[0063] Compared with the content of the background technology introduction, in the actual application process of the above detection device, by placing the middle frame U-shaped part to be detected at the loading position of the loading module, the loading module can convey the middle frame U-shaped part to be detected to the picking position. The picking mechanism of the transfer module grabs the middle frame U-shaped part at the picking position, and then drives the picking mechanism to move to the transfer station through the transfer mechanism. Then, the middle frame U-shaped part grabbed by the picking mechanism is released onto the positioning module, and the positioning module positions the middle frame U-shaped part to facilitate subsequent handling. The handling module grabs the middle frame U-shaped part on the positioning module and transports the grabbed middle frame U-shaped part to the first detection station. When it is transported to the first detection station, the first detection module arranged in the detection component detects the opening size of the middle frame U-shaped part grabbed on the handling module that reaches the first detection station. After the opening size detection is completed, the middle frame U-shaped part is transported to the detection pipeline by the handling module. There is a positioning fixture on the detection pipeline for receiving the middle frame U-shaped part transported by the handling module. The detection pipeline transports the middle frame U-shaped part carried by the positioning fixture to the second detection station. When it is transported to the second detection station, the second detection module performs code scanning and first shape defect detection on the middle frame U-shaped part located at the second detection station. After the code scanning and first shape defect detection are completed, the detection pipeline transports the middle frame U-shaped part carried by the positioning fixture to the third detection station, and the third detection module performs second shape defect detection on the middle frame U-shaped part located at the third detection station. After the second shape defect detection is completed, the detection pipeline transports the middle frame U-shaped part carried by the positioning fixture to the sorting station. Since the blanking bin assembly at the blanking station includes a qualified blanking area and an unqualified blanking area, the sorting module grabs and sorts the middle frame U-shaped parts at the sorting station, sorts the qualified middle frame U-shaped parts to the qualified blanking area, and sorts the unqualified middle frame U-shaped parts to the unqualified blanking area, thus completing the opening size detection, first shape defect detection, and second shape defect detection of the middle frame U-shaped parts. Since in the entire detection process using the above detection device, only the middle frame U-shaped part to be detected needs to be placed at the loading position of the loading module, the detection device can automatically perform handling and complete the opening size detection, first shape defect detection, and second shape defect detection, greatly saving the cumbersome manual operation process, greatly improving the detection efficiency, greatly reducing the labor intensity, and avoiding the problem of inaccurate and unstable detection results caused by the influence of human factors.

[0086] The core of the present invention is to provide a detection device of the present invention to solve the problems of low detection efficiency, poor accuracy and stability of the detection results of the middle frame U-shaped parts.

[0087] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0088] Refer to Figures 1 - 12As shown in the figure, the utility model provides a detection device for detecting the middle frame U-shaped part 8 of a mobile phone, which includes a feeding module 1, a transfer module 2, a positioning module 3, a handling module 4, a detection component 5, a blanking bin component 6 and a sorting module 7. Among them, the feeding module 1 is arranged at the feeding station 10 and is used to carry the middle frame U-shaped part 8 to be detected, and has a feeding position 11 and a picking position 12. The feeding position 11 is used to place the middle frame U-shaped part 8 to be detected. Its feeding method can be but is not limited to manual placement. For example, it can also adopt the method of automatically placing by designing a manipulator, and no specific limitation is made here. In addition, the feeding module 1 can convey the middle frame U-shaped part 8 to be detected at the feeding position 11 to the picking position 12. The conveying process can be active driving conveying, such as active conveying by a conveyor belt, etc., or passive conveying. For example, the feeding module 1 is designed as an inclined chute structure and freely slides from the feeding position 11 to the picking position 12 under the action of gravity. In the actual application process, it can be arranged according to actual needs, and no more specific limitation is made here; The transfer module 2 includes a transfer mechanism 21 and a picking mechanism 22 arranged on the transfer mechanism 21. The picking mechanism 22 is used to grab the middle frame U-shaped part 8 at the picking position 12, and the transfer mechanism 21 is used to drive the picking mechanism 22 to move to the transfer station 30, where the picking mechanism 22 can release the middle frame U-shaped part 8 according to the corresponding position it is transported to; The positioning module 3 is arranged at the transfer station 30 and is used to receive the middle frame U-shaped part 8 grabbed by the picking mechanism 22 and position it. The purpose of this positioning is to facilitate better handling in the subsequent process; The handling module 4 is used to grab the middle frame U-shaped part 8 of the positioning module 3 and sequentially transport the grabbed middle frame U-shaped part 8 to the first detection station 501 and the detection pipeline 502. A positioning fixture 503 for receiving the middle frame U-shaped part 8 transported by the handling module 4 is arranged on the detection pipeline 502, and the detection pipeline 502 is used to sequentially transport the middle frame U-shaped part 8 carried by the positioning fixture 503 to the second detection station 504, the third detection station 505 and the sorting station; The detection component 5 includes a first detection module 51, a second detection module 52 and a third detection module 53; Among them, the first detection module 51 is arranged at the first detection station 501 and is used to detect the opening size of the middle frame U-shaped part 8 grabbed on the handling module 4 when it reaches the first detection station 501; The second detection module 52 is arranged at the second detection station 504 and is used to perform code scanning and first shape defect detection on the middle frame U-shaped part 8 located at the second detection station 504; The third detection module 53 is arranged at the third detection station 505 and is used to perform second shape defect detection on the middle frame U-shaped part 8 located at the third detection station 505; The blanking bin component 6 is arranged at the blanking station 60 and includes a qualified blanking area and an unqualified blanking area; The sorting module 7 is used to grab and sort the middle frame U-shaped part 8 at the sorting station, and sort the qualified middle frame U-shaped parts 8 to the qualified blanking area and the unqualified middle frame U-shaped parts 8 to the unqualified blanking area.

[0089] In the actual application process of the above detection device, the middle frame U-shaped part 8 to be detected is placed at the loading position 11 of the loading module 1. The loading module 1 can convey the middle frame U-shaped part 8 to be detected to the picking position 12. The picking mechanism 22 of the transfer module 2 grabs the middle frame U-shaped part 8 at the picking position 12, and then the transfer mechanism 21 drives the picking mechanism 22 to move to the transfer station 30. Then, the middle frame U-shaped part 8 grabbed by the picking mechanism 22 is released onto the positioning module 3, and the positioning module 3 positions the middle frame U-shaped part 8 to facilitate subsequent handling. The handling module 4 grabs the middle frame U-shaped part 8 of the positioning module 3 and transports the grabbed middle frame U-shaped part 8 to the first detection station 501. When it is transported to the first detection station 501, the first detection module 51 provided in the detection component 5 detects the opening size of the middle frame U-shaped part 8 grabbed on the handling module 4 that reaches the first detection station 501. After the opening size detection is completed, the middle frame U-shaped part 8 is transported to the detection pipeline 502 by the handling module 4. A positioning fixture 503 for receiving the middle frame U-shaped part 8 transported by the handling module 4 is provided on the detection pipeline 502. The detection pipeline 502 transports the middle frame U-shaped part 8 carried by the positioning fixture 503 to the second detection station 504. When it is transported to the second detection station 504, the second detection module 52 performs code scanning and first shape defect detection on the middle frame U-shaped part 8 located at the second detection station 504. After the code scanning and first shape defect detection are completed, the detection pipeline 502 transports the middle frame U-shaped part 8 carried by the positioning fixture 503 to the third detection station 505, and the third detection module 53 performs second shape defect detection on the middle frame U-shaped part 8 located at the third detection station 505. After the second shape defect detection is completed, the detection pipeline transports the middle frame U-shaped part 8 carried by the positioning fixture 503 to the sorting station. Since the blanking bin assembly 6 provided at the blanking station 60 includes a qualified blanking area and an unqualified blanking area, the sorting module 7 grabs and sorts the middle frame U-shaped part 8 at the sorting station, and the qualified middle frame U-shaped parts 8 can be sorted into the qualified blanking area, and the unqualified middle frame U-shaped parts 8 can be sorted into the unqualified blanking area, thereby completing the opening size detection, first shape defect detection, and second shape defect detection of the middle frame U-shaped part 8.

[0090] It should be noted that the above middle frame U-shaped part 8 can always be carried on the positioning fixture 503 during code scanning, first shape defect detection, and second shape defect detection, and the positioning of the positioning fixture 503 for the middle frame U-shaped part 8 does not affect its code scanning, first shape defect detection, and second shape defect detection.

[0091] During the entire detection process using the above detection device, it is only necessary to place the middle frame U-shaped part to be detected at the loading position of the loading module. The detection device can automatically perform handling and complete the opening size detection, the first shape defect detection, and the second shape defect detection, greatly saving the cumbersome manual operation process, greatly improving the detection efficiency, greatly reducing the labor intensity, and avoiding the problem that the detection result is inaccurate and unstable due to the influence of human factors.

[0092] In some specific embodiments, referring to Figure 2 As shown, the above loading module 1 may specifically include a loading bracket 13 and a loading chute 14: Among them, the loading bracket 13 is arranged at the loading station 10, and it may specifically but not limitedly be designed as a bracket structure formed by multiple columns; the loading chute 14 is arranged on the loading bracket 13 in a top-down inclined manner. Among them, the loading position 11 is arranged at the inclined upper end of the loading chute 14, and the picking position 12 is arranged at the inclined lower end of the loading chute 14, so that the middle frame U-shaped part 8 placed on the loading chute 14 from the loading position 11 can automatically slide down to the picking position 12; and specifically, the loading chute 14 may include parallel slide rails 141 that are slidably adapted to the opening of the middle frame U-shaped part 8 and a limiting bracket 142 that is arranged above the parallel slide rails 141 and is used for slidably adapting to the opposite side of the opening of the middle frame U-shaped part 8, and the limiting bracket 142 forms an avoidance for the loading position 11 and the picking position 12. The specific structure of the limiting bracket 142 may specifically but not limitedly adopt a suspended limiting member arranged along the extension direction of the parallel slide rails, and it may be specifically fixed by fixed rib plates arranged at intervals in sequence. By designing the loading module 1 into the above structural form, the loading module 1 can make the middle frame U-shaped part 8 automatically convey from the loading position 11 to the picking position 12 without additional configuration of a conveying mechanism, and under the limiting action of the limiting bracket 142, multiple middle frame U-shaped parts 8 can be stacked in a closely adjacent manner on the parallel slide rails 141. When one middle frame U-shaped part 8 is taken away at the picking position 12, one middle frame U-shaped part 8 automatically slides down to the picking position 12, and the action connection is coherent, which helps to improve the work efficiency. Of course, it can be understood that the above is only a preferred example of the structure of the loading module 1 of the present utility model. In the actual application process, it can also be designed into other structural forms, such as the active conveying mode of a conveyor belt, etc., and no more specific limitation is made here.

[0093] In some other specific embodiments, referring to Figure 2As shown, the above-mentioned material picking mechanism 22 can specifically include a material picking bracket 221, a flipping drive 222, a telescopic mechanism 223 and a gripping portion 224. The transfer mechanism 21 can be specifically constructed as a linear drive mechanism. The material picking bracket 221 is arranged on the linear drive mechanism. The linear drive mechanism is used to drive the material picking bracket 221 to move from the loading station 10 to the transfer station 30. The starting end of the telescopic mechanism 223 is rotatably arranged on the material picking bracket 221 through a flipping shaft 225. The flipping drive 222 is used to drive the telescopic mechanism 223 to rotate around the flipping shaft 225. The flipping shaft 225 is horizontally arranged and perpendicular to the linear driving direction of the linear drive mechanism. The gripping portion 224 is arranged at the end of the telescopic mechanism 223 and is used to grip the middle frame U-shaped part 8. In actual application, the material picking bracket 221 can be transported to the loading station 10 by the linear drive mechanism. At this time, the flip driver 222 is flipped and the telescopic mechanism 223 is controlled to be telescopic, so that the grabbing part 224 can move to the material picking position 12 and grab the middle frame U-shaped part 8 of the material picking position 12. Then, after the telescopic mechanism 223 is controlled to retract, the linear drive mechanism drives the material picking bracket 221 to move to the transfer station 30. Then, by controlling the combined movement of the flip driver 222 and the telescopic mechanism 223, the middle frame U-shaped part 8 can be placed on the positioning module 3 of the transfer station 30. The operation is very coherent.

[0094] Among them, the material-grabbing mechanism 22 is similar to a manipulator, the telescopic mechanism 223 can be driven by a cylinder but is not limited to it, the grabbing and releasing actions of the grabbing part 224 can also be driven by a cylinder but is not limited to it, and the specific structure of the linear drive mechanism can be driven by a screw mechanism in conjunction with a servo motor but is not limited to it. It should be noted that in order to accurately obtain the current position of the grabbing part 224 and whether the corresponding grabbing action is completed, the corresponding grabbing part 224 is generally designed with a corresponding sensor with a corresponding function, such as a photoelectric sensor to detect the position and whether the middle frame U-shaped part 8 is grabbed.

[0095] It should be noted that, refer to Figure 2 and 3 , combined with Figure 1 As shown in , the above-mentioned loading module 1 and transfer module 2 can be specifically designed as two groups arranged in a connected manner. Of course, the corresponding positioning module 3 can also be designed in two groups. Such a matching design can help improve work efficiency.

[0096] In some other specific implementation schemes, refer to Figure 3As shown in the figure, the above-mentioned positioning module 3 may specifically include a positioning bracket 31, a bearing part 32, a first clamping and positioning mechanism 33, and a second clamping and positioning mechanism 34.

The handling module 4 of the above-mentioned structural form can drive the first gripper to perform three-dimensional movement, and the structure is relatively simple and easy to implement. It should be noted that the driving method of the X-axis, Y-axis and Z-axis of the above-mentioned first three-axis motion mechanism 42 can be, but is not limited to, a combination of one or more driving methods such as a lead screw and a servo motor drive, a cylinder drive, etc. In actual application, it can be selected according to actual needs, and no more specific restrictions are made here. In addition, in order to facilitate the acquisition of the current position of the first gripper and whether the middle frame U-shaped part 8 is grasped, the corresponding first gripper is generally provided with a sensor with corresponding function, such as a photoelectric sensor.

When the conveying module 4 conveys the captured middle frame U-shaped part 8 between the two first cameras 512, the two first cameras 512 are used to detect the opening size of the middle frame U-shaped part 8 by laser flying shooting. By designing the first detection module 51 into the structural form of the above-mentioned two relatively arranged first cameras 512, it is possible to detect the opening size of the middle frame U-shaped part 8 by laser flying shooting, so that the detection result is more accurate. Of course, it can be understood that the design of the first detection module 51 into the method of detecting the opening size by laser flying shooting of the above-mentioned two relatively arranged first cameras 512 is only a preferred example of the embodiment of the utility model. In actual application, it can also be designed into the structural form of other detection modules, as long as the function of opening size detection can be realized, and no more specific limitation is made here.

It should be noted that the above second detection module 52 should also be configured with a controller so that when the U-shaped middle frame part 8 is conveyed to the second detection station 504, the controller can perform the first shape defect detection.

[0103] In some other specific embodiments, referring to Figure 10As shown, the above-mentioned third detection module 53 may specifically include a third detection bracket 531, a third camera 532, and an annular light source 533. Among them, the third detection bracket 531 is arranged at the third detection station 505, and it may specifically but not limitedly be designed in the structure form of a gantry. And the corresponding gantry brackets on both sides can be designed in a height-adjustable structure, such as a structure in which two vertical plates are connected through kidney-shaped holes; the third camera 532 is arranged on the third detection bracket 531 and is used to take pictures of the middle frame U-shaped part 8 located at the third detection station 505 to complete the second shape defect detection; the annular light source 533 is arranged on the third detection bracket 531 to provide illumination for the third camera 532; among them, the second shape defect detection may specifically include surface crack detection and side surface crack detection. By designing the third detection module 53 into the above-mentioned structure form, it is possible to perform surface crack detection and side surface crack detection on the middle frame U-shaped part 8 through taking pictures, making the detection more convenient and the detection result more accurate. Of course, it can be understood that designing the third detection module 53 into the above-mentioned structure form is only a preferred example of the embodiment of the present invention. In the actual application process, it can also be designed into the structure form of other detection modules, as long as it can realize the functions of surface crack detection and side surface crack detection on the middle frame U-shaped part 8, and no more specific limitations are made here. It should be noted that the above-mentioned third detection module 53 should also be configured with a corresponding controller so that when the middle frame U-shaped part 8 is conveyed to the third detection station 505, the controller can perform the second shape defect detection.

Among them, the number of the moving part 5021 and the positioning fixture 503 is not specifically limited. For example, it can be designed in a way referring to Figure 6 As shown in the four-way manner, in the actual application process, it can be designed according to the number of the corresponding second grippers 73 on the sorting module 7. Specifically, referring to Figure 7 and Figure 8As shown in the figure, the above-mentioned positioning fixture 503 may specifically include a positioning base 5031, a clamping fixture 5032, a positioning stopper 5033, a clamping stopper 5034, and a stopper driver 5036.

The position of the positioning stopper 5033 is fixed relative to the positioning base 5031, and the clamping stopper 5034 is slidably matched with the positioning base 5031 along the direction of approaching or departing from the positioning stopper 5033 through a guide rail 5035. For example, referring to Figure 7 As shown in the figure, the positioning stopper 5033 and the clamping stopper 5034 can be specifically designed into a structural form that clamps the inner side of the opening of the middle frame U-shaped part 8. Specifically, the clamping stopper 5034 slides along the direction away from the positioning stopper 5033 through the guide rail 5035 (which is generally also called a micro-motion guide rail due to its small movement stroke) to cooperate with the positioning base 5031, so as to realize the clamping action, and slides along the direction approaching the positioning stopper 5033 to realize the release; and for another example, referring to Figure 8 As shown in the figure, the positioning stopper 5033 and the clamping stopper 5034 can be specifically designed into a structural form that clamps the outer side of the opening of the middle frame U-shaped part 8. Specifically, the clamping stopper 5034 slides along the direction approaching the positioning stopper 5033 through the guide rail 5035 (which is generally also called a micro-motion guide rail due to its small movement stroke) to cooperate with the positioning base 5031, so as to realize the clamping action, and slides along the direction away from the positioning stopper 5033 to realize the release; the stopper driver 5036 is arranged on the positioning base 5031 and is used to drive the clamping stopper 5034 to slide. The stopper driver 5036 can be specifically but not limited to being driven by a cylinder. By designing the positioning fixture 503 into the above structural form, the positioning fixture 503 can better fix the middle frame U-shaped part 8 while not affecting its first shape defect detection, second shape defect detection, and the grasping and sorting actions of the sorting module 7.

Specifically, it may include an X-axis translation motion pair, a Y-axis translation motion pair, and a Z-axis translation motion pair. The combination of the three can achieve three-dimensional translation motion. For example, the Y-axis translation motion pair is arranged on the X-axis translation motion pair, and the Z-axis translation motion pair is arranged on the Y-axis translation motion pair, so that the moving part of the Z-axis translation motion pair can achieve three-dimensional translation motion; the second gripper 73 is arranged on the second three-axis motion mechanism 72, such as on the Z-axis translation motion pair of the second three-axis motion mechanism 72, and the second gripper 73 can grasp and release the middle frame U-shaped part 8; during the actual working process, the second three-axis motion mechanism 72 can drive the second gripper 73 to move from the sorting station to the blanking station 60. It should be noted that the driving methods of the X-axis, Y-axis, and Z-axis of the above second three-axis motion mechanism 72 may but not limited to adopt a combination of one or more driving methods such as screw rod cooperating with servo motor driving, cylinder driving, etc. During the actual application process, it can be selected according to actual needs and will not be more specifically limited here. In addition, in order to facilitate knowing the current position of the second gripper 73 and whether it has grasped the middle frame U-shaped part 8, corresponding sensors with corresponding functions, such as photoelectric sensors, are generally arranged on the second gripper.

[0106] In some other specific implementation schemes, referring to Figure 12As shown in the figure, the above-mentioned blanking bin assembly 6 may specifically include a support platform 61, a bin 62, and a blanking chute 63.

The second chute 632 is used to receive the unqualified middle frame U-shaped parts 8 sorted by the sorting module 7, and the lower end of the second chute 632 is connected to the unqualified bin 622. By designing the blanking bin assembly 6 into the above structural form, the sorted middle frame U-shaped parts 8 can slide down to the corresponding qualified bin 621 and unqualified bin 622 through the first chute 631 and the second chute 632 respectively, which is more convenient to operate, and the gravity free fall is utilized, saving the configuration of the active conveying power of the conveying mechanism. Of course, it can be understood that designing the blanking bin assembly 6 into the structure of the blanking chute 63 arranged obliquely from top to bottom as above is only an example of the embodiment of the present invention. In the actual application process, other active conveying structural forms can also be designed, such as an active conveying conveyor belt, etc., and no more specific limitations are made here.
