Description

Technical Field

[0001] The present invention belongs to the technical field related to antenna welding, and in particular relates to a device for fixing an antenna and a rotary laser welding device. Background Art

[0002] With the rapid advancement of technology, increasingly stringent requirements are being placed on antenna design and manufacturing processes, particularly in terms of high precision, high reliability, and miniaturization. Antenna manufacturing often requires welding to connect antenna components. Existing welding techniques include resistance welding, arc welding, and laser welding. As antenna manufacturing demands increasingly high precision, high performance, and low-distortion welding, laser welding technology has gradually become a hot topic in welding research.

[0003] In existing laser welding technology, laser welding is usually completed fully automatically and involves rotating the antenna to enable fully automatic welding of multiple parts of the antenna. When welding some antennas, welding ears are usually provided, and the welding ears are also provided on both sides of the antenna. Therefore, the laser equipment needs to rotate and flip so that the laser equipment can weld the welding ears on both sides. During the above-mentioned large movements, since the welding ears of the antenna are usually thin metal sheets, they are not only difficult to clamp, but excessive stress can also cause the metal sheets to be damaged and fall off. Especially when the antenna is rotated as a whole, the welding ears will also have problems such as unstable displacement, so that the yield rate is very low when high-precision antenna production welding is carried out. At the same time, the existing fixed antenna device will make it inconvenient to remove the antenna after the antenna welding is completed, resulting in low production efficiency. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes a device for fixing the antenna and a rotary laser welding device. The device for fixing the antenna is provided with an elastic component in the device to fix the welding ear, so that the antenna welding ear is squeezed and fixed by the elastic component, and when the antenna is disassembled, the elastic component can rebound and be easily removed, thereby avoiding damage to the welding ear.

[0058] Example 1:

[0059] like Figures 1 to 3 As shown, this embodiment provides a device for fixing an antenna, including:

[0060] The first cover plate assembly includes a first cover plate 1, a clamping groove 12 is provided in the first direction x of the first cover plate 1, and a first elastic component 114 is provided in the clamping groove 12. The first cover plate 1 is also provided with a first stopper 17 in the first direction x;

[0061] The second cover plate assembly includes a second cover plate 2 , and a second stopper 21 is provided on the second cover plate 2 in a first direction x;

[0062] By pressing the first cover assembly and the second cover assembly together, the first limiting member 17 and the second limiting member 21 are pressed against each other, so that the first elastic member 114 presses the welding ear 72 of the clip antenna 7 .

[0063] Specifically, the first cover plate assembly is provided with a first cover plate 1, which is provided with a snap-fitting groove 12 in the first direction x. When there are welding ears 72 on both sides of the antenna 7, the first cover plate 1 is provided with snap-fitting grooves 12 on both sides of the first direction x to snap-fit and secure the welding ears 72 on both sides. A first elastic component 114 is provided in the snap-fitting groove 12. Generally, the elastic direction of the first elastic component 114 is a second direction y perpendicular to the first direction x. The first elastic component 114 is typically a spring and a limit block 117. The limit block 117 can be configured according to the shape of the welding ear 72 to avoid stress extrusion. At the same time, a first limiter 17 is also provided in the first direction x. The first limiter 17 is used for snapping and extrusion. When the first limiter 17 is configured, the coordination with the first elastic component 114 needs to be considered. At the same time, a second limiting member 21 is provided in the first direction x of the second cover plate 2. The second limiting member 21 needs to be used with the first limiting member 17. Therefore, when the first limiting member 17 and the second limiting member 21 are provided, their vertical projections partially overlap, so that when pressed together, the two members experience mutual alignment stress extrusion, thereby causing the limiting member to clamp the welding ear 72 of the antenna 7. In this embodiment, the first limiting member 17 is provided on the first elastic component 114 and is movably provided, so that when the first limiting member 17 and the second limiting member 21 are squeezed against each other, as shown in FIG. Figure 3 As shown, the spring of the first elastic component 114 is compressed, causing the stopper 117 connected to one end of the spring to shift and engage the welding lug 72 in the engaging groove 12. This also allows the second stopper 21 to function as the stopper 117. When the first stopper 17 and the second stopper 21 are pressed against each other, the second stopper 21 presses and engages the welding lug 72 of the antenna 7. After welding is completed, the first and second cover plates 1 and 2 are separated, and the first stopper 17 and the second stopper 21 are also separated. At this point, the first elastic component 114 returns to its original position, releasing the welding lug 72 of the antenna 7, facilitating removal of the welding lug 72 and, consequently, allowing the antenna 7 to be easily removed from the fixture.

[0064] It should be noted that the first cover plate 1 and the second cover plate 2 can be closed by external pneumatic mechanical pressing or by mechanical structure buckling.

[0065] In another embodiment, the first stopper 17 and the second stopper 21 can be interlocked to achieve the effect of interlocking the first cover plate 1 and the second cover plate 2. The second stopper 21 can be connected to the second cover plate 2 via a spring to reduce the stress when the second stopper 21 and the first stopper 17 are squeezed against each other, thereby avoiding damage to the mechanical structure.

[0066] The first cover assembly includes a first cover 1, a snap-fit groove 12 disposed in a first direction x of the first cover 1, a first elastic component 114 disposed within the snap-fit groove 12, and a first stopper 17 disposed in the first direction x of the first cover 1; and a second cover assembly includes a second cover 2, a second stopper 21 disposed in the first direction x of the second cover 2. The first and second cover assemblies are pressed together, and the first stopper 17 and the second stopper 21 are pressed against each other, so that the first elastic component 114 presses and engages the welding lug 72 of the antenna 7. When the first stopper 17 and the second stopper 21 are pressed against each other, the first elastic component 114 is pressed against the welding lug 72, thereby engaging the welding lug 72. The engagement of the first elastic component 114 prevents displacement of the welding lug 72, reduces stress during engagement, and prevents damage to the welding lug 72. Furthermore, after welding is completed, the first elastic component 114 automatically rebounds, allowing for easy removal of the antenna 7.

[0067] Example 2:

[0068] In reference Figures 1 to 3 On the basis of Figures 4 to 7 As shown, this embodiment further optimizes and illustrates the device for fixing an antenna proposed in Embodiment 1, with the following differences:

[0069] In some embodiments, a connecting block 3 and a buckling block 4 are provided in a second direction y perpendicular to the first direction x. One end of the connecting block 3 is provided on a first side edge 115 of the first cover plate 1 in the second direction y, and the other end is rotated and provided on a second side edge 22 of the second cover plate 2 in the second direction y.

[0070] One end of the buckling block 4 is movably disposed on the third side 116 of the first cover plate 1 in the second direction y, and the other end is clamped on the fourth side 23 of the second cover plate 2 in the second direction y.

[0071] Specifically, a connecting block 3 and a snap-fit block 4 are provided in a second direction y perpendicular to the first direction x, for snapping the first cover plate 1 and the second cover plate 2 together. The connecting block 3 and the snap-fit block 4 are provided on two sides of the second direction y. For example, when the first cover plate 1 and the second cover plate 2 are rectangular, the connecting block 3 and the snap-fit block 4 are provided on two opposing sides, namely the first side 115 and the second side 22, respectively, to ensure more uniform snap-fit pressure and avoid inconsistent pressure in some areas. The connecting block 3 maintains one side of the first cover plate 1 and the second cover plate 2 connected to each other, and the snap-fit block 4 further enables the snap-fit and separation of the first cover plate 1 and the second cover plate 2. This method allows for simple mechanical snap-fitting without the need for additional pneumatic structure for pressing, thus avoiding stress damage to the antenna 7 caused by misalignment. The connecting block 3 allows the first and second cover plate assemblies to be rotatably connected, and the snap-fit block 4 allows the first and second cover plate assemblies to be snapped and separated, thereby achieving mutual compression of the first and second cover plate assemblies.

[0072] In some embodiments, a first fixing hole 31 is provided at one end of the connecting block 3, and the first fixing hole 31 is fixed to the second side 22 through a first fixing block 32. A first through hole 33 is provided at an end of the connecting block 3 away from the first fixing hole 31, and a first fixing shaft is provided on the first side 115. The first fixing shaft passes through the first through hole 33 so that the connecting block 3 is rotatably set on the second side 22.

[0073] Specifically, the connecting block 3 is provided with a first fixing hole 31 at one end. The first fixing hole 31 is secured to the first side 115 via a first fixing block 32. The first fixing block 32 may be a bolt secured to the first side 115. The above method is only one embodiment; an L-shaped metal sheet can also be used for fixing, allowing the connecting block 3 and the second cover plate 2 to be folded. A first through hole 33 is provided at the other end of the connecting block 3, away from the first fixing hole 31. The first through hole 33 is oriented perpendicular to the direction of the first fixing hole 31. The first fixing hole 31 is generally oriented in a first direction x, while the second through hole 44 is oriented in a second direction y. A first fixing axis is provided in the second direction y and passes through the first through hole 33, allowing the other end of the connecting block 3 to be pivoted about the first fixing axis, allowing the first cover plate 1 and the second cover plate 2 to rotate and overlap. It should be noted that the connection method between the connecting block 3 and the first and second cover plates 1 and 2 can be reversed; it is sufficient to ensure that the first cover plate 1 can rotate along one side to overlap the second cover plate 2. The first cover plate 1 and the second cover plate 2 are connected on one side by fixing the connecting block 3 for press-fitting.

[0074] In some embodiments, a second fixing hole 41 is provided at one end of the snap-fit block 4, and the second fixing hole 41 is fixed to the third side 116 through the second fixing block. The snap-fit block 4 is provided with a snap-fit structure 43, and a second through hole 44 is provided between the snap-fit structure 43 and the second fixing hole 41. The fourth side 23 is provided with a second fixed axis 24 and a third fixed axis, and the second fixed axis 24 is provided through the second through hole 44, and the snap-fit structure 43 is snapped on the third fixed axis.

[0075] Specifically, a second fixing hole 41 is provided at one end of the snap-fit block 4, which is secured to the third side 116 by the second fixing block. The second fixing block can be a bolt, and the snap-fit block 4 is provided with a snap-fit structure 43. The snap-fit structure 43 can be similar to a fishhook structure to enable the structure to engage the third fixed axis and, through this structure, achieve the snap-fit and separation of the first cover plate 1 and the second cover plate 2. The second fixed axis 24 prevents the snap-fit block 4 from disengaging and prevents instability during fixation. The snap-fit block 4 allows the first cover plate 1 and the second cover plate 2 to be snapped together and disassembled, thereby achieving the snap-fit and separation of the antenna 7.

[0076] In some embodiments, the second fixing block is a second elastic component 42 .

[0077] Specifically, the second elastic component 42 includes a spring, one end of which is positioned within the second fixing hole 41 and the other end is fixed to the second cover plate 2. It should be noted that in this embodiment, when the spring is not in the cover, it pulls on the snap-fit block 4, causing the snap-fit structure 43 of the snap-fit block 4 to tilt upward. In the snap-fit state, the tilted snap-fit structure 43 is pressed against the third fixed axis. In this state, the snap-fit block 4 rotates about the second fixed axis 24, pulling on the spring. Once snap-fit is complete, the spring pulls on the snap-fit block 4, causing it to generate a certain pressure in the first direction x, thereby pressing and locking the soldering lug 72 of the antenna 7 in the first direction x.

[0078] The second elastic component 42 rebounds when the first cover plate 1 and the second cover plate 2 to generate an extrusion stress in the first direction x, thereby making the welding ear 72 of the cover and the buckled antenna 7 more secure.

[0079] Example 3:

[0080] Please refer to further Figures 1 to 6 , and further combined with Figures 7 to 9 As shown, based on Example 1 and Example 2, this embodiment also proposes a more specific implementation method, the difference is:

[0081] In some embodiments, the first cover 1 includes a cover body 13 and a sliding slot 14 . The sliding slot 14 is arranged on both sides of the cover body 13 and along the first direction x. A sliding block 18 is arranged in the sliding slot 14 . The width of the sliding block 18 is smaller than that of the sliding slot 14 .

[0082] Specifically, the first cover plate 1 includes a cover plate body 13 and a sliding slot 14. The sliding slots 14 are arranged on both sides of the cover plate body 13 along the first direction x. A sliding block 18 is disposed within the sliding slot 14. The sliding block 18 is the same length as the sliding slot 14 and is smaller in width than the sliding slot 14. The sliding block 18 can move laterally within the sliding slot 14. The snap-fitting slots 12 are arranged in parallel on the sliding slot 14, and the left and right snap-fitting slots 12 are aligned. This ensures that when the antenna 7 is snap-fitted, the left and right welding ears 72 are both disposed within the snap-fitting slots 12 on both sides. The antenna 7 is disposed on the cover plate body 13. The first elastic component 114 is disposed within the engaging groove 12. In this embodiment, more specifically, one end of the first elastic component 114 is disposed on or abuts a side wall of the engaging groove 12 away from the cover body 13, while the other end abuts the cover body 13. The first stopper 17 can be fixed to the sliding block 18 and, through the second stopper 21, is pressed against the sliding block 18, causing the sliding block 18 to move toward the cover body 13 to engage the welding lug 72 and further compress the first elastic component 114. When welding is completed and removed, the second cover 2 and the first cover 1 are separated, and the first elastic component 114 is reset, causing the sliding block 18 to move away from the cover body 13, thereby facilitating the removal of the welding lug 72. Furthermore, when the sliding block 18 is pressed toward the cover body 13, it abuts against the antenna body 71 disposed on the cover body 13, thereby improving the engagement stability of the antenna 7.

[0083] The sliding block 18 slides relatively in the sliding groove 14 to cooperate with the first elastic component 114 . When the first elastic component 114 is engaged, it presses the welding ear 72 of the snap-on antenna 7 .

[0084] In some embodiments, third through holes are provided at both ends of the sliding block 18, and fourth fixed shafts 15 are provided at both ends of the sliding groove 14. The sliding block 18 is connected to the fourth fixed shaft 15 through the third through holes on both sides, and a third elastic component 16 is provided on the fourth fixed shaft 15.

[0085] Specifically, third through holes are provided at both ends of the sliding block 18, and fourth fixed shafts 15 are provided at both ends of the sliding groove 14 so that the sliding block 18 can be fixed in the sliding groove 14 through the fourth fixed shaft 15 to avoid lateral movement, and a third elastic component 16 is provided. The third elastic component 16 can be a spring. The spring is sleeved on the fourth fixed shaft 15 and is arranged between the sliding block 18 and the cover plate body 13 to assist the first elastic component 114 in moving and moving the slider away. Furthermore, the third elastic component 16 can have the effect of shock absorption and stress relief. It should be noted that, in general, the fourth fixed shaft 15 can replace the above-mentioned first fixed shaft and the third fixed shaft, that is, the first through hole 33 of the connecting block 3 is fixed to the first cover plate 1 through the fourth fixed shaft 15, and at the same time, the buckling structure 43 of the buckling block 4 buckles the fourth fixed shaft 15 on the other side to achieve buckling and snap connection.

[0086] The sliding block 18 is provided with a third through hole and a fourth fixed shaft 15 on both sides. The sliding block 18 is set on the fourth fixed shaft 15 set at both ends of the sliding groove 14 through the third through hole, and is provided with a third elastic component 16, which assists in squeezing the welding ear 72 through the third elastic component 16.

[0087] In some embodiments, a snap-in block 111 is provided in the snap-in slot 12, a welding slot 112 is provided in the snap-in block 111, the welding slot 112 is used to set a welding ear 72, a limiting slot 113 is provided in the welding slot 112, and the welding ear 72 is limited by the limiting slot 113 through squeezing by the first elastic component 114.
