Description

Technical Field

[0001] The utility model relates to the technical field of board loading machines, in particular to an SMT board loading machine for PCB boards. Background Art

[0002] The SMT loader for PCB boards is a device that can be used for surface mounting of PCB boards. The SMT loader can place PCB boards on the automated production line, automatically feeding unsoldered PCB boards into the production line for placement. The SMT loader can also automatically feed PCB boards with mounted components into the reflow oven or other subsequent processing equipment, reducing manual operations and improving production efficiency. Through fast and efficient board loading, the output of the entire production line can be significantly increased, the need for manual intervention can be reduced, errors and risks caused by human operation can be reduced, and the safety of the working environment can be improved.

[0003] When the SMT loader is operating, the PCB board needs to be placed inside the material frame. The partitions of the material frame can place each PCB board at equal intervals, so that the push rod of the SMT loader can accurately push the PCB board. During the operation of the SMT loader, to ensure that the placement quality meets the standards and to detect possible defects in a timely manner, the staff usually randomly removes the PCB board for inspection regularly. When the staff places the PCB board after inspection, if it is not aligned or not placed stably, it is easy to cause subsequent patch position deviation. Therefore, we propose an SMT loader for PCB boards. Utility Model Content

The synchronous wheel 205 of the first bevel gear 207 is fixed to the first bevel gear 207, and the first bevel gear 207 is connected to the second bevel gear 208. A connecting rod 209 is fixed to one side of the second bevel gear 208. The first bevel gear 207, the second bevel gear 208 and the connecting rod 209 are movably connected to the fixed splint 1021 and the movable splint 1022 through bearings respectively. A sliding rod 210 slides through the inner side of the lower end of the connecting rod 209, and one end of the sliding rod 210 is sleeved with a connecting spring 211. The two ends of the connecting spring 211 are fixed to the connecting rod 209 and the sliding rod 210 respectively. The end of the sliding rod 210 close to the connecting spring 211 is inlaid with the first The magnetic block 212, the side of the fixed splint 1021 close to the first magnetic block 212 and the side of the movable splint 1022 close to the first magnetic block 212 are inlaid with the second magnetic block 213, the first magnetic block 212 and the second magnetic block 213 are in contact with each other, the slide 202 matches the slide groove 203, the slide 202 and the screw 204 are threadedly connected, the synchronous wheel 205 and the synchronous belt 206 are meshed and docked, the first bevel gear 207 and the second bevel gear 208 are meshed and docked, the inner side of the lower end of the connecting rod 209 matches the diameter of the slide rod 210, the first magnetic block 212 and the second magnetic block 213 are magnetically attracted, and the pressure plate 201 is composed of a support frame and a roller.

[0022] In specific implementation, according to Figure 1-Figure 4When the SMT loading machine is operating, the PCB board needs to be placed on the inner side of the material frame body 102. At this time, the position of the movable clamping plate 1022 inside the material frame body 102 is adjusted so that the distance between the material frame body 102 and the fixed clamping plate 1021 matches the PCB board. At this time, the PCB board is placed on the upper side of the partition 2, and the sliding rod 210 is pulled outward to squeeze the connecting spring 211 to make it contract. At this time, the first magnetic block 212 and the second magnetic block 213 are disengaged from the magnetic attraction, so that the staff can hold the sliding rod 210 to drive the connecting rod 209 to rotate, so that the connecting rod 209 can drive the second bevel gear 208 to rotate, and the first bevel gear 207 and the connecting spring 211 are connected. The second bevel gear 208 is meshed and docked, so that the first bevel gear 207 can rotate along with the second bevel gear 208, so that the first bevel gear 207 can drive the synchronous wheel 205 to rotate, and the synchronous wheel 205 is meshed and docked with the synchronous belt 206, so that each synchronous wheel 205 can rotate at the same time, so that the synchronous wheel 205 can drive each screw 204 to rotate at the same time, and the slide plate 202 is matched with the slide groove 203, so that the slide plate 202 is not easy to rotate along with the screw 204, and the slide plate 202 is threadedly connected to the screw 204, so that the slide plate 202 can slide stably along the slide groove 203, so that the slide plate 202 can stably drive the pressure plate 201 to rotate. When the pressing plate 201 moves downward and away from the partition 2, the roller of the pressing plate 201 can squeeze the PCB so that the PCB is restricted to the upper side of the partition 2. At this time, the sliding rod 210 is released, and the sliding rod 210 drives the first magnetic block 212 and the second magnetic block 213 to fit together under the action of the connecting spring 211.

When the operator spot-checks the PCB board, the PCB board can be directly pulled out. At this time, the roller of the pressing plate 201 rotates, reducing the friction between the pressing plate 201 and the PCB board, making it convenient for the operator to pull out the PCB board for inspection. Moreover, when the material frame body 102 is moved, the roller of the pressing plate 201 does not rotate under inertia, so that the PCB board can be stably restricted on the upper side of the partition 2 when the material frame body 102 moves. When the operator places the PCB board for inspection, the PCB board can be placed stably and neatly under the limitation of the fixed clamping plate 1021, the movable clamping plate 1022 and the pressing plate 201, so that the placement position of the PCB board after inspection is not prone to deviation, and it is not easy to cause the subsequent patch position to shift.

When the staff checks the PCB board, the PCB board is directly pulled out. At this time, the roller of the pressure plate 201 rotates, which is convenient for the staff to pull out the PCB board for inspection. When the staff places the PCB board after inspection, the PCB board can be placed stably and neatly under the limitation of the fixed clamp 1021, the movable clamp 1022 and the pressure plate 201, so that the placement position of the PCB board after inspection is not easy to deviate, and it is not easy to cause the subsequent patch position to shift.
