[0030] As shown in Figures 1-6, a first aspect of this application provides a blank PCB board feeding device, including:

[0031] The feeding box 1 has multiple hoppers 11, each hopper 11 having a push port 111 and a discharge port.

[0032] Material support assembly 2, which can enter the hopper 11 through the pusher port 111 and drive the material in the hopper 11 upward to the discharge port.

[0033] The material storage detection unit 3 is connected to the material support assembly 2. The material storage detection unit 3 can move with the material support assembly 2 to each hopper 11 of the feeding box 1 to detect whether there is material stored in the corresponding hopper 11.

[0034] And a positioning detection unit 4, which corresponds to the hopper 11, is used to detect whether the material has moved to the discharge port.

[0035] The material support assembly 2 includes a support plate 21, a lifting component 22, and a translation component 23. The support plate 21 is connected to the lifting component 22, and the lifting component 22 is connected to the translation component 23. The material storage detection unit 3 is located below the support plate 21. The material storage detection unit 3 includes a material storage detection photoelectric sensor, which is located below the support plate 21. The support plate 21 has a sensing through-hole 211 for light beams to pass through. The material storage detection photoelectric sensor is a reflective photoelectric sensor. After the light beam passes through the sensing through-hole 211, it enters the hopper 11 through the push port 111. When there is material stored in the hopper 11, the photoelectric sensor receives the light reflected back from the material.

[0036] The material hopper 11 has a positioning detection hole 112 at its discharge port. The positioning detection unit 4 includes a detection mounting bracket 41 and a positioning detection photoelectric sensor 42. The detection mounting bracket 41 has an elongated mounting groove, and the positioning detection photoelectric sensor 42 is installed in the mounting groove and corresponds to the positioning detection hole 112. The positioning detection photoelectric sensor 42 can be a reflective photoelectric sensor or a through-beam photoelectric sensor, preferably a through-beam photoelectric sensor. A detection mounting bracket 41 is installed on each side of the material feeding box 1, with a transmitter installed on one side and a receiver installed on the other side, which can more accurately detect whether the material has reached its position.

[0037] Furthermore, the blank PCB board feeding device also includes a feeding rack 5 for placing the feeding box 1. The detection mounting bracket 41 is installed on the feeding rack 5. The feeding rack 5 is provided with a positioning groove. The feeding box 1 is manually placed into the positioning groove of the feeding rack 5. The feeding box 1 is provided with handles on both sides to facilitate manual handling of the feeding box 1.

[0038] The lifting component 22 includes a lifting mounting plate 221, a lifting motor 222, a lifting screw 223, and a lifting frame 224. The support plate 21 is fixed on the lifting frame 224. The lifting frame 224 is connected to the lifting screw 223, and the lifting screw 223 is connected to the lifting motor 222. The lifting mounting plate 221 is connected to the translation component 23. The lifting motor 222 drives the lifting screw 223 to rotate, thereby causing the lifting frame 224 and the support plate 21 to move up and down.

[0039] The translation component 23 includes a translation cylinder 231, a translation slide rail 232, and a translation slider 233. The translation cylinder 231 is connected to the translation slider 233, and the translation slider 233 is connected to the translation slide rail 232. The lifting component 22 is connected to the translation slider 233. The translation component 23 is used to drive the lifting component 22 and the support plate 21 to move along the X-axis.

[0040] It should be noted that the translation component 23 is used to move the pallet 21 to below each hopper 11. In this embodiment, the feeding box 1 has two hoppers 11 arranged along the X-axis. The translation component 23 is used to move the lifting component 22 and the pallet 21 between the two hoppers 11 along the X-axis. It is understood that the hoppers 11 of the feeding box 1 are not limited to the two mentioned above, and their arrangement is not limited to the arrangement along the X-axis. The translation component 23 can be modified according to the different arrangements of the hoppers 11 in the feeding box 1. For example, when the feeding box 1 has hoppers 11 arranged along the Y-axis, a translation component 23 with X-axis and Y-axis movement functions can be used.

[0041] Multiple blank PCB boards are stacked in the hopper 11, with spacers between them. The blank PCB board feeding device also includes a visual inspection camera 6 for distinguishing between the blank PCB boards and the spacers, and the visual inspection camera 6 is located above the feeding hopper 1.

[0042] The blank PCB board feeding device also includes a material handling robot 7, which is used to move the blank PCB board to the processing station or move the separator paper to the separator paper receiving station. Blank PCB boards and separator paper are stacked sequentially in the hopper 11. A vision inspection camera 6 distinguishes the materials to be extracted, thereby controlling the material handling robot 7 to move the blank PCB board to the processing station or the separator paper to the separator paper receiving station. Specifically, the material handling robot 7 can move the material to the processing station or the separator paper receiving station using vacuum suction.

[0043] The visual inspection camera 6 is also used to detect the placement orientation of the blank PCB board. If the placement orientation is incorrect, the orientation of the blank PCB board can be corrected by rotating the material handling robot 7.

[0044] A second aspect of this application also provides a feeding method, including:

[0045] The material support assembly 2 moves to the bottom of the hopper 11 of the feeding box 1, and the material storage detection unit 3 detects whether there is material stored in the hopper 11;

[0046] If there is no material in the hopper 11, the material support component 2 moves to the next hopper 11 and checks whether there is material stored in the hopper 11. When it is detected that there is no material in all hoppers 11, an alert is issued.

[0047] After detecting that there is material in the hopper 11, the material support component 2 enters the hopper 11 through the push port 111 of the hopper 11, driving the material to move upward, and the position detection unit 4 detects whether the material has moved to the outlet of the hopper 11.

[0048] After the material moves to the discharge port, the vision inspection camera 6 distinguishes whether the material at the discharge port is a blank PCB board or a paper separator. If it is a blank PCB board, the material handling robot 7 moves it to the processing station; if it is a paper separator, the material handling robot 7 moves it to the paper separator receiving station. Specifically, the material handling robot 7 can move the material to the processing station or the paper separator receiving station by vacuum adsorption.

[0049] Furthermore, when the visual inspection camera 6 detects that the material at the discharge port is a blank PCB board, it checks whether the placement direction of the blank PCB board is a preset direction. If it is not a preset direction, the material handling robot 7 is rotated to adjust it to the preset direction when the blank PCB board is taken out.

[0050] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
