Description

  The present invention relates to an assembly work apparatus that manages assembly work of electronic equipment or the like in a production factory or the like.

  2. Description of the Related Art A work method is known in which one worker takes charge of all assembly work steps using a single production work table in an assembly work of electronic equipment or the like in a production factory or the like. In this work method, each worker takes out a necessary part from a parts storage place and performs a predetermined assembling work while referring to a work procedure manual corresponding to the progress of each assembling process.

  Also, in this assembly work method, a plurality of workers use the work tables for each person to assemble the same or different electronic devices or the like.

  However, the above-described assembly method has the following problems.

  (1) Each worker needs to be proficient in grasping the entire work process, and must take out a work procedure manual for each process or learn the arrangement of parts to be worked.

  (2) Since there are many parts that depend on the attention and memory of the worker, there is a possibility that an error due to the carelessness of the worker may occur. In addition, there is a limit to expressing the work instruction content in the text of the work procedure manual.

  (3) A large amount of paper media is required for work instructions, quality records during work, or work procedure manuals.

  (4) It is difficult to grasp the work time for each worker and each work process.

  The present invention has been made in view of such a conventional problem, and does not depend on the proficiency level or attention of the operator, and can indicate the work procedure by means other than letters and drawings. An object of the present invention is to provide an assembling apparatus capable of analyzing the situation.

  In order to solve the above-mentioned problem, in the assembly work apparatus according to claim 1 of the present invention, a series of work is performed by using a production work table assigned to a single worker by a single worker in a production factory or the like. In the work system responsible for the assembly work, a work procedure display means for displaying the work procedure for each work process on the display device, a work execution detection means for detecting that each work process has been performed, and the work execution detection means And a next process display means for changing the display on the display device to the work procedure of the next work process when it is detected that the work process has been performed.

  That is, when the worker starts assembly work, work procedures such as parts to be used, attachment locations, and attachment methods are displayed on the display device according to the work order. Then, it is detected that each work process has been performed, and at this time, the display on the display device is changed to the work procedure of the next work process.

  For this reason, the operator does not need to memorize | store the whole work process, arrangement | positioning of components, etc. At this time, the work instruction content displayed on the display device can use not only characters and monochrome images but also color images, moving images, sounds, and the like as necessary.

  In addition, since the work instruction can be created as an electronic document, it does not occupy a part of the workbench and does not deteriorate due to repeated use, as compared with the case where a paper medium is used. Furthermore, it is possible to flexibly cope with creation and modification of work instructions, and it is possible to combine contents that cannot be handled by paper media such as voice and moving images.

  And since it can detect that each work process was implemented, the work time required in each work process can be automatically recorded and totaled.

  According to another aspect of the assembly work apparatus of the present invention, a plurality of parts boxes are provided for each type of parts used in a series of assembly work, and each part box is provided with an indicator lamp and parts in the parts box. And a sensor for detecting that the part has been taken out, and an indicator lamp lighting means for lighting the indicator lamp of the parts box in which a part used in the next work process is stored. When it is detected by the sensor provided in the component box that the component box instructed is taken out by turning on the instruction lamp, it is determined that the previous work process has been performed.

  That is, in a series of assembly operations, a display lamp indicating that the component is the next component to be used is turned on in the component box provided on the component storage shelf or the like. The sensor detects that a part has been removed from the parts box. As a result, mistakes in parts can be prevented, and for example, when a part in an unspecified parts box is taken out, the mistake is displayed on the display device, and the next work instruction is not displayed. It is possible to prevent mistakes.

  And since a sensor is provided to detect that a part has been removed from the parts box, the work time required for the worker to install each part is automatically recorded by recording the sensor sensing time. And can be aggregated. In addition, information at the time of work can be registered as a quality record according to the screen display of the display device.

  As described above, in the assembly work device according to the first aspect of the present invention, even if the operator is not familiar with the order of the assembly work, he follows the guidance on the screen display of the display device installed on the work table or the like. A series of assembly operations can be performed simply by performing the operations.

  Therefore, the work procedure can be shown by means other than letters and drawings without depending on the skill level and attention of the worker, and the assembly work device can analyze the work situation such as work time.

  Further, in the assembly work apparatus according to the second aspect, in a series of assembly work, it is possible to reliably prevent an erroneous attachment of the component by simply attaching the component taken out from the component box whose indicator lamp is lit.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing an assembly work apparatus 1 according to the present embodiment. The assembly work apparatus 1 is used in a work system in which a single worker is responsible for a series of assembly work in a production factory or the like. ing.

  The assembly work apparatus 1 includes a production worktable 11 and a parts shelf 12 assigned to a single worker, and a series of assembly work is performed using the worktable 11 and the parts shelf 12. Configured to do. Note that the number of the component shelves 12 may be further increased as necessary, or may not be used if not necessary.

  The work table 11 is provided with a personal computer 21 that controls processing of work instructions, a display device 22 that includes a liquid crystal panel that displays work instruction contents, and a keyboard 23 and a mouse 24 that input data to the personal computer 21. A plurality of component boxes 25,... Are provided on the left side. A plurality of parts boxes 26,... Are also provided on the parts shelf 12 arranged on the side of the work table 11.

  As shown in FIG. 2 showing the details of the component box 25, each component box 25, 26,... Contains each component 31,. The product is assembled by assembling the parts 31. The right side wall 32 of each component box 25, 26,... Is provided with indicator lamps 33, 43 (see FIG. 3) made of LEDs indicating that the component 31 is used in the work process. The lamps 33 and 43 are connected to the personal computer 21. In addition, on the outer surface of the left side wall 35 of each component box 25, 26,..., For example, an ultrasonic type or electrostatic capacitance type extraction sensor that detects that a hand has been inserted into the component box 25, 26. 36 and 46 (see FIG. 3) are provided, and the take-out sensors 36 and 46 are also connected to the personal computer 21. Thus, the personal computer 21 can detect that the part 31 in the parts box 25, 26 has been taken out by detecting the hand inserted at the time of taking out the part 31 with the take-out sensors 36, 46. Has been.

  FIG. 3 is a block diagram showing the assembly work apparatus 1, and the assembly work apparatus 1 is configured around the personal computer 21.

  The personal computer 21 is connected to a first input / output interface 52 via a connection cable 51, and each component box 25 of the work table 11 is connected to the first input / output interface 52 via a connection line 53. ,... Are connected to an indicator lamp 33 and a take-out sensor 36. The first interface 52 is connected to a second input / output interface 55 provided on the parts shelf 12 via a connection cable 54, and the second input / output interface 55 includes An instruction lamp 43 and a take-out sensor 46 provided in each of the component boxes 26 are connected. The second input / output interface 55 is configured to be connected to another component shelf via a connection cable 56.

  As a result, the personal computer 21 turns on the indicator lamps 33 and 43 of any of the component boxes 25 and 26 to indicate the components to be used, and in the component boxes 25 and 26 by the input from the take-out sensors 36 and 46. It is configured so that it can be determined whether or not the part 31 has been removed.

  The personal computer 21 is connected to the keyboard 23 and the mouse 24, and is connected to a storage device 61 for reading and writing data from and to a recording medium. Thereby, it is configured such that input of image data and the like of work procedures displayed on the display device 22 and work time data in each work process can be read from and written to the recording medium. Furthermore, the display device 22 and the speaker 62 are connected to the personal computer 21 so that a work procedure can be displayed on the display device 22 and a warning sound at the time of an error can be output from the speaker 62. Yes.

  The operation of the present embodiment according to the above configuration will be described with reference to the flowchart shown in FIG.

  That is, when starting a series of assembling operations, the personal computer 21 of the assembling apparatus 1 is on standby until the operator authentication information is input (K1). The given authentication information is input to the personal computer 21 using the keyboard 23 and the mouse 24 to perform worker registration (S1).

  In the personal computer 21 to which the authentication information is input, it is determined whether or not the input authentication information is registered in advance, and it is determined whether or not it is a designated worker and can be authenticated (K2). If it is not registered and authentication cannot be performed, “authentication impossible” is displayed on the display device 22, and the process branches to step K1. On the other hand, if the authentication information is registered and it is possible to identify the designated worker, the process waits until the work selection information is input (K4).

  In this standby state, when the operator selects a product to be assembled using the keyboard 23 or the mouse 24 and inputs work information (S2), the personal computer 21 determines whether the selection information is selectable. (K5). If the selection information cannot be selected, “not selectable” is displayed on the display device 22 (K6), and the process branches to step K4. On the other hand, if the selection information can be selected, the selected assembly operation is performed. The work procedure is set in (K7).

  The personal computer 21 displays the contents of the work instruction on the screen of the display device 22, and the instruction lamps 33, 25 of the parts boxes 25, 26 containing the parts 31 used in the work process (initially the first work process). Since 43 is lit (K8), the operator takes out the component 31 from the component boxes 25 and 26 whose indicator lamps 33 and 43 are lit (S3). Then, the personal computer 21 detects the presence / absence of input from each of the take-out sensors 36, 46,..., And whether or not the parts 31 of the parts boxes 25, 26 that have turned on the instruction lamps 33, 43 have been taken out. That is, it is determined whether or not the component 31 for which the removal instruction has been issued has been removed (K9).

  At this time, when a part 31 other than the part 31 of the parts box 25, 26 in which the instruction lamps 33, 43 are lit, that is, a part 31 other than the part 31 that has instructed the take-out instruction, a “part error” is displayed. While displaying on the display device 22 and outputting a warning sound from the speaker 62 (K10), the process returns to the step K8. Thereby, the screen display on the display device 22 does not proceed to the instruction content of the next work process, and it is possible to reliably prevent an attachment error of the component 31.

  On the other hand, when it is determined in step K9 that the parts 31 of the parts boxes 25 and 26 whose indicator lamps 33 and 43 have been lit, that is, the parts 31 that have been instructed to be taken out, the work procedure information is displayed on the display device. 22 is displayed (K11). The work procedure information includes the attachment location and attachment method of the component 31, and outputs not only character information and monochrome images, but also color images, moving images, sounds, and the like as necessary. Thereby, the worker performs a predetermined work according to the screen display of the display device 5.

  In this work process, by using the keyboard 23 and mouse 24, the operator can input detailed information such as displaying detailed procedures, registering quality recording items, and suspending or resuming work. (S4) The personal computer 21 receives information each time, and performs information reception processing each time by displaying detailed procedures, recording quality information, suspending or resuming work (K12). .

  When the attachment of the component 31 is completed, the fact that the work step is completed is input using the keyboard 23 and the mouse 24 (S5), and the specified regular component 31 is taken out by the personal computer 21. Whether or not the work time from the current time (K11 to K13) is recorded on the recording medium and the statistical process is performed (K13), and then a series of work steps are completed and the whole process for one product is completed. Is determined (K14). If another work process remains, the process branches to Step K8 to start the next work process.

  More specifically, the personal computer 21 turns on the indicator lamps 33 and 43 of the component boxes 25 and 26 in which the components 31 to be used in the next work process are stored (K8). , 43 are taken out from the component boxes 25, 26 (S3). At this time, the personal computer 21 can determine whether or not the previous work process has been performed by detecting the presence or absence of an input from each of the take-out sensors 36, 46,.

  At this time, it is determined whether or not the parts 31 of the parts boxes 25 and 26 whose indicator lamps 33 and 43 are lit are taken out (K9), and when parts 31 other than the designated part 31 are taken out, "Part error" is displayed on the display device 22, a warning sound is output from the speaker 62 (K10), and the process returns to step K8. On the other hand, when the designated part 31 is taken out in the step K9, the work procedure information in the next work process is displayed on the display device 22 (K11), and the steps K12 to K14 are executed.

  Thus, by detecting that the parts 31 designated by the take-out sensors 36 and 46 are taken out, it can be determined that the previous work process has been carried out, and the display on the display device 22 is the next. It is changed to the work procedure of this work process.

  If it is determined in step K14 that a series of work steps have been completed and the product has been completed, the process waits until the presence / absence of work continuation is input (K15). Whether to continue or not is input using the keyboard 23 or the mouse 24 (S6). In the personal computer 21 that has received this input, when an input to end the assembling work is made (K16), the processing by the operator is finished while an input to continue the assembling work is made. The process branches to step K8, and the assembly of the next product is started from the first work process.

  As described above, the worker takes out the parts 31 from the parts boxes 25 and 26 in which the instruction lamps 33 and 43 are lit, and performs a series of assembling work only by performing the work according to the work procedure displayed on the display device 22. Can assemble the product.

  Therefore, an assembly work can be performed without taking out a work procedure manual for each work process, even if it is not an expert who grasps all work processes and stores the arrangement and attachment method of each part. In addition, it is possible to prevent mistakes due to carelessness of the operator as compared with assembly work that relies on the operator's attention and memory.

  Furthermore, since the work instruction can be created as an electronic document, it does not occupy a part of the workbench and does not deteriorate due to repeated use as compared with the case of using a paper medium. In addition, it is possible to flexibly cope with creation and modification of work instructions, and it is possible to combine contents that cannot be handled by paper media such as voice and moving images.

  And since it is possible to detect that each work process has been carried out, the work time required for each work process is automatically recorded and aggregated, so that the work time for each worker and each work process Can be grasped, and work conditions such as work hours can be analyzed. In addition, it is possible to record work instructions and quality during work.

  Since the work procedure can be programmed using the personal computer 21, even when the work target product is changed, it is possible to cope with the change of the program. In addition, it is possible to cope with a change in work process by changing a part of the program.
