Description

Technical Field

[0001] This application relates to the field of circuit breaker assembly equipment technology, and in particular to an automated feeding device for pole-mounted circuit breakers. Background Technology

[0002] With the rapid development of industrial automation technology, the manufacturing industry is moving towards intelligence, efficiency, and precision. As an important part of the electrical manufacturing industry, the production process of circuit breakers is complex and requires high precision; their production efficiency and product quality directly affect a company's market competitiveness. In the circuit breaker production process, the material loading stage is one of the key processes on the entire production line.

[0003] In the actual production process of circuit breakers, traditional feeding methods rely heavily on manual operation. Manual feeding requires operators to place each circuit breaker in a designated position, which is time-consuming, especially in large-scale production. This efficiency is insufficient to meet the demands of modern production lines. Furthermore, manual operation involves repeatedly bending over, moving, and placing circuit breakers, resulting in high labor intensity and operator fatigue, which in turn affects work efficiency and health. Therefore, an automated feeding mechanism for circuit breaker production lines is needed. By adding an automated feeding and pushing mechanism, intelligent and automated feeding of circuit breakers on the production line can be achieved, solving many of the problems associated with traditional feeding methods. Utility Model Content

[0004] To facilitate automated feeding of circuit breakers on the production line, an automated feeding device for pole-mounted circuit breakers is provided.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] An automated feeding device for pole-mounted circuit breakers includes a transversely arranged conveying mechanism. The conveying mechanism includes a conveying platform on which the pole-mounted circuit breaker is mounted. A feeding mechanism is installed on one side of the conveying platform. The feeding mechanism includes a transverse cylinder mounted on the conveying platform. A support member is fixed on the output shaft of the transverse cylinder. A longitudinal cylinder is mounted on the support member. The longitudinal cylinder is perpendicular to the transverse cylinder, and a pusher member is provided on the output shaft of the longitudinal cylinder. A pusher rod is fixed on the pusher member. A guide column is installed on one side of the pole-mounted circuit breaker. A fixing plate is fixed at the lower end of the guide column, and a fixing groove for the pusher rod to be inserted is opened on the fixing plate.

[0007] By adopting the above technical solution, the combined use of the horizontal cylinder and the vertical cylinder can precisely control the position of the push rod, ensuring that the push rod is accurately inserted into the fixed slot of the pole-mounted circuit breaker, thereby achieving precise positioning. At the same time, the cooperation of the horizontal cylinder and the vertical cylinder realizes the automatic feeding process of the pole-mounted circuit breaker, reducing the need for manual operation and improving production efficiency.

[0008] Optionally, the conveyor platform is equipped with a transverse guide rail coaxial with the output shaft of the transverse cylinder, and the support member is slidably connected to the transverse guide rail.

[0009] By adopting the above technical solution, the transverse guide rail provides stable guidance and support for the support component, ensuring the straightness and stability of the support component during transverse movement, reducing vibration and displacement deviation of the support component during movement, and improving the accuracy and reliability of feeding.

[0010] Optionally, a longitudinal guide rail is fixed on the support member, the longitudinal guide rail is parallel to the longitudinal cylinder, and the pusher is slidably connected to the longitudinal guide rail.

[0011] By adopting the above technical solution, the longitudinal guide rail provides stable guidance and support for the pusher, ensuring the straightness and stability of the pusher during longitudinal movement, reducing vibration and displacement deviation of the pusher during movement, and improving the accuracy and reliability of feeding.

[0012] Optionally, the end of the push rod is chamfered.

[0013] By adopting the above technical solution, the chamfer design helps the push rod to accurately enter the fixed groove, ensuring the correctness and stability of the insertion, reducing the friction during insertion, reducing the movement resistance of the push rod, making the insertion process smoother, and reducing energy loss.

[0014] Optionally, an airflow nozzle is installed on the end of the push rod facing the fixed groove, and the length of the airflow nozzle is less than the distance from the end of the push rod to the fixed groove.

[0015] By adopting the above technical solution, the airflow nozzle can be used to clean the surface of the fixing groove or push rod before insertion, to prevent dust or impurities from accumulating and affecting the accuracy of insertion, and to extend the service life of the equipment. Since the length of the airflow nozzle is less than the distance from the end of the push rod to the fixing groove, the nozzle will not contact the fixing groove, which can avoid the nozzle being worn or blocked by impurities in the fixing groove.

[0016] Optionally, at least two intelligent limit switches are installed on the conveyor platform, and the intelligent limit switches are electrically connected to the control system in the feeding mechanism.

[0017] By adopting the above technical solution, when the horizontal or vertical cylinder pushes the pole-mounted circuit breaker close to the target position, the limit switch sends a deceleration signal in advance, so that the cylinder slowly moves to the accurate position and then stops, thereby achieving more precise positioning control.

[0018] Optionally, a vertical limiting shaft is fixed on the side of the pusher rod facing the pusher component, and the pusher component has multiple limiting grooves for the ends of the limiting shaft to be inserted into each other, and the multiple limiting grooves are relatively parallel to each other.

[0019] By adopting the above technical solution, the push rod can be snapped into different limit grooves through the limit shaft, which can adapt to pole-mounted circuit breakers of different sizes and shapes, thus improving the versatility of the equipment.

[0020] Optionally, limiting protrusions are fixed on both sides of the limiting shaft, and a supporting spring is fixed between the limiting protrusions and the limiting shaft. The pusher also has multiple protrusions that communicate with the limiting groove, and the limiting protrusions are engaged with the protrusions.

[0021] By adopting the above technical solution, the structure in which the limiting protrusion and the protrusion groove are engaged fixes the push rod in the longitudinal direction, reducing the displacement deviation of the push rod during the movement process and improving the reliability of the push rod.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. The combined use of horizontal and vertical cylinders can precisely control the position of the push rod, ensuring that the push rod is accurately inserted into the fixed slot of the pole-mounted circuit breaker, thereby achieving precise positioning and realizing the automatic feeding process of the pole-mounted circuit breaker, reducing the need for manual operation and improving production efficiency.

[0024] 2. An airflow nozzle is installed on the end of the push rod. The airflow nozzle is used to clean the surface of the fixing groove or push rod before insertion to prevent dust or impurities from accumulating and affecting the accuracy of insertion, thus extending the service life of the equipment.

Detailed Implementation

[0032] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0033] Example 1

[0034] As attached Figure 1 and attached Figure 2 As shown, an automated feeding device for pole-mounted circuit breakers includes a conveying mechanism 1, a feeding mechanism 2, and a pole-mounted circuit breaker 3.

[0035] The conveying mechanism 1 includes a horizontally arranged conveying platform 11, on which a horizontally arranged conveying slide rail 12 is fixed. The column-mounted circuit breaker 3 slides on the conveying slide rail 12 for conveying. A guide column 4 is installed on the side of the column-mounted circuit breaker 3 facing away from the conveying direction of the conveying platform 11. The upper end of the guide column 4 is rotatably connected to the column-mounted circuit breaker 3. The lower end of the guide column 4 is slidably connected to the conveying platform 11 through the conveying slide rail 12. A fixing plate 41 is also fixed to the lower end of the guide column 4, and a fixing groove 411 is opened on the fixing plate 41.

[0036] As attached Figure 2 and attached Figure 3 As shown, the feeding mechanism 2 is located on one side of the conveying mechanism 1. The feeding mechanism 2 includes a transverse cylinder 21 and a transverse guide rail 22. The transverse cylinder 21 is fixedly connected to the conveying table 11. A support member 23 is installed on the output shaft of the transverse cylinder 21. The support member 23 is rectangular in shape. The transverse guide rail 22 is coaxial with the output shaft of the transverse cylinder 21. The transverse guide rail 22 is located below the support member 23 and is slidably connected to the support member 23. The transverse guide rail 22 provides stable guidance and support for the support member 23, ensuring the straightness and stability of the support member 23 when it moves laterally, reducing the vibration and displacement deviation of the support member 23 during the movement, and improving the accuracy and reliability of feeding.

[0037] The feeding mechanism 2 also includes a longitudinal cylinder 24, a pusher 25 and a longitudinal guide rail 26. The longitudinal cylinder 24 is perpendicular to the transverse cylinder 21 and is located above the support member 23. The pusher 25 is L-shaped. One side of the pusher 25 is fixedly connected to the output shaft of the longitudinal cylinder 24, and the other side of the pusher 25 is located above the longitudinal cylinder 24.

[0038] The longitudinal guide rail 26 is perpendicular to the transverse guide rail 22. The longitudinal guide rail 26 is fixedly connected to the upper end of the support member 23, and the longitudinal guide rail 26 is relatively parallel to the longitudinal cylinder 24. The longitudinal guide rail 26 is slidably connected to the pusher member 25. The longitudinal guide rail 26 provides stable guidance and support for the pusher member 25, ensuring the straightness and stability of the pusher member 25 when moving longitudinally, reducing the vibration and displacement deviation of the pusher member 25 during the movement process, and improving the accuracy and reliability of feeding.

[0039] The feeding mechanism 2 also includes a push rod 27, which is fixedly connected to the upper end of the pusher 25. The push rod 27 is inserted into the fixed groove 411, and the end of the push rod 27 is chamfered. The chamfer design helps the push rod 27 to accurately enter the fixed groove 411, ensuring the correctness and stability of the insertion and reducing the friction during insertion.

[0040] A chain belt 13 is also installed on the conveyor table 11, and the support member 23 is fixedly connected to the chain belt 13 on the side facing the conveyor table 11. When the horizontal cylinder 21 drives the support member 23 to move horizontally, the chain belt 13 will also drive the support member 23 to move horizontally in sync, ensuring the efficiency of the movement of the support member 23.

[0041] Example 2

[0042] As attached Figure 3 and attached Figure 4 As shown, this second embodiment is based on the first embodiment, with improvements made to the feeding mechanism 2 and the conveying table 11. The rest of the structure is the same as that of the first embodiment, and will not be described in detail here.

[0043] The feeding mechanism 2 also includes an airflow nozzle 28 that can spray compressed air. The airflow nozzle 28 is fixedly connected to the end of the push rod 27 that is inserted into the fixing groove 411. The length of the airflow nozzle 28 is less than the distance from the end of the push rod 27 to the fixing groove 411. The airflow nozzle 28 is used to clean the surface of the fixing groove 411 or the push rod 27 before insertion to prevent dust or impurities from accumulating and affecting the accuracy of insertion, thus extending the service life of the equipment. At the same time, the detachable snap-fit ​​connection makes it easier to clean, maintain or replace the airflow nozzle 28, improving the maintainability of the equipment.

[0044] At least two intelligent limit switches 14 are also installed on the conveyor table 11, and the intelligent limit switches 14 are electrically connected to the control system in the feeding mechanism 2. When the horizontal cylinder 21 or the vertical cylinder 24 drives the support 23 to approach the target position, the intelligent limit switch 14 sends a deceleration signal in advance, so that the cylinder moves slowly to the accurate position and then stops, thereby achieving more precise positioning control.

[0045] As attached Figure 5 and attached Figure 6As shown, a vertical limiting shaft 271 is fixed on the side of the push rod 27 facing the pusher 25. Limiting protrusions 272 are fixed on both sides of the limiting shaft 271. The limiting protrusions are arc-shaped, and a support spring 273 is fixed between the limiting protrusions 272 and the limiting shaft 271. The support spring 273 can ensure the extension and retraction of the limiting protrusions 272 in the horizontal direction.

[0046] The pusher 25 has multiple limiting grooves 251 for engaging the ends of the limiting shaft 271. The pusher 25 also has multiple protrusions 252 that communicate with the limiting grooves 251, and the limiting protrusions 272 engage with the protrusions 252 respectively. The pusher rod 27 can be engaged in different limiting grooves 251 through the limiting shaft 271. The limiting protrusions 272 and the protrusions 252 fix the limiting shaft 271, improving the versatility of the equipment.

[0047] Work process:

[0048] First, the pole-mounted circuit breaker 3 is conveyed to the conveyor table 11. The pole-mounted circuit breaker 3 is slidably connected to the conveyor slide rail 12. The transverse cylinder 21 is activated, and the output shaft of the transverse cylinder 21 pushes out, which drives the support member 23 to move along the transverse slide rail. After the output shaft of the transverse cylinder 21 has finished pushing out, the push rod 27 is aligned with the fixing groove 411 on the fixing plate 41. The longitudinal cylinder 24 is activated, and the output shaft of the longitudinal cylinder 24 pushes out, which drives the push member 25 to move towards the guide column 4. The push rod 27 will insert into the fixing groove 411. During the insertion process, the airflow on the push rod 27 sprays... The nozzle 28 cleans the fixed groove 411 to ensure that there are no accumulated impurities in the fixed groove 411 that would affect the insertion of the push rod 27. At this time, the transverse cylinder 21 is activated, and the output shaft of the transverse cylinder 21 will drive the support 23 to retract along the transverse slide rail. When the output shaft of the transverse cylinder 21 retracts, the push rod 27 will drive the pole-mounted circuit breaker 3 to the designated position. Then, the longitudinal cylinder 24 is activated, and the output shaft of the longitudinal cylinder 24 will drive the push rod 27 to move out of the fixed groove 411 and retract along the longitudinal guide rail 26, thus completing one feeding process of the pole-mounted circuit breaker 3.

[0049] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
