[0048] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] As mentioned in the above background technology, in the production process of copper foil, electrolysis is usually used. After the copper foil is generated on the surface of the cathode roller, it is transferred out of the electrolyte. After the copper foil is generated, the copper foil needs to be automatically rolled up to facilitate the cathode roller to continue electrolyzing and generating copper foil. In the process of copper foil rolling, it is necessary to sample the copper foil to detect the qualified rate of the copper foil. At present, copper foil sampling is usually performed manually. However, manual sampling is time-consuming and labor-intensive, and the sampling length is difficult to accurately control, which reduces the accuracy and efficiency of copper foil sampling.

[0050] Based on the above problems, the embodiment of the present application provides a copper foil sampling device, which is provided by rotating a sampling roller and a winding roller on a rotating base. The rotating base can be rotated to switch the winding roller and the sampling roller in the winding position in turn, so that the sampling roller can sample the copper foil. Moreover, by providing a detection device for detecting the winding length of the copper foil on the winding roller, the copper foil sampling length of the sampling roller can be accurately measured. In this way, the copper foil can be accurately sampled without manual participation, which can effectively reduce human labor, reduce the difficulty of copper foil sampling, and effectively improve the accuracy of copper foil sampling.

[0051] The copper foil sampling device provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0052] Figure 1 A schematic diagram of the structure of a copper foil sampling device provided in an embodiment of the present application, Figure 2 A side view of a copper foil sampling device provided in an embodiment of the present application in a first state, Figure 3 A side view of a copper foil sampling device provided in an embodiment of the present application in a second state.

[0053] The present application embodiment provides a copper foil sampling device 100, see Figure 1 As shown, the copper foil sampling device 100 may include a rotating base 110 and a winding roller 120 and a sampling roller 130 located on the rotating base 110. The rotating base 110 may include a rotating center 111, and the rotating base 110 may rotate about the rotating center 111.

[0054] Combination Figure 2 As shown, the winding roller 120 and the sampling roller 130 can both be rotatably connected to the rotating base 110, and the winding roller 120 and the sampling roller 130 can be circumferentially distributed around the rotation center 111. The rotating base 110 can be used to rotate the winding roller 120 to the winding position 105 when the copper foil 200 needs to be wound up, so that the winding roller 120 winds up the copper foil 200, and when the copper foil 200 needs to be sampled, the winding roller 120 is rotated away from the winding position 105, and the sampling roller 130 is located at the winding position 105, so that the sampling roller 130 winds up the copper foil 200.

[0055] For example, see Figure 2 As shown, the reeling position 105 may be a position close to the feeding position of the copper foil 200. When the copper foil 200 needs to be reeled, the rotating base 110 may rotate around the rotation center 111 and rotate the reeling roller 120 to the reeling position 105. At this time, the reeling roller 120 may be rotated to allow the copper foil 200 to be wound on the reeling roller 120. Figure 3As shown, after the winding roller 120 has finished winding, the rotating base 110 can be rotated again to turn the winding roller 120 away from the winding position 105, and rotate the sampling roller 130 to the winding position 105. At this time, by rotating the sampling roller 130, the copper foil 200 can be wound on the sampling roller 130, so that the sampling roller 130 can be sampled at the winding position 105.

[0056] The sampling roller 130 may be provided with a detection device 131, which may be used to detect the length of the copper foil 200 wound on the sampling roller 130. When the length of the copper foil 200 wound by the sampling roller 130 reaches the sampling requirement, the sampling may be stopped, thereby completing the sampling of the copper foil 200.

[0057] In the embodiment of the present application, the sampling roller 130 and the winding roller are rotatably arranged on the rotating base 110. The rotating base 110 can be rotated to switch the winding roller and the sampling roller 130 in turn at the winding position 105, so that the sampling roller 130 can sample the copper foil 200. Moreover, by arranging a detection device 131 for detecting the winding length of the copper foil 200 on the winding roller, the sampling length of the copper foil 200 of the sampling roller 130 can be accurately measured. In this way, the copper foil 200 can be accurately sampled without manual participation, which can effectively reduce human labor, reduce the difficulty of sampling the copper foil 200, and effectively improve the accuracy of sampling the copper foil 200.

[0058] Figure 4 A side view of a copper foil sampling device provided in an embodiment of the present application in a third state.

[0059] Among them, continue to see Figure 2 As shown, the number of the winding rollers 120 and the sampling rollers 130 can be two each, and the two winding rollers 120 and the two sampling rollers 130 can be staggered around the rotation center 111 of the rotating base 110 , and the two winding rollers 120 and the two sampling rollers 130 can be evenly arranged around the rotation center 111 .

[0060] For example, it can be understood that the central angle between the adjacent sampling roller 130 and the winding roller 120 is 90°. Figure 3 As shown, when the winding roller 120 is wound, the rotating base 110 can rotate 90° to turn the winding roller 120 away from the winding position 105 and rotate the sampling roller 130 to the winding position 105. Figure 4 As shown, after the sampling roller 130 completes sampling, the rotating base 110 can rotate another 90 degrees to turn the sampling roller 130 away from the winding position 105 and turn the winding roller 120 to the winding position 105. The copper foil 200 winding and sampling are performed alternately in this cycle.

[0061] Continue to see Figure 4 As shown, the copper foil sampling device 100 may further include a guide roller 150, which may be disposed adjacent to the winding position 105, and the guide roller 150 may be used to provide a guide function for the copper foil 200. For example, after the copper foil 200 is generated, it may be placed on the guide roller 150, so that the guide roller 150 may drive the copper foil 200 forward, thereby conveying the copper foil 200 to the winding position 105. For example, the number of the guide rollers 150 may be two, and the two guide rollers 150 may be disposed in parallel to convey the copper foil 200.

[0062] Continue to see Figure 4 As shown, the copper foil sampling device 100 may further include a cutter device 140, which may be disposed adjacent to the winding position 105. The cutter device 140 may be used to cut the copper foil 200 after the winding roller 120 completes winding of the copper foil 200, and to cut the copper foil 200 after the sampling roller 130 completes sampling of the copper foil 200.

[0063] For example, when the reel 120 completes the reeling of the copper foil 200, the reel 120 rotates away from the reeling position 105, and the sampling roller 130 rotates to the reeling position 105. At this time, the cutter device 140 can cut the copper foil 200 to disconnect the copper foil 200 from the reel 120, so that the copper foil 200 can start to be wound on the sampling roller 130. Correspondingly, when the sampling roller 130 completes the sampling of the copper foil 200, the sampling roller 130 rotates away from the reeling position 105, and the reel 120 rotates to the reeling position 105. At this time, the cutter device 140 can cut the copper foil 200 to disconnect the copper foil 200 from the sampling roller 130, so that the copper foil 200 can start to be wound on the reel 120.

[0064] For example, see Figure 4 As shown, the cutter device 140 may include a cutter body 141 and a cutter base 142. The cutter body 141 may be mounted on the cutter base 142, and the cutter body 141 may be extended or retracted relative to the cutter base 142. For example, when it is necessary to cut the copper foil 200, the cutter body 141 may be extended so that the cutter body 141 may cut the copper foil 200. When the cutter body 141 completes the cutting of the copper foil 200, the cutter body 141 may be retracted into the cutter base 142, so that the cutter base 142 may store the cutter body 141, so as to prevent the cutter body 141 from being exposed to the outside for a long time and causing accidental injury, which helps to improve the safety of the cutter device 140.

[0065] Among them, the extension and retraction method of the cutter body 141 in the cutter device 140 relative to the cutter base 142 can refer to the specific implementation method of the cutter pop-up and retraction device in the prior art, and the embodiment of the present application is not limited.

[0066] Continue to see Figure 4 As shown, in the present application, the interior of the sampling roller 130 may have a negative pressure chamber (not shown in the figure). For example, it can be understood that the sampling roller 130 is a hollow structure, and the sampling roller 130 may be provided with a plurality of through holes 132 (combined with Figure 1 As shown in FIG. 1 , the negative pressure chamber can be connected to the outside of the sampling roller 130 through the through hole 132. When the copper foil 200 is close to the surface of the sampling roller 130, the negative pressure chamber can adsorb the copper foil 200 on the surface of the sampling roller 130 through the through hole 132 to achieve the connection between the copper foil 200 and the sampling roller 130, so that the sampling roller 130 can wrap the copper foil 200 around the sampling roller 130 during the rotation process, thereby achieving the sampling of the copper foil 200.

[0067] For example, the copper foil sampling device 100 may include a negative pressure source (not shown in the figure), which may be connected to the negative pressure chamber. For example, the negative pressure source may be a motor, etc. The negative pressure source may draw air from the negative pressure chamber to generate negative pressure in the negative pressure chamber, so that the negative pressure chamber may adsorb the copper foil 200 onto the surface of the sampling roller 130 through the through hole 132.

[0068] The detection device 131 may be a rotation sensor, which may be located at one end of the sampling roller 130 and may be arranged away from the rotation center of the sampling roller 130. The rotation sensor may be used to detect the number of rotations of the sampling roller 130. In this way, the rotation angle of the sampling roller 130 may be obtained, and the rotation angle of the sampling roller 130 may be multiplied by the radius of the sampling roller 130 to obtain the length of the copper foil 200 wound on the sampling roller 130, thereby obtaining the sampling length of the copper foil 200.

[0069] Figure 5 A schematic diagram of control between a controller and a drive device provided in an embodiment of the present application.

[0070] See also Figure 5 As shown, the copper foil sampling device 100 may further include a first driving device 101, a second driving device 102, and a third driving device 103, wherein the first driving device 101 may be connected to the rotating base 110, and the first driving device 101 may be used to drive the rotating base 110 to rotate around the rotating center 111. For example, the first driving device 101 may be a driving motor, and the rotating center 111 may be connected to the output shaft of the driving motor, so that the output shaft of the driving motor can drive the rotating center 111 to rotate when rotating, thereby allowing the rotating base 110 to rotate.

[0071] The second driving device 102 may be connected to the winding roller 120, and the second driving device 102 may be used to drive the winding roller 120 to rotate relative to the rotating base 110. The third driving device 103 may be connected to the sampling roller 130, and the third driving device 103 may be used to drive the sampling roller 130 to rotate relative to the rotating base 110. For example, the second driving device 102 and the third driving device 103 may also be driving motors, and the winding roller 120 and the sampling roller 130 may be connected to the output shafts of the second driving device 102 and the third driving device 103, respectively, so that the second driving device 102 and the third driving device 103 may respectively drive the winding roller 120 and the sampling roller 130 to rotate on the rotating base 110.

[0072] The copper foil sampling device 100 may further include a controller 104, which may be signal-connected to the first driving device 101, the second driving device 102, the third driving device 103, and the detection device 131. The detection device 131 may transmit the length data of the copper foil 200 wound on the sampling roller 130 to the controller 104, and the controller 104 may be used to control the start or stop of the first driving device 101, the second driving device 102, and the third driving device 103 according to the sampling length.

[0073] For example, when sampling is required, the controller 104 can start the first driving device 101 to rotate to rotate the winding roller 120 to the winding position 105, and then start the second driving device 102 to rotate to rotate the winding roller 120, so that the copper foil 200 can be wound on the winding roller 120.

[0074] When the winding roller 120 has finished winding, the controller 104 can turn off the second driving device 102 to stop the winding roller 120 from rotating, and then start the first driving device 101 to rotate the winding roller 120 away from the winding position 105, and rotate the sampling roller 130 to the winding position 105. Then start the third driving device 103 to drive the sampling roller 130 to rotate, so that the copper foil 200 is wound on the sampling roller 130.

[0075] When the controller 104 receives the information from the detection device 131 that the sampling length reaches the sampling requirement, the controller 104 can stop the third driving device 103 to stop the sampling roller 130 from rotating to complete the sampling. At this time, the controller 104 rotates the first driving device 101 again to rotate the sampling roller 130 away from the winding position 105, and rotates the winding roller 120 to the winding position 105, and then performs the next cycle of winding operation.

[0076] The controller 104 can effectively realize the automation of copper foil 200 rolling and sampling, reduce or avoid the participation of staff, effectively reduce human labor, and improve the accuracy and efficiency of copper foil 200 rolling and sampling.
