Description

Technical Field

[0001] The utility model relates to the field of decorative lamp production and manufacturing, in particular to a lamp wire stripping mechanism for LED lamp string production equipment. Background Art

[0002] Traditional leather wire light strings rely on manual production, which is too inefficient. The Chinese patent with publication number CN113513713A discloses a fully automatic disc-type leather wire light string production device and its production method, including a disc clamping and conveying mechanism and a wire mechanism, a cutting mechanism, a peeling mechanism, a chip welding module and a glue injection mechanism arranged in sequence around the disc clamping and conveying mechanism. The disc clamping and conveying mechanism is used to clamp the leather wire and intermittently convey the leather wire in a circular route. The wire mechanism is used to guide the leather wire into the disc clamping and conveying mechanism. The cutting mechanism is used to cut the leather wire. The peeling mechanism is used to press down the cut leather wire to expose the copper wire in the leather wire. The chip welding module is used to weld the chip to the copper wire. The glue injection mechanism is used to inject glue into the copper wire so that the chip can be encapsulated. The production device and production method of this invention can realize the fully automatic production of leather wire light strings, which is efficient and convenient, and saves labor costs.

[0003] However, the above-mentioned production device for leather-line light strings still has the following problems:

[0004] 1) The stripping of the wire of the skin-line lamp needs to be completed by the cutting mechanism and the stripping mechanism. The cutting mechanism and the stripping mechanism work independently, which is equivalent to two separate processes, resulting in a longer processing cycle;

[0005] 2) For different leather-wire lamps, the diameter of the copper wire may be different, and the thickness of the cut by the automatic cutter in the cutting mechanism needs to match the diameter of the copper wire. However, the cutting mechanism in the above-mentioned leather-wire lamp string production device makes it difficult to adjust the thickness of the automatic cutter when cutting;

[0006] 3) The stripping mechanism of the above-mentioned production device for the leather wire light string realizes stripping by pressing downward. Since the tightness of different leather wires may be inconsistent when clamping, the problem of inconsistent stripping length will occur. Utility Model Content

[0007] The purpose of the present utility model is to provide a lamp wire stripping mechanism for LED lamp string production equipment to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0020] Furthermore, the transverse transmission module includes a second crank-connecting rod mechanism connected to the third transmission member.

[0021] Furthermore, the transverse transmission module also includes a third crank-connecting rod mechanism connected to the second crank-connecting rod mechanism; the cutter transverse transmission assembly also includes a second adjusting member, which is adjustable in position and arranged on the second crank-connecting rod mechanism.

The automatic cutter assembly cuts the leather wire, the cutter cutting transmission assembly drives the automatic cutter assembly to complete the cutting action, and the cutter transverse transmission assembly drives the automatic cutter assembly to move transversely along the forward direction of the leather wire, so that the automatic cutter assembly peels the leather wire from the copper wire after cutting the leather wire.

[0032] Continue reading Figure 1-Figure 2 In one embodiment of the present invention, the automatic cutting assembly includes a first cutting module, a second cutting module, and a linkage member 1. The linkage member 1 is rotatably arranged, and its ends are respectively rotatably connected to the first cutting module and the second cutting module. The cutting drive assembly is connected to the first cutting module, and the first and second cutting modules are synchronously moved in opposite directions through the linkage member 1 to complete the cutting operation. In addition, the cutting drive assembly can also be connected to the second cutting module to directly drive the second cutting module.

[0033] Continue reading Figure 1 and Figure 2 In one embodiment of the present utility model, the first cutting module includes a first cutting body 2 and a first transmission member 4 connected to the first cutting body 2, the second cutting module includes a second cutting body 3 and a second transmission member 5 connected to the second cutting body 3, the first cutting body 2 and the second cutting body 3 are arranged opposite to each other up and down, and the two ends of the linkage member 1 are respectively rotatably connected to the first transmission member 4 and the second transmission member 5.

[0034] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the automatic cutting assembly further includes a first mounting base 6, the middle portion of the linkage member 1 is rotatably connected to the first mounting base 6, and the first transmission member 4 and the second transmission member 5 are respectively vertically slidably connected to the two sides of the first mounting base 6.

[0035] Continue reading Figure 1 and Figure 2In one embodiment of the present invention, the first mounting seat 6 is provided with limit members 7 on the upper and lower sides respectively, and the limit members 7 limit the rotation range of the linkage member 1, thereby limiting the maximum distance between the first cutter body 2 and the second cutter body 3.

[0036] Specifically, if Figure 2 As shown, the stopper 7 is specifically a stopper plate. When the linkage member 1 rotates counterclockwise and drives the first cutter body 2 and the second cutter body 3 to the maximum distance apart, the linkage member 1 engages the stopper plate 7. Therefore, during the design and production stages of the present invention, the maximum distance between the first cutter body 2 and the second cutter body 3 can be changed by adjusting the upper and lower mounting positions of the stopper 7.

[0037] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the cutter cutting transmission assembly further includes a first adjusting member 8, which is adjustable on the knife holder of the first cutter body 2. When the first cutter body 2 and the second cutter body 3 move to the minimum distance between them, the first adjusting member 8 is engaged with the knife holder of the second cutter body 3. The first adjusting member 8 adjusts the minimum distance between the first cutter body 2 and the second cutter body 3 by changing the installation position.

[0038] Specifically, the first adjusting member 8 is a screw, which is vertically screwed to the tool holder of the first cutter body 2. By rotating the first adjusting member 8, its vertical installation position on the tool holder can be adjusted, thereby adjusting the minimum distance between the first cutter body 2 and the second cutter body 3, and then matching leather wires of different sizes.

[0039] In other embodiments of the present invention, the first adjusting member 8 may also be disposed on the second cutting module.

[0040] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the cutter cutting transmission assembly is a first crank-connecting rod mechanism, which includes a first crank 13 and a first connecting rod 14. The first crank 13 is rotatably arranged, and the first connecting rod 14 is vertically arranged, and its two ends are universally connected to the first crank 13 and the first transmission member 4 through fisheye joints.

[0041] When the automatic cutter assembly and the cutter cutting transmission assembly are working, the first crank 13 receives external power to rotate, thereby driving the first connecting rod 14 to move up and down. The first connecting rod 14 drives the first transmission member 4 and the first cutter body 2 to move up and down. The first transmission member 4 drives the second transmission member 5 and the second cutter body 3 to move up and down through the linkage member 1. The movement directions of the first cutter body 2 and the second cutter body 3 are opposite. The cutting and loosening actions are completed by the approach and separation of the first cutter body 2 and the second cutter body 3.

The second mounting base 12 is fixed, and the third transmission member 9 is a rod-shaped structure that is laterally slidably mounted on the second mounting base 12 and connected to the first mounting base 6 of the automatic cutter assembly. The transverse transmission module is connected to the third transmission member 9 to drive the third transmission member 9 to move transversely.

[0043] Among them, the second crank-connecting rod mechanism includes a second crank 15 and a second connecting rod 16, and the third crank-connecting rod mechanism includes a third crank 17 and a third connecting rod 18. The third crank 17 and the second crank 15 are rotatably arranged, and the third connecting rod 18 is vertically arranged, and its upper and lower ends are universally connected to the second crank 15 and the third crank 17 through fisheye joints respectively. The second connecting rod 16 is horizontally arranged, and its two ends are universally connected to the second crank 15 and the third transmission member 9 through fisheye joints respectively.

[0044] When the cutter transverse movement transmission assembly is working, the third crank 17 receives external power to rotate, which drives the third connecting rod 18 to move up and down, and the third connecting rod 18 drives the second crank 15 to swing. The second crank 15 drives the second connecting rod 16 together with the third transmission member 9 to move forward and backward, and the third transmission member 9 drives the automatic cutter assembly to move forward and backward.

[0045] Continue reading Figure 2 In one embodiment of the present invention, the cutter transverse movement transmission assembly also includes a second adjusting member 10, which is adjustable on the second crank 15. When the second crank 15 rotates counterclockwise to the extreme position, the second adjusting member 10 is engaged with the fixed structure 11, and the second adjusting member 10 limits the range of movement of the second crank-connecting rod mechanism and the transverse movement range of the automatic cutter assembly, thereby limiting the stripping length of the leather wire.

[0046] Specifically, the second adjusting member 10 is preferably a screw threadedly connected to the second crank 15. By rotating the second adjusting member 10, its vertical installation position on the second crank 15 can be adjusted, thereby adjusting the movable range of the second crank-connecting rod mechanism and the lateral movement range of the automatic cutting assembly, and then adjusting the stripping length of the leather wire.
