Description

Technical Field

[0001] The present invention relates to the technical field of automotive component production, and particularly to a production and transportation line for automotive exterior panels with multi-level color textures and its working method. Background Art

[0002] Automotive exterior panels are the main structural components of automobiles. Different specifications of automotive exterior panels have different curvatures. When transporting them, there is a lack of corresponding supporting handling equipment for docking. Most of them are manually transported, with poor stability and safety. And after production, they are often colored, and the chromaticity of the exterior panels needs to be controlled within the qualified standard range. Especially for exterior panels with multi-level color textures, it is more necessary to ensure the standards of their surface chromaticity and texture. At this time, workers will use a colorimeter for detection. Usually, the worker holds it by hand and then fits it on the exterior panel for detection, which is time-consuming and laborious.

[0003] In the prior patent application publication number CN 110963302A, a curved surface cover glass adsorption jig is disclosed, including a main body shell. At the bottom end of the inner cavity of the main body shell, a base is fixedly arranged. At the top end of the base, an air suction pump is fixedly arranged. At the top end of the air suction pump, an air extraction cavity is arranged. At the top end of the air extraction cavity, a support base plate is fixedly arranged. At the top end of the support base plate, a lifting support is fixedly arranged. At the top end of the lifting support, an elastic base plate is fixedly arranged. At the top end of the elastic base plate, a suction cup is arranged. The bottom end of the suction cup penetrates through the elastic base plate. At the bottom end of the suction cup, an air guide pipe is arranged. The bottom end of the air guide pipe penetrates through the support base plate. At the top ends of the left and right sides of the main body shell, sliding bases are fixedly arranged. At the top end of the sliding base, a baffle is arranged. On the front surface of the sliding base, a bolt is arranged.

[0004] In the above technical solution, the elastic base plate can be deformed by the telescopic movement of the lifting support, and corresponding deformations can be made for different curved surfaces. According to the curvature of the adsorbed curved surface cover glass, by adjusting the height of the lifting support, the direction of the elastic base plate can be changed, and then the direction of the suction cup can be changed, so as to better adsorb the curved surface cover glass. However, in this scheme, only when several lifting supports drive the elastic base plate simultaneously can the direction of the suction cup be changed. When the driving force of the lifting support is cancelled, under the reset action of the elastic base plate, it resets to a horizontal state, and at the same time, the direction of the suction cup also resets to the initial position, and it cannot fit on the curved surface glass for adsorption, with poor stability. And the elastic base plate itself has a certain area. Even under the drive of several lifting supports, it cannot be adjusted for any curvature, and forced adjustment may cause its own damage.

[0005] Therefore, it is necessary to provide a production and transportation line for automotive exterior panels with multi-level color textures and its working method, which can achieve the functions of general transportation and detection. Summary of the Invention

[0041] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0042] Please refer to Figures 1-10 , the present invention provides a technical solution: a production and transportation line for a multi-level color and texture automotive exterior trim panel and its working method, including a base 8, a handling component 1, a transportation roller path one 5, a transportation roller path two 501, and a detection component,

[0043] The first conveying roller path 5 and the second conveying roller path 501 have the same structure and are symmetrically arranged at both ends of the detection component. The first conveying roller path 5 includes a conveying base 4. A number of intermediate rollers 401 are arranged in the middle of the conveying base 4. Auxiliary inclined rollers 402 are symmetrically arranged on both sides of the intermediate rollers 401. The first conveying roller path 5 and the second conveying roller path 501 are used to convey the exterior trim panel body 6.

[0044] The handling component 1 is arranged above the detection component. The handling component 1 is used to carry the exterior trim panel body 6 to be detected on the first conveying roller path 5 above the detection component for detection, and then carry the detected exterior trim panel body 6 to the second conveying roller path 501.

[0045] The handling component 1 includes a number of suction cups 101. The upper end of the suction cup 101 is fixedly connected with an air vent column 102. An air cavity is arranged inside the air vent column 102. The air cavity extends to the outside of the air vent column 102 and is connected with an air pump hose. The upper end of the air vent column 102 is spherically hinged with a hinge ball 103. The upper end of the hinge ball 103 is spherically hinged with a connecting column 104.

[0046] First, through the rotation of the intermediate rollers 401 and the support of the auxiliary inclined rollers 402 on both sides, the exterior trim panel body 6 to be detected is driven to be conveyed along the first conveying roller path 5. When the exterior trim panel body 6 moves to the lower side of the handling component 1, the suction cups 101 are driven by a number of connecting columns 104 to descend and contact the surface of the exterior trim panel body 6. Through the spherical hinge connection of the hinge ball 103, the air vent column 102 and the suction cups 101 rotate and adjust with the hinge ball 103 as the rotation center point to adapt to the surface curvature of the exterior trim panel body 6, so that the suction cups 101 are completely attached to the exterior trim panel body 6 for adsorption, thereby improving the adsorption stability and can be adjusted for a variety of exterior trim panel bodies 6 with different curvatures, with strong versatility. Then, the handling component 1 drives the adsorbed exterior trim panel body 6 to move above the detection component, and the detection component performs surface chromaticity detection on it. Then, the handling component 1 carries the detected exterior trim panel body 6 to the second conveying roller path 501 and resets to start the next round of detection work, thereby realizing the continuous automatic detection of the exterior trim panel body 6 and improving work efficiency.

[0047] The upper end of the air vent column 102 is fixedly connected with a support disk 105. The upper end of the support disk 105 is fixedly connected with a number of hinge seats 106. The upper end of the hinge seat 106 is spherically hinged with a hinge ball 107. The upper end of the hinge ball 107 is fixedly connected with a support rod 108. The upper end of the support rod 108 is hinged with a sliding block 109. A number of vertical grooves 110 are arranged on the outside of the connecting column 104. The sliding block 109 slides in the vertical grooves 110. A locking structure is arranged inside the sliding block 109. The locking structure is used to fix the sliding block 109 in the vertical grooves 110.

[0048] Preferably, since the exterior panel body 6 has a certain weight, and the suction cup 101 is only adsorbed on the curved surface after the angle of the hinge ball 103 is adjusted, when the exterior panel body 6 needs to be lifted, the larger weight will pull the suction cup 101 downward, and the pulling force perpendicular to the ground will reset the angle of the suction cup 101, so that the suction cup 101 cannot be fully attached to the curved surface, and may even leak, causing the exterior panel body 6 to fall, with poor stability. Therefore, a locking structure is provided. Specifically, a support plate 105 is first provided at the upper end of the ventilation column 102, and the support plate 105 can rotate accordingly with the ventilation column 102 and the suction cup 101 to adjust the angle. When the angle of the support plate 105 changes, a plurality of support rods 101 are driven accordingly. 8 position changes, the hinge ball 107 adapts, and the upper end of the support rod 108 is provided with a sliding block 109, the sliding block 109 is restricted to slide in the vertical groove 110, when the angle of the support plate 105 changes, a number of sliding blocks 109 correspondingly slide in the vertical groove 110 to adapt. Therefore, when the suction cup 101 adjusts the corresponding angle and adsorbs on the exterior panel body 6, the sliding block 109 also stops sliding at this time, and then the sliding block 109 is fixed in the vertical groove 110 through the locking structure, thereby locking the current position of the sliding block 109, and the position of the support rod 108 and the support plate 105 can be fixed, so as to further stabilize the angular position of the suction cup 101, thereby improving the stability of adsorbing the exterior panel body 6.

[0049] The locking structure includes a limiting rod 111 , which penetrates through the sliding block 109 and slidably cooperates therewith. A plurality of limiting holes 112 are vertically opened on the inner side of the vertical slot 110 .

[0050] Preferably, when the position of the sliding block 109 needs to be fixed, a plurality of limiting holes 112 are provided in the vertical slot 110 , and the limiting rod 111 is inserted into the limiting hole 112 , thereby fixing the sliding block 109 at the current height position.

[0051] The outer side of the limit rod 111 is fixedly connected with an arc plate 113, and both ends of the arc plate 113 are provided with chamfers. A contraction spring member is provided between the arc plate 113 and the sliding block 109, and the contraction spring member is sleeved on the outer side of the limit rod 111;

[0052] A spring telescopic rod 114 is provided at the upper end of the connecting column 104, and a top cover 115 is provided at the upper end of the spring telescopic rod 114. A plurality of plug plates 116 are fixedly connected to the lower end of the top cover 115. The plug plates 116 are staggered with the support rod 108, and an oblique chamfer is provided at the lower end of the plug plates 116. The plug plates 116 are adapted to the arc plate 113, and the plug plates 116 are slidably matched with the outer side of the connecting column 104.

[0053] Preferably, when it is necessary to drive the limit rod 111 to move and thus jam the sliding block 109, an arc plate 113 is provided on the outer side of the limit rod 111. Specifically, under the action of the contraction spring member, the arc plate 113 is initially fitted to the outer side of the connecting column 104, and the limit rod 111 is also inserted into the limit hole 112, that is, the position of the suction cup 101 is fixed downward at this time, and then the top cover 115 is lowered to make the connecting column 104 lower, and the suction cup 101 contacts the outer decorative plate body 6. At this time, the suction cup 101 cannot continue to descend, nor can it adjust the angle to fit the curved surface. The top cover 115 continues to descend, and the spring telescopic rod 114 is compressed. The top cover 115 pushes the plurality of plug plates 116 to descend relative to the connecting column 104 until the plug plates 116 contact the chamfered corners of the arc plate 113, pushing the arc plate 113 outward, so that the limiting rod 111 is away from the limiting hole 112, so that the suction cup 101 can be adjusted in angle, and as the top cover 115 contacts the upper end of the connecting column 104, the connecting column 104 is pressed downward, so that the suction cup 101 is subjected to pressure, and after adjusting the corresponding angle, it is fully fitted on the curved surface, and then the suction cup 101 can be driven to suck Attached to the exterior panel body 6, after the adsorption is completed, the top cover 115 drives the plug plate 116 to rise and reset, while the suction cup 101 and the connecting column 104 remain at a fixed height until the plug plate 116 is separated from the arc plate 113. Under the resetting action of the contraction spring member, the limit rod 111 is re-engaged in the limit hole 112 after the adjusted position, and the positioning of the sliding block 109 is completed, so that the position and angle of the suction cup 101 are fixed, and then the top cover 115 rises until the spring telescopic rod 114 is completely reset, and the top cover 115 can pull the spring telescopic rod 114 to drive the connecting column 104 and the suction cup 101 rises, the outer panel body 6 can be lifted, so as to be transported, that is, the loosening and fixing of the suction cup 101 can be achieved only by the lifting and lowering of the top cover 115, and the top cover 115 descends, driving the suction cup 101 to loosen, and further, driving the suction cup 101 to descend, so as to contact and adsorb with the outer panel body 6, which is highly practical. Conversely, the top cover 115 rises, driving the suction cup 101 to fix its own position, and further, driving the suction cup 101 to rise, so as to lift the outer panel body 6, and then the transport work can be started, which has a high degree of automation and improves work efficiency.

[0054] Preferably, in order to further improve the stability of the top cover 115 pulling the connecting column 104 to rise, a slot is provided on the outer side of the connecting column 104, and a card plate 9 is slidably provided in the slot, and the card plate 9 is fixed on the inner side of the plug plate 116. When the top cover 115 and the plug plate 116 rise, the card plate 9 is pulled up, and the card plate 9 is stuck in the upper end of the slot, thereby driving the connecting column 104 to rise, thereby improving the stability of carrying the exterior panel body 6.

[0055] The handling component 1 further includes a support cavity 3. The support cavity 3 is fixed to the upper side of the base 8. The upper end of the top cover 115 is fixedly connected to a lifting plate 2. A plurality of electric telescopic rods 201 are arranged at the upper end of the lifting plate 2. The upper end of the electric telescopic rod 201 is provided with a moving seat 202. Both ends of the moving seat 202 penetrate and are slidably matched with a guide rod. The middle side of the moving seat 202 penetrates and is threadedly connected to a threaded rod 203. Both ends of the guide rod are fixed to the inner side of the support cavity 3, and both ends of the threaded rod 203 are rotatably connected to the inner side of the support cavity 3.

[0056] Preferably, by driving the lifting plate 2 to lift and lower through the electric telescopic rod 201, the top cover 115 can be driven to lift and lower, so as to adsorb and lift the exterior panel body 6. Then, by driving the threaded rod 203 to rotate through the motor assembly and driving the moving seat 202, the exterior panel body 6 can be driven to move for handling.

[0057] The detection component includes a colorimeter 301 and a detection cavity 302. The detection cavity 302 is connected to the two transportation bases 4 on both sides. A horizontal moving mechanism is arranged inside the detection cavity 302. The horizontal moving mechanism drives the colorimeter 301 to perform displacements in the X-axis and Y-axis directions.

[0058] Preferably, in order to improve the comprehensiveness and accuracy of detection, the colorimeter 301 is driven by the horizontal moving mechanism to perform full-direction displacement to comprehensively detect each part of the exterior panel body 6.

[0059] An electric telescopic column is arranged at the lower end of the colorimeter 301. A movable translation seat 303 is arranged at the lower end of the electric telescopic column. A movable displacement table 304 is slidably matched with the lower end of the translation seat 303. The displacement table 304 slides along the inner side of the detection cavity 302. A pair of guide rods 305 are arranged inside the detection cavity 302. The guide rods 305 penetrate through the displacement table 304 and are slidably matched with it.

[0060] Preferably, since the exterior panel body 6 is a curved surface, in order to avoid inaccurate detection results caused by the inconsistent distance between the colorimeter 301 and the surface of the exterior panel body 6 during detection, an electric telescopic column is provided. The height position of the colorimeter 301 is controlled by the electric telescopic column to be adjusted according to the curvature of the exterior panel body 6, so as to ensure the accuracy of the detection data. Then, through the translation seat 303 and the displacement table 304, the colorimeter 301 is driven to perform displacements in the X-axis and Y-axis directions to ensure comprehensive detection.

[0061] The horizontal movement mechanism includes a threaded long rod 204 which penetrates through the displacement table 304. A pair of drive chains 205 are arranged inside the displacement table 304. The upper ends of the drive chains 205 are fixedly connected to the translation base 303. A driving sprocket 206 is meshed and connected to the middle side of the drive chain 205. Driven sprockets 207 are arranged at both ends of the drive chain 205. A guide rod 305 penetrates through the driven sprockets 207 and has a clearance fit with them. The threaded long rod 204 penetrates through the driving sprocket 206 and has a clearance fit with it.

[0062] Preferably, when it is necessary to drive the displacement table 304 to move, the threaded long rod 204 is driven to rotate by the motor assembly, and the displacement table 304 is driven to displace through threaded connection. When it is necessary to drive the translation base 303 to displace, the driving sprocket 206 and the drive chain 205 are meshed with each other, so as to drive the drive chain 205 to move and drive the translation base 303 to displace. And because the guide rod 305 has a clearance fit with the driven sprockets 207, and the threaded long rod 204 penetrates through the driving sprocket 206 and has a clearance fit with it, the driving sprocket 206 and the driven sprockets 207 can both displace along the direction of the guide rod 305, without affecting the normal displacement of the displacement table 304.

[0063] An internally threaded sleeve 208 is rotatably connected inside the displacement table 304. The threaded long rod 204 penetrates through the internally threaded sleeve 208 and is threadedly connected to it. Both ends of the internally threaded sleeve 208 are fixedly connected to the driving sprocket 206. An electromagnet block is arranged inside the displacement table 304. The internally threaded sleeve 208 is made of magnetic metal.

[0064] Preferably, the electromagnet block and the internally threaded sleeve 208 are provided. When it is necessary to control the displacement of the displacement table 304, the electromagnet block is electrified at this time, so that the displacement table 304, the internally threaded sleeve 208 and the driving sprocket 206 are all fixed as a whole. The threaded long rod 204 rotates relative to the internally threaded sleeve 208, thereby driving the displacement table 304 to displace to the corresponding position. Then when it is necessary to drive the translation base 303, the electromagnet block is powered off at this time, so that the internally threaded sleeve 208 and the driving sprocket 206 can rotate relative to the displacement table 304. At this time, the threaded long rod 204 rotates, and through the friction force between the threaded connections, the internally threaded sleeve 208 is directly driven to rotate, thereby driving the driving sprocket 206 to rotate, and then the drive chain 205 can be driven to drive the translation base 303 to displace. That is to say, by the power on and off of the electromagnet block, a single threaded long rod 204 can realize the displacement drive of the displacement table 304 and the displacement drive of the translation base 303, saving costs and having a high degree of automation.
