Description

Technical Field

[0001] This utility model relates to the field of circuit board surface mount technology, specifically to an adjustable tray for circuit board surface mount. Background Technology

[0002] A circuit board, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for the electrical interconnection of these components. Wherever there are electronic components such as integrated circuits, circuit boards are used to enable electrical interconnection between these components. PCB surface mount technology (SMT) is the process of mounting components onto the outside of the board, and trays are used in this process.

[0003] Most of the trays on the market that are based on circuit board surface mount technology (PCB) are integrated structures, and the size of their internal surface mount slots cannot be changed. When the specifications of the circuit board being processed are changed, a corresponding tray needs to be replaced so that the two can be used together, which limits their use.

[0004] Therefore, we proposed an adjustable tray for circuit board surface mount to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable tray for circuit board mounting, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: An adjustable tray for circuit board surface mount includes a base with a placement slot. The left and right side walls of the placement slot have strip-shaped holes. A horizontal bar is movably arranged in the placement slot, and wing bolts are installed at both ends of the horizontal bar. The wing bolts pass through the strip-shaped holes to secure the horizontal bar in the placement slot. Threaded guide rods are embedded in the upper and lower side walls of the placement slot, and vertical bars are movably fitted on the threaded guide rods. Limit nuts are threadedly connected to the threaded guide rods, and the limit nuts are located on both sides of the vertical bars. The vertical bars and horizontal bars are arranged in a vertically staggered pattern.

[0007] Furthermore, the two ends of the crossbar are provided with openings, and the openings are provided with slots, and the tail end of the wing bolt is installed in the slot.

[0008] Furthermore, the head end of the wing bolt protrudes outward from the strip hole, and the nut thereon is fastened to the head end of the bolt.

[0009] Furthermore, the upper and lower side walls of the placement groove are provided with mounting positions, and the threaded guide rod is embedded in the mounting position.

[0010] Furthermore, the horizontal bar is provided with a relief groove, and the vertical bar rests on the relief groove.

[0011] Furthermore, the vertical strips are provided with clearance notches, and the clearance notches correspond to the positions of the horizontal strips.

[0012] Compared with the prior art, the present invention provides an adjustable tray for circuit board mounting, which has the following advantages: This invention allows for flexible adjustment of the tightness of the horizontal bar by rotating the nut on the wing bolt. With the cooperation of the strip hole, the horizontal bar can be moved along the trajectory of the strip hole, thereby adjusting the position of the horizontal bar in the placement groove. By tightening the limiting nuts on both sides of the vertical bar, the vertical bar can be moved along the trajectory of the threaded guide rod, thereby adjusting the position of the vertical bar in the placement groove, thus changing the capacity of the internal slot. In this way, it can accommodate circuit boards of different sizes for surface mount processing. The overall structure is simple and easy to implement. Attached Figure Description
