Description

Technical Field

[0001] The utility model relates to the technical field of diode assembly, in particular to an assembly jig for an R6C short-lead photovoltaic bypass diode. Background Art

[0002] At present, there are three common packages for photovoltaic bypass diodes, R-6, TO-263 and photovoltaic modules. These three package products are widely used in photovoltaic bypass. Each has its own advantages and disadvantages, but one common feature is that the bypass current is less than 30A. There are photovoltaic modules with more than 30A in the market, but they are not mature yet, the price is also very high, and the market application is limited. R-6 / TO-263 package products cannot meet the customer's heat dissipation requirements due to thermal resistance, and are currently only suitable for the market below 25A. Therefore, customers put forward the demand for R6C with lower cost.

[0003] During the manufacturing process of R6C diode, it is necessary to weld the core particle between two copper leads and then seal it with plastic packaging material. However, at present, when packaging the two copper leads and the core particle, the height of the assembly hole on the jig cannot be adjusted, resulting in the need to make multiple jigs when packaging R6C diodes of different heights, which increases the company's cost. Therefore, we proposed an R6C short-lead photovoltaic bypass diode assembly jig to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when packaging two copper leads and a core particle, the height of the assembly hole on the jig cannot be adjusted, resulting in the need to manufacture multiple jigs when packaging R6C diodes of different heights, which increases the cost of the enterprise, and the proposed R6C short-lead photovoltaic bypass diode assembly jig is to solve the problem that when packaging two copper leads and a core particle, the height of the assembly hole on the jig cannot be adjusted, resulting in the need to manufacture multiple jigs when packaging R6C diodes of different heights, which increases the cost of the enterprise.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The invention discloses an assembly fixture for an R6C short-lead photovoltaic bypass diode, comprising a substrate, wherein a plurality of assembly holes are provided on the upper surface of the substrate, the bottom of the assembly holes is a conical surface, a through hole is concentrically arranged at the bottom of the assembly holes, and a plurality of trumpet-shaped nests are arranged inside the assembly holes, and the package height of the diode is changed by changing the number of nests in the assembly holes.

[0007] As a preferred technical solution of the utility model, positioning holes are provided at both ends of the substrate, and positioning pins are provided in the positioning holes. During installation, the positioning pins cooperate with the positioning holes to facilitate preliminary positioning of the substrate.

[0008] As a preferred technical solution of the utility model, mounting holes are provided at the four corners of the substrate, and the mounting holes are countersunk holes to prevent the mounting screws from being exposed on the surface of the substrate.

[0009] As a preferred technical solution of the utility model, the number of nestings in each of the assembly holes is two to four, and the outer wall of the nesting fits with the inner wall of the assembly hole.

[0010] As a preferred technical solution of the utility model, the angle between the two sides of the bottom surface of the assembly hole is 120°.

[0011] As a preferred technical solution of the utility model,

[0012] The beneficial effects of the utility model are:

[0013] By adding multiple nests in the assembly holes, when R6C diodes of different heights need to be packaged, the number of nested installations can be controlled to ensure that the copper leads are at the appropriate packaging height, thereby avoiding the need to make multiple types of assembly jigs and reducing the company's production costs.

[0019] Reference Figure 1-3 The R6C short-lead photovoltaic bypass diode assembly fixture comprises a substrate 1, both ends of the substrate 1 are provided with positioning holes 3, and positioning pins are arranged in the positioning holes 3. During installation, the substrate 1 is initially positioned by the cooperation between the positioning pins and the positioning holes 3. Meanwhile, the four corners of the substrate 1 are provided with mounting holes 4, which are countersunk holes to prevent the mounting screws from being exposed on the surface of the substrate 1.

[0020] The upper surface of the substrate 1 is provided with a plurality of assembly holes 2, which are distributed in an array on the substrate 1. The bottom of the assembly hole 2 is a conical surface, and a through hole is concentrically arranged at the bottom of the assembly hole 2. The diameter of the assembly hole 2 is 6.9 mm, and the inner diameter of the through hole is 2.12 mm. The conical setting of the bottom allows the copper lead 6 to be automatically centered during assembly. Figure 2 As shown, the angle between the two sides of the bottom surface of the assembly hole 2 is 120°;

[0021] Among them, a plurality of trumpet-shaped nests 5 are arranged inside the assembly hole 2, and a through hole is arranged in the middle of the nest 5. The inner diameter of the through hole is the same as the inner diameter of the through hole at the bottom of the assembly hole 2. The packaging height of the diode is changed by changing the number of nests 5 in the assembly hole 2.

[0022] Secondly, the number of nests 5 in each of the assembly holes 2 is two to four, and the outer wall of the nest 5 fits with the inner wall of the assembly hole 2, and the height of each nest 5 is 2 mm.

[0023] In this embodiment: When using this fixture, Figure 2 As shown, different numbers of nests 5 are installed in the assembly hole 2, two copper leads 6 are arranged opposite to each other and a core particle 7 is welded in the middle thereof, so that a plastic encapsulation material can be added into the assembly hole to encapsulate the copper lead 6 and the core particle 7.
