Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a vision-based surface quality inspection device for metal stampings. The vision-based surface quality inspection device for metal stampings includes a detection component 100 and a positioning component 200. The detection component 100 can effectively perform visual inspection of the surface of the metal stampings to be inspected, and the positioning component 200 can improve the installation and positioning effect and demolding convenience of the metal stampings.

[0034] Specifically, the detection component 100 includes a support base plate 101, a support rod 102 fixedly connected to the top of the support base plate 101, a mounting top plate 103 fixedly connected to the top of the support rod 102, and an optical imager 104 fixedly connected to the bottom of the mounting top plate 103.

[0035] The base plate 101 provides a supporting foundation for the entire device, maintaining its stability. The support rod 102 provides balanced support for the mounting top plate 103, providing a supporting foundation for its installation. The mounting top plate 103 provides a good fixed installation position for the optical imager 104. During the visual inspection process, the optical imager 104 provides good visual inspection accuracy through optical scanning imaging. This is existing technology and will not be elaborated further here.

[0036] Specifically, the positioning component 200 is disposed on the top of the support base plate 101 and includes a positioning frame 201, a first limiting member 202, a second limiting member 203, a guide member 204, an auxiliary positioning member 205, and a rebound member 208. The positioning frame 201 is disposed on the top of the support base plate 101, the first limiting member 202 is disposed on one side of the positioning frame 201, the second limiting member 203 is disposed on the inner wall of the positioning frame 201, the guide member 204 is disposed on the surface of the positioning frame 201, the rebound member 208 is installed on the other side of the positioning frame 201, and the auxiliary positioning member 205 is disposed on the surface of the rebound member 208.

[0037] The positioning frame 201 is placed on top of the support base plate 101 and contacts its top, so that the user can adjust its position relative to the support base plate 101 at any time, thereby ensuring the coverage of visual inspection. The guide 204 can guide the metal stamping part during insertion by squeezing its two sides, thereby ensuring good movement stability. The first limiting member 202 and the second limiting member 203 can provide a certain limiting effect and deburring effect without affecting the installation efficiency of the metal stamping part. The auxiliary positioning member 205 can provide a certain positioning effect for the metal stamping part after it is fully installed by negative pressure adsorption, thereby ensuring its installation stability. The rebound member 208 can provide a certain demolding assistance when the metal stamping part needs to be demolded.

[0038] Example 2

[0039] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the first limiting member 202 includes a spring-loaded clamping plate 202a and a fixed horizontal plate 202f. The fixed horizontal plate 202f is fixedly connected to the bottom of the positioning frame 201. A first rotating rod 202d is fixedly connected to the surface of the spring-loaded clamping plate 202a. A shaped connecting plate 202c is rotatably connected to the side of the first rotating rod 202d away from the spring-loaded clamping plate 202a. A fixing block 202b is fixedly connected to the side of the shaped connecting plate 202c close to the positioning frame 201. The fixing block 202b is fixedly connected to the surface of the positioning frame 201.

[0041] The top of the fixed horizontal plate 202f is fixedly connected to the bottom of the positioning frame 201 by welding. The fixed block 202b can facilitate the connection between the irregular connecting plate 202c and the positioning frame 201, thereby providing better support and stability for the installation of the irregular connecting plate 202c.

[0042] Specifically, a first torsion spring 202e is sleeved on the surface of the first rotating rod 202d, the first torsion spring 202e is fixedly connected to the surface of the fixed horizontal plate 202f, the first torsion spring 202e is fixedly connected to the surface of the irregular connecting plate 202c, and a first deburring plate 202g is fixedly connected to the top of the fixed horizontal plate 202f.

[0043] The first deburring plate 202g, which is set on top of the fixed horizontal plate 202f, is flush with the bottom of the inner cavity of the positioning frame 201. Therefore, it can make seamless contact with the bottom of the metal stamping part, thus achieving a good scraping and deburring effect during the installation and insertion of the metal stamping part. After the metal stamping part is fully inserted into the inner cavity of the positioning frame 201, the spring clamp 202a will no longer be subjected to the pressure of the metal stamping part. Under the elastic force of the first torsion spring 202e, the spring clamp 202a will be driven to spring back to its original position to position the metal stamping part.

[0044] Specifically, the guide component 204 includes a connecting block 204a, a connecting rod 204b, and a mounting plate 204c. The connecting block 204a is fixedly connected to the surface of the positioning frame 201, the connecting rod 204b is fixedly connected to the surface of the connecting block 204a, a movable connecting rod 204e is sleeved on the surface of the connecting rod 204b, a positioning pulley 204f is rotatably connected to the inner wall of the movable connecting rod 204e, the mounting plate 204c is fixedly connected to one side of the positioning frame 201, a return spring 204d is fixedly connected to the surface of the mounting plate 204c, and the return spring 204d is fixedly connected to the surface of the movable connecting rod 204e.

[0045] During the insertion and installation of the metal stamping, the movable connecting rod 204e will drive the positioning pulley 204f to clamp the two sides of the metal stamping under the elastic force generated by the recovery deformation of the return spring 204d. This can not only convert some of the sliding friction force during the installation of the metal stamping into rolling friction force, thereby improving the ease of installation and insertion of the main body, but also provide a certain limiting effect during its movement.

[0046] Specifically, a support block 207 is fixedly connected to the bottom of the positioning frame 201, and the bottom of the support block 207 contacts the top of the support base plate 101.

[0047] The support block 207 is placed only on top of the support base plate 101. This design allows the user to easily change its position at any time during the overall visual quality inspection process, thereby ensuring the inspection coverage of visual quality inspection.

[0048] Specifically, the second limiting member 203 includes a movable plate 203a, a second deburring plate 203b fixedly connected to one side of the movable plate 203a, a rotating block 203c fixedly connected to the top of the movable plate 203a, a fixed rod 203e movably connected to the inner wall of the rotating block 203c, a second torsion spring 203d sleeved on the surface of the fixed rod 203e, and the fixed rod 203e fixedly connected to the inner wall of the positioning frame 201.

[0049] The inner wall of the rotating block 203c is slidably connected to the fixed rod 203e. Therefore, under the drive of external force, the movable plate 203a can drive the rotating block 203c to rotate around the fixed rod 203e, thereby avoiding obstruction to the insertion of the metal stamping part.

[0050] Specifically, the auxiliary positioning component 205 includes a connecting vertical plate 205a and a positioning plate 205f. A positioning suction cup 205e is fixedly connected to one side of the positioning plate 205f, and an exhaust pipe 205c is fixedly connected to one side of the connecting vertical plate 205a. A threaded sealing cap 205b is threadedly connected to one side of the exhaust pipe 205c, and a connecting hose 205d is connected to one side of the exhaust pipe 205c. The side of the connecting hose 205d away from the exhaust pipe 205c is fixedly connected to the side of the positioning suction cup 205e and communicates with the positioning suction cup 205e.

[0051] The front side of the positioning plate 205f and one side of the positioning suction cup 205e are in contact with the rear side of the metal stamping. When the metal stamping is inserted, the positioning suction cup 205e will form a negative pressure by squeezing out the internal air, thereby fixing the metal stamping. The connecting vertical plate 205a can provide a good installation environment for the exhaust pipe 205c. The connecting hose 205d itself has a certain elasticity and extensibility, so it can adapt to and follow the displacement when the positioning plate 205f is displaced.

[0052] Specifically, the rebound component 208 includes a housing 208a, a positioning hook 208b fixedly connected to one side of the inner wall of the housing 208a, a mounting base 208e fixedly connected to the inner wall of the housing 208a, a sliding groove 208c opened on the top of the mounting base 208e, a limiting protrusion 208d fixedly connected to the inner wall of the sliding groove 208c, a threaded cylinder 208g welded to one side of the mounting base 208e, a threaded extension rod 208h threadedly connected to the inner wall of the threaded cylinder 208g, and an adjusting spring 208f sleeved on the side of the threaded cylinder 208g near the mounting base 208e.

[0053] The adjusting spring 208f can provide a certain elastic force, so that when the limiting protrusion 208d is not restricted, it can quickly drive the threaded cylinder 208g to push the threaded extension rod 208h to drive the positioning plate 205f to pop out, thus ensuring the convenience and speed of demolding.

[0054] Specifically, the threaded extension rod 208h is rotatably connected to one side of the positioning plate 205f.

[0055] One side of the threaded extension rod 208h is movably connected to the positioning plate 205f via a rotating bearing, thereby preventing the rotation of the threaded extension rod 208h from affecting the angular position of the positioning plate 205f.

[0056] Specifically, the positioning component 200 includes a third deburring plate 206, which is fixedly connected to the inner wall of the positioning frame 201.

[0057] There are multiple third deburring plates 206, which are evenly distributed on the inner wall of the positioning frame 201, so that the metal stamping part can make uniform contact and scrape with the third deburring plates 206 during the insertion process, thereby ensuring the deburring effect on the surface of the metal stamping part.

[0058] In use, the operator first selects the metal stamping part to be inspected, then manually presses down the spring clip 202a, and then presses one side of the metal stamping part against the second deburring plate 203b, slowly pushing it inward. During the movement of the metal stamping part, the positioning pulley 204f will adjust its position under the contact force to guide and position it. At the same time, the second deburring plate 203b will drive the rotating block 203c to rotate around the fixed rod 203e through the movable plate 203a, thereby providing a certain amount of movement space for the insertion of the metal stamping part.

[0059] During the installation of the metal stamping parts, the second deburring plate 203b deburrs the top of the metal stamping parts through contact friction. At the same time, the first deburring plate 202g, which is set on the top of the fixed horizontal plate 202f, also deburrs the bottom of the metal stamping parts. During this process, both sides of the metal stamping parts are deburred effectively by the friction of the third deburring plates 206, which are set on both sides of the inner wall of the positioning frame 201.

[0060] Once the metal stamping part is fully inserted into the inner cavity of the positioning frame 201, it will be completely adhered to the positioning suction cup 205e, which will then adhere to it to increase the fixing effect after installation. At the same time, the metal stamping part will no longer squeeze and limit the spring clamp 202a. The spring clamp 202a will be reset under the elastic force generated by the recovery deformation of the first torsion spring 202e and then position the front side of the metal stamping part.

[0061] After the user completes the visual inspection, the user first gently rotates the threaded sealing cap 205b with both hands, causing the exhaust pipe 205c to quickly intake air and release pressure. This prevents the positioning suction cup 205e from adsorbing and positioning the rear of the metal stamping. Then, the user continues to pry the spring-loaded clamping plate 202a downwards and manually pushes the metal stamping inwards. The metal stamping pushes the threaded extension rod 208h backwards through the positioning plate 205f, thereby driving the mounting base 208e to adjust its position through the threaded cylinder 208g. This prevents the positioning hook 208b from positioning the limiting protrusion 208d. Under the elastic force generated by the recovery deformation of the adjusting spring 208f, the mounting base 208e pushes the positioning plate 205f to move through the threaded extension rod 208h, thus pushing the metal stamping to pop out and improving the demolding efficiency of its main body.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
