Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board flipping and positioning device. Background Technology

[0002] A circuit board, also known as a printed circuit board, is a conductive carrier used to connect and support electronic components. It consists of an insulating substrate (usually an epoxy fiberglass board with copper foil cladding) and conductive patterns on it. The main function of a circuit board is to provide circuit connections so that signals can be transmitted between electronic components.

[0003] During circuit board production, the circuit board needs to be fixed before components such as resistors, capacitors, and connectors are sequentially soldered onto it. For example, Chinese Patent Publication No. CN219204858U discloses a circuit board processing positioning structure, including a base plate. A vertical rod is fixedly connected to one end of the upper surface of the base plate, and a connecting seat is fixedly connected to the upper end of the vertical rod. A rotating block is rotatably connected to one side wall of the connecting seat near the center of the base plate, and a plug-in assembly for fixing the rotation angle of the rotating block is provided on the other side wall of the connecting seat. By placing the circuit board between two right-angled locking blocks (one and two), and then rotating a bidirectional screw to engage and fix two right-angled locking blocks at two corners of the circuit board, the circuit board is then fixed by moving a T-shaped slider to engage and fix the other two corners of the circuit board. Finally, rotating the rotating block causes the fixed circuit board to rotate as a whole, so that the back of the circuit board faces upwards. A pin is then used to fix the rotating plate, completing the flipping and fixing of the circuit board. This makes the flipping process quick and convenient, improving work efficiency.

[0004] In actual operation, the rotating bolt clamps the slide bar, and the distance between the right-angled blocks on both sides is adjusted by adjusting the length of the slide bar. However, adjusting by rotating the bolt is slow and affects the clamping efficiency of the circuit board, making it less practical. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the adjustment efficiency of the distance between adjacent right-angle blocks using rotating bolts is relatively slow, and to propose a circuit board flipping and positioning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a circuit board flipping and positioning device, including a base, a flipping mechanism is provided on the top of the base via a bracket, a drive mechanism and a pair of support frames are provided on the output end of the flipping mechanism, and the pair of support frames move relative to each other via the drive mechanism;

[0008] The support frame consists of a first connecting part and a second connecting part. The first connecting part and the second connecting part are fixed together by a locking assembly, and positioning members are provided on opposite sides of the top of each other. The positioning members are used to clamp the circuit board.

[0009] Furthermore, the locking assembly includes a rack, one end of the first connecting part is connected to the driving mechanism, and the other end is slidably connected to the second connecting part through a groove, with the rack embedded in one side of the inner wall of the groove.

[0010] Furthermore, it also includes a movable component, which is slidably connected inside one end of the second connecting part. A connecting rod is fixedly connected to the side of the movable component. The connecting rod passes through the second connecting part via a compression spring and engages with the rack via a wedge-shaped surface.

[0011] Furthermore, an unlocking component is slidably connected inside the second connecting part, and a guide rod is fixedly connected to the unlocking component near the side of the movable component. The end face of the movable component is provided with an inclined groove, and the guide rod is slidably connected to the inclined groove.

[0012] Furthermore, the positioning component has a right-angle structure and each of it has a placement groove inside. The positioning components are respectively engaged with the corners of the circuit board through the placement grooves. A fixing rod is also fixedly connected to the bottom of the positioning component.

[0013] Furthermore, the top and bottom of the first connecting part and the second connecting part are provided with stepped holes and limiting grooves, the free end of the fixing rod is slidably connected in the stepped hole by a spring, and a pair of slots are also provided at the free end of the fixing rod.

[0014] The limiting groove contains a limiting component that is movably inserted into it. The limiting component is inserted into the slot through a clearance groove at one end. The limiting component is used to fix and circumferentially lock the positioning component.

[0015] The circuit board flipping and positioning device proposed in this utility model has the following advantages: This utility model can drive a pair of support frames to move relative to each other through a drive mechanism, and can adjust the length between the first connecting part and the second connecting part through a locking component. Then, in conjunction with the drive mechanism, it can use the positioning component to adapt to circuit boards of different specifications within a certain range, which is convenient for clamping. Moreover, the method of adjusting the length between the pair of connecting parts is simple and quick, which can effectively improve the loading and unloading efficiency of circuit boards. In addition, the positioning component can be disassembled by unlocking the limiting component, which prevents the downtime caused by the inconvenience of replacement. The structure is simple and practical. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A circuit board flipping and positioning device includes a base 1, a flipping mechanism 3 is provided on the top of the base 1 via a bracket 2, a drive mechanism 4 and a pair of support frames 5 are provided on the output end of the flipping mechanism 3, and the pair of support frames 5 can move relative to each other through the drive mechanism 4.

[0024] The support frame 5 is composed of a first connecting part 51 and a second connecting part 52. The first connecting part 51 and the second connecting part 52 are fixed together by a locking component 6, and positioning members 7 are provided on opposite sides of the top of each other. The positioning members 7 are used to clamp the circuit board.

[0025] It should be added that the flipping mechanism 3 includes a motor mounted on the bracket 2, which drives the support plate to rotate through a transmission component, and the drive mechanism 4 is mounted on the support plate.

[0026] Furthermore, the drive mechanism 4 includes a dual-axis lead screw and a guide rod. The guide rod is arranged parallel to the dual-axis lead screw. A pair of support frames 5 are slidably connected to both ends of the guide rod and threadedly connected to the dual-axis lead screw, respectively. The dual-axis lead screw can be driven to rotate manually or by a motor.

[0027] Furthermore, the locking assembly 6 includes a rack 61, one end of the first connecting part 51 is connected to the driving mechanism 4, and the other end is slidably connected to the second connecting part 52 through a slide groove 511. The rack 61 is embedded in one side of the inner wall of the slide groove 511.

[0028] Furthermore, it also includes a movable component 62, which is slidably connected to the inside of one end of the second connecting part 52. A connecting rod 63 is fixedly connected to the side of the movable component 62. The connecting rod 63 passes through the second connecting part 52 through a compression spring 64 and engages with the rack 61 through a wedge-shaped surface.

[0029] The two ends of the compression spring 64 abut against the inner side of the second connecting part 52 and the side of the movable part 62, respectively.

[0030] More specifically, an unlocking component 65 is slidably connected inside the second connecting part 52. A guide rod 66 is fixedly connected to the unlocking component 65 near the movable component 62. The end face of the movable component 62 is provided with a groove 621, and the guide rod 66 is slidably connected to the groove 621.

[0031] In specific operation, one end of the unlocking part 65 extends to the periphery of the second connecting part 52, and the other end is slidably connected above the movable part 62 to avoid blocking the movable part 62.

[0032] Pressing the unlocking part 65 causes the guide rod 66 to move. When the guide rod 66 moves, it drives the movable part 62 to move away from the rack 61 through the inclined groove 621. Then the connecting rod 63 disengages from the rack 61, so that the position of the second connecting part 52 can be adjusted.

[0033] Similarly, under the action of the compression spring 64, the connecting rod 63 is reset and the position of the second connecting part 52 is fixed by engaging the wedge-shaped surface with the tooth groove of the rack 61.

[0034] The specific structure of the inclined groove 621 is as follows: Figure 2 As shown.

[0035] In general, the positioning component 7 has a right-angle structure and each of them has a placement groove inside. The positioning components 7 are respectively engaged with the corners of the circuit board through the placement grooves. A fixing rod 71 is also fixedly connected to the bottom of the positioning component 7.

[0036] Furthermore, the positioning component 7 is provided with a through groove at the corner, which is connected to the placement groove. The through groove avoids the corner of the circuit board and prevents damage to the corner of the circuit board during clamping.

[0037] Finally, the top and bottom of the first connecting part 51 and the second connecting part 52 are provided with stepped holes 53 and limiting grooves 54. The free end of the fixing rod 71 is slidably connected in the stepped hole 53 by a spring 72. A pair of slots 711 are also provided at the free end of the fixing rod 71.

[0038] The limiting member 55 is movably inserted into the limiting groove 54. The limiting member 55 is inserted into the slot 711 through the relief groove 551 at one end. The limiting member 55 is used to fix and circumferentially lock the positioning member 7.

[0039] In this embodiment, the stepped hole 53 has an inverted convex structure, so one end of the spring 72 is fixedly connected to the protruding part of the stepped hole 53, while the other end abuts against the bottom of the positioning member 7; wherein, by compressing the spring 72, the fixing rod 71 can use the slot 711 to clamp the limiting member 55, preventing the limiting member 55 from disengaging from the fixing rod 71, thereby fixing the positioning member 7;

[0040] Furthermore, the limiting member 55 matches the limiting groove 54, and the limiting member 55 stops the positioning member 7 by using the slot 711 to prevent the positioning member 7 from rotating.

[0041] Working method: During operation, the position of the four-sided positioning parts 7 is adjusted according to the actual size of the circuit board. Press the unlocking part 65 to drive the guide rod 66 to move. When the guide rod 66 moves, it drives the movable part 62 to move away from the rack 61 through the inclined groove 621. Then the connecting rod 63 disengages from the rack 61, so that the position of the second connecting part 52 can be adjusted.

[0042] Similarly, under the action of the compression spring 64, the connecting rod 63 is reset and the position of the second connecting part 52 is fixed by engaging the wedge-shaped surface with the tooth groove of the rack 61.

[0043] Then, the dual-axis lead screw is driven to rotate manually or by motor. The dual-axis lead screw, together with the guide rod, drives the support frames 5 on both sides to move relative to each other. The positioning part 7 can then clamp the circuit board using the placement slot.

[0044] Finally, the limiting member 55 can be pulled out directly. After the limiting member 55 is separated from the slot 711, the positioning member 7 can be disassembled and replaced.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
