The circuit board 1 is disposed on the base 2, the coating stencil plate 3 is disposed on the side of the circuit board 1 away from the base 2, and the pressure plate 4 is disposed on the side of the coating stencil plate 3 away from the circuit board 1.
[0034] The base 2 and the pressure plate 4 can be attracted together.
[0035] In this embodiment, a robotic circuit board stencil fixture is used to apply solder paste to a circuit board 1. The robotic circuit board stencil fixture includes a base 2, a coating stencil 3, and a pressure plate 4. In this embodiment, the circuit board 1 is placed on the base 2, the coating stencil 3 is placed on the side of the circuit board 1 away from the base 2, and the pressure plate 4 is placed on the side of the coating stencil 3 away from the circuit board 1. Since the base 2 and the pressure plate 4 can be attracted together, the circuit board 1 and the coating stencil 3 can be quickly clamped between the base 2 and the pressure plate 4, thus improving work efficiency.
[0036] This utility model's robot circuit board stencil fixture has a simple structure, quickly fixing and coating the stencil plate 3 and circuit board 1. Unlike traditional stencil fixtures, which are complex in structure, cumbersome in operation, and require multiple clamping adjustments, this utility model's robot circuit board stencil fixture uses only the base 2 and pressure plate 4 as its main structural components. It utilizes the suction between the base 2 and pressure plate 4 to quickly coat the stencil plate 3 and circuit board 1, resulting in a simple structure and convenient operation.
[0037] In some embodiments, the base 2 has a first positioning groove 21 adapted to the coating screen 3 on the side facing the pressure plate 4, the coating screen 3 is disposed in the first positioning groove 21, and the circuit board 1 is clamped between the bottom of the first positioning groove 21 and the coating screen 3.
[0038] In this embodiment, a first positioning groove 21 adapted to the coating stencil 3 is constructed on the side of the base 2 facing the pressure plate 4. The circuit board 1 is placed at the bottom of the first positioning groove 21, and the coating stencil 3 is quickly placed in the first positioning groove 21, thereby achieving rapid positioning of the coating stencil 3 and improving work efficiency.

[0043] In some embodiments, the bottom of the first positioning groove 21 is provided with a first mounting hole 212, and a first magnetic attracting member 5 is provided in the first mounting hole 212. When the pressure plate 4 is made of iron, it can be attracted to the pressure plate 4 by the first magnetic attracting member 5 in the first mounting hole 212 at the bottom of the first positioning groove 21 on the base 2, thereby realizing the attraction between the base 2 and the pressure plate 4.
[0044] In some embodiments, the pressure plate 4 has a second mounting hole 42 on the side facing the coating mesh plate 3, and a second magnetic member 6 is provided in the second mounting hole 42.

Solder paste is applied to the circuit board 1 through the clearance hole 41 and the plurality of mesh holes 31 of the coating stencil 3.
[0046] First mounting holes 212 can be constructed at the four corners of the bottom of the first positioning groove 21, and a first magnetic suction member 5 can be provided in each first mounting hole 212. Second mounting holes 42 can be constructed at the four corners of the pressure plate 4, and a second magnetic suction member 6 can be provided in each second mounting hole 42.
