[0071] In one embodiment, such as Figure 8As shown, the wiping assembly 37 also includes a wiping nozzle 379 and a reagent bottle 370 for storing wiping agent; the wiping nozzle 379 is mounted on the wiping slide plate 378, the reagent bottle 370 is mounted on the infrared base 32, the wiping nozzle 379 is connected to the reagent bottle 370, and the wiping nozzle 379 is used to spray wiping agent onto the wiping belt between the third guide roller 376 and the fourth guide roller 377.

[0072] Specifically, the wiping nozzle 379 can spray the wiping agent in the reagent bottle 370 onto the wiping belt between the third guide roller 376 and the fourth guide roller 377. The wiping belt, moistened by the wiping agent, then wipes the test boss 311, ensuring the cleanliness of the test boss 311 by the wiping assembly 37.

[0073] In one embodiment, such as Figure 1 and Figure 11 As shown, the automatic electrolyte detection equipment also includes a double capping mechanism 5, which includes a capping seat 51, a capping lifting drive 52, a capping rotating drive 53, a second clamping assembly 54, a third clamping assembly 55, and a storage plate 56.

[0074] The cap lifting drive 52 and the storage plate 56 are both mounted on the cap mounting base 51. The cap rotating drive 53 is mounted on the output end of the cap lifting drive 52, and the second clamping assembly 54 is mounted on the output end of the cap rotating drive 53. The storage plate 56 is provided with a first cover groove and a second cover groove that are spaced apart. The first cover groove is used to store the cover 400 of the test dish 200, and the second cover groove is used to store the cover 300 of the liquid storage tank 100.

[0075] The second clamping component 54 is used to clamp the dish cap 400 and the can cap 300, and the third clamping component 55 is used to clamp or release the detection dish 200 and the liquid storage tank 100; the transfer mechanism 1 is also used to transfer the detection dish 200 and the liquid storage tank 100 to the third clamping component 55.

[0077] Specifically, the transfer mechanism 1 transfers the liquid storage tank 100 with the lid 300 onto the second clamping assembly 54. The second clamping assembly 54 clamps the liquid storage tank 100. The cap-screwing lifting drive 52 drives the third clamping assembly 55 to move downwards. The third clamping assembly 55 clamps the lid 300. The cap-screwing lifting drive 52 drives the third clamping assembly 55 to rotate, thus removing the lid 300 from the liquid storage tank 100. The cap-screwing rotation drive 53 then drives the third clamping assembly 55 to move above the second cover slot, where the lid 300 can be placed. The double-capping mechanism 5 opens the testing dish 200 in the same way as it opens the liquid storage tank 100, and will not be described again here. The transfer mechanism 1 can also transfer the opened liquid storage tank 100 from the third clamping assembly 55 to the second storage slot, and the opened testing dish 200 from the third clamping assembly 55 to the first storage slot.

[0078] In this embodiment, the double-twist cap mechanism 5 can open the detection dish 200 and the storage tank 100, thereby improving the automation level of the electrolyte automatic detection equipment.

The barcode scanner 59 is arranged opposite to the barcode scanning disk 58 and is used to scan the label on the liquid storage tank 100.

[0080] The labels include, but are not limited to, QR codes, barcodes, etc., and can be used to label the electrolyte in the storage tank 100; the scanning rotary drive 57 includes, but is not limited to, a motor.

[0081] Specifically, the transfer mechanism 1 first places the storage tank 100 covered with the lid 300 on the barcode scanner 58. The barcode scanner 57 drives the storage tank 100 to rotate through the barcode scanner 58. The barcode scanner 59 can scan the label on the storage tank 100 to obtain information about the electrolyte in the storage tank 100. Then, by comparing the conductivity and chemical properties of the electrolyte, the quality of the electrolyte stored in the storage tank 100 is determined to be qualified.

[0082] To further explain, the transfer mechanism 1 can also transfer the liquid storage tank 100 on the barcode scanner 58 to the third clamping assembly 55.

[0083] In one embodiment, such as Figure 1As shown, the automatic electrolyte detection device further includes a storage mechanism 6, which includes a storage base 64 and a first support plate 61, a second support plate 62 and a third support plate 63 spaced apart on the storage base 64; the first support plate 61 is used to store a tray on which the storage tank 100 is installed, the second support plate 62 is used to store a detection dish 200, and the third support plate 63 is used to store a stopper cap 500;

[0084] The transfer mechanism 1 is also used to pick up the liquid storage tank 100, the test dish 200 and the stopper 500 from the storage mechanism 6.

[0085] The first support plate 61, the second support plate 62, and the third support plate 63 are arranged at intervals along the vertical direction. The transfer mechanism 1 transfers the liquid storage tank 100 on the first support plate 61 to the barcode scanner 58, transfers the detection dish 200 on the second support plate 62 to the third clamping assembly 55, and transfers the cap 500 on the third support plate 63 to the first clamping arm 206.

[0086] In this embodiment, the storage mechanism 6 can store multiple liquid storage tanks 100, multiple testing dishes 200, and multiple stoppers 500.

[0087] In one embodiment, such as Figure 3 As shown, the first clamping assembly 13 includes a second opening and closing drive member 131 and two second clamping arms 132 installed at the output end of the second opening and closing drive member 131. The second opening and closing drive member 131 is installed on the robotic arm 12. A first clamping groove 1321, a second clamping groove 1322 and a third clamping groove 1323 are provided between the two second clamping arms 132. The first clamping groove 1321 is used to clamp the detection dish 200, the second clamping groove 1322 is used to clamp the liquid storage tank 100, and the third clamping groove 1323 is used to clamp the stopper cap 500.

[0088] The second opening and closing drive component 131 includes, but is not limited to, a clamping cylinder, a clamping electric cylinder, etc., and the second opening and closing drive component 131 can drive the second clamping arms 132 to move closer to each other or further apart.

[0089] In this embodiment, the first clamping component 13 can clamp the liquid storage tank 100, the detection dish 200 and the stopper 500, thereby improving the applicability and versatility of the first clamping component 13.

[0090] The working steps of this automatic electrolyte testing equipment are as follows:

[0091] The transfer mechanism 1 transfers the liquid storage tank 100 (with lid 300) on the first support plate 61 to the barcode scanner 58, transfers the test dish 200 (with lid 400) on the second support plate 62 to the third clamping assembly 55, and transfers the stopper 500 on the third support plate 63 to the first clamping arm 206; the double-tightening cap mechanism 5 completes the opening of the liquid storage tank 100 and the test dish 200; the transfer mechanism 1 transfers the opened test dish 200 on the third clamping assembly 55 to the first storage slot, and transfers the opened liquid storage tank 100 on the third clamping assembly 55 to the second storage slot; the pipette 35 docks with the second storage slot and draws liquid from the liquid storage tank 100. After electrolyte removal, the pipette 35 is connected to the first storage tank and injects the electrolyte into the detection dish 200. The pipette 35 is then connected to the infrared spectroscopy detection stage 31 and drops the electrolyte onto the infrared spectroscopy detection stage 31. The transfer mechanism 1 transfers the detection dish 200 from the first storage tank to the Raman seat 42. The conductivity detection mechanism 2 measures the conductivity of the electrolyte in the storage tank 100 at different temperatures, the infrared detection mechanism 3 measures the infrared spectrum of the electrolyte, and the Raman detection mechanism 4 measures the Raman spectrum of the electrolyte in the detection dish 200. The stopper 500 on the first clamping arm 206 is then placed on the storage tank 100. Finally, the transfer mechanism 1 completes the unloading of the detection dish 200 and the storage tank 100 after testing.
