Description

Technical Field

[0001] The present invention relates to the technical field of parts processing, in particular to a multi-station double-guide rail circulation conveying line. Background Art

[0002] With the continuous development of the manufacturing industry, automated production has become the key to improving production efficiency, product quality and reducing costs. In many industries such as automobile manufacturing, electronics manufacturing, and food processing, materials or products need to be transported efficiently and accurately between different workstations to achieve a continuous and automated production process.

[0003] Traditional conveyor lines, such as belt conveyor lines and roller conveyor lines, are gradually unable to meet complex production needs in terms of multiple stations and high-precision positioning. At the same time, single-rail conveyor lines have some limitations, such as poor flexibility and low efficiency. Summary of the Invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a solution to the problem that traditional conveyor lines such as belt conveyor lines, roller conveyor lines, etc. are gradually unable to meet complex production needs in terms of multiple stations and high-precision positioning; another purpose of the present invention is to provide a solution to some limitations of single-rail conveyor lines, such as poor flexibility and low efficiency.

[0005] Technical solution: A multi-station double-guide rail circulating conveying line includes a frame, the upper surface of which is fixedly connected to a double-guide rail circulating conveying platform, the upper surface of which is provided with multiple contour-carrying carriers, and the outer side walls of the multiple contour-carrying carriers are all provided with floating tabletops.

[0006] Furthermore, a plurality of driving gears are provided on the upper surface of the double-guide rail circulating conveying platform, and the outer side walls of the plurality of driving gears are engaged and connected with a chain. A driving motor is provided on the lower surface of the double-guide rail circulating conveying platform, and the top end of the output shaft of the driving motor is fixedly connected to the center of the lower surface of the driving gear on the front right side of the double-guide rail circulating conveying platform.

[0007] Furthermore, a plurality of adjustable legs are fixedly connected to the lower surface of the frame.

[0008] Furthermore, the floating platform includes an upper platform, and a plurality of linear bearings are arranged above the upper platform. A guide column is provided at the center of the lower surface of the plurality of linear bearings. The bottom ends of the plurality of guide columns extend to the bottom of the upper platform and are fixedly connected to a mounting seat. The outer side walls of the plurality of guide columns are sleeved with compression springs, and the lower surfaces of the plurality of mounting seats located on one side are fixedly connected to the lower platform.

[0009] Beneficial effects: The present invention adopts a design that cooperates with a double-guide rail circulating conveying platform and a contour carrier, which effectively solves the problem of insufficient positioning accuracy in multi-station production. The floating platens on the outer sides of the multiple contour carriers can be adaptively adjusted according to the shapes of different workpieces and the requirements of the workstations. Combined with the high-precision double-guide rail structure, it can achieve accurate docking and transfer of materials between different workstations, meeting the stringent requirements of complex production processes for positioning accuracy. At the same time, compared with the traditional conveying method, the transmission method of the chain and the drive gear is more stable and has higher power transmission efficiency. It is not prone to problems such as slipping and deviation, thus providing guarantees for the continuity and reliability of multi-station production.

[0010] When a large-tonnage hydraulic press presses downward, the upper platform of the floating platen bears the brunt of the pressure. This pressure is transmitted to the compression spring and the lower platform through linear bearings and guide columns. The compression spring, by virtue of its own elastic deformation, converts the pressure into elastic potential energy, achieving initial buffering. The lower platform then disperses the remaining pressure to the hydraulic press workbench, forming a dual unloading mechanism of "spring buffering + platform pressure distribution". During this process, the circulating guide rail bears almost no direct pressure from the hydraulic press, avoiding structural damage such as deformation and fracture of the guide rail due to excessive load, significantly extending the service life of the guide rail and reducing the frequency of equipment downtime and maintenance caused by damage to core components.

[0011] The present invention gives the conveyor line greater flexibility through the dual-guide rail design. The two guide rails can control the operation of multiple contour-bearing carriers, realizing differentiated transportation of different carriers between different workstations, greatly improving the flexibility of production scheduling. In addition, multiple contour-bearing carriers can simultaneously carry different materials or products through multiple workstations in parallel. There is no need to wait for the carriers on a single track to complete all processes in sequence like a single-guide rail conveyor line, which significantly improves the overall conveying efficiency and production rhythm, and effectively shortens the product production cycle.

[0015] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] like Figure 1-Figure 2 As shown, a multi-station double-guide rail circulating conveying line is provided, comprising a frame 1, a double-guide rail circulating conveying platform 2 is fixedly connected to the upper surface of the frame 1, a plurality of contour carriers 3 are provided on the upper surface of the double-guide rail circulating conveying platform 2, and a floating platform 4 is provided on the outer side walls of the plurality of contour carriers 3;

[0018] A plurality of drive gears 5 are provided on the upper surface of the dual-guide rail circulating conveying platform 2, and a chain 6 is meshed and connected to the outer side walls of the plurality of drive gears 5. A drive motor 7 is provided on the lower surface of the dual-guide rail circulating conveying platform 2, and the top end of the output shaft of the drive motor 7 is fixedly connected to the center of the lower surface of the drive gear 5 on the front right side of the dual-guide rail circulating conveying platform 2;

[0019] The driving motor 7 is used as the power core. After starting, the output shaft of the driving motor 7 drives the driving gear 5 on the front right to rotate. The driving gear 5 is engaged with the chain 6, and then drives the chain 6 to circulate on multiple driving gears 5. When the chain 6 rotates, it drives multiple profiling carriers 3 set on the upper surface of the double-guide rail circulating conveying platform 2 to move along the double guide rails. The floating table 4 on the outer side wall of the multiple profiling carriers 3 can be flexibly adjusted according to the needs of the workstations during the conveying process to ensure that the workpieces placed thereon are smoothly transferred between different workstations. In a multi-station production scenario, the workpieces are moved along with the multiple profiling carriers 3. The carrier 3 passes through different workstations in sequence to realize various processes such as processing and testing. At the same time, the double-guide rail structure ensures the stability and accuracy of transportation, which can effectively prevent material deviation or falling. The transmission method of the chain 6 and the drive gear 5 has reliable power transmission and can carry heavier workpieces. The setting of multiple contoured carriers 3 and workstations realizes multi-task parallel processing, greatly improving production efficiency. The floating table 4 increases the adaptability to different workpieces and improves the flexibility of the production line. It can meet diversified production needs and is widely applicable to the automated production processes of many industries such as automobile manufacturing and electronic assembly.

[0020] like Figure 1 As shown, a plurality of adjustable legs 8 are fixedly connected to the lower surface of the frame 1;

[0021] In actual use, whether it is a workshop with uneven ground or a scenario where the conveyor line needs to be precisely connected with other equipment, the height of the support legs 8 can be adjusted to ensure that the frame 1 is in a horizontal and stable state, thereby ensuring the smooth operation of the double-rail circulating conveying platform 2, thereby effectively enhancing the adaptability of the conveyor line to complex installation environments, avoiding conveyor line shaking and material deviation due to uneven ground, reducing equipment wear, and extending equipment service life. At the same time, it also provides a guarantee for the seamless connection between the conveyor line and upstream and downstream equipment, further improving the overall stability and reliability of the automated production line.

[0022] like Figure 1As shown, the floating platform 4 includes an upper platform 401, and a plurality of linear bearings 402 are provided above the upper platform 401. A guide column 403 is provided at the center of the lower surface of each of the plurality of linear bearings 402. The bottom ends of the plurality of guide columns 403 extend to the bottom of the upper platform 401 and are fixedly connected to a mounting seat 404. The outer walls of the plurality of guide columns 403 are sleeved with a compression spring 405. The lower surfaces of the plurality of mounting seats 404 on one side are fixedly connected to the lower platform 406.

[0023] During the production process, when the profiling carrier carries the workpiece into the working area of ​​the large-tonnage hydraulic press, the huge pressure generated by the downward pressure of the hydraulic press first acts on the upper platform 401 of the floating table 4. The upper platform 401 is connected to the guide column 403 through multiple linear bearings 402. The pressure will cause the upper platform 401 to move downward along the guide column 403. At this time, the compression spring 405 on the outer wall of the guide column 403 is squeezed and elastically deformed, converting the pressure into elastic potential energy of the spring, which plays a buffering role. At the same time, the mounting seat 404 at the bottom end of the guide column 403 further transmits the pressure to the lower platform 40 6. Finally, the pressure is released to the hydraulic press workbench, so that the pressure on the double-rail circulating conveying platform can be effectively dispersed, avoiding the large-tonnage pressure directly acting on the circulating guide rail, thereby protecting the circulating guide rail from being crushed, and ensuring the normal operation of the conveyor line in a high-pressure production environment, reducing equipment failures and downtime maintenance time caused by guide rail damage, reducing maintenance costs, and ensuring efficient connection between the hydraulic machine processing station and the conveyor line, so that the stability and reliability of the entire automated production line are improved, the service life of the conveyor line is extended, and the continuity and efficiency of production are guaranteed.

[0024] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
