Description

Technical Field

[0001] The present application relates to the technical field of UAV manufacturing, and in particular to a soldering tool for teaching UAV circuit boards. Background Art

[0002] With the progress of the times, drones have become popular nowadays, and some of them have become a platform for students to learn and improve their intelligence. Students can improve their hands-on ability and develop innovative thinking by assembling drones by themselves. At the same time, they can also master certain hardware assembly and software programming thinking logic, which is conducive to the all-round development of young people. In the process of drone teaching, students can use the 3D drawing software they have mastered to design, produce and assemble drones by themselves, use the PADS series software to design drone circuit boards, and assemble and solder them by themselves. Experience the development process of drones completely. Bring theory into reality and improve students' comprehensive quality.

[0003] In order to cultivate students' hands-on ability of soldering, circuit boards without any electronic components and the required components are usually issued. After learning the theoretical knowledge of circuit boards, students need to perform the soldering operation of components on the circuit boards by themselves. This operation is performed on a flat teaching table. Usually, the pins of the components are larger than the thickness of the circuit board after bending, resulting in the need to cut off the excess pins after soldering one. This is repeated, and the convenience of operation is reduced. At the same time, even after cutting off the pins, the height of the soldering position is still greater than the horizontal plane of the circuit board. Therefore, the circuit board is tilted at this time, which is not conducive to subsequent soldering operations. Therefore, in order to solve the above problems, this application uses the 3D printing equipment that is also needed in the teaching process to design a teaching drone circuit board soldering tool.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0023] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0024] Example 1: Reference Figure 1 - Figure 4 A soldering tool for a circuit board 2 of a teaching drone, comprising a circuit board 2 and a support plate 3 below the circuit board 2, a clamping assembly being arranged on the support plate 3, an inner plate 9, an inner ring 8 and an outer ring 1 being threadedly connected in sequence from the inside to the outside being arranged below the support plate 3, the inner plate 9, the inner ring 8 and the outer ring 1 being threadedly connected to adjust the horizontal height of the support plate 3, the support plate 3 and the inner plate 9 being rotatably connected, a bearing 10 being coaxially fixedly connected to the top of the inner plate 9, and the inner ring of the bearing 10 being fixedly connected to the support plate 3, the outer ring and the inner plate 9 is fixedly connected, and the bearing 10 is used to realize the stable rotation of the support plate 3 on the inner plate 9. A fixed shaft matching the bearing 10 is welded at the bottom center of the support plate 3. The outer wall of the inner plate 9 is provided with an external thread 2 92, the inner wall of the inner ring 8 is provided with an internal thread 2 83, the outer wall is provided with an external thread 1 82, and the inner wall of the outer ring 1 is provided with an internal thread 111. The internal thread 111 and the external thread 1 82 are threadedly connected, and the internal thread 2 83 and the external thread 2 92 are threadedly connected;

[0025] The outer ring array of the inner disk 9 is provided with a second socket 91, and the inner ring 8 is provided with a first socket 81 in a ring array. The top view of the first socket 81 and the second socket 91 adopts a non-circular structure, such as a rectangular structure. The first socket 81 and the second socket 91 are set identically. The first socket 81 and the second socket 91 are provided with an operating rod 7 that cooperates with them. The operating rod 7 is an L-shaped structure, and its vertical section is slidably fitted with the first socket 81 or the second socket 91, so that when the horizontal section of the operating rod 7 is manipulated, the inner disk 9 or the inner ring 8 can be rotated, and the threaded connection relationship can be used to lift the height of the support disk 3, so as to adjust the support disk 3 to a suitable operating height, thereby improving the practicality of the device.

[0026] A support leg 4 is welded to the outer bottom of the outer ring 1, and a suction cup 5 is fixedly connected to the bottom of each support leg 4. The suction cup 5 can be used to stabilize the position of the outer ring 1, thereby preventing the outer ring 1 and the inner ring 8 from rotating synchronously during the rotation process.

[0027] The support plate 3 is evenly provided with a plurality of positioning holes 31. The clamping assembly includes a plug-in rod 61 inserted into the positioning hole 31 and a limit block 63 fixed on the plug-in rod 61. The limit block 63 is movably connected with a movable block 62 for clamping the circuit board 2 in the horizontal direction. The vertical section of the limit block 63 is threadedly connected with a knob 64, and the knob 64 passes through the end of the limit block 63 and is rotatably connected with the movable block 62. When the knob 64 is turned, the end of the knob 64 pushes the movable block 62 to slide along its axial direction. The movement stability of the movable block 62 is controlled by the limit block 63. The four clamping blocks 6 cooperate with each other to clamp the edge position of the circuit board 2. The side of the movable block 62 away from the limit block 63 is a continuous step-like structure. The continuous step-like structure can adjust the height area of ​​the circuit board 2. At the same time, the continuous step-like structure can make the height of the circuit board 2 adjustable, so as to realize the placement and fixation on the clamping block 6 when electronic components are welded on the back.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
