Description

Technical Field

[0001] The utility model relates to the technical field of junction box fixing tooling, in particular to a photovoltaic component and an adjustable junction box gluing and fixing tooling. Background Art

[0002] One step in the photovoltaic module manufacturing process is installing a junction box on the laminated and cured modules. This involves using silicone to bond the junction box to the module's backsheet and to connect the module's conductive leads to the terminal blocks within the junction box. The silicone coating on the junction box must be uniform, with both the thickness and width meeting process requirements. If the coating is poor, the bonding strength between the junction box and the module backsheet will not meet these requirements, and the seal between the two will be poor. Insufficient bonding strength can cause the junction box to fall off during later use. Poor sealing can also allow rainwater or moisture from the air to enter the junction box during later use. The junction box's function is to channel the power generated by the module away, which can lead to a short circuit and, in severe cases, damage the junction box or the module. Therefore, evenly coating the junction box with silicone ensures a secure bond and a good seal with the backsheet, which is crucial for improving the production quality of photovoltaic modules.

[0003] Because the existing junction boxes are of various types and the designs of each manufacturer are different, when the junction box is replaced, the existing junction box gluing and fixing tooling cannot be compatible with the junction boxes produced by different manufacturers. The junction box gluing and fixing tooling needs to be replaced simultaneously. Frequent replacement of the junction box gluing and fixing tooling not only affects production efficiency, but also affects the gluing effect of the junction box.

[0004] Therefore, there is an urgent need for an adjustable and more versatile junction box gluing and fixing device to cope with changes in the junction box. Utility Model Content

The second positioning unit is provided with at least a pair of fixing hole groups. The second positioning unit is fixed to the positioning plate by a second fixing screw that passes through the fixing hole group and the second positioning hole group in sequence.

[0008] Furthermore, the first positioning block unit further includes two fixing blocks, the second positioning unit includes two second adjusting blocks, and the first adjusting block, the two fixing blocks and the two second adjusting blocks enclose and form a fixed space for fixing the junction box.

[0009] Furthermore, the two fixing blocks are fixed to the positioning plate as a whole, the first adjustment block is provided with a first clamping opening, the two fixing blocks constitute a second clamping opening, and the first clamping opening and the second clamping opening are arranged toward each other.

[0010] Furthermore, a pair of the first positioning hole groups includes two first positioning holes spaced apart along the X-axis direction, the first adjustment block is spaced apart and provided with two linear fixing holes, the two linear fixing holes constitute a pair of the linear fixing hole groups, and the size of the fixing space in the Y-axis direction is adjusted by adjusting the first fixing screw (connected to different linear fixing hole groups).

[0011] Furthermore, the two linear fixing holes of a pair of linear fixing hole groups are symmetrically arranged on both sides of the first clamping opening.

[0012] Furthermore, the length of the linear fixing hole is L1, and the distance between two adjacent pairs of the first positioning hole groups is L2, where L2 is less than L1.

[0015] Furthermore, the two fixing blocks are further formed with a channel, and the channel is communicated with the fixing space.

[0016] Furthermore, the first clamping opening and the second clamping opening are in an "eight" shape, a "V" shape or a "U" shape.

[0017] Compared with the prior art, the advantages of the present invention are:

A positioning block unit 21 and a pair of second positioning units 22 for fixing the junction box in the X-axis direction, the first positioning block unit 21 includes a first adjustment block 211, the first adjustment block 211 is provided with a pair of linear fixing hole groups, and the first adjustment block 211 is fixed to the positioning plate 1 by a first fixing screw 31 that passes through the linear fixing hole group and the first positioning hole group in sequence, the second positioning unit 22 is provided with at least a pair of fixing hole groups, and the second positioning unit 22 is fixed to the positioning plate 1 by a second fixing screw 32 that passes through the fixing hole group and the second positioning hole group in sequence.

[0032] When it is necessary to replace junction boxes of different sizes, the junction box is accurately positioned and fixed in the Y-axis and X-axis directions by adjusting the first positioning block unit 21 to match different first positioning hole groups and adjusting the second positioning unit to match different second positioning hole groups, thereby ensuring the accuracy and stability of the position of the junction box during the assembly process, and enabling the junction box gluing and fixing tooling to adapt to junction boxes of different sizes. Therefore, no matter how the size of the junction box changes, the safe fixation of the junction box can be ensured by adjusting the fixing position of the junction box fixing component, thereby improving the production efficiency of the photovoltaic module.

[0033] Furthermore, the first positioning block unit 21 further includes two fixing blocks 212 , and the second positioning unit 22 includes two second adjustment blocks 220 .

[0042] Furthermore, the two fixing blocks 212 are further formed with a channel 2121 , which is communicated with the fixing space and can be used for wiring.

[0043] Furthermore, the positioning plate 1 is provided with a glue overflow hole within a fixed space range, so that excess glue can flow out through the glue overflow hole.

[0044] Furthermore, the positioning plate 1 is provided with at least four mounting holes 11 on the four edges thereof, and the junction box gluing and fixing tool is fixed on the operating platform by means of bolts passing through the mounting holes 11 .
