[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0024] See also Figure 1 In the first aspect, the embodiment of the present application provides a rolling device 100, which can be used to roll screen products such as tablets, mobile phones, car screens, notebook screens, commercial display screens, and TV screens, so that the screens of electronic products fit closely with other components such as back panels, or can be used to roll batteries to make the batteries compact and reduce battery expansion. The rolling device 100 is automatically controlled by a PLC (Programmable Logic Controller) control system.

[0025] See also Figure 1 The rolling device 100 includes a driving mechanism 1, a rolling mechanism 2 and a pressure control mechanism 3. Figure 2 The driving mechanism 1 includes a first driving member 11, a rolling mechanism 2 connected to the output end of the first driving member 11, and the first driving member 11 is used to drive the rolling mechanism 2 to roll and compact the product; the pressure control mechanism 3 is connected to the first driving member 11, and the pressure control mechanism 3 is used to control the output pressure of the first driving member 11. By adding the pressure control mechanism 3, the output pressure of the first driving member 11 can be directly controlled. Since the rolling mechanism 2 is connected to the output end of the first driving member 11, the compacting force applied by the rolling mechanism 2 to the product can be controlled. Compared with the spring, the pressure control mechanism 3 is more sensitive and accurate in controlling the pressure, and can improve the rolling quality of the product.

[0026] See also Figure 2In some embodiments, the driving mechanism 1 includes a lifting assembly 12 , a sliding assembly 13 , a first driving member 11 , a floating joint 14 and a displacement sensor 17 .

[0027] See also Figure 2 In some embodiments, the lifting assembly 12 is connected to the first driving member 11 and the rolling mechanism 2, and the lifting assembly 12 is used to drive the first driving member 11 and the rolling mechanism 2 to simultaneously perform lifting movements to approach or move away from the surface of the product. The provision of the lifting assembly 12 can facilitate adjustment of the position of the rolling mechanism 2 in the height direction.

[0028] Optionally, the lifting assembly 12 may be a screw module, a belt module, a gear rack module or a linear motor module.

[0029] See also Figure 2 Taking the screw module as an example, in some embodiments, the lifting assembly 12 includes a motor 121, a coupling 122, a screw 125, a support seat 123 and a slide 124. The motor 121 is fixed on the support seat 123, the output end of the motor 121 is connected to one end of the screw 125 through the coupling 122, the other end of the screw 125 is connected to the support seat 123 through a bearing, and the slide 124 is connected to the screw 125 in a transmission connection. The motor 121 drives the screw 125 to rotate, and then the screw 125 drives the slide 124 to move. The first driving member 11 and the rolling mechanism 2 are both connected to the slide 124. The lifting assembly 12 is lifted and lowered by components such as the screw 125, and has the advantages of high transmission accuracy, strong bearing capacity and good reliability.

[0030] See also Figure 2 and Figure 3 In some embodiments, the driving mechanism 1 further includes a sliding assembly 13, which is connected to the lifting assembly 12 and the rolling mechanism 2 at the same time, and the first driving member 11 is used to drive the rolling mechanism 2 to slide relative to the lifting assembly 12 through the sliding assembly 13. The sliding assembly 13 is added to enable the rolling mechanism 2 to maintain a stable motion trajectory during the pressing process, avoid deviation or shaking caused by friction or instability, and ensure the stability and accuracy of the pressing operation.

[0031] See also Figure 3 Further, the sliding assembly 13 includes a guide rail 131 and a slide 132 that are slidably connected, the guide rail 131 is fixedly connected to the slide seat 124 of the lifting assembly 12, and the slide 132 is fixedly connected to the rolling mechanism 2. The extension direction of the guide rail 131 is the same as the extension direction of the screw rod 125.

[0032] See also Figure 3Furthermore, the guide rail 131 and the slide 124 are connected via an adapter 133. The adapter 133 is connected to the slide 124, the guide rail 131 is arranged on the adapter 133, and the bottom end of the adapter 133 extends in a direction away from the slide 124, so that the adapter 133 is L-shaped. The L-shaped adapter 133 can limit the lifting movement of the slide 132 to prevent the slide 132 from moving excessively downward.

[0033] See also Figure 2 In some embodiments, the driving mechanism 1 further includes a displacement sensor 17, which is connected to the rolling mechanism 2, and is electrically connected to the lifting assembly 12, and is used to detect the distance between the rolling mechanism 2 and the surface of the product. The displacement sensor 17 feeds back the distance signal to the PLC control device, which in turn controls the lifting assembly 12 to adjust the position of the rolling mechanism 2.

[0034] See also Figure 2 In some embodiments, the output end of the first driving member 11 is connected to the rolling mechanism 2, and the rolling mechanism 2 is located at the bottom end of the first driving member 11. The pressure control mechanism 3 includes a pressure regulating valve 31 and a proportional valve 32. The pressure regulating valve 31 and the proportional valve 32 are both connected to the first driving member 11. The pressure regulating valve 31 and the proportional valve 32 are used to jointly control the output pressure of the first driving member 11. The first driving member 11 can be a cylinder or a hydraulic cylinder. The pressure regulating valve 31 and the proportional valve 32 have high sensitivity and can respond quickly and accurately to the input signal, thereby making the control more precise. The pressure regulating valve 31 and the proportional valve 32 can quickly change the flow and pressure of the fluid to achieve fine control, and thus can accurately control the output pressure of the first driving member 11.

[0035] Take the first driving member 11 as an example of a cylinder. The first driving member 11 includes a first interface and a second interface, the proportional valve 32 is connected to the gas source and the first interface at the same time, and the pressure regulating valve 31 is connected to the gas source and the second interface at the same time. The proportional valve 32 adjusts the air intake of the gas source into the first interface under the control of the PLC control device, thereby controlling the positive pressure of the cylinder, and the pressure regulating valve 31 adjusts the air intake of the gas source into the second interface under the control of the PLC control device, thereby controlling the negative pressure of the cylinder, and there is a pressure difference between the positive pressure and the negative pressure, which is the output pressure of the cylinder. The proportional valve 32 and the pressure regulating valve 31 can achieve pressure control with an output pressure of 1N, thereby improving the accuracy of the control pressure. Exemplarily, the first driving member 11 can be a low-friction cylinder, and the piston of the low-friction cylinder has reduced inertia and damping during movement, which can improve the control accuracy of the cylinder, thereby further improving the control accuracy of the output pressure.

The pressure sensor 33 is used to detect the output pressure of the first driving member 11, and can be fed back to the PLC control device, so that the PLC control device controls the air pressure of the proportional valve 32 and / or the pressure regulating valve 31. Exemplarily, the pressure sensor 33 can be an S-type sensor.

[0037] See also Figure 4 In some embodiments, the driving mechanism 1 further includes a floating joint 14, the top end of which is connected to the bottom end of the first driving member 11, and the bottom end of which is connected to the rolling mechanism 2. The floating joint 14 can make a slight eccentric sliding in the vertical direction of the axis of the first driving member 11, thereby reducing the eccentric load and lateral load on the first driving member 11 caused by the non-vertical installation, and reducing the bending damage of the output end of the first driving member 11.

[0038] See also Figure 4 Specifically, the top end of the floating joint 14 is connected to the bottom end of the pressure sensor 33 through the connecting member 15, and the bottom end of the floating joint 14 is connected to the slide 132 of the sliding assembly 13 through the fixing member 16, thereby indirectly connected to the rolling mechanism 2.

[0039] See also Figure 4 In some embodiments, the rolling mechanism 2 includes a second driving member 21 and a rolling assembly 22 .

[0040] In some embodiments, the second driving member 21 is located at the bottom end of the first driving member 11 and connected to the output end of the first driving member 11, and the rolling assembly 22 is connected to the output end of the second driving member 21. The second driving member 21 is used to drive the rolling assembly 22 to turn. During the rolling process, the product surface may be uneven or the material may be deformed, resulting in uneven surfaces in different parts. By adding the second driving member 21 and adjusting the rolling direction, the rolling assembly 22 can act on different areas, thereby avoiding local overload or relaxation and achieving uniform rolling. The PLC control device controls the rotation direction of the second driving member 21.

[0041] Optionally, the second driving member 21 may be a swing cylinder or a rotary motor. The swing cylinder may be a blade-type swing cylinder, a rack-type cylinder, a gear rack-type cylinder, or a thin rotary cylinder.

[0042] See also Figure 4 Taking the blade-type swing cylinder as an example, the blade-type swing cylinder includes a driving part 211 and a swing table part 212 connected to each other, and the driving part 211 is located at the top of the swing table part 212. Figure 2 and Figure 3One side of the swing table 212 is connected to the slide 132, and the bottom of the swing table 212 is connected to the rolling assembly 22. The driving unit 211 is electrically connected to the PLC control device. Under the control of the PLC control device, the driving unit 211 drives the swing table 212 to rotate, thereby turning the rolling assembly 22.

[0043] See also Figure 4 In some embodiments, the rolling assembly 22 includes a bracket 221, a rotating shaft, and a rolling wheel 222. Both ends of the rotating shaft are connected to the bracket 221, and the rolling wheel 222 is rotatably disposed on the rotating shaft. There can be one or more rolling wheels 222.

[0044] The movement mode of the rolling device 100 of the present application will be further described below with reference to a specific embodiment:

[0045] The lifting assembly 12 drives the first driving member 11 and the rolling mechanism 2 to descend together, so that the rolling wheel 222 of the rolling mechanism 2 contacts the product surface. The proportional valve 32 and the pressure regulating valve 31 control the output pressure of the first driving member 11, so that the rolling mechanism 2 rolls the product surface, and the second driving member 21 can adjust the rolling direction during the rolling process.
