Description

Technical Field

[0001] The utility model relates to the technical field of valve detection, in particular to a valve appearance detection device. Background Technique

[0002] The valve is a key component in the valve train of internal combustion engines (including gasoline engines and diesel engines), and its structure and function are crucial for the performance of the engine. The main function of the valve is to control the intake and exhaust of the cylinder, ensuring that fresh air or a mixture of air and fuel can enter the cylinder, and at the same time allowing the exhaust gas after combustion to be discharged. The valve faces extreme temperatures and pressures during operation, so it is necessary to ensure the production quality of the valve. By performing an appearance inspection on the valve, damage on the valve surface, such as cracks, pits, and grooves, can be detected, and the dimensions of the valve can be measured to avoid affecting the performance and sealing of the valve.

[0003] Existing valves usually consist of parts such as a sealing head, a guide rod, a catheter, a spring, and a locking clip. Among them, the sealing head and the guide rod are an integral structure. The appearance inspection of the valve usually focuses on the sealing head and the guide rod. Currently, valve appearance inspection devices are usually based on machine vision technology and perform inspection and analysis through main components such as an image acquisition device, a lighting system, an image processing software, a mechanical positioning and conveying system, and a control and feedback system. However, in order to perform appearance inspection on all parts of the valve, the position of the valve needs to be continuously adjusted during the appearance inspection process, which is very inconvenient during the operation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a valve appearance detection device to solve the problem in the above background technique that currently on the market, in order to perform appearance inspection on all parts of the valve, the position of the valve needs to be continuously adjusted during the appearance inspection process, which is very inconvenient during the operation.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A valve appearance detection device includes a detection device main body. A detection camera and a lighting lamp are installed on the detection device main body. The detection device main body is provided with a first valve positioning plate and a second valve positioning plate with the same structure. Limiting grooves corresponding to each other in position are respectively opened on the outer sides of the first valve positioning plate and the second valve positioning plate. A first clamping roller and a second clamping roller are respectively rotatably installed on both sides of the limiting groove between the first valve positioning plate and the second valve positioning plate. A first transmission gear and a second transmission gear are respectively fixed to the bottoms of the first clamping roller and the second clamping roller. A driving gear fixed to the first transmission gear is further provided below the first clamping roller. A transmission gear belt is externally meshed and connected between the driving gears, and a linkage gear belt is externally meshed and connected between the first transmission gear and the second transmission gear corresponding to each other in position.

[0006] Preferably, a box body is provided outside the main body of the detection device, and a mounting cover for motor installation is fixedly screwed at the bottom of the box body, and the upper end of the mounting cover is rotationally supported at the bottom of the second valve positioning plate.

[0007] Preferably, the box body is provided with an opening structure that is snap-connected to the first valve positioning plate and the second valve positioning plate, and one side of the first valve positioning plate and the second valve positioning plate is located outside the box body.

[0008] Preferably, a fixing plate is fixedly welded to the side surface of the mounting cover, and an L-shaped mounting plate is fixedly screwed to the upper end of the fixing plate.

[0009] Preferably, the detection cameras are installed on both sides of the inner side of the mounting plate, and the detection cameras are respectively oriented towards the first valve positioning plate and the second valve positioning plate, and the lighting lamps are respectively installed on the sides of the detection cameras.

[0010] Preferably, connecting rods are evenly spaced and fixedly screwed between the first valve positioning plate and the second valve positioning plate, and a rotating shaft connected to the motor through a coupling is also fixedly penetrated through the middle between the first valve positioning plate and the second valve positioning plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: After the valve is positioned, the valve appearance detection device can automatically rotate to adjust the detection position, and avoid the obstruction of the detection caused by the positioning structure during the valve detection process, improving the speed of valve appearance detection and being more efficient.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: a valve appearance detection device, including a detection device main body 1, a detection camera 6 and a lighting lamp 4 are installed on the detection device main body 1. There are a first valve positioning plate 8 and a second valve positioning plate 9 with the same structure on the detection device main body 1. There is a box body 2 outside the detection device main body 1, and an installation cover 10 for motor installation is fixedly screwed at the bottom of the box body 2, and the upper end of the installation cover 10 is rotatably supported at the bottom of the second valve positioning plate 9. This structure can cover and fix the detection area through the box body 2, so that the work of the detection camera 6 and the lighting lamp 4 is not disturbed. The second valve positioning plate 9 is rotatably supported through the installation cover 10. There is an opening structure on the box body 2 that is clamped with the first valve positioning plate 8 and the second valve positioning plate 9, and one side of the first valve positioning plate 8 and the second valve positioning plate 9 is located outside the box body 2. This structure enables the first valve positioning plate 8 and the second valve positioning plate 9 to sequentially rotate out the limit grooves 15 when rotating synchronously, so as to facilitate the loading and unloading of the valve outside the box body 2. Limit grooves 15 with corresponding positions are respectively opened on the outer sides of the first valve positioning plate 8 and the second valve positioning plate 9. A first clamping roller 5 and a second clamping roller 7 are respectively rotatably installed on both sides of the limit groove 15 between the first valve positioning plate 8 and the second valve positioning plate 9. A rubber structure is arranged on the outer circles of the first clamping roller 5 and the second clamping roller 7, which plays a role in stabilizing the positioning of the valve and avoids scratching the valve appearance. A fixing plate 11 is welded and fixed on the side of the installation cover 10, and an L-shaped installation plate 3 is fixedly screwed at the upper end of the fixing plate 11. This structure enables the installation plate 3 to be stably installed relative to the installation cover 10 through the fixing plate 11, enables the reliable installation of the detection camera 6, and performs appearance detection on the valve that moves to the area of the detection camera 6. First transmission gears 502 and second transmission gears 701 are respectively fixed at the bottoms of the first clamping roller 5 and the second clamping roller 7, and a driving gear 501 fixed to the first transmission gear 502 is also arranged below the first clamping roller 5. The detection camera 6 is installed on both sides of the inner side of the installation plate 3, and the detection camera 6 is respectively oriented towards the first valve positioning plate 8 and the second valve positioning plate 9, and the lighting lamp 4 is respectively installed on the sides of the detection camera 6. This structure enables the detection camera 6 on the side to perform side shooting detection on the valve during the rotation process, and the detection camera 6 above performs head detection on the valve. Since the limit grooves 15 are opened on the first valve positioning plate 8 and the second valve positioning plate 9, the blocking area during valve appearance detection is reduced, so that the valve can be respectively detected on the side and at the end during the vertical movement process, reducing the inconvenience caused by replacing the valve fixing position for appearance detection at different positions. At the same time, when the valve is performing side appearance detection, the valve also rotates through the clamping cooperation of the first clamping roller 5 and the second clamping roller 7, so that all parts on the side of the valve can be subjected to appearance shooting detection. The lighting lamp 4 is used to increase the brightness and ensure the appearance detection quality. There is an external meshing connection of a transmission gear belt 12 between the driving gears 501.An external meshing connection with a linkage gear belt 13 is provided between a first transmission gear 502 and a second transmission gear 701 which are in corresponding positions. Connecting rods 14 are evenly spaced and screwed and fixed between a first valve positioning plate 8 and a second valve positioning plate 9. Moreover, a rotating shaft 16 connected to a motor through a coupling is fixedly penetrated through the middle between the first valve positioning plate 8 and the second valve positioning plate 9. This structure enables one of the first clamping rollers 5 to be rotationally driven by the motor under the positioning of the second valve positioning plate 9, so that the first clamping roller 5 can drive other first clamping rollers 5 to rotate synchronously through the meshing of a driving gear 501 and a transmission gear belt 12. The first transmission gear 502 drives the second transmission gear 701 to rotate through the meshing of the linkage gear belt 13, realizing the rotation of the second clamping roller 7, and further enabling the valve to rotate between the second clamping roller 7 and the first clamping roller 5.,

[0020] Working principle: When using this valve appearance detection device, first, when the detection device main body 1 performs an appearance detection process on the valve, the valve is inserted into the limiting grooves 15 in sequence between the linkage gear belt 13 from outside the box body 2 to ensure that the valve is clamped between the first clamping roller 5 and the second clamping roller 7. The first valve positioning plate 8 and the second valve positioning plate 9 are connected and fastened through the connecting rods 14, so that the first valve positioning plate 8 and the second valve positioning plate 9 rotate under the drive of the rotating shaft 16, enabling the valve to enter the box body 2 in sequence. Since one of the first clamping rollers 5 rotates under the drive of the motor, other first clamping rollers 5 rotate synchronously under the linkage of the driving gear 501 and the transmission gear belt 12. The first transmission gear 502 drives the second clamping roller 7 to rotate through the meshing of the linkage gear belt 13 and the second transmission gear 701, causing the valve between the second clamping roller 7 and the first transmission gear 502 to rotate. Therefore, when the valve rotates to the position of the detection camera 6, the end appearance detection is performed by the detection camera 6 above, and the side appearance detection is performed by the detection camera 6 on the side. After the detected valve is removed after rotating out of the box body 2, the qualified products and unqualified products are placed separately, reducing the inconvenience caused by continuously adjusting the position in the traditional valve appearance detection, ensuring the speed of the valve appearance detection. The mounting plate 3 is stable relative to the mounting cover 10 through the fixing plate 11, ensuring the reliable use of the detection camera 6. The lighting lamp 4 provides sufficient lighting for the use of the detection camera 6, thus completing a series of operations.,

[0021] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.,
