Description

Technical Field

[0001] This utility model belongs to the technical field of diode lead production equipment, specifically relating to a diode lead bending head and bending mechanism. Background Technology

[0002] In electronic components, a diode is a device with two electrodes that allows current to flow in only one direction. The electrode leads of a diode are two copper wires, and these leads need to be bent into different shapes depending on the application.

[0003] Currently, large-angle bending of diode leads is mainly achieved in two ways. One is by manual bending, but manual operation is inefficient and it is not easy to unify the product standards after forming. The other is by forming with a mold and extrusion, such as the patent with publication number CN104368730A entitled "A Diode Bending and Shaping Tooling". In this patent, the diode lead is embedded in the bending seat, and then the bending component is driven by a motor to bend the diode lead in cooperation with the bending seat. However, this bending method is prone to damage to the lead surface when the bending angle is large, thereby reducing the yield of diode leads. Utility Model Content

[0004] To address the shortcomings of existing technologies, a diode lead bending head and bending mechanism are provided to solve the problem that bending diode leads can easily cause surface damage.

[0005] On the one hand, the technical solution of this utility model to solve the above-mentioned technical problems is as follows: a diode lead bending head, comprising:

[0006] Bending the main body;

[0007] The movable component is rotatably connected to the bending body;

[0008] A pressure roller is rotatably connected to one end of the movable part, and the outer peripheral contour of the pressure roller protrudes beyond the outer contour of the corresponding end of the movable part.

[0009] An elastic reset element is disposed between the movable element and the bending body, and is used to push the pressure roller outward.

[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0011] The outer contour of the pressure roller is larger than that of the moving part, and its outer peripheral surface contacts the lead wire first. The pressure roller, which is rotatably connected to the moving part, contacts the surface of the lead wire. The pressure roller can drive the lead wire to bend during rotation, avoiding damage to the lead wire surface. At the same time, the moving part is hinged to the bending body, so that the pressure roller can swing with the moving part, leaving a deflection margin for the pressure roller. The elastic reset part can push the pressure roller toward the lead wire, ensuring that the pressure roller is in contact with the lead wire at all times during the bending process.

[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0013] In one embodiment, the movable element includes:

[0014] Two movable plates are disposed on both sides of the bending body and are hinged to the bending body. The pressure roller is rotatably connected between the two movable plates at the end away from the bending body.

[0015] A connecting piece is provided at a distance from the bending body and is connected between the two movable pieces. One end of the elastic reset member abuts against the connecting piece.

[0016] In one embodiment, the bending body has a mounting hole, and the movable part is disposed at the end of the bending body.

[0017] In one embodiment, the bottom of the bending body extends outward to form an extension portion, and the movable member is movably connected to the extension portion.

[0018] The protruding extension makes it easier to make the movable parts set on the extension protrude, so that the pressure roller on the moving machine can make priority contact with the lead wire.

[0019] On the other hand, this embodiment also discloses a diode lead bending mechanism, which includes:

[0020] The aforementioned bending head;

[0021] A slidable groove in which the bending head is slidably connected;

[0022] A drive motor is located at one end of the slide groove, and the output end of the drive motor is connected to the end of the bending head away from its pressure roller, for driving the bending head to reciprocate along the slide groove;

[0023] The wire clamping die has its side facing the bending head and the pressure roller corresponding to the opening and closing of the wire clamping die. The pressure roller is used to reciprocate along the side of the wire clamping die to push and bend the lead wire extending from that side.

[0024] The bending head is driven by a drive motor to move back and forth in the chute, which in turn causes the pressure roller on the bending head to move back and forth. During the movement, the pressure roller contacts the lead wire extending from the side of the wire clamping die, which can bend the lead wire at a 90-degree angle, resulting in good forming effect, while avoiding damage to the lead wire and improving the yield.

[0025] In one embodiment, an L-shaped bracket is also included, one end of which is connected to the side of the slide groove away from the clamping mold, and the other end is disposed on the operating table.

[0026] In one embodiment, at least one waist-shaped hole is provided on the other end of the L-shaped bracket, and the length direction of the waist-shaped hole is arranged along the direction of the clamping mold.

[0027] By setting the waist-shaped hole, the position of the L-shaped bracket, slide, and bending head can be adjusted, and the distance between them and the clamping mold can be adjusted, thus making it suitable for lead wires of different specifications and sizes.

[0028] In one embodiment, an air blowing pipe is also included, disposed above the opening of the clamping mold.

[0029] By setting up an air blowing pipe, the lead wire can be dropped after molding.

[0030] In one embodiment, limiting plates are respectively provided on both sides of the L-shaped bracket to abut against the L-shaped bracket, so as to form a limiting groove pointing towards the clamping mold, which is used to limit the fixed position of the L-shaped bracket.

[0031] In one embodiment, at least one fastening bolt is screwed through the limiting plate, and the end of the fastening bolt abuts against the L-shaped bracket. Attached Figure Description

[0044] Example 1

[0045] like Figure 1As shown, the diode lead bending head 100 provided by this utility model includes: a bending body 1, a movable part 2, a pressure roller 3, and an elastic reset part 4.

[0046] The bending body 1 is strip-shaped, and the movable part 2 is rotatably connected to the bending body 1. The movable part can then rotate around the hinge to form an oscillation. The pressure roller 3 is rotatably connected to one end of the movable part 2. Specifically, the pressure roller 3 is connected to the bottom end of the movable part 2 on the outer side, that is, on the side away from the bending body 1, to ensure that the pressure roller 3 preferentially contacts the outer surface of the lead wire. The outer circumferential contour of the pressure roller 3 protrudes from the outer contour of the corresponding end of the movable part 2 to avoid the movable part 2 scraping against the lead wire and to ensure that the pressure roller 3 is always in contact with the lead wire.

[0047] The elastic reset member 4 is disposed between the movable member 2 and the bending body 1, and is used to push the pressure roller 3 outward. By setting the elastic reset member 4, the pressure roller 3 can be pushed outward at all times, keeping the pressure roller 3 in contact with the lead wire at all times during rotation. The elastic reset member 4 can be implemented by a compression spring.

[0048] Specifically, pin holes or guide posts can be provided at the connection points between the elastic reset member 4 and the movable member 2 and the bending body 1 to fix the two ends of the elastic reset member 4.

[0049] The outer contour of the pressure roller 3 is larger than that of the movable part 2, and its outer peripheral surface contacts the lead wire first. The pressure roller 3, which is rotatably connected to the movable part 2, contacts the surface of the lead wire. The pressure roller 3 can drive the lead wire to bend during rotation, avoiding damage to the surface of the lead wire. At the same time, the movable part 2 is hinged to the bending body 1, so that the pressure roller 3 can swing with the movable part 2, leaving a deflection margin for the pressure roller 3. The elastic reset part 4 can push the pressure roller 3 toward the lead wire, ensuring that the pressure roller 3 is in contact with the lead wire at all times during the bending process.

[0050] The movable component 2 includes two movable pieces 201 and a connecting piece 202.

[0051] Two movable pieces 201 are disposed on both sides of the bending body 1. The movable pieces 201 are hinged to the bending body 1. The pressure roller 3 is rotatably connected between the two movable pieces 201 at one end away from the bending body 1, specifically located on the outer side of the bottom end of the two movable pieces 201. The connecting piece 202 is spaced apart from the bending body 1. This space is used to place the elastic reset member 4 and is connected between the two movable pieces 201. The connecting piece 202 can be integrally formed with the movable pieces 201. One end of the elastic reset member 4 abuts against the connecting piece 202.

[0052] The bending body 1 has mounting holes 5 for easy installation and positioning. The movable part 2 is located at the end of the bending body 1. The movable part 2 located at the end makes it easier to make priority contact with the lead wire.

[0053] Similarly, the bottom of the bending body 1 extends outward to form an extension 6, which is located on the end side of the bending body 1, and the movable member 2 is movably connected to the extension 6.

[0054] The protruding extension 6 makes it easier to protrude the movable part 2 provided on the extension 6, so that the movable pressure roller 3 on the machine can contact the lead wire first.

[0055] Example 2

[0056] like Figure 2 As shown, this embodiment also discloses a diode lead bending mechanism, which includes: the bending head 100, the slide groove 200, the drive motor 300 and the wire clamping mold 400 in embodiment 1.

[0057] The bending head 100 is slidably connected in the chute 200. Specifically, the bending body 1 of the bending head 100 is matched in the chute 200 and fixed to the slider in the chute 200 through the mounting hole 5 on the bending body 1. The drive motor 300 is set at one end of the chute 200. The chute 200 is vertical. The drive motor 300 is set at the top of the chute 200. The output end of the drive motor 300 is connected to the end of the bending head 100 away from its pressure roller 3. Specifically, since the bending head 100 is connected to the slider in the chute 200, the output end of the drive motor 300 is connected to the slider, thereby driving the bending head 100 to move up and down, that is, to move back and forth along the chute 200.

[0058] The side of the opening of the wire clamping mold 400 is correspondingly arranged with the pressure roller 3 of the bending head 100, that is, the circumferential surface of the pressure roller 3 is tangent to the side of the wire clamping mold 400 near the pressure roller 3. Then, a gap is reserved between the pressure roller 3 and the side of the wire clamping mold 400 to allow the lead wire to exist. The pressure roller 3 is used to move back and forth along the side of the wire clamping mold 400 to push and bend the lead wire extending from the side.

[0059] The bending head 100 is driven by the drive motor 300 to move back and forth in the slide 200, which in turn enables the pressure roller 3 on the bending head 100 to move back and forth. During the movement, the pressure roller 3 contacts the lead wire extending from the side of the wire clamping die 400, which can bend the lead wire at a 90-degree angle, resulting in good forming effect, while avoiding damage to the lead wire and improving the yield.

[0060] In this embodiment, an L-shaped bracket 500 is also included. One end of the L-shaped bracket 500 is connected to the side of the slide groove 200 away from the wire clamping mold 400, and the other end is set on the operating table. That is, the vertical end of the L-shaped bracket 500 is connected and fixed to the back of the slide groove 200, and the horizontal end of the L-shaped bracket 500 is fixed on the operating table.

[0061] Specifically, at least one waist-shaped hole 600 is provided on the other end of the L-shaped bracket 500. The L-shaped bracket 500 is fixed on the worktable by fasteners cooperating with the waist-shaped hole 600. The waist-shaped hole 600 is set along the length direction pointing towards the clamping mold 400.

[0062] By setting the waist-shaped hole 600, the position of the L-shaped bracket 500, the slide 200, and the bending head 100 can all be adjusted, and the distance between them and the clamping mold 400 can be adjusted, thus making it suitable for lead wires of different specifications and sizes.

[0063] To restrict the movement direction of the L-shaped bracket, limiting plates 800 are respectively provided on both sides of the L-shaped bracket 500 to abut against the L-shaped bracket 500, forming limiting grooves pointing towards the wire clamping mold 400. This is used to restrict the fixed position of the L-shaped bracket 500, so that the L-shaped bracket 500 can only move in the direction of approaching or moving away from the wire clamping mold 400, thereby adjusting the gap between the pressure roller 3 and the wire clamping mold 400.

[0064] At least one fastening bolt 900 is screwed through the limiting plate 800. The end of the fastening bolt 900 abuts against the L-shaped bracket 500. After the fastening bolt 900 is tightened, it abuts against the side of the L-shaped bracket 500, fixing the L-shaped bracket 500 in the limiting groove.

[0065] In this embodiment, an air blowing pipe 700 is also included, which is disposed above the opening of the wire clamping mold 400. The opening of the air blowing pipe 700 can be fixed above the opening of the wire clamping mold 400 by means of wire or the like, and connected to an external air source to supply air to the opening of the wire clamping mold 400. By setting the air blowing pipe 700, the lead wire after forming can be dropped.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
