DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0031] The core of the present invention is to provide an Io-Link monitoring device, which can adjust the detection accuracy to adapt to mechanisms with different requirements.

[0032] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0033] The present application provides an Io-Link monitoring device, comprising: a sensor housing 10, a cross-section adjustment mechanism, a pressure adjustment mechanism and an optical adjustment mechanism;

[0034] The sensor housing 10 is a hollow structure, and a fluid inlet and a fluid outlet are provided on the sensor housing 10;

[0035] The cross-section adjustment mechanism is disposed at the fluid inlet in the sensor housing 10, and the cross-section adjustment mechanism is used to adjust the flow detection area;

[0036] The pressure regulating mechanism is disposed in the sensor housing 10, and the pressure regulating mechanism is used to adjust the triggering pressure of the cross-section regulating mechanism;

[0037] The optical adjustment mechanism is arranged on the pressure adjustment mechanism, and the optical adjustment mechanism is used to adjust the intensity of light entering the sensor housing 10 .

[0038] Specifically, the sensor housing 10 is an L-shaped structure, and its two ends are respectively a fluid inlet and a fluid outlet. The fluid generally enters the sensor housing 10 from the fluid inlet and flows out of the sensor housing 10 from the fluid outlet. A cross-section adjustment mechanism is provided between the fluid inlet and the fluid outlet. The cross-section adjustment mechanism can adjust the distance between it and the inner wall of the sensor housing 10. In extreme cases, when the cross-section adjustment mechanism is completely in contact with the inner wall of the sensor housing 10, the fluid cannot flow from the fluid inlet to the fluid outlet. When the distance between the cross-section adjustment mechanism and the inner wall of the sensor housing 10 gradually increases, the flow detection area can be gradually increased. Conversely, In order to adjust the flow detection area, a pressure adjustment mechanism is further provided in the sensor housing 10, and the pressure adjustment mechanism is connected to the cross-section adjustment mechanism. The trigger pressure of the cross-section adjustment mechanism can be adjusted through the pressure adjustment mechanism, so as to further improve the detection range. An optical adjustment mechanism is provided on the pressure adjustment mechanism, and the optical adjustment mechanism can adjust the intensity of light irradiated into the sensor housing 10, so as to have a more sensitive detection progress under smaller triggering conditions. Through the coordinated action of the cross-section adjustment mechanism, the pressure adjustment mechanism and the optical adjustment mechanism, the monitoring equipment of the present application can adjust the detection accuracy to adapt to mechanisms with different requirements.

[0039] On the basis of the above embodiment, the cross-section adjustment mechanism includes a baffle 14, a driven rod 15, an adjusting connecting rod 16, a hinge block 17, a baffle ring 18, a central spindle 19, an adjusting shaft sleeve 20 and a short rod 35. The baffle 14 is provided with multiple ones and all are arranged between the fluid inlet and the fluid outlet. The baffle ring 18 is fixedly connected to the baffle 14 and sleeved on the short rod 35. The short rod 35 is fixedly connected to the driven rod 15. The driven rod 15 is rotatably connected to the central spindle 19. The hinge block 17 is sleeved on the driven rod 15. The two ends of the adjusting connecting rod 16 are rotatably connected to the hinge block 17 and the adjusting shaft sleeve 20 respectively. The adjusting shaft sleeve 20 is sleeved on the central spindle 19.

[0040] Specifically, the main body of the cross-section adjustment mechanism that limits the flow of fluid from the fluid inlet to the fluid outlet is the baffle 14, the baffle 14 is fixedly connected to the baffle ring 18, the baffle ring 18 is rotatably connected to the short rod 35, the short rod 35 is rotatably connected to the driven rod 15, the driven rod 15 is rotatably connected to the central spindle 19, and a hinge block 17 is provided on the driven rod 15. The hinge block 17 is an annular structure and can slide along the driven rod 15. The hinge block 17 is rotatably connected to the adjusting link 16, and the other end of the adjusting link 16 is rotatably connected to the adjusting shaft sleeve 20. The adjusting shaft sleeve 20 is sleeved on the outer periphery of the central spindle 19. It should be noted that the central spindle 19 should be regarded as stationary relative to the sensor housing 10 when the pressure adjustment mechanism is not considered. Please refer to the attached Figure 3 To Attachment Figure 6 When the adjusting sleeve 20 slides upward along the central spindle 19, the adjusting connecting rod 16 will rotate toward the central spindle 19 to reduce the angle between the two. Correspondingly, the hinge block 17 will move along the driven rod 15 toward the central spindle 19. Since the driven rod 15 is rotationally connected to the central spindle 19, and the baffle ring 18 is fixedly connected to the baffle 14, the baffle 14 and the driven rod 15 are synchronously deflected during the upward movement of the adjusting connecting rod 16, thereby increasing the distance between the baffle 14 and the inner wall of the sensor housing 10 and increasing the flow detection area. Conversely, the distance between the baffle 14 and the inner wall of the sensor housing 10 can be reduced to reduce the flow detection area.

[0041] On the basis of the above embodiment, a plurality of protrusions with through holes are evenly distributed along the circumference of the central spindle 19, a plurality of follower rods 15 are provided, a U-shaped connecting block is provided at the end of the follower rod 15 and is hinged to the protrusions through the connecting block, the baffle 14 is a fan-shaped structure, and the two radii of each baffle 14 are fixedly connected to two adjacent baffle rings 18.

[0042] For details, please refer to the attached Figure 3 To Attachment Figure 6 At the same horizontal position of the lower end of the central spindle 19, a plurality of protrusions are evenly distributed in the circumferential direction, the driven rod 15 is hinged to the protrusions, the number of baffles 14 is preferably eight, and the eight baffles and the driven rod 15 can be combined into a circular surface. When the baffle 14 is perpendicular to the central spindle, the cross-section adjustment mechanism can completely isolate the fluid inlet and the fluid outlet.

[0043] On the basis of the above embodiment, the cross-section adjustment mechanism also includes a lower fixed plate 13 and an adjustment dial 21. The lower fixed plate 13 is fixed to the inside of the sensor housing 10. The lower fixed plate 13 is a circular plate and has a through hole in the center. The adjustment sleeve 20 passes through the through hole. The adjustment dial 21 is arranged on the side of the lower fixed plate 13 away from the baffle 14, and the central spindle 19 is threadedly connected to the adjustment dial 21.

[0044] Specifically, a through hole is provided at the center of the lower fixed plate 13 and is fixed inside the sensor housing 10. The adjusting sleeve 20 passes through the through hole, and the adjusting sleeve 20 can reciprocate up and down in the through hole. An adjusting dial 21 is provided on the side of the lower fixed plate 13 away from the baffle 14. The adjusting dial 21 is threadedly connected to the central spindle 19. When the adjusting dial 21 rotates, it can drive the adjusting sleeve 20 to move up and down in the vertical direction. When the adjusting sleeve 20 moves up, it can drive the baffles 14 to move together. When it moves down, it can drive the baffles 14 to expand until multiple baffles 14 are in the same plane.

[0045] On the basis of the above embodiment, a through hole is provided on the sensor housing 10, and a cross-section adjustment knob 11 which can rotate relative to the sensor housing 10 is provided at the through hole. The cross-section adjustment knob 11 is an annular structure, and a plurality of blocks are evenly distributed on the inner wall of the cross-section adjustment knob 11. The outer periphery of the adjustment dial 21 is provided with notches matching the blocks, and the adjustment dial 21 is fixedly connected to the adjustment sleeve 20.

[0046] For details, please refer to the attached Figure 6 A through hole is provided at the upper end of the sensor housing 10, and a lower fixing plate 13 is provided at the through hole. A cross-section adjusting knob 11 is also provided at the through hole. The cross-section adjusting knob 11 is an annular structure, and a plurality of blocks extending in the vertical direction are provided on its inner periphery. An adjusting dial 21 is also provided in the cross-section adjusting knob 11, and the adjusting dial 21 is engaged with the plurality of blocks. When the cross-section adjusting knob 11 is rotated, the adjusting sleeve 20 can be driven to rotate synchronously. Since the adjusting sleeve 20 is threadedly connected to the central spindle 19, the adjusting sleeve 20 can move upward or downward relative to the central spindle 19 when it rotates.

[0047] On this basis, the principle and use process of the cross-section adjustment mechanism are as follows: when it is necessary to adjust the opening degree of the baffle 14 according to different flow rates, the cross-section adjustment knob 11 can be rotated, and the rotation of the cross-section adjustment knob 11 will drive the adjustment dial 21 to rotate through the block through the notch, and the rotation of the adjustment dial 21 will drive the adjustment sleeve 20 to move up under the drive of the thread, and the upward movement of the adjustment sleeve 20 will pull the hinge block 17 through the adjustment connecting rod 16 to make the short rod 35 drive the baffle ring 18 to make the baffle 14 rotate and fold around the driven rod 15. In this process, since the baffle 14 is made of hard material and the driven rod 15 is adjusted due to the baffles 14 on both sides The connecting rod 16 rotates inwardly under the pull, thereby also driving the driven rod 15 to rotate at an angle with the hinge point of the central spindle 19 as the axis, thereby achieving the purpose of changing the cross-sectional area of ​​the fluid inlet. Conversely, when the adjustment dial 21 moves downward, the movement laws of the hinge block 17, the baffle 14 and the driven rod 15 are completely opposite. In this way, better detection can be achieved under different flow rates. Moreover, since the equipment adopts a new communication protocol, the relevant data of the sensor can be delivered to the controller, so that the controller can correspond the fluid flow conditions under the measurement results under different cross-sections to the results, thereby achieving accurate measurement.

[0048] On the basis of the above embodiment, the pressure regulating mechanism includes a connecting frame 12, an elastic member 22, an upper fixed plate 23, a pressure regulating plate 24, a pressure regulating rod 31, a main push rod 32, and a fixed block 36. The fixed block 36 is arranged on the side of the cross-section adjustment knob 11 away from the sensor housing 10. The fixed block 36 is fixedly connected to the sensor housing 10 through the connecting frame 12. The upper fixed plate 23 is arranged in the fixed block 36. The fixed block 36 is provided with a notch. The pressure regulating plate 24 is provided with an extension extending from the notch to the outside of the fixed block 36. The elastic member 22 is arranged between the pressure regulating plate 24 and the upper fixed plate 23. The pressure regulating plate 24 is connected to the fixed block 36 through the pressure regulating rod 31. The main push rod 32 passes through the upper fixed plate 23 and is fixedly connected to the pressure regulating plate 24 and the central spindle 19.

[0049] Specifically, the upper end of the central spindle 19 is fixedly connected to the main push rod 32, the main push rod 32 is fixedly connected to the pressure regulating plate 24, the main push rod 32 passes through the upper fixed plate 23, the pressure regulating plate 24 is fixedly connected to the fixed block 36 through the pressure regulating rod 31, and the distance between the pressure regulating plate 24 and the upper fixed plate 23 can be adjusted by adjusting the length of the pressure regulating rod 31 extending out of the fixed block 36. Since an elastic member 22 is provided between the pressure regulating plate 24 and the upper fixed plate 23, when the pressure regulating plate 24 moves downward, the elastic force of the elastic member 22 can be adjusted, thereby achieving the purpose of adjusting the trigger pressure of the cross-section adjustment mechanism.

[0050] Based on the above embodiment, the pressure regulating rod 31 is a threaded rod, the pressure regulating rod 31 is rotatably connected to the pressure regulating plate 24, the pressure regulating rod 31 is threadedly connected to the fixed block 36, the elastic member 22 is a pressure spring, and the elastic member 22 is always in a compressed state.

[0051] Specifically, the pressure regulating rod 31 is a threaded rod, and the upper end of the pressure regulating rod 31 is rotatably connected to the pressure regulating plate. A threaded hole is provided on the fixing block 36, and a thread is provided on the lower end of the pressure regulating rod 31. When it is necessary to adjust the triggering pressure of the cross-section regulating mechanism when measuring the flow rate, the pressure regulating rod 31 can be screwed by a tool. The rotation of the pressure regulating rod 31 will drive the pressure regulating plate 24 to move in the up and down directions. Since the pressure regulating plate 24 is fixedly connected to the main push rod 32, and the main push rod 32 is fixedly connected to the central spindle 19, when the cross-section regulating mechanism is pushed, the main push rod 32 will be driven to move in the up and down directions through the central spindle 19. Adjusting the pressure regulating plate 24 can adjust the elastic force of the elastic member 22, thereby achieving the purpose of adjusting the triggering pressure of the cross-section regulating mechanism. The cross-sectional area of ​​the elastic member 22 at different lengths is matched with different cross-sectional regulating mechanisms, and the flow rate represented by the measured data is also different. Since the equipment adopts a new communication protocol, it can pass the relevant data of the sensor to the controller. Therefore, it can also exchange data with the controller in time in different states of the sensor, thereby ensuring the accuracy of the detection.

[0052] On the basis of the above-mentioned embodiment, the optical adjustment mechanism includes an angle adjustment knob 25, a light-transmitting rod 26, a shading plate 27, a light-shielding outer shell frame 28, an angle adjustment screw 29, an auxiliary connecting rod 30, an auxiliary plate 33 and an extension rod 34. The light-shielding outer shell frame 28 is arranged in a fixed block 36. The angle adjustment screw 29 penetrates the light-shielding outer shell frame 28 and can reciprocate in the axial direction of the central spindle 19. The two ends of the angle adjustment screw 29 are respectively connected to the light-transmitting rod 26 and the extension rod 34. The extension rod 34 is slidably connected to the auxiliary plate 33. The two ends of the light-shielding plate 27 are respectively rotatably connected to the light-shielding outer shell frame 28 and the auxiliary connecting rod 30. The auxiliary connecting rod 30 is rotatably connected to the light-transmitting rod 26.

[0053] Specifically, when the opening angle of the shading plate 27 needs to be adjusted, the angle adjustment knob 25 can be turned to make the auxiliary plate 33 drive the extension rod 34 to rotate, and then the angle adjustment screw 29 drives the light-transmitting rod 26 to move up and down under the action of threaded cooperation, so that the auxiliary connecting rod 30 drives the shading plate 27 to rotate to close or open. When the main push rod 32 pushes the shading outer shell frame 28 to move it, the light emitted by the light emitting component will be blocked by the shading plate 27 and then received by the photoelectric sensing component, and an electrical signal will be generated. When the angle between the shading plates 27 increases, the same moving distance of the shading outer shell frame 28 can transmit more light signals and generate stronger electrical signals, so that even slight movements can be accurately measured, further improving the measurement accuracy.

[0054] On the basis of the above embodiment, two grooves are provided in the fixing block 36, the light shielding outer shell frame 28 is a U-shaped structure, and the two ends of the light shielding outer shell frame 28 are respectively engaged in the two grooves.

[0055] Specifically, a groove is provided on the inner peripheral side wall of the fixing block 36 , and the two ends of the light shielding outer shell frame 28 are parallel to each other and are respectively disposed in two grooves to prevent the light shielding outer shell frame 28 from rotating in the horizontal direction.

[0056] On the basis of the above-mentioned embodiment, the angle adjustment screw rod 29 is a threaded rod and is threadedly connected to the shading outer housing frame 28 , and two shading plates 27 and two auxiliary connecting rods 30 are provided.

[0057] Specifically, the angle adjustment screw 29 is connected to the auxiliary plate 33, and the auxiliary plate 33 is fixedly connected to the angle adjustment knob 25. Rotating the angle adjustment knob 25 will cause the auxiliary plate 33 to drive the extension rod 34 to rotate, and further drive the light-transmitting rod 26 to move in the up and down directions.
