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.

[0023] See also Figure 1-4The utility model provides a technical solution: a PCB board conveying device, comprising a conveyor belt 1, a moving mechanism 2 is arranged on both sides of the conveyor belt 1, and a collecting box 3 is arranged at the bottom of one end of the conveyor belt 1.

[0024] The moving mechanism 2 includes a fixed rod 201, a transverse threaded rod 202 is arranged on the top of the fixed rod 201, a baffle 203 is arranged above the transverse threaded rod 202, and the number of the baffles 203 is two, and rollers 204 are arranged at the adjacent ends of the two baffles 203, and a groove 209 is arranged inside each baffle 203, and a round rod 205 is arranged inside the groove 209, and the round rod 205 penetrates the roller 204 and is movably connected with the roller 204, vertical rods 206 are arranged on the top and bottom of the conveyor belt 1, and a straight plate 207 is arranged at the end of the vertical rod 206 away from the conveyor belt 1, and a moving rod 208 is arranged on the top of the fixed rod 201, and the number of the moving rods 208 is two, and the bottom surfaces of the two moving rods 208 are in contact with the inner wall of the fixed rod 201, the cross-sectional shape of the fixed rod 201 is U-shaped, and the conveyor belt 1 is located between the two ends of the fixed rod 201.

[0025] A push plate 210 is arranged inside the groove 209, and the push plate 210 contacts the roller 204, and a connecting spring 211 is arranged on the side of the push plate 210 away from the roller 204. The thread on the surface of the transverse threaded rod 202 is arranged in two sections, and the two sections of the thread are arranged in opposite directions. The transverse threaded rod 202 is threadedly connected to the movement rod 208.

[0026] A cross bar 212 is disposed on one side of each movement rod 208 away from the straight plate 207 , and the cross bar 212 passes through the fixed rod 201 and is movably connected to the fixed rod 201 . A connecting rod 213 is disposed on one end of the cross bar 212 away from the movement rod 208 .

[0027] The cross-section of the connecting rod 213 is T-shaped. A support rod 214 is disposed on one side of the top end of the connecting rod 213 . One end of the support rod 214 is movably connected to the fixing rod 201 , and the support rod 214 is fixedly connected to the bottom end of the baffle 203 .

[0028] During operation, the horizontal threaded rod 202 is rotated according to the size of the PCB board. Since the thread on the surface of the horizontal threaded rod 202 is arranged in two sections, and the two sections of thread are arranged in opposite directions, the horizontal threaded rod 202 is threadedly connected with the moving rod 208. The moving rod 208 is moved by the rotation of the horizontal threaded rod 202, so that the distance between the two moving rods 208 is reduced. The moving rod 208 is movably connected to the inner wall of the fixed rod 201, which ensures the movement of the moving rod 208.

When the support rod 214 moves, the baffle 203 is pushed to move, so that the distance between the two baffles 203 is reduced, so that the roller 204 is subsequently in contact with the PCB board, and the roller 204 is moved. 204 is located on both sides of the PCB board to prevent the PCB from being offset during the transportation process and improve stability. When the roller 204 contacts the PCB, the roller 204 will move and the round rod 205 will move at the same time. Since the round rod 205 is movably connected to the baffle 203, the movement of the round rod 205 is guaranteed, and the movement of the roller 204 pushes the push plate 210 to move, squeeze the connecting spring 211 at the push plate 210, and deform the connecting spring 211 to change the position of the roller 204, so as to prevent excessive squeezing of the PCB board and reduce damage. Through the use of the conveyor belt 1, the vertical rod 206 and the straight plate 207 can be moved at the same time. When the PCB board is placed on the conveyor belt 1, the vertical rod 206 will contact the PCB board, and the PCB board will be pushed to move by the vertical rod 206 to prevent the PCB board from being stuck. When the PCB board contacts the roller 204, the sliding friction is converted into rolling friction, so as to reduce the friction on the PCB board and reduce damage.
