Description

Technical Field

[0001] This invention relates to the field of robot assembly technology, and in particular to a general-purpose press-fit robot for motor production. Background Technology

[0002] With the continuous improvement of industrial automation, press fitting technology is being used more and more widely in motor manufacturing. As an important assembly method for connecting bearings, rotors, stators and various supporting components, press fitting is not only one of the core processes for improving motor assembly efficiency, but also a fundamental guarantee for ensuring the stable operation of the entire motor.

[0003] In practice, some problems still exist: In the traditional motor assembly process, the inspection after workpiece positioning and pressing is usually done by manual visual inspection or manual use of inspection tools. This not only increases the workload of operators, but is also easily affected by human factors, resulting in large inspection errors. In particular, problems such as slight assembly offset at the bottom are difficult to identify intuitively and are often difficult to detect in time, causing unqualified products to flow into the next process and affecting the overall quality control. Although traditional electronic sensor inspection equipment has a certain degree of accuracy, it is often complex in structure, expensive, and easily affected by environmental interference. In the past, due to the lack of real-time pressure monitoring devices, operators could only estimate the pressure based on experience or set a fixed stroke for pressing. This method could not accurately control the actual pressure applied to the workpiece, and it was easy to cause problems such as pressing too tightly or too loosely, which could lead to damage to parts, poor fit or pressing failure. In severe cases, it could even affect the performance of the whole machine. At the same time, traditional equipment generally does not have an automatic cleaning function. After pressing, residual debris, lubricant or dust can easily accumulate, affecting the accuracy and efficiency of the next round of pressing. Summary of the Invention

[0005] (II) Technical Solution To achieve the above objectives, the main technical solution adopted by the present invention is as follows: A general-purpose press-fitting robot for motor production includes a mounting table, a pressure detection mechanism on one side of the inner wall of the mounting table, and a quality inspection auxiliary mechanism in the middle of the inner wall of the mounting table. A quality inspection auxiliary mechanism includes a marker pen, a push-button trigger switch, an alarm light, a gear ring, and a gear. The marker pen is provided on one side of the push-button trigger switch, and the push-button trigger switch is electrically connected to the alarm light. One side of the gear ring is meshed with the gear. A pressure detection mechanism, comprising a pressure detection switch, a pressing head, and a mounting plate, wherein the pressure detection switch is fixedly connected to the top of the mounting plate, and the pressing head is fixedly connected to the bottom of the mounting plate.

[0006] The quality inspection auxiliary mechanism also includes a base plate, mounting supports, an electric push rod, a limit plate, and a transmission motor. The bottom end of the base plate is fixedly connected to the top end of the mounting platform, and three mounting supports are fixedly connected to the top end of the base plate.

[0007] Each of the three mounting supports is fixedly connected to an electric push rod at its top end, and a limit plate is fixedly connected to the output end of each electric push rod.

[0008] The top of the base plate is where the motor workpiece is placed, and the inner side of each limiting plate is attached to the outer wall of the motor workpiece.

[0009] The bottom end of the drive motor is embedded in the inner wall of the mounting platform, the output end of the drive motor is fixedly connected to the bottom end of the gear, and the gear ring is rotatably connected to the top end of the base plate.

[0010] The inner wall of the mounting platform is connected to the press-fitting robot body. A fixing plate is slidably connected to the top of the toothed ring. A spring rod is fixedly connected to the top of the fixing plate. A top plate is fixedly connected to the free end of the spring rod.

[0011] The top of the top plate is fixedly connected to the bottom of the marker pen, and a pressure plate is fixedly connected to the inner side of the top plate. A threaded cylinder is fixedly connected to the bottom of the pressure plate, and a screw is threadedly connected to the inner wall of the threaded cylinder. The screw is placed on top of the push-button trigger switch.

[0012] The bottom of the push-button trigger switch is fixedly connected to a base, the top of the base is fixedly connected to a scale plate, the outer side of the screw is rotatably connected to an indicator plate, the indicator plate is slidably connected to the outer wall of the scale plate, and the alarm light is fixedly connected to the outer side of the base.

[0013] The fixing plate has locking holes in the middle and on the outside of the toothed ring. The top of the fixing plate has a locking pin, and the bottom end of the locking pin passes through the two locking holes in sequence.

[0014] The pressure detection mechanism also includes a detection platform and a cleaning push rod. The bottom end of the detection platform is fixedly connected to the top end of the mounting platform, and the top end of the detection platform is slidably connected to the cleaning push rod. The pressure detection switch is electrically connected to the alarm, and the top end of the pressure detection switch is fixedly connected to the output end of the pressing robot body. The alarm is electrically connected to the pressing robot body.

[0015] (III) Beneficial Effects The beneficial effects of this invention are: In this invention, an automated inspection mechanism is implemented to detect whether the motor workpiece is properly assembled. During use, the motor workpiece is first placed on the base plate and precisely positioned and securely fixed by the positioning groove and three limiting plates. After pressing, the transmission motor drives the gear and gear ring to rotate. The gear ring drives the fixing plate to inspect the bottom of the motor workpiece. When the motor workpiece is not properly assembled and causes one side of the bottom to sink, the marking pen will be squeezed by the bottom of the motor workpiece, causing displacement and marking the surface of the motor workpiece. At the same time, the marking pen moves downward in conjunction with the mounting plate, compressing the spring rod and pushing the pressure plate and screw, causing the screw to trigger the push-type trigger switch, illuminating the alarm light and reminding the operator. This structure does not require complex electronic detection devices. It achieves automatic identification and alarm prompts for assembly deviations through mechanical linkage. The detection process is sensitive and intuitive, helping to prevent improperly assembled products from flowing into subsequent processes, improving assembly yield and product reliability. In this invention, a pressure detection mechanism is set up, with a pressure detection switch fixedly connected to the upper part of the mounting plate and the bottom of the mounting plate connected to the pressing structure through a pressing head. When the pressing head presses the motor workpiece under the drive of the robot body, the pressure detection switch can monitor the applied pressure value in real time and transmit the signal to the pressing robot body. If the pressure is abnormal, such as exceeding the standard or being insufficient, the pressure-sensitive switch will immediately trigger the alarm light to provide an audible and visual alarm, thereby preventing pressing quality problems. At the same time, the detection table and the cleaning push rod work together. After pressing is completed, the cleaning push rod cleans the pressing area to prevent residual impurities from affecting the next assembly. The entire pressure detection mechanism is connected to the output end of the pressing robot body to achieve fully automatic control, greatly improving pressing accuracy and work efficiency.

[0018] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Please refer to Figures 1 to 6 As shown, a general-purpose press-fitting robot for motor production according to the present invention includes a mounting platform 1, a pressure detection mechanism 3 provided on one side of the inner wall of the mounting platform 1, and a quality inspection auxiliary mechanism 4 provided in the middle of the inner wall of the mounting platform 1. The quality inspection auxiliary mechanism 4 includes a marker pen 408, a push-button trigger switch 417, an alarm light 414, a gear ring 407, and a gear 405. The marker pen 408 is provided on one side of the push-button trigger switch 417. The push-button trigger switch 417 is electrically connected to the alarm light 414. One side of the gear ring 407 is meshed with the gear 405. The pressure detection mechanism 3 includes a pressure detection switch 304, a pressing head 305, and a mounting plate 306. The pressure detection switch 304 is fixedly connected to the top of the mounting plate 306, and the pressing head 305 is fixedly connected to the bottom of the mounting plate 306.

[0020] Optionally, the quality inspection auxiliary mechanism 4 also includes a base plate 401, mounting supports 402, electric push rods 403, a limiting plate 404, and a drive motor 406. The bottom end of the base plate 401 is fixedly connected to the top end of the mounting platform 1, and three mounting supports 402 are fixedly connected to the top end of the base plate 401. In actual implementation, the operator firmly installs the base plate 401 on the top of the mounting platform 1 of the pressing robot body 2 to ensure the stability of the inspection structure. The mounting supports 402 are installed on the base plate 401 and are respectively connected to the electric push rods 403 to provide a supporting foundation for the precise movement of the limiting plate 404. This structural design can effectively improve the rigidity and stability of the overall quality inspection auxiliary mechanism 4, provide a physical foundation for the reliable inspection of the motor workpiece 5, and help improve the inspection accuracy.

[0021] Optionally, each of the three mounting supports 402 is fixedly connected to an electric push rod 403 at its top end. Each electric push rod 403 is fixedly connected to a limiting plate 404 at its output end. In actual implementation, when the electric push rod 403 is activated, it drives the limiting plate 404 to move in a fixed direction until the limiting plate 404 fits against the outer wall of the motor workpiece 5. This structure enables the motor workpiece 5 to be quickly limited and positioned before pressing, reducing the offset of the motor workpiece 5, improving the centering accuracy of the pressing process, and contributing to the stability and accuracy of subsequent pressing and inspection processes.

[0022] Optionally, a motor workpiece 5 is placed on the top of the base plate 401, and the inner side of each limiting plate 404 is attached to the outer wall of the motor workpiece 5. In actual implementation, the user accurately places the motor workpiece 5 on the base plate 401, and the limiting plate 404 moves inward under the action of the electric push rod 403 and fits tightly against the outer wall of the motor workpiece 5. This process ensures that the motor workpiece 5 is accurately positioned and has a stable posture before pressing, effectively preventing the motor workpiece 5 from shaking or shifting during the pressing process, and improving the consistency and quality control level of assembly from the source.

[0023] Optionally, the bottom end of the drive motor 406 is embedded in the inner wall of the mounting platform 1, and the output end of the drive motor 406 is fixedly connected to the bottom end of the gear 405. The gear ring 407 is rotatably connected to the top of the base plate 401. In actual implementation, the drive motor 406 is installed inside the mounting platform 1, with a compact structure. The output end drives the gear ring 407 through the gear 405, which in turn drives the gear ring 407 to rotate. The rotation of the gear ring 407 provides rotational power for the quality inspection auxiliary mechanism 4, enabling it to perform 360° inspection around the bottom of the motor workpiece 5, significantly improving the detection range and coverage accuracy.

[0024] Optionally, the inner wall of the mounting platform 1 is connected to the press-fitting robot body 2. A fixed plate 411 is slidably connected to the top of the toothed ring 407. A spring rod 410 is fixedly connected to the top of the fixed plate 411. A top plate 409 is fixedly connected to the free end of the spring rod 410. In actual implementation, during installation, the fixed plate 411 can slide along the toothed ring 407 when it rotates. The connection structure between the spring rod 410 and the top plate 409 can achieve elastic response in the vertical direction. When the bottom of the motor workpiece 5 sinks during the detection process, the top plate 409 can respond by spring compression after being subjected to force, which helps to trigger the subsequent structure and enhances the sensitivity of assembly deviation identification.

[0025] Optionally, the top end of the top plate 409 is fixedly connected to the bottom end of the marker pen 408, and a pressure plate 421 is fixedly connected to the inner side of the top plate 409. A threaded cylinder 415 is fixedly connected to the bottom end of the pressure plate 421, and a screw 416 is threadedly connected to the inner wall of the threaded cylinder 415. The screw 416 is placed on top of the push-button trigger switch 417. In actual implementation, the marker pen 408 structure is linked with the top plate 409. When an assembly deviation is detected that causes the bottom of the motor workpiece 5 to sink, the marker pen 408 is passively compressed, which simultaneously drives the top plate 409 and its internal mechanism to move down synchronously. The design of the pressure plate 421 and the threaded connection structure can convert mechanical displacement into linear propulsion, so that the screw 416 can effectively trigger the push-button trigger switch 417.

[0026] Optionally, a base 418 is fixedly connected to the bottom of the push-button trigger switch 417, a scale plate 420 is fixedly connected to the top of the base 418, an indicator plate 419 is rotatably connected to the outside of the screw 416, the indicator plate 419 is slidably connected to the outer wall of the scale plate 420, and an alarm light 414 is fixedly connected to the outside of the base 418. In actual implementation, the pressing depth or pressure level can be intuitively judged by the positional relationship between the indicator plate 419 and the scale plate 420, realizing manual or auxiliary identification and judgment. The alarm light 414 is electrically connected to the push-button trigger switch 417.

[0027] Optionally, locking holes 413 are provided in the middle of the fixing plate 411 and on the outer side of the toothed ring 407. A locking pin 412 is provided on the top of the fixing plate 411. The bottom end of the locking pin 412 passes through the two locking holes 413 in sequence. In actual implementation, the fixing plate 411 and the toothed ring 407 are provided with locking holes 413 and locking pin 412. When testing is not required, the two can be firmly connected by locking pin 412 to prevent the toothed ring 407 from rotating accidentally or the testing mechanism from malfunctioning, thereby improving the structural stability and safety.

[0028] Optionally, the pressure detection mechanism 3 also includes a detection platform 302 and a cleaning push rod 303. The bottom end of the detection platform 302 is fixedly connected to the top end of the mounting platform 1, and the top end of the detection platform 302 is slidably connected to the cleaning push rod 303. The pressure detection switch 304 is electrically connected to the alarm 301. The top end of the pressure detection switch 304 is fixedly connected to the output end of the pressing robot body 2, and the alarm 301 is electrically connected to the pressing robot body 2. In actual implementation, the pressure detection switch 304 is installed at the pressing output end, which can detect the applied force in real time and trigger an alarm in conjunction with the alarm 301.

[0029] Working principle: The user first places the motor workpiece 5 on the base plate 401 and aligns it with the positioning groove on the base plate 401. Then, the user starts the three electric push rods 403. The output ends of the electric push rods 403 drive the three limiting plates 404 to move, so that they are close to the outer wall of the motor workpiece 5, thereby limiting the motor and achieving initial fixation. After positioning is completed, the user starts the pressing robot body 2 to press the motor workpiece 5. After pressing is completed, the user can start the drive motor 406. The output end of the drive motor 406 drives the gear 405 to rotate, thereby driving the meshing gear ring 4. Rotation occurs at 07. The top of the gear ring 407 slides into contact with the fixing plate 411. Under the influence of the gear ring 407, the fixing plate 411 rotates circumferentially around the bottom of the motor workpiece 5 for detection. When there is an assembly misalignment in the motor workpiece 5, especially when one side of the bottom is not properly assembled and causes significant sinking, this sinking position will be touched and squeezed by the marking pen 408 during rotation. After being squeezed, the marking pen 408 moves downward and automatically marks the workpiece surface. At the same time, it drives the mounting plate 306 to press down. The mounting plate 306 further compresses the spring rod 410 and pushes the pressure plate 421 below. The pressure plate 421 continues to act downwards on the screw 416, causing it to squeeze and trigger the push-button trigger switch 417. Once activated, the switch illuminates the alarm light 414, alerting the user to an installation abnormality in the motor. This facilitates timely detection and handling of the problem. This detection process is simple to operate and highly responsive, effectively preventing subsequent quality issues caused by assembly deviations. A pressure detection switch 304 is fixedly connected to the upper part of the mounting plate 306. The bottom of the mounting plate 306 is connected to the pressing structure via a pressing head 305. When the pressing head 305 presses the motor workpiece 5 under the drive of the robot body, the pressure... The force detection switch 304 can monitor the applied pressure value in real time and transmit the signal to the pressing robot body 2. If the pressure is abnormal, such as exceeding the standard or being insufficient, the pressure-sensitive switch will immediately trigger the alarm light 414 to provide an audible and visual alarm, thereby preventing pressing quality problems. At the same time, the detection table 302 and the cleaning push rod 303 work together. After pressing is completed, the cleaning push rod 303 cleans the pressing area to prevent residual impurities from affecting the next assembly. The entire pressure detection mechanism 3 is connected to the output end of the pressing robot body 2 to achieve fully automatic control, which greatly improves pressing accuracy and work efficiency.
