Description

Technical Field

[0001] This utility model relates to the technical field of workpiece screening equipment, specifically a defective product screening device. Background Technology

[0002] Traditional production lines often rely on robotic arms to pick up or toss defective products: after the inspection unit determines the workpiece's condition, the robotic arm must complete precise positioning, gripping, handling, and placement within a very short cycle time. Although robotic arms have advantages such as high flexibility and the ability to quickly switch product types, their purchase and maintenance costs are high, and they occupy a large amount of space. Under high load operation, arm length, joint acceleration, and end effector wear further limit the achievable rejection speed. To avoid impact loads, robotic arms often need to have a deceleration zone, making it difficult for the actual cycle time to fully keep up with high-speed production lines. Utility Model Content

[0003] The purpose of this invention is to provide a defective product screening device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a defective product screening device, including a support column, a turntable coaxially rotatably connected to the support column, a plurality of industrial cameras for taking pictures of products from different angles are arranged around the turntable, and an exclusion mechanism for discharging defective workpieces from the turntable is provided on the support column.

[0005] Industrial cameras arranged circumferentially on the turntable can capture images of the workpiece from all angles. After the captured images are processed by external analysis equipment, they can be linked with the rejection mechanism to promptly remove workpieces that are deemed unqualified.

[0006] Preferably, the rejection mechanism includes: an air pump located on one side of the support column, the output end of which is provided with a main pipe extending inside the support column; and multiple secondary pipes, each of which is provided with a solenoid valve, one end of which is connected to the main pipe and the other end of which extends to the turntable, for spraying airflow toward the defective workpiece.

[0007] Preferably, the support column is provided with a drive mechanism for driving the turntable to rotate. The drive mechanism includes: a motor, which is mounted on the support column via a bracket, and the output end of the motor is provided with a gear extension; the extension is provided on the turntable and coaxially arranged with the support column, and the extension is provided with a gear ring that meshes with the gear.

[0008] Preferably, the turntable is provided with several sets of baffles to guide the airflow ejected from the secondary pipe along a predetermined trajectory to act on the corresponding workpiece at the workstation, and to prevent the airflow from diffusing and interfering with the workpieces at other workstations.

[0009] Preferably, the turntable has several collection cylinders distributed around its circumference, which are used to receive defective workpieces falling from the turntable after the observation is completed.

[0010] The above design ensures that the rejection of defective workpieces will not affect the remaining qualified workpieces. Since defective parts are identified from different shooting positions, there is no need to reclassify them, thus improving work efficiency. Attached Figure Description

[0019] Example

[0020] Please see Figure 1-3 As shown, the present invention provides a defective product screening device technical solution: a defective product screening device includes a support column 1, a turntable 2 coaxially rotatably connected to the support column 1, a plurality of industrial cameras 3 for taking pictures of products from different angles are provided around the turntable 2, and an exclusion mechanism 4 for discharging defective workpieces from the turntable 2 is provided on the support column 1.

[0021] The industrial camera 3, arranged circumferentially on the turntable 2, can capture images of the workpiece from all directions. After the captured images are processed by an external analysis device, they can be linked with the rejection mechanism 4 to promptly remove workpieces that are deemed unqualified.

[0022] In this embodiment, the external analysis device includes at least a vision controller and a PLC. The vision controller is used to analyze whether the workpiece is qualified, and the PLC is used to receive the judgment issued by the vision controller and operate the air pump 401 and the solenoid valve 404 accordingly.

[0023] The rejection mechanism 4 mainly includes: an air pump 401 and multiple auxiliary pipes 403. The air pump 401 is located on one side of the support column 1. The output end of the air pump 401 is provided with a main pipe 402 extending inside the support column 1. Each auxiliary pipe 403 is provided with a solenoid valve 404. One end of the auxiliary pipe 403 is connected to the main pipe 402, and the other end extends to the turntable 2, which is used to spray airflow toward the defective workpiece.

[0024] In this embodiment, a bracket is further provided on the inner side of the support column 1 to fix the solenoid valve 404, the auxiliary pipe 403, and the main pipe 402.

[0025] The support column 1 is provided with a drive mechanism 5 for driving the turntable 2 to rotate. The drive mechanism 5 mainly includes a motor 501 and an extension 503. The motor 501 is mounted on the support column 1 through a bracket. The output end of the motor 501 is provided with a gear 502. The extension 503 is mounted on the turntable 2 and is coaxially arranged with the support column 1. The extension 503 is provided with a toothed ring 504 that meshes with the gear 502.

[0026] In this embodiment, the structure of the extension 503 is as follows: Figure 2 As shown, its extension surrounds the support column 1 and extends inward without affecting the rotation of the support column 1 and the turntable 2.

[0027] The turntable 2 is equipped with several sets of baffles 6, which are used to guide the airflow ejected from the secondary pipe 403 along a predetermined trajectory to act on the corresponding workpiece at the workstation, and to prevent the airflow from spreading and interfering with the workpieces at other workstations.

[0028] Several collection cylinders 7 are distributed around the circumference of the turntable 2. After the observation is completed, the collection cylinders 7 are used to receive the defective workpieces that fall from the turntable 2.

[0029] The above design ensures that the rejection of defective workpieces will not affect the remaining qualified workpieces. Since defective parts are identified from different shooting positions, there is no need to reclassify them, thus improving work efficiency.

[0030] The working principle of this utility model is as follows:

[0031] The workpiece to be inspected is placed between adjacent baffles 6 on the turntable 2. The motor 501 drives the turntable 2 to rotate around the support column 1. When the workpiece rotates to the inspection station, the industrial camera 3 captures an image in real time, and the image is used by an external vision controller to determine whether it is qualified. If the result is qualified, the motor 501 continues to drive the turntable 2 forward; if it is determined to be unqualified, the turntable 2 moves the workpiece to the preset rejection position. At this time, the PLC first opens the solenoid valve 404 corresponding to the station, and then activates the air pump 401. Compressed air passes through the main pipe 402 and the corresponding auxiliary pipe 403 in sequence, and is guided by the baffles 6 to blow the unqualified workpiece away from the turntable 2 and fall into the collection cylinder 7 below. After rejection is completed, the air circuit is reset, and the turntable 2 continues to the next cycle.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
