Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of waterproof terminals for electric motors, and in particular to an automatic assembly equipment for waterproof terminals for electric motors. Background Technology

[0002] As a crucial power output device, electric motors are widely used in various complex environments, making the reliability of their electrical connections paramount. Waterproof terminal blocks are key components ensuring the safety of motor electrical connections under harsh conditions such as humidity and dust. They are typically assembled from end caps, a main body, and a sealed inner tube, and their assembly quality directly affects the motor's waterproof performance and long-term operational stability. For a long time, the assembly process of these waterproof terminal blocks has heavily relied on manual operation. Workers must manually pick up materials, align them, and precisely press or tighten tiny parts one by one. This work mode has significant drawbacks: First, the precision of manual operation is difficult to guarantee; even minor misalignment between parts or incorrect installation of the sealed inner tube can lead to seal failure, creating a risk of leakage and affecting product qualification rates. Second, manual assembly steps are cumbersome and inefficient, especially under large-scale production demands, becoming a bottleneck for capacity expansion. Third, with the continuous rise in labor costs, reliance on intensive manual operation significantly increases production costs.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

The second slide rail 13 is arranged vertically, and the tightening mechanism 9 can slide and move up and down along the second slide rail 13 to move away from or approach the tightening fixture 5. In this embodiment, both the first slide rail 12 and the second slide rail 13 are made of profiles with grooves on the outer side, and the grooves serve as track grooves. The first slide rail 12 is fixedly installed on the bracket 11 by screws, and the second slide rail 13 is fixedly installed on the base 1 by screws.

[0049] Please see Figures 1 to 2As shown, the clamping mechanism 6 is movably mounted on the bracket 11 and is used to clamp and convey the end cap 01 from the loading fixture 2 into the tightening fixture 5, and to remove the assembled assembly from the tightening fixture 5 and place it into the collection container 3. The clamping mechanism 6 includes a first cylinder 61, a second cylinder 62, a first mounting frame 63, a finger cylinder 64, and four first pulleys 65. The first cylinder 61 is fixedly mounted on the bracket 11 by screws and drives the first mounting frame 63. The second cylinder 62 is fixedly mounted on the first mounting frame 63 by screws and drives the finger cylinder 64. The four first pulleys 65 are respectively rotatably mounted on the first mounting frame 63 and slidably connected to the first slide rail 12. The first cylinder 61 is used to drive the first mounting frame 63 to slide back and forth along the first slide rail 12. The second cylinder 62 is used to drive the finger cylinder 64 to move up and down. The finger cylinder 64 is used to clamp the end cap 01 and the assembly. In this embodiment, the clamping mechanism 6 can realize lifting and lowering movement, horizontal reciprocating movement, and clamping and loosening actions; the end of the telescopic rod of the first cylinder 61 is provided with an external thread, and a through hole is provided on one side of the first mounting bracket 63. The end of the telescopic rod of the first cylinder 61 passes through the through hole and is locked and fixed by a nut to connect to the first mounting bracket 63; the end of the telescopic rod of the second cylinder 62 is provided with an external thread, and a flange is fixedly connected by a nut. The flange is fixedly connected to the finger cylinder 64 by screws. The first mounting bracket 63 is integrally formed by 3D printing technology. The four first pulleys 65 are installed on the first mounting bracket 63 by bolts and bearings and slide into the groove of the first slide rail 12. The first mounting bracket 63 is stably slidably connected on the first slide rail 12 by the limiting effect of the groove wall on the first pulleys 65.

[0050] Please see Figures 1 to 2 As shown, the pushing mechanism 7 is mounted on the bracket 11 and is used to push the sealed inner tube 03 into the main body 02 in the assembly fixture 4 to form an assembly, and to push the assembly on the assembly fixture 4 into the tightening fixture 5. The pushing mechanism 7 includes a third cylinder 71 and a push rod 72. The third cylinder 71 is mounted on the bracket 11 and drives one end of the push rod 72, while the other end of the push rod 72 is movably disposed in the assembly fixture 4. In this embodiment, the third cylinder 71 is horizontally mounted via the bracket 11 and drives the push rod 72 to extend in a direction perpendicular to the moving direction of the clamping mechanism 6. One end of the push rod 72 is provided with an internal thread, and the end of the extension rod of the third cylinder 71 is provided with an external thread. The push rod 72 and the extension rod are fixed by a threaded connection. When the extension rod of the third cylinder 71 extends, the push rod 72 extends forward into the assembly fixture 4 and pushes the assembly in the assembly fixture 4 out, causing the assembly to fall vertically into the tightening fixture 5.

[0051] Please see Figures 1 to 2As shown, the blocking mechanism 8 is mounted on the bracket 11 and is positioned opposite to the pushing mechanism 7. It works in conjunction with the pushing mechanism 7 to assemble the sealing inner tube 03 onto the main body 02 in the assembly fixture 4 to form an assembly. The blocking mechanism 8 includes a fourth cylinder 81 and a push rod 82. The fourth cylinder 81 is fixedly mounted on the bracket 11 and drives one end of the push rod 82. The other end of the push rod 82 can move in and out of the assembly fixture 4. In this embodiment, the end of the telescopic rod of the fourth cylinder 81 is provided with an external thread, and one section of the push rod 82 is provided with an internal thread. The push rod 82 and the telescopic rod are fixed together by a threaded connection. The other end of the push rod 82 is provided with a clearance hole to avoid the end of the main body 02, allowing the end of the push rod 82 to abut against the step of the main body 02, thus distributing the force more evenly and making the assembly of the sealing inner tube 03 and the main body 02 more precise. When the extension rod of the fourth cylinder 81 extends, the push rod 82 extends backward into the assembly fixture 4 to hold the main body 02 in place, and the pushing mechanism 7 pushes the sealed inner tube 03 into the main body 02 to form an assembly; then the fourth cylinder 81 resets, releasing the constraint on the main body 02, and the pushing mechanism 7 pushes the assembly into the tightening fixture 5.

[0052] In this embodiment, the support 11 of the pushing mechanism 7, the assembly fixture 4, and the blocking mechanism 8 have the same structure, but differ in size. The three supports 11 are located on the same straight line. The height of the pushing mechanism 7 is the same as the height of the blocking mechanism 8. The push rod 72, the assembly groove 43 of the assembly fixture 4, and the top rod 82 are located on the same axis. The third cylinder 71 and the fourth cylinder 81 are arranged opposite to each other on the front and rear sides of the assembly fixture 4, with opposite driving directions and opposite forces. In actual production, the worker puts the main body 02 and the sealing inner tube 03 into the assembly fixture 4. The fourth cylinder 81 drives the top rod 82 to hold the main body 02 in place. The third cylinder 71 drives the push rod 72 to push the sealing inner tube 03 into the main body 02 to assemble it into a combination. The fourth cylinder 81 drives the top rod 82 to reset to release the limit. The third cylinder 71 drives the push rod 72 to push the combination out of the assembly fixture 4. The combination falls into the tightening fixture 5. The third cylinder 71 drives the push rod 72 to reset.

[0053] Please see Figures 1 to 2 , Figures 5 to 6As shown, the tightening mechanism 9 is movably mounted on the bracket 11 and is used to tighten the end cap 01 onto the assembly formed by the main body 02 and the sealing inner tube 03 to form the assembly. The tightening mechanism 9 includes a fifth cylinder 91, a second mounting bracket 92, a motor 93, a sleeve 94, and four second pulleys 95. The fifth cylinder 91 is mounted on the base 1 and drives the second mounting bracket 92. The motor 93 is mounted on the second mounting bracket 92 and drives the sleeve 94. The sleeve 94 is used to tighten the end cap 01 to lock the end cap 01 and the assembly. The four second pulleys 95 are rotatably mounted on the second mounting bracket 92 and slidably connected to the second slide rail 13. The fifth cylinder 91 is used to drive the second mounting bracket 92 to move up and down, and the motor 93 is used to drive the sleeve 94 to rotate. In this embodiment, the telescopic rod of the fifth cylinder 91 is provided with an external thread at its end and is equipped with a "Z"-shaped connector. One end of the connector is fixedly connected to the telescopic rod of the fifth cylinder 91 by a nut, and the other end of the connector is fixedly connected to the second mounting bracket 92 by a screw and a nut. Four second pulleys 95 are installed on the second mounting bracket 92 by bolts and bearings and slide into the groove of the second slide rail 13. The second mounting bracket 92 is stably slidably connected on the second slide rail 13 by the limiting effect of the groove wall on the second pulleys 95. The motor 93 is installed on the second mounting bracket 92 by screws. The drive shaft of the motor 93 is fixedly inserted into the sleeve 94 and limited by a fixing pin. The inner cross-section of the sleeve 94 is a regular hexagon that matches the shape of the end cap. When the assembly enters the tightening fixture 5, the clamping mechanism 6 also sends the end cap 01 onto the assembly. The fifth cylinder 91 drives the telescopic rod to retract, causing the second mounting bracket 92 to slide downward along the second slide rail 13, so that the sleeve 94 is fitted over the end cap 01. The motor 93 drives the sleeve 94 to rotate, thereby screwing the end cap 01 onto the assembly to form an assembly. The motor 93 stops rotating, and the fifth cylinder 91 drives the second mounting bracket 92 to reset.

[0054] An electrical control assembly (not shown in the figure) is mounted on the base 1 and controls the clamping mechanism 6, the pushing mechanism 7, the blocking mechanism 8, and the tightening mechanism 9. In this embodiment, the electrical control assembly includes a PLC (Siemens S7-200 series optional), a 24V power supply, six solenoid valves, and a time relay. The PLC controls the six solenoid valves, which are connected via air pipes to the first cylinder 61, the second cylinder 62, the third cylinder 71, the fourth cylinder 81, the fifth cylinder 91, and the finger cylinder 64, respectively, and control their airflow. The 24V power supply is electrically connected to the PLC. The PLC is electrically connected to the time relay, and the PLC has a control program with time parameters. The time relay times the data, and the control program coordinates with the cylinders and motors to perform corresponding actions, achieving automated assembly of waterproof terminals. In some other embodiments, a position sensor can be configured to provide real-time feedback on whether the cylinder stroke is complete, further achieving precise assembly.

[0055] In actual production, the end cap 01 is manually placed into the feeding fixture 2, the main body 02 and the sealing inner tube 03 are placed into the assembly fixture 4, the electrical control component is activated, and the blocking mechanism 8 is activated to embed the sealing inner tube 03 into the main body 02 to form an assembly. The blocking mechanism 8 is reset, the pushing mechanism 7 pushes the assembly into the tightening fixture 5 and then resets, the clamping mechanism 6 clamps and transports the end cap 01 in the feeding fixture 2 to the assembly in the tightening fixture 5, the clamping mechanism 6 is reset, the tightening mechanism 9 rotates and tightens the end cap 01 to connect it to the assembly to form an assembly, the tightening mechanism 9 is reset, the clamping mechanism 6 clamps and transports the assembly in the tightening fixture 5 to the collection container 3, the clamping mechanism 6 is reset, and the automatic assembly of a waterproof terminal block for a motor is completed. This automatic assembly equipment for waterproof terminals of electric motors integrates the base 1, feeding fixture 2, assembly fixture 4, tightening fixture 5, clamping mechanism 6, pushing mechanism 7, blocking mechanism 8, tightening mechanism 9 and electrical control components to replace manual assembly, realize the automated assembly of waterproof terminals, improve assembly accuracy and production efficiency, and save labor costs.

[0056] Please see Figure 3 As shown, the loading fixture 2 includes a loading hole 21 and a positioning groove 22. The lower end of the loading hole 21 is connected to the positioning groove 22, and the positioning groove 22 is set at the initial position of the clamping mechanism 6. In this embodiment, the loading hole 21 of the loading fixture 2 is a vertical through hole. The loading hole 21 and the positioning groove 22 are connected by an inclined hole. The size of the positioning groove 22, the loading hole 21 and the inclined hole are all such that only one end cap 01 can pass through at the same time. Two or more end caps 01 cannot pass through side by side, so that the position of each end cap 01 when it reaches the positioning groove 22 is suitable for the finger cylinder 64 to grasp and place it on the assembly. The size of the groove opening of the positioning groove 22 is only enough for the finger cylinder 64 to take out one end cap 01 at a time. The positioning groove 22 is offset from the direct bottom of the loading hole 21 and the groove opening is located directly below the initial position of the finger cylinder 64, which facilitates the finger cylinder 64 to descend and grasp the end cap 01 in the positioning groove 22. Workers place multiple end caps 01 into the upper part of the loading hole 21 in a uniform position. The multiple end caps 01 enter the positioning groove 22 one by one through the inclined hole. The finger cylinder 64 grabs one end cap 01 at a time. After the end cap 01 in the positioning groove 22 is removed, the next end cap 01 automatically falls into the positioning groove 22 due to its own gravity.

[0057] Please see Figure 4As shown, the assembly fixture 4 includes a first limiting groove 41, a second limiting groove 42, and an assembly groove 43. The first limiting groove 41 and the second limiting groove 42 are connected and parallel to each other. The assembly groove 43 is connected to the first limiting groove 41 and the second limiting groove 42 respectively and is perpendicular to the first limiting groove 41 and the second limiting groove 42. The first limiting groove 41 is used to limit the sealing inner tube 03, and the second limiting groove 42 is used to limit the main body 02. The push rod 82 moves in and out of the assembly groove 43 to assemble the main body 02 and the sealing inner tube 03. In this embodiment, the first limiting groove 41 and the second limiting groove 42 are overlapped and formed by inwardly protruding steps on both sides. The second limiting groove 42 has the same steps on both sides of the groove opening. The two steps limit the main body 02, so that the position of the main body 02 entering the assembly groove 43 from the second limiting groove 42 can be accurately assembled with the sealing inner tube 03. There are no steps to block the connection between the assembly groove 43 and the second limiting groove 42, so that the assembly can be smoothly separated from the assembly groove 43. The lower end of the first limiting groove 41 is provided with a notch, which is located on the opposite side of the assembly groove 43. The push rod 72 enters the first limiting groove 41 through the notch and passes through the second limiting groove 42 to push the assembly of the assembly groove 43 out.

[0058] Please see Figure 2 As shown, it also includes a limiting tube 44, which is connected to and coaxially arranged with the assembly groove 43. The end of the push rod 72 is movably accommodated within the limiting tube 44 and moves in and out of the assembly groove 43 through the limiting tube 44. In this embodiment, the limiting tube 44 corresponds to the notch position of the assembly fixture 4 and is fixedly connected to the assembly fixture 4 by screws. When the third cylinder 71 is not working, the end of the push rod 72 is located inside the limiting tube 44 to avoid affecting the assembly position of the sealing inner tube 03 in the first limiting groove 41. When the telescopic rod of the third cylinder 71 extends, the push rod 72 passes through the limiting tube 44 and enters the assembly fixture 4. The setting of the limiting tube 44 plays a role in limiting and stabilizing the push rod 72, improving the pushing accuracy of the push rod 72.

[0059] Please see Figure 5 As shown, the tightening fixture 5 includes a limiting hole 51, the shape of the inner wall structure of the limiting hole 51 being adapted to the shape of one end of the main body 02. In this embodiment, the upper cross-section of the limiting hole 51 is a regular hexagon that adapts to the outer shape of the main body 02, and the lower cross-section of the limiting hole 51 is circular; the height difference between the tightening fixture 5 and the assembly groove 43 is equal to or less than half the total length of the assembly, so that when the push rod 72 pushes the assembly out, the assembly can accurately fall into the limiting hole 51 and be in the correct position.

[0060] In summary, this utility model, by integrating the base 1, feeding fixture 2, assembly fixture 4, tightening fixture 5, clamping mechanism 6, pushing mechanism 7, blocking mechanism 8, tightening mechanism 9, and electrical control components, replaces manual assembly, realizes automated assembly of waterproof terminals, improves assembly accuracy and production efficiency, and saves labor costs.

[0061] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
