[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Embodiment 1, by Figure 1-Figure 2 It is given that a roller pressing device provided by an embodiment of the utility model includes a symmetrically arranged base frame 1, the upper ends of the two base frames 1 are respectively installed with support seats 2, the upper ends of the two support seats 2 are respectively connected with support plates 3, the upper ends of the two support plates 3 are respectively connected with first bearing seats 4, a fixed roller 5 is provided between the two first bearing seats 4, the upper ends of the support plates 3 on both sides are respectively connected with adjustment mechanisms 6, and a movable roller 7 is provided between the two adjustment mechanisms 6.

[0020] The adjusting mechanism 6 includes a support column 601, which is plugged into the corresponding hole on the support plate 3. The first locking nut 602 is connected to the threaded part of the lower part of the support column 601, and the upper end of the support column 601 is connected to a positioning block 603. The upper end of the positioning block 603 is connected to an adjusting rod 604. The lower part of the adjusting rod 604 is a smooth section, and the upper part of the adjusting rod 604 is a threaded section.

[0021] A spring 605 is sleeved on the outside of the adjusting rod 604 and located on the outside of the smooth section. A lifting seat 606 is provided on the upper end of the spring 605. The lifting seat 606 is movably sleeved on the smooth section at the bottom of the adjusting rod 604. The upper end of the lifting seat 606 is connected to a connecting plate 607. The upper end of the connecting plate 607 is connected to a bushing 608. The inside of the bushing 608 is connected to a threaded sleeve 609. The threaded sleeve 609 is threadedly matched with the threaded section at the top of the adjusting rod 604. A handle 610 is fixedly sleeved on the upper part of the threaded sleeve 609.

[0022] One side of the connecting plate 607 is connected to a guide rod 612 via a second locking nut 611. The lower portion of the guide rod 612 passes through the positioning block 603 and is movably embedded in a hole on the positioning block 603.

[0023] A fixed plate 613 is connected to one side of the lifting seat 606, and a second bearing seat 614 is installed at the lower end of the fixed plate 613. The movable roller 7 is rotatably installed inside the second bearing seat 614. The upper end of the second bearing seat 614 is connected to a sensor base plate 615, and a tension sensor 616 is installed at the upper end of the sensor base plate 615. Protective plates 617 are connected to both sides of the lower end of the fixed plate 613.

[0024] Working principle: In the initial state, the handle 610 drives the threaded sleeve 609 to move upward, thereby driving the bushing 608, the connecting plate 607, the lifting seat 606, the fixed plate 613 and the second bearing seat 614 to rise to the highest position. In this way, the movable roller 7 can be raised to the highest position, so that there is a certain gap between it and the fixed roller 5;

[0025] The tension sensor 616 is mounted on the sensor base plate 615 and is used to monitor the downward pressure exerted by the movable roller 7 on the copper foil in real time;

[0026] Pressure adjustment process: When the downward pressure of the movable roller 7 on the copper foil needs to be adjusted, the operator rotates the handle 610 to drive the threaded sleeve 609 to rotate on the threaded section of the adjustment rod 604, so that the threaded sleeve 609 moves up and down along the threaded section of the adjustment rod 604;

[0027] The movement of the threaded sleeve 609 drives the lifting seat 606 and the fixed plate 613 to move up and down through the connecting plate 607, thereby pushing the movable roller 7 downward toward or upward away from the fixed roller 5;

[0028] During this process, the spring 605 plays a role of buffering and resetting, and the guide rod 612 plays a guiding role, ensuring that the movable roller 7 can move smoothly and remain stable after reaching the set position;

[0029] Pressure quantification and feedback: When the movable roller 7 descends to the specified position, the tension sensor 616 monitors the downward pressure exerted by the movable roller 7 on the copper foil in real time and converts the pressure signal into an electrical signal output. The electrical signal can be transmitted to the control system (not shown in the figure) to read the reading of the tension sensor 616 and ensure that the readings on both sides are consistent;

[0030] Since the downward pressure of the movable roller 7 is precisely controlled and quantified, the uniformity and consistency of the electroplating layer can be ensured, thereby improving product quality;

[0031] In summary, the roller pressure device achieves precise quantification and automatic adjustment of the roller pressure through innovative structural design and the introduction of intelligent components, thereby improving the accuracy and efficiency of copper foil electroplating.
