TECHNICAL FIELD

[0001] The application relates to the technical field of photovoltaic junction box production, in particular to a pin welding strength detection clamp for a photovoltaic junction box diode. BACKGROUND

[0002] The diode is an important component of the photovoltaic junction box and plays an important role in protection, optimization and guarantee of stable operation of the system.

[0003] REFERENCE Figure 1 A diode assembly of a photovoltaic junction box comprises a diode 11 and two metal sheets 12, the two metal sheets 12 correspond to the pins of the diode 11 respectively, the pins of the diode 11 are welded and fixed on the metal sheets 12, and the two metal sheets 12 are arranged in parallel.

[0004] The welding strength between the pins of the diode 11 of the photovoltaic junction box and the metal sheets 12 is extremely important. If the welding strength is not ideal, such as virtual welding and weak welding, the photovoltaic junction box is prone to fail to operate normally. Therefore, after the diode 11 and the metal sheet 12 are welded, the detection personnel need to take tweezers to move the welding part of the pins of the diode 11 and the metal sheet 12, and observe and detect the welding strength of the pins of the diode 11 and the metal sheet 12. However, due to the small size of the diode 11 and the metal sheet 12, the detection personnel are not convenient for detecting the welding strength of the pins of the diode 11 and the metal sheet 12.

[0007] A pin welding strength detection clamp for a photovoltaic junction box diode comprises a clamp bottom plate, a clamping seat mounted on the clamp bottom plate, and a clamping block used for pressing the diode assembly on the clamping seat and slidably mounted on the clamp bottom plate.

Wherein, the fixture base plate 2 is a square metal plate, the sliding direction of the clamping seat 3 on the fixture base plate 2 and the sliding direction of the clamping block 4 on the fixture base plate 2 are parallel, and both are parallel to the width direction of the fixture base plate 2.

[0039] With reference to Figure 2 , the clamping seat 3 comprises two clamping parts 31 for placing diode assemblies and a connecting part 32 connecting the two clamping parts 31. Wherein, the two clamping parts 31 are arranged one by one corresponding to the two clamping blocks 4.

[0040] With reference to Figure 2 and Figure 3 , the connecting part 32 is provided with a sliding groove 321 on the bottom surface, and the sliding groove 321 is formed into a through groove structure through the front and rear surfaces of the connecting part 32.

Wherein, the locking boss 51 is arranged integrally with the fixture base plate 2. The top surface of the locking block 52 is provided with a locking counterbore 521 for arranging the locking bolt 53. In this embodiment, the locking assembly is provided with two locking bolts 53, and the two locking bolts 53 are arranged in parallel along the length direction of the locking block 52, so that the locking block 52 cannot rotate on the top surface of the locking boss 51. The top surface of the clamping seat 3 is also provided with a locking groove 322 for arranging the locking block 52.

[0042] In combination with Figure 2 and Figure 3 , the above-mentioned pin welding strength detection fixture of the photovoltaic junction box diode is arranged by setting the clamping seat 3 to slide on the fixture base plate 2 and the locking assembly, so that the position of the clamping seat 3 on the fixture base plate 2 can be adjusted according to the size of the diode assembly and the clamping seat 3 is locked, which helps to improve the universality of the pin welding strength detection fixture of the photovoltaic junction box diode.
