Description

[Technical Field]

[0001] The present invention relates to a work assistance device. [Background technology]

[0002] Patent Document 1 listed below discloses a wearable communication terminal, which is an example of a conventional work support device. This wearable communication terminal is equipped with a monitor unit for displaying work procedure information, and is configured to display the (N+1)th work procedure information on the monitor unit when a worker issues an Nth completion information call.

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-114111 Summary of the Invention [Problem to be solved by the invention]

[0004] The wearable communication terminal has the advantage that by providing workers with the correct work procedures, they can perform the work without having to memorize them. However, even if the correct work procedures are provided to workers, the workers may not actually perform the work according to those procedures, and there may be cases where the actual work content differs from the standard work due to human error or the like. Therefore, simply providing workers with the correct work procedures is not enough to provide work support measures.

[0005] The present invention has been made in view of the above-mentioned problems, and aims to provide a work assistance device that can perform work assistance with high accuracy. [Means for solving the problem]

[0006] One aspect of the present invention is an information display unit that displays information about the standard work; a detection unit capable of detecting a state change of a trigger parameter occurring during the standard work; a camera that photographs an area where a task is performed in a task step when the detection unit detects a change in the state of the trigger parameter; a determination unit that determines whether the work step corresponds to the work step performed in the work execution area by comparing the image captured by the camera with a standard image corresponding to the standard work; A work support device comprising: is located. [Effects of the Invention]

[0007] The work assistance device of the above aspect is characterized by having a function of displaying information about standard work on the information display unit and, in addition, determining whether the work steps that the worker would have actually performed correspond to the standard work based on this information. To this end, the work assistance device is configured to, upon the condition that the detection unit detects a change in the state of a trigger parameter that occurs during standard work, capture an image of the work area where the actual work step is performed with a camera and compare the captured image with a standard image corresponding to the standard work. This configuration not only provides the worker with correct information about standard work, but also enables highly accurate work assistance measures that go as far as determining whether the worker correctly performed the work steps of the standard work. This makes it possible to prevent human error during actual work.

[0008] As described above, according to the above-described aspect, it is possible to provide a work assistance device that can perform work assistance with high accuracy. [Brief explanation of the drawings]

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of a work support device according to the present invention will be described below with reference to the drawings.

[0026] (Embodiment 1) 1. Configuration of the work support device 101 As shown in Fig. 1, the work assistance device 101 of the first embodiment is a device for work assistance (assisting a worker), and includes glasses 10 and an external server 30. The glasses 10 are glasses-type wearable devices that are worn on the head of a worker (see "Worker U" in Fig. 2), and include a frame unit 11 and a pair of left and right lens units 12. The glasses 10 are also generally referred to as "AR (Augmented Reality) glasses" or "smart glasses."

[0027] The frame unit 11 is provided with a detection unit 14, a camera 15, input units 16 and 17, and a control unit 20. An information display unit 13 is also provided in a part of the lens unit 12 on the right side as viewed from the worker U (see FIG. 2). If necessary, the information display unit 13 may be provided only on the lens unit 12 on the left side as viewed from the worker U, or on both of the pair of left and right lens units 12.

[0028] The detection unit 14 is configured to be able to detect state changes of trigger parameters that occur during standard work. As shown in FIG. 3, the "trigger parameter" here corresponds to one or more trigger parameters T pre-selected from, for example, heat, light, magnetic field, sound, acceleration, pressure (applied pressure), shape recognition, etc. Preferably, the detection unit 14 is an AI (artificial intelligence) that has been trained using deep learning or machine learning to learn the "reference state" of the trigger parameter T and a "detected state" that deviates from this reference state. This makes it possible to accurately detect when the state of the trigger parameter T changes from the reference state to the detected state. The number of detection units 14 is not particularly limited and can be set appropriately depending on the number of selected trigger parameters T.

[0029] Camera 15 is an imaging means for imaging work areas A1 to An where workers U actually perform work, on condition that detection unit 14 detects that a change in the state of trigger parameter T has occurred in the work areas A1 to An (i.e., that the state of trigger parameter T has changed from the reference state to the detected state). For this purpose, camera 15 is configured to ensure a field of view C that covers work areas A1 to An.

[0030] The input units 16 and 17 are physical input switches that allow the worker U to input an evaluation result Rb of the implementation state of the work step. In this embodiment, an OK evaluation is input by operating the input unit 16, and an NG evaluation is input by operating the input unit 17. Instead of being physical input switches as in this embodiment, the input units 16 and 17 may be operated on the information display unit 13 or another screen. Note that, because the evaluation result Rb is obtained by visual inspection, it is preferable that the worker U who inputs the evaluation result Rb be an experienced worker.

[0031] The information display unit 13 is configured to display information W about the standard work superimposed on the view that the worker U actually sees through the lens unit 12. This allows the worker U to view the information W displayed on the information display unit 13 while maintaining a field of view B of the work areas A1 to An through the lens unit 12 of the glasses 10.

[0032] 2. Configuration of the control unit 20 As shown in FIG. 1, the control unit 20 includes a transmission / reception unit 21, a storage unit 22, an image processing unit 23, a determination unit 24, and an evaluation unit 25. The control unit 20 is connected to an external server 30 via a communication network (not shown) to enable bidirectional communication. The control unit 20 is equipped with an AI program P that uses AI. The transmission / reception unit 21 has a function of transmitting and receiving various types of information. The transmission / reception unit 21 receives multiple pieces of information from the external server 30, including information W, a standard image Ib corresponding to the standard work, and an AI program P for comparison. The transmission / reception unit 21 also transmits information stored in the storage unit 22 to the external server 30 as needed. The storage unit 22 has a function of readably storing various pieces of information. The storage unit 22 stores multiple pieces of information, including the information W, the standard image Ib, and the AI ​​program P acquired from the external server 30, and the evaluation results Rb input from the input units 16 and 17. The AI ​​program P may be updated as appropriate.

[0033] The image processing unit 23 has a function of processing information acquired by image capture by the camera 15 to generate a captured image Ia. The determination unit 24 has a determination function of comparing the captured image Ia acquired by the camera 15 with a standard image Ib acquired from the external server 30 in accordance with the AI ​​program P, thereby determining whether or not the work steps (work steps S1 to Sn described below) performed in the work areas A1 to An correspond to the standard work. The evaluation unit 25 has an evaluation function of evaluating the determination result Ra by the determination unit 24 based on the evaluation result Rb input by the input units 16 and 17. In this embodiment, the determination function by the determination unit 24 and the evaluation function by the evaluation unit 25 are both executed by AI installed in the control unit 20.

[0034] 3. Configuration of external server 30 As shown in FIG. 1, the external server 30 is a cloud or a data server, and includes a transmission / reception unit 31, a storage unit 32, and a generation unit 33. The transmission / reception unit 31 has a function of transmitting and receiving information to and from the transmission / reception unit 21 of the control unit 20. The storage unit 32 has a function of storing a large number of captured images Ia and standard images Ib in advance, and also has a function of storing an AI program P generated by the generation unit 33. The generation unit 33 has a function of generating the AI ​​program P by machine learning (AI learning) based on the captured images Ia and standard images Ib. Note that, if necessary, this generation unit 33 may be provided in the control unit 20 of the glasses 10.

[0035] The functions of the above-mentioned components constituting each of the control unit 20 and the external server 30 are executed by a processor. The term "processor" as used here broadly encompasses, among the components of a computer, processing devices that perform operations such as data calculations and conversions, program execution, and control of other devices. The processor may be constructed from all or part of a CPU (Central Processing Unit) that controls the entire computer, an MPU (Micro Processing Unit) that integrates some of the functions of a CPU, or an NPU (Neural Network Processing Unit) that mainly performs AI processing.

[0036] 4. Information about standard work Here, with reference to FIGS. 4 to 9, an example of information W displayed on the information display unit 13 when work is being performed in the automobile manufacturing process will be described.

[0037] 4-1. Spot welding work W1 Information W shown in FIG. 4 is information related to spot welding operation W1, which is an example of standard work. Although not specifically shown, spot welding operation W1 is a known work in which a worker manually performs spot welding using a manual spot welder. In this spot welding operation W1, it is necessary to spot weld each of a plurality of predetermined locations on the vehicle body in the correct order without omission. Therefore, information display unit 13 displays the order of a plurality of work areas A1 to An and a plurality of work steps S1 to Sn involved in this spot welding operation W1.

[0038] Here, the first (1st) work area is "A1", the second work area is "A2", and the nth work area is "An". Also, the first (1st) work step is "S1", the second work step is "S2", and the nth work step is "Sn".

[0039] This allows the worker U to perform the actual spot welding work W1 while wearing the glasses 10 and visually checking the position and order of each work step. During the spot welding work W1, changes in the state of parameters such as heat, light, and magnetic field may occur compared to before the work started. In other words, it is expected that the state of these parameters will change significantly before and after the spot welding work W1 is performed. Therefore, it is sufficient to set at least one of these parameters as a trigger parameter T and use a detection unit 14 that can detect a change in the state of the trigger parameter T. For example, the number of detection units 14 can be set to match the number of trigger parameters T.

[0040] 4-2. Weld nut welding work W2 Information W shown in FIG. 5 is information about a weld nut welding operation W2, an example of a standard operation. Although not specifically illustrated, the weld nut welding operation W2 is a known operation in which a worker welds a weld nut to a vehicle body using a dedicated welding machine. This weld nut welding operation W2 requires positioning weld nuts at multiple predetermined locations on the vehicle body and welding them one by one in order without omission. Therefore, information display unit 13 displays the multiple work areas A1-An and the order of the multiple work steps S1-Sn involved in this weld nut welding operation W2. This allows worker U, wearing eye glasses 10, to perform the actual work while visually checking the position and order of each work step in the weld nut welding operation W2. In this weld nut welding operation W2, as with spot welding operation W1, at least one of the heat, light, and magnetic field parameters is set as a trigger parameter T, and detection unit 14 is used to detect changes in the state of the trigger parameter T.

[0041] 4-3. Chisel check work W3 Information W shown in FIG. 6 is information related to a chisel check task W3, an example of standard work. Although not specifically illustrated, the chisel check task W3 is a known task in which a worker directly drives a tool called a "chisel" into gaps in joints formed between steel plates of a vehicle body by welding work such as spot welding, and checks the condition of the joints by checking the quality of the welds. This chisel check task W3 requires a thorough inspection of multiple predetermined joints on the vehicle body, one by one, in order. Therefore, the information display unit 13 displays multiple work areas A1-An and the order of multiple work steps S1-Sn involved in this chisel check task W3. This allows the worker U, wearing the eye protection glasses 10, to perform the actual work while visually checking the position and order of each work step in the chisel check task W3. During this chisel check task W3, changes in the state of parameters such as sound, acceleration, and pressure may occur compared to before the task began. In other words, it is expected that the state of these parameters will change significantly before and after the chisel check task W3. Therefore, it is sufficient to set at least one of these parameters as the trigger parameter T and use the detection unit 14 that can detect a change in the state of the trigger parameter T.

[0042] 4-4. Bolt tightening work W4 Information W shown in FIG. 7 is information related to a bolt tightening operation W4, an example of a standard operation. Although not specifically illustrated, the bolt tightening operation W4 is a known operation in which a worker uses fastening bolts to fasten steel plates of a vehicle body. This bolt tightening operation W4 requires that predetermined locations on the vehicle body be tightened one by one in a sequential order without omission. Therefore, the information display unit 13 displays the multiple work areas A1 to An and the order of the multiple work steps S1 to Sn involved in this bolt tightening operation W4. This allows the worker U, wearing the glasses 10, to perform the actual work while visually checking the position and order of each work step in the bolt tightening operation W4. In this bolt tightening operation W4, as with the chisel check operation W3, at least one of parameters such as sound, acceleration, and pressure can be set as a trigger parameter T, and a detection unit 14 capable of detecting a change in the state of the trigger parameter T can be used.

[0043] 4-5. Sealer application work W5 Information W shown in FIG. 8 is information regarding a sealer application job W5, an example of a standard job. Although not specifically illustrated, the sealer application job W5 is a known job in which a worker applies a material called "sealer" to the joints of steel plates of a car body using a special tool to waterproof, rust-proof, and soundproof the joints. This sealer application job W5 requires that the sealer be applied to multiple predetermined locations on the car body, one by one, in a sequential order. Therefore, the information display unit 13 displays the multiple work areas A1-An and the order of the multiple work steps S1-Sn involved in this sealer application job W5. This allows the worker U, wearing the glasses 10, to perform the actual work while visually checking the position and order of each work step in the sealer application job W5. During this sealer application job W5, changes in the state of parameters such as sound and pressure may occur compared to before the job began. In other words, it is expected that the state of these parameters will change significantly before and after the sealer application job W5 is performed. Therefore, it is sufficient to set at least one of these parameters as the trigger parameter T and use the detection unit 14 that can detect a change in the state of the trigger parameter T.

[0044] 4-6. Parts setting work W6 The information W shown in FIG. 9 is information about a part setting operation W6, an example of a standard operation. Although not specifically illustrated, the part setting operation W6 is a known operation in which parts are set on a vehicle body using a robot. This part setting operation W6 requires that parts be set one by one in order at multiple predetermined locations on the vehicle body without any omissions. Therefore, the information display unit 13 displays the multiple operation areas A1-An and the order of the multiple operation steps S1-Sn involved in this part setting operation W6. This allows the worker U, wearing the glasses 10, to perform the actual operation while visually checking the position and order of each operation step in the part setting operation W6. During this part setting operation W6, changes in the status of parameters such as sound and shape recognition may occur compared to before the operation began. In other words, it is expected that the status of these parameters will change significantly before and after the part setting operation W6. Therefore, at least one of these parameters may be set as a trigger parameter T, and a detection unit 14 capable of detecting the change in the status of the trigger parameter T may be used.

[0045] 5. Work support method Next, a work support method using the work support device 101 configured as described above will be described.

[0046] The work assistance method of this embodiment is executed sequentially according to a plurality of steps from step S101 to step S114 in the flowchart shown in Fig. 10. Note that one or more steps may be added to these steps as needed, or multiple steps may be appropriately integrated. These steps are executed by the control unit 20 or the worker U as appropriate.

[0047] Step S101 is a step for detecting the selection of a scheduled standard work. This step S101 detects the selection information of the standard work input by the worker U using an input means (not shown) such as a physical switch. The process in step S101 may be, for example, a process for selecting and confirming an arbitrary standard work from among a plurality of standard works displayed on the display unit, or a process for confirming the execution of one standard work displayed on the display unit.

[0048] Step S102 is a step for displaying information W about the standard work whose selection was detected in step S101. In step S102, the information W is displayed on the information display unit 13. For example, if spot welding work W1 is the standard work, the order of work execution areas A1 to An and work steps S1 to Sn for the spot welding work W1 is displayed on the information display unit 13 (see FIG. 4). Step S102 has the effect of eliminating the need for the worker U to memorize the positions and orders of multiple standard works, and of eliminating the need for accessories such as instruction manuals, actual samples, and jigs. Another effect is that it reduces the time required for the worker U to become accustomed to the work.

[0049] Step S103 is a step in which a task step of the standard task is started or performed. Step S104 is a step following step S103 in which the detection unit 14 determines whether or not a state change in the trigger parameter T has been detected (i.e., the state of the trigger parameter T has changed from the reference state to the detected state). In step S104, for example, if the detection unit 14 detects that the value of the trigger parameter T has changed from the reference value to a value within a predetermined range, it can be determined that a state change in the trigger parameter T has been detected. Step S105 is a step in which the camera 15 photographs the task execution area on the condition that the detection unit 14 detected a state change in the trigger parameter T in step S104. In step S105, if the first task step S1 has been started in step S103, the camera 15 photographs the first task execution area A1 corresponding to the task step S1. Furthermore, if the second task step S2 has been performed in step S103, the camera 15 photographs the second task execution area A2 corresponding to the task step S2. Similarly, when the n-th work step Sn is performed in step S103, the camera 15 captures an image of the n-th work execution area An corresponding to the work step Sn.

[0050] Step S106 compares the captured image Ia obtained in step S105 with a standard image Ib corresponding to the standard work to determine whether the work step started or performed in step S103 corresponds to the standard work. In step S106, the captured image Ia is compared with the standard image Ib and evaluated according to an AI program P pre-installed in the control unit 20 (see FIG. 1). Step S106 automatically determines whether the captured image Ia corresponds to the standard image Ib (i.e., whether the work steps corresponding to the captured image Ia were performed in the correct order and at the correct positions according to the standard work). Step S106 has the advantage of eliminating the need to access the external server 30 or perform machine learning each time. Note that, if necessary, it may be possible to determine only whether the work steps were performed in the correct order according to the standard work, or whether the work steps were performed at the correct positions according to the standard work. The determination result Ra in step S106 is stored in the memory unit 22 (see FIG. 1) in step S107.

[0051] In step S106, for example, based on the captured image Ia of the first work area A1, it is determined whether the content of the work step S1 actually performed in that work area A1 is correct and in line with standard work. Also, based on the captured image Ia of the second work area A2, it is determined whether the content of the work step S2 actually performed in that work area A2 is correct and in line with standard work. Similarly, based on the captured image Ia of the nth work area An, it is determined whether the content of the work step Sn actually performed in that work area An is correct and in line with standard work.

[0052] Step S108 is a step for determining whether or not the judgment result Ra in step S106 is an "OK judgment." According to this step S108, if the judgment result Ra is an "OK judgment" (in the case of "Yes"), the process proceeds to step S109, and if not (in the case of "No"), that is, if the judgment result Ra is an "NG judgment," the process proceeds to step S110. Then, in step S109, the "OK judgment" is displayed on the information display unit 13, and in step S110, the "NG judgment" is displayed on the information display unit 13.

[0053] Step S111 is a step for determining whether or not there is an instruction for the next work step. If "Yes" in step S111, the process proceeds to step S112, and if "No" in step S111, the process returns to step S103.

[0054] Step S112 is a step for determining whether or not the operator has input the evaluation result Rb from the input unit 16, 17 (see FIG. 1). According to this step S112, if the evaluation result Rb has been input (in the case of "Yes"), the process proceeds to step S113, and if not (in the case of "No"), that is, if the evaluation result Rb has not been input, the process ends. The evaluation result Rb is stored in the storage unit 22 (see FIG. 1) in step S113.

[0055] Step S114, following step S113, is a step in which the judgment result Ra obtained in step S106 is evaluated based on the evaluation result Rb input in step S112. According to step S114, by comparing the judgment result Ra with the evaluation result Rb finally obtained by visual confirmation by the operator U, it is possible to evaluate whether the judgment result Ra is correct. For example, if the judgment result Ra is an "OK judgment" and the evaluation result Rb is an "OK evaluation," or if the judgment result Ra is an "NG judgment" and the evaluation result Rb is an "NG evaluation," the judgment result Ra is evaluated as correct. On the other hand, if the judgment result Ra is an "OK judgment" but the evaluation result Rb is an "NG evaluation," or if the judgment result Ra is an "NG judgment" but the evaluation result Rb is an "OK evaluation," the judgment result Ra is evaluated as incorrect. Note that in step S112, it is preferable to use machine learning (AI learning) using a large amount of data accumulated by linking the judgment results Ra and the evaluation results Rb. This makes it possible to improve the accuracy of the determination result Ra.

[0056] 6. Action and Effects According to the above-described first embodiment, the following effects can be obtained.

[0057] The work support device 101 of the first embodiment is characterized by displaying information W about standard work on the information display unit 13 of the glasses 10 and by having a function to determine whether the work steps S1 to Sn that the worker U would have actually performed correspond to the standard work based on this information W. To achieve this, the work support device 101 is configured to capture the work areas A1 to An of the actual work steps S1 to Sn using the camera 15 when the detection unit 14 detects a state change in the trigger parameter T that occurs during standard work, and to compare the captured image Ia obtained by the capture with the standard image Ib corresponding to the standard work. This configuration not only provides the worker U with correct information W about standard work, but also enables highly accurate work support measures that go as far as determining whether the worker U correctly performed the work steps S1 to Sn of the standard work. This makes it possible to prevent human error during actual work.

[0058] Therefore, according to the first embodiment, it is possible to provide a work assistance device 101 that can perform work assistance with high accuracy.

[0059] According to the work support device 101, the information display unit 13, the detection unit 14, the camera 15, and the judgment unit 24 can all be provided in the glasses 10 worn by the worker U. In particular, the detection unit 14 and the camera 15 can be provided in the frame unit 11 of the glasses 10, the information display unit 13 can be provided in the lens unit 12 of the glasses 10, and the judgment unit 24 can be provided in the control unit 20 of the glasses 10. When the judgment unit 24 is provided in the control unit 20 of the glasses 10, the glasses 10 themselves can perform the process of determining whether or not the work steps S1 to Sn correspond to standard work.

[0060] According to the work support device 101, the information display unit 13 that displays the information W about the standard work can also be used as a display unit that displays the determination result by the determination unit 24.

[0061] Hereinafter, other embodiments related to the above-described embodiment 1 will be described with reference to the drawings. In the other embodiments, the same elements as those in embodiment 1 are denoted by the same reference numerals, and the description of the same elements will be omitted.

[0062] (Embodiment 2) 11 , the work support device 102 of the second embodiment differs from the work support device 101 of the first embodiment in the configuration of the control unit 20 of the glasses 10 and the configuration of the external server 30. The work support device 102 is configured so that the components of the control unit 20, excluding the transmission / reception unit 21, are provided in the external server 30.
