Description

Technical Field

[0001] This invention relates to the field of copper lead straightening technology, and more particularly to a lead straightening device. Background Technology

[0002] Copper leads have excellent electrical and thermal conductivity, making them one of the core components for achieving electrical connections and signal transmission in products. Therefore, products with copper leads are widely used in many fields such as electronic components, motor windings, and connectors.

[0003] However, during the production, transportation, and storage of copper lead products, the copper leads themselves are relatively soft and easily affected by external forces such as compression and collisions. This can lead to deformation problems such as bending, twisting, and warping. Irregular deformation of the copper leads can severely interfere with subsequent processes. To solve this problem and ensure product quality, existing technologies typically require straightening bent copper leads. Currently, most copper lead straightening operations in the industry rely on manual labor, using simple tools such as tweezers and pliers to manually straighten and shape the copper leads. This method results in low straightening efficiency and a highly subjective and random straightening effect, making it difficult to fundamentally guarantee the regularity of the copper lead's shape, thus negatively impacting the consistency of product quality.

[0004] Therefore, a lead wire straightening device is proposed to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

[0009] Preferably, grooves are provided at the ends of the inner grippers of both the second and third pneumatic grippers.

[0010] Preferably, the conveyor line includes a vertically fixed ring rail installed inside the machine base, with synchronous pulleys rotatably installed at the center positions of both ends of the ring rail.

A vertically arranged support plate is fixedly installed on the slide block, and a positioning groove is opened at the outer end of the support plate.

[0011] Preferably, multiple equally spaced locking blocks are fixedly installed on the outer side of the timing belt, and the multiple locking blocks are correspondingly set with multiple slides. First column rods clamping the two sides of the locking blocks are fixedly installed on the slides, and the slides are connected to the timing belt through the cooperation of the locking blocks and the first column rods.

[0012] Preferably, a locking pin is fixedly installed on the slide block, and a second pneumatic push rod is fixedly installed inside the machine tool below each workstation, and a slot that matches the locking pin is fixedly installed on the piston rod of the second pneumatic push rod.

[0013] Preferably, the aperture shaping assembly further includes a ring plate rotatably mounted within the frame, with multiple circularly distributed linear guides fixedly mounted on the ring plate, multiple clamping blocks slidably connected to the multiple linear guides, and second column rods fixedly mounted on the clamping blocks.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting up an automated feeding mechanism, a circular conveyor line, and a multi-station collaborative shaping mechanism, fully automated straightening of copper leads can be achieved, which is beneficial to significantly improving the straightening efficiency of copper leads. At the same time, pre-straightening is performed by a second pneumatic gripper, and then multiple servo shaping components and aperture shaping components work together. The servo shaping components can mimic manual straightening actions to perform precise axial stretching and straightening of the leads, while the aperture shaping components perform comprehensive micro-shaping and shaping of the leads through the synchronous radial contraction and rotational kneading of multiple clamping blocks. With their cooperation, the high consistency and regularity of the product lead straightening effect can be effectively improved, which is beneficial to improving the overall quality of the product. 2. In this invention, the cooperation of the locking pin and the locking groove can effectively ensure the positioning accuracy of the copper leads of the product being straightened and corrected at different work stations on the conveyor line. At the same time, the restriction of the pressure plate inside the limiting mechanism can prevent the product from falling off during the conveying process. With the downward driving of the roller, the product flipping can be precisely controlled at different work stations, which is conducive to achieving multi-angle cross-shaping, thereby further improving the quality of the product after the copper leads are straightened and shaped.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example: This example provides a lead wire straightening device, see [link to example]. Figure 1 - Figure 16 Specifically, the system includes a machine base 1, a feeding mechanism installed inside the machine base 1, a conveyor line 3 installed in the middle of the machine base 1, a vibration component 2 fixedly installed inside the machine base 1, a vision module 21 fixedly installed above the vibration component 2 inside the machine base 1, a four-axis robot 22 fixedly installed inside the machine base 1 between the vibration component 2 and the conveyor line 3, and a robotic arm fixture 23 fixedly installed at the end of the four-axis robot 22, a first pneumatic gripper 231 fixedly installed on the robotic arm fixture 23, second pneumatic grippers 232 symmetrically arranged on both sides of the first pneumatic gripper 231, and a first pneumatic push rod 233 for driving the two second pneumatic grippers 232 to move synchronously relative to each other, and a groove 6 is provided at the end of the gripper in the second pneumatic gripper 232.

[0021] Vibration component 2 consists of a vibration chamber and a vibrating plate. The vibrating plate is composed of a hopper body and a planar vibrator. The hopper body adopts an open, large-capacity design, which can store a certain batch of bulk products. During processing, the products to be straightened copper leads are placed on the vibration chamber and fall onto the vibrating plate in an orderly manner through the vibration of the hopper. The bottom of the hopper body is equipped with an electromagnetic vibrator, which uses high-frequency micro-amplitude vibration to arrange the products in an orderly manner along the spiral track on the inner wall of the hopper body. Finally, the products are accurately transported to the designated position via a linear feeding track to meet the gripping needs of the robotic arm.

[0022] The vision module 21 is positioned directly above the vibratory feeder. The camera within the vision module 21 collects and uploads the product's feature data. The vision module 21 employs a cantilevered, adjustable mounting structure, fixed to the machine base 1 via a crossbar and frame. It supports horizontal and vertical position adjustment, flexibly adapting to the working area of ​​the four-axis robot 22. The vision module 21 integrates an industrial camera, lens, and light source, featuring a dustproof encapsulation design with an IP54 protection rating, effectively adapting to complex industrial environments. The industrial camera is equipped with a high-resolution CMOS sensor and a fixed-focus lens, achieving a detection accuracy of ≥0.02mm. This effectively enables coordinate positioning, dimensional measurement, and appearance defect identification of products on the vibratory feeder. Furthermore, the ring light source positioned below features adjustable brightness, adapting to the lighting needs of products made of different materials, effectively improving the stability and accuracy of visual recognition.

[0023] In addition, the vision module 21 also has a built-in data transmission interface, which can interact with the equipment control system in real time to obtain detection results. This facilitates closed-loop control that combines visual guidance with anomaly interception. The vision module 21 supports software parameter debugging, and parameters such as exposure time and gain can be flexibly adjusted to adapt to the detection needs of materials of different colors and sizes. At the same time, it has reserved expansion interfaces, which can add functions such as barcode reading and QR code recognition according to the scenario, effectively improving the intelligent detection capability of the equipment and improving the detection accuracy of copper wires before straightening to a certain extent.

[0024] After detection and identification, the four-axis robot 22 inside the device controls the robotic arm fixture 23 to move onto the vibratory feeder. Based on visual signals, it uses the first pneumatic gripper 231 to precisely grasp the product. During this process, the first pneumatic gripper 231 clamps the main body of the product, ensuring a precise fit with the product's shape and stable gripping. The first pneumatic gripper 231 can flexibly adjust the clamping force, and in conjunction with the built-in position detection sensor, it can provide real-time feedback on the gripping status, facilitating communication with the four-axis robot 22 and the transport... The feeder 3 enables signal linkage. The main body of the first pneumatic gripper 231 is made of hard aluminum alloy with an anodized surface, which combines lightweight and wear resistance, and meets the industrial site protection requirements of the equipment. In addition, the gripping stroke and gripper spacing of the first pneumatic gripper 231 can be adjusted slightly, so that it can be adapted to gripping operations of multiple specifications of the same series of products. At the same time, the robotic arm fixture 23 has a quick-change interface, which facilitates the quick replacement of different types of first pneumatic grippers 231 according to production needs, which can effectively improve the flexible production capacity of the device.

[0025] After the product is gripped and grasped, the second pneumatic gripper 232 is positioned to grip the roots of the copper leads on both sides of the product body. The roots of the copper leads are positioned in the corresponding grooves 6. During the transfer of the product, the device controls the first pneumatic push rod 233 to move, causing the second pneumatic grippers 232, which are symmetrically arranged on both sides, to move away from each other simultaneously, performing the first straightening and shaping action on the copper leads of the product. Subsequently, the product is placed on the conveyor line 3 for circular conveying. This pre-straightening process can initially eliminate the large-scale bending deformation of the copper leads caused by transfer and storage, laying a good foundation for the fine shaping of subsequent workstations.

[0026] In the specific implementation process, such as Figure 1 and Figure 2As shown, there are two feeding mechanisms, which are symmetrically arranged on both sides of the feed end of the conveyor line 3. The two feeding mechanisms can form a parallel double feeding channel. Two four-axis robots 22 alternately grab products from their respective vibratory feeders and place them in the front end of the conveyor line 3 for subsequent conveying. This can increase the feeding cycle of the equipment by nearly 100%, effectively improving the overall efficiency of the entire production line.

[0027] In the specific implementation process, such as Figure 2 and Figure 15 - Figure 16 As shown, six workstations are arranged sequentially along the conveyor line 3 inside the machine base 1. The conveyor line 3 includes a vertically fixed ring rail 31 installed inside the machine base 1, and synchronous pulleys 32 are rotatably installed at the center positions of both ends of the ring rail 31. A synchronous belt 33 is driven and sleeved on the two synchronous pulleys 32. A first servo motor 34 for driving the synchronous pulleys 32 to rotate is fixedly installed inside the ring rail 31. Multiple equally spaced slide blocks 35 are slidably installed on the ring rail 31. The distance between two adjacent slide blocks 35 is the same as the distance between two adjacent workstations. A vertically arranged support plate 36 is fixedly installed on the slide block 35, and a positioning groove 37 is opened at the outer end of the support plate 36. Multiple equally spaced clamping blocks 38 are fixedly installed on the outer side of the synchronous belt 33. The multiple clamping blocks 38 are correspondingly arranged with the multiple slide blocks 35. A first column rod 39 clamping both sides of the clamping block 38 is fixedly installed on the slide block 35. The slide block 35 is connected to the synchronous belt 33 through the cooperation of the clamping block 38 and the first column rod 39.

[0028] During the operation of conveyor line 3, the first servo motor 34 drives the synchronous wheel 32 to rotate, which in turn drives the synchronous belt 33 to move intermittently. Through the engagement of the locking block 38 and the first column rod 39, the corresponding slide block 35 and the bearing plate 36 are driven to move synchronously along the ring rail 31, thereby realizing the precise stepping conveying of the product between the six workstations. The positioning groove 37 on the bearing plate 36 is used to accommodate and initially limit the main body of the product. The copper wires of the product protrude from both sides of the positioning groove 37.

[0029] In the specific implementation process, such as Figure 5 and Figure 16As shown, a locking pin 310 is fixedly installed on the slide 35, and a second pneumatic push rod 311 is fixedly installed inside the machine base 1, located below each workstation. A slot 312 adapted to the locking pin 310 is fixedly installed on the piston rod of the second pneumatic push rod 311. When the carrier plate 36 moves the product in its internal positioning slot 37 to the corresponding workstation, before straightening and shaping the copper wire of the product, the second pneumatic push rod 311 is controlled to move, causing the slot 312 to engage with the locking pin 310, thus positioning the slide 35. This ensures that the product in the positioning slot 37 on the carrier plate 36 is in a stable position before straightening and shaping, thereby improving processing stability. After the product shaping and processing is completed at each workstation, the second pneumatic push rod 311 will retract and reset, automatically releasing the lock on the slide 35.

[0030] In the specific implementation process, such as Figure 10 - Figure 12 As shown, a shaping mechanism 4 is installed inside the machine tool 1. The shaping mechanism 4 includes four sets of servo shaping components 41 and two sets of aperture shaping components 42. The four sets of servo shaping components 41 are installed sequentially on the first four workstations, and the two sets of aperture shaping components 42 are installed sequentially on the last two workstations. Each set of servo shaping components 41 includes two third pneumatic grippers 411 symmetrically arranged on both sides of the conveyor line 3, and a first electric slide 412 that drives the two third pneumatic grippers 411 to move synchronously relative to each other. The end of the gripper in the third pneumatic gripper 411 is also provided with a groove 6.

[0031] Once the product reaches and is positioned at the corresponding station of the servo shaping component 41, the third pneumatic grippers 411 on both sides, guided by the corresponding grooves 6, precisely clamp the root positions of the copper leads on both sides of the product. Subsequently, the first electric slide 412 drives the two third pneumatic grippers 411 to perform one or more synchronous back-to-back movements, mimicking manual straightening actions, applying horizontal tensile force to the copper leads, effectively correcting their axial straightness. This operation can be performed continuously at multiple stations, gradually achieving the best straightening effect.

[0032] In the specific implementation process, such as Figure 10 and Figure 13 - Figure 14As shown, each aperture shaping assembly 42 includes two frames 421 symmetrically arranged on both sides of the conveyor line 3, and a second electric slide 422 that drives the two frames 421 to move synchronously relative to each other. Multiple synchronously moving clamps 425 are installed around the frame 421, and the ends of the clamps 425 are set as triangular structures. The aperture shaping assembly 42 also includes an annular plate 423 rotatably installed inside the frame 421. Multiple circularly distributed linear rails 424 are fixedly installed on the annular plate 423. Multiple clamps 425 are slidably connected to multiple linear rails 424. Second columns 426 are fixedly installed on the clamps 425. Multiple circularly distributed arc-shaped through slots 427 are opened on the frame 421. Multiple second columns 426 are movably inserted into multiple arc-shaped through slots 427. A second servo motor 428 for driving the rotation of the annular plate 423 is fixedly installed on the frame 421.

[0033] During operation, the second electric slide 422 first drives the two frames 421 to move towards each other, so that the triangular ends of all the clamping blocks 425 surround the root of the copper lead to be shaped. Then, the second servo motor 428 drives the ring plate 423 to rotate alternately in both directions. The rotation of the ring plate 423 drives the clamping blocks 425 to move radially through the linear guide 424 on it. Meanwhile, the sliding trajectory of the second column 426 in the arc-shaped through groove 427 converts the circular motion into the linear reciprocating motion of the clamping blocks 425 along the linear guide 424. Ultimately, all the clamps 425, driven by the second servo motor 428, synchronously and periodically retract and open radially. In conjunction with the movement of the control frame 421 by the second electric slide 422, the surface of the lead wire is rotated and rubbed. Through this ring-shaped retraction action, the lead wire can be evenly forceped in 360°. It is especially suitable for correcting the twisting, warping and irregular local bending of the lead wire, so that the copper lead wire of the product can achieve a fine shaping effect after correction and straightening.

[0034] In the specific implementation process, such as Figure 2 - Figure 6 As shown, a limiting mechanism 5 spanning six workstations is installed above the conveyor line 3. The limiting mechanism 5 includes a bracket 51 fixedly connected to the machine base 1. A vertically arranged pressure plate 52 is fixedly installed inside the bracket 51, and the bottom of the pressure plate 52 slides against the top of the upper bearing plate 36. A vertical frame 53 is slidably connected inside the pressure plate 52. A third pneumatic push rod 54 for driving the vertical frame 53 to lift and adjust is fixedly installed on the bracket 51. Rollers 55 located in each workstation are rotatably installed at the bottom of the vertical frame 53. A gear 56 is rotatably installed on the vertical frame 53, and a toothed rod 57 is meshed with the outer side of the gear 56. A fourth pneumatic push rod 58 for driving the toothed rod 57 to move is fixedly installed on the vertical frame 53. A belt drive assembly 59 is connected between the gear 56 and the multiple rollers 55. Two symmetrically arranged rollers 510 are rotatably installed in the positioning groove 37.

[0035] By blocking the pressure plate 52, the product can be prevented from falling out of the positioning groove 37 during the conveying process of the conveyor line 3. When the product is transferred from one station to the next, the roller 55 can drive the product to rotate 90° in the positioning groove 37, change its posture when it is straightened again, and improve the straightening and shaping effect.

[0036] Specifically, within the limiting mechanism 5, the fourth pneumatic push rod 58 can drive the rack 57 to move, thereby driving the gear 56 meshing with it to rotate. Under the transmission connection of the belt drive assembly 59, the rotation of the gear 56 can be synchronously transmitted to all the rollers 55 above the corresponding workstation. After the bearing plate 36 carries the product from one shaping workstation to the next, the third pneumatic push rod 54 can drive the vertical frame 53 to descend, so that the rollers 55 are pressed against the top of the product. Then the gear 56 rotates and drives the rollers 55 to rotate, using friction to drive the product to rotate precisely 90° in the positioning groove 37. This design allows the product to be flipped after each horizontal straightening when it is shaped by the first four sets of servo shaping assemblies 41, thereby ensuring that the next servo shaping can apply force again from the direction perpendicular to the previous one, realizing cross-correction in two dimensions, which can effectively improve the comprehensiveness and accuracy of copper lead straightening.

[0037] Specifically, the working principle of this invention is as follows: First, the product to be processed is poured into the vibration chamber of two symmetrically arranged vibration components 2. After the product is sorted by vibration, it is transported to the designated position of the vibratory plate. The vision module 21 above takes a picture of the product to identify its position and posture, and sends the coordinate information to the four-axis robot 22. The four-axis robot 22 drives the robotic arm fixture 23 to move to the gripping point. The first pneumatic gripper 231 clamps the main body of the product, and the second pneumatic grippers 232 on both sides hold the root of the copper lead wire under the guidance of the groove 6. Then, the first pneumatic push rod 233 moves to drive the two second pneumatic grippers 232 to move in opposite directions to perform the first pre-stretching and straightening of the copper lead wire. The pre-stretched product is placed in the positioning groove 37 of the unloaded bearing plate 36 at the front end of the conveyor line 3.

[0038] The first servo motor 34 drives the synchronous belt 33 to perform intermittent motion, which drives all slides 35 and bearing plates 36 to move forward in steps. When the bearing plate 36 reaches a certain station, the second pneumatic push rod 311 below it is activated. Through the cooperation of the slot 312 and the pin 310, the slide 35 is firmly locked at the station to ensure processing stability.

[0039] The product passes through the first four sets of servo shaping components 41 in sequence. At the corresponding workstation, the third pneumatic grippers 411 on both sides hold the root of the lead wire and are driven by the first electric slide 412 to straighten it horizontally. Before each stepping movement to the next servo shaping workstation, the rollers 55 in the limit mechanism 5 will rotate the product 90° according to the instruction to achieve cross-shaping in different directions.

[0040] Subsequently, the product enters the last two sets of aperture shaping components 42. At this station, multiple clamps 425 on the two side frames 421 close and surround the root of the lead wire from all sides, and are driven by the second servo motor 428 to perform synchronous radial reciprocating motion of closing and opening, applying rotational kneading to the copper lead wire, and performing all-round fine shaping and shaping of the lead wire.

[0041] After all six workstations have completed the shaping process, the products are conveyed by conveyor line 3 to the unloading area for automatic unloading.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
