[0030] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0031] Please see Figure 1 and Figure 2 This application provides a welding inspection device 100 for inspecting the welding quality of a first workpiece 220 and a second workpiece 230 welded onto a product 210. The product 210 can be a casing or display module of an electronic device such as a mobile phone or tablet. For ease of understanding, this application uses the example of a mobile phone display module as the product 210, a camera bracket as the first workpiece 220, and a hook as the second workpiece 230. Obviously, this is not a limitation of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the welding inspection device 100 includes a base 10, a turntable mechanism 20, a feeding mechanism 30, a first inspection mechanism 40, a second inspection mechanism 50, a third inspection mechanism 60, a fourth inspection mechanism 70, and a unloading mechanism 80.

[0033] The turntable mechanism 20 includes a rotary drive 21, a turntable 22, and multiple positioning components 23. The rotary drive 21 is located on the base 10, and the turntable 22 is connected to the rotary drive 21 so as to rotate under the drive of the rotary drive 21. Multiple positioning components 23 are spaced apart on the turntable 22 along the circumference of the turntable 22, and each positioning component 23 is used to position a product 210.

[0034] The feeding mechanism 30 is located on the base 10 and is used to feed the product 210 to be tested onto the positioning component 23.

[0035] The first testing mechanism 40 is located on the base 10 and is used to perform incomplete soldering and burn-through testing on the product 210.

[0036] The second inspection mechanism 50 is located on the base 10 and is used to inspect the appearance and welding slag of the first workpiece 220.

[0037] The third inspection mechanism 60 is located on the base 10 and is used to inspect the weld point position of the second workpiece 230.

[0038] The fourth inspection mechanism 70 is located on the base 10 and is used to inspect the weld point position of the first workpiece 220.

[0039] The unloading mechanism 80 is located on the base 10. The loading mechanism 30, the first inspection mechanism 40, the second inspection mechanism 50, the third inspection mechanism 60, the fourth inspection mechanism 70 and the unloading mechanism 80 are arranged at intervals around the turntable 22. The unloading mechanism 80 is used to pick up the inspected product 210 from the positioning component 23 and unload it.

[0040] Specifically, during the welding quality inspection process of the welding inspection device 100 on the first workpiece 220 and the second workpiece 230 welded onto the product 210: the rotary drive 21 drives multiple positioning components 23 to rotate sequentially to positions corresponding to the loading mechanism 30 via the turntable 22; the loading mechanism 30 loads the product 210 to be inspected sequentially onto the multiple positioning components 23; when the turntable 22 moves the positioning components 23 carrying the product 210 to the position corresponding to the first inspection mechanism 40, the first inspection mechanism 40 performs incomplete weld and burn-through inspection on the product 210; when the turntable 22 moves the positioning components 23 carrying the product 210 to the position corresponding to the second inspection mechanism 50, the second... The inspection mechanism 50 performs appearance and weld slag inspection on the first workpiece 220. When the turntable 22 moves the positioning component 23 carrying the product 210 to be inspected to the position corresponding to the third inspection mechanism 60, the third inspection mechanism 60 performs weld point position inspection on the second workpiece 230. When the turntable 22 moves the positioning component 23 carrying the product 210 to be inspected to the position corresponding to the fourth inspection mechanism 70, the fourth inspection mechanism 70 performs weld point position inspection on the first workpiece 220. When the turntable 22 moves the positioning component 23 carrying the inspected product 210 to the position corresponding to the unloading mechanism 80, the unloading mechanism 80 picks up the inspected product 210 from the positioning component 23 and unloads it. Thus, the welding inspection device 100 of this embodiment realizes the function of fully closed-loop automatic inspection of different welding parts of the welded product 210, and can perform multiple inspections on the welded product 210 with a low false judgment rate, thereby improving the efficiency and accuracy of inspecting the welding quality of the product 210. In addition, by setting up the turntable mechanism 20 and arranging the feeding mechanism 30, the first inspection mechanism 40, the second inspection mechanism 50, the third inspection mechanism 60, the fourth inspection mechanism 70 and the unloading mechanism 80 around the turntable 22 at intervals, the compactness of the welding inspection device 100 structure is improved, which facilitates the miniaturization of the welding inspection device 100.

[0041] In this embodiment, the rotary drive component 21 can be a direct drive motor with an absolute accuracy of ±10 arc-sec. It has high driving accuracy and small axial and radial runout, thereby improving the accuracy of driving the rotation of multiple positioning components 23 and improving the accuracy of the welding inspection device 100 in inspecting the welding quality of product 210.

[0042] In this embodiment, the flatness accuracy requirement of the turntable 22 is within ±0.08mm, thereby ensuring the consistency of the height of the positioning component 23 in the vertical direction, and thus improving the accuracy of the welding inspection device 100 in inspecting the welding quality of the product 210.

[0043] Please refer to the following: Figure 4In this embodiment, each positioning component 23 includes a positioning seat 231, a first positioning element 232, a second positioning element 233, a pressing element 234, and a pressing elastic element 235.

[0044] A positioning seat 231 is disposed on the turntable 22. The positioning seat 231 is used to support the product 210 and has an adsorption hole 2311 for adsorbing and fixing the product 210. A first positioning member 232 is disposed on the positioning seat 231 and located on one side of the adsorption hole 2311. A second positioning member 233 is disposed on the positioning seat 231 and located on the other side of the adsorption hole 2311. The first positioning member 232 and the second positioning member 233 are respectively used to abut against adjacent sides of the product 210. A clamping member 234 is slidably disposed on the positioning seat 231. The sliding direction of the clamping member 234 intersects with the arrangement direction of the first positioning member 232 and the second positioning member 233. The clamping member 234 has a first clamping part 2341 and a second clamping part 2342. The first clamping part 2341 is directly opposite to the first positioning member 232, and the second clamping part 2342 is directly opposite to the second positioning member 233. The two ends of the clamping elastic member 235 are respectively connected to the clamping member 234 and the positioning seat 231. The clamping elastic member 235 can be a tension spring. The clamping elastic member 235 is used to drive the clamping member 234 to approach the first positioning member 232 and the second positioning member 233, so that the first clamping part 2341 and the second clamping part 2342 respectively press the product 210 against the first positioning member 232 and the second positioning member 233.

[0045] When the positioning component 23 positions the product 210, the feeding mechanism 30 places the product 210 onto the positioning seat 231. The clamping elastic element 235 drives the clamping element 234 to approach the first positioning element 232 and the second positioning element 233. The first clamping part 2341 and the second clamping part 2342 respectively clamp the product 210 onto the first positioning element 232 and the second positioning element 233, thereby improving the accuracy of positioning the product 210. After the first clamping part 2341 and the second clamping part 2342 cooperate with the first positioning element 232 and the second positioning element 233 to clamp and position the product 210, the adsorption hole 2311 adsorbs and fixes the product 210 by vacuum adsorption, thereby effectively preventing the vertical plane of the product 210 from exceeding the detection range due to warping, and thus improving the accuracy of the welding inspection device 100 in detecting the welding quality of the product 210.

[0046] In this embodiment, the turntable mechanism 20 also includes a plurality of clamping components 24, which are spaced apart on the base 10 and located below the turntable 22. The plurality of clamping components 24 correspond to the feeding mechanism 30 and the unloading mechanism 80, respectively.

[0047] Each clamping assembly 24 includes a fixed base 241, a toggle drive 242, an clamping member 243, and a corrector 244. The fixed base 241 is located on the base 10 and below the turntable 22. The toggle drive 242 is located on the fixed base 241 and can be a telescopic cylinder. The clamping member 243 is connected to the toggle drive 242 and is used to actuate the clamping member 234 under the drive of the toggle drive 242, so that the clamping member 234 moves away from the first positioning member 232 and the second positioning member 233. The corrector 244 is detachably located on the toggle drive 242 or the fixed base 241 and is used to pass through the positioning base 231 to correct the position of the multiple positioning assemblies 23.

[0048] By setting up the toggle drive 242 and the clamping member 243, when the turntable 22 moves the positioning component 23 to a position corresponding to the loading mechanism 30 or the unloading mechanism 80, the toggle drive 242 drives the clamping member 234 away from the first positioning member 232 and the second positioning member 233 through the clamping member 243. This facilitates the loading mechanism 30 in placing the product 210 between the first positioning member 232, the second positioning member 233, the first clamping part 2341, and the second clamping part 2342, and facilitates the unloading mechanism 80 in removing the inspected product 210 from the positioning component 23. By setting up the calibration member 244, when the welding inspection device 100 is used for the first time or is being maintained, the calibration member 244 can be passed through the positioning seat 231 to correct the position of the multiple positioning components 23, thereby reducing the probability of positional deviation when the rotary drive 21 drives the multiple positioning components 23 to move through the turntable 22.

[0049] In this embodiment, the calibration component 244 can be a calibration pin. The calibration component 244 is plugged into or screwed into the connecting bracket 245 installed on the toggle drive component 242 or the fixed base 241. The positioning base 231 has a calibration hole 2312. The calibration component 244 passes through the calibration hole 2312 to calibrate the position of the multiple positioning components 23.

[0050] In this embodiment, the turntable mechanism 20 also includes a barcode scanner 26, which is disposed in the housing of the rotary drive component 21 (not shown) and corresponds to the feeding mechanism 30. When the feeding mechanism 30 feeds the product 210 to the positioning component 23, and the positioning component 23 positions the product 210, the barcode scanner 26 scans the barcode (not shown) on the product 210 to identify the information of the product 210 and enter it into the system. When the barcode scanner 26 fails to identify the information of the product 210, the feeding mechanism 30 picks up the product 210 and throws it away. This facilitates the traceability of the detection information of the product 210.

[0051] In this embodiment, the turntable mechanism 20 further includes multiple backlight modules 25, each of which can be a backlight source. These backlight modules 25 are spaced apart on the base 10 and located below the turntable 22, respectively corresponding to the second inspection mechanism 50 and the fourth inspection mechanism 70. This improves the accuracy of the second inspection mechanism 50 and the fourth inspection mechanism 70 in inspecting the welding quality of the product 210.

[0052] Please refer to the following: Figure 5 In this embodiment, the feeding mechanism 30 includes a transfer component 31 and a feeding component 32. The transfer component 31 includes a transfer seat 311 and a plurality of abutment members 312. The transfer seat 311 is disposed on the base 10, and the plurality of abutment members 312 are spaced apart on the transfer seat 311. The plurality of abutment members 312 enclose a positioning space 3121 for positioning the product 210 to be inspected. The feeding component 32 includes a robotic arm 321 and a suction member 322. The robotic arm 321 is disposed on the base 10 and located on one side of the transfer seat 311. The suction member 322 is connected to the robotic arm 321 and is used to remove the product 210 to be inspected from the positioning space 3121 under the drive of the robotic arm 321, and to feed the product 210 to be inspected onto the positioning component 23.

[0053] When the feeding mechanism 30 feeds the product 210 to be inspected, the transfer mechanism (not shown) from the previous process moves the product 210 to the transfer seat 311. Multiple abutting parts 312 abut against the product 210 from all sides and position the product 210 to be inspected. The robotic arm 321 drives the suction part 322 to remove the product 210 to be inspected from the positioning space 3121 and feed the product 210 to the positioning component 23. In this way, the feeding mechanism 30 has a simple structure and improves the accuracy of feeding the product 210 to be inspected.

[0054] Please refer to the following: Figure 6 In this embodiment, the first detection mechanism 40 includes a cold solder joint detection component 41 and a solder burn-through detection component 42. The cold solder joint detection component 41 includes a moving drive component 411 and a cold solder joint detection component 412. The moving drive component 411 is disposed on the base 10, and the cold solder joint detection component 412 is connected to the moving drive component 411. The cold solder joint detection component 412 is used to perform cold solder joint detection on the product 210. The solder burn-through detection component 42 includes a moving drive component 421 and a solder burn-through detection component 422. The moving drive component 421 is disposed on the base 10 and located on one side of the moving drive component 411. The solder burn-through detection component 422 is connected to the moving drive component 421, and the solder burn-through detection component 422 is used to perform solder burn-through detection on the product 210.

[0055] When the first detection structure inspects product 210, the moving drive component 411 drives the cold solder joint detection component 412 to move above product 210, whereby the cold solder joint detection component 412 performs cold solder joint detection on product 210. Meanwhile, the moving drive component 421 drives the burn-through detection component 422 to move below product 210, whereby the burn-through detection component 422 performs burn-through detection on product 210. Thus, the first detection mechanism 40 has a simple structure and improves the accuracy of cold solder joint and burn-through detection on product 210.

[0056] In this embodiment, the moving drive component 411 is a linear motor with a repeatability of ±1µm and a dynamic compensation range of ±5µm. A grating ruler position feedback is used to improve accuracy. The moving drive component 411, in conjunction with the turntable 22, effectively eliminates the impact of equipment vibration and repositioning errors on the inspection, thereby improving the accuracy of the weld defect detection component 412 in detecting weld defects in product 210. The weld defect detection component 412 is a 3D camera with a vertical resolution of 0.0004mm / 0.0002mm and a field of view of 36mm, which can cover the inspection requirements of the first workpiece 220 and the second workpiece 230, further improving the accuracy of the weld defect detection component 412 in detecting weld defects in product 210.

[0057] In this embodiment, the motion drive 421 is a linear motor with a repeatability of ±1µm and a dynamic compensation range of ±5µm. A grating ruler position feedback is used to improve accuracy, thereby enhancing the accuracy of driving the weld penetration detection component 422. The weld penetration detection component 422 is a global camera that inspects for excessive solder joint energy through the glass (not shown) below the product 210, thereby determining whether there are any abnormal burn points (such as red dots within the detection area), thus improving the accuracy of the weld penetration detection component 422 in detecting weld penetration on the product 210.

[0058] Please refer to the following: Figure 7 In this embodiment, the second detection mechanism 50 includes a linear drive 51 and an imaging element 52. The linear drive 51 is disposed on the base 10, and the imaging element 52 is connected to the linear drive 51. The imaging element 52 is used to perform appearance and welding slag inspection on the first workpiece 220. Thus, the structure of the second detection mechanism 50 is simple and the accuracy of appearance and welding slag inspection on the first workpiece 220 is improved.

[0059] In this embodiment, the imaging component 52 is a 2D camera, the linear drive component 51 is a linear motor, the repeatability positioning accuracy is ±1µm, the dynamic compensation range is ±5µm, and the position feedback of the grating ruler is used to improve the accuracy, thereby improving the accuracy of driving the imaging component 52 to move, and further improving the accuracy of the imaging component 52 in inspecting the appearance and welding slag of the first workpiece 220.

[0060] Please refer to the following: Figure 8 In this embodiment, the third detection mechanism 60 includes a transverse linear module 61, a longitudinal linear module 62, and an identification element 63. The transverse linear module 61 is disposed on the base 10. The longitudinal linear module 62 is connected to the transverse linear module 61. The identification element 63 is connected to the longitudinal linear module 62, and the identification element 63 is used to detect the weld point position of the second workpiece 230. The identification element 63 can be a 2D camera.

[0061] Since there are a large number of second workpieces 230, by setting up a horizontal linear module 61 and a vertical linear module 62 to drive the identification component 63 to move, the detection area covered by the identification component 63 is larger, thereby improving the accuracy of the third detection mechanism 60 in detecting the weld point position of the second workpiece 230.

The weld point detection component 73 is connected to the linear drive component 72. The weld point detection component 73 can be a 2D camera and is used to detect the weld point position of the second workpiece 230. Thus, the fourth detection mechanism 70 has a simple structure and improves the accuracy of weld point position detection on the second workpiece 230.

[0063] Please refer to the following: Figure 10 In this embodiment, the unloading mechanism 80 includes a transfer drive 81, an unloading fixture 82, and a gripping assembly 83. The transfer drive 81 is mounted on the base 10 and can be a linear motor. The unloading fixture 82 is connected to the transfer drive 81 and moves under its drive. The gripping assembly 83 is located on one side of the transfer drive 81 and is used to grip the inspected product 210 from the positioning assembly 23 and place it onto the unloading fixture 82. The transfer drive 81 drives the unloading fixture 82 and the inspected product 210 to move to the position corresponding to the next workstation. Thus, the unloading mechanism 80 has a simple structure and improves the efficiency and accuracy of unloading the product 210.

[0064] Please refer to the following: Figure 11 In this embodiment, the feeding fixture 82 includes a support seat 821, a first limiting member 8221, a second limiting member 8222, a first pressing member 8231, a second pressing member 8232, a first elastic member 8241, a second elastic member 8242, a first driving member 8251, and a second driving member 8252.

[0065] The support base 821 is connected to the transfer drive component 81. A first limiting component 8221 is disposed on the support base 821. A second limiting component 8222 is disposed on the support base 821 and located to one side of the first limiting component 8221. A first pressing component 8231 is slidably disposed on the support base 821 and is directly opposite to the first limiting component 8221. The two ends of a first elastic component 8241 are respectively connected to the first pressing component 8231 and the support base 821. The first elastic component 8241 is used to drive the first pressing component 8231 closer to the first limiting component 8221, so that the first pressing component 8231 presses the inspected product 210 against the first limiting component 8221. A first drive component 8251 is disposed on the support base 821 and abuts against the first pressing component 8231. The first drive component 8251 is used to drive the first pressing component 8231 away from the first limiting component 8221.

The two ends of the second elastic member 8242 are connected to the second extruder 8232 and the support seat 821, respectively. The second elastic member 8242 is used to drive the second extruder 8232 closer to the second limiting member 8222, so that the second extruder 8232 presses the tested product 210 against the second limiting member 8222.

The second driving member 8252 is used to drive the second extruder 8232 away from the second limiting member 8222.

[0066] When the gripping component 83 moves the inspected product 210 onto the unloading fixture 82, the first driving component 8251 drives the first extrusion component 8231 away from the first limiting component 8221, and the second driving component 8252 drives the second extrusion component 8232 away from the second limiting component 8222, thereby facilitating the gripping component 83 to move the inspected product 210 between the first limiting component 8221, the second limiting component 8222, the first extrusion component 8231, and the second extrusion component 8232. Subsequently, the first driving member 8251 disengages from the first pressing member 8231, and the second driving member 8252 disengages from the second pressing member 8232. The first elastic member 8241 drives the first pressing member 8231 to approach the first limiting member 8221, and the second elastic member 8242 drives the second pressing member 8232 to approach the second limiting member 8222. The first pressing member 8231 and the second pressing member 8232 respectively press the inspected product 210 against the first limiting member 8221 and the second limiting member 8222, thereby improving the accuracy of positioning the inspected product 210 in the unloading fixture 82 and facilitating the accurate removal of the inspected product 210 from the unloading fixture 82 by the pick-and-place mechanism (not shown) of the next workstation.

[0067] In this embodiment, the unloading fixture 82 also includes a suction cup 826. The suction cup 826 is disposed on the support seat 821 and located between the first limiting member 8221, the second limiting member 8222, the first pressing member 8231 and the second pressing member 8232. The suction cup 826 is used to adsorb and fix the product 210, thereby improving the stability of the product 210 after the unloading fixture 82 has been positioned and detected.

[0068] In this embodiment, the gripping assembly 83 includes a support frame 831, a horizontal linear module 832, a vertical drive component 833, and a pick-and-place component 834. The support frame 831 is located on one side of the transfer drive component 81. The horizontal linear module 832 is located on the support frame 831 and above the transfer drive component 81. The driving direction of the horizontal linear module 832 is perpendicular to the driving direction of the transfer drive component 81. The vertical drive component 833 is connected to the horizontal linear module 832 and can be a telescopic cylinder. The pick-and-place component 834 is connected to the vertical drive component 833 to move vertically under the drive of the vertical drive component 833. The pick-and-place component 834 can be a vacuum nozzle. Thus, the gripping assembly 83 has a simple structure and improves the accuracy of picking and placing the product 210 after inspection.
