[0075] Then, the built-in power source on the frame 1 drives the material moving frame 21 to slide toward the finished product frame 23, and the material moving frame 21 stops sliding after moving to the predetermined position to release the substrate; then, the built-in telescopic power source of the frame 1 drives the two lifting plates 24 to slide downward respectively, until the substrate to be welded collides with the welding platform 11, and the welded substrate collides with the finished product frame 23 or the substrate placed on the finished product frame 23; the adsorption force between the lifting plate 24 and the substrate is removed to release the substrate; then the two lifting plates 24 slide upward and return to the standby state, waiting for the material moving operation on the next side; with the help of the material moving unit 2, the loading and unloading operations of the substrate are completed at the same time, thereby improving the working efficiency. The overall standby time of the equipment is reduced, and the time cost of the equipment is reduced.

[0076] Example 3, refer to Figure 1~Figure 3 and Figure 5 , which is the third embodiment of the present invention. On the basis of the first embodiment, this embodiment further adds an upper knife unit 3, which specifically includes a transmission shaft 31, a loading piece 32 and a guide rail 33; first, the stacked cutter heads are placed in the cutter storage space 14 in sequence, and the first cutter head is exposed at the bottom of the cutter storage space 14; when a cutter head is needed, the loading piece 32 is driven by the built-in power source of the frame 1 to slide toward the direction just below the cutter storage space 14, and the loading piece 32 is squeezed and contacted with the cutter head exposed below the cutter storage space 14, and the first cutter head is pushed toward the direction close to the welding platform 11 by means of the squeezing of the loading piece 32, thereby completing the loading operation of the cutter head; the third embodiment of the present invention, which is the third embodiment of the present invention, After a cutter head leaves the bottom of the cutter storage space 14, it slides along the guide rail 33 to prevent the first cutter head from shifting to the left or right.

After the loading part 32 pushes the first cutter head, it slides in the opposite direction to leave the bottom of the cutter storage space 14 and returns to the working state before cutting. It is located at the lower side of the cutter storage space 14 and waits for the next cutting operation. At the same time, the cutter heads stacked in the cutter storage space 14 slide downward along the cutter storage space 14 under the action of their own gravity. At this time, the second cutter head is exposed at the bottom of the cutter storage space 14 and waits for the next cutting operation. The automatic loading of a single cutter head is completed with the help of the cutting unit 3, which ensures the continuous progress of the welding operation and improves the overall operation efficiency.

[0077] Embodiment 4, referring to Figure 1 to Figure 9, which is the fourth embodiment of the present invention. On the basis of the third embodiment, this embodiment further adds a transfer unit 4, with the help of the transfer unit 4, the cutter head is transferred to the side of the substrate, which is convenient for the welding operation; the transfer unit 4 specifically includes a transfer frame 41, an intermediate frame 42, a transfer clamp 43 and a top block 44; when in use, after the feeder 32 pushes out the cutter head under the cutter storage space 14, an external force is applied to drive the transfer frame 41 to start rotating until the fixed cutter gap on the transfer frame 41 is just aligned with the cutter head at the guide rail 33, and the transfer frame 41 stops rotating; then external force is applied to drive the middle frame 42 to slide toward the guide rail 33, and the middle frame 42 slides synchronously with the transfer clamp 43 until the cutter head is squeezed and contacted with the top block 44, and the sliding of the middle frame 41 stops. At this time, the cutter head is just located in the fixed cutter gap; then external force is applied to drive the two transfer clamps 43 to approach each other, until the two transfer clamps 43 are squeezed and contacted with the upper and lower planes of the cutter head respectively, and the sliding of the transfer clamps 43 is stopped, and the fixation of the cutter head is completed; at this time, the material removal and fixation of the cutter head are completed.

With the help of the transfer unit 4, the smooth transportation of the cutter head is completed, and the consistency of the cutter head transportation is ensured; the force applied by the transfer clamp 43 on the cutter head provides stability support for the welding of the cutter head, which is conducive to improving the consistency of the saw blade welding effect.

[0079] Example 5, refer to Figure 1~Figure 2 , which is the fifth embodiment of the present invention. On the basis of the fourth embodiment, this embodiment further adds a welding stabilization unit 5, and the specific welding stabilization unit 5 includes a support block 51 and a pressure block 52; after the substrate is placed on the welding platform 11, an external force is applied to drive the pressure block 52 to slide downward until the pressure block 52 is in compression contact with the upper surface of the substrate. At this time, the pressure block 52 and the support block 51 are respectively located above and below the substrate. With the help of the extrusion force between the two, the stability of the substrate during welding is improved, and the vibration of the substrate during welding between the substrate and the cutter head is avoided, resulting in poor welding effect or even welding failure.

[0080] Example 6, refer to Figure 1 to Figure 9 , which is the sixth embodiment of the present invention. On the basis of the fourth embodiment, this embodiment further adds a transfer stabilization unit 6. The specific transfer stabilization unit 6 includes a swing arm 61, a stabilizing member 62, a sliding frame 63, a trigger member 64, an articulated seat 1 65, an articulated seat 2 66, a spring 1 67 and a spring 2 68. When in use, when the intermediate frame 42 slides toward the direction close to the clamping member 12, the cutter head at the guide rail 33 will first be squeezed and contacted with the trigger member 64; the cutter head squeezes the trigger member 64 close to the intermediate frame 42, and the trigger member 64 drives the sliding frame 63 to slide in the same direction, and the sliding frame 63 slides in the same direction. The movable frame 63 squeezes the spring 2 68, and the spring 2 68 contracts and accumulates elastic force under the force; when the sliding frame 63 slides, it will drive the spring 1 67 to extend through the rotating hinge seat 1 65, and the spring 1 67 extends and accumulates elastic force, and with the help of the elastic force generated by the spring 1 67, the hinge seat 2 66 is driven to gradually approach the hinge seat 1 65. At this time, the hinge seat 2 66 starts to rotate on the swing arm 61, and in the process of the hinge seat 2 66 approaching the hinge seat 1 65, it will move with the swing arm 61 and the fixing member 62 toward the side of the cutter head until the fixing member 62 is squeezed and contacted with the side of the cutter head.

[0081] The number of the transport stabilization units 6 is preferably two, and the two transport stabilization units 6 share a sliding frame 63 and a spring 68; the two stabilization members 62 squeeze the cutter head to improve the stability of the cutter head transport; the rotatable stabilization member 62 can reduce the friction between the cutter head and the stabilization member 62; at the same time, with the help of the shared sliding frame 63 and the spring 68, the force on the two sides of the cutter head is more balanced, ensuring the accuracy and consistency of the cutter head position, facilitating the welding of the cutter head and the base, avoiding deviations during the welding of the cutter head, and reducing the welding quality of the saw blade.

[0082] When the blade welding is completed, in the process of the intermediate frame 42 moving away from the base, the spring 2 68 gradually releases the accumulated elastic force, the sliding frame 63 and the trigger member 64 slide toward the direction close to the transfer clamp 43, and when the trigger member 64 is separated from the blade, the spring 2 68 returns to the natural extension state; the sliding frame 63 drives the hinge seat 1 65 to gradually approach the hinge seat 2 66 during the sliding process, and the state of the spring 1 67 changes, which is divided into two steps. The first step is from elongation to natural extension; the second step is from natural extension to shortening and then back to natural extension; the resetting operation of the transfer stabilization unit 6 is completed, and the next blade welding transfer is waiting.

[0083] Embodiment 7, refer to Figure 1 to Figure 12, which is the seventh embodiment of the present invention. On the basis of the third embodiment, this embodiment further adds a fine-tuning unit 7. The specific fine-tuning unit 7 includes a fine-tuning member 701, a spring three 702, an extrusion member 703, an adjustment member 704, a base member 705, a toothed belt 706, a gear one 707, a worm wheel 708, a worm 709, a gear two 710, a gear three 711, a swing frame 712, a ratchet structure 713 and a push rod 714; the ratchet structure 713 is a prior art and is not described here any more. A ratchet transmission structure that can realize unidirectional rotation in the prior art can be selected, and the rotation direction can be adjusted; the number of the fine-tuning units 7 is preferably two, which are respectively located on two sides of the two clamping members 12 away from each other.

[0084] When in use, several cutter heads of adjacent models will be divided into a group, and the produced cutter heads as a whole can be divided into several groups, and the size differences of the cutter heads within the group are relatively small; when producing cutter heads within the same group, the size of the cutter heads changes to a certain extent, resulting in an incomplete match between the cutter heads and the cutter storage space 14, that is, a shaking gap appears between the inner wall of the cutter storage space 14 and the cutter head, and the consistency of the placement of the cutter heads becomes worse. When cutting, the cutter heads are prone to tilt, causing welding failure between the cutter head and the substrate.

[0085] The loading member 32 starts to slide under the action of external force, and pushes out the cutter head exposed under the cutter storage space 14, completing the material picking and cutting operation of the cutter head; in the process of the loading member 32 pushing the cutter head away from the bottom of the cutter storage space 14, it will drive the push rod 714 to move synchronously, and the push rod 714 and the swing frame 712 will be squeezed and contacted. With the help of the squeezing of the push rod 714, the swing frame 712 first approaches on the adjustment member 704 and starts to rotate. When the swing frame 712 rotates, it drives the gear three 711 to rotate in the same direction through the ratchet structure 713, and the gear three 711 drives the gear two 710, the worm wheel 708, and the worm 709 in turn. , gear 707 rotates, and gear 707 drives the toothed belt 706 to slide downward when rotating. The toothed belt 706 drives the base member 705 and the extrusion member 703 to move synchronously. When the extrusion member 703 slides downward, it will be squeezed and contacted with the fine-tuning member 701, thereby causing the fine-tuning member 701 to slide in the direction of extending into the tool storage space 14 in the through hole 15; the two fine-tuning members 701 are close to each other, and the tool head is located in the middle of the two fine-tuning members 701. With the help of the sliding of the fine-tuning member 701, the distance between the two fine-tuning members 701 can be adjusted, thereby adjusting the model of the tool head that can be placed in the tool storage space 14.

[0086] The thickness of the extrusion 703 has various sizes and models, and the extrusion 703 with the same thickness can have various length sizes; by replacing the extrusion 703 with different thicknesses, different sizes of gaps can be created between the two fine-tuning parts 701 to meet the storage of different types of cutter heads in the same group; when the cutter head model involves changing groups, the positions of the clamping part 12 and the adjusting part 704 can be adjusted at the same time to make the gap between the two clamping parts 12 meet the types of cutter heads in different groups, thereby improving the overall applicability of the welding device and reducing the number of tooling.

[0087] When the cutter head model is switched, there are two switching states, the first is that the cutter head switches from a larger model to a smaller model; the second is that the cutter head switches from a smaller model to a larger model. The thickness of the extrusion member 703 on the base member 705 can be adjusted to achieve the application of cutter heads of different sizes; on this basis, if a certain model of cutter head is to be welded in large quantities, after selecting the corresponding extrusion member 703, an external force can be applied to the adjustment member 704 to slide in the direction away from the loading member 32, and the gear 1 707 is separated from the toothed belt 706; the push rod 714 and the swing frame 712 are always in a non-contact state, at this time, the distance between the two fine-tuning members 701 is fixed, which meets the storage requirements of the cutter head; when the cutter head needs to be changed, an external force is applied to drive the adjustment member 704 to slide in the direction close to the loading member 32, and the gear 1 707 is meshed and connected with the toothed belt 706, ready to adjust the position of the fine-tuning member 701.
