[0047] The following is a non-limiting detailed description of the technical solution of this application in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0048] Example 1: A copper foil tension detection device

[0049] As attached Figure 1-4 As shown, a tension detection device for copper foil includes: a support table 1;

[0050] (1) Two brackets 1 2 are installed on the upper surface of the support platform 1. The brackets 1 2 support the smoothing rollers 3. Two smoothing rollers 3 arranged up and down are installed between the two brackets 1 2. The smoothing rollers 3 smooth the copper foil.

[0051] (2) The lower portion of the electric push rod 4 is fixed to the upper surface of the support platform 1 , and the upper portion (moving end) of the electric push rod 4 is fixedly provided with a bracket 3 , and the bracket 3 is rotatably provided with a moving roller 5 .

[0052] (3) The upper surface of the support platform 1 is provided with: a rear bracket 2 6-1, a front bracket 2 6-2; the rear bracket 2 6-1 and the front bracket 2 6-2 are fixedly connected to the support platform 1; a rotating shaft 8 is rotatably provided between the rear bracket 2 6-1 and the front bracket 2 6-2; a motor 10 is installed on the rear side of the fixed bracket 2 6-1, and the output shaft of the motor 10 is connected to one end of the rotating shaft 8 (that is, the motor 10 drives the rotating shaft 8 to rotate); a movable cylinder 7 is provided on the outer side of the rotating shaft 8 through a limiting component; a mounting plate 15 is fixedly installed on the rear side of the movable cylinder 7, and the upper surface of the mounting plate 15 Two telescopic rods 16 are installed, and an arc-shaped pressing plate 14 is installed at the end of the telescopic shaft of the telescopic rod 16. The outer side of the telescopic rod 16 is sleeved with a spring 17 whose two ends are respectively fixedly connected to the pressing plate 14 and the mounting plate 15. By setting the pressing plate 14 and the spring 17, the two springs 17 are fixed to one side of the movable cylinder 7 using the mounting plate 15. Combined with the action of the pressing plate 14, one end of the copper foil is fixed to the movable cylinder 7, thereby facilitating the winding of the copper foil after the inspection is completed. Combined with the telescopic action of the telescopic rod 16, the interior of the spring 17 is filled, thereby improving the stability of the spring 17 during operation.

[0053] (4) Among them, the smoothing roller, the moving roller and the movable cylinder are arranged in parallel.

[0054] (5) A scale plate 21 is provided on the rear side of the electric push rod 4 , and the scale plate 21 is fixedly connected to the support platform 1 .

[0055] (6) An L-shaped lighting frame 22 is installed on the upper surface of the support table 1, and a plurality of light tubes 23 are installed on the lower surface of the lighting frame 22. The light tubes 23 are located above the moving roller 5, the smoothing roller 3 and the movable cylinder 7. By setting the light tubes 23 and fixing the light tubes 23 above the moving roller 5, the smoothing roller 3 and the movable cylinder 7 using the lighting frame 22, it is convenient to illuminate the moving roller 5, the smoothing roller 3 and the movable cylinder 7 through the action of the light tubes 23 in dim light conditions, thereby facilitating the inspection of the copper foil by the staff at any time.

[0056] Through the action of two smoothing rollers 3, the copper foil entering the copper foil tension detection equipment is smoothed (also pressed), and the electric push rod 4 drives the movement of the moving roller 5 to stretch and lift the copper foil upward, thereby detecting the tension of the copper foil. It can be visually checked whether the copper foil has collapsed edges or wavy edges. With the help of the scale, it is convenient to understand the tension tolerance height of the copper foil, thereby greatly improving the production efficiency and detection speed of the copper foil.

[0057] It should be noted that the position limiting assembly includes two clips 11, which limit the position of the movable cylinder 7. Slots are provided on the left and right sides of the rotating shaft 8, and the two clips 11 are respectively located in the two slots. One end of the clip 11 is fixedly connected to the movable cylinder 7. By providing the clips 11 and utilizing the action of one end of the clip 11 in the slot, the movable cylinder 7 is limited in position. When the rotating shaft 8 rotates, the clips 11 limit the position of the movable cylinder 7, driving the movable cylinder 7 to rotate and rewind the copper foil. Combined with the action of the clips 11, the movable cylinder 7 can be easily disassembled at a later time, thereby increasing the applicability of the device.

[0058] It should be noted that: a groove is provided on the front side of the rotating shaft 8, and a support rod 9 is arranged in the groove. The support rod 9 and the front side of the rotating shaft 8 adopt a detachable design (such as a thread is provided in the groove of the rotating shaft 8, and a thread is provided on the outer surface of the support rod 9). One end of the support rod 9 extends through the through hole provided on the front bracket 2 6-2.

[0059] When using the copper foil tension testing device of the present application, the steps are as follows:

[0060] S100, one end of the copper foil passes through two smoothing rollers 3, and then the copper foil continues to move, and finally the other end of the copper foil is pressed onto the movable cylinder 7 by the pressing plate 14;

[0061] The process of pressing the other end of the copper foil onto the movable cylinder 7 through the pressing plate 14 is as follows:

[0062] S101, moving the pressing plate 14 upward;

[0063] S102, passing one end of the copper foil through the pressing plate and placing it on the movable cylinder 7;

[0064] S103, loosen the pressing plate 14; the pressing plate 14 is pulled by the spring 17 to press and fix the copper foil;

[0065] S200, starting the motor 10, causing the movable drum 7 to reel the copper foil (the movable drum 7 rotates less than 360°): the motor 10 drives the rotating shaft 8 to rotate, which in turn drives the clamping plate 11 to rotate, thereby driving the movable drum 7 to rotate through the limiting effect of the clamping plate 11, and the movable drum 7 reels the copper foil;

[0066] S300, start the electric push rod 4 to drive the moving roller 5 to move upward: the moving roller 5 lifts the copper foil upward (the copper foil is in a stretched state at this time), and close the electric push rod 4 when the moving roller 5 stops at an appropriate height;

[0067] S400, check whether there is any collapse or wavy edge on the edge of the copper foil.

[0068] The above embodiments are preferred implementation modes of the present application and are only used to facilitate the explanation of the present application. They are not intended to limit the present application in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present application, can make partial changes or modifications to the technical contents disclosed in the present application, and they are still within the scope of the technical features of the present application without departing from the technical features of the present invention.
