Description

Technical Field

[0001] This utility model relates to the field of household appliance manufacturing technology, and in particular to a bundling device for the production of household appliance wiring harnesses. Background Technology

[0002] Household appliance wiring harnesses are a complete cable assembly composed of multiple independent wires and cables, which are combined through bundling, wrapping, and splicing. Inside household appliances such as refrigerators, washing machines, air conditioners, and televisions, they are responsible for transmitting power and signals, connecting power supplies, control boards, sensors, motors, and other components to work together. In order to neatly fix the scattered wires and prevent the risk of short circuits or detachment caused by friction and pulling, the wiring harnesses need to be bundled during production. However, existing bundling machines rely heavily on manual winding of wire harnesses, have low automation levels, and thus low efficiency. When tools are used for assistance, demolding is difficult, and the bundled wire harnesses often get stuck, making them difficult to remove and easily damaging. At the same time, manual operation also leads to unstable bundling quality, inconsistent tightness, and safety hazards such as hand injuries from mechanical clamping. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bundling device for the production of wire harnesses for household appliances.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figure 3 - Figure 4 As shown, this utility model provides a technical solution: a bundling device for producing wire harnesses for household appliances, including a bundling mechanism 2. The bundling mechanism 2 includes a cylinder 21. A receiving box 22 is provided at one end of the cylinder 21. A protective cover 23 is provided on one side of the receiving box 22. The receiving box 22 and the protective cover 23 are connected by a mounting buckle 24. A protective shell 25 is provided at the end of the receiving box 22 away from the cylinder 21. The protective shell 25 is connected to the receiving box 22 through a rotating shaft 265. A motor 26 is provided inside the receiving box 22. A fixing frame 262 is provided on one side of the motor 26. The end of the fixing frame 262 away from the motor 26 is connected to the receiving box 22. A turntable 261 is provided at one end of the motor 26. A pull rod 263 is provided at the end of the turntable 261 away from the motor 26. A connecting rod 264 is provided at the end of the pull rod 263 away from the turntable 261. A rotating shaft 265 is provided at the end of the 264 furthest from the pull rod 263. A support plate 266 is provided in the middle of the rotating shaft 265. A gear 267 is provided at the end of the support plate 266 furthest from the pull rod 263. Gear 267 is engaged with gear 268. A motor 269 is provided on one side of gear 268. A connecting plate 251 is provided at the end of the rotating shaft 265 furthest from the pull rod 263. A connecting block 252 is provided at the end of the connecting plate 251 furthest from the rotating shaft 265. Two connecting rods 253 are provided inside the connecting block 252. The connecting rods 253 are symmetrically distributed about the rotating shaft 265. A limit frame 254 is provided at the end of the connecting rods 253 furthest from the connecting block 252.

The limit rollers 255 are arranged in a linear equidistant array.

[0019] In this embodiment, one end of the household appliance wiring harness to be bundled is snapped into the snap ring 256. The second motor 269 is started, rotating the second gear 268. Simultaneously, the first gear 267, snapped with the second gear 268, starts rotating. The rotation of the second gear 268 drives the rotating shaft 265 to rotate, causing the protective shell 25 connected to the rotating shaft 265 to rotate, thus winding the household appliance wiring harness onto the limiting frame 254. After winding, the cylinder 21 is activated, pushing the receiving box 22 to the bundling machine 1 for bundling. After bundling, the receiving box 22 is retracted. After retraction, the first motor 26 is activated, rotating the turntable 261 and the connection point of the pull rod 263 to move, causing... Pull rod 263 moves backward, pulling shaft 265 backward. Shaft 265 pulls connecting plate 251 to pull connecting block 252. Connecting block 252 pulls connecting rod 253 to straighten. When connecting rod 253 is straightened, two sets of limiting brackets 254 approach each other, reducing the tension on the wire harness and making it easier to remove the wire harness. The entire wire bundling mechanism 2 completes the wire bundling and binding operations, greatly improving production efficiency and realizing assembly line operation. By bringing the two limiting brackets 254 closer to each other, the tension on the wire harness is reduced, realizing the demolding of the wire harness and solving the problem of difficult wire removal by limiting bracket 254. In addition, the protective cover of receiving box 22 is connected by mounting buckle 24, which facilitates subsequent maintenance operations.
