The structure of the first embodiment has been described above, and the operation state of the first embodiment will be described next.

As shown in Figures 7 to 9, before use, the movable cover 28 should be opened to the opened position, that is, it will not be located above the main bearing platform 221 and the auxiliary bearing platform 241. The tape trough 23 is in an open state. Then put an electronic component tape 91 into the tape slot 23, and make the electronic component 92 on the electronic component tape 91 face down so that the electronic component 92 can be located in the gap when passing through the tape slot 23 25. At this time, the electronic component tape 91 is partially placed on the surface of the main bearing platform 221 and the auxiliary bearing platform 241, and both sides of the electronic component tape 91 are subjected to the main limiting wall 222. And the limitation of the auxiliary limiting wall 242. Then move the movable cover 28 to the cover position, as shown in Figs. 8 and 9. Since the distance between the movable cover 28 and the main platform 221 is greater than the thickness of the electronic component strip 91, the electronic component strip 91 can be allowed to move, but the electronic component strip 91 can be restricted from moving upwards. Warped. In addition, the electronic component tape 91 is also moved to be positioned on the driving pin wheel 34 and the auxiliary wheel 37, so that the plurality of guide pins 341, 371 on the driving pin wheel 34 and the auxiliary wheel 37 can pass through the electronic component material.

The direction of rotation of the driving pin wheel 34 is to make the electronic component tape 91 leave the tape. Rotating in the direction of the track 21, that is, the electronic component tape 91 is driven by pulling out from the tape track 21. When the driving pin wheel 34 rotates, the guide pin 341 will gradually penetrate/leave. The positioning hole 911 on the electronic component tape 91 may cause the electronic component tape 91 to jump due to the angle of insertion or withdrawal at the moment of penetration or exit. However, the main anti-dropping member The outer edge of 35 is pressed against the electronic component strip 91, and at the same time the plural guide pins 341 penetrate the positioning hole 911 of the electronic component strip 91 and enter the through slot 351, thereby ensuring the electronic component strip 91 is stably suppressed and engages with the plurality of guide pins 341 without jumping, thereby avoiding the failure of the guide pin 341 to be inserted into the positioning hole 911 on the electronic component strip 91 to cause tooth skipping or loss of step. Happening. When the driving pin wheel 34 rotates, the auxiliary wheel 37 is driven to rotate by the belt 39, and the electronic component tape 91 is synchronously driven by the driving pin wheel 34 and the auxiliary wheel 37 to move. The wheel 37 can cooperate with the driving pin wheel 34 to stably drive the electronic component tape 91, and the auxiliary wheel 37 can provide the electronic component tape 91 to enter the tape track 21 and align with the tape track. 21 effects.

During the movement of the electronic component tape 91 in the tape groove 23, the movable cover 28 restricts the portion of the electronic component tape 91 on the main platform 221 so that it cannot be warped upward, and Since the main limit wall 222 and the auxiliary limit wall 242 limit the left and right sides of the electronic component tape 91 so that it cannot be shifted, the electronic component tape 91 can only move along the tape slot 23 , And can keep the electronic component strip 91 flat and stable during the moving process.

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

As shown in Figure 11, when the second embodiment is in operation, one side of the electronic component tape 91 is accommodated in the auxiliary limiting groove 444, thereby forming upper and lower limits on the electronic component tape 91 The position effect makes the electronic component strip 91 less likely to warp upward due to external force. Since the auxiliary driving device 58 and the driving device 52 move simultaneously, the driving pin wheel 54 and the auxiliary wheel 57 also rotate synchronously, thus ensuring that the electronic component tape 91 can move smoothly in the tape slot 43 . The auxiliary anti-dropping component 59 has the same function as the main anti-dropping component 55, and is used to provide a stable anti-dropping effect when the electronic component strip 91 is engaged with the guide pin 571 on the auxiliary wheel 57 to prevent jumping.
