Description

Technical Field

[0001] The utility model belongs to the field of machine vision guidance, and specifically relates to a ceramic gasket assembly structure based on the principle of vision guidance. Background Art

[0002] With the rapid development of current industrial automation production, realizing the automation and intelligence of the factory production process through various automation technologies and equipment has become a major trend in the upgrading of industrial production. Automation production can greatly improve production efficiency, reduce costs, improve product quality, and reduce labor costs and safety risks.

[0003] Especially in the field of automobile production, various equipment for automated assembly is also developing in a more refined direction. Through standardized automated assembly, automobile parts can be assembled in an efficient and precise manner. With the continuous progress of technology, from the initial installation of simple mechanical devices to the current intelligent assembly of small parts, it demonstrates the important position of automated assembly in automobile production.

[0004] Especially in the assembly of small parts, for example, the Chinese patent with the application number 202321695468.8 introduces an automatic assembly structure of a heater. This design uses an automated assembly method for fine assembly of the heater, but the design is still based on traditional automated assembly procedures, relying entirely on pre-designed fixed procedures and devices for assembly, without an interactive design for secondary adjustment of the processed parts. Such designs are more than sufficient for traditional part assembly, but for more refined assembly requirements, such as the need for adjusting the planar angle during assembly, they cannot provide good assembly effects.

[0005] Therefore, a new assembly design that can perform more intelligent secondary adjustment on fine parts is needed. Summary of the Utility Model

[0006] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a ceramic gasket assembly structure based on the principle of vision guidance. Based on the actual requirements of automated production, the method of the utility model designs an automated assembly structure based on vision guidance technology, and vision guidance technology can achieve high-precision positioning and recognition. After the vision system recognizes the position, posture, and features of the parts through high-precision image processing and feature extraction, precise assembly operations are performed by the rotating structure and the clamping structure. This high-precision positioning and recognition ability can greatly improve the accuracy and consistency of assembly and reduce the error rate caused by human factors.

[0007] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0008] A ceramic gasket assembly structure based on the principle of vision guidance, comprising:

[0009] An image acquisition unit, a turntable and a mounting unit; the image acquisition unit includes: a camera and a carrying base; the carrying base is used to place the ceramic gasket without angle adjustment and provide a standard base plane for image acquisition; on the turntable, there is a fixing part matching the ceramic gasket, and the fixing part can fix the ceramic gasket and cooperate with the turntable to adjust the angle; the mounting unit includes: a clamping jaw and a mounting base; the clamping jaw is arranged above the assembly structure and can move relative to each component; the mounting base is provided with a base for fixing the workpiece for installing the ceramic gasket.

[0010] A light source component is arranged on the top of the carrying base.

[0011] The fixing part is a fitting structure with a shape matching the ceramic gasket.

[0012] The clamping jaw moves through a slide rail arranged above the assembly structure.

[0013] The camera and the clamping jaw are arranged on the same fixed panel, and both the camera and the clamping jaw can move relative to each component.

[0014] A light source component is arranged around the camera.

[0015] The light source component is an annular light source.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The present utility model uses the method of vision guidance to complete the assembly of the ceramic gasket and the housing shaft. On the premise of fixing the ceramic gasket and the housing shaft, first, the image acquisition mechanism is used to collect images respectively, extract the relevant angle information in the images, analyze the installation angle difference between the ceramic gasket and the housing shaft, then use the rotation mechanism to adjust the angle of the ceramic gasket to match the installation angle of the housing shaft, and finally guide the completion of the assembly of the ceramic gasket and the housing shaft.

[0026] The present utility model will be further described below in conjunction with specific embodiments.

[0027] As Figure 1 shown, the present utility model mainly includes an image acquisition part, an angle adjustment part and a workpiece mounting part.

[0028] The overall structure of the present utility model is as Figure 1 shown. Above the main working part is the slide rail 7. On the side of the slide rail 7 is provided a fixed panel 1, and the fixed panel 1 can move left and right along the slide rail 7 under the control of a motor.

[0029] On the side of the fixed panel 1 are respectively provided a gripper 2 and a camera 3. Among them, the gripper 2 is also connected to the fixed panel 1 through a slide rail that can move up and down. Under the control of a motor, the whole gripper 2 can move up and down to realize the function of gripping the workpiece.

[0030] In this embodiment, the workpiece selected is a ceramic gasket used for the automobile engine housing shaft. The overall structure of the gasket is circular. Its special point is that the inner shape of the ring is not a complete circle, but a part of the structure is also a superior arc structure formed by the inner concave of the ceramic gasket ring. The significance of choosing this shape as the inner structure of the ceramic gasket is that it can orient the connecting rod entering the engine housing shaft. Only when it matches the inner circle shape of the ceramic gasket can the connecting rod smoothly pass through the ceramic gasket and enter the engine housing shaft. Therefore, in this embodiment, the gripper 2 selected is a three-jaw structure that can better grip the circular gasket. The specific situation of the ceramic gasket and the gripper 2 is as Figure 2 shown.

[0031] The camera 3 as the image acquisition part is also installed on the fixed panel 1. Its specific structure is as Figure 3As shown in the figure. The camera 3 is set downward, and a light shield is provided around the body of the camera 3, which can effectively block the stray light from above and affect the imaging effect of the camera. The lens of the camera 3 is a macro lens with high shooting precision and a long and narrow shape. It extends from below the overall part of the fixed panel 1 until it is close to the ceramic gasket arranged on the bearing base 4 for shooting. In order to prevent insufficient light, a ring-shaped light source 8 is also provided around the lens at the bottom of the camera 3 to supplement the light required for imaging.

[0032] Another part of the image acquisition part is the bearing base 4. The main function of the bearing base 4 is to provide a relatively good shooting place for the ceramic gasket, so that the camera 3 can better shoot the initial angle of the ceramic gasket and provide an initial value for the subsequent rotation adjustment of the ceramic gasket. Therefore, a fixing part for clamping the periphery of the ceramic gasket is provided at the bottom of the bearing base 4, and its overall structure is a concave bowl-shaped structure, which reduces the influence of the external environment on the ceramic gasket during shooting. And above the bearing base 4, a ring-shaped light source 8 for supplementing the shooting light is also provided. Its specific structure is as Figure 4 shown.

[0033] After the image acquisition work is completed, the ceramic gasket is placed on the device for adjusting the placement angle through the clamping jaw 2, that is, Figure 1 and Figure 5 the turntable 5 shown in the figure. A boss is provided at the center of the turntable 5. The boss is the part for placing the ceramic gasket. According to the specific shape of the ceramic gasket, a fixing part 6 matching the ceramic gasket is provided on the boss. In this embodiment, the ceramic gasket adopted is the circular ring structure described above. Therefore, the fixing part 6 in this embodiment is a fixing rod whose shape matches the center part of the ceramic gasket, and the fixing rod is also arranged at the center of the entire turntable 5. By rotating the turntable 5 at the bottom, the boss and the fixing part 6 are driven to rotate together, and the ceramic gasket placed above the boss will also rotate under the traction of the boss and the engagement force of the fixing part 6. And both the turntable 5 and the front image acquisition part are uniformly controlled by a computer. Therefore, the turntable 5 can adjust the rotation angle required according to the initial angle obtained by the image acquisition part.

[0034] At the back of the turntable 5 is the mounting base 9 for mounting the ceramic gasket. Its structure is as Figure 6 shown. The outer structure of the mounting base 9 is a fastener, and the structure of the fastener is the same as that of the workpiece on which the ceramic gasket needs to be mounted. Its main function is to fasten the workpiece, which is convenient for the clamping jaw 2 to place the ceramic gasket with adjusted angle to the specified mounting position.

[0035] The overall working process of the present utility model is as follows: First, place the ceramic gasket to be adjusted into the bearing base 4. Subsequently, obtain the initial posture and angular data of the ceramic gasket through the camera 3. Then, place the ceramic gasket onto the turntable 5 part by the gripper 2. After adjusting the angle by the turntable 5, send the ceramic gasket to the installation base 9 for the final fastening process.

[0036] The solution mainly provided by the present utility model is to adjust the angle of small fittings based on the principle of vision guidance. The ceramic gasket selected in the embodiment is a good workpiece for demonstrating the solution. However, the core innovation point of this solution does not lie in the solution for adjusting the angle of the ceramic gasket with a specific shape in the embodiment, but a new automated production design concept. Through the technical inspiration obtained from the components with corresponding functions in this specification, for example, only making limited changes to the shape of the gripper or the shape structure of the image acquisition part without changing the specific technical effects achieved by them should also fall within the protection scope of this application.
