Description

Technical Field

[0001] This utility model relates to the field of control board processing technology, and in particular to a placement rack. Background Technology

[0002] During the manufacturing process of control boards, operations such as soldering electronic components are required. After soldering, the control boards also need to be tested and coated with conformal coating. When transferring control boards with soldered electronic components, they are often stacked with a foam pad between each board to prevent damage or detachment of electronic components during transfer. However, this placement method results in poor stability of the control boards during transfer, and it is also inconvenient to place some long and narrow control boards in this way. Utility Model Content

[0003] This utility model provides a placement rack to overcome the shortcomings of the prior art and solve the problem that electronic components are easily damaged when the control board is placed, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A placement rack includes a rectangular back plate with multiple pairs of guide holes arranged in an equally spaced array along its length direction and parallel to each other in its width direction. Multiple pairs of adjustment components are arranged in an equally spaced array along the length direction of the back plate. The adjustment components are movable along the length direction of the guide holes. Each adjustment component has a pair of concave parts, which are distributed vertically. Multiple rollers are rotatably arranged inside the concave parts via axles. The rollers are located inside the concave parts.

[0005] Furthermore, the adjusting component includes a vertically arranged movable plate, with a connecting block formed on the inner side of the movable plate. A pair of connecting rods are threadedly connected to the connecting block, and the connecting rods pass through guide transverse holes. An end block is threadedly connected to the other end of the connecting rod. A groove is provided at one end of the end block, and a rotating top block with an elongated structure is rotatably arranged in the groove. An inner top plate is fitted on the connecting rod, and the inner end of the rotating top block can abut against the outer wall of the inner top plate. A spring is fitted on the connecting rod, and the inner end of the spring abuts against the inner wall of the inner top plate and the inner end of the spring abuts against the back plate.

[0006] Furthermore, a holding plate is formed on the outer end of the rotating top block.

[0007] Furthermore, the inner end of the spring abuts against a collar, which is fitted onto the connecting rod, and the inner wall of the collar abuts against the back plate.

[0008] Furthermore, a side plate is formed on the movable plate.

[0009] Furthermore, a connecting protrusion is formed on the inner end of the concave part. The connecting protrusion on the lower concave part is fixed to the lower end of the movable plate by screws. A vertical hole is opened at the upper end of the movable plate. A pull rod is threadedly connected to the connecting protrusion on the upper concave part. The pull rod passes through the vertical hole. An inner pressure plate is sleeved on the pull rod. The inner pressure plate abuts against the inner wall of the movable plate. An end plate is fixed to the inner end of the pull rod by a fixing screw perpendicular to its axis. A pair of V-shaped spring pieces are welded on the end plate. The arc-shaped section of the spring pieces abuts against the outer wall of the inner pressure plate.

[0010] The advantages of the above technical solution are: This invention uses two pairs of concave parts to constrain and limit the control board, preventing contact between the control boards and thus avoiding damage to electronic components. The rollers facilitate the insertion of the control board between the two pairs of concave parts.

[0011] In addition, the spacing between the two pairs of concave parts can be adjusted to accommodate the placement of control boards of different widths, thereby expanding the applicability range.

[0012] Furthermore, in order to facilitate the placement and positioning of control boards of different thicknesses, the spacing between each pair of concave parts is adjustable. Attached Figure Description

[0017] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0018] like Figures 1-4As shown, a placement rack includes a rectangular back plate 1. Optionally, a placement lower plate perpendicular to the back plate 1 can be welded to the lower end of the back plate 1. The back plate 1 has multiple pairs of guide holes 10 arranged in an equally spaced array along its length direction and parallel to each other in its width direction. The back plate 1 has multiple pairs of adjusting components arranged in an equally spaced array along its length direction. The adjusting components are movable along the length direction of the guide holes 10. Each adjusting component has a pair of concave parts 26, which are distributed vertically. Multiple rollers 28 are rotatably arranged inside the concave parts 26 via a wheel axle 27. The rollers 28 are located inside the concave parts 26.

[0019] The adjusting component includes a vertically arranged movable plate 20. A connecting block 19 is formed on the inner side of the movable plate 20. A pair of connecting rods 11 are threaded onto the connecting block 19. The connecting rods 11 pass through guide holes 10. The other end of the connecting rods 11 is threaded onto an end block 12. One end of the end block 12 has a groove. A long, rectangular rotating top block 14 is rotatably mounted in the groove. A holding plate 15 is formed on the outer end of the rotating top block 14. An inner top plate 16 is fitted onto the connecting rods 11. The inner end of the rotating top block 14 abuts against the outer wall of the inner top plate 16. A spring 18 is fitted onto the connecting rods 11. The inner end of the spring 18 abuts against the inner wall of the inner top plate 16 and against the back plate 1. Optionally, a collar 17 abuts against the inner end of the spring 18. The collar 17 is fitted onto the connecting rods 11, and its inner wall abuts against the back plate 1.

[0020] Optionally, a side plate 29 is formed on the movable plate 20.

[0021] The inner end of the concave part 26 is formed with a connecting protrusion 25. The connecting protrusion 25 on the lower end of the concave part 26 is fixed to the lower end of the movable plate 20 by screws 22. The upper end of the movable plate 20 is provided with a vertical hole 21. The connecting protrusion 25 on the upper end of the concave part 26 is connected to a pull rod 23 by threads. The pull rod 23 passes through the vertical hole 21. An inner pressure plate 30 is sleeved on the pull rod 23. The inner pressure plate 30 abuts against the inner wall of the movable plate 20. The inner end of the pull rod 23 is fixed with an end plate 31 by a fixing screw perpendicular to its axis. A pair of V-shaped spring pieces 32 are welded on the end plate 31. The arc-shaped section of the spring piece 32 abuts against the outer wall of the inner pressure plate 30.

[0022] In this embodiment, when placing the control board, the spacing between every two pairs of concave parts 26 needs to be adjusted according to the width of the control board. During the adjustment operation: the operator first rotates the inner end of the rotating top block 14 upward so that the rotating top block 14 cancels the force on the inner top plate 16. Then, the inner top plate 16 will move outward under the action of the spring 18, while the spring 18 is in a naturally extended state. Then, the moving plate 20 is adjusted at the position of the guide horizontal hole 10 as needed. After the adjustment is completed, the operator rotates the inner end of the rotating top block 14 downward so that the inner end of the rotating top block 14 acts on the outer wall of the inner top plate 16, and the spring 18 is in a compressed state, and the inner wall of the collar 17 abuts against the back plate 1.

[0023] The operator then inserts the control board between each pair of concave parts 26. After insertion, the side plate 29 limits and constrains both sides of the control board. The operator then pushes the inner pressure plate 30 outward and moves the upper concave part 26 downward so that the upper roller 28 abuts against the blank area of ​​the control board, that is, the area on the control board where no electronic components are installed. Then the operator releases the pushing force on the inner pressure plate 30 so that it abuts against the inner wall of the moving plate 20 again under the action of the spring piece 32.

[0024] After constraints are imposed, the control board transfer operation is performed.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
