[0025] The technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0026] Embodiment 1

[0027] As Figure 1-3 shown, the detection device includes a handheld part 1. A filter paper 2 is arranged at the top of the handheld part 1, and a collar 3 for fixing the filter paper 2 is arranged on the periphery of the handheld part 1. The bottom of the handheld part 1 is a cylindrical structure 4. A semi-cone 5 is fixedly arranged at the top of the cylindrical structure 4. The bottom diameter of the cylindrical structure 4 is the same as the bottom diameter of the semi-cone 5. The inner diameter of the collar 3 gradually increases from top to bottom. The inner diameter of the top of the collar 3 is slightly larger than the top diameter of the semi-cone 5, so that the collar 3 can be sleeved on the semi-cone. The diameter of the circular filter paper 2 is larger than the top diameter of the semi-cone 5, which facilitates the collar 3 to fix the filter paper 2.

[0028] During use, take a piece of filter paper 2, cover one end of the solid steel semi-cone 5, then use the collar 3 to clamp the filter paper 2 and fix it on the solid steel. Then use a spray bottle to spray alcohol to wet the filter paper 2, and drag the solid steel with the filter paper 2 at one end by hand to move left and right in the rolling direction of the foil (note to keep stable, apply force in the left and right directions, and do not apply external force in the vertical direction, and strictly prohibit scratching the surface). The wiping position is at the left rib, middle, and right rib of the strip. The wiping length is 400*400mm, and the wiping times are 10 times (5 back and forth). After wiping, the aluminum ash will be rated according to the amount of aluminum ash on the filter paper 2, which is divided into good, slight, moderate, and severe.

[0029] For easy observation, the filter paper 2 in this application uses white filter paper 2 with a weight of 80 - 120 g / m 2 and a diameter of about 100 - 120 mm.

[0030] In this application, the height of the collar 3 can be 20 mm, the inner diameter of the bottom of the collar 3 is 60 mm, the inner diameter of the top of the collar 3 is 58 mm, and the outer diameter of the collar 3 is 70 mm. The bottom diameter of the columnar structure is 60 mm, its height is 18 mm, the bottom diameter of the semi-cone 5 is 60 mm, the top diameter is 56 mm, and the height of the semi-cone 5 is 52 mm.

[0031] Embodiment 2

[0032] As Figure 1-7 shown, in addition to the structure of Embodiment 1, the detection device of the present application further includes a workbench 6. A gantry 7 is arranged on the workbench 6. One side of the top plate of the gantry 7 is provided with a first motor placement shell 8. The output end of the first motor passes through the first motor placement shell 8 and is connected to a threaded rod 9. The threaded rod 9 passes through a first through groove 10 provided on the top plate. A first slider 11 is threadedly arranged on the threaded rod 9. A cylinder fixing shell 12 is arranged at the bottom of the first slider 11. The bottom of the output end of the cylinder is connected to a connecting plate 13. One side of the connecting plate 13 is provided with a second motor placement shell 14. The output end of the second motor passes through the second motor placement shell 14 and is connected to a bidirectional threaded rod 16. The bidirectional threaded rod 16 passes through a second through groove 15 arranged inside the connecting plate 13. The thread directions on both sides of the bidirectional threaded rod 16 are opposite. Second sliders 17 are arranged along both sides of the cylinder fixing shell 12 on the bidirectional threaded rod 16. Symmetric arc-shaped clamping plates 18 are respectively arranged at the bottoms of the second sliders 17. In order to increase the friction force, an anti-slip layer is arranged on the arc-shaped clamping plates 18. The width of the first slider 11 is the same as that of the first through groove 10, and the width of the second slider 17 is the same as that of the second through groove 15, which facilitates the sliding of the two sliders.

[0033] A control member 19 is arranged on the workbench 6. The control member 19 is electrically connected to the first motor, the second motor, and the cylinder. The control member 19 includes a display screen and control buttons. During operation, by pressing the control buttons, first drive the second motor to drive the bidirectional threaded rod 16 to rotate, then drive the second slider 17 and the arc-shaped clamping plate 18 to move, clamp the inverted handheld member 1, then drive the cylinder to move the handheld member 1 to a suitable position, and finally drive the first motor to drive the threaded rod 9 to rotate, then drive the first slider 11, the cylinder fixing shell 12, the connecting plate 13, and the arc-shaped clamping plate 18 to reciprocate and move, dragging the solid steel body with one end of the filter paper 2 to move left and right in the rolling direction of the foil.

[0034] Therefore, the present application provides a detection device for aluminum ash on the surface of aluminum foil for batteries, which solves the abnormal situation that the aluminum ash on the surface of the foil cannot be detected in the cold rolling and foil rolling processes of the prior art.
