Detailed ways

The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

Before describing the embodiments of the present invention in detail, a brief description of the erroneous stapling box is given. The error-proof stapling box includes a code scanning component, a first weighing component and a second weighing component. The screws are usually pre-loaded in the packaging box, and the identification code corresponding to the screw type in the packaging box is pre-printed on the outer side wall of the packaging box. The scanning component is used to scan the identification code to identify the type of screws before loading, and the second weighing component is used to check the packaging box and screws before loading to identify the type and quantity of screws from the weight dimension. , the first weighing component is used for weighing and detecting the screws during loading, so as to identify the type and quantity of the screws from the weight dimension. The difference between the first weighing component and the second weighing component is mainly that the first weighing component is used for weighing and testing the screw alone, while the second weighing component is used for weighing the screw together with the packaging box containing the screw. Carry out a weighing test.

As shown in FIG. 1 , the location of the second weighing component is the preparatory station 1 , and the first weighing component is disposed inside the error-proof stapler box and is located at the loading station 2 . It should be noted that, since the mechanical structure of the code scanning assembly, the first weighing assembly, the second weighing assembly and the error-proof stapling box is not the focus of the present invention, the scanning assembly, the first weighing assembly and the first Structural view of the weighing assembly, the second weighing assembly, and the error-proof staple box.

Example 1

This embodiment proposes a screw loading control method, which is mainly used to control the barcode scanning component, the first weighing component, and the second weighing component in the error-proof stapler box, so as to cooperate with the screws to realize the loading operation and loading of the screws. detection. 2, the control method specifically includes the following steps:

S01: The scanning component scans and verifies the identification code;

S02: If the result of the code scanning verification is correct, control the error-proof staple box to open the lid;

S03: When the screw reaches the loading station 2 in the error-proof nailing box, perform the first weighing verification on the screw through the first weighing component;

S04: If the result of the first weighing verification is correct, control the error-proof nailing box to load the screws.

In an exemplary embodiment, the packaging box loaded with screws can be placed on the preparatory station 1 in a manual manner or in an automatic manner by a manipulator, so as to regard the screws arriving at the preparatory station 1 . When the packaging box loaded with screws arrives at the preparatory station 1, the scanning component automatically scans and verifies the identification code on the outer side wall of the packaging box.

Wherein, the code scanning component can be pre-installed around the preparatory station 1, so that the scanning range covers the preparatory station 1, so as to realize the function of scanning and verifying the identification code on the preparatory station 1. For example: install the scan code assembly on one side of the preparatory station 1, when the packaging box loaded with screws arrives at the preparatory station 1, rotate or pre-rotate before arriving to align the identification code with the scan code assembly, so as to Make the code scanning component scan the code to verify the identification code. Alternatively, the code scanning component can also be used to scan the code manually or automatically by a manipulator. For example: the code scanning component is held on the human hand or manipulator in advance. When the packaging box loaded with screws reaches the preparation station 1, the code scanning component is moved manually or automatically by the manipulator to align the code scanning component with the identification code, so that the scanning code can be scanned. Scanning verification of the identification code by the code component.

After completing the scan code verification, the scan code component transmits the scan code verification result to the backend server, and the server verifies the result. The server pre-stores the correspondence between different code scanning components and the identification codes corresponding to the different code scanning components. It can be understood that a code scanning component only corresponds to one screw model or the identification codes of multiple screw signals. If the identification code scanned by the code scanning assembly is not within the range of the identification code of the corresponding relationship of the code scanning assembly in the server, then Characterization validation error, if within its range, characterization validation is correct.

When the verification is wrong, the error-proof stapling box will issue an alarm to remind the stapling error; when the verification is correct, the second weighing component controlled on the preparatory station 1 will carry out the first step on the packaging box loaded with screws and the screws in the packaging box. Two weighing verification. Wherein, the second weighing component can be selected as an electronic weighing device, and when the result of the code scanning verification is correct, the second weighing component is activated and performs the second weighing verification on the packing box and the screw.

In the exemplary embodiment, the main function of the second weighing verification is to detect the number of screws in a fixed package (a fixed number of screws are fixedly loaded in a packaging box) and the screw type corresponding to the identification code, although the above-mentioned packaging box The identification code is verified correctly, but since the identification code is not set on the screw, in order to ensure that the correct type and quantity of screws are loaded in the packaging box with the correct identification code, the second weighing component can be used to measure the weight of the packaging box and the screws. Carry out the second weighing verification, and obtain the correct identification code through the result of the second weighing verification, whether the correct type and quantity of screws are loaded in the packaging box. It should be noted that different types of screws usually refer to screws with different lengths, thicknesses, materials, shapes, etc., that is, due to different types, the weight of screws of different types may be different, so different types of screws can be detected by weighing. Inspection, and usually one or more boxes are the number of screws required for a fixed number of assembly (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), The number of screws can also be detected by weighing detection (total screw weight/single screw weight = number of screws) to ensure that the supply of screws is sufficient during assembly operations for a fixed number of times to avoid missing and wrong nails.

Further, if the result of the second weighing verification is correct, control the error-proof stapler box to open the cover to perform the cover-opening operation, and take out the screws from the packaging box and put them into the error-proof stapler box. When the screw is loaded into the error-proof staple box, it is considered that the screw reaches the loading station 2.

As the result of the second weighing verification is correct, the screws can be taken out of the box and loaded into the error proof staple box. If the preparatory station 1 is located far away from the error-proof stapler box, the screws or the box may be scattered or dropped during the process of moving the packing box or removing the screws and then moving to the error-proof stapler box. Damage, loss and other phenomena, so the preparatory station 1 can be set on the cover side of the error-proof nailing box. After the cover opening operation is completed, the screws can be directly loaded into the error-proof nailing box from the open cover side. For example, if the cover of the error-proof stapling box is set on the upper side wall of the erroneous stapling box, the preparatory station 1 can also be set on the upper side wall of the error-proof stapling box, that is, the second weighing component and the sweeper. The code component is installed on the upper side wall of the error-proof nailing box, and the packaging box loaded with screws is placed on the preparatory station 1 on the upper side wall of the error-proof nailing box, and the packaging box and screws can be scanned and the second Weighing verification, after verification is correct, unpack the packaging box and pour the screws directly into the error-proof nailing box, so that the screws can reach the loading station 2.

So far, the scan code verification and the second weighing verification have been completed.

In the exemplary embodiment, the loading station 2 is located inside the error-proof stapler box and at the bottom of the box, that is, after the screws are poured into the error-proof stapler box, the screws are regarded as reaching the loading station 2 when they fall into the box bottom. With reference to FIG. 1 , it can be seen that if the preparatory station 1 is arranged at the upper side wall of the erroneously-proof stapler box, the preparatory station 1 is located directly above the loading station 2 in the height direction. In addition, it is not excluded that the preparatory station 1 is arranged on other sides of the error-proof stapler box.

After the screw reaches the loading station 2, the first weighing component is controlled to perform a first weighing verification on the screw. Wherein, the first weighing component can be similarly selected as an electronic weighing device. When the screw reaches the loading station 2, the first weighing component starts to perform weighing detection on the screw.

After the second weighing verification, the main function of re-weighing the first weighing verification is to prevent the screws in a fixed package from not being completely Put it into the error-proof nail box, that is, to avoid the phenomenon of missing or less loading. 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 of the box is A, and the weight of all screws in the box is B (excluding the weight of the 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 or 1 g above and below is used as the difference range, or the difference range can be preset according to the actual situation, which is not specifically limited. The principle of the verification process of the results of the first weighing verification and the second weighing verification is the same as that of the verification process of the results of the code scanning component, so it is not repeated here.

Further, the loading station 2 is also provided with a regular assembly. When the result of the second weighing verification is correct, the regular assembly is controlled to load the screws on the loading station 2, so that the screws are neatly arranged and loaded. in an error-proof staple box. Among them, the regular assembly can be selected as a mechanism with a rotating function, and the screws are arranged in an orderly manner and loaded into the error-proof nailing box by using the rotating centrifugal force.

After the loading operation is completed, control the movement of the cover body of the error-proof stapling box to close the cover to prevent foreign objects from entering the error-proof stapling box.

So far, the first weighing verification and loading operation have been completed.

In an exemplary embodiment, the corresponding error-proof stapler is also provided with a counting assembly. The above scanning verification and weighing verification are preferably carried out for loading and testing the screws of the single-box packaging box. When the screws of the multi-box packaging box need to be loaded and detected, the identification code is obtained on the multi-box packaging box through the code scanning component. While performing code scanning verification in sequence, the counting component can be used to count the scanning times of the code scanning component. Through the counting operation, the loading of multiple boxes can be detected, and the total number of boxes can be known this time. Scanning was performed. It should be noted that, usually a wrong-proof staple box only carries a single type of screw, that is, the identification code corresponding to the code scanning component of the error-proof staple box is usually unique in the server, that is, it corresponds to a single packaging box and a single type of screws. The number and weight of screws preloaded in the box are also unique.

When the screws of the multi-box packaging box are loaded and inspected, the results of the first weighing verification and the second weighing verification are correlated with the number of statistical operations to verify the results. For example: the weight of a single box is A, and the weight of all screws in a single box is B (excluding the weight of the box); when loading screws in a box, it is necessary to scan the code to verify once, that is, a statistical operation The number of times is 1, the correct result of the first weighing verification should be A+B, and the correct result of the second weighing verification should be B; times, that is, the number of statistical operations is 2, then the correct result of the first weighing verification should be 2(A+B), and the correct result of the second weighing verification should be 2B; When the screw of the box is loaded, it needs to scan the code for n times, that is, the number of statistical operations is n times, then the correct result of the first weighing verification should be n(A+B), and the correct result of the second weighing verification should be is nB. Through the counting component, the screws of a single box or a multi-box packaging box can be loaded at the same time during one loading, so as to improve the loading efficiency and ensure the loading accuracy.

In this embodiment, the scanning component, the second weighing component, the first weighing component and the counting component perform double detection before and during the loading of the screws to ensure that the type and quantity of the screws loaded are correct, and it is suitable for single box and multiple Box packaging box screw loading detection to avoid the occurrence of missing nails and wrong nails, and effectively improve the loading efficiency.

Example 2

Including the entire content of the above embodiment 1

In an exemplary embodiment, an error-proof stapling box is used to deliver screws to an assembly mechanism to perform stapling operations on the assembly mechanism, and the assembly mechanism is used to assemble a workpiece for fixing, tightening, etc. Effect. Preferably, a transparent pipe is connected between the assembling mechanism and the error-proof stapling box to form a transmission channel between the assembling mechanism and the erroneous stapling box, through which the screws in the error-proof stapling box can be transported or loaded into the assembling mechanism middle. At the same time, an air blowing component is provided in the error-proof stapling box, the air blowing port of the air-blowing component is communicated with the transmission channel, and the blowing direction of the air-blowing component is the direction in which the error-proof stapling box is close to the assembly mechanism, and the air blowing component passes through the air blowing component. The screws in the error-proof stapling box can be transported to the conveying channel and the assembly mechanism in turn by blowing air, so as to realize the conveying operation of the screws from the error-proof stapling box to the assembling mechanism. Wherein, the location where the assembling mechanism is located or where the operation is performed is the assembling station 3, that is, the screws in the error-proof nailing box can be transported or loaded on the assembling station 3 through the conveying channel and the air blowing assembly.

Further, in order to avoid errors in the verification of the results of the first weighing verification and the second weighing verification, and to ensure that the screws supplied during the conveying operation are the preset screws required for the assembly operation, a screw detector ( (not shown in the figure), when there are screws passing through the transparent pipe, it is recorded as normal delivery. At the same time, the screw detector can count the number and model of the screws supplied during the conveying operation according to the number and length of the screws passing through the transparent pipe. For example: every time a screw passes through the transparent pipe, the screw detector counts one; another example: when the screw type is different (different length), the screw detector can count the time when the screw passes through the screw detector, such as: the length of the screw is different. Longer type screws have a longer time to pass the screw detector, while shorter length type screws have a shorter time to pass the screw detector.

In this embodiment, through the conveying channel, the screw detector and the air blowing assembly, the screws are conveyed or loaded from the error-proof nailing box to the assembly mechanism, and the screw detector is used to further check the number of screws and the number of screws during conveying during conveying operation. The model is tested to ensure that the conveying screws are the screws required for the assembly operation, so as to ensure the accuracy and efficiency of the assembly operation.

The code scanning module 4 is used for the scanning code component to scan the code to verify the identification code;

The first verification module 5 is used to control the error-proof staple box to open the cover if the result of the code scanning verification is correct;

The weighing module 6 is used to perform a first weighing verification on the screw through the first weighing component when the screw reaches the loading station 2 in the error-proof nailing box;

If the result of the first weighing verification is correct, the second verification module 7 controls the error-proof nailing box to load the screws.

In an exemplary embodiment, the packaging box loaded with screws can be placed on the preparatory station 1 in a manual manner or in an automatic manner by a manipulator, so as to regard the screws arriving at the preparatory station 1 . When the packaging box loaded with screws arrives at the preparatory station 1, the code scanning module 4 controls the code scanning component to automatically scan and verify the identification code on the outer side wall of the packaging box.

After completing the scan code verification, the scan code component transmits the result of the scan code verification to the first verification module 5, and the first verification module 5 verifies the result. The first verification module 5 pre-stores the correspondence between different code scanning components and the identification codes corresponding to the different code scanning components. It can be understood that a code scanning component corresponds to only one screw model or the identification code of multiple screw signals. If the identification code scanned by the scanning code assembly is not in the first verification module If it is within the range, it means that the verification is wrong, and if it is within its range, it means that the verification is correct.

When the verification is wrong, 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 preparatory station 1 to load the packing box with screws and the inside of the packing box. screw for a second weighing verification. Wherein, the second weighing component can be selected as an electronic weighing device, and when the result of the code scanning verification is correct, the second weighing component is activated and performs the second weighing verification on the packing box and the screw.

In the exemplary embodiment, the main function of the second weighing verification is to detect the number of screws in a fixed package (a fixed number of screws are fixedly loaded in a packaging box) and the screw type corresponding to the identification code, although the above-mentioned packaging box The identification code is verified correctly, but since the identification code is not set on the screw, in order to ensure that the correct type and quantity of screws are loaded in the packaging box with the correct identification code, the second weighing component can be used to measure the weight of the packaging box and the screws. Carry out the second weighing verification, and obtain the correct identification code through the result of the second weighing verification, whether the correct type and quantity of screws are loaded in the packaging box. It should be noted that different types of screws usually refer to screws with different lengths, thicknesses, materials, shapes, etc., that is, due to different types, the weight of screws of different types may be different, so different types of screws can be detected by weighing. Inspection, and usually one or more boxes are the number of screws required for a fixed number of assembly (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), The number of screws can also be detected by weighing detection (total screw weight/single screw weight = number of screws) to ensure that the supply of screws is sufficient during assembly operations for a fixed number of times to avoid missing and wrong nails.

Further, if the result of the second weighing verification is correct, the first verification module 5 controls the error-proof stapling box to open the cover to perform the cover-opening operation, and takes out the screws from the packaging box and installs them into the erroneous-proof stapling box. . When the screw is loaded into the error-proof staple box, it is considered that the screw reaches the loading station 2.

As the result of the second weighing verification is correct, the screws can be taken out of the box and loaded into the error proof staple box. If the preparatory station 1 is located far away from the error-proof stapler box, the screws or the box may be scattered or dropped during the process of moving the packing box or removing the screws and then moving to the error-proof stapler box. Damage, loss and other phenomena, so the preparatory station 1 can be set on the cover side of the error-proof nailing box. After the cover opening operation is completed, the screws can be directly loaded into the error-proof nailing box from the open cover side. For example, if the cover of the error-proof stapling box is set on the upper side wall of the erroneous stapling box, the preparatory station 1 can also be set on the upper side wall of the error-proof stapling box, that is, the second weighing component and the sweeper. The code component is installed on the upper side wall of the error-proof nailing box, and the packaging box loaded with screws is placed on the preparatory station 1 on the upper side wall of the error-proof nailing box, and the packaging box and screws can be scanned and the second Weighing verification, after verification is correct, unpack the packaging box and pour the screws directly into the error-proof nailing box, so that the screws can reach the loading station 2.

So far, the scan code verification and the second weighing verification have been completed.

In the exemplary embodiment, the loading station 2 is located inside the error-proof stapler box and at the bottom of the box, that is, after the screws are poured into the error-proof stapler box, the screws are regarded as reaching the loading station 2 when they fall into the box bottom. After the screw reaches the loading station 2, the weighing module 6 controls the first weighing component to perform a first weighing verification on the screw. Wherein, the first weighing component can be similarly selected as an electronic weighing device. When the screw reaches the loading station 2, the first weighing component starts to perform weighing detection on the screw.

After the second weighing verification, the main function of re-weighing the first weighing verification is to prevent the screws in a fixed package from not being completely Put it into the error-proof nail box, that is, to avoid the phenomenon of missing or less loading. 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 value of all screws in the packaging box is B, 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 or 1 g above and below is used as the difference range, or the difference range can be preset according to the actual situation, which is not specifically limited. 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, so it is not repeated here.

Further, the loading station 2 is also provided with a regular assembly. When the result of the second weighing verification is correct, the second verification module 7 controls the regular assembly to load the screws on the loading station 2, so that the screws Neatly arranged and loaded in the error-proof staple box. Among them, the regular assembly can be selected as a mechanism with a rotating function, and the screws are arranged in an orderly manner and loaded into the error-proof nailing box by using the rotating centrifugal force.

Through the counting operation, the loading of multiple boxes can be detected, and then the total number of boxes to be packed can be known. The box was scanned. It should be noted that, usually a wrong-proof staple box only carries a single type of screw, that is, the identification code corresponding to the code scanning component of the error-proof staple box is usually unique in the server, that is, it corresponds to a single packaging box and a single type of screws. The number and weight of screws preloaded in the box are also unique.

When the screws of the multi-box packaging box are loaded and inspected, the results of the first weighing verification and the second weighing verification are correlated with the number of statistical operations to verify the results. For example: the weight of a single box is A, and the weight of all screws in a single box is B (excluding the weight of the box); when loading screws in a box, it is necessary to scan the code to verify once, that is, a statistical operation The number of times is 1, the correct result of the first weighing verification should be A+B, and the correct result of the second weighing verification should be B; times, that is, the number of statistical operations is 2, then the correct result of the first weighing verification should be 2(A+B), and the correct result of the second weighing verification should be 2B; When the screw of the box is loaded, it needs to scan the code for n times, that is, the number of statistical operations is n times, then the correct result of the first weighing verification should be n(A+B), and the correct result of the second weighing verification should be is nB.
