[0034] At present, during the assembly process of the push rod assembly, the operator uses tweezers to manually install the spring 3 into the frame 2. During the assembly process, the tweezers are needed to compress the spring 3. Due to the different forces applied by different operators or at different times, the spring 3 may be twisted and deformed, or even damaged and unable to rebound due to excessive compression force. During the assembly process, since external force is required to press, the spring 3 may occasionally collapse, resulting in a waste of assembly time. For this reason, the present application proposes a relay assembly device.

[0035] like Figure 1-Figure 3 As shown, the relay assembly device according to the embodiment of the present application includes a frame 10 , a spring pressure plate 20 and a first pushing mechanism 30 .

[0036] Specifically, a positioning groove 11 is provided on the frame 10, and the positioning groove 11 is used to fix the frame 2 of the push rod assembly of the relay. The frame 10 also defines a first conveying channel, which is connected to the positioning groove 11. The first conveying channel is provided with a loading groove 12, and the loading groove 12 is used to place the spring 3; the spring pressure plate 20 can be movably arranged on the frame 10, and a spring pressure head 21 is provided on the spring pressure plate 20. The spring pressure plate 20 has a first position and a second position. When the spring pressure plate 20 is in the first position, it avoids the loading groove 12. When the spring pressure plate 20 is in the second position, the spring pressure head 21 is embedded in the loading groove 12; the first pushing mechanism 30 is movable in the first conveying channel to push the spring 3 from the loading groove 12 to the positioning groove 11. Figure 1-Figure 3 The spring pressure plate 20 is shown in the second position.

[0037] When the relay assembly equipment is used to assemble the spring 3 of the push rod assembly, the frame 2 is first placed in the positioning groove 11, the spring pressure plate 20 is moved to the first position, and the spring 3 is placed in the feeding groove 12. After that, the spring pressure plate 20 is moved to the second position, and the spring pressure head 21 is embedded in the feeding groove 12 to compress the spring 3. The first pushing mechanism 30 pushes the compressed spring 3 to slide in the first conveying channel until the spring 3 is stuck in the frame 2 located in the positioning groove 11. Figure 2 As shown, the spring 3 shown by the dotted line in the frame 2 is the position to which the spring 3 on the left side finally moves.

[0038] It can be understood that the positioning groove 11 is used to place the frame 2, and can limit the frame 2, so that the spring 3 is easier to align with the frame 2, avoiding the displacement of the frame 2 and increasing the difficulty of assembly; when the spring pressure plate 20 is in the first position, it avoids the loading groove 12, so that the spring 3 can be conveniently placed in the loading groove 12. In the process of the spring pressure plate 20 moving to the second position, the spring pressure head 21 gradually compresses the spring 3 and is finally embedded in the loading groove 12, thereby achieving the final compression of the spring 3, making it convenient for the spring 3 to shorten its length and completely enter the first conveying channel.

[0039] In addition, since the spring pressure head 21 can completely press the spring 3 into the first conveying channel, the straight-line distance between the loading trough 12 and the positioning groove 11 can be set appropriately and does not need to be too long, which can shorten the moving distance of the spring 3 in the first conveying channel and improve assembly efficiency.

[0040] The first position and the second position are used to describe two states of the spring pressure plate 20, and there is no restriction on the specific position of the spring pressure plate 20 when it is in the first position. It is only necessary to make the spring pressure plate 20 movable on the frame 10 to avoid the feeding slot 12, and to make the spring pressure head 21 be able to be embedded in the feeding slot 12 to compress the spring 3. The spring pressure plate 20 can be assembled detachably from the frame 10, for example, directly covered on the frame 10 and directly removed from the frame 10 after use; it can also be that the spring pressure plate 20 is hingedly connected to the frame 10; the spring pressure plate 20 is slidably connected to the frame 10, etc.

[0041] According to the relay assembly equipment of the embodiment of the present application, the spring 3 is compressed by the spring pressure head 21, so that the compressed spring 3 can enter the first conveying channel and be accurately pushed into the frame 2 located in the positioning groove 11 by the first pushing mechanism 30. During this assembly process, the compression force of the spring 3 can be controlled to avoid the spring 3 from being twisted and deformed due to improper force, thereby extending the service life of the relay. At the same time, the spring 3 is installed by using the relay assembly equipment, and the operation time is short, thereby improving the installation efficiency.

[0042] like Figure 1-Figure 3As shown, according to the relay assembly equipment of the embodiment of the present application, the first pushing mechanism 30 includes a first main body 31, the first main body 31 is located in the first conveying channel, the first main body 31 includes a first pushing portion 311 configured as an arc shape, the opening of the first pushing portion 311 faces the positioning groove 11, and the first pushing portion 311 is used to push the spring 3.

[0043] It is understandable that the first push portion 311 is configured to be an arc shape that can adapt to the shape of the spring 3, and fit better when in contact, so as to prevent the spring 3 from being skewed when the spring 3 is pushed in the first conveying channel. It is understandable that the opening of the first push portion 311 faces the positioning groove 11, so that the opening of the first push portion 311 is locked in the spring 3 and it is also convenient for the spring 3 to escape from the opening.

[0044] A boss is usually provided inside the frame 2 of the push rod assembly to limit the spring 3 and prevent the spring 3 from falling off the frame 2. During the actual assembly process, if the compression force is not appropriate, the spring 3 may scratch the boss. For this reason, the present application proposes a relay assembly device.

[0045] like Figure 2-Figure 4 As shown, in some embodiments, a boss is provided in the frame 2, and the first pushing mechanism 30 also includes a second main body 33 stacked below the first main body 31, and the second main body 33 includes a second push portion 331, and the second push portion 331 extends beyond the contour edge of the first push portion 311 on the side facing the positioning groove 11, and the height of the top surface of the second push portion 331 is not lower than the height of the top surface of the boss. When the spring 3 is placed in the feeding trough 12, the part of the second push portion 331 that exceeds the first push portion 311 on the side facing the positioning groove 11 is located below the spring 3, which is used to support the spring 3, and the height of the top surface of the second push portion 331 is not lower than the height of the top surface of the boss, so that when the second push portion 331 supports the spring 3 to be inserted into the frame 2, the spring 3 can be better transferred to the boss to prevent the spring 3 from scratching the boss.

[0046] The height of the top surface of the second push portion 331 is not lower than the height of the top surface of the boss, including the height of the top surface of the second push portion 331 being higher than the height of the top surface of the boss and the height of the top surface of the second push portion 331 being equal to the height of the top surface of the boss.

[0047] In the actual assembly process, after the spring 3 enters the frame 2, when the first push portion 311 and the second push portion 331 are separated from the spring 3, if the first push portion 311 and the second push portion 331 are pulled out at the same time, when the compressed spring 3 is released, the lack of a limiting structure will cause the spring 3 to be offset, for example, partially stuck on the boss but not completely covered on the boss. For this reason, the present application proposes a relay assembly device.

[0048] In some embodiments, the first main body 31 and the second main body 33 can move relative to each other, so that the first push portion 311 and the second push portion 331 can move relative to each other. In this way, after the spring 3 is pushed into the frame 2, the second push portion 331 is first pulled out from under the spring 3, while the first push portion 311 is still in contact with the spring 3. In the process of releasing the spring 3 from the boss, the spring 3 is limited by the first push portion 311, which ensures accurate alignment and improves installation accuracy and efficiency. After the spring 3 is sleeved on the boss, the first push portion 311 is moved and reset, waiting for the next spring 3 to be loaded into the loading trough 12, and then moves together with the second push portion 331 to push the spring 3 into the frame 2.

[0049] In some embodiments, the first pushing mechanism 30 includes a first power assembly and a second power assembly, the first power assembly is transmission-connected to the first pushing portion 311, the second power assembly is transmission-connected to the second pushing portion 331, and both the first power assembly and the second power assembly include motors or cylinders.

[0050] like Figure 2 and Figure 4 As shown, in some embodiments, the second push portion 331 is configured as an arc shape, and the opening direction of the second push portion 331 is the same as the opening direction of the first push portion 311. When the first pushing mechanism 30 moves to a position where the spring 3 is inserted into the frame 2, the second push portion 331 engages with the boss.

[0051] According to the relay assembly equipment of the embodiment of the present application, when the first pushing mechanism 30 moves to the position where the spring 3 is inserted into the frame 2, the second pushing portion 331 engages with the boss. In this way, when the second pushing portion 331 and the boss engage, it can be determined that the second pushing portion 331 has moved into place, indicating that the spring 3 has been delivered to the desired position. At this time, the second pushing portion 331 can be pulled out. In this way, by utilizing the cooperation between the second pushing portion 331 and the boss, the accuracy of the moving position of the second pushing portion 331 can be improved, the assembly accuracy can be improved, and the product yield rate can be improved.

[0052] like Figure 1-Figure 3 As shown, in some embodiments, a first positioning rod 32 is provided on the first main body 31, and the frame 10 further defines a first guide groove 13, which is connected to the first conveying channel. The first positioning rod 32 is movably clamped in the first guide groove 13, and the first guide groove 13 includes a connected first sub-guide groove 131 and a first limiting groove 132. When the second push portion 331 is engaged with the boss, the first positioning rod 32 is located in the first limiting groove 132.

[0053] According to the relay assembly equipment of the embodiment of the present application, the first guide groove 13 is used to limit and guide the first positioning rod 32, thereby limiting and guiding the first main body 31 during the movement of the first main body 31, thereby improving the position accuracy of the first main body 31 during the movement and reducing the error.

[0054] The first limiting groove 132 is located at an end of the first sub-guide groove 131 close to the positioning groove 11 .

[0055] like Figure 1-Figure 3 As shown, in some embodiments, the relay assembly device further includes a second pushing mechanism 40, and a second conveying channel is further defined on the frame 10. The second pushing mechanism 40 is movable in the second conveying channel to stop the spring 3 when the spring 3 is pushed into the positioning groove 11. In this way, when the first main body 31 pushes the spring 3 to move into the frame 2, the second pushing mechanism 40 also moves in the second conveying channel to stop with the spring 3. In this way, when the second resisting portion 331 is withdrawn, the first resisting portion 311 and the second pushing mechanism 40 are used to limit the spring 3 from both sides, ensuring that the spring 3 is smoothly inserted into the boss when released.

[0056] In some embodiments, the first conveying channel and the second conveying channel are disposed opposite to each other and are respectively located at two ends of the positioning groove 11 .

[0057] In some embodiments, the extension axis of the first delivery channel is co-linear with the extension axis of the second delivery channel.

[0058] like Figure 3-Figure 5 As shown, in some embodiments, the second pushing mechanism 40 includes a third main body 41 and a second positioning rod 42 that are interconnected. The third main body 41 is movably disposed in the second conveying channel. The frame 10 also defines a second guide groove 14. The second positioning rod 42 is movably clamped in the second guide groove 14. The second guide groove 14 includes a connected second sub-guide groove 141 and a second limiting groove 142. The second positioning rod 42 is used to stop the spring 3. When the second positioning rod 42 abuts against the spring 3, the second positioning rod 42 is located in the second limiting groove 142.

[0059] In detail, the second guide groove 14 is connected to the second conveying channel. When the third main body 41 moves in the second conveying channel, the second positioning rod 42 moves in the second guide groove 14. The second positioning rod 42 and the second guide groove 14 are used to limit and position the second positioning rod 42, thereby improving the movement accuracy of the second positioning rod 42. When the second positioning rod 42 abuts against the spring 3, the second positioning rod 42 moves from the second sub-guide groove 141 to the second limiting groove 142.

[0060] It can be understood that the second limiting groove 142 is located at an end of the second sub-guide groove 141 close to the positioning groove 11 .

[0061] like Figure 4 and Figure 5 As shown, in some embodiments, the third main body 41 includes a third push portion 411 configured in an arc shape, the opening of the third push portion 411 faces the positioning groove 11, and the third push portion 411 is used to abut against the spring 3 in the positioning groove 11. When the second positioning rod 42 moves from the second sub-guide groove 141 to the second limiting groove 142, the third push portion 411 abuts against the spring 3 in the frame 2 in the positioning groove 11. In this way, the configuration in an arc shape can increase the contact area between the third push portion 411 and the spring 3, thereby playing a better limiting role on the spring 3 and preventing deviation.

[0062] like Figure 1-Figure 3 As shown, according to the relay assembly device of the embodiment of the present application, the push rod assembly also includes a contact bridge 4 arranged on the frame 2, and a third limiting groove 15 is also provided on the frame 10. When the frame 2 is in the positioning groove 11, the contact bridge 4 is clamped in the third limiting groove 15. In this way, the third limiting groove 15 is used to limit and position the contact bridge 4, so as to improve the stability of the frame 2 installed in the positioning groove 11, avoid the frame 2 from rotating and deviating, ensure the accuracy of the assembly of the frame 2 and the spring 3, and improve the product yield rate.

[0063] like Figure 2-Figure 4 As shown, in some embodiments, the frame 10 includes a cavity bridge plate 16 and two oppositely arranged support members 17, the two support members 17 are respectively arranged at the two ends of the cavity bridge plate 16, and a detachable first positioning plate 18 and a second positioning plate 19 are provided on the cavity bridge plate 16. The cavity bridge plate 16 and the first positioning plate 18 jointly define a first conveying channel, and the cavity bridge plate 16 and the second positioning plate 19 jointly define a second conveying channel. The first positioning plate 18 defines a first guide groove 13, and the second positioning plate 19 defines a second guide groove 14. In this way, the cavity bridge plate 16 is supported by two support members 17, which improves the overall stability of the equipment, and the detachable connection between the cavity bridge plate 16 and the first positioning plate 18 and the detachable connection between the cavity bridge plate 16 and the second positioning plate 19 are used to facilitate the overall disassembly and assembly of the equipment.

[0064] In some embodiments, the first positioning plate 18 and the cavity bridge plate 16 further define a loading chute 12 .
