Description

Technical Field

[0001] The invention belongs to the field of electrodeposition equipment, and in particular relates to a roller of a diamond wire electrodeposition equipment. Background Art

[0002] New energy has become one of the current and even future long-term development themes. With the high attention paid to energy security and environmental protection issues at home and abroad, solar energy is an inexhaustible new energy. Photovoltaic technology uses solar energy to generate electricity for thousands of households and has developed rapidly in recent years.

[0003] The rapid development of photovoltaics is inseparable from the breakthrough and development of its supporting equipment technology. Diamond wire saw tools represented by diamond wire have been widely used in the cutting and slicing of silicon crystals, and their market demand is increasing day by day.

[0004] In order to improve production efficiency, rollers are added at both ends of the electrodeposition tank. Multiple diamond wires are wound in parallel on the rollers at both ends to form a wire net. The entire wire net is the cathode and immersed in the electrodeposition liquid. The shaft ends at both ends of the rollers are connected to the cathode of the power supply to conduct electricity to the rollers. The titanium basket of the electrodeposition liquid is the anode. When the power is turned on to form a circuit, the rollers rotate at a constant speed, driving the wire net to pass through the electrodeposition liquid. The electrodeposition liquid contains diamonds, and finally the diamonds are wrapped on the surface of the wire matrix through electrodeposition to form diamond wires.

[0005] The existing roller structure is a squirrel cage structure. The middle shaft is the support shaft and conductor, the multi-slot partition is a non-metallic body, and the wire is in contact with a number of metal round rods, which achieves a small contact area. However, the wire body jumps during the rotation of the roller, resulting in poor contact between the wire and the rod, which is prone to electric sparks, slot jumping and line paralleling, thereby causing product defects and wire breaks. Summary of the invention

[0006] The present invention provides a roller for diamond wire electrodeposition equipment, which aims to solve the shortcomings of the prior art and provide a roller for diamond wire electrodeposition with simple structure, high matching accuracy, stable wire network during operation and no electric sparking during the process.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] A roller for a diamond wire electrodeposition device, characterized in that:

[0009] The outer wall of the inner cylinder core of the metal cylinder is provided with an axial boss, the upper surface of each boss is an arc surface, and the arc surface of the upper surface of each boss is a part of a cylindrical surface coaxial with the inner cylinder core;

[0010] The outer wall of the outer sleeve of the metal cylindrical body is provided with an annular groove, and the bottom surface of the annular groove is provided with a through hole;

[0011] The outer ring is arranged outside the inner cylinder core to form a roller;

[0012] The inner cylinder core is fixedly connected to a metal shaft, and the shaft is mounted on bearings of shaft seats on both sides.

[0013] The axial bosses are evenly distributed around the circumference.

[0014] The spacing between adjacent annular grooves is the same.

[0015] The through holes are evenly distributed around the circumference.

[0016] The inner wall of the outer ring is provided with axial bosses which are evenly distributed around the circumference.

[0017] The inner cylinder core is connected to the shaft through a key structure.

[0018] Both ends of the shaft are machined with threaded holes for connecting conductive slip rings. Beneficial Effects

[0019] Compared with the prior art, the diamond wire running track on the roller of the present invention is no longer a polygon, but a circle; the relative jumping problem of the diamond wire and the roller is solved. In the present invention, the outer wall of the inner cylinder core is a gear shape, so the contact contour of the diamond wire is a contour circle, but it is not a complete circle, which ensures good contact and realizes the principle of small contact area. Since the contact contour is a circle, it also avoids the problem of excessive local current and wire jumping during the running process caused by the commonly used rod contact. The overall base of the present invention is a metal body with excellent conductivity, which can effectively avoid the phenomenon of nickel nodules growing between the plastic teeth on the existing roller, thereby avoiding wire breakage during the production process. The multi-groove metal outer ring is processed and formed in one time, and has high matching precision with the gear-shaped inner cylinder core. After installation and adjustment, there is no need for repeated adjustment, which improves the equipment utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0027] like Figure 3 As shown:

[0028] The outer wall of the inner cylinder core 3 made of metal material is provided with axial bosses 31 evenly distributed around the circumference. The upper surface of each boss 31 is an arc surface, and the arc surface of the upper surface of each boss 31 is a part of a cylindrical surface coaxial with the inner cylinder core 3. The boss 31 is used to support the diamond wire and supply power to the diamond wire.

[0029] like Figure 4 As shown:

[0030] The outer wall of the outer ring 4 of the metal cylinder is provided with annular grooves 41, and the spacing between adjacent annular grooves 41 is the same. The bottom surface of the annular groove 41 is evenly distributed with through holes 42, and the inner wall of the outer ring 4 is provided with axial bosses 43 evenly distributed around the circumference.

[0031] When the outer ring 4 is in threading operation, the diamond wire is accommodated in the annular groove 41, which can guide the diamond wire to avoid tangling.

[0032] like Figure 2 As shown:

[0033] A pair of shaft seats 2 are installed above the support frame 1, and the entire roller structure is fixed on the shaft seats 2. The shaft seats 2 and the frame 1 are connected by bolts;

[0034] The roller structure mainly includes an outer ring 4, an inner roller core 3, a sleeve 5 and a shaft 6.

[0035] The outer ring 4 is sleeved outside the inner cylinder core 3 to form a roller 1.

[0036] In order to transmit torque and ensure that there is no relative sliding between the roller 1 and the shaft 6, the inner cylinder core 3 is fixedly connected to the metal shaft 6 through a key structure. Threaded holes are processed at both ends of the shaft 6, and the threaded holes are used to connect the conductive slip ring.

[0037] One end of the sleeve 5 at both ends of the roller 1 contacts the outer ring of the bearing 24, and the other end contacts the inner rib plate of the inner cylinder core 3;

[0038] The shaft 6 and the roller 1 are integrally mounted on the shaft seat 2; the upper end of the shaft seat 2 is composed of upper and lower bearing bushes 25 that are interlocked and fixedly connected.

[0039] The bearing 24, inner end cover 23, outer end cover 28 and sealing ring 22 are installed in the bearing shell 25; the inner end cover 23 and the outer end cover 28 are fixed to the shaft seat 2 with bolts 21 and bolts 26, so that the bearing 24 is fixed in the bearing shell 25, and the sealing ring 22 is sleeved outside the shaft 6 and pressed against the bearing 24 to play a sealing role.

[0040] The shaft 6 passes through the bearing 24, the inner end cover 23, the outer end cover 28, and the sealing ring 22, so that the roller 1 is mounted on the two bearings 24 in the two shaft seats 2.

[0041] The tightening nut 27 has threads therein and is connected to the shaft 6 through the threads, and is tightened to fix the roller structure.

[0042] like Figure 1 As shown:

[0043] The present invention is actually applied and installed, and a support frame 1, an axle seat 2, a roller I and a diamond wire net II wound on the roller I are installed on both sides of the middle tank body III.

[0044] Multiple diamond wires are wound in parallel on rollers I at both ends to form a diamond wire mesh II. The entire diamond wire mesh II is the cathode and immersed in the electroplating liquid. The shaft ends at both ends of the shaft 6 connected to the roller I are connected to the power cathode of the conductive slip ring to conduct electricity to the roller I composed of the inner cylinder core 3 and the outer ring 4 made of metal. The titanium basket of the electroplating liquid is the anode. When the power is turned on to form a loop, the roller I rotates at a constant speed, driving the diamond wire mesh II to pass through the electroplating liquid in the middle tank III. The electroplating liquid contains diamonds, and finally the diamonds are wrapped on the surface of the wire matrix through electrodeposition to form diamond wires.

[0045] The diamond wire is accommodated in the annular groove 41 of the outer ring 4, which can guide the diamond wire to avoid tangling.

[0046] The diamond wire passes through the through hole 42 at the bottom of the annular groove 41 and contacts the upper surface of the axial boss 31. Since the arc surface of the upper surface of the boss 31 is a part of the cylindrical surface coaxial with the inner cylinder core 3, the contact profile of the diamond wire is a contour circle, but not a complete circle, which ensures good contact and realizes the principle of small contact area. Since the contact profile is a circle, the problem of excessive local current caused by the commonly used rod contact is also avoided.
