Technical Field

[0001] The utility model relates to the technical field of PCB etching, in particular to a device capable of automatically adjusting etching parameters. Background Art

[0002] In PCB production, etching is an important step after the PCB is electroplated. The main purpose of etching is to remove the unwanted copper after electroplating, leaving the designed conductive path. Specifically, a resist is applied on the conductive path, and then the resist is heated and cured with ultraviolet light. The PCB is then placed in a strong acid chemical solution to dissolve the exposed copper foil, leaving the designed conductive path. Finally, a solder resist remover is used to remove the resist, exposing the conductive path, completing the etching process.

[0003] In the prior art, the entire operation process of PCB board etching is purely automated. However, in traditional etching line production, it is necessary to manually determine the etching data first, place the first PCB board for testing and adjustment, and then adjust the etching line speed after confirming the line width and line spacing of the first piece based on manual measurement by personnel. After the data of the first PCB is correct, when mass production is carried out, the production process may cause unstable chemicals, resulting in etching problems. During production, a dedicated person is required to follow up to confirm the quality status and manually adjust the line speed. If the personnel do not confirm and adjust in time, the PCB board will be scrapped due to problems such as incomplete etching, thin lines, and film jamming. Manual adjustment will seriously affect the production quality, cost and efficiency of the PCB board. Therefore, there is an urgent need for a device that can automatically adjust the production parameters of the etching line to solve the above-mentioned technical problems. Utility Model Content

The transmission assembly is also provided with a fixing part, and the first screw rod is sleeved on the fixing part. When the drive motor is working, it drives the optical camera assembly to perform linear motion through the connecting plate.

[0015] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0016] In the following description, examples are provided to provide a deeper understanding of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. It should be understood that the specific embodiments described are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0018] See also Figure 1 The utility model is a device that can automatically adjust etching parameters. It is connected to the etching device and includes a base 1. The base 1 is provided with a control box 2, an optical detection mechanism 3 and a transmission component 4. The transmission component 4 is fixedly arranged on the base 1, and the optical detection mechanism 3 is fixedly arranged above the transmission component 4. The control box 2 is electrically connected to the optical detection mechanism 3. When working, the PCB board is moved to the bottom of the optical detection mechanism 3 through the transmission component 4, and the optical detection mechanism 3 detects the PCB board and transmits the detection data to the control box 2. This device is mainly arranged behind the etching device. After the etching of the PCB board is completed, it reaches the bottom of the optical detection mechanism 3 through the transmission component 4. The optical detection mechanism 3 performs circuit detection on the circuit on the PCB board, and then receives the detection data through the control box 3 and adjusts the process parameters of the etching device according to the PCB board that does not meet the design size.

[0019] The working principle of this utility model is:

[0020] The PCB board arrives at the bottom of the optical detection mechanism 3 through the transmission component 4, and the positioning sensor is used to determine whether the PCB board has reached the detection position. Then, the optical detection mechanism 3 is used to detect the line length, line spacing, line width of the PCB board and whether there is any residual copper on the surface of the PCB board. The driving motor 32 drives the optical camera component 31 to perform linear motion scanning detection on the PCB board. Then, the optical detection mechanism 3 sends the detection information of the PCB board to the control box 2, and the control box 2 judges whether the line length, line spacing and line width of the PCB board are in accordance with the design dimensions. If they meet the design dimensions, the etching production is continued according to the current parameters of the etching line. If not, the parameters of the machines on the etching line are adjusted accordingly according to whether the line length, line spacing and line width of the PCB board are less than or greater than the design dimensions. Specifically, the line speed of the etching line, the concentration of the sprayed etching solution and the spraying pressure are adjusted. By adjusting the above parameters, the etching degree of the subsequent PCB is adjusted so that the subsequently etched PCB board can meet the design dimensions.

[0021] In this embodiment, the optical detection mechanism 3 mainly includes an optical camera component 31, a drive motor 32 and a connecting plate 33. The optical camera component 31 and the drive motor 32 are arranged on the connecting plate 33. The drive motor 32 is penetrated by a first screw rod 34. The transmission component 4 is also provided with a fixing member 35, and the first screw rod 34 is sleeved on the fixing member 35. When the drive motor 32 is working, the optical camera component 31 is driven to move linearly through the connecting plate 33. The optical detection component will perform optical detection on the PCB board on the transmission component 4 to detect whether the copper cladding outside the designed circuit on the PCB board is completely removed. At the same time, the length, line spacing, line width and other lengths of the designed circuit are measured to determine whether it meets the designed dimensions. At the same time, the fixing member 35 can be configured as a positioning sensor. When the positioning sensor detects that the PCB board has moved to the detection position, a start signal is sent to the drive motor 32 and the optical detection mechanism 3 is started to perform optical detection on the PCB board.

[0022] In this embodiment, the conveying assembly 4 includes a conveying port 42, a transmission roller 41, a conveyor belt and a transmission motor. The output shaft of the transmission motor is fixedly connected to the transmission roller 41. The conveying port 42 is arranged at one end of the base 1, and the conveyor belt is sleeved on the transmission roller 41. The conveyor belt and the transmission motor are not reflected in this application.

[0023] In this embodiment, a lifting mechanism 5 is further included, which includes a lifting base 53, a lifting motor 51 and a marking plate 52. The lifting base 53 is fixedly mounted on the conveying assembly 4, and the lifting motor 51 is fixedly arranged on the lifting base 53. The output shaft of the lifting motor 51 is fixedly connected to the marking plate 52. When the optical inspection mechanism 3 detects that the PCB board does not meet the design size, that is, the PCB board is scrapped, the marking plate is controlled to rise and fall by the lifting motor to mark the PCB as scrapped.

[0024] The advantages of this utility model are:

[0025] 1. The control box receives the inspection data of the PCB board from the optical inspection mechanism, feeds it back to the etching device and adjusts the parameters.

[0026] 2. It reduces the error of manual detection and adjustment of etching device parameters, and improves the production efficiency of the etching process in PCB board production.
