Description

Technical Field

[0001] This utility model relates to the technical field of lantern processing equipment, and more specifically, to a wire fixing fixture for lantern equipment. Background Technology

[0002] In the production and processing of decorative lights (such as festival string lights), one of the key processes is to crochet the wire into a wavy shape (such as...). Figure 3 (As shown), this allows for the subsequent connection of LED beads at or near the crest of the wave, with each wavy section twisted into a spiral shape. During the "hooking" and "twisting" processes, reliable positioning and fixing of the wire are crucial. Existing processing methods often lack efficient fixing devices specifically designed for this process, or the existing fixing devices are complex and bulky, making them unsuitable for the dense arrangement and continuous processing requirements of automated production lines. If the fixing is unstable, the wire is prone to slippage during the hooking operation using the pull claw and lever, resulting in irregular wave shapes or dimensional deviations, which in turn affects the welding quality of subsequent LED beads and the overall aesthetics of the product.

[0003] Therefore, how to provide a fixing fixture that is simple in structure, compact in size, and can efficiently and firmly clamp wires is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The present invention provides a wire fixing fixture for a lighting equipment. Its structure is simple and compact, and it can automatically clamp the wire using the principle of elastic reset. It can solve the problems of inconvenient and inefficient wire fixing in the prior art when used with automated equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wire fixing fixture for a decorative lighting equipment includes a guide cylinder, a slide rod, a pressure plate, a drive end block, and a spring; The slide rod is coaxial and slides through the guide cylinder; the pressure plate is fixedly disposed at one end of the slide rod, and the driving end block is disposed at the other end of the slide rod; a wire clamping area for clamping the wire is formed between the pressure plate and the end of the guide cylinder. The guide cylinder has a spring mounting groove at one end facing the drive end block. The spring is sleeved on the slide rod and located in the spring mounting groove. One end of the spring abuts against the bottom of the spring mounting groove, and the other end abuts against the drive end block. Under the elastic force of the spring, the pressure plate tends to move towards the guide cylinder to clamp the wire.

[0006] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses a coaxial design of guide cylinder, slide rod and spring, and uses the restoring force of spring to pull slide rod, so that pressure plate and guide cylinder end face form a closed clamping state under normal conditions. This structure is extremely simple and compact, occupies little space, and is very suitable for dense installation on the circulating conveying device of colored lantern processing. In the wire hooking process, the wire can be firmly pressed by the spring force to prevent the wire from slipping during hooking; when it is necessary to release the wire, the external mechanism only needs to push the drive end block to overcome the spring force, the operation response speed is fast, and the production efficiency and processing quality are greatly improved.

[0007] (2) By designing the drive end block to be adjustable in position on the slide rod, the initial distance between the pressure plate and the guide cylinder (the size of the wire clamping area) can be finely adjusted according to different specifications (thickness) of wire. This increases the versatility of the fixture, allowing the same set of fixtures to be adapted to the production of different models of decorative lights, and reducing mold costs. The guide cylinder, pressure plate and other components adopt a circular or square cross-section design, which is convenient for processing and manufacturing, and reduces the manufacturing cost of the fixture. (1) This utility model achieves the normal clamping and force-activated opening functions of the wire through the coaxial design of the guide cylinder, slide rod and spring. At the hooking station, the pressure plate can be quickly opened by pushing the drive end block with external force, and the wire is hooked and put in with the help of the equipment; after the external force is removed, the spring's restoring force automatically presses the hooked wire into shape. This structure ensures that the wire is always in a stable clamped state during the process of conveying from the hooking station to the twisting station, and during the twisting operation, effectively preventing the wire from slipping and deforming, and ensuring the yield rate of the colored lanterns.

[0008] (2) By designing the drive end block to be adjustable in position on the slide bar, the initial size of the wire clamping area can be finely adjusted according to the diameter of the colored light wire, thus enhancing the versatility of the fixture. The guide cylinder, pressure plate and other components adopt a circular or square cross-section design, which is simple in structure, easy to process and manufacture, and reduces production costs.

[0009] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0010] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0014] Please refer to Figure 1 and Figure 2 This embodiment provides a wire fixing fixture for a decorative lighting device, including a guide cylinder 1, a pressure plate 2, a spring 3, a drive end block 4, and a slide rod 6.

[0015] The guide cylinder 1 is used to fix the circulating conveyor of the colored lantern processing equipment. The slide rod 6 is coaxial and slides through the guide cylinder 1. One end of the slide rod 6 (the upper end in the figure) is fixedly provided with a pressure plate 2, and the other end (the lower end in the figure) is provided with a drive end block 4. A wire clamping area 5 (a groove structure in this embodiment) is formed between the pressure plate 2 and the upper end face of the guide cylinder 1. This wire clamping area 5 is used to accommodate and clamp the wire 8.

[0016] A spring mounting groove 7 is provided at one end of the guide cylinder 1 facing the drive end block 4, and the slide rod 6 passes through the spring mounting groove 7. The spring 3 is sleeved on the slide rod 6 and located in the spring mounting groove 7. One end of the spring 3 abuts against the bottom of the spring mounting groove 7, and the other end abuts against the drive end block 4. Under the action of the natural elastic force (restoring force) of the spring 3, the drive end block 4 tends to move away from the guide cylinder 1, thereby pulling the slide rod 6 to move the pressure plate 2 towards the guide cylinder 1, so that the wire clamping area 5 is in a closed clamping state.

[0017] To accommodate wires of different thicknesses, the drive end block 4 and the slide bar 6 are detachably connected, and the axial position of the drive end block 4 on the slide bar 6 is adjustable (e.g., by threaded adjustment or fixing in different positions with a set screw). By adjusting the position of the drive end block 4, the limit position of the pressure plate 2 in the clamping state can be changed, thereby adjusting the initial size (clamping gap) of the wire clamping area 5.

[0018] like Figure 1As shown, in this embodiment, the cross-sections of the guide cylinder 1, pressure plate 2, drive end block 4, and slide rod 6 are all circular. In other alternative embodiments, the structures of the above components can also be square or other geometric shapes, which does not affect the realization of their core functions.

[0019] Please combine Figure 3 This embodiment describes the working process of the fixture on an automated production line for colored lights. Several fixtures are typically installed in a group on a circulating synchronous conveyor (such as a turntable or conveyor belt), passing sequentially through the thread-hooking station and the twisting station according to the process. The fixture is also used in conjunction with an external drive device installed at a specific station (such as the thread-hooking station), such as a linear actuation structure (cylinder or push rod).

[0020] Wire-laying station (opening and fixing): When the fixture moves to the wire hooking station with the conveyor, the linear actuation structure configured at the station moves toward the fixture and pushes the drive end block 4. The drive end block 4 overcomes the elastic force of the spring 3 and drives the slide rod 6 and the pressure plate 2 to move away from the guide cylinder 1 (upward in the figure), thereby opening the wire clamping area 5.

[0021] At this point, the device's pull claws and lever engage in a hooking operation, hooking wire 8 into a shape as shown. Figure 3 The shape shown is wavy.

[0022] After the hooking action is completed, the linear toggle mechanism retracts and no longer pushes the drive end block 4. The spring 3 releases its elastic force, pushes the drive end block 4 to reset, pulls the pressure plate 2 downward, and firmly presses the wire 8, which has just completed the hooking shape, onto the end face of the guide cylinder 1.

[0023] Conveying process (keeping clamped): The fixture leaves the hooking station and moves to the next station. During this process, since no external force is applied to the drive end block 4, the fixture remains in a clamped state under the action of spring force, ensuring that the wavy shape of the wire 8 does not deform or slip.

[0024] Twisting station (stable support): When the fixture reaches the twisting station, it remains clamped. At this time, the twisting mechanism rotates and twists the wavy part (usually the crest) of the wire. Because the pressure plate 2 provides a continuous and stable clamping force under the action of the spring 3, the root of the wire 8 is firmly fixed, which can effectively resist the torque generated during twisting, ensure that the twist shape is regular, and prevent subsequent wires from shifting.

[0025] Material cutting or subsequent processes: After processing is completed, the drive end block 4 is pushed again at the unloading position by a top-pushing mechanism similar to the hook-and-wire station to open the pressure plate 2, and the processed wire can be taken out.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
