Description

Technical Field

[0001] This application relates to the field of bearing inner ring processing technology, and particularly relates to a bearing inner ring feeding method, system, storage medium and intelligent terminal. Background Art

[0002] There are two grinding methods for the raceways of the inner ring of tapered roller bearings, namely convex raceways and straight raceways, which have different effects on product performance. It is necessary to understand the respective characteristics of the quality control of the raceway size and shape and the respective characteristics of the grinding methods.

[0003] In related technologies, for example, the Chinese patent with the publication number CN104175194A discloses an automatic grinding production line and method for the inner and outer rings of tapered roller bearings. The automatic production line consists of a rough grinding machine, a semi-finish grinding machine, a finish grinding machine, a lifting device, a transportation device, etc. The inner ring and outer ring grinding processes of the entire grinding production line are: rough grinding, semi-finish grinding and finish grinding.

[0004] Regarding the above related technologies, the inventors believe that before the semi-finish grinding or finish grinding process, it is necessary to conduct quality inspections on the products of rough grinding and semi-finish grinding, and this process often requires manual inspection, which is time-consuming and laborious, and there is still room for improvement. Summary of the Invention

[0005] In order to improve the problem that quality inspections need to be carried out on the products of rough grinding and semi-finish grinding, and this process often requires manual inspection, which is time-consuming and laborious, this application provides a bearing inner ring feeding method, system, storage medium and intelligent terminal.

[0006] In a first aspect, this application provides a bearing inner ring feeding method, adopting the following technical solution:

[0007] A bearing inner ring feeding method includes:

[0008] Obtain weight information and a preset feeding signal, and define the weight information before obtaining the feeding signal as the current weight information;

[0009] When the feeding signal is obtained, calculate the required weight information according to the current weight information and the preset full-load weight information;

[0010] Calculate the bearing inner ring quantity information according to the required weight information and the preset unit bearing inner ring weight information;

[0011] Perform matching analysis according to the test probe group number information stored in the preset test probe group database and the bearing inner ring quantity information to determine the set of test probe group numbers corresponding to the bearing inner ring quantity information, and define this set of test probe group numbers as the test probe group number group information;

[0012] When the weight information gradually reaches the full load weight information, the test probe group corresponding to the test probe group number group information is abutted against the raceway surface, and after the inner ring of the bearing is rotated around the central axis, the extension length information detected on the test probe group of the test probe group number group information is obtained;

[0013] Judging in turn whether the extension length information always falls within a preset allowable range;

[0014] If it falls within, the uppermost inner ring of the bearing is successively pushed onto the conveyor belt and run to the next working condition until a feeding signal is triggered;

[0015] If it does not fall within, obtain the test probe group number in the test probe group number group information that does not fall within, and define this test probe group number as abnormal test probe group number information;

[0016] Perform matching analysis based on the test probe group number queue information stored in the preset feeding database and the abnormal test probe group number information to determine the test probe group number queue corresponding to the abnormal test probe group number information, and define this test probe group number queue as abnormal test probe group number queue information;

[0017] After taking out the inner ring of the bearing corresponding to the abnormal test probe group number information and above in the abnormal test probe group number queue information, replace it with the lowermost inner ring of the bearing, and then put it back into the corresponding position and continue to obtain the extension length information until all the extension length information falls within the allowable range, and then push the uppermost inner ring of the bearing onto the conveyor belt and run to the next working condition.

[0018] By adopting the above technical solutions, when feeding is required, the weight borne above is calculated to determine the inner ring of the bearing that needs to be added, and then a test probe group is set at each added inner ring of the bearing for telescopic testing to measure the depth, size and flatness of the raceway surface. Those that do not meet the standards are automatically removed, so as to realize the process of automatic material inspection during the feeding process, without manual detection, with high detection efficiency and improved feeding efficiency.

[0019] Optionally, the method for determining the test probe group number group information according to the required weight information includes:

[0020] Obtain the thrust information on both sides of the push plate that pushes the inner ring of the bearing upward;

[0021] Calculate the thrust deviation information according to the thrust information;

[0022] Calculate the unit bearing inner ring weight information respectively with two different preset queue distance information to obtain two unit torque information. Define the unit torque information far from the middle side of the push plate as the edge unit torque information, and define the unit torque information close to the middle side of the push plate as the middle unit torque information;

[0023] Calculate the equivalent unit gravity information on the side and in the middle by respectively calculating the information of the moment of the unit on the side and the information of the moment of the unit in the middle with the preset thrust arm information of the push plate;

[0024] Distribute the thrust deviation information according to the equivalent unit gravity information on the side and the equivalent unit gravity information in the middle to obtain different combinations of the equivalent unit gravity information on the side and the equivalent unit gravity information in the middle, and define this combination as the equivalent combination information;

[0025] Arbitrarily select an equivalent combination information to increase or decrease the inner ring of the bearing, and define the selected equivalent combination information as the current equivalent combination information;

[0026] Obtain the intermediate thrust information and calculate the deviation between the intermediate thrust information and the thrust information, and define this deviation as the test thrust deviation information;

[0027] Judge whether the test thrust deviation information is equal to 0;

[0028] If so, increase or decrease the inner ring of the bearing according to the current equivalent combination information and re-obtain the required weight information and the abnormal test needle group number information;

[0029] If not, select another equivalent combination information and continue to obtain the test thrust deviation information.

[0030] By adopting the above technical solution, it is judged whether the inner rings of the bearings above are evenly arranged through the thrust deviation values on both sides, and then the combination of the differences in the number between the two stacks of the inner rings of the bearings at two relative positions is determined through the theorem of moment balance, and then it is determined whether the equivalent combination information is correct by whether the intermediate thrust information is the same as other thrust information, so as to place the inner rings of the bearings on the corresponding queues specifically, making the topmost finally flush, so that the quantity pushed onto the conveyor belt each time is the maximum, improving the feeding efficiency of the feeding device.

[0031] Optionally, the method of replacing the lowermost inner ring of the bearing after taking out the inner rings of the bearings corresponding to the abnormal test needle group number information and above in the abnormal test needle group number queue information includes:

[0032] Calculate the corresponding number difference according to the maximum test needle group number information and the abnormal test needle group number information corresponding to the abnormal test needle group number queue information, and define this difference as the number difference information;

[0033] Obtain the information of the number of times the inner ring of the bearing has been pushed forward from the bearing column onto the conveyor belt;

[0034] Judge whether the information of the number of times pushed is equal to the number difference information;

[0035] If it is equal, push it in the reverse direction to remove the inner ring of the bearing at the top of the abnormal test probe group number queue information corresponding to the abnormal test probe group number information;

[0036] If it is not equal, continue to push it forward onto the conveyor belt.

[0037] By adopting the above technical solution, by normally pushing out all the normal inner rings of the bearing above the inner ring of the bearing corresponding to the abnormal test probe group number information onto the conveyor belt, it is ensured that the normal operation of the feeding device is not affected during the process of removing the abnormal inner ring of the bearing, thus improving the feeding fluency of the feeding device.

[0038] Optionally, the method of pushing it in the reverse direction to remove the inner ring of the bearing at the top of the abnormal test probe group number queue information corresponding to the abnormal test probe group number information includes:

[0039] Perform matching analysis based on the adjacent area information stored in the preset adjacent database and the abnormal test probe group number queue information to determine the area adjacent to the push plate area where the inner ring of the bearing is pushed out corresponding to the abnormal test probe group number queue information, and define this area as the abnormal adjacent area information;

[0040] Perform matching analysis based on the electromagnet number information stored in the preset magnetic attraction database and the abnormal adjacent area information to determine the electromagnet number corresponding to the abnormal adjacent area information, and define this magnet number as the normal electromagnet number information;

[0041] Obtain the push distance information of the push plate;

[0042] When pushing in the reverse direction and the push distance information is equal to the preset abutting distance information, energize the normal electromagnet number information;

[0043] When pushing in the reverse direction and the push distance information is equal to the preset critical tipping distance information, stop pushing and move forward to the abutting distance information and then de-energize the normal electromagnet number information.

[0044] By adopting the above technical solution, during the process of pushing out the abnormal inner ring of the bearing, the normal inner rings of the other positions are adsorbed, so that the normal inner rings of the bearing are not easily dropped and can return above the inner ring column of the bearing, and then are pushed onto the conveyor belt, so that only the abnormal inner ring of the bearing is pushed out and the situation of repeated feeding of the normal inner rings of the bearing is not easily caused, thus improving the feeding efficiency of the normal inner rings of the bearing.

[0045] Optionally, the method of de-energizing the normal electromagnet number information when moving forward to the abutting distance information includes:

[0046] Obtain the lower test probe group number information one below the abnormal test probe group number information on the same abnormal test probe group number queue information;

[0047] Perform matching analysis based on the adjacent test probe group number information and the lower test probe group number information stored in the preset number database to determine the adjacent test probe group number corresponding to the lower test probe group number information, and define this area as the lower adjacent test probe group number information;

[0048] Determine whether there is abnormal test probe group number information in the lower adjacent test probe group number information and the lower test probe group number information;

[0049] If there is, when moving forward to the abutting distance information, cut off the power supply of the normal electromagnet number information;

[0050] If not, calculate the difference between the abutting distance information and the critical tipping distance information, and define this difference as the moving distance information;

[0051] Calculate the difference between the moving distance information and the preset sliding distance information, and define this difference as the disconnection distance information;

[0052] During forward movement, raise the inner ring of the bearing corresponding to the lower adjacent test probe group number information and the lower test probe group number information to be flush with the abnormal test probe group number information, and then continue to move forward to the disconnection distance information to cut off the power supply of the normal electromagnet number information until the inner ring of the bearing corresponding to the lower adjacent test probe group number information and the lower test probe group number information is pushed onto the conveyor belt.

[0053] By adopting the above technical solution, when the next group are all normal inner rings of the bearing, when the push plate rebounds to the position of the inner ring column of the bearing, the next group of inner rings of the bearing can be all pushed onto the conveyor belt, so that during the time when the normal inner rings of the bearing in the same row as the abnormal inner ring of the bearing need to be put back onto the inner ring column of the bearing and then the inner ring column of the bearing is moved down and these several returned inner rings of the bearing are discharged, the normal inner ring column of the bearing can still be pushed out, improving the feeding fluency of the feeding device.

[0054] Optionally, if there is abnormal test probe group number information in the lower adjacent test probe group number information and the lower test probe group number information, the method of cutting off the power supply of the normal electromagnet number information when moving forward to the abutting distance information:

[0055] Define the queue of the abnormal test probe group number information existing below as the lower abnormal test probe group number queue information;

[0056] Perform matching analysis based on the relative area information stored in the preset area database and the lower abnormal test probe group number queue information to determine the relative area for pushing out the inner ring of the bearing corresponding to the lower abnormal test probe group number queue information, and define this area as the lower abnormal relative area information;

[0057] Match and analyze according to the electromagnet number information stored in the magnetic attraction database and the abnormal relative area information below to determine the electromagnet number corresponding to the abnormal relative area information below, and define this magnet number as the abnormal electromagnet number information;

[0058] When moving forward, raise the bearing inner rings corresponding to the lower adjacent test probe group number information and the lower test probe group number information to the same level as the abnormal test probe group number information, and then continue to move forward to the disconnection distance information, cut off the power supply of the normal electromagnet number information and energize the pair of abnormal electromagnet number information until the bearing inner rings corresponding to the lower adjacent test probe group number information and the lower test probe group number information are pushed onto the conveyor belt.

[0059] By adopting the above technical solution, when a group of the lower bearings are not all normal inner rings, the abnormal bearing inner rings are attracted by reversing the electromagnet and the remaining bearing inner rings enter the conveyor belt, so that although there are abnormal bearing inner rings, the normal bearing inner rings in the same row can still be pushed out, further improving the feeding fluency of the feeding device.

[0060] Optionally, the method for checking the abnormal test probe group number information includes:

[0061] Obtain the abnormal extension length information that does not fall within the allowable range;

[0062] Continue to obtain the extension length information after the preset cleaning time information, and define this extension length information as the interval extension length information;

[0063] Judge whether the interval extension length information still does not fall within the allowable range;

[0064] If it falls within, do not output the abnormal test probe group number information;

[0065] If it does not fall within, when the number of pushed times information is increased by one, obtain the upper test probe group number information above the abnormal test probe group number information on the same abnormal test probe group number queue information;

[0066] Obtain the extension length information when testing the upper test probe group number information, and define this extension length information as the upper abnormal extension length information;

[0067] Judge whether the upper abnormal extension length information falls within the allowable range;

[0068] If it falls within, output the abnormal test probe group number information and output the test probe group self-abnormal information;

[0069] If it does not fall within, output the abnormal test probe group number information and output the bearing inner ring abnormal information.

[0070] By adopting the above technical solution, the inner ring of the bearing is raised by the height of one inner ring of the bearing, and then tested. Through two tests, the reason for the abnormal extended length information is determined, and then the reason is output. If the reason is the abnormality of the test needle group itself, the staff needs to perform maintenance. If the reason is the inner ring of the bearing, the abnormal inner ring of the bearing is removed, thereby improving the accuracy of detection by the feeding device.

[0071] In a second aspect, the present application provides a feeding system for the inner ring of a bearing, adopting the following technical solution:

[0072] A feeding system for the inner ring of a bearing, comprising:

[0073] An acquisition module, configured to acquire weight information, feeding signal, current weight information, extended length information, abnormal extended length information, interval extended length information, upper abnormal extended length information, abnormal test needle group number information, lower test needle group number information, thrust information, number of times pushed information, and pushing distance information;

[0075] A processor, the program in the memory can be loaded and executed by the processor and implement the control method of any of the above-mentioned bearing inner ring feeding methods.

[0076] By adopting the above technical solution, when feeding is required, the bearing inner rings to be added are determined by calculating the weight borne above, and then a test needle group is set at each added bearing inner ring for telescopic testing to measure the depth, size, and flatness of the raceway surface. Those that do not meet the standards are automatically removed, thereby realizing the process of automatic material inspection during the feeding process, without the need for manual inspection, with high detection efficiency and improved feeding efficiency.

[0077] In a third aspect, the present application provides an intelligent terminal, adopting the following technical solution:

[0078] An intelligent terminal, comprising a memory and a processor, and a computer program capable of being loaded and executed by the processor is stored on the memory for any of the above-mentioned motor winding methods.

[0083] By adopting the above technical solution, when feeding is required, the weight borne above is calculated to determine the inner ring of the bearing that needs to be added, and then a test needle group is set at each added inner ring of the bearing for telescopic testing to measure the depth, size, and flatness of the raceway surface. Those that do not meet the standards are automatically removed, thereby realizing the process of automatically inspecting materials during the feeding process, eliminating the need for manual inspection, with high detection efficiency and improved feeding efficiency.

[0097] In order to make the objectives, technical solutions and advantages of the present application clearer, the following Figures 1-9 in conjunction with the accompanying drawings and embodiments, the present application will be further described in detail. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0098] The embodiment of the present application discloses a method for loading inner bearing rings. Referring to Figure 1 , the method for loading inner bearing rings includes:

[0099] Step 100: Obtain the weight information and a preset feeding signal, and define the weight information before obtaining the feeding signal as the current weight information.

[0100] The weight information is the information of the weight of the inner bearing ring to be loaded. For example Figure 2As shown in the figure, an ascending push plate that can move up and down is installed on the feeding device, and a motor screw structure passing through the ascending push rod is installed below. The bearing inner ring columns are placed above the ascending push plate. The screw passes through the bearing inner ring columns and has a driving force with the bearing inner ring columns. In order to ensure that the bearing inner ring does not easily rub when rotating with the screw, anti-friction stickers can be set on the bearing inner ring. The way to obtain the weight is to set a push rod below, and then subtract the known weights of other objects from the sum of the thrust information obtained on the push rod. The feeding signal is a signal that requires the system to add raw materials. It is a judgment signal, that is, when a certain condition is met, this signal will be automatically triggered to execute a certain command. The conditions here are, for example: when the weight is lower than a certain fixed value, this signal is triggered, or it can also be the state when the ascending push plate rises to a certain height.

[0101] Step 101: When the feeding signal is obtained, calculate the required weight information based on the current weight information and the preset full-load weight information.

[0102] The full-load weight information is the information of the maximum weight when the bearing inner ring columns are stacked to the highest degree. The required weight information is the information of the weight value required to reach the full-load weight information from the current weight information. The calculation method is the full-load weight information minus the current weight information.

[0103] Step 102: Calculate the bearing inner ring quantity information based on the required weight information and the preset unit bearing inner ring weight information.

[0104] The unit bearing inner ring weight information is the information of the standard weight of a single bearing inner ring, which is measured by the staff in advance. The bearing inner ring quantity information is the information of the number of bearing inner rings that need to be added. The calculation method is the required weight information divided by the unit bearing inner ring weight information.

[0105] Step 103: Perform matching analysis based on the test needle group number information stored in the preset test needle group database and the bearing inner ring quantity information to determine the set of test needle group numbers corresponding to the bearing inner ring quantity information, and define this set of test needle group numbers as the test needle group number set information.

[0106] The test needle group number set information is the information of the set formed by the numbers of the test needle groups. Such as Figure 2As shown, at each position, needles for testing the inner ring size of the bearing are laid flat to form a group. When the bearing inner rings are placed in sequence from bottom to top and are below the baffle plate, the needles of the test needle group just all abut against the outer ring of the bearing inner ring and are arranged along the vertical direction. Some abut against the upper and lower annular surfaces, and some abut against the raceway surface. The mapping relationship between the test needle group number information and the bearing inner ring quantity information is stored in the database and numbered from top to bottom by the staff in this field. Since the bearing inner rings on the feeding device are pushed upward by the same push plate, all the bearing inner rings are evenly arranged, and the number of bearing inner rings is a multiple of the number of bearing inner ring columns. Therefore, when the quantity is different, it can be known the area covered by the newly added bearing inner rings, and thus compared with the test needle group number to form. When the system receives the bearing inner ring quantity information, it automatically searches the corresponding test needle group number from the database and outputs the set with the test needle group number group information.

[0107] Step 104: When the weight information gradually reaches the full-load weight information, abut the test needle group corresponding to the test needle group number group information against the raceway surface, rotate the bearing inner ring around the central axis, and obtain the extension length information detected on the test needle group of the test needle group number group information.

[0108] The extension length information is the information of the length that the test needle group extends out of the test needle group outlet. Substantially, it is a curve graph of the extension length, which truly reflects the circumferential profile of the outer periphery of the bearing inner ring. When the weight information gradually reaches the full-load weight information, at this time, all the newly added bearing inner rings have been stacked. Then, the corresponding test needles for each newly added bearing inner ring position are abutted against the raceway surface. The purpose of abutting is to measure whether the size meets the requirements, and the purpose of rotating one circle is to measure whether all the surfaces are consistent. Rotating one circle can be obtained by rotating with the motor lead screw below.

[0109] Step 105: Sequentially judge whether the extension length information always falls within the preset allowable range.

[0110] The allowable range is the information of the range with deviation from the allowable size set by the user. The judgment method is numerical comparison.

[0111] Step 1051: If it falls within, sequentially push the uppermost bearing inner ring onto the conveyor belt and run it to the next working condition until the feeding signal is triggered.

[0112] If it falls within, it means that all the bearing inner rings meet the requirements, and then the feeding can be directly started. The rising push plate rises through the push rod, the uppermost bearing inner ring moves above the baffle plate, and then the bearing inner ring above the baffle plate is pushed onto the conveyor belt by the transverse push plate.

[0113] Step 1052: If it does not fall within, obtain the test needle group number in the test needle group number group information that does not fall within, and define this test needle group number as the abnormal test needle group number information.

[0114] The abnormal test needle group number information is the information of the test needle group number for which the measured inner ring of the bearing does not meet the requirements. If it does not fall within, it means that the test needle group number information measures that the inner ring of the bearing does not meet the requirements, and thus it needs to be excluded.

[0115] Step 106: Perform matching analysis based on the test needle group number queue information and the abnormal test needle group number information stored in the preset feeding database to determine the test needle group number queue corresponding to the abnormal test needle group number information, and define this test needle group number queue as the abnormal test needle group number queue information.

[0116] The abnormal test needle group number queue information is the information of the queue in the vertical direction where the abnormal test needle group number information is located. Here, the abnormal test needle group number information is the lowest test needle group number in the queue. There is a mapping relationship between the test needle group number queue information and the abnormal test needle group number information stored in the database, which is obtained by the staff in this field according to the actual number arrangement, and then observing and recording after taking any one number as the abnormal test needle group number information. When the system receives the abnormal test needle group number information, it automatically searches the database for the test needle group number queue and outputs it as the abnormal test needle group number queue information.

[0117] Step 107: After taking out the corresponding inner ring of the bearing from the abnormal test needle group number queue information from the abnormal test needle group number information and above, replace the lowest inner ring of the bearing, and then put it back into the corresponding position and continue to obtain the extension length information until all the extension length information falls within the allowable range, and then push the uppermost inner ring of the bearing onto the conveyor belt to run to the next working condition.

[0118] When detecting the abnormal test needle group number information, take out the bearing columns corresponding to the test needle group number information of the entire queue to take out and replace the inner ring of the bearing, realizing the process of automatic material inspection and material replacement during the feeding process, without manual detection, with high detection efficiency and improved feeding efficiency.

[0119] Refer to Figure 3 , the method for determining the test needle group number group information according to the required weight information includes:

[0120] Step 200: Obtain the thrust information on both sides of the push plate that pushes the inner ring of the bearing upward.

[0121] The thrust information is the information of the thrust that supports the rising push plate and can rise at a constant speed. Lifting push rods are installed on both sides of the rising push plate. Figure 2Not shown in the figure, then install a gravity detection device at the corresponding position for detection, and zero it after removing the inner ring of the bearing, so that the gravity detection device can only detect the information of the weight of the inner ring of the bearing.

[0122] Step 201: Calculate the thrust deviation information based on the thrust information.

[0123] The thrust deviation information is the information of the deviation of the thrust on both sides. It can be obtained by subtracting the data of one side from the data of the other side, and the positive and negative only represent the direction.

[0124] Step 202: Calculate the unit bearing inner ring weight information respectively with two different preset queue center distances to obtain two unit torque information. Define the unit torque information far from the middle side of the push plate as the edge unit torque information, and the unit torque information close to the middle side of the push plate as the middle unit torque information.

[0125] The queue center distance information is the distance information of the inner ring column of the bearing from the middle side of the rising push plate, which is measured by the staff according to the actual situation. Two are set here, and when the number of inner ring columns of the bearing is greater than four, other numbers can also be set. It should be noted that there is no multiple relationship between the two here, so that the distinction between the two is relatively large. The edge unit torque information is the information of the torque when a single inner ring of the bearing on the two inner ring columns of the bearing closer to the edge of the rising push plate on the same side is centered. The middle unit torque information is the information of the torque when a single inner ring of the bearing on the two inner ring columns of the bearing closer to the middle side of the rising push plate on the same side is centered. The calculation method is the product of the two.

[0126] Step 203: Calculate the edge equivalent unit gravity information and the middle equivalent unit gravity information respectively according to the edge unit torque information and the middle unit torque information and the preset thrust force arm information of the push plate.

[0127] The thrust force arm information is the information of the force arm of the pushing point of the lifting push rod from the middle side of the push plate. The edge equivalent unit gravity information is the information of the equivalent gravity when the inner ring of the bearing corresponding to the edge unit torque information is equivalent to the position corresponding to the thrust force arm information. The middle equivalent unit gravity information is the information of the equivalent gravity when the inner ring of the bearing corresponding to the middle unit torque information is equivalent to the position corresponding to the thrust force arm information. The calculation method is the quotient of the edge unit torque information and the middle unit torque information divided by the thrust force arm information respectively.

[0128] Step 204: Distribute the thrust deviation information according to the edge equivalent unit gravity information and the middle equivalent unit gravity information to obtain different combinations of the edge equivalent unit gravity information and the middle equivalent unit gravity information, and define this combination as the equivalent combination information.

[0129] The equivalent combination information is the information of a combination formed by a number of edge equivalent unit gravity information and middle equivalent unit gravity information. The condition it satisfies is that the sum of the two is equal to the thrust deviation information. Since the measured thrust deviation information is only caused by the difference in the number between the columns of the inner ring of the bearing, it can be known that it must be the result of different combinations. And the two at the symmetric positions on the middle side of the push plate can be equivalent to each other through addition and subtraction. Therefore, two settings on one side can be set to 0, and then different combinations on the other side form the thrust deviation information for equivalent replacement. Since the queue distance information from the middle set previously is not a multiple of each other, the combination situation between the two is less, so it is easy to obtain a smaller number of equivalent combination information, and there may even be only one equivalent combination information. Its ultimate goal is to make the inner rings of the bearings on both sides of the rising push plate symmetric.

[0130] Step 205: Arbitrarily select an equivalent combination information to increase or decrease the inner ring of the bearing, and define the selected equivalent combination information as the current equivalent combination information.

[0131] The current equivalent combination information is the currently selected equivalent combination information. Only place the number of combinations corresponding to one of the equivalent unit gravity information in the current equivalent combination information, and then observe whether the remaining ones meet the requirements to know whether the actual current equivalent combination information meets the requirements, without having to detect after placing both according to the combination, which improves the detection efficiency.

[0132] Step 206: Obtain the middle thrust information and calculate the deviation between the middle thrust information and the thrust information, and define this deviation as the test thrust deviation information.

[0133] The middle thrust information is the information of the thrust of the electric push rod in the middle of the rising push plate, and the acquisition method is the same as that of the thrust information. The test thrust deviation information is the information of the deviation between the thrusts on both sides and the middle thrust measured after increasing or decreasing the inner ring of the bearing according to the equivalent combination information. The purpose of the calculation is to determine whether both sides are flush if combined according to the current equivalent combination information.

[0134] Step 207: Judge whether the test thrust deviation information is equal to 0.

[0135] Step 2071: If so, increase or decrease the inner ring of the bearing according to the current equivalent combination information and re-obtain the required weight information and the abnormal test needle group number information.

[0136] If so, it indicates that the thrust on both sides is equal to the thrust in the middle, which means that the current equivalent combination information can make the columns of the inner ring of the bearing flush. Therefore, the inner ring of the bearing can be increased or decreased according to the current equivalent combination information, and then continue to perform self-checking according to steps 100-107. It should be noted that the inner ring of the bearing added according to the current equivalent combination information also needs to be measured.

[0137] Step 2072: If not, then select other equivalent combination information and continue to obtain the test thrust deviation information.

[0138] If not, it means that the currently selected equivalent combination information does not meet the requirements. Then select other equivalent combination information and continue to obtain the test thrust deviation information.

[0139] Refer to Figure 4 , the method of replacing the lowermost inner ring of the bearing after taking out the inner rings of the bearings corresponding to the abnormal test needle group number information and above in the abnormal test needle group number queue information includes:

[0140] Step 300: Calculate the corresponding number difference according to the maximum test needle group number information and the abnormal test needle group number information corresponding to the abnormal test needle group number queue information, and define this difference as the number difference information.

[0141] The maximum test needle group number information is the information of the largest test needle group number in the same queue corresponding to the abnormal test needle group number queue information. In the embodiments of the present application, the numbers are from bottom to top, and the uppermost one is the largest number value in the same queue. The maximum test needle group number information is only used to determine the position of the uppermost inner ring of the bearing and determine the maximum number in a queue, and does not have other meanings. The number difference information is the numerical difference between the number corresponding to the abnormal test needle group number information and the number corresponding to the tube of the maximum test needle group number information. The calculation method is the maximum test needle group number information minus the abnormal test needle group number information.

[0142] Step 301: Obtain the information of the number of times the inner ring of the bearing has been pushed forward from the bearing column to the conveyor belt in the positive direction.

[0143] The information of the number of times pushed is the information of the number of times counted from the maximum test needle group number information in the same queue until now. The obtaining method can be any kind of counter method, that is, when pushed once, a count is made once.

[0144] Step 302: Determine whether the information of the number of times pushed is equal to the number difference information.

[0145] The purpose of the determination is to determine whether the next push is the row where the inner ring of the bearing corresponding to the abnormal test needle group number information is located.

[0146] Step 3021: If it is equal, push backward to remove the inner ring of the bearing at the top of the abnormal test probe group number queue information corresponding to the abnormal test probe group number information.

[0147] If it is equal, it can be pushed backward so that the inner ring of the bearing at the top of the abnormal test probe group number queue information corresponding to the abnormal test probe group number information does not enter the conveyor belt. The method here is to first push the horizontal push plate to the side close to the conveyor belt, then raise a row of the abnormal test probe group number information above the baffle, and then move the push plate to the side away from the conveyor belt to push the inner ring of the bearing at the top to the side away from the conveyor belt.

[0148] Step 3022: If it is not equal, continue to push forward to the conveyor belt.

[0149] If it is not equal, it means that the next row is not the row where the abnormal test probe group number information is located, so it can be normally pushed out.

[0150] Refer to Figure 5 , the method of pushing backward to remove the inner ring of the bearing at the top of the abnormal test probe group number queue information corresponding to the abnormal test probe group number information includes:

[0151] Step 400: Perform matching analysis based on the adjacent area information stored in the preset adjacent database and the abnormal test probe group number queue information to determine the area adjacent to the push plate area for pushing out the inner ring of the bearing corresponding to the abnormal test probe group number queue information, and define this area as the abnormal adjacent area information.

[0152] The abnormal adjacent area information is the area adjacent to the area corresponding to the abnormal test probe group number queue information on the rising push plate. For example Figure 2 when the local queue in the third queue from left to right is the abnormal test probe group number queue information, the areas where the other first queue, second queue, and fourth queue contact the horizontal push plate are the abnormal adjacent area information. The mapping relationship between the adjacent area information and the abnormal test probe group number queue information is stored in the database. It is obtained by the observation of the staff in this field. When the system receives the abnormal test probe group number queue information, it automatically searches the database for the area adjacent to the push plate area for pushing out the inner ring of the bearing, and then outputs it as the abnormal adjacent area information.

[0153] Step 401: Perform matching analysis based on the electromagnet number information stored in the preset magnetic attraction database and the abnormal adjacent area information to determine the electromagnet number corresponding to the abnormal adjacent area information, and define this magnet number as the normal electromagnet number information.

[0154] The normal electromagnet number information is the electromagnet number information within the area on the transverse push plate corresponding to the abnormal adjacent area information. The mapping relationship between the electromagnet number information and the abnormal adjacent area information is stored in the database, which is obtained by the staff in this field one by one after installing the electromagnets.

[0155] Step 402: Obtain the pushing distance information of the push plate.

[0156] The pushing distance information is the information of the position where the push plate is located during the transverse pushing process. The obtaining method can be the infrared detection method.

[0157] Step 403: Energize the normal electromagnet number information when pushing in the reverse direction and the pushing distance information is equal to the preset abutting distance information.

[0158] The abutting distance information is the information of the position when the transverse push plate just abuts against the outer circumferential side wall of the inner ring of the bearing close to the conveyor belt. When pushing in the reverse direction and the abutting distance information is reached, energize the normal electromagnet number information. At this time, except for the inner ring of the bearing corresponding to the abnormal test needle group number information, there is a certain adsorption force between the other inner rings of the bearings and the push plate.

[0159] Step 404: Stop pushing when pushing in the reverse direction and the pushing distance information is equal to the preset critical tipping distance information, and then move forward to the abutting distance information and cut off the power of the normal electromagnet number information.

[0160] The critical tipping distance information is the information of the position where the inner ring of the bearing just drops on the baffle when the push plate pushes the inner ring of the bearing to this position. At this time, since there is a certain adsorption force between the inner rings of the bearings except for the inner ring of the bearing corresponding to the abnormal test needle group number information and the push plate, these inner rings of the bearings are not easy to drop, while the inner ring of the bearing corresponding to the abnormal test needle group number information drops due to the lack of adsorption force. Then, when moving forward to the abutting distance information, cut off the power of the normal electromagnet number information. At this time, the inner rings of the bearings that have not dropped return to the bearing column. Then, lower the rising push plate. After the transverse push plate moves to the end far from the conveyor belt, raise the rising push plate again so that the inner rings of the bearings that have not dropped are located on the side of the transverse push plate close to the conveyor belt and are pushed onto the conveyor belt.

[0161] Refer to Figure 6 , the method of cutting off the power of the normal electromagnet number information when moving forward to the abutting distance information includes:

[0162] Step 500: Obtain the lower test needle group number information that is one below the abnormal test needle group number information on the same abnormal test needle group number queue information.

[0163] The information of the lower test needle group number is the information of the test needle group number that is one below the abnormal test needle group number information in the same abnormal test needle group number queue information. The acquisition method is to subtract one from the numerical value of the number.

[0164] Step 501: Perform a matching analysis based on the adjacent test needle group number information and the lower test needle group number information stored in the preset number database to determine the adjacent test needle group number corresponding to the lower test needle group number information, and define this area as the lower adjacent test needle group number information.

[0165] The lower adjacent test needle group number information is the information of the test needle group numbers on other queues in the same row as the lower test needle group number information. The mapping relationship between the adjacent test needle group number information and the lower test needle group number information is stored in the database and obtained by the staff in this field through actual observation.

[0166] Step 502: Determine whether there is abnormal test needle group number information in the lower adjacent test needle group number information and the lower test needle group number information.

[0167] The purpose of the determination is to determine whether the inner ring of the bearing in the next row meets the requirements.

[0168] Step 5021: If there is, when moving forward to the abutting distance information, cut off the power supply of the normal electromagnet number information.

[0169] If there is, it means that the inner ring of the bearing in the next row does not meet the requirements at this time, so it still needs to be discharged. Therefore, only when moving to the abutting distance information, cut off the power supply of the normal electromagnet number information, then lower the rising push plate. After the transverse push plate moves to one end away from the conveyor belt, raise the rising push plate again so that the inner ring of the bearing that has not fallen is located on the side of the transverse push plate close to the conveyor belt and is pushed onto the conveyor belt.

[0170] Step 5022: If not, calculate the difference between the abutting distance information and the critical tipping distance information, and define this difference as the moving distance information.

[0171] The moving distance information is the information of the distance value from the position corresponding to the critical tipping distance information to the position corresponding to the abutting distance information. The calculation method is to subtract the two and then take the absolute value. If not, it means that the inner rings of the bearings in the next row all meet the requirements.

[0172] Step 503: Calculate the difference between the moving distance information and the preset sliding distance information, and define this difference as the disconnection distance information.

[0173] The sliding distance information is the information of the distance that the inner ring of the bearing can move after suddenly disconnecting the pulling of the transverse push plate when it moves on the baffle plate at the pulling speed caused by the magnetic attraction of the transverse push plate. Here, it is defined that the moving process of the cylinder is uniform, that is, the acceleration and deceleration processes at both ends are in a very short time and distance, and then it is pushed in a uniform moving manner in the middle. The disconnection distance information is the information of the position where the inner ring of the bearing can move to the column of the inner ring of the bearing after disconnecting from this position. The calculation method is the moving distance information minus the sliding distance information.

[0174] Step 504: When moving forward, raise the bearing inner ring corresponding to the lower adjacent test needle group number information and the lower test needle group number information to the same level as the abnormal test needle group number information, and then continue to move forward to the disconnection distance information and cut off the power supply of the normal electromagnet number information until the bearing inner ring corresponding to the lower adjacent test needle group number information and the lower test needle group number information is pushed onto the conveyor belt.

[0175] When moving forward, raise the bearing inner ring corresponding to the lower adjacent test needle group number information and the lower test needle group number information to the same level as the abnormal test needle group number information. At this time, the push plate still adsorbs the bearing inner ring of the previous row. Therefore, in order to move the bearing inner ring of the previous row to the side of the transverse push plate close to the conveyor belt, it is placed on the column of the inner ring of the bearing to facilitate up and down movement. The purpose of cutting off the power supply when moving forward to the disconnection distance information is to prevent the bearing inner ring of the previous row from easily crossing the column of the inner ring of the bearing and reaching the other side when advancing by suction.

[0176] Refer to Figure 7 , if there is abnormal test needle group number information in the lower adjacent test needle group number information and the lower test needle group number information, the method of cutting off the power supply of the normal electromagnet number information when moving forward to the abutting distance information:

[0177] Step 600: Define the queue of the abnormal test needle group number information existing below as the lower abnormal test needle group number queue information.

[0178] The lower abnormal test needle group number queue information is the information of the queue where the test needle group numbers corresponding to the bearing inner rings that are still abnormal in the bearing inner rings of the next row are located. The definition method is the same as that in Step 106.

[0179] Step 601: Perform matching analysis based on the relative area information stored in the preset area database and the lower abnormal test needle group number queue information to determine the relative area for pushing out the bearing inner ring corresponding to the lower abnormal test needle group number queue information, and define this area as the lower abnormal relative area information.

[0180] The following abnormal relative area information is the information of the area where the inner ring of the bearing and the rising push plate are in contact corresponding to the abnormal test probe group number queue information. The mapping relationship between the relative area information and the following abnormal test probe group number queue information is stored in the database and obtained by the staff in the field according to the actual situation. When the system receives the corresponding following abnormal test probe group number queue information, it automatically searches the database for the corresponding relative area and outputs it as the following abnormal relative area information.

[0181] Step 602: Perform matching analysis based on the electromagnet number information stored in the magnetic attraction database and the following abnormal relative area information to determine the electromagnet number corresponding to the following abnormal relative area information, and define this magnet number as the abnormal electromagnet number information.

[0182] The abnormal electromagnet number information is the information of the number of the electromagnet existing at the location of the following abnormal relative area information. When the system receives the abnormal relative area information, it automatically searches the database for the corresponding electromagnet number and outputs it as the abnormal electromagnet number information.

[0183] Step 603: When moving forward, raise the inner ring of the bearing corresponding to the following adjacent test probe group number information and the following test probe group number information to the same level as the abnormal test probe group number information, and then continue to move forward to the disconnection distance information, cut off the power supply of the normal electromagnet number information and energize the abnormal electromagnet number information pair until the inner ring of the bearing corresponding to the following adjacent test probe group number information and the following test probe group number information is pushed onto the conveyor belt.

[0184] The purpose of energizing the abnormal electromagnet number information pair is to adsorb the inner ring of the bearing corresponding to the abnormal test probe group number information in the next row so that it does not fall onto the conveyor belt. The remaining normal inner rings of the bearings can enter the conveyor belt and then be pushed backward again. At this time, the inner ring column of the bearing moves downward, and the inner ring of the bearing corresponding to the abnormal test probe group number information in the next row returns to the inner ring column of the bearing and falls parallel to the normal inner rings of the bearings in the previous row, and then continue to operate according to steps 500 - 504. When there is also an inner ring of the bearing corresponding to the abnormal test probe group number information in the next row, operate according to steps 600 - 603.

[0185] Refer to Figure 8 , the verification method of the abnormal test probe group number information includes:

[0186] Step 700: Obtain the abnormal extension length information that does not fall within the allowable range.

[0187] The abnormal protrusion length information is the information of the protrusion length that does not meet the requirements of the inner ring size information of the bearing. The acquisition method is by comparison, that is, when its value does not fall within the allowable range, it is defined as the abnormal protrusion length information.

[0188] Step 701: Continue to acquire the protrusion length information after the preset cleaning time information, and define this protrusion length information as the intermittent protrusion length information.

[0189] The cleaning time information is the information that can remove the impurities on the raceway surface of the inner ring of the bearing after multiple cleanings. Here, it is defaulted to a certain time point, that is, the part that has not been removed even after exceeding this time point is the impurity that is difficult to remove, and it can be defaulted to a part on the inner ring of the bearing rather than an impurity. The intermittent protrusion length information is the protrusion length information after the cleaning time information. Here, after the cleaning time information, the test needle group continuously contacts the inner ring of the bearing and cleans some parts that can be cleaned, so as to avoid the interference of the impurities remaining on the raceway surface on the judgment.

[0190] Step 702: Determine whether the intermittent protrusion length information still does not fall within the allowable range.

[0191] The purpose of the determination is to determine whether it is an impurity.

[0192] Step 7021: If it falls within, do not output the abnormal test needle group number information.

[0193] If it falls within, it means that although it did not fall within before due to the presence of impurities, the impurities have been cleaned after the cleaning time, and now it falls within the allowable range, which means that the inner ring of the bearing actually meets the size requirements, so the abnormal test needle group number information can be not output.

[0194] Step 7022: If it does not fall within, when the number of pushing times information is increased by one, acquire the upper test needle group number information above the abnormal test needle group number information on the same abnormal test needle group number queue information.

[0195] The upper test needle group number information is the information of the upper test needle group number above the abnormal test needle group number on the same abnormal test needle group number queue information. The acquisition method is to increase by one numerically. If it does not fall within, it means that it still does not meet the requirements after cleaning, which means there is an abnormal situation. In order to determine whether the abnormality occurs on the test needle or on the inner ring of the bearing, a judgment needs to be made.

[0196] Step 703: Acquire the protrusion length information when testing with the upper test needle group number information, and define this protrusion length information as the upper abnormal protrusion length information.

[0197] The upper abnormal extension length information is the information of the extension length measured when the bearing inner ring corresponding to the abnormal test probe group number information is detected by the upper test probe group number information. Since the number of times of pushing has increased by one, the bearing inner ring corresponding to the abnormal test probe group number information has risen to the position of the upper test probe group number information.

[0198] Step 704: Determine whether the upper abnormal extension length information falls within the allowable range.

[0199] The purpose of the determination is to determine whether the abnormal situation occurs on the test probe or on the bearing inner ring.

[0200] Step 7041: If it falls within, output the abnormal test probe group number information and output the self-abnormal information of the test probe group.

[0201] The self-abnormal information of the test probe group is the information of the abnormal situation on the test probe group itself. The output method is in the form of text display. If it falls within, it means that the bearing inner ring has no abnormality, so the problem lies in the test probe corresponding to the abnormal test probe group number information. In order to facilitate the user to quickly find the test probe group with problems, while outputting the self-abnormal information of the test probe group, the abnormal test probe group number information is also output. At this time, the purpose of outputting the abnormal test probe group number information is not to locate the bearing inner ring with unqualified dimensions, but to locate the test probe group.

[0202] Step 7042: If it does not fall within, output the abnormal test probe group number information and output the bearing inner ring abnormal information.

[0203] The bearing inner ring abnormal information is the information of the abnormal situation on the bearing inner ring. The output method is in the form of text display. If it does not fall within, it means that the bearing inner ring has an abnormality, and the problem lies in the test probe corresponding to the abnormal test probe group number information. Then the abnormal test probe group number information can be normally output for subsequent operations of the system.
