[0020] Figure 3A , Figure 3B andFigure 3C is a process schematic diagram of using Figure 1 the pallet mechanism shown in the figure. Specific embodiments

[0021] Figure 1 is a perspective view of a pallet mechanism according to an exemplary embodiment of the present invention. Figure 2A is Figure 1 a perspective view of the pallet mechanism shown in a disassembled state. Figure 2B Figure 1 a side view of the pallet mechanism shown in a disassembled state. Figure 2C is Figure 1 a top view of the pallet mechanism shown in a disassembled state.

[0022] As Figures 1 to 2C shown, the pallet mechanism 100 for manufacturing an assembly according to the present invention mainly includes a pallet base 1, a pallet body 2, and a plurality of molds 31, 32, 33, 34. The pallet base 1 can be conveyed by a conveyor belt (not shown) on a production line so as to move and stop. The pallet body 2 is mounted on the pallet base 1. The plurality of molds 31, 32, 33, 34 are mounted on the pallet body 2 for respectively supporting components 91, 92, 93, 94 (to be described in detail later with reference to Figures 3A to 3C ) of an assembly to be assembled (such as a clock spring).

[0023] The pallet mechanism 100 further includes a pallet holder 4. One end of the pallet holder 4 is fixed to the pallet body 2, and the other end of the pallet holder 4 is adapted to be blocked and fixed by a positioning device (not shown) on the production line, thereby blocking and fixing the pallet mechanism 100.

[0024] In the pallet mechanism 100, the pallet body 2 is detachably mounted on the pallet base 1 to allow for quick replacement of the pallet body 2 and the plurality of molds 31, 32, 33, 34. Further, the plurality of molds 31, 32, 33, 34 are detachably mounted on the pallet body 2 to allow for quick replacement of at least one of the plurality of molds 31, 32, 33, 34.

[0025] Specifically, the pallet body 2 is fastened to the pallet base 1 by at least one (two in this exemplary embodiment) locking screws 51, 52 via through holes 71 provided on the pallet body 2. Further, the locking screws 51, 52 have nuts adapted to be manually screwed so as to be manually tightened and loosened. In this way, the user of the pallet mechanism 100 can conveniently replace the pallet body 2 without the aid of other auxiliary tools, thereby achieving the purpose of quick changeover.

[0026] To make the tray base 1 and the tray body 2 fit together more accurately and firmly, a groove 11 can be provided on the tray base 1, and the tray body 2 is embedded in the groove 11. Further, a plurality of (three in this exemplary embodiment) positioning pins 61, 62, 63 are fixed on the tray base 1, and a plurality of pin holes 81, 82, 83 are correspondingly formed on the tray body 2. Each positioning pin 61, 62, 63 is inserted into the corresponding pin hole 81, 82, 83 to accurately and firmly position the tray body 2 relative to the tray base 1.

[0027] The assembly to be assembled described in this exemplary embodiment can be a rotary clock spring for a vehicle. Next, the assembly process of the clock spring and the usage mode of the tray mechanism 100 will be described with reference to Figures 3A to 3C to describe the assembly process of the clock spring and the usage mode of the tray mechanism 100.

[0028] As Figure 3A 、 Figure 3B and Figure 3C shown, the components of the assembly mainly include a base 91, a protective cover 92, and a front cover 93. Correspondingly, the plurality of molds installed on the tray body 2 mainly include a first mold 31, a second mold 32, a third mold 33, and a fourth mold 34. The first mold 31 is adapted to support the base 91. The second mold 32 is adapted to support the protective cover 92. The third mold 33 is adapted to support the front cover 93. The fourth mold 34 also serves as a tape winding device while being used as a mold, allowing the respective components 91, 92, 93 of the assembly to complete the general assembly and tape winding processes on the fourth mold 34.

[0029] Specifically, as Figure 3A shown, the base 91 is supported on the first mold 31 and the assembly of related parts is completed, the protective cover 92 is supported on the second mold 32 and the assembly of related parts is completed, the front cover 93 is supported on the third mold 33 and the assembly of related parts is completed, and the belt rotating shaft 94 is supported on the fourth mold (i.e., the tape winding device) 34 and the assembly of related parts is completed.

[0030] Then, as Figure 3B and Figure 3C shown, the base 91 supported on the first mold 31, the protective cover 92 supported on the second mold 32, and the front cover 93 supported on the third mold 33 are sequentially / gradually assembled onto the fourth mold 34, thereby completing the general assembly process of the clock spring.

[0031] Then, the tape winding device 34 is started to wind the spring tape into the cavity enclosed by the base 91 of the clock spring, thereby completing the tape winding process of the clock spring. It can be seen that since the tray mechanism 100 comes with the tape winding device 34, the assembly efficiency of the clock spring is improved, and there is stronger flexibility and adaptability in the production line of the clock spring.

[0032] It should be noted that, in addition to the stopping and fixing functions mentioned above, the tray holder 4 can also expand the following functions: A spring band arranging tooling (not shown) is additionally installed on the tray holder 4, and the spring band passes through the spring arranging tooling, so as to guide the spring band, thereby solving the problem of the spring band being misaligned during the winding process.

[0033] Although the tray mechanism 100 of the present invention has been described above by taking the clock spring as an example of the assembly, it should be understood that the assembly is not limited to the clock spring, and can also be other assemblies, as long as it is suitable for applying the tray mechanism of the present invention that can be quickly changed in type.

[0034] Although the technical purpose, technical solution and technical effect of the present invention have been described in detail above with reference to specific embodiments, it should be understood that the above embodiments are only exemplary and not restrictive. Any modification, equivalent replacement, and improvement made by those skilled in the art within the spirit and principle of the present invention are included in the protection scope of the present invention.
