Description

Technical Field

[0001] This utility model relates to the field of terminal processing technology, and in particular to a strip cutting device for spring window. Background Technology

[0002] With the rapid development of technology, precision components are increasingly used in electrical appliances. These precision components are relatively small, and to facilitate their processing, they are usually connected together using a long strip of material. By positioning and conveying the material strip, these precision components are transported and processed. However, after processing or packaging, the material strip needs to be cut to carry out subsequent steps for these precision components. Currently, the common method on the market is to manually cut or break the material strip. This manual method is time-consuming and labor-intensive, and it is easy to damage other parts of these precision components when cutting or breaking the material strip, affecting the yield of finished products and failing to meet the needs of today's rapidly developing production. Utility Model Content

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0005] A strip cutting device for a spring-loaded window includes a feeding track mounted on a platform for conveying the spring-loaded window, an upper limit mechanism mounted on the platform and facing the feeding track, and a lower cutting mechanism mounted on the platform, located below the feeding track, and protruding upward. The spring-loaded window includes a spring body conveyed within the feeding track and a strip connected to the spring body and integrally formed into a long strip. At least one flap is formed at one end of the spring body facing the strip and connected to the strip at its tail end. At least one connecting strip is formed at one end of the strip facing the flap and connected to the flap. The lower cutting mechanism includes a lower lifting cylinder mounted on the platform and at least one cutting post mounted on the lower lifting cylinder and passing through the feeding track to cut the connecting strip.

[0006] As a further improvement of this utility model, the upper end of the cutting column protrudes with all the broken ends that pass through the feeding track, and the upper end of the cutting head forms all the cross-sections that extend obliquely from one end of the folded piece downwards to one end of the feeding strip upwards.

[0007] As a further improvement of this utility model, the lower cutting mechanism further includes a lower cutting bracket disposed on the platform, a lower lifting plate disposed on the output shaft of the lower lifting cylinder, at least one lower cutting guide rail disposed on the lower cutting bracket, and at least one lower cutting slider with one end slidably disposed on the lower cutting guide rail and the other end fixed to the lower lifting plate. The lower lifting cylinder is disposed on the lower cutting bracket, and the cutting column is disposed on the lower lifting plate.

[0008] As a further improvement of this utility model, the upper limit mechanism includes an upper limit bracket mounted on a platform, an upper lifting cylinder mounted on the upper limit bracket and extending downward along its output axis, an upper limit seat mounted on the output shaft of the upper lifting cylinder, and at least one upper limit post mounted on the upper limit seat and pressing against the spring window.

[0009] As a further improvement of this utility model, the lower end of the upper limit post is formed with a first pressing block that presses against the spring window and a second pressing block that presses against the connecting strip, and a cutting clearance groove is formed between the first pressing block and the second pressing block for the cutting post to move up and down.

[0010] As a further improvement of this utility model, a trapezoidal overall shape with a larger diameter at one end facing the spring body and a smaller diameter at the other end facing the material strip is formed on the lower end surface of the second pressing block.

[0011] As a further improvement of this utility model, the first pressing block has a side wall inclined guide surface that extends from the inside downward to the outside upward on both sides.

[0012] As a further improvement of this utility model, the upper limit mechanism further includes at least one upper limit guide rail disposed on the upper limit bracket, and at least one upper limit slider with one end sliding on the upper limit guide rail and the other end fixed to the upper limit seat.

[0013] The beneficial effects of this utility model are as follows:

[0014] This strip cutting device is configured to include a feeding track mounted on a platform for conveying a spring-loaded window, an upper limit mechanism mounted on the platform and facing the feeding track, and a lower cutting mechanism mounted on the platform, located below the feeding track and protruding upwards. The spring-loaded window includes a spring body conveyed within the feeding track and a strip connected to the spring body and integrally formed into a long strip. At least one flap is formed at one end of the spring body facing the strip, connecting to the strip at its tail end. At least one connecting strip is formed at one end of the strip facing the flap, connecting to the flap. The lower cutting mechanism includes a lower lifting cylinder mounted on the platform and at least one cutting post mounted on the lower lifting cylinder and passing through the feeding track to cut the connecting strip. The spring-loaded window is conveyed via the feeding track to a position directly opposite the upper limit mechanism. The upper limit mechanism presses downwards, fixing the spring-loaded window in place, effectively preventing displacement of the spring-loaded window when the strip is cut, thus improving the cutting accuracy of this strip cutting device. The lower lifting cylinder in the lower cutting mechanism is activated, driving the cutting column connected to it to move upward. After passing through the feeding track, the cutting column cuts off the connection between the folded piece and the connecting strip, and bends the folded piece, facilitating its subsequent re-bending. The entire process is simple and convenient, requiring no manual intervention, saving time and effort. Furthermore, under the pressure of the upper limit mechanism, the cutting column can precisely cut off the connection between the folded piece and the connecting strip without damaging other structures, effectively ensuring the yield rate of subsequent finished products, improving production efficiency, and meeting the needs of rapidly developing production.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Please refer to Figures 1 to 11 This utility model embodiment provides a material strip 42 cutting device for a spring window 4, including a feeding track 1 mounted on a platform and conveying the spring window 4, an upper limit mechanism 2 mounted on the platform and facing the feeding track 1, and a lower cutting mechanism 3 mounted on the platform, located below the feeding track 1 and protruding upward. The spring window 4 includes a spring body 41 conveyed in the feeding track 1 and a material strip 42 connected to the spring body 41 and integrally formed into a long strip. The end of the spring body 41 facing the material strip 42 has at least one flap 411 whose tail end is connected to the material strip 42. The end of the material strip 42 facing the flap 411 has at least one connecting strip 421 connected to the flap 411. The lower cutting mechanism 3 includes a lower lifting cylinder 31 mounted on the platform and at least one cutting column 32 mounted on the lower lifting cylinder 31 and passing through the feeding track 1 to cut the connecting strip 421.

[0033] The spring-loaded window 4 is conveyed to the position of the upper limit mechanism 2 via the feeding track 1. The upper limit mechanism 2 presses downward to fix the spring-loaded window 4, effectively preventing it from shifting when the strip 42 is cut, thus improving the cutting accuracy of the strip 42 cutting device. The lower lifting cylinder 31 in the lower cutting mechanism 3 is activated, driving the cutting column 32 connected to it to move upward. After passing through the feeding track 1, the cutting column 32 cuts the connection between the folded piece 411 and the connecting strip 421, and bends the folded piece 411, facilitating its subsequent re-bending. The entire process is simple and convenient, requiring no manual intervention, saving time and effort. Under the pressure of the upper limit mechanism 2, the cutting column 32 can accurately cut the connection between the folded piece 411 and the connecting strip 421 without damaging other structures, effectively ensuring the yield rate of subsequent finished products, improving production efficiency, and meeting the needs of rapid production development.

[0034] Regarding the specific method by which the cutting post 32 cuts the flap 411 and the connecting strip 421, as follows: Figure 6 , Figures 9 to 11As shown, the upper end of the cutting column 32 protrudes with a cut-off head 321 that penetrates through the feeding track 1. The upper end of the cutting head 321 forms a cut-off surface 322 that extends obliquely from one end of the folding plate 411 downwards and upwards from one end of the feeding strip 42. Driven by the lower lifting cylinder 31, the cutting head 321 penetrates through the feeding track 1 and aligns with the position where the folding plate 411 and the connecting strip 421 are connected. The cutting head 321 continues to be driven by the lower lifting cylinder 31. Since the cut-off surface 322 is self- The structure of the folding piece 411 extending downwards and upwards towards the material belt 42 at one end has a pointed end that cuts off the connection between the folding piece 411 and the connecting belt 421. Under the inclined guiding action of the switching surface, the folding piece 411 is bent by the cutting surface 322, thus preparing for the subsequent bending of the folding piece 411 back into place, effectively improving production efficiency. Furthermore, the pointed structure formed by the inclined surface is more conducive to applying force to cut off the connection between the folding piece 411 and the connecting belt 421, improving cutting efficiency.

[0035] For other structural configurations of the lower cutting mechanism 3, such as Figure 2 , Figure 5 As shown, the lower cutting mechanism 3 further includes a lower cutting bracket 33 mounted on the platform, a lower lifting plate 34 mounted on the output shaft of the lower lifting cylinder 31, at least one lower cutting guide rail 35 mounted on the lower cutting bracket 33, and at least one lower cutting slider 36 with one end slidably mounted on the lower cutting guide rail 35 and the other end fixed to the lower lifting plate 34. The lower lifting cylinder 31 is mounted on the lower cutting bracket 33, and the cutting column 32 is mounted on the lower lifting plate 34. The lower cutting bracket 33 is used to support the structure of the lower lifting cylinder 31, the lower lifting plate 34, etc. By setting the lower cutting guide rail 35 and the lower cutting slider 36, when the lower lifting cylinder 31 drives the lower lifting plate 34 to move, the lower cutting slider 36 fixed on the lower lifting plate 34 is on the lower cutting guide rail 35, so that the lower lifting plate 34 is limited by the stroke of the lower lifting guide rail, effectively preventing the lower lifting plate 34 from shifting under the drive of the lower lifting cylinder 31, which would cause the cutting column 32 set on the lower lifting plate 34 to be unable to accurately cut between the folded piece 411 and the connecting strip 421, thus effectively improving the cutting accuracy and cutting efficiency of the material strip cutting device.

[0036] Regarding the specific structural configuration of the upper limit mechanism 2, as follows: Figures 7 to 11The upper limit mechanism 2 includes an upper limit support 21 mounted on a platform, an upper lifting cylinder 22 mounted on the upper limit support 21 and extending downward along its output axis, an upper limit seat 23 mounted on the output shaft of the upper lifting cylinder 22, and at least one upper limit post 24 mounted on the upper limit seat 23 and pressing against the spring clip window 4. The upper limit support 21 supports the upper lifting cylinder 22, the upper limit seat 23, and other structures. When the upper lifting cylinder 22 is activated, it drives the upper limit seat 23 mounted on it to move downward, thereby aligning the upper limit post 24 mounted on the upper limit seat 23 with the spring clip window 4 and pressing against it, thus limiting and fixing the spring clip window 4. This effectively prevents the spring clip window 4 from shifting when the strip 42 is cut, improving the cutting accuracy of this strip cutting device.

[0037] Regarding the specific method by which the upper limit post 24 presses against the spring window 4, as follows: Figures 8 to 11 As shown, the lower end of the upper limit post 24 has a first pressing block 241 that presses against the spring window 4 and a second pressing block 242 that presses against the connecting strip 421. A cutting clearance groove 243 is formed between the first pressing block 241 and the second pressing block 242 to allow the cutting post 32 to move up and down. The folded piece 411 is located in the cutting clearance groove 243. The lifting cylinder 22 drives the upper limit post 24 to move downward. The first pressing block 241 presses against the spring body 41, while the second pressing block 242 presses against the connecting strip 421. The cutting head 321 passes through the feeding track 1 and continues to move upward along the inner side wall of the second pressing block 242, thereby cutting off the position where the folded piece 411 in the cutting clearance groove 243 connects to the connecting strip 421 and bending the folded piece 411, which is convenient for subsequent bending of the folded piece 411 into place. The whole process is simple and convenient, requiring no human intervention, saving time and effort. Under the pressure of the second pressing block 242, the cutting column 32 can precisely cut the connection between the folded piece 411 and the connecting strip 421 without cutting the connecting strip 421 and causing adhesion, and without damaging other structures, effectively ensuring the yield of subsequent finished products, improving production efficiency, and meeting the needs of high-speed development.

[0038] Preferred, such as Figure 8 , Figure 11As shown, in order to better press the connecting strip 421 against the second pressing block 242, a pressing limiting plate 2421 is formed on the lower end surface of the second pressing block 242. The plate is trapezoidal in shape, with a larger diameter at the end facing the spring body 41 and a smaller diameter at the end facing the material strip 42. When the upper limit post 24 is pressed down, the pressing limiting plate 2421 presses against the connecting strip 421. Due to its trapezoidal structure with a larger diameter at the end facing the spring body 41 and a smaller diameter at the end facing the material strip 42, its wider end presses against the end of the connecting strip 421 near the fold 411. This further prevents the connecting strip 421 from being moved when the cutting head 321 cuts the connection between the fold 411 and the connecting strip 421, which would cause the subsequent spring window 4 to be transferred and not be accurately processed.

[0039] Preferred, such as Figure 8 As shown, in order to make it easier for the first pressing block 241 to press against the spring body 41, the first pressing block 241 has a side wall inclined guide surface 2411 that extends from the inner lower to the outer upper on both sides. When the first pressing block 241 is placed on the spring body 41, the side wall inclined guide surface 2411 first contacts the side wall of the spring body 41. Under the inclined guiding action of the side wall inclined guide surface 2411, the first pressing block 241 is more easily inserted into the middle of the spring body 41, thereby pressing the middle of the spring body 41, realizing the limiting and fixing of the spring body 41, preventing the spring body 41 from shifting during cutting, which would lead to inaccurate cutting and improve the cutting accuracy of the material strip cutting device.

[0040] Preferred, such as Figure 2 , Figure 7 As shown, the upper limit mechanism 2 also includes at least one upper limit guide rail 25 disposed on the upper limit bracket 21 and at least one upper limit slider 26 with one end sliding on the upper limit guide rail 25 and the other end fixed on the upper limit seat 23. When the lifting cylinder 22 drives the upper limit seat 23 to move downward, the upper limit seat 23 drives the upper limit slider 26 to slide on the upper limit guide rail 25, thereby limiting the stroke of the upper limit seat 23 by the upper limit guide rail 25, effectively preventing the upper limit seat 23 from shifting during the driving process, causing the upper limit column 24 on it to fail to accurately press the spring window 4, thereby effectively improving the cutting accuracy of the material strip cutting device.

[0041] It should be noted that the strip cutting device for the spring window disclosed in this utility model is an improvement on the specific structure, but the specific control method is not an innovation of this utility model. The cylinders, guide rails, sliders, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structures, principles, and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
