[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0035] The copper foil formed by calendering has the advantages of high strength, high elongation, and good tensile effect. The copper foil formed by calendering needs to be tested for its surface integrity and tensile properties.

[0036] Copper foil needs to undergo continuous calendering, which has a large length span and a long processing time. Sampling inspection is usually carried out after the overall processing of the copper foil is completed to determine the elongation of the copper foil and realize the test of tensile strength.

[0037] In order to realize online detection of copper foil in processing, some detection equipment is installed with matching detection equipment on the outside of the copper foil rolling processing equipment. The edges of the copper foil are trimmed and tested through traction and cutting devices to determine whether the tensile strength of the copper foil meets the requirements and to realize accurate calculation of the elongation.

[0038] Traditional inspection equipment is usually arranged on the outside of copper foil processing equipment. In order to achieve continuous cutting and inspection, the corresponding structure needs to be specially designed, which is large in size and requires reserved dedicated inspection space. At the same time, the area inspected by traditional inspection equipment is usually the edge of the copper foil, and the inspection position is limited to a single position, which affects the accuracy of the final inspection results.

[0039] In order to solve the above problems; refer to the attached Figure 1 -Attached Fig.10 A copper foil tensile strength and elongation detection device includes a detection mounting frame 100, a detection auxiliary device 300 is arranged in the middle of the detection mounting frame 100, guide components are installed on both sides of the detection auxiliary device 300, the detection auxiliary device 300 is rotatably connected to the detection mounting frame 100, and a detection channel for the copper foil 200 to pass through is formed between the detection auxiliary device 300 and the two guide components; the front end of the copper foil 200 moves in a directional manner during the traction process, and the copper foil 200 is guided by the detection auxiliary device 300 and the guide component to ensure that the copper foil 200 is in a taut state during the later sampling process, thereby ensuring the accuracy of the detection result.

[0040] Specifically, the circumferential side wall of the detection auxiliary device 300 includes a sampling surface 310 and a connecting surface 320. The sampling surface 310 is a flat surface. The surface of the sampling surface 310 is provided with a concave mounting opening 311. A retractable sampling device 400 is installed inside the mounting opening 311. When the sampling device 400 is not extended, it is hidden in the mounting opening 311 and will not affect the transportation and tensioning of the copper foil 200. During the rotation of the detection auxiliary device 300, when the copper foil 200 is laid flat on the surface of the sampling surface 310, the sampling device 400 extends to complete the sampling of the copper foil 200 to form the detection spline 210. Subsequently, the detection spline 210 is tightened and stretched manually or automatically to achieve accurate detection of the tensile strength and elongation of the detection spline 210.

[0041] The rotation radius of the detection auxiliary device 300 here is greater than the rotation radius of the guide assembly, so as to increase the contact area between the copper foil 200 and the detection auxiliary device 300, especially the sampling surface 310, and expand the sampling area of ​​the sampling device 400 by increasing the contact area to meet the needs of subsequent tensile strength clamping detection.

[0042] By setting a flat sampling surface 310, the copper foil 200 is in a flat and taut state, allowing the sampling device 400 to extend to cut the predetermined position of the copper foil 200, thereby achieving accurate and stable cutting and sampling; at the same time, the connecting surface 320 here is an arc, and its surface is located on the same virtual circle, which can guide the normally transported copper foil 200, ensure the stability of the copper foil 200 during the transportation process, and ensure the taut state of the copper foil 200 for continuous transportation.

[0043] Please refer to the attached Figure 8 -Attached Fig.10 The sampling surface 310 and the connecting surface 320 here can be selected in a variety of styles, and a single arc surface and a single plane combination can be selected, and N arc surfaces and N planes can also be selected. Any combination; the surface size and deflection angle of the sampling surface 310 can be adaptively adjusted as needed to meet the requirements of detection sampling.

[0044] In summary, through the above-mentioned structural design, the copper foil 200 can be cut and sampled for inspection during the production and transportation of the copper foil 200. The structural design of the detection auxiliary device 300 and the sampling device 400 can be located on the conveying path of the copper foil 200 and will not occupy the production space of the copper foil 200. At the same time, the state of cutting and sampling can be adjusted according to the area to be inspected, and the middle area of ​​the copper foil 200 can be inspected to meet the needs of accurate and efficient inspection.

[0045] It should also be noted here that, for the special-shaped detection auxiliary device 300, in order to ensure that the copper foil 200 is in a taut state, when the sampling surface 310 rotates to one side of the copper foil 200, the rotation speed of the detection auxiliary device 300 can be increased to achieve the tightening of the copper foil 200; at the same time, an elastic tightening guide roller can be installed on the outside of the detection auxiliary device 300 to achieve the tightening of the excess part of the copper foil 200 during the transportation process, to ensure that the copper foil 200 is continuously conveyed in a taut state, and at the same time to ensure the stability of the sampling device 400 in cutting and sampling the copper foil 200.

[0046] Specifically, the guide assembly includes a first guide roller 110 and a second guide roller 120, and the first guide roller 110 and the second guide roller 120 are selected as automatic power rollers, which can guide the copper foil 200 while conveying it; the detection auxiliary device 300 is located above the first guide roller 110 and the second guide roller 120, and the copper foil 200 passes through the upper surface of the first guide roller 110, the lower surface of the detection auxiliary device 300 and the upper surface of the second guide roller 120 in sequence, and the copper foil 200 forms a V-shaped conveying state between the first guide roller 110, the second guide roller 120 and the detection auxiliary device 300. Through the above arrangement, the sampling surface 310 rotates to the bottom and then cuts and samples the copper foil 200. The detection spline 210 after cutting and sampling can fall to the bottom position, and the sampling method of the top will not affect the normal conveying of the copper foil 200; without designing a manipulator for grasping, the detection spline 210 can automatically fall to a predetermined position under the action of gravity to achieve automatic sampling and collection.

[0047] Specifically, the preferred sampling device 400 includes a sampling component 430, and the sampling component 430 includes a sampling box 431. The upper end surface of the sampling box 431 is provided with a first negative pressure component 432, and the first negative pressure component 432 can be used to perform negative pressure suction on the area of ​​the copper foil 200 that needs to be sampled to ensure the stability of the copper foil 200 during the subsequent sampling and cutting process; a liftable sampling plate 433 is slidably connected to the inner wall of the sampling box 431, and a sampling tool 434 with a closed cutting surface is fixed to the upper end of the sampling plate 433. After the sampling tool 434 is extended, a predetermined area on the surface of the copper foil 200 can be cut to sample and form a detection spline 210; the projected area sampled by the sampling tool 434 here is smaller than the negative pressure suction area of ​​the first negative pressure component 432 to ensure the stability of the detection spline 210 during the cutting process and avoid affecting the copper foil 200 outside the sampling area.

[0048] The first negative pressure component 432 and the sampling tool 434 here are preferably rectangular strips, so as to facilitate the subsequent stretching test of the test spline 210; the above-mentioned sampling method is simple and efficient, and the cutting sampling can be completed by controlling the extended state of the sampling tool 434; by controlling the negative pressure absorption state of the first negative pressure component 432, the fixation before cutting and the subsequent rapid unloading of the test spline 210 can be completed, the overall sampling time is short, the sampling is efficient, and it is suitable for the detection auxiliary device 300 to perform cutting sampling during the continuous transportation of the copper foil 200.

[0049] Furthermore, the sampling device 400 also includes a rotatable rotating disk 410, and an electric guide rail 420 for controlling the linear movement of the sampling component 430 is fixed to the upper end of the rotating disk 410. The sampling component 430 can be controlled to be in different positions on the straight line through the electric guide rail 420, and the deflection angle of the sampling component 430 can be controlled through the rotating disk 410. The sampling component 430 can be controlled to be in different positions in the installation opening 311 through the cooperation of the rotating disk 410 and the electric guide rail 420, thereby satisfying the adaptability detection of different predetermined sampling areas. By performing position control adjustment through the above-mentioned device, it can be well hidden in the installation opening 311, meeting the demand for small-volume position control adjustment.

[0050] In order to support the copper foil 200 and further ensure the stability of the copper foil 200 during the cutting and sampling process, a supporting device 500 is also installed on the inner wall of the detection mounting frame 100. The supporting device 500 includes a deflection joint 510 arranged coaxially with the detection auxiliary device 300. The deflection joint 510 is retractable, and a supporting component 520 is fixed to the retractable end of the deflection joint 510. The supporting component 520 is controlled to fit with the sampling surface 310 and deflect synchronously by a predetermined angle to support the copper foil 200 from the outside. The deflection joint 510 can control the supporting component 520 to fit with the sampling surface 310 and deflect synchronously by a predetermined angle. 20 As the detection auxiliary device 300 coaxially deflects a predetermined angle, the deflection joint 510 is controlled to contract, so that the supporting component 520 can fit the sampling surface 310 from the outside. At this time, both sides of the copper foil 200 are in a tight state. The supporting component 520 is hollow, and the sampling tool 434 of the sampling component 430 can cut the copper foil 200 in a predetermined area after extending to form a detection spline 210; the supporting component 520 can play a role of bearing support on the outside, further ensuring the stability of the copper foil 200 during the cutting and sampling process.

[0051] It should be noted here that controlling the detection auxiliary device 300 to rotate at a slower linear speed can extend the time that the supporting component 520 is in contact with the sampling surface 310. When the supporting component 520 is rotated to the rear end limit position, the supporting component 520 is extended through the deflection joint 510, and the supporting component 520 is controlled to be staggered with the copper foil 200 to avoid affecting the normal transportation of the copper foil 200.

[0052] Furthermore, an elongation detection component 700 is installed at the bottom of the supporting component 520, and a transfer device 600 is also provided on the inner wall of the supporting component 520. The transfer device 600 transfers the detection spline 210 to one side of the elongation detection component 700 to complete automatic detection. The elongation detection component 700 can realize automatic detection of the tensile strength of the detection spline 210, so as to improve the efficiency of detection, realize real-time detection, and feed back the detection result to the production equipment of the copper foil 200 to adjust the rolling production parameters of the copper foil 200; at the same time, the transfer device 600 plays a role in transferring the detection spline 210 at the middle position, so that the detection splines 210 sampled at different positions can be transported to the elongation detection component 700 at a constant position to ensure the normal and rapid detection; further improving the efficiency of the automatic detection of the detection spline 210.

[0053] Specifically, the elongation detection component 700 includes two groups of symmetrically arranged detection ends 710, and the detection end 710 includes a clamping end 713, a first sliding joint 712 for controlling the clamping end 713 to move in a first direction, and a second sliding joint 711 for controlling the clamping end 713 to move in a second direction. The two clamping ends 713 can clamp the two ends of the detection spline 210 to prepare for tensile strength and elongation detection. The first sliding joint 712 can change the distance between the two clamping ends 713, control the two clamping ends 713 to move away from each other, and realize tensile detection of the detection spline 210.

[0054] It should be noted here that the second sliding joint 711 here can control the clamping end 713 and the first sliding joint 712 to move along the length direction of the supporting component 520, so that the clamping end 713 is staggered with the flipping position of the transfer device 600, ensuring the normal flipping of the overall structure of the transfer device 600 and ensuring the normal progress of the detection and transfer.

[0055] Specifically, the transfer device 600 includes a positioning platform 610, and the positioning platform 610 is rotatably connected to the supporting component 520 through a positioning shaft 611, and the axial direction of the positioning shaft 611 is consistent with the length direction of the supporting component 520; transfer components 620 are installed on both sides of the positioning platform 610, and the positioning platform 610 is controlled to rotate to complete the continuous transfer of the detection spline 210. The positioning shaft 611 is controlled by an electronic control device to drive the positioning platform 610 to rotate, so that the two groups of transfer components 620 can be respectively located on the side facing the sampling surface 310 to realize the grabbing of the detection spline 210, and the two groups of transfer components 620 are controlled to face the side of the elongation detection component 700 to realize the automatic transfer and placement of the detection spline 210; through the arrangement of the two groups of transfer components 620, the detection spline 210 that is continuously cut and sampled can be continuously grabbed, and the grabbed detection spline 210 can be placed between the elongation detection components 700, meeting the needs of continuous detection, especially suitable for high-speed detection scenarios.

[0056] Specifically, the transport component 620 includes a transport box 622 adapted to the sampling box 431. The sizes of the sampling box 431 and the transport box 622 are adapted to each other, so that the copper foil 200 can be accurately pressed and grasped. A retractable negative pressure transport terminal 623 is provided on the inner wall of the transport box 622, and a position control joint 621 for controlling the movement of the transport box 622 is also provided. After the transport box 622 has grasped the test spline 210 (the upper end of the transport box 622 can also be provided with a second negative pressure component similar to the first negative pressure component), the transport box 622 can be moved to the transport box 622, and the transport box 622 can be moved to the transport box 622. The pressure component performs negative pressure grabbing on the detection spline 210), and the negative pressure transfer end 623 extends out to relay grab the detection spline 210, so that the detection spline 210 can be located between the two detection ends 710 to achieve tensile testing; the position control joint 621 here can also be formed by a combination of a rotating structure and a linear drive structure to control the transfer box 622 to be in different positions, so that the transfer box 622 can be opposite to the sampling box 431, thereby achieving precise tightening of the detection spline 210 and accurate negative pressure grabbing.

[0057] It should also be noted that the negative pressure transfer terminal 623 here includes a telescopic element 6231 and a negative pressure plate 6232. The telescopic element 6231 can push the negative pressure plate 6232 to move upward to achieve negative pressure grasping of the detection spline 210. The size of the negative pressure plate 6232 here is smaller than the size of the upper end surface of the transfer box 622. In the process of negative pressure grasping of the detection spline 210 by the negative pressure transfer terminal 623, a gap of a predetermined length can be reserved on both sides of the detection spline 210 to facilitate the clamping end 713 to stably clamp the detection spline 210.

[0058] The present invention is further described below in conjunction with the detection method.

[0059] A method for detecting the tensile strength and elongation of copper foil, using the above-mentioned copper foil tensile strength and elongation detection device, comprises the following steps:

[0060] S1. Control the directional movement of the copper foil 200 between the guide assembly and the auxiliary detection device 300. In order to ensure that the copper foil 200 is in a taut state, when the sampling surface 310 rotates to one side of the copper foil 200, the rotation speed of the auxiliary detection device 300 can be increased to achieve the tightening of the copper foil 200. At the same time, an elastic tightening guide roller can be installed on the outer side of the auxiliary detection device 300 to tighten the excess part of the copper foil 200 during the transportation process, ensure that the copper foil 200 is continuously conveyed in a taut state, and at the same time ensure the stability of the sampling device 400 in cutting and sampling the copper foil 200.

[0061] S2. Control the auxiliary detection device 300 to rotate at a predetermined speed so that the copper foil 200 is laid flat on the surface of the sampling surface 310; that is, the copper foil 200 can be in a taut state on the surface of the sampling surface 310, so that the sampling device 400 can be extended to efficiently and stably cut and sample the copper foil 200, thereby avoiding the phenomenon of inaccurate sampling size affecting the production of the copper foil 200.

[0062] S3, control the sampling device 400 to extend to complete the sampling of the copper foil 200 to form the detection sample strip 210, and then manually or automatically detect the detection sample strip 210, so as to determine the tensile strength and elongation of the copper foil 200, so as to adjust the calendering production equipment of the copper foil 200 in real time, so as to keep the copper foil 200 in a stable production process and ensure the quality of the finished copper foil 200.

[0063] This solution allows cutting and sampling at various locations on the surface of the copper foil 200, and the detection result is more accurate; at the same time, the overall detection equipment is located on the conveying path of the copper foil 200, occupies a small volume, and the operation and control process is simple.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
