Description

Technical Field

[0001] This utility model relates to the field of injection molded part inspection, specifically a CCD inspection device for the shape of injection molded parts. Background Technology

[0002] Injection molded parts are a type of plastic product manufactured through injection molding. They are widely used in various industries such as automotive, electronics, medical, home appliances, and packaging. The production process involves melting, injecting, cooling, and demolding of plastic raw materials, ultimately forming parts with specific shapes and functions. CCD inspection of injection molded parts involves capturing product images with a CCD industrial camera and using an image processing system to analyze information such as pixel distribution and brightness, thereby achieving automated and high-precision inspection of shape defects (such as scratches, cracks, color differences, deformations, etc.) and dimensional deviations.

[0003] However, most existing CCD inspection devices for injection molded parts lack the ability to flip the parts. Since injection molded parts may have multi-faceted defects (such as scratches on the back, internal burrs, and sidewall deformation), a fixed-view CCD camera can only capture images of a single surface, which can easily lead to an increased rate of missed inspections. Defective products may flow into the next process or into the hands of customers, causing quality accidents. Furthermore, if the injection molded part has grooves, holes, or cantilever structures, a fixed view may cause some areas to be obscured, making it impossible to image completely. This requires adding a manual re-inspection step, reducing the efficiency advantage of automated inspection. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, most CCD inspection devices for injection molded parts lack the function of flipping the injection molded parts. Since injection molded parts may have multi-faceted defects, such as scratches on the back, internal burrs and side wall deformation, but a fixed-view CCD camera can only capture images of a single surface, it is easy to lead to problems such as increased false negative rate. This utility model proposes a CCD inspection device for injection molded parts.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a CCD detection device for the shape of injection molded parts, including a detection frame, the detection frame being L-shaped, the inner cavity of the detection frame being provided with a first conveying device and a second conveying device, a pushing mechanism being provided on one side of the detection frame, and a flipping mechanism being provided in the inner cavity of the detection frame.

[0006] The flipping mechanism includes a rotating shaft, the surface of which is rotatably connected to the inner cavity of the testing frame. One end of the rotating shaft is fixedly connected to a connecting plate, and the surface of the rotating shaft is fixedly connected to a first rotating plate. There are multiple first rotating plates, and each of the first rotating plates has a storage slot on one side. There are four storage slots. A driving mechanism is provided on one side of the testing frame.

[0007] Preferably, the drive mechanism includes a mounting frame, one side of which is fixedly connected to one side of the detection frame. A second motor is fixedly mounted on one side of the mounting frame, the output end of the second motor is fixedly connected to a first transmission plate, and a lever is fixedly connected to one side of the first transmission plate.

[0008] Preferably, a second rotating plate is fixedly connected to one side of the connecting plate, and a slot is provided on one side of the second rotating plate. The number of slots is four, and the surface of the lever cooperates with the four slots.

[0009] Preferably, the pushing mechanism includes a support plate, one side of which is fixedly connected to one side of the detection frame, and a first motor is fixedly installed on one side of the support plate, with a rotating rod fixedly connected to the output end of the first motor.

[0010] Preferably, the inner cavity of the testing frame is slidably connected to a push rod, one end of the push rod is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to one side of a rotating rod.

[0011] Preferably, one end of the push rod is fixedly connected to a limiting plate, one side of the limiting plate abuts against the inner wall of the detection frame, and the other side of the limiting plate is fixedly connected to a rubber layer.

[0012] Preferably, the top of the testing frame is fixedly connected to a support frame, and there are two support frames, each with an industrial camera fixedly installed in its inner cavity.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a first conveyor and a second conveyor in cooperation to ultimately transport injection molded parts from an L-shaped inspection frame. The first conveyor transports the injection molded parts to one side, where they are first inspected by an industrial camera. The parts are then pushed into the second conveyor by a pushing mechanism. A flipping mechanism is located within the second conveyor. Multiple first rotating plates are connected as a single unit by a rotating shaft and are evenly spaced between the conveyor belts of the second conveyor. A drive mechanism rotates the rotating shafts along the inner cavity of the inspection frame, simultaneously rotating the first rotating plates. The injection molded parts can then proceed to the next stage of the inspection process. The injection molded part is placed into the corresponding storage slot. When the first rotating plate rotates 180 degrees each time, it can flip the injection molded part in one of the storage slots. Since the first rotating plate and the conveyor belt in the second conveying device are misaligned, the injection molded part can come into contact with the conveyor belt in the second conveying device after being flipped and then conveyed again. Finally, the other side is inspected by the industrial camera corresponding to the second conveying device. This solves the problem that most injection molded part shape CCD inspection devices lack the function of flipping the injection molded part. Since the injection molded part may have multi-faceted defects, such as scratches on the back, internal burrs and side wall deformation, but the fixed-view CCD camera can only capture the image of a single surface, it is easy to lead to the problem of increased missed detection rate.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a CCD detection device for the shape of injection molded parts. (Refer to...) Figures 1 to 5 A CCD inspection device for the shape of injection molded parts includes an inspection frame 1, which is L-shaped. The inner cavity of the inspection frame 1 is provided with a first conveying device 2 and a second conveying device 3. The top of the inspection frame 1 is fixedly connected to a support frame 4, and there are two support frames 4. An industrial camera 5 is fixedly installed in the inner cavity of each support frame 4. A pushing mechanism 6 is provided on one side of the inspection frame 1, and a flipping mechanism 7 is provided in the inner cavity of the inspection frame 1.

[0025] The flipping mechanism 7 includes a rotating shaft 701, the surface of which is rotatably connected to the inner cavity of the inspection frame 1. A connecting plate 702 is fixedly connected to one end of the rotating shaft 701, and a first rotating plate 703 is fixedly connected to the surface of the rotating shaft 701. Multiple first rotating plates 703 are present, and four placement slots 704 are provided on one side of each first rotating plate 703. A drive mechanism 8 is provided on one side of the inspection frame 1. The L-shaped inspection frame 1 provides the main support for the injection molded part's CCD inspection device. The first conveying device 2 and the second conveying device 3 cooperate to ultimately convey the injection molded part from the L-shaped inspection frame 1. The first conveying device 2 conveys the injection molded part to one side, first passing it through the industrial camera 5 corresponding to the first conveying device 2 for inspection. The injection molded part is then pushed into the second conveying device 1 by the pushing mechanism 6. The device 3 and the flipping mechanism 7 are set in the second conveying device 3. Multiple first rotating plates 703 are connected into one unit by rotating shaft 701 and are equally spaced between the conveyor belts of the second conveying device 3. The rotating shaft 701 can be driven to rotate along the inner cavity of the detection frame 1 by the driving mechanism 8. When the rotating shaft 701 rotates, it can drive the first rotating plates 703 to rotate. The injection molded parts can enter the corresponding placement slots 704 respectively. When the first rotating plate 703 rotates 180 degrees each time, it can flip the injection molded parts in one placement slot 704. Since the first rotating plate 703 is misaligned with the conveyor belt in the second conveying device 3, the injection molded parts can contact the conveyor belt in the second conveying device 3 after being flipped and then be conveyed again. Finally, the other side is detected by the industrial camera 5 corresponding to the second conveying device 3.

[0026] Reference Figure 4 and Figure 5 The drive mechanism 8 includes a mounting frame 801. One side of the mounting frame 801 is fixedly connected to one side of the detection frame 1. A second motor 802 is fixedly mounted on one side of the mounting frame 801. A first transmission plate 803 is fixedly connected to the output end of the second motor 802. A lever 804 is fixedly connected to one side of the first transmission plate 803. A second rotating plate 805 is fixedly connected to one side of the connecting plate 702. A slot 806 is provided on one side of the second rotating plate 805. There are four slots 806. The surface of the lever 804 cooperates with the four slots 806. Through the drive mechanism 8, the second motor 802 in the drive mechanism 8 can drive the first transmission plate 803 to rotate. When the first transmission plate 803 rotates, it can drive the lever 804 to rotate. Each rotation of the lever 804 can insert into one slot 806. Through the cooperation of the lever 804 and the slot 806, the second rotating plate 805 can drive the rotating shaft 701 and the first rotating plate 703 to rotate 90 degrees each time.

[0027] Reference Figures 1 to 3The pushing mechanism 6 includes a support plate 601, one side of which is fixedly connected to one side of the detection frame 1. A first motor 602 is fixedly mounted on one side of the support plate 601. A rotating rod 603 is fixedly connected to the output end of the first motor 602. A push rod 604 is slidably connected to the inner cavity of the detection frame 1. A connecting rod 605 is rotatably connected to one end of the push rod 604. The other end of the connecting rod 605 is rotatably connected to one side of the rotating rod 603. A limiting plate 606 is fixedly connected to one end of the push rod 604. One side of the limiting plate 606 abuts against the inner wall of the detection frame 1. A rubber layer 607 is fixedly connected to the other side of the limiting plate 606. Through the set pushing mechanism 6, the first motor 602 can drive the rotating rod 603 to rotate. Through the swinging cooperation of the rotating rod 603 and the connecting rod 605, the push rod 604 can be driven to move back and forth. The reciprocating push rod 604 can push the injection molded parts one by one to the flipping mechanism 7. The limiting plate 606 can limit the position of the reciprocating push rod 604. The rubber layer 607 can improve the anti-slip effect on the one hand, and on the other hand, it can minimize the hard contact between the push rod 604 and the injection molded parts.

[0028] Working principle: The first conveyor 2 transports the injection molded parts to one side. First, the parts are inspected by the industrial camera 5 corresponding to the first conveyor 2. The first motor 602 drives the rotating rod 603 to rotate. Through the swinging action of the rotating rod 603 and the connecting rod 605, the push rod 604 reciprocates. The reciprocating push rod 604 pushes the injection molded parts one by one to the flipping mechanism 7. The flipping mechanism 7 is located in the second conveyor 3. Multiple first rotating plates 703 are connected as one unit by rotating shafts 701, and the multiple first rotating plates 703 are evenly spaced between the conveyor belts of the second conveyor 3. The second motor 802 in the drive mechanism 8 drives the first transmission plate 803 to rotate. As plate 803 rotates, it drives lever 804 to rotate. Each rotation of lever 804 allows it to be inserted into a slot 806. Through the cooperation of lever 804 and slot 806, the second rotating plate 805 can drive rotating shaft 701 and the first rotating plate 703 to rotate 90 degrees each time. The injection molded parts can then enter the corresponding storage slots 704. When the first rotating plate 703 rotates 180 degrees each time, it can flip the injection molded parts in a storage slot 704. Since the first rotating plate 703 is misaligned with the conveyor belt in the second conveying device 3, the injection molded parts can come into contact with the conveyor belt in the second conveying device 3 after being flipped and then conveyed again. Finally, the other side is inspected by the industrial camera 5 corresponding to the second conveying device 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
