The above-mentioned IC tape pressing device and IC tape pressing rail combination are pressed by a plurality of passive wheels arranged in a row on the IC tape, thereby providing stable pressing of the IC tape while the IC tape is moving And smooth effect.

In order to explain the technical features of the present invention in detail, the following preferred embodiments are described below with reference to the drawings, in which:

As shown in FIGS. 1 to 4, the IC tape pressing device 10 provided by the first preferred embodiment of the present invention is mainly composed of a frame plate 11 and a plurality of elastic pressing wheel sets 21, in which:

The shelf plate 11 is used to be fixed on a rail 41 of a machine (not shown). The shelf plate 11 has a plurality of perforations 12 arranged in two rows, each paired in two rows The methods are pairwise. The rack plate 11 is provided with a plurality of fixing holes 14 through which bolts 19 can pass to be fixed on the rail 41.

In the plural elastic pressing wheel sets 21, each of the elastic pressing wheel sets 21 has a shaft 22, which is movably penetrated through one of the perforations 12 of the frame plate 11 through a bearing 23, and the shaft 22 has a The blocking portion 221 is located above the shelf plate 11, a fixing block 24 is fixed at the bottom section of the shaft 22, and a spring 26 is sleeved on the shaft 22, and two ends of the spring 26 are respectively pressed against the shelf plate 11 and The elastic restoring force of the fixing block 24 keeps the fixing block 24 and the shaft 22 moving downwards, and the stopper 221 abuts against the frame plate 11. The fixing block 24 is also fixed to the bottom section of the shaft 22 of the other elastic pressing wheel set 21 paired with each other, so that the two paired shafts 22 move together. The springs 26 of the plurality of elastic pressing wheel sets 21 have the same elastic coefficient.

A wheel shaft 241 is provided on one side of each fixed block 24. The wheel shaft 241 is provided with a driven wheel 25, and the bottom edge of the driven wheel 25 is lower than the bottom edge of the fixed block 24. The passive wheels 25 of the plurality of fixed blocks 24 are the same The sides are arranged in a row, and the plurality of passive wheels 25 are used to press on an IC material belt 91. When the IC material belt 91 moves, the plurality of passive wheels 25 are driven to rotate in the same direction.

The above is the structure of the IC tape pressing device 10 of the first embodiment of the present invention, and as shown in FIGS. 5 to 8, the IC tape pressing track assembly 40 of the present invention, in addition to the above-mentioned IC tape In addition to the pressing device 10 (refer to FIGS. 1 to 4), it also includes:

A rail 41 having a fixing plate 42 and a bottom plate 44 located below the fixing plate 42. The bottom plate 44 has a rail groove 45. The bottom surface of the rail groove 45 is used as a contact surface 451. The shelf plate 11 is locked to the fixing plate 42 by the bolts 19 through the plurality of fixing holes 14. Wherein, the track groove 45 is used for the IC material tape 91 to enter and pass through. In practice, the width of the track groove 45 is slightly wider than the IC material tape 91, by which the IC material tape 91 can be accommodated, and The direction of the IC tape 91 can be restricted so that it can only move along its long axis direction.

In actual use, if the IC 92 on the IC tape 91 needs to be turned down to move the IC tape 91, the track groove 45 needs to be provided with a groove 452 at the bottom along the long axis direction. And the contact surface 451 is located beside the groove 452. In this way, when the IC tape 91 is placed in the track groove 45, the IC 92 of the IC tape 91 facing down can be accommodated in the groove 452. However, if the IC 92 on the IC tape 91 does not need to face down, the groove 452 is unnecessary.

The plurality of passive wheels 25 are pressed against the abutment surface 451, whereby when the IC tape 91 is located in the track groove 45, a portion of the IC wheel 91 extends into the plurality of passive wheels 25 and the abutment surface Between 451, by this, it is pressed and pressed against the abutment surface 451.

The structure of the IC tape pressing device 10 and the IC tape pressing rail assembly 40 has been described above, and the operation mode will be described next.

Before the operation, an IC material tape 91 is entered into the track groove 45, and the IC material tape 91 is directed downwards to accommodate the IC 92 in the groove 452, and the plurality of passive wheels 25 to charge the IC material The belt 91 is pressed on the abutment surface 451. Since the plurality of driven wheels 25 are arranged in rows, a long pressing area can be formed. In this pressing area, even if the IC material belt 91 is moving, it can still ensure The flatness and stability of the IC tape 91 facilitates the subsequent inspection, scanning, and processing of the IC 92 on the IC tape 91.

During operation, a feed device (not shown) is used to drive the IC material belt 91 to move. At this time, the passive wheel 25 on the plurality of elastic pressing wheel sets 21 is driven to rotate, by which The elastic coefficients of the springs 26 are the same, which can ensure that the force of each passive wheel 25 pressing on the IC tape 91 is the same, thereby making the IC tape 91 remain flat and stable in the pressed portion. In addition, since each of the fixing blocks 24 is fixed on the two shafts 22 in pairs, the elastic pressing wheel set 21 in pairs is synchronized, and the two shafts can be used The arrangement relationship of the rod 22 on the frame plate 11 keeps its moving path from shifting, even if the passive wheels 25 on the side of each fixing block 24 are pressed and the reaction force is not at the axis of the two shafts 22 It will not cause the two shafts 22 to shift in the direction of movement.

Please refer to FIG. 9 again, an IC tape pressing device 10' provided by the second preferred embodiment of the present invention is mainly the same as the first embodiment disclosed above, except for:

The plurality of perforations 12' on the shelf plate 11' are arranged in a row instead of two rows.

Thereby, the plurality of elastic pressing wheel sets 21 ′ provided on the plurality of through holes 12 ′ will be arranged in a row with the arrangement of the plurality of through holes 12 ′, and the fixing blocks of each elastic pressing wheel set 21 ′ 24 ′ is arranged on its shaft 22 ′ separately, and will not be arranged on the shaft 22 ′ of other elastic pressing wheel sets, and can still be used to set the wheel 241 ′ and the driven wheel 25 ′.

The second embodiment is mainly for explaining that the plurality of perforations 12' of the IC tape pressing device 10' does not necessarily need to be arranged in two rows, but one or more rows may be used. In addition, referring to the above first embodiment, it can be known that the IC tape pressing device 10 ′ can also be arranged on a track (not shown in the figure) to form an IC tape pressing track combination, and the cooperative arrangement method has been described in the foregoing embodiment , I will not repeat them here.

The remaining structures of the second embodiment and the achievable effects are the same as those in the first embodiment disclosed above, and will not be repeated here.

It can be seen from the above that the combination of the IC material tape pressing device 10 and the rail provided by the present invention can provide the IC material tape 91 with a stable pressing and smoothing effect while the IC material tape 91 moves.
