[0017] The present invention provides an automotive wiring harness terminal welding device, the advantages of which include:

[0018] 1. By setting up a wire harness feeding mechanism and controlling the motor to start, the actuating plate can swing. When the actuating column installed inside the actuating plate enters the limiting groove opened inside the actuating rod, it can drive the actuating rod to swing, causing the rotating shaft to rotate. Under the action of the swing rod and the connecting rod, the clamping block can move back and forth between the two baffles, so that the clamping block can move the wire harness clamping mechanism directly below the welding head. Then, the welding head can be used to weld the wire harness. After the welding is completed, the motor is controlled to continue to rotate, so that the clamping block can move the wire harness clamping mechanism away from below the welding head.

[0019] 2. By setting up a wire harness clamping mechanism, as the snap-fit ​​block moves toward the welding head, the placement block can gradually approach the wedge block. Since one side of the placement block is set with an inclined surface, when the inclined surface of the placement block contacts the wedge surface of the wedge block, the wedge block can move upward, thereby allowing the movable sleeve to gradually retract into the interior of the fixed sleeve. Under the action of the second spring, the wedge surface of the wedge block can be tightly fitted with the inclined surface of the placement block, thereby stably pressing the welding wire harness against the interior of the positioning groove, realizing automatic clamping of the welding wire harness.

[0020] 3. By setting up a terminal welding feeding mechanism, the welding table is driven to move away from the welding head under the action of the wire harness feeding mechanism. This can move the welding terminals stored inside the terminal storage box to the top surface of the welding table and inside the two guide frames. Then, during the retraction of the welding table, the belt moves and moves the welding terminals inside the folding plate towards the electromagnet. When one side of the welding terminal contacts the other side of the electromagnet, or when the welding terminal is close to the electromagnet, the electromagnet can attract the welding terminal and fix it, thus achieving the purpose of automatic feeding of welding terminals.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-10This invention provides a technical solution: an automotive wiring harness terminal welding device, including a main unit 1, a wiring harness terminal welding mechanism 2 provided on the top surface of the main unit 1, the wiring harness terminal welding mechanism 2 including a stand 201, the stand 201 being fixedly installed on the top surface of the main unit 1, a crossbeam 202 being fixedly installed on the top surface of the stand 201, a guide rail 203 being installed inside the crossbeam 202, a cylinder 204 being provided outside the guide rail 203, a welding head 205 being installed at the output end of the cylinder 204, and a placement box 6 and a placement box 7 being placed on the top surface of the main unit 1 respectively. By setting the placement box 6 and the placement box 7, the welding wiring harness 5 after welding and the welding wiring harness 5 before welding can be placed separately, which can improve the convenience of welding.

[0035] The top surface of the main unit 1 is provided with a wire harness feeding mechanism 3, the inside of the wire harness feeding mechanism 3 is provided with a wire harness clamping mechanism 4, the inside of the wire harness clamping mechanism 4 holds a welding wire harness 5, and the inside of the wire harness clamping mechanism 4 is provided with a terminal welding feeding mechanism 8.

[0036] During operation, the wire harness 5 to be welded is first placed inside the wire harness clamping mechanism 4, and then multiple welding terminals 9 are neatly stacked inside the terminal welding feeding mechanism 8. Then, the wire harness feeding mechanism 3 is controlled to drive the wire harness clamping mechanism 4, which contains the wire harness 5, to move directly below the welding head 205. At this time, the cylinder 204 is controlled to drive the welding head 205 to weld the wire harness 5 and the welding terminals 9, thereby achieving the purpose of quickly welding the wire harness 5 and the wire harness clamping mechanism 4.

[0037] The wire harness feeding mechanism 3 includes a mounting plate 301, which is fixedly mounted on the top surface of the main unit housing 1. An L-shaped frame 302 is fixedly mounted on the top surface of the mounting plate 301. A connecting frame 303 is fixedly connected to one side of the L-shaped frame 302. Two baffles 304 are fixedly mounted on the top surface of the connecting frame 303. A locking block 305 is movably engaged between the two baffles 304. The wire harness clamping mechanism 4 is located above the baffles 304. A mounting block 306 is fixedly connected to one end of the mounting plate 301. A rotating shaft 307 is rotatably mounted inside the mounting block 306. Mounting block 312 is fixedly installed on one side of L-shaped frame 301. A rotating shaft 313 is rotatably mounted inside mounting block 312. Mounting block 314 is fixedly installed on one side of L-shaped frame 302. A rotating shaft 315 is rotatably mounted inside mounting block 314. A swing arm 311 is fixedly installed at the bottom end of rotating shaft 307. A swing arm 316 is fixedly sleeved on the outer surface of rotating shaft 313. A connecting arm 317 connects swing arm 316 and swing arm 311. A swing rod 318 is fixedly sleeved on the outer surface of rotating shaft 315. One end of the swing rod 318... A connecting rod 319 is connected to the locking block 305. A motor 309 is fixedly installed on the top surface of the mounting plate 301. A bevel gear 310 is fixedly connected to the output end of the motor 309. A bevel gear 308 is fixedly installed on the outer surface of the rotating shaft 307. The bevel gear 308 and the bevel gear 310 mesh with each other. A toggle plate 323 and a sector frame 322 are fixedly sleeved on the outer surface of the rotating shaft 313. An arc plate 320 and a toggle rod 321 are fixedly sleeved on the outer surface of the rotating shaft 315. A toggle post 324 is fixedly installed inside the toggle plate 323. The inside of 21 has a limiting groove, the size of which corresponds to the size of the actuating column 324. The fan-shaped frame 322 fits against the arc surface of the arc plate 320. When the rotating shaft 313 rotates under the swing of the swing arm 316, it can synchronously drive the fan-shaped frame 322 to swing. Since the arc surface of the fan-shaped frame 322 is in contact with the arc plate 320, when the fan-shaped frame 322 swings, it can be limited by the arc plate 320, so that the snap-fit ​​block 305 can move back and forth more stably, increasing the stability of the welding wire harness 5 feeding.

[0038] During operation, after the welding wire harness 5 is placed inside the wire harness clamping mechanism 4, the motor 309 can be started. During the start-up process, the meshing transmission between the bevel gear 2 310 and the bevel gear 1 308 drives the rotating shaft 1 307 to rotate inside the mounting block 1 306, thereby driving the swing arm 1 311 to perform circular motion. This, in turn, drives the swing arm 2 316 to swing under the action of the connecting arm 1 317, causing the actuating plate 323 to swing. When the actuating post 324 installed inside the actuating plate 323 enters the limiting groove inside the actuating rod 321, it drives the actuating rod 321 to swing, causing the rotating shaft 315 to rotate. This, in turn, drives the locking block 305 to move back and forth between the two baffles 304 under the action of the swing rod 318 and the connecting rod 319. After the welding harness 5 is placed, the starting of the motor 309 drives the clamping block 305 to move between the two baffles 304 toward the welding head 205. This allows the clamping block 305 to position the wire harness clamping mechanism 4 directly below the welding head 205, enabling welding of the welding harness 5 through the welding head 205. After welding is completed, the motor 309 is rotated again, causing the clamping block 305 to move the wire harness clamping mechanism 4 away from below the welding head 205. At this point, the welded welding harness 5 can be removed, and the next welding harness 5 can be placed. This achieves the goal of keeping the welding harness 5 away from below the welding head 205 during the removal and placement process, thereby improving safety during the removal and placement of the welding harness 5. Furthermore, it achieves the purpose of automatic feeding and welding of the welding harness 5, completing the welding and loading operation of the welding harness 5.

[0039] The wire harness clamping mechanism 4 includes a connecting frame 401, a top plate 402 fixedly mounted on the top surface of the connecting frame 401, a placement block 403 mounted on the top surface of the top plate 402, a snap-fit ​​groove 325 formed on the inner side of the baffle 304, one end of the connecting frame 401 snapping into the inside of the snap-fit ​​groove 325 and fixedly connected to one side surface of the snap-fit ​​block 305, a positioning groove 408 formed inside the placement block 403, a guide post 409 installed inside the positioning groove 408, the welding wire harness 5 snapping into the inside of the positioning groove 408, and an external bracket 404 fixedly mounted on the outer side of the baffle 304. A wedge block 405 is provided below the bracket 404. The top surface of the placement block 403 is inclined. A fixed sleeve 406 is fixedly connected to the top surface of the wedge block 405. A movable sleeve 407 is movably sleeved inside the fixed sleeve 406. A spring is fixedly connected between the bottom surface of the movable sleeve 407 and the inner bottom surface of the fixed sleeve 406. The top surface of the movable sleeve 407 is connected to the inner bottom surface of the outer bracket 404. A welding table 410 is connected to one side surface of the placement block 403. An electromagnet 411 is installed on the top surface of the welding table 410. A limit strip is fixedly installed on the top surface of the welding table 410.

[0040] During operation, in the welding process, the welding wire harness 5 is first placed inside the positioning groove 408. The guide post 409 allows the two ends of the welding wire harness 5 to be separated. Then, the placement block 403 moves synchronously with the snap-fit ​​block 305 during its movement. As the snap-fit ​​block 305 moves towards the welding head 205, the placement block 403 gradually approaches the wedge block 405. Because one side of the placement block 403 is sloped, when the slope of the placement block 403 meets the wedge surface of the wedge block 405... After contact, the wedge block 405 moves upward, which in turn causes the movable sleeve 407 to gradually retract into the fixed sleeve 406. Under the action of the second spring, the wedge surface of the wedge block 405 can be tightly fitted with the inclined surface of the placement block 403, thereby stably pressing the welding wire harness 5 against the inside of the positioning groove 408, realizing the automatic clamping of the welding wire harness 5. This achieves the purpose of automatically clamping the welding wire harness 5 during the welding process, making the welding wire harness 5 more stable in the subsequent welding process.

[0041] The terminal welding feeding mechanism 8 includes a terminal storage box 801, which is fixedly installed on the bottom surface of the cross frame 202. Multiple welding terminals 9 are placed inside the terminal storage box 801. A discharge chute 802 is provided at the bottom of the terminal storage box 801. A retaining block 803 is movably engaged inside the terminal storage box 801. A spring 804 is fixedly connected between the retaining block 803 and the inner top surface of the terminal storage box 801. An installation groove 805 is provided inside the welding table 410. An installation shaft 806 is rotatably mounted inside the installation groove 805. An installation sleeve 807 is fixedly sleeved on the outer surface of the installation shaft 806. A folding plate 808 is installed on the side, and a torsion spring 809 is provided on the outer side of the mounting shaft 806. A mounting bracket 810 is fixedly installed on the top surface of the connecting bracket 303, and a toothed plate 811 is fixedly installed on the top of the mounting bracket 810. A through groove 812 is opened on the top surface of the welding table 410, and a through hole 813 is opened inside the through groove 812. A plug shaft 814 is rotatably installed inside the through hole 813. A guide wheel is fixedly installed on the outer surface of the plug shaft 814 located inside the through groove 812, and a belt 816 is sleeved on the outer surface of the guide wheel. Both ends of one of the plug shafts 814 are fixedly installed with meshing gears 815, and the meshing gears 815 mesh with the toothed plate 811.

[0042] During operation, the welding table 410 moves synchronously with the movement of the placement block 403. When the welding end of the welding harness 5 located at the top of the welding table 410 reaches directly below the welding head 205, the folding plate 808 at one end of the welding table 410 is positioned behind the terminal storage box 801. After the welding harness 5 located below the welding head 205 is welded to the welding terminal 9, the welding table 410 moves away from the welding head 205 under the action of the harness feeding mechanism 3. At this time, under the action of the folding plate 808, the welding terminal 9 stacked inside the terminal storage box 801 can be moved to the top surface of the welding table 410 and located inside the two guide frames 412. Then, during the retraction of the welding table 410, the meshing gear 815 rotates under the action of the toothed plate 811, thereby driving the insertion shaft 814 to rotate, which in turn drives the guide wheel to rotate, causing the belt 8 to rotate. 16 moves, thereby moving the folding plate 808 to the inside of the through slot 812 and transporting the welding terminal 9 towards the electromagnet 411 until one side surface of the welding terminal 9 contacts one side surface of the electromagnet 411, or when the welding terminal 9 is close to the electromagnet 411, the electromagnet 411 can attract the welding terminal 9, thus fixing the welding terminal 9. That is, when the welding table 410 moves towards the welding head 205, the welding terminal 9 is in an attracted and fixed state and will not be driven by the belt 816, thus achieving the purpose of automatic feeding and fixing of the welding terminal 9. Furthermore, through the provided torsion spring 809, when the back of the folding plate 808 contacts the welding terminal 9 inside the terminal storage box 801, it can retract into the mounting slot 805, and then be fixed when the welding table 410 retracts, moving the welding terminal 9 to the top surface of the welding table 410.

[0043] Specifically, the working process or principle of this automotive wiring harness terminal welding equipment is as follows: First, the wiring harness 5 to be welded is placed inside the wiring harness clamping mechanism 4. Then, multiple welding terminals 9 are neatly stacked inside the terminal welding feeding mechanism 8. Next, the wiring harness feeding mechanism 3 drives the wiring harness clamping mechanism 4, which holds the welding harness 5, to move directly below the welding head 205. At this point, the cylinder 204 drives the welding head 205 to weld the welding harness 5 and the welding terminals 9. The motor 309 is started, and during this start-up process, the meshing transmission between the bevel gear 210 and the bevel gear 308 drives the rotating shaft 307 to rotate on the mounting block 306. The internal rotation drives the swing arm 311 to perform circular motion, which in turn drives the swing arm 316 to swing under the action of the connecting arm 317, causing the actuating plate 323 to swing. When the actuating post 324 installed inside the actuating plate 323 enters the limiting groove opened inside the actuating rod 321, it drives the actuating rod 321 to swing, causing the rotating shaft 315 to rotate. This allows the locking block 305 to move back and forth between the two baffles 304 under the action of the swing rod 318 and the connecting rod 319. That is, after the welding wire harness 5 is placed, the start of the motor 309 can drive the locking block 305 to move between the two baffles 304 towards the welding head 205. The movement of the snap-fit ​​block 305 causes the wire harness clamping mechanism 4 to be positioned directly below the welding head 205, enabling welding of the wire harness 5 via the welding head 205. As the snap-fit ​​block 305 moves toward the welding head 205, the placement block 403 gradually approaches the wedge block 405. Since one side of the placement block 403 is inclined, when the inclined surface of the placement block 403 contacts the wedge surface of the wedge block 405, the wedge block 405 moves upward, causing the movable sleeve 407 to gradually retract into the fixed sleeve 406. Under the action of the spring, the wedge surface of the wedge block 405 and the inclined surface of the placement block 403 are tightly fitted, thus stabilizing the welding of the wire harness 5. Pressed against the inside of the positioning groove 408, the folding plate 808, under its action, can move the welding terminal 9 stored inside the terminal storage box 801 to the top surface of the welding table 410 and place it inside the two guide frames 412. Then, during the retraction of the welding table 410, the meshing gear 815 can rotate under the action of the toothed plate 811, thereby driving the plug shaft 814 to rotate, which in turn drives the guide wheel to rotate, causing the belt 816 to move. This moves the welding terminal 9, which has been moved by the folding plate 808 to the inside of the through groove 812, towards the electromagnet 411, until one side surface of the welding terminal 9 contacts one side surface of the electromagnet 411, or when the distance between the welding terminal 9 and the electromagnet 411 is close.Electromagnet 411 can attract and fix welding terminal 9, thus fixing it in place. Specifically, when welding table 410 moves towards welding head 205, welding terminal 9 remains attracted and fixed, and is not moved by belt 816, thereby achieving automatic feeding of welding terminal 9.

[0044] It should be noted that the motor 309 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
