Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of chemical composition and capacity equipment, specifically relating to a detection device for flow rate and negative pressure in chemical composition and capacity equipment. Background Technology
[0002] Currently, in the battery manufacturing process, a formation process is required to improve battery performance. During this process, gas is generated inside the battery. Residual gas inside the battery will severely affect its performance. Therefore, it is necessary to extract the gas from the battery during the formation process. Existing technologies generally employ vacuum extraction systems to actively extract the gas from inside the battery. Accurate detection of flow rate and negative pressure parameters is a core technical aspect to ensure the effective operation of the extraction system.
[0003] In traditional testing methods, flow rate and negative pressure testing are typically performed using separate instruments. This requires manual switching of the testing pipeline interfaces, leading to low testing efficiency and increasing the risk of human error. Improper operation can result in inaccurate test results, consequently affecting battery performance and quality. Furthermore, traditional testing equipment lacks modular design and cannot achieve multi-channel parallel testing. When dealing with large-scale formation and capacity testing equipment, each station must be tested individually, severely impacting the overall equipment uptime. Summary of the Invention
[0004] This invention addresses the aforementioned problems by proposing a detection device for flow rate and negative pressure in a batching and dispensing equipment. The concept is to achieve switching between two detection modes—negative pressure and flow rate—through the opening and closing of a two-way valve and its linkage with a three-way interface. This integrates the two detection modes, avoiding the inefficiency caused by separate instruments or manual pipeline switching required for flow rate and negative pressure detection in existing technologies.
[0005] The detection device for flow rate and negative pressure of the batching and capacity equipment includes a base 1 and a test mechanism 2 installed on the upper surface of the base 1. The test mechanism 2 is surrounded by a baffle assembly 11 that connects to the base. The test mechanism 2 includes a number of test modules 21 arranged sequentially in the left-right direction. The test modules 21 are electrically connected to a detection interface 211 located outside the baffle assembly 11. The detection interface 11 is connected to the fluid channel of the external test device.
[0006] The test module 21 includes a negative pressure tester 218, which is connected to a flow tester 215 via a third pipe 214, a three-way interface 217, and a second pipe 213. The vertical opening of the three-way interface 217 is connected to the detection interface 211 via a first pipe 212. A two-way valve 216 that can be switched on and off is provided in the middle of the second pipe 213. A controller 3 connected to the two-way valve 216 is provided on the enclosure assembly 11.
[0007] More specifically, the enclosure assembly 11 includes a front fixing plate 113 located in front of the test mechanism 2, a rear fixing plate 114 located behind the test mechanism 2, a left side plate 111 located on the left side of the test mechanism 2, and a right side plate 112 located on the right side of the test mechanism 2.
[0008] More specifically, the base 1 is provided with several positioning bushings 13 that limit the position of the base 1.
[0009] More specifically, the first pipeline 212 is divided into a horizontal section 2121 and a bent section 2122, wherein the bent section 2122 is connected to the vertical opening of the tee interface 217, and the horizontal section 2121 is located above the second pipeline 213 and is connected to the detection interface 211.
[0010] More specifically, the two-way valve 216 is controlled electrically.
[0011] More specifically, the perimeter of the enclosure assembly 11 is provided with an operation panel 12, which is electrically connected to the controller 3.
[0012] The working steps of this utility model include:
[0013] 1. The base 1 is fixed in place by the positioning bushing 13, and the controller 3, the testing mechanism 2, and the operation panel 12 are powered on.
[0014] 2. The gas to be tested enters each test module 21 through the fluid channel and detection interface 211 of the external test mechanism. During the detection process of the test module 21, the gas to be tested enters the three-way interface 217 through the horizontal section 2121 and the bending section 2122 in sequence.
[0015] 3. The controller 3 controls the opening and closing of the two-way valve 216. When the two-way valve 216 is closed, the gas to be tested enters the negative pressure tester 218 through the third pipeline 214 for testing. When the two-way valve 216 is open, the gas to be tested enters the flow tester 215 through the two-way valve 216, and the flow tester 215 detects the flow rate of the gas.
[0016] The beneficial effects of this invention include: negative pressure and flow rate detection can be performed on the internal environment of the battery in the external negative pressure device through multiple test modules that integrate negative pressure detection and flow rate detection functions, avoiding the problem of low efficiency caused by separate instruments or manual switching of pipelines for flow rate and negative pressure detection in the prior art.
