Description

Technical Field

[0001] The present invention relates to the technical field of component plug-in, and in particular to an electronic component plug-in device. Background Art

[0002] The electronic component insertion (THT) is a traditional electronic assembly technology that uses an insertion machine to insert the pins of components into the through holes (pin holes) on the printed circuit board (PCB), and then fix them by welding to achieve electrical connection and mechanical fixation.

[0003] The existing plug-in machine plug-in process first loads the circuit board, then the plug-in machine takes the components clamped by the transmission mechanism, and inserts the removed components into the corresponding through holes of the circuit board, and then uses the pin cutting machine under the circuit board to cut off the excess pins after insertion. However, the following technical problems will arise in this process: 1. The plug-in machine presses the components into the through holes of the circuit board during plug-in, and the components and the plug-in structure of the plug-in machine will constantly contact the top of the circuit board, and the impact caused by the contact will cause certain damage to the circuit board; 2. During transportation and when the plug-in structure clamps the components, the components will be slightly tilted due to some reasons, so that the insertion of the components will fail; 3. During the sorting and transmission process, the component pins will be slightly bent due to some reasons, and the slight bending will also cause the component insertion failure; 4.

[0033] A controller is fixed on one side of the workbench 1 , the controller is electrically connected to the motor 61 , and an insertion machine is externally connected to the controller.

[0034] Working principle: The device is docked with the plug-in machine, and the plug-in machine inserts the corresponding electronic component from the top of the plug-in board 23 into the plug-in correction port 24. The component head is sleeved inside the plug-in correction port 24 and is wrapped and limited by the rubber pad 25. Because the shape of the plug-in correction port 24 is the same as the shape of the component head, the plug-in correction port 24 will slightly correct the component head when the component head is inserted into the plug-in correction port 24, so as to solve the problem that the component pins and pin holes do not match due to the tilt of the component when the plug-in machine is loading. In addition, when inserting, the component pins will be inserted into the plug-in tube 317 from the top. When the pins are tilted, the pins will contact the slope of the plug-in tube 317, and then they will be inserted into the pin holes 316 as they are pressed down. This process can solve two problems. One is that it can further solve the problem of tilting the component when the plug-in machine is loading, and the other is that it can correct the bending caused by the external force of the pins to make the pins vertical. In addition, it is also convenient for the component pins to be inserted into the pin holes 316. After the insertion of the components of one of the plug-in boards 23 is completed, the motor 61 corresponding to the plug-in correction mechanism 3 below the plug-in board 23 and the plug-in pressing and transferring mechanism 4 above the plug-in board 23 is started, and the controller starts the motor 61 to drive the gear 62 to rotate forward. The forward rotation of the gear 62 is consistent with the direction of rotation of the reciprocating screw 32 driven by the one-way gear 33. The reciprocating screw 32 rotates through the pulley 1 312, the belt 44 and the pulley 2 43 to drive the reciprocating screw 2 42 to rotate synchronously. The reciprocating screw 1 32 drives the U-shaped moving plate 1 35 to move. During the process of the U-shaped moving plate 1 35 moving from one side to the other side in the slide groove 1 37, the slide groove plate 1 36 remains stationary due to the suction of the magnet 2 39 and the fixing frame 310. After the U-shaped moving plate 1 35 moves from one side to the other side in the slide groove 1 37, the U-shaped moving plate 1 35 and the magnet 1 318 When the two cylinders 314 are sucked together, the U-shaped moving plate 35 gradually moves away from the cylinder 2 311, and the spring 1 in the cylinder 2 311 will push the piston rod of the cylinder 2 311 to extend after there is no pressure from the U-shaped moving plate 35. When extending, the cylinder 2 311 draws the gas in the two cylinders 1 314 into the cylinder 1, and then the piston rod in the cylinder 1 314 drives the correction plate 315 to move downward. After the cylinder 2 311 is fully extended, the correction plate 315 moves downward to the specified position. After the correction plate 315 and the insert tube 317 move downward and away from the pins, the U-shaped moving plate 35 drives the slide plate 36, the cylinder mounting frame 1 313 and the correction plate 315 to move out from the bottom of the mounting frame 22 along the reciprocating screw 1 32. The purpose of moving away is to facilitate the component pin cutting processing by the insertion machine after the component is transferred to the circuit board 56. At the same time, the reciprocating screw rod 242 rotates to make the L-shaped plate 47 drive the U-shaped moving plate 248 to move, and the U-shaped moving plate 248 drives the magnet 412 attracted thereto to move, and the magnet 412 drives the slide plate 2410, the cylinder mounting frame 2416, the cylinder 3 417, the fixing plate 418 and the pushing block 419 to move to the top of the plug-in board 23 after the plug-in is completed. Because the mounting block 2413 and the magnet 3 414 are blocked by the iron plate 415, the slide plate 2410 stops moving, and the L-shaped plate 47 continues to drive the U-shaped moving plate 248 to move in the slide groove 2411, so that the U-shaped moving plate 248 and the magnet 412 are moved to the top of the plug-in board 23 after the plug-in is completed. After the adsorption is released, the L-shaped plate 47 continues to move and contacts one end of the piston rod of the cylinder 46, and squeezes one end of the piston rod to shrink the internal spring 2, while the internal gas enters the interior of the cylinder 3 417 and pushes the piston rod, the fixing plate 418 and the push block 419 downward. The position of the push block 419 corresponds to the position of the plug-in correction port 24, so when moving downward, the push block 419 moves downward and contacts the component directly below. At this time, the operation of the motor 61 is stopped, so that the motor 61 drives the gear 62 to reverse, so that the gear 62 satisfies the direction of the one-way gear 2 52 to drive the reciprocating screw 3 51 to rotate, so the reciprocating screw 3 51 is rotated. 1 is rotated to make the trapezoidal moving plate 53 push the installation frame 2 55 and the circuit board 56 to move to the right below the plug-in board 23, so that the component pins correspond to the pin holes of the circuit board 56. At this time, the trapezoidal moving plate 53 is located at the thread tail of the reciprocating screw 3 51, and then the motor 61 is restarted to drive the gear 62 to rotate forward, so that the push block 419 continues to move downward, and the components are pushed downward so that all the components are inserted into the inside of the circuit board 56 at one time. The push block 419 is made of rubber material to meet the insertion of components with different heights, and then the motor 61 is restarted to drive the gear 62 to reverse, so that the trapezoidal moving plate 53 moved to the thread tail drives the installation frame 2 55 and The circuit board 56 with the plug-in installed is reset. After insertion, the L-shaped plate 47 moves to the thread tail of the reciprocating screw rod 2 42 and returns to its original position, and then drives the U-shaped moving plate 2 48 to slide to the other side in the slide groove 2 411 and attract the magnet 4 412. During this process, the spring 2 pushes the cylinder 4 46 to reset, so that the cylinder 3 417 drives the fixed plate 418 and the push block 419 to move upward. After moving upward, the L-shaped plate 47 is reset and the top of the plug-in board 23 is moved away, which is convenient for the subsequent plug-in operation of the plug-in machine. At the same time, the correction plate 315 of the plug-in correction mechanism 3 is also moved back to the bottom of the plug-in board 23, waiting for the next plug-in operation. When transferring components to the circuit board 56, the plug-in machine inserts components above other plug-in boards 23. The insertion and transfer are operated simultaneously, so the plug-in machine is in a state of continuous operation, thus avoiding the phenomenon of the plug-in machine stopping and waiting due to the replacement of the circuit board 56, and improving the plug-in efficiency. The plug-in machine and the circuit board 56 are plug-in-zero-contact through the indirect plug-in mechanism 2, the plug-in correction mechanism 3, the plug-in pressing and transferring mechanism 4 and the circuit board feeding mechanism 5, and the impact of the plug-in machine directly inserting the components on the circuit board 56 is reduced, and the circuit board 56 is protected. In the process of insertion, the errors caused by the plug-in machine clamping the components are corrected multiple times, and the bent pins of the components are repaired to avoid the situation where the components and the circuit board 56 cannot be inserted due to errors when the pins are inserted into the circuit board 56. This indirect component insertion method improves the insertion accuracy of the components, and can also reduce the opening size of the pin holes of the circuit board 56, saving costs.
