[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The embodiment of the present application provides a marking device for PCB board inspection, which solves the problem in the prior art that different models of PCB boards have different thicknesses, and the robot arm and the marking pen often apply too much pressure when marking thicker PCB boards during the marking process. On the one hand, this may cause damage to the end of the marking pen and unclear subsequent markings, and on the other hand, it may also cause damage to the surface of the PCB board, affecting product quality.
[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] The utility model embodiment discloses a marking device for PCB board detection. Figure 1-4 As shown, it includes a mechanical arm body 1 arranged on a detection equipment frame, an axle seat 2 is arranged on the mechanical arm body 1, a main shaft 3 is rotatably connected to the axle seat 2, an angle limit buffer mechanism is arranged between the main shaft 3 and the axle seat 2, a support 5 is arranged on the main shaft 3, and a marker pen body 7 is movably connected inside the support 5;
[0025] The angle limit buffer mechanism comprises a buffer plate 4 arranged on the main shaft 3 and a baffle 403 arranged inside the shaft seat 2. A notch 401 is arranged on the buffer plate 4. A spring 402 is fixedly connected between the baffle 403 and the inner wall of the notch 401.
[0026] The device is designed with an angle limit buffer mechanism, so that when the robot arm body 1 drives the support 5 and the marker pen body 7 to move and mark the PCB board, there is a buffer force between the marker pen body 7 and the PCB board, which avoids the phenomenon that the PCB board or the marker pen body 7 is damaged due to excessive force. The device is suitable for marking PCB boards of greater thickness. Through the design of the main shaft 3, the shaft seat 2 and the angle limit buffer mechanism, the marker pen body 7 is in an inclined state, the force on the marker pen body 7 is more stable, and the marking effect on the PCB board is better.
[0027] When the robot arm body 1 drives the support 5 and the marker pen body 7 to move and mark the PCB board, when the marker pen body 7 contacts and generates pressure on the PCB board, the pressure will drive the marker pen body 7 and the support 5 to move, so that the support 5 drives the main shaft 3 to slightly deflect along the shaft seat 2, and the main shaft 3 drives the buffer plate 4 to move, and the notch 401 of the buffer plate 4 squeezes the spring 402, so that the spring 402 is further compressed to form a buffer at the position of the marker pen body 7.
[0028] Both ends of the support 5 are provided with clamping components for limiting the position of the marker pen body 7; the clamping component includes a clamping seat 6 connected to the support 5, and the clamping seat 6 is movably clamped with a clamping block 604 inside. The marker pen body 7 is clamped between two groups of clamping blocks 604, and an adjusting seat 601 is fixedly connected to the clamping seat 6, and a slider 602 is slidably connected to the inside of the adjusting seat 601. The slider 602 is fixed to the clamping block 604, and a double-threaded screw 603 is rotatably connected to the adjusting seat 601, and the double-threaded screw 603 is threadedly connected to the slider 602.
[0029] The device is designed with a clamping component so that the marker pen body 7 is easy to replace. When the marker pen body 7 is loaded, the marker pen body 7 is clamped between the support 5 and the clamping seat 6, and then the double-threaded screw 603 is rotated to make the double-threaded screw 603 drive the two sets of sliders 602 to move towards each other, and the slider 602 drives the clamping block 604 to move, and the clamping block 604 finally achieves the clamping and limiting of the marker pen body 7.
[0030] A rotating handle 605 is fixedly connected to the double-threaded screw 603, and a slot corresponding to the marker pen body 7 is provided on the clamping seat 6 and the support 5. An arc groove corresponding to the marker pen body 7 is provided on the clamping block 604, and a rubber pad is provided inside the arc groove. The design of the rotating handle 605 makes it easy and labor-saving to rotate the double-threaded screw 603. The slot design of the clamping seat 6 and the support 5 makes it easy to install and position the marker pen body 7. The arc groove and rubber pad design on the clamping block 604 make it stable and not easy to loosen when the marker pen body 7 is clamped and positioned.
