Description

  The present invention relates to an assembly support apparatus and an assembly support method that can support an assembly operation of a product even if the position of an article is not specified.

  Conventionally, in the production site of large products such as generators, parts are often manually assembled. The structure of the parts varies from product to product, and drawings must be confirmed each time work is performed, such as confirmation of incoming parts, selection of parts, confirmation of mounting positions of parts, confirmation of weld leg length, and check of finished products. Also, in assembly work by welding, dimensions are read from the drawings, the dimensions are measured in the work area, and punches are put and marked at the mounting positions of the parts. This marking takes time and is a heavy labor that punches hundreds of points. In addition, in the case of an operator who has little experience, there is a possibility that errors in parts and mounting positions may occur.

  In order to improve the efficiency of assembling work and reduce work mistakes, conventionally, apparatuses that support work using spot lights and projectors have been proposed. For example, Patent Document 1 irradiates spot light and instructs the location and work position of a component stored in a predetermined component tray. Thereby, it is possible to work without keeping an eye on the component to be configured. For example, Patent Document 2 proposes an apparatus that uses a projector and projects a drawing corresponding to each stage according to a predetermined work order. As a result, the work can proceed without waiting for an instruction from the work instructor, and the assembly work can be performed without taking out the paper drawing.

  In the figure, an assembly support device supports assembly work for assembling a product. An example in which, for example, a part K1, a part K2, a part K3, and a part K4 are used as a plurality of articles used for assembling the product will be described. For example, the information processing apparatus 2 configured by a personal computer includes a first storage unit 21, a second storage unit 22, and a detection unit 23. In addition, an assembly work area R for assisting assembly of products is set in the assembly support apparatus.

  The assembly work area R in the first embodiment is an area surrounded by reference points R1, R2, R3, and R4, for example, as shown in FIG. These reference points R1, R2, R3, and R4 are preset at, for example, the vertices of a square on a plane of 1000 mm × 1000 mm. The center point of this rectangular assembly work area R is set as the origin of the XY coordinates. Therefore, the reference point R1 is X = + 500, Y = + 500, the reference point R2 is X = + 500, Y = −500, the reference point R3 is X = −500, Y = + 500, and the reference point R4 is X = It can be expressed by coordinates such as −500 and Y = −500. By detecting the positions of these reference points R1, R2, R3, R4, the position in the assembly work area R can be detected.

  The first storage unit 21 stores specific data for specifying a plurality of components K1 to K4. Here, CAD data for specifying the outer shape of each component K1 to K4 is stored as the specific data. The second storage unit 22 stores procedure data in which the positions of the components K1 to K4 are specified for each product assembly procedure and assembly data (“assembly data” described below). ) Is stored.

  For example, when the product is assembled by welding parts, the procedure data includes information on the length of the welding leg at the position where the parts are arranged. In addition to the weld leg length, the procedure data includes other data necessary for product assembly. When a plurality of types of products are set as products, for example, data of product numbers of products is added to the procedure data so that various products can be distinguished.

  When the assembly of the product is completed, for example, it is configured as shown in the perspective view of FIG. 4A, and the cross-sectional view is configured as shown in FIG. Then, when the procedure data of this product is divided and shown as a layer for each procedure, as shown in FIG. 5, it is decomposed from the first procedure to the fourth procedure.

  FIG. 5A shows the arrangement of the part K1 in the first procedure (layer 1 is displayed). Next, FIG. 5B shows the arrangement of the component K2 in the second procedure (in a state where layer 2 is displayed). Next, FIG. 5C shows the arrangement of the component K3 in the third procedure (in a state where the layer 3 is displayed). Next, FIG. 5D shows an arrangement of the component K4 in the fourth procedure (in a state where the layer 4 is displayed).

  Therefore, when all the layers (each procedure data) are overlaid in FIGS. 5A to 5D, as shown in FIG. 3, assembly data (hereinafter referred to as assembly data) in which all parts for assembling the product are arranged. Simply indicated as “assembly data”). In FIGS. 3 and 5, a portion indicated by a double line corresponds to a weld leg length portion. And the detection part 23 uses the specific data (CAD data) stored in the 1st storage part 21 in which position the some components K1-K4 exist in the assembly work area R for assembling a product. Use to detect. A method for detecting the position of the component of the detection unit 23 will be described below.

  The information processing apparatus 2 is connected to the projection unit 3 and the photographing unit 1. The projection unit 3 is formed by a laser projector, for example, and is installed above the assembly work area R. The projection unit 3 projects the procedure data to the assembly position of the product in the assembly work area R and sets the projected procedure data. It has the function as an irradiation part which irradiates light based on the position of the component detected in the detection part 23 with respect to the component currently performed. Further, the projection unit 3 can set an accurate projection position and irradiation position by the reference points R1, R2, R3, and R4.

  The photographing unit 1 is installed above the assembly work area R and photographs an image having position data of the assembly work area R. The image having the position data of the assembly work area R can be obtained by photographing the reference points R1, R2, R3, and R4 described above. Therefore, the position of the component in the detection unit 23 can be detected by collating the image data captured by the imaging unit 1 with the CAD data of the component.

  Further, the assembly support apparatus is provided with a controller 4. The controller 4 can instruct the information processing apparatus 2 wirelessly, and will be described below, such as an operation by an operator to instruct image acquisition of the parts K1 to K4 and the assembled product. It is possible to give an instruction to shift each operation for work support. The controller 4 allows the worker to switch work support at an arbitrary timing according to the individual work speed of the worker without leaving the work position.

  Next, an assembly support method using the assembly support apparatus according to the first embodiment configured as described above will be described with reference to the flowcharts of FIGS. First, a unique product number assigned to each product type for a product to be assembled is input to the detection unit 23 of the information processing apparatus 2 (step S1 in FIG. 7). This input method is determined by a method in which an operator inputs from the controller 4, a method in which the photographing unit 1 reads a product number or the like, and an order set in advance in the manufacturing process. Various methods can be considered, such as a method of inputting a product number.

  And the detection part 23 extracts assembly data as shown in FIG. 3 from the 2nd storage part 22 based on the input product number. And the detection part 23 extracts the specific data (CAD data) of each components K1-K4 used for the said product set to this assembly data from the 1st storage part 21. FIG. Next, the pre-process for assembling the product and the parts K1 to K4 delivered from another factory are arranged in the assembly work area R (step S2 in FIG. 7). At this time, each of the components K1 to K4 may be any as long as it is within the assembly work area R, and may not be arranged in a predetermined order or place.

  Next, the imaging unit 1 acquires an image including the parts K1 to K4 in the assembly work area R (step S3 in FIG. 7). At this time, images of reference points R1 to R4 in the assembly work area R are also acquired. Therefore, the scale and direction of the image of the assembly work area R can be determined on the basis of the images of these reference points R1 to R4, so that an image having position data can be taken. Next, the CAD data (specific data) of the parts K1 to K4 extracted by the detection unit 23 and the image data captured by the photographing unit 1 are collated, and any of the parts K1 to K4 can be collated. Or not (step S4 in FIG. 7).

  Specifically, the image of the assembly work area R is divided into meshes, and the position of the CAD data of the parts is moved for verification. In addition, since the parts K1 to K4 are arranged on the plane of the assembly work area R without specifying the direction, the CAD data of the parts K1 to K4 is collated or the like.

  If any of the parts K1 to K4 can be collated in the assembly work area R, the process proceeds to the next step. If all the parts K1 to K4 cannot be collated in the assembly work area R, an error message “No corresponding part” is displayed on the information processing apparatus 2 (step S20 in FIG. 7), and step S2 is performed again. Returning to step 4, the above-described operation is repeated.

  Next, the detection part 23 performs the detection process which calculates the position in the assembly work area R of the collated components K1-K4 based on the collation result of step S4 (step S5 of FIG. 7). Here, the detection unit 23 calculates the positions of the parts K1 to K4 in XY coordinates based on the reference points R1 to R4 installed in the assembly work area R from the image data having the position data acquired by the photographing unit 1. can do.

  Next, it is determined whether or not all the parts K1 to K4 used for assembling the product are aligned (attached) in the assembly work area R (step S6 in FIG. 7). Then, if it is determined that all the parts K1 to K4 are already attached (YES), the process proceeds to the next step. Further, if any one of all the parts K1 to K4 has not been inserted, the process returns to step S2 and is described above until position data (coordinate data) of all the parts K1 to K4 is detected. Repeat the operation.

  Next, assembly work is started according to the product assembly procedure. First, first procedure data, here, procedure data for the first procedure shown in FIG. 5A is read from the second storage unit 22 (step S7 in FIG. 7). Next, the projection unit 3 irradiates the position (coordinate data) of the component K1 set in the procedure data. The position has been detected in the previous step S5. And the irradiation process in which light is irradiated to the component K1 existing at the position is performed (step S8 in FIG. 7).

  As a result, the part K1 necessary for the procedure for assembling the product and the position thereof are provided to the operator by visual information. Therefore, the part K1 can be selected without referring to the drawings for assembling the product. Further, it is possible to save time to search for the corresponding part K1 by expanding the drawing and confirming the shape and dimensions of the part K1. Further, it is possible to prevent selection mistake of the component K1.

  Next, the projection unit 3 performs a projection process in which the procedure data is projected onto the assembly position of the product in the assembly work area R (step S9 in FIG. 8). Specifically, the procedure data is projected as shown in FIG. Thereby, it is possible to grasp the mounting position of the component K1 and the dimensions of the mounting surface without looking at the drawing. Further, by simply aligning the part K1 with the irradiation position of the procedure data, the mounting position and dimensions of the part K1 can be arranged without making a mistake, and work errors can be reduced. Here, if the projection location which irradiates the procedure data is an assembly location where the product is assembled, any of the floor surface, the surface plate, the work table, etc. in the assembly work area R may be used. The part K1 that is the basis of assembly may be directly projected onto the part K1 as the assembly part of the product.

  Next, the component K1 is placed at an appropriate position according to the projected procedure data (step S10 in FIG. 8). Next, a part welding process is performed. However, since the part K1 is not a part to be welded, this step (step S11) and the next step (step S12) are skipped.

  Next, an image of the product is acquired by the photographing unit 1 (step S13 in FIG. 8). Next, the assembly data and the acquired image data are collated (step S14 in FIG. 8). Next, it is determined from the collation result whether or not the attachment of all the parts K1 to K4 is completed (step S15 in FIG. 8). If it is determined that all the parts K1 to K4 have not been attached yet (NO), the process returns to step S7, and the above operation is repeated from the next procedure data. If it is determined that all the parts K1 to K4 are attached (YES), the assembly of the product is finished.

  Here, since only the component K1 is assembled, the process returns to step S7, and the same operation as described above is performed. Here, the procedure data of the second procedure shown in FIG. 5B is read from the second storage unit 22 (step S7 in FIG. 7). Next, the projection unit 3 emits light to the position (coordinate data) of the component K2 set in the procedure data, and the component K2 is irradiated with light (step S8 in FIG. 7). Next, the projection unit 3 performs a projection process in which the procedure data is projected onto the assembly position of the product in the assembly work area R (step S9 in FIG. 8). Specifically, as shown in FIG. 6B, the procedure data is projected so as to overlap the part K1.

  Next, the component K2 is placed at an appropriate position according to the projected procedure data (step S10 in FIG. 8). Next, the part K2 is welded (step S11 in FIG. 8). Next, it is visually confirmed whether or not the weld leg length of the welding performed is in accordance with the projected procedure data (step S12 in FIG. 8). If it is as indicated in the procedure data (YES), the process proceeds to the next step. If it is not as indicated in the procedure data, the process returns to step S11 to repeat the above-described operation.

  At this time, since the projected procedure data is projected as an image with the same welding leg length, the welding leg length can be easily confirmed, and it is not necessary to measure the welding leg length with a gauge or the like, and the welding process (step S11). It can be performed. Further, at this time, it is possible to confirm whether or not the weld leg length as instructed is ensured by comparing with the position of the weld leg length in the irradiated procedure data without measuring with a gauge or a scale (step S12).

  Thereafter, the above-described steps are repeated. Therefore, in the next procedure, the procedure data of the third procedure shown in FIG. 5C is read. Then, light is irradiated to the position of the component K3 set in the procedure data, and the procedure data is projected so as to overlap the component K1 and the component K2, as shown in FIG. Further, in the next procedure, the procedure data of the fourth procedure shown in FIG. Then, light is irradiated to the position of the component K4 set in the procedure data, and the procedure data is projected so as to overlap the components K1 to K3 as shown in FIG. A product is assembled by repeating such an operation.

  It should be noted that the movement of each operation can be appropriately operated by the operator according to the work situation by the controller 4, or can be automatically set in advance by the information processing apparatus 2, and in any case May be used. Since this is the same in the following embodiments, the description thereof will be omitted as appropriate.

  According to the assembly support device of the first embodiment configured as described above, it is possible to detect the position of an article even if the articles used for assembling the product are not arranged in a predetermined position and order. . In addition, the procedure data is projected, and the article whose position is detected can be irradiated with light, so that assembly work can be performed.Therefore, without referring to the drawings each time, the installation procedure, the mounting position, the dimensions of the component parts, Assembly work can be performed without making a mistake in the weld leg length.

  Moreover, since it has the information of the welding leg length in that case, it can carry out without confirming the leg length instruction | indication of an applicable part, and the time which takes out drawing and searches an applicable location can be shortened. In addition, since the assembled product can be checked against the procedure data, even an inexperienced worker can use a special gauge to check whether the leg length is in accordance with the instructions after welding. The product can be assembled accurately without the need to do so.

  In the first embodiment, an example in which the projection process for projecting the procedure data is performed after the irradiation process for irradiating the component with light is shown. However, the present invention is not limited thereto, and the projection process for projecting the procedure data is performed. After that, an effect similar to that of the first embodiment can be obtained by performing an irradiation step of irradiating the component with light.

  In the first embodiment, the example of the parts K1 to K4 has been described. However, the present invention is not limited to this, and other parts can be similarly implemented. Also, if the number of parts is too large to fit in the assembly work area, if the work becomes complicated, or if it becomes difficult to identify the parts, multiple sets of parts are required. It is possible to divide into two groups and set to assemble each group. In that case, the assembly support method of the first embodiment may be repeated for each set.

  In the first embodiment, only the “parts” that are part of the finished product are shown as examples of the articles used to assemble the product. However, the present invention is not limited to this. For example, As an article used for assembling a product, a tool or the like can be set and dealt with. Therefore, as in the first embodiment, it is possible to have the tool specific data, thereby grasping the position of the tool, and to deal with the same as in the first embodiment. It is effective when using.

  In the first embodiment, an example is shown in which an image is taken from above the assembly work area by the photographing unit. However, the present invention is not limited to this, and an image is taken from the side of the assembly work area. Further, it is possible to determine these by combining the image from the upper side and the image from the side surface direction. In that case, it is possible to specify the article three-dimensionally, and it is possible to reliably specify the article.

  In the first embodiment, the example in which the assembly work of the product is performed after confirming that all the parts used in the product are present in the assembly work area has been described. However, the present invention is not limited to this. Then, it is determined whether or not only parts necessary for the procedure data to be actually performed exist in the assembly work area, and only the position of the parts is detected, and the product assembly support is performed as in the first embodiment. May be performed.

  Moreover, in the said Embodiment 1, although the case where a product was assembled by welding process was demonstrated, it is not restricted to this, When it assembles a product by another process, it can carry out similarly, There is an effect.

  In the first embodiment, the photographing unit may have any function for imaging the shape of each component and the assembled product, and may be configured by, for example, a thermal imaging apparatus.

In the second embodiment, ID information tags 51 to 54 storing ID data of the components K1 to K4 are attached to the components K1 to K4, respectively. The ID information tags 51 to 54 have a wireless communication function, and can be formed by, for example, an RF tag. And the specific data of each components K1-K4 becomes ID data of each components K1-K4. Therefore, the first storage unit 21 stores ID data of the components K1 to K4.

  And the receiver 7 for acquiring the ID data of these ID information tags 51 to 54 is divided into a grid in the assembly work area R as shown in FIG. Then, the receiver 7 transmits the ID data to the information processing device 2. And the detection part 23 detects the position of each components K1-K4 based on the position of the receiver 7 from which this ID data was detected. In the second embodiment, an example in which a plurality of receivers 7 are provided has been described. However, the present invention is not limited to this, and if the ID information tags 51 to 54 are formed by a GPS transmitter, the information processing apparatus. It is also possible to receive the ID data at 2 and detect the position. In detecting the positions of the components K1 to K4, the positions can be detected with higher accuracy by detecting the positions of the reference points R1 to R4 and comparing them.

  Next, an assembly support method using the assembly support apparatus according to the second embodiment configured as described above will be described with reference to the flowcharts of FIGS. First, as in the first embodiment, the product number of the product is input to the detection unit 23 of the information processing apparatus 2 (step S1 in FIG. 11). Next, the parts K1 to K4 are arranged in the assembly work area R (step S2 in FIG. 11). Next, the detection unit 23 extracts assembly data from the second storage unit 22 as shown in FIG. 3 based on the input product number. And the detection part 23 extracts the specific data of each components K1-K4 used for the said product set to this assembly data from the 1st storage part 21 (step S33 of FIG. 11). At this time, the specific data of the components K1 to K4 is ID data.

  Next, each receiver 7 acquires the ID data of the ID information tags 51 to 54 of the parts K1 to K4 in the assembly work area R (step S34 in FIG. 11). Next, a detection step of detecting the position of each component K1 to K4 is performed based on the ID data of each component K1 to K4 extracted by the detection unit 23 and the position of each receiver 7 that acquired the ID data ( Step S35 in FIG. 11).

Then, if it is determined that all the parts K1 to K4 are already attached (YES), the process proceeds to the next step. Further, if any one of all the parts K1 to K4 has not been inserted, the process returns to step S2 and is described above until position data (coordinate data) of all the parts K1 to K4 is detected. Repeat the operation.

  Next, according to the product assembling procedure, as in the first embodiment, the assembling work starts, and steps S7 to S12 are performed. Then, it is determined whether or not all the components K1 to K4 have been attached (step S36 in FIG. 12). In the second embodiment, whether or not the attachment is completed is determined based on whether or not the procedure data has reached the last procedure.

  In the second embodiment, the example in which the specific data in which the parts K1 to K4 and the ID data are associated with each other is stored in the first storage unit 21 in advance is shown. However, the present invention is not limited to this.
