Description

Technical Field

[0001] This utility model relates to the field of automotive parts surface appearance defect detection technology, and more specifically, to an automotive parts surface inspection tooling. Background Technology

[0002] Cars have become a common means of transportation in daily life, and in recent years, the number of cars owned has increased rapidly, which has directly stimulated the prosperity and development of the automobile manufacturing industry. With the development of the automobile manufacturing industry, competition within the industry has gradually intensified. In order to ensure good economic benefits, it is necessary to strictly control the quality of automobile parts and ensure the safety performance and comfort of the produced cars.

[0003] Automotive parts processing comprises the various units that make up the entire automotive parts processing industry and the products that serve automotive parts processing. With the increasingly fierce competition in the automotive parts processing market, the growing awareness of environmental protection, and the continuous upgrading and application of technology, more and more attention is being paid to the quality of automobiles. Among them, after the windshield of an automotive part is processed, its appearance surface quality needs to be inspected to reject unqualified products (unqualified products are specifically parts with defects, scratches, and bubbles on the surface).

[0004] The current surface inspection process for automotive parts is as follows:

[0005] (1) First, the car parts are manually fixed on the inspection table, and then the upper surface of the car parts is photographed and the defects are identified by a vision camera located above the inspection table.

[0006] (2) After the inspection of the upper surface is completed, the clamping of the car parts is manually released, and then the parts are flipped over. After the flipping is completed, the car parts are fixed again.

[0007] (3) The vision camera takes another picture of the lower surface of the car parts and identifies whether there are any defects;

[0008] (4) Manually remove the fixing and unload the material;

[0009] The above-mentioned inspection process requires manual assistance to flip the parts over and repeatedly fix and unfix them, thus the automation level of the inspection process for surface defects of automotive parts needs to be improved. Utility Model Content

[0010] The purpose of this invention is to solve the problems mentioned in the background art and to propose a surface inspection fixture for automotive parts.

[0011] The technical solution adopted by this utility model to solve its technical problem is:

[0012] A surface inspection fixture for automotive parts includes a mounting bracket, a horizontal telescopic component, a vertical telescopic component, a first vision camera, a second vision camera, a placement plate, through holes, a sealing assembly, and a clamping assembly.

[0013] The horizontal telescopic components, vertical telescopic components, first-view camera, and clamping components are all mounted on the mounting frame;

[0014] The second vision camera is connected to a horizontal telescopic component;

[0015] The placement plate is connected to a vertical telescopic component and has through holes and sealing components that cooperate with the through holes. The size of the through holes is larger than that of the first vision camera.

[0016] Furthermore, the clamping assembly includes a first telescopic member, a clamping plate, and a rubber pad. The first telescopic member is symmetrically arranged on the mounting frame and is connected to the clamping plates that are distributed opposite each other. The clamping plates are provided with rubber pads.

[0017] The above solution can automatically clamp and fix automotive parts and release them by using clamping components, thereby reducing the labor intensity of manual operation.

[0018] Furthermore, the sealing assembly includes a second telescopic member and a sealing plate. The second telescopic member is disposed at the bottom of the placement plate and is connected to a sealing plate that mates with the through hole.

[0019] The above solution involves sealing the through holes when visually inspecting the upper surface of automotive parts, and keeping the through holes open when visually inspecting the lower surface of automotive parts to avoid obstructing the passage of the first visual camera and subsequent imaging.

[0020] Furthermore, the mounting bracket is symmetrically provided with slide rails that slide in cooperation with the placement plate.

[0021] Furthermore, a control box is installed on the mounting bracket, and a voice prompt device is installed on the control box.

[0022] The above solution can automatically broadcast the results of surface inspection of automotive parts through a voice prompt device.

[0023] Furthermore, the horizontal telescopic member is connected to a mounting plate, on which a second vision camera and a fan are arranged in a front-to-back manner with the second vision camera, and the fan is higher than the second vision camera.

[0024] The above solution uses a fan to blow away dust and impurities adhering to the placement plate in a timely manner, thereby improving the cleanliness of the placement plate surface and ensuring the stable operation of the visual imaging and inspection process.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] Compared to existing technologies, this device only requires loading and unloading when visually inspecting the upper and lower surfaces of automotive parts. It does not require fixing the automotive parts or flipping them over. It automates the clamping and unclamping of automotive parts. At the same time, with the help of two vision cameras, it can automatically and accurately complete the appearance defect detection of the upper and lower surfaces without flipping them over. The surface inspection tooling for automotive parts has a better effect and the degree of automation is improved. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0033] like Figure 1 and Figure 2 As shown, a surface inspection fixture for automotive parts includes a mounting bracket 1, a horizontal telescopic component 2, a vertical telescopic component 3, a first vision camera 4, a second vision camera 5, a placement plate 6, a through hole 7, a sealing assembly, and a clamping assembly.

[0034] The horizontal telescopic component 2, the vertical telescopic component 3, the first vision camera 4, and the clamping assembly are all mounted on the mounting frame 1;

[0035] The second vision camera 5 is connected to a horizontal telescopic component 2 (further optimized, the mounting bracket 1 is symmetrically provided with slide rails that slide in cooperation with the placement plate 6, the slide rails are shown in the figure but are not labeled).

[0036] The placement plate 6 is connected to a vertical telescopic member 3 and has a through hole 7 and a sealing component that cooperates with the through hole 7. The size of the through hole 7 is larger than that of the first vision camera 4.

[0037] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the clamping assembly includes a first telescopic member 8, a clamping plate 9, and a rubber pad 10. The first telescopic member 8 is symmetrically arranged on the mounting frame 1 and is connected to the clamping plates 9 which are distributed opposite each other. The clamping plate 9 is provided with a rubber pad 10.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the sealing assembly includes a second telescopic member 11 and a sealing plate 12. The second telescopic member 11 is disposed at the bottom of the placement plate 6 and is connected to the sealing plate 12 that cooperates with the through hole 7.

[0039] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, a control box 13 is installed on the mounting bracket 1, and a controller is installed inside the control box 13. A voice prompt device 14 is also installed on the control box 13.

[0040] It should be noted that the horizontal telescopic component 2, the vertical telescopic component 3, the first vision camera 4, the second vision camera 5, the first telescopic component 8, and the second telescopic component 11 are all electrically connected to the controller.

[0041] The working process of this utility model is as follows:

[0042] First, place the automotive parts on the placement plate 6 (in this application, the automotive parts specifically undergoing surface testing are windshields, therefore the through-hole 7 will not affect the placement of the windshield, and the initial height of the placement plate 6 is as per the instruction manual). Figure 1 As shown in the figure, the controller then controls the clamping component to work, which can automatically limit the position of the windshield to avoid shaking during the subsequent surface inspection process. At this time, the sealing component seals the through hole 7.

[0043] Then, the upper surface of the car parts can be photographed using the second vision camera 5 (the initial position of the second vision camera 5 is shown in the attached description). Figure 1 As shown in the image, the captured image is then transmitted to the controller for comparison. Images of the upper surface that meet quality standards have already been uploaded to the controller. The system can then determine whether the upper surface of the automotive part has defects, categorized into two situations:

[0044] (1) If there is a defect on the upper surface, the controller controls the voice prompt 14 to issue an instruction "quality unqualified". Then the controller controls the clamping assembly to release the clamp and unload the material.

[0045] (2) If there are no defects on the upper surface, the clamping assembly remains clamped, and then the controller controls the vertical telescopic component 3 to drive the placement plate 6 to descend (at this time, the sealing component releases its obstruction of the through hole 7). When the first vision camera 4 passes through the through hole 7, the placement plate 6 stops moving downward. This downward movement height is also preset in the controller (the vertical and accurate guidance of the placement plate 6 can be achieved through the slide rail, as detailed in the attached instruction manual). Figure 2 As shown in the figure, the controller then controls the horizontal telescopic component 2 to retract, thereby driving the second vision camera 5 to move away from the shooting frame of the first vision camera 4. Then the first vision camera 4 can take a picture of the lower surface of the car parts. Similarly, qualified images of the lower surface are uploaded to the controller in advance.

[0046] If there are no defects on the lower surface of the automotive parts, the controller will control the voice prompt device 14 to issue an instruction "quality qualified"; otherwise, it will prompt "quality unqualified". After completing the visual inspection of both sides of the automotive parts, the clamp will be automatically released to achieve unloading.

[0047] Compared to existing technologies, this device only requires loading and unloading when visually inspecting the upper and lower surfaces of automotive parts. It does not require fixing the automotive parts or flipping them over. It automates the clamping and unclamping of automotive parts. At the same time, with the help of two vision cameras, it can automatically and accurately complete the appearance defect detection of the upper and lower surfaces without flipping them over. The surface inspection tooling for automotive parts has a better effect and the degree of automation is improved.

[0048] In other embodiments, such as Figure 3 As shown, the horizontal telescopic member 2 is connected to a mounting plate (the mounting plate is not numbered in the figure). The mounting plate is equipped with a second vision camera 5 and a fan 15 distributed in front of and behind the second vision camera 5. The fan 15 is higher than the second vision camera 5. In this embodiment, the fan 15 can blow away the dust and impurities attached to the placement plate 6 in a timely manner, thereby improving the cleanliness of the surface of the placement plate 6 so that the visual imaging and detection process can be carried out stably.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
