[0032] See also Figure 1-7 The utility model provides a technical solution: a circuit board sorting and unloading conveyor line, comprising:

[0033] The first conveying mechanism includes a first positioning seat 1, a first driving roller 2, and a first conveying belt 3 sleeved on the surfaces of the first positioning seat 1 and the first driving roller 2, and at least one of the first driving rollers 2 is connected to a rotation driving device;

[0034] The second conveying mechanism includes a second positioning seat 10, a second driving roller 11, and a second conveying belt 12 sleeved on the surface of the second positioning seat 10 and the second driving roller 11, and at least one of the second driving rollers 11 is connected to a rotation driving device;

[0035] The material distribution mechanism includes a rotating shaft 4 and a swing plate 5 extending from the side of the rotating shaft 4, and the rotating shaft 4 is connected to the rotary drive device;

[0036] The guiding mechanism is arranged above the material dividing mechanism, and includes positioning side plates 6 on both sides, an upper pressure rod 8 whose end is positioned in the adjustment groove 7 of the positioning side plate 6, and a pressure roller 9 rollingly sleeved on the upper pressure rod 8. The first conveying mechanism and the second conveying mechanism are respectively arranged obliquely above and below the upper pressure rod 8.

[0037] Multiple first conveyor belts 3 are provided, spaced axially along the first drive roller 2 and axially limited. This design allows for manual sorting of defective circuit boards 13 by placing a hand in the gaps between the first conveyor belts 3 to grab the circuit boards 13, thus preventing injury to the hand from being caught by the circuit boards 13 while the conveyor belt is in operation.

[0038] The swing plate 5 is a hollow structure composed of a connecting shaft and several side plates extending from the side of the connecting shaft. The side plates are connected to the rotating shaft 4 to reduce the friction resistance between the swing plate 5 and the front end of the circuit board 13 when the swing plate 5 rotates, thereby improving the stability and efficiency of the friction drive of the conveying plate.

[0039] The upper pressure rod 8 is an elastic rod, so that when the swing plate 5 receives the circuit board 13, it can undergo appropriate elastic deformation to cooperate with the pressure roller 9 to press the surface of the circuit board 13, thereby avoiding the circuit board 13 from shaking when it leaves the conveying mechanism due to the failure of the conveying mechanism and the material distribution mechanism to be connected, thereby reducing its kinetic energy and lowering the conveying efficiency.

[0040] A threaded structure is provided at the end of the upper pressure rod 8, and the threaded structure is positioned on the positioning side plate 6 through a nut to facilitate the sliding, position adjustment and re-positioning of the upper pressure rod 8 in the adjustment groove 7 to carry out unloading and conveying of circuit boards of different sizes.

[0041] The working principle of a circuit board sorting and unloading conveyor line of this embodiment includes: taking the first conveying mechanism below the upper pressure rod 8 and the second conveying mechanism above it as an example, when in use, the first conveying mechanism conveys the circuit board 13 that has been inspected to its end, and the unqualified circuit board 13 is taken out by manual grabbing, or the swing plate 5 is not rotated and lifted, so that the unqualified circuit board 13 moves along the material separation mechanism to the unqualified product collection box below the second conveying mechanism for collection; for the circuit board 13 of qualified quality, the rotating shaft 4 is driven to rotate, so that the outer side of the swing plate 5 is lifted, such as Figure 3 As shown; the front end of the circuit board 13 abuts against the top surface of the swing plate 5, and through its rear end is continuously conveyed by the first conveyor belt 3, the circuit board 13 slides upward along the swing plate 5, as shown in FIG. Figure 4 As shown; when the rear end of the circuit board 13 is about to leave the first conveying mechanism, its top surface abuts against the pressure roller 9, and the upper pressure rod 8 is forced to arch upward and deform to form a downward pressure on the circuit board 13 to prevent the circuit board 13 from shaking excessively when leaving the first conveying mechanism, thereby affecting subsequent conveying, such as Figure 5 As shown; the rear end of the circuit board 13 is separated from the first conveying mechanism and continues to move upward through its initial kinetic energy, its front end docking the second conveying mechanism, and driven by the friction of the second conveyor belt 12, continues to move upward, as shown Figure 6 When the center of gravity of the circuit board 13 is within the range of the second conveying mechanism, based on the principle of leverage, the rear end of the circuit board 13 is tilted and the rotational kinetic energy is reduced and buffered by the secondary abutment roller 9, as shown; Figure 7 Finally, the second conveying mechanism conveys the qualified circuit boards 13 to the qualified product collection area for unified collection.

[0042] In summary, due to the adoption of the above technical solution, a circuit board sorting and unloading conveyor line of this embodiment has the following beneficial effects compared with the prior art:

[0043] The utility model realizes the automatic separation of qualified and unqualified circuit boards by cooperating with the dividing mechanism and the guiding mechanism of the two conveying mechanisms. The upper pressure rod and the pressure roller cooperate to guide the circuit boards when they leave the first conveying mechanism and connect to the second conveying mechanism, thereby preventing them from shaking and colliding with the device, thereby ensuring their quality. The upper pressure rod can be adjusted in height to adapt it to the sorting, unloading and conveying requirements of circuit boards of different sizes. When manual sorting is required, the first conveyor belt arranged in sections and intervals can prevent the running conveyor belt from damaging the hands of humans when manually grabbing the circuit boards, thereby achieving safe production.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
