DETAILED DESCRIPTION

[0022] The following description is used to disclose the present application so that those skilled in the art can realize the preferred embodiments of the present application in the following description. Those skilled in the art can think of other obvious variants.

[0023] Example 1

[0024] Please refer to Figures 1-4 , the present application provides a kind of impregnated PCB board drying rack, including two columns 1, multiple support plates 2 are arranged in the intermediate position of two columns 1 and are used to limit the bearing mechanism of PCB board.

[0025] The bearing mechanism comprises a plurality of L-shaped connecting plates 5 arranged at one end of the support plate 2, a positioning assembly acting on the connecting plates 5, two symmetrically arranged clamping plates 8 arranged at one end of the connecting plates 5, a support groove 9 arranged in an L-shaped manner on the inner surface of the clamping plate 8, and an adjusting assembly acting on one of the clamping plates 8. The two clamping plates 8 at the end of the two connecting plates 5 at adjacent positions are arranged in a symmetrical manner.

[0026] When the PCB needs to be carried and dried, the spacing between the two adjacent connecting plates 5 can be adjusted by the positioning assembly, so that the spacing between the two groups of clamping plates 8 at the ends of the two adjacent connecting plates 5 can be adjusted, and the spacing between the two clamping plates 8 at the end of the connecting plate 5 can be adjusted by the adjusting assembly. Thus, the spacing between the four clamping plates 8 at the ends of the two adjacent connecting plates 5 can be adjusted, so that the four corners of the PCB can extend into the adjacent support groove 9, thereby enabling the PCB of different sizes to be carried and limited, and ensuring that most of the surface of the PCB is not blocked when it is dried.

[0027] Please refer to Figures 1-4 The adjusting assembly comprises a threaded rod 10 rotatably connected to the surface of the connecting plate 5, a threaded sleeve 12 threadedly connected to the outer surface of the threaded rod 10, and a limiting shaft 11 penetratingly arranged on the surface of the threaded sleeve 12. One end of the limiting shaft 11 is fixed to the surface of the adjacent connecting plate 5. One group of clamping plates 8 is fixed to the surface of the adjacent connecting plate 5, and the other group of clamping plates 8 is fixed to the surface of the adjacent threaded sleeve 12.

[0028] Since the limiting shaft 11 can limit the movement track of the threaded sleeve 12 to only move in the horizontal direction, when the spacing between the two clamping plates 8 at the end of the connecting plate 5 needs to be adjusted, the threaded sleeve 12 can be driven by the threaded structure between the threaded rod 10 to move the adjacent clamping plate 8 in the horizontal direction, thereby adjusting the spacing between the clamping plate 8 connected to the threaded sleeve 12 and the adjacent connecting plate 5, and thus being suitable for PCBs of different widths.

[0029] Please refer to Figures 1-4 The positioning assembly comprises a T-shaped positioning groove 3 arranged on the surface of one end of the support plate 2, and a plurality of limiting blocks 4 slidingly arranged in the positioning groove 3. One end of the limiting block 4 penetrates through the adjacent positioning groove 3 and is fixed to the inner surface of the adjacent connecting plate 5.

[0030] Due to the shape of the surface of the limiting block 4 and the inner cavity of the slide groove 3 and the resistance, the limiting block 4 can only slide in the inner cavity of the slide groove 3 at the adjacent position, so that the connecting plate 5 can only move in the horizontal direction, thereby adjusting the distance between the two adjacent connecting plates 5, and the PCB board of different width can be applied.

[0031] Please refer to Figures 1-4 The positioning assembly further comprises an iron plate 6 fixed to the top of the support plate 2 and an electromagnet 7 fixed to the inner surface of the connecting plate 5, and the surface of the bottom of the electromagnet 7 is in close contact with the surface of the adjacent iron plate 6.

[0032] When the connecting plate 5 slides in the horizontal direction, the electromagnet 7 can always slide in close contact with the surface of the iron plate 6, so that after adjusting the distance between the two adjacent connecting plates 5, the electromagnet 7 is turned on, and the connecting plate 5 is limited under the magnetic attraction between the support groove 9 and the adjacent iron plate 6, thereby stably carrying the PCB board.

[0033] Embodiment 2

[0034] Referring to Figures 1-4 The bearing mechanism further comprises a turnover assembly, and the turnover assembly comprises rotating shafts 13 fixed to the two sides of the support plate 2, and the rotating shaft 13 on the left side is in rotating connection with the surface of one of the groups of stand columns 1, and the rotating shaft 13 on the right side is in penetrating rotating connection with the other group of stand columns 1.

[0035] Due to the support of the rotating shaft 13 to the support plate 2, the support plate 2 can be rotated, so that the PCB board clamped and positioned by the four clamping plates 8 can be turned over, so that the surfaces of both ends of the PCB board can face the sun, thereby further ensuring the drying effect of the PCB board.

[0036] Referring to Figures 1-4 The turnover assembly comprises a circular gear 16 fixedly sleeved on the outer surface of one of the rotating shafts 13, a rack 17 meshingly arranged at one end of the circular gear 16, a fixed seat 14 fixed to the bottom of one side of one of the support plates 2, a hydraulic cylinder 15 fixed to the top of the fixed seat 14, a receiving plate 20 fixed to one side of the rack 17, a fixed shaft 21 fixed to the middle position of two adjacent receiving plates 20, and a guide component acting on the rack 17. The output end of the hydraulic cylinder 15 is fixed to the surface of the bottom of the adjacent receiving plate 20.

[0037] When the PCB needs to be turned over, the hydraulic cylinder 15 is started, so that the receiving plate 20 can move in the vertical direction under the connection of the plurality of fixed shafts 21, so that the plurality of racks 17 can move in the vertical direction, so that the adjacent position rotating shaft 13 can be rotated under the meshing action between the rack 17 and the gear 16, so that the support plate 2 can drive the supported PCB to turn over one hundred and eighty degrees. The guide component can further limit the movement trajectory of the rack 17 to make the movement more stable during the process.

[0038] Referring to Figures 1-4 The guide component includes a guide opening 18 opened on one side of the rack 17 and a guide strip 19 penetratingly arranged at the intermediate position of the plurality of guide openings 18, one side of the guide strip 19 being fixed with the surface of the adjacent position stand 1.

[0039] When the rack 17 moves in the vertical direction under the connection of the receiving plate 20, the inner wall of the guide opening 18 is resisted by the surface of the guide strip 19, so that the rack 17 can only move in the vertical direction more stably.
