Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a process flow transportation device for processing metal thin plates. Background Art

[0002] Sheet metal plays a vital role in modern industrial production, widely used in a variety of fields, including automotive, aerospace, construction, and home appliances. With the development of the manufacturing industry and increasing demands for product quality, sheet metal processing accuracy and production efficiency have become a focus for manufacturers. Traditional sheet metal processing often requires manual handling or crane transport of workpieces and their transfer between process steps. This not only increases labor intensity, reduces production efficiency, and can easily damage the workpiece.

[0003] To improve the efficiency and quality of sheet metal processing and reduce manual handling costs, automated process flow and transportation devices have emerged. These devices can quickly, accurately, and smoothly transfer workpieces between different processing steps, significantly improving the automation level of the production line. However, existing process flow and transportation devices still have the following problems during use:

[0004] 1. After the metal sheets are transported to the next process through the process flow transportation device, they are unloaded manually. Although the process flow transportation device saves some labor intensity and improves production efficiency, there is still room for improvement;

[0005] 2. After the metal sheets are transported to the next process through the process flow transportation device, they are unloaded by the robot. The transportation device integrated with the robot significantly increases the purchase cost and maintenance difficulty of the device;

[0049] Please see the attached Figures 1 to 6 FIG. 1 is a first embodiment of the present invention, which provides a process flow and transportation device for processing metal sheets, including a frame 10, a drive motor 11 fixed at one end of the frame 10, pulleys 12 fixed at the four end corners of the frame 10, and two pulleys 12 located at one end of the frame 10 are fixedly connected to the output end of the drive motor 11, a transmission belt 13 is installed on the outer side of the two pulleys 12 located on the same side, roller frames 14 are installed on both sides of the frame 10, a plurality of bases 15 are fixed to the upper end of the transmission belt 13, and a bottom plate 16 is fixed to the upper end of the plurality of bases 15, and further comprising:

[0050] The conveying assembly 20 is assembled on the base plate 16. The conveying assembly 20 includes a first shaft 21, a first crank 22, a fixed rod 23, a second shaft 24, a second crank 25, a driven gear 26, a transmission gear 27 and a driving rack 28. The first shaft 21 is rotatably connected to the inside of the base 15 at an end away from the driving motor 11 through a ball bearing. The first crank 22 is fixed to the end of the outer side of the first shaft 21 away from the base 15. The fixed rod 23 is fixed to one side of the base 15, and the fixed rod 23 and the first shaft 21 are rotatably connected. The second shaft 24 is rotatably connected to the end of the inner side of the fixed rod 23 away from the base 16 through a ball bearing. The second crank 25 and the driven gear 26 are both fixed to the outer side of the second shaft 24. The transmission gear 27 is rotatably connected to one side of the fixed rod 23. The driving rack 28 is fixed to one side of the frame 10, and the driven gear 26 and the transmission gear 27 as well as the transmission gear 27 and the driving rack 28 are all meshed.

[0051] Multiple supporting assemblies 30, each of which is mounted on one side of the first crank 22 and the second crank 25 close to the bottom plate 16. The supporting assemblies 30 are capable of carrying metal sheets of different sizes;

[0052] The unloading assembly 40 is provided at one end of the frame 10 away from the driving motor 11 and is used for unloading and storing the metal sheets;

[0053] Among them, the first crank 22, fixed rod 23, second crank 25 and support assembly 30 located on the same side together constitute a parallel four-bar linkage mechanism. When the metal sheet is transported through the base plate 16, when the transmission gear 27 and the drive rack 28 are engaged, the conveying assembly 20 can transfer the metal sheet to the upper end of the unloading assembly 40.

[0054] Please note that Figure 2 and Figure 5 As shown, the transport component 20 is a symmetrical structure. In this embodiment, the symmetry axis of the transport component 20 is used as the boundary, and only the structure on one side of the symmetry axis is described. The structure on the other side of the symmetry axis is symmetrically arranged, and no further details are given here.

[0055] Furthermore, the driving motor 11 is preferably a servo motor to improve the stability and controllability of the device during operation.

[0056] In this embodiment, when a metal sheet (hereinafter referred to as a sheet) is processed and the sheet needs to be transported to the next process, the sheet is placed on the upper end of the base plate 16, and the sheet and the support assembly 30 are adapted to each other, and the drive motor 11 is started. The drive motor 11 drives the pulley 12 and the transmission belt 13 to rotate, thereby driving the base 15 and the base plate 16 to move synchronously. Since the base 15 and the fixed rod 23 and the fixed rod 23 and the transmission gear 27 are connected to each other, the fixed rod 23 and the transmission gear 27 are driven to move by the base 15. When the transmission gear 27 and the driving rack 28 are engaged, the transmission gear 27 is driven to rotate by the driving rack 28, and then the driven gear 26 is driven to rotate by the transmission gear 27. The second shaft rod 24 and the driven gear 26 are fixedly connected, so that the driven gear 26 drives the second shaft rod 24 to rotate. 4 and the second crank 25 are fixedly connected, so that the second shaft 24 drives the second crank 25 to rotate, and then the parallel four-bar linkage composed of the first crank 22, the fixed rod 23, the second crank 25 and the supporting assembly 30 are operated, and the plate is carried and lifted by the parallel four-bar linkage. When the parallel four-bar linkage carries the plate and rotates to the upper end of the unloading assembly 40, the plate carried by the parallel four-bar linkage is unloaded by the unloading assembly 40, so that the plate is stored at the upper end of the unloading assembly 40, so that the device can realize unloading without relying on manual labor or manipulators, thereby improving production efficiency and reducing the purchase cost and maintenance cost of the device. At the same time, by driving the rack 28 as an excuse to drive the parallel four-bar linkage to operate and realize unloading of the plate, there is no need to set an additional drive source for the conveying assembly 20 and the supporting assembly 30, which further reduces the structural complexity of the device.

[0057] Next, please refer to Figure 6 The diameter of the driven gear 26 is recorded as D1, and the diameter of the transmission gear 27 is recorded as D2, D1>D2.

[0058] In this embodiment, through the above-mentioned arrangement, a reduction gear set is formed by the cooperation of the driven gear 26 and the transmission gear 27 to reduce the rotation speed of the parallel four-bar linkage mechanism, thereby avoiding the phenomenon of the plate slipping due to too high a rotation speed during the process of transporting the plate by the parallel four-bar linkage mechanism.

[0059] Furthermore, in actual application, further optimization can be made on the basis of this embodiment. Specifically, the rotation speed of the parallel four-bar linkage can be further reduced by continuing to add gears inside the reduction gear set. The specific adjustment process is carried out according to actual usage requirements and is not further limited here.

[0060] Secondly, please also refer to Figures 7 to 9 The supporting assembly 30 includes a first supporting rod 31, a limiting bushing 32, a threaded sleeve 33, a second supporting rod 34, a third supporting rod 35 and an elastic element 36. The first supporting rod 31 is rotatably connected to the end of the first crank 22 away from the fixed rod 23 through a ball bearing. The limiting bushing 32 is fixed to one end inside the first supporting rod 31. The threaded sleeve 33 is threadedly connected to the outside of the limiting bushing 32. The second supporting rod 34 is slidably connected to the inside of the first supporting rod 31. The third supporting rod 35 is slidably connected to the outside of the second supporting rod 34 and is located at an end away from the first supporting rod 31. The elastic element 36 is assembled between the second supporting rod 34 and the third supporting rod 35. A drag arm 37 is fixed between the third supporting rods 35 inside the two supporting assemblies 30 located on the same side of the base 15. In the initial state, the elastic element 36 is in a compressed state.

[0061] Here, in the supporting assembly 30 connected to the first crank 22 , the first supporting rod 31 is rotatably connected to the inside of the first crank 22 , and in the supporting assembly 30 connected to the second crank 25 , the first supporting rod 31 is rotatably connected to the inside of the second crank 25 .

[0062] Furthermore, the elastic element 36 is preferably a coil spring.

[0063] It should be noted that by rotating the threaded sleeve 33 forward, one end of the limiting bushing 32 can be squeezed by the threaded sleeve 33, and the second supporting rod 34 can be limited by the limiting bushing 32. By rotating the threaded sleeve 33 backward, the squeezing of the limiting bushing 32 by the threaded sleeve 33 can be released, thereby releasing the limitation of the second supporting rod 34 by the limiting bushing 32.

[0064] In this embodiment, before processing the plate, the distance between the two drag arms 37 is adjusted according to the width of the plate after processing in the current process. Specifically, the threaded sleeve 33 is rotated in the opposite direction to release the limit formed by the limit bushing 32 on the second supporting rod 34, and the second supporting rod 34 is slid so that the second supporting rod 34 moves relative to the first supporting rod 31. The third supporting rod 35 and the drag arm 37 are driven to move synchronously by the first supporting rod 31, thereby adjusting the distance between the two drag arms 37 so that the distance between the two drag arms 37 can be adapted to the width of the plate. The two drag arms 37 cooperate to lift metal sheets of different widths, thereby improving the applicability of the device. After the spacing between the two drag arms 37 is adjusted, the threaded sleeve 33 is rotated forward so that the limit bushing 32 limits the second supporting rod 34 again. In the process of transporting the plate to the next process through the device, when the parallel four-bar linkage is operated to move the plate, the two drag arms 37 are used to lift the plate placed on the bottom plate 16, and the plate moves synchronously with the drag arms 37 until the plate moves to the upper end of the unloading assembly 40.

[0065] Next, please refer to Figure 9 The upper end of the drag arm 37 is provided with a supporting surface 3701, and the supporting surface 3701 is adapted to the unloading assembly 40. The lower end of the drag arm 37 is inclinedly provided with a unloading driven surface 3702. The upper end of the drag arm 37 and the upper end of the supporting surface 3701 are provided with a guide surface 3703. The width of the supporting surface 3701 is recorded as L1, and the horizontal projection width of the unloading driven surface 3702 is recorded as L2, and L2>L1.

[0066] In this embodiment, during the process of transporting the plate through the bottom plate 16, when the transmission gear 27 and the driving rack 28 are engaged, the driving rack 28 drives the parallel four-bar linkage to move the plate. When the drag arm 37 contacts the unloading assembly 40, the unloading driven surface 3702 first contacts the unloading assembly 40, and the unloading assembly 40 drives the two drag arms 37 to move away from each other (at this time, the third supporting rod 35 follows the drag arm 37 to move synchronously towards the direction of the second supporting rod 34, and compresses the elastic element 36). When the distance between the two drag arms 37 is greater than the width of the plate, the plate falls to the upper end of the unloading assembly 40, so that the device can unload the plate without relying on manual handling. At the same time, there is no need to set up a robotic arm. When the plates stacked on the upper end of the unloading assembly 40 reach a certain height, the parallel four-bar linkage continues to transport the plates, and the drag arm 37 will give priority to contacting the plates stacked on the upper end of the unloading assembly 40. Since L2>L1, the edges of the stacked plates can drive the two drag arms 37 to move and unload.

[0067] Please refer again Figure 7 and Figure 8As shown, a rotation-stopping surface 38 is provided on the outer side of the second supporting rod 34 , and a plurality of scale marks are evenly arranged on the upper end of the rotation-stopping surface 38 .

[0068] It should be noted that a chamfered surface is provided inside the first supporting rod 31 , and the chamfered surface is matched with the anti-rotation surface 38 .

[0069] In this embodiment, the cooperation between the chamfered surface and the anti-rotation surface 38 can prevent the second supporting rod 34 from rotating when sliding relative to the first supporting rod 31. At the same time, the setting of the scale mark makes it convenient for the staff to accurately adjust the length of the combination of the first supporting rod 31 and the second supporting rod 34, and then accurately adjust the distance between the two dragging arms 37 so that the distance between the two dragging arms 37 can be adapted to the width of the plate.

[0070] Please refer again Figures 10 to 12 The unloading assembly 40 includes a sheet material storage platform 41, a threaded rod 42, two unloading drive plates 43 and a handwheel 44. The sheet material storage platform 41 is arranged at one end of the frame 10 away from the drive motor 11. A guide groove 45 is provided at the upper end of the interior of the sheet material storage platform 41. The threaded rod 42 is rotatably connected to the interior of the sheet material storage platform 41 through a ball bearing and is located inside the guide groove 45. Two external threads are provided on the outer side of the threaded rod 42, and the thread rotation directions of the two external threads are opposite. The two unloading drive plates 43 are both threadedly connected to the outer side of the threaded rod 42. The two unloading drive plates 43 and the two external threads correspond one to one, and the unloading drive plates 43 and the guide groove 45 are slidably connected. The handwheel 44 is fixed to one end of the outer side of the threaded rod 42. The tops of the two unloading drive plates 43 are inclined to provide unloading drive surfaces 46. The inclination directions of the two unloading drive surfaces 46 are opposite, and the unloading drive surfaces 46 are adapted to the unloading driven surface 3702.

[0071] In this implementation, see Figure 12 As shown, the threaded rod 42 is rotated by the handwheel 44, and the threaded connection between the unloading drive plate 43 and the threaded rod 42 is used to make the threaded rod 42 drive the unloading drive plate 43 to move, and then the distance between the two unloading drive plates 43 is adjusted, so that the two unloading drive plates 43 can be adapted to the two drag arms 37 respectively. After the parallel four-bar linkage moves the plate to the upper end of the unloading drive plate 43, the unloading drive plate 43 contacts the drag arm 37, and the unloading drive surface 46 drives the drag arm 37 to move, so that the drag arm 37 no longer supports the plate, and the plate falls to the upper end of the plate storage table 41 and is located between the two unloading drive plates 43, so that the device can automatically unload the plate.

[0072] Please refer again Figure 10 A plurality of size marks are provided on the top of the sheet material storage platform 41 , and the size marks are matched with the unloading drive plate 43 .

[0073] In this embodiment, the provision of the size marking facilitates the staff to accurately and quickly adjust the distance between the two unloading drive plates 43 so that the two unloading drive plates 43 can be adapted to the two dragging arms 37 respectively.

[0074] It should be noted that the distance between the two unloading drive plates 43 needs to be greater than the width of the plate to prevent the unloading drive plates 43 from blocking the plate during the falling process, so that the plate cannot fall smoothly to the upper end of the plate storage table 41.

[0075] The working principle of the present invention is:

[0076] The second supporting rod 34 is moved by rotating the threaded sleeve 33 to release the limit of the limiting bushing 32 on the second supporting rod 34, and the second supporting rod 34 is moved. The length of the combination of the first supporting rod 31 and the second supporting rod 34 is adjusted so that the distance between the two dragging arms 37 can be adapted to the width of the plate. When the plate needs to be transported to the next process, the plate processed in the current process is placed on the upper end of the bottom plate 16, and the two sides of the plate are adapted to the two dragging arms 37 respectively, and the driving motor 11 is started. The pulley 12 and the transmission belt 13 are driven to rotate by the driving motor 11, and then the base 15 and the bottom plate 16 are driven to move synchronously, and the plate is driven to move by the bottom plate 16. Since the base 15 and the fixed rod 23, as well as the fixed rod 23 and the transmission gear 27 are connected to each other, the fixed rod 23 and The transmission gear 27 moves, and when the transmission gear 27 and the driving rack 28 are engaged, the driving rack 28 drives the transmission gear 27 to rotate, thereby causing the parallel four-bar linkage composed of the first crank 22, the fixed rod 23, the second crank 25 and the support assembly 30 to operate, and the two drag arms 37 are used to lift and move the plate on the upper end of the base plate 16. When the parallel four-bar linkage carries the plate to the upper end of the plate storage table 41 and the drag arm 37 contacts the unloading drive surface 46, the unloading drive surface 46 drives the drag arm 37 to move, causing the two drag arms 37 to move away from each other, thereby causing the plate to fall to the upper end of the plate storage table 41 and be located between the two unloading drive plates 43, so that the device can unload the plate without relying on manual labor and robotic arms.

[0077] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
