Description

A feeding fixture for the sealing ring of the explosion-proof valve in the lower housing Technical Field

[0001] This utility model relates to the field of lithium battery explosion-proof valve assembly technology, specifically to a lower housing explosion-proof valve sealing ring loading fixture, used for high-precision and high-efficiency assembly and loading of power or energy storage battery explosion-proof valve sealing rings. Background Technology

[0002] With the rapid development of the new energy industry, power batteries and energy storage batteries are widely used in automobiles, communication base stations, energy storage power stations, and other fields. If lithium batteries encounter abnormal conditions during charging and discharging (such as overcharging or internal short circuits), their internal temperature and pressure may rise rapidly, posing potential safety hazards. To avoid dangerous accidents caused by excessive internal pressure, an explosion-proof valve is usually installed on the lower casing (or shell) of the battery. When the internal pressure of the battery exceeds a set threshold, the explosion-proof valve will open or rupture, releasing the high-pressure gas inside and preventing the battery casing from rupturing or catching fire and exploding.

[0003] However, in practical applications, to ensure the airtightness of explosion-proof valves, it is usually necessary to add a gasket (or sealing ring) during the assembly process to isolate external air, moisture, and other impurities. This gasket requires high dimensional and positional accuracy; during assembly, it is essential to ensure that the gasket is correctly embedded in the corresponding sealing position of the explosion-proof valve. Otherwise, the seal may fail, thus negating the protective function of the explosion-proof valve.

[0004] In existing technologies, the installation of sealing rings typically relies on manual or semi-automated assembly methods. Due to the small size and thinness of the sealing rings, operators are prone to clamping and alignment errors during assembly, and fatigue or tool misoperation can also damage the sealing rings or cause improper assembly. More seriously, with the expansion of production capacity and the increase in automation, the efficiency and consistency of manual assembly are increasingly unable to meet the demands of mass production. Furthermore, if the position of the sealing ring is not precisely controlled during assembly, it is very easy for omissions or misassemblies to occur, thereby reducing the yield rate and increasing rework costs.

[0005] Based on the above issues, in order to improve assembly efficiency and yield, it is necessary to design a feeding fixture that can accurately, orderly and quickly deliver the explosion-proof valve sealing ring to the assembly station, thereby realizing an automatic or semi-automatic sealing ring assembly process. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a feeding fixture for the sealing ring of the explosion-proof valve in the lower housing. By precisely defining the relative position of the sealing ring and the valve body of the explosion-proof valve, and by quickly feeding and positioning the sealing ring, assembly efficiency and quality can be effectively improved, and labor costs and defect rates can be reduced.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a lower housing explosion-proof valve sealing ring feeding fixture, comprising a fixture base, a dual-station sealing ring feeding track, a movable block track, a movable block, a dual-station sealing ring feeding slot, and a stroke cylinder. The fixture base is provided with a dual-station sealing ring feeding track, and a movable block track is provided perpendicularly to the end of the dual-station sealing ring feeding track. A movable block is provided inside the movable block track, and a dual-station sealing ring feeding slot is provided on the movable block. One end of the movable block is connected to the cylinder rod of the stroke cylinder.

[0008] Preferably, both the movable block track and the dual-station feeding slot for the sealing ring are used to place the sealing ring.

[0009] The beneficial effects of this invention are as follows: This invention enables two independent workstations to perform loading, clamping, and positioning operations on a single fixture, improving assembly efficiency and ensuring the assembly accuracy and quality stability of the sealing rings. By optimizing the fixture structure design and coordinating with pneumatic or mechanical transmission mechanisms, automatic clamping, orientation, and placement of the sealing rings are achieved, thereby significantly improving production efficiency and reducing human error. Attached Figure Description

[0010] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0011] Figure 1 is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Referring to Figure 1, the specific embodiment adopts the following technical solution: a lower housing explosion-proof valve sealing ring feeding fixture, including a fixture base 1, a dual-station sealing ring feeding track 2, a movable block track 3, a movable block 4, a dual-station sealing ring feeding slot 5, and a stroke cylinder 6. The fixture base 1 is provided with a dual-station sealing ring feeding track 2, and a movable block track 3 is provided at the end of the dual-station sealing ring feeding track 2, which is perpendicular to it. A movable block 4 is provided inside the movable block track 3, and a dual-station sealing ring feeding slot 5 is provided on the movable block 4. One end of the movable block 4 is connected to the cylinder rod of the stroke cylinder 6.

[0014] It is worth noting that the movable block track 3 and the dual-station feeding slot 5 for sealing rings are both used to place sealing rings 7.

[0015] The working principle of this specific implementation method is as follows: the stroke cylinder pushes the moving block. When the moving slot of the moving block is aligned with the sealing ring feeding track, the sealing ring moves slowly forward along the feeding track under the force of the external cylinder. Finally, under the action of gravity, it falls and flips into the dual-station feeding slot. Finally, it moves to the loading station under the push of the stroke cylinder, and is assembled by the external mechanical suction cup.

[0016] This specific implementation uses a parallel dual-station feeding track and feeding slot, combined with precise pushing by a stroke cylinder, to achieve continuous alternating feeding of sealing rings. This avoids the idle waiting time of single-station equipment, theoretically increasing production efficiency by nearly 100%. The sealing rings autonomously flip and fall into the feeding slot under gravity. Combined with the limiting structure of the moving block track, this ensures that the sealing rings are not forcibly squeezed or deformed during transportation, making it particularly suitable for non-destructive feeding of elastic material sealing rings (such as fluororubber and silicone rings). The dynamic alignment mechanism of the moving block slot and the feeding track can accommodate sealing rings of different diameters (±2mm tolerance range); the cylinder drive stroke is programmable and adjustable, enabling rapid switching of production models to meet the assembly needs of small-batch, multi-variety explosion-proof valves.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
