[0041] The following is for reference. Figures 1 to 6 The detection device of this application will be described in detail.

[0042] refer to Figures 1 to 3The detection device according to an embodiment of the present invention includes a frame 100, a feeding module 200, a first detection module 300, a second detection module 400, a first transfer module 500, a second transfer module 600, and a unloading module 700. The frame 100 is provided with a feeding area, a first detection area, a transfer area, a second detection area, and an unloading area. The feeding module 200 is located in the feeding area and is used to provide the workpiece to be detected. The first detection module 300 is located in the first detection area and is used to perform visual inspection on the lower end of the workpiece. The second detection module 400 is located in the second detection area and is used to perform visual inspection on the upper end of the workpiece. The first transfer module 500 includes a first driving structure 510 and an adsorption structure. The first driving structure 510 is connected to the adsorption structure 520. Under the drive of the first driving structure 510, the adsorption structure 520 can adsorb the upper surface of the workpiece in the feeding area and drive the workpiece to move sequentially to the first detection area and the transfer area. The second transfer module 600 includes a second driving structure 610 and a support fixture 620. The second driving structure 610 is connected to the support fixture 620. Under the drive of the second driving structure 610, the support fixture 620 can receive the workpiece adsorbed by the adsorption structure 520 in the transfer area and drive the workpiece to move sequentially to the second detection area and the unloading area. The unloading module 700 is located in the unloading area and is used to unload the workpiece on the support fixture 620.

[0043] When the detection device in this embodiment is working, under the drive of the first driving structure 510, the adsorption structure 520 moves to the first detection area to adsorb the upper end of the workpiece provided by the feeding module 200. Then, the adsorption structure 520 drives the workpiece to move to the first detection area so that the lower end of the workpiece can be visually inspected by the first detection module 300. After that, the adsorption structure 520 drives the workpiece to the transfer area and places the adsorbed workpiece on the support fixture 620. Under the drive of the second driving structure 610, the support fixture 620 drives the workpiece to the second detection area so that the upper end of the workpiece on the support fixture 620 can be visually inspected by the second detection module 400. Then, the support fixture 620 drives the workpiece to the unloading area so that the workpiece on the support fixture 620 can be unloaded by the unloading module 700.

[0044] It is understood that in the detection device of this application, the adsorption structure 520 can adsorb the upper end of the workpiece, and under the drive of the first driving structure 510, the adsorption structure 520 can move the adsorbed workpiece to the first detection area so that the first detection module 300 can perform visual inspection on the lower end of the workpiece. The support fixture 620 can support the workpiece, and under the drive of the second driving structure 610, the support fixture 620 can move the supported workpiece to the second detection area so that the second detection module 400 can perform visual inspection on the upper end of the workpiece. Thus, the detection device of this application can complete the inspection of the upper and lower ends of the workpiece without flipping the workpiece. The detection device of this application provides more comprehensive visual inspection of the workpiece.

[0045] In some embodiments of this utility model, reference is made to Figure 1 The detection device also includes a third detection module 800. The frame 100 is also provided with a third detection area. The third detection module 800 is located in the third detection area and is used to perform appearance inspection on the side of the workpiece. Under the drive of the second drive structure 610, the carrying fixture 620 can receive the workpiece adsorbed by the adsorption structure 520 in the transfer area and drive the workpiece to move sequentially to the second detection area, the third detection area and the unloading area.

[0046] Then, driven by the second drive structure 610, the support fixture 620 moves to the second inspection area so that the second inspection module 400 can perform appearance inspection on the upper end of the workpiece. Next, the support fixture 620 drives the workpiece to the third inspection area so that the third inspection module 800 can perform appearance inspection on the periphery of the workpiece. After that, the support fixture 620 drives the workpiece to the unloading area so that the unloading module 700 can unload the workpiece on the support fixture 620.

[0047] It is understandable that the setting of the third inspection area and the third inspection module 800 enables the third inspection module 800 to inspect the circumferential surface of the workpiece on the support fixture 620, thereby improving the comprehensiveness of the inspection device of this application for the appearance inspection of the workpiece.

[0048] In some embodiments of this utility model, reference is made to Figure 1 The detection device also includes a first calibration module 900. A first calibration area is provided on the frame 100. The first calibration module 900 is located in the first calibration area and is used to perform position correction on the workpiece adsorbed by the adsorption structure 520 in the horizontal direction. The first driving structure 510 can drive the adsorption structure 520 to pass through the feeding area, the first calibration area, the first detection area and the transfer area in sequence.

[0049] It should be noted that when the adsorption structure 520 adsorbs the workpiece supplied by the feeding module 200, there are deviations in the adsorption position of the adsorption structure 520 on each workpiece. These deviations will cause differences in the appearance inspection of each workpiece by the subsequent first detection module 300.

[0050] It is understandable that by setting the first correction module 900, when the first driving structure 510 drives the adsorption structure 520 to move to the first correction area, the first correction module 900 can perform position correction on the workpieces adsorbed by the adsorption structure 520 in the horizontal direction, so that the adsorption position of the adsorption structure 520 on each workpiece is the same, thereby reducing the difference in appearance inspection of each workpiece by the subsequent first detection module 300.

[0051] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The first correction module 900 includes a third drive structure 910, an elastic connection structure 920, and a plurality of correction elements 930. The plurality of correction elements 930 are circumferentially spaced around a vertical axis and together define a correction area for correcting the workpiece. The elastic connection structure 920 is connected to each correction element 930 and is used to provide elastic force to keep the correction elements 930 close to the correction area. The third drive structure 910 is connected to each correction element 930 and is used to drive each correction element 930 to overcome the elastic force of the elastic connection structure 920 and move away from the correction area synchronously.

[0052] Understandably, under the drive of the third drive structure 910, the various correction components 930 move away from each other in the correction area. At this time, under the drive of the first drive structure 510, the adsorption structure 520 can normally drive the adsorbed workpiece into the correction area. Then, the third drive structure 910 stops driving the correction components 930. Under the elastic force of the elastic connection structure 920, the various correction components 930 move closer to each other in the correction area to push the workpiece in the correction area, thereby completing the correction of the workpiece in the correction area.

[0053] In some embodiments of this utility model, the elastic connection structure 920 is an elastic ring, and the correction members 930 are all disposed in the inner ring of the elastic ring and abut against the inner ring wall of the elastic ring.

[0054] Understandably, the elastic ring has a simple structure, low cost, and can synchronously drive each correction component 930 to move closer to each other.

[0055] In another embodiment of the present invention, the elastic connection structure 920 may also include a plurality of springs, wherein any two adjacent correctors 930 are connected to each other by a spring, and the spring is used to provide elastic force to keep the two correctors 930 close to each other.

[0056] In some embodiments of this utility model, the first correction module 900 further includes a mounting bracket 940, and the correction element 930 is slidably disposed on the mounting bracket 940 in a direction away from the correction area. The third drive structure 910 includes a driver 911 and a movable element 912. Each correction element 930 is arranged around the movable element 912. A plurality of abutting protrusions 912a are formed on the circumferential surface of the movable element 912. The abutting protrusions 912a are arranged one-to-one with the correction elements 930 in terms of quantity. The driver 911 is connected to the movable element 912 and is used to drive the movable element 912 to rotate around the vertical axis so that each abutting protrusion 912a can push each correction element 930 away from the correction area.

[0057] It is understood that a clearance structure is formed between any two adjacent abutting protrusions 912a. Under the drive of the actuator 911, the movable member 912 can rotate, so that the abutting protrusions 912a can push the corrector 930 away from the correction area. When the actuator 911 drives the movable member 912 to rotate until the clearance structure is directly opposite the movable member 912, under the elastic force of the elastic connection structure 920, the corrector 930 moves toward the clearance structure so that the corrector 930 moves closer to the correction area. Furthermore, by driving the movable member 912 to rotate, the actuator 911 can make the corrector 930 move closer to or away from the correction area.

[0058] It should be noted that when the moving part 912 pushes the calibrating part 930 to move, friction will occur between the moving part 912 and the calibrating part 930. Over time, this will cause significant wear on the moving part 912 and the calibrating part 930.

[0059] For the reasons stated above, in a further embodiment of this utility model, reference is made to... Figure 5 The correction component 930 is provided with a roller 931 that can be rotatably arranged around a vertical axis, and the roller 931 abuts against the circumferential surface of the movable component 912.

[0060] It is understandable that by setting the roller 931, when the movable part 912 pushes the roller 931, the roller 931 can rotate synchronously with the movable part 912, and the friction generated between the movable part 912 and the roller 931 is rolling friction, thereby reducing the wear between the movable part 912 and the correction part 930.

[0061] In some embodiments of this utility model, reference is made to Figure 1 The detection device also includes a second calibration module 1000. A second calibration area is provided on the frame 100. The second calibration module 1000 is located in the second calibration area and is used to perform position calibration on the workpiece on the support fixture 620 in the horizontal direction. The second drive structure 610 can drive the support fixture 620 to pass through the transfer area, the second calibration area, the second detection area and the unloading area in sequence.

[0062] It should be noted that after the adsorption structure 520 places the adsorbed workpieces on the support fixture 620, the positions of the workpieces on the support fixture 620 are not the same. Under these circumstances, the second detection module 400 has a large error in detecting the workpieces on the support fixture 620.

[0063] It is understandable that by setting up the second correction module 1000, when the second drive structure 610 drives the support fixture 620 to move to the second correction area, the second correction module 1000 can correct the workpiece so that each workpiece can be supported in the same position of the support fixture 620, thereby reducing the difference in appearance inspection of each workpiece by the subsequent second detection module 400.

[0064] It should be noted that the specific structure of the second calibration module 1000 is the same as that of the first calibration module 900.

[0065] In some embodiments of this utility model, multiple first detection modules 300 are provided in the first detection area, and the multiple first detection modules 300 can respectively detect different types of appearance defects on the lower end of the workpiece; multiple second detection modules 400 are provided in the second detection area, and the multiple second detection modules 400 can respectively detect different types of appearance defects on the upper end of the workpiece.

[0066] For example, such as Figure 1 As shown, there are two first detection modules 300 in the first detection area, and two second detection modules 400 in the second detection area.

[0067] It is understandable that by setting up multiple first detection modules 300 and multiple second detection modules 400, each first detection module 300 can detect a type of appearance defect in the workpiece, and each second detection module 400 can detect a type of appearance defect in the workpiece. Thus, the operator can select the appropriate first detection module 300 and second detection module 400 to perform the work according to the type of defect to be detected in the workpiece.

[0068] Further reference Figure 1 The third detection module 800 is provided in multiple locations in the third detection area. Each third detection module 800 is used to detect one type of appearance defect in the workpiece.

[0069] In some embodiments of this utility model, the detection device further includes a feeding conveyor line 1100 and a defective product collection module 1200. The feeding module 700 can feed good workpieces from the carrying fixture 620 to the feeding conveyor line 1100 and can feed defective workpieces from the carrying fixture 620 to the defective product collection module 1200.

[0070] Understandably, the unloading module 700 is electrically connected to the first inspection module 300, the second inspection module 400, and the third inspection module 800, respectively. When the first inspection module 300, the second inspection module 400, and the third inspection module 800 all pass the inspection of the workpiece, the unloading module 700 unloads the workpiece from the carrying fixture 620 to the unloading conveyor line 1100, which then transports the workpiece to the subsequent process. When at least one of the first inspection module 300, the second inspection module 400, and the third inspection module 800 fails the inspection of the workpiece, the unloading module 700 unloads the workpiece from the carrying fixture 620 into the defective product collection module 1200.

[0071] In a further embodiment of this utility model, reference is made to... Figure 6 The defective product collection module 1200 includes a guide structure 1210, a frame 1220, a first storage box 1230, and a second storage box 1240. The frame 1220 is provided with a main guide groove 1221, a first guide branch groove 1222, and a second guide branch groove 1223. The two opposite ends of the first guide branch groove 1222 are respectively connected to the main guide groove 1221 and the first storage box 1230. The two opposite ends of the second guide branch groove 1223 are respectively connected to the main guide groove 1221 and the first storage box 1240. The material box 1240 is connected, and the guide structure 1210 includes a motor 1211 and a guide plate 1212. The guide plate 1212 is rotatably disposed on the groove wall of the main guide groove 1221. The output end of the motor 1211 is connected to the guide plate 1212 and is used to drive the guide plate 1212 to rotate, so that the guide plate 1212 separates the main guide groove 1221 and the first guide sub-groove 1222, or separates the main guide groove 1221 and the second guide sub-groove 1223.

[0072] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
