Description

Technical Field

[0001] The utility model relates to an arc coil iron core rubber coating tooling for watches, belonging to the technical field of iron core rubber coating. Background Art

[0002] The rubber coating material of the coil core usually has good insulation properties, which can ensure electrical isolation between coils and prevent short circuits and leakage. Before the existing arc coil core for watches is rubber coated, the core and coil need to be cleaned and dried to ensure that the tape can be tightly attached to the surface that needs to be rubber coated. During the rubber coating work, it is necessary to manually clamp the core with tweezers and wrap the insulating tape around the attached tape of the core. Since the coil core used for watches is small in size, the difficulty of rubber coating is increased. When the width of the tape is the same as the length of the part that needs to be rubber coated and is attached to the arc core, the center of the tape cannot fit tightly with the arc surface of the core, resulting in unqualified rubber coating. Therefore, it is very important to develop a rubber coating tool for arc coil cores for watches. Utility Model Content

[0003] The utility model aims at the deficiencies in the prior art and provides a rubber-coated tooling for arc-shaped coil iron cores used in watches.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A rubber-coated tool for arc-shaped coil iron core for watches comprises a main body, on which a plurality of positioning grooves for positioning the iron core are evenly arranged, the shape of the positioning grooves matches the shape of the iron core where the tape is attached, and an upper end rubber-coating area and a lower end rubber-coating area are arranged on the main body, both of which are used for attaching the tape.

[0006] Furthermore, a boss is provided on the main body, and the positioning grooves are evenly distributed on the boss.

[0007] Furthermore, the spacing between adjacent positioning grooves is three times the width of the positioning grooves.

[0008] Furthermore, the height of the positioning groove is the same as the height of the iron core where the tape is attached.

[0009] Furthermore, the connection between the adhesive tape in the upper adhesive area and the adhesive tape in the lower adhesive area is partially overlapped.

[0010] Furthermore, a notch groove is provided between adjacent positioning grooves.

[0011] Compared with the prior art, the beneficial effects of the utility model are: the structural parts of the present application are easy to operate, the iron core is effectively positioned through the positioning groove, and the arc-shaped structure of the iron core is coated with glue through the upper glue area and the lower glue area. The tape can be tightly and flatly attached to the surface of the iron core, which greatly reduces the difficulty of coating, ensures the quality of coating, and improves production efficiency.

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] like Figure 1-Figure 3 As shown, a rubber coating tool for arc coil iron core for watches includes a body 1, on which a plurality of positioning grooves 3 for positioning the iron core 4 are evenly arranged, and the shape of the positioning grooves 3 matches the shape of the iron core 4 where the tape is attached, and the body 1 is provided with an upper end glue area 5 and a lower end glue area 6, both of which are used for attaching tape. Multiple positioning grooves 3 can realize simultaneous positioning of multiple iron cores 4 for rubber coating, ensuring the stability of the iron core 4 during the rubber coating process, while ensuring the efficiency of the rubber coating, and adjusting the width of the rubber coating tape to ensure that the rubber coating is tightly connected to the iron core 4.

[0019] The body 1 is provided with a boss 2 , and the positioning grooves 3 are evenly distributed on the boss 2 .

[0020] The spacing between adjacent positioning grooves 3 is three times the width of the positioning groove 3 .

[0021] The height of the positioning groove 3 is the same as the height of the iron core 4 where the tape is attached.

[0022] The connection between the adhesive tape of the upper adhesive tape area 5 and the adhesive tape of the lower adhesive tape area 6 is partially overlapped.

[0023] like Figure 4As shown, a notch groove is provided between adjacent positioning grooves 3 .

[0024] When in use, the worker puts the iron core 4 into the positioning groove 3 one by one, and sticks the tape along one end of the body 1 to the other end, and the tape is stuck to the upper end glue area 5; use a cutting knife to cut the tape between adjacent positioning grooves 3, remove the iron core 4, wrap the tape around the iron core 4 one by one, and stick it tightly to it, and then put the iron core 4 with the glue wrapped again into the positioning groove 3, and stick the upper end glue area 5 in turn; stick the tape along one end of the body 1 to the other end again, and stick the tape to the lower end Glue area 6, use a cutting knife to cut the tape between adjacent positioning grooves 3, remove the iron core 4, wrap the tape around the iron core 4 one by one, and fit it tightly to complete the glue coating of the iron core 4. The structural parts of this application are easy to operate. The iron core 4 is effectively positioned through the positioning groove 3. The upper glue area 5 and the lower glue area 6 are used to realize the arc-shaped structure of the iron core 4. The tape can be tightly and flatly attached to the surface of the iron core 4, which greatly reduces the difficulty of glue coating, ensures the quality of glue coating, and improves production efficiency.
