[0024] In the accompanying drawings, the same parts are referred to by the same reference numerals, and the drawings are not to scale. Detailed Implementation
[0025] To clearly illustrate the invention, the following description is provided in conjunction with embodiments.
[0026] In the description of this invention, it should be noted that the terms "upper," "lower," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used merely for the convenience of describing the invention and for 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 the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] like Figures 1-3 As shown, the present invention provides an oiling system comprising: an oil control device 1, an oil storage device 2, and an oil outlet device 3 connected in sequence; the oil control device 1 is used to control the oil storage device 2 to discharge silicone grease, the oil storage device 2 is used to deliver silicone grease to the oil outlet device 3, and the oil outlet device 3 is used to output silicone grease and coat it on the end shaft of the air guide plate (not shown in the figure).
[0028] In this invention, the silicone grease to be applied to the air conditioner guide plate is stored in the oil storage device 2. The oil control device 1 is connected upstream of the oil storage device 2. It mainly squeezes out the silicone grease in the oil storage device 2 by filling the oil storage device 2 with gas, and then transports the squeezed silicone grease to the oil outlet device 3. The silicone grease is output on the oil outlet device 3, and the operator's oiling operation makes the silicone grease evenly coated on the end shaft of the air guide plate.
[0029] The output of silicone grease is controlled by the air supply process from the oil control device 1 to the oil storage device 2. Specifically, the output of silicone grease from the oil storage device 2 to the oil outlet device 3 and the interval between air outlets are controlled by controlling the air pressure, the interval between air outlets, and the duration of each air outlet.
[0030] By controlling the amount of oil produced by the oil control device 1, the problem of uneven application of silicone grease during production is solved. This ensures the consistency of silicone grease application on the air guide plate, effectively guaranteeing product quality while ensuring the production process.
[0031] The connection between the oil storage device 2 and the oil outlet device 3 allows the silicone grease to be automatically transported from the oil storage device 2 to the oil outlet device 3 and then output from the oil outlet device 3. The operator only needs to hold the air guide plate to the oil outlet device 3 to complete the uniform coating of silicone grease on the end shaft, which effectively reduces the ineffective action of frequently picking up and putting down the oil brush, greatly reduces labor intensity, and significantly improves production efficiency.
[0032] In this invention, the oil control device 1, oil storage device 2, and oil outlet device 3 of the oiling system each include two sets corresponding to the end shafts at both ends of the air guide plate, wherein the oil storage device 2 and the oil outlet device 3 are connected to the frame 6.
[0033] Combination Figure 1 and Figure 3 In one embodiment, the oil control device 1 is placed at the bottom of the frame 6, and the oil storage device 2 and the oil outlet device 3 are both connected to the top of the frame 6. A hose-like air pipe 4 connects the oil control device 1 and the oil storage device 2. The oil control device 1 controls the discharge of silicone grease from the oil storage device 2 by inflating the oil storage device 2 with air.
[0034] In this embodiment, the gas source for the oil control device 1 is provided externally. After passing through the oil control device 1, the gas is injected into the oil storage device 2 via the gas pipe 4. During inflation, the oil output of the oil storage device 2 is controlled by controlling the amount of gas filling under set parameter conditions. Specifically, the oil output from the oil storage device 2 to the downstream oil outlet device 3 is controlled by adjusting the gas pressure and the duration of each gas outlet. The interval oil outlet time of the oil storage device 2 is controlled by adjusting the interval of the gas filling.
[0035] like Figure 4 As shown, and in combination Figures 2-3 The oil storage device 2 specifically includes an oil storage cylinder 21. Oil cylinder fixing seats 22 are provided on both sides of the top of the frame 6, and the two oil storage cylinders 21 are respectively fixedly installed on the oil cylinder fixing seats 22. Inside the oil storage cylinder 21, a piston 23 that can advance axially along the oil storage cylinder 21 is provided. An air pipe 4 is connected to the oil storage cylinder 21, specifically to the end of the piston 23 at its initial position. Gas enters the oil storage cylinder 21 through the air pipe 4, occupies the internal space of the oil storage cylinder 21, and pushes the piston 23 forward, squeezing out the silicone grease from the oil storage cylinder 21 and delivering it to the oil outlet 24 of the oil storage cylinder 21 to the oil outlet device 3. The oil storage cylinder 21 is made of transparent plastic, allowing for easy observation of the silicone grease's movement within the oil storage cylinder 21 and facilitating real-time monitoring of the remaining oil level in the oil storage cylinder 21.
[0036] To further automate the monitoring of the silicone grease level in the reservoir 21, a magnetic ring 25 is installed on the radial side wall of the piston 23. A magnetic induction switch 26 is fixedly connected to the reservoir mounting base 22, with the magnetic induction switch 26 located near the end position of the piston 23 on the reservoir 21. A warning line for the remaining oil level is pre-set at the oil outlet 24 of the reservoir 21, and the magnetic induction switch 26 is specifically installed at the position of the warning line. The magnetic induction switch is a switching device that uses a magnet for sensing. Normally, it is in the open state. When the magnetic ring 25 approaches, the magnetic induction switch closes, and the circuit is connected.
[0037] A magnetic induction switch 26 is electrically connected to a warning light 7. Two magnetic induction switches 26 share one warning light 7, which is used to indicate that the silicone grease in the oil reservoir 21 is low. Specifically, when the piston 23 advances to the end near the oil outlet 24, and the magnetic ring 25 reaches the warning line of the oil outlet 24, the magnetic induction switch 26 senses the magnetic ring 25 and closes, connecting the circuit between the magnetic induction switch 26 and the warning light 7. The warning light 7 illuminates, thus indicating that the silicone grease in the oil reservoir 21 is low, reminding the operator to add silicone grease or replace the oil reservoir 21. Through the oil level alarm device in this embodiment, the remaining silicone grease in the oil reservoir 21 can be automatically monitored, effectively ensuring the stable and reliable operation of the oiling system.
[0038] like Figure 5 As shown, and in combination Figure 1 In another embodiment, the oil outlet device 3 includes a slide rail 31 connected to the top of the frame 6 and two oil outlets 32 connected to the slide rail 31. An oil pipe 5 is connected between the oil outlets 32 and the oil storage cylinder 21. One end of the oil pipe 5 is connected to the oil outlet 24 of the oil storage cylinder 21, and the other end is connected to the oil outlet 32. The silicone grease squeezed out in the oil storage cylinder 21 is transported to the oil outlet 32 through the oil pipe 5.
[0039] See Figures 5-6 The oil outlet 32 is provided with an oiling cavity 33 that can accommodate the end shaft of the air guide plate. The oiling cavity 33 has a single-sided opening structure, specifically a C-shaped cavity, which can cooperate with the end shaft so that the end shaft can fit against the inner wall of the oiling cavity 33. Specifically, the oiling cavity 33 is composed of a hollow bent tube 34 with both ends sealed. A silicone grease inlet pipe 35 is connected to the center of the bent tube 34. The other end of the inlet pipe 35 is an inlet port 36, which is connected to the oil pipe 5. Multiple oil outlet holes 37 are evenly distributed on the side wall of the hollow bent tube 34 facing the opening, so that the oil outlet holes 37 communicate with the oil pipe 5 connected to the oil outlet 32, forming the terminal output structure of the silicone grease in the oiling system. In this embodiment, the inlet pipe 35 is a metal rigid pipe fixedly installed on the oil outlet 32, and the inlet port 36 is a connector with a frustum, which facilitates quick docking with the flexible oil pipe 5.
[0040] After the oil outlet 32 outputs the silicone grease from the oil reservoir 21 through the oil outlet 37, it engages the end shaft of the air guide plate through the opening on the oil outlet 32 and enters the oiling chamber 33. Then, under the engaging action of the two oiling chambers 33, the air guide plate is rotated with the end shaft as the reference axis to complete the uniform coating of silicone grease on the end shaft of the air guide plate.
[0041] Each oil outlet 32 is provided with a guide groove 38 that connects to the slide rail 31, and an adjusting bolt 39 that can fix it on the slide rail 31. Through the cooperation between the slide rail 31 and the guide groove 38, the oil outlet 32 can slide back and forth on the slide rail 31, effectively realizing the adjustable position of the oil outlet 32. The distance between the two oil outlets 32 can be adjusted according to the different lengths of the air guide plate. It is applicable to air guide plates of all lengths that need to be coated with silicone grease, greatly enhancing the versatility of the oiling operation.
[0042] The assembly process of the oiling system in this invention includes:
[0043] First, place the two oil control devices at the bottom of the frame, set the three parameters: inflation pressure, single air release duration, and interval air release time, fill the two oil reservoirs with silicone grease, and fix them to the top of the frame through the oil reservoir fixing base. Connect the oil control devices to the oil reservoirs through the air pipe.
[0044] Secondly, the two oil outlets are fitted onto the slide rail by the cooperation of the guide groove and the slide rail. The oil outlets are fixed onto the slide rail by two adjusting bolts according to the length of the air guide plate. The oil outlets are connected to the oil storage tank by the oil pipe.
[0045] Finally, fix the two magnetic induction switches on the oil drum mounting base, install the warning light on one side of the frame, and connect the two magnetic induction switches and the warning light via electrical wiring.
[0046] When operating after assembly, confirm that the air pressure on the oil control device is turned on and that the oil reservoir is full of silicone grease. Simultaneously turn on the switches of the two oil control devices. After the oil outlet completes the first oil discharge, take the air guide plate and insert the end shaft horizontally into the oil outlet on both sides according to the assembly direction, so that the end shaft fits snugly with the oil outlet cavity. Then, rotate the air guide plate with the end shaft as the rotation base point to complete the uniform coating of silicone grease on the end shaft.
[0047] When setting the adjustment parameters of the oil control device, adjustments can be made according to the actual physical properties of the silicone grease, including viscosity. The following are examples illustrating the application operations of two different types of silicone grease:
[0048] When applying one of the commercially available silicone greases, the inflation pressure of the left oil control device was 0.4 MPaG, the oil outlet interval was 4 seconds, and the oil outlet duration was 3 seconds; the inflation pressure of the right oil control device was 0.6 MPaG, the oil outlet interval was 2 seconds, and the oil outlet duration was 3 seconds.
[0049] When applying another commercially available silicone grease, the inflation pressure of the left oil control device is 0.4 MPaG, the oil outlet interval is 9 seconds, and the oil outlet duration is 0.6 seconds; the inflation pressure of the right oil control device is 0.4 MPaG, the oil outlet interval is 7 seconds, and the oil outlet duration is 0.8 seconds.
[0050] During operation, the air outlet interval can be adjusted according to the actual time of removing the air guide plate to control the oil outlet interval, so that the operation time of removing the air guide plate is shorter than the oil outlet interval, which can meet the production cycle and ensure the continuity of the oiling operation.
[0051] It is important to note that the oiling system in this invention fundamentally improves the oiling conditions for operators, maintains the consistency of silicone grease application, and reliably ensures product quality.
[0052] The present invention also provides an air conditioning production line including the above-mentioned oiling system, which can greatly improve the production efficiency of air conditioners and ensure the uniformity of the production process of all products.
[0053] Finally, it is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the principles and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
