industrial computer or cloud server) for data storage, analysis, and remote monitoring. The external system can analyze the data according to preset quality standards. If the detected value exceeds the allowable range, it can automatically trigger an alarm or send adjustment commands to the production control system, achieving closed-loop quality control.

[0026] Testing process 1. During the electrolytic copper foil production process, the copper foil 8 is conveyed to the detection area at a constant speed through the cooperation of the guide roller 9 of the foil production machine and the positioning transmission wheel 71.

[0027] The gloss meter 5 scans the surface of the copper foil 8 in real time through the detection window 53. The optical detection element collects the reflected light signal from the surface of the copper foil and converts it into an electrical signal, which is then transmitted to the signal processing module inside the instrument.

[0028] The signal processing module amplifies, filters, and performs analog-to-digital conversion on the electrical signal, calculates the gloss value of the copper foil surface, and displays it in real time on the data display screen.

[0029] Operators can monitor gloss data in real time via the data display screen 51. If abnormal data is detected (such as exceeding the quality standard range), the process parameters of the foil-making machine (such as current and electrolyte concentration) can be adjusted through the external control system. At the same time, pressing the data transmission button will transmit the test data to the data center or cloud server through the data transmission port for quality management personnel to perform statistical analysis and quality traceability.

[0030] When it is necessary to adjust the distance between the gloss meter 5 and the copper foil 8, the angle adjustment mechanism 2 can be manually pushed to slide along the linear slide rail 11, moving closer to or further away from the copper foil 8. After adjustment, tighten the locking knob 22 to position it.

[0031] When it is necessary to adjust the pitch angle of the gloss meter 5, turn the adjustment knob 21 clockwise or counterclockwise. The angle adjustment mechanism 2 will tilt the gloss meter forward or backward, thereby adjusting its pitch angle.

[0032] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
