[0025] The cache mechanism 4 includes two groups of symmetrically arranged limit members 41, which are respectively arranged at the front end and the rear end of the housing 1. The two groups of limit members 41 are respectively arranged at opposite sides thereof, and a plurality of limit grooves 411 are arranged at intervals along the vertical direction. Each group of limit members 41 is provided with a through groove 42 along the vertical direction.

[0026] The feeding mechanism 3 is arranged between the feed port 11 and the discharge port 12. The feeding mechanism 3 includes a cylinder 31. The output end of the cylinder 31 is connected to a mounting plate 32. A roller 33 is rotatably connected to the mounting plate 32. A first motor 34 is provided on the mounting plate 32 for driving the roller 33 to rotate. The roller 33 is arranged in a through groove 42. The cylinder 31 drives the mounting plate 32 to move in a horizontal direction so that the roller 33 moves to the bottom of the limiting groove 411.

[0027] Specifically, each group of limiting members 41 is composed of a plurality of sheet-like limiting blocks arranged at intervals, and the intervals between adjacent sheet-like limiting blocks constitute a through slot 42; a roller 33 is provided in each through slot 42, and a single group of rollers 33 is driven by a sprocket and a chain with the first motor 34, so that the first motor 34 can drive multiple rollers 33 to rotate synchronously.

[0028] The lifting mechanism 2 includes a second motor 21 and a first guide rod 22 fixed in the casing 1. The conveying end of the second motor 21 is connected to a first screw rod 23 arranged parallel to the first guide rod 22; the first guide rod 22 extends in the vertical direction, and a slide plate 24 is slidably connected to the first guide rod 22, and the slide plate 24 is provided with a first nut 25 adapted to the first screw rod 23.

[0029] The feeding mechanism 3 is provided with two groups corresponding to the two groups of limit members 41 one by one; the feeding mechanism 3 also includes a second guide rod 35 fixedly connected to the housing 1, the second guide rod 35 is extended in the horizontal direction, a slider 36 is slidably connected to the second guide rod 35, the cylinder 31 is mounted on the slider 36, and the mounting plate 32 is slidably connected to the second guide rod 35.

[0030] The cache mechanism 4 also includes a frame 43 and a third motor 44 fixed on the slide 24. The output end of the third motor 44 is connected to a second screw rod 45 in a transmission manner. The second screw rod 45 is arranged in parallel with the second guide rod 35. The first set of stoppers 41 is fixed in the frame 43. The second set of stoppers 41 is slidably connected with the second guide rod 35. The second set of stoppers 41 is provided with a second nut 46 adapted to the second screw rod 45. Specifically, a second screw rod 45 is correspondingly arranged on each of the four side lines of the frame 43. Similarly, the plurality of second screw rods 45 are connected to the third motor 44 through a sprocket and a chain, so that the third motor 44 can drive the plurality of second screw rods 45.

[0031] When the third motor 44 is working, it drives the second screw rod 45 to rotate, and drives the second nut 46, so that the second set of limit members 41 slides relative to the second guide rod 35, and the second set of limit members 41 moves closer to or farther from the first set of limit members 41, thereby adjusting the distance between the two sets of limit members 41, which can be used for caching PCB boards of different specifications and widths, and has a wider range of applications. When the second set of limit members 41 moves relatively, the feeding mechanism 3 connected thereto will also move together.

[0032] Each set of limiting members 41 is provided with a third guide rod 47 , which is arranged parallel to the first guide rod 22 , and the slider 36 is slidably connected to the third guide rod 47 , which can ensure that the limiting members 41 are stable and reliable during the lifting process.

[0033] A first fan 5 is provided on the top of the housing 1, and a second fan 26 is provided on the slide plate 24. The first fan 5 and the second fan 26 are both arranged relative to the cache mechanism 4.

The warning light 6, the first fan 5, the lifting mechanism 2, the cache mechanism 4 and the feeding mechanism 3 are electrically connected to the controller respectively; the four corners of the bottom of the housing 1 are respectively provided with support feet 7.

[0034] The specific working principle of the utility model is as follows: before the PCB board enters the casing 1 from the feed inlet 11, the lifting mechanism 2 will work first, and the second motor 21 will drive the first screw rod 23 to rotate, and drive the first nut 25, so that the slide plate 24 slides up and down along the first guide rod 22, driving the entire cache mechanism 4 to move, until the cache mechanism 4 reaches the specified position, so that the empty limit groove 411 is located between the feed inlet 11 and the feed inlet 12, and is located above the roller 33; then the feeding mechanism 3 works, the cylinder 32 drives the mounting plate 32 to extend, so that the roller 33 is located below the empty limit groove 411, and the first motor 34 will also work to drive the roller 33 to rotate. At this time, the PCB board enters the casing 1 from the feed inlet 11, and under the action of the roller 33, the PCB board is stored between the limit grooves 411. After the PCB board is in place, the cylinder 32 drives the mounting plate 32 to retract, and the roller 33 also retracts, and will not contact the PCB board, thus completing the cache of a PCB board;

[0035] Next, wait for the relevant problems to be processed until the controller receives the instruction to discharge the material. Similarly, the lifting mechanism 2 will work first to move the PCB board that enters first to between the feed port 11 and the feed port 12, and the feeding mechanism 3 will work to send the PCB board out. The specific working process is described above and will not be repeated here. By working in this way in a cycle, the first-in-first-out of the PCB board can be achieved.
