[0002] In the manufacturing process of printed circuit board, there are multiple high-temperature baking processes. In the prior art, the baking of printed circuit board is mainly through stacking placement. Due to the action of gravity and inertia, the stacked printed circuit board is prone to relative displacement during circulation, which causes surface scratches and affects the appearance or performance of the product. However, different baking fixtures are required for different specifications of circuit boards, and the replacement of different baking fixtures results in waste of time and labor costs.

[0003] In order to solve the above problems, the Chinese patent with publication number CN219322683U discloses a circuit board baking forming tool, which includes a base, a guide rail, an adjustable baffle, a fixed baffle, a fixed slot plate, a left end slot, a spacing adjustment assembly, a clamping block, and a right end slot. The application can adjust the spacing between the clamping block and the fixed baffle through the spacing adjustment assembly. The detachably connected fixed slot plate can be replaced in time, and different clamping blocks can be replaced to fix circuit boards of different thicknesses. The arrangement of multiple spacing adjustment assemblies and multiple left end slots allows the spacing between the corresponding left end slots and right end slots to be adjusted individually, thereby allowing circuit boards of different specifications to be baked in one baking process.

[0004] The above-mentioned technical disclosure of a circuit board baking forming tool can separate and clamp multiple circuit boards by individually adjusting the positions of multiple mounting seats and top seats. The fixed slot plate can be disassembled and replaced to accommodate circuit boards of different thicknesses. However, the following deficiencies exist during use: 1. The method of adjusting multiple top seats one by one to clamp multiple circuit boards cannot clamp multiple circuit boards simultaneously, is tedious and time-consuming to operate, has low work efficiency, and cannot meet the demand for quickly separating and fixing multiple circuit boards; 2. The method of disassembling and replacing the fixed slot plate requires multiple fixed slot plates and requires frequent replacement, which is tedious to operate and cannot conveniently adjust the insertion spacing according to circuit boards of different thicknesses, resulting in unsatisfactory convenience.
