Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 7 This utility model proposes a negative pressure cleaning fixture.

[0030] The negative pressure cleaning fixture includes a base frame 100, a first negative pressure component 200, a second negative pressure component 300, a first liquid storage tank 400, and a second liquid storage tank 500. The first negative pressure component 200 has multiple first negative pressure holes 201; the second negative pressure component 300 has multiple second negative pressure holes 301; the first liquid storage tank 400 is connected to the negative pressure pipeline of the testing equipment through the multiple first negative pressure holes 201; the first liquid storage tank 400 and the second liquid storage tank 500 are connected, and the second liquid storage tank 500 is connected to the negative pressure pipeline of the testing equipment through the multiple second negative pressure holes 301; at least one of the first liquid storage tank 400 and the second liquid storage tank 500 stores cleaning fluid, and the cleaning fluid can flow from the first liquid storage tank 400 into the second liquid storage tank 500 through the negative pressure pipeline of the testing equipment, or from the second liquid storage tank 500 into the first liquid storage tank 400 through the negative pressure pipeline of the testing equipment.

[0031] Specifically, the stacker crane places the negative pressure cleaning fixture into the storage location of the testing equipment. The negative pressure nozzle on the negative pressure pipeline of the testing equipment presses against the first negative pressure hole 201 and the second negative pressure hole 301 to form a sealed channel. The host computer sends an instruction to the PLC control unit of the negative pressure cleaning fixture. The PLC control unit retrieves the corresponding program. The air path controls the cleaning fluid to enter the negative pressure pipeline of the testing equipment from the first storage tank 400 through the first negative pressure hole 201, and then from the negative pressure pipeline of the testing equipment through the second negative pressure hole 301 and into the second storage tank 500. After cleaning is completed, when cleaning the negative pressure pipeline of the next testing equipment, the cleaning fluid enters the negative pressure pipeline of the testing equipment from the second storage tank 500 through the second negative pressure hole 301, and then from the negative pressure pipeline entering the testing equipment through the first negative pressure hole 201 into the first storage tank 400, completing the program setting instructions. With this setup, the two liquid storage tanks circulate and clean the negative pressure pipeline of the testing equipment, achieving multi-channel cleaning of the negative pressure pipeline and improving cleaning efficiency. The repeated cleaning of the negative pressure pipeline by the two liquid storage tanks results in better cleaning effect.

[0032] Please see Figures 1 to 7Furthermore, the first negative pressure assembly 200 includes a first mounting component 210, a first negative pressure block 220, and a first comb plate 230. The first mounting component 210 is provided with a first mounting groove 211, and the bottom of the first negative pressure block 220 is engaged in the first mounting groove 211. The first comb plate 230 is provided with a plurality of first limiting grooves 231, and the top of the first negative pressure block 220 is engaged in the first limiting grooves 231. Specifically, the first comb plate 230 can directly limit the first negative pressure block 220, ensuring the assembly stability of the first negative pressure block 220. During assembly, the first comb plate 230 is first fixed on the first mounting part 210. The first limit grooves 231 of the first comb plate 230 can pre-position each first negative pressure block 220, ensuring that the first negative pressure block 220 is accurately assembled into the first mounting part 210. This ensures that the negative pressure nozzle of the negative pressure pipeline of the subsequent testing equipment can be accurately positioned at the first negative pressure hole 201 of the first negative pressure block 220, forming a closed channel for cleaning.

[0033] Please see Figures 1 to 7 Furthermore, the second negative pressure assembly 300 includes a second mounting member 310, a second negative pressure block 320, and a second comb plate 330. The second mounting member 310 is provided with a second mounting groove 311, and the bottom of the second negative pressure block 320 is engaged in the second mounting groove 311. The second comb plate 330 is provided with a plurality of second limiting grooves 331, and the top of the second negative pressure block 320 is engaged in the second limiting grooves 331. Specifically, the second comb plate 330 can directly limit the second negative pressure block 320, ensuring the assembly stability of the second negative pressure block 320. During assembly, the second comb plate 330 is first fixed on the second mounting part 310. The second limit grooves 331 of the second comb plate 330 can pre-position each second negative pressure block 320, ensuring that the second negative pressure block 320 is accurately assembled into the second mounting part 310. This ensures that the negative pressure nozzle of the negative pressure pipeline of the subsequent testing equipment can be accurately positioned at the second negative pressure hole 301 of the second negative pressure block 320, forming a closed channel for cleaning.

[0034] Please see Figures 1 to 7Furthermore, a first manifold 600 and a second manifold 700 are installed inside the bottom frame 100. The first manifold 600 connects to the first liquid storage tank 400 and to multiple first negative pressure holes 201. The second manifold 700 connects to the second liquid storage tank 500 and to multiple second negative pressure holes 301. Specifically, the first manifold 600 and the second manifold 700 serve a confluence function. When the cleaning fluid from the first liquid storage tank 400 flows into the negative pressure pipeline of the testing equipment, the first manifold 600 collects the cleaning fluid from the first liquid storage tank 400 and flows out from each branch point, corresponding to the multiple first negative pressure holes 201. Conversely, the cleaning fluid in the negative pressure pipeline of the testing equipment can enter and flow into the first liquid storage tank 400 from the branch point of the first manifold 600; the second manifold 700 works similarly.

[0035] Please see Figures 1 to 7 Furthermore, the first manifold 600 is provided with a first connector 610 for connecting to the first liquid storage tank 400, and also with a plurality of second connectors 620 for correspondingly connecting to the first negative pressure hole 201.

[0037] Please see Figures 1 to 7 Furthermore, the first storage tank 400 is equipped with a first drain valve 800 for discharging the cleaning fluid, and the second storage tank 500 is equipped with a second drain valve 900 for discharging the cleaning fluid. After the cleaning fluid has cleaned the negative pressure pipeline of the testing equipment a certain number of times, the first drain valve 800 and the second drain valve 900 can be opened to drain the cleaning fluid and replenish the cleaning fluid to the first storage tank 400 or the second storage tank 500.

[0038] Please see Figures 1 to 7 Furthermore, the first negative pressure block 220 and the second negative pressure block 320 are T-shaped. This allows for easy assembly of the first negative pressure block 220 and the second negative pressure block 320 into the first mounting groove 211 and the second mounting groove 311, achieving rapid positioning.

[0039] The specific steps of the cleaning method using this negative pressure cleaning fixture are as follows:

[0040] Step S1: Connect the first liquid storage tank 400 and the second liquid storage tank 500 to the negative pressure pipeline of the same testing equipment;
