[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0024] like Figure 1 As shown, the circuit board temporary storage conveyor line provided by the present invention includes a rack 100, a cache roller conveyor line 200, a lifting temporary storage rack 300, a first roller conveyor line 400, a second roller conveyor line 500 and a lifting roller conveyor line 600. The cache roller conveyor line 200 is installed on the rack 100, and the lifting temporary storage rack 300 has a plurality of temporary storage ends arranged in sequence along the vertical direction. Each temporary storage end is slidably connected to the rack 100 in the vertical direction and can pass through the cache roller conveyor line 200. The first roller conveyor line 400 is installed on the rack 100 and is arranged in the same line with the cache roller conveyor line 200. The second roller conveyor line 500 is installed on the rack 100 and is located between the cache roller conveyor line 200 and the first roller conveyor line 600.

The lifting conveying end can move to a position opposite to the cache roller conveyor line 200 and the first roller conveyor line 400, or move to a position lower than the top of the second roller conveyor line 500.

[0025] During implementation, when the circuit board is located above the lifting conveyor line, the circuit board can be made to fall on the second roller conveyor line 500 or the lifting conveyor line by adjusting the vertical height of the lifting conveyor end. When the circuit board falls on the second roller conveyor line 500, the circuit board can be output in two directions by controlling the conveying direction of the second roller conveyor line 500. When the circuit board falls on the lifting conveyor line, the lifting conveyor line can convey the circuit board to the first roller conveyor line 400 or the buffer roller conveyor line. In summary, the circuit board temporary storage conveyor line can receive and store circuit boards conveyed from three directions (the direction of the first roller conveyor line 400 away from the lifting temporary storage rack 300 and the forward and reverse conveying directions of the second roller conveyor line 500), or convey the stored circuit boards in three directions, which can match the stocking requirements of multiple processes.

The multiple third wheel rows 620 are arranged in sequence along the length direction of the third support frame 610 and are all rotatably connected to the third support frame 610. The tops of the multiple third wheel rows 620 form a lifting conveying end.

When the circuit board falls on the second roller conveyor line 500, the circuit board can be output in two directions by controlling the conveying direction of the second roller conveyor line 500. When the circuit board falls on the lifting conveyor line, the lifting conveyor line can convey the circuit board to the first roller conveyor line 400 or the buffer roller conveyor line. In summary, the circuit board temporary storage conveyor line can receive and store circuit boards conveyed in three directions (the direction of the first roller conveyor line 400 away from the lifting temporary storage rack 300 and the forward and reverse conveying directions of the second roller conveyor line 500), or convey the stored circuit boards in three directions, which can match the stocking requirements of multiple processes.
