Description

Technical Field

[0001] This application relates to the field of motor manufacturing technology, and in particular to a rubber ring device and control method for heat dissipation during motor rotor mounting. Background Technology

[0002] During the production and assembly of motor rotors, sealing and heat-dissipating rubber rings are typically installed at both ends of the rotor shaft. These rings serve to reduce heat dissipation costs, provide sealing, cushioning, and limit movement. Currently, the installation of these rubber rings is mostly done manually. Operators must first spread the rubber rings open and then insert them into the corresponding positions on the rotor shaft. This is not only labor-intensive and inefficient, but manual installation is also prone to problems such as misalignment or improper installation, affecting the effectiveness of the rubber rings and making it difficult to adapt to the needs of mass automated production. Some existing automated equipment for installing rubber rings exists, but due to potential differences in the feeding speed of the rubber rings on both sides, situations can arise where one end of the rubber ring has reached the pressing position while the other end has not, yet the pressing process continues, resulting in the missing or improperly pressed rubber ring on that end. If manual intervention or sequential pressing is used, production efficiency and product yield will be affected. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a device for installing heat-dissipating rubber rings on motor rotors, which can perform synchronous pressing after the heat-dissipating rubber rings at both ends are in place, avoiding the problem of missing installations and effectively improving product yield and production efficiency.

[0004] This application also provides a control method for a heat dissipation device for mounting a rubber ring on a motor rotor.

[0005] The heat dissipation device for mounting a motor rotor according to the first aspect of this application includes: The machine base is equipped with clamps for holding the rotor; A rotor feeding mechanism is disposed on one side of the fixture, and the rotor feeding mechanism is used to transport the rotor to the fixture; A heat dissipation rubber ring feeding mechanism is used to provide heat dissipation rubber rings. At least one set of the heat dissipation rubber ring feeding mechanism is provided. The heat dissipation rubber ring feeding mechanism includes a vibrating plate and a first air blowing pipe. The discharge port of the vibrating plate is connected to a discharge track. The first air blowing pipe is provided at the discharge port of the vibrating plate. The first air blowing pipe is used to blow the heat dissipation rubber ring into the discharge track. The first air blowing pipe is provided with a first valve. Two sets of pressing mechanisms are respectively disposed at both ends of the clamp along the rotor axis. The two sets of pressing mechanisms are respectively connected to the discharge track. Each set of pressing mechanisms includes a pressing base, a second air blowing pipe, a first baffle and a pressing rod. The pressing base is vertically provided with a feeding channel, which is connected to the discharge track. A pressing position is provided at the bottom of the feeding channel. The second air blowing pipe is disposed at the top of the feeding channel and is provided with a second valve. The first baffle is movably disposed in the middle of the feeding channel. The first baffle can open the feeding channel under the action of the airflow of the second air blowing pipe and reset after the second air blowing pipe is closed. The pressing rod is disposed on the side of the pressing position away from the clamp. The pressing rod is connected to a pressing drive component. The pressing drive component is used to drive the pressing rod to move to press the heat dissipation rubber ring on the pressing position toward the rotor. The control mechanism includes sensors and a controller. Each first baffle is equipped with a corresponding sensor, which detects whether the heat-dissipating rubber ring is present on the first baffle. The controller is connected to the sensors, the first valve, the second valve, the vibratory feeder, and the press-fitting drive. The control mechanism is configured to: when both sets of sensors detect the heat-dissipating rubber ring on the first baffle, control the two second valves to open the corresponding second air pipes; after opening the second air pipes and after a preset delay time, control the press-fitting drive to drive the press-fitting rod for press-fitting, and control the second valves to close the second air pipes; when any sensor does not detect the heat-dissipating rubber ring on the first baffle, control the vibratory feeder to start, and control the first valve to open the first air pipe to replenish the heat-dissipating rubber ring to the first baffle.

[0006] The device for installing heat dissipation rubber rings on a motor rotor according to the first aspect of this application has at least the following advantages: By setting two sets of pressing mechanisms corresponding to both ends of the rotor, and equipping each first baffle with a sensor to detect the position of the heat dissipation rubber ring, the subsequent pressing action will only be started when both first baffles detect that the heat dissipation rubber ring is in place. This effectively avoids the problem of missing installation caused by inconsistent feeding speeds on both sides, ensuring that the installation of heat dissipation rubber rings at both ends can be completed simultaneously with each pressing. This improves the production yield and eliminates the need for additional manual intervention, making it suitable for batch automated production. The first baffle receives the heat dissipation rubber rings sent from the discharge track, and the airflow from the second air pipe opens the first baffle to allow the heat dissipation rubber rings to fall into the pressing position. Combined with the automatic reset structure of the first baffle, the overall structure is simple and reliable, and can stably complete the conveying and transfer of heat dissipation rubber rings, reducing the probability of material jamming.

[0007] According to the first aspect of the present application, the motor rotor mounting heat dissipation device includes a clamping fixture comprising a base and two pressure blocks. The base supports the rotor, and the two pressure blocks are slidably disposed on both sides of the base along the circumference of the rotor. The pressure blocks can slide relative to each other to clamp the rotor.

[0008] According to the first aspect of the present application, the motor rotor mounting heat dissipation device is provided with a rubber ring, wherein the first baffle is rotatably disposed in the feed channel via a first rotating shaft, and the first rotating shaft is provided with a first torsion spring.

[0009] According to the first aspect of the present application, the motor rotor mounting heat dissipation rubber ring device has a second baffle movably provided on the side of the press-fit position near the clamp, and the second baffle can open the press-fit position under the pressure of the press-fit rod.

[0010] According to the first aspect of the present application, the motor rotor mounting heat dissipation device has a second baffle rotatably mounted on the press-fitting seat via a second rotating shaft, and the second rotating shaft is provided with a second torsion spring.

[0011] According to the first aspect of the present application, the motor rotor mounting heat dissipation rubber ring device includes a rod body and a rod head. The rod body is provided with a through hole, the rod head is slidably disposed in the through hole and its end can extend out of the through hole, a spring is provided between the rod head and the through hole, the outer diameter of the rod head is adapted to the inner diameter of the heat dissipation rubber ring, and the inner diameter of the through hole is adapted to the outer diameter of the rotor shaft.

[0012] According to the embodiment of the first aspect of this application, the device for installing heat dissipation rubber rings on motor rotors includes two sets of heat dissipation rubber ring feeding mechanisms, which are respectively configured to correspond to two sets of pressing mechanisms.

[0013] According to the first aspect of the present application, the motor rotor mounting heat dissipation device includes a rotor feeding mechanism comprising a feeding track, the feeding track being inclined downward toward one end of the clamp, and the discharge end of the feeding track corresponding to the clamp, so as to feed the rotor from the feeding track to the clamp.

[0014] According to the first aspect of the present application, the motor rotor mounting heat dissipation rubber ring device further includes a rotor feeding mechanism, which is disposed at the feeding end of the feeding track and is used to pick up the rotor and transport it to the feeding track.

[0015] The control method for the heat dissipation device for mounting a motor rotor according to the second aspect embodiment of this application is applied to the heat dissipation device for mounting a motor rotor according to the first aspect embodiment of this application. The control method includes: Acquire the first signals output by the two sets of sensors, and determine whether two sets of the first signals indicating the presence of heat dissipation rubber rings on the first baffle are received simultaneously; When two sets of the first signals are received simultaneously, the two second valves are controlled to open the corresponding second air pipes, so that the second air pipes blow air at the same time. The airflow opens the first baffle, so that the heat dissipation rubber ring falls from the first baffle into the press-fit position. After the second air blowing pipe starts blowing air, a timer is started. When the preset delay time is reached, the second valve is controlled to close the second air blowing pipe, so that the first baffle is reset. Then, the pressing drive is controlled to drive the pressing rod to move, so as to press the heat dissipation rubber ring on the pressing position synchronously towards both ends of the rotor. When any of the sensors detects that the corresponding first baffle does not have a heat dissipation rubber ring, the vibratory feeder is activated and the first valve opens the first air pipe to replenish the heat dissipation rubber ring to the corresponding first baffle.

[0016] The motor rotor mounting heat dissipation rubber ring device according to the second aspect embodiment of this application has at least the following beneficial effects: by first detecting the position of the heat dissipation rubber rings on the first baffles at both ends, the pressing is only started after both ends are in place, which can effectively avoid the problem of missing installation caused by the heat dissipation rubber rings on one side not being in place. Synchronous pressing also improves the efficiency of pressing operation. With the automated heat dissipation rubber ring replenishment process, no manual intervention is required, which can be adapted to long-term batch automated production, effectively improving production efficiency and product yield.

[0024] Reference Figures 1 to 10The first aspect of this application provides a device for mounting heat dissipation rubber rings on motor rotors, including a base 100, a rotor feeding mechanism 200, a heat dissipation rubber ring feeding mechanism 300, a pressing mechanism 400, and a control mechanism 500.

[0025] Reference Figures 3 to 5 The base 100 is equipped with a clamp 110 for clamping the rotor. Specifically, the clamp 110 includes a base 120 and two pressure blocks 130. The base 120 supports the rotor, and the two pressure blocks 130 are slidably disposed on both sides of the base 120 along the circumference of the rotor. The pressure blocks 130 can slide relative to each other to clamp the rotor, ensuring the stability of the rotor position during the pressing process of the heat dissipation rubber ring and preventing displacement, thus improving the pressing accuracy of the heat dissipation rubber ring. The pressure blocks 130 are provided with an arc surface adapted to the rotor body, which increases the contact area between the pressure blocks 130 and the rotor, ensuring clamping stability and preventing damage to the rotor surface.

[0026] Furthermore, the two pressure blocks 130 are driven by two independent single-rod cylinders 140. The two single-rod cylinders 140 simultaneously drive the two pressure blocks 130 to slide relative to each other and move closer together, thus cooperating with the base 120 to clamp the rotor. The clamping action is stable and reliable, with a fast response speed, and can adapt to the cycle time requirements of automated production. Alternatively, the two pressure blocks 130 can also be driven directly by a double-rod cylinder. The two pressure blocks 130 are respectively connected to the two piston rods of the double-rod cylinder, thus synchronously driving the two pressure blocks 130 to move relative to each other, achieving the same clamping and fixing of the rotor.

[0027] It should be noted that the base 120 can also be provided with a positioning groove. The positioning groove is used to accommodate the rotor. After the rotor is placed in the positioning groove, it is clamped by the pressure blocks 130 on both sides, which can achieve initial positioning of the rotor and avoid rotor position displacement during clamping, further improving the clamping accuracy and stability. The groove wall of the positioning groove can also be set as an arc surface that fits the rotor body, so that the rotor is placed more stably and cooperates better with the pressure blocks 130 to fix the rotor.

[0028] Reference Figures 1 to 5The rotor loading mechanism 200 is located on one side of the fixture 110 and is used to automatically transport the rotor to the base 120 of the fixture 110, replacing manual loading and improving processing efficiency. Specifically, the rotor loading mechanism 200 includes a loading track 210, which is inclined downwards at one end facing the fixture 110. During operation, the rotor is placed on the feed end of the loading track 210 and rolls or slides downwards along the track under the action of gravity until it falls directly into the fixture 110 from the discharge end of the loading track 210, completing the rotor loading. It should be noted that the loading track 210 can also be set horizontally. In this case, a conveyor belt for driving the rotor can be installed inside the loading track 210, which can also realize the automatic transport of the rotor. The specific setting of the loading track 210 for transporting the rotor can be selected according to the actual production site layout.

[0029] Furthermore, a guide structure is provided at the end of the feeding track 210. The guide mechanism corresponds to the base 120, allowing the rotor to reach the clamp 110 under the guidance of the guide structure, eliminating the need for an additional gripping and transfer structure, further simplifying the overall structure of the equipment and reducing production costs. The guide structure includes a connecting plate 220 and a guide plate 230. The connecting plate 220 is located at the bottom of the discharge end of the feeding track 210 and corresponds to the base 120, serving as a receiving platform for the rotor. The guide plate 230 is located above the discharge end of the feeding track 210. The guide plate 230 extends in an arc or slope shape, with its starting end smoothly transitioning to or adjacent to the end of the feeding track 210. The end of the guide plate 230 extends directly above the connecting plate 220 to limit the rotor's movement trajectory when it leaves the feeding track 210, ensuring the rotor lands stably on the connecting plate 220. During operation, after the rotor moves downward along the feeding track 210, it will fall onto the connecting plate 220 along the guide track under the limit of the guide plate 230. Then, under the action of the pressure block 130, the rotor is clamped onto the base 120, thus completing the automatic feeding of the rotor. The structure is simple, the operation is convenient, and the work efficiency is improved.

[0030] It should be noted that the rotor on the feeding track 210 can also be conveyed to the fixture 110 by a gripping robot. In this case, the gripping robot is positioned between the feeding track 210 and the fixture 110 to grab the rotor that has been conveyed to the designated position from the discharge track 320 and move it onto the base 120 of the fixture 110, thereby completing the automatic feeding of the rotor without manual loading and unloading, which is suitable for automated continuous production. Furthermore, the discharge end of the feeding track 210 is provided with a limit plate, which abuts against the shafts at both ends of the rotor, thereby limiting the rotor that has slid down to the designated position, facilitating the gripping robot's gripping and positioning, and preventing the rotor from sliding down excessively and affecting the picking accuracy. It should be noted that the gripping robot adopts the structure of an existing robot, which will not be described in detail in this application. Those skilled in the art can reasonably select one based on existing technology.

[0031] In some other embodiments of this application, the rotor feeding mechanism 200 further includes a picking robot 240, which is disposed at the feeding end of the feeding track 210. The picking robot 240 is used to pick up rotors from the rotor stockpile to be processed and place the rotors sequentially onto the feeding track 210, thereby realizing fully automatic continuous feeding of rotors, further reducing manual intervention and improving the automation level of production. Of course, the feeding end of the feeding track 210 can also be directly connected to the discharge mechanism of the previous process to realize continuous automated operation of the entire production line.

[0032] Reference Figures 3 to 5 In some embodiments of this application, the device for mounting heat dissipation rubber rings on motor rotors further includes a feeding mechanism 600 for automatically feeding the rotor from the fixture 110. Specifically, the feeding mechanism 600 includes a feeding track, which is disposed below the machine base 100 and inclined downward toward the discharge end of the feeding track to receive the rotor output from the fixture 110 and complete the feeding of the rotor.

[0033] In this embodiment, the base 120 is jacked up and positioned on the machine base 100 at the feeding end of the unloading track, and a lifting cylinder 150 is connected to the base 120. When unloading is required, the lifting cylinder 150 drives the base 120 to descend, causing the base 120 to fall onto the unloading track. At this time, the two end shafts of the rotor on the base 120 are positioned on both sides of the unloading track, allowing the rotor to automatically slide down the unloading track to complete the unloading process. This eliminates the need for an additional unloading gripping structure, further simplifying the overall structure of the equipment, reducing manufacturing costs, and simplifying the control logic. After unloading is complete, the lifting cylinder 150 drives the base 120 to rise and reset, awaiting the next rotor feeding and clamping. The structure is simple and practical, meeting the unloading requirements of automated production.

[0034] Reference Figure 1 , Figure 2 and Figure 6 The heat dissipation rubber ring feeding mechanism 300 is used to provide heat dissipation rubber rings to be press-fitted. In this embodiment, since heat dissipation rubber rings need to be installed at both ends of the rotor, two sets of heat dissipation rubber ring feeding mechanisms 300 are correspondingly provided, supplying heat dissipation rubber rings to the pressing mechanisms 400 at both ends respectively. This ensures that the feeding on both sides does not interfere with each other, and that materials can be replenished according to the actual needs of both sides, avoiding feeding chaos. Of course, according to production needs, only one set of heat dissipation rubber ring feeding mechanism 300 can be set up to supply materials to the pressing mechanisms 400 on both sides simultaneously, which can reduce the number of equipment components and reduce the overall cost of the equipment.

[0035] It was a terrible loss. Figure 6Specifically, each set of heat dissipation rubber ring feeding mechanism 300 includes a vibratory feeder 310 and a first air blowing pipe 330. The vibratory feeder 310 is provided with a discharge port, which is connected to a discharge track 320. The first air blowing pipe 330 is located at the discharge port of the vibratory feeder 310. The vibratory feeder 310 automatically sorts and organizes the scattered heat dissipation rubber rings and moves them towards the discharge port. Then, airflow is sprayed through the first air blowing pipe 330 to quickly blow the heat dissipation rubber rings at the discharge port into the discharge track 320. Further, the first air blowing pipe 330 is provided with a first valve 340. When it is necessary to send the heat dissipation rubber rings at the discharge port into the discharge track 320, the first valve 340 opens the first air blowing pipe 330, causing the first air blowing pipe 330 to blow air, thereby blowing the heat dissipation rubber rings into the discharge track 320. When the delivery of heat dissipation rubber rings is not required, the first valve 340 closes the first air pipe 330, thereby reducing the consumption of compressed air and reducing production costs.

[0036] Reference Figure 1 , Figure 2 and Figure 6 The pressing mechanism 400 is used to press the heat dissipation rubber rings onto the preset installation positions of the rotor. There are two sets of pressing mechanisms 400, located at both ends of the clamp 110 along the rotor axis. The two sets of pressing mechanisms 400 are independent and connected to the discharge track 320 of the corresponding heat dissipation rubber ring feeding mechanism 300. This allows for the simultaneous pressing of heat dissipation rubber rings at both ends of the rotor, improving processing efficiency.

[0037] Reference Figures 7 to 10 Specifically, each pressing mechanism 400 includes a pressing base 410, a second air blowing pipe 420, a first baffle 430, and a pressing rod 440. The pressing base 410 has a vertically arranged feeding channel 411, the upper end of which connects to the discharge track 320 of the heat dissipation rubber ring feeding mechanism 300, allowing the heat dissipation rubber ring to directly enter the vertical feeding channel 411 after exiting the discharge track 320 and move downwards along the feeding channel 411. A pressing position 412 is provided at the bottom of the feeding channel 411 for temporarily storing the heat dissipation rubber ring to be pressed.

[0038] The second air blowing pipe 420 is located at the top of the feed channel 411 and can spray airflow into the feed channel 411. The second air blowing pipe 420 is equipped with a second valve 421, which controls the on / off of the air blowing through the second air blowing pipe 420. The airflow can be turned on or off as needed, reducing compressed air waste and lowering production costs.

[0039] The first baffle 430 is movably disposed in the middle of the feed channel 411. In its natural state, the first baffle 430 blocks the feed channel 411 and can catch the heat-dissipating rubber ring falling from the upper feed channel 411, so that the heat-dissipating rubber ring is temporarily stored on the first baffle 430. The first baffle 430 can open the feed channel 411 under the airflow of the second air pipe 420, so that the heat-dissipating rubber ring on the first baffle 430 falls into the lower pressing position 412, and can be reset after the second air pipe 420 is closed.

[0040] Specifically, the first baffle 430 is rotatably mounted on the feed channel 411 via a first rotating shaft, which is equipped with a first torsion spring. The torque of the first torsion spring is less than the thrust of the airflow from the second air-blowing pipe 420. When the second air-blowing pipe 420 blows air, the downward thrust of the airflow overcomes the torque of the first torsion spring, pushing the first baffle 430 downward to open the feed channel 411. This allows the heat-dissipating rubber ring temporarily stored on the first baffle 430 to fall into the lower pressing position 412, completing the feeding of the heat-dissipating rubber ring. When the second valve 421 closes the second air-blowing pipe 420 to stop blowing air, the first baffle 430 automatically resets under the torque of the first torsion spring, ready to receive the next heat-dissipating rubber ring. The structure is simple, the response speed is fast, and the material blocking and discharging actions can be completed without additional drive components, making control convenient and the cost lower.

[0041] A pressing rod 440 is located on the side of the pressing position 412 away from the clamp 110, and a pressing drive component 441 is connected to the pressing rod 440. The pressing position 412 has an opening on the side facing the clamp 110. When the pressing drive component 441 drives the pressing rod 440 to move towards the clamp 110, the pressing rod 440 causes the heat-dissipating rubber ring to extend out of the opening from the pressing seat 410 and move along the rotor's axial direction, pressing against the rotor, thereby completing the pressing operation of the heat-dissipating rubber ring. The pressing drive component 441 is a pressing cylinder, which has a simple structure and stable operation.

[0042] It is conceivable that the opening is equipped with a second baffle 413. The second baffle 413 can open under the push of the pressing rod 440 to allow the heat dissipation rubber ring to pass through, and can reset to close the opening when the pressing rod 440 returns. By providing the second baffle 413, the heat dissipation rubber ring in the pressing position 412 can be blocked, preventing the heat dissipation rubber ring from accidentally sliding out of the opening when no pressing operation is performed, thus ensuring the accuracy of feeding. Specifically, the second baffle 413 is rotatably set at the opening via a second rotating shaft, and the second rotating shaft is equipped with a second torsion spring. In the natural state, the second torsion spring drives the second baffle 413 to keep the opening closed. When the pressing rod 440 pushes the heat dissipation rubber ring to move towards the opening, the heat dissipation rubber ring can overcome the torque of the second torsion spring and push the second baffle 413 open to extend out of the pressing seat 410. After pressing is completed, the pressing rod 440 retracts, and the second baffle 413 automatically resets to close the opening again under the action of the second torsion spring. The structure is simple and reliable, requires no additional drive, is easy to control, and has a lower cost.

[0043] In this embodiment, the second baffle 413 is configured as a double-door structure. The two door panels are respectively rotatably mounted on both sides of the opening via the second rotating shaft. When the pressing rod 440 pushes the heat dissipation rubber ring forward, the heat dissipation rubber ring can push open the two door panels and extend out of the opening to complete the pressing. After the pressing is completed, the pressing rod 440 retracts, and the two door panels automatically reset and close under the action of the second torsion spring. The structure is simple and reliable, and automatic opening and closing can be achieved without additional drive.

[0044] Reference Figure 8 The press rod 440 includes a rod body 442 and a rod head 443. The rod body 442 is provided with a through hole. The rod head 443 is slidably disposed in the through hole and its end can extend out of the through hole. A spring 444 is provided between the rod head 443 and the through hole. The outer diameter of the rod head 443 is adapted to the inner diameter of the heat dissipation rubber ring. The inner diameter of the through hole is adapted to the outer diameter of the rotor shaft. During the press-fitting operation, the rod head 443 first inserts into the inner diameter of the heat-dissipating rubber ring in the press-fitting position 412 to position the heat-dissipating rubber ring. Then, it moves the heat-dissipating rubber ring towards the rotor, preventing it from shifting or falling off during the press-fitting process and ensuring the accurate positioning of the press-fitting position 412. After the rod head 443 aligns with the rotor shaft, it retracts along the through hole during the continued movement of the press-fitting rod 440. The rod body 442 pushes out the heat-dissipating rubber ring positioned on the rod head 443, fitting it onto the rotor shaft and pushing it to the preset installation position. The rotor shaft then passes through the through hole of the rod body 442, without obstructing the press-fitting stroke. The press-fitting action is smooth and continuous with high positioning accuracy. After press-fitting is completed, the press-fitting drive component 441 drives the press-fitting rod 440 back away from the rotor, and the rod head 443 resets under the action of the spring 444, ready for the next press-fitting operation.

[0045] Reference Figure 1 and Figure 2The control mechanism 500 is electrically connected to the rotor feeding mechanism 200, the heat dissipation rubber ring feeding mechanism 300, and the pressing mechanism 400, respectively. It can control the action of each component, realize the automated operation of the whole process, eliminate the need for manual operation, reduce labor costs, and improve production stability.

[0046] Reference Figure 1 , Figure 2 , Figures 6 to 10 Furthermore, the control mechanism 500 includes a sensor 510 and a controller. The sensor 510 is disposed on the pressing base 410 and corresponds to the first baffle 430. The sensor 510 is used to detect whether there is a heat dissipation rubber ring on the first baffle 430. The controller is connected to the sensor 510, the first valve 340, the second valve 421, the vibratory plate 310, and the pressing drive component 441. When the sensor 510 detects a heat dissipation rubber ring on the first baffle 430, the controller controls the corresponding first valve 340 to close the first air pipe 330, preventing excess heat dissipation rubber rings from continuously being fed into the feeding channel 411 from the discharge track 320 and causing blockage. When both sets of sensors 510 detect a heat-dissipating rubber ring on the first baffle 430, the controller controls the second valve 421 to open the second air blowing pipe 420, causing the second air blowing pipe 420 to blow air into the feed channel 411. At this time, the first baffle 430 opens the feed channel 411 under the thrust of the airflow, causing the heat-dissipating rubber ring on the first baffle 430 to fall into the pressing position 412. After the two sets of second air blowing pipes 420 start blowing air and after a preset delay time, the controller controls the pressing drive 441 to drive the pressing rod 440 to move towards the rotor, so as to press the heat-dissipating rubber ring against the rotor to complete the pressing. The controller then controls the second valve 421 to close the second air blowing pipe 420, and the first baffle 430 resets to wait for the next batch of heat-dissipating rubber rings. When any set of sensors 510 does not detect a heat dissipation rubber ring on the first baffle 430, the controller controls the corresponding vibratory plate 310 to start and the first valve 340 to open the first air pipe 330, so that the heat dissipation rubber ring is replenished on the first baffle 430, in preparation for the next round of pressing of the heat dissipation rubber ring.

[0047] It should be noted that the rotor can also be transported from the fixture 110 to the unloading track by a unloading robot, which can also achieve automatic unloading. The specific choice can be flexibly made according to actual production needs and equipment layout, and this application does not impose strict restrictions on this. Furthermore, the unloading robot can be integrated with the clamping robot on the same moving module, that is, one moving module is equipped with two grippers. In this case, the rotor on the loading track 210 can be transported to the fixture 110, and the rotor on the fixture 110 can also be transported to the unloading track. This reduces the number of moving modules, reduces the equipment footprint, lowers equipment production costs, and simplifies the control logic.

[0048] The working process of the heat dissipation rubber ring installation equipment for motor rotors described in the first aspect of this application is as follows: First, the material handling robot 240 picks up the rotors from the rotor material pile to be processed and places them sequentially onto the feeding track 210; the rotors automatically slide down the feeding track 210 to the discharge end of the feeding track 210 and enter the positioning groove of the base 120 under the guidance of the guide structure; then, the two pressure blocks 130 slide relative to each other to come closer together, thereby cooperating with the base 120 to complete the clamping and fixing of the rotor; subsequently, the two sets of heat dissipation rubber ring feeding mechanisms 300 operate respectively, and the vibrating plate 310 sorts the scattered heat dissipation rubber rings and sends them to the discharge end. The feed inlet opens the first air pipe 330 through the first valve 340, blowing the heat-dissipating rubber ring into the discharge track 320. The heat-dissipating rubber ring enters the first baffle 430 of the feed channel 411 along the discharge track 320. When the sensor 510 detects the presence of the heat-dissipating rubber ring on the first baffle 430, the controller controls the corresponding first valve 340 to close the first air pipe 330. When both sets of sensors 510 detect the presence of the heat-dissipating rubber ring on the first baffle 430, the controller controls the two second valves 421 to open the second air pipes 420, causing the first baffle 430 to open the feed channel 411 under the push of the airflow. The heat dissipation rubber ring on the 30 falls into the lower pressing position 412; after the two sets of second air blowing pipes 420 start blowing air and after a preset delay time, the controller controls the two pressing drive components 441 to drive the pressing rods 440 on both sides to move towards the rotor. The rod head 443 of the pressing rod 440 first inserts into the inner diameter of the heat dissipation rubber ring for positioning, and drives the heat dissipation rubber ring to push open the second baffle 413 and move towards the rotor. After the rod head 443 aligns with the rotor shaft, it retracts, and the rod body 442 pushes the heat dissipation rubber ring out, fits it onto the shaft, and pushes it to the preset installation position, completing the synchronous pressing of the heat dissipation rubber rings at both ends. At the same time, the controller controls the second valve 421 to close the second air blowing. The tube 420 is used to reset the first baffle 430; when any set of sensors 510 detects that there is no heat dissipation rubber ring on the first baffle 430, the controller controls the corresponding vibratory plate 310 to start and the first valve 340 to open the first air blowing pipe 330 to replenish the heat dissipation rubber ring to the first baffle 430 in preparation for the next round of pressing; after pressing is completed, the pressing rod 440 retracts, and the second baffle 413 automatically resets and closes the opening; then the pressing block 130 releases the rotor, the base 120 descends, so that the rotor that has completed pressing falls into the unloading track and automatically slides out along the unloading track to complete the unloading, and finally the base 120 rises and resets, waiting for the next round of processing.

[0049] The device for installing heat dissipation rubber rings on motor rotors according to the first aspect of this application, by setting two sets of pressing mechanisms 400 corresponding to both ends of the rotor, and equipping each first baffle 430 with a sensor 510 to detect the position of the heat dissipation rubber ring, the subsequent pressing action will only be initiated when both first baffles 430 detect that the heat dissipation rubber ring is in place. This can effectively avoid the problem of missing installation caused by inconsistent feeding speeds on both sides, and ensure that the installation of heat dissipation rubber rings at both ends can be completed simultaneously in each pressing. This improves the production yield and does not require additional manual intervention, making it suitable for batch automated production. The first baffle 430 receives the heat dissipation rubber ring sent from the discharge track 320, and the airflow from the second air pipe 420 opens the first baffle 430 to allow the heat dissipation rubber ring to fall into the pressing position 412. With the automatic reset structure of the first baffle 430, the overall structure is simple and reliable, and can stably complete the conveying and transfer of heat dissipation rubber rings, reducing the probability of material jamming failure.

[0050] Reference Figure 11 The second aspect of this application provides a control method for the heat dissipation device for mounting a motor rotor described above, which is applied to the heat dissipation device for mounting a motor rotor described in the first aspect of this application. The control method includes, but is not limited to, steps S100, S200, S300 and S400.

[0051] Step S100: Obtain the first signals output by the two sets of sensors 510, and determine whether two sets of first signals indicating the presence of heat dissipation rubber rings on the first baffle 430 are received simultaneously.

[0052] Specifically, the controller acquires the detection signals of the corresponding sensors 510 set on the two press-fit seats 410 respectively. The sensors 510 detect in real time whether the corresponding first baffle 430 temporarily stores a heat dissipation rubber ring, and convert the detection result into a first signal and send it to the controller. The controller judges the two first signals received respectively to confirm whether both first signals indicate that the first baffle 430 has a heat dissipation rubber ring.

[0053] If the controller receives two sets of first signals simultaneously indicating the presence of heat dissipation rubber rings on the first baffle 430, it will wait to proceed to the next step.

[0054] If either of the two sets of first signals indicates that there is no heat-dissipating rubber ring on the first baffle 430, the controller and the corresponding heat-dissipating rubber ring feeding mechanism 300 of the first baffle 430 will replenish the material until the controller simultaneously receives both sets of first signals indicating that there is a heat-dissipating rubber ring on the first baffle 430. During the replenishment of the corresponding first baffle 430, the controller controls the vibratory feeder 310 to start and simultaneously controls the first valve 340 to open the first air pipe 330, so that the heat-dissipating rubber ring is delivered to the corresponding first baffle 430, thereby completing the replenishment action.

[0055] Step S200: When two sets of first signals are received simultaneously, control the two second valves 421 to open the corresponding second air pipes 420, so that the second air pipes 420 blow air at the same time, and use the airflow to open the first baffle 430, so that the heat dissipation rubber ring falls from the first baffle 430 into the press-fit position 412.

[0056] Specifically, when two signals indicating the presence of a heat-dissipating rubber ring on the first baffle 430 are received simultaneously, the controller controls both second valves 421 to open the second air pipes 420. At this time, the second air pipes 420 blow air simultaneously, and the first baffle 430 opens the first channel under the action of the airflow, allowing the heat-dissipating rubber ring to fall from the first baffle 430 into the pressing position 412 below, in preparation for the next step.

[0057] S300: After the second air blowing pipe 420 starts blowing air, a timer is started. When the preset delay time is reached, the second valve 421 is controlled to close the second air blowing pipe 420, so that the first baffle 430 is reset. Then, the pressing drive 441 is controlled to drive the pressing rod 440 to move, so as to press the heat dissipation rubber ring on the pressing position 412 synchronously towards both ends of the rotor.

[0058] Specifically, the controller is equipped with a timing module. When the second air blowing pipe 420 starts blowing air, the timing module starts timing. When the preset delay time is reached, the timing module feeds back to the controller, which then controls the second valve 421 to close the second air blowing pipe 420, causing the first baffle 430 to reset. Then, the controller controls the pressing drive 441 to drive the pressing rod 440 to move, so as to synchronously press the heat dissipation rubber ring on the pressing position 412 towards both ends of the rotor, thereby completing the pressing action.

[0059] In some embodiments, if the sensor 510 still outputs the first signal after a preset delay time, it indicates that the heat dissipation rubber ring has not fallen into the pressing position 412 normally. At this time, the controller will pause the operation of the equipment and issue an alarm signal, waiting for the staff to troubleshoot the jamming fault. This avoids wasting production time due to air pressure and also prevents damage caused by the equipment operating with a fault. After the fault is cleared, the operator can manually reset the alarm signal, and the equipment will resume normal operation.

[0060] It should be noted that the preset delay time can be adjusted according to the actual size of the heat dissipation rubber ring and the operating speed of the equipment. Different specifications of motor rotors correspond to different sizes of heat dissipation rubber rings, and the required delay time will also vary. Specifically, it can be set according to the actual operating effect during the equipment debugging stage to ensure that the heat dissipation rubber ring can fall completely into the pressing position 412 before starting the pressing, thus ensuring the accuracy of the pressing action.

[0061] Step S400: When any set of sensors 510 detects that the corresponding first baffle 430 does not have a heat dissipation rubber ring, the vibrating plate 310 is started and the first valve 340 is opened to open the first air pipe 330 to replenish the heat dissipation rubber ring to the corresponding first baffle 430.

[0062] Specifically, after each pressing action is completed, each sensor 510 will continuously detect the status of the heat dissipation rubber ring on the corresponding first baffle 430. Once any sensor 510 detects that the first baffle 430 does not temporarily store the heat dissipation rubber ring, the controller will control the vibratory feeder 310 to start and open the first valve 340 of the first air pipe 330 to deliver the heat dissipation rubber ring to the corresponding first baffle 430. After the sensor 510 detects that the heat dissipation rubber ring is in place, the first air pipe 330 will be closed and the vibratory feeder 310 will be stopped, so as to prepare for the next round of pressing operation and not affect the progress of the next round of operation.

[0063] The control method for the motor rotor heat dissipation rubber ring installation equipment described in the second aspect of this application, by first detecting the position of the heat dissipation rubber rings at both ends of the first baffle 430, and only starting the pressing process after both ends are in place, can effectively avoid the problem of missing installation caused by the heat dissipation rubber rings on one side not being in place. Synchronous pressing also improves the efficiency of the pressing operation. Combined with the automated heat dissipation rubber ring replenishment process, no manual intervention is required, which can be adapted to long-term batch automated production, effectively improving production efficiency and product yield.

[0064] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
