Description

Technical Field

[0001] This application relates to the field of molding equipment technology, and in particular to a wiring frame molding equipment. Background Technology

[0002] In the field of electronic component manufacturing, the junction box is a key component for circuit connection, and its structural integrity and dimensional accuracy directly affect the stability of the circuit connection. Currently, the molding and processing of junction boxes in the industry mostly adopts a step-by-step production mode, which requires multiple independent processes such as feeding, stamping, pre-forming, final forming, cutting, and unloading. The workpieces need to be transferred manually or by additional conveyor mechanisms between each process, which not only leads to a lengthy production process, but also increases the risk of workpiece collision and positioning deviation due to multiple transfers, ultimately affecting the product qualification rate and making it difficult to meet the dual requirements of efficiency and precision for large-scale production.

[0003] Existing molding equipment suffers from the following core problems: First, the molding process is fragmented. Most equipment requires separating pre-forming and final forming into different stations. When the workpiece is transferred between stations, positional shifts are likely to occur, especially for wiring frames with irregular structures such as side protrusions. The special shape of the pre-formed workpiece makes conventional material guiding structures unsuitable, easily leading to jamming or deformation. Second, the cutting mechanism and forming mechanism are set up independently. The cutting action needs to be precisely synchronized with the forming action. Existing equipment often uses multiple sets of drive devices for separate control, resulting in poor synchronization and problems such as cutting size deviations or incomplete forming. Moreover, the cutting blades are mostly fixed, making replacement cumbersome after wear, increasing equipment maintenance costs and downtime. Third, the final formed workpiece is often difficult to detach due to its tight adhesion to the forming mandrel. Existing unloading methods mostly rely on manual assistance or simple ejection structures, resulting in low unloading efficiency and easy scratches on the workpiece surface, further reducing product quality.

[0004] Furthermore, the existing equipment's drive systems mostly use multiple motors to drive each forming component separately. This not only results in complex structures and high energy consumption, but also leads to poor coordination between the driving components, making it difficult to unify the forming rhythm and limiting production efficiency. At the same time, some equipment lacks material guiding channels and precise limiting structures adapted to irregular pre-formed workpieces, making it prone to workpiece deviation during processing. This requires frequent manual adjustments, further increasing the difficulty of operation and labor costs.

[0005] To address the aforementioned technical challenges, there is an urgent need to develop a wiring frame molding equipment that is highly integrated, has high molding precision, is easy to operate, and has low maintenance costs. By optimizing process integration, improving the drive and material guiding structure, and perfecting the unloading mechanism, continuous and high-precision production of wiring frames from material feeding to finished product output can be achieved, meeting the industry's demand for efficient and high-quality production. Utility Model Content

[0006] In order to overcome the problems existing in the prior art, this application provides a wiring frame forming device.

[0007] The junction box forming equipment provided in this application adopts the following technical solution:

[0008] A wire frame forming device includes a feeding mechanism, a punching mechanism, and a forming mechanism arranged sequentially. The forming mechanism includes a first forming section and a second forming section. The first forming section is located at the outlet of the feeding section in the forming mechanism. A guide section is provided between the first forming section and the second forming section. The first forming section includes pre-forming rods located on the upper and lower sides of the strip, wherein the pre-forming rods move up and down longitudinally along the first forming section. The second forming section has a mandrel and forming rods circumferentially distributed around the mandrel. A cutting blade is provided near the outlet of the guide section on the forming rods, wherein the cutting blade is detachably connected to the forming rods. The feeding section has rectangular perforations adapted to the strip, and the guide section has irregular perforations adapted to the pre-formed strip.

[0009] Preferably, the forming rods are circumferentially distributed around the second forming section, including a first rod, a second rod, a third rod, a fourth rod, a fifth rod, and a sixth rod distributed clockwise along the mandrel. Limiting plates extending from the output end of the forming plate are installed on the outer sides of the third and fifth rods. A cutting blade is installed on the sixth rod near the discharge port of the guiding section. The cutting blade is detachably mounted on the side of the sixth rod, and the side of the cutting blade has a fixing protrusion adapted to the mounting groove on the sixth rod. The fixing protrusion is horizontally arranged on the side of the cutting blade, maintaining a stable connection with the sixth rod during longitudinal cutting, and the output end of the cutting blade protrudes beyond the output end of the sixth rod. The forming mechanism also includes a base plate, with the mandrel located at the center of the base plate, and unloading rods arranged circumferentially around the mandrel. The unloading rods are driven to move forward and backward within the base plate by a power mechanism on the back of the base plate, wherein the power mechanism is a cylinder or a hydraulic cylinder. A discharge frame is also installed on the base plate, with a discharge port corresponding to the mandrel at its center, and the bottom of the discharge port adopts an outward-facing guiding slope. After being pre-formed in the pre-forming section, the strip enters the forming section. After the strip enters above the mandrel and extends a short distance, the fifth rod at the top of the mandrel presses the strip against the upper surface of the mandrel. Then, the sixth rod cuts the strip required for a single wiring frame from the strip body through a detachable cutting blade. The sixth rod also shapes the strip on the side of the mandrel. The output end of the cutting blade, which is detachably connected to the sixth rod, protrudes beyond the output end of the sixth rod, ensuring that the strip is cut before bending and forming, thus avoiding errors in the cutting dimensions of a single wiring frame. After being bent, the strip is formed by the first and second rods in sequence. After the other end of the strip is formed by the fourth rod, the two free ends of the strip are connected by the third rod. During this process, the limiting plates installed on the outer side of the third and fifth rods can prevent the strip from shifting during the forming process, ensuring the forming accuracy and completing the forming operation of the wiring frame. Finally, all the forming rods of the forming part retract, and the power mechanism drives the unloading rods around the mandrel to unload the formed wiring frame from the unloading port of the discharge frame. The bottom of the unloading port leads the wiring frame out through the outward-facing slope.

[0010] Preferably, the preforming rod includes a seventh rod and an eighth rod disposed on the upper and lower sides of the first forming part. The seventh rod abuts against the top surface of the strip body, and the eighth rod is disposed at the bottom of the strip body. The output end of the eighth rod has an L-shaped structure corresponding to the side protrusion of the strip. The seventh rod presses the strip against the table surface of the preforming part, and the eighth rod, through the L-shaped structure at its output end, folds the side protrusion of the strip that needs to be longitudinally folded upward from the side of the strip body.

[0011] Preferably, both the preforming rod and the forming rod are driven by a drive mechanism, which is driven by a planetary gear array on the substrate. The planetary gears are driven by a sun gear inside the substrate, and the sun gear is driven by a planetary gear mounted on one side of the servo motor output. The drive mechanism includes a base and a drive plate slidably mounted on the base. An eccentric wheel is rotatably mounted on the base. A first fixing block and a second fixing block adapted to the eccentric wheel are mounted on the top of the drive plate. The eccentric wheel is driven by the planetary gears inside the substrate, and the planetary gears are transmitted to each other through the sun gear. The drive shaft of the eccentric wheel passes through a strip-shaped perforation on the drive plate. The eccentric wheel is in contact with the outer surface of the first fixing block around its perimeter. An actuating block capable of driving the second fixing block to move is also mounted on the bottom edge of the eccentric wheel. When the drive mechanism is working, the power is first transmitted to the sun gear in the base plate through the servo motor on the individual planetary gear. The sun gear drives the planetary gears that mesh with it to rotate. The planetary gears then drive the eccentric wheel connected to them to rotate synchronously on the base. As the eccentric wheel rotates, its circumference is always in contact with the outer surface of the first fixed block on the top of the drive plate. At the same time, the action block at the bottom edge of the eccentric wheel continuously contacts the second fixed block and drives it to move. Under the combined action of the limiting of the first fixed block and the driving of the action block on the second fixed block, the drive plate that is slidably mounted on the base is driven to slide stably along the base. The drive shaft of the eccentric wheel always moves adaptively with the sliding of the drive plate within the strip-shaped perforation on the drive plate. Finally, the sliding of the drive plate provides stable power to the forming rod, realizing the precise motion control of the forming rod in sequence.

[0012] Preferably, the feeding mechanism employs gear feeding, lead screw feeding, or swing arm feeding. Specifically, the gear feeding, lead screw feeding, or swing arm feeding utilizes the gear feeding structure in the automatic stamping and bending forming machine with gear feeding (CN221754382U), the lead screw feeding structure in the automatic stamping and bending forming machine with lead screw feeding (CN221773199U), and the swing arm feeding mechanism in the automatic stamping and bending forming machine (CN117983746A), respectively. The punching mechanism uses a die adapted to the wire frame to be formed for punching, including an upper die and a lower die. The lower die is fixed on the base of the punching mechanism. The upper die is driven by a hydraulic cylinder to punch the strip on the lower die. The punched-off waste material can be collected by falling into a collection box at the bottom of the lower die.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. This application integrates feeding, stamping, pre-forming of the first forming part, and final forming of the second forming part with cutting processes. With the matching design of rectangular perforation of the feeding part and irregular perforation of the guiding part, it realizes the forming of strip material in multiple directions. Moreover, the forming mechanism forms along the material fiber direction of the strip material during operation, which solves the problem of strip material being prone to breakage. At the same time, it avoids collisions and positioning deviations of the workpiece during transfer between multiple workstations, realizes the automatic forming of wiring frame with side protrusions, avoids material jamming and deformation problems, and improves structural integrity and dimensional accuracy.

[0015] 2. The cutting blade and forming rod of this application are detachable and can be installed separately. Combined with the unified drive mechanism driven by planetary gears and sun gears, it ensures precise synchronization of cutting and forming actions, reduces dimensional deviations, and the detachable cutting blade simplifies the wear and replacement process, reducing maintenance costs and downtime.

[0016] 3. In this application, the unloading bars around the core rod cooperate with the guide slope of the discharge frame to replace manual assistance and simple ejection structure, effectively solving the problem of difficult removal of the final formed workpiece, avoiding surface scratches, and improving product quality;

[0017] 4. The servo motor-driven planetary gear and sun gear coordinated system in this application replaces multiple motors driving separately, simplifies the equipment structure, reduces energy consumption, unifies the molding rhythm, and reduces manual adjustment by combining the precise positioning of the strip material with the limit plate. Ultimately, it realizes continuous and high-precision production of the wiring frame from feeding to finished product output, meeting the dual requirements of efficiency and precision for large-scale production.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a wiring frame forming device.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A wire frame forming device includes a feeding mechanism, a punching mechanism, and a forming mechanism 1 arranged in sequence. The forming mechanism 1 includes a first forming part 2 and a second forming part 3. The first forming part 2 is located at the outlet of the feeding part 4 in the forming mechanism 1. A guide part 5 is provided between the first forming part 2 and the second forming part 3. The first forming part 2 includes pre-forming rods 21 located on the upper and lower sides of the strip. The pre-forming rods 21 move up and down longitudinally along the first forming part 2. The second forming part 3 is provided with a core rod 31 and forming rods 32 circumferentially distributed around the core rod 31. A cutting blade 33 is provided near the outlet of the guide part 5 of the forming rods 32. The cutting blade 33 is detachably connected to the forming rods 32. The feeding part 4 has rectangular perforations 41 adapted to the strip. The guide part 5 has irregular perforations 51 adapted to the pre-formed strip.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The forming rods 32 are circumferentially distributed around the second forming section 3, including a first rod 321, a second rod 322, a third rod 323, a fourth rod 324, a fifth rod 325, and a sixth rod 326 distributed clockwise along the mandrel 31. Limiting plates 34 extending from the output end of the forming plate are installed on the outer sides of the third rod 323 and the fifth rod 325. A cutting blade 33 is installed on the sixth rod 326 near the discharge port of the guide section 5. The cutting blade 33 is detachably installed on the side of the sixth rod 326. The side of the cutting blade 33 has a fixing protrusion 331 that matches the mounting groove on the sixth rod 326. The fixing protrusion 331 is horizontally arranged on the side of the cutting blade 33, maintaining a stable connection with the sixth rod 326 during longitudinal cutting. The output end of the cutting blade 33 protrudes beyond the output end of the sixth rod 326. The molding mechanism 1 also includes a substrate 11, a mandrel 31 located at the center of the substrate 11, and unloading bars 12 arranged in a circular array around the mandrel 31. The unloading bars 12 are driven to move forward and backward within the substrate 11 by a power mechanism on the back of the substrate 11, wherein the power mechanism is a cylinder or a hydraulic cylinder. A discharge frame 111 is also installed on the substrate 11, wherein the center of the discharge frame 111 is provided with a discharge port 112 corresponding to the mandrel 31, and the bottom of the discharge port 112 adopts an outwardly facing guide slope 113. After being pre-formed in the pre-forming section, the strip enters the forming section. After the strip enters above the mandrel 31 and extends a short distance, the fifth rod 325 at the top of the mandrel 31 presses the strip against the upper surface of the mandrel 31. Then, the sixth rod 326 cuts the strip required for a single wiring frame from the strip body through the detachably mounted cutting blade 33. The sixth rod 326 also shapes the strip on the side of the mandrel 31. The output end of the cutting blade 33, which is detachably connected to the sixth rod 326, protrudes beyond the output end of the sixth rod 326, ensuring that the strip is cut before bending and forming, thus avoiding errors in the cutting dimensions of a single wiring frame. After bending, the strip is formed by the first rod 321 and the second rod 322. The other end of the strip is formed by the fourth rod 324. Then, the two free ends of the strip are connected by the third rod 323. During this process, the limiting plate 34 installed on the outer side of the third rod 323 and the fifth rod can prevent the strip from shifting during the forming process, ensuring the forming accuracy and completing the forming operation of the wiring frame. Finally, all the forming rods 32 of the forming part retract, and the power mechanism drives the unloading rods 12 around the core rod 31 to unload the formed wiring frame on the core rod 31 from the unloading port 112 of the discharge frame 111. The bottom of the unloading port 112 leads the wiring frame out through the outward inclined surface.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The preforming rod 21 includes a seventh rod 211 and an eighth rod 212 disposed on the upper and lower sides of the first forming part 2. The seventh rod 211 abuts against the top surface of the strip body, and the eighth rod 212 is disposed at the bottom of the strip body. The output end of the eighth rod 212 has an L-shaped structure corresponding to the side protrusion of the strip. The seventh rod 211 presses the strip against the table surface of the preforming part, and the eighth rod 212 folds the side protrusion of the strip body that needs to be folded longitudinally upward from the side of the strip body through the L-shaped structure at its output end.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Both the preforming rod 21 and the forming rod 32 are driven by the driving mechanism 6, which is driven by a planetary gear array on the substrate 11. The planetary gears are driven by a sun gear inside the substrate 11, and the sun gear is driven by a planetary gear mounted on one side of the servo motor output end. The driving mechanism 6 includes a base 61 and a driving plate 62 slidably mounted on the base 61. An eccentric wheel 611 is rotatably mounted on the base 61. A first fixing block 621 and a second fixing block 622 adapted to the eccentric wheel 611 are mounted on the top of the driving plate 62. The eccentric wheel 611 is driven by the planetary gears inside the substrate 11, and the planetary gears are transmitted to each other through the sun gear. The driving shaft of the eccentric wheel 611 passes through a strip-shaped perforation on the driving plate 62. The periphery of the eccentric wheel 611 is in contact with the outer surface of the first fixing block 621. An actuating block capable of driving the second fixing block 622 to move is also mounted on the bottom edge of the eccentric wheel 611. When the drive mechanism 6 is working, the power is first driven by the servo motor on a single planetary gear, and the power is first transmitted to the sun gear in the base plate 11. The sun gear drives the planetary gears that mesh with it to rotate. The planetary gears then drive the eccentric wheel 611 connected to it to rotate synchronously on the base 61. As the eccentric wheel 611 rotates, its circumference is always in contact with the outer surface of the first fixing block 621 on the top of the drive plate 62. At the same time, the action block at the bottom edge of the eccentric wheel 611 continuously contacts the second fixing block 622 and drives it to move. Under the combined action of the limiting of the first fixing block 621 and the driving of the action block on the second fixing block 622, the drive plate 62, which is slidably mounted on the base 61, is driven to slide stably along the base 61. The drive shaft of the eccentric wheel 611 always moves adaptively with the drive plate 62 as it slides within the strip-shaped perforation on the drive plate 62. Finally, the sliding of the drive plate 62 provides stable power to the forming rod 32, realizing the precise motion control of the forming rod 32.

[0030] The feeding mechanism employs gear feeding, lead screw feeding, or swing arm feeding, specifically utilizing the gear feeding structure in our corresponding patents CN221754382U (an automatic stamping and bending forming machine with gear feeding), CN221773199U (an automatic stamping and bending forming machine with lead screw feeding), and CN117983746A (an automatic stamping and bending forming machine), respectively. The punching mechanism uses a die adapted to the wire frame to be formed, including an upper die and a lower die. The lower die is fixed to the base of the punching mechanism. The upper die is driven by a hydraulic cylinder to punch the strip on the lower die. Waste material from punching can be collected by a collection box at the bottom of the lower die.

[0031] Working principle: First, the feeding mechanism conveys the strip to the punching mechanism for preliminary processing, punching the strip into the shape of the required wiring frame. Then, the strip enters the feeding part 4 of the forming mechanism 1. The rectangular through hole 41 of the feeding part 4 initially limits the strip. After the strip is output from the feeding part 4, it enters the first forming part 2. The seventh rod 211, which is distributed vertically, abuts against the top surface of the strip. The L-shaped structure at the output end of the eighth rod 212 adapts to the side protrusion of the strip. The strip moves up and down along the first forming part 2 to complete the pre-forming. After being pre-formed in the pre-forming section, the strip enters the forming section. After extending slightly above the mandrel 31, the fifth rod 325 at the top of the mandrel 31 presses the strip against the upper surface of the mandrel 31. Then, the sixth rod 326, through a detachably mounted cutting blade 33, cuts the strip required for a single wiring frame from the strip body. The sixth rod 326 then bends the strip on the side of the mandrel 31. The bent strip then passes through the first rod 321 and the second rod 322 for forming, and the other end of the strip passes through the fourth rod 324. After the forming process, the two free ends of the strip are connected by the third rod 323. During this process, the limiting plate 34 installed on the outer side of the third rod 323 and the fifth rod can prevent the strip from shifting during the forming process, ensuring forming accuracy and completing the forming operation of the wiring frame. Finally, all the forming rods 32 of the forming part retract, and the power mechanism drives the unloading rods 12 around the mandrel 31 to unload the formed wiring frame on the mandrel 31 from the unloading port 112 of the discharge frame 111. The bottom of the unloading port 112 leads the wiring frame out through the outward-facing inclined surface. Throughout the process, the driving of the pre-forming rod 21 and the forming rod 32 depends on the sun gear in the base plate 11 driving the planetary gear, and then the planetary gear drives the eccentric wheel 611 and other structures to achieve coordinated action of each component, ensuring forming accuracy and efficiency. At the same time, the detachable cutting blade 33 and the special material guiding and unloading structure reduce maintenance costs and the risk of workpiece damage.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
