[0026] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0027] Reference Figure 1-2 , Figure 1This is a schematic diagram of the structure of the circuit board flip welding fixture in the embodiment. Figure 2 The schematic diagram of the structure of the circuit board flip welding fixture carrying the circuit board in the embodiment is shown in FIG. The circuit board flip welding fixture in the embodiment includes a bearing assembly 1, a flip assembly 2 and a fixture assembly 3. The bearing assembly 1 includes a bearing member 11 and two support members 12 respectively arranged on the bearing member 11. The flip assembly 2 is arranged on the bearing member 11 and is located between the two support members 12. The fixture assembly 3 includes a fixture member 31 and a fixing member 32. One end of the fixture member 31 is rotatably connected to the flip assembly 2. The length of the fixture member 31 is greater than the distance between the flip assembly 2 and any support member 12. Any support member 12 can support the fixture member 31 and allow space between the fixture member 31 and the surface of the bearing member 11. The fixture member 31 is provided with a first welding opening 311. The fixing member 32 is movablely covered on the fixture member 31. The fixing member 32 is provided with a second welding opening 321. The other end of the clamp member 31 is supported on a support member 12, the circuit board 100 is placed on one side of the clamp member 31, the fixing member 32 covers the circuit board 100, and one side of the circuit board 100 is welded through the second welding port 321. The clamp member 31 is flipped with the flip assembly 2 as the flip axis, driving the circuit board 100 to flip synchronously. Another support member 12 supports the clamp member 31, and welding is performed on the other side of the circuit board 100 through the first welding port 311.

[0028] The circuit board flip welding fixture in this embodiment is placed on a welding workbench for use, and is specifically used to clamp the circuit board 100 so that it can be welded on the circuit board flip welding fixture. When the circuit board 100 is placed on the fixture 31, one side of the circuit board 100 can be welded through the second welding port 321. Through the setting of the flip assembly 2, after welding one side of the circuit board 100, the fixture 31 and the circuit board 100 can be flipped, and the components can be welded on the other side of the circuit board 100 through the first welding port 311. In this way, the double-sided welding of the circuit board 100 can be achieved, and the welding efficiency is improved. At the same time, since there is a space between the fixture 31 and the surface of the carrier 11, the components welded on one side of the circuit board 100 are all located in the space, avoiding direct contact with the carrier 11, thereby avoiding damage to the components and improving the welding quality of the product.

[0029] Re-reference Figure 1-2Preferably, the flip assembly 2 includes a flip member 21 and a rotating shaft member 22. The flip member 21 is disposed on the bearing member 11 and is located between the two supporting members 12. The rotating shaft member 22 is rotatably disposed on the flip member 21. One end of the clamp member 31 is fixedly connected to the rotating shaft member 22. Through the arrangement of the rotating shaft member 22, the clamp member 31 can be flipped with the rotating shaft member 22 as the flip axis, thereby driving the circuit board 100 carried on the clamp member 31 to flip synchronously, so that the circuit board 100 can be changed from a state where one side faces up to a state where the other side faces up, which is convenient for workers to solder components on both sides of the circuit board 100, thereby realizing double-sided soldering and improving soldering efficiency. Specifically, the rotating shaft member 22 includes a rotating shaft and a connecting plate. The rotating shaft is rotatably disposed on the flip member 21. The connecting plate is fixedly disposed on the side of the rotating shaft. One end of the clamp member 31 is fixedly connected to the connecting plate. The connecting plate also plays a role in assisting the support of the clamp member 31.

[0030] Re-reference Figure 1-2 Preferably, there are two flipping members 21, and the two flipping members 21 are respectively arranged on the bearing member 11. The two ends of the rotating shaft member 22 are respectively connected to the two flipping members 21 for rotation, and the connection line of the two flipping members 21 is perpendicular to the connection line of the two supporting members 12. In specific applications, the bearing member 11 is a bearing plate, which is rectangular in shape. The two supporting members 12 are respectively close to the two short sides of the bearing plate, and the two flipping members 21 are respectively close to the two long sides of the bearing plate. The two flipping members 21 arranged on both sides of the bearing plate make the rotation of the rotating shaft member 22 more stable, which is equivalent to providing two force points for the flipping action of the clamp member 31, thereby improving the smoothness and stability of the flipping of the clamp member 31. Specifically, the flipping member 21 is a flipping block, which is provided with a rotation hole, and the two ends of the rotating shaft member 22 are respectively rotatably arranged in the two rotation holes.

[0031] Refer to Figure 3-4 , Figure 3 is another structural schematic diagram of a circuit board flip welding fixture carrying a circuit board in an embodiment, Figure 4Schematic diagram of the structure of the circuit board flip welding fixture after flipping in the embodiment, preferably, the fixing member 32 includes a fixing portion 322 and a locking portion 323, the locking portion 323 is arranged on one side of the fixture member 31, the fixing portion 322 is rotatably arranged on the other side of the fixture member 31, the movable end of the fixing portion 322 can be covered on the fixture member 31, and the locking portion 323 locks the movable end of the fixing portion 322 to the fixture member 31. The second welding port 321 is opened in the fixing portion 322. In specific applications, in order to facilitate distinction, in this embodiment, the side of the clamp member 31 covered by the fixing portion 322 becomes the front side of the clamp member 31, and the other side becomes the back side of the clamp member 31, that is, the fixing portion 32 in this embodiment is movably covered on the front side of the clamp member 31. Through the arrangement of the fixing portion 322 and the locking portion 323, when the circuit board 100 is placed on the front side of the clamp member 31, the fixing portion 322 covers the circuit board 100, so that the circuit board 100 is placed flatly on the front side of the clamp member 31. At this time, the locking portion 323 locks the movable end of the fixing portion 322, so that the circuit board 100 is pressed firmly between the fixing portion 322 and the clamp member 31, ensuring that the circuit board 100 does not shake during the subsequent welding process of components, ensuring the stability and accuracy of component welding, and improving the welding quality. Specifically, the locking portion 323 includes a locking body and two locking blocks. The locking body is arranged on one side edge of the front side of the clamp member 31, and the two locking blocks are rotatably arranged on the locking body. When the fixing portion 322 is covered on the circuit board 100, the locking block is rotated to protrude relative to the locking body. The protruding portion contacts the movable end of the fixing portion 322 and is located above the movable end, so that the movable end of the fixing portion 322 is pressed between the locking block and the circuit board 100, thereby achieving the effect of locking the fixing portion 322.

[0032] Re-reference Figure 1-4Preferably, the fixing portion 322 is detachably connected to the clamp member 31. In specific applications, since the second welding port 321 is provided on the fixing portion 322, when another batch of circuit boards 100 is replaced for welding, the fixing portion 322 can be disassembled and replaced with a fixing portion 322 adapted to the circuit board 100, that is, the fixing portion 322 with a second welding port 321 of a different shape is replaced, so that the second welding port 321 is directly opposite to the component welding area on the circuit board 100, which is convenient for welding components of circuit boards 100 of different batches or with different welding areas, thereby broadening the scope of application of this embodiment. Specifically, the fixing portion 322 includes a fixing body and a fixing cover plate, the fixing body is provided on a side of the front of the clamp member 31 away from the locking body, one end of the fixing cover plate is rotatably connected to the fixing body, and the other end can be movably covered on the clamp member 31, and the second welding port 321 is provided on the fixing cover plate. In short, a welding area is formed on the circuit board 100 through the second welding port 321, which makes it easier for workers to accurately weld components in the welding area, thereby improving welding efficiency. At the same time, the remaining area of ​​the circuit board 100 except the welding area is covered and protected by the fixed cover plate, ensuring that other areas of the circuit board are not affected by the welding operation during the welding process, thereby avoiding damage to other areas of the circuit board 100.

[0033] Re-reference Figure 1-4 Preferably, when any support member 12 supports the clamp member 31, the clamp member 31 is parallel to the carrier 11. In specific applications, the clamp member 31 is a clamp plate, on which a first welding port 311 is provided, and the support member 12 is a support block. When the front side of the clamp member 31 is facing upward, the other end of the clamp member 31 is supported on one of the supports 12, and when the back side of the clamp member 31 is facing upward, the fixing portion 22 of the clamp member 31 is supported on the other support member 12 after flipping, that is, the height of one of the supports 12 is higher than that of the other support member 12. It should be particularly noted that no matter which support member 12 supports the clamp member 31, the clamp member 31 and the carrier 11 are in a parallel state, that is, the circuit board 100 and the carrier 11 remain in a parallel state, ensuring that the circuit board 100 is in a horizontal state when double-sided welding is performed, thereby improving the welding quality of components.

[0034] Re-reference Figure 1-4 Preferably, the clamp 31 and the fixing member 32 are both made of insulating materials. When the circuit board 100 is fixed and components are welded, the clamp 31 and the fixing member 32 made of insulating materials can effectively prevent the circuit board 100 from short circuiting and being burned by static electricity, reduce the probability of product damage, and protect welding workers from electric shock, thereby improving safety.

[0035] Re-reference Figure 1-4Preferably, the fixture assembly 3 also includes at least two positioning members 33, the two positioning members 33 are arranged on the fixture member 31 and are respectively in contact with the diagonal positions of the circuit board 100, and the two positioning members 33 position and carry the circuit board 100 on the fixture member 31. Through the arrangement of the positioning members 33, a positioning and carrying position of the circuit board 100 is essentially formed on the fixture member 31. When the circuit board 100 is placed on the fixture member 31, the two positioning members 33 are respectively in contact with the diagonal positions of the circuit board 100, so that the circuit board 100 is limited on the fixture member 31, ensuring that the circuit board 100 does not shake during the component welding process, improving the accuracy of component welding, and improving product quality. Specifically, in this embodiment, the number of positioning members 33 is two, and the two positioning members 33 are respectively arranged at the diagonal positions of the fixture member 31. Of course, in other embodiments, the number of positioning members 33 can be three, four or more, and they only need to cooperate together to form a limited bearing position for the circuit board 100, which will not be repeated here.

[0036] Re-reference Figure 1-4 Preferably, the two positioning members 33 have groove structures on opposite sides, and the two groove structures cooperate to form a positioning bearing position, which is adapted to the circuit board 100. In specific applications, the positioning member 33 is a positioning block. The circuit board 100 in this embodiment is a rectangular plate, and the groove is a right-angle shape, that is, it is adapted to the diagonal shape of the circuit board 100. When the circuit board 100 is placed on the fixture 31, the groove structure is in close contact with the diagonal of the circuit board 100, so that it is stably carried on the fixture 31, ensuring that it does not shake in the horizontal direction during the welding process, thereby improving the stability of the circuit board 100. Furthermore, the positioning member 33 is detachably connected to the fixture 31. When replacing a circuit board 100 of a different shape for welding, the positioning member 33 can be removed from the fixture member 31 and replaced with a positioning member 33 that matches the shape of the circuit board 100. For example, when the circuit board 100 is a circular circuit board, the positioning member 33 with an arc groove structure can be replaced to match the circular circuit board. In this way, the present embodiment can position circuit boards 100 of different shapes and expand the scope of application. Specifically, the positioning member 33 is detachably connected to the fixture member 31 by screw connection.

[0037] In summary, when the circuit board is placed on the fixture, one side of the circuit board can be welded through the second welding port. By setting the flip assembly, after welding one side of the circuit board, the fixture and the circuit board can be flipped, and the components on the other side of the circuit board can be welded through the first welding port, so that both sides of the circuit board can be welded, improving welding efficiency. At the same time, since there is space between the fixture and the surface of the carrier, the components welded on one side of the circuit board are all located in the space, avoiding direct contact with the carrier, thereby avoiding damage to the components and improving the welding quality of the product.

[0038] The above is only the implementation mode of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
