Description

Technical Field

[0001] This invention belongs to the field of optical component technology, specifically relating to an optical component disassembly device and disassembly method. Background Technology

[0002] With the continuous development of the optical communication industry, especially as 5G gradually enters the large-scale deployment stage, the development of optical components has also been promoted. Since optical components account for an increasingly large proportion of the cost of communication networks, they constrain the overall cost of the network; therefore, reducing the price of optical components is an important goal of the optical communication industry.

[0003] In the optical communication industry, reducing the production cost of optical components is of paramount importance. The first step is to reduce material costs, and among material costs, material waste is particularly prominent. Controlling material waste has a profound impact on reducing the cost of optical components.

[0004] In current optical component manufacturing, the housing and TO (Transistor Outline) portion of the optical component are primarily connected using laser welding. The TO in optical components is a mainstream coaxial packaging technology in the optical communication field, commonly used in TO packaging. CAN bus is used for packaging core optoelectronic devices such as lasers (LDs) and photodiodes (PDs). To ensure the strong weld between the housing and the TO (Transfer Tolerance) section, the disassembly force after welding is very large (assuming the process is fixed and cannot be changed). Direct disassembly would cause excessive stress on the optical component housing, resulting in deformation. This deformation would cause displacement of the internal structure, rendering it unusable, ultimately leading to losses in material and labor costs. This waste of material and labor costs, coupled with the high cost of materials, makes it difficult to effectively control manufacturing costs.

[0005] Because the laser welding between the housing and the TO (Transfer Tolerance) portion of the optical component requires excessive disassembly force, existing optical components can only be disassembled and recycled from the TO portion. This results in wasted material and labor costs, making it impossible to effectively control manufacturing costs. Therefore, it is necessary to design a device and method that can disassemble the housing and the TO portion of the optical component separately. Summary of the Invention

Detailed Implementation

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0022] Example 1 like Figures 1 to 3 As shown, this embodiment designs a disassembly device for optical components, including a buffer pad 2, a stroke cylinder 3, a clamp body 4, a support slider 5, a base plate 6, a handle 7, a motor fixing bolt 8, a fixing kit 9, a motor 10, a motor adapter 11, a support body 12, a support body base 14, a motor bracket 16, a bracket fixing bolt 17, and a cutting tool 18, etc.

[0023] The base plate 6 adopts a square plate structure and has several screw holes to facilitate the passage of bolts.

[0024] The clamp body 4 is mounted on the base plate 6. The clamp body 4 has a transverse positioning hole for accommodating and positioning the housing 101 of the optical component 1. The lower part of the clamp body 4 is horizontally slidably connected to a support slider 5, which is fixedly connected to the base plate 6. Pins for locking the clamp body 4 in position are provided on the clamp body 4, the slider, or the base plate 6.

[0025] A buffer pad 2 is provided inside the positioning hole. The buffer pad 2 is connected to the piston rod of the stroke cylinder 3 and is controlled by the stroke cylinder 3 to move laterally to push the housing 101 horizontally out. The buffer pad 2 is detachably connected to the piston rod of the stroke cylinder 3 so that the initial depth of the positioning hole can be adjusted by replacing the buffer pad 2 with one of different thicknesses, thereby adapting to different types and specifications of optical components 1.

[0026] The cutting tool 18 is drivenly connected to the output shaft of the motor 10. The cutting tool 18 can move vertically to cut the welded portion 103 between the TO portion 102 of the optical component 1 and the housing 101. The TO portion 102 is welded to the rear end of the housing 101, and there are several weld points at the welded portion 103. The cutting tool 18 cuts along the plane where each weld point is located.

[0027] A support body 12 is fixed on the base plate 6. A motor bracket 16 is rotatably connected to the upper end of the support body 12, and the motor 10 is fixed to the end of the motor bracket 16. A bracket fixing bolt 17 and a torsion spring are provided at the rotatable connection between the support body 12 and the motor bracket 16. The bracket fixing bolt 17 serves as the shaft for the rotation of the motor bracket 16, and the torsion spring is used for the reset of the motor bracket 16. A motor adapter 11 is fitted over the motor 10, and a fixing kit 9 ​​is fitted over the motor adapter 11. The fixing kit 9 ​​is fixedly connected to the motor bracket 16. A motor fixing bolt 8 passes through the motor adapter 11 and the fixing kit 9 ​​and abuts against the motor 10. A handle 7 is connected to the outer wall of the fixing kit 9.

[0028] An arc-shaped scale 1601 is connected to the motor bracket 16, and the angle of the arc-shaped scale 1601 is indicated by the pointer on the support body 12.

[0029] Example 2 This embodiment designs a method for disassembling an optical component, using the optical component disassembly device described in Embodiment 1. The disassembly method includes the following steps: S1: Fix the housing 101 of the optical component 1 and expose the welding part 103 between the TO portion 102 of the optical component 1 and the housing 101.

[0030] Specifically: Insert the housing 101 of the optical component 1 into the positioning hole of the fixture body 4, and select a buffer pad 2 of appropriate thickness to ensure that the welded part 103 between the TO part 102 of the optical component 1 and the housing 101 is outside the positioning hole. The technician slides the fixture body 4 horizontally to adjust the position of the optical component 1 so that the welded part 103 between the TO part 102 and the housing 101 is directly below the cutting tool 18.

[0031] S2: Start the motor 10 to drive the cutting tool 18, control the cutting tool 18 to move downward and cut off the welded part 103.

[0032] Specifically: After the motor 10 is powered on, the technician holds the handle 7 and controls the motor 10 to move downwards. During this process, the motor bracket 16 rotates around the bracket fixing bolt 17 and compresses the torsion spring. The cutting tool 18 moves downwards and rotates simultaneously, thereby cutting the welded part 103 between the TO portion 102 of the optical component 1 and the housing 101. The cutting process does not damage the appearance of the housing and the TO portion 102, nor does it deform the housing and the TO portion 102, preserving the original state of the optical component 1 and meeting the requirement of simultaneous recycling of both. During the cutting process, the shearing force applied by the cutting tool 18 does not exceed 49N. While ensuring a smooth cutting edge and preventing the temperature from becoming too high (30-50°C), it does not deform the housing of the optical component 1, thus avoiding waste of materials and manpower and optimizing the usage effect.

[0033] After the welded part 103 is cut off, release the handle 7. The motor 10 will reset under the elastic force of the torsion spring, causing the cutting tool 18 to rise to the initial position. At this time, the piston of the stroke cylinder 3 extends and retracts once more, thereby pushing out the housing 101 in the positioning hole. The TO part 102 and the housing 101 can then be collected separately for recycling.

[0034] The disassembly device in this solution uses a cutting method to disconnect the connection between the housing 101 and the TO portion 102 of the optical component 1. This allows the housing 101 and the TO portion 102 to be recycled separately, thereby improving the recycling rate, reducing raw material costs and material waste. It also reduces the disassembly force (i.e., shearing force) experienced when separating the housing 101 and the TO portion 102, avoiding damage to them. The disassembly is highly precise and reliable, completing the cutting of the solder joints of the optical component 1 in one step, making it convenient and quick. It is compatible with various types of optical component products, offering strong compatibility.

[0035] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
