Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive parts spraying, handling, and rotating device. Background Technology

[0002] In the automotive parts manufacturing industry, the production process for sheet materials, such as door inner panels and engine hoods, involves several key stages, including stamping, surface treatment, and painting. After the painting process is completed, these materials need to be transported to different workstations to facilitate subsequent assembly and testing. During this process, situations involving reversible transport are unavoidable.

[0003] Currently, the industry commonly uses transfer conveyors or transfer loaders to achieve the turning and conveying of sheet materials. Transfer conveyors are typically track-mounted automated devices that, driven by motors and complex transmission mechanisms, enable the lateral or longitudinal movement of materials on a pre-set track, and complete the turning action through a specific turning mechanism. Transfer loaders, on the other hand, often utilize a combination of robotic arms, conveyor belts, and other structures, employing precise control algorithms to transfer materials from one conveyor line to another in a different direction, achieving turning and conveying. These complex structures not only increase the difficulty of equipment design and manufacturing but also directly lead to higher procurement costs, hindering widespread application.

[0032] Please refer to Figure 1 and Figure 2 This utility model provides an automotive parts spraying and handling rotary device 100, which is applied to an automotive parts production line and includes:

[0033] The support frame 200 has a rectangular frame structure. The upper crossbeam of the support frame 200 includes a first upper crossbeam 210 and a second upper crossbeam 220 arranged opposite to each other. Two connecting rods 230 are spaced apart between the two first upper crossbeams 210.

[0034] The feeding conveying mechanism 300 includes two feeding roller sets 310 respectively mounted on two connecting rods 230, and a feeding conveying belt 320 sleeved on the feeding roller sets 310.

[0035] The discharge conveying mechanism is set perpendicularly to the feed conveying mechanism 300. The discharge conveying mechanism includes two discharge roller sets and a discharge conveying belt 420 sleeved on the discharge roller sets. The two discharge roller sets are respectively set on the two first upper crossbeams 210.

[0036] The steering mechanism 500 is located between the two connecting rods 230. The steering mechanism 500 includes a rotary table 510 and a rotary drive 520 connected to the rotary table 510. The rotary table 510 is used to carry the carrier and can rotate relative to the feeding conveyor mechanism 300.

[0037] The main function of the support frame 200 is to provide support for the overall mechanism. Its material can be stainless steel or aluminum alloy, etc. For example, the support frame 200 is made of stainless steel, which has strong corrosion resistance and can maintain a long service life in a factory environment; it also has high strength, giving the support frame 200 good resistance to compression, tension, and bending, thus improving the stability of the mechanism. Of course, the above is only an example, and the specific material can be determined according to actual needs; this utility model does not impose any limitations.

[0038] The support frame 200 has a rectangular structure and is composed of columns and beams. The upper crossbeam includes a first upper crossbeam 210 and a second upper crossbeam 220 arranged opposite each other, and the first upper crossbeam 210 and the second upper crossbeam 220 are connected in sequence to form a rectangle.

[0039] Two connecting rods 230 are arranged between the two first upper crossbeams 210, and the feeding conveying mechanism 300 is mounted on the connecting rods 230. Specifically, the feeding conveying mechanism 300 includes two sets of feeding rollers 310 respectively mounted on the two connecting rods 230, and a feeding conveyor belt 320 sleeved on the feeding rollers 310. The rotation of the feeding rollers 310 drives the feeding conveyor belt 320 to move. When the carrier contacts the feeding conveyor belt 320, the plate-shaped material is conveyed by the feeding conveyor belt 320 to the preset position of the mechanism, waiting for turning.

[0040] The main function of the discharge conveyor is to transport the carrier and plate-shaped materials off the production line. The discharge conveyor is perpendicular to the feed conveyor 300. Specifically, the discharge conveyor includes two sets of discharge rollers respectively mounted on the two first upper crossbeams 210, and a discharge conveyor belt 420 fitted onto the discharge rollers. After the carrier turns, when it contacts the discharge conveyor belt 420, the plate-shaped material is conveyed off the production line by the discharge conveyor belt 420. The feed conveyor 300 is perpendicular to the discharge conveyor, utilizing a rectangular frame structure to achieve material turning and transmission within a limited space, reducing the production line footprint. This is suitable for compact layouts with multiple processes in automotive parts production, improving space utilization.

[0041] The main function of the steering mechanism 500 is to rotate the carrier and plate-shaped material, adjusting their direction for directional conveying. It is positioned between two connecting rods 230 and can be integrated with the feeding and discharging mechanisms using the rectangular frame structure of the support frame 200, enhancing the compact design of the mechanism. The steering mechanism 500 includes a rotating platform 510 for supporting the carrier and a rotary drive 520. When the carrier is conveyed by the feeding and discharging mechanism 300 to the position of the rotating platform 510, the rotary drive 520 drives the rotating platform 510 to rotate 90°, aligning the carrier's forward direction with the discharging mechanism, enabling directional conveying. The rotary drive 520 can be a motor or a gear transmission structure, as long as it enables the rotating platform 510 to rotate; this invention does not impose any limitations.

[0042] When plate-shaped materials are placed on a carrier, they are carried by the carrier from the previous process to the rotary conveyor mechanism. The carrier contacts the feed conveyor belt 320 of the feed conveyor mechanism 300 and is conveyed to the rotary table 510 of the steering mechanism 500. The rotary drive 520 drives the rotary table 510 to rotate 90°. At this time, the forward direction of the carrier is aligned with the discharge conveyor mechanism, and the carrier contacts the discharge conveyor belt 420 of the discharge conveyor mechanism and is conveyed for unloading.

[0043] This utility model features a support frame 200 with a frame structure. Two first upper crossbeams 210 on the support frame 200 are connected to two connecting rods 230. Each connecting rod 230 is equipped with a feeding roller assembly 310 and a feeding conveyor belt 320. A discharge conveying mechanism is perpendicular to the feeding conveying mechanism 300. The discharge roller assembly and discharge conveyor belt 320 are correspondingly mounted on the first upper crossbeams 210. The rotating platform 510 and rotating drive component 520 of the steering mechanism 500 are positioned between the two connecting rods 230. The carrier carries the material to the feeding conveying mechanism 300. 00, the feeding roller assembly 310 rotates, driving the feeding conveyor belt 320 to rotate, thereby moving the carrier to the rotary table 510 of the steering mechanism 500. The rotary drive 520 drives the rotary table 510 to rotate 90°. At this time, the forward direction of the carrier is aligned with the discharge conveyor mechanism, and the carrier contacts the discharge conveyor belt 420 of the discharge conveyor mechanism and is conveyed and discharged, improving the material conveying efficiency of the production line. In addition, the rotary conveyor mechanism makes full use of the idle space of the frame structure, improves the compactness of the mechanism, and has a simple structure, which is easy to implement at low cost.

[0044] Please refer to Figure 2 and Figure 4 The steering mechanism 500 also includes a lifting platform 530 located below the rotary table 510. The lifting platform 530 is connected to a lifting drive component 540, and a rotating component 550 is provided between the rotary table 510 and the lifting platform 530.

[0045] In some embodiments, the lifting drive 540 can be a cylinder, a hydraulic cylinder, or an electric push rod, etc., which drives the lifting platform 530 to move up and down through linear motion. As long as the lifting platform 530 can move up and down, it is acceptable. The specific type can be determined according to actual needs, and this utility model does not impose any restrictions here.

[0046] The rotary table 510 and the lifting table 530 are connected by a rotating component 550. A rotating drive component 520 is connected to the rotating component 550, which drives the rotating component 550 to rotate. The rotating component 550 drives the rotary table 510 to rotate, thereby adjusting the orientation of the carrier and the material. For example, the rotating component 550 is a rotary bearing.

[0047] The carrier is conveyed by the feed conveyor belt 320 to a position directly above the rotary table 510, where it rests on the feed conveyor belt 320. The lifting drive 540 is activated, pushing the lifting platform 530 upwards, which in turn lifts the rotary table 510, allowing it to raise the carrier. The bottom surface of the carrier disengages from the contact surface of the feed conveyor belt 320, eliminating the influence of the feed conveyor belt 320's movement on the carrier and preparing for rotation. Once the lifting platform 530 reaches the designated height, the rotation drive 520 is activated, rotating the rotary table 510 90°, adjusting the orientation of the carrier and the plate-shaped material to be parallel to the discharge conveyor belt 420. After rotation, the lifting drive 540 reverses its direction, lowering the lifting platform 530 until the bottom surface of the carrier contacts the discharge conveyor belt 420. The discharge conveyor belt 420 then starts, transporting the carrier and the plate-shaped material to the next process, completing the turning and transfer process.

[0048] By setting up the lifting platform 530 and the lifting drive component 540, the rotary table 510 can be made to not interfere with the transportation of the carrier on the feeding conveyor 300 or the transportation of the carrier on the discharging conveyor when it is not in use, thereby improving the stability of the mechanism.

[0049] Please refer to Figure 2 and Figure 3 The steering mechanism 500 also includes a mounting plate 560 fixedly connected to the two connecting rods 230 on the side opposite to the feed belt, a lifting platform 530 located between the mounting plate 560 and the rotary table 510, and a lifting drive component 540 mounted on the mounting plate 560.

[0050] The mounting plate 560 and the connecting rod 230 can be fixedly connected by bolts, riveting, etc. For example, the mounting plate 560 is bolted to the connecting rod 230. Bolting can enhance the connection strength between the mounting plate 560 and the two connecting rods 230, improve the stability of the mechanism, and, in addition, bolting has the characteristic of being detachable, which facilitates disassembly and maintenance in the future and improves maintenance efficiency.

[0051] A mounting plate 560 is bolted to the two connecting rods 230. The mounting plate 560 is used to fix the lifting drive component 540, avoiding the shaking caused by the lifting drive component 540 being directly suspended in the air. In addition, as an independent component, the mounting plate 560 can be pre-installed on the lifting drive component 540 and then fixed to the connecting rod 230 as a whole, reducing on-site assembly time and improving installation efficiency.

[0052] Please refer to Figure 3 and Figure 4 The mounting plate 560 has a rectangular structure. Each of the four corners of the mounting plate 560 has a guide hole 561 that passes through the mounting plate 560. The lifting platform 530 has a corresponding number of guide columns 531 on the side facing the mounting plate 560. The guide columns 531 are slidably connected to the guide holes 561.

[0053] The guide hole 561 passes through the mounting plate 560, allowing the guide post 531 of the lifting platform 530 to pass through the guide hole 561 and slide up and down under the constraint of the mounting plate 560. This further strengthens the guiding effect of the mounting plate 560 on the lifting platform 530 and its limiting effect in the horizontal direction, increasing the stability and accuracy of the movement of the lifting platform 530.

[0054] In this embodiment, four guide posts 531 are provided. One end of each guide post 531 is firmly connected to the lifting platform 530, and the other end is slidably connected to the guide hole 561. The guide posts 531 can be made of high-precision cylindrical metal rods with polished surfaces to reduce the coefficient of friction with the inner wall of the guide hole 561. The diameter of the guide post 531 is precisely matched to the inner diameter of the guide hole 561, and the gap between them is controlled within a very small range. This ensures that the guide post 531 can move flexibly while providing precise guidance when sliding within the guide hole 561.

[0055] Please refer to Figure 3 The mounting plate 560 also has a through first clearance hole 562 in the middle. The lifting drive component 540 is a cylinder. The cylinder is bolted to the side of the mounting plate 560 facing away from the lifting platform 530. The piston rod of the cylinder passes through the first clearance hole 562 and is connected to the side of the lifting platform 530 facing the mounting plate 560.

[0056] In this embodiment, the lifting drive component 540 is a cylinder. In the structure of the mounting plate 560, a first clearance hole 562 is added in its middle, which is through-hole and vertically penetrates the mounting plate 560. The shape of the first clearance hole 562 can be circular, square, or rectangular, for example, circular, to match the piston rod of the cylinder. The cylinder body is bolted to the side of the mounting plate 560 facing away from the lifting platform 530; the piston rod at the other end can smoothly pass through the first clearance hole 562 and connect to the lifting platform 530. This connection method makes the lifting drive component 540, the first clearance hole 562, and the lifting platform 530 form a continuous transmission structure. At the same time, the first clearance hole 562 cooperates with the four guide holes 561, ensuring the movement space of the lifting drive component 540 and providing stable guidance for the lifting platform 530.

[0057] Please refer to Figure 3 and Figure 4 The mounting plate 560 also has a through second clearance hole 563, which is located on one side of the first clearance hole 562. The lifting platform 530 is provided with a through third clearance hole 532 corresponding to the second clearance hole 563. The rotating drive component 520 passes through the second clearance hole 563 and the third clearance hole 532 in sequence and is connected to the rotating component 550.

[0058] In this embodiment, the rotary drive component 520 is a rotary motor. The main function of the second clearance hole 563 is to provide installation space for the main body of the rotary motor, and the main function of the third clearance hole 532 is to provide space for the transmission path of the rotary motor. The output shaft of the rotary motor passes through the third clearance hole 532 and connects to the rotating component 550, thereby forming a complete transmission structure with the rotary motor, the rotating component 550, and the rotary table 510. In addition, the design of the second clearance hole 563 and the third clearance hole 532 can avoid interference between the rotary motor and the cylinder, and improve the structural integration.

[0059] Please continue to refer to this. Figure 4 The lifting platform 530 has a rectangular structure. On the side of the lifting platform 530 that faces the rotating platform 510, two support columns 533 are arranged at intervals on either side of the lifting platform 530.

[0060] In this embodiment, the lifting platform 530 is rectangular, with two support columns 533 spaced apart along its four edges, for a total of eight support columns 533, evenly distributed on the surface of the lifting platform 530. The bottom of each support column 533 is fixed to the surface of the lifting platform 530, and its top can contact the rotating platform 510, thus supporting the rotating platform 510 and preventing it from sagging. The height of the eight support columns 533 is kept approximately the same, with a tolerance of less than or equal to 0.1 mm, ensuring uniform force distribution on the rotating platform 510.

[0061] When the lifting platform 530 rises, the eight support columns 533 simultaneously lift the rotating platform 510 to bear the weight of the rotating platform 510 and the vehicle. During rotation, the support columns 533 offset the radial force and overturning moment of the rotating platform 510 through rigid contact, preventing the platform from deforming or tilting, and ensuring the positional stability of the vehicle when turning.

[0062] Please refer to Figure 5 The rotary table 510 has a regular octagonal structure. On the circumferential direction of the rotary table 510, positioning components 511 are alternately arranged on the inner edge of the surface of the rotary table 510. Each positioning component 511 includes two positioning posts 512 arranged at intervals.

[0063] In other words, the four inner edges of the rotary table 510 are provided with positioning components 511, each including two positioning posts 512 spaced apart. There is a gap between the two positioning posts 512. The carrier has a frame structure, and a cross-shaped connecting frame is provided in the middle of the carrier. The gap between the two positioning posts 512 is wider than the width of the connecting frame, thus the positioning posts 512 can lock the connecting frame, thereby limiting the horizontal displacement of the carrier and improving rotational stability.

[0064] Please refer to Figure 1 Each feed roller assembly 310 includes a feed drive roller and multiple feed driven rollers. Two feed drive rollers are arranged opposite each other, and a feed drive shaft 330 is connected between the two feed drive rollers. The feed drive shaft 330 is connected to a feed drive assembly 340.

[0065] In this embodiment, each side of the feeding roller assembly 310 is provided with a feeding drive wheel, and one side of the feeding drive wheel is provided with multiple feeding driven wheels. The two sides of the feeding roller assembly 310 are connected by a feeding drive shaft 330. Specifically, two feeding drive wheels are connected to each end of the feeding drive shaft 330. At the same time, the feeding drive shaft 330 is connected to a feeding drive assembly 340, which includes a feeding drive driven wheel sleeved on the feeding drive shaft 330, a feeding drive motor mounted on the support frame 200, a feeding drive main wheel connected to the output shaft of the feeding drive motor, and a feeding synchronous belt sleeved on the feeding drive main wheel and the feeding drive driven wheel. When the feeding drive motor starts, the output shaft of the feeding drive motor drives the feeding drive main wheel to rotate, thereby driving the feeding synchronous belt and the feeding drive driven wheel to move. As a result, the feeding drive shaft 330 rotates accordingly, thereby driving the feeding roller assembly 310 to move, realizing feeding and conveying.

[0066] Please continue to refer to this. Figure 1 Each discharge roller assembly includes a discharge drive roller and multiple discharge driven rollers. Two discharge drive rollers are arranged opposite each other, and a discharge drive shaft 430 is connected between the two discharge drive rollers. The discharge drive shaft 430 is connected to a discharge drive assembly 440.

[0067] In this embodiment, each side of the discharge roller assembly is equipped with a discharge drive wheel, and one side of the discharge drive wheel is equipped with multiple discharge driven wheels. The two sides of the discharge roller assembly are connected by a discharge drive shaft 430. Specifically, two discharge drive wheels are connected to each end of the discharge drive shaft 430. At the same time, the discharge drive shaft 430 is connected to a discharge drive assembly 440, which includes a discharge drive driven wheel sleeved on the discharge drive shaft 430, a discharge drive motor mounted on the support frame 200, a discharge drive main wheel connected to the output shaft of the discharge drive motor, and a discharge timing belt sleeved on the discharge drive main wheel and the discharge drive driven wheel. When the discharge drive motor starts, the output shaft of the discharge drive motor drives the discharge drive main wheel to rotate, thereby driving the discharge timing belt and the discharge drive driven wheel to move. As a result, the discharge drive shaft 430 rotates accordingly, thereby driving the discharge roller assembly to move, realizing the material feeding and conveying.

[0068] In some embodiments, a limit switch is provided on the support frame 200 in the conveying direction of the feeding conveyor 300. The limit switch can be a lever-type limit switch. When the carrier moves with the plate-shaped material to a preset position, the carrier can press the trigger rod of the limit switch to send a carrier arrival signal to the control system. The control system then controls the feeding conveyor 300 to stop operating, and the lifting drive 540 and the rotating drive 520 work in sequence to realize the carrier turning. This ensures that the carrier only starts turning after reaching the correct position, improving the turning accuracy.

[0069] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
