[0019] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] The working principle of the gap divider is to convert continuous input rotation into intermittent, precise indexing output through the relative movement between the internal cam and the needle roller bearing. Specifically, when the input shaft rotates continuously, the curved groove on the cam guides the needle roller bearing, or indexing wheel, to perform periodic lifting and rotation, thereby achieving precise stopping and rotation of the output shaft at a specific angle, completing the indexing action, and realizing the intermittent conveying process of the turntable 3.

[0022] Furthermore, the support composite magnetic clamp 11 includes a base, and a blade placement area and a blade holder placement area disposed on the base, with the connection point between the two being a welding point; it also includes a strong magnet disposed on the upper surface of the base frame, the strong magnet being used to limit the blade and the blade holder, combined with Figure 4 As shown.

[0023] Furthermore, the tool holder punching platform 4 includes a frame 401, a first conveying track 402 disposed on the top of the frame 401, the first conveying track 402 being composed of a frame, conveying rollers at both ends of the frame, and a transmission belt sleeved between the two conveying rollers; and a cutting table 404 disposed at the output end of the first conveying track 402, and a first pneumatic support 405 mounted on one side of the cutting table 404, which includes a support arm 4051 and a pneumatic module 4054, the pneumatic module 4054 being used to drive the support arm 4051 to move in the X and Y directions; and also includes a first magnetic suction manipulator 8 disposed at the end of the support arm 4051, the first magnetic suction manipulator 8 being used for the transfer of the tool holder.

[0024] Furthermore, the cutting platform 5 includes a base, a storage platform 501 and a second conveying track 505 mounted on the base, wherein the second conveying track 505 has the same structure as the first conveying track 402. A first support plate 502 is mounted on the storage platform 501, and a plurality of first pushing cylinders 503 are horizontally mounted on its side wall. A push plate 504 is fixed to the telescopic end of the plurality of first pushing cylinders 503.

[0025] The 3D vision robotic arm 9 used here is a mature existing technology. Its specific working principle is as follows:

[0026] Visual positioning: The 3D vision robot 9 locates the target object through a vision system. The vision system determines the object's specific location by scanning and recognizing the object's three-dimensional shape and position information.

[0027] Guided operation: After locating the target object, the vision system guides the robot arm to operate along a predetermined trajectory. This usually involves collecting point cloud data of the object, analyzing the object's features, and controlling the robot arm's movement through a software interface so that it can accurately grasp or manipulate the target object.

[0028] Hand-eye system: 3D vision robotic arms are typically equipped with a hand-eye system, including two types: a fixed imaging unit with the eye outside the hand and a servo imaging unit with the eye inside the hand. The eye-to-hand system has its visual imaging unit fixed externally to the robot, providing a global field of view, suitable for scenarios requiring a wide field of view. The eye-in-hand system has its imaging unit mounted at the end of the robotic arm, suitable for precise manipulation within a limited field of view.

[0029] Calibration process: In order to ensure that the robotic arm can accurately grasp or manipulate the target object, hand-eye calibration is required. The purpose of hand-eye calibration is to determine the relative positional relationship between the camera and the robotic arm. The calibration process includes initializing display parameters, three-dimensional coordinate system and calibration model, and using nonlinear optimization methods for calculation, so as to accurately complete the picking and placing process of the object.

[0030] Furthermore, the laser welding platform 6 includes a laser welding machine 601 and a welding end 602 at the end of the laser welding machine 601. The welding end 602 is placed above the support composite magnetic clamp 11 and aligned with the welding point of the blade holder and the blade.

[0031] Furthermore, the material feeding platform 7 includes a cabinet 701, wherein the cabinet 701 has a lifting platform that can pass through a slot opened at the top of the cabinet 701 and is used to stack several storage boxes 704; and several slots 705 equidistantly opened in each storage box 704 for arranging several products; it also includes a push frame 703 slidably installed on the upper surface of the cabinet 701, the push frame 703 surrounding the storage box 704 placed on the upper position; a third pneumatic support 702 provided on one side of the cabinet 701, which has the same structure as the first pneumatic support 405 and is provided with a second magnetic suction manipulator 10, the second magnetic suction manipulator 10 being used for product transfer; and a second support plate 706 provided on the side wall of the cabinet 701, and a second pushing cylinder 707 provided on the second support plate 706 is connected to the push frame 703 through a connecting block 708 provided at its telescopic end.

[0032] Combination Figure 1 , 2 As shown in Figure 4, the tool holder punching platform 4, the blade cutting platform 5, the laser welding platform 6, and the material discharge pushing platform 7 are arranged in a ring around the outer periphery of the intermittent transmission platform and are set sequentially along the running direction of the intermittent transmission platform.

[0033] The specific operating procedure is as follows:

[0034] The blade holders in this application are initially in a rolled state, and each blade holder is a semi-finished product with the middle part already bent. Figure 1 First, the blade holder is transported to the cutting table 404 via the first conveying track 402. Then, the punching process of adjacent blade holders is completed in conjunction with the punching device. Subsequently, the first pneumatic support 405 and the first magnetic suction manipulator 8 operate to transfer the punched single blade holder to the support composite magnetic clamp 11 where the intermittent transmission platform is located. Specifically, the blade holder placement area where the support composite magnetic clamp 11 is located is used to limit the blade holder. Then, the intermittent transmission platform drives the blade holder to move to the next station. At the same time, the previous station is run again, and so on, to achieve continuous work and improve work efficiency.

[0035] After reaching the blade cutting platform 5, combined with Figure 1 , 4The first push cylinder 503 extends and retracts, driving the push plate 504 to push the blade on the upper surface of the storage platform 501 to the surface of the second conveying track 505. Then, the second conveying track 505 transports the blade on it to the operating table 506 for cutting. After the cutting is completed, the second pneumatic support 507 drives the 3D vision robot 9 to run. The 3D vision robot 9 accurately places the cut blade into the blade placement area where the support composite magnetic clamp is located. The blade holder is adjacent to the blade placement area. When the blade and the blade holder are placed, the welding point at the connection between the two is exposed. Then, the gap separator 2 moves further, driving the blade and the blade holder into the welding station.

[0036] Subsequently, laser welding machine 601 was operated, combined with... Figure 1 , 2 As shown, the welding of the blade and blade holder is realized. The welded blade and blade holder are rotated to the next station by the turntable 3. It is worth noting that the blade and blade holder can be formed into a product after welding.

[0037] After arriving at the discharge push platform 7, combined with Figure 4 , 5 As shown, the second magnetic suction manipulator 10, combined with the third pneumatic support 702, removes the welded product from the composite magnetic clamp 11 and places it into the slot 705 on the storage box 704. It is known that the combination... Figure 5 The slots 705 are equidistantly spaced. When a certain number of products are placed, and the slots 705 on a single storage box 704 are full, the second push cylinder 707 uses the connecting block 708 and the push frame 703 as the transmission structure to push the storage box 704 full of products out of the work area.

[0038] Several push frames 703 are stacked on a lifting platform, which is a mature existing technology and preferably a cylinder. When the upper storage box 704 is pushed away, the lower storage box 704 can be pushed out by the lifting platform. Figure 5 At storage box 704, as shown, the product stacking operation continues.

[0039] Furthermore, this device employs the "RTO310.0 Real-time Control System," where each step is interconnected. This system is a mature existing technology and will not be described in detail here.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0041] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
