Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and specifically relates to a device for assembling connectors, and more particularly to a connector assembly device for photovoltaic micro-inverters and an assembly process thereof. Background Art

[0002] In the field of automated assembly of connectors for photovoltaic micro-inverters, the high-precision connection between the connector body and the heat pipe is a core process difficulty.

[0003] In related technologies, assembly equipment mostly adopts an assembly mode of straight conveyor lines combined with robotic gripping. However, with the miniaturization trend of micro-inverter connectors, the directional matching requirements of the circumferential angle of the heat pipe socket and the connector body pins are more stringent. The robotic arm visual positioning system of existing assembly equipment is difficult to take into account the requirements of high-speed operation and angle fine-tuning, resulting in excessively large directional matching angle errors between the heat pipe socket and the connector body pins, which ultimately leads to too low assembly accuracy of connectors for photovoltaic micro-inverters.

[0004] Therefore, how to improve the assembly accuracy of connectors for photovoltaic micro-inverters while ensuring assembly efficiency is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

DETAILED DESCRIPTION

[0068] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0069] In this document, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or that a third component may be interposed between the first component and the second component. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0070] As used herein, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," "directly attached to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0071] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0072] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an" and "the" may also be intended to include plural forms, unless otherwise clearly indicated herein. The terms "comprise", "include" and "have" are inclusive and therefore specify the presence of features, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components and / or combinations thereof. The method steps, processes and operations described herein should not be interpreted as necessarily requiring them to be performed in the particular order discussed or shown, unless specifically identified as an execution order. Additional or alternative steps may be adopted.

[0073] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects, or designs. Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0074] After research, it was found that the assembly equipment in the related technology has the following problems:

[0075] First, the linear conveyor assembly system, coupled with robotic gripping, resulted in an angular error of approximately 5° between the circumferential angle of the heat pipe socket and the orientation of the connector pins. Second, the coaxiality deviation between the heat pipe and the connector body was too large, causing scratches on the connector body when the heat pipe was installed. Third, the heat pipe deformed due to collision when it fell into the feed tube. These issues seriously affected the assembly accuracy of the connector for photovoltaic micro-inverters.

[0076] Based on the above research, an embodiment of the present disclosure provides a connector assembly device and assembly process for photovoltaic micro-inverters. By replacing visual positioning with mechanical limiting, the directional matching angle error is reduced from ±5° to ±1.2° while ensuring assembly efficiency, thereby improving the assembly accuracy of photovoltaic micro-connectors.

[0077] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0078] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0079] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0080] See also 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, which is used to assemble the connector body; a conveying mechanism 200, which is used to convey the assembled connector body; a first assembly mechanism 300, which is arranged on the side of the conveying mechanism 200 and is used to adjust the angle of the socket 510 on the heat pipe 500 and then put it on the connector body; a second assembly mechanism 400, which is arranged on the side of the conveying mechanism 200 and is used to put a cover on the connector body.

[0081] Among them, the connector body assembly mechanism 100 is provided with 4 assembly stations, namely, a loading station for loading the base body 610; a pin assembly station for inserting the pin 620 into the base body 610; an insulating block assembly station for inserting the insulating block into the base body; and a unloading station for feeding the assembled connector body 600 into the conveying mechanism 200; the four assembly stations are switched by a rotating disk.

[0082] Specifically, the loading station places the base body 610 on the rotating disk through an external robotic arm; the pin assembly station completes the transportation and assembly of the pins 620 through vibration feeding and cylinder pushing; the insulating block assembly station completes the transportation and assembly of the insulating block through vibration feeding and cylinder pushing.

[0083] The first assembly mechanism 300 includes: a vibrating feed tray 310, which is used to load the heat dissipation tube 500; a feed tube 320, a top of which is provided with a feed port 323 connected to the conveying rail of the vibrating feed tray 310; a pushing assembly 330, a pushing portion 331 of which is inserted into the feed tube 320; wherein, the inner wall of the feed tube 320 is provided with a plurality of adjustment plates 321 at intervals along the circumferential direction, and is used to adjust the angle of the socket 510 on the heat dissipation tube 500 under the push of the pushing assembly 330, push it from the feed tube 320 to the conveying mechanism 200, and put it on the connector body.

[0084] Through the motion trajectory of the pushing assembly 330 and the coordinated action of the adjustment plate 321 in the feeding tube 320, the axial movement and circumferential angle adjustment of the heat dissipation tube 500 are simultaneously completed in a single pushing action (such as Figure 8 As shown in the figure, instead of using a manipulator to adjust the angle in the related art, the directional matching angle error is reduced from ±5° to ±1.2°, and the socket 510 of the heat pipe 500 and the connector body are precisely aligned, thereby improving the assembly efficiency and the assembly accuracy of the connector for photovoltaic micro-inverters.

[0085] See also Figure 3 and Figure 4 The inner wall of the feeding tube 320 is provided with a guide groove 322; the pushing portion 331 is provided with a slider adapted to the guide groove 322; when the pushing portion 331 slides along the guide groove 322, it drives the socket 510 of the heat dissipation pipe 500 to rotate until the adjustment plate 321 is aligned with the socket 510 of the heat dissipation pipe 500, thereby removing the burrs on the heat dissipation pipe 500.

[0086] The guide groove 322 cooperates with the slider to form a mechanical limit track. When the pusher part 331 slides, it forces the heat pipe 500 to rotate, eliminating the downtime required for manual angle adjustment. At the same time, during the alignment process of the adjustment plate 321 and the heat pipe 500 socket 510, burrs are removed synchronously, eliminating the subsequent deburring process.

[0087] It should be noted that the burrs in the feeding tube 320 need to be cleaned regularly.

[0088] See also Figure 4 The guide groove 322 includes: a straight segment 322a and an arc segment 322b; the straight segment 322a is connected to the arc segment 322b; when the pushing portion 331 slides along the guide groove 322 along the arc segment 322b, the socket 510 of the heat pipe 500 is driven to rotate.

[0089] When the pusher 331 slides along the straight section 322a of the guide groove 322, it pushes the heat pipe 500 to abut against the adjustment plate 321. When the pusher 331 slides along the arc section 322b of the guide groove 322, it drives the heat pipe 500 along the adjustment plate 321. Figure 4 Turn in the direction indicated by F to complete the angle adjustment.

[0090] See also Figure 4 and Figure 5 The pushing portion 331 includes: a pushing head 331a, which is provided with a circular groove 331a1 along the axial direction of the feeding tube 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 from the circular groove 331a1 and is arranged opposite to the feed port 323 of the feeding tube 320; when the heat dissipation tube 500 falls into the feeding tube 320 from the feed port 323, it is buffered by the side wall of the buffer plate 331b, thereby reducing the collision of the heat dissipation tube 500.

[0091] It should be noted that the buffer plate 331b is made of elastic rubber. The buffer plate 331b is elastically expanded and contracted by the return spring 331c to absorb the impact kinetic energy of the heat dissipation pipe 500 falling from the vibrating feed tray 310 and prevent the heat dissipation pipe 500 from deforming.

[0092] Specifically, the buffer plate 331b is in a truncated cone shape; and the upper bottom surface of the buffer plate 331b extends from the circular groove 331a1, and the lower bottom surface of the buffer plate 331b extends into the circular groove 331a1.

[0093] 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 tube 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 tube 500, so that the heat dissipation tube 500 is coaxial with the feeding tube 320.

[0094] It should be noted that the buffer plate 331b is coaxial with the feeding tube 320. When the buffer plate 331b is inserted into the inner hole of the heat dissipation tube 500, the heat dissipation tube 500 is coaxial with the buffer plate 331b, and then the heat dissipation tube 500 is coaxial with the feeding tube 320, so that the inner diameter of the feeding tube 320 can be increased, and scratches caused by friction between the heat dissipation tube 500 and the feeding tube 320 can be reduced.

[0095] Through the dimensional constraint R1 < r < R2, the upper bottom surface of the buffer plate 331b is inserted into the inner hole of the heat dissipation tube 500 during pushing, and forced correction is performed 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, and the accuracy of the angle adjustment between the socket 510 of the heat dissipation tube and the adjusting plate 321 is improved.

[0096] 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 arranged opposite to the feeding port 323 of the feeding tube 320. The arc-shaped supporting plate 331d is arranged opposite to the feeding port 323 to承接 the heat dissipation tube 500 that has not completely fallen into the feeding tube 320 and prevent it from falling obliquely.

[0097] 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.

[0098] Please refer to Figure 2 , the conveying mechanism 200 includes: a linear driving part 210; a driving block 220 arranged on the linear driving part 210; a clamping part 230 arranged on the driving block 220 and used for clamping the connector body.

[0099] As Figure 7As shown, the linear drive part 210 drives the clamping part 230 to move, so that the clamping part 230 is opposite to the feeding tube 320, so that the pushing part 331 pushes the heat dissipation tube 500 from the feeding tube 320 onto the clamping part 230 and sleeves it on the connector body 600.

[0100] See also Figure 10 At least one embodiment further provides an assembly process for the connector assembly device for the photovoltaic micro-inverter as described above, the assembly process comprising:

[0101] Step S1 , assembling the connector body by the connector body assembly mechanism 100 .

[0102] In step S2 , the conveying mechanism 200 takes out the assembled connector body and delivers it to the first assembly mechanism 300 .

[0103] In step S3 , the socket 510 on the heat pipe 500 is adjusted in angle by the first assembly mechanism 300 and then mounted on the connector body.

[0104] In step S4 , the conveying mechanism 200 takes out the connector body with the heat pipe 500 mounted thereon and conveys it to the second assembly mechanism 400 .

[0105] Step S5 : The cover is mounted on the connector body by the second assembly mechanism 400 .

[0106] In step S6, the conveying mechanism 200 takes out the assembled connector body and sends it to the unloading channel to complete the assembly.

[0107] In summary, the present invention provides a connector assembly device for a photovoltaic micro-inverter and an assembly process thereof, wherein the connector assembly device for a photovoltaic micro-inverter includes: a connector body assembly mechanism 100, which is used to assemble the connector body; a conveying mechanism 200, which is used to convey the assembled connector body; a first assembly mechanism 300, which is arranged on the side of the conveying mechanism 200, and is used to adjust the angle of the socket 510 on the heat pipe 500 and then put it on the connector body; a second assembly mechanism 400, which is arranged on the side of the conveying mechanism 200, and is used to put a cover on the connector body. The first assembly mechanism 300 includes: a vibrating feed tray 310, which is used to load the heat dissipation tube 500; a feed tube 320, a top of which is provided with a feed port 323 connected to the conveying rail of the vibrating feed tray 310; a pushing assembly 330, a pushing portion 331 of which is inserted into the feed tube 320; wherein, the inner wall of the feed tube 320 is provided with a plurality of adjustment plates 321 at intervals along the circumferential direction, and is used to adjust the angle of the socket 510 on the heat dissipation tube 500 under the push of the pushing assembly 330, push it from the feed tube 320 to the conveying mechanism 200, and put it on the connector body. Through the coordinated action of the motion trajectory of the pushing assembly 330 and the adjustment plate 321 in the feeding tube 320, the axial movement and circumferential angle adjustment of the heat pipe 500 are simultaneously completed in a single pushing action, replacing the method of using a manipulator for angle adjustment in related technologies, reducing the directional matching angle error from ±5° to ±1.2°, and achieving precise alignment of the socket 510 of the heat pipe 500 and the connector body, thereby improving the assembly efficiency and the assembly accuracy of the connector for photovoltaic micro-inverters.
