Detailed Description
The invention is further described with reference to the following description and specific examples.
In the prior art, the press fitting of the plug cover of the engine is basically completed by manual labor, but the following defects exist: the blocking cover bonding and the force and the amount between press mounting are different due to the physical state of workers and the use force between different workers during the press mounting of the blocking cover in the labor processing, so that the qualification rate of products cannot be ensured; meanwhile, under a certain specific scene, for example, military enterprises have a limit on the number of workers working in one workshop at the same time, and the operation of other production stations is seriously influenced, so that the overall production takt is prolonged.
Simultaneously, also have the equipment that uses the pressure equipment of mechanical type blanking cover among the prior art, but its work efficiency is low, analyzes its reason: the existing mechanical type plugging press-fitting equipment adopts unified management, namely products are placed together, plugging is carried out together after the products are placed according to a preset plan, namely each process is processed in a unified time, and time and space are not fully managed and utilized, so that the efficiency is not high.
Example 1
In order to solve the above technical problem, the present embodiment provides a method for press-fitting a plug of an engine cylinder block, as shown in fig. 1, including the following steps:
generating a first execution instruction or a first stopping instruction based on the first placing area state, and updating to obtain a second placing area state;
generating a second execution instruction or a second stopping instruction by combining the state of the second placing area to update to obtain the state of a second detection area based on the state of the first detection area; generating a third execution instruction or a third stopping instruction by combining the state of the second detection area and the detection standard, and updating to obtain the state of a third placement area;
generating a fourth execution instruction or a fourth stopping instruction by combining the third placing area state based on the first cover stock state, and updating to obtain a fourth placing area state and a second cover stock state;
generating a fifth execution instruction or a fifth stopping instruction by combining the fourth placing area state based on the first weight stock state, and updating to obtain a fifth placing area state and a second weight stock state;
and establishing a model based on the current state of the placement area, the current state of the detection area and the current state of the inventory, calling a corresponding instruction, and realizing the switching between the execution instruction and the suspension instruction.
In this embodiment, place the platform, examine test table and lid, weight and be a plurality of, arrange according to predetermined order in placing district, detection zone, lid storehouse and the weight storehouse to input every in advance and place the platform, examine test table and lid, the corresponding position coordinate of weight or position number, its purpose is for the convenience of discerning the position that is minimum with current three-dimensional motion module distance. It should be noted that the placement space of the minimum position is, if identified by coordinates: obtaining the minimum distance by calculating according to the preset route; if the identification is carried out according to the position number: the placement vacancy of the minimum position is determined according to the minimum number. The method is suitable for determining the minimum positions of the placing table, the detecting table, the cover body and the weight in the embodiment.
In a further embodiment, the engine to be plugged is placed on the placing table in the placing area from the start of the plugging program, then the engine to be plugged is transferred to the detection of the detection area for detection when detection is needed, the qualified engine to be plugged is transferred to the placing area again, and then operations such as capping, code putting, code fetching and the like are realized according to the inventory. In the whole process, aiming at a single engine or a single placing table, under the condition that all the conditions of cover blocking and code releasing are met, the engine on the single engine or the single placing table can be smoothly placed, detected, covered and released until the code fetching is finished. However, in the process of implementing the operation, problems such as unqualified detection, insufficient inventory, even system error report, and the like generally occur. In this case, the states of the placement area, the detection area, and the inventory are changed accordingly, and the instruction for a single engine or a single placement table is different according to the current state, so that a model needs to be created by starting, a corresponding instruction is called, and switching between an execution instruction and a stop instruction is realized.
In this embodiment, the first placement area state at least includes: placing empty bits and/or placing full bits; wherein the placement vacancy indicates that there is a free placement stage in the current placement zone, i.e., the free placement stage is marked as a placement vacancy. The full placement position indicates that no idle placement platform exists in the current placement area, namely, products are placed on each placement platform, and other corresponding instructions are executed according to different schedules of each product.
Based on the above description, the conditions for generating the first execution instruction are as follows: if a placement vacancy exists in the current placement area, the system inputs first execution information { starting placement and placing vacancy at the minimum position } aiming at the placement vacancy; the first execution information is used for triggering a first execution instruction. In other words, the first execution information includes at least the following amounts of information: and transferring the products to be blocked on the conveying line to a placing vacancy of the placing table, wherein the placing vacancy is the identified placing vacancy at the minimum position, after transferring the products to be blocked on the conveying line to the appointed placing table according to the first execution information, updating the placing vacancy of the currently placed table in the initial state information of the placing table to the position to be detected, and updating to obtain a second placing area state. That is, the placing area in the second placing area state at least comprises a position to be detected, namely, the cover plugging engine on the placing table can be subjected to the next process: and (6) detecting.
The conditions for generating the first abort instruction are as follows: products are placed on each placing table of the current placing area, and first stopping information { stopping placing and insufficient placing vacant } is input according to the full placing position; the first abort information is used to trigger a first abort instruction. The system determines, through the first suspension information, that the reason for suspending the product placement is that the placement vacancy is insufficient, and the current placement vacancy is vacated after the subsequent rejection or boxing process occurs, and the model identification unit calls a corresponding first execution instruction, which will be specifically mentioned below. That is, once the current placing table is occupied by the product to be plugged, the product cannot be transferred until the plugging pressing is completed unless a certain index is detected in the middle and is rejected, and the placing table is a placing vacancy after the product is transferred.
Or when other reasons exist, the system reports error information { abort put, failure to acquire information }, and the system reports error information also used for triggering the first abort instruction. The system determines that the reason for suspending the product placement is other system reasons through the system error reporting information, so that the system starts to detect and troubleshoot the product when the system receives the input system error reporting information.
Based on the above description, the presence of the site to be detected already in the placement area (the state of the second placement area) means that the detection process needs to be performed. Before the detection process is executed, whether the lower detection area meets the detection condition needs to be confirmed: the first detection zone state includes at least: empty bits are detected and/or full bits are detected. The detection vacant position indicates that the current detection platform is in an idle state and can be used for placing products to provide detection support. And detecting a full bit indicates that the current detection platform is in an occupied state, so that the following three conditions can occur in the same detection area: all empty bits are detected, all full bits are detected, or both empty bits and full bits are detected.
However, in either case, the second execution instruction and the second abort instruction are generated for a single bit to be detected or a single engine to be capped.
The concrete expression is as follows: the second execution instruction is generated as follows: aiming at the detection vacancy, if a position to be detected exists in the state of the second placing area, second execution information { starting first transfer, position to be detected-minimum position detection vacancy } is input; the second execution information is used for issuing a second execution instruction. Wherein initiating the first transition means: transferring the product on the position to be detected to a detection vacancy for realizing form and position tolerance detection of the product; the to-be-detected position-minimum position detection vacancy indicates that a product on the to-be-detected position is transferred to a detection vacancy of a current small position, and the determination of the minimum position detection vacancy can be realized through numbers or coordinates. After the transfer is completed, namely the product at the moment is located on the detection vacancy in the detection area, the current detection vacancy is adjusted to be the detection return position to be detected, and the second detection area state is obtained through updating, namely the second detection area state at least comprises the detection table to be the detection return position to be detected, and the next step is to take back.
The second abort instruction is generated as follows: when a detection vacancy exists, if a bit to be detected does not exist in the state of the second placing area, second stopping information { stopping the first transfer, and having no bit to be detected } is input; the second abort information is used to initiate a second execution instruction. The reason the system records the current suspension of the transfer is that there is no product currently in need of inspection. And when the position to be detected is obtained in the state of the second placement area at a certain time point in the future, a newly added product to be detected is indicated, the model is started, the current second stop instruction is switched into a second execution instruction by the model, and the detection process is started.
For detecting a full bit, a seventh abort message { abort first transition, no empty bit detected } is input, which is also used to trigger a second abort instruction. The reason that the system records the current suspension of the transfer is that no inspection station capable of preventing the products to be inspected exists at present. And when the updated detection vacant position in the second detection area state at a certain time point in the future indicates that a new idle detection platform exists, starting the model, switching the current second stop instruction into a second execution instruction by the model, and starting the detection process.
Based on the above description, the detection table in the second detection area state has the return position to be detected, so that the form and position tolerance detection is started for the return position to be detected, the detection instruction detects the form and position tolerance of the product, and the tolerance threshold value meeting the requirement is preset in advance, if the form and position tolerance value obtained by detection is within the tolerance threshold value range, the detection result meets the detection standard, otherwise, the detection result does not meet the requirement.
Based on the detection result, the product that is located the return of waiting to examine to get is handled: judging whether the detection result of the product to be detected on the return accords with the detection standard or not: if yes, inputting third execution information { starting second transfer, to-be-detected return-to-be-detected bit }; the third execution information is used for triggering a third execution instruction. In this embodiment, the second transfer is to transfer qualified products to the placing area from the position to be detected and retrieved in the detection area, the position to be detected indicates that the current products to be detected on the position to be detected return to the original position to be detected according to the original route, and the state of the position to be detected on which qualified products to be detected are placed again is adjusted to the position to be covered, so as to obtain the state of the third placing area, that is, the placing table in the state of the third placing area at least includes the position to be covered, indicating that the next step of the products on the placing table is covered.
For example, the following steps are carried out: before the second execution instruction is executed, the number of the position to be detected is 2, after the second execution instruction is executed, the product with the detection result meeting the detection standard is returned to the position to be detected with the number of 2 according to the original way, the state of the position to be detected with the number of 2 is adjusted to be the position to be blocked, and meanwhile, the state of the third placing area is updated. And meanwhile, the current bit to be retrieved is changed into a detection vacancy, a second detection area state is obtained through updating, at the moment, the model is started, and a second stopping instruction generated due to second stopping information { stopping the first transfer and having no detection vacancy } is switched into a second execution instruction.
And if the detected result is unqualified, namely the detection standard is not met, inputting third stopping information { product offline, to-be-detected return-to-be-detected position, to-be-detected position-placing vacancy }, wherein at the moment, a newly-increased placing vacancy in the state of the third placing area starts a switching model aiming at the newly-increased placing vacancy, and the first execution instruction is switched to. The third suspension information is used for triggering a third suspension instruction, and in this embodiment, the product is off-line, and an unqualified product is transferred out by adopting other modes through a line body. At the moment, the to-be-detected return position corresponding to the unqualified product is adjusted to be a to-be-detected vacancy, the to-be-detected return position is in an idle state, namely, a detection table for placing the to-be-detected product is additionally arranged, so that a second detection area state is obtained through updating, at the moment, the model is started, and a second stopping instruction generated due to second stopping information { stopping the first transfer, and having no detection vacancy } is switched to be a second execution instruction.
Meanwhile, because unqualified products are not transferred to the position to be detected in the placing region any more, the state of the position to be detected is adjusted to be the placing vacancy, namely the placing region is newly added with the placing vacancy at the moment, and a first stopping instruction generated by first stopping information { stopping placing, insufficient placing vacancy } is switched into a first execution instruction aiming at a newly added placing vacancy starting model.
For example, the following steps are carried out: before the third execution instruction is executed, the serial number of the position to be detected is 3, the product is found to be an unqualified product through detection, so that the product is transferred out through the line, meanwhile, the corresponding return position to be detected is updated to be a detection vacancy, and the second stop instruction is switched to be a second execution instruction aiming at the detection vacancy. Meanwhile, the number 3 in the placement area is adjusted from the bit to be detected to a placement vacancy, and the first pause instruction is switched to the first execution instruction for the placement vacancy.
Based on the above description, the placing table in the third placing area state at least includes the position to be blocked, so that the corresponding product in the state of the position to be blocked needs to be blocked, and the analysis is preferably performed based on the cover body inventory, which includes the full cover body position or the empty cover body position. Wherein the full position of the cover body indicates: the number of the cover bodies in the current inventory is larger than or equal to the number of the cover positions to be blocked. The number of the cover bodies in the current inventory is smaller than that of the current positions to be covered, when the products on the partial positions to be covered need to wait for the cover bodies, the distributed positions to be covered which need to wait are called cover body vacant positions.
When the capping flow is executed, the fourth execution instruction is generated under the following conditions: aiming at the full position of the cover body, if the position to be blocked exists in the state of the third placing area, fourth execution information { starting blocking, minimum position cover body } is input; wherein the fourth execution information is used to trigger a fourth execution instruction. In other words, the cover body in the cover blocking area is transferred to the placing area in a state of being on the position to be blocked, and the cover body with the smallest position is selected. And after the cover blocking is finished, adjusting the corresponding position to be blocked into a position to be released, and updating to obtain a fourth placing area state, namely, at least the position to be released exists in the fourth placing area state, which indicates that the next step is a releasing process.
The fourth suspend instruction is generated on the condition that: and inputting eighth suspension information { suspension blockage, insufficient blockage stock }, wherein the eighth suspension information is also used for triggering a fourth suspension instruction, and the reason for system entry and end cover suspension is that the stock of the cover body is insufficient. At a certain future time point, if the cover is supplemented in the stock, the current cover vacancy is switched to be satisfied by the cover, the model is started, the current fourth stopping instruction is switched to be the fourth execution instruction, and the cover blocking is started.
If the third placing area does not have the position of the to-be-blocked cover, fourth stopping information { stopping the blocking, and having no to-be-blocked product } is input; the fourth suspension information is used for triggering a fourth suspension instruction. The reason for the system logging, terminating the end caps, is that there is no product requiring a cap closure. And if the new position to be covered is obtained by updating in the state of the third placing area at a certain future time point, the starting model switches the current fourth stopping instruction into a fourth executing instruction to start covering.
Based on the above description, when there is at least to wait to put the sign indicating number position in the district state is placed to the fourth, then need open and put the sign indicating number flow, also need put the sign indicating number to consequently needing to put the corresponding product of sign indicating number position for waiting to put the state, first-selected analysis based on weight stock, weight stock includes full position or the weight vacancy of weight. Wherein the full weight indicates: the number of the weights in the current inventory is more than or equal to the number of the current code positions to be placed. The number of the weights in the current inventory is smaller than the number of the current positions to be placed, when the weights exist, part of products on the positions to be placed need to wait, and the positions to be placed which are distributed and need to wait are called weight vacancies.
When the code-placing flow is executed, the generation condition of the fifth execution instruction is as follows: aiming at the full position of the weight, if the position to be released exists in the state of the fourth placing area, inputting fifth execution information { starting releasing, minimum position weight }; wherein the fifth execution information is used to trigger a fifth execution instruction. In other words, the weight in the code placing area is transferred to the code placing area, the state of the weight is to be the code position to be placed, and the weight with the minimum position is selected for use. And after the code is played, adjusting the corresponding code to be played to the code to be fetched, and updating to obtain a fifth placing area state, namely, at least the code to be fetched exists in the fifth placing area state, which indicates that the next code fetching process is performed.
The generation condition of the fifth suspend instruction is as follows: and inputting fifth stopping information { stopping code release, insufficient code release inventory } aiming at the empty position of the weight. The fifth suspension information is used for triggering a fifth suspension instruction. And (4) system entry, namely, the reason for stopping the code placement is that the stock of the weights is insufficient. And at a certain future time point, if the weights are replenished in the stock, the current weight vacancy is switched to be satisfied by the weights, the model is started, the current fifth stopping instruction is switched to be a fifth execution instruction, and the code release is started.
If the fourth placing area does not have the position to be placed, inputting ninth stop information { stop placing, no product to be placed }; the ninth suspension information is used to trigger a fifth suspension instruction. The reason for the system to enter and stop the code putting is that no product needs to be put. And if the fourth placing area state is updated to obtain a new position to be placed at a certain future time point, the starting model switches the current fifth stopping instruction into a fifth executing instruction and starts to place the code.
In order to facilitate the every continuous use of placing the platform in later stage and ensure to enter into next set of blanking cover pressure equipment smoothly after accomplishing current blanking cover pressure equipment, this embodiment still includes:
and generating a sixth execution instruction or a sixth stopping instruction by combining the second weight stock state based on the fifth placing area state, and updating to obtain a sixth placing area state and a third weight stock state.
And judging a related instruction for executing code fetching based on the inventory state of the second weight. After the fifth execution instruction is executed, the inventory state of the second weight is the full weight, namely, no free position in the inventory is used for placing the weight, so that tenth stop information { stop code fetching, no weight vacancy } is input, the code fetching is suspended, the reason is that no vacancy is in the weight inventory, and the tenth stop information is also used for triggering a sixth stop instruction. When the empty position appears when the weight in the stock is taken out in the later stage, then adjust current weight full amount to the weight vacancy, show that the empty position exists at present and be used for placing the weight, can take back the weight that is located on the engine.
And based on the description, or the second weight stock state is originally a weight vacancy, judging the current output instruction based on the state of the fifth placing area.
