Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, specifically a PCB board disassembly device. Background Technology

[0002] During PCB manufacturing, PCB boards and stencils are placed alternately. The stencils, with their thickness, not only isolate the upper and lower PCB boards but also help shape the PCBs. After shaping, the PCB boards and stencils need to be separated. A common separation device is the PCB thin-board automatic handling and packaging equipment disclosed in the prior art (publication number: CN115649545B), which includes a conveyor line and a handling mechanism. The handling mechanism picks up the PCB board and transports it to a dedicated PCB board conveyor line. However, the existing technology has a technical problem: the stencil must be removed from the PCB board before picking it up. A common method is to set up a separate handling mechanism to pick up the stencil and transport it to a dedicated stencil conveyor line. These two handling devices are relatively independent, resulting in low removal efficiency. Furthermore, if one handling device malfunctions, the two devices are prone to collision, potentially leading to serious production safety accidents. Utility Model Content

[0003] This invention provides a PCB board disassembly device that can improve the reliability of the disassembly device.

[0004] This application provides the following technical solution:

[0005] A PCB board disassembly device includes: a conveying mechanism, the conveying mechanism including a first conveying component and a second conveying component, a connecting component fixedly disposed between the first conveying component and the second conveying component, such that the horizontal distance between the first conveying component and the second conveying component remains unchanged; a first conveyor line for conveying alternately placed PCB boards and steel plates; a second conveyor line for conveying PCB boards; and a third conveyor line for conveying steel plates.

[0006] Beneficial effects:

[0007] 1. High-efficiency dismantling and conveying: The system utilizes a coordinated first and second transporter to alternately transfer PCB boards and steel plates from the first conveyor line to the second and third conveyor lines. Specifically, while the first transporter places the PCB board onto the second conveyor line, the second transporter simultaneously picks up the steel plate from the first conveyor line. This design significantly improves dismantling efficiency, enabling simultaneous processing of PCB boards and steel plates. The coordinated operation of the first and second transporters makes the entire dismantling process smoother, reduces the time spent on multiple operations, and greatly improves production efficiency.

[0008] 2. Enhanced Operational Safety: The integrated linkage of the first and second transport components prevents collisions between them. This integrated design precisely controls the movements of the two transport components, ensuring they do not interfere with or collide during operation, thus improving operational safety. Especially on high-speed production lines, this design effectively prevents serious production safety accidents caused by equipment failure or operational errors, ensuring stable production line operation and personnel safety.

[0009] 3. Precise Positioning and Smooth Operation: A connecting component ensures a constant horizontal distance between the first and second transport components, guaranteeing precise positioning and smooth operation. This fixed-distance design not only ensures consistency and accuracy in every transport action but also simplifies the control system design, reducing debugging and maintenance workload. Furthermore, the stable distance enhances the suction effect of the suction cups or other gripping devices, ensuring the smooth pickup and transport of PCB boards and steel plates, further improving the overall reliability and efficiency of the equipment.

[0010] In summary, this PCB board dismantling equipment achieves efficient dismantling and transport of PCB boards and stencils through the integrated and linked first and second transport components. The collaborative operation mode improves dismantling efficiency and reduces single-operation time; the integrated and linked design avoids collisions between transport devices, enhancing operational safety; and the fixed horizontal spacing ensures accurate positioning and smooth operation. These improvements work together to enable the equipment to more efficiently and safely complete the dismantling of PCB boards and stencils in practical applications, significantly improving production continuity and stability, and significantly enhancing the reliability of the dismantling equipment compared to existing technologies.

[0011] Furthermore, as an improvement, the third conveyor line is integrated into the first conveyor line.

[0012] Beneficial effects: This design significantly reduces the overall space occupied by the equipment, making the production line layout more compact and efficient. By integrating the third conveyor line into the first conveyor line, not only is additional installation space saved, but the connection and coordination between equipment are also simplified. For steel plates that need to be reused, the integrated design allows the steel plates to return to the first conveyor line more easily after completing a splitting and overlapping process, forming a closed-loop workflow. This seamless connection not only improves material flow efficiency but also reduces potential errors and time losses caused by complex handling paths.

[0013] Furthermore, as an improvement, inclined baffles are provided on both sides of the third conveyor line along the conveying direction, and compression springs for resetting the inclined baffles are provided at the bottom of the inclined baffles.

[0014] Beneficial Effects: This design significantly enhances the limiting and guiding functions of the steel plate, ensuring its smooth transport to the next processing area. The inclined baffle design increases the blocking area for the steel plate, providing more stable lateral support and preventing it from shifting or tipping during transport, thus ensuring the smoothness and reliability of the transport process. Furthermore, the inclusion of a return spring further enhances the system's safety and stability. If a steel plate is accidentally placed on top of the baffle, the baffle automatically returns to a horizontal position under the weight of the steel plate, preventing the baffle end from scratching the steel plate. This adaptive design not only protects the integrity of the steel plate surface but also ensures the quality of subsequent PCB board pressing, reducing the defect rate in production.

[0015] Furthermore, as an improvement, the connecting member is made of steel frame, and both the first and second transport members include sliders, with the steel frame fixedly connected to the sliders in the first and second transport members respectively.

[0016] Beneficial effects: The steel frame is used to fix the first and second transport components, so that the distance between the first and second transport components remains unchanged during the sliding process. The connection position of the steel frame is selected on the sliders of the first and second transport components to ensure that the first and second transport components can have different vertical movements, thus ensuring the different height requirements of the PCB board and steel plate picking process.

[0017] Furthermore, as an improvement, the third conveying line uses a roller conveyor, which includes several rollers with the same gap. A frame is fixedly installed around the feed end of the roller conveyor, and several supports are movably installed within the frame. The direction of movement of the supports is perpendicular to the direction in which the roller conveyor conveys the steel plate, so that when the supports are in their initial positions, the top height of the supports can be higher than the set height of the rollers.

[0018] Beneficial Effects: The roller conveyor operates without stopping during production. By using supports to facilitate the placement and transfer of steel plates, a seamless operational process is achieved. This design not only improves production efficiency but also ensures the continuity and stability of the production line, reducing production interruptions and wasted time due to downtime adjustments. Specifically, by first placing the steel plate on the support, then releasing the second conveyor from the support and lowering the support to allow the steel plate to contact the roller, direct contact between the steel plate and the running roller is avoided. If the steel plate contacts the roller without timely releasing the second conveyor from its restraints, the bottom panel of the steel plate will be scratched, affecting the quality of subsequent pressing of new batches of PCB boards. The bracket and support setup not only protects the surface quality of the steel plate but also reduces direct friction and impact between the rollers, extending the service life of the roller conveyor and its components.

[0019] Furthermore, as an improvement, the second conveyor line uses trolleys.

[0020] Beneficial effects: This design significantly enhances the flexibility and mobility of the conveyor system. The trolleys can flexibly transport PCB boards to any required area according to actual production needs, without being restricted by fixed conveyor line paths. Since PCB boards are products manufactured by this equipment, the trolleys allow for rapid response to changes in the production line or urgent needs, quickly adjusting the transport destination of the PCB boards and improving production adaptability and responsiveness.

[0022] Figure 2 for Figure 1 Left view of the inclined baffle 304;

[0023] Figure 3 for Figure 1 Top view of the third conveyor line 300. Detailed Implementation

[0024] The following detailed description illustrates the specific implementation method:

[0025] The markings in the accompanying drawings include: first conveyor line 100, second conveyor line 200, third conveyor line 300, roller 301, frame 302, support 303, inclined baffle 304, compression spring 305, conveying mechanism 400, first suction cup 401, first slider 402, second suction cup 403, second slider 404, slide rail 405, steel frame 406, PCB board 500, and steel plate 600.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a PCB board 500 disassembly device includes a handling mechanism 400, a first conveyor line 100, a second conveyor line 200, and a third conveyor line 300.

[0028] The conveying mechanism 400 includes a first suction cup 401, a first slider 402, a second suction cup 403, a second slider 404, and a slide rail 405. The first slider 402 and the second slider 404 are slidably connected to the slide rail 405. The first suction cup 401 is fixedly connected to the bottom of the first slider 402, and the second suction cup 403 is fixedly connected to the bottom of the second slider 404. A connecting member is fixedly provided between the first and second conveying components to keep the horizontal distance between them constant. In this embodiment, the connecting member is a steel frame 406, which is bolted to the first slider 402 and the second slider 404 of the first and second conveying components, respectively.

[0029] The first conveyor line 100 is used to convey alternately placed PCB boards 500 and steel plates 600. The first conveyor line 100 is a roller conveyor 301 type. The second conveyor line 200 is used to convey the PCB boards 500. The second conveyor line 200 is a trolley type. The third conveyor line 300 is used to convey the steel plates 600. The third conveyor line 300 is a roller conveyor 301 type. The roller conveyor 301 type includes several rollers 301 with the same gap. A frame 302 is fixedly installed around the feed end of the roller conveyor 301 type. Several supports 303 are movably installed within the frame 302. The direction of movement of the supports 303 is perpendicular to the direction in which the steel plate 600 is conveyed by the roller 301 conveyor. This ensures that the top height of the supports 303 is higher than the initial height of the roller 301 when in its initial position. Specifically, a telescopic cylinder is installed within the frame 302, and the telescopic end of the cylinder is fixedly connected to the support 303. The support 303 has a cylindrical structure. In other embodiments, a rubber block is glued and fixed to the top of the support 303, i.e., the end that contacts the steel plate 600. Inclined baffles 304 are provided on both sides of the third conveyor line 300 along the conveying direction. Compression springs 305 for resetting the inclined baffles 304 are fixedly installed at the bottom of the inclined baffles 304.

[0030] The specific application process is as follows:

[0031] When using, such as Figure 1As shown, when the first transporter picks up the PCB board 500 and moves it to the second conveyor line 200, the second transporter can simultaneously pick up the steel plate 600 located on the first conveyor line 100. Similarly, when the first transporter returns above the first conveyor line 100 to pick up the PCB board 500, the second conveyor line 200 picks up the steel plate 600 and moves it to the third conveyor line 300 for placement. Through the coordinated operation of the first and second transporters, the entire disassembly process is smoother, reducing the time spent on multiple operations and significantly improving production efficiency. During the placement of the steel plate 600 onto the third conveyor line 300, a baffle restricts the position of the steel plate 600. If the steel plate 600 is accidentally placed on top of the baffle, the baffle will automatically return to a horizontal position under the weight of the steel plate 600, preventing the baffle end from scratching the steel plate 600. The third conveyor line 300 operates without stopping during production. Specifically, the steel plate 600 is first placed on the support 303, then the second conveyor component is released from fixing the support 303, and the support 303 is lowered so that the steel plate 600 contacts the roller 301. This avoids direct contact between the steel plate 600 and the running roller 301. If the steel plate 600 contacts the roller 301 before the second conveyor component is released from fixing it in time, the bottom panel of the steel plate 600 will be scratched, affecting the pressing quality of the new batch of PCB boards 500.

[0032] Example 2

[0033] The third conveyor line 300 is integrated into the first conveyor line 100. This design significantly reduces the overall space occupied by the equipment, making the production line layout more compact and efficient. By integrating the third conveyor line 300 into the first conveyor line 100, not only is additional installation space saved, but the connection and coordination between equipment are also simplified. For the reusable steel plate 600, the integrated design allows the steel plate 600 to return to the first conveyor line 100 more easily after completing a splitting and overlapping process, forming a closed-loop workflow. This seamless connection not only improves material flow efficiency but also reduces potential errors and time losses caused by complex handling paths.
