Description

Technical Field

[0001] This application relates to the field of laser plate making machine technology, and in particular to a grid frame fixing device for a laser plate making machine. Background Technology

[0002] As the core equipment for screen printing stencil production, the laser stencil machine consists of three parts: mesh, frame, and photosensitive emulsion. The frame is used to fix and stretch the mesh to ensure stable mesh tension. The mesh, as the carrier of the photosensitive emulsion, directly affects the printing accuracy. The photosensitive emulsion is cured by laser exposure to form the desired pattern. The frame support structure is the core component for fixing the mesh.

[0003] In related technologies, traditional grid frame support structures typically use movable mounting rods and fixed mounting rods with adjustable spacing via slide rails to accommodate grid frames of different lengths. The support rods are responsible for supporting the grid frame, which is then fixed using adhesive granules, iron sheets, or positioning pins.

[0004] However, when changing to screens of different thicknesses, such as 20mm, 32mm or 40mm, it is necessary to repeatedly adjust the position of the screen frame and refocus the laser head. The focal plane error must be controlled within ±0.1mm, otherwise it will lead to exposure pattern shift, size ratio distortion and image blurring. The operation process is cumbersome and inefficient.

[0005] Existing technology discloses a frame fixing device for a digital PCB manufacturing machine. The frame includes a mesh and a core material for fixing the mesh. The frame fixing device includes a mesh support and a core material fixing component. The mesh support supports the mesh. After the mesh is placed on the mesh support, the core material fixing component fixes the core material according to the height of the frame. This technology eliminates the need to adjust the nozzle regardless of the thickness of the core material. It only requires fixing the core material by adjusting the core material according to the height of the frame, thereby improving the efficiency and accuracy of adjusting the distance between the mesh and the nozzle.

[0006] However, the above method relies on mesh support members to support the mesh. The mesh core material that fixes the mesh is prone to sagging between the mesh support members and the mesh core material. As the carrier of the photosensitive emulsion, the mesh can easily affect the printing quality, and the uniformity and precision of the laser-exposed photosensitive emulsion are difficult to guarantee. Utility Model Content

[0007] In order to improve the processing quality of laser plate making machine, this application provides a grid frame fixing device for laser plate making machine.

[0008] The grid frame fixing device for a laser plate making machine provided in this application adopts the following technical solution: A frame fixing device for a laser plate making machine includes a base and a frame fixing assembly. The frame fixing assembly is installed on the upper surface of the base and is used to adapt to and fix frames of different sizes. The frame fixing assembly includes several support rods and several sliders. The support rods are located above the base and can slide back and forth along the length direction of the base. The sliders are slidably disposed on the support rods.

[0009] By adopting the above technical solution, several sliding support rods are set, and several sliding sliders are set on each support rod. The moving support rods can adapt to the length of the screen frame, and the moving sliders can adapt to the width of the screen frame, thereby achieving the fixation of screen frames of different sizes. The sliders support the screen mesh, which can adapt to the screen frame core material of different thicknesses. The sliding support rods can drive the sliders to support the four corners of the screen mesh, reducing the focal plane error caused by the deformation due to the sagging of the screen mesh, thereby improving the printing quality and ensuring the uniformity and accuracy of the laser exposure photosensitive emulsion.

[0010] Preferably, it also includes a sliding assembly, which includes a slide rail and a sliding seat. Two slide rails are provided. The slide rails are horizontally fixed on the upper surface of the base. The sliding seat is slidably disposed on the slide rails. The support rod is fixed on the sliding seat.

[0011] By adopting the above technical solution, the sliding component, through the cooperation of two horizontally fixed slide rails and sliding seats, realizes the smooth sliding function of the support rod and provides stable guidance. The sliding seat, by sliding on the slide rails, enables the support rod to move flexibly in the horizontal direction, reduces the frictional resistance during the sliding process, and improves the smoothness of the movement. At the same time, the double slide rails enhance the overall stability of the support rod.

[0012] Preferably, the sliding assembly further includes a connecting plate, the connecting plate being provided with screw holes, the upper surface of the sliding seat being provided with a second threaded hole, the position of the screw holes being adapted to the position of the second threaded hole, the connecting plate being provided with a first threaded hole, and the support rod being provided with a clearance hole, the position of the first threaded hole being adapted to the position of the clearance hole.

[0013] By adopting the above technical solution, the screw rod is sequentially inserted into the screw hole to the second threaded hole to fix the connecting plate and the sliding seat, thereby achieving the initial positioning and fixing of the connecting plate and the sliding seat. Then, the bolt is screwed into the first threaded hole from the side of the connecting plate facing the sliding seat, and extends through the clearance hole on the support rod. Finally, the bolt and the support rod are locked together by tightening the nut, thereby fixing the connecting plate and the support rod.

[0014] Preferably, the support rod is provided with a sliding groove, and the bottom of the slider is provided with a sliding strip, which is slidably connected to the sliding groove.

[0015] By adopting the above technical solution, the support rod is equipped with a sliding groove and a sliding strip that is slidably connected to the bottom of the slider, which realizes the linear guidance of the slider sliding along the support rod, restricts the slider's offset or rotation, and improves the stability of the slider's movement.

[0016] Preferably, it also includes a wire frame support assembly, wherein two wire frame support assemblies are provided, both of which are located around the wire frame fixing assembly. One of the wire frame support assemblies is slidably disposed on the slide rail along the horizontal direction of the base, and the other wire frame support assembly is fixedly connected to the base.

[0017] By adopting the above technical solution, one of the mesh frame support components can be slidably set on the slide rail along the horizontal direction of the base to limit the mesh frame according to actual processing needs, thereby adapting to different mesh processing needs. The mesh frame support component fixedly connected to the base provides a stable reference support point to ensure the starting reference position of laser exposure.

[0018] Preferably, the mesh frame support assembly includes an L-shaped plate and a limiting post. The L-shaped plate includes a horizontal plate and a vertical plate, which are vertically fixed. One end of the limiting post is vertically fixed to the vertical plate, and the other end of the limiting post is engaged with the mesh frame.

[0019] By adopting the above technical solution, the other end of the limiting post penetrates through the side wall of the mesh frame and is snapped into the mesh frame, thereby realizing the limiting and fixing of the mesh frame and the mesh in the direction of movement of the support rod, reducing the displacement of the mesh frame with mesh in the direction of movement of the support rod caused by external force during the processing.

[0020] Preferably, the wire mesh frame fixing assembly further includes a drive cylinder, which is slidably disposed on the base and located in the middle of the two slide rails, and the piston rod of the drive cylinder is fixedly connected to one of the wire mesh frame support assemblies.

[0021] By adopting the above technical solution, the drive cylinder is used as a power source and is fixedly connected to the mesh frame support assembly. It can synchronously drive the mesh frame support assembly to move horizontally, thereby quickly adjusting according to the position of the mesh frame so that the limiting post and the mesh frame can be inserted and matched, and the slider and the limiting post together clamp the mesh frame and fix its position.

[0022] Preferably, the mesh frame support assembly is provided with a locking element, which is fixedly connected to the drive cylinder.

[0023] By adopting the above technical solution, the locking component is fixedly connected to the drive cylinder to lock and fix the drive cylinder and the mesh frame support assembly, and further lock and fix the mesh frame with mesh, so that the mesh frame with mesh is prevented from shifting during processing. When it is necessary to adjust the processing position, the locking component can be released, and the drive cylinder and the mesh frame support assembly can slide on the base to further adjust the processing position.

[0024] Preferably, the bottom of the wire mesh frame support assembly is provided with an adjustment component and a support plate. The adjustment component is located at the bottom of the wire mesh frame support assembly. The adjustment component includes a cylindrical pin and a linear bearing. The linear bearing is fixedly connected to the support plate. The cylindrical pin is slidably disposed within the linear bearing. The cylindrical pin is fixedly connected to the lower surface of the horizontal plate. The support plate is slidably disposed on the slide rail along the horizontal direction of the base.

[0025] By adopting the above technical solution, the vertical guiding movement of the mesh frame support assembly is achieved by utilizing the sliding of the cylindrical pin within the linear bearing. Since the cylindrical pin is fixedly connected to the lower surface of the horizontal plate, and the limiting post is inserted into the mesh frame, under the weight of the mesh frame support assembly, the limiting post drives the mesh frame to press down vertically, causing the mesh to fit against the slider. Since the support plate slides horizontally along the base on the slide rail, it can simultaneously drive the support plate to further move the mesh frame support assembly horizontally, thereby quickly adjusting the position of the mesh frame so that the limiting post is inserted into the mesh frame, and the slider and the limiting post together clamp the mesh frame, fixing its position.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A frame fixing device for a laser plate making machine achieves the fixing of frames of different sizes by means of a support rod that can slide horizontally along the base and a slider that can slide along the length of the support rod. The slider supports the four corners of the mesh, reducing the probability of mesh sagging, thereby improving printing quality and ensuring the uniformity and precision of the laser-exposed photosensitive emulsion. 2. By cooperating with the slide rail and the sliding seat, the sliding seat slides along the horizontal slide rail, driving the support rod to move, so as to dynamically adjust the mesh frame with mesh of different sizes, reduce frictional resistance, improve the smoothness of movement, and enhance the overall stability of the support rod movement.

[0039] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.

[0040] This application discloses a wire mesh frame fixing device for a laser plate making machine. (Refer to...) Figure 1A frame fixing device for a laser plate making machine includes a base 1 and a frame fixing assembly 3. The frame fixing assembly 3 is installed on the upper surface of the base 1 and is used to adapt to and fix frames of different sizes. The frame fixing assembly 3 includes several support rods 31 and several sliders 32. In this embodiment, two support rods 31 are provided and four sliders 32 are provided. The two support rods 31 are located above the base 1 and can slide back and forth along the length direction of the base 1. Each support rod 31 is matched with two sliders 32, and the two sliders 32 are slidably disposed on the support rod 31.

[0041] This demonstrates that by using two sliding support rods 31, and then setting two sliding sliders 32 on each support rod 31, the length of the support rods 31 can be adapted to the length of the screen frame, and the width of the screen frame can be adapted to the width of the screen frame, thereby achieving the fixation of screen frames of different sizes. The screen mesh is supported by the sliders 32, and the screen mesh abuts against the sliders 32. The sliding support rods 31 can drive the sliders 32 to support the four corners of the screen mesh, reducing the focal plane error caused by the deformation due to the sagging of the screen mesh, thereby improving the printing quality and ensuring the uniformity and precision of the laser-exposed photosensitive emulsion.

[0042] Reference Figure 2 Correspondingly, a frame fixing device for a laser plate making machine also includes a sliding component 4. The sliding component 4 is disposed on the upper surface of the base 1. The support rod 31 slides horizontally on the base 1 through the sliding component 4. Specifically, the sliding component 4 includes a slide rail 41 and a sliding seat 43. There are two slide rails 41, which are located on both sides of the upper surface of the base 1 respectively. The two slide rails 41 are arranged along the length direction of the base 1 and are parallel to each other. The length of the slide rail 41 is less than the length of the base 1. The sliding seat 43 is slidably connected to the slide rail 41. In this embodiment, there are four sliding seats 43, and each slide rail 41 is slidably connected to two sliding seats 43.

[0043] Reference Figure 3 Furthermore, the sliding assembly 4 also includes a connecting plate 42, and the sliding seats 43 are all fixedly connected to the connecting plate 42. The width of the connecting plate 42 matches the width of the support rod 31, as shown in the reference. Figure 4 The connecting plate 42 is provided with four screw holes 421, which are evenly distributed on the connecting plate 42. The upper surface of the sliding seat 43 is provided with a second threaded hole 431. The position and number of the second threaded hole 431 are adapted to the screw holes 421, and the screw holes 421 pass through the connecting plate 42 and communicate with the second threaded hole 431. A screw rod is sequentially inserted into the screw holes 421 to the second threaded hole 431, so that the screw rod is threadedly engaged with the screw holes 421 and the second threaded hole 431 to fix the connecting plate 42 and the sliding seat 43, thereby achieving the initial positioning and fixation of the connecting plate 42 and the sliding seat 43.

[0044] Reference Figure 5 and Figure 6 Meanwhile, four first threaded holes 422 are provided next to each screw hole 421. The support rod 31 is provided with clearance holes 311. The position and number of clearance holes 311 are also matched with the number of first threaded holes 422. The first threaded holes 422 and clearance holes 311 pass through the connecting plate 42 and the support rod 31. The bolt is screwed into the first threaded hole 422 from the side of the connecting plate 42 toward the sliding seat 43 and extends through the clearance hole 311 on the support rod 31. Finally, the bolt and the support rod 31 are locked together by tightening the nut.

[0045] Therefore, in this embodiment, two support rods 31 are provided. The support rods 31 are fixed to the sliding seats 43 through the connecting plate 42. The sliding seats 43 slide horizontally on the slide rails 41, driving the support rods 31 to slide horizontally on the two slide rails 41, so as to achieve smooth sliding of the support rods 31. The slide rails 41 provide stable guidance for the sliding of the support rods 31, and the sliding seats 43 enable the support rods 31 to move flexibly in the horizontal direction by sliding on the slide rails 41, reducing the frictional resistance during the sliding process and improving the smoothness of the movement. At the same time, the two slide rails 41 enhance the overall stability of the support rods 31.

[0046] Furthermore, in this embodiment, four sliders 32 are provided, and each support rod 31 is slidably connected to two sliders 32. The two sliders 32 are distributed at both ends of the support rod 31. Specifically, the slider 32 is a rectangular block, and the width of the slider 32 matches the width of the support rod 31. A sliding strip 321 is provided at the bottom of the slider 32, and a sliding groove 312 is provided on the support rod 31. The width of the sliding groove 312 matches the width of the sliding strip 321. The sliding strip 321 and the sliding groove 312 are slidably connected, and the side wall of the sliding strip 321 abuts against the groove wall of the sliding groove 312. The lower surface of the slider 32 abuts against the upper surface of the support rod 31.

[0047] This demonstrates that by setting a sliding slider 32 on the surface of the support rod 31, the vertical direction of the support rod 31's movement can be flexibly adjusted. The slider 32 can slide along the length of the support rod 31, and at the same time, the slider 32 supports the mesh, allowing the operator to adjust the vertical position of the slider 32 and the movement direction of the support rod 31 according to the actual processing requirements of the mesh, and flexibly change different mesh frames with mesh. The support rod 31 can fit against the mesh frame, and then the slider 32 is pushed into the corners of the mesh frame respectively. The limiting effect of the slider 32 further fixes the mesh to the mesh frame, reducing the sagging of the mesh due to its own weight or external force.

[0048] In addition, it also includes a wire frame support component. There are two wire frame support components 2. Both wire frame support components 2 are set on the periphery of the wire frame fixing component 3. One of the wire frame support components 2 is slidably set on the slide rail 41 along the horizontal direction of the base 1 through the sliding component 4. The other wire frame support component 2 is fixedly connected to the base 1.

[0049] This illustrates that one of the mesh frame support components 2 can be slidably mounted on the slide rail 41 along the horizontal direction of the base 1 to limit and fix the mesh frame according to actual processing requirements, thereby adapting to different mesh processing needs. The mesh frame support component 2, which is fixedly connected to the base 1, serves as a reference fulcrum to ensure the starting reference position of laser exposure.

[0050] Reference Figure 7 Specifically, the wire mesh support assembly 2 includes an L-shaped plate 21 and limiting posts 22. The L-shaped plate 21 includes a horizontal plate 211 and a vertical plate 212, both of which are plate-shaped structures. Four limiting posts 22 are provided, horizontally set on the vertical plate 212 and vertically fixed to it. The limiting posts 22 are inserted into the wire mesh. The wire mesh support assembly 2 also includes a support plate 9. The L-shaped plate 21 slides vertically on the support plate 9. The support plate 9 is fixedly connected to the sliding seat 43, which slides on the slide rail 41. This achieves the limiting and fixing of the wire mesh and the wire mesh in the direction of movement of the support rod 31, reducing the displacement of the wire mesh with wire mesh in the direction of movement of the support rod 31 caused by external forces during processing.

[0051] Reference Figure 8 and Figure 9 Furthermore, an adjustment component 8 is provided at the bottom of the frame support component 2. The adjustment component 8 includes a cylindrical pin 81 and a linear bearing 82. The linear bearing 82 is fixedly connected to the support plate 9. The cylindrical pin 81 is slidably disposed in the linear bearing 82. At the same time, the cylindrical pin 81 is fixedly connected to the lower surface of the horizontal plate 211. Two sets of adjustment components 8 are provided, and the two sets of adjustment components 8 are located at both ends of the horizontal plate 211.

[0052] This demonstrates that by utilizing the sliding of the cylindrical pin 81 within the linear bearing 82, the vertical guiding movement of the mesh frame support assembly 2 is achieved. Simultaneously, the limiting post 22 is inserted into the mesh frame, and under the weight of the mesh frame support assembly 2, the limiting post 22 drives the mesh frame to press down vertically, causing the mesh to adhere to the slider 32.

[0053] Reference Figure 10In addition, the wire mesh frame fixing assembly also includes a drive cylinder 5. The drive cylinder 5 is slidably mounted on the base 1 and located in the middle of the two slide rails 41. Specifically, the base 1 is provided with a sliding groove 11, which is located in the middle of the slide rails 41. The sliding groove 11 is provided with a mounting seat 6, which is slidably mounted on the sliding groove 11. The piston rod of the drive cylinder 5 is fixedly connected to one of the wire mesh frame support components 2 that slides along the horizontal direction of the base 1 through the sliding component 4. The other end of the drive cylinder 5 is fixedly connected to the mounting seat 6.

[0054] This shows that the drive cylinder 5 serves as a power source and is fixedly connected to the mesh frame support assembly 2. When the drive cylinder 5 slides in the horizontal sliding groove 11, it can simultaneously drive the mesh frame support assembly 2 to move in the horizontal direction, thereby quickly adjusting according to the position of the mesh frame so that the limiting post 22 can be inserted and engaged with the mesh frame. The slider 32 and the limiting post 22 together clamp the mesh frame and fix its position.

[0055] Reference Figure 11 Meanwhile, the mounting base 6 is also equipped with a locking component 7, which is fixed on the mounting base 6 to lock and fix the drive cylinder 5 and the mesh frame support assembly 2, and further lock and fix the mesh frame to prevent displacement of the mesh frame during processing. When it is necessary to adjust the processing position, the locking component 7 can be released, and the drive cylinder 5 and the mesh frame support assembly 2 can slide on the base 1 to further adjust the processing position.

[0056] The implementation principle of the wire mesh fixing device for a laser plate making machine according to the embodiments of this application is as follows: A frame fixing device for a laser plate making machine includes a base, a frame support assembly, and a frame fixing assembly. The frame support assembly is installed on the upper surface of the base and is adapted to support frames of different sizes. The frame fixing assembly includes a support rod and a slider. The support rod is horizontally supported above the base and slides horizontally. The slider is slidably disposed on the support rod. The support rod and the slider are located below the mesh to support the mesh.

[0057] A frame fixing device for a laser plate making machine further includes a sliding component. The sliding component includes a slide rail, a sliding seat, and a connecting plate. The slide rail is arranged along the length of the base, and the sliding seat slides horizontally on the slide rail. The guide effect of the slide rail reduces frictional resistance and ensures the smooth movement of the support rod.

[0058] The screw holes of the connecting plate and the second threaded hole of the sliding seat are initially positioned and fixed. The bolt is screwed into the first threaded hole of the connecting plate from the side of the connecting plate facing the sliding seat, and extends through the clearance hole on the support rod. Finally, the bolt and the support rod are locked together by tightening the nut. The support rod can be flexibly adjusted in the horizontal direction by sliding the sliding seat to adapt to the size requirements of different mesh frames.

[0059] The support rod has a sliding groove on its surface. The slider is a rectangular block with a sliding strip at the bottom. The sliding strip is slidably connected to the sliding groove of the support rod, allowing the slider to move freely along the length of the support rod. The lower surface of the slider abuts against the upper surface of the support rod. The operator can push the slider according to the corner position of the mesh frame to embed the slider into the corner of the mesh frame and fix the mesh, further enhancing the support effect.

[0060] There are two mesh frame support components. One of them works in conjunction with the sliding component through a drive cylinder to achieve sliding along the horizontal direction of the base, while the other mesh frame support component is fixedly connected to the base.

[0061] The mesh frame support assembly consists of an L-shaped plate composed of a horizontal plate and a vertical plate. The limiting post is vertically fixed on the vertical plate. Through the interlocking and cooperation with the mesh frame, the mesh frame and the mesh are limited and fixed in the direction of movement of the support rod, which reduces the displacement of the mesh frame with mesh in the direction of movement of the support rod caused by external forces during the processing.

[0062] In addition, the wire mesh frame fixing assembly also includes a drive cylinder and a mounting base. The base is provided with a sliding groove. The piston rod of the drive cylinder is fixedly connected to one of the wire mesh frame support components that slides horizontally along the base via a sliding component. The other end of the drive cylinder is fixedly connected to the mounting base. The drive cylinder slides along the sliding groove via the mounting base to achieve sliding on the base. The piston rod is fixedly connected to the slidable wire mesh frame support component. The drive cylinder serves as a power source and is fixedly connected to the wire mesh frame support component. When the drive cylinder slides in the horizontal sliding groove, it can simultaneously drive the wire mesh frame support component to move horizontally, thereby quickly adjusting according to the position of the wire mesh frame so that the limiting post and the wire mesh frame can be inserted and engaged. The slider and the limiting post together clamp the wire mesh frame and fix its position.

[0063] The locking component is fixed on the mounting base to lock and fix the drive cylinder and the mesh frame support assembly, and further lock and fix the mesh frame with mesh, so as to reduce the displacement of the mesh frame with mesh during processing. When it is necessary to adjust the processing position, the locking component can be released, and the drive cylinder and the mesh frame support assembly can slide on the base to further adjust the processing position.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
