[0007] The core shaft is a cantilever beam structure.

[0008] The bottom plate is made of aluminum alloy.

[0009] A bearing is arranged between the core shaft and the bearing ring.

[0010] One end of the bearing is provided with a hole retaining ring, and the other end is provided with a shaft retaining ring.

[0011] The core shaft, end ring, bearing, bearing ring, shaft retaining ring and hole retaining ring are detachable structures.

[0012] The beneficial effects of the utility model are: automatic gluing is performed on products with a large number of production batches and little difference in shape, thereby improving the consistency of gluing and production efficiency; the structure is simple, disassembly is convenient, and replacement is quick.

[0017] The technical solution of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0018] Embodiment 1

[0019] As Figures 1 to 3 shown, an end - ring auxiliary glue - coating device includes a bottom plate 5 and a mandrel 1; a driving motor 3 is connected to the bottom plate 5, the output shaft of the driving motor 3 is connected to the mandrel 1, and the end ring 2 is sleeved on the mandrel 1; a bearing ring 7 is connected to the housing 10 of the driving motor 3 through a fixing plate 4, and positioning posts 11 are provided on the bearing ring 7.

[0020] The mandrel 1 is of a cantilever - beam structure.

[0021] The bottom plate 5 is made of aluminum alloy.

[0022] A bearing 6 is provided between the mandrel 1 and the bearing ring 7.

[0023] One end of the bearing 6 is provided with a hole retaining ring 9, and the other end is provided with a shaft retaining ring 8.

[0024] The mandrel 1, the end ring 2, the bearing 6, the bearing ring 7, the shaft retaining ring 8, and the hole retaining ring 9 are of detachable structures.

[0025] The working principle of the present utility model is: the driving motor 3 drives the mandrel 1 to rotate, the end rings 2 are neatly stacked on the mandrel 1 and rotate with the rotation of the mandrel 1, and then external glue brushes are used for glue - coating, and the glue - coating speed is adjusted through an external transformer.

[0026] Embodiment 2

[0027] The length, width, and height dimensions of the present utility model are: 200 mm × 100 mm × 100 mm. The mandrel 1 is of a cantilever - beam structure and is fixed by using a bearing 6 to ensure smooth rotation. Both ends of the bearing 6 are positioned by relying on the end - ring 2 at the shaft end, and the press - fitting method is used for installation during installation. The bottom plate 5 is made of aluminum alloy to ensure the equipment is stable and the weight is not too heavy. The function of the positioning post 11 is to limit the rotation of the end ring 2.

[0028] The mandrel 1, end ring 2, bearing ring 7, bearing 6, shaft retaining ring 8, and hole retaining ring 9 on the left part of the device are detachable and replaceable components. For end rings 2 of different sizes, the corresponding components are replaced as a whole. The main difference between components of different models lies in the different thicknesses of the mandrel 1. The diameter of the mandrel 1 is designed according to the diameter of the inner hole of the end ring 2, which can meet the requirements of gluing for end rings of different models. When replacing components, only the connecting screws between the fixing plate 4 and the bearing ring 7 need to be disassembled, which is convenient to disassemble and quick to replace.
