Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to an adaptive conveying device for transferring anodized paint from aircraft parts. Background Technology

[0002] In the aerospace manufacturing industry, a large number of small aluminum alloy structural parts, standard connectors, and precision sheet metal parts need to undergo surface painting. The matching topcoat meets the requirements for protection, marking, and appearance, which is the core pre-processing process for aircraft parts production. The industry generally uses overhead conveyor lines to complete the continuous transfer of workpieces across processes, realizing the flow of workpieces without hanging them down, reducing the problems of bumps, scratches, and rework caused by multiple loading and unloading, and improving production continuity. However, although the existing overhead conveyor system can realize aerial transfer, it has many inherent defects in terms of conveyor line expansion, power supply, adaptive clamping, and online reversing spraying of workpieces for the complex working conditions of anodizing and painting of small aviation parts. It is difficult to meet the modern production needs of multi-specification mixed production, high-quality spraying, and low-cost flexible transformation. For example, most of the current mainstream suspended conveyor rails are integrated welded rails, which cannot be flexibly adjusted; traditional conductive rails are installed synchronously with the conveyor rails and cannot be independently disassembled or spliced ​​in sections. When the production line is modified, the conductive system needs to be replaced as a whole, which has poor versatility; existing spraying hangers are mostly fixed single hooks and simple U-shaped brackets, which have extremely poor adaptability and are difficult to be compatible with various irregularly shaped small aerospace parts.

[0013] Preferably, the three sets of power supply units are used to connect the neutral wire, the live wire, and the ground wire, respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The conveyor structure adopts a modular splicing design, with an L-shaped first conveyor frame as the corner base and a rectangular second conveyor frame as the straight extension section. Connection is achieved through bolts and mounting slots. The length and width of the conveyor line can be adjusted according to workshop site conditions and process layout requirements, eliminating the need for customized integrated welded tracks, thus reducing the construction difficulty and material costs of production line setup and modification. The closed-loop conveyor belt drives the suspended structure for cyclical transport. The equidistantly arranged suspended structures do not interfere with each other during operation, ensuring stable conveying. The entire system is installed using suspended rods mounted on the ceiling, making full use of the upper space of the workshop and reducing the occupation of the ground work area.

[0015] 2. The power supply structure and the conveying structure are set up independently. The conductive rails also adopt the form of segmented splicing of corner sections and straight sections. The number of sections and the size can be increased or decreased synchronously with the adjustment of the conveying line. When the production line is modified, there is no need to replace the entire power supply system, which makes it more versatile. The three sets of power supply units are stacked in layers, corresponding to the neutral wire, live wire and ground wire respectively. The power supply circuit is clear. With the help of the insulating frame to isolate the conductive parts and the hoisting structure, the electrical safety can be improved. The conductive rails are connected by inserting conductive connecting rods and tightening bolts. The disassembly and assembly operations are convenient, and it is easy to inspect and replace local parts.

[0016] 3. The suspension assembly allows for adjustment of the distance between the second booms on both sides via an electric slide rail. Combined with an I-shaped mounting bracket that can slide and adjust its position along a semi-circular adjustment groove, it can accommodate the clamping needs of small aircraft parts of different sizes and shapes. The rubber clamping arms are opened and closed by an electric push rod, employing a flexible clamping method to reduce the risk of indentation and deformation on the surface of thin-walled aluminum alloy workpieces during clamping. Simultaneously, dual motors can drive the drive disc to rotate the entire workpiece, allowing for workpiece flipping and reversal during transport without needing to remove the workpiece mid-transport for clamping angle adjustments. This helps improve the continuity of the oxidation and painting processes, reduces scratches and bumps caused by repeated loading and unloading of workpieces, and improves the uniformity of the coating surface coverage.

[0017] 4. The power connection components adopt a spring-loaded elastic contact structure, ensuring that the contact seat remains in contact with the conductive rail during the conveyor's movement, thus guaranteeing the continuity and stability of power supply. The insulating seat can be adjusted in height along the lifting groove to accommodate different conductive rail installation heights, resulting in good installation adaptability. All functional modules of the device adopt a detachable splicing structure, allowing individual parts to be replaced individually if damaged, without the need to scrap the entire structure, which helps reduce the cost of daily operation and maintenance.

Detailed Implementation

[0020] The following will refer to the appendices in the embodiments of the present invention. Figures 1-11 For further details: like Figure 1 As shown, the present invention provides a technical solution: an adaptive transmission device for the transfer of anodized paint on aircraft parts, comprising a conveying structure 1, a power supply structure 2, and a suspension structure 3. The conveying structure 1 is disposed on the roof, and the suspension structure 3 is disposed above the conveying structure 1 and corresponds to each other. The suspension structures 3 are equidistantly disposed on the conveying structure 1. The conveying structure 1 is used to realize the belt conveying of the rectangular frame line, avoid the suspension structures 3 from colliding with each other, and can adjust the laying of the line length and width. The power supply structure 2 is disposed above the conveying structure 1 and can fit the size of the conveying structure 1. The suspension structure 3 is used to fit and support small workpieces of different shapes and can change direction during conveying to realize the replacement of the sprayed wall surface.

[0021] like Figure 2 and Figure 3As shown, further, the conveying structure 1 includes two pairs of first conveyor frames 10, several second conveyor frames 11, several first bolts 12, several first nuts 13, two pairs of first lifting rods 14, two pairs of second nuts 15, two pairs of conveyor wheels 16, and a conveyor belt 17; the two pairs of first conveyor frames 10 are all right-angled L-shaped, and the two pairs of first conveyor frames 10 are located opposite each other at the four corners; the several second conveyor frames 11 are all rectangular, and mounting grooves 4 are symmetrically arranged at both ends; the two ends of the several second conveyor frames 11 can respectively dock with the two ends of the first conveyor frames 10, and the two ends of the second conveyor frames 11 can be alternately docked vertically; several first lifting holes are equidistantly arranged in the middle of the several second conveyor frames 11; several first bolts 12 respectively movably pass through the two ends of the first conveyor frames 10, and the first bolts 12 respectively movably pass through the mounting grooves 4 of the second conveyor frames 11; several first nuts 13 are respectively screwed onto the first bolts 12 and are located below the second conveyor frames 11; one end of each of the two pairs of first lifting rods 14 movably passes through... Two pairs of second conveyor frames 11 have first lifting holes, and first lifting rods 14 are located near the four corners. Two pairs of second nuts 15 are screwed onto the first lifting rods 14, and the second nuts 15 are located on the upper wall of the second conveyor frame 11 for fixation. Two pairs of conveyor wheels 16 are movably set in the middle of the two pairs of first conveyor frames 10, and conveyor belts 17 are movably fitted between the conveyor wheels 16. The corners of the conveyor line are built by using L-shaped first conveyor frames 10 at the four corners. Multiple rectangular second conveyor frames 11 are alternately connected and spliced ​​in the middle. The first bolts 12 pass through the mounting grooves 4 at the joints and are locked with the first nuts 13 to form a complete rectangular conveyor frame. The first lifting rods 14 pass through the lifting holes of the second conveyor frames 11, and the entire frame is hoisted and fixed to the workshop ceiling by the second nuts 15. Conveyor wheels 16 are installed in the middle of the four corner first conveyor frames 10. The conveyor belts 17 surround the two sets of conveyor wheels 16 to form a closed-loop transmission track. The suspension mechanism for hanging the workpiece moves cyclically with the conveyor belts 17 to complete the continuous transfer of the workpiece.

[0022] More specifically, the conveyor structure 1 adopts a modular splicing structure. Two pairs of right-angled L-shaped first conveyor frames 10 serve as corner bases. Several rectangular second conveyor frames 11 with mounting slots 4 at both ends are connected alternately to form straight segments. After being locked with first bolts 12 and first nuts 13, a complete rectangular conveyor frame is formed. The length and width of the conveyor line can be flexibly adjusted to adapt to different workshop layouts and production line transformation needs without the need to replace the entire integrated track. The whole structure is hoisted and fixed to the roof by two pairs of first hanging rods 14 and second nuts 15, effectively utilizing the upper space of the workshop and reducing the occupation of the ground work area. Two pairs of conveyor wheels 16 support the conveyor belt 17 to form a closed-loop transmission path, which can drive the suspension structure to move smoothly along the line and realize continuous transfer of workpieces. Moreover, all components are detachable and can be replaced individually if damaged, resulting in low daily maintenance costs.

[0023] like Figure 4 and Figure 5 As shown, further, the power supply structure 2 includes a pair of second hangers 21, three sets of power supply units 22, and several third nuts 23. The pair of second hangers 21 are respectively set above the conveyor belt 17 and are symmetrically located on the front and rear sides of the middle of the conveyor belt 17. The three sets of power supply units 22 are respectively movably inserted through the pair of second hangers 21, and the power supply units 22 are stacked above the conveyor belt 17. The power supply units 22 are correspondingly fitted to the conveyor belt 17. Several third nuts 23 are respectively screwed onto the second hangers 21, and the third nuts 23 are respectively located on the upper and lower sides of the power supply units 22 for clamping and fixing. The two symmetrically arranged second hangers 21 are erected above the conveyor belt 17, and the three sets of power supply units 22 are inserted through the hangers and stacked. The third nuts 23 on the upper and lower sides are clamped and limited, and the entire set of power supply units 22 is fixed above the conveyor line. The power supply units 22 are matched with the stroke of the conveyor belt 17 below, and continuously provide power to the suspension mechanism moving on the conveyor belt 17.

[0024] More specifically, the power supply structure 2 adopts an overhead independent layout. It uses a pair of second hangers 21 symmetrically arranged above the conveyor belt 17 to support three stacked power supply units 22. The third nuts 23 clamp and lock the power supply units 22 from the top and bottom sides, which can make the wiring of the power supply units 22 precisely correspond to the travel path of the conveyor belt 17 below, providing a continuous power supply for the suspension mechanism that travels with the conveyor belt. The three power supply units 22 are arranged independently in layers, with clear circuit distinctions. At the same time, the overall assembly structure is flexible to disassemble and assemble, and can be adapted synchronously with the size adjustment of the conveyor line. There is no need to replace the entire power supply system, which improves the adaptability of production line transformation and the convenience of daily maintenance.

[0025] like Figure 4 and Figure 5As shown, further, the power supply unit 22 includes two pairs of first conductive rails 221, several second conductive rails 222, several conductive connecting rods 223, several fourth bolts 224, and a first insulating frame 225; both pairs of first conductive rails 221 are L-shaped, and the middle of the first conductive rails 221 has an arc-shaped structure. The two pairs of first conductive rails 221 are respectively set above the conveyor belt 17 and correspond to the first conveyor frame 10 in sequence. Both ends of the two pairs of first conductive rails 221 are provided with docking holes 5. Several second conductive rails 222 are detachably connected to both ends of the first conductive rails 221, and the second conductive rails 222 can be docked in sequence. Both ends of several second conductive rails 222 are provided with docking holes 5 the same as those of the first conductive rails 221. Several conductive connecting rods 223 are detachably inserted between the first conductive rails (221) and the second conductive rails (222) for docking connection. Several fourth bolts 224 are screwed on. The first insulating frame 225 is detachably mounted on the second conductive rail 222 between the first conductive rail 221 and the second conductive rail 222, and is pressed against the conductive connecting rod 223. The first insulating frame 225 is located above the middle of the conveyor belt 17. The first insulating frame 225 is fitted onto the second hanging rod 21 near the front and rear ends, and is fixed by the third nut 23. The L-shaped first conductive rail 221 with a central arc is arranged at the four corners of the conveyor line. The straight section is spliced ​​end to end by multiple second conductive rails 222. The conductive connecting rod 223 is inserted into the docking hole 5 of the two to complete the conductive connection. The fourth bolt 224 is pressed against the conductive connecting rod 223 to ensure reliable conduction. The first insulating frame 225 sets the entire set of conductive rails on the second hanging rod 21 and locks and positions it with the third nut 23, so that the conductive rails fit the conveyor belt 17 line as a whole, allowing the lower moving suspension mechanism to slide and draw power.

[0026] More specifically, the power supply unit 22 adopts a segmented splicing conductive rail design. The L-shaped first conductive rail 221 with an arc transition is adapted to the four corners of the conveyor line. Several second conductive rails 222 are spliced ​​together to form a straight conductive section. The two are connected by inserting the conductive connecting rod 223 into the docking hole 5 and tightened with the fourth bolt 224. This not only ensures the contact reliability of the conductive path, but also allows for flexible increase or decrease of the number of conductive rail sections according to the length of the conveyor line, making it highly adaptable. The conductive rail is mounted on the second hanging rod 21 by the first insulating frame 225, which not only achieves insulation isolation between the conductive rail and the metal hanging structure, reducing the risk of leakage, but also allows for adjustment of the fixed position with the third nut 23, so that the conductive rail path is precisely matched with the conveyor belt 17 below, ensuring the continuity of power supply for the sliding mechanism.

[0027] like Figure 6 and Figure 7As shown, the suspension structure 3 further includes a suspension assembly 31 and a power connection assembly 32; the suspension assembly 31 is fixedly mounted on the conveyor belt 17, the power connection assembly 32 is fixedly mounted on the suspension assembly 31, and the power connection assembly 32 is in contact with the power supply unit 22.

[0028] like Figure 6-7 As shown, further, the suspension assembly 31 includes a first boom 311, an electric slide rail 312, a pair of second booms 313, a pair of motors 314, a drive disc 315, two pairs of mounting brackets 316, several rubber clamps 317, and several electric push rod bodies 318; one end of the first boom 311 is fixedly mounted on the conveyor belt 17, the electric slide rail 312 is fixedly mounted on the other end of the first boom 311, and the electric slide rail 312 has relatively movable sliders symmetrically arranged at both ends; one end of each pair of second booms 313 is symmetrically arranged on the sliders at both ends of the electric slide rail 312, and the second booms 313 are positioned between each other. The distance is adjustable. A pair of motors 314 are symmetrically arranged on the other end of the second boom 313, and their drive ends correspond to each other. The drive disc 315 has a circular structure in the middle, and connecting frames are symmetrically arranged on the left and right side walls of the drive disc 315. The drive disc 315 is movably arranged between the motors 314, and the connecting frames on the side walls of the drive disc 315 are detachably fitted onto the drive ends of the motors 314. The upper wall of the drive disc 315 has a semi-circular first adjustment groove 6 symmetrically opened in the middle. Both pairs of mounting brackets 316 are I-shaped structures with four ends. One end of each pair of mounting brackets 316 movably passes through the first adjustment groove 6. 16 can move along the first adjusting groove 6. Each of the two pairs of mounting brackets 316 is screwed with a fifth bolt 8, which presses against the side wall of the drive disc 315. Several rubber clamping arms 317 are movably connected at one end to two ends of the mounting bracket 316, and the rubber clamping arms 317 correspond to the other two ends of the mounting bracket 316. Several electric push rod bodies 318 are movably connected at one end to the side walls of the other two ends of the mounting bracket 316, and the telescopic end of the electric push rod body 318 can be tilted and movably connected to the other side wall of the rubber clamping arm 317. The electric push rod body 318 is located between the rubber clamping arm 317 and the mounting bracket. Between the other two ends of 316; the first boom 311 moves synchronously with the conveyor belt 17; the electric slide rail 312 drives the sliders on both sides to adjust the distance between the second boom 313 to adapt to workpieces of different widths; the motors 314 on both sides clamp the drive disk 315 and can drive it to rotate; the I-shaped mounting bracket 316 can slide along the semi-circular adjustment groove of the drive disk 315 to adjust its position, and the fifth bolt 8 is locked and fixed; the electric push rod tilts and pushes and pulls the rubber clamping arm 317, and the workpiece is clamped by multiple sets of rubber clamping arms 317 to achieve adaptive clamping of the workpiece, and the motor 314 drives the drive disk 315 to rotate, which can drive the workpiece to change direction for spraying.

[0029] More specifically, the suspension assembly 31 is fixed to the conveyor belt 17 via the first boom 311 for synchronous conveying. The spacing between a pair of second booms 313 can be adjusted by the electric slide rail 312. With the help of the I-shaped mounting bracket 316 which can slide and be positioned along the semi-circular first adjustment groove 6 on the drive disc 315, the clamping span and clamping point can be flexibly adjusted to meet the clamping needs of small aircraft parts of different sizes and shapes. The rubber clamping arm 317 is opened and closed by the tilting drive of the electric push rod body 318. The flexible clamping method can reduce the risk of indentation and surface scratches on thin-walled aluminum alloy workpieces. At the same time, the motors 314 on both sides can drive the drive disc 315 and the clamped workpiece to rotate as a whole. The workpiece can be flipped and changed during the conveying process without having to go offline to adjust the clamping posture. This helps to improve the continuity of the oxidation and painting processes and the uniformity of the surface treatment. Moreover, the core components such as the drive disc and mounting bracket adopt a detachable assembly structure. Local damage can be replaced individually, which facilitates daily maintenance and reduces maintenance costs.

[0030] like Figure 6 and Figure 7 As shown, further, the power connection assembly 32 includes a second insulating frame 321, three insulating seats 322, several sixth bolts 323, several telescopic screws 324, several contact seats 325, and several springs 326. One end of the second insulating frame 321 is fixedly mounted on the first boom 311, and the second insulating frame 321 is located outside the second conductive rail 222. The other end of the second insulating frame 321 is symmetrically provided with lifting grooves 7. The three insulating seats 322 are detachably mounted on the other end of the second insulating frame 321. Several sixth bolts 323 respectively movably pass through the lifting grooves 7 of the second insulating frame 321 and are screwed into the side wall of one end of the insulating seat 322 for fixation. Several telescopic screws 324 respectively symmetrically move through the insulating seats 322. Several contact seats 325 are respectively... The first insulating bracket 321 is fixed between the telescopic screws 324 and located below the insulating base 322. Several contact seats 325 can contact the second conductive rail 222 respectively. Several springs 326 are movably mounted on the telescopic screws 324 and located between the contact seats 325 and the insulating base 322. The second insulating bracket 321 is fixed on the first boom 311 and faces the conductive rail. The insulating base 322 can be adjusted up and down along the lifting groove 7 and then locked with the sixth bolt 323. The lower end of the telescopic screw 324 is equipped with contact seats 325. The springs 326 are sleeved on the screw. The contact seats 325 are pressed down by the elastic force of the springs 326, so that the contact seats 325 are always in close contact with the upper conductive rail and continuously slide to draw power. The three sets of insulating bases 322 correspond to the neutral, live and ground wires of the three conductive rails for independent contact power supply.

[0032] Furthermore, the contact seat 325 can be moved upwards and compressed by the telescopic screw 324 through the insulating seat 322 to compress the spring 326, so that the contact seat 325 can fully contact the first conductive rail 221 and the second conductive rail 222; the mounting bracket 316 is symmetrically provided with rubber clamping arms 317 and electric push rod body 318 at both ends, which can be used for flipping and reversing, or set in one direction to save costs; the three power supply units 22 are respectively used to connect the neutral wire, the live wire and the ground wire.

[0033] Working principle: First, this equipment is divided into three main modules: conveying structure 1, power supply structure 2, and suspension structure 3. All three are installed overhead on the ceiling of the paint shop. The three work together to complete the adaptive clamping of small aerospace parts, stable power supply, closed-loop continuous transfer, and online reversing spraying operations. The workflow is as follows: Two pairs of L-shaped first conveyor frames 10 are arranged at the four corners of the conveying line as corner bases, and multiple rectangular second conveyor frames 11 are used as straight extension sections. Mounting slots 4 are opened at both ends of the second conveyor frames 11. The first bolts 12 pass through the end of the first conveyor frame 10 and the mounting slots 4 of the second conveyor frame 11, and are locked with the first nuts 13. Multiple second conveyor frames 11 are alternately connected to form a rectangular conveying frame whose length and width can be freely adjusted. The second conveyor frame 11 near the four corners has a first lifting hole. The first lifting rod 14 passes through the lifting hole, and the second nut 15 is tightened on the upper wall of the second conveyor frame 11 to hoist and fix the entire conveyor frame to the roof. Two pairs of conveyor wheels 16 are respectively assembled in the middle of the first conveyor frame 10 at the four corners. The conveyor belt 17 surrounds the two sets of conveyor wheels 16 to form a closed-loop transmission belt. The conveyor belt 17 continuously circulates and drives all the suspension structures 3 on it to move synchronously, so as to realize the continuous transfer of workpieces along the rectangular line. The power supply structure 2 is erected above the conveyor belt 17 to provide three-line power to the moving mechanism. A pair of second hangers 21 are symmetrically arranged above the middle of the conveyor belt 17. Three sets of power supply units 22 are stacked on the second hangers 21. The third nuts 23 are locked on the upper and lower sides of the power supply unit 22 respectively to complete the overall clamping and fixing of the power supply unit 22. The wiring of the power supply unit 22 is completely matched with the wiring of the conveyor belt 17 below. A single power supply unit 22 is arranged at the corner of the line via an L-shaped first conductive rail 221 with an arc in the middle. The straight section is extended by several second conductive rails 222. Both the first conductive rail 221 and the second conductive rail 222 have docking holes 5 at their ends. The conductive connecting rod 223 is inserted into the docking hole 5 to achieve conductive connection between the two rails. The fourth bolt 224 is tightened from the inside of the rail to the conductive connecting rod 223 to ensure a firm conductive contact. The first insulating frame 225 is mounted on the second conductive rail 222 at both ends, and is also fitted onto the second hanging rod 21 and locked by the third nut 23. The first insulating frame 225 isolates the conductive rail from the metal hanging rod to prevent leakage. The three sets of power supply units 22 correspond to the neutral wire, live wire and ground wire three conductive circuits respectively. The suspension structure 3 moves synchronously with the conveyor belt, and the suspension assembly 31 and the power connection assembly 32 work together. The bottom end of the first boom 311 is fixed to the surface of the conveyor belt 17 and moves synchronously with the conveyor belt. An electric slide rail 312 is installed at the top. The sliders at both ends of the slide rail can slide relative to each other. A pair of second booms 313 are fixed on the sliders respectively. The distance between the two second booms 313 can be adjusted by extending and retracting the electric slide rail 312 to adapt to workpieces of different widths. A motor 314 is installed at the end of each of the two second booms 313. The drive ends of the two motors 314 are connected to clamp the annular drive disk 315. A semi-circular first adjustment groove 6 is opened on the top surface of the drive disk 315. One end of the two pairs of I-shaped mounting brackets 316 passes through the first adjustment groove 6 and can slide along the groove to adjust the clamping position. After the adjustment is completed, the fifth bolt 8 is tightened to tighten the drive disk 315 to achieve positioning. Each mounting bracket 316 is equipped with rubber clamping arms 317 and electric push rod body 318 at its four ends respectively; the electric push rod body 318 is inclined to connect the rubber clamping arms 317, and the push rod extends and retracts to pull the rubber clamping arms 317 to open and close. Multiple sets of rubber clamping arms 317 work together with flexible support to clamp irregularly shaped aircraft parts, and the rubber material avoids scratching the surface of the workpiece. The two motors 314 synchronously drive the drive disk 315 to rotate as a whole, which in turn drives the mounting frame 316, rubber clamping arm 317 and the workpiece to rotate together, completing the workpiece flipping during the conveying process and eliminating spraying dead corners. The power receiving component 32 continuously supplies power to the suspension component by elastically fitting the first conductive rail 221 and the second conductive rail 222; one end of the second insulating frame 321 is fixed to the first boom 311, and the whole extends to the outside of the conductive rail of the power supply unit 22; a lifting groove 7 is opened at the far end of the second insulating frame 321, and three insulating seats 322 are locked through the lifting groove 7 by the sixth bolt 323, and the height of the insulating seats 322 can be adjusted up and down along the lifting groove 7 to adapt to the conductive installation height; A telescopic screw 324 is inserted inside each insulating base 322. The lower end of the screw is fixed to the contact base 325. A spring 326 is fitted outside the telescopic screw 324 and sandwiched between the insulating base 322 and the contact base 325. The spring 326 continuously applies downward pressure to the contact base 325, so that the contact base 325 is always in close contact with the first conductive rail 221 and the second conductive rail 222 above. When the conveyor belt 17 drives the suspension structure 3 forward, the three sets of contact seats 325 respectively contact the neutral, live and ground conductive rails, continuously draw power through the sliding mechanism, and transmit the power to the electric slide rail 312, motor 314 and electric push rod body 318 to ensure stable operation of clamping, pitch adjustment and rotation actions; the second insulating frame 321 and insulating seat 322 isolate the conductive parts from the metal boom to eliminate the risk of leakage. In summary, the overall collaborative workflow of this invention is summarized as follows: The conveying structure 1 is spliced ​​to form a rectangular closed-loop track and is circulated and driven by the conveyor belt 17; the power supply structure 2 is erected above the track with a three-line modular conductive rail; the suspension structure 3 on the conveyor belt 17 moves with the track, and the power connection component 32 relies on the elastic contact of the spring with the conductive rail to continuously draw power; the power supply is supplied to the suspension component 31, which relies on the electric slide rail 312 to adjust the clamping span, the electric push rod body 318 to drive the rubber clamping arm 317 to adaptively clamp various small aircraft parts, and the motor 314 drives the workpiece to rotate and flip online. The workpiece is transported in the air throughout the process, completing the continuous operation of the oxidation and painting process.
