[0046] Figures 1 to 5An optical device repair soldering apparatus provided in this application includes:

[0047] Mounting base 1 has multiple mounting holes 11 along its length for accommodating optical devices 100.

[0048] In this application, the mounting base 1 constitutes the basic support structure of the device. It has a plurality of mounting holes 11 evenly provided along its length. The shape and size of each mounting hole 11 are adapted to the body of the optical device 100 to be repaired and soldered, and are used to accommodate and initially position the optical device 100 during operation.

[0049] By adopting a layout design with multiple mounting holes 11, this device can achieve batch loading of optical devices 100, laying the foundation for subsequent batch welding operations and effectively improving the workpiece processing capacity and overall production efficiency per unit time.

[0050] The fixing base 2 is detachably disposed above the mounting base 1. The fixing base 2 has a plurality of downwardly extending L-shaped fixing plates 21 on the side facing the mounting base 1. Each pair of adjacent fixing plates 21 corresponds to a mounting hole 11 and is used to clamp and fix an optical device 100 housed in the mounting hole 11.

[0051] In this application, the mounting base 2 is detachably mounted above the mounting base 1 using a method such as screws or locating pins. Multiple downwardly extending L-shaped mounting plates 21 are fixedly mounted on the side facing the mounting base 1. These L-shaped mounting plates 21 are arranged such that every two adjacent mounting plates 21 correspond precisely to the position above a mounting hole 11.

[0052] When the mounting base 2 is installed in place, each pair of adjacent L-shaped mounting plates 21 can work together from both sides to stably hold the optical device 100 housed in the corresponding mounting hole 11, thereby preventing it from shifting or shaking during the welding process.

[0053] The detachable connection facilitates the installation, debugging, and maintenance of the mounting base 2. The clamping design of the L-shaped mounting plate 21 ensures the positional accuracy and stability of the optical device 100 at the welding station, providing the necessary conditions for ensuring consistent welding quality.

[0054] The first driving unit 3 is connected to the mounting base 1 for driving the mounting base 1 to move stepwise along a horizontal path so as to deliver each optical device 100 to the welding station in sequence.

[0055] In this application, the first drive unit 3 (which may be a stepper motor or a servo motor in conjunction with a linear guide mechanism) is connected to the mounting base 1 via a transmission mechanism. Its function is to drive the mounting base 1 to perform precise intermittent stepping movements along a preset horizontal path.

[0056] By programmatically controlling the movement distance of each step, this unit can sequentially and accurately transport each optical device 100 carried on the mounting base 1 to the designated welding station, thus achieving automated material feeding.

[0057] This design replaces traditional manual handling and positioning, which not only significantly improves the accuracy and efficiency of the feeding process, but also ensures that each optical device 100 can arrive at the welding point in a repeatable and accurate position, creating stable and reliable conditions for subsequent automated welding.

[0058] There are two welding stations, located on both sides of the moving path of the mounting base 1, and each welding station is equipped with at least two welding torches 4.

[0059] This device has two welding stations, which are symmetrically distributed on both sides of the horizontal movement path of the mounting base 1. Each welding station is equipped with at least two independent welding torches 4.

[0060] When the mounting base 1 carrying the optical device 100 steps to the welding station, multiple welding guns 4 at the station can be activated simultaneously. This layout supports simultaneous welding of different solder joints on the circumference of a single optical device 100, or parallel operation of multiple optical devices 100 at the same station, thereby significantly shortening the re-welding cycle of a single optical device 100 and significantly improving overall work efficiency.

[0061] The second drive unit 5 is connected to the welding torch 4 for driving the welding torch 4 to rotate around its axis during welding, so as to perform circumferential welding on the optical device 100.

[0062] In this application, the second drive unit 5 (e.g., a micro rotary motor) is connected to the welding torch 4 via a transmission. It is activated during the welding process, driving the welding torch 4 to rotate at a constant speed or in a programmable manner around its own axis.

[0063] The rotating welding torch 4 can perform circumferential welding on the part of the optical device 100 to be repaired (the annular gap between the body 101 and TO102), ensuring that the solder is evenly distributed in the circumference and effectively avoiding defects such as cold solder joints, missing solder joints or insufficient welding that may occur due to a fixed welding angle.

[0064] This circumferential welding method not only improves welding reliability but also helps to evenly distribute welding heat, reducing the risk of damaging internal components of the optical device 100 due to local overheating.

[0065] It is understood that the optical device repair welding device provided in this application achieves batch clamping and positioning of optical devices 100 through the cooperation of mounting base 1 and fixing base 2; realizes automated step feeding through the first drive unit 3; and achieves efficient and high-quality circumferential repair welding by utilizing welding stations distributed on both sides and welding guns 4 with rotation function. The entire device has a relatively simple structure, reducing purchase and maintenance costs compared to traditional large-scale automated laser welding equipment, and is more suitable for repair welding applications of conventional optical devices. Through the coordinated work of various components, batch, automatic, and accurate repair welding of optical devices is achieved, improving repair welding efficiency and quality, and has good economic and practical value.

[0066] Please refer to Figure 3 In a preferred embodiment, the fixed base 2 of the device is provided with a positioning hole 22, and the mounting base 1 is provided with a positioning post 12 that is adapted to the positioning hole 22.

[0067] During the process of installing the mounting base 2 onto the mounting base 1 to fix the optical device 100, the positioning post 12 and the positioning hole 22 serve as guides and positions. When the operator places the mounting base 2 above the mounting base 1, the positioning post 12 on the mounting base 1 needs to be aligned with the positioning hole 22 on the mounting base 2. Then, the mounting base 2 is lowered so that the positioning post 12 is inserted into the positioning hole 22. During this process, the positioning post 12 slides along the wall of the positioning hole 22 until the mounting base 2 is fully installed. At this point, every two adjacent L-shaped fixing plates 21 can accurately correspond to a mounting hole 11, thereby achieving joint clamping and fixing of the optical device 100 housed in the mounting hole 11.

[0068] This design ensures that, in actual operation, operators can guarantee that the mounting base 2 is always accurately and consistently positioned on the mounting base 1, without requiring significant time and effort to repeatedly adjust its position. Simply aligning the positioning pin 12 with the positioning hole 22 and lowering the mounting base 2 completes the installation process quickly, significantly reducing installation time and improving the assembly and operational efficiency of the entire welding repair device. This is particularly beneficial when performing batch welding repairs on optical components 100, significantly enhancing production efficiency.

[0069] Please refer to Figure 1 In one specific embodiment, the first driving unit 3 includes a first driving member 31, a slide rail 32 and a slider (not shown in the figure). The slide rail 32 is fixedly installed, the slider is connected to the mounting base 1 and is slidably installed on the slide rail 32, and the first driving member 31 is connected to the slider for driving the slider to reciprocate along the slide rail 32.

[0070] The sliding engagement between the slide rail 32 and the slider provides high-precision, low-friction linear guidance for the horizontal movement of the mounting base 1, effectively ensuring the accuracy and stability of the motion trajectory. The first drive component 31 serves as a power source, driving the entire mounting base 1 by driving the slider.

[0071] Specifically, the first driving component 31 can be a servo motor or a stepper motor, and in conjunction with a lead screw and nut mechanism or a gear and rack mechanism, etc., the rotational motion of the driving component is converted into the precise linear displacement of the slider. By programmably controlling the start, stop, direction and angular displacement of the first driving component 31, the moving distance, speed and stopping position of the mounting base 1 can be precisely controlled, thereby realizing an automated process of sequentially and precisely stepping each optical device 100 to the welding station.

[0072] Furthermore, please refer to... Figure 1 In one specific embodiment, the second drive unit 5 includes a second drive member 51, a rotating seat 52 and a turntable 53. The turntable 53 is rotatably disposed below the slide rail 32 via the rotating seat 52. The second drive member 51 is connected to the rotating seat 52 for driving the rotating seat 52 and the turntable 53 to rotate together. The welding torch 4 is mounted on the turntable 53.

[0073] The welding torch 4 is mounted on the turntable 53 and rotates with it, enabling more comprehensive welding of the optical device 100. Compared to traditional fixed welding torches that can only weld from one direction or a few fixed points, this design ensures that every area requiring welding can be reached, avoiding welding dead spots and greatly improving welding quality and reliability.

[0074] Specifically, the second drive unit 5 uses the second drive component 51 as its power source. When the second drive component 51 is activated, it outputs power and transmits it to the rotary seat 52 through a specific transmission method (such as gear transmission, belt transmission, etc., depending on the connection design between the second drive component 51 and the rotary seat 52).

[0075] After receiving power from the second driving member 51, the rotating seat 52 begins to rotate around its own axis. Since the turntable 53 is rotatably mounted below the slide rail 32 via the rotating seat 52 and is connected to the rotating seat 52, the turntable 53 will rotate together with the rotating seat 52.

[0076] The welding torch 4 is mounted on the turntable 53. When the turntable 53 rotates, the welding torch 4 also moves in a circular motion around the axis of the turntable 53. During the welding process, this circular motion enables the welding torch 4 to perform circumferential welding on the optical device 100, ensuring that the gap between the optical device body 101 and TO102 is fully welded.

[0077] Please refer to Figure 1 and Figure 4 This application also includes a third driving unit 6, which is connected to the welding torch 4 for driving the welding torch 4 to make fine adjustments along the X, Y, and Z axes of the spatial rectangular coordinate system so that the welding torch 4 is aligned with the optical device 100.

[0078] In a preferred embodiment, the third drive unit 6 includes three independent linear drive modules 61, which are respectively arranged in the X, Y and Z axes, and together constitute a three-axis fine-tuning mechanism.

[0079] The third drive unit 6 provides the welding torch 4 with the ability to adjust its position in three-dimensional space. Through this mechanism, the end position of the welding torch 4 can be calibrated to ensure that its solder joint can be accurately aligned with the specific welding part of the optical device 100 (the gap between the body 101 and TO102).

[0080] Specifically, the linear drive module 61 can be a linear actuator such as an electric cylinder, a pneumatic cylinder, or a servo slide. By programmably controlling the movement of each module, fine-tuning of the end position of the welding torch 4 can be achieved.

[0081] Please refer to Figure 5 This application also includes a mounting plate 7 and a frame 8. The first drive unit 3, the second drive unit 5 and the welding torch 4 are all mounted on the mounting plate 7, and the mounting plate 7 is fixed to the frame 8.

[0082] Mounting plate 7 is used to support the first drive unit 3, the second drive unit 5 and the welding gun 4. The frame 8 serves as the main support for the entire device, providing a stable mounting platform for mounting plate 7.

[0083] Specifically, the mounting plate 7 is provided with two uprights 71, and a horizontal plate 72 is connected between the uprights 71. The first drive unit 3 is disposed on the horizontal plate 72, and the second drive unit 5 is located between the two uprights 71.

[0084] Two uprights 71 are vertically fixed to the mounting plate 7, providing stable vertical support for the horizontal plate 72 and the first drive unit 3 mounted on the horizontal plate 72. The uprights 71 and the horizontal plate 72 may be made of high-strength materials, such as steel or hard aluminum alloy, to ensure that they can withstand the weight of the components above and the vibrations and stresses generated during operation.

[0085] By placing the first drive unit 3 on the horizontal plate 72 and the second drive unit 5 between the two columns 71, a compact layout of the internal space of the device is achieved. This layout makes full use of the vertical and horizontal space within the limited installation space, improves space utilization, and makes the entire device more compact and flexible, suitable for production environments and space requirements of different sizes.
