[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The present invention provides a technical solution: a docking platform for preventing PCB boards from falling, comprising a platform body 1, wherein two guide rails 2 are symmetrically installed on the upper surface of the platform body 1, and a motor 3 is symmetrically installed on the two guide rails 2 away from one side. The motor 3 is symmetrically installed on the output shaft of the motor 3, and a plurality of sprockets are installed on the corresponding two sprockets to engage with a chain 4. The guide rail 2 is connected to a limit plate 5 on the side near the chain 4. The limit plate 5 is provided with a fixing plate 6 on the side near the chain 4. One end of the fixing plate 6 is an inclined surface 7. A plurality of bases 8 are provided on the surface of the chain 4 near the guide rail 2. A push rod 9 is slidably connected to the surface of the base 8. The base 8 is connected to a spring 10 on the side away from the limit plate 5. The spring 10 is connected to the push rod 9. One end of the push rod 9 close to the limit plate 5 is in contact with the fixing plate 6. The guide rail 2 and the platform body 1 are connected by a screw rod. The connection method is the existing technology. The distance between the two guide rails 2 can be adjusted by rotating the screw rod with a hand crank handle to adapt to PCB boards of different widths. The operation method is the existing technology and will not be repeated here.

[0026] During operation, the motor 3 drives the sprocket and chain 4 to rotate, and the PCB board enters between the two guide rails 2. The two sides of the PCB board are placed on the upper surface of the chains 4 on both sides. The entry direction of the PCB board is consistent with the rotation direction of the chain 4. The rotation of the chain 4 drives the base 8 and the push rod 9 to move. After one end of the push rod 9 contacts the inclined surface 7, the inclined surface 7 can guide the push rod 9, so that the push rod 9 moves toward the PCB board, and then the push rods 9 on both sides clamp the middle PCB board. The chain 4 continues to drive the push rod 9 to move, so that the push rod 9 moves while clamping the PCB board. During the movement, one end of the push rod 9 will be close to the surface of the fixed plate 6.

[0027] See also Figure 1-5 The utility model provides a technical solution: a sliding groove 11 is opened on the side of the limiting plate 5 close to the chain 4, one end of the support rod 9 extends into the inside of the sliding groove 11, and the fixed plate 6 is located on one side of the inside of the sliding groove 11.

[0028] During operation, the slide groove 11 can limit and guide the push rod 9 through the setting of the slide groove 11, so that the movement process of the push rod 9 is more stable.

[0029] See also Figure 1-5The utility model provides a technical solution: a plurality of chains 4 are provided with rubber conveyor belts 12 on their surfaces, and a rubber conveyor belt 12 is not provided on the surface of the chain 4 close to the guide rail 2 .

[0030] During operation, the friction between the surface of the chain 4 and the PCB board can be increased by setting the rubber conveyor belt 12, which is beneficial to the transportation of the PCB board. The chain 4 close to the guide rail 2 does not contact the PCB board.

[0031] See also Figure 1-5 The utility model provides a technical solution: one end of the push rod 9 close to the slide groove 11 is rotatably connected to the pulley 13, and the surface of the pulley 13 is in contact with the inner wall of the slide groove 11.

[0032] During operation, when the push rod 9 moves, the pulley 13 rotates in the slide groove 11. The setting of the pulley 13 can reduce the friction between the push rod 9 and the inner wall of the slide groove 11, which is beneficial for the chain 4 to drive the push rod 9 to move.

[0033] See also Figure 1-5 The utility model provides a technical solution: the pulley 13 is connected to a shell 14 on the side close to the limit plate 5, the shell 14 is hemispherical, and the side of the shell 14 away from the pulley 13 is in contact with the inner wall of the chute 11.

[0034] During operation, the setting of the housing 14 can reduce the friction between the side of the pulley 13 and the slide groove 11, which is beneficial to the use of the pulley 13 and the movement of the lever 9.

[0035] See also Figure 1-5 The utility model provides a technical solution: the limiting plate 5 is symmetrically connected to the side of the guide rail 2 and rotated with two screws 15, which pass through the guide rail 2 and are threadedly connected to the guide rail 2.

[0036] During operation, due to the action of the spring 10, the push rod 9 is in close contact with the fixed plate 6. When the position of the limit plate 5 moves, the position of the fixed plate 6 and the push rod 9 will change. The position of the limit plate 5 can be adjusted by rotating the screw 15, thereby adjusting the distance between the limit plates 5 on both sides, and then adjusting the clamping force of the push rod 9 on the PCB board.

[0037] See also Figure 1-5 The utility model provides a technical solution: a plurality of guide rods 16 are connected to the side of the limit plate 5 close to the guide rail 2, and the guide rods 16 pass through the guide rail 2 and are slidably connected to the guide rail 2.

[0038] During operation, the guide rod 16 can limit the limit plate 5 , which is beneficial to the stability of the limit plate 5 during use.

[0039] In summary, the motor 3 drives the sprocket and chain 4 to rotate, and the PCB board enters between the two guide rails 2. The two sides of the PCB board are placed on the upper surface of the rubber conveyor belts 12 on both sides. The entry direction of the PCB board is consistent with the rotation direction of the chain 4. The rotation of the chain 4 drives the base 8 and the push rod 9 to move. After one end of the push rod 9 contacts the inclined surface 7, the inclined surface 7 can guide the push rod 9, so that the push rod 9 moves toward the PCB board, and then the push rods 9 on both sides clamp the middle PCB board. The chain 4 continues to drive the push rod 9 to move, so that the push rod 9 moves while clamping the PCB board. During the movement, one end of the push rod 9 will be close to the surface of the fixed plate 6. The position of the limit plate 5 can be adjusted by rotating the screw 15, thereby adjusting the distance between the limit plates 5 on both sides, and then adjusting the clamping force of the push rod 9 on the PCB board.
