Description

Technical Field

[0001] The present invention belongs to the technical field of material conveying, and relates to a material rotating and flipping integrated machine and a material flipping mechanism thereof. Background Art

[0002] When flat materials conveyed by a conveyor belt are subjected to various processing operations, angle deviation correction is required to keep the deflection angles of each product consistent. Moreover, when encountering flat materials on different planes, a 180° flip is also needed to ensure that the flat materials face the same direction.

[0003] Existing material flipping devices, such as a Chinese patent that discloses an online intermittent 180-degree high-speed flipping device for flat products [Application No.: 202111438264.1], can flip flat materials by 180° and ultimately maintain the direction consistency of each flat product. However, the relative reverse rotation of the two conveyor belts needs to be achieved through auxiliary drive components arranged on both sides of the flipping disk. The auxiliary drive components are cross-linked between the two sides of the flipping disk, resulting in complex structures on both sides of the flipping disk, redundant parts, and the complex cross-linked structure of the auxiliary drive components causing the flipping disk to be too heavy, resulting in excessive inertial load of the flipping disk and high energy consumption during startup and shutdown. Summary of the Invention

[0004] The object of the present invention is to provide a material flipping mechanism for a material rotating and flipping integrated machine in view of the above problems.

[0005] Another object of the present invention is to provide a material rotating and flipping integrated machine.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A material flipping mechanism for a material rotating and flipping integrated machine includes a flipping frame arranged on a frame. Both sides of the flipping frame are respectively connected to the frame through rotating shafts. A rotation drive component is provided between the flipping frame and the frame. Two relatively parallel conveyor belt modules are arranged on the flipping frame. A gap for conveying flat products is formed between the two conveyor belt modules. A conveyor belt drive component capable of simultaneously driving the two conveyor belts to rotate in opposite directions is provided on one side of the two conveyor belt modules.

[0007] The conveyor belt drive component is centrally arranged on one side of the flipping frame and is integrated on one side. The one-side drive avoids double-sided occupation, has a simpler structure, can effectively eliminate redundant components on the opposite side, greatly reduces the total number of parts, makes the structure more compact, and the one-side drive mode shortens the transmission path to reduce the number of transmission stages. By reducing the total number of parts and the number of transmission stages, the overall weight of the flipping frame can be effectively reduced, the moment of inertia of the flipping frame is significantly reduced, and the dynamic response speed and comprehensive energy efficiency of the flipping frame can be effectively improved.

[0008] In the material turnover mechanism of the above-mentioned material rotary and turnover integrated machine, the conveyor belt drive assembly includes two driven wheels arranged on one side of two conveyor belt modules. The two driven wheels are respectively connected to the driving shafts of the two conveyor belt modules. The two driven wheels are connected to one end of a synchronous belt. And on one side of the two driven wheels, there is an auxiliary wheel that can make the synchronous belt pass through the two driven wheels in an S shape and drive them to rotate. A transfer wheel is rotatably connected to the rotating shaft. The other end of the synchronous belt is sleeved on the transfer wheel, and the transfer wheel is connected to a transfer wheel drive unit.

[0009] The operation of the transfer wheel drive unit can drive the transfer wheel to rotate to drive the synchronous belt to rotate. The auxiliary wheel is used to make the synchronous belt pass through the two driven wheels in an S shape to drive the driving shafts of the two conveyor belt modules to rotate in opposite directions, so that the two conveyor belts rotate in opposite directions. The driving structure of the two conveyor belts is simple, with fewer transmission stages, and can effectively improve the dynamic response speed and comprehensive energy efficiency of the turnover rack.

[0010] In the material turnover mechanism of the above-mentioned material rotary and turnover integrated machine, the synchronous belt includes any one of a double-sided tooth synchronous belt, a flat belt or a round belt. The auxiliary wheel, the transfer wheel and the driven wheel cooperate with the synchronous belt.

[0011] In the material turnover mechanism of the above-mentioned material rotary and turnover integrated machine, the conveyor belt module includes a conveyor belt frame. A driving shaft and a driven shaft are arranged on the conveyor belt frame. A conveyor belt is sleeved between the driving shaft and the driven shaft. The auxiliary wheel is connected to the conveyor belt frame of any one conveyor belt module.

[0012] The operation of the synchronous belt can drive the two driving shafts to rotate in opposite directions, so that the two conveyor belts rotate in opposite directions, so that the flat product moves along the conveying direction in the gap.

[0013] In the material turnover mechanism of the above-mentioned material rotary and turnover integrated machine, the turnover rack includes rotating shaft fixing seats located on both sides of the conveyor belt module. A gap height adjusting assembly capable of adjusting the gap height is arranged between the rotating shaft fixing seat and the conveyor belt module.

[0014] The gap height adjusting assembly can flexibly adjust the height of the gap to adapt to flat products of different thicknesses and improve the applicability.

[0015] In the material turnover mechanism of the above-mentioned material rotary and turnover integrated machine, at least one auxiliary roller is further arranged between the driving shaft and the driven shaft. The height of the auxiliary roller exceeds the outer edge connection line of the driving shaft and the driven shaft, so that the conveyor belt forms an arch.

[0016] The arches formed on the conveyor belts can perform adaptive tension adjustment, achieving high-precision and high-stability transmission of flat products. An easy-entry entrance is formed between the arches on the two conveyor belts, which allows flat products to enter the gap easily.

[0017] In the material turning mechanism of the above-mentioned material rotating and turning machine, the rotating drive assembly includes a rotating synchronous wheel arranged on the other side of the two conveyor belt modules, the rotating synchronous wheel is sleeved on the rotating shaft and is circumferentially limited and connected to the rotating shaft, and the rotating synchronous wheel is connected to the rotating drive unit.

[0018] The operation of the rotary drive unit can drive the rotary synchronous wheel to rotate, thereby driving the rotating shaft to rotate to drive the turning frame to rotate 180 degrees on the frame to turn the flat product 180 degrees.

[0019] A material rotating and flipping machine comprises a frame and an adjusting conveying belt arranged on the frame, wherein the output end of the adjusting conveying belt is connected to the discharging conveying belt, and a material flipping mechanism of the material rotating and flipping machine is arranged between the adjusting conveying belt and the discharging conveying belt, and a high-speed four-axis material adjusting manipulator is also arranged on one side of the adjusting conveying belt.

[0020] After angle correction and flipping, the flat products are conveyed to the discharge conveyor belt, which can ultimately maintain the direction consistency of each flat product, facilitate the subsequent processing of the flat products, and thus ensure the processing quality of the products.

[0021] The high-speed four-axis material adjustment robot can adjust the position of the flat product in the width direction of the conveyor belt so that the flat product is located in the center position in the width direction of the conveyor belt after the angle correction is completed. The centralized adjustment can eliminate the accumulated deviations between multi-station flat products to ensure accurate positioning of subsequent processing, and can adapt to conveyor belts of different widths.

[0022] In the above-mentioned material rotation and flipping integrated machine, the high-speed four-axis material adjustment robot includes a robot mounting seat arranged on a frame, an X-axis moving mechanism is provided between the robot mounting seat and the frame, an adsorber is provided on the robot mounting seat, and the adsorber is connected to the robot mounting seat in turn through an adsorber rotation assembly and a Z-axis lifting mechanism, and a Y-axis shifting mechanism is provided between the Z-axis lifting mechanism and the robot mounting seat, which can be used to adjust the position of the flat product in the width direction of the conveyor belt after the adsorber adsorbs the flat product.

[0023] The Y-axis displacement mechanism can adjust the position of the flat product in the width direction of the adjustable conveyor belt so that the flat product is located at the central position in the width direction of the adjustable conveyor belt after the angle deviation correction. Through the centering adjustment, the deviation accumulation between multi-station flat products can be eliminated to ensure the precise positioning of subsequent processing, and it can be adapted to adjustable conveyor belts of different widths.

[0024] In the above-mentioned material rotating and flipping integrated machine, the Y-axis displacement mechanism includes a Y-axis slider and slide rail assembly arranged between the manipulator mounting seat and the Z-axis lifting mechanism. An eccentric drive assembly for driving it to move along the Y-axis is provided between the Z-axis lifting mechanism and the manipulator mounting seat. The eccentric drive assembly includes a drive wheel located at one end of the Y-axis slider and slide rail assembly and rotatably connected to the manipulator mounting seat. The drive wheel is connected to a drive wheel drive unit, and a connecting rod is connected between the drive wheel and the Z-axis lifting mechanism at a position deviating from the rotation center.

[0025] The drive wheel drive unit can drive the drive wheel to rotate. When the drive wheel rotates, the connecting rod at a position deviating from the rotation center on the drive wheel can drive the Z-axis lifting mechanism to move along the Y-axis on the manipulator mounting seat through the Y-axis slider and slide rail assembly, thereby driving the adsorber to move along the width direction of the adjustable conveyor belt to adjust the position of the flat product in the width direction of the adjustable conveyor belt.

[0026] Compared with the existing technology, the advantages of the present invention are as follows: 1. The material flipping mechanism adopts unilateral integration, and the unilateral drive avoids bilateral occupation. The structure is simpler, and the redundant components on the opposite side can be effectively omitted, greatly reducing the total number of parts and making the structure more compact. And the unilateral drive mode shortens the transmission path to reduce the number of transmission stages. By reducing the total number of parts and the number of transmission stages, the overall weight of the flipping frame can be effectively reduced, and the moment of inertia of the flipping frame is significantly reduced, which can effectively improve the dynamic response speed and comprehensive energy efficiency of the flipping frame. 2. It can adjust the position of the flat product in the width direction of the adjustable conveyor belt so that the flat product is located at the central position in the width direction of the adjustable conveyor belt after the angle deviation correction. Through the centering adjustment, the deviation accumulation between multi-station products can be effectively eliminated to ensure the precise positioning of subsequent processing.

Detailed implementation manners Embodiment 1

[0029] As Figures 1-4 shown, a material turning mechanism of a material rotation and turning integrated machine includes a turning frame 5 arranged on a frame 1. Both sides of the turning frame 5 are connected to the frame 1 through a rotating shaft 6 respectively. A rotation drive assembly 7 is arranged between the turning frame 5 and the frame 1. Two relatively parallel conveyor belt modules 8 are arranged on the turning frame 5. A gap 9 for conveying flat products is formed between the two conveyor belt modules 8. A conveyor belt drive assembly 11 capable of simultaneously driving two conveyor belts 10 to rotate in opposite directions is arranged on one side of the two conveyor belt modules 8.

[0030] In the present invention, the operation of the conveyor belt transmission assembly 11 can simultaneously drive the two conveyor belts 10 to rotate in opposite directions, so that the flat products move along the conveying direction in the gap 9, and the operation of the rotary drive assembly 7 can drive the flip frame 5 to rotate 180° on the frame 1 to flip the flat products on different surfaces 180°, and then the flat products are conveyed out of the gap 9.

[0031] The conveyor belt drive assembly 11 is centrally arranged on one side of the turning frame 5, and adopts one-sided integration and one-sided drive to avoid double-sided occupancy. The structure is simpler and can effectively eliminate redundant components on the opposite side, greatly reducing the total number of parts and making the structure more compact. The one-sided drive method shortens the transmission path to reduce the number of transmission stages. By reducing the total number of parts and the number of transmission stages, the overall weight of the turning frame 5 can be effectively reduced, and the rotational inertia of the turning frame 5 can be significantly reduced, which can effectively improve the dynamic response speed and comprehensive energy efficiency of the turning frame 5.

[0032] Specifically, combined with Figures 1-3 As shown, the conveyor belt transmission assembly 11 includes two driven wheels 13 arranged on one side of the two conveyor belt modules 8, the two driven wheels 13 are respectively connected to the driving shafts 14 of the two conveyor belt modules 8, the two driven wheels 13 are connected to one end of a synchronous belt 15, and an auxiliary wheel 16 is provided on one side of the two driven wheels 13, which can make the synchronous belt 15 pass through the two driven wheels 13 in an S shape and drive them to rotate, a rotating wheel 17 connected to the rotation shaft 6 is provided, the other end of the synchronous belt 15 is sleeved on the rotating wheel 17, and the rotating wheel 17 is connected to the rotating wheel driving unit 18.

[0033] The operation of the intermediate wheel driving unit can drive the intermediate wheel 17 to rotate to drive the synchronous belt 15 to rotate. The auxiliary wheel 16 is used to make the synchronous belt 15 pass through the two driven wheels 13 in an S shape to drive the driving shafts 14 of the two conveyor belt modules 8 to rotate in opposite directions, thereby making the two conveyor belts 10 rotate in opposite directions. The driving structure of the two conveyor belts 10 is simple, with a small number of transmission stages, which can effectively improve the dynamic response speed and comprehensive energy efficiency of the turning frame 5.

[0034] Specifically, combined with Figures 1-3 As shown, the rotating wheel 17 is a double wheel, the first tooth portion 19 of the rotating wheel 17 is meshed with the synchronous belt 15 , and the second tooth portion 20 of the rotating wheel 17 is connected to the rotating wheel driving unit 18 .

[0035] The transfer wheel driving unit 18 includes a transfer wheel driver 21 and a transfer conveyor belt 22 . The second tooth portion 20 of the transfer wheel 17 and the output end of the transfer wheel driver 21 are transmitted via the transfer conveyor belt 22 .

[0036] Specifically, combined with Figures 1-3As shown, the synchronous belt 15 includes any one of a double-sided toothed synchronous belt, a flat belt, or a round belt. The auxiliary wheel 16, the transfer wheel 17, and the driven wheel 13 cooperate with the synchronous belt 15.

[0037] Specifically, in combination with Figures 1-4 As shown, the conveyor belt module 8 includes a conveyor belt frame 23. An active shaft 14 and a driven shaft 24 are provided on the conveyor belt frame 23. A conveyor belt 10 is sleeved between the active shaft 14 and the driven shaft 24. The auxiliary wheel 16 is connected to the conveyor belt frame 23 of any one conveyor belt module 8.

[0038] The operation of the synchronous belt 15 can drive the two active shafts 14 to rotate in opposite directions, so that the two conveyor belts 10 rotate in opposite directions, enabling the flat product to move along the conveying direction within the gap 9.

[0039] Preferably, in combination with Figure 1 and Figure 4 As shown, a tensioning structure 25 is further provided between the auxiliary wheel 16 and the conveyor belt module 8. The tensioning structure 25 includes a tensioning adjustment sliding groove 26 opened on the conveyor belt frame 23. A tensioning adjustment shaft 27 is slidably connected within the tensioning adjustment sliding groove 26. The auxiliary wheel 16 is rotatably connected to the tensioning adjustment shaft 27. The tensioning adjustment shaft 27 can slide and be fixed within the tensioning adjustment sliding groove 26 to flexibly adjust the position of the auxiliary wheel 16 for adjusting the tension of the synchronous belt 15.

[0040] By adjusting the tension, it is ensured that the synchronous belt 15 is fully engaged with the auxiliary wheel 16, the transfer wheel 17, and the driven wheel 13, avoiding tooth slip due to insufficient tension, and ensuring the transmission accuracy and synchronism.

[0041] Specifically, in combination with Figures 1-6 As shown, the flipping frame 5 includes rotating shaft fixing seats 28 located on both sides of the conveyor belt module 8. A gap height adjustment component 29 capable of adjusting the height of the gap 9 is provided between the rotating shaft fixing seats 28 and the conveyor belt module 8.

[0042] The gap height adjustment component 29 can flexibly adjust the height of the gap 9 to adapt to flat products of different thicknesses, improving the applicability.

[0043] Specifically, in combination with Figure 5 and Figure 6 As shown, the gap height adjustment component 29 includes a reverse-threaded screw 30. Height adjustment through slots 31 corresponding to each other and threadedly connected to the reverse-threaded screw 30 are respectively opened on the two conveyor belt modules 8. The reverse-threaded screw 30 passes through the two height adjustment through slots 31. Both ends of the reverse-threaded screw 30 are threadedly connected to the two height adjustment through slots 31 respectively.

[0044] Guide grooves 32 adapted to the rotating shaft fixing seat 28 are provided on the outer sides of the two conveyor belt modules 8, height adjustment fixing grooves 33 adapted to the two conveyor belt modules 8 are provided on both sides of the rotating shaft fixing seat 28, bolt holes 34 matched with the height adjustment fixing grooves 33 are provided on the conveyor belt modules 8, and the rotating shaft fixing seat 28 and the conveyor belt modules 8 are fixed by bolts passing through the height adjustment fixing grooves 33 and the bolt holes 34.

[0045] The guide groove 32 includes a guide slide groove 84 symmetrically arranged on the outer side of the conveyor belt module 8, the bolt hole 34 is arranged in the guide slide groove 84, the rotating shaft fixing seat 28 is symmetrically provided with a guide slider 85 that slides with the guide slide groove 84, and the height adjustment fixing groove 33 passes through the guide slider 85.

[0046] The guide slide block 85 of the rotating shaft fixing seat 28 and the guide slide groove 84 of the conveyor belt module 8 are slidably matched to guide the movement of the conveyor belt module 8 .

[0047] When the fixing bolts are not inserted, the two conveyor belt modules 8 can be moved closer or farther away from each other by rotating the reverse threaded screw 30 to adjust the height of the gap 9. The height adjustment fixing groove 33 and the reverse threaded screw 30 cooperate to guide the displacement of the conveyor belt module 8. After the height of the gap 9 is adjusted, the bolts are inserted into the height adjustment fixing groove 33 and the bolt hole 34 in turn to achieve fixation between the rotating shaft fixing seat 28 and the conveyor belt module 8.

[0048] Specifically, combined with Figures 2-5 As shown, at least one auxiliary roller 35 is provided between the driving shaft 14 and the driven shaft 24 , and the height of the auxiliary roller 35 exceeds the connecting line of the outer edges of the driving shaft 14 and the driven shaft 24 , so that the conveyor belt 10 is arched.

[0049] The height of the auxiliary roller 35 exceeds the outer edge connecting line of the driving shaft 14 and the driven shaft 24, so that the conveyor belt 10 is arched. The arched conveyor belt 10 can perform adaptive tension adjustment, thereby realizing high-precision and high-stability transmission of flat products.

[0050] An easy-entry entrance 82 for facilitating the entry of flat products into the gap 9 is formed between the arches on the two conveyor belts 10 , and a clearance notch 83 adapted to the easy-entry entrance 82 is provided on the conveyor belt frame 23 .

[0051] Specifically, combined with Figure 1 and Figure 2 As shown, the rotary drive assembly 7 includes a rotary synchronous wheel 37 arranged on the other side of the two conveyor belt modules 8. The rotary synchronous wheel 37 is sleeved on the rotating shaft 6 and is circumferentially limitedly connected to the rotating shaft 6. The rotary synchronous wheel 37 is connected to the rotary drive unit 38.

[0052] The rotation drive unit 38 can drive the rotation synchronous wheel 37 to rotate, thereby driving the rotating shaft 6 to rotate to drive the turning frame 5 to rotate 180° on the frame 1 to turn the flat product 180°.

[0053] The rotation driving unit 38 comprises a rotation driver 39 , and the output end of the rotation driver 39 is transmitted to the rotation synchronous wheel 37 via a rotation transmission belt 40 .

[0054] like Figures 1-14 As shown, a material rotating and flipping machine includes a frame 1 and an adjusting conveyor belt 2 arranged on the frame 1, the output end of the adjusting conveyor belt 2 is connected to the discharging conveyor belt 3, and a material flipping mechanism 4 of the material rotating and flipping machine is arranged between the adjusting conveyor belt 2 and the discharging conveyor belt 3, and a high-speed four-axis material adjustment robot 12 is also arranged on one side of the adjusting conveyor belt 2.

[0055] In the present invention, flat products enter from the input end of the adjusting conveyor belt 2 in sequence and move along the conveying direction of the adjusting conveyor belt 2. During the movement of the flat products, the high-speed four-axis material adjustment robot 12 performs angle correction adjustment on the flat products and adjusts their position in the width direction of the adjusting conveyor belt 2, so that the flat products are located at the center position in the width direction of the adjusting conveyor belt 2 after the angle correction is completed. Then the flat products are conveyed from the output end of the adjusting conveyor belt 2 to the material turning mechanism 4, and the flat products are conveyed to the gap 9. The operation of the conveyor belt transmission component 11 can simultaneously drive the two conveyor belts 10 to rotate in opposite directions, so that the flat products move in the gap 9 along the conveying direction. The operation of the rotary drive component 7 can drive the turning frame 5 to rotate 180° on the frame 1 to turn the flat products on different surfaces 180°, and then the flat products are conveyed to the discharge conveyor belt 3 for the next processing.

[0056] A material discharge chute 86 is provided at the bottom of the output end of the adjusting conveyor belt 2 and the entrance of the gap 9 . The material discharge chute 86 covers the input end of the discharging conveyor belt 3 and the exit of the gap 9 . The end of the material discharge chute 86 is connected to the side chute 87 .

[0057] The unloading chute 86 and the side chute 87 are used to receive and guide out the flat products that have not successfully entered the gap 9 or have not successfully entered the unloading conveyor belt 3 .

[0058] After the angle correction and the eccentric flipping, the flat products are conveyed to the discharging conveyor belt 3, which can ultimately maintain the direction consistency of each flat product, facilitate the subsequent processing of the flat products, and thus ensure the processing quality of the products.

[0059] The conveyor belt drive assembly 11 is centrally arranged on one side of the tipping frame 5, adopting single-side integration. Single-side drive avoids double-side occupation, making the structure simpler. It can effectively eliminate redundant components on the opposite side, greatly reducing the total number of parts and making the structure more compact. Moreover, the single-side drive mode shortens the transmission path to reduce the number of transmission stages. By reducing the total number of parts and the number of transmission stages, the overall weight of the tipping frame 5 can be effectively reduced, significantly reducing the moment of inertia of the tipping frame 5 and effectively improving the dynamic response speed and comprehensive energy efficiency of the tipping frame 5.

[0060] The high-speed four-axis material adjustment manipulator 12 can adjust the position of the flat product in the width direction of the adjustment conveyor belt 2 so that the flat product is located at the central position in the width direction of the adjustment conveyor belt 2 after the angle deviation correction. Through the centralized adjustment, the deviation accumulation between multi-station flat products can be eliminated to ensure the accurate positioning of subsequent processing and can be adapted to adjustment conveyor belts 2 of different widths.

[0061] Specifically, as shown in Figures 7-11 In the material rotation and tipping integrated machine, the high-speed four-axis material adjustment manipulator 12 includes a manipulator mounting seat 41 arranged on the frame 1. There is an X-axis movement mechanism 42 between the manipulator mounting seat 41 and the frame 1. An adsorber 43 is arranged on the manipulator mounting seat 41. The adsorber 43 is successively connected to the manipulator mounting seat 41 through an adsorber self-rotation assembly 44 and a Z-axis lifting mechanism 45. There is a Y-axis displacement mechanism 46 between the Z-axis lifting mechanism 45 and the manipulator mounting seat 41, which can be used to adjust the position of the flat product in the width direction of the adjustment conveyor belt 2 after the adsorber 43 adsorbs the flat product.

[0062] The X-axis movement mechanism 42 and the Y-axis displacement mechanism 46 can respectively drive the adsorber 43 to move above the adjustment conveyor belt 2 along the length direction and width direction of the adjustment conveyor belt 2 so that the adsorber 43 is located directly above the product to be corrected. The X-axis movement mechanism 42 then makes the adsorber 43 move synchronously with the product to be corrected along the conveying direction according to the conveying speed of the adjustment conveyor belt 2. Then, the Z-axis lifting mechanism 45 drives the adsorber 43 to descend so that the adsorber 43 adsorbs the product to be corrected. Subsequently, the adsorber self-rotation assembly 44 drives the adsorber 43 to rotate, thereby driving the product to be corrected to rotate until the product to be corrected rotates to a unified deflection angle. At the same time, the Y-axis displacement mechanism 46 adjusts the position of the flat product in the width direction of the adjustment conveyor belt 2 so that the flat product after the deviation correction angle is located at the central position in the width direction of the adjustment conveyor belt 2.

[0063] The Y-axis displacement mechanism 46 can adjust the position of the flat product in the width direction of the adjustable conveyor belt 2 so that the flat product is located at the central position in the width direction of the adjustable conveyor belt 2 after the angular deviation correction. Through the centering adjustment, the deviation accumulation between multi-station flat products can be eliminated to ensure the accurate positioning of subsequent processing, and it can be adapted to adjustable conveyor belts 2 with different widths.

[0064] Specifically, as shown in Figures 7-11 , in the material rotating and flipping integrated machine, the Y-axis displacement mechanism 46 includes a Y-axis slider and slide rail assembly 47 arranged between the manipulator mounting seat 41 and the Z-axis lifting mechanism 45. An eccentric drive assembly 48 for driving it to move along the Y-axis is provided between the Z-axis lifting mechanism 45 and the manipulator mounting seat 41. The eccentric drive assembly 48 includes a drive wheel 49 located at one end of the Y-axis slider and slide rail assembly 47 and rotatably connected to the manipulator mounting seat 41. The drive wheel 49 is connected to a drive wheel drive unit 50, and a connecting rod 51 is connected to the Z-axis lifting mechanism 45 at a position deviating from the rotation center of the drive wheel 49.

[0065] The drive wheel drive unit 50 can drive the drive wheel 49 to rotate. When the drive wheel 49 rotates, the connecting rod 51 at the position deviating from the rotation center of the drive wheel 49 can drive the Z-axis lifting mechanism 45 to move along the Y-axis on the manipulator mounting seat 41 through the Y-axis slider and slide rail assembly 47, thereby driving the adsorber 43 to move along the width direction of the adjustable conveyor belt 2 to adjust the position of the flat product in the width direction of the adjustable conveyor belt 2.

[0066] Specifically, as shown in Figure 9 and Figure 10 , one end of the connecting rod 51 is connected to the slide seat 52 of the Z-axis lifting mechanism 45. A drive wheel relief groove 53 is provided at one end of the slide seat 52 where the drive wheel 49 is located. Part of the drive wheel 49 is located in the drive wheel relief groove 53, and the slide seat 52 is connected to the Y-axis slider and slide rail assembly 47; The drive wheel drive unit 50 includes a drive wheel driver 54 arranged at the bottom end of the manipulator mounting seat 41. The output end of the drive wheel driver 54 passes through the manipulator mounting seat 41 to the upper end of the manipulator mounting seat 41. A drive gear 55 is sleeved on the output end of the drive wheel driver 54. A drive tooth body 56 is provided on the drive wheel 49, and the drive gear 55 and the drive tooth body 56 are connected by a drive belt 57.

[0067] When the drive wheel driver 54 operates, it can drive the drive gear 55 to rotate. The rotation of the drive gear 55 can drive the drive wheel 49 to rotate through the drive belt 57. The drive wheel relief groove 53 provides a clearance space for the drive wheel 49 to play a relieving role. When the drive wheel 49 rotates, the connecting rod 51 can drive the slide seat 52 to move along the Y-axis on the manipulator mounting seat 41 through the Y-axis slider and slide rail assembly 47.

[0068] Specifically, in combination with Figures 9-12 As shown, the Z-axis lifting mechanism 45 includes a sliding seat 52 connected to the Y-axis shifting mechanism 46. The sliding seat 52 is connected to a lifting motor plate 58. On the lifting motor plate 58, a driving pulley 59 and a driven pulley 60 for lifting are arranged vertically on the Z-axis. The driving pulley 59 and the driven pulley 60 for lifting are connected by a lifting belt 61. The driving pulley 59 is connected to a driving wheel driver 62. The adsorber self-rotating assembly 44 is connected to one side of the lifting belt 61 through a lifting connecting member 63.

[0069] When the driving wheel driver 62 operates, it can drive the driving pulley 59 to rotate, thereby driving the lifting belt 61 to rotate. When the lifting belt 61 rotates, it can drive the adsorber self-rotating assembly 44 to lift through the lifting connecting member 63, thereby driving the adsorber 43 to lift.

[0070] Preferably, in combination with Figure 9 As shown, on the lifting motor plate 58, limit posts 64 that cooperate with the lifting connecting member 63 are respectively arranged below the driving pulley 59 and above the driven pulley 60 for lifting.

[0071] The cooperation between the limit posts 64 and the lifting connecting member 63 constitutes a mechanical hard limit for the lifting stroke, which can prevent damage caused by overtravel.

[0072] Specifically, in combination with Figures 9-13 As shown, the adsorber self-rotating assembly 44 includes a spline shaft 65. The adsorber 43 is arranged at the bottom end of the spline shaft 65. A connecting bearing 66 is sleeved on the upper end of the spline shaft 65. Both ends of the connecting bearing 66 are fixed by fixing rings 67 sleeved on the spline shaft 65. The inner ring of the connecting bearing 66 is connected to the spline shaft 65, and the outer ring of the connecting bearing 66 is connected to a connecting rotating groove 68 of the lifting connecting member 63. The fixing jaws 69 of the lifting connecting member 63 are clamped on one side of the lifting belt 61.

[0073] The lifting connecting member 63 is rotatably connected to the spline shaft 65 through the connecting rotating groove 68 and the connecting bearing 66. The fixing jaws 69 of the lifting connecting member 63 are clamped on one side of the lifting belt 61 for fixation. When the lifting belt 61 rotates, it can drive the spline shaft 65 to lift through the lifting connecting member 63 to drive the adsorber 43 to lift.

[0074] Specifically, in combination with Figures 9-14As shown, a rotating fixed plate 70 is provided at the bottom end of the lifting motor plate 58, and a connecting groove 71 is provided on the rotating fixed plate 70. A spline nut 72 is sleeved on the lower end of the spline shaft 65, and a plurality of convex strips 73 distributed along its axial direction are provided on the spline nut 72. A groove 74 which is axially slidingly matched with the convex strips 73 and circumferentially rotationally limited is provided on the spline nut 72. A rotating pulley shaft 75 is sleeved on the spline nut 72, and the rotating pulley shaft 75 is arranged in the connecting groove 71 through a bearing seat 76 sleeved thereon. A pulley rotating driver 77 is provided on the rotating fixed plate 70, and the output end of the pulley rotating driver 77 is connected to the rotating pulley shaft 75 through a pulley belt 78.

[0075] The convex strip 73 on the spline shaft 65 and the groove 74 on the spline nut 72 are axially slidably matched and circumferentially rotationally limited. When the lifting belt 61 rotates, the lifting connection 63 can drive the spline shaft 65 to slide in the spline nut 72 to drive the adsorber 43 to rise and fall. The pulley rotation driver 77 runs through the pulley belt 78 to drive the rotating pulley shaft 75 to rotate on the bearing seat 76, thereby driving the spline nut 72 and the spline shaft 65 to rotate to realize the rotation of the adsorber 43, so as to perform the correction operation of the flat product.

[0076] Preferably, combined Figure 8 and Figure 9 As shown, the lifting motor plate 58 is provided with a plurality of first positioning screw holes 79, and the X-axis sliding plate 80 of the X-axis moving mechanism 42 is provided with a second positioning screw hole 81 that matches the first positioning screw hole 79. The lifting motor plate 58 and the X-axis sliding plate 80 can be fixed by positioning bolts passing through the first positioning screw holes 79 and the second positioning screw holes 81.

[0077] The lifting motor plate 58 and the X-axis sliding plate 80 can be fixedly connected. When the lifting motor plate 58 and the X-axis sliding plate 80 are fixedly connected, the adjustment robot does not have the function of adjusting the position of the flat product in the width direction of the transmission belt, and can be selected according to actual conditions.

[0078] The working principle of the present invention is as follows: flat products enter from the input end of the adjusting conveyor belt 2 in sequence and move along the conveying direction of the adjusting conveyor belt 2. During the movement of the flat products, the adsorber 43 adsorbs the flat products and then rotates the products to a uniform deflection angle. At the same time, the driving wheel driver 54 drives the driving wheel 49 to rotate. The connecting rod 51 on the driving wheel 49 drives the slide 13 to move along the Y-axis on the manipulator mounting seat 41, thereby driving the adsorber 43 to move along the width direction of the adjusting conveyor belt 2, so that the products are located at the center position of the width direction of the adjusting conveyor belt 2 after the angle correction is completed. Then the flat product is conveyed from the output end of the adjusting conveyor belt 2 to the material turning mechanism 4, and the flat product is conveyed to the gap 9. The conveyor belt transmission component 11 runs and drives the two conveyor belts 10 to rotate in opposite directions at the same time, so that the flat product moves along the conveying direction in the gap 9. The rotation drive component 7 runs and drives the turning frame 5 to rotate 180° on the frame 1 to turn the flat products on different surfaces 180°. Then the flat product is conveyed to the discharge conveyor belt 3 for the next processing. Embodiment 2
