Improved structure of carrier-stable mechanism

This creation is related to the carrier tape forming technology, and in particular to an improved construction of a carrier-stable mechanism.

Press, the application of carrier tape on the packaging of electronic components is an indispensable part of the automated process. After the electronic components are properly packaged by the preset chamber on the carrier tape, The packaged electronic components provide protection. In addition, the electronic components are regularly supplied to meet the manufacturing process of the automated manufacturing process. Specifically, the preset chambers on the carrier tape are usually made of molds. Under the thermal energy supply, the sheet carrier tape is subjected to a hot press forming process to form a chamber space of a desired depth, shape and quantity on the sheet carrier tape for accommodating electronic components therein.

Among them, in order to avoid the deformation of the sheet-like carrier tape during the hot pressing process of the mold, the edge of the sheet body is deformed by heat, and the prior art is similar to the technology disclosed in the new patent No. M381592 of the prior art. Appropriate guide grooves are respectively arranged on both sides of the carrier tape to reduce the temperature of the guide grooves, so that the environment on both sides of the carrier tape is a relatively low temperature space, thereby avoiding forming in hot pressing. During the process, the deformation of the belt edges on both sides of the carrier tape is caused.

It is a well-known technique. For a stable effect of a small-width carrier tape, it can be achieved to a desired degree. However, due to the wide variety of electronic components, the external dimensions and even the applicable application are added. The working methods are all different. At this time, the conventional stabilization technique for stabilizing the shape of the edge of the carrier tape achieves a stable effect on the carrier tape having a large width, that is, it is not ideal, and the wide carrier tape is made. After hot press forming, there is still a general lack of deformation such as shrinkage and bending.

Therefore, the main purpose of this creation is to provide an improved structure for the carrier-stable mechanism, which can improve the stability of the carrier-stable mechanism for the carrier tape, especially for the carrier tape with a larger width. The best stable effect.

The reason is that, in order to achieve the above objectives, the main structural feature of the improved structure of the carrier with a stable mechanism is that when the carrier tape is subjected to a hot press molding process, the carrier is The carrier tape may be a portion other than the hot pressing range, and the clamping portion is clamped so that the carrier tape is sandwiched, in addition to being isolated from the mold, and the sandwiched portion can be further placed at In a relatively low temperature environment, to ensure that its shape is not affected by external thermal energy.

Specifically, the improved structure of the carrier tape stabilization mechanism includes a base portion having two first end faces spaced apart from each other, and a clamping portion having two second end faces respectively facing the first end faces And each of the first end faces are spaced apart from each other by a clamping distance; a first driving portion drives each of the second end faces to be linearly reciprocatingly displaced from and away from the first end faces, respectively, according to which The clamping pitch.

Thereby, the elongated carrier tape is moved along its long axis direction, and the edge of both sides of the long axis is slidably connected to each of the first end faces, thereby being properly guided to maintain a stable traveling direction. At the same time, when the carrier tape forming machine supplies thermal energy to the carrier tape and continues to mold the shape of the discharge chamber by the mold, the first driving portion synchronously drives the second end faces toward the first end face. Closely, the edge of the two sides of the long axis of the carrier tape is sandwiched between each of the first end faces and each of the second end faces, and the shape of the edges of the two sides of the long axis of the carrier tape is maintained to maintain a flat state.

Further, in order to ensure the flatness of the edge shape of the two sides of the long axis of the carrier tape, the improved structure of the carrier tape stabilization mechanism further includes a heat dissipating portion, which is disposed in the base portion for presenting on the base portion The heat is dissipated outwards to ensure that the environment in which the edges of the carrier are located is in a relatively low temperature environment.

In addition, in order to properly guide and support the edges of the two sides of the long axis of the carrier tape, the base portion further comprises two straight strip-shaped guide rails which are parallel and spaced apart from each other, and the two notch grooves are The guide rails are disposed on opposite sides of the guide rails and extend along the long axis of each of the guide rails.

Each of the first end faces is located on a side groove wall of each of the notch grooves.

Wherein, each of the first end faces is located on the same horizontal plane.

Wherein, the clip portion further comprises two strip-shaped lid bodies which are parallel to each other and spaced apart from one side of the base portion.

Wherein, the clip portion further comprises a two-end body extending outward from one side end of each of the cover bodies, and each of the second end faces is formed by an end surface of the extended end end.

Wherein, each of the second end faces is located on the same horizontal plane.

The first driving unit includes at least two first fluid pressure cylinders respectively fixed to the base, and respectively connected to the cover bodies at the output shaft ends.

In addition, in addition to the flatness obtained by the above-mentioned technique, in order to improve the strength of the carrier tape after molding, when the carrier tape is applied by the aforementioned clamping force, a further external force can be applied to carry the carrier tape to the belt. The two sides of the body expand, and the external force causes the molecular arrangement of the carrier tape made of the polymer material to be aligned, thereby eliminating the inherent stress, thereby ensuring the flatness of the carrier tape after molding. In addition to the degree of uniformity, it can increase its mechanical strength to avoid distortion, warpage and improve its weather resistance.

In order to improve the mechanical strength after the carrier tape is formed, the improved structure of the carrier tape stabilization mechanism further includes a second driving portion that drives the first end faces to be linearly reciprocating relative to each other, thereby changing Each of the first end faces is spaced apart from each other.

Wherein, the base has two pier members, a first rail is bridged and fixed between the pier members, and a second rail is slidably disposed between the pier members parallel to the first rail, and Each of the first end faces is disposed on each of the guide rails; the second drive portion drives the second guide rails to reciprocally displace on the pier members by the output shaft end, and the distance between the first end faces is changed.

The second driving part further includes two connecting members fixed to the second guide rail and respectively slidably connected to the respective pier members, and two second fluid pressure cylinder members are respectively disposed on each of the pier members. And the output shaft ends are respectively connected to the respective connecting members.
