The following implementation manners will further detail the related technical content of the present utility model, but the disclosed content is not intended to limit the protection scope of the present utility model.

[0029] It should be understood that although terms such as "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another, or one signal from another. Additionally, the term "or" used herein should, depending on the actual situation, possibly include any combination of one or more of the associated listed items.

[0030] Please refer to Figures 1 to 10 as shown, which is an embodiment of the present utility model. As Figure 1 shown, this embodiment discloses an optical detection device 100, which includes a workbench 1, a workpiece conveyor belt 2 installed on the workbench 1, a detection conveyor belt 3 installed on the workbench 1 and located on one side of the workpiece conveyor belt 2, a workpiece transfer mechanism 4 erected on the workbench 1, a lower vision detection mechanism 5 installed on the workbench 1 and corresponding to the workpiece transfer mechanism 4, a composite detection device 6 installed on the workbench 1 and corresponding to the detection conveyor belt 3, a plurality of sorting units 7 installed on the workbench 1, and a sorting transfer mechanism 8 erected on the workbench 1 and corresponding to the plurality of sorting units 7, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the optical detection device 100 may omit the plurality of sorting units 7 and the sorting transfer mechanism 8 according to actual needs.

[0031] In this embodiment, the workpiece conveyor belt 2 is used to transport a plurality of trays 21 in a first direction D1, each of which carries a plurality of electronic components 200. Among them, the workpiece conveyor belt 2 is adjacent to one side of the workbench 1, and the workpiece conveyor belt 2 traverses the entire workbench 1 along the first direction D1. It should be additionally noted that for the convenience of understanding this embodiment, the number of the trays 21 located on the workpiece conveyor belt 2 is introduced as one in the following content, but the present utility model is not limited thereto.

[0032] In addition, the workpiece transfer mechanism 4 and the sorting transfer mechanism 8 are adjacent to each other and arranged in parallel, and the workpiece transfer mechanism 4 and the sorting transfer mechanism 8 are each erected on the workbench 1 along a second direction D2 perpendicular to the first direction D1, so that the workpiece conveyor belt 2 and the workpiece transfer mechanism 4 surround and form a detection area 11, and the workpiece conveyor belt 2 and the sorting transfer mechanism 8 surround and form a sorting area 12.

[0033] Among them, the workbench 1 is configured with the detection conveyor belt 3, the lower vision detection mechanism 5, and the compound detection device 6 within the detection area 11. And within the material separation area 12 of the workbench 1, a plurality of the material separation units 7 are configured (that is, a plurality of the material separation units 7 are located on one side of the workpiece conveyor belt 2 and on one side of the workpiece transfer mechanism 4 away from the compound detection device 6), thereby achieving the effect of properly planning the working space of the workbench 1, but the present invention is not limited thereto.

[0034] The detection conveyor belt 3 is arranged in parallel with the workpiece conveyor belt 2, and the detection conveyor belt 3 is used to convey a jig 31 between a first position P1 and a second position P2 along the first direction D1 (such as: Figure 4 and coating 5). Furthermore, the workpiece transfer mechanism 4 is used to transfer a plurality of the electronic components 200 between the tray 21 located at the default position P0 and the jig 31 located at the first position P1. For example: the workpiece transfer mechanism 4 is used to obtain a plurality of the electronic components 200 from the tray 21 located at the default position P0 and (transfer a plurality of the electronic components 200) to the jig 31 located at the first position P1.

[0035] Furthermore, the lower vision detection mechanism 5 is located below the movement path of the workpiece transfer mechanism 4. In other words, the lower vision detection mechanism 5 is arranged along the second direction D2 between the jig 31 located at the first position P1 and the tray 21 located at the default position P0. In this embodiment, the jig 31 located at the first position P1, the lower vision detection mechanism 5, and the tray 21 located at the default position P0 are arranged in a row in sequence along the second direction D2.

[0036] As described above, as Figures 1 to 4 shown, when a plurality of the electronic components 200 are moving between the tray 21 and the jig 31 through the workpiece transfer mechanism 4 (for example: when the workpiece transfer mechanism 4 is moving a plurality of the electronic components 200 from the tray 21 to the jig 31), the lower vision detection mechanism 5 is used to detect the lower surface 201 of a plurality of the electronic components 200.

[0037] Thus, in this embodiment, the optical detection device 100 can complete the detection of the lower surface 201 synchronously during the transmission process of a plurality of the electronic components 200, so as to effectively reduce the number of conveying times of the optical detection device 100 according to the detection requirements of a plurality of the electronic components 200, thereby being beneficial to improving the detection efficiency of the optical detection device 100 and reducing the overall volume of the optical detection device 100.

[0038] It should be further noted that the specific structure of the lower vision detection mechanism 5 can be adjusted and changed according to actual needs. However, for the convenience of understanding this embodiment, the following content will be introduced with one feasible structure of the lower vision detection mechanism 5, but the present invention is not limited thereto. As Figure 2 and Figure 3 shown, in this embodiment, the lower vision detection mechanism 5 includes a light projector 51, a plurality of light receivers 52 corresponding to the light projector 51, and a processing module 53 electrically coupled to the plurality of light receivers 52.

[0039] More specifically, the light projector 51 is used to emit a structured light L based on interference fringes toward the lower surface 201 (such as a plurality of contacts) of each of the electronic components 200. The plurality of light receivers 52 are used to receive the structured light L reflected by each of the electronic components 200 to obtain a signal. The processing module 53 is used to receive the signal to obtain a three-dimensional surface corresponding to the lower surface 201 of each of the electronic components 200. Furthermore, in this embodiment, the processing module 53 can present the three-dimensional surface in the form of point cloud data, which can be displayed through a screen (not shown in the figure), but the present invention is not limited thereto.

[0040] As Figures 4 to 7 shown, the position of the composite detection device 6 generally corresponds to the second position P2, and the composite detection device 6 includes an upper vision detection mechanism 61, a ring side surface detection mechanism 62, and a detection transfer mechanism 63. Among them, the upper vision detection mechanism 61 and the ring side surface detection mechanism 62 are arranged along the second direction D2, the detection transfer mechanism 63 is installed on the workbench 1 along the second direction D2, and the upper vision detection mechanism 61 and the ring side surface detection mechanism 62 are installed on the detection transfer mechanism 63 to be movable relative to the detection conveyor belt 3 (along the second direction D2), but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the upper vision detection mechanism 61 and the ring side surface detection mechanism 62 can also be respectively configured with separate transfer mechanisms according to actual needs.

[0041] In this embodiment, the upper vision detection mechanism 61 can be used to detect the upper surfaces 202 of the plurality of electronic components 200, and the specific structure of the upper vision detection mechanism 61 can also be adjusted and changed according to actual needs. However, for the convenience of understanding, the structure adopted by the upper vision detection mechanism 61 in this embodiment is the same as the structure presented by the lower vision detection mechanism 5 in Figure 3 Therefore, the following content will not be elaborated further.

[0042] The ring side surface detection mechanism 62 defines an imaging space S outside it for detecting the ring side surfaces 203 of a plurality of the electronic components 200. That is to say, the ring side surface detection mechanism 62 can directly image the ring side surfaces 203 of a plurality of the electronic components 200 located outside the ring side surface detection mechanism 62 through the imaging space S. Therefore, there is no need to be limited to detecting the ring side surfaces 203 of the electronic components 200 one by one, thereby effectively improving the detection efficiency. In other words, any detection mechanism that needs to place the electronic components into the space surrounded by the reflector is different from the ring side surface detection mechanism 62 provided in this embodiment.

[0043] It should be additionally noted that the specific structure of the ring side surface detection mechanism 62 can be adjusted and changed according to actual needs. However, for the convenience of understanding this embodiment, the following content will introduce one feasible structure of the ring side surface detection mechanism 62, but the present utility model is not limited thereto. As Figure 7 shown, in this embodiment, the ring side surface detection mechanism 62 includes a housing 621, a camera 622 installed inside the housing 621, a conical reflector 623 located inside the housing 621 and below the camera 622, and an annular reflector 624 located inside the housing 621 and configured corresponding to the conical reflector 623.

[0044] More specifically, the ring side surface detection mechanism 62 is installed on the detection transfer mechanism 63 through the housing 621, and the camera 622 is arranged directly above the conical reflector 623 along a height direction H perpendicular to the first direction D1 and the second direction D2. Furthermore, the imaging light path P of the camera 622 defines the imaging space S outside the housing 621 through the reflection of the conical reflector 623 and the annular reflector 624, which is used to detect the ring side surfaces 203 of a plurality of the electronic components 200.

[0045] As described above, when the fixture 31 carries a plurality of the electronic components 200 and is located at the second position P2, the composite detection device 6 can move relative to the detection conveyor belt 3 so that the upper vision detection mechanism 61 and the ring side surface detection mechanism 62 can be used to detect the upper surfaces 202 and the ring side surfaces 203 of a plurality of the electronic components 200.

[0046] Thus, in this embodiment, the optical detection device 100 can integrate the upper vision detection mechanism 61 and the ring side surface detection mechanism 62 on the same axis through the composite detection device 6, which is beneficial to improving the detection efficiency of the optical detection device 100 and can reduce the overall volume of the optical detection device 100.

[0047] Furthermore, to enable the ring side surface detection mechanism 62 to have an optional detection effect, the ring side surface detection mechanism 62 may optionally have at least some of the following features. Among them, the conical reflector 623 includes N first reflectors 6231, the annular reflector 624 includes N second reflectors 6241, and the positions of the N first reflectors 6231 respectively correspond to the positions of the N second reflectors 6241 (e.g., the imaging light path P passes through two reflections of each of the first reflectors 6231 and the corresponding second reflectors 6241, and at least partially overlaps outside the housing 621 to form the imaging space S), and N is a positive integer greater than 5 (e.g., N is 8). More specifically, when the imaging light path P passes through the annular reflector 624, each of the second reflectors 6241 can face the imaging space S and form a reflection angle σ between 40 degrees and 50 degrees with respect to the height direction H, but the present invention is not limited thereto.

[0048] Furthermore, the housing 621 defines a central axis C parallel to the height direction H, and the imager 622 is disposed on the central axis C. The conical reflector 623 is N-fold rotationally symmetric with respect to the central axis C, and the annular reflector 624 is also N-fold rotationally symmetric with respect to the central axis C. More specifically, the area surrounded by the plurality of first reflectors 6231 gradually increases in a direction away from the imager 622, and the bottom of the conical reflector 623 away from the imager 622 surrounds the annular reflector 624, but is not limited thereto.

[0049] For example, in other embodiments not shown in the present invention, the annular reflector 624 may also be arranged at intervals along the height direction H with the conical reflector 623; or, the imaging light path P of the ring side surface detection mechanism 62 may also define the imaging space S located outside the housing 621 through more than two reflections.

[0050] As described above, as Figures 7 to 10 shown, each of the electronic components 200 is defined as a detected component 200a after detection on the lower surface 201, the upper surface 202, and the ring side surface 203, and can be placed within the tray 21 of the component conveyor belt 2. Furthermore, the sorting and transferring mechanism 8 can move between the component conveyor belt 2 and the plurality of sorting units 7, and the sorting and transferring mechanism 8 can be used to selectively move at least one of the detected components 200a from the tray 21 located on the component conveyor belt 2 to one of the plurality of sorting units 7.

[0051] Thus, in this embodiment, the optical detection device 100 can classify multiple detected components 200a according to the detection results through the sorting and transfer mechanism 8 and move them to the corresponding sorting unit 7. For example: The detected components 200a without any defects continue to be conveyed by the component conveyor belt 2. One of the sorting units 7 is used to store the detected components 200a with defects on the lower surface 201, another sorting unit 7 is used to store the detected components 200a with defects on the upper surface 202, and yet another sorting unit 7 is used to store the detected components 200a with defects on the circumferential side surface 203.

[0052] In addition, in this embodiment, the component transfer mechanism 4, the detection transfer mechanism 63, and the sorting and transfer mechanism 8 are each described as including a fixed gantry installed on the workbench 1 and a gripper (such as multiple suction nozzles) movably installed on the gantry, and the gripper can be used to simultaneously move multiple electronic components 200 (or multiple detected components 200a), but the present invention is not limited thereto.

[0053] [Technical effects of the embodiments of the present invention]

[0054] In summary, the optical detection device disclosed in the embodiments of the present invention can synchronously complete the detection of the lower surface during the transmission of multiple electronic components, so as to effectively reduce the number of conveying times of the optical detection device according to the detection requirements of multiple electronic components. Moreover, the optical detection device also integrates the upper vision detection mechanism and the circumferential side surface detection mechanism on the same axis through the composite detection device, thereby facilitating the improvement of the detection efficiency of the optical detection device and reducing the overall volume of the optical detection device.

[0055] Furthermore, for the optical detection device disclosed in the embodiments of the present invention, the circumferential side surface detection mechanism adopted can directly capture images of the circumferential side surfaces of multiple electronic components located outside the circumferential side surface detection mechanism through the imaging space, so there is no need to be limited to detecting the circumferential side surfaces of the electronic components one by one, thereby effectively improving the detection efficiency.

[0056] The content disclosed above is only an optional and feasible embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present invention are included in the patent scope of the present invention.
