Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.
[0047] like Figures 1 to 2As shown, the X direction shown in the figure is a schematic diagram of the sliding direction of the baffle, and the Y direction shown in the figure is a schematic diagram of the conveying direction of the substrate. The embodiment of the first aspect of the present utility model provides a spraying material blocking device 1, which includes a machine 11, a baffle 12, a position monitoring component 13 and a drive component 14. A bracket 111 is provided on the machine 3, and the baffle 12 is used to block part of the spray port 21, that is, the baffle 12 can be set at the spray port 21 to facilitate partial blocking of the spray port 21, so that the sprayed slurry outside the substrate 3 can be blocked by the baffle 12 and flow back into the material box 2, thereby improving the slurry utilization rate. The position monitoring component 13 is connected to the baffle 12, and the position monitoring component 13 can be used to monitor the position of the substrate 3, that is, the position monitoring component 13 can be set at a position close to the substrate 3 to monitor the position of the substrate 3 in real time, so as to timely judge the position of the substrate 3 relative to the baffle 12.
[0048] Detect the working distance between the baffle 12 and the substrate 3, Figure 2 D in the middle is a schematic diagram of the working distance. The position monitoring component 13 can monitor the working distance between the edge of the baffle 12 and the edge of the substrate 3 in real time. The driving component 14 is fixed on the bracket 111, and the driving component 14 is connected to the baffle 12 in a transmission manner. The driving component 14 can drive the baffle 12 to slide, so that the baffle 12 can slide and switch to different blocking positions at the spray port 21, blocking the flow area of the spray port 21 to different degrees, and can also adjust the working distance between the baffle 12 and the substrate 3 to a preset distance. The working distance between the baffle 12 and the substrate 3 can be detected and adjusted in real time, wherein the working distance refers to the actual distance between the baffle 12 and the substrate 3 when working, and the preset distance refers to the target distance value between the baffle 12 and the substrate 3 that is pre-set according to the material blocking needs.
[0049] In this arrangement, when the position monitoring component 13 detects that the position of the substrate 3 is too far relative to the baffle 12, that is, the edge of the baffle 12 is far away from the edge of the substrate 3, the driving component 14 can drive the baffle 12 to slide toward the substrate 3, so that the baffle 12 and the substrate 3 are sprayed with a preset distance between them. When the position monitoring component 13 detects that the position of the substrate 3 is too close relative to the baffle 12, that is, the edge of the baffle 12 is close to the edge of the substrate 3, the driving component 14 can drive the baffle 12 to slide away from the substrate 3, so that the baffle 12 and the substrate 3 are sprayed with a preset distance between them. When the position monitoring component 13 detects that the position of the substrate 3 is moderate relative to the baffle 12, the driving component 14 stops driving, so that the baffle 12 and the substrate 3 can maintain the spraying barrier at the preset distance.
[0050] The position detection component 13 of this embodiment is arranged close to the substrate 3, and can perform real-time position monitoring and timely adjustment of the working distance between the baffle 12 and the substrate 3, so that the baffle 12 and the substrate 3 maintain the spray barrier at a preset distance. It can reduce the situation where the distance between the baffle 12 and the substrate 3 is too close, the baffle 12 excessively blocks the slurry, and there is less slurry sprayed on the surface of the substrate 3. It can also reduce the situation where the distance between the baffle 12 and the substrate 3 is too far, the slurry sprayed from the distance between the baffle 12 and the substrate 3 is difficult to flow back into the material box 2, and the slurry utilization rate is reduced. It also reduces manual labor intensity and labor costs, and the spraying work is more efficient and convenient, which solves the problem in the related art that the distance between the baffle and the substrate needs to be manually adjusted when spraying the substrate, which is prone to less spraying or reduced slurry utilization.
[0051] In this embodiment, the bracket 111 can be mounted on the magazine 2 or on both sides of the magazine 2. The baffle 12 can be slidably connected to the magazine 2, and the relative sliding direction between the baffle 12 and the magazine 2 intersects the conveying direction of the substrate 3. For example, the relative sliding direction between the baffle 12 and the magazine 2 is perpendicular to the conveying direction of the substrate 3, or the relative sliding direction between the baffle 12 and the magazine 2 can be set at a certain angle that deviates from the perpendicular to the conveying direction of the substrate 3. It is sufficient that the baffle 12 and the magazine 2 can slide relative to each other to move closer to or away from the substrate 3. The drive assembly 14 can be, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, an electric telescopic rod, or a combination of a motor and a screw nut, and can provide driving force for the sliding of the baffle 12.
[0052] like Figures 1 to 2 As shown, in some embodiments, the position monitoring assembly 13 includes a connecting frame 131 and a monitor 132. The connecting frame 131 is connected to the baffle 12. The connecting frame 131 is provided with an open slot 1311 for allowing the substrate 3 to pass through. The monitor 132 is provided in the open slot 1311. The monitor 132 is capable of emitting a detection signal. Optionally, the transmission path of the detection signal is provided along the radial extension of the screw 142. When the side edge of the substrate 3 extends into the open slot 1311 and is located on the transmission path of the detection signal, it means that the side edge of the substrate 3 can block part of the detection signal, the position of the side edge of the substrate 3 can be detected by the monitor 132 and the position is appropriate. At this time, the working distance between the baffle 12 and the substrate 3 is equal to the preset distance, and the driving assembly 14 stops driving the baffle 12, and the relative position of the baffle 12 and the substrate 3 remains unchanged.
[0053] In some embodiments, the monitor 132 includes one or more detection terminals, each of which is disposed on the inner wall of the opening slot 1311. The detection terminals are capable of detecting the position of the substrate 3 within the opening slot 1311. When there are multiple detection terminals, the multiple detection terminals are sequentially spaced apart perpendicularly to the transport direction of the substrate 3, so as to perform multi-point detection perpendicular to the transport direction of the substrate 3. The detection signal transmission path of the detection terminal can be along the vertical direction of the substrate 3. After the substrate 3 enters the opening slot 1311, the detection signals of the multiple detection terminals can be blocked respectively, thereby accurately determining the edge position of the substrate 3, reducing the position detection error of the substrate 3 caused by the thin thickness of the substrate 3 and the up and down vibration during transportation, and improving the accuracy of the position detection of the substrate 3.
[0054] Among them, one or more detection ends can be set only at the position where the preset spacing range is satisfied between the substrate 3 and the baffle 12, or multiple detection ends can be set at the position where the preset spacing range is satisfied between the substrate 3 and the baffle 12 and at the position adjacent to the preset spacing range in the transport direction perpendicular to the substrate 3, so as to accurately detect and predict the position of the substrate 3.
[0055] In some embodiments, the connecting frame 131 is arranged on the end face of the baffle 12 facing the substrate 3. With this arrangement, the connecting frame 131 is small in size, light in weight, and short in length, which can reduce the squeezing of the baffle 12 and the vibration generated by the connecting frame 131 during the movement of the baffle 12, thereby facilitating the accurate entry of the substrate 3 into the open groove 1311 during the transportation process, and making the position detection of the substrate 3 more accurate and convenient.
[0056] In some other embodiments, the connecting frame 131 may also be arranged on the side of the baffle 12, with the opening groove 1311 facing the substrate 3, so as to reduce the positional interference between the setting position of the connecting frame 131 and the installation of the substrate 3 or the baffle 12 caused by the limited space between the baffle 12 and the substrate 3. When the connecting frame 131 is installed on the side of the baffle 12, there is sufficient installation space and the connection area with the baffle 12 is large.
[0057] In some embodiments, the monitor 132 may be, but is not limited to, a position sensor, an infrared sensor, a visual detection system, or an ultrasonic sensor. The visual detection system can provide intuitive and accurate positioning information, respond quickly, and is suitable for high-speed motion environments, providing greater automation and intelligence. Ultrasonic sensors provide non-contact measurement, strong environmental adaptability, a wide measurement range, high accuracy, and strong anti-interference capabilities.
[0058] Specifically, the monitor 132 can be an ultrasonic sensor, which includes a sensor body, a transmitting element and a receiving element. The sensor body is connected to the connecting frame 131. The transmitting element and the receiving element can be set on the groove wall of the opening groove 1311. The transmitting element and the receiving element can be set on the same groove wall of the opening groove 1311 to form a reflective detection, or they can be set on the opposite groove wall of the opening groove 1311 to form a transmissive detection. The detection signal emitted by the transmitting element can be received by the receiving element directly or after reflection or transmission through the substrate 3.
[0059] When the side edge of substrate 3 extends into and blocks the transmitting element and the receiving element, the transmitting element's transmitted signal is partially blocked by the edge of substrate 3, and the receiving element only receives a portion of the transmitted signal. The sensor body can transmit an appropriate distance signal, and the drive assembly 14 stops driving baffle 12. The working distance between baffle 12 and substrate 3 is equal to the preset distance, indicating that the distance between baffle 12 and substrate 3 is now appropriate. When the edge of substrate 3 is farther away from monitor 132, there is no substrate 3 blocking the transmitting element and the receiving element. The receiving element receives the entire transmitted signal from the transmitting element, and the sensor body can transmit a long-distance signal. The drive assembly 14 drives baffle 12 closer to substrate 3. When the width of substrate 3 extending into the detection space is greater, the transmitting element's transmitted signal is blocked by substrate 3, and the sensor body transmits a short-distance signal. The drive assembly 14 can drive baffle 12 away from substrate 3.
[0060] like Figures 1 to 2 As shown, in some embodiments, the spraying material blocking device 1 also includes a main control box 15, and the position monitoring component 13 and the driving component 14 are both communicatively connected to the main control box 15. The main control box 15 can allow the user to pre-set a preset distance, and the distance detection signal of the position monitoring component 13 can be transmitted to the main control box 15. After judgment or processing by the main control box 15, the main control box 15 controls the driving action of the driving component 14, and the position adjustment operation of the baffle 12 is more accurate and intelligent.
[0061] like Figures 1 to 2 As shown, in some embodiments, at least two groups of spray blocking devices 1 are provided, and at least two groups of spray blocking devices 1 are respectively arranged on both sides of the substrate 3, which can block the slurry on both sides of the substrate 3, and the side edges on both sides of the substrate 3 and the baffle 12 can be flexibly adjusted.
[0062] In this embodiment, two groups of spray blocking devices 1 can be provided. Alternatively, if the spraying distance required for the substrate 3 is long, the spray blocking devices 1 can be arranged in groups of two, extending along the conveying direction of the substrate 3, to provide multiple groups to fully block the slurry. When multiple spray blocking devices 1 are provided, the multiple spray blocking devices 1 can share the same main control box 15.
[0063] In some embodiments, the preset distance between the baffle 12 and the substrate 3 is in the range of 4 cm to 6 cm. Optionally, the preset distance can be selected as 5 cm, which can not only provide a certain offset gap for the substrate 3, but also fully block the sprayed slurry outside the membrane surface, allowing it to flow back into the material tank, thereby improving the slurry utilization rate.
[0064] like Figures 1 to 2 As shown, in some embodiments, the drive assembly 14 includes a drive member 141, a screw 142, and a nut 144. The drive member 141 is disposed on the bracket 111. The drive member 141 can be supported by the bracket 111 to maintain a stable position. The screw 142 is rotatably connected to the bracket 111. The baffle 12 is disposed on the screw 142, and the baffle 12 is threadedly connected to the screw 142. The screw 142 is transmission-connected to the drive member 141, that is, the screw 142 has a certain length, and one or both ends of the screw 142 can be rotatably mounted on the bracket 111, supported by the bracket 111 to reduce the shaking of the screw 142. The nut 144 is sleeved on the screw 142 and threadedly connected to the screw 142. The rotation of the screw 142 can drive the nut 144 to move along the axial direction of the screw 142. The baffle 12 is arranged on the nut 144, and the baffle 12 is fixedly connected to the nut 144, and the screw 142 is in transmission connection with the driving member 141.
[0065] With such a configuration, the driving member 141 can be supported by the bracket 111, and the driving member 141 drives the screw 142 to rotate. The screw 142 drives the nut 144 and the baffle 12 to move along the axial direction of the screw 142 through the connecting thread, thereby switching and adjusting the working distance between the edge of the baffle 12 and the edge of the substrate 3. The moving distance is accurately adjusted through the thread feed, and there is a certain self-locking force between the nut 144 and the screw 142 at the stop position to reduce shaking.
[0066] Optionally, the driving member 141 may be, but is not limited to, a motor, a cylinder or a hydraulic cylinder. The sliding between the baffle 12 and the bracket 111 may be achieved by relative sliding through surface contact, or by providing a sliding structure such as a slide groove.
[0067] like Figure 1 As shown, in some embodiments, the drive assembly 14 also includes a guide rail 143, which extends perpendicular to the movement direction of the substrate 3, and the baffle 12 is slidingly connected to the guide rail 143. In this way, the guide rail 143 can guide the sliding between the bracket 111 and the baffle 12, thereby avoiding the displacement or shaking of the baffle 12 relative to the bracket 111 in the radial direction of the screw 142, thereby improving the position accuracy of the baffle 12 for blocking the slurry.
[0068] In this embodiment, the guide rail 143 can be connected to the machine platform 11 or supported and fixed by an external support frame. The cross-section of the guide rail 143 can be, but is not limited to, a square, an inverted trapezoidal, or a dovetail shape. The inverted trapezoidal or dovetail cross-section allows the guide rail 143 to form a larger upper portion and smaller lower portion of a retaining structure, thereby reducing the possibility of separation between the baffle 12 and the guide rail 143.
[0069] like Figure 1 As shown, in some embodiments, a plurality of guide rails 143 are provided, and the plurality of guide rails 143 are all extended along the axial direction of the screw 142 and are arranged on both sides of the screw 142. In the conveying direction of the substrate 3, due to the need for spraying, the baffle 12 needs to have a certain span. The plurality of guide rails 143 are provided on both sides of the screw 142 to slide and support the baffle 12, which can reduce the deformation or shaking of the baffle 12 and improve the accuracy of the baffle 12 blocking position.
[0070] like Figures 2 to 3 As shown, in some embodiments, the guide rail 143 is arranged on the side of the baffle 12 and is slidably connected to the side wall of the baffle 12. The bottom wall of the baffle 12 is used to fit with the surface of the material box 2 provided with the spray port 21. The bottom wall of the baffle 12 fits with the surface of the material box 2 and can slide with each other, so as to effectively block the spray port 21 and reduce the overflow of paint from the bottom wall of the baffle 12 and the surface of the material box 2. The guide rail 143 is arranged on the side of the baffle 12, which can not only increase the fitting contact area between the bottom wall of the baffle 12 and the material box 2, but also limit the vertical direction of the sliding direction of the baffle 12, reduce the vibration or displacement of the baffle 12, and enable the baffle 12 to maintain contact with the surface of the material box 1 to avoid slurry overflow.
[0071] Among them, an extension piece 121 is provided on the bottom wall of the baffle 12, and the extension piece 121 is at least partially located in the spray port 21. One or more grooves 122 are provided on the side wall and / or bottom wall of the extension piece 121. The groove 122 is used to accommodate the slurry, that is, the groove 122 can provide a certain accommodation space for the slurry on the side wall or bottom wall of the extension piece 121. When the slurry flows to the position of the extension piece 121 during the spraying process and tends to overflow outward, the paint will enter the groove 122. The groove 122 can provide an accommodation space to slow down the overflow of the slurry.
[0072] Optionally, the sidewall of the extension piece 121 can fit with the sidewall of the spray port 21 or a certain distance can be reserved between the sidewall of the spray port 21. The groove 122 can be a strip groove or an annular groove, and the groove 122 can be arranged along the circumference of the extension piece 121.
[0073] like Figure 2As shown, an embodiment of the second aspect of the present invention provides a spraying equipment, including a material box 2 and a spray blocking device 1 in any of the above-mentioned schemes, wherein the baffle 12 is arranged at the spray port 21 of the material box 2 and blocks part of the spray port 21, and can timely adjust the working distance between the baffle 12 and the substrate 3, so that the spray blocking operation is maintained at a preset distance between the baffle 12 and the substrate 3, which can reduce the situation where the distance between the baffle 12 and the substrate 3 is too close, the baffle 12 excessively blocks the slurry, and there is less slurry sprayed on the surface of the substrate 3, and can also reduce the situation where the distance between the baffle 12 and the substrate 3 is too far, the slurry sprayed from the distance between the baffle 12 and the substrate 3 is difficult to flow back into the material box 2, and the slurry utilization rate is reduced, and the labor intensity and labor cost are reduced, and the spraying work of the spraying equipment is more efficient and convenient.
[0074] Among them, the bracket 111 and the material box 2 are both set on the machine platform 11, and the bracket 111 is connected to the machine platform 11. The machine platform 11 can set up and support one or more groups of spray blocking devices 1, and can provide a unified installation reference for multiple groups of spray blocking devices 1.
[0075] In certain embodiments, the spraying equipment further comprises a spin spraying member 22, the spin spraying member 22 being arranged in the cartridge 2, the ejection end of the spin spraying member 22 being arranged towards the spraying port 21, the cartridge 2 being able to hold slurry, the inlet of the spin spraying member 22 being able to be immersed below the liquid level of the slurry, the spin spraying member 22 being pressurized and atomized to spray the slurry onto the surface of the substrate 3, so as to coat the surface of the substrate 3. The spin spraying member 22 can be, but is not limited to, a rotary nozzle, a fan nozzle or a universal DC nozzle. The spin spraying member 22 can be provided with a plurality of, and a plurality of spin spraying members 22 are arranged to extend vertically along the conveying direction of the substrate 3, so as to spray the substrate 3 over a large area at multiple points.
