[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, an embodiment of the present application provides a laser plate-making machine. The laser plate-making machine comprises a platform 10, a carrier 20, a laser assembly 40 and a positioning assembly 30. The carrier 20 is arranged on the platform 10 and is used to place a screen 100 to be processed; the laser assembly 40 is arranged on the platform 10 and is located above the carrier 20. The laser assembly 40 can move relative to the platform 10 along a first direction to expose a target pattern on the screen 100 to be processed; the positioning assembly 30 is arranged on the platform 10 and comprises a stopper 301, and the stopper 301 is located above the carrier 20; the stopper 301 can move along a height direction ( Figure 1 The stopper 301 is configured to move toward and away from the carrier 20 in the first direction (the Z direction in the platform 10), that is, the stopper 301 can move up and down. When the mesh plate 100 to be processed is placed on the placement portion, the stopper 301 moves to contact the mesh plate 100 to be processed. The stopper 301 is used to apply a force to the mesh plate 100 to move the processed mesh plate downward, so that the mesh plate 100 to be processed is relatively fixed to the carrier 20, that is, the position of the mesh plate 100 to be processed is fixed; wherein, the first direction (the length direction of the platform 10, such as Figure 1 The X direction in the second direction ( Figure 1 The Y direction in the figure) is perpendicular to the height direction of the platform 10.

[0036] The platform 10 is the area where the laser plate-making machine places the carrier 20. The placement portion is the plane on the carrier 20 where the screen 100 to be processed is placed. The plane can be a whole horizontal plane or a plane group formed by multiple small planes.

[0037] A coordinate system is established with the length direction of the platform 10 as the X-axis, the width direction of the platform 10 as the Y-axis, and the height direction of the platform 10 as the Z-axis.

[0038] The above-mentioned laser component 40 is mainly used to perform exposure imaging on the screen plate 100 to be processed to form a target pattern. Usually, the laser component 40 is connected to a computer. The computer imports the target pattern, confirms the target pattern on the computer, converts the format using the software provided by the computer, and then enters the software provided by the laser platemaking machine for operation. After the screen plate 100 to be processed is positioned, exposure imaging is performed.

[0039] It should be noted that the above-mentioned screen plate 100 to be processed does not belong to a laser plate-making machine.

[0040] Before the stopper 301 contacts the screen 100 to be processed, the screen 100 to be processed and the carrier 20 need to be aligned in the first direction and the second direction ( Figure 1 The position of the mesh plate 100 to be processed is determined by determining the position of the mesh plate 100 to be processed.

[0041] Before the laser plate-making machine processes the stencil 100, it is necessary not only to meet the positioning accuracy requirements of the stencil 100 to be processed, but also to meet the levelness requirements, that is, the flatness requirements for the stencil 100 to be processed are also relatively high. In this way, if the stencil 100 to be processed is directly placed on the platform 10 for positioning, the processing accuracy and flatness requirements for the platform 10 are relatively high, the processing difficulty is large, and the cost is high. Compared with directly placing the mesh 100 to be processed on the platform 10, the mesh 100 to be processed is placed on the placement part through the carrier 20. In this way, it can be achieved by simply improving the process processing accuracy (including dimensional accuracy and flatness requirements) and precise positioning of the carrier 20. On this basis, not only is it beneficial to achieve rapid and precise positioning of the mesh 100 to be processed through the placement part, which is beneficial to product processing accuracy, but also the area of ​​the placement part of the carrier 20 can be changed to adapt to the processing of meshes 100 to be processed of different sizes, or only the carrier 20 is replaced to achieve the processing of meshes 100 to be processed of different sizes, thereby improving the versatility of the laser platemaking machine. At the same time, the modification structure is less and the cost is lower, so that the laser platemaking machine can achieve the purpose of improving both processing accuracy and versatility.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, the supporting member 20 includes a supporting plate 21 and a guide rail 22 arranged on the supporting plate 21, the side of the guide rail 22 away from the supporting plate 21 is a placement portion, and the guide rail 22 extends along the second direction so that the mesh plate 100 to be processed can move relative to the guide rail 22; a first cylinder 23 is provided on the supporting plate 21, and the moving part of the first cylinder 23 moves along the guide rail 22 to limit the movement of the mesh plate 100 to be processed in the second direction.

[0043] The moving part is in strip shape and extends in the first direction. When the moving part of the first cylinder 23 approaches along the guide rail 22 until it abuts against the edge of the side of the mesh plate 100 to be processed away from the stopper 301 in the second direction, it can fully contact the side of the mesh plate 100 to be processed, thereby reducing the risk of the mesh plate 100 to be processed tilting in the placement portion.

[0044] Compared with placing the mesh plate 100 to be processed directly on the carrier plate 21, by placing the mesh plate 100 to be processed indirectly on the carrier plate 21 through the guide rail 22, the contact area between the placement part and the mesh plate 100 to be processed is reduced, and the friction between the two is reduced, so that the mesh plate 100 to be processed can be easily moved relative to the carrier 20. At the same time, a first cylinder 23 is arranged on the guide rail 22, so that the moving part can move along the guide rail 22 in the second direction. In this way, after the mesh plate 100 to be processed is placed on the placement part, the movement of the mesh plate 100 to be processed in the first direction, the second direction and the height direction of the platform 10 can be limited by the joint action of the moving part of the first cylinder 23 and the stopper 301, so as to realize the three-dimensional positioning of the mesh plate 100 to be processed, which is conducive to improving the processing accuracy of the mesh plate 100 to be processed.

[0045] like Figure 2 to Figure 5 As shown, in some embodiments, the positioning assembly 30 includes multiple power cylinders 31, the piston rods of the power cylinders 31 are parallel to the height direction of the platform 10, and the piston rods are connected to the stopper 301; the side of the platform 10 in the first direction is provided with a power cylinder 31, and the side of the platform 10 in the second direction is provided with a power cylinder 31.

[0046] The power cylinder 31 disposed on the side of the platform 10 along the second direction is generally referred to as the first power cylinder 32. Specifically, the first power cylinder 32 is disposed on the edge of the platform 10 along the second direction. Figure 2 and Figure 3 shown.

[0047] The power cylinder 31 disposed on the side of the platform 10 along the first direction is generally referred to as the second power cylinder 33. Specifically, the second power cylinder 33 is disposed on the edge of the platform 10 along the first direction. Figure 4 and Figure 5 shown.

[0048] The power cylinder 31 is an actuator that converts hydraulic or pneumatic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, a deceleration device can be omitted, and there is no transmission gap, and the motion is smooth. According to the principle of providing pressure, the power cylinder 31 can be divided into a cylinder (pneumatic cylinder), a hydraulic cylinder, and an electric cylinder.

[0049] By arranging power cylinders 31 on the sides of the platform 10 in the first direction and the second direction, when the mesh plate 100 to be processed is placed on the placement portion, the adjacent two sides of the mesh plate 100 to be processed can be well in contact with the carrier 20, which not only improves the positioning accuracy of the mesh plate 100 to be processed, but also reduces the probability of deformation of the mesh plate 100 to be processed during the processing, thereby improving the processing accuracy.

[0050] like Figure 1 to Figure 5As shown, four power cylinders 31, i.e., four second power cylinders 33, are provided on the side of the platform 10 along the first direction away from the laser assembly 40, and the four second power cylinders 33 are arranged at intervals along the second direction; five power cylinders 31, i.e., five first power cylinders 32, are provided on the first side of the platform 10 along the second direction, and the five first power cylinders 32 are arranged at intervals along the second direction.

[0051] A plurality of power cylinders 31 are arranged on both adjacent sides of the platform 10, so that when the stopper 301 contacts the mesh plate 100 to be processed, the force applied to the mesh plate 100 to be processed is distributed more evenly, which is beneficial to improving the flatness of the mesh plate 100 to be processed and further improving the processing accuracy.

[0052] It should be noted that, in addition to the number of the first power cylinder 32 and the second power cylinder 33 being 5 and 4 respectively, the number of the first power cylinder 32 and the second power cylinder 33 can be 2, 3, 4, 5, 6, 7, etc., and the specific number needs to be determined according to the size of the platform 10 in the first direction and the second direction, so as to surround the two adjacent sides of the platform 10, which is not specifically limited here. In addition, since the first power cylinders 32 are arranged along the first direction, the number of the first power cylinders 32 is usually greater than the number of the second power cylinders 33.

[0053] like Figure 3 and Figure 5 As shown, the power cylinder 31 is a pneumatic cylinder.

[0054] The cylinder can be a conventional basic cylinder including a piston rod, or a cylinder with a guide.

[0055] By using an air cylinder as the power cylinder 31 , the positioning assembly 30 has a relatively low cost while meeting the positioning accuracy requirement, which is beneficial to controlling the cost of the laser platemaking machine.

[0056] The following description will be given by taking the power cylinder 31 as an air cylinder as an example.

[0057] Of course, the power cylinder 31 may be a hydraulic cylinder or an electric cylinder in addition to being a pneumatic cylinder.

[0058] like Figure 3 As shown, in some embodiments, the stopper 301 includes a first plate 302 and a second plate 303, the first plate 302 is vertically connected to the end of the piston rod, and the second plate 303 is vertically connected to a side edge of the first plate 302, that is, the stopper 301 is an L-shaped structure. Usually, the power cylinder 31 having the connection structure of the stopper 301 and the first power cylinder 32 is connected.

[0059] In this way, after the mesh plate 100 to be processed is placed on the placement portion, the second plate 303 can limit the mesh plate 100 to be processed from moving along the second direction toward the edge of the supporting plate 21. On this basis, when the moving portion of the first cylinder 23 approaches along the guide rail 22 until it abuts against the edge of the side of the mesh plate 100 to be processed away from the stop portion 301 in the second direction, the mesh plate 100 to be processed abuts between the stop portion 301 and the moving portion. Under the joint action of the second plate 303 and the moving portion, the mesh plate 100 to be processed and the supporting member 20 are relatively fixed.

[0060] like Figure 5 As shown, in some embodiments, the stopper 301 includes a first plate 302, and the first plate 302 is vertically connected to the end of the piston rod. That is, the stopper 301 is a stopper plate. Usually, the stopper 301 is connected to the second power cylinder 33, and the second power cylinder 33 is arranged on one side edge of the platform 10 along the first direction.

[0061] It should be noted that the piston rods of the power cylinders 31 on the two adjacent sides of the platform 10 may also be connected to the same stopper 301 , which is not specifically limited here.

[0062] As shown in the figure, in some embodiments, a rolling member 50 is provided at an edge of the platform 10 away from the laser assembly 40 along the first direction. The rolling member 50 is located on a side of the power cylinder 31 away from the bearing plate 21 .

[0063] By providing a rolling member 50 on one side of the platform 10 away from the laser assembly 40 along the first direction, when the stencil 100 to be processed is loaded, the rolling member 50 can be used to replace the sliding with the relative rolling of the rolling member 50, so as to realize the mobile loading of the stencil 100 to be processed, save manpower, thereby improving the loading speed, and the same is applicable when the stencil is unloaded. In other words, the loading and unloading speed of the stencil is improved.

[0064] like Figure 2 As shown, the rolling element 50 is a roller, and the axis of the rolling element 50 is parallel to the second direction. In this way, during the loading process of the screen 100 to be processed, the screen 100 to be processed drives the rolling element 50 to rotate around the second direction, thereby increasing the speed of the screen 100 to be processed moving in the first direction, and further increasing the loading and unloading speed.

[0065] During the design of the rolling element 50, the length of the rolling element 50 is designed to be greater than or equal to the size of the carrier plate 21 in the second direction. In this way, the rolling element 50 covers the carrier plate 21, that is, covers the size of the placement portion in the second direction. During the feeding process of the mesh plate 100 to be processed, the mesh plate 100 to be processed can be completely in contact with the surface of the rolling element 50 in the second direction, which increases the effective contact area between the mesh plate 100 to be processed and the rolling element 50, which is conducive to further improving the feeding speed.

[0066] In addition to being configured as a roller, the rolling element 50 may also include a central axis and a roller, wherein the roller rotates relative to the central axis, or a plurality of rotating parts that can rotate around the second direction may be configured, which is not specifically limited herein.

[0067] like Figure 6 and Figure 7 As shown, in some embodiments, the laser assembly 40 includes a box 41 and a laser (not shown in the figure) disposed in the box 41, and the box 41 moves relative to the platform 10 along a first direction through a guide mechanism 12; the laser can move relative to the box 41 in a direction perpendicular to the height direction of the platform 10.

[0068] The laser plate-making machine further includes a frame 11, on which the platform 10 is fixed, and the frame 11 surrounds the platform 10. The box 41 is mounted on the frame 11, and the opening of the box 41 faces the carrier 20, so that the laser emitted by the laser irradiates the screen 100 to be processed through the opening, thereby exposing and imaging the screen 100 to be processed.

[0069] The guide mechanism 12 is a mechanism that can realize the movement of the box 41 relative to the platform 10 in the first direction. Usually, the edge of the frame 11 is slidably connected to the opening 42 of the box 41 by the guide mechanism 12, so that the box 41 can move in the first direction to realize the positioning of the laser assembly 40. The guide mechanism 12 can be a moving module. The moving module includes a motor, a track and a slider, and the slider moves along the track under the drive of the motor. Usually, the track is set at the edge of the frame 11, the slider is fixedly connected to the box 41, and the slider cooperates with the track to realize the movement of the box 41 relative to the platform 10 in the first direction. In one embodiment, a moving module can be set on both sides of the frame 11 along the second direction, so as to realize the movement of the box 41 relative to the platform 10 in the first direction. In another embodiment, a moving module can also be set only between one side of the frame 11 and the box 41, and only the track and the slider cooperate between the other side of the frame 11 and the box 41, so as to realize the movement of the box 41 relative to the platform 10 in the first direction. The guide mechanism 12 may be a movable module driven electrically, or may be a pneumatic movable mechanism capable of movement, which is not specifically limited here.

[0070] The movement of the box 41 drives the laser to move above the screen 100 to be processed, so that the box 41 can stay at different positions of the carrier 20. After the position of the box 41 is determined, the laser emitted by the laser is exposed and imaged on the screen 100 to be processed through the opening 42, thereby realizing the laser processing of one or more screens 100 to be processed on the placement part, or the laser processing of one screen from different positions, which has strong versatility.

[0071] Usually, in order to facilitate checking the working condition of the laser, a transparent window (not shown in the figure) is set on one side wall of the box 41. In this way, the staff can check the working condition of the laser through the transparent window at any time when the laser is working to ensure whether the laser is in good condition.

[0072] Usually, in order to facilitate the installation and maintenance of the laser, a door (not shown in the figure) is provided on one side wall of the box 41. When the laser is working, the door is in a closed state. When the laser fails, the door is opened to facilitate the staff to repair and replace the laser, and at the same time, it is convenient for the installation of the laser.

[0073] It should be noted that the transparent window can be opened on the door, and can also be set on other side walls of the box body 41, which is not specifically limited here.

[0074] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
