They offer a range of advantages, such as improving the performance of electronic devices, reducing costs, and saving space. Circuit board loading is an essential step in the circuit board manufacturing process. Circuit board loading refers to the process of mounting electronic components onto the circuit board. This requires placing the components in the appropriate positions, orientations, and directions before inserting them into the holes in the circuit board or directly soldering them to the surface of the circuit board.
[0003] A feeding device is needed in the circuit board production process. A search revealed a patent document with publication number CN220033024U that discloses a circuit board feeding device, comprising: a fixed frame, with a first roller and a second roller respectively engaged at both ends of the fixed frame; a first connecting piece connected to the outer side of the fixed frame; a second connecting piece connected to the inner side of the fixed frame; and a cover plate connected to the upper surface of the fixed frame; a clamping plate with a belt connected to its outer side. This application uses a vacuum suction cup to improve the material handling capacity of the equipment and a clamping sleeve to prevent circuit board displacement.
[0004] The aforementioned patent also has the following drawbacks: poor adaptability. The application uses two sets of symmetrically distributed clips to fix the circuit board, but the clips cannot be adjusted in spacing. When feeding circuit boards of different sizes, special corresponding clips need to be set up, which cannot meet production needs. Therefore, a circuit board feeding device is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a circuit board feeding device with advantages such as strong applicability and ease of unloading. It solves the problem that the spacing of the ferrule cannot be adjusted, and that special corresponding ferrules are required when feeding circuit boards of different sizes.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a circuit board feeding device, comprising a feeding structure mounted on a base for feeding circuit boards, wherein a material transfer structure is provided above the feeding structure;
[0007] The material transfer structure includes a telescopic electric cylinder and a suction plate fixed to the output end of the telescopic electric cylinder. The material transfer structure is provided with a fixing structure for fixing the circuit board, and the side wall of the suction plate is provided with a spreading structure for use with the fixing structure.
[0008] The fixing structure includes a mounting base, on which a fixed slide is slidably disposed; an abutment plate is fixed to one side of the fixed slide; and a guide member connected to the fixed slide is provided on the mounting base.
[0009] The abutment plate is inclined, and the spreading structure moves down via a telescopic electric cylinder to abut against the inclined surface of the abutment plate.
[0010] Furthermore, the material conveying structure includes a frame fixed to the upper surface of the machine base, a drive roller rotatably mounted on the inner side of the frame, and a conveyor belt drivenly mounted on the outer surface of the drive roller.
[0011] Furthermore, the mounting base is fixed to the outer surface of the conveyor belt by bolts, and a drive motor connected to the drive roller is fixed to the outside of the frame. There are several fixing structures, and the several fixing structures are equidistantly distributed on the outer surface of the conveyor belt.
[0012] Furthermore, the fixed slide is L-shaped and is slidably mounted on the mounting base, with a protective pad fixed on the side of the fixed slide away from the mounting base.
[0013] Furthermore, the guide includes a slider, and the mounting base has a groove inside. The slider is slidably connected to the groove, and one side of the slider is fixed to the outer wall of the fixed slide base.
[0014] Furthermore, the guide also includes a guide rod fixed inside the slide groove, the guide rod passing through the inside of the slider, and a return spring surrounding the guide rod is fixed between one side of the slider and the inner wall of the slide groove.
[0015] Furthermore, the spreading structure includes an electric telescopic rod fixed to the side wall of the suction plate, a mounting frame fixed to the output end of the electric telescopic rod, and a roller mounted on the inner bearing of the mounting frame, the roller abutting against the inclined surface of the abutment plate.
[0016] Compared with the prior art, the present invention provides a circuit board feeding device, which has the following beneficial effects:
[0017] 1. The circuit board feeding device has a fixed structure that uses a return spring and abutment plate to firmly fix the circuit board and prevent it from shifting or falling off during transportation. At the same time, the sliding design of the fixed slide, together with the installation of the return spring, can be adjusted according to circuit boards of different specifications and sizes, which has strong adaptability and can be widely used in various circuit board production lines.
[0018] 2. The circuit board feeding device uses a telescopic electric cylinder to drive the suction plate to descend. At this time, the roller contacts the inclined surface of the abutment plate, and the downward pressure is decomposed into a horizontal component, which pushes the fixed slide to move outward along the guide rod, releasing the clamping of the circuit board, so that the vacuum suction cup of the suction plate can pick up the circuit board.

[0024] 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.
[0025] Please see Figures 1 to 4 This embodiment of a circuit board feeding device includes a feeding structure 2 mounted on a base 1 for feeding circuit boards. The feeding structure 2 includes a frame 201 fixed to the upper surface of the base 1. A drive roller 202 is rotatably mounted on the inner side of the frame 201, and a conveyor belt 203 is drivenly mounted on the outer surface of the drive roller 202. Specifically, a drive motor connected to the drive roller 202 is fixed to the outside of the frame 201. There are two feeding structures 2, which are symmetrically distributed, and a drive shaft is provided between two adjacent drive rollers 202.
[0026] In this embodiment, a material transfer structure is provided above the material conveying structure 2. The material transfer structure includes a telescopic electric cylinder 3 and a suction plate 4 fixed to the output end of the telescopic electric cylinder 3. A vacuum suction cup is provided on the suction plate 4. Through the coordinated work of the telescopic electric cylinder 3 and the suction plate 4, the material transfer structure can quickly and accurately pick up and move the circuit board, significantly reducing manual intervention and thus greatly improving production efficiency. A fixing structure 5 for fixing the circuit board is provided on the material conveying structure 2. The fixing structure 5 includes a mounting base 501, a fixed slide 502 is slidably disposed on the mounting base 501, an abutment plate 503 is fixed on one side of the fixed slide 502, and a guide member connected to the fixed slide 502 is provided on the mounting base 501. Specifically, the mounting base 501 is fixed to the outer surface of the conveyor belt 203 by bolts. There are several fixing structures 5, and the several fixing structures 5 are equidistantly distributed on the outer surface of the conveyor belt 203. The fixed slide 502 is L-shaped and slidably mounted on the mounting base 501. A protective pad 508 is fixed to the side of the fixed slide 502 away from the mounting base 501. The protective pad 508 is made of silicone or polyurethane. It should be noted that the material transfer structure is connected to the linear module (not shown in the figure). The material transfer operation is achieved through the cooperation of the material transfer structure and the linear module.
[0027] To improve the moving stability of the fixed slide block 502, the guide component includes a slider 504. A groove 505 is formed inside the mounting base 501. The slider 504 is slidably connected to the groove 505, and one side of the slider 504 is fixed to the outer wall of the fixed slide block 502. The guide component also includes a guide rod 506 fixed inside the groove 505, which passes through the slider 504. A return spring 507 is fixed between one side of the slider 504 and the inner wall of the groove 505, surrounding the guide rod 506. The sliding connection between the slider 504 and the groove 505 reduces friction during the movement of the fixed slide block 502, while the guide rod 506 provides precise guidance, enabling the fixed slide block 502 to move stably along a predetermined path.
[0028] Furthermore, the design of the return spring 507 allows the fixed slide 502 to quickly return to its original position when subjected to external force, maintaining a stable clamping effect on the circuit board. Simultaneously, the return spring 507 also acts as a buffer, reducing the impact force on the circuit board during the fixing process and enhancing the reliability of the fixing structure 5.
[0029] To facilitate material unloading, a supporting structure 6 is provided on the side wall of the suction plate 4 to cooperate with the fixing structure 5. The supporting structure 6 includes an electric telescopic rod 601 fixed to the side wall of the suction plate 4. A mounting bracket 602 is fixed to the output end of the electric telescopic rod 601, and a roller 603 is mounted on the inner bearing of the mounting bracket 602. The supporting structure 6 reduces manual intervention through automated operation, enabling the circuit board to be released quickly and accurately during the unloading process, thereby improving production efficiency. Specifically, the abutment plate 503 is set at an angle. The roller 603 abuts against the inclined surface of the abutment plate 503, and the supporting structure 6 moves down through the telescopic electric cylinder 3 to abut against the inclined surface of the abutment plate 503. Through the cooperation between the roller 603 and the inclined surface of the abutment plate 503, the supporting structure 6 can smoothly open the fixed slide 502, avoiding damage to the circuit board due to excessive impact during the release process.
[0030] The working principle of the above embodiments is as follows:
[0031] The drive motor starts, which drives the conveyor belt 203 to move and transport the circuit board to the designated position. The telescopic electric cylinder 3 drives the suction plate 4 to move down and suck up the circuit board through suction. During the conveying process, the abutment plate 503 of the fixed structure 5 clamps the circuit board under the action of the return spring 507 to ensure the stability of the circuit board during the conveying process.
[0032] When the suction plate 4 picks up the circuit board and moves it to the designated position, the opening structure 6 moves down with the suction plate 4. During the downward movement, the roller 603 will first abut against the inclined surface of the abutment plate 503. As the suction plate 4 moves down, the fixed slide 502 is opened, releasing the circuit board and facilitating the feeding operation of the suction plate 4.
[0033] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.
[0034] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
