[0029] It has been found through research that the following problems exist in the assembly equipment in the related art: First, in the assembly mode of the linear conveyor line cooperating with the manipulator for grasping, the angular error between the circumferential angle of the heat dissipation pipe socket and the orientation matching angle of the pins of the connector body is about 5°; second, the coaxiality deviation between the heat dissipation pipe and the connector body is too large, resulting in scratches on the connector body when the heat dissipation pipe is sleeved on the connector body; third, when the heat dissipation pipe falls into the feeding pipe, the heat dissipation pipe is deformed due to collision. These problems seriously affect the assembly accuracy of the connector for photovoltaic micro-inverters.

[0030] Based on the above research, the embodiments of the present disclosure provide a connector assembly device and an assembly process for a photovoltaic micro-inverter.

[0031] Regarding the defects existing in the above solutions, they are all the results obtained by the inventors through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article for the above problems should all be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0032] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] Please refer to Figure 1 and Figure 2 , at least one embodiment provides a connector assembly device for a photovoltaic micro-inverter, including: a connector body assembly mechanism 100 for assembling the connector body; a conveying mechanism 200 for conveying the assembled connector body; a first assembly mechanism 300 disposed on the side of the conveying mechanism 200 and used to sleeved the socket 510 on the heat dissipation pipe 500 on the connector body after adjusting the angle; a second assembly mechanism 400 disposed on the side of the conveying mechanism 200 and used to sleeved the cover on the connector body.

[0035] Among them, the connector body assembly mechanism 100 is provided with 4 assembly stations, namely, a feeding station for feeding the base body 610; a pin assembly station for inserting the pins 620 into the base body 610; an insulating block assembly station for inserting the insulating block into the base body; a discharging station for feeding the assembled connector body 600 into the conveying mechanism 200; the four assembly stations are switched by a rotating disk.

[0036] Specifically, the feeding station sleeved the base body 610 on the rotating disk through an external robotic arm; the pin assembly station completed the conveying and assembly of the pins 620 through the vibration feeding and the pushing of the cylinder; the insulating block assembly station completed the conveying and assembly of the insulating block through the vibration feeding and the pushing of the cylinder.

[0037] The first assembly mechanism 300 includes: a vibrating feeder tray 310 for feeding the heat dissipation tubes 500; a feeding pipe 320 with a feeding port 323 opened at the top and communicating with the conveying track of the vibrating feeder tray 310; a pushing component 330, the pushing part 331 of which is inserted into the feeding pipe 320; wherein, a plurality of adjusting plates 321 are arranged at intervals along the circumferential direction of the inner wall of the feeding pipe 320, and are used to adjust the angle of the socket 510 on the heat dissipation tube 500 under the push of the pushing component 330, and push the heat dissipation tube 500 into the conveying mechanism 200 from the feeding pipe 320 and sleeved on the connector body.

[0038] Through the coordinated action of the movement track of the pushing component 330 and the adjusting plate 321 in the feeding pipe 320, the axial movement and circumferential angle adjustment of the heat dissipation tube 500 are simultaneously completed in a single pushing action (as Figure 8 shown), replacing the method of using a manipulator for angle adjustment in the related art, reducing the directional matching angle error from ±5° to ±1.2°, realizing the precise alignment of the socket 510 of the heat dissipation tube 500 and the connector body, and improving the assembly accuracy of the connector for the photovoltaic micro-inverter while improving the assembly efficiency.

[0039] Please refer to Figure 3 and Figure 4 As shown, a guiding groove 322 is arranged on the inner wall of the feeding pipe 320; a sliding block adapted to the guiding groove 322 is arranged on the pushing part 331; when the pushing part 331 slides along the guiding groove 322, it drives the socket 510 of the heat dissipation tube 500 to rotate until the adjusting plate 321 is aligned with the socket 510 of the heat dissipation tube 500, and the burrs on the heat dissipation tube 500 are removed.

[0040] The guiding groove 322 and the sliding block cooperate to form a mechanical limiting track. When the pushing part 331 slides, it forcibly drives the heat dissipation tube 500 to rotate, eliminating the downtime required for manual angle adjustment. At the same time, during the alignment process of the adjusting plate 321 and the socket 510 of the heat dissipation tube 500, the burrs are removed synchronously, saving the subsequent deburring process.

[0041] It should be noted that the burrs in the feeding pipe 320 need to be cleaned regularly.

[0042] Please refer to Figure 4 As shown, the guiding groove 322 includes: a straight segment 322a and an arc segment 322b; the straight segment 322a is communicated with the arc segment 322b; when the pushing part 331 slides along the arc segment 322b of the guiding groove 322, it drives the socket 510 of the heat dissipation tube 500 to rotate.

[0043] When the pushing part 331 slides along the straight line segment 322a of the guiding groove 322, it pushes the heat dissipation pipe 500 to abut against the adjusting plate 321. When sliding along the arc segment 322b of the guiding groove 322, it drives the heat dissipation pipe 500 to rotate Figure 4 in the direction shown by F in

[0044] Please refer to Figure 4 and Figure 5 . The pushing part 331 includes: a pushing head 331a, which is provided with a circular groove 331a1 along the axial direction of the feeding pipe 320; a buffer plate 331b, which is elastically connected to the circular groove 331a1 through a return spring 331c; and when the buffer plate 331b is in a natural state, the side wall of the buffer plate 331b extends out of the circular groove 331a1 and is oppositely arranged with the feeding port 323 of the feeding pipe 320. When the heat dissipation pipe 500 falls into the feeding pipe 320 from the feeding port 323, it is buffered by the side wall of the buffer plate 331b, reducing the impact of the heat dissipation pipe 500.

[0045] It should be noted that the buffer plate 331b is made of elastic rubber material, and the buffer plate 331b elastically expands and contracts through the return spring 331c to absorb the impact kinetic energy of the heat dissipation pipe 500 falling from the vibrating feeding tray 310, preventing the heat dissipation pipe 500 from deforming.

[0046] Specifically, the buffer plate 331b is frustum-shaped; and the upper bottom surface of the buffer plate 331b extends out of the circular groove 331a1, and the lower bottom surface of the buffer plate 331b extends into the circular groove 331a1.

[0047] Among them, the diameter of the upper bottom surface of the buffer plate 331b is R1; the diameter of the lower bottom surface of the buffer plate 331b is R2; the inner diameter of the heat dissipation pipe 500 is r; where R1 < r < R2, and the units of R1 and R2 are mm; when the pushing part 331 slides along the guiding groove 322, the upper bottom surface of the buffer plate 331b is inserted into the heat dissipation pipe 500, making the heat dissipation pipe 500 coaxial with the feeding pipe 320.

[0048] It should be noted that the buffer plate 331b is coaxial with the feeding pipe 320. When the buffer plate 331b is inserted into the inner hole of the heat dissipation pipe 500, the heat dissipation pipe 500 is made coaxial with the buffer plate 331b, and then the heat dissipation pipe 500 is made coaxial with the feeding pipe 320, so that the inner diameter of the feeding pipe 320 can be increased, reducing the scratches caused by the friction between the heat dissipation pipe 500 and the feeding pipe 320.

[0049] With the dimensional constraint of R1 < r < R2, when pushing the material, the upper bottom surface of the buffer plate 331b is inserted into the inner hole of the heat dissipation tube 500, and forced correction is carried out to make the heat dissipation tube 500 coaxial with the buffer plate 331b, that is, the heat dissipation tube 500 is coaxial with the feeding tube 320, improving the accuracy of the angle adjustment between the socket 510 of the heat dissipation tube and the adjustment plate 321.

[0050] Please refer to Figure 5 and Figure 6 , the pushing head 331a extends outwards to form an arc-shaped supporting plate 331d; the arc-shaped supporting plate 331d is disposed opposite to the feeding port 323 of the feeding tube 320. The arc-shaped supporting plate 331d is disposed opposite to the feeding port 323 to receive the heat dissipation tube 500 that has not completely fallen into the feeding tube 320 and prevent it from falling obliquely.

[0051] Please refer to Figure 2 and Figure 4 , the pushing assembly 330 further includes: a pushing cylinder 333; a push rod 332 connected to the piston rod of the pushing cylinder 333; the push rod 332 is rotatably connected to the pushing part 331. The pushing cylinder 333 provides a constant pushing force, and the push rod 332 is rotatably connected to the pushing part 331 to adapt to the trajectory change of the arc segment 322b of the guiding groove 322 and avoid jamming.

[0052] Please refer to Figure 2 , the conveying mechanism 200 includes: a linear driving part 210; a driving block 220 disposed on the linear driving part 210; a clamping part 230 disposed on the driving block 220 and used for clamping the connector body.

[0053] As Figure 7 shown, the linear driving part 210 drives the clamping part 230 to move, so that the clamping part 230 is opposite to the feeding tube 320, facilitating the pushing part 331 to push the heat dissipation tube 500 from the feeding tube 320 onto the clamping part 230 and sleeving it on the connector body 600.

[0054] Please refer to Figure 10 , at least one embodiment further provides an assembly process applied to the connector assembly equipment for the photovoltaic micro-inverter as described above. The assembly process includes: Step S1, assembling the connector body through the connector body assembly mechanism 100.

[0055] Step S2, after the conveying mechanism 200 takes out the assembled connector body, it is sent to the first assembly mechanism 300.

[0056] Step S3, adjusting the angle of the socket 510 on the heat dissipation tube 500 through the first assembly mechanism 300 and then sleeving it on the connector body.

[0059] In step S6, the conveying mechanism 200 takes out the assembled connector body and sends it to the blanking channel to complete the assembly.

[0060] In summary, the present invention provides a connector assembly device and an assembly process for a photovoltaic micro-inverter. Among them, the connector assembly device for a photovoltaic micro-inverter includes: a connector body assembly mechanism 100 for assembling the connector body; a conveying mechanism 200 for conveying the assembled connector body; a first assembly mechanism 300 disposed on the side of the conveying mechanism 200 and used for sleeving the socket 510 on the heat dissipation pipe 500 on the connector body after adjusting the angle; a second assembly mechanism 400 disposed on the side of the conveying mechanism 200 and used for sleeving the cover on the connector body. The first assembly mechanism 300 includes: a vibrating feeding tray 310 for feeding the heat dissipation pipe 500; a feeding pipe 320 with a feeding port 323 opened at the top and communicating with the conveying rail of the vibrating feeding tray 310; a pushing component 330 whose pushing part 331 is inserted into the feeding pipe 320; wherein, a plurality of adjusting plates 321 are circumferentially spaced along the inner wall of the feeding pipe 320 and are used for adjusting the angle of the socket 510 on the heat dissipation pipe 500 under the push of the pushing component 330, pushing the heat dissipation pipe 500 from the feeding pipe 320 into the conveying mechanism 200 and sleeving it on the connector body. Through the cooperative action of the movement track of the pushing component 330 and the adjusting plates 321 in the feeding pipe 320, the axial movement and circumferential angle adjustment of the heat dissipation pipe 500 are completed simultaneously in a single pushing action, replacing the method of using a manipulator for angle adjustment in the related art, reducing the directional matching angle error from ±5° to ±1.2°, realizing the precise alignment of the socket 510 of the heat dissipation pipe 500 and the connector body, and improving the assembly efficiency and the assembly precision of the connector for the photovoltaic micro-inverter.
