[0002] After processing, various protective switches need to be assembled in sequence. Traditional assembly machines have complex structures, requiring manual operation when assembling different models. Widely used assembly equipment often uses cylinder drives, which can easily lead to deviations affecting processing quality in scenarios involving flipping or deflection requiring precision. Therefore, many matching correction or monitoring devices are designed, increasing the difficulty of maintenance and adjustment. Most importantly, the use, replacement, and adjustment of fixtures are inconvenient, making it difficult to meet the needs of efficient production. Utility Model Content

[0017] like Figures 1-4 As shown, an automatic assembly machine for circuit breaker housings includes a frame 1 and a mounting frame 2 spanning the frame 1. A robotic arm 3, linearly movable along a horizontal plane, is mounted on the mounting frame 2. The robotic arm 3 includes a slide block 4, a slider 5, a rotary motor 6, and a pneumatic gripper 7. The slide block 4 is slidably mounted on the mounting frame 2, and the slider 5 is slidably mounted on the slide block 4, reciprocating vertically. The rotary motor 6 is fixedly mounted below the slider 5, and the pneumatic gripper 7 is fixedly connected to the output end of the rotary motor 6. The mounting frame 2 supports the robotic arm 3. The horizontal displacement of the robotic arm 3 on the mounting frame 2 effectively moves and adjusts the pneumatic gripper 7, facilitating workpiece gripping. The robotic arm 3 can extend vertically, utilizing the relative movement between the slide block 4 and the slider 5. This movement can be pneumatically driven or in other forms, which will not be elaborated upon or limited here. The slide block 4 moves laterally relative to the mounting frame 2, while the slider 5 moves longitudinally relative to the slide block 4, increasing spatial freedom. Furthermore, the rotation control of the rotary motor 6 facilitates precise control of the installation tilt angle, improving accuracy. The ingenious use of direct motor control allows for smooth rotation during initial positioning. The pneumatic gripper 7's operation is a mature technology and will not be elaborated upon or limited here.
[0018] The frame 1 also has a movable opening 8 along the moving path of the pneumatic gripper 7. Below the movable opening 8, the frame 1 has a sub-frame 9. A fixture table 10, movably mounted on the sub-frame 9, is located at the movable opening 8. The fixture table 10 includes an upper frame 11 and a lower frame 12. The lower frame 12 moves linearly back and forth on the sub-frame 9. A rotating assembly rotatably connects the lower frame 12 to the upper frame 11. The top surface of the upper frame 11 has several clamping blocks 13 arranged around a common center, and slideways 14 for the clamping blocks 13 to slide. One end of the slideway 14 points towards the center, and the other end extends to the outer edge of the upper frame 11. The fixture table 10 can move linearly back and forth horizontally or rotate circumferentially to meet processing needs. Simultaneously, the clamping blocks 13 have a relatively high degree of design freedom, allowing them to converge or disperse towards the center. This structure can also adapt to various product specifications. The slider 5 is L-shaped, and a fixing frame 15 for mounting the rotary motor 6 is provided below the slider 5. This structure is convenient for processing and installation. Slots can be provided on the slider 5 for fastening, and the frame structure of the fixing frame 15 also facilitates the assembly of the rotary motor 6.
[0019] The subframe 9 is provided with an upper slide rail 16 and a side slide rail 17. The lower frame 12 has an upper limit part 18 and a lower limit part 19 on the side facing the subframe 9. The sliding limit directions between the upper limit part 18 and the upper slide rail 16, and between the lower limit part 19 and the side slide rail 17, are perpendicular. The lower frame 12 is inserted into the subframe 9 along its length to achieve a multi-directional limiting sliding effect. The design is ingenious and reasonable, meeting the design and usage requirements. The design of the sliding rail and the matching sliding module is based on a concave-convex meshing structure, which is a mature technology and will not be elaborated or limited here. In this embodiment, the upper limit part 18 and the lower limit part 19 are designed with concave and convex parts to facilitate limiting sliding assembly. The rotating assembly includes a rotating motor 20 and a coupling 21 connected to the output end of the rotating motor 20. The coupling 21 is linked to the upper frame 11. The coupling 21 in this embodiment is composed of multiple parts and its form is diverse and not limited to this, so it will not be described in detail. The upper frame 11 is rotated via coupling 21, utilizing the precision and controllability of the motor, which is more reliable than pneumatic rotation. The upper frame 11 is also equipped with an adjusting cylinder that drives the sliding of the clamping block 13. This allows for powerful clamping via cylinder drive, or additional fasteners for fixation. In comparison, manual adjustment and fastening are more cumbersome. While not limited to pneumatic operation, pneumatic operation is simply simpler and faster than pneumatic operation.
[0020] The mounting frame 2 is equipped with a transmission track or lead screw that drives the upper slide 4 to move. The two methods have different levels of precision and can be used as needed. The robotic arm 3 is set on opposite sides of the mounting frame 2. The frame 1 is also equipped with a positioning platform 22 below the mounting frame 2 to increase the number of workstations and improve efficiency. The positioning platform 22 is provided with several positioning holes 23 and positioning posts 24 placed at the positioning holes 23, so that some parts can be placed within the positioning range of the positioning posts 24, and then the other part can be flipped over for preliminary installation, depending on the actual use requirements.
