Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-2 In this embodiment of the invention, a rolling pressure roller device includes a frame 1, on which a pressure roller assembly 2 and a power unit 4 for driving the pressure roller assembly 2 to reciprocate are disposed.

[0019] The frame 1 includes a slide module 11 and a support plate 12 disposed above the slide module 11. The two ends of the support plate 12 are fixedly connected to the slide module 11 via support plates.

[0020] The pressure roller assembly 2 includes a pressure roller assembly bracket 24 slidably connected to the frame 1. A pressure roller 21 is provided at the upper end of the pressure roller assembly bracket 24, and sliding bushings 22 are provided at both ends of the pressure roller 21. The pressure roller assembly bracket 24 is provided with sliding grooves 242 for accommodating the sliding bushings 22. The pressure roller assembly bracket 24 includes upright plates 241 located on both sides, and a fixed horizontal plate is connected between the upright plates 241 on both sides. Sliding grooves 242 are provided on both upright plates 241. The sliding grooves 242 include a rectangular groove with an opening at the upper end and an arc-shaped groove at the lower end. The diameter of the arc-shaped groove is not less than the width of the rectangular groove, and the width of the rectangular groove is not less than the diameter of the sliding bushing. In this embodiment, the sliding bushing 22 is installed from the upper part of the sliding groove 242 and embedded in the side wall of the pressure roller assembly bracket 24 with a slight gap, so that it can slide freely horizontally and vertically.

[0021] The pressure roller 21 is detachably connected to a counterweight shaft 23 at both ends. The counterweight shaft 23 is coaxially arranged with the pressure roller 21. In this embodiment, the pressure roller 21 is provided with a rotating shaft at both ends, and a sliding bushing 22 is sleeved on the rotating shaft. The end of the rotating shaft is provided with a threaded hole for connecting the counterweight shaft 23, and a connecting screw is provided at one end of the counterweight shaft 23.

[0022] The power unit 4 includes a drive motor, the output shaft of which is connected to a lead screw 41 via a coupling. The upper end of the slide module 11 is provided with a slide rail, and a support slider 13 is slidably connected on the slide rail. The lead screw 41 passes through the support slider 13 and is threadedly connected to the support slider. The lower end of the upright plate 241 is fixedly connected to the upper end of the support slider 13. The support plate 12 is located above the support slider 13. That is to say, during use, the support slider 13 will provide certain support to the support plate 12 above it to prevent the support plate from bending under pressure.

[0023] The upper end of the tray 12 has a groove 121 for placing materials. The depth of the groove 121 is slightly less than the thickness of the substrate (such as a stainless steel plate), and the width of the groove 121 is approximately equal to the width of the substrate (such as a stainless steel plate). When the pressure roller assembly 2 slides through the groove 121 area, the substrate and the sample are pressed and bonded together without slippage. A positioning device 3 is provided between the side of the pressure roller assembly support 24 and the slide module 11. The positioning device 3 includes a limit stop plate 31 located on the outside of the pressure roller assembly support 24 and a limit switch 32 located on the slide module 11. There are two limit switches 32 located at both ends of the groove 121. There are also two limit stops 31 located at the front and rear ends of the pressure roller assembly 24 and arranged in conjunction with the two limit switches 32. The limit switches 32 are signal-connected to the control cabinet 5, which is signal-connected to the power unit 4. The control cabinet 5 is equipped with an input component, which is a touch input screen. In this embodiment, the pressing pressure, pressing time, and speed of the pressing rollers during the pressing process are first set according to the test and substrate to be pressed. Then, the parameters are adjusted according to the set parameters. First, the pressing pressure is adjusted by adjusting the pressing weight. In this embodiment, the pressing pressure is adjusted by installing counterweight shafts 23 of different weights at both ends of the pressing roller 21. The pressing time is achieved by controlling the running time of the motor of the power unit 4. The pressing speed is achieved by controlling the running speed of the motor of the power unit. How to control the running time and running speed of the motor is a common technique in the field and will not be described in detail here.

[0024] After adjustment, the substrate and sample are placed in the groove 121. Then, the motor is started by controlling the control cabinet 5. The motor drives the pressure roller assembly bracket 24 to reciprocate. During the reciprocating motion, when the pressure roller assembly bracket 24 moves to one end, for example, during forward movement, the pressure roller assembly bracket 24 moves forward one end, and during the movement, it applies a horizontal force to the sliding bushing 22, thereby pushing the sliding bushing 22 forward with the pressure roller assembly bracket 24. Since the sliding groove 242 on the pressure roller assembly bracket is wider than the sliding bushing 22, the sliding groove 242 can only provide horizontal support for the sliding bushing 22 and cannot provide vertical support. With the support of the pressure roller, the weight of the pressure roller will be pressed onto the groove 121, which is the upper part of the substrate and the sample. When the pressure roller assembly bracket 24 moves forward to the limit position, the limit stop 31 at the front end of the pressure roller assembly bracket 24 triggers the corresponding limit switch 32. After the limit switch 32 is triggered, it sends a signal to the control cabinet 5. After receiving the signal, the control cabinet 5 controls the motor to reverse, driving the pressure roller assembly 2 to move in the opposite direction. When the reverse limit position is reached, the limit switch at the corresponding position will also be triggered. Thus, the reciprocating motion of the pressure roller assembly 2 can be controlled by the limit switches at both ends, and the reciprocating motion of the pressure roller assembly 2 can be used to press the substrate and the sample together.
