Description

Technical Field

[0001] This invention relates to the field of screen cleaning technology, and in particular to a dual-spray automatic cleaning and drying machine for cleaning screens. Background Technology

[0002] In today's electronics manufacturing industry, printed circuit boards play a crucial role. They are key tooling for achieving precise soldering of electronic components. After use, solder paste easily remains inside the tiny apertures of the stencil. Existing conventional spray rinsing technology has many limitations when dealing with such protruding stencils with tiny apertures and residual solder paste. Due to its own characteristics, the spray water flow is difficult to accurately and effectively penetrate into the apertures when impacting the stencil surface, resulting in insufficient rinsing of the solder paste.

[0003] In addition, existing cleaning equipment often focuses on cleaning the surface of large-area stencils, neglecting the critical area inside the apertures that is prone to dirt residue. This not only leads to incomplete stencil cleaning, affecting the quality of subsequent printing, such as uneven solder paste printing and poor soldering, reducing the yield of electronic products, but also the long-term residual solder paste can corrode the stencil, shorten its service life, greatly increase the production and maintenance costs of electronic manufacturing companies, and seriously restrict the improvement of production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-spray automatic cleaning and drying machine for cleaning mesh plates, which solves the problem of low cleaning efficiency in existing cleaning equipment in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-spray automatic cleaning and drying machine for cleaning mesh plates, comprising a cleaning tank and a dryer, wherein a movable component is provided at the top of the interior of the cleaning tank, and a spray component and a high-pressure rinsing component are installed below the movable component. The spray component includes a guide frame mounted on the movable component, and the high-pressure rinsing component includes a piston cylinder movably disposed inside the guide frame. The spray component also includes a sprayer installed outside the piston cylinder, and a metal hose is connected to the sprayer. The metal hose extends to the outside of the cleaning tank and is connected to a cleaning water tank and its cleaning pump. The piston cylinder has a piston chamber inside, and a first spring is fixedly installed on the upper part of the piston chamber. A piston plate is installed below the first spring and is in contact with the inner wall of the piston cylinder. The lower part of the piston cylinder is connected to a metal hose through a one-way liquid inlet valve. The high-pressure flushing assembly also includes a drive mechanism installed below the spray assembly. The drive mechanism is used to drive the piston cylinder to move downward and fit against the top of the mesh plate. The high-pressure flushing assembly also includes a valve plate rotatably installed inside the lower part of the piston cylinder. The top of the valve plate has a first liquid outlet evenly distributed, and the lower part of the piston cylinder has a second liquid outlet evenly distributed above the valve plate. The lower part of the piston cylinder also has a drive mechanism extending to the bottom of the piston cylinder. The drive mechanism is used to drive the valve plate to rotate when the piston cylinder contacts the mesh plate, so that the first liquid outlet on the valve plate corresponds to the second liquid outlet.

[0006] Furthermore, a conveyor belt is provided at the bottom of the interior of the cleaning tank, and the conveyor belt extends into the interior of the dryer. The conveyor belt is used to support the mesh plate and transport the mesh plate.

[0007] Furthermore, the sprayer has an inner cavity, and spray holes are evenly distributed in the lower part of the sprayer. The spray holes away from the center of the sprayer have a greater tilt angle than the spray holes near the center of the sprayer. One end of the metal hose extends into the inner cavity, and the cleaning liquid is delivered into the inner cavity by an external cleaning pump, forming a high-pressure water flow impact at the spray holes.

[0008] Furthermore, the moving component includes a longitudinal guide rail fixedly installed on the inner wall of the cleaning tank and a transverse guide rail slidably installed on the longitudinal guide rail. The moving component also includes a first motor installed on the top of the transverse guide rail and a moving mechanism and a transmission mechanism installed inside the transverse guide rail.

[0009] Furthermore, the moving mechanism is provided in two sets, located above and below the transverse guide rail respectively. The moving mechanism includes a synchronous belt, and driving wheels and driven wheels arranged on both sides inside the synchronous belt. The driving wheels and driven wheels are rotatably arranged inside the transverse guide rail, and the two sets of driving wheels are connected by a transmission mechanism. The transmission mechanism is a transmission structure composed of a transmission shaft and a gear set. The output end of the first motor extends into the interior of the transverse guide rail and is fixedly connected to one of the sets of driving wheels.

[0010] Furthermore, a transmission mechanism is vertically installed between the two sets of synchronous belts, toothed blocks are distributed on the outer side of the synchronous belts, and toothed grooves corresponding to the toothed blocks are provided on the inner side of the longitudinal guide rail.

[0011] Furthermore, the transverse guide rail is provided with a sliding groove that runs through the front and rear. The upper part of the guide frame is slidably connected to the sliding groove. The top of the guide frame is provided with a guide groove corresponding to the transmission mechanism. A fixing member is provided on the lower inner side of the guide frame. The piston cylinder is slidably connected to the fixing member. When the first motor starts, it drives two sets of synchronous belts through the action of two sets of drive wheels and the transmission mechanism connected between the two sets of drive wheels. Then, through the transmission mechanism and the guide frame, it drives the spray assembly and the high-pressure washing assembly to move laterally. When the spray assembly and the high-pressure washing assembly move close to the edge of the transverse guide rail, the toothed block engages the sliding groove, causing the transverse guide rail to move, thereby enabling the spray assembly and the high-pressure washing assembly to move over the mesh plate.

[0012] Furthermore, the drive mechanism includes a second motor fixedly mounted on the side of the transverse guide rail. A gear rod is fixedly connected to the output end of the second motor. The gear rod is arranged laterally and located below the transverse guide rail. A transmission disk is rotatably connected to the inner center of the guide frame through a fixed frame, and the transmission disk is meshed with the gear rod. The gear rod is a component consisting of a shaft and teeth distributed around the outside of the shaft, and the outer teeth of the gear rod are distributed laterally. An eccentric shaft is fixedly mounted on the side of the transmission disk near the edge. A movable shaft is fixedly mounted on the top of the piston cylinder. A movable rod is connected between the movable shaft and the eccentric shaft. When the second motor rotates, it drives the transmission disk to rotate through the gear rod, and then drives the piston cylinder to move up and down through the movable rod. The transmission disk does not affect the meshing connection with the gear rod after moving with the guide frame.

[0013] Furthermore, a groove is provided at the lower interior of the piston cylinder, and the pressing mechanism includes a pressing rod slidably disposed inside the groove, with the bottom of the pressing rod extending to the lower part of the piston cylinder. A second spring is installed between the top of the pressing rod and the inner wall of the top of the groove. When the piston cylinder gradually contacts the surface of the mesh plate downwards, the pressing rod contacts the mesh plate first and moves upwards.

[0014] Furthermore, inclined blocks are evenly distributed around the outer perimeter of the valve plate, and guide blocks are fixedly connected to the pressure rod. Two sets of guide blocks are arranged corresponding to the inclined blocks. When the pressure rod moves upward, the valve plate rotates by squeezing the inclined blocks through the guide blocks, and the first liquid outlet hole aligns with the second liquid outlet hole. At this time, the cleaning fluid inside the piston chamber moves rapidly downward under the pressure of the first spring, and the cleaning fluid passes through the valve plate and the first liquid outlet hole to contact the mesh plate. Under pressure, the cleaning fluid passes through the mesh plate to achieve powerful rinsing. Finally, under the conveyor belt, the cleaned mesh plate enters the dryer for drying.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a dual-spray automatic cleaning and drying machine for cleaning stencils. Through the coordinated operation of the spray assembly and the high-pressure rinsing assembly, it achieves a comprehensive and deep cleaning function for printed circuit stencils. The spray assembly utilizes spray holes with different tilt angles to form a high-pressure water flow under the action of the cleaning pump, which performs a preliminary and extensive cleaning of the stencil surface, rinsing away some residual solder paste. When the piston cylinder in the high-pressure rinsing assembly contacts the stencil, it can precisely trigger the valve plate to rotate, opening the corresponding liquid outlet. Under spring pressure, a powerful jet is generated, penetrating deep into the tiny pores of the stencil, effectively removing residual solder paste, achieving a significant improvement in cleaning cleanliness, and solving the problem that existing cleaning equipment is unable to clean solder paste inside the pores.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To address the technical problem of low cleaning efficiency in existing cleaning equipment, such as... Figures 1-8 As shown, the following preferred technical solutions are provided: like Figures 1-3 As shown, a dual-spray automatic cleaning and drying machine for cleaning mesh plates includes a cleaning tank 1 and a dryer 5. A moving component 2 is arranged at the top inside the cleaning tank 1, and a spray component 3 and a high-pressure rinsing component 4 are installed below the moving component 2. The moving component 2 is used to drive the spray component 3 and the high-pressure rinsing component 4 to be precisely positioned on a fixed-size area of ​​the mesh plate for rinsing. The spray component 3 includes a guide frame 31 installed on the moving component 2, and the high-pressure rinsing component 4 includes a piston cylinder 41 movably arranged inside the guide frame 31. The spray component 3 also includes a sprayer 32 installed outside the piston cylinder 41. A metal hose 33 is connected to the sprayer 32. The metal hose 33 extends to the outside of the cleaning tank 1 and is connected to the cleaning water tank and its cleaning pump. like Figures 6-8As shown, the piston cylinder 41 has a piston chamber 411 inside. A first spring 412 is fixedly installed on the upper part of the piston chamber 411. A piston plate 413 is installed below the first spring 412 and is in contact with the inner wall of the piston cylinder 41. The lower part of the piston cylinder 41 is connected to a metal hose 33 through a one-way inlet valve 42. The high-pressure flushing assembly 4 also includes a drive mechanism 43 installed below the spray assembly 3. The drive mechanism 43 is used to drive the piston cylinder 41 to move downward and fit against the top of the mesh plate. The flushing assembly 4 also includes a valve plate 45 rotatably disposed inside the lower part of the piston cylinder 41. The top of the valve plate 45 is evenly distributed with first liquid outlet holes 451. The lower part of the piston cylinder 41 is evenly distributed with second liquid outlet holes 46 above the valve plate 45. The lower part of the piston cylinder 41 is also equipped with a drive mechanism 43 extending to the bottom of the piston cylinder 41. The drive mechanism 43 is used to drive the valve plate 45 to rotate when the piston cylinder 41 contacts the mesh plate, so that the first liquid outlet holes 451 on the valve plate 45 correspond to the second liquid outlet holes 46.

[0020] like Figure 1 As shown, a conveyor belt 11 is provided at the bottom of the interior of the cleaning tank 1. The conveyor belt 11 extends into the interior of the dryer 5 and is used to support the screen and convey the screen.

[0021] like Figure 7 As shown, the sprayer 32 has an inner cavity 321 inside. Spray holes 322 are evenly distributed inside the lower part of the sprayer 32. The inclination angle of the spray holes 322 away from the center point of the sprayer 32 is greater than that of the spray holes 322 near the center point of the sprayer 32. One end of the metal hose 33 extends into the inner cavity 321. The cleaning liquid is delivered into the inner cavity 321 by an external cleaning pump, and a high-pressure water flow impact is formed at the spray holes 322.

[0022] like Figure 5 As shown, the moving component 2 includes a longitudinal guide rail 21 fixedly installed on the inner wall of the cleaning tank 1 and a transverse guide rail 22 slidably installed on the longitudinal guide rail 21. The moving component 2 also includes a first motor 23 installed on the top of the transverse guide rail 22 and a moving mechanism 24 and a transmission mechanism 25 installed inside the transverse guide rail 22.

[0023] The moving mechanism 24 has two sets, located above and below the transverse guide rail 22 respectively. The moving mechanism 24 includes a synchronous belt 241, and driving wheels 243 and driven wheels 244 located on both sides inside the synchronous belt 241. The driving wheels 243 and driven wheels 244 are rotatably mounted inside the transverse guide rail 22, and the two sets of driving wheels 243 are connected by a transmission mechanism 25. The transmission mechanism 25 is a transmission structure composed of a transmission shaft and a gear set. The output end of the first motor 23 extends into the transverse guide rail 22 and is fixedly connected to one set of driving wheels 243. The transmission mechanism 25 is vertically installed between the two sets of synchronous belts 241. Tooth blocks 242 are distributed on the outer side of the synchronous belts 241, and tooth grooves 211 corresponding to the tooth blocks 242 are provided on the inner side of the longitudinal guide rail 21. The transverse guide rail 22 has a sliding rail that runs through it from front to back. The upper part of the guide frame 31 is laterally slidably connected to the sliding groove 221. The top of the guide frame 31 is provided with a guide groove 311 corresponding to the transmission mechanism 25. A fixing member 312 is provided on the lower inner side of the guide frame 31. The piston cylinder 41 is slidably connected to the fixing member 312. When the first motor 23 starts, it drives the two sets of synchronous belts 241 through the action of the two sets of driving wheels 243 and the transmission mechanism 25 connected between the two sets of driving wheels 243. Then, through the transmission mechanism 25 and the guide frame 31, it drives the spray assembly 3 and the high-pressure washing assembly 4 to move laterally. When the spray assembly 3 and the high-pressure washing assembly 4 move close to the edge of the transverse guide rail 22, the tooth block 242 engages the sliding groove 221 to displace the transverse guide rail 22, thereby enabling the spray assembly 3 and the high-pressure washing assembly 4 to move over the screen.

[0024] like Figures 5-6 As shown, the drive mechanism 43 includes a second motor 431 fixedly mounted on the side of the transverse guide rail 22. A gear rod 432 is fixedly connected to the output end of the second motor 431. The gear rod 432 is arranged laterally and located below the transverse guide rail 22. A transmission disk 433 is rotatably connected to the inner center of the guide frame 31 via a fixing frame 313, and the transmission disk 433 meshes with the gear rod 432. The gear rod 432 is a component consisting of a shaft and teeth distributed around the outer side of the shaft, with the outer teeth of the gear rod 432 distributed laterally. An eccentric shaft 4331 is fixedly installed on the side of the transmission disc 433 near the edge, and a movable shaft 4333 is fixedly installed on the top of the piston cylinder 41. A movable rod 4332 is connected between the movable shaft 4333 and the eccentric shaft 4331. When the second motor 431 rotates, it drives the transmission disc 433 to rotate through the gear rod 432, which in turn drives the piston cylinder 41 to move up and down through the movable rod 4332. The transmission disc 433 does not affect the meshing connection with the gear rod 432 after it moves with the guide frame 31.

[0025] The piston cylinder 41 has a groove 414 at its lower interior. The pressing mechanism 44 includes a pressing rod 442 that is slidably disposed inside the groove 414. The bottom of the pressing rod 442 extends to the bottom of the piston cylinder 41. A second spring 441 is installed between the top of the pressing rod 442 and the inner wall of the top of the groove 414. When the piston cylinder 41 gradually contacts the surface of the mesh plate downwards, the pressing rod 442 contacts the mesh plate first and moves upwards.

[0026] like Figure 8 As shown, inclined blocks 452 are evenly distributed around the outer perimeter of the valve plate 45. Guide blocks 443 are fixedly connected to the pressure rod 442. Two sets of guide blocks 443 are arranged corresponding to the inclined blocks 452. When the pressure rod 442 moves upward, the valve plate 45 rotates by squeezing the inclined blocks 452 through the guide blocks 443, and the first liquid outlet 451 aligns with the second liquid outlet 46. At this time, the cleaning fluid inside the piston chamber 411 is under the pressure of the first spring 412, and the piston plate 413 moves downward rapidly, allowing the cleaning fluid to pass through the valve plate 45 and the first liquid outlet 451 to contact the mesh plate. Under pressure, the cleaning fluid passes through the mesh plate to achieve powerful rinsing. Finally, under the conveyor belt 11, the cleaned mesh plate enters the dryer 5 for drying.

[0027] Specifically, at the start of the operation, the printed circuit board with residual solder paste is transported to the designated cleaning position by the conveyor belt 11 at the bottom of the cleaning tank 1. The external cleaning pump delivers the cleaning fluid through pipes and metal hoses 33 to the inner cavity 321 of the sprayer 32 and the piston chamber 411 of the piston cylinder 41, compressing the first spring 412 until it can no longer be compressed. Due to the distribution characteristics of the spray holes 322 at the bottom of the sprayer 32, the spray holes 322 far from the center point have a large inclination angle. After the cleaning fluid enters the inner cavity 321... High-pressure water jets are generated and sprayed from the spray holes 322 to perform preliminary cleaning of the stencil surface, rinsing away some residual solder paste. The second motor 431 on the side of the transverse guide rail 22 starts, driving the gear rod 432 to rotate. The gear rod 432 meshes with the transmission disc 433, driving the piston cylinder 41 downward through the eccentric shaft 4331 and the movable rod 4332. When the piston cylinder 41 contacts the top of the stencil, the contact rod 442 inside the piston cylinder 41 contacts the stencil and moves upward, driving the guide block 443 to squeeze the inclined block 452 of the valve plate 45, causing the valve to... The plate 45 rotates, aligning the first liquid outlet 451 with the second liquid outlet 46. At this time, the first spring 412 releases pressure, pushing the piston plate 413 downward. The cleaning fluid forms a high-pressure jet through the second liquid outlet 46, the valve plate 45, and the first liquid outlet 451, powerfully flushing away residual solder paste in the mesh aperture. The first motor 23 at the top of the transverse guide rail 22 starts, driving the drive wheel 243 to rotate. Through the transmission mechanism 25, the synchronous belt 241 is driven, and the toothed block 242 engages with the toothed groove 211 of the longitudinal guide rail 21 and connects with the guide frame 31. Next, the spray assembly 3 and the high-pressure rinsing assembly 4 move laterally to clean different positions of the screen. When it approaches the edge of the transverse guide rail 22, the toothed block 242 and the sliding groove 221 act to displace the transverse guide rail 22, expanding the cleaning coverage area. The longitudinal guide rail 21 is fixed to the inner wall of the cleaning box 1, and the transverse guide rail 22 slides back and forth on it, working together to achieve all-round cleaning of the screen. After cleaning, the screen enters the dryer 5 under the action of the conveyor belt 11 to remove residual moisture, completing the entire cleaning and drying process, so that the screen can be used again for printed circuit production.
