Description

Technical Field

[0001] This utility model relates to the field of busbar testing technology, specifically to a busbar strength stress testing device. Background Technology

[0002] Diamond wire, a key consumable in the photovoltaic silicon dicing field, directly impacts silicon wafer processing quality and production costs. This material is produced by electroplating, where diamond micropowder is uniformly bonded to the surface of a high-strength metal busbar (typically a copper or aluminum alloy substrate), forming a composite wire with excellent cutting performance. In the technological evolution of cost reduction and efficiency improvement in the photovoltaic industry, the bending performance of diamond wire has become a core indicator for evaluating its overall quality—good bending flexibility significantly reduces the risk of wire breakage during dicing, extends wire lifespan, and thus improves the slicing yield and wafer output of monocrystalline silicon rods.

[0003] Traditional bending performance testing devices employ a single-end fixed structure, using a drive mechanism to cause the movable end to reciprocate in a plane, forcing the wire to undergo periodic bending deformation within a preset plane. This testing mode has three major technical limitations: First, it can only simulate unidirectional bending conditions and cannot reproduce the complex bending state in three-dimensional space during actual cutting; second, the testing process does not introduce tensile stress loads, resulting in a significant difference from the actual stress situation under wire tension; third, the bending trajectory of the fixed plane is difficult to reflect the impact of multi-directional alternating loads on the fatigue life of the wire. In view of these issues, in-depth research was conducted, leading to this case. Utility Model Content

The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Example

[0022] like Figure 1-4 As shown, the fixed processing structure includes: two pairs of horizontal telescopic blocks 2, multiple horizontal sleeve springs 3, multiple horizontal telescopic limiting shafts 4, two pairs of adsorption electromagnets 5, two pairs of adsorption magnets 6, one pair of collecting rollers 7, two pairs of collecting discs 8, four pairs of convex lifting blocks 9, two pairs of arc extrusion blocks, multiple lifting limiting shafts 10, two pairs of circular metal plates, two pairs of extrusion electromagnets, eight pairs of adsorption conductive arc plates, and four pairs of extrusion circular magnets 11;

[0023] Specifically, the detection bracket 1 has two pairs of horizontal telescopic slots, two pairs of horizontal telescopic blocks 2 are respectively movably inserted into the inner side of the two pairs of horizontal telescopic slots, multiple horizontal telescopic limiting shafts 4 are respectively inserted into the inner side of the two pairs of horizontal telescopic slots, and multiple horizontal telescopic limiting shafts 4 are respectively movably inserted into the two pairs of horizontal telescopic blocks 2, two pairs of adsorption electromagnets 5 are respectively installed on the two pairs of horizontal telescopic slots, two pairs of adsorption magnets 6 are respectively installed on the two pairs of horizontal telescopic blocks 2, multiple horizontal sleeve springs 3 are respectively sleeved on multiple horizontal sleeve springs 3, a pair of collecting rollers 7 are respectively installed on the two pairs of horizontal telescopic blocks 2, and two pairs of collecting discs 8 are respectively installed on a pair of horizontal telescopic blocks 2.

[0024] It should be noted that, as described above, by fixing the busbar to a pair of collecting rollers 7 inside the detection bracket 1, the extrusion electromagnet on the collecting roller 7 is energized, and the magnetism of the extrusion electromagnet is transmitted to the circular metal sheet. The magnetism of the circular metal sheet is transmitted to eight pairs of adsorption and conduction arc plates, which in turn adsorb and conduction arc plates to the extrusion extrusion ring magnet 11. The extrusion extrusion ring magnet 11 drives the convex lifting block 9 on it, causing the convex lifting block 9 to move stably up and down along multiple lifting limit axes 10. The four pairs of convex lifting blocks 9 drive the arc extrusion blocks on them to move relatively in and out, thereby stably raising and lowering the two pairs of arc extrusion blocks along the lifting extrusion groove on the collecting disc 8, thus extruding the two pairs of arc extrusion blocks. The pressure block is tightly pressed onto the collecting roller 7, thereby fixing the busbar to the arc-shaped pressure block, thus rotating and tightly pressing the busbar. At the same time, the busbar is pressed through the stretching and bending structure, so that the pair of collecting rollers 7 can stably extend and retract horizontally along the two pairs of horizontal telescopic blocks 2, thereby stably extending and retracting the two pairs of horizontal telescopic blocks 2 along multiple horizontal telescopic limit shafts 4. The horizontal telescopic blocks 2 drive the horizontal sleeve springs 3 on them to compress and extend, thereby performing horizontal stretching and buffering. At the same time, the electromagnet 5 can be energized to magnetically attract the magnet 6, and the magnet 6 drives the horizontal telescopic blocks 2 on it, thereby magnetically attracting and tightening the horizontal telescopic blocks 2.

The two pairs of repulsion metal blocks 20 are installed in a cross shape inside the rotating extrusion annular tube 13. The two pairs of repulsion electromagnets 21 are respectively installed on the two pairs of repulsion metal blocks 20. The multiple extrusion magnets 22 are respectively installed on the multiple extrusion telescopic convex blocks 18. The multiple concave extrusion bearing blocks 23 are respectively installed on the multiple extrusion telescopic convex blocks 18. The multiple extrusion concave wheels 24 are respectively installed on the multiple concave extrusion bearing blocks 23.

[0027] It should be noted that, as described above, the rotary drive 15 operates, driving the rotary gear 16 on its drive end to rotate. The rotary gear 16 then drives the rotary extrusion annular tube 13, causing it to rotate stably along a pair of annular supports 12. The rotary extrusion annular tube 13, in turn, drives the four pairs of eye-shaped extrusion supports 17 to rotate stably and vertically. Two pairs of repulsion electromagnets 21 are energized, magnetically conducting magnetic transmission to two pairs of repulsion metal blocks 20. The repulsion metal blocks 20 then conduct magnetic transmission to multiple... Multiple extrusion magnets 22 repel each other magnetically, and the multiple extrusion magnets 22 drive the extrusion telescopic protrusion blocks 18 on them respectively, so that the extrusion telescopic protrusion blocks 18 can stably extend and retract along multiple lifting limit shafts 19. The multiple extrusion telescopic protrusion blocks 18 drive the concave extrusion bearing blocks 23 on them respectively, and the multiple concave extrusion bearing blocks 23 drive the extrusion concave wheels 24 on them respectively. The multiple extrusion concave wheels 24 perform cross-shaped extrusion on the busbar, and then rotate to extrude and stretch the busbar, thereby performing multi-angle lifting, extrusion and stretching.
