[0011] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0012] Reference Figures 1 to 4 As shown, this utility model provides an automatic oiling device for springs and knobs. In one embodiment, it includes a turntable mechanism 1, a visual inspection mechanism and an oiling mechanism 3 arranged close to the turntable mechanism 1. The oiling mechanism 3 includes an oiling bracket 31, an oiling lifting cylinder 32 installed on one side of the oiling bracket 31, an oiling lifting frame 33 connected to the oiling lifting cylinder 32, and an oiling rotating mechanism 34 installed on the oiling lifting frame 33. The oiling rotating mechanism 34 also drives an oiling connecting horizontal plate 35, and one end of the oiling connecting horizontal plate 35 is also connected to an oiling connecting vertical plate 36. A grease metering valve 37 is also installed on one side of the oiling connecting vertical plate 36, and an oiling needle 38 is also installed at the outlet end of the grease metering valve 37.
[0013] In this embodiment, the turntable mechanism 1 includes a first rotary motor 11, a hollow rotary platform 12 connected to the first rotary motor 11, and a rotary disk 13 mounted on the hollow rotary platform 12; a plurality of fixture seats 14 are installed at intervals along the circumferential direction on the top edge of the rotary disk 13, and a first bearing groove 15 is provided on the top of each fixture seat 14; a limit slot 16 is also provided on part of the inner wall of the first bearing groove 15 along the vertical direction.
[0014] The first rotary motor 11 drives the hollow rotary platform 12 to rotate the rotary disk 13, causing one of the fixture seats 14 to rotate to the assembly position. An external robotic arm first places the rotary switch into the fixture seat 14 (the inner wall of the first bearing groove 15 has a limiting slot 16, and the outer wall of the switch has a protrusion for positioning and limiting the switch). Then, the spring is assembled onto the rotary switch to complete the assembly (the switch has a connecting post, and the spring has a hole corresponding to the connecting post; the spring is secured in the connecting post through the hole so that the two can be riveted together by hot rivets). Subsequently, the rotary disk rotates the assembled product to the hot riveting position. After hot riveting, it is rotated to the vision inspection mechanism, which inspects the deformation of the spring and the height of the rivet points. After passing the inspection, the rotary disk 13 rotates to... When the product is transferred to the oiling mechanism 3, the oiling lifting cylinder 32 is activated, pushing the oiling lifting frame 33 downward, causing the oiling needle 38 to descend to the predetermined oiling position. The grease metering valve 37 (the use of the grease metering valve 37 ensures the accuracy of each oiling amount, avoiding problems such as uneven, excessive, or insufficient oiling that may occur during manual oiling) is connected to the external oil tank. Oil is injected into the predetermined position of the product through the oiling needle 38. At the same time, the oiling rotation mechanism 34 can drive the grease metering valve 37 to rotate the oiling needle 38 to inject grease into different areas. After the oiling is completed, the rotating disk 13 rotates again to the unloading position, and the external robot transfers and unloads the product. Products that fail the visual inspection are not oiled and are directly transferred to the product recycling area by the robot.
[0015] Preferably, in this embodiment, the oil injection rotation mechanism 34 includes a bearing seat mounted on the oil injection lifting frame 33, a mounting bearing mounted on the bearing seat, an oil injection rotating shaft 341 arranged vertically and connected to the mounting bearing, an oil injection rotating motor 342 mounted on the oil injection lifting frame 33, a drive wheel 343 connected to the oil injection rotating motor 342, a driven wheel 344 mounted on the upper part of the oil injection rotating shaft 341, and a synchronous belt 345 wound between the drive wheel 343 and the driven wheel 344; the top of the oil injection connecting horizontal plate 35 is connected to the bottom of the oil injection rotating shaft 341. The oil injection rotation mechanism 34 adopts a transmission method of motor combined with synchronous belt 345 and synchronous pulley, which can ensure the stability of the rotation of oil injection needle 38.
[0016] In one embodiment, the visual inspection mechanism includes a deformation detection module 2 and a height detection module 4. The deformation detection module 2 includes a supporting vertical plate 21, a supporting horizontal plate 22 connected to the top of the supporting vertical plate 21, and a detection translation cylinder 23 installed at the bottom of the supporting horizontal plate 22 along its length. The detection translation cylinder 23 also drives a detection connecting plate 24, and the bottom of the detection connecting plate 24 is also connected to a first connecting vertical plate. A first connecting horizontal plate is also connected to one side of the first connecting vertical plate, and a ring light source 25 is also installed on the first connecting horizontal plate. A fixed column 26 is also installed on the top of the supporting horizontal plate 22, and a camera mounting base 27 is also installed on the upper part of the fixed column 26. A detection camera 28 is also installed at one end of the camera mounting base 27, and the detection camera 28 is located above the ring light source 25.
[0017] When the product to be inspected reaches below the visual inspection mechanism, the inspection translation cylinder 23 is activated, pushing the inspection connecting plate 24 to move along the length of the support horizontal plate 22. The inspection connecting plate 24 drives the first connecting vertical plate and the first connecting horizontal plate to move, thereby moving the ring light source 25 below the inspection camera 28. The ring light source 25 provides uniform illumination, ensuring that the inspection camera 28 can clearly capture the image of the spring to determine whether the spring has quality problems such as deformation.
[0018] In one embodiment, the height detection module 4 includes an X-axis translation module 41 arranged at one end of the vertical support plate 22 along its length, a Y-axis translation module 42 connected to the X-axis translation module 41, and a height detection plate 43 connected to the Y-axis translation module 42; a laser displacement sensor 44 is also installed at the end of the height detection plate 43 near the ring light source 25. The X-axis translation module 41 and the Y-axis translation module 42 can be linear modules. In this embodiment, the rivet height is detected using an XY module combined with the laser displacement sensor 44. Compared with commonly used 3D line scanning height detection solutions, this method is lower in cost and more suitable for small and medium-sized enterprises.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
