Technical Field

[0001] This invention belongs to the field of wire harness welding technology, and specifically relates to a welding fixture for wire harnesses that facilitates terminal replacement. Background Technology

[0002] Wire harness terminal welding connects wires to terminals (metal connectors) using high temperature or mechanical energy, forming a permanent connection that is electrically reliable, mechanically strong, and resistant to vibration and oxidation. It is widely used in the automotive, aerospace, electronic equipment, and industrial control industries.

[0003] Existing welding fixtures are mostly ultrasonic welding machines. By changing the welding head, it is easy to weld different types of terminals, which facilitates type change welding. However, existing type change welding fixtures cannot remove moisture from the wire harness wires that are gathered together at the end of the wire harness. The presence of moisture will seriously affect the connection between the wire harness wires and the terminal, resulting in poor welding effect.

[0004] Therefore, it is necessary to invent a welding fixture that facilitates the replacement of terminal wire harnesses to solve the above problems. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] This invention provides a welding fixture for easy-to-change terminal wire harnesses, such as... Figures 1 to 4As shown, it includes: equipment body 1, support platform 2, clamping plate 3, welding torch 4, drive platform 5, and fully drying assembly; The equipment body 1 is used for wire harness welding. The equipment body 1 is an ultrasonic welding machine in the prior art. The support platform 2 is set on the equipment body 1 to support the wire harness and terminals. The clamping plates 3 are symmetrically set on the equipment body 1 to hold the terminals. The clamping plates 3 are the same as the clamping plates on the ultrasonic welding machine in the prior art. Their specific working principle is the prior art and will not be described in detail here. The welding gun 4 is set above the support platform 2 and is used for wire harness welding. The welding gun 4 is the welding gun on the ultrasonic welding machine in the prior art. The welding gun 4 can be replaced according to the size of the terminal. The replacement operation is the same as the welding gun replacement operation on the ultrasonic welding machine in the prior art and will not be described in detail here. By replacing the welding gun 4, it is easier to weld the terminals of different types. The drive platform 5 is set on the equipment body 1 and is used to drive the welding gun 4 to move in the vertical direction. The drive platform 5 is the drive platform on the ultrasonic welding machine in the prior art that can move the welding gun up and down. The drying component is set on the equipment body 1 and is used to dry the wire harness wires in the wire harness.

[0020] In use, the terminal is placed on the support platform 2 and clamped by a pair of clamps 3. Then, the wire harness ends are dried by the drying assembly to remove moisture from the wire harness. The wire harness is then placed on the terminal, and the welding gun 4 is lowered by the drive platform 5 to weld the wire harness to the terminal. By removing moisture trapped in the wire harness, the welding quality is prevented from being affected by moisture, thus ensuring the welding effect.

[0021] like Figures 1 to 4 As shown, the fully drying assembly includes: a partition plate 6, a housing 7, an air outlet 8, a connecting pipe 9, a heat source device (not shown in the diagram), a connecting plate 10, and a finishing assembly; Divider plates 6 are equidistantly arranged above support platform 2. Divider plates 6 have internal channels. Divider plates 6 are made of iron. Housing 7 fixes multiple divider plates 6 together and is connected to the channels. Air outlets 8 are equidistantly arranged on both sides of divider plates 6 and are connected to the channels. Connecting pipe 9 is fixedly connected to the bottom of housing 7 and is connected to the inside of housing 7. Heat source equipment is placed on the ground and is connected to connecting pipe 9 to inject hot air into the inside of connecting pipe 9. The heat source equipment is a hot air blower that can provide hot air at 60-80 degrees Celsius in the prior art. Connecting plate 10 is used to fix housing 7 to equipment body 1. Organizing component is placed in front of divider plates 6 and is used to organize the ends of wire harnesses.

[0022] Hot air is injected into the connecting pipe 9 through a heat source device. The temperature range of the hot air is between 60 and 80 degrees Celsius. The hot air is blown out through the housing 7, the channel, and the air outlet 8, which heats the partition plate 6 and generates continuous hot air. The wire harness ends are inserted from top to bottom between multiple partition plates 6. The multiple partition plates 6 separate the wire harness ends that were originally gathered together. The heat of the partition plates 6 themselves and the hot air generated can dry the moisture trapped inside the wire harness ends. After 30 seconds, the wire harness ends are horizontally pulled out from the partition plates 6. Then, the wire harness ends are tidied up by the tidying component so that the wire harness ends can be reset and gathered together to avoid affecting subsequent welding.

[0023] like Figure 3 As shown, a wire-pulling plate 11 is fixedly installed on the top of the partition plate 6. The wire-pulling plate 11 is triangular in shape, with its tip pointing upwards.

[0024] Insert the wire harness into the pointed tip of the wire-pulling plate 11 so that the wire harness can be pried open slightly. Then push the wire harness downward so that the wire harness can be separated along the wire-pulling plate 11. Therefore, the wire-pulling plate 11 makes it easier to separate the wire harness.

[0025] like Figure 3 As shown, the sorting components include: carrier plate 12, sorting plate 14, extension plate 23, drive component, and support component; The carrier plate 12 is positioned in front of the partition plate 6, and the sorting plates 14 are symmetrically positioned on the top of the carrier plate 12 for clamping and sorting the ends of the wire harness. The extension plate 23 is fixedly connected to the outside of the carrier plate 12 for placing the wire harness shell. The drive assembly is positioned on the carrier plate 12 for driving the movement of the pair of sorting plates 14 toward each other. The support assembly is positioned on the support platform 2 for supporting the carrier plate 12.

[0026] After the dried wire harness is pulled out from the separator plate 6, the wire harness shell is placed on the extension plate 23. At this time, the wire harness is located between a pair of sorting plates 14. Pressing down the wire harness causes the carrier plate 12 and the sorting plate 14 to descend. The drive assembly drives the pair of sorting plates 14 to move closer to each other, so that the separated wire harness can be clamped and reset from both sides. After the wire harness is reset, the support assembly drives the carrier plate 12 to reset. Conversely, the drive assembly works in the opposite direction to reset the pair of sorting plates 14.

[0027] like Figure 3 As shown, the support assembly includes: a support rod 15, a spring 16, and a limiting block 17; Support rods 15 are symmetrically fixedly installed on the top of support platform 2. Carrier plate 12 is slidably sleeved on the outside of support rods 15. Spring 16 is sleeved on the outside of support rods 15 to support carrier plate 12. Limiting block 17 is fixedly installed on the top of support rods 15.

[0028] When the carrier plate 12 is pressed down, the carrier plate 12 descends along the support rod 15 to compress the spring 16, and the pressure on the carrier plate 12 is released. The spring 16 then carries the carrier plate 12 up to reset.

[0029] like Figure 3 As shown, the drive assembly includes: lead screw 13, gear 18, and rack 19; The lead screw 13 is rotatably mounted on the top of the carrier plate 12. Specifically, the top of the carrier plate 12 is provided with a horizontal groove, and the lead screw 13 is rotatably mounted in the horizontal groove. The sorting plate 14 is threadedly connected to the lead screw 13. The lead screw 13 is symmetrically provided with threads on the outside, and the threads on both sides are arranged in opposite directions. The gear 18 is fixedly mounted on one end of the lead screw 13, and the rack 19 is fixedly mounted on the top of the support platform 2. The rack 19 meshes with the gear 18.

[0030] The lower pressure plate 12, along with the lead screw 13, the sorting plate 14, and the gear 18, descends. The gear 18 rotates along the rack 19 in the forward direction, thereby rotating the lead screw 13. This, in conjunction with the thread, drives a pair of sorting plates 14 to move closer to each other. When the plate 12 rises to reset, conversely, the gear 18, rack 19, and lead screw 13 can drive a pair of sorting plates 14 to move away from each other and reset.

[0031] like Figure 4 As shown, cable management plates 20 are equidistantly arranged on the top of the housing 7, and a rotating assembly is provided on the top of the housing 7. The rotating assembly can drive multiple cable management plates 20 to rotate between adjacent partition plates 6.

[0032] As the wire harness passes through multiple wire-drawing plates 11 from top to bottom, some of the wire harness will bend upwards due to friction, causing these wire harnesses to be unable to move to the air outlet 8 and thus not be able to fully contact the hot air, affecting the drying effect. Therefore, after the wire harness is moved between the partition plates 6, the rotating assembly drives multiple wire management plates 20 to rotate between adjacent partition plates 6. As the wire management plates 20 move, the bent wire harness can be straightened and this part of the wire harness is sent into the air outlet 8, so that the wire harness can be fully dried and the drying effect can be improved.

[0033] like Figure 4 As shown, the rotating assembly includes: a rotating rod 21, a side plate, and a torsion spring 22; The rotating rod 21 is used to fix and connect multiple wire management plates 20. The side plates are symmetrically fixed and installed on the top of the housing 7. The rotating rod 21 is rotatably installed between a pair of side plates. The torsion spring 22 is sleeved on one end of the rotating rod 21 that extends to the outside of the side plate. The two ends of the torsion spring 22 are fixedly connected to the side plate and the rotating rod 21 respectively. The thickness of the partition plate 6 is the same as that of the wire drawing plate 11.

[0034] Rotating the lever 21 causes it to rotate along with the cable management plate 20 toward the gap between the adjacent partition plates 6. The torsion spring 22 is torsionally deformed. The cable management plate 20 first enters the gap between the adjacent wire-pulling plates 11, and then pulls the bent cable bundle into the air outlet 8. Releasing the lever 21 resets the torsion spring 22, thereby resetting the lever 21 and the cable management plate 20, so that the cable management plate 20 is in a vertical state and leaves the partition plate 6 and the wire-pulling plate 11.

[0035] like Figure 4 As shown, the width of the cable management plate 20 is the same as the gap width between the adjacent partition plates 6.

[0036] This allows the cable management plate 20 to guide the bent cable bundle located between the wire drawing plates 11 toward the air outlet 8.

[0037] like Figure 3 As shown, the top of the extension plate 23 is located below the top of the carrier plate 12.

[0038] This allows the wire harness to be positioned between a pair of tidying plates 14 after the wire harness shell is placed on the extension plate 23.

[0039] Working principle: In use, the terminals are placed on the support platform 2 and clamped by a pair of clamping plates 3. Hot air is injected into the connecting pipe 9 through a heat source device. The temperature range of the hot air is between 60-80 degrees Celsius. The hot air is blown out through the housing 7, the channel, and the air outlet 8, which heats the partition plate 6 and generates continuous hot air. The wire harness ends are inserted from top to bottom into multiple wire pulling plates 11, and then enter the space between the partition plates 6. The partition plates 6 separate the wire harness wires that were originally gathered together. The heat of the partition plates 6 and the hot air generated by them can dry the moisture trapped inside the wire harness wires. After 30 seconds, the wire harness wires are horizontally pulled out from the partition plates 6. After the dried wire harness wires are pulled out from the partition plates 6, the wire harness housing is placed on the extension plate 23. At this time, the wire harness wires are located between a pair of sorting plates 14. Pressing down on the wire harness causes the carrier plate 12, the lead screw 13, the sorting plate 14, and the teeth to be pulled out. As wheel 18 descends, gear 18 rotates forward along rack 19, thereby rotating lead screw 13. This, in conjunction with the threaded drive, moves a pair of sorting plates 14 closer together, allowing the separated wire harness strands to be clamped and reset from both sides. When the carrier plate 12 is pressed down, it descends along support rod 15 to compress spring 16. After the wire harness strands are reset, the pressure on carrier plate 12 is released, and spring 16 moves carrier plate 12 upward to reset. Conversely, in conjunction with gear 18, rack 19, and lead screw 13, the pair of sorting plates 14 can be driven to move away from each other to reset. By sorting and resetting the ends of the wire harness, the wire harness strands can be reset and gathered together, avoiding affecting subsequent welding. Then, the dried and sorted wire harness is placed on the terminal. The welding gun 4 is driven down by drive table 5 to weld between the wire harness strands and the terminal. By removing moisture trapped in the wire harness strands, the welding quality is avoided, ensuring the welding effect. As the wire harness passes through multiple wire-drawing plates 11 from top to bottom, some of the wire harness will bend upwards due to friction, causing these wire harnesses to be unable to move to the air outlet 8 and thus not be able to fully contact the hot air, affecting the drying effect. Therefore, after moving the wire harness between the partition plates 6, the rotating rod 21 is rotated to make it rotate with the wire guiding plate 20 to the gap between the adjacent partition plates 6. The torsion spring 22 is torsionally deformed. The wire guiding plate 20 first enters the gap between the adjacent wire guiding plates 11, and then the bent wire harness is guided into the air outlet 8. The rotating rod 21 is released, and the torsion spring 22 is reset, thereby resetting the rotating rod 21 and the wire guiding plate 20, so that the wire guiding plate 20 is in a vertical state and leaves the partition plate 6 and the wire guiding plate 11. By straightening and resetting the wire harness so that it is located at the air outlet 8, the wire harness can be fully dried, improving the drying effect.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
