Description

Technical Field

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

[0002] Through-hole technology (THT) for electronic components is a traditional electronic assembly technology. Components' pins are inserted into the through-holes (pin holes) on a printed circuit board (PCB) by a plug-in machine, and then fixed through soldering to achieve electrical connection and mechanical fixation.

[0003] The process of the existing plug-in machine for plugging components is as follows: First, the circuit board is loaded. Then, the plug-in machine picks up the components clamped by the transfer mechanism and inserts the picked-up components into the corresponding through-holes of the circuit board. After insertion, the redundant pins are cut off by a pin cutting machine under the circuit board. However, the following technical problems will occur in this process: 1. When the plug-in machine plugs the components, it presses the components into the through-holes of the circuit board, and both the components and the plug-in structure of the plug-in machine will continuously 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, resulting in insertion failure when the components are inserted; 3. During the sorting and transfer of the components, the pins of the components will be slightly bent due to some reasons, and the slight bending will also cause insertion failure of the components; 4. When replacing the circuit board, the plug-in machine needs to stop and wait, and the stop and wait will affect the insertion efficiency of the components. Summary of the Invention

[0049] A controller is fixed on one side of the workbench 1. The controller is electrically connected to the motor 61. The controller is externally connected to a plug-in machine.

[0050] Working principle:

[0051] This device is docked with the plug-in machine. The plug-in machine inserts the corresponding electronic components into the interior of the plug-in calibration port 24 from the top of the plug-in board 23. The component head is sleeved inside the plug-in calibration port 24 and is wrapped and limited by the rubber pad 25. Since the shape of the plug-in calibration port 24 is the same as that of the component head, when the component head is inserted into the interior of the plug-in calibration port 24, the plug-in calibration port 24 will slightly correct the component head, solving the situation where the pins of the component are misaligned with the pin holes due to the inclination of the component during the feeding of the plug-in machine. Additionally, when inserting, the pins of the component will be inserted into the insertion cylinder 317 from the top. When the pins are inclined, the pins will contact the slope of the insertion cylinder 317, and then will be inserted into the interior of the pin hole 316 as the pressure is applied downward. This process can solve two problems. One is that it can further solve the inclination of the components during the feeding of the plug-in machine. The other is that it can correct the bending of the pins caused by external forces, making the pins vertical. Additionally, it also facilitates the insertion of the pins of the component into the interior of the pin hole 316.

[0052] After the components on one plug-in board 23 are inserted, the motor 61 corresponding to the plug-in calibration mechanism 3 below the plug-in board 23 and the plug-in pressing and transferring mechanism 4 above is started. The controller starts the motor 61 to drive the gear 62 to rotate forward. The forward rotation of the gear 62 conforms to the rotation direction of the one-way gear one 33 to drive the reciprocating screw one 32 to rotate. The reciprocating screw one 32 rotates to drive the reciprocating screw two 42 to rotate synchronously through the pulley one 312, the belt 44, and the pulley two 43. The reciprocating screw one 32 drives the U-shaped moving plate one 35 to move. During the process of the U-shaped moving plate one 35 moving from one side to the other side in the chute one 37, the chute plate one 36 remains stationary due to the suction force of the magnet two 39 and the fixed frame 310. After the U-shaped moving plate one 35 moves from one side to the other side in the chute one 37, the U-shaped moving plate one 35 is attracted to the magnet one 318. When the U-shaped moving plate one 35 moves, the U-shaped moving plate one 35 gradually moves away from the cylinder two 311, and the spring one in the cylinder two 311 will push the piston rod of the cylinder two 311 to extend after there is no pressure from the U-shaped moving plate one 35. When extending, the cylinder two 311 pumps the gas in the two cylinders one 314 into it, and then the piston rod in the cylinder one 314 drives the calibration plate 315 to move downward. After the cylinder two 311 is fully extended, the calibration plate 315 moves downward to the specified position. After the calibration plate 315 and the insertion cylinder 317 move downward and away from the pins, the U-shaped moving plate one 35 drives the chute plate one 36, the cylinder mounting frame one 313, and the calibration plate 315 to move out of the lower part of the mounting frame one 22 along the reciprocating screw one 32. The purpose of moving away is to facilitate the plug-in machine to cut off the pins of the components after the components are transferred to the circuit board 56.

[0053] Meanwhile, the reciprocating screw two 42 rotates to drive the L-shaped plate 47 to drive the U-shaped moving plate two 48 to move. The U-shaped moving plate two 48 drives the magnet four 412 attracted to it to move. The magnet four 412 drives the chute plate two 410, the cylinder mounting bracket two 416, the cylinder three 417, the fixing plate 418, and the push block 419 to move directly above the plug-in board 23 that has completed plugging. Since the mounting block two 413 and the magnet three 414 are blocked by the iron plate 415, the chute plate two 410 stops moving. The L-shaped plate 47 continues to drive the U-shaped moving plate two 48 to move within the chute two 411, causing the U-shaped moving plate two 48 to release the adsorption with the magnet four 412. When the L-shaped plate 47 continues to move, it will contact one end of the piston rod of the cylinder four 46 and squeeze one end of the piston rod to contract the spring two inside. And the gas inside enters the inside of the cylinder three 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 to contact the component directly below. At this time, the operation of the motor 61 is stopped, and the motor 61 is driven to reverse the gear 62, so that the gear 62 meets the rotation direction of the reciprocating screw three 51 driven by the one-way gear two 52. Therefore, the reciprocating screw three 51 rotates to drive the trapezoidal moving plate 53 to push the mounting frame two 55 and the circuit board 56 to move directly below the plug-in board 23, making 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 end of the reciprocating screw three 51. Then the motor 61 is restarted to drive the gear 62 to rotate forward, causing the push block 419 to continue to move downward, pushing the component downward to insert all the components 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. Then the motor 61 is restarted to drive the gear 62 to reverse, causing the trapezoidal moving plate 53 that has moved to the thread end to drive the mounting frame two 55 and the circuit board 56 with plugs to reset. After insertion, the L-shaped plate 47 moves to the thread end of the reciprocating screw two 42 and returns, then drives the U-shaped moving plate two 48 to slide to the other side within the chute two 411 and adsorb with the magnet four 412. During this process, the spring two pushes the cylinder four 46 to reset, causing the cylinder three 417 to drive the fixing plate 418 and the push block 419 to move upward. After moving upward, it follows the L-shaped plate 47 to reset, moving away from above the plug-in board 23, facilitating the plugging operation of the subsequent plug-in machine. At the same time, the correction plate 315 of the plug-in correction mechanism 3 also moves back directly below the plug-in board 23, waiting for the next plugging operation;

[0054] When transferring components to the circuit board 56, the component insertion machine performs component insertion above other insertion boards 23, and the insertion and transfer operations are carried out simultaneously. Therefore, the component insertion machine is in a continuous working state, avoiding the phenomenon that the component insertion machine stops working and waits due to the replacement of the circuit board 56, improving the insertion efficiency. Through the indirect insertion mechanism 2, the insertion calibration mechanism 3, the insertion pressing and transfer mechanism 4, and the circuit board loading mechanism 5, zero-contact insertion between the component insertion machine and the circuit board 56 is achieved, reducing the impact on the circuit board 56 caused by the direct insertion of the component insertion machine on the circuit board 56, protecting the circuit board 56. And during the insertion process, the errors caused by the component insertion machine clamping the components are calibrated multiple times, and the bent pins of the components are repaired, avoiding the situation where the components and the circuit board 56 are damaged 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 on the circuit board 56, saving costs.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
