Description

Technical Field

[0001] The embodiments of this utility model relate to the field of welding equipment technology, specifically to a laser welding device for saw blades. Background Technology

[0002] A saw blade typically consists of a base and a cutting head, with the cutting head welded to the outer edge of the circular base, as shown in the example below. Figure 12 As shown, the current process of welding the substrate and the cutting head is as follows: the gripper automatically aligns a cutting head with the outer edge of the circular substrate and locks their relative positions. Then, a laser welding machine is used to laser weld the joint between the cutting head and the substrate. This process is repeated to weld a ring of cutting heads onto the substrate, forming a saw blade.

[0003] However, the above method has the following drawbacks in actual operation: the circular substrate is generally placed horizontally, and the corresponding cutter head that is transferred by the gripper and comes into contact with the outer edge of the substrate should also be horizontal to facilitate welding. However, during the feeding process, the automatically moving gripper is not convenient to directly pick up the horizontal cutter head regardless of its posture, and may also block part of the joint, affecting welding. Production efficiency needs to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a saw blade laser welding equipment, which solves the technical problem in related technologies where the automatically moving grippers are inconvenient to directly grip the horizontal blade head and make it directly dock with the horizontal substrate when the saw blade laser welding equipment is feeding material, thus affecting production efficiency.

[0005] According to one aspect, at least one embodiment of the present invention provides a saw blade laser welding device, comprising: The frame is provided with a support platform for horizontally supporting the base and a tool storage station for storing the tool head, the tool storage station having a tool storage groove arranged vertically; The gripper arm is oscillating on the frame and is used to grip the blade head in the blade storage slot. After the gripper arm oscillates, it can drive the blade head to be horizontally aligned with the outer edge of the substrate. A welding component is disposed on the frame and located above the support platform. The welding component is used to weld the cutting head to the outer edge of the base.

[0006] For example, at least one embodiment of this utility model provides a saw blade laser welding device, wherein the support platform is a rotating component, the support platform rotation axis is arranged vertically, the gripper arm swing axis is arranged horizontally, the gripper arm is located on one side of the support platform, and the tool storage station is located below the gripper arm, so that after the gripper arm swings 90°, the tool head is directly connected to the outer edge of the substrate in a horizontal state.

[0007] For example, at least one embodiment of this utility model provides a saw blade laser welding device, wherein the gripper arm includes: A support frame, which is swayably mounted on the frame; The gripper is slidably mounted on the support frame, and its position for gripping the cutter head can be adjusted after sliding.

[0008] For example, at least one embodiment of this utility model provides a saw blade laser welding device, wherein a movable frame is slidably provided on the frame, and a plurality of tool storage stations are provided on the movable frame at intervals along the moving direction of the movable frame. The moving path of the movable frame passes through the swing path of the gripper arm, so that the gripper arm can grip the tool head in the tool storage slot.

[0009] For example, at least one embodiment of this utility model provides a saw blade laser welding device, wherein the blade storage groove has a blade inlet at at least one end, the frame is further provided with a feeding channel for storing a plurality of blade heads, one end of the feeding channel has a blade supply port, and after the movable frame moves, the blade supply port can communicate with any of the blade inlets, and further includes: The pusher is slidably mounted on the frame and located on one side of the feeding channel. After sliding, the pusher can push the cutter head at the inner end of the feeding channel through the feed port and the inlet port to the storage slot.

[0010] For example, at least one embodiment of the present invention provides a saw blade laser welding device, which further includes a centering component for adjusting the position of the cutter head in the tool storage groove. The centering component is disposed on the frame and located above the movable frame. The centering component includes: Two centering sections are slidably mounted on the frame. After sliding, the centering sections can abut against and push one end of the cutter head so that the cutter head is in the center position of the cutter storage slot.

[0011] For example, at least one embodiment of the present invention provides a saw blade laser welding device, wherein the frame is further provided with a clamping part for fixing the welding position of the blade head, and the clamping part is located between the support platform and the support frame; The clamping blade portion has a clearance hole for the clamping claw portion to pass through.

[0012] For example, at least one embodiment of this utility model provides a laser welding device for saw blades, wherein a pressure head is oscillating on the frame, the pressure head is located above the support platform, and the pressure head can press against the upper surface of the substrate after oscillating.

[0013] For example, at least one embodiment of this utility model provides a laser welding device for saw blades, wherein the frame is further provided with a protective air tube body, and the opening of the protective air tube body can face the joint between the base and the blade head.

[0014] For example, at least one embodiment of this utility model provides a laser welding device for saw blades, wherein the welded part is a three-axis welding device.

[0015] The beneficial effects of the embodiments of this utility model are as follows: The optimized tool head storage posture facilitates gripping by the gripper, allowing the tool heads to be stored vertically in the tool storage slot at the tool storage station. Vertical storage avoids the space limitations of horizontal placement, and the gripper arm can easily reach into the tool storage slot from the side or top to grip the tool heads, solving the problem of grippers being unable to directly grip horizontal tool heads. In addition, the core function of the gripper arm is to connect the vertically stored tool head to the horizontal substrate. Therefore, after the tool head is taken out, it can be directly driven by swinging to convert the vertically positioned tool head to a horizontal state, so that it can be directly connected to the outer edge of the horizontally supported substrate without additional position adjustment, quickly adapting to the substrate connection requirements.

[0016] The gripper arm is only responsible for gripping and changing the posture of the cutter head. After docking, it can be removed or its position adjusted. The welding part is independently set above the support platform and is specifically responsible for welding the joint between the cutter head and the base body. This avoids spatial conflicts between the gripper and the welding operation, ensures that the welding process is not disturbed, and thus improves the overall production efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0021] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figure 1 As shown, this invention illustrates a saw blade laser welding device according to one embodiment. The frame 1 serves as the basic support component of the entire device, used to install and fix other components, such as the support platform 2, the tool storage station 3, the gripper arm 4, and the welding parts 5, all mounted on the frame 1, providing a stable installation foundation and working platform for these components. The support platform 2 is assembled on the frame 1 to horizontally support the substrate A, ensuring that the substrate A remains stable and horizontal during the welding process, facilitating the subsequent docking and welding of the blade head B. Specifically, the support platform 2 can be a vertical cylinder with the diameter progressively increasing from top to bottom, allowing the sheet-like substrate A to fit through its central through-hole onto the top-smaller diameter vertical cylinder. Preferably, the support platform 2 is a rotating component because the outer edges of the sheet-like substrate A need to be welded to the blade head B. After completing a set of blade head B welding operations, the rotation of the support platform 2 facilitates the gripper arm 4 to dock the blade head B horizontally with the free outer edge of the sheet-like substrate A.

[0027] Preferably, the tool storage station 3 mounted on the frame 1 has a vertically arranged tool storage groove 301, and the top of the tool storage groove 301 has a tool retrieval opening. If the vertical tool head B is directly aligned with the outer edge of the sheet substrate A in a horizontal state by relying solely on the swing of the gripper arm 4, then the tool storage station 3 should be located below one side of the support platform 2, and the gripper arm 4 should be installed at the same height as the support platform 2 and close to the tool storage station 3. The gripper arm 4 can swing 90 degrees from bottom to top. This can avoid the problem of inconvenience in gripping the tool head B when it is placed horizontally, and the structural requirements of the gripper arm 4 are lower, and it does not need to have a high multi-axis flipping function, thus reducing costs.

[0028] Further consideration could be given to the gripper arm 4, which possesses a certain multi-axis rotation capability to adjust the angle of the gripper head B. After conveniently gripping the vertical gripper head B, it can also swing directly and utilize its multi-axis rotation function to mate the gripper head B with the outer edge of the sheet-like substrate A at any height and angle, without requiring excessive restrictions on the position of each component. Specifically, the gripper arm 4 first grips the gripper head B, then uses a rotation action to convert the vertical gripper head B to a horizontal state, and then moves it to mate with the substrate A. The tool storage slot 301 can be set to be tilted at a certain angle, rather than being completely vertical, as long as it is convenient for the gripper arm 4 to grip and can convert the gripper head B to a horizontal state to mate with the substrate A through subsequent actions (the tool storage station 3 can be designed as a multi-layer tool storage slot 301 structure to increase the storage capacity of the gripper head B, reduce the number of loading times, and improve production efficiency). The above two forms can be selected according to the actual scenario. For scenarios with limited space, the solution with lower requirements for the gripper arm 4 structure will generally be used; otherwise, the other solution will be selected.

[0029] After the docking is completed, the laser welding component 5 installed on the support platform 2 can be started to weld the joint between the base A and the blade B. Preferably, the welding component 5 is a triaxial laser welding device because the joint is usually non-linear and the accuracy of the welding path is required to complete the operation of welding the blade B to the outer edge of the base A to form the finished saw blade.

[0030] like Figures 2-4 As shown, the preferred solution has lower requirements for the structure of the gripper arm 4 because most site spaces are limited, and it can also save some costs on the gripper arm 4. The requirements for its multi-axis flipping function are lower. Specifically, the support platform 2 is set vertically along its rotating axis, the gripper arm 4 is set horizontally along its swing axis, the gripper arm 4 is at the same height as the support platform 2 and is located on one side of the support platform 2, and the tool storage station 3 is located below the gripper arm 4.

[0031] Furthermore, the gripper arm 4 consists of a support frame 401 and a gripper part 402 that slides on it, which can satisfy the basic gripping and swinging functions. Therefore, the support frame 401, as the base, can be swung on the machine frame 1 by a rotary table, while the gripper part 402 used to grip the cutter head B can be slidably mounted on the support frame 401 by a linear cylinder or the like, to ensure that it has a certain gripping flexibility. After sliding, it can adjust the position of gripping the cutter head B and the position of docking with the outer edge of the base A to adapt to different scenario requirements.

[0032] Regarding the design of tool storage station 3, such as Figures 5-7 As shown, a corresponding form can also be adopted by moving the movable frame 6. Specifically, the movable frame 6 is slidably provided on the frame 1 via a screw or cylinder. Several tool storage stations 3 with a tool storage slot 301 are arranged at intervals along the moving direction on the movable frame 6. The moving path of the movable frame 6 passes through the swing path of the gripper arm 4. On the one hand, it is convenient for the gripper arm 4 to grip the tool head B in different tool storage slots 301. The larger interval makes it less prone to misoperation, and the displacement of the movable frame 6 can be precisely controlled. On the other hand, the movement of the movable frame 6 facilitates the realization of automated feeding function with the feeding channel 101. Specifically, the tool storage slot 301 has a tool inlet 302 at one or both ends. On the side of the frame 1 corresponding to the tool inlet 302, a feeding channel 101 for storing several tool heads B is arranged. The length direction of the feeding channel 101 is consistent with the moving direction of the movable frame 6, and a tool supply port 102 corresponding to the tool inlet 302 is opened at one end of it.

[0033] Cutting process: After the moving frame 6 moves, the cutting port 102 connects with any cutting port 302. The cutting pusher 7, which is slidably mounted on the frame 1 and located on the side of the feeding channel 101 opposite to the moving frame 6, begins to function. The movement of the cutting pusher 7 pushes the cutting head B at the inner end of the feeding channel 101 through the cutting port 102 and the cutting port 302 to the corresponding cutting slot 301. This cycle is repeated to evenly distribute several cutting heads B in the feeding channel 101 within the moving frame 6 for the gripper. Arm 4 clamps the blades without interfering with the welding process and enables automatic feeding, improving production efficiency. Different sizes of blade heads B can be arranged in the feeding channels 101 on both sides to adapt to different needs for blade heads B and produce complex saw blades. In addition, the shape of the pusher part 7 is basically the same as that of the vertical blade head B, and it can only push one side of the blade head B to avoid pushing multiple blade heads B at the same time. The width of the cutting edge 102 and the inlet 302 is slightly greater than or equal to the width of the vertically arranged blade head B to precisely control the number of blade heads B arranged.

[0034] Furthermore, given that the gripper arm 4 only has swing and telescopic gripping functions, the addition of the automatic feeding function may prevent the precise control of the gripper 402's gripping position through the movement of the pusher 7. This could affect the position of the cutter head B on the base A, causing parameters such as saw blade strength to fail to meet requirements. Therefore, to improve the positional accuracy of the cutter head B within the tool storage slot 301 and ensure gripping accuracy and saw blade quality, a centering component 8 for adjusting the position of the cutter head B within the tool storage slot 301 is installed on the frame 1. Figures 2-4 As shown, it is located above the moving frame 6 and is achieved using two symmetrical centering parts 801 that slide along the length of the tool storage groove 301. The driving mechanism can be a cylinder or pneumatic system. After the centering part 801 slides, it abuts against and pushes one end of the tool head B, so that the tool head B is in the center position of the tool storage groove 301, thus unifying the gripper part 402's position for gripping the tool head B. The centering part 801 can be an arc-shaped component, such as... Figure 3 As shown, only one end can act on the cutter head B to prevent interference between other parts and other components.

[0035] To ensure the stability of each component during welding and prevent displacement of the base A or the cutting head B, a clamping part 9 for fixing the welding position of the cutting head B is installed on the upright plate of the frame 1 between the support platform 2 and the support frame 401. Figures 8-11 As shown, the clamping part 9 can be composed of two swinging clamping arms, one above the other. After the clamping jaw 402 feeds the cutter head B, the upper and lower clamping arms swing to clamp the cutter head B. The clamping jaw 402 then retracts normally, and the swinging resets to allow for the next round of clamping the cutter head B. Furthermore, to prevent the upper and lower clamping arms from clamping the clamping jaw 402, or even its sliding structure, thus preventing subsequent cyclic operations, a clearance hole 901 is provided on the clamping part 9 for the clamping jaw 402 to pass through. Figure 10 As shown, the gripper 402 can pass through freely and can also properly fix the position of the cutter head B; as Figure 9 As shown, a swingable pressure head 10 is also installed on the vertical plate of the frame 1 between the support platform 2 and the support frame 401. After the pressure head 10 swings, it can press against the upper surface of the base A from above the support platform 2 to fix the position of the base A during the welding process.

[0036] like Figure 2 , Figure 4 As shown, a protective gas pipe 11 for conveying inert gas is also provided on the frame 1, so that its port can face the joint between the base A and the cutting head B, thereby further improving the welding quality.

[0037] Overall workflow: Before starting the equipment, the initial preparation of the substrate A and the cutting head B must be completed. The substrate A is placed horizontally on the support platform 2 of the frame 1. The support platform 2 rotates to adjust the substrate A to a suitable position. The pressure head 10 above swings and presses against the upper surface of the substrate A to ensure that the substrate A remains stable during welding.

[0038] Loading: The moving frame 6 moves multiple tool storage stations 3, aligning the tool inlet 302 of the tool storage slot 301 with the tool supply inlet 102 of the loading channel 101. The pusher 7 pushes the tool head B in the loading channel 101 into the tool storage slot 301. Then, the two centering parts 801 of the centering part 8 slide and push the tool head B, placing it in the center position of the tool storage slot 301, providing precise positioning for subsequent clamping.

[0039] Clamping and Transfer: The gripper arm 4 swings to the tool storage position 3, the gripper part 402 extends to clamp the vertical blade B, then swings 90 degrees to a horizontal position. At the same time, the gripper part 402 slides along the support frame 401 to adjust its position so that the blade B is precisely aligned with the outer edge of the base A. After that, the tool clamping part 9 clamps the blade B to fix its welding position, and the gripper arm 4 retracts to avoid obstructing the joint. At this time, the triaxial welding component 5 above the support platform 2 starts to perform laser welding on the joint between the blade B and the base A. At the same time, the protective gas tube 11 sprays protective gas onto the joint to improve the welding quality. This cycle continues until a circle of blades B is welded around the outer edge of the base A, forming a complete saw blade.
