[0002] A circuit breaker is a combination switch that automatically disconnects a circuit to provide protection when a fault occurs.

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0026] Example 1: like Figures 1-2As shown in the figure, an embodiment of the present invention provides a circuit breaker copper sheet processing device, including a conventional workbench 1 in the art; a support mechanism 2 and a feeding mechanism 3 are mounted side by side on the upper surface of the workbench 1; a punching mechanism 4 and a bending mechanism 5 are mounted side by side on the support mechanism 2; a copper sheet transfer mechanism 6 is installed between the punching mechanism 4 and the bending mechanism 5; the copper sheet transfer mechanism 6 can transfer the copper sheet on the punching mechanism 4 to the bending mechanism 5; a pushing mechanism 7 corresponding to the punching mechanism 4 is installed on the feeding mechanism 3; the pushing mechanism 7 can push the copper sheet on the feeding mechanism 3 to the punching mechanism 4.

[0027] When punching and bending of circuit breaker copper sheets are required, the worker first places multiple copper sheets to be processed on the feeding mechanism 3. The feeding mechanism 3 then sequentially conveys the copper sheets to the positions corresponding to the pushing mechanism 7. Next, the pushing mechanism 7 pushes the single copper sheet located on the feeding mechanism 3 to the punching mechanism 4. The punching mechanism 4 then punches the copper sheet. After punching, the copper sheet transfer mechanism 6 picks up the punched copper sheet located on the punching mechanism 4 and transfers it to the bending mechanism 5. The bending mechanism 5 then bends the copper sheet to make it into a finished shape that meets the assembly requirements of the circuit breaker. Finally, the copper sheet transfer mechanism 6 removes and moves out all the processed copper sheets from the bending mechanism 5, thus completing a complete work cycle. This effectively replaces the traditional manual step-by-step operation, significantly reduces the labor intensity of workers, and because each process is carried out continuously on the same device, there is no need to transfer materials between different devices, which greatly shortens the processing cycle and thus effectively improves the overall processing efficiency of copper sheets.

[0028] Among them, such as Figure 1 As shown, to achieve automatic collection of finished copper sheets and avoid manual handling, a collection box 8 with an open top is horizontally placed on the upper surface of the workbench 1; the collection box 8 is located on one side of the support mechanism 2; the copper sheet transfer mechanism 6 can transfer the copper sheets from the bending mechanism 5 into the collection box 8. After the bending mechanism 5 completes the bending process on the copper sheet, the copper sheet transfer mechanism 6 can transfer the copper sheets from the bending mechanism 5 into the collection box 8, realizing automatic unloading and collection of finished products without manual intervention, further reducing labor intensity and improving the automation level of the entire processing flow.

[0029] Example 2: Based on Example 1, as follows Figures 2-4As shown, in order to provide a structurally stable mounting base for the punching mechanism 4 and the bending mechanism 5, the support mechanism 2 includes a base plate 201 horizontally arranged above the workbench 1 and a column 202 vertically bolted to the upper surface of the workbench 1; the opposite sides of the base plate 201 are respectively bolted to the upper surface of the workbench 1 by mounting blocks 203; a bearing plate 204 is horizontally bolted to the upper end of the column 202; the bearing plate 204 is arranged directly above the base plate 201.

[0030] Among them, such as Figures 3-4 As shown, to achieve the punching process of copper sheets, a waste discharge hole 205 is vertically opened on the upper surface of the substrate 201; the punching mechanism 4 includes a punching die 401 bolted to the upper surface of the substrate 201 and a first cylinder 402 vertically bolted to the upper surface of the support plate 204; the punching die 401 is a conventional component in the art; the punching die 401 is positioned directly above the waste discharge hole 205; the output end of the first cylinder 402 slides through the support plate 204 and is vertically bolted to a punching post 403 corresponding to the punching die 401. When the first cylinder 402 drives the punching post 403 to punch downwards quickly, the copper sheet is punched with holes in cooperation with the punching die 401, and the generated waste material falls directly through the waste discharge hole 205 below under the action of gravity, without remaining in the punching die 401, thereby avoiding interference from the waste material to the subsequent placement of copper sheets and ensuring the continuity and stability of the punching process.

[0031] In addition, such as Figure 3 and Figure 6As shown, in order to position the copper sheet during punching, a connecting plate 404 is horizontally bolted to the output end of the first cylinder 402; the connecting plate 404 is positioned above the punching post 403; a pair of guide posts 405 are vertically slidably inserted side by side on the connecting plate 404; the lower ends of the two guide posts 405 are connected by a horizontally positioned positioning plate 406; a first spring 407 is sleeved on the outer periphery of each of the two guide posts 405; the upper and lower ends of the two first springs 407 are respectively screwed to the connecting plate 404 and the positioning plate 406; a receiving hole 408 is vertically opened on the upper surface of the positioning plate 406 and is coaxially arranged with the punching post 403; the punching post 403 can be clearance-fitted into the receiving hole 408. When the first cylinder 402 drives the connecting piece 404 to move downward, the connecting piece 404 first moves downward along with the positioning piece 406 via the first spring 407, so that the positioning piece 406 contacts the upper surface of the copper sheet before the punching post 403. As the connecting piece 404 continues to press down, the first spring 407 is compressed, and its elastic force gradually increases, thereby applying a gradually increasing preload to the copper sheet through the positioning piece 406, firmly pressing the copper sheet onto the punching die 401. After the positioning piece 406 presses the copper sheet, the connecting piece 404... 4. Continuing downwards, the punching post 403 passes through the receiving hole 408 and extends out of the lower surface of the positioning piece 406 to punch the fixed copper sheet. Since the copper sheet has been reliably fixed before punching, it effectively prevents the copper sheet from moving due to force during punching, significantly improving the accuracy of the punching position and the cross-sectional quality of the hole wall. After punching is completed, the first cylinder 402 retracts, the first spring 407 returns to its deformation, and the positioning piece 406 quickly detaches from the surface of the copper sheet with the assistance of the spring force, avoiding the copper sheet being pulled up due to adhesion and ensuring the smooth flow of the process.

[0032] Among them, such as Figures 3-4 As shown, to achieve the bending process of the punched copper sheet, the bending mechanism 5 includes a bending die 501 bolted to the upper surface of the substrate 201 and a second cylinder 502 bolted to the upper surface of the support plate 204. The bending die 501 is a conventional component in the art. The bending die 501 is disposed between the column 202 and the punching die 401. The output end of the second cylinder 502 slides through the support plate 204 and is bolted to a bending block 503 corresponding to the bending die 501. When the second cylinder 502 drives the bending block 503 to move downward rapidly, the bending block 503 and the bending die 501 cooperate with each other to punch the flat copper sheet located between them into a preset bending angle, thereby completing the bending process.

[0033] Example 3: Based on Example 2, as follows Figures 2-4As shown, in order to achieve non-destructive transfer of copper sheets between punching die 401 and bending die 501, the copper sheet transfer mechanism 6 includes a rotary drive assembly mounted on the substrate 201 and a lifting drive assembly mounted on the support plate 204; a rotary cylinder 601 connected to the lifting drive assembly is vertically connected to the rotary drive assembly; the rotary drive assembly can drive the rotary cylinder 601 to rotate vertically, and the lifting drive assembly can drive the rotary cylinder 601 to move up and down; the rotary cylinder 601 is disposed between the punching die 401 and the bending die 501; a movable strip 602 is horizontally bolted to the lower end of the rotary cylinder 601; a pair of conventional negative pressure suction nozzles 603 are vertically connected side by side at both ends of the movable strip 602.

[0034] When it is necessary to transfer the copper sheet on the punching die 401 to the bending die 501, the lifting drive assembly first drives the rotating cylinder 601 downward, causing the pair of negative pressure suction nozzles 603 located at the end of the movable strip 602 near the punching die 401 to descend and contact the upper surface of the punched copper sheet on the punching die 401. The negative pressure suction nozzles 603 are connected to an external negative pressure air source, generating suction to hold the copper sheet. Then, the lifting drive assembly drives the rotating cylinder 601 upward, raising the held copper sheet to a height higher than the punching die 401 and the bending die 501. Finally, the rotation drive assembly drives the rotating cylinder 601 to rotate, causing the movable strip 602 to rotate around the rotating cylinder 601. The axis of component 1 rotates in the horizontal plane, causing the end with the copper sheet adsorbed to rotate from directly above the punching die 401 to directly above the bending die 501. Then, the lifting drive component drives the rotating cylinder 601 to move downward again, accurately placing the copper sheet on the bending die 501. The negative pressure suction nozzle 603 disconnects the air source, releasing the copper sheet. Finally, the lifting drive component and the rotating drive component reset in sequence, completing a complete transfer cycle. The copper sheet is transferred by adsorption through the negative pressure suction nozzle 603. Since there is no rigid clamping with the copper sheet, scratching the surface of the copper sheet is avoided. At the same time, the rotary transfer path saves more horizontal space than linear reciprocating motion, making the structure of the entire device more compact.

[0035] Among them, such as Figure 3 and Figure 7As shown, in order to drive the movable slat 602 to achieve the above-mentioned rotational action, the rotational drive assembly includes a first geared motor 604 vertically bolted to the upper surface of the base plate 201 and a splined shaft 605 vertically rotatably connected to the upper surface of the base plate 201; the output shaft of the first geared motor 604 is keyed to a first gear 606; a second gear 607 meshes with the first gear 606; the second gear 607 is keyed to the lower end of the splined shaft 605; the rotating cylinder 601 is slidably sleeved on the outer periphery of the splined shaft 605; the rotating cylinder 601 can rotate synchronously with the splined shaft 605 and can also slide axially on the splined shaft 605. Because the spline shaft 605 can transmit torque and allow axial sliding, its cooperation with the rotating cylinder 601 perfectly integrates rotational and lifting motions. When the first reduction motor 604 starts, its output shaft drives the first gear 606 to rotate, which in turn drives the meshing second gear 607 to rotate, thereby causing the spline shaft 605 to rotate around its own axis. The rotation of the spline shaft 605 is directly and precisely transmitted to the rotating cylinder 601, which in turn drives the movable strip 602 to rotate in the horizontal plane. The gear meshing transmission has a precise transmission ratio and accurate positioning, ensuring that the movable strip 602 always stops precisely above the punching and bending stations, providing positional assurance for subsequent lifting, picking, and placement actions.

[0036] Among them, such as Figure 3 and Figure 7 As shown, in order to drive the rotating cylinder 601 to rise and fall in a simple and responsive manner, the lifting drive assembly includes an electromagnet 608 vertically screwed onto the support plate 204 and a permanent magnet 609 horizontally screwed onto the upper end face of the rotating cylinder 601; the permanent magnet 609 is located directly below the electromagnet 608; a limit block 610 is located below the permanent magnet 609; the limit block 610 is screwed onto the circumferential side wall of the spline shaft 605; the limit block 610 is located below the rotating cylinder 601. When electromagnet 608 is energized in the forward direction, it generates a magnetic force that attracts the permanent magnet 609. This attraction overcomes the gravity of components such as the rotating cylinder 601 and the movable plate 602, pulling the permanent magnet 609 upward. This causes the rotating cylinder 601 to slide upward along the spline shaft 605, achieving an upward movement. When electromagnet 608 is energized in the reverse direction, it generates a magnetic force opposite to that of the permanent magnet 609, causing the permanent magnet 609 to move downward. This causes the rotating cylinder 601 and the movable plate 602 to slide downward along the spline shaft 605 until the lower end face of the rotating cylinder 601 abuts against the limit block 610, achieving a downward movement. By controlling the on and off states of electromagnet 608, the lifting and lowering of the rotating cylinder 601 can be quickly controlled. The response speed is fast, and there is no need for a complex transmission mechanism, which simplifies the device structure and reduces manufacturing costs.

[0037] In addition, such as Figure 7As shown, to prevent the negative pressure suction nozzle 603 from damaging the copper sheet due to excessive impact force when it descends and contacts the copper sheet, and to ensure a tight fit between the nozzle and the copper sheet surface for reliable adsorption, the negative pressure suction nozzle 603 is slidably inserted onto the movable strip 602. A retaining ring 611 is fixedly sleeved on the outer periphery of the lower end of the negative pressure suction nozzle 603. The upper surface of the retaining ring 611 is connected to the lower surface of the movable strip 602 by a second spring 612. When the movable strip 602 descends to the point where the negative pressure suction nozzle 603 contacts the copper sheet, if the movable strip 602 continues to descend, it will slide downward relative to the negative pressure suction nozzle 603, thereby compressing the second spring 612. The elastic force generated by the compressed second spring 612 reacts to the negative pressure suction nozzle 603, causing it to adhere to the copper sheet surface with a flexible pressure, rather than a rigid impact. This serves as a buffer, protecting the copper sheet surface from being damaged by pressure. On the other hand, under the continuous action of the spring force, the gap between the suction port of the negative pressure nozzle 603 and the copper sheet surface is compressed to a minimum, improving the sealing and reliability of the adsorption and preventing the copper sheet from falling off during the transfer process due to weak adsorption.

[0038] Example 4: Based on Example 3, as follows Figure 3 and Figure 5 As shown, in order to achieve orderly and continuous supply of copper sheets to be processed, the feeding mechanism 3 includes a pair of horizontally bolted beams 301 connected side by side to the upper surface of the workbench 1; a pair of rollers 302 are rotatably connected side by side between the two beams 301; one end of one roller 302 is coaxially fixed to the output shaft of a second reduction motor 303; the second reduction motor 303 is bolted to one beam 301; the two rollers 302 are connected by a conveyor belt 304; multiple spacers 305 are horizontally bonded side by side on the working surface of the conveyor belt 304; the length direction of the multiple spacers 305 is perpendicular to the length direction of the beams 301; the upper surface of the other beam 301 is provided with a feeding port 306 corresponding to the punching die 401. Workers need to place copper sheets one by one on the conveyor belt 304 between two adjacent partitions 305. As the conveyor belt 304 moves forward, the copper sheets are transported forward neatly and at equal intervals, realizing automatic queuing and feeding of the copper sheets to be processed. This avoids the copper sheets from stacking or shifting during the transport process and ensures that the subsequent pushing mechanism 7 can accurately grab each copper sheet.

[0039] Among them, such as Figure 5As shown, in order to push the copper sheet conveyed by the feeding mechanism 3 onto the punching die 401, the pushing mechanism 7 includes a support plate 701 vertically bolted to a crossbeam 301; a third cylinder 702 is horizontally bolted to one side of the support plate 701 away from the conveyor belt 304; the output end of the third cylinder 702 slides through the support plate 701 and is bolted to a pushing block 703. When the feeding mechanism 3 conveys a single copper sheet to the position corresponding to the feeding port 306, the conveyor belt 304 stops operating. Then, the third cylinder 702 pushes the pushing block 703 toward the conveyor belt 304, and the pushing block 703 pushes the copper sheet off the conveyor belt 304, so that it passes through the feeding port 306 and slides to the predetermined position on the punching die 401. After the pushing is completed, the third cylinder 702 drives the pushing block 703 to retract and reset, ensuring the feeding effect of the copper sheet.

[0040] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
