DETAILED DESCRIPTION

[0050] Example One:

[0051] Terminology:

[0052] In manufacturing, high flexibility generally refers to the flexibility and adaptability of products or production processes.

[0053] In one exemplary embodiment of the present application, as shown in FIG. Figure 1 A die casting production line is provided.

[0054] In the existing die casting manufacturing process, die casting, deburring and machining are usually designed as four independent production lines to overcome the error between die casting OEE and machining OEE. Based on this, the present embodiment provides a die casting production line, which calculates the production cycle of the die casting unit, the go-away-from-pouring-row unit, the deburring unit and the machining unit, and designs the production line equipment and fixtures with high flexibility and cost reduction based on the purpose of zero interference between processes, high efficiency of product variety switching, production line integration cost reduction and few people.

[0055] Next, the above-mentioned die casting production line will be described in detail in conjunction with the accompanying drawings.

[0056] The die casting production line of the present embodiment includes a die casting unit, a go-away-from-pouring-row unit, a deburring unit and a machining unit, integrates the four units on the same continuous production line, and provides a plurality of conveyors. The conveyors serve as the dividing equipment for the above-mentioned four parts, so that the blanks can be fed in and out, and when any unit fails, the other units can operate independently; The production from continuous die casting to deburring to machining can be realized. And by using a high flexibility scheme for spraying, picking, going away from the pouring row, deburring and machining, the product variety switching scheme of the production line is simplified, and the variety time of fixtures and tooling is effectively reduced.

[0057] Specifically, as shown in FIG.Figure 2 As shown, the die-casting unit includes a die-casting machine 3, a molten metal feeding device 2, an automatic spraying device 4, a cooling device 10, a first conveying robot 9, a first conveyor 11, etc. The die-casting machine 3 has a die-casting mold 22 between its head and tail. The automatic spraying device 4 is located on one side of the die-casting mold 22 and can reach down to the die-casting mold 22 to complete the spraying of the release agent. The first conveyor 11 is used for the products of the die-casting unit to be unloaded and the products of the de-gating unit to be loaded.

[0058] The first conveying robot 9 is used to remove the product from the die-casting mold 22 and place it in the cooling device 10 for cooling. The cooled product is then placed in the de-gating unit. The first conveying robot 9 facilitates the transfer of the product between the die-casting unit and the de-gating unit. A first product gripper 35 is mounted at the end of the first conveying robot 9. Figure 12 As shown, the first product fixture 35 adopts a universal structure, which can realize the picking action of different products with material handle diameters ranging from D1 to D2, and realize the common use of all products when picking up parts on the production line.

This enables the spraying coverage of all die-casting molds 22 on the production line, thereby achieving high flexibility and versatility in spraying.

[0060] The die-casting unit also includes an integrity testing device 7 and a scrap cart 8. Before the first conveying robot 9 places the product into the cooling device 10, it must undergo integrity testing by the integrity testing device 7. Only products that meet the requirements will enter the cooling process. In the die-casting unit, hot molded parts or abnormal products at the start of the equipment can be directly discarded and put into the scrap cart 8.

[0061] like Figure 4 As shown, the integrity detection device 7 includes multiple sensors 23 arranged in a matrix. Based on feature recognition of different products and program control, it achieves detection at designated locations, thereby realizing universality of detection and high flexibility in integrity detection.

According to the calculation of the product beat and the cutting position, two laser cutting robots 25 are used to cut the runner and the vent of the blank at the same time, so that the beat balance of the production line can be realized. It can be understood that in other embodiments, the number of laser cutting robots 25 can be adjusted adaptively according to actual needs.

[0067] As shown in Figure 8 The deburring unit includes a deburring station 16, a third conveyor 17, and a third conveying robot 18. The deburring station 16 is used for deburring processing of the product. The end of the third conveying robot 18 is provided with a third product clamp 37, which is used to convey the deburred blank from the third product clamp 37 to the processing unit, or when the subsequent process is abnormal, the third product clamp 37 can be offline through the third conveyor 17.
