Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] Example 1, as Figure 1 and Figure 2 shown, a welding device for the production of semiconductor laser housings includes a cabinet 1, a circular outer shell 7 and a base 8. An observation door 2 is rotatably connected to the front end of the cabinet 1, a control panel 3 is fixedly installed at the front end of the cabinet 1, universal wheels 4 are fixedly connected to the four corners of the lower end of the cabinet 1, an adaptive welding assembly 5 is arranged on the inner surface of the cabinet 1, and a sealing test assembly 6 is arranged at the rear part of the inner surface of the cabinet 1.

[0034] In the process of implementing this embodiment, the circular outer shell 7 is sleeved on the adaptive welding assembly 5. During the sleeving process, the circular outer shell 7 will be automatically internally supported and fixed, and during the internal support process, the welding position will be automatically adjusted according to the size of the inner diameter of the circular outer shell 7. Subsequently, the base 8 is placed on the inner surface of the circular outer shell 7. By operating the control panel 3, the adaptive welding assembly 5 adjusts the position of the base 8 in height, so that the upper ends of the base 8 and the circular outer shell 7 are on the same horizontal plane. The adaptive welding assembly 5 performs laser welding operations on the connection between the circular outer shell 7 and the base 8. After the welding is completed, the sealing test assembly 6 detects the sealing performance of the welding.

[0035] The control panel 3 mentioned above is a mature control technology means and device in the prior art. In this solution, the functions that can be controlled are utilized, and its internal structure, principle, and connection method will not be elaborated further.

[0036] Specifically, in order to achieve adaptive laser welding for outer shells with different inner diameters, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, the adaptive welding assembly 5 includes a servo motor 51 fixedly connected to the inner surface of the lower part of the cabinet 1, an arc-shaped groove 56 is formed in the lower part of the inner surface of the upper cabinet 1, an arc-shaped block 57 is rotatably connected to the inner surface of the arc-shaped groove 56, a rotating ring 58 is rotatably connected to the inner surface of the arc-shaped block 57, an internal support mechanism 52 and an adjustment mechanism 54 are arranged at the lower part of the inner surface of the upper cabinet 1, and an adaptive mechanism 53 and a pressing mechanism 55 are arranged on the inner surface of the upper cabinet 1.

[0037] Further, refer to Figure 3 、 Figure 6 and Figure 7 In this embodiment, the internal support mechanism 52 includes a rotating rod 521 rotatably connected to the inner surface of the cabinet 1. The upper part of the outer surface of the rotating rod 521 is fixedly connected with sliding groove plates 522 annularly and equidistantly. Inner support plates 523 are slidably connected to the inner surfaces of the four sliding groove plates 522. Springs 524 fixedly connected to the inner support plates 523 are symmetrically fixed up and down on the inner surfaces of the four sliding groove plates 522. Arc-shaped inclined blocks 525 are fixedly connected to the upper ends of the four inner support plates 523. A one-way bearing 529 is fixedly connected to the inner surface of the rotating rod 521. The transmission rod connected to the output end of the servo motor 51 through a coupling is fixedly connected to the inner surface of the one-way bearing 529.

[0038] Further, refer to Figure 3 、 Figure 6 and Figure 7, in this embodiment, a number of ball bearings 526 are symmetrically arranged on the left and right on the inner surfaces of the four inner support plates 523, heating plates 527 are symmetrically and fixedly installed on the left and right on the inner surfaces of the four inner support plates 523, and rubber plates 528 are fixedly connected to the inner surfaces of the four inner support plates 523.

[0039] During the implementation process, place the lower end of the circular outer shell 7 on the outer surfaces of the four arc-shaped inclined blocks 525, and then press down the circular outer shell 7, so that the circular outer shell 7 can squeeze the four arc-shaped inclined blocks 525, and gradually squeeze the inner support plates 523 onto the inner surface of the circular outer shell 7. By the rolling of the ball bearings 526, the friction can be reduced, which is convenient for the fixation of the circular outer shell 7. At this time, the inner support plates 523 slide on the inner surface of the chute plate 522, so that the first spring 524 is in a compressed state. Continue to press the circular outer shell 7, so that the lower end of the circular outer shell 7 can closely adhere to the outer surface of the arc-shaped block 57. Under the compression reaction force of the first spring 524, the four inner support plates 523 can perform the inner support fixation operation on circular outer shells 7 of different sizes.

[0040] Secondly, the circular outer shell 7 can be heated by the heating plates 527, and the temperature of the circular outer shell 7 can be increased by heat transfer, reducing the thermal stress during the subsequent laser welding process. At the same time, the heating of the heating plates 527 will cause the rubber plates 528 to deform, so that the rubber plates 528 can closely adhere to the inner surface of the circular outer shell 7, increasing the friction between the inner support plates 523 and the circular outer shell 7, providing a prerequisite for the subsequent rotational welding of the circular outer shell 7, enabling the circular outer shell 7 to be stably fixed and reducing friction, ensuring the minimum deformation of the outer shell during the laser welding process. At the same time, by heating to increase the temperature, the thermal stress is reduced, and the friction between the outer shell and the inner support is enhanced, providing stable conditions for the subsequent welding, which helps to improve the welding quality and production efficiency.

[0041] There is a layer of rubber sheet on the outer surface of the above-mentioned arc-shaped block 57 during actual use.

[0042] The above-mentioned heating plates 527 are mature heating technical means and equipment in the prior art. In this solution, their heating function is utilized, and their internal structure, principle and connection method will not be elaborated.

[0043] Further, refer to Figure 3 and Figure 9, in this embodiment, the adjusting mechanism 54 includes a fixed rod 542 fixedly connected to the rear part of the inner surface of the cabinet 1. A bevel ring block 543 is rotatably connected to the inner surface of the fixed rod 542. A one-way bearing II 541 is fixedly connected to the outer surface of the transmission rod connected to the output end of the servo motor 51 through a coupling. A pulley group 544 is fixedly connected to the outer surfaces of the one-way bearing II 541 and the bevel ring block 543. A cylinder 549 is fixedly connected to the inner surface of the cabinet 1. A push rod 545 is slidably connected to the inner surface of the cylinder 549. A second spring 546 is sleeved on the outer surface of the push rod 545. Two ends of the second spring 546 are respectively fixedly connected to the inner surface of the cylinder 549 and the piston on the push rod 545. A fixed ring 547 rotatably connected to the rotating rod 521 is fixedly connected to the lower end of the circular groove ring 535. The fixed ring 547 is communicated with the inner surface of the cylinder 549 through a pipeline. A piston push plate 548 is slidably connected to the inner surface of the rotating rod 521.

[0044] During the implementation process, after the circular housing 7 is fixed, the base 8 is placed inside the circular housing 7, so that the lower end of the base 8 is closely attached to the upper end of the piston push plate 548. When it is necessary to align the upper end of the base 8 with the upper end of the circular housing 7, at this time, the output end of the servo motor 51 is driven to rotate reversely through the coupling, and the one-way bearing II 541 is in a locked state. The bevel ring block 543 is driven to rotate through the transmission of the pulley group 544, which will squeeze the push rod 545 to move upward. The second spring 546 is in a stretched state, and the cylinder 549 is pushed into the inner surface of the fixed ring 547 and enters the inner surface of the rotating rod 521 through the flow channel, pushing the piston push plate 548 to achieve a change in height, so that bases 8 with different thicknesses can always be on the same horizontal plane as the circular housing 7 under the adjustment, and the heating ring on the upper end of the piston push plate 548 can also be used to perform heating operations on it, reducing the thermal stress of laser welding.

[0045] Secondly, after the welding is completed, the welded housing can also be automatically ejected, which is convenient for taking the welded housing, so that bases 8 with different thicknesses are always on the same horizontal plane as the circular housing 7, thereby ensuring the stability and accuracy of the laser welding process. At the same time, the thermal stress is reduced through the heating process, improving the welding quality. After the welding is completed, the housing can also be automatically ejected, which is convenient for taking out the welded product, improving the production efficiency and operation convenience.

[0046] The above-mentioned pulley group 544 is composed of two pulleys and a belt.

[0047] Further, refer to Figure 3 and Figure 8, in this embodiment, the adaptive mechanism 53 includes a circular groove 531 formed in the inner surface of the arc-shaped inclined block 525. The inner surfaces of the four circular grooves 531 are all slidably connected to a first piston rod 532 fixedly connected to the inner support plate 523. The inner surfaces of the four circular grooves 531 penetrate and extend to the lower end of the arc-shaped inclined block 525 and are fixedly connected to a hard pipe 533. A circular ring 534 is fixedly connected to the outer surfaces of the four hard pipes 533. A circular groove ring 535 is rotatably connected to the outer surface of the circular ring 534. A hydraulic cylinder 536 is fixedly connected to the inner surface of the upper cabinet 1. A fixed plate 537 is fixedly connected to the lower end of the hydraulic cylinder 536. The inner surfaces of the left and right sides of the fixed plate 537 are symmetrically slidably connected to a second piston rod 538. Welding mechanisms 539 are fixedly installed at the lower ends of the two second piston rods 538. A connecting pipe 5310 penetrates and extends to the inner surface of the fixed plate 537 and is fixedly connected to the lower part of the inner surface of the circular groove ring 535.

[0048] During the implementation process, when the circular outer shell 7 is internally supported and fixed by the inner support plate 523, the inward contraction of the inner support plate 523 will push the first piston rod 532 to slide on the inner surface of the circular groove 531, so that the hydraulic oil in the inner cavity of the circular groove 531 enters the circular groove ring 535 through the hard pipe 533, and enters the inner cavity of the fixed plate 537 through the connecting pipe 5310 under the extrusion effect, pushing the welding mechanisms 539 on the two second piston rods 538 to move away from each other. When facing circular outer shells 7 of different sizes, during the process of fixing the circular outer shell 7, the welding mechanism 539 can automatically adjust the welding position according to the inner diameter size of the fixed circular outer shell 7, and the welding mechanism 539 is always directly above the welding position.

[0049] Secondly, start the hydraulic cylinder 536 to drive the fixed plate 537 to move downward, and drive the welding mechanism 539 to a suitable welding height to realize welding of circular outer shells 7 and bases 8 with different heights.

[0050] In addition, when it is necessary to weld the circular outer shell 7 and the base 8, at this time, start the output end of the servo motor 51 to drive the transmission rod to rotate forward through the coupling. Under the locking effect of the one-way bearing 529, the rotating rod 521 rotates, which can drive the circular outer shell 7 and the base 8 after internal support and fixation to rotate and cooperate with the welding mechanism 539 to perform laser welding on them. During the process of internally supporting and fixing circular outer shells 7 of different sizes, the welding mechanism 539 automatically adjusts the welding position in a linkage manner to adapt to the change of the inner diameter of the outer shell, so that the welding mechanism 539 can accurately adjust its position according to the different inner diameters of the outer shell, keeping the welding process in the best docking state all the time, improving the accuracy and stability of welding.

[0051] The above-mentioned welding mechanism 539 is a device commonly used in the prior art. In this solution, the function of welding by laser is utilized, and its internal structure, principle and connection method will not be elaborated.

[0052] The part of the connecting pipe 5310 connected to the cabinet 1 in the above is rigid, and the part connected to the fixing plate 537 is flexible.

[0053] The servo motor 51 in the above is a mature driving technical means and device in the prior art. In this solution, it can rotate forward and backward through a coupling at the output end, and can stop in time after rotating a set number of turns. The internal structure, principle and connection method thereof will not be elaborated.

[0054] Further, referring to Figure 3 and Figure 10 In this embodiment, the pressing mechanism 55 includes a round hole plate 551 fixedly connected to the lower end of the fixing plate 537. A round rod concave plate 552 is slidably connected to the inner surface of the round hole plate 551. A plurality of rollers 553 are rotatably connected to the round rod concave plate 552. Four spring threes 554 are sleeved on the outer surface of the round rod concave plate 552. The two ends of the four spring threes 554 are fixedly connected to the lower end of the fixing plate 537 and the upper end of the round rod concave plate 552 respectively.

[0055] During the implementation process, when the hydraulic cylinder 536 drives the fixing plate 537 to adjust the height of the welding mechanism 539, the rollers 553 on the round rod concave plate 552 will contact the upper ends of the circular shell 7 and the base 8 in advance, so that the rollers 553 will press down the circular shell 7 and the base 8, and the spring three 554 is in a compressed state. On the one hand, the upper end of the circular shell 7 and the base 8 can be adjusted to be on the same horizontal plane. On the other hand, the lower end of the circular shell 7 can be tightly pressed on the rubber sheet on the outer surface of the arc-shaped block 57.

[0056] Embodiment 2. On the basis of Embodiment 1, this embodiment adds a sealing test component 6 for testing the sealing performance of the circular shell 7 and the base 8 after laser welding, so as to achieve the purpose of testing the sealing performance of the circular shell 7 and the base 8 after laser welding.

[0057] Specifically, in order to test the sealing performance of the circular shell 7 and the base 8 after laser welding, referring to Figure 3 、 Figure 4 and Figure 11 In this embodiment, the sealing test component 6 includes a round cover 61 fixedly connected to the rear part of the inner surface of the cabinet 1. A blowing mechanism 62 is arranged on the inner surface of the round cover 61. A testing mechanism 63 is arranged on the upper part of the inner surface of the cabinet 1.

[0058] Further, referring to Figure 3 and Figure 11, in this embodiment, the blowing mechanism 62 includes a first round rod 621 rotatably connected to the round cover 61. A third one-way bearing 623 is fixedly connected to the outer surface of the first round rod 621. A transmission mechanism 624 is fixedly connected to the outer surfaces of the third one-way bearing 623 and the hydraulic cylinder 536. The front end of the first round rod 621 is fixedly connected to a gearbox 622 fixedly connected to the inner surface of the round cover 61. The front end of the gearbox 622 is fixedly connected to a second round rod 625 rotatably connected to the round cover 61. A fan blade 626 is fixedly connected to the outer surface of the second round rod 625. A connecting pipe 627 penetrates through the left part of the inner surface of the round cover 61 and extends to be fixedly connected to the upper end of the rotating ring 58.

[0059] Further, referring to Figure 4 , in this embodiment, the testing mechanism 63 includes a connecting plate 631 fixedly connected to the upper part of the inner surface of the cabinet 1, and fluff 632 is fixedly connected to the lower end of the connecting plate 631.

[0060] During the implementation process, when the hydraulic cylinder 536 moves downward for the welding movement, it will be transmitted through the transmission mechanism 624. However, under the action of the third one-way bearing 623, the first round rod 621 will not rotate. After the laser welding is completed, when the hydraulic cylinder 536 moves upward, it will be transmitted through the transmission mechanism 624 and locked by the third one-way bearing 623 to drive the first round rod 621 to rotate. Under the speed-changing effect of the gearbox 622, the fan blade 626 on the second round rod 625 will rotate rapidly to suck the air outside the cabinet 1 through the connecting pipe 627 into the arc-shaped block 57 and then into the welded shell. When there is a gap in the welding, the wind will move upward through the gap and blow the fluff 632 on the connecting plate 631. When there is no gap, the fluff 632 will not move, and the un-welded position can be judged by the position of the fluff 632. After the laser welding is completed, the external air can be quickly sucked in by the fan, and the welding gap can be detected by using the air flow, so as to judge whether the welding is complete. Whether there are defects in the welding can be judged by the movement of the fluff 632, which improves the accuracy of welding quality detection. At the same time, the application of the air flow helps to clean and cool after welding, improving production efficiency and welding accuracy.

In this solution, their function of being able to rotate in one direction and be locked in the other direction is utilized. In this solution, the locking directions of the first one-way bearing 529 and the second one-way bearing 541 are opposite, and their internal structures, principles and connection methods will not be elaborated further.

[0062] The above-mentioned gearbox 622 is a mature speed-changing technical means and equipment in the prior art. In this solution, its function of being able to change speed is utilized, and its internal structure, principle and connection method will not be elaborated further.

[0063] The transmission mechanism 624 described above is composed of a gear and a rack.

[0064] Working process: During use, the inner support mechanism 52 is used to perform the inner support and fixation operation on circular shells 7 of different sizes. During the inner support and fixation process, the linkage and adaptive mechanism 53 will automatically adjust the welding position according to the size of the circular shell 7. Subsequently, the adjustment mechanism 54 is used to adjust the height of the base 8 with different thicknesses, so that the upper ends of the base 8 and the circular shell 7 are on the same horizontal plane. Laser welding is performed through the adaptive mechanism 53. After the welding is completed, the blowing mechanism 62 and the testing mechanism 63 are used to detect whether the welding is sealed.
