Description

Technical Field

[0001] This utility model relates to an automatic wire harness assembly device, specifically to an automatic stator wire harness assembly machine. Background Technology

[0002] The stator of the magneto requires the assembly of wire harnesses. These harnesses consist of multiple strands of copper wire, each soldered to a lead wire on the magneto. Each wire requires two manual steps: first, aligning the end of the wire harness with the soldering point of the lead wire; then, using clamps to hold and press the wire; finally, using a soldering gun to secure the lead wire and harness. This current method of single-wire, single-soldering cannot simultaneously solder multiple wire harnesses, resulting in low efficiency, cumbersome operation, slow speed, and inconsistent soldering quality. Utility Model Content

[0003] The present invention aims to provide an automatic stator wire harness assembly machine that can automatically press and weld stator leads and wire harnesses.

[0004] The stator wire harness automatic assembly machine in this solution includes a machine base frame with a table panel on it. The table panel has a tooling assembly, a pressing assembly, and a soldering assembly. The tooling assembly is slidably mounted on one end of the table panel, and the pressing assembly and the soldering assembly are sequentially arranged along the sliding path of the tooling assembly. The tooling assembly includes a tooling base plate, on which a stator fixing frame and a wire harness fixing frame are correspondingly mounted. The wire harness fixing frame includes a wire harness frame base, a wire harness fixing device, and a wire harness positioning device. The wire harness frame base is fixedly mounted on the tooling base plate, and the wire harness fixing device is located on top of the wire harness frame base. The wire harness fixing device has multiple wire harness fixing slots, and each wire harness fixing slot has a cover plate. The wire harness positioning device has a slidably mounted positioning block with multiple positioning slots. The positioning block can slide to the front end of the wire harness fixing slot, so that the positioning slot corresponds to the wire harness fixing slot.

[0005] The operator places the stator onto the stator mounting bracket, then places each strand of the multi-strand wire harness into its corresponding wire harness mounting slot, leaving an appropriate length of wire harness with its connector exposed outside the slot. The cover plate is then flipped to fix the wire harness position. The positioning block slides upward, placing the wire harness welding connector into the positioning slot, and connecting the stator lead wire and the wire harness welding connector within the positioning slot. The tooling assembly slides to the pressing assembly for pressing connection, and then continues to slide to the soldering assembly for soldering.

[0006] Furthermore, the wire harness positioning device includes a positioning slide, a connecting arm, and the positioning block. The positioning slide is slidably connected to the wire harness frame base, and both ends of the connecting arm are fixedly connected to the positioning slide and the positioning block, respectively.

[0007] Furthermore, the stator fixing frame includes a stator support and a stator positioning plate. The bottom of the stator support is vertically fixed to the tooling base plate, and the stator positioning plate is fixed to the top of the stator support. A stator positioning post is provided at the center of the stator positioning plate, and a positioning pin is provided on the stator positioning plate on one side of the stator positioning post.

[0008] Furthermore, the positioning block is provided with a pressure plate, which is rotatably pressed onto multiple positioning slots. The pressure plate pre-compresses the wire harness and stator leads that need to be connected.

[0009] Furthermore, a stop ring is provided on the outer periphery of the stator positioning disk, and the stop ring is fixedly mounted on the stator support. The stop ring is used to limit the movement of the stator.

[0010] Furthermore, one end of the pressure plate is hinged to one end of the positioning block, the free end of the pressure plate is locked by a spring clip, and the spring clip is hinged to the other end of the positioning block.

[0011] Furthermore, the tabletop is provided with a horizontal sliding guide rail, and the lower surface of the tooling base plate slides in cooperation with the horizontal sliding guide rail.

[0012] Furthermore, the base of the wire harness frame is provided with a vertical sliding guide rail, and the seat of the positioning slide block is slidably engaged with the vertical sliding guide rail; the seat of the positioning slide block is also provided with a lifting handle and a stop screw, and the stop screw is provided with a rotating handle.

[0013] Furthermore, a buffer spring is provided between the positioning slide and the wire harness base.

[0014] Furthermore, the opening of the positioning groove near one end of the stator fixing bracket is a flared opening. The flared opening facilitates the insertion of wire ends.

[0015] The advantages of this invention are: the automatic stator harness assembly machine designed with this solution only requires one manual operation for docking, after which it can automatically complete the pressing and welding. Thus, the entire assembly process of wire pressing and welding is automated, resulting in fast production speed, high welding efficiency, and stable and reliable welding quality.

That is, the workpiece to be assembled is installed on the tooling assembly 500, the tooling assembly 500 slides to the pressing assembly 300 for pressing by driving force, and then slides to the soldering assembly 400 for soldering.

[0026] The tooling assembly 500 includes a tooling base plate 1, and a horizontal sliding guide rail 2 is provided on the table panel 200. The lower surface of the tooling base plate 1 is slidably engaged with the horizontal sliding guide rail 2. The tooling base plate 1 is connected to a driving device, which can be a motor. The tooling base plate 1 is provided with a stator fixing frame and a wire harness fixing frame.

A cover plate 7 is provided on the wire harness fixing slot 6, and one end of the cover plate 7 is hinged and rotatable.

[0027] The wire harness frame base 3 is equipped with a vertical sliding guide rail 19, and the seat of the positioning slide 5-1 is slidably engaged with the vertical sliding guide rail 19. The seat of the positioning slide 5-1 is also equipped with a lifting handle 8 and a stop screw, and the stop screw is equipped with a rotating handle 9. A buffer spring 10 is also provided between the positioning slide 5-1 and the wire harness frame base 3.

[0028] The wire harness positioning device 5 includes a positioning slide 5-1, a connecting arm 5-2, and a positioning block 5-3.

The positioning block 5-3 is provided with a plurality of positioning grooves 11. In this embodiment, the number of positioning grooves 11 is three.

[0029] In this embodiment, there are two connecting arms 5-2. One end of each connecting arm 5-2 is bolted to both ends of the positioning slide 5-1, and a positioning block 5-3 is bolted between the two connecting arms 5-2 at the other end. The positioning block 5-3 can slide to the front end of the wire harness fixing groove 6, so that the positioning groove 11 corresponds to the wire harness fixing groove 6. A pressure plate 12 is hinged to one end of the positioning block 5-3. One end of the pressure plate 12 can rotate and press against the positioning groove 11. The other free end of the pressure plate 12 is locked by a spring clip 13, which is hinged to the other end of the positioning block 5-3.

[0030] The stator mounting bracket includes a stator support 14 and a stator positioning plate 15. The bottom of the stator support 14 is vertically fixed to the base plate 1 of the fixture.

[0031] As a further improvement of this embodiment, the groove opening of the positioning groove 11 near the stator fixing frame is a flared opening, that is, the opening at the end of the positioning groove 11 is larger than the inner diameter of the groove.

[0032] The operator places the stator 600 onto the stator mounting bracket according to the position of the positioning pin 17, and then places each of the three wire harnesses 700 into the corresponding wire harness fixing slot 6, leaving an appropriate length of wire harness and exposing its connector outside the wire harness fixing slot 6. The cover plate 7 is flipped to fix the position of the wire harness. The positioning block 5-3 moves upward, so that the welding connector of the wire harness is placed in the positioning slot 11, and the lead wire on the stator and the welding connector of the wire harness are connected in the positioning slot 11. The pressure plate 12 is flipped to perform pre-pressing and fixing. The pressure plate 12 is opened, and the drive device is started so that the tooling assembly 500 slides along the horizontal sliding guide rail 2 to the pressing assembly 300 for pressing and connection, and then continues to slide to the soldering assembly 400 for soldering.

[0033] The stator harness automatic assembly machine designed using this solution requires only one manual pre-pressing and docking operation before automatically completing the pressing and welding.
