Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of transportation equipment, and particularly relates to a front end module transportation device. BACKGROUND

[0002] The front end module of an automobile is located at the front end of the automobile, and is an assembly composed of multiple front end components assembled together in advance. The front end module has a high degree of integration and is a core component of automobile modularization. After the front end module is assembled offline, the assembled front end module is transported to a detection device for detection. At present, the actual operation is generally to use a common transport vehicle for transportation. Since the shape of the front end module of the automobile is irregular, the positions of the installed components are prone to change during transportation. The front end module of the automobile integrates components such as pipes, cooling air conditioning systems, anti-collision beams, buffer blocks, headlamps, bumpers, air inlet grilles, and even fenders. In addition, other components on the whole vehicle, such as headlamps, front bumpers, hoods, and fenders, are related to the front end module. Therefore, the installation position precision of the components in the front end module is very important. Further, the positions of the components change during transportation, which not only fails to pass the detection, but also needs to be adjusted again. Moreover, it is not possible to determine whether the position change of the components is caused by assembly or transportation, which is not conducive to finding problems during assembly. SUMMARY

[0003] The present application is made to solve the above problems, and aims to provide a front end module transportation device for transporting an assembled front end module to a detection device. After the front end module is transported to the detection device, the front end module still maintains the state when it is assembled, and each component in the front end module is in a predetermined position.

[0004] The present application provides a front end module transportation device for transporting an assembled front end module to a detection device. The bottom of the front end module has multiple protrusions, and the detection device has a lifting mechanism. The device has the following characteristics: a transport vehicle for transporting the front end module; and a feeding table arranged at a position corresponding to the lifting mechanism. The transport vehicle includes a fixed support mechanism, a sliding strip, a detection metal piece, and a blocking block arranged on the fixed support mechanism. The fixed support mechanism is used to fixedly support the front end module, so that the front end module maintains a predetermined state. The feeding table includes a feeding plate, a transport belt, a sensor, and a blocking cylinder arranged on the feeding plate. The transport belt is matched with the sliding strip and is used to drive the transport vehicle to move. The sensor is arranged at a predetermined position of the feeding plate and is used to detect whether the detection metal piece moves to the predetermined position. When the detection metal piece moves to the predetermined position, the blocking cylinder cooperates with the blocking block to position the transport vehicle.

[0005] In the front end module transportation device provided by the application, the fixing support mechanism comprises a frame, a plate arranged on the top of the frame, and a fixing support assembly arranged on the plate, the fixing support assembly has a plurality of grooves matched with the positions and shapes of the protrusions in a clamping manner, and the grooves and the protrusions stably support the front end module so that the front end module is kept in a predetermined state.

[0006] In the front end module transportation device provided by the application, the slide and the metal detection piece are arranged on the bottom of the frame, and the blocking block is arranged on the front side of the frame.

[0007] In the front end module transportation device provided by the application, a plurality of proximity sensors are arranged on the plate for detecting the metal parts on the front end module.

[0008] In the front end module transportation device provided by the application, an aviation plug is further arranged on the plate.

[0009] In the front end module transportation device provided by the application, universal wheels are arranged on the bottom of the plate.

[0010] In the front end module transportation device provided by the application, the feeding plate comprises a feeding area, a first detection station, a second detection station and a detection area connected in sequence, and the first detection station and the second detection station are respectively provided with a sensor and a blocking cylinder.

[0011] Effects of the application

[0012] The application provides a front end module transportation device for transporting a completed front end module to a detection equipment, which comprises a transportation vehicle and a feeding table. A fixing support mechanism is arranged to fix and support the front end module so that the front end module is kept in a state after assembly. A slide on the transportation vehicle cooperates with a conveying belt on the feeding table to drive the transportation vehicle to move. A sensor arranged at a predetermined position of the feeding plate detects a metal detection piece to determine whether the transportation vehicle moves to the predetermined position. When the metal detection piece moves to the predetermined position, a blocking cylinder cooperates with a blocking block to position the transportation vehicle so that the transportation vehicle can stop at a position where it needs to stop.

[0013] Therefore, the front end module transportation device provided by the application can stably transport the front end module to the detection equipment, keep each part of the front end module in a predetermined position, and ensure that the front end module is kept in a predetermined state when the detection equipment detects the front end module, thereby ensuring the accuracy of detection.

[0038] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the front end module transportation device of the present application is specifically described below in combination with embodiments and drawings.

[0039] [EMBODIMENT]

[0040] The embodiment provides a front end module assembly device, transportation and detection system, which comprises a front end module assembly device 100, a front end module transportation device and a front end module detection device 400.

[0041] First, the front end module assembly device 100 is specifically described.

[0042] Figure 1 is a structural schematic diagram of a front end module assembly device in an embodiment of the present application.

[0043] As shown in Figure 1 , the front end module assembly device 100 is used for assembling a plurality of parts together to form an automobile front end module 200 (see Figure 8), including a base 10, a first rotating mechanism 20, a rotating table 30, a product mounting mechanism 40, a second rotating mechanism, and an assembly control unit 60.

[0044] The base 10 is a rectangular frame, and the first rotating mechanism 20 is mounted on a bottom plate 11 of the base 10 and used to drive the rotating table 30.

[0045] The rotating table 30 is a U-shaped frame and is mounted on the first rotating mechanism 20 through a vertical rotating shaft (not shown in the drawings). Under the driving of the first rotating mechanism 20, the rotating table 30 can rotate 180 degrees around the axis of the rotating shaft. The axis of the rotating shaft is defined as a first axis.

[0046] The product mounting mechanism 40 includes a product mounting frame 41, three mounting racks, six clamping assemblies, and auxiliary clamping members.

[0047] The product mounting frame 41 is a rectangular frame, and opposite left and right side edges thereof are connected to two opposite side edges of the rotating table 30 through horizontal rotating shafts, respectively. The connecting line of the two horizontal rotating shafts forms a second axis, and the second axis is located in a horizontal plane and perpendicular to the first axis.

[0048] The horizontal rotating shafts pass through the side edges of the rotating table, and one end thereof is connected to the product mounting frame 41 and the other end thereof is connected to the second rotating mechanism. Under the driving of the second rotating mechanism, the product mounting frame 41 can rotate ±90 degrees around the second axis.

[0049] The two second rotating mechanisms are marked as a second rotating mechanism 50a and a second rotating mechanism 50b, respectively.

[0050] The second rotating mechanisms are both composed of a motor and a bearing. The motor drives the bearing and the horizontal rotating shaft to rotate ±90 degrees around the second axis.

[0051] The three mounting racks are marked as a first mounting rack 42a, a second mounting rack 42b, and a third mounting rack 42c, respectively. The first mounting rack 42a and the second mounting rack 42b are mounted on a lower side edge 411 of the product mounting frame 41, and the third mounting rack 42c is mounted on an upper side edge 412 opposite to the lower side edge.

[0052] The three mounting racks 42 each have RPS positioning points, and there are 15 RPS positioning points 45 in total. The three-dimensional coordinates of each positioning point 45 are consistent with the three-dimensional coordinates of the parts mounted thereon on the automobile. The three-dimensional coordinates of the parts on the automobile are determined according to the position coordinates of the parts after they are mounted on the automobile and can accurately match other parts. Each part has a reference point, and when mounting, the reference point is aligned with the positioning point, and then assembly is performed. After all the parts are assembled into the automobile front end module, the automobile front end module is directly mounted on the automobile, so that each part is in the predetermined position where it should be, and the position, height, inclination, angle and other parameters of the parts meet the requirements and do not need to be adjusted additionally.

[0053] The six clamping assemblies are symmetrically installed on the product mounting frame 41, and are used for clamping the parts fixed on the mounting racks 42. The six clamping assemblies are the same in structure and are respectively marked as 43a-43f.

[0054] The auxiliary clamping piece is installed on the upper side 412 and is located at the third mounting rack 42c to clamp the parts mounted on the third mounting rack 42c.

[0055] The assembly control part 60 is electrically connected with the first rotating mechanism 20, the second rotating mechanism, the clamping assembly 43 and the auxiliary clamping piece, and is used for controlling the rotation of the first rotating mechanism 20 and the second rotating mechanism and the clamping of the clamping assembly and the auxiliary clamping piece on the parts fixed on the mounting racks 42.

[0056] The assembly control part 60 includes a control host and a plurality of foot switches arranged on the ground. The foot switches are electrically connected with the control host and are used for giving a start instruction of the control host.

[0057] Figure 2 It is a structural schematic view of the first rotating mechanism in the embodiment of the application.

[0058] As shown in Figure 2 , the first rotating mechanism 20 includes a cylinder 21, a rack 22, a first gear 23, a second gear 24, a slewing bearing 25, a roller bearing 26, a roller bearing and a connecting plate 27.

[0059] The output end of the cylinder 21 is connected with one end of the rack 22, and the other end of the rack 22 is engaged with the first gear 23. The first gear 23 is fixedly connected with the second gear 24 in an up-down mode, and the two gears rotate synchronously. The second gear 24 is engaged with the slewing bearing 25. The upper end of the slewing bearing 25 is provided with the connecting plate 27, the lower end is connected with the roller bearing 26, and the roller bearing is installed in the roller bearing 26. The roller bearing 26 is installed on the base 10. The connecting plate 27 supports the rotating workbench 30. A vertical rotating shaft is inserted into the roller bearing and the connecting plate 27, and the other end is fixedly connected with the bottom of the rotating workbench 30.

[0060] Under the control of the assembly control unit 60, the cylinder 21 drives the rack 22, thereby driving the first gear 23, the second gear 24, the rotating bearing 25 and the vertical rotating shaft to rotate synchronously, so that the rotating workbench 30 rotates around the first axis in a range of 180 degrees.

[0061] Figure 3 is a structural schematic diagram of the clamping assembly in the embodiment of the present application.

[0062] Taking the clamping assembly 43a as an example, as shown in Figure 3 , the clamping assembly includes a clamping cylinder 431, a clamping head 432 and a clamping mounting base 433.

[0063] The clamping cylinder 431 is a common cylinder, the output end of which is fixedly connected with one end of the clamping head 432, and the other end of the clamping head 431 is matched with the part to be clamped on the component. The clamping cylinder 431 and the clamping head 432 are both fixedly connected with the clamping mounting base 433, which is installed on the product mounting frame 41 through the clamping mounting base 433.

[0064] Under the control of the assembly control unit 60, the output end of the clamping cylinder 431 is extended to drive the clamping head 432 to clamp the component, and the screw is manually locked to install the component on the other component adjacent thereto, thereby completing the installation of the component. After the installation is completed, the assembly control unit 60 controls the output end of the clamping cylinder 431 to retract, thereby driving the clamping head 432 to retract and leave the component.

[0065] Figure 4 is a structural schematic diagram of the auxiliary clamping piece in the embodiment of the present application.

[0066] As shown in Figure 4 , the auxiliary clamping piece has an auxiliary cylinder 441, a positioning pin 442 and an auxiliary mounting base 443.

[0067] The auxiliary cylinder 441 and the positioning pin 442 are both fixedly connected with the auxiliary mounting base 443, which is installed on the product mounting frame 41 through the auxiliary mounting base 443. The auxiliary cylinder 441 is a common cylinder.

[0068] The positioning pin 442 is fixed on the output end of the auxiliary cylinder 441, and under the control of the assembly control unit 60, the positioning pin 442 is extended into the through hole of the component and the through hole on the third mounting bracket 42c as the output end is extended, so that the component is fixed on the third mounting bracket 42c, the screw is manually locked, and the component is installed on the other component adjacent thereto, thereby completing the installation of the component, and then the assembly control unit 60 controls the output end to retract, and the positioning pin 442 is extracted from the through hole and returns to the original position.

[0070] As shown in Figure 5 , the product installation pedal switch is stepped on, the product installation mechanism 40 is rotated 45 degrees, and the right vertical assembly, the left vertical assembly, the ECM, and the 11 door latch bridge are sequentially installed. During installation, manual installation is performed, the reference points on the parts are attached to or coincide with the corresponding RPS positioning points, the clamping cylinder in the clamping assembly is clamped by stepping on the clamping cylinder pedal switch after installation is completed, and then the screws are locked.

[0074] As shown in Figure 7 , the product installation pedal switch is stepped on, the product installation mechanism 40 is rotated 0 degrees, that is, the vertical non-rotating state, and the AVAS assembly, the Holmes, the connecting cover, the door lock, the Vito element, the ambient temperature sensor, and the silk cap are sequentially installed. The installation steps are the same as in Figure 5 , and will not be repeated.

[0075] Figure 8 is the structure schematic view when the rotating workbench is turned over 180 degrees in the embodiment of the present application.

[0076] As shown in Figure 8 , the axis rotation pedal switch is stepped on, the rotating workbench 30 is rotated 180 degrees, and the refrigerator assembly, the washing bottle, the dryer receiver, the radiator hose inlet, the collision sensor, and the latch cable connection support are sequentially installed. The installation steps are the same as in Figure 5 , and will not be repeated. At this point, the automobile front end module 200 is assembled.

[0077] During the assembly process of the automobile front end module 200, the corresponding lines are installed in the assembly process as needed, and finally all the lines are collected into two line connectors.

[0078] Next, the front end module transport device is described in detail. The automobile front end module 200 is referred to as front end module 200 hereinafter. The front end module 200 is assembled by a plurality of components, and has an overall arc shape with a plurality of protrusions at the bottom.

[0079] The front end module transport device includes a transport vehicle 3-10, a feeding table 3-20, and a detection control unit 4-60 (see Figure 14 ), which is used to transport the assembled front end module 200 to the detection equipment 400.

[0080] Figure 9 is a structural schematic diagram of the transport vehicle in the embodiment of the present application. Figure 10 is a structural schematic diagram of the transport vehicle from another angle in the embodiment of the present application.

[0081] As shown in Figure 9 , 10 , the transport vehicle 3-10 includes a fixed support mechanism 3-11, a proximity sensor 3-12, an aviation plug 3-13, a linear guide rail 3-14, a sliding bar 3-15, a detection metal piece 3-16, and a blocking block 3-17.

[0082] The fixed support mechanism 3-11 includes a vehicle frame 3-111, four universal wheels 3-112 mounted at the bottom of the vehicle frame 3-111, a vehicle plate 3-113 placed on the top of the vehicle frame 3-111, and a fixed support assembly fixed on the vehicle plate 3-113. Four weight-reducing holes 3-114 are formed in the vehicle plate 3-113. The linear guide rail 3-14 is mounted at the bottom of the vehicle plate 3-113.

[0083] The proximity sensor 3-12 and the aviation plug 3-13 are both mounted on the vehicle plate 3-113, and the two proximity sensors 3-12 are respectively electrically connected to the two aviation plugs 3-13 to detect the metal parts prone to falling off on the front end module 200. The two aviation plugs 3-13 are also respectively electrically connected to two line junctions, and the lines have a certain length.

[0084] When the aviation plug 3-13 is connected to the external power supply, the proximity sensor 3-12 is powered on to detect whether there is a metal part within 3-5 mm in front of it. If there is a metal part, the display screen of the detection control unit 4-60 displays yes, otherwise no. In actual application, the corresponding proximity sensor can be arranged at the corresponding position of the vehicle plate 3-113 or the fixed support assembly according to the position and number of the metal parts prone to falling off on the front end module 200.

[0085] The two sliding bars 3-15 are arranged in parallel at the bottom of the vehicle frame 3-111. The detection metal piece 3-16 is also mounted at the bottom of the vehicle frame 3-111, and the blocking block 3-17 is mounted on the front side of the vehicle frame 3-111.

[0086] The fixed support assembly is installed on the upper surface of the vehicle plate 3-113, and includes a plurality of fixed supports, namely 2 upper fixed supports 3-115, 2 side fixed supports 3-116, 3 front end fixed supports 3-117, and 2 bottom end fixed supports 3-118. The heights of the upper fixed supports 3-115, the side fixed supports 3-116, the front end fixed supports 3-117, and the bottom end fixed supports 3-118 decrease in turn.

[0087] The 2 upper fixed supports 3-115 are symmetrically arranged on the vehicle plate 3-113 along the length extension direction of the automobile module 200, and are used for positioning and supporting the parts at the upper part of the automobile front end module 200.

[0088] The 2 side fixed supports 3-116 are symmetrically arranged on the vehicle plate 3-113 along the length extension direction of the automobile module 200, and are located in front of the upper fixed supports 3-115, and are used for positioning and supporting the parts at the two ends of the automobile front end module 200.

[0089] The 3 front end fixed supports 3-117 are uniformly arranged in turn on the vehicle plate 3-113 along the length extension direction of the automobile module 200, and are located in front of the side fixed supports 3-116, and are used for positioning and supporting the parts at the front end of the automobile front end module 200.

[0090] The 2 bottom end fixed supports are installed between the 2 side fixed supports 3-116, and are used for positioning and supporting the parts at the bottom end of the automobile front end module 200.

[0091] The structures of the plurality of fixed supports in the fixed support assembly are similar, and the top end of each fixed support has a groove, which matches the position and shape of the plurality of protrusions at the bottom of the front end module 200 in a clamping manner, so as to stably support the front end module 200 and keep the front end module 200 in a predetermined state, thereby ensuring the position accuracy and stability of the parts on the front end module 200 during the entire transportation process.

[0092] Since the structures of the plurality of fixed supports are similar, only the front end fixed support 3-117 is taken as an example for description.

[0093] Figure 11 is a structural schematic view of the fixed support in the embodiment of the present application.

[0094] As shown in Figure 11 , the front end fixed support 3-117 has a groove 3-117a.

[0095] After the front end module 200 is placed on the transport vehicle 3-10, the placed state of the to-be-transported front end module 200 is shown in Figure 12 .

[0096] Figure 13 Fig. 1 is a structural schematic diagram of the feeding table in an embodiment of the present application; Figure 14 Fig. 2 is a structural schematic diagram of the feeding table and the detection device in an embodiment of the present application; Figure 15 Fig. 3 is a process schematic diagram of the transport vehicle moving to the detection device in an embodiment of the present application.

[0097] As shown in Fig. 1, the feeding table 3-20 comprises a feeding plate 3-21 and two transport belts 3-22, two sensors 3-23 and two blocking cylinders 3-24 arranged on the feeding plate 3-21. Figures 13-15

[0098] The feeding plate 3-21 is a rectangular plate comprising a feeding area 3-211, a first detection station 3-212, a second detection station 3-213 and a detection area 3-214 connected in sequence. The detection area 3-214 is located below the detection mechanism of the front-end module detection device 400.

[0099] The transport belts 3-22 are matched with the slides 3-14. The two transport belts 3-22 are parallel to each other, and the distance between the two transport belts 3-22 is equal to the distance between the two slides 3-14.

[0100] The transport belts 3-22 are ball ring belts, which are driven to circulate and roll under the drive of the motor, and drive the slides 3-14 located thereon to move together, so as to move the transport vehicle 3-10 on the feeding table 3-20.

[0101] The first detection station 3-212 and the second detection station 3-213 are respectively provided with a sensor 3-23 and a blocking cylinder 3-24. The sensor 3-23 is installed near the blocking cylinder 3-24, and is used to detect whether the detection metal piece 3-16 on the transport vehicle 3-10 moves above the sensor 3-23. When it is detected that there is a detection metal piece 3-16 above, the detection control part 4-60 controls the active end of the blocking cylinder 3-24 to be lifted upward and abut against the blocking block 3-17 of the transport vehicle 3-10, so that the transport vehicle 3-10 is stopped at this position, thereby realizing the positioning of the transport vehicle 3-10.

[0102] The transport vehicle 3-10 is manually pushed into the feeding area 3-211, the detection control part 4-60 controls the transport belts 3-22 to start, and the transport vehicle 3-10 is transported to the first detection station 3-212. The sensor 3-23 at the first detection station 3-212 senses the arrival of the transport vehicle 3-10, and the blocking cylinder 3-24 at the first detection station 3-212 lifts the transport vehicle 3-10 to temporarily stop at the first detection station 3-212.

[0103] ​When there is no transport vehicle 3-10 at inspection station 2 (3-213), the detection control unit (4-60) lowers the blocking cylinder 3-24 at inspection station 1 (3-212), and the conveyor belt 3-22 transports the transport vehicle 3-10 to inspection station 2 (3-213). The sensor 3-23 at inspection station 2 (3-213) senses that the transport vehicle 3-10 has arrived, and the blocking cylinder 3-24 at inspection station 2 (3-213) lifts up, pausing the transport vehicle 3-10 at inspection station 2 (3-213). Similarly, when there is no transport vehicle 3-10 at inspection area 3-214, the detection control unit (4-60) lowers the blocking cylinder 3-24 at inspection station 2 (3-213), and the conveyor belt 3-22 transports the transport vehicle 3-10 to inspection area 3-214, preparing to enter the detection procedure.

[0104] The front-end module inspection equipment 400 detects whether the front-end module 200 transported by the front-end module transport device is in the predetermined assembly state. The front-end module 200 has multiple positioning points, multiple holes, components, and wiring. The positioning points on the front-end module 200 correspond one-to-one with the positioning points on the mounting bracket during assembly, and their three-dimensional coordinates are consistent with the three-dimensional coordinates of the components on the vehicle. Components include all parts that make up the front-end module. In the following description, only easily detachable metal fittings, door locks, and connecting covers are used as examples to illustrate how to inspect components. Actual inspection also includes the inspection of other components on the front-end module, using the corresponding component inspection units for position detection and / or flatness detection.

[0105] The position of the hole on the front-end module 200 is defined as the first predetermined position, the position of the metal fitting is defined as the second predetermined position, the position of the door lock is defined as the third predetermined position, and the position of the connecting cover is defined as the fourth predetermined position.

[0106] The following is a detailed description of the front-end module testing equipment 400.

[0107] Figure 16 This is a schematic diagram of the detection device in an embodiment of the present invention.

[0108] like Figure 14 , 16 As shown, the front-end module testing equipment 400 includes a mounting frame 4-10 and a positioning detection mechanism 4-20, a lifting mechanism 4-30, a positioning mechanism 4-40, and a testing mechanism 4-50 mounted on the mounting frame 4-10. The testing mechanism 4-50 is mounted on the positioning mechanism 4-40.

[0109] The feeding platform 3-20 is located inside the mounting frame 4-10, and its testing area 3-214 is located below the positioning mechanism 4-40 and the testing mechanism 4-50, which facilitates the testing of the front-end module 200 transported by the transport vehicle 3-10.

[0110] The in-position detection mechanism 4-20 detects whether the transport vehicle 3-10 moves to the detection position, i.e. whether the detection area 3-214 is located at the required position below the positioning mechanism and the detection mechanism, and positions the transport vehicle 3-10 when detecting that the transport vehicle 3-10 is in the detection position.

[0111] The lifting mechanism 4-30 lifts the vehicle plate 3-113 on which the front-end module 200 is placed, the positioning mechanism 4-40 fixes the front-end module 200, the lifting mechanism 4-30 lowers the vehicle plate 3-113, and then the detection mechanism 4-50 detects whether the front-end module 200 is in the predetermined assembly state. After the detection is completed, the lifting mechanism 4-30 lifts the vehicle plate 3-113 to support the front-end module 200, the positioning mechanism 4-40 exits, the lifting mechanism 4-30 lowers the vehicle plate 3-113 and the front-end module 200 together, and the transport vehicle 3-10 transports the front-end module 200 which has completed the detection.

[0112] Figure 17 Fig. 4 is a structural schematic view of the rack, the in-position detection mechanism and the lifting mechanism in the embodiment of the present application; Figure 18 Fig. 5 is a structural schematic view of the rack, the in-position detection mechanism and the lifting mechanism in the embodiment of the present application from another angle.

[0113] As shown in Figs. 4 and 5, the in-position detection mechanism 4-20 includes two in-position detection sensors 4-21 and two in-position blocking cylinders 4-22 which are symmetrically installed on the rack 4-10. Figure 17 18 The in-position detection sensor 4-21 detects the metal part (not shown in the drawing) at the bottom of the vehicle frame 3-111, indicating that the transport vehicle 3-10 moves to the detection position, and transmits the in-position signal to the detection control unit 4-60. Then the detection control unit 4-60 sends an instruction to the in-position blocking cylinder 4-22, and the in-position blocking cylinder 4-22 rises to block the transport vehicle 3-10 at this position, thereby limiting the movement of the transport vehicle 3-10 in the left and right directions and the front and back directions.

[0114] The lifting mechanism 4-30 includes two primary positioning cylinders 4-31, two fine positioning cylinders 4-32 which are symmetrically installed on the rack 4-10, and two primary positioning members 4-33 and two fine positioning members 4-34 which are symmetrically installed at the bottom of the vehicle plate 3-113. The position of the vehicle plate 3-113 where the primary positioning members 4-33 and the fine positioning members 4-34 are installed has a through hole.

[0115] The lifting mechanism 4-30 includes two primary positioning cylinders 4-31, two fine positioning cylinders 4-32 which are symmetrically installed on the rack 4-10, and two primary positioning members 4-33 and two fine positioning members 4-34 which are symmetrically installed at the bottom of the vehicle plate 3-113. The position of the vehicle plate 3-113 where the primary positioning members 4-33 and the fine positioning members 4-34 are installed has a through hole.

[0116] Figure 19 Fig. 6 is a structural schematic view of the primary positioning cylinder in the embodiment of the present application.

[0117] ​The primary positioning cylinder 4-31 and the fine positioning cylinder 4-32 have the same structure, both including a cylinder body and an extension part. Take the primary positioning cylinder 4-31 as an example for description.

[0118] As shown in Figure 19 , 18 , after the transport vehicle 3-10 is in place, the extension part 4-311 of the primary positioning cylinder 4-31 rises from the cylinder body 4-312, passes through the primary positioning part 4-33 and the through hole, and then the fine positioning cylinder 4-32 acts, passing through the fine positioning part 4-34 and the corresponding through hole. The extension part of the fine positioning cylinder 4-32 lifts the plate 3-113 and the front end module 200 to the topmost position where the extension part can rise, and then the positioning mechanism 4-40 and the detection mechanism 4-50 are lowered. Among them, Figure 18 , the left fine positioning cylinder 4-32 is in the lifting state, and the right fine positioning cylinder 4-32 is in the non-lifting state.

[0119] Figure 20 is a structural schematic diagram of the positioning mechanism and the detection mechanism in the embodiment of the present application; Figure 21 is a state diagram of the positioning mechanism before positioning the front end module in the embodiment of the present application; Figure 22 is a state diagram of the positioning mechanism after positioning the front end module in the embodiment of the present application.

[0120] As shown in Figures 19-22 , the positioning mechanism 4-40 includes a positioning frame 4-41 mounted on the rack 4-10, a plurality of positioning detection points 4-42 and a positioning part provided on the positioning frame 4-41.

[0121] The positioning detection points 4-42 are consistent with the three-dimensional coordinates of the positioning points, and are used for positioning the front end module 200.

[0122] The positioning part includes a positioning unit and a pressing unit, the positioning unit includes a plurality of positioning cylinders 4-43 and positioning pins 4-44 connected with the positioning cylinders 4-43. The positioning cylinders 4-43 are arranged according to the shape of the front end module 200, and the positioning cylinders 4-43 drive the positioning pins to insert into the corresponding positions of the front end module 200. The pressing unit is a pressing cylinder 4-45, which realizes the positioning and fixing of the front end module 200 together with the positioning unit. Then the extension part of the fine positioning cylinder 4-32 is lowered, and the plate 3-113 is lowered together. In the process of the fine positioning cylinder 4-32 driving the plate 3-113 to rise or fall, the linear guide rail 3-14 at the bottom of the plate 3-113 moves along the guide (not marked in the figure) mounted on the rack 4-10, avoiding the position deviation of the plate 3-113 during the movement. Without the support and fixation of the transport vehicle 3-10, the front end module 200 is in a natural state, simulating its state on the car, so that the results of the subsequent detection are more accurate.

[0123] Figure 22 is a schematic view of installation of hole position detecting unit and metal part sensor in the embodiment of the present application; Figure 23 is a schematic view of installation of part detecting unit in the embodiment of the present application.

[0124] As shown in Figure 17 , 23 and 24, the detecting mechanism 4-50 includes wire harness detecting unit, hole position detecting unit and part detecting unit.

[0125] The wire harness detecting unit includes wire harness cylinder 4-501 installed on the frame 4-10 and wire harness detecting plug 4-502 connected with the wire harness cylinder 4-501. The wire harness detecting plug 4-502 matches with the aviation plug 3-13 on the vehicle plate 3-113 and is inserted into the aviation plug 3-13 under the drive of the wire harness cylinder 4-501 to detect the continuity of the wire. Since the wire has a certain length, the separation of the front end module 200 and the vehicle plate 3-113 does not affect the detection of the wire.

[0126] The hole position detecting unit includes a plurality of hole probes 4-503, alarm (not shown in the figure) installed on the hole probes and hole detecting cylinder 4-504 corresponding to the hole probes 4-503. When the corresponding hole probe 4-503 is not inserted into the corresponding hole, the alarm at the place alarms and is displayed on the display screen of the detecting control unit 4-60.

[0127] The part detecting unit includes metal fitting detecting unit, door lock detecting unit and connecting cover detecting unit.

[0128] The metal fitting detecting unit is composed of a plurality of metal part sensors 4-505, each of which is arranged at the corresponding metal fitting position to detect whether the metal fitting prone to fall off is in its position, i.e. the second predetermined position.

[0129] The metal part sensor 4-505 is the same as the proximity sensor 3-12 in type and function and detects whether there is a metal part within 3mm-5mm in front of it after being powered on. If there is a metal part, it is displayed on the display screen of the detecting control unit 4-60, otherwise it is not displayed. In actual application, corresponding sensors can be arranged at corresponding positions according to the positions and number of metal parts prone to fall off on the front end module 200.

[0130] The door lock detecting unit is used to detect whether the door lock is in the third predetermined position and includes door lock cylinder 4-506 and door lock detecting sensor 4-507. The door lock detecting sensor 4-507 is turned over above the door lock 201 under the drive of the door lock cylinder 4-506 to detect whether the door lock 201 is in its predetermined position.

[0131] The connection cover detection unit is used to detect whether the connection cover 202 is in the fourth predetermined position.

[0132] The connection cover detection unit comprises a connection cover positioning member 4-508, a connection cover displacement sensor 4-509, a connection cover detection cylinder 4-510, and a connection cover limiting member 4-511.

[0133] The connection cover positioning member 4-508 positions and fixes the connection cover 202, and the installation position thereof is determined by three-dimensional coordinates.

[0134] The connection cover detection cylinder 4-510 drives the connection cover displacement sensor 4-509 to move, and detects the flatness of the connection cover 202. The connection cover displacement sensor 4-509 tests the distance from the connection cover 202, and if the distance is within the set range, the flatness is qualified, otherwise it is unqualified. The connection cover limiting member 4-511 assists the displacement sensor 4-509.

[0135] After the detection is completed and all the components to be detected are qualified, the door lock and the connection plate screw are manually locked. After the operation is completed, the detection mechanism returns to the original position, the fine positioning cylinder 4-32 is lifted, the positioning mechanism returns to the original position, the detection mechanism goes up, the blocking cylinder 4-22 returns to the original position, and the transport vehicle 3-10 is automatically sent out by the transport belt 3-22 of the feeding table 3-20, and the detection is completed. The transport vehicle 3-10 ensures that the assembly state of the front end module 200 before detection does not change, and also ensures that the overall state after detection is completed does not change.
