Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a PET film scraping device. Background Technology

[0002] MLCC (Multi-layer ceramic capacitors) is an abbreviation for multilayer ceramic chip capacitors, which are widely used capacitors in circuits and are also known as "monolithic capacitors".

[0003] The lamination process is a crucial step in MLCC manufacturing. Its main function is to coat ceramic film rolls and sheets from the casting and printing processes onto PET film to form ceramic film rolls. The PET films are then mounted on a laminator for stacking. After the ceramic film sheets are peeled off, the rolls are stacked to the required size and thickness and then moved to the next process. However, the ceramic film rolls peeled off by the laminator cannot be directly reused because they still contain ceramic scraps on the PET film. Furthermore, the lamination process consumes a large amount of PET film, resulting in significant production costs. Therefore, a film scraping function needs to be implemented on the laminator to save costs and achieve continuous improvement. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The technical features designed in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, it should be noted that all terms used in this utility model (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains, and should not be construed as limiting this utility model; it should be further understood that the terms used in this utility model should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this utility model.

[0027] This utility model provides a PET film scraping device, such as... Figure 1 As shown, it includes a scraper mechanism 10, an adhesion and tensioning mechanism 20, and a receiving box 30; the scraper mechanism 10 and the adhesion and tensioning mechanism 20 are arranged sequentially along the transmission direction of the PET film 60, and the receiving box 30 is located at the bottom of the scraper mechanism 10.

[0028] In specific implementation, such as Figure 1 As shown, the film scraping device is installed on the stack and base. The PET film 60 is passed through the film scraping device. The PET film 60 is first fixed to the scraper mechanism 10 and the adhesion tensioning mechanism 20 in sequence. Then the adhesion tensioning mechanism 20 tensions the PET film 60. After that, the scraper mechanism 10 peels off the residual ceramic film 70. The peeled ceramic film 70 falls into the receiving box 30 at the bottom of the scraper mechanism 10.

[0029] like Figure 2 As shown, the scraper mechanism 10 includes a scraper section 110 and a scraper support 120. The scraper section 110 and the scraper support 120 are detachably connected. Two sets of scraper supports 120 are provided, symmetrically arranged on both sides of the scraper section 110. The scraper support 120 supports the scraper section 110 to contact the PET film 60 for peeling off the residual ceramic film 70.

[0030] like Figure 2As shown, the scraper section 110 includes a scraper blade 111 and a blade clamping plate 112. Both ends of the blade clamping plate 112 are connected to the scraper support 120. The top of the blade clamping plate 112 has a receiving space for mounting the scraper blade 111. The scraper blade 111 abuts against the first roller 40 of the laminator, and the PET film 60 passes through the space between the scraper blade 111 and the first roller 40 and is driven forward. Specifically, the left and right ends of the blade clamping plate 112 are connected to the scraper support 120. The blade clamping plate 112 includes a first clamping plate and a second clamping plate, which are stacked together, forming a receiving space for the scraper blade 111 between the two plates. Preferably, the scraper blade 111 can be removed from the receiving space for replacement.

[0031] The top of the doctor blade 111 faces the first roller 40 of the laminator, and the PET film 60 passes through the doctor blade 111 and the first roller 40 and is driven forward. Specifically, the gap between the first roller 40 and the doctor blade 111 is good, and their interaction allows the doctor blade 111 to have a better grip on the PET film 60, ensuring that the doctor blade 111 can remove the ceramic film 70 on the PET film 60 more thoroughly.

[0032] Preferably, the scraper mechanism 10 is further provided with a second roller 50. The second roller 50 is positioned between the first roller 40 and the adhesion tensioning mechanism 20 in the conveying direction of the PET film 60. The bottom of the second roller 50 is opposite to the scraper section 110. The PET film 60 passes through the scraper blade 111 and the second roller 50 and is conveyed forward. Specifically, there are two scraper sections 110. The first scraper section 110 is positioned opposite the first roller 40, and the second scraper section 110 is positioned opposite the second roller 50. The arrangement of the second scraper section 110 and the second roller 50 is to perform a secondary removal of the ceramic film 70 that was not completely removed by the first roller 40 and the first scraper section 110, ensuring a more thorough scraping.

[0033] In one embodiment, such as Figure 2As shown, the scraper support 120 includes a scraper support base 121, a lifting cylinder 122, a scraper support extension plate 123, and a blade holder mounting plate 124. The lifting cylinder 122 is fixed to the scraper support base 121, the bottom of the scraper support extension plate 123 is connected to the top of the lifting cylinder 122, and the blade holder mounting plate 124 is mounted on the side wall of the scraper support extension plate 123. Specifically, because the scraping section is too close to the laminator and the second roller 50 during the actual film scraping process, maintaining the working height of the scraper section 110 after use can easily cause equipment damage. Therefore, after use, the scraping section can be lowered to a preset height by the lifting cylinder 122 of the scraper support 120 to protect the scraper section 110 and prevent damage to the device. Furthermore, the lifting cylinder 122 can better adapt to the height requirements of different laminators, making the film scraping device more versatile.

[0034] In one embodiment, such as Figure 2 As shown, the scraper support extension plate 123 is provided with a first opening 1231, and the blade holder mounting plate 124 is provided with a vertical strip hole 1241. The first opening 1231 and the vertical strip hole 1241 correspond to each other and are detachably connected by a connector. Adjusting the installation position of the first opening 1231 relative to the vertical strip hole 1241 adjusts the fixed position of the blade holder mounting plate 124 relative to the scraper support extension plate 123. Specifically, by changing the positions of the first opening 1231 and the vertical strip hole 1241, the overall position of the blade holder mounting plate 124 can be moved up and down, thereby finely adjusting the position of the scraper blade 111.

[0035] Furthermore, such as Figure 2 As shown, the scraper bracket 120 is also provided with a mounting plate support block 125. The mounting plate support block 125 is fixed to the side wall of the scraper bracket extension plate 123 and located at a preset distance below the blade holder mounting plate 124 to limit the lowest installation position of the blade holder mounting plate 124 relative to the scraper bracket extension plate 123. Specifically, the mounting plate support block 125 limits and supports the blade holder mounting plate 124. When the blade holder mounting plate 124 is at its lowest position relative to the scraper bracket extension plate 123, its bottom will abut against the mounting plate support block 125, and the mounting plate support block 125 can support the blade holder mounting plate 124.

[0036] In one embodiment, there are at least two vertical strip holes 1241. The arrangement of at least two vertical strip holes 1241 ensures the stability of the connection between the tool holder mounting plate 124 and the scraper support extension plate 123.

[0037] In one embodiment, the scraper holder 120 further includes a scraper slide plate 126, which has a second opening 1261. The scraper mounting plate 124 has a horizontal strip hole 1242, with the second opening 1261 corresponding to the horizontal strip hole 1242, and they are detachably connected via a connector. The scraper slide plate 126 is connected to the blade clamping plate 112 and is connected to different positions of the horizontal strip hole 1242 via the second opening 1261 to move the mounting position of the scraper part 110 back and forth. Specifically, the scraper blade 111 can be moved back and forth via the second opening 1261 and the horizontal strip hole 1242, allowing for better positioning of the scraper blade 111 with the first roller 40 and the second roller 50.

[0038] In one embodiment, there are at least two horizontal strip holes 1242, which are spaced at a predetermined distance in the vertical direction and are arranged opposite each other with the same shape. The arrangement of the two horizontal strip holes 1242 can make the tool holder mounting plate 124 and the tool holder sliding plate 126 more stably installed.

[0039] In one embodiment, such as Figure 2 As shown, the blade clamping plate 112 is connected to the blade holder sliding plate 126 via a rotating shaft 113. The blade clamping plate 112 can rotate relative to the blade holder sliding plate 126 in a first or second direction. By setting the rotating shaft 113, the angle of the blade clamping plate 112 can be adjusted, so as to better scrape the PET film 60.

[0040] In one embodiment, such as Figure 2 As shown, the adhesion and tensioning mechanism 20 includes a third roller 210, a fourth roller 220, a roller bracket 230, an adjusting and fixing plate 240, and a roller adjustment structure 250. The line connecting the axes of the third roller 210 and the fourth roller 220 is perpendicular to the horizontal direction. There are two roller brackets 230, symmetrically arranged on both sides of the third roller 210 and the fourth roller 220. Specifically, the third roller 210 and the fourth roller 220 are arranged opposite each other and are relatively close together. Adhesive attachments are provided on the upper part of the third roller 210 and the fourth roller 220, which can adhere and remove impurities from the surface of the PET film 60 after the ceramic diaphragm 70 is removed. At the same time, the third roller 210 and the fourth roller 220 press the PET film 60 together, and can tension the PET film 60 in conjunction with the first roller 40. The roller adjustment structure 250 can adjust the height of the third roller 210 and the fourth roller 220 up and down, thereby adjusting the gap between the third roller 210 and the fourth roller 220 to better adhere and press the PET film 60.

[0041] Preferably, there are four sets of roller adjustment structures 250. Each end of the third roller 210 is connected to a roller adjustment structure 250; each end of the fourth roller 220 is also connected to a roller adjustment structure 250. Specifically, the left and right sides of the third roller 210 and the fourth roller 220 are connected to roller adjustment structures 250 respectively. The roller adjustment structures 250 on both sides of the third roller 210 simultaneously adjust the height of the third roller 210, and the same applies to the fourth roller 220.

[0042] In one embodiment, such as Figure 2 As shown, the adjusting fixing plate 240 is disposed on the top of the roller bracket 230, the roller adjusting mechanism is installed on the roller bracket 230 through the adjusting fixing plate 240, and the roller adjusting structure 250 moves in the vertical direction to adjust the position of the third roller 210 and the fourth roller 220.

[0043] Specifically, such as Figure 2 As shown, the roller adjustment structure 250 includes a support block 251, a roller fixing block 252, and an adjusting screw 253. The support block 251 is fixed to the side wall of the roller bracket 230. The adjusting screw 253 passes through the adjusting fixing plate 240, the roller fixing block 252, and the support block 251 from top to bottom. The third roller 210 or the fourth roller 220 is fixed to the roller fixing block 252. The roller fixing block 252 is fixed to the adjusting screw 253. The adjusting screw 253 moves vertically relative to the adjusting fixing plate 240 and the support block 251, thereby driving the roller fixing block 252 to move vertically.
