[0031] Techniques, methods, and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be regarded as part of the specification.

[0032] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0033] As Figure 1 shown, the aluminum foil folding and pressing device of the present disclosure includes an aluminum foil clamping mechanism and an aluminum foil folding and pressing driving mechanism.

[0034] The aluminum foil clamping mechanism includes a linkage assembly, an upper clamping assembly, and a lower clamping assembly. The linkage assembly includes a left linkage member 1 and a right linkage member 2. The left linkage member 1 and the right linkage member 2 are disposed opposite to each other. The left linkage member 1 and the right linkage member 2 may have a block structure or a frame structure.

[0035] The upper clamping assembly includes an upper left clamping plate 3 and an upper right clamping plate 4. The upper left clamping plate 3 and the upper right clamping plate 4 are rotatably connected, and the upper left clamping plate 3 is rotatably connected to the left linkage member 1, and the upper right clamping plate 4 is rotatably connected to the right linkage member 2. The above-mentioned rotational connection can be achieved by means such as pivot connection or ball-and-socket connection. In this way, the upper left clamping plate 3 and the upper right clamping plate 4 can rotate relative to each other under the drive of the left linkage member 1 and the right linkage member 2 to achieve bending.

[0036] The lower clamping assembly includes a lower left clamping plate 5 and a lower right clamping plate 6. The lower left clamping plate 5 and the lower right clamping plate 6 are rotatably connected, and the lower left clamping plate 5 is rotatably connected to the left linkage member 1, and the lower right clamping plate 6 is rotatably connected to the right linkage member 2. The above-mentioned rotational connection can be achieved by means such as pivot connection or ball-and-socket connection. In this way, the lower left clamping plate 5 and the lower right clamping plate 6 can rotate relative to each other under the drive of the left linkage member 1 and the right linkage member 2 to achieve bending.

[0037] An aluminum foil clamping gap 7 is provided between the upper clamping assembly and the lower clamping assembly. The aluminum foil can be placed in the aluminum foil clamping gap 7 and be folded and pressed along with the bending actions of the upper clamping assembly and the lower clamping assembly.

[0038] The aluminum foil folding drive mechanism includes a rod assembly and a drive unit 10. The rod assembly includes a left rod 8 and a right rod 9. The left rod 8 is rotatably connected to the left link 1, and the right rod 9 is rotatably connected to the right link 2. The above-mentioned rotational connection can be achieved by a pivot connection or a ball-and-socket connection. The drive unit 10 is rotatably connected to the left rod 8 and the right rod 9, and the drive unit 10 can be used to drive the left rod 8 and the right rod 9 to move in a direction close to or away from the aluminum foil clamping mechanism. The drive unit 10 can be, for example, a cylinder. The left rod 8 and the right rod 9 are driven to move by the drive unit 10, and the left link 1 and the right link 1 move synchronously with the left rod 8 and the right rod 9. The left link 1 and the right link 1 drive the upper clamping assembly and the lower clamping assembly to bend repeatedly, and the aluminum foil placed in the aluminum foil clamping gap 7 is repeatedly folded and pressed along with the bending action of the upper clamping assembly and the lower clamping assembly.

[0039] In a specific implementation, the number of folding and pressing actions can be controlled by controlling the movement of the driving unit 10 .

[0040] The aluminum foil folding device disclosed in the present invention can clamp the aluminum foil to be tested through the aluminum foil clamping mechanism, and the aluminum foil folding driving mechanism can drive the aluminum foil clamping mechanism to perform repeated folding actions, so that the aluminum foil to be tested can be repeatedly folded and pressed, thereby effectively improving the efficiency and accuracy of aluminum foil coating fastness testing.

[0041] In one embodiment of the aluminum foil folding device disclosed in the present invention, the upper left clamping plate 3 and the upper right clamping plate 4 are rotatably connected via the upper rotating shaft 11, and the lower left clamping plate 5 and the lower right clamping plate 6 are rotatably connected via the lower rotating shaft 12. The upper rotating shaft 11 and the lower rotating shaft 12 are arranged opposite to each other, and the upper rotating shaft 11 and the lower rotating shaft 12 are parallel. The aluminum foil clamping mechanism of this structure has good action accuracy and repeatability, and can improve the precise positioning of the aluminum foil folding position.

[0042] In one embodiment of the aluminum foil folding device disclosed in the present invention, a left clamping groove 100 is provided on the left linking member 1, and a right clamping groove 200 is provided on the right linking member 2. The aluminum foil clamping gap 7 is connected to the left clamping groove 100 and the right clamping groove 200. In this way, the two ends of the aluminum foil to be tested can be located in the left clamping groove 100 and the right clamping groove 200, respectively, thereby effectively improving the stability and uniformity of the force applied to the aluminum foil during the folding process.

[0043] During specific implementation, the upper left clamping plate 3 and the lower left clamping plate 5 can be rotatably connected to the edge of the opening of the left clamping groove 100, and the upper right clamping plate 4 and the lower right clamping plate 6 can be rotatably connected to the edge of the opening of the right clamping groove 200, so as to more reliably confine the aluminum foil within the aluminum foil clamping gap 7.

[0044] Further, the aluminum foil clamping mechanism further includes an auxiliary clamping assembly. The auxiliary clamping assembly includes an auxiliary clamping member 13 and an auxiliary clamping member driving unit 14.

[0045] An auxiliary clamping member chute is provided on the left linkage member 1 and / or the right linkage member 2. The auxiliary clamping member chute communicates with the left clamping groove 100 and / or the right clamping groove 200, and the auxiliary clamping member 13 is slidably engaged with the auxiliary clamping member chute. The auxiliary clamping member driving unit 14 can be used to drive the auxiliary clamping member 13 to move along the auxiliary clamping member chute so that the auxiliary clamping member 13 presses or releases the aluminum foil in the left clamping groove 100 and / or the right clamping groove 200. The auxiliary clamping member driving unit 14 can be, for example, a cylinder or a motor. The auxiliary clamping member 13 can have a block structure.

[0046] The provision of the auxiliary clamping assembly is conducive to more stably pressing the end of the aluminum foil in the left clamping groove 100 and / or the right clamping groove 200 during the process of folding and pressing the aluminum foil. Those skilled in the art can choose to press one end or both ends of the aluminum foil in the clamping grooves of each linkage member according to actual needs.

[0047] Specifically, the end face of the auxiliary clamping member 13 in contact with the aluminum foil can also be made of a material with a relatively large coefficient of friction such as silica gel or rubber to more stably and reliably press the end of the aluminum foil in the left clamping groove 100 and / or the right clamping groove 200.

[0048] Furthermore, auxiliary clamping assemblies are provided on both the left linkage member 1 and the right linkage member 2.

[0049] In an embodiment of the aluminum foil folding and pressing device of the present disclosure, the pull rod assembly further includes a connecting block 15 and a sliding support member 16. Both the left pull rod 8 and the right pull rod 9 are rotatably connected to the connecting block 15, and the above-mentioned rotational connection can be achieved by means such as pivot connection or ball socket connection. The connecting block 15 and the sliding support member 16 are slidably connected. By moving the connecting block 15 along the sliding support member 16 to drive the left pull rod 8 and the right pull rod 9 to move, the stability of the movement of the left linkage member 1 and the right linkage member 2 can be improved.

[0050] Specifically, the sliding support member 16 can have a rod-like structure and maintain its position unchanged by being fixedly connected to the bracket.

[0051] Further, the left pull rod 8 and the right pull rod 9 are connected to the connecting block 15 through the same rotating shaft. That is, the left pull rod 8 and the right pull rod 9 share a rotating shaft, thereby improving the consistency of the movement of the left linkage member 1 and the right linkage member 2.

[0052] Further, the pull rod assembly further includes a connecting arm 17. The driving unit 10 is a rotating wheel disc, and both ends of the connecting arm 17 are rotatably connected to the rotating wheel disc and the connecting block 15 respectively. The arrangement of the rotating wheel disc is beneficial to maintaining the consistency of the repeated folding and pressing actions, thereby improving the accuracy of detection.

[0053] In an embodiment of the aluminum foil folding and pressing device of the present disclosure, the aluminum foil folding and pressing driving mechanism further includes a sliding rod 18. The left linkage 1 and the right linkage 2 are slidably matched with the sliding rod 18. During the process of the left pull rod 9 and the right pull rod 9 driving the left linkage 1 and the right linkage 2 to move, the left linkage 1 and the right linkage 2 move along the sliding rod 18, so that the movement of the left linkage 1 and the right linkage 2 is restricted by the sliding rod 18, which can effectively improve the stability of the folding and pressing movement.

[0054] In an embodiment of the aluminum foil folding and pressing device of the present disclosure, the aluminum foil folding and pressing driving mechanism further includes a top driving assembly. The top driving assembly and the pull rod assembly are respectively located on both sides of the aluminum foil clamping gap 7.

[0055] The top driving assembly includes a top driving member 19 and a top driving member driving unit 20. The top driving member driving unit 20 can be used to drive the top driving member 19 to abut against the upper clamping assembly or the lower clamping assembly. The top driving member driving unit 20 can be, for example, a cylinder or an electromagnetic cylinder. The top driving assembly can be used to, when the upper clamping assembly or the lower clamping assembly moves to the limit position, apply a force in the direction towards the pull rod assembly to the upper clamping assembly or the lower clamping assembly by directly abutting, so that the clamping assembly can be quickly reset, achieving the effects of improving efficiency and ensuring safety.

[0056] Specifically, the pull rod assembly can be located on the side of the lower clamping assembly away from the upper clamping assembly, and the top driving assembly can be located on the side of the upper clamping assembly away from the lower clamping assembly. Through the cooperation of the pull rod assembly and the top driving assembly, the repeated folding and pressing of the aluminum foil is realized.

[0057] In addition, the top driving member 19 can have a rod-shaped structure and can be disposed opposite to the upper rotating shaft 11 or the lower rotating shaft 12.

[0058] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
