[0001] The utility model relates to the technical field of photovoltaic component processing, in particular to a junction box taking device. Background Art

[0002] Nowadays, in the processing of photovoltaic modules, after the high-temperature tape on the photovoltaic modules is torn off, in order to install and fix the junction box on the photovoltaic panel, it is usually necessary to use a dispensing device to apply glue on the junction box installation position of the photovoltaic module, and then the junction box is buckled on the photovoltaic module board. The junction box needs to be passed through the bus bar led out from the photovoltaic module board so that the bottom of the junction box is bonded to the glue-coated part. After bonding, the two bus bars inserted in the junction box are bent and welded to form a current path.

[0003] Previous equipment all used to pick up the junction box on the material placement turntable through the junction box picking device on the junction box installation device. The material placement turntable positioned the junction box by setting a limit device. However, when the junction box picking device picked up the junction box and inserted the bus bar for installation, it was affected by the conveying accuracy of the X and Y guide rails. It was difficult for the junction box picking device to accurately match the perforations of the junction box body with the bus bar on the photovoltaic panel, thereby affecting the precise placement of the junction box at the bus bar position, resulting in reduced installation quality and efficiency of the junction box and the bus bar.

[0004] Therefore, how to solve the above-mentioned deficiencies in the prior art and provide a junction box picking device that can improve the installation accuracy of the junction box has become a subject to be studied and solved by the present invention. Utility Model Content

Certain terms used to describe this application are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art regarding the description of this application.

[0061] See attached Figure 1-3 In this embodiment, the junction box is a wireless junction box 100, and a junction box picking device is provided for this purpose, including a box picking mechanism 1 and a seam expansion mechanism 2, which are integrally arranged and can be driven by an xyz three-axis motion platform (not shown in the figure). For a wired junction box 200, a junction box picking device (see Figure 4 ) A coil picking mechanism (not shown in the figure) can be additionally provided.

[0062] The box picking mechanism 1 includes a mounting frame 11 and a box picking assembly 13 connected to the mounting frame 11 via a vibration assembly 12 .

[0063] The box body picking assembly 13 described in this embodiment includes two pairs of clamping structures for picking up the junction box; other embodiments may also include one or more pairs of clamping structures, but the positioning accuracy of a pair of clamping structures for the junction box is limited, and multiple pairs of clamping structures can be set according to junction boxes of different shapes. For example, a hexagonal junction box can be provided with three pairs of clamping structures to accurately position and clamp the junction box.

[0064] In this embodiment, two pairs of gripping structures are driven by a first cylinder 131 and a second cylinder 132, respectively, to grip the junction box in the x and y directions. The first cylinder 131 and the second cylinder 132 are arranged vertically and fixed to each other vertically by a support frame. The first cylinder 131 and the second cylinder 132 are connected to the gripping structures in the four directions via connecting plates.

[0065] One pair of clamping structures includes two clamping blocks 133, which are driven by the first cylinder 131. The two clamping blocks 133 clamp the junction box in the x direction. The clamping blocks 133 can fit the two side surfaces of the junction box in the x direction to accommodate junction boxes of different sizes.

[0066] The box body picking component 13 also includes a first adjustment structure for adjusting the relative positions of the two pairs of clamping structures. The first adjustment structure is a waist-shaped hole (not shown in the figure) on the connecting plate that fixes the two clamping blocks 133. The relative positions of the two clamping blocks 133 can be adjusted through the waist-shaped hole.

[0067] The other pair of gripping mechanisms includes two alignment blocks 134, driven by a second cylinder 132. On opposing surfaces of these blocks 134 are protruding alignment bumps, which align with the y-axis side surfaces of the junction box. These alignment bumps grip and align the junction box in the y-axis. The connecting plates securing these alignment blocks 134 are provided with waist-shaped holes to facilitate adaptive adjustment of the alignment blocks 134 to the position of the junction box.

[0068] The two pairs of clamping structures limit the four end faces of the junction box body, thereby accurately controlling the position of the junction box body and facilitating the subsequent installation of the junction box body.

[0069] like Figure 3 As shown, the vibration component 12 includes a vibration source that provides horizontal vibration for the box body picking component 13. The direction of the horizontal vibration is perpendicular to the insertion and installation direction of the junction box. When the junction box is vertically installed on the photovoltaic module, the horizontal vibration direction is perpendicular to the photovoltaic module.

[0070] In this embodiment, the horizontal vibration includes vibration in the x and y directions, and the vibration source includes a first vibration source that provides horizontal vibration in the y direction for the box body picking component 13 and a second vibration source that provides horizontal vibration in the x direction for the box body picking component 13.

[0071] Wherein, the first vibration source includes a floating outer plate 121, and there is a sliding limit in the x direction between the floating outer plate 121 and the mounting frame 11;

[0072] The second vibration source includes a floating inner plate 122, and a sliding limit in the y direction is provided between the floating inner plate 122 and the floating outer plate 121;

[0073] The first vibration source and the second vibration source are driven by a motor 124. An eccentric wheel 123 is fixed to the output shaft of the motor 124. The floating inner plate 122 is fixed to the eccentric wheel 123. The floating outer plate 121 is fixedly connected to the clamping structure. The motor 124 is fixed to the mounting frame 11.

[0074] The sliding limiter is a cross roller guide rail 125.

[0075] The vibration component 12 is used to maintain a small reciprocating motion in the x direction and a small reciprocating motion in the y direction when the box body picking component 13 installs the box body part of the junction box on the bus bar, so that the box body picking component 13 vibrates continuously, making it easier for the bus bar to pass through the bus bar through-hole 101 of the box body part of the junction box, further improving the installation efficiency of the junction box, and avoiding direct rigid connection between the bus bar and the through-hole, thereby ensuring the installation quality of the junction box.

[0076] In other embodiments, the horizontal vibration may also include vibration in the x or y direction, and the vibration source includes a first vibration source that provides horizontal vibration in the y direction for the box body picking component 13 or a second vibration source (not shown in the figure) that provides horizontal vibration in the x direction for the box body picking component 13.

[0077] Among them, the first vibration source or the second vibration source includes a floating plate, which is fixedly connected to the clamping structure, and has a sliding limit in the x or y direction between the floating plate and the mounting frame 11; the floating plate can be driven, for example, by a linear vibrator, to provide horizontal vibration in the x or y direction for the box body picking component 13.

[0078] This solution only provides vibration in the x or y direction and can be used in conjunction with one or two pairs of clamping structures. It is suitable for situations where the resistance to single horizontal penetration is large and rapid penetration is difficult when the busbar is penetrated 101 .

[0079] In addition, when used with a pair of clamping structures, the y-direction vibration can be used with a pair of clamping structures in the x-direction, and the x-direction vibration can be used with a pair of clamping structures in the y-direction; this design is suitable for situations where the single horizontal direction positioning of the junction box is not accurate and it is easy to quickly punch a hole.

[0080] like Figure 2 and Figure 4 As shown, the box body picking assembly 13 also includes a pair of expansion blocks 135, which are distributed side by side with the two bus bars. When the two bus bars pass through the bus bar through-holes 101 on the junction box picked up by the clamping structure, the two expansion blocks 135 are located between the two bus bars; the pair of expansion blocks 135 are driven to push apart and bend the two bus bars.

[0081] The pair of expansion blocks 135 are connected to the pair of clamping structures via waist-shaped holes. The pair of expansion blocks 135 are relatively fixed to the pair of clamping structures on the same side of the pair of expansion blocks 135 and the clamping structures, and the two share a common drive, which is a linear drive.

[0082] In this embodiment, the pair of expansion blocks 135 are fixedly connected via the connecting plate and the second cylinder 132 , and the second cylinder 132 is commonly used to drive the pair of expansion blocks 135 and the pair of return blocks 134 .

[0083] The box body picking component 13 also includes a second adjustment structure for adjusting the relative positions of the pair of expansion blocks 135. The second adjustment structure is a waist-shaped hole on the connecting plate for fixing the expansion block 135. Through the waist-shaped hole, the relative positions of the two expansion blocks 135 can be adaptively adjusted according to the position of the junction box.

[0084] After the two pairs of clamping structures limit the four end faces of the box body of the junction box, that is, after the box body picking assembly 13 picks up the junction box, the bending parts of the two expansion blocks 135 are located between the two bus bar through-holes 101. When the box body picking mechanism 1 is driven to drive the two bus bar through-holes 101 of the junction box to correspond to the two bus bars and perform through-holes, the pair of expansion blocks 135 are located between the two bus bars. At this time, the first cylinder 131 and the second cylinder 132 drive the two pairs of clamping structures to loosen the junction box. At the same time, the second cylinder 132 will drive the two expansion blocks 135 to push the bus bars passed through the junction box to both sides, so that the bus bars are bent, which is convenient for subsequent welding between the bus bars and the junction box. The structure is compact and the design is ingenious.

[0085] like Figure 1-2 and Figure 4 As shown, the expansion mechanism 2 includes an insert block 21, the two plug-in ends of the insert block 21 correspond one-to-one with the two busbar through-holes 101 on the junction box, and the insert block 21 is connected to the mounting frame 11 via a connecting frame; the middle of the plug-in end matches the standard busbar through-hole 101, and the tail of the plug-in end gradually retracts from top to bottom to facilitate insertion into the busbar through-hole 101 for expansion.

[0086] Before the clamping structure clamps the junction box, the expansion mechanism 2 can be used to expand or correct the position of the busbar through-hole 101 that does not meet the standard, thereby facilitating the subsequent insertion of the busbar into the junction box and further improving the installation efficiency of the junction box.

[0087] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
