DETAILED DESCRIPTION

[0032] like Figure 11 As shown, the finished product of the present invention is a semicircular structure product. Before processing, the product is a disc with an edge having a height of several centimeters. After processing, the finished product is hollow in the middle and has a C-shaped groove structure at the edge.

[0033] To manufacture the aforementioned products, the present invention provides an intelligent production line for filter holders, comprising a workbench 1 and, arranged thereon, a closing device, a punching device, a semicircular forming device, and a synchronous robot. The workbench 1 can be a conventional stamping workbench 1 . The synchronous robot comprises a robot guide rail 9 and four gripping mechanisms mounted thereon. The gripping mechanisms are preferably vacuum suction cups or pneumatic fingers.

[0034] There are three processing steps arranged on the workbench 1, namely closing, punching and semi-circular forming. The synchronous manipulator configured for the three steps has four clamping mechanisms, which can realize the simultaneous processing of material picking, closing, punching and semi-circular forming, which can make the processing process more efficient.

[0035] The function of the closing device is to punch the vertical shape at the edge of the disc 914 into an outer edge of a closing shape that bends inward with a certain curvature. The closing device includes a closing punch 2, a closing upper mold 3, and a closing lower mold 4; the cavity of the closing lower mold 4 is used to accommodate the disc, and the interior of the closing upper mold 3 has a frustum-shaped closing cavity 5. When the workpiece disc is placed on the closing lower mold 4, the closing upper mold 3 is pressed down, and the edge of the disc just contacts the inner wall of the closing cavity 5 of the closing upper mold 3. The closing upper mold 3 is continuously pressed down, and because the closing is formed in an inclined surface, the edge of the disc is continuously squeezed inward to close.

[0036] The punching device punches out the middle portion of the closing disc 913, leaving a channel in the middle. The punching device includes a punching press 6, a punching upper die 7, and a punching lower die 8. The upper cavity 14 of the punching lower die 8 is used to place the workpiece. Below the upper cavity 14 is the punching cavity 15, and the diameter of the upper cavity 14 is larger than the punching cavity 15. The punching upper die 7 is equipped with a positioning ring 16 and a spring 17. The spring 17 is arranged between the positioning ring 16 and the baffle 18, and the upper die can slide within the positioning ring 16. When the punching upper die 7 descends, it can press down from the upper cavity 14 into the punching cavity 15. The size of the punched disc is the size of the punching cavity 15. The baffle 18 can limit the position of the spring 17 and also has a slip-off function. The spring 17 mainly allows the die to automatically return to its position and also provides a certain buffering force during pressure charging, making the punching process smoother.

[0037] The semicircular forming device includes a support base 901 having a through hole therein. Three modules are mounted within the through hole, including a first module 902, a second module 903, and a third module 904, along with a guide block 905. The first and third modules 902 and 904 are positioned on the shoulders of the guide block 905, while the second module 903 is positioned on the front of the guide block 905. Specifically, the first and third modules 902 and 904 are positioned along the X-axis of the guide block 905, while the second module 903 can be positioned along the Y-axis.

[0038] The three modules form a semicircular structure after being unfolded. During the unfolding process, the first module 902 and the third module 904 unfold in opposite directions, and the second module 903 unfolds outward, thereby increasing the volume of the entire module. In addition, the processing object is a punching disc 912. Therefore, no matter at what angle the punching disc is placed outside the three modules, the punching disc can be stretched to form a semicircular workpiece with a semicircular structure.

[0039] The three modules are movably connected to the guide block 905; the guide block 905 is equipped with a pushing device 908, which pushes the guide block 905 to move up and down in the through hole of the support base 901, and when moving upward, the three modules are unfolded and combined to form a semicircular structure. A slide groove or a slide rail is provided on the guide block 905, and corresponding positions on the three modules are provided with slide rails or slide grooves corresponding to the slide groove or slide rail of the guide block 905. For example, if a slide rail is provided on the guide block 905, a slide groove can be provided on the module. If a slide groove is provided on the guide block 905, a protruding slide rail structure is provided on the module, so that the two can move or slide in a straight line relative to each other and remain in the sliding process. It is sufficient to keep it from falling off. The guide part 906 of the guide block 905 gradually increases from top to bottom, so that the guide block 905 can open the three modules during the upward movement and can close the three modules during the downward movement. The connecting portion 907 of the guide block 905 is connected to a driving device 908. The driving device 908 can be a cylinder driving device 908, a motor driving device 908, or a screw driving device 908. The screw driving device 908 is preferably used. For example, the driving device 908 of the guide block 905 includes a slider 909, on which a plurality of screw rods 910 are mounted. The slider contacts the connecting portion 907 of the guide block 905 to drive the guide block 905 to move.

[0040] Preferably, the workbench 1 is provided with a feeding device 11, which has a conveyor belt on which a workpiece disc is placed; a plurality of position sensors are also installed on the workbench 1 for detecting whether there is a workpiece on the mold; the disc is transported from the conveyor belt and can be continuously grabbed by the clamping mechanism 10 and fed into the closing device.

[0041] Preferably, the lower outer edge of the closing upper mold 3 has a guide bevel 12, and the upper edge of the closing lower mold 4 has an outer bevel 13 corresponding to the guide bevel 12; the bevels at the edges of the closing upper mold 3 and the closing lower mold 4 are intended for guidance and also for making the relative movement of the two smoother after contact.

[0042] The present invention also discloses a method for processing a filter support on an intelligent production line of the filter support, comprising the following steps:

[0043] Step (1) controls the first gripping mechanism on the synchronous manipulator to grab the workpiece on the feeding device on the workbench 1 and place it on the closing lower die 4 of the closing device, then starts the closing punch 2 of the closing device, and the closing punch 2 drives the closing upper die 3 to enter the closing lower die 4, and the closing cavity 5 of the closing upper die 3 contacts the outer wall of the workpiece and squeezes and deforms it to form an inward closing shape, and a closing disc is obtained after the closing is completed;

[0044] After the closing device is processed in step (2), the closing punch 2 of the closing device drives the upper mold upward, and then the closing disc processed by the closing device is clamped by the second clamping mechanism on the synchronous manipulator and moved to the punching lower mold 8 of the punching device. At this time, the first clamping mechanism synchronously grabs the workpiece on the feeding device and puts it on the closing lower mold 4;

[0045] Step (3) After the closing disc is placed in the punching lower die 8, the punching press 6 is started to drive the punching upper die 7 downward to punch the closing disc so that a through hole is formed in the inner area of ​​the closing disc to obtain a punched disc. After the punching is completed, the punched disc is moved to the through hole of the semicircular forming device using a third clamping mechanism. During the clamping process of the third clamping mechanism, the first clamping mechanism simultaneously clamps a disc into the closing lower die 4, and the second clamping mechanism clamps the closing disc into the punching lower die 8;

[0046] Step (4) After the punching disc is placed on the semicircular forming device, the pushing device 908 is started to move the guide block 905 upward. The connection between the guide block 905 and the three modules is inclined. During the upward movement of the guide block 905, the three modules are driven to expand horizontally. When expanding, the disc is stretched into the same shape as the semicircle after being formed by the three modules to obtain a semicircular workpiece 911. After the semicircular workpiece is processed, the fourth clamping mechanism is used to remove it from the guide block 905 and then move it to the material receiving device; at this time, the guide block 905 moves downward under the drive of the pushing device 908 and returns to its initial position.

[0047] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
