The repulsive force between the electromagnet and the permanent magnet drives the guide rod to move. The movement of the guide rod drives the pressure plate to move. The pressure plate drives the spring to move. The movement of the spring drives the protective plate to move. The protective plate aligns the circuit board with the inner wall of the placement box.

[0004] The aforementioned patent requires placing the circuit board into a placement box for positioning. Multiple placement boxes and corresponding positioning devices are set on the transmission belt, and each positioning device needs to be controlled independently. The overall structure is relatively complex and costly. At the same time, it imposes significant size restrictions on the circuit board and cannot position circuit boards that cannot be clamped by the protective plate, thus having certain limitations.

[0022] 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a conveying device for circuit board production, including a support frame 1, a controller 4, and a circuit board body 5. A conveying assembly 2 is movably installed on the inner side of the support frame 1, and a positioning assembly 3 is fixedly installed on the top of the support frame 1 above the conveying assembly 2. The controller 4 is fixedly installed on the outer side of the support frame 1. The conveying assembly 2 includes rollers 21 rotatably installed on the front and rear sides of the inner side of the support frame 1. A conveyor belt 22 is movably installed on the outer side of the rollers 21. Support bosses 25 are fixedly installed at equal intervals on the outer side of the conveyor belt 22, and the circuit board body 5 is placed on the top of the support bosses 25. The positioning assembly 3 includes a mounting frame 31 fixedly installed on the top of the support frame 1. Positioning electric cylinders 32 are fixedly installed on both the left and right sides of the mounting frame 31 for positioning. The inner side of each electric cylinder 32 is fixedly equipped with a pushing mechanism 33, and the top of the mounting frame 31 is fixedly equipped with a vision sensor 34 facing the conveyor belt 22. By tilting and clamping the circuit board body 5 from the rear end of the support frame 1 onto the support boss 25, the side of the circuit board body 5 abuts against the support boss 25 to ensure stable and spaced placement. It is conveyed as the conveyor belt 22 moves. The vision sensor 34 detects the circuit board body 5 passing on the lower conveyor belt 22 and controls the positioning electric cylinders 32 on both sides to push the pushing mechanism 33 to move inward to contact the side wall of the circuit board body 5 and push the circuit board body 5 to complete the positioning in the center position on the support boss 25. The structure is simpler and easier to use. The positioning and conveying of the circuit board body 5 are convenient.

[0024] The cross-section of the support boss 25 is set in a right-angled triangle. The hypotenuse of the support boss 25 is set opposite to the running direction of the conveyor belt 22 so that the circuit board body 5 can naturally fit its surface when placed at an angle, reducing the possibility of slippage. The top of the support boss 25 is specially treated to increase the coefficient of friction, prevent the circuit board body 5 from shifting during the conveying process, improve the overall reliability of the conveying, and has a simple structure. It effectively improves the positioning accuracy and facilitates the gripping of the circuit board body 5 by the robot arm.

[0025] A drive motor 23 is fixedly mounted on the outer side of the support frame 1. Synchronous pulleys 24 are fixedly mounted on the output shaft of the drive motor 23 and on the exterior of one of the rollers 21. A synchronous belt is movably mounted on the exterior of the synchronous pulleys 24. The drive motor 23 transmits power to the rollers 21 through the cooperation of the synchronous pulleys 24 and the synchronous belt, thereby driving the conveyor belt 22 to run smoothly. This ensures that the conveyor belt 22 maintains a stable speed during operation, preventing positional displacement of the circuit board body 5 due to speed fluctuations.

[0026] The pushing mechanism 33 is inclined to match the support boss 25. The conveying component 2 and the positioning component 3 are both electrically connected to the controller 4. The inclined setting of the pushing mechanism 33 enables it to accurately cooperate with the support boss 25, ensuring efficient positioning and adjustment during the conveying of the circuit board body 5. The controller 4 adopts a programmable PLC control processor, which can control the drive motor 23 and communicate with the vision sensor 34. Based on the image fed back by the vision sensor 34 and visual detection, it can monitor the position and passage of the circuit board body 5 on the conveyor belt 22 in real time, and coordinate the actions of each component according to preset instructions, thereby improving the automation level of the conveying process and reducing the need for manual intervention.

[0027] Please see Figure 4 and Figure 5 The pushing mechanism 33 includes a connecting frame 331 fixedly installed inside the positioning electric cylinder 32. A sliding column 332 is slidably connected inside the connecting frame 331. A movable plate 333 is fixedly connected inside the sliding column 332. A spring 334 is movably sleeved outside the sliding column 332, located between the connecting frame 331 and the movable plate 333. A limit plate 335 is fixedly connected to the outer side of the sliding column 332. A touch sensor 336 located outside the movable plate 333 is fixedly installed inside the connecting frame 331. The mechanism is moved by the positioning electric cylinders 32 on both sides... The inner extension pushes the movable plate 333 from both sides to push the circuit board body 5 to the center position on the support boss 25. The movable plate 333 drives the sliding column 332 to slide outward, and the compression spring 334 provides cushioning. The movable plate 333 moves outward to press the touch sensor 336. The touch sensor 336 is triggered to generate an electrical signal that is transmitted to the controller 4. After receiving the signal, the controller 4 controls the positioning electric cylinders 32 on both sides to perform a reset operation, thereby effectively ensuring positioning accuracy and avoiding damage to the circuit board body 5.

[0028] A soft pad 337 is fixedly installed on the inner side of the movable plate 333. The soft pad 337 is made of a material with high elasticity and wear resistance, which can effectively reduce the friction and impact of the movable plate 333 on the surface of the circuit board body 5 during the pushing process. The surface of the soft pad 337 is designed with anti-slip texture, which increases the stability when in contact with the circuit board body 5 and prevents displacement during the positioning process.

[0029] The limiting plate 335 is located on the outside of the connecting frame 331, and the touch sensor 336 is located in the center of the connecting frame 331, so that it can accurately sense the movement status of the movable plate 333 and provide timely feedback signals. The inner side of the connecting frame 331 is designed with a special groove to accommodate the touch sensor 336, thereby avoiding interference from the external environment.

[0030] Working principle: During use, the drive motor 23 drives the synchronous wheel 24 outside its output shaft to rotate. Through the synchronous belt, the synchronous wheel 24 outside the roller 21 drives the roller 21 to rotate, which in turn drives the conveyor belt 22 to move. The circuit board body 5 is tilted and clamped on the support boss 25 from the rear end of the support frame 1. The side of the circuit board body 5 is pressed against the side of the support boss 25 to ensure stable and spaced placement. The circuit board body 5 is transported with the movement of the conveyor belt 22.

[0031] The visual sensor 34 can detect the image on the conveyor belt 22 passing below and transmit the image to the controller 4. The controller 4 receives the image and judges whether the circuit board body 5 is placed on the support boss 25. If the circuit board body 5 is placed, the controller 4 controls the positioning electric cylinders 32 located on the left and right sides of the circuit board body 5 to push the pushing mechanism 33 inward. The pushing mechanism 33 contacts the side wall of the circuit board body 5 from both sides and pushes the circuit board body 5 to the center position on the support boss 25 to ensure accurate positioning.

[0032] When the circuit board body 5 is pushed and positioned by the inward movement of the pushing mechanism 33, after the soft pad 337 contacts the side wall of the circuit board body 5, the movable plate 333 is forced to slide the sliding column 332 outward as the positioning electric cylinders 32 on both sides extend inward. During the process, the spring 334 between the connecting frame 331 and the movable plate 333 provides buffering. The movable plate 333 moves outward and squeezes the button part inside the touch sensor 336 to generate a signal that is transmitted to the controller 4. After receiving the signal, the controller 4 controls the positioning electric cylinders 32 on both sides to reset.

[0033] Subsequently, the circuit board body 5 is moved to the front of the support frame 1 via the conveyor belt 22, and finally the robotic arm removes the circuit board body 5. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
