[0002] Screen printing is a technology that uses the basic principle that the screen pattern part of the screen hole is transparent to the paste, and the non-pattern part of the screen hole is not transparent to the paste.

[0003] Reference Figure 1 As shown in the figure, the high-precision laser screen includes a screen frame 101, a polyester screen 102 fixed in the middle of the screen frame 101, and a metal screen 103 arranged on the polyester screen 102. In the manufacturing process of part of the laser screen, the metal screen needs to be etched and refined to obtain a metal screen with a target wire diameter. In the prior art, the laser screen is immersed in an etching liquid, taken out and washed after a period of time, and then the wire diameter of the metal screen is obtained by film thickness detection. However, the thickness of the metal screen cannot be detected in time, and the concentration of the etching liquid changes after a period of use. The reaction time is not unique each time, which leads to the need for manual multiple cycle detection and immersion operation, time-consuming and low efficiency.

[0008] Further, an elastic member is arranged between the floating disc and the upper housing, the elastic member always applies a downward elastic force to the floating disc to move close to the pressure disc, and when the floating disc slides downwardly beyond the opening outer edge of the upper housing, the downward sliding of the floating disc is limited and blocked.

[0009] Further, the pressure sensor is installed on the upper cover through a lifting driver, so that the pressure sensor can move linearly along the vertical direction under the driving of the lifting driver.

When the metal mesh is corroded by the corrosion liquid, the wire diameter and the thickness of the upper and lower end faces of the metal mesh will gradually decrease until the wire diameter of the target metal mesh is reached. At this time, the thickness of the metal mesh is also reduced to the target value, and the float plate moves away from the pressure sensor by a distance, so that the force applied by the float plate to the pressure sensor is reduced.

[0029] In order to make the technical problems to be solved by the present application, the technical solutions and beneficial effects more clearly, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. ​

[0032] It needs to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0033] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, the appearances of the phrase "in one embodiment", "in some embodiments" or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0034] Reference is made to Figures 2 to 10As shown, the steel wire processing equipment provided by the present application is described, which comprises an actuator one 1 and an actuator two 2 above the actuator one 1. The actuator one 1 comprises a lower cover 11 and a pressure plate 12. The lower cover 11 is a cylindrical structure with an open top end and a closed bottom end. The internal cavity of the lower cover 11 is used to hold the corrosion liquid. The pressure plate 12 is contained in the internal cavity of the lower cover 11. The actuator two 2 comprises an upper cover 21, a floating plate 22 and a pressure sensor 24. The upper cover 21 is a cylindrical structure with a closed top end and an open bottom end. The floating plate 22 is contained in the internal cavity of the upper cover 21. The floating plate 22 and the pressure plate 12 are arranged oppositely. The pressure sensor 24 is arranged at one end of the floating plate 22 away from the pressure plate 12. The lower cover 11 can move up and down in the vertical direction. The upper cover 21 can also move up and down in the vertical direction. In the embodiment not shown in the figure, the lower cover 11 can be connected to a linear lifting mechanism to drive the lower cover 11 to rise and fall relative to the ground. Similarly, the upper cover 21 is connected to another linear lifting mechanism to drive the upper cover 21 to rise and fall relative to the ground. The screen 100 can be placed between the lower cover 11 and the upper cover 21. In the embodiment not shown in the figure, a support relative to the ground can be arranged between the lower cover 11 and the upper cover 21. The screen 100 can be detachably mounted on the support. When the upper cover 21 is lowered and the lower cover 11 is raised at the same time, the metal mesh 103 is enclosed in the working cavity composed of the internal cavity of the upper cover 21 and the internal cavity of the lower cover 11. At the same time, the floating plate 22 and the pressure plate 12 are respectively abutted on the upper and lower end faces of the metal mesh 103. At this time, the floating plate 22 is pushed by the pressure plate 12 and abutted on the pressure sensor 24, so that the pressure sensor 24 detects the first pressure value. When the metal mesh 103 is corroded by the corrosion liquid, the wire diameter and the thickness of the upper and lower end faces of the metal mesh 103 gradually decrease until the wire diameter of the target metal mesh 103 reaches the target size. At this time, the thickness of the metal mesh 103 also decreases to the target value correspondingly. The floating plate 22 moves away from the pressure sensor 24 by a distance, so that the force applied by the floating plate 22 to the pressure sensor 24 decreases. At this time, the pressure sensor 24 obtains the second pressure value. Therefore, whether the wire diameter of the metal mesh 103 reaches the target requirement can be quickly judged when the pressure sensor 24 obtains the second pressure value, which effectively improves the processing efficiency compared with the prior art.

[0035] It can be understood that whether the wire diameter of the metal mesh 103 reaches the target requirement can be known by comparing the second pressure value with the data in the database. The data in the database is the value detected by the pressure sensor 24 corresponding to the metal mesh 103 with different wire diameters. The first pressure value is used for reference to determine whether the pressure sensor 24 works normally.

[0036] AsFigure 3 and Figure 6 As shown in FIG. 1, in some embodiments, the floating plate 22 is slidingly connected to the upper cover 21 in the vertical direction, and the floating plate 22 can be lifted by the buoyancy of the etching liquid, and the actuator 1 further comprises a soft shell 13 with ductility, which is covered on the outer circumferential side of the pressing plate 12, so that the inner cavity of the lower cover 11 and the space outside the soft shell 13 form a water chamber 111 for storing the etching liquid, and the outer side of the lower cover 11 is further provided with an interface 6 communicating with the inner cavity of the soft shell 13, so that when the inner cavity of the soft shell 13 is pressurized or depressurized through the interface 6, the soft shell 13 can be controlled to expand outward or contract inward, and when the soft shell 13 expands outward, the volume of the water chamber 111 decreases, or when the soft shell 13 contracts inward, the volume of the water chamber 111 increases, as shown in FIG. 2. Figure 8 As shown in FIG. 2, when the upper cover 21 and the lower cover 11 are clamped on the upper and lower end faces of the polyester screen 102 of the screen 100, and the floating plate 22 and the pressing plate 12 are respectively abutted on the upper and lower end faces of the metal screen 103, the soft shell 13 is cyclically inflated and deflated through the interface 6, so as to control the cyclic expansion and contraction of the soft shell 13, which will force the volume of the water chamber 111 to cyclically decrease and increase, so that the liquid level of the etching liquid in the water chamber 111 cyclically rises and falls, and when the liquid level of the etching liquid rises and contacts the floating plate 22, the floating plate 22 is lifted away from the metal screen 103 by a distance under the action of the buoyancy, and when the liquid level of the etching liquid falls and separates from the floating plate 22, the floating plate 22 loses the buoyancy and thus falls and abuts on the metal screen 103. Through the above design, the floating plate 22 cyclically moves up and down, on the one hand, the cyclic rising and falling of the etching liquid will continuously flush the metal screen 103, and the cyclic lifting and falling of the floating plate 22 will also generate an impact force on the metal screen 103 and the etching liquid, so as to promote the reaction substances on the outer layer of the metal screen 103 to separate from the metal screen 103, thereby accelerating the etching treatment of the metal screen 103, and on the other hand, the etching liquid can be mixed and homogenized to avoid the uneven corrosion of the metal screen 103 caused by the inconsistent concentration distribution of the etching liquid. Specifically, the soft shell 13 is made of corrosion-resistant rubber material.

[0037] As shown in FIG. 2, Figure 4 and Figure 6As shown, in some embodiments, an elastic element 23 is provided between the floating disk 22 and the upper cover 21. The elastic element 23 always applies a spring force to the floating disk 22 to move downward toward the pressure plate 12, and the downward sliding of the floating disk 22 is limited and blocked when the floating disk 22 moves downward past the outer edge of the opening of the upper cover 21. Specifically, a sliding rod 221 is connected to the end of the float 22 away from the pressure plate 12. The sliding rod 221 is slidably connected to the upper cover 21. The elastic element 23 is a helical spring, which is sleeved on the sliding rod 221. One end of the helical spring abuts against the sliding rod 221, and the other end abuts against the upper cover 21. The end face of the sliding rod 221 near the float 22 faces the side of the upper cover 21 away from the float 22. Thus, when the float 22 moves downward past the outer edge of the opening of the upper cover 21, the end face of the sliding rod 221 near the float 22 abuts against the side of the upper cover 21 away from the float 22, thereby limiting and blocking the downward sliding of the sliding rod 221 and preventing the sliding rod 221 from driving the float 22 to continue moving downward. Specifically, the end of the sliding rod 221 near the pressure sensor 24 is provided with a tip 222 for abutting against the pressure sensor 24.

[0038] like Figure 4 and Figure 6 As shown, in some embodiments, the pressure sensor 24 is mounted on the upper housing 21 via a lifting driver 25, enabling the pressure sensor 24 to move linearly in the vertical direction under the drive of the lifting driver 25, such as... Figure 9 As shown, when the floating roof 22 repeatedly moves up and down, the pressure sensor 24 can be moved upward by the lifting drive 25, thus moving it away from the slide bar 221 on the floating roof 22. This prevents the slide bar 221 connected to the floating roof 22 from frequently hitting the pressure sensor 24. Figure 8 As shown, specifically, when it is necessary to detect the data of the pressure sensor 24, the lifting driver 25 drives the pressure sensor 24 to descend into position, so that the pressure sensor 24 abuts against the slide bar 221 connected to the floating plate 22.

[0039] like Figure 8 and Figure 9As shown, in some embodiments, a limit piece 26 is arranged on the upper cover 21 near the position of the pressure sensor 24, the lower end of the limit piece 26 is located above the lower end of the pressure sensor 24 when the lifting driver 25 drives the pressure sensor 24 to descend to the position, and the lower end of the limit piece 26 is located below the lower end of the pressure sensor 24 when the lifting driver 25 drives the pressure sensor 24 to ascend to the position, so that when the pressure sensor 24 needs to detect data, the lifting driver 25 drives the pressure sensor 24 to descend to the position, and meanwhile, the limit piece 26 can avoid interfering with the contact between the pressure sensor 24 and the slide rod 221 connected to the floating plate 22, and when the floating plate 22 repeatedly rises and falls, the pressure sensor 24 does not need to detect data, and the limit piece 26 limits and blocks the slide rod 221 connected to the floating plate 22, so as to avoid accidental impact of the floating plate 22 on the pressure sensor 24 when the floating plate 22 repeatedly rises and falls.

[0040] In some embodiments, the pressure plate 12 can move linearly relative to the lower cover 11 in the vertical direction, on the one hand, the pressure plate 12 can be controlled to rise to clamp the metal mesh 103 with the floating plate 22 when needed, so as to complete the data detection of the pressure sensor 24, and on the other hand, through the rising of the pressure plate 12, the pressure plate 12 drives the soft shell 13 to stretch, so that the inner cavity of the soft shell 13 occupies a part of the space of the water chamber 111, thereby forcing the liquid level of the corrosion liquid in the water chamber 111 to move upward until contacting the metal mesh 103, and through the descending of the pressure plate 12, the soft shell 13 loses the stretching force and thus shrinks, so that the space of the water chamber 111 originally occupied by the inner cavity of the soft shell 13 is released, forcing the liquid level of the corrosion liquid in the water chamber 111 to move downward, on the one hand, the corrosion liquid is separated from the metal mesh 103 to stop the reaction, and on the other hand, the liquid level of the corrosion liquid can be controlled to descend below the lower cover 11 of the upper cover 21, so as to prevent the corrosion liquid from leaking out when the lower cover 11 and the upper cover 21 are separated.

[0041] Specifically, the lower end of the pressure plate 12 is connected with an execution rod 121, and the execution rod 121 is connected with a linear driver, so that the linear driver drives the execution rod 121 to drive the pressure plate 12 to move linearly in the vertical direction.

[0042] As shown, Figure 1 In some embodiments, the lower cover 11 is provided with an inlet 112 for accessing the corrosion liquid and an outlet 113 for discharging the corrosion liquid.

[0043] As shown, Figure 10As shown, sealing rings 3 are provided at the opening edges of the upper cover 21 and the lower cover 11. When the upper cover 21 and the lower cover 11 are pressed onto the polyester mesh 102, the sealing rings 3 are deformed and pressed onto the polyester mesh 102 to fill the holes of the polyester mesh 102 and achieve excellent sealing effect. Specifically, the outer end face of the sealing ring 3 is provided with two concentrically arranged annular sealing lips 31. When the upper and lower sealing rings 3 abut against each other, the two sealing rings 3 and the sealing lips 31 form an annular sealing cavity 7. A stamping interface 5 is provided on the upper cover 21 or the lower cover 11 to communicate with the sealing cavity 7. High pressure medium can be injected into the sealing cavity 7 through the stamping interface 5 to ensure that the sealing cavity 7 is maintained at a high pressure state higher than that of the working cavity. In this way, the near-end sealing surface 4 formed by the abutment between the sealing ring 3 and the polyester mesh 102 is not prone to leakage of corrosive liquid.

[0044] The wire processing equipment provided in this embodiment of the invention first refers to... Figure 6 As shown, in the initial state, the upper cover 21 and the lower cover 11 are separated vertically, as... Figure 7 and Figure 8 As shown, the upper cover 21 then moves downward and the lower cover 11 moves upward until the upper and lower covers 21 and 11 are clamped between the upper and lower end faces of the polyester mesh 102 of the screen 100. The float 22 is driven downward by the upper cover 21 and elastically abuts against the upper surface of the metal mesh 103 under the elastic force of the elastic element 23. The actuator 121 drives the pressure plate 12 to move upward into place, so that the float 22 and the pressure plate 12 abut against the upper and lower end faces of the metal mesh 103 respectively. Here, the inlet 112 is connected to the corrosive liquid, and the port 6 releases air, causing the soft shell 13 to contract. The pressure sensor 24 moves downward into place and detects the first pressure value, such as Figure 9 As shown, the pressure sensor 24 then rises, and the interface 6 is cyclically charged and deflated, causing the floating plate 22 to move up and down repeatedly. Every certain period of time, when the floating plate 22 is in the lower position, the pressure sensor 24 moves down to detect data until the data detected by the pressure sensor 24 reaches the second pressure value, completing the corrosion process. The pressure plate 12 moves down, then the lower cover 11 moves down, and the upper cover 21 moves up. After rinsing, the screen 100 is removed and replaced with a new screen 100 to be processed.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
