[0047] For ease of description, we define three mutually perpendicular coordinate axes in space as the X-axis, the Y-axis, and the Z-axis. The direction along the X-axis is the longitudinal direction, the direction along the Y-axis is the transverse direction, and the direction along the Z-axis is the vertical direction. The X-axis and Y-axis are two mutually perpendicular coordinate axes in the same horizontal plane, and the Z-axis is the vertical coordinate axis. The X-axis, Y-axis, and Z-axis are located in three mutually perpendicular planes in space: the XY plane, the YZ plane, and the XZ plane. The XY plane is a horizontal plane, the XZ plane and the YZ plane are both vertical planes, and the XZ plane is perpendicular to the YZ plane. The three axes in space are the X-axis, Y-axis, and Z-axis. Movement along these three axes in space refers to movement along the three mutually perpendicular axes in space, specifically movement along the X-axis, Y-axis, and Z-axis in space. Planar movement, on the other hand, refers to movement in the XY plane.

A lower stacking component 3 is provided between the first material transfer adsorption seat 72 and the second material transfer adsorption seat 73. The material transfer power unit 74 can drive the first material transfer adsorption seat 72 and the second material transfer adsorption seat 73 to be respectively close to or away from the lower stacking component 3, so that the film suction component 6 can respectively adsorb and transfer the electrode film or the protective film to the lower stacking component 3.

[0059] Optionally, the material moving power unit 74 may be a pneumatic cylinder / electric cylinder transmission mechanism, a screw transmission mechanism, a slide linear motor, etc., which is not the only limitation here.

[0060] In one embodiment, see Figure 5 The first material transfer and adsorption seat 72 is rotatably mounted with a plurality of first guide rollers 722. These first guide rollers 722 guide the first film strip from the first feeding assembly 1 to the top of the first material transfer and adsorption seat 72, facilitating subsequent film slitting. Similarly, the second material transfer and adsorption seat 73 is rotatably mounted with a plurality of second guide rollers 732. These second guide rollers 732 guide the second film strip from the second feeding assembly 2 to the top of the second material transfer and adsorption seat 73, facilitating subsequent film slitting.

[0061] In one embodiment, see Figure 1 and Figure 6, positioning holes are respectively provided at the four corners of each electrode diaphragm (not shown in the figure); the laminating machine also includes a visual positioning component 8 arranged between the first feeding component 1 and the upper laminating component 4, and the visual positioning component 8 can be arranged above the material transfer component 7. Specifically, the visual positioning component 8 includes a visual positioning bracket 81 and four camera units 82.

Among them, the camera unit 82 can be a CCD camera, etc., which is a camera commonly used on the market. This structure, through the four camera units 82 respectively aligned with the four positioning holes on the electrode diaphragm, can realize the positioning and loading of the electrode diaphragm, thereby improving the loading accuracy of the electrode diaphragm.

[0062] In one embodiment, see Figure 6 The visual positioning assembly 8 also includes a dust removal member 83 mounted on the visual positioning bracket 81. The dust removal member 83 can be installed between the four camera units 82. The dust removal member 83 is a commonly used component on the market and will not be described in detail here. This structure allows the dust removal member 83 to remove dust from the electrode membrane, thereby improving the quality of the product 100 formed by laminating multiple electrode membranes.

[0063] In one embodiment, see Figures 7 to 9 The film cutting assembly 5 includes a film cutting bracket 51, a film cutting sliding seat 52, a film cutting power unit 53, a cutter unit 54 and a cutter power unit 55. The film cutting bracket 51 can be arranged between the material moving assembly 7 and the upper stacking assembly 4. The film cutting sliding seat 52 is slidably mounted on the film cutting bracket 51. The film cutting power unit 53 is mounted on the film cutting bracket 51, and the output end of the film cutting power unit 53 is connected to the film cutting sliding seat 52, and the film cutting power unit 53 can drive the film cutting sliding seat 52 to slide back and forth. Among them, the film cutting power unit 53 can be a cylinder / electric cylinder transmission mechanism, a screw transmission mechanism, a slide linear motor, etc. The cutter unit 54 is slidably mounted on the upper stacking seat 43 of the upper stacking assembly 4, and the cutter unit 54 is used for film cutting processing.

The upper stacking seat 43 of the upper stacking assembly 4 is slidably mounted on a film cutting slide 52. With this structure, a cutter unit 54 is driven downward by a cutter power unit 55 to cut the electrode membrane or protective membrane. The film cutting slide 52 is driven by the film cutting power unit 53 to slide, allowing the cutter unit 54 and the upper stacking seat 43 to be pulled out of the stacking process, making it easier for operators to maintain the cutter unit 54 and the upper stacking seat 43.

[0064] In one embodiment, see Figure 8The cutter unit 54 comprises multiple cutter bases 541, blades 542 mounted at the bottom of each cutter base 541, and cutter guide rods 543 mounted at the top of each cutter base 541. Each cutter guide rod 543 extends through the film-cutting slide 52. Each cutter guide rod 543 is sleeved with a cutter spring (not shown).
