[0029] The present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-3 As shown, the waste liquid collection component includes a collection plate 11 that can be close to or away from the injection head 33. The collection plate 11 is installed with a collection cup 12 that cooperates with the injection head 33. The collection cup 12 is provided with a drain port 14 that can drain the liquid in the collection cup 12.

[0031] When the filling head 33 that needs to be cleaned is close to the collection cup 12, the electrolyte in the filling head 33 can be discharged into the collection cup 12 under the action of positive pressure, and then the electrolyte in the collection cup 12 can be discharged outward through the drain port 14, so that the excess electrolyte in the filling head 33 can be discharged. When the next batch of batteries is filled, the electrolyte of the previous batch will not be mixed, thereby ensuring the quality of the filling.

[0032] Preferably, there are multiple collecting cups 12, and the collecting plate 11 is provided with multiple collecting holes 13 for installing the collecting plate 11. The collecting cups 12 are installed on the collecting plate 11 through the collecting holes 13. The provision of multiple collecting cups 12 can clean and drain multiple injection heads 33 at the same time, thereby further improving efficiency.

[0033] Furthermore, the collection cup 12 is equipped with a liquid extraction tube 15, which is connected to the discharge port 14. The liquid extraction tube 15 is connected to the pump body or the single-acting air pipe. Under the action of the pump body and the air pipe, the electrolyte in the collection cup 12 can be extracted and discharged, and will not stay in the collection cup 12 all the time. When there is a lot of electrolyte, overflow will not occur.

[0034] Furthermore, the collecting cup 12 has a truncated cone-shaped cup structure, and the outer diameter of the collecting cup 12 gradually decreases from top to bottom. The cup-shaped collecting cup 12 facilitates the top opening to cooperate with the injection head 33, so that most areas of the injection head 33 can be surrounded by the collecting cup 12, and the liquid discharged from the injection head 33 can enter the collecting cup 12 in a sealed manner.

[0035] A first lifting power member 2 and a second lifting power member 20 are provided below the collecting plate 11. The second lifting power member 20 is installed at the driving end of the first lifting power member 2, and the collecting plate 11 is installed at the driving end of the second lifting power member 20. The two-stage lifting is adopted, so that the lifting height of the collecting cup 12 installed on the collecting plate 11 is greater, preventing the occurrence of support instability under single action. After the collecting plate 11 is lowered away from the injection head 33, the collecting plate 11 will not affect it when the injection head 33 injects liquid into the battery clamp.

[0036] Specifically, the first lifting power component 2 includes a first bottom frame 21, on which a first lifting cylinder 22 is installed, and an intermediate plate 23 is installed on the top of the piston rod of the first lifting cylinder 22. The second lifting power component 20 includes a second lifting cylinder 24 installed on the intermediate plate 23, and the top of the piston rod of the second lifting cylinder 24 is connected to the collecting plate 11; when it is necessary to clean and collect the liquid, the first lifting cylinder 22 installed on the first bottom frame 21 drives the intermediate plate 23 to rise, and then the second lifting cylinder 24 installed on the intermediate plate 23 rises, so that the collecting plate 11 rises, and the rising height enables the collecting cup 12 to cooperate with the liquid injection head 33, and the liquid injection head 33 can be embedded in the collecting cup 12 to collect and discharge the electrolyte.

[0037] Preferably, the second lifting cylinder 24 is installed at the bottom of the middle plate 23, and the middle plate 23 is provided with a through slot 29 for the piston rod to pass through. When the second section of the collecting plate 11 is raised, the piston rod of the second lifting cylinder 24 is pushed out and passes through the through slot 29 to drive the collecting plate 11 to rise.

[0038] A first guide rod 25 is installed at the bottom of the middle plate 23, and a first guide sleeve 26 is installed at the bottom frame for guiding the sliding of the first guide rod 25. A second guide rod 27 is installed at the bottom of the collecting plate 11, and a second guide sleeve 28 is installed at the middle plate 23 for guiding the sliding of the second guide rod 27. The first guide sleeve 26 is used to guide the sliding of the first guide rod 25 longitudinally, so as to ensure that the middle plate 23 can be lifted and lowered vertically. Similarly, the second guide sleeve 28 is used to guide the sliding of the second guide rod 27 longitudinally, so as to ensure that the collecting plate 11 can be lifted and lowered vertically, so that the collecting cup 12 and the injection head 33 remain vertically coaxially aligned, and no displacement will occur during lifting and lowering.

[0039] The liquid injection and cleaning mechanism 3 includes a liquid injection chamber 31 and a waste liquid collection component 1. The liquid injection chamber 31 includes a liquid injection plate 32 and multiple liquid injection heads 33 arranged on the liquid injection plate 32. The liquid injection head 33 is longitudinally coaxially aligned with the collection cup 12. When the waste liquid collection component 1 approaches the liquid injection chamber 31, the collection cup 12 continuously approaches the liquid injection head 33 until the liquid injection head 33 is embedded in the collection cup 12. Multiple liquid injection heads 33 are respectively surrounded by corresponding collection cups 12, so that liquid drainage and cleaning can be achieved.

[0040] Furthermore, the liquid injection plate 32 is formed with a through hole 34 for the longitudinal movement of the liquid injection head 33, and a buffer sleeve 35 is installed through the hole 34 for buffering contact with the collection cup 12, and a bottom part of the buffer sleeve 35 can be deformed and embedded into the collection cup 12; the collection cup 12 continues to approach the liquid injection head 33 until the liquid injection head 33 is embedded in the collection cup 12, and the buffer sleeve 35 can play a sealing role. When the liquid from the liquid injection head 33 is injected into the collection cup 12, the buffer sleeve 35 can prevent the electrolyte from overflowing and causing leakage, thereby ensuring the sealing of the drainage.

[0041] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0042] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
