Description

Technical Field

[0001] This application relates to the field of circuit board processing technology, and in particular to a circuit board development and design fixture. Background Technology

[0002] In the field of electronic design, circuit boards (PCBs), as the carriers of electronic components, are highly dependent on fixtures in their development, debugging, and repair processes. The core function of a fixture is to fix the circuit board, ensuring the accuracy and stability of operations such as soldering and testing, while also adapting to diverse operating angles and orientations. With the increasing miniaturization and integration of electronic devices, the structural complexity of circuit boards is constantly increasing, placing higher demands on the adjustability, compatibility, and ease of operation of fixtures. Efficient fixtures not only reduce manual positioning errors but also reduce operator fatigue by quickly adjusting the working angle, significantly improving development efficiency.

[0003] In the existing technology, the mainstream circuit board fixtures are mainly divided into two categories: fixed fixtures and simple adjustable fixtures. Fixed fixtures use a rigid frame structure and fix the circuit board by bolts, buckles, etc. This method can only achieve horizontal fixation of the circuit board and cannot meet the needs of tilting operation. Simple adjustable fixtures use a hinge structure or gear rack mechanism to achieve angle adjustment, but the adjustment range is limited and cannot adjust the tilt angle and horizontal rotation angle of the circuit board according to the needs, making it difficult to meet the needs of multi-directional operation, thus affecting the development efficiency of electronic design.

[0004] Therefore, it is necessary to provide a new technical solution to improve one or more of the problems existing in the above solutions. Utility Model Content

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0041] Furthermore, the accompanying drawings are merely illustrative of this application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.

[0042] This example implementation first provides a circuit board development and design fixture. (Reference) Figures 1 to 5 As shown, the circuit board development and design fixture includes: an angle adjustment part 100, a fixing part 200, and a rotating part 300; wherein, the angle adjustment part 100 has a first support plate 110 and a second support plate 120 that are hinged to each other, and the second support plate 120 can rotate about the hinge point as the center; the fixing part 200 is fixedly connected to the top surface of the second support plate 120 of the angle adjustment part 100, and is used to fix the circuit board to the top surface of the second support plate 120 of the angle adjustment part 100; the rotating part 300 has its top surface fixedly connected to the bottom surface of the first support plate 110 of the angle adjustment part 100, and is used to rotate and adjust the horizontal angle of the angle adjustment part 100.

[0043] Using the aforementioned circuit board development and design fixture, the circuit board is fixed to the second support plate 120 of the angle adjustment unit 100 via the fixing part 200. By adjusting the tilt angle of the second support plate 120 of the angle adjustment unit 100, the tilt angle of the circuit board development and processing can be adjusted vertically from 0 to 45°. At the same time, by rotating the rotating part, the circuit board fixed on the second support plate 120 can be adjusted to rotate horizontally 360°, thereby realizing multi-directional adjustment of the tilt angle and position of the circuit board.

[0044] In one embodiment, the angle adjustment unit 100 further includes an angle adjustment mechanism 130 for adjusting the vertical angle of the second support plate 120.

[0045] It is understandable that the angle adjustment mechanism 130 can be hinged at one end to the bottom surface of the second support plate 120 and movably connected to the first support plate 110 at the other end, so that when the end movably connected to the first support plate 110 is pushed close to the hinge point between the first support plate 110 and the second support plate 120, the second support plate 120 is lifted up until the angle adjustment mechanism 130 is perpendicular to the first support plate 110; or it can be a telescopic rod, which lifts the second support plate 120 by extending or retracting the telescopic rod.

[0046] Further, optionally, the angle adjustment mechanism 130 includes a first lead screw 131, a moving block 132, and an adjustment frame 133;

[0047] The first lead screw 131 is rotatably connected between two first connecting pieces 111 on the top surface of the first support plate 110;

[0048] The moving block 132 is engaged with the first lead screw 131;

[0049] One end of the adjustment frame 133 is horizontal and perpendicular to the first lead screw 131 and can be rotatably inserted in the moving block 132, while the other end can be rotatably connected to the bottom surface of the second support plate 120.

[0050] It should be noted that the rotation of the first lead screw 131 drives the moving block 132 to move on the first lead screw 131, thereby driving the adjusting frame 133 to lift and pull down the second support plate 120. At the same time, it can be understood that the rotational connection between the adjusting frame 133, the bottom surface of the second support plate 120, and the moving block 132 needs to be subjected to a certain force to rotate, so as to avoid the second support plate 120 tilting angle being unstable.

[0051] Optional, such as Figure 4 As shown, the bottom surface of the movable block 132 has a second protrusion 1321, the top surface of the first support plate 110 has a first groove 112, and the second protrusion 1321 is slidably disposed in the first groove 112.

[0052] It is understandable that by cooperating with the first groove 112, the second protrusion 132 is further limited, thereby reducing the force on the first lead screw 131 when the moving block 132 moves.

[0053] Optionally, one end of the first lead screw 131 is equipped with a motor, which drives the lead screw to rotate through the rotation of the motor output shaft.

[0054] In one embodiment, the fixing part 200 includes a clamping member 210 and a limiting plate 220;

[0055] The limiting plate 220 is disposed at one end of the top surface of the second support plate 120 and is used to limit one end of the circuit board.

[0056] The clamping member 210 is disposed at the other end of the top surface of the second support plate 120 and is used to squeeze and limit the other end of the circuit board.

[0057] It is understandable that the circuit board is fixed by applying pressure to both ends of the circuit board through the clamping member 210 and the limiting plate 220.

[0058] Furthermore, such as Figure 1 , 3 As shown, optionally, the clamping member 210 includes a second connecting member 211, a second lead screw 212, and a limiting block 213;

[0059] The second connector 211 is fixedly connected to the top surface of the second support plate 120, and has a screw hole in the middle;

[0060] The second lead screw 212 is engaged and inserted into the screw hole, and the end near the limiting plate 220 has the limiting block 213.

[0061] It should be noted that by rotating the second lead screw 212, the limiting block 213 gradually approaches / moves away from the limiting plate 220, thereby achieving the compression and fixation of the circuit board. When adjusting the angle between the first support plate 110 and the second support plate 120 by the second lead screw 212 and the limiting block 213, the first support plate 110 and the second support plate 120 can be hinged by the rotating shaft 230, which facilitates the adjustment of the angle between the first support plate 110 and the second support plate 120.

[0062] Optionally, the limiting plate 220 has a slot on the side near the clamping member 210 for engaging one end of the circuit board.

[0063] It is understandable that, such as Figure 1 As shown, the slot spacing is adapted to the circuit board, and the circuit board is prevented from sliding when it is squeezed and limited.

[0064] Optionally, the end of the second lead screw 212 away from the limiting block 213 has a handle 214 to facilitate the rotation of the second lead screw 212.

[0065] In one embodiment, such as Figure 5 As shown, the rotating part 300 includes a central column 320, a turntable 330, and a plurality of springs 340;

[0066] The turntable 330 includes a fixed layer 331 and a rotating layer 332, the rotating layer 332 and the fixed layer 331 are rotatably connected, and the bottom surface of the fixed layer 331 is fixedly connected to the central column 320.

[0067] The central column 320 is used to support the turntable 330;

[0068] One end of the spring 340 is fixedly connected to the bottom surface of the rotating layer 332.

[0069] It is understandable that the spring force of the spring 340 on both ends can fix the rotating layer 332 in the appropriate position. When rotation is required, each spring 340 can be pulled up for adjustment.

[0070] Optionally, a base 310 is fixed to the bottom surface of the central column 320, thereby improving the stability of the rotating part 300 supporting the angle adjustment part 100.

[0071] Furthermore, optionally, the rotating part 300 also includes a movable ring 350, and the other end of the spring 340 is fixedly connected to the top surface of the movable ring 350.

[0072] Understandably, the movable ring 350 enables the convenient one-time lifting of multiple springs 340, facilitating the rotation of the rotating layer 332.

[0073] Optionally, the springs 340 array is distributed between the bottom surface of the rotating layer 332 and the top surface of the moving ring 350, the moving ring 350 having an extending bent rod.

[0074] It is understandable that, such as Figure 5 As shown, by setting an extended bent rod, the pulling and compression of multiple springs 340 are further improved.
