Description

Technical Field

[0001] This utility model belongs to the field of heading machine technology, specifically relating to a small secondary feeding mechanism. Background Technology

[0002] Diode leads are external devices, mainly used as pins on electronic components, transistors, CPU motherboards or circuit boards. Leads come in various types, including T-type, L-type, PIN, and round-headed leads.

[0003] Currently, when copper wire is fed to the forming mechanism for impact extrusion forming, it is usually fed in conjunction with a clamping mechanism. However, in some guide pin forming equipment that requires continuous impact on the end of the copper wire to form it, the existing wire feeding mechanism often cannot gradually feed the copper wire forward for impact forming by the impact head at the forming mechanism. For example, the patent with announcement number CN216881502U describes a secondary pushing mechanism, which transmits the driving force of the drive cam to one end of the cylinder rod mechanism at the end through a transmission mechanism arranged on the side of the heading machine. The other end of the cylinder rod mechanism then pushes the slider in the heading machine to feed the wire a second time.

[0004] However, this device requires a long transmission mechanism and cylinder rod mechanism to be installed on the machine base, which not only makes the overall mechanism complex, but also makes the overall mechanism large in size and occupies a lot of space. Utility Model Content

[0005] To address the shortcomings of existing technologies, a small secondary feeding mechanism is provided to solve the problems of complex structure and large space occupation of previous secondary feeding mechanisms.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A small secondary feeding mechanism, comprising:

[0007] A first slider is slidably connected to the machine base along a first direction, and a first wire clamping mold is provided in the first slider;

[0008] A feed piece is mounted on the first slider, and one side of the feed piece is continuously provided with several stepped surfaces;

[0009] The second slider is slidably connected to the machine base along the first direction, and the second slider is provided with a second wire clamping mold corresponding to the first wire clamping mold;

[0010] A shift fork is rotatably mounted on one side of the first and second sliders. The first end of the shift fork abuts against the stepped surface, and the second end abuts against the second slider. It is used to push the second slider forward when the first slider moves backward.

[0011] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0012] The first wire clamping mold on the first slider clamps the lead wire for primary wire feeding. Based on the primary wire feeding achieved by the first slider, the first slider and the second slider are linked by a shift fork. When the first slider retracts, the stepped surface on the feed piece drives the shift fork to rotate, which in turn pushes the second slider forward through the second end of the shift fork. The second wire clamping mold on the second slider achieves secondary wire feeding. The overall structure is simple, requiring only the addition of a shift fork and a feed piece on the first slider. Moreover, the shift fork is small in size and occupies little space on the heading machine.

[0013] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0014] In one embodiment, a reset member is provided on the side of the second slider away from the first slider, and the reset member abuts against the second slider to push the second slider toward the first slider.

[0015] By setting a reset component, the second slider, after completing the second feeding, is pushed back to its original position near the first slider, making it easier for the next second feeding to continue.

[0016] In one embodiment, the stepped surface on the feed piece is gradually raised toward the direction of the second slider.

[0017] The stepped surface on the feeding section is designed to be gradually raised, so that as the feeding section moves away from the second slider as the first slider moves away from the second slider, the gradually raised stepped surface can gradually push the shift fork to rotate and move closer to the second slider, thereby pushing the second slider away from the first slider to achieve secondary feeding.

[0018] In one embodiment, a roller is rotatably disposed on the first end of the shift fork, and the circumferential surface of the roller abuts against the stepped surface.

[0019] By setting rollers, the contact friction between the shift fork and the feed segment on the first slider is reduced, making the shift fork rotate more smoothly.

[0020] In one embodiment, an adjusting screw is screwed onto the second end of the shift fork, with the end of the adjusting screw facing the second slider, and a pad is provided on the second slider near the second end of the shift fork.

[0021] In one embodiment, a guiding device is further included, the guiding device comprising:

[0022] A guide rod is provided along a first direction, and the first slider and the second slider are slidably connected to the guide rod;

[0023] Two fixed seats are located outside the first slider and the second slider, respectively, and the two ends of the guide rod are connected to the fixed seats.

[0024] In one embodiment, a limiting mechanism is further included, the limiting mechanism comprising:

[0025] An abutment block is installed on one side of the first slider;

[0026] Two limiting seats are spaced apart on both sides of the abutment block along the first direction to limit the movement range of the first slider.

[0027] In one embodiment, a limiting screw is screwed onto the limiting seat, with the end of the limiting screw facing the abutment block. Attached Figure Description

[0041] like Figure 1-3 As shown, the present invention provides a small secondary feeding mechanism, which includes: a first slider 1, a second slider 5, a feeding section 3, and a shift fork 7.

[0042] The first slider 1 is slidably connected to the machine base 18 along the first direction. The first slider 1 is provided with a first wire clamping mold 2. Specifically, the first direction is the direction in which the lead wire 17 is fed forward. The lead wire 17 is clamped in the first wire clamping mold 2 and is fed forward by the first slider 1 moving along the first direction.

[0043] The first slider 1 can reciprocate along the first direction through a swing arm wire feeding mechanism in the heading machine, such as the patent with publication number CN216487996U, a diode lead 17 swing arm wire feeding mechanism, which connects the bottom of the first slider 1 to the connecting rod at the second end of the swing arm rod, and drives the first slider 1 to reciprocate through the connecting rod.

[0044] The feed plate 3 is installed on the first slider 1. Several stepped surfaces 4 are continuously provided on one side of the feed plate 3. The feed plate 3 is detachably connected to the first slider 1 and is fixed to the top of the first slider 1 by bolts. By replacing different feed plates 3, the stepped surfaces 4 on the different feed plates 3 are set differently to meet the needs of different secondary feed lines.

[0045] The second slider 5 is slidably connected to the machine base 18 along the first direction. The second slider 5 is provided with a second wire clamping mold 6 corresponding to the first wire clamping mold 2. The second slider 5 is spaced apart from the first slider 1 and is located on the right side of the first slider 1. After the first slider 1 finishes feeding the wire, it continues to complete the secondary wire feeding. The second wire clamping mold 6 has the same structure as the first wire clamping mold 2, and the wire is unidirectional in both wire clamping molds. The packaging wire can be fed forward to the right.

[0046] The middle part of the shift fork 7 is rotatably mounted on one side of the first slider 1 and the second slider 5. The first end of the shift fork 7 abuts against the stepped surface 4, and the second end abuts against the second slider 5. The shift fork 7 links the first slider 1 and the second slider 5. The shift fork 7 is used to push the second slider 5 forward when the first slider 1 moves backward. Specifically, the first end of the shift fork 7 is mounted on a base of several stepped surfaces 4. When the first slider 1 moves the feed piece 3, the first end of the shift fork 7 contacts different stepped surfaces 4, causing the shift fork 7 to rotate, thereby pushing the second slider 5 at the second end of the shift fork 7 to move forward. Specifically, the middle part of the shift fork 7 is rotatably connected to the heading machine base 18 through a shaft 15. A lifting cylinder 16 is sleeved on the shaft 15 to control the shift fork 7 and the feed piece 3 to be at the same horizontal height.

[0047] The first wire clamping mold 2 on the first slider 1 clamps the lead wire 17 for one wire feeding. Based on the one wire feeding achieved by the first slider 1, the first slider 1 and the second slider 5 are linked by the shift fork 7. When the first slider 1 moves backward, the step surface 4 on the feed piece 3 drives the shift fork 7 to rotate, and then the second end of the shift fork 7 continues to push the second slider 5 forward. The second wire clamping mold 6 on the second slider 5 achieves a second wire feeding. The overall structure is simple, and it can be achieved by adding only the shift fork 7 and the feed piece 3 on the first slider 1. Moreover, the shift fork 7 is small in size and occupies little space on the heading machine table 18.

[0048] A reset member 8 is provided on the side of the second slider 5 away from the first slider 1. The reset member 8 abuts against the second slider 5 and is used to push the second slider 5 toward the first slider 1. The reset member 8 can be implemented by a spring, and the spring force is used to push the second slider 5 to always move closer to the first slider 1.

[0049] By setting the reset component 8, the second slider 5, after completing the second feeding, is pushed back to its original position near the first slider 1, so that the second feeding can continue next time.

[0050] Specifically, such as Figure 3 As shown, the stepped surface 4 on the feed section 3 gradually rises toward the direction of the second slider 5.

[0051] The stepped surface 4 on the feeding plate 3 is set to be gradually raised, so that when the feeding plate 3 moves away from the second slider 5 as the first slider 1 moves away from the second slider 5, the gradually raised stepped surface 4 can gradually push the shift fork 7 to rotate and approach the second slider 5, thereby pushing the second slider 5 away from the first slider 1 to achieve secondary feeding.

[0052] Specifically, the connecting surface of the step surface 4 is an inclined slope, which makes it easier for the first end of the shift fork 7 to move back and forth between multiple step surfaces 4.

[0053] To ensure that the first end of the shift fork 7 can smoothly abut against the feed piece 3, a roller 10 is rotatably provided on the first end of the shift fork 7. The roller 10 is connected to the first end of the shift fork 7 by a rod-like member such as a bolt, and the circumferential surface of the roller 10 abuts against the stepped surface 4.

[0054] By setting the roller 10, the contact friction between the shift fork 7 and the feed segment 3 on the first slider 1 is reduced, making the shift fork 7 rotate more smoothly.

[0055] In this embodiment, an adjusting screw 11 is screwed onto the second end of the shift fork 7. The end of the adjusting screw 11 faces the second slider 5. A pad 12 is provided on the second slider 5 near the second end of the shift fork 7. The adjusting screw 11 can adjust the length of its extension by rotating, thereby changing the distance between it and the second slider 5, realizing the diversification of secondary wire feeding. At the same time, the pad 12 provided corresponding to the adjusting screw 11 can avoid excessive wear.

[0056] In this embodiment, a guide device 13 is also included. The guide device 13 is used to control the sliding direction of the first slider 1 and the second slider 5. The guide device 13 includes a guide rod 131 and two fixed seats 132.

[0057] The guide rod 131 is arranged along the first direction, and the first slider 1 and the second slider 5 are slidably connected to the guide rod 131 to ensure that the reciprocating movement direction of the first slider 1 and the second slider 5 is accurate; two fixed seats 132 are fixed at intervals on the machine base 18 of the heading machine, and the two fixed seats 132 are respectively located outside the first slider 1 and the second slider 5, clamping the two sliders between the two fixed seats 132, and the two ends of the guide rod 131 are connected to the fixed seats 132.

[0058] In this embodiment, one end of the reset member 8 abuts against the second slider 5, and the other end abuts against the fixed seat 132 near the second slider 5;

[0059] The reset component 8 is provided with a guide rod 9, which is fixed to the fixed seat 132 near the second slider 5 to ensure that the retraction direction of the reset component 8 will not be deviated.

[0060] In this embodiment, in order to control the displacement range of the first slider 1, a limiting mechanism 14 is also provided. The limiting mechanism 14 includes: an abutment block 141 and two limiting seats 142.

[0061] An abutment block 141 is installed on one side of the first slider 1, and two limiting seats 142 are spaced apart on both sides of the abutment block 141 along the first direction to limit the movement range of the first slider 1.

[0062] Furthermore, a limiting screw 143 is screwed onto the limiting seat 142, with the end of the limiting screw 143 facing the abutment block 141. The distance between the end of the limiting screw 143 and the abutment block 141 can be adjusted by the limiting screw 143, thereby controlling the displacement range of the first slider 1.

[0063] 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.
