[0050] As shown in [Fig. 3], the first end 1321 and the second end 1322 of the liquid collection assembly 132 relate to the fact that, when the plurality of liquid collection elements 134 are in an unfolded state along the first direction X, the liquid collection element 134 disposed at one end is fixedly installed on the console 131 and forms the first end 1321, and the liquid collection element 134 disposed at the other end is movable along the first direction X and forms the second end 1322.

[0067] As shown in [Fig.8], by way of example of preferred form, the disc-forming ear 1345 is formed by bending the edge of the second lateral wall body 1344. Along the third direction Z, one end of the second lateral wall body 1344 is connected to the lower wall 1341, and the other end is bent outwards to form a disc-forming ear 1345.

[0088] According to the structural characteristics of the negative pressure forming equipment 100, the probe assembly 140 can be arranged entirely on the lower side of battery placement area 111, or may be partially disposed on the lower side of battery placement area 111.

[0089] With the above structure, in the case where the liquid collection assembly 132 is in a liquid collection state, the electrolyte can be prevented from dripping down to at least part of the probe assembly 140 on the lower side of the battery placement area 111, thus preventing corrosion of the probe assembly 140.

[0090] Since the negative pressure forming equipment 100 of the embodiment of the present application includes a liquid collection assembly 132, the liquid collection assembly 132 can switch between the liquid collection state and the avoidance state, which can prevent the electrolyte from falling below the negative pressure mechanism and causing corrosion of other mechanisms on the lower side of the negative pressure mechanism or causing work-related accidents to workers when they come into contact with it, so that the effective service life and safety performance of the negative pressure forming equipment are increased.

[0091] Finally, it should be noted that the above embodiments are used only to illustrate the technical solutions of the present application, and not to limit them; although the application has been described in detail with reference to the above embodiments, a person with ordinary competence in the art should understand that it is still possible to make modifications to the technical solutions listed in the above embodiments, or to make equivalent replacements of all or part of the envisaged technical features; and such modifications or replacements do not exclude the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
