Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production tools, in particular to a PCB board drying rack. Background Art

[0002] There are different processes such as copper plating and electroplating in the production process of PCB boards. Generally, after completing these chemical treatment processes, the PCB boards need to be taken out to dry them before moving on to the next process. During this drying process, on the one hand, it is necessary to ensure that the residual chemical components and debris need to be discharged regularly, and on the other hand, it is necessary to ensure that there are no scratches and abrasions on the surface of the PCB board to avoid adverse effects on the PCB board.

[0003] However, when a board is placed on an existing board rack for PCB boards, only the lower part of the circuit board can be inserted into the slot to contact and bear force. When the area of ​​the circuit board is large, the upper part of the circuit board is not stable enough, and there will be a certain degree of shaking when it is placed in the slot. When a variety of boards of different specifications and sizes are placed in the same board rack, the tops of two adjacent circuit boards may contact each other. The instability of the upper end of the circuit board will apply a part of the force to the adjacent circuit board, causing wear on the board surface and affecting the quality of the circuit board.

[0004] The patent application number CN2022229071166 discloses a drying rack for PCB boards, including a frame, at least two sets of mutually parallel side panels are erected on the frame, and the side panels are provided with a plurality of slots for inserting circuit boards, and the slots on different side panels correspond to each other; a support baffle is erected on the frame, and the support baffle is arranged between the two side panels, and a plurality of the support baffles are arranged at intervals along the direction of the side panels; the frame is provided with a plurality of liquid outlets, and a liquid receiving tank is provided at the bottom of the frame. Although the drying rack can complete the drying of PCB boards, due to the presence of many protrusions and recessed areas on the PCB board, chemical components and debris are easily accumulated in the recessed areas or at the junction of the protrusions and the PCB board. In the drying process of the application, the PCB board is always in a vertical placement state, which will cause some debris to be hindered by the protrusions on the PCB board during the downward flow, which will slow down the drying speed of the PCB board.

[0005] Therefore, a PCB board drying rack is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2 , the utility model provides a technical solution:

[0020] A PCB board drying rack comprises a bracket 101. A plurality of flipping mechanisms are arranged at intervals on the bracket 101. The execution end of any flipping mechanism is detachably connected to a PCB board 201. The flipping mechanism is used to flip the PCB board 201 so that the residue on the PCB board 201 can be discharged in time when the PCB board 201 is dried.

[0021] Specifically, any flipping mechanism includes a reciprocating mechanism and a flipping unit. The reciprocating mechanism includes a base 301 connected to the bracket 101, a slider 302 slidably connected to the base 301, and a hydraulic rod 303 connected to the slider 302. The extension direction of the hydraulic rod 303 is the same as the sliding direction of the slider 302. The flipping unit is connected to the slider 302. The PCB board 201 is detachably connected to the execution end of the flipping unit. In this embodiment, the actions of all hydraulic rods 303 can be controlled by the same control device. This control method is a prior art and will not be described in detail here. In other implementations of this embodiment, the movement of the slider 302 on the base 301 can also be achieved using a common screw nut mechanism.

[0022] Specifically, the flip unit includes a rotating shaft 304, a gear 305 and a rack 306. The rack 306 is arranged on the base 301, and the extension direction of the rack 306 is the same as the sliding direction of the slider 302. The rotating shaft 304 is arranged through the slider 302 and is rotatably connected to the slider 302. One end of the rotating shaft 304 is detachably connected to the PCB board 201, and the other end is connected to the gear 305, and the gear 305 is meshed with the rack 306. A common clip can be installed at one end of the rotating shaft 304 where the PCB board 201 is installed, so that the PCB board 201 can be temporarily installed on the rotating shaft 304, and the PCB board 201 can be easily removed after drying. In other implementations of this embodiment, a groove can also be designed at one end of the rotating shaft 304 where the PCB board 201 is installed. When installing, the PCB board 201 is first placed in the groove, and then the PCB board 201 is fixed in the groove using fasteners such as bolts, so that the PCB board 201 can also be temporarily fixed on the rotating shaft 304.

[0023] In order to collect the chemical components and debris flowing out from the PCB board 201, a collection tank 401 is installed at the bottom of the bracket 101. The chemical components and debris on the PCB board 201 can be discharged into the collection tank 401 during the drying process.

[0024] In order to facilitate the movement of the device, a plurality of running wheels 501 are installed at the bottom of the bracket 101 .

[0025] Working principle:

[0026] When the PCB boards 201 that have completed the chemical treatment process need to be dried, a plurality of PCB boards 201 are first mounted on the rotating shaft 304 and then dried. During the drying process, each hydraulic rod 303 can be controlled to extend and retract by a matching control device, so that the slider 302 can reciprocate on the base 301. During the reciprocating movement of the slider 302, due to the existence of the gear 305 and rack 306 mechanism, the rotating shaft 304 will rotate with the movement of the slider 302, thereby driving the PCB boards 201 to rotate, so as to accelerate the drying speed of the PCB boards 201.
