Description

Technical Field

[0001] The invention relates to the technical field of PCB circuit board development and etching, and in particular to a spray disc for plate development processing. Background Art

[0002] PCB board developer spray tray refers to the equipment or device used to spray developer evenly and accurately onto the surface of photosensitive materials to remove the unexposed parts during the PCB manufacturing process. It is usually equipped in the developer to ensure the efficiency and accuracy of the development process by controlling the developer temperature, spray pressure and other parameters, so that the copper foil on the circuit board is accurately exposed according to the design pattern, laying the foundation for subsequent etching and other process steps.

[0003] In the development process of PCB boards, the spray plate plays a vital role. It is responsible for spraying the developer evenly and accurately onto the surface of the PCB board to be processed. However, with the long-term use of the spray plate, some stains often remain inside it, and the nozzle is easily blocked by impurities in the developer solution. Since the spray plate is designed with a tight pipeline structure, this not only increases the difficulty of disassembly and assembly operations, but also greatly reduces the convenience of use.

[0004] For example, the Chinese utility model patent (application number: 202223518619.0) discloses a "developer spray disc that is easy to maintain". Its specification discloses: The difference between the two structural forms of developer spray discs is whether the liquid inlet pipe is connected to the spray disc strip through the spray disc frame, but both can realize the delivery of developer from the liquid inlet pipe to the spray disc strip and spraying by the nozzle. The above two structural forms of developer spray discs have the following problems in actual production: 1. The cross-section of the spray disc is rectangular, and a square channel is formed inside. Foreign matter is blocked and hidden at right angles. It is difficult to clean when the internal dry film residue is blocked, which is not conducive to clearing the channel; the spray disc frame and the liquid inlet pipe are usually connected by the same square channel structure, and there is the same problem of blockage at right angles and foreign matter being difficult to clean; 2. The channel formed by the spray disc strip or the spray disc frame is not provided with a dredging port, which makes it inconvenient to clean the dirt and foreign matter in the channel when the channel is blocked. The above two shortcomings are not conducive to the maintenance of the developer spray plate in actual production. The channel is easy to be blocked and difficult to clean, and the cleaning and maintenance effect is difficult to be thorough, resulting in quality defects such as open circuits, gaps, residual copper, and short circuits in circuit board products, affecting the yield of circuit board products. The above patents can prove the defects of the existing technology.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the scheme of this application:

[0022] 1. In order to solve the problem that some stains often remain inside the spray disc after long-term use in the prior art, and the nozzle is also easily blocked by impurities in the developer solution, since the spray disc is designed with a tight pipeline structure, this not only increases the difficulty of disassembly and assembly, but also greatly reduces the convenience of use. By tilting the auxiliary cylinder with the nozzle, and the distance between the square tubes connected at both ends is continuously increased, the partition sleeved in the auxiliary cylinder is brought out, so that the nozzle installed in the shadow disc can be quickly disassembled and assembled in a tilted manner, which increases the convenience of cleaning the spray disc;

[0023] 2. During the tilting movement of the auxiliary tube, the side gears installed at both ends of the auxiliary tube mesh with the arc-shaped toothed plates on the surface of the frame plate. During the rotation process, the auxiliary tube rotates with the partition plate as the axis, so that the spray angle of the nozzle changes accordingly, thereby adjusting the angle of the nozzle structure that sprays the developer from the spray disc, thereby improving the uniformity of the developer spray;

[0024] 3. The distance between two adjacent auxiliary cylinders in the longitudinal distribution is gradually reduced during the tilting process, which squeezes the side airbags distributed in the two auxiliary cylinders so that the gas is squeezed and processed. During the reverse reset process, the distance between them is gradually expanded, and the side airbags restrict them, which will push the auxiliary cylinder to reset. The expansion of the side airbags will also generate suction to recover the developer on the workbench, so that the developer can be recycled and reused while assisting the reset;

[0025] 4. During the disassembly and assembly process, the auxiliary cylinder is driven to tilt continuously, so that the distance between the two square tubes is continuously expanded, and the partition is driven to slide in the auxiliary cylinder and finally disengage, so as to realize the tilting disassembly and assembly operation. During the angle adjustment process, due to the continuous tilting of the auxiliary cylinder, side gears are installed at both ends of the auxiliary cylinder to engage with the arc-shaped toothed plate on the surface of the frame plate. During the continuous tilting process, the auxiliary cylinder rotates with the square tube as the axis, and the spray angle of the nozzle is changed. During the recovery process, due to the continuous tilting of the two longitudinally distributed auxiliary cylinders, the distance between them is continuously reduced. At this time, the side airbags will be squeezed to shrink and exhaust, so as to provide power for rebound expansion, so that it can be flexibly switched between the disassembly and assembly structure, the angle adjustment structure and the extrusion structure to ensure the convenience of PCB board development processing;

[0026] 5 The position of the mesh plate is adjusted by the pressure of the developer entering the positioning tube, so that its cavity can be adjusted according to the pressure of the developer entering the positioning tube, thereby ensuring the stability of the developer introduction process.

[0045] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0046] As described in the background technology, with the long-term use of the spray plate, some stains often remain inside it, and the nozzle is also easily clogged by impurities in the developer solution. Since the spray plate is designed with a tight pipeline structure, this not only increases the difficulty of disassembly and assembly operations, but also greatly reduces the convenience of use.

[0047] In order to solve this technical problem, the present invention provides a spray plate for plate development processing, which is applied to the field of PCB circuit board development and etching technology.

[0048] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11A spray plate for plate developing processing comprises a frame plate 1, both sides of the frame plate 1 are fixedly connected with side boxes 2, a disassembly assembly 3 is fixedly connected between the two sides of the frame plate 1, an angle adjustment assembly 6 is arranged on the surface of the frame plate 1, the disassembly assembly 3 comprises a plurality of slide grooves 301 evenly distributed in a straight line on the surface of the frame plate 1, a plurality of sliders 302 are movably connected with the inner wall of the slide groove 301, a middle frame tube 303 is fixedly connected above the slider 302, both ends of the middle frame tube 303 are fixedly connected with semicircular groove plates 304, a circular convex plate 315 is sleeved between the inner walls of the semicircular groove plates 304, a square tube 305 is fixedly connected to the end of the circular convex plate 315 away from the semicircular groove plates 304, a through hole 310 is opened in the middle of the inner wall of the circular convex plate 315 and the square tube 305, and the square tube 305 is away from the circular convex plate 315. A partition 309 is fixedly connected to one end of the convex plate 315, and an auxiliary tube 307 is sleeved on the outer walls of two adjacent partitions 309. A nozzle 308 is fixedly connected to the middle of the outer wall of the auxiliary tube 307. Its slider 302 moves in the slide groove 301, driving the middle frame tube 303 to follow the movement. Since the middle frame tube 303 and the semicircular groove plate 304 are sleeved with each other, the angle between the square tubes 305 at both ends of the two distributed middle frame tubes 303 is gradually reduced, which drives the partition 309 connected to the square tube 305 to slide in the auxiliary tube 307. When the two partitions 309 in the auxiliary tube 307 are driven by the square tube 305 to detach from the auxiliary tube 307, the auxiliary tube 307 with the nozzle 308 can be taken out between the two partitions 309.

[0049] The spray plate for plate developing processing provided by the present invention is configured such that the auxiliary tube 307 with the nozzle 308 is tilted, and the distance between the square tubes 305 connected at both ends is continuously increased, so that the partition 309 sleeved in the auxiliary tube 307 is brought out, so that the nozzle 308 installed in the developing plate can be quickly disassembled and assembled in a tilted manner, thereby increasing the convenience of cleaning the spray plate.

[0050] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] Example 1, please refer to Figure 1 , Figure 7 and Fig.11A spray plate for plate developing processing, the two side boxes 2 have opposite surfaces that are straight and evenly distributed and fixedly connected with a plurality of side circular groove plates 306, the side circular groove plates 306 and the adjacent circular convex plates 315 are mutually sleeved, and the sleeved connection between the side circular groove plates 306 and the circular convex plates 315 enables it to have liquid conduction performance while also enabling it to change its angle.

[0054] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the rear ends of several sliders 302 in the frame plate 1 pass through the slide groove 301 and are fixedly connected to the double-toothed plate 313, and auxiliary gears 312 are movably connected on both sides of the double-toothed plate 313. The auxiliary gear 312 is meshed and connected with the side toothed plate 311 away from the double-toothed plate 313. Several sliders 302 on both sides pass through the corresponding slide grooves 301 and are fixed on the surfaces of adjacent side toothed plates 311. The rear ends of the double-toothed plates 313 are fixedly connected to the telescopic rod 314, and the other end of the telescopic rod 314 is fixedly installed on the inner wall of the frame plate 1. The double-toothed plate 313 is displaced by the telescopic rod 314, and then the auxiliary gear 312 meshed with it rotates accordingly, and the side toothed plate 311 meshed away from the double-toothed plate 313 follows the movement, but its movement direction is opposite to that of the double-toothed plate 313.

[0055] Example 3, the spray plate for plate development processing provided in Examples 1 and 2 is further optimized, specifically, Figure 1 , Figure 2 , Figure 4 , Fig. 9 and Fig.10 As shown, the angle adjustment component 6 includes side gears 603 fixedly mounted at both ends of the auxiliary cylinder 307, and a plurality of semi-arc tooth plates 602 are evenly distributed and fixedly connected in a straight line in the middle of the surface of the frame plate 1, and are located directly below the auxiliary cylinder 307. The semi-arc tooth plates 602 are meshed and connected with the side gears 603. A plurality of side arc tooth plates 601 are evenly distributed and fixedly connected in a straight line on both sides of the surface of the frame plate 1. The side arc tooth plates 601 are meshed and connected with the adjacent side gears 603. When the square tube 305 is driven by the middle frame cylinder 303 connected by the slider 302, its angle When the auxiliary cylinder 307 is tilted, the side gears 603 connected to the two ends of the auxiliary cylinder 307 in the middle are meshed with the semi-arc tooth plates 602 on the surface of the frame plate 1, and the side gears 603 connected to one end of the auxiliary cylinder 307 on both sides are meshed with the side arc tooth plates 601 on the surface of the frame plate 1. When the auxiliary cylinder 307 is offset from the center point, due to the meshing connection between the gears and the tooth plates, the auxiliary cylinder 307 is driven to rotate around the partition plate 309 connected to the square tube 305 as the axis, so that the nozzle 308 on the outer wall of the auxiliary cylinder 307 rotates accordingly.

[0056] During the tilting movement of the auxiliary cylinder 307, since the side gears 603 installed at both ends of the auxiliary cylinder 307 mesh with the arc-shaped tooth plates on the surface of the frame plate 1, the auxiliary cylinder 307 rotates with the partition plate 309 as the axis during the rotation, so that the spray angle of the nozzle 308 changes accordingly, thereby being able to adjust the angle of the nozzle 308 structure that sprays the developer from the spray disc, thereby improving the uniformity of the developer spraying.

[0057] Example 3, the spray plate for plate development processing provided in Examples 1 and 2 is further optimized, specifically, Figure 1 , Figure 2 and Figure 6 As shown, the extrusion assembly 7 includes a side airbag 704 movably installed between two longitudinally adjacent auxiliary cylinders 307, a connecting pipe 705 is fixedly connected between two transversely adjacent side airbags 704, and a check valve 706 is fixedly connected to the side of the side airbag 704. A positioning frame 703 is fixedly connected to one side of the side airbag 704, and the other end of the positioning frame 703 penetrates the side wall of the adjacent side box 2. A support tube 707 is fixedly connected to one side of the side airbag 704 on the other side. The auxiliary cylinder 307, which is rotated and tilted at its midpoint, is continuously tilted. During the process, the distance between two adjacent auxiliary cylinders 307 distributed longitudinally is gradually reduced, and the side airbags 704 therebetween are squeezed, so that the gas inside is discharged through the check valve 706. When the distance between two adjacent auxiliary cylinders 307 distributed longitudinally is gradually increased, the side airbags 704 also expand outward, synchronously pushing the auxiliary cylinder 307 to move, and then several side airbags 704 work synchronously in cooperation with the connecting tube 705 and the supporting tube 707, so that the drainage tube 701 attracts the developer remaining on the workbench into the side box 2.

[0058] By gradually reducing the distance between two adjacent auxiliary cylinders 307 longitudinally during the tilting process, the side airbags 704 distributed in the two auxiliary cylinders 307 are squeezed so that the gas is squeezed and processed. During the reverse resetting process, the distance between them is gradually expanded, and the side airbags 704 restrict them, which will push the auxiliary cylinder 307 to reset. The expansion of the side airbags 704 will also generate suction to recover the developer on the workbench, so that the developer can be recycled and reused while assisting the resetting.

[0059] Further, such as Figure 2 As shown, a liquid-blocking exhaust valve 702 is fixedly connected to the middle of the support tube 707, and the liquid-blocking exhaust valve 702 is fixedly installed on the side wall of the adjacent side box 2. A plurality of drainage tubes 701 are fixedly connected to one side of the side box 2 close to the support tube 707 and evenly distributed in a straight line. The liquid-blocking exhaust valve 702 prevents the developer from entering the side airbag 704 and affecting the expansion and contraction process of the side airbag 704.

[0060] Example 4, the spray plate for plate development processing provided in Example 1, 2 or 3 is further optimized, specifically, Figure 1 , Figure 3 and Figure 5 As shown, the voltage stabilizing component 8 includes a plurality of positioning tubes 801 which are evenly distributed and fixedly installed on the inner wall of another side box 2 in a straight line, and one end of the positioning tube 801 passes through the adjacent side box 2, and a plurality of conical springs 805 are evenly distributed and fixedly connected to the inner wall of the positioning tube 801, and a positioning plate 804 is fixedly connected to the other end of the plurality of conical springs 805, and a plurality of auxiliary rods 806 are evenly distributed and fixedly connected to the end of the positioning plate 804 away from the conical spring 805. The liquid medicine is introduced into the positioning tube 801 by the water inlet pipe 802. When the pressure of the developer gradually increases, the mesh plate 807 is pushed toward one end of the water outlet pipe 803, and the conical spring 805 is squeezed to shrink, so that its cavity becomes larger and the pressure is released, otherwise the cavity is reduced and the pressure is increased, so that the developer is stably transported to each group of auxiliary tubes 307.

[0061] The position of the mesh plate 807 is adjusted by the pressure of the developer entering the positioning tube 801, so that its cavity can be adjusted according to the pressure of the developer entering the positioning tube 801, thereby ensuring the stability of the developer introduction process.

[0062] Further, such as Figure 5 As shown, a mesh plate 807 is fixedly installed at the other end of several auxiliary rods 806. The outer wall of the mesh plate 807 is movably connected to the inner wall of the positioning tube 801. The mesh plate 807 contacts the introduced developer and can filter the drug solution by sensing the pressure during the developer introduction process.

[0063] Further, such as Figure 5 As shown, a water outlet pipe 803 is fixedly connected to the middle of the positioning plate 804, one end of the water outlet pipe 803 passes through the positioning pipe 801 and is fixedly connected to the inner wall of the side box 2, and one end of the water outlet pipe 803 is placed inside the side box 2, and the end of the positioning pipe 801 away from the side box 2 is fixedly connected to the water inlet pipe 802, and the developer can be introduced into the side box 2 through the cooperation between the water inlet pipe 802 and the water outlet pipe 803.

[0064] Further, such as Figure 1 As shown, two side panels 4 are symmetrically and evenly distributed and fixedly connected to one side of the rear end of the side box 2. Mounting holes 5 are opened on the surface of the side panels 4. The mounting holes 5 of the side panels 4 cooperate with bolts to install the entire structure at the desired position.

[0065] The use process of the spray plate for plate development processing provided by the present invention is as follows:

[0066] Working principle: The staff uses the mounting holes 5 in the side panel 4 to cooperate with the bolts to install the whole structure on the PCB board developing equipment;

[0067] Disassembly and assembly operation: place the auxiliary cylinder 307 between the two partitions 309, then start the telescopic rod 314 to drive the double tooth plate 313 to move upward along the slide groove 301, and under the drive of the auxiliary gear 312, the side tooth plates 311 on both sides move downward along the slide groove 301, and then the slider 302 drives the corresponding middle frame cylinder 303 to move. Since the semicircular groove plates 304 at both ends of the middle frame cylinder 303 are hingedly connected to the circular convex plates 315 connected to the square tube 305, the displacement of the frame cylinder 303 will drive the angle between the square tube and the slide groove 301 to gradually expand, and push the partition 309 into the auxiliary cylinder 307, and the side circular groove plates 306 on both sides are also hingedly connected to the circular convex plates 315 at the junction, so that the auxiliary cylinder 307 with the nozzle 308 can be installed in the frame plate 1;

[0068] Liquid guiding: Connected with the water inlet pipe 802 through the pipeline, the developer then flows into the fixed pipe along the pipeline and the water inlet pipe 802. When the pressure of the developer gradually increases, the mesh plate 807 is pushed closer to one end of the water outlet pipe 803, and the conical spring 805 is squeezed to shrink, so that the cavity becomes larger and the pressure is released. On the contrary, the cavity is reduced and the pressure is increased, so that the developer is guided into the adjacent side box 2.

[0069] Spraying: Since the through hole 310 structure is provided between the side circular groove plate 306, the circular convex plate 315, the square tube 305 and the semicircular groove plate 304, the developer enters the side box 2 and passes through the mutually connected side circular groove plate 306, the circular convex plate 315, the square tube 305 and the semicircular groove plate 304, so that the liquid medicine enters the auxiliary tube 307 between the two partitions 309, and then the liquid medicine is pushed by the pressure of the liquid medicine and sprayed out from the nozzle 308, so that the developer is initially sprayed;

[0070] Steering: While spraying the liquid medicine, the telescopic rod 314 is started to drive the double tooth plate 313 to move downward along the slide groove 301, and under the drive of the auxiliary gear 312, the side tooth plates 311 on both sides move upward along the slide groove 301, and then the slider 302 drives the corresponding middle frame tube 303 to move. Since the semicircular groove plates 304 at both ends of the middle frame tube 303 and the round convex plates 315 connected to the square tube 305 are hinged, the displacement of the frame tube 303 will drive the angle between the square tube and the slide groove 301 to gradually decrease, and then the angle of the auxiliary tube 307 will tilt, and the auxiliary tube 307 located in the middle will be tilted. The side gears 603 connected to the two ends of the cylinder 307 mesh with the semi-arc toothed plate 602 on the surface of the frame plate 1, and the side gears 603 connected to one end of the auxiliary cylinder 307 located on both sides mesh with the side arc toothed plate 601 on the surface of the frame plate 1. When the auxiliary cylinder 307 is offset from the center point, the meshing connection between the gear and the toothed plate drives the auxiliary cylinder 307 to rotate with the partition 309 connected to the square tube 305 as the axis, so that the nozzle 308 on the outer wall of the auxiliary cylinder 307 rotates accordingly, thereby realizing the angle adjustment during the spraying process to ensure the uniformity of the liquid spraying.

[0071] Recovery: Since the semicircular groove plates 304 at both ends of the middle frame tube 303 are hingedly connected to the circular convex plates 315 connected to the square tube 305, the displacement of the frame tube 303 will drive the angle between the square tube and the slide groove 301 to gradually decrease, and then the angle of the auxiliary tube 307 will be tilted. The auxiliary tube 307 rotates and tilts at the midpoint. During the continuous tilting process, the distance between the two adjacent auxiliary tubes 307 in the longitudinal distribution gradually decreases, and the side airbags 704 therebetween are squeezed, so that the gas inside is discharged by the check valve 706. When the distance between the two adjacent auxiliary tubes 307 in the longitudinal distribution gradually increases, the side airbags 704 also expand outward, synchronously pushing the auxiliary tube 307 to move, and then several side airbags 704 work synchronously in cooperation with the connecting tube 705 and the supporting tube 707, and the drainage tube 701 attracts the developer remaining on the workbench into the adjacent side box 2 for recovery operation.
