Description

Technical Field

[0001] The present invention belongs to the technical field of diamond busbar processing, and specifically refers to a guiding and conveying device for diamond busbar wire. Background Art

[0002] The diamond busbar is a raw material wire for making diamond wire. It is usually made of high-strength and high-wear-resistant metal (such as high-strength steel or other alloy materials). After special process treatment, diamond micropowder particles are uniformly consolidated on the surface of the diamond busbar to form diamond wire. Due to its unique structure, this diamond wire has excellent cutting performance and durability, and is widely used in the cutting processing of hard and brittle materials, such as silicon wafer cutting, stone cutting, etc. In the processing technology of diamond busbar, it is inevitable to use guide wheels to guide and convey the wire. The main function of the guide wheel is to guide the wire (such as copper wire, steel wire, etc.) to run stably. Through precise positioning and guiding, it is ensured that the wire will not deviate from the predetermined path during the running process.

[0003] At present, the conveying of the wire includes single-wire conveying or multi-wire conveying in a group. The multi-wire conveying is the same as the single-wire conveying, and both are conveyed by an integral rotating roller. Multiple grooves are provided on the roller surface for the wire to prevent the wire from shifting. However, the integral rotating roller has the same supporting effect on each wire. When the tension of one of the wires fluctuates while the other wires have no tension fluctuation, the rotating roller cannot provide effective support for the wire with the fluctuating tension in time, which may cause the wire to have an increased fluctuation amplitude, break away from the roller or break. Therefore, there is an urgent need for a guiding and conveying device that can adapt to single-wire or multi-wire guiding at the same time and can provide stable support for each single wire.

[0019] The accompanying drawings are used to provide a further understanding of the embodiments and form a part of the specification. They are used in conjunction with the embodiments to explain, but do not constitute a limitation to the embodiments. Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments without creative efforts belong to the scope of protection.

[0021] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the embodiments.

[0022] During the process of guiding and conveying a bundle of diamond busbar filaments by an integral guide roller, when the tension of some of the filaments becomes unstable, the guide roller cannot intervene in the tension of the filaments in time, resulting in the filaments with tension fluctuations affecting the conveyance of other filaments. Therefore, the embodiments of the present invention provide a guiding and conveying device for diamond busbar filaments, aiming to solve the problem that the tension of individual filaments cannot be adjusted when multiple filaments are conveyed simultaneously.

[0023] As Figure 1 shown, the device mainly includes a plurality of guide wheels 001 arranged along the axial direction. Each guide wheel 001 is used to convey a single filament. After the plurality of guide wheels 001 are rotatably connected to each other, a guide wheel group (guide roller) capable of conveying multiple filaments is formed. Adjacent two guide wheels 001 are rotatably connected in sequence along the axial direction. The guide wheels 001 are rotatably installed on the surface wall of the device through shafts. The device herein includes but is not limited to drawing, cleaning, drying equipment, etc. The guide wheels 001 are used in the device for guiding and conveying filaments.

[0024] As Figure 2 and Figure 3 shown, the guide wheel 001 includes a guide wheel shaft 10 and a guide wheel ring 20 installed outside the guide wheel shaft 10. A guide groove 200 for accommodating the filament is provided on the outer surface of the guide wheel ring 20. When the guide wheel ring 20 rotates, the filament is guided and conveyed through the guide groove 200, and each guide groove 200 accommodates a single filament.

[0025] During the process of wire material conveying by a general guide wheel 001, the rotation of the guide wheel 001 includes an active mode and a passive mode. In the active mode, the guide wheel 001 is driven by a motor to rotate, which can more precisely control the wire drawing speed and tension, reduce the friction and wear of the wire, but the cost is relatively high. For the guide wheel 001 rotating in the passive mode, the cost is relatively lower, but its rotation speed is driven by the wire pulling, so its controllability of the wire is poor, and the friction and wear are also large.

[0026] In order to improve the controllability of the guide wheel 001 rotating in the passive mode for the wire, a support bladder ring 30 is fixedly arranged between the guide wheel ring 20 and the guide wheel shaft 10. The support bladder ring 30 is connected to an external pressure regulating device. The pressure regulating device can input / output pressure medium into the support bladder ring 30 and is used to adjust the volume of the pressure medium in the support bladder ring 30, so as to change the distance between the guide wheel ring 20 and the guide wheel shaft 10 according to the pressure change between the wire and the guide wheel ring 20.

[0027] In this way, when the pressure of the wire on the guide wheel ring 20 increases, the pressure of the guide wheel ring 20 on the support bladder ring 30 also increases. At this time, the pressure regulating device is used to partially extract the pressure medium in the support bladder ring 30, so that the contact part between the guide wheel ring 20 and the wire moves towards the axis, reducing the supporting force of the support bladder ring 30 on the guide wheel ring 20 to lower the pressure between the guide wheel ring 20 and the wire. When the pressure of the wire on the guide wheel ring 20 decreases, the pressure of the guide wheel ring 20 on the support bladder ring 30 also decreases. At this time, the pressure regulating device is used to introduce pressure medium into the support bladder ring 30, so that the contact part between the guide wheel ring 20 and the wire moves towards the outer side away from the axis, increasing the supporting force of the support bladder ring 30 on the guide wheel ring 20 to increase the pressure between the guide wheel ring 20 and the wire, so as to maintain a set pressure between the guide wheel ring 20 and the wire and enhance the controllability of the guide wheel ring 20 for the wire without power input.

[0028] Furthermore, in order to detect the pressure change between the wire and the guide wheel ring 20 and control the content of the pressure medium in the support bladder ring 30 according to this pressure change.

[0029] In some embodiments, a pressure sensor 33 for detecting the internal pressure of the support bladder ring 30 is arranged in the support bladder ring 30. A first control valve 60 is arranged between the support bladder ring 30 and the pressure regulating device. Both the pressure sensor 33 and the first control valve 60 are electrically connected to the pressure regulating device. The first control valve 60 can adopt a two-way solenoid valve, and the first control valve 60 is configured to open when the detected value of the pressure sensor 33 fluctuates, and input or output pressure medium into the support bladder ring 30 through the pressure regulating device to maintain the internal pressure value of the support bladder ring 30.

[0030] Thus, according to the material characteristics of the wire (such as diameter, material, etc.), a suitable range of the pressure value between the wire and the guide wheel ring 20 is set, as well as the internal pressure range of the support bladder ring 30 under this range. When the internal pressure value of the support bladder ring 30 detected by the pressure sensor 33 exceeds the preset range, the first control valve 60 opens, and the pressure regulating device inputs or outputs pressure medium into the support bladder ring 30 to maintain the internal pressure value of the support bladder ring 30, so that the pressure between the wire and the guide wheel ring 20 is in a stable state.

[0031] As Figure 1 and Figure 4 shown, in order to ensure that the rotation process of the guide wheel shaft 10 does not affect the input or output of the pressure medium from the pressure regulating device into the support bladder ring 30, a shaft hole 100 is provided in the axial direction of the guide wheel shaft 10, and the first control valve 60 is arranged between the shaft hole 100 and the support bladder ring 30.

[0032] Furthermore, the guide wheel shaft 10 includes a shaft body 11 and a shaft sleeve 12. The shaft hole 100 is located at the center of the shaft body 11. A valve mounting hole for installing the first control valve 60 is provided on the outer side wall of the shaft body 11. The first control valve 60 is fixedly installed on the side surface of the shaft body 11. The first control valve 60 is communicated with the input / output port of the pressure regulating device through an inner conduit 61, and the diameter of the inner conduit 61 is smaller than the diameter of the shaft hole 100. Among them, the inner conduit 61 is constructed as a "T"-shaped tee structure. One end of the inner conduit 61 is communicated with the first control valve 60, and the other two ends are connected with the inner conduits 61 in the other adjacent guide wheel shafts 10 that are connected to each other.

[0033] In some embodiments, a shaft shoulder 111 is fixedly provided at one end of the shaft body 11, and a shaft groove 112 is provided at the other end. The shaft shoulders 111 and shaft grooves 112 on any two adjacent shaft bodies 11 can be inserted into each other and fixed by bearings, so that the two adjacent shaft bodies 11 are rotatably connected. And a sealing ring 611 is rotatably arranged at the end of the inner conduit 61. The sealing rings 611 can be inserted and fixed to each other. After being fixed, the inner conduits 61 can rotate relative to each other while being able to seal and convey the pressure medium. The pressure medium generally adopts liquid media such as water or oil. Thus, it is ensured that the rotation process of the guide wheel shaft 10 does not affect the input or output of the pressure medium from the pressure regulating device into the support bladder ring 30.

[0034] Furthermore, the shaft sleeve 12 is fixed on the outer side of the shaft body 11 in a key connection manner. A slot hole communicating with the first control valve 60 is provided on the shaft sleeve 12. A through hole nozzle 31 is provided on the fitting surface of the support bladder ring 30 and the shaft sleeve 12. The through hole nozzle 31 is communicated with the slot hole, so as to realize the first control valve 60 to control the communication between the inner conduit 61 and the inner cavity of the support bladder ring 30.

[0035] As Figure 5 、 Figure 6 and Figure 7As shown, the guide wheel ring 20 includes two ring seats 21, two half-ring seats 22 and two contact rings 23. The two ring seats 21 can be joined together along the axial direction of the guide wheel shaft 10 to form a first ring body with the ring portion outside the support bladder ring 30. The two half-ring seats 22 can be joined together along the radial direction of the guide wheel shaft 10 to form a second ring body with the ring portion outside the ring seat 21. The two contact rings 23 can be joined together along the radial direction of the guide wheel shaft 10 to form a third ring body with the ring portion outside the half-ring seat 22.

[0036] Among them, two limiting collar rings 50 are provided on both sides of the guide wheel ring 20 and are axially clamped outside the ring seat 21, half-ring seat 22 and contact ring 23, so that the half-ring seat 22 and the contact ring 23 are fixed on the ring seat 21.

[0037] In some embodiments, as Figure 6 shown, the cross-section of the ring seat 21 is set in an "L" shape. The ring seat 21 includes a first ring seat parallel to the axial direction and a second ring seat perpendicular to the axial direction. A collar slot 212 is provided at the outer edge of the second ring seat. A limiting ring groove 231 is provided at the outer edge of the contact ring 23. During installation, the two ring seats 21 are first axially moved closer to each other until they are in contact. At the same time, a protruding limiting arc bar 211 is provided on the outer wall of the first ring seat, and a limiting arc groove 223 is provided on the inner wall of the half-ring seat 22 corresponding to the limiting arc bar 211. Then, the two half-ring seats 22 are radially clamped outside the ring seat 21. When clamping, the limiting arc bar 211 and the limiting arc groove 223 are mutually engaged. After the half-ring seat 22 is clamped on the ring seat 21, the half-ring seat 22 and the ring seat 21 are locked and fixed to each other. Then, the two contact rings 23 are radially clamped into the assembly groove 221 on the half-ring seat 22. Finally, axially, the two ends of the limiting collar ring 50 are respectively clamped into the collar slot 212 and the limiting ring groove 231, and the outer wall of the half-ring seat 22 abuts against the inner wall of the limiting collar ring 50 to complete the assembly of the guide wheel ring 20.

[0038] Furthermore, after assembly, a flow guiding cavity 210 is formed axially between each ring seat 21 and the half-ring seat 22. The half-ring seat 22 is provided with a third flow guiding hole 222 communicating the two flow guiding cavities 210. A liquid supply hose 711 communicating with the flow guiding cavity 210 is fixedly provided on the side wall of the ring seat 21. The other end of the liquid supply hose 711 is communicated with an external liquid supply device, and a liquid medium can be input / output into the flow guiding cavity 210 through the liquid supply device.

[0039] In some embodiments, the liquid supply hose 711 can be provided in a pair. One of the liquid supply hoses 711 is used to supply liquid into the diversion cavity 210, and the other liquid supply hose 711 extracts liquid from the diversion cavity 210, enabling the liquid medium to circulate in and out of the diversion cavity 210, so that the liquid medium continuously flows into the diversion cavity 210 to exchange heat with the wheel ring seat 21, the half-ring seat 22, and the contact ring 23, thereby reducing the overall temperature of the guide wheel ring 20 during the guiding process.

[0040] Furthermore, the cross-section of the contact ring 23 is configured as an arc. A plurality of first diversion holes 230 are provided on both sides of the open end of the contact ring 23. The plurality of first diversion holes 230 are symmetrically distributed about the axis of the guide wheel shaft 10. Second diversion holes 220 are formed on the half-ring seat 22 corresponding to the first diversion holes 230. Both the second diversion holes 220 and the first diversion holes 230 are communicated with the diversion cavity 210, enabling the liquid medium in the diversion cavity 210 to flow onto the surface of the contact ring 23.

[0041] In some embodiments, the contact ring 23 can be made of a ceramic ring or a cemented carbide material, having good wear resistance. After the first diversion holes 230 and the second diversion holes 220 are respectively formed on the contact ring 23 and the half-ring seat 22, the liquid medium in the diversion cavity 210 can flow to the contact ring 23 and contact the wire. At this time, the liquid medium can be a lubricating liquid, which can not only cool the contact ring 23 and the wire, but also reduce the friction between the contact ring 23 and the wire, further reducing the wear of the wire and playing a protective role for the wire.

[0042] Wherein, one end of the liquid supply hose 711 is communicated with the diversion cavity 210, and the other end is communicated with the shaft hole 100. The shaft hole 100 is communicated with the liquid supply device. A second control valve 70 is provided at the connection between the liquid supply hose 711 and the shaft hole 100. A temperature sensor 24 is installed between the contact ring 23 and the half-ring seat 22. The second control valve 70 is configured to adjust the opening degree according to the temperature value detected by the temperature sensor 24, and the opening degree of the second control valve 70 is positively correlated with the temperature value detected by the temperature sensor 24.

[0043] In this way, the higher the temperature value detected by the temperature sensor 24, the larger the opening degree of the second control valve 70. At this time, the speed of the lubricating liquid conveyed by the liquid supply device into the diversion cavity 210 is faster. By increasing the industrial speed of the lubricating liquid, the purpose of rapid cooling is achieved, so as to reduce the friction of the contact ring 23 on the wire.

[0044] In some embodiments, a light-emitting sleeve 71 is sleeved outside the liquid supply hose 711. The light-emitting sleeve 71 is fixed on the outer wall of the shaft body 11. The light-emitting sleeve 71 is a hollow transparent tube body with an LED lamp. After being turned on, it is convenient to indicate the rotation state of the guide wheel 001, and it is convenient to observe and judge whether the guide wheel 001 rotates and the rotation speed, so as to judge whether the wire is normally conveyed.

[0045] As Figure 4 and Figure 6 shown, the outer side surface of the support bladder ring 30 fits against the inner side surface of the wheel ring seat 21, the inner side surface of the support bladder ring 30 fits against the outer wall of the sleeve 12, and two sets of connecting ring strips 32 are fixedly provided at both the inner and outer edges of the support bladder ring 30. The two sets of connecting ring strips 32 are respectively clamped and fixed to the outer side of the sleeve 12 and the inner side of the guide wheel ring 20 through the positioning rings 40.

[0046] Among them, ring strip slots 214 are formed at positions corresponding to the connecting ring strips 32 on the wheel ring seat 21, and corresponding slots are formed at positions corresponding to the connecting ring strips 32 on the sleeve 12. After the connecting ring strips 32 on the inner and outer sides of the support bladder ring 30 are respectively clamped into the corresponding slots, the positioning rings 40 are used for fixing. The positioning rings 40 include a first positioning ring 41 installed on the sleeve 12 and a second positioning ring 42 installed on the wheel ring seat 21. A positioning ring slot 213 is further provided on the wheel ring seat 21 corresponding to the second positioning ring 42. A stepped shape is formed between the ring strip slot 214 and the positioning ring slot 213. The first positioning ring 41 and the second positioning ring 42 are both installed and fixed by screws.

[0047] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0048] The above describes the implementation manner, and this description is not restrictive. What is shown in the drawings is only one of the implementation manners, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments without creative work without departing from the creative purpose, they shall fall within the scope of protection.
