Technical Field
[0001] The present application relates to the field of copper alloy tube processing technology, and in particular to a copper alloy tube internal lubrication device, method, system and storage medium. Background Art
[0002] Copper alloy tubes, which are light in weight, high in strength, and have good thermal conductivity, electrical conductivity, corrosion resistance and processing properties, are widely used as conductive components and instrument tubes in various devices in the fields of machinery, electrical engineering, electronics, etc.
[0003] During the production and use of copper alloy tubes, lubricating liquid needs to be supplied to the inside of the copper alloy tubes for subsequent processing. The general lubricating liquid supply method is mostly relatively simple, and the lubricating liquid is directly supplied to the copper tube. Moreover, since copper alloy tubes are generally long, during the internal lubrication process, the copper tube needs to be pulled from one end to the other end so that the internal lubrication operation can be better performed on the copper alloy tube.
[0004] Regarding the above-mentioned related technologies, the inventors believe that when users directly supply lubricating liquid to the inside of the copper tube, it is not clear whether the lubricating liquid is supplied in place during the lubrication process, which may easily lead to poor lubricating liquid coating and fail to achieve good use effect. There is still room for improvement. Summary of the Invention
[0005] In order to improve the problem that it is unclear whether the lubricating liquid is supplied in place during the lubrication process, which easily leads to poor lubricating liquid coating and inability to achieve good use effect, the present application provides a copper alloy tube lubrication device, method, system and storage medium.
[0006] In a first aspect, the present application provides a copper alloy tube internal lubrication device, which adopts the following technical solution:
[0007] A copper alloy tube internal lubrication device, comprising a base, an electric push rod and an inner bracket inserted into the copper alloy tube, the electric push rod is mounted on the base, the inner bracket is fixedly mounted on the push rod of the electric push rod, a liquid spray pipe connected to an external lubricating liquid barrel is mounted on the inner bracket, the liquid spray pipe is provided with nozzles evenly arranged along the length direction of the inner bracket, the nozzles are oriented toward and connected to the space between the inner bracket and the copper alloy tube, a heating plate is arranged along the length direction of the inner bracket, a breathable net is provided on the inner bracket for gas to pass through but liquid to not pass through, a sealed copper alloy tube is mounted on the inner bracket close to the electric push rod. One end of the push rod is installed on the copper alloy tube and a sealing plate is fixed to the copper alloy tube. A front baffle with the same size as the inner size of the copper alloy tube is installed on the inner bracket. The front baffle and the inner bracket are detachably connected. The front baffle has a glue hole. A sealing film is installed on the front baffle, which is located in the glue hole and seals the glue hole. The front baffle is provided at one end of the inner bracket away from the electric push rod. A pressure sensor for detecting the pressure in the glue hole is installed on the side of the front baffle away from the sealing plate. The contact of the pressure sensor is passed through the glue hole and abuts against the sealing film. The base is also provided with a rotating bracket that supports the copper alloy tube and rotates.
[0008] By adopting the above technical solution, the lubricating liquid is continuously added during the forward movement through the adapted inner bracket, and then the two sides are sealed, and a pressure detection device is set at one end for pressure detection, so as to detect whether the lubricating liquid is fully applied, thereby automatically judging whether the lubricating liquid is evenly applied, and then continuing to move forward when the lubricating liquid is evenly applied, thereby realizing the automation and uniformity of the lubricating liquid application, eliminating the need for manual operation by the user, and improving the efficiency of the lubricating liquid application.
[0009] In a second aspect, the present application provides a method for lubricating a copper alloy tube, which adopts the following technical solution:
[0010] A method for lubricating an inner portion of a copper alloy tube, applied to the aforementioned inner portion of a copper alloy tube lubricating device, comprising:
[0011] Get copper alloy pipe size information;
[0012] determining coating thickness information based on the copper alloy tube size information;
[0013] Calculating inner bracket size information based on coating thickness information and copper alloy tube size information;
[0014] Determine the front baffle number information and the inner bracket number information based on the copper alloy tube size information and the inner bracket size information;
[0015] Install the front baffle corresponding to the front baffle number information at the front end of the inner bracket corresponding to the inner bracket number information, and insert the installed inner bracket into the copper alloy tube to be coated with lubricating liquid and move forward along the length direction of the copper alloy tube size information;
[0016] Obtain pressure information in the glue hole on the front baffle;
[0017] Determine whether the pressure information is greater than 0;
[0018] If it is equal to 0, the lubricating liquid is sprayed from the nozzle of the inner bracket to the space between the inner bracket and the inner wall of the copper alloy tube;
[0019] If it is greater than 0, then the distance corresponding to the preset reasonable advancement distance information is advanced and the current distance information is accumulated;
[0020] When the current distance information is equal to the length in the copper alloy tube size information, the front baffle corresponding to the front baffle number information is dropped off and the inner bracket is retracted and detached from the copper alloy tube.
[0021] By adopting the above technical solution, the lubricating liquid is continuously added during the forward movement through the adapted inner bracket, and then the two sides are sealed, and a pressure detection device is set at one end for pressure detection, so as to detect whether the lubricating liquid is fully applied, thereby automatically judging whether the lubricating liquid is evenly applied, and then continuing to move forward when the lubricating liquid is evenly applied, thereby realizing the automation and uniformity of the lubricating liquid application, eliminating the need for manual operation by the user, and improving the efficiency of the lubricating liquid application.
[0022] Optionally, the method of spraying lubricating liquid from the nozzle of the inner bracket to between the inner bracket and the inner side wall of the copper alloy tube includes:
[0023] Before the reasonable forward advancement distance information is obtained, the electric push rod retracts and continuously obtains pressure information, which is defined as continuous pressure information;
[0024] Determining whether the continuous pressure information is equal to a preset full pressure threshold information;
[0025] If it is less than, the electric push rod will continue to retract;
[0026] If they are equal, the distance after retraction is defined as the return distance information;
[0027] Calculate cavity distance information based on current distance information and return distance information;
[0028] Calculate the corrected propulsion distance information according to the reasonable propulsion distance information and the cavity distance information;
[0029] Calculating missing lubricating fluid volume information based on coating thickness information, copper alloy tube size information, and cavity distance information;
[0030] Calculate the single lubricating fluid volume information based on coating thickness information, copper alloy tube size information and reasonable advancement distance information;
[0031] Calculate the single total lubricating fluid volume information according to the single lubricating fluid volume information and the empty lubricating fluid volume information;
[0032] After the forward correction distance information is obtained, a volume of lubricating liquid corresponding to the single total lubricating liquid volume information is sprayed from the nozzle of the inner bracket to between the inner bracket and the inner side wall of the copper alloy tube.
[0033] By adopting the above technical solution, the inner bracket is retracted to check whether the lubricating liquid is completely filled. When there is a gap inside, the lubricating liquid is gathered by squeezing, thereby removing the internal bubbles and improving the integrity and accuracy of the lubricating liquid filling.
[0034] Optionally, after the current corrected propulsion distance information is advanced, the method of spraying a volume of lubricating liquid corresponding to the single total lubricating liquid volume information from the nozzle of the inner bracket to between the inner bracket and the inner side wall of the copper alloy tube includes:
[0035] Determine the initial inner stent insertion size information according to the return distance information and the inner stent size information;
[0036] Calculate the final stent insertion size information based on the reasonable advancement distance information and the current distance information;
[0037] Determining insertion range information based on initial stent insertion size information and final stent insertion size information;
[0038] Determine the nozzle number and nozzle position that fall within the extending range information based on the preset nozzle number information, nozzle position information, and the mapping relationship between the nozzle number information and the nozzle position information, define the nozzle number as current nozzle number information, and define the nozzle position information corresponding to the current nozzle number information as current nozzle position information;
[0039] Determine whether the current nozzle position information exists;
[0040] If it exists, the first nozzle-adjacent distance information is determined according to the current nozzle position information and the initial inner bracket extension size information;
[0041] When the first nozzle advancing distance information is reached, the lubricating liquid having a volume corresponding to the single total lubricating liquid volume information is sprayed from the nozzle corresponding to the current nozzle number information to between the inner bracket and the inner wall of the copper alloy tube;
[0042] If it does not exist, the nozzle number and nozzle position closest to the extending range information are determined based on the mapping relationship between the nozzle number information and the nozzle position information, and the nozzle number is defined as the nearest nozzle number information, and the nozzle position information corresponding to the nearest nozzle number information is defined as the nearest nozzle position information;
[0043] Determine the second nozzle-adjacent distance information according to the nearest nozzle position information and the initial inner bracket extension size information;
[0044] When the second nozzle advancement distance information is advanced, the lubricating liquid having a volume corresponding to the single total lubricating liquid volume information is sprayed from the nozzle corresponding to the nearest nozzle number information to between the inner bracket and the inner side wall of the copper alloy tube.
[0045] By adopting the above technical solution, since the lubricating liquid itself has a certain viscosity, when the front baffle moves forward, the lubricating liquid itself lags behind the sliding distance of the front baffle, thereby generating a gap, and the gap is often located on the side close to the front baffle, so the lubricating liquid is injected from the side away from the front baffle, so that the lubricating liquid will flow to the side of the front baffle when filling, and all the gaps will pass through one side to fill all the gaps, thereby improving the accuracy of the lubricating liquid filling.
[0046] Optionally, when the first nozzle advancement distance information is advanced, the method of spraying a volume of lubricating liquid corresponding to the single total lubricating liquid volume information from the nozzle corresponding to the current nozzle number information to between the inner bracket and the inner side wall of the copper alloy tube includes:
[0047] Get the current ejection volume information;
[0048] The rapid supply quantity information is calculated based on the preset critical threshold quantity information and the single total lubricating fluid volume information;
[0049] Determine whether the current ejection volume information is greater than the rapid supply volume information;
[0050] If it is less than, it will be sprayed at the preset fast spray speed information;
[0051] If it is greater than, the spray is performed at the spray speed corresponding to the preset deceleration curve information and the pressure information is obtained;
[0052] When the pressure information is equal to the full pressure threshold information or the current ejection amount information is equal to the single total lubricating fluid volume information, the ejection is stopped.
[0053] By adopting the above technical solution, on the one hand, by first quickly spraying a certain amount, the filling space of the lubricating liquid can be quickly filled, thereby improving the efficiency of the spraying; on the other hand, by slowing down the spraying speed in the final stage, the flow is slower, and the gap in the middle is gradually filled. In the final stage, the outflow speed can be accurately controlled and the stop operation can be performed at any time, thereby improving the accuracy of the lubricating liquid outflow.
[0054] Optionally, a method for correcting single lubricating fluid volume information is also included, the method comprising:
[0055] After retracting to the return distance information, continue to retract and determine whether the return distance information remains unchanged;
[0056] If it changes, the seal failure information is output;
[0057] If it is unchanged, the actual volume reduction ratio information is determined based on the vacant lubricating fluid volume information and the single lubricating fluid volume information;
[0058] Calculating single-time corrected lubricating fluid volume information based on actual volume reduction ratio information and single-time lubricating fluid volume information;
[0059] Calculate the single corrected total lubricating fluid volume information according to the actual volume reduction ratio information and the single total lubricating fluid volume information;
[0060] After advancing the corrected propulsion distance information, the lubricant corresponding to the single corrected total lubricant volume information is sprayed out and then retracted to determine whether the return distance information does not exist;
[0061] If it does not exist, no correction is made;
[0062] If so, determine whether the actual volume reduction ratio information of the two times is consistent;
[0063] If they are consistent, the single lubricating fluid volume information is updated according to the single corrected lubricating fluid volume information;
[0064] If they do not match, an error message about the discharge volume will be output.
[0065] By adopting the above technical solution, the sealing space formed by the inner bracket is not sealed and the nozzle spray volume is inaccurate by continuing the return stroke, so that timely maintenance can be carried out in the case of non-sealing and inaccurate spray volume, thereby improving the working efficiency of the lubrication device; on the other hand, if the inaccurate spray volume is only a one-time abnormality, it may be that there are bubbles inside, so re-inspection is performed to determine whether the subsequent situation is accurate.
[0066] Optionally, when the first nozzle advancement distance information is advanced, the method of spraying a volume of lubricating liquid corresponding to the single total lubricating liquid volume information from the nozzle corresponding to the current nozzle number information to between the inner bracket and the inner side wall of the copper alloy tube includes:
[0067] Determine, based on a preset mapping relationship between the heating plate number information, the heating plate position information, and the heating plate number information and the heating plate position information, heating plate position information having a size smaller than that corresponding to the current nozzle position information, defining the heating plate position information as the current heating plate position information, and defining the heating plate number information corresponding to the current heating plate position information as the current heating plate number information;
[0068] Performing a matching analysis based on the heating temperature information stored in a preset heating database and the current heating plate number information and the current nozzle number information to determine the heating temperature corresponding to the current heating plate number information and the current nozzle number information, and defining the heating temperature as the current heating temperature information;
[0069] While the lubricating fluid of the volume corresponding to the single total lubricating fluid volume information is sprayed out from the nozzle corresponding to the current nozzle number information, heating is performed on each heating plate corresponding to the current heating plate number information according to the current heating temperature information.
[0070] By adopting the above technical solution, each area within the lubricating liquid interval is heated and distributed according to a certain temperature, so that the lubricating liquid in each area is heated to different temperatures, which not only ensures the fluidity of the lubricating liquid, but also ensures the viscosity of the lubricating liquid in the copper alloy tube when the inner bracket is detached.
[0071] Optionally, the method of heating on each heating plate corresponding to the current heating plate number information according to the current heating temperature information includes:
[0072] Determine the extrusion distance information according to the copper alloy tube size information and the inner bracket size information;
[0073] After selecting a direction from the preset extrusion direction information, the copper alloy tube is moved by the manipulator and feedback resistance information on the manipulator is obtained;
[0074] Determining whether the feedback resistance information is greater than the preset liquid resistance information;
[0075] If not, continue to filter an extrusion direction information;
[0076] If so, the feedback resistance information that is greater than the liquid resistance information is defined as abnormal feedback resistance information, and the extrusion direction information corresponding to the abnormal feedback resistance information is defined as abnormal extrusion direction information;
[0077] Calculating the rotation angle information based on the abnormal extrusion direction information and the preset heating plate direction information;
[0078] After the copper alloy tube is rotated according to the rotation angle information, it is heated on the heating plate corresponding to each current heating plate number information according to the current heating temperature information for the preset heating time information, and then an extrusion direction information is continuously screened and the feedback resistance information is re-determined whether it is greater than the liquid resistance information.
[0079] By adopting the above technical solution, the inner bracket is stirred in the copper alloy tube to determine the angle at which the internal hard block exists, and then heating is performed at the corresponding angle to make the lubricating fluid flow evenly, thereby improving the fluidity of the lubricating fluid.
[0080] In a third aspect, the present application provides a copper alloy tube lubrication system, which adopts the following technical solution:
[0081] A copper alloy tube lubrication system, comprising:
[0082] An acquisition module is used to obtain copper alloy tube size information, pressure information, current ejection volume information, and feedback resistance information;

[0084] The program in the processor memory can be loaded and executed by the processor to implement any of the above-mentioned control methods for lubricating the copper alloy tube.
[0085] By adopting the above technical solution, the lubricating liquid is continuously added during the forward movement through the adapted inner bracket, and then the two sides are sealed, and a pressure detection device is set at one end for pressure detection, so as to detect whether the lubricating liquid is fully applied, thereby automatically judging whether the lubricating liquid is evenly applied, and then continuing to move forward when the lubricating liquid is evenly applied, thereby realizing the automation and uniformity of the lubricating liquid application, eliminating the need for manual operation by the user, and improving the efficiency of the lubricating liquid application.
[0086] Fourthly, the present application provides a computer storage medium that can store corresponding programs and has the characteristics of fast interaction with memory big data.

[0104] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.
[0105] The present application embodiment discloses a method for lubricating a copper alloy tube. Figure 1 and Figure 2 A method for lubricating a copper alloy tube comprises:
[0106] Step 100: Obtain copper alloy tube size information.
[0107] The copper alloy tube size information is information about the size of the copper alloy tube 4. It can be obtained by manually inputting it into a corresponding system.
[0108] Step 101: Determine coating thickness information based on copper alloy tube size information.
[0109] The coating thickness information is information about the thickness of the coating inside the copper alloy tube 4. Here, it can be an artificially set thickness, or it can be information about the coating thickness calculated according to an artificially set ratio, for example, 5%.
[0110] Step 102: Calculate the inner bracket size information based on the coating thickness information and the copper alloy tube size information.
[0111] The inner bracket size information is information on the size of the inner bracket 3 .
[0112] like Figure 1As shown, to facilitate the application of lubricating liquid to the interior of the copper alloy tube 4, a copper alloy tube lubrication device is employed. The device comprises a base 1, an electric push rod 2, and an inner bracket 3. The electric push rod 2 is mounted on the base 1, and the inner bracket 3 is fixedly mounted on the electric push rod 2, so that the inner bracket 3 is pushed forward or backward by the electric push rod 2. The inner bracket 3 is similar in shape to the copper alloy tube 4. When the inner bracket 3 is inserted into the copper alloy tube 4, the two can be arranged in a concentric circle. A liquid spray pipe 31 is mounted within the inner bracket 3. The liquid spray pipe 31 has a plurality of nozzles 311 arranged evenly along the length and width of the inner bracket 3. The nozzles 311 open into the space between the inner bracket 3 and the copper alloy tube 4 and communicate with the space between the inner bracket 3 and the copper alloy tube 4, allowing the lubricating liquid within the liquid spray pipe 31 to be sprayed from the nozzles 311 into the space between the inner bracket 3 and the copper alloy tube 4. To allow air to be expelled smoothly when the lubricating liquid enters the space between the inner bracket 3 and the copper alloy tube 4, the inner bracket 3 is provided with a breathable mesh 333 that is permeable to gas but impermeable to liquid. To prevent the lubricating liquid from leaking out of the space between the inner bracket 3 and the copper alloy tube 4, a sealing plate 32 and a front baffle 33 are installed on both sides of the inner bracket 3. The sealing plate 32 is located on the side of the copper alloy tube 4 near the electric push rod 2 to seal the side of the copper alloy tube 4 near the electric push rod 2. The size of the sealing plate 32 is larger than that of the copper alloy tube 4. When the inner bracket 3 is inserted into the copper alloy tube 4, the sealing plate 32 abuts against the copper alloy tube 4 and is fixedly connected to the copper alloy tube 4. The fixed connection here can be a snap-on connection, that is, a portion of the inner bracket 3 snaps into the copper alloy tube 4 as it is extended. However, due to its large overall size, it is not possible to snap all the way in, so it is fixed to the copper alloy tube 4. The front baffle 33 is located on the side of the inner bracket 3 away from the electric push rod 2. The size of the front baffle 33 is the same as the inner size of the copper alloy tube 4, and can also be slightly larger than the inner size of the copper alloy tube 4. When the inner bracket 3 extends into the copper alloy tube 4, the front baffle 33 moves with the inner bracket 3 within the copper alloy tube 4. The front baffle 33 is detachably connected to the inner bracket 3.
[0113] Step 103: Determine the front baffle number information and the inner bracket number information based on the copper alloy tube size information and the inner bracket size information.
[0114] The front bezel number information is information about the number of the front bezel 33. The inner bracket number information is information about the number of the inner bracket 3.
[0115] Step 104: Install the front baffle 33 corresponding to the front baffle number information at the front end of the inner bracket 3 corresponding to the inner bracket number information and insert the installed inner bracket 3 into the copper alloy tube 4 to be coated with lubricant along the length direction of the copper alloy tube size information.
[0116] The inner bracket 3 and the front baffle 33 have many sizes. When a certain size is required, the corresponding inner bracket 3 can be installed on the electric push rod 2. Here, a robot can be used to control the installation of the inner bracket 3, and the installation method can be a threaded method.
[0117] Step 105 : Obtain pressure information in the glue-permeable hole 331 on the front baffle 33 .
[0118] The pressure information is the pressure information felt on the sealing film 332 in the glue hole 331. Figure 1 As shown, the front baffle 33 has a glue hole 331 and a sealing membrane 332. The sealing membrane 332 is installed in the glue hole 331 and is located on the side of the glue hole 331 closest to the sealing plate 32. A pressure sensor 34 is also installed on the front baffle 33. The pressure sensor 34 is located on the side of the front baffle 33 away from the sealing plate 32. The contact of the pressure sensor 34 is inserted into the glue hole 331 and abuts against the sealing membrane 332. The sealing membrane 332 has a certain degree of elasticity. Therefore, when the sealing membrane 332 deforms toward the side closer to the pressure sensor 34, a value is generated on the pressure sensor 34.
[0119] Step 106: Determine whether the pressure information is greater than 0.
[0120] The purpose of the judgment is to determine whether the space between the inner bracket 3 and the copper alloy tube 4 is filled with lubricating liquid.
[0121] Step 1061 : If it is equal to 0, the lubricating liquid is sprayed from the nozzle 311 of the inner bracket 3 to the space between the inner bracket 3 and the inner wall of the copper alloy tube 4 .
[0122] If it is equal to, it means that the interior is not yet full, and lubricating liquid can still be sprayed from the nozzle 311 of the inner bracket 3 to the space between the inner bracket 3 and the inner side wall of the copper alloy tube 4 for coating.
[0123] Step 1062: If it is greater than 0, then advance the distance corresponding to the preset reasonable advancement distance information and accumulate the current distance information.
[0124] The reasonable advancement distance information is the artificially set reasonable advancement distance away from the electric push rod 2. The current distance information is the advancement distance of the inner bracket 3 in the copper alloy tube 4, which can be used as a reference by the front baffle 33. If it is greater than 0, it means that the interior is full and it is possible to continue to move forward for the next coating.
[0125] Step 107 : When the current distance information is equal to the length in the copper alloy tube size information, the front baffle 33 corresponding to the front baffle number information is dropped off and the inner bracket 3 is retracted and separated from the copper alloy tube 4 .
[0126] When the farthest end of the copper alloy tube 4 is reached, it means that the coating on the last side has been reached. If the value detected at this time is greater than 0, it means that the coating has been completed. The inner bracket 3 can be retracted and detached from the copper alloy tube 4. In order to prevent the front baffle 33 from bringing out the lubricating liquid when retracting, it can be detached from the side of the copper alloy tube 4 away from the electric push rod 2.
[0127] Reference Figure 3 The method of spraying lubricating liquid from the nozzle 311 of the inner bracket 3 to the space between the inner bracket 3 and the inner side wall of the copper alloy tube 4 includes:
[0128] Step 200 : Before advancing a reasonable distance, the electric push rod 2 retracts and continuously acquires pressure information, which is defined as continuous pressure information.
[0129] The continuous pressure information is information about the pressure when the electric push rod 2 retracts.
[0130] Step 201: Determine whether the continuous pressure information is equal to the preset full pressure threshold information.
[0131] The full pressure threshold information is the critical value of pressure at which movement is impossible when the interior is full. This is a manually set critical value. If there is air inside, the front baffle 33 will retract when the electric push rod 2 retracts, squeezing the lubricant. When all the lubricant accumulates together, the pressure will continue to increase. At this time, in order to prevent the sealing membrane 332 from rupturing, a critical value is set to ensure the safety of the sealing membrane 332.
[0132] Step 2011: If it is less than, the electric push rod 2 continues to retract.
[0133] If it is less than, it means there are still gaps or bubbles inside, and it can continue to shrink.
[0134] Step 2012: If they are equal, the distance after retraction is defined as the return distance information.
[0135] The return distance information is information about the position after retraction. Similar to the current distance information, both are distance values within the copper alloy tube 4.
[0136] Step 202: Calculate cavity distance information based on current distance information and return distance information.
[0137] The cavity distance information is the distance between the current distance information and the return distance information, and is calculated by subtracting the return distance information from the current distance information.
[0138] Step 203: Calculate the corrected propulsion distance information based on the reasonable propulsion distance information and the cavity distance information.
[0139] The corrected advance distance information is the theoretically required advance distance from the current distance information to the return distance information. The calculation method is to add the two.
[0140] Step 204: Calculate the missing lubricating fluid volume information based on the coating thickness information, the copper alloy tube 4 size information, and the cavity distance information.
[0141] The missing lubricant volume information is the volume of lubricant required to fill the space corresponding to the cavity distance information, and is calculated by multiplying the cross-sectional area occupied by the coating thickness information by the cavity distance information.
[0142] Step 205: Calculate the single lubricating fluid volume information based on the coating thickness information, the copper alloy tube 4 size information, and the reasonable advancement distance information.
[0143] The single lubricant volume information is the information of the lubricant volume that needs to be replenished after the reasonable advancement distance information is advanced. The calculation method is the same as step 204 and will not be repeated here.
[0144] Step 206: Calculate the single total lubricating fluid volume information based on the single lubricating fluid volume information and the empty lubricating fluid volume information.
[0145] The total lubricant volume per trip is the volume of lubricant that needs to be replenished after the corrected distance is applied. It is calculated by adding the two.
[0146] Step 207 : After the forward corrected propulsion distance information is obtained, the lubricating liquid having a volume corresponding to the single total lubricating liquid volume information is sprayed from the nozzle 311 of the inner bracket 3 to the space between the inner bracket 3 and the inner wall of the copper alloy tube 4 .
[0147] By retracting the inner bracket 3, it is checked whether the lubricating liquid is completely filled. When there is a gap inside, the lubricating liquid is gathered by squeezing, thereby removing the internal bubbles and improving the integrity and accuracy of the lubricating liquid filling.
[0148] Reference Figure 4 The method of spraying a volume of lubricating liquid corresponding to the single total lubricating liquid volume information from the nozzle 311 of the inner bracket 3 to the space between the inner bracket 3 and the inner side wall of the copper alloy tube 4 after advancing the current corrected propulsion distance information includes:
[0149] Step 300: Determine initial inner stent insertion size information according to the return distance information and the inner stent size information.
[0150] The initial inner bracket insertion dimension information is the dimension information of the portion of the inner bracket 3 inside the copper alloy tube 4 at the return distance information. The length of the inner bracket dimension information is determined to be the value of the return distance information.
[0151] Step 301: Calculate the final stent extension size information based on the reasonable advancement distance information and the current distance information.
[0152] The final inner bracket insertion dimension information is the dimension information of the portion of the inner bracket 3 inside the copper alloy tube 4 when the current distance information is reasonably advanced forward by the distance information.
[0153] Step 302: Determine extension range information based on the initial stent extension size information and the final stent extension size information.
[0154] The extension range information is the portion of the newly added inner bracket 3 extending into the copper alloy tube 4 from the return distance information to the current distance information, and continues to advance the reasonable advancement distance information. The extension range information here is information on the range of the distance from the front baffle 33.
[0155] Step 303: Based on the preset nozzle number information, nozzle position information and the mapping relationship between the nozzle number information and the nozzle position information, determine the nozzle number and nozzle position that fall within the extension range information, define the nozzle number as the current nozzle number information, and define the nozzle position information corresponding to the current nozzle number information as the current nozzle position information.
[0156] The nozzle number information is the number information of the nozzle 311, as shown here Figure 1 As shown, nozzles 311 are arranged along the length of inner bracket 3. Therefore, the purpose of nozzle numbering is to identify the position of nozzle 311 on inner bracket 3. Nozzle position information refers to the position of nozzle 311. Current nozzle number information refers to the number of nozzles 311 located within the reach range information. Current nozzle position information refers to the position of nozzle 311 with the current nozzle number information. This information is used to determine whether a new nozzle 311 has entered the space between inner bracket 3 and copper alloy tube 4 to spray liquid.
[0157] Step 304: Determine whether the current nozzle position information exists.
[0158] Step 3041: If it exists, determine the first nozzle advancement distance information based on the current nozzle position information and the initial inner bracket 3 extension size information.
[0159] The first nozzle-approaching advance distance information is information about the distance required to advance from the return distance information to the appearance of the nozzle 311 corresponding to the current nozzle number information.
[0160] Step 3042: If it does not exist, determine the nozzle number and nozzle position closest to the extension range information based on the mapping relationship between the nozzle number information and the nozzle position information, define the nozzle number as the nearest nozzle number information, and define the nozzle position information corresponding to the nearest nozzle number information as the nearest nozzle position information.
[0161] The most recent nozzle number information is the number of the nozzle 311 already located between the copper alloy tube 4 and the inner bracket 3. The most recent nozzle position information is the position of the nozzle 311 corresponding to the most recent nozzle number information. If the most recent nozzle position information does not exist, it indicates that no new nozzle 311 has been added, and liquid can be sprayed from the most recently added nozzle 311.
[0162] Step 305 : When advancing the first nozzle advancing distance information, the lubricating liquid having a volume corresponding to the single total lubricating liquid volume information is sprayed from the nozzle 311 corresponding to the current nozzle number information to between the inner bracket 3 and the inner wall of the copper alloy tube 4 .
[0163] It should be noted that during the process of spraying lubricant from the nozzle 311 corresponding to the current nozzle number information at the first nozzle advance distance information, the inner bracket 3 is still advancing, so there is no need to wait until the inner bracket 3 reaches the final inner bracket 3 extension distance information before spraying liquid. The purpose of spraying liquid at the position of the current nozzle number information is to start injecting lubricant from the end farthest from the front baffle 33 and fill all gaps.
[0164] Step 306: Determine the second nozzle-adjacent advancement distance information based on the nearest nozzle position information and the initial inner bracket 3 extension size information.
[0165] The second nozzle-near advancement distance information is information about the distance required to advance from the return distance information to the nearest nozzle position information.
[0166] Step 307 : When advancing the second adjacent nozzle advancing distance information, the lubricating liquid having a volume corresponding to the single total lubricating liquid volume information is sprayed from the nozzle 311 corresponding to the nearest nozzle number information to between the inner bracket 3 and the inner side wall of the copper alloy tube 4 .
[0167] It should be noted that when the lubricating liquid is sprayed from the nozzle 311 corresponding to the nearest nozzle number information at the second nozzle advancement distance information, the inner bracket 3 is still advancing, so that the inner bracket 3 does not need to wait until the final inner bracket 3 extension size information is reached before starting to spray the liquid.
[0168] Among them, if the first nozzle-advancing distance information has not been reached, the lubricating liquid can also be sprayed at the nozzle 311 corresponding to the nearest nozzle number information, and then closed when the first nozzle-advancing distance information is reached.
[0169] Reference Figure 5The method of spraying lubricating liquid of a volume corresponding to the single total lubricating liquid volume information from the nozzle 311 corresponding to the current nozzle number information to the space between the inner bracket 3 and the inner side wall of the copper alloy tube 4 when the first nozzle advance distance information is advanced includes:
[0170] Step 400: Obtain current ejection volume information.
[0171] The information of the current amount of the nozzle sprayed can be obtained by providing a flow meter in the spray pipe 31 and measuring the flow rate.
[0172] Step 401: Calculate the rapid supply quantity information based on the preset critical threshold quantity information and the single total lubricating fluid volume information.
[0173] The critical threshold value information is the difference between the manually defined value and the total lubricant volume information for a single injection. The rapid supply volume information is the volume of lubricant that can be rapidly injected. The critical threshold value information is set here to prevent the total lubricant volume information from being exceeded due to a delay in closing the valve.
[0174] Step 402: Determine whether the current ejection volume information is greater than the rapid supply volume information.
[0175] Step 4021: If it is less than, spraying is performed at the preset fast spraying speed information.
[0176] The fast spray speed information is information about a faster spray speed, which is a manually set value.
[0177] Step 4022: If it is greater than, spray at the spray speed corresponding to the preset deceleration curve information and obtain pressure information.
[0178] The deceleration curve information is information about a curve showing a speed that gradually decreases from the discharge amount corresponding to the rapid supply amount information. The purpose of obtaining pressure information is to determine whether the deceleration curve information is accurate.
[0179] Step 403: Stop spraying when the pressure information is equal to the full pressure threshold information or the current spraying amount information is equal to the single total lubricating fluid volume information.
[0180] Reference Figure 6 , also including a method for correcting single lubricating fluid volume information, the method comprising:
[0181] Step 500: Continue to retract after retracting to the return distance information and determine whether the return distance information remains unchanged.
[0182] It should be noted that the retraction is continued after the return distance information, that is, the step is performed after the pressure information is equal to the full pressure threshold information.
[0183] Step 5001: If there is a change, output the seal failure information.
[0184] The seal failure message indicates a loss of sealing between the copper alloy tube 4 and the inner bracket 3. This message can be output as a textual reminder. If the message changes, it indicates that the tube can still move and retract even after the gas has been exhausted. However, since the liquid cannot be compressed, this indicates a leak. In this case, the seal between the copper alloy tube 4 and the inner bracket 3 is insufficient, and the seal failure message is output.
[0185] Step 5002: If unchanged, determine the actual volume reduction ratio information based on the vacant lubricating fluid volume information and the single lubricating fluid volume information.
[0186] The actual volume reduction ratio information is the ratio of the actual amount of liquid ejected from nozzle 311 to the theoretical amount. If it remains unchanged, it indicates that the interior is filled with lubricant and there are no gaps. However, since the gap corresponding to the missing lubricant volume information does not exist, it means that the lubricant has shrunk. However, this shrinkage here does not mean a literal contraction, but rather a decrease in volume. This may be due to thermal expansion and contraction, or it may be due to the presence of bubbles inside. However, when the container is placed, the bubbles are expelled and the container shrinks, so it is necessary to determine the shrinkage ratio.
[0187] Step 501: Calculate single-time corrected lubricating fluid volume information based on actual volume reduction ratio information and single-time lubricating fluid volume information.
[0188] The single corrected lubricant volume information is the actual volume information when the theoretical single lubricant volume information is injected. The calculation method is to multiply the two.
[0189] Step 502: Calculate the single corrected total lubricating fluid volume information based on the actual volume reduction ratio information and the single total lubricating fluid volume information.
[0190] The single corrected total lubricating fluid volume information is information on the amount that needs to be injected when the injected amount after contraction reaches the single total lubricating fluid volume information.
[0191] Step 503: After advancing the corrected propulsion distance information, the lubricant corresponding to the single corrected total lubricant volume information is sprayed out and then retracted to determine whether the return distance information does not exist.
[0192] The purpose of the judgment here is to determine whether there is shrinkage in the amount injected each time.
[0193] Step 5031: If it does not exist, the single lubricating fluid volume information is updated according to the single corrected lubricating fluid volume information.
[0194] If it does not exist, it indicates that the cause is shrinkage, and the lubricating fluid volume information can be updated according to a single correction.
[0195] Step 5032: If it exists, output the ejection amount error information.
[0196] The discharge amount error information is information indicating that the method of obtaining the discharge amount or the discharge amount is incorrect.
[0197] Reference Figure 7 The method of spraying lubricating liquid of a volume corresponding to the single total lubricating liquid volume information from the nozzle 311 corresponding to the current nozzle number information to the space between the inner bracket 3 and the inner side wall of the copper alloy tube 4 when the first nozzle advance distance information is advanced includes:
[0198] Step 600: Based on the preset mapping relationship between the heating plate number information, the heating plate position information, the heating plate number information and the heating plate position information, determine the heating plate position information that is smaller than the size corresponding to the current nozzle position information, define the heating plate position information as the current heating plate position information, and define the heating plate number information corresponding to the current heating plate position information as the current heating plate number information.
[0199] The heating plate number information is the number information of the heating plate 35 on the inner bracket 3 that heats the space between the copper alloy tube 4 and the inner bracket 3. The heating plate position information is the information of the position corresponding to the heating plate number information. The current heating plate number information is the number information of the heating plate 35 whose position is smaller than the size corresponding to the current nozzle position information, which is actually the heating plate 35 closer to the front baffle 33. The current heating plate position information is the information of the position corresponding to the current heating plate number information. Figure 1 As shown, there is a heating plate 35 on one side of the inner bracket 3 . The heating plate 35 is arranged along the length direction of the inner bracket 3 . The purpose of numbering the heating plates 35 is to determine the orientation of the heating plates 35 .
[0200] Step 601: Perform matching analysis based on the heating temperature information stored in the preset heating database and the current heating plate number information and the current nozzle number information to determine the heating temperature corresponding to the current heating plate number information and the current nozzle number information, and define the heating temperature as the current heating temperature information.
[0201] The current heating temperature information is information about the temperature that needs to be heated at the position of the heating plate 35 when the lubricating liquid is sprayed from the nozzle position, when the distance from the nozzle 311 is the distance between the two current heating plate number information and the current nozzle number information. The purpose of heating is to make the liquid at the end away from the nozzle 311 more fluid. The database stores the mapping relationship between the heating temperature information, the current heating plate number information and the current nozzle number information. The staff in this field will plan according to different situations to ensure that the temperature is set when the liquid in the entire copper alloy tube 4 has a certain fluidity. Here, generally, the farther the distance, the higher the temperature. The purpose is that on the one hand, the farther the lubricating liquid is, the worse its fluidity is. However, if all areas are set according to the farthest temperature, then when the inner bracket 3 needs to be detached from the copper alloy tube 4, it will take a longer time to wait for the fluidity of the lubricating liquid to deteriorate.
[0202] Step 602 : While the volume of lubricating fluid corresponding to the single total lubricating fluid volume information is sprayed out from the nozzle 311 corresponding to the current nozzle number information, heating is performed on each heating plate 35 corresponding to the current heating plate number information according to the current heating temperature information.
[0203] Reference Figure 8 The method of heating the heating plate 35 corresponding to each current heating plate number information according to the current heating temperature information includes:
[0204] Step 700: Determine extrusion distance information according to the size information of the copper alloy tube 4 and the size information of the inner bracket 3.
[0205] The extrusion distance information is the vertical distance between the inner bracket 3 and the inner wall of the copper alloy tube 4. Here, the copper alloy tube 4 and the inner bracket 3 are initially coaxially arranged, so the distance value is the difference between the two radii.
[0206] Step 701: After selecting a direction from the preset extrusion direction information, the copper alloy tube 4 is moved by a manipulator and feedback resistance information on the manipulator is obtained.
[0207] The feedback resistance information is information about the resistance to moving the inner bracket 3 felt by the manipulator.
[0208] Step 702: Determine whether the feedback resistance information is greater than the preset liquid resistance information.
[0209] The liquid resistance information is the resistance information when the interior is filled with a liquid having good fluidity. The resistance value here can be obtained by heating all the places inside the copper alloy tube 4.
[0210] Step 7021: If not, continue to filter an extrusion direction information.
[0211] Step 7022: If yes, the feedback resistance information that is greater than the liquid resistance information is defined as abnormal feedback resistance information, and the extrusion direction information corresponding to the abnormal feedback resistance information is defined as abnormal extrusion direction information.
[0212] If so, it means that there is resistance at this time, and the source of the resistance is generally the resistance formed by the solid matter that gradually solidifies in the lubricating fluid.
[0213] Step 703: Calculate the rotation angle information based on the abnormal extrusion direction information and the preset heating plate direction information.
[0214] The heating plate direction information is information about the direction in which the heating plate 35 was originally placed. As shown in the figure, the heating plate direction information is directly above and can be set to 0°. The rotation angle information is information about the angle required to rotate the solid object on the abnormal extrusion direction information to directly above the heating plate 35.
[0215] Step 704: After rotating the copper alloy tube 4 according to the rotation angle information, heat it on the heating plate 35 corresponding to each current heating plate number information according to the current heating temperature information for the preset heating time information, and then continue to screen an extrusion direction information and re-determine whether the feedback resistance information is greater than the liquid resistance information.
