Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of full tab large cylindrical battery cell, and particularly relates to a full tab large cylindrical pre-welding machine battery cell correcting mechanism. BACKGROUND
[0002] At present, the current collecting plate of the battery cell is directly placed on the conveying device, and the deflection of the current collecting plate cover cannot be determined to avoid. If the deflection is adjusted manually, the machine needs to be stopped, which is not safe, wastes a lot of time, and is difficult to ensure the smoothness of production and reduce the production efficiency. SUMMARY
[0003] The present application aims at the defects and deficiencies of the prior art, and provides a full tab large cylindrical pre-welding machine battery cell correcting mechanism.
[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is:
[0005] The full tab large cylindrical pre-welding machine battery cell correcting mechanism comprises two symmetrical supports, and the inner side surfaces of the supports are each provided with at least one rotating wheel set.
[0006] The rotating wheel set is composed of two parallel rotating wheel assemblies, and each rotating wheel assembly is composed of a rotating shaft rotatably connected to the support and a rotating wheel fixed to the end of the rotating shaft.
[0007] The rotating wheel set on one of the supports is provided with a motor driving assembly, and the motor driving assembly comprises a belt, a driven wheel and a motor fixed to one end of the support.
[0008] One of the supports is provided with a first pushing-out assembly, and the other support is provided with a second pushing-out assembly.
[0009] Further, the first pushing-out assembly comprises a first cylinder fixed to one end of one of the supports and a pushing block fixed to the other end of the first cylinder, and the second pushing-out assembly comprises a second cylinder fixed to one end of the other support and a pressing head fixed to the other end of the second cylinder.
[0010] Further, the two rotating shafts of the same rotating wheel set are provided with a sensor support fixed to the support, and the sensor support is fixed with at least three sensors distributed in the circumferential direction.
[0011] Further, the sensor support is provided with a strip-shaped hole for clamping the sensor, and the sensor is fixed to the sensor support by two nuts.
[0012] Furthermore, the wheel has at least one rubber ring encased on its body.
[0013] With the above structure, the beneficial effects of this invention are as follows: In the battery cell alignment mechanism of the large cylindrical pre-welding machine with all tabs described in this invention, the battery cell is placed stably between two wheels on one side of the rotating wheel assembly, while the current collector is positioned above the two wheels on both sides of the rotating wheel assembly. The first ejection component and the second ejection component move in opposite directions until they are respectively positioned against both ends of the battery cell. Then, the first ejection component and the second ejection component release their clamping grip on the battery cell. The motor starts, driving the drive wheel, belt, and driven wheel to rotate the rotating wheel on the shaft. The friction between the rotating wheel and the surface of the battery cell causes the battery cell to rotate until the current collector faces the set requirements. This structure can align the current collector of the battery cell without direct human contact with the battery, and without stopping the machine, making the battery production process smoother and improving battery production efficiency.

[0022] The invention will now be further described with reference to the accompanying drawings.
[0023] like Figs. 1 to 4 As shown, the present invention provides a full-tab large cylindrical pre-welding machine cell correction mechanism, which includes two symmetrically arranged supports 1; each support 1 has at least one set of rotating wheels on its inner surface.
[0024] The wheel assembly consists of two parallel wheel assemblies; each wheel assembly consists of a rotating shaft 8 rotatably connected to the support 1 and a wheel 9 fixed to the end of the rotating shaft 8.
[0025] Each of the roller groups on one of the supports 1 is equipped with a motor drive assembly; the motor drive assembly includes a belt 4, a driven pulley 5, and a motor 3 fixed at one end to the support 1; the other end of the motor 3 is fixed to a drive pulley 2; the driven pulley 5 is fixed on one of the shafts 8 in the roller group; the belt 4 is tensioned on the drive pulley 2 and the driven pulley 5;
[0026] One of the supports 1 is provided with a first ejection component; the other support 1 is provided with a second ejection component;
[0027] Cell A is placed stably between two rollers 9 on one side of the roller assembly, while the current collector A1 is placed above the two rollers 9 on both sides of the roller assembly. The first ejection component and the second ejection component move in opposite directions until they are positioned against the two ends of cell A. Then, the first ejection component and the second ejection component release their grip on cell A. The motor 3 starts and drives the drive wheel 2, belt 4 and driven wheel 5 to rotate the rollers 9 on the shaft 8. The friction between the rollers 9 and the surface of cell A causes cell A to rotate until the current collector A1 is aligned to the set requirements. This structure can align the current collector A1 of cell A without direct human contact with the battery or the need to stop the machine, making the battery production process smoother and improving battery production efficiency.
[0028] In a preferred embodiment of the present invention, the first ejection assembly consists of a first cylinder 6 fixed at one end to one of the supports 1 and a push block 7 fixed at the other end of the first cylinder 6; the second ejection assembly consists of a second cylinder 11 fixed at one end to another support 1 and a pressure head 10 fixed at the other end of the second cylinder 11; after the battery cell A is placed on the rotating wheel 9, the push block 7 and the pressure head 10 are respectively on both sides of the battery cell A; the first cylinder 6 drives the push block 7 to move towards the battery cell A; the second cylinder 11 drives the pressure head 10 to move towards the battery cell A, and the push block 7 and the pressure head 10 are used to press against both ends of the battery cell A for positioning.
[0029] In a preferred embodiment of the present invention, a sensor bracket 12 fixed on a support 1 is provided between the two rotating shafts 8 of the same rotating wheel assembly; at least three sensors 13 distributed along the circumferential direction are fixed on the sensor bracket 12; the sensors are not fundamentally different from those in the prior art, so they will not be described in detail here; the three sensors 13 respectively detect three points on the upper edge of the current collector A1; the sensing points of the three sensors 13 form a triangle, which is the inscribed triangle of the current collector A1; when the current collector A1 does not completely block the three sensors 13 at the same time, the battery cell A needs to rotate an angle until the current collector A1 blocks the three sensors 13 at the same time.
[0030] In a preferred embodiment of the present invention, the sensor bracket 12 has a strip-shaped hole 1201 for clamping the sensor 13; each sensor 13 is threaded with two nuts; the sensor 13 passes through the strip-shaped hole 1201 and is clamped and fixed on the sensor bracket 12 by the two nuts; according to the diameter of the collector plate A1, the position of the sensor 13 on the sensor bracket 12 is adjusted by loosening the nuts, so that when the collector plate A1 is aligned, the three sensing points of the three sensors 13 form an inscribed triangle of the collector plate A1.
[0031] As a preferred embodiment of the present invention, at least one rubber ring 14 is fitted on the wheel body of the rotor 9; the rubber ring 14 is used to enhance the friction between the rotor 9 and the battery cell A.
[0032] When using this invention, the battery cell is placed stably between two wheels on one side of the rotating wheel assembly, while the current collector is placed above the two wheels on both sides of the rotating wheel assembly. The first cylinder drives the push block to move towards the battery cell; the second cylinder drives the pressure head to move towards the battery cell, using the push block and pressure head to press against both ends of the battery cell for positioning; three sensors detect three points on the upper edge of the current collector respectively. When it is detected that the current collector has not completely fallen into the three detection points, the motor starts and drives the drive wheel, belt and driven wheel to rotate the rotating wheel on the shaft. The friction between the rotating wheel and the surface of the battery cell causes the battery cell to rotate until it stops rotating when the current collector blocks the three sensors. This structure can align the current collector of the battery cell without direct human contact with the battery and without stopping the machine, making the battery production process smoother and improving battery production efficiency.
[0033] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
