DETAILED DESCRIPTION

[0024] like Figures 1 to 5As shown, a copper foil double-sided gloss synchronous detection device disclosed in the present invention includes a first transmission roller 1 and a second transmission roller 2 arranged at the output end of the foil machine for transmitting the copper foil 3. The first transmission roller 1 and the second transmission roller 2 are both cylindrical, and the surface of the transmission roller is in contact with the surface of the copper foil 3. When the transmission roller rotates, the friction between the two causes the copper foil 3 to move along the rotation direction of the transmission roller. Among them, the first transmission roller 1 and the second transmission roller 2 are arranged in parallel and spaced apart on the lower side of the copper foil 3, and the first transmission roller 1 and the second transmission roller 2 are respectively connected to the rotation drive device. In some other embodiments, the transmission drive device uses a motor 19 or other rotation drive components, which can be understood by those skilled in the art.

[0025] Specifically, a tension detection component 4 is installed on the upper side of the copper foil 3 near the first transmission roller 1. The tension detection component 4 is used to detect the tension on the surface of the copper foil 3, mainly used to detect the degree of relaxation of the copper foil 3. When the tension on the surface of the copper foil 3 decreases, the surface of the copper foil 3 becomes loose and concave, and the tension detection component 4 can react, thereby affecting the rotation speed of the second transmission roller 2.

[0026] Among them, the second transmission roller 2 is connected to the speed reduction mechanism 5, and the tension detection component 4 is connected to the speed reduction mechanism 5; when the tension on the surface of the copper foil 3 is reduced, the surface of the copper foil 3 is relaxed and concave, and the tension detection component 4 can react by directly acting on the speed reduction mechanism 5 to accelerate the rotation of the second transmission roller 2 at the far end, so that a speed difference is generated at both ends of the copper foil 3 between the first transmission roller 1 and the second transmission roller 2, which helps to quickly tension the copper foil 3 and avoid the influence of the relaxation of the copper foil 3 on the gloss detection of the copper foil 3.

[0027] In the embodiment of the present invention, an upper gloss detector 6 and a lower gloss detector 7 are respectively installed on the upper and lower sides of the copper foil 3 near the second transmission roller 2; the upper gloss detector 6 and the lower gloss detector 7 respectively detect the gloss of the smooth surface and the rough surface of the copper foil 3, and an additive control end is installed in the foil machine at the same time. The upper gloss detector 6 and the lower gloss detector 7 synchronously detect the gloss of both sides of the copper foil 3, and monitor the change of gloss in real time. When the detection data fluctuates, the gloss data is fed back to the additive control end to adjust the gloss of the copper foil 3. The present invention can change the gloss of both sides of the copper foil 3 in real time by setting a feedback adjustment method, so that the gloss of the copper foil 3 can meet the production requirements and improve product quality.

[0028] In this embodiment, the tension detection assembly 4 includes a roller 8, a connecting rod 10, a pin 11, a support 12, a support plate 13, a pressure head 14, a spring 15, and a support head 16. The surface of the roller 8 contacts the upper surface of the copper foil 3. The center of the roller 8 is rotatably connected to one end of the connecting rod 10. The plane where the connecting rod 10 is located is perpendicular to the copper foil 3. The other end of the connecting rod 10 is fixedly connected to one end of the pin 11. The other end of the pin 11 is connected to a screw 17. When the connecting rod 10 drives the pin 11 to rotate, the pin 11 can drive the screw 17 to rotate.

[0029] Among them, the screw 17 is connected to the speed reduction mechanism 5, the pin 11 is rotatably mounted on the support 12, and the support 12 is also mounted with a support head 16. The middle part of the connecting rod 10 is fixedly connected to the pressure head 14, and the pressure head 14 is connected to the support head 16 through a spring 15. The spring 15 of the present invention provides an elastic supporting force for the connecting rod 10, so that the roller 8 can be close to the surface of the copper foil 3 to adapt to its tension change. When the tension of the copper foil 3 is restored, the tension of the copper foil 3 can compress the spring 15, allowing the roller 8 to return to its original position, so as to facilitate the smooth progress of the next detection cycle.

[0030] In this embodiment, the rotation drive device corresponding to the second transmission roller 2 includes a transmission shaft 18, a motor 19 and a bearing seat 20. The transmission shaft 18 is coaxially connected to the second transmission roller 2 and can rotate with the second transmission roller 2. The bearing seat 20 is used to support the transmission shaft 18 in rotation. The transmission shaft 18 is connected to the output end of the motor 19. When the motor 19 is started, the transmission shaft 18 and the second transmission roller 2 connected thereto can be driven to rotate together. A support platform 21 is installed below the bearing seat 20, and a slide rail 22 is installed on the support platform 21. The bearing seat 20 and the motor 19 are slidably installed on the slide rail 22. After the screw 17 rotates, the second transmission roller 2 can be driven to move toward the side away from the first transmission roller 1.

[0031] In this embodiment, the speed reduction mechanism 5 includes a nut plate 23, a friction roller 24, and an elastic friction component. The nut plate 23 is threadedly connected to the screw 17. The nut plate 23 is also fixedly connected to the bearing seat 20. The friction roller 24 is installed on the transmission shaft 18, and the friction roller 24 is in contact with the elastic friction component. When the pin shaft 11 drives the screw 17 to rotate, the screw 17 acts on the nut plate 23 and drives the nut plate 23 to move. The nut plate 23 drives the transmission shaft 18 to move toward the side away from the first transmission roller 1 through the bearing seat 20, so that the friction roller 24 is away from the elastic friction component. As the friction roller 24 is farther and farther away from the elastic friction component, the friction force it is subjected to is getting smaller and smaller, so that the resistance encountered by the transmission shaft 18 when rotating can be reduced, and the transmission speed can be increased. In the device of the present invention, the friction speed reduction is achieved by the purely physical structure combination of the friction roller 24 and the elastic friction component, which can improve the stability of the device operation.

[0032] In this embodiment, the elastic friction assembly is composed of a plurality of arc-shaped rubber plates 25 stacked along the axial direction of the screw 17. The length of the arc-shaped rubber plates 25 gradually increases. Each arc-shaped rubber plate 25 is connected by a hoop plate 26. The longest arc-shaped rubber plate 25 is connected to a base 28 by a hinge seat 27. The base 28 is installed on the support platform 21. When the elastic friction assembly is pressed tighter, the deformation amplitude of all the arc-shaped rubber plates 25 is greater, and the friction force is greater at this time. On the contrary, when the friction roller 24 is farther away from the elastic friction assembly, the resistance of the second transmission roller 2 is smaller, so that the change of its speed is more obvious.

[0033] In this embodiment, an auxiliary transmission roller 29 is correspondingly installed on the copper foil 3, and the auxiliary transmission roller 29 is installed parallel to the upper side of the second transmission roller 2. The auxiliary transmission roller 29 is coaxially connected with the central shaft 30, and the central shaft 30 is rotatably connected with the synchronous seat 31. Vertical guide rods 32 are fixedly installed on both sides of the bearing seat 20. The upper end of the guide rod 32 slides through the guide hole 33 opened on the synchronous seat 31, and an elastic tension spring 34 is connected between the synchronous seat 31 and the bearing seat 20. By setting the auxiliary transmission roller 29, the copper foil 3 can be transmitted in cooperation with the two transmission rollers, and the transmission is more stable.

[0034] In this embodiment, the pin shaft 11 is connected to the screw rod 17 via a reducer 35, so that the relative rotation speed of the two can be changed.

[0035] In this embodiment, the pin 11 is also connected to a sensor, and the sensor is connected to a servo motor 36 through a controller. The output end of the servo motor 36 is connected to a gear 37, and the gear 37 is meshed with a rack 38. The rack 38 is slidably arranged on the support platform 21, and the rack 38 is simultaneously connected to the upper gloss detector 6 and the lower gloss detector 7 through a bracket 39. When abnormal tension is detected, the second transmission roller 2 accelerates the rotation, so that a section of copper foil 3 is quickly transmitted. The screw 17 simultaneously transmits a signal to the controller, and the controller drives the servo motor 36 to move, so that the upper gloss detector 6 and the lower gloss detector 7 connected thereto are simultaneously displaced in the longitudinal direction, increasing the relative time of the upper gloss detector 6 and the lower gloss detector 7 to detect the upper section of copper foil 3, so that the detection time remains sufficient to ensure the accuracy of the detection result. After the detection is completed, the servo motor 36 controls the upper gloss detector 6 and the lower gloss detector 7 to return to their original positions.

Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
