[0029] Such as Figures 1 - 4As shown in the figure, an embodiment of the present utility model provides a surface detection device for automotive part production, including a base 1, on which a detection camera 8 is fixed through a bracket. It further includes: an electromagnet 3, a reduction motor 4 is fixed at the bottom of the base 1, the power supply mode of the reduction motor 4 is an external power supply, the output shaft end of the reduction motor 4 movably penetrates through the base 1 and is fixed with a turntable 2, the turntable 2 is rotatably connected inside the base 1, the number of electromagnets 3 is four, and the four electromagnets 3 are all fixed on the turntable 2. The electromagnet 3 is used for magnetically attracting and positioning the parts. The detection camera 8 is located directly above the rear electromagnet 3. Four groups of conductive components 5 are arranged at the bottom of the turntable 2, and the four groups of conductive components 5 respectively correspond to the four electromagnets 3 for controlling the on and off of the electromagnets 3. The electromagnet 3 on the right side is in a power-off state, and the other three electromagnets 3 are all in a power-on state. A support plate 7 is fixedly sleeved on the electromagnet 3, and the support plate 7 is located above the turntable 2; a classification mechanism 6, the classification mechanism 6 includes a fixed frame 61 fixed on the side of the base 1, a servo motor 62 is fixed at the bottom of the fixed frame 61, the output shaft end of the servo motor 62 is fixed with a lever 63, a support plate is fixed on the side of the base 1, and a storage plate 65 is fixed on the support plate. The detection camera 8 transmits the image to the controller, and the controller controls the servo motor 62 to drive the lever 63 to rotate forward or backward.

[0030] As Figure 2 shown, in this embodiment, a reinforcing rib is fixed at the bottom of the turntable 2, and the reinforcing rib is fixed on the circumferential surface of the output shaft of the reduction motor 4. The reinforcing rib is used to improve the connection strength between the turntable 2 and the output shaft of the reduction motor 4.

[0031] As Figure 1 shown, in this embodiment, the four electromagnets 3 are arranged in a circular array with the center of the turntable 2 as the array center. The four electromagnets 3 can store four automotive parts at the same time, thereby improving the detection efficiency of automotive parts.

[0032] As Figure 2 and Figure 3As shown in the figure, in this embodiment, the conductive component 5 includes four square boxes 51 fixed to the bottom of the turntable 2. A movable block 52 is slidably connected inside each square box 51. On both sides of the same movable block 52, a set of springs 54 and a set of conductive heads 53 are respectively fixed. One end of each set of springs 54 away from the movable block 52 is fixedly connected to the side surface of the inner wall of the square box 51 corresponding to this set of springs 54. The conductive heads 53 are electrically connected to the electromagnets 3. The side surface of the inner wall of the base 1 is fixedly provided with a conductive ring 55. The conductive heads 53 are in contact with the inner wall of the conductive ring 55. There is a notch 56 on one side of the conductive ring 55 close to the servo motor 62. When the conductive head 53 moves to the position of the notch 56, it is separated from the conductive ring 55. The number of each set of springs 54 and each set of conductive heads 53 is two. When the conductive head 53 is in contact with the inner wall of the conductive ring 55 under the elastic force of the spring 54, it can supply power to the electromagnet 3, thereby realizing the magnetic adsorption positioning of automotive parts. When the conductive head 53 moves to the position of the notch 56 of the conductive ring 55, the conductive head 53 is separated from the conductive ring 55. At this time, the electromagnet 3 corresponding to this conductive head 53 is powered off, thereby releasing the magnetic adsorption positioning of the automotive parts. After the release, the automotive parts can be removed from this electromagnet 3 by the lever 63.

[0033] As Figure 2 shown in the figure, in this embodiment, on the side of the conductive head 53 away from the spring 54, there is a wavy curved surface one, and on the inner wall of the conductive ring 55, there is a curved surface two adapted to the shape of the curved surface one. By the fitting of the curved surface one and the curved surface two, the contact area between the conductive head 53 and the conductive ring 55 is increased, thereby improving the conductive stability of the electromagnet 3.

[0034] As Figure 2 shown in the figure, in this embodiment, the movable block 52 is a plastic block, and the plastic is a non-conductive material, preventing current from being transmitted to the positions of the square box 51 and the spring 54 and affecting the power supply to the electromagnet 3.

[0035] As Figure 2 shown in the figure, in this embodiment, the support plate 7 is parallel to the upper surface of the turntable 2, ensuring that the upper surface of the support plate 7 is in a horizontal state, thereby realizing the stable support of automotive parts.

[0036] As Figure 2 shown in the figure, in this embodiment, the upper surfaces of the support plate 7 and the storage plate 65 are in the same horizontal plane. When the upper surfaces of the support plate 7 and the storage plate 65 are flush, it ensures the stable movement of automotive parts.

[0037] As Figure 1As shown, in this embodiment, both sides of the lever 63 are provided with a card slot 64, and the two card slots 64 are respectively provided on the front side and the rear side of the lever 63. When the lever 63 rotates, the inner wall of the card slot 64 contacts the surface of the automobile parts. The design of the card slot 64 prevents the automobile parts from being separated from the lever 63 during the process of shifting the automobile parts, so that the lever 63 can stably drive the automobile parts to move, thereby realizing stable classification of the automobile parts.

[0038] like Figure 2 As shown, in this embodiment, the central axis of the lever 63 is perpendicular to the central axis of the servo motor 62, ensuring that the lever 63 is in a horizontal rotation state when the servo motor 62 rotates.

[0039] Working principle: multiple automobile parts are placed one by one on the electromagnet 3 directly in front of the rotating detection camera 8. At this time, the conductive head 53 in the square box 51 at the bottom of the electromagnet 3 fits with the conductive ring 55 under the elastic force of the spring 54, so that the electromagnet 3 is energized. After the electromagnet 3 is energized, the automobile parts placed thereon can be magnetically positioned. Then, the electromagnet 3 is driven by the reduction motor 4 to rotate ninety degrees each time until it is rotated to the bottom of the detection camera 8. The detection camera 8 performs surface detection on the automobile parts on the electromagnet 3. After the detection is completed, it is known whether the automobile parts are qualified. Then, the electromagnet 3 continues to rotate ninety degrees driven by the reduction motor 4. After the rotation, the electromagnet 3 and the corresponding automobile parts are close to the servo motor 62. The electromagnet 3 rotates to the servo motor 62 and drives the conductive head 53 in the square box 51 to rotate to the notch 56 of the conductive ring 55. At this time, the conductive head 53 does not contact the conductive ring 55. Therefore, the electromagnet 3 is powered off to release the magnetic attraction and positioning of the automobile parts, and the servo motor 62 rotates forward or reversely according to the structure of the inspection; when the automobile parts are qualified, the servo motor 62 drives the lever 63 to rotate forward, thereby rotating the qualified automobile parts from the electromagnet 3 and the support plate 7 to the storage plate 65 on the rear side of the servo motor 62; when the automobile parts are unqualified, the servo motor 62 drives the lever 63 to rotate reversely, thereby rotating the unqualified parts to the storage plate 65 on the front side of the servo motor 62; the servo motor 62 and the lever 63 cooperate to realize automatic classification of qualified and unqualified automobile parts, reducing the difficulty of subsequent classification processing; when the electromagnet 3 close to the servo motor 62 rotates ninety degrees again, it rotates back to the front of the inspection camera 8, at this time, the conductive head 53 at the bottom of the electromagnet 3 contacts the conductive ring 55 to realize power supply to the electromagnet 3, and then the automobile parts are placed on the electromagnet 3 and wait for subsequent inspection and classification.

[0040] The present utility model covers any alternatives, modifications, equivalent methods and solutions made to the essence and scope of the present utility model. For the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can also fully understand the present utility model without the description of these details.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
