Description

Technical Field

[0001] The present invention relates to the technical field of gas meter manufacturing, and particularly relates to an oil film coating device for the vertical shaft assembly section of a gas meter manufactured based on the industrial Internet of Things. Background Art

[0002] During the manufacturing of a gas meter, it is necessary to install a vertical shaft as shown in Figure 1 . The existing method usually adopts manual assembly. However, manual assembly not only has low efficiency, but also easily causes damage to the outer surface of the column when clamping the vertical shaft, and it is also easy to install the vertical shaft in the wrong direction during the assembly process. At the same time, during the assembly of the vertical shaft, silicone oil needs to be applied to specific parts of the surface of the vertical shaft to play a lubricating and sealing role. However, when using manual assembly, it is also difficult to control the amount of silicone oil applied. Applying too much causes waste of silicone oil and pollution to other parts of the product, while applying too little fails to achieve the lubricating effect. Summary of the Invention

[0047] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0048] Embodiment

[0049] As Figures 2 to 16 shown, the present invention includes a loading and positioning mechanism 1, a loading and unloading clamping mechanism, and a silicone oil coating mechanism 2. The loading and positioning mechanism 1 includes a loading unit and a positioning unit. The loading unit is used to transfer the vertical shaft 10 to the positioning unit, and the positioning unit is used to position the vertical shaft 10 transferred by the loading unit. The loading and unloading clamping mechanism is used to grab the vertical shaft 10 located at the positioning unit and transfer the vertical shaft 10 to the silicone oil coating mechanism 2. The silicone oil coating mechanism 2 is used to automatically coat the silicone oil on the circumferential outer wall of the vertical shaft 10.

[0050] During the assembly process of the vertical shaft 10 of the gas meter in the prior art, most of them are manually assembled. The manual assembly method not only has low efficiency, but also because the vertical shaft 10 Figure 1 As shown, the diameters of both ends of the vertical shaft 10 are different, and the diameter of its head is smaller. This causes the situation that the vertical shaft 10 is easily assembled in the reverse direction during manual assembly. Moreover, during the assembly process of the vertical shaft 10, it is necessary to coat the silicone oil on the circumferential outer wall of the vertical shaft 10 to play a lubricating and sealing role. However, it is not convenient for workers to manually coat the silicone oil to control the amount of silicone oil coated. Too much silicone oil coated will cause waste of silicone oil and pollution to other parts of the product, and too little coating will not achieve the lubricating effect. For this reason, the present technical solution respectively sets a loading and positioning mechanism 1, a loading and unloading clamping mechanism, and a silicone oil coating mechanism 2 in the assembly workshop site of the vertical shaft. Among them, the set loading and positioning mechanism 1 automatically loads the vertical shaft 10 by the loading unit, transports the vertical shafts 10 to be assembled to the positioning unit one by one, and uses the set positioning unit to position the vertical shaft 10 so that the loading and unloading clamping mechanism can accurately clamp the vertical shaft 10. At the same time, the set positioning unit can prevent the loading and unloading clamping mechanism from assembling the vertical shaft 10 in the reverse direction. After the set loading and positioning mechanism 1 transports the vertical shaft 10 to the positioning unit, the set loading and unloading clamping mechanism clamps the vertical shaft 10 at the positioning unit, and then transfers the clamped vertical shaft 10 to the silicone oil coating mechanism 2. The silicone oil coating mechanism 2 automatically coats the silicone oil on the circumferential outer wall of the vertical shaft 10. Finally, the coated vertical shaft 10 is transferred to the assembly line by the loading and unloading clamping mechanism, and the vertical shaft 10 is automatically assembled into the gas meter housing, thus achieving the purpose of automatically assembling the vertical shaft 10.

[0051] The feeding unit includes a support frame 5, a vibrating bowl 6, a linear vibrator 12 and a transfer plate 13; the vibrating bowl 6 is fixed on the support frame 5, the linear vibrator 12 is fixed on the vibrating bowl 6 through a support plate 11, one end of the transfer plate 13 is connected to the output end of the vibrating bowl 6, and the linear vibrator 12 is located at the bottom of the transfer plate 13.

[0052] The provided support frame 5 is used to support the vibrating bowl 6, ensuring that the vibrating bowl 6 can be stably placed in the assembly workshop of the vertical shaft; the provided vibrating bowl 6 is used to automatically convey the vertical shaft 10 to be installed, and the vertical shafts are successively transferred to the transfer plate 13 by vibration, and then the transfer plate 13 is vibrated by the provided linear vibrator 12, so that the vertical shafts 10 on the transfer plate 13 continue to be conveyed towards the positioning unit by vibration, thus realizing the automatic feeding of the vertical shafts 10; in this technical solution, the vertical shafts 10 are pre-uniformly placed in the vibrating bowl 6 in one direction, so that when the vibrating bowl 6 conveys the vertical shafts 10 by vibration, it can prevent the vertical shafts 10 from being conveyed into the transfer plate 13 backwards, effectively preventing the situation of the vertical shafts 10 being installed in reverse.

[0053] The positioning unit includes a positioning plate 15, a first driving mechanism 20 and a slider 16; the positioning plate 15 is connected to the other end of the transfer plate 13, strip-shaped grooves 14 that communicate with each other are provided on both the positioning plate 15 and the transfer plate 13, and the width of the strip-shaped grooves 14 is the same as the maximum outer diameter of the vertical shaft 10; an installation frame 19 is provided at the bottom of the positioning plate 15, the first driving mechanism 20 is fixed on the installation frame 19, a notch 22 is provided on the positioning plate 15, and the notch 22 disconnects the strip-shaped grooves 14 on the positioning plate 15; the slider 16 is connected to the output end of the first driving mechanism 20, and the first driving mechanism 20 is used to drive the slider 16 to penetrate into the notch 22, and a strip-shaped opening 23 that can communicate with the strip-shaped grooves 14 is also provided on the slider 16, and the width of the strip-shaped opening 23 is the same as the maximum outer diameter of the vertical shaft 10.

[0054] In this technical solution, strip-shaped grooves 14 for conveying the vertical shafts 10 are provided on both the transfer plate 13 and the positioning plate 15. In order to ensure that the vertical shafts 10 can move stably in the strip-shaped grooves 14, the width of the strip-shaped grooves 14 is the same as the maximum outer diameter of the vertical shaft 10, so that the vertical shafts 10 in the strip-shaped grooves 14 of the transfer plate 13 are stably conveyed into the strip-shaped grooves 14 of the positioning plate 15 under the action of the linear vibrator 12. In order to ensure that the vertical shafts 10 located in the strip-shaped grooves 14 are not easily vibrated out of the strip-shaped grooves 14 during the vibration of the transfer plate 13 by the linear vibrator 12, a cover plate 21 is also provided on the transfer plate 13, preventing the vertical shafts 10 in the transfer plate 13 from being shaken out of the strip-shaped grooves 14 under the action of the linear vibrator 12.

[0055] At the same time, since the depth of the provided strip groove 14 is greater than the diameter of the vertical shaft 10, the vertical shaft 10 is recessed in the positioning plate 15. However, in order to ensure that the loading and unloading clamping mechanism can smoothly clamp the vertical shaft 10 located on the positioning plate 15, a notch 22 is provided on the positioning plate 15. The notch 22 cuts off the strip groove 14 on the positioning plate 15, and a slider 16 is also provided in the notch 22. A strip opening 23 with the same width and depth as the strip groove 14 is provided on the slider 16. When the vertical shaft 10 in the strip groove 14 of the transfer plate 13 is transferred to the strip groove 14 in the positioning plate 15, the first driving mechanism 20 drives the slider 16 to move upward, so that the strip opening 23 on the slider 16 moves to communicate with the strip groove 14 on the positioning plate 15, forming an integral structure with the provided positioning plate 15. In this way, the vertical shaft 10 entering the positioning plate 15 slides downward along the strip groove 14. Under the action of the slider 16, it is ensured that the vertical shaft 10 can smoothly slide in the positioning plate 15 and prevent the vertical shaft 10 from deviating in direction; when the vertical shaft 10 is in place, the first driving mechanism 20 is used to drive the slider 16 to move downward, leaving a space for the loading and unloading clamping mechanism to clamp the vertical shaft 10. That is, under the action of the notch 22 on the positioning plate 15, the loading and unloading clamping mechanism can accurately and quickly clamp the vertical shaft 10 on the positioning plate 15 through the notch 22, so as to transfer the vertical shaft 10 to the silicone oil coating mechanism 2 for silicone oil coating.

[0056] The positioning unit further includes a positioning block 18. The positioning block 18 is located at the end of the positioning plate 15 away from the transfer plate 13. The positioning block 18 is provided with a first positioning groove 26 and a second positioning groove 25 that communicate with each other. The width of the first positioning groove 26 is the same as the maximum outer diameter of the vertical shaft 10, and the width of the second positioning groove 25 is the same as the outer diameter of the head of the vertical shaft 10; two detection units 17 are also provided on the side wall of the positioning block 18, and the two detection units 17 respectively extend into the first positioning groove 26 and the second positioning groove 25.

[0057] In order to facilitate the subsequent application of silicone oil to the vertical shaft 10 and the installation of the vertical shaft 10, a loading and unloading clamping mechanism is required to clamp the middle part of the vertical shaft 10. In order to ensure that the middle part of the vertical shaft 10 stays at the notch 22 of the positioning plate 15, a positioning block 18 is further provided at the end of the positioning plate 15. The positioning block 18 is provided with a first positioning groove 26 and a second positioning groove 25. When the vertical shaft 10 slides on the positioning plate 15 in the normal installation direction, since the diameter of the head end of the vertical shaft 10 is smaller, the head of the vertical shaft 10 finally slides into the second positioning groove 25 after passing through the first positioning groove 26. The width of the second positioning groove 25 is smaller than the outer diameter of the middle section of the vertical shaft 10. Therefore, the vertical shaft 10 cannot continue to slide on the positioning plate 15 under the action of the second positioning groove 25, and finally realizes the precise positioning of the vertical shaft 10 on the positioning plate 15, ensuring that the central position of the vertical shaft 10 is at the notch 22, and further ensuring that the loading and unloading clamping unit clamps the central position of the vertical shaft 10.

[0058] The provided detection unit 17 is an infrared sensor, which is used to detect whether there is a vertical shaft 10 in the first positioning groove 26 and the second positioning groove 25. The vertical shaft 10 in the vibrating disk 6 is automatically transported into the transfer plate 13. When the vertical shaft 10 is placed reversely, that is, the tail of the vertical shaft 10 slides along the strip groove 14. In this way, when the tail of the vertical shaft 10 slides to the end of the first positioning groove 26 of the positioning block 18, it cannot continue to slide into the second positioning groove 25. This causes the detection unit 17 located in the second positioning groove 25 to not detect the presence of the vertical shaft 10. When the detection unit 17 located in the first positioning groove 26 detects the presence of the vertical shaft 10, it can be determined at this time that the vertical shaft 10 transported from the vibrating disk 6 to the positioning plate 15 is in a reverse state, avoiding the loading and unloading clamping unit from clamping the vertically-reversed shaft 10.

[0059] The loading and unloading clamping mechanism includes a manipulator 3 and a clamping unit 4, and the clamping unit 4 is connected to the movable end of the manipulator 3;

[0060] The clamping unit 4 includes a connecting plate 38, two second driving mechanisms 41 and two loading grippers 39. The connecting plate 38 is connected to the movable end of the manipulator 3. The second driving mechanism 41 is fixed on the connecting plate 38. The two loading grippers 39 are connected to the output ends of the second driving mechanisms 41. The second driving mechanism 41 is used to drive the two loading grippers 39 to approach or separate; a limiting block 40 is further provided on the second driving mechanism 41, and the limiting block 40 is located between the clamping surfaces on both sides of the loading gripper 39; both the strip groove 14 and the strip opening 23 are two, and the distance between the two strip openings 23 is the same as the width of the limiting block 40.

[0061] In order to improve the assembly efficiency of the vertical shaft 10, two strip-shaped grooves 14 are provided on both the transfer plate 13 and the positioning plate 15. In order to apply silicone oil to multiple vertical shafts 10 simultaneously, two second driving mechanisms 41 are provided on the connecting plate 38 in this technical solution. Feeding jaws 39 are provided at the output ends of the two second driving mechanisms 41, and a limiting block 40 is provided between the feeding jaws 29. In this way, when the clamping unit 4 is working, the manipulator 3 is first used to adjust the position of the feeding jaw 39 on one of the second driving mechanisms 41 so that the feeding jaw 39 can clamp the two vertical shafts 10 located at the notch 22 of the positioning plate 15. Then, when the subsequent vertical shafts 10 continue to move onto the positioning plate 15, the manipulator 3 is used to re-adjust the position of the clamping unit 4 so that the feeding jaw 39 on the other second driving mechanism 41 is located at the notch 22 of the positioning plate 15 and clamps the vertical shafts 10 at the notch 22. The clamping unit 4 arranged in this way can transfer four vertical shafts 10 to be coated with silicone oil to the silicone oil coating mechanism 2 at one time, thus improving the assembly efficiency of the vertical shaft 10.

[0062] At the same time, in order to ensure that the feeding jaws 39 provided can accurately clamp the two vertical shafts 10 in the notch 22 of the positioning plate 15, a limiting block 40 is also provided between the feeding jaws 39. The limiting block 40 has a rectangular structure, a weight-reducing opening is provided at its central position, and the width of the limiting block 40 is the same as the distance between the two strip-shaped openings 23 on the slider 16. In this way, when the manipulator 3 drives the clamping unit 4 to move onto the positioning plate 15, the provided limiting block 40 is exactly between the two strip-shaped openings 23 of the slider 16, and the two sides of the limiting block 40 are exactly in contact with the outer walls of the two vertical shafts 10 located in the notch 22. In this way, when the second driving mechanism 41 drives the feeding jaw 39 to move towards the limiting block 40, the feeding jaw 39 can fix the two vertical shafts 10 on both sides of the limiting block 40 at the same time, thus achieving the purpose of accurately grasping the two vertical shafts 10 at one time and improving the assembly efficiency of the vertical shaft 10.

[0063] The silicone oil coating mechanism 2 includes an oil feeder 28, a third driving mechanism 29, a clamping mechanism 30 and a support column 42. The third driving mechanism 29 is fixed on the support column 42. The clamping mechanism 30 is connected to the output end of the third driving mechanism 29. An oil coating unit 32 connected to the oil feeder 28 through a pipeline is provided on the clamping surface of the clamping mechanism 30. The third driving mechanism 29 is used to drive the clamping mechanism 30 to fit the oil coating unit 32 on the circumferential outer wall of the vertical shaft 10. The oil coating unit 32 is used to apply silicone oil on the circumferential outer wall of the vertical shaft 10.

[0064] The inside of the provided oil feeder 28 is filled with silicone oil. The oil pump on the oil feeder 28 can transport the silicone oil to the oiling unit 32 through a pipeline. The oiling unit 32 in this technical solution is a sponge, which has a certain adsorption capacity for silicone oil. After the clamping unit 4 grabs the vertical shaft 10 on the positioning plate 15, the manipulator 3 is used to transfer the clamping unit 4 to the silicone oil oiling structure 2, and the vertical shaft 10 clamped by the clamping unit 4 is placed between the clamping mechanisms 30. At this time, the third driving mechanism 29 drives the clamping mechanisms 30 to clamp the vertical shaft 10. Since the coating unit 32 is provided on the clamping surface of the clamping mechanism 30 and the coating unit 32 adsorbs the silicone oil transported by the oil feeder 28, during the process of the clamping unit 30 clamping the vertical shaft 10, the silicone oil adsorbed on the oiling unit 32 will adhere to the circumferential outer wall of the vertical shaft 10, thus achieving the purpose of automatically coating the vertical shaft 10 with silicone oil.

[0065] Two movable blocks 34 are provided on the output end of the third driving mechanism 29, and the third driving mechanism 29 is used to drive the two movable blocks 34 to approach or separate; a first cross plate 33 is provided on one of the movable blocks 34, and a second cross plate 35 parallel to the first cross plate 33 is provided on the other movable block 34; the clamping mechanism 30 includes a plurality of clamping blocks 31, and connecting columns 37 are provided on the clamping blocks 31, and the connecting columns 37 on adjacent two clamping blocks 31 are respectively connected to the first cross plate 33 and the second cross plate 35.

[0066] Since four vertical shafts 10 are simultaneously grabbed by the clamping unit 4 in this technical solution, in order to ensure that the provided silicone oil coating mechanism can simultaneously coat silicone oil on multiple vertical shafts 10, two movable blocks 34 are provided on the output end of the third driving mechanism 29 in this technical solution. The two movable blocks 34 are respectively connected to two mutually parallel first cross plate 33 and second cross plate 35. At the same time, connecting columns 37 are provided on all the clamping blocks 31 provided, and the connecting columns 37 on adjacent two clamping blocks 31 are respectively connected to the first cross plate 33 and the second cross plate 35. In this way, when the third driving mechanism 29 works, it drives the first cross plate 33 and the second cross plate 35 to move towards each other, which ensures that two clamping blocks 31 in the same group can approach each other, thus ensuring that multiple clamping blocks 31 can simultaneously clamp multiple vertical shafts 10. During the clamping process of the clamping blocks 31, the oiling unit 32 located on the clamping surface of the clamping blocks 31 is squeezed by the vertical shafts 10, so that the silicone oil adsorbed by the oiling unit 32 is automatically coated on the vertical shafts 10, and finally the purpose of synchronously and automatically coating silicone oil on multiple vertical shafts 10 is achieved.

[0067] When the silicone oil coating mechanism 2 is used to coat the vertical shaft 10 on the clamping unit 4 with silicone oil, the manipulator 3 is used to transfer the vertical shaft 10 on the clamping unit 4 between the two clamping blocks 31. The third driving mechanism 29 drives the clamping blocks 31 on both sides of the vertical shaft 10 to move towards the two circumferential sides of the vertical shaft 10. Finally, the oil coating unit 32 on the clamping blocks 31 contacts the outer walls on the two circumferential sides of the vertical shaft 10. As the oil coating unit 32 continuously contacts the outer wall of the vertical shaft 10, the silicone oil adsorbed in the oil coating unit 32 is finally extruded onto the outer wall of the vertical shaft 10, achieving the purpose of automatically coating the outer wall of the vertical shaft 10 with silicone oil. By controlling the distance that the third driving mechanism 29 drives the clamping block 31 to move towards the vertical shaft 10, the squeezing force between the oil coating unit 32 and the vertical shaft 10 can be achieved, thereby controlling the amount of silicone oil extruded from the oil coating unit 32 and avoiding the situation of too much or too little silicone oil being coated on the outer wall of the vertical shaft 10.

[0068] When applying silicone oil to the outer wall of the opposing shaft 10 using the application unit 32, the manipulator 3 is used to drive the movement of the clamping unit 4, enabling relative displacement between the vertical shaft 10 and the application unit 32. In this way, during the process of applying silicone oil to the vertical shaft 10, the vertical shaft 10 is moved within the application unit 32. As the vertical shaft 10 moves, the silicone oil can be sequentially applied along the axial direction of the vertical shaft 10 to the outer wall of the vertical shaft 10, thereby achieving the axial application of silicone oil to the outer wall of the vertical shaft 10 and expanding the axial silicone oil application area on the vertical shaft 10. At the same time, due to the extrusion between the outer wall of the vertical shaft 10 and the application unit 32 in this technical solution, the silicone oil adsorbed by the application unit 32 is transferred to the outer wall of the vertical shaft 10. The clamping surface of the clamping block 31 is a straight surface, and the vertical shaft 10 has a cylindrical structure. Therefore, when the application unit 32 on the clamping block 31 comes into extrusion contact with the vertical shaft 10, the silicone oil on the application unit 32 is applied to the contact outer wall between the vertical shaft 10 and the application unit 32, that is, the silicone oil is applied to the circumferential two sides of the vertical shaft 10. The outer walls in the upper and lower surface directions of the vertical shaft 10 are not in contact with the application unit 32, resulting in no silicone oil being applied to this area. However, when the vertical shaft 10 is assembled into the gas meter housing, the vertical shaft 10 and the gas meter housing will rotate relative to each other. Therefore, when the vertical shaft 10 rotates around its own axis, the silicone oil originally applied to the circumference of the vertical shaft 10 will gradually and automatically evenly apply the silicone oil to the circumferential outer wall of the vertical shaft 10 as the vertical shaft 10 rotates. Assuming that when the application unit 32 applies silicone oil to the vertical shaft 10, the circumference of the vertical shaft 10 is evenly coated with silicone oil, this will cause when the vertical shaft 10 is assembled into the shaft hole in the gas meter housing, due to silicone oil adhering to the entire circumference of the vertical shaft 10, a part of the silicone oil on the outer wall of the vertical shaft 10 will be squeezed out from the vertical shaft 10, contaminating other parts of the gas meter housing. In this technical solution, during the extrusion process of the application unit 32, the extruded silicone oil can only adhere to the circumferential two sides of the vertical shaft 10. In this way, when the vertical shaft 10 is assembled into the shaft hole of the gas meter housing, since there is still a part of the circumference of the vertical shaft 10 that is not coated with silicone oil, the silicone oil on the vertical shaft 10 that is squeezed during the installation process can automatically fill the uncoated part of the outer wall of the vertical shaft 10. And during the assembly process of the vertical shaft 10, as the vertical shaft 10 rotates around its own axis, it can further evenly apply the silicone oil on the outer wall of the vertical shaft 10 to the circumference, avoiding the situation where excessive silicone oil overflows from the assembly hole and contaminates other components.

[0069] An oil receiving tray 27 is also provided on the side wall of the support column 42. The oil receiving tray 27 is located directly below the application unit 32. The oil receiving tray 27 provided can centrally collect the silicone oil extruded and dripped by the application unit 32.
