Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0034] refer to Figures 1 to 5 , an embodiment of the present application provides an electrode sheet stacking auxiliary mechanism 100. The electrode sheet stacking auxiliary mechanism 100 includes: a stacking platform 110, a limiting component 120 and a lifting component 130. Among them, the stacking platform 110 is used to carry electrode sheets. The limiting component 120 includes a first limiting component 121 and a second limiting component 122 that are opposite to each other along a first direction X, and the first limiting component 121 and / or the second limiting component 122 are movably connected to the stacking platform 110 and can approach or move away from each other along the first direction X relative to the stacking platform 110, and the electrode sheet is configured to be stacked between the first limiting component 121 and the second limiting component 122. The lifting component 130 is arranged on the stacking platform 110 to lift the electrode sheet along a third direction Z.

[0035] The electrode sheet stacking auxiliary mechanism 100 provided in the embodiment of the present application has the first limiting component 121 and the second limiting component 122 of the limiting assembly 120 approaching each other during the electrode sheet stacking process, and can adjust the position and align the electrode sheet placed therebetween, thereby effectively improving the quality of the electrode sheet stacking. At the same time, by setting up a lifting mechanism, it is easy to clamp the stacked electrode sheets, which is beneficial to the subsequent use of the electrode sheets or the implementation of other production processes.

[0036] Specifically, during the electrode sheet stacking assisting mechanism 100 assists in stacking the electrode sheets, the electrode sheets are stacked between the first limiting component 121 and the second limiting component 122. When the electrode sheet is deflected along the first direction XX, the first limiting component 121 and the second limiting component 122 can approach each other along the direction, and then move toward the electrode sheet to push the deflected electrode sheet, so that the deflection amount is eliminated or reduced to a controllable range.

[0037] Optionally, the first limiting component 121 may be directly movably connected to the stacking platform 110, or may be movably connected to the stacking platform 110 through other components. As an example, when the first limiting component 121 is directly movably connected to the stacking platform 110, a slideway is provided on the stacking platform 110, the slideway is recessed relative to the support plane of the stacking platform 110 and extends along the first direction X, and part of the first limiting component 121 is inserted into the slideway and can move along the first direction X in the slideway; as another example, when the first limiting component 121 is movably connected to the stacking platform 110 through other components, a slide rail assembly extending along the first direction X is provided on the stacking platform 110, and the first limiting component 121 is connected to the slide rail assembly and can move along the first direction X relative to the stacking platform 110. Optionally, the second limiting component 122 may be movably connected to the stacking platform 110 and can move along the first direction XX relative to the stacking platform 110, and the second limiting component 122 may also be fixedly connected to the stacking platform 110. As an example, when the second limiting component 122 is fixedly connected to the stacking platform 110 , the second limiting component 122 may be disposed on a side of the electrode sheet where no electrode tab is disposed, so as to reduce impact damage to the electrode tab.

[0038] Optionally, the first limiting component 121 and the second limiting component 122 may be made of, but are not limited to, metal or non-metal materials, for example, the metal material may be copper, copper alloy, aluminum, aluminum alloy, nickel, nickel alloy, titanium, titanium alloy or stainless steel, etc., and the non-metal material may be polyethylene, polypropylene, polyvinyl chloride or wood, etc. As an example, the first limiting component 12121 and the second limiting component 12222 are made of the same material to simplify the preparation process and help reduce costs.

[0039] The above technical solution sets the limit assembly 120 , and during the electrode sheet stacking process of the electrode sheet stacking auxiliary mechanism 100 , the limit assembly 120 can correct the deflected electrode sheet, thereby effectively improving the electrode sheet stacking quality of the electrode sheet stacking auxiliary mechanism 100 .

[0040] In a possible implementation, Figure 1 and Figure 2As shown, a first groove 111 is provided on the stacking platform 110 along the first direction X. The first groove 111 is recessed relative to the surface of one side of the stacking platform 110 close to the limiting assembly 120, and part of the first limiting component 121 is accommodated in the first groove 111 and slides in the first groove 111 along the first direction X. The side wall of the first groove 111 close to one end of the second limiting component 122 along the first direction X is used to limit the displacement of the first limiting component 121. By providing the first groove 111 structure for the sliding track of the first limiting component 121, on the one hand, the movement of the first limiting component 121 along the first direction X can be guided, and on the other hand, the first limiting component 121 can be limited or fixed to prevent the first limiting component 121 from sliding off or slipping off the stacking platform 110. At the same time, the side wall of the first groove 111 close to one end of the second limiting component 122 along the first direction X can limit the displacement of the first limiting component 121 along the first direction X to prevent the risk of damage to the electrode sheet caused by extrusion due to excessive movement.

[0041] In a feasible implementation, a third groove 113 is further provided on the stacking platform 110. The third groove 113 is arranged parallel to the first groove 111. At the same time, the length direction of the first limiting component 121 is arranged along the second direction Y, and the first limiting component 121 is partially accommodated in the third groove 113. In this way, the stability of the first limiting component 121 moving along the first direction X can be improved, and the increase in the length of the first limiting component 121 can also increase the force application area during the correction process of the electrode sheet, thereby improving the correction effect.

[0042] In a possible implementation, Figure 1 As shown, the limiting assembly 120 also includes a driving assembly 123. The driving assembly 123 is connected to the limiting assembly 120 of the first limiting component 121, and is used to drive the first limiting component 121 to approach or move away from the second limiting component 122 along the first direction X. Optionally, the driving assembly 123 can be a common electric driving device, such as a stepper motor drive, a servo motor drive, a DC or AC motor drive, etc. It can also be a hydraulic drive device, a pneumatic drive device, a hybrid drive device drive, etc. The driving assembly 123 can also be a mechanical transmission device, such as a power transmission drive method such as a gear drive, a belt drive or a chain drive. In some cases, the limiting assembly 120 may also not include the driving assembly 123, and the operator directly drives the first limiting component 121 and / or the second limiting component 122 to move.

[0043] In a feasible implementation, the driving assembly 123 is arranged on one side of the first limiting component 121 along the second direction Y. The driving assembly 123 includes a push rod 1231 and a first connecting rod 1232, one end of the first connecting rod 1232 along the second direction Y is connected to the output end of the push rod 1231, and the other end of the first connecting rod 1232 along the second direction Y is connected to the first limiting component 121. Moving the push rod 1231 along the second direction Y can drive the first limiting component 121 to approach or move away from the second limiting component 120 along the first direction X. In this way, the push rod 1231 can be manipulated by a simple mechanical structure to achieve the movement of the first limiting component 121. Exemplarily, a wedge-shaped structure can be connected between the push rod 1231 and the first connecting rod 1232, so that the push rod 1231 can move along the second direction Y and the connecting rod can drive the first limiting component 121 to move along the first direction X. Exemplarily, the first connecting rod 1232 and the first limiting component 121 may be connected via a hinge, and the push rod 1231 and the first limiting component 121 may be arranged in parallel and not in a straight line on the stacking platform 110, and the above effect may also be achieved via a hinge connection.

[0044] In a possible implementation, Figure 1As shown, the first limiting component 121 and the second limiting component 122 are symmetrically arranged on the stacking platform 110 along the axial direction of the push rod 1231. The stacking platform 110 is also provided with a second groove 112, which is symmetrically arranged with the first groove 111 along the axial direction of the push rod 1231 on the stacking platform 110, and the second limiting component 122 is partially accommodated in the second groove 112. The driving assembly 123 also includes a second connecting rod 1233, which is symmetrically arranged with the first connecting rod 1232 along the axial direction of the push rod 1231 on the stacking platform 110, and one end of the second connecting rod 1233 is fixedly connected to the second limiting part, and the other end is connected to the push rod 1231. In this way, pushing and pulling the push rod 1231 can make the first limiting component 121 and the second limiting component 122 approach or move away from each other at the same time, so that the electrode sheet can be kept centered during the stacking process, which can facilitate the implementation of the subsequent access operation. For example, if a robot is picking up an item, a good positioning effect can be achieved. At the same time, the simultaneous movement of the first limiting component 121 and the second limiting component 122 can perform bidirectional correction, reduce the displacement of the electrode sheet correction, and avoid the risk of damage caused by excessive position deviation movement. Exemplarily, the second connecting rod 1233 has the same structure as the first connecting rod 1232, and the push rod 1231 can be a wedge-shaped structure with two symmetrically arranged away from each other. For example, a trapezoid or a triangle, so that the push rod 1231 can move along the second direction Y and drive the first connecting rod 1232 and the second connecting rod 1233 to move along the first direction X.

[0045] Furthermore, if Figure 1 As shown, hinge connections are adopted between the first connecting rod 1232 and the first position-limiting component 121, between the second connecting rod 1233 and the second position-limiting component 122, and between the first connecting rod 1232, the second connecting rod 1233 and the push rod 1231. The hinge connection enables the first position-limiting component 121 and the second position-limiting component 122 to move smoothly in the first groove 111, and the connection is reliable, the structure is simple, the processing technology is simple, and it is easy to implement.

[0046] In a possible implementation, Figure 1 and Figure 2As shown, a short column 114 is provided on the stacking platform 110. The short column 114 has a first through hole 1141 along the second direction Y, and a thread is provided in the first through hole 1141. The push rod 1231 has a thread, and the push rod 1231 passes through the first through hole 1141 and is threadedly connected to the short column 114. On the one hand, the push rod 1231 can be fixed to the stacking platform 110 by providing the short column 114, and can also play a role of limiting and guiding. On the other hand, through the tight engagement of the internal and external threads, a strong axial and radial fixing force is provided to ensure the stability and reliability of the connection; the threaded connection also allows the relative positions between the components to be accurately adjusted and fixed. At the same time, the threaded connection can also realize the reciprocating motion of the push rod 1231 in the second direction Y, and the structure is simple and easy to implement.

[0047] In a feasible implementation, a handle 1234 may be installed at the portion of one end of the push rod 1231 extending out of the side wall of the stacking platform 110. Rotating the handle 1234 may drive the push rod 1231 to rotate and move along the second direction Y, thereby driving the first connecting rod 1232 and the second connecting rod 1233 to drive the first limiting component 121 and the second limiting component 122 to move. The handle 1234 may facilitate the operator to hold and operate, thereby improving the comfort and fluency of use.

[0048] In a possible implementation, Figure 1 and Figure 2 As shown, a second through hole 115 is provided on the stacking platform 110 along the third direction Z. The lifting assembly 130 shown includes a lifting rod 131, a lifting plate 132 and a lifting drive mechanism 133. The lifting plate 132 is arranged parallel to the stacking platform 110. The lifting rod 131 passes through the second through hole 115 and connects the lifting plate 132 with the lifting drive mechanism 133. The lifting drive mechanism 133 is fixed below the stacking platform 110. The lifting rod 131 drives the lifting plate 132 to move along the third direction Z under the drive of the lifting drive mechanism 133.

[0049] In a feasible implementation, the lifting assembly 130 may also be other structural forms arranged on the stacking platform 110. For example, a forklift may be arranged on the stacking platform 110, and the fork may lift the stacked electrode sheets as a whole. For another example, the stacking platform 110 may be moved as a whole in the third direction Z.

[0050] In a feasible implementation, the lifting rod 131 and the lifting drive mechanism 133 may be a screw lifting structure, a rack lifting structure, a hydraulic lifting structure or other common motor lifting, etc. As an example, the lifting rod 131 and the lifting drive mechanism 133 may be a rack lifting structure.

[0051] In a possible implementation, Figure 4 and Figure 5 As shown, the lifting drive mechanism 133 includes a driving gear 1331, which is rotatably arranged below the stacking platform 110, and the lifting rod 131 is meshed with the driving gear 1331 in the third direction Z. The meshing structure of the rack and the gear provides good stability, the meshing lifting contact area is large, the structure is solid, and it can carry a heavier load, which is suitable for lifting heavy equipment or structures; using high-quality materials and designs, the meshing lifting usually has a longer service life, reducing the frequency of replacement and maintenance; the length of the rack can be customized according to actual needs, which enables this type of mechanism to flexibly adapt to various working conditions and is conducive to a wide range of applications; the meshing lifting usually adopts gear transmission, which is simpler to maintain and has lower costs than other complex systems; the rolling friction design method is adopted to reduce noise and vibration during operation, and has less impact on the surrounding environment and operators. The meshing lifting requires a small space, which is conducive to spatial layout; the rack lifting is stable, easy to control and accurately adjusted.

[0052] Furthermore, the power source of the driving gear 1331 can be human power, electric power, hydraulic power, etc.

[0053] In a feasible implementation manner, the lifting rod 131 has a limiting portion (not shown) at one end away from the lifting plate 132 , and the limiting portion is used to limit the displacement of the lifting rod 131 driven by the driving gear 1331 along the third direction Z.

[0054] In a possible implementation, Figure 4 and Figure 5 As shown, the lifting drive mechanism 133 also includes a long shaft 1332, which is arranged below the stacking platform 110 and fixedly connected to the stacking platform 110, and the driving gear 1331 is sleeved on the long shaft 1332 and fixedly connected to the long shaft 1332, and the long shaft 1332 can rotate around the axis and drive the driving gear 1331 to rotate.

[0055] Furthermore, the driving gear 1331 and the long shaft 1332 can be fixedly connected by welding, riveting, screwing of the shaft and bearing, flange connection or interference fit. As an example, the driving gear 1331 and the long shaft 1332 can be fixedly connected by interference fit. Interference fit does not require additional fasteners, simplifies the design and assembly process, and reduces the number of parts; because the interference fit can ensure a tight fit between the shaft and the hole, it has excellent coaxiality and centration, which helps to improve rotation accuracy and reduce operating noise; the interference fit can transmit greater torque and axial force; the interference fit can better resist impact loads and improve the stability and reliability of the system.

[0056] Further, the long axis 1332 is arranged below the stacking platform 110 along the first direction X. The side wall below the stacking platform 110 may be provided with a third through hole 116, and the long axis 1332 is arranged to pass through the third through hole 116. A knob 1333 may be installed on the portion of the long axis 1332 that extends out of the side wall of the stacking platform 110. Rotating the knob 1333 may drive the driving gear 1331 to rotate, thereby driving the lifting plate 132 to rise and fall. The knob 1333 may be convenient for the operator to hold and operate, thereby improving the comfort and fluency of use.

[0057] Furthermore, if Figure 3 As shown, a support assembly can be fixed below the stacking platform 110, and the support assembly is used to carry the jacking drive mechanism 133. The support assembly includes a support plate and a connecting plate. The support plate is connected to the two side walls of the stacking platform 110 along the first direction X. The connecting plate is arranged along the third direction Z, one end of which is connected to the long axis 1332 and the other end is fixed to the support plate. A through hole is provided at one end of the connecting plate connected to the long axis 1332, and the long axis 1332 is rotatably fixed to the connecting plate.

[0058] The operation process of the electrode sheet stacking auxiliary mechanism 100 provided in the present application is as follows:

[0059] Rotate the knob 1333, and the long shaft 1332 rotates synchronously to drive the driving gear 1331 to drive the lifting plate 132 to move along the third direction Z until the lifting plate 132 is lowered to the same plane as the stacking platform 110 or lower than the upper surface of the stacking platform 110;

[0060] The handle 1234 is rotated, and the push rod 1231 rotates synchronously to drive the first connecting rod 1232 and the second connecting rod 1233 to drive the first limiting component 121 and the second limiting component 122 to move away from each other, until the target electrode sheet can be accommodated between the first limiting component 121 and the second limiting component 122;

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
