Description

Technical Field

[0001] This utility model belongs to the field of power distribution board welding technology, specifically relating to a modular welding fixture for power distribution boards. Background Technology

[0002] To reduce cable material costs, current base station antennas primarily employ power divider board conversion solutions to minimize cable usage and lower costs. During assembly, power divider boards utilize automated welding fixtures. However, these fixtures are simple in structure, capable of welding only one set of cables at a time and adaptable only to one cable length. Welding cables of different lengths requires frequent fixture changes, necessitating repeated adjustments to the automated welding equipment each time, resulting in low welding efficiency. Utility Model Content

[0003] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a modular welding fixture for power dividers. This fixture aims to solve the problem that existing power divider welding fixtures can only weld one set of cables at a time, resulting in low efficiency when welding cables of different lengths.

[0004] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a modular welding fixture for a power distribution board. The fixture includes a base and a cover plate. The base has a set of first mounting slots and a set of second mounting slots. There are multiple first mounting slots and second mounting slots, and adjacent first mounting slots and second mounting slots are staggered. Each first mounting slot and second mounting slot includes a power distribution board placement slot and a first sliding groove and a second sliding groove at both ends of the power distribution board placement slot. A wire groove is formed between the first sliding groove and the second sliding groove and the power distribution board placement slot. Movable blocks are adjustable inside the first sliding groove and the movable blocks have positioning grooves corresponding to the wire grooves. A first clearance hole corresponding to the power distribution board placement slot is formed on the cover plate. The cover plate is magnetically fixed to the base.

[0005] Preferably, the width of the first slide groove and the second slide groove is smaller than the width of the power divider plate placement groove, the power divider plate placement groove of the first mounting groove is located at the first slide groove of the adjacent second mounting groove, and the power divider plate placement groove of the second mounting groove is located at the second slide groove of the adjacent first mounting groove.

[0006] Furthermore, the movable block is slidably connected inside the first and second slide grooves. The movable block has mounting holes, and the inner bottom walls of the first and second slide grooves have elongated holes that penetrate the base. Bolts are fixedly connected inside the mounting holes and elongated holes.

[0007] Furthermore, multiple first magnetic buckles are fixedly connected to the base, and second magnetic buckles corresponding to the first magnetic buckles are fixedly connected to the cover plate. The multiple first magnetic buckles are located on both sides of the wire groove.

[0008] Furthermore, the cover plate includes a first cover plate and a second cover plate. Both the first cover plate and the second cover plate are provided with a second clearance hole corresponding to the movable block. The first clearance hole corresponding to the first mounting groove is located on the first cover plate and is an open structure. The first clearance hole corresponding to the second mounting groove is located on the second cover plate and is an open structure.

[0009] Furthermore, handle slots are provided on both sides of the power distribution board placement slot.

[0010] Furthermore, shims are fixedly connected to both sides of the lower surface of the base.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses movable blocks that can be adjusted to position the cable in the first and second slides, so that the length of the cable can be adjusted. This makes it compatible with the combination design of different spacings of most medium frequency oscillators, thereby welding power divider modules with different cable lengths, reducing the machine adjustment time when changing tooling, and improving production efficiency. At the same time, the adjacent first and second mounting slots are staggered, that is, a staggered inlay layout structure is adopted, which allows more power divider board components to be loaded in the limited base space. This helps to reduce the tooling area, reduce the tooling manufacturing cost, and has a higher compatibility with general automatic welding machines. 2. This utility model fixes the power divider assembly inside the base, making the base, the main body of the power divider, and the cable a modular unit. The base is then assembled into an automated welding fixture. For automated equipment with a single welding fixture, the fixture can be changed for operation, achieving a balance between human and machine efficiency without waste. For automated welding equipment with a double welding fixture, while the automated equipment is operating at one end, a person can manually assemble the power divider assembly at the other end, achieving the same goal of human-machine balance and maximizing efficiency, thus improving the efficiency of automated welding.

[0019] This specific embodiment is a modular welding fixture for a power distribution board, and its structural schematic diagram is shown below. Figures 1-6 As shown, the fixture includes a base 1 and a cover plate 2. The base 1 has a set of first mounting slots 3 and a set of second mounting slots 4. There are multiple first mounting slots 3 and second mounting slots 4, and adjacent first mounting slots 3 and second mounting slots 4 are staggered. The first mounting slots 3 and second mounting slots 4 are used to place the power divider assembly 111. The cover plate 2 is used to fix the power divider assembly 111. The power divider assembly 111 includes a power divider body 112 and a cable 113. Both the first mounting slots 3 and second mounting slots 4 include a power divider placement slot 5 and first sliding joints at both ends of the power divider placement slot 5. The first slide 6 and the second slide 7 are both provided with wire grooves 8 between them and the power divider plate placement groove 5. There are two wire grooves 8, which is the same as the number of cables 113 on the power divider plate body 112. The first slide 6 and the second slide 7 are both provided with adjustable movable blocks 9. The movable blocks 9 are provided with positioning grooves 10 corresponding to the wire grooves 8. The positioning grooves 10 can position the wire core and the mesh layer. The cover plate 2 is provided with a first clearance hole 11 corresponding to the power divider plate placement groove 5. The welding equipment performs welding through the first clearance hole 11. The cover plate 2 is magnetically fixed to the base 1.

[0020] like Figure 1 and Figure 2As shown: In this embodiment, the width of the first slide groove 6 and the second slide groove 7 is smaller than the width of the power distribution board placement groove 5. The power distribution board placement groove 5 of the first mounting groove 3 is located at the first slide groove 6 of the adjacent second mounting groove 4, and the power distribution board placement groove 5 of the second mounting groove 4 is located at the second slide groove 7 of the adjacent first mounting groove 3. In this way, the adjacent first mounting groove 3 and the second mounting groove 4 are staggered, that is, a staggered inlay layout structure is adopted, which allows more power distribution board components 111 to be loaded on the limited space of the base 1, which helps to reduce the tooling area and reduce the tooling manufacturing cost.

[0021] like Figure 2 and Figure 5 As shown: In this embodiment, the movable block 9 is slidably connected inside the first slide groove 6 and the second slide groove 7 to prevent the movable block 9 from shaking. The movable block 9 is provided with a mounting hole 13. The inner bottom wall of the first slide groove 6 and the second slide groove 7 are provided with an elongated hole 14 that penetrates the base 1. Bolts are fixedly connected in the mounting hole 13 and the elongated hole 14. The bolts include screws and nuts. The screws penetrate the mounting hole 13 and the elongated hole 14 and are threadedly connected to the nuts at the bottom. The position of the movable block 9 inside the first slide groove 6 and the second slide groove 7 is adjusted by the bolts, thereby accurately positioning the position of the cable 113. The positioning accuracy of the cable 113 is improved to the 0.1mm level. It can be adjusted only when it is first debugged or when changing to a different cable length, which is more flexible. For different gaps in the 1727 oscillator, the assembly and automated welding of different 1727 power distribution board modules can be achieved simply by adjusting the position of the movable block 9, providing a more flexible position adjustment capability.

[0022] like Figure 2 and Figure 3 As shown: In this embodiment, a plurality of first magnetic buckles 15 are fixedly connected to the base 1. The first magnetic buckles 15 are fixedly connected to the upper side of the base 1 by screws. A second magnetic buckle 16 corresponding to the first magnetic buckle 15 is fixedly connected to the cover plate 2. The second magnetic buckle 16 is fixedly connected to the lower side of the cover plate 2 by screws. The plurality of first magnetic buckles 15 are located on both sides of the wire groove 8, which better compresses the cable 113. After all the power divider components 111 on the base 1 are assembled, the cover plate 2 is pressed onto the base 1. At this time, the first magnetic buckle 15 and the second magnetic buckle 16 are magnetically attracted to fix the power divider components 111, making the clamping simple and quick.

[0023] For ease of use of cover plate 2, such as Figure 1 and Figure 3As shown: In this embodiment, the cover plate 2 includes a first cover plate 201 and a second cover plate 202. Both the first cover plate 201 and the second cover plate 202 are provided with second clearance holes 12 corresponding to the movable block 9. The first clearance hole 11 corresponding to the first mounting groove 3 is located on the first cover plate 201 and is an open structure. The first clearance hole 11 corresponding to the second mounting groove 4 is located on the second cover plate 202 and is an open structure. In this way, the cover plate 2 has a smaller area, is easier to process and manufacture, and is more convenient to handle.

[0024] like Figure 4 As shown: In this embodiment, both sides of the power divider placement slot 5 are provided with handle slots 17. The power divider body 112 can be easily placed into or taken out of the power divider placement slot 5 through the handle slots 17, which is very convenient.

[0025] To better assemble base 1 into the automated welding fixture, such as Figure 1 and Figure 4 As shown: In this embodiment, both sides of the lower surface of the base 1 are fixedly connected with shims 18. The shims 18 not only raise the base 1, but also make it more stable.

[0026] Working principle: When in use, the power divider assembly 111 is placed in the first mounting slot 3 and the second mounting slot 4. At this time, the power divider body 112 of the power divider assembly 111 is located in the power divider placement slot 5. Then, adjust the position of the movable block 9 in the first slide 6 and the second slide 7 according to the required cable length. Next, put the cable 113 into the wire groove 8 between the first slide 6 and the second slide 7, and make one end of the cable 113 located in the positioning groove 10. At this time, the other end of the cable 113 is located at the welding position of the power divider body 112. Then, press the cover plate 2 on the base 1 to fix the power divider assembly 111, thereby assembling the power divider assembly 111 into the base 1. Then, assemble the base 1 into the automated welding fixture. Then, start the automated equipment and use a dual-axis soldering iron device to automatically weld the wire cores, mesh layers and other solder joints on the power divider body 112. After welding is completed, take it out and place it as required.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
