Description

Technical Field

[0001] This utility model relates to relay assembly, specifically a relay copper bridge mounting device with copper bridge deflection angle guidance. Background Technology

[0002] In the circuit breaker manufacturing industry, the precise installation of copper bridge assemblies is a crucial step in ensuring the product's conductive stability and mechanical operational reliability. Currently, the copper bridge assembly process commonly used in the industry has the following technical shortcomings:

[0003] (1) Traditional automated installation equipment relies on precision positioning mechanisms to achieve the fit between the copper bridge and the base. Due to the mutual influence between the stamping tolerance of the copper bridge, the machining error of the base mounting groove, and the positioning accuracy of the equipment, axial misalignment of the positioning hole and the guide component is prone to occur during actual assembly. When multiple tolerances are superimposed, it often leads to unexpected deformation of the copper bridge or deviation of the installation path during the pressing process, resulting in a significant increase in the assembly failure rate.

[0004] (2) The existing assembly system lacks dynamic error compensation capabilities between different processes. When a slight deviation occurs in a certain step, subsequent processes cannot adaptively adjust the assembly parameters, causing the deviation to amplify step by step. This not only requires frequent interruptions of the production process for manual intervention, but also severely restricts the overall assembly efficiency in multi-station continuous operation scenarios.

[0005] To address the aforementioned issues, there is an urgent need for a copper bridge assembly solution with tolerance adaptability, which can reduce the dependence on the machining accuracy of components while ensuring the dimensional accuracy and functional reliability of the copper bridge after installation. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a relay copper bridge mounting device with copper bridge deflection angle guidance, which can dynamically compensate for assembly errors, reduce the dependence on the machining accuracy of parts, and improve the form and position accuracy and reliability of copper bridge installation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A relay copper bridge mounting device with a copper bridge offset angle guide includes a positioning component, a feeding component, and a filling component. The filling component receives the copper bridge provided by the feeding component and installs it into the circuit breaker housing via the positioning component. The positioning component includes a housing positioning seat for placing the relay housing, a pad located at the opening of the housing positioning seat for placing the relay housing, and an offset angle guide transition block mounted on the pad. The position of the offset angle guide transition block corresponds to the position of the circuit breaker housing for placing the copper bridge, and it is provided with a channel for the copper bridge to pass through. The channel gradually and smoothly narrows from one end of the filling component towards the end of the relay housing for placing the copper bridge, so as to guide the copper bridge as it passes through the channel.

[0009] As a further improvement of this utility model, at least a portion of the deflection angle guide transition block extends into the relay housing for engagement and positioning with the interior of the housing.

[0010] As a further improvement of this utility model, at least a portion of the deflection angle guide transition block is located at the opening edge of the relay housing for abutment positioning.

[0011] As a further improvement of this utility model, the filling component includes a clamping mechanism and a shaping mechanism; the clamping mechanism cooperates with the feeding component to clamp the copper bridge and fills the copper bridge into the relay housing through the deflection angle guide transition block; the shaping mechanism presses down and shapes the copper bridge after the clamping mechanism fills it.

[0012] As a further improvement of this utility model, the filling component also includes a fixed base, an actuator mounted on the fixed base, and a slide connected to the fixed base; the shaping mechanism and the clamping mechanism are both located on the slide, and the actuator drives the slide to slide on the fixed base, and the position of the clamping mechanism or the shaping mechanism is switched to correspond with the position of the deflection angle guide transition block by the sliding of the slide.

[0013] As a further improvement of this utility model, the clamping mechanism includes an actuator two, a gripper, and an auxiliary component; the actuator two drives the gripper and the auxiliary component to move synchronously to move closer to or further away from the filling component or the deflection angle guide transition block; the gripper is used to clamp the copper bridge, and the auxiliary component is used to cooperate with the gripper to abut and position the copper bridge.

[0014] As a further improvement of this utility model, the shaping mechanism includes an actuator three and several push rods; the actuator three drives the several push rods to move synchronously into or out of the channel of the deflection angle guide transition block, and when the several push rods enter the channel of the deflection angle guide transition block, they abut against the copper bridge and press the copper bridge into place.

[0015] As a further improvement of this utility model, the top rod and the corresponding relay housing of the channel are adapted to fit the size of one end of the copper bridge, so as to stably press the copper bridge into place.

[0016] As a further improvement of this utility model, the actuator two is a pneumatic push rod or a hydraulic push rod.

[0017] As a further improvement of this utility model, the actuator three is a pneumatic push rod or a hydraulic push rod.

[0018] The beneficial effects of this utility model are as follows: Through the channel design of the deflection angle guide transition block, the copper bridge is guided by the gradually narrowing channel during installation, which automatically corrects the offset, effectively compensates for the positioning deviation caused by the tolerance, and avoids deformation of the copper bridge or deviation from the path.

[0029] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0030] Reference Figure 1-9As shown, the relay copper bridge mounting device with copper bridge deflection angle guidance in this embodiment includes a positioning component 1, a feeding component, and a filling component 3. The filling component 3 obtains the copper bridge 4 provided by the feeding component and installs it into the circuit breaker housing through the positioning component 1. The positioning component 1 includes a housing positioning seat 11 for placing the relay housing, a pad 12 located at the opening of the housing positioning seat 11 for placing the relay housing, and a deflection angle guiding transition block 13 installed on the pad 12. The position of the deflection angle guiding transition block 13 corresponds to the position of the circuit breaker housing for placing the copper bridge 4, and is provided with a channel 131 for the copper bridge 4 to pass through. The channel 131 gradually and smoothly narrows from one end of the filling component 3 toward the end of the relay housing for placing the copper bridge 4, so as to guide the copper bridge 4 when it passes through the channel 131.

[0031] The feeding assembly transports the copper bridge 4 to the position of the filling assembly 3. The filling assembly 3 pushes the copper bridge 4 into the relay housing on the housing positioning seat 11 through the channel 131 of the offset guide transition block 13. The tapered structure of the channel 131 applies radial constraint to the copper bridge 4 during its movement, guiding the copper bridge 4 along a preset path into the installation position, and can dynamically compensate for the offset caused by machining tolerances. The pad 12 can be fixedly connected to the offset guide transition block 13 by bolts or integrally formed. The offset guide transition block 13 can be composed of two parts spliced ​​together, and the splice is fitted and inserted through a dovetail keyway. The feeding assembly is preferably a structure that can be conveyed in a fixed posture, allowing the copper bridge 4 to be conveyed in a fixed posture, which is convenient for the filling assembly 3 to obtain. This structure is prior art and will not be described in detail here.

[0032] Reference Figure 1 and 2 In the scheme shown, the pad 12 and the housing positioning seat 11 are separate structures. The housing positioning seat 11 can be installed on a conveyor belt and move back and forth, which makes it convenient for manual or mechanical placement of the relay housing in the housing positioning seat 11. When the housing positioning seat 11 is below the pad 12, the pad 12 can move up and down by a cylinder. Moving downward can bring the deflection angle guide transition block 13 into the relay housing, and moving upward can leave the relay housing.

[0033] In a preferred embodiment, at least a portion of the deflection angle guide transition block 13 extends into the relay housing for engagement and positioning with the interior of the housing. (Refer to...) Figure 7 The position C in the diagram is shown.

[0034] After the angled guide transition block 13 is inserted into the relay housing, its outer contour contacts the inside of the relay housing, stabilizing the relay housing and making its state more stable, thus avoiding problems such as tilting or warping. This abutment structure, combined with the guiding function of the channel 131, forms a dual positioning mechanism, improving the stability of the installation path of the copper bridge 4.

[0035] In a further configuration, at least a portion of the deflection angle guide transition block 13 is positioned and abutted against the edge of the opening in the relay housing. (Refer to...) Figure 7 The position D in the diagram is shown.

[0036] The edge abutment structure of the offset angle guide transition block 13 can further stabilize the state of the relay housing and prevent misalignment between the channel 131 and the relay housing installation position due to initial alignment deviation. Combined with the above-mentioned internal abutment, a multi-level positioning method from the outside to the inside is formed, improving the assembly fault tolerance rate.

[0037] As an optional solution to further improve the assembly effect of the copper bridge 4, the filling component 3 includes a clamping mechanism 31 and a shaping mechanism 32; the clamping mechanism 31 cooperates with the feeding component to clamp the copper bridge 4 and fills the copper bridge 4 into the relay housing through the deflection angle guide transition block 13; the shaping mechanism 32 presses down and shapes the copper bridge 4 after the clamping mechanism 31 fills the copper bridge 4.

[0038] The clamping mechanism 31 grips the copper bridge 4, making its state more stable during transport. After filling, the top rod 322 of the shaping mechanism 32 applies pressure to the copper bridge 4 to eliminate warping or tilting caused by assembly gaps. The two work together to achieve continuous "clamping-filling-shaping" actions, improving assembly efficiency and helping to increase the pass rate.

[0039] In the specific scheme, the filling component 3 also includes a fixed base 33, an actuator 34 mounted on the fixed base 33, and a slide 35 slidably connected to the fixed base 33; the shaping mechanism 32 and the clamping mechanism 31 are both located on the slide 35, and the actuator 34 drives the slide 35 to slide on the fixed base 33, and the sliding of the slide 35 switches the position of the clamping mechanism 31 or the shaping mechanism 32 to correspond to the position of the deflection angle guide transition block 13.

[0040] Actuator 34 drives slide 35 to slide along fixed base 33, causing clamping mechanism 31 and shaping mechanism 32 to alternately align with offset angle guide transition block 13. For example, when slide 35 moves, clamping mechanism 31 first aligns with offset angle guide transition block 13 to fill copper bridge 4, and then slide 35 resets to allow shaping mechanism 32 to align with offset angle guide transition block 13 to press copper bridge 4. This design achieves multi-station collaboration through a single actuator, simplifying the mechanical structure and reducing control complexity. Furthermore, during the pressing of copper bridge 4 by shaping mechanism 32, clamping mechanism 31 can also grip copper bridge 4, further improving work efficiency.

[0041] As an optional embodiment of the clamping mechanism 31, the clamping mechanism 31 includes an actuator 311, a gripper 312, and an auxiliary component 313; the actuator 311 drives the gripper 312 and the auxiliary component 313 to move synchronously to move closer to or further away from the filling component 3 or the deflection angle guide transition block 13; the gripper 312 is used to clamp the copper bridge 4, and the auxiliary component 313 is used to cooperate with the gripper 312 to abut and position the copper bridge 4.

[0042] Actuator 2 311 pushes gripper 312 closer to or further away from copper bridge 4. After approaching copper bridge 4, the following two schemes can be implemented: 1. Auxiliary component 313 abuts against copper bridge 4, and after the state of copper bridge 4 is stabilized, gripper 312 clamps copper bridge 4; 2. After gripper 312 clamps copper bridge 4, auxiliary component 313 further stabilizes its state by abutting against copper bridge 4, which has a certain corrective effect.

[0043] The synchronized movement of the gripper 312 and the auxiliary component 313 maintains a stable posture during the clamping process of the copper bridge 4, avoiding tilting caused by unilateral force.

[0044] As an optional embodiment of the shaping mechanism 32, the shaping mechanism 32 includes an actuator 321 and a plurality of push rods 322; the actuator 321 drives the plurality of push rods 322 to move synchronously into or out of the channel 131 of the deflection angle guide transition block 13; when the plurality of push rods 322 enter the channel 131 of the deflection angle guide transition block 13, they abut against the copper bridge 4 and press the copper bridge 4 into place.

[0045] After the push rod 322 enters the channel 131 of the deflection angle guide transition block 13, its end contacts the surface of the copper bridge 4 and applies uniform pressure, forcing the copper bridge 4 to be fully embedded in the mounting slot of the relay housing. The synchronous movement of the push rod 322 is achieved by the drive of the actuator 321. For example, multiple push rods 322 are mounted on a mounting plate, and the mounting plate is connected to the actuator 321 to achieve synchronous drive, avoiding local deformation of the copper bridge 4 caused by single-point pressure.

[0046] In the specific solution, the top rod 322 and the channel 131 are matched in size to the relay housing for placing one end of the copper bridge 4, so as to stably press the copper bridge 4 into place.

[0047] The push rod 322 can be slightly smaller than the size of the channel 131, so that the whole is in a fit state, ensuring that the copper bridge 4 fits tightly against the groove wall when pressed, while avoiding friction between the push rod 322 and the channel 131.

[0048] Based on the above scheme, actuator 1 34, actuator 2 311, and actuator 3 321 can all be implemented using pneumatic push rods or hydraulic push rods. These two schemes have a buffering effect and can avoid damage to components caused by rigid collisions. Figure 1 , 2 For clarity, actuators 311 (second) and 321 (third) are not yet connected to their corresponding positions. (See reference...) Figure 2 As shown, the lower ends of actuator 2 311 and actuator 3 321 can continue to connect downwards to the corresponding connecting rods to complete the assembly.

[0049] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
