Detailed ways

Due to inertia, the position of the refrigerator may deviate when it is running on the production line. When the refrigerator is coded, the fixing device will also tighten the refrigerator, and these external forces will also cause the refrigerator to shift. When people place the refrigerator on the assembly line, it is also easy to cause positional deviation. The refrigerator is relatively large, and it is not easy to detect the positional deviation of a single refrigerator within the visual range of the human eye. These factors will cause the coding position of the refrigerator to shift.

Figure 1 is a schematic diagram of a laser coding system 100 for a refrigerator 160 according to an embodiment of the present invention;

Figure 2 is a flow chart of the control method of the laser coding system 100 of the refrigerator 160 according to one embodiment of the present invention; Figure 3 is a flow chart of the control method of the laser coding system 100 of the refrigerator 160 according to one embodiment of the present invention; FIG. 4 is a block diagram of the laser coding system 100 for the refrigerator 160 according to one embodiment of the present invention; FIG. 5 is a schematic diagram of the laser coding system 100 for the refrigerator 160 according to one embodiment of the present invention.

Based on this, the present invention proposes a laser coding system 100 for a refrigerator 160. The laser coding system 100 for a refrigerator 160 is used to solve the above technical problems. Among them, the laser coding system 100 for the refrigerator 160 includes a position detection device 110, a coder 120, a code scanner 130 and a visual detection device 140. The position detection device 110 is used to detect position-related parameters of the coding position 163 on the refrigerator 160 . In some other embodiments, the position detection device 110 is configured to detect the edge of the refrigerator 160 through translation. Optionally, the position detection device 110 has a 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 detection device 110 is used to detect the edge of the refrigerator 160 based on the reflected laser light.

The specific type of the position detection device 110 can be selected according to needs, such as an image detector, a laser detector or an infrared detector.

The type of the position detection device 110 is a laser detector as an example. At this time, the position detection device 110 is configured to detect the edge of the refrigerator 160 through translation. The laser detector is used to emit laser light, and the laser light is used to detect the edge of the refrigerator 160 . For example, during the translation process of the laser detector, the laser light is always reflected, that is, the laser light cannot pass through the refrigerator 160 , which proves that the refrigerator 160 exists and is not at the edge of the refrigerator 160 . During the translation process of the laser detector, if the laser is not reflected, that is, if the laser passes through, it proves that the location is the edge of the refrigerator 160 . Therefore, the laser detector can detect the edge of the refrigerator 160 during the translation process.

The coder 120 is configured to code to the coding position 163 when the coding position 163 is within the preset area. The position of the coder 120 is set, that is, for the refrigerator 160 of the same model, the position of the coder 120 is fixed. When the refrigerator 160 is coded, if there is no deviation in the position of the refrigerator 160, the coder 120 is facing the coding position 163 on the refrigerator 160. If there is a deviation in the position of the refrigerator 160, the coding position 163 on the refrigerator 160 will also Deviation occurs. At this time, the coder 120 corresponds to other positions of the refrigerator 160. If coding is performed at this time, deviation will occur.

The laser detector takes the coder 120 as the starting point to translate to the edge of the refrigerator 160. Calculate the translation time of the laser detector. According to the translation speed of the laser detector, the product of speed and time is the translation of the coder 120 to the edge of the refrigerator 160. The length is the position-related parameter. Alternatively, the refrigerator 160 laser coding system 100 includes a position sensor. The position sensor is used to detect the displacement of the laser detector from the coder 120 to the edge of the refrigerator 160. The displacement is the translation of the coder 120 to the edge of the refrigerator 160. Length, the length value is the position-related parameter.

The two sides that intersect in the side of the refrigerator 160 where the coding position 163 is located are called the first side 161 and the second side 162 respectively. That is, the first side 161 and the second side 162 are the intersections in the coding surface of the refrigerator 160. of two sides. In this embodiment, as shown in the figure, the first side 161 is the upper edge of the coded surface of the refrigerator 160, and the second side 162 is the left edge of the coded surface of the refrigerator 160. Obviously, the first side 161 and the The two sides 162 can also be the upper edge and the right edge of the surface to be coded.

In this embodiment, the position-related parameters at least include a first translation distance from the coder 120 to the first side 161, and a second translation distance from the coder 120 to the second side 162, so as to fully The orientation measures the deviation of the refrigerator 160 in different directions.

Measure the length value from the coding position 163 on the refrigerator 160 to the first side 161 of the refrigerator 160. The error value can be set to 1 mm. The corresponding threshold range of the first translation distance is the sum of the length value and the error value. Measure the length value from the coding position 163 on the refrigerator 160 to the second side 162 of the refrigerator 160. 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 corresponding threshold range, it is considered that the coding position 163 on the refrigerator 160 is not within the preset area, and it can be determined that the position of the refrigerator 160 is deviated. On the contrary, there is no deviation in the position of refrigerator 160 .

When the laser detector is moving to the edge of the refrigerator 160, it can receive the laser reflected by the refrigerator 160 in real time, so as to obtain the distance between the laser detector and the refrigerator 160 in real time based on the reflected laser. The spacing value can determine whether the coding position 163 on the refrigerator 160 is within the preset area. That is, the spacing value can also determine whether there is any deviation in the coding position 163 on the refrigerator 160 .

The distance, the first translation distance and the second translation distance are combined to accurately determine the offset direction and offset value of the refrigerator 160 . For example, as shown in the figure, when the refrigerator 160 is tilted to the right, the laser detector is in the process of translation to the second side 162 (that is, the left edge of the coded surface of the refrigerator 160). The distance between the laser detector and the refrigerator 160 The value keeps decreasing. Therefore, the distance value alone can detect whether the position of the refrigerator 160 is offset; the distance value combined with the first translation distance and the second translation distance can determine the offset direction of the refrigerator 160 .

The detection principles of infrared detectors and laser detectors are similar and will not be described in detail here.

The image detector is used to obtain the image of the side of the refrigerator 160 where the coding position 163 is located. This image is the position-related parameter. When the position of the refrigerator 160 is not offset, the image of the side plus the error is the threshold range.

In some other embodiments, the coder 120 is configured to code to the coding position 163 when the coding position 163 is within the preset area. The coder 120 is configured to be able to translate; the two intersecting sides on the side of the refrigerator 160 where the coding position 163 is located are called the first side 161 and the second side 162 respectively. The specific type of the coder 120 can be selected according to needs. In this embodiment, the type of the coder 120 is a laser coder 120 . The coder 120 can be moved horizontally to meet the coding needs of different models of refrigerators 160 .

In some other embodiments, the code scanner 130 is used to identify the model identification code of the refrigerator 160, and the visual detection device 140 is used to detect whether the refrigerator 160 has been coded. On the production line of refrigerator 160, there are many models of refrigerator 160, but some models of refrigerator 160 do not require coding. The code scanner 130 is used to obtain the model identification code of the refrigerator 160 to determine whether the refrigerator 160 needs to be coded. This can avoid coding errors and ensure that the refrigerator 160 is coded correctly on the automated assembly line.

In one embodiment, the control method of the laser coding system 100 of the refrigerator 160 includes:

Step S302: Control the position detection device 110 to detect position-related parameters of the coding position 163 on the refrigerator 160.

Based on the above statements, it can be seen that the type of the position detection device 110 can be selected according to needs. The position-related parameters are related to the type of the position detection device 110 and will not be described again here. The location-related parameters are parameters that can reflect the true location of the coding position 163 when the refrigerator 160 is coded. When the refrigerator 160 is coded, the location-related parameters can reflect the true location of the refrigerator 160.

Generally, when the refrigerator 160 is coded, the refrigerator 160 is placed or transported to a designated location, and the coder 120 codes the refrigerator 160 . Taking the assembly line as an example, the refrigerator 160 is transported to the coder 120 on the assembly line, and then coded. Due to inertia or human factors, the true position of the refrigerator 160 when it is coded may shift. If there is a deviation in the position of the refrigerator 160, this will lead to a deviation in the coding position 163 on the refrigerator 160. Therefore, before the refrigerator 160 is coded, the position detection device 110 detects the coding position 163 to avoid coding if there is a deviation in the coding position 163 .

Step S304: Determine whether the coding position 163 is within the preset area according to the position-related parameters.

The specific method of judging the coding position 163 according to the position-related parameters can be selected. In this embodiment, it is judged whether the position-related parameters are within the threshold range. If the position-related parameters are within the threshold range, the coding position 163 is considered to be in the preset position. within the region.

The position-related parameters can reflect the real situation of the coding position 163. If the position-related parameters are no longer within the threshold range, it is considered that the real situation of the coding position 163 is biased. If the location-related parameters are within the preset range, it is considered that there is no deviation from the true situation of the location.

Step S306: If the coding position 163 is not within the preset area, output a reminder signal.

The specific type of the reminder signal is not limited. For example, it can be a voice reminder for code scanning errors, an alarm sound, or the output of relevant subtitles on the display screen. Output a reminder signal to avoid being coded when the coding position 163 deviates.

In one embodiment, the control method of the laser coding system 100 of the refrigerator 160 includes:

Step S302: Control the code scanner 130 to obtain the model identification code of the refrigerator 160.

In this embodiment, the laser coding system 100 for the refrigerator 160 also includes a code scanner 130 , and the code scanner 130 is used to identify the model identification code of the refrigerator 160 . The specific type of model identification code can be selected according to needs, such as bar code or QR code. The model identification code at least includes model information of the refrigerator 160 , and the model information at least includes the size of the refrigerator 160 . Different models of refrigerators 160 have different sizes, different coding positions 163 on the refrigerators 160 , and different coding patterns on the refrigerators 160 . Some refrigerators 160 may not require coding. Therefore, obtaining the model identification code of the refrigerator 160 can avoid incorrect coding and achieve automated and correct coding of multiple models of refrigerators 160 .

Step S304: If the code scanner 130 cannot recognize the model identification code, output a reminder signal.

The specific type of the reminder signal is not limited. For example, it can be a voice reminder for code scanning errors, an alarm sound, or the output of relevant subtitles on the display screen. The code scanner 130 cannot recognize the model identification code and outputs a reminder signal to alert the user of abnormal code scanning, reminding people to find the problem and avoid missing scans.

Step S306: Determine whether the refrigerator 160 needs to be coded based on the model information of the refrigerator 160.

In this embodiment, the laser coding system 100 for the refrigerator 160 also includes a transport device 170, which is used to transport the completely coded refrigerator 160 to a designated location.

The model information may include whether the refrigerator 160 needs to be coded, or it may be determined based on the model information whether the refrigerator 160 needs to be coded. The specific pattern for coding the refrigerator 160 is not limited. For example, the coding pattern can be the logo of the refrigerator 160. Different refrigerator 160 models may have different logos, and some refrigerators 160 may not require a logo. This step can avoid coding the refrigerator 160 that does not need to be coded, and can also avoid the logo on the refrigerator 160 being different from its model.

In some other embodiments, this step also includes, if the refrigerator 160 does not need to be coded, directly controlling the transport device 170 to transport the refrigerator 160 to the next work station. This can avoid repeated coding of the refrigerator 160 and at the same time give the coding position 163 to the refrigerator 160 that needs to be coded.

Step S308: If the refrigerator 160 needs to be coded, control the visual detection device 140 to detect whether the refrigerator 160 has been coded.

The laser coding system 100 for the refrigerator 160 also includes a visual detection device 140. The visual detection device 140 is used to detect whether the refrigerator 160 has been coded. This ensures that the coding step is only performed when there is no coding, thus avoiding repeated coding and missed coding.

Step S310: If the refrigerator 160 has been coded, determine whether the code is correct based on the model identification code of the refrigerator 160.

The model identification code of the refrigerator 160 corresponds to the coding pattern. This step can avoid incorrect coding.

In some other embodiments, this step also includes, if the coding is correct, directly controlling the transport device 170 to transport the refrigerator 160 to the next work station. This can avoid repeated coding of the refrigerator 160 and at the same time give the coding position 163 to the refrigerator 160 that needs to be coded.

Step S312: If the coding is incorrect, output a reminder signal.

The specific type of the reminder signal is not limited. For example, it can be a voice reminder for coding errors, an alarm sound, or the output of relevant subtitles on the display screen. If the coding is incorrect, this will remind you to correct it in time to avoid erroneous coding.

In some other embodiments, this step also includes, if the coding is correct, directly controlling the transport device 170 to transport the refrigerator 160 to the next work station. This can avoid repeated coding of the refrigerator 160 and at the same time give the coding position 163 to the refrigerator 160 that needs to be coded.

Step S314: If there is no coding on the refrigerator 160, control the position detection device 110 to detect the position-related parameters of the coding position 163 on the refrigerator 160.

Based on the above statements, it can be seen that the type of the position detection device 110 can be selected according to needs. The position-related parameters are related to the type of the position detection device 110 and will not be described again here. The location-related parameters are parameters that can reflect the true location of the coding position 163 when the refrigerator 160 is coded. When the refrigerator 160 is coded, the location-related parameters can reflect the true location of the refrigerator 160. Therefore, before the refrigerator 160 is coded, the position detection device 110 detects the coding position 163 to avoid coding if there is a deviation in the coding position 163 .

In some embodiments, the position detection device 110 is configured to detect the edge of the refrigerator 160 through translation; the laser coding system 100 of the refrigerator 160 further includes a coder 120, and the coder 120 is configured to detect the edge of the refrigerator 160 at a preset coding position 163. When within the area, code is printed toward the coding position 163; the two intersecting sides on the side of the refrigerator 160 where the coding position 163 is located are called the first side 161 and the second side 162 respectively.

The step of controlling the position detection device 110 to detect position-related parameters of the coding position 163 on the refrigerator 160 includes: controlling the position detection device 110 to translate from the coder 120 to the first side 161 and obtaining the first translation distance of the position detection device 110; Control the position detection device 110 to translate from the coder 120 to the second side 162 and obtain the second translation distance of the position detection device 110; the position-related parameters include the first translation distance and the second translation distance.

In this embodiment, the type of detection device may be a laser detector or an infrared detector,

In some embodiments, when the position detection device 110 has a 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 detection device 110 is used to detect the edge of the refrigerator 160 based on the reflected laser light.

The step of controlling the position detection device 110 to detect the position-related parameters of the coding position 163 on the refrigerator 160 also includes: during the translation process of the position detection device 110, calculating the distance between the refrigerator 160 and the position detection device 110 during the translation process based on the received reflected laser. ;Position-related parameters also include spacing.

The coder 120 is configured to code to the coding position 163 when the coding position 163 is within the preset area. The position of the coder 120 is set, that is, for the refrigerator 160 of the same model, the position of the coder 120 is fixed. When the refrigerator 160 is coded, if there is no deviation in the position of the refrigerator 160, the coder 120 is facing the coding position 163 on the refrigerator 160. If there is a deviation in the position of the refrigerator 160, the coding position 163 on the refrigerator 160 will also Deviation occurs. At this time, the coder 120 corresponds to other positions of the refrigerator 160. If coding is performed at this time, deviation will occur.

The laser detector takes the coder 120 as the starting point to translate to the edge of the refrigerator 160. Calculate the translation time of the laser detector. According to the translation speed of the laser detector, the product of speed and time is the translation of the coder 120 to the edge of the refrigerator 160. The length is the position-related parameter. Alternatively, the refrigerator 160 laser coding system 100 includes a position sensor. The position sensor is used to detect the displacement of the laser detector from the coder 120 to the edge of the refrigerator 160. The displacement is the translation of the coder 120 to the edge of the refrigerator 160. Length, the length value is the position-related parameter.

The two sides that intersect in the side of the refrigerator 160 where the coding position 163 is located are called the first side 161 and the second side 162 respectively. That is, the first side 161 and the second side 162 are the intersections in the coding surface of the refrigerator 160. of two sides. In this embodiment, as shown in the figure, the first side 161 is the upper edge of the coded surface of the refrigerator 160, and the second side 162 is the left edge of the coded surface of the refrigerator 160. Obviously, the first side 161 and the The two sides 162 can also be the upper edge and the right edge of the surface to be coded.

In this embodiment, the position-related parameters at least include a first translation distance from the coder 120 to the first side 161, and a second translation distance from the coder 120 to the second side 162, so as to fully The orientation measures the deviation of the refrigerator 160 in different directions.

When the laser detector is moving to the edge of the refrigerator 160, it can receive the laser reflected by the refrigerator 160 in real time, so as to obtain the distance between the laser detector and the refrigerator 160 in real time based on the reflected laser. This spacing can determine whether the coding position 163 on the refrigerator 160 is within the preset area. That is, this spacing can also determine whether there is any deviation in the coding position 163 on the refrigerator 160 .

The distance, the first translation distance and the second translation distance are combined to accurately determine the offset direction and offset value of the refrigerator 160 . For example, as shown in the figure, when the refrigerator 160 is tilted to the right, the laser detector is in the process of translation to the second side 162 (that is, the left edge of the coded surface of the refrigerator 160). The distance between the laser detector and the refrigerator 160 The value keeps decreasing. Therefore, the distance value alone can detect whether the position of the refrigerator 160 is offset; the distance value combined with the first translation distance and the second translation distance can determine the offset direction of the refrigerator 160 .

The laser coding system 100 for the refrigerator 160 includes a position detection device 110 . The position detection device 110 is used to detect position-related parameters of the coding position 163 on the refrigerator 160 . The parameters related to the detection position reflect the actual situation of the coding position 163, which can avoid deviations in the coding of the refrigerator 160 and cause inconsistency in the coding of the refrigerator 160.

Step S316: Determine the offset direction of the coding position 163 according to the position-related parameters 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 offset value of the refrigerator 160 . For example, as shown in the figure, when the refrigerator 160 shifts to the right or left, the second translation distance can only show that the refrigerator 160 shifts to the left or right, but cannot determine the specific direction. However, when the laser detector is moving to the second side 162 (that is, the left edge of the coded surface of the refrigerator 160), if the distance between the laser detector and the refrigerator 160 continues to decrease, it proves that it is deflected to the right. Shift, if the spacing value continues to become larger, it proves to be shifted to the left. Therefore, the distance value alone can detect whether the position of the refrigerator 160 is offset; the distance value combined 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 Investigate the cause.

Step S318: Determine whether the coding position 163 is within the preset area according to the position-related parameters.

The specific method of judging the coding position 163 according to the position-related parameters can be selected. In this embodiment, it is judged whether the position-related parameters are within the threshold range. If the position-related parameters are within the threshold range, the coding position 163 is considered to be in the preset position. within the region. The threshold range is related to the specific type of the position-related parameter, for example, if the position-related parameter is an image, the threshold range is also an image; if the position-related parameter is a numeric value, the threshold range is also a numeric value.

If the position detection 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 parameters includes: comparing the first translation distance, the second translation distance and the spacing with the corresponding threshold range; if If the first translation distance or the second translation distance or spacing exceeds the corresponding threshold range, it is considered that the coding position 163 is not within the preset area.

Measure the length value from the coding position 163 on the refrigerator 160 to the first side 161 of the refrigerator 160. The error value is generally set to 1 mm. The corresponding threshold range of the first translation distance is the sum of the length value and the error value. The length value of the coding 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 corresponding threshold range, it is considered that the coding position 163 on the refrigerator 160 is not within the preset area, and it can be determined that the position of the refrigerator 160 is deviated. On the contrary, there is no deviation in the position of refrigerator 160 . Taking the coded surface of the refrigerator 160 as a plane as an example, if there is no deviation in the position of the refrigerator 160, the sum of the distance between the coder 120 and the coding position 163 and the error value is the threshold range corresponding to the distance. If the distance does not Within the threshold range corresponding to the distance, it is considered that the coding position 163 on the refrigerator 160 is not within the preset area.

The position-related parameters can reflect the real situation of the coding position 163. If the position-related parameters are no longer within the threshold range, it is considered that the real situation of the coding position 163 is biased. If the location-related parameters are within the preset range, it is considered that there is no deviation from the true situation of the location.

Step S320: If the coding position 163 is not within the preset area, output a reminder signal

When the coding position 163 is not within the preset range, a reminder signal is output to prevent the refrigerator 160 from being coded when the position deviates, resulting in coding tilt.

Step S322: If the coding position 163 is within the preset area, control the coding device 120 to code.
