[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 and Figure 3, an embodiment provided by the present utility model: a PCB board feeding device, including a base 1. The left part of the base 1 can be connected to a lead screw device, so that it can move up and down for feeding and loading the PCB board. A positioning rod 5 is fixedly connected to the upper part of the base 1. The positioning rod 5 can support and fixedly connect the connecting block 10 at different positions. A card slot 6 is opened inside the positioning rod 5. The positioning rod 5 restricts the connecting block 10 to only slide vertically, and the card slot 6 can be clamped with a card block 11 so that the position of the connecting block 10 relative to the positioning rod 5 is fixed. A card block 11 is slidably connected inside the card slot 6. The lower part of the card block 11 is a slope and can slide into the inside of the connecting block 10 under extrusion to facilitate the clamping of the connecting block 10. Two groups of card blocks 11 are provided. The two groups of card blocks 11 are elastically connected by a first spring 14. The extrusion of the first spring 14 can make the card block 11 slide into the inside of the card slot 6, making the operation of clamping the connecting block 10 more convenient. The two ends of the first spring 14 are respectively fixedly connected to the outer sides of the two groups of card blocks 11. The extrusion of the first spring 14 can make the card block 11 remain fixed inside the connecting block 10. A slope block 12 is slidably connected inside the front end of the card block 11. The rear end of the slope block 12 is a slope, which can extrude the card block 11 to slide into the inside of the connecting block 10 to release the limit, facilitating disassembly. The outside of the slope block 12 is slidably connected to the outside of the front end of the connecting block 10. The connecting block 10 restricts the slope block 12 to only slide horizontally in a straight line within a fixed distance. A button 13 is fixedly connected to the side end of the slope block 12. The button 13 can conveniently drive the slope block 12 to slide. The outside of the button 13 is slidably connected to the outside of the front end of the connecting block 10. The connecting block 10 restricts the button 13 to only slide horizontally. The outside of the card block 11 is slidably connected to the connecting block 10. The connecting block 10 can restrict the positioning block 4 to keep its position relatively fixed. The outside of the connecting block 10 is slidably connected to the upper inside of the positioning rod 5. A vertical groove is opened in the upper part of the positioning rod 5 to position the connecting block 10. A bolt 9 is rotatably connected to the right part of the connecting block 10. The outside of the bolt 9 is threadedly connected to the positioning block 4. The rotation of the bolt 9 can finely adjust the position of the positioning block 4, so that PCB boards of different sizes can be clamped and positioned. The lower part of the positioning block 4 is slidably connected to the upper inside of the connecting block 10. A de-positioning component is arranged on the upper part of the base 1.

[0031] Refer to Figure 1 - Figure 2, the unlocking component includes a fixed rod 2. The fixed rod 2 can restrict the extrusion rod 3 to maintain a horizontal and fixed state. The side of the fixed rod 2 is in contact with the side of the extrusion rod 3 and the outer side of the end of the positioning rod 5. The side end of the fixed rod 2 is fixedly connected to the extrusion rod 3. The lower end of the extrusion rod 3 is an inclined surface. The inclined surface extrusion can make the button 13 slide into the inside of the connecting block 10. In this way, the limit of multiple groups of connecting blocks 10 can be unlocked simultaneously, increasing the convenience of disassembling the connecting block 10. The lower part of the fixed rod 2 is elastically connected to the top of the base 1 through the second spring 8. The extrusion of the second spring 8 can make the fixed rod 2 slide upward. One end of the second spring 8 is fixedly connected to the top of the base 1. The second spring 8 is kept in a state of extruding the fixed rod 2 under the extrusion of the top of the base 1. The other end of the second spring 8 is fixedly connected to the lower part of the fixed rod 2. A fixed column 7 is slidably connected inside the fixed rod 2. The fixed column 7 can restrict the fixed rod 2 to slide vertically only within a fixed distance. The lower part of the fixed column 7 is fixedly connected to the top of the base 1.

[0032] Working principle: By vertically sliding, the connecting block 10 can slide into the inside of the vertical groove, and the lower inclined surface of the clamping block 11 is extruded by the upper end of the vertical groove and slides into the inside of the connecting block 10 to extrude the first spring 14. Subsequently, the clamping block 11 slides into the inside of the clamping groove 6 under the extrusion of the first spring 14 to fix the connecting block 10. According to the four corners of the PCB board, multiple groups of connecting blocks 10 are clamped. Subsequently, the bolt 9 is rotated. The rotation of the bolt 9 can extrude the positioning block 4 to move horizontally for fine adjustment, facilitating the clamping and positioning of PCB boards of different sizes. Subsequently, the PCB board can be placed on the upper part of the positioning block 4 for feeding. Subsequently, the base 1 is lifted by the lead screw device, driving the PCB board to slide upward for feeding. Subsequently, the base 1 slides downward. When the connecting block 10 needs to be disassembled, the fixed rod 2 can be slid downward to squeeze the second spring 8. The fixed rod 2 drives the extrusion rod 3 to slide downward. The lower inclined surface of the extrusion rod 3 extrudes the button 13 to make it slide into the inside of the connecting block 10. The button 13 drives the inclined surface block 12 to slide. The inclined surface block 12 extrudes the clamping block 11 to slide into the inside of the connecting block 10 to extrude the first spring 14. Subsequently, the connecting block 10 can be slid upward for disassembly. After the connecting block 10 slides out of the vertical groove, the clamping block 11 slides out under the extrusion of the first spring 14, and the inclined surface block 12 and the button 13 slide back to their original positions. The fixed rod 2 is released. At this time, the second spring 8 extrudes the fixed rod 2 so that the fixed rod 2 and the extrusion rod 3 slide upward until they are restricted by the fixed column 7 and stop sliding.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
