Description

Technical Field

[0001] This utility model relates to the field of welding machines, and more specifically, to a protective fiber laser welding machine for sensor welding. Background Technology

[0002] Fiber laser welding machines are precision welding devices that use fiber lasers as an energy source and are suitable for welding tiny, high-precision components such as sensors. However, traditional fiber laser welding machines can cause direct or reflected damage to the operator's retina during the welding process due to scattered laser light, and the molten metal splashes during welding, posing a significant safety hazard to the operator.

[0003] For example, the utility model patent (application number: 201720407502.5) discloses a "fiber laser welding machine," whose specification reveals that it includes a working platform, a tooling positioning device, and a welding mechanism. The workpiece is fixed on the tooling positioning device. The working platform is equipped with several X-axis slide rails, each of which has a tooling positioning device that can move back and forth. Above the working platform is a Z-axis crossbeam, on which is a vertical base that can move along the crossbeam direction. The vertical base has a welding mechanism that can move up and down. The working platform is equipped with a protective cover surrounding the welding area. The fiber laser welding machine also includes a PLC controller. Through XYZ axial movement, the welding mechanism can be transported to a designated position to perform staggered welding operations on workpieces on multiple tooling positioning devices, realizing continuous assembly line operation of a single welding machine. The protective cover can effectively isolate the operator from contact with the welding mechanism, protecting the operator's safety.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A protective fiber laser welding machine for sensor welding includes a body 1, which is specifically a fiber laser welding machine. The laser emission terminal in the body 1 is a processing head 11, which is located above the adjustment component 3. During welding, a high-power density laser is generated by the laser generator in the body 1. The laser is transmitted to the processing head 11 through an optical fiber. The laser beam is expanded by a collimating lens and contracted by a focusing lens to form a high-energy-density spot. The laser emitted from the processing head 11 falls between the two workpieces held by the adjustment component 3, causing the contact area between the two workpieces to melt and fuse together to complete the welding. The machine body 1 is equipped with a moving component 2. The top of the moving component 2 is equipped with an adjusting component 3, which is used to clamp the workpiece. The top of the adjusting component 3 is equipped with a clamping component 4. The clamping component 4 works in conjunction with the adjusting component 3 to provide another clamping method. The top of the clamping component 4 is equipped with two first protective parts. The outside of the adjusting component 3 is equipped with a flipping component 5, which is used to flip the second protective part downward to facilitate the placement or removal of the workpiece. The top of the flipping component 5 is equipped with two second protective parts. The first and second protective parts are used to prevent molten metal from splashing to the outside during welding. The inside of the flipping component 5 is equipped with a limiting component 6, which is used to keep the second protective plate 54 in an upright state.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the moving component 2 includes a processing table 21, which is used to connect with the adjusting component 3 and the flipping component 5. Two sliding seats 22 are provided at the front and rear of the bottom end of the processing table 21. The bottom ends of the two sliding seats 22 located on the same side are slidably provided with the same slide rail 23. By pushing the processing table 21, the sliding seats 22 slide on the slide rail 23, so that the processing table 21 moves linearly. The slide rail 23 is fixedly connected to the machine body 1.

[0023] Furthermore, such as Figure 2and Figure 3 As shown, the adjustment assembly 3 includes two slide rods 32, which restrict the movement of the moving block 33. Two fixed seats 31 are provided between the two slide rods 32, and the two fixed seats 31 are fixedly connected to the top of the processing table 21. A moving block 33 is provided on each side of the two fixed seats 31. The moving block 33 is used to contact the workpiece through the contact pad 36. The moving block 33 is slidably connected to the slide rods 32 on both sides. When the moving block 33 moves, it slides on the slide rods 32.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, the adjustment assembly 3 also includes two mounting rods 34. By rotating the mounting rods 34, the movement of the movable block 33 connected to the mounting rods 34 is controlled. The two mounting rods 34 are rotatably connected to opposite sides of the two movable blocks 33. By bringing the two movable blocks 33 closer to each other, the two workpieces in the middle are clamped, so that the contact surfaces between the two workpieces are tightly fitted. This is suitable for scenarios where the contact surface between the two workpieces is large. The end of the mounting rod 34 extends through the fixed seat 31 to opposite sides of the two fixed seats 31. The mounting rod 34 is threadedly connected to the fixed seat 31. When the mounting rod 34 is rotated, the movable block 33 and the mounting rod 34 are moved by the thread. The end of the mounting rod 34 is fixedly provided with a handle 35, which is used to facilitate the operator to grip and rotate the mounting rod 34.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the clamping assembly 4 includes a clamping plate 42 located at the top of the moving block 33. When two thin or cylindrical workpieces need to be laid flat for welding, the contact area between the two workpieces is small, and it is not suitable to clamp them in the middle by the two moving blocks 33. In this case, the clamping plate 42 can be pulled upward to place the workpiece between the clamping plate 42 and the moving block 33 for clamping. The two workpieces can be brought closer to each other and made to contact by rotating the mounting rod 34. The top of the movable block 33 has two connecting grooves 41. A connecting rod 43 is slidably installed inside the connecting groove 41. When the connecting rod 43 moves, it slides inside the connecting groove 41 to ensure the stability of the clamping plate 42 when it moves. A piston is fixedly installed at the bottom of the connecting rod 43. The piston is slidably connected to the inside of the connecting groove 41. When the clamping plate 42 is pulled, the piston reduces the air pressure inside the connecting groove 41, so that the resistance increases as the clamping plate 42 moves upward. When the clamping plate 42 is released, the piston will pull the connecting rod 43 back through the low pressure, so that the clamping plate 42 is reset. This allows the workpiece between the movable block 33 and the clamping plate 42 to be clamped. The top of the connecting rod 43 is fixedly connected to the clamping plate 42.

[0026] Furthermore, such as Figure 3As shown, each of the two moving blocks 33 has a contact element on its opposite side. The contact element is used to contact the workpiece that needs to be clamped. The contact element includes a contact pad 36 that is fixedly connected to the moving block 33. The contact pad 36 includes, but is not limited to, a rubber pad. The contact pad 36 contacts the workpiece, thereby avoiding scratches on the workpiece caused by clamping.

[0027] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the two first protective components are located on opposite sides of the two clamping plates 42. The first protective component includes a first protective plate 44 fixedly connected to the clamping plate 42, thereby increasing the protection range.

[0028] Example 2 The protective fiber laser welding machine for sensor welding provided in Example 1 has been further optimized, specifically, as follows: Figure 2 , Figure 3 and Figure 4 As shown, the flipping assembly 5 includes two mounting seats 51. The mounting seats 51 are used to connect with the limiting assembly 6. The two mounting seats 51 are located on both sides of the adjusting assembly 3. They are protected by two secondary protective parts above the mounting seats 51. The mounting seats 51 are fixedly connected to the top of the processing table 21. Two connecting blocks 52 are fixedly provided on the top of the mounting seats 51. A connecting seat 53 is rotatably provided between the two connecting blocks 52. The connecting seat 53 can move through the two connecting blocks 52. The connecting seat 53 is used to connect with the secondary protective parts.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the two secondary protective components include two secondary protective plates 54. The primary protective plate 44 and the secondary protective plate 54 include, but are not limited to, laser protective glass, which can prevent molten metal particles from splashing to the outside, block laser scattering and radiation, and allow the operator to observe the internal welding process. The two secondary protective plates 54 are fixed to the top of the connecting seat 53, and the connecting seat 53 can be moved by flipping the secondary protective plates 54.

[0030] Furthermore, such as Figure 3 and Figure 4 As shown, the limiting component 6 includes two limiting blocks 64 located at the top of the mounting base 51. The limiting blocks 64 are used to abut against the limiting groove 65 below the limiting seat 62, thereby limiting the limiting seat 62 and the second protective plate 54 to continue to flip by the elastic force of the spring 63. The two connecting blocks 52 located at the top of the mounting base 51 are each provided with a limiting seat 62 on opposite sides. The limiting seat 62 is fixedly connected to the second protective plate 54. Two limiting blocks 64 are located at the bottom ends of two limiting seats 62 respectively. Below the limiting blocks 64, there is a mounting groove 61 opened at the top of the mounting base 51. The mounting groove 61 is provided with a number of elastic elements, including springs 63. The two ends of the springs 63 are fixedly connected to the inside of the mounting groove 61 and the bottom end of the limiting blocks 64 respectively. The elastic force of the springs 63 causes the limiting blocks 64 to contact the inside of the limiting groove 65. The limiting blocks 64 are slidably connected to the inside of the mounting groove 61. The bottom end of the limiting seat 62 is provided with a limiting groove 65. The top end of the limiting blocks 64 is arc-shaped. The internal shape of the limiting groove 65 matches the top end of the limiting blocks 64. The top end of the limiting blocks 64 is in contact with the inside of the limiting groove 65.

[0031] The protective fiber laser welding machine for sensor welding provided by this utility model is used as follows: When two workpieces need to be welded together, the second protective plate 54 on one side is pushed down, causing the limiting groove 65 under the limiting seat 62 to disengage from the limiting block 64. The limiting seat 62 can then flip down normally. The workpiece is then placed between the two contact pads 36. The mounting rod 34 is then rotated, and through the threaded transmission between it and the fixed seat 31, the two moving blocks 33 are brought closer together. The contact pads 36 contact and clamp the workpieces, making the two workpieces in close contact. The contact position between the two workpieces is directly below the processing head 11. The flipped-down second protective plate 54 is then raised again. The limiting block 64 enters the limiting groove 65 through the elastic force of the spring 63 and holds it in place, preventing the second protective plate 54 from easily flipping. A high-power density laser is then generated by the laser generator in the machine body 1. The laser is transmitted to the processing head 11 through an optical fiber. A high-energy-density spot is formed by expanding the beam with a collimating lens and contracting the beam with a focusing lens. The processing head 11 emits the laser, melting and fusing the two contact positions together, thus completing the welding.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
