[0045] This embodiment provides a movable coating valve for coating adhesives onto the surface of a substrate, particularly suitable for coating adhesives onto thin film substrates. Please refer to... Figures 1-8The active coating valve includes a glue spraying assembly, a first adjusting mechanism, a second adjusting mechanism, a valve body assembly, and a high-speed solenoid valve 400. The glue spraying assembly includes a flow channel 10 and a glue spray head 20. The flow channel 10 extends vertically, with its upper end connected to the glue supply line and its lower end connected to the glue spray head 20. The first adjusting mechanism and the second adjusting mechanism are used to drive the glue spray head 20 to rotate around a horizontal axis and around a vertical axis, respectively. The output end of the valve body assembly extends and retracts through the flow channel 10 to adjust the glue dispensing rate. The high-speed solenoid valve 400 is used to control the on / off state of the glue supply line.
[0046] For further details, please refer to Figures 1-8 The glue spraying assembly also includes an adapter 30 and an adapter shaft 40. The adapter 30 is inserted into the lower end of the flow channel tube 10, and the adapter shaft 40 is fixedly connected to the adapter 30. The glue spraying head 20 is rotatably connected to the adapter shaft 40 in the horizontal direction. The adapter 30 is provided with a glue outlet 31 and a first flow channel 32. The output end of the valve body assembly can adjust the opening degree of the glue outlet 31 by telescopic adjustment. The glue outlet 31 connects the flow channel tube 10 and the first flow channel 32. The adapter shaft 40 is provided with a second flow channel 41, which connects the first flow channel 32 and the glue spraying head 20. The first adjustment mechanism can drive the glue spraying head 20 to rotate around the adapter shaft 40.
[0047] Specifically, in this embodiment, the movable coating valve has a spray head 20 that is rotatably connected to an adapter 30 via an adapter shaft 40. A first adjustment mechanism independently drives the spray head 20 to rotate horizontally, achieving pitch adjustment of the spray direction. By providing a first flow channel 32 on the adapter 30 and a second flow channel 41 on the adapter shaft 40, the first and second flow channels 32 and 41 connect the dispensing hole 31 and the spray head 20. Regardless of how the spray head 20 rotates, the positions of the first and second flow channels 32 and 41 remain unchanged, ensuring the glue flow path between the dispensing hole 31 and the spray head 20 remains unobstructed. In summary, the movable coating valve provided in this embodiment can independently drive the spray head 20 to pitch and rotate while maintaining the unobstructed glue flow path between the dispensing hole 31 and the spray head 20, resulting in rapid adjustment and reducing the space required for pitch movement.
[0048] For example, please refer to Figure 4 and Figure 5The glue spray head 20 includes a movable block 21, a mounting cylinder 22, and a glue spray nozzle 23. The movable block 21 includes a sleeve part 211 and a mounting part 212. The sleeve part 211 is sleeved on the outside of the adapter shaft 40. The through hole of the sleeve part 211 and the adapter shaft 40 form an inner cavity that communicates with the second flow channel 41. The mounting part 212 is provided with a plug hole 2121. The movable block 21 is provided with a connecting hole 2101. The connecting hole 2101 connects the inner cavity and the plug hole 2121. The mounting cylinder 22 is inserted into the plug hole 2121. The glue spray nozzle 23 is embedded in the outer end of the mounting cylinder 22. The glue spray nozzle 23 communicates with the plug hole 2121 through the mounting hole 221 of the mounting cylinder 22. During operation, the adhesive flowing out through the second flow channel 41 flows sequentially through the inner cavity, the connecting hole 2101, the insertion hole 2121, and the mounting hole 221, finally flowing to the spray nozzle 23 and being sprayed out under pressure. When process requirements change and the coating shape, range, etc., need to be adjusted accordingly, the user can remove and replace the mounting cylinder 22 and the spray nozzle 23 separately, which is highly adaptable and easy to operate.
[0049] For example, please refer to Figure 4 The adhesive spraying assembly also includes a third sealing ring 53, which is fitted over the mounting cylinder 22 and abuts against the wall of the insertion hole 2121 to seal the gap between the mounting cylinder 22 and the insertion hole 2121, preventing adhesive leakage. Because the seal between the mounting cylinder 22 and the insertion hole 2121 is a static seal, it offers high reliability, minimal wear, extended service life, reduced replacement frequency, and lower operating costs.
[0050] For example, please refer to Figure 7 The outer wall of the adapter shaft 40 is provided with an outer ring groove 42 extending around it. The glue outlet end of the second flow channel 41 extends to the bottom of the outer ring groove 42, so that the outer ring groove 42 is connected to the second flow channel 41. The hole wall of the sleeve part 211 and the outer ring groove 42 enclose the inner cavity to form an inner cavity. The structure and size of the inner cavity can be directly controlled by machining on the adapter shaft 40 and adjusting the structure and size of the outer ring groove 42. The manufacturing process is simple and conducive to cost control.
[0051] For example, please refer to Figure 3 and Figure 4 The adhesive spraying assembly also includes a first sealing ring 51, which is fitted around the outer periphery of the adapter 30 and abuts against the inner wall of the flow channel pipe 10 to seal the gap between the adapter 30 and the flow channel pipe 10. The seal between the flow channel pipe 10 and the adapter 30 is a static seal with high reliability. Compared with a dynamic seal, the first sealing ring 51 experiences less wear, which can extend its service life, reduce the frequency of replacement, and save on operating costs.
[0052] For example, please refer to Figure 3 and Figure 6The adhesive spraying assembly also includes a second sealing ring 52, which is fitted around the outer periphery of the adapter shaft 40. The adapter 30 has a connecting hole 34 through which the adapter shaft 40 passes. The second sealing ring 52 abuts against the inner wall of the connecting hole 34 to seal the gap between the adapter shaft 40 and the adapter 30, preventing adhesive from leaking out from the inner cavity and the interface between the first flow channel 32 and the second flow channel 41. The seal between the adapter 30 and the adapter shaft 40 is a static seal, which has high sealing reliability. Compared with a dynamic seal, the second sealing ring 52 experiences less wear, extending its service life, reducing replacement frequency, and saving operating costs.
[0053] Specifically, please refer to Figure 6 The adapter 30 includes a plug-in portion 301, a first hinge portion 302, and a second hinge portion 303. The first hinge portion 302 and the second hinge portion 303 are arranged side by side with a gap between them. The plug-in portion 301 is inserted into the lower end of the flow channel tube 10. The first hinge portion 302 and the second hinge portion 303 are respectively provided with coaxially arranged connecting holes 34. The first end of the adapter shaft 40 is connected to the first hinge portion 302, and the second end of the adapter shaft 40 is connected to the second hinge portion 303. The first sealing ring 51 is sleeved on the outer periphery of the plug-in portion 301, and the sleeve portion 211 is located between the first hinge portion 302 and the second hinge portion 303. By setting the first hinge portion 302 and the second hinge portion 303, the installation reliability between the adapter 30 and the adapter shaft 40 can be improved, and the glue spray head 20 can be limited, thereby improving the stability of the rotational connection between the adapter 30 and the glue spray head 20.
[0054] For example, please refer to Figure 3 , Figure 5 and Figure 6 The first flow channel 32 passes through the insertion part 301 and the first hinge part 302. The first hinge part 302 is provided with a glue dispensing groove 33 opposite to the end of the first end of the adapter shaft 40. The first flow channel 32 communicates with the glue dispensing groove 33. The glue inlet end of the second flow channel 41 passes through the end of the first end of the adapter shaft 40 and communicates with the glue dispensing groove 33. The second sealing ring 52 is sleeved on the outer periphery of the first end of the adapter shaft 40. The glue flowing out of the glue dispensing hole 31 flows through the first flow channel 32 to the glue dispensing groove 33. The glue dispensing groove 33 is sealed by the second sealing ring 52. The glue in the glue dispensing groove 33 then flows into the second flow channel 41 and then flows through the inner cavity to the glue spray head 20. A fastening pin 54 is provided at the end of the second end of the adapter shaft 40. The fastening pin 54 is snapped or screwed into the second hinge part 303 to lock the adapter shaft 40 in the installation position and also to maintain the installation position of the second sealing ring 52.
[0055] Specifically, please refer to Figure 5 and Figure 6The first flow channel 32 includes a first horizontal section 321 and a first vertical section 322 connected together. The second flow channel 41 includes a second horizontal section 411 and a second vertical section 412 connected together. The glue inlet end of the first horizontal section 321 is connected to the glue outlet 31, and the glue outlet end of the first vertical section 322 is connected to the glue outlet groove 33. The second horizontal section 411 passes through the end of the first end of the adapter shaft 40 and is connected to the glue outlet groove 33. The second vertical section 412 is connected to the glue inlet end of the spray head 20. The first flow channel 32 and the second flow channel 41 in this embodiment have simple structures and fewer bends in the flow path, which can make the glue outlet smoother and facilitate drilling, reducing processing difficulty and cost.
[0056] In some embodiments, a sliding sleeve can be installed inside the sleeve portion 211. The sliding sleeve is fixed to the central through hole of the sleeve portion 211, and a flow channel hole is formed on the sliding sleeve, penetrating its inner and outer walls. The inner end of the flow channel hole is connected to the glue outlet groove 33, and the outer end of the flow channel hole is connected to the connecting hole 2101. The addition of the sliding sleeve can reduce the friction between the glue spray head 20 and the adapter shaft 40, making the wear between them smaller and the rotation smoother.
[0057] For example, please refer to Figure 1 , Figure 2 and Figure 4 The spray nozzle 20 is equipped with an adapter 24, which is located on the outer wall of the movable block 21. The first adjustment mechanism includes a first power component, a sliding rotating block 130, and a connecting rod 140. The sliding rotating block 130 is sleeved on the outside of the flow channel tube 10. The first power component is driven to drive the sliding rotating block 130 to slide along the flow channel tube 10. One end of the connecting rod 140 is rotatably connected to the sliding rotating block 130, and the other end is rotatably connected to the adapter 24. The flow channel tube 10, the sliding rotating block 130, the connecting rod 140, and the spray nozzle 20 form a four-bar linkage. The output end of the first power component can extend and retract in the vertical direction, thereby driving the sliding rotating block 130 to slide relative to the flow channel tube 10, which in turn drives the connecting rod 140 to rotate while sliding. The spray nozzle 20 then tilts and rotates around the horizontal axis. The tilt adjustment of the spray nozzle 20 is stable and controllable.
[0058] For example, the adapter 24 is located on the outer side of the spray head 20 through which its pitch and rotation path passes. The output end of the first adjustment mechanism is connected to the adapter 24, and the first adjustment mechanism can adjust the pitch angle of the spray head 20. Specifically, the spray head 20 is connected to the output end of the first adjustment mechanism through the adapter 24. The adapter 24 is located on the outer side of the spray head 20 through which its pitch and rotation path passes. Compared with the conventional setting of setting the adapter 24 on the rotation axis of the spray head 20, the torque required to drive the spray head 20 to rotate is smaller, and the adapter 24 does not need to be penetrated by the rotation axis. That is, the adapter 24 does not need to be set at the end of the spray head 20 through which its rotation axis passes. The adapter 24 can be set on the side of the rotation axis. Since the position of the adapter 24 is in the area that the spray head 20 needs to pass through when pitching, the adapter 24 does not occupy additional space. Therefore, the space occupied by the movable coating valve in the horizontal direction is smaller, reducing the risk of the movable coating valve interfering with or colliding with other objects during operation.
[0059] For example, the adapter 24 and the movable block 21 are integrally formed, which simplifies the production process and reduces manufacturing costs.
[0060] For example, please refer to Figures 1-4 , Figure 8 The first power assembly includes a first rotary drive 110, a transmission nut, and a transmission screw 120. The first rotary drive 110 is a rotary servo motor, with its output end vertically aligned and connected to the transmission nut. The transmission screw 120 extends in the same direction as the flow channel pipe 10. The transmission nut is threaded onto the transmission screw 120, which is connected to the sliding rotating block 130. The power combination of the rotary servo motor, transmission nut, and transmission screw 120 can output stable and high-precision linear power. The use of a rotary servo motor in the first rotary drive 110 allows for a more compact and aesthetically pleasing overall layout of the movable coating valve.
[0061] Of course, in other embodiments of this utility model, the first rotary drive 110 may also be a rotary motor or other drive element that can output rotary power, and the first power assembly may also be a linear electric actuator or other drive element that can output linear power.
[0062] For example, please refer to Figures 1-4 , Figure 8The first adjustment mechanism also includes a lever 150, and the transmission screw 120 is connected to the sliding rotating block 130 via the lever 150. Specifically, the sliding rotating block 130 is provided with an annular groove 131 extending along its circumference. One end of the lever 150 is connected to the output end of the first power component, and the other end of the lever 150 is provided with a fork portion, which is inserted into the annular groove 131. When the second adjustment mechanism drives the flow channel pipe 10 to rotate around the vertical axis, the sliding rotating block 130 rotates synchronously. The annular groove 131 allows the lever 150 to remain in its original position while preventing the lever 150 from disengaging from the sliding rotating block 130, thus providing good compatibility.
[0063] For example, the fork portion is provided with a concave arc surface on the side facing the sliding rotating block 130. The arc surface is adapted to the inner wall of the annular groove 131. The lever 150 can abut against the inner wall of the annular groove 131 through the arc surface, thereby improving the stability of the assembly and the smoothness of the flow channel tube 10 rotating around the vertical axis.
[0064] Specifically, please refer to Figures 1-4 , Figure 8 A hinge seat 132 is integrally formed on the sliding rotating block 130. The hinge seat 132 is located at the lower end of the sliding rotating block 130. One end of the connecting rod 140 is rotatably connected to the hinge seat 132 via a first rotating shaft around a horizontal axis, and the other end of the connecting rod 140 is rotatably connected to the adapter seat 24 via a second rotating shaft around a horizontal axis. The integral forming of the hinge seat 132 and the sliding rotating block 130 can reduce production costs. The first and second rotating shafts can be quickly installed via spring clips, resulting in high assembly efficiency and easy replacement. The hinge seat 132 on the sliding rotating block 130 and the adapter seat 24 of the spray nozzle 20 are located on the same side of the flow channel tube 10. The pitch adjustment range of the spray nozzle 20 can reach 0° to 90°, that is, the pitch orientation of the spray nozzle 20 can be steplessly adjusted between vertically downward and horizontally.
[0065] For example, a guide groove 11 is provided on one of the sliding rotating block 130 and the flow channel tube 10, and a guide pin 60 is provided on the other. The guide groove 11 is a long groove-shaped structure, extending in the same direction as the flow channel tube 10, and the guide pin 60 is inserted into the guide groove 11. In this embodiment, please refer to... Figure 8 The outer wall of the flow channel 10 is provided with a guide groove 11, and the sliding rotating block 130 is provided with a mounting hole 221. The guide pin 60 is installed through the mounting hole 221, with one end extending into the guide groove 11. The width of the guide groove 11 is equal to the outer diameter of the guide pin 60, thereby restricting the relative rotation of the sliding rotating block 130 and ensuring good structural stability.
[0066] For example, please refer to Figure 3 , Figure 4 and Figure 8The sliding rotating block 130 includes an upper stop 1301 and a lower stop 1302. The lower stop 1302 is sleeved on the upper stop 1301. The upper end of the upper stop 1301 is provided with an upper flange that extends circumferentially and protrudes outward. An annular groove 131 is formed between the upper flange and the main body of the lower stop 1302. A hinge seat 132 is formed on the lower stop 1302. The upper stop 1301 is provided with a fastening hole 13011, and the lower stop 1302 is provided with a corresponding oblong hole 13021. The upper stop 1301 and the lower stop 1302 are connected by a fastening screw that passes through the oblong hole 13021 and connects to the fastening hole 13011.
[0067] In some embodiments, the upper stop 1301 and the lower stop 1302 can be movably connected by an elastic element such as a spring. The upper stop 1301 is fixed outside the flow channel tube 10. The first rotary drive member 110 can drive the lower stop 1302 to move downward by the lever 150. At this time, the elastic element is compressed. When the first rotary drive member 110 drives the lever 150 to rise, the elastic element drives the lower stop 1302 to rise and reset, which can also realize the pitch adjustment of the glue spray head 20.
[0068] For example, the output end of the second adjustment mechanism is connected to the flow channel tube 10 via a transmission connection. The second adjustment mechanism can drive the flow channel tube 10 to rotate around its axis to achieve horizontal adjustment of the adhesive spraying direction. Specifically, please refer to... Figure 1 and Figure 2 The second adjustment mechanism includes a second rotary drive component 210 and a belt drive assembly. The belt drive assembly includes a first synchronous pulley 221, a second synchronous pulley 222, and a synchronous belt 223. The first synchronous pulley 221 is connected to the output end of the second rotary drive component 210, the second synchronous pulley 222 is fixedly sleeved on the outer wall of the flow channel tube 10, and the synchronous belt 223 is tightly sleeved on the first synchronous pulley 221 and the second synchronous pulley 222. Using a belt drive assembly as the transmission structure ensures accurate and stable transmission, high transmission efficiency, and convenient adjustment. During operation, the second rotary drive component 210 drives the first synchronous pulley 221 to rotate, and the rotational power is transferred to the flow channel tube 10 via the synchronous belt 223 and the second synchronous pulley 222, causing the flow channel tube 10 and the spray nozzle 20 to rotate around the vertical axis. The rotation angle range is 0 to 360°, meaning the horizontal orientation of the spray nozzle 20 can be steplessly adjusted within a 360° range.
[0069] For example, the second rotary drive 210 adopts a rotary servo motor, please refer to Figure 1 and Figure 2 The first rotary drive 110 and the second rotary drive 210 are arranged side by side on one side of the valve body assembly, and the high-speed solenoid valve 400 is arranged side by side on the other side of the valve body assembly opposite to it. The overall layout of the movable coated valve is compact and beautiful.
[0070] Of course, in other embodiments of this utility model, the second rotary drive 210210 may also be a rotary motor or other drive element that can output rotary power.
[0071] For example, please refer to Figure 2 The belt drive assembly also includes a tension pulley 224, which is rotatably mounted on the body of the first rotary drive 110 or the second rotary drive 210. The tension pulley 224 presses against the outer side of the synchronous belt 223 to keep the synchronous belt 223 in a taut state and improve transmission stability.
[0072] For example, please refer to Figures 1-4 The valve body assembly includes a linear motor 310 and a valve stem 320. The valve stem 320 passes through the flow channel tube 10, and its upper end is connected to the output end of the linear motor 310. A tapered portion 3201 is provided at the lower end of the valve stem 320. The linear motor 310 can drive the valve stem 320 to slide along the flow channel tube 10 to adjust the opening and closing size of the dispensing hole 31. The tapered portion 3201 can selectively block the dispensing hole 31. Specifically, the linear motor 310 is a linear servo motor, which can precisely control the length of the valve stem 320 extending into the dispensing hole 31, thereby precisely controlling the opening and closing size of the dispensing hole 31 and accurately adjusting the dispensing rate.
