The loading port 204 is arranged at the bottom end of the loading bin 201, and a plurality of blade heads 5 are arranged in the loading bin 201.

[0034] The blade positioning structure 3 includes a positioning plug 301. Two positioning plugs 301 are arranged on both sides below the loading port 204, and the two positioning plugs 301 are adapted to two adjacent saw blade grooves 401. Here, the positioning plug 301 is adapted to the saw blade groove 401, which means that the positioning plug 301 can be inserted into the saw blade groove 401, and after the positioning plug 301 is inserted, it can only move back along the original direction of insertion;

[0035] When in use, the saw blade 4 is placed on the rotary drive structure 103, and the six-axis robot 104 drives the loading bin 201 to move onto the saw blade 4. The loading bin 201 drives the positioning block 301 to move until the positioning block 301 is inserted into the saw blade groove 401. The position of the cutter head 5 is determined, and then the first cylinder 202 pushes the first push plate 203. The first push plate 203 pushes the cutter head 5 through the loading port 204 of the loading bin 201 and moves to the saw blade 4. Then the six-axis robot 104 drives the blade loading structure 2 to reset, and the three-axis drive structure 101 drives the welding equipment 102 to weld the saw blade 4 and the cutter head 5. After welding is completed, the rotary drive structure 103 drives the saw blade 4 to rotate to the next cutter head 5 welding position for the next round of welding work.

[0036] The present invention provides a positioning block 301 adapted to the saw blade groove 401 on the saw blade 4, and can match the notch position of the saw blade 4 through the positioning block 301 before placing the cutter head 5, so that the cutter head 5 can be exactly located at the welding position of the saw blade 4. The present invention can avoid errors in the placement of the cutter head 6 through a mechanical positioning structure, replace the traditional complex visual system solution, simplify the complexity of the equipment, and reduce the cost and operation difficulty.

[0037] Embodiment 2, as Figures 3 to 8 As shown, the blade feeding structure 2 also includes a blade pre-storage structure 205 and an installation box 206, and the installation box 206 is installed on the feeding bin 201;

[0041] When in use, the cutter head 5 pushed by the first push plate 203 enters the loading port 204 of the loading bin 201 and is stopped by the stop rod 205a. At the same time, the second cylinder 205h drives the second push plate 205i to move, so that the second push plate 205i and the first push plate 203 are located at the same horizontal plane, blocking the subsequent cutter head 5, so that a pre-storage place for the cutter head 5 is formed between the second push plate 205i and the stop rod 205a, and the cutter head 5 is pre-stored;

[0042] When the positioning block 301 is successfully positioned, the gear rod 205e comes into contact with the concave groove surface of the rotary drive structure 103 as the positioning block 301 is inserted. The gear rod 205e under pressure slides along the connecting rod 205f, driving the spring 205g to contract, thereby pushing the gear 205d to rotate. The gear 205d drives the toggle plate 205b to rotate through the rotating shaft 205c. The toggle plate 205b rotates from the convex arc surface 205k side toward the baffle rod 205a to the concave arc surface 205l side toward the baffle rod 205a, so that the baffle rod 205a is no longer limited by the toggle plate 205b. The second cylinder 205h drives the second push plate 205i to open. The second push plate 205i presses the cutter head 5 to move downward. The cutter head 5 squeezes the baffle rod 205a after it is no longer restricted, and is discharged from the loading port 204 and pressed onto the saw blade 4.

[0043] The present invention can automatically pre-store the blade in the loading bin 201 before positioning with the saw blade 4 by setting the blade pre-storage structure 205, and in the process of the positioning plug 301 being positioned and inserted into the saw blade slot 401, the rotary drive structure 103 cooperates with the toothed rod 205e to automatically open, and the second cylinder 205h and the second push plate 205i press the cutter head 5 onto the saw blade 4. The present invention can automatically discharge the blade after positioning is completed, and press the cutter head 5, so as to prevent the cutter head 5 from deviating and shaking during the discharge process, thereby affecting the accuracy.

[0045] Furthermore, a slide groove 302h is provided at the bottom end of the positioning bin 302a, and the connecting shaft 302g is slidably connected in the slide groove 302h;

[0046] When in use, according to the different numbers of saw blade slots 401 of the saw blade 4 to be processed, the micro cylinder 302d is turned on, the micro cylinder 302d pushes the slide plate 302e to move on the slide rail 302b, the slide plate 302e drives the micro motor 302f and the connecting shaft 302g to move, the connecting shaft 302g drives the positioning block 301 to move horizontally, so that one end of the positioning block 301 is adapted to one end of the saw blade slot 401 after the position is changed; then the micro motor 302f is turned on, the micro motor 302f drives the connecting shaft 302g to rotate, the connecting shaft 302g drives one end of the positioning block 301 to rotate, thereby driving the other end of the positioning block 301 to adapt to the other end of the saw blade slot 401 after the position is changed, so that the positioning block 301 is adapted to the saw blade slot 401 after the position is changed to complete the positioning work;
