[0029] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.
[0030] like Figure 1As shown, the waterproof photocell device in this embodiment includes a protective component, a waterproof cover 30, a sensor 40, an air intake structure, and an adjustment component 60. Specifically, the photocell cable passes through the protective component and extends into the waterproof cover 30. The photocell is placed inside the waterproof cover 30, and the photocell and the photocell cable are connected inside the waterproof cover 30. This ensures that the photocell assembly composed of the photocell cable and the photocell is effectively protected, preventing cleaning liquid from splashing onto the photocell assembly during the cleaning process, which could cause corrosion, short circuits, or damage to the photocell assembly.
[0031] Optionally, in this embodiment, the waterproof cover 30 and the protective component are detachably connected, and the adjusting component 60 is connected to the waterproof cover 30. Thus, the protective component and the waterproof cover 30 can protect the photoelectric sensor and the photoelectric sensor respectively. Furthermore, the position of the waterproof cover 30 and the protective component can be adjusted by the adjusting component 60 to suit photoelectric sensor components in different locations, achieving a variable position effect and expanding its applicability. Further, the sensor 40 and the air intake structure are both located at the waterproof cover 30 to ensure that the air pressure inside the waterproof cover 30 is always positive, preventing water from entering. This creates a dry space inside the protective component and the waterproof cover 30 that is isolated from the outside environment, ensuring the dryness of the photoelectric sensor component.
[0032] Specifically, in this embodiment, the protective component includes a locking member 10 and a waterproof tube 20. The photocell cable passes through the locking member 10 and the waterproof tube 20 in sequence and then extends into the waterproof cover 30. The locking member 10 ensures the stable installation of the photocell cable within the waterproof tube 20, and the waterproof tube 20 provides effective protection for the photocell cable. Specifically, the locking member 10 and the waterproof tube 20 are detachably connected. In this embodiment, a screw connection is used; other methods may be used in other embodiments, and this is not limited here. Specifically, in this embodiment, the locking member 10 is provided with internal threads, which ensures a closer fit between the locking member 10 and the waterproof tube 20, preventing liquid ingress.
[0033] Furthermore, the locking member 10 is provided with an inlet hole 101, and the waterproof tube 20 is provided with a flared hole 201. The cross-sectional area of the flared hole 201 gradually decreases from the direction close to the locking member 10 to the direction far away from the locking member 10. This ensures that the photoelectric sensor wire can pass smoothly through the inlet hole 101 and the flared hole 201 in sequence. With the gradually decreasing cross-sectional area of the flared hole 201, the air pressure is effectively increased under the condition of constant space and air pressure, thereby preventing water from entering. Specifically, the inner wall of the flared hole 201 is a smooth bevel, which not only guides the photoelectric sensor wire but also effectively prevents water from entering.
[0034] Optionally, one of the waterproof pipe 20 and the waterproof cover 30 is provided with a first mounting plate 21, and the other is provided with a second mounting plate 31. The first mounting plate 21 and the second mounting plate 31 are connected by screws to ensure a stable connection between the waterproof pipe 20 and the waterproof cover 30. Specifically, in this embodiment, a square first mounting plate 21 extends outward from the side of the waterproof pipe 20 away from the locking member 10, and a plurality of first mounting holes 211 are evenly arranged on the first mounting plate 21 to ensure stable installation with the waterproof cover 30.
[0035] Specifically, the waterproof cover 30 is provided with a guide portion and a receiving portion that are interconnected. A square second mounting plate 31 extends outward from the side of the guide portion near the waterproof pipe 20, and a plurality of second mounting holes 311 are evenly arranged on the second mounting plate 31. Specifically, the second mounting plate 31 is correspondingly provided with the first mounting plate 21, and the second mounting holes 311 are correspondingly provided with the first mounting holes 211. Thus, screws passing through the first mounting holes 211 and the second mounting holes 311 in sequence can stably connect the first mounting plate 21 and the second mounting plate 31, thereby achieving stable installation between the waterproof cover 30 and the waterproof pipe 20 and preventing water from entering the interior through the gap between the two and corroding the photocell assembly.
[0036] Furthermore, the cross-sectional area of the guide portion gradually increases from near to far from the protective component until it is the same as the cross-sectional area of the receiving portion, in order to prevent water from entering and effectively reduce the space occupied. For example, the protective component and the guide portion are positioned correspondingly and are both lower than the height of the receiving portion, thereby achieving an inclined arrangement of the top surface of the guide portion to prevent liquid from entering the interior of the waterproof cover 30.
[0037] Specifically, a connection port 301 is provided on the side of the guide portion facing the protective component. The photoelectric sensor cable passes through the inlet hole 101 and the horn hole 201 in sequence, and then passes through the connection port 301 to enter the interior of the waterproof cover 30. Specifically, the photoelectric sensor is placed in the receiving portion, and the photoelectric sensor cable can pass through the guide portion and connect to the photoelectric sensor, so that the photoelectric sensor component will not be damaged by water during the cleaning process, and can still operate.
[0038] like Figure 1 As shown, in this embodiment, a pull-out plate 32 is provided at the bottom of the waterproof cover 30. When the pull-out plate 32 is open, the photoelectric sensor can be inserted into the waterproof cover 30. When the pull-out plate 32 is closed, the interior of the waterproof cover 30 is a closed space to ensure a dry environment. Specifically, the pull-out plate 32 is slidably disposed in the waterproof cover 30 to ensure quick placement and position adjustment of the photoelectric sensor. In other embodiments, the position and opening / closing method of the pull-out plate 32 can also be set as needed, which will not be elaborated here.
[0039] Furthermore, a photoelectric sensor detection hole 302 is provided through the side of the waterproof cover 30 away from the protective assembly. The photoelectric sensor's beam can pass through the detection hole 302 to ensure the normal operation of the photoelectric sensor. Specifically, a sealing plate made of transparent material is used to seal the outside of the photoelectric sensor detection hole 302 to ensure that the photoelectric sensor can be effectively sealed while operating normally, thus forming a closed space inside the waterproof cover 30 and preventing water from entering. Optionally, the sealing plate can be made of high-purity inorganic glass to ensure the normal use of the photoelectric sensor while preventing liquid from entering.
[0040] For example, the outer surface of the waterproof cover 30 is coated with PTFE material to prevent chemicals from corroding the photocell waterproof device, so that the photocell assembly can be well protected in environments with water and chemicals and can work stably for a long time.
[0041] Optionally, in this embodiment, the sensor 40 is disposed at the top of the receiving portion and extends into the waterproof cover 30 to detect the internal air pressure of the waterproof cover 30. For example, the sensor 40 can detect whether the internal air pressure of the waterproof cover 30 is less than 0.1 bar. Further, the air intake structure is connected to the interior of the waterproof cover 30 and can blow air into the waterproof cover 30 based on the detection result of the sensor 40 to ensure that the interior of the waterproof cover 30 is always under positive pressure, preventing liquid from entering.
[0042] Specifically, the air intake structure includes a solenoid valve 50 and an air inlet 501. Correspondingly, a blowhole is provided through the top of the receiving portion of the waterproof cover 30, and the blowhole is connected to the air inlet 501. For example, when the sensor 40 detects that the pressure inside the waterproof cover 30 is less than 0.1 bar, the solenoid valve 50 can be opened via the PLC to ensure that the air inlet 501 can draw in air, which is then delivered to the waterproof cover 30 through the blowhole, thus maintaining a positive pressure environment inside the waterproof cover 30 and preventing water from entering. Conversely, when the sensor 40 detects that the pressure inside the waterproof cover 30 is greater than 0.1 bar, the solenoid valve 50 can be closed via the PLC to stop the air intake operation of the air inlet 501.
[0043] Optionally, in this embodiment, the adjustment component 60 is connected to the top of the receiving part. Specifically, one end of the adjustment component 60 is fixed to equipment such as a filling machine, and the other end is rotatably connected to the waterproof cover 30. In this way, the adjustment component 60 can achieve the adjustment effect of the waterproof cover 30 at different positions, so as to drive the protective component to move synchronously and protect the photoelectric sensor components at different positions, thus making it more widely applicable.
[0044] Specifically, the adjustment assembly 60 includes a fixing member 61, an adjusting rod 62, and a rotating member 63. Specifically, in this embodiment, the fixing member 61 is disposed at one end of the adjustment assembly 60 and is used to fix it above the gripper of the filling machine. The fixing member 61 has a universal adjustment function to expand the adjustment range. Further, multiple adjusting rods 62 are provided, and adjacent adjusting rods 62 are rotatably connected by the rotating member 63. Thus, by adjusting the position of the adjusting rod 62 and the rotation angle between adjacent adjusting rods 62, the position of the waterproof cover 30 can be moved, so that the waterproof cover 30 is in a suitable position to provide comprehensive protection for the photoelectric sensor.
[0045] Working principle: The photoelectric sensor wire is inserted through the inlet hole 101 and extends out of the first mounting plate 21 through the horn hole 201; the photoelectric sensor is placed inside the waterproof cover 30 and connected to the photoelectric sensor wire; then the first mounting plate 21 and the second mounting plate 31 are aligned and fixed with screws; then the pull-out plate 32 is opened to allow the photoelectric sensor to be installed in its original position and the photoelectric sensor beam to pass through the photoelectric sensor detection hole 302; then the pull-out plate 32 is closed; the position and rotation angle of the adjusting rod 62 are adjusted to adjust the position of the waterproof cover 30 and the protective components to complete the protective operation of the photoelectric sensor assembly.
[0046] In summary, the waterproof device for photoelectric sensors in this embodiment can effectively reduce cost losses caused by short circuits and other problems during the cleaning process of photoelectric sensor components, and effectively improve production efficiency. At the same time, the waterproof device for photoelectric sensors in this embodiment has a simple structure, is easy to operate, and has a low cost.
