Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to a pressing plate transfer fixture for circuit boards. Background Technology

[0002] In the fabrication of multilayer circuit boards, iron plates are used to press together to ensure that the copper layers are flatly attached to the resin board. These iron plates are usually stacked together. Due to the high flatness of the iron plates, air is expelled between the iron plates when they are stacked, forming negative pressure interlayer zones. These negative pressure interlayer zones can easily make it difficult to access the iron plates on the upper layers. Utility Model Content

[0003] This utility model provides a pressing plate transfer fixture for circuit boards, which solves the shortcomings of the prior art and solves the problem of difficulty in removing iron plates, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A circuit board pressing plate transfer fixture includes a horizontal plate with end plates perpendicularly provided at both ends along its length. A double-acting cylinder is installed on the lower wall of the horizontal plate by screws. A pair of push-pull rods are connected to each end of the double-acting cylinder. An end clamping plate is fixed to the outer end of the push-pull rod by a nut. A lower clamping plate is bent inward at the lower end of the end clamping plate. The double-acting cylinder can drive the end clamping plate to move inward, so that the lower clamping plate is located under the circuit board to support the circuit board and ensure the safety of the circuit board during transfer.

[0006] The inner wall of the end plate is fitted with a V-shaped plate by screws. Movable pull rods are threaded through both ends of the end plate. Magnets are installed at the lower ends of the movable pull rods. An upper plate is fixed to the upper end of the movable pull rods. The upper plate is located above the end plate. A vertical plate is welded onto the upper plate. An oblique hole is opened at the outer end of the vertical plate. The outer end of the oblique hole extends upward at an angle. A transverse hole is opened at the inner end of the oblique hole. A vertical end plate is welded to the outer end of the end plate. A guide rod is threaded onto the vertical end plate. An end cap is installed at the outer end of the guide rod. A movable end plate is fitted onto the guide rod. A concave plate is welded to the inner wall of the movable end plate. A movable rod is threaded onto the concave plate. The movable rod moves within the oblique hole and the transverse hole. A rectangular frame is installed at the inner end of the concave plate by screws. A pair of top wheels are rotatably installed within the rectangular frame. The top wheels are located on the inner and outer sides of the V-shaped plate. This solution uses magnets to attract the upper iron plate. When the end clamp moves inward, it moves the magnet upward, which in turn moves the attracted iron plate upward, placing it above the lower clamping plate. This magnetic attraction facilitates the separation of the top and next-layer iron plates. Furthermore, the lower clamping plate enhances safety during transfer, preventing the iron plate from falling.

[0007] Furthermore, the two ends of the end plate are provided with side plates that bend downwards, which can limit the iron plate when it is pulled upwards.

[0008] Furthermore, an end guide plate is welded to the lower wall of the end plate, and the push-pull rod passes through the end guide plate to limit and constrain the push-pull rod.

[0009] Furthermore, a lower extension tube is fitted onto the movable pull rod, and the upper end of the lower extension tube is welded to the lower wall of the end plate. When the magnet moves upward, the lower end of the lower extension tube pushes against the upper side of the iron plate, thereby separating the magnet from the iron plate.

[0010] Furthermore, the two ends of the moving rod are connected by threaded limit nuts, which are located on the outside of the concave plate, and limit the two ends of the moving rod by means of the limit nuts.

[0011] The advantages of the above technical solution are:

[0012] This invention facilitates the separation of iron plates and ensures the safety of the iron plates during transfer. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0014] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0015] Figure 2 A magnified view of point A is shown. Detailed Implementation

[0016] like Figures 1-2 As shown, a circuit board pressing plate transfer fixture is mounted on a three-dimensional moving system, which may be a three-axis robotic arm capable of moving in the X, Y, and Z directions. The fixture includes a horizontal plate 1 mounted to the three-dimensional moving system with screws. End plates 10 are perpendicularly positioned at both ends of the horizontal plate 1 along its length. Side plates 11 are bent downwards at both ends of the end plates 10. A bidirectional cylinder 2 is mounted to the lower wall of the horizontal plate 1 with screws. A pair of push-pull rods 20 are connected to each end of the bidirectional cylinder 2. An end clamping plate 3 is fixed to the outer end of each push-pull rod 20 with a nut. A lower clamping plate 30 is bent inwards at the lower end of the end clamping plate 3. An end guide plate 12 is welded to the lower wall of the end plate 10, and the push-pull rods 20 pass through the end guide plate 12.

[0017] A V-shaped plate 4 is installed on the inner wall of the end clamp 3 by screws. Movable pull rods are installed at both ends of the end plate 10. Magnets 56 are installed at the lower end of the movable pull rods. A lower extension tube 55 is sleeved on the movable pull rods. The upper end of the lower extension tube 55 is welded to the lower wall of the end plate 10. An upper plate 57 is fixed to the upper end of the movable pull rod. The upper plate 57 is located above the end plate 10. A vertical plate 58 is welded to the upper plate 57. An oblique hole 60 is opened at the outer end of the vertical plate 58. The outer end of the oblique hole 60 extends upward at an angle. A transverse hole 59 is opened at the inner end of the oblique hole 60. A vertical end plate 5 is welded to the outer end of the end plate 10. A guide rod 50 is threadedly connected to the vertical end plate 5. An end cap 51 is provided at the outer end of the guide rod 50. A movable end plate 52 is sleeved on the guide rod 50. A concave plate 53 is welded to the inner wall of the movable end plate 52. A movable rod 54 passes through the concave plate 53. The movable rod 54 moves within the oblique hole 60 and the transverse hole 59. Limit nuts are threadedly connected to both ends of the movable rod 54. The limit nuts are located outside the concave plate 53. A rectangular frame 61 is installed on the inner end of the concave plate 53 by screws. A pair of top wheels 62 are rotatably provided inside the rectangular frame 61, and the top wheels 62 are located on the inner and outer sides of the V-shaped plate 4.

[0018] In this embodiment, during operation, the fixture is moved to directly above the iron plate using a three-dimensional moving system. Then, the magnet 56 is pressed tightly against the upper iron plate using the three-dimensional moving system, so that the magnet 56 is attracted to the upper iron plate. Of course, the magnet 56 will also have a certain attraction to the lower iron plate. However, as the magnetic field strength weakens, the magnitude of the magnetic force generated by the magnet 56 is controlled to prevent it from attracting the lower iron plate.

[0019] Then, the bidirectional cylinder 2 is activated. Driven by the bidirectional cylinder 2, the lower clamping plate 3 moves inward. As the clamping plate 3 moves inward, the V-shaped plate 4 acts on the top wheel 62, causing the rectangular frame 61 and the concave plate 53 to move inward. The inward movement of the concave plate 53 drives the moving rod 54 to move inward. As the moving rod 54 moves inward, it acts on the oblique hole 60, causing the movable pull rod to move upward. As the movable pull rod moves upward, it drives the magnet 56 to move upward. As the magnet 56 moves upward, the upper iron plate and the lower iron plate are separated until they are separated. After that, the iron plate moves upward and passes through the lower clamping plate 30. The lower clamping plate 30 also moves inward with the bidirectional cylinder 2, thereby achieving the purpose of limiting the lower side of the iron plate to prevent the iron plate from falling during transfer.

[0020] Finally, the iron plate is transferred to the pressing position using a three-dimensional moving system. Then, the connection between magnet 56 and the iron plate is removed, and the iron plate moves downward and acts on the copper-clad layer.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
