Description

Technical Field

[0001] This utility model relates to the field of helium storage technology, specifically to a rapid helium exchange device. Background Technology

[0002] Existing helium supply structures for filling battery cells typically consist of one cylinder rack, one cylinder, and one cylinder / one machine, operating on a single-cylinder, single-machine basis. After the cylinder is used up, it needs to be replaced, resulting in frequent downtime for replacement. During cylinder replacement, the helium gauge is prone to damage and leakage, leading to cost losses. Furthermore, insufficient gas pressure during equipment restart can result in underfilled, out-of-specification battery cells, reducing the first-pass yield. Additionally, existing cylinder racks are relatively simple, consisting of simple welded steel pipes, and lack proper cylinder securing and protection, posing certain safety hazards. Utility Model Content

[0003] The purpose of this invention is to solve the problems of existing helium supply structures which are based on a single cylinder and single unit, requiring frequent replacements, easily damaging the gauges, causing leaks, and lacking protection for the cylinders.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rapid helium exchange device is characterized by comprising: a cylinder rack for placing two cylinders, a gas exchange component for supplying helium from the cylinders to the device, a front baffle detachably installed at the front end of the cylinder rack, and an adjustable clamping component disposed on the side wall of the cylinder rack for clamping the cylinders.

[0006] The ventilation assembly includes a three-way connector, an air supply pipe connected to the three-way connector for connecting the equipment, and a first air pipe and a second air pipe for connecting the gauges of two gas cylinders respectively. Both the first air pipe and the second air pipe are connected to air valves.

[0007] A further improvement is that the gas cylinder placement rack includes a base, a rear baffle connected to the rear end of the base, a partition plate connected to the middle of the base, and side baffles connected to both sides of the base.

[0008] A further improvement is that: several slots are provided on both sides of the partition plate and on the inward-facing side wall of the side baffle; plugs that are compatible with the slots are fixedly connected to both sides of the front baffle; and the front baffle can be detachably installed between the partition plate and the side baffle through the plugs cooperating with the slots.

[0009] A further improvement is that several of the aforementioned slots are spaced evenly at the front and back.

[0010] A further improvement is that a handle is provided at the upper end of the front baffle.

[0011] A further improvement is that the inner wall of the placement rack, the inner wall of the front baffle, and the inner wall of the adjustable clamp are all equipped with anti-collision pads.

[0012] A further improvement is that the anti-collision pad is a silicone rubber anti-collision pad.

[0013] A further improvement is that: a through hole is provided in the middle of the side baffle, and the adjustable clamping assembly includes a threaded seat installed on the outer side wall of the side baffle corresponding to the through hole. A screw is threadedly connected to the threaded seat. One end of the screw passes through the through hole and extends into the gas cylinder placement rack and is connected to an adjustable clamping plate. The other end of the screw passes through the threaded seat and is fixedly connected to a handwheel.

[0014] Compared with existing technologies, the above technical solution has the following advantages:

[0015] The adjustable clamps can be used to fix different gas cylinders, and the detachable front baffle can be used to limit the movement of the gas cylinders during use, thus better protecting the gas cylinders.

[0016] The three-way connector allows for gas supply from two gas cylinders. Each gas pipe has an independent gas valve, enabling gas exchange and resumption without shutting down the machine, extending the service life of the gas cylinders, reducing the probability of gauge damage, and preventing leaks caused by gauge damage.
