Description
Technical Field
[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board stacking device. Background Technology
[0002] After the circuit boards are manufactured, they need to be tested to ensure their electrical connections are secure. During testing, the circuit boards are stacked on an automatic feeder, and the testing is performed automatically by the feeder on the testing device. However, during transfer, a trolley is used to move the circuit boards to the automatic feeder, and then they are placed stack by stack. This method cannot guarantee that the circuit boards are neatly stacked, and if they are not neatly stacked, it will affect subsequent testing operations. Utility Model Content
[0003] This utility model provides a circuit board stacking device to overcome the shortcomings of the prior art, making it easier to transfer stacked circuit boards and ensuring that the circuit boards can be stacked neatly during placement, thus having 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 transfer device includes a pair of concave plates. The lower end of the vertical section of the concave plates is threadedly connected to a pair of limiting screws. An L-shaped plate is fitted onto the limiting screws. A pair of strip holes are formed on the vertical section of the L-shaped plate. The limiting screws pass through the strip holes. A pull plate is formed at the lower end of the L-shaped plate. A movable rod is rotatably provided at the lower end of the pull plate. A pair of guide rods are threadedly connected to the lower end of the vertical section of the concave plates. An inner pressure plate is movably provided on the guide rods. A pair of side plates are formed on both sides of the inner pressure plate. An oblique hole is formed on the side plate. The upper end of the oblique hole extends outward at an angle. The movable rod passes through the oblique hole. An outer top spring is fitted onto the guide rod. The outer top spring is located between the inner pressure plate and the vertical section of the concave plate. A limiting insert is welded to the inner wall of the inner pressure plate. The limiting insert is inserted into the lower end of the vertical section of the concave plate.
[0006] A vertical rod is threadedly connected to the L-shaped plate, and an I-shaped plate is threadedly connected to the upper end of the vertical rod. A rectangular opening is provided on the I-shaped plate, and a rotating pressure plate is rotatably mounted inside the rectangular opening. End shafts are welded to both sides of the rotating pressure plate, and connecting protrusions are rotatably mounted on the end shafts. The lower end of the connecting protrusions is welded to the I-shaped plate. A connecting middle plate is welded between the transverse sections of the concave plate, and the lower end of the rotating pressure plate acts on the upper wall of the connecting middle plate.
[0007] Furthermore, the inner end of the limiting plate has a wedge-shaped structure.
[0008] Furthermore, a pair of lugs are welded to the upper end of the vertical section of the concave plate, and the vertical rod passes through the lugs.
[0009] Furthermore, a limit plate is welded to the upper wall of the connecting plate.
[0010] Furthermore, a guide block is installed on the transverse section of the concave plate by screws. A movable plate is fitted on the guide block. The outer end of the movable plate is bent downward to form a side arm plate. The lower end of the side arm plate is bent inward to form a lower pad plate. A rectangular window is opened on the movable plate. The guide block passes through the rectangular window. A pair of movable rods are fitted on the guide block. The outer end of the movable rod is provided with an end cap. A restoring spring is fitted on the movable rod. The restoring spring is located between the end cap and the guide block. The inner end of the movable rod is connected to an inner top vertical plate by threads. A rotating shaft is welded to the upper end of the guide block. A rotating top plate is rotatably mounted on the rotating shaft. The inner end of the rotating top plate acts on the outer wall of the inner top vertical plate. A second nut is connected to the upper end of the rotating shaft by threads. The second nut is located on the upper side of the rotating top plate.
[0011] Furthermore, an oblong hole is provided on the outer end of the rotating top plate, and an action vertical rod is inserted through the oblong hole. The upper end of the action vertical rod is connected to a concave pull plate by a thread. A connecting screw is rotatably provided on the concave pull plate.

[0012] The advantages of the above technical solution are:
[0013] This invention constrains both sides of the circuit board by using the vertical sections of two pairs of concave plates and limits the two ends of the circuit board by using side arm plates, so as to ensure that the circuit boards can be stacked neatly when placed.
[0014] This invention uses a limiting insert plate to support the circuit board located at the lower end, thereby ensuring the safety of the circuit board during transfer. Furthermore, its pull-out mechanism allows for easy placement of a concave plate onto stacked circuit boards, facilitating clamping operations during transfer.

[0021] Figure 5 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation
[0022] like Figures 1-5 As shown, a circuit board stacking device includes a pair of concave plates 1. A pair of limiting screws 10 are threadedly connected to the lower end of the vertical section of the concave plates 1. An L-shaped plate 11 is fitted onto the limiting screws 10. A pair of strip holes 12 are formed on the vertical section of the L-shaped plate 11, through which the limiting screws 10 pass. A pull plate 14 is formed at the lower end of the L-shaped plate 11. A movable rod 15 is rotatably mounted on the lower end of the pull plate 14. A pair of guide rods 16 are threadedly connected to the lower end of the vertical section of the concave plates 1. An inner pressure plate 18 is movably mounted on the guide rods 16. A pair of side plates 19 are formed on both sides of the inner pressure plate 18. An oblique hole 20 is formed on the side plate 19. The upper end of the hole 20 extends outward at an angle. The movable rod 15 passes through the inclined hole 20. When the movable rod moves upward, it will act on the inclined hole 20, thereby causing the inner pressure plate 18 to move inward. An outer top spring 17 is sleeved on the guide rod 16. The outer top spring 17 is located between the inner pressure plate 18 and the vertical section of the concave plate 1. When the outer top spring 17 loses the force of the inner pressure, it can cause the inner pressure plate 18 to move outward, thereby pulling out the limiting insert plate 21 welded on the inner pressure plate 18. The inner end of the limiting insert plate 21 has a wedge-shaped structure. The wedge-shaped structure facilitates the insertion of the limiting insert plate 21. The limiting insert plate 21 is inserted at the lower end of the vertical section of the concave plate 1.
[0023] A vertical rod 24 is threadedly connected to the L-shaped plate 11. A pair of lugs 22 are welded to the upper end of the vertical section of the concave plate 1. The vertical rod 24 passes through the lugs 22 to guide its movement. An I-shaped plate 25 is threadedly connected to the upper end of the vertical rod 24. A rectangular opening 26 is provided on the I-shaped plate 25. A rotating pressure plate 28 is rotatably mounted inside the rectangular opening 26. End shafts are welded to both sides of the rotating pressure plate 28. A connecting protrusion 27 is rotatably mounted on the end shaft. The lower end of the connecting protrusion 27 is welded to the I-shaped plate 25. On the I-shaped plate 25, a connecting middle plate 23 is welded between the transverse sections of the concave plate 1. The lower end of the rotating pressure plate 28 acts on the upper wall of the connecting middle plate 23, thereby increasing the distance between the I-shaped plate 25 and the connecting middle plate 23. As the distance between the two increases, the limiting plate 21 will move inward and limit the circuit board. A limiting plate 29 is welded on the upper wall of the connecting middle plate 23. The limiting plate 29 can limit the rotating pressure plate 28, thereby ensuring the safety of the circuit board during transfer.
[0024] In this embodiment, during circuit board transfer, the operator places the concave plate 1 onto the stacked circuit boards, ensuring the limiting insert 21 is positioned below the bottom circuit board. Then, the rotating pressure plate 28 is rotated. This rotation causes the I-shaped plate 25 to move upwards, which in turn moves the vertical rod 24 upwards. This vertical rod pulls the L-shaped plate 11 upwards, which in turn acts on the oblique hole 20 via the movable rod 15. This causes the limiting insert 21 to move inwards and be inserted below the bottom circuit board, at which point the outer top spring 17 is compressed. Thus, the vertical section of the concave plate 1 constrains the two sides of the circuit board, ensuring alignment. This ensures neat stacking of the circuit boards when placed on the automatic feeder. Furthermore, this device can transfer multiple circuit boards simultaneously, thus improving the efficiency of circuit board transfer.
[0025] In some embodiments, a guide block 30 is screwed onto the transverse section of the concave plate 1. A movable plate 31 is fitted onto the guide block 30. The outer end of the movable plate 31 is bent downward to form a side arm plate 9. When the side arm plate 9 approaches the two ends of the circuit board, it can align the two ends of the circuit board. The lower end of the side arm plate 9 is bent inward to form a lower pad plate 46. A rectangular window 32 is opened on the movable plate 31. The guide block 30 passes through the rectangular window 32 to guide the movement of the movable plate 31. A pair of movable rods are threaded onto the guide block 30. An end cap 34 is provided on the outer end of the movable rod. A return spring 35 is fitted onto the movable rod. The return spring 35 is located between the end cap 34 and the guide block 30. An inner top vertical plate 33 is threaded to the inner end of the movable rod. A rotating shaft 36 is welded to the upper end of 30. A rotating top plate 38 is rotatably mounted on the rotating shaft 36. The inner end of the rotating top plate 38 acts on the outer wall of the inner top vertical plate 33. A second nut 37 is threadedly connected to the upper end of the rotating shaft 36. The second nut 37 is located on the upper side of the rotating top plate 38. When the rotating top plate 38 rotates, its inner end will act on the inner top vertical plate 33, thereby causing the side arm plate 9 to move closer to both ends of the circuit board, so as to constrain both ends of the circuit board through the side arm plate 9.
[0026] An oblong hole 39 is provided on the outer end of the rotating top plate 38. An action vertical rod 40 is inserted through the oblong hole 39. The upper end of the action vertical rod 40 is connected to a concave pull plate 41 by a thread. A connecting screw 44 is rotatably provided on the concave pull plate 41. The lower end of the connecting screw 44 is connected to an inner top rotating plate 45 by a thread. An inward pushing L-shaped plate 90 is formed on one side of the connecting middle plate 23. A pair of guide crossbars 43 are welded on the inward pushing L-shaped plate 90. A guide sleeve 42 is sleeved on the guide crossbars 43. The guide sleeve 42 is welded to the concave pull plate 41. The inner end of the inner top rotating plate 45 acts on the outer wall of the inward pushing L-shaped plate 90. When the inner top rotating plate 45 rotates, its inner end will act on the inward pushing L-shaped plate 90, thereby causing the concave pull plate 41 to move outward. The movement of the concave pull plate 41 causes the rotating top plate 38 to rotate, thus ensuring the limiting effect of the side arm plate 9 on both ends of the circuit board.
[0027] When using this embodiment to limit the two ends of the circuit board, the operator rotates the inner top rotating plate 45. When the inner top rotating plate 45 rotates, the concave pull plate 41 will move outward. The outward movement of the concave pull plate 41 will cause the vertical rods 40 at both ends to act on the waist-shaped hole 39, thereby causing the two rotating top plates 38 to rotate synchronously. As the rotating top plates 38 rotate, the side arm plate 9 will limit the two ends of the circuit board.
[0028] 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.
