[0027] When the present technical solution is implemented, the material comes out of the vibration plate 10 and moves forward along the conveying guide groove; the driving component 3 drives the material receiving platform 37 to move, so that one of the receiving holes is connected with the conveying guide groove, and the material transitions from the conveying guide groove to the receiving hole; then the driving component 3 drives the material receiving platform 37 to move, so that the other receiving hole is connected with the conveying guide groove, and the next material enters the other receiving hole from the conveying guide groove; then the driving component 3 drives the material receiving platform 37 to move to a predetermined position, and the materials in the two receiving holes correspond to the picking components 5; finally, under the drive of the XYZ moving mechanism, the two picking components 5 first pick up the materials, and then transfer them to the top of the processed PCB board, and insert the materials into the PCB board; the materials can be electronic components, such as: sensors, capacitors, inductors, etc.

[0028] Furthermore, a bracket 35 is provided above the material receiving platform 37 , and the bracket 35 is connected to a sensor 36 for sensing the material entering the receiving hole.

[0029] The sensor 36 may be a light sensor 36 , a proximity switch, etc. By providing the sensor 36 , the action of the driving component 3 is controlled.

[0030] See also Figure 3 The driving assembly 3 includes a lower slide cylinder 32 and an upper slide cylinder 34 , the lower slide cylinder 32 is connected to the upper slide cylinder 34 through an intermediate seat 33 ; the upper end of the upper slide cylinder 34 is fixedly connected to a material receiving platform 37 .

Since the strokes of the upper slide cylinder 34 and the lower slide cylinder 32 are relatively short, in order to make the distance between the two receiving holes larger, two slide cylinders are set; during operation, the lower slide cylinder 32 drives the middle seat 33 to move, and the middle seat 33 drives the upper slide cylinder 34 and the material receiving platform 37 to move, so that one of the receiving holes corresponds to and is connected with the conveying guide groove, and after the material enters the receiving hole, the lower slide cylinder 32 drives the middle seat 33 to reset; then the upper slide cylinder 34 drives the material receiving platform 37 to move, so that the other receiving hole on the material receiving platform 37 corresponds to and is connected with the conveying guide groove, and after the material enters the receiving hole, the upper slide cylinder 34 drives the material receiving platform 37 to reset.

[0032] See also Figure 1 , Figure 2 , Figure 4The XYZ moving mechanism includes a lateral moving mechanism 1 and a longitudinal moving mechanism 2 which are connected to each other.

Therefore, during installation, the spacing of the lifting mechanism 7 fixing the two picking components 5 needs to be adjustable. The technical solution sets a position adjustment component to make the position of the bearing plate adjustable, thereby achieving the purpose of adjusting the position of the lifting mechanism 7. It is convenient for installation and operation.

[0036] When adjusting, longitudinal adjustment is mainly performed; this technical solution adopts the adjustment method of bolt 6, through the threaded connection between bolt 6 and bearing block 4, rotating bolt 6 drives bearing block 4 to move; secondly, in order to facilitate the fixing of bolt 6, a limit ring 61 is sleeved on the light rod part of bolt 6, and limit ring 61 cooperates with the head of bolt 6 to form a clamping connection with L-shaped fixing block 8, and bolt 6 can only rotate relative to L-shaped fixing block, and cannot move longitudinally. Secondly, in order to prevent the rotation of bolt 6 due to vibration during operation, causing bearing block 4 to move; therefore, a waist-shaped hole is set on bearing block 4, and once the adjustment is completed, bearing block 4 is fixed to longitudinal moving plate 25 by bolts or screws.
