Description

Technical Field

[0001] This utility model relates to the field of cavity filter housing processing, and in particular to an electroplating device for surface treatment of cavity filters. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out specific frequencies or frequencies outside of a power supply line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency has been detected. Cavity filters are high-performance electronic filters widely used in radio frequency and microwave communication systems.

[0003] For example, the utility model disclosed in the authorization announcement number CN211311625U discloses an electroplating device for surface treatment of cavity filters. By setting a movable groove and a pulley inside the electroplating box, it can realize the movement of the anode tube, which facilitates the adjustment of the distance between the opposing anode tubes to meet the electroplating of cavity filters of different thicknesses. In addition, a filter screen is installed to collect the electroplating residue generated during the electroplating process, preventing it from falling directly to the bottom of the electroplating box and contaminating the box.

[0004] The existing technology still has the following problems when used:

[0005] When performing surface electroplating on cavity filters, immersing the entire filter housing in the electroplating solution will coat the entire filter housing with a layer of plating. Since the inner wall of the filter housing does not require plating to enhance aesthetics or various performance aspects, immersing the entire filter housing in the electroplating solution will increase the consumption of anode metal and increase the cost of electroplating. Utility Model Content

[0006] To overcome the shortcomings of the prior art, this utility model provides an electroplating device for surface treatment of cavity filters, which can solve the following technical problems: When performing surface electroplating on cavity filters, immersing the entire filter housing in the electroplating solution will cause the entire filter housing to be coated with a layer. Since the inner wall of the filter housing does not need a coating to enhance aesthetics or various performance, immersing the entire filter housing in the electroplating solution will increase the consumption of anode metal and increase the cost of electroplating.

[0007] To solve the above technical problems, this utility model provides the following technical solution: an electroplating device for surface treatment of cavity filters, comprising a support frame and a filter housing to be electroplated, wherein a liftable lifting plate is provided on the inner side of the support frame, two plastic air boxes are provided at the bottom of the lifting plate, rubber base plates are provided on both sides of the plastic air boxes, a limiting rubber frame is fixed on one side of the rubber base plate, four limiting rubber blocks are symmetrically arranged on the side of the rubber base plate, two rubber support strips are fixed on the side of the rubber base plate, multiple side rubber plugs are fixed on the opposite side of the two rubber support strips, a groove is opened in the middle of the rubber base plate, and air holes are opened on the side of the plastic air boxes.

[0008] As a preferred embodiment of this utility model, a lifting cylinder is symmetrically fixed on the top surface of the support frame, and a lifting plate is fixed on the telescopic end of the lifting cylinder.

[0009] As a preferred technical solution of this utility model, a through hole is provided at the center of the top surface of the support frame, a three-way pipe is provided in the through hole, and air intake connecting hoses are provided at both ends of the three-way pipe. The other end of the air intake connecting hose is connected to the plastic air box.

[0010] As a preferred embodiment of this utility model, an air plug is inserted into the inner side of the air hole, and a handle is fixed to the other side of the air plug.

[0011] As a preferred embodiment of this utility model, the outer dimensions of the filter housing to be electroplated are the same as the inner frame dimensions of the limiting rubber frame.

[0012] As a preferred embodiment of this utility model, an electroplating tank is provided on the inner side of the support frame.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] 1. By designing a limiting rubber block set on one side of the rubber base plate, the filter housing to be electroplated is positioned, and the filter housing to be electroplated is further limited by the rubber base plate. The holes on the filter housing to be electroplated are sealed by the side rubber plug fixed on the rubber support strip. By sucking out the air inside the plastic air box, the filter housing to be electroplated is adsorbed on one side of the rubber base plate. The filter housing to be electroplated is then immersed in the electroplating bath with the plastic air box for electroplating operation. This achieves electroplating only on the surface of the filter housing to be electroplated, saving electroplating materials.

[0015] 2. By designing an air plug inside the air hole, the air plug can block the air hole, preventing the electroplating solution from flowing into the interior of the plastic air box when the filter housing to be electroplated is not installed on that side. Attached Figure Description

Air holes 17 are provided on both sides of the plastic air box 7, located within the groove 15. When not in use, air plugs 13 are inserted into the air holes 17 to seal them. A handle 14 is provided on one side of the air plug 13 to facilitate removal of the air plug 13 from the air hole 17. A limiting rubber block 11 is symmetrically fixed on one side of the rubber base plate 8. The limiting rubber block 11 is inserted into the threaded hole of the filter housing 16 to be electroplated to position the filter housing 16. A limiting rubber frame 10 is fixed on one side of the rubber base plate 8, located at the edge of the rubber base plate 8. The rubber base plate 8 allows for... To further limit the position of the filter housing 16 to be electroplated, rubber support strips 9 are fixed to the side of the rubber base plate 8. Two rubber support strips 9 are provided, and side rubber plugs 12 are fixed to the opposite surfaces of the two rubber support strips 9.
