Description

Technical Field

[0001] This application relates to the field of screen printing preparation, and in particular to a dry degreasing device for solar steel wire screens. Background Technology

[0002] Degreasing of solar screen printing plates is a core pretreatment process in the photovoltaic industry's screen printing plate-making process, after the screen is stretched and before the photosensitive emulsion is coated. Through the combined action of chemical and physical methods, various greases, oil stains, and impurities on the screen surface are thoroughly removed, which is a key step in ensuring the accuracy of solar screen printing plates, printing yield, and service life.

[0003] Currently, the degreasing process in the existing solar screen manufacturing process typically uses a wet degreasing method. The specific process is as follows: the screen is rinsed with water, ghosting paste is applied to both sides of the screen to remove the oxide layer on the surface of the steel wire, then it is rinsed clean with water again, then both sides are scrubbed with a sponge dipped in degreasing solution, left to stand for 3 minutes, rinsed with water, and finally dried.

[0004] However, the existing wet degreasing process is cumbersome, requiring multiple rinsing, coating, and wiping operations, resulting in low operational efficiency, and therefore needs to be improved. Summary of the Invention

[0005] In order to improve the problem of the cumbersome process and low operating efficiency of the existing wet degreasing process, this application provides a dry degreasing device for solar steel wire mesh.

[0006] The dry degreasing equipment for solar-powered steel wire mesh provided in this application adopts the following technical solution: A dry degreasing device for solar-powered steel wire mesh includes a sealed box, a door, a plasma generator, and a mesh support mechanism. The sealed box has an opening on one side, and the door is hinged to the outer wall of the sealed box to close the opening. The plasma generator is located inside the sealed box and is used to create a plasma environment within the sealed box. The mesh support mechanism is located inside the sealed box and is used to place the mesh vertically within the sealed box, ensuring that both sides of the mesh are fully exposed to the plasma environment.

[0007] By adopting the above technical solution, once the chamber door is closed, the sealed box forms a closed working chamber. The plasma generator is activated, ionizing the gas inside the chamber into high-energy plasma. The screen is placed vertically by a supporting mechanism, with both its front and back sides exposed to the plasma atmosphere without obstruction. The high-energy particles in the plasma efficiently remove grease and impurities from the screen surface through physical bombardment and chemical reactions. The entire process requires no chemical reagents or pure water rinsing, simplifying the operation and eliminating wastewater discharge at the source.

[0008] Optionally, the screen mounting mechanism includes a plurality of locking blocks, which are arranged sequentially at intervals along the length of the opening of the sealed box and along the depth of the sealed box. The locking blocks are provided at both the top and bottom of the sealed box, and the locking blocks at the top and bottom of the sealed box are arranged opposite to each other.

[0009] By adopting the above technical solution, the opposing card blocks together form a slot, and the top and bottom edges of the screen can be inserted into the corresponding card blocks respectively, achieving a stable vertical fixation. Multiple sets of card blocks can hold multiple screens simultaneously, effectively increasing the processing capacity per batch and ensuring that both sides of the screen are fully exposed.

[0010] Optionally, the card block includes a mounting plate and a movable plate, the movable plate being slidably connected to the mounting plate, and the sealing box being provided with a movable component, which is connected to the movable plate and is used to drive the movable plate to move toward or away from the mounting plate.

[0011] By adopting the above technical solution, the moving component can actively adjust the distance between the mounting plate and the moving plate, thereby making the width of the slot formed by the card block adjustable, which can flexibly adapt to screens of different thicknesses and improve the versatility of the equipment.

[0012] Optionally, the moving component includes a moving gear and a moving rack. The moving gear is rotatably connected to the sealing box, and the moving rack is arranged along the length direction of the opening of the sealing box and slidably connected to the sealing box. The moving gear rotates to drive the moving rack to translate. The moving plate is connected to the moving rack.

[0013] By adopting the above technical solution, when a moving gear rotates, it can drive the moving rack meshing with it to translate along the length direction, thereby driving all the moving plates connected to the moving rack to move synchronously. This achieves synchronous and precise adjustment of the width of multiple locking slots, simplifies operation, and ensures consistency.

[0014] Optionally, a positioning plate is slidably connected to the sealing box, the positioning plate is arranged along the length direction of the opening of the sealing box, the mounting plate is disposed on the positioning plate, the moving rack is slidably connected to the positioning plate, the positioning plate is provided with a connecting component, the connecting component can be connected to the moving rack, and is used to fix the positioning plate and the moving rack, the sealing box is provided with an adjusting component, the adjusting component is connected to two moving gears, and is used to drive the two moving gears to rotate in opposite directions, and the sealing box is provided with a rotating component, the rotating component is connected to a locking block, and is used to drive the locking block to tilt.

[0015] By adopting the above technical solution, when the slot width needs to be adjusted, the connecting assembly separates, and the rotation of the moving gear only drives the moving rack to translate relative to the positioning plate. When it is necessary to accommodate larger screens, especially those in the height direction, the connecting assembly locks the positioning plate and the moving rack, and the adjusting assembly drives the upper and lower moving gears to rotate in opposite directions, causing the upper and lower positioning plates and the locking blocks to translate in opposite directions. At the same time, the rotating assembly causes the upper and lower locking blocks to tilt in opposite directions. In this way, the openings of the upper and lower locking blocks are still opposite, but the whole structure forms an oblique insertion space, cleverly accommodating larger screens within the limited cavity height, significantly expanding the processing capacity of the equipment.

[0016] Optionally, the connecting assembly includes a connecting cylinder and a connecting rack. The connecting rack is arranged along the length of the positioning plate, and the connecting cylinder is disposed on the positioning plate. The output end of the connecting cylinder is fixed to the connecting rack and is used to drive the connecting rack to move up and down. The connecting rack can mesh with the moving rack.

[0017] By adopting the above technical solution, when the connecting cylinder extends, the connecting rack moves downward and engages with the moving rack. Since the connecting rack itself is restricted from lateral movement by the positioning plate, the moving rack and the positioning plate are locked together. When the connecting cylinder retracts, the connecting rack moves upward and disengages, allowing the moving rack to slide freely relative to the positioning plate. This structure is compact, has reliable locking, and enables rapid switching between two working modes.

[0018] Optionally, the rotating assembly includes a rotating rack and several rotating gears. The rotating rack is fixed on the sealing box and arranged along the length of the positioning plate. The several rotating gears correspond one-to-one with the mounting plate. The rotating gears are fixed to the mounting plate and mesh with the rotating rack.

[0019] By adopting the above technical solution, when the positioning plate moves horizontally under the drive of the adjusting component, the mounting plate moves horizontally accordingly, causing the rotating gear to roll on the fixed rotating rack, thereby causing the rotating gear to rotate, which in turn causes the entire locking block, i.e., the mounting plate and the moving plate, to deflect. Since the upper and lower positioning plates move in opposite directions, the upper and lower locking blocks also deflect in opposite directions, ensuring that the screen can still be correctly positioned in the oblique insertion state.

[0020] Optionally, the movable plate is provided with a slider, the slider is fitted with a sliding sleeve, the slider is connected to the inner wall of the sliding sleeve by a spring, the mounting plate is provided with a sliding groove, the sliding sleeve is inserted into the sliding groove and can move in the sliding groove, and the movable plate is slidably connected to the movable rack.

[0021] By adopting the above technical solution, the moving plate and the mounting plate are connected by a sliding sleeve and a slider. When the locking block tilts, this structure ensures that the moving plate can rotate with the mounting plate. At the same time, the elastic force provided by the spring allows the depth of the locking slot to have a certain self-adjusting capability, which can better fit the edge of the screen and absorb the slight displacement deviation that may be caused by tilting, protecting the screen from rigid compression damage.

[0022] Optionally, the adjustment assembly includes a rotary motor and an adjustment motor. The rotary motor is mounted on the sealed box, and its output end is coaxially fixed to one of the moving gears via a rotating rod. The adjustment motor is mounted on the sealed box, and its output end is coaxially fixed to the other moving gear via an adjustment rod.

[0023] By adopting the above technical solution, the two moving gears are driven by independent motors, enabling them to rotate in the same or opposite directions. When it is necessary to adjust the slot width of the clamping block, the two motors rotate in the same direction and at the same speed, and the upper and lower moving racks move in the same direction, resulting in a symmetrical change in the slot width. When it is necessary to switch to the oblique insertion mode for large-size screen printing plates, the two motors rotate in opposite directions, driving the upper and lower positioning plates to move in opposite directions, thus achieving the staggering of the upper and lower clamping blocks for oblique insertion of the screen printing plate.

[0024] Optionally, the sealed box is provided with a metal frame, and a baffle is magnetically attached to the metal frame, the baffle being able to abut against the side wall of the screen.

[0025] By adopting the above technical solution, the magnetic baffle assembly can be quickly assembled and disassembled according to the screen size and the area to be protected. The baffle can constrain the plasma discharge area and prevent plasma from affecting areas on the screen that do not need to be cleaned, thus achieving selective cleaning and further improving process accuracy.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. The plasma dry degreasing process completely eliminates the use of chemical agents and pure water, eliminating the generation of wastewater and hazardous waste from the source, realizing green and environmentally friendly manufacturing, while simplifying the process and improving production efficiency. 2. The magnetic baffle assembly can flexibly constrain the plasma discharge area, enabling selective cleaning of specific areas of the screen, avoiding unnecessary processing, and improving process accuracy and product quality.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a dry degreasing device for solar-powered steel wire mesh. (Refer to...) Figure 1 and Figure 2 The solar-powered steel wire mesh dry degreasing equipment includes a sealed box 1 with an opening on the front. One side of a door 11 is hinged to the outer wall of the sealed box 1 to close the opening; an observation window can be installed on the door 11. A plasma generator 2 is installed inside the sealed box 1. Reference Figure 1 and Figure 2 In this application, the plasma generating device 2 consists of a radio frequency power supply and an electrode plate, used to excite and maintain the plasma environment within the sealed chamber 1. The screen mounting mechanism 3 is located at the bottom and top of the inner wall of the sealed chamber 1, used to fix the screen in a vertical position perpendicular to the bottom surface of the chamber, ensuring that both sides of the screen are exposed to the plasma without obstruction.

[0031] Reference Figure 2 and Figure 3 The screen mounting mechanism 3 includes multiple sets of locking blocks 31. These locking blocks 31 are arranged sequentially at intervals along the length of the opening of the sealed box 1, i.e., in the left-right direction. Each locking block 31 is arranged along the depth of the sealed box 1, forming a front-to-back extending slot. The top and bottom inner walls of the sealed box 1 are also provided with the same arrangement of locking blocks 31, with the upper and lower locking blocks 31 facing each other.

[0032] Reference Figure 3 and Figure 4The locking block 31 specifically includes a mounting plate 311 and a movable plate 312. The mounting plate 311 is mounted on the positioning plate 4. The movable plate 312 is slidably connected to the mounting plate 311. The sealing box 1 is provided with a movable component 5, which can drive the movable plate 312 to move closer to or further away from the mounting plate 311, thereby changing the width of the locking slot. The movable component 5 includes a movable gear 51 and a long, narrow movable rack 52. The movable gear 51 is rotatably connected to the inner wall of the sealing box 1, and the movable rack 52 is arranged along the length of the opening of the sealing box 1 and meshes with the movable gear 51. The movable rack 52 is slidably connected to the sealing box 1, and a sliding rod is fixed on the movable rack 52. A sliding groove is provided on the movable plate 312, one end of the sliding rod is inserted into the sliding groove and can move in the sliding groove, and the end of the sliding rod can rotate in the sliding groove. When the moving gear 51 rotates, it drives the moving rack 52 to move left and right, thereby causing all the moving plates 312 connected to it to move synchronously.

[0033] Reference Figure 2 and Figure 3 To further accommodate screens of different heights, i.e., screens with different vertical dimensions, a positioning plate 4 is slidably connected to the top and bottom of the sealed box 1. Both the top and bottom positioning plates 4 are arranged in a left-right direction. A mounting plate 311 is mounted on the positioning plates 4. A movable rack 52 is directly slidably connected to the positioning plates 4. A connecting assembly 7 is provided on the positioning plates 4 for selectively locking the movable rack 52 to the positioning plates 4. The connecting assembly 7 includes a connecting cylinder 71 and a connecting rack 72. The connecting rack 72 is arranged in a left-right direction, and the connecting cylinder 71 is vertically fixed to the positioning plates 4, with its piston rod end connected to the connecting rack 72, driving the connecting rack 72 to move up and down. When the connecting rack 72 moves out of the positioning plate 4, it engages with the movable rack 52. Since the connecting rack 72 cannot move left or right, it locks the movable rack 52 and the positioning plate 4 together.

[0034] Reference Figure 3 and Figure 4 The sealed housing 1 is equipped with an adjustment assembly 6 and a rotation assembly 8. The adjustment assembly 6 includes a rotation motor 61 and an adjustment motor 63. The rotation motor 61 is mounted on the side wall of the sealed housing 1, and its output shaft is coaxially fixed to the moving gear 51 located at the top via a rotation rod 62. The adjustment motor 63 is mounted on the side wall of the sealed housing 1, and its output shaft is coaxially fixed to the moving gear 51 located at the bottom via an adjustment rod 64. The rotation assembly 8 includes a rotating rack 81 fixed to the inner side wall of the sealed housing 1, and a plurality of rotating gears 82 respectively fixed to the ends of each mounting plate 311. The rotating gears 82 mesh with the rotating rack 81. The rotating gears 82 are rotatably connected to the positioning plate 4, and the rotating gears 82 are fixed to the mounting plate 311 via a rod arranged radially thereon, so that the mounting plate 311 can deflect on the positioning plate 4.

[0035] When the slot width needs adjustment, the connecting assembly 7 separates, and the rotation of the moving gear 51 only drives the moving rack 52 to translate relative to the positioning plate 4. When it is necessary to accommodate a larger screen, especially in the height direction, the connecting rack 72 extends out of the positioning plate 4 and is locked to the inner box of the moving rack 52, thus locking the positioning plate 4 and the moving rack 52. The adjusting assembly 6 drives the upper and lower moving gears 51 to rotate in opposite directions, causing the upper and lower positioning plates 4 and the locking blocks 31 to translate in opposite directions. At the same time, the rotating assembly 8 tilts the upper and lower locking blocks 31 in opposite directions. In this way, the openings of the upper and lower locking blocks 31 are still opposite, but the whole form an oblique insertion space, cleverly accommodating a larger screen within the limited cavity height, significantly expanding the processing capacity of the equipment.

[0036] Reference Figure 3 and Figure 4 The two moving gears 51 are driven by independent motors, allowing them to rotate in the same or opposite directions. When the slot width of the locking block 31 needs to be adjusted, the two motors rotate in the same direction and at the same speed, and the upper and lower moving racks 52 move in the same direction, resulting in a symmetrical change in slot width. When switching to the oblique insertion mode for large-size screen printing plates, the two motors rotate in opposite directions, driving the upper and lower positioning plates 4 to move in opposite directions, thus offsetting the upper and lower locking blocks 31 to allow for oblique insertion of the screen printing plate.

[0037] Reference Figure 2 and Figure 5 The movable plate 312 is equipped with a slider 314, and a sliding sleeve 315 is fitted onto the slider 314. The slider 314 is connected to the inner wall of the sliding sleeve 315 by a spring 316. The mounting plate 311 is equipped with a sliding groove 313, and the sliding sleeve 315 is inserted into the sliding groove 313 and can move along the sliding groove 313. The bottom of the movable plate 312 is also slidably connected to the movable rack 52.

[0038] The movable plate 312 and the mounting plate 311 are connected by a sliding sleeve 315 and a slider 314. When the locking block 31 tilts, this structure ensures that the movable plate 312 can rotate with the mounting plate 311. At the same time, the elastic force provided by the spring 316 gives the slot depth a certain degree of self-adjustment capability, which can better fit the edge of the screen and absorb the slight displacement deviation that may be caused by tilting, protecting the screen from rigid compression damage.

[0039] Reference Figure 2 In addition, a metal frame 9 is fixed to the inner wall of the sealed box 1, and multiple baffles are magnetically attached to the metal frame 9. The shape and position of the baffles are designed according to the screen frame edge or the area to be protected, and can abut against the side wall of the screen, thereby blocking the plasma from bombarding the specific area.

[0040] The implementation principle of the dry degreasing device for solar steel wire mesh in this application embodiment is as follows: Based on the thickness of the mesh to be treated, the rotating motor 61 and the adjusting motor 63 are started to rotate in the same direction. At this time, the connecting cylinder 71 is in the retracted state, and the connecting rack 72 is disengaged from the moving rack 52. The moving gear 51 drives the moving rack 52 to translate relative to the positioning plate 4, thereby moving the moving plate 312 and adjusting the slot width to a suitable size. Multiple meshes are inserted into the corresponding upper and lower slots 31. The chamber door 11 is closed, and the plasma generator 2 is started, filling the sealed chamber 1 with high-energy plasma to simultaneously perform dry degreasing on both sides of the mesh.

[0041] When the screen printing plate is too tall and vertical insertion would interfere with the upper and lower locking blocks 31, the connecting cylinder 71 first drives the connecting rack 72 to move downwards, engaging with the moving rack 52 and locking the moving rack 52 to the positioning plate 4. Then, the rotating motor 61 and the adjusting motor 63 are started to rotate in opposite directions. The moving gears 51 at the top and bottom rotate in opposite directions, driving the upper and lower positioning plates 4 to move in opposite directions, for example, the top positioning plate 4 to the left and the bottom positioning plate 4 to the right. At the same time, the positioning plates 4 drive the mounting plate 311 to move, and the rotating gear 82 on the mounting plate 311 rolls on the fixed rotating rack 81, driving the entire locking block 31 to rotate. Since the upper and lower positioning plates 4 move in opposite directions, the upper and lower locking blocks 31 also rotate in opposite directions, for example, the top locking block 31 tilts clockwise and the bottom locking block 31 tilts counterclockwise, so that the opening slots of the upper and lower locking blocks 31 are still opposite. At this time, the screen printing plate with a larger height can be inserted into the opening of the upper and lower locking blocks 31 at an angle. The structure of spring 316 and sliding sleeve 315 can adaptively compensate for minor deviations in insertion angle and position.

[0042] When processing screens that require edge protection, according to process requirements, magnetic baffles are attached to the corresponding positions on the metal frame 9, so that the baffles adhere to the area of ​​the screen that needs protection, thereby constraining the plasma discharge area and achieving precise degreasing.

[0043] 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.
