[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0036] like Figure 1-2As shown, this embodiment provides a cylinder head assembly line, including a conveying flow line 1, a first flow line adjustment mechanism 21, and a pallet transfer mechanism 3. The conveying flow line 1 includes multiple branch lines 13, each including two conveying branch lines 13a and a connecting branch line 13b. The conveying directions of the connecting branch line 13b and the conveying branch line 13a are both parallel to a first direction. The two conveying branch lines 13a are respectively located at both ends of the connecting branch line 13b along the first direction, and the two conveying branch lines 13a are parallel to a second direction. With a directional misalignment setting, the first streamline adjustment mechanism 21 can adjust the position of the connecting branch line 13b along the second direction so that the connecting branch line 13b can selectively connect to one of the two conveying branch lines 13a; the second direction is perpendicular to the first direction; the branch line 13 includes an upper conveying module 131 and a lower conveying module 132, with the lower conveying module 132 located below the upper conveying module 131; the pallet transfer mechanism 3 can transfer the cylinder head pallet 100 between the upper conveying module 131 and the lower conveying module 132.

[0037] In this embodiment, the cylinder head assembly line has two conveying branch lines 13a staggered along the second direction, and the first flow line adjustment mechanism 21 can adjust the position of the connecting branch line 13b along the second direction so that the connecting branch line 13b can selectively connect to one of the two conveying branch lines 13a. This allows the cylinder head tray 100 to be conveyed between the two conveying branch lines 13a. This not only facilitates the avoidance of other equipment in the workshop by the conveying flow line 1, thus facilitating the workshop layout, but also improves the smoothness of the cylinder head tray 100's conveying on the conveying flow line 1.

[0038] Furthermore, the conveyor line 1 includes a loading end 11 and a unloading end 12. Both the upper conveyor module 131 and the lower conveyor module 132 can convey the cylinder head tray 100. At the loading end 11, the cylinder head body 200 is placed on the cylinder head tray 100 on the upper conveyor module 131, and the cylinder head body 200 can be conveyed by the upper conveyor module 131. When the cylinder head body 200 flows to the unloading end 12, the cylinder head body 200 is removed, and then the empty cylinder head tray 100 is transported to the lower conveyor module 132 by the tray transfer mechanism 3, so that the cylinder head tray 100 can flow back to the loading end 11 through the lower conveyor module 132. The tray transfer mechanism 3 then transports the cylinder head tray 100 from the lower conveyor module 132 to the upper conveyor module 131, thereby enabling the cylinder head tray 100 to be recycled, which helps to reduce the space occupied by the conveyor line 1 and improves assembly efficiency.

[0039] For example, the pallet transfer mechanism 3 includes two lifting modules 31, which are respectively located at both ends of the conveying flow line 1 along its conveying direction. When the cylinder head pallet 100 flows from the upper conveying module 131 to the unloading end 12, the lifting module 31 located at the unloading end 12 lowers the cylinder head pallet 100 and transports it to the lower conveying module 132. When the cylinder head pallet 100 flows from the lower conveying module 132 to the loading end 11, the lifting module 31 located at the loading end 11 rises the cylinder head pallet 100 and transports it to the upper conveying module 131.

[0040] Furthermore, the lifting module 31 includes a lifting platform and a lifting drive assembly. The drive end of the lifting drive assembly is connected to the lifting platform, thereby driving the lifting platform to rise and fall. The upper conveying module 131 and the lower conveying module 132 can push the cylinder head tray 100 onto the lifting platform, and then the lifting drive assembly drives the lifting platform to rise and fall. Further, the lifting platform is provided with a tray clamp, a clamp drive assembly, and a push drive assembly. The clamp drive assembly can drive the tray clamp to open and close, so that the tray clamp can hold the cylinder head tray 100. The push drive assembly can drive the tray clamp to move, so as to push the cylinder head tray 100 onto the upper conveying module 131 or the lower conveying module 132. Exemplarily, the clamp drive assembly is a cylinder; the push drive assembly is a cylinder; and the lifting drive assembly is a cylinder. Of course, the lifting module 31 can also adopt other structures in the prior art, and the structure of the tray clamp can be any existing clamp capable of opening and closing; no limitation is made here.

[0041] It should be noted that the upper conveying module 131 and the lower conveying module 132 can use conveying structures such as rollers or conveyor chains to convey the cylinder head pallet 100. Of course, other conveying structures in the prior art can also be used to convey the cylinder head pallet 100, and this is not limited here. Furthermore, the structure of the pallet clamp and...

[0042] In one embodiment, different conveying branches 13a have different lengths along the first direction, which helps to improve the flexibility of the conveying branches 1 in the workshop layout.

[0043] In one embodiment, the cylinder head assembly line further includes a loading mechanism, which comprises a first loading module 41 and a second loading module 42. Both the first loading module 41 and the second loading module 42 can place the cylinder head body 200 onto the cylinder head tray 100 on the upper conveying module 131, thereby making the first loading module 41 and the second loading module 42 redundant. If one of the first loading module 41 and the second loading module 42 fails, the other can still be used for loading operations, improving the reliability of the cylinder head assembly line and reducing the downtime risk of the cylinder head assembly line. Exemplarily, the loading mechanism is located at the loading end 11.

[0044] In one embodiment, the cylinder head assembly line further includes a feeding mechanism, which comprises a first feeding module 43 and a second feeding module 44. Both the first feeding module 43 and the second feeding module 44 are capable of feeding the cylinder head body 200 conveyed by the upper conveying module 131, thus making the first feeding module 43 and the second feeding module 44 redundant. If one of the first feeding module 43 and the second feeding module 44 fails, the other can still be used for feeding, improving the reliability of the cylinder head assembly line and reducing the downtime risk. Exemplarily, the feeding mechanism is located at the feeding end 12.

[0045] In one embodiment, along the second direction, the second feeding module 42 is disposed on one side of the conveying branch line 13a located at the feeding end 11 of the conveying flow line 1; the plurality of branch lines 13 also include a feeding branch line 13c, the conveying direction of the feeding branch line 13c being parallel to the first direction; along the second direction, the first feeding module 41 is disposed on the side of the feeding branch line 13c away from the conveying flow line 1; the cylinder head sub-assembly line also includes a second flow line adjustment mechanism 22, which can adjust the position of the feeding branch line 13c along the second direction so that the feeding branch line 13c is connected to the conveying branch line 13a located at the feeding end 11, or so that the feeding branch line 13c is located on one side of the first feeding module 41. The cylinder head body 200 is fed to the feeding branch line 13c by the first feeding module 41, and then the position of the feeding branch line 13c along the second direction is adjusted by the second flow line adjustment mechanism 22 so that the feeding branch line 13c is connected to the conveying branch line 13a located at the feeding end 11. This allows the cylinder head body 200 to be conveyed from the feeding branch line 13c to the conveying branch line 13a. This makes the installation position of the first feeding module 41 more flexible. In other words, the installation position of the first feeding module 41 does not have to be adjacent to the conveying branch line 13a, which makes it easier to lay out the cylinder head assembly line in the workshop.

[0046] For example, the first streamline adjustment mechanism 21 includes a first slide table, a first slide rail, and a first adjustment drive assembly. The connecting branch line 13b is fixed to the first slide table, and the first slide table is slidably disposed on the first slide rail along a second direction. The drive end of the first adjustment drive assembly is connected to the first slide table, thereby driving the first slide table to move along the first slide rail in the second direction, thereby adjusting the position of the connecting branch line 13b along the second direction. The structure of the second streamline adjustment mechanism 22 can be referred to that of the first streamline adjustment mechanism 21, and will not be described again here.

[0047] In this embodiment, the conveyor flow line 1 includes two conveyor branch lines 13a, referred to as the first conveyor branch line and the second conveyor branch line, respectively; one connecting branch line 13b; and one loading branch line 13c. By adjusting the position of the loading branch line 13c along the second direction using the second flow line adjustment mechanism 22, one end of the loading branch line 13c can be connected to one end of the first conveyor branch line, thereby allowing the cylinder head tray 100 to flow between the loading branch line 13c and the first conveyor branch line. By adjusting the position of the connecting branch line 13b along the second direction using the first flow line adjustment mechanism 21, one end of the connecting branch line 13b can be connected to the other end of the first conveyor branch line, thereby allowing the cylinder head tray 100 to flow between the first conveyor branch line and the connecting branch line 13b. By adjusting the position of the connecting branch line 13b along the second direction through the first streamline adjustment mechanism 21, the other end of the connecting branch line 13b can be connected to the second conveying branch line, thereby enabling the cylinder head tray 100 to flow between the connecting branch line 13b and the second conveying branch line.

[0048] In one embodiment, the cylinder head assembly line further includes an automated guided vehicle (AGV) 5, which transports the cylinder head bodies 200 unloaded by the first unloading module 43 and the second unloading module 44 to the downstream workstation. It should be noted that the AGV 5 is an AGV. Transporting the cylinder head bodies 200 unloaded by the first unloading module 43 and the second unloading module 44 to the downstream workstation via the AGV 5 not only improves the working efficiency of the cylinder head assembly line but also allows for more precise transport of the cylinder head bodies 200 to the downstream workstation, thus improving the machining accuracy of the cylinder head bodies 200.

[0049] In one embodiment, the cylinder head assembly line further includes a valve stem assembly mechanism 61, a valve assembly mechanism 62, a valve lock clamp assembly mechanism 63, a valve tapping mechanism 64, an injector assembly mechanism 65, and a spark plug assembly mechanism 66, which are sequentially arranged along one side of the conveyor flow line 1 in a first direction. This enables automated assembly of the cylinder head body 200, thereby improving production efficiency. Specifically, the valve stem assembly mechanism 61, the valve assembly mechanism 62, the valve lock clamp assembly mechanism 63, the valve tapping mechanism 64, the injector assembly mechanism 65, and the spark plug assembly mechanism 66 are arranged sequentially from the loading end 11 to the loading end 12.

[0050] It should be noted that the cylinder head assembly line is equipped with both an injector assembly mechanism 65 and a spark plug assembly mechanism 66. This allows the cylinder head assembly line to assemble both the cylinder head body 200 of a fuel engine and the cylinder head body 200 of a gas engine. This is equivalent to integrating the cylinder head assembly line for fuel engines and the cylinder head assembly line for gas engines, improving the versatility of the cylinder head assembly line and greatly reducing the space occupied by the cylinder head assembly line in the workshop.

[0051] In one embodiment, the valve oil seal assembly mechanism 61, the valve assembly mechanism 62, the valve lock clamp assembly mechanism 63, the valve tapping mechanism 64, the fuel injector assembly mechanism 65, and the spark plug assembly mechanism 66 are respectively disposed on one side of at least two delivery branches 13a. In other words, the valve stem assembly mechanism 61, valve assembly mechanism 62, valve lock clamp assembly mechanism 63, valve tapping mechanism 64, injector assembly mechanism 65, and spark plug assembly mechanism 66 are all located on one side of the conveying branch line 13a. At least two of the valve stem assembly mechanism 61, valve assembly mechanism 62, valve lock clamp assembly mechanism 63, valve tapping mechanism 64, injector assembly mechanism 65, and spark plug assembly mechanism 66 are located on different sides of the conveying branch line 13a. However, no of the aforementioned assembly mechanisms or valve tapping mechanisms 64 are provided on the side of the connecting branch line 13b. This allows the connecting branch line 13b to only serve a steering function, resulting in a shorter length of the connecting branch line 13b along its conveying direction. This helps to reduce the space occupied by the conveying flow line 1 in the conveying direction of the connecting branch line 13b and facilitates the overall layout of the conveying flow line 1.

[0052] In one embodiment, the cylinder head assembly line also includes a valve sinking detection mechanism 71 located downstream of the valve assembly mechanism 62, so that after the valve assembly mechanism 62 assembles the valve to the cylinder head body 200, the valve sinking detection mechanism 71 can detect the valve sinking online, which is beneficial to realize the automated production of the cylinder head body 200.

[0053] In one embodiment, the cylinder head assembly line also includes a valve lock detection mechanism 72 located downstream of the valve lock assembly mechanism 63. After the valve lock assembly mechanism 63 assembles the spring, upper seat and valve lock to the cylinder head body 200, the valve lock detection mechanism 72 can detect online whether the valve lock is properly assembled, which is beneficial to realize the automated production of the cylinder head body 200.

[0054] In one embodiment, the cylinder head assembly line also includes a cylinder head valve leakage detection mechanism 73 located downstream of the valve tapping mechanism 64. After the valve tapping mechanism 64 causes the cylinder head body 200 to perform valve tapping operation, the cylinder head valve leakage detection mechanism 73 detects whether the valve leakage rate is qualified, thereby realizing online detection of valve leakage rate, which is beneficial to realizing automated production of cylinder head body 200.

[0055] In one embodiment, the cylinder head assembly line also includes an injector extension detection mechanism 74 located downstream of the injector assembly mechanism 65. After the injector assembly mechanism 65 assembles the injector to the cylinder head body 200 of the fuel engine, the injector extension detection mechanism 74 performs online detection of the injector extension, which is beneficial to realize the automated production of the cylinder head body 200.

[0056] In one embodiment, the cylinder head assembly line also includes a spark plug gap detection mechanism 75 located downstream of the spark plug assembly mechanism 66, so that after the spark plug assembly mechanism 66 assembles the spark plugs to the cylinder head body 200 of the gas engine, the spark plug gap detection mechanism 75 can perform online detection of the spark plug gap, which is beneficial to realize the automated production of the cylinder head body 200.

[0057] In one embodiment, the cylinder head assembly line also includes a repair mechanism 8, which can repair the cylinder head body 200 and the components assembled to the cylinder head body 200. When the valve sinking detection mechanism 71 detects that the valve sinking is unqualified, or the valve lock clamp detection mechanism 72 detects that the valve lock clamp assembly is unqualified, or the cylinder head valve leakage detection mechanism 73 detects that the valve leakage rate is unqualified, or the injector extension detection mechanism 74 detects that the injector extension is unqualified, or the spark plug gap detection mechanism 75 detects that the spark plug gap is unqualified, the upper conveying module 131 transports the cylinder head body 200 to the repair mechanism 8 for repair, which is conducive to realizing the automated production of the cylinder head body 200 and improving production efficiency.

[0058] Furthermore, when the cylinder head assembly line includes at least two of the following detection mechanisms: valve sinking detection mechanism 71, valve lock detection mechanism 72, cylinder head valve leakage detection mechanism 73, injector extension detection mechanism 74, and spark plug gap detection mechanism 75, the at least two detection mechanisms are located on both sides of the rework mechanism 8 along the conveying direction of the conveying flow line 1. This helps to shorten the distance between each detection mechanism and the rework mechanism 8. When the cylinder head body 200 or the parts assembled to the cylinder head body 200 need to be repaired, the cylinder head body 200 can be quickly conveyed to the rework mechanism 8 by moving the upper conveying module 131 forward or backward, which helps to improve production efficiency.

[0059] Specifically, the upper conveying module 131 moves forward, meaning that the upper conveying module 131 can convey the cylinder head body 200 from the loading end 11 to the loading end 12, and the upper conveying module 131 moves backward, meaning that the upper conveying module 131 can convey the cylinder head body 200 from the unloading end 12 to the loading end 11.

[0060] It should be noted that the first feeding module 41 and the second feeding module 42 both use feeding equipment in the prior art; the first unloading module 43 and the second unloading module 44 both use unloading equipment in the prior art; the valve oil seal assembly mechanism 61, the valve assembly mechanism 62, the valve lock clamp assembly mechanism 63, the valve tapping mechanism 64, the injector assembly mechanism 65 and the spark plug assembly mechanism 66 all use equipment in the prior art; the valve sinking detection mechanism 71, the valve lock clamp detection mechanism 72, the cylinder head valve leakage detection mechanism 73, the injector extension detection mechanism 74 and the spark plug gap detection mechanism 75 all use detection equipment in the prior art. This embodiment utilizes a double-layer design for the conveyor line 1 to maximize the use of vertical space in the workshop and reduce the floor space occupied. The rational layout of the branch lines 13 allows the cylinder head assembly line to be suitable for compact installation spaces. By arranging the assembly and testing mechanisms in conjunction with the conveyor line 1, both cylinder head bodies 200 for fuel engines and cylinder head bodies 200 for gas engines can be produced simultaneously, improving the versatility of the cylinder head assembly line and reducing the space occupied by the cylinder head assembly line in the workshop.

[0061] Furthermore, by having each assembly and testing organization identify the model markings on the cylinder head body 200 through visual inspection and other model inspection mechanisms, the cylinder head body 200 of the fuel engine and the cylinder head body 200 of the gas engine can be distinguished. This is existing technology in the field and will not be described in detail here.

[0062] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
