[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The disclosure below provides many different embodiments or examples to realize the different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the embodiments of the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0032] In order to solve the problems in the prior art, the present application provides a welding jig and a welding device, which can accurately position the wires and braided parts of the RF antenna, thereby ensuring the quality of welding and improving the yield rate.

[0033] like Figure 1-6 As shown, an embodiment of the present application provides a welding fixture, including: a base 1, having a first positioning groove 11 for positioning a solder pad a and a clamping groove 12 for positioning a radio frequency antenna b; a cover plate 2, movably arranged on the base 1, the cover plate 2 is used to press the solder pad a in the positioning groove, and a second positioning groove 21 is arranged on the cover plate 2, which is used to position the conductor b1 of the radio frequency antenna b at the first welding point a1 of the solder pad a; and a clamping assembly 3, which is arranged on the base 1 and is used to press the positioned radio frequency antenna b.

[0034] In the present application, the pad a is positioned by the first positioning groove 11, and then the pad a is pressed by the cover plate 2, the conductor b1 of the RF antenna b is positioned by the second positioning groove 21 on the cover plate 2, and the clamping groove 12 on the base 1 clamps and positions the wire of the RF antenna b, thereby completing the positioning of the braided portion b2 of the RF antenna b. The wire and the braided portion b2 of the RF antenna b can be accurately positioned, thereby ensuring the quality of welding and improving the yield rate.

[0035] In the related art, when the existing RF antenna b is welded, since the conductor b1 and the braided part b2 of the RF antenna b are respectively welded on the pad a, and the wire of the RF antenna b is made of a bendable material, the existing RF antenna b is often welded manually by holding a soldering iron head, that is, the conductor b1 of the RF antenna b is abutted against the first welding point a1 of the pad a and the welding is completed, and the braided part b2 of the RF antenna b is abutted against the second welding point a2 of the pad a and the welding is completed. The work efficiency is slow, and there is a great deal of uncertainty in manual welding, and it is difficult to ensure that the wire of the RF antenna b is in the center position after welding. It is necessary to manually weld multiple RF antennas b one by one, and the work efficiency is low.

[0036] In the embodiment of the present application, the pad a in the first positioning groove 11 is pressed by the cover plate 2, the conductor b1 of the RF antenna b is positioned by the second positioning groove 21, and the wire of the RF antenna b is clamped and positioned by the clamping groove 12 on the base 1. The braided portion b2 of the RF antenna b is located on the wire and adjacent to the conductor b1. When the wire and the conductor b1 are positioned, the braided portion b2 is positioned together, thereby completing the precise positioning of the conductor b1 and the braided portion b2. Subsequently, the positioned RF antenna b can be automatically welded by a welding machine, and multiple RF antennas b can be placed and positioned with the pad a at one time, and the welding can be completed in sequence by the welding machine, thereby improving work efficiency.

[0037] In some embodiments, the second welding point a2 of the pad a is used to weld the woven portion b2 of the RF antenna b. The second welding point a2 is arranged between the card slot 12 and the second positioning slot 21 and along the straight connecting line between the card slot 12 and the second positioning slot 21.

[0038] In the present application, the second positioning groove 21 of the cover plate 2 positions the conductor b1 of the RF antenna b, the braided portion b2 is arranged on the wire and extends along the axial direction of the wire, and the second welding point a2 is located on the straight line connecting the second positioning groove 21 and the card slot 12. A straight line is determined by two points, which can ensure that the wire of the RF antenna b is arranged along the straight line connecting the second positioning groove 21 and the card slot 12, and the second welding point a2 on the pad a is also arranged along the straight line connecting the second positioning groove 21 and the card slot 12, thereby ensuring that the braided portion b2 of the RF antenna b can be precisely aligned with the second welding point a2 on the pad a, thereby ensuring the positioning accuracy of the braided portion b2.

[0039] The RF antenna b in the present application is mainly used to transmit RF signals. The innermost part is the conductor b1, the outer part of the conductor b1 is the braided layer b2, the outer part of the braided layer b2 is the insulating layer, the insulating layer is removed from the wire, and the inner braided layer b2 is exposed, and then a part of the braided layer b2 is removed, and a certain length of the conductor b1 is exposed.

[0040] Specifically, the conductor b1 and the braided portion b2 of the existing RF antenna b are relatively small. The control of the positioning accuracy during manual welding mainly relies on the worker's eyesight to position the RF antenna b and the pad a, and the welding quality cannot be guaranteed. However, in the embodiment of the present application, as long as the conductor b1 of the RF antenna b is inserted into the second positioning groove 21, the wire of the RF antenna b is inserted into the slot 12 and straightened, the positioning accuracy of the conductor b1 and the braided portion b2 can be guaranteed, thereby ensuring the subsequent welding quality.

[0041] In some embodiments, the positioned conductor b1 and the braided portion b2 are respectively located on two sides of the second positioning groove 21 , and the positioned conductor b1 and the braided portion b2 are respectively adjacent to the second positioning groove 21 .

[0042] In the present application, after the second positioning groove 21 completes the positioning of the conductor b1 of the RF antenna b, the conductor b1 and the braided portion b2 are respectively located on both sides of the second positioning groove 21 and are adjacent to the second positioning groove 21, which can further improve the positioning effect of the conductor b1 and the braided portion b2. The second positioning groove 21 cooperates with the card slot 12 to position the extension direction of the braided portion b2, ensuring that the braided portion b2 of the RF antenna b can be accurately matched with the second welding point a2 on the pad a.

[0043] In some embodiments, the opening of the second positioning groove 21 faces the base 1 .

[0044] In the present application, when the cover plate 2 is pressed against the base 1 and presses the pad a on the base 1, the opening of the second positioning groove 21 faces the base 1, so that the RF antenna b can be fully abutted against the pad a after being positioned by the second positioning groove 21, and it is convenient to remove the cover plate 2 in a direction perpendicular to the surface of the base 1 after the RF antenna b is positioned, so as to carry out subsequent welding operations.

[0045] In some embodiments, the cover plate 2 is provided with an observation hole 22 for observing the positioned conductor b1 .

[0046] In the present application, the cover plate 2 is pressed against the pad a, and the conductor b1 of the RF antenna b is inserted into the second positioning groove 21 to complete the positioning of the conductor b1. At this time, the length of the conductor b1 passing through the second positioning groove 21 can be observed through the observation hole 22 on the cover plate 2. Because the reserved length of the conductor b1 of each RF antenna b is different, it is sufficient to ensure that the conductor b1 of the RF antenna b is just located at the first welding point a1 of the pad a through observation.

[0047] In some embodiments, a positioning hole 23 is provided on the cover plate 2 , and a positioning column 13 is provided on the base 1 . The positioning column 13 can be inserted into the positioning hole 23 to position the cover plate 2 .

[0048] In the present application, the positioning column 13 is inserted into the positioning hole 23 to ensure the accuracy of the cover plate 2 and the base 1, so that after the second positioning groove 21 on the cover plate 2 positions the conductor b1 of the RF antenna b, the conductor b1 of the RF antenna b can be accurately abutted with the first welding point a1 on the pad a, further ensuring the positioning accuracy of the RF antenna b and the pad a. In addition, the positioning column 13 and the positioning hole 23 cooperate to allow the cover plate 2 to be disassembled and assembled along the direction of the positioning column 13 as much as possible. When the cover plate 2 is placed, the surface of the cover plate 2 and the pad a will not slide relative to each other and cause wear on the surface of the pad a. When the cover plate 2 is removed, it is also perpendicular to the surface of the base 1, and the opening of the second positioning groove 21 faces the base 1, so the cover plate 2 will not interfere with or disturb the RF antenna b when it is removed, thereby ensuring the positioning effect of the RF antenna b.

[0049] In some embodiments, at least two positioning posts 13 and positioning holes 23 are provided, and at least two positioning posts 13 are staggered.

[0050] In the present application, the positioning posts 13 are designed in a staggered distribution manner, which can achieve a fool-proof effect and avoid pressure loss on the pad a when the cover plate 2 is placed.

[0051] In some embodiments, the pressing assembly 3 includes a pressing plate 31 , and the pressing plate 31 is rotatably connected to the base 1 .

[0052] In the present application, the pressing plate 31 is rotated to press the wire portion of the RF antenna b. After welding is completed, the pressing plate 31 can be removed by flipping and rotating the pressing plate 31, so that the RF antenna b and the pad a can be removed.

[0053] In some embodiments, a plurality of first positioning grooves 11 are sequentially arranged on the base 1 , and the cover plate 2 is used to press the plurality of pads a in the plurality of first positioning grooves 11 .

[0054] In the present application, multiple pads a can be positioned separately and simultaneously through the multiple first positioning grooves 11 on the base 1, and then the conductors b1 of multiple RF antennas b can be positioned through the multiple second positioning grooves 21 on the cover plate 2, so that the positioning of multiple groups of pads a and RF antennas b can be completed at one time, and then the welding of multiple groups of pads a and RF antennas b can be completed at one time, and the welding of multiple groups of pads a and RF antennas b can be completed by one positioning, thereby improving the processing efficiency.

[0055] The welding jig positions the pad a through the first positioning groove 11, and then presses the pad a through the cover plate 2, and positions the conductor b1 of the RF antenna b through the second positioning groove 21 on the cover plate 2. The clamping groove 12 on the base 1 clamps and positions the wire of the RF antenna b, and then completes the positioning of the braided part b2 of the RF antenna b. The wire and the braided part b2 of the RF antenna b can be accurately positioned, thereby ensuring the quality of welding and improving the yield rate.

[0056] An embodiment of the present application provides a welding device, including: a welding machine; and the above-mentioned welding jig.

[0057] In the present application, after the pad a and the RF antenna b are positioned by a welding jig, they are loaded on a welding machine, and the pad a and the RF antenna b on the welding jig are welded by the welding machine to complete the welding of the conductor b1 and the braided portion b2.

[0058] Specifically, when performing welding operations, firstly, multiple pads a are positioned and loaded into multiple first positioning grooves 11 of the base 1 to complete the positioning of multiple pads a, then the cover plate 2 is covered on the multiple pads a, and the conductor b1 of the RF antenna b is passed through the second positioning groove 21 to position the conductor b1 of the RF antenna b, and then the wire of the RF antenna b is clamped through the clamping groove 12 on the base 1, and the wire is straightened so that the braided portion b2 of the RF antenna b is aligned with the second welding point a2 of the pad a, and the positioning of multiple RF antennas b is completed in the same way, the braided portion b2 and the second welding point a2 are welded and fixed, and the fixing of multiple RF antennas b is completed, and then the cover plate 2 is removed, and then the conductor b1 and the first welding point a1 are welded to complete the welding of multiple RF antennas b, and the welding of multiple pads a and RF antenna b can be completed by only one positioning, thereby improving the processing efficiency. In addition, the positioning accuracy of the pads a and the RF antenna b can be guaranteed, and the welding quality can be guaranteed.
