[0019] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Example:

[0021] like Figure 1 , Figure 2 and Figure 3As shown: an automobile wiring harness production line is provided with an annular assembly line support frame 1, an annular drive chain structure 2 is installed on the upper part of the annular assembly line support frame 1, a driving mechanism 3 is arranged on one end of the annular assembly line support frame 1, a driving sprocket structure 31 is installed at the output end of the driving mechanism 3, and a driven sprocket structure 4 is installed at the other end of the annular assembly line support frame 1. The annular drive chain structure 2 is sleeved between the driving sprocket structure 31 and the driven sprocket structure 4, and a reversible tooling plate frame mechanism 5 is evenly connected to the annular drive chain structure 2. The annular drive chain structure 2 is used to drive the reversible tooling plate frame mechanism 5 to move on the annular assembly line support frame 1. The driving mechanism 3 is composed of a stepper motor or a variable frequency motor connected to a reduction mechanism. The stepper motor and the variable frequency motor are easy to control the moving speed, so that the assembly line speed can adapt to the production of workers with different proficiency, so that the production efficiency is higher. Generally, a stepper motor is used, which has lower cost. Permanent magnet synchronous motors and induction motors can also be used, but the cost is too high.

[0022] An upper annular guide rail 11 is also provided on the upper part of the annular assembly line support frame 1, and a lower annular guide rail 12 is provided on the lower part of the annular assembly line support frame 1. The upper and lower ends of the flip tooling plate frame mechanism 5 are respectively matched with the upper annular guide rail 11 and the lower annular guide rail 12. The annular drive chain structure 2 is arranged above the upper annular guide rail 11. A material rack and a lamp tube ceiling are also provided on the top of the annular assembly line support frame 1. The material rack and the lamp tube ceiling are sequentially arranged above the annular drive chain structure 2.

[0023] The above-mentioned reversible tooling plate frame mechanism 5 includes an assembly line tooling bracket 51 and a tooling plate frame 52. The two ends of the tooling plate frame 52 are rotatably mounted on the assembly line tooling bracket 51. A rotating shaft structure is arranged in the middle of the tooling plate frame 52. A rotating clamping seat is arranged in the middle of the assembly line tooling bracket 51. The rotating shaft structure is rotatably mounted on the rotating clamping seat. The upper part of the rotating clamping seat has a U-shaped bayonet. When the tooling plate frame 52 needs to be disassembled, it is only necessary to remove the rotating shaft structure from the U-shaped bayonet, which is convenient for removing from the assembly line tooling bracket. The entire tooling plate rack 52 is disassembled from the tooling plate rack 51 to complete the quick replacement. The disassembled tooling plate rack 52 is transported to the tooling manufacturing workshop to directly replace the tooling plates on each surface, and another tooling plate rack 52 is installed on the assembly line tooling bracket 51. Therefore, after a certain type of wiring harness is eliminated and the tooling plate is replaced again, the production efficiency of the wiring harness in the production workshop will not be affected; the U-shaped bayonet has arc chamfered portions on both sides, which is convenient for the installation of the shaft structure of the tooling plate rack 52 without manual alignment, and the installation stability is also high.

[0024] The tooling plate rack 52 has at least two tooling plate mounting surfaces, and a locking mechanism is provided on the assembly line tooling bracket 51 for locking the tooling plate rack 52 .

[0025] The locking mechanism is a transverse mounting support rod provided in the middle of the assembly line tooling bracket 51, and a locking control seat is installed on the transverse mounting support rod. The locking control seat has a flat cylindrical seat, and the lower part of the arc outer surface of the cylindrical seat is fixedly arranged on the transverse mounting support rod. A control bevel groove is opened along the upper part of the arc outer surface of the cylindrical seat, and a locking rod movable hole is also provided at the center of the end face of the cylindrical seat. The locking rod movable hole is connected with the control bevel groove, and a locking rod is movably installed in the locking rod movable hole. A control rod is fixedly connected to the locking rod, and the control rod passes through and is restricted in the control bevel groove. As the control rod is in different clamping positions of the control bevel groove, the locking rod telescopes and moves in the locking rod movable hole. The locking rod and the control rod are overall in a "T" shape or an "L" shape. The locking rod movable hole can be a through hole or a hole groove with a larger movable space.

[0026] Three locking holes, or other numbers of locking holes, are provided at the end of the tooling plate frame 52. The three locking holes are arranged in an arc shape, and the distances between the three locking holes and the rotating shaft structure are the same. The locking rod cooperates with the locking hole structure, that is, the locking rod is inserted into the locking hole to cooperate, thereby completing the locking work of the tooling plate frame 52. Multiple locking holes are used to adjust different working inclination angles. The locking mechanism enables the tooling plate to flip and switch quickly, thereby improving production efficiency and being able to keep the panel sufficiently stable during the production process.

[0027] An upper guide wheel structure 6, a roller mechanism 7 and a lower guide wheel structure 8 are respectively installed on the assembly line tooling bracket 51. The upper guide wheel structure 6 and the lower guide wheel structure 8 are respectively installed horizontally at the upper and lower parts of the assembly line tooling bracket 51. The upper guide wheel structure 6 and the lower guide wheel structure 8 are respectively matched with the upper annular guide rail 11 and the lower annular guide rail 12. The roller mechanism 7 is installed at the bottom of the assembly line tooling bracket 51, and the roller mechanism 7 is used for rolling on the ground.

[0028] The lower guide wheel structure 8 is provided with two groups of guide wheels, each group of guide wheels is composed of two guide wheels, and the two guide rails are respectively rollingly fitted on both sides of the lower annular guide rail 12, and the ring diameter of the lower annular guide rail 12 is larger than the upper annular guide rail 11. The upper guide wheel structure 6 is also provided with two groups of guide wheels, but each group of guide wheels is composed of only one guide wheel, because the upper guide wheel structure 6 is only used for stabilization, and will fall off from the upper annular guide rail 11 in sequence at the curved rail.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention shall be defined by the appended claims.
