Description

Technical Field

[0001] The invention relates to the field of stainless steel polishing, in particular to a polishing system for stainless steel products. Background Art

[0002] Stainless steel and aluminum alloy are both metal materials that are not easy to rust and can be stored for a long time in a humid environment. Since the hardness of stainless steel exceeds that of aluminum alloy, stainless steel is preferred when producing some equipment with force requirements.

[0003] After stainless steel products are processed, they need to be polished. The current polishing methods include physical polishing, chemical polishing and electrolytic polishing. Physical polishing is to polish the stainless steel surface with sandpaper or grinding wheel to make it smooth. Chemical polishing is to put the stainless steel into an acidic solution and make it smooth through acid corrosion. Electrolytic polishing is to put the stainless steel into an electrolyte, connect the stainless steel to a positive electrode and pass electricity, and connect it to the negative electrode in the electrolyte. The current oxidizes the metal ions on the surface of the stainless steel and dissolves into the electrolyte, making it smooth.

[0004] During the electrolytic polishing process, due to the different initial roughness of stainless steel products, the time required for electrolytic polishing is also different. Therefore, incomplete polishing often occurs, affecting subsequent processing. At the same time, this situation will also lead to increased difficulty and cost of subsequent quality inspection. Therefore, we proposed a polishing system for stainless steel products to solve the problem. Summary of the invention

[0017] The analysis module includes a water storage tank opened at the bottom of the trough, the inner wall of the water storage tank is fixedly connected to a positive electrode and a negative electrode, the positive electrode and the negative electrode are electrically connected to a signal transmitter, when the circuit is connected, the signal transmitter transmits a signal to the encoder, the positive electrode and the negative electrode are both at a certain distance from the bottom wall of the water storage tank, and some electrolyte needs to be stored before the positive electrode and the negative electrode are connected;

[0018] A collecting groove is provided at the opening of the water sump, and the collecting groove cuts off the bottom wall of the trough;

[0019] The material trough is annular and is divided into an electrolysis area, a water filtration area, a judgment area, a material unloading area, and a material loading area in a counterclockwise direction;

[0020] The proportions of the electrolysis area, water filtration area, judgment area, unloading area, and loading area are designed according to the original roughness of the workpiece and the roughness of the finished product to ensure sufficient electrolytic polishing time and water filtration time.

The current conductivity of the electrolyte is judged by the ammeter reading or the brightness of the LED lamp. The specific change standard is set by the technician according to the type of electrolyte.

[0031] 3. Beneficial effects

[0032] Compared with the prior art, the advantages of the present invention are:

[0033] (1) This solution controls polishing by using a control module, a basic module, a feeding module, a discharging module, a driving module, a power supply module, a positioning identification module and an analysis module. When in use, the feeding module is started first, and the workpiece to be processed is sent to the material trough by the feeding belt through the feeding port. The driving module is also started accordingly, and the turntable drives the electric rod to rotate around the material trough. When the displacement sensor senses that it is close to the feeding port, the electric rod controls the height of the chuck to clamp the workpiece in the material trough. The workpiece begins to slide along the material trough with the turntable until all the chucks hold the workpiece, and the feeding belt stops;

[0034] When the displacement sensor senses that the workpiece has entered the electrolytic chamber, the electric rod extends to insert the workpiece into the electrolyte. The power supply module energizes the electrolytic electrodes through the electrolytic power supply. The current flows through the workpiece, and electrolytic polishing begins. When the displacement sensor senses that the workpiece is about to leave the electrolytic cell, the electric rod retracts to pull the workpiece out of the electrolyte.

[0035] When the workpiece enters the water filtration area, the electrolyte adhering to the surface of the workpiece slides down the surface. Since the surface roughness of the workpiece is not necessarily the same, the speed at which the electrolyte slides down is also different. After leaving the water filtration area, the amount of electrolyte remaining on the surface of the workpiece is also different.

[0036] After the workpiece enters the judgment area, if there is still a large amount of electrolyte dripping, it means that the surface roughness of the workpiece is unqualified. The electrolyte flows into the water storage tank and accumulates. As the electrolyte covers the positive electrode and the negative electrode, the circuit is connected, and the signal transmitter feeds back the signal to the encoder. The encoder sets the program code for the chuck of the corresponding workpiece. The chuck does not release the workpiece, and the workpiece flows back to the electrolytic cell again to continue electrolytic polishing. If there is no electrolyte dripping or a small amount of electrolyte dripping, it means that the surface roughness of the workpiece is qualified, the circuit is always open, and the encoder does not mark the signal;

[0037] When the displacement sensor senses reaching the discharge port, the chuck releases the workpiece, and the workpiece slides from the discharge port to the discharge belt and is sent out. When the displacement sensor senses approaching the feed port, the feed belt feeds a workpiece;

[0038] In this way, the equipment can automatically judge the polishing effect of the workpiece, which is more intelligent and convenient, conforming to the trend of industrial automation development. It can also provide data support for subsequent equipment debugging. At the same time, workpieces that do not achieve the set polishing effect can be reworked to ensure the quality of workpiece processing.

[0039] (2) By setting multiple negative electrodes, when in use, the rougher the workpiece surface, the more electrolyte will remain on the workpiece surface, the more electrolyte will accumulate in the water storage tank, the more negative electrodes will be submerged, and the more signals will be sent by the signal transmitter. In this way, the encoder controls the time of the secondary electrolytic polishing of the workpiece according to the number of signals received from the signal transmitter, prevents excessive polishing, and further improves the polishing quality of the workpiece.

[0040] (3) By opening a drainage channel at the bottom of the water storage tank, when the workpiece enters the judgment area, the workpiece presses the pressure block downward, and the pressure block pushes the sealing member to close the drainage channel, so that the electrolyte can be stored. After the workpiece leaves the judgment area, the elastic member pulls the sealing member to reset, the drainage channel is opened, and the stored electrolyte flows out. This ensures that the judgment of each workpiece is not affected by the previous one, making the judgment result more accurate.

[0041] (4) By adding a thickener to the electrolyte, the electrolyte has stronger adhesion. In this way, when processing workpieces with small original roughness and even smaller product roughness, the electrolyte will not slide off quickly, preventing the situation where no electrolyte can adhere to the judgment area regardless of whether the roughness is qualified. This makes the equipment more comprehensive and has a wider range of applications.

[0042] (5) Blow air to the workpiece surface through the air slot to accelerate the slide of the electrolyte. When the displacement sensor senses that the workpiece enters the water filter area, the blower blows relatively soft air through the air slot according to demand to accelerate the slide of the electrolyte. This can prevent a large amount of electrolyte from remaining in the judgment area when processing workpieces with large original roughness and product roughness, regardless of whether the roughness is qualified. This makes the equipment more comprehensive and has a wider range of applications.

[0043] After the displacement sensor senses that the workpiece has entered the judgment area, the blower blows relatively strong wind through the air slot, causing all the residual electrolyte on the surface of the workpiece to slide off. This makes the judgment faster, the results more accurate, the performance more significant, and also avoids the waste of electrolyte.

[0044] (6) A portion of the electrolyte discharged from the drainage channel is intercepted through the S-shaped water trap. When the electrolyte is discharged from the water storage tank, the electrolyte flows into the electrolytic cell from the drainage channel, but a small portion remains in the water trap. In this way, the two energized electrodes are connected, and the reaction device is energized to react. The reaction intensity is affected by the conductive effect of the electrolyte. In this way, the use of the electrolyte can be clearly and conveniently judged, and it can be replaced in time when the efficiency decreases, thereby ensuring the quality of electrolytic polishing;

[0045] At the same time, since the reaction equipment is in a normally open state, it is more convenient to observe;

[0046] When the water tank discharges the electrolyte again, the new electrolyte entering the water trap will flush away the existing electrolyte, thus ensuring that the data of each test is not affected by the previous one. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The power supply module includes an equipment driving power supply and an electrolytic power supply. The top of the workpiece 9 is connected to the electrolytic electrode. The equipment driving power supply supplies power to the feeding module, the discharging module, the driving module, the positioning identification module, and the analysis module. The electrolytic power supply is connected to the electrolytic electrode to supply power for the electrolytic polishing of the workpiece 9.

[0068] The positioning and identification module includes a displacement sensor and an encoder. The displacement sensor is located in the conductive rod 7. The displacement sensor is used to determine the positions of the electric rod 7, the chuck 8 and the workpiece 9. The encoder sets a program code for the chuck 8 of the workpiece 9 at the corresponding position according to the feedback from the analysis module, and controls the chuck 8 to release the workpiece 9 according to the set program.

[0069] The analysis module includes a water storage tank 10 opened at the bottom of the material tank 2, the inner wall of the water storage tank 10 is fixedly connected to the positive electrode 12 and the negative electrode 13, the negative electrode 13 is electrically connected to the signal transmitter, when the circuit is connected, the signal transmitter transmits a signal to the encoder, the positive electrode 12 and the negative electrode 13 are both at a certain distance from the bottom wall of the water storage tank 10, and some electrolyte needs to be stored to connect the positive electrode 12 and the negative electrode 13;

[0070] A collecting groove 11 is provided at the opening of the water trough 10, and the collecting groove 11 cuts off the bottom wall of the material trough 2;

[0071] The material trough 2 is annular, and is divided into an electrolysis area, a water filtration area, a judgment area, a material unloading area, and a material loading area in a counterclockwise direction;

[0072] The proportions of the electrolytic area, water filtration area, judgment area, material unloading area, and material loading area are designed according to the original roughness of the workpiece and the roughness of the finished product to ensure sufficient electrolytic polishing time and water filtration time;

[0073] Polishing is controlled by using a control module, a basic module, a feeding module, a discharging module, a driving module, a power supply module, a positioning identification module and an analysis module. When in use, the feeding module is started first, and the workpiece 9 to be processed is sent to the material trough 2 by the feeding belt through the feeding port 5, and the driving module is also started accordingly, and the turntable 6 drives the electric rod 7 to rotate around the material trough 2. When the displacement sensor senses that the electric rod 7 is close to the feeding port 5, the electric rod 7 controls the height of the chuck 8 to clamp the workpiece 9 in the material trough 2, and the workpiece 9 begins to be carried by the turntable 6 to slide along the material trough 2 until all the chucks 8 hold the workpiece 9, and the feeding belt stops;

[0074] When the displacement sensor senses that the workpiece 9 enters the electrolytic chamber 3, the electric rod 7 extends to insert the workpiece 9 into the electrolyte, and the power supply module energizes the electrolytic electrode through the electrolytic power supply, and the current flows through the workpiece 9, and electrolytic polishing begins. After the displacement sensor senses that the workpiece is about to leave the electrolytic cell 3, the electric rod 7 retracts to pull the workpiece 9 out of the electrolyte;

[0075] When the workpiece 9 enters the water filtering area, the electrolyte adhered to the surface of the workpiece 9 slides down along the surface. Since the surface roughness of the workpiece 9 is not necessarily the same, the speed at which the electrolyte slides down is also different. After leaving the water filtering area, the amount of electrolyte remaining on the surface of the workpiece 9 is also different.

[0076] After the workpiece 9 enters the judgment area, if there is still a large amount of electrolyte dripping, it means that the surface roughness of the workpiece 9 is unqualified. The electrolyte flows into the water storage tank 10 and accumulates. As the electrolyte covers the positive electrode 12 and the negative electrode 13, the circuit is connected, and the signal transmitter feeds back the signal to the encoder. The encoder sets the program code for the chuck 8 corresponding to the workpiece 9. The chuck 8 does not release the workpiece 9, and the workpiece 9 flows back to the electrolytic cell 3 again to continue electrolytic polishing. If there is no electrolyte dripping or a small amount of electrolyte dripping, it means that the surface roughness of the workpiece 9 is qualified, the circuit is always open, and the encoder does not mark the signal;

[0077] When the displacement sensor senses reaching the discharge port 4, the chuck 8 releases the workpiece 9, and the workpiece 9 slides from the discharge port 4 to the discharge belt and is sent out. When the displacement sensor senses approaching the feed port 5, the feed belt feeds a workpiece 9;

[0078] In this way, the device can automatically judge the polishing effect of the workpiece 9, which is more intelligent and convenient, conforms to the trend of industrial automation development, and can also provide data support for subsequent equipment debugging. At the same time, the workpiece 9 that does not reach the set polishing effect can be reworked to ensure the quality of the workpiece 9 processing.

[0079] The electrolytic cell 3 is wrapped around the outside of the electrolytic area of ​​the material tank 2. The depth of the electrolytic cell 3 is more than twice the depth of the material tank 2. The width of the material tank 2 is greater than the workpiece 9, thus ensuring the movable space of the workpiece so that it can be completely immersed in the electrolyte.

[0080] The bottom surface of the water filtering area of ​​the material trough 2 is inclined toward the electrolytic cell 3, so that the electrolyte dripping into the material trough 2 along the surface of the workpiece 9 can flow back into the electrolytic cell 3, avoiding loss and waste of the electrolyte.

[0081] The water collection tank 10 is located in the judgment area of ​​the material tank 2, and the bottom surface of the judgment area of ​​the material tank 2 is inclined toward the water collection tank 10, so as to facilitate the collection of electrolyte.

[0082] Further: the positive electrode 12 and the negative electrode 13 are symmetrically distributed with respect to the central axis width of the water storage tank 10, two to ten negative electrodes 13 are provided, and the negative electrodes 13 are evenly distributed from top to bottom along the inner wall of the water storage tank 10, and each negative electrode 13 is connected to a signal transmitter, and the encoder controls the extension time of the electric rod 7 in the electrolytic cell according to the number of signals received from the signal transmitter, and the positive electrode 12 and the lowest negative electrode 13 are at the same height;

[0083] By setting multiple negative electrodes 13, when in use, the rougher the surface of the workpiece 9, the more electrolyte will remain on the surface of the workpiece 9, the more electrolyte will accumulate in the water storage tank 10, the more negative electrodes 13 will be submerged, and the more signals will be sent by the signal transmitter. In this way, the encoder controls the time of the secondary electrolytic polishing of the workpiece according to the number of signals received from the signal transmitter, prevents excessive polishing, and further improves the polishing quality of the workpiece.

[0084] Furthermore, a drainage channel 14 is provided on the bottom wall of the water trough 10, the top of the drainage channel 14 is covered with a plugging member 15, a sealing gasket is provided on the bottom surface of the plugging member 15, a pressure block 16 is fixedly connected to the top of the plugging member 15, an elastic member 17 is fixedly connected between the plugging member 15 and the inner wall of the water trough 10, and the weight of the plugging member 15 below the elastic member 17 is greater than the weight of the plugging member 15 above the elastic member 17, thereby ensuring the stability of the plugging member 15;

[0085] By opening a drainage channel 14 at the bottom of the water storage tank 10, when the workpiece 9 enters the judgment area, the workpiece 9 presses the pressure block 16 downward, and the pressure block 16 pushes the blocking member 15 to close the drainage channel 14, so that the electrolyte can be stored. After the workpiece 9 leaves the judgment area, the elastic member 17 pulls the blocking member 15 to reset, the drainage channel 14 is opened, and the stored electrolyte flows out, thereby ensuring that the judgment of each workpiece 9 is not affected by the previous one, making the judgment result more accurate.

[0086] The drain channel 14 is connected to the electrolytic cell 3 , and the pressing block 16 extends out of the water storage tank 10 , and the extended portion is configured as an arc surface to facilitate downward squeezing.

[0087] Furthermore, a thickener is added to the electrolyte, and the thickener may be an organic salt, an inorganic salt, or a lipid;

[0088] By adding thickener to the electrolyte, the electrolyte has stronger adhesion. In this way, when processing workpieces with small original roughness and smaller product roughness, the electrolyte will not slide off quickly, preventing the situation where no electrolyte can adhere to the judgment area regardless of whether the roughness is qualified. This makes the equipment more comprehensive and has a wider range of applications.

[0089] See also Figure 7 , a polishing system for stainless steel products, further comprising a gas supply module;

[0090] The air supply module includes an air groove 18 opened at the bottom of the chuck 8, and the air supply module also includes an air pipe 19 connected to the top of the chuck 8. One end of the air pipe 19 is connected to the air groove 18, and the other end is connected to the blower. The exhaust volume of the blower is constantly changing;

[0091] Air is blown to the surface of the workpiece 9 through the air slot 18 to accelerate the slide of the electrolyte. When the displacement sensor senses that the workpiece has entered the water filtering area, the blower blows relatively soft air through the air slot 18 as needed to accelerate the slide of the electrolyte. This can prevent a large amount of electrolyte from being retained in the judgment area regardless of whether the roughness is qualified when processing workpieces with large original roughness and product roughness. This makes the equipment more comprehensive and has a wider range of applications.

[0092] After the displacement sensor senses that the workpiece has entered the judgment area, the blower blows relatively strong wind through the air groove 18, causing all the electrolyte remaining on the surface of the workpiece 9 to slide off. This makes the judgment faster, the results more accurate, the performance more significant, and also avoids the waste of electrolyte.

[0093] The opening of the air groove 18 is inclined toward the workpiece 9 so that the airflow can act on the workpiece 9 better.

[0094] See also Figure 8 , a polishing system for stainless steel products, further comprising a detection module;

[0095] The detection module includes an S-shaped water trap 20 arranged in the discharge channel 14. Two powered electrodes 21 that do not contact each other are arranged on the inner wall of the water trap 20. The two powered electrodes 21 are connected to a power supply, a regulator, and a reaction device. The reaction device can be an ammeter or an LED lamp. The current conductivity of the electrolyte is judged by the ammeter reading or the brightness of the LED lamp. The specific change standard is set by the technician according to the type of electrolyte.

[0096] The electrolyte discharged from the drainage channel 14 is intercepted by the S-shaped water trap 20. When the electrolyte is discharged from the water storage tank 10, the electrolyte flows into the electrolytic cell from the drainage channel 14, but a small part remains in the water trap 20. In this way, the two powered electrodes 21 are connected, and the reaction device is powered on to react. The reaction intensity is affected by the conductive effect of the electrolyte. In this way, the use of the electrolyte can be clearly and conveniently judged, and it can be replaced in time when the effect decreases, thereby ensuring the quality of electrolytic polishing.

[0097] At the same time, since the reaction equipment is in a normally open state, it is more convenient to observe;

[0098] When the water storage tank 10 discharges the electrolyte again, the electrolyte newly entering the water trap 20 will flush away the original electrolyte, thus ensuring that the test data of each time is not affected by the previous test data.

[0099] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
