Abstract
Description
Technical Field
[0001] The utility model relates to the field of material transportation, in particular to a light-load tooling lifting and conveying device. Background Technique
[0002] Light load usually refers to a special state in which an electronic device or a power system operates when the working load it bears is far lower than its design capacity. This mode can also appear in scenarios such as household appliances, power adapters, industrial equipment, network servers, etc. A conveying device is a mechanical device used to convey items or materials and is widely used in the industrial production field. The light-load conveying device has the advantages of light weight, good mobility, fast transportation speed, etc. The tooling is conveyed by using the light-load conveying device.
[0003] The prior art is applicable to the occasion of lifting and conveying a tooling tray with a weight less than 30 kg and a tray size within 640 mm×640 mm. When the synchronous belt conveyor moves to the upper layer, it aligns with the peripheral upper conveyor line to receive the upper-layer tooling tray into this device. Then, the synchronous belt conveyor together with the tooling tray is transported to the lower layer by the descent of the cylinder. The lower layer is aligned with the peripheral lower conveyor line, and the synchronous belt conveyor sends the tooling tray onto the peripheral lower conveyor line; the up-and-down circulation of the tooling tray can be realized by using two sets of this device and the upper and lower two peripheral conveyor lines.
[0004] The space occupancy rate of the overall structure of the tooling lifting and conveying device lifted by the rodless cylinder in the above-mentioned device is too large, especially obvious in the height direction. Assuming the lifting height increases by H, the overall structure needs to increase by 2H in the height direction. Moreover, the cantilever length of the lifting component in the conventional tooling lifting and conveying device is small (the corresponding width of the tooling tray is 400 mm). Once it exceeds this value, abnormal conditions such as shaking of the lifting component and unsmooth lifting movement will occur.
[0005] In summary, there is an urgent need for a light-load tooling lifting and conveying device with a shortened conveying stroke and a balancing function to solve the above problems. Content of the Utility Model

The double-headed butterfly door stoppers 22 contact the protective door 21. By starting the cylinder 4 to drive the lifting plate 6, the lifting frame 9 and the sliding block 10 to shift, the tooling tray is conveyed. The cooperation of the first chain 8 and the first idler pulley 7 achieves the purpose of shortening the stroke of the cylinder 4 and reducing the pressure on the cylinder 4. The guide rods 5 are used to guide the lifting plate 6.
[0024] As Figures 4 - 5 shown in the figure, it further includes a motor 11, a second chain 12, a rotating shaft 13, a protective sleeve 14, a conveying mechanism 15 and a protective frame 17. A conveying mechanism 15 is mounted on the lifting frame 9. The conveying mechanism 15 is composed of a housing, pulley wheels, a flat belt and a rotating rod. The housing is detachably provided on the lifting frame 9. The housing is in a square shape. Rotating rods are symmetrically and rotatably provided inside the housing. Pulley wheels are connected to both the front and rear ends of the rotating rod. A protective frame 17 is connected to the front side surface of the inner circle of the conveying mechanism 15. A rotating shaft 13 is rotatably connected to the conveying mechanism 15. Pulley wheels are connected to both the front and rear ends of the rotating shaft 13. The two pulley wheels are respectively located at the central positions on the front and rear sides of the conveying mechanism 1. A flat belt is wound around the three pulley wheels on the same side of the front and rear of the conveying mechanism 1. A protective sleeve 14 is connected between the conveying mechanism 15 and the protective frame 17. The protective sleeve 14 is rotatably connected to the rotating shaft 13. A motor 11 is mounted on the rear side surface of the protective frame 17. Runner wheels are provided on both the output shaft of the motor 11 and the rotating shaft 13. Both runner wheels are located inside the protective frame 17. A second chain 12 is wound between the runner wheels on the output shaft of the motor 11 and the rotating shaft 13. By starting the motor 11 to drive the components inside the conveying mechanism 15 to operate, the conveying mechanism 15 can drive the tooling tray to shift.
[0025] As Figure 6As shown in the figure, it further includes a mounting piece 18, a second idler wheel 19 and a third chain 20. The mounting piece 18 is symmetrically connected to the upper and lower sides of the rear side inside the placing frame 1.

[0026] As Figure 4 shown in the figure, it further includes a buffer stopper 23. The buffer stopper 23 is slidably connected to the right side of the conveying mechanism 15, and the buffer stopper 23 can buffer the tooling tray.
[0027] The number of this device is set to two, which are respectively installed between the left and right sides of the upper and lower conveyor lines. The telescopic rod of the cylinder 4 is set to the extended state initially. First, start the motor 11. The output shaft of the motor 11 rotates to drive the second chain 12 to rotate. The second chain 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the internal components of the conveying mechanism 15 to operate. The upper conveyor line drives the tooling tray to shift to the right, so that the tooling tray shifts onto the conveying mechanism 15. The buffer stopper 23 can buffer the tooling tray to prevent the tooling tray from shifting excessively under the conveying inertia of the upper conveyor line. The conveying mechanism 15 places the conveyed tooling tray. Start the cylinder 4. The shortening of the telescopic rod of the cylinder 4 drives the lifting plate 6 to move downward. The lifting plate 6 drives the lifting frame 9 and the sliding block 10 to move downward through the first chain 8 and the first idler pulley 7. The lifting frame 9 drives the conveying mechanism 15 and the tooling tray to move downward to the lower conveyor line. The guide rod 5 is used to guide the lifting plate 6. The lower conveyor line drives the tooling tray to shift to the left, so that the tooling tray shifts onto another conveying mechanism 15. The cooperation of the lifting plate 6, the first chain 8 and the first idler pulley 7 achieves the purpose of shortening the stroke of the cylinder 4, reducing the pressure of the cylinder 4, and increasing the service life of the equipment. Start the cylinder 4 on another device. The extension of the telescopic rod of the cylinder 4 drives the lifting plate 6 to move upward. The lifting plate 6 drives the lifting frame 9 and the sliding block 10 to move upward through the first chain 8. The lifting frame 9 drives the conveying mechanism 15 and the tooling tray to move upward to the upper conveyor line. The upper conveyor line conveys the tooling tray to the right again to the initial conveying mechanism 15. In this way, the up and down reflux of the tooling tray can be realized. The lifting frame 9 and the conveying mechanism 15 will drive the second idler pulley 19 to shift on the third chain 20 during the up and down shifting process, which can support the lifting component and ensure the smooth and stable lifting movement of the lifting frame 9 and the conveying mechanism 15. When it is necessary to repair the inside of the placement frame 1, open the protective door 21 by rotating it through the longitudinal groove. The double-headed butterfly door stopper 22 is disengaged from the placement frame 1, and then the repair operation can be carried out. After the repair operation is completed, push the protective door 21 towards the placement frame 1. The protective door 21 will gradually close under the magnetic attraction of the double-headed butterfly door stopper 22 until it is closed. The double-headed butterfly door stopper 22 can make the protective door 21 more stable and quiet when closing, and automatically align and close the protective door 21 through the magnetic force effect.
