[0016] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] A PCB board dispensing device includes a machine base 1, a base plate 3 and a base 2 supporting one end of the base plate 3 are arranged on the machine base 1, vertical rods 4 are arranged at the bottom of both ends of the base plate 3, and the two sets of vertical rods 4 are connected by a rack 5 passing through the base 2. A gear 6 that meshes with the rack 5 is arranged in the base 2. The gear 6 is driven by a motor 1. A limiting mechanism 7 is arranged on the machine base 1 below the suspended end of the base plate 3 to limit its movement. A lifting mechanism 8 is also evenly arranged on the top of the base plate 3.

[0018] Vertical plates 9 are provided on both sides of the base plate 3. A lead screw 10 driven by motor II is provided between the two sets of vertical plates 9. A slide block 11 is provided on the lead screw 10. A slide cylinder 12 is provided on the slide block 11. A dispensing assembly 13 is provided on the slide cylinder 12.

[0019] like Figure 2 As shown, the base 2 is provided with a sliding channel for the rack 5 to pass through, and the base 2 is also provided with a receiving cavity for accommodating the gear 6, one end of which is connected to the sliding channel.

[0020] like Figure 1 , 2 As shown, the vertical plate 9 is arranged on the same side as the base 2, the base 2 is located between the two sets of vertical plates 9, and the vertical plate 9 is provided with a bearing for fixing the end of the lead screw 10.

[0021] like Figure 1 , 2 As shown, the slide block 11 is provided with a screw hole for screwing the lead screw 10, and the slide block 11 is also provided with a sliding hole for the slide rod 14 to pass through. The two ends of the slide rod 14 are connected to the vertical plate 9.

[0022] The limiting mechanism 7 includes a longitudinal plate 71 disposed on the machine base 1 outside the base plate 3. The longitudinal plate 71 is connected to the base 2 via a crossbar 72. The bottom end of the base plate 3 is connected to a U-shaped plate 74 with its opening facing downward via a connecting rod 73. Two sets of roller groups 75 are arranged side by side in the opening of the U-shaped plate 74. The crossbar 72 passes through the opening between the upper and lower sets of roller groups 75. The two sets of roller groups 75 are respectively attached to the upper and lower corresponding end faces of the crossbar 72.

[0023] The lifting mechanism 8 includes grooves 81 evenly distributed on the top surface of the base plate 3. A top plate 82 is disposed in the grooves 81, and the top of the top plate 82 is flush with the top surface of the base plate 3. Rotating shafts 83 are disposed on the front and rear sides of one end of the top plate 82 and embedded in the side walls of the grooves 81. A mounting groove 84 is disposed at the bottom of the grooves 81 away from the rotating shafts 83. An elastic element 85, which is a spring, is disposed in the mounting groove 84 and connected to the top plate 82. A slot is also disposed at the bottom of the grooves 81 between the rotating shafts 83 and the mounting groove 84. An electromagnet 86 is disposed in the slot and magnetically connected to the bottom surface of the top plate 82.

[0024] Working principle: The PCB board is placed on the base plate 3. The motor II drives the lead screw 10 to rotate in the screw hole in the slide 11, thereby driving the slide 11 to move back and forth on the slide rod 14. At this time, the slide 11 drives the dispensing assembly 13 to move back and forth directly above the left end of the PCB board through the slide cylinder 12. During its back and forth movement, the slide cylinder 12 can drive the dispensing assembly 13 to move up and down, thereby performing dispensing work at different positions in the longitudinal direction of the top of the PCB board.

[0025] Simultaneously, the motor I can drive the gear 6 to rotate, and the rotating gear 6 drives the rack 5 to move left and right in the sliding channel, so that the rack 5 drives the base plate 3 and the PCB board above it to move left and right through the vertical rod 4. At this time, the dispensing assembly 13 can perform dispensing work on different positions in the horizontal direction of the top of the PCB board. This device can perform dispensing work on different areas of the top of the PCB board through the above two methods.

[0026] During the left and right displacement of the base plate 3, the roller assembly 75 will roll on the crossbar 72 via the connecting rod 73 and the C-shaped plate 74. This reduces the resistance caused by the limiting mechanism 7 when the base plate 3 moves, and also supports the right side of the base plate 3. When the left side of the base plate 3 is largely suspended on the left side of the base 2, the crossbar 72 can also pull the base plate 3 through the roller assembly 75, the C-shaped plate 74 and the connecting rod 73, thereby improving the stability of the base plate 3.

[0027] After processing, the PCB board is attached to the base plate 3, making it difficult for people to remove. At this time, the electromagnet 86 is de-energized. Without its magnetic attraction, the spring 85 extends and pushes the top plate 82 to rotate counterclockwise around the pivot 83. This causes the right end of the top plate 82 to slowly slide out of the groove 81. Finally, the angle between the top plate 82 and the base plate 3 is no more than 15 degrees. In this way, the product is lifted and suspended or tilted, making it easier for people to remove the PCB board. After the product is removed, the magnetic attraction generated by the electromagnet 86 acts on the top plate 82, causing it to rotate clockwise around the pivot 83 and compress the spring 85. Finally, the electromagnet 86 and the top plate 82 are magnetically connected, and the top plate 82 slides into the groove 81 to seal its top opening.

[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
