Description

Technical Field

[0001] The invention belongs to the technical field of aviation accessories production, and in particular relates to an aviation display frame hanging conveyor and a coating production line. Background Art

[0002] Secondary coating (also called recoating) of aviation display frames is a key process in their production, which aims to enhance the corrosion resistance, wear resistance and appearance quality of the frames to meet the aviation industry's stringent requirements for high reliability and adaptability to extreme environments.

[0003] At present, the main steps for secondary coating of aviation display frames are as follows: 1) Cleaning and degreasing: Use professional cleaning agents to thoroughly clean the surface of the frame to remove grease, dirt, old paint film, etc. This usually involves cleaning with solvents to remove all attachments. After cleaning, ensure that the surface of the frame is completely dry and there is no residual moisture or cleaning agent. 2) Primer coating: Apply a layer of primer, which should have good adhesion and rust resistance. Ensure that the primer is evenly applied to avoid sagging and missing coating. Wait for the primer to be completely dry and cured. 3) Topcoat coating: Select suitable dipping materials according to specific needs, considering their corrosion resistance, wear resistance, temperature resistance, and color. Prepare a dipping tank, ensure that the tank is clean and free of impurities, and adjust the temperature and viscosity of the dipping solution to the optimal state. Slowly immerse the pre-treated frame into the dipping tank to ensure that all parts to be painted are evenly contacted with the dipping solution. Maintain a certain dipping time to allow the dipping solution to fully penetrate the surface of the frame. Place the dipping frame in a well-ventilated area to allow the dipping solution to flow naturally. According to the requirements of the impregnation material, bake or dry naturally to promote the curing and cross-linking reaction of the paint film. Store the qualified frames properly to avoid scratches, pollution or physical damage. If necessary, package the frames for transportation or further assembly.

[0004] Suspension conveyors are commonly used equipment in painting production lines in the aviation parts production industry. Traditional suspension conveyors for painting aviation display frames were found to have shortcomings during use. First, the design of its suspension conveying system is unreasonable, and it cannot drive the aviation display frame to rotate and rise and fall during the cleaning and degreasing, primer coating, and topcoat coating process, affecting the effects of cleaning and degreasing, primer coating, and topcoat coating; second, its degree of automation is low, and it cannot meet the needs of automated loading, cleaning and degreasing, primer coating, topcoat coating, and unloading, which is not conducive to the industrial batch processing of aviation display frames.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] like Figure 1 and Figure 2 As shown, this embodiment provides an aviation display frame suspended conveyor, which includes a slider 11, an annular slide rail 12, an annular conveyor belt 13, a rectangular rack 14 and a clamping device 15. The slider 11 is slidably restricted on the annular slide rail 12, and the inner area of ​​the annular slide rail 12 is installed with an annular conveyor belt 13 for driving the slider 11 to move. The outer lower area of ​​the annular slide rail 12 is installed with a rectangular rack 14, and the clamping device 15 is installed on the side of the slider 11 away from the annular conveyor belt 13.

[0047] like Figure 3 and Figure 4 As shown, the coating object of this embodiment is an aviation display frame, and the aviation display frame 6 includes a rectangular frame 61, and the panel and bottom plate of the rectangular frame 61 are provided with a rectangular groove 62 for installing the display, and the panel of the rectangular frame 61 is provided with a key groove 63 around the rectangular groove 62, and the bottom plate of the rectangular frame 61 is symmetrically provided with opening grooves 64 on both sides of the rectangular groove 62, and the bottom plate of the rectangular frame 61 is provided with a plurality of key fixing holes 65, and the positions of the key fixing holes 65 are matched with the positions of the key grooves 63, and the side plate of the rectangular frame 61 is provided with heat dissipation through holes 66. During the hanging and coating process, the bottom plate of the aviation display frame 6 faces upward and the panel faces downward.

[0048] like Figure 5 As shown, the rectangular rack 14 is provided with arc segments at the four corners, the rectangular rack 14 is provided with convex teeth evenly distributed on the outside of the long side segment parallel to the straight segment of the endless conveyor belt 13, the rectangular rack 14 is provided with a smooth segment without convex teeth on the outside of the short side segment and the arc segment, and the inner side surface of the rectangular rack 14 serves as a fixed connection surface of its supporting carrier.

[0049] like Figure 6As shown, the clamping device 15 includes a mounting frame 151, a first vertical push rod 152, a first smooth ring, a first vertical shaft 153, a first gear ring 154, a groove seat 155, an upper pressure plate 156, a lower pressure plate 157, a positioning boss 158 and a first lifting and flipping mechanism 159. The upper side end of the mounting frame 151 is provided with a groove clamping plate for conveniently clamping it on the outer side of the slider 11, and the groove clamping plate and the slider 11 are fixedly connected by bolts. The first vertical push rod 152 is installed on the upper part of the mounting frame 151, and the movable end of the first vertical push rod 152 is connected to the top of the first vertical shaft 153 through the first smooth ring, and the bottom end of the first vertical shaft 153 is fixed to the center of the outer side of the web of the groove seat 155. The outer side of the first vertical shaft 153 is fixed with a first gear ring 154 that meshes with the convex teeth of the long side section of the rectangular rack 14. An upper pressure plate 156 is provided on the outer side of the two side plates of the groove seat 155, and a first lifting and flipping mechanism 159 for driving the lower pressure plate 157 to lift and rotate is installed in the two side plates of the groove seat 155. Positioning bosses 158 are installed on the upper sides of both ends of the lower pressure plate 157.

[0050] In this embodiment, the thickness value of the groove seat 155 in the clamping device 15 matches the groove width value of the opening groove 64 in the aviation display frame 6. When the upper pressure plate 156 and the lower pressure plate 157 in the clamping device 15 are close to each other, the bottom plate in the aviation display frame 6 can be clamped, and at the same time, the positioning boss 158 can be inserted into the button fixing holes 65 on both sides of the opening groove 64 of the bottom plate.

[0051] like Figure 7 As shown, the first lifting and flipping mechanism 159 includes a second vertical push rod 159a, a second smooth ring, a second vertical shaft 159b, a second gear ring 159c, a first rotating motor 159d and a flipping gear 159e. The movable end of the second vertical push rod 159a is connected to the top of the second vertical shaft 159b via the second smooth ring, the bottom end of the second vertical shaft 159b is fixedly connected to the center of the lower pressing plate 157, the second gear ring 159c is fixed to the outer side of the second vertical shaft 159b, and the output end of the first rotating motor 159d is installed with a flipping gear 159e meshing with the second gear ring 159c.

[0052] The working principle of the first lifting and flipping mechanism 159 is: the second vertical push rod 159a is used to drive the second vertical axis 159b and the lower pressure plate 157 to perform vertical displacement, and the axial height value of the second gear ring 159c is greater than the height value of the flipping gear 159e. When the first rotating motor 159d drives the flipping gear 159e to rotate, the second gear ring 159c can rotate accordingly, causing the lower pressure plate 157 to rotate.

[0053] The overall working principle of the clamping device 15 is as follows: when the clamping device 15 is needed to clamp the aviation display frame 6, the first vertical push rod 152 is actuated to drive the slotted seat 155 to move downward, so that the slotted seat 155 enters the opening slot 64 of the aviation display frame 6, and the upper pressure plate 156 is abutted against the upper side of the end plate of the opening slot 64. Before the slotted seat 155 moves downward, the lower pressure plate 157 is rotated in advance by the first lifting and flipping mechanism 159 to be parallel to the direction of the line connecting the two opening slots 64. After the slotted seat 155 moves downward, the first lifting and flipping mechanism 159 is used to rotate the lower pressure plate 157 to be perpendicular to the direction of the line connecting the two opening slots 64. At the same time, the first lifting and flipping mechanism 159 is used to drive the lower pressure plate 157 to move upward, so that the positioning boss 158 can be inserted into the button fixing holes 65 on both sides of the opening slot 64 of the bottom plate to complete the clamping operation. When the clamping device 15 is required to release the clamping operation of the aviation display frame 6, the first lifting and flipping mechanism 159 is used to drive the lower pressure plate 157 to move downward, and then the lower pressure plate 157 is rotated to be parallel to the direction of the line connecting the two open grooves 64, and then the first vertical push rod 152 is used to drive the groove seat 155 to move upward. After the clamping device 15 completes the clamping of the aviation display frame 6, the clamping device 15 can be cyclically displaced with the slider 11. During the displacement process, the aviation display frame 6 is driven to be vertically reciprocated and lifted by the first vertical push rod 152. At the same time, since the axial height value of the first gear ring 154 is much greater than the height value of the convex teeth in the rectangular rack 14, it is ensured that the first gear ring 154 is always engaged with the convex teeth in the long side section of the rectangular rack 14 during the lifting process of the first vertical axis 153 while translating along the length direction of the long side section of the rectangular rack 14, that is, it is realized while lifting and rotating.

[0054] like Figure 8 and Fig. 9 As shown, the present invention also provides an aviation display frame painting production line, comprising a loading component 2, a unloading component 5, a transfer component 4, a functional slot 3 and an aviation display frame hanging conveyor 1. There are three aviation display frame hanging conveyors 1 in total and they are arranged side by side. A transfer component 4 for realizing the transfer of the aviation display frame 6 is installed between two adjacent aviation display frame hanging conveyors 1 near the front end. Functional slots 3 are arranged below the three aviation display frame hanging conveyors 1. The three functional slots 3 serve as cleaning and degreasing slots, primer coating slots and topcoat coating slots in turn. The loading component 2 is installed on the front side of the cleaning and degreasing slot, and the unloading component 5 is installed on the front side of the topcoat coating slot. The structures of the loading component 2 and the unloading component 5 are the same.

[0055] like Fig.10 and Fig.11As shown, the loading assembly 2 includes a rectangular box 21, and the upper and lower ends of the rectangular box 21 are open. Two groups of vertical conveyor belts 22 are symmetrically arranged on both sides of the inner cavity of the rectangular box 21, and convex partitions are evenly distributed on the outer side of the belt body of the vertical conveyor belt 22, and the distance between two adjacent convex partitions is greater than the thickness value of the aviation display frame 6. The vertical conveyor belts 22 located on the same side share a driven roller shaft and an active roller shaft, and the outer end of the active roller shaft is installed with a forward and reverse motor 23 for driving it to rotate forward or reverse. Notches are symmetrically opened on both sides of the bottom of the rectangular box 21, and a horizontal conveyor belt 24 is installed through the notch; the spacing value between the two groups of vertical conveyor belts 22 is greater than the bandwidth value of the horizontal conveyor belt 24.

[0056] The working principle of the loading component 2 is: use the vertical conveyor belt 22 to transfer the aviation display frame 6 to be painted to the interior of the rectangular box 21, and the two ends of the aviation display frame 6 protruding relative to the vertical conveyor belt 22 are used as lifting ends, and two sets of vertical conveyor belts 22 are used to jointly lift the aviation display frame 6 to the top to complete the loading work.

[0057] Similarly, the working principle of the unloading component 5 is: using two sets of vertical conveyor belts 22 to jointly move the painted aviation display frame 6 to the bottom end, using the vertical conveyor belts 22 to receive the painted aviation display frame 6, and transfer it from the inside of the rectangular box 21 to the outside, and then using the loading and unloading auxiliary manipulator to transfer it to the assembly area.

[0058] In order to further ensure the accuracy of loading of the loading component 2 and unloading of the unloading component 5, a straightening function is added to the loading and unloading auxiliary manipulators located at the loading and unloading components 2 and 5. The straightening function specifically means that the loading and unloading auxiliary manipulator can straighten the upper groove seat 155 of the clamping device transferred to the top of the loading component 2 / unloading component 5, so that the length direction of the groove seat 155 is parallel to the direction of the connection line of the two open grooves 64 in the aviation display frame 6 to be painted.

[0059] like Fig.12 and Fig.14As shown, the transfer assembly 4 includes a base plate 41, a flip motor 42, a rotating plate 43, a support plate 44, a movable plate 45, a positioning protrusion 46 and a second lifting and flipping mechanism 47. The flip motor 42 is fixed on the upper side of the base plate 41, and the output end of the flip motor 42 is installed with a rotating plate 43. The lower side of the rotating plate 43 is symmetrically fixed with a support plate 44 near both ends, and the support plate 44 is installed with a second lifting and flipping mechanism 47 for driving the movable plate 45 to flip and lift. The upper side of the movable plate 45 is installed with a positioning protrusion 46 that can be inserted into the key slot 63; the upper side of the rotating plate 43 is installed with a camera probe 48 near the center, and the inner side of the web portion of the slot seat 155 is provided with a mark. The camera probe 48 determines the horizontal flip angle of the slot seat 155 by identifying the captured image of the mark, and then controls the second lifting and flipping mechanism 47 to adjust the flip angle of the movable plate 45 accordingly.

[0060] like Fig.13 As shown, the second lifting and flipping mechanism 47 includes a third vertical push rod 471, a third smooth ring, a third vertical shaft 472, a second rotating motor 474, a driving pulley 475, a driven pulley 476 and a transmission belt 477. The third vertical push rod 471 is installed on the supporting plate 44. The movable end of the third vertical push rod 471 is connected to the bottom end of the third vertical shaft 472 through the third smooth ring. The top of the third vertical shaft 472 is fixedly connected to the center of the movable plate 45. A keyway 473 is provided on the outer side of the third vertical shaft 472. A driving pulley 475 is installed at the output end of the second rotating motor 474. A transmission belt 477 is sleeved between the driving pulley 475 and the driven pulley 476. The driven pulley 476 is provided with a movable support by the rotating plate 43. A sliding groove is provided in the driven pulley 476 for the third vertical shaft 472 to pass through. The inner wall of the sliding groove is provided with a convex key that cooperates with the keyway 473.

[0061] The working principle of the second lifting and flipping mechanism 47 is as follows: the third vertical push rod 471 is used to drive the third vertical shaft 472 and the movable plate 45 to perform vertical displacement, the axial height value of the key slot 473 is greater than the height value of the convex key in the driven pulley 476, and when the second rotating motor 474 drives the driving pulley 475 to rotate, the driven pulley 476 can rotate accordingly, so that the third vertical shaft 472 and the movable plate 45 also rotate accordingly.

[0062] The overall working principle of the transfer assembly 4 is as follows: the two movable plates 45 in the transfer assembly 4 are used as material receiving plates. When the clamping device 15 of the current process moves to the top of one movable plate 45, the camera probe 48 is used to identify the image of the alignment mark to determine the horizontal flip angle of the slot seat 155, and then the second lifting and flipping mechanism 47 is controlled to adjust the flip angle of the movable plate 45 accordingly. Then the second lifting and flipping mechanism 47 drives the movable plate 45 to move up and makes the positioning protrusion 46 snap into the key slot 63 corresponding to the aviation display frame 6. Then the clamping device 15 releases the clamping and locking of the aviation display frame 6, and the transfer assembly 4 flips the positions of the two movable plates 45 so that the aviation display frame 6 is located below the clamping device 15 of the subsequent process. The camera probe 48 is used to identify the image of the alignment mark to determine the horizontal flip angle of the slot seat 155, and then the second lifting and flipping mechanism 47 is controlled to adjust the flip angle of the movable plate 45 accordingly. The clamping device 15 of the subsequent process is used to clamp and lock the aviation display frame 6, and the transfer operation is realized in this way.

[0063] like Fig.15 As shown, the functional tank 3 includes a liquid storage tank portion 31 for cleaning or immersion and a liquid receiving tank portion 32 for receiving liquid. The liquid storage tank portion 31 and the liquid receiving tank portion 32 are arranged side by side, and a liquid inlet pipe and a liquid outlet pipe with an opening valve are installed at the side end of the liquid storage tank portion 31. The bottom surface of the liquid receiving tank portion 32 is an inclined surface, and the lower end of the inclined surface is arranged close to the liquid storage tank portion 31.

[0064] In this embodiment, a hot air blower is provided above the liquid receiving tank 32 for facilitating draining or drying.

[0065] The specific application of this embodiment is: the loading component 2 transfers the aviation display frame 6 to be painted to the loading station, and the aviation display frame hanging conveyor 1 located above the cleaning and degreasing tank uses the clamping device 15 to reliably clamp the aviation display frame 6, and drive it to translate in the liquid storage tank part 31 of the cleaning and degreasing tank. During the translation process, it is lifted and rotated at the same time to ensure the cleaning and degreasing effect, and then the aviation display frame 6 is transferred to the liquid receiving tank part 32 of the cleaning and degreasing tank by using the clamping device 15 for draining, which can be cooperated with the hot air blower above to achieve rapid draining. Then, the first transfer component 4 is used to transfer the cleaned and degreased aviation display frame 6 to the front side of the primer coating tank, and the aviation display frame 6 is securely clamped by the clamping device 15 of the aviation display frame hanging conveyor 1 above the primer coating tank, and is driven to translate in the liquid storage tank part 31 of the primer coating tank. During the translation, it is lifted and rotated at the same time to ensure the effect of primer coating, and then the aviation display frame 6 is transferred to the liquid receiving tank part 32 of the primer coating tank by the clamping device 15 for draining, which can be quickly dried in conjunction with the hot air blower above. The cleaned and degreased aviation display frame 6 is then transferred to the front side of the topcoat painting tank by the second transfer assembly 4. The aviation display frame 6 is reliably clamped by the clamping device 15 of the aviation display frame hanging conveyor 1 above the topcoat painting tank, and is driven to translate in the liquid storage tank 31 of the topcoat painting tank. During the translation, it is lifted and rotated at the same time to ensure the effect of topcoat painting. Then, the aviation display frame 6 is transferred to the liquid receiving tank 32 of the topcoat painting tank by the clamping device 15 for draining, and can be quickly dried in conjunction with the hot air blower above. The painted aviation display frame 6 is transferred from the unloading station to the outside by the unloading assembly 5, and then transferred to the assembly area by the loading and unloading auxiliary manipulator.
