The bottom plate 21, the fixed plate 22, the movable plate 23 and the limit plate 24 form a bracket with upper and lower hollows, which is convenient for the front and back testing of the PCBA board during the conveying process; by setting the movable plate 23 to be slidably connected to the bottom plate 21, the distance between the fixed plate 22 and the movable plate 23 can be adjusted, which can adapt to the conveying of products 60 of different sizes.

[0030] In the embodiment of the present application, the conveying mechanism is provided with two groups, one group of the conveying mechanism is installed on the two fixed plates 22, and the other group of the conveying mechanism is installed on the two movable plates 23; such an arrangement enables the two conveying mechanisms to convey the product 60 along the length direction of the limiting plate 24.

[0031] The conveying mechanism includes a first motor 41, a conveyor belt 42, an active roller shaft 43 and multiple driven roller shafts 44.

The tensioning parts at both ends are tensioned by the active roller shaft 43 and the multiple driven roller shafts 44. The conveying part is located at the bottom of the inner wall of the limit plate 24 and forms a conveying space between the limit plate 24.

[0032] Specifically, the first motor 41 is arranged on the outside of one of the fixed plates 22, the active roller 43 and several of the driven rollers 44 are arranged on the inside of the fixed plate 22, the first motor 41 drives the active roller 43 to rotate, one end of the conveyor belt 42 is sequentially sleeved on the active roller 43 and several adjacent driven rollers 44; the remaining several driven rollers 44 are arranged on the inside of the other fixed plate 22, the other end of the conveyor belt 42 is sequentially sleeved on the corresponding driven rollers 44, and the fixed plate 22 is also provided with a strip hole, one of the driven rollers 44 is inserted into the strip hole, and the tension of the conveyor belt 42 can be adjusted by moving the position of the driven roller 44 in the strip hole. The conveyor belt 42 is formed into a complete closed-loop conveyor chain by the active rollers 43 and the driven rollers 44 arranged on the two fixed plates 22, and the conveying part of the conveyor belt 42 and the inner bottom of the limiting plate 24 form a conveying space for limiting the product 60, so that the PCBA board can be conveyed along the conveying space.

[0033] In the embodiment of the present application, the blocking mechanism is provided with two groups, and the two groups of the blocking mechanisms are respectively arranged on the top of the two limit plates 24. The blocking mechanism includes a rotating cylinder 11 and a baffle 12. The rotating cylinder 11 is fixed to the top of the bracket. The output end of the rotating cylinder 11 is connected to the baffle 12 through a connecting block 13. One end of the connecting block 13 is connected to the output end of the rotating cylinder 11, and the other end of the connecting block 13 is connected to the baffle 12. Before the blocking, the connecting block 13 is in a vertical state, and the baffle 12 is located at the top of the connecting block 13. In this way, when the product 60 is tested, or when no test is required, the baffle 12 is located at a high position of the product 60, which will not affect the transportation of the product 60. When the blocking is stopped, the rotating cylinder 11 drives the connecting block 13 to rotate, and the connecting block 13 drives the baffle 12 to rotate downward to stop the product 60. The structure is simple and the operation is convenient and quick.

[0034] As an example, a first photoelectric sensor 31, a second photoelectric sensor 32, a third photoelectric sensor 33 and a fourth photoelectric sensor 34 are arranged at intervals on the top of one of the limit plates 24 along the conveying direction, wherein the first photoelectric sensor 31 and the fourth photoelectric sensor 34 are respectively located at the two ends of the limit plate 24, and the second photoelectric sensor 32 and the third photoelectric sensor 33 are close to the stop mechanism. The first photoelectric sensor 31 is used to transmit a signal when detecting that the product 60 enters the device, the second photoelectric sensor 32 is used to transmit a signal when detecting that the product 60 exits the device, the third photoelectric sensor 33 is used to transmit a signal when detecting that the product 60 is about to approach the stop mechanism, at which time the conveying mechanism can be controlled to slow down, and the fourth photoelectric sensor 34 is used to transmit a signal when detecting that the product 60 is about to approach the stop mechanism, at which time the stop mechanism is driven to operate, and the baffle 12 is driven to rotate downward to stop. By providing the above-mentioned multiple photoelectric sensors, the intelligence and stop efficiency of the stop device can be improved.

[0035] In the embodiment of the present application, a sliding drive mechanism is also included, and the sliding drive mechanism is arranged on one of the bottom plates 21 and the corresponding fixed plate 22 and movable plate 23.

[0036] As an example, the sliding drive mechanism includes a second motor 51 and a screw rod 52. The second motor 51 is installed on the bottom plate 21, and can be fixed by some mounting plates installed on the bottom plate 21 to adjust it to a suitable height position; one end of the screw rod 52 is drivingly connected to the output shaft of the second motor 51, and the other end of the screw rod 52 is rotatably connected to the fixed plate 22; the screw rod 52 is threadedly connected with a first slider 53, and the first slider 53 is connected to the moving plate 23. Specifically, the screw rod 52 passes through the moving plate 23, and the first slider 53 is located at the penetration position and fixedly connected to the moving plate 23. The second motor 51 drives the screw rod 52 to rotate, thereby driving the first slider 53 to move on the screw rod 52, thereby driving the moving plate 23 to move, and then adjusting the distance between the moving plate 23 and the fixed plate 22.

[0037] As an example, the bottom plate 21 is provided with a slide rail 211 perpendicular to the conveying direction, and the movable plate 23 is slidably connected to the slide rail 211 through a second slider 212. By arranging the slide rail 211 on the bottom plate 21, the movable plate 23 moves on the slide rail 211 through the second slider 212, which assists the movable plate 23 to move and reduces friction.
