Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: a circuit board processing and testing platform provided with a through-beam optical fiber sensor, comprising a frame 1, a conveyor belt 101 installed on the frame 1, and two sets of workbenches 102 connected to the frame 1, two sets of electric push rods are connected above the frame 1, and the output ends of the two sets of electric push rods are both connected to the through-beam optical fiber sensor body 2;

[0026] Two sets of fixed platforms 3 are connected to the frame 1, and a push plate 4 is slidably connected between the two sets of fixed platforms 3. A driving mechanism for pushing the push plate 4 to reciprocate and move horizontally is provided on the frame 1. Four sets of limit rods 503 are slidably connected inside the frame 1, and one end of any limit rod 503 is connected to a plate 502. A movable mechanism is commonly connected above every two sets of plates 502. Through the operation of the driving mechanism in conjunction with the two sets of movable mechanisms, the circuit board can be processed and inspected in an assembly line manner, which greatly improves the original inspection efficiency and reduces the workload of workers.

[0027] See also Figure 1 , Figure 2 and Figure 3 , the driving mechanism includes a motor, a rotating rod 401, a gear 402, a gear ring 403 and a side rod 404;

[0028] A motor is connected to the frame 1, and a rotating rod 401 is inserted into the output end of the motor. The other end of the rotating rod 401 is rotatably connected to the frame 1. A gear 402 is sleeved on the rotating rod 401, and a gear ring 403 is meshed on the outside of the gear 402. The top of the gear ring 403 is connected to the bottom end of the push plate 4. By providing a driving mechanism, the push plate 4 can push the circuit board to the two groups of workbenches 102 one after the other, so that the two groups of opposing optical fiber sensor bodies 2 can detect the circuit board, thereby improving the detection efficiency of the circuit board.

[0029] See also Figure 1 and Figure 3 The left and right ends of the gear ring 403 are connected to side rods 404, and the two sets of side rods 404 are slidably connected to the inside of the frame 1. The side rods 404 can support and limit the gear ring 403.

[0030] See also Figure 1 and Figure 4 , the movable mechanism includes a cylinder, a connecting block 5 and a connecting rod 501;

[0031] A cylinder is connected to the frame 1, and a connecting block 5 is connected to the output end of the cylinder. Both the left and right ends of the connecting block 5 are rotatably connected to connecting rods 501. The end of each set of connecting rods 501 away from the connecting block 5 is rotatably connected to the top of the plate 502. By controlling the cylinder, the two sets of plates 502 can play a secondary positioning role on the circuit board, thereby improving the stability of the circuit board during detection on the surface of the workbench 102.

[0032] See also Figure 2 Two groups of discharge plates 504 are connected to the frame 1, and one end of each group of discharge plates 504 is connected to the outer wall of the workbench 102. One end of each group of discharge plates 504 close to the workbench 102 is in contact with the bottom end of any plate 502. By providing the discharge plates 504, the circuit boards that have been inspected can be discharged.

[0033] See also Figure 1 and Figure 5 There are four groups of movable rods 6 movably connected inside the frame 1, one end of each group of movable rods 6 is connected to a guide block 601, the bottom end of each group of guide blocks 601 is attached to the surface of any workbench 102, one end of each group of movable rods 6 away from the guide block 601 is connected to a spring 602, and the other end of each group of springs 602 is connected to the frame 1. Through the cooperation of the movable rods 6, the guide blocks 601 and the springs 602, the circuit board can be initially limited when entering the surface of the workbench 102.

[0034] See also Figure 5 One end of any guide block 601 is set to be inclined, and every two groups of guide blocks 601 cooperate with each other to guide the circuit board.

[0035] Working principle: First, by starting the motor, the rotating rod 401 drives the gear 402 to rotate, so that the gear 402 drives the gear ring 403 to move, and the movement of the gear ring 403 drives the two sets of side rods 404 to move on the frame 1, and the gear ring 403 drives the push plate 4 to move on the fixed table 3 synchronously, and then the workers place the circuit boards on the surface of the conveyor belt 101 one by one for transmission. Under the action of the conveyor belt 101, the circuit boards are transmitted to the surface of the fixed table 3, so as to push the circuit boards moved to the surface of the fixed table 3, so that the two circuit boards can be respectively entered along the fixed table 3 into the surface of the two sets of workbenches 102 for detection operation;

[0036] When the circuit board moves from the surface of the fixed table 3 to the surface of the workbench 102, the side wall of the circuit board will squeeze the guide block 601, so that the movable rod 6 moves inside the frame 1, and then the spring 602 is elastically deformed, so that the two groups of guide blocks 601 are squeezed by the circuit board and move on the surface of the workbench 102, which plays a preliminary positioning role for the circuit board, and prevents the circuit board from tilting under the through-beam optical fiber sensor body 2 and affecting the detection of the through-beam optical fiber sensor body 2;

[0037] After the circuit board is positioned by the guide block 601, it moves to the surface of the workbench 102, below the main body 2 of the through-beam optical fiber sensor. By driving the cylinder, the connecting block 5 is lifted longitudinally, thereby driving the plate 502 connected to the connecting rod 501 to move on the surface of the workbench 102, so that the limiting rod 503 slides inside the frame 1 until the inner walls of the two groups of plates 502 are attached to the outer wall of the circuit board, and the circuit board can be stabilized below the main body 2 of the through-beam optical fiber sensor. Then the driving cylinder can be stopped, and then the electric push rod is driven to drive the main body 2 of the through-beam optical fiber sensor to move, so as to detect the circuit board. After the detection is completed, the cylinder is driven so that the two groups of plates 502 no longer limit the circuit board. Under the guidance of the discharge plate 504, the circuit board that has been detected can move along the discharge plate 504 and leave the surface of the workbench 102, so that it is convenient for workers to collect it.

[0038] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
