Description

Technical Field

[0001] This invention relates to the field of cleaning technology for I-shaped FPCs, and in particular to a cleaning method and equipment for FPC solder joints. Background Technology

[0002] Currently, FPC solder joints need to be cleaned because the solder materials used in the soldering process contain activators. These activators can improve wettability and spreadability during soldering, but there will be residues after soldering, which may corrode the substrate.

[0003] The production process of FPC boards is relatively complex. After processes such as reflow soldering and adhesive spraying, the surface of the solder joints needs to be cleaned with a gold surface cleaner to remove residual flux, activators and other dirt. Traditional cleaning methods are prone to leaving cleaning solution residue, which not only affects the quality of the FPC board, but also affects subsequent processing.

[0004] To address these issues, we developed a method and equipment for cleaning FPC welding points. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a cleaning method and equipment for FPC welding points, which has the advantages of improving positioning efficiency, improving yield, and improving cleaning efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a cleaning method and cleaning equipment for FPC solder joints. The FPC product includes a product body, with cleaning ends vertically disposed at both ends of the product body. Solder joints are disposed at both ends of the cleaning ends. The solder joint cleaning method is implemented by a cleaning equipment, which includes a first support, a second support, and a third support. A first servo module is fixedly connected to the top of the first support and the second support. A product positioning module is slidably connected to the top of the first servo module. A barcode scanning position is mounted on the top of the first support. A servo receiving module is fixedly connected to the top of the third support. A second servo module and a servo transfer module are mounted on the top of the second support. A moving plate is slidably connected to the top of the second servo module. A cleaning module is disposed on the side wall of the moving plate. A cleaning wiping structure is fixedly connected to the middle position of the cleaning module via a guide rail plate. A controller is fixedly connected to the top of the second support. The controller is electrically connected to the first servo module, the barcode scanning position, the second servo module, the servo transfer module, and the servo receiving module. The solder joint cleaning method includes the following steps: S10. Product loading and positioning: The front-end robot places the product on the top of the product positioning module. The bottom of the product positioning module is equipped with a lower transfer positioning module. The bottom of the lower transfer positioning module is slidably connected to the first servo module, and a secondary positioning module is mounted on the top. The controller controls the first and second micro cylinders of the lower transfer positioning module to push the product edge sideways and position it neatly. The bottom of the product is then adsorbed by the first vacuum suction cup. S20. Product scanning: The secondary positioning module transfers the product to the scanning position through the first servo module, and the scanning position scans the product using a barcode scanner; S30. Wiping and cleaning product: A second servo module is mounted on one end of the first servo module. The second servo module moves the cleaning module to the wiping position at the top of the product positioning module. A cleaning head is provided at the bottom of the cleaning and wiping structure. When the cleaning and wiping structure is pressed down, the cleaning head cleans the solder joints through a spray of lint-free cloth. S40. Transfer and unloading: One end of the first servo module is a transfer unloading position. The first servo module transfers the product to the transfer unloading position. The second servo module has a servo transfer module at the end away from the scanning position. The servo transfer module drives the unloading module to transfer the product to the transfer unloading position. The unloading module presses down to attract the product at the top of the product positioning module. S50. Product positioning module return: The first servo module drives the product positioning module to return to its original position. One end of the first servo module is equipped with a servo receiving module. The servo receiving module is located at the original waiting position at one end of the first servo module. The top of the servo receiving module is slidably connected to a material unloading positioning module, and the material unloading positioning module returns to the original waiting position. S60. Product unloading: The unloading module transfers the product to the unloading positioning module, and then the unloading positioning module transfers the product to the manual unloading position. The operator takes out the cleaned product, and the unloading positioning module returns to the original waiting position.
