Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to an automated reflow soldering fixture for oscillators. Background Technology

[0002] In modern wireless communication, radar systems, satellite navigation (such as GPS and BeiDou), and the Internet of Things, key microwave radio frequency components such as dielectric resonators (DRAs), ceramic oscillators, or crystal oscillators play a crucial role. These oscillators typically need to be precisely soldered onto printed circuit boards (PCBs) using a reflow soldering process to achieve electrical connections and mechanical fixation.

[0003] Reflow soldering is a surface mount technology (SMT) that involves melting solder paste and then cooling it to solder components onto PCB pads.

[0004] However, current reflow soldering fixtures for oscillators still have the following shortcomings in practical use: Existing fixture designs are relatively simple, typically only able to clamp one or a few workpieces at a time, and rely on manual operation for oscillator placement and positioning. This not only increases the labor intensity of operators but also becomes a bottleneck in the automated production line process, unable to match high-speed automated pick-and-place machines and reflow ovens, thus restricting the improvement of overall production efficiency and capacity. Furthermore, the electrical performance of the oscillator is highly sensitive to its positional accuracy on the PCB. Ordinary fixtures lack high-precision positioning and limiting mechanisms, making them prone to slight displacement due to vibration or external impact during transfer and soldering, leading to soldering position deviations and affecting key parameters such as the frequency of the final product. Utility Model Content

[0005] Given that existing fixture designs are relatively simple, typically only able to clamp one or a few workpieces at a time, and relying on manual operation for picking up, placing, and positioning the oscillator, this not only increases the labor intensity of operators but also becomes a bottleneck in the automated production line process. It cannot be matched with high-speed automated pick-and-place machines and reflow ovens, restricting the improvement of overall production efficiency and capacity. Furthermore, the electrical performance of the oscillator is highly sensitive to its positional accuracy on the PCB. Ordinary fixtures lack high-precision positioning and limiting mechanisms, making them prone to slight displacement due to vibration or external impact during transfer and soldering, leading to soldering position deviations and affecting key parameters such as the frequency of the final product. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an automated reflow soldering fixture for oscillators. The purpose is to enable multiple sets of oscillators to be clamped and welded at the same time by setting multiple limiting grooves on the fixture, which completely changes the inefficient mode of traditional one-on-one clamping and welding. Moreover, this design is perfectly matched with the rhythm of automated production lines and can be seamlessly integrated with automatic feeding robots, conveyor belts and reflow ovens, realizing full automation of the oscillator welding process, eliminating the efficiency bottleneck caused by manual operation, and greatly improving production capacity.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automated reflow soldering fixture for an oscillator, including a base plate, a top plate disposed above the base plate, eight sets of columns disposed between the base plate and the top plate, nine sets of first rectangular grooves disposed on the top of the base plate, wherein the first rectangular grooves penetrate the first arc-shaped groove, and nine sets of second rectangular grooves disposed on the top of the top plate, wherein the second rectangular grooves penetrate the top plate, wherein each set of second rectangular grooves corresponds to each set of first rectangular grooves.

[0008] As a preferred embodiment of the oscillator automated reflow soldering fixture of this utility model, four sets of insertion holes are provided at the four corners and the middle position of the top of the base plate, and the insertion holes penetrate the base plate.

[0009] As a preferred embodiment of the oscillator automated reflow soldering fixture of this utility model, the bottom end of the column is provided with a positioning post, and the bottom end of the positioning post extends to the inside of the insertion hole.

[0010] As a preferred embodiment of the oscillator automated reflow welding fixture of this utility model, the top of the column is provided with a first connecting hole, and four sets of second connecting holes are provided at the four corners and the middle position of the top of the top plate, and the second connecting holes penetrate the top plate, and each set of second connecting holes corresponds to the first connecting hole at the top of the column.

[0011] As a preferred embodiment of the oscillator automated reflow soldering fixture of this utility model, wherein: a first arc-shaped groove is provided at both ends and both sides of the inner side of the first rectangular groove, and the first arc-shaped groove and the inner side of the first rectangular groove are interconnected.

[0012] As a preferred embodiment of the oscillator automated reflow soldering fixture of this utility model, a limiting groove is provided at both ends of the inner side of the second rectangular groove and at the top of both sides, and the limiting groove is located at the top of the top plate.

[0013] As a preferred embodiment of the oscillator automated reflow soldering fixture of this utility model, wherein: a second arc-shaped groove is provided at both ends of the inner side of the second rectangular groove and at the top of both sides, and the inner sides of the second arc-shaped groove and the second rectangular groove are interconnected, and the diameter of the second arc-shaped groove is larger than that of the first arc-shaped groove.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. This utility model, through the nine sets of second rectangular slots set on the top plate of the fixture, enables multiple sets of vibrators to be clamped and welded at the same time, which completely changes the inefficient mode of traditional one-on-one clamping and welding. Moreover, this design perfectly matches the rhythm of automated production lines and can be seamlessly integrated with automatic feeding robots, conveyor belts and reflow ovens, realizing full automation of the vibrator welding process, eliminating the efficiency bottleneck caused by manual operation, and greatly improving production capacity.

[0016] 2. This utility model provides a limiting groove on the inner side wall of the second rectangular groove, so that the shape of the second rectangular groove precisely matches the edge contour of the vibrator, which plays a natural role in preventing errors. This ensures that only the vibrator with the correct orientation can be placed in the groove, fundamentally avoiding batch scrap caused by manual incorrect placement. At the same time, the matching limiting groove can firmly restrict the vibrator in the preset position, ensuring that the clamping force and thermal stress distribution of each vibrator is highly uniform during the welding process. This effectively prevents defects such as incomplete welding, cold welding, or voids in the weld joint caused by uneven pressure. Attached Figure Description

The fixture includes a base plate 1, a top plate 2 disposed above the base plate 1, eight sets of columns 4 disposed between the base plate 1 and the top plate 2, which connect the base plate 1 and the top plate 2, nine sets of first rectangular grooves 8 disposed on the top of the base plate 1, the first rectangular grooves 8 penetrating the first arc-shaped grooves 9, and nine sets of second rectangular grooves 10 disposed on the top of the top plate 2, the second rectangular grooves 10 penetrating the top plate 2. Each set of second rectangular grooves 10 corresponds to each set of first rectangular grooves 8.

[0028] Four sets of insertion holes 3 are provided at the four corners and the middle of the top of the base plate 1, and the insertion holes 3 penetrate the base plate 1. The bottom end of the column 4 is provided with a positioning post 5, and the bottom end of the positioning post 5 extends to the inside of the insertion hole 3. Through the setting of the positioning post 5 on the column 4, it can be matched with the insertion hole 3 on the base plate 1, so as to fix the column 4 on the base plate 1.

[0029] The top of the column 4 is provided with a first connecting hole 6, and four sets of second connecting holes 7 are provided at the four corners and the middle position of the top of the top plate 2. The second connecting holes 7 penetrate the top plate 2, and each set of second connecting holes 7 corresponds to the first connecting hole 6 at the top of the column 4.

[0030] The first rectangular groove 8 has first arc-shaped grooves 9 at both ends and on both sides of its inner side, and the first arc-shaped grooves 9 and the inner sides of the first rectangular groove 8 are interconnected.

[0031] Limiting grooves 11 are provided at both ends of the inner side of the second rectangular groove 10 and at the top of both sides. The limiting grooves 11 are located at the top of the top plate 2. The setting of the limiting grooves 11 makes it easier to limit the edge of the oscillator.
