Description

Technical Field

[0001] This utility model belongs to the field of pole-mounted circuit breaker manufacturing, specifically relating to a cover mounting device for a pole-mounted circuit breaker mechanism box. Background Technology

[0002] As a critical power protection device in power transmission and distribution systems, pole-mounted circuit breakers use a mechanism box to house their core operating mechanisms. This mechanism box typically consists of an open enclosure and a matching cover. In the manufacturing process of vacuum circuit breakers, precisely assembling the cover to the opening of the mechanism box and securing it with screws is a necessary and frequently performed core process. Currently, this assembly process is mainly done manually: operators must manually pick up the cover, align it, and place it on the pre-positioned (usually by adjusting the enclosure so the opening faces upwards) mechanism box opening; then, they pick up the screws and use a manual or electric screwdriver to tighten them one by one into the corresponding screw holes on the cover and mechanism box. This manual operation is cumbersome and time-consuming, resulting in low production efficiency, high labor costs, and high worker workload, making it difficult to meet the urgent needs of modern production lines for high-efficiency, low-cost, and automated production.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0031] In this embodiment of the utility model, the structure of the cover mounting device for the pole-mounted circuit breaker mechanism box is as follows: Figures 1 to 6 As shown, it includes a screw feeding device 1, a circuit breaker positioning device 2, a cover feeding device 3, and a material transfer and locking device 4. The screw feeding device 1 is used to supply screws 11; the circuit breaker positioning device 2 is used to position the circuit breaker and is adapted to make the opening of the mechanism box 21 face upward; the cover feeding device 3 is used to supply the cover 30; the material transfer and locking device 4 is configured to: transfer the cover 30 from the cover feeding device 3 to the circuit breaker positioning device 2 and place the cover 30 on the opening of the mechanism box 21, and transfer the screws 11 from the screw feeding device 1 to the circuit breaker positioning device 2 to lock the cover 30. The cover installation device in this embodiment can realize the automatic transfer of the cover 30 to the mechanism box 21 and the locking of the screws 11, reducing manual intervention, thereby effectively improving production efficiency, reducing labor costs and labor intensity, and has good practicality and scalability.

[0032] The working process of this cover installation device is as follows: the circuit breaker positioning device 2 positions the circuit breaker and makes the opening of the mechanism box 21 face upward, preparing for the assembly of the cover; the material transfer and locking device 4 takes the cover 30 from the cover feeding device 3, then transfers the cover 30 and places it on the opening of the mechanism box 21 (the screw holes on the cover 30 are aligned with the screw holes on the mechanism box 21); then the material transfer and locking device 4 takes the screw 11 from the screw feeding device 1, transfers the screw 11 to the circuit breaker positioning device 2 and aligns it with the screw hole, and performs the screw tightening action to fix the cover 30 on the mechanism box 21, thereby completing the locking of the cover 30 and realizing the entire assembly process of the cover 30 (take cover → place → take screw → tighten), significantly reducing reliance on manual labor and completely eliminating the bottleneck of manual operation.

[0033] See Figure 3 As shown, the material transfer and locking device 4 includes an industrial robot 41, a mounting frame 42 fixed to the drive end of the industrial robot 41, a lid-collecting unit 43 fixed to the mounting frame 42, and a screw-clamping mechanism 44 and a screw-locking mechanism 45 fixed to the mounting frame 42. The industrial robot 41 drives the mounting frame 42 to move, thereby driving the lid-collecting unit 43, the screw-clamping mechanism 44, and the screw-locking mechanism 45 to transfer the lid 30. The lid-collecting unit 43 is used to collect the lid 30; the screw-clamping mechanism 44 is used to clamp the screw 11; and the screw-locking mechanism 45 is used to tighten the screw 11. The industrial robot 41 can be a multi-axis robot, such as a five-axis robot.

[0034] Continue reading Figure 3 The lid-collecting unit 43 includes a lifting drive unit 431 fixed on the mounting bracket 42 and a vacuum suction cup 432 driven up and down by the lifting drive unit 431. The vacuum suction cup 432 is connected to a vacuum generator. When collecting the lid 30, the lifting drive unit 431 drives the vacuum suction cup 432 to descend, and the vacuum generator generates negative pressure. When the vacuum suction cup 432 contacts the lid 30, it firmly adheres the lid 30 to the vacuum suction cup 432. Then, the lifting drive unit 431 drives the vacuum suction cup 432 to rise, thereby raising the lid 30. When the lid-collecting unit 43 is above the mechanism box, the lifting drive unit 431 drives the vacuum suction cup 432 to descend, so that the lid 30 closes on the mechanism box 21.

[0035] To improve the stability and adsorption effect of the lid suction unit 43 on the lid 30, the mounting frame 42 is equipped with a lifting drive unit 431 at each end of the lid 30. Each lifting drive unit 431 is equipped with two mounting plates 433, and these mounting plates 433 are equipped with at least two vacuum suction cups 432. Through the synergistic effect of multiple vacuum suction cups 432, the adsorption force can be distributed more evenly, ensuring a stable adsorption of the lid 30 and reducing the risk of detachment caused by uneven local pressure. At the same time, the design of multiple vacuum suction cups can increase the adsorption area, improve the stability of the lid and the safety of handling, thereby achieving more efficient and reliable operation.

[0036] Combination Figure 3 and Figure 4 As shown, the screw clamping mechanism 44 includes two opposing jaws 441 and an opening / closing drive unit 442 that drives the two jaws 441 to open and close. When the two jaws 441 are closed, a through cavity 443 is formed between them, and a screw clamping opening is formed at the lower end of the through cavity 443. The through cavity 443 is suitable for the bit rod 451 on the screw locking mechanism 45 to pass through. When clamping the screw 11, the two jaws 441 are driven to approach each other by the opening / closing drive unit 442 to clamp the screw 11. When tightening the screw, the bit rod 451 extends into the through cavity 443 and cooperates with the slot on the screw 11. Thus, when the screw locking mechanism 45 drives the bit rod 451 to rotate, it drives the screw 11 to perform a tightening action. The screw locking mechanism 45 can adopt existing technology, which will not be described in detail in this embodiment, such as the screw tightening mechanism structure in patent document CN119794782A. The opening / closing drive unit 442 is preferably a jaw cylinder.

[0037] Furthermore, the mounting bracket 42 is equipped with a vision sensor 420, which is connected to the control system of the box cover mounting device. The vision sensor 420 can monitor the position of the workpiece in real time and cooperate with the industrial robot for real-time adjustment to improve the accuracy of the identification of the box cover 30 and screw 11, thereby ensuring the accuracy of the operation. For example, the vision sensor 420 includes an industrial camera and a supplementary light. The supplementary light can compensate for the lighting of the industrial camera to improve the visual effect.

[0038] Combination Figure 1 and Figure 2 As shown, the screw feeding device 1 includes a screw vibrating plate 12, a conveying track 13 connected to the screw vibrating plate 12, and a screw sorting unit 14 disposed at the end of the conveying track 13. The screw vibrating plate 12 vibrates to arrange the screws 11 in an orderly manner in the conveying track 13 and conveys them forward. The screw sorting unit 14 controls a screw 11 at the end of the conveying track 13 to deviate from the end opening of the conveying track 13 so that it can be clamped by the screw clamping mechanism 44.

[0039] More specifically, the screw distribution unit 14 includes a distribution block 141 and a transverse drive cylinder 142 for driving the distribution block 141 to move laterally. The distribution block 141 is provided with a receiving groove 143 for accommodating a screw 11. During the distribution process, the receiving groove 143 is initially aligned with the end opening of the conveying track 13 and receives a screw 11 from the end of the conveying track 13. Then, the distribution block 141 moves to drive the screw 11 in the receiving groove 143 to deviate from the end opening of the conveying track 13 (at the same time, the distribution block 141 closes the end opening of the conveying track 13) so that the screw clamping mechanism 44 can clamp it.

[0040] like Figure 5 As shown, the box lid feeding device 3 includes a machine base 31, a box lid support 32 that is movably mounted on the machine base 31, a linear drive module 33 that drives the box lid support 32 to move up and down, a limiting frame 34 fixed on the machine base 31 and located on the side of the box lid support 32, and a photoelectric sensor 35 for detecting the height position of the box lid 30. The photoelectric sensor 35 can be mounted on the limiting frame 34, or a separate mounting frame can be provided for mounting the photoelectric sensor 35. During the supply of box lids 30, multiple box lids 30 are stacked on the box lid support 32, with the uppermost box lid 30 corresponding to the position of the photoelectric sensor 35. When the photoelectric sensor 35 senses that the uppermost box lid 30 has been removed, the linear drive module 33 drives the box lid support 32 to move upward, keeping the upper box lid 30 at the corresponding height position, so that the box lid picking unit 43 can pick it up. Preferably, the linear drive module 33 adopts a lead screw mechanism driven by a servo motor.

[0041] See Figure 6As shown, the circuit breaker positioning device 2 includes a positioning base 22, two fixed supports 23 that are rotatably mounted on the positioning base 22 and opposite to each other, and a rotary drive unit 24 that drives the fixed supports 23 to rotate. The fixed supports 23 are fixedly connected to the mechanism box 21 of the circuit breaker. The fixed supports 23 and the mechanism box 21 can be fixedly connected by fixing bolts. During the assembly of the circuit breaker, both ends of the mechanism box 21 are fixedly connected to the two fixed supports 23 respectively. The rotary drive unit 24 can drive the fixed supports 23 to rotate, thereby controlling the rotation of the mechanism box 21 to meet the needs of assembly production. The rotary drive unit 24 can be a motor. There is one rotary drive unit 24, which is fixedly connected to one of the fixed supports 23. The positioning seat 22 is further configured to include a base 221 and two support frames 222 oppositely disposed on the base 221. Two fixed brackets 23 are respectively mounted on the two support frames 222. The distance between the two support frames 222 is adjustable. In actual use, the distance between the two support frames 222 can be adjusted according to the size of the mechanism box 21 to ensure reliable fixation of the mechanism box 21. For example, one support frame 222 is fixedly connected to the base 221, and the other support frame 222 can be slidably mounted on the base 221. When the two support frames 222 are adjusted to a suitable distance, locking bolts can be used to lock the support frame 222.

[0042] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
