Description

Technical Field

[0001] This utility model relates to the field of hardware parts manufacturing technology, and in particular to a precision hardware parts strip with a pressing edge and easy-break structure. Background Technology

[0002] As electronic products become increasingly miniaturized and precise, higher demands are placed on the performance and assembly methods of their internal metal components. Adapter steel sheets, as key metal components used to transmit electrical signals or current within electronic products, play a crucial role. They are typically made of highly conductive metal materials, such as copper, copper alloys, or stainless steel, possessing high conductivity and corrosion resistance to meet the requirements for stable operation of electronic products. In automated assembly processes for electronic products, the automated feeding methods for adapter steel sheets mainly include vibratory feeder feeding, tape feeding, and vision feeding. Vibratory feeder feeding uses a vibratory feeder to arrange and transport the adapter steel sheets to designated positions in an orderly manner; tape feeding is suitable for tape-type adapter steel sheets, automatically feeding them using a tape feeder; vision feeding utilizes a flexible vibratory feeder and a vision robot to achieve directional feeding of the adapter steel sheets.

[0003] However, there is an existing type of adapter steel sheet used as a precision hardware component in electronic products, which has a special structure, such as... Figure 1 As shown, it is made of two thin, right-angled conductive metal strips, about the size of a thumb. This unique structure and size present numerous challenges in supplying the material.

[0004] Difficulty in feeding materials to the vibratory feeder: Due to the small size of the adapter steel plate, it is difficult to achieve a stable and accurate orderly arrangement during the feeding process of the vibratory feeder, resulting in low feeding efficiency and even feeding errors, which cannot meet the high efficiency and precision requirements of automated assembly.

[0005] Limited visual feeding: Due to its small size, it is extremely difficult to perform grasping operations by visual robotic arms. It requires extremely high precision from both the visual recognition system and the robotic arm. In actual operation, problems such as misgrabbing and missed grasping are prone to occur, which seriously affects production efficiency and product quality.

[0006] The issue of tape feeding is prominent: displacement can occur between the winding adapter steel sheets during transportation or use. The unique construction of these adapter steel sheets, consisting of two slender, right-angled conductive metal sections, makes them prone to tangling or jamming when using tape feeding. Furthermore, the slender structure is highly susceptible to deformation when cut from the tape due to its inherent structural instability, affecting product precision and performance, and consequently reducing the product yield.

[0007] In summary, the existing automated feeding method for adapter steel sheets is not well-suited for precision hardware parts with such special structures. There is an urgent need to propose an improved technical solution to solve the aforementioned problems in the automated feeding process and improve the production efficiency and product quality of electronic products. Utility Model Content

[0008] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0009] A precision hardware accessory strip with a pressure edge breakable structure includes a strip body formed by multiple fixed frames connected in sequence. The fixed frames are made of metal sheet. One side of the fixed frame is provided with a pressure edge breakable part. The pressure edge breakable part extends along the inner side of the fixed frame to form a transition section. A transition steel sheet extends at the end of the transition section, and a breakable edge is provided between the transition steel sheet and the transition section. At least one protrusion extends along the inner side of the fixed frame, and the protrusion is vertically bent.

[0010] Preferably, each fixed frame is provided with two sets of protrusions, one set of protrusions is bent vertically along the top of the fixed frame, and the other set of protrusions is bent vertically along the bottom of the fixed frame.

[0011] Preferably, each set of protrusions has two protrusions, and the two protrusions are located on different sides of the fixed frame.

[0012] Preferably, a plurality of first positioning holes are evenly distributed on the fixed frame, and at least one second positioning hole is provided on the easily broken edge.

[0013] Preferably, the front and rear sides of adjacent fixing frames on the main body of the material strip are shared, and the easily broken part of the pressing edge corresponds to the rear position of the fixing frame.

[0014] Preferably, the adapter steel sheet has two slender precision hardware fittings with a right-angle structure, and the easily broken edge is correspondingly formed with two transition sections to form the two precision hardware fittings respectively. Both ends of the precision hardware fittings are provided with welding parts, and the easily broken edge is located between one of the welding parts and the transition section of the precision hardware fitting.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By stamping a breakable edge on one side of the fixed frame, the transfer steel sheet can be easily pried apart along with the breakable edge during material feeding, and the breakable edge can be grabbed and removed from the main body of the strip during production assembly. Simultaneously, a breakable edge is stamped between the transfer steel sheet and the transition section, facilitating the separation of the breakable edge and the transition section after welding. Furthermore, a vertically bent protrusion is provided inside the fixed frame. When the main body of the strip is wound into a multi-layer structure, the protrusion can position two layers by contacting the inner side of adjacent fixed frames, preventing the transfer steel sheet from tangling or jamming; when it abuts against adjacent fixed frames, it separates two layers, reducing the possibility of tangling or jamming of the transfer steel sheet in the same position.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figure 1-4 In this embodiment of the present invention, a precision hardware accessory strip with a pressure edge breakage structure includes a strip body formed by sequentially connecting multiple fixing frames 10. The fixing frames 10 are made of metal sheet. One side of the fixing frame 10 is provided with a pressure edge breakage part 11. The pressure edge breakage part 11 extends along the inner side of the fixing frame 10 to form a transition section 12. A transition steel sheet 20 extends at the end of the transition section 12, and a breakage edge 13 is provided between the transition steel sheet 20 and the transition section 12. At least one protrusion 14 extends along the inner side of the fixing frame 10, and the protrusion 14 is vertically bent.

[0027] In the above technical solution, multiple transition steel sheets 20 are formed on a metal strip by stamping. A fixed frame 10 is used to enclose the transition steel sheets 20. This structural design ensures that each fixed frame 10 provides relatively independent positioning and isolation for the transition steel sheets 20 during the winding process. Furthermore, a structure consisting of a pressure-edge breakage section 11, a transition section 12, and a breakage edge 13 is employed. The pressure-edge breakage section 11 is located on one side of the fixed frame 10, meaning that the edge of the fixed frame 10 is pressed by stamping. Two thin, easily broken edges are provided, and the portion between the two edges forms a pressure-edge breakable section 11, which facilitates easy separation from the fixing frame 10. This design makes it easy to break the adapter steel sheet 20 together with the pressure-edge breakable section 11 during the feeding process. In the production and assembly process of electronic products, the adapter steel sheet 20 can be removed from the main body of the material strip by grasping the pressure-edge breakable section 11. Since an easily broken edge 13 is also provided, the easily broken edge 13 is also stamped out between the adapter steel sheet 20 and the transition section 12 by stamping. After the adapter steel sheet 20 is welded to the designated position... Then, the easily breakable edge 11, along with the transition section 12, is pulled off the adapter steel sheet 20. Furthermore, a protrusion 14 is provided, located inside the fixing frame 10, and vertically bent. During the winding process of the strip body, it forms a multi-layer structure. This protrusion 14 can engage with or abut against the inner side of the corresponding fixing frame 10 of the adjacent outer or inner layer. When it engages with the inner side of the corresponding fixing frame 10 of the outer or inner layer, it can position the two fixing frames 10, ensuring the adjacent strip bodies are aligned. The two layers are more stable and less prone to displacement, which makes it less likely for the transition steel sheets 20 in the same position between two adjacent layers of the material strip to become entangled or jammed. When it abuts against the fixing frame 10 of the adjacent outer or inner layer, it can separate the two adjacent layers of the material strip by a gap of a protrusion 14, so that the transition steel sheets 20 in the same position between two adjacent layers of the material strip can be separated to a certain extent. That is, the setting of the protrusion 14 can reduce the entanglement or jamming between the adjacent transition steel sheets 20 when the material strip is wound.

[0028] Therefore, by stamping a breakable edge 11 on one side of the fixed frame 10, it is convenient to break the transfer steel sheet 20 together with the breakable edge 11 during material feeding, and to grab the breakable edge 11 to remove the transfer steel sheet 20 from the main body of the strip during production assembly. At the same time, a breakable edge 13 is stamped between the transfer steel sheet 20 and the transition section 12, which facilitates the separation of the breakable edge 11 and the transition section 12 after the transfer steel sheet 20 is welded. In addition, a vertically bent protrusion 14 is provided on the inner side of the fixed frame 10. When the main body of the strip is wound into a multi-layer structure, the protrusion 14 can position two layers by contacting the inner side of the adjacent fixed frame 10, preventing the transfer steel sheet 20 from winding or getting stuck. When it abuts against the adjacent fixed frame 10, it separates two layers, reducing the possibility of the transfer steel sheet 20 winding or getting stuck in the same position.

[0029] Please see Figure 3-4 Based on the above embodiments, it is further proposed that each fixed frame 10 is provided with two sets of protrusions 14, one set of protrusions 14 is bent vertically along the upper part of the fixed frame 10, and the other set of protrusions 14 is bent vertically along the lower part of the fixed frame 10; each set of protrusions 14 has two, and the two protrusions 14 are located on different sides of the fixed frame 10. The upper and lower sets of protrusions 14 provide a multi-dimensional positioning method for the multi-layered fixed frames 10 during the winding process of the material strip body. The upper protrusion 14 interacts with the adjacent upper fixed frame 10, and the lower protrusion 14 cooperates with the adjacent lower fixed frame 10. Compared with only one set of protrusions 14, this simultaneous upper and lower positioning method greatly enhances the positioning stability between adjacent fixed frames 10. Regardless of the direction of external force applied to the strip during winding, transportation, or automated feeding, the coordinated action of the upper and lower sets of protrusions 14 effectively maintains the relative position of adjacent fixed frames 10, making the position of the adapter steel sheet 20 more precise across different layers and further reducing the risk of entanglement and jamming due to positional misalignment. Each set has two protrusions 14 located on different sides, positioning the fixed frame 10 from different lateral directions. When the strip is wound, the contact points between the two protrusions 14 at different positions and the adjacent fixed frames 10 form a certain distribution, avoiding rotation or local misalignment of the fixed frame 10 that may be caused by single-point or single-side positioning. This reinforced design with bilateral positioning ensures that the fixed frame 10 is stably constrained in all directions, thereby keeping the adapter steel sheet 20 neat and orderly across all layers of the strip, providing a reliable guarantee for accurate feeding and installation in subsequent automated production.

[0030] Please see Figure 3-4Based on the above embodiments, a further proposed method involves providing a plurality of evenly distributed first positioning holes 15 on the fixed frame 10 and at least one second positioning hole 16 on the easily breakable edge pressing part 11. The first positioning holes 15 are used for positioning and feeding with the equipment during the electronic product manufacturing and assembly process. In this process, the multiple evenly distributed first positioning holes 15 provide a precise positioning reference between the equipment and the material strip. The automated equipment can accurately identify the position and orientation of the fixed frame 10 through these positioning holes, quickly and accurately grasping and conveying the material strip, thus achieving automated feeding of the transfer steel sheet 20. Compared with traditional feeding methods relying on manual labor or lacking clear positioning markings, this method significantly improves positioning accuracy, reduces feeding errors or equipment malfunctions caused by positioning deviations, and thereby improves production efficiency. Simultaneously, the evenly distributed design ensures stable and consistent positioning of the equipment throughout the entire length of the material strip, maintaining efficient and accurate feeding regardless of the material strip's stage of use. The second positioning hole 16 serves to position the adapter steel sheet 20 after it is pried open from the easily broken edge 11. The second positioning hole 16 plays a crucial role after the adapter steel sheet 20 and the easily broken edge 11 are pried open. In subsequent operations, such as welding or installation of the adapter steel sheet 20, the equipment can use the second positioning hole 16 to perform secondary positioning of the easily broken edge 11 and the adapter steel sheet 20, ensuring the accuracy of the adapter steel sheet 20's position after separation from the conveyor belt. This effectively avoids positional shifts that may be caused by the prying action, providing a reliable guarantee for subsequent precise installation. Through this phased positioning method, the positioning accuracy of the entire production process, from conveyor belt feeding to adapter steel sheet 20 installation, is comprehensively improved, contributing to increased product consistency and yield.

[0031] Please see Figure 2 Based on the above embodiments, it is further proposed that the front and rear edges of adjacent fixing frames 10 on the main body of the strip be shared, and the easily breakable edge 11 is located at the rear edge of the fixing frame 10, which can reduce the material consumption of the main body of the strip. The sharing of the front and rear edges of adjacent fixing frames 10 means that, for the same number of adapter steel sheets 20, the total amount of metal sheets used in the main body of the strip is significantly reduced compared to the conventional design where each fixing frame 10 has its own independent front and rear edges. Taking the production of a certain number of adapter steel sheets 20 as an example, this shared edge design can effectively reduce the material length used to manufacture the edges of the fixing frames 10, thereby reducing the overall material cost. In the scenario of large-scale production of electronic products, the small savings in material costs will accumulate into significant economic benefits, enhancing the company's cost competitiveness in the market. Furthermore, by cleverly combining the edges of adjacent fixing frames 10, materials that might otherwise be wasted on the production of independent frames can be fully utilized. This not only improves the output efficiency of unit metal sheets but also reduces the waste generated from cutting excess material, further improving material utilization and enabling a more rational allocation of resources.

[0032] Please see Figure 1-3 Based on the above embodiments, a further proposed design is made where the adapter steel sheet 20 has two slender, right-angled precision hardware components 21. The edge-pressing, easily broken portion 11 is correspondingly formed with two transition sections 12 to form the two precision hardware components 21 respectively. Welding portions 22 are provided at both ends of each precision hardware component 21, and an easily broken edge 13 is positioned between one of the welded portions 22 and the transition section 12 of the precision hardware component 21. The adapter steel sheet 20, with its two slender, right-angled precision hardware components 21 and the edge-pressing, easily broken portion 11 corresponding to the two transition sections 12, is used to form the two precision hardware components 21 respectively. This design precisely matches the special structure of the adapter steel sheet 20, ensuring that during production, each precision hardware component 21 can be stably connected to the edge-pressing, easily broken portion 11 via the transition section 12. During the winding, transportation, and feeding of the material strip, it provides reliable support and positioning for the precision hardware components 21, effectively avoiding deformation and displacement problems caused by structural complexity, and ensuring the accuracy and stability of the product. Furthermore, the two slender, right-angled precision metal fittings 21 often perform special functions in electronic products, requiring extremely high precision in their forming and processing. By using a specially designed transition section 12 in conjunction with the easily breakable edge pressing part 11, the production needs of this complex structure can be better met, making the entire production process more targeted and controllable, thus improving product quality and meeting the increasingly sophisticated development trend of electronic products.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
