[0025] An apparatus for inspecting and packaging the shape quality of injection molded parts includes an inspection mechanism 5 for inspecting the shape quality of injection molded parts and a packaging mechanism 7 for packaging qualified parts.

[0026] like Figure 1 and Figure 2 As shown, the upstream of the testing mechanism 5 is a vibrating box 1 for receiving and transporting the injection molded parts to be tested.

[0027] The inner wall of the vibrating chamber 1 is equipped with a spiral ascending track. The vibration of the vibrating chamber 1 causes the injection molded part to move upward along the spiral track. The end of the spiral ascending track connects to the screening track 2, which extends to the rotating table 503 of the detection mechanism 5. The screening track 2 utilizes the shape, center of gravity, and edge features of the injection molded part to ensure that the injection molded part moves onto the rotating table 503 in a specific posture (such as lying flat or with a specific side facing down). The end of the screening track 2 is equipped with a guide plate 29, which guides the injection molded part to move along a specific route on the rotating table 503, thereby ensuring that each injection molded part can move onto the detection path.

[0028] like Figure 1 and Figure 3 As shown, the testing mechanism 5 includes a rotating stage 503, a CCD camera 502, and a testing box 501.

[0029] The rotating stage 503 transfers the injection molded part received from the vibration box 1 through the inspection area. The shape image information of the injection molded part acquired by the CCD camera 502 is used as the basis for judging whether the injection molded part is qualified. If the acquired shape image information of the injection molded part is consistent with the shape of the standard injection molded part, the injection molded part is qualified; if the acquired shape image information of the injection molded part has shape quality problems such as gaps, patterns, and warping deformation compared with the shape of the standard injection molded part, the injection molded part is unqualified.

[0030] The rotating stage 503 is equipped with a detection box 501. The detection box 501 plays a protective role in the injection molding part detection process, avoiding interference from external light sources and other factors in the image acquisition process. In addition, the detection box 501 supports the various components of the detection mechanism 5.

[0031] The rotating stage 503 has a transparent surface. CCD cameras 502 are installed above and below the rotating stage 503. The CCD cameras 502 are mounted on the inspection box 501. The transparent rotating stage 503 and the multi-directional CCD cameras 502 help to collect image information of the injection molded parts from all directions.

[0032] Illumination lamps 6 are provided above and below the rotating stage 503. The illumination area of ​​the illumination lamps 6 covers the detection area of ​​the CCD camera 502. The illumination lamps 6 are installed on the detection box 501. The illumination lamps 6 provide sufficient light source and stable brightness for the imaging area, thereby improving image clarity and detail resolution.

[0033] The rotating table 503 is equipped with a first air valve 31 and a second air valve 32 above the corresponding detection position. According to the detection results, the injection molded parts are sorted to different paths. Qualified products are sprayed and sorted by the first air valve 31, while unqualified products are sprayed and sorted by the second air valve 32.

[0034] A counting sensor 30 is installed on the air pipeline of the first air valve 31. The counting sensor 30 counts the number of qualified products by recording the number of times the first air valve 31 sprays.

[0035] The inlet of the qualified product discharge trough 4 corresponds to the spray direction of the first air valve 31. The detection mechanism 5 is equipped with a non-qualified product discharge trough 3. The inlet of the non-qualified product discharge trough 3 corresponds to the spray direction of the second air valve 32. The qualified product discharge trough 4 and the non-qualified product discharge trough 3 guide the sorted injection molded parts to the designated position.

[0036] like Figure 1 , Figure 4 As shown, the packaging mechanism 7 is located at the outlet end of the qualified product discharge trough 4. The packaging mechanism 7 includes a support frame 8 that provides a rigid mounting platform for each component of the packaging mechanism 7, a bag feeding unit 10 that fixes the packaging bag 34 to the end of the qualified product discharge trough 4, and a heat sealing unit 16 that seals the packaging bag 34 located at the end of the qualified product discharge trough 4.

[0037] The bag feeding unit 10 includes a pneumatic clamp 9 for holding and fixing the packaging bag 34 and a robotic arm 27 for transferring the packaging bag 34 to the end of the qualified product discharge chute 4.

[0038] The pneumatic clamp 9 is installed on the support frame 8 and is located below the outlet of the qualified product discharge chute 4. The qualified product discharge chute 4 guides the qualified products to fall into the packaging bag 34 fixed by the pneumatic clamp 9.

[0039] The robotic arm 27 includes a bag-picking robotic arm 26 and a bag-opening robotic arm 25. The bag-picking robotic arm 26 automatically replenishes the packaging bag 34 to the pneumatic clamp 9, and the bag-opening robotic arm 25 ensures that the packaging bag 34 at the end of the qualified product discharge chute 4 remains open, so that qualified products can fall into the packaging bag 34.

[0040] Vacuum suction cups 23 are provided at the ends of the bag-retrieving robotic arm 26 and the bag-opening robotic arm 25. The suction force generated by the vacuum suction cups 23 prevents the packaging bag 34 from falling off the robotic arm 27.

[0041] like Figure 5 and Figure 6 As shown, one side of the bag-picking robotic arm 26 is connected to the output shaft of the rotary cylinder 28. Driven by the rotary cylinder 28, the bag-picking robotic arm 26 rotates. Below the bag-picking robotic arm 26 is a lifting plate 22 that supports the packaging bag 34. The lifting plate 22 is slidably mounted on a third slide rail 24, with the guide rail 24 facing the bag-picking robotic arm 26. Driven by a linear cylinder, the lifting plate 22 moves along the third slide rail 24 towards the bag-picking robotic arm 26. Under the action of the rotary cylinder 28, the bag-picking robotic arm 26 rotates until the vacuum suction cup 23 at its end faces the lifting plate 22. Under the action of the linear cylinder, the lifting plate 22 moves along the third slide rail 24 towards the bag-picking robotic arm 26 until the packaging bag 34 contacts the bag-picking robotic arm 26. The bag-picking robotic arm 26 then adsorbs the packaging bag 34 and resets under the action of the rotary cylinder 28. The lifting plate 22 also resets under the action of the linear cylinder.

[0042] The bag-picking robotic arm 26 and the bag-opening robotic arm 25 are located on both sides of the pneumatic clamp 9. Driven by the third cylinder 20 and the fourth cylinder 21 respectively, the bag-picking robotic arm 26 and the bag-opening robotic arm 25 move towards each other. The bag-picking robotic arm 26 adsorbs the packaging bag 34 and the bag-opening robotic arm 25 move towards the pneumatic clamp 9 at the same time. The bag-picking robotic arm 26 and the bag-opening robotic arm 25 abut against each other at the pneumatic clamp 9 and adsorb the two sides of the packaging bag 34 respectively. The pneumatic clamp 9 then clamps and fixes the packaging bag 34. Subsequently, the bag-picking robotic arm 26 and the bag-opening robotic arm 25 are reset under the action of the third cylinder 20 and the fourth cylinder 21 respectively, thereby opening the packaging bag 34.

[0043] After the bag-picking robotic arm 26, the bag-opening robotic arm 25, and the pneumatic clamp 9 complete the sealing of the packaging bag 34, they repeat their respective operations to realize the continuous execution of the bag picking, fixing, and opening processes, thereby improving production efficiency.

[0044] The heat sealing unit 16 includes a first slide rail 15, a U-shaped plate 14, a heat sealing strip 11, a first cylinder 12, and a second cylinder 13.

[0045] The U-shaped plate 14 is slidably mounted on the first slide rail 15, which is located below the pneumatic clamp 9. The first slide rail 15 provides guidance for the U-shaped plate 14.

[0046] Heat sealing strips 11 are provided on both sides of the U-shaped plate 14. The first cylinder 12 and the second cylinder 13 are respectively provided on both sides of the U-shaped plate 14. The heat sealing strips 11 on both sides of the U-shaped plate 14 move towards each other under the action of the first cylinder 12 and the second cylinder 13. The end of the qualified product discharge trough 4 is located between the two sides of the U-shaped plate 14. Thus, when the heat sealing strips 11 move towards each other, they can heat seal the packaging bag 34 located at the end of the qualified product discharge trough 4.

[0047] Under the action of the fifth cylinder 33, the U-shaped plate 14 can move on the first slide rail 15, thereby driving the heat sealing strip 11, the first cylinder 12 and the second cylinder 13 to move together, avoiding overlap with the working position of the bag picking robot arm 26 during the bag picking process. Furthermore, the heat sealing strip 11 can clamp the packaging bag 34 and transfer it to the preset position through the first slide rail 15, completing the heat sealing of the packaging bag 34 during the clamping and transfer process, saving time and improving work efficiency.

[0048] Below the first slide rail 15, there is a second slide rail 18. A slider 17 slides on the second slide rail 18. A push plate 19 is provided on the side of the slider 17. The slider 17 is driven by a linear cylinder, thereby enabling the slider 17 and the push plate 19 to move along the second slide rail 18. The packaged bag 34, which has been sealed, is held by the heat sealing strip 11 and transferred through the first slide rail 15 to the push plate 19. The push plate 19 pushes the packaged bag 34 to the designated position under the cooperation of the second slide rail 18 and the slider 17.

[0049] The method of using the injection molding part shape quality inspection and packaging device of this utility model is as follows: First, the injection molding parts to be inspected are placed in batches into the vibration box 1. The injection molding parts to be inspected are directionally conveyed to the screening track 2 through the spiral track of the vibration box 1. After posture adjustment, they are guided to the rotating table 503 by the guide plate 29. The CCD camera 502 above and below the rotating table 503 collects multi-angle images with the assistance of the illumination lamp 6. Qualified products are blown into the qualified product discharge chute 4 by the first air valve 31, and unqualified products are sorted into the unqualified product discharge chute 3 by the second air valve 32 and finally into the defective product box. The bag-retrieving robotic arm 26 picks up an empty bag from the lifting plate 22 and works with the bag-opening robotic arm 25 and the pneumatic clamp 9 to fix the opening of the packaging bag 34 to the end of the qualified product discharge chute 4. Qualified products fall into the packaging bag 34 through the qualified product discharge chute 4. After the number of packaging bags 34 reaches the required amount, the heat-sealing strip 11 clamps the packaging bag 34 and moves it laterally along the first slide rail 15 for heat sealing. At the same time, the bag-retrieving robotic arm 26 replenishes new packaging bags 34 and continues to work. After the sealing is completed, the heat-sealing strip 11 is released and reset, and the packaging bag 34 falls to the push plate 19 below the first slide rail 15. The push plate 19 pushes the packaging bag 34 to the designated position.
