Description

Technical Field

[0001] This utility model relates to the technical field of circuit board etching solution concentration testers, specifically a circuit board etching solution concentration tester. Background Technology

[0002] Circuit board etching is a key process in the electronics manufacturing industry. The concentration of the etching solution has a crucial impact on the etching quality and precision of the circuit board. Accurately measuring the etching solution concentration is a key step in ensuring the stability of the etching process and improving the production quality of circuit boards.

[0003] When using existing circuit board etching solution concentration testers...

[0004] (1) The detection probe may be fixed in position, which makes it difficult to adapt to the detection needs of etching solutions at different depths and positions, resulting in inaccurate and incomplete detection results;

[0005] (2) There is a lack of effective fixation and protection measures for the etching solution sample container to be tested. It is easy to shake or tip over during the test, which affects the normal progress of the test.

[0006] To address the above problems, this utility model provides a circuit board etching solution concentration tester. Utility Model Content

[0007] The purpose of this invention is to provide a circuit board etching solution concentration tester. This invention improves the accuracy and stability of the test by using an adjustable detection mechanism and a stable sample fixing mechanism, thereby solving the problems of insufficient fixed position of the detection probe and insufficient protection of the sample container.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a circuit board etching solution concentration tester, comprising a fixed base and a concentration adjustment test component, wherein the concentration adjustment test component is fixedly connected to the edges on both sides of the top of the fixed base, and the concentration adjustment test component comprises a fixed frame fixedly connected to the edges on both sides of the top of the fixed base;

[0009] A protective box is fixedly connected to the middle of the top of the fixed frame, and the body of the etching solution concentration tester is fixedly connected inside the protective box. A fixed frame is fixedly connected to the middle of the bottom of the fixed frame, and a motor box is fixedly connected to the inner top wall of the fixed frame. A servo motor is fixedly connected inside the motor box.

[0010] Furthermore, a transmission rod is fixedly connected to the output end of the servo motor, and a threaded rod is fixedly connected to one end of the transmission rod, thereby converting the rotational motion of the servo motor into the linear motion of the threaded rod, thus providing power for the lifting and lowering of the probe head.

[0011] Furthermore, a connecting rod is threaded to the bottom end of the threaded rod, and a sliding plate is fixedly connected to the bottom end of the connecting rod. The sliding plate is slidably connected to the inner wall of the fixed frame, so that the sliding plate can slide up and down along the inner wall of the fixed frame under the drive of the threaded rod, thereby driving the probe rod and probe head to accurately adjust their positions.

[0012] Furthermore, a probe rod is fixedly connected to the middle of the bottom end of the sliding plate, a probe head is fixedly connected to the bottom end of the probe rod, and a transmission line is fixedly connected to the top end of one side of the probe rod. One end of the transmission line is fixedly connected to one side of the bottom end of the etching solution concentration tester body, thereby achieving the function of transmitting the etching solution concentration signal detected by the probe head to the etching solution concentration tester body for processing and display via the transmission line.

[0013] Furthermore, a fixing component is fixedly connected to the middle of the top of the fixing base. The fixing component includes a connecting frame fixedly connected to the middle of the top of the fixing base. Protective posts are fixedly connected to both sides of the inner wall of the connecting frame, which achieves the function of providing an installation position and protection for the hydraulic rod body, while enhancing the structural stability of the connecting frame.

[0014] Furthermore, a hydraulic rod body is fixedly connected inside the protective column, and a clamping plate is fixedly connected to one end of the hydraulic rod body. The clamping plate is slidably connected to the inner wall of the connecting frame, so that the clamping plate can slide on the inner wall of the connecting frame by extending and retracting the hydraulic rod body, thereby achieving the function of clamping and fixing the etching solution sample container placed in the connecting frame.

[0015] Furthermore, damping expansion joints are fixedly connected to both sides of the clamping plate surface, and shock-absorbing plates are fixedly connected to the surface of the damping expansion joints. This achieves the effect of shock absorption and buffering through the damping expansion joints and shock-absorbing plates when clamping the sample container, reducing the impact of external vibrations on the sample container and preventing the container from breaking or the etching solution from splashing out.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a circuit board etching solution concentration tester.

[0018] (1) By adjusting the settings of the concentration test component, when the personnel operate the device, the servo motor can be started according to the specific situation of the etching solution sample. The probe head can be moved up and down through the transmission rod, threaded rod and other components, so that it can be accurately inserted into the etching solution at different depths for detection, thereby improving the accuracy and adaptability of the detection.

[0019] (2) By setting the fixed components, when the personnel operate the device, the etching solution sample container is placed in the connecting frame, the hydraulic rod body is activated, and the clamping plate clamps the container. At the same time, the damping expansion joint and the shock absorption plate can effectively buffer external vibrations, ensuring that the sample container remains stable during the detection process, and avoiding the situation where the detection results are affected by the shaking or tipping of the container.

[0030] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:

[0031] The output end of the servo motor 206 is fixedly connected to the transmission rod 207, and one end of the transmission rod 207 is fixedly connected to the threaded rod 208. The purpose of this design is to use the rotational power output by the servo motor 206 to transmit to the threaded rod 208 through the transmission rod 207, converting the circumferential motion of the motor into the rotational motion of the threaded rod 208, providing a power source for the lifting and lowering of the detection mechanism, and facilitating flexible adjustment of the detection position according to the depth of the etching solution sample.

[0032] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0033] The bottom end of the threaded rod 208 is threadedly connected to a connecting rod 209, and the bottom end of the connecting rod 209 is fixedly connected to a sliding plate 210. The sliding plate 210 is slidably connected to the inner wall of the fixed frame 204. The purpose of this design is that when the threaded rod 208 rotates, the threaded engagement drives the connecting rod 209 to move along the axis of the threaded rod 208, thereby enabling the sliding plate 210 to slide stably on the inner wall of the fixed frame 204, realizing the precise lifting and lowering of the probe rod 211 and the probe head 212, and ensuring that the probe head 212 can be accurately inserted into the etching solution to a suitable depth for detection.

[0034] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0035] A probe rod 211 is fixedly connected to the middle of the bottom of the sliding plate 210. A probe head 212 is fixedly connected to the bottom of the probe rod 211. A transmission line 213 is fixedly connected to the top of one side of the probe rod 211. One end of the transmission line 213 is fixedly connected to one side of the bottom of the etching solution concentration tester body 203. The purpose of this design is to collect etching solution concentration data in real time after the probe head 212 is inserted into the etching solution. The probe rod 211 plays the role of supporting and protecting the probe head 212. The collected data is quickly and stably transmitted to the etching solution concentration tester body 203 through the transmission line 213 for analysis and processing, and finally the etching solution concentration detection result is obtained.

[0036] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0037] A fixing component 3 is fixedly connected to the middle of the top of the fixing base 1.

Protective posts 302 are fixedly connected to both sides of the inner wall of the connecting frame 301. The purpose of this design is that the connecting frame 301 provides a placement space for the etching solution sample container. The protective posts 302 provide an installation base for the hydraulic rod body 303 on the one hand, and enhance the structural strength and stability of the connecting frame 301 on the other hand, preventing the fixing component 3 from deforming during operation and ensuring reliable fixation of the sample container.

[0038] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0039] A hydraulic rod body 303 is fixedly connected inside the protective column 302. A clamping plate 304 is fixedly connected to one end of the hydraulic rod body 303. The clamping plate 304 is slidably connected to the inner wall of the connecting frame 301. The purpose of this design is to control the extension and retraction of the hydraulic rod body 303 to drive the clamping plate 304 to slide on the inner wall of the connecting frame 301, thereby achieving adaptive clamping and fixing of etching solution sample containers of different sizes, ensuring that the sample containers will not shake or tip over during the detection process, and improving the stability and accuracy of the detection process.

[0040] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0041] Damping expansion joints 305 are fixedly connected to both sides of the surface of the clamping plate 304, and shock-absorbing plates 306 are fixedly connected to the surface of the damping expansion joints 305. The purpose of this design is that when the clamping plate 304 clamps the sample container, the damping expansion joints 305 and the shock-absorbing plates 306 play a buffering and shock-absorbing role, reducing the impact of external vibration on the sample container, while avoiding direct rigid contact between the clamping plate 304 and the sample container to prevent damage to the container, thus protecting the integrity of the sample container and the stability of the etching solution sample.

[0042] Working principle: In use, first place the etching solution sample container in the connecting frame 301, start the hydraulic rod body 303 to push the clamping plate 304 to slide. Utilize the buffering effect of the damping telescopic device 305 and the shock-absorbing plate 306 to firmly clamp the sample container. Then, according to the depth of the etching solution in the container, start the servo motor 206. The servo motor 206 drives the transmission rod 207 and the threaded rod 208 to rotate. The threaded rod 208 causes the sliding plate 210 to rise and fall along the inner wall of the fixed frame 204 through the connecting rod 209, thereby driving the probe rod 211 and the probe head 212 to move to the appropriate detection position. The probe head 212 collects the etching solution concentration data, which is transmitted to the etching solution concentration tester body 203 via the transmission line 213 for analysis and processing. Finally, the etching solution concentration detection result is displayed. After the detection is completed, reverse the operation of the servo motor 206 and the hydraulic rod body 303 to make the probe head 212 rise and reset, release the clamping plate 304, and remove the sample container.
