[0038] The following further describes the implementation manner of the present utility model in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0039] Embodiment 1: As shown in Figure 1 to Figure 6 shown:

[0040] The present utility model provides a side sampling inspection device for a keycap injection molding machine, including a detection support platform 1, a horizontal material receiving structure 2, a vertical material receiving structure 3, and a 3D camera 6;

[0041] At the top of the detection abutment 1, a first cylinder 201 is fixedly installed. The first cylinder 201 is fixedly connected to a first right-angle carrier frame 2012 through a first telescopic rod 2011. At the same time, guide sliding plates 202 are fixedly connected to both sides of the bottom of the first right-angle carrier frame 2012. Guide sliding grooves 2021 are formed on the detection abutment 1, and the guide sliding plates 202 are slidably installed in the guide sliding grooves 2021. At the same time, a fixed support frame 301 is fixedly connected to the top of the detection abutment 1. A second cylinder 302 is fixedly installed on the top of the fixed support frame 301. The driving end of the second cylinder 302 is fixedly connected to a second telescopic rod 3021. At the same time, one end of the bottom of the second telescopic rod 3021 is fixedly connected to a connecting support plate 3022. Right-angle sliding plates 3023 are fixedly connected to both sides of the top of the connecting support plate 3022. A limiting sliding groove 3024 is formed on the inner side wall of the fixed support frame 301, and the right-angle sliding plates 3023 are slidably installed in the limiting sliding groove 3024. At the same time, a second right-angle carrier frame 3025 is fixedly connected to the front end of the connecting support plate 3022. By starting the first cylinder 201 to drive the first telescopic rod 2011 to extend, the first telescopic rod 2011 pushes the first right-angle carrier frame 2012 to move. The guide sliding plates 202 at the bottom of the first right-angle carrier frame 2012 are guided in the guide sliding grooves 2021. Thus, the first right-angle carrier frame 2012 drives the tray 401 to receive materials at the bottom of the mechanical gripper 5. Then, it is detected by the 3D camera 6. After the detection is completed, the first cylinder 201 drives the first right-angle carrier frame 2012 to retract through the first telescopic rod 2011. Then, the second cylinder 302 is started to drive the second telescopic rod 3021 to extend. The second telescopic rod 3021 pushes the connecting support plate 3022 to descend. The right-angle sliding plates 3023 on both sides of the connecting support plate 3022 are limited and guided in the limiting sliding grooves 3024, so that the connecting support plate 3022 drives the second right-angle carrier frame 3025 to receive materials at the bottom of the mechanical gripper 5. By repeating the above operations, horizontal and vertical intermittent alternate material receiving is realized.

[0042] Embodiment 2: On the basis of Embodiment 1, where as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown in the figure, a flipping mechanism 4 is provided on the first right-angle carrier frame 2012 and the second right-angle carrier frame 3025. The flipping mechanism 4 includes a tray 401, a fixed shaft 4011 and a hinge ear 4012. The tray 401 is provided on the first right-angle carrier frame 2012 and the second right-angle carrier frame 3025. Fixed shafts 4011 are fixedly connected to both sides of the tray 401. At the same time, a hinge ear 4012 is fixedly connected to one side inside the tray 401. The flipping mechanism 4 further includes a moving support bar 402, a first hinge frame 4021, a first shaft column 4022, a guide bar 4023 and a guide groove 4024. A moving support bar 402 is provided at one end inside the first right-angle carrier frame 2012 and the second right-angle carrier frame 3025. A first hinge frame 4021 is fixedly connected to the top of the moving support bar 402. At the same time, the first hinge frame 4021 is hinge-connected to the hinge ear 4012 through the first shaft column 4022. Guide bars 4023 are fixedly connected to both sides of the moving support bar 402. Guide grooves 4024 are provided on both sides inside the first right-angle carrier frame 2012 and the second right-angle carrier frame 3025. At the same time, the guide bars 4023 are fitted and slidably installed in the guide grooves 4024. The flipping mechanism 4 further includes a micro cylinder 403 and a third telescopic rod 4031. A third telescopic rod 4031 is fixedly connected to the middle of the moving support bar 402. The third telescopic rod 4031 passes through the first right-angle carrier frame 2012 and the second right-angle carrier frame 3025 and is fixedly connected to the micro cylinder 403 outside. The flipping mechanism 4 further includes a second hinge frame 404, a second shaft column 4041 and a double-headed hinge rod 405. The fixed shaft 4011 is hinge-connected to one end of the double-headed hinge rod 405. Second hinge frames 404 are fixedly connected to both sides of one end of the first right-angle carrier frame 2012 and the second right-angle carrier frame 3025. At the same time, the second hinge frames 404 are hinge-connected to the other end of the double-headed hinge rod 405 through the second shaft column 4041. A mechanical gripper 5 is fixedly installed on one side of the top of the detection support platform 1. A conveying mechanism 7 is provided at one end of the detection support platform 1. At the same time, a receiving box 8 is provided at the bottom of the detection support platform 1. The keycap is placed on the tray 401 through the mechanical gripper 5, and then detected by the 3D camera 6. When the detection is qualified, the keycap is grabbed by the mechanical gripper 5 and placed on the conveying mechanism 7. If it is unqualified, the micro cylinder 403 is started to retract the third telescopic rod 4031, so that the third telescopic rod 4031 pulls the moving support bar 402 to move. Thus, the moving support bar 402 pulls the hinge ear 4012 under the cooperation of the first hinge frame 4021 and the first shaft column 4022. However, the tray 401 forms a flip through the cooperation of the fixed shaft 4011, the second hinge frame 404, the second shaft column 4041 and the double-headed hinge rod 405, and then the keycap on the tray 401 falls into the receiving box 8, realizing automatic material separation.

[0043] Specific usage method and function of this embodiment:

[0044] In the present utility model, first, the first cylinder 201 is started to drive the extension of the first telescopic rod 2011. The first telescopic rod 2011 pushes the first right-angled carrier frame 2012 to move, so that the first right-angled carrier frame 2012 drives the tray 401 to wait for receiving materials at the bottom of the mechanical gripper 5. Then, the injection-molded keycap is placed on the tray 401 of the first right-angled carrier frame 2012 by the mechanical gripper 5. Then, it is identified and detected by the 3D camera 6. When it is qualified, the keycap is picked up by the mechanical gripper 5 and placed on the conveying mechanism 7. If it is unqualified, the third telescopic rod 4031 is retracted by starting the micro cylinder 403, so that the third telescopic rod 4031 pulls the moving strip 402 to move. Thus, the moving strip 402 pulls the articulated ear 4012 under the cooperation of the first articulated frame 4021 and the first shaft column 4022. However, the tray 401 is turned over under the cooperation of the fixed shaft 4011, the second articulated frame 404, the second shaft column 4041 and the double-headed articulated rod 405, so that the keycap on the tray 401 falls into the receiving box 8, realizing automatic material separation. After the detection is completed, the first cylinder 201 retracts. Then, the second cylinder 302 is started, and the second right-angled carrier frame 3025 is driven to descend by the second telescopic rod 3021 to wait for receiving materials. Then, the above operations are repeated to realize automatic detection, abandoning the original manual detection method, which not only reduces the labor cost, but also improves the work efficiency.
