Description

Technical Field

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

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

[0003] A motor assembly structure is a mechanical device used to assemble the various components of a motor. Its main function is to ensure that the core components of the motor, such as the front cover, rear cover, rotor, and stator, can be installed in a predetermined order. In conventional motor assembly structures, the rear cover of the motor usually relies on mechanical fixtures and positioning mechanisms to complete fixation and positioning. For example, the motor housing is placed in a groove in a mechanical fixture, and 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 method of the motor housing, end cover, and shaft must be comprehensively designed in combination with mechanical strength, coaxiality requirements, sealing performance, and assembly processability.

[0004] Prior art example 1, referring to patent document CN119448705B, discloses a motor end cover assembly assembly device, which includes a turntable assembly and a shell loading assembly, an end cover loading assembly and an assembly assembly arranged in sequence around the turntable assembly, and the motor shell is provided with a motor assembly hole; a shell positioning hole is provided on the turntable assembly; a positioning rotation assembly is installed at a position of the turntable assembly corresponding to the shell positioning hole; the positioning rotation assembly includes a movable part which is arranged on one side of the shell positioning hole and can move in a direction away from or close to the shell positioning hole, the movable part includes a first positioning wheel arranged near the shell positioning hole; the positioning rotation assembly also includes a shell support part arranged below the shell positioning hole, and the shell support part includes a second positioning wheel arranged toward the bottom wall of the motor shell.

[0005] Prior art example 2, referring to patent document CN114012378A, discloses an automatic assembly device for motor end cover seals, including a frame, a U-shaped conveying device arranged on the surface of the frame, a motor assembly jig that can be transmitted to the U-shaped conveying device, a seal loading device, an end cover loading device, an end cover correction device, an end cover rotation and clamping device, and a screw locking device installed on the frame and located on one side of the U-shaped conveying device and arranged in sequence; the present invention sequentially performs seal loading, end cover loading, end cover correction, end cover rotation and clamping, and end cover screw locking.

[0006] In summary, the equipment provided in Technical Example 1 and Technical Example 2 have similar limitations, such as: 1. The function is single and can only realize the installation of the motor end cover and the motor housing, and cannot realize the installation function of other accessories; 2. Its structure is only suitable for micro motors and cannot support the assembly and use of slightly larger motors; 3. The detection method in the equipment is single and cannot achieve high-precision assembly effects; 4. The compatibility of the tooling is poor and cannot be replaced, so the entire equipment is only suitable for the assembly and use of a single motor. Summary of the Invention

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

[0008] The technical solution of the present invention to solve the technical problem is: an intelligent assembly device for a vehicle motor end cover, comprising:

[0009] A working platform on which an electric control system is provided;

[0010] A track-type material conveying mechanism is laterally arranged across a work platform, and is provided with a movable motor housing workbench on the track-type material conveying mechanism; the motor housing workbench has a motor support base and a through hole extending through the motor housing workbench and the motor support base; the track-type material conveying mechanism is provided with a first optical sensor transceiver module, and the motor housing workbench is provided with a light reflection positioning block, and when the motor housing workbench moves laterally relative to the track-type material conveying mechanism, the light reflection positioning block moves laterally relative to the optical sensor transceiver module;

[0011] CCD visual detection mechanism, the first optical sensor transceiver module divides the track-type material conveying mechanism into a feeding section and a discharging section, and the CCD visual detection mechanism is located directly above the feeding section;

[0012] A transfer platform is longitudinally arranged at the upper end of the working platform, and the transfer platform is located at the rear side of the track-type material conveying mechanism;

[0013] A transfer mechanism, which is arranged on the transfer platform and is used to transfer the motor end cover to the motor housing of the motor housing workbench;

[0014] a supporting platform, which is arranged at the lower end of the working platform;

[0015] The shaft pressing mechanism is arranged on the supporting platform and is used to push the motor shaft up into the motor housing of the motor housing tooling table and press it together with the motor end cover.

[0016] The above structure is the basic solution of the present invention. Compared with the existing technology, it has at least the following structural differences and functional advantages: First, the rail-type material conveying mechanism is used as the transportation mechanism for the motor housing, which can transport large-sized motor housings more smoothly; second, the tooling compatibility is strong, the rail-type material conveying mechanism is a universal structure, and the motor housing tooling table arranged thereon is replaceable to adapt to motor housings of different models and sizes; third, the first light sensor transceiver module and the light reflection positioning block cooperate to perform motion positioning, so that the motor housing tooling table can move more accurately during the lateral movement process, effectively improving the position accuracy and subsequent assembly accuracy; fourth, the CCD visual inspection mechanism inspects the motor housing in the motor housing tooling table that passes through, and the inspection items include but are not limited to whether the motor housing is placed in place and whether there are any defects in appearance. When unqualified items are detected, they are fed back to the electronic control system to discharge defective products; fifth, the automated assembly of multiple accessories is realized, specifically, the motor end cover and the motor shaft are assembled to the motor housing at the same time, and the synchronous assembly method effectively improves the product assembly accuracy.

[0017] Preferably, the rail-type material conveying mechanism includes a rail body, a screw passing through the rail body, a rail power motor fixed on the rail body and connected to the screw, and several rail nut moving blocks connected to the screw, and the motor housing workbench is fixed on the upper end of the rail nut moving block.

[0018] In the above preferred scheme, the track-type material conveying mechanism adopts the working principle of nut-screw transmission, in which the track power motor is used to convert electrical energy into power to drive the screw to rotate relative to the track, and the screw is then transmitted to the track nut moving block, so that the track nut moving block and the motor housing workbench above it move laterally relative to the screw.

[0019] Furthermore, the motor housing workbench is further provided with a plurality of housing limit blocks distributed around the motor support base, and the housing limit blocks are provided with contoured limit grooves adapted to the motor housing;

[0020] The motor support base and the housing limit block are both detachably connected to the motor housing workbench via a quick-release rod.

[0021] By setting the housing limit block, it is possible to provide local limiting and structural support for the motor housing. Multiple housing limit blocks work together to provide multi-directional and all-round limiting for the circumference of the motor housing, so that the motor housing can be more stably positioned on the motor support base to prevent it from tilting or tipping over. On the other hand, by setting and using the quick-release rod (holes compatible with the quick-release rod are provided on the motor support base, the housing limit block, and the motor housing workbench), the quick-release and quick-change functions of the motor support base and the housing limit block can be realized. Based on the above functions, the interchangeable assembly function of motor support bases and housing limit blocks of different specifications and the motor housing workbench can be realized, so that a single device can meet the assembly function of motor housings of different specifications, achieving a multi-purpose effect of one machine.

Furthermore, taking the first longitudinal drive module 51 as an example, its specific components preferably include a fixed rail 512, a slider seat 513 slidably mounted on the rail, and a power source (e.g., a drag chain or pneumatic cylinder 59). The specific structural solutions of the other drive modules are similar or identical to the exemplary solution and will not be detailed here.

[0097] Further, refer to Figure 11 The first flat plate 511 is provided with a lifting seat 514, and the lifting seat 514 has a longitudinal through-groove 5141. The transverse tooling seat plate 521 is located on the lifting seat 514, and the longitudinal tooling seat plate 541 is at least partially passed through the longitudinal through-groove 5141 and can realize longitudinal movement along the longitudinal through-groove 5141.

[0098] By setting up the lifting seat 514, structural support is provided to the transverse tooling seat plate 521, and at the same time, the space is divided to meet the installation and operation requirements of the transverse tooling seat plate 521 and the longitudinal tooling seat plate 541.

[0099] Optionally, refer to Figure 12 A first through-beam sensor 5211, a second through-beam sensor 5212 and a third through-beam sensor 5213 are laterally arranged on the upper edges of the front and rear sides of the first flat plate 511;

[0102] Through the setting and operation of multiple beamforming sensors, firstly, the position of the motor end cover 91 (located on the transverse tooling seat plate 521 or the longitudinal tooling seat plate 541) can be monitored in real time; secondly, through the position monitoring data of the motor end cover 91, the positions of the transverse tooling seat plate 521 and the longitudinal tooling seat plate 541 can be analyzed in real time, thereby accurately monitoring and controlling the movement of the transverse tooling seat plate 521 and the longitudinal tooling seat plate 541.

[0103] Example 3

[0104] Reference Figures 6 to 8 In a preferred embodiment of the present invention, the profiling material taking mechanism 8 includes a supporting plate 81, a supporting sleeve 82 fixed to the lower end of the supporting plate 81, a centering rod 83 passing through the supporting sleeve 82, a return spring 84 abutting between the centering rod 83 and the supporting sleeve 82, and a profiling pressing cylinder 85 fixed to the lower end of the supporting sleeve 82;

[0105] The core fixing rod 83 at least partially extends out from the lower end of the contour pressing cylinder 85 .

[0106] The support sleeve 82 is provided with a first vertical groove 822 and a second vertical groove 823;

[0107] The centering rod 83 is connected to a first feedback rod 831 and a second feedback rod 832. The first feedback rod 831 extends out of the support sleeve 82 through the first vertical slot 822, and the second feedback rod 832 extends out of the support sleeve 82 through the second vertical slot 823.

[0108] A vertical position sensor 821 adapted to the first feedback rod 831 is provided on the outer wall of the support sleeve 82;

[0109] A force sensor 811 is provided on the support plate 81 , and an elastic collecting end portion 8111 of the force sensor 811 abuts against the second feedback rod 832 .

[0110] The structural scheme of the above-mentioned contour-fetching mechanism 8 is adopted, and the support plate 81 and the support sleeve 82 are used to provide installation space and structural support for other components; the contour-fetching cylinder 85 is adapted to the shape of the motor end cover 91 and is used to remove the motor end cover 91; the centering rod 83 is adapted to the shape of the motor shaft 92 and is used to press the motor end cover 91 onto the motor housing 9 (in this process, the centering rod 83 is stressed and forces the return spring 84 to contract); when the contour-fetching mechanism 8 is separated from the motor end cover 91, the centering rod 83 is released, and the return spring 84 acts on the centering rod 83 to realize the centering rod 83 Reset function; through the coordinated cooperation of the vertical position sensor 821 and the first feedback rod 831, the movement stroke of the centering rod 83 can be accurately controlled to maintain a high installation accuracy; through the coordinated cooperation of the force sensor 811 and the second feedback rod 832, it can ensure that the force is consistent each time the press is installed (the principle is similar to the need to maintain the same torque when screwing in a precision structure), which can ensure assembly accuracy and position accuracy, avoid damage to components and stress concentration, and ensure connection reliability and sealing, thereby improving motor performance and operating stability, and improving component life and reliability.

[0111] Preferably, the contoured pressing cylinder 85 has an insertion block 851, and the motor end cover 91 has a slot 911. The insertion block 851 can be inserted into the slot 911 to facilitate insertion and removal of the motor end cover 91. Furthermore, the contoured pressing cylinder 85 is connected to an air pump (standard components, not shown) via an air pipe. When the air pump is activated, it releases air, creating a negative pressure effect between the contoured pressing cylinder 85 and the motor end cover 91, thereby preventing the motor end cover 91 from separating from the contoured material retrieving mechanism 8. When the motor end cover 91 is in place, the air pump is turned off to eliminate the negative pressure effect, allowing the motor end cover 91 to leave the contoured material retrieving mechanism 8. Furthermore, the motor end cover 91 has a raised structure 912, and the contoured pressing cylinder 85 has an escape groove 852 that matches the raised structure 912.
