The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0029] Reference Figure 1 and Figure 2 The waste removal system for covering film cutting provided in this application includes a cutting device 100 and a first removal device.

[0030] The cutting device 100 is used for window cutting of the flexible circuit board cover film 200 roller. The first removal device includes a first roller 310, a second roller 320 and a peeling member. The height of the first roller 310 is lower than the discharge port of the cutting device 100, and the height of the second roller 320 is higher than the first roller 310. The first roller 310 is located between the cutting device 100 and the second roller 320. The peeling member is located above the second roller 320. There is a gap between the peeling member and the top of the second roller 320 to allow the flexible circuit board cover film 200 to pass through.

[0031] In use, the flexible circuit board cover film 200 is window-cut by the cutting device 100. The cut portion of the flexible circuit board cover film 200 first passes around the bottom of the first roller 310, then around the top of the second roller 320, and passes through the gap between the second roller 320 and the peeling member. When the flexible circuit board cover film 200 passes the second roller 320, due to tension, the cover film waste 201 will lift up at the beginning of the running speed, thereby reducing the release force of the waste area at the window position of the flexible circuit board cover film 200, and also facilitating the peeling of the lifted cover film waste 201 by the peeling member. Compared with the existing manual removal, the setting of the first removal device greatly reduces the labor intensity of workers and has high waste discharge efficiency.

[0032] In some embodiments, the peeling element is a scraper or a taut rope. When the peeling element is a scraper, the length of the scraper is the same as the length of the second roller 320, and the gap between the scraper and the top of the second roller 320 is greater than the thickness of the flexible circuit board cover film 200. When the peeling element is a rope, the rope is taut to facilitate the removal of the raised cover film waste 201.

[0033] In some embodiments, the first removal device further includes a first suction assembly, which includes a first suction box 410 and a first air tube 400. The first suction box 410 is disposed above the second roller 320, with the opening of the first suction box 410 facing the top of the first roller 310. One end of the first air tube 400 is connected to the first suction box 410, and the other end of the first air tube 400 is used to connect to a vacuum suction device.

[0034] During operation, the vacuum suction equipment draws air out of the first suction box 410 through the first air pipe 400, so that suction is generated at the opening of the first suction box 410, so that the cover film waste 201 peeled off by the peeling part can be sucked away, preventing the waste from flying everywhere.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the cover film cutting waste removal system also includes a second removal device, which includes a third roller 330, a fourth roller 340 and an air blowing assembly. The height of the third roller 330 is lower than the height of the second roller 320, and the height of the fourth roller 340 is higher than the height of the third roller 330. The air outlet of the air blowing assembly faces the top of the fourth roller 340.

[0036] By setting a second removal device to remove waste from the flexible circuit board cover film 200 again, waste residue is avoided. Specifically, after passing through the first removal device, the flexible circuit board cover film 200 goes around the bottom of the third roller 330 and then around the top of the fourth roller 340. Due to tension, the remaining cover film waste 201 will lift up at the beginning of the running speed, thereby reducing the release force of the waste area at the window position of the flexible circuit board cover film 200. It also makes it easier to blow away the cover film waste 201 by the air blowing assembly, further improving waste removal and avoiding waste residue.

[0037] In some embodiments, the second removal device further includes a second suction assembly, which includes a second suction box 510 and a second air pipe 500. The second suction box 510 is disposed above the fourth roller 340, with the opening of the second suction box 510 facing the top of the fourth roller 340. One end of the second air pipe 500 is connected to the second suction box 510, and the other end of the second air pipe 500 is used to connect to a vacuum suction device.

[0038] During operation, the vacuum suction equipment draws air out of the second suction box 510 through the second air pipe 500, so that the opening of the second suction box 510 generates suction, so as to suck away the cover film waste 201 blown down by the air blowing component and prevent the waste from flying everywhere.

[0039] In some embodiments, the cover film cutting waste removal system further includes a third removal device 600, which includes a fifth roller 350, a sixth roller 620, and a removal member 640. The height of the fifth roller 350 is lower than the height of the fourth roller 340, and the height of the sixth roller 620 is higher than the height of the fifth roller 350. The removal member 640 is disposed on top of the sixth roller 620 and is used to remove the cover film waste 201 remaining on the flexible circuit board cover film 200.

[0040] By setting a third removal device 600 to perform final waste removal on the flexible circuit board cover film 200, waste residue is avoided. Specifically, after passing through the second removal device, the flexible circuit board cover film 200 goes around the bottom of the fifth roller 350 and then around the top of the sixth roller 620. Due to tension, the remaining cover film waste 201 will lift up at the beginning of the running speed, thereby reducing the release force of the waste area at the opening position of the flexible circuit board cover film 200. It also makes it easier to blow away the cover film waste 201 by the removal component 640, further improving waste removal and avoiding waste residue.

[0041] Among them, such as Figure 6As shown, the removal component 640 includes a scraping section and an air blowing section. The scraping section faces the top of the sixth roller 620, and the air outlet of the air blowing section is located on the top of the scraping section, facing the top of the sixth roller 620. The air blowing section further blows up the waste material that is not significantly raised, so that the remaining waste material can be removed by the scraping section. The waste material in the cutting area of ​​the flexible circuit board cover film 200 after passing through the third removal device 600 can be almost completely removed.

[0042] In some embodiments, such as Figure 5 As shown, the third removal device 600 also includes a suction box 610, which is positioned above the sixth roller 620 and is connected to a vacuum suction device. The vacuum suction device generates suction within the suction box 610, thereby removing the blown-away or peeled waste material.

[0043] In some embodiments, an antistatic component 630 is further provided between the fifth roller 350 and the sixth roller 620. The antistatic component 630 is used to eliminate static electricity on the flexible circuit board cover film 200, preventing peeled or blown-away waste from sticking back to the cover film due to static electricity.

[0044] In some embodiments, the cover film cutting waste removal system further includes a waste discharge detection device 700, a cutting device 800, and a receiving machine 900 arranged in sequence. The waste discharge detection device 700 receives the flexible circuit board cover film 200 conveyed from the third removal device 600, the cutting device 800 is used to cut the flexible circuit board cover film 200 into pieces, and the receiving machine 900 is used to stack the cut flexible circuit board cover film pieces 200.

[0045] The waste discharge detection device 700 can monitor the waste discharge status in real time, and will promptly alarm if there is residual waste. It will also generate an image, display and record the location of the unremoved waste, making it easy to clean (after cutting the film, manually remove the film with incomplete waste discharge, and then adjust the equipment until the subsequent film has no incomplete waste discharge).

[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
