[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution:

[0026] Example 1: A welding fixture for a T / R module substrate, comprising: substrate body 2.

[0027] Specifically, elastic clamping plates 4 are provided on the outer sides of both ends of the substrate body 2. The elastic clamping plates 4 are horizontally placed in a "U" shape, and the two elastic clamping plates 4 are symmetrically distributed. The elastic clamping plates 4 are made of a rigid material that can undergo elastic deformation. When the elastic clamping plates 4 elastically deform, they can change their opening size. Strip clamping plates 5 are fixed to the inner walls of both ends of the elastic clamping plates 4, and the two strip clamping plates 5 clamp the edges of the substrate body 2 from the upper and lower sides, respectively. Figure 6As shown, by pressing the edge of the substrate body 2 between the two strip clamps 5, the two strip clamps 5 can be spread apart. At this time, the elasticity of the elastic clamp 4 itself can ensure that the two strip clamps 5 clamp and position the substrate body 2 from the upper and lower sides of the substrate body 2 respectively.

[0028] Secondly, a self-fixing strip-shaped airbag 7 is provided in the inner cavity of the elastic clamp 4, and the air pressure inside the strip-shaped airbag 7 is greater than the external atmospheric pressure. The strip-shaped airbag 7 is pre-filled with gas, and the strip-shaped airbag 7 is kept in an inflated state. Multiple side top plates 8 are fixed along the length of one side of the surface of the strip-shaped airbag 7 at equal intervals. The strip-shaped clamp 5 has clearance grooves 51 corresponding to the side top plates 8 inside. Figure 6 As shown, the side top plate 8 can move a certain distance left and right in the horizontal direction. The side top plate 8 is located at the edge of the substrate body 2, and the side top plate 8 is inserted into the groove at the edge of the substrate body 2. Figure 2 As shown, the edge of the substrate body 2 has multiple irregular grooves. When the edge of the substrate body 2 is located between two strip clamps 5, the edge of the substrate body 2 and the side top plate 8 are pressed against each other. The side top plate 8 is subjected to the expansion of the strip airbag 7. Therefore, a portion of the side top plates 8 corresponding to the grooves at the edge of the substrate body 2 can be inserted into the grooves, thereby achieving the positioning of the substrate body 2 and preventing the substrate body 2 from shifting position.

[0029] To facilitate the insertion of the substrate body 2 between the two strip clamps 5, the two strip clamps 5 are inclined on their sides that are close to each other, and a clamping groove 53 is formed between the two strip clamps 5. The corners of the strip clamps 5 are rounded. Therefore, when the substrate body 2 is inserted from the outside of the clamping groove 53 into the inner cavity of the clamping groove 53, the inclined surfaces of the substrate body 2 and the strip clamps 5 press against each other, which can automatically open the two strip clamps 5, thereby realizing the automatic clamping of the substrate body 2 by the two strip clamps 5.

[0030] To connect the strip clamping plate 5 and the elastic clamping plate 4, this application further includes studs 52 fixed on opposite sides of the two strip clamping plates 5. A positioning hole 41 corresponding to the stud 52 is provided through the surface of the elastic clamping plate 4. The stud 52 moves through the positioning hole 41 and is tightened with a nut. Figure 4 As shown, the strip clamp 5 and the elastic clamp 4 are fixedly connected to each other by studs 52 and nuts, which facilitates the installation, disassembly, maintenance and replacement of the strip clamp 5.

[0031] To position the strip-shaped airbag 7, the present application further has a guide plate 6 fixedly connected to the inner wall of the middle part of the elastic splint 4. The guide plate 6 is horizontally placed in a "U" shape, and the guide plate 6 covers the other side of the surface of the strip-shaped airbag 7, and the strip-shaped airbag 7 is adhesively fixed to the guide plate 6. As Figure 4 and Figure 6 shown, the guide plate 6 itself is made of a rigid material that does not undergo elastic deformation. The setting of the guide plate 6 is mainly used to install and fix the strip-shaped airbag 7.

[0032] To prevent the side top plate 8 from tilting itself, the two ends of the guide plate 6 of the present application respectively correspond to the two strip-shaped splints 5. The side top plate 8 is horizontally placed in a "T" shape, and the upper and lower ends of the side top plate 8 respectively fit the upper and lower inner walls of the guide plate 6. As Figure 6 shown, the cooperation of the guide plate 6 and the avoidance groove 51 can guide the sliding direction of the side top plate 8, so that the side top plate 8 can only slide left and right in the horizontal direction, thereby preventing the side top plate 8 from tilting and deflecting when it is squeezed by the edge of the substrate body 2.

[0033] To fixedly connect the guide plate 6 to the elastic splint 4, the present application further has a mounting seat 3 fixed to the outer wall of the middle part of the elastic splint 4. A positioning hole 32 is penetrated through the side wall of the mounting seat 3. A stud 61 is fixed to the surface of the guide plate 6. The stud 61 movably penetrates through the positioning hole 32 and is tightened by a nut. The setting of the mounting seat 3 is mainly used to fixedly connect the guide plate 6 to the elastic splint 4, so as to realize the relative fixation between the strip-shaped airbag 7 and the elastic splint 4.

[0034] To flip the substrate body 2, the present application further has a "C"-shaped flipping frame 1 provided on the outer side of the substrate body 2. Installation grooves 11 are opened at both ends of the flipping frame 1. A clamping groove 31 is opened on the surface of the mounting seat 3. The mounting seat 3 is clamped and installed in the inner cavity of the installation groove 11 through the clamping groove 31. A clamping plate 12 is buckled at the end of the flipping frame 1. A rotating shaft 13 is fixedly connected to the middle of the flipping frame 1. The rotating shaft 13 itself is installed on an external fixed cross beam. By installing the elastic splint 4 at the end of the flipping frame 1, this device ensures that the flipping frame 1 can turn over the substrate body 2 when flipping, so as to facilitate double-sided welding of the substrate body 2. In addition, it should be noted that the flipping frame 1 can also be provided with a telescopic rod structure known in the prior art at its middle position to change the distance between the two elastic splints 4, so as to adapt to substrate bodies 2 of different sizes. Since this design is not the main discussion content of the present application, it will not be elaborated here.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
