Description

An automatic detection and control system for an electrophoresis workshop Technical Field

[0001] This invention belongs to the technical field of degreasing agent detection devices, and particularly relates to an automatic detection and control system for an electrophoresis workshop. Background Technology

[0002] In industrial production, to extend the service life of workpieces, electrophoresis is often performed to form a uniform, dense, and strongly adhesive protective coating on their surface. Before electrophoresis, the workpiece surface must be cleaned with a degreasing agent to remove grease, dust, and other impurities; otherwise, the adhesion and protective effect of the electrophoretic coating will be severely affected.

[0003] Because degreasing agents are recyclable, they can be reused after filtration. However, with repeated use, the effective components in the degreasing agent are gradually consumed, and impurities accumulate, leading to a continuous decline in its cleaning ability. Continuing to use substandard degreasing agents will result in incomplete cleaning of the workpiece surface, causing quality problems such as blistering and peeling of the electrophoretic coating. Therefore, it is necessary to periodically test the reusable degreasing agents. Conductivity is a key indicator of degreasing agent performance; testing conductivity can accurately determine whether the degreasing agent still meets the workpiece cleaning requirements.

[0004] However, existing degreasing agent testing equipment has significant drawbacks: after each test, traditional testing instruments leave a large amount of degreasing agent and impurities on the testing head, and lack a dedicated cleaning device. In the next test, these residual substances mix into the degreasing agent being tested, interfering with the testing process and causing data deviations that fail to accurately reflect the actual performance of the degreasing agent.

[0005] Therefore, it is necessary to invent an automatic detection and control system for electrophoresis workshops to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an automatic detection and control system for an electrophoresis workshop, thereby resolving the issues raised in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic detection and control system for an electrophoresis workshop, comprising: a detector for detecting the conductivity of a degreasing agent, wherein the bottom of the detector is connected to a detection head via a data cable; a mounting frame for mounting the detector, wherein a detection base is connected to the bottom of the mounting frame; a detection cylinder placed on the detection base for holding the degreasing agent to be detected; and a cleaning device comprising a cleaning nozzle, a lifting assembly, and a water supply assembly, wherein the cleaning nozzle is disposed at the bottom of the detector, and a fixing rod is detachably connected between the rear side of the cleaning nozzle and the front side of the mounting frame; the cleaning nozzle is an annular tube with an opening on the front side, and water spray holes are evenly distributed on the bottom edge of the inner side of the cleaning nozzle; the lifting assembly is detachably connected between the detection head and the cleaning nozzle for driving the detection head to move vertically; and the water supply assembly is connected to the rear side of the cleaning nozzle for supplying water to the cleaning nozzle.

[0008] Furthermore, the lifting assembly includes a collar, a pull rod, a connecting rod, a top rod, and a guide rod. The collar is detachably sleeved on the detection head. The pull rod is L-shaped and vertically positioned on the side of the cleaning nozzle. A fixing block is slidably sleeved on the pull rod and fixedly connected to the side of the cleaning nozzle. The connecting rod is also L-shaped and fixedly connected to the bottom end of the pull rod away from the cleaning nozzle, with the bottom end of the pull rod flush with the top end of the detection head. The top rod is vertically fixedly connected to the top of the connecting rod. The guide rod is horizontally and vertically fixedly connected to the bottom end of the connecting rod near the detection head.

[0009] Furthermore, the water supply assembly includes a water tank, a water outlet pipe, a pressure valve, and a water receiving mechanism. The water tank is detachably installed on the front side of the mounting bracket. The water outlet pipe is connected between the bottom of the water tank and the cleaning nozzle. The pressure valve is installed on the water outlet pipe, and an extended valve stem is horizontally connected to the top of the pressure valve. The free end of the valve stem is aligned with the top of the push rod. When the push rod pushes the valve stem upward, the pressure valve can control the opening of the water outlet pipe. When the push rod separates from the valve stem, the pressure valve can automatically reset. The water receiving mechanism is located at the bottom of the water tank and is used to return the rinsed water to the detection cylinder when the cleaning nozzle rinses the detection head.

[0010] Furthermore, the water receiving mechanism includes a support plate, a water receiving box, a guide plate, and a return pipe. The support plate is horizontally fixedly connected to the front side of the mounting frame. A strip-shaped through hole is opened through the top of the support plate, and the length direction of the through hole is perpendicular to the front side of the mounting frame. The water receiving box is horizontally slidably installed on the top of the support plate, and the sliding direction of the water receiving box is parallel to the length direction of the strip-shaped hole. The guide plate is vertically fixedly connected to the side of the water receiving box near the guide rod, and a strip-shaped guide hole is opened through the guide plate on both sides. The end of the guide hole near the detection head is inclined downward, and a notch is opened at the bottom of the downwardly inclined end of the guide hole. The notch is directly opposite the guide rod, and the guide rod can enter the guide hole through the notch. The return pipe passes through the through hole and connects the side of the detection cylinder and the bottom of the water receiving box.

[0011] Furthermore, a limiting ring is fixedly connected to the top of the base, and the inner diameter of the limiting ring matches the outer diameter of the detection cylinder to limit the position of the detection cylinder.

[0012] Furthermore, a rubber pad is fixedly sleeved on the pull rod, the rubber pad is located on the top of the fixing block, and the rubber pad can contact the top of the fixing block.

[0013] Furthermore, the front of the water receiving box is designed to be open, the bottom inner wall of the water receiving box gradually slopes downward away from the detection head, and the top of the return pipe is directly opposite the lowest point of the bottom inner wall of the water receiving box.

[0014] Furthermore, in the initial state, the front side of the water receiving box is close to the vertical plane where the rear side of the detection head is located, and the water receiving box can move to the bottom position of the detection head under the cooperation of the guide rod and the guide plate.

[0015] Furthermore, the bottom of the water tank is higher than the top of the cleaning nozzle, and the top of the water tank is fitted with a cover with an air inlet.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention, by incorporating a cleaning device, ensures that when the lifting component raises the detection head after testing, it simultaneously triggers the water supply component to open. At this time, the cleaning nozzle, through evenly distributed water spray holes on the inner bottom, thoroughly rinses the detection head from multiple angles, completely removing residual degreasing agent and impurities from the surface. This prevents residual substances from mixing into the degreasing agent to be tested next time, eliminating deviations in test data at the source and ensuring that each test result accurately reflects the actual conductivity of the degreasing agent, providing precise data support for determining whether the degreasing agent meets the workpiece cleaning requirements. 2. This invention, by incorporating a water receiving mechanism, allows the water receiving box to collect the water after cleaning. The inner wall of the bottom of the water receiving box is inclined away from the detection head. Combined with the return pipe directly opposite the lowest point of the water receiving box, the rinsing water can be efficiently guided back to the detection cylinder, realizing the recycling of cleaning water and degreasing agent. This avoids water waste and reduces cost losses caused by degreasing agent loss during rinsing. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides an automatic detection and control system for an electrophoresis workshop, as shown in Figures 1 to 6, comprising: a detector 1, a mounting frame 3, a detection cylinder 5, and a cleaning device; the detector 1 is used to detect the conductivity of a degreasing agent, and the bottom of the detector 1 is connected to a detection head 2 via a data cable; the mounting frame 3 is used to mount the detector 1, and the bottom of the mounting frame 3 is connected to a detection base 4; the detection cylinder 5 is placed on the detection base 4 and is used to hold the degreasing agent to be tested; the cleaning device includes a cleaning nozzle 6, a lifting assembly, and a water supply assembly. The cleaning nozzle 6 is located at the bottom of the detector 1, and a fixing rod 7 is detachably connected between the rear side of the cleaning nozzle 6 and the front side of the mounting frame 3. The cleaning nozzle 6 is an annular tube with an opening on the front side, and water spray holes 8 are evenly distributed on the bottom edge of the inner side of the cleaning nozzle 6. The lifting assembly is detachably connected between the detection head 2 and the cleaning nozzle 6, and is used to drive... The detection head 2 moves vertically, and the water supply component is connected to the rear side of the cleaning nozzle 6 to supply water to the cleaning nozzle 6. During testing, the detection cylinder 5 is first placed in the limiting ring 24 of the detection base 4 to position the detection cylinder 5 accurately. Then, the degreasing agent to be tested is poured into the detection cylinder 5, and the liquid level of the degreasing agent is submerged at the bottom of the detection head 2. Subsequently, the detector 1 is started to test the degreasing agent in the detection cylinder 5. After the test is completed, the detection head 2 is pulled upward by the lifting component. When the top of the detection head 2 enters the inner area of ​​the cleaning nozzle 6, the water supply component is turned on. At this time, the water supply component can supply clean water into the cleaning nozzle 6 to achieve the rinsing operation of the detection head 2, avoid the degreasing agent and impurities remaining on the detection head 2, and thus ensure the accuracy of subsequent test data, providing a reliable basis for judging the performance of the degreasing agent.

[0021] As shown in Figures 2 to 6, the lifting assembly includes a collar 9, a pull rod 10, a connecting rod 11, a top rod 12, and a guide rod 13. The collar 9 is detachably fitted onto the detection head 2. The pull rod 10 is L-shaped and vertically positioned on the side of the cleaning nozzle 6. A fixing block 14 is slidably fitted onto the pull rod 10 and is fixedly connected to the side of the cleaning nozzle 6. The connecting rod 11 is also L-shaped and is fixedly connected to the bottom end of the pull rod 10 away from the cleaning nozzle 6, with the bottom end of the pull rod 10 flush with the top end of the detection head 2. The top rod 12 is vertically fixedly connected to the top of the connecting rod 11. The guide rod 13 is horizontally and vertically fixedly connected to the connecting rod 11 near the detection head 2. The water supply assembly includes a water tank 15, a water outlet pipe 16, a pressure valve 17, and a water receiving mechanism. The water tank 15 is detachably mounted on the front side of the mounting bracket 3. The water outlet pipe 16 connects the bottom of the water tank 15 to the cleaning nozzle 6. The pressure valve 17 is mounted on the water outlet pipe 16, and an extended valve stem 18 is horizontally connected to the top of the pressure valve 17. The free end of the valve stem 18 is aligned with the top of the push rod 12. When the push rod 12 pushes the valve stem 18 upward, the pressure valve 17 controls the opening of the water outlet pipe 16. When the push rod 12 separates from the valve stem 18, the pressure valve 17 automatically resets. The water receiving mechanism is located at the bottom of the water tank 15 and is used to rinse the cleaning nozzle 6. When cleaning the detection head 2, the rinsed water is returned to the detection cylinder 5. The bottom of the water tank 15 is higher than the top of the cleaning nozzle 6, and the top of the water tank 15 is equipped with a cover 26 with an air inlet, making it easy to open the cover 26 to add clean water to the water tank 15. The water receiving mechanism includes a support plate 19, a water receiving box 20, a guide plate 21, and a return pipe 22. The support plate 19 is horizontally fixed to the front side of the mounting bracket 3. A strip-shaped through hole is opened through the top of the support plate 19, and the length direction of the through hole is perpendicular to the front side of the mounting bracket 3. The water receiving box 20 is horizontally slidably installed on the top of the support plate 19, and the sliding direction of the water receiving box 20 is parallel to the length direction of the strip-shaped hole. The guide plate 21... The guide plate 21 is vertically fixed to the side of the water receiving box 20 near the guide rod 13, and the guide plate 21 has a strip-shaped guide hole 23 through it on both sides. The end of the guide hole 23 near the detection head 2 is inclined downward, and a notch is opened at the bottom of the downward inclined end of the guide hole 23. The notch is directly opposite the guide rod 13, and the guide rod 13 can enter the guide hole 23 through the notch. The return pipe 22 passes through the through hole and is connected between the side of the detection cylinder 5 and the bottom of the water receiving box 20. In the initial state, the front side of the water receiving box 20 is close to the vertical plane where the rear side of the detection head 2 is located, and the water receiving box 20 can move to the bottom position of the detection head 2 under the cooperation of the guide rod 13 and the guide plate 21.After the test is completed, as the pull rod 10 is pulled upward, the guide rod 13 gradually moves upward under the action of the pull rod 10. When the bottom of the test head 2 is aligned with the bottom of the guide plate 21, the guide rod 13 also moves upward to the notch of the guide hole 23. Then, as the pull rod 10 continues to move upward, the guide rod 13 moves upward with the connecting rod 11 and enters the guide hole 23 through the notch. At this time, as the guide rod 13 continues to rise, it moves along the inclined guide hole 23, thereby pushing the inner wall of the top of the guide hole 23 to collect water. As the water receiving box 20 moves forward along the support plate 19, and the top rod 12 just touches the valve rod 18 when the water receiving box 20 is about to move directly below the detection head 2, the top of the detection head 2 is also about to fully enter the cleaning nozzle 6. At this time, as the pull rod 10 continues to move upward, the top rod 12 can push the valve rod 18 upward, thereby opening the pressure valve 17. At this time, the water in the water tank 15 can flow into the cleaning nozzle 6 through the water outlet pipe 16. Then, the clean water entering the cleaning nozzle 6 can spray onto the surface of the detection head 2 through the spray hole 8, thereby achieving the cleaning of the detection head 2. The rinsing operation on the surface of probe 2 ensures its cleanliness and the accuracy of subsequent test results. During the cleaning process, the rinsed water drips down the surface of probe 2 into the water collection box 20 at its bottom. The water in the collection box 20 then flows back into the test cylinder 5 through the return pipe 22, thus preventing the degreasing agent from being wasted and dripping everywhere. After cleaning, the test cylinder 5 can be removed and the degreasing agent poured out. During the removal of the test cylinder 5, the water collection box 20 and... The friction between the support plates 19 keeps the water receiving box 20 stationary. Meanwhile, the pull rod 10 remains in its current position due to the obstruction of the guide rod 13 by the guide hole 23. After the degreasing agent inside the detection cylinder 5 is cleaned, the pull rod 10 is pressed down, causing it to move the guide rod 13 downwards. As the guide rod 13 moves downwards, it pushes the water receiving plate backwards through the squeezing force on the inner wall of the bottom of the guide hole 23, thus gradually resetting the water receiving box 20 and preparing it for the next test.

[0022] As shown in Figures 1 and 3, a limiting ring 24 is fixedly connected to the top of the base. The inner diameter of the limiting ring 24 matches the outer diameter of the detection cylinder 5, which is used to limit the position of the detection cylinder 5. By setting the limiting ring 24, the placement position of the detection cylinder 5 can be limited, ensuring that the detection head 2 can be accurately inserted into the detection cylinder 5 to complete the detection operation of the degreasing agent.

[0023] As shown in Figure 5, a rubber pad 25 is fixedly sleeved on the pull rod 10. The rubber pad 25 is located on the top of the fixed block 14 and can contact the top of the fixed block 14. When the pull rod 10 drives the detection head 2 to descend to the detection position, the rubber pad 25 contacts the top of the fixed block 14, which plays a buffering role, reduces the impact force of the descent of the detection head 2, protects the detection head 2 and the detection cylinder 5, and extends the service life of the equipment.

[0024] As shown in Figures 2 and 6, the front of the water receiving box 20 is designed to be open. The bottom inner wall of the water receiving box 20 gradually slopes downwards away from the detection head 2, and the top of the return pipe 22 is directly opposite the lowest point of the bottom inner wall of the water receiving box 20. By setting the bottom inner wall of the water receiving box 20 to a sloped state, when the cleaning water flows into the water receiving box 20, the cleaning water can quickly flow into the return pipe 22 along the bottom inner wall of the water receiving box 20, thereby avoiding the residue of cleaning water in the water receiving box 20.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
