Description

Technical Field

[0001] This utility model belongs to the field of blade aligning machines, and particularly relates to a blade aligning machine. Background Technology

[0002] In the blade manufacturing industry, the production process for batch blades typically includes: blade alignment (transfer from the feed tray to the carrier tray), carrier tray stacking and storage, and transfer to the processing section. In existing technologies, the alignment machine primarily focuses on blade alignment and carrier tray stacking, while the carrier tray transfer stage faces significant technical bottlenecks, specifically as follows:

[0003] After the existing tray stacking machine completes the stacking of carrier trays, the trays full of blades need to be manually moved one by one to the subsequent processing section. Manual operation is not only time-consuming and labor-intensive, leading to a longer production line cycle time, but also poses a risk of workplace injuries to operators due to the sharp edges of the blades, which does not meet the safety and efficiency requirements of automated production.

[0004] There is a lack of automated transfer interfaces between the assembling machine and subsequent processing sections. The stacked pallets cannot be directly connected to the loading station of the processing equipment via mechanical structures, requiring manual operations such as "unstacking, handling, and positioning," resulting in a discontinuous production process.

Furthermore, terms such as "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] like Figures 1 to 14 As shown, the blade aligning machine provided in this embodiment includes a first frame 1, a tray conveyor line 4, a carrier tray conveyor line 5, a first transfer component 6, a carrier tray transfer chamber 7, a carrier tray transfer component 8, a tray 2, and a carrier tray 3. The tray conveyor line 4, the carrier tray conveyor line 5, the first transfer component 6, and the carrier tray transfer component 8 are all disposed on the first frame 1. The tray conveyor line 4 and the carrier tray conveyor line 5 are arranged side by side. The tray 2 is placed on the tray conveyor line 4, and the carrier tray 3 is placed on the carrier tray conveyor line 5. The transfer end of the first transfer component 6 is located above the tray conveyor line 4 and the carrier tray conveyor line 5. The first transfer component 6 is used to remove the blades from the tray 2 and place them on the carrier tray 3. The carrier tray transfer component 8 is disposed between the carrier tray conveyor line 5 and the transfer chamber and is used to transfer the carrier tray 3, which is full of blades, from the carrier tray conveyor line 5 to the transfer chamber. The tray conveyor line 4 in this embodiment adopts the same structure as the storage tray conveyor line 4 disclosed in application number CN202210814806.9. The tray conveyor line 4 is used to stack and store trays 2 filled with blades, recycle empty trays 2, and convey trays 2 filled with blades to the front end. During alignment, the tray 2 filled with blades is conveyed forward by the tray conveyor line 4, and then the blades in the tray 2 are removed by the first transfer component 6 and placed at the empty tray 3 of the carrier tray conveyor line 5. When the current carrier tray 3 is full of blades, the carrier tray conveyor line 5 drives the carrier tray 3 and the blades to move backward. When loading processing is required, the carrier tray transfer component 8 transfers the placement tray 9 carrying the carrier tray 3, the carrier tray 3, and the blades together to the carrier tray transfer bin 7, waiting for subsequent loading processing. This system enables the automatic alignment and transfer of blades from material tray 2 to carrier tray 3, eliminating the need for manual tray placement and handling. Through the carrier transfer component 8 combined with the carrier transfer chamber 7, it can seamlessly interface with processing equipment, significantly improving production efficiency and safety while reducing labor costs and operational risks. The blade alignment machine in this implementation interfaces with a double-end face grinder, which operates in an oil mist environment.

[0043] The tray transfer assembly 8 is a conveyor belt with two parallel conveying sections 81, separated by a first clearance space 82. The tray 3, loaded with blades, along with the placement tray 9, is stored above the front end of the tray transfer assembly 8. When loading is required, the tray 3, loaded with blades, along with the placement tray 9, is lowered onto the conveyor belt 81 via the tray conveyor line 5, and then conveyed backward by the conveyor belt 81 to the tray transfer bin 7.

[0044] The tray transfer compartment 7 includes a second frame 71, and a conveyor roller assembly 72, a lifting frame 73, a first tray rack 74, a transfer platform 75, and a second transfer assembly 76 disposed on the second frame 71. The conveyor roller assembly 72 is located between the tray transfer assembly 8 and the transfer platform 75. The second transfer assembly 76 is used to transfer the tray 3 from the conveyor roller assembly 72 to the transfer platform 75. The first tray rack 74 is disposed at the rear end of the conveyor roller assembly 72 in the conveying direction, and the tray storage area of ​​the first tray rack 74 is located above the conveyor roller assembly 72 and the lifting frame 73. The lifting frame 73 is disposed below the conveyor roller assembly 72, and its lifting end can extend through the conveyor roller assembly 72 to the tray storage area of ​​the first tray rack 74. The placement tray 9, together with the tray 3 and its blades, is conveyed from front to back by the conveyor roller assembly 72 until it is conveyed to the rear end. Then, the second transfer assembly 76 transfers the tray 3 on the placement tray 9, together with the blades, to the transfer platform 75. After the carrier tray 3 detaches from the placement tray 9, the lifting frame 73 rises, pushing the placement tray 9 upwards until it is stored in the storage rack. Then, the lifting frame 73 moves downwards to reset. This not only achieves the transfer of the carrier tray 3, providing a buffer transition and ensuring the continuity of the production line, but also, through the combination of the lifting frame 73 and the storage rack, enables the unified collection and orderly storage of the placement trays 9. This avoids the space waste and inconvenience caused by the random stacking of placement trays 9, making the workshop layout more rational. The systematic storage of placement trays 9 by the storage rack allows workers to quickly locate and retrieve the required placement trays 9, reducing search time and shortening the loading cycle of the carrier tray 3. Furthermore, the orderly storage of placement trays 9 reduces mutual collisions and wear, extending their service life and reducing equipment maintenance costs. The storage rack is located above the conveyor roller assembly 72 and the lifting frame 73, adopting a three-dimensional spatial layout that effectively utilizes the vertical space of the equipment and reduces the floor space required. The coordinated design of the lifting frame 73 and the conveying roller assembly 72 allows the placement tray 9 to be directly conveyed upward to the storage rack via the lifting frame 73 after the carrier tray 3 is detached, without the need for additional transportation equipment, thus simplifying the logistics path.

[0045] The conveyor roller assembly 72 includes a first mounting frame 721, a conveyor roller body 722, a first limiting plate 723, a threaded fastener 724, a first telescopic cylinder 725, and a push block 726. The conveyor roller body 722 is mounted on the first mounting frame 721. The first mounting frame 721 has first strip-shaped holes 727 on both the left and right sides of its top. The first limiting plate 723 has second strip-shaped holes 728. The first limiting plate 723 is detachably fixed to the top of the first mounting frame 721 by threaded fasteners 724, which pass through the first strip-shaped holes 727 and the second strip-shaped holes 728. The first limiting plate 723 is located above the conveyor roller body 722. At least one side of the top of the first mounting frame 721 is fixed with a first telescopic cylinder 725. The inner end of the first telescopic cylinder 725 is fixed with a push block 726, which is located above the conveyor roller body 722. The rear end of the conveyor roller body 722 in the conveying direction has a second clearance space 729 for the lifting end of the lifting frame 73 to pass through. The front ends of the first limiting plate 723 and the first mounting frame 721 both have guide inclined walls 7210, which are located above the conveyor roller body 722. In this embodiment, the first limiting plate 723 is only provided on the left side of the top of the first mounting frame 721. In other embodiments, it may be only provided on the right side of the top of the first mounting frame 721, or the first limiting plate 723 may be provided on both the left and right sides. The first limiting plate 723 can be adjusted left and right by the cooperation of the first slot 727, the second slot 728, and the threaded fastener 724 to adapt to the operational needs of placement trays 9 of different widths. In this embodiment, the threaded fastener 724 is a combination of bolt and nut. The second clearance space 729 provides clearance for the lifting frame 73, ensuring the normal operation of the lifting frame 73 and the conveyor roller body 722. The guide inclined wall 7210 serves as a guide for conveying. In other embodiments, the first telescopic cylinder 725 may be fixed to the right side of the top of the first mounting frame 721, or the first telescopic cylinder 725 may be fixed to both the left and right sides of the top of the first mounting frame 721. When the placement tray 9 is conveyed to the rear end of the conveyor roller body 722, the conveyor roller body 722 stops moving, and then the first telescopic cylinder 725 extends, driving the push block 726 to move to the right, pushing the placement tray 9 to the right so that it is directly below the storage area.

[0046] The lifting frame 73 includes a second telescopic cylinder 731, a first connecting seat 732, a vertical pole 733, a second connecting seat 734, a first linear bearing 735, a first guide shaft 736, and a support bar 737. The second telescopic cylinder 731 is fixed to the second frame 71. The first connecting seat 732 is fixed to the top of the second telescopic cylinder 731. The vertical pole 733 is fixed to the first connecting seat 732. The second connecting seat 734 is fixed to the bottom of the vertical pole 733. The first guide shaft 736 is fixed to the second connecting seat 734. The first linear bearing 735 is fixed to the frame. The top of the first guide shaft 736 passes through the first linear bearing 735 and is fixed with the support bar 737. When the placement tray 9 needs to be moved upward, the second telescopic cylinder 731 extends, causing the first connecting seat 732 to move upward, which in turn causes the upright 733 to move upward, which in turn causes the second connecting seat 734 to move upward, which in turn causes the first guide shaft 736 to move upward, which in turn causes the support bar 737 to move upward, thus pushing the placement tray 9 upward. The cooperation of the first linear bearing 735 and the first guide shaft 736 improves the smoothness of lifting. In this embodiment, there are four first linear bearings 735 and four first guide shafts 736, distributed at the four corners of the second connecting seat 734, further improving the smoothness of lifting.

[0047] The second material transfer assembly 76 includes a first linear module 761, a second linear module 762, a slide cylinder 763, and a push column 764. The first linear module 761 is fixed to the second frame 71. The second linear module 762 is fixed to the moving end of the first linear module 761. The slide cylinder 763 is fixed to the moving end of the second linear module 762. The push column 764 is fixed to the sliding end of the slide cylinder 763. The push column 764 is located above the transfer platform 75 and the conveying roller assembly 72. During material transfer, the first linear module 761 drives the second linear module 762 and the slide cylinder 763 to move forward to above the placement tray 9. Then, the slide cylinder 763 drives the push column 764 to move downward to the center hole in the middle of the carrier tray 3. The first linear module 761 drives the push column 764, along with the carrier tray 3 and the blade, to move backward, transferring the carrier tray 3 and the blade together to the transfer platform 75. Then, according to the requirements, the first linear module 761 stops moving at a suitable position, and the second linear module 762 drives the carrier tray 3 and the blade together to move to the left to place the carrier tray 3.

[0048] The first storage frame 74 includes a second mounting frame 741, a torsion spring shaft 742, a hinge seat 743, a swing block 744, and a limiting post 745. The second frame 71 on both the left and right sides of the conveyor roller assembly 72 is fixed with the second mounting frame 741. The second mounting frame 741 is fixed with the hinge seat 743. The swing block 744 is hinged to the hinge seat through the torsion spring shaft 742. The swing block 744 is located above the conveyor roller assembly 72. The limiting post 745 can be detachably connected to both the front and rear sides of each second mounting frame 741. Initially, under the action of the torsion spring shaft 742, the swing block 744 is horizontally abutting against the second mounting bracket 741. As the placement tray 9 is pushed upward, it pushes the swing block 744 upward until it reaches above the swing block 744. The swing block 744 then swings downward to reset under the action of the torsion spring shaft 742. Then, the support bar 737 moves downward, and under gravity, the placement tray 9 moves downward until it is placed on top of the swing block 744. This process is repeated to complete the orderly storage of the placement tray 9. This design eliminates the need for complex drive mechanisms, relying on mechanical linkage and gravity. It simplifies the storage process of the placement tray 9, reduces equipment costs, improves space utilization, and ensures storage stability, effectively preventing the placement tray 9 from slipping or stacking haphazardly. This greatly enhances the automation and practicality of the tray transfer chamber 7. The placement tray 9 is limited by the limiting post 745 to ensure effective stacking and prevent it from tipping over during stacking.

[0049] The tray conveyor line 5 includes a third linear module 51, a tray transfer frame 52, a second tray storage frame 53, and a support frame 54. The third linear module 51, the second tray storage frame 53, and the support frame 54 are all fixed to the first frame 1. There are two second tray storage frames 53, spaced apart along the conveying direction of the tray 3. The rearmost second tray storage frame 53 is located at the front end of the tray transfer assembly 8. Each of the two second tray storage frames 53 is equipped with a support frame 54. The moving end of the third linear module 51 is fixed with a tray transfer frame 52. In this embodiment, the second tray storage frame 53 adopts the same structure as the first tray frame disclosed in application number CN202411245271.3; the support frame 54 adopts the same structure as the support frame 54 disclosed in application number CN202411245271.3. The second storage rack 53 located at the front is used to store empty trays 3 and placement trays 9, with the empty tray 3 placed on the placement tray 9. The second storage rack 53 located at the rear is used to store trays 3 and placement trays 9 that are full of blades. When tray stacking is required, the third linear module 51 moves the tray transfer frame 52 to below the second storage rack 53 at the front. Through the cooperation of the support frame 54 and the second storage rack 53, the empty tray 3 and placement tray 9 are placed on the tray transfer frame 52. Then, the third linear module 51 moves the tray transfer frame 52 forward to the tray stacking station. When the blades are full, the third linear module 51 moves the tray transfer frame 52 backward to the second storage rack 53 at the rear. Through the cooperation of the support frame 54 and the second storage rack 53, the tray 3 full of blades, along with the placement plate, is pushed upward onto the second storage rack 53 for stacking and storage. When feeding is required, the carrier 3, which is full of blades, moves downward along with the placement plate to the conveyor belt 81 through the cooperation of the support frame 54 and the second storage rack 53, and is then conveyed backward by the conveyor belt 81.

[0050] The transfer frame 52 includes a third mounting frame 521, a second linear bearing 522, a second guide shaft 523, a third telescopic cylinder 524, a transfer plate 525, a fourth telescopic cylinder 526, and a second limiting plate 527.

The top of the third telescopic cylinder 524 is fixed with the transfer plate 525, which can pass through the first clearance space 82. The transfer plate 525 is fixed with the second guide shaft 523, and the bottom end of the second guide shaft 523 passes through the second linear bearing 522. The front and rear sides of the bottom of the transfer plate 525 are fixed with the fourth telescopic cylinder 526. The telescopic end of the fourth telescopic cylinder 526 is fixed with the second limiting plate 527, and the top of the second limiting plate 527 extends upward to the top of the transfer plate 525. When it is necessary to remove the empty tray 3 and the placement tray 9 from the second storage rack 53 on the front side, the third telescopic cylinder 524 extends, driving the transfer tray 525 to move upward until the top wall of the transfer tray 525 abuts against the placement tray 9. Then, the fourth telescopic cylinder 526 retracts, driving the second limiting plates 527 on the front and rear sides to move closer together, clamping the placement tray 9. Combined with the third linear module 51, the tray transfer rack 52 and its upper structure are transported forward to the tray placement station.

[0051] The first material transfer assembly 6 includes a fourth linear module 61, a fourth mounting frame 62, a fifth linear module 63, and a quick-change robot 64. The fourth linear module 61 is fixed to the first frame 1, the fourth mounting frame 62 is fixed to the moving end of the fourth linear module 61, at least one fifth linear module 63 is fixed to the fourth mounting frame 62, and the quick-change robot 64 is fixed to the moving end of the fifth linear module 63. The quick-change robotic arm 64 includes a servo motor 641, a base 642, a rotary joint 643, an angular contact bearing housing 644, a rotating shaft 645, a mounting base 646, a quick-change base 647, and a pneumatic clamp 648. The servo motor 641, the rotary joint 643, and the angular contact bearing housing 644 are all fixed to the base 642. The servo motor 641 is connected to the rotating shaft 645 through the rotary joint 643. The bottom end of the rotating shaft 645 passes through the angular contact bearing housing 644 and is fixed to the mounting base 646. The quick-change base 647 is detachably connected to the mounting base 646, and the pneumatic clamp 648 is detachably connected to the quick-change base 647.

[0052] During material handling, the fourth linear module 61 drives the fourth mounting bracket 62 and its upper structure to move to the right above the material tray 2. Then, the fifth linear module 63 drives the quick-change robot 64 to move downward into the center hole of the blade in the material tray 2. The blade is held by the clamping end of the pneumatic clamp 648. Then, the fifth linear module 63 drives the quick-change robot 64 to move upward, so that the blade moves upward and leaves the material tray 2. The servo motor 641 drives the pneumatic clamp 648 to rotate a certain angle as needed, causing the blade to rotate a certain angle. The fourth linear module 61 moves the blade to the left until it is above the carrier plate 3. Combined with the third linear module 51 moving the carrier plate 3 back and forth until the empty blade edge of the carrier plate 3 is directly below the blade, the tilt angle of the empty blade edge is the same as the tilt angle of the blade. The fifth linear module 63 moves the blade downward until it enters the empty blade edge. The pneumatic clamp 648 resets, and the blade is placed in the empty blade edge. The fifth linear module 63 moves upward to reset, and the fourth linear module 61 moves to the right to reset, thus completing the placement of one blade. The above actions are repeated until the carrier plate 3 is full of blades. In this embodiment, the pneumatic clamp 648 is a thumb cylinder. In other embodiments, it can also be a suction cup clamp or an expansion clamp.

[0053] The rotary joint 643 is placed between the servo motor 641 and the rotating shaft 645, effectively isolating the vibration of the servo motor 641 while efficiently transmitting power, ensuring high precision and stability of the rotational motion. Combined with the servo motor 641, this configuration offers higher precision and stability compared to traditional stepper motors. The angular contact bearing housing 644 and the rotary joint 643 work together to construct a stable rotational support system. The angular contact bearing housing 644 can simultaneously withstand radial and axial loads, effectively distributing the complex forces acting on the rotating shaft 645 during operation and reducing shaft wobble. This dual protection, along with the rotary joint 643, significantly improves the smoothness of the rotating shaft 645's operation, effectively reducing equipment operating noise and wear, extending the overall service life of the equipment, and providing a solid and reliable rotational foundation for the pneumatic clamp 648, ensuring precision and stability during long-term continuous operation. Furthermore, the rotary joint 643 prevents pipelines from becoming entangled. With the detachable connection between the quick-change seat 647 and the mounting seat 646, the pneumatic clamp 648 can be quickly disassembled and replaced without the need for any tools, which significantly improves the efficiency of tooling fixture replacement, reduces equipment downtime, and allows for quick switching of the appropriate pneumatic clamp 648 according to different production tasks, greatly enhancing the versatility and flexibility of the equipment.
