Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited to these examples.
Before describing the embodiments of the present invention in detail, a brief description of the mistake-proof stapling box will be given. Mistake proofing dress nail case is including sweeping yard subassembly, first subassembly and the second subassembly of weighing, and the screw is generally loaded in the packing carton in advance, and the recognition code that has corresponding the interior screw model of packing carton in advance printed on the packing carton lateral wall. The code scanning assembly is used for scanning the identification codes before loading to detect the models of the screws, the second weighing assembly is used for weighing and detecting the packaging boxes and the screws before loading to identify the models and the quantities of the screws from the weight dimension, and the first weighing assembly is used for weighing and detecting the screws when loading to identify the models and the quantities of the screws from the weight dimension. The first weighing component and the second weighing component are different mainly in that the first weighing component is used for weighing and detecting the screw independently, and the second weighing component is used for weighing and detecting the screw and the packaging box loaded with the screw together.
As shown in fig. 1, the second weighing assembly is located at a preparation station 1, and the first weighing assembly is located inside the error-proof nail box and located at a loading station 2. It should be noted that, since the mechanical structures of the code scanning assembly, the first weighing assembly, the second weighing assembly and the error-proof nail box are not the main points of the present invention, the structural views of the code scanning assembly, the first weighing assembly, the second weighing assembly and the error-proof nail box are not shown in fig. 1.
Example 1
The embodiment provides a screw loading control method which is mainly used for controlling a code scanning assembly, a first weighing assembly and a second weighing assembly in a mistake-proofing stapling box so as to realize loading operation and loading detection of screws by matching with the screws. Referring to fig. 2, the control method specifically includes the following steps:
s01: the code scanning component scans and verifies the identification code;
s02: if the code scanning verification result is correct, controlling the mistake-proofing nail box to open the cover;
s03: when the screws reach the loading station 2 in the error-proof nail box, performing first weighing verification on the screws through a first weighing assembly;
s04: and if the first weighing verification result is correct, controlling the error-proof screw box to load the screw.
In an exemplary embodiment, the pack loaded with screws may be placed on the preparation station 1 manually or robotically to be considered as the arrival of screws at the preparation station 1. When the packing carton that loads the screw arrives and prepares station 1, sweep the sign indicating number verification to the identification code on the packing carton lateral wall automatically of sign indicating number subassembly.
The code scanning component can be preset and arranged around the preparation station 1, and the code scanning range of the code scanning component covers the preparation station 1 so as to realize the function of code scanning verification of the identification code on the preparation station 1. For example: the code scanning assembly is arranged on one side of the preparation station 1, and when the packing box loaded with the screws arrives at the preparation station 1, the packing box is rotated or pre-rotated before arriving so that the identification code is aligned with the code scanning assembly, and the code scanning assembly can be used for code scanning verification of the identification code. Or the code scanning assembly can also be used for carrying out displacement code scanning in a manual mode or a mechanical arm automatic mode. For example: the code scanning assembly is held on a hand or a mechanical arm in advance, and when the packing box loaded with the screws reaches the preparation station 1, the code scanning assembly is moved manually or automatically by the mechanical arm to align the code scanning assembly with the identification code, so that the code scanning assembly can verify the code scanning of the identification code.
After code scanning verification is completed, the code scanning component transmits a code scanning verification result to the background server, and the result is verified through the server. The server is pre-stored with corresponding relations of different code scanning assemblies and identification codes corresponding to the different code scanning assemblies. It can be understood that one code scanning component only corresponds to the identification code of one screw model or a plurality of screw signals, if the identification code scanned by the code scanning component is not in the range of the identification code of the corresponding relation of the code scanning component in the server, the verification is represented to be wrong, and if the identification code scanned by the code scanning component is in the range of the identification code, the verification is represented to be correct.
When the error is verified, the error-proof nailing box sends an alarm to prompt a nailing error; and when the verification is correct, controlling a second weighing assembly on the preparation station 1 to carry out second weighing verification on the packaging box loaded with the screws and the screws in the packaging box. The second weighing component can be selected as an electronic weighing device, and when the code scanning verification result is correct, the second weighing component is started and carries out second weighing verification on the packaging box and the screw.
In an exemplary embodiment, the second weighing verification mainly functions to detect the number of screws for fixing the package (a package box is internally and fixedly provided with a fixed number of screws) and the type of the screws corresponding to the identification code, and although the identification code of the package box is verified correctly, because the identification code is not arranged on the screws, in order to ensure that the correct type and number of screws are loaded in the package box with the correct identification code, the second weighing verification can be performed on the weight of the package box and the screws by using the second weighing assembly, and whether the screws corresponding to the correct type and number are loaded in the package box with the correct identification code is obtained according to the result of the second weighing verification. It should be noted that different types of screws generally refer to screws with different lengths, thicknesses, materials, shapes, etc., that is, different types of screws may have different weights due to different types, so different types of screws can be detected by weighing detection, and generally, one or more packaging boxes can detect the number of screws required for assembly for a fixed number of times (the number of screws required for one assembly operation is fixed, for example, one or more boxes of screws can be used for one or more assembly operations), and the number of screws can also be detected by weighing detection (total screw weight/single screw weight = number of screws), so as to ensure that the screws are sufficiently supplied during the assembly operation for the fixed number of times, and avoid the phenomena of screw missing and wrong screws.
Further, if the second weighing verification result is correct, the mistake-proofing nailing box is controlled to open the cover body for uncovering operation, and screws are taken out of the packaging box and are loaded into the mistake-proofing nailing box. When the screws are loaded into the error-proof magazine, the screws are considered to arrive at the loading station 2.
After the second weighing verification result is correct, the screws can be taken out of the packaging box and put into the mistake-proofing nailing box. If the preparation station 1 is arranged at a position far away from the error-proof nail box, in the process of moving the packing box to the error-proof nail box after the packing box is moved or taken out of the screw, the screw or the packing box may fall or fall to cause the phenomena of screw damage, loss and the like, so the preparation station 1 can be arranged at the cover body side of the error-proof nail box, and the screw can be directly assembled into the error-proof nail box from the cover opening side after the cover opening operation is completed. For example: the cover body of the mistake-proofing binding box is arranged on the upper side wall of the mistake-proofing binding box, the preparation station 1 can be arranged on the upper side wall of the mistake-proofing binding box in the same mode, namely the second weighing assembly and the code sweeping assembly are arranged on the upper side wall of the mistake-proofing binding box, the packing box loaded with the screws is placed on the preparation station 1 of the upper side wall of the mistake-proofing binding box, the codes of the packing box and the screws can be swept, the second weighing verification is carried out, after the verification is correct, the packing box is unpacked, the screws are directly poured into the mistake-proofing binding box, and the screws can reach the loading station 2.
At this point, the code scanning verification and the second weighing verification are completed.
In the exemplary embodiment, the loading station 2 is located inside the error-proof nail box and at the bottom of the box, i.e. after the screws are poured into the error-proof nail box, the screws fall into the bottom of the box and are considered as the screws reaching the loading station 2. As shown in fig. 1, if the preparation station 1 is provided on the upper side wall of the error-proofing nail magazine, the preparation station 1 is located right above the loading station 2 in the height direction. In addition, the possibility that the preparation station 1 is arranged on the other side of the error-proof nailing box is not excluded.
And when the screws reach the loading station 2, controlling the first weighing assembly to carry out first weighing verification on the screws. Wherein, the first weighing component can be the electronic weighing ware of the same selection, and when the screw arrived loading station 2, the first weighing component started to carry out weighing detection to the screw.
After the second weighing verification, the main function of weighing again for the first weighing verification is to avoid that the screws in one fixed package are not completely loaded in the error-proof nail box, namely, the phenomena of missing loading and less loading are avoided in the process of taking out the screws from the packaging box and pouring the screws into the error-proof nail box. It can be known that the difference range between the first weighing verification and the second weighing verification is the weight value of the packaging box. For example: if the weight value of the packaging box is A and the weight values of all the screws in the packaging box are B (excluding the weight of the packaging box), the result of the first weighing verification is A + B, and the result of the second weighing verification is B. Preferably, on the basis of a, a value between 0.5 g or 1g of the lower and upper floats is used as a difference range, or the difference range can be preset according to practical situations, and is not limited in particular. The verification process of the results of the first weighing verification and the second weighing verification is the same as the verification process of the results of the code scanning assembly in principle, and therefore the detailed description is omitted.
Further, the loading station 2 is further provided with a regulating assembly, and when the second weighing verification result is correct, the regulating assembly is controlled to carry out loading operation on the screws on the loading station 2, so that the screws are loaded in the mistake-proofing nail box in a regular arrangement mode. Wherein, the regular assembly can be selected as a mechanism with a rotating function, and screws are orderly arranged and loaded in the mistake-proof nail box by utilizing the rotating centrifugal force.
After the loading operation is finished, the mistake-proofing stapling box cover body is controlled to move to close the cover, and foreign objects are prevented from entering the mistake-proofing stapling box.
Thus, the first weighing verification and loading operation is completed.
In an exemplary embodiment, the corresponding error-proof stapling box is further provided with a counting assembly. Above-mentioned sweep a yard verification and weigh and verify that preferred screw to single box packing carton loads and detects, when the screw that needs to many boxes of packing carton loads and detects, when sweeping a yard subassembly and sweeping yard verification in proper order to the identification code on many boxes of packing carton through sweeping a yard subassembly, accessible counting assembly is to sweeping yard number of times of sweeping a yard subassembly and counting the operation, can detect the loading of many boxes of packing carton through counting the operation, can learn this time and swept yard detection to how many boxes of packing carton altogether. It should be noted that usually a mistake-proof binding box only loads a single type of screw, i.e. the identification code of the code scanning assembly corresponding to the mistake-proof binding box is usually unique in the server, i.e. the number and weight of screws corresponding to and pre-loaded in a single packing box are also unique.
When screws of a multi-box packaging box are loaded and detected, the results of the first weighing verification and the second weighing verification are correlated with the times of statistical operation to perform result verification. For example: the weight of a single packing box is A, and the weight value of all screws in the single packing box is B (excluding the weight of the packing box); when screws of a packaging box 1 are loaded, code scanning verification is required for 1 time, namely the number of times of statistical operation is 1 time, the correct result of the first weighing verification is A + B, and the correct result of the second weighing verification is B; when screws of 2 boxes of packaging boxes are loaded, code scanning verification is required for 2 times, namely the number of times of statistical operation is 2 times, the correct result of the first weighing verification is 2 (A + B), and the correct result of the second weighing verification is 2B; by analogy, the following steps are known: when screws of n boxes of packaging boxes are loaded, the code scanning verification is needed for n times, namely the number of times of the statistical operation is n times, the correct result of the first weighing verification is n (A + B), and the correct result of the second weighing verification is nB. The counting assembly can be used for simultaneously carrying out loading detection on screws of a single box or a plurality of boxes when the screws are loaded at one time, so that the loading efficiency is improved, and the loading accuracy is ensured.
This embodiment carries out dual detection through sweeping yard subassembly, second weighing component, first weighing component and counting assembly before the screw loads and when loading, ensures that the model and the quantity that the screw loaded are correct, and is applicable to single box and many boxes of packing carton screw and loads and detect, avoids phenomenons such as few nail, wrong nail to take place, effectively improves loading efficiency.
Example 2
Including the entire contents of the above-described embodiment 1
In an exemplary embodiment, the mistake-proofing nailing box is used for conveying screws to the assembling mechanism so as to realize the nailing operation on the assembling mechanism, and the assembling mechanism is used for carrying out the assembling operation on the workpiece so as to realize the fixing, fastening and other effects on the workpiece. Preferably, a transparent pipe is connected between the assembling mechanism and the error-proof nail box to form a transmission channel between the assembling mechanism and the error-proof nail box, and the screws in the error-proof nail box can be conveyed or loaded in the assembling mechanism through the transmission channel. Simultaneously, be equipped with the subassembly of blowing in mistake proofing binding case, the mouth and the transfer passage intercommunication of blowing of the subassembly of blowing, and the direction of blowing of the subassembly is the direction that mistake proofing binding case is close to assembly devices, can carry the screw in the mistake proofing binding case to transfer passage, assembly devices in proper order through the mode of blowing through the subassembly of blowing to realize the screw from mistake proofing binding case to assembly devices's transport operation. The position of the assembling mechanism or the position where the assembling mechanism performs operation is an assembling station 3, namely, screws in the mistake-proof nail box can be conveyed or loaded on the assembling station 3 through the conveying channel and the air blowing assembly.
Further, in order to avoid the error of the verification results of the first weighing verification and the second weighing verification and ensure that the screws required by the assembly operation are preset during the conveying operation, a screw detector (not shown in the figure) is installed on the transparent pipeline, and when the screws pass through the transparent pipeline, the normal conveying operation is recorded. Meanwhile, the screw detector can count the number, namely the model, of the screws supplied during the conveying operation according to the times and duration of the screws passing through the transparent pipeline. For example: when a screw passes through the transparent pipeline every time, the screw detector counts one screw; another example is: when the screw models are different (the lengths are different), the screw detector can count by the time when the screw passes through the screw detector, such as: screws of the longer type pass the screw detector for a longer time, while screws of the shorter type pass the screw detector for a shorter time.
The embodiment realizes that the screws are conveyed to or loaded onto the assembly mechanism from the mistake-proofing nail box through the conveying channel, the screw detector and the air blowing assembly, and further detects the number and the type of the screws during conveying through the screw detector during conveying operation, so that the screws required by the assembly operation are ensured, and the accuracy and the efficiency of the assembly operation are ensured.
Example 3
This embodiment provides a screw loading control system, controls the yard subassembly of sweeping, first subassembly of weighing, the second subassembly cooperation screw in the mistake proofing binding case. As shown in the combined figure, the control system comprises a code scanning module 4, a first verification module 5, a weighing module 6 and a second verification module 7.
The code scanning module 4 is used for the code scanning component to scan and verify the identification code;
the first verification module 5 is used for controlling the mistake-proofing nail box to open the cover if the code scanning verification result is correct;
the weighing module 6 is used for carrying out first weighing verification on the screws through the first weighing assembly when the screws reach the loading station 2 in the mistake-proofing nail box;
and if the first weighing verification result is correct, the second verification module 7 controls the mistake-proofing screw box to load the screw.
In an exemplary embodiment, the packing box loaded with the screws may be placed on the preparation station 1 in a manual manner or in an automatic manner by a robot as the screws arrive at the preparation station 1. When the packing carton that loads the screw arrives and prepares station 1, sweep a yard module 4 control and sweep a yard subassembly and automatically sweep a yard to the identification code on the packing carton lateral wall and verify.
After the code scanning verification is completed, the code scanning assembly transmits the result of the code scanning verification to the first verification module 5, and the result is verified through the first verification module 5. The first verification module 5 stores in advance the correspondence between different code scanning assemblies and the identification codes corresponding to the different code scanning assemblies. It can be understood that one code scanning component only corresponds to the identification code of one screw model or a plurality of screw signals, if the identification code scanned by the code scanning component is not in the range of the identification code of the corresponding relation of the code scanning component in the first verification module 5, the verification is represented as wrong, and if the identification code is in the range, the verification is represented as correct.
When the error is verified, the first verification module 5 initiates an alarm to prompt the stapling error; when the verification is correct, the first verification module 5 controls the second weighing assembly on the preparation station 1 to carry out second weighing verification on the packaging box loaded with the screws and the screws in the packaging box. The second weighing component can be selected as an electronic weighing device, and when the code scanning verification result is correct, the second weighing component is started and carries out second weighing verification on the packaging box and the screw.
In an exemplary embodiment, the second weighing verification mainly functions to detect the number of screws for fixing the package (a package box is loaded with a fixed number of screws) and the type of the screws corresponding to the identification code, and although the identification code of the package box is verified correctly, since the identification code is not set on the screws, in order to ensure that the correct identification code is loaded with the screws corresponding to the correct type and number in the package box, the second weighing component can be used to perform the second weighing verification on the weight of the package box and the screws, and whether the correct identification code is loaded with the screws corresponding to the correct type and number in the package box is obtained according to the result of the second weighing verification. It should be noted that different types of screws generally refer to screws with different lengths, thicknesses, materials, shapes, etc., that is, different types of screws may have different weights, so different types of screws may be detected by weighing detection, and usually one or more packaging boxes may have the number of screws required for assembly for a fixed number of times (the number of screws required for one assembly operation is fixed, for example, one or more boxes of screws may be used for one or more assembly operations), and the number of screws may also be detected by weighing detection (total weight of screws/weight of single screw = number of screws), so as to ensure sufficient supply of screws during the assembly operation for the fixed number of times, and avoid the phenomena of missing screws and wrong screws.
Further, if the second weighing verification result is correct, the first verification module 5 controls the mistake-proofing nailing box to open the cover body for uncovering operation, and takes out the screws from the packaging box and puts the screws into the mistake-proofing nailing box. When the screws are loaded into the error-proof magazine, it is assumed that the screws arrive at the loading station 2.
After the second weighing verification result is correct, the screws can be taken out of the packaging box and put into the mistake-proofing binding box. If the preparation station 1 is arranged at a position far away from the error-proof nail box, in the process of moving the packing box to the error-proof nail box after the packing box is moved or taken out of the screw, the screw or the packing box may fall or fall to cause the phenomena of screw damage, loss and the like, so the preparation station 1 can be arranged at the cover body side of the error-proof nail box, and the screw can be directly assembled into the error-proof nail box from the cover opening side after the cover opening operation is completed. For example: the cover body of the mistake-proofing binding box is arranged on the upper side wall of the mistake-proofing binding box, the preparation station 1 can be arranged on the upper side wall of the mistake-proofing binding box in the same mode, namely the second weighing assembly and the code sweeping assembly are arranged on the upper side wall of the mistake-proofing binding box, the packing box loaded with the screws is placed on the preparation station 1 of the upper side wall of the mistake-proofing binding box, the codes of the packing box and the screws can be swept, the second weighing verification is carried out, after the verification is correct, the packing box is unpacked, the screws are directly poured into the mistake-proofing binding box, and the screws can reach the loading station 2.
At this point, the code scanning verification and the second weighing verification are completed.
In the exemplary embodiment, the loading station 2 is located inside the error-proof nail box and at the bottom of the box, i.e. after the screws are poured into the error-proof nail box, the screws fall into the bottom of the box and are considered as the screws reaching the loading station 2. When the screws reach the loading station 2, the weighing module 6 controls the first weighing component to carry out first weighing verification on the screws. Wherein, the first weighing component can be the electronic weighing ware of the same selection, and when the screw arrived loading station 2, the first weighing component started to carry out weighing detection to the screw.
After the second weighing verification, the main function of weighing again for the first weighing verification is to avoid that the screws in one fixed package are not completely loaded in the error-proof nail box, namely, the phenomena of missing loading and less loading are avoided in the process of taking out the screws from the packaging box and pouring the screws into the error-proof nail box. It can be known that the difference range between the first weighing verification and the second weighing verification is the weight value of the packaging box. For example: if the weight value of the packaging box is A and the weight values of all the screws in the packaging box are B, the first weighing verification result is A + B, and the second weighing verification result is B. Preferably, on the basis of a, a value between 0.5 g or 1g of the lower and upper floats is used as the difference range, or the difference range can be preset according to actual conditions, and is not limited in particular. The result of the second weighing verification is sent to the second verification module 7 for verification, and the verification principle is the same as that of the first verification module 5, which is not described in detail.
Further, the loading station 2 is also provided with a regulating assembly, and when the second weighing verification result is correct, the second verification module 7 controls the regulating assembly to carry out loading operation on the screws on the loading station 2, so that the screws are loaded in the mistake-proofing nail box in a neat arrangement. Wherein, the regular assembly can be selected as a mechanism with a rotating function, and screws are orderly arranged and loaded in the mistake-proof nail box by utilizing the rotating centrifugal force.
After the loading operation is finished, the mistake-proofing nail box cover body is controlled to move to close the cover, and foreign objects are prevented from entering the mistake-proofing nail box.
Thus, the first weighing verification and loading operation is completed.
In an exemplary embodiment, the corresponding error-proof magazine is further provided with a counting module 8. Above-mentioned sweep a yard verification and weigh and verify that preferred screw to single box packing carton loads and detect, when the screw that needs to many boxes of packing carton loads and detects, when sweeping a yard subassembly and sweeping yard verification in proper order to the identification code on many boxes of packing carton through sweeping, accessible count module 8 is to sweeping yard number of times of sweeping of a yard subassembly and counting the operation, can detect the loading of many boxes of packing carton through counting the operation, can learn this time and swept yard detection to how many boxes of packing carton altogether. It should be noted that usually, a mistake-proof nailing case only loads a single type of screw, that is, the identification code of the code scanning assembly corresponding to the mistake-proof nailing case is usually unique in the server, that is, the number and weight of screws corresponding to a single packing case and pre-loaded in the single packing case are also unique.
When screws of the multi-box packaging box are loaded and detected, the results of the first weighing verification and the second weighing verification are correlated with the times of the statistical operation to verify the results. For example: the weight of a single packing box is A, and the weight value of all screws in the single packing box is B (excluding the weight of the packing box); when screws of a packaging box 1 are loaded, code scanning verification is required for 1 time, namely the number of times of statistical operation is 1 time, the correct result of the first weighing verification is A + B, and the correct result of the second weighing verification is B; when screws of 2 boxes of packaging boxes are loaded, code scanning verification is required for 2 times, namely the number of times of statistical operation is 2 times, the correct result of the first weighing verification is 2 (A + B), and the correct result of the second weighing verification is 2B; by analogy, the following steps are known: when screws of n boxes of packing boxes are loaded, the number of times of code scanning verification is needed to be n times, namely the number of times of statistical operation is n times, the correct result of the first weighing verification is n (A + B), and the correct result of the second weighing verification is nB. The counting module 8 can be used for simultaneously carrying out loading detection on screws of a single box or a plurality of boxes when the screws are loaded at one time, so that the loading efficiency is improved, and the loading accuracy is ensured.
This embodiment carries out dual detection through sweeping yard subassembly, second weighing component, first weighing component and count module 8 before the screw loads and when loading, ensures that the model and the quantity that the screw loaded are correct, and is applicable to single box and many boxes of packing carton screw and loads and detect, avoids phenomenons such as few nail, wrong nail to take place, effectively improves loading efficiency.
