Description

Technical Field

[0001] This utility model belongs to the field of PCB board manufacturing technology, and in particular relates to a belt-type telescopic PCB board transfer table. Background Technology

[0002] A PCB conveyor, also known as a docking station, is a specialized conveying device used in SMT surface mount technology production lines to connect, buffer, and transfer PCB boards. It is usually located between main production equipment or at the entrance. The PCB conveyor can act as a bridge to connect production equipment with different heights, speeds, or interfaces, ensuring that PCB boards can flow smoothly between equipment.

[0003] Since the main function of the board conveyor is to connect and transport, the placement of the board conveyor depends entirely on the distance between the two production machines. If the distance between the two production machines is large, multiple board conveyors need to be placed, which increases costs. In addition, since multiple board conveyors need to be controlled separately, synchronization problems may be encountered, resulting in a smooth transmission process and affecting the normal production of PCB boards.

[0004] To address these issues, we propose a belt-driven, retractable PCB conveyor system. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a belt-type retractable PCB board transfer platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A belt-driven telescopic PCB conveyor includes a frame, with a base plate and a top plate fixedly installed inside the frame. Two connecting platforms are installed between the base plate and the top plate. The connecting platform closer to the top plate is the first connecting platform, and the connecting platform closer to the base plate is the second connecting platform. A stepper motor for lifting the first connecting platform is installed on the top of the top plate, and a servo motor for pushing the second connecting platform is installed on the top of the base plate. An extension frame is provided on the side wall of the frame. The extension frame and the base plate are provided with two parallel motion tracks. A slider is slidably connected to each motion track, and the tops of the two sliders are fixedly connected to the bottom of the second connecting platform.

[0008] Preferably, the output end of the stepper motor passes through the top plate and is fixedly connected to a lifting frame, and the first connecting platform is located inside the lifting frame.

[0009] Preferably, a plurality of limiting rods are fixedly provided on the top of the lifting frame, and a plurality of limiting seats are provided on the side wall of the top plate, with the plurality of limiting rods passing through the plurality of limiting seats respectively.

[0010] Preferably, the output end of the servo motor is fixedly provided with a drive wheel, the top of the base plate is provided with a rotating wheel, the drive wheel and the rotating wheel are driven by a belt, a fixing clamp is fixedly provided on the side wall of the belt, a fixing block is fixedly provided on the side wall of the fixing clamp, the fixing block is fixedly provided at the bottom of the second connecting platform, and the fixing block is located in the middle position of the two sliders.

[0011] Preferably, baffles are provided at both ends of the motion track, and the height of the baffles is greater than the height of the slider.

[0012] Preferably, the thickness of the bottom of the lifting frame is the same as the thickness of the slider, and the height of the servo motor is less than the height of the motion track.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] This application sets up a movable first docking platform and a second docking platform in the frame. The first docking platform is driven to move longitudinally by a stepper motor, and the second docking platform is driven to move laterally by a servo motor. When the length needs to be changed, the first docking platform can be lowered to a position where it is raised above the second docking platform, thereby achieving the effect of long-distance transmission. If long-distance transmission is not required, the first docking platform can be raised to a higher position, and transmission can be carried out solely through the second docking platform, thus adapting to more application scenarios.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-4 As shown, a belt-driven telescopic PCB conveyor includes a frame 1. A base plate 2 and a top plate 3 are fixedly installed inside the frame 1. Two connecting platforms are installed between the base plate 2 and the top plate 3. The connecting platform closer to the top plate 3 is the first connecting platform 4, and the connecting platform closer to the base plate 2 is the second connecting platform 5. The first connecting platform 4 and the second connecting platform 5 are completely identical except for their positions. A stepper motor 6 for lifting the first connecting platform 4 is installed on the top of the top plate 3. The output end of the stepper motor 6 passes through the top plate 3 and is fixedly connected to a lifting frame 11. The first connecting platform 4 is located inside the lifting frame 11. The lifting frame 11 is a frame structure, which can achieve the effect of lifting the first connecting platform 4 while saving costs.

[0022] A number of limiting rods 12 are fixedly installed on the top of the lifting frame 11, and a number of limiting seats 13 are opened on the side wall of the top plate 3. The limiting rods 12 pass through the limiting seats 13 respectively. The setting of the limiting rods 12 and the limiting seats 13 will limit the lifting frame 11, thereby ensuring that the lifting frame 11 can stably drive the first connecting platform 4 to rise and fall. Moreover, the length of the limiting rods 12 can also be guaranteed. When the first connecting platform 4 is completely lowered onto the motion track 9, the limiting rods 12 are still limited by the limiting seats 13.

[0023] An extension frame 8 is provided on the side wall of the platform 1. The extension frame 8 and the base plate 2 are provided with two parallel motion tracks 9. A slider 10 is slidably connected to each motion track 9. The tops of the two sliders 10 are fixedly connected to the bottom of the second docking platform 5. The sliders 10 make the second docking platform 5 move more smoothly. At the same time, the extension frame 8 increases the movement distance of the second docking platform 5, which makes it easier to make way for the first docking platform 4. A baffle 19 is provided at both ends of the motion track 9. The height of the baffle 19 is greater than the height of the slider 10. The baffle 19 can prevent the slider 10 from breaking through the position of the motion track 9.

[0024] A servo motor 7 for pushing the second docking platform 5 is installed on the top of the base plate 2. A drive wheel 14 is fixedly installed at the output end of the servo motor 7. A rotating wheel 15 is installed on the top of the base plate 2. The drive wheel 14 and the rotating wheel 15 are driven by a belt 16. A fixing clamp 17 is fixedly installed on the side wall of the belt 16. A fixing block 18 is fixedly installed on the side wall of the fixing clamp 17. The fixing block 18 is fixedly installed at the bottom of the second docking platform 5. The fixing block 18 is located in the middle of the two sliders 10. When the servo motor 7 drives the drive wheel 14 to rotate, the rotating wheel 15 will rotate together under the drive of the belt 16. The fixing clamp 17 fixed on the side wall of the belt 16 will drive the fixing block 18 and the second docking platform 5 to move laterally along the motion track 9.

[0025] The thickness of the bottom of the lifting frame 11 is the same as the thickness of the slider 10. At the same time, the height of the servo motor 7 is less than the height of the motion track 9. This allows the first docking platform 4 to be placed on the motion track 9 and then be at the same height as the second docking platform 5, thus ensuring the stable transmission of the PCB board.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
