For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] refer to Figure 1-7 An embodiment of the present application shows a circuit board blind hole drilling positioning mechanism, including a support platform 1, two driving mechanisms 3, and a visual component 2. The support platform 1 is provided with two vertically arranged fixed baffles 11 and two vertically arranged movable baffles 12. The two movable baffles 12 are movably arranged on the support platform 1. A clamping space (not marked in the figure) for placing a circuit board 100 is formed between the two fixed baffles 11 and the two movable baffles 12. A detection hole 13 vertically penetrating the support platform 1 is formed at the intersection of the two fixed baffles 11, and the side of the detection hole 13 is connected to the clamping space; the two driving mechanisms 3 respectively drive the two movable baffles 12 to move; the visual component 2 is arranged under the support platform 1 and is used to detect the detection hole 13.

[0033] Specifically, after the circuit board 100 is placed in the clamping space, the driving mechanism 3 drives the movable baffle 12 to move, and the two fixed baffles 11 and the two movable baffles 12 clamp and fix the four sides of the circuit board 100. The visual component 2 detects from the lower end of the detection hole 13. When the circuit board 100 is accurately positioned, a corner of the circuit board 100 will enter the detection hole 13, thereby being detected by the visual component 2. After the detection is passed, the corresponding drilling device will perform blind hole drilling processing; when the positioning of the circuit board 100 is deviated, the visual component 2 does not detect the circuit board 100 in the detection hole 13, and will not perform the next step of blind hole drilling processing to avoid the production of defective products.

[0034] For details of the above scheme, please refer to Figure 3 The visual component 2 includes a mounting frame 21, a light source 22, a lens 23 and an industrial camera 24, wherein the light source 22, the lens 23 and the industrial camera 24 are all arranged on the mounting frame 21, and the mounting frame 21 is detachably connected to the support platform 1.

[0035] In some embodiments, reference Figure 1 The support platform 1 is provided with a guide rail 14, and the movable baffle 12 is slidably arranged on the guide rail 14. The guide rail 14 provides a guiding function, and on the basis of the power provided by the driving mechanism 3, improves the stability of the movable baffle 12 when it moves.

[0036] For details of the above scheme, please refer to Figure 6 and Figure 7 , the guide rail 14 passes through the support platform 1 from top to bottom, the driving mechanism 3 includes a cylinder 31 disposed below the support platform 1, a piston end of the cylinder 31 is connected to a connecting block 32, and the movable baffle 12 is disposed above the support platform 1 and connected to the connecting block 32. In this embodiment, the cylinder 31 is disposed at the bottom of the support platform 1, so that the structure above the support platform 1 can be more streamlined, avoiding interference with other components such as a manipulator and a drill bit when working together.

[0037] Specifically, the guide rails 14 are provided with at least two, the top of the connection block 32 is provided with a protrusion 321 passing through the guide rails 14, the protrusion 321 is connected to a mounting plate 33, a guide rod 34 is sleeved on the mounting plate 33 along the lateral sliding, the movable baffle 12 is fixed to one end of the guide rod 34, the other end of the guide rod 34 is fixed to a limit block 341, a spring 35 is sleeved on the guide rod 34, and the spring 35 is arranged between the movable baffle 12 and the mounting plate 33. The spring 35 is used to provide a flexible buffer for the movable top plate to prevent the cylinder 31 from damaging the circuit board 100 when driving the movable baffle 12 to move.

[0038] In some embodiments, reference Figure 5-7The fixed baffle 11 is provided with a first guide slope 111 at its lower portion, and the angle between the first guide slope 111 and the upper surface of the support platform 1 is 50-70°; the movable baffle 12 is provided with a second guide slope 121 at its lower portion, and the angle between the second guide slope 121 and the upper surface of the support platform 1 is 50-70°. In this embodiment, by providing the first guide slope 111 and the second guide slope 121, when the movable baffle 12 pushes and clamps the circuit board 100, a downward separation of the circuit board 100 is generated, so that the circuit board 100 can be kept close to the upper surface of the support platform 1, so that the circuit board 100 is stably placed flat, and the processing stability is improved.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
