Description

Technical Field

[0001] This invention relates to the field of laser processing equipment technology, and in particular to a pump source component welding fixture. Background Technology

[0002] The pump source, as an energy source, generates photons to excite the gain medium. Currently, high-power semiconductor lasers (LDs) are generally used as pump sources, primarily to convert electrical energy into optical energy.

[0003] like Figure 1 As shown, pump source 1 needs to be mounted on water-cooled plate 2 for better heat dissipation. Pump source 1 and water-cooled plate 2 are a single unit, collectively referred to as pump source assembly. Each pump source 1 contains a varying number of electrode posts 11 for signal transmission with external components. The electrode posts 11 can be nickel-plated copper posts, connected to wires by soldering. Currently, the operation is manual. The operator moves the pump source assembly to the workbench, holding the wires in one hand and a soldering iron in the other, and solders the wires one by one to the electrode posts 11 of the pump source.

[0004] In the process of developing this invention, the inventors discovered at least the following problems in the prior art: As production scale gradually increases, multiple operators are needed to perform the soldering operation of the pump source. When their skill level is low, the consistency of the solder joints cannot be guaranteed, and frequent rework of solder joints can easily damage the pump source. In addition, as the current required for the pump source to operate gradually increases, the diameter of the connecting wires also gradually increases, requiring higher soldering temperatures and times. Wires have a thermal conductivity effect, and the temperature of the wires is higher closer to the solder joint. During soldering, the operator needs to hold the wires and keep them in a fixed position. Prolonged soldering operations can easily cause burns to the operator's hands, and improper technique can also lead to poor soldering. Summary of the Invention

Detailed Implementation

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0031] Figure 3 This is a schematic diagram of the structure of a pump source component welding fixture proposed in an embodiment of the present invention.

[0032] Combination Figures 1 to 3 As shown in the figure, this embodiment of the invention proposes a pump source assembly welding fixture. The pump source assembly includes a pump source 1 and a water-cooled plate 2 fixed together, with the pump source 1 mounted on the water-cooled plate 2. The pump source 1 has electrode posts 11. The pump source 1 can be a semiconductor laser, and the water-cooled plate 2 has cooling channels in which the coolant circulates to dissipate heat from the semiconductor laser. The number of pump sources 1 on a single water-cooled plate 2 can be designed according to actual needs. The electrode posts 11 on a single pump source 1 typically include one positive electrode post and one negative electrode post, but in some cases, the number of electrode posts 11 can be more.

[0033] This invention provides a pump source component welding fixture comprising a base 3 and a clamping block 4. The base 3 is used to hold the pump source component. The sides and rear of the base 3 are provided with upward-facing guards, which clamp and limit the front and sides of the water-cooled plate 2. The front of the base 3 has an opening for the pump source component to enter in a first direction. The spacing between the guards on the two sides of the base 3 is adapted to the width of the pump source component. In one embodiment, the base 3 is made of bakelite. Bakelite, chemically known as phenolic resin, has high mechanical strength, good insulation, heat resistance, and corrosion resistance. Bakelite also has anti-static properties, protecting the pump source component from electrostatic damage. The height of the guards is designed according to the thickness of the water-cooled plate 2. In one embodiment, the thickness of the guards is 1 to 4 mm.

[0034] The clamp 4 is fixed to the base 3. The clamp 4 is used to fix the wire and provide a welding platform for the electrode post 11 and the wire. Soldering of the electrode post 11 and the wire can be done using tin soldering. There are various ways to fix the wire, such as using a clamp to hold the wire, or using a wire groove to hold the wire in place. When welding the electrode post 11 and the wire, the wire and the electrode post are opposite each other, located above the clamp 4, with the side of the wire abutting against the side of the electrode post to ensure welding quality. In one embodiment, the clamp 4 is made of polytetrafluoroethylene (PTFE), with a melting point of 327°C. It can withstand the high temperatures (around 260°C) generated by long-term soldering with a soldering iron and does not stick to solder, facilitating the cleaning of solder slag after soldering and preventing flux corrosion.

[0035] During actual installation, the operator pushes the pump source assembly into the front opening of the base 3, and then slides the pump source assembly inward along the first direction until the front of the water-cooled plate abuts against the front edge of the base 3. At this time, the electrode post is located above the clamping block.

[0036] The pump source component welding fixture according to embodiments of the present invention, by setting a stop edge and a clamping block on the base, allows the stop edge to limit the pump source component on the base, ensuring that the pump source component does not shift during welding and improving welding stability. The clamping block can fix the wire and provide a welding platform for the electrode post and the wire, thereby avoiding the problems of easy burns to the operator's hands and poor welding due to deformation of the technique when handling the wire by hand, as in the prior art. The pump source component welding fixture of the present invention can also be used in conjunction with automatic soldering equipment to realize automated equipment to replace manual welding, further improving production efficiency and reducing production costs.

[0037] In some embodiments, such as Figure 3 As shown, the base 3 has first cutout areas 31 on both sides for removing the pump source assembly. The corners of the first cutout areas 31 are chamfered to prevent scratches. The first cutout areas 31 expose a portion of the water-cooling plate 2, allowing for easy hand gripping and removal of the pump source assembly. The retaining edges include a first retaining edge 33 and a second retaining edge 34. The first retaining edge 33 is located behind the first cutout areas 31, and the second retaining edge is located in front of the first cutout areas 31. The first retaining edge 33 clamps only the two sides of the water-cooling plate 2, while the second retaining edge 34 clamps both sides and the front of the water-cooling plate.

[0038] Combination Figure 2 , Figure 3 As shown, some water-cooled plates 2 have feet 21 on their bottom surfaces, and the base 3 includes a seat 32. The upper surface of the seat 32 has a recessed area 35, the depth of which is the same as the height of the feet 21. The recessed area 35 can further ensure the positioning accuracy of the pump source assembly on the pump source assembly welding fixture, so that the water-cooled plate 2 can be placed horizontally on the seat 32, reducing the welding difficulty.

[0039] Combination Figure 3 , Figure 4 As shown, the base 3 is provided with a plurality of first fixing holes 36, and the clamping block 4 is provided with a plurality of second fixing holes 44. The first fixing holes 36 and the second fixing holes 44 are used to install fasteners to fix the base 3 and the clamping block 4 together.

[0040] In some embodiments, the clamping block 4 has a boss 41 extending toward the pump source 1. The boss 41 is configured as a platform for welding. After the pump source assembly is installed in the welding fixture, the electrode post 11 is located above the boss 41. The boss 41 has a gap between its side near the pump source 1 and the root of the electrode post 11. The boss 41 is designed according to the shape around the electrode post 11 of the pump source. This gap is to prevent the boss from damaging the electrode post or temperature sensor wiring harness of the pump source assembly. Optionally, the gap distance is 3-6 mm. It is understood that the area of ​​the boss 41 is larger than the welding area to prevent solder balls and solder dross from falling onto the water cooling plate during the welding process. The number of bosses 41 corresponds to the number of pump sources 1 on the pump source assembly. In one example, there are two pump sources 1 on the pump source assembly, arranged side by side. Correspondingly, there are also two bosses 41.

[0041] The positive and negative electrodes of electrode post 11 are parallel to each other. The width of the boss 41 is greater than the distance between the positive and negative electrodes. Both ends of the boss 41 are provided with upward-facing third guard edges 42. The third guard edges 42 can ensure that after the wire is fixed, the wire core will not shift out of the outside of the boss during soldering.

[0042] Combination Figure 5 , Figure 6 As shown, the clamping block 4 has a second hollow area 46 below the boss 41. The bottom surface of the boss 41 is spaced from the upper surface of the water-cooled plate 2. The second hollow area 46 can prevent the water-cooled plate 2 from interfering with the boss 41.

[0043] The upper surface of the clamping block 4 is provided with a first wire fixing groove 43 and a second wire fixing groove 45. The first wire fixing groove 43 and the second wire fixing groove 45 are parallel to each other and extend to the side of the boss 41. The first wire fixing groove 43 is located adjacent to the outer side of the negative terminal, and the second wire fixing groove 45 is located adjacent to the outer side of the positive terminal. The inner diameter of the first wire fixing groove 43 and the second wire fixing groove 45 is less than or equal to the outer diameter of the wire. The insulation layer of the wire is made of rubber or plastic, which can undergo a certain deformation under external force. Therefore, the first wire fixing groove 43 and the second wire fixing groove 45 can hold the wire tightly, preventing burns caused by touching the wire with one's hands. Optionally, the first wire fixing groove 43 and the second wire fixing groove 45 are 1mm smaller than the outer diameter of the wire to facilitate the insertion of the wire.

[0044] The first wire fixing groove 43 and the second wire fixing groove 45 are divided into a first part and a second part, with the side wall extending from the boss 41 from the clamping block 4 as the boundary. The first part consists of the first wire fixing groove 43 and the second wire fixing groove 45 on the boss 41, and the second part consists of the first wire fixing groove 43 and the second wire fixing groove 45 not on the boss. The cross-section of the first part is semi-circular or U-shaped, which facilitates the clamping of the wire sheath. The cross-section of the second part is a quarter-circle arc, which coincides with the inner wall of the third retaining edge 42. After excess solder wets the wire during soldering, the quarter-circle arc can accommodate various shapes of the wire core after tinning.

[0045] The pump source component welding fixture provided in this embodiment of the invention can be used with an automatic soldering machine to realize the automatic welding of the electrode posts and wires of the pump source component, replacing manual welding, improving welding consistency and solder joint quality, and reducing labor costs.
