Description

Technical Field

[0001] The present application relates to the field of wire harness technology, and in particular to a wire harness terminal installation device. Background Art

[0002] The wiring harness is the network backbone of a car's electrical circuits; without it, there would be no automotive circuits. A wiring harness is a component that connects electrical wires and cables, formed by pressing contact terminals (connectors) stamped from copper, and then plastic-molded with insulation or a metal casing. The wiring harness industry chain encompasses wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wiring harnesses are widely used in automobiles, home appliances, computers and communications equipment, and various electronic instruments. The vehicle body wiring harness connects the entire vehicle body.

[0003] During the production of wire harnesses, terminals need to be installed at the ends of the wire harnesses. When installing the terminals, the terminals need to be first put on the edge of the wire harness, and then the terminals are squeezed through the wire harness installation device to fix the terminals at the ends of the wire harnesses.

[0004] The above-mentioned prior art solution has the following defects: when squeezing the terminal, the worker needs to hold the wire harness and place the end of the wire harness in the device, which may cause the device to injure the worker's fingers, posing a safety hazard. Utility Model Content

[0005] In order to make workers safer when installing terminals, the present application provides a wiring harness terminal installation device.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A wire harness terminal installation device includes a base, a transmission structure and an extrusion structure. The transmission structure includes a driving wheel, a conveyor belt and a driven wheel. The driving wheel and the driven wheel are rotatably connected to a side surface of the base. The driving wheel and the driven wheel are driven by the conveyor belt. Multiple clamping structures are arranged on the surface of the conveyor belt. The extrusion structure is arranged above the base.

[0008] By adopting the above solution, workers can place the wire with the end on the clamping structure of the conveyor belt, and then the active wheel drives the conveyor belt to move so that the end reaches the extrusion structure, and then the extrusion structure squeezes the end, so that the end is fixed to the end of the wire, so that the worker is outside the extrusion structure, thereby reducing the impact of the extrusion structure on the worker's safety, and making the worker safer when installing the terminal.

[0009] Optionally, the extrusion structure includes a driving member, an upper pressing tool and a lower pressing tool, the lower pressing tool is connected to the upper surface of the base, the driving member is connected to the upper pressing tool, and the driving member can drive the upper clamp to move up and down.

[0010] By adopting the above solution, when the terminal reaches between the upper pressing tool and the lower pressing tool, the driving member drives the upper pressing tool to move downward, thereby squeezing the terminal so that the terminal is fixedly connected to the end of the wire harness.

[0011] Optionally, there are multiple lower pressing tools, and multiple upper pressing tools are provided, and the multiple upper pressing tools are connected to the driving member.

[0012] By adopting the above solution, when the driving member drives the upper pressing tool to move downward, multiple terminals can be squeezed at the same time, thereby improving the production efficiency of the wire harness.

[0013] Optionally, the lower pressing tool is connected to a second cylinder that drives the lower pressing tool to move up and down.

[0014] By adopting the above solution, when the end head is squeezed, the driving member drives the upper press to move downward, and the second cylinder drives the lower press to move upward, thereby squeezing the end head. Compared with only the upper press moving downward, the upper and lower presses move at the same time, which can better squeeze the end head and avoid bending the end head.

[0015] Optionally, the clamping structure includes an upper clamp and a lower clamp, the lower clamp is connected to the conveyor belt, a guide rod is fixedly connected to the side of the lower clamp facing away from the conveyor belt, the upper clamp is slidably connected to the guide rod, and a spring is arranged between the upper clamp and the lower clamp, the base is connected to a guide plate on one side of the conveying structure, a raised block is fixedly connected under the guide plate, the edge of the raised block is smoothly connected to the guide plate, and the upper clamp is connected to a sliding rod, and when the upper clamp moves to the bottom of the guide plate, the sliding rod abuts against the lower surface of the guide plate.

[0016] By adopting the above solution, when the clamping structure moves to the edge of the conveyor belt, the sliding rod abuts against the lower surface of the guide plate, and the upper clamp and the lower clamp are in an open state. At this time, the worker can place the wire between the upper clamp and the lower clamp. When the clamping structure moves to the middle position of the conveyor belt, the sliding rod abuts against the surface of the raised block, and the upper clamp and the lower clamp are in a clamping state, thereby clamping the wire, and then the wire is squeezed by the extrusion structure to avoid displacement of the wire and extrusion errors during terminal extrusion.

[0017] Optionally, the sliding rod is rotatably connected to a roller.

[0018] By adopting the above solution, the friction between the slide bar and the guide plate is reduced, so that the relative movement of the slide bar and the guide plate is smoother.

[0019] Optionally, a positioning groove is provided on one side of the lower clamp and the upper clamp close to the extrusion structure, and when the wiring harness is placed on the lower clamp, the edge of the terminal is located in the positioning groove.

[0020] By adopting the above solution, workers can place the terminals more quickly, thereby improving the production efficiency of the wiring harness.

[0021] Optionally, an inclined plate is provided at one end of the conveying structure, the inclined plate is inclined downward away from the end of the conveying structure, and a collection box is provided below the inclined plate.

[0022] By adopting the above solution, the wires with the terminals installed can enter the collection box along the inclined plate, so that the wires are automatically collected, saving manpower.

[0023] In summary, this application has the following technical effects:

[0024] 1. A conveying structure is provided to keep workers away from the extrusion structure, making it safer for workers when installing terminals;

[0025] 2. The clamping structure is set to avoid installation errors caused by terminal movement during terminal installation;

[0026] 3. The inclined plate and collection box are provided to automatically collect the wires after the terminal is installed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2A wiring harness terminal installation device includes a base 1, a conveying structure and an extrusion structure. The conveying structure includes a driving wheel 2, a conveyor belt 21 and a driven wheel 22. The driving wheel 2 and the driven wheel 22 are rotatably connected to a side surface of the base 1. The driving wheel 2 is connected to a driving structure. The driving wheel 2 and the driven wheel 22 are driven by the conveyor belt 21. A plurality of clamping structures 5 are provided on the surface of the conveyor belt 21. The extrusion structure is provided above the base 1. When terminal installation is required, workers can place the wire with the end on the clamping structure 5 of the conveyor belt 21. Then the driving wheel 2 drives the conveyor belt 21 to move so that the end reaches the extrusion structure. Then the extrusion structure squeezes the end so that the end is fixed to the end of the wire, so that the worker is not squeezed out of the extrusion structure, thereby reducing the impact of the extrusion structure on the worker's safety, making it safer for the worker to install the terminal.

[0034] Reference Figure 2 The extrusion structure includes a first cylinder 3 and a second cylinder 4. The first cylinder 3 is fixedly connected to the top of the base 1, and the piston rod of the first cylinder 3 is vertically downward. The piston rod of the first cylinder 3 is fixedly connected to a plurality of upper presses 31, and a molding groove for extruding the terminal is provided on the lower surface of the upper press 31. The second cylinder 4 is arranged above the base 1, and the piston rod of the second cylinder 4 is upward. The second cylinder 4 is located below the first cylinder 3. The piston rod of the second cylinder 4 is fixedly connected to a plurality of lower presses 41, and a molding groove for extruding the terminal is provided on the upper surface of the lower press 41. When the terminal moves between the upper press 31 and the lower press 41, the first cylinder 3 extends to drive the upper press 31 to move downward, and the second cylinder 4 extends to drive the lower press 41 to move upward, thereby pressing the terminal tightly against the end of the wire. The simultaneous movement of the first cylinder 3 and the second cylinder 4 toward the terminal can prevent the terminal from bending and causing damage to the terminal.

[0035] Reference Figure 3 and Figure 4 The clamping structure 5 includes an upper clamp 51 and a lower clamp 52. The lower clamps are provided with multiple, and the multiple lower clamps 52 are arranged on the outer surface of the transmission belt. A guide rod 521 is fixedly connected to the side of the lower clamp 52 away from the conveyor belt 21. The upper clamp 51 is slidably connected to the guide rod 521, and a spring 522 is sleeved on the guide rod 521. The two ends of the spring 522 are respectively fixedly connected to the upper clamp 51 and the lower clamp 52. Circular holes are provided on the adjacent surfaces of the upper clamp 51 and the lower clamp 52, and a positioning groove is provided on the side of the upper clamp 51 close to the upper press 31, and a positioning groove is provided on the side of the lower clamp 52 close to the lower press 41. When the upper clamp 51 and the lower clamp 52 are closed, the end of the terminal is located in the positioning groove, so that the staff can place the terminal in the desired position more quickly and accurately.

[0036] Reference Figure 1 and Figure 3The base 1 is fixedly connected to a guide plate 6, which is arranged between the clamping structure 5 and the extrusion structure. A protrusion 61 is provided in the middle position of the lower surface of the guide plate 6, and the edge of the protrusion 61 is smoothly connected to the guide plate 6. The upper clamp 51 is fixedly connected to a slide rod 511, and the end of the slide rod 511 is fixedly connected to a roller 512. When the upper clamp 51 is located below the guide plate 6, the roller 512 abuts against the lower surface of the guide plate 6. When the upper clamp 51 is located below the protrusion 61, the roller 512 abuts against the lower surface of the protrusion, and at this time the upper clamp 51 and the lower clamp 52 are closed. When installing the wiring harness terminal, when the upper clamp 51 moves to the edge of the guide plate 6, the worker places the wires and terminals on top of the lower clamp 52, and then the transmission belt drives the clamp to move. When the upper clamp 51 moves to the raised block 61, the upper clamp 51 and the lower clamp 52 are closed, thereby clamping the wiring harness terminal. Then the upper press 31 and the lower press 41 squeeze the terminal, and then the transmission belt continues to drive the upper clamp 51 and the lower clamp 52 to move until they move to the edge of the guide plate 6, and the upper clamp 51 and the lower clamp 52 are opened, so that the wires and terminals can be taken out.

[0037] Reference Figure 1 An inclined plate 7 is provided on one side of the conveyor belt 21. The inclined plate 7 is fixedly connected to the base 1, and the inclined plate 7 is inclined downward away from the conveyor belt 21. A collecting box 8 is provided below the inclined plate 7. When the wires with terminals installed reach the inclined plate 7, the wires automatically slide along the inclined plate 7 into the collecting box 8, thereby realizing automatic collection of the wires and saving labor.

[0038] The specific implementation principle of the present application is as follows: when the terminal needs to be installed, the worker puts the wire with the terminal between the upper clamp 51 and the lower clamp 52 on one side of the conveyor belt 21, and then the transmission belt drives the upper clamp 51 and the lower clamp 52 to move, and then when the upper clamp 51 moves to the protruding block 61, the upper clamp 51 and the lower clamp 52 close, thereby clamping the wiring harness terminal, and then the upper press 31 and the lower press 41 squeeze the terminal, and then the transmission belt continues to drive the upper clamp 51 and the lower clamp 52 to move until they move to the edge of the guide plate 6, the upper clamp 51 and the lower clamp 52 open, and then the wire contacts the inclined plate 7, and then the wire moves along the inclined plate 7 to the collection box 8 to be collected. The present application enables workers to install wiring harness terminals more safely by keeping them away from the squeezing structure.

[0039] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
