Based on the fact that the contact area of two adjacent second material parts 21 in the horizontal direction is small, the seventeenth driving assembly 3244 is used for driving the second material parts 21 to move along the horizontal direction, and then the sixteenth driving assembly 3242 is used for driving the second material parts 21 to move along the vertical direction, so that the situation that the second material parts 21 are separated together due to the fact that the adjacent second material parts 21 are overlapped due to the third protrusions 214 is avoided.

That is, two first protrusions 213 are provided in the diagonal direction of the second material 21, so that two limiting grooves, i.e., a second limiting groove 3246 and a third limiting groove 3247 shown in fig. 24, are provided at the top end of the third base 3241. When the second material member 21 is transferred onto the third base 3241, the first protrusion 213 of the second material member 21 matches with the limiting groove. The limiting groove can be used for limiting the position of the second material part 21 on one hand, and can improve the stability of the second material part 21 in the moving process on the other hand. The stopper groove of the third base 3241 is set according to the structure of the second material 21 itself, and this embodiment is not limited thereto.

In an embodiment, as shown in fig. 19, a first groove 3221 is disposed on the second base 322, the first groove 3221 corresponds to a position of the moved second material 21, and a position-limiting step 3222 matched with the shape of the second material 21 is disposed on the first groove 3221.

That is to say, when the second material part 21 moves to the third step, the limiting step 3222 matches with the third protrusion 214 on one side of the second material part 21, and when the position of the second material part 21 is wrong, for example, rotates by 180 °, the limiting step 3222 will limit the upward movement of the second material part 21, so as to improve the material distribution quality of the second material part 21. Of course, the position-limiting step 3222 is set according to the specific shape of the second material member 21, and the application is not limited thereto.

Based on the volume of second material 21 is less, for improving packaging efficiency, encapsulate a plurality of second material 21 on a PCB board, cut apart again after the equipment is accomplished. In the embodiment of the present invention, three second components 21 or a multiple of three second components 21 are mounted on the PCB, that is, the picking assembly will pick up three second components 21 at a time and package the three second components 21 on one PCB. In the above embodiment, the limiting groove is provided on the third base 3241 to improve the stability of the second material 21 during the movement, but since the volume of the second material 21 is smaller, the first protrusion 213 on the second material 21 is smaller, and therefore the limiting groove has a limited effect of limiting the stability of the second material 21 during the movement.
