Description

Technical Field

There will inevitably be some defects in the welded seams, such as pores, slag inclusions, incomplete penetration, lack of fusion, cracks, pits, undercut, weld beads, etc. In order to avoid the influence of the defects in the welded seams on the final product, it is usually necessary to use detection equipment to detect the defects of the welded seams of the welded panels.

Specific implementation mode

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0031] This implementation mode provides a butt - welded plate weld detection device, which can automatically detect the welds on the butt - welded plate.

[0032] See Figure 1 and Figure 2 The weld detection device of this implementation mode includes a detection platform 1, a two - dimensional translation mechanism 2, a weld detection assembly 3, a support member array, a plate positioning assembly, and a control terminal 9.

[0033] The detection platform 1 is a platform with a solid frame, and 6 support feet capable of adjusting the height are arranged at the lower part of the detection platform 1.

[0034] The support member array is installed on the tabletop of the detection platform 1, and this support member array is used to support the butt - welded plate as the weld detection object (hereinafter, the "butt - welded plate as the weld detection object" is simply referred to as the "detection object butt - welded plate").

[0035] Specifically, the support member array is composed of a large number of support members 4 combined. In this implementation mode, the number of support members 4 is 36, and all these 36 support members 4 are arranged at intervals in the form of a 6×6 rectangular array. The so - called "arranged at intervals" means that there is a certain interval gap between each support member 4, and there are gap channels between each column of support members 4 and between each row of support members 4. This gap channel is called the array channel of the support member array.

[0036] Take one arrangement dimension of the support member array as the first arrangement dimension of the support member array, and take the other arrangement dimension of the support member array as the second arrangement dimension of the support member array. Moreover, the first arrangement dimension of the support member array is perpendicular to the second arrangement dimension of the support member array. It should be noted that the arrangement dimension mentioned here refers to the longitudinal or transverse arrangement dimension direction of the support members 4 in the support member array.

[0037] As mentioned before, the support member array is a rectangular array, so it has 4 straight edges, and these 4 straight edges are respectively called the first edge, the second edge, the third edge, and the fourth edge. Taking Figure 1 the orientation shown, the lower left edge of the support member array is the first edge of the support member array, the lower right edge of the support member array is the second edge of the support member array, the upper right edge of the support member array is the third edge of the support member array, and the upper left edge of the support member array is the fourth edge of the support member array. Among them, the first edge is opposite to the third edge, and the second edge is opposite to the fourth edge.

[0038] It should be noted that in other embodiments, the number of support members 4 in the support member array can be determined according to actual needs.

[0039] For a single support member 4, the support member 4 is composed of a support column and a support plate. The lower end of the support column is fixedly installed on the tabletop of the detection platform 1, and the support plate is fixedly installed at the upper end of the support column. That is to say, the support plate is fixedly installed on the tabletop of the detection platform 1 through the support column.

[0040] The upper surfaces of all the support members 4 in the support member array are in the same plane, and this plane is called the main support plane of the support member array. This main support plane is also the plane position where the welded blank of the detection object is placed.

[0041] The support member 4 has two forms. One form is called the brush-type support member 41, and the other form is called the electromagnet-type support member 42. The main difference between the brush-type support member 41 and the electromagnet-type support member 42 lies in the different support plates.

[0042] The support plate of the brush-type support member 41 is a brush-type support plate. Specifically, a large number of bristles are arranged on the upper surface of the support plate of the brush-type support member 41, and these bristles cover the entire upper surface of the support plate. The bristles arranged on the support plate can prevent the support plate from scratching the welded blank of the detection object.

[0043] The support plate of the electromagnet-type support member 42 is an electromagnet-type support plate. Specifically, an electromagnet is arranged on the support plate of the electromagnet-type support member 42, and this electromagnet is used to adsorb and fix the welded blank of the detection object.

[0044] The support member array is essentially composed of a large number of brush-like support members 41 and a small number of electromagnetic support members 42. The electromagnetic support members 42 are evenly and discretely distributed in the support member array.

[0045] The plate positioning assembly is installed at the four peripheries of the support member array, and its function is to position the butt-welded plate of the detection object on the support member array. The plate positioning assembly includes an abutting table 6, a manual one-dimensional displacement mechanism 7, and a push plate assembly 8.

[0046] The number of the abutting tables 6 included in the plate positioning assembly is 6. These 6 abutting tables 6 are all installed on the detection platform 1, and these 6 abutting tables 6 are all arranged at the edge of the previously mentioned support member array. Specifically, the 6 abutting tables 6 are divided into two groups of abutting table combinations. Each group of abutting table combinations includes 3 abutting tables 6. One group of abutting table combinations is called the first abutting table combination, and the other group of abutting table combinations is called the second abutting table combination. It should be noted that in other embodiments, the number of the abutting tables 6 can be set to several according to needs, and the number of the abutting tables 6 in the abutting table combination can also be determined according to the actual situation.

[0047] The first abutting table combination is arranged at the first edge of the support member array, and the second abutting table combination is arranged at the second edge of the support member array. The edges of the support member array where the two groups of abutting table combinations are located are two adjacent edges. Whether it is the first abutting table combination or the second abutting table combination, the abutting tables 6 therein are all arranged along the edge of the support member array.

[0048] Taking Figure 1 the orientation shown, the 3 abutting tables 6 at the lower left edge of the support member array are the first abutting table combination, and the 3 abutting tables 6 at the lower right edge of the support member array are the second abutting table combination.

[0049] See Figure 5, for a single abutting platform 6, the abutting platform 6 includes a base frame 61, a second cylinder 62, a lifting seat 63 and an abutting block 64. The second cylinder 62 is installed on the base frame 61, and the telescopic end of the second cylinder 62 faces upward. The lifting seat 63 is installed on the telescopic end of the second cylinder 62, and the abutting block 64 is installed on the lifting seat 63. Two guide sleeves 611 are provided on the base frame 61, and two guide posts 631 are provided at the lower part of the lifting seat 63. The two guide posts 631 respectively correspond to the two guide sleeves 611 on the base frame 61. The central axes of the guide posts 631 and the guide sleeves 611 are both perpendicular to the horizontal plane. The two guide posts 631 at the lower part of the lifting seat 63 are respectively inserted into the two guide sleeves 611 of the base frame 61 to achieve the guiding effect. When the second cylinder 62 performs a telescopic action, it can drive the lifting seat 63 to drive the abutting block 64 to move up and down relative to the base frame 61. During the movement, the two guide posts 631 of the lifting seat 63 cooperate with the two guide sleeves 611 of the base frame 61 to achieve the guiding effect. Since the central axes of the guide posts 631 and the guide sleeves 611 are both perpendicular to the horizontal plane, it is ensured that the lifting seat 63 drives the abutting block 64 to move up and down perpendicular to the horizontal plane.

[0050] Regarding the previously mentioned "the abutting block 64 is installed on the lifting seat 63", specifically, a chute is provided at the upper part of the lifting seat 63, and a slider is provided at the lower part of the abutting block 64. The slider at the lower part of the abutting block 64 is embedded and installed in the chute at the upper part of the lifting seat 63 to achieve chute fitting. That is to say, the abutting block 64 is installed on the lifting seat 63 through a chute guiding mechanism. The operator can manually move the position of the abutting block 64 along the chute on the lifting seat 63, so as to adjust the position of the abutting block 64 on the lifting seat 63.

[0051] A proximity sensor is provided on the abutting block 64, and through this proximity sensor, a signal of the approaching of the butt-welded plate of the detection object can be sensed and obtained.

[0052] Regarding the previously mentioned "the abutting platforms 6 are all installed on the detection platform 1", specifically, the base frame 61 in the abutting platform 6 is fixedly installed on the detection platform 1. When the second cylinder 62 in the abutting platform 6 is at the retracted limit position, the abutting block 64 is below the main support surface of the support member array, and when the second cylinder 62 in the abutting platform 6 is at the extended limit position, the abutting block 64 spans the position of the main support surface of the support member array.

[0053] The function of the abutting table 6 is to cooperate with the push plate assembly 8 to position the welded blank of the object to be detected on the support member array. Specifically, the second cylinder 62 in the abutting table 6 is in the retracted limit position under normal conditions. That is to say, under normal conditions, the abutting block 64 is below the main support surface of the support member array. When it is necessary to position the welded blank of the object to be detected on the support member array, the telescopic end of the second cylinder 62 is controlled to extend to the extended limit position, and then the abutting block 64 spans at the position of the main support surface of the support member array. At the same time, the push plate assembly 8 pushes the welded blank of the object to be detected towards the abutting table 6 until the abutting block 64 of the abutting table 6 blocks the welded blank of the object to be detected. The combined action of the two can position the welded blank of the object to be detected.

[0054] See Figure 1 and Figure 6 As described above, the number of the manual one-dimensional displacement mechanisms 7 included in the plate positioning assembly is 3. These 3 manual one-dimensional displacement mechanisms 7 correspond to the 3 abutting tables 6 in the second abutting table combination. The 3 abutting tables 6 in the second abutting table combination are respectively installed on the tabletop of the detection platform 1 through the 3 manual one-dimensional displacement mechanisms 7. Or rather, each abutting table 6 in the second abutting table combination is installed on the tabletop of the detection platform 1 through a manual one-dimensional displacement mechanism 7, so as to realize the adjustment of the position of the abutting table 6, and further adjust the positioning position of the welded blank of the object to be detected on the support member array.

[0055] The manual one-dimensional displacement mechanism 7 is a device of the prior art. It has a handwheel 71 and a moving platform 72. By rotating the handwheel 71 of the manual one-dimensional displacement mechanism 7, the moving platform 72 of the manual one-dimensional displacement mechanism 7 can move forward or backward in a straight line along a dimension direction. The dimension direction in which the moving platform 72 of the manual one-dimensional displacement mechanism 7 moves in a straight line is called the moving dimension direction of the manual one-dimensional displacement mechanism 7.

[0056] Regarding the previously mentioned "each abutting table 6 in the second abutting table combination is installed on the tabletop of the detection platform 1 through a manual one-dimensional displacement mechanism 7", specifically, the manual one-dimensional displacement mechanism 7 is fixedly installed on the tabletop of the detection platform 1, and the abutting table 6 (base frame 61) is installed on the moving platform 72 of the manual one-dimensional displacement mechanism 7. From a top view, the moving dimension direction of the manual one-dimensional displacement mechanism 7 should intersect with the support member array. Or rather, when the handwheel 71 of the manual one-dimensional displacement mechanism 7 is manually rotated, the moving platform 72 of the manual one-dimensional displacement mechanism 7 can drive the abutting table 6 to approach or move away from the support member array.

[0057] See Figure 1 、 Figure 2 and Figure 7, the number of the push plate assemblies 8 included in the plate positioning assembly is 10. These 10 push plate assemblies 8 are all installed on the detection platform 1, and these 10 push plate assemblies 8 are all arranged at the edge of the previously mentioned support member array. Specifically, the 10 push plate assemblies 8 are divided into two groups of push plate assembly combinations. Each group of push plate assembly combinations includes 5 push plate assemblies 8. One group of push plate assembly combinations is called the first push plate assembly combination, and the other group of push plate assembly combinations is called the second push plate assembly combination. It should be noted that in other embodiments, the number of the push plate assemblies 8 can be set to several according to needs, and the number of the push plate assemblies 8 in the push plate assembly combination can also be determined according to the actual situation.

[0058] The first push plate assembly combination is arranged at the third edge of the support member array, and the second push plate assembly combination is arranged at the fourth edge of the support member array. The edges of the support member array where the two groups of push plate assembly combinations are located are two adjacent edges. Whether it is the first push plate assembly combination or the second push plate assembly combination, the push plate assemblies 8 therein are all arranged along the edge of the support member array, and each push plate assembly 8 corresponds to an array channel in the support member array.

[0059] In Figure 1 the orientation shown, the 5 push plate assemblies 8 at the upper right edge of the support member array are the first push plate assembly combination, and the 5 push plate assemblies 8 at the upper left edge of the support member array are the second push plate assembly combination.

[0060] For a single push plate assembly 8, the push plate assembly 8 includes a guide plate 81, a third cylinder 82, and a push and block column 83.

[0061] The guide plate 81 is installed on the support member array and is installed at an array channel of the support member array. The third cylinder 82 is installed on the guide plate 81. Both the guide plate 81 and the third cylinder 82 are located below the main support surface of the support member array.

[0062] Specifically, chutes are provided at the edges of each support member 4 in the support member array. The edge of the guide plate 81 has a structure matching the "chutes at the edges of the support member 4". The two side edges of the guide plate 81 are embedded and installed in the chutes of the support members 4 on both sides of the array channel of the support member array. The guide plate 81 can then perform chute-guided movement along the array channel where it is located. If the chutes at the edges of the support member 4 and the edge of the guide plate 81 are regarded as a chute-guided mechanism, the installation form of the guide plate 81 on the support member array can be summarized as: the guide plate 81 is installed in the array channel of the support member array through the chute-guided mechanism. Based on the chute-guided mechanism, the guide plate 81 can perform chute-guided movement along the array channel where it is located. That is to say, the third air cylinder 82 installed on the guide plate 81 can move along the array channel where it is located. The operator can manually drive the third air cylinder 82 to move in the array channel to adjust the position of the third air cylinder 82. Since the sizes of the butt-welded plates of the inspection objects vary, by adjusting the position of the third air cylinder 82, the weld inspection device can be adapted to butt-welded plates of different sizes of inspection objects.

[0063] The third air cylinder 82 is horizontally installed on the guide plate 81. The telescopic end of the third air cylinder 82 faces away from the support member array. The third air cylinder 82 is a cylinder of the festo brand, and its model is ADVU-32-50-A-P-A. The third air cylinder 82 is a rotary telescopic air cylinder. In addition to being able to extend and retract, the telescopic end of the third air cylinder 82 can also rotate 90 degrees.

[0064] The push block 83 is installed on the telescopic end of the third air cylinder 82. The central axis of the push block 83 is perpendicular to the central axis of the third air cylinder 82. When the telescopic end of the third air cylinder 82 extends to the extended limit position, the push block 83 is in a horizontal position. The entire horizontal push block 83 is located below the main support surface of the support member array. When the telescopic end of the third air cylinder 82 retracts and leaves the extended limit position, the telescopic end of the third air cylinder 82 will rotate 90 degrees, thereby driving the push block 83 to stand upright. The upright push block 83 then spans across the position of the main support surface of the support member array.

[0065] In addition, in order to facilitate the arrangement of electrical lines, a drag chain 84 is configured for each push plate assembly 8. One end of the drag chain 84 is installed on the inspection platform 1, and the other end of the drag chain 84 is connected to the cylinder body of the third air cylinder 82. Through the drag chain 84, the electrical lines of the third air cylinder 82 can be arranged without hindering the movement of the guide plate 81 along the array channel.

[0066] The function of the push plate assembly 8 is to cooperate with the abutment table 6 to position the test object tailor-welded blank on the support member array. Specifically, the telescopic end of the third cylinder 82 in the push plate assembly 8 is in the extended limit position under normal conditions. That is to say, under normal conditions, the push block column 83 installed on the telescopic end of the third cylinder 82 is in a lying state, and the whole push block column 83 is located below the main support surface of the support member array. When it is necessary to position the test object tailor-welded blank on the support member array, the telescopic end of the third cylinder 82 is controlled to retract. When the telescopic end of the third cylinder 82 leaves the extended limit position, it immediately rotates 90 degrees, driving the push block column 83 to stand upright. The push block column 83 then lies across the position of the main support surface of the support member array. The telescopic end of the third cylinder 82 continues to retract, so that the push block column 83 abuts against the test object tailor-welded blank, thereby pushing the test object tailor-welded blank to move towards the other side edge of the support member array, and the abutment table 6 at the other side edge will block the test object tailor-welded blank. The combined action of the two can position the test object tailor-welded blank.

[0067] More specifically, all 5 push plate assemblies 8 in the first push plate assembly combination act together to push the test object tailor-welded blank on the support member array towards the first abutment table combination until all 3 abutment tables 6 in the first abutment table combination block the test object tailor-welded blank, thereby realizing the positioning of the test object tailor-welded blank in one dimension. At the same time, all 5 push plate assemblies 8 in the second push plate assembly combination act together to push the test object tailor-welded blank on the support member array towards the second abutment table combination until all 3 abutment tables 6 in the second abutment table combination block the test object tailor-welded blank, thereby realizing the positioning of the test object tailor-welded blank in another dimension. The test object tailor-welded blank is positioned in both dimensions, thus realizing the overall positioning of the test object tailor-welded blank on the support member array.

[0068] See Figure 1 、 Figure 3 and Figure 4 As shown in

[0069] The weld detector 33 uses an electromagnetic ultrasonic detection device of the prior art. The brand of this electromagnetic ultrasonic detection device is "innerspec" and the model code is "800A1361". Four rollers are provided at the lower part of this electromagnetic ultrasonic detection device. When detecting a weld, the rolling direction of the rollers must be consistent with the direction of the weld. That is to say, the weld detector 33 has a directionality for detecting the weld. Therefore, when the weld detector 33 detects the weld, it is necessary to control the rotation of the stepper motor 32 to adjust the detection direction of the weld detector 33 so that the detection direction of the weld detector 33 is consistent with the direction of the weld.

[0070] In other embodiments, weld detection components of other structural forms may also be used, as long as they have a detection end face for detecting the weld.

[0071] Those of ordinary skill in the art can understand that the two-dimensional translation mechanism 2 is a device of the prior art. The two-dimensional translation mechanism 2 has its own driving force, and the two-dimensional translation mechanism 2 has a translation seat 21 that can move two-dimensionally. Two motors for lateral movement and longitudinal movement are installed on the two-dimensional translation mechanism 2. By controlling the operation of the two motors, the translation seat 21 of the two-dimensional translation mechanism 2 can be controlled to move two-dimensionally on the horizontal plane.

[0072] See Figure 1 and Figure 2 , the two-dimensional translation mechanism 2 is installed on the bench of the detection platform 1. The translation seat 21 of the two-dimensional translation mechanism 2 is located above the tabletop of the detection platform 1. The weld detection component 3 is installed on the translation seat 21 of the two-dimensional translation mechanism 2 and is above the main support surface of the support member array. The detection end face of the weld detection component 3 faces the main support surface of the support member array below. The translation seat 21 of the two-dimensional translation mechanism 2 can drive the weld detection component 3 to perform a two-dimensional movement on the horizontal plane above the main support surface of the support member array. As long as the movement path of the translation seat 21 of the two-dimensional translation mechanism 2 is controlled, welds with any direction on the test object, the welded plate, can be detected.

[0073] More specifically, a lifting drive mechanism 22 with its own driving force is installed on the translation seat 21 of the two-dimensional translation mechanism 2. The weld detection component 3 is installed on the translation seat 21 of the two-dimensional translation mechanism 2 through the lifting drive mechanism 22, and the lifting drive mechanism 22 can drive the weld detection component 3 to rise or fall.

[0074] See Figure 3 , the lifting drive mechanism 22 includes a base plate 221, a first cylinder 222, and a moving plate 223.

[0075] The substrate 221 is mounted on the translation base 21 of the two-dimensional translation mechanism 2. The substrate 221 is in an upright state. A vertical slide rail 224 is fixedly arranged on the substrate 221. A vertical rail groove is fixedly arranged on the moving plate 223. The slide rail 224 on the substrate 221 is assembled with the rail groove on the moving plate 223. The cylinder block of the first cylinder 222 is fixedly installed at the upper end of the substrate 221. The telescopic end of the first cylinder 222 faces downward. The telescopic end of the first cylinder 222 is installed and connected to the upper end of the moving plate 223. The telescopic action of the first cylinder 222 can drive the moving plate 223 to reciprocate along the slide rail 224 on the substrate 221. Or rather, the moving plate 223 can move up and down relative to the substrate 221.

[0076] It should be noted that the specific installation structure form of the previously mentioned "the weld detection component 3 is installed on the translation base 21 of the two-dimensional translation mechanism 2 through the lifting drive mechanism 22" is as follows: The substrate 221 of the lifting drive mechanism 22 is installed on the translation base 21 of the two-dimensional translation mechanism 2. The weld detection component 3 is installed on the moving plate 223 of the lifting drive mechanism 22. The first cylinder 222 in the lifting drive mechanism 22 can drive the weld detection component 3 to move up or down relative to the translation base 21 of the two-dimensional translation mechanism 2.

[0077] It should be noted that the specific installation structure form of the previously mentioned "the weld detection component 3 is installed on the moving plate 223 of the lifting drive mechanism 22" is as follows: The detection bracket 31 of the weld detection component 3 is installed on the moving plate 223 of the lifting drive mechanism 22.

[0078] The control terminal 9 is used to overall control the operation of the weld detection device and receive the weld detection data. And it can analyze the received weld detection data to determine whether the welded plate of the detection object is a qualified product.

[0079] Specifically, all signal devices in the weld detection device are electrically connected to the control terminal 9. Such as the weld detector 33 in the weld detection component 3 and the proximity sensor in the abutting table 6. The control terminal 9 can receive the weld detection data sent by the weld detection component 3 and the proximity signal sent by the proximity sensor of the abutting table 6. All electrical action components in the weld detection device are electrically connected to the control terminal 9 and are controlled by the control terminal 9. Such as the two-dimensional translation mechanism 2 (including the translation base 21, the lifting drive mechanism 22, etc.), the stepping motor 32 in the weld detection component 3, the electromagnetic support 42, the third cylinder 82 in the push plate assembly 8, etc.

[0080] The control terminal 9 is provided with a program for overall controlling the operation of the weld detection device and receiving weld detection data, and this program is called the weld detection control program. Based on this weld detection control program, the control terminal 9 can control the weld detection device to complete the weld detection of the butt-welded plate of the detection object. Specifically, the weld detection control program in the control terminal 9 can set the weld detection path according to the pre-determined weld direction, and the control terminal 9 can control the weld detection component 3 on the two-dimensional translation mechanism 2 to detect the weld according to the weld detection path.

[0081] It should be noted that using the control terminal 9 to achieve overall control of the operation of the weld detection device and receiving weld detection data is common knowledge that can be fully understood by those of ordinary skill in the art, and those skilled in the art can undoubtedly achieve the electrical connection between the control terminal 9 and other electrical components.

[0082] This embodiment also provides a butt-welded plate weld detection flow system, and this weld detection flow system is based on the above-mentioned butt-welded plate weld detection device.

[0083] See Figure 8 , in addition to including the above-mentioned butt-welded plate weld detection device, the weld detection flow system further includes a robot arm 11 and three workbenches.

[0084] The three workbenches are respectively a loading table 12, a qualified product unloading table 13, and a waste product unloading table 14. The loading table 12 is used to place the butt-welded plate of the detection object waiting for detection, the qualified product unloading table 13 is used to place the butt-welded plate of the detection object determined to be qualified after detection, and the waste product unloading table 14 is used to place the butt-welded plate of the detection object determined to be waste after detection.

[0085] The robot arm 11, the loading table 12, the qualified product unloading table 13, and the waste product unloading table 14 are arranged around the detection platform 1 of the weld detection device, and the robot arm 11 is controlled by the control terminal 9 of the weld detection device. The control terminal 9 of the weld detection device is provided with a program for controlling the movement of the robot arm 11, and this program is integrated in the weld detection control program of the control terminal 9. The actions that the control terminal 9 of the weld detection device can control the robot arm 11 to perform include: extracting the butt-welded plate of the detection object on the loading table 12 and placing it on the support member array of the weld detection device. After the weld detection device completes the detection of the butt-welded plate of the detection object, if it is determined that the butt-welded plate of the detection object is a qualified product, then extracting the butt-welded plate of the detection object on the support member array of the weld detection device and placing it on the qualified product unloading table 13. If it is determined that the butt-welded plate of the detection object is a waste product, then extracting the butt-welded plate of the detection object on the support member array of the weld detection device and placing it on the waste product unloading table 14.

[0086] SeeFigure 8 , Figure 1 and Figure 2 , the process of detecting the tailor-welded blank of the object to be detected by using the seam detection flow system of this embodiment is as follows:

[0087] Control the robot arm 11 to extract the tailor-welded blank 10 on the loading table 12 and place it on the support member array of the seam detection device. Control the plate positioning components (abutment table 6 and push plate assembly 8) in the seam detection device to position the tailor-welded blank 10 on the support member array. At the same time, control the electromagnetic support member 42 to adsorb and fix the tailor-welded blank 10. After the positioning is completed, control the two-dimensional translation mechanism 2 to start operating. The translation base 21 of the two-dimensional translation mechanism 2 drives the seam detection component 3 to detect the weld on the tailor-welded blank 10 along the pre-set seam detection path. Before the detection starts, it is necessary to lower the seam detection component 3 to a position where the detection end face is closely attached to the tailor-welded blank 10. After the detection is completed, raise the seam detection component 3 to disengage from the tailor-welded blank 10. The detection data obtained from the seam detection is transmitted to the control terminal 9. The control terminal 9 judges whether the detection data is qualified according to the pre-set judgment conditions. If so, it is determined that the tailor-welded blank 10 is a qualified product. If not, it is determined that the tailor-welded blank 10 is a defective product. The robot arm 11 transfers the tailor-welded blank 10 determined to be a qualified product to the qualified product unloading table 13, and the robot arm 11 transfers the tailor-welded blank 10 determined to be a defective product to the defective product unloading table 14. It should be noted that the above processes are all controlled and implemented by the seam detection control program in the control terminal 9.

[0088] It should be noted that in other embodiments, the robot arm 11 is not necessary, and the position transfer of the tailor-welded blank 10 can also be carried out manually.

[0089] In the seam detection device of this embodiment, the support member array on the detection platform 1 is used to place the tailor-welded blank 10, the plate positioning component is used to position the tailor-welded blank 10 on the support member array, the two-dimensional translation mechanism 2 is used to drive the seam detection component 3 to perform horizontal two-dimensional movement on the support member array, the seam detection component 3 is used to detect the weld on the tailor-welded blank 10, and the control terminal 9 is used to program and control the operation of the seam detection device and receive the seam detection data.

[0090] In the weld detection flow system of this embodiment, the loading table 12 is used to place the welded panel of the detection object waiting for detection, the qualified product unloading table 13 is used to place the welded panel of the detection object determined to be qualified after detection, the waste product unloading table 14 is used to place the welded panel of the detection object determined to be a waste product after detection, and the robotic arm 11 is used to transfer the welded panel of the detection object 10 between the weld detection device, the loading table 12, the qualified product unloading table 13 and the waste product unloading table 14.

[0091] The weld detection device of this embodiment can automatically detect the welds on the welded panel of the detection object 10, without manual participation during the detection process, and the detection of welds is fast and efficient, thus greatly improving work efficiency.

[0092] On the basis of the weld detection device, the weld detection flow system of this embodiment is also provided with a robotic arm 11, a loading table 12, a qualified product unloading table 13 and a waste product unloading table 14. The robotic arm 11 can transfer the welded panel of the detection object 10 between the weld detection device, the loading table 12, the qualified product unloading table 13 and the waste product unloading table 14, transfer the welded panel of the detection object on the loading table 12 to the weld detection device for detection, transfer the welded panel of the detection object determined to be qualified to the qualified product unloading table 13, and transfer the welded panel of the detection object determined to be a waste product to the waste product unloading table 14. In this way, the full automation of the weld detection of the batch of welded panels of the detection object is realized, and the whole process does not require manual participation, and continuous operation can be achieved, so that the whole weld detection process is fast and efficient, can meet the needs of large-scale production, and realizes a relatively high industrial level.

The weld detection component 3 on the right side in Figure 1 represents the state when the translation seat 21 of the two-dimensional translation mechanism 2 drives the weld detection component 3 to move to the rightmost side, and the weld detection component 3 on the left side in
