[0029] In order to solve the problem that the embossing device in the prior art is separately provided with a complex adjustment structure, resulting in a complex overall structure of the embossing device, inconvenient operation and the need for repeated adjustment, this embodiment provides an embossing device for embossing a battery tab.

[0030] like Figures 1 to 5 As shown, the embossing device includes a frame 10, an embossing roller 20, a driving member and an elastic member 30. The embossing roller 20 is movably arranged on the frame 10. Two embossing rollers 20 are arranged, and the axes of the two embossing rollers 20 are parallel. The two embossing rollers 20 are used to form an embossing structure on the pole ear located between the two embossing rollers 20. The driving member is arranged on the frame 10, and the driving member is connected to one of the embossing rollers 20 for driving the embossing roller 20 to rotate. The elastic member 30 connects the two embossing rollers 20, and the elastic member 30 is used to provide a force for the two embossing rollers 20 to form an embossing structure on the pole ear.

[0031] Specifically, the embossing device of the present application adopts an elastic member 30 connected between two embossing rollers 20, and the elastic member 30 is used to provide the required force for the two embossing rollers 20 to form an embossing structure on the pole lug, so as to be suitable for the embossing roller 20 to perform embossing operation on the pole lug. The structural setting of the elastic member 30 does not require an additional adjustment structure, and the overall structure of the present application is simple; and the elastic member 30 always provides a force for the embossing roller 20 to press the pole lug, and the elastic member 30 can be selected and replaced according to the embossing force required by the thickness of the pole lug, etc., without repeated debugging, which is conducive to improving the convenience of operation and improving production efficiency.

[0032] Furthermore, the driving member provides driving force for the rotation of the embossing roller 20, and the driving member can be a power mechanism such as a motor or a rotary cylinder, and the driving member is fixedly connected to the frame 10. The driving member can be connected to the two embossing rollers 20 at the same time to provide driving force for the two embossing rollers 20 at the same time, or the driving member can be connected to one embossing roller 20 to drive the rotation of another embossing roller 20 (i.e., as a driven embossing roller) through the rotation of one embossing roller 20 (i.e., as an active embossing roller), or two driving sub-elements can be provided in the driving member, which are connected to the two embossing rollers 20 respectively to drive the embossing rollers 20 to rotate.

[0033] In this embodiment, the elastic member 30 is a tension spring, and the elastic member 30 provides a pulling force for the two embossing rollers 20 to approach each other. In the process of embossing the tab, under the action of the pulling force of the elastic member 30, the two embossing rollers 20 press the tab tightly and rotate under the driving action of the driving member to realize the embossing operation of the tab.

[0034] like Figures 1 to 5 As shown, the embossing roller 20 has mounting structures 203 at both ends along the axial direction, and an elastic member 30 is connected between the mounting structures 203 on the same side of the two embossing rollers 20 .

[0035] Among them, the elastic member 30 is connected to the embossing roller 20 through the mounting structure 203. The elastic member 30 is arranged on the same side of the two embossing rollers 20, that is, the two ends of the two embossing rollers 20 are connected by two elastic members 30 respectively, which is beneficial to improving the working efficiency of the embossing roller 20, and also conveniently improves the stability of the force between the two embossing rollers 20, thereby improving the stability of the embossing work.

[0036] Furthermore, the mounting structure 203 is an annular groove, and hooks are provided at both ends of the elastic member 30 . The hooks at both ends of the elastic member 30 are respectively hung inside two annular grooves provided on the same side of the two embossing rollers 20 .

[0037] Wherein, annular grooves are arranged at both ends of the embossing roller 20 , and the hooks of the elastic member 30 can be hooked inside the annular grooves to achieve the connection between the elastic member 30 and the embossing roller 20 .

[0038] In this embodiment, one of the two embossing rollers 20 is an active embossing roller 210, and the other is a driven embossing roller 220, and the driving member is connected to the active embossing roller 210. The driving member drives the active embossing roller 210 to rotate, thereby driving the pole ear to move, and then drives the driven embossing roller 220 to rotate, so that the active embossing roller 210 drives the driven embossing roller 220 to rotate through the pole ear. Preferably, the driven embossing roller 220 is arranged above the active embossing roller 210, and the active embossing roller 210 plays the role of supporting the pole ear. In other embodiments, the active embossing roller 210 and the driven embossing roller 220 can also be connected by a transmission assembly (such as gears, etc.), and the rotation of the driven embossing roller 220 is directly driven by the rotation of the active embossing roller 210. The movement of the pole ear can also be transmitted by another transmission device. This is all prior art and is not limited here.

[0039] like Figure 1 and Figure 2As shown, the frame 10 has two guide grooves 1211 arranged in pairs along the axial direction of the driven embossing roller 220, and at least a part of the two ends of the driven embossing roller 220 is slidably and rotatably arranged inside the guide grooves 1211. The driven embossing roller 220 can move toward or away from the active embossing roller 210 along the length direction of the guide grooves 1211.

[0040] Specifically, the driven embossing roller 220 can move along the length direction of the guide groove 1211, thereby adjusting the relative distance between the active embossing roller 210 and the driven embossing roller 220, so as to be suitable for embossing the tabs of different thicknesses. The structural setting of the guide groove 1211 not only enables the driven embossing roller 220 to move toward or away from the active embossing roller 210, but also enables the driven embossing roller 220 to be rotatably arranged on the frame 10, and the guide groove 1211 has the technical effects of guidance and installation.

[0041] Furthermore, the frame 10 includes a panel 110 and a bracket 120, the driving member is arranged on the panel 110, the bracket 120 is fixedly arranged on the panel 110, the bracket 120 extends in the same direction as the axis of the driven embossing roller 220, and both ends of the bracket 120 have mounting plates 121 extending toward one side of the active embossing roller 210, and the mounting plates 121 have guide grooves 1211, and the driven embossing roller 220 is movably arranged on the mounting plates 121 through the guide grooves 1211.

[0042] Among them, the panel 110 and the bracket 120 are used to provide an installation position. The bracket 120 has a mounting plate 121. The mounting plate 121 is provided with a guide groove 1211 for installing the driven embossing roller 220. The mounting plate 121 structure extending toward the active embossing roller 210 is convenient for forming the guide groove 1211, thereby facilitating the movement of the driven embossing roller 220 toward or away from the active embossing roller 210.

[0043] In this embodiment, the following two implementation modes are provided according to the different structures of the connection between the driven embossing roller 220 and the guide groove 1211.

[0044] like Figure 1 and Figure 2 In the specific embodiment shown, the embossing device also includes a sliding member 40, which is detachably arranged at both ends of the driven embossing roller 220, one end of the sliding member 40 is limitedly abutted against the mounting plate 121, and the other end of the sliding member 40 passes through the guide groove 1211 and is connected to the driven embossing roller 220.

[0045] In this embodiment, the part of the sliding member 40 located inside the guide groove 1211 can move along the length direction of the guide groove 1211, and when the driven embossing roller 220 rotates, the sliding member 40 can rotate accordingly, that is, the sliding member 40 can rotate inside the guide groove 1211. The sliding member 40 also has the technical effect of preventing the sliding member 40 from falling off. The end of the sliding member 40 away from the driven embossing roller 220 abuts against the bracket 120 to limit the position, thereby preventing the driven embossing roller 220 from falling off and being misplaced. The sliding member 40 is easy to disassemble and assemble, and is simple to operate.

[0046] In a specific embodiment not shown in the figure, the driven embossing roller 220 has protrusions at both ends, and the protrusions extend along the axial direction of the driven embossing roller 220. At least a portion of the protrusions extends into the interior of the guide groove 1211, and the protrusions are slidably and rotatably arranged inside the guide groove 1211.

[0047] In this embodiment, the boss is rotatable inside the guide groove 1211 and can move along the length direction of the guide groove 1211. The boss is a part of the driven embossing roller 220, which is beneficial to improving the overall installation strength and overall stability.

[0048] like Figure 3 As shown, the embossing roller 20 has an embossing section 201 and an adjusting section 202 along its axial direction. The embossing device also includes an adjusting structure, which is detachably arranged on the adjusting section 202 and is used to adjust the distance between the two embossing rollers 20 .

[0049] Specifically, the embossing roller 20 of the present application has an embossing section 201 and an adjustment section 202. The distance between the two embossing rollers 20 can be adjusted by setting the adjustment structure, that is, the distance between the two embossing sections 201 can be adjusted, thereby facilitating adaptation to the embossing requirements of different tabs.

[0050] The embossing roller 20 has an embossing section 201 and an adjusting section 202 , so that the adjusting section 202 can provide an installation position for the adjusting structure, thereby adjusting the distance between the two embossing sections 201 through the adjusting structure at the adjusting section 202 .

[0051] Furthermore, the adjustment structure is a Teflon gasket, which is bonded to the outer surface of the adjustment section 202. The distance between the two embossing rollers 20 is adjusted by adjusting the number of layers or thickness of the Teflon gasket.

[0052] The present application adopts a Teflon gasket bonded to the adjustment section 202 as the adjustment structure, which is convenient for operation.

[0053] In this embodiment, the embossing section 201 of one of the two embossing rollers 20 has a circumferentially arranged protrusion structure, and the embossing section 201 of the other embossing roller 20 has a groove structure adapted to the protrusion structure. There are multiple protrusion structures, and the multiple protrusion structures are arranged along the circumference of the embossing roller 20. The protrusion structure is adapted to the groove structure, so that the pole ear located at the embossing section 201 is embossed.
