When the driving pin wheel 34 rotates, the auxiliary wheel 37 is rotated by the belt 39, and the electronic component strip 91 is moved synchronously by the driving pin wheel 34 and the auxiliary wheel 37, thereby, the auxiliary The wheel 37 can cooperate with the driving pin wheel 34 to stably drive the electronic component strip 91, and the auxiliary wheel 37 can provide the electronic component strip 91 to enter the strip track 21 before being aligned and aligned with the strip track 21 effects.

During the movement of the electronic component tape 91 in the tape groove 23, the movable cover plate 28 restricts the portion of the electronic component tape 91 located on the main base 221 from being warped upward, and Because the main limiting wall 222 and the auxiliary limiting wall 242 restrict the left and right sides of the electronic component strip 91 from being offset, the electronic component strip 91 can only move along the strip groove 23 Moreover, the electronic component strip 91 can be kept flat and stable during the moving process.

In the aforementioned first embodiment, the distance between the movable cover plate 28 and the main base 221 may also be greater than four times the thickness of the electronic component strip 91, although this arrangement will make the movable cover plate 28 The electronic component tape 91 no longer provides a limit function. However, under the condition that the rotation speed of the driving pin wheel 34 is stable, based on the driving pin wheel 34, the electronic component tape 91 is pulled outward from the tape track 21 In the relationship, the electronic component tape 91 located in the tape groove 23 does not have the problem of upward warping.
