[0024] The circuit board etching spraying device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in order to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments, and other alternative methods may be used by those skilled in the art; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0025] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0026] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a circuit board etching spraying device, including: a workbench 1, a column 2 fixedly mounted on the top of the workbench 1, a motor 3 fixedly mounted on the outer wall of the column 2, a first lead screw 4 fixedly mounted on the output shaft of the motor 3, a movable seat 5 threadedly connected to the outer wall of the first lead screw 4, a solution tank 6 fixedly mounted on the top of the movable seat 5, a liquid pump 19 fixedly mounted on the bottom of the inner wall of the solution tank 6, a connecting pipe 20 fixedly mounted on the output port of the liquid pump 19, a rubber tube 8 at the top of the connecting pipe 20, a slide 11 fixedly mounted on the end of the rubber tube 8, a connector 12 fixedly mounted on the bottom of the slide 11, a spray head 13 communicating with the inside of the connector 12, a limiting groove 10 opened in the middle of the movable seat 5, a limiting seat 14 slidably connected to the inner wall of the limiting groove 10, a fixing plate 26 fixedly mounted on the outer wall of the solution tank 6, a sliding groove 9 opened in the middle of the fixing plate 26, an injection pipe 7 penetrating through the top of the solution tank 6, and a motor 25 fixedly mounted on the outer wall of the solution tank 6. The output shaft of the 25 is fixedly equipped with a second lead screw 18. A first liquid guide plate 22 and a second liquid guide plate 23 are fixedly installed on the outer wall of the worktable 1. A collection shell 15 is located below the first liquid guide plate 22. A slot 24 is opened on the outer wall of the collection shell 15. A filter screen 17 is inserted into the inner wall of the slot 24. Rubber strips 21 are provided on both outer walls of the filter screen 17. A liquid outlet pipe 16 is provided at the bottom of the collection shell 15. The worktable 1, column 2, motor 3, first lead screw 4, moving seat 5, and solution are connected. The structure of the box 6, injection pipe 7, rubber tube 8, slide 9, limiting groove 10, slide 11, connector 12, spray head 13, and limiting seat 14 allows the user to adjust the position of the slide 11 and the spray head 13 by operating the motor 3 and motor 25 respectively during the use of the device. This enables automated adjustment of the spray head 13 position to spray the circuit board with etching solution, thereby improving the automation of the device, the user's spraying efficiency on the circuit board, and the spraying range of the device.

[0027] like Figure 1 and Figure 2 As shown, the inner wall of the slide groove 9 is slidably connected to the outer wall of the slide block 11, and the inner wall of the limiting groove 10 is slidably connected to the outer wall of the limiting seat 14. Through the structure of the limiting groove 10 and the limiting seat 14, during the operation of the motor 25, the rotation of the second lead screw 18 can drive the slide block 11 and the spray head 13 to move together, so that the spray head 13 can spray different positions of the circuit board, thereby improving the spraying range of the device on the circuit board.

[0028] like Figure 1 and Figure 2As shown, there are two rubber tubes 8, and both rubber tubes 8 are symmetrically distributed along the outer wall of the workbench 1. Through the structure of the two rubber tubes 8, due to the elasticity and easy storage characteristics of the rubber tube material, it is possible to ensure that the rubber tubes 8 can extend and retract with the moving distance of the slide 11 during the movement, thereby ensuring that the movement of the slide 11 will not be disturbed, and thus ensuring the normal operation of the device.

[0029] like Figure 2 and Figure 3 As shown, the inner wall of the solution tank 6 is filled with etching solution, and the outer wall of the slide 11 has a circular hole. The inner wall of the circular hole is threaded to the outer wall of the second lead screw 18. Through the structure of the solution tank 6, the etching solution in the two solution tanks 6 is used to supply etching solution for the spraying operation, thereby ensuring that the device can operate for a long time and avoiding insufficient etching solution. This ensures the duration of the device's spraying operation on the circuit board. The slide 11 can drive the spray head 13 to move, so as to achieve the effect of spraying different positions on the circuit board.

[0030] like Figure 2 and Figure 4 As shown, the shape of the slot 24 is adapted to the shape of the filter screen 17, and the outer wall of the rubber strip 21 is tightly fitted to the inner wall of the slot 24. Through the structure of the rubber strip 21, after the spraying operation, the excess etching liquid will enter the collection shell 15 and come into contact with the filter screen 17, thereby achieving the effect of collecting and filtering the etching liquid, avoiding the presence of too many impurities in the etching liquid that would affect the subsequent etching quality, and thus achieving the effect of recycling the excess etching liquid, reducing the consumption of etching liquid by the device.

[0031] like Figure 1 and Figure 3 As shown, connector 12 is connected to the interior of solution tank 6 via rubber tube 8. Workbench 1 is connected to the interior of collection shell 15 via first guide plate 22 and second guide plate 23. Through the structure of first guide plate 22 and second guide plate 23, after the spraying operation is completed, the first guide plate 22 and second guide plate 23 can guide the etching liquid flowing on workbench 1, so that the etching liquid can flow into collection shell 15, thereby achieving the effect of filtering the used etching liquid, thus ensuring the recycling effect of the device on etching liquid, reducing the operating cost of the device, and improving the precision matching of the internal components of the device.

[0032] The technical solution provided by this utility model involves placing the circuit board on the workbench 1 during operation. Then, the moving seat 5 is moved laterally by the operation of the motor 3 and the motor 25. The operation of the motor 25 causes the slide 11, the limiting seat 14, and the spray head 13 to move longitudinally, thereby achieving the effect of spraying different positions on the circuit board. This improves the automation and spraying range of the device, thus enhancing its practicality. After the spraying operation is completed, the excess etching solution will enter the collection shell 15 through the guidance of the first guide plate 22 and the second guide plate 23. At this time, the impurities in the etching solution will be separated from the etching solution, making it easier for the user to recycle the filtered etching solution. This improves the utilization rate of the etching solution and reduces the operating cost of the device.

[0033] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0034] Those skilled in the art will understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing related hardware. The program can be stored in a computer-readable storage medium, such as ROM / RAM, magnetic disk, optical disk, etc.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
