Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The small sign assembly and core parts in the gear block are always prone to large gap problems after assembly, but the actual required gap is close to zero. The tape is pasted after the product is lowered in advance to compensate for the tape itself. Instability brought about to achieve product consistency.

In the present embodiment, the method for improving the gap between the tape-attached parts during the gear installation process includes the following steps:

S1: Lower the matching surface 11 of the label positioning plate 1 with the adhesive tape.

In general, the present technical solution compensates for the gap caused by uneven sticking of the tape through the drop of the matching surface 11 of the tape. During specific implementation, the process of lowering the surface is, based on the design size of the mold, adjust the mold size on the original mold design, so that the injection molded sign positioning plate 1 reduces the thickness D on the tape matching surface 11, and the thickness D is the gap. The margin corresponds to 85% to 95% of the thickness, that is, a part of the elastic margin is left. The way to reduce the cavity of the mold is to increase the thickness of the mold on one side of the matching surface 11 of the tape. The clearance allowance is the average value of the measured clearance values between the core piece 4 and the small plate assembly. The thickness corresponding to the gap allowance is the height of the sign board relative to the original position. The way to adjust the mold is to reduce the cavity of the mold.

S2: Paste the adhesive tape 2 on the sign positioning plate 1 after the lower surface;

S3: install the sign indicating plate 3 on the sign positioning plate 1 to form a small sign assembly;

S4: Assembling the small signage assembly and the core piece 4 .

It can be seen that through this technical solution, it is possible to lower the matching surface of the product and the tape at the initial stage of product development to compensate for the gap caused by the uneven pasting of the tape, thereby improving the gap of the entire product and solving the problem of core parts. After assembly, the gap is too large.

Based on the feasible combination of different types of adhesive tape 2, sign positioning plate 1, sign indicating plate 3, and core piece 4 in the gear installation process, record the appropriate thickness D one by one to form a data set. In S1, use the data set based on the corresponding Thickness D sets the mold size parameters during the lowering process.

During specific implementation, the codes corresponding to different types of adhesive tape 2, sign positioning plate 1, sign indicating plate 3, and core member 4 are respectively x, y, z, and m, so as to form the mapping of the above four to the thickness D, that is D=f(x, y, z, m), through a reasonable selection of a reasonable set of x, y, z, m, the corresponding thickness D can be generated, so as to set the mold size parameters in the process of lowering the surface.
