Take-out device and MLCC (Multiplayer Ceramic Chip Capacitor) end capping equipment

Abstract

The utility model relates to a knockout device and MLCC end sealing equipment. The knockout device comprises a fixing piece, a first locking piece, a second locking piece and a cutting wire. One end of the cutting wire is connected to the first locking piece, and the other end is connected to the second locking piece. The tension of the cutting wire can be adjusted through rotation of the first locking piece and / or the second locking piece, and in the scraping circulation process, the cutting wire pushes the bottom of the MLCC product so that the MLCC product can be separated from the silica gel plate. In the process of separating the MLCC products, due to the fact that the cutting wires are thin, more accurate and finer separation can be achieved, and loss of the MLCC products in the separation process is relatively small. When the cutting wire is used for cutting the MLCC product, the generated pressure is small, the deformation and breaking risks of the MLCC product can be reduced, and meanwhile, the scratch of the broken MLCC product to the silica gel plate can also be reduced. Moreover, compared with a sharp cutter, the cutting wire has certain elasticity, and scratches to the silica gel plate can be reduced.

Description

[0003] When preparing the chip capacitor, it is necessary to separate the MLCC product from the silica gel plate of the capping device. At present, in the experiment, a stainless steel blade is used to scrape off the MLCC product. Although the stainless steel blade is convenient to use and low in price, the thickness of the blade edge of the stainless steel blade is thin and the strength is low. When colliding with the MLCC product, it is easy to generate notches, resulting in the MLCC product not being easily scraped off from the silica gel plate, thereby causing scratches on the silica gel plate by the MLCC product, a decrease in the yield rate, and waste of the MLCC product. Summary of the Utility Model

[0034] Hereinafter, embodiments of the technical solutions of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and thus are only examples and cannot be used to limit the protection scope of the present application.

[0035] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "several" is more than one, unless otherwise clearly and specifically defined.

[0036] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the front and back associated objects.

[0037] Referring to "embodiments" herein means that specific features, structures or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0038] The operation of the punching device generally includes the following steps: (1) Feeding cycle: The vacuum arm adsorbs the smooth back surface of the silica gel plate and transports the silica gel plate with MLCC products to the vicinity of the punching device, at the starting position of the scraping cycle; (2) Scraping cycle: The cutting wire is close to the silica gel plate, and the vacuum arm adsorbing the silica gel plate moves a certain distance from left to right. Under the action of the thrust, the MLCC products adhered to the silica gel plate are cut off by the cutting wire and fall into the carrier box; (3) Tray discharging cycle: The vacuum arm sends the silica gel plate into the recycling basket; (4) Cleaning of the punching device: In the scraping cycle, some residues of MLCC products will remain on the cutting wire, and a brush is used to brush off the MLCC products on the cutting wire.

[0039] In a first aspect, an embodiment of the present application provides a punching device 100, which is applied to an MLCC capping device. Please refer to Figure 1 , the punching device 100 includes a fixing member 10, a first locking member 20, a second locking member 30 and a cutting wire 40. The first locking member 20 and the second locking member 30 can fix the cutting wire 40 on the fixing member 10.

[0040] For the above-mentioned fixing member 10, please refer to Figure 1 and Figure 2 , the fixing member 10 includes a first part 11, a second part 12 and a third part 13. The first part 11 and the second part 12 are arranged oppositely, and the third part 13 is connected between the first part 11 and the second part 12. For example, the first part 11, the third part 13 and the second part 12 are connected end to end in sequence, and the connection methods include but are not limited to screw connection, snap connection, welding or bonding, etc. The first part 11, the second part 12 and the third part 13 can be plate-shaped, columnar, etc. Among them, the first part 11 is provided with a first threaded hole 111, and the second part 12 is provided with a second threaded hole 121. The first threaded hole 111 and the second threaded hole 121 are respectively used to install the first locking member 20 and the second locking member 30.

[0041] In some embodiments, the first part 11, the second part 12 and the third part 13 can be integrally formed. The integral formation can improve the structural strength of the fixing member 10, reduce the connection and splicing between parts, make the overall structure of the fixing member 10 more stable, and be able to withstand greater external forces and pressures. And integrally forming the first part 11, the second part 12 and the third part 13 can reduce the error accumulation in the assembly process, make the punching device 100 have higher dimensional accuracy and shape accuracy, simplify the production process, and reduce the production cost.

[0042] For the above-mentioned first locking member 20 and second locking member 30, please refer to Figure 2 and Figure 3, the first locking member 20 is disposed in the first threaded hole 111 and threadedly connected to the first part 11. The first threaded hole 111 is disposed at one end of the first part 11 away from the third part 13. The second locking member 30 is disposed in the second threaded hole 121 and threadedly connected to the second part 12. The second threaded hole 121 is disposed at one end of the second part 12 away from the third part 13. Among them, the first locking member 20 and the second locking member 30 can be screws, studs, bolts, etc.

[0043] For the above-mentioned cutting wire 40, please refer to Figure 1 and Figure 3 , the cutting wire 40 is a kind of slender linear object with high strength, high toughness and not easy to break, and has low cost and simple structure. One end of the cutting wire 40 is connected to the first locking member 20, and the other end is connected to the second locking member 30. The tension of the cutting wire 40 can be adjusted by rotating the first locking member 20 and / or the second locking member 30. During the scraping cycle, the cutting wire 40 pushes the bottom of the MLCC product to facilitate the separation of the MLCC product from the silicone plate. During the separation of the MLCC product, since the cutting wire 40 is relatively thin, more precise and delicate separation can be achieved, and the loss of the MLCC product during the separation process is relatively small. When the cutting wire 40 cuts the MLCC product, the generated pressure is small, which can reduce the deformation and the risk of breakage of the MLCC product. At the same time, it can also reduce the scratching of the silicone plate by the broken MLCC product. Moreover, compared with a relatively sharp tool, the cutting wire 40 can also reduce the scratching of the silicone plate.

[0044] The first locking member 20 can flexibly fix one end of the cutting wire 40 to the first part 11. Similarly, the second locking member 30 can flexibly fix the other end of the cutting wire 40 to the second part 12. When the cutting wire 40 needs to be replaced, only the first locking member 20 and the second locking member 30 need to be adjusted to loosen the cutting wire 40, and then a new cutting wire 40 can be replaced. Among them, the cutting wire 40 can be a wire made of metal wire, organic polymer material, etc. For example, steel wire, copper wire, iron wire, nylon wire, Dyneema wire, carbon line, etc. During use, cutting wires 40 made of different materials can be used according to the situation to meet different cutting requirements.

[0045] An embodiment of the present application provides a punching device 100, which includes a fixing member 10, a first locking member 20, a second locking member 30, and a cutting wire 40. One end of the cutting wire 40 is connected to the first locking member 20, and the other end is connected to the second locking member 30. The tension of the cutting wire 40 can be adjusted by the rotation of the first locking member 20 and / or the second locking member 30. During the scraping cycle, the cutting wire 40 pushes the bottom of the MLCC product to facilitate the separation of the MLCC product from the silicone plate. During the separation of the MLCC product, since the cutting wire 40 is relatively thin, more precise and subtle separation can be achieved, and the loss of the MLCC product during the separation process is relatively small. When the cutting wire 40 cuts the MLCC product, the generated pressure is small, which can reduce the deformation and the risk of breakage of the MLCC product. At the same time, it can also reduce the scratching of the silicone plate by the broken MLCC products. Moreover, compared with a relatively sharp tool, the cutting wire 40 has a certain elasticity, which can reduce the scratching of the silicone plate.

[0046] In some embodiments, please refer to Figure 3 , the punching device 100 further includes a flexible baffle 50. The flexible baffle 50 is a baffle structure with a certain flexibility, usually made of flexible materials, and can generate a certain deformation or bending when subjected to an external force. The flexible baffle 50 is connected between the first part 11 and the second part 12, and the flexible baffle 50 is disposed close to the cutting wire 40. After the cutting wire 40 cuts the MLCC product, the flexible baffle 50 can reduce the MLCC product from flipping and re-adhering to the silicone plate, playing a good shielding role. The flexible baffle 50 can also provide a certain elastic reaction force to the MLCC product, so that the MLCC product is closely attached to the cutting wire 40, reducing the occurrence of burrs and cracks on the MLCC product, and also reducing the phenomenon of the MLCC product adhering to the cutting wire 40. The flexible baffle 50 can be a rubber baffle, a silicone baffle, a fabric baffle, a plastic film baffle, a sponge baffle, etc.

[0047] In some embodiments, please refer to Figure 3 , there is a first distance L between the flexible baffle 50 and the cutting wire 40. If the length of the MLCC product is D, then 0 ≤ L ≤ D. If the distance between the flexible baffle 50 and the cutting wire 40 is too large, the shielding effect of the flexible baffle 50 on the MLCC product is small. When 0 ≤ L ≤ D, the flexible baffle 50 can shield the MLCC product and reduce the phenomenon of the MLCC product adhering to the silicone plate. For example, if the length D of the MLCC product is 0.25 mm, then the first distance L between the flexible baffle 50 and the cutting wire 40 is 0 ≤ L ≤ 0.25 mm.

[0048] In some embodiments, please refer to Figures 3 to 5, on one side of the first part 11 close to the first threaded hole 111, a first hole 112 is provided, and on one side of the second part 12 close to the second threaded hole 121, a second hole 122 is provided. The punching device 100 further includes a third locking member 60 and a fourth locking member 70. Third holes 51 and fourth holes 52 are respectively provided at both ends of the flexible baffle 50. The third locking member 60 is respectively passed through the third hole 51 and the first hole 112 to be connected to the first part 11, and the fourth locking member is respectively passed through the fourth hole 52 and the second hole 122 to be connected to the second part 12, so as to fix the flexible baffle 50 on the fixing member 10. Wherein, the third locking member 60 and the fourth locking member 70 can be screws, studs, bolts, rivets, pins, fixing buckles, etc.

[0049] In some embodiments, the flexible baffle 50 is arranged parallel to the cutting wire 40. During the process of scraping off the MLCC products, the force between the MLCC products and the flexible baffle 50 is uniform, which can reduce the occurrence of skew cutting of the MLCC products.

[0050] In some embodiments, please refer to Figure 6 , the punching device 100 further includes a first strengthening part 14 and a second strengthening part 15. The first strengthening part 14 is arranged between the first part 11 and the third part 13, and the second strengthening part 15 is arranged between the second part 12 and the third part 13. The first strengthening part 14 can enhance the structural strength and stability between the first part 11 and the third part 13, improve the ability of the overall structure of the punching device 100 to withstand external forces, loads and pressures, and reduce the phenomena of deformation, cracking or damage. Make the punching device 100 more stable during use, and reduce shaking, vibration or displacement. Similarly, the second strengthening part 15 can enhance the structural strength and stability between the second part 12 and the third part 13, further improve the ability of the overall structure of the punching device 100 to withstand external forces, loads and pressures, and reduce the phenomena of deformation, cracking or damage. Make the punching device 100 more stable during use, and reduce shaking, vibration or displacement. According to the materials of the first strengthening part 14 and the second strengthening part 15, the first strengthening part 14 and the second strengthening part 15 can be fixed by gluing, threaded connection, welding, etc.

The first part 11 has a first wire groove 114, the first wire groove 114 communicates with the first groove 113, and the first wire groove 114 is arranged from the first part 11 towards the second part 12. The second part 12 has a second wire groove 124, the second wire groove 124 communicates with the second groove 123, and the second wire groove 124 is arranged from the second part 12 towards the first part 11. The wound cutting wire 40 can be received in the first groove 113 and / or the second groove 123 to improve the safety of using the punching device 100. The cutting wire 40 is located in the first wire groove 114 and the second wire groove 124 and extends out through the first wire groove 114 and the second wire groove 124, reducing the disorderly distribution of the cutting wire 40, reducing the damage of the cutting wire 40, and improving the overall aesthetics and orderliness of the punching device 100.
