Description

Technical Field

[0001] This utility model relates to the field of relay manufacturing technology, specifically to a novel yoke spring riveting 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. In the relay manufacturing process, the riveting process of the yoke and moving spring is one of the crucial steps. This riveting process is as follows: First, the moving spring assembly and the yoke assembly need to be assembled separately. Then, the moving spring assembly and the contact terminal are placed sequentially on top of the yoke assembly, aligning the protrusions on the yoke assembly with the through holes of the moving spring assembly and the contact terminal. Finally, a certain downward pressure is applied by the riveting mechanism, allowing the protrusions to smoothly pass through the through holes of the moving spring assembly and the contact terminal, thereby firmly pressing the yoke assembly, moving spring assembly, and contact terminal together to form a relay component that meets the design requirements.

[0003] However, existing yoke-spring riveting mechanisms heavily rely on manual operation. Before each riveting operation, the workpiece to be riveted must be manually moved to the working position of the mechanism. After the riveting operation is completed by the yoke-spring riveting mechanism, the riveted workpiece must again be manually moved out of the working position to make room for the next riveting operation. This frequent manual handling severely affects the continuity of the entire production process, making it difficult to effectively improve production efficiency. Moreover, due to the randomness and uncertainty of manual operation, it is difficult to guarantee the assembly accuracy and quality of the workpiece.

[0004] Given the many drawbacks of existing yoke spring riveting mechanisms, it is particularly necessary to develop a new type of yoke spring riveting mechanism that can automatically input the workpiece to be riveted and automatically output the riveted workpiece. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel yoke moving spring riveting mechanism, comprising:

[0009] frame;

[0010] The conveyor table is located on the frame and is equipped with a conveyor channel for docking and connecting with external conveying mechanisms. The conveyor channel is equipped with a riveting station.

[0011] The tooling is slidably connected to the conveyor channel of the conveyor table. The tooling is used to accommodate the yoke assembly and the moving spring assembly and contact terminals set on the yoke assembly, and to limit the yoke assembly.

[0012] The clamping module is located on the frame and is positioned opposite to the riveting station. The clamping module is used to clamp or release the yoke assembly on the riveting station.

[0013] The riveting module is mounted on the frame and located above the riveting station. The riveting module is used to press down the moving spring assembly and contact terminal on the riveting station to rivet the yoke assembly, moving spring assembly and contact terminal into one unit.

[0014] Further, the aforementioned clamping module includes:

[0015] Two clamping arms are arranged symmetrically to each other and along the extension direction of the conveying channel;

[0016] The clamping arm drive assembly is mounted on the frame and connected to the clamping arm drive. The clamping arm drive assembly is used to drive the two clamping arms to move toward the riveting station and approach each other, or to move away from the riveting station and move away from each other.

[0017] Further configuration: the aforementioned clamping arm drive assembly includes a first slider, a first drive member, a second slider, and a second drive member. Two first sliders and two second sliders are symmetrically arranged. The second slider is provided with a slide groove, which includes a section of inclined track. The tracks of the two second sliders extend in a direction close to the riveting station and away from each other. The clamping arm is slidably disposed on the first slider along a first direction and slidably connected to the slide groove. The first drive member is disposed on the frame. The output end of the first drive member is connected to the second drive member and the two first sliders. The output end of the second drive member is connected to the two second sliders.

[0018] The first driving member is used to drive the second driving member and the two first sliders to move toward or away from the riveting station along the second direction, so as to drive the two clamping arms to move toward or away from the riveting station. The second driving member is used to drive the two second sliders to move toward or away from the riveting station along the second direction, so as to drive the two clamping arms to move closer to or further away from each other. The first direction is the extension direction of the conveying channel, and the second direction is set perpendicular to the first direction and the vertical direction.

[0019] Furthermore, the bottom of the aforementioned clamping arm is provided with an arc-shaped clamping surface, which is used to contact the coil surface of the yoke assembly.

[0020] Further configuration, the aforementioned conveyor platform includes:

[0021] The movable table can slide vertically on the frame and has a first channel. 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 riveting station is located on the first channel.

[0022] Two fixed platforms are mounted on the frame and located on both sides of the movable platform. A second passage is provided on the fixed platforms.

[0023] When the platform is in the first position, the two ends of the first channel are connected to the two second channels to form a conveying channel; when the platform is in the second position, the first channel and the second channel are completely staggered.

[0024] Further, the aforementioned conveyor table includes a limiting block, which is located on one side of the conveying channel, and the extending direction of the limiting block is parallel to the extending direction of the conveying channel.

[0025] The new type of yoke spring riveting mechanism also includes a positioning module, which includes a positioning block and a positioning block drive. The positioning block and the limiting block are positioned opposite each other on both sides of the riveting station. The positioning block drive is located on the movable table and is connected to the positioning block for transmission. The positioning block drive is used to drive the positioning block to move towards or away from the limiting block so as to fix the workpiece on the riveting station.

[0026] Further, the aforementioned riveting module includes a pressure column and a pressure column drive. The pressure column is located above the riveting station and is positioned opposite to the protrusion of the yoke assembly. The pressure column drive is located 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 riveting station so that the protrusion passes through the through hole of the moving spring assembly and the contact terminal.

[0027] Furthermore, the aforementioned riveting module also includes two pressure arms, which are respectively located on both sides of the pressure column and are positioned opposite to the two sides of the tooling. The pressure column drive is also connected to the pressure arm drive, which is used to drive the pressure column and the two pressure arms to move together toward or away from the riveting station.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the novel yoke spring riveting mechanism provided by this utility model has the following beneficial effects:

[0030] When using the novel yoke-spring riveting mechanism provided by this utility model, firstly, a tooling containing a workpiece to be riveted is slidably input into the riveting station along the conveyor channel via an external conveyor belt or other conveying mechanism (the workpiece to be riveted includes a yoke assembly and a spring assembly and contact terminals placed sequentially on the yoke assembly, wherein the protrusion of the yoke assembly is aligned with the through holes of the spring assembly and contact terminals); then, the clamping module fixes the workpiece to be riveted in the riveting station to prevent the workpiece from moving during the subsequent riveting process, thus affecting the riveting process. The riveting module presses down on the workpiece to be riveted at the riveting station, allowing the protrusion to pass through the through holes of the moving spring assembly and the contact terminal, thereby riveting the yoke assembly, moving spring assembly, and contact terminal into one unit. After riveting is completed, the riveting module and the positioning module release the riveted workpiece from the riveting station together. The external conveying mechanism inputs the next tooling containing the workpiece to be riveted into the riveting station, thereby moving the riveted workpiece out of the riveting station. This process is repeated continuously to achieve continuous riveting of the workpieces to be riveted. It can be seen that, compared with the prior art, this utility model, through the connection of the conveying channel with the external conveying mechanism, can utilize the external conveying mechanism to feed materials, thereby realizing the automatic input of the workpiece to be riveted and the automatic output of the riveted workpiece at the riveting station, replacing manual handling, effectively improving production efficiency, and ensuring the assembly accuracy and quality of the workpieces.

[0044] 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.

[0045] This utility model provides a novel riveting mechanism with a yoke and moving spring, which solves the problem of how to automatically input the workpiece 7 to be riveted and automatically output the riveted workpiece 7.

[0046] See Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the novel yoke spring riveting mechanism in the embodiment. Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that the new type of yoke spring riveting mechanism includes a frame 1, a conveyor table 2, a tooling 3, a clamping module 4, and a riveting module 5.

[0047] The conveyor table 2 is mounted on the frame 1, and the conveyor table 2 has a conveying channel 21 for docking and connecting with an external conveying mechanism. The conveying channel 21 is provided with a riveting station 22.

[0048] The tooling 3 is slidably connected to the conveying channel 21 of the conveyor table 2. The tooling 3 is used to accommodate the yoke assembly 71 and the moving spring assembly 72 and the contact terminal 73 placed on the yoke assembly 71 in sequence, and is also used to limit the yoke assembly 71. The yoke assembly 71 and the moving spring assembly 72 and the contact terminal 73 placed on the yoke assembly 71 in sequence are combined to form the workpiece 7 to be riveted.

[0049] The clamping module 4 is mounted on the frame 1 and positioned opposite to the riveting station 22. The clamping module 4 is used to clamp or release the yoke assembly 71 on the riveting station 22.

[0050] The riveting module 5 is mounted on the frame 1 and located above the riveting station 22. The riveting module 5 is used to press down the moving spring assembly 72 and the contact terminal 73 on the riveting station 22 to rivet the yoke assembly 71, the moving spring assembly 72 and the contact terminal 73 into one piece.

[0051] Combination Figure 3 As shown, Figure 3 The diagram shows a perspective view of the conveyor platform, tooling, and clamping module in the embodiment. When the novel yoke-spring riveting mechanism of the above technical solution is used, firstly, a tooling 3 holding a workpiece 7 to be riveted is slidably input into the riveting station 22 along the conveying channel 21 via an external conveyor belt or other conveying mechanism. Then, the clamping module 4 fixes the workpiece 7 to be riveted in the riveting station 22 to prevent the workpiece 7 from moving during the subsequent riveting process, thus affecting the riveting accuracy and quality. Finally, the riveting module 5 presses down on the workpiece 7 to be riveted in the riveting station 22 so that the protrusion 711 passes through the through hole 731 of the spring assembly 72 and the contact terminal 73, thereby riveting the yoke assembly 71, the spring assembly 72, and the contact terminal 73 into one unit. After riveting is completed, the riveting module 5 and the positioning module 6 release the riveted workpiece 7 from the riveting station 22. The external conveying mechanism then inputs the tooling 3, which holds the next workpiece 7 to be riveted, into the riveting station 22, thereby moving the riveted workpiece 7 out of the riveting station 22. This process is repeated continuously to achieve continuous riveting of the workpiece 7. It can be seen that, compared with the prior art, this invention, through the connection of the conveying channel 21 with the external conveying mechanism, can utilize the external conveying mechanism for feeding, thereby automatically inputting the workpiece 7 to be riveted and automatically outputting the riveted workpiece 7 into the riveting station 22, replacing manual handling, effectively improving production efficiency, and ensuring the assembly accuracy and quality of the workpiece 7.

[0052] See Figure 2 and Figure 3 As shown, a placement groove 31 can be provided on the tooling 3. The placement groove 31 is adapted to the yoke assembly 71 and is used to place and limit the yoke assembly 71.

[0053] See Figure 3As shown, in one embodiment of the clamping module 4, the clamping module 4 includes a clamping arm drive assembly 41 and two clamping arms 42. The two clamping arms 42 are symmetrically arranged along the extension direction of the conveying channel 21. The clamping arm drive assembly 41 is mounted on the frame 1 and is throttle-connected to the clamping arms 42. The clamping arm drive assembly 41 is used to drive the two clamping arms 42 to move toward the riveting station 22 and move closer to each other, or to move away from the riveting station 22 and move away from each other. Thus, when the two clamping arms 42 move to the riveting station 22, they can not only prevent the workpiece 7 to be riveted from moving out of the riveting station 22, but also prevent the external conveying mechanism from inputting the next workpiece 7 to be riveted into the riveting station 22. Conversely, when the clamping arms 42 move away from the riveting station 22, they can provide clearance, making it convenient for the riveted workpiece 7 to leave the riveting station 22. When the two clamping arms 42 move to the riveting station 22 and approach each other, they can clamp and fix the workpiece 7 to be riveted on the riveting station 22. In this process, if the workpiece 7 to be riveted is not accurately conveyed to the riveting station 22, the clamping arms 42 can also move the workpiece 7 between them toward the riveting station 22 while approaching each other, ensuring that the workpiece 7 to be riveted is clamped and fixed on the riveting station 22.

[0054] See Figure 3 , Figure 4 and Figure 5 As shown, Figure 4 for Figure 3 Enlarged diagram at point B in the middle. Figure 5This is a perspective view of the clamping module in one embodiment. In one implementation of the clamping arm driving assembly 41, the clamping arm driving assembly 41 includes a first slider 411, a first driving member 412, a second slider 413, and a second driving member 414. Two first sliders 411 and two second sliders 413 are symmetrically arranged. Each second slider 413 has a groove 4131, which includes an inclined track 41311. The tracks 41311 of the two second sliders 413 extend in a direction close to the riveting station 22 and away from each other. The clamping arm 42 is slidably connected to the first slider 411 along a first direction and slidably connected to the groove 4131. The first driving member 412 is mounted on the frame 1 by screwing or welding, and its output end is connected to the second driving member 414 and the two first sliders 411 by screwing or welding. The output end of the second driving member 414 is connected to the two second sliders 413 by screwing or welding. The first driving member 412 drives the second driving member 414 and the two first sliders 411 to move towards or away from the riveting station 22 along the second direction, thereby causing the two clamping arms 42 to move towards or away from the riveting station 22. The second driving member 414 drives the two second sliders 413 to move towards or away from the riveting station 22 along the second direction, thereby causing the two clamping arms 42 to move closer to or further away from each other. The first direction is the extension direction of the conveying channel 21, and the second direction is perpendicular to the first direction and the vertical direction. Thus, the clamping arm drive assembly 41 drives the two first sliders 411 to move toward or away from the riveting station 22 via the first drive member 412, thereby causing the two clamping arms 42 to move toward or away from the riveting station 22. When the clamping arm drive assembly 41 drives the two second sliders 413 to move along the second direction via the second drive member 414, it can drive the clamping arms 42 to move along the corresponding slide groove 4131. However, since the first sliders 411 restrict the clamping arms 42 to slide only along the first direction, the two second sliders 413 can drive the two clamping arms 42 to move closer to or further away from each other via the corresponding slide groove 4131 track 41311.

[0055] Both the first driving component 412 and the second driving component 414 mentioned above can use existing linear drive mechanisms such as telescopic cylinders and telescopic poles.

[0056] See Figure 4 As shown, in one embodiment of the clamping arm 42, the bottom of the clamping arm 42 has an arc-shaped clamping surface 421, which is used to contact the coil 712 surface of the yoke assembly 71. Thus, the clamping surface 421 increases the contact area between the clamping arm 42 and the workpiece 7 to be riveted, thereby improving the clamping and positioning effect of the clamping module 4 and effectively preventing damage to the workpiece 7 by the clamping module 4, ensuring the quality of the workpiece 7.

[0057] See Figure 4As shown, the clamping arm 42 includes a sliding protrusion 422 for sliding connection with the groove 4131.

[0058] See Figure 1 and Figure 3 As shown, in one embodiment of the conveyor table 2, the conveyor table 2 includes a movable table 23 and two fixed tables 24. The movable table 23 is vertically slidably connected to the frame 1 and has a first channel 231. The sliding trajectory of the movable table 23 includes a first position and a second position arranged vertically. An elastic element (not shown in the figure) is installed between the movable table 23 and the frame 1. The elastic element has a spring force that drives the movable table 23 to slide towards the first position. A riveting station 22 is provided on the first channel 231. The two fixed tables 24 are fixed to the frame 1 by welding or screwing, and the two fixed tables 24 are respectively located on both sides of the movable table 23. The fixed tables 24 have a second channel 241. Wherein, when the movable table 23 is in the first position, the two ends of the first channel 231 are respectively connected to the two second channels 241 to form a conveying channel 21; when the movable table 23 is in the second position, the first channel 231 and the second channel 241 are completely offset. Thus, the conveyor 2 can be easily connected to the external conveying mechanism through the fixed platform 24, and the connection position between the conveyor 2 and the external conveying mechanism is fixed to ensure that the conveyor 2 can automatically feed materials using the external conveying mechanism; and through the cooperation of the movable platform 23 and the elastic element, it can not only prevent the riveting module 5 from being over-pressurized, thus protecting the conveyor 2 and the workpiece 7 from damage, but also play a role in material distribution, preventing the next workpiece 7 from being input into the riveting station 22 of the movable platform 23 before the riveting of the previous workpiece 7 is completed.

[0059] The aforementioned elastic components can be made of springs or other elastic parts.

[0060] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, based on the above embodiment, the conveyor table 2 includes a limiting block 25. The limiting block 25 is located on one side of the conveying channel 21, and the extending direction of the limiting block 25 is parallel to the extending direction of the conveying channel 21. The novel yoke spring riveting mechanism also includes a positioning module 6, which includes a positioning block 61 and a positioning block drive 62. The positioning block 61 and the limiting block 25 are positioned opposite each other on both sides of the riveting station 22. The positioning block drive 62 is mounted on the movable table 23 by means of screwing or welding, and is connected to the positioning block 61 in a transmission manner. The positioning block drive 62 is used to drive the positioning block 61 to move towards or away from the limiting block 25, so as to fix the workpiece 7 on the riveting station 22. Thus, since the movable table 23 can be raised and lowered, while the clamping module 4 is fixed on the frame 1, the positioning module 6, which can be raised and lowered with the movable table 23, needs to work with the clamping module 4 to further fix the workpiece 7 to be riveted on the riveting station 22, ensuring that the workpiece 7 to be riveted will not be displaced relative to the movable table 23, so as not to affect the riveting; and the positioning module 6 drives the positioning block 61 to move toward the limiting block 25 through the positioning block drive 62, and can fix the workpiece 7 to be riveted on the riveting station 22 by cooperating with the limiting block 25.

[0061] The aforementioned positioning block drive component 62 can use existing linear drive mechanisms such as telescopic cylinders and telescopic poles, and its output end is connected to the positioning block 61 by means of screwing or welding.

[0062] See Figure 1 and Figure 2 As shown, in one embodiment of the riveting module 5, the riveting module 5 includes a pressure post 51 and a pressure post drive member 52. The pressure post 51 is located above the riveting station 22 and is positioned opposite to the protrusion 711 of the yoke assembly 71. The pressure post drive member 52 is mounted on the frame 1 by means of screwing or welding and is drively connected to the pressure post 51. The pressure post drive member 52 is used to drive the pressure post 51 to move toward or away from the riveting station 22, so that the protrusion 711 passes through the through hole 731 of the moving spring assembly 72 and the contact terminal 73. In this way, when the pressure post drive member 52 drives the pressure post 51 to descend toward the riveting station 22, it can simultaneously press down on the through hole 731 of the moving spring assembly 72 and the contact terminal 73, so that the protrusion 711 can smoothly pass through the through hole 731 of the moving spring assembly 72 and the contact terminal 73, thereby realizing the function of automatic riveting and improving production efficiency.

[0063] 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.

[0064] See Figure 1 and Figure 2As shown, based on the above embodiment, the riveting module 5 further includes two pressure arms 53. The two pressure arms 53 are located on both sides of the pressure column 51 and are positioned opposite to the two sides of the tooling 3. The pressure column drive member 52 is also connected to the pressure arms 53 in a transmission manner. The pressure column drive member 52 is used to drive the pressure column 51 and the two pressure arms 53 to move together toward or away from the riveting station 22. Thus, during riveting, the pressure column drive member 52 drives the pressure column 51 to press down the moving spring assembly 72 and the contact terminal 73. After the moving spring assembly 72 and the contact terminal 73 are assembled in place, the pressure arms 53 abut against the two sides of the tooling 3, preventing the moving spring assembly 72 and the contact terminal 73 from continuing to descend relative to the tooling 3, so as to avoid the pressure column 51 pressing down excessively and damaging the workpiece 7.

[0065] See Figure 2 As shown, the two pressure arms 53 can be arranged along the extension direction of the conveying channel 21, or they can be arranged in a direction perpendicular to the extension direction of the conveying channel 21. If the latter, the bottom of the pressure arm 53 needs to have a clearance recess 531 for the positioning block 61 or the limiting block 25 to be inserted. The clearance recess 531 is used to provide clearance so as to prevent the pressure arm 53 from interfering with the positioning block 61 or the limiting block 25.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
