Description

Technical Field

[0001] This utility model belongs to the field of testing technology, and in particular relates to a part shape testing device. Background Technology

[0002] To ensure the appearance quality requirements of machined parts (cutting, stamping, injection molding, etc.), appearance inspection is required after the parts are formed. With the advancement of technology, industrial camera inspection is gradually replacing manual inspection, thereby improving inspection efficiency.

[0003] For example, patent application CN120253857A discloses an appearance inspection device and method, including: a support unit comprising a detection component and a feeding component, the detection component and the feeding component being driven to move along a first direction, the workpiece to be tested being assembled on the detection component and moving to a designated position under the drive of the detection component; the detection component extending along a second direction perpendicular to the first direction; an image acquisition unit comprising a first transfer component and a camera module, the camera module being mounted on the movable output end of the first transfer component, the camera module being able to move to the position of the detection component under the drive of the first transfer component to perform a first image acquisition of the workpiece to be tested; and a gripping unit comprising a second transfer component and a suction component, the suction component being mounted on the movable output end of the second transfer component, the suction component being able to suction... The device under test (DUT) is picked up and rotated to a specified angle under the drive of the second transfer member to perform a second image acquisition on the DUT. A control unit, communicatively connected to the image acquisition unit, the support unit, and the gripping unit, controls the image acquisition unit to perform image acquisition and controls the actions of the support unit and the gripping unit. During operation, firstly, the DUT is assembled onto the detection assembly. The detection assembly moves the DUT to the detection area. The first transfer member drives the camera module to perform the first image acquisition on the DUT, acquiring images of the first and second detection surfaces of the DUT. Next, the suction assembly, driven by the second transfer member, suctions the DUT and performs the second image acquisition, controlling the third detection surface of the DUT to face the camera module to acquire images of the third detection surface.

[0004] The aforementioned patent document describes a method where a first transfer component drives a camera to rotate, enabling the detection of multiple surfaces of a part. However, using a rotating camera for detection requires adjusting the focus during the process, necessitating both camera rotation and translation. Rapid rotation and translation can reduce the stability of the camera's detection capabilities. Utility Model Content

[0025] In one embodiment of the part shape inspection device of this utility model, the appearance of multiple sides of a part can be inspected. The inspection process does not require CCD camera flipping, which improves the stability of the inspection. Please refer to [link / reference] for details. Figures 1 to 4This embodiment discloses a part shape inspection device, including a frame 100, a loading mechanism 200, a transfer robot 300, a first CCD camera 400, a translation mechanism 500, a positioning device 600, multiple second CCD cameras 700, and a picking robot 800. The loading mechanism 200 and the transfer robot 300 are mounted on the frame 100. A tray 210 is provided on one side of the loading mechanism 200, which receives the parts to be inspected output by the loading mechanism 200. The transfer robot 300 includes a picking component 310 for picking up the parts to be inspected from the tray 210. Specifically, the picking component 310 is a suction nozzle connected to a negative pressure system, using negative pressure to lift the parts from the tray 210. The first CCD camera 400 is mounted on the frame 100 and located at the bottom end of the picking component 310, for inspecting the parts to be inspected at the bottom end of the picking component 310. After the pick-up component 310 picks up the part, it moves to the top side of the first CCD camera 400, thereby completing the bottom inspection of the part. The translation mechanism 500 is mounted on the frame 100, and the moving end of the translation mechanism 500 is equipped with the positioning device 600. The positioning device 600 includes a flip plate 610 and a drive component 620 for flipping the flip plate 610. The flip plate 610 is equipped with a positioning seat 630 for positioning the part to be inspected. Multiple second CCD cameras 700 are arranged along the moving direction of the translation mechanism 500. The picking robot 800 is mounted on the frame 100 and located on one side of the translation mechanism 500.

[0026] Specifically, the feeding mechanism 200 transports the parts to be inspected one by one onto the tray 210. The transfer robot 300 picks up the parts from the tray 210 and moves them to the top of the first CCD camera 400, which inspects the bottom appearance of the parts. After the bottom inspection is completed, the transfer robot 300 positions the bottom surface of the part onto the positioning seat 630. The translation mechanism 500 drives the positioning seat 630 to one side of the second CCD camera 700. Multiple second CCD cameras 700 inspect different sides of the part. For each side inspected, the drive unit 620 drives the flip plate 610 to rotate at a certain angle, thus enabling multi-side inspection of the part. Since the first and second CCD cameras 400 do not need to rotate during inspection, but rather the part rotates, the stability of the inspection is ensured, and the inspection quality is improved.

[0027] Furthermore, refer to Figure 1 , Figure 3 and Figure 4The part shape inspection equipment also includes a positioning camera 900, which is located on the top side of the material tray 210. The material tray 210 is a transparent plate, and a light source 910 is also provided on the bottom side of the material tray 210. In this embodiment, when the part is on the material tray 210, the light source 910 illuminates from the bottom, and the positioning camera 900 can locate the outline position of the part, so that the transfer robot 300 can accurately pick up the part and transfer it to the positioning seat 630.

[0028] Furthermore, refer to Figure 3 and Figure 4 The feeding mechanism 200 includes a vibrator 220, a trough 230, and a cassette 240. The vibrator 220 is mounted on the frame 100, and the trough 230 is mounted on the vibrator 220. One end of the trough 230 extends towards the tray 210, and the other end is connected to the cassette 240. The cassette 240 has a cavity 241 with an inclined surface, and a discharge port 242 at the lower end of the inclined surface. Parts can be stored in the cavity 241 of the cassette 240. The vibrator 220 drives the trough 230 and the cassette 240 to vibrate, causing the parts in the cassette 240 to fall one by one from the discharge port 242 into the trough 230, and then the trough 230 transports the parts one by one onto the tray 210.

[0029] Furthermore, refer to Figure 2 The positioning device 600 further includes two upright plates 640 mounted on a frame, with the flipping plate 610 rotatably connected between the two upright plates 640; the driving component 620 is located on one side of the upright plate 630. Therefore, the upright plates 640 support the flipping plate 610 and the driving component 620. The driving component 620 is a motor mounted on the upright plate 640.

[0030] Furthermore, refer to Figure 2 The flip plate 610 has connecting portions 611 extending from both ends, which are rotatably connected to the upright plate 630. The positioning seat 630 has a positioning surface 631, which coincides with the rotation axis of the connecting portion 611. In this embodiment, when the driving member 620 drives the flip plate 610 to rotate, it ensures the distance between the part and the second CCD camera 700, so that the second CCD camera 700 can perform inspection without moving or with a small distance, thereby improving the efficiency and stability of the inspection.

[0031] Furthermore, refer to Figure 2The positioning device 600 further includes a connecting seat 650, which is located on one side of the flip plate 610. A connecting air pipe 651 is provided inside the connecting seat 650. The first end of the connecting air pipe 651 passes through the bottom of the connecting seat 650, and the second end passes through the flip plate 610. A positioning seat 630 is detachably located at the second end of the connecting air pipe 651. An adsorption pore is provided inside the positioning seat 630, and the adsorption pore communicates with the connecting air pipe 651. The first end of the connecting air pipe 651 is connected to a negative pressure system. When a part is positioned on the positioning seat 630, the negative pressure system creates a negative pressure in the adsorption pore, which fixes the part on the positioning seat 630.

[0032] Furthermore, refer to Figure 2 The connecting air pipe 651 is rotatably connected to the connecting seat 650, and the connecting air pipe 651 is connected to a rotary drive (not shown in the figures). In this embodiment, the rotary drive can drive the connecting air pipe 651 to rotate, thereby driving the positioning seat 630 to rotate, so that any side of the part can be detected.

[0033] Furthermore, the second CCD camera 700 is disposed at the moving end of the linear motion module 10, which is mounted on the frame 100. The distance between the second CCD camera 700 and the part is adjusted by the linear motion module 10, enabling the second CCD camera 700 to accurately detect the part.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
