Description

Technical Field

[0001] The utility model relates to the technical field of PCBA burning, and in particular to a PCBA burning fixture. Background Art

[0002] In the PCBA manufacturing industry, a programming jig is an important auxiliary device for programming software into PCBAs. Currently, a simplified programming jig on the market typically consists of a bracket fixed to a base plate, a pressure plate connected to the bracket by a push-pull clamp mechanism, and a PCBA carrier plate mounted on the base plate below the pressure plate. The PCBA carrier plate is equipped with slots for mounting and securing the PCBA, while the pressure plate is fixed with several downward-pointing programming pins. During use, the push-pull clamp mechanism is used to push the pressure plate downward, causing the programming pins to align with the programming terminals on the PCBA below, allowing subsequent program programming to be completed.

[0003] In the prior art, the patent document with the announcement number CN217372046U proposes a jig for PCBA program burning, which includes a bottom plate, a top plate and a placement plate arranged on the bottom plate. The placement plate is provided with a threaded sleeve, a turning handle, a movable plate and a movable rod to drive the adjustment of the position of the fixed component on the placement plate, and cooperates with the sliding rod and the clamping component to clamp the side of the PCBA board. The position of the clamping component on the sliding rod is adjustable, so that the clamping component can clamp PCBA boards of different sizes and types, and cooperates with the telescopic parts and the burning plate set on the top plate to burn the PCBA board, which is more convenient and flexible to use.

[0004] In order to solve the problem that the existing burning jig cannot clamp different types of PCBA boards and the installation and removal of PCBA boards are relatively inconvenient, the existing technology adopts a method of adjusting the position of the fixing component on the placement plate by providing a threaded sleeve, a turning handle, a movable plate and a movable rod, and clamping the side of the PCBA board with a sliding rod and a clamping component. However, the jig still has the problem of being inconvenient to flexibly adjust the position of the PCBA board during use, which reduces the practicality of the burning jig. Utility Model Content
