Description

Technical Field

[0001] This utility model relates to the field of component missing parts detection technology, specifically a component missing parts detection device. Background Technology

[0002] There are generally two existing methods for detecting missing parts: 1. After the parts are assembled onto the product, visual inspection is used to check for any missing parts; 2. After the parts are assembled onto the product, infrared or camera photographs are used for comparison to check for any missing parts. However, visual inspection is prone to worker fatigue, leading to missed or false detections.

[0003] The visual inspection of parts involves three steps: loading, inspection, and unloading. Although some inspection equipment links these three steps together, there is still a problem: there is a certain time interval between the steps, which affects the inspection efficiency. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a component missing detection device.

[0031] Example 1:

[0032] Combination Figure 1-5 As shown, the present invention provides a component missing detection device, including a feeding mechanism 100 and a detection mechanism 200. The feeding mechanism 100 includes a pad 110, a rubber ring 120 embedded in the top of the pad 110, a baffle 130 connected to the top of the pad 110, and a feeding slope 140. The rubber ring 120 is located between the baffle 130 and the feeding slope 140.

[0033] The detection mechanism 200 includes a support frame 210 connected to the top of the platform 110, a cylinder 220 vertically penetrating the support frame 210, a motor 230 connected to the movable end of the cylinder 220, a rotating plate 240 connected to the output shaft of the motor 230, two crossbars 250 embedded in the bottom of the rotating plate 240, a slider 260 slidably connected between the two crossbars 250, two support rods 270 respectively connected to the rotating plate 240 and the slider 260, and a camera 280 penetrating the bottom end of the support rod 270. The two cameras 280 are connected in series and electrically connected to an external image processor.

[0034] Furthermore, the thickness of the rubber ring 120 is less than the thickness of the pad 110, and the top of the rubber ring 120 is flush with the top of the pad 110. This size design facilitates the passage of components through the pad 110.

[0035] Furthermore, the bottom ends of the two support rods 270 are flush, and the bottom ends of the support rods 270 are set as spherical. The structural design of the support rods 270 allows the parts to pass through the rubber ring 120 without causing damage.

[0036] Furthermore, a retaining pad 500 is installed on the top of the rubber ring 120. The outer wall of the retaining pad 500 is in contact with the inner wall of the baffle 130. The retaining pad 500 can prevent the outer wall of the component from being in contact with the baffle 130, so that the support rod 270 on the outside of the rotating plate 240 can rotate smoothly in a circular motion.

[0037] Example 2:

[0038] Combination Figure 4 As shown, based on Embodiment 1, the bottom of the platform 110 is provided with a differentiating mechanism 300. The differentiating mechanism 300 includes a hollow plate 310 connected to the bottom of the support frame 210, a triangular slope plate 320 slidably installed inside the hollow plate 310, and an electric push rod 330 connected between the hollow plate 310 and the triangular slope plate 320. When the tested component is unqualified, the movable end of the electric push rod 330 extends, and then the left slope of the triangular slope plate 320 comes to the bottom of the round opening. When the tested component is qualified, the movable end of the electric push rod 330 retracts, so that the right slope of the triangular slope plate 320 comes to the bottom of the round opening, thereby realizing the differentiating placement.

[0039] Furthermore, the top of the pad 110 has a circular opening, the diameter of which is larger than the diameter of the rubber ring 120. The diameter design of the circular opening allows the components to flexibly rest on the top of the triangular ramp 320.

[0040] Example 3:

[0041] Combination Figure 1 and Figure 5As shown in the above embodiment, a baffle mechanism 400 is provided on one side of the pad 110. The baffle mechanism 400 includes a support plate 410 installed on one side of the pad 110 and a baffle plate 420 detachably connected to the top of the support plate 410. The bottom of the feeding slope 140 is fixedly connected to the top of the support plate 410. The baffle plate 420 is located on the front side of the feeding slope 140. The baffle mechanism 400 can prevent parts on the feeding slope 140 from sliding to the front side of the feeding slope 140.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, multiple assembled parts move along the feeding slope 140 to the top of the rubber ring 120. The operator moves the slider 260 so that the support rod 270 and camera 280 at the bottom of the parts are located in the center position. Then, the cylinder 220 and motor 230 are started. The moving end of the cylinder 220 indirectly pulls the camera 280 directly below it into the part. Then, the motor 230 indirectly drives the two cameras 280 to rotate, realizing all-round shooting of the parts. The captured images are uploaded to an external image processor to realize the detection of parts. When a part is unqualified, the moving end of the electric push rod 330 extends, and then the left slope of the triangular slope plate 320 is located at the bottom of the round opening. Then, the cylinder 220 is started again, so that the two support rods 270 press the parts through the round opening. The unqualified parts slide down along the left slope of the triangular slope plate 320. Then, the moving end of the cylinder 220 retracts, and then the parts on the feeding slope 140 successively come to the top of the rubber ring 120, thereby realizing continuous detection and improving detection efficiency.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
