Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing equipment technology, specifically a PCB small board take-up machine. Background Technology

[0002] Miniature PCBs, or small printed circuit boards, are typically less than 100mm in side length and 0.5-1.2mm in thickness. Compared to regular PCBs, they are characterized by high-density integrated design, narrower wiring spacing, and smaller via diameters, accommodating micro-surface mount components such as 0201 and even 01005 micro-mount devices. They utilize special substrates such as high-frequency boards and flexible materials, combined with precision processes like laser drilling and micro-hole plating, to meet the special requirements of high-speed signal transmission and bending. These boards are widely used in consumer electronics (such as mobile phone camera modules and TWS earphone motherboards), medical sensors, and automotive electronics, serving as key components for circuit connections and component support within confined spaces, enabling the miniaturization and modularization of electronic devices.

[0003] Currently, PCB small board receiving machines are typically equipped with collection frames to store processed boards. However, existing receiving machines suffer from poor shock absorption in the collection frames due to factors such as the impact of the robotic arm placing the boards and the vibration of the conveyor belt during the collection process. This makes it easy for thin, densely packed PCB small boards to experience problems such as component solder joint cracking and board warping when stacked, seriously affecting product yield. At the same time, vibration can also cause misalignment of boards stacked within the collection frame, reducing receiving efficiency and increasing equipment maintenance costs, necessitating improvements.

[0004] To address these issues, we designed a PCB small board receiving machine. Utility Model Content

[0005] The purpose of this utility model is to provide a PCB small board take-up machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a PCB small board receiving machine, including a mounting frame, a fixed plate fixedly mounted on the mounting frame, a connecting plate disposed above the fixed plate, a second U-shaped block mounted on the top of the fixed plate, and a first U-shaped block fixedly mounted on the bottom of the connecting plate. A circular plate is fixedly mounted on both the first and second U-shaped blocks, and an elastic element, a damper, and a shock-absorbing spring are installed between two adjacent circular plates, with the shock-absorbing spring sleeved outside the damper.

[0007] Furthermore, the elastic element is elliptical in shape and is made of spring steel.

[0008] Furthermore, the mounting bracket is U-shaped, and a collection box is provided inside the mounting bracket, which is located on top of the connecting plate.

[0009] Furthermore, the mounting frame is equipped with two sets of limiting rods, with each set containing one limiting rod, and the limiting rods are located on both sides of the collection box.

[0010] Furthermore, a transfer device is provided on one side of the mounting bracket, and a chip mounter is installed at the end of the transfer device away from the mounting bracket.

[0011] Furthermore, guide blocks are installed on both sides of the connecting plate, and guide grooves adapted to the guide blocks are provided inside the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the PCB small board receiving machine is running, external forces such as the impact of the robotic arm placing the board and the vibration of the conveyor belt are transmitted to the collection box, causing the connecting plate to vibrate. The elastic elements, dampers, and shock-absorbing springs on the first and second U-shaped blocks work together. The elastic elements absorb vibration energy through elastic deformation, the shock-absorbing springs buffer the impact, and the dampers hinder the transmission of vibration and convert the energy into heat energy, effectively suppressing the vibration amplitude of the connecting plate and the collection box, and reducing the impact on the PCB small board.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the elastic element adopts an elliptical structure, which, compared with the conventional circular or rectangular elastic structure, can produce differentiated deformation according to different directions when subjected to force, flexibly adapting to multi-angle force under complex vibration environment, and effectively absorbing vibration energy in all directions; the spring steel material is selected, which, with its good elasticity and strength, can still maintain stable elastic performance after repeated force, ensuring that the elastic element continues to play a reliable shock absorption role during long-term operation of the board collecting machine, reducing damage and stacking misalignment of PCB small boards in the collection box caused by vibration.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a PCB small board receiving machine, including a mounting frame 3, a fixing plate 6 fixedly mounted on the mounting frame 3, a connecting plate 7 above the fixing plate 6, a second U-shaped block 13 mounted on the top of the fixing plate 6, a first U-shaped block 8 fixedly mounted on the bottom of the connecting plate 7, a circular plate 10 fixedly mounted on both the first U-shaped block 8 and the second U-shaped block 13, and an elastic element 9, a damper 11, and a shock-absorbing spring 12 installed between two adjacent circular plates 10, with the shock-absorbing spring 12 sleeved on the outside of the damper 11.

[0021] In practice, when the PCB small board receiving machine is running, external forces such as the impact of the robotic arm placing the board and the vibration of the conveyor belt are transmitted to the collection box 5, which in turn causes the connecting plate 7 to vibrate. At this time, the elastic element 9, damper 11, and shock-absorbing spring 12 installed on the first U-shaped block 8 and the second U-shaped block 13 begin to work together. Due to its spring steel material and elliptical structure, the elastic element 9 can undergo elastic deformation when subjected to force, absorbing vibration energy and converting it into its own elastic potential energy; the shock-absorbing spring 12 is sleeved on the outside of the damper 11, and the elastic extension and contraction of the spring itself can buffer the vibration impact. At the same time, the damper 11 generates damping force through the flow of internal liquid or gas, which hinders the rapid transmission and continuous oscillation of vibration, converting vibration energy into heat energy and dissipating it. The combination of the two effectively suppresses the vibration amplitude of the connecting plate 7 and the collection box 5, reducing the impact of vibration on the PCB small boards inside the collection box 5.

[0022] The combination of elastic element 9, damper 11, and shock-absorbing spring 12 forms a multi-stage shock absorption system, which can more comprehensively absorb vibrations of different frequencies and directions compared to a single shock absorption element. For small PCB components, this effectively reduces problems such as component solder joint cracking and board warping caused by vibration, ensuring product yield. In terms of board collection efficiency, it avoids misalignment of boards stacked in the collection box 5 caused by vibration, making the robotic arm more precise and efficient in picking up and placing boards, and reducing adjustment time during the board collection process. In addition, the limiting rod 4 on the mounting bracket 3 further restricts the displacement of the collection box 5, and the cooperation between the guide block and the guide groove ensures that the connecting plate 7 moves smoothly during the shock absorption process, enhancing the overall structural stability and reducing equipment failures such as component loosening and wear caused by vibration, thereby reducing maintenance costs.

[0023] See Figure 1-4 The elastic element 9 is elliptical in shape and is made of spring steel.

[0024] In practical implementation, the elastic element 9 is set as an ellipse. Compared with conventional circular or rectangular elastic structures, its deformation degree varies in different directions when subjected to force. It can flexibly undergo elastic deformation in multiple directions, adapt to force changes in complex vibration environments, and effectively absorb vibration energy from different angles. Spring steel is used as the material of the elastic element 9. Spring steel has good elasticity and strength. It is not easy to undergo plastic deformation after repeated stress deformation. It can maintain its elastic performance stably for a long time, ensuring that the elastic element 9 always has reliable shock absorption capability during long-term use of the board collecting machine, continuously protecting the PCB small boards in the collection box 5, and reducing board damage and stacking misalignment caused by vibration.

[0025] See Figure 1-4 The mounting bracket 3 is U-shaped, and a collection box 5 is installed inside the mounting bracket 3. The collection box 5 is located on top of the connecting plate 7.

[0026] In practice, the mounting frame 3 is U-shaped, forming a semi-enclosed spatial structure that provides a stable installation boundary and protective frame for the collection box 5. This effectively limits the horizontal displacement of the collection box 5 and enhances the stability of its installation. The collection box 5 is placed on top of the connecting plate 7, and the mounting frame 3 has reserved space inside for the collection box 5, allowing the collection box 5 to be tightly integrated with the connecting plate 7. This facilitates the transmission of vibration buffering components such as the elastic element 9, damper 11, and shock-absorbing spring 12 to the collection box 5 after the connecting plate 7 has been subjected to vibration. At the same time, the U-shaped mounting frame 3, in conjunction with the connecting plate 7, provides vertical and horizontal limits for the collection box 5, ensuring its stability during the operation of the board collecting machine and reducing damage to internal PCB components caused by shaking or displacement.

[0027] See Figure 1-4The mounting frame 3 is equipped with two sets of limiting rods 4, with each set containing 3 limiting rods 4. The limiting rods 4 are located on both sides of the collection box 5.

[0028] In practice, two sets of limiting rods 4, each set consisting of three rods, are installed on the mounting frame 3. The limiting rods 4 are positioned on both sides of the collection box 5, restricting the collection box 5 from multiple points. This effectively constrains the movement of the collection box 5 in the horizontal direction. When the board collecting machine vibrates during operation, it prevents the collection box 5 from shifting laterally or longitudinally within the mounting frame 3. At the same time, the multiple limiting rods 4 form a stable limiting structure, enhancing the fixing effect on the collection box 5. Combined with vibration damping components such as elastic element 9, damper 11, and shock-absorbing spring 12, it further reduces the shaking of the collection box 5 caused by vibration, ensuring that the PCB small boards inside the collection box 5 remain neat during stacking and reducing the risk of collision and damage caused by changes in board position.

[0029] See Figure 1-4 A transfer device 2 is provided on one side of the mounting frame 3, and a pick-and-place machine 1 is installed on the end of the transfer device 2 away from the mounting frame 3.

[0030] In practice, a conveying device 2 is installed on one side of the mounting frame 3, and a pick-and-place machine 1 is installed at the end of the conveying device 2 away from the mounting frame 3. This creates a continuous production line layout for the pick-and-place machine 1, the conveying device 2, and the mounting frame 3. After the pick-and-place machine 1 completes the component placement process, the PCB small boards can be directly and quickly and stably transported to the collection box 5 on the mounting frame 3 via the conveying device 2. This reduces manual transfer steps and lowers the possibility of damage to the boards during transfer. At the same time, this layout makes the connection between the various devices more compact, saves production space, improves production efficiency, and facilitates unified management and monitoring of the entire production line by operators, allowing for timely handling of problems that arise during production.

[0031] See Figure 1-4 Guide blocks are installed on both sides of the connecting plate 7, and guide grooves that are compatible with the guide blocks are provided inside the mounting bracket 3.

[0032] In practice, guide blocks are installed on both sides of the connecting plate 7, and a matching guide groove is set inside the mounting frame 3. When the board collecting machine is running, the guide blocks can move along the guide groove to provide precise guidance for the movement of the connecting plate 7, ensuring that the connecting plate 7 will not shift or tilt during the up and down vibration. This allows the elastic element 9, damper 11, and shock-absorbing spring 12 to play a shock-absorbing role in the correct position, effectively improving the shock absorption effect. At the same time, the cooperation between the guide blocks and the guide groove can also enhance the stability of the connecting plate 7 installation, limit its swaying in the horizontal direction, reduce the impact of the instability of the connecting plate 7 on the small PCB components in the collection box 5, and ensure that the components remain neat and safe during the collection process.

[0033] Working Principle: When the PCB small board receiving machine is running, external forces such as the impact of the robotic arm placing the board and the vibration of the conveyor belt are transmitted to the collection box 5, which in turn causes the connecting plate 7 to vibrate. At this time, the elastic element 9, damper 11, and shock-absorbing spring 12 installed on the first U-shaped block 8 and the second U-shaped block 13 begin to work together. Due to its spring steel material and elliptical structure, the elastic element 9 can undergo elastic deformation when subjected to force, absorbing vibration energy and converting it into its own elastic potential energy; the shock-absorbing spring 12 is sleeved on the outside of the damper 11, and the elastic extension and contraction of the spring itself can buffer the vibration impact. At the same time, the damper 11 generates damping force through the flow of internal liquid or gas, hindering the rapid transmission and continuous oscillation of vibration, and converting vibration energy into heat energy for dissipation. The combination of these two effectively suppresses the vibration amplitude of the connecting plate 7 and the collection box 5, reducing the impact of vibration on the PCB small boards inside the collection box 5.

[0034] The combination of elastic element 9, damper 11, and shock-absorbing spring 12 forms a multi-stage shock absorption system, which can more comprehensively absorb vibrations of different frequencies and directions compared to a single shock absorption element. For small PCB components, this effectively reduces problems such as component solder joint cracking and board warping caused by vibration, ensuring product yield. In terms of board collection efficiency, it avoids misalignment of boards stacked in the collection box 5 caused by vibration, making the robotic arm more precise and efficient in picking up and placing boards, and reducing adjustment time during the board collection process. In addition, the limiting rod 4 on the mounting bracket 3 further restricts the displacement of the collection box 5, and the cooperation between the guide block and the guide groove ensures that the connecting plate 7 moves smoothly during the shock absorption process, enhancing the overall structural stability and reducing equipment failures such as component loosening and wear caused by vibration, thereby reducing maintenance costs.
