[0002] Currently, circuit board soldering usually requires the use of fixtures for positioning. Specific positions of the fixture are exposed outside the fixture, allowing the soldering equipment to solder only the exposed positions to avoid mis-soldering.

[0003] Most existing fixtures place the circuit board with the side to be soldered facing upwards, which can cause components on the circuit board surface to be squeezed or displaced under the pressure of the top cover, affecting the yield. Summary of the Invention

[0004] This utility model addresses the problems of the prior art by providing a flip-type circuit board soldering fixture. By flipping the fixture, the side of the circuit board to be soldered is mounted face down, thus avoiding the top cover of the fixture pressing on the components.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a flip-type circuit board soldering fixture, including a base, a bracket, a limiting member, and a top cover. The base is provided with multiple mounting slots for accommodating circuit boards. The top cover is rotatably mounted on the base and is used to cover the multiple mounting slots. The base is rotatably mounted on the bracket, and the limiting member is mounted on the bracket.

Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, the present invention provides a flip-type circuit board soldering fixture, including a base 1, a bracket 2, a limiting member 3, and a top cover 4. The base 1 is provided with a plurality of mounting slots 11 for accommodating circuit boards. The top cover 4 is rotatably mounted on the base 1 and is used to cover the plurality of mounting slots 11. The base 1 is rotatably mounted on the bracket 2, and the limiting member 3 is mounted on the bracket 2. The bottom of the base 1 is provided with a plurality of soldering holes 12, which are respectively connected to the plurality of mounting slots 11. The limiting member 3 is used to abut against the top cover 4 after the base 1 is flipped.

[0022] Specifically, the height of the limiting member 3 is not less than the height of the base 1. In use, the base 1 is flipped so that the top cover 4 is facing upwards. Then, the top cover 4 is opened and the circuit board to be soldered is installed into the mounting slot 11 with the soldering end facing downwards. The soldering position of the circuit board will be exposed to the outside through the soldering hole 12. Then, the top cover 4 is closed, and the base 1 and the top cover 4 are flipped so that the top cover 4 abuts against the limiting member 3. At this time, the base 1 is tilted upwards so that the soldering position of the circuit board is tilted upwards, so that the external soldering equipment can be aligned and solder the circuit board.

[0023] This invention uses a flipping mechanism to allow the components on the circuit board to contact the base 1, preventing the components from being squeezed or displaced by the force of the top cover 4 after it is closed, thus ensuring stable welding and high product yield.

[0024] Specifically, the specifications of the welding hole 12 can either expose only the position to be welded, or allow all components of the circuit board to be exposed to the outside world. That is, the top cover 4 and the base 1 cooperate to only press the circuit board, thereby further preventing the components of the circuit board from being squeezed.

[0025] In this embodiment, the bracket 2 is further provided with a support member 5. The top of the support member 5 is provided with a first magnetic member 51, and the top of the top cover 4 is provided with a corresponding second magnetic member 41. The first magnetic member 51 and / or the second magnetic member 41 have magnetic force, and the first magnetic member 51 and the second magnetic member 41 are magnetically attracted to each other. That is, when the top cover 4 of the base 1 is facing upward, the base 1 is supported by the cooperation of the bracket 2 and the support member 5 to ensure that the base 1 will not deflect; while when welding is required, the bracket 2 and the limiting member 3 cooperate to support the base 1.

[0026] It should be noted that in this embodiment, the first magnetic component 51 and the second magnetic component 41 can both be magnets, or one of them can be a magnet and the other can be a magnetizable metal such as iron or copper.

[0027] In this embodiment, the top cover 4 is provided with a third magnetic element 45, and the base 1 is provided with a fourth magnetic element 13. The third magnetic element 45 and / or the fourth magnetic element 13 have magnetic force, and the third magnetic element 45 and the fourth magnetic element 13 are magnetically attracted to each other. That is, the base 1 and the top cover 4 are also connected by magnets, thereby ensuring the stability of the closure and making it easy for staff to open the top cover 4.

[0028] The third magnetic component 45 and the first magnetic component 51 can be the same permanent magnet or two different permanent magnets / metal components. The relationship between the third magnetic component 45 and the fourth magnetic component 13 can be referred to as the relationship between the first magnetic component 51 and the second magnetic component 41, and will not be repeated here.

[0029] In this embodiment, a mold core 10 is detachably disposed inside the base 1, a plurality of mounting slots 11 are disposed in the mold core 10, and a plurality of welding holes 12 are disposed in the base 1.

[0030] Specifically, the base 1 is provided with a disassembly groove 14, and the mold core 10 is installed in the disassembly groove 14. The base 1 can also be detachably provided with at least two limiting strips 15, which are used to limit the mold core 10 into the disassembly groove 14. That is, the operator can adjust the mounting groove 11 by replacing the mold core 10 according to the actual circuit board specifications, so that the present invention can fix circuit boards of the specified size, improving flexibility. The connection between the base 1 and the limiting strips 15 is preferably a screw connection, which is easy for the operator to operate.

[0031] In this embodiment, the top cover 4 is provided with a plurality of clearance holes 42, each corresponding to a plurality of mounting slots 11; the top cover 4 is also provided with a plurality of soft pads 43, each corresponding to a plurality of mounting slots 11. The clearance holes 42 serve to dissipate heat, while the soft pads 43 are used to abut against the circuit board, thereby reducing the impact force received by the circuit board. The soft pads 43 are preferably made of commonly used soft materials such as silicone.

[0032] In this embodiment, the bracket 2 includes a base plate 21 and two rotating pillars 22. The limiting member 3, the supporting member 5, and the two rotating pillars 22 are all set on the floor. The two rotating pillars 22 are arranged facing each other. The base 1 is located between the limiting member 3 and the two rotating pillars 22. The two sides of the base 1 are respectively provided with rotating shafts 16. The two rotating shafts 16 and the two rotating pillars 22 are rotatably installed in a one-to-one correspondence.

[0033] In this embodiment, one end of the top cover 4 is rotatably connected to the base 1, and the other end of the top cover 4 is provided with a handle 44 for easy control by the operator. Preferably, the connection between the top cover 4 and the base 1 is achieved through a hinge.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
