Description

Technical Field

[0001] The utility model relates to the technical field of circuit board etching, in particular to a filter rotary disc for printed circuit board etching. Background Art

[0002] Circuit etching is a critical step in forming conductive paths in PCB manufacturing. During this process, unwanted portions of copper foil are removed using a specific etching solution, leaving behind the desired conductor pattern. This method is not only highly efficient but also allows for precise control of the conductor shape and size, thus meeting the demands of electronic products for fine conductors and complex circuit designs. After etching, the etching liquid needs to be filtered and recycled, requiring specialized filtration equipment. Existing filter turntables often use oil-absorbing cotton pads to filter oil and suspended impurities from the etching liquid. After filtering a certain volume of etching liquid, the oil-absorbing cotton pads will absorb a certain amount of oil and suspended impurities, necessitating replacement of the oil-absorbing cotton pads.

[0003] For example, Chinese patent publication number CN214960338U discloses a filter turntable for etching printed circuit boards, including a box body, the lower surface of the box body is fixedly connected to support legs at the four corners, the upper surface of the box body is provided with a first through groove, and the inner side of the first through groove is fixedly connected to a frame, both ends of the frame are fixedly connected to first connecting blocks, the upper surfaces of the two first connecting blocks are fixedly connected to convenient lifting blocks, the inner side of the frame is fixedly connected to a support fence, and both side surfaces of the box body are provided with first grooves.

[0004] In order to protect their hands, workers need to use gloves to complete the replacement operation, but wearing rubber gloves will affect the efficiency of workers in replacing oil-absorbing cotton pads. Rubber gloves reduce the touch and sensitivity of fingers, making it impossible for workers to fix new oil-absorbing cotton pads as accurately as bare hands. When adjusting the position of the oil-absorbing cotton pad, the resistance brought by rubber gloves makes it clumsy, which slows down the pace of the entire replacement process and reduces the efficiency of replacing oil-absorbing cotton pads. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that production workers need to use gloves to complete the replacement operation in order to protect their hands, but wearing rubber gloves will affect the efficiency of workers in replacing oil-absorbing cotton pads, and it is impossible to accurately move the clamps and fix the new oil-absorbing cotton pads. A filter turnover plate for printed circuit board etching is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a filter turnover plate for etching a printed circuit board, comprising an etching liquid collection tank and a filter plate, the filter plate being movably connected to the top surface of the etching liquid collection tank, a filter tank being provided inside the filter plate, a plurality of filter baffles being fixedly connected inside the filter tank, an oil suction assembly being movably connected inside the filter tank, the oil suction assembly comprising a mounting bracket, an oil suction frame and a positioning bracket, the oil suction frame comprising a fixed frame and an oil-absorbing cotton sheet, the oil suction frame being movably connected to the inside of the mounting bracket, the two positioning brackets being movably connected to the inside of the mounting bracket, and the two positioning brackets being respectively arranged at the two ends of the top surface of the oil suction frame.

[0007] Preferably, positioning rods are symmetrically fixedly installed on both ends of the mounting frame, and horizontal plates are fixedly installed on both sides of the mounting frame.

[0008] Preferably, a rectangular groove No. 1 is symmetrically provided at both ends of the mounting frame.

[0009] Preferably, a second rectangular groove is provided in the middle of the two positioning frames, and positioning holes are provided at both ends of the two positioning frames, and the positioning rods are movable through the interior of the positioning holes.

[0010] Preferably, limiting rods are fixedly installed on the four corners of the top surface of the etching liquid collecting tank.

[0011] Preferably, the four corners of the filter disc are respectively provided with limiting holes, and the limiting rods are movable through the limiting holes.

[0012] Preferably, handles are fixedly mounted on both sides of the filter disc.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, the oil absorption cotton sheet is clamped in the inside of the mounting frame and the new oil absorption assembly is clamped in the inside of the filter tank to complete the replacement of the oil absorption assembly. There is no need for workers to use rubber gloved hands to replace the oil absorption cotton sheet and adjust the position of the oil absorption cotton sheet, thereby improving the efficiency of replacing the oil absorption cotton sheet.

[0015] 2. In the present invention, when the oil absorption frame is stably stuck inside the mounting frame and placed inside the filter tank, the etching liquid containing oil and suspended impurities can pass through the No. 1 rectangular groove, the oil-absorbing cotton sheet and the No. 2 rectangular groove in sequence, so that the oil-absorbing cotton sheet can fully absorb the oil and suspended impurities in the filtered etching liquid, and the mounting frame and the positioning frame will not block the oil-absorbing cotton sheet, thereby ensuring that the oil-absorbing cotton sheet can fully absorb the filtered impurities.
