Embodiment Construction

[0009] control figure 1 , the convex mold 5 is driven by the driving device to rotate synchronously with the heated resin material, and the convex part B on the peripheral part of the mold matches the shape of the pocket, because the heated resin material is close to the convex shape on the mold 5, so under the action of gravity, the heated resin material passing through the convex portion B on the mold makes a convex carrier tape C under vacuum conditions.

[0010] control figure 2 , the heated resin material is closely attached to the specific position A of the convex part B, and the inner side D of the pocket of the produced carrier tape C is produced by the convex part B on the convex mold 5. The shape of the pocket and the convex part The shape of B is consistent.

[0011] control image 3 , the material supply part 1, 2 fixes the resin material reel, rotates clockwise with the rotation of the final shaft 3', and enters the convex mold 5 through three heaters (the tem...

Abstract

A techonlogy for preparing the convex carrying belt of electronic elements includes such steps as feeding resin material from the reel driven by pressing axle, passing through 3 heater, coming in convex mould, thermal shaping, cooling by cooling plate, perforating on the shaped band, counting the holes, transverse cutting to divide it into 6 strips, taking central 4 strips as qualified ones, longitudinal cutting, and winding. Its advantages are no arc corner of shaped pocket for correctly inserting electronic elements in the pocket, high productivity and high quality.

Description

technical field [0001] The invention relates to a convex forming method of a carrier tape (braiding) that can be widely applied to electronic parts mounted on a circuit printed substrate, and belongs to the technical field of devices for carrying electronic parts. Background technique [0002] Accompanied by the widespread use of electronic components such as LEDs, capacitors, resistors, and ICs, industrial products such as mobile phones and computers are gradually developing in the direction of light, small, low-cost, and high-performance. All electronic components mounted on circuit printed substrates are inseparable from the carrier tape (braid). The "pocket" of the carrier tape (tape) carrying the electronic components must also be adapted to the shape and size of the components. The specifications of small electronic components are generally 1005 (length 1.0mm, width 0.5mm and depth 0.5mm), and the carrying tape (braid) for placing electronic components of this specifi...
