Description

Technical Field

[0001] The invention relates to the technical field of automobile component production, in particular to a production and transportation line for automobile exterior panels with multi-layered color textures and a working method thereof. Background Art

[0002] Automobile exterior panels are the main structural components of automobiles. Automobile exterior panels of different specifications have different curvatures. When transporting them, there is a lack of corresponding supporting handling equipment for docking. Most of them are manually transported, which has poor stability and safety. They are often painted after production, and the color 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 standard of their surface color and texture. At this time, the staff will use a colorimeter for testing, usually hand-held by the staff, and then stick it on the exterior panel for testing, which is time-consuming and labor-intensive.

[0003] An existing patent application with publication number CN 110963302A discloses a curved cover glass adsorption jig, comprising a main shell, a base is fixedly arranged at the bottom end of the inner cavity of the main shell, an air suction pump is fixedly arranged at the top end of the base, an air extraction chamber is arranged at the top end of the air suction pump, a bracket bottom plate is fixedly arranged at the top end of the air extraction chamber, a lifting bracket is fixedly arranged at the top end of the bracket bottom plate, an elastic bottom plate is fixedly arranged at the top end of the lifting bracket, a suction cup is arranged at the top end of the elastic bottom plate, the bottom end of the suction cup passes through the elastic bottom plate, an air guide tube is arranged at the bottom end of the suction cup, the bottom end of the air guide tube passes through the bracket bottom plate, sliding bases are fixedly arranged at the top ends of the left and right sides of the main shell, a baffle is arranged at the top end of the sliding base, and bolts are arranged on the front surface of the sliding base.

[0004] In the above technical scheme, the elastic base plate can be deformed by the extension and retraction of the lifting bracket, and deformed accordingly for different curved surfaces. According to the curvature of the curved cover glass to be adsorbed, the direction of the elastic base plate is changed by adjusting the height of the lifting bracket, and then the direction of the suction cup is changed, so that the curved cover glass can be better adsorbed. However, this scheme can only change the direction of the suction cup by driving the elastic base plate simultaneously by several lifting brackets. When the driving force of the lifting bracket is cancelled, it is reset to a horizontal state under the resetting action of the elastic base plate, and the direction of the suction cup is also reset to the initial position at the same time, and it cannot be attached to the curved glass for adsorption, and the stability is poor. Moreover, the elastic base plate itself has a certain area, and even under the drive of several lifting brackets, it cannot adjust to any curvature, and forced adjustment may also cause self-damage.

[0042] See also Figure 1-10 The present invention provides a technical solution: a production and transportation line for multi-layer color texture automobile exterior panels and a working method thereof, comprising a base 8, a handling component 1, a transport roller 1 5, a transport roller 2 501 and a detection component,

[0043] The transport roller 1 5 and the transport roller 2 501 have the same structure and are symmetrically arranged at both ends of the detection assembly. The transport roller 1 5 includes a transport base 4. A plurality of intermediate rollers 401 are arranged on the middle side of the transport base 4. Auxiliary inclined rollers 402 are symmetrically arranged on both sides of the intermediate rollers 401. The transport roller 1 5 and the transport roller 2 501 are used to transport the exterior decorative panel body 6.

[0044] The transport assembly 1 is arranged on the upper side of the detection assembly, and is used to transport the exterior panel body 6 to be detected on the transport roller 1 5 to the upper side of the detection assembly for detection, and then transport the exterior panel body 6 after the detection to the transport roller 2 501;

[0045] The transport component 1 includes a plurality of suction cups 101, the upper end of the suction cup 101 is fixedly connected to a ventilation column 102, an air cavity is provided on the inner side of the ventilation column 102, the air cavity extends to the outer side of the ventilation column 102 and is connected to an air pump hose, the upper end spherical hinge of the ventilation column 102 is connected to a hinge ball 103, and the upper end spherical hinge of the hinge ball 103 is connected to a connecting column 104.

[0046] First, the exterior panel body 6 to be inspected is driven to be transported along the transport roller 5 through the rotation of the middle roller 401 and the support of the auxiliary inclined rollers 402 on both sides. The exterior panel body 6 moves to the lower side of the handling assembly 1, and the suction cup 101 is driven to descend and contact the surface of the exterior panel body 6 through a number of connecting columns 104. The spherical hinge connection of the hinge ball 103 allows the ventilation column 102 and the suction cup 101 to rotate and adjust with the hinge ball 103 as the rotation center point to adapt to the surface curvature of the exterior panel body 6, so that the suction cup 101 is completely attached to the exterior panel body 6 for adsorption, thereby improving the stability of adsorption, and can be adjusted for exterior panel bodies 6 with various curvatures, with strong versatility; then the transport component 1 drives the adsorbed exterior panel body 6 to move to the upper side of the detection component, and the detection component performs surface color detection on it; then the transport component 1 transports the inspected exterior panel body 6 to the transport roller 2 501, and resets to start the next round of detection work, thereby realizing continuous and automatic detection of the exterior panel body 6 and improving work efficiency.

[0047] The upper end of the ventilation column 102 is fixedly connected to a support plate 105, and the upper end of the support plate 105 is fixedly connected to a plurality of hinge seats 106. The upper end of the hinge seat 106 is spherically hinged to a hinge ball 107, and the upper end of the hinge ball 107 is fixedly connected to a support rod 108. The upper end of the support rod 108 is hinged to a sliding block 109. A plurality of vertical grooves 110 are provided on the outer side of the connecting column 104, and the sliding block 109 slides in the vertical grooves 110. A locking structure is provided on the inner side of the sliding block 109, and the locking structure is used to fix the sliding block 109 in the vertical groove 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 transport assembly 1 also includes a supporting cavity 3, which is fixed to the upper side of the base 8. The upper end of the top cover 115 is fixedly connected to the lifting plate 2. The upper end of the lifting plate 2 is provided with a plurality of electric telescopic rods 201. The upper end of the electric telescopic rods 201 is provided with a moving seat 202. Both ends of the moving seat 202 are penetrated and slidably matched with guide rods. The middle side of the moving seat 202 is penetrated and threadedly connected with a threaded rod 203. Both ends of the guide rod are fixed to the inner side of the supporting cavity 3, and both ends of the threaded rod 203 are rotatably connected to the inner side of the supporting cavity 3.

[0056] Preferably, the lifting plate 2 is driven to rise and fall by the electric telescopic rod 201, which can drive the top cover 115 to rise and fall, thereby adsorbing and lifting the exterior panel body 6, and then the threaded rod 203 is driven to rotate by the motor assembly to drive the moving seat 202, thereby driving the exterior panel body 6 to move for transportation.

[0057] The detection component includes a colorimeter 301 and a detection cavity 302. The detection cavity 302 is connected to the transport 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 move in the X-axis and Y-axis directions.

[0058] Preferably, in order to improve the comprehensiveness and accuracy of the detection, the colorimeter 301 is driven by a horizontal moving mechanism to move in all directions, so as to perform a comprehensive detection on every part of the exterior trim body 6 .

[0059] An electric telescopic column is provided at the lower end of the colorimeter 301, and a movable translation seat 303 is provided at the lower end of the electric telescopic column. The lower end of the translation seat 303 is slidably matched with a movable displacement table 304. The displacement table 304 slides along the inner side of the detection cavity 302. A pair of guide rods 305 are provided on the inner side of the detection cavity 302. The guide rods 305 pass through the displacement table 304 and slidably match therewith.

[0060] Preferably, since the exterior panel body 6 is a curved surface, in order to avoid inaccurate detection results due to different distances 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 adjust along with the curvature of the exterior panel body 6, thereby ensuring the accuracy of the detection data. Then, the colorimeter 301 is driven to move in the X-axis and Y-axis directions through the translation seat 303 and the displacement platform 304 to ensure comprehensive detection.

[0061] The horizontal moving mechanism includes a threaded long rod 204, which passes through the displacement platform 304. A pair of transmission chains 205 are arranged on the inner side of the displacement platform 304. The upper end of the transmission chain 205 is fixedly connected to the translation seat 303. The middle side of the transmission chain 205 is meshedly connected with a driving sprocket 206. Both ends of the transmission chain 205 are provided with driven sprockets 207. The guide rod 305 passes through the driven sprocket 207 and is clearance-matched with the driven sprocket 207. The threaded long rod 204 passes through the driving sprocket 206 and is clearance-matched with the driven sprocket 207.

[0062] Preferably, when it is necessary to drive the translation platform 304 to move, the threaded long rod 204 is driven to rotate through the motor assembly, and the translation platform 304 is driven to move through the threaded connection. When it is necessary to drive the translation seat 303 to move, the driving sprocket 206 and the transmission chain 205 are meshed with each other, thereby driving the transmission chain 205 to move, thereby driving the translation seat 303 to move, and because the guide rod 305 and the driven sprocket 207 are clearance-matched, the threaded long rod 204 passes through the driving sprocket 206 and is clearance-matched therewith, so that both the driving sprocket 206 and the driven sprocket 207 can be displaced along the direction of the guide rod 305, and the normal displacement of the translation platform 304 will not be affected.

[0063] The inner side of the displacement platform 304 is rotatably connected with an internal threaded sleeve 208, the threaded long rod 204 penetrates the internal threaded sleeve 208 and is threadedly connected thereto, both ends of the internal threaded sleeve 208 are fixedly connected to the driving sprocket 206, an electromagnet block is arranged on the inner side of the displacement platform 304, and the internal threaded sleeve 208 is arranged as a magnetic metal.

[0064] Preferably, an electromagnet block and an internal threaded sleeve 208 are provided. When it is necessary to control the displacement of the translation platform 304, the electromagnet block is energized, so that the translation platform 304, the internal threaded sleeve 208 and the driving sprocket 206 are all fixed as a whole, and the threaded long rod 204 rotates relative to the internal threaded sleeve 208, thereby driving the translation platform 304 to move to a corresponding position. Then, when it is necessary to drive the translation seat 303, the electromagnet block is de-energized, so that the internal threaded sleeve 208 and the driving sprocket 206 can rotate relative to the translation platform 304. At this time, the threaded long rod 204 rotates, and the friction force between the threaded connections directly drives the internal threaded sleeve 208 to rotate, thereby driving the driving sprocket 206 to rotate, and the transmission chain 205 can be driven to drive the translation seat 303 to move. In other words, the on and off of the electromagnet block can enable a single threaded long rod 204 to achieve the displacement drive of the translation platform 304 and the displacement drive of the translation seat 303, which saves costs and has a high degree of automation.
