Technical Field

[0001] The utility model relates to the technical field of PCB board production, and particularly relates to a bending needle shaping device for a PCB board. Background Technique

[0002] In the process of circuit board manufacturing, a bending needle is a common connecting component used to achieve electrical connection between a circuit board and other components.

[0003] After retrieval, a utility model with the Chinese patent publication number CN215268949U discloses an auxiliary device for shaping bending needles of a double-row hole PCB board, which relates to the technical field of PCB board processing. The device includes a device body. One side of the device body is provided with a groove. At least one fixing cylinder is provided on one side of the bottom of the groove. A PCB board is sleeved on the fixing cylinder. Fixing clips are provided on both sides of the top of the device body, and the fixing clips are connected to the PCB board. Mounting posts are provided at both ends of the groove.

[0004] The above device fixes the shape of the bending needle through an auxiliary thin plate. Then, when in use, the bending needle needs to be inserted into multiple wire hole grooves in sequence. Since the aperture of the wire hole groove is small, the plugging process will be time-consuming, which will affect the production efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bending needle shaping device for a PCB board to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A bending needle shaping device for a PCB board includes a positioning frame. A shaping component is installed inside the positioning frame. The shaping component includes a toothed plate slidably inserted into the inner wall of the positioning frame. Multiple equidistantly distributed three-dimensional triangles are provided at one end of the toothed plate. A horizontally arranged limiting rod is fixedly connected to the outer walls on both sides of the positioning frame. The same push plate is slidably sleeved outside the two limiting rods, and the push plate is arranged opposite to the toothed plate. A spring is sleeved outside each of the two limiting rods, and the two springs are respectively fixedly connected to the end of the limiting rod and the push plate.

[0007] When the pin can be inserted into the gap of the toothed plate, there is no need for an accurate docking process, and the operation is simple enough. After the insertion is completed, the arrangement pattern of multiple pins can be quickly determined. The through holes formed between the toothed plate and the positioning frame are triangular. When it is not stressed, the area is large, so the pins can be easily placed into multiple triangular holes. Then, press the outer wall of the push plate and the inner wall of the positioning frame simultaneously, and the push plate will slide along the limiting rod. Furthermore, the toothed plate will be driven by the push plate to move synchronously. The triangular holes formed between it and the positioning frame will gradually become smaller, and the pins will be gradually corrected into a vertical state. Because the pins can be pressed to fit the inner wall of the positioning frame, the two will remain parallel. With the restriction of the tip of the triangular hole, multiple pins will be in a vertical state, and the spacing of multiple pins will also be consistent.

[0008] As a further preference of this technical solution, two blocks are fixedly connected to the outer wall of one end of the toothed plate. The same connecting rod is fixedly connected to the inner walls on both sides of the push plate. Both of the two blocks are sleeved outside the connecting rod. A baffle is rotatably connected to the bottom of the outer wall of one end of each of the two blocks through a bearing. The two baffles can just fit the outer wall of the connecting rod. A magnetic strip is rotatably connected to the outer wall of one side of each of the two baffles. The two magnetic strips can be respectively adsorbed on the outer walls of the two blocks.

[0009] As a further preference of this technical solution, a fixing component is installed on the top of the positioning frame, and the fixing component is arranged opposite to the push plate.

[0010] As a further preference of this technical solution, the fixing component includes a limiting groove opened at one end of the outer wall of the top of the positioning frame. A horizontally arranged bidirectional lead screw is rotatably connected inside the limiting groove. Threaded sleeves are respectively sleeved on the threads at both ends of the bidirectional lead screw. Both of the two mounting seats are in contact with the inner wall of the limiting groove. A knob is arranged in the middle of the bidirectional lead screw.

[0011] As a further preference of this technical solution, a support rod is rotatably connected to the top outer wall of each of the two mounting seats through a bearing. One end of each of the two support rods is rotatably connected to the same magnet through a support. The magnet can be adsorbed on the inner wall of one side of the push plate.

[0012] After the shaping operation is completed, the push plate will fit the magnet. Under the action of the magnetic force, the position of the push plate will be fixed, and there is no need to continuously press. Since the models of the pins are different, the moving distance of the toothed plate is also limited. At this time, the position of the magnet can also be adjusted to ensure the fixing effect. Drive the bidirectional lead screw to rotate through the knob, and the two mounting seats restricted by the limiting groove will approach each other. The two of them cooperate with the two support rods to drive the magnet to move away from the positioning frame, so as to ensure that the magnet can just fit the push plate tightly, which is beneficial to improving the fixing effect.

[0013] As a further preference of the technical solution, a slide bar is slidably inserted at both ends of the inner wall on one side of the positioning frame, and the same bending bar is fixedly connected to one end of the two slide bars, and the bending bar can pass through the groove on the top of the positioning frame.

[0014] As a further preference of the technical solution, arc-shaped edges are provided on the edges of the groove on the top of the positioning frame.

[0015] The utility model has the following beneficial effects: (1) By setting the shaping component, when the pin is inserted into the gap of the toothed plate, there is no need for an accurate docking process, and the operation is simple enough. After the insertion is completed, the arrangement pattern of multiple pins can be quickly determined. The through holes formed between the toothed plate and the positioning frame are triangular. When it is not stressed, the area is large, so the pins can be easily placed into multiple triangular holes. Then, by pressing the outer wall of the push plate and the inner wall of the positioning frame at the same time, the push plate will slide along the limiting rod, and then the toothed plate will also be driven by the push plate to move synchronously. The triangular holes formed between it and the positioning frame will gradually become smaller, and the pins will be gradually corrected into a vertical state. Because the pins can be pressed against the inner wall of the positioning frame and the two will remain parallel, with the restriction of the tip of the triangular hole, multiple pins will be in a vertical state, and the spacing between multiple pins will also be consistent.

[0016] (2) By setting the fixing component, after the shaping operation is completed, the push plate will fit with the magnet, and under the action of magnetic force, the position of the push plate will be fixed, and there is no need to continuously press. Since the models of the pins are different, the moving distance of the toothed plate is limited. At this time, the position of the magnet can also be adjusted to ensure the fixing effect. By rotating the knob to drive the bidirectional screw rod to rotate, the two mounting seats restricted by the limiting grooves will approach each other, and the two of them cooperate with the two support rods to drive the magnet to move away from the positioning frame, so as to ensure that the magnet can just fit tightly with the push plate, which is beneficial to improving the fixing effect.

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] This embodiment discloses a PCB board bent needle shaping device, as Figure 1 and Figure 3 shown, including a positioning frame 1. A shaping component 5 is installed inside the positioning frame 1. The shaping component 5 includes a toothed plate 501 slidably inserted into the inner wall of the positioning frame 1. One end of the toothed plate 501 is provided with a plurality of equidistantly distributed three-dimensional triangles. A horizontally arranged limiting rod 503 is fixedly connected to the outer walls on both sides of the positioning frame 1. The same push plate 502 is slidably sleeved outside the two limiting rods 503, and the push plate 502 is arranged opposite to the toothed plate 501. A spring 504 is sleeved outside each of the two limiting rods 503. The two springs 504 are fixedly connected to the ends of the limiting rods 503 and the push plate 502 respectively. The through hole formed between the toothed plate 501 and the positioning frame 1 is triangular. When it is not stressed, the area is larger. Therefore, the pin can be easily placed into a plurality of triangular holes. Then, press the outer wall of the push plate 502 and the inner wall of the positioning frame 1 at the same time. The push plate 502 will slide along the limiting rod 503. Furthermore, the toothed plate 501 will also be driven by the push plate 502 to move synchronously. The triangular hole formed between it and the positioning frame 1 will gradually become smaller, and the pin will be gradually corrected into a vertical state. Because the pin can be pressed to fit the inner wall of the positioning frame 1, the two will remain parallel. With the restriction of the tip of the triangular hole, a plurality of pins will all be in a vertical state, and the spacing between a plurality of pins will also remain consistent.

[0024] The outer wall of one end of the tooth plate 501 is fixedly connected to two blocks 505, and the inner walls on both sides of the push plate 502 are fixedly connected to the same connecting rod 507. The two blocks 505 are both sleeved on the outside of the connecting rod 507. The bottom of the outer wall of one end of the two blocks 505 is rotatably connected to a baffle 506 through a bearing. The two baffles 506 can just fit with the outer wall of the connecting rod 507. The outer wall of one side of the two baffles 506 is rotatably connected to a magnetic strip 508. The two magnetic strips 508 can be adsorbed on the outer walls of the two blocks 505 respectively. A suitable tooth plate 501 is inserted into the through groove in the middle of the positioning frame 1. When the two tooth plates 501 at its ends are clamped on the outside of the connecting rod 507 and stop, the baffle 506 is flipped upward, and then the magnetic strip 508 is flipped from the vertical direction to the horizontal direction. At this time, the magnetic strip 508 will be adsorbed on the outer wall of the block 505, and the tooth plate 501 will be connected to the connecting rod 507. The force direction of the baffle 506 is not parallel to the rotation direction, so the connection state of the two will not change with use.

[0025] like Figure 1 and Figure 4 As shown, a fixing assembly 6 is mounted on the top of the positioning frame 1, and the fixing assembly 6 is arranged opposite to the push plate 502. The fixing assembly 6 includes a limiting groove 601 formed at one end of the outer wall of the top of the positioning frame 1. A horizontally arranged bidirectional screw 602 is rotatably connected to the limiting groove 601. The threaded ends of the bidirectional screw 602 are threadedly sleeved with a mounting seat 603. Both mounting seats 603 are in contact with the inner wall of the limiting groove 601, and a knob is provided in the middle of the bidirectional screw 602.

[0026] The outer walls of the tops of the two mounting seats 603 each have a support rod 604 that rotates via a bearing. One end of the two support rods 604 is connected to the same magnet 605 through support rotation. The magnet 605 can be adsorbed on the inner wall of one side of the push plate 502.

[0027] After the shaping operation is completed, the push plate 502 will fit with the magnet 605. Under the action of the magnetic force, the position of the push plate 502 will be fixed without continuous pressing. Due to the different models of the pin headers, the moving distance of the tooth plate 501 is also limited. At this time, the position of the magnet 605 can also be adjusted to ensure the fixing effect. The two-way screw rod 602 is driven to rotate by the knob, and the two mounting seats 603 restricted by the limit slot 601 will approach each other. The two can cooperate with the two support rods 604 to drive the magnet 605 to move away from the positioning frame 1, which can ensure that the magnet 605 can fit tightly with the push plate 502, which is conducive to improving the fixing effect.

[0028] like Figure 1As shown in the figure and Figure 2, a slide bar 2 is slidably inserted at both ends of the inner wall on one side of the positioning frame 1. One end of the two slide bars 2 is fixedly connected to the same bent strip 3, and the bent strip 3 can pass through the groove at the top of the positioning frame 1. Press the bent strip 3, and under the action of the two slide bars 2, it will slowly move parallel to the arc edge 4 direction, and then the bent strip 3 and the positioning frame 1 can fold the end of the pin header into a bent head. The arc edges 4 are provided on the side lines of the groove at the top of the positioning frame 1, which can prevent the pin header from being damaged by shearing due to overly sharp corners when being bent.

[0029] The utility model provides a PCB board bent pin shaping device, and the specific working principle is as follows:

[0030] When the device works, select a suitable toothed plate 501 according to needs, insert the toothed plate 501 through the through groove in the middle of the positioning frame 1, and stop when the two toothed plates 501 at its end are clamped outside the connecting rod 507. Then turn the baffle 506 upwards, and then flip the magnetic strip 508 to change from the vertical direction to the horizontal direction. At this time, the magnetic strip 508 will adsorb on the outer wall of the block 505, and the toothed plate 501 will be connected to the connecting rod 507. And the force direction of the baffle 506 is not parallel to the rotation direction, so their connection state will not change with use. The through hole formed between the toothed plate 501 and the positioning frame 1 is triangular. When it is not stressed, the area is large, so the pin headers can be easily placed into multiple triangular holes. Then press the outer wall of the push plate 502 and the inner wall of the positioning frame 1 at the same time, and the push plate 502 will slide along the limiting rod 503. Furthermore, the toothed plate 501 will also be driven by the push plate 502 to move synchronously, and the triangular hole formed between it and the positioning frame 1 will gradually become smaller, and the pin headers will be gradually corrected into a vertical state. Because the pin headers can be pressed to fit the inner wall of the positioning frame 1, the two will remain parallel. With the restriction of the tip of the triangular hole, multiple pin headers will all be in a vertical state, and the spacing of multiple pin headers will also be consistent. After the shaping operation is completed, the push plate 502 will fit with the magnet 605, and under the magnetic force, the position of the push plate 502 will be fixed, and there is no need to continuously press. Since the models of the pin headers are different, the moving distance of the toothed plate 501 is also limited. At this time, the position of the magnet 605 can also be adjusted to ensure the fixing effect. Rotate the bidirectional screw rod 602 driven by the knob, and the two mounting seats 603 restricted by the limiting groove 601 will approach each other. The two cooperate with the two support rods 604 to drive the magnet 605 to move away from the positioning frame 1, so as to ensure that the magnet 605 can just fit tightly with the push plate 502, which is beneficial to improving the fixing effect. Finally, press the bent strip 3, and under the action of the two slide bars 2, it will slowly move parallel to the arc edge 4 direction, and then the bent strip 3 and the positioning frame 1 can fold the end of the pin header into a bent head.
