Description

Technical Field

[0001] This utility model relates to the field of relay assembly technology, specifically to a novel iron core hinge mechanism. Background Technology

[0002] In the field of modern electronic control technology, relays, as a key electronic control device, are widely used in various automatic control circuit systems. The iron core, yoke, and coil are important components of a relay. During relay manufacturing, the fit between the yoke and the iron core is crucial; they must be hinged together to form an integrated structure to ensure the effective transmission and concentration of electromagnetic force. Currently, the commonly used iron core hinge process involves first inserting the iron core into the coil, combining the iron core, coil, and yoke to form the workpiece to be hinged. Then, a specialized iron core hinge mechanism applies downward pressure to the iron core, causing its bottom end to protrude from the coil and firmly press into the pre-set insertion hole of the yoke, ultimately tightly bonding the yoke, coil, and iron core into a single unit. However, existing iron core hinge mechanisms have some problems that urgently need to be solved in practical applications.

[0003] The existing iron-core hinge mechanism requires an additional robotic arm to complete the hinge operation process. During operation, the robotic arm first needs to transport the workpieces to be hinged one by one from the conveyor belt to the working position of the iron-core hinge mechanism. After the iron-core hinge mechanism completes the hinge operation, the robotic arm needs to transport the hinged workpieces back to the conveyor belt for the next process. This operation method has significant drawbacks. On the one hand, the introduction of the robotic arm increases the complexity and cost of the equipment; on the other hand, the entire operation process requires the robotic arm to frequently travel back and forth between the iron-core hinge mechanism and the conveyor belt, which not only reduces production efficiency but also increases the uncertainty and risk of failure in the production process.

[0004] Given the drawbacks of the existing iron core hinge mechanism, it is particularly necessary to develop a new type of iron core hinge mechanism. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This invention provides a novel iron core hinge mechanism, which can at least solve the technical problem of how to improve production efficiency.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel iron core hinge mechanism, comprising:

[0009] frame;

[0010] The workbench is mounted on the frame and has a sliding channel for docking and connecting with an external conveying mechanism. The sliding channel has an articulated station.

[0011] The tooling is slidably connected to the sliding channel of the worktable and is used to accommodate and limit the workpiece to be hinged.

[0012] The positioning module is located on the worktable and is positioned relative to the hinge station. The positioning module is used to position the workpiece to be hinged at the hinge station.

[0013] The hinge module is mounted on the frame and located above the hinge station. The hinge module is used to press down on the workpiece to be hinged at the hinge station to press the iron core of the workpiece into the yoke.

[0014] Further configuration of the aforementioned workbench includes:

[0015] The movable table can be slidably mounted on the frame and has a first channel for sliding connection with the tooling. The sliding trajectory of the movable table includes a first position and a second position arranged vertically. An elastic element is provided between the movable table and the frame. The elastic element has an elastic force that drives the movable table to slide toward the first position. The positioning module is mounted on the movable table, and the hinge station is located on the first channel.

[0016] Two fixed platforms are fixed on the frame and are located on both sides of the movable platform. The fixed platforms are provided with a second channel for sliding connection with the tooling.

[0017] When the platform is in the first position, the positioning module opens both ends of the first channel, and the two ends of the first channel respectively connect and connect with the two second channels to form a sliding channel; when the platform is in the second position, the positioning module blocks both ends of the first channel, and the first and second channels are completely staggered.

[0018] Further configuration of the aforementioned workbench includes:

[0019] The movable platform can be slidably mounted on the frame along the vertical direction and is provided with a first channel. The first channel is configured as a sliding channel. The sliding trajectory of the movable platform includes a first position and a second position arranged vertically. An elastic element is provided between the movable platform and the frame. The elastic element has an elastic force that drives the movable platform to slide toward the first position. The positioning module is located on the movable platform.

[0020] When the platform is in the first position, the positioning module opens both ends of the first channel, and the sliding channel connects with and is linked to the external conveying mechanism; when the platform is in the second position, the positioning module blocks both ends of the first channel, and the sliding channel is staggered from the external conveying mechanism.

[0021] Further configuration of the aforementioned positioning module includes:

[0022] Two positioning blocks are respectively located on both sides of the movable platform. Each of the two positioning blocks has a limiting groove on the side facing each other, and a limiting space is formed between the two limiting grooves.

[0023] The positioning block drive assembly is located on the movable platform and is connected to the two positioning blocks in a transmission manner. The positioning block drive assembly is used to drive the two positioning blocks to move closer to each other or further away from each other along a first direction. The first direction is perpendicular to both the extension direction of the sliding channel and the vertical direction.

[0024] Further configuration: the aforementioned hinge module includes a pressure column and a pressure column drive. The pressure column is positioned above the hinge station and is positioned opposite to the iron core position on the hinge station. The pressure column drive is mounted on the frame and is connected to the pressure column for transmission. The pressure column drive is used to drive the pressure column to move toward or away from the hinge station to press the iron core into the yoke's insertion port.

[0025] In a further configuration, the aforementioned hinge module also includes a pressure block, which is positioned opposite to the tooling and is connected to the pressure column drive component. The pressure column drive component is used to drive the pressure column and the pressure block to move together toward or away from the hinge position.

[0026] Furthermore, the aforementioned hinge module also includes a support column, which is fixed on the frame and positioned opposite to the pressure column. Both the worktable and the tooling are provided with clearance channels for the support column to pass through.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the novel iron core hinge mechanism provided by this utility model has the following characteristics:

[0029] Beneficial effects:

[0030] When using the novel iron core hinge mechanism provided by this utility model, firstly, a tooling with a workpiece to be hinged is slidably input into the hinge station along the sliding channel by an external conveyor belt or other conveying mechanism; then, the positioning module fixes the workpiece to be hinged in the hinge station to prevent the workpiece from moving during the subsequent hinge process, thus affecting the hinge accuracy and quality; finally, the hinge module presses down on the workpiece to be hinged in the hinge station to press the iron core of the workpiece into the yoke. After the hinge is completed, the hinge module and the positioning module release the hinged workpiece in the hinge station together, and the external conveying mechanism inputs the next tooling with a workpiece to be hinged into the hinge station, thereby moving the hinged workpiece in the hinge station out of the hinge station. This process is repeated continuously to achieve continuous hinge of the workpiece to be hinged. As can be seen, compared with the existing technology, the input and output ends of the sliding channel of this utility model can be directly connected to the external conveying mechanism, receive the workpiece to be hinged conveyed by the external conveying mechanism, and send the hinged workpiece to the external conveying mechanism. The material is directly fed by the external conveying mechanism, eliminating the need for additional robotic arms, greatly simplifying the operation process, reducing equipment costs, and effectively improving production efficiency. It also reduces the uncertainty and failure risk in the production process, thereby meeting the needs of the relay manufacturing industry for efficient and stable production.

[0042] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] This invention provides a novel iron core hinge mechanism to address the problem of improving production efficiency.

[0044] See Figure 1 As shown, Figure 1 The figure shows a perspective view of the novel iron core hinge mechanism in the embodiment. The novel iron core hinge mechanism includes a frame 1, a workbench 2, a tooling 3, a positioning module 4, and a hinge module 5.

[0045] The worktable 2 is mounted on the frame 1 and has a sliding channel 21 for docking and communicating with an external conveying mechanism. The sliding channel 21 is provided with a hinged station 22.

[0046] The tooling 3 is slidably connected to the sliding channel 21 of the worktable 2. The tooling 3 is used to accommodate and limit the workpiece 8 to be hinged.

[0047] The positioning module 4 is installed on the worktable 2 and is positioned relative to the hinge station 22. The positioning module 4 is used to position the workpiece 8 to be hinged on the hinge station 22.

[0048] The hinge module 5 is mounted on the frame 1 and located above the hinge station 22. The hinge module 5 is used to press down the workpiece 8 to be hinged on the hinge station 22 so as to press the iron core 81 of the workpiece 8 to be hinged into the yoke 83.

[0049] When using the novel iron core hinge mechanism described above, firstly, a tooling 3 holding a workpiece 8 to be hinged is slidably input into the hinge station 22 along the sliding channel 21 by an external conveyor belt or other conveying mechanism. Then, the positioning module 4 fixes the workpiece 8 to be hinged in the hinge station 22 to prevent movement during subsequent hinge processes, which could affect hinge accuracy and quality. Finally, the hinge module 5 presses down on the workpiece 8 on the hinge station 22 to press the iron core 81 of the workpiece 8 into the yoke 83. After hinge is completed, the hinge module 5 and the positioning module 4 release the hinged workpiece 8 from the hinge station 22 together, and the external conveying mechanism inputs the next tooling 3 holding a workpiece 8 to be hinged into the hinge station 22, thereby moving the hinged workpiece 8 out of the hinge station 22. This process is repeated continuously to achieve continuous hingeding of the workpiece 8 to be hinged. As can be seen, compared with the prior art, the input and output ends of the sliding channel 21 of this utility model can be directly connected to the external conveying mechanism to receive the workpiece 8 to be hinged by the external conveying mechanism and send the hinged workpiece 8 to the external conveying mechanism. The material is directly fed by the external conveying mechanism, eliminating the need for additional robotic arm feeding, greatly simplifying the operation process, reducing equipment costs, and effectively improving production efficiency. It also reduces the uncertainty and failure risk in the production process, thereby meeting the needs of the relay manufacturing industry for efficient and stable production.

[0050] See Figure 1 As shown, the tooling 3 can be provided with a placement groove 31, which is adapted to the workpiece 8 to be hinged, and is used to place and limit the workpiece 8 to be hinged.

[0051] See Figure 2 and Figure 3 As shown, Figure 2 This is a perspective view of the workbench, tooling, and positioning module in the embodiment. Figure 3The figure shows a cross-sectional view of the workbench, tooling, and hinge module in an embodiment. In the first embodiment of the workbench 2, the workbench 2 includes a movable platform 23 and two fixed platforms 24. The movable platform 23 is vertically slidably connected to the frame 1 and has a first channel 231 for sliding connection with the tooling 3. The sliding trajectory of the movable platform 23 includes a first position and a second position arranged vertically. An elastic element (not shown in the figure) is installed between the movable platform 23 and the frame 1. The elastic element has a spring force that drives the movable platform 23 to slide towards the first position. The positioning module 4 is installed on the movable platform 23 and can move up and down synchronously with the movable platform 23 to ensure that the positioning function of the positioning module 4 is not affected by the up and down movement. The hinge station 22 is located on the first channel 231. The two fixed platforms 24 are fixed to the frame 1 by welding or screwing, and the two fixed platforms 24 are located on both sides of the movable platform 23. The fixed platforms 24 have a second channel 241 for sliding connection with the tooling 3. When the movable platform 23 is in the first position, the positioning module 4 opens both ends of the first channel 231, and the two ends of the first channel 231 are respectively connected to and connected to the two second channels 241 to form a sliding channel 21; when the movable platform 23 is in the second position, the positioning module 4 blocks both ends of the first channel 231, and the first channel 231 and the second channel 241 are completely staggered. Thus, during hinge operation in this embodiment, the positioning module 4 blocks both ends of the first channel 231, fixing the workpiece 8 to be hinged at the hinge position 22. Simultaneously, the hinge module 5 presses down on the workpiece 8 to be hinged at the hinge position 22, overcoming the elastic force of the elastic element, and driving the movable table 23 to descend relative to the fixed table 24 to the second position, pressing the iron core 81 of the workpiece 8 to be hinged into the yoke 83, preventing the external conveying mechanism from inputting the next workpiece 8 to be hinged into the first channel 231 before the previous workpiece 8 has finished hinged. After the hinge is completed, the hinge module 5 and the positioning module 4 release the hinged workpiece 8 on the hinge position 22 together, opening both ends of the first channel 231. The movable table 23 returns to its original position under the elastic force of the elastic element, thereby placing the first channel 231 and the second channel 241 on the same straight line, connecting to form a sliding channel 21, so that the external conveying mechanism can input the next workpiece 8 to be hinged into the first channel 231 and drive the hinged workpiece 8 out of the first channel 231. As can be seen, the workbench 2 provided in this embodiment can be easily connected to the external conveying mechanism through the fixed platform 24, and the connection position between the workbench 2 and the external conveying mechanism is fixed, ensuring that the workbench 2 can receive the workpiece 8 to be hinged and the tooling 3 input by the external conveying mechanism, and also ensuring that the workbench 2 can output the hinged workpiece 8 and the tooling 3 together to the external conveying mechanism; and through the cooperation of the movable platform 23 and the elastic element, it can not only prevent the hinge module 5 from being over-pressurized, thus protecting the workbench 2 and the workpiece 8 from damage, but also play a material distribution role together with the positioning module 4, preventing the next workpiece 8 from being input into the movable platform 23 before the hinge of the previous workpiece 8 is completed.

[0052] The aforementioned elastic components can be made of springs or other elastic parts.

[0053] In a second embodiment of the workbench 2, the workbench 2 includes a movable platform 23. The movable platform 23 is vertically slidably connected to the frame 1. The movable platform 23 has a first channel 231, which is configured as a sliding channel 21. The sliding trajectory of the movable platform 23 includes a first position and a second position arranged vertically. An elastic element is installed between the movable platform 23 and the frame 1, and the elastic element has a spring force that drives the movable platform 23 to slide towards the first position. A positioning module 4 is installed on the movable platform 23. When the movable platform 23 is in the first position, the positioning module 4 opens both ends of the first channel 231, and the sliding channel 21 is connected and communicated with the external conveying mechanism; when the movable platform 23 is in the second position, the positioning module 4 blocks both ends of the first channel 231, and the sliding channel 21 is staggered from the external conveying mechanism. Thus, the hinge process in this embodiment is the same as in the previous embodiment, and the effect of the movable platform 23 is also the same. The only difference between the two embodiments is that the workbench 2 provided in this embodiment does not include a fixed platform 24, which can further reduce equipment costs.

[0054] See Figure 1 and Figure 2 As shown, in one embodiment of the positioning module 4, the positioning module 4 includes a positioning block driving assembly 42 and two positioning blocks 41. The two positioning blocks 41 are located on opposite sides of the movable platform 23, and each of the two positioning blocks 41 has a limiting groove 411 on its facing side. A limiting space 412 is formed between the two limiting grooves 411. The positioning block driving assembly 42 is mounted on the movable platform 23 by screwing or welding, and is drively connected to the two positioning blocks 41. The positioning block driving assembly 42 is used to drive the two positioning blocks 41 to move closer to or further away from each other along a first direction. The first direction is perpendicular to both the extension direction of the sliding channel 21 and the vertical direction. Thus, the positioning block drive assembly 42 drives the two positioning blocks 41 to move closer to each other along the first direction, forming a limiting space 412 adapted to the workpiece 8 to be hinged. This not only restricts the horizontal position of the workpiece 8 and positions the workpiece 8 to be hinged, but also effectively prevents the workpiece 8 from moving during the hinge process and affecting the hinge. The positioning blocks 41 can also block both ends of the first channel 231, preventing the external conveying mechanism from inputting the next workpiece 8 to be hinged into the first channel 231 before the previous workpiece 8 has finished hinged.

[0055] The aforementioned positioning block drive assembly 42 can use two telescopic cylinders to control the two positioning blocks 41 individually, or it can use a motor-double-acting screw nut or other drive mechanism to control the two positioning blocks 41 simultaneously.

[0056] See Figure 1 and Figure 2As shown, based on the above embodiment, the novel iron core hinge mechanism further includes a positioning detection element 6. The positioning detection element 6 is installed on the frame 1 or the fixed platform 24 and is used to detect whether the movable platform 23 is in the first position. In this way, the detection result of the positioning detection element 6 can be used to conveniently control the cycle time of the external conveying mechanism conveying the tooling 3.

[0057] The aforementioned positioning detection element 6 can use existing positioning switches or distance sensors.

[0058] See Figure 1 and Figure 3 As shown, in one embodiment of the hinge module 5, the hinge module 5 includes a pressure column 51 and a pressure column drive member 52. The pressure column 51 is located above the hinge station 22 and is positioned opposite to the iron core 81 on the hinge station 22. The pressure column drive member 52 is mounted on the frame 1 by means of screwing or welding and is connected to the pressure column 51 in a transmission manner. The pressure column drive member 52 is used to drive the pressure column 51 to move toward or away from the hinge station 22 to press the iron core 81 into the insertion port 831 of the yoke 83. In this way, the pressure column drive member 52 drives the pressure column 51 to descend toward the hinge station 22, thereby pressing down the iron core 81 of the workpiece 8 to be hinged on the hinge station 22, pressing the iron core 81 of the workpiece 8 to be hinged into the insertion port 831 of the yoke 83, thereby realizing the function of automatic hinge and improving production efficiency.

[0059] The aforementioned pressure column drive component 52 can use existing linear drive mechanisms such as telescopic cylinders, motor-screw-nut linear modules, etc., and its output end is connected to the pressure column 51 by means of screwing or welding.

[0060] See Figure 1 and Figure 3 As shown, based on the above embodiment, the hinge module 5 further includes a pressure block 53. The pressure block 53 is positioned opposite to the tooling 3 and is connected to the pressure column drive member 52. The pressure column drive member 52 is used to drive the pressure column 51 and the pressure block 53 to move together toward or away from the hinge position 22. Thus, during hinge, the pressure column drive member 52 drives the pressure column 51 to press down on the iron core 81. After the iron core 81 is assembled into place, the pressure block 53 abuts against the tooling 3, preventing the iron core 81 from continuing to descend relative to the tooling 3, so as to avoid excessive pressure on the iron core 81 and damage to its connection structure with the yoke 83.

[0061] See Figure 3As shown, based on the above embodiment, the hinge module 5 also includes a support column 54. The support column 54 is fixed to the frame 1 by means of screwing or welding, and is positioned opposite to the pressure column 51. Both the worktable 2 and the tooling 3 have clearance channels 7 for the support column 54 to pass through. Thus, during the hinge process when the pressure column drive member 52 drives the pressure column 51 to descend towards the hinge position 22, the support column 54 can support the workpiece 8 to be hinged, especially the iron core 81 of the workpiece 8, thereby improving the hinge effect of the hinge module 5.
