Detailed Description

The following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1-2.

Example 1: a carrier tape, comprising: the device comprises a body 1, wherein at least one of two sides of the body 1 is provided with a plurality of traction holes 2; the middle part of the body 1 is provided with a plurality of cavities 4 formed by bending downwards, the cavities 4 are arranged at equal intervals, a connecting sheet 3 is formed between the adjacent cavities 4, and at least one force unloading groove 5 is arranged on the connecting sheet 3 in the direction vertical to the length of the body 1.

When the applicant researches the stress condition of carrier tape rolling, the applicant finds that when the carrier tape is spirally rolled, pulling force is mutually exerted between two adjacent cavities 4 through connecting pieces 3; because the cavities 4 have the same structure and the same elastic modulus of deformation, the pulling force has the same direction to each action, and when the pulling force is larger, the adjacent cavities 4 basically deform under the action of the pulling force; the pulling force is related to the inner diameter of the package, generally, the smaller the inner diameter, the greater the pulling force; in order to avoid larger pulling force, the minimum inner diameter ratio of the package of the carrier tape is larger, and when the minimum inner diameter is set to be larger, the winding length of the carrier tape is directly reduced under the limitation of the maximum outer diameter; the winding cost is increased. After many studies, the applicant sets the force-releasing slot 5 between the adjacent cavities 4, so that the pulling force between the cavities 4 is converted into: unload the power of dragging between power groove 5 and the die cavity 4, the structure of die cavity 4 is different with the structure of unloading power groove 5, under the effect of the power of dragging, unload power groove 5 and take place earlier and warp, and then reduce the size of dragging the power to avoid die cavity 4 to need bear great power of dragging, also avoid die cavity 4 to take place to warp. Therefore, after the force-releasing groove 5 is added, the lower limit of the minimum inner diameter of the carrier tape can be increased when the carrier tape is rolled, and the minimum inner diameter of the rolled carrier tape is as follows: 40mm, and the minimum inner diameter of the coiled pipe can be 30mm after the force unloading groove 5 is arranged.

Further, the width of the force-discharging slot 5 is larger than half of the width of the connecting piece 3.

The force-releasing slot 5 needs to block the connection between the adjacent cavities 4, and if the width is small, a large pulling force still exists between the two adjacent cavities 4, so that the blocking effect is difficult to achieve.

Further, the depth of the force-discharging groove 5 is D, and the depth of the cavity 4 is D, 4D > D > 2D.

After the adjacent cavities 4 are blocked, the force unloading groove 5 needs to deform during rolling so as to reduce the pulling force; it is considered that the depth of the force-discharging groove 5 needs to be maintained within a certain ratio with respect to the depth of the cavity 4 through experiments.

Further, the connecting piece 3 is provided with 2 or more than 2 force discharging grooves 5, and the sum of the lengths of all the force discharging grooves 5 on each connecting piece 3 is not less than two thirds of the length of the connecting piece 3.

When the connecting piece 3 is provided with a plurality of force-discharging grooves 5, the force-discharging grooves 5 need to be blocked, and the length of the force-discharging grooves needs to occupy a certain proportion.

Further, the force-discharging slot 5 is waist-shaped.

In order to facilitate the manufacture of the force-discharging groove 5, the force-discharging groove is arranged to be waist-shaped, namely long round shape.

Furthermore, both sides of the body 1 are provided with a plurality of traction holes 2.

For convenient traction, both sides of the body 1 are provided with traction holes 2.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the present description should not be interpreted as a limitation to the present invention.
