Description

Technical Field

[0001] The utility model relates to the technical field of inkjet coding, in particular to an FPC inkjet coding device. Background Art

[0002] FPC flexible circuit board is a kind of highly reliable and flexible printed circuit board made of polyimide or polyester film as the base material. It is referred to as soft board and has the characteristics of high wiring density, light weight and thin thickness.

[0003] FPC inkjet printer uses the principle of charged ink particles deflected by high-voltage electric fields to print patterns, text and numbers on the surface of various objects. It can be used to print the production date, batch number, barcode, trademark pattern, anti-counterfeiting mark and Chinese characters of FPC flexible circuit boards. Inkjet printers are used for printing in the production process of FPC.

[0004] According to the announcement number (CN207859754U), a multi-nozzle FPC inkjet coding device is proposed, which includes a printing device, a receiving part, a receiving part transporting device, a workbench, and a workbench base. The receiving part transporting device is composed of a conveyor and a driving roller. The receiving part is arranged in a groove on the workbench that matches the size of the receiving part and is fixedly connected to the conveyor. By fixing the lighter FPC flexible circuit board in the platform groove of the receiving part, technical problems such as inaccurate coding caused by the FPC flexible circuit board during printing are reduced.

[0005] However, in actual use, due to the different sizes of FPC flexible circuit boards, the above solution can only place FPC flexible circuit boards that are just snapped into the groove. When facing FPC flexible circuit boards with smaller sizes, the FPC flexible circuit boards will still shake slightly under the unidirectional spraying force, resulting in inaccurate coding. In addition, after the printing is completed, the above solution directly puts the FPC flexible circuit board into the collection box. However, because the ink on the FPC flexible circuit board has not dried yet, the FPC flexible circuit boards that fall into the collection box will rub against each other, thereby causing the ink that has not dried to be scratched, and the scratched FPC flexible circuit board will affect subsequent use.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-4, an FPC coding device comprises a base plate 1, two fixed plates 2 are fixedly installed on the top side of the base plate 1, a conveying assembly is arranged between the two fixed plates 2, a plurality of placement blocks 8 are arranged on the outside of the conveying assembly, the placement blocks 8 are respectively provided with placement slots and long slots, the long slots are connected to the placement slots, and a clamping assembly is arranged in the long slots. A bracket 13 is fixedly installed on the top side of the two fixed plates 2, and the two brackets 13 are U-shaped. The side where the two brackets 13 are close to each other is fixedly connected to the same inkjet printer 14, and the inkjet printer 14 faces the conveying assembly, and the top side of the two fixed plates 2 is fixedly installed with the same fixed bracket 15, and a drying assembly is arranged in the fixed bracket 15. A collecting assembly is arranged on one side of the base plate 1, and a mechanical arm 23 is provided to realize automatic loading of the FPC flexible circuit board. Before the FPC flexible circuit board is stenciled, the operation of each component is controlled by the controller, so that during the loading process, coding, conveying and drying are carried out simultaneously, thereby realizing the automation of loading, coding, drying and collecting of the FPC flexible circuit board.

[0025] Specifically, the conveying assembly includes a first motor 3 fixedly installed on one side of the left fixed plate 2, the output end of the first motor 3 rotates through the fixed plate 2 and is fixedly installed and rotatably connected to one side of the other fixed plate 2, and a fixed cylinder 4 is fixedly sleeved on the outer side of the output end of the first motor 3, and the same fixed rod 5 is fixedly installed on the side where the two fixed plates 2 are close to each other, and a movable cylinder 6 is movably sleeved on the outer side of the fixed rod 5. The same conveyor belt 7 is provided on the outer sides of the movable cylinder 6 and the fixed cylinder 4, and multiple placement blocks 8 are fixedly connected to the outer side of the conveyor belt 7. When the placement blocks 8 need to be conveyed, the fixed cylinder 4 is driven to rotate by the operation of the first motor 3, so that the fixed cylinder 4 drives the outer conveyor belt 7 to move, and the movable cylinder 6 provided can support the conveyor belt 7 and also assist in movement.

[0026] Specifically, the clamping includes a threaded motor 9 fixedly installed on one side of the placement block 8, and the output end of the threaded motor 9 rotates through the placement block 8 and is fixedly installed with a bidirectional screw 10, and the other end of the bidirectional screw 10 is rotatably connected to the inner wall of one side of the long slot, and two sliders 11 are slidably installed on the outer side of the bidirectional screw 10, and one side of the two sliders 11 is fixedly installed with a clamping plate 12, and the two clamping plates 12 are both located in the placement slot opened by the placement block 8, and the two clamping plates 12 are both made of rubber. When the robotic arm 23 places the FPC flexible circuit board to be coded in the placement slot, the threaded motor 9 drives the bidirectional screw 10 to rotate clockwise, so that the two sliders 11 drive the two clamping plates 12 to move toward the two sides of the FPC flexible circuit board, thereby completing the clamping of the FPC flexible circuit board, and because the two clamping plates 12 are both rubber components, the FPC flexible circuit board can be prevented from being damaged during the clamping process, and because the distance between the two clamping plates 12 is adjusted by the threaded motor 9, FPC flexible circuit boards of different sizes can be clamped, and the adaptability is better.

[0027] Specifically, the drying component includes a heating box 17 fixedly installed on the inner wall of the fixed frame 15, and a plurality of heating rods 18 are arranged in the heating box 17. Two second motors 19 are fixedly installed on the top side of the fixed frame 15. The output ends of the two second motors 19 rotate and pass through the fixed frame 15. A plurality of fan blades 20 are fixedly installed on the outer sides of the output ends of the two second motors 19. The plurality of fan blades 20 are all facing the heating rods 18. Baffles 16 are fixedly installed on both sides of the fixed frame 15. Through the plurality of heating rods 18 and the second motor 19, the FPC flexible circuit board after the coding is completed will be moved to the bottom of the fixed frame 15 by the conveyor belt 7. At this time, the plurality of heating rods 18 and the second motor 19 are started synchronously. The operation of the second motor 19 can drive the plurality of fan blades 20 to rotate, and during the rotation process, the hot air generated by the heating rods 18 can be blown toward the FPC flexible circuit board, so that the ink on the surface of the FPC flexible circuit board can be quickly dried, so as to prevent the ink on the surface of the multiple FPC flexible circuit boards from being scratched or contaminated on other FPC flexible circuit boards when they fall into the collection box 21.

[0028] Specifically, the collection component includes a through opening on one side of the base plate 1, in which a collection box 21 is fixedly installed, and a sponge pad 22 is fixedly installed in the collection box 21. The sponge pad 22 is arranged at an angle, and a mechanical arm 23 is fixedly installed on the top side of the base plate 1. The mechanical arm 23 is located on one side of the right fixed plate 2. By setting the sponge pad 22 in the collection box 21, the FPC flexible circuit board falling from the placement block 8 can be buffered to avoid the FPC flexible circuit board falling directly into the collection box 21 and being damaged. The sponge pad 22 can reduce the occurrence of this situation.

[0029] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.

[0030] During use: the FPC flexible circuit board to be coded is placed in the placement slot opened by the placement block 8 through the mechanical arm 23, and then the threaded motor 9 is started to drive the bidirectional screw 10 to rotate clockwise, so that the two sliders 11 drive the two clamping plates 12 to clamp the FPC flexible circuit board to avoid the position deviation of the FPC flexible circuit board during the coding and transportation process, thereby causing the deviation of the subsequent coding. After the clamping is completed, the conveyor belt 7 can be used to transport the placement block 8 through the operation of the first motor 3. When the placement block 8 moves to the bottom of the inkjet printer 14, the inkjet printer 14 can run to print the code toward the clamped FPC flexible circuit board. After the coding is completed, the FPC flexible circuit board will be moved to the bottom of the fixed frame 15 by the conveyor belt 7. At this time, multiple heating rods 18 and the second motor 19 are started synchronously. The operation of the second motor 19 can drive multiple fan blades 20 to rotate, and during the rotation process, the hot air generated by the heating rod 18 can be blown to the FPC flexible circuit board, so that the F The ink on the surface of the PC flexible circuit board dries quickly, and baffles 16 are fixedly installed on both sides of the fixing frame 15. The two baffles 16 can reduce the leakage of hot air. After drying, the threaded motor 9 drives the bidirectional screw 10 to rotate counterclockwise, so that the two clamps 12 stop clamping the FPC flexible circuit board. Then the conveyor belt 7 runs again, and the dried FPC flexible circuit board can be dropped into the collection box 21 by inertia. Because the inner wall of the collection box 21 is provided with a sponge pad 22, the sponge pad 22 can cushion the fall of the FPC flexible circuit board, thereby preventing the FPC flexible circuit board from falling directly into the collection box 21 and being damaged. The sponge pad 22 can avoid this situation. By providing a robotic arm 23, automatic loading of the FPC flexible circuit board can be realized. In the loading process, coding, conveying and drying will be carried out simultaneously, thereby realizing the automation of loading, coding, drying and collection of the FPC flexible circuit board.
