Detailed Description
Due to inertia, the refrigerator may deviate in position when the refrigerator is operated on a production line. When the refrigerator is coded, the refrigerator can be clamped by the fixing device, and the refrigerator can be offset due to the external force. When people put the refrigerator on the assembly line, the position deviation is easy to be caused, the refrigerator is large in size, and the position deviation of a single refrigerator is not easy to be perceived in the visual range of eyes of people. These factors can lead to deviations in the coding position of the refrigerator.

fig. 2 is a flowchart of a control method of the laser coding system 100 of the refrigerator 160 according to an embodiment of the present invention; fig. 3 is a flowchart of a control method of the laser coding system 100 of the refrigerator 160 according to an embodiment of the present invention; fig. 4 is a block diagram of the refrigerator 160 laser coding system 100 according to one embodiment of the present invention; fig. 5 is a schematic diagram of a refrigerator 160 laser coding system 100 according to one embodiment of the invention.
Based on this, the present invention proposes a laser coding system 100 of a refrigerator 160, and the laser coding system 100 of the refrigerator 160 is used for solving the above technical problems. The refrigerator 160 laser coding system 100 includes a position detecting device 110, a coding device 120, a code scanner 130 and a visual detecting device 140. The position detecting device 110 is used for detecting a position-related parameter of the coding position 163 on the refrigerator 160. In other embodiments, the position detection device 110 is configured to detect an edge of the refrigerator 160 by translation. Alternatively, the position detecting device 110 has a laser 111, the laser 111 is used for emitting laser light to the refrigerator 160, the refrigerator 160 is used for reflecting the laser light, and the position detecting device 110 is used for detecting edges of the refrigerator 160 according to the reflected laser light.
The specific type of position detection device 110 may be selected as desired, such as an image detector, a laser detector, or an infrared detector.
The type of position detection device 110 is exemplified by a laser detector, at which time the position detection device 110 is configured to detect an edge of the refrigerator 160 by translation. The laser detector is used to emit laser light for detecting edges of the refrigerator 160. For example, if the laser detector is constantly being reflected during translation, i.e., the laser cannot pass through the refrigerator 160, it is demonstrated that the refrigerator 160 is present, where it is not a refrigerator 160 edge. During translation, the laser light is not reflected, i.e., the laser light passes through, which is evidenced by the edges of the refrigerator 160. Thus, the laser detector can detect edges of the refrigerator 160 during translation.
The code printer 120 is configured to code the code printing position 163 when the code printing position 163 is within a preset area range. The position of the code printer 120 is set, i.e., the position of the code printer 120 is fixed for the same type of refrigerator 160. When the refrigerator 160 is coded, if the position of the refrigerator 160 does not deviate, the code printer 120 is opposite to the code printing position 163 on the refrigerator 160, if the position of the refrigerator 160 deviates, the code printing position 163 on the refrigerator 160 also deviates, at this time, the code printer 120 corresponds to other positions of the refrigerator 160, and if the code is printed, the deviation occurs.
And (3) calculating the translation time of the laser detector in the process of translating the laser detector to the edge of the refrigerator 160 by taking the code printer 120 as a starting point, wherein the product of the speed and the time is the length of the translation of the code printer 120 to the edge of the refrigerator 160 according to the translation speed of the laser detector, and the length value is the position-related parameter. Alternatively, the laser coding system 100 of the refrigerator 160 includes a position sensor, where the position sensor is configured to detect a displacement of the laser detector from the position of the coder 120 to the edge of the refrigerator 160, where the displacement is a length of the translation of the coder 120 to the edge of the refrigerator 160, and the length value is a position-related parameter.
The two sides intersecting in the side of the refrigerator 160 where the coding position 163 is located are referred to as a first side 161 and a second side 162, respectively, i.e., the first side 161 and the second side 162 are the two sides intersecting in the coded surface of the refrigerator 160. In this embodiment, as shown in the drawing, the first edge 161 is the upper edge of the coded surface of the refrigerator 160, and the second edge 162 is the left edge of the coded surface of the refrigerator 160, and it is obvious that the first edge 161 and the second edge 162 may also be the upper edge and the right edge of the coded surface.
In the present embodiment, the position-related parameters include at least a first translation distance from the encoder 120 to the first side 161 and a second translation distance from the encoder 120 to the second side 162, so as to measure the deviation of the refrigerator 160 in all directions.
The length value of the code printing position 163 on the refrigerator 160 from the first edge 161 of the refrigerator 160 is measured, the error value can be set to 1 millimeter, and the threshold range corresponding to the first translation distance is the sum of the length value and the error value. The length value of the code position 163 on the refrigerator 160 from the second edge 162 of the refrigerator 160 is measured, and the threshold range corresponding to the second translation distance is the sum of the length value and the error value. If the first translation distance or the second translation distance does not fall within the threshold range corresponding thereto, the code printing position 163 on the refrigerator 160 is not considered to be within the preset area range, and the deviation of the position of the refrigerator 160 can be considered. Otherwise, no deviation is generated in the position of the refrigerator 160.
The laser detector can receive the laser reflected by the refrigerator 160 in real time in the process of translating to the edge of the refrigerator 160, and is used for acquiring the distance between the laser detector and the refrigerator 160 in real time according to the reflected laser. The distance value can determine whether the code printing position 163 on the refrigerator 160 is within a preset area range, that is, the distance value can also determine whether the code printing position 163 on the refrigerator 160 has deviation.
The distance, the first translation distance, and the second translation distance are combined to accurately determine the offset direction and the offset value of the refrigerator 160. For example, as the refrigerator 160 is deflected to the right as shown, the distance value of the laser detector from the refrigerator 160 decreases as the laser detector translates to the second edge 162 (i.e., the left edge of the coded surface of the refrigerator 160). Accordingly, the separate interval value can detect whether the position of the refrigerator 160 is shifted; the distance value in combination with the first translation distance and the second translation distance can determine the direction of the offset of the refrigerator 160.
The detection principle of the infrared detector is similar to that of the laser detector, and the detection principle is not repeated here.
The image detector is used for acquiring an image of the side face of the refrigerator 160 where the coding position 163 is located, the image is a position-related parameter, and when the position of the refrigerator 160 is not deviated, the image of the side face plus an error is a threshold range.
In other embodiments, the code printer 120 is configured to code the code location 163 when the code location 163 is within the predetermined area. The code printer 120 is configured to be translatable; the two sides intersecting in the side of the refrigerator 160 where the coding position 163 is located are referred to as a first side 161 and a second side 162, respectively. The specific type of the encoder 120 may be selected as desired, and in this embodiment, the type of the encoder 120 is a laser encoder 120. The code printer 120 can translate to meet the code printing of different types of refrigerators 160.
In other embodiments, the code scanner 130 is configured to identify a model identification code of the refrigerator 160, and the visual detection device 140 is configured to detect whether the refrigerator 160 has been coded. In the production line of the refrigerator 160, there are various models of the refrigerator 160, but some models of the refrigerator 160 do not need coding. The code scanner 130 is configured to obtain a model identification code of the refrigerator 160, so as to determine whether the refrigerator 160 needs to be coded, which can avoid coding errors and ensure correct coding of the refrigerator 160 on an automated assembly line.
In one embodiment, the control method of the refrigerator 160 laser coding system 100 includes:
step S302: the control position detecting device 110 detects a position-related parameter of the code printing position 163 on the refrigerator 160.
Based on the above description, the type of the position detecting device 110 can be selected as required, and the position-related parameter is related to the type of the position detecting device 110, which is not described herein. The position-related parameter is a parameter that reflects the true position of the coding position 163 when the refrigerator 160 is coded, and reflects the true position of the refrigerator 160 when the refrigerator 160 is coded.
Generally, when the refrigerator 160 is coded, the refrigerator 160 is put or transported to a designated location, and the code printer 120 codes the refrigerator 160. Taking the pipeline as an example, the refrigerator 160 is transported to the encoder 120 on the pipeline and then encoded. The actual position of the refrigerator 160 when coded may shift due to inertia or human factors. If there is a deviation in the position of the refrigerator 160, this will result in a deviation in the coding position 163 on the refrigerator 160. Therefore, the position detecting device 110 detects the code position 163 before the refrigerator 160 is coded, so as to avoid being coded in the case that the code position 163 is deviated.
Step S304: whether the coding position 163 is within the preset area is judged according to the position-related parameters.
The specific manner of determining the coding position 163 according to the position-related parameter may be selected, and in this embodiment, whether the position-related parameter is within the threshold range is determined, and if the position-related parameter is within the threshold range, the coding position 163 is considered to be within the preset area range.
The position-related parameter can reflect the true condition of the coding position 163, and if the position-related parameter is no longer within the threshold range, the true condition of the coding position 163 is considered to have a deviation. If the position-related parameter is within the preset range, the true situation of the position is considered to have no deviation.
Step S306: if the code printing position 163 is not within the preset area range, a reminding signal is output.
The specific type of the reminding signal is not limited, and for example, the reminding signal can be a voice reminding code scanning error, an alarm sound or a related caption output on a display screen. The output alert signal prevents the code position 163 from being coded when it is biased.
In one embodiment, the control method of the refrigerator 160 laser coding system 100 includes:
step S302: the code scanner 130 is controlled to acquire the model identification code of the refrigerator 160.
In this embodiment, the laser coding system 100 of the refrigerator 160 further includes a code scanner 130, where the code scanner 130 is used to identify the model identification code of the refrigerator 160. The specific type of the model identification code can be selected according to the needs, such as a bar code or a two-dimensional code. The model identification code includes at least model information of the refrigerator 160, which includes at least the size of the refrigerator 160. Different types of refrigerators 160, different sizes of refrigerators 160, different coding positions 163 of the refrigerators 160, different coding patterns of the refrigerators 160, and some refrigerators 160 may not need coding. Therefore, obtaining the model identification code of the refrigerator 160 may avoid coding error codes to achieve automatic, correct coding of the multi-model refrigerator 160.
Step S304: if the code scanner 130 cannot recognize the model identification code, a reminding signal is output.
The specific type of the reminding signal is not limited, and for example, the reminding signal can be a voice reminding code scanning error, an alarm sound or a related caption output on a display screen. The code scanner 130 cannot recognize the model identification code, and outputs a reminding signal to remind the person of abnormal code scanning, so that the person is reminded of finding the problem and the missing scanning is avoided.
Step S306: whether the refrigerator 160 needs coding is judged according to the model information of the refrigerator 160.
In this embodiment, the laser coding system 100 of the refrigerator 160 further includes a transporting device 170, where the transporting device 170 is used to transport the coded complete refrigerator 160 to a specified location.
The model information may include whether the refrigerator 160 needs to be coded, or whether the refrigerator needs to be coded may be determined according to the model information. The specific pattern of the coding of the refrigerator 160 is not limited, for example, the coding pattern may be a logo of the refrigerator 160, different types of the refrigerator 160 may be different, and some refrigerators 160 may not need a logo. The step can avoid coding the refrigerator 160 without coding, and can also avoid that the logo on the refrigerator 160 is different from the model of the refrigerator 160.
In other embodiments, this step may be followed by controlling the transport device 170 to transport the refrigerator 160 to the next station if the refrigerator 160 does not need to be coded. This can avoid the refrigerator 160 from repeating the coding while giving the coding position 163 to the refrigerator 160 requiring coding.
Step S308: if the refrigerator 160 needs to be coded, the visual detection device 140 is controlled to detect whether the refrigerator 160 is coded.
The laser coding system 100 of the refrigerator 160 further includes a visual detection device 140, where the visual detection device 140 is configured to detect whether the refrigerator 160 has been coded. This ensures that the coding step is performed without coding, so that repeated coding and missing coding can be avoided.
Step S310: if the code is already printed on the refrigerator 160, whether the code is correct is judged according to the model identification code of the refrigerator 160.
The refrigerator 160 has a model identification code corresponding to the code pattern, and this step can avoid the error code.
In other embodiments, this step may be followed by controlling the transport device 170 to transport the refrigerator 160 to the next station if the code is correct. This can avoid the refrigerator 160 from repeating the coding while giving the coding position 163 to the refrigerator 160 requiring coding.
Step S312: if the code is incorrect, outputting a reminding signal.
The specific type of the reminding signal is not limited, and for example, the reminding signal can be a voice reminding code-coding error, an alarm sound or a related caption output on a display screen. If the code is incorrect, the prompt is corrected in time, and error code printing is avoided.
In other embodiments, this step may be followed by controlling the transport device 170 to transport the refrigerator 160 to the next station if the code is correct. This can avoid the refrigerator 160 from repeating the coding while giving the coding position 163 to the refrigerator 160 requiring coding.
Step S314: if the refrigerator 160 is not coded, the control position detecting device 110 detects the position-related parameter of the coding position 163 on the refrigerator 160.
Based on the above description, the type of the position detecting device 110 can be selected as required, and the position-related parameter is related to the type of the position detecting device 110, which is not described herein. The position-related parameter is a parameter that reflects the true position of the coding position 163 when the refrigerator 160 is coded, and reflects the true position of the refrigerator 160 when the refrigerator 160 is coded. Therefore, the position detecting device 110 detects the code position 163 before the refrigerator 160 is coded, so as to avoid being coded in the case that the code position 163 is deviated.
In some embodiments, the position detection device 110 is configured to detect an edge of the refrigerator 160 by translation; the refrigerator 160 laser coding system 100 further includes a coding device 120, the coding device 120 being configured to code the coding position 163 when the coding position 163 is within a preset area; the two sides intersecting in the side of the refrigerator 160 where the coding position 163 is located are referred to as a first side 161 and a second side 162, respectively.
The step of controlling the position detecting device 110 to detect the position-related parameter of the code printing position 163 on the refrigerator 160 includes: controlling the position detecting device 110 to translate from the encoder 120 to the first side 161 and acquiring a first translation distance of the position detecting device 110; controlling the position detecting device 110 to translate from the encoder 120 to the second side 162 and obtaining a second translation distance of the position detecting device 110; the position-related parameter includes a first translation distance and a second translation distance.
In this embodiment, the type of detection means may be a laser detector or an infrared detector,
in some embodiments, when the position detecting device 110 has the laser 111, the laser 111 is used to emit laser light to the refrigerator 160, the refrigerator 160 is used to reflect the laser light, and the position detecting device 110 is used to detect edges of the refrigerator 160 according to the reflected laser light.
The step of controlling the position detecting device 110 to detect the position-related parameter of the code printing position 163 on the refrigerator 160 further includes: in the translation process of the position detection device 110, calculating the distance between the refrigerator 160 and the position detection device 110 in the translation process according to the received reflected laser; the location-related parameters also include spacing.
The code printer 120 is configured to code the code printing position 163 when the code printing position 163 is within a preset area range. The position of the code printer 120 is set, i.e., the position of the code printer 120 is fixed for the same type of refrigerator 160. When the refrigerator 160 is coded, if the position of the refrigerator 160 does not deviate, the code printer 120 is opposite to the code printing position 163 on the refrigerator 160, if the position of the refrigerator 160 deviates, the code printing position 163 on the refrigerator 160 also deviates, at this time, the code printer 120 corresponds to other positions of the refrigerator 160, and if the code is printed, the deviation occurs.
And (3) calculating the translation time of the laser detector in the process of translating the laser detector to the edge of the refrigerator 160 by taking the code printer 120 as a starting point, wherein the product of the speed and the time is the length of the translation of the code printer 120 to the edge of the refrigerator 160 according to the translation speed of the laser detector, and the length value is the position-related parameter. Alternatively, the laser coding system 100 of the refrigerator 160 includes a position sensor, where the position sensor is configured to detect a displacement of the laser detector from the position of the coder 120 to the edge of the refrigerator 160, where the displacement is a length of the translation of the coder 120 to the edge of the refrigerator 160, and the length value is a position-related parameter.
The two sides intersecting in the side of the refrigerator 160 where the coding position 163 is located are referred to as a first side 161 and a second side 162, respectively, i.e., the first side 161 and the second side 162 are the two sides intersecting in the coded surface of the refrigerator 160. In this embodiment, as shown in the drawing, the first edge 161 is the upper edge of the coded surface of the refrigerator 160, and the second edge 162 is the left edge of the coded surface of the refrigerator 160, and it is obvious that the first edge 161 and the second edge 162 may also be the upper edge and the right edge of the coded surface.
In the present embodiment, the position-related parameters include at least a first translation distance from the encoder 120 to the first side 161 and a second translation distance from the encoder 120 to the second side 162, so as to measure the deviation of the refrigerator 160 in all directions.
The laser detector can receive the laser reflected by the refrigerator 160 in real time in the process of translating to the edge of the refrigerator 160, and is used for acquiring the distance between the laser detector and the refrigerator 160 in real time according to the reflected laser. The interval can determine whether the code printing position 163 on the refrigerator 160 is within a preset area, that is, the interval can also determine whether the code printing position 163 on the refrigerator 160 has deviation.
The distance, the first translation distance, and the second translation distance are combined to accurately determine the offset direction and the offset value of the refrigerator 160. For example, as the refrigerator 160 is deflected to the right as shown, the distance value of the laser detector from the refrigerator 160 decreases as the laser detector translates to the second edge 162 (i.e., the left edge of the coded surface of the refrigerator 160). Accordingly, the separate interval value can detect whether the position of the refrigerator 160 is shifted; the distance value in combination with the first translation distance and the second translation distance can determine the direction of the offset of the refrigerator 160.
The laser coding system 100 of the refrigerator 160 includes a position detecting device 110, and the position detecting device 110 is used for detecting a position-related parameter of a coding position 163 on the refrigerator 160. The detection position-related parameter reflects the real situation of the coding position 163, which can avoid the deviation of the refrigerator 160 when coding, and the inconsistency of coding of the refrigerator 160 is caused.
Step S316: the direction in which the coding position 163 is shifted is determined according to the position-related parameter and the corresponding threshold range.
The distance, the first translation distance, and the second translation distance are combined to accurately determine the offset direction and the offset value of the refrigerator 160. For example, when the refrigerator 160 is shifted to the right or left as shown, the second shift distance can only indicate that the refrigerator 160 is shifted to the left or right, and a specific direction cannot be determined. However, during translation of the laser detector to the second edge 162 (i.e., the left edge of the coded surface of the refrigerator 160), if the distance value of the laser detector from the refrigerator 160 is decreasing, it is proved to be shifted to the right, and if the distance value is increasing, it is proved to be shifted to the left. Accordingly, the separate interval value can detect whether the position of the refrigerator 160 is shifted; the distance value, in combination with the first translation distance and the second translation distance, can determine the offset direction of the refrigerator 160, which is helpful for calibrating the position of the refrigerator 160 and checking the reason.
Step S318: whether the coding position 163 is within the preset area is judged according to the position-related parameters.
The specific manner of determining the coding position 163 according to the position-related parameter may be selected, and in this embodiment, whether the position-related parameter is within the threshold range is determined, and if the position-related parameter is within the threshold range, the coding position 163 is considered to be within the preset area range. The threshold range is associated with a particular type of location-related parameter, e.g., if the location-related parameter is an image, then the threshold range is also an image; if the position-related parameter is a numerical value, the threshold range is also a numerical value.
If the position detecting device 110 is a laser type, the step of determining whether the coding position 163 is within the preset area according to the position-related parameter includes: comparing the first translation distance, the second translation distance and the spacing with corresponding threshold ranges respectively; if the first translation distance or the second translation distance or the distance exceeds the corresponding threshold range, the coding position 163 is not considered to be within the preset area range.
The length value of the code printing position 163 on the refrigerator 160 from the first edge 161 of the refrigerator 160 is measured, the error value is generally set to 1 mm, and the threshold range corresponding to the first translation distance is the sum of the length value and the error value. The length value of the code position 163 on the refrigerator 160 from the second side 162 of the refrigerator 160 is measured, and the threshold range corresponding to the second translation distance is the sum of the length value and the error value. If the first translation distance or the second translation distance does not fall within the threshold range corresponding thereto, the code printing position 163 on the refrigerator 160 is not considered to be within the preset area range, and the deviation of the position of the refrigerator 160 can be considered. Otherwise, no deviation is generated in the position of the refrigerator 160. Taking the coded surface of the refrigerator 160 as a plane as an example, in the case that the position of the refrigerator 160 has no deviation, the sum of the distance between the code encoder 120 and the code printing position 163 and the error value is the threshold range corresponding to the distance, and if the distance is not within the threshold range corresponding to the distance, the code printing position 163 on the refrigerator 160 is not considered to be within the preset area range.
The position-related parameter can reflect the true condition of the coding position 163, and if the position-related parameter is no longer within the threshold range, the true condition of the coding position 163 is considered to have a deviation. If the position-related parameter is within the preset range, the true situation of the position is considered to have no deviation.
Step S320: if the code printing position 163 is not within the preset area range, a reminding signal is output
When the code printing position 163 is not within the preset range, a reminding signal is output, so that the refrigerator 160 is prevented from being code printed when the position is deviated, and the code printing inclination is avoided.
Step S322: if the coding position 163 is within the preset area, the coding device 120 is controlled to code.
Step S324: the transport device 170 is controlled to transport the refrigerator 160 to the next station.
In this embodiment, the laser coding system 100 of the refrigerator 160 further includes a transporting device 170, where the transporting device 170 is used to transport the coded complete refrigerator 160 to a specified location. This step transports the coded refrigerator 160 to the next station, giving up the coding position 163 to the refrigerator 160 requiring coding.
