Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing, specifically to a rubber stopper pressing mechanism. Background Technology

[0002] In the process of assembling lithium batteries, rubber plugs need to be fed into a disc so that the disc can rotate and the rubber plugs can pass through different stations to complete different processes. The existing rubber plug feeding method is to feed from the side of the disc, and does not realize feeding from the top of the disc. Moreover, the feeding accuracy of the existing method is not high, and the error is large for small rubber plugs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rubber stopper pressing mechanism that can feed rubber stoppers into a disc from above. The specific technical solution is as follows:

[0004] A rubber stopper pressing mechanism includes a fixed plate, a support base, a lifting block, a lifting power component, a pressure rod, a limiting plate, a spring, an opening and closing block, a connecting plate, a movable plate, and a rubber stopper block. The support base is installed above the fixed plate, and the lifting block is slidably installed in front of the support base. The lifting power component drives the lifting block to move up and down. The pressure rod is movably mounted inside the lifting block, and a limiting plate is installed around the pressure rod. A spring is mounted on the pressure rod. When the lifting block moves down, the spring drives the pressure rod to move down. The opening and closing block is fixedly connected below the pressure rod. A connecting plate is hinged to each of the left and right sides of the opening and closing block. The rubber stopper block is installed in front of the fixed plate and is located above a disc. The rubber stopper block has a discharge hole for a single rubber stopper to pass through. A movable plate is slidably installed on each of the left and right sides of the rubber stopper block. The left connecting plate is hinged to the left movable plate, and the right connecting plate is hinged to the right movable plate. The bottom end of the pressure rod extends directly above the discharge hole.

[0005] As a preferred embodiment of this utility model, when the opening and closing block moves upward, the two movable pieces move inward to block the discharge hole; when the opening and closing block moves downward, the two movable pieces move outward to open the discharge hole, and the pressure rod extends into the feed trough.

[0006] As a preferred embodiment of this utility model, the movable piece includes a baffle part and a hinge part connected together. The baffle part is located inside the rubber stopper block and is used to block the discharge hole. The hinge part is connected above the baffle part and extends out of the rubber stopper block. The hinge part is provided with a hinge hole. The hinge part is inserted into the hinge hole and the connecting piece through a hinge shaft to achieve hinge connection with the connecting piece.

[0007] As a preferred embodiment of this utility model, the discharge hole is vertically arranged, and the rubber stopper block is also provided with a horizontally arranged feed groove, which is connected to the discharge hole.

[0008] As a preferred embodiment of this utility model, a linear bearing is installed inside the lifting block, the upper part of the pressure rod passes through the linear bearing, the upper end of the spring abuts against the linear bearing and the lower end abuts against the limiting plate.

[0009] As a preferred embodiment of this utility model, a limit ring is fixedly installed above the pressure rod, and the outer diameter of the limit ring is larger than the inner hole of the lifting block.

[0010] As a preferred embodiment of this utility model, a slide rail is vertically installed in front of the support base, the slide rail is slidably connected to the slider, and the slider is fixedly installed on the lifting block.

[0011] As a preferred embodiment of this utility model, the pressure rod and the opening / closing block are interference-fitted.

[0012] As a preferred embodiment of this utility model, the lifting power component is a pneumatic cylinder, a hydraulic cylinder, a servo electric cylinder, or a cam swing arm mechanism.

[0013] Beneficial effects: The rubber stopper pressing mechanism of this utility model has a novel design. Under normal conditions, the two movable plates block the discharge hole to ensure that the rubber stopper will not fall out. When the lifting block moves down, the spring drives the pressure rod to move down. The pressure rod moves down and drives the opening and closing block to move down. The opening and closing block moves down and causes the rubber stopper block to move outward to open the discharge hole. The pressure rod presses the rubber stopper and discharges it from the discharge hole onto the disc. The pressure rod always presses the rubber stopper during the pressing process to ensure that it does not move. The feeding accuracy is high. Attached Figure Description
