Problems solved by technology

There are many methods to realize the circumferential positioning of the battery sealing body, but most of the current positioning methods are not high in accuracy, resulting in uneven positions of the battery sealing body after the battery is circumferentially positioned, and it is impossible to realize the purpose of the battery sealing body being arranged in one direction.
Sometimes manual correction or even manual positioning is required, resulting in low integration of equipment automation and low production efficiency

Embodiment 1

[0023] Embodiment 1: A circumferential positioning device for a cylindrical battery sealing body, including a control circuit, a feeding motor 1 and a driving device, the driving device drives the cylindrical battery body 5 to rotate, the control circuit is connected to the feeding motor 1, The servo motor 1 is connected with the driving device, and also includes two sets of through-beam sensors, respectively the first through-beam sensor 7 and the second through-beam sensor 8, and the first through-beam sensor 7 and the second through-beam sensor 8 On the same plane, the ray interaction point of the first through-beam sensor 7 and the second through-beam sensor 8 is on the same horizontal line as the center position of the sealing body of the cylindrical battery, and the distance between the ray interaction point and the rotation center of the cylindrical battery body is O is e, the vertical distance between the center of rotation O of the cylindrical battery body and the inne...

Embodiment 2

[0029] Embodiment 2: other parts are the same as Embodiment 1, the difference is that the angle between the ray A-A1 of the first through-beam sensor 7 and the ray B-B1 of the second through-beam sensor 8 is 20 degrees.

Embodiment 3

[0030] Embodiment 3: other parts are the same as Embodiment 1, the difference is that the angle between the ray A-A1 of the first through-beam sensor 7 and the ray B-B1 of the second through-beam sensor 8 is 25 degrees.

[0031] When the circumferential positioning signal starts, the servo motor 1 starts to rotate, driving the synchronous belt 3 and the driving pressure wheel 4 to rotate. The cylindrical battery body 5 starts to rotate under the joint action of the driving pinch wheel 4 , the first driven pinch wheel 6 and the second driven pinch wheel 9 . The position of the battery sealing body is constantly changing, and the occlusion of the first on-shooting sensor 7 and the second on-shooting sensor 8 is also constantly changing, such as figure 2 , image 3 , Figure 4 shown.

[0032] When the sealing body position is rotated to Figure 5At the position shown, the first through-beam sensor 7 is blocked, and the second through-beam sensor 8 has just been blocked, ...

Abstract

The invention discloses a circumferential positioner for a seal body of a cylindrical cell. The circumferential positioner provided by the invention comprises a control circuit, a servo motor and a drive unit, wherein the control circuit is connected with the servo motor which is connected with the drive unit. The circumferential positioner also comprises two opposite inductors, which are respectively a first opposite inductor and a second opposite inductor. The first opposite inductor and the second opposite inductor are disposed in the same plane; a radial interaction point of the first opposite inductor with the second opposite inductor is arranged on the same level as the central position of the cylindrical cell's seal body; the distance from the radial interaction point to a rotationcenter of the cylindrical cell body is e; the vertical distance from the rotation center of the cylindrical cell body to the inner wall of the seal body is d; and the vertical distance from the rotation center of the cylindrical cell body to the outer wall of the seal body is D, wherein the eccentric distance e satisfies the following condition: d<e<D. The invention has the following advantage: by circumferential positioning, cells' seal bodies are arrayed orderly in the same direction.

Description

technical field [0001] The invention relates to a positioning device in the battery assembly process, in particular to a circumferential positioning device for a cylindrical battery sealing body. Background technique [0002] Cylindrical batteries generally include components such as crimps, seals, and steel shells. The crimped product is assembled in a steel shell, and the sealing body is generally welded to the crimped product through tabs. In the assembly line production process of cylindrical batteries, before the liquid filling and battery sealing processes, the disorderly discharged batteries need to be positioned in the circumferential direction, so as to realize the orderly arrangement of the battery sealing bodies in the same direction. There are many methods to realize the circumferential positioning of the battery sealing body, but most of the current positioning methods are not high in accuracy, resulting in uneven positions of the battery sealing body after the...
