[0028] In this embodiment, the waste cleaning plate 33 is a common tool in the waste cleaning process in the prior art, a plurality of cutouts are arranged on the surface of the waste cleaning plate 33, the shape of the cutouts is the same as that of the cutouts on the flexible thin metal plate after die cutting, and the size of the cutouts is slightly larger than that of the cutouts on the flexible thin metal plate after die cutting. The lower frame 32 is used to place the waste cleaning plate 33, and the waste cleaning plate 33 can be fixed on the top of the lower frame 32 by bolts or a toothed rack. The upper frame 34 is driven by the driving mechanism 35 to realize reciprocating movement up and down inside the shell 31, part of the upper ejector assembly 36 is arranged at the bottom of the upper frame 34 and moves with the upper frame 34, and the other part of the upper ejector assembly 36 is fixedly installed at the bottom of the top wall of the shell 31. The upper ejector assembly 36 and the lower ejector assembly 37 cooperate to realize the waste cleaning function, and the polishing assembly 38 cooperates with the upper ejector assembly 36 and the lower ejector assembly 37 to polish burrs at the cutout during the waste cleaning process. Preferably, the driving mechanism 35 is a pneumatic cylinder.

[0029] By arranging the upper ejector assembly 36, the lower ejector assembly 37 and the polishing assembly 38, burrs at the cutout edge of the flexible metal plate can be removed at the same time when the waste cleaning process is performed, the steps of taking out the workpiece, secondary positioning and additional deburring in the traditional process are omitted, the production cycle is significantly shortened, the labor intervention cost is reduced, and the precision loss or product damage caused by handling is avoided.

[0030] As Figure 3 , Figure 4 , Figure 5 shown, the upper ejector assembly 36 comprises an upper ejector 361 and a pin column 363, the upper ejector 361 is rotatably connected to the bottom of the upper frame 34, a helical groove 362 is arranged on the outer side wall of the upper ejector 361, the pin column 363 is fixedly installed at the bottom of the top wall of the shell 31, and the pin column 363 is inserted into the helical groove 362.

[0031] In this embodiment, the upper ejector pin 361 is rotatably connected to the bottom of the upper frame 34 via a bearing. The spiral groove 362 cooperates with the pin 363 to realize the automatic rotation of the upper ejector pin 361 during the lifting process, thereby driving the grinding disc 384 and the grinding block 3810 to rotate, processing the incision edge in all directions to ensure the thorough removal of burrs. Since the pin 363 and the upper ejector pin 361 are in hard contact, industrial grade lubricant should be applied to the pin 363 and the spiral groove 362, and the pin 363 should be reinforced. The setting of the pin 363 should be as follows: Figure 3 As shown, a number of reinforcing beams are provided to reinforce the pin 363 by utilizing the most stable characteristic of a triangle.

[0032] During use, the driving mechanism 35 drives the upper frame 34 and the upper ejector 361 to move up and down. The spiral groove 362 on the upper ejector 361 cooperates with the pin 363, and the upper ejector 361 will rotate as the upper frame 34 moves up and down.

[0033] like Figures 4-10 As shown, the grinding assembly 38 includes a sliding chamber 381, a sliding column 383, a grinding disk 384, a first spring 385, a lower chamber 386, a sliding block 387, a rotating bracket 388, a torsion spring 3811 and a groove 3812. The sliding chamber 381 is opened inside the upper ejector 361, and a through hole 382 is opened on the inner wall of the sliding chamber 381. The sliding columns 383 are arranged in pairs and are arranged inside the sliding chamber 381. The grinding disk 384 is slidably connected to the outer wall of the sliding column 383. The first spring 385 is arranged in pairs and is arranged above the grinding disk 384 and sleeved on the outer wall of the sliding column 383. The lower chamber 386 is opened on the circumferential side wall of the upper ejector 361 and is arranged below the sliding chamber 381. 386 is internally connected to the sliding chamber 381, the lower end of the sliding column 383 extends into the lower chamber 386, the sliding block 387 is slidably connected to the outer wall of the sliding column 383 and is arranged below the grinding disk 384, the rotating bracket 388 is C-shaped and is rotatably connected to the sliding block 387, one end of the rotating bracket 388 is installed with a universal ball 389, and the other end of the rotating bracket 388 is installed with a grinding block 3810, a torsion spring 3811 is arranged inside the sliding block 387, one end of the torsion spring 3811 is fixedly connected to the sliding block 387, and the other end of the torsion spring 3811 is connected to the rotating bracket 388, a groove 3812 is opened at the bottom of the grinding disk 384, and the rotating bracket 388 can enter the groove 3812.

[0034] In this embodiment, the sliding chamber 381, the sliding column 383 and the lower chamber 386 are arranged at positions as follows: Figure 7 、 Figure 9As shown, the slide posts 383 are arranged in pairs, with the lower end of one slide post 383 extending into the interior of the lower chamber 386, and the slide block 387 and the polishing disc 384 slide in relation to the same slide post 383, and the slide block 387 can slide upward along the slide post 383 into the interior of the slide chamber 381 together with the polishing disc 384.

[0035] The specific shape of the polishing disc 384 is as shown in Figure 6 As shown, the polishing disc 384 extends to the exterior of the upper needle 361 through the through hole 382, and the axial portion of the polishing disc 384 is located in the slide chamber 381 and is in sliding connection with the slide post 383, and the slide posts 383 arranged in pairs can provide a limit for the polishing disc 384, while making the polishing disc 384 rotate in unison with the upper needle 361. The bottom of the polishing disc 384 is provided with a groove 3812, and the shape of the groove 3812 is as shown in Figure 6 、 Figure 9 As shown, the width of the groove 3812 is the same as the width of the opening of the lower chamber 386, and the rotating bracket 388 can enter the groove 3812 from the lower chamber 386. The setting position of the first spring 385 is as shown in Figure 7 As shown, the first spring 385 is arranged between the polishing disc 384 and the top wall of the slide chamber 381, and the first spring 385 pushes the polishing disc 384 downward.

[0036] The shape of the rotating bracket 388 is as shown in Figure 8 、 Figure 9 As shown, the upper end of the rotating bracket 388 is provided with a universal ball 389, and the lower end of the rotating bracket 388 is provided with a polishing block 3810; by arranging the universal ball 389, the friction between the upper end of the rotating bracket 388 and the upper surface of the flexible thin metal plate can be reduced. The thickness of the rotating bracket 388 is related to the thickness of the flexible thin metal plate, and when different flexible thin metal plates are replaced, the corresponding rotating bracket 388 needs to be adapted. It is worth noting that the polishing disc 384 and the polishing block 3810 are structures with a plurality of hard bristles on the surface in actual application, and when they contact the cutout, they will produce a certain degree of elastic deformation.

[0037] Figure 13 As shown, the working state of the rotating bracket 388 when the upper needle 361 is not lowered, under the action of the torsion spring 3811, the rotating bracket 388 is in the position as shown. Figure 13 As shown, the working state of the rotating bracket 388 when the upper needle 361 is not lowered, under the action of the torsion spring 3811, the rotating bracket 388 is in the position as shown.

[0038] The working process of the polishing assembly 38 is closely related to the upper needle 361, and mainly includes four stages: 1. The upper needle 361 is lowered and continuously rotated during the lowering process, and the universal ball 389 at the upper end of the rotating bracket 388 first contacts the upper surface of the flexible thin metal plate; 2. The upper needle 361 continues to descend, and the rotating bracket 388 rotates, so that the polishing block 3810 at the lower end of the rotating bracket 388 abuts against the bottom position of the cutout; 3. The upper needle 361 continues to descend, and the rotating bracket 388 enters the groove 3812 together with the sliding block 387, and moves upward together with the polishing disc 384 into the sliding chamber 381 and compresses the first spring 385, the first spring 385 exerts downward pressure, so that the polishing disc 384 abuts against the surface of the cutout, and the polishing block 3810 also abuts against the lower surface of the cutout, and the polishing disc 384 and the polishing block 3810 rotate with the upper needle 361 and polish the upper and lower surfaces of the cutout at the same time.

[0039] 4. The upper needle 361 ascends, the first spring 385 releases the deformation and continues to exert downward pressure, the polishing disc 384 and the polishing block 3810 rotate in the opposite direction and polish the cutout, and as the upper needle 361 continues to ascend, the rotating bracket 388 and the sliding block 387 return to the lower chamber 386, and as the contact between the universal ball 389 and the upper surface of the flexible thin metal plate gradually disappears, the rotating bracket 388 returns to the inside of the lower chamber 386 under the action of the torsional spring 3811.

[0040] As shown in Figure 9 , Figure 13 , the inner side wall of the lower chamber 386 is provided with a stop block 3813 for limiting the sliding block 387. The function of the stop block 3813 is to limit the sliding block 387 when it is inside the lower chamber 386, so that the rotating bracket 388 does not come into contact with the inner wall of the lower chamber 386, ensuring that the rotating bracket 388 can smoothly enter the lower chamber 386.

[0041] As shown in Figure 5 , the circumferential side wall of the upper needle 361 is provided with a polishing layer 3814. The polishing layer 3814 has a structure with a plurality of hard bristles on the surface, and the polishing layer 3814 protrudes from the through hole 382 and the opening of the lower chamber 386 and avoids the through hole 382 and the opening of the lower chamber 386. The advantage of this is that when the upper needle 361 enters the cutout, the polishing layer 3814 will polish the side wall of the cutout, while avoiding friction between the through hole 382 and the opening of the lower chamber 386 and the side wall of the cutout to damage the side wall of the cutout.

[0042] As shown in Figure 7 , Figure 9As shown, the bottom of the upper ejector pin 361 is provided with a through hole 364 for preventing adhesion. One end of the through hole 364 is provided at the bottom center of the upper ejector pin 361, and the other end of the through hole 364 extends into the sliding chamber 381, so that the through hole 364 can be communicated with the external atmospheric pressure. The upper ejector pin 361 ejects the cut-out waste material from top to bottom. The waste material is easy to adhere to the bottom of the upper ejector pin 361, which affects the next waste cleaning work. The through hole 364 can generate a micro air flow during the movement of the upper ejector pin 361, which further reduces the possibility of adhesion of the waste material to the upper ejector pin 361.

[0043] As shown in Figure 4 , Figure 11 , the lower ejector pin assembly 37 includes a mounting column 371, a lower ejector pin 373, a second spring 374, and an anti-adhesion assembly 375. The mounting column 371 is mounted at the bottom of the housing 31, and the top of the mounting column 371 is provided with a mounting chamber 372. The lower ejector pin 373 is slidingly connected in the mounting chamber 372. The second spring 374 is arranged inside the mounting chamber 372 and below the lower ejector pin 373. The second spring 374 is used to push the lower ejector pin 373 to move upward. The anti-adhesion assembly 375 is arranged at the top of the lower ejector pin 373.

[0044] In this embodiment, the lower ejector pin assembly 37 is used in cooperation with the upper ejector pin assembly 36 to perform the waste cleaning process.

[0045] In use, the upper ejector pin 361 descends and presses on the cut-out portion. The upper ejector pin 361 continues to move downward and contacts the top of the lower ejector pin 373. The upper ejector pin 361 continues to descend and cooperates with the lower ejector pin 373 to make the waste material at the cut-out portion separate. At this time, the second spring 374 in the mounting chamber 372 is compressed, so that the lower ejector pin 373 descends synchronously with the upper ejector pin 361. When the upper ejector pin 361 rises, the lower ejector pin 373 rises to the original position under the action of the second spring 374.

[0046] As shown in Figure 11 , Figure 12 , the anti-adhesion assembly 375 includes an ejection chamber 3751, an ejection ball 3752, and a third spring 3753. The ejection chamber 3751 is provided at the top of the lower ejector pin 373. The ejection ball 3752 is arranged inside the ejection chamber 3751, and the top of the ejection ball 3752 can pass through the ejection chamber 3751. The third spring 3753 is arranged inside the ejection chamber 3751 and below the ejection ball 3752. The third spring 3753 is used to push the ejection ball 3752 to move upward.

[0047] In the embodiment, the upper ejector pin 361 cooperates with the lower ejector pin 373 to separate the waste at the cutout, and the waste is prone to adhere to the top of the lower ejector pin 373, affecting the next waste cleaning work; by setting the anti-adhesion assembly 375 on the lower ejector pin 373, the waste adhered to the top of the lower ejector pin 373 is effectively prevented, the frequency of cleaning during shutdown is reduced, and the continuous operation capacity of the equipment is improved.

[0048] In use, the upper ejector pin 361 descends to contact the top of the lower ejector pin 373, pushes the ejection ball 3752 into the inside of the ejection chamber 3751, and compresses the third spring 3753; when the upper ejector pin 361 rises, the third spring 3753 restores the deformation, pushes the top of the ejection ball 3752 out of the ejection chamber 3751, and the ejection ball 3752 can push the adhered waste to make the waste fall off.

[0049] The use process of the embodiment of the application is as follows: First, the driving mechanism 35 drives the upper frame 34 and the upper ejector pin 361 to move up and down, the helical groove 362 on the upper ejector pin 361 cooperates with the pin column 363, and the upper ejector pin 361 will rotate during the movement up and down with the upper frame 34; Second, the upper ejector pin 361 descends and presses on the cutout, continues to move downward to contact the top of the lower ejector pin 373, and the upper ejector pin 361 continues to descend and cooperates with the lower ejector pin 373 to separate the waste at the cutout; In this process, the polishing assembly 38 performs the following process: 1. The upper ejector pin 361 descends and continuously rotates during the descent, and when the upper ejector pin 361 enters the cutout, the polishing layer 3814 polishes the sidewall at the cutout, and the universal ball 389 at the upper end of the rotating support 388 first contacts the upper surface of the flexible thin metal plate; 2. The upper ejector pin 361 continues to descend, the rotating support 388 rotates, so that the polishing block 3810 at the lower end of the rotating support 388 abuts against the bottom position of the cutout; 3. The upper ejector pin 361 continues to descend, the rotating support 388 and the sliding block 387 enter the groove 3812 together, and move upward into the sliding chamber 381 together with the polishing disc 384 and compress the first spring 385, the first spring 385 exerts a downward pressure, so that the polishing disc 384 tightly abuts against the surface of the cutout, and the polishing block 3810 also abuts against the lower surface of the cutout, and the polishing disc 384 and the polishing block 3810 rotate with the upper ejector pin 361 and polish the upper and lower surfaces of the cutout at the same time; 4. The upper ejector pin 361 rises, the first spring 385 releases the deformation, continues to apply pressure downward, the polishing disc 384 and the polishing block 3810 rotate in opposite directions and polish the cutout, as the upper ejector pin 361 continues to rise, the rotating support 388 and the sliding block 387 return to the lower chamber 386, as the contact between the universal ball 389 and the upper surface of the flexible thin metal plate gradually disappears, the rotating support 388 returns to the inside of the lower chamber 386 under the action of the torsional spring 3811; Finally, the upper ejector pin 361 rises back to the preset position, and the above process is repeated to complete the waste removal and deburring process.
