Description

Technical Field

[0001] This invention relates to the assembly of a push rod in a relay, and more particularly to the assembly of a moving spring in the push rod. Background Technology

[0002] Referring to Chinese patent CN202220800609 and Figure 1a and Figure 1b Relays typically have a push rod assembly, which includes a push rod 201, a movable spring 204, a magnetic conductor 202, a frame 203, and a spring (not shown in the figure). The push rod 201 protrudes from the top of the frame 203. The magnetic conductor 202 is installed inside the frame 203 and is near the bottom of the frame 203. The movable spring 204 enters the frame 203 from the side entrance and abuts against the magnetic conductor 202 on the top and bottom of the frame 203 in the push rod assembly 200. Therefore, in relay production, the movable spring 204 often needs to be installed manually inside the frame 203, which is inefficient and prone to errors.

[0003] To address this, Chinese patent CN201710953612.6 discloses a pre-compression spring assembly device for a relay push rod assembly. First, the push rod assembly is installed via a mounting base. Then, a protrusion with a platform extends into the dustproof frame (frame) of the push rod assembly. The pre-compression spring is then placed on the platform, compressed to a preset height by a pressing plate, and finally fed into the dustproof frame via a small pusher on the pre-compression plate, thus achieving automatic assembly of the pre-compression spring. However, this assembly device has the following problems: ① The pre-compression spring must be compressed to a preset size before being moved to the dustproof frame, which takes a considerable amount of time. Furthermore, if the angle of the pre-compression spring is slightly off when the pre-compression plate compresses it, it is difficult to avoid a slight lateral tilt, making the assembly device prone to errors. Also, since the compression of the pre-compression plate is generally driven by a pneumatic motor and takes a very short time, the pre-compression spring may accidentally pop out of the platform during compression. ② The pre-pressure plate can only push the pre-pressure spring into the dustproof frame through the small pusher on it. During this process, the pre-pressure plate moves with the pre-pressure spring, while the platform remains stationary. That is, the pre-pressure plate and the platform at the upper and lower ends of the pre-pressure spring move relative to each other. Due to the friction between the pre-pressure spring and the platform, the pre-pressure spring can easily tilt during movement, causing assembly failure.

[0004] Therefore, there is an urgent need for a relay moving spring assembly device that can solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a relay moving spring assembly device that can quickly and stably compress and transport the moving spring into the frame of the push rod assembly to complete the assembly of the moving spring. The process is simple and controllable.

[0006] To achieve the above objectives, the present invention discloses a relay moving spring assembly device for abutting the two ends of a moving spring between the top and bottom of a frame in a push rod assembly. The device includes a guide member, a feeding drive mechanism, and a spring pushing mechanism. The guide member has a spring conveying channel, which is arranged along a first direction and includes an inlet and an outlet. Near the outlet, the spring conveying channel has a guide head that can extend into the frame along the first direction. A guide region with a gradually decreasing height towards the outlet is formed in a portion of the length of the spring conveying channel near the outlet. The feeding drive mechanism drives the guide member to move along the first direction between a first position and a second position. In the first position, the inlet is located at an inlet position, and in the second position, the outlet is located at an assembly position. The spring pushing mechanism pushes the moving spring along the spring conveying channel from the inlet to the outlet.

[0007] Compared with existing technologies, this invention, on the one hand, delivers the moving spring through a spring conveying channel while simultaneously performing progressive compression, resulting in high efficiency and effective control over the compression speed, ensuring smooth compression. On the other hand, the moving spring is pushed from the rear by a first pusher rod, sliding within the spring conveying channel. The conveying channel walls at both ends of the moving spring slide synchronously relative to it, effectively preventing tilting during compression and ensuring precise entry of the moving spring into the frame of the pusher rod. Furthermore, during the assembly of the moving spring, this invention only requires controlling the guide member to advance so that the guide head extends into the frame, after which the spring pusher mechanism pushes the moving spring along the spring conveying channel to its outlet. This reduces the number of steps and makes the process simple and controllable.

[0008] Preferably, the spring pushing mechanism includes a first driving part and a first pushing rod. The first driving part can drive the first pushing rod to slide in the spring conveying channel and push the moving spring from the feed port to the discharge port.

[0009] Preferably, the guide includes a conveying block and a guide block, each having a spring conveying channel. The spring conveying channels in the conveying block are at the same height, and at least a portion of the spring conveying channels in the guide block gradually decrease in height towards the discharge port to form the guide area. The guide block is fixedly connected to the conveying block, and the spring conveying channels of the conveying block and the guide block are connected.

[0010] Preferably, the spring conveying channel has a notch at the top and bottom of the discharge port that is slightly smaller than the moving spring. This notch can just catch the moving spring when it moves to the discharge port. When the guide retracts and resets, the guide can quickly disengage from the moving spring, preventing the position where the moving spring contacts the guide from tilting or even disengaging from the assembly position when the guide retracts.

[0011] Preferably, the spring conveying channel has a uniform height within a preset length range at the discharge port or gradually expands towards the discharge port to form a discharge area, and the guide area is adjacent to the discharge area.

[0012] Preferably, the spring conveying channel has an upper limit wall, a lower limit wall, a left limit wall, and a right limit wall at each position from the inlet to the outlet. A compression portion is formed between the upper and lower limit walls to limit and compress the height of the movable spring. A sliding portion is formed between the left and right limit walls to slide in cooperation with the first push rod. This effectively prevents the movable spring from accidentally popping out of the spring conveying channel and precisely guides the end of the first push rod, ensuring the conveying direction and stability of the movable spring.

[0013] Specifically, the lateral width of the end section of the first push rod matches the lateral width of the spring conveying channel, and the first push rod is slidably connected to the spring conveying channel. The height of the end section of the first push rod is greater than or equal to half the height at the inlet of the spring conveying channel, and it abuts against the middle position in the height direction of the moving spring when conveying the moving spring. This scheme further prevents the moving spring from tilting during conveying.

[0014] Preferably, the relay moving spring assembly device further includes a control mechanism. When the guide is in the first position and the moving spring reaches the feeding position, the control mechanism controls the feeding drive mechanism to move the guide forward to the second position, so that the guide head extends into the frame from the side opening of the frame. When the guide moves to the second position, the control mechanism controls the spring pushing mechanism to move the moving spring from the feeding port to the discharging port, so that the moving spring is gradually compressed and moves into the frame. When the moving spring is pushed to the discharging port, the control mechanism controls the feeding drive mechanism to move the guide back to the first position, so that the moving spring disengages from the guide and abuts against the first side of the push rod and the magnetic conductor, thereby completing the installation of the moving spring.

[0015] Specifically, the control mechanism also controls the spring pusher mechanism to reset when the guide member retracts to the first position.

[0016] Specifically, the relay moving spring assembly device further includes a first detection mechanism and a second detection mechanism. A first detection window is provided at the top of the guide head, approximately a preset distance from the discharge port. The first detection mechanism detects the moving spring at the first detection window when the guide moves to the second position to generate a first detection signal. The control mechanism determines that the moving spring has been pushed to the discharge port when the spring pushing mechanism is in position and receives the first detection signal. The first detection mechanism, through the first detection window, can determine whether the moving spring is about to reach the frame before the push rod moves to the forward position, thus timely and accurately verifying whether the moving spring has reached its normal position, and promptly stopping the next assembly step if there is a material shortage or a problem with the moving spring.

[0017] The spring conveying channel has a second detection window at the top of the feed inlet. The second detection mechanism detects the moving spring at the second detection window when the guide moves to the first position to generate a second detection signal. The control mechanism determines that the guide is in the first position and the moving spring has reached the feed position based on the second detection signal.

[0018] Preferably, the relay moving spring assembly device further includes a spring feeding mechanism, which, when the spring conveying channel is in the first position, conveys the moving spring at the feeding position to the inlet at the feeding position; the spring feeding mechanism includes a feeding channel arranged along a second direction, a second push rod, and a second driving part, the feeding channel connecting the feeding position and the feeding position, the second push rod being slidably installed in the feeding channel, and the second driving part driving the second push rod to slide in the feeding channel and push the moving spring along the feeding position to the feeding position, wherein the first direction and the second direction are perpendicular.

[0019] Specifically, the relay moving spring assembly device further includes a material inlet channel arranged along a first direction and allowing the moving spring to move, the material inlet channel connecting the material inlet vibratory plate of the moving spring and the material supply position.

[0020] This invention also discloses a relay push rod assembly assembly device, including a conveying mechanism, a moving spring assembly mechanism, a moving spring assembly mechanism, and a detection mechanism. The conveying mechanism is used to sequentially convey a fixing fixture loading the frame of the push rod assembly to a loading station, a moving spring assembly station, a moving spring assembly station, and a detection station. The moving spring assembly mechanism is installed at the moving spring assembly station and serves as the aforementioned relay moving spring assembly device, used to install the moving spring in the frame. The moving spring assembly mechanism is installed at the moving spring assembly station and is used to insert the moving spring into the frame. The detection mechanism detects the assembly of the push rod assembly at the detection station. Attached Figure Description

[0035] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] refer to Figure 1a and Figure 1bThis invention relates to the assembly process of a push rod assembly 200, which includes a push rod 201, a movable spring 204, a magnetic conductor 202, a frame 203, and a spring (not shown in the figure). During assembly, the push rod 201 is first fixedly assembled with the frame 203 or directly machined together. Then, the magnetic conductor 202 is installed in the frame 203, with its two convex walls protruding from opposite sides of the bottom wall of the frame 203. Next, the movable spring 204 is compressed and installed in the frame 203, so that the two ends of the movable spring abut against the magnetic conductor 202 installed on the top and bottom walls of the frame 203, respectively. Finally, the magnetic conductor 202 is pushed upward, and the spring is inserted between the magnetic conductor 202 and the bottom wall of the frame 203, thus completing the assembly of the push rod assembly 200.

[0037] refer to Figure 2a and Figure 2b The present invention discloses a relay moving spring assembly device 100 for assembling a moving spring 204 into the frame 203 of a push rod assembly 200. Specifically, the moving spring 204 is placed between the magnetic conductors 202 on the top and bottom of the frame 203 in the push rod assembly 200.

[0038] refer to Figure 2a The relay moving spring assembly device 100 includes a guide member 30, a feeding drive mechanism, and a spring pushing mechanism 10. The side opening of the frame 203 faces the feeding position 301. The spring pushing mechanism 10 pushes the moving spring 204 into the frame along the spring conveying channel 34 of the guide member 30. The spring conveying channel 34 of the guide member 30 guides the moving spring 204 into the frame 203 and compresses the moving spring. The feeding drive mechanism drives the guide member 30 to move along a first direction between a first position and a second position.

[0039] During operation, the present invention positions the movable spring 204 at the assembly position 302 using the fixing fixture 103. Specifically, when the fixing fixture 103 fixes the push rod assembly 200, the magnetic conductive element 202 is positioned downwards, the side opening of the frame 203 faces the feed position 301 along the first direction, and the frame 203 is located at the assembly position 302.

[0040] refer to Figure 6The fixing fixture 103 includes a snap-fit ​​groove 61 that cooperates with the frame 203 and allows the frame 203 to be inserted and snapped into it, and an insertion hole 62 formed at the bottom of the snap-fit ​​groove 61 and corresponding to the two bent arms 2021 of the magnetic conductor 202 for insertion of the two bent arms 2021. The first side of the snap-fit ​​groove 61 has an insertion interface 63 at the mounting position of the movable spring 205 at the bottom of the frame 203 for insertion of the movable spring 205. When the fixing fixture 103 is located at the assembly position 302, the insertion interface 63 faces the feed position 301 along the first direction. The push rod assembly 200 can be installed in the fixing fixture 103 and the two bent arms of the magnetic conductor 202 can be inserted into the insertion hole 62. In the fixing fixture 103, a positioning notch 64 is provided on the first side wall of the bottom of the locking groove 61. When the robotic arm holding the frame inserts the frame 203 into the locking groove 61 from the first side, it is guided and positioned by the positioning notch 64. The entrance of the positioning notch 64 is funnel-shaped, which guides the insertion of the frame 203. The first side of the locking groove 61 does not have a groove wall. The insertion hole 62 connects to the first edge of the bottom of the locking groove 61, so that the frame 203, along with the magnetic conductor 202, can be inserted into the locking groove 61 from the first side. (Reference) Figure 5 and Figure 6 The top of the insertion hole 62 has an upper positioning platform 621 that blocks the upward movement of the magnetic conductor 202. The upper positioning platform 621 positions the upper limit of the upward movement of the magnetic conductor 202. The height of the snap-fit ​​groove 61 is lower than the height of the frame 203.

[0041] refer to Figures 2a to 2c The spring conveying channel 34 is arranged along a first direction and includes an inlet 341 and an outlet 342. The guide member 30 has a guide head 321 near the outlet 342, which can extend into the frame 203 through a side opening. (Reference) Figure 3c and 4a The spring conveying channel 34 has a guide area L1 whose height gradually decreases towards the discharge port 342 in a certain length region near the discharge port 342.

[0042] refer to Figure 2a and Figure 4a When the guide member 30 is in the first position, the feed inlet 341 is located at the feed position 301. (Reference) Figure 4b and Figure 4c When the spring conveying channel 34 is in the second position, the guide head 321 extends into the frame 203 from the side opening of the frame 203 along the first direction, and positions the discharge port 342 at the assembly position 302.

[0043] refer to Figure 2a and Figure 2c The spring pushing mechanism 10 includes a first driving part 12 and a first pushing rod 11. The first driving part 12 can drive the first pushing rod 11 to slide in the spring conveying channel 34 and push the moving spring 204 from the feed port 341 to the discharge port 342.

[0044] refer to Figures 3a to 3c The guide member 30 includes a conveying block 31 and a guide block 32. Spring conveying channels 34 are respectively provided in the conveying block 31 and the guide block 32. The spring conveying channels 34 in the conveying block 31 have the same height. The height of at least a portion of the spring conveying channels 34 in the guide block 32 gradually decreases towards the discharge port 342 to form the guide area L1. The guide block 32 is fixedly connected to the conveying block 31, and the spring conveying channels 34 at the conveying block 31 and the spring conveying channels 34 at the guide block 32 are connected.

[0045] Specifically, the upper and lower limit walls of the spring conveying channel 34 at the discharge port 342 each have a notch 322, slightly smaller than the size of the moving spring 204. This notch 322 allows the guide member 30 to quickly disengage from the moving spring 204 when it retracts and resets, preventing the contact position between the moving spring 204 and the guide member 30 from tilting or even disengaging from the assembly position 302 when the guide member 30 retracts. In this embodiment, the moving spring 204 is a cylindrical spring, and the notch 322 is semi-circular. However, it is not limited to this. When the cross-section of the moving spring 204 is rectangular, the shape of the notch 322 can be a trapezoid that gradually narrows inward, facilitating the disengagement of the moving spring 205 from the discharge port 342.

[0046] The movable spring 204 is a columnar spring. The spring conveying channel 34 has a semi-circular notch at the top and bottom of the outlet 342, which is slightly smaller than the movable spring 204. When the movable spring 204 is located at the outlet 342, the distance between the edge of the notch 322 in the middle and bottom of the spring conveying channel and the edge of the movable spring 204 near the inlet 341 is less than or equal to the diameter of the movable spring wire and greater than or equal to the radius of the movable spring wire.

[0047] refer to Figure 3c The spring conveying channel 34 has a uniform height within a preset length range at the discharge port 342 to form a discharge area L2, and the guide area L1 is adjacent to the discharge area L2. Alternatively, the height of the spring conveying channel 34 within the preset length range at the discharge port 342 can gradually increase towards the discharge port 342, so that the discharge area L2 expands outwards, facilitating the detachment of the movable spring 204 from the spring conveying channel 34.

[0048] refer to Figure 3aThe spring conveying channel 34 is formed by an upper limit wall, a lower limit wall, a left limit wall, and a right limit wall. A compression portion is formed between the upper and lower limit walls to limit and compress the height of the movable spring 204. A sliding portion is formed between the left and right limit walls to slide in conjunction with the first push rod 11. In this design, the structure of the spring conveying channel 34 effectively prevents the movable spring 204 from accidentally popping out of the channel and precisely guides the end of the first push rod 11, ensuring the conveying direction and stability of the movable spring 204.

[0049] Specifically, the lateral width of the end section of the first push rod 11 matches the lateral width of the spring conveying channel 34, and the first push rod 11 is slidably connected to the spring conveying channel 34. The height of the end section of the first push rod 11 is greater than or equal to half the height at the inlet 341 of the spring conveying channel 34, and it abuts against the middle position of the moving spring 204 in the height direction when conveying the moving spring 204. This scheme further prevents the moving spring 204 from tilting during conveying.

[0050] The relay moving spring assembly device 100 further includes a control mechanism. When the guide member 30 is in the first position and the moving spring 204 reaches the feed position 301, the control mechanism controls the feeding drive mechanism to move the guide member 30 forward to the second position, so that the guide head 321 extends into the frame 203 from the side opening of the frame 203. When the guide member 30 moves to the second position, the control mechanism controls the first drive part 12 to move the first push rod 11 in the spring conveying channel 34 to push the moving spring 204 from the feed port 341 to the discharge port 342, so that the moving spring 204 is gradually compressed and moves into the frame 203. When the moving spring 204 is pushed to the discharge port 342, the control mechanism controls the feeding drive mechanism to move the guide member 30 back to the first position, so that the moving spring 204 disengages from the guide member 30 and abuts against the first side of the push rod and the magnetic conductor, thereby completing the installation of the moving spring 204.

[0051] Specifically, the control mechanism also controls the first drive unit 12 to move when the guide member 30 retracts to the first position, so as to drive the first push rod to retract.

[0052] refer to Figures 2a to 3aThe relay spring assembly device 100 also includes a first detection mechanism. A first detection window 401 is provided on the channel wall of the spring conveying channel 34 at a preset distance from the discharge port 342. The first detection mechanism detects that when the guide member 30 moves to the second position, the spring conveying channel 34 has a moving spring 204 at a certain distance from the discharge port 342 to generate a first detection signal. When the first push rod 11 advances to its position and receives the first detection signal, the control mechanism determines that the moving spring 204 has been pushed to the discharge port 342. The first detection mechanism, through the first detection window, can determine whether the moving spring 204 is about to reach the frame 203 before the push rod moves to its forward position, thus timely and accurately verifying whether the moving spring 204 has reached its normal position, and promptly stopping the next assembly step if there is a shortage of material or an error occurs with the moving spring 204. In this invention, the first detection window 401 is located in the guide head 321, on the upper and lower limit walls of the spring conveying channel 34.

[0053] refer to Figure 2b The relay spring assembly device 100 further includes a second detection mechanism. The spring conveying channel 34 has a second detection window 402. The second detection mechanism detects the moving spring 204 at the feed inlet 341 when the guide member 30 moves to the first position to generate a second detection signal. The control mechanism determines, based on the second detection signal, that the guide member 30 is in the first position and the moving spring 204 has reached the feed position 301. In this invention, the second detection window 402 is elongated and is set on the upper limit wall of the spring conveying channel 34.

[0054] refer to Figure 2a and Figure 2c The relay moving spring assembly device 100 also includes a spring feeding mechanism 40. When the spring conveying channel 34 is in the first position, the spring feeding mechanism 40 feeds the moving spring 204 at the feeding position 303 to the feeding port 341 at the feeding position 301. The spring feeding mechanism 40 includes a feeding channel 41 arranged along a second direction, a second push rod 42, and a second driving part 43. The feeding channel 41 connects the feeding position 303 and the feeding position 301. The second push rod 42 is slidably installed in the feeding channel 41. The second driving part 43 drives the second push rod 42 to slide in the feeding channel 41 and can push the moving spring 204 along the feeding position 303 to the feeding position 301. The first direction and the second direction are perpendicular.

[0055] refer to Figure 2a and Figure 2cThe relay moving spring assembly device 100 also includes a material inlet channel 44 arranged along a first direction and allowing the moving spring 204 to move. The material inlet channel 44 connects the material inlet vibratory plate (not shown in the figure) of the moving spring 204 and the material supply position 303.

[0056] refer to Figure 2a The relay moving spring assembly device 100 also includes a third detection mechanism. A third detection window 403 is provided on the feeding channel 41, and the third detection window 403 is located on and along the feeding channel 41. The third detection mechanism detects the incoming moving spring 204 at the feeding position 303 through the third detection window 403. In this embodiment, the third detection window 403 is located on the upper limit wall of the feeding channel 41.

[0057] The length of the guide head 321 is greater than or equal to the corresponding length of the frame 203, so that the guide head 321 can extend into the other side of the frame.

[0058] refer to Figure 2a The relay spring assembly device 100 also includes a stop block 105 disposed along the side of the frame 203 away from the guide head 321 and positioned opposite to the guide head 321. When the feeding drive mechanism moves the guide head 321 to the second position, the guide head 321 abuts against the stop block 105. The fixing fixture 103 also has a notch on the side away from the guide head 321 for the stop block 105 to be inserted.

[0059] refer to Figures 2a to 7b The working process and working principle of the relay moving spring assembly device 100 of the present invention are described below:

[0060] (1) The incoming vibratory feeder delivers a movable spring 204 to the feeding position 304 of the incoming material channel 44. As the incoming vibratory feeder moves and the material is continuously fed, the movable spring 204 moves forward along the incoming material channel 44 until it reaches the feeding position 303. The third detection mechanism detects the material arrival of the movable spring 204 at the feeding position 303 through the third detection window 403 to generate a first material arrival signal. The control mechanism controls the second drive unit 43 to move according to the first material arrival signal, so that the second drive unit 43 drives the second push rod 42 to slide in the feeding channel 41 and can push the movable spring 204 along the feeding position 303 to the feeding position 301 (e.g., Figure 4a As shown in the figure, at this time, the feed port 341 is located at the feed position 301, so that the moving spring 204 directly enters the feed port 341 of the spring conveying channel 34.

[0061] (2) The second detection mechanism detects the incoming material at the feed position 301 via the second detection window 402, generating a second incoming material signal. The control mechanism controls the feeding drive mechanism to operate based on the second incoming material signal, so that the feeding drive mechanism drives the guide 30 to move from the first position along the first direction to the second position (e.g., ...). Figure 4b As shown), the feeding drive mechanism generates a feeding front position signal, at which time the feed port 341 moves forward and leaves the feed position 301, and the discharge port 342 moves forward to the assembly position 302.

[0062] (3) The control mechanism controls the first drive unit 12 to operate according to the pre-feeding position signal, so that the first drive unit 12 drives the first push rod 11 to slide in the spring conveying channel 34 and pushes the moving spring 204 from the feed port 341 to the discharge port 342. The moving spring 204 is pushed to the assembly position 302, and the spring push mechanism 10 generates a push pre-feeding position signal (such as...). Figure 4c (As shown). Specifically, when the moving spring 204 is about to reach the assembly position 302, the first detection mechanism detects the moving spring 204 through the first detection window 401 and generates a third material arrival signal.

[0063] (4) After receiving the pre-push signal and the third incoming signal, the control mechanism controls the feeding drive mechanism to move the guide 30 from the second position to the first position. The feeding drive mechanism then generates a post-feeding signal (such as...). Figure 4d (As shown). At this time, the feed port 341 is located at the feed position 301, and the discharge port 342 is disengaged from the assembly position 302.

[0064] (5) The control mechanism controls the first drive unit 12 to operate according to the feeding post position signal, so that the first drive unit 12 drives the first push rod 11 to slide back and reset in the spring conveying channel 34, and the spring push mechanism 10 generates a push post position signal (such as...). Figure 4e As shown), at this time, the feed port 341 is located at the feed position 301, and the first push rod 11 retracts to the side of the feed position 301 away from the assembly position 302, completing the preparation work for the next moving spring assembly.

[0065] refer to Figure 8The present invention also discloses a relay push rod assembly assembly device 1, including a conveying mechanism, a moving spring assembly mechanism 100, a moving spring assembly mechanism 5, and a detection mechanism. The conveying mechanism is used to sequentially convey the fixing fixture 103 of the frame 203 of the push rod assembly 200 to the loading station 601, the moving spring assembly station 602, the moving spring assembly station 603, and the detection station 604. The moving spring assembly mechanism 100 is installed at the moving spring assembly station 602, and the moving spring assembly mechanism 5 is installed at the moving spring assembly station 603 and is used to insert the moving spring 205 into the frame 203. The detection mechanism detects the assembly of the push rod assembly 200 at the detection station 604.

[0066] The conveying mechanism includes a working disc 2 and a rotary motor 3. The working disc 2 is equipped with a fixing fixture 103 for positioning the push rod assembly 200 at positions corresponding to the loading station 601, the moving spring assembly station 602, the moving spring assembly station 603, and the inspection station 604. The rotary motor 3 drives the working disc 2 to rotate, so that the working disc 2 rotates along the loading station 601, the moving spring assembly station 602, the moving spring assembly station 603, and the inspection station 604, thereby conveying the fixing fixture 103 sequentially to the loading station 601, the moving spring assembly station 602, the moving spring assembly station 603, and the inspection station 604.

[0067] During operation, firstly, the loading device installs the frame 203, which includes the magnetic conductor 202 and the push rod 201, into the fixed fixture 103 at the loading station 601. The rotary motor 3 drives the working disc 2 to rotate one stroke, causing the fixed fixture 103, which contains the magnetic conductor 202, the push rod 201, and the frame 203, to rotate from the loading station 601 to the moving spring assembly station 602. The moving spring assembly mechanism 100 is installed at the moving spring assembly station 602 and is used to compress and install the moving spring 204 into the frame 203 at the moving spring assembly station 602, so that the moving spring 204 abuts against the top of the frame 203 and the magnetic conductor 202. Next, the rotary motor 3 drives the working plate 2 to rotate one stroke, causing the fixture 103, which contains the magnetic conductor 202, push rod 201, frame 203, and movable spring 204, to rotate from the movable spring assembly station 602 to the movable spring assembly station 603. The movable spring assembly mechanism 5 is installed at the movable spring assembly station 603 to install the movable spring 205 into the frame 203, so that the movable spring 205 is inserted between the bottom of the frame 203 and the magnetic conductor 202, completing the assembly of the push rod assembly 200. Next, the rotary motor 3 drives the working plate 2 to rotate one stroke, causing the fixture containing the complete push rod assembly 200 to rotate from the movable spring assembly station 603 to the inspection station 604. The inspection mechanism inspects the assembly status of the push rod assembly 200 at the inspection station 604 to determine whether the workpiece is qualified.

[0068] In this invention, a laser probe is used to detect whether the movable spring 205 and the movable spring 204 in the push rod assembly 200 are installed in place to determine whether the push rod assembly 200 is assembled. Of course, a camera mechanism can also be used as a detection mechanism to detect the assembly status of the push rod assembly 200.

[0069] refer to Figure 9 The movable spring assembly mechanism 5 is used to insert the movable spring 205 between the magnetic conductor 202 and the bottom of the frame 203 at the assembly position 501. It includes a support platform 500, a pressing mechanism 51, a lifting mechanism 52, and a pushing mechanism 53. The support platform 500 can support the frame 203 at the assembly position 501. The pressing mechanism 51 is located above the assembly position 501 and can press down on the top of the frame 203 at the assembly position 501. The lifting mechanism 52 is located below the assembly position 501 and has a push rod 521 that can simultaneously push upwards on the bent arm 2021 in the magnetic conductor 202. The pushing mechanism 53 includes a sliding track 531 for the movable spring 205 to slide along a first direction, a pushing member 532 that can push the movable spring 205 to slide in the sliding track 531, and a pushing drive member 533 that drives the pushing member 532 to extend and retract along the first direction. The sliding track 531 connects the loading position 502 and the assembly position 501, so that the pushing drive member 533 can drive the pushing member 532 to push the movable spring 205 from the loading position 502 to the assembly position 501 along the sliding track 531.

[0070] During operation, (1) the support platform 500 supports the frame 203 on the assembly position 501, and the pressing mechanism 51 presses down on the frame 203 at the assembly position 501 to cooperate with the support platform 500 in positioning the frame 203. The frame 203 is equipped with a moving spring 204 and a magnetic guide 202. (2) The lifting mechanism 52 pushes the two bent arms 2021 of the magnetic guide 202 upward in sync, so that the magnetic guide 202 is relatively far away from the bottom of the frame 203. The moving spring 204 is compressed accordingly, and there is a gap between the magnetic guide 202 and the bottom of the frame 203 for the moving spring 205 to be inserted. (3) The feeding mechanism completes feeding at the feeding position 502 in front of the sliding rail 531. The pushing drive 533 controls the pushing part 532 to move so that the pushing part 532 moves from the end of the feeding position 502 away from the assembly position 501 to the assembly position 501. The pushing part 532 then pushes the moving spring 205 from the feeding position 502 along the sliding rail 531 to the assembly position 501. After the pushing is in place, the moving spring 205 is inserted into the frame 203 and located between the bottom of the frame 203 and the magnetic conductor 202. (4) The pushing drive 533 controls the pushing part 532 to reset. The lifting mechanism 52 controls the pushing rod 521 to move downward to reset. The moving spring 204 resets to push the magnetic conductor 202 downward so that the moving spring 205 is clamped between the bottom of the frame 203 and the magnetic conductor 202. (5) The push rod 521 of the lifting mechanism 52 is reset to release the fixed fixture 103, and the rotary motor 3 can move the fixed fixture 103 assembled by the moving spring 205 to the next station.

[0071] refer to Figure 9 The pressing mechanism 51 includes a first driving member and a pressing block 511. The first driving member is connected to the pressing block 511 and drives the pressing block 511 to move up and down so that the pressing block 511 touches or releases the top of the frame 203 at the assembly position 501.

[0072] refer to Figure 9 The lifting mechanism 52 includes a second driving member 522 and a pushing member 523. The second driving member 522 is connected to the pushing member 523 to drive the pushing member 523 to move up and down. The pushing member 523 has two pushing rods 521 that are positioned opposite to the two bent arms 2021 of the magnetic conductor 202 at the assembly position 501 and can push the bent arms 2021. When the pushing member 523 rises, it can drive the two bent arms 2021 to rise synchronously.

[0073] refer to Figure 9The sliding track 531 has a feed inlet 542 and a discharge outlet. The feed inlet 542 is connected to the loading position 502, and the discharge outlet is located opposite and adjacent to the assembly position 501 along a first direction. Specifically, in this embodiment, the loading position 502 is integrally formed with the sliding track 531, and the loading position 502 is formed on the sliding track 531 and located outside the feed inlet 542. The pushing drive member 533 is connected to the pushing block and drives the pushing member 532 to slide along the sliding track 531 along the first direction. The pushing member 532 pushes the movable spring 205 to slide in the sliding track 531 and slide along the first direction to the assembly position 501. There is a gap between the discharge outlet and the assembly position 501, and the gap is less than half the length of the movable spring.

[0074] Specifically, the sliding track 531 does not have a limiting wall above the feed port 542, and the top of the section of the sliding track 531 near the discharge port has a limiting wall 534, so that the discharge port of the sliding track 531 limits the moving spring 205 in the height direction.

[0075] refer to Figure 8 A moving spring positioning detection window is provided on the pressing block 511 of the pressing mechanism 51. A moving spring positioning detector is installed on the moving spring positioning detection window and detects whether the moving spring 205 is inserted into the correct position through the moving spring positioning detection window. A moving spring feeding detection window is provided on the bottom wall of the feeding position 502. A moving spring feeding detector is installed on the moving spring feeding detection window and detects whether the moving spring 205 is fed to the feeding position 502, so as to control the action of the pushing drive 533. When the moving spring feeding detector detects that the moving spring 205 is fed, the pushing drive 533 drives the pushing member 532 to slide forward along the sliding track 531 in the first direction, so that the pushing member 532 pushes the moving spring 205 to slide in the sliding track 531 and slide along the first direction to the assembly position 501.

[0076] Of course, the structure of the moving reed assembly mechanism 5 is not limited to this, and other moving reed plug-in devices used for relays can also be used to assemble the moving reed 205.

[0077] In this embodiment, the first drive unit 12, the second drive unit 43, and other drive components are all telescopic cylinders. Of course, motors or other devices can also be used as power sources to replace telescopic cylinders.

[0078] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
