Description

Technical Field

[0001] This utility model relates to the field of wire harness production and processing, and in particular to a feeding device for wire harness production and processing. Background Technology

[0002] A wire harness is an integrated assembly consisting of multiple insulated wires, cables, shielded wires, etc., arranged in a specific direction and layout, along with accessories such as terminals, connectors, sheaths, and bundling devices. It is widely used in the automotive, electronic equipment, and aerospace industries. Its core function is to enable signal transmission, power supply, and circuit connection between different components. Through standardized integrated design, it simplifies the installation process, reduces wiring clutter, and improves space utilization.

[0003] During wire harness production, the wire harnesses need to be conveyed and fed. Chinese Patent CN220222508U discloses a feeding device for electronic wire harness production, relating to the field of electronic wire harness manufacturing technology. This feeding device includes a conveyor belt with baffles on both sides, a steering device above the conveyor belt, and a feeding mechanism on the conveyor belt, including a mounting plate. This feeding device uses the conveyor belt to carry the electronic wire harness into the cable tray. Contact between the wire harness and the contacts causes the feeding machine to move downwards. During this movement, the motor is shut off by the combined action of a spring, a control block, and a motor switch, ensuring the conveyor belt does not operate during feeding. However, the above patent requires the wire harness to contact the contacts and then the motor to shut off through the combined action of a spring, control block, and motor switch to control the motor's operation. Therefore, controlling the motor's shutdown is cumbersome and requires frequent motor control via the motor switch, which can easily lead to frequent motor starts and stops and damage.

[0004] In response to this practical problem encountered in wire harness production, there is an urgent need to design a new feeding device for wire harness production and processing. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding device for wire harness production and processing, which solves the problems of existing feeding devices having cumbersome components for controlling the motor to stop operation and requiring frequent motor control via a motor switch, which easily leads to damage due to frequent motor start-stop. It also solves the problem of wire harness misalignment during traditional feeding processes. The intermittent drive mechanism of this invention achieves intermittent motion through mechanical transmission. The drive motor drives the drive shaft and drive wheel to rotate. Utilizing the matching relationship between the drive protrusion and the transmission recess on the transmission disc, combined with the limiting effect of the arc-shaped hole, the conveyor belt can operate smoothly and intermittently without the need for frequent motor switch control, thus avoiding the risk of damage caused by frequent motor start-stop.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: A feeding device for wire harness production and processing includes two L-shaped support plates 1. The device is characterized by: a conveyor belt 2 installed inside the two L-shaped support plates 1; a plurality of equally spaced silicone positioning seats 3 fixedly connected to the outer surface of the conveyor belt 2; an intermittent drive mechanism 5 fixedly installed on one side of each L-shaped support plate 1; bearing rings 14 embedded in each of the two L-shaped support plates 1; and drive rollers 13 connected at both ends to the inner rings of the two bearing rings 14 respectively; a fixing plate 8 fixedly installed on one side of each L-shaped support plate 1; an electric cylinder 9 fixedly installed on the bottom surface of the fixing plate 8; a lifting slide plate 10 fixedly installed at the telescopic end of the electric cylinder 9; a supporting plate 6 fixedly connected to the upper surface of the lifting slide plate 10; and a wire harness terminal crimping mechanism 7 fixedly installed at the top of the supporting plate 6.

[0007] The supporting plate 6 has two limiting sliding holes 11 on one side, and the sliding frame 12 is slidably connected to the inner wall of the two limiting sliding holes 11. One side of the sliding frame 12 is fixedly connected to one side of the fixing plate 8.

[0008] The intermittent drive mechanism 5 includes a fixed support plate 51, which is fixedly installed on one side of the L-shaped support plate 1. A drive motor 52 is fixedly installed on one side of the fixed support plate 51. A drive shaft 53 is fixedly installed at the output end of the drive motor 52. A drive wheel 54 is fixedly installed on the outer surface of the drive shaft 53. A drive protrusion 57 is provided on the outer surface of the drive wheel 54.

[0009] One end of the drive roller 13 is fixedly mounted with a transmission disk 55. The outer surface of the transmission disk 55 is provided with annularly arranged transmission recesses 56, and the drive protrusion 57 is adapted to the transmission recesses 56. The outer surface of the transmission disk 55 is provided with annularly arranged arc-shaped holes 59, and the inner wall of one of the arc-shaped holes 59 is in contact with the outer surface of the drive wheel 54.

[0010] A bearing ring 58 is fixedly embedded on one side of the fixed support plate 51, and the outer surface of the drive shaft 53 is fixedly connected to the inner ring of the bearing ring 58.

[0011] The bottom surfaces of the two L-shaped support plates 1 are fixedly connected to two support frames 15. The interiors of the two adjacent silicone positioning seats 3 are provided with wire harnesses 4, and the outer surfaces of the wire harnesses 4 are in close contact with the inner walls of the silicone positioning seats 3. Multiple support rollers 17 are installed on the side of the two L-shaped support plates 1 that are close to each other, and the outer surfaces of the support rollers 17 are rotatably connected to the inner side of the conveyor belt 2.

[0012] A controller 16 is fixedly installed on one side of the L-shaped support plate 1.

[0013] The beneficial effects of this invention are as follows: The silicone positioning seats, evenly spaced on the conveyor belt surface, can support wire harnesses. The structural design of the silicone positioning seats in close contact with the wire harnesses avoids the wire harness misalignment problem during traditional feeding, facilitating subsequent processing. The intermittent drive mechanism achieves intermittent motion through mechanical transmission. The drive motor drives the drive shaft and drive wheel to rotate. Utilizing the matching relationship between the drive protrusion and the transmission recess on the transmission disc, combined with the limiting effect of the arc-shaped hole, the conveyor belt operates smoothly and intermittently, eliminating the need for frequent motor switching and avoiding the risk of damage caused by frequent motor starts and stops. After the silicone positioning seats reach the designated position, the conveyor belt stops, and the electric cylinder pushes the lifting slide to precisely process the wire harness terminal crimping mechanism. After processing, it quickly resets and conveys the next workpiece, forming an automated cyclic operation, improving feeding and processing efficiency. Attached Figure Description

[0017] 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 only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. To make the above-mentioned objects, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] See Figures 1 to 5 As shown, the feeding device for wire harness production and processing of this utility model includes two L-shaped support plates 1, a conveyor belt 2 installed inside the two L-shaped support plates 1, and a plurality of equally spaced silicone positioning seats 3 fixedly connected to the outer surface of the conveyor belt 2. An intermittent drive mechanism 5 is fixedly installed on one side of the L-shaped support plate 1. Bearing rings 14 are embedded in both L-shaped support plates 1, and the two ends of the drive roller 13 are respectively connected to the inner rings of the two bearing rings 14. A fixing plate 8 is fixedly installed on one side of the L-shaped support plate 1, an electric cylinder 9 is fixedly installed on the bottom surface of the fixing plate 8, a lifting slide plate 10 is fixedly installed on the telescopic end of the electric cylinder 9, a supporting plate 6 is fixedly connected to the upper surface of the lifting slide plate 10, and a wire harness terminal crimping mechanism 7 is fixedly installed on the top of the supporting plate 6. Mechanism 7 includes a crimping mold, a guide assembly, and a pressure sensor. After the support plate 6 drives the mechanism to align, the electric cylinder 9 drives the mold to descend. The guide assembly ensures alignment accuracy. The mold applies pressure to the terminals of the wire harness 4 inside the silicone positioning seat 3 for crimping. The pressure sensor provides feedback parameters. After completion, the mold moves upward to reset, adapting to the intermittent conveying rhythm. The conveyor belt 2 serves as the conveying carrier, working in conjunction with the silicone positioning seat 3 on its outer surface to achieve orderly carrying of the wire harness 4. The silicone positioning seat 3 is in close contact with the wire harness 4 to prevent deviation during conveying. The drive roller 13 provides power transmission to the conveyor belt 2, and the bearing ring 14 reduces its rotational friction. The fixing plate 8 fixes the electric cylinder 9, and the electric cylinder 9 drives the lifting slide plate 10 to lift and lower the support plate 6, enabling the wire harness terminal crimping mechanism 7 to accurately align and process.

[0019] Two limiting sliding holes 11 are provided on one side of the support plate 6. The sliding frame 12 is slidably connected to the inner wall of the two limiting sliding holes 11. One side of the sliding frame 12 is fixedly connected to one side of the fixed plate 8. The limiting sliding holes 11 cooperate with the sliding frame 12 to improve the lifting stability and ensure the processing accuracy.

[0020] The intermittent drive mechanism 5 includes: a fixed support plate 51 fixed to the side of the L-shaped support plate 1; a drive motor 52 fixedly mounted on one side of the fixed support plate 51; the drive motor 52 is a worm gear reducer motor with a power of 0.75-5.5kW; a drive shaft 53 fixedly mounted on the output end of the drive motor 52; a drive wheel 54 fixedly mounted on the outer surface of the drive shaft 53; a drive protrusion 57 provided on the outer surface of the drive wheel 54; a transmission disk 55 fixedly mounted on one end of the drive roller 13; and a transmission recess 56 arranged in annular pattern on the outer surface of the transmission disk 55, with the drive protrusion 57 matching the transmission recess 56. The outer surface of the transmission disc 55 has annularly arranged arc-shaped holes 59. The inner wall of one of the arc-shaped holes 59 contacts the outer surface of the drive wheel 54. A bearing ring 58 is fixedly embedded on one side of the fixed support plate 51. The outer surface of the drive shaft 53 is fixedly connected to the inner ring of the bearing ring 58. The fixed support plate 51 provides a stable mounting base for the drive motor 52. The drive motor 52 outputs power to drive the drive shaft 53 to rotate. The bearing ring 58 reduces the rotational resistance of the drive shaft 53 and extends its service life. The drive shaft 53 drives the drive wheel 54 to rotate. The drive protrusion 57 is adapted to the transmission concave hole 56 of the transmission disc 55 to realize power transmission. The arc-shaped hole 59 cooperates with the drive wheel 54 to realize intermittent rotation, so that the conveyor belt 2 runs precisely and intermittently, ensuring that the wire harness 4 stops at the processing position without displacement and improving the continuity of processing.

[0021] Two L-shaped support plates 1 are fixedly connected to two support frames 15 on their bottom surfaces. Two silicone positioning seats 3 are equipped with wire harnesses 4 inside, and the outer surface of the wire harnesses 4 is in close contact with the inner wall of the silicone positioning seats 3. Multiple support rollers 17 are installed on the side of the two L-shaped support plates 1 that are close to each other, and the outer surface of the support rollers 17 is rotatably connected to the inner side of the conveyor belt 2. A controller 16 is fixedly installed on one side of the L-shaped support plate 1. The support frames 15 enhance the overall support strength of the L-shaped support plates 1 and prevent shaking when the device is running. The support rollers 17 support the conveyor belt 2, reduce the deformation of the conveyor belt 2 under load, and ensure smooth conveying. The controller 16 realizes the coordinated control of various components.

[0022] See Figures 1 to 5As shown, when using the wire harness production and processing feeding device of this utility model, before operation, the wire harness 4 is placed in the silicone positioning seats 3 arranged at equal intervals on the surface of the conveyor belt 2. The silicone positioning seats 3 are in close contact with the wire harness 4 to achieve positioning. After the device is started, the controller 16 issues a command, and the intermittent drive mechanism 5 on one side of the L-shaped support plate 1 starts to work, which can drive the conveyor belt 2 to move intermittently, so that the silicone positioning seats 3 carrying the wire harness 4 are transported one by one to the bottom of the wire harness terminal crimping mechanism 7. When the silicone positioning seat 3 reaches the designated position, the electric cylinder 9 starts and pushes the lifting slide plate 10 to adjust the height. Then the wire harness terminal crimping mechanism 7 completes the processing of the wire harness 4. After the processing is completed, the electric cylinder 9 resets, and the intermittent drive mechanism 5 continues to start, which can transport the next silicone positioning seat 3 to the processing position, and the feeding processing is completed in a cycle. The intermittent drive mechanism 5 operates as follows: the drive shaft 53 at the output end of the drive motor 52 drives the drive wheel 54 on its outer surface to rotate. The drive protrusion 57 on the outer surface of the drive wheel 54 is adapted to the transmission recess 56 on the transmission disk 55 at one end of the drive roller 13. When the drive protrusion 57 is inserted into the transmission recess 56, it drives the transmission disk 55 and the drive roller 13 to rotate. The drive roller 13 achieves stable rotation, thereby driving the conveyor belt 2 to run. When the drive protrusion 57 disengages from the transmission recess 56, the outer surface of the drive wheel 54 contacts the inner wall of the arc-shaped hole 59 of the transmission disk 55. At this time, the transmission disk 55 stops rotating, and the conveyor belt 2 stops, forming intermittent motion.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made to this utility model should be included within the protection scope of this utility model.
