Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing production of vehicle motors, and in particular to an intelligent assembly device for vehicle motor end covers. Background Art

[0002] In recent years, benefiting from the rapid development of new energy vehicles and intelligent vehicles, various motors in vehicles have been widely used, driving the rapid development of the entire motor industry.

[0003] The motor assembly structure is a mechanical device for assembling various components of the motor. Its main function is to ensure that the core components of the motor, such as the front end cover, rear end cover, rotor, and stator, can be installed in a predetermined order. In a conventional motor assembly structure, the rear end cover of the motor usually relies on mechanical jigs and positioning mechanisms to complete fixation and positioning. For example, by placing the motor housing in a groove in a mechanical jig, subsequent assembly can be carried out. In the standard assembly process, its high repeatability and stability can meet the production requirements of ordinary motors. In the production process of automotive motors, the installation methods of the motor housing, end cover, and shaft need to be comprehensively designed in combination with mechanical strength, coaxiality requirements, sealing performance, and assembly processability.

[0004] Example of the prior art 1, referring to the patent document CN119448705B, discloses a motor end cover assembly device, which includes a turntable assembly and a housing feeding assembly, an end cover feeding assembly, and an assembly assembly arranged in sequence around the turntable assembly. The motor housing is provided with motor assembly holes; the turntable assembly is provided with housing positioning holes; a positioning and rotating assembly is installed at a position corresponding to the housing positioning holes on the turntable assembly; the positioning and rotating assembly includes a movable part arranged on one side of the housing positioning hole and capable of moving away from or approaching the housing positioning hole. The movable part includes a first positioning wheel arranged close to the housing positioning hole; the positioning and rotating assembly further includes a housing supporting part arranged below the housing positioning hole, and the housing supporting part includes a second positioning wheel facing the bottom wall of the motor housing.

[0005] Example of the prior art 2, referring to the patent document CN114012378A, discloses an automatic motor end cover sealing assembly device, including a frame, a rectangular conveying device arranged on the surface of the frame, a motor assembly jig that can be transported on the rectangular conveying device, a sealing feeding device, an end cover feeding device, an end cover alignment device, an end cover rotation and pressing device, and a screw tightening device installed on the frame and located on one side of the rectangular conveying device and arranged in sequence; the present invention sequentially performs sealing part feeding, end cover feeding, end cover alignment, end cover rotation and pressing, and end cover screw tightening.

[0006] In summary, the devices provided by Technical Example 1 and Technical Example 2 have similar limitations. For example: 1. The functions are single, and it can only achieve the installation of the motor end cover and the motor housing, and cannot achieve the installation functions of other accessories; 2. Its structure is only applicable to micro motors and cannot support the assembly of motors with slightly larger sizes; 3. The detection method in the device is single and cannot achieve a high-precision assembly effect; 4. The compatibility of the tooling is poor and cannot be replaced. Therefore, the entire device is only applicable to the assembly of a single motor. Summary of the Invention

[0007] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides an intelligent assembly device for a vehicle motor end cover and its assembly method.

[0008] The technical solution for the present invention to solve its technical problems is: an intelligent assembly device for a vehicle motor end cover, including: A working platform, on which an electric control system is provided; A rail-type material conveying mechanism, which is transversely spanned on the working platform. A movable motor housing tooling table is provided on the rail-type material conveying mechanism; the motor housing tooling table has a motor support base and a through hole penetrating the motor housing tooling table and the motor support base; a first optical sensor transceiver module is provided on the rail-type material conveying mechanism, and a light reflection positioning block is provided on the motor housing tooling table. During the lateral movement of the motor housing tooling table relative to the rail-type material conveying mechanism, the light reflection positioning block moves laterally relative to the optical sensor transceiver module; A CCD vision detection mechanism. The first optical sensor transceiver module divides the rail-type material conveying mechanism into a feeding section and a discharging section, and the CCD vision detection mechanism is located directly above the feeding section; A transfer platform, which is longitudinally arranged at the upper end of the working platform, and the transfer platform is located behind the rail-type material conveying mechanism; A transfer mechanism, which is provided on the transfer platform, and the transfer mechanism is used to transfer the motor end cover into the motor housing on the motor housing tooling table; A support platform, which is provided at the lower end of the working platform; A pressing shaft mechanism, which is provided on the support platform. The transfer mechanism is used to push the motor shaft up into the motor housing on the motor housing tooling table and press it together with the motor end cover.

[0009] The above structure is the basic solution of the present invention. Compared with the prior art, it has at least the following structural difference characteristics and functional advantages: First, a track-type material conveying mechanism is used for the transportation mechanism of the motor housing, which can transport large-sized motor housings more smoothly; second, the tooling has strong compatibility. The track-type material conveying mechanism is a general structure, and the motor housing tooling table provided thereon is replaceable to adapt to motor housings of different model sizes; third, the first optical sensor transceiver module and the optical reflection positioning block cooperate to perform motion positioning, so that the motor housing tooling table is more accurate in its position during the lateral movement, effectively improving the position accuracy and subsequent assembly accuracy; fourth, the CCD vision detection mechanism detects the motor housing in the passing motor housing tooling table. The detected items include but are not limited to whether the motor housing is placed in place and whether there are appearance defects. When unqualified items are detected, they are immediately fed back to the electric control system to discharge defective products; fifth, the automatic assembly of multiple components is realized. Specifically, the motor end cover and the motor shaft are simultaneously assembled onto the motor housing, and the synchronous assembly method effectively improves the product assembly accuracy.

[0010] Preferably, the track-type material conveying mechanism includes a track body, a lead screw disposed in the track body, a track power motor fixed on the track body and drivingly connected to the lead screw, and a plurality of track nut moving blocks drivingly connected to the lead screw. The motor housing tooling table is fixed to the upper end of the track nut moving block.

[0011] In the above preferred solution, the track-type material conveying mechanism adopts the working principle of nut-screw transmission. The track power motor therein is used to convert electrical energy into power to drive the lead screw to rotate relative to the track, and the lead screw is then transmitted to the track nut moving block, so that the track nut moving block and the motor housing tooling table thereon move laterally relative to the lead screw together.

[0012] Further, the motor housing tooling table also has a plurality of housing limiting blocks distributed around the motor support base. The housing limiting blocks have profiling limiting grooves adapted to the motor housing; Both the motor support base and the housing limiting blocks are detachably connected and cooperated with the motor housing tooling table through quick-release rods.

[0013] Through the provision of the housing limit blocks, local limiting and structural support functions can be provided for the motor housing. Multiple housing limit blocks cooperate with each other to provide multi-directional and all-round limiting effects on the circumferential side of the motor housing, so that the motor housing can be more stably located on the motor support base and prevent it from tilting or toppling. On the other hand, through the provision and function of the quick-release rod (holes adapted to the quick-release rod are provided on the motor support base, the housing limit blocks, and the motor housing tooling table), the quick-release and quick-replacement functions of the motor support base and the housing limit blocks can be realized. Based on the above functions, the replaceable assembly function of different specifications of motor support bases, housing limit blocks, and the motor housing tooling table can be realized, so that a single device can meet the assembly functions of different specifications of motor housings and achieve the effect of multi-purpose use of one machine.

[0014] In some specific embodiments of the present invention, the transfer mechanism includes: A first longitudinal drive module, which is configured on the transfer platform, and a first flat plate is drivingly connected to the first longitudinal drive module; A transverse drive module, which is configured on the first flat plate, and a transverse transfer tooling seat plate for supporting the motor end cover is drivingly connected to the transverse drive module; A clamping and picking mechanism, which is longitudinally distributed on both sides of the transverse transfer tooling seat plate; A second longitudinal drive module, which is configured on the first flat plate, and a longitudinal transfer tooling seat plate for supporting the motor end cover is drivingly connected to the second longitudinal drive module, and the longitudinal transfer tooling seat plate is located below the transverse transfer tooling seat plate, and the clamping and picking mechanism is located above the transverse transfer tooling seat plate; A third longitudinal drive module, which is configured on the transfer platform, and a second flat plate and a third flat plate are drivingly connected to the third longitudinal drive module; A first vertical drive module, which is configured on the second flat plate, and a mechanical gripper mechanism is drivingly connected to the first vertical drive module, and the mechanical gripper mechanism is located above the longitudinal transfer tooling seat plate; A fourth longitudinal drive module, which is configured on the transfer platform and in front of the longitudinal transfer tooling seat plate, and a transfer tooling seat plate is drivingly connected to the fourth longitudinal drive module; A second vertical drive module, which is configured on the third flat plate, and a profiling picking mechanism is drivingly connected to the second vertical drive module, and the profiling picking mechanism is located above the transfer tooling seat plate.

[0015] Adopting the transfer mechanism solution with the above structure can realize multi-functional control of the motor end cover. First, the functions of feeding, lateral movement, and longitudinal movement of the motor end cover are realized. Then, the motor end cover is transferred to the transfer tooling seat plate by the mechanical gripper, and then the motor end cover is transferred to the motor housing by the profiling picking mechanism.

[0016] Furthermore, an elevation seat is provided on the first flat plate. The elevation seat has a longitudinally penetrating groove, and the transverse movement tooling seat plate is located on the elevation seat. The longitudinal movement tooling seat plate at least partially penetrates through the longitudinally penetrating groove and can move longitudinally along the longitudinally penetrating groove.

[0017] Through the setting of the elevation seat, structural support is provided to the transverse movement tooling seat plate, and at the same time, the space is divided to meet the installation and operation requirements of the transverse movement tooling seat plate and the longitudinal movement tooling seat plate.

[0019] Through the setting and operation of multiple pairs of photoelectric sensors, first, the position of the motor end cover (located on the transverse movement tooling seat plate or the longitudinal movement tooling seat plate) can be monitored in real time; second, through the position monitoring data of the motor end cover, the positions of the transverse movement tooling seat plate and the longitudinal movement tooling seat plate can be analyzed in real time, so as to accurately monitor and control the movement positions of the transverse movement tooling seat plate and the longitudinal movement tooling seat plate.

[0020] In a preferred embodiment of the present invention, the profiling material taking mechanism includes a support flat plate, a support sleeve fixed to the lower end of the support flat plate, a centering rod penetrating through the support sleeve, a return spring abutted between the centering rod and the support sleeve, and a profiling pressing cylinder fixed to the lower end of the support sleeve; Wherein, at least part of the centering rod extends out of the lower end of the profiling pressing cylinder.

[0021] The support sleeve is provided with a first vertical groove and a second vertical groove; A first feedback rod and a second feedback rod are connected to the centering rod. The first feedback rod extends out of the support sleeve through the first vertical groove, and the second feedback rod extends out of the support sleeve through the second vertical groove; A vertical position sensor adapted to the first feedback rod is provided on the outer wall of the support sleeve; A force sensor is provided on the support flat plate, and the elastic acquisition end of the force sensor abuts against the second feedback rod.

[0023] In a preferred embodiment of the present invention, the pressing shaft mechanism includes a third vertical driving module arranged on the supporting platform, a motor shaft supporting tooling table arranged at the upper end of the third vertical driving module, a shaft-shaped profiling tooling sleeved on the motor shaft supporting tooling table, and a pressing rod driving motor arranged at the lower end of the motor shaft supporting tooling table and used to drive the shaft-shaped profiling tooling.

Start the second longitudinal driving module and adjust the longitudinal position of the longitudinal transfer tooling base plate below the clamping and material-taking mechanism; S26. The clamping and material-taking mechanisms on both sides of the transverse transfer tooling base plate move away from each other to release the motor end cover, and the motor end cover falls onto the longitudinal transfer tooling base plate; S27. Start the second longitudinal driving module and adjust the longitudinal position of the longitudinal transfer tooling base plate below the mechanical gripper mechanism; S28.

Then start the third longitudinal driving module, the second vertical driving module, and the profiling material-taking mechanism respectively to transfer the motor end cover on the intermediate transfer tooling base plate into the motor housing.

[0026] It should be noted that the motor shaft and the motor end cover can be automatically loaded through cooperation with other automated equipment or manually loaded by workers, and no special limitation is made here.

Start the track-type material conveying mechanism to convey the motor housing tooling table, and start the CCD vision inspection mechanism to inspect the motor housing in the passing motor housing tooling table; (Check whether it is placed in place and whether there are appearance defects) S4. When the first optical sensor transceiver module detects the light reflection positioning block, stop running the track-type material conveying mechanism. At this time, the motor housing tooling table is in the specified working position; S5. Start the transfer mechanism to transfer the motor end cover in the transfer mechanism above the motor housing. At the same time, start the pressing shaft mechanism to insert the motor shaft into the motor housing from bottom to top; S6. After the motor end cover and the motor shaft are aligned with each other, the transfer mechanism presses the motor end cover on the upper end of the motor housing, and the pressing shaft mechanism drives the motor shaft close to the motor end cover until the motor shaft is assembled into the motor end cover; S7.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments.

[0043] Referring to Figures 1 to 10 , an intelligent assembly device for a vehicle motor end cover, includes: A working platform 1, on which an electric control system 11 is provided; The orbital material conveying mechanism 2 is transversely spanned on the working platform 1, and a movable motor housing tooling table 21 is arranged on the orbital material conveying mechanism 2; a motor support base 211 and a through hole 212 penetrating through the motor housing tooling table 21 and the motor support base 211 are provided on the motor housing tooling table 21; a first optical sensor transceiver module 22 is arranged on the orbital material conveying mechanism 2, and a light reflection positioning block 213 is arranged on the motor housing tooling table 21. During the lateral movement of the motor housing tooling table 21 relative to the orbital material conveying mechanism 2, the light reflection positioning block 213 moves laterally relative to the optical sensor transceiver module. The CCD vision detection mechanism 3, the first optical sensor transceiver module 22 divides the orbital material conveying mechanism 2 into a feeding section 221 and a discharging section 222, and the CCD vision detection mechanism 3 is located directly above the feeding section 221. The transfer platform 4 is longitudinally arranged at the upper end of the working platform 1, and the transfer platform 4 is located behind the orbital material conveying mechanism 2. The transfer mechanism 5 is arranged on the transfer platform 4, and the transfer mechanism 5 is used to transfer the motor end cover 91 into the motor housing 9 on the motor housing tooling table 21. The support platform 6 is arranged at the lower end of the working platform 1; preferably, a part of the support platform 6 and the transfer platform 4 is an integral platform, that is, the part of the integral platform located above the working platform 1 is the transfer platform 4, and the part located below the working platform 1 is the support platform 6. The pressing mechanism 7 is arranged on the support platform 6, and the transfer mechanism 5 is used to push the motor shaft 92 into the motor housing 9 on the motor housing tooling table 21 and press it together with the motor end cover 91.

[0044] The above structure is the basic solution of the present invention. Compared with the prior art, it has at least the following structural difference features and functional advantages: First, a track-type material conveying mechanism 2 is used as the conveying mechanism for the motor housing 9, which can transport the large-sized motor housing 9 more smoothly; Second, the tooling has strong compatibility. The track-type material conveying mechanism 2 is a general structure, and the motor housing tooling table 21 provided thereon is replaceable to adapt to motor housings 9 of different model sizes; Third, the first optical sensor transceiver module 22 and the optical reflection positioning block 213 cooperate to perform motion positioning, so that the motor housing tooling table 21 is more accurate in its lateral movement, effectively improving the position accuracy and subsequent assembly accuracy; Fourth, the CCD vision detection mechanism 3 detects the motor housing 9 in the passing motor housing tooling table 21. The detection items include but are not limited to whether the motor housing 9 is placed in place and whether there are defects on the appearance. When unqualified items are detected, they are immediately fed back to the electric control system 11 to discharge defective products; Fifth, the automatic assembly of multiple parts is realized. Specifically, the motor end cover 91 and the motor shaft 92 are simultaneously assembled onto the motor housing 9, and the synchronous assembly method effectively improves the product assembly accuracy.

[0045] Preferably, referring to Figures 2 to 4 , the track-type material conveying mechanism 2 includes a track body 23, a lead screw 24 inserted in the track body 23, a track power motor 25 fixed on the track body 23 and drivingly connected to the lead screw 24, and a plurality of track nut moving blocks 26 drivingly connected to the lead screw 24. The motor housing tooling table 21 is fixed to the upper end of the track nut moving block 26.

[0046] In the above preferred solution, the track-type material conveying mechanism 2 adopts the working principle of nut-screw 24 transmission. The track power motor 25 therein is used to convert electrical energy into power to drive the lead screw 24 to rotate relative to the track, and the lead screw 24 is then transmitted to the track nut moving block 26, so that the track nut moving block 26 and the motor housing tooling table 21 thereon move laterally relative to the lead screw 24 together.

[0047] Furthermore, referring to Figures 8 to 9 , a plurality of housing limiting blocks 27 are further distributed on the periphery of the motor support base 211 on the motor housing tooling table 21. The housing limiting blocks 27 have profiling limiting grooves 271 adapted to the motor housing 9; Both the motor support base 211 and the housing limiting blocks 27 form a detachable connection and cooperation with the motor housing tooling table 21 through quick-release rods 272.

[0048] Through the arrangement of the housing limit block 27, a backrest-type position-holding structure is formed, which can provide limit and structural support for a part of the motor housing 9. Multiple housing limit blocks 27 cooperate with each other to provide multi-directional and all-round limit for the circumferential side of the motor housing 9, so that the motor housing 9 is more stably located on the motor support base 211, preventing it from skewing or toppling. On the other hand, through the arrangement and function of the quick-release rod 272 (holes adapted to the quick-release rod 272 are provided on the motor support base 211, the housing limit block 27, and the motor housing tooling table 21), the quick-release and quick-change function of the motor support base 211 and the housing limit block 27 is realized. Based on the above functions, the replaceable assembly function of different specifications of the motor support base 211 and the housing limit block 27 with the motor housing tooling table 21 can be realized, so that a single device can meet the assembly functions of different specifications of the motor housing 9, achieving the effect of multi-purpose use of one machine.

[0050] With the transfer mechanism 5 scheme having the above structure, multifunctional control of the motor end cover 91 can be realized. First, the functions of feeding, lateral movement, and longitudinal movement of the motor end cover 91 are realized.
