Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 2 As shown, a novel automated parts inspection device includes a frame 1, a controller and a rotating table 2 mounted on the frame 1, and a loading unit 3, an inspection unit and an unloading unit arranged sequentially around the rotating table 2; wherein, in this preferred embodiment, the rotating table 2 is an optical special glass turntable, which is driven to rotate by a rotary motor 6.

[0027] The feeding unit 3 includes a motor 28, a pulley 21, a conveyor belt 27, a first guide plate 23, and a second guide plate 26. The motor 28 drives the pulley 21, and the conveyor belt 27 is mounted on the pulley 21. The first guide plate 23 and the second guide plate 26 are arranged on one side of the conveyor belt 27.

[0029] The unloading unit includes at least two workpiece separation devices, each including an air blowing device 7 and a discharge channel 8. The air blowing device 7 is connected to a high-pressure air source. The air blowing device 7 and the discharge channel 8 are respectively arranged correspondingly to each other. The air blowing device 7 is located inside the workpiece channel 10, and the discharge channel 8 is located outside the workpiece channel 10. The end of the workpiece channel 10 extends outward from the rotary table 2. The controller is electrically connected to the above-mentioned loading unit 3, detection unit, and unloading unit. Figure 2 As shown, the inner side of the conveyor belt 27 abuts against the side of the rotary table 2.

[0030] The working principle of a new type of automated parts inspection equipment is as follows: the workpiece enters the feeding unit from the production line, the motor drives the drive pulley to rotate, and drives the conveyor belt to transport the workpiece; when transporting the workpiece, the workpiece passes through the first guide plate 23 from the feeding direction, and the first arc edge 29 of the first guide plate 23 guides the workpiece to the side of the conveyor belt close to the rotary table; the workpiece passes through the second guide plate 26 with the conveyor belt, and the second arc edge 30 of the second guide plate 26 guides and pushes the workpiece to the rotary table, the rotary table is started to rotate, and the rotary table transports the workpieces sequentially through the inspection unit to the unloading unit.

[0031] When a workpiece passes through the detection unit, the material sensor 4 detects whether a workpiece is passing on the conveyor belt. After the material sensor 4 detects the material, it activates the high-precision camera 5 to take a picture of the workpiece. The high-precision camera 5 acquires an image of the workpiece and uploads it to a computer for digital image processing. It extracts some features from the workpiece image, such as shape, quantity, and size, and compares and identifies them according to preset benchmark target parameters to determine whether the workpiece is qualified.

[0032] After passing through the inspection unit, the workpiece is sent to the unloading unit, where the inspected workpieces are sorted and output. The air blowing device 7 is connected to an external high-pressure air source. The air blowing device 7 and the discharge channel 8 are respectively set up to correspond to each other. The air blowing device 7 usually includes a nozzle. The controller controls the high-pressure gas of the corresponding nozzle through the nozzle to blow workpieces with different quality parameters into the corresponding discharge channel, which then distributes them to the sorted workpiece box in the unloading frame 9.

[0033] like Figure 2 As shown, the first guide plate 23 and the second guide plate 26 are respectively mounted above the conveyor belt 27 via guide plate brackets 22, which are arranged along the outer side of the conveyor belt 27.

The first guide plate 23 and the second guide plate 26 are respectively connected to the guide plate bracket 22 through the locking nut 24.

[0035] In this preferred embodiment, the material sensor is an optical fiber material sensor, and the optical fiber material sensor uses an Fs-N181N optical fiber amplifier. The high-precision camera 5 is a CCD high-precision industrial camera, which replaces manual inspection with CCD vision automatic inspection, improving inspection efficiency and quality. The controller is a KV-500 PLC controller, which controls the motor to achieve automatic feeding; the controller obtains the material passing signal through the material sensor 4, activates the high-precision camera to acquire the image of the corresponding workpiece and uploads it to the computer, the computer compares it with preset benchmark target parameters, and the controller activates the corresponding blowing device 7 according to the comparison result, so as to blow workpieces with different quality parameters into the corresponding discharge channel.

[0036] In this preferred embodiment, the workpiece separation device comprises three parts, each with a separate discharge channel 8. These three discharge channels 8 are designated as a qualified channel, an unqualified channel, and a re-inspection channel, respectively. In this preferred embodiment, three discharge channels 8 are provided, each corresponding to an air blowing device 7. The nozzles of the corresponding air blowing device 7 are controlled to spray high-pressure gas, blowing workpieces with different quality parameters into the corresponding qualified, unqualified, and re-inspection channels. From there, the workpieces are distributed from the discharge channels to the workpiece boxes in the qualified, unqualified, and re-inspection channels.

[0037] This invention aims to provide a novel automated parts inspection device. By sequentially arranging a loading unit, an inspection unit, and an unloading unit around a rotating table, it solves the problems of loading, inspecting, and unloading large batches of workpieces on an assembly line. The loading unit's conveyor belt connects to the assembly line equipment, guiding workpieces into the rotating table via a first and second guide plate. The rotating table rotates and transports the workpieces, while the inspection unit inspects each workpiece individually. After inspection, the unloading unit blows workpieces with different quality parameters into corresponding discharge channels, which then distribute them to sorting workpiece bins. This automated inspection device automatically connects workpieces to the inspection equipment, reducing manual loading and thus improving inspection efficiency.
