Detailed Implementation

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

Figure 5 - Figure 7 yes Figure 2 Enlarged views of point A from different angles. Figure 8 This is a schematic diagram of the workflow of an automatic stove detection device provided in this embodiment of the present invention. The first direction x1 and the second direction y are two mutually perpendicular directions on a horizontal plane. In this embodiment of the present invention, the first direction x1 and the second direction y can be understood as the x-axis and y-axis in a Cartesian coordinate system on a horizontal plane.

[0047] like Figure 1 - Figure 7As shown, the automatic stove inspection equipment includes an industrial control computer (not shown) and at least one automatic inspection unit 100. The automatic inspection unit 100 includes a barcode scanner 10, which is installed above the barcode scanner station and is used to acquire images of the stove delivered to the barcode scanner station. The stove is assembled from multiple parts, each part having a graphic code attached to it, which carries product information for that part. The industrial control computer includes an image receiver (not shown), which is electrically connected to the barcode scanner 10. The industrial control computer is used to identify the graphic codes on each part in the images acquired by the barcode scanner 10 and extract the product information carried by each graphic code. The industrial control computer is also used to determine whether the number of identified graphic codes meets the graphic code quantity standard for the current assembly stage, and, based on the product information carried by each graphic code, to determine whether each part meets the part matching requirements for the current assembly stage.

[0048] For details, please refer to Figure 8 When a partially assembled cooktop is transported to the barcode scanning station, the barcode scanning device 10 detects the graphic codes on the cooktop and automatically captures images of the graphic codes attached to each component to obtain image information containing the graphic codes. This avoids the tedious process of manually scanning each barcode with a barcode scanner, improving overall scanning efficiency and preventing missed scans. After the industrial control computer receives the image information transmitted by the barcode scanning device 10 through the image receiving end, it extracts the product information carried by the graphic codes based on its internally pre-set graphic code recognition algorithm and program. Compared to manual barcode recognition, the industrial control computer is unaffected by fatigue or lack of concentration, maintaining a stable and efficient recognition speed, greatly improving information extraction efficiency. Furthermore, the industrial control computer also determines whether the number of recognized graphic codes meets the standard for the current assembly stage, thus preventing missed scans. Finally, based on the product information carried by each graphic code, it quickly analyzes whether each component meets the component matching requirements for the current assembly stage, replacing manual analysis.

[0049] Continue to refer to Figure 1 In an optional embodiment, the stove is supported in an auxiliary tooling plate 20. The auxiliary tooling plate 20 is provided with an airtight channel (not shown in the figure). The airtight channel includes an air inlet 21 and an air outlet. The air outlet (not shown in the figure) is connected to the gas passage of the stove.

[0050] The automatic detection unit 100 also includes an air tightness tester 30, which includes a test head 31, which is positioned above the barcode scanning station.

[0051] The industrial control computer also includes an airtightness test terminal (not shown in the figure), which is electrically connected to the airtightness tester 30;

[0052] The industrial control computer is also used to control the test head 31 to connect with the air inlet 21 of the auxiliary tooling plate 20 and control the air tightness tester 30 to perform air tightness testing when it is determined that the number of identified graphic codes meets the graphic code number standard of the current assembly stage and the product information carried by each graphic code meets the component matching requirements of the current assembly stage.

[0053] Specifically, after the industrial control computer verifies that the number of graphic codes identified meets the standards for the current assembly stage and that all components meet the matching requirements, the automatic detection unit 100 performs an airtightness test on the stove. During the airtightness test, the stove is placed inside the auxiliary fixture plate 20, with the stove's gas passage connected to the airtightness outlet on the auxiliary fixture plate 20. The industrial control computer controls the pressure test head 31 to connect with the air inlet 21 on the auxiliary fixture plate 20 via the airtightness test terminal. Next, the industrial control computer controls the airtightness tester 30 to start working, injecting gas at a certain pressure into the airtightness channel. The gas passage of the stove is tested for airtightness by detecting parameters such as changes in gas pressure. If the airtightness test result meets the standard airtightness requirements, it indicates that the stove is qualified in terms of component assembly and gas passage airtightness, and it continues to the subsequent production process.

[0054] Continue to refer to Figure 1 In an optional embodiment, the automatic detection unit 100 further includes a position measuring device 40 for measuring the position of the auxiliary tooling plate 20;

[0055] The industrial control computer also includes a position receiver (not shown in the figure), which is electrically connected to the position measuring device 40;

[0056] The industrial control computer is also used to receive the position of the auxiliary tooling plate 20 detected by the position measuring device 40, and to determine whether the position of the auxiliary tooling plate 20 conforms to the preset position range before the control test head 31 is connected to the air inlet 21 of the auxiliary tooling plate 20.

[0057] Specifically, during the stove assembly process, the auxiliary tooling plate 20 may shift position due to various factors, such as vibration of the conveyor mechanism 120 or uneven wear of the conveyor belt. Therefore, when the auxiliary tooling plate 20 reaches the current detection position, the measuring device 40 detects the actual position of the auxiliary tooling plate 20 and transmits it to the position receiving end of the industrial control computer. The industrial control computer compares the measured actual position of the auxiliary tooling plate 20 with the preset position range. If the position of the auxiliary tooling plate 20 is within the preset position range, the air tightness tester 30 is activated to perform an air tightness test. If the actual position of the auxiliary tooling plate 20 deviates too much from the preset position, the pressure test head 31 may not be able to connect tightly with the air inlet 21. In this case, the relative position between the pressure test head 31 and the air inlet 21 of the auxiliary tooling plate 20 is further adjusted by other methods.

[0058] refer to Figure 2 and Figure 5 In an optional embodiment, the position measuring device 40 includes a first ranging sensor 41 and a second ranging sensor 42;

[0059] The first ranging sensor 41 is disposed on one side of the barcode scanning station in the first direction x1, and the second ranging sensor 42 is disposed on one side of the barcode scanning station in the second direction y; wherein, the first direction x1 and the second direction y are two mutually perpendicular directions on the horizontal plane.

[0060] The first distance sensor 41 is used to measure the distance between the auxiliary tooling plate 20 on the barcode scanning station and the first distance sensor 41 in the first direction x1;

[0061] The second distance sensor 42 is used to measure the distance between the auxiliary tooling plate 20 on the barcode scanning station and the second distance sensor 42 in the second direction y.

[0062] Specifically, the position measuring device 40 includes a first ranging sensor 41 and a second ranging sensor 42. The first ranging sensor 41 and the second ranging sensor 42 are used to detect the actual position of the auxiliary tooling plate 20 in the first direction x1 and the second direction y, respectively. By measuring in two mutually perpendicular directions, the two-dimensional position information of the auxiliary tooling plate 20 on the horizontal plane can be obtained. The distance data of the first ranging sensor 41 in the first direction and the distance data of the second ranging sensor 42 in the second direction are transmitted to the industrial control computer in real time. The industrial control computer compares and analyzes the received two-dimensional position information of the auxiliary tooling plate 20 on the horizontal plane with the pre-set standard position range of the auxiliary tooling plate 20 in the barcode scanning station. If the auxiliary tooling plate 20 is within the standard position range, the subsequent operation process can continue, such as performing an airtightness test. If the actual position of the auxiliary tooling plate 20 deviates too much from the preset position, the relative position between the pressure test head 31 and the air inlet 21 of the auxiliary tooling plate 20 is adjusted in the first direction x1 and the second direction y, avoiding detection errors or mistakes caused by the tooling plate position deviation.

[0063] Continue to refer to Figure 1 - Figure 7 In an optional embodiment, the automatic detection unit 100 further includes a moving device 50, which is mechanically connected to the test head 31;

[0064] The industrial computer also includes a mobile control terminal (not shown in the figure), which is electrically connected to the mobile device 50;

[0065] The industrial control computer is also used to control the moving device 50 to drive the test head 31 to align with the air inlet 21 on the auxiliary tooling plate 20 in the vertical direction when the position of the auxiliary tooling plate 20 does not conform to the preset position range.

[0066] Specifically, when the position of the auxiliary tooling plate 20 does not conform to the preset position range, the industrial control computer determines the offset of the auxiliary tooling plate 20 based on the information fed back by the position measuring device 40. Then, based on the offset, the industrial control computer sends a drive command to the control movement device 50, thereby driving the test head 31 to move horizontally, so as to align it with the air inlet 21 on the auxiliary tooling plate 20 in the vertical direction.

[0067] Continue to refer to Figure 1 - Figure 7 In an optional embodiment, the moving device 50 includes a first drive cylinder 51, a second drive cylinder 52, a first track 53, a second track 54, and an inverted component 55; the industrial control computer is provided with two moving control terminals, which are electrically connected to the first drive cylinder 51 and the second drive cylinder 52 respectively.

[0068] The first track 53 is positioned above the first drive cylinder 51, and the second track 54 is positioned above the second drive cylinder 52;

[0069] The second drive cylinder 52 is mounted on the first track 53 and slidably connected to the first track 53. The telescopic rod of the first drive cylinder 51 is connected to the second drive cylinder 52 to drive the second drive cylinder 52 to slide on the first track 53.

[0070] The test head 31 is mounted on the second track 54 via the inverted part 55 and is slidably connected to the second track 54. The extension rod of the second drive cylinder 52 is connected to the inverted part 55 to drive the inverted part 55 to slide on the second track 54.

[0071] Specifically, the first drive cylinder 51, serving as the power source for the moving device 50 in the first direction x1, is located on the lower layer of the moving device. The second drive cylinder 52, serving as the power source for the moving device 50 in the second direction y, is located on the first track 53 and slidably connected to it. When the position measuring device 40 detects that the position of the auxiliary tooling plate 20 does not conform to the preset position range, the moving control terminal of the industrial control computer sends control commands (including displacement amounts in the first direction x1 and the second direction y) to the first drive cylinder 51 and the second drive cylinder 52 respectively. The coordinated operation of the first drive cylinder 51 and the second drive cylinder 52 realizes the position adjustment of the entire displacement device on the horizontal plane, thereby aligning it with the test head 31 and the air inlet 21 on the auxiliary tooling plate 20.

[0072] Continue to refer to Figure 1 - Figure 7In an optional embodiment, the automatic detection unit 100 further includes a label printer 60, which is disposed above the barcode scanning station with its paper output outlet facing the barcode scanning station.

[0073] The industrial computer also includes a label control terminal (not shown in the figure), which is electrically connected to the label printer 60;

[0074] The industrial control computer is also used to control the label printer 60 to print a component defect label when the number of identified graphic codes does not meet the graphic code quantity standard for the current assembly stage, and to place the component defect label inside the auxiliary tooling plate 20 carrying the stove; and / or,

[0075] The industrial control computer is also used to control the label printer 60 to print a component defect label when it is determined, based on the product information carried by each graphic code, that a component does not meet the component matching requirements of the current assembly stage, and to place the component defect label inside the auxiliary tooling plate 20 that carries the stove; and / or,

[0076] The industrial control computer is also used to control the label printer 60 to print abnormal part labels when the air tightness test results do not meet the standard air tightness requirements, and to place the abnormal part labels in the auxiliary tooling plate 20 that carries the stove.

[0077] For details, please refer to Figure 8 After laser ranging and barcode scanning are completed, the industrial control computer (ICC) judges the detection results according to the preset control logic. If the ICC analyzes the image collected by the barcode scanning device 10 and determines that the number of recognized graphic codes does not meet the standard for the current assembly stage, it means that there may be missing parts or missing graphic codes. At this time, the ICC sends a command to the label printer 60 through the label control terminal to start the printing program, prints a barcode scanning error warning label on a pre-set label paper, and places the part error label in the auxiliary tooling plate 20 supporting the stove. Information such as "Barcode Missing" or "Error" is displayed. In addition, when the airtightness test fails, the ICC sends a command to the label printer 60 through the label control terminal to start the printing program, prints an airtightness error warning label on a pre-set label paper, and places the part error label in the auxiliary tooling plate 20 supporting the stove. Information such as "Airtightness Failed" is displayed so that subsequent staff can quickly understand the problem.

[0078] Continue to refer to Figure 2 In an optional embodiment, the automatic detection unit 100 further includes a support frame 110 and a conveying mechanism 120;

[0079] The support frame 110 has an entrance / exit (not shown in the figure) on one side, and a barcode scanning station and a conveyor channel are provided inside; the conveyor channel connects the entrance / exit and the barcode scanning station.

[0080] The conveying mechanism 120 is fixed inside the support frame 110 and located below the conveying channel.

[0081] Specifically, the main body of the automatic stove detection equipment is located below the conveying mechanism 120, and the supporting structure of the main body of the automatic detection equipment has an opening and a conveying channel on the side near the conveying mechanism 120. The workpiece passes through the inlet and outlet and the conveying channel, and finally arrives at the barcode scanning station.

[0082] Continue to refer to Figure 1 - Figure 3 In an optional embodiment, the automatic detection device includes two automatic detection units 100 arranged along a third direction x2, which intersects the path of the stove entering and exiting the automatic detection unit 100.

[0083] Specifically, in the stove production line, a single automatic detection unit 100 is less efficient than multiple automatic detection units 100. Therefore, at least two automatic detection units 100 are set on one side of the stove conveyor belt. To ensure that multiple stoves do not interfere with each other when entering and exiting, the two automatic detection units 100 are arranged along a third direction x2, and the third direction x2 intersects with the path of the stoves entering and exiting the automatic detection unit 100.

[0084] For example, such as Figure 2 As shown, in one embodiment, the third direction x2 is consistent with the first direction x1, and the stove enters and exits the automatic detection unit 100 along the second direction y.

[0085] In an optional embodiment, the present invention also provides a stove production line, which includes the aforementioned automatic stove testing equipment. Exemplarily, the stove production line includes a conveyor belt and the aforementioned automatic stove testing equipment, the conveyor belt being used to transport stoves to the automatic stove testing equipment. Since the stove production line includes at least one automatic stove testing device, it also possesses the functions and beneficial effects of an automatic testing device.

[0086] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
