Description

Technical Field

[0001] This utility model relates to the field of electronic FR-4 board terminal protection kit assembly technology, and more specifically, it relates to an electronic FR-4 board terminal protection kit assembly device. Background Technology

[0002] In the current electronics manufacturing industry, the electronic FR-4 board is an important basic component, and the protection of its terminals is crucial. Applying protective sleeves to the terminals is a key process to ensure the performance and safety of the terminals. Currently, the assembly of terminal protective sleeves is mostly done manually. Operators need to manually take the protective sleeves out of the material box and then align them with the terminals on the FR-4 board to apply them. This method is not only labor-intensive and prone to operator fatigue due to long hours of work, but also prone to problems such as improper fitting, misalignment, or even damage to the terminals due to the instability of human operation, which seriously affects product quality.

[0003] As production efficiency requirements increase, some companies have begun to adopt simple semi-automatic assembly equipment. However, these devices have many limitations. Specifically, when fixing FR-4 boards, the existing equipment lacks a flexible and precise positioning structure, making it difficult to adapt to the clamping requirements of FR-4 boards of different specifications. This often results in board shaking or displacement, leading to misalignment between the protective sleeve and the terminals.

[0004] Meanwhile, the mechanical structure has insufficient range of motion and flexibility when picking up and putting down protective sleeves, making it impossible to quickly and accurately pick up materials from the raw material box and transfer them to the assembly position, which affects assembly efficiency. In addition, the protective sleeves are prone to accumulating and getting stuck in the box, requiring frequent manual sorting, and cannot achieve continuous and stable material supply. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an assembly device for the terminal protection of electronic FR-4 board, so as to solve the technical problems mentioned in the background art of the lack of flexible and precise positioning structure and insufficient assembly flexibility in the prior art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An assembly device for a terminal protection kit on an electronic FR-4 board includes a support plate. A sliding groove is provided on the rear side of the support plate, and a sliding rod is disposed within the sliding groove. An auxiliary block is disposed on the sliding rod, and the auxiliary block is threadedly connected to the sliding rod. The sliding groove and the auxiliary block are fitted together and slidably connected. A connecting frame is provided at the upper end of the auxiliary block, and a robotic arm is provided at the upper end of the connecting frame. A mechanical gripper is provided at one end of the robotic arm. A first motor is disposed on one side wall of the support plate, and one end of the sliding rod is connected to the output end of the first motor. A three-jaw chuck with a rotating component is disposed on the upper side wall of the support plate. A raw material box is disposed on one side wall of the support plate, and an auxiliary component is disposed within the raw material box. A storage box with a disassembly component is disposed on the other side wall of the support plate.

[0007] The present invention is further configured such that the rotating assembly includes a second motor and a rotating rod, the second motor is inside the support plate, the rotating rod is on the side wall of the support plate, the lower end of the rotating rod is connected to the output end of the second motor, and the three-jaw chuck is on the upper end of the rotating rod, which can adjust the angle of the three-jaw chuck and the fixed FR-4 plate, so as to facilitate the mechanical jaws to be assembled from different positions and improve the operational flexibility.

[0008] The present invention is further configured such that the auxiliary component includes an electromagnetic slide rail, a control magnetic block, a connecting plate, and a push plate. The electromagnetic slide rail is located on one side of the raw material box, the control magnetic block is on the electromagnetic slide rail and is electromagnetically slidably connected to it, the connecting plate is located on one side of the control magnetic block, and the push plate is located at the lower end of the connecting plate and is adapted to the side wall of the raw material box. This allows the protective sleeve inside the raw material box to be pushed to a position that is easy for the mechanical gripper to grasp, thus avoiding the accumulation of the protective sleeve and ensuring smooth material supply.

[0009] The present invention is further configured such that the disassembly assembly includes a slide rail and a mounting block. The slide rail is symmetrically arranged on both sides of the support plate, the mounting block is inside the slide rail and slidably connected to it, and the storage box is between the two mounting blocks, so that the storage box can be easily slidably installed and removed, facilitating quick replacement or cleaning of the storage box and improving the continuity of operation.

[0010] The present invention is further configured such that a support frame is provided at one corner of the side wall of the support plate, and a camera is provided at the lower end of the support frame, which can monitor the assembly process in real time, detect assembly deviations or defects in a timely manner, and help ensure assembly quality.

[0011] The present invention is further provided with a handle with anti-slip texture on one side wall of the storage box, which makes it convenient for operators to hold and put in and take out the storage box, thereby improving the ease of use.

[0012] The present invention is further provided with a flexible rubber pad on the inner side of the mechanical gripper, and the surface of the flexible rubber pad is provided with anti-slip texture, which can not only firmly grip the protective sleeve, but also prevent the protective sleeve from being damaged by excessive gripping force, thus playing a protective role.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an electronic FR-4 board terminal protection kit, which has the following advantages: 1. The sliding groove on the rear side of the support plate cooperates with the sliding rod. Driven by the first motor, it can drive the auxiliary block, connecting frame and mechanical arm to move smoothly along the sliding direction, so that the mechanical gripper can flexibly adjust the lateral position to adapt to the assembly requirements of different specifications of FR-4 plates. This movable design breaks through the limitation of fixed working range, making the operation of the mechanical gripper more flexible in material picking, assembly and other links, and reducing the problem of inconvenience in adjustment caused by fixed position.

[0014] 2. The rotating component further enhances the adaptability of the device. When the first motor drives the rotating rod to rotate, the angle of the three-jaw chuck and the fixed FR-4 plate can be easily adjusted, so that each terminal on the plate can be conveniently aligned with the working position of the mechanical jaws. Whether it is a single row of terminals or multiple rows of terminals, precise alignment can be achieved by adjusting the angle, avoiding the tediousness of frequently moving the robotic arm due to the fixed angle of the plate, and significantly improving the smoothness of the assembly operation.

[0015] 3. The three-jaw chuck, as a fixing component for the FR-4 board, can firmly clamp boards of different sizes by adjusting the gap between the jaws, ensuring that the board will not shake or shift during assembly, providing a stable foundation for the accurate placement of the protective sleeve. The auxiliary components in the material box can organize and push the protective sleeve in an orderly manner, ensuring that the mechanical jaws can stably pick up materials. The storage box with disassembly components facilitates the collection and transfer of products after assembly, reducing the time loss between processes. Attached Figure Description

[0021] Please see Figure 1-5 An assembly device for a terminal protection kit on an electronic FR-4 board includes a support plate 1. A sliding groove is provided on the rear side of the support plate 1, and a sliding rod 2 is provided in the sliding groove. An auxiliary block 3 is provided on the sliding rod 2. The auxiliary block 3 is threadedly connected to the sliding rod 2. The sliding groove is fitted and slidably connected to the auxiliary block 3. A connecting frame 4 is provided on the upper end of the auxiliary block 3. A robotic arm 5 is provided on the upper end of the connecting frame 4. A mechanical gripper 6 is provided at one end of the robotic arm 5. A first motor 7 is provided on one side wall of the support plate 1. One end of the sliding rod 2 is connected to the output end of the first motor 7. A three-jaw chuck 8 with a rotating component is provided on the upper side wall of the support plate 1. A raw material box 9 is provided on one side wall of the support plate 1. An auxiliary component is provided in the raw material box 9. A storage box 10 with a disassembly component is provided on the other side wall of the support plate 1.

[0022] The rotating assembly includes a second motor 11 and a rotating rod 12. The second motor 11 is inside the support plate 1, and the rotating rod 12 is on the upper side wall of the support plate 1. The lower end of the rotating rod 12 is connected to the output end of the second motor 11, and the three-jaw chuck 8 is on the upper end of the rotating rod 12.

[0023] In this embodiment, during operation, the electronic FR-4 board to be assembled is first placed on the three-jaw chuck 8. By adjusting the jaw spacing of the three-jaw chuck 8, the FR-4 board is firmly fixed to ensure that the board will not shake during assembly. Subsequently, the auxiliary components in the material box 9 start working, tidying up the protective sleeve and pushing it to a position that is easy for the mechanical gripper 6 to grasp. At this time, the first motor 7 starts, driving the sliding rod 2 to rotate. Since the auxiliary block 3 is threadedly connected to the sliding rod 2 and slides in contact with the sliding groove, the rotation of the sliding rod 2 is converted into the horizontal movement of the auxiliary block 3. Then, through the connecting frame 4, the robotic arm 5 and the mechanical gripper 6 move along the sliding direction, so that the mechanical gripper 6 accurately reaches the material box 9 to grasp the protective sleeve. After grasping the protective sleeve, the robotic arm 5 moves above the three-jaw chuck 8 under the drive of the sliding component. At the same time, the second motor 11 drives the rotating rod 12 to rotate, driving the three-jaw chuck 8 and the FR-4 board to adjust the angle so that the terminal to be assembled is aligned with the mechanical gripper 6. The robotic arm 5 manipulates the mechanical gripper 6 to accurately put the protective sleeve on the terminal, completing one assembly.

[0024] More specifically, if there are multiple terminals on the FR-4 board that need to be assembled, the rotating component can continue to adjust the board angle, and the sliding component can drive the robotic arm 5 to move. With the flexible movement of the robotic arm 5, the protective assembly of all terminals can be completed. After the assembly is completed, the robotic arm 5 will transfer the FR-4 board to the storage box 10. The storage box 10 with the disassembly component can facilitate the centralized processing of the finished product in the future.

[0025] Please see Figures 1-5 As one implementation of the auxiliary component: the auxiliary component includes an electromagnetic slide rail 13, a control magnetic block 14, a connecting plate 15 and a push plate 16. The electromagnetic slide rail 13 is on one side of the raw material box 9. The control magnetic block 14 is on the electromagnetic slide rail 13 and is electromagnetically slidably connected to it. The connecting plate 15 is on one side of the control magnetic block 14. The push plate 16 is at the lower end of the connecting plate 15 and is adapted to the side wall of the raw material box 9.

[0026] Specifically, after the electromagnetic slide rail 13 is energized, it generates magnetic force. The control magnetic block 14 slides along the electromagnetic slide rail 13 under the action of electromagnetic force. The connecting plate 15 drives the lower push plate 16 to move synchronously. The push plate 16 is adapted to the side wall of the raw material box 9. As the control magnetic block 14 moves, the push plate 16 also moves to push the protective sleeve inside the box forward, so that the frontmost protective sleeve is in a position that the mechanical gripper 6 can easily grasp, thus avoiding the protective sleeve from accumulating inside the box and causing the gripper to have difficulty picking up the material.

[0027] Please see Figures 1-5 As one implementation of the disassembly assembly: the disassembly assembly includes a slide 17 and a mounting block 18. The slide 17 is symmetrically arranged on both sides of the support plate 1. The mounting block 18 is in the slide 17 and slidably connected to it. The storage box 10 is between the two mounting blocks 18. A handle 21 with anti-slip texture is provided on one side wall of the storage box 10.

[0028] Specifically, the operator holds the handle 21 with anti-slip texture on the side wall of the storage box 10 and pushes the mounting block 18 along the slide 17 on both sides of the support plate 1, so that the mounting block 18, along with the storage box 10, slides out of the slide 17 and the finished product can be taken out. When replacing an empty storage box 10, the mounting block 18 of the new storage box 10 is aligned with the slide 17 and pushed in until it is installed in place, and the storage work continues.

[0029] Please see Figures 1-5 As one embodiment of the camera 20: a support frame 19 is provided at one corner of the upper side wall of the support plate 1, and the camera 20 is provided at the lower end of the support frame 19.

[0030] Specifically, camera 20 captures real-time images of the assembly area to monitor the position of the mechanical gripper 6 and the alignment of the protective sleeve with the terminals.

[0031] Please see Figures 1-5 As one embodiment of the flexible rubber pad: a flexible rubber pad is provided on the inner side of the mechanical gripper 6, and the surface of the flexible rubber pad is provided with anti-slip texture.

[0032] Specifically, when the mechanical gripper 6 closes, the flexible rubber pad on its inner side will adhere to the surface of the protective sleeve. The elasticity of the rubber can prevent the gripper from damaging the protective sleeve due to excessive force, while the anti-slip texture on the surface can increase the friction with the protective sleeve, ensuring a firm grip and preventing slippage.

[0033] In summary, when using the overall equipment: Before starting the work, place the electronic FR-4 board to be assembled with protective sleeves on the three-jaw chuck 8. By adjusting the jaw spacing of the three-jaw chuck 8, the FR-4 board is firmly fixed by the clamping force of the jaws on the board (this is a common and mature device on the market, which will not be described in detail in this article). This ensures that the board will not shake or shift during the assembly process, providing a stable foundation for subsequent precise assembly. At the same time, put an appropriate amount of terminal protective sleeves into the material box 9, ready to start the device.

[0034] After the device is started, the first motor 7 is powered on and begins to run. Its output end drives the sliding rod 2 to rotate. Since the auxiliary block 3 is threadedly connected to the sliding rod 2 and the auxiliary block 3 slides in contact with the sliding groove, the rotational motion of the sliding rod 2 is converted into the horizontal linear motion of the auxiliary block 3 through the threaded transmission. Then, through the connecting frame 4, the mechanical arm 5 and the mechanical gripper 6 move smoothly along the sliding groove, so that the mechanical gripper 6 can move accurately to the raw material box 9.

[0035] When the mechanical gripper 6 moves above the raw material box 9, the electromagnetic slide rail 13 is energized and generates an alternating magnetic field. The control magnetic block 14 slides back and forth along the electromagnetic slide rail 13 under the action of electromagnetic force. The principle is to use the force of the magnetic field on the magnet to drive the control magnetic block 14 to move. The control magnetic block 14 drives the lower push plate 16 to move synchronously through the connecting plate 15. The push plate 16 is adapted to the side wall of the raw material box 9 and can slide against the inner wall of the raw material box 9, pushing the protective sleeves accumulated in the raw material box 9 forward, so that the frontmost protective sleeve is in a position that the mechanical gripper 6 can easily grasp, avoiding the difficulty of the gripper picking up the material due to the accumulation of protective sleeves, and ensuring the continuity and stability of the material supply.

[0036] When the mechanical gripper 6 is ready to grasp the protective sleeve, its inner flexible rubber pad will contact the surface of the protective sleeve. The elasticity of the rubber pad can buffer the gripping force of the gripper and prevent damage to the protective sleeve due to excessive gripping force. At the same time, the anti-slip texture on the surface of the rubber pad increases the friction between it and the protective sleeve. The friction is used to ensure that the protective sleeve will not slip during the grasping and transfer process, thus ensuring the reliability of material handling.

[0037] After grabbing the protective sleeve, the robotic arm 5 moves above the three-jaw chuck 8 under the drive of the sliding rod 2 and the auxiliary block 3. At this time, the rotating component starts to operate. The second motor 11 in the support plate 1 drives the rotating rod 12 to rotate. The rotating rod 12 drives the FR-4 plate to rotate around the vertical axis through the fixed connection with the three-jaw chuck 8, so that the terminal to be assembled is accurately aligned with the mechanical gripper 6.

[0038] As the mechanical gripper 6 moves the protective sleeve onto the terminal, the camera 20 at the lower end of the support frame 19 on the upper side wall of the support plate 1 captures real-time images of the assembly area for the operator to observe.

[0039] Once the protective sleeve for one terminal is assembled, if there are other terminals on the FR-4 board that need to be assembled, the rotating component will continue to adjust the board angle, and the sliding component will drive the robotic arm 5 to move. In conjunction with the multi-joint movement of the robotic arm 5, the above-mentioned material picking, alignment, and assembly process will be repeated until the protective sleeve assembly for all terminals is completed.

[0040] After assembly, the robotic arm 5 removes the FR-4 plate from the three-jaw chuck 8 and transfers it into the storage box 10. When the storage box 10 is full of assembled FR-4 plates, the operator holds the handle 21 with anti-slip texture on the side wall of the storage box 10 and pushes the mounting block 18 along the slide rails 17 on both sides of the support plate 1. The mounting block 18 slides in the slide rails 17, causing the storage box 10 to be removed from the device. When replacing the empty storage box 10, simply align the mounting blocks 18 on both sides of the new storage box 10 with the slide rails 17 and push it in until it is in place, and then the storage work can continue.
