Detailed Description
Referring to fig. 1 to 4, the detection device 10 is used for detecting the thickness of an inner container 90 of a refrigerating and freezing device, and specifically, the thickness of the inner container 90 includes the thickness of one wall 91 of the inner container 90.
The detection device 10 may generally include a laser rangefinder 20, a transmission unit 40, and a control unit 51. The number of the laser range finders 20 is at least two, and two of the laser range finders 20 are arranged so that their respective laser detection heads 201 are opposed. The transfer unit 40 is disposed between the two laser rangefinders 20 to transfer the liner 90 between the two laser rangefinders 20 and to position the liner 90 between the two laser rangefinders 20. The control unit 51 is configured to control the transfer unit 40 to transfer the liner 90, and to control the two laser rangefinders 20 to detect their respective distances from one wall 91 of the liner 90. The broken lines in fig. 1 represent the laser light emitted by the two laser rangefinders 20, and the broken line arrows in fig. 1 and 3 represent the conveying direction of the liner 90.
That is, the detection device 10 has two laser distance meters 20 disposed opposite to each other, and the two laser distance meters 20 respectively detect the distances (distance a and distance B) from one wall 91 of the inner container 90 to be detected. Thus, a thickness value of the one wall 91 of the inner container 90 to be measured can be obtained by subtracting the distance a and the distance B from the total distance C between the two laser distance meters 20. The inner container 90 may be transferred between the two laser rangefinders 20 through the transfer unit 40 and positioned between the two laser rangefinders 20, and the positioned position may be a position to be measured. When the inner container 90 is positioned at a position to be measured, the two laser range finders 20 perform detection to obtain the thickness value of the wall 91 of the inner container 90 at the position. Subsequently, the inner container 90 may be transferred to the outside of the two laser rangefinders 20 by the transfer unit 40 for assembly or other operations, or the inner container 90 may also be transferred to another position to be measured between the two laser rangefinders 20 by the transfer unit 40, and thickness detection of the inner container 90 may be performed again to obtain a plurality of detection data.
The utility model discloses a detection device 10 conveys inner bag 90 to carrying out the thickness detection between two laser range finder 20 through transfer unit 40 to leave two laser range finder 20 with its conveying after this inner bag 90 is surveyed. Therefore, the liner 90 does not need to be damaged, manually transported and manually detected, and the detection efficiency of the detection device 10 is improved.
Further, the utility model discloses a detection device 10 carries out a lot of detections with inner bag 90 location in a plurality of positions to be measured through transfer unit 40, can acquire a plurality of thickness values, has further improved detection device 10's detection efficiency.
Referring to fig. 1-3 and 5, in some embodiments, the detection device 10 further includes a carriage unit 70 and a drive unit 80. Specifically, the laser range finder 20 is movably provided to the holder unit 70. The driving unit 80 is configured to drive the laser rangefinder 20 to move so as to detect thickness values of different positions of one wall 91 of the liner 90 by two oppositely disposed laser rangefinders 20.
That is, the detection device 10 of the present invention moves the laser range finder 20 relative to the inner container 90 positioned in the transmission unit through the driving unit 80 to obtain a plurality of detection data. This further improves the detection efficiency of the detection device 10.
In some embodiments, referring to fig. 1, 2 and 5, the stand unit 70 includes one support bar 72 and two adjustment bars 71. The adjustment rods 71 are disposed on the support rod 72 in parallel and at intervals, and the two laser range finders 20 disposed opposite to each other are disposed on the two adjustment rods 71, respectively. Further, each adjusting rod 71 and the supporting rod 72 are perpendicularly arranged, and the plane where the two adjusting rods 71 and the supporting rod 72 intersect is perpendicular to the conveying plane 42 of the conveying unit 40 for conveying the liner 90.
That is, the driving unit may adjust the position of the inner container 90 with respect to the laser range finder 20 in the conveying direction, and the adjusting lever 71 may adjust the position of the laser range finder 20 with respect to the inner container 90 in the direction perpendicular to the conveying direction in parallel to the conveying plane 42. Thus, the laser range finder 20 can move in any direction in the plane of the wall 91 of the inner container 90 (i.e., the conveying plane 42), and can detect the thickness of the wall 91 at any position.
Since the inner container 90 of the refrigerating and freezing device (such as a refrigerator, an ice chest, etc.) has a large volume and a surface with a large number of rugged designs, when the thickness of the object to be measured with a special structure, such as the inner container 90, is detected, the thickness detection only on a single position cannot obtain the information of the whole thickness of the inner container 90. And the thickness values of a plurality of positions of the inner container 90 are obtained only by moving the inner container, so that a complex transmission mechanism is required, and the large-size object to be detected is not convenient to quickly position. Thus, the detection device 10 is advantageous for the detection device 10 for detecting the thickness of the wall 91 of the inner container 90.
Further, in some embodiments, two oppositely disposed laser range finders 20 form a set of laser detection units 30, and the detection device 10 includes multiple sets of laser detection units 30. That is, the plurality of sets of laser detection units 30 can simultaneously perform position adjustment and simultaneously detect the thickness of one wall 91 of the inner container 90 at different positions. This further improves the detection efficiency.
In addition, because laser range finder 20 can quick adjustment detect the position, consequently can carry out many times location and carry out repeated detection to a certain specific position in the short time, and then through setting up multiunit laser detecting element 30, detection device 10 can use different laser detecting element 30 to carry out repeated detection to same position, avoids because the holistic measurement accuracy of precision problem influence of a certain set of laser detecting element 30, improves the accuracy and the stability of testing result when guaranteeing detection efficiency from this.
In some embodiments, referring to fig. 5, a first rail 710 is disposed on each of the adjustment bars 71, and the laser range finder 20 is movably disposed on the first rail 710 to move along the first rail 710 by the driving of the driving unit 80. In some embodiments, the support rod 72 is provided with a second rail 720, and the at least one adjustment rod 71 is movably provided on the second rail 720 to move along the second rail 720 under the driving action of the driving unit 80. Specifically, the driving unit 80 may be a motor. The dotted double arrows in fig. 5 indicate the moving direction of the laser range finder 20 on the first rail 710 and the moving direction of the adjustment lever 71 on the second rail 720, respectively.
That is, the first rail 710 and the second rail 720 may respectively limit the moving direction and the stroke of the laser range finder 20 and the adjustment lever 71, so that the movement of the laser range finder 20 is smooth. Further, since the adjusting rods 71 are movably disposed on the second rails 720 of the supporting rods 72, when the thicknesses of the liners 90 with different sizes need to be measured, the distance between the two adjusting rods 71 can be adjusted according to the size of the liner 90. Thereby, the applicability of the detection apparatus 10 is enhanced.
In some embodiments, the opening of the inner container 90 placed on the transfer unit 40 faces one of the laser range finders 20. Specifically, the opening of the inner container 90 may be placed downward, and the laser range finders 20 are respectively located above and below the inner container 90. Further, the transfer unit 40 is configured to allow the laser of the laser range finder 20 to pass through the transfer unit 40 to reach the inner container 90. In alternative embodiments, the opening of the inner container 90 may also be placed upwardly.
In some specific embodiments, the transfer unit 40 includes a plurality of rollers 41, and the plurality of rollers 41 are spaced apart to allow the laser light emitted from the laser range finder 20 to pass through the gaps between the plurality of rollers 41 to reach the inner container 90.
In some embodiments, the detection device 10 further includes a processing unit 52 and a display unit 60. Specifically, the processing unit 52 is configured to calculate a thickness value of the measured inner container 90 based on the detection result of the laser range finder 20. The display unit 60 is used for outputting the measured thickness value of the inner container 90.
Referring to fig. 6, the detecting device 10 may include a main control unit 50, and the processing unit 52 and the control unit 51 may be integrated in the main control unit 50. The display unit 60 and the main control unit 50 may be installed at upper and lower portions of an operation table so that a user of the inspection apparatus 10 controls the inspection apparatus 10 through the main control unit 50 and acquires the inspection result through the display unit 60. In some embodiments, the display unit 60 may be a display. The processing unit 52 and the control unit 51 may be processors with corresponding computing functions.
In some embodiments, the processing unit 52 is further configured to generate a thickness profile of the liner 90 based on a plurality of thickness values of the liner 90 being measured. The display unit 60 is also configured to output the model of the measured inner bag and the thickness distribution map of the measured inner bag. Therefore, the thickness of the inner container 90 to be measured can be further conveniently analyzed by the user.
