Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and in particular relates to an integrated machine for automatic bending and welding of circuit board leads. Background Technology

[0002] Circuit board pins refer to the metal feet or contact points on electronic components used to connect to the circuit board. Component pins are usually connected to solder holes on the circuit board by soldering to form an electrical connection, ensuring the transmission of current or signals. In the circuit board pin processing, bending and soldering of the pins are critical processes that directly affect product reliability and production efficiency. Bending and soldering machines are used for pin bending and soldering.

[0003] Existing integrated bending and welding machines typically employ a single-station bending mode, meaning that only one pin can be bent at a time, and welding can only proceed after bending is complete. Because bending and welding processes must alternate, the equipment must wait for the next pin to be bent while welding, limiting production efficiency. Furthermore, the welding fumes produced contain harmful substances, and direct emission would endanger the working environment and the health of operators. Treatment usually relies on external welding fume purification equipment, which not only occupies additional space but also increases equipment purchase and maintenance costs.

[0004] To address these issues, we provide an integrated automatic bending and soldering machine for circuit board pins. Utility Model Content

The top of cylinder 18 is fixedly connected to the rotating disk 4, and the output end of the second cylinder 18 is fixedly connected to the lower pressure plate 8. The purification mechanism also includes a filter screen 19 fixedly connected inside the purification chamber 9. The filter screen 19 is used to filter solid particles. During purification, activated carbon fills the space between the filter screen 19 and the purification chamber 9. An annular hollow plate 20 is rotatably connected to the top of the rotating disk 4. The annular hollow plate 20 is located on the surface of the output end of the motor 15. A through groove is opened on its top to ensure the normal rotation of the output end of the motor 15.

The bottom of the annular hollow plate 20 is provided with a guide groove. The rotating disk 4 is also hollow and is connected to the through pipe 21 on one side of the air collecting hood 12. The end of the through pipe 21 away from the air collecting hood 12 passes through to the side of the vertical plate 5 away from the air collecting hood 12 and communicates with the rotating disk 4. The top of the rotating disk 4 is provided with a guide hole, which communicates with the guide groove. The top of the purification box 9 is fixedly connected to a sealing plate by bolts. The bottom of the sealing plate is in close contact with the filter screen 19. The top of the sealing plate is fixedly connected to a handle. The suction fan 1 A mesh partition is fixedly connected to the air inlet end of the 0 air intake.

[0030] The working principle of this utility model is as follows: the pin is placed between the clamping plate 17 and the supporting plate 6. The bending position of the pin is adjusted by controlling the depth of one end of the pin inserted into the socket. The clamping plate 17 is driven to move down to fix the pin by the first cylinder 16, and the lower pressure plate 8 is driven by the second cylinder 18 to complete the bending action. The dual-station design allows two pins to be processed at the same time, shortening the processing cycle. After bending, the third cylinder 22 moves the pin down to the welding position, and the welding head 3 performs welding. During welding, the suction fan 10 is started, and the welding fume enters the purification box 9 through the air collection hood 12, the through pipe 21, and the guide hole, and is discharged after being purified by activated carbon and filter screen 19.

[0031] After a single pin is welded, motor 15 drives the rotating disk 4 to rotate half a turn, allowing the bent pin at another station to enter the welding position, thus enabling continuous operation. Welding fumes, after being filtered by filter 19 to intercept particulate matter and activated carbon to adsorb harmful gases within the purification chamber 9, are discharged as clean air by the exhaust fan 10. Mesh partitions and dustproof nets further ensure purification effectiveness and equipment safety. The activated carbon can be replaced periodically by opening the sealing plate. Through automated design and functional integration, the problems of low efficiency and high processing costs associated with traditional equipment are effectively solved, demonstrating significant practicality and economic benefits.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
