[0058] Principle: when it is necessary to use the pressure maintaining machine to maintain the pressure of the flexible circuit board, first, a plurality of flexible circuit boards are placed on the top of the jig main body 7, then the jig main body 7 is placed inside the feeding port 2, so that the bottom of the jig main body 7 is located on the top of the belt, the first motor 33 is controlled to work, so that the output shaft of the first motor 33 drives the first belt pulley 37 to rotate, the first belt pulley 37 drives a plurality of second belt pulleys 310 to rotate through a belt, at this time, when the jig main body 7 placed on the upper side of the belt moves to one side of the top of the first photoelectric sensor 311, the first photoelectric sensor 311 detects that the jig main body 7 moves to one side of the top of the limiting frame 35, then the push rod end of the air cylinder 34 extends, the push rod end pushes the limiting frame 35 to move upwards, so that the limiting frame 35 blocks the jig main body 7, at this time, the code scanning gun 39 scans the plurality of flexible circuit boards, after the scanning is completed, the push rod end of the air cylinder 34 drives the limiting frame 35 to move downwards, and the jig main body 7 moves to one side of the second support frame 83 under the power of the first motor 33;

[0059] The second motor 81 drives the output shaft to rotate, the output shaft drives the lead screw 84 to rotate, the lead screw 84 is screwed with one of the second connecting frames 82, so that the second connecting frame 82 slides in the track groove of the slide rail, and the second connecting frame 82 drives the second support frame 83 to move; at this time, the interval between the two second support frames 83 can be adjusted, the second motor 81 is controlled to rotate by different angles, so that the belt on one side of the second motor 81 is the same as the width of the jig main body 7; at this time, the output shaft of the third motor 87 is controlled to rotate, the third motor 87 drives the fourth belt pulley 88 to rotate, and the jig main body 7 is driven to move to the lower side of the left pressure maintaining assembly 6 through the belt; when the third photoelectric sensor 85 detects that the jig main body 7 moves to the lower side of the pressure maintaining assembly 6, the work of the third motor 87 is stopped at this time;

[0060] At this time, the push rod end of the electric cylinder 52 is controlled to extend, the push rod end of the electric cylinder 52 drives the first horizontal plate 57 to move upwards, the first horizontal plate 57 drives the quick change disc 55 and the push plate 58 to move upwards, so that the push plate 58 drives the jig main body 7 to move upwards, and the plurality of flexible circuit boards at the top of the jig main body 7 are in contact with the bottom of the pressing head 610; at this time, the pressing head 610 drives the connecting column 69 to move and penetrate on one side of the second horizontal plate 62, so that the spring 68 is compressed, and when the spring 68 is compressed, the rotating screw rod 64 is rotated, so that the screw rod 64 moves downwards along the inner wall of the fixed frame 66, and the spring 68 is compressed by different lengths, so that the pressure of the pressing head 610 on the flexible circuit board can be adjusted;

[0061] The elastic force is transmitted to the pressure sensor 67, the pressure sensor 67 transmits the pressure signal of the pressing head 610 pressing the flexible circuit board to the pressure amplifier 9, and after the pressing head 610 presses the flexible circuit board for a certain time, the push rod end of the left electric cylinder 52 is retracted at this time, so that the push plate 58 drives the jig main body 7 to move downwards, so that the bottom of the jig main body 7 is in contact with the belt on one side of the top of the second support frame 83 again;

[0062] At this time, the power of the third motor 87 moves the jig main body 7 to the lower side of the right pressure maintaining assembly 6, and the right pressure maintaining assembly 6 cooperates with the lifting assembly 5 to continue to pressurize the jig main body 7; after the pressure maintaining time requirement is met, the lifting assembly 5 moves the jig main body 7 downwards, so that the jig main body 7 is in contact with the belt on one side of the second support frame 83, and the flexible circuit board located at the top of the jig main body 7 is sent out from the side of the discharge port 4 to the outside of the rack 1; during the pressure maintaining, the pressure sensor 67 detects the pressure of the pressing head 610 and the flexible circuit board; when the pressure is within the required range, the display screen on one side of the rack 1 displays OK; when the pressure of the flexible circuit board does not meet the requirement, the display screen on one side of the rack 1 displays NG; at this time, the pressure maintaining result of the flexible circuit board can be judged;

[0063] When different sizes of flexible circuit boards need to be pressure maintained, only the output shaft of the second motor 81 needs to be controlled to rotate at different angles, at which time the different width jig bodies 7 can be conveyed;

[0064] At the same time, when different flexible circuit boards on the top of different jig bodies 7 need to be pressure maintained, only the quick-change disc 55 needs to be controlled to separate, and then the push plate 58 is removed, the corresponding push plate 58 is installed on the top of the quick-change disc 55, at which time the different push plates 58 can be quickly replaced, so as to pressure maintain the different jig bodies 7.

At the same time, by adjusting the rotation angle of the output shaft of the second motor 81, the width of multiple jig bodies 7 can be compatible, so as to pressure maintain the flexible circuit boards of different sizes, thereby improving the quality consistency of the pressure maintained flexible circuit boards.

[0066] Through the accurate detection of the first photoelectric sensor 311 and the third photoelectric sensor 85, it can be ensured that the jig body 7 is operated at the correct position and time, such as scanning, moving and pressure maintaining. In addition, by controlling the extension and retraction of the push rod of the electric cylinder 52, the contact pressure and pressure maintaining time of the flexible circuit board and the pressure head 610 can be accurately controlled, so as to ensure the quality of the pressure maintaining processing.

[0067] The pressure sensor 67 can monitor the pressure between the pressure head 610 and the flexible circuit board in real time, and transmit the pressure signal to the pressure amplifier 9, so as to display the pressure maintaining result on the display screen in real time. When the pressure is within the required range, OK is displayed, and when the pressure does not meet the requirements, NG is displayed. The real-time monitoring and feedback mechanism can timely find and correct the problems in the pressure maintaining process, so as to ensure the product quality.

[0068] The quick-change disc 55 can quickly replace the different push plates 58, so as to be compatible with multiple jig bodies 7 and flexible circuit boards, which not only improves the utilization rate of the equipment, but also reduces the time cost of replacing the push plate 58, and enhances the adaptability and flexibility of the equipment.
