Description

Technical Field

[0001] This utility model belongs to the field of fully open printing screen technology, and in particular relates to a high-strength fully open stainless steel screen forming equipment. Background Technology

[0002] A photovoltaic screen printing plate is one of the tools used to print the grid lines of solar cells. During use, metal paste is formed onto the silicon wafer through the printing holes of the screen, creating metal grid lines. Traditional printing plates typically have a screen on their surface.

[0003] For example, patent application number CN202323173645.9 discloses a screen and a photovoltaic screen. The screen includes a first printing section and a second printing section. The first printing section includes multiple first mesh wires, which are connected end to end to form multiple first mesh openings that penetrate the screen. The second printing section includes multiple second mesh wires, which are connected end to end to form multiple second mesh openings that penetrate the screen. The opening ratio of the second mesh openings is greater than that of the first mesh openings, and the cross-sectional area of ​​the first mesh wires is greater than that of the second mesh wires.

[0004] Existing technologies often have silk threads obstructing the printed patterns, preventing the silver paste from being effectively printed onto the silicon wafer surface, frequently resulting in unevenness or bumps. Furthermore, the strength of these silk threads is insufficient, making them prone to breakage after repeated use, thus impacting overall production efficiency.

[0005] Therefore, some screen designs have emerged that directly cut large openings on metal sheets. Although this can solve the problem of wire obstruction, the openings will still be twisted and deformed during the forming process, even if they are formed by a high-precision laser cutting machine. Therefore, in addition to improving the overall production process, the corresponding forming equipment also needs to be changed.

[0006] CN202210534087.5 disclosed a highly stable device and method for changing screen tension, including a support base and a changing component. The support base has a positioning frame near its edge at the upper end, and a positioning groove is provided at the center of the upper end of the positioning frame. A protruding back plate is provided at the bottom inner side of the positioning groove. The changing component for changing screen tension is placed in the middle of the upper end of the support base.

[0007] Existing technologies, through modifications to the design of multiple components, enable tension adjustment of the screen during mesh forming, tautning it outwards to reduce opening distortion and other issues. However, they still have certain shortcomings in overall use.

[0008] First, the existing device cannot guarantee the uniformity of pressure on all parts of the screen during the outward tensioning and dragging process after the screen is clamped. This can easily cause the overall pressure on the screen to concentrate in one or a few directions, resulting in the screen still twisting and deforming during the cutting process, making it impossible for the device to complete higher precision processing.

[0009] Secondly, even if the screen can complete the uniformity detection of tension or pressure as a whole, the equipment cannot make minute adjustments when the screen pressure is uneven. At this time, it takes a lot of time to manually handle minute pressure changes, which affects the overall production efficiency.

[0010] Finally, the cutting process of the screen generates certain harmful gases, which existing equipment cannot effectively purify, making it easy for operators to be affected by the gases when they turn on the equipment. Utility Model Content

[0011] To overcome the shortcomings of existing technologies, this invention provides a high-strength, fully open stainless steel mesh forming device. Through improvements to the forming equipment, this invention solves the technical problem that existing devices cannot detect and adjust the tension pressure of the mesh, significantly improving the overall processing accuracy of the mesh while reducing worker injuries and improving the overall processing environment.

[0012] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, fully open stainless steel mesh forming device, comprising a counter and a cabinet. The cabinet is located at the upper end of the counter, and a cutting device is located inside the cabinet. Multiple support platforms are rectangularly and slidably distributed on the end face of the counter. Each support platform has an anti-slip pad made of buffer material on its end face. Clamping seats are slidably arranged at the corners between the multiple support platforms. The adjacent ends of the multiple clamping seats are open, and clamping plates are slidably arranged inside. A flexible pad that can be elastically deformed is arranged below the clamping plate at the bottom of the opening of the clamping seat. Multiple distance detectors for detecting whether the substrate is in position are arranged on the outer wall of the opening of the clamping seat on the flexible pad. Multiple reference blocks for improving the sliding stability of the support platform are arranged on the inner side of each support platform. A support base is fixedly arranged on one side of each reference block. A multi-point detection component for detecting the uniformity of the substrate clamping pressure is arranged on the end face of the support base and the reference block. A plate adjustment component is arranged between the multi-point detection components.

[0013] By using clamping seats and flexible pads, the screen can be effectively clamped and stretched outward at its four corners before cutting, reducing the possibility of bending and deformation. The multi-point detection components and the plate adjustment components allow the equipment to detect and fine-tune the tension or tautness pressure, effectively improving the overall processing accuracy and efficiency.

[0014] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, an upwardly inclined heating seat is provided between the two support seats, and multiple air jets are provided on the upper surface of the heating seat. An electric heating mesh plate is provided inside the heating seat.

[0015] By using heating bases and electric heating mesh plates, the efficiency of external gas flow can be improved during the mesh processing to achieve dust reduction, and the mesh can also be preheated to further reduce problems such as opening deformation and cracking.

[0016] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, the multi-point detection component includes a first pressure detector set at the upper end face of each reference block. An abutment plate is slidably arranged above the first pressure detector. A first elastic telescopic tube made of elastic material is connected between the abutment plate and the top of the reference block. When the flexible pad is compressed and elastically deformed to a certain extent, the abutment plate contacts the bottom of the substrate and presses downward to contact the detection end of the first pressure detector.

[0017] By designing flexible pads, abutment plates, and a first pressure detector, the pressure at multiple locations on the screen can be effectively monitored after clamping, allowing staff to make timely adjustments.

[0018] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, the multi-point detection component also includes a plurality of second pressure detectors disposed at the upper end of the support base. A second elastic telescopic tube is connected to the detection end face of each second pressure detector. A first contact head is connected to the upper end of the second elastic telescopic tube. A plurality of rice-shaped particles are disposed at the upper end face of the first contact head. The second pressure detector performs pressure detection when the substrate is clamped.

[0019] By using a first contact head, a second pressure detector, and a second elastic telescopic tube, the detection accuracy can be further improved. It can also track and detect in real time when the screen clamping pressure is adjusted, thus ensuring the accuracy during adjustment.

[0020] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, the plate adjustment component includes mounting slots arranged at an incline on both sides of the upper end of the support base. Each mounting slot is provided with a flexible tube seat on the outside, and a vibration support component is provided inside the flexible tube seat. The vibration support component transmits vibration to the mesh through the flexible tube seat.

[0021] By incorporating sheet material adjustment components and vibration support components, when uneven pressure occurs on the screen, a small amount of vibration can be used to shift the screen towards the direction of lower pressure, thereby improving overall accuracy.

[0022] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, the vibration support assembly includes multiple elastic brackets disposed on the bottom end face of the mounting groove. Each elastic bracket is made of elastic metal material and is bent. A vibrator is disposed on the bent surface of the elastic bracket. A convex plate is disposed on the output end of the vibrator. The convex plate pushes the top of the flexible tube seat outward to form a guide arc surface.

[0023] By incorporating an elastic support, vibrator, and convex panel, the screen can be finely adjusted, and during the cutting process, it can be vibrated to eliminate cutting stress, further reducing the occurrence of problems such as cracks at the screen opening.

[0024] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, a dust collection seat is provided on the end face of the counter between multiple heating seats. The upper surface of the dust collection seat is mesh-shaped, a fan assembly is provided inside the dust collection seat, and an air purifier is provided on one side of the dust collection seat inside the counter.

[0025] By incorporating a vacuum cleaner and purifier, harmful gases generated during the cutting process can be removed immediately, improving the overall processing environment.

[0026] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, a support is provided on one side of the clamping seat on the end face of the counter, and a limiting slide rail is provided on the end face of the support near the clamping seat. A limiting slider is slidably fitted on the limiting slide rail, and the limiting slider is fixedly connected to the bottom of the clamping seat.

[0027] By setting up limit rails and limit sliders, the overall stability is ensured when the clamping seat slides outward and tightens.

[0028] In the above-mentioned high-strength fully open stainless steel mesh forming equipment, a rigid pad is connected to the bottom of the clamping plate inside the clamping seat.

[0029] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0030] (1) By improving the forming equipment, this utility model not only solves the problems of gourd-shaped joints and gaps that are easy to occur in traditional screen printing, but also enables the screen to be fully open. In addition to the good flatness and uniformity of the grid lines after forming, it also greatly reduces the problems of bending and deformation of the opening when the screen is opened, and further improves the overall forming accuracy of the screen.

[0031] (2) By setting up multiple clamping seats and clamping plates, as well as limiting slide rails and anti-slip pads, this utility model enables the screen to be stably clamped at its four corners and subjected to outward tension before laser cutting. This effectively reduces the occurrence of deformation and twisting at the opening of the screen, and improves the forming accuracy and efficiency of the screen opening.

[0032] (3) Through the design of distance detector and multi-point detection components, this utility model enables the pressure applied to the screen by the equipment to be monitored in real time at multiple points during the process of the screen being stretched outward. This allows the staff to adjust it in time when the tension or stretching pressure is uneven, avoid pressure concentration, and further reduce the possibility of deformation of the screen and opening.

[0033] (4) By designing the plate adjustment component and vibration support component, this utility model enables the equipment to make fine adjustments when the pressure of the screen is uneven, reducing the involvement of workers and improving the overall production efficiency. At the same time, after the screen is cut multiple times, it can also be vibrated to eliminate stress, reduce screen opening cracks, and improve the screen yield.

[0034] (5) By setting up a dust collection seat and a purifier, as well as a heating seat and an electric heating mesh plate, this utility model enables the gas outside the mesh plate to circulate quickly during the processing to achieve the purpose of dust removal. The harmful gases generated during processing can be absorbed and purified, improving the processing environment. In addition, the mesh plate can be preheated before cutting to reduce abnormal deformation caused by a sudden increase in surface temperature during cutting and improve the overall surface flatness.

Detailed Implementation

[0048] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0049] Example 1:

[0050] Reference Appendix Figure 1 Appendix Figure 2Appendix Figure 3 and attached Figure 4 A high-strength, fully open stainless steel stencil forming device includes a counter 13, a cabinet 10 on one end face of the counter 13, and two cabinet doors 12 hinged to one side end face of the cabinet 10. Workers can open the cabinet doors 12 to place and retrieve the stencil. A cutting device 14 is installed inside the cabinet 10 on one side of the cabinet doors 12. The cutting device 14 includes multiple conventional moving structures and a cutting end, capable of cutting printing grid holes of different shapes and sizes at different positions on the stencil. It should be noted that the cutting device 14 is not an innovation of this invention; its laser is a femtosecond laser, and the entire device is based on conventional existing technology, capable of high-precision stencil cutting. Therefore, the electrical control method and specific structure of the cutting device 14 will not be elaborated upon in this solution. A control panel 11 is installed on one side end face of the cabinet 10, allowing workers to control and adjust various cutting data of the equipment, similar to the cutting device 14, and is also existing technology.

[0051] Further, see attached document. Figure 3 and attached Figure 6 Each of the four sides of the counter 13 is equipped with a support platform 16. A non-slip mat 17 made of flexible non-slip material is provided in the middle of the upper end of the support platform 16. Multiple non-slip stripes are arranged on the end face of the non-slip mat 17. Multiple third push cylinders 61 are provided below each support platform 16 and on the upper end face of the counter 13. The output ends of the multiple third push cylinders 61 are connected to the bottom end face of the support platform 16. When the substrate needs to be cut, the operator can place the substrate on the end face of the multiple non-slip mats 17, and then the cutting device 14 can perform the cutting process. Before cutting, the output ends of the multiple third push cylinders 61 can push the support platform 16 to move up and down, thereby adjusting the height of the support platform 16 and the substrate on the non-slip mat 17, thereby improving the processing flexibility. The setting of the non-slip mat 17 can reduce the possibility of the substrate slipping and shaking, and improve the stability of the substrate during cutting.

[0052] Further, see attached document. Figure 3 and attached Figure 5Supports 18 are fixedly installed on the end face of the counter 13 between each pair of support platforms 16. The four sets of supports 18 are arranged diagonally at the corners between the four support platforms 16. Each support 18 is bent. A first push cylinder 19 is fixedly installed on the vertical end face of each support 18. A connecting seat 41 is connected to the output end of the first push cylinder 19. The connecting seat 41 is made of flexible buffer metal material. A clamping seat 20 is fixedly installed on one side of the connecting seat 41. The adjacent ends of the four clamping seats 20 are open. A flexible pad 26 is installed at the bottom of the opening of the clamping seat 20. A clamping plate 23 is slidably installed above the flexible pad 26 and inside the clamping seat 20. A rigid pad 60 is fixedly installed on the bottom end face of the clamping plate 23.

[0053] Before the substrate is placed on the end face of the anti-slip pad 17 for cutting, the output ends of multiple first push cylinders 19 push multiple connecting seats 41 and clamping seats 20 toward the four corners of the substrate. At this time, the anti-slip pad 17 and the support table 16 are adjusted by the action of the third push cylinder 61, so that the bottom height of the substrate is slightly higher than the upper end face of the flexible pad 26, so that the multiple clamping seats 20 can insert their openings into the multiple corners of the substrate. When the multiple corners of the substrate are all within the multiple clamping seats 20, the clamping plate 23 will move downward, thereby driving the rigid pad 60 to press against the end face of the substrate, thus clamping the substrate. During this process, the flexible pad 26 is made of anti-slip buffer material and has a certain elastic deformation capability. Therefore, when the rigid pad 60 continuously applies clamping pressure downward, the flexible pad 26 can be used to clamp the substrate. The pad 26 will then elastically deform downwards, pressing the entire substrate downwards until it stabilizes and stops moving. This design improves the overall clamping effect in case the substrate is damaged during clamping, and also absorbs some vibration during cutting, improving cutting accuracy. After the substrate is clamped, the output end of the first push cylinder 19 will retract inwards, thereby driving the connecting seat 41 and the clamping seat 20 to move outwards. This allows the four corners of the substrate held by the clamping seat 20 to be stretched outwards, keeping the substrate in a taut and fixed state. This prevents the pattern from deforming or twisting after grooving. In addition, after the substrate is clamped, the support platform 16 and the anti-slip pad 17 will also move upwards, supporting the substrate at its four sides. This allows the anti-slip pad 17 to absorb and mitigate some vibration during cutting, further improving stability.

[0054] Furthermore, see the attached document. Figure 5A limiting slide rail 27 is fixedly provided on the side end face of the support 18 near the clamping seat 20, and a limiting slider 28 is fixedly provided on the bottom end face of the clamping seat 20. The limiting slider 28 slides in cooperation with the limiting slide rail 27. When the clamping seat 20 is pushed by the output end of the first push cylinder 19, the clamping seat 20 will also drive the limiting slider 28 to slide outside the limiting slide rail 27. Thus, the limiting slide rail 27 and the limiting slider 28 can limit the sliding of the entire clamping seat 20, so that the overall stability of the clamping seat 20 can be greatly improved when the substrate is stretched outward, ensuring the efficiency of substrate stretching.

[0055] A second push cylinder 21 is fixedly installed at the top corner of the clamping base 20. The output end of the second push cylinder 21 is fixedly connected to the top of the clamping plate 23 with its downward orientation. Two sliding holes 51 are respectively provided on the top end face of the clamping base 20 on both sides of the second push cylinder 21. A slide rod 24 is slidably installed in the sliding hole 51. The top of the slide rod 24 is provided with a limit protrusion, and the bottom of the slide rod 24 is fixedly connected to the upper end face of the clamping plate 23. When the substrate needs to be clamped, the output end of the second push cylinder 21 can push the clamping plate 23 to move downward, thereby clamping and fixing the corner of the substrate. During this process, the sliding cooperation between the slide rod 24 and the sliding hole 51 can ensure the stability of the clamping plate 23 sliding up and down.

[0056] Further, see attached document. Figure 5 Two reference blocks 22 are fixedly installed on one side of each tray 16 on the end face of the counter 13. The top end face of the two reference blocks 22 is lower than the horizontal height of the opening of the clamping seat 20. A limiting groove 30 is provided on the end face of the reference block 22 near the tray 16. A guide block 29 is slidably fitted in the limiting groove 30. The guide block 29 is fixedly installed on the bottom end face of the tray 16. Through the sliding fit between the limiting groove 30 and the guide block 29, the tray 16 is more stable when moving up and down. The setting that the top end face of the reference block 22 is lower than the horizontal height of the opening of the clamping seat 20 can also prevent the substrate from being damaged by contact with the reference block 22 when pressed down, thereby improving the overall yield.

[0057] Example 2:

[0058] A high-strength, fully open stainless steel mesh forming device, based on Embodiment 1, is further illustrated in the attached figure. Figure 6 Appendix Figure 9 and attached Figure 10A first pressure detector 42 is provided on the top end face of each of the two reference blocks 22. A first elastic telescopic tube 43 is provided on the outside of the first pressure detector 42 at the upper end face of the reference block 22. A contact plate 62 is connected to one end of the top of the first elastic telescopic tube 43. The contact plate 62 can slide down and contact the detection end of the first pressure detector 42 when there is pressure, so that the first pressure detector 42 can detect the corresponding pressure and pressure change.

[0059] Specifically, during substrate clamping, the support platform 16 and anti-slip pad 17 lift the substrate upwards above the flexible pad 26. Therefore, the abutment plate 62 is not in contact with the substrate at this time. When the clamping plate 23 begins clamping, and the support platform 16 and anti-slip pad 17 fall downwards, the bottom of the substrate will contact the top end face of the abutment plate 62. The end face of the abutment plate 62 and the end face of the flexible pad 26 are at the same height when not under pressure. Subsequently, when the clamping plate 23 pushes the rigid pad 60 to clamp the substrate, causing the substrate to move downwards, the substrate will push the abutment plate 62 downwards, thus... After the first elastic expansion tube 43 undergoes a certain elastic deformation, the abutment plate 62 abuts against the detection end of the first pressure detector 42. At this time, the detection end of the first pressure detector 42 will detect a certain pressure. At this time, the multiple first pressure detectors 42 on the multiple reference blocks 22 will detect the corresponding pressure. Since the first pressure detectors 42 are distributed at multiple points, they can uniformly detect the pressure changes at various positions on the substrate. This allows feedback on whether there are differences in the pressure in various areas of the substrate when it is compressed or stretched outward. This allows for timely adjustments and improves the stretching effect.

[0060] Furthermore, see the attached document. Figure 6 Appendix Figure 9 and attached Figure 10A support base 36 is fixedly installed on one side end face of each reference block 22. Multiple second pressure detectors 44 are installed in the middle of the upper end face of the support base 36. Each second pressure detector 44 has a second elastic telescopic tube 45 made of elastic material at its output end. A first contact head 33 is connected to one top end of the second elastic telescopic tube 45. Multiple semi-elliptical rice-shaped particles 46 are installed on the upper end face of the first contact head 33. The multiple second pressure detectors 44, in conjunction with the support base 36, can serve as an extension of the detection range of the first pressure detector 42. Similar to the first pressure detector 42, the second pressure detectors 44 can also detect the rice-shaped particles 46. When the first contact head 33 is pressed, it detects the pressure. However, unlike the first pressure detector 42, the output end of the second pressure detector 44 is directly connected to the second elastic telescopic tube 45. Therefore, when the first contact head 33 is pressed and moves downward, the second elastic telescopic tube 45 will transmit the pressure change to the second pressure detector 44 immediately, so that the second pressure detector 44 can detect the corresponding pressure change more sensitively, thereby further improving the detection effect. In this solution, the semi-elliptical rice-shaped particles 46 are set so that the top of the first contact head 33 is relatively smooth, and it is also convenient for the substrate to be adjusted in time when the pressure is uneven, thereby improving the processing efficiency.

[0061] Example 3:

[0062] A high-strength, fully open stainless steel mesh forming device, based on Embodiment 1 or 2, is further illustrated in the attached document. Figure 5 Distance detectors 25 are provided on both inner walls of the clamping base 20. The detection end of the distance detector 25 faces the opening of the clamping base 20. The distance detector 25 can detect the distance of the substrate entering the clamping base 20. That is, when the substrate enters the clamping base 20, the distance between the diagonal side of the substrate and the inner wall side of the clamping base 20, or whether the diagonal side of the substrate abuts against the inner wall side of the clamping base 20 can be detected. This setting can determine whether the substrate is placed in the middle and whether the overall clamping area of ​​multiple clamping bases 20 is the same when clamping. This can help detect the overall pressure change of the substrate and make timely adjustments.

[0063] Further, see attached document. Figure 11 and attached Figure 12 The support base 36 has beveled sides. On one side of the beveled surface of the support base 36, on both sides of the end face of the support base 36, there are inwardly recessed mounting grooves 47. Each mounting groove 47 has a flexible tube seat 34 made of flexible material on its exterior. Multiple elastic supports 48 are installed inside the flexible tube seat 34 and connected to the bottom of the mounting groove 47. Each elastic support 48 is connected to… Figure 12Similarly, the bending position is relatively thin, and the elastic support 48 is made of flexible metal material, which has a certain elastic support force. A vibrator 49 is fixedly installed on the bending slope of the elastic support 48. The vibrator 49 is a micro vibrator, which belongs to conventional existing technology. The overall vibration principle of the vibrator will not be elaborated in this solution. A convex plate 50 is connected to the output end of the vibrator 49. The convex plate 50 is arc-shaped. Its arc surface pushes the flexible tube seat 34 outward, so that the part of the flexible tube seat 34 pushed by the convex plate 50 forms a guide arc surface 35.

[0064] Specifically, the multiple mounting slots 47 and flexible tube bases 34 are all inclined outwards towards their respective reference blocks 22. After the substrate is placed and clamped, only most of the guide arc surface 35 is in contact with the bottom surface of the substrate. If the force is uneven at different positions on the bottom of the substrate, the clamping base 20 will reduce the clamping pressure, so that the screen is in a state of being pressed but relatively loose. Then, multiple vibrators 49 can be started. The output end of the vibrator 49 can drive the convex plate 50 to generate a certain vibration in the direction of its respective clamping base 20. Thus, the convex plate 50 can push the substrate on the guide arc surface 35 to arch in its respective direction. Each vibrator 49 and convex plate 50 in each direction is mainly started when the pressure is insufficient at the corresponding position, so that the substrate can be arched in the direction of insufficient pressure to make the pressure uniform. The vibrator 49 at the position of excessive pressure will not be started. In this solution, the vibration amplitude and vibration pressure of multiple vibrators 49 can also be adjusted individually, thereby improving the efficiency of substrate adjustment.

[0065] In the above scheme, when the vibrator 49 is adjusting the vibration, the multiple second pressure detectors 44 are directly connected to the second elastic telescopic tube 45 and are located between the corresponding two sets of guide arc surfaces 35, so they can detect the position in time and improve the adjustment effect. The smooth and rounded design of the rice-shaped particles 46 further improves the efficiency of substrate movement, so that the substrate can still be adjusted slightly even under the action of micro-clamping. It should be noted that if the pressure deviation is extremely large, manual intervention is still required, and the multiple vibrators 49 can only be adjusted slightly.

[0066] In the above scheme, the flexible tube base 34 is made entirely of flexible material, which can reduce the occurrence of friction damage to the bottom of the substrate. The elastic support 48 provides basic elastic support, allowing the convex panel 50 and the guide arc surface 35 to abut against the bottom of the substrate for a long time, improving the arching efficiency. In this scheme, if cutting stress occurs at the cutting point after multiple cuttings of the substrate, multiple vibrators 49 can also be activated to vibrate the substrate, eliminate the stress generated by cutting, and improve the cutting effect.

[0067] Example 4:

[0068] A high-strength, fully open stainless steel mesh forming device, based on Embodiment 1 or 2, is further illustrated in the attached document. Figure 6 Appendix Figure 7 and attached Figure 8 An upwardly inclined heating seat 31 is connected between two adjacent support seats 36. Multiple jet heads 39 are provided on the upper surface of each heating seat 31. A miniature air pump 32 is provided on the end face of the counter 13 below the heating seat 31. The air supply end of the miniature air pump 32 is connected to the bottom of the heating seat 31 through a hose. An electric heating mesh plate 40 is also provided inside the heating seat 31.

[0069] Before cutting the substrate, the micro air pump 32 can inject gas into the heating base 31 through a hose. After the injected gas enters the heating base 31, the heating base 31 can then spray the gas appropriately onto the bottom of the substrate through the jet nozzle 39. This improves the gas flow efficiency outside the substrate and also has a certain dust removal effect. Before cutting, the electric heating mesh plate 40 can also heat the gas, so that the high-heat gas can be sprayed onto the bottom of the substrate, thereby preheating the substrate and making it less prone to cracking and deformation during cutting, further improving the cutting accuracy.

[0070] Furthermore, a vacuum cleaner seat 15 is provided on the end face of the counter 13 between multiple heating seats 31. The top of the vacuum cleaner seat 15 is mesh-like, and a fan assembly 38 is provided inside the vacuum cleaner seat 15. The fan assembly 38 includes a motor and a fan wheel, which are existing technologies and will not be elaborated on in this solution. A purifier 37 is fixedly installed on one side of the bottom of the vacuum cleaner seat 15. The air inlet of the purifier 37 is connected to the bottom of the vacuum cleaner seat 15 via a flexible hose. During the cutting of the substrate, the multiple heating seats 31 continuously spray gas, and then the fan assembly 38 will start working. The fan assembly 38 will suck the gas on the substrate into the vacuum cleaner seat 15, and then the purifier 37 will purify the harmful gases generated during the cutting of the substrate, so that when the staff opens the cabinet door 12 after the substrate is processed, the harmful gases will not cause excessive harm to the human body. The addition of the heating seats 31 can further improve the gas circulation efficiency outside the substrate and improve the purification effect. In this solution, the purifier 37 is existing technology and will not be elaborated on in this solution.

[0071] In the above embodiments, it should be noted that the multiple first push cylinders 19, second push cylinders 21, third push cylinders 61, etc., are all existing technologies. Electric push cylinders, pneumatic push cylinders, multi-stroke push cylinders, etc. can be selected, as long as they can complete the corresponding action commands and effects. This solution does not impose too many restrictions. Similarly, the first pressure detector 42, second pressure detector 44, distance detector 25, etc., only need to be able to complete the corresponding detection purpose. The specific internal detection principle, etc., are not subject to too many restrictions in this solution.

[0072] Example 5:

[0073] A high-strength, fully open stainless steel mesh forming process is described below:

[0074] Step 1: Substrate Selection

[0075] Stainless steel material between 10-30um is selected as the substrate to ensure the high strength and durability of the screen. After the substrate is selected, chemical polishing or mechanical grinding is used to improve the overall surface roughness and enhance the bonding force when it is combined with nylon mesh and other materials.

[0076] For stainless steel materials, 310S stainless steel, 304, 316, etc., which have good high temperature resistance can be selected. Annealing treatment is required to remove internal residual stress and avoid cracks and damage during subsequent cutting.

[0077] Step Two: Pattern Design

[0078] Digital pattern design tools are used to design fully open patterns according to requirements. These tools need to be able to directly interface with laser engraving equipment to reduce errors in the pattern conversion process. During the design process, simulation software is used to perform simulation processing, make predictions in advance, and assist in modifications.

[0079] Step 3: Composite lamination

[0080] Stainless steel sheets and nylon mesh are bonded together using a combination of hot and cold pressing. First, hot pressing at an appropriate temperature ensures the adhesive materials fully fuse. Then, cold pressing is performed to set the shape, improving the bond's strength and stability, resulting in a mesh screen. During the lamination process, the uniformity of the adhesive and the presence of air bubbles can be monitored to prevent batch lamination quality issues.

[0081] Step 4: Laser engraving:

[0082] The equipment designed in this invention, after uniformly stretching and fixing the screen to ensure force is applied in all directions, uses a femtosecond laser to melt through the screen where holes are needed, forming the screen pattern. In this step, the width and depth of the slots can be adjusted by controlling the laser's power and frequency, adapting to the processing of stainless steel plates of different thicknesses and materials. Furthermore, because composite lamination is used before laser grooving, and the stainless steel plate is already stretched during grooving, the image after grooving is less prone to deformation or distortion. In contrast, existing methods that grooving before lamination result in patterns easily deforming under tension.

[0083] Step 5: Screen Printing Inspection

[0084] In addition to testing the overall microstructure and surface quality of the screen using various testing devices, it is also necessary to test the screen's air permeability, light transmittance, and other properties to ensure that the screen can be used normally.
