Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lithium battery manufacturing, and in particular relates to a negative pressure pipeline detection device for lithium battery formation equipment. Background Art
[0002] Negative pressure is an essential step in the lithium battery formation process. However, electrolyte crystallization in high-temperature, low-dew-point environments can easily lead to blockage in the exhaust pipes. If not detected and addressed promptly, this can severely impact battery performance and even cause battery failure or safety incidents.
[0003] Existing technologies for testing negative pressure formation lines often use integrated testing cabinets. This requires a large number of testing devices, resulting in significant manufacturing or construction costs and hindering cost control for battery manufacturing. Existing production lines are often not suitable for upgrading or are prohibitively expensive to upgrade. Therefore, developing a lithium battery negative pressure line continuity testing tool with high accuracy, minimal workload, short maintenance time, high maintenance efficiency, ease of operation, and low cost is crucial for improving lithium battery production efficiency and safety.

[0019] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.
[0020] Example 1
[0021] refer to Figures 1 to 4The negative pressure pipeline detection device of a lithium battery formation equipment described in this embodiment includes a detection box 1, on which multiple groups of negative pressure channel ports 2 and multiple groups of pressure gauges 3 are installed. The input port of the negative pressure channel port 2 is detachably connected to the negative pressure detection pipeline through a pipeline, and the output end of the negative pressure channel port 2 and the input end of the pressure gauge 3 are connected one-to-one through a connecting pipe 4. The multiple groups of pressure gauges 3 are arranged in the detection box 1, and a filter 5 is installed on the connecting pipe 4. Each group of pressure gauges 3 is respectively connected to a group of negative pressure detection meters for processing, analyzing and displaying data in real time. The detection box 1 is also equipped with an alarm 8, and the negative pressure detection meters are all electrically connected to the alarm 8.
[0022] When in use, multiple groups of negative pressure channel ports 2 are connected one by one with the negative pressure detection pipeline through pipes, so that multiple groups of lithium battery negative pressure pipelines can be detected at the same time, thereby improving efficiency; the pressure gauge 3 monitors the negative pressure value of the negative pressure detection pipeline in real time through the connecting pipe 4, and the negative pressure detection gauge processes, analyzes and displays the data detected by the pressure gauge 3 in real time. When one or more groups of data are abnormal, the alarm 8 sounds an alarm to prevent the staff from missing the blocked negative pressure detection pipeline. At this time, the staff can accurately locate the abnormal negative pressure detection pipeline after checking one by one. This process does not require the staff to have professional industry knowledge and real-time monitoring. They only need to be responsible for plugging and unplugging the connecting pipeline and intervening when the alarm 8 sounds an alarm, which greatly provides convenience for enterprises and professionals; the filter 5 can effectively reduce the corrosion and damage of the negative pressure gauge caused by the reflux of the electrolyte in the formation pipeline, thereby improving the trouble-free working time and accuracy of the tooling and avoiding detection errors.
[0023] The detection box 1 has a built-in battery 6 , and the multiple groups of pressure gauges 3 are electrically connected to the battery 6 . The battery 6 is provided with a power display 62 . The detection box 1 is equipped with a switch 61 electrically connected to the battery 6 .
[0024] The built-in battery 6 facilitates the movement of the detection box 1 without being restricted by an external power cord, making it convenient to move it in the intelligent vertical warehouse for periodic testing; the switch 61 is used to turn the detection box 1 on and off, and the power display 62 facilitates the staff to observe and charge the battery 6 in time to avoid power outages during work.
[0025] Preferably, the negative pressure detection meter is wirelessly connected to an external monitoring device via a communication interface, and the alarm 8 is wirelessly connected to the monitoring device.
[0026] The negative pressure detection meter transmits data to the monitoring equipment in real time, and the monitoring equipment can uniformly display and monitor the data. When the pressure gauge 3 is found to be blocked, the monitoring equipment controls the alarm 8 to alarm. The monitoring equipment can also accurately display the number of the abnormal pressure gauge 3, which is convenient for the staff to quickly locate it.
[0027] A plurality of limit sleeves 7 are installed at the bottom of the detection box 1. The limit sleeves 7 can be detachably installed on a formation cabinet or a mobile vehicle.
[0028] The detection box 1 can be fixed on the formation cabinet for easy detection through the limiting sleeve 7, or fixed on a mobile vehicle for easy movement in the intelligent vertical warehouse. When periodic detection is required, the negative pressure detection pipeline within a certain range can be tested in batches. With the onboard battery 6, it is not affected by the position and can complete the detection quickly, thereby improving work efficiency.
