[0002] Steel mesh is a key tool in surface mount technology (SMT) process, which is used to accurately print solder paste on the pads of the circuit board. During use, the mesh holes of the steel mesh are prone to residual solder paste, which will directly affect the subsequent printing quality and cause welding defects if not cleaned in time. In addition, the steel mesh may be subject to tension reduction, deformation or damage after long-term use and repeated cleaning, which will further affect the printing accuracy if not regularly inspected.

[0003] Currently, the cleaning and inspection of the steel mesh are usually completed by independent equipment or manual operation. The conventional cleaning equipment adopts fixed liquid spraying and wiping methods, which consumes a large amount of cleaning agent and is difficult to accurately clean the local contaminated area. The waste liquid generated by the cleaning machine needs to be separately stored and recycled by a professional agency at a certain cost. At the same time, the conventional inspection equipment often needs manual intervention or complex programming settings to position the steel mesh and identify the inspection area, which is tedious in operation process, low in efficiency, and requires high skills of the operator.

Detailed Implementation

[0017] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0018] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] like Figures 1 to 7 As shown, this invention provides a programmable, zero-waste-discharge integrated steel mesh washing and inspection device, comprising a frame 1. The frame 1 is equipped with a placement fixture 3 for placing the steel mesh, a spraying mechanism 4 for cleaning and wiping the steel mesh, an upper wiping mechanism 5 and a lower wiping mechanism 6, a visual inspection mechanism 7 for visually inspecting the steel mesh, and a lighting mechanism 8. An X-axis moving mechanism 9 is arranged along the X-axis direction, a Y-axis moving mechanism 10 is arranged along the Y-axis direction, and a Z-axis moving mechanism 11 is arranged along the Z-axis direction. The spraying mechanism 4 and the Z-axis moving mechanism 11 are movably mounted on the X-axis moving mechanism 9. The upper wiping mechanism 5 and the lower wiping mechanism 6 are both movably mounted on the Y-axis moving mechanism 10. The visual inspection mechanism 7 is movably mounted on the Z-axis moving mechanism 11.

[0020] Furthermore, the placement fixture 3 includes two strip-shaped placement plates 31 respectively arranged along the Y-axis direction, and a baffle 32 that limits the steel mesh in the X-axis direction. The strip-shaped placement plates 31 and the baffle 32 form an L-shaped structure. The baffle 32 is connected to the frame 1 through a support plate 33, so that the placement fixture 3 is fixed on the frame 1. The placement fixture 3 of the present invention is not limited to the above structure. The placement fixture 3 can also be two U-shaped grooves (not shown) symmetrically arranged on the frame 1, and the steel mesh can be placed on the placement fixture 3 through the openings of the U-shaped grooves.

[0021] Furthermore, both the upper wiping mechanism 5 and the lower wiping mechanism 6 include a rotatable output roller 51, a take-up roller 52, and wiping paper 53 wound on the output roller 51 and the take-up roller 52. The output roller 51 and the take-up roller 52 are parallel to each other, and the output roller 51 and the take-up roller 52 are connected to a drive device (such as a motor) for driving the output roller 51 and the take-up roller 52 to rotate.

[0022] The upper wiping mechanism includes a pressing device 54 on the side of the paper output roller 51 and paper take-up roller 52 near the stencil, used to press the wiping paper 53 against the stencil. The pressing device 54 consists of a pressing plate base 541 and several strip-shaped pressing plates 542 mounted on the pressing plate base 541. The pressing plate base 541 has grooves for placing the pressing plates 542. Each pressing plate 542 has a wedge-shaped end section, which facilitates pressing against the wiping paper 53. As the pressing plates 542 move back and forth, they cause the wiping paper 53 to move back and forth on the stencil for wiping. The pressing plates 541 are made of silicone, which has good flexibility and can tightly adhere the wiping paper 53 to the stencil surface, removing residual solder paste without damaging the wiping paper 53. The pressure plate base 541 has a long, narrow groove 543 at its center, with the length of the groove 543 along the X-axis. This groove allows the nozzle 41 of the spraying mechanism 4 to pass through the pressure plate base 541 and drip cleaning liquid onto the wiping paper 53. Guide rollers 55 are located on both sides of the pressure plate base 541 to guide the wiping paper 53. In use, a clean wiping paper 53 is placed on the paper output roller 51. The wiping paper 53 is pulled out and wound onto the take-up roller 52. Cleaning agent is sprayed onto the wiping paper 53. The upper wiping mechanism 9 and the lower wiping mechanism 11 move back and forth, causing the wiping paper 53 to wipe the steel mesh. After wiping, the paper output roller 51 and the take-up roller 52 rotate in the same direction, winding the soiled wiping paper 53 onto the take-up roller 52.

[0023] Furthermore, the present invention may also provide an air extraction hole (not shown) at the bottom of the lower wiping mechanism 6 for connecting a vacuum pump (not shown). In use, the vacuum pump draws air through the air extraction hole to remove dust from the steel mesh.

[0024] Furthermore, the X-axis moving mechanism 9 includes a first X-axis moving mechanism 91 and a second X-axis moving mechanism 92. The first X-axis moving mechanism 91 includes a first X-axis guide rail 911 arranged along the X-axis direction and a first X-axis slider 912 movably arranged on the first X-axis guide rail 911. A connecting plate 12 is provided on the first X-axis slider 912, and the visual inspection mechanism 7 is connected to the first X-axis slider 912 through the connecting plate 12, enabling the visual inspection mechanism to move along the X-axis direction. The visual inspection mechanism 7 includes a camera device 71 capable of scanning and photographing the stencil and a tension meter 72 for detecting the tension of the stencil. The tension meter 72 promptly detects and addresses issues of insufficient or excessive tension, preventing printing defects caused by stencil deformation, thereby ensuring the stability and reliability of subsequent production.

[0025] The Z-axis moving mechanism 11 includes a first Z-axis moving mechanism 111 connected to the visual inspection mechanism 7 and a second Z-axis moving mechanism 112 connected to the upper wiping mechanism 5. The camera device 71 and the tension meter 72 are respectively mounted on the two first Z-axis moving mechanisms 111, enabling them to move up and down along the Z-axis. The first Z-axis moving mechanism 111 of this invention can be a cylinder or an electric actuator, etc., as long as it can achieve its function. The camera device 71 and the tension meter 72 of this invention are both existing structures commonly found in the art, as long as they can achieve their functions.

[0026] The bottom of the first X-axis guide rail 911 is provided with a first X-axis guide rail base plate 913. The first X-axis guide rail base plate 913 is connected to a crossbeam 14 located on one side of the first X-axis moving mechanism 91 via an electromagnet 13. The upper wiping mechanism 5 is mounted on the crossbeam 14 via a second Z-axis moving mechanism 112 and a support frame 15 connected to the upper wiping mechanism, enabling the upper wiping mechanism 5 to move up and down along the Z-axis. The second Z-axis moving mechanism 112 of the present invention can be a cylinder or other structure, as long as it can achieve its function.

[0027] The second X-axis moving mechanism 92 is a synchronous belt mounted on the upper wiping mechanism 5. The spraying mechanism 4 is connected to the synchronous belt, enabling it to move along the X-axis. The spraying mechanism 4 includes a liquid nozzle 41 and a liquid nozzle solenoid valve 42 connected to the nozzle. The liquid nozzle 41 is positioned between the paper output roller 51 and the paper take-up roller 52 of the upper wiping mechanism 5 and can move back and forth above the wiping paper 53 in contact with the stencil via the second X-axis moving mechanism 92. Once the area of ​​the stencil that needs cleaning and wiping is determined, the spraying mechanism 4 moves above that area using the X-axis moving mechanism 9 and the Y-axis moving mechanism 10 to spray liquid onto the wiping paper 53 above that area. This eliminates the need to spray cleaning agent onto the entire open area of ​​the stencil; only the portion requiring cleaning and wiping needs to be sprayed, saving both cleaning and wiping time and cleaning agent costs.

[0028] The Y-axis moving mechanism 10 includes a first Y-axis moving mechanism 101 and at least one second Y-axis moving mechanism 102. The first Y-axis moving mechanism 101 and the second Y-axis moving mechanism 102 are respectively disposed on the upper and lower sides of the fixture 3. The first Y-axis moving mechanism 101 includes two first Y-axis guide rails 1011 respectively disposed on both sides of the frame 1, and a first Y-axis slider 1012 movably disposed on the first Y-axis guide rails 1011. The lower wiping mechanism 6 and the lighting mechanism 8 are both disposed on the first Y-axis slider 1012. Using the first Y-axis slider 1012, the lower wiping mechanism 6 and the lighting mechanism 8 can be moved back and forth along the Y-axis direction to facilitate wiping and lighting the steel mesh. The second Y-axis moving mechanism 102 includes two second Y-axis guide rails 1021 respectively disposed on both sides of the frame 1, and a second Y-axis slider 1022 movably disposed on the second Y-axis guide rails 1021. The first X-axis moving mechanism 91 and the crossbeam 14 are both connected to the second Y-axis slider 1022.

[0029] Furthermore, the lighting mechanism 8 includes a lighting body 81 and a lighting base plate 82 disposed at the bottom of the lighting body 81. The lighting base plate 82 is connected to the first Y-axis slider 1012. The lower wiping mechanism 6 is connected to the lighting mechanism 8 via an electromagnet 13. Controlled by the electromagnet 13, the lighting mechanism 8 and the lower wiping mechanism 6 can be connected together or disconnected, saving on the need for a drive unit. In use, the lower wiping mechanism 6 can be connected via a single drive unit. After the lower wiping mechanism 6 has finished its work, it can be moved to the position of the waiting lighting mechanism 8. The electromagnet 13 then attracts the lighting mechanism 8 and moves it along the Y-axis, providing supplementary lighting for visual inspection of the cleaned and wiped steel mesh.

[0030] This invention also includes a cleaning and inspection method for a programming-free, zero-waste-liquid-discharge integrated steel mesh cleaning and inspection device, comprising the following steps: S1: Place the steel mesh on the placement fixture 3. Use the first X-axis moving mechanism 91, the second Y-axis moving mechanism 102 and the first Z-axis moving mechanism 111 to drive the vision inspection mechanism 7 to move above the steel mesh. Use the vision inspection mechanism 7 to check the tension of the steel mesh and take an actual image of the steel mesh. Scan the QR code or barcode affixed to the steel mesh. The code includes the unique identifier of the steel mesh. Based on the scanned identifier, the program automatically retrieves the standard design drawing Gerber file corresponding to the steel mesh from a preset image database. S2: Through intelligent algorithms, it automatically finds two optimal feature points on standard design drawings and actual images of steel mesh, and generates inspection files without the need for manual programming; S3: Using the automatically generated stencil inspection file, the second Y-axis moving mechanism 102, the second X-axis moving mechanism 92, and the second Z-axis moving mechanism 112 are used to move the spraying mechanism 4 and the upper wiping mechanism 5 above the area of ​​the stencil that needs to be cleaned and wiped, and move the lower wiping mechanism 6 below the area. The spraying mechanism 4 sprays cleaning agent onto the wiping paper 53 in the area. The second Y-axis moving mechanism 102 drives the upper wiping mechanism 5 and the lower wiping mechanism 6 to move, and drives the pressure plate 542 to move so that the wiping paper 53 wipes back and forth on the stencil, thereby cleaning the stencil. S4: Driven by the first Y-axis moving mechanism 101, the wiping mechanism 6 moves to the waiting lighting mechanism 8. The electromagnet 13 is used to hold the lighting mechanism 8 and move it below the steel mesh to supplement the lighting of the steel mesh. The visual inspection mechanism 7 is used to visually inspect the steel mesh to check whether the steel mesh is clean.

[0031] The X-axis moving mechanism 9, Y-axis moving mechanism 10, and Z-axis moving mechanism 11 of the present invention are all connected to a driving device (not shown). The driving device is a common existing structure in the art, which is based on its ability to achieve its function.
