[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above - mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order different from those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0042] In one embodiment, Figure 1 Schematic diagram of the structure of an anti - misassembly system for a diesel engine crankshaft bearing shell assembly provided by an embodiment of the present invention. This embodiment is applicable to improving the accuracy of the assembly between the bearing shell and the diesel engine and reducing the probability of misassembly, such as Figure 1 As shown, the system includes: a reading module 1 for reading the unique code of the diesel engine, where the unique code at least includes the model and the serial number; a host computer module 2 electrically connected to the reading module 1 for receiving the unique code and outputting the bearing shell part number uniquely corresponding to the unique code; a controller 3 electrically connected to the host computer module 2 for receiving the bearing shell part number and determining the picking window corresponding to the bearing shell part number to assemble the crankshaft bearing shell in the picking window onto the diesel engine.

[0043] Among them, usually, each diesel engine is pre-set with a corresponding unique code, and the diesel engine can be uniquely determined according to the unique code. The reading module 1 includes a reader and a unique code acquisition unit. The reader is a radio frequency identification reader and can be set on the transport roller path for transporting the diesel engine. The unique code acquisition unit is used to acquire the unique code of the diesel engine read by the reader. The unique code at least includes the model and serial number of the diesel engine. For example, the unique code acquired by the reading module 1 is a string of numbers, which includes the model, serial number and other information such as the production date. It is also possible that the acquired unique code only includes the model and serial number, and the serial number can uniquely specify a diesel engine. Therefore, after the reading module 1 reads the unique code of the diesel engine, the diesel engine can be uniquely determined. The host computer module 2 is used to receive the unique code of the diesel engine read by the reading module 1 and output the bearing shell part number uniquely corresponding to the unique code according to the unique code. Among them, the host computer module 2 can store the correspondence between the unique code of the diesel engine and the bearing shell part number. Therefore, after receiving the unique code, the host computer module 2 can output the bearing shell part number corresponding to the unique code from the stored correspondence. Alternatively, the host computer module 2 can obtain a relationship diagram in which the unique code and the bearing shell part number are in one-to-one correspondence, and at this time, the bearing shell part number can be output according to the obtained relationship diagram. Specifically, it can be determined according to the actual situation and is not limited here. The controller 3 is the core control unit of the bearing shell assembly error prevention system and is used to receive the bearing shell part number and determine the material taking window corresponding to the bearing shell part number.

[0044] Specifically, when the diesel engine stops on the transport roller path, the reading module 1 will read the unique code on the diesel engine and send the unique code to the host computer module 2. After receiving the unique code, the host computer module 2 will output the bearing shell part number uniquely corresponding to the unique code and send the bearing shell part number to the controller 3. After receiving the bearing shell part number, the controller 3 will determine the material taking window corresponding to the bearing shell part number, so as to assemble the crankshaft bearing shell in the determined material taking window onto the diesel engine. Usually, there are multiple material taking windows, and the crankshaft bearing shells in each material taking window are different. The crankshaft bearing shells in one material taking window are the same, and the crankshaft bearing shells are usually set in a partitioned or boxed manner, that is, there is a bearing shell part number on a box of crankshaft bearing shells, and the material taking window is uniquely corresponding to the bearing shell part number. Therefore, after receiving the bearing shell part number, the controller 3 has already determined the material taking window where the crankshaft bearing shell corresponding to the bearing shell part number is located, thus completing the assembly of the crankshaft bearing shell of the diesel engine. Exemplarily, there are 8 material taking windows, and each box of crankshaft bearing shells includes 7, that is, a diesel engine is assembled with 7 crankshaft bearing shells.

[0045] The technical solution of the embodiment of the present invention is to set a reading module, a host computer module and a controller, and electrically connect the host computer module to the reading module and the controller respectively. After the transportation of the diesel engine stops, the reading module will read the unique code on the diesel engine and send the unique code to the host computer module. After receiving the unique code, the host computer module will output the bearing part number that uniquely corresponds to the unique code, and send the bearing part number to the controller. After receiving the bearing part number, the controller will determine the material collection window corresponding to the bearing part number, so as to assemble the crankshaft bearing in the determined material collection window to the diesel engine. With the above structure, the material collection window corresponding to the unique code of the diesel engine is determined by the controller, and the crankshaft bearing in the material collection window is assembled to the diesel engine, which improves the accuracy of assembly, reduces the cost, and reduces the assembly error rate.

[0046] It should be noted that the system also includes a power module, which is usually a three-phase 380V AC voltage, which is converted into 220V AC and 24V DC after filtering and transformer to power the controller 3, reading module 1 and host computer module 2.

[0047] In another specific embodiment, optionally, Figure 2 The schematic diagram of the structure of the second diesel engine crankshaft bearing assembly error prevention system provided by the embodiment of the present invention is shown in FIG. Figure 2 As shown, the system also includes multiple window indicator light display units 5; the multiple window indicator light display units 5 are located at the front end of each material collection window 4, and the number is the same as the material collection window 4; the controller 3 is electrically connected to each window indicator light display unit 5, and is used to control the window indicator light display unit 5 in front of the material collection window 4 corresponding to the bearing part number to light up.

[0048] The window indicator light display unit 5 is used to light up or turn off under the control of the controller 3. The window indicator light display unit 5 is located at the front end of the material taking window 4, and each material taking window 4 is provided with a window indicator light display unit 5. Figure 2 Only one material collection window 4 is shown as an example. In this embodiment, the controller 3 is electrically connected to each window indicator light display unit 5. After the controller 3 determines the material collection window 4 corresponding to the bearing part number, the window indicator light display unit 5 at the front end of the material collection window 4 will be controlled to light up, while the window indicator light display units 5 at the front end of other material collection windows 4 are in an off state, so as to prompt the staff to take the crankshaft bearing from the lit material collection window 4 to assemble it to the diesel engine, saving time and improving the staff's experience. Among them, the color of the illuminated window indicator light display unit 5 can be determined according to actual needs, and can be a monochrome light or a multi-color light, which is not limited here. For example, the window indicator light display unit 5 is displayed as a green light when it is lit.

[0049] In another specific embodiment, optionally, continue to refer to Figure 2 , the system further includes a plurality of anti-error gratings 6 and an alarm module 7; the plurality of anti-error gratings 6 are located at the front ends of the respective material taking windows 4; the controller 3 is electrically connected to the alarm module 7 and each anti-error grating 6 respectively, and is configured to receive an assembly error signal returned by the anti-error grating 6 when the crankshaft bearing bush and the diesel engine are assembled incorrectly, and control the alarm module 7 to give an alarm when receiving the assembly error signal.

[0050] Among them, the anti-error grating 6 is a structure that realizes the anti-error function by using grating detection technology. The anti-error grating 6 includes a transmitter and a receiver. The transmitter emits infrared light or visible light beams, and the receiver receives the beam signals. When an object (such as a workpiece, a tool or a hand) enters the detection area of the grating, the light beam will be blocked, and the grating will output a signal to the controller 3. In this embodiment, the anti-error grating 6 is arranged at the front end of the material taking window 4, and one or two anti-error gratings 6 can be arranged at the front end of one material taking window 4 according to needs. The alarm module 7 is configured to give an alarm under the control of the controller 3. The alarm sound can include but is not limited to "beep beep beep" or "click click click", etc. The alarm module 7 can include a buzzer, etc.

[0051] Specifically, when determining the accuracy of the assembly of the diesel engine and the crankshaft bearing bush, by electrically connecting the controller 3 to the alarm module 7 and each anti-error grating 6 respectively, after the controller 3 determines the material taking window 4, it will control the lighting of the material taking window 4 to prompt the staff to take the crankshaft bearing bush in the material taking window 4 and assemble it to the diesel engine. At this time, during the assembly process by the staff, the anti-error grating 6 at the front end of the material taking window 4 will detect that the light beam is blocked and generate an electrical signal to the controller 3. After receiving the electrical signal, the controller 3 determines that the material taking window 4 taken by the staff is correct and the assembly is successful. In addition, at this time, the anti-error gratings 6 at the front ends of the other material taking windows 4 will not generate electrical signals because there is no need to take the crankshaft bearing bush. When the controller 3 receives the electrical signals generated by the anti-error gratings 6 at the front ends of the other material taking windows 4, it indicates that the staff has taken the crankshaft bearing bush in the material taking window 4 to assemble the diesel engine. At this time, the controller 3 will determine that the staff has assembled incorrectly, and the electrical signal generated by the anti-error grating 6 is an assembly error signal. Therefore, after receiving the assembly error signal, the controller 3 will control the alarm module 7 to give an alarm to prompt the staff of the assembly error, avoid the assembly error, and improve the assembly accuracy.

[0052] In another specific embodiment, optionally, continue to refer to Figure 2 , the system further includes a display module 8; the display module 8 is electrically connected to the controller 3, and the controller 3 is configured to control the display module 8 to display the reason for the assembly error after receiving the assembly error signal.

[0053] Among them, the display module 8 is used to display the reasons for assembly errors. The display module 8 may include, but is not limited to, a "display screen", "liquid crystal screen", etc. that can be used for display. In this embodiment, after receiving the assembly error signal, the controller 3 controls the display module 8 to display the reasons for assembly errors, such as information like "error in taking the picking window", etc., which facilitates the staff to quickly understand the reasons for the errors and improves the assembly efficiency. Additionally, the display module 8 may also be integrated into the host computer module 2. In this case, the controller 3 controls the host computer module 2 so that the host computer module 2 controls the display module 8 to display the assembly error information, and no limitation is made here.

[0054] In another specific embodiment, optionally, continue to refer to Figure 2 , the system further includes a fault lamp display unit 9; the fault lamp display unit 9 is electrically connected to the controller 3, and the controller 3 is used to control the fault lamp display unit 9 to light up after receiving the assembly error signal.

[0055] Among them, the fault lamp display unit 9 is used to indicate the occurrence of fault information. The fault lamp display unit 9 may include, but is not limited to, a three-color lamp, etc. In this embodiment, after receiving the assembly error signal, the controller 3 controls the fault lamp display unit 9 to light up to prompt the staff of the assembly error and improve the assembly accuracy.

[0056] In another specific embodiment, optionally, continue to refer to Figure 2 , the system further includes a storage module 12; the storage module 12 stores the correspondence between the diesel engine unique code and the bearing shell part number; the host computer module 2 is communicatively connected to the storage module 12 and is used to obtain the bearing shell part number corresponding to the unique code stored in the storage module 12 and output it.

[0057] Among them, the storage module 12 is used to store the unique correspondence between the diesel engine unique code and the bearing shell part number. The storage module 12 may include, but is not limited to, a CAPP server, etc. In this embodiment, after receiving the unique code, the host computer module 2 will simultaneously obtain the corresponding relationship stored in the storage module 12, determine the bearing shell part number uniquely corresponding to the received unique code, and output the bearing shell part number to the controller 3, so that the host computer module 2 can quickly and accurately output the corresponding bearing shell part number and improve the assembly speed.

[0058] In another specific embodiment, optionally, Figure 3 is a schematic structural diagram of a transportation roller provided by an embodiment of the present invention. Refer to Figure 2 and Figure 3As shown, the system further includes a line track control module 10; the line track control module 10 is electrically connected to the transport roller path 11 of the diesel engine and the controller 3 respectively, and is used to control the start and stop of the transport roller path 11; the controller 3 is further used to send an assembly completion signal to the line track control module 10 after the crankshaft bearing shell is assembled with the diesel engine, so that the line track control module 10 controls the transport roller path 11 to start.

[0059] Among them, the line track control module 10 is used to control the start and stop of the transport roller path 11 for transporting the diesel engine. The line track control module 10 can be a line track PLC.

[0060] Specifically, when the diesel engine is being transported on the transport roller path 11, when it reaches a preset position, the line track control module 10 will control the transport roller path 11 to stop. At this time, the reading module 1 will read the unique code of the diesel engine. After the diesel engine and the crankshaft bearing shell are assembled, it is necessary to transport the diesel engine to the next process for the assembly of the next diesel engine. At this time, the controller 3 will send an assembly completion signal to the line track control module 10. After receiving this assembly completion signal, the line track control module 10 will control the transport roller path 11 to start to transport the diesel engine for the assembly of the next diesel engine. The assembly process of the next diesel engine is the same as that of this diesel engine and will not be elaborated here.

[0061] In another specific embodiment, optionally, continue to refer to Figure 2 and Figure 3 , the system further includes a proximity switch 15; the proximity switch 15 is located on the transport roller path 11, and the proximity switch 15 is electrically connected to the line track control module 10; the line track control module 10 is used to control the proximity switch 15 to close after receiving the assembly completion signal, so that the transport roller path 11 starts.

[0062] Among them, the proximity switch 15 is a sensor that can detect the position of an object without direct contact with the target object. The proximity switch has two basic states: on and off (or open and closed). When no diesel engine is detected, the proximity switch 15 is in one state (such as closed), and when an object is detected, it switches to another state (such as open). This change in state is used as a trigger signal.

[0063] Specifically, when the diesel engine is transported to a preset position on the transport roller path 11, the proximity switch 15 will detect the diesel engine. At this time, the proximity switch 15 is in an open state. After the signal of this open state is sent to the line track control module 10, the line track control module 10 will control the transport roller path 11 to stop in order to read the unique code of the subsequent diesel engine. After the line track control module 10 receives the assembly completion signal sent by the controller 3, indicating that the assembly of this diesel engine is completed and the assembly of the next diesel engine needs to be carried out, the line track control module 10 will control the proximity switch 15 to close, so that the transport roller path 11 is opened. When the line track control module 10 receives the assembly error signal, it will control the proximity switch 15 to always remain in the open state, so that the transport roller path 11 stops transporting. At this time, manual intervention is required for reassembly until the assembly is completed directly.

[0064] In another specific embodiment, optionally, Figure 4 is a schematic structural diagram of a lifting mechanism provided by an embodiment of the present invention. Refer to Figure 2 and Figure 4 As shown, the system further includes a lifting mechanism 13; the material taking window 4 is fixed to the upper end of the lifting mechanism 13; a lifting solenoid valve 14 (not shown in the figure) is provided on the lifting mechanism 13, and the lifting solenoid valve 14 is electrically connected to the controller 3; the controller 3 is used to obtain a lifting adjustment signal generated when the user presses the start button of the lifting mechanism 13, and control the lifting solenoid valve 14 to perform position switching according to the lifting adjustment signal, so as to control the lifting mechanism 13 to rise or fall.

[0065] Among them, the lifting mechanism 13 is a structure for rising or falling. The lifting solenoid valve 14 is a device that controls the flow direction or on / off of a fluid (such as hydraulic oil or compressed air) through electromagnetic force. In the elevator system, the lifting solenoid valve 14 is usually used to control the action of a hydraulic cylinder or a pneumatic cylinder, so as to realize the rising or falling of the lifting mechanism 13.

[0066] Specifically, the material taking window 4 is fixed to the upper end of the lifting mechanism 13. When the staff takes the crankshaft bearing shell in the material taking window 4, if the material taking window 4 is too high or too low, the staff can adjust the lifting mechanism 13. There is a start button on the lifting mechanism 13. The start button can include a rising start button and a falling start button. The lifting adjustment signal can include a rising adjustment signal and a falling adjustment signal. If the height of the lifting mechanism 13 is relatively low and the staff wants to raise the lifting mechanism 13, the rising start button can be pressed. When the user presses the rising start button, a rising adjustment signal will be generated. The controller 3 will obtain this rising adjustment signal and control the lifting solenoid valve 14 to switch to a specific position. This position allows the fluid to flow into the bottom of the hydraulic cylinder (assuming bottom drive), pushing the piston rod upward, so that the lifting mechanism 13 rises. If the height of the lifting mechanism 13 is relatively high and the staff wants to lower the lifting mechanism 13, the falling start button can be pressed. When the user presses the falling start button, a falling adjustment signal will be generated. The controller 3 will obtain this falling adjustment signal and control the lifting solenoid valve 14 to switch to another position. This position will allow the fluid to flow into the top of the hydraulic cylinder and be discharged from the bottom, causing the piston rod to move downward, realizing the lowering of the lifting mechanism 13. It should be noted that the rising or falling height of the lifting mechanism 13 is determined according to the time of the lifting adjustment signal. When the staff continuously presses the start button, the lifting mechanism 13 will be continuously controlled to rise or fall until the user stops pressing the start button, and then the lifting mechanism 13 will be controlled to stop adjusting. At this time, it indicates that the staff's adjustment is in place and there is no need to bend down for work, improving the experience.

[0067] Based on the same inventive concept, the present invention provides a control method for an anti-misassembly system of a diesel engine crankshaft bearing shell, which is applied to the above anti-misassembly system of a diesel engine crankshaft bearing shell, and the method is executed by a controller; Figure 5 It is a flowchart of a control method for an anti-misassembly system of a diesel engine crankshaft bearing shell provided by an embodiment of the present invention. Refer to Figure 5 As shown, the method includes:

[0068] S110. Receive the bearing shell part number sent by the upper computer module.

[0069] S120. Determine the material taking window corresponding to the bearing shell part number according to the bearing shell part number, and assemble the crankshaft bearing shell in the material taking window to the diesel engine.

[0070] Specifically, after receiving the bearing shell part number sent by the host computer module, the picking window corresponding to the bearing shell part number will be determined, so as to assemble the crankshaft bearing shells in the determined picking window onto the diesel engine. Usually, there are multiple picking windows, and the crankshaft bearing shells in each picking window are different. The crankshaft bearing shells in one picking window are the same, and the crankshaft bearing shells are usually arranged in a partitioned or boxed manner, that is, there will be a bearing shell part number on a box of crankshaft bearing shells, and the picking window corresponds uniquely to the bearing shell part number. Therefore, after receiving the bearing shell part number, the picking window where the crankshaft bearing shell corresponding to the bearing shell part number is located has been determined, thus completing the assembly of the crankshaft bearing shells of the diesel engine. Exemplarily, there are 8 picking windows, and each box of crankshaft bearing shells includes 7, that is, 7 crankshaft bearing shells are assembled for one diesel engine.

[0071] The technical solution of the embodiment of the present invention is to receive the bearing shell part number sent by the host computer module; according to the bearing shell part number, determine the picking window corresponding to the bearing shell part number to assemble the crankshaft bearing shells in the picking window onto the diesel engine. By using the above method, by determining the picking window corresponding to the unique code of the diesel engine and assembling the crankshaft bearing shells in the picking window onto the diesel engine, the assembly accuracy is improved, the cost is low, and the assembly error rate is reduced.

[0072] It should be understood that the various forms of the processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in the present invention can be executed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved, and no limitation is made herein.

[0073] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
