Description

Technical Field

[0001] This utility model belongs to the technical field of circuit breaker assembly equipment, specifically a copper and iron assembly structure for a moving contact assembly. Background Technology

[0002] Circuit breakers are key control devices in power systems, used to close, carry, and interrupt current. They can automatically cut off abnormal currents, prevent circuit faults from escalating, and protect the power grid and equipment safety. They are widely used in power, communication, transportation, construction and other fields to protect electrical equipment and power grid safety. With the development of technology, circuit breakers will become more intelligent and automated, improving their protection performance. Among them, the moving contact assembly is an important component of the circuit breaker.

[0003] A circuit breaker includes components such as a housing and a moving contact assembly. The moving contact assembly includes copper parts, copper wires, iron parts, torsion springs, plastic parts, and pins. The various parts are assembled using moving contact assembly equipment.

[0004] The existing moving contact assembly equipment has the following drawbacks: In the traditional assembly process, before the copper parts are assembled into the fixture, the copper wires that have been welded on one side often bend and deviate towards the top of the copper parts during subsequent operations due to the lack of effective sorting measures. When the iron parts are assembled, the copper wires often get stuck between the iron and copper parts, leading to assembly failure and seriously reducing the success rate of assembly and the yield of products. Therefore, in order to solve the above problems, a copper and iron parts assembly structure for moving contact assemblies is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing moving contact assembly equipment, a copper and iron assembly structure for moving contact assemblies is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The copper and iron parts assembly structure of the moving contact assembly of this utility model includes a worktable, on which an indexing plate is rotatably mounted. A copper part assembly mechanism and an iron part assembly mechanism are arranged around the indexing plate. An assembly fixture corresponding to the copper part assembly mechanism and the iron part assembly mechanism is arranged around the indexing plate. A copper wire pressing mechanism for moving copper wire is arranged between the copper part assembly mechanism and the iron part assembly mechanism. The copper wire pressing mechanism includes a moving device acting on the copper wire and a straightening device for straightening the copper part.

[0007] Preferably, the actuating device includes a first cylinder fixedly mounted on the workbench, and the working end of the first cylinder is fixedly equipped with a push plate for pushing the copper wire. The push plate has a V-shaped notch that matches the copper wire, and the edges of the V-shaped notch are all provided with arc-shaped chamfers.

[0008] Preferably, the bottom end of the push plate is five millimeters higher than the top end of the assembly fixture.

[0009] Preferably, the correction device includes a first slide cylinder fixedly mounted on the workbench, and the working end of the first slide cylinder is fitted with a positioning pin that mates with a hole on the copper part via an assembly frame.

[0010] Preferably, the copper component assembly mechanism includes a second slide cylinder fixedly mounted on the worktable, a third slide cylinder mounted on the working end of the second slide cylinder, and a first clamping cylinder for picking up and placing copper components mounted on the working end of the third slide cylinder.

[0011] Preferably, the iron part assembly mechanism includes a slide fixedly mounted on a workbench, a fourth slide cylinder slidably mounted on the slide, a second cylinder for driving the fourth slide cylinder to move fixedly mounted on one side of the slide, a fifth slide cylinder mounted on the working end of the fourth slide cylinder, a sixth slide cylinder mounted on the working end of the fifth slide cylinder, and a second clamping cylinder for picking up and placing iron parts mounted on the working end of the sixth slide cylinder.

[0012] Preferably, a detection mechanism for detecting whether there are copper parts in the assembly fixture is provided between the copper part assembly mechanism and the copper wire pressing mechanism. The detection mechanism includes a photoelectric sensor fixedly mounted on the worktable by a fixing frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. Optimized assembly effect by a toggle device: This utility model sets a toggle device between the copper part assembly mechanism and the iron part assembly mechanism. This is the key to improving the assembly quality. The toggle device can effectively push the copper wire to one side of the copper part before the iron part is assembled. The setting of the bottom end of the push plate being 5 mm higher than the top end of the assembly fixture makes the push plate closer to the bottom of the copper wire, which is conducive to the accurate entry of the copper wire into the V-shaped notch. This makes it more effective to push the copper wire to one side, avoiding the impact of improper copper wire position on the iron part assembly, and greatly improving the assembly success rate and product yield.

[0015] 2. The straightening device ensures assembly accuracy: The straightening device, through the precise matching of the positioning pin and the hole of the copper part, can effectively eliminate the positional deviation of the copper part and adjust the position of the copper part to an accurate state. This improves the assembly quality of the moving contact assembly, ensures the electrical connection performance and mechanical stability of the product, reduces product rework and scrap due to poor assembly, lowers production costs, and improves the economic benefits of the enterprise.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-3The present invention discloses a copper and iron component assembly structure for a moving contact assembly, comprising a worktable 1, on which an indexing plate 2 is rotatably mounted. A copper component assembly mechanism 3 and an iron component assembly mechanism 4 are arranged around the indexing plate 2. An assembly fixture 5 corresponding to the copper component assembly mechanism 3 and the iron component assembly mechanism 4 is arranged around the indexing plate 2. A copper wire pressing mechanism 6 for moving the copper wire 02 is arranged between the copper component assembly mechanism 3 and the iron component assembly mechanism 4. The copper wire pressing mechanism 6 includes a moving device 7 acting on the copper wire 02 and a straightening device 8 for straightening the copper component 01. The moving device 7 includes a first cylinder 701 fixedly mounted on the worktable 1, and the actuating end of the first cylinder 701 is fixedly mounted with a device for pushing... The push plate 702 for copper wire 02 has a V-shaped notch 703 that matches the copper wire 02. The edges of the V-shaped notch 703 are all chamfered. The bottom of the push plate 702 is 5 mm higher than the top of the assembly fixture 5. The copper part assembly mechanism 3 includes a second slide cylinder 301 fixedly mounted on the worktable 1. A third slide cylinder 302 is mounted on the actuating end of the second slide cylinder 301. A first clamping cylinder 303 for picking up and placing the copper part 01 is mounted on the actuating end of the third slide cylinder 302. The iron part assembly mechanism 4 includes a slide 401 fixedly mounted on the worktable 1. A fourth slide cylinder 402 is slidably mounted on the slide 401. A [missing information - likely a component or part] is fixedly mounted on one side of the slide 401. A second cylinder 403 is used to drive the fourth slide cylinder 402 to move. The working end of the fourth slide cylinder 402 is equipped with a fifth slide cylinder 404, and the working end of the fifth slide cylinder 404 is equipped with a sixth slide cylinder 405. The working end of the sixth slide cylinder 405 is equipped with a second clamping cylinder 406 for picking up and placing iron parts 03. During operation, the indexing plate 2 rotates precisely according to a preset angle and time interval under the drive of the drive device, transferring the assembly fixture 5 to the corresponding work positions of each working mechanism in sequence. When the copper part assembly mechanism 3 starts working, the working end of the second slide cylinder 301 installed on the worktable 1 moves linearly in the horizontal direction, driving the connected third slide cylinder 302 to move. The working end of cylinder 302 is connected to the first clamping cylinder 303. Through the coordinated action of these two sliding cylinders, the position of the first clamping cylinder 303 can be precisely adjusted in three-dimensional space. The first clamping cylinder 303 controls the opening and closing of the gripper through the air circuit, grabs the copper part 01 from the external feeding equipment, and accurately places it on the assembly fixture 5. Since copper wire 02 has been welded to one side of the copper part 01 by the external welding equipment before it is grabbed, the copper part 01 on the assembly fixture 5 at this time has copper wire 02. The indexing plate 2 rotates to transport the assembly fixture 5 with copper part 01 to the copper wire pressing mechanism 6. At this time, the air circuit of the first cylinder 701 is opened, and the compressed air pushes the piston to extend the piston rod, which drives the push plate 702 to move towards the copper wire 02.Because the bottom of the push plate 702 is 5 mm higher than the top of the assembly fixture 5, the push plate 702 can get closer to the bottom of the copper wire 02. Furthermore, the V-shaped notch 703 on the push plate 702 has a large opening. When the push plate 702 approaches the copper wire 02, the copper wire 02 will naturally fall into the V-shaped notch 703. As the push plate 702 continues to advance, it achieves a prying operation on the copper wire 02, pushing it to one side of the copper part 01 to prevent it from bending and deviating directly above the copper part 01. Then, the assembly fixture 5 moves towards the iron part assembly mechanism 4. The slide 401 fixed on the worktable 1 provides a linear motion track for the fourth slide cylinder 402. The second cylinder 403 drives the fourth slide cylinder 402 to move on the slide 401 and adjust its horizontal position through the extension and retraction of its piston rod. The fourth slide cylinder 402, the fifth slide cylinder 404, and the sixth slide cylinder 405 are connected in sequence. Through their respective air circuit-controlled extension and retraction actions, they coordinate to adjust the second clamping cylinder 40. Position 6 allows it to accurately pick up the iron part 03 from the external feeding equipment and place it onto the assembly fixture 5, which already contains the copper part 01 and has completed the copper wire 02 actuation, thus completing the assembly process of the iron part 03. The actuation device 7, located between the copper part assembly mechanism 3 and the iron part assembly mechanism 4, and the arc-shaped chamfer design of the V-shaped notch 703 on the push plate 702, reduces damage to the copper wire 02 when actuating it. The bottom of the push plate 702 is higher than the assembly fixture. The 5mm top section design allows the push plate 702 to get closer to the bottom of the copper wire 02, facilitating accurate entry of the copper wire 02 into the V-shaped notch 703. This more effectively pushes the copper wire 02 to one side, and the actuating device 7 can push the copper wire 02 to one side of the copper part 01 before the iron part 03 is assembled, preventing the copper wire 02 from getting stuck between the iron part 03 and the copper part 01. This ensures that the iron part 03 can be smoothly assembled onto the copper part 01, improving the assembly success rate and product yield.

[0025] Furthermore, the straightening device 8 includes a first sliding cylinder 801 fixedly mounted on the workbench 1. The working end of the first sliding cylinder 801 is fitted with a positioning pin 803 that mates with the hole 011 on the copper part 01 via an assembly frame 802. During operation, when the assembly fixture 5 containing the copper part 01 rotates with the indexing plate 2 to the position corresponding to the straightening device 8, the control system sends a control signal to the first sliding cylinder 801, causing the air passage of the first sliding cylinder 801 to be opened, driving the assembly frame 802 connected thereto to move synchronously. Since the positioning pin 803 is mounted on the assembly frame 802, as the assembly frame 802 moves, the positioning pin 803 gradually approaches the hole 011 on the copper part 01. When the positioning pin 803 is aligned with the hole 011, under the continuous thrust of the first sliding cylinder 801, the positioning pin 803... The copper part 01 is successfully inserted into the hole 011. If there is a positional deviation in the copper part 01 during the previous assembly process, the tight fit between the positioning pin 803 and the hole 011 will apply a corrective force to the copper part 01, adjusting its position until it reaches the accurate assembly position. After the correction is completed, the air path of the first slide cylinder 801 is reversed, and the piston rod retracts, causing the positioning pin 803 to exit from the hole 011 of the copper part 01, preparing for the next correction operation. The correction device 8, through the precise fit between the positioning pin 803 and the hole 011 of the copper part 01, can effectively eliminate these positional deviations, ensure the positional accuracy of the copper part 01 throughout the assembly process, improve the assembly quality of the moving contact assembly, reduce product rework and scrap due to poor assembly, reduce production costs, and improve the economic benefits of the enterprise.

[0026] Furthermore, a detection mechanism 9 is provided between the copper component assembly mechanism 3 and the copper wire pressing mechanism 6 to detect whether there is a copper component 01 in the assembly fixture 5. The detection mechanism 9 includes a photoelectric sensor 901 fixedly mounted on the workbench 1 by a fixing frame. During operation, the photoelectric sensor 901 operates on the principle of through-beam or reflection. When the assembly fixture 5 rotates with the indexing plate 2 and passes the photoelectric sensor 901, if there is no copper component 01 in the assembly fixture 5, the light emitted by the transmitter can directly pass through the space where the assembly fixture 5 is located and be received by the receiver. The receiver converts the received light signal into an electrical signal and transmits it to the control system. The control system judges that there is no copper component 01 in the assembly fixture 5 according to the preset logic. The control system will control the back-end assembly station not to work, to prevent invalid operations such as copper wire 02 manipulation and iron component 03 assembly when there is no copper component 01, to avoid resource waste and the production of defective products. If there is a copper component 01 in the assembly fixture 5, it will work normally, which improves the intelligence and reliability of the entire assembly system.
