Description

Technical Field

[0001] This invention relates to the field of motor manufacturing, specifically to a motor waterproof plug and retainer mounting device and mounting method. Background Technology

[0002] As a core driving component of various mechanical equipment, the waterproof performance of electric motors directly affects their service life and operational reliability. To prevent moisture from seeping into the motor through mounting holes and process holes in the motor housing, waterproof plugs are typically installed at the corresponding locations on the motor and secured with retainers to ensure a long-lasting and stable seal. Currently, the installation of motor waterproof plugs and retainers mainly relies on manual operation. Operators must manually remove and place the waterproof plug and press it into the motor's mounting hole, then remove and place the retainer and install it in place to secure the waterproof plug. However, both the waterproof plug and the retainer are small parts, making manual handling inconvenient, slow, and inefficient. Furthermore, consistency in installation position is difficult to guarantee, easily leading to quality problems such as improper installation of the waterproof plug and insecure retention of the retainer. In addition, prolonged repetitive manual operations result in high labor intensity for operators, which is detrimental to improving production efficiency.

[0003] Most existing automated equipment only handles the installation of single parts, treating the installation of waterproof plugs or retainers as separate processes. In actual production, the installation of waterproof plugs and retainers are two consecutive processes that need to be completed sequentially at the same mounting position on the same motor—first installing the waterproof plug, then installing the retainer to secure it. Using two separate machines for this process not only increases the floor space and procurement costs but also involves transferring and repositioning the workpiece between the two machines, which can easily lead to positioning errors, affecting assembly accuracy and overall production efficiency.

[0004] Therefore, it is necessary to provide a motor waterproof plug and retainer mounting device and mounting method. Summary of the Invention

[0005] The present invention provides a motor waterproof plug and retainer installation device, which effectively solves the problems of low efficiency and high labor intensity of existing devices.

[0006] The technical solution adopted in this invention is: a motor waterproof plug and retainer installation device, including a frame, several jigs, a conveyor line set on the frame for conveying the jigs, and also including a waterproof plug feeding mechanism, a retainer feeding mechanism, a first assembly mechanism for installing the waterproof plug, and a second assembly mechanism for installing the retainer, all set on the frame.

[0007] Furthermore, the first assembly mechanism includes a first material handling component and a first transfer module for driving the first material handling component to move. The first material handling component includes a first connecting frame driven by the first transfer module and a first suction tube vertically arranged on the first connecting frame.

[0008] Furthermore, the first transfer module includes a first support mounted on the frame, a first linear module A mounted on the first support along the Y-axis, a first linear module B mounted at the output end of the first linear module A along the X-axis, a first mounting plate mounted at the output end of the first linear module B along the Z-axis, a first linear guide rail A vertically mounted on the first mounting plate, a first connecting frame slidably mounted on the first linear guide rail A, and a first electric cylinder vertically mounted on the first mounting plate for driving the first connecting component along the first linear guide rail A. The first suction tube is mounted on the first connecting frame.

[0009] Furthermore, the waterproof plug feeding mechanism includes a first vibratory plate mounted on the frame, a first direct vibrator mounted on the frame and connected to the discharge end of the first vibratory plate, and a first material distribution component mounted on the frame and connected to the discharge end of the first direct vibrator.

[0010] Furthermore, the No. 1 material distribution component includes a No. 1 base mounted on the frame, a No. 1 linear guide rail B mounted on the No. 1 base along the X-axis, a No. 1 slide mounted on the No. 1 linear guide rail B, a No. 1 cylinder mounted on the No. 1 base for driving the No. 1 slide to slide along the No. 1 linear guide rail B, and a No. 1 fiber optic sensor mounted on the No. 1 base. The No. 1 slide is provided with a No. 1 receiving groove for receiving a waterproof plug from the No. 1 direct vibrator and a No. 1 sealing surface located on one side of the No. 1 receiving groove for sealing the No. 1 direct vibrator. The No. 1 fiber optic sensor is used to detect whether there is a waterproof plug in the No. 1 receiving groove.

[0011] Furthermore, the retainer feeding mechanism includes a second vibratory plate mounted on the frame, a second linear vibrator mounted on the frame and connected to the discharge end of the second vibratory plate, and a second material distribution assembly mounted on the frame and connected to the discharge end of the second linear vibrator. The second material distribution assembly includes a second base mounted on the frame, a second linear guide rail B mounted on the second base along the X-axis, a second slide mounted on the second linear guide rail B, a second cylinder mounted on the second base for driving the second slide to slide along the second linear guide rail B, and a second fiber optic sensor mounted on the second base. The second slide is provided with a second receiving groove for receiving the retainer's discharge from the second linear vibrator and a second sealing surface located on one side of the second receiving groove for sealing the second linear vibrator. The second fiber optic sensor is used to detect whether there is a retainer in the second receiving groove.

[0012] Furthermore, the second assembly mechanism includes a second support mounted on the frame, a second linear guide rail A mounted on the second support along the X-axis, a second linear module B slidably mounted on the second linear guide rail A, a second linear module A mounted on the second support for driving the second linear module B to slide along the second linear guide rail A, a second plate vertically mounted at the output end of the second linear module B, a second linear guide rail C vertically mounted on the second plate, a second sliding frame slidably mounted on the second linear guide rail C, a second electric cylinder mounted on the second plate for driving the second sliding frame to rise and fall along the second linear guide rail C, and a second suction nozzle mounted on the second sliding frame.

[0013] Furthermore, the conveyor line includes a mounting frame mounted on the frame, a conveyor line mounted on the mounting frame, a lifting assembly mounted on the frame for lifting fixtures on the conveyor line, and a blocking assembly mounted on the frame for blocking fixtures.

[0014] Furthermore, the stop assembly includes a rotary cylinder mounted on the mounting frame along the X-axis and a baffle mounted on the output end of the rotary cylinder. The baffle has at least two position states: the first position state is that the baffle is located on the upper surface of the speed increase line, and the second position state is that the baffle is located on the lower surface of the speed increase line. The top material assembly includes a base plate mounted on the frame, a top material frame slidably mounted on the base plate, and a No. 3 cylinder mounted on the base plate for driving the top material frame to rise and fall.

[0015] An installation method using the aforementioned motor waterproof plug and retainer installation device includes the following steps: S1, material preparation: a waterproof plug feeding mechanism supplies a waterproof plug to a first picking position, a retainer feeding mechanism supplies a retainer to a second picking position, and a conveyor line transports a fixture carrying a motor to a first installation station; S2, waterproof plug installation: a first assembly mechanism removes the waterproof plug from the first picking position and installs it onto the motor located at the first installation station; S3, product transfer: the conveyor line transports the fixture from the first installation station to the second installation station; S4, retainer installation: a second assembly mechanism removes the retainer from the second picking position and installs it onto the motor located at the second installation station; S5, material discharge: the conveyor line delivers the installed fixture.

[0016] Beneficial effects of the invention: This application integrates the waterproof plug feeding mechanism, the first assembly mechanism, the retainer feeding mechanism, and the second assembly mechanism into a single frame. Combined with a conveyor line, this enables the automatic transfer of fixtures between different workstations, allowing the installation of the waterproof plug and the fixing of the retainer to be completed sequentially on a single machine. Compared to using two separate machines or manual operation, this method offers a high degree of integration, reduces equipment footprint, eliminates the need for workpiece transfer and repositioning between different machines, and effectively improves production efficiency and assembly accuracy.

[0017] The lower end of the first suction tube of the first assembly mechanism is equipped with a positioning groove that matches the protrusion of the waterproof plug, which can accurately position the waterproof plug and ensure accurate installation. Several suction holes are arranged around the positioning groove so that the waterproof plug is evenly stressed and firmly adhered during adsorption and transportation, making it less likely to fall off or shift.

[0018] The waterproof plug feeding mechanism and the retainer feeding mechanism each employ a vibratory feeder in conjunction with a linear vibrator for orderly feeding, and a material separation component achieves individual material separation. The sliding block in the material separation component is equipped with both a receiving groove and a sealing surface. The receiving and sealing actions are simultaneously completed by a cylinder-driven sliding block, resulting in a compact structure and highly efficient operation. Fiber optic sensors continuously monitor the receiving groove for material availability, preventing empty or missed feedings and ensuring the feeding rhythm matches the assembly rhythm, guaranteeing long-term continuous and stable operation of the equipment.

[0019] The first assembly mechanism uses linear modules and electric cylinders in the X, Y, and Z axes to achieve precise positioning of the material handling components in three-dimensional space. The second assembly mechanism uses linear modules and electric cylinders to flexibly handle the suction nozzles. The stop / block component in the conveyor line uses a rotary cylinder to drive a baffle to switch between two positions, working in conjunction with the lifting component to stably lift the fixture to the precise assembly height. The smooth coordination of all mechanisms ensures efficient and stable operation of the entire machine, significantly reducing manual labor intensity. Attached Figure Description

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1As shown, the first embodiment provided in this application is a motor waterproof plug 100 and retainer 200 mounting device, including a frame 1, a plurality of jigs 2, a conveyor line 3 disposed on the frame 1 for conveying the jigs 2, and also including a waterproof plug feeding mechanism 4, a retainer feeding mechanism 5 disposed on the frame 1, a first assembly mechanism 6 for mounting the waterproof plug 100 and a second assembly mechanism 7 for mounting the retainer 200.

[0032] In actual use, the motor is placed in the fixture 2. The waterproof plug feeding mechanism 4 and the retainer feeding mechanism 5 respectively transport the waterproof plug 100 and the retainer 200 to the material pick-up positions of the first assembly mechanism 6 and the second assembly mechanism 7. The conveyor line 3 transports the fixture 2 to the position corresponding to the first assembly mechanism 6. The first assembly mechanism 6 takes out the waterproof plug 100 from the waterproof plug feeding mechanism 4 and installs it into the motor on the conveyor line 3. Then, the conveyor line 3 transports the fixture 2 to the corresponding position of the second assembly mechanism 7. Then, the second assembly mechanism 7 takes out the retainer 200 from the retainer feeding mechanism 5 and installs it into the motor product, so that the retainer 200 fixes the waterproof plug 100.

[0033] In the above design, by setting up a waterproof plug feeding mechanism 4, a retainer feeding mechanism 5, a first assembly mechanism 6, and a second assembly mechanism 7, the automated feeding and installation of the waterproof plug 100 and the retainer 200 are achieved. Compared with the traditional manual assembly method, this significantly reduces labor intensity, improves production efficiency, and ensures the consistency and stability of assembly quality.

[0034] Specifically: such as Figure 2 and Figure 3 As shown, the first assembly mechanism 6 includes a first material handling component and a first transfer module for driving the first material handling component to move. The first material handling component includes a first plate driven by the first transfer module and a first suction tube 62 vertically arranged on the first plate. The lower end of the first suction tube 62 is provided with a positioning groove 621 for positioning the product, and a plurality of suction holes 622 are provided around the positioning groove 621.

[0035] It should be noted that the waterproof plug 100 is provided with a protrusion 101 that mates with the positioning groove 621.

[0036] In actual use, the first transfer module drives the first pick-and-place assembly to move to the pick-up position of the waterproof plug feeding mechanism 4. This aligns the positioning groove 621 at the lower end of the first suction tube 62 with the waterproof plug 100. Several suction holes 622 arranged circumferentially along the positioning groove 621 firmly adsorb the waterproof plug 100 onto the lower end of the first suction tube 62 through negative pressure adsorption. Subsequently, the first transfer module drives the first pick-and-place assembly to move above the motor product on the conveyor line 3. After positioning and aligning the product through the positioning groove 621, the waterproof plug 100 is pressed into the installation position. Then, the vacuum of the first suction tube 62 is closed, and it detaches from the waterproof plug 100.

[0037] In the above design, the positioning groove 621 at the lower end of the first suction tube 62 precisely positions the waterproof plug 100, ensuring accurate installation. Several suction holes 622 are arranged around the positioning groove 621, so that the waterproof plug 100 is subjected to uniform force and firmly adsorbed during adsorption and transportation, making it less likely to fall off or shift, thus improving the reliability and accuracy of assembly.

[0038] Specifically: such as Figure 2 As shown, the first transfer module includes a first support 63 mounted on the frame 1, a first linear module A64 mounted on the first support 63 along the Y-axis, a first linear module B65 mounted at the output end of the first linear module A64 along the X-axis, a first mounting plate mounted at the output end of the first linear module B65 along the Z-axis, a first linear guide rail A67 vertically mounted on the first mounting plate, a first connecting frame 61 slidably mounted on the first linear guide rail A, and a first electric cylinder 66 vertically mounted on the first mounting plate for driving the first connecting piece along the first linear guide rail A67.

[0039] In actual use, linear module A64 drives linear module B65 to move along the Y-axis, linear module B65 drives mounting plate along the X-axis, and electric cylinder 66 drives connecting frame 61 to move up and down along linear guide rail A67 along the Z-axis. Together, these actions move the first material handling assembly along three axes to the target position to achieve material handling and installation.

[0040] In the above design, linear module A64, linear module B65, and electric cylinder 66 enable the precise positioning and flexible movement of the first material handling assembly in three-dimensional space, which can meet the requirements for positional accuracy and motion stability when installing the waterproof plug 100.

[0041] Specifically: such as Figure 4 As shown, the waterproof plug feeding mechanism 4 includes a first vibratory plate 41 mounted on the frame 1, a first direct vibrator 42 mounted on the frame 1 and connected to the discharge end of the first vibratory plate 41, and a first material distribution component 43 mounted on the frame 1 and connected to the discharge end of the first direct vibrator 42.

[0042] In actual use, the No. 1 vibratory plate 41 arranges the scattered waterproof plugs 100 in an orderly manner through vibration and conveys them to the No. 1 direct vibrator 42. The No. 1 direct vibrator 42 continues to convey the waterproof plugs 100 forward to the No. 1 material distribution assembly 43. The No. 1 material distribution assembly 43 receives one waterproof plug 100 per batch, and the first assembly mechanism 6 transfers the waterproof plugs 100 from the No. 1 material distribution assembly 43 and assembles them.

[0043] In the above design, the waterproof plug feeding mechanism 4 utilizes a mature and reliable feeding method that combines a No. 1 vibrating plate 41 and a No. 1 direct vibrator 42, which can automatically organize scattered materials into an orderly arrangement and provide continuous supply. The No. 1 material separating component 43 can separate the continuously conveyed waterproof plugs 100 one by one, which facilitates the first assembly mechanism 6 to accurately pick up materials, avoid material accumulation or jamming, and ensure that the feeding rhythm matches the assembly rhythm.

[0044] Specifically: such as Figure 5 As shown, the first material distribution component 43 includes a first base 431 mounted on the frame 1, a first linear guide rail B432 mounted on the first base 431 along the X-axis, a first slide block 433 slidably mounted on the first linear guide rail B432, a first cylinder 434 mounted on the first base 431 for driving the first slide block 433 to slide along the first linear guide rail B432, and a first fiber optic sensor 435 mounted on the first base 431. The first slide block 433 is provided with a first receiving groove 401 for receiving a waterproof plug 100 from the first direct vibrator 42 and a first sealing surface 402 located on one side of the first receiving groove 401 for sealing the first direct vibrator 42. The first fiber optic sensor 435 is used to detect whether there is a waterproof plug 100 in the first receiving groove 401.

[0045] In actual use, cylinder 434 first drives slide 433 to move along linear guide B432 to the receiving trough 401, which corresponds to the discharge end of vibrator 42. Then, vibrator 42 delivers waterproof plug 100 into receiving trough 401 of slide 433. Fiber optic sensor 435 detects whether waterproof plug 100 is in place in receiving trough 401. When waterproof plug 100 is detected, the PLC control system controls cylinder 434 to drive slide 433 to slide along linear guide B432, causing receiving trough 401 to carry waterproof plug 100 away from discharge end of vibrator 42. Simultaneously, sealing surface 402 on one side of receiving trough 401 moves to discharge end of vibrator 42 and seals it, preventing subsequent waterproof plugs 100 from being delivered, thus separating only one waterproof plug 100 at a time for use.

[0046] In the above design, a first receiving groove 401 and a first sealing surface 402 are simultaneously set on the first slide block 433. The receiving and sealing actions can be completed simultaneously by driving the first slide block 433 to slide through the first cylinder 434. The structure is compact and the operation is efficient. The first fiber optic sensor 435 can detect in real time whether there is a waterproof plug 100 in the receiving groove, avoiding empty or missed feeding, thus improving the reliability and automation of feeding.

[0047] Specifically: such as Figure 7 and Figure 8 As shown, the retainer feeding mechanism 5 includes a second vibratory plate 51 mounted on the frame 1, a second linear vibrator 52 mounted on the frame 1 and connected to the discharge end of the second vibratory plate 51, and a second material distribution assembly 53 mounted on the frame 1 and connected to the discharge end of the second linear vibrator 52; the second material distribution assembly 53 includes a second base 531 mounted on the frame 1, a second linear guide rail B532 mounted on the second base 531 along the X-axis, a second slide block 533 slidably mounted on the second linear guide rail B532, and a material distribution assembly 533 mounted on the second base 531. The second base 531 has a second cylinder 534 for driving the second slide 533 to slide along the second linear guide rail B532, and a second fiber optic sensor 535 set on the second base 531. The second slide 533 is provided with a second receiving groove 501 for receiving the retainer 200 of the second direct vibrator 52 and a second sealing surface 502 located on one side of the second receiving groove 501 for sealing the second direct vibrator 52. The second fiber optic sensor 535 is used to detect whether there is a retainer 200 in the second receiving groove 501.

[0048] In actual use, the retainers 200 are arranged in an orderly manner by the second vibrating plate 51 and conveyed to the second direct vibrator 52. The second direct vibrator 52 then conveys the retainers 200 forward to the second material distribution component 53. Before receiving material, the second-stage material distribution component 53 first drives the second-stage slide 533 to move along the second-stage linear guide rail B532 to the second-stage material receiving groove 501 to connect with the discharge end of the second-stage vibrator 52. Then, the second-stage vibrator 52 sends the retainer 200 to the second-stage material receiving groove 501 of the second-stage slide 533. After the second-stage fiber optic sensor 535 detects that the retainer 200 is in place, the second-stage cylinder 534 drives the second-stage slide 533 to slide along the second-stage linear guide rail B532, so that the second-stage material receiving groove 501 carries the retainer 200 away from the discharge end of the second-stage vibrator 52. At the same time, the second-stage sealing surface 502 seals the discharge end of the second-stage vibrator 52, realizing the sequential separation and feeding of the retainer 200.

[0049] In the above design, the retainer feeding mechanism 5 and the waterproof plug feeding mechanism 4 adopt similar material distribution structure designs, with a high degree of modularity. The second slide 533 simultaneously completes material receiving and sealing, and in conjunction with the second fiber optic sensor 535 for detection, it realizes the orderly, accurate, and sequential feeding of the retainer 200, providing a guarantee for the stable material picking of the second assembly mechanism 7.

[0050] Specifically: such as Figure 6 As shown, the second assembly mechanism 7 includes a second support 71 mounted on the frame 1, a second linear guide rail A72 mounted on the second support 71 along the X-axis, a second linear module B73 slidably mounted on the second linear guide rail A72, a second linear module A74 mounted on the second support 71 for driving the second linear module B73 to slide along the second linear guide rail A72, a second plate 75 vertically mounted at the output end of the second linear module B73, a second linear guide rail C76 vertically mounted on the second plate 75, a second sliding frame 77 slidably mounted on the second linear guide rail C76, a second electric cylinder 78 mounted on the second plate 75 for driving the second sliding frame 77 to rise and fall along the second linear guide rail C76, and a second suction nozzle 79 mounted on the second sliding frame 77.

[0051] In actual use, linear module A74 drives linear module B73 to move along the X-axis on linear guide rail A72. Linear module B73 drives plate 75 to move along the Y-axis, causing electric cylinder 78 and suction nozzle 79 to move synchronously in the X and Y axes, so that suction nozzle 79 moves directly above the material picking or unloading position. During material picking, electric cylinder 78 drives sliding frame 77 to descend along linear guide rail C76, causing suction nozzle 79 to adsorb retainer 200. Then, electric cylinder 78 drives sliding frame 77 to raise suction nozzle 79 to reset. During material unloading, electric cylinder 78 drives sliding frame 77 to descend along linear guide rail C76, causing suction nozzle 79 to assemble retainer 200 into the product. Then, electric cylinder 78 drives sliding frame 77 to raise suction nozzle 79 to reset.

[0052] In the above design, the second assembly mechanism 7 achieves precise positioning and flexible placement in three-dimensional space through the coordinated drive of the second linear module A74, the second linear module B73, and the second electric cylinder 78. The second suction nozzle 79 adsorbs and holds the retainer 200, which allows for quick and easy placement without damaging the workpiece. Combined with precise movement and lifting control, it can efficiently complete the automated installation of the retainer 200.

[0053] Specifically: such as Figure 9As shown, the conveyor line 3 includes a mounting frame 31 mounted on the frame 1, a speed-boosting line 32 mounted on the mounting frame 31, a lifting assembly 33 mounted on the frame 1 for lifting the jig 2 on the speed-boosting line 32, and a blocking assembly 34 mounted on the frame 1 for blocking the jig 2.

[0054] In actual use, fixture 2 is continuously conveyed on conveyor line 3 on mounting frame 31. When fixture 2 reaches the designated assembly station (corresponding to the first assembly mechanism 6 or the second assembly mechanism 7), the stop component 34 stops and positions fixture 2. Subsequently, the ejector component 33 lifts fixture 2 upward, removing it from the speed-increasing line 32 and positioning it at a precise assembly height, facilitating the installation of waterproof plug 100 and retainer 200 by the first assembly mechanism 6 and the second assembly mechanism 7. After installation, the ejector component 33 descends to return fixture 2 to conveyor line 3, the stop component 34 releases its obstruction, and fixture 2 continues to be conveyed forward to the next station.

[0055] In the above design, the conveyor line 3 enables the continuous automated flow of the fixture 2. The stop assembly 34 can precisely control the fixture 2 to stop at the designated station, and the lifting assembly 33 can lift and position the fixture 2 to the precise assembly height. The two work together to ensure the positional accuracy and stability of the fixture 2 during the assembly process, providing a reliable positioning basis for the precise installation of the waterproof plug 100 and the retainer 200.

[0056] Specifically: the stop assembly 34 includes a rotary cylinder mounted on the mounting frame 31 along the X-axis and a baffle mounted on the output end of the rotary cylinder. The baffle has at least two position states: the first position state is that the baffle is located on the upper end face of the conveyor line 3, and the second position state is that the baffle is located on the lower end face of the conveyor line 3. The top material assembly 33 includes a base plate mounted on the frame 1, a top material frame slidably mounted on the base plate, and a No. 3 cylinder mounted on the base plate for driving the top material frame to rise and fall.

[0057] In actual use, when fixture 2 needs to be stopped, the rotary cylinder drives the baffle to rotate, placing the baffle in the first position: the baffle is located on the upper end face of the conveyor line 3, blocking fixture 2 as it moves with the conveyor line 3, causing it to stop at the designated workstation. When fixture 2 is completed and needs to be released, the rotary cylinder drives the baffle to rotate to the second position: the baffle is located on the lower end face of the conveyor line 3, releasing the obstruction of fixture 2, allowing fixture 2 to continue moving forward with the conveyor line 3. After fixture 2 is stopped, the top material assembly 33 operates: the third cylinder drives the top material frame to rise and fall relative to the base plate. When the top material frame rises, it lifts fixture 2 on the conveyor line 3 upwards, detaching it from the conveyor line 3 for precise positioning. Then, the waterproof plug 100 or retainer 200 is assembled onto the lifted product. After assembly, the top material frame descends, causing fixture 2 to fall back onto the conveyor line 3 for continued conveying.

[0058] In the above design, the rotary cylinder drives the baffle to switch between two position states, which is simple in structure and reliable in operation, enabling precise stopping and releasing of fixture 2.
