[0017] The application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and are not limited to the utility model. In addition, it should be noted that, in order to facilitate the description, only the parts related to the utility model are shown in the drawings.

[0018] Please refer to the accompanying drawings Figs. 1-2 The embodiment of the application provides an aluminum electrolytic capacitor core package 140 roll deviation detection device, which is used for detecting the core package roll deviation product from the core package 140 to screen out the core package roll deviation product.

[0019] The aluminum electrolytic capacitor core package 140 roll deviation detection device comprises a bearing table 100, the bearing table 100 is provided with a detection station 101, the detection station 101 is provided with a metal detection assembly, and the metal detection assembly comprises a metal detector 110. The detection side of the metal detector 110 is provided with a bearing surface 111, here the detection side of the metal detector 110 refers to one side of the detection coil in the metal detector 110 in the circumferential axial direction, and the circumferential axial direction of the detection coil is the detection direction of the metal detector 110. The bearing surface 111 is used to bear the core package 140 in a set state, and the axial direction of the core package 140 in the set state is parallel to the detection direction of the metal detector 110. The metal detector 110 is used to detect the electrode foil in the core package 140, specifically: the metal detector 110 has a settable detection distance, the detection distance is set as D1 and D1=d1+d2, d1 is a distance threshold, and d2 is the distance between the detection surface of the metal detector 110 and the axial end surface close to the detection surface in the core package 140. When the electrode foil is detected in the detection magnetic field of the metal detector 110, it indicates that the edge distance between the electrolyte and the electrode foil of the current core package 140 is less than the distance threshold, that is, the current core package 140 is a core package roll deviation product. If the metal detector 110 does not detect the electrode foil, it indicates that the edge distance between the electrolyte and the electrode foil of the current core package 140 is above the distance threshold, that is, the current core package 140 is a qualified product. It should be understood that the above detection distance of the metal detector 110 should be understood as the maximum distance in the detection range in the detection direction.

[0020] In the embodiment, the metal detector 110 is used to detect the electrode foil in the core package 140, and the detection result can be used to judge whether the detected core package 140 is a core package roll deviation product. This not only realizes that the core package 140 does not need to be powered during the detection process of the core package roll deviation product, improves the detection efficiency of the core package roll deviation product, but also avoids the situation that the core package roll deviation product is missed, improves the detection accuracy of the core package roll deviation product, and reduces the safety hidden danger of the aluminum electrolytic capacitor.

[0021] Optionally, the set state is a vertical state or a horizontal state.

When the set state is the horizontal state, the set direction is the horizontal direction at this time, and one end of the core package 140 away from the tab connecting end contacts the detection surface of the metal detector 110.

[0022] In the set state of the vertical state, in order to simplify the structure, the end surface of the detection coil (i.e. the detection surface of the metal detector 110) can be used as the bearing surface 111, and at this time the metal detector 110 bears the core package 140 through the detection surface, i.e. d2 is 0. Of course, in other embodiments, the bearing plate can be provided on the bearing table 100, and the metal detector 110 is installed below the bearing plate.

[0024] Optionally, the prompter is at least one of a display, a sound prompter and a light prompter. Preferably, the prompter comprises a sound prompter and a light prompter, and the sound prompter and the light prompter are connected to the controller, so as to improve the prompting effect. The sound prompter can be a buzzer, and the light prompter can be a prompt light 120.

[0025] In some embodiments of the present application, the metal detection assembly further comprises a detection distance adjusting knob 130, and the detection distance adjusting knob 130 is connected to the controller. The detection distance adjusting knob 130 has a plurality of adjusting positions, and the controller is used to adjust the detection distance of the metal detector 110 according to the adjusting position of the detection distance adjusting knob 130. Through the above setting, the core package 140 with different distance thresholds can be detected without electricity, and the versatility of the core package 140 winding deviation detection device is improved.

[0026] Generally, the distance threshold can be 1.5-3mm. Optionally, the plurality of adjusting positions comprises at least three adjusting positions, and the three adjusting positions are respectively a first adjusting position with a detection distance of 1.5mm, a second adjusting position with a detection distance of 2.5mm and a first adjusting position with a detection distance of 3mm.

[0027] Optionally, the detection station 101 is a plurality of detection stations, and the plurality of detection stations 101 are arranged at intervals, so as to improve the detection efficiency of the core package 140 winding deviation detection device. Preferably, the plurality of detection stations 101 are arranged in a matrix.
