Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing technology, specifically to an engine cylinder head anti-rust system. Furthermore, it also relates to an engine production line. Background Technology

[0002] In the manufacturing process of vehicle engines, the engine cylinder head, as a key component, directly affects the engine's service life and reliability due to its rust prevention treatment. The rust prevention process for engine cylinder heads primarily involves spraying rust-preventive paint to isolate them from air and moisture, preventing oxidation and corrosion of the metal parts. Currently, the rust prevention process mainly involves spraying / applying rust-preventive paint to the sides of the engine cylinder head, forming a rust-preventive coating. Existing rust-preventive spraying equipment typically cannot spray / apply rust-preventive paint to the top of the engine cylinder head. The top of the engine cylinder head is used for installation and connection with the valve cover, and a sealing ring is installed between the top of the engine cylinder head and the valve cover to improve the sealing of the installation. Therefore, there is a gap between the top of the engine cylinder head and the valve cover, and the top of the engine cylinder head also has an exposed machined surface. When the engine is in normal operation, if it gets wet from rain or moisture, rust is likely to occur on the top of the engine cylinder head, affecting the sealing between the engine cylinder head and the valve cover, leading to oil leakage and consequently a decrease in engine performance. Utility Model Content

[0003] The purpose of this invention is to overcome the technical problem of easy corrosion of the top of the engine cylinder head in the prior art, and to provide an engine cylinder head anti-rust system.

[0004] To achieve the above objectives, this utility model provides an engine cylinder head rust prevention system, comprising: a paint supply device, a position sensing device, and a collaborative robot. The paint supply device includes a paint dispensing component for supplying rust-preventive paint to the engine cylinder head. The position sensing device is used to detect the position of the engine cylinder head. The collaborative robot is connected to the paint dispensing component. The collaborative robot is configured to control the paint dispensing component to move along a predetermined trajectory on the end face where the engine cylinder head and valve cover are mounted when the position sensing device detects the position of the engine cylinder head.

[0005] Through the above technical solution, in the engine cylinder head anti-rust system of this utility model, when the position sensing device detects the position of the engine cylinder head, the collaborative robot starts working. The collaborative robot can move along a predetermined trajectory on the end face where the engine cylinder head and valve cover are installed. The collaborative robot is connected to a paint dispensing component of a paint supply device. As the collaborative robot moves along the predetermined trajectory, the paint dispensing component also moves along the predetermined trajectory, delivering anti-rust paint to the engine cylinder head. Thus, by moving along the predetermined trajectory, the paint dispensing component sprays / applies anti-rust paint onto the end face of the engine cylinder head where it is installed with the valve cover, such as a predetermined position on the top of the engine cylinder head, forming an anti-rust paint coating at that predetermined position. This reduces the risk of rust formation on the top of the engine cylinder head after the engine is exposed to rain or moisture, while improving the appearance quality of the engine. Moreover, through the coordinated operation of the position sensing device, the paint supply device, and the collaborative robot, the anti-rust process of the engine cylinder head is automated, improving the efficiency of the anti-rust work.

[0006] In some embodiments, the rust prevention system further includes a blocking device configured to prevent the engine cylinder head from moving when the position sensing device detects the position of the engine cylinder head.

[0007] In some embodiments, the blocking device includes a support member and a first lifting unit disposed on the support member, wherein the first lifting unit is capable of preventing the engine cylinder head from moving when it is in a raised state.

[0008] In some embodiments, the rust prevention system further includes a positioning device, which includes a second lifting unit configured to control the engine cylinder head to move up and down when the position sensing device detects the position of the engine cylinder head.

[0009] In some embodiments, the positioning device further includes a support plate that is tractively connected to the second lifting unit and a plurality of support columns disposed on the support plate, the support columns being used to support the tray of the engine cylinder head.

[0010] In some embodiments, the positioning device further includes a positioning pin disposed on the end of the support column, the positioning pin being used to engage with a pin hole on the tray.

[0011] In some embodiments, the rust prevention system further includes a vision recognition component disposed on the collaborative robot, the vision recognition component being capable of identifying the model of the engine cylinder head.

[0012] In some embodiments, the paint supply device further includes a paint storage unit for storing the anti-rust paint and communicating with the paint dispensing component, and a controller for controlling the paint storage unit to deliver the anti-rust paint to the paint dispensing component.

[0013] In some embodiments, the anti-rust paint includes a first component paint and a second component paint, and the paint storage unit includes a first paint storage component for storing the first component paint and a second paint storage component for storing the second component paint. The controller can control the first paint storage component and the second paint storage component to respectively deliver the first component paint and the second component paint to the paint dispensing component, and make the mixing ratio of the first component paint and the second component paint reach a predetermined value.

[0029] In the manufacturing process of vehicle engines, the engine cylinder head 5 is a key component, and its rust prevention treatment directly affects the engine's service life and reliability. Currently, rust prevention treatment of the engine cylinder head 5 is generally completed through spraying equipment, and mainly involves spraying a rust-proof coating onto the sides of the engine cylinder head 5, failing to provide rust prevention treatment for the mounting position of the engine cylinder head 5 where it connects to the valve cover 17. (Refer to...) Figure 6 As shown, a valve cover 17 is usually installed on the top of the engine cylinder head 5. A sealing ring 18 is also provided between the top of the engine cylinder head 5 and the valve cover 17 to improve the sealing between the top of the engine cylinder head 5 and the valve cover 17. This creates a gap between the engine cylinder head 5 and the valve cover 17. In addition, the top of the engine cylinder head 5 has an exposed cylinder head machining surface 19. Therefore, after the engine gets wet or exposed to rain, the top of the engine cylinder head 5 is prone to rust, which affects the engine's performance and service life.

[0030] To improve the rust prevention effect on the top of the engine cylinder head 5, this utility model provides an engine cylinder head rust prevention system, see [link to relevant documentation]. Figures 1-3 As shown, according to one embodiment of the rust prevention system of this utility model, the rust prevention system includes: a paint supply device having a paint dispensing component 2, a position sensing device 20 for detecting the position of the engine cylinder head 5, and a collaborative robot 1 connected to the paint dispensing component 2. The paint dispensing component 2 is used to deliver rust-preventive paint to the engine cylinder head 5, and the collaborative robot 1 is configured to control the paint dispensing component 2 to move along a predetermined trajectory on the end face where the engine cylinder head 5 and the valve cover 17 are mounted when the position sensing device 20 detects the position of the engine cylinder head 5.

[0031] Through the above technical solution, in the engine cylinder head anti-rust system of this utility model, when the position sensing device 20 detects the position of the engine cylinder head 5, the collaborative robot 1 starts working. The collaborative robot 1 can move along a predetermined trajectory on the end face where the engine cylinder head 5 and the valve cover 17 are installed. The collaborative robot 1 is connected to a paint dispensing component 2 of a paint supply device. The collaborative robot 1 moves along the predetermined trajectory, causing the paint dispensing component 2 to move along the predetermined trajectory at the same time. The paint dispensing component 2 can deliver anti-rust paint to the engine cylinder head 5, thereby spraying the anti-rust paint onto the end face where the engine cylinder head 5 and the valve cover 17 are installed, such as a predetermined position on the top of the engine cylinder head 5, through the movement of the paint dispensing component along the predetermined trajectory. An anti-rust paint coating is formed at the predetermined position, thus reducing the risk of rust formation on the top of the engine cylinder head 5 after the engine is exposed to rain or moisture. Moreover, through the coordinated operation of the position sensing device 20, the paint supply device, and the collaborative robot 1, the anti-rust work of the engine cylinder head 5 is automated, improving the efficiency of the anti-rust work of the engine cylinder head 5.

[0032] In some implementations, refer to Figure 2As shown, the rust prevention system of this utility model also includes a blocking device 3. The blocking device 3 is configured to prevent the engine cylinder head 5 from moving when the position sensing device 20 detects the position of the engine cylinder head 5. This makes it easier for the collaborative robot 1 and the paint dispensing component 2 to spray anti-rust paint onto the engine cylinder head 5.

[0033] In the engine manufacturing process, a conveying system, such as a conveying system composed of electric motors and rollers or a conveyor belt, is typically used to transport the engine cylinder head 5. To prevent the engine cylinder head 5 from continuing to move under the drive of the conveying system, the rust prevention system of this invention uses a blocking device 3. The location of the blocking device 3 in this invention is not specifically limited, as long as it can prevent the engine cylinder head 5 from moving and keep it within the working range of the collaborative robot 1. Of course, to facilitate the rust prevention operation of the collaborative robot 1 on the engine cylinder head 5, the blocking device 3 can be located downstream of the collaborative robot 1 and close to its position, along the direction of movement of the engine cylinder head.

[0034] In the rust prevention system of this utility model, the blocking device 3 can have a variety of different structures. For example, in one embodiment, the blocking device 3 includes a baffle that is pivotally connected to one side of the movement path of the engine cylinder head 5. When the baffle is rotated to be perpendicular to the movement direction of the engine cylinder head 5, the baffle is on the movement path of the engine cylinder head 5, thereby blocking the movement of the engine cylinder head 5. When the baffle is rotated to be parallel to the movement direction of the engine cylinder head 5, the baffle moves out of the movement path of the engine cylinder head 5, and the engine cylinder head 5 can continue to move.

[0035] Alternatively, according to one embodiment of the rust prevention system of this utility model, refer to Figure 2 and Figure 4 As shown, the blocking device 3 includes a support component 9 and a first lifting unit 10 disposed on the support component 9. The support component 9 can be a support plate and can be installed on a conveying system. The first lifting unit 10 can move up and down. When the first lifting unit 10 is in the raised state, it can prevent the engine cylinder head 5 from moving. When the first lifting unit 10 is lowered to the initial state, the engine cylinder head 5 can continue to move to the next work station through the conveying system.

[0036] In some embodiments, the first lifting unit 10 may include a first lifting cylinder, one end of which is provided with a blocking element, such as a baffle. The first lifting cylinder controls the baffle to rise, thereby blocking the engine cylinder head 5. Of course, the first lifting unit 10 may also use an electric motor and a lifting rod to control the raising and lowering of the blocking element.

[0037] In some implementations, refer to Figure 1As shown, the rust prevention system of this utility model also includes a positioning device 4, which includes a second lifting unit 14. The second lifting unit 14 is configured to control the engine cylinder head 5 to move up and down when the position sensing device 20 detects the position of the engine cylinder head 5, so that the engine cylinder head 5 is close to the paint outlet component 2, thereby facilitating the collaborative robot 1 to control the paint outlet component 2 to move along a predetermined trajectory on the top of the engine cylinder head 5, and complete the rust prevention operation on the predetermined position of the top of the engine cylinder head 5.

[0038] In the rust prevention system of this utility model, the second lifting unit 14 can be in the form of an electric motor and a lifting rod. The electric motor drives the lifting rod to raise or lower the engine cylinder head 5. Of course, the second lifting unit 14 can also include a second lifting cylinder, which controls the raising or lowering of the engine cylinder head 5.

[0039] In some implementations, refer to Figure 1 and Figure 5 As shown, the positioning device 4 also includes a support plate driven by the second lifting unit 14 and multiple support columns 12 disposed on the support plate. The support columns 12 are used to support the pallet of the engine cylinder head 5. To facilitate the transport of the engine cylinder head 5, a pallet is typically used. The side of the support plate away from the engine cylinder head 5 is driven by the second lifting unit 14. The second lifting unit 14 drives the support plate to move up and down. Multiple support columns 12 are disposed on the side of the support plate closest to the engine cylinder head 5, combined with... Figure 5 As shown, the support plate is equipped with four support columns 12, which are respectively located at the four corners of the support plate to support the pallet. Of course, the number of support columns 12 can also be other numbers, which can be adjusted according to the actual situation. Figure 5 As shown, the positioning device 4 also includes a guide shaft 11, one end of which is connected to the side of the support plate away from the engine cylinder head 5. The guide shaft 11 is movably connected to the support frame, which is used to connect to the conveying system. The guide shaft can improve the stability of the second lifting unit 14 driving the support plate to lift.

[0040] In some implementations, refer to Figure 5 As shown, the positioning device 4 also includes a positioning pin 13 disposed on the end of the support column 12. The positioning pin 13 is used to connect with the pin hole on the tray. The bottom of the tray may be provided with a pin hole that matches the positioning pin 13. When the tray containing the engine cylinder head 5 moves to the position of the positioning device 4, the positioning pin 13 connects with the pin hole, thereby ensuring the stability of the second lifting unit 14 driving the engine cylinder head 5 to perform lifting and lowering movements.

[0041] In some embodiments, the position sensing device 20 in the rust prevention system of this invention includes, but is not limited to, photoelectric position sensors, magnetoelectric position sensors, etc., as long as it can detect the position of the engine cylinder head 5. It should be noted that the position sensing device 20 can be positioned upstream of the collaborative robot 1 along the moving direction of the engine cylinder head 5. In this way, when the position sensing device 20 detects the position of the engine cylinder head 5, the first lifting unit 10 of the blocking device 3 can be raised to stop the engine cylinder head 5, the positioning device 4 lifts the pallet, and the collaborative robot 1 begins to work. Of course, depending on the actual production situation, the position sensing device 20 can also be positioned in other locations.

[0042] In some implementations, refer to Figure 3 As shown, the rust prevention system of this utility model also includes a vision recognition component installed on the collaborative robot 1. The vision recognition component can identify the model of the engine cylinder head 5. According to one embodiment of the rust prevention system of this utility model, the vision recognition component includes a camera 8. The engine cylinder head 5 is affixed with a label having a QR code recording the model of the engine cylinder head 5. By scanning the QR code of the engine cylinder head 5 with the camera 8, the type of the engine cylinder head 5 is identified and recorded. The collaborative robot 1 moves along a predetermined path corresponding to the type of engine cylinder head 5 to perform rust prevention work. After the work is completed, the positioning device 4 controls the engine cylinder head 5 to descend onto the conveying system, the first lifting unit 10 of the blocking device 3 descends, and the conveying system transports the engine cylinder head 5 to the next workstation for further work.

[0043] In some embodiments, the paint supply device further includes a paint storage unit for storing rust-preventive paint and communicating with the paint outlet component 2, and a controller for controlling the delivery of rust-preventive paint from the paint storage unit to the paint outlet component 2. A pump may be installed on the exhaust component 2, and the controller controls the operation of the pump, thereby controlling the flow rate of rust-preventive paint delivered from the paint storage unit to the paint outlet component 2 to achieve rust prevention of the engine cylinder head 5.

[0044] In some implementations, refer to Figure 3As shown, the outlet of the paint dispensing component 2 can be equipped with a brush 7. The collaborative robot 1 controls the brush 7 to move along a predetermined path on the top of the engine cylinder head 5, thereby applying anti-rust paint to a predetermined position on the top of the engine cylinder head 5, completing the anti-rust operation of the engine cylinder head 5. Of course, the outlet of the paint dispensing component 2 can also be in the form of a nozzle to spray the anti-rust paint onto the top of the engine cylinder head 5. As mentioned above, the top of the engine cylinder head 5 is generally installed with the valve cover 17 and the sealing ring 18. Therefore, the top of the engine cylinder head 5 needs to ensure a high degree of flatness and sealing. It usually needs to be precision machined before assembly to avoid uneven paint layer thickness that may result from spraying anti-rust paint, which would affect the sealing performance of the engine cylinder head 5. The rust prevention system of this utility model uses a collaborative robot 1 to control the paint dispensing component 2 to spray rust-preventive paint onto a predetermined position on the top of the engine cylinder head 5. On the one hand, the position where the top of the engine cylinder head 5 is installed with the sealing ring 18 or the valve cover 17 is not affected by the rust-preventive paint coating, ensuring high flatness and sealing performance. On the other hand, the area outside the position where the top of the engine cylinder head 5 is installed with the sealing ring 18 or the valve cover 17, such as the machined surface 19 of the cylinder head, is coated with rust-preventive paint, improving the rust prevention performance of the engine cylinder head 5.

[0045] In some embodiments, the rust-preventive paint may be a single-component rust-preventive paint, or, according to one embodiment of the rust-preventive system of this utility model, the rust-preventive paint includes a first component paint and a second component paint, see reference. Figure 2 and Figure 3 As shown, the paint storage unit includes a first paint storage component 15 for storing a first component paint and a second paint storage component 16 for storing a second component paint. The first paint storage component 15 and the second paint storage component 16 are respectively connected to the paint dispensing component 2. The paint dispensing component 2 is equipped with two pumps 6, which are respectively connected to the first paint storage component 15 and the second paint storage component 16. The controller can control the two pumps 6 to control the first paint storage component 15 and the second paint storage component 16 to deliver the first component paint and the second component paint to the paint dispensing component 2, so that the mixing ratio of the first component paint and the second component paint reaches a predetermined value. In one embodiment, the pump 6 can be a precision metering pump, the first component paint can be a varnish, and the second component paint can be a hardener. The controller controls the two precision metering pumps to achieve precise metering and quantitative output. The first component paint and the second component paint enter the paint dispensing component 2 through pipelines and are applied to the engine cylinder head 5 by the brush 7 to complete the rust prevention operation of the engine cylinder head 5.

[0046] This utility model also provides an engine production line, including a conveying system and the aforementioned engine cylinder head anti-rust system, wherein the conveying system is used to convey the engine cylinder head 5.

[0047] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
