This allows the same lifting seat 30 to move the first positioning seat 41, the second positioning seat 42, the third positioning seat 43, and the fourth positioning seat 44 respectively via the first rotating wheel 4111, the second rotating wheel 4211, the third rotating wheel 4311, and the fourth rotating wheel 4411. This facilitates the positioning of the first positioning seat 41, the second positioning seat 42, the third positioning seat 43, and the fourth positioning seat 44 on the left, front, rear, and right sides of the lithium battery end cap on the support seat 20. This avoids the problem of multiple positioning modules being independent and unable to be positioned synchronously, improves the positioning accuracy of the positioning device 100, and ensures working efficiency.

[0048] Please refer to the attached document. Figures 1-3 7. In this embodiment of the application, the frame 10 is provided with a plurality of guide rails 15, which are respectively located at a plurality of positions on the frame 10 and connected to the corresponding positioning seats 40, so that each positioning seat 40 can move relative to the frame 10 through each guide rail 15, thereby ensuring the smooth movement of each positioning seat 40.

[0049] In a second application embodiment, a film applicator includes a positioning device 100, which is part of the film applicator, a device for precisely applying protective or decorative films to the surface of a product.

[0050] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a positioning device 100 and a film applicator. The frame 10 has a through hole 10a; a support base 20 is connected to the frame 10 and has multiple positioning grooves 20a, which are spaced apart along the width direction of the support base 20; each positioning groove 20a is used to position the lithium battery end cap; a lifting base 30 is movably connected to the frame 10 and passes through the through hole 10a; the lifting base 30 has multiple inclined surfaces 31, which are distributed at different positions and arranged along the annular direction of the lifting base 30; multiple positioning seats 40 are distributed on the outer periphery of the support base 20 and are located in different directions of the support base 20; each positioning seat 40 is movably connected to the frame 10 and moves closer to or further away from the corresponding positioning groove 20a; each positioning... The base 40 is provided with a moving body and a positioning body. The moving body is movably connected to the frame 10 and is located on the outer periphery of the through hole 10a. One end of the moving body faces the through hole 10a and contacts different positions of the inclined surface 31 as the lifting seat 30 rises and falls, so that the moving body adjusts its position as the lifting seat 30 rises and falls. The positioning body is connected to the moving body and moves with the moving body to position the lithium battery end cap in the positioning groove 20a. Multiple positioning seats 40 move synchronously with the lifting seat 30, so that multiple positioning seats 40 can simultaneously position the lithium battery end cap in the positioning groove 20a in multiple directions, avoiding the situation where multiple positioning modules are independent and cannot be positioned synchronously, improving the positioning accuracy of the positioning device 100 and ensuring working efficiency.

If the specific posture changes, the directional indicator will also change accordingly.

[0052] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0053] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
