Description

Technical Field

[0001] The utility model relates to the field of etching machines, in particular to an etching cavity with adjustable temperature. Background Technique

[0002] A chemical etching machine is a technology that removes materials through chemical reactions or physical impacts. The automatic chemical etching machines seen in the market today use high-pressure spraying and the linear movement of the etched plate to form a continuous feeding state to corrode workpieces to improve production efficiency. During the use of the etching machine, the etching liquid can be recycled;

[0003] In the prior art, a structure of an etching cavity of an etching machine proposed in the utility model patent with the publication number of CN 214075238 U can effectively reduce the frictional resistance, increase the stability of the driven shaft. The addition of the rotating rod and the slider enables the movable plate to reciprocate. The addition of the first chute restricts the movement trajectory of the sliding rod. The addition of the spring enables the sliding plate to return to its original position. The filter plate inside the etching cavity of this etching machine can be cleaned after being used for a period of time, reducing the impact on the filtration efficiency; however, its filter screen will be impacted by the liquid containing impurities during actual use, and the filter screen is prone to deformation, clogging, and poor stability. At the same time, the impurities swept during the cleaning of the filter screen cannot be effectively treated and still remain inside the device, affecting the use safety of the equipment; it also does not have the ability to adjust the temperature inside the cavity and cannot adapt to different working requirements and working conditions. Therefore, we need to upgrade and transform on the basis of the existing technology to overcome the existing problems and deficiencies. Content of the Utility Model

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 -4 shows, this embodiment provides a design of an etching chamber with adjustable temperature, including a device body 1. The device body 1 contains an inner cavity 2. Inside the inner cavity 2, there is a workbench 3, and a water guide pipe 4 is arranged on one side of the workbench 3. At the upper end inside the inner cavity 2, there is a sprayer 5. Below the workbench 3 and inside the inner cavity 2, there is a filter tank 6. Inside the filter tank 6, there is a partition plate 7, and a filter net 8 is arranged on the right side of the partition plate 7. The water guide pipe 4 is inserted to the lower end of the filter net 8. On the left side outside the filter tank 6, there is a circulation pump 11 connected. At the upper end of the circulation pump 11, there is a circulation pipe 12, and the upper end of the circulation pipe 12 is conductively connected to the inside of the sprayer 5. The outside of the inner cavity 2 is electrically connected to a controller 15. Inside the inner cavity 2, there is a heating pipe 16, and inside the heating pipe 16, there is a heat conduction plate 17. Inside the heat conduction plate 17, there is a temperature sensor 18. Between the heating pipe 16 and the outer wall of the inner cavity 2, there is a heat preservation plate 19.

[0024] Preferably, the front end of the inner cavity 2 is hinged with an outer cavity door 21, and a transparent observation window 22 is arranged at the upper end of the outer cavity door 21. Through the observation window 22, it is convenient to observe the internal working conditions of the inner cavity 2 in real time. In the center of the workbench 3, there is a placement table 31, and the placement table 31 is convexly installed on the workbench 3. Through the placement table 31, it is convenient to place the workpiece to be processed.

[0025] Preferably, an installation frame 9 is fixedly welded to the right side of the partition plate 7. The filter screen 8 is placed on the installation frame 9 and the position of the filter screen 8 is lower than that of the partition plate 7. The installation frame 9 facilitates the convenient removal, placement and installation of the filter screen 8. A sewage discharge port 10 is provided at the lower right end of the filter tank 6, which facilitates the cleaning of the precipitated impurities through the sewage discharge port 10. A support base 13 is provided at the lower end of the circulation pump 11, and the support base 13 is fixedly installed on the outer wall of the filter tank 6, which facilitates the installation of the circulation pump 11. An inner baffle 14 is installed on the upper left side of the workbench 3, and the inner baffle 14 shields the right side of the circulation pipe 12, which facilitates the protection of the circulation pipe 12 through the inner baffle 14.

[0026] The working principle and process of the present utility model: When in use, first connect the external power supply, and control the heating tube 16 to work through the controller 15. The heating tube 16 raises the temperature inside the inner cavity 2 through the heat conduction plate 17, and the temperature is monitored in real time through the temperature sensor 18. Stop when the specified temperature is reached, so that the temperature inside the inner cavity 2 is always kept constant. At this time, place the workpiece on the placement table 31 to etch it. The etching solution is sprayed onto the lower workpiece through the sprayer 5. After the solution is sprayed, it flows downward through the water guide pipe 4 and directly enters the inside of the filter tank 6. When the height of the solution reaches the position of the filter screen 8, it contacts the bottom surface of the filter screen 8 and is filtered. The solution higher than the filter screen 8 flows to the left cavity of the filter tank 6 through the upper end of the partition plate 7 on one side. At this time, when a certain amount of filtered solution is reached on the left side, the circulation pump 11 can be started. The circulation pump 11 pumps the solution from the left side of the filter tank 6 and pumps it into the sprayer 5 through the circulation pipe 12 for recycling. The filter screen 8 can be directly removed from the installation frame 9 and replaced. After using for a period of time, the impurities precipitated on the right side of the filter tank 6 can be cleaned and discharged through the sewage discharge port 10.
