Description

[Technical Field]

[0001] The present disclosure relates to an inspection device and a program for inspecting an item to be inspected. [Background technology]

[0002] For example, an amusement machine is an inspected product that has many parts attached to the front and back of the board, such as gimmicks for effects, LCD units, various circuit boards for main control and display control, and various resin molded parts such as prize slots. These parts are inspected at the time of delivery to ensure they are installed correctly. Inspections include many items such as missing parts, missing parts, mixed-up parts, incorrect part installation positions, incorrect part installation heights, missing screws that attach parts to the game board, improper installation such as poor connector fit, missing stickers with serial numbers, incorrect serial numbers or circuit board numbers, discoloration or uneven coloring of gimmicks for effects, and incorrect gimmick positioning.

[0003] For inspections, cameras (image sensors) and other sensors for measuring distance, weight, etc. are used as appropriate depending on the inspection item. Since there are a wide variety of inspection targets and inspection items, it is difficult to cover everything with a single camera or sensor.

[0004] A plurality of cameras and sensors are arranged, for example, along a conveyor. Gaming machines transported by the conveyor are photographed and measured each time they pass by the cameras and sensors.

[0005] In addition, a gaming machine installation stand is provided for each camera and sensor, and an inspection worker sets the gaming machine on the installation stand and performs imaging, then transports the gaming machine to the next installation stand, sets it again, and performs imaging, repeating this process until all imaging is completed.

[0006] In either method, the image capture by the camera and the judgment process operate on separate time axes, and the judgment results are displayed sequentially on the screen each time the judgment process is completed, separate from the image capture.

[0007] For gaming machines that are judged to be "incorrect (defective, inappropriate, non-compliant)," the inspection worker must remove the gaming machine from its installation base, transport it to a repair facility, check the affected area, perform repair work such as replacing or reinstalling parts as appropriate, and then transport it to a re-inspection facility for re-inspection, which is an extremely burdensome and inefficient process.

[0008] In addition, with the latter method, since the installation machines are separated into multiple installation machines, transporting the gaming machines and repeatedly setting them up on each installation machine is not only a heavy workload but also inefficient. Summary of the Invention [Problem to be solved by the invention]

[0009] The purpose is to improve the efficiency of the inspection work for the products to be inspected. [Means for solving the problem]

[0010] An inspection device for an item to be inspected according to an embodiment of the present invention comprises a mounting table for mounting the item to be inspected, at least one camera for capturing an image of the item to be inspected mounted on the mounting table, at least one sensor which is a weight sensor, distance sensor, metal sensor, non-contact resin sensor or contact resin sensor for measuring the item to be inspected or its parts mounted on the mounting table, a first judgment unit for judging whether the item to be inspected is genuine based on an image captured by the camera, a second judgment unit for judging whether the item to be inspected or its parts is genuine based on measurement data from the sensor, a display unit for displaying the results of judgment by the first judgment unit and the second judgment unit, an operation switch for instructing the start of inspection, and a sequence control unit which, in response to operation of the operation switch, sequentially executes a series of processes relating to capturing an image by the camera, judgment by the first judgment unit and displaying the results of the judgment by the first judgment unit, and a series of processes relating to measurement by the sensor, judgment by the second judgment unit and displaying the results of the judgment by the second judgment unit, and which, when the judgment result is "false", stops the process without proceeding to the next series of processes at that point and waits for operation of the operation switch.

[0012] Hereinafter, an inspection device for inspected products according to an embodiment of the present invention will be described with reference to the drawings. The inspected products include gaming machines, electronic devices such as smartphones, mechanical products such as transmission gears, and various other products. Here, the inspected products will be described as gaming machines.

[0013] The inspection device according to this embodiment has two types: (1) an inspection mode using at least one camera and at least one sensor other than a camera, and (2) an inspection mode using multiple sensors other than a camera. The camera includes an imaging lens and an image sensor that receives light through the imaging lens.

[0014] Typical examples of sensors other than cameras include weight sensors, distance sensors, metal sensors, non-contact resin sensors, and contact resin sensors, but other sensors may also be used. In this embodiment, sensors are appropriately selected and combined depending on the inspection target and inspection items.

[0015] Based on the images captured by the camera, for example, the color of the gimmick (discoloration, uneven color, etc.), the position of the gimmick, the color of the resin molded product, missing parts, missing screws for fixing parts to the board, loose connectors, partially inserted connectors, part height, missing stickers with serial numbers, missing sheet metal, etc. The images captured by the camera are also used to read two-dimensional codes such as QR Codes (registered trademark) and board numbers to identify the serial number, etc.

[0016] The weight sensor may be a pressure sensor or a strain sensor, either of which may be applied to the inspection device according to this embodiment. Based on the measurement data of the weight sensor, for example, the inspection device may check for missing molded parts of the product to be inspected.

[0017] Examples of distance sensors include laser sensors, infrared sensors, and ultrasonic sensors, any of which are applied to the inspection device according to this embodiment. Based on the measurement data of the distance sensors, for example, loose connectors, missing connectors, missing screws, missing parts, reversed part installation, missing springs, and reversed spring installation are inspected.

[0018] As the metal sensor, for example, an inductive proximity sensor is applied to the inspection device according to this embodiment. Based on the measurement data of the metal sensor, for example, missing screws are inspected.

[0019] As the contact sensor, for example, a contact-type resin sensor is applied to the inspection device according to this embodiment.

[0020] The inspection device according to this embodiment uses, for example, a microswitch as a contact-type resin sensor. Based on measurement data from the contact sensor, the inspection device can inspect for molding defects, missing parts, and fitting defects in resin molded products.

[0021] The inspection device according to this embodiment is configured to use a non-contact resin sensor as a proximity sensor. An example of a non-contact resin sensor is a capacitance proximity sensor. Based on measurement data from the proximity sensor, the device inspects for molding defects, missing parts, and fitting defects in resin molded products.

[0022] During an actual inspection, the inspection worker operates an operating switch (inspection switch), which triggers a series of processes to be carried out in sequence: capturing an image using a camera or sensor, making a judgment based on the image, and displaying the judgment result; and measuring using a camera or sensor, making a judgment based on the measurement data, and displaying the judgment result.If the judgment result is "incorrect (non-conforming, inappropriate, defective)," the series of processes will stop at that point and await operation of the operating switch.

[0023] When the inspection stops, the inspection worker identifies the cause of the error, and if it is determined to be a cause that can be solved on the spot, repairs are made on the spot without moving the gaming machine. When the repair is complete, the inspection worker operates the operation switch again. This operation resumes the inspection. Since repairs can be made on the spot, it is more efficient than transporting the gaming machine to another location for repairs.

[0024] When the inspection is restarted, it is restarted by returning to the initial series of processes.No matter at what stage the inspection is stopped, it is restarted by returning to the initial series of processes, so even if new non-conformities, improperness, or defects occur due to the repair work, such as parts being out of position, they can be inspected again.

[0025] Repairs and inspections can be resumed as many times as the inspector deems necessary. If the problem persists after repairs, or if the inspector determines that the problem cannot be solved on the spot, the inspector will determine that the machine is a non-conforming product or requires specialized repairs, and will move the machine to a designated location. Specific details are provided below. (First embodiment) 1, the inspection device 1 is composed of an information processing device 10, a first camera 21 for capturing images of the front side of the gaming machine, a second camera 22 for capturing images of the back side of the gaming machine, a distance sensor 23 for measuring target parts such as connectors and screws on the front and back of the gaming machine and the distance to the target parts, a third camera 24 for capturing images of the back side of the gaming machine at close range, an articulated robot device 31 with the distance sensor 23 and third camera 24 attached to the tip of its arm, an inspection switch 33 that an inspection worker operates to start the inspection process, and an inspection lamp 35 for displaying the inspection results in red, blue, etc. The cameras 21, 22, and 24 are each equipped with lighting.

[0026] The information processing device 10 has a processor 11. Connected to the processor 11 via a data / control bus 19 are a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, a storage device 14 such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), an input device 15 such as a keyboard or a mouse, a display 16, and an interface 17. Cameras 21, 22, and 24, an articulated robot device 31, an inspection switch 33, and an inspection lamp 35 are connected to the processor 11 via the interface 17.

[0027] The processor 11 is composed of a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). The processor 11 executes an inspection program loaded from the storage device 14 into the RAM 12 to perform inspection processing for the gaming machine. The RAM 12 functions as the main memory, work area, etc. of the processor 11. The ROM 13 stores a BIOS (Basic Input Output System), an operating system program (OS), etc. executed by the processor 11. The storage device 14 stores various data such as the inspection program according to this embodiment, data of images captured by the cameras 21, 22, and 24, reference image data, data required for the judgment processing such as standard values ​​and thresholds, and judgment results.

[0028] 2 shows the functional configuration of the processor 11. By executing the inspection program, the processor 11 functions as a control unit 101 that controls the entire information processing device, a first camera controller 121 that drives the first camera 21, a second camera controller 122 that drives the second camera 22, a sensor controller 123 that drives the distance sensor 23, a third camera controller 124 that drives the third camera 24, a robot controller 131 that controls the operation of the articulated robot device 31, a switch detection unit 133 that detects the state of the inspection switch 33, and a lamp driver 135 that drives the inspection lamp 35.

[0029] Furthermore, by executing the above-mentioned inspection program, the processor 11 functions as a storage management unit 103 that controls the writing / reading of image data, measurement data, etc. to the storage device 14, a first judgment unit 104 that judges whether the gaming machine is correct or incorrect with respect to the inspection item for which it is responsible based on an image captured by the first camera 21, a second judgment unit 105 that judges whether the gaming machine is correct or incorrect with respect to the inspection item for which it is responsible based on an image captured by the second camera 22, a third judgment unit 106 that judges whether the gaming machine is correct or incorrect with respect to the inspection item for which it is responsible based on measurement data (distance data) measured by the distance sensor 23, a fourth judgment unit 107 that judges whether the gaming machine is correct or incorrect with respect to the inspection item for which it is responsible based on an image captured by the third camera 24, a display control unit 108 that turns on the inspection lamp 35 and displays details of the judgment results on the display 16, and an inspection sequence control unit 102 that controls the first to third camera controllers 121, 122, 124, the sensor controller 123, the robot controller 131, and the lamp driver 135 in accordance with a predetermined inspection sequence.

[0030] Fig. 3 shows an installation stand for installing a gaming machine at an inspection position, together with the first to third cameras 21, 22, 24, the distance sensor 23, and the articulated robot device 31. Fig. 4 shows a state in which a gaming machine is set on an installation stand 242. The installation stand 242 has a base 245, and a support plate 243 is vertically erected on the base 245. The support plate 243 is, for example, rectangular, and has, for example, a rectangular opening 244 in its center. The gaming machine 61 is supported by the support plate 243 and installed vertically on the base 245. The base 245 is held horizontally by the stand 241, so the gaming machine 61 is installed vertically by the support plate 243.

[0031] The first camera 21 is supported by a base 241 via an arm (not shown) at a position where it can capture an image of the front surface of the gaming machine 61, which is installed vertically, through the opening 244. The second camera 22 is supported by a base 241 via an arm (not shown) at a position where it can directly capture an image of the back surface of the gaming machine 61, which is installed vertically.

[0032] The articulated robot device 31 is mounted on a stand 241 at a position to the side of the support plate 243, and a distance sensor 23 and a third camera 24 are attached to the tip of the arm of the articulated robot device 31. Depending on the movement of the articulated robot device 31, the distance sensor 23 can measure the distance to the target component at any proximity position and any attitude, and the third camera 24 can take images of the front and back of the gaming machine 61 from a proximity position in any attitude. In addition, an inspection switch 33 and an inspection lamp 35 are mounted on the stand 241.

[0033] 5 and 6 show the procedure of the inspection operation by the inspection device 1. In addition, dashed lines in FIGS. 5 and 6 indicate the work process performed by the inspection worker. The gaming machine (inspected product) 61 to be inspected is carried to the installation stand 242 by the inspection worker and installed on the installation stand 242 (S11). The gaming machine 61 is placed on a base 245 and is supported vertically by a support plate 243. The front surface of the installed gaming machine 61, except for its peripheral parts, is exposed through an opening 244 in the support plate 243. The back surface of the installed gaming machine 61 is exposed over its entire surface.

[0034] The inspection sequence control unit 102 waits for the switch detection unit 133 to detect an operation (pressing) of the inspection switch 33 by the inspection operator (S12).

[0035] When the switch detection unit 133 detects that the inspection operator has operated the inspection switch 33 (S12; Yes), the inspection sequence control unit 102 starts the inspection process.

[0036] The inspection sequence control unit 102 controls the first camera controller 121 to cause the first camera 21 to capture an image of the front side of the gaming machine 61 (S13). More specifically, under the control of the inspection sequence control unit 102, the first camera 21 repeatedly captures images of the front side of the gaming machine while, for example, changing the wavelength of the light source. Note that, in order to improve color discrimination, eight types of illumination wavelengths are switched sequentially, and imaging by the camera 21 is repeated in synchronization with this.

[0037] The first determination unit 104 determines whether each of these inspection items is correct or incorrect from the eight images with different illumination wavelengths (S14). Inspection items for the surface of the gaming machine include, for example, the color of the gimmick (discoloration, color unevenness, etc.), the position of the gimmick, the position of the LCD screen, etc.

[0038] When the first judgment unit 104 judges that at least one of these inspection items is incorrect (incorrect), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red," and when all of these inspection items are correct (correct), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S15). Although not shown, the judgment results for each of these inspection items are displayed on the display 16. When the inspection lamp 35 turns on in "red," the inspection operator can visually identify which inspection items are incorrect.

[0039] If any one of the inspection items relating to the surface of the gaming machine 61 is incorrect (incorrect) (S16; NG), the inspection sequence control unit 102 stops the inspection without proceeding to the second series of processes and waits for the operation of the inspection switch 33.

[0040] When the inspection is stopped, the inspection worker performs the following (1) or (2) according to his / her own judgment (S17).

[0041] (1) If it is determined that the gaming machine 61 can be repaired on the spot, the gaming machine 61 is repaired on the spot while it is installed on the installation base 242, and a re-inspection is attempted. Of course, a re-inspection may also be attempted without repair. (2) If it is determined on the spot that the machine cannot be repaired, the machine is transported to an authorized repair facility, or the gaming machine 61 is transported from the installation stand 242 to a shelf for rejected items, and the next gaming machine 61 to be inspected is installed on the installation stand 242.

[0042] Returning to step S12, when the inspection worker operates the inspection switch 33 (S12; Yes), the above-described first series of processes (S13-S15) is executed for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102. The repair and re-inspection of the gaming machine 61 (first series of processes (S13-S15)) can be repeated any number of times by operating the inspection switch 33 at the discretion of the inspection worker.

[0043] When all inspection items related to the front surface of the gaming machine 61 are correct (proper), the process automatically proceeds to an inspection of the back surface of the gaming machine 61 using the second camera 22 under the control of the inspection sequence control unit 102 (second series of processes, S18-S20) (S16; OK).

[0044] Under the control of the inspection sequence control unit 102, the second camera 22 captures an image of the entire rear surface of the gaming machine in a wide field of view (S18).

[0045] The second determination unit 105 determines whether each inspection item is correct or incorrect from the image acquired by the second camera 22 (S19). Inspection items on the back side of the gaming machine include, for example, whether a sticker bearing the serial number is missing, whether metal plate is missing, whether screws for attaching parts to the back of the gaming board are missing, reading of the board number printed on the board, whether other parts are missing, etc.

[0046] If at least one of these inspection items is incorrect (missing item, reading error), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red," and if all of these inspection items are correct (no missing item, proper reading), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S20). The judgment results of these inspection items are displayed on the display 16. When the inspection lamp 35 turns "red," the inspection operator can visually identify which inspection item is incorrect.

[0047] If any one of the inspection items related to the back surface of the gaming machine 61 is incorrect (S21; NG), the inspection sequence control unit 102 stops the inspection without proceeding to the third series of processing and waits for the operation of the inspection switch 33.

[0048] When the inspection stops, the inspection worker executes the above-mentioned (1) or (2) (S22). Then, the process returns to step S12, and when the inspection worker operates the inspection switch 33 (S12; Yes), inspection is resumed from the first series of processes (S13-S15) described above for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102. As repair work on the back surface of the gaming machine 61 occurs, it cannot be said that new defects will not occur on the front surface of the gaming machine 61, and by resuming from the first series of processes (S13-S15) using the first camera 21, high inspection accuracy can be achieved.

[0049] The first series of steps (S13-S15) and the second series of steps (S18-S20) can be repeated any number of times at the discretion of the inspector.

[0050] When all of the inspection items relating to the front and back surfaces of the gaming machine 61 are correct (proper), the inspection sequence control unit 102 automatically proceeds to inspection by the distance sensor 23 (third series of processes) (S21; OK).

[0051] In the third series of processes, the robot controller 131 controls the articulated robot device 31, causing the distance sensor 23 to move along a predetermined trajectory close to the front or back of the gaming machine and change its posture while repeatedly acquiring distance data (S23).

[0052] For example, the distance sensor 23 is positioned and oriented such that its optical axis is parallel to the mating direction of the connector and is a predetermined distance away from the rear surface of the connector housing. The third determination unit 106 determines whether the part or components are proper or not based on the distance measured by the distance sensor 23. For example, the distance measured by the distance sensor 23 is compared with a distance preset for when the connector is properly mated with the receptacle, and if the measured distance is within a preset proper range, it is determined that the connector is properly mated (correct). If the measured distance is within a range slightly larger than the proper range (improper range), it is determined that the connector is not properly mated, i.e., loose or partially inserted (incorrect). Furthermore, if the measured distance exceeds the improper range, it is determined that the connector is missing (incorrect).

[0053] Similarly, the distance to the head of the screw that secures components such as the main control circuit to the circuit board is measured, and based on that measured distance it is determined whether the screw is properly tightened, incompletely tightened, or missing.

[0054] The third determination unit 106 determines whether each test item is correct or incorrect based on the distance measured by the distance sensor 23 (S24).

[0055] If at least one of these test items is incorrect (incorrect), the test sequence control unit 102 controls the lamp driver 135 to turn on the test lamp 35 in "red," and if all of these test items are correct, the test sequence control unit 102 controls the lamp driver 135 to turn on the test lamp 35 in "blue" (S25), and stops the test.

[0056] When any one of the proximity inspection items of the gaming machine 61 is incorrect (S26; NG), The inspection sequence control unit 102 stops the inspection without proceeding to the next fourth series of steps and waits for the operation of the inspection switch 33. The inspection worker executes (1) or (2) described above (S27). Then, the process returns to step S12. When the inspection worker operates the inspection switch 33 (S12; Yes), inspection is resumed from the initial first series of steps (S13-S15) for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102. Rather than resuming from the third series of steps that were erroneously determined, the inspection is resumed from the initial first series of steps (S13-S15) and the first, second, and third series of steps are re-executed. This makes it possible to determine the occurrence of a new defect due to repair, etc., and achieves high inspection accuracy.

[0057] When all of the test items in the third series of processes are correct (proper), the test sequence control unit 102 automatically proceeds to a proximity test of the gaming machine 61 (fourth series of processes) (S26; OK).

[0058] In the fourth series of processing, the robot controller 131 controls the articulated robot device 31, causing the third camera 24 to move along a predetermined trajectory close to the front or back surface of the gaming machine and change its posture while repeatedly taking images (S28).

[0059] The third determination unit 106 determines whether each inspection item is correct or incorrect based on the images acquired by the third camera 24 (S29). Proximity inspection items for gaming machines include, for example, missing or improperly mated connectors (loose, partially inserted), component height, reading of a two-dimensional code (QR Code (registered trademark)) affixed to the gaming board 51, and missing other components.

[0060] If at least one of these inspection items is incorrect (non-conformance; missing or poorly fitted connector, abnormal part height, missing part, reading error), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red", and if all of these inspection items are correct (no missing parts, proper reading), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S30) and stops the inspection.

[0061] If any one of the proximity inspection items of the gaming machine 61 is incorrect (S31; NG), the inspection worker executes the above-mentioned (1) or (2) (S32). Then, the process returns to step S12, and when the inspection worker operates the inspection switch 33 (S12; Yes), the inspection is resumed from the first series of steps (S13-S15) described above for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102. Rather than resuming from the fourth series of steps that were determined to be unsuitable, the inspection is resumed from the initial first series of steps (S13-S15) and the second, third, and fourth series of steps are re-executed, making it possible to determine the occurrence of new defects due to repairs, etc., and achieving high inspection accuracy.

[0062] If all of the proximity inspection items for the gaming machine 61 are positive (S31; OK), the inspection worker transfers the gaming machine 61 to the shelf for acceptable products (S33). If inspection of all items to be inspected has been completed (S34; Yes), the inspection work ends. If inspection of all items to be inspected has not been completed (S34; No), the next gaming machine 61 to be inspected is placed on the installation table (S35), and the process returns to the inspection process S12.

[0063] As described above, according to this first embodiment, inspections using multiple cameras 21, 22, 24 and distance sensors 23 can be completed while the gaming machine 61 to be inspected remains installed on the installation stand 242, and there is no need to transport the gaming machine 61 to a different installation location for each inspection using the cameras 21, 22, 24 and distance sensors 23, thereby making the inspection work more efficient.

[0064] Furthermore, if there is even one error in the inspection results, the inspection process stops, so repairs can be made on the spot and re-inspection can be carried out immediately, which is more efficient than transporting the gaming machine 61 to another location for repairs, etc.

[0065] Furthermore, an opening 244 is formed in the support plate 243 of the installation stand 242, and an inspection worker can access the gaming machine 61 through the opening 244, so that repairs can sometimes be carried out while the gaming machine 61 is standing on the installation stand 242, which improves the workability of repairs.

[0066] When the inspection is restarted, it can be resumed by returning to the first series of processes with a single action.No matter at what stage the inspection is stopped, the process returns to the first series of processes and the entire inspection is carried out again, so even if new non-conformities, improperities or defects arise, such as parts being misaligned due to repair work, they can be inspected again, ensuring high inspection accuracy.

[0067] In the above description, an installation base for installing a gaming machine vertically (plumbing) has been described. However, the installation base may also have a structure for installing a gaming machine horizontally. As shown in FIG. 7, the installation base 246 has a rectangular base 248 that is the same size as or slightly larger than the gaming machine 61, and four legs 247 are vertically erected at the four corners of the base 248. The gaming machine 61 is supported horizontally on the legs 247 with its surface facing downward. A rectangular opening 249 is opened in the center of the base 248. The surface of the gaming machine 61 supported horizontally on the legs 247 is exposed downward through the opening 249. (Second embodiment) In the first embodiment described above, an example in which three cameras and one distance sensor are combined to complete the inspection of a gaming machine is described, but in this second embodiment, an example in which one camera, one weight sensor, and one distance sensor are combined to complete the inspection of a gaming machine is described. Note that parts that overlap with those in the first embodiment are given the same reference numerals, and their explanations are omitted as much as possible.

[0068] As shown in FIG. 8, the inspection device 1 is equipped with a weight sensor 41, a distance sensor 42, and a camera 43. The weight sensor 41 is equipped to measure the total weight of the installation base 242 and the gaming machine 61. The part to be inspected may be hidden by other resin molded products and not exposed when viewed from the front or back side, and the camera or sensor cannot capture or measure it. If the part to be inspected is missing, the total weight of the installation base 242 and the gaming machine 61 is reduced by the weight of the missing part. By using the weight sensor 41, it is possible to inspect for missing parts.

[0069] The distance sensor 42 is attached to the tip of the arm of the articulated robot device 31, and is equipped to approach the screws that attach target components such as the main control circuit to the back of the gaming board to inspect for missing parts, the state of attachment, etc. The camera 43 is equipped to take images of the front side of the gaming machine 61 and inspect the color (discoloration, uneven color, etc.) of, for example, a device (gimmick) used for performance as a resin molded product.

[0070] 9, by executing the inspection program, processor 11 functions as first sensor controller 141 that drives weight sensor 41, second sensor controller 142 that drives distance sensor 42, and camera controller 143 that drives camera 43. Furthermore, by executing the inspection program, processor 11 functions as first determination unit 204, second determination unit 205, and third determination unit 206. First determination unit 204 compares the weight measured by weight sensor 41 with the weight (proper weight) in a state where all parts, etc. are installed without any missing parts, and determines, based on the difference, whether all parts, etc. are installed properly with no missing parts or whether at least one part is missing, and estimates the missing part or a combination of multiple missing parts.

[0071] The second determination unit 205 determines, based on the measurement data (distance data) measured by the distance sensor 42, whether the distance from the distance sensor 42 to the head of the screw matches the distance when the screw is properly tightened (proper distance) (proper), or whether the distance from the distance sensor 42 to the head of the screw does not match the proper distance and the screw is not properly tightened. The third determination unit 206 determines, based on the image captured by the camera 43, whether the color of the resin molded product is proper or not.

[0072] As shown in Figure 10, the weight sensor 41 is interposed between the base 245 of the installation stand 242 and the platform 241, and measures the total weight of the installation stand 242 and the gaming machine 61 installed on the installation stand 242. The distance sensor 42 is a distance sensor 23 attached to the tip of the arm of the articulated robot device 31. Depending on the movement of the articulated robot device 31, the distance sensor 23 measures the distance to the target component at any proximity position and any posture. The camera 43 can capture images of the front and back of the gaming machine 61 from a proximity position and at any posture. An inspection switch 33 and an inspection lamp 35 are installed on the platform 241.

[0073] 11 and 12, an inspection worker places a gaming machine (inspection target) 61 on the installation stand 242 (S11). When the inspection worker operates (presses) the inspection switch 33 (S12), the inspection sequence control unit 102 controls the first sensor controller 141 to first execute a first series of processes (S41, S42, S15).

[0074] The weight sensor 41 measures the total weight of the installed base 242 and the gaming machine 61 (S41). The first determination unit 204 determines whether at least one molded product is missing based on the weight measured by the weight sensor 41 (S42). As described above, the total weight (proper weight (threshold)) of the weight of the gaming machine 61 with no missing parts and all parts properly attached and the weight of the installed base 242 is known. When at least one part is missing, the measured weight is lower than the proper weight. In this case, the first determination unit 204 determines that at least one part is missing as "incorrect (incorrect)." Furthermore, the weight of each of all parts is known, and the missing part or combination of multiple missing parts can be estimated from the difference between the measured weight and the proper weight.

[0075] When the judgment result of the first judgment unit 204 is incorrect (incorrect), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red," and when the judgment result of the first judgment unit 204 is correct (correct), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S15). Although not shown, the display 16 displays a part number or the like that identifies the part that is presumed to be missing. When the inspection lamp 35 turns on in "red," the inspection worker can visually identify which part is missing.

[0076] If the weight determination is incorrect (inappropriate) (S16; NG), the inspection sequence control unit 102 stops the inspection without proceeding to the second series of processes, and waits for the inspection switch 33 to be operated.

[0077] When the inspection stops, the inspection worker performs the following (1) or (2) according to his / her own judgment (S17): (1) If it is determined that the gaming machine 61 can be repaired on the spot, the missing part is attached on the spot while the gaming machine 61 remains installed on the installation stand 242; or (2) If it is determined that the gaming machine 61 cannot be repaired on the spot, the gaming machine 61 is transported to an authorized repair facility, or the gaming machine 61 is transported from the installation stand 242 to a reject shelf, and the next gaming machine 61 to be inspected is installed on the installation stand 242. After the above-mentioned (1) or (2) action is taken, the process returns to step S12, and when the inspection worker operates the inspection switch 33 (S12; Yes), the first series of processes (S41, S42, S15) described above are executed for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102. The repair and re-inspection of the gaming machine 61 (the first series of processes (S41, S42, S15)) can be repeated any number of times at the discretion of the inspection worker.

[0078] If the weight determination is correct (appropriate), the process automatically proceeds to an inspection using the distance sensor 42 (a second series of processes, S43, S44, S20) under the control of the inspection sequence control unit 102 (S16; OK).

[0079] In the second series of processes, the robot controller 131 controls the articulated robot device 31, so that the distance sensor 42 moves on a predetermined trajectory close to the front or back of the gaming machine and repeatedly acquires distance data while changing its posture (S43). For example, the distance sensor 42 measures the distance to the head of a screw that secures the main control circuit or the like to the circuit board, and determines based on that distance whether the screw is properly tightened, incompletely tightened, or missing.

[0080] The second determination unit 205 determines whether each inspection item is correct or incorrect based on the distance measured by the distance sensor 42 (S44). If at least one screw is missing or at least one screw is incompletely tightened, the determination result is incorrect, and the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in red, and if the determination result is correct, meaning that all of the screws to be inspected have been properly tightened, the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in blue (S20), and the inspection is stopped.

[0081] If the determination result is false (S21; NG), the inspection worker executes the above-mentioned (1) or (2) (S22). Then, the process returns to step S12, and in response to the inspection worker operating the inspection switch 33 (S12; Yes), inspection is resumed from the first series of processes (S41, S42, S15) described above for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102. Rather than resuming from the second series of processes using the distance sensor 42, the inspection is resumed from the first series of processes (S41, S42, S15) using the weight sensor 41, and the second series of processes (S43, S44, S20) using the distance sensor 42 is re-executed. This makes it possible to determine the occurrence of a new defect due to repair, etc., and achieves high inspection accuracy.

[0082] When all of the inspection items based on the measurement data of the distance sensor 42 are correct (appropriate), the inspection sequence control unit 102 automatically proceeds to the next inspection using the camera 43 (third series of processes) (S21; OK).

[0083] The inspection sequence control unit 102 controls the camera controller 243 to cause the camera 43 to capture an image of the front side of the gaming machine 61 (S45). For example, the camera 43 sequentially switches between, for example, eight different illumination wavelengths for the surface of the gaming machine, and the camera 43 repeatedly captures images in synchronization with this. The third determination unit 113 determines whether the game is correct or incorrect from the eight images captured with different illumination wavelengths (S46). Inspection items for the front side of the gaming machine include, for example, the color of the gimmick (discoloration, color unevenness, etc.) for the effect, the position of the gimmick, the position of the LCD screen, etc.

[0084] When the third judgment unit 206 judges that at least one of these inspection items is incorrect (incorrect), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red," and when all of these inspection items are correct (correct), the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S25). Note that although not shown, the display 16 displays the judgment results of these inspection items. When the inspection lamp 35 turns on in "red," the inspection operator can visually identify which inspection items are incorrect.

[0085] If any one of the inspection items on the surface of the gaming machine, such as the color (discoloration, color unevenness, etc.) of the mechanism (gimmick) for effect, the position of the gimmick, or the position of the LCD screen, is found to be incorrect (S26; NG), the inspection sequence control unit 102 instructs the inspection worker to execute the above-described (1) or (2) (S27). Then, the process returns to step S12, and when the inspection worker operates the inspection switch 33 (S12; Yes), the inspection is resumed from the first series of steps (S41, S42, S15) described above. Rather than resuming from the third series of steps using the camera 43, the process is resumed from the first series of steps using the weight sensor 41 (S41, S42, S15), and the second series of steps using the distance sensor 42 (S43, S44, S20) and the third series of steps using the camera 43 (S45, S46, S25) are re-executed. This makes it possible to determine the occurrence of new defects due to repairs, etc., and achieves high inspection accuracy.

[0086] If all of the inspection items based on the image data from the camera 43 are correct (proper), the inspection worker transfers the gaming machine 61 to the shelf for acceptable products (S33). If inspection of all items to be inspected has been completed (S34; Yes), the inspection work ends. If inspection of all items to be inspected has not been completed (S34; No), the next gaming machine 61 to be inspected is placed on the installation table (S35), and the process returns to the inspection process S12.

[0087] As described above, according to the second embodiment, an inspection can be completed using the weight sensor 41, distance sensor 42, and camera 43, and there is no need to transport the weight sensor 41, distance sensor 42, and camera 43 to a different installation location for each inspection, thereby improving the efficiency of the inspection work.

[0088] Furthermore, if there is even one error in the inspection results, the inspection process stops, so repairs can be made on the spot and re-inspection can be carried out immediately, which is more efficient than transporting the gaming machine 61 to another location for repairs, etc.

[0089] When the inspection is restarted, it can be resumed by returning to the first series of processes with a single action.No matter at what stage the inspection is stopped, the process returns to the first series of processes and the entire inspection is carried out again, so even if new non-conformities, improperities or defects arise, such as parts being misaligned due to repair work, they can be inspected again, ensuring high inspection accuracy. (Third embodiment) In the above, an example (first embodiment) in which three cameras and one distance sensor are combined to complete the inspection of a gaming machine, and an example (second embodiment) in which two sensors (weight sensor, distance sensor) and one camera are combined to complete the inspection of a gaming machine have been described, but in this third embodiment, an example in which two distance sensors are combined to perform the inspection of a gaming machine will be described. Note that parts that overlap with the first and second embodiments are given the same reference numerals, and their description will be omitted as much as possible.

[0090] As shown in FIG. 13, the inspection device 1 is equipped with distance sensors 51 and 52. As shown in FIG. 15, the distance sensor 51 is placed in a position facing the surface of the gaming machine 61. It measures the distance to a target component, for example, a component attached to the surface of the gaming board. From the measured distance, it is possible to determine whether a component is missing or installed backwards, or whether a spring is missing or installed backwards as a component. The distance sensor 52 is attached to the tip of the arm of the articulated robot device 31, and is equipped to approach a target component, for example, a component attached to the surface or back of the gaming board, and inspect for whether a component is missing or installed backwards, or whether a spring is missing or installed backwards as a component, from that distance.

[0091] 14, by executing the inspection program, the processor 11 functions as a first sensor controller 151 that drives the distance sensor 51 and a second sensor controller 152 that drives the distance sensor 52. Furthermore, by executing the inspection program, the processor 11 functions as first and second determination units 304 and 305. The first and second determination units 304 and 305 determine whether a part or a spring is missing or is attached incorrectly based on the measurement data (distance data) measured by the distance sensors 51 and 52.

[0092] As shown in Figures 16 and 17, an inspection worker places the gaming machine (item to be inspected) 61 on the installation stand 242 (S11), and when the inspection worker operates (presses) the inspection switch 33 (S12), the inspection sequence control unit 102 controls the first sensor controller 151 to first execute a first series of processes (S51, S52, S15).

[0093] The distance sensor 51 acquires distance data from the distance sensor 51 to a target component attached to the surface of the gaming machine (S51). The first determination unit 304 determines whether the target component is attached properly (correct (correct)), whether the target component is missing (incorrect (correct)), or whether the target component is attached backwards (incorrect (correct)) based on the measurement data (distance data) measured by the distance sensor 51 (S52). When the target component is attached properly, the distance measured by the distance sensor 51 matches a predetermined appropriate distance. When the target component is missing, the distance measured by the distance sensor 51 is longer than the predetermined appropriate distance. When the target component is attached backwards, the distance measured by the distance sensor 51 is longer or shorter than the predetermined appropriate distance.

[0094] When the judgment result of the first judgment unit 304 is "incorrect (inappropriate)", the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red", and when the judgment result is "correct (appropriate)", the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S15).

[0095] If the determination result is false (S16; NG), the inspection sequence control unit 102 stops the inspection without proceeding to the second series of processes and waits for the operation of the inspection switch 33. The inspection worker executes the above-mentioned (1) or (2) (S17). Then, the process returns to step S12, and in response to the inspection worker operating the inspection switch 33 (S12; Yes), the inspection of the repaired gaming machine 61 or the next gaming machine 61 is resumed under the control of the inspection sequence control unit 102 from the above-mentioned first series of processes (S51, S52, S15).

[0096] If the inspection item based on the measurement data of the distance sensor 51 is correct (appropriate), the inspection sequence control unit 102 automatically proceeds to the next inspection using the distance sensor 52 (second series of processes) (S16; OK).

[0097] The inspection sequence control unit 102 controls the sensor controller 152 to execute a second series of processes (S53, S54, S20). In the second series of processes, the robot controller 131 controls the articulated robot device 31, so that the distance sensor 52 moves along a predetermined trajectory close to the front or back surface of the gaming machine and changes its posture, repeatedly acquiring distance data for each of the multiple target parts (S53).

[0098] The second judgment unit 305 judges whether the target part is installed properly (correct (correct)), whether the target part is missing (incorrect (correct)), or whether the target part is installed backwards (incorrect (correct)) based on the measurement data (distance data) measured by the distance sensor 52 (S54).

[0099] When the judgment result of the second judgment unit 305 is "incorrect (inappropriate)", the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "red", and when the judgment result is "correct (appropriate)", the inspection sequence control unit 102 controls the lamp driver 135 to turn on the inspection lamp 35 in "blue" (S20).

[0100] If the determination result is false (S31; NG), the inspection sequence control unit 102 stops the inspection and waits for the operation of the inspection switch 33. The inspection worker executes the above-mentioned (1) or (2) (S32). Then, the process returns to step S12, and in response to the inspection worker operating the inspection switch 33 (S12; Yes), the inspection is resumed for the repaired gaming machine 61 or the next gaming machine 61 under the control of the inspection sequence control unit 102 from the first series of processes (S51, S52, S15) described above.

[0101] By restarting from the first series of processes (S51, S52, S15) by distance sensor 51 instead of restarting from the second series of processes by distance sensor 52, it is possible to determine the occurrence of new defects due to repairs, etc., and high inspection accuracy can be achieved.

[0102] If all of the inspection items for the gaming machine 61 are correct (S31; OK), the inspection worker transfers the gaming machine 61 to the shelf for acceptable products (S33). If inspection of all items to be inspected has been completed (S34; Yes), the inspection work ends. If inspection of all items to be inspected has not been completed (S34; No), the next gaming machine 61 to be inspected is placed on the installation table (S35), and the process returns to the inspection process S12.

[0103] As described above, according to the third embodiment, it is not necessary to transport the distance sensors 51 and 52 to different installation locations for each inspection, and therefore it is possible to improve the efficiency of the inspection work.

[0104] Furthermore, if there is even one error in the inspection results, the inspection process stops, so repairs can be made on the spot and re-inspection can be carried out immediately, which is more efficient than transporting the gaming machine 61 to another location for repairs, etc.

[0105] When the inspection is restarted, it can be resumed by returning to the first series of processes with a single action.No matter at what stage the inspection is stopped, the process returns to the first series of processes and the entire inspection is carried out again, so even if new non-conformities, improperities or defects arise, such as parts being misaligned due to repair work, they can be inspected again, ensuring high inspection accuracy.

[0106] The present invention is not limited to the above-described embodiments, and various modifications can be made in the implementation stage without departing from the spirit of the invention. Furthermore, the embodiments may be implemented in appropriate combinations, in which case the combined effects can be obtained. Furthermore, the above-described embodiments include various inventions, and various inventions can be extracted by combining the disclosed multiple constituent elements. For example, if the problem can be solved and the desired effect can be obtained even if some constituent elements are deleted from all the constituent elements shown in the embodiments, the configuration from which these constituent elements are deleted can be extracted as an invention.
