Description

Technical Field

[0001] This invention relates to the field of tooling technology for die-casting oscillators for base station antennas, and particularly to a dual-purpose tooling fixture for tinning and reflow soldering of die-cast oscillators. Background Technology

[0002] Die-cast oscillators for base station antennas are key components of radio frequency systems. The production process requires tinning and reflow soldering of cables and oscillator feed plates.

[0003] The existing tooling has the following defects in actual production: it is difficult to clamp and position the die-cast oscillators and cable assemblies, the oscillators are prone to displacement, and the outer conductor and inner core of the cable are misaligned, resulting in misaligned soldering, high rates of cold solder joints and misaligned solder joints after reflow soldering, and affecting the product interoperability index; ordinary fixtures use mechanical clamping structures, which are prone to thermal deformation under the high temperature of reflow soldering, and the mechanical clamping blocks are prone to damaging the oscillators and cable sheaths, and the mechanical clamping structure is prone to jamming after high temperature, making it inconvenient to pick up and put down workpieces; there are many oscillators and cable bundles, and the heat is not easy to dissipate during the welding process. At the same time, the hot air circulation is poor, the heating is uneven during reflow soldering, and the welding consistency of products at each station is poor; one set of tooling can only be adapted to the production of a single set of oscillators, and the compatibility of array batch processing is poor. It cannot be compatible with the transfer of soldering stations and processing in the reflow oven at the same time. Different fixtures need to be changed between processes, and repeated disassembly and assembly are required, resulting in low production efficiency.

[0004] Therefore, there is an urgent need to develop a dual-purpose tooling fixture for die-casting oscillators for soldering and reflow soldering, to address the shortcomings of the existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-purpose tooling fixture for die-cast oscillators, capable of simultaneously handling the tinning process of die-cast oscillators and the high-temperature reflow soldering process. It adopts a magnetic clamping structure to replace mechanical locking, avoiding high-temperature jamming and damage to the workpiece. It achieves precise positioning of the die-cast oscillator, cable outer conductor, and cable inner core, improving the consistency of tinning and reflow soldering, reducing poor solder joints and misaligned solder joints, and supporting array-type batch processing.

[0006] To achieve the objectives of this invention, the following technical solution is adopted:

[0007] A dual-purpose fixture for soldering and reflow soldering of die-cast oscillators includes a carrier assembly and a cable positioning assembly. The carrier assembly includes a limiting tray and a first magnetic chuck. The limiting tray has an oscillator limiting hole group and a hollow groove group. The first magnetic chuck is mounted on the limiting tray. The cable positioning assembly includes a wire pressing fixture and a second magnetic chuck. The wire pressing fixture has a wire pressing part for pressing the cable. The second magnetic chuck is mounted on the wire pressing fixture. The hollow groove group allows hot air to pass through. The cable positioning assembly covers the carrier assembly. The first magnetic chuck and the second magnetic chuck attract each other, so that the wire pressing fixture presses and fixes the die-cast oscillator assembly placed in the oscillator limiting hole group, and the wire pressing part is correspondingly pressed with the cable of the die-cast oscillator assembly.

[0008] A further improvement is that the limiting tray is an array-type plate, and the oscillator limiting hole group is arranged in multiple arrays, with each group of the oscillator limiting hole group corresponding to a set of die-cast oscillator components.

[0009] A further improvement is that the hollowed-out groove group includes multiple elongated slots, which are evenly distributed on the limiting tray plate.

[0010] A further improvement is that the limiting tray is also provided with a first suction groove, which is opened around the vibrator limiting hole group, and the first magnetic suction component is embedded in the first suction groove.

[0011] A further improvement is that the crimping fixture is provided with a second suction groove, and the second magnetic suction component is embedded in the second suction groove.

[0012] A further improvement is that the wire pressing fixture is a star-shaped pressing block structure, and the wire pressing part includes a first wire pressing ear, a second wire pressing ear, and a third wire pressing ear, which are distributed on the outer periphery of the wire pressing fixture; the first wire pressing ear, the second wire pressing ear, and the third wire pressing ear are respectively used to press different cables to constrain the outer conductor and the inner core of the cable, so that the welding point of the cable and the feeder plate remains fixed in position.

[0013] A further improvement is that a ventilation hole is provided in the center of the crimping fixture, and the ventilation hole runs through the crimping fixture from top to bottom.

[0014] A further improvement is that the first magnetic attractor and the second magnetic attractor are high-temperature resistant magnets.

[0015] A further improvement is that the carrier assembly also includes a sensing positioning plate, which is mounted on the side of the limiting tray.

[0016] A further improvement is that the wire pressing tool is made of high-temperature resistant insulating material.

[0017] The beneficial effects of this invention are as follows:

[0018] The tooling fixture of this invention adopts a magnetic clamping structure. The first magnetic suction component and the second magnetic suction component attract each other, and the wire clamping fixture clamps and positions the die-cast oscillator, the outer conductor of the cable, and the inner core of the cable. In the high-temperature environment of reflow soldering, there will be no problem of structural jamming or cable misalignment. The workpiece is simple and convenient to pick up and put down, and it also avoids the problem of mechanical clamping blocks damaging the oscillator and cable in the traditional mechanical buckle locking method.

[0019] This invention enables batch processing by setting array oscillator limiting hole groups on the limiting tray, allowing multiple sets of die-cast oscillator assemblies to be clamped at one time; by opening hollow slot groups on the limiting tray and opening ventilation holes on the wire pressing fixture, reflow soldering hot air can flow smoothly, the workpiece is heated evenly, improving the consistency of tinning and reflow soldering, and reducing poor solder joints and misaligned solder joints.

[0020] This invention provides a two-in-one tooling system. During the soldering process, the entire tooling is transferred to the soldering station to complete the soldering. After the soldering is completed, the entire tooling can be directly sent into the reflow oven. The hot air for reflow soldering flows through the hollow slots of the limiting tray and the ventilation holes of the wire pressing tooling to heat the welding position and complete the reflow soldering. There is no need to change the fixture between processes, which reduces the positional offset caused by repeated disassembly and reassembly of the vibrator and cable, and improves production efficiency.

[0033] Please refer to the attached document. Figure 1 To be continued Figure 6This invention provides a dual-purpose fixture for soldering and reflow soldering of die-cast oscillators. The fixture includes a carrier assembly 20 and a cable positioning assembly 30. The carrier assembly 20 includes a limiting tray 21 and a first magnetic suction element 22. The limiting tray 21 has an oscillator limiting hole group 211 and a hollow groove group 212 for limiting the die-cast oscillator. The first magnetic suction element 22 is mounted on the limiting tray 21. The cable positioning assembly 30 includes a wire clamping fixture 31 and a second magnetic suction element 32. The wire clamping fixture 31 has a wire clamping mechanism for clamping the cable. The first magnetic 22 and the second magnetic 32 are mounted on the wire pressing fixture 31. The hollow groove group 212 and the ventilation hole 315 are used for hot air penetration. The cable positioning assembly 30 covers the top of the carrier assembly 20. The first magnetic 22 and the second magnetic 32 attract each other, so that the wire pressing fixture 31 presses and fixes the die-cast oscillator assembly 10 placed in the oscillator limiting hole group 211, and the wire pressing part is correspondingly pressed with the cable of the die-cast oscillator assembly 10.

[0034] The following is a detailed description of the structure and principle of a dual-purpose tooling fixture for die-casting oscillators and reflow soldering, based on an embodiment of the present invention:

[0035] Specifically, in this embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the die-cast oscillator assembly 10 is the workpiece to be processed, which is supported and clamped by the tooling fixture. The die-cast oscillator assembly 10 is a base station antenna die-cast oscillator assembly 10. The die-cast oscillator assembly 10 includes an oscillator body 101, a cable outer conductor 102, a cable inner core 103, and a feed plate 104. The oscillator body 101 is a roughly square die-cast metal body. During the production process, the cable and the feed plate 104 need to undergo tinning and reflow soldering processes.

[0036] Specifically, the oscillator body 101 is provided with four oscillator arms extending diagonally, and the four oscillator arms are distributed in a cross shape. The four cables extend along the corresponding oscillator arms respectively, and bend and turn from the end of the oscillator arm, extending towards the corresponding feed plate 104.

[0037] In this embodiment, the cables on the die-cast oscillator assembly 10 are coaxial cables. The outer conductor 102 constitutes the outer conductor of the coaxial cable, and the inner core 103 constitutes the inner conductor. The inner core 103 extends from the end of the outer conductor 102. That is, each cable includes an outer conductor 102 and an inner core 103. The outer conductor 102 covers the outer periphery of the inner core 103, and the inner core 103 extends from the end of the outer conductor 102 and is correspondingly welded to the feed plate 104. The feed plate 104 is located on the oscillator body 101 near the central region. In this embodiment, there are two feed plates 104. Among the four cables, the inner cores 103 of the two cables arranged opposite each other along the first diagonal direction converge at one of the feed plates 104; the inner cores 103 of the other two cables arranged opposite each other along the second diagonal direction converge at the other feed plate 104.

[0038] Of the four cables, two cables extend from the left and right sides of the central area of ​​the oscillator body 101 toward the direction of the third pressure lug 313, and form an overlapping intersection below the third pressure lug 313, that is, one cable is above the other cable, and after crossing, they extend toward the corresponding feed plate 104 respectively; the other two cables bend and turn around from the end of their respective oscillator arms and extend toward the corresponding feed plate 104.

[0039] Specifically, in this embodiment, the bottom shape of the oscillator body 101 matches the oscillator limiting hole group 211 on the limiting tray 21. The oscillator limiting hole group 211 can be a contoured hole, rectangular hole, or combination hole structure adapted to the bottom shape of the oscillator body 101. When the die-cast oscillator assembly 10 is placed in the oscillator limiting hole group 211, it restricts the horizontal movement of the oscillator body 101. It can be understood that the limiting effect of the oscillator limiting hole group 211 on the oscillator body 101 can ensure that the die-cast oscillator assembly 10 will not be displaced due to vibration or hot air impact during soldering and reflow soldering.

[0040] Specifically, in this embodiment, such as Figure 3 and Figure 4 As shown, the carrier assembly 20 includes a limiting tray 21 and a first magnetic suction element 22. The limiting tray 21 is an array-type plate, and the oscillator limiting hole group 211 is arranged in multiple arrays, with each array of the oscillator limiting hole group 211 corresponding to a set of die-cast oscillator assemblies 10. The shape of the oscillator limiting hole group 211 matches the bottom shape of the oscillator body 101, and the hole walls of the oscillator limiting hole group 211 can limit the oscillator body 101 peripherally, thereby preventing the oscillator body 101 from shifting during soldering and reflow soldering. Preferably, in this embodiment, the limiting tray 21 can be provided with multiple arrays of oscillator limiting hole groups 211, which can clamp multiple sets of die-cast oscillator assemblies 10 at one time, realizing batch processing.

[0041] Specifically, in this embodiment, the perforated groove group 212 includes multiple elongated slots, which are evenly distributed on the plate of the limiting tray 21. The perforated groove group 212 can be disposed between adjacent vibrator limiting hole groups 211, or it can be disposed around the vibrator limiting hole groups 211. The perforated groove group 212 extends vertically through the plate of the limiting tray 21, allowing high-temperature hot air to pass through the perforated groove group 212 from below the limiting tray 21 and act on the welding point during reflow soldering, ensuring uniform heating of the workpiece. In addition, the perforated groove group 212 can also reduce the overall weight of the limiting tray 21, facilitating tooling transfer and handling.

[0042] Specifically, in this embodiment, the limiting tray 21 is further provided with a first suction groove 213, which is located around the vibrator limiting hole group 211. The first magnetic suction member 22 is embedded in the first suction groove 213. The first suction groove 213 can be a circular groove, a square groove, or an annular groove. The shape of the first magnetic suction member 22 matches the first suction groove 213. The first magnetic suction member 22 can be embedded and fixed in the first suction groove 213 by interference fit, bonding, or snap-fit. The crimping fixture 31 is provided with a second suction groove 314, and the second magnetic suction member 32 is embedded in the second suction groove 314. The second suction groove 314 is correspondingly provided with the first suction groove 213 on the limiting tray 21. When the crimping fixture 31 is closed on the limiting tray 21, the second magnetic suction member 32 and the first magnetic suction member 22 are aligned and attracted to each other.

[0043] Specifically, in this embodiment, such as Figure 5 and Figure 6 As shown, the cable positioning assembly 30 includes a wire clamping fixture 31 and a second magnetic suction component 32. The wire clamping fixture 31 has a star-shaped clamping block structure, and the wire clamping part includes a first wire clamping ear 311, a second wire clamping ear 312, and a third wire clamping ear 313, which are distributed on the outer periphery of the wire clamping fixture 31. The first wire clamping ear 311, the second wire clamping ear 312, and the third wire clamping ear 313 are used to clamp different cables to constrain the outer conductor 102 and the inner core 103 of the cable, so that the welding point between the cable and the feed plate 104 remains in a fixed position.

[0044] Specifically, such as Figure 6As shown, the first wire clamping ear 311 is located on one side of the wire clamping fixture 31 and clamps onto the cable on the corresponding side; the second wire clamping ear 312 is located on the other side of the wire clamping fixture 31 and clamps onto the cable on the other corresponding side; the third wire clamping ear 313 is located between the first wire clamping ear 311 and the second wire clamping ear 312, and is directly opposite the intersection of the two cables stacked vertically. When the wire clamping fixture 31 is closed on the limiting tray 21 and is clamped by the first magnetic suction member 22 and the second magnetic suction member 32, the first wire clamping ear 311 and the second wire clamping ear 312 press down on the cables on the corresponding sides, and the third wire clamping ear 313 presses down on the intersection of the two cables, so that the cables stacked vertically at the intersection are kept in a fixed relative position, thereby ensuring that the welding point of the cable core 103 and the feed plate 104 does not shift.

[0045] It is understandable that by using the third clamping lug 313 to centrally press the crossover point of the crossover cable, it is possible to effectively prevent the crossover cable from becoming misaligned or loose during the soldering and reflow soldering process, thereby ensuring that the soldering point of the cable core 103 and the feed plate 104 does not shift, and ensuring the stability of the intermodulation performance of the RF product.

[0046] In a preferred embodiment, the wire clamping fixture 31 is made of a high-temperature resistant insulating material, such as a high-temperature resistant engineering plastic, ceramic, or composite material, to avoid short circuits or scratches with the cable and vibrator.

[0047] Specifically, in this embodiment, a ventilation hole 315 is provided in the center of the crimping fixture 31, and the ventilation hole 315 extends vertically through the crimping fixture 31. The ventilation hole 315 can be located in the central area of ​​the crimping fixture 31, and is situated at the center between the first crimping lug 311, the second crimping lug 312, and the third crimping lug 313. The high-temperature hot air from reflow soldering can pass through the ventilation hole 315 and act on the welding point, ensuring uniform heating of the welding position. Simultaneously, the ventilation hole 315 can also reduce the weight of the crimping fixture 31. The ventilation hole 315 can be a circular hole, a square hole, etc.

[0048] Specifically, in this embodiment, the first magnetic suction component 22 and the second magnetic suction component 32 are high-temperature resistant magnets. It is understood that the wire clamping fixture 31 is clamped by magnetic attraction, eliminating the need for screws or mechanical locking clips; mechanical jamming will not occur under the high-temperature conditions of reflow soldering, and the workpiece can be removed by simply lifting the wire clamping fixture 31 upwards after processing. Preferably, the high-temperature resistant magnets can be samarium cobalt magnets or alnico magnets to adapt to high-temperature environments.

[0049] Specifically, in this embodiment, the carrier assembly 20 further includes a sensing positioning piece 23, which is installed on the side of the limiting tray 21 for use by the automated workstation sensor to identify the tooling position and adapt to the automated production line flow. When the entire tooling is transferred to the soldering station, the sensing positioning piece 23 triggers the workstation sensor, which outputs a positioning signal. The soldering equipment then confirms that the tooling is in place and starts the soldering operation.

[0050] The assembly method of a dual-purpose die-cast oscillator tinning and reflow soldering fixture proposed in this embodiment of the invention is as follows: The die-cast oscillator assembly 10 is placed inside the oscillator limiting hole group 211 of the limiting tray 21 to complete the limiting placement of the oscillator body 101; the outer conductor 102 and inner core 103 of the cable are aligned with the welding position of the feeder plate 104; the cable positioning assembly 30 is placed above the limiting tray 21, and the second magnetic suction member 32 of the wire clamping fixture 31 and the first magnetic suction member 22 of the limiting tray 21 are magnetically attracted to each other; the first wire clamping ear 311, the second wire clamping ear 312, and the third wire clamping ear 313 respectively clamp the corresponding cables on the die-cast oscillator assembly 10, thereby fixing the position of the die-cast oscillator assembly 10. Due to the magnetic attraction method, the clamping fixture 31 is very convenient to close and remove, requiring no tools, and will not jam due to high temperature.

[0051] After assembly, the entire tooling is transferred to the soldering station. The induction positioning plate 23 on the side of the limiting tray 21 is used for equipment induction positioning. Soldering is performed on the feeder plate 104. After the soldering process is completed, the entire tooling does not need to be disassembled and is directly transported into the reflow oven. The reflow hot air flows through the hollow slot group 212 of the limiting tray 21 and the ventilation hole 315 of the wire pressing tool 31 to heat the welding position and complete the reflow soldering. After the reflow soldering is completed, the cable positioning component 30 is lifted directly upwards. The wire pressing tool 31 can be removed by overcoming the magnetic attraction force, and the die-cast oscillator component 10 can be taken out.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
