Description

Technical Field

[0001] This application relates to the field of coil processing equipment, and in particular to a coil winding and bending production line. Background Technology

[0002] Currently, coils are widely used as key components in various electronic devices in the electronics manufacturing industry. With the increasing miniaturization and complexity of electronic products, the production requirements for coils are also becoming more stringent, demanding not only high production efficiency but also stable product quality and high pin bending precision. Therefore, the level of automation in coil production lines has become an important indicator of coil manufacturing capability.

[0003] Currently, the production process of coils largely relies on manual operation, especially in the two key steps of winding and bending. The traditional production process involves manual coil handling, followed by manual operation of individual station-based machines to complete the subsequent processes. This approach has many problems, such as low production efficiency due to dispersed processes, significant resource consumption during connection, easy damage to coils during circulation, poor coordination between equipment, and difficulty in real-time tracking of production data. These problems collectively lead to low production efficiency and large quality fluctuations.

[0004] The process flow in the relevant technology has the following defects: First, manual operation leads to low production efficiency and cannot meet the needs of large-scale production; second, due to the dispersed process and the loose connection between equipment, resources are wasted; third, the coil is easily damaged by human factors during the circulation process, which affects the quality of the product. Utility Model Content

[0005] To address the aforementioned issues, improve the automation and efficiency of coil production, and ensure product quality and traceability of production data, this application provides a coil winding and bending production line.

[0006] The coil winding and bending production line provided in this application adopts the following technical solution:

[0007] A coil winding and bending production line includes a picking device, a rotary feeding device, a bending device, and a unloading device. The picking device is used to transport the coil to the rotary feeding device, which drives the coil to make a circular motion to convey the coil to the bending device. The bending device is used to bend the coil leads. The rotary feeding device is used to convey the coil to the unloading device, which is used to convey the coil to the receiving device. The receiving device is used to hold multiple formed coils.

[0008] By adopting the above technical solution, the entire production line achieves fully automated processing of coils from picking up, conveying, bending to unloading through the close cooperation and seamless connection of the material handling device, rotary feeding device, bending device, and unloading device. The rotary feeding device efficiently conveys the coils to each workstation in a circular motion, ensuring the continuity and stability of the production process; the bending device ensures the accuracy and consistency of coil lead bending through precise clamping and bending actions; the close cooperation of all parts of the entire production line achieves seamless connection, thereby greatly improving the process changeover speed and overall equipment stability; it not only reduces production space occupation and lowers safety risks, but also improves process changeover speed and overall equipment stability, ensuring precise control during production and high-reliability product output.

[0009] Optionally, the rotary feeding device includes a turntable and a rotary drive mechanism, the rotary drive mechanism being used to drive the turntable to rotate; the turntable is provided with a plurality of positioning seats along the circumference, each of the positioning seats having a positioning groove for positioning the coil, the shape of the positioning groove being adapted to the shape of the coil.

[0010] By adopting the above technical solution, the rotary drive mechanism drives the turntable to rotate, and multiple positioning seats arranged circumferentially on the turntable rotate accordingly. The positioning groove on each positioning seat can accurately and stably position the coil. Since the shape of the positioning groove matches the shape of the coil, the stability and accuracy of the coil during the feeding process are ensured, thereby improving production efficiency and product quality.

[0011] Optionally, the bending device includes a first clamping mechanism and a second clamping mechanism. When the turntable is in a stopped state, at least one positioning seat is located between the first clamping mechanism and the second clamping mechanism. The first clamping mechanism and the second clamping mechanism are respectively used to clamp the pins on both sides of the coil.

[0012] By adopting the above technical solution, when the turntable stops rotating at a specific position, a positioning seat is precisely positioned between the first clamping mechanism and the second clamping mechanism each time. At this time, the first clamping mechanism and the second clamping mechanism respectively clamp the pins on both sides of the coil, realizing a precise bending operation on the coil pins. This not only improves the automation level of coil pin bending but also ensures the accuracy and consistency of the bending position, thereby further improving production efficiency and product quality.

[0013] Optionally, the first clamping mechanism includes a lifting drive assembly and a plurality of first clamping assemblies, each of which corresponds to a positioning seat and is disposed on the positioning seat. The lifting drive assembly is used to drive the first clamping assemblies to work.

[0014] By adopting the above technical solution, the lifting drive assembly can precisely control the lifting movement of multiple first clamping components, each corresponding to a positioning seat. When the turntable rotates to a specific position and the positioning seat is located between the first and second clamping mechanisms, the corresponding first clamping component descends under the drive of the lifting drive assembly and clamps the coil pin, achieving stable clamping of the coil pin before bending. This not only improves the accuracy and stability of clamping but also ensures the smooth execution of the bending operation, further enhancing the automation and efficiency of the entire production line.

[0015] Optionally, the first clamping assembly includes a mounting base, a clamping component, and a lifting base. The mounting base is disposed on the positioning base. The clamping component includes two first clamping parts, which are rotatably connected to the mounting base. The two first clamping parts are used to clamp two pins on one side of the coil. The lifting base is slidably engaged with the positioning base. During the lifting process, the lifting base is used to simultaneously drive the two first clamping parts to rotate. The lifting drive assembly is used to drive the lifting base to lift.

[0016] By adopting the above technical solution, the lifting drive assembly drives the lifting seat to slide and rise on the positioning seat, thereby causing the two first clamping parts, which are rotatably connected to the mounting seat, to rotate synchronously, achieving stable clamping of the two pins on one side of the coil. This not only ensures the accuracy and stability of the clamping action, but also improves the clamping efficiency through the combined action of lifting and rotation, enabling the coil pins to be quickly and accurately positioned and clamped, providing strong support for subsequent bending operations, and further improving the automation, accuracy, and production efficiency of the entire production line.

[0017] Optionally, the lifting drive assembly includes a first support, a first lifting drive component, and a lifting block. The first lifting drive component is disposed on the first support and is used to drive the lifting block to move up and down.

[0018] By adopting the above technical solution, the first lifting drive component is mounted on the first support. By driving the lifting block to rise and fall, it in turn drives the first clamping component connected to the lifting block to move up and down, thereby achieving the clamping and release of the coil pin. The structure is compact and the operation is reliable. It can precisely control the lifting height and speed of the first clamping component, ensuring the stability and accuracy of the coil pin during bending, and further improving the automation level and production efficiency of the entire coil processing flow.

[0019] Optionally, the second clamping mechanism includes a lateral movement component, a pressing component, and a straightening and bending component. The lateral movement component is used to drive the pressing component and the straightening and bending component to move in the horizontal direction. The pressing component is used to fix the coil on the positioning seat. The straightening and bending component is used to straighten the coil leads first and then bend them.

[0020] By adopting the above technical solution, the lateral movement component of the second clamping mechanism can flexibly adjust the positions of the pressing component and the straightening and bending component, ensuring that they can accurately align with the corresponding parts of the coil. The pressing component, through precise horizontal and vertical driving, can firmly fix the coil, preventing displacement or deformation during bending. The straightening and bending component, through horizontal movement and rotation, can first straighten the coil leads before precisely bending them, ensuring that the lead shape meets processing requirements and improving product quality and consistency.

[0021] Optionally, the pressing assembly includes a first horizontal drive, a second lifting drive, and a pressing component. The first horizontal drive is disposed on a transverse base. The first horizontal drive is used to drive the second lifting drive to move in the horizontal direction. The second lifting drive is used to drive the pressing component to move up and down to press the coil on the fixed positioning base.

[0022] By adopting the above technical solution, the lateral movement component can drive the pressing component and the straightening and bending component to move precisely horizontally above the positioning seat. The pressing component first fixes the coil on the positioning seat, and then the straightening and bending component straightens and bends the coil leads. This not only ensures the precise positioning and fixation of the coil leads before bending, but also improves the quality and consistency of lead bending through the continuous action of straightening and bending, further enhancing the automation, stability, and production efficiency of the entire coil processing flow.

[0023] Optionally, the straightening and bending assembly includes a sliding member, a second horizontal driving member, a rotary driving member, a rotary member, and a second clamping assembly. The sliding member slides in conjunction with the horizontal moving assembly. The second horizontal driving member drives the sliding member to move horizontally, and the moving direction of the sliding member is perpendicular to the moving direction of the horizontal moving assembly. The rotary driving member is disposed on the sliding member and drives the rotary member to rotate. The second clamping assembly is disposed on the rotary member and clamps two pins on the other side of the coil.

[0024] By adopting the above technical solution, the second horizontal drive component drives the sliding component to move in a horizontal direction perpendicular to the moving direction of the transverse base, enabling the rotating component and its second clamping assembly to accurately reach the position of the coil pins. Subsequently, the rotation drive component drives the rotating component to rotate, causing the second clamping assembly to clamp the two pins on the other side of the coil and straighten them. After straightening, the pins are bent through further rotation or in conjunction with other mechanisms. This not only achieves continuous automated processing of the pins from pulling to bending, but also ensures the accuracy and consistency of pin bending through precise movement and rotation control, greatly improving the efficiency and quality of coil processing.

[0025] Optionally, the second clamping assembly includes a gripper cylinder and two second clamping parts, the two second clamping parts being rotatably mounted on the rotating member; the gripper cylinder is mounted on the rotating member and is used to drive the two second clamping parts to rotate, so as to clamp the two pins on the other side of the fixed coil.

[0026] By adopting the above technical solution, the gripper cylinder is mounted on the rotating component. By driving the two second gripping parts to rotate, it achieves stable gripping and fixing of the two pins on the other side of the coil. This not only simplifies the structure of the gripping mechanism and improves the reliability and accuracy of the gripping action, but also allows the second gripping components to flexibly cooperate with the rotating component to perform rotational operations, thus successfully completing the tasks of straightening and bending the pins. This improves the efficiency, stability, and product quality of coil processing.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the coordinated operation of the material picking device, rotary feeding device, bending device and unloading device, the entire process of coil picking, bending and unloading is automated, which significantly improves production efficiency, reduces manual intervention and avoids damage to coils during the circulation process;

[0029] 2. The rotary feeding device uses a turntable and multiple positioning seats to ensure the precise positioning of the coil during the conveying process, thereby improving the overall stability of the equipment and the precise control of the production process;

[0030] 3. The bending device, through the cooperation of the first clamping mechanism and the second clamping mechanism, achieves precise bending of the coil pins, improves product quality and consistency, and solves the problem of inconsistent pin bending in traditional manual operation.

[0042] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0043] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should be understood in their ordinary sense by those skilled in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different constituent devices.

[0044] For ease of understanding, in this embodiment, the length direction of the feeding device 8 is defined as the first direction and the length direction of the picking device 2 is defined as the second direction. Based on this, the coil winding and bending production line will be explained.

[0045] This application discloses a coil winding and bending production line. (Refer to...) Figure 1 The coil winding and bending production line includes a chassis 1, on which are sequentially arranged a winding device, a material handling device 2, a rotary feeding device 3, a bending device, a film-applying device 6, a lead-cutting device 7, a unloading device 8, and a receiving device 9. The winding device winds the raw materials into coils. The material handling device 2 transports the coils to the rotary feeding device 3, which simultaneously rotates multiple coils. The bending device bends the coil leads. The film-applying device 6 applies film to the coils. The unloading device 8 transfers the film-applied coils to the receiving device 9, which holds multiple formed coils. By adopting this technical solution, not only is the production space occupied reduced and safety risks lowered, but the process changeover speed and overall equipment stability are also improved, ensuring precise control during production and high-reliability product output.

[0046] Reference Figure 1 and Figure 2 The winding device is existing technology and will not be described in detail here. The material handling device 2 includes a three-axis moving module 21, a rotary drive assembly 22, and a feeding clamp 23. The three-axis moving module 21 drives the rotary drive assembly 22 to move along the X, Y, and Z directions. The rotary drive assembly 22 drives the feeding clamp 23 to rotate, and the feeding clamp 23 clamps the coil. In this embodiment, the rotary drive assembly 22 can be a first lifting drive 412 or a motor, and the feeding clamp 23 can be a first lifting drive 412. This facilitates the removal and fixing of the coil wound by the winding device, while simultaneously transferring the coil to the rotary feeding device 3. The coil is also kept straight, facilitating subsequent film application and lead cutting.

[0047] Reference Figure 3 and Figure 4The rotary feeding device 3 includes a turntable 31 and a rotary drive mechanism 32. The rotary drive mechanism 32 is mounted on the housing 1, and the turntable 31 is mounted on top of the rotary drive mechanism 32. The rotary drive mechanism 32 drives the turntable 31 to rotate intermittently. Multiple positioning seats 33 for positioning coils are spaced circumferentially along the upper surface of the turntable 31. In this embodiment, there are eight positioning seats 33, evenly distributed circumferentially. Each positioning seat 33 has a positioning groove 34 for positioning the coil at its top, and the shape of the positioning groove 34 matches the shape of the coil. In this embodiment, the rotary drive mechanism 32 can be a motor or a hydraulic motor. Under the drive of the rotary drive mechanism 32, the turntable 31 operates in an intermittent rotation mode, pausing after each 90° rotation to allow for the next operation. At each stage when the turntable 31 is paused, a positioning seat 33 is precisely moved to the bending device. At this time, the distance between the positioning seat 33 and the bending device is precisely adjusted to allow the bending device to perform effective bending operations on the coil in the positioning groove 34.

[0048] Continue to refer to Figure 3 and Figure 4 The shape of the positioning groove 34 can be customized according to the specific shape of the coil to ensure stable positioning of the coil. For example, if the coil is circular, the positioning groove 34 can be a circular groove; if the coil is rectangular, the positioning groove 34 can be a rectangular groove. In addition, elastic pads can be provided in the positioning groove 34 to further enhance the fixing effect of the coil.

[0049] In this embodiment, there are two bending devices, both mounted on the housing 1. These two bending devices are located between the material handling device 2 and the rotary feeding device 3, and are symmetrical to each other. During the rotation of the rotary feeding device 3, the turntable 31 drives the coil through the two bending devices sequentially, bending the leads located on both sides of the coil.

[0050] Reference Figure 1 and Figure 4 The bending device includes a first clamping mechanism 4 and a second clamping mechanism 5. During the rotation of the turntable 31, when the turntable 31 stops at a specific position, a positioning seat 33 is located between the first clamping mechanism 4 and the second clamping mechanism 5 each time. The first clamping mechanism 4 and the second clamping mechanism 5 are used to clamp the pins on both sides of the coil, respectively.

[0051] Reference Figure 3 and Figure 4The first clamping mechanism 4 includes a lifting drive assembly 41 and multiple first clamping assemblies 42. In this embodiment, each first clamping assembly 42 corresponds to a positioning seat 33 and is disposed on the positioning seat 33. The lifting drive assembly 41 is disposed on the chassis 1. During the rotation of the turntable 31, when the turntable 31 is in a stopped state, one of the first clamping assemblies 42 is always located directly above the lifting drive assembly 41.

[0052] Reference Figure 4 and Figure 5 Furthermore, the first clamping assembly 42 includes a mounting base 421, a clamping component 422, and a lifting base 423. The mounting base 421 is fixed to the positioning base 33. A first mounting groove 4211 is formed on the top of the mounting base 421, and a first isolation portion 4212 for isolating two pins on one side of the coil is integrally formed on the top of the mounting base 421. When the coil is placed in the positioning groove 34, the pins on one side of the coil are located on opposite sides of the first isolation portion 4212. The clamping component 422 includes two first clamping portions 4221, which pass through the first mounting groove 4211 and are rotatably connected to the mounting base 421. The first isolation portion 4212 is located between the two first clamping portions 4221, and the first isolation portion 4212 and the two first clamping portions 4221 together clamp and fix the two pins on one side of the coil. The lifting base 423 is located directly below the clamping component 422, and the lifting base 423 slides in engagement with the positioning base 33. The lifting drive assembly 41 is mounted on the chassis 1. The lifting drive assembly 41 is used to drive the lifting seat 423 to lift and lower, thereby simultaneously driving the two first clamping parts 4221 to rotate.

[0053] Continue to refer to Figure 4 and Figure 5In this embodiment, the positioning seat 33 has a lifting groove 35 on its side wall facing the lifting seat 423, and the lifting seat 423 slides in conjunction with the lifting groove 35. The specific lifting drive assembly 41 includes a first support 411, a first lifting drive component 412, and a lifting block 413. The first support 411 is fixed to the housing 1, and the first lifting drive component 412 is disposed on the first support 411. The first lifting drive component 412 is used to drive the lifting block 413 to rise and fall. In this embodiment, the first lifting drive component 412 can be a cylinder or an electric push rod. When the turntable 31 rotates, the first lifting drive component 412 drives the lifting block 413 to descend below the turntable 31, thereby ensuring that the lifting block 413 does not obstruct the rotating turntable 31. When the turntable 31 stops, the lifting seat 423 on the positioning seat 33 near the bending device rotates to directly above the lifting drive assembly 41. At this time, the lifting drive assembly 41 drives the lifting seat 423 to rise. When the lifting seat 423 rises, it simultaneously drives the two first clamping parts 4221 to rotate, so that the two first clamping parts 4221 clamp and fix the pin of the coil near the first clamping mechanism 4.

[0054] Reference Figure 6 and Figure 7 The second clamping mechanism 5 includes a transverse component 51, a pressing component 52, and a straightening and bending component 53. The transverse component 51 is mounted on the chassis 1. The transverse component 51 is used to drive the pressing component 52 and the straightening and bending component 53 to move along a first direction. The pressing component 52 is used to press the coil on the fixed positioning seat 33. The straightening and bending component 53 first straightens the two pins of the coil on the side away from the first clamping mechanism 4, and then bends the two pins of the coil on the side away from the first clamping mechanism 4.

[0055] Reference Figure 6 The lateral movement assembly 51 includes a support base 511, a lateral movement drive 512, and a lateral movement seat 513. The support base 511 is fixed to the chassis 1, and the lateral movement drive 512 is disposed on the support base 511. The lateral movement drive 512 permanently drives the lateral movement seat 513 to move along a first direction. The pressing assembly 52 and the straightening and bending assembly 53 are both disposed on the lateral movement seat 513. In this embodiment, the lateral movement drive 512 can be a cylinder or an electric push rod to achieve rapid horizontal movement.

[0056] Continue to refer to Figure 6 The pressing assembly 52 includes a first horizontal drive member 521, a second lifting drive member 522, and a pressing member 523. The first horizontal drive member 521 is mounted on the transverse seat 513. The first horizontal drive member 521 drives the second lifting drive member 522 to move along a second direction. The second lifting drive member 522 drives the pressing member 523 to move up and down. The pressing member 523 is used to press the coil on the fixed positioning seat 33. Specifically, both the first horizontal drive member 521 and the second lifting drive member 522 are cylinders.

[0057] Reference Figure 7 The straightening and bending assembly 53 includes a sliding member 531, a second horizontal drive member 532, a rotary drive member 533, a rotary member 534, and a second clamping assembly 535. The sliding member 531 slides in conjunction with the transverse base 513. The second horizontal drive member 532 is disposed on the transverse base 513 and is used to drive the sliding member 531 to move along a second direction. The rotary drive member 533 is disposed on the sliding member 531 and is used to drive the rotary member 534 to rotate. The second clamping assembly 535 is disposed on the rotary member 534 and is used to clamp the two pins on the other side of the coil. In this embodiment, the second horizontal drive member 532 is a cylinder, and the rotary drive member 533 is a motor.

[0058] Reference Figure 6 The second clamping assembly 535 includes a gripper cylinder 5351 and two second clamping parts 5352. A second mounting groove 5341 is provided on the rotating member 534, and both second clamping parts 5352 are rotatably disposed within the second mounting groove 5341. The gripper cylinder 5351 is disposed on the rotating member 534 and is used to drive the two second clamping parts 5352 to rotate. A second isolation part 5342 is integrally formed on the rotating member 534, located between the two second clamping parts 5352. The second isolation part 5342 and the two second clamping parts 5352 together clamp and fix the two pins on the other side of the coil. When the coil is placed in the positioning groove 34, the two pins of the coil near the second clamping mechanism 5 are located on opposite sides of the second isolation part 5342.

[0059] Reference Figure 6 and Figure 7 After the pressing assembly 52 presses and fixes the coil, the first clamping mechanism 4 clamps two pins on one side of the fixed coil, and the second clamping assembly 535 clamps two pins on the other side of the fixed coil. First, the two pins on the side of the coil away from the first clamping mechanism 4 are straightened by the combined action of the sliding member 531, the second horizontal driving member 532 and the second clamping assembly 535 in the straightening and bending assembly 53. Then, the two pins are bent by the combined action of the rotating member 534, the rotating driving member 533 and the second clamping assembly 535.

[0060] Reference Figure 1The film-applying device 6 includes a transport mechanism 61 and a film-applying mechanism 62, both of which are mounted on the housing 1. The transport mechanism 61 is located between the turntable 31 and the film-applying mechanism 62, and is used to transport coils. In this embodiment, the transport mechanism 61 is a robotic arm, which is also equipped with a vision detection component. The transport mechanism 61 is used to transport the coils on the turntable 31 to the film-applying mechanism 62, which automatically applies film to the coils. The robotic arm then transports the film-applied coils back to the positioning seat 33 on the turntable 31. During the rotation of the turntable 31, the film-applied coils are transported to the lead-cutting device 7.

[0061] Continue to refer to Figure 1 In this embodiment, the film-applying mechanism 62 and the cutting device 7 are both existing technologies, and their specific structures and principles will not be described in detail.

[0062] Reference Figure 1 and Figure 8 The feeding device 8 includes a first horizontal moving mechanism 81, a first lifting mechanism 82, and an adsorption mechanism 83. The first horizontal moving mechanism 81 is mounted on the housing 1. The first horizontal moving mechanism 81 is used to drive the first lifting mechanism 82 to move along a first direction. The first lifting mechanism 82 is used to drive the adsorption mechanism 83 to lift. The adsorption mechanism 83 is used to adsorb the coil, thereby facilitating the sequential transfer of finished products on the turntable 31 to the receiving device 9.

[0063] Reference Figure 1 The receiving device 9 includes a base 91, a second horizontal moving mechanism 92, and a second lifting mechanism 93. The base 91 is fixed to the housing 1. The second horizontal moving mechanism 92 is mounted on the base 91 and drives the second lifting mechanism 93 to move in a second direction. A tray 94 is mounted on the top of the second lifting mechanism 93, and the second lifting mechanism 93 drives the tray 94 to move up and down. Each tray 94 has multiple material slots arranged in a rectangular pattern, and each slot is used to hold bent coils. The base 91 also has multiple support mechanisms 95, each of which includes support components 951 symmetrically distributed on both sides of the base 91, thereby providing stable support for the tray 94. After the coils inside the tray 94 on the second lifting mechanism 93 are installed, the second horizontal moving mechanism 92 and the second lifting mechanism 93 sequentially transfer the tray 94 filled with coils to the multiple support mechanisms 95.

[0064] The implementation principle of the above embodiment is as follows: The production line winds the raw materials into coils through the winding device on the chassis 1. Then, the material handling device 2 uses the three-axis moving module 21 and the rotary drive assembly 22 to drive the loading clamping member 23 to clamp the coil and transport it to the turntable 31 of the rotary feeding device 3. The turntable 31 rotates intermittently under the drive of the rotary drive mechanism 32, so that the coils on multiple positioning seats 33 pass through two bending devices to bend the leads on both sides of the coil respectively. The bending device clamps the leads on both sides of the coil through the first clamping mechanism 4 and the second clamping mechanism 5 respectively. The first clamping mechanism 4 uses the lifting drive assembly 41 and the first clamping assembly 42 to achieve clamping, while the second clamping mechanism 5 completes the pressing, straightening and bending of the leads through the cooperation of the transverse moving assembly 51, the pressing assembly 52 and the straightening and bending assembly 53. Subsequently, the film-applying device 6 automatically applies film to the coil using the conveying mechanism 61 and the film-applying mechanism 62. Then, the unloading device 8 transports the finished coil to the receiving device 9 via the first horizontal moving mechanism 81, the first lifting mechanism 82, and the adsorption mechanism 83. The receiving device 9 drives the supporting mechanism 92 to move in a specific direction via the horizontal driving mechanism 91 to receive and hold multiple formed coils, thereby completing the entire coil winding and bending production process.
