[0002] At present, most of the PCB electroplating units on the market are equipped with a blow-drying device with a fixed air outlet and a moving rack. This blow-drying system is designed for fixed drying, which has blind spots and no change in the coverage area, resulting in poor drying effect. Moreover, for some units, the blow-drying device is installed on the cylinder for the rack to be raised and lowered. Due to the short time for the rack to be raised and lowered, the blow-drying device cannot dry the rack, resulting in water dripping from the rack. Summary of the invention

[0037] like Figure 1-Figure 11 As shown, the present invention provides a lifting and drying device, which is used to dry the rack 1, and the lifting and drying device includes:

[0038] A power assembly that can be raised and lowered relative to the rack 1;

[0039] The air duct 5 is connected to the power assembly and driven to move up and down by the power assembly. The air duct 5 is connected to a blower. The air duct 5 has an air outlet 51 , and the air outlet 51 faces the bracket 1 .

[0040] The scheme of the present invention utilizes power components such as cylinders 3 to drive the air outlet duct 5 to rise and fall, thereby increasing the blowing area; and the positive and negative groups of cylinders 3 are staggered (or simultaneously) lifted and lowered to shake off (or squeeze out) the water droplets on the rack 1; the rack 1 stays in the cylinder body longer than when it is lifted and lowered, thereby improving the water-removing effect. Compared with the prior art, the blow-drying system is designed to be fixedly blow-dried, with blind spots and no change in the coverage area. The scheme of the present application uses an air duct 5 that rises and falls, which can expand the blow-drying area and reduce the blind spots for blow-drying. In addition, because the wind knife swings, water can be more easily carried away through the air when there is a pressure difference.

[0041] Wherein, as an implementation method, the power assembly can be a cylinder 3 assembly or a power motor.

[0042] Taking the power component as an example of a cylinder 3 component, as an implementation mode, the cylinder 3 component includes two groups of cylinders 3, each group of cylinders 3 is connected to a group of air ducts 5, and the bracket 1 is placed between the two groups of cylinders 3.

[0043] The two groups of air cylinders 3 drive the two groups of air ducts 5 connected to each other to be staggered and lifted. In addition, as another embodiment, the two groups of air cylinders 3 drive the two groups of air ducts 5 connected to each other to be lifted and lifted simultaneously.

[0044] That is to say, there are two kinds of actions of cylinder 3: one is that cylinder 3 is lifted and lowered in a staggered manner: one side is at the highest, and the other side is at the lowest, and cross-blowing can throw out the water droplets; the other is that cylinder 3 can also be lifted and lowered at the same time to squeeze the water droplets downward.

[0045] The air outlet 51 is arranged downward or the air outlet 51 is arranged upward.

[0046] Specifically, Figure 7-11 As shown, the air duct 5 may include an upper tube, a lower tube and a side tube, the side tube is an air inlet tube 5, the side tube is connected to the blower, the upper tube and the lower tube are air outlet tubes 5, both are connected to the side tube, and the upper tube and the lower tube are both provided with the air outlet 51.

[0047] Among them, as an implementation method, the air outlet 51 is a V-shaped air outlet, which can reduce the air outlet area and increase the air outlet rate. The V-shaped air outlet 51 forms a wind knife, which rises and falls to form a swing. When there is a pressure difference, water is more easily carried away through the air.

[0048] Furthermore, the lifting and drying device also includes: a cylinder lock plate and a roller 7. The upper tube of the air duct 5 is welded with a bracket 1 81 for fixing the cylinder lock plate. The cylinder lock plate connects the cylinder 3 and the air duct 5 to facilitate the up and down lifting of the air duct 5. The side tube is welded with a bracket 2 82 for fixing the roller 7. The cylinder 3 is fixed to the cylinder edge 2. The cylinder edge 2 is welded with a cylinder edge limiting plate 6 for limiting the roller 7. The limiting roller 7 does not swing left and right to prevent the air duct 5 from deforming and hitting the bracket 1. The roller 7 contacts the cylinder edge limiting plate 6. The roller 7 replaces the air duct 5 to rub against the cylinder edge limiting plate 6, thereby reducing the wear of the air duct 5 due to friction. Among them, the cylinder can be a copper cylinder.

[0049] Furthermore, the lifting and drying device also includes: a telescopic hose 4, and the air duct 5 is connected to the blower through the telescopic hose 4. Specifically, the upper part of the air duct 5 is connected with a telescopic hose 4 for air intake of the air duct 5 to facilitate the up and down lifting of the air duct 5.

[0050] Furthermore, the lifting and drying device may be provided in multiple groups, and the water-removing effect may be improved by adding multiple groups of drying devices.

[0051] The working principle of the lifting and drying device of the present invention is as follows:

[0052] The air cylinder 3 is used to increase the blowing area; because the time when the hanger 1 stays in the copper cylinder is longer than the time when it is raised and lowered, it is equivalent to increasing the water-removing time; the positive and negative air cylinders 3 are raised and lowered alternately (or simultaneously) to throw away (or squeeze away) the water drops on the hanger 1; the hanger 1 stays in the cylinder body longer than the time when it is raised and lowered, thereby improving the water-removing effect.

[0053] The lifting and drying device proposed in the embodiment of the present invention is used to dry the rack 1, and the lifting and drying device includes: a power assembly that can be lifted relative to the rack 1; an air duct 5, the air duct 5 is connected to the power assembly, driven by the power assembly to lift up and down, the air duct 5 is connected to the blower, and the air duct 5 has an air outlet 51, and the air outlet 51 faces the rack 1. The scheme of the present invention uses a power assembly such as a cylinder 3 to drive the air outlet air duct 5 to lift up and down, thereby increasing the blowing area; and the positive and negative groups of cylinders 3 are staggered (or simultaneously) lifted and lowered to throw away (or squeeze away) the water droplets on the rack 1; the rack 1 stays in the cylinder body for a longer time than when it is lifted and lowered, thereby improving the water-repelling effect. Compared with the prior art, the drying system is designed to be fixed and dry, there will be blind spots, and the coverage area does not change. The present application scheme uses an air duct 5 that lifts up and down, which can expand the drying area and reduce the drying blind spots. In addition, because the wind knife swings, water is more easily carried away through the air when there is a pressure difference.

[0054] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
