Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to an etching spray frame for circuit board manufacturing. Background Technology

[0002] Circuit board manufacturing refers to the process of laying out electronic circuits on an insulating substrate through a series of complex technological steps and performing related processing to create a printed circuit board (PCB) that can achieve specific electrical connections and functional requirements.

[0003] An existing patent (publication number: CN222283607U) discloses an etching spray frame for circuit board production, including a frame body. Several transverse flow channels are formed in the middle of the bottom of the inner wall of the frame body. Several uniformly distributed first nozzles are fixedly connected to the surfaces of each transverse flow channel. This utility model, an etching spray frame for circuit board production, has several transverse flow channels and one vertical flow channel. Several first nozzles and several second nozzles are respectively arranged on the transverse and vertical flow channels. The arrangement of several second nozzles in the vertical direction can compensate for etching, significantly improving the uniformity of etching. Two limiting strips, under the action of several telescopic rods and several telescopic springs, initially limit the circuit board. Rotating four knobs clockwise drives four threaded rods to rotate, thereby moving four limiting blocks and further limiting and fixing the circuit board, ensuring stable operation of the circuit board.

[0004] During use, the above-mentioned spray frame rotates four knobs clockwise, which in turn drives four threaded rods to rotate, thereby pushing four limit blocks to move and further limit and fix the circuit board, ensuring stable operation of the circuit board. Since the circuit board is fixed, only one side will be sprayed during spraying. Because the bottom surface of the circuit board is in contact with the spray frame, the other side of the circuit board may not be sprayed evenly, thus affecting the spraying quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an etching spray frame for circuit board production, which has the advantages of stable and flexible clamping and improved spraying quality, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an etching spray frame for circuit board production, comprising a frame body, wherein a plurality of rotating rods are rotatably connected to the inner wall of the frame body, and a clamping swing assembly is installed on the outer surface of each of the plurality of rotating rods;

[0007] Each of the clamping swing assemblies includes a support frame, each support frame is fixedly connected to a nearby rotating rod, each rotating rod has a limit frame rotatably connected to its outer surface, each rotating rod has a connecting plate fixedly connected to its front end, and two sliding rods are slidably connected to the inner wall of the frame, with the upper end of each connecting plate hinged to a nearby sliding rod.

[0008] The above solution, by setting up a clamping swing component, can firmly clamp the circuit board during the circuit board processing, ensuring that the circuit board maintains a stable position in each process and will not be displaced due to external interference.

[0009] Furthermore, a circuit board body is provided between each of the support frames and each adjacent limiting frame, and a set of rubber protrusions is fixedly connected to one side of each limiting frame and the circuit board adjacent to it, and each rubber protrusion is in contact with the circuit board body adjacent to it.

[0010] The above solution enables flexible clamping of the circuit board body by setting rubber bumps, thus avoiding damage to the circuit board body during clamping.

[0011] Furthermore, each of the limiting frames has two elastic buckles fixedly connected to its outer surface, and each elastic buckle engages with the adjacent support frame.

[0012] The above solution uses elastic buckles to fix the limit frame, allowing it to be connected to the support frame. This enables the support frame, circuit board body, and limit frame to swing synchronously when the support frame swings.

[0013] Furthermore, two limiting cylinders are fixedly connected to the inner wall of the frame, and the left ends of the two slide rods are slidably inserted into the limiting cylinders close to them.

[0014] The above solution allows the limiting cylinder to limit the sliding rod, enabling it to slide stably within the frame.

[0015] Furthermore, two telescopic rods are installed on the inner wall of the frame, and the output ends of the two telescopic rods are fixedly connected to the adjacent sliding rods.

[0016] Through the above scheme, the telescopic rod can push the slide rod to slide within the frame, so that the slide rod can drive the rotating rod to rotate through the connecting plate, thereby enabling the support frame to drive the circuit board body to swing.

[0017] Furthermore, each of the limiting frames is fixedly connected to an arc-shaped plate at its upper end, and two sliding plates are slidably connected to the upper surface of the frame.

[0018] By using the above scheme, the sliding plate and the arc plate are designed to work together so that when the sliding plate slides to the left, the limiting frame and the bearing frame are fixed together by elastic buckles, and when the sliding plate slides to the right, the bearing frame and the limiting frame are separated.

[0019] Furthermore, the outer surface of the frame is provided with multiple connecting slots.

[0020] The above solution allows multiple connecting slots to facilitate the application of etching solution to the circuit board body by externally angled spray nozzles, ensuring the normal operation of the spraying process.

[0021] Furthermore, a filter plate is slidably inserted into the bottom end of the frame.

[0022] The above solution allows for the filtration of residues on the circuit board, facilitating the recycling of the used spray etching solution.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] This etching spray rack for circuit board production features a clamping and swinging assembly that securely holds the circuit board during processing, ensuring a stable position throughout the process and preventing displacement due to external interference. Furthermore, the rubber bumps flexibly contact the circuit board surface, effectively preventing scratches and abrasions while maintaining stable clamping. Additionally, during the spraying process, the clamping and swinging assembly allows the circuit board to swing within the rack, ensuring even coverage of the etching solution and significantly improving the spraying effect. This results in more uniform and thorough etching and cleaning of the circuit board. Attached Figure Description

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, an etching spray rack for circuit board production includes a frame 1, with multiple rotating rods 2 rotatably connected to the inner wall of the frame 1, and clamping swing components 3 installed on the outer surface of each of the multiple rotating rods 2.

[0035] Please see Figure 1 , Figure 2 and Figure 3 Each clamping swing assembly 3 includes a support frame 301, each support frame 301 is fixedly connected to a nearby rotating rod 2, and a limit frame 302 is rotatably connected to the outer surface of each rotating rod 2. A connecting plate 303 is fixedly connected to the front end of each rotating rod 2. Two sliding rods 304 are slidably connected to the inner wall of the frame 1. The upper end of each connecting plate 303 is hinged to the nearby sliding rod 304. By setting the clamping swing assembly 3, the circuit board can be firmly clamped during the circuit board processing, ensuring that the circuit board maintains a stable position in each process and will not be displaced due to external interference. Secondly, the rubber bump 5 is in flexible contact with the surface of the circuit board, which can effectively avoid scratches, wear and other damage to the surface of the circuit board while achieving stable clamping. Furthermore, when the circuit board body 4 is sprayed, the clamping swing assembly 3 can flexibly drive the circuit board body 4 to swing within the frame 1, so that the sprayed etching liquid can evenly cover all parts of the circuit board body 4, which greatly improves the spraying effect and makes the etching, cleaning and other treatments of the circuit board more uniform and thorough.

[0036] Please see Figure 1 , Figure 2 and Figure 3Each support frame 301 is provided with a circuit board body 4 between each adjacent limiting frame 302. Each limiting frame 302 and the side of each limiting frame 302 adjacent to the circuit board are fixedly connected with a set of rubber protrusions 5. Each rubber protrusion 5 contacts the adjacent circuit board body 4. The rubber protrusions 5 can achieve flexible clamping of the circuit board body 4 and avoid damage to the circuit board body 4 when clamping it. Each limiting frame 302 has two elastic buckles 6 fixedly connected to its outer surface. Each elastic buckle 6 is engaged with the adjacent support frame 301. The elastic buckles 6 can fix the limiting frame 302 so that the limiting frame 302 can be connected to the support frame 301. When the support frame 301 swings, the support frame 301, the circuit board body 4, and the limiting frame 302 swing synchronously.

[0037] Please see Figure 1 , Figure 2 and Figure 4 Two limiting cylinders 7 are fixedly connected to the inner wall of the frame 1. The left ends of the two sliding rods 304 are slidably inserted into the limiting cylinders 7 that are close to them. The limiting cylinders 7 can limit the sliding rods 304, so that the sliding rods 304 can slide stably within the frame 1. Two telescopic rods 8 are installed on the inner wall of the frame 1. The output ends of the two telescopic rods 8 are fixedly connected to the sliding rods 304 that are close to them. The telescopic rods 8 can push the sliding rods 304 to slide within the frame 1, so that the sliding rods 304 can drive the rotating rod 2 to rotate through the connecting plate 303, thereby enabling the support frame 301 to drive the circuit board body 4 to swing.

[0038] Please see Figure 1 , Figure 2 and Figure 3 Each limiting frame 302 has an arc-shaped plate 9 fixedly connected to its upper end. Two sliding plates 10 are slidably connected to the upper surface of the frame 1. The sliding plates 10 and the arc-shaped plates 9 are designed to allow the limiting frame 302 and the support frame 301 to be fixed together by the elastic buckle 6 when the sliding plates 10 slide to the left. When the sliding plates 10 slide to the right, the support frame 301 and the limiting frame 302 are separated. The outer surface of the frame 1 has multiple connecting grooves 11. The multiple connecting grooves 11 facilitate the spraying of etching solution onto the circuit board body 4 by the external oblique spray head, ensuring the normal operation of the spraying work. A filter plate 12 is slidably inserted into the bottom of the frame 1. The filter plate 12 can filter the residue on the circuit board body 4, making it easy to recycle the used sprayed etching solution.

[0039] In this embodiment, an etching spray rack for circuit board production is provided. By setting a clamping swing component 3, the circuit board can be firmly clamped during the circuit board processing, ensuring that the circuit board maintains a stable position in each process and will not be displaced due to external interference. Secondly, the rubber bumps 5 flexibly contact the surface of the circuit board, which can effectively avoid scratches, wear and other damage to the surface of the circuit board while achieving stable clamping. Furthermore, when the circuit board body 4 is sprayed, the clamping swing component 3 can flexibly drive the circuit board body 4 to swing within the rack 1, so that the sprayed etching liquid can evenly cover all parts of the circuit board body 4, which greatly improves the spraying effect and makes the etching, cleaning and other treatments of the circuit board more uniform and thorough.

[0040] It should be noted that each elastic buckle 6 is made of elastic steel.

[0041] The working principle of the above embodiment is as follows: First, the circuit board body 4 is placed between each support frame 301 and its adjacent limiting frame 302. Then, the sliding plate 10 is slid to the left so that after the sliding plate 10 contacts the arc plate 9, the elastic buckle 6 can engage with the support frame 301, thereby allowing the rubber protrusion 5 to contact the circuit board body 4, achieving stable and flexible clamping of the circuit board body 4. This ensures that the circuit board body 4 maintains a stable position in each process and will not be displaced due to external interference. During the spraying process, the telescopic rod 8 can push the sliding rod 304 on the frame. The slide bar 304 slides within the body 1. When sliding, it can drive the rotating rod 2 to swing through the connecting plate 303. This causes the rotating rod 2 to drive the support frame 301, the circuit board body 4, and the limiting frame 302 to swing synchronously. By swinging the circuit board body 4 while keeping it stable, the uniformity of the etching solution sprayed onto the circuit board body 4 can be improved, thereby improving the quality of the spraying. This allows the sprayed etching solution to evenly cover all parts of the circuit board body 4, greatly improving the spraying effect and making the etching, cleaning, and other treatments of the circuit board body 4 more uniform and thorough.
