Description

Technical Field

[0001] This utility model relates to the field of control board electronic component insertion or surface mount technology, and in particular to a control board surface mount placement rack. Background Technology

[0002] The control board consists of a circuit board, electronic components inserted into and soldered onto the circuit board, and electronic components attached to and soldered onto the circuit board. In actual production, the size of the circuit board often changes due to design requirements. After the electronic components are fixed, the control board still needs to be assembled. Therefore, it is necessary to use a transfer cart for transfer. However, the current placement rack has the problem of being inconvenient to adjust according to the size of the circuit board. At present, in order to place circuit boards of different sizes, the circuit board is simply placed on the placement board without limiting its upper end. This method can improve the applicability of the placement rack, but the stability of the circuit board after placement is poor. During the transfer process, the shaking of the circuit board often affects the stability of the fixed electronic components, and may even cause the circuit board to fall off. Utility Model Content

[0003] This utility model provides a control board mounting rack to overcome the shortcomings of the prior art. It can be adjusted according to the size of the circuit board and ensures the stability of the circuit board after 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 control board mounting rack includes a base plate, at least three casters are welded to the lower wall of the base plate, four vertical plates are welded to the base plate, and vertical grooves are provided on both sides of the vertical plates.

[0006] Multiple concave parts are arranged at intervals along the vertical direction on the vertical plate at the same end. The concave parts at the same height are connected by screws to a partition plate. The upper and lower sides of the partition plate are respectively provided with slots.

[0007] Furthermore, the concave part is fixed to the vertical plate by screws.

[0008] Furthermore, a rectangular column is bolted to the outer wall of the concave part, a movable side plate is fitted on the rectangular column, a groove is formed with an opening on the lower side of the movable side plate, the rectangular column passes through the groove, and movable rods are threaded to both ends of the movable side plate.

[0009] The two ends of the concave part are respectively connected by a pair of guide pins through threads. Each pair of guide pins is fitted with a movable outer plate. An inner pressure block is fixed on the inner wall of the movable outer plate. The inner wall of the inner pressure block acts on the bottom of the vertical groove. An inner extension plate is welded on the outer wall of the movable outer plate. An inclined hole is opened on the inner extension plate. The upper end of the inclined hole extends outward at an angle. The moving rod passes through the inclined hole.

[0010] Furthermore, a rotating shaft is welded to the outer end of the rectangular column, a swing plate is rotatably mounted on the rotating shaft, a connecting shaft is rotatably mounted on the swing plate, and a pressure roller is mounted on the inner end of the connecting shaft. The outer circumference of the pressure roller acts on the upper wall of the movable side plate.

[0011] Furthermore, a gripping rod is welded to the upper end of the swing plate.

[0012] Furthermore, an arc-shaped plate is formed on the upper side of the movable side plate, the outer periphery of the pressure roller acts on the outer periphery of the arc-shaped plate, and the upper end of the arc-shaped plate is a horizontal plane.

[0013] The advantages of the above technical solution are:

[0014] After the circuit board is placed, the two adjacent placement partitions support the top and bottom ends of the circuit board, which can prevent the circuit board from shaking during the transfer process and thus avoid adverse effects on the electronic components on it. It also facilitates the adjustment of the spacing between the placement partitions, thereby enabling the placement and transfer of circuit boards of different sizes. Attached Figure Description

[0015] 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.

[0016] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0017] Figure 2 A magnified view of point A is shown. Detailed Implementation

[0018] like Figures 1-2 As shown, a control board mounting bracket includes a base plate 1. At least three casters 2 are welded to the lower wall of the base plate 1. Four vertical plates 3 are welded to the base plate 1, and vertical grooves 30 are formed on both sides of the vertical plates 3. Multiple concave parts 4 are spaced apart along the vertical direction on the vertical plates 3 at the same end. Placement partitions 42 are screwed between the concave parts 4 at the same height. The upper and lower sides of the placement partitions 42 are respectively provided with slots 41. Optionally, both ends of the slots 41 are beveled. This design avoids damage to the circuit board during insertion. The slots 41 can limit the upper and lower ends of the circuit board, limiting the circuit board by tightening it during positioning.

[0019] When placing the circuit board, the operator inserts the circuit board into each pair of slots 41 to limit the circuit board's position. During operation, the circuit board can first be placed on the lower placement partition 42, then the placement partition 42 can be moved downwards, and then the upper placement partition 42 can be moved downwards to fix the circuit board in place and prevent it from shaking during transfer.

[0020] In some embodiments, the concave member 4 is fixed to the vertical plate 3 by screws 40, which facilitates the adjustment of the spacing between the partitions 42.

[0021] In some other embodiments, the aforementioned method of fixing with screws 40 requires tightening multiple screws 40 to adjust the position of the partition 42 when adjusting its height. This method is cumbersome and can easily cause the partition 42 to tilt. Therefore, in this embodiment, a rectangular column 54 is bolted to the outer wall of the concave member 4. A movable side plate 55 is fitted onto the rectangular column 54. The lower side of the movable side plate 55 has an opening formed by a groove 56. The rectangular column 54 passes through the groove 56. The two ends of the movable side plate 55 are respectively connected to movable rods 63 by threads. The two ends of the concave part 4 are respectively connected by a pair of guide pins 5 by threads. Each pair of guide pins 5 is fitted with a movable outer plate 50. An inner pressure block 51 is fixed on the inner wall of the movable outer plate 50. The inner wall of the inner pressure block 51 acts on the bottom of the vertical groove 30. An inner extension plate 52 is welded to the outer wall of the movable outer plate 50. An inclined hole 53 is opened on the inner extension plate 52. The upper end of the inclined hole 53 extends outward at an angle. The movable rod 63 passes through the inclined hole 53. A rotating shaft 57 is welded to the outer end of the rectangular column 54. A swing plate 58 is rotatably mounted on the rotating shaft 57. A connecting shaft 61 is rotatably mounted on the swing plate 58. A pressure roller 60 is provided on the inner end of the connecting shaft 61. The outer periphery of the pressure roller 60 acts on the upper wall of the movable side plate 55. A holding rod 59 is welded to the upper end of the swing plate 58. An arc-shaped plate 62 is formed on the upper side of the movable side plate 55. The outer periphery of the pressure roller 60 acts on the outer periphery of the arc-shaped plate 62, and the upper end of the arc-shaped plate 62 is a horizontal plane.

[0022] In this embodiment, when adjusting the height of the partition 42, the pressure roller 60 is rotated outward to cancel the effect of the pressure roller 60 on the arc plate 62. Then, the height of the partition 42 is adjusted. After the adjustment is completed, the operator rotates the swing plate 58 by holding the lever 59. The rotation of the swing plate 58 will cause the outer periphery of the pressure roller 60 to act on the outer periphery of the arc plate 62, thereby causing the moving outer plate 50 to move downward. The downward movement of the moving outer plate 50 will cause the moving rod 63 on it to act on the inclined hole 53, thereby causing the inner wall of the inner pressure block 51 to act on the bottom of the vertical groove 30, thereby achieving the operation of locking the height of the partition 42.

[0023] 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.
