Description

Technical Field

[0001] This utility model relates to the field of high carbon steel busbar production technology, specifically a tension adjustment device for high carbon steel busbar production. Background Technology

[0002] Diamond wire, as the core material of diamond cutting wire, is mainly made of two material systems: high-carbon steel wire and tungsten wire. This material possesses excellent tensile strength (typical value > 3.5 GPa) and long fatigue life (cycle count > 10^6), making it particularly suitable for the demanding working conditions of silicon wafer cutting in the photovoltaic industry. In the precision machining process, two core processes—straightening and deformation forming—effectively eliminate residual stress inside the wire, improving cutting stability.

[0003] However, existing stress relief equipment suffers from significant technical bottlenecks: traditional devices rely solely on straightening or deformation processes, achieving a stress relief rate of less than 65%; furthermore, they lack modular adjustment mechanisms, making it difficult to adapt to the differentiated stress distribution characteristics of diamond wires with different specifications ranging from φ0.12 to 0.25 mm. These limitations result in incomplete residual stress removal, directly impacting the consistency of the cut surface quality and becoming a major technical bottleneck restricting the mass production of high-efficiency photovoltaic silicon wafers. Therefore, this case study was developed to address these issues in depth. Utility Model Content

[0020] Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. 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. Example

[0022] like Figure 1-3 As shown, the processing support 2 is mounted on the processing table 1, and the tension adjustment structure is mounted on the processing table 1 and the processing support 2. The tension adjustment structure includes: a pair of extrusion components, a striking component, and a rotary extrusion component.

[0023] Specifically, a pair of extrusion components are mounted on the processing bracket 2, and the pair of extrusion components are located on both sides of the processing table 1. The rotary extrusion component and the striking component are mounted on the processing table 1 and the processing bracket 2.

[0024] Specifically, the rotary extrusion assembly includes: a coin-shaped cylindrical tube 3, a pair of bushing bearings 4, a rotary drive motor 5, a rotary gear 6, a rotary bushing ring rack 7, multiple concave bearing blocks 8, multiple rotary extrusion wheels 9, multiple rotary rings 10, multiple rotary arc blocks 11, and multiple angle adjustment magnets 12.

[0025] Specifically, a pair of the aforementioned bearing sets 4 are mounted on the processing table 1 and the processing bracket 2. The coin-shaped cylindrical tube 3 is inserted into the inner side of the pair of bearing sets 4. The rotary drive motor 5 is mounted on the processing bracket 2. The rotary gear 6 is mounted on the drive end of the rotary drive motor 5. The rotary ring rack 7 is fitted onto the outer side of the coin-shaped cylindrical tube 3. The coin-shaped cylindrical tube 3 has multiple rotary ring 10 grooves, and each of the multiple rotary ring 10 grooves has an arc-shaped limiting groove. 10 are respectively inserted into the inner side of the grooves of the multiple rotating rings 10 via bearings; multiple rotating arc blocks 11 are respectively installed on the multiple rotating rings 10; and multiple rotating arc blocks 11 are respectively movably inserted into the inner side of the multiple arc limiting grooves; multiple angle adjusting magnets 12 are respectively installed on the inner side of the multiple rotating arc blocks 11 and the multiple arc limiting grooves; multiple concave bearing blocks 8 are respectively installed on the multiple rotating rings 10; and multiple rotating extrusion wheels 9 are respectively installed on the multiple concave bearing blocks 8.

[0026] It should be noted that, as described above, the operation of the rotary drive motor 5 drives the rotary gear 6 on the drive end of the rotary drive motor 5 to rotate. The rotary gear 6 drives the rotary ring rack 7 meshing with it to rotate. The rotary ring rack 7 drives the copper coin-shaped cylindrical tube 3 on it to rotate stably vertically. The copper coin-shaped cylindrical tube 3 rotates stably along a pair of set bearings 4 on the processing table 1 and processing support 2. The copper coin-shaped cylindrical tube 3 drives multiple concave bearing blocks 8 on its inner side. The multiple concave bearing blocks 8 drive the rotary extrusion rollers 9 on them respectively. The vertical rotation of the multiple rotary extrusion rollers 9 provides rotational buffering for the busbar. At the same time, the pair of angle-adjusting magnets 12 repel each other. The angle-adjusting magnets 12 drive the rotary arc block 11 on them, so that the rotary arc block 11 rotates stably along the inner side of the arc-shaped limiting groove. The rotary arc block 11 drives the rotary ring 10 on it. The rotary ring 10 drives the concave bearing blocks 8 on it, thereby changing the angle of the rotary extrusion rollers 9, thus extruding and stretching the busbar.

[0027] like Figure 1-3 As shown, the striking assembly includes: multiple spiral lifting blocks 13, multiple convex lifting telescopic blocks 14, multiple telescopic limiting shafts 15, multiple telescopic sleeve springs 16, multiple adsorption magnets 17, multiple conductive metal blocks 18, multiple L-shaped metal rods 19, multiple metal balls 20, metal conductive plates 21, and conductive electromagnets 22.

[0028] Specifically, multiple spiral lifting blocks 13 are installed parallel to each other on the inner side of the coin-shaped cylindrical tube 3; multiple convex lifting telescopic blocks 14 are movably inserted into pairs of telescopic spiral lifting blocks 13; multiple telescopic limiting shafts 15 are movably inserted into multiple spiral lifting blocks 13 and multiple convex lifting telescopic blocks 14; multiple telescopic sleeve springs 16 are respectively sleeved on multiple telescopic limiting shafts 15; multiple adsorption magnets 17 are respectively installed on multiple convex lifting telescopic blocks 14; multiple conductive metal blocks 18 are evenly inserted into the coin-shaped cylindrical tube 3; multiple L-shaped metal rods 19 are evenly installed on the processing bracket 2; multiple metal balls 20 are movably inserted into multiple L-shaped metal rods 19; the metal conductive plate 21 is connected to multiple L-shaped metal rods 19; and the conductive battery cabinet is installed on the metal conductive plate 21.

[0029] It should be noted that, as described above, the magnetic conduction of the metal conduction plate 21 is achieved through the conduction electromagnet 22, and the magnetic field of the multiple L-shaped metal rods 19 is transferred to the multiple metal balls 20 through the metal conduction plate 21. The magnetic field of the multiple metal balls 20 is transferred to the conduction metal block 18. The magnetic field of the conduction metal block 18 magnetically repels the adsorption magnet 17. The adsorption magnet 17 drives the convex lifting telescopic block on it, so that the convex lifting telescopic block moves stably along the telescopic limit axis 15 inside the pair of loop-shaped lifting blocks 13. Thus, during rotation observation, when the metal balls 20 come into contact with the conduction metal block 18, the convex lifting telescopic block is magnetically adsorbed. The telescopic sleeve spring 16 compresses and extends the convex lifting telescopic block, and the pair of telescopic sleeve springs 16 elastically push the convex lifting telescopic block, thereby elastically striking the busbar and relieving the stress on the busbar.

[0030] like Figure 1-3 As shown, the extrusion assembly includes: multiple lifting bearing blocks, multiple lifting extrusion concave wheels, multiple buffer spring columns, two pairs of lifting extrusion electromagnets, two pairs of toothed metal conduction blocks, and multiple conduction magnets;

[0031] Specifically, the processing bracket 2 has multiple lifting extrusion bearing slots, multiple lifting bearing blocks are movably inserted into the inner side of the multiple lifting extrusion bearing slots, multiple lifting extrusion concave wheels are respectively installed on the multiple lifting bearing blocks, multiple buffer spring columns are respectively installed on the inner side of the multiple lifting extrusion bearing slots and connected to the multiple lifting bearing blocks, two pairs of toothed extrusion conduction blocks are respectively connected to the upper and lower ends of the multiple lifting extrusion bearing slots, two pairs of lifting extrusion electromagnets are respectively installed on two pairs of toothed metal conduction blocks, and multiple conduction magnets are respectively installed on the multiple lifting bearing blocks;

[0032] It should be noted that, in the above process, the toothed metal conduction block is magnetically conducted by the lifting and pressing electromagnet, and the toothed metal conduction block magnetically repels multiple conducting magnets. The multiple conducting magnets drive the lifting bearing blocks on them, so that the multiple lifting bearing blocks move stably up and down along the inner side of multiple lifting and pressing bearing grooves. The lifting bearing blocks drive the lifting and pressing concave wheels on them, and the multiple lifting and pressing concave wheels perform vertical lifting and pressing buffering on the busbar. At the same time, the buffer spring column provides buffering.

[0033] As a preferred option, the processing support 2 is further equipped with a tension sensor.

[0034] As a preferred option, the processing support 2 is further provided with a cooler assembly.

[0035] As a preferred embodiment, the processing support 2 is further provided with a cooling fan assembly.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
