[0002] Industrial automation is one of the key technologies in the field of modern manufacturing in the 20th century. It refers to the information processing and process control such as measurement and manipulation of machinery and equipment or production processes without direct human intervention.

However, this assembly method has many problems in terms of equipment stability, equipment beat, overall noise, overall debugging, post-maintenance and delivery time. For example, the stability is poor, and multiple people need to coordinate and cooperate during debugging; when expanding production or adjusting processes, there is insufficient flexibility. At the same time, there are many parameters that need to be adjusted and optimized for both cylinders and modules. For example, the speed loop and position loop gain parameters of the module will affect the motion accuracy and stability due to factors such as load and motion speed. The air pressure of the cylinder also needs to be adjusted according to the load conditions to ensure the reliability and safety of the motion.

[0038] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0039] like Figure 1 and Figure 2 As shown, the modular high-speed assembly conveyor line described in the present invention includes a workbench 1, a transmission module 2, a handling module 3, a detection module 4 and a pressing module 5 arranged on the workbench 1; the transmission module 2 is used to convey the carrier, the handling module 3, the detection module 4 and the pressing module 5 are arranged in sequence along the carrier conveying direction, the handling module 3 can transfer the corresponding part of the workpiece on the carrier and complete the workpiece assembly, the detection module 4 is used to detect the various components after the assembly is completed, and the pressing module 5 is used to crimp the assembled workpiece.

[0040] The transmission module 2 includes a fork mechanism 21 that drives the carrier to move along the conveying direction and a transmission slide 22 for the carrier to slide. The fork mechanism 21 is arranged below the transmission slide 22, and includes a driving module and a fork assembly. The fork assembly realizes reciprocating motion along the conveying direction and lifting motion at the same time under the power of the driving module to drive the carrier to move from one workstation to the next.

[0041] In the following description, the conveying direction is referred to as the X direction, the direction perpendicular to the X direction on the same horizontal plane is referred to as the Y direction, and the vertical direction is referred to as the Z direction.

[0042] Specifically, Figures 3 to 6 As shown, the fork assembly includes a fork plate 211 connected to the output end of the driving module. The locating pin on the upper end surface of the fork plate 211 corresponds to the locating hole on the carrier. The lifting and lowering movement of the fork plate 211 realizes the plug-in and pull-out cooperation between the locating pin and the locating hole. The fork plate 211 reciprocates along the X direction and drives the carrier to move step by step.

[0043] The driving module includes a driving motor 212, which drives the fork plate 211 to realize the fork moving component and the fork lifting component to respectively realize the reciprocating motion and lifting motion along the X direction.

[0044] The fork moving assembly is installed under the workbench 1 through the first mounting plate 11, and includes an X-axis fork cam 213, an X-axis fork rocker rod 214 and a fork moving block 220. The fork plate 211 is fixedly connected to the fork moving block 220, and moves along the X direction with the cooperation of the X-axis fork rocker rod 214 and the X-axis fork cam 213.

[0045] In this embodiment, the X-axis fork cam 213 includes a cam turntable and a fork cam shaft that drives the cam turntable to rotate. A cam groove is provided on the cam turntable. The bottom of the X-axis fork rocker arm 214 is hinged to the first mounting plate 11 through a rotating shaft. Rollers are provided in the middle and top of the X-axis fork rocker arm 214. The roller in the middle is rollingly connected to the track of the cam groove. A vertical groove extending along the Z direction is provided on the fork moving block 220, and the top roller rolls and moves in the vertical groove.

[0046] The fork lifting assembly includes a fork lifting plate 215, a Z-axis fork cam 216 and a Z-axis fork rocker 217. The Z-axis fork rocker 217 is a lever structure. One end of the Z-axis fork rocker 217 cooperates with the Z-axis fork cam 216, and the other end is connected to the fork lifting plate 215 and presses the fork lifting plate 215 down in the vertical direction through the downward pressing moving block.

[0047] The fork lifting members 218 are provided on both sides of the fork lifting plate 215. In this embodiment, the fork lifting members 218 are fork lifting springs. The bottom end of the fork lifting spring is installed below the workbench 1 through the second mounting plate 12, and the top end is fixedly connected to the fork lifting plate 215. During the vertical descent of the fork lifting plate 215, the fork lifting spring is in a compressed state. With the rotation of the fork vertical cam, when the fork vertical shifting rocker releases the fork lifting plate 215, the fork lifting spring is reset, thereby driving the fork lifting plate 215 to achieve lifting.

[0048] Furthermore, a fork linear rail 219 extending along the conveying direction is provided between the fork plate 211 and the fork lifting plate 215. The fork moving block 220 rises and falls with the fork lifting plate 215, and under the drive of the fork translation cam, the fork plate 211 is driven to slide and connect to the fork lifting plate 215 through the fork linear rail 219.

[0049] A shift fork synchronous belt assembly is provided between the driving motor 212 and the shift fork moving assembly and the shift fork lifting assembly. The shift fork synchronous belt assembly includes two groups of driving wheels connected to the motor shaft, and two groups of driven wheels respectively connected to the two groups of driving wheels through synchronous belt transmission. The two groups of driven wheels are respectively connected to the X-axis shift fork cam 213 and the Z-axis shift fork cam 216 through the first rotating rod 6 and the second rotating rod 7. Furthermore, the first rotating rod 6 and the shift fork cam shaft are connected through a commutator transmission.

[0050] In this embodiment, the transport module 3, the detection module 4 and the press-fitting module 5 all adopt a cam drive structure; the second rotating rod 7 is provided with a synchronously rotating driving wheel 8, which extends along the X-axis and is meshed with the driving wheel 8 for transmission with a long-axis gear 9. By utilizing the length of the long-axis gear 9 to achieve meshing with multiple gears, the transport module 3 and the press-fitting module 5 respectively obtain power through the gears meshing with the long-axis gear 9.

[0051] like Figures 7 to 10 As shown, the handling module 3 includes a material moving assembly that can drive various parts of the workpiece to move in a vertical direction and in a direction perpendicular to the conveying direction, so as to complete the transfer and installation of various parts of the workpiece.

[0052] In the following description, the conveying direction is referred to as the X direction, the direction perpendicular to the X direction on the same horizontal plane is referred to as the Y direction, and the vertical direction is referred to as the Z direction.

[0053] The transport module 3 also includes an assembly support plate 31, a Y-axis transfer assembly 32 that drives the material transfer assembly to move along the Y direction, and a Z-axis transfer assembly 33 that drives the material transfer assembly to move along the Z direction. The Z-axis transfer assembly 33 includes a Z-axis transfer cam 331, a Z-axis transfer plate 332, and a Z-axis guide rod 333 that drives the Z-axis transfer plate 332 to rise and fall. One end of the Z-axis guide rod 333 is rollingly connected to the cam surface of the Z-axis transfer cam 331 through a roller. A vertical linear rail is provided between the assembly support plate 31 and the Z-axis transfer plate 332. The Z-axis transfer plate 332 rises and falls with the Z-axis guide rod 333 and is slidably connected to the assembly support plate 31 through the vertical linear rail.

[0054] The Y-axis transfer assembly 32 includes a Y-axis transfer cam 321, a Y-axis transfer swing rod 322 and a Y-axis transfer plate 323. The material transfer assembly is connected to one end of the Y-axis transfer plate 323 and moves in the horizontal direction under the cooperation of the Y-axis transfer swing rod 322 and the Y-axis transfer cam 321. The material transfer assembly can adopt clamping or adsorption to take materials according to product needs.

[0055] In this embodiment, the Z-axis transfer plate 332 and the Y-axis transfer plate 323 are located on the same side of the assembly support plate 31 and are connected by a Y-axis transfer linear rail, which extends in the Y direction. The assembly support plate 31 is provided with a hollow for the Z-axis guide rod 333 to move in the vertical direction. While the Y-axis transfer plate 323 is raised and lowered with the Z-axis transfer plate 332, it moves relative to the Z-axis transfer plate 332 in the Y direction under the drive of the Y-axis transfer cam 321. This structure makes the material transfer assembly stable in action and fast in handling speed. Moreover, the Z-axis guide rod 333 extending in the Z direction drives the Z-axis transfer plate 332 and the Y-axis transfer plate 323 to rise and fall, so that a large load can be achieved.

[0056] The Z-axis transfer cam 331 and the Y-axis transfer cam 321 are connected by a synchronous shaft that is rotatably connected to the assembly support plate 31, and the synchronous shaft rotates under the drive of the synchronous transmission assembly. The synchronous transmission assembly includes two sets of synchronous wheels that are spaced apart on the assembly support plate 31, and the two sets of synchronous wheels are connected by a synchronous belt transmission, one set of synchronous wheels is installed on the synchronous shaft, and the other set of synchronous wheels cooperates with the long shaft gear 9 through two meshing gears.

[0057] like Fig.11 and Fig.12 The press-fitting module 5 includes a press-fitting support plate 51, a Z-axis driving assembly 52 and a synchronous transmission assembly respectively arranged on opposite sides of the press-fitting support plate 51, and a pressing assembly 53 connected to the Z-axis driving assembly 52; under the transmission action of the synchronous transmission assembly, the Z-axis driving assembly 52 drives the pressing assembly 53 to realize the pressing of the assembled product.

[0058] The Z-axis driving assembly 52 includes a Z-axis press-fit cam 521, a Z-axis press-fit rocker arm 522 and a press-fit moving block 523. One end of the Z-axis press-fit rocker arm 522 is hinged to the press-fit support plate 51 through a rotating shaft. The middle part and the free end of the Z-axis press-fit rocker arm 522 are provided with rollers. The roller in the middle part cooperates with the Z-axis press-fit cam 521. The press-fit moving block 523 is provided with a horizontal groove extending in the horizontal direction, and the roller at the free end rolls and moves in the horizontal groove.

[0059] The pressing assembly 53 is fixedly connected to the pressing moving block 523 through a pressing connecting plate, and a vertical straight rail is provided between the pressing connecting plate and the pressing support plate 51. The pressing assembly 53 is slidably connected to the pressing support plate 51 through the vertical straight rail during the lifting and lowering process of the pressing moving block 523.

[0060] The bottom of the press-fit support plate 51 is also hinged with a swing cylinder 54, and the piston rod end of the swing cylinder 54 is pivotally connected to the free end of the Z-axis press-fit swing rod 522. When the piston rod of the swing cylinder 54 is extended and retracted, the Z-axis press-fit swing rod 522 swings around the rotation axis.

[0061] When the pressing assembly 53 descends to the pressing position along with the pressing moving block 523 , the piston rod of the swing cylinder 54 contracts, driving the Z-axis pressing swing rod 522 to perform the pressing operation, and the downward pressure of the pressing assembly 53 is accurately controlled by the swing cylinder 54 .

[0062] After the pressing is completed, the piston rod of the swing cylinder 54 is pushed out, driving the Z-axis press-fitting rocker 522 to swing and disengage from the press-fitting cam, and the pressing assembly 53 no longer continues to rise and fall for the pressing action, thereby reducing the mechanical wear of related components, extending the service life, and reducing maintenance costs.

[0063] The Z-axis press-fitting cam 521 is connected to the press-fitting support plate 51 by means of a synchronous shaft that is rotatably connected, and the synchronous shaft is driven to rotate by a synchronous transmission assembly. The synchronous transmission assembly has been described in detail in the handling module 3 and will not be described again here.

[0064] like Fig.13 and Fig.14 The detection module 4 can be arranged after each process to monitor each process, including whether it is assembled and pressed in place; the detection module 4 includes a detection component 41 for displacement detection of the product on the carrier, a detection cam 42 installed on the second rotating rod 7 and rotating synchronously with the second rotating rod 7, and a detection swing rod 43 that cooperates with the detection cam 42 to control the lifting of the detection component 41. The structure of the detection component 41 can be designed according to the needs of the product to be detected.

[0065] In this embodiment, the detection swing rod 43 is a lever structure, including a fulcrum and a driving end and an operating end rotating around the fulcrum. The driving end cooperates with the detection cam 42, and the operating end drives the detection component 41 to lift.

[0066] Specifically, the driving end is connected to the contour surface of the detection cam 42 by rolling through a roller. The operating end is connected to the detection assembly 41 through the detection lifting block 44. Further, the operating end is pivotally connected to a roller that is in rolling contact with the lower end surface of the detection lifting block 44, and the operating end drives the detection lifting block 44 to move up and down under the swing of the detection swing rod 43.

[0067] A tension spring 45 is provided on the second mounting plate 12, and the free end of the tension spring 45 performs a lifting and lowering movement along with the detection lifting block 44. When the detection component 41 is lifted along with the lifting block, the tension spring 45 is stretched and stores elastic potential energy. When the detection cam 42 rotates to drive the detection component 41 to descend, the contraction force of the tension spring 45 causes the detection component 41 to descend along a predetermined trajectory.

[0068] In order to achieve synchronous lifting and lowering of multiple groups of detection components 41, the multiple groups of detection components 41 are connected by the same supporting plate 46, which extends along the X direction, and both ends of the supporting plate 46 in the extension direction are connected to the detection lifting block 44 through the detection lifting plate, and are synchronously lifted and lowered with the detection lifting block 44 under the swing of the detection swing rods 43 on both sides.

[0069] Furthermore, the fulcrums of the detection swing arms 43 on both sides are connected by a third rotating rod 47. Both ends of the third rotating rod 47 are provided with a third mounting plate 13 fixedly connected to the lower end surface of the workbench 1. Both ends of the third rotating rod 47 are rotatably connected to the third mounting plates 13 at both ends through bearings. Under the synchronous coordination of the third rotating rod 47, the swing of the detection swing arms 43 on both sides can ensure the synchronous lifting and lowering of the detection assembly 41.

[0070] Since the handling module 3, the detection module 4 and the pressing module 5 are all modularly designed, they can be arranged in combination according to the assembly process requirements, and the modules can be quickly replaced. Multiple groups can also be arranged in sequence along the carrier conveying direction according to assembly needs. Moreover, each module is cam-driven, thereby reducing control program programming, not increasing the pressure on the control system, and subsequent maintenance and debugging are also simple.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
