Description

Technical Field

[0001] This utility model relates to the field of circuit board surface mount technology, and in particular to an SMT printed circuit board surface mount tray. Background Technology

[0002] PCB, short for Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and provides electrical connections. Because it is manufactured using surface mount technology (SMT), it is called a "printed" circuit board. When mounting PCBs using a pick-and-place machine, a special tray is used to attach and fix the PCB to the tray using glue or tape.

[0003] However, existing circuit board placement trays cannot fix multiple circuit boards at the same time. When placing circuit boards, after one circuit board is placed, the completed circuit board needs to be removed and other circuit boards need to be fixed and placed again, which is time-consuming, labor-intensive and reduces the efficiency of circuit board placement.

[0004] Therefore, it is necessary to provide an SMT printed circuit board placement tray to solve the above-mentioned technical problems. Utility Model Content

The housing 45 is fixedly connected to the tray body 2.

[0031] The clamping module 1 includes a second motor 112, which is fixedly connected to the upper side of the tray body 2. The output shaft of the second motor 112 passes through the tray body 2, and the end of the output shaft of the second motor 112 is fixedly connected to the center of a first bevel gear 110. The first bevel gear 110 meshes with a set of second bevel gears 111, and the central shaft of the set of second bevel gears 111 is movably connected to the housing 45.
