Description

Technical Field

[0001] This utility model relates to the field of FFC ribbon cable inkjet printing technology, specifically to an inkjet printing device for FFC ribbon cable production. Background Technology

[0002] FFC (Flexible Flat Cable) cables allow for flexible selection of the number and spacing of wires, making wiring easier, significantly reducing the size of electronic products, lowering production costs, and improving production efficiency. They are ideally suited for data transmission cables between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment. During FFC cable production, inkjet printing is used for marking. Existing technology includes patent CN 216817969U, which discloses a marking device for FFC cable production. This device includes a worktable, a conveying mechanism on the worktable, and a marking mechanism on the conveying mechanism. It also includes a support plate, an adjusting plate, a first adjusting rod, a second adjusting rod, a connecting plate, a connector, rollers, a spring-loaded telescopic plate, and a spring on the worktable. The support plates are arranged in four groups, two to two opposite each other on both sides of the conveying mechanism. This invention utilizes rollers and spring-loaded telescopic plates. The spring-loaded telescopic plates, due to their elasticity, adhere to the conveying mechanism and restrict the position of one side of the FFC cable. The rollers apply pressure from the upper end of the FFC cable, ensuring its flatness on the conveying mechanism. As the conveying mechanism drives the FFC cable, the rollers rotate synchronously under pressure, ensuring stable transport of the FFC cable. However, this device lacks a drying component after coding the FFC cable, resulting in the coding being in a wet state. This may lead to blurred coding due to contact with other equipment during later processing. Therefore, we propose a coding device for FFC cable production. Utility Model Content

This can effectively solve the problems in the background art.

A limiting plate is slidably connected in a groove one opened on the top wall of the limiting seat. A limiting plate two is slidably connected in a groove two opened on the side of the limiting plate one near the center of the conveyor. This allows for movement offset and limiting of the FFC ribbon coding conveyor on the conveyor in the FFC ribbon production coding device.

[0011] Furthermore, each of the slots on the top wall of the limiting seat is slidably connected to a slide block, and each slide block is threadedly connected to a stud 1 in the middle.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This embodiment provides a technical solution: a coding device for FFC cable production, including a coding station 1, with a conveyor 3 and a coding machine 4 respectively mounted on the upper side of the coding station 1, and also including a microcontroller 2, located outside the coding station 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply, and the output terminal of the microcontroller 2 is electrically connected to the input terminals of the conveyor 3, the coding machine 4, and the fan 53 respectively. Two limiting seats 6 are provided on the upper ends of both the front and rear sides of the conveyor 3, and a limiting plate 7 is slidably connected in a groove opened on the top wall of the limiting seat 6. The limiting plate 7 is close to the conveyor 3. Each of the two sliding grooves on one side of the center of the conveyor 3 is slidably connected to a limiting plate 8. Each of the through grooves 9 on the top wall of the limiting seat 6 is slidably connected to a slide block 10. Each slide block 10 has a threaded stud 11 in its middle. The lower end of each stud 11 is rotatably connected to the upper side of the adjacent limiting plate 8 via a bearing 3. Each stud 11 has a handwheel 12 at its upper end. Each of the walls of the limiting seat 6 away from the center of the conveyor 3 has a threaded stud 13. The end of each stud 13 near the center of the conveyor 3 is rotatably connected to the adjacent limiting plate 7 via a bearing 4. The other end of each stud 13 is... With handwheel 14, when performing inkjet printing on the FFC cable, the microcontroller 2 starts the conveyor 3. The conveyor 3's belt drives the FFC cable from right to left for inkjet printing. Simultaneously, rotating handwheel 14 causes stud 13 to rotate. Stud 13, through its threaded connection to the wall of the limiting seat 6, drives the corresponding limiting plate 7 to move along the longitudinal center of the chute. The longitudinal movement of the FFC cable on the conveyor 3 is limited by two adjacent limiting plates 7, thus preventing the FFC cable from being damaged during transport. The conveyor belt of conveyor 3 experiences longitudinal slippage, causing a misalignment in the coding position with the inkjet printer 4. Simultaneously, rotating handwheel 12 causes stud 11 to rotate. Stud 11, through a threaded connection, drives limit plate 8 to slide vertically down the slide groove 2, thereby limiting the vertical movement of the FFC cable conveyor on conveyor 3 and improving the coding accuracy of the FFC cable. Microcontroller 2 starts inkjet printer 4, which uses inkjet technology to perform coding on the FFC cable on the conveyor belt of conveyor 3 below inkjet printer 4. The device also includes a drying mechanism 5.

[0022] Drying mechanism 5 includes a drying shell 51, an air inlet pipe 52, a fan 53, a main pipe 54, an air outlet pipe 55, and a reciprocating assembly 56. The drying shell 51 is located on the upper left side of the inkjet printer 1. The fan 53 is located on the upper side of the drying shell 51. The air inlet of the fan 53 is equipped with an air inlet pipe 52, and the air outlet of the fan 53 is equipped with a main pipe 54. The lower end of the main pipe 54 is equipped with five branch pipes, and the rear end of each branch pipe is equipped with an air outlet pipe 55 through a rotary joint. The reciprocating assembly 56 is located between the air outlet pipe 55 and the drying shell 51. The drying mechanism 5 also includes a heating element 57, which is located on the upper wall of the main pipe 54. The input end of the heating element 57 is electrically connected to the output end of the microcontroller 2. The reciprocating assembly 56 includes a first rotating shaft 561, a first connecting rod 563, and a second rotating shaft 564. Connecting rod 565 and rotating shaft 561 are respectively located on the rear side of the air outlet pipe 55. The other end of rotating shaft 561 is rotatably connected to the rear wall of drying shell 51 through bearing 1. Connecting rod 563 is provided on the outer rear end of rotating shaft 561. The upper end of connecting rod 563 is rotatably connected to rotating shaft 564 through bearing 2. A connecting rod 565 is provided between rotating shaft 564. The reciprocating assembly 56 also includes a disc 562, guide groove 566, eccentric column 567 and motor 568. Motor 568 is located on the rear side of drying shell 51. The input end of motor 568 is electrically connected to the output end of microcontroller 2. The rear wall of drying shell 51 is rotatably connected to disc 562 through rotating shaft 3. The output shaft of motor 568 is fixedly connected to the rear end of rotating shaft 3. An eccentric column 567 is provided at the front eccentric position, and a guide groove 566 is provided at the lower end of the connecting rod 563 in the middle. The front end of the eccentric column 567 is slidably connected to the guide groove 566. The FFC ribbon cable after inkjet printing enters the drying shell 51 along with the conveyor belt 3. The microcontroller 2 starts the fan 53 so that the external gas enters the main pipe 54 through the air inlet pipe 52. At the same time, the microcontroller 2 starts the heating element 57 to heat the gas flowing in the main pipe 54. The heated gas is discharged through the branch pipe and the rotary joint through the air outlet of the air outlet pipe 55, thereby performing hot air drying on the FFC ribbon cable after inkjet printing on the conveyor belt 3, accelerating the solidification speed of the inkjet printing on the FFC ribbon cable. At the same time, the microcontroller 2 starts the motor 568 so that its output shaft drives the rotating shaft 3 to rotate. Shaft 3 drives the eccentric column 567 to rotate via disk 562. During the rotation of the eccentric column 567, through the sliding connection between itself and the guide groove 566, the connecting rod 563 in the middle reciprocates around the corresponding axis 561. During this process, the connecting rod 563 in the middle, through shaft 564 and connecting rod 565, drives the remaining connecting rods 563 to reciprocate around the corresponding axis 561 using the parallelogram rule. Shaft 561 drives the corresponding air outlet pipe 55 to reciprocate, thereby increasing the hot air drying range of the air outlet pipe 55 on the FFC ribbon after inkjet printing on the conveyor belt 3, and further improving the drying speed of the inkjet printing on the FFC ribbon. This device uses hot air drying.This process dries the inkjet printing on the FFC cable. Furthermore, by extending the hot air drying range through a transmission element, the device further enhances the drying effect on the inkjet printing on the FFC cable, effectively preventing scratches and blurring of the inkjet printing.

[0023] The working principle of the inkjet printing device for FFC ribbon cable production provided by this utility model is as follows: When performing inkjet printing on the FFC ribbon cable, the microcontroller 2 starts the conveyor 3. The conveyor belt of the conveyor 3 drives the FFC ribbon cable to be inkjet printed from right to left. At the same time, the handwheel 14 is rotated to drive the stud 13 to rotate. The stud 13 is threadedly connected to the wall of the limiting seat 6, thereby driving the corresponding limiting plate 7 to move along the slide groove towards the longitudinal center of the device. The longitudinal movement of the FFC ribbon cable on the conveyor 3 is limited by the two adjacent limiting plates 7, thereby preventing the FFC ribbon cable from being over-transported. During the process, longitudinal slippage occurs between the inkjet printer and the conveyor belt of conveyor 3, causing a shift in the inkjet printing position of the subsequent inkjet printer 4. Simultaneously, rotating handwheel 12 causes stud 11 to rotate. Stud 11, through a threaded connection, drives limit plate 8 to slide vertically down chute 2, thereby vertically limiting the movement of the FFC cable on conveyor 3 and improving the accuracy of the inkjet printing on the FFC cable. Microcontroller 2 then starts inkjet printer 4, which uses inkjet technology to print the FFC cable on the conveyor belt of conveyor 3 below it. The printed FFC cable then moves along the conveyor belt of conveyor 3. As the air enters the drying chamber 51, the microcontroller 2 starts the fan 53, allowing external air to enter the main pipe 54 through the air inlet pipe 52. Simultaneously, the microcontroller 2 activates the heating element 57 to heat the air flowing through the main pipe 54. The heated air is then discharged through the outlet of the air outlet pipe 55 via the branch pipe and rotary joint, thus performing hot air drying on the FFC ribbon cable after inkjet printing on the conveyor belt 3, accelerating the solidification speed of the inkjet printing on the FFC ribbon cable. Simultaneously, the microcontroller 2 starts the motor 568, causing its output shaft to drive the rotating shaft 3 to rotate. The rotating shaft 3, through the disc 562, drives the eccentric column 567 to rotate. During the rotation of the eccentric column 567... Through the sliding connection between itself and the guide groove 566, the connecting rod 563 in the middle reciprocates back and forth around the corresponding rotating shaft 561. During this process, the connecting rod 563 in the middle drives the remaining connecting rods 563 to reciprocate back and forth around the corresponding rotating shaft 561 through the rotating shaft 564 and connecting rod 565, using the parallelogram rule. The rotating shaft 561 drives the corresponding air outlet pipe 55 to reciprocate back and forth, thereby increasing the range of hot air drying of the FFC ribbon after inkjet printing on the conveyor belt 3 by the air outlet pipe 55, and further improving the drying speed of the inkjet printing on the FFC ribbon.

[0024] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32, the conveyor 3 can be a GTX-003 micro electric conveyor belt, the inkjet printer 4 can be an A180-HD2 handheld inkjet printer, the fan 53 can be an F4-72, the motor 568 can be a 130SZ01, and the heating element 57 can be an MCH ceramic heating element. The microcontroller 2 controls the operation of the conveyor 3, the inkjet printer 4, the fan 53, the motor 568, and the heating element 57 using methods commonly used in the prior art.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
