Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure cleaning tooling, in particular to a full-automatic tray type negative pressure cup cleaning tooling. Background Art

[0002] In battery formation test technology, it is often necessary to clean the negative pressure cup for battery electrolyte buffer. In the existing negative pressure cleaning tooling, different manufacturers have different schemes for the negative pressure cleaning process. For example, the common scheme 1: the circulation cleaning scheme with the trolley liquid storage and the cleaning tooling separated needs to be connected to the positive pressure system of the equipment as power, cut off the negative pressure system, and connect the remaining needle bed part of the negative pressure pipeline to perform liquid filling circulation operation on the negative pressure cup. It is not only cumbersome to operate, but also requires the cooperation of multiple people, and has the disadvantage of occupying the production site. The applicable scenarios are limited to small semi-automatic production lines and the production site has ample space.

[0003] Due to the obvious disadvantages of solution one, a second cleaning solution with integrated liquid storage and cleaning tooling was developed, that is, the liquid storage tank, empty tank and other tank bodies are placed inside the cleaning tooling, and the positive and negative pressure input interfaces connected to the outside world are reserved. In addition to connecting the cleaning tooling to the positive pressure system of the equipment, it is also necessary to connect it to the negative pressure system of the equipment to form an internal circulation of pipeline air, so that the tank liquid can be pressed into the negative pressure cup by injecting positive pressure gas.

[0004] The similarities between Option 1 and Option 2 are: the original negative pressure system needs to be manually spliced with pipes. Even if it is restored later, the airtightness of the negative pressure system may be damaged to a certain extent. The applicable scenarios of both are limited to small semi-automatic or small and medium-sized automatic production lines, and the equipment maintenance operation space needs to be ample.

Those skilled in the art can also select other types of power - taking modules 3 according to actual needs.

[0032] The detection control module includes a liquid level display and multiple liquid level sensors 7. Each branch of the bus pipe 9 is equipped with a liquid level sensor 7, and the liquid flow in each branch pipe is detected in real time through each liquid level sensor 7.

Each liquid level display can display the minimum liquid level design value of the circulation box 4 and the maximum capacity of the circulation box 4. The liquid level display is fixed on the side of the circulation box 4 to facilitate the filling and draining operations of the circulation box 4. Each liquid level sensor 7 is electrically connected to the liquid level display, and the liquid level display is used to display the information detected by each liquid level sensor 7. All connecting pipelines are corrosion-resistant hoses.

[0033] A liquid level sensor 7 is provided at the inlet and outlet of the circulation box 4, and the program is used to detect whether the liquid has completely reached the liquid recovery value. When the liquid recovery value is reached, the vacuum breaking preset normally closed valve on the negative pressure system is closed through program control, and the vacuum breaking positive pressure program is opened to blow dry each negative pressure cup. At this point, the negative pressure cup cleaning program is completed; the needle bed is opened, and the fully automatic tray-type negative pressure cup cleaning tooling is transported to the next station that needs to be cleaned through the logistics system, and so on, to complete the cleaning task.

[0034] This embodiment also includes a filter module 5 , which includes a forward filter and a reverse filter. The forward filter is installed between the circulation box 4 and the peristaltic pump 6 , and the reverse filter is installed between the peristaltic pump 6 and the bus pipe 9 .

The feedback pressure gauge 8 is used to detect the pressure in each pipeline and feed back the pressure signal to the outside. At the same time, the feedback pressure gauge 8 has a designed pressure value. By comparing the detected value of the feedback pressure gauge 8 with the designed pressure value, it is determined whether to trigger feedback, and then it is judged whether the negative pressure cup is blocked by electrolyte crystallization during the cleaning process, and this information is fed back to the program control module.

[0039] When the full-automatic tray type negative pressure cup cleaning tooling in this embodiment reaches the needle bed station, through the equipment debugging mode, the needle bed is pressed in place, and the nozzle docking seat 11 is docked with the negative pressure cup nozzles one by one to form a sealed structure; the probe spring contact device of the power taking module 3 is connected to the needle bed power supply structure to obtain electric energy; the normally closed electric valve with pre-set vacuum breaking on the negative pressure system is opened to make the negative pressure system pipeline communicate with the atmosphere; when the full-automatic tray type negative pressure cup cleaning tooling obtains electric energy, the internal cleaning system program is restarted, and by transmitting a remote WiFi signal, the full-automatic tray type negative pressure cup cleaning tooling permission can be obtained on the control room or maintenance laptop for remote operation.

[0040] When the full-automatic tray type negative pressure cup cleaning tooling in this embodiment is working, first start the peristaltic pump 6, and the DMC liquid in the circulation tank 4 with partitions inside flows into the peristaltic pump 6 through the corrosion-resistant pipeline after being filtered by the positive filter; the program control module controls the peristaltic pump 6 to flow the DMC liquid into the corresponding negative pressure cups of each single-point control valve 10 regularly and quantitatively according to the set program, and the rest of the negative pressure cups on the needle bed are filled with DMC liquid in turn, so that the DMC liquid in the negative pressure cup reaches a certain amount and does not exceed the capacity of the negative pressure cup to enter the needle bed busbar and pollute the pipeline system; after standing for a period of time, the electrolyte crystallization in the negative pressure cup is dissolved, and through a predetermined program, the peristaltic pump 6 rotates in reverse and the liquid is accelerated and transported back to the washing circulation tank 4 in turn, and the liquid entering the peristaltic pump 6 is filtered by the reverse filter to avoid blocking the peristaltic pump 6 and affecting the service life of the peristaltic pump 6.

[0041] For the problem of crystallization blockage, in this embodiment, the busbar pipeline 9 is connected to the feedback pressure gauge 8. By comparing the designed pressure value with the detected pressure value, it is judged whether to trigger feedback, and then it is judged whether the connection position of the minimum inner diameter nozzle of the negative pressure cup is blocked by electrolyte crystallization during the cleaning process, and then it is fed back to the program control module. The internal control program skips a certain blocked negative pressure cup position according to the real-time feedback and feeds it back to the control room or the maintenance laptop for subsequent fixed-point replacement of the nozzle or manual treatment.
