A mounting reference surface is provided on the gantry 130, and the first roller 110 and the second roller 120 are both abutted on the mounting reference surface, so that the first roller 110 and the second roller 120 are collinear in the second direction, i.e., the X-direction, and the installation accuracy in the X-direction is improved. An adjustment component 150 is provided between the first roller 110 and the second roller 120, and the adjustment component 150 is used to adjust the gap between the first roller 110 and the second roller 120, so as to adjust the gap between the first roller 110 and the second roller 120 in the Y-direction, thereby ensuring the parallelism of the first roller 110 and the second roller 120 in the X- and Y-directions.

The first base plate 131, the first side plate 133, the second base plate 132 and the second side plate 134 are connected in sequence to form a frame structure. One end of the first roller 110 is connected to the first side plate 133, and the other end is connected to the second side plate 134. One end of the second roller 120 is slidably connected to the first side plate 133, and the other end is slidably connected to the second side plate 134.

[0040] Optionally, a first guide hole 135 is formed on the first side plate 133, and a second guide hole 136 is formed on the second side plate 134; the installation reference surface includes a first reference surface and a second reference surface arranged in the same plane, the first reference surface is arranged on the hole wall of the first guide hole 135, and the second reference surface is arranged on the hole wall of the second guide hole 136. In this embodiment, the first guide hole 135 and the second guide hole 136 are rectangular holes respectively, and the inner walls of the rectangular holes include a first side wall 101 and a second side wall 102 arranged oppositely and a third side wall 103 and a fourth side wall 104 arranged oppositely, wherein the first side wall 101 is close to the first substrate 131, the second side wall 102 is close to the second substrate 132, and the third side wall 103 or the fourth side wall 104 serves as the installation reference surface. One end of the first roller 110 is arranged in the first guide hole 135 and abuts against the first reference surface, and the other end is arranged in the second guide hole 136 and abuts against the second reference surface. One end of the second roller 120 is disposed in the first guide hole 135 and abuts against the first reference surface, and the other end is disposed in the second guide hole 136 and abuts against the second reference surface, and the second roller 120 can move along the first reference surface and the second reference surface. Through the installation reference surface on the gantry 130, the first roller 110 and the second roller 120 are collinear in the second direction, i.e., the X direction, thereby improving the installation accuracy in the X direction.

[0041] Furthermore, a bearing mounting seat is provided at both ends of the first roller 110, and the bearing mounting seat is connected to the first side plate 133 and the second side plate 134, respectively. A first tapered roller bearing 112 is arranged in the bearing mounting seat, and the first roller 110 is supported by the first tapered roller bearing 112, and a first axial fixing member 111 is arranged at one end of the first tapered roller bearing 112 away from the middle of the first roller 110, so as to achieve axial preload and prevent axial movement. Similarly, a bearing mounting seat is provided at both ends of the second roller 120, and the bearing mounting seat is connected to the first side plate 133 and the second side plate 134, respectively. A second tapered roller bearing 122 is arranged in the bearing mounting seat, and the second roller 120 is supported by the second tapered roller bearing 122, and a second axial fixing member 121 is arranged at one end of the second tapered roller bearing 122 away from the middle of the second roller 120, so as to achieve axial preload and prevent axial movement. In this embodiment, the first axial fixing member 111 adopts a locking nut, and the second axial fixing member 121 adopts a locking nut. The locking nuts are respectively sleeved on both ends of the first roller 110 and the second roller 120 to axially pre-tighten the first roller 110 and the second roller 120 to prevent axial movement of the first roller 110 and the second roller 120 and improve the installation accuracy in the Z direction.

[0042] Please refer to Figure 4 and Figure 5 , an adjustment assembly 150 is respectively installed on the first side plate 133 and the second side plate 134, and the adjustment assembly 150 is located between the first roller 110 and the second roller 120. Optionally, the adjustment assembly 150 is connected to the second roller 120, and can drive the second roller 120 to move away from or close to the first roller 110, so as to adjust the gap between the first roller 110 and the second roller 120, that is, the adjustment in the Y direction. In this embodiment, the third side wall 103 and the fourth side wall 104 in the first guide hole 135 and the second guide hole 136 also serve as guide surfaces for the second roller 120 to move in the Y direction, which is conducive to improving the adjustment accuracy.

[0043] Each adjustment assembly 150 includes a mounting seat 151, a first wedge block 152, a second wedge block 153 and an adjusting member 156. The mounting seat 151 is fixed on the first side plate 133 or the second side plate 134. The adjusting member 156 is connected to the first wedge block 152 or the second wedge block 153. The first wedge block 152 is connected to the mounting seat 151. One end of the second wedge block 153 is connected to the first wedge block 152, and the other end is in contact with the second roller 120. The adjusting member 156 can make the second wedge block 153 move relative to the first wedge block 152. Furthermore, a first inclined surface 154 is provided at one end of the first wedge block 152 away from the mounting seat 151, and a second inclined surface 155 matched with the first inclined surface 154 is provided at one end of the second wedge block 153 close to the first wedge block 152. The first inclined surface 154 and the second inclined surface 155 can move relative to each other under the drive of the adjusting member 156 to adjust the position of the second wedge block 153. In this embodiment, the first wedge block 152 is connected to the mounting seat 151, and the adjusting member 156 is connected to the first wedge block 152. The adjusting member 156 is provided with an external thread, and the first wedge block 152 is provided with an internal thread corresponding to the external thread. The rotation of the adjusting member 156 can drive the first wedge block 152 to move axially along the adjusting member 156, that is, the first wedge block 152 moves along the second inclined surface 155 of the second wedge block 153 to change the height position of the second wedge block 153, and then change the height of the second roller 120, that is, the gap width between the first roller 110 and the second roller 120 can be adjusted.

[0044] Optionally, if the adjusting member 156 is rotated counterclockwise, the first wedge block 152 moves to the right along the axial direction of the adjusting member 156, and the second wedge block 153 moves downward along the first inclined surface 154 of the first wedge block 152 under the action of the gravity of the second roller 120, so that the second roller 120 moves in a direction close to the first roller 110, that is, the gap between the first roller 110 and the second roller 120 is adjusted to be smaller. Similarly, if the adjusting member 156 is rotated clockwise, the first wedge block 152 moves to the left along the axial direction of the adjusting member 156, and the second wedge block 153 is pushed upward, that is, the second wedge block 153 moves upward relative to the first inclined surface 154 of the first wedge block 152, so that the second roller 120 moves in a direction away from the first roller 110, that is, the gap between the first roller 110 and the second roller 120 is adjusted to be larger. The terms "up", "down", "left" and "right" herein are only used in the sense of the upper, lower, left and right directions. Figure 5 From the perspective shown.

[0045] In other embodiments, the adjusting member 156 may also be a screw, which abuts against the second wedge block 153. By rotating the screw, the second wedge block 153 may be driven to move left and right relative to the first inclined surface 154, thereby achieving the lifting and lowering of the second roller 120. Of course, it is not limited to this. The adjusting member 156 may also be other structural forms. For example, the second wedge block 153 moves directly under the action of an external force. Optionally, the second wedge block 153 may also be connected to a cylinder, and the second wedge block 153 moves along the first inclined surface 154 by the driving force of the cylinder. All of these are feasible and are not specifically limited here.

[0046] Furthermore, a measuring instrument 160 is provided on the gantry 130, and the measuring instrument 160 is used to measure the gap width between the first roller 110 and the second roller 120. In this embodiment, the measuring instrument 160 adopts a micrometer, and the number of micrometers can be two, which are respectively arranged at both ends of the second roller 120, so as to make the gaps adjusted at both ends of the second roller 120 consistent, and improve the parallelism of the first roller 110 and the second roller 120.

[0047] The pressure device 140 is disposed on the gantry 130 and connected to the second roller 120. The pressure device 140 is used to apply pressure to the second roller 120. In this embodiment, the pressure device 140 adopts a cylinder, and the cylinder directly applies pressure toward the first roller 110 to the second roller 120, so that the composite product has a stable pressing effect when passing through the gap between the first roller 110 and the second roller 120. Optionally, the number of pressure devices 140 is two, which are respectively arranged at both ends of the second substrate 132. Two mounting holes are provided on the second substrate 132 for the force rod of the pressure device 140 to pass through. The force rod of the pressure device 140 passes through the mounting hole and is connected to the second roller 120. The two pressure devices 140 work simultaneously, so that the forces at both ends of the second roller 120 are evenly applied, thereby improving the pressing quality. Of course, in other optional embodiments, the number of pressure devices 140 can also be one, and the force rod acts on the middle of the second roller 120; or, the number of pressure devices 140 can also be three or more, and the force rods are evenly distributed on the second roller 120, and the pressure distribution is more uniform.

[0048] According to a gantry type composite roller 100 provided in this embodiment, its working principle is as follows:

[0049] The first roller 110 and the second roller 120 are mounted on the gantry 130. The overall structure of the gantry 130 has good rigidity, strong bearing capacity, and a stable and reliable structure. The first roller 110 is connected to a first drive motor 114, which is used to drive the first roller 110 to rotate. The second roller 120 is connected to a second drive motor 124, which is used to drive the second roller 120 to rotate. The first roller 110 and the second roller 120 are fixed to the gantry 130 using tapered roller bearings, and a first axial fixing member 111 is provided at both ends of the first roller 110, and a second axial fixing member 121 is provided at both ends of the second roller 120 to achieve axial pre-tightening, prevent the first roller 110 and the second roller 120 from moving in the Z direction, and improve the installation accuracy in the Z direction. Secondly, the first guide hole 135 and the second guide hole 136 on the gantry 130 are used as the installation reference and the guide reference by utilizing the processing coplanarity of the gantry 130. Specifically, the third side wall 103 or the fourth side wall 104 is used as the installation reference surface to ensure that the first roller 110 and the second roller 120 are collinear in the X direction, thereby improving the installation accuracy in the X direction. The third side wall 103 and the fourth side wall 104 also serve as the movement guide for the second roller 120 during the gap adjustment, thereby improving the gap adjustment accuracy in the Y direction, thereby improving the parallelism of the first roller 110 and the second roller 120 in the X and Y directions. In this embodiment, the parallelism of the first roller 110 and the second roller 120 in the X and Y directions is not greater than 0.005 mm, which solves the problem of excessive parallelism of the double rollers and unstable composite effect in the industry. At the same time, the guide reference and the installation reference surface are shared, which is convenient for processing and manufacturing, more compact in structure, and more convenient for assembly. The adjustment assembly 150 uses a first wedge block 152 and a second wedge block 153, which has a simple principle and a reliable structure, and can adjust the gap between the first roller 110 and the second roller 120 to meet various composite process requirements and improve equipment compatibility.

[0050] The first roller 110 is fixed on the gantry 130 as a reference roller. According to different process requirements, the position of the second roller 120 is adjusted by the adjustment component 150 to meet the composite gap requirements of the first roller 110 and the second roller 120, and the gap consistency between the first roller 110 and the second roller 120 can be guaranteed to be within 0.02mm. The pressure device 140 is set on the gantry 130 and connected to the second roller 120 to apply pressure to the second roller 120 to improve the lamination stability of the composite product.

[0051] In summary, the embodiment of the present invention provides a gantry type composite roller 100 and a laminating machine, which have the following beneficial effects:

[0052] A gantry-type composite roller 100 and a laminating machine provided by an embodiment of the present invention realize axial pre-tightening through a first axial fixing member 111 and a second axial fixing member 121 to prevent axial movement. By setting a mounting reference surface and a guide reference on the gantry 130, the parallelism of the first roller 110 and the second roller 120 is effectively improved, and the parallelism is controlled within 0.005 mm, and the quality of the pole piece composite is significantly improved. Secondly, an adjustment component 150 is provided between the first roller 110 and the second roller 120, which is used to adjust the gap between the first roller 110 and the second roller 120 to meet various composite process requirements, improve equipment compatibility, and have a wider range of applications.

[0053] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
