The first moving drive component 21 drives the adsorption component 25 to move above the first mold 33 via the first lifting drive component 22, and the second lifting drive component 23 drives the injection needle 24 to move above the first mold 33. The adsorption component 25... 5. First, the negative electrode shell is placed on the first mold 33, and then the battery cell assembly is placed inside the negative electrode shell; then the injection needle 24 injects the electrode liquid into the negative electrode shell, and the adsorption assembly 25 then puts the positive electrode cover on the negative electrode shell; the second moving drive assembly 31 drives the first mold 33 to move directly below the first mold 33, and the pressing and lifting drive assembly 32 drives the second mold 34 to move down and close with the first mold 33.

[0027] The detection component 5 includes, but is not limited to, a vision camera.

[0028] Specifically, the first moving drive component 21 drives the adsorption component 25 to move above the detection component 5 via the first lifting drive component 22. The detection component 5 can detect whether the battery cell component on the adsorption component 25 is qualified. If the battery cell component is qualified, the adsorption component 25 places the qualified battery cell component into the negative electrode shell; if the battery cell component is unqualified, the adsorption component 25 places the unqualified battery cell component into the waste box.

[0029] In this embodiment, the design of the detection component 5 improves the pass rate of the button battery assembled by the button battery assembly mechanism.

The first pulley is installed at the output end of the first motor 211, the second pulley 212 is installed on the first lead screw 214, the transmission belt 213 is wound around the first pulley and the second pulley 212, and the first nut 215 is installed on the support plate 216 and threadedly connected to the first lead screw 214.

[0033] In one embodiment, such as Figure 3As shown, the pressing and lifting drive assembly 32 includes a second motor 321, a first gear 322, a second gear 323, and a second lead screw 324. The second motor 321 is mounted on the support member 1. The first gear 322 is mounted on the output end of the second motor 321. The second gear 323 is mounted on the second lead screw 324 and meshes with the first gear 322. The diameter of the first gear 322 is smaller than the diameter of the second gear 323.

The material tray 4 is provided with five third storage slots 43 spaced apart, which are used to store the electrode, separator, lithium sheet, flat pad, and nickel foam, respectively.

[0038] Specifically, after the mold-closing component completes the assembly of the button battery, the second moving drive component 31 drives the first mold 33 away from the second mold 34, and the adsorption component 25 adsorbs the button battery from the first mold 33 and places it in the fourth storage slot 44.

[0039] In this embodiment, the material tray 4 can not only store the negative electrode shell, positive electrode cover and cell assembly, but also store the button battery.

[0042] In this embodiment, the pressure sensor can detect the pressure when the second mold 34 and the first mold 33 are closed in real time, ensuring the pressure when the second mold 34 presses against the first mold 33.

[0043] In one embodiment, such as Figure 1 As shown, the button battery assembly mechanism also includes a liquid storage container 11 mounted on the support component 1, the liquid storage container 11 being used to store electrolyte; The first moving drive component 21 is also used to drive the injection needle 24 to draw electrolyte from the liquid storage container 11 via the second lifting drive component 23.
