Description

Technical Field

[0001] This utility model applies to the field of circuit board manufacturing technology, and in particular relates to a classifiable etching device for printed circuit boards. Background Technology

[0002] Currently, etching is a process that removes unwanted parts of a material surface using chemical or physical methods to form a desired pattern or shape. In circuit board manufacturing, the purpose of etching is to remove copper foil from non-circuit parts to obtain the desired circuit pattern.

[0003] However, currently, when etching circuit boards, positioning holes are drilled at the four corners of the board beforehand to suspend it through these holes inside a container filled with etching solution. The etching solution is then used to etch the surface of the board. However, when suspending and fixing the boards, it is impossible to adjust the suspension of boards of different widths collectively. This forces the operator to perform multiple suspension steps sequentially, which is time-consuming, labor-intensive, and reduces the efficiency of the etching process. Therefore, we propose a categorizable etching device for printed circuit boards. Utility Model Content

[0004] The main objective of this invention is to provide a classifiable etching device for printed circuit boards, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sortable etching apparatus for printed circuit boards, wherein a transmission frame is horizontally fixedly installed on the top surface of the holding pool, and the number of transmission frames is several sets, and a sliding plate is slidably installed on the outside of each transmission frame, and the number of sliding plates is several sets.

[0007] Each of the transmission frames is equipped with an adjustment mechanism, and the adjustment mechanism is connected to the sliding plate. A synchronization mechanism is connected between the outer sides of every two sets of adjustment mechanisms, and the rotation of the synchronization mechanism is located inside the transmission frame.

[0008] A circulation mechanism is provided on the side of the holding tank.

[0009] By adopting the above technical solution, the distance between the sliding plate and the hanging hook located outside the transmission frame is adjusted through the connection and transmission action of the adjustment mechanism and the synchronization mechanism. This allows the operator to adjust the suitability of hanging circuit boards of the same size, ensuring that multiple sets of circuit boards can be stably suspended in the holding tank. This reduces the number of operation steps required for the operator to suspend multiple sets of circuit boards and improves the etching efficiency of the circuit boards.

[0010] As an optional solution to the technical solution of this application, the adjustment mechanism includes a bidirectional lead screw, and a fixing plate is fixedly installed on the inner side of each transmission frame. The number of fixing plates is several sets. A bidirectional lead screw is rotatably installed between the sides of every two sets of fixing plates through a bearing. A transmission sleeve is threadedly connected to both ends of the outer surface of each bidirectional lead screw. A transmission block is fixedly installed on the outer surface of each transmission sleeve. The side of the transmission block is fixedly connected to the outer side of the sliding plate. A limiting groove is opened inside the side of each transmission frame, and the transmission block is slidably inserted into the limiting groove. A hanging hook is fixedly installed on the side surface of each sliding plate.

[0011] By adopting the above technical solution, the transmission sleeves located inside the transmission frame and sleeved on both sides of the bidirectional lead screw can be driven by the rotational transmission action of the bidirectional lead screw, so that the transmission sleeves can move towards each other or relative to each other inside the transmission frame, thereby adjusting the spacing of the sliding plate and the suspension hook located outside the transmission frame.

[0012] As an optional solution to the technical solution of this application, the transmission mechanism includes a transmission rod, with a transmission rod fixedly installed between the sides of every two sets of bidirectional lead screws, and the transmission rod is rotatably installed inside the transmission frame. A servo motor is fixedly installed on the outer surface of each transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the outer side of the bidirectional lead screw through a coupling.

[0013] By adopting the above technical solution, multiple sets of bidirectional lead screws can be driven to rotate synchronously and in the same direction through the transmission action of the transmission rod.

[0014] As an optional solution to the technical solution of this application, the circulation mechanism includes a fixed pipe and a conveying pipe. The conveying pipes are horizontally fixedly installed on both sides inside the holding tank. Each conveying pipe has a connecting bend fixedly connected to its side. The fixed pipe is fixedly installed on the outside of the holding tank, and the side of the connecting bend is fixedly connected to the side of the fixed pipe. Each conveying pipe has a liquid inlet on its side, and there are several sets of liquid inlets. A liquid pump is fixedly connected to the outside of the fixed pipe, and the inlet and outlet of the liquid pump are fixedly connected to the side of the fixed pipe.

[0015] By adopting the above technical solution, through the connection between the conveying pipe and the fixed pipe, and under the operation of the liquid pump, the etching liquid inside the holding tank can be drawn from the right side and discharged from the left side, so that the etching liquid can circulate inside the holding tank, ensuring that the etching liquid can fully etch and process the surface of the circuit board during the flow.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present application discloses a categorizable etching apparatus for printed circuit boards. This apparatus comprises multiple sets of transmission frames at the top of a holding tank, and multiple sets of bidirectional lead screws connected to the transmission frames via transmission rods. When a servo motor operates, and under the transmission action of the transmission rods, the multiple sets of bidirectional lead screws can be driven to rotate synchronously within the transmission frames. Combined with the rotational transmission action of the bidirectional lead screws on the transmission sleeves, this drives the transmission sleeves located inside the transmission frames and fitted on both sides of the bidirectional lead screws. This allows the transmission sleeves to move towards or away from each other within the transmission frames, thereby adjusting the spacing between the sliding plate and the hanging hook located outside the transmission frames. This allows the operator to adjust the hanging applicability of circuit boards of the same size, ensuring that multiple sets of circuit boards can be stably suspended in the holding tank. This reduces the number of steps required for suspending multiple sets of circuit boards and improves the etching efficiency of the circuit boards.

[0018] 2. The present application provides a classifiable etching apparatus for printed circuit boards, which, by providing conveying pipes on both sides of the container, and connecting the conveying pipes with a connecting bend and a fixed pipe on the outside, allows the etching liquid inside the container to be drawn from the right side and discharged from the left side under the operation of the pump. This allows the etching liquid to circulate inside the container, ensuring that the etching liquid can fully etch the surface of the circuit board during the flow process.

Detailed Implementation

[0023] like Figure 1-3As shown, this utility model provides a technical solution: a classifiable etching device for printed circuit boards. A transmission frame 2 is horizontally fixedly installed on the top surface of the holding tank 1, and there are several sets of transmission frames 2. A sliding plate 21 is slidably installed on the outside of each transmission frame 2, and there are several sets of sliding plates 21. An adjustment mechanism is provided inside each transmission frame 2, and the adjustment mechanism is connected to the sliding plate 21 in a transmission connection. The adjustment mechanism includes a bidirectional lead screw 24. A fixing plate 23 is fixedly installed on the inside of each transmission frame 2, and there are several sets of fixing plates 23. A bidirectional lead screw 24 is rotatably installed between the sides of every two sets of fixing plates 23 through a bearing. A transmission sleeve 26 is movably sleeved on both ends of the outside of each bidirectional lead screw 24 through a thread. A transmission block 27 is fixedly installed on the outside surface of each transmission sleeve 26, and the side of the transmission block 27 is fixedly connected to the outside of the sliding plate 21.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a synchronization mechanism is connected between the outer sides of each pair of adjustment mechanisms, and the synchronization mechanism rotates inside the transmission frame 2. The transmission mechanism includes a transmission rod 25. A transmission rod 25 is fixedly installed between the sides of each pair of bidirectional lead screws 24, and the transmission rod 25 is rotatably installed inside the transmission frame 2. A servo motor 28 is fixedly installed on the outer surface of each transmission frame 2, and the transmission shaft side of the servo motor 28 is fixedly connected to the outer side of the bidirectional lead screw 24 through a coupling.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each transmission frame 2 has a limiting groove 29 inside its side, and the transmission block 27 is slidably inserted into the limiting groove 29. Each sliding plate 21 has a hanging hook 22 fixedly installed on its side surface.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a circulation mechanism is provided on the side of the holding tank 1. The circulation mechanism includes a fixed pipe 3 and a conveying pipe 32. Conveying pipes 32 are horizontally fixedly installed on both sides inside the holding tank 1. A connecting bend 31 is fixedly connected to the side of each conveying pipe 32. A fixed pipe 3 is fixedly installed on the outside of the holding tank 1, and the side of the connecting bend 31 is fixedly connected to the side of the fixed pipe 3. A liquid inlet 33 is opened on the side of each conveying pipe 32, and there are several sets of liquid inlet 33. A liquid pump 34 is fixedly connected to the outside of the fixed pipe 3, and the inlet and outlet of the liquid pump 34 are fixedly connected to the side of the fixed pipe 3.

[0027] During operation, based on the required etch width of the circuit board, the servo motor 28 is activated via an external control switch, causing it to rotate synchronously within the transmission frame 2, driven by the bidirectional lead screw 24. Combined with the transmission rod 25's connection to multiple bidirectional lead screws 24, these lead screws 24 within the transmission frame 2 rotate synchronously and in the same direction. This, combined with the rotation of the bidirectional lead screws 24 to the transmission sleeves 26, and the connection of the limiting slide groove 29 to the transmission block 27, allows the multiple transmission sleeves 26 to move horizontally and synchronously within the transmission frame 2. Subsequently, under the transmission action of the transmission block 27, this provides power to the sliding plate 21 and the suspension... Hook 22 moves horizontally on the outside of transmission frame 2, adjusting the distance between adjacent sliding plates 21 and hanging hook 22, so that the positioning hole on the side of the circuit board can be inserted into the outer wall of the hanging hook 22 to suspend and fix the circuit board. Repeat the above operation to suspend multiple circuit boards of different sizes and models on the front side of transmission frame 2 at different positions. Suspend multiple circuit boards on the top inside the holding tank 1, then start the liquid pump 34 to make it run and generate negative pressure suction inside the fixed tube 3, so that the etching liquid inside the holding tank 1 can be circulated and transported inside the holding tank 1, so that the etching liquid can fully etch the surface of the circuit board during the circulation process.
