Description

Technical Field

[0001] The present invention relates to the technical field of SMT processing equipment, and in particular to a lifting circuit board buffer device and SMT processing equipment. Background Art

[0002] SMT (Surface Mounted Technology) processing equipment is a type of industrial equipment that performs surface mounting on circuit boards. SMT processing equipment is widely used in aerospace, automotive, computer, digital product, communications equipment, and precision instrumentation. SMT processing equipment consists of a lifting circuit board buffer and a main body. The main body has a storage cavity, and the lifting circuit board buffer is located within the cavity and connected to the main body.

[0003] In the prior art, a lifting circuit board buffer device includes a feeding assembly, a lifting mechanism and a blanking assembly. The lifting mechanism is located between the feeding assembly and the blanking assembly. The lifting mechanism is provided with multiple buffer components (i.e., conveying mechanisms), and the multiple buffer components are arranged at intervals. For example, a traditional lifting-type circuit board cache device, such as the Chinese patent with patent number CN202123326386.X, proposes a circuit board cache device for SMT patches, including a storage box and a lifting mechanism. The storage box is provided with an input port and an output port. The input port is connected to the reflow soldering equipment, and the output port is connected to the detection equipment. A multi-layer conveying mechanism is provided in the storage box, and the lifting mechanism is connected to the storage box. The lifting mechanism is used to drive the storage box to move in the vertical direction. The lifting mechanism is coupled with an infrared sensing circuit for controlling the start and stop of the lifting mechanism. When the input port senses the SMT circuit board, the lifting mechanism is energized and the storage box moves downward as a whole. When the output port senses the SMT circuit board, the lifting mechanism is started and the storage box moves upward as a whole, so that the circuit board cache device for SMT patches can store multiple circuit boards to prevent multiple circuit boards from being stacked together, thereby improving production efficiency.

[0004] However, since the sizes of the input port and the output port are fixed, the circuit boards are respectively adapted to the input port and the output port, so that the width of the circuit board is fixed, and thus the width of each conveying mechanism is fixed, so that each conveying mechanism can only adapt to circuit boards of the same width, resulting in each conveying mechanism being unable to adapt to circuit boards of multiple different widths, thereby making the adaptability compatibility of each conveying mechanism poor, and further making the adaptability compatibility of the circuit board cache device for SMT patches poor, that is, making the adaptability compatibility of the lifting circuit board cache device poor. In addition, each conveying mechanism is provided with a horizontally parallel conveyor belt, each conveyor belt is used to cache circuit boards, and the lifting mechanism is used to drive the storage box to move in the vertical direction, that is, the lifting mechanism is used to drive each circuit board to move in the vertical direction. Since each conveyor belt is not provided with a structure for fixing the position of the circuit board, each conveyor belt is more likely to vibrate during the vertical movement, causing each circuit board to be more likely to deviate during the vertical movement, making each circuit board more likely to deviate from the cache position of the corresponding conveyor belt, causing one end of each circuit board to separate from the corresponding conveyor belt, thereby making each circuit board more likely to fall off from the corresponding conveying mechanism, making each circuit board more likely to fall off from the SMT patch circuit board cache device, and then making the SMT patch circuit board cache device have poor position fixation for each circuit board, that is, making the lifting circuit board cache device have poor position fixation for each circuit board.
