Embodiment Construction

[0014] Further description will be made below in conjunction with the accompanying drawings.

[0015] like figure 1 Shown is a device for detecting burrs on pole pieces according to an embodiment. The device includes a metal base 10 , an insulating pole piece seat 20 stacked on the metal base 10 and a movable metal upper cover 30 .

[0016] like figure 2 shown, is figure 1 The top view of the metal base with the pole piece seat in it. The part of the metal base 10 not covered by the pole piece seat 20 is the contact area 12 .

[0017] The pole piece seat 20 is an insulator. The thickness of the pole piece holder 20 is the same as the maximum tolerable burr height. The maximum tolerable burr height is the standard value of burr control. If the burr height of the pole piece exceeds this standard value, it is not suitable for battery production and is a substandard product.

[0018] The metal upper cover 30 is movable, and can be covered on or removed from the pole piece ...

Abstract

The invention relates to a device for detecting a pole piece burr, comprising a metal base, an insulating pole piece base and a moveable metal upper cover which are overlapped on the metal base, wherein the part on the metal base not covered by the pole piece base is a contact area; the thickness of the pole piece base is the same as the maximum tolerable burr height; a detection unit is connected between the metal base and the metal upper cover; the detection unit is used for detecting whether the metal base is connected with the metal upper cover. Furthermore, the invention relates to a method for detecting the pole piece burr. According to the device and the method, the insulating pole piece base with the thickness to be the same as the maximum tolerable burr height is arranged betweenthe metal upper cover and the metal base for judging whether the pole piece is valid during detection according to the condition whether the metal base is connected with the metal upper cover; and the method and the device are simple, convenient and high in efficiency.

Description

【Technical field】 [0001] The invention relates to battery detection, in particular to a device and method for measuring pole piece burrs. 【Background technique】 [0002] The burr on the edge of the battery pole piece can cause the internal short circuit of the battery and even cause serious consequences. Therefore, the detection of the height of the pole piece burr is very important. The traditional detection method: use a projector to obtain the image of the pole piece, and then measure the burr on the image The height of the burr is compared with the preset height to judge whether the height of the burr is within the tolerable range. [0003] This detection method is less efficient because of the long comparison time. 【Content of invention】 [0004] Based on this, it is necessary to provide a more efficient device for detecting burrs on pole pieces. [0005] A device for detecting pole piece burrs, comprising a metal base, an insulating pole piece seat stacked on the m...
