Description

Technical Field

[0001] This invention relates to the field of automated oiling technology, and more specifically, to an automated oiling system and its operating method. Background Technology

[0002] Traditional oiling systems lack adaptable clamping structures, making it difficult to accommodate the clamping needs of plate-shaped workpieces of different shapes. Existing clamping structures have poor adaptability and cannot achieve a close fit when faced with plate-shaped workpieces of complex shapes such as circles and rectangles through structural adjustments. At the same time, their fixed clamping methods cannot distinguish the characteristics of thin and thick plates. For thin plates, excessive clamping force can easily cause deformation or wobbling due to loose clamping. For thick plates, insufficient contact points can easily lead to unstable support. Ultimately, all of these factors will affect the positioning accuracy of the workpiece during the oiling process, resulting in problems such as uneven oiling and missed coating.

[0003] Traditional flipping structures mostly adopt a uniform flipping mode, which cannot adjust the flipping method according to the physical characteristics of thin and thick plates: For thick plates, due to their large weight, stable right-angle flipping is required to avoid workpiece displacement during the flipping process, but existing structures cannot provide sufficient support stability; For thin plates, gentle flipping is required to prevent wrinkles or deformation, but existing structures are prone to workpiece damage due to improper control of flipping force.

[0004] Traditional oiling systems often lack coordination between the clamping structure and the flipping mechanism, and have a weak overall ability to adapt to diverse workpieces. The clamping action of the clamping structure and the flipping action of the flipping mechanism often have a disconnect, making it impossible to adjust the state synchronously according to the shape and thickness of the workpiece to match the working rhythm of the oiling robot arm. At the same time, the system as a whole does not have linkage logic designed for the "automated flow oiling of workpieces of different specifications and shapes". When dealing with diverse plate-shaped workpieces, frequent manual changes of fixtures or adjustments of parameters are required, making it difficult to achieve full-process automation and meet the needs of efficient and stable batch oiling production. In view of this, we propose an automatic oiling system and its working method. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic oiling system and its working method to solve the technical problem that unstable clamping of workpieces with thickness differences affects the oiling effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic oiling system, comprising a cabinet, a support plate arranged on the inner wall of the cabinet, an oiling robotic arm arranged on the top of the support plate, a drying box with a drying system arranged on one side of the cabinet, an adaptive clamping structure arranged on the upper surface of the support plate, a pipe connecting assembly and a flipping assembly, and a drying assembly arranged inside the drying box. The adaptive clamping structure includes a plurality of outer shells arranged in a ring array above the support plate that can be brought together, push rods that are all slidably and sealingly adapted to the interior of the plurality of outer shells, and bending rods that are all hinged to one end of the plurality of push rods.

[0007] The flipping assembly includes a stabilizing frame that is slidably adapted to one end of several housings, wherein two end surfaces of the stabilizing frames are fixedly connected to flipping wheels, and several meshing rods are fixedly arranged above the bearing plate, with the protrusions on the meshing rods meshing and matching with the flipping wheels.

[0008] By using several converging outer shells and the independent translation of several push rods, the bending rod can adapt to clamping plate-shaped workpieces with complex shapes such as circles or rectangles. Simultaneously, the bending rod can provide a wrap-around clamping for thinner plate-shaped workpieces and a multi-point lifting clamping for thicker plate-shaped workpieces. Furthermore, through the meshing transmission between the flipping wheel and the protruding rod on the meshing rod, thicker plate-shaped workpieces can be flipped at right angles, and thinner plate-shaped workpieces can be turned over. This invention, through the convergence of several outer shells and the independent translation of push rods driving the bending rod's movement, is specifically adapted to the oiling clamping requirements of plate-shaped workpieces with complex shapes such as circles and rectangles, and to achieve oiling for thin plates. The wrap-around stable clamping mechanism enables multi-point lifting and clamping of thick plates during oiling, effectively solving the problem of limited adaptability and difficulty in stably supporting plate-shaped workpieces of different specifications to ensure oiling stability in traditional coating clamping structures. At the same time, relying on the meshing transmission design of the flipping wheel and the meshing rod protrusion, it can perform right-angle flipping for thick plates required for oiling and flipping for thin plates required for oiling, accurately cooperating with the oiling robotic arm to complete double-sided precise oiling of workpieces, greatly improving the adaptability and efficiency of oiling operations for plate-shaped workpieces of different specifications and shapes, and meeting the core needs of automated oiling of diverse plate-shaped workpieces.

[0009] Preferably, a slide rail is provided on the upper surface of the bearing plate.

[0010] Preferably, the adaptive clamping structure further includes a movable plate with a pneumatic slider, the movable plate being slidably connected to the upper surface of the support plate, a support plate being fixedly connected to the bottom of the movable plate, and the pneumatic slider on the movable plate slidingly adapting to the inside of the slide rail through the support plate. An annular sandwich plate is movably arranged on the top of the movable plate, and several waist-shaped grooves are formed in an annular array on the upper surface of the annular sandwich plate. A movable ring is rotatably connected inside the annular sandwich plate through an electric slider, and through holes are formed in an annular array on the upper surface of the movable ring.

[0011] Preferably, a plurality of the outer shells are arranged in a ring array and slidably connected to the surface of the ring sandwich plate by insert rods. The outer shells and the end of the push rods form a sealed cavity. Two adjacent bending rods are slidably adapted to each other by insert rods, and a conical torsion spring is fixedly connected between two adjacent bending rods.

[0012] Preferably, the pipe connection assembly includes two arc-shaped rigid pipes, which are arranged in a circular array above the moving plate, and the arc-shaped rigid pipes are connected to the outer shell through telescopic pipes.

[0013] Preferably, each of the arc-shaped rigid pipes has a first rigid pipe connected to its side surface, and the two first rigid pipes are symmetrically distributed. The first rigid pipes are rotatably and sealed to the arc-shaped rigid pipes, and each first rigid pipe has a flexible hose fixedly connected to its bottom.

[0014] Preferably, the flipping assembly further includes two hydraulic rods, which are symmetrically connected to the top of the support plate and are adapted to the surface of the output end of the first rigid tube.

[0015] Preferably, the telescopic tube is sleeved inside the stabilizer, the fixing ring on the stabilizer is sleeved on the surface of the arc-shaped rigid pipe, and a plurality of the meshing rods are fixedly connected to the top of the support plate in a symmetrical structure.

[0016] Preferably, the drying assembly includes several gears, all of which are symmetrically connected to the inner walls of both sides of the drying chamber via insert rods. Each pair of gears is adapted to each other via chain drive. Between the two chains, several holding plates are axially rotatable via mounting plates. Each holding plate has a counterweight fixedly connected to the end of the insert rod.

[0017] A method of using an automatic oiling system includes the following steps:

[0018] S1. Oiling preparation: Before oiling, the surface of the plate-shaped workpiece needs to be cleaned. At the same time, the drying system in the drying oven needs to be started in advance to preheat the inside of the drying oven and make it a dry environment.

[0019] S2. Apply oil to the workpiece;

[0020] S2.1 Workpiece clamping: The plate-shaped workpiece is placed between several shells. Then, the electric slider is moved by the external control system, which drives the movable ring to rotate. The insert rod slides inside the waist-shaped groove, causing the shells to converge towards the center. The external control system also allows gas to flow in from the hose and then from the telescopic tube into the sealed cavity formed between the shell and the push rod, causing the push rod to move horizontally. Several bending rods come into contact with the side of the workpiece and rotate axially. Thinner plate-shaped workpieces are clamped in a wrapping manner, while thicker plate-shaped workpieces are clamped at multiple points.

[0021] S2.2, Oiling the workpiece: After clamping, the moving plate with the pneumatic slider is moved horizontally by the external control system, and then the oiling robot arm adjusts the position of the oiling component to perform oiling operation on the surface of the workpiece.

[0022] S2.3, Workpiece flipping: First, the hydraulic rod drives the first rigid tube to move upward through the external control system. At this time, the side of the flipping wheel slides on the side of the meshing rod, and then rotates when it passes the upper protrusion of the meshing rod. The torque is applied to the outer shell through the stabilizer, causing the workpiece to flip. It can flip thin plate-shaped workpieces with wrap-around clamping, and perform right-angle flipping of thick plate-shaped tools with multi-point lifting clamping. The other side of the workpiece is oiled by the oiling robot arm.

[0023] S3. Workpiece Drying: The workpiece held by the workpiece is placed on the holding plate by the moving plate with the pneumatic slider, and then dried by the drying system. When the holding plate moves, the counterweight applies a force to the holding plate to keep the holding plate in a horizontal state for stability.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention utilizes the convergence of several outer shells and the independent translation of push rods to drive the bending rod's movement. It is specifically adapted to the oiling and clamping requirements of complex-shaped plate workpieces such as circles and rectangles, and provides a wrap-around stable clamping for thin plates during oiling, as well as a multi-point lifting clamping for thick plates during oiling. This effectively solves the problem of traditional coating clamping structures having limited adaptability and difficulty in stably supporting plate workpieces of different specifications to ensure oiling stability. At the same time, relying on the meshing transmission design of the flipping wheel and the meshing rod protrusion, it can perform right-angle flipping for thick plates required for oiling and flipping for thin plates required for oiling, precisely cooperating with the oiling robotic arm to complete double-sided precise oiling of the workpiece. This significantly improves the adaptability and efficiency of oiling operations for plate workpieces of different specifications and shapes, and overall meets the core requirements of automated oiling of diverse plate workpieces.

[0026] 2. This invention achieves precise clamping of plate-shaped workpieces of different thicknesses by rotating the movable ring to bring the outer shell together, combined with the independent translation of the push rod and the hierarchical design of the bending rod: for thin plates, a wrap-around clamping bending rod is used to fit and wrap the workpiece, while for thick plates, a multi-point lifting clamping push rod is used to adapt and support the workpiece, solving the problem that traditional clamping devices can only adapt to workpieces of a single specification; at the same time, a conical torsion spring assists the bending rod in fitting the workpiece, ensuring stable clamping without damaging the workpiece surface, greatly improving the system's adaptability to complex plate-shaped workpieces with irregular shapes and uneven thicknesses.

[0027] 3. This invention achieves targeted flipping for different clamping methods: it flips thin plates by wrapping them with clamps and flips thick plates by lifting them at multiple points at right angles, ensuring the stability of the workpiece flipping posture; the arc-shaped rigid pipe and telescopic pipe design of the pipe connection component avoids pipe entanglement or interference during flipping, and combined with the multi-angle operation capability of the oiling robot arm, it realizes continuous operation of double-sided oiling of the workpiece, solving the problems of conflict between traditional flipping mechanisms and pipes and low efficiency of double-sided oiling.

[0028] 4. In this invention, the stabilizing frame provides rigid support for the arc-shaped pipe and the outer shell, preventing deformation of the flexible pipe during driving; the rotary sealing design of the pipe connecting component ensures stable gas delivery and guarantees precise execution of clamping and flipping actions; the sliding cooperation between the moving plate and the slide rail enables smooth transfer of the workpiece between clamping, oiling, flipping, and drying stations; the various structures, through mechanical linkage and pneumatic and electric control coordination, reduce the risk of jamming and interference during operation, lower the probability of equipment failure, and adapt to the continuous operation requirements of automated production lines.

[0029] 5. This invention uses gears and chains to drive a tray to transport workpieces. A counterweight ensures the tray remains level during movement, preventing workpiece slippage or tilting that could lead to uneven drying. Oiled workpieces can be directly moved into the drying chamber via a movable plate, achieving seamless integration of the oiling and drying processes. Compared to traditional drying methods that require manual workpiece transfer, this design reduces process intervals, and the horizontal transport ensures uniform curing of the oil film during drying, improving the stability and efficiency of post-oiling treatment.

[0041] like Figures 1-5 , Figure 7 and Figures 9-10 As shown, the present invention relates to an automatic oiling system, comprising a cabinet 1, a support plate 11 arranged on the inner wall of the cabinet 1, a slide rail 111 formed on the upper surface of the support plate 11, an oiling robotic arm 12 arranged on the top of the support plate 11, a drying chamber 2 with a drying system arranged on one side of the cabinet 1, an adaptive clamping structure 3 arranged on the upper surface of the support plate 11, a pipe connecting assembly 4 and a flipping assembly 5, and a drying assembly 6 arranged inside the drying chamber 2.

[0042] It is worth noting that the robotic arm in the oiling robotic arm 12 is a conventional technology and will not be described in detail again. Its output end consists of an oil delivery system, a drive system and an oiling system, which can perform oiling operations on workpieces at complex angles.

[0043] The clamping structure 3 includes a movable plate 31 with a pneumatic slider. The movable plate 31 is slidably connected to the upper surface of the support plate 11. A support plate 32 is fixedly connected to the bottom of the movable plate 31, and the pneumatic slider on the movable plate 31 slides through the support plate 32 and is adapted to the inside of the slide rail 111. An annular sandwich plate 33 is movably arranged on the top of the movable plate 31. Several waist-shaped grooves 331 are formed in an annular array on the upper surface of the annular sandwich plate 33. A movable ring 34 is rotatably connected inside the annular sandwich plate 33 via an electric slider. The upper surface of the movable ring 34... The annular sandwich plate 33 has through holes 341 arranged in a ring. Several outer shells 35 are slidably connected to the upper surface of the annular sandwich plate 33 by insert rods. The insert rods on the outer shells 35 pass through the waist-shaped grooves 331 and the through holes 341. Each outer shell 35 is slidably sealed with a push rod 36 inside. The outer shell 35 and the end of the push rod 36 form a sealed cavity. Several bent rods 37 are hinged to one end of each push rod 36. Adjacent bent rods 37 are slidably fitted by insert rods. A conical torsion spring 38 is fixedly connected between adjacent bent rods 37.

[0044] Specifically, the movable ring 34 is driven by an electric slider to rotate inside the annular sandwich plate 33, causing several outer shells 35 to converge, which can accommodate the oiling and clamping of various plate-shaped workpieces of different specifications. Furthermore, by inputting or venting gas into the sealed cavity inside the outer shell 35, several push rods 36 can move independently to adapt to the shape of the plate-shaped workpiece. At the same time, several layers of falling bending rods 37 can provide a wrapping clamping for thinner plate-shaped workpieces and a multi-point lifting and clamping for thicker plate-shaped workpieces.

[0045] This invention achieves precise clamping of plate-shaped workpieces of different thicknesses by rotating the movable ring 34 to bring the outer shell 35 together, combined with the independent translation of the push rod 36 and the hierarchical design of the bending rod 37: for thin plates, the bending rod 37 is used to wrap around and hold them, while for thick plates, the push rod 36 is used to support and adapt to multiple points, solving the problem that traditional clamping devices can only adapt to workpieces of a single specification; at the same time, the conical torsion spring 38 assists the bending rod 37 in fitting the workpiece, ensuring stable clamping without damaging the workpiece surface, and greatly improving the system's adaptability to complex plate-shaped workpieces with irregular shapes and uneven thicknesses.

[0046] like Figure 4 and Figure 6 As shown, the pipe connection assembly 4 includes two arc-shaped rigid pipes 41, which are arranged in a ring array above the movable plate 31. The arc-shaped rigid pipes 41 are connected to the outer shell 35 through a telescopic pipe 42. Each arc-shaped rigid pipe 41 has a first rigid pipe 43 connected to its side surface, and the two first rigid pipes 43 are symmetrically distributed. The first rigid pipes 43 are rotatably and sealed to the arc-shaped rigid pipes 41. Each first rigid pipe 43 has a flexible hose 44 fixedly connected to its bottom.

[0047] Specifically, by forming two arc-shaped rigid pipes 41 that can be flipped and whose rotational axial positions correspond to each other by connecting pipes on several outer shells 35, problems such as interference of the movement of several connecting pipes can be avoided when the workpiece is flipped, thus avoiding affecting the oiling operation on the flipped surface of the workpiece.

[0048] This invention enables targeted flipping for different clamping methods: it flips thin plates using a wrap-around clamping method and flips thick plates using a right-angle lifting method, ensuring stable workpiece flipping posture. The arc-shaped rigid pipe 41 and telescopic pipe 42 design of the pipe connecting component 4 avoid pipe entanglement or interference during flipping. Combined with the multi-angle operation capability of the oiling robot arm 12, it realizes continuous operation of double-sided oiling of workpieces, solving the problems of conflict between traditional flipping mechanisms and pipes and low efficiency of double-sided oiling.

[0049] like Figure 4 , Figure 6 and Figure 8 As shown, the flipping assembly 5 includes several stabilizing frames 51, each of which is slidably fitted onto one end of the housing 35. A telescopic tube 42 is sleeved inside the stabilizing frame 51, and a fixing ring on the stabilizing frame 51 is sleeved onto the surface of the arc-shaped rigid pipe 41. Two of the stabilizing frames 51 have flipping wheels 52 fixedly sleeved on their end surfaces. The top of the support plate 32 is symmetrically connected to a hydraulic rod 53, which is adapted to the output end surface of the first rigid pipe 43. The top of the support plate 32 is symmetrically connected to a meshing rod 54, and the protrusion on the meshing rod 54 meshes with the flipping wheel 52 for transmission.

[0050] It is worth noting that by using the stabilizer 51 to stably connect the arc-shaped rigid pipe 41 to the outer casing 35, the hydraulic rod 53 applies force to the arc-shaped rigid pipe 41, and the flexible characteristics of the telescopic pipe 42 will not prevent the outer casing 35 and its lower components from moving.

[0051] Specifically, the hydraulic rod 53 causes the stabilizer 51 to move the outer shell 35 and its supporting components below it. When flipping a thicker plate-shaped workpiece, the thicker plate-shaped workpiece is flipped at a right angle because a multi-point lifting and clamping method is used. The upper protrusion of the meshing rod 54 engages with the flipping wheel 52 for transmission. When flipping a thinner plate-shaped workpiece, the thinner plate-shaped workpiece is flipped because a wrapping clamping method is used. The upper protrusion of the meshing rod 54 engages with the flipping wheel 52 for transmission.

[0052] In this invention, the stabilizing frame 51 provides rigid support for the arc-shaped pipe and the outer shell 35, preventing deformation of the flexible pipe during driving; the rotary sealing design of the pipe connecting component 4 ensures stable gas delivery and guarantees precise execution of clamping and flipping actions; the sliding cooperation between the moving plate 31 and the slide rail 111 enables smooth transfer of the workpiece between clamping, oiling, flipping, and drying stations; through mechanical linkage and pneumatic and electric control coordination, the various structures reduce the risk of jamming and interference during operation, lower the probability of equipment failure, and adapt to the continuous operation requirements of automated production lines.

[0053] like Figure 3 As shown, the drying assembly 6 includes several gears 61, all of which are symmetrically connected to the inner walls of both sides of the drying chamber 2 via insert rods. Each pair of gears 61 is driven and matched by a chain 62. Between the two chains 62, several holding plates 63 are axially rotatable via mounting plates. Each holding plate 63 has a counterweight 64 fixedly connected to the end of the insert rod.

[0054] This invention uses gears 61 and chains 62 to drive a holding plate 63 to transport workpieces. A counterweight 64 ensures the holding plate 63 remains horizontal during movement, preventing workpiece slippage or tilting that could lead to uneven drying. The oiled workpiece can be directly transferred into the drying chamber 2 via a moving plate 31, achieving seamless integration of the oiling and drying processes. Compared to traditional drying methods that require manual workpiece transfer, this design reduces process intervals, and the horizontal transport ensures uniform curing of the oil film during drying, improving the stability and efficiency of post-oiling treatment.

[0055] A method of using an automatic oiling system includes the following steps:

[0056] S1. Oiling preparation: Before oiling, the surface of the plate-shaped workpiece needs to be cleaned. At the same time, the drying system in the drying oven 2 needs to be started in advance to preheat the inside of the drying oven 2 and make it a dry environment.

[0057] S2. Apply oil to the workpiece;

[0058] S2.1 Workpiece clamping: The plate-shaped workpiece is placed between several outer shells 35. Then, the electric slider is moved by the external control system, which drives the movable ring 34 to rotate. The insert rod slides inside the waist-shaped groove 331, causing the several outer shells 35 to converge towards the center. The external control system also allows gas to flow in from the hose 44 and from the telescopic tube 42 into the sealed cavity formed between the outer shell 35 and the push rod 36, causing the push rod 36 to translate. Several bending rods 37 come into contact with the side of the workpiece and rotate axially. Thinner plate-shaped workpieces are clamped in a wrapping manner, while thicker plate-shaped workpieces are clamped at multiple points.

[0059] S2.2, Oiling the workpiece: After clamping, the moving plate 31 with pneumatic slider is moved horizontally by the external control system, and then the oiling robot arm 12 adjusts the position of the oiling component to perform oiling operation on the surface of the workpiece.

[0060] S2.3, workpiece flipping: First, the hydraulic rod 53 drives the first rigid tube 43 to move upward through the external control system. At this time, the side of the flipping wheel 52 slides on the side of the meshing rod 54, and then rotates when it passes the upper protrusion of the meshing rod 54. The torque is applied to the outer shell 35 through the stabilizer 51, causing the workpiece to flip. It can flip thin plate-shaped workpieces with wrap-around clamping and perform right-angle flipping of thick plate-shaped tools with multi-point lifting clamping. The other side of the workpiece is oiled by the oiling robot arm 12.

[0061] S3. Workpiece drying: The workpiece held by the movable plate 31 with pneumatic slider moves horizontally on the support plate 11 and is placed on the holding plate 63. The workpiece is then dried by the drying system. When the holding plate 63 moves, the counterweight 64 applies a force to the holding plate 63, so that the holding plate 63 is always in a horizontal state for stability.

[0062] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.

10. The method of using an automatic oiling system according to claim 9, characterized in that, Includes the following steps: S1. Oiling preparation: Before oiling, the surface of the plate workpiece needs to be cleaned. At the same time, the drying system in the drying oven (2) needs to be started in advance to preheat the inside of the drying oven (2) so that the inside is in a dry environment. S2. Apply oil to the workpiece; S2.1, workpiece clamping: The plate-shaped workpiece is placed between several shells (35), and then the electric slider is moved by the external control system, which drives the movable ring (34) to rotate. The insert rod slides inside the waist groove (331), causing several shells (35) to gather in the middle. The gas flows in from the hose (44) and from the telescopic tube (42) into the sealed cavity formed between the shell (35) and the push rod (36), causing the push rod (36) to translate. Several bending rods (37) come into contact with the side of the workpiece and rotate axially. The thinner plate-shaped workpiece is clamped in a wrapping manner, and the thicker plate-shaped workpiece is clamped at multiple points. S2.2, Oiling the workpiece: After clamping, the moving plate (31) with pneumatic slider is moved horizontally by the external control system, and then the oiling robot arm (12) adjusts the position of the oiling component to perform oiling operation on the surface of the workpiece. S2.3, workpiece flipping: First, the hydraulic rod (53) drives the first rigid tube (43) to move upward through the external control system. At this time, the side of the flipping wheel (52) slides on the side of the meshing rod (54) and then rotates when it passes the protrusion on the meshing rod (54). The torque is applied to the outer shell (35) through the stabilizer (51), causing the workpiece to flip. It can flip thin plate-shaped workpieces with wrap-around clamping and perform right-angle flipping of thick plate-shaped tools with multi-point lifting clamping. The other side of the workpiece is oiled by the oiling robot arm (12). S3. Workpiece drying: The workpiece held by the movable plate (31) with pneumatic slider is moved on the support plate (11) and placed on the holding plate (63). The workpiece is then dried by the drying system. When the holding plate (63) moves, the counterweight (64) applies a force to the holding plate (63) so that the holding plate (63) is always in a horizontal state for stability.
