Description

Technical Field

[0001] This application relates to the field of inspection device technology, and in particular to a visual inspection device for plastic gears. Background Technology

[0002] Plastic gears are injection molded using an injection molding machine. During the forming process, various factors can cause defects such as material shortages or bulges on the surface of the plastic gears, necessitating quality inspection. Existing gear inspection devices include a vibratory feeder, a transparent turntable, a screening component, and an inspection component. The vibratory feeder sequentially transports multiple gears onto the transparent turntable, which then transports them to the inspection component's station. The inspection component includes an upper inspection head and a lower inspection head, located at the upper and lower ends of the transparent turntable, respectively, to inspect the upper and lower surfaces of the gears. However, defects can also occur on the circumference of the gears. Since the inspection component does not include a step for inspecting the circumference of the gears, the overall pass rate of the produced gears is low. Utility Model Content

[0003] The purpose of this invention is to provide a visual inspection device for plastic gears, addressing the shortcomings and deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a transparent turntable, a feeding vibratory feeder, a first inspection station, a second inspection station, and an unloading station. The feeding vibratory feeder, the first inspection station, the second inspection station, and the unloading station are arranged along the rotation direction of the transparent turntable. The second inspection station includes a transverse inspection machine and a drive assembly. The collecting end of the transverse inspection machine corresponds to the upper end of the transparent turntable. The drive assembly can rotate the gear located at the second inspection station.

[0006] Preferably, the driving assembly includes a clamping cylinder, a rotating cylinder, and a driving cylinder. The clamping cylinder is installed at the output end of the rotating cylinder, the rotating cylinder is located at the output end of the driving cylinder, and the driving cylinder is arranged vertically upward.

[0007] Preferably, the first inspection station includes an upper inspection machine and a lower inspection machine, which are placed vertically and located at the upper and lower ends of the transparent turntable, respectively.

[0008] Preferably, a first screening station is provided between the first detection station and the second detection station. The first screening station includes a first pushing cylinder and a first waste box. The first pushing cylinder is placed horizontally and faces the outside of the transparent turntable. The first waste box is located on the outside of the transparent turntable. The first pushing cylinder and the first waste box correspond to each other.

[0009] Preferably, a second screening station is provided between the second detection station and the unloading station. The second screening station includes a second push cylinder and a second waste box. The second push cylinder is placed horizontally and faces the outside of the transparent turntable. The second waste box is located on the outside of the transparent turntable. The second push cylinder and the second waste box correspond to each other.

[0010] Preferably, the unloading station includes an unloading plate and a receiving frame. The receiving frame is located outside the transparent turntable, the unloading plate is placed horizontally, and the outer end of the unloading plate corresponds to the receiving frame.

[0011] Preferably, a sensor is provided at the lower end of the clamping cylinder.

[0012] In summary, the beneficial technical effects of this application are as follows:

[0013] When the gear inspection device is working, the feeding vibratory feeder transports the gears one by one to the transparent turntable. The turntable then moves the gears to the first inspection station, where the upper and lower inspection machines inspect the upper and lower surfaces of the gears. When a defective product is detected, the first push cylinder at the first screening station pushes the defective gear, causing it to fall into the first waste box. Then, driven by the transparent turntable, the gear is transported to the second inspection station. Afterward, the drive cylinder is activated, causing the clamping cylinder and rotating cylinder to descend. The clamping cylinder then... The cylinder clamps the gear, and then the rotary cylinder drives the clamping cylinder to rotate, so that the circumference of the gear is exposed to one end of the transverse inspection machine in turn, so that the circumference of the gear can be inspected. After that, the clamping cylinder releases the gear, and the drive cylinder lifts the clamping cylinder and the rotary cylinder. Then, the second push cylinder of the second screening station pushes the unqualified gear, so that the unqualified gear falls into the second waste box. Then, the qualified gear is driven by the transparent turntable to contact the unloading plate. After that, the qualified gear falls into the receiving box under the guidance of the unloading plate, which improves the pass rate of the produced gear. Attached Figure Description
