Description

Technical Field

[0001] The invention relates to the field of lithium ion battery production, and in particular to a lithium ion battery steel shell reversing mechanism. Background Art

[0002] Lithium-ion cylindrical batteries generally use metal steel shells because they have excellent strength and pressure resistance, and can effectively protect the internal structural parts of the battery from external impact. On the automated production equipment for lithium-ion cylindrical batteries, the shell openings of the steel shells that need to be fed need to be oriented in a consistent manner and supplied continuously, so a lithium-ion battery steel shell reversing mechanism is needed.

[0003] In the prior art, a push rod driven by a cam is set up to remove a portion of steel shells with inconsistent directions, and steel shells with consistent directions are retained. The turntable then drives the rotating part to rotate, and the steel shells pushed into the rotating part by the push rod are reversed. The lifting cylinder moves the rotating part downward until the reversed steel shells are placed on the conveyor belt. The reversing mechanism realizes the forward and reverse reversal of the rejected steel shells, thereby improving work efficiency.

[0004] Although the above technology can perform U-turn processing, it requires multiple rotations of a steel shell to adjust it to a uniform direction, which takes time and leads to low production efficiency. It is impossible to meet the demand for high-speed automation of the production line, so it has certain limitations in production efficiency. Summary of the invention

[0005] The present invention solves the problems of the prior art and provides a lithium ion battery steel shell reversing mechanism.

The steel shell pushed to one side enters the reversing turntable through the steel shell turntable. A shell lifting reversing guide plate is arranged above the reversing turntable. The shell lifting reversing guide plate lifts one side of the steel shell pushed to one side in the steel shell turntable station, and the steel shell body rotates along the shell lifting reversing guide plate as the reversing turntable finally realizes the reversal of the steel shell, and the steel shells with the same direction continuously flow into the discharging S-shaped material channel.

[0016] The shell-lifting reversing guide plate is arranged above the reversing turntable. The front section of the shell-lifting reversing guide plate lifts the shell opening side of the steel shell from the reversing turntable slot. The bottom of the steel shell is adsorbed by the magnet on the reversing turntable slot. As the reversing turntable rotates, the steel shell flips along the shell-lifting reversing guide plate to achieve U-turn and reversal. The end of the push rod in contact with the steel shell is provided with non-metallic material.

[0017] The steel shell on the slot of the steel shell turntable is transferred to the steel shell slot of the reversing turntable through the shell lifting and reversing guide plate.

The steel shell turntable 3 and the reversing turntable 8 are both provided with slots adapted to the size of the steel shell, the reversing turntable 8 is located on one side of the steel shell turntable 3, and the slots of the two correspond to each other, and a cam mechanism 4 is arranged on the other side of the steel shell turntable 3, the cam mechanism 4 includes a follower bearing 41 and a push rod 42 at the front end, the follower bearing 41 rotates along the cam track, and the position of the push rod 42 corresponds to the slot of the steel shell turntable 3 and is coaxially matched. A shell-lifting reversing guide plate 11 is arranged on the reversing turntable 8, the shell-lifting reversing guide plate 11 is at an acute angle to the horizontal plane, the shell-lifting reversing guide plate 11 is a right-angled trapezoid, and the right-angled side of the shell-lifting reversing guide plate 11 is fixed on the support plate 13. The bottom edge is located on one side of the reversing turntable 8, and the hypotenuse extends to the top of the reversing turntable 8. The number of the slots of the steel shell 10 on the steel shell turntable 3 is the same as the number of the push rods 42 on the cam mechanism 4 and corresponds one by one and concentrically.

[0030] The end of the push rod 42 in contact with the steel shell 10 is installed with non-metallic material.

[0031] A pulley 9 is provided on the same side of the steel shell turntable 3, the reversing turntable 8 and the cam mechanism 4. The pulleys 9 are connected to the drive motor 6 through a synchronous belt 7 to drive the pulley 9, so that the steel shell turntable 3, the reversing turntable 8 and the cam mechanism 4 rotate synchronously.

[0032] A support plate 13 is provided on the bottom plate of the machine body 1, and the axis of the pulley 9 and the shell reversing guide plate 11 are fixed on the support plate 13.

[0035] Through the sorting action of the cam push rod 42, the incoming steel shells 10 are divided into two rows on the steel shell turntable 3, one row remains in position, and the other row is pushed to the reversing turntable 8 to wait for reversing.

[0036] like Figure 1 As shown, the feed S-shaped channel 2 is an S-shaped structure, and a vertical transition channel 21 is arranged below the feed S-shaped channel 2 to ensure that the incoming steel shells 10 continuously and stably enter the slots of the steel shell turntable 3 in sequence.
