A detection mechanism for leaked punching

Abstract

This utility model relates to the field of battery pack assembly technology, specifically a detection mechanism for leaked holes. The mechanism includes a support frame, on which a fixture platform is fixedly connected. A stop screw is connected to the fixture platform, and the stop screw is connected to a positioning pin via a limiting spring. The positioning pin is connected to a through hole on a liquid cooling plate. A limit block is fixedly connected to the upper surface of the fixture platform via locking bolts. This utility model, through a detection mechanism composed of a stop screw, limiting spring, positioning pin, and limit block, can reduce the product defect rate, thereby reducing the likelihood of assembly failures due to leaked holes or misaligned holes. Furthermore, by quickly determining whether a product has leaked holes or misaligned holes using a fixture, it reduces manpower, material resources, and time costs, thus improving the product qualification rate.

Description

Technical Field

[0001] This utility model relates to the field of battery pack assembly technology, and in particular to a detection mechanism for leaked punching holes. Background Technology

[0002] With the rapid development of the new energy industry, liquid cooling technology, with its high-efficiency heat dissipation performance, is increasingly widely used in fields such as power batteries and energy storage equipment. As a core component of liquid cooling systems, the market demand for liquid cooling plates continues to rise. With the continuous expansion of application scenarios, the assembly requirements of liquid cooling plates and housings are becoming more diversified, placing higher demands on the convenience, reliability, and maintainability of assembly processes.

[0003] Currently, the most common assembly method in the industry is riveting assembly: the liquid cooling plate is fixed by riveting nuts, and the housing and liquid cooling plate are connected by bolts. This assembly method is widely used in production due to its advantages such as convenient operation and easy disassembly. However, in actual production, the hole accuracy of the liquid cooling plate has a significant impact on the assembly quality: if there is a hole misalignment problem in the cooling plate, it will directly lead to the inaccurate connection between the housing and the cooling plate, affecting assembly efficiency and structural stability; more seriously, if there is a missing hole, it will not only cause the assembly process to be interrupted, but also require the disassembly of the assembled parts for rework, increasing the difficulty of rework and production costs, and causing a significant obstacle to the production schedule. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a detection mechanism for leaked punching holes to solve the above-mentioned problem.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is: a detection mechanism for leaked punching holes, including a bracket, a gauge platform fixedly connected to the bracket, a stop screw connected to the gauge platform, the stop screw being connected to a positioning pin through a limiting spring, and the positioning pin being used to connect to the through hole of the liquid cooling plate.

[0006] As a preferred technical solution of this utility model, the upper surface of the inspection platform is fixedly connected to a limit block by locking bolts.

[0007] As a preferred embodiment of this utility model, the bottom end of the bracket is connected to two directional wheels and a swivel wheel.

[0008] As a preferred embodiment of this invention, the two directional wheels or omnidirectional wheels are located on the same side.

[0009] As a preferred embodiment of this utility model, the size and position of the positioning pin are adapted to the through hole.

[0010] Because this utility model adopts such a structure, the detection mechanism consisting of a stop screw, a limit spring, a positioning pin, and a limit block can reduce the product defect rate, thereby reducing the inability to assemble later due to product leaks or hole misalignment; on the other hand, the use of a tool to quickly determine whether the product has leaks or misaligned holes reduces the cost of manpower, material resources, and time, and can improve the product qualification rate.

[0014] In the diagram: 1 is the bracket, 2 is the inspection platform, 3 is the stop screw, 4 is the limit spring, 5 is the positioning pin, 6 is the limit block, 7 is the liquid cooling plate, 8 is the directional wheel, and 9 is the universal wheel. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-3 As shown, this utility model discloses a detection mechanism for leaked punching holes, comprising a bracket 1, on which a fixture platform 2 is fixedly connected. The fixture platform 2 is connected to a stop screw 3, which is connected to a positioning pin 5 via a limiting spring 4. The positioning pin 5 is used to connect with the through hole of a liquid-cooled plate 7. After the liquid-cooled plate 7 is placed on the fixture platform 2, the through holes on the liquid-cooled plate 7 correspond one-to-one with the positioning pins 5. By observing whether the positioning pin 5 passes through the hole on the liquid-cooled plate 7 or whether the product is tilted or uneven with the fixture platform 2, it can be determined whether the product has leaked holes or misaligned holes. This utility model is convenient, efficient, and practical.

[0017] Furthermore, in this invention, a limiting block 6 is fixedly connected to the upper surface of the inspection platform 2 by locking bolts. The limiting block 6 limits the liquid cooling plate 7, thereby improving inspection efficiency.

[0018] Furthermore, in this invention, the bottom end of the bracket 1 is connected to two directional wheels 8 and a universal wheel 9, with the two directional wheels 8 or universal wheels 9 located on the same side. The coordinated action of the directional wheels 8 or universal wheels 9 facilitates the movement of the inspection platform 2.

[0019] Furthermore, the size and position of the positioning pin 5 are adapted to the through hole. Through the positioning action of the positioning pin 5 and the through hole, the purpose of detecting the liquid cooling plate 7 is achieved.

[0020] The working principle of this utility model is as follows:

[0021] Place the liquid cooling plate 7 on the inspection platform 2 with the limiting block 6 as the limit. The positioning pin 5 passes through the hole on the liquid cooling plate 7 under the action of the limiting spring 5 and the fixing screw 3. Observe whether the positioning pin 5 passes through the hole on the liquid cooling plate 7 or whether the product is tilted or uneven with the inspection platform 2, so as to determine whether the product has a missing hole or the hole is misaligned.

Other variations and modifications can be made to the embodiments disclosed herein without departing from the spirit or essential characteristics of the utility model.
