[0022] The technical solutions in the embodiments of the application are described below in detail and in full with reference to the drawings in those embodiments. Naturally, the described embodiments represent not all, but only a subset of the embodiments in the application. All other embodiments that a person skilled in the art could obtain from the embodiments in the application without inventive steps are also within the scope of protection of the application.

[0023] In the present application, the terms "top", "bottom", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "center", "vertical", "horizontal", "transverse", "longitudinal", etc. are used in each case in relation to the directional or positional relationship shown in the respective illustration. Such terms serve only to better describe the application and its embodiments, without indicating the positioning, design, and operation of the device, element, or component in question in a predetermined position.

[0024] Furthermore, some of the above terms could serve to indicate other meanings besides the directional or positional relationship. For example, the term "on / to" could in some cases also indicate a specific allocation or connection relationship. The specific meaning of the above terms in the present application can be understood by the person skilled in the art in the art, taking into account the specific circumstances.

[0025] In related technology, a vacuum formation system could be corroded by leaking electrolyte from a battery and by remaining electrolyte in a vacuum suction nozzle during formation in vacuum technology, which not only shortens the service life of the vacuum formation system but also causes a certain safety risk.

[0026] As can be seen from Fig. 1 results in a vacuum formation system 100 according to some embodiments of the present application being used for forming a battery under vacuum and is characterized by long service life and good safety performance.

[0027] As in Fig. 1, Fig. 2 and Fig. As shown in Figure 3, the vacuum formation system 100 comprises a frame 110, a vacuum mechanism 120, and a collection mechanism 130. The frame 110 has a battery storage area 111. The vacuum mechanism 120 is arranged on the frame 110 and is located above the battery storage area 111. The collection mechanism 130 is arranged on the frame 110 and comprises a collection device 132. The collection device 132 is switchable between a collection state and an escape state. When the collection device 132 is in the collection state, it is configured to collect the electrolyte dripping from the vacuum mechanism 120 from below the vacuum mechanism 120. When the collection device 132 is in the avoidance state, the collection device 132 is configured to avoid a battery in the battery storage area 111 and the vacuum mechanism 120.

[0028] In the vacuum forming plant 100 according to the embodiments of the present application, the collection device 132 is switchable between the collection state and the escape state. This provides a space for connecting a battery to the vacuum mechanism 120 during vacuum forming and allows the electrolyte dripping from the vacuum mechanism 120 to be collected from below it after the vacuum forming process is complete. This prevents the electrolyte from dripping under the vacuum mechanism 120, thus avoiding corrosion of other mechanisms below the vacuum mechanism 120 and preventing operator injury upon contact. This extends the effective service life of the vacuum forming plant 100 and improves its safety performance.

[0029] The extent of the battery storage area 111 refers to the spatial extent required for a battery located below the vacuum mechanism 120 and its connection to the vacuum mechanism 120 and a probe assembly 140 during vacuum formation. When the collection device 132 is in the deflection position, it is configured to deflect the spatial extent required for connecting a battery in the battery storage area 111 to the vacuum mechanism 120, thus ensuring the normal execution of vacuum formation.

[0030] To facilitate the loading and unloading of a battery from the battery storage area 111, the vacuum forming system 100 can include an electric roller conveyor mechanism, thus enabling automated battery transport. During the forming process, the battery remains in the battery storage area 111. Alternatively, the vacuum forming system 100 can include a storage plate, and a battery can be inserted into the battery storage area 111 either by an external robotic arm or manually.

[0031] As in Fig. As shown in Figure 1, the vacuum mechanism 120 comprises a mounting bracket and a vacuum assembly 121. The vacuum assembly 121 is connected to the frame 110 via the mounting bracket. A vacuum port 1214 is provided on the underside of the vacuum assembly 121.

[0032] In detail, the vacuum assembly 121 comprises a vacuum cup, a connecting tube, and a suction nozzle. The vacuum cup is mounted on the mounting bracket and connected to a vacuum suction device. The underside of the vacuum cup is connected to the suction nozzle via the connecting tube. One end of the suction nozzle is connected to the connecting tube, and the other end is the vacuum port 1214, which serves for connection to an electrolyte filler port of a battery.

[0033] The collection mechanism 130 serves to collect the electrolyte dripping from the vacuum port 1214 after completion of the formation under vacuum, thus preventing the electrolyte from dripping onto another mechanism arranged below it or onto the skin of an operator.

[0034] As can be seen from Fig. 1, Fig. 2 and Fig. As shown in Figure 3, in some embodiments of the application, the catch mechanism 130 comprises a holder 131 and a catch device 132. The holder 131 is mounted on the frame 110. In a first direction X, the catch device 132 comprises a first end 1321 and a second end 1322. The catch device 132 can extend and retract in the first direction X, thereby switching between the catch state and the avoidance state.

[0035] In some embodiments of the application, the first end 1321 is fixedly mounted to the holder 131 and the second end 1322 is slidably mounted to the holder 131 in the first direction X. In another embodiment, it is conceivable that both the first end 1321 and the second end 1322 are slidably mounted to the holder 131 in the first direction X.

[0036] As in Fig. 2 and Fig. As shown in Figure 4, the holder 131 comprises two sliding-slot plates, two mounting plates 1313, a top plate 1314, and several support elements 1315. The top plate 1314 is mounted on the frame 110. The longitudinal direction of the sliding-slot plate runs in the first direction X. The longitudinal direction of the mounting plate 1313 runs in a second direction Y. The two sliding-slot plates are arranged opposite each other in the second direction Y. The two mounting plates 1313 are arranged opposite each other in the first direction X. The two sliding-slot plates are connected to each other on the same side via a mounting plate 1313. The two mounting plates 1313 and the two sliding-slot plates together form a frame structure. Alternatively, two sliding-slot plate mounting plates can be provided, so that the two sliding-slot plate mounting plates and the two mounting plates 1313 together form a frame structure.

[0037] The longitudinal direction of the support element 1315 runs in a third direction Z. The support element 1315 is connected to the frame structure and the top plate 1314. The space between the top plate 1314 and the frame structure serves to accommodate the vacuum mechanism 120.

[0038] The two sliding groove plates are each provided with a sliding groove (not shown) on their facing sides, which runs in the first direction X and serves to mount the collecting device 132.

[0039] As can be seen from Fig. 3, Fig. 5 and Fig. 6 results in the collecting device 132 in some embodiments of the application comprising at least two collecting elements 134 and the at least two collecting elements 134 can be unfolded or folded in the first direction X.

[0040] As one exemplary embodiment, the number of collecting elements 134 is three. In another embodiment, the number of collecting elements 134 can also be two, four, five, etc.

[0041] As in Fig. As shown in Figure 3, the first end 1321 and the second end 1322 of the collecting device 132 are understood to mean that the collecting element 134 located at one end is fixed to the holder 131 and forms the first end 1321, and the collecting element 134 located at the other end is movable in the first direction X and forms the second end 1322 when the multiple collecting elements 134 are unfolded in the first direction X.

[0042] This facilitates the switching of the collection device 132 between the collection state and the evacuation state. When the collection device 132 is in the evacuation state, the need for an external space is eliminated.

[0043] In another embodiment, the at least two collecting elements 134 can also be unfolded or folded in a different direction. Alternatively, sufficient space is provided to allow the removal of the at least two collecting elements 134 from the battery storage area 111 in the unfolded state.

[0044] As can be seen from Fig. 5 and Fig. As shown in section 6, in some embodiments of the application, the two adjacent collecting elements 134 are extended when the collecting device 132 is in the collecting state. The two adjacent collecting elements 134 are retracted vertically when stacked one above the other, when the collecting device 132 is in the retraction state.

[0045] As an exemplary embodiment, the third direction Z is the vertical direction. The two adjacent collecting elements 134 are moved in the first direction X and retracted in the third direction Z for stacking on top of each other when the collecting device 132 is in the avoidance state.

[0046] In this way, a small space is occupied by the collection device 132 which is in the escape state.

[0047] In another embodiment, the two adjacent collecting elements 134 can also be retracted in the first direction X for stacking on top of each other when the collecting device 132 is in the retracted position. For example, the collecting device 132 can also be a bellows cover.

[0048] As in Fig. 5, Fig. 6, Fig. 7 and Fig. As shown in Figure 8, in some embodiments of the application, the receiving element 134 comprises a bottom wall 1341, two first side walls 1342, and two second side walls 1343. The two first side walls 1342 are arranged opposite each other in the first direction X on the bottom wall 1341. The two second side walls 1343 are arranged opposite each other in the second direction Y on the bottom wall 1341. The bottom wall 1341, the two first side walls 1342, and the two second side walls 1343 together enclose a receiving chamber.

[0049] In this way, the collecting element 134 can collect the electrolyte dripping from the vacuum mechanism 120 and has a large collecting area.

[0050] In another embodiment, the side wall of the collecting element 134 can also have a different shape.

[0051] In some embodiments of the application, the collecting device 132 further comprises an absorption element 135. The absorption element 135 is interchangeably arranged in the receiving chamber and serves to absorb the electrolyte.

[0052] The absorption element 135 absorbs electrolyte, and by replacing the absorption element 135, the collected electrolyte is removed in a timely manner. Furthermore, the connection points between the bottom wall 1341, the first side walls 1342, and the second side walls 1343 can be made less sealed.

[0053] As one exemplary embodiment, the absorption element 135 can be made of nonwoven fabric and adapted to the contour of the receiving space. In another embodiment, the absorption element 135 can also be made of sponge or another material with high liquid absorption capacity. The absorption element 135 can, among other things, be granular or fragmented.

[0054] In another embodiment, the absorption element 135 can be omitted and electrolyte is drained by providing an electrolyte outlet hole in the absorption element 135.

[0055] As in Fig. As shown in Figure 8, in some embodiments of the application, the second side wall 1343 comprises a body of the second side wall 1344 and a nose 1345. The nose 1345 projects from the outside of the second side wall 1343 in the second direction Y. The nose 1345 is slidably fitted to the holder 131 in the first direction X.

[0056] In detail, each of the second side walls 1343 includes a nose 1345. Each of the noses 1345 projects from the outside of the associated body of the second side wall 1344 and is inserted into the sliding groove of the sliding groove plate on the same side. The nose 1345 is slidably fitted to the respective sliding groove in the first direction X.

[0057] Several options are available for forming the nose 1345. The nose 1345 can be attached to the outside of the body of the second side wall 1344 by welding, assembly, etc., or alternatively, it can be formed by extending an edge of the body of the second side wall 1344.

[0058] As in Fig. As shown in Figure 8, the nose 1345 is formed as a preferred exemplary embodiment by bending the edge of the body of the second side wall 1344. In the third direction Z, one end of the body of the second side wall 1344 is connected to the bottom wall 1341 and the other end is bent outwards, thus forming the nose 1345.

[0059] In another embodiment, the collecting element 134 can be fitted to the holder 131 in a slidable manner in the first direction X.

[0060] In some embodiments of the application, the first side wall 1342 is a bend formed by bending the bottom wall 1341, and / or the second side wall 1343 is a bend formed by bending the bottom wall 1341.

[0061] That is, the two edges of the bottom wall 1341 in the first direction X are bent, thus forming the two first side walls 1342, and the two edges of the bottom wall 1341 in the second direction Y are bent, thus forming the two second side walls 1343.

[0062] As an exemplary embodiment, the edges of the bottom wall 1341 in the first direction X are first bent inwards, thus forming the bodies of the second side wall 1344, and then bent outwards, thus forming the noses 1345. The edges of the bottom wall 1341 in the second direction Y are continuously bent inwards, thus forming the first side walls 1342 and keeping the edges of the first side walls 1342 smooth.

[0063] In this way, the forming of the collecting element 134 can be simplified, the forming efficiency of the collecting element 134 can be increased and the manufacturing costs of the collecting element 134 can be reduced.

[0064] In another embodiment, the bottom wall 1341, the first side walls 1342 and the second side walls 1343 can be joined together to form a whole by assembly.

[0065] As in Fig. As shown in Figure 7, in some embodiments of the application the collecting element 134 further comprises a hook section 1346. The hook section 1346 is arranged on the underside of the bottom wall 1341 and serves to abut the first side wall 1342 of another adjacent collecting element 134 in order to limit the relative end positions of two adjacent collecting elements 134.

[0066] As an exemplary embodiment, the hook section 1346 is formed using bending technology and connected to the underside of the base wall 1341 by welding. The hook section 1346 is arranged close to the other, matching catch element 134 in the first direction X. The hook section 1346 rests against the inside of one of the first side walls 1342 of the other catch element 134 to limit the end position in the unfolded state, and rests against the inside of the other first side wall 1342 of the other catch element 134 to limit the end position in the folded state.

[0067] As can be seen from Fig. As shown in Figure 5, in some embodiments of the application, the positions of the multiple collecting elements 134 with respect to their heights in the third direction Z are arranged in ascending order in the unfolding direction, and the hook section 1346 is arranged in a direction opposite to the unfolding direction on the bottom wall 1341. In another embodiment, the positions of the multiple collecting elements 134 with respect to their heights in the third direction Z are arranged in descending order in the unfolding direction, and the hook section 1346 is arranged in a direction corresponding to the unfolding direction on the bottom wall 1341.

[0068] In this way, when unfolding or folding in the at least two collecting elements 134, the two adjacent collecting elements 134 can always be hooked together, thus preventing the two adjacent collecting elements 134 from separating from each other in the unfolded state and limiting the end positions of the two adjacent collecting elements 134 in the folded state.

[0069] As can be seen from Fig. As shown in section 4, in some embodiments of the application, the collecting mechanism 130 further comprises a drive arrangement 133 which is mounted on the holder 131 and serves to set the second end 1322 in motion in the first direction X.

[0070] By providing the drive arrangement 133, the unfolding or folding in of the at least two collection elements 134 can be achieved automatically, thereby enabling a switching of the collection device 132 between the collection state and the avoidance state.

[0071] In another embodiment, the second end 1322 can also be moved manually.

[0072] As in Fig. As shown in Figure 4, the drive arrangement 133 in some embodiments of the application comprises a drive element 1331, a sliding plate 1332, and a gear arrangement 1333. The drive element 1331 is mounted on the holder 131. The sliding plate 1332 is connected to the second end 1322 and is slidably fitted to the holder 131 in the first direction X. The sliding plate 1332 is connected to an output end of the drive element 1331 via the gear arrangement 1333.

[0073] In detail, in the second direction Y, the two ends of the sliding plate 1332 are each slidably fitted to the associated sliding groove. The sliding plate 1332 is mounted via a threaded element to the respective receiving element 134, which forms the second end 1322. The drive element 1331 is mounted on the associated mounting plate 1313 of the first end 1321. Via the gear arrangement 1333, the drive element 1331 sets the sliding plate 1332 in motion in the first direction X, thereby setting the respective receiving element 134, which forms the second end 1322, in motion and thus achieving the folding out or folding in of the at least two receiving elements 134.

[0074] As can be seen from Fig. As shown in Figure 4, the drive element 1331, as an exemplary embodiment, is an electric motor, and the transmission assembly 1333 comprises a drive shaft 1336, a drive wheel 1335, a driven shaft, a drive belt 1334, and a press block 1337. The drive shaft 1336 and the driven shaft are arranged side by side on two mounting plates 1313 in the first direction X. The drive element 1331 and the drive shaft 1336 are arranged on the same mounting plate 1313, and the drive element 1331 serves to rotate the drive shaft 1336. Two drive belts 1334 are provided. The two drive belts 1334 are spaced apart from each other in the second direction Y. The drive shaft 1336 and the driven shaft together support the drive belts 1334.One end of the drive belt 1334 is rotatably connected to the drive shaft 1336 via a drive wheel 1335, and the other end is driven by the other drive wheel 1335 and connected to the driven shaft. The press block 1337 is mounted on the drive belt 1334. The press block 1337 is connected to one end of the sliding plate 1332. The press blocks 1337 on the two drive belts 1334 together set the sliding plate 1332 in motion in the first direction X, starting from both ends of the sliding plate 1332.

[0075] In another embodiment, the gear arrangement 1333 can also be designed differently. The drive arrangement 133 can also be a linear drive of another type, for example a pneumatic cylinder, a chain mechanism, etc.

[0076] In some embodiments of the application, the projection of the vacuum port 1214 in the vertical direction falls into the collecting device 132 when the collecting device 132 is in the collecting state. The projection of the vacuum port 1214 in the vertical direction does not overlap with the collecting device 132 at all when the collecting device 132 is in the retraction state.

[0077] Based on the embodiment in which the vertical direction is the third direction Z and the first direction X, the second direction Y, and the third direction Z are perpendicular or nearly perpendicular to each other, the vertical projection of the vacuum port 1214 refers to the projection of the cross-section of the inner opening of the vacuum port 1214 onto the XY plane. When the collecting device 132 is in the collecting state, the vertical projection of the collecting device 132 refers to a common projection of the bottom walls 1341 of the multiple collecting elements 134 onto the XY plane.

[0078] As in Fig. As shown in Figure 1, in some embodiments of the application the vacuum formation system 100 further comprises a probe arrangement 140. The probe arrangement 140 is located at least partially below the battery storage area 111.

[0079] Depending on the design feature of the vacuum formation system 100, the probe arrangement 140 can be located completely below the battery storage area 111 or partially below the battery storage area 111.

[0080] In this way, when the collection device 132 is in the collection state, the electrolyte cannot drip onto the probe arrangement 140, which is located at least partially under the battery storage area 111, and thus corrosion of the probe arrangement 140 can be avoided.

[0081] Since the vacuum formation plant 100 according to the embodiments of the application has the collecting device 132 and the collecting device 132 can be switched between the collecting state and the escape state, the risk of corrosion of another mechanism and injury to an operator from dripping electrolyte can be reduced, so that the vacuum formation plant 100 is characterized by a long service life and good safety performance.

[0082] Finally, it should be noted that the above embodiments serve only to illustrate the technical solutions of the present application without limiting them. Although the present application is described in detail with reference to the above embodiments, the person skilled in the art should understand that he or she may modify the technical solutions described in the above embodiments or replace some or all of the technical features contained therein with equivalent ones; and that such modifications or replacements, however, do not result in the essence of the respective technical solutions differing from the scope of the technical solutions of the individual embodiments of the present application.
