Description

Technical Field

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

[0002] In the automotive parts manufacturing industry, stamping is a crucial step in forming sheet materials. The efficient transport of stamped sheet materials, such as door panels and engine hoods, is essential for the smooth operation of the entire production process. To improve the transport efficiency of sheet materials, stacking conveyors are typically installed on the conveyor line to stack the stamped sheet materials in multiple layers for batch transport.

[0003] However, current stacking and conveying devices are complex in structure, often employing a collaborative approach of servo motors, precision sensors, and intricate mechanical transmission mechanisms. They typically integrate multiple linear modules, rotary cylinders, and vacuum suction cups. This complex structure leads to high manufacturing costs, hindering low-cost, widespread application. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes an automatic feeding device for automotive parts painting, applied to an automotive parts production line, comprising:

[0006] The conveying mechanism includes a support frame, two conveying tracks, and conveying rollers. The two conveying tracks are respectively arranged on both sides of the support frame. Each conveying track includes a stacking conveying section, and the conveying rollers are arranged in the conveying tracks.

[0007] A stacking mechanism is provided in the stacking conveyor section. The stacking mechanism includes two lifting components symmetrically arranged on opposite sides of the stacking conveyor section. Each of the lifting components includes a support plate and a lifting component connected to the support plate.

[0008] Multiple carriers are used to carry plate-shaped materials. The multiple carriers are laid flat on the two conveying tracks in sequence. When the carriers are located in the stacking conveying section, the two lifting plates can abut against the two ends of the carriers parallel to the conveying direction of the conveying tracks under the drive of the two lifting components.

[0009] In some embodiments, the stacking mechanism further includes:

[0010] Two connecting frames are bolted to the support frame, and the two connecting frames are symmetrically arranged on opposite sides of the stacking conveyor section;

[0011] The two lifting components are slidably connected to the two connecting frames, respectively.

[0012] In some embodiments, any of the connecting frames is a frame structure, and the upper beam of the connecting frame parallel to the conveying track is provided with at least one through guide hole. At least one guide post is fixedly connected to the side of any of the lifting plates facing the guide hole, and the other end of the at least one guide post is slidably connected to the at least one guide hole.

[0013] In some embodiments, two guide holes are provided, and the two guide holes are distributed at intervals on one side of the upper beam of the connecting frame parallel to the conveying track. Two guide posts are provided accordingly, and the two guide posts are distributed at intervals on the side of the lifting plate facing the guide holes. The two guide posts are slidably connected to the two guide holes respectively.

[0014] In some embodiments, a through-hole is provided between the two guide holes. One end of the lifting assembly is fixedly connected to the lower beam of the connecting frame parallel to the conveying track, and the other end of the lifting assembly passes through the through-hole and is connected to the side of the lifting plate opposite to the through-hole.

[0015] In some embodiments, at least two support blocks are spaced apart on the side of the lifting plate opposite to the lifting assembly.

[0016] In some embodiments, in the conveying direction of the conveying track, the conveying track further includes a straight conveying section, which is sequentially connected to the stacking conveying section.

[0032] Please refer to Figure 1 This utility model provides an automatic feeding device 100 for automotive parts painting, comprising:

[0033] The conveying mechanism 200 includes a support frame 210, two conveying tracks 220 and conveying rollers 230. The two conveying tracks 220 are respectively arranged on both sides of the support frame 210, and the conveying track 220 includes a stacking conveying section 222. The conveying rollers 230 are arranged in the conveying track 220.

[0034] The stacking mechanism 300 is located in the stacking conveyor section 222. The stacking mechanism 300 includes two lifting components 301 symmetrically arranged on opposite sides of the stacking conveyor section 222. Each lifting component 301 includes a support plate 320 and a lifting component 310 connected to the support plate 320.

[0035] Multiple carriers 500 are used to carry plate-shaped materials. The multiple carriers 500 are laid flat on two conveying tracks 220 in sequence. When the carriers 500 are located in the stacking conveying section 222, the two lifting plates 320 can abut against the two ends of the carriers 500 parallel to the conveying direction of the conveying track 220 under the drive of the two lifting components 310.

[0036] The main function of the conveying mechanism 200 is to convey plate-shaped materials. The conveying mechanism 200 includes a support frame 210, two sets of conveying tracks 220, and conveying rollers 230. The support frame 210 serves as the basic framework of the entire conveying mechanism 200, providing stable support for the two conveying tracks 220 and other components, ensuring the stability of the mechanism during operation. The support frame 210 can be made of stainless steel or aluminum alloy, etc. For example, the support frame 210 is made of stainless steel, which has strong tensile strength and high rigidity, capable of stably supporting multiple carriers 500 and plate-shaped materials, ensuring smooth operation of the mechanism. Of course, the above is only an example; the specific material can be determined according to actual needs, and this utility model does not impose any limitations.

[0037] Conveying tracks 220 are respectively set on both sides of the support frame 210, including a stacking conveying section 222. The carrier 500 carries plate-shaped materials and is conveyed by the conveying tracks 220. When conveyed to the stacking conveying section 222, multiple carriers 500 can be lifted by the lifting plates 320 for multi-layer stacking and conveying, thereby improving conveying efficiency.

[0038] Conveying rollers 230 are mounted on the conveying track 220 and are responsible for carrying and conveying the carrier 500 and the plate-shaped material. The carrier 500 is driven to move linearly by the rotation of the conveying rollers 230. The outer diameter of the conveying rollers 230 is precisely matched to the width of the conveying track 220 to ensure smooth rolling along the track under external force. The inner side of the conveying track 220 is designed with grooves or guide rails that conform to the shape of the conveying rollers 230, which both guide the conveying rollers 230 and prevent lateral deviation during operation, ensuring the accuracy of the conveying path of the carrier 500.

[0039] A stacking mechanism 300 is installed in the stacking conveyor section 222, which can stack the carriers 500 entering the stacking conveyor section 222 for easy transport. The stacking mechanism 300 includes two lifting components 301 symmetrically arranged on opposite sides of the stacking conveyor section 222. The lifting component 301 includes a support plate 320 and a lifting component 310 connected to the support plate 320. The support plate 320 is in direct contact with the carrier 500 and is responsible for lifting the carrier 500. Among them, the lifting component 310 is the core component for realizing the vertical lifting of the carrier 500. The driving source of the lifting component 310 can be a cylinder or a combination of a flat belt and a motor, etc., as long as precise lifting motion control can be achieved to ensure that the support plate 320 can smoothly and accurately lift the carrier 500 to the specified height. This utility model does not impose any limitations on this.

[0040] The lifting plate 320, as a key component of the carrier 500, can be made of a high-strength, wear-resistant metal material, such as stainless steel. Furthermore, the lifting plate 320 can be a rectangular flat structure, capable of evenly bearing the weight of the material and preventing deformation due to uneven stress. Of course, the above is merely an example; specific designs can be determined according to actual needs, and this utility model does not impose any limitations.

[0041] The main function of the carrier 500 is to carry plate-shaped materials. Multiple carriers 500 are arranged sequentially on the conveyor track 220. The carrier 500 is in direct contact with the conveyor rollers 230. When the conveyor rollers 230 rotate, they drive the carrier 500 in linear motion. The carrier 500 has a rectangular frame structure, which reduces its own weight, thereby reducing the pressure on the conveyor track 220 and the conveyor rollers 230, preventing excessive pressure from damaging the conveyor rollers 230 and extending their service life.

[0042] The two ends of the carrier 500 parallel to the conveying direction of the conveying track 220 can press against the lifting plate 320 respectively. When the lifting plate 320 is driven to rise by the lifting component 310, the lifting plate 320 can abut against the carrier 500 and lift the carrier 500 to rise synchronously, so that a stacking space is left under the carrier 500 of the current stacking conveying section 222, allowing the carrier 500 in the front section to enter the stacking space and form a double-layer stacking structure with the lifted carrier 500.

[0043] In actual operation, when a carrier 500 carrying plate-shaped material is conveyed to the stacking conveyor section 222 via the conveyor track 220, the lifting plate 320 of the stacking mechanism 300, driven by the lifting component 310, smoothly lifts the carrier 500 located in the stacking conveyor section 222, causing the carrier 500 to detach from the surface of the conveyor track 220. At this time, the carrier 500 at the front of the stacking conveyor section 222 continues to be conveyed forward to the stacking conveyor section 222, entering the space below the lifted carrier 500. After the carrier 500 is in place, the lifting component 310 drives the lifting plate 320 to descend, so that the upper carrier 500 is stably stacked on top of the lower carrier 500, forming a double-layer stacked structure. Subsequently, the conveyor roller 230 continues to rotate, conveying the double-layer stacked carrier 500 and plate-shaped material together to the next process.

[0044] The conveying mechanism 200 of this utility model includes a support frame 210, two conveying tracks 220, and conveying rollers 230. The two conveying tracks 220 are arranged on both sides of the support frame 210, and the conveying rollers 230 are arranged in the conveying tracks 220 and rotate to drive the carrier 500 to move linearly. The conveying track 220 includes a stacking conveying section 222, and a stacking mechanism 300 is arranged at the stacking conveying section 222. The stacking mechanism 300 includes lifting plates 320 and lifting components 310 symmetrically arranged on opposite sides of the stacking conveying section 222. When the carrier 500 moves to the stacking conveying section 222 driven by the conveying rollers 230, the lifting plates 320 and 330... Driven by the lifting assembly 310, the 0 can abut against both sides of the carrier 500, thereby smoothly lifting the carrier 500 located in the stacking conveyor section 222. Then, the front carrier 500 is allowed to enter the space below the lifted carrier 500. The lifting assembly 301 drives the lifting plate 320 to descend, and the upper carrier 500 and the lower carrier 500 form a double-layer stacking structure, realizing the rapid stacking and conveying of carriers 500 and plate materials, effectively improving production efficiency. Compared with traditional complex stacking devices, it reduces a large number of precision transmission components and sensors, reduces the cost of parts procurement, processing and assembly, and is easy to apply on a large scale at low cost.

[0045] Please refer to Figure 1 and Figure 2 as well as Figure 4 The stacking mechanism 300 also includes:

[0046] Two connecting frames 330 are bolted to the support frame 210, and the two connecting frames 330 are symmetrically arranged on opposite sides of the stacking conveyor section 222;

[0047] The two lifting components 301 are slidably connected to the two connecting frames 330 respectively.

[0048] The connecting frame 330 is symmetrically arranged on both sides of the stacking conveyor section 222. As a key connecting component between the lifting assembly 301 and the support frame 210, the connecting frame 330 and the support frame 210 can be connected by bolts. For example, the connecting frame 330 and the support frame 210 are fastened with bolts. Bolts can improve the connection stability between the connecting frame 330 and the support frame 210, and facilitate disassembly, which is beneficial for later maintenance and replacement. The connecting frame 330 is made of high-strength metal material, which can not only bear the weight of the lifting assembly 310 and the lifting plate 320, but also effectively resist the lateral forces and vertical pressures generated during the stacking of materials on the carrier 500.

[0049] The lifting component 301 is slidably connected to the connecting frame 330 and can slide vertically relative to the connecting frame 330 to lift the carrier 500 for lifting and lowering movements.

[0050] Please refer to Figure 3 , Figure 4 as well as Figure 5 The connecting frame 330 has a frame structure. The upper beam 333 of the connecting frame 330 parallel to the conveying track 220 is provided with at least one through guide hole 331. At least one guide post 322 is fixedly connected to the side of any lifting plate 320 facing the guide hole 331. The other end of the at least one guide post 322 is slidably connected to the at least one guide hole 331.

[0051] This can be understood as follows: the number of guide holes 331 can be 1, 2, or 3, etc., and the number and position of guide posts 322 are set accordingly to ensure that the guide posts 322 are vertically slidably connected to the guide holes 331. When the number of guide holes 331 is configured as 1, the guide hole 331 can be set on any upper beam 333 of the connecting frame 330; when the number of guide holes 331 is configured as 2, the two guide holes 331 can be set on the same upper beam 333, or they can be set on two separate upper beams 333; when the number of guide holes 331 is configured as 3, the three guide holes 331 can be set simultaneously on the same upper beam 333, or two of them can be located on the same upper beam 333 and the other guide hole 331 can be located on another upper beam 333, or the three guide holes 331 can be set on three different upper beams 333. Of course, the above are just examples, and the specific design can be determined according to actual needs. This utility model does not impose any limitations here.

[0052] The guide hole 331 passes through the upper beam 333 of the connecting frame 330, allowing the guide post 322 of the lifting plate 320 to pass through the guide hole 331 and slide up and down under the constraint of the connecting frame 330. This further strengthens the guiding effect of the connecting frame 330 on the lifting plate 320 and its limiting effect in the horizontal direction, increasing the stability and accuracy of the movement of the lifting plate 320.

[0053] One end of the guide post 322 is firmly connected to the lifting plate 320, and the other end is slidably connected to the guide hole 331. The guide post 322 can be a high-precision cylindrical metal rod with a polished surface to reduce the coefficient of friction with the inner wall of the guide hole 331. The diameter of the guide post 322 is precisely matched with the inner diameter of the guide hole 331, and the gap between them is controlled within a very small range, ensuring that the guide post 322 can move flexibly and provide precise guidance when sliding in the guide hole 331. The number of guide posts 322 matches the number of guide holes 331 and can be set according to the size and load-bearing requirements of the lifting plate 320. There is at least one guide post. When multiple guide posts 322 are set, they are connected to the lifting plate 320 at intervals, which can better ensure the balance and stability of the lifting plate 320 during the lifting process.

[0054] Please continue to refer to this. Figure 4 and Figure 5In order to improve the balance and stability of the lifting plate 320 during the lifting process, two guide holes 331 are provided. The two guide holes 331 are distributed at intervals on the upper beam 333 of the connecting frame 330 parallel to the conveying track 220. Two guide columns 322 are provided accordingly. The two guide columns 322 are distributed at intervals on the side of the lifting plate 320 facing the guide holes 331. The two guide columns 322 are slidably connected to the two guide holes 331 respectively.

[0055] The upper beam 333 of the connecting frame 330 is provided with two guide holes 331 at intervals to allow the connecting frame 330 to adapt to the center of gravity distribution of the carrier 500 and the material on the lifting plate 320. Two guide columns 322 are fixedly connected to the lifting plate 320, also at intervals, and their positions correspond to the guide holes 331, providing stable dual-point support for the lifting plate 320. In addition, the symmetrical guide structure effectively restricts the horizontal degree of freedom of the lifting plate 320, preventing it from shifting during lifting and lowering, and allowing the carrier 500 to be precisely aligned when stacked. Finally, the dual guide structure distributes the load on the lifting plate 320, making the force between the guide columns 322 and the guide holes 331 more even, reducing the wear of individual components and extending the overall service life of the equipment.

[0056] Please refer to Figure 3 and Figure 4 Between the two guide holes 331, there is also a through hole 332 for the upper beam 333. One end of the lifting component 310 is fixedly connected to the lower beam 334 of the connecting frame 330 parallel to the conveying track 220, and the other end of the lifting component 310 passes through the through hole 332 and is connected to the side of the lifting plate 320 facing the through hole 332.

[0057] In this embodiment, the lifting assembly 310 is a cylinder. In the structure of the connecting frame 330, a through hole 332 is added between the two guide holes 331, perpendicularly penetrating the upper beam 333 of the connecting frame 330. The shape of the through hole 332 can be circular, square, or rectangular, for example, circular, to match the telescopic rod of the cylinder. One end of the cylinder is securely connected to the lower beam 334 at the bottom of the connecting frame 330, and the connection strength can be ensured by bolt fixing, welding, etc.; the telescopic rod at the other end can smoothly pass through the through hole 332 and connect to the lifting plate 320. This connection method makes the lifting assembly 310, the through hole 332, and the lifting plate 320 form a continuous transmission structure. At the same time, the through hole 332 cooperates with the guide holes 331 on both sides, which not only ensures the movement space of the lifting assembly 310, but also provides stable guidance for the lifting plate 320.

[0058] Please refer to Figure 5 At least two support blocks 324 are provided at intervals on the side of the lifting part that is away from the lifting assembly 310.

[0059] The support blocks 324, as components in direct contact with the carrier 500, can be 2, 3, or 4 in number. For example, the number of support blocks 324 is 2. Two support blocks 324 are spaced apart on the side of the lifting plate 320 opposite to the guide post 322, ensuring uniform and stable force distribution when the carrier 500 and materials are placed. Furthermore, the shape of the support blocks 324 can be various, including square or round, depending on actual needs; this invention does not impose any limitations. The support blocks 324 are fixedly mounted on the lifting plate 320 with bolts, facilitating disassembly and replacement to adapt to the lifting needs of different types of carriers 500 and materials.

[0060] Please refer to Figure 1 and Figure 2 In the conveying direction of the conveying track 220, the conveying track 220 also includes a straight conveying section 221, which is sequentially connected to a stacking conveying section 222. Both the straight conveying section 221 and the stacking conveying section 222 are equipped with a stopping mechanism 400. A mounting plate is provided between the two corresponding conveying tracks 220 of the straight conveying section 221 and the stacking conveying section 222. The stopping mechanism 400 is bolted to the mounting plate and can rotate in the conveying direction of the conveying track 220. The stopping mechanism 400 blocks and releases the carrier 500 by rotating.

[0061] When the carrier 500, carrying plate-shaped material, moves along the conveyor track 220 to the blocking mechanism 400 of the linear conveyor section 221, the blocking mechanism 400 rotates to the blocking position, pausing the carrier 500 in the current linear conveyor section 221. At this time, if the carrier 500 in the stacking conveyor section 222 has not yet been lifted by the stacking mechanism 300, the blocking mechanism 400 of the linear conveyor section 221 remains in the blocking state, causing the carrier 500 to pause in the linear conveyor section 221, forming an orderly waiting queue. When the carrier 500 in the stacking conveyor section 222 is successfully lifted by the lifting component 301 of the stacking mechanism 300, the blocking mechanism 400 of the linear conveyor section 221 in front of the stacking conveyor section 222 rotates back to its original position, releasing the carrier 500, allowing the carrier 500 to smoothly enter the stacking conveyor section 222. Once the new carrier 500 enters the stacking conveyor section 222, the stopping mechanism 400 of the stacking conveyor section 222 rotates to stop the new carrier 500. After the upper carrier 500 and the new carrier 500 are stacked, the stopping mechanism 400 of the stacking conveyor section 222 activates again, releasing the stacked carrier 500 so that it can continue to be conveyed forward. Through the coordinated operation of the stopping mechanism 400 of the linear conveyor section 221 and the stacking conveyor section 222, the orderly conveying and precise stacking of the carrier 500 and the materials are achieved.

[0062] Please refer to Figure 1 and Figure 6Each of the four corners of any carrier 500 is provided with a positioning part 510. Each positioning part 510 includes two baffles 511 provided on the two adjacent outer sides. Each of the four corners of the carrier 500 is fixedly connected to a positioning post 520 on the side opposite to the positioning part 510. The positioning post 520 of one carrier 500 can abut against the positioning part 510 of another carrier 500 respectively. The two positioning posts 520 located on the same side of the conveying track 220 are fixedly connected to a connecting rod 530.

[0063] Each carrier 500 is provided with a positioning part 510 at each of its four apex corners. Each positioning part 510 is composed of two baffles 511 located on the two adjacent outer sides. The baffles 511 can be made of high-strength metal sheet, such as stainless steel or aluminum alloy, which has good resistance to deformation and can withstand the pressure and impact during the stacking process.

[0064] Positioning posts 520 are fixedly connected to the four corners of the carrier 500 on the side opposite to the positioning part 510. The positioning posts 520 can be made of metal and are connected to the main body of the carrier 500 by welding or bolting to ensure a firm connection. Of course, the above is only an example, and the specific design can be determined according to actual needs. This utility model does not impose any limitations here.

[0065] The connecting rod 530 can be a long strip of metal, and its material can be the same as that of the positioning post 520. The two positioning posts 520 located on the same side of the conveying track 220 are fixedly connected by the connecting rod 530. The two ends of the connecting rod 530 can be welded or bolted to the sides of the positioning posts 520 respectively to form a stable rigid frame structure.

[0066] When one carrier 500 is stacked on top of another carrier 500, the positioning posts 520 of the upper carrier 500 can abut against the positioning parts 510 of the lower carrier 500 to position the upper carrier 500, improving stacking accuracy. Simultaneously, the connecting rods 530 of the upper carrier 500 abut against the lower carrier 500, significantly enhancing the support strength and deformation resistance of the positioning posts 520. During the conveying and stacking of carriers 500, the connecting rods 530 can distribute external forces, preventing excessive stress on individual positioning posts 520 and extending the service life of the carriers 500. This also reduces equipment downtime due to carrier structural damage, improving production efficiency.

[0067] 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.
