Fig. 1 is a block diagram of a structure of a dock broom to be tested in the dock broom detection method according to an embodiment of the present invention. Referring to fig. 1, the to-be-tested wharf sweeping machine mainly includes a grating light 12, a camera 13, a light supplement light 14, and a wharf sweeping machine main board 11 for placing the hardware. The dock sweeping main board 11 includes an MCU chip. It is to be understood that the illustration in fig. 1 is merely an example and is not intended to limit the specific hardware included in the dock under test.

The test of the wharf sweeping can be divided into two stages of pcba (printed Circuit Board assembly) test and module test according to different production stages. Wherein, PCBA refers to the whole process of PCB blank board through SMT loading or through DIP plug-in components. The main hardware to be tested of the to-be-tested wharf comprises a grating lamp 12, a camera 13, a supplementary lighting lamp 14 and the like shown in fig. 1. For PCBA testing, hardware such as a camera 13, a grating light 12, and a fill light 14 may be attached to the dock-sweeping motherboard 11, as shown in fig. 1. Module testing is generally performed after the PCBA testing is completed, the dock sweeping motherboard 11, the grating lamp 12, the camera 13 and the light supplement lamp 14 shown in fig. 1 are packaged as a whole into complete dock sweeping hardware 10, and the complete dock sweeping hardware 10 is tested as a whole to examine the integrity of the dock to be tested when the dock is used.

The detection method of the wharf sweeping head comprises the following steps: and judging whether to perform PCBA test and/or module test according to the complete test state flag bit of the to-be-tested wharf, wherein the complete test state flag bit is used for indicating the test state of the to-be-tested wharf, and the test state comprises a PCBA test state and a module test state. In this embodiment, how to obtain the complete test status flag of the wharf to be tested is not limited. Whether the test item is tested or not can be checked by entering the test item of the wharf broom to be tested.

In some embodiments, before the step of determining whether to perform the PCBA test and/or the module test according to the complete test status flag of the dock under test, the method further includes: and acquiring a complete test state flag bit from a micro control unit of the wharf to be tested. Wherein a Micro Control Unit (MCU) may be included in the dock broom main board 11 as shown in fig. 1.

Fig. 2 is an exemplary flowchart illustrating a detection method of a wharf sweeping head according to an embodiment of the present invention. As shown in fig. 2, the detection method of this embodiment includes the steps of:

step S01: inserting the to-be-tested wharf sweeping head. Specifically, a dock-sweeping test fixture is used in a dock-sweeping test process, and the fixture comprises a test accompanying machine and various test environments. The accompany machine of examining connects the FPC line outward, and the pier of sweeping the quay that awaits measuring passes through the FPC line and is connected with accompany machine of examining. The pier finger to be tested is inserted in the step, and the pier to be tested is buckled on the FPC to be connected with the accompanying testing machine.

Step S02: and acquiring a complete test state zone bit. Namely, test results of the PCBA test and the module test are obtained. The invention does not limit how to obtain the complete test state zone bit.

Step S03: and judging whether the wharf to be tested is tested or not. If yes, go to step S05; if not, the process goes to step S04.

In some embodiments of the present invention, when the dock under test is connected to the test-accompanying machine, a complete test status flag bit is obtained from a Micro Control Unit (MCU) through program setting, and the complete test status flag bit comprises a multi-bit binary character including a first set of binary characters for representing the test status of the PCBA and a second set of binary characters for representing the test status of the module.

To further illustrate the complete test status flag of the present invention, a specific example is given here: the full test status flag bit may be a 16-bit binary character as follows: 1111000011110000, respectively; the first eight characters are the first set of binary characters representing the test results of the PCBA, and the second eight characters are the second set of binary characters representing the test results of the module. The binary word "1" may indicate that the result of a particular test for an item is successful, and a "0" indicates a failure or untested. The test states of the PCBA test and the module test can be checked through the zone bits, and therefore the next step is determined according to the test result. Exemplarily, the PCBA test includes a current test, a code scanning test and a fill-in lamp test, in the first set of binary characters, a first digit counted from left represents a current test result, a second digit represents a code scanning test result, a third digit represents a fill-in lamp test, and if the current test, the code scanning test and the fill-in lamp test of the dock to be tested are successful, the first set of binary characters is: 10100000. according to convention, the condition of each test item in the wharf swept area to be tested can be obtained by reading the complete test state flag bit.

Step S03 may obtain all PCBA tests and module tests of the wharf under test according to the complete test status flag. For example, a specific flag bit may be set in the complete test status flag bit to indicate whether a certain test item has been tested. Or it may be determined whether one of the plurality of test items has been tested. Continuing the above example, for example, it is determined whether a "1" is present in the first set of binary characters tested by the PCBA and whether a "1" is present in the second set of binary characters tested by the module. If there is at least one "1", it is indicated as tested.

Step S04: a green background is displayed. If it is determined in step S03 that the dock broom to be tested has not been tested, a green background is displayed to indicate that the dock broom needs to be tested.

Step S05: and judging whether the test is successful. If it is determined in step S03 that the dock broom to be tested has been tested, the test result is further determined. If yes, go to step S07; if not, the process goes to step S06. Step S05 can be used to determine whether all test items were tested successfully or whether a particular test item was tested successfully.

Step S06: a red background is displayed. If the step S05 determines that the dock broom to be tested does not pass the test, a red background is displayed. Indicating that the wharf under test needs to be tested.

Step S07: a greenish background is displayed. If the step S05 determines that the dock broom to be tested passes the test, a blue-green background is displayed. The dock of the meter to be tested passes the test and does not need to carry out subsequent tests.

Through the steps, the test state of the wharf sweeper to be tested can be known before testing, the test state can be known without entering a complete test program, and in the subsequent steps, the test can be performed only on the untested and untested test items, so that the production efficiency of the wharf sweeper is improved.

In other embodiments, the steps S03 and S05 may be combined into the same step, and according to these embodiments, three different background colors may be given by the result of one judgment.

And judging the wharfs to be tested which need to be tested through the steps, and then testing the wharfs to be tested.

Fig. 3 is an exemplary flowchart of PCBA testing in the detection method of the wharf sweeping terminal according to an embodiment of the present invention. As shown in fig. 3, the PCBA test in this embodiment includes the following steps:

step S11: and acquiring the serial number (SN number) and the firmware version number of the wharf to be detected. And the SN number is a unique identifier of each wharf, and is written into the MCU according to a set rule before testing. The firmware version number is the firmware version information imported by current batch production, and the firmware version is written into the MCU before testing.

Step S12: if the serial number is successfully acquired and the firmware version number is correct, whether to start the PCBA automatic test is judged.

In some embodiments of the invention, when performing PCBA testing, it is necessary to ensure that the correct SN number has been written into the dock-sweeping MCU chip and that the firmware version that the test passed is flushed. The SN number and firmware version number may be read from the MCU. The successful acquisition of the serial number in step S12 means that an SN number is read and is legitimate. If the SN number cannot be read from the MCU or is illegal, the serial number is not successfully acquired.

In some embodiments, the SN number to be read is written according to a specific rule, and if the SN number cannot be read according to the specific rule, it indicates that no SN number or an SN number error is written in the MCU. If no SN number is written, the SN number read will be empty or a default specific character.

After step S12, if the serial number is not successfully obtained or the firmware version number is incorrect, a prompt box is popped up in the software interface for testing, and the testing is not allowed.

Step S13: and if the PCBA automatic test is started, automatically executing the PCBA test item in the PCBA test.

In an embodiment of the present invention, the automatic test is started through a software interface, then each test item is tested according to a set sequence, and a test result of each test item is determined, if a certain test item passes, a next test item is automatically executed, and if a certain test item fails, the test is stopped, and the test item is recorded. Correspondingly, if the automatic test is not started, the test items to be performed are manually controlled by clicking the corresponding test items on the software interface by adopting a manual test method.

Step S14: the PCBA test results were recorded.

In some embodiments, the test result for the PCBA is recorded in a flag bit of the full test status flag bit that corresponds to the PCBA test.

In some embodiments, the PCBA test item and/or the module test item include at least a current test.

In some embodiments, the PCBA test item further comprises one or a combination of any of a fill-in light raster light test and a scan code test.

To further illustrate the PCBA test of the present invention, a specific example is given herein. Fig. 4 is an exemplary flowchart of PCBA testing in the detection method of the wharf sweeping terminal according to an embodiment of the present invention, where the embodiment includes the following steps:

step S110: the SN number and the firmware version number are obtained. And judging the next step to be executed according to the acquired SN number and the firmware version number, if the acquired SN number and the firmware version number are both correct, executing the step S112, otherwise, executing the step S111, namely, ending the test.

Step S112: and judging whether to automatically test. In this embodiment, the PCBA test may be performed automatically or manually through a software interface selection. If the automatic test is started, go to step S113; otherwise, the process goes to step S120.

Step S113: and carrying out a current test. When the automatic test is selected, the PCBA test items in the PCBA test are automatically executed. The order of the test items may be set, and in the embodiment shown in fig. 4, the test items include: the method comprises three items of current testing, light supplementing lamp grating lamp testing and code scanning testing. The sequence of the test items can be adjusted according to the requirement, and preferably, the test sequence is as follows: current test, light filling lamp grating lamp test and code scanning test. Thus, if the current test is not passed, the hardware is not passed, and the next test is not needed; after the current test passes, whether the conditions such as cold solder exist between hardware is judged through the test of the light filling lamp grating lamp, and the code scanning test is only carried out when the two items pass the test.

Step S114: and judging whether the current test is successful. If the current test fails, go to step S128: the test is stopped, and then step S129 is executed: recording the test failure; if the test is successful, step S115 is executed.

Step S115: and testing the light supplementing lamp grating lamp.

Step S116: and judging whether the test of the light supplementing lamp grating lamp is successful or not. If the light supplement lamp grating lamp test fails, go to step S128: the test is stopped, and then step S129 is executed: recording the test failure; if the test is successful, step S117 is executed.

Step S117: and carrying out code scanning test.

Step S118: and judging whether the code scanning test is successful. If the code scanning test fails, go to step S128: the test is stopped, and then step S129 is executed: the test failure was recorded. If the code scanning test is successful, step S119 is executed.

Step S119: the success of the test is recorded. And if the to-be-tested wharf sweeping passes the current test, the light supplementing lamp grating lamp test and the code sweeping test, recording that the test is successful, namely the to-be-tested wharf sweeping passes all PCBA tests.

Step 120: and (5) manually testing. If the automatic test is not started in step S112, the manual test is performed by default. Specifically, the test item may be selected by manually clicking on the software interface manually at step S120. In the embodiment shown in FIG. 4, the listing of test items includes: current testing, light filling lamp grating lamp testing and code scanning testing. If the current test is selected, go to step S121; if the light supplement lamp grating lamp test is selected, executing step S122; if the code scanning test is selected, step S123 is executed.

Step S121: and carrying out a current test.

Step S122: and testing the light supplementing lamp grating lamp.

Step S123: and carrying out code scanning test.

Step S124: after the current test is performed, whether the current test is successful or not is judged in the step, and the test result is recorded.

Step S125: after the light supplementing lamp grating lamp test is carried out, whether the light supplementing lamp grating lamp test is successful or not is judged in the step, and a test result is recorded.

Step S126: after the code scanning test is performed, whether the code scanning test is successful or not is judged in the step, and a test result is recorded.

Step S127: and judging whether all the test items of the manual test are successful. If all the test items are successful, judging that the test is passed, and executing step 119 to record that the test is successful; otherwise, the test is determined to be failed, and step S129 is executed.

In some embodiments, the determination results of steps S124, S125 and S126 are directly sent to step S127, and the determination result of step S127 is no as long as one of the results is failure. In the case of the manual test, it is determined whether all PCBA test items have been executed in step S127, based on the number of determination results received. For example, if the number of PCBA test items is set to 3, in step S127, if 3 test results are received, which indicates that all test items have been manually clicked, it can be determined whether all test items are successful.

Step S128: the test was stopped.

Step S129: the test failure was recorded.

In some embodiments, the success of the logging test of step S119 and the failure of the logging test of step S129 are recorded in the flag corresponding to the PCBA test item in the full test status flag of the dock under test.

According to the embodiment shown in FIG. 4, a PCBA test is considered to have failed whenever the test result of one of the tests is a failure, regardless of the number of test items included in the PCBA test. When all the PCBA test items pass the test, the PCBA test result is passed.

According to the embodiment shown in fig. 4, manual intervention in the testing process is reduced by setting the automatic testing mode; by setting a test mode of manual test, more convenient choices are provided for the wharf sweeping test, and a plurality of test items can be manually and selectively tested; automatic testing and manual testing are combined, and the testing efficiency of the wharf sweeping is improved.

step S21: and acquiring the serial number and the firmware version number of the to-be-tested wharf and acquiring a PCBA test result. The specific contents of the serial number and the firmware version number of the dock to be scanned are obtained in the same step S11, which is not described herein again.

Step S22: if the serial number is successfully acquired, the firmware version number is correct, and the PCBA test result is passed, whether to start the automatic module test is judged. Step S22 is different from step S12 in that: the step requires that the wharf to be tested passes the PCBA test, and if the wharf to be tested does not pass the PCBA test, the module test is not carried out; in addition, the step judges that: the opening module automatically tests. The same parts as those of step S12 will not be described herein again.

Step S23: if the automatic module test is started, the module test items in the module test are automatically executed.

In some embodiments, the modular test items include at least a current test.

In some embodiments, the module test items further include one or any combination of a fill-in light grating light test, a code scanning test, a close-up test and a long-range test.

Step S244: and judging whether all the operations are successful. When all the module test items are successful, the process goes to step S227. Step S227 is the same step as in fig. 6A, and therefore the same reference numerals are used.

If one of all the module test items fails or is unsuccessful, the result of step S244 is no, and the process goes to step S230.

Step S230 and step S231 in fig. 6B are the same steps as step S230 and step S231 in fig. 6A, respectively, and therefore the same reference numerals are used.

Step S251: and (5) carrying out module verification.

To perform this step, a corresponding option is provided on the software interface to select the module verification. By selecting this option, a module verification can be performed. The module verification is the same as the module verification of step S224 in fig. 6A, and will be described in detail later.

Step S252: automatically judging whether the module verification is successful. If yes, go to step S253; if not, go to step S230.

Step S253: and manually judging whether the module verification is successful or not. If yes, go to step S227; if not, go to step S230.

It is understood that, in the manual testing process shown in fig. 6B, the sequence of the test items is not limited.

Fig. 6A and 6B together illustrate one embodiment of a complete detection method. In some embodiments, steps related to module verification, i.e., steps S224, 225, 226, 251, 252, 253, may not be included. In some embodiments, the steps S226 and S253 of manually determining whether the module verification is successful may not be included in the step of module verification.

According to the embodiment of fig. 6A and 6B, the to-be-tested wharf is subjected to the complete test of the PCBA test and the module test, and the obtained test result can be recorded in the complete test status flag of the to-be-tested wharf as the test result of the to-be-tested wharf.

The steps associated with the module verification in fig. 6A and 6B are described below.

In some embodiments of the present invention, after the PCBA test and/or the module test, module verification is also included. And the module verification is used for judging whether the boundary aperture of the grating lamp of the wharf broom to be detected is positioned in the FOV of the camera of the wharf broom to be detected, and if so, the wharf broom to be detected passes the module verification. Specifically, the module verification comprises the following steps: firstly, a to-be-detected wharf scanning operation is executed; specifically, the code scanning operation is executed by enabling the to-be-detected wharf scanning head to face a white background, and a certain preset distance is reserved between the to-be-detected wharf scanning head and the white background; then, when the code scanning operation is executed, the boundary aperture and the center of the grating lamp of the wharf scanner to be detected are obtained, the offset of the center of the scanner to be detected scanner is judged whether the center of the center.

Fig. 7A and 7B are schematic diagrams illustrating a principle of module verification in the detection method according to an embodiment of the invention. Referring to fig. 7A, in performing the module verification, the loading bay to be tested is positioned at a distance of about 15cm from the scan plane 70. The scan plane 70 may be a white background. The scanning operation is performed even if the camera and the raster lamp are simultaneously operated. Referring to FIG. 7B, the camera defines a FOV (field of view) field angle 71 in the scan plane 70 as shown by the outer frame, and the raster lights define a boundary aperture 72 and centroid 73 in the scan plane 70 as shown by the inner frame. In this embodiment, the isocenter 73 is a cross isocenter. In other embodiments, the isocenter 73 may be other shapes.

In the fixed position, the FOV field angle 71 of the camera is fixed, the boundary aperture 72 of the grating lamp is fixed, after the wharf to be detected is imaged, the FOV field angle 71 can be directly used as the size of an imaged picture, and meanwhile, the position of the collimation center 73 in the imaged picture is calculated according to an algorithm, so that whether the boundary aperture 72 of the grating lamp is positioned outside the imaged picture can be calculated. For example, parameters such as the upper margin, the lower margin, the left margin, and the right margin of the boundary aperture 72 from the FOV angle 71 can be calculated.

In some embodiments, the camera of the dock broom to be tested is a camera module. When the camera module of the wharf to be detected and the grating lamp are installed qualified, the boundary apertures 72 are all positioned in the FOV field angle 71; when the camera module and the stop lamp of the dock to be inspected are not properly installed, the boundary aperture 72 may be located outside the FOV angle 71. Through module verification, the abnormal problem of the wharf sweeping assembly to be detected can be detected.

In conjunction with fig. 7A and 7B, the steps S226, S253 of the manual judgment in fig. 6A and 6B include: after the automatic judgment is finished, the FOV image and the grating lamp image are displayed together for the retesting of testers.

In the embodiment shown in fig. 6A and 6B, after the module verification is performed, it is automatically determined whether the module verification is successful according to the algorithm, and manual determination is performed based on the result of the automatic determination, so as to ensure the accuracy of the module verification result.
