Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to a pin mounting device and method for the secondary frame of an automotive pen-type ignition coil. Background Technology

[0002] Pencil ignition coils combine the spark plug and ignition coil into one unit, reducing energy loss, improving combustion, and increasing fuel efficiency. Each cylinder has its own ignition coil, mounted directly on top of the spark plug, eliminating the need for high-voltage wires. This ignition method achieves precise ignition through a camshaft sensor or by monitoring cylinder compression. It is suitable for engines with any number of cylinders, but is particularly well-suited for engines with four valves per cylinder.

[0003] In automotive pen-type ignition coils, the secondary frame is a crucial supporting structure. During assembly, positive and negative high-voltage pins need to be installed on the positive and negative terminals of the secondary frame, respectively. Currently, the installation of these pins is generally done manually using connectors. However, due to the small size of the pins, manual handling is inconvenient, leading to slow assembly speed and low efficiency. To address these issues, we have developed a pin installation device and method for automotive pen-type ignition coil secondary frame to solve the existing problems. Summary of the Invention

A stepper driver 300 is provided at the end of both the left mounting platform 112 and the right mounting platform 113 near the L-shaped bracket 110. The actuator 300 is used to transport the pins. The left mounting platform 112 and the right mounting platform 113 are both provided with a punching cutter 400. The punching cutter 400 is used to punch the pins to obtain independent pins. During operation, the positive high voltage pin roll holder 111 and the negative high voltage pin roll holder 109 can respectively hold the negative high voltage pin and the positive high voltage pin roll. Then, the connecting belt is transported step by step by the connecting belt stepping driver 300.

The other side of the mounting plate 501 is also provided with a pin assembly for inserting the negative high-voltage pin into the secondary skeleton. During operation, the first cylinder 507 pushes the first transverse slide 508 to move towards the stamping cutter 400, causing the second pneumatic gripper 505 to move. Inserted into the feeding port of the stamping cutter 400, the second pneumatic gripper 505 clamps the independent negative high-voltage pin. Then, the first cylinder 507 drives the first transverse slide 508 to reset. After resetting, the second cylinder 509 drives the first lifting slide 506 and the second pneumatic gripper 505 to move downward, placing the negative high-voltage pin into the negative high-voltage pin placement seat 503. After placement, the first rodless cylinder 514 drives the conveying slide 504 to move to the other side of the mounting plate 501. Then, the negative high-voltage pin is inserted into the negative end of the secondary frame through the pin assembly.

A third pneumatic gripper 512 is installed at the lower end of the second lifting slide block 511. 11 is slidably connected to the guide rail provided at the lower end of the second transverse slide block 518; when inserting the pin, the fourth cylinder 516 drives the second transverse slide block 518 to move above the negative high voltage pin placement seat 503, and then the third cylinder 510 pushes the third pneumatic gripper 512 to move downward. The third pneumatic gripper 512 moves downward to clamp the negative high voltage pin in the negative high voltage pin placement seat 503, and then the third cylinder 510 resets. At the same time, the fourth cylinder 516 pushes the second transverse slide block 518 to the position above the left positioning post 104, and then the third cylinder 510 moves downward to insert the negative high voltage pin into the negative end of the secondary frame.

[0031] One end of the right mounting platform 113 is provided with a positive high-voltage pin insertion mechanism 700 for inserting a positive high-voltage pin into the positive terminal of the secondary frame on the right positioning post 105; the positive high-voltage pin insertion mechanism 700 includes a support back plate 701, which is fixedly connected to the upper surface of the chassis 101 near the right mounting platform 113.

A sixth cylinder 708 is installed on the bottom slide block 707. A plug-in strip 710 is installed at the output end of the sixth cylinder 708. One end of the plug-in strip 710 has a positive high voltage pin plug hole 709. The housing 101 is also provided with a mechanism for driving the bottom slide block 707 to move along the sixth slide rail 706. The second rodless cylinder 705 is activated. Above the right positioning post 105, there is also a pressing assembly for pressing the top of the secondary frame.

An eighth cylinder 715 is fixedly connected to the end of the connecting arm 716, and a pressure head 717 is installed at the output end of the eighth cylinder 715. When inserting the positive high voltage pin, the fifth cylinder 702 pushes the fourth transverse slide 703 to move towards the punch cutter 400, so that the second pneumatic rotating gripper 711 is inserted into the feeding port of the punch cutter 400 to clamp the independent positive high voltage pin. Then the fifth cylinder 702... The fourth transverse slide block 703 is reset. After reset, the second pneumatic rotary gripper 711 rotates 90 degrees. Then, the seventh cylinder 714 drives the second pneumatic rotary gripper 711 to move downward to insert the positive high voltage pin into the positive high voltage pin insertion hole 709. After insertion, the second rodless cylinder 705 drives the insertion strip 710 to move towards the right positioning post 105. After reaching the insertion position, the output end of the sixth cylinder 708 moves the insertion strip 710 upward to insert the positive high voltage pin into the positive end of the secondary frame. At the same time as insertion, the eighth cylinder 715 pushes the pressure head 717 downward to press against the top of the secondary frame to prevent the secondary frame from dislodging from the right positioning post 105, thus completing the insertion of the positive high voltage pin.

[0032] The chassis 101 is also equipped with a transfer robot 600 for transferring the secondary skeleton on the left positioning column 104 to the right positioning column 105.

Then, the second lifting module 603 moves the first pneumatic rotary gripper 606 down, so that the first pneumatic rotary gripper 606 grips the secondary frame on the material picking station. After picking up the material, the second lifting module 603 moves the first pneumatic rotary gripper 606 up. At the same time, the gripper of the first pneumatic rotary gripper 606 rotates the secondary frame to the required angle. Then, the lifting plate 604 moves the first pneumatic rotary gripper 606 to the material unloading station of the right turntable 106. Then, the second lifting module 603 moves the first pneumatic rotary gripper 606 down to insert the secondary frame into the right positioning post 105, completing the transfer of the secondary frame.

[0033] The chassis 101 is also equipped with a unloading robot 200 for unloading the processed secondary skeleton. The unloading robot 200 includes a support arm 201, which is fixedly connected to the upper surface of the chassis 101 near the right turntable 106.

The machine cover 107 is also equipped with... A guide cover 114 is provided to guide the pin assembly. After the secondary skeleton pin assembly is completed, the first lifting module 202 drives the 90-degree tilting cylinder 204 to descend, causing the first pneumatic gripper 205 to move to the unloading station of the right turntable 106. Then, the first pneumatic gripper 205 clamps the secondary skeleton, while the first lifting module 202 drives the 90-degree tilting cylinder 204 to move upward, causing the secondary skeleton to disengage from the right positioning post 105. After disengagement, the 90-degree tilting cylinder 204 actuates, causing the first pneumatic gripper 205 to tilt 90 degrees, making the first pneumatic gripper 205 horizontal. Then, the first pneumatic gripper 205 releases the secondary skeleton, and the secondary skeleton falls into the discharge chute 115 for collection.

[0034] The specific workflow of this invention is as follows: First, both the positive and negative high-voltage pins are processed as a continuous strip, coiled and ready for use; rather than separate individual components.

[0035] Left S4: Left turntable 103 continues to rotate, and the secondary frame with the negative high voltage pin installed moves to the left end position; At this point, the installation cycle for one negative high-voltage pin on the left unit is complete.

[0036] Right unit: Right S1: Positive high voltage pin with reel, unwinding - right with stepper driver 300 - right punching cutter 400 - right positive high voltage pin insertion mechanism 700 delivers a single positive high voltage pin to the right installation station; Right S2: The transfer robot 600 picks up the secondary skeleton at the left end station and places it on the right positioning post 105 of the right turntable 106 (the upper hole of the secondary skeleton is still facing upward); the right turntable 106 rotates intermittently, and the secondary skeleton on the right positioning post 105 reaches the right installation station; the pressure head 717 driven by the eighth cylinder 715 presses down on the secondary skeleton. Right S3: Right sixth cylinder 708 pushes the positive high voltage pin on the plug-in block 710 upward and installs it into the lower side hole of the secondary frame.

[0037] Right S4: The right turntable 106 continues to rotate, and the secondary frame with the positive high voltage pin installed moves to the right end position. The installation cycle for one positive high-voltage pin on the right unit has been completed.
