Description

Technical Field

[0001] This utility model relates to the technical field of motor controller production equipment, and in particular to an assembly equipment for a brushless DC motor drive controller. Background Technology

[0002] With the continuous innovation of motor control technology, brushless DC motors have been widely used in many fields such as industrial automation, electric vehicles, and smart homes due to their significant advantages such as high efficiency and energy saving, stable operation, and long life.

[0003] Traditional brushless DC motor drive controller assembly methods are mostly manual or assisted by simple semi-automatic equipment. During manual assembly, workers need to manually position, align, and assemble the controller housing and various internal components. This not only requires a high level of skill and concentration from the workers, but also easily leads to fatigue due to prolonged repetitive labor, resulting in operational errors. This can cause uneven stress on the controller housing during assembly, causing the housing to wobble or shift, ultimately leading to misalignment. This significantly affects the assembly accuracy and quality of the product, severely restricting production efficiency and corporate economic benefits. Therefore, we propose an assembly equipment for brushless DC motor drive controllers to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an assembly device for a brushless DC motor drive controller to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembly device for a brushless DC motor drive controller includes: a base plate, on the top of which are four sets of support plates, a fixed platform, and an assembly robot. Synchronous pulleys are rotatably mounted inside the interior of two adjacent sets of support plates, and conveyor belts are driven onto the outer sides of the two sets of synchronous pulleys. A support column and a positioning assembly are mounted on the top of the fixed platform. An industrial camera is mounted on one side of the support column. The positioning assembly includes: an assembly table, a rotating shaft, and four sets of guide seats. A worm gear is rotatably mounted inside the assembly table, and a worm wheel is fixedly mounted on the outer side of the rotating shaft. The top of the rotating shaft is fixed... A turntable is fixedly installed. Each of the four sets of guide seats is hinged to a support rod at the top of the turntable. The four sets of guide seats are slidably installed on the top of the assembly table. Each of the four sets of guide seats has a movable seat fixedly installed on its top. Each of the four sets of movable seats has a clamp fixedly installed on one side. A clamping assembly is provided on the output end of the assembly robot. The clamping assembly includes: a frame, a bidirectional lead screw, and two sets of clamping plates. The bidirectional lead screw is rotatably installed inside the frame. Two sets of movable blocks are threadedly connected to the outer side of the bidirectional lead screw. The two sets of clamping plates are fixedly installed on one side of the corresponding movable blocks.

[0007] Preferably, the bottom of the rotating shaft is rotatably mounted on the bottom inner wall of the assembly table, the two sets of moving blocks are slidably mounted on one side of the frame, a bracket is fixedly mounted on the top of the base plate, a geared motor is fixedly mounted on one side of the bracket, a sector gear is fixedly mounted on the output end of the geared motor, and a transmission gear is fixedly mounted on one side of one set of synchronous pulleys.

[0008] Preferably, the positioning component further includes: a second motor, which is fixedly installed on one side of the assembly table, one end of the worm gear is fixedly installed on the output end of the second motor, the worm wheel meshes with the worm gear, and the worm wheel is disposed inside the assembly table.

[0009] Preferably, the top of the assembly table is provided with four sets of guide grooves, and the four sets of guide seats are slidably installed in the corresponding guide grooves.

[0010] Preferably, the clamping assembly further includes: a motor, which is fixedly mounted on one side of the frame, and one end of the bidirectional lead screw is fixedly mounted on the output end of the motor.

[0011] Preferably, the industrial camera is positioned at the top center of the four sets of clamps, and the sector gear meshes with the transmission gear.

[0012] In this utility model, an assembly device for a brushless DC motor drive controller is provided. A geared motor drives a sector gear to rotate. Since the sector gear meshes with the transmission gear, it causes the transmission gear to rotate intermittently, which in turn drives a set of synchronous pulleys to rotate. Under the transmission action of the synchronous pulleys, the conveyor belt rotates intermittently. Workers place the components of the brushless DC motor drive controller onto the conveyor belt in sequence, thereby transporting the controller housing or components to be assembled to the designated position for subsequent assembly operations. This ensures that each process can be carried out accurately while the components are stationary, reduces operational errors caused by component movement, and improves the stability of the assembly.

[0013] In this utility model, the assembly equipment for a brushless DC motor drive controller uses an industrial camera mounted on one side of a support column to photograph the assembled controller. The image acquisition function is used to obtain the assembly status information of the controller, providing a basis for subsequent quality inspection, so as to determine whether the assembly meets the requirements. It can adapt to the fast-paced operation of the production line and ensure that the inspection process does not become a bottleneck affecting the overall production efficiency.

[0014] This utility model features a rational structural design. By coordinating the rotation of motor two, worm gear, worm wheel, and rotating shaft, the turntable rotates, causing four sets of support rods to pull or push corresponding guide seats into their respective guide grooves. This, in turn, moves the four sets of movable seats closer together or further apart, ultimately synchronizing the movement of the four clamps. This achieves precise clamping and positioning of the controller housing, ensuring its stability during subsequent assembly. Furthermore, the assembly robot moves the clamping components to the component to be grasped. Motor one drives a bidirectional lead screw, causing two sets of movable blocks to slide relative to each other on one side of the frame, thereby... Two sets of clamping plates clamp the components. Then, the assembly robot moves the clamping components above the positioned controller housing and accurately assembles the components into the housing. Through the orderly cooperation of each component, the equipment realizes the automated delivery, positioning, assembly, and preliminary inspection of the brushless DC motor drive controller, improving assembly efficiency and accuracy. This linkage method can accurately clamp and position controller housings of different specifications, effectively avoiding assembly misalignment caused by uneven force or positional wobbling of the housing during the assembly process, significantly improving assembly accuracy, greatly reducing operational errors, and improving assembly precision and consistency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 An assembly device for a brushless DC motor drive controller includes: a base plate 1, with four sets of support plates 2, a fixed platform 8, and an assembly robot 6 arranged on the top of the base plate 1. Synchronous wheels 3 are rotatably mounted inside each pair of adjacent support plates 2, and conveyor belts 4 are driven to the outer sides of the two sets of synchronous wheels 3. A support column 10 and a positioning assembly 9 are arranged on the top of the fixed platform 8. An industrial camera 11 is arranged on one side of the support column 10. The positioning assembly 9 includes: an assembly table 901, a rotating shaft 904, and four sets of guide seats 908. A worm gear 903 is rotatably mounted inside the assembly table 901, a worm wheel 905 is fixedly mounted on the outer side of the rotating shaft 904, and a turntable 906 is fixedly mounted on the top of the rotating shaft 904. Each of the four guide seats 908 is hinged to the top of the turntable 906 with a support rod 907. The four guide seats 908 are slidably installed on the top of the assembly table 901. Each of the four guide seats 908 has a movable seat 909 fixedly installed on its top. Each of the four movable seats 909 has a clamp 910 fixedly installed on one side. The output end of the assembly robot 6 is provided with a clamping assembly 7. The clamping assembly 7 includes: a frame 701, a bidirectional lead screw 703 and two sets of clamping plates 705. The bidirectional lead screw 703 is rotatably installed inside the frame 701. The outer side of the bidirectional lead screw 703 is threadedly connected to two sets of moving blocks 704. The two sets of clamping plates 705 are fixedly installed on one side of the corresponding moving block 704.

[0024] In this embodiment, the bottom of the rotating shaft 904 is rotatably mounted on the bottom inner wall of the assembly table 901, and two sets of moving blocks 704 are slidably mounted on one side of the frame 701. A bracket 5 is fixedly mounted on the top of the base plate 1, and a reduction motor 12 is fixedly mounted on one side of the bracket 5. A sector gear 13 is fixedly mounted on the output end of the reduction motor 12, and a transmission gear 14 is fixedly mounted on one side of one set of synchronous pulleys 3. This avoids the moving blocks 704 from shifting or jamming, and ensures that the clamping plate 705 can stably and accurately clamp the components.

[0025] In this embodiment, the positioning component 9 further includes: a second motor 902, which is fixedly installed on one side of the assembly table 901. One end of the worm gear 903 is fixedly installed on the output end of the second motor 902. A worm wheel 905 meshes with the worm gear 903 and is disposed inside the assembly table 901, thereby achieving precise clamping of the controller housing by the fixture 910.

[0026] In this embodiment, the top of the assembly table 901 is provided with four sets of guide grooves 911, and four sets of guide seats 908 are slidably installed in the corresponding guide grooves 911, which further improves the positioning accuracy of the controller housing and provides a stable foundation for subsequent assembly operations.

[0027] In this embodiment, the clamping assembly 7 further includes a motor 702, which is fixedly installed on one side of the frame 701, and one end of the bidirectional lead screw 703 is fixedly installed on the output end of the motor 702, thereby improving the gripping efficiency of components.

[0028] In this embodiment, the industrial camera 11 is positioned at the top center of the four sets of clamps 910, and the sector gear 13 meshes with the transmission gear 14 to ensure the stability of the production process.

[0029] In this embodiment, during use, the reduction motor 12 is started to drive the sector gear 13 to rotate. Since the sector gear 13 meshes with the transmission gear 14, the transmission gear 14 will rotate intermittently, and drive one of the synchronous pulleys 3 to rotate. Under the transmission action of the synchronous pulleys 3, the conveyor belt 4 will rotate intermittently. Workers will place the components of the brushless DC motor drive controller on the conveyor belt 4 in sequence, thereby transporting the controller housing or components to be assembled to the designated position for subsequent assembly operations.

[0030] The starter motor 902 drives the worm gear 903 to rotate. Since the worm gear 903 meshes with the worm wheel 905, it drives the rotating shaft 904 to rotate, which in turn causes the turntable 906 to rotate. When the turntable 906 rotates, it pulls or pushes the corresponding guide seats 908 through four sets of support rods 907. The four guide seats 908 slide within the guide grooves 911 on the top of the assembly table 901, causing the four moving seats 909 to move closer or further apart, ultimately causing the four clamps 910 to move synchronously. This achieves precise clamping and positioning of the controller housing, ensuring the housing's stable position during subsequent assembly. Then, the assembly robot 6 operates, and its output drives the clamping assembly 7. The robot moves to the component to be gripped and starts motor 702 to drive the bidirectional lead screw 703 to rotate. Since the two sets of moving blocks 704 are threadedly connected to the bidirectional lead screw 703 and slidably installed on one side of the frame 701, the rotation of the bidirectional lead screw 703 will cause the two sets of moving blocks 704 to move closer to each other, driving the two sets of clamping plates 705 to clamp the component. Subsequently, the assembly robot 6 drives the clamping assembly 7 to move above the positioned controller housing and accurately assembles the component into the housing. Through the orderly cooperation of each component, the equipment realizes the automated conveying, positioning, assembly and preliminary inspection of the brushless DC motor driven controller, improving assembly efficiency and accuracy.

[0031] After assembly, the industrial camera 11 on one side of the support column 10 takes a picture of the assembled controller and uses the image acquisition function to obtain the assembly status information of the controller, providing a basis for subsequent quality inspection and determining whether the assembly meets the requirements.
