[0030] Please refer to Figures 1 to 10 shown below, which is an embodiment of the present utility model. This embodiment discloses an optical inspection device 100 as shown in Figure 1 and Figure 2 shown below. This embodiment discloses an optical inspection device 100, which includes a workpiece conveyor belt 1, a first transfer mechanism 2 straddling the workpiece conveyor belt 1, a second transfer mechanism 3 parallel to the first transfer mechanism 2, a lower vision inspection mechanism 4 located between the first transfer mechanism 2 and the second transfer mechanism 3, a composite device 5 straddling the workpiece conveyor belt 1, a plurality of material separation units 6 parallel to and located on one side of the workpiece conveyor belt 1, a tray conveyor belt 7 parallel to and located on the other side of the workpiece conveyor belt 1, and a workbench 8 for mounting the above components.

[0031] That is to say, the workpiece conveyor belt 1, the first transfer mechanism 2, the second transfer mechanism 3, the lower vision inspection mechanism 4, the composite device 5, the plurality of material separation units 6, and the tray conveyor belt 7 are all mounted on the workbench 8, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the optical inspection device 100 may omit the plurality of material separation units 6 and the tray conveyor belt 7 according to actual requirements.

[0032] In this embodiment, the workpiece conveyor belt 1 is used to transport at least one tray 11 in a first direction D1. The tray 11 carries a plurality of electronic components 200 and can move between a first position P1, a second position P2, and a third position P3 (along the workpiece conveyor belt 1). Among them, the workpiece conveyor belt 1 generally spans the entire workbench 8 in the first direction D1 in this embodiment. It should be additionally noted that, for the convenience of understanding this embodiment, the number of trays 11 on the workpiece conveyor belt 1 is introduced as one in the following content, but the present utility model is not limited thereto.

[0033] In addition, for the convenience of understanding the transfer structure layout of the optical inspection device 100 in this embodiment, the multiple mechanisms included in the composite device 5 are briefly introduced here first. In this embodiment, the composite device 5 includes a third transfer mechanism 51, an upper vision inspection mechanism 52 mounted on the third transfer mechanism 51, and a circumferential side inspection mechanism 53 mounted on the third transfer mechanism 51; that is to say, the composite device 5 includes transfer functions and multiple inspection functions in this embodiment, but the present utility model is not limited thereto.

[0034] The first transfer mechanism 2, the second transfer mechanism 3, and the composite device 5 (e.g., the third transfer mechanism 51) are arranged parallel to each other and are each mounted on the workbench 8 along a second direction D2 perpendicular to the first direction D1. Among them, the composite device 5 is located on the side of the second transfer mechanism 3 away from the first transfer mechanism 2 (that is, the second transfer mechanism 3 is located between the first transfer mechanism 2 and the composite device 5), and the composite device 5 (e.g., the third transfer mechanism 51) straddles the component conveyor belt 1, a plurality of the material separation units 6, and the tray conveyor belt 7.

[0035] Further, in this embodiment, the first transfer mechanism 2, the second transfer mechanism 3, and the third transfer mechanism 51 each include a track 21, 31, 511 and a gripper 22, 32, 512 movably mounted on the tracks 21, 31, 511. Among them, the tracks 21, 31, 511 are mounted on the workbench 8 and are arranged along the second direction D2, and the grippers 22, 32, 512 are used to acquire a plurality of the electronic components 200. Furthermore, the movement path of the gripper 22 of the first transfer mechanism 2 passes through the first position P1 of the component conveyor belt 1, the movement path of the gripper 32 of the second transfer mechanism 3 passes through the second position P2 of the component conveyor belt 1, and the movement path of the gripper 512 of the third transfer mechanism 51 passes through the third position P3 of the component conveyor belt 1.

[0036] Among them, the upper vision detection mechanism 52 and the circumferential side detection mechanism 53 are optionally arranged along the second direction D2 and mounted on the gripper 512 of the third transfer mechanism 51, so as to be movable relative to the component conveyor belt 1, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the upper vision detection mechanism 52 and / or the circumferential side detection mechanism 53 can also be movably mounted on the track 511 of the third transfer mechanism 51 according to actual needs, so as to be independently movable relative to the component conveyor belt 1; or, the upper vision detection mechanism 52 and the circumferential side detection mechanism 53 can also be each configured with a separate transfer mechanism.

[0037] The above is a general description of the transfer architecture layout of the optical detection device 100 in this embodiment. Next, the remaining architecture details and operating functions of the optical detection device 100 will be introduced. As Figures 3 to 6As shown, the lower vision inspection mechanism 4 is disposed on the movement path of the gripper 32 of the first transfer mechanism 2 and the second transfer mechanism 3; that is to say, the first transfer mechanism 2 is located on one side of the lower vision inspection mechanism 4, and the second transfer mechanism 3 is located on the other side of the lower vision inspection mechanism 4.

[0038] The first transfer mechanism 2 (e.g., the gripper 22) is used to acquire and transfer a plurality of the electronic components 200 from the tray 11 located at the first position P1 along the second direction D2. The lower vision inspection mechanism 4 is used to receive the plurality of the electronic components 200 transferred from the first transfer mechanism 2 and inspect the lower surfaces 201 of the plurality of the electronic components 200. The second transfer mechanism 3 is used to transfer the plurality of the electronic components 200 that have completed the inspection by the lower vision inspection mechanism 4 to the tray 11 located at the second position P2, and accordingly transfer the tray 11 from the second position P2 to the third position P3 through the workpiece conveyor belt 1.

[0039] It should be additionally noted that the specific architecture of the lower vision inspection mechanism 4 can be adjusted and changed according to actual requirements. However, for the convenience of understanding this embodiment, the following content will introduce one feasible architecture of the lower vision inspection mechanism 4, but the present invention is not limited thereto. As Figure 5 shown, in this embodiment, the lower vision inspection mechanism 4 includes a jig 41, a light projector 42 facing the bottom side of the jig 41, a plurality of light receivers 43 corresponding to the light projector 42, and a processing module 44 electrically coupled to the plurality of light receivers 43.

[0040] More specifically, the jig 41 is used to carry a plurality of the electronic components 200 and expose the lower surfaces 201 of the plurality of the electronic components 200 outside the jig 41. The light projector 42 is used to emit a structured light L based on interference fringes toward the lower surface 201 (e.g., a plurality of contacts) of each of the electronic components 200. The plurality of light receivers 43 are used to receive the structured light L reflected by each of the electronic components 200 to obtain a signal. The processing module 44 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 44 can present the three-dimensional surface in the form of point cloud data, and it can be displayed through a screen (not shown in the figure), but the present invention is not limited thereto.

[0041] As Figures 7 to 9As shown, the upper vision inspection mechanism 52 in this embodiment can be used to inspect the upper surfaces 202 of a plurality of the electronic components 200 in the tray 11 located at the third position P3, and the specific structure of the upper vision inspection mechanism 52 can also be adjusted and changed according to actual requirements. However, for the sake of understanding, the structure adopted by the upper vision inspection mechanism 52 in this embodiment is the same as that of the lower vision inspection mechanism 4 in Figure 5 the structure presented, so the following content will not be elaborated.

[0042] The circumferential side inspection mechanism 53 defines an imaging space S outside it, and is used to inspect the circumferential sides 203 of a plurality of the electronic components 200 in the tray 11 located at the third position P3. That is to say, the circumferential side inspection mechanism 53 can directly image the circumferential sides 203 of a plurality of the electronic components 200 located outside the circumferential side inspection mechanism 53 through the imaging space S, so there is no need to be limited to inspecting the circumferential sides 203 of the electronic components 200 one by one, thereby effectively improving the inspection efficiency. In other words, any inspection mechanism that needs to place the electronic components into the space surrounded by the reflector is different from the circumferential side inspection mechanism 53 provided in this embodiment.

[0043] It should be additionally noted that the specific structure of the circumferential side inspection mechanism 53 can be adjusted and changed according to actual requirements. However, for the sake of understanding this embodiment, the following content will introduce one feasible structure of the circumferential side inspection mechanism 53, but the present invention is not limited thereto. As Figure 9 shown, the circumferential side inspection mechanism 53 in this embodiment includes a housing 531, a camera 532 installed inside the housing 531, a conical reflector 533 located inside the housing 531 and below the camera 532, and an annular reflector 534 located inside the housing 531 and arranged corresponding to the conical reflector 533.

[0044] More specifically, the circumferential side inspection mechanism 53 is installed on the third transfer mechanism 51 through the housing 531, and the camera 532 is arranged directly above the conical reflector 533 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 532 defines the imaging space S outside the housing 531 through the reflection of the conical reflector 533 and the annular reflector 534, which is used to inspect the circumferential sides 203 of a plurality of the electronic components 200 in the tray 11 located at the third position P3.

[0045] As described above, when a plurality of the electronic components 200 are carried within the tray 11 and located at the third position P3, the composite device 5 can move relative to the component conveyor 1 (along the second direction D2) so that the upper vision inspection mechanism 52 and the annular side inspection mechanism 53 can be used to inspect the upper surface 202 and the annular side surface 203 of the plurality of the electronic components 200.

[0046] Thus, in this embodiment, the optical inspection device 100 can integrate the upper vision inspection mechanism 52 and the annular side inspection mechanism 53 on the same axis through the composite device 5, which is beneficial to improving the inspection efficiency of the optical inspection device 100 and reducing the overall volume of the optical inspection device 100.

[0047] Furthermore, in order to enable the annular side inspection mechanism 53 to have an optional inspection effect, the annular side inspection mechanism 53 may optionally have at least some of the following features. Among them, the conical reflector 533 includes N first reflectors 5331, the annular reflector 534 includes N second reflectors 5341, and the positions of the N first reflectors 5331 respectively correspond to the positions of the N second reflectors 5341 (for example: the imaging light path P passes through two reflections of each of the first reflectors 5331 and the corresponding second reflectors 5341, and an imaging space S is formed outside the housing 531 by overlapping each other). And N is a positive integer greater than 5 (for example: N is 8). More specifically, when the imaging light path P passes through the annular reflector 534, each of the second reflectors 5341 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] Moreover, the housing 531 defines a central axis C parallel to the height direction H, and the camera 532 is disposed on the central axis C. The conical reflector 533 is N-fold rotationally symmetric with respect to the central axis C, and the annular reflector 534 is also N-fold rotationally symmetric with respect to the central axis C. More specifically, the area surrounded by the plurality of the first reflectors 5331 gradually increases in a direction away from the camera 532, and the bottom of the conical reflector 533 away from the camera 532 surrounds the annular reflector 534, but is not limited thereto.

[0049] For example, in other embodiments not shown in the present utility model, the annular reflector 534 may also be arranged at intervals with the conical reflector 533 along the height direction H; or, the imaging light path P of the ring side detection mechanism 53 may also be defined with the imaging space S located outside the housing 531 through more than two reflections.

[0050] As described above, as Figures 8 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 it is located within the tray 11 at the third position P3. Furthermore, the third transfer mechanism 51 (such as: the gripper 512) can move between the workpiece conveyor belt 1 and the plurality of material separation units 6, and the third transfer mechanism 51 can be used to selectively move at least one of the detected components 200a from the tray 11 located at the third position P3 to one of the plurality of material separation units 6.

[0051] Thus, in this embodiment, the optical detection device 100 can classify the plurality of detected components 200a according to the detection results through the third transfer mechanism 51 and move them to the corresponding material separation units 6. For example: the detected components 200a without any defects, the detected components 200a with defects on the lower surface 201, the detected components 200a with defects on the upper surface 202, and the detected components 200a with defects on the ring side surface 203 can each be stored by one of the material separation units 6.

[0052] It should be added that all the components included in the optical detection device 100 in this embodiment can operate synchronously (for example: when the lower vision detection mechanism 4 detects a batch of electronic components 200, the upper vision detection mechanism 52 and the ring side detection mechanism 53 can synchronously detect another batch of electronic components 200), so as to effectively improve the operation efficiency of the optical detection device 100.

[0053] [Technical effects of the embodiments of the present utility model]

[0054] In summary, the optical detection device disclosed in the embodiments of the present utility model integrates the upper vision detection mechanism and the ring side detection mechanism on the same axis through the composite detection device, so as to facilitate improving the detection efficiency of the optical detection device and reducing the overall volume of the optical detection device.

[0055] Furthermore, the optical detection device disclosed in the embodiment of the present utility model can directly image the circumferential side surfaces of a plurality of the electronic components located outside the circumferential side surface detection mechanism through the imaging space by means of the circumferential side surface detection mechanism. Therefore, 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 utility model, and does not limit the patent scope of the present utility model. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present utility model are included in the patent scope of the present utility model.
