[0044] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0047] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0048] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components.

It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0051] Figure 1 is a schematic structural diagram of a joint detection device 300 according to an embodiment of the present disclosure. Figure 2 It is a schematic structural diagram of a joint detection device 300 from another angle according to an embodiment of the present disclosure.

[0052] The utility model provides a connector detection device 300, which is used to detect type-c connectors and other components. The connector detection device 300 may include components such as a turntable 310, a fixture 320, a first detection component 330, a second detection component 340 and a third detection component 350.

[0053] The turntable 310 is driven to rotate; in a specific embodiment, the turntable 310 is rotatably disposed on a turntable bracket, which can be fixed to an object such as the ground, and the turntable 310 can be connected to a driving device such as a motor, thereby allowing the turntable 310 to rotate.

[0054] In a preferred embodiment, a through hole is opened in the middle of the turntable 310, and the fixing plate 370 is arranged at the upper end of the fixing column, and the lower end of the fixing column passes through the through hole of the turntable 310 and is fixed to the turntable bracket or fixed to the ground, so that the fixing plate 370 can be located above the turntable 310 and is in a stationary state. In other words, the fixing plate 370 of the present disclosure does not affect the rotation of the turntable 310.

[0055] The jig 320 of the present disclosure is provided in multiple numbers. In a specific embodiment, the jig 320 is provided in six numbers. The six jigs 320 are distributed at equal intervals along the circumference of the turntable 310. The joint can be held in the jig 320, and as the turntable 310 rotates, the joint is carried by the jig 320 and reaches different workstations.

[0056] Specifically, six workstations can be formed by six fixtures 320 , and these six workstations can be a loading station, a first inspection station, a second inspection station, a third inspection station, a first unloading station, and a second unloading station, respectively.

[0057] At the loading station, the joints can be delivered to the jig 320 by a loading device (such as a robotic arm or a motion platform, etc.) and held by the jig 320. When the loading is completed, the turntable 310 is controlled to rotate about 60°, so that the jig 320 moves from the current station to the next station, so that the joints at each station can be processed synchronously.

[0058] Figure 3 is a schematic structural diagram of a fixture 320 according to an embodiment of the present disclosure.

[0059] like Figure 3 As shown, the fixture 320 of the present disclosure includes a base plate 321 and a fixing portion 322 fixed to the base plate 321 , wherein the fixing portion 322 has a groove 323 , and at least a portion of the joint is disposed in the groove 323 .

[0060] In the present disclosure, the groove 323 is substantially in the shape of a cuboid, and has a length direction, a width direction, and a depth direction.

[0061] The groove 323 has an opening 324, wherein the opening 324 is formed in the length direction of the groove 323 and away from the center of the turntable 310. More preferably, when the fixture 320 is fixed to the turntable 310, the groove 323 can be located outside the turntable 310, and accordingly, the opening 324 is further away from the center of the turntable 310.

[0062] The size of the opening 324 is slightly smaller than the size of the joint, and the joint is fixed by the joint contacting the side wall of the opening 324 with pressure. In a preferred embodiment, the fixing portion 322 can be made of elastic materials such as rubber or silicone. Of course, the fixing portion 322 of the present disclosure can also be made of materials such as rubber or silicone only in the portion near the groove.

[0063] At the same time, the length of the groove 323 can be smaller than or equal to the size of the joint in this direction. At this time, when the joint is held by the fixture, part of the joint is located inside the groove 323 and part of it is located outside the groove 323.

[0064] Moreover, the dimension of the groove 323 in the width direction is larger than the dimension of the joint in this direction, so that the side wall of the groove 323 is spaced apart from the joint, so that the third detection component can effectively take pictures of the two ends of the joint in the width direction, that is, the two arc surfaces of the joint, and realize the detection of the arc surfaces of the joint.

[0065] In the present disclosure, a positioning hole is provided on the base plate 321, and at least a portion of the positioning column 381 of the positioning device 380 can be inserted into the positioning hole so that the fixture 320 is positioned; that is, the number of the positioning devices 380 is also set to 6, that is, each workstation is provided with a positioning device 380, so that the positioning of the fixture 320 at the current workstation can be achieved through the positioning device 380.

[0066] In a preferred embodiment, the side wall of the positioning hole can be provided with an elastic material, so that the positioning post 381 can be more easily inserted into the positioning hole through the deformation of the elastic material. That is to say, during actual positioning, the positioning post 381 can be inserted into the hole of the elastic material, and at this time, there is elastic material between the positioning post 381 and the side wall of the positioning hole.

[0067] The structures of the first detection component 330 , the second detection component 340 , the third detection component 350 , and the fourth detection component 360 will be described in detail below.

[0068] Specifically, the first detection component 330 is used to detect the joint of the first detection station in the first direction, and the first direction can be a vertical direction, that is, the depth direction mentioned above, or the thickness direction of the joint; in the present disclosure, the first detection component 330 includes a first camera 331, and the first camera 331 can be installed on the first vertical plate 333 through the first bracket 332, and the first vertical plate 333 can be fixed to the upper end of the first column 334, and the lower end of the first column 334 can be fixed to the fixed plate 370; accordingly, the lens of the first camera 331 of the present disclosure is set to face downward to capture an image from above the joint and detect the upper surface of the joint. Moreover, a polarizer is provided between the lens of the first camera 331 and the fill light device to reduce reflections on the surface of the workpiece.

[0069] Moreover, the first detection component 330 of the present invention also includes a fill light device 336, which is preferably a ring-shaped fill light. The fill light device is fixed to the first vertical plate 333 through a first connecting plate 335. A through hole is provided on the first connecting plate 335. The optical axis of the first camera 331 coincides with the axis of the through hole of the first connecting plate 335, and also coincides with the axis of the ring-shaped fill light.

[0070] When the first detection component 330 is working, the annular fill light can be turned on to supplement light to the joint, and then the first camera 331 takes pictures, so that the joint can be detected more accurately.

[0071] In addition, the first camera 331 is located above the first connecting plate 335 , and the annular fill light is located below the first connecting plate 335 , so that the light generated by the annular fill light will not affect the first camera 331 .

[0072] The second detection component 340 is used to detect the joint of the second detection station in a second direction, and the second direction can be the above-mentioned length direction; the second detection component 340 includes a second camera, and the second camera is used to take an image from the side of the joint to detect the side of the joint. In the present disclosure, the optical axis of the second camera is arranged to coincide with the above-mentioned first direction. The second detection component 340 has a similar structure to the first detection component 330, and will not be described one by one in the present disclosure.

[0073] The third detection component 350 is used to detect the joint of the third detection station in the third direction; wherein the third detection component 350 includes a third camera 351, and the third camera 351 is used to capture an image from the oblique upper side of the joint to detect the arc surface of the joint. In the present disclosure, the optical axis of the third camera 351 can be perpendicular to the first direction mentioned above, and form an angle greater than 45-60° with the horizontal plane; in this case, the third direction is the optical axis direction of the third camera. The structure of the third detection component 350 is similar to that of the first detection component 330, and will not be described in detail in the present disclosure.

[0074] The joint detection device 300 of the present disclosure also includes a fourth detection component 360, which is used to detect the bottom surface of the joint. Preferably, the fourth detection component 360 includes a fourth camera 361, and the optical axis of the fourth camera 361 is vertically arranged, so that the product that has been detected by the first detection component 330, the second detection component 340 and the third detection component 350 and is judged to be qualified can be removed from the fixture 320 by the handling device, and then the handling device is controlled to move and the joint is located above the fourth detection component 360. Accordingly, the fourth detection component 360 takes a picture of the bottom surface of the joint to detect whether there are defects on the bottom surface of the joint.

[0075] The joint detection device disclosed in the present invention enables the joint to be placed in multiple positions through a rotating turntable, and detects each surface of the joint one by one at the multiple positions to determine whether the joint is damaged. Accordingly, the damaged joint will be unloaded from the waste channel, the normal structure will be loaded by the loading device, and the joint will be installed on the circuit board to realize the manufacturing of the final product.
