Description

Technical Field

[0001] This application relates to the field of riveting technology, and more specifically, to an oiling detection device for riveting equipment. Background Technology

[0002] Rivets need to be oiled before they are pressed together. In the prior art, an oil-immersed sleeve is set on the socket. When the rivet is inserted into the socket, it can contact the oil-immersed sleeve to apply oil. At the same time, a vision inspection machine performs visual inspection on the rivet.

[0003] When the robotic arm picks up a rivet and inserts it into the socket, it will release it in advance to prevent the robotic arm from hitting the socket and allowing the rivet to fall freely. However, in order to ensure that the rivet is evenly coated with oil around its circumference, the oil-soaked sleeve is tightly fitted to the rivet, which makes it difficult for the rivet to fall to the bottom quickly or even get stuck, affecting the inspection results of the vision inspection machine. Utility Model Content

[0004] To overcome the above deficiencies, this application provides an oiling detection device for riveting equipment, which aims to improve the problems mentioned in the background art.

[0005] This application provides an oiling detection device for riveting equipment, including a base plate, a socket and a vision detection mechanism on the base plate, an oil-immersed sleeve inside the socket, a rivet movably inserted into the socket, the lower end of the rivet being inserted into the oil-immersed sleeve, an electromagnetic mechanism inside the socket being magnetically connected to the rivet, the vision detection mechanism facing the rivet, and an oil supply mechanism connected to the socket.

[0006] In one specific implementation, the visual inspection mechanism includes a column, which is fixedly connected to the base plate, and a crossbar is installed on the column, with a camera mounted on the crossbar.

[0007] In the above implementation process, both the crossbar and the column are spliced ​​with aluminum profiles, which makes it easy to adjust the position of the camera. After adjustment, the position of the camera is fixed.

[0008] In one specific implementation, the visual inspection mechanism further includes a backlight panel mounted at the distal end of the crossbar, the backlight panel being located behind the rivet.

[0009] In the above implementation process, when the camera takes a picture, the backlight is powered on and emits light, serving as the background of the rivet and clearly showing its outline, so that the visual inspection agency can accurately detect it.

[0010] In one specific implementation, the socket includes a stand, a detachable end cap on the stand, an oil groove on the stand, an oil-immersed sleeve located in the oil groove, an insertion hole on the end cap that matches the rivet, and a gasket between the end cap and the oil-immersed sleeve.

[0011] In the above implementation process, the end cap is fixed to the upright with four screws. The oil-immersing sleeve can be inserted by opening the end cap. A gasket of appropriate thickness is placed on the end face of the oil-immersing sleeve. After the end cap is closed and tightened, the oil-immersing sleeve is pushed down to the appropriate position. The oil-immersing sleeve expands and tightens on the inner wall of the upright due to its own elasticity, thereby adjusting the oil-immersing height of the rivet. In addition, this expansion force is much greater than the friction between the oil-immersing sleeve and the rivet, so as to avoid the oil-immersing sleeve from loosening after the rivet is frequently dipped in oil. In this embodiment, the oil-immersing sleeve is felt.

[0012] In one specific implementation, the upright is provided with an oil inlet and an oil overflow outlet. The oil inlet is located at the bottom of the oil tank, and the oil overflow outlet is located at the top of the oil tank. An oil storage bottle is connected to the oil overflow outlet.

[0013] In the above process, the oil supply mechanism injects oil into the oil tank through the oil inlet. If too much oil is injected, it overflows from the overflow port and flows into the oil storage bottle, ensuring that the amount of oil in the oil tank is appropriate.

[0014] In one specific implementation, the electromagnetic mechanism includes an electromagnet and a stop rod, the stop rod pressing the electromagnet against the inside of the column, and a sealing ring fitted on the iron core of the electromagnet abutting against the inner wall of the column.

[0015] In the above process, before the column and base plate are installed and fixed, the electromagnet is inserted into the column, and then the abutment is inserted. This allows the electromagnet to be held at the upper end of the column. The abutment can be made of plastic, and the sealing ring can prevent the oil in the oil tank from overflowing through the gaps in the iron core.

[0016] In one specific implementation, the oil supply mechanism includes a clamp holding an oil can, the oil can being suspended and connected to the oil inlet.

[0017] In the above process, the clamp is installed at a high position on the riveting equipment and is suspended. The oil will automatically flow into the oil tank under the action of gravity, eliminating the need for an oil pump and reducing costs.

[0018] In one specific implementation, the oil supply mechanism further includes a metering valve, which is mounted on the column and connected in series between the oil inlet and the oil reservoir.

[0019] In the above process, the metering valve is used to set the oil supply once after N dips to ensure that the amount of oil in the oil tank is appropriate.

[0020] Compared with the prior art, the beneficial effects of this application are: by setting an oil-immersed sleeve inside the socket, when the rivet is inserted into the socket, the electromagnet is energized to attract the rivet downwards, ensuring that the rivet falls to the bottom, thereby ensuring the accuracy of the oil-immersing height and the measurement by the visual inspection mechanism.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0025] Please see Figures 1-4 This application provides an oiling detection device for riveting equipment, including a base plate 10. A socket 20 and a vision inspection mechanism 30 are mounted on the base plate 10. An oil-immersing sleeve 40 is disposed inside the socket 20. A rivet 50 is movably inserted into the socket 20, with its lower end inserted into the oil-immersing sleeve 40. An electromagnetic mechanism 60 is disposed inside the socket 20 and magnetically connected to the rivet 50. The vision inspection mechanism 30 faces the rivet 50. An oil supply mechanism 70 is connected to the socket 20. Specifically, by using the oil-immersing sleeve 40 inside the socket 20, when the rivet 50 is inserted into the socket 20, the electromagnet 61 is energized to attract the rivet 50 downwards, ensuring that the rivet 50 reaches the bottom, thus ensuring the accuracy of the oiling height and the measurement by the vision inspection mechanism 30.

[0026] Please see Figures 1-4The visual inspection mechanism 30 includes a column 31, which is fixedly connected to the base plate 10. A crossbar 32 is installed on the column 31, and a camera 33 is installed on the crossbar 32. Both the crossbar 32 and the column 31 are made of aluminum profile splicing, which facilitates the adjustment of the position of the camera 33. After adjustment, the position of the camera 33 is fixed.

[0027] Please see Figures 1-4 The visual inspection mechanism 30 also includes a backlight panel 34, which is mounted at the far end of the crossbar 32 and located behind the rivet 50. When the camera 33 takes a picture, the backlight panel 34 is powered on and emits light, serving as a background for the rivet 50 and clearly showing its outline, so that the visual inspection mechanism 30 can accurately inspect it.

[0028] Please see Figures 1-4 The socket 20 includes a pole 21 with a detachable end cap 22. An oil groove is formed on the pole 21, and an oil-soaked sleeve 40 is located within the oil groove. An insertion hole is formed on the end cap 22 to accommodate a rivet 50. A gasket 23 is placed between the end cap 22 and the oil-soaked sleeve 40. The end cap 22 is fixed to the pole 21 by four screws. Opening the end cap 22 allows the oil-soaked sleeve 40 to be inserted. A gasket 23 of appropriate thickness is placed on the end face of the oil-soaked sleeve 40. After closing and tightening the end cap 22, the oil-soaked sleeve 40 is pushed downwards to a suitable position. Due to its elasticity, the oil-soaked sleeve 40 expands tightly against the inner wall of the pole 21, thereby adjusting the oil-soaking height of the rivet 50. Furthermore, this expansion force is much greater than the frictional force between the oil-soaked sleeve 40 and the rivet 50 to prevent the oil-soaked sleeve 40 from loosening after frequent oiling of the rivet 50. In this embodiment, the oil-soaked sleeve 40 is made of felt.

[0029] Please see Figures 1-4 The upright 21 has an oil inlet 24 and an oil overflow outlet 25. The oil inlet 24 is located at the bottom of the oil tank, and the oil overflow outlet 25 is located at the top of the oil tank. An oil storage bottle 26 is connected to the oil overflow outlet 25. The oil supply mechanism 70 injects oil into the oil tank through the oil inlet 24. If too much oil is injected, it overflows from the oil overflow outlet 25 and flows into the oil storage bottle 26, ensuring that the oil level in the oil tank is appropriate.

[0030] Please see Figures 1-4 The electromagnetic mechanism 60 includes an electromagnet 61 and a stop rod 62. The stop rod 62 presses the electromagnet 61 tightly against the column 31. A sealing ring 63 is fitted onto the iron core of the electromagnet 61, which abuts against the inner wall of the column 21. Before the column 31 is installed and fixed to the base plate 10, the electromagnet 61 is inserted into the column 21, and then the stop rod 62 is inserted. This allows the electromagnet 61 to be held in the upper position of the column 21. The stop rod 62 can be made of plastic, and the sealing ring 63 prevents oil in the oil tank from leaking out through the gaps in the iron core.

[0031] Please see Figures 1-4The oil supply mechanism 70 includes a clamp 71, on which an oil reservoir 72 is held. The oil reservoir 72 is suspended and connected to the oil inlet 24. The clamp 71 is installed at a high position on the riveting equipment and is suspended. The oil will automatically flow into the oil tank under gravity, eliminating the need for an oil pump and reducing costs.

[0032] Please see Figures 1-4 The oil supply mechanism 70 also includes a metering valve 73, which is mounted on the column 31 and connected in series between the oil inlet 24 and the oil reservoir 72. The metering valve 73 is used to set the oil supply to be once after N dipping cycles, ensuring that the oil level in the oil tank is appropriate.

[0033] The working principle of the oiling detection device for this riveting equipment is as follows: Open the end cover 22, insert the oil-immersed sleeve 40 into the oil groove at the upper end of the upright 21, place a shim 23 of appropriate thickness on the end face of the oil-immersed sleeve 40, close the end cover 22 and tighten it. The oil-immersed sleeve 40 is then pushed downwards to the appropriate position. Due to its own elasticity, the oil-immersed sleeve 40 expands tightly against the inner wall of the upright 21, thereby adjusting the oiling height of the rivet 50. During operation, the robotic arm grabs the rivet 50 and places it into the insertion hole on the end frame. Electromagnet 61... When energized, the rivet 50 is attracted downwards, ensuring that it reaches the bottom. The lower end of the rivet 50 contacts the oil-immersing sleeve 40 to achieve oiling at the specified height. At the same time, the vision inspection mechanism 30 takes a picture of the upper end of the rivet 50 to confirm its size. In summary, an oil-immersing sleeve 40 is installed inside the socket 20. When the rivet 50 is inserted into the socket 20, the electromagnet 61 is energized to attract the rivet 50 downwards, ensuring that it reaches the bottom, thus ensuring the accuracy of the oiling height and the measurement by the vision inspection mechanism 30.
