[0019] Please refer to Figures 1-17 A decorative strip processing production line includes a loading device 1, a first conveying device 2, a milling device 3, a burr removal device 4, a coding device 5, a punching device 6, a blanking device 7 and a polishing device 8; the milling device 3, the burr removal device 4, the coding device 5 and the loading device 1 are arranged in sequence around the first conveying device 2, and form a first working area 101; the punching device 6 and the polishing device 8 are located in the second working area 102, and the blanking device 7 is located in the third working area 103, and the first working area 101 and the third working area 103 are respectively located on opposite sides of the second working area 102 and are respectively connected to the second working area 102; the areas where the milling device 3, the burr removal device 4, the coding device 5 and the loading device 1 are located are respectively connected to the areas where the first conveying device 2 is located, so that the first conveying device 2 drives the decorative strip 20 to be processed to move to different areas for processing. Preferably, two punching devices 6 are provided in the second working area 102, and the two punching devices 6 are symmetrically arranged.

[0020] It is understood that in the first operation area 101, by surrounding the first handling device 2 with a loading device 1, a milling device 3, a burr removal device 4, and a coding device 5, the first handling device 2 is capable of transferring the decorative strips 20 between various processes, thereby achieving automated production. Furthermore, a stamping device 6 and a polishing device 8 are provided in the second operation area 102, and an unloading device 7 is provided in the third operation area 103, thereby achieving automatic stamping, grinding, polishing, and unloading of the decorative strips 20. In the present invention, the entire decorative strip processing production line has a high degree of integration and automation, and can completely replace manual labor. Compared with traditional production lines, the first handling device 2 replaces multiple transmission devices in traditional production lines, resulting in a compact structure and a small footprint.

[0021] In some embodiments, the first handling device 2 includes a first manipulator 21, a first quick-change plate 22, and a first clamp 23. The first clamp 23 is detachably connected to the movable end of the first manipulator 21 via the first quick-change plate 22. The first manipulator 21 is used to drive the first clamp 23 to clamp the decorative strips 20 located in the loading device 1 and transfer the decorative strips 20 to the milling device 3, the burr removal device 4, and the coding device 5 for corresponding processing. Preferably, the first clamp 23 can simultaneously clamp four decorative strips 20. Accordingly, in the first working area 101, at least two sets of first mold storage racks 24 are provided for accommodating different clamps, and the at least two sets of first mold storage racks 24 are arranged opposite each other.

[0022] In some embodiments, the stamping device 6 includes a stamping mechanism 61 and a second transport device 62; the stamping mechanism 61 and the second transport device 62 are arranged along a straight line of the second working area 102, and the second transport device 62 is disposed adjacent to the first working area 101 and the third working area 103, so that the second transport device 62 can move the decorative strips 20 in the first working area 101 into the stamping mechanism 61 and move the decorative strips 20 in the stamping mechanism 61 into the third working area 103. In the second working area 102, a set of second mold storage frames 63 is disposed between each stamping mechanism 61 and the second transport device 62. Among them, the second handling device 62 includes a second manipulator 621, a second quick-change plate 622, and a second clamp 623; the second clamp 623 is detachably connected to the movable end of the second manipulator 621 through the second quick-change plate 622. The second manipulator 621 is used to drive the second clamp 623 to transfer the coded decorative strip 20 to the stamping mechanism 61 for stamping, and transfer the stamped decorative strip 20 to the polishing device 8 for polishing, and then transfer it to the unloading device 7 to achieve automatic stamping and automatic unloading. Through the cooperation of the second manipulator 621 and the second clamp 623, two material transfers can be achieved, replacing the setting of the conveyor mechanism and reducing the occupied space. In addition, the setting of the second quick-change plate 622 can realize the rapid connection and rapid disassembly of the second clamp 623 and the second manipulator 621, making it easier for the second manipulator 621 to replace the second clamp 623.

[0023] In some embodiments, the stamping mechanism 61 includes a pressure drive assembly 611, a stamping die 612 and a stamping support seat 613; the stamping die 612 includes an upper die 614 arranged relatively to each other and a lower die 615 for fixing the decorative strip 20 to be stamped; a reset member 616 is provided between the upper die 616 and the lower die, and optionally, at least two reset members 616 are provided in the length direction of the upper die 614; the upper die 614 is transmission-connected to the movable end of the pressure drive assembly 611, and the lower die 615 is detachably connected to the stamping support seat 613, and the pressure drive assembly 611 is used to drive the upper die 614 to gradually approach or gradually move away from the lower die 615.

Preferably, the pressure drive assembly 611 includes a cylinder 6111 and a connecting head 6112, and the connecting head 6112 is arranged at the movable end of the cylinder 6111. Correspondingly, the upper mold 614 has two symmetrically arranged stamping blocks 6141 on the side away from the lower mold 615. The two stamping blocks 6141 form a space for sliding connection with the connecting head 6112, so that the upper mold 614 is slidably connected to the connecting head 6112. Specifically, during the stamping process, the oil cylinder 6111 drives the connector 6112 downward, and the connector 6112 applies pressure to the side of the upper die 614 away from the lower die 615. At this time, the connector 6112 is separated from the punching block 6141. When the oil cylinder 6111 and the upper die 614 are reset, the reset member 616 between the upper die 614 and the lower die 615 pushes the upper die 614 to reset. When the reset member 616 fails, the oil cylinder 6111 drives the connector 6112 upward, and the connector 6112 presses against the two punching blocks 6141, thereby driving the upper die 614 to reset. At this time, the punching block 6141 plays an error-proofing role. By setting the stamping die 612, the decorative strip 20 can be stamped into the desired shape. Furthermore, a pressure detection interface is provided in the oil cylinder 6111, through which the pressure is monitored, and the faults and working status of the oil cylinder 6111 are quickly diagnosed, so that the oil cylinder 6111 can be promptly processed. A corresponding blow valve is also provided in the lower die 615, and the blowing time of the blow valve is controlled by a solenoid valve. The blowing direction of the blow valve can be adjusted to remove the waste and impurities remaining on the lower die 615. At the same time, a lubrication component is also provided in the stamping die 612 to lubricate the stamping die 612 and the decorative strip 20. Preferably, the reset member 616 is a nitrogen spring.

[0024] In some embodiments, the stamping mechanism 61 further includes a die shifting assembly 64; the die shifting assembly 64 is connected to the stamping support seat 613. Preferably, the upper die 614 is slidably connected to the connector 6112, and the die shifting assembly 64 is located in the relative sliding direction between the upper die 614 and the connector 6112, for the purpose of enabling a forklift to disassemble the stamping die 612 as a whole through the die shifting assembly 64 and replace other stamping dies 612 to meet the stamping requirements of different models of products. Specifically, the die shifting assembly 64 includes a die lifter 641 arranged between the lower die 615 and the stamping support seat 613 and a die shifting arm 642 arranged on one side of the width direction of the lower die 615, wherein the die shifting arm 642 is used to cooperate with an external forklift to replace the stamping die 612 as a whole.
