Description

Technical Field

[0001] The utility model relates to the technical field of electronic component welding, in particular to a welding device for non-planar electronic components. Background Art

[0002] During the welding process of the circuit board, the circuit board always remains in a flat state. However, with the continuous development of science and technology, curved circuit boards have gradually appeared on the market. Curved circuit boards can better adapt to some electrical equipment and are convenient for internal installation. Traditional curved circuit board production is generally divided into two types. One is to weld the electronic components first and then bend the circuit board. The other is to bend the circuit board first and then weld the electronic components. In the case of welding the electronic components first and then bending the circuit board, it is very easy for the pins of the electronic components to fall off and break due to uneven force, causing the circuit board to be scrapped. Therefore, the existing curved circuit boards are generally reproduced by using shaping plates and fixing strips. The flexible straight circuit board is first bent into a curved circuit board, and finally the electronic components are welded. This can effectively solve the problem of the pins of the electronic components falling off and breaking.

[0003] At present, when a non-planar electronic component welding device is used to make a curved circuit board, it is generally necessary to prepare a shaping plate suitable for the bending state of the circuit board in advance according to the curvature of the circuit board to be achieved, and then clamp and shape it with accessories such as fixing strips and screws. Although the above method can achieve the effect of making any curvature, it is necessary to prepare a large number of shaping plates and shaping strips with different curvatures in advance, and it is impossible to quickly adjust the shaping plate to suit the curvature of the circuit board according to demand, resulting in low production efficiency, and a large number of accessories will also cause the production cost to rise. Summary of the invention

[0004] The purpose of the utility model is to propose a welding device for non-planar electronic components to address the problem in the background technology that the shaping plate cannot be quickly adjusted according to demand to suit the curvature of the circuit board bending shaping, resulting in low production efficiency, and a large number of accessories will also cause the production cost to rise.

[0005] The technical solution of the utility model: a welding device for non-planar electronic components includes a base and also includes:

[0006] A groove, wherein the groove is opened on the top of the base;

[0007] An adjustment mechanism for bending the circuit board, wherein the adjustment mechanism is movably mounted in the groove;

[0008] A curved support plate for supporting a curved circuit board, wherein both ends of the curved support plate are fixedly mounted on the adjustment mechanism, and the initial state of the curved support plate is set to be in an upwardly bent state;

[0009] The fixing mechanism is used for fixing the circuit board, and the fixing mechanism is movably mounted on the adjusting mechanism.

[0010] The adjusting mechanism also includes a rotating rod, which is connected through the groove and has one end rotatably connected to the inner wall of the groove. A bidirectional threaded groove is provided on the rotating rod, and the bidirectional threaded grooves on the rotating rod are both threadedly connected to moving blocks. Both ends of the two moving blocks are rotatably connected to connecting strips, and the ends of the multiple connecting strips away from the moving blocks are respectively rotatably connected to two fixed strips, and the opposite sides of the two fixed strips are fixedly connected to L-shaped clamping blocks, and one end of the rotating rod passing through the inner wall of the groove is fixedly connected to the first knob.

[0011] The fixing mechanism also includes two pressure strips, and the two pressure strips are respectively located directly above the two L-shaped clamping blocks. A threaded shaft passes through the middle of the two pressure strips, and the threaded shaft is rotatably connected to the pressure strips. The threaded shaft passes through the top of the pressure strip and is fixedly connected to a second knob. The bottom end of the threaded shaft passes through the top of the L-shaped clamping block and is threadedly connected to the L-shaped clamping block. The bottoms of both ends of the pressure strip are fixedly connected to a limiting shaft, and the limiting shaft passes through the L-shaped clamping block and is limitedly and slidably connected to the L-shaped clamping block.

[0012] The middle part of the rotating rod is rotatably connected to a limiting block, and the limiting block is fixedly connected to the bottom of the inner wall of the groove.

[0013] The inclined surfaces and the opposite side of the two pressure strips are fixedly connected with anti-skid rubber pads.

[0014] The inner wall of the groove is provided with four slide grooves, both ends of the two L-shaped clamping blocks are fixedly connected with sliders, and the four sliders are respectively slidably connected in the four slide grooves.

[0016] The utility model fixes the circuit board by means of a fixing mechanism, and finally, under the adjustment of the adjusting mechanism, the effect of squeezing the two ends of the circuit board is achieved. Since the initial state of the curved support plate is an upwardly bent state, the bending direction of the circuit board during squeezing is always an upward state, thereby satisfying that the circuit board can produce curved circuit boards with any curvature within a certain range under a set of devices, which not only saves production costs, but also avoids the problem of reduced production efficiency caused by constantly replacing the shaping plate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1-4 As shown, the device for welding non-planar electronic components proposed by the utility model comprises a base 1.

[0026] In this embodiment, the welding device for non-planar electronic components also includes a groove 7, which is opened on the top of the base 1; an adjusting mechanism 2 for bending the circuit board, which is movably installed in the groove 7; a curved support plate 6 for supporting the bent circuit board, both ends of the curved support plate 6 are fixedly installed on the adjusting mechanism 2, and the initial state of the curved support plate 6 is set to an upward bent state; a fixing mechanism 3 for fixing the circuit board, which is movably installed on the adjusting mechanism 2.

[0027] First, by placing the circuit board on the curved support plate 6, and then fixing it through the fixing mechanism 3, and finally adjusting the adjustment mechanism 2, the two ends of the circuit board are squeezed. Since the curved support plate 6 is initially in a bent state, the bending direction of the circuit board during extrusion is always upward, thereby satisfying the requirement that a set of devices can be used to produce curved circuit boards with any curvature within a certain range, which not only saves production costs, but also avoids the problem of reduced production efficiency caused by constantly replacing the shaping plate.

[0028] Further, the adjusting mechanism 2 also includes a rotating rod 21, which is connected to the groove 7 through the rotating rod 21 and is rotatably connected to the inner wall of the groove 7 at one end. The rotating rod 21 is provided with a bidirectional threaded groove, and the bidirectional threaded grooves on the rotating rod 21 are threadedly connected to the moving blocks 22. Both ends of the two moving blocks 22 are rotatably connected to connecting strips 23, and one end of the multiple connecting strips 23 away from the moving blocks 22 is rotatably connected to two fixing strips 24, and the opposite sides of the two fixing strips 24 are fixedly connected to L-shaped clamping blocks 25. One end of the rotating rod 21 that passes through the inner wall of the groove 7 is fixedly connected to a first knob. By rotating the first knob, the rotating rod 21 is driven to rotate, and the bidirectional threaded grooves on the rotating rod 21 are respectively threadedly connected to the two moving blocks 22, so that the two moving blocks 22 can be driven to move relative to or away from each other. At this time, with the cooperation of the multiple connecting strips 23, the two fixing strips 24 and the two L-shaped clamping blocks 25 can be driven to move relative to or away from each other, thereby achieving the extrusion and bending effect on the two ends of the circuit board.

[0029] The two ends of the clamping strip 31 are fixedly connected to the bottom of the clamping strip 31, and the two ends of the clamping strip 31 are fixedly connected to the bottom of the clamping strip 31. The two ends of the clamping strip 31 are fixedly connected to the limiting shaft 33, and the limiting shaft 33 passes through the L-shaped clamping block 25 and is limitedly slidably connected to the L-shaped clamping block 25. By rotating the second knob, the threaded shaft 32 rotates downward at the top of the L-shaped clamping block 25 and drives the clamping strip 31 downward, thereby achieving the effect of limiting and clamping the top of the two ends of the circuit board. At the same time, the sliding connection between the two limiting shafts 33 and the top of the L-shaped clamping block 25 can improve the stability of the clamping strip 31 when moving downward and the clamping effect on the circuit board.

[0030] In addition, the middle part of the rotating rod 21 is rotatably connected to a limiting block, and the limiting block is fixedly connected to the bottom of the inner wall of the groove 7. Through the above arrangement, the stability of the rotating rod 21 during rotation can be enhanced, and the rotating rod 21 can be prevented from deviating and shaking.

[0031] Among them, the inclined surfaces of the two pressure strips 31 and the opposite side of the L-shaped clamping block 25 are fixedly connected with anti-slip rubber pads. Through the above settings, the two ends of the circuit board can be protected to avoid damage when the two ends of the circuit board are squeezed and stressed. At the same time, the anti-slip effect of the two ends of the circuit board can be improved, and the stability of the circuit board when bending can be improved.

[0032] At the same time, four slide grooves 4 are opened on the inner wall of the groove 7, and sliders 5 are fixedly connected to both ends of the two L-shaped clamping blocks 25, and the four sliders 5 are respectively slidably connected in the four slide grooves 4. Through the above settings, the L-shaped clamping block 25 can be limited when it slides, preventing the L-shaped clamping block 25 from escaping from the groove 7, thereby improving the stability of the L-shaped clamping block 25 when sliding, and enhancing the stability of the circuit board when bending.

[0033] Working principle: By turning the first knob, the rotating rod 21 is driven to rotate, and the two moving blocks 22 are respectively threadedly connected with the two moving blocks 22 through the bidirectional thread grooves on the rotating rod 21, so that the two moving blocks 22 can be driven to move relative to or away from each other. At this time, with the cooperation of multiple connecting bars 23, the two fixing bars 24 and the two L-shaped clamping blocks 25 can be driven to move relative to or away from each other, thereby achieving the extrusion and bending effect on both ends of the circuit board;

[0034] In addition, by turning the second knob, the threaded shaft 32 rotates downward at the top of the L-shaped clamping block 25, and drives the pressure strip 31 downward, thereby achieving the effect of limiting and clamping the tops of both ends of the circuit board. At the same time, the sliding connection between the two limiting shafts 33 and the top of the L-shaped clamping block 25 can improve the stability of the pressure strip 31 when it moves downward and the clamping effect on the circuit board.

[0035] Under the adjustment of the adjustment mechanism 2, the two ends of the extruded circuit board are reached. Since the curved support plate 6 is initially in a bent state, the bending direction of the circuit board during extrusion is always upward, thereby satisfying the requirement that a set of devices can be used to produce curved circuit boards with any curvature within a certain range, which not only saves production costs, but also avoids the problem of reduced production efficiency caused by constantly replacing the shaping plate.

[0036] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
