Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic silicon wafer manufacturing, and in particular to a wire-breaking and wire-retrieving device. Background Art

[0002] Solar cell silicon wafers are cut from silicon blocks or silicon rods by a multi-wire saw. With the development trend of the silicon wafer industry, diamond wire multi-wire cutting technology has become the mainstream technology for multi-wire cutting. Diamond wire multi-wire cutting technology has the advantages of high cutting efficiency, small silicon wafer damage layer, and small silicon wafer TTV (Total Thickness Variation). Multi-wire cutting is to first wrap the diamond wire around the guide wheel groove of the guide wheel, thereby limiting the horizontal movement of the diamond wire and making its cutting position constant. Multiple diamond wires are wound in circles to form a wire mesh, and the silicon rod is installed on the workbench. The workbench feeds in the direction close to the diamond wire according to the set feed speed. At the same time, the diamond wire slicer adopts the method of unidirectional circulation or reciprocating circulation of the diamond wire to form a relative grinding motion between the diamond wire and the object to be cut, thereby achieving the purpose of silicon wafer cutting.

[0003] When the diamond wire is cutting, it may break during the process of cutting silicon rods due to wire jumpers, overlapping wires, foreign objects or defects in the diamond wire itself. In order to avoid the loss of silicon rods in the non-broken area after the wire break, the wire mesh will be cleaned, the broken wire will be welded and the cutting process will continue to reduce the loss of silicon rods. However, due to the welding machine and operability, a long loose steel wire will be left outside the wire mesh after welding. To continue cutting, this part of the steel wire must be put into the wire mesh to maintain a certain tension.

[0004] Since the slack wire is taken up into the wire net due to the tension difference caused by the movement of the steel wire during wire reeling, the existing wire reeling method is usually as follows: the operator uses a wire reeling device to complete the wire reeling operation. The wire reeling device consists of two parts: a pulley and a handle. When reeling in the wire, the operator holds the handle to guide the broken wire with the hand-held pulley and controls the steel wire to slowly reel in the wire net.

[0005] However, the existing wire-winding method requires the simultaneous completion of steel wire guidance, slow approach to the wire net, and control of the slicer. Multiple tasks are performed simultaneously, which is difficult to operate and requires high operating skills of the operator. The tension during wire winding is entirely controlled by the operator's hands, which poses a safety hazard and has a large error. The fluctuation of the wire net tension can easily cause secondary wire breakage or poor color difference on the surface of the cut silicon wafer. Summary of the invention

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] Example 1

[0040] This embodiment provides a broken wire collection device for collecting the broken wire 100 of the wire net of the cutting machine back into the wire net, see Figure 1 The wire-breaking and wire-taking device comprises a support rod 1, a sliding assembly 2 arranged on the support rod 1, a tensioning assembly 3 arranged on the sliding assembly 2, and a load assembly 4.

[0041] Specifically, the sliding assembly 2 includes a slide rail 21 and a slider 22. In order to ensure the stability and safety of the wire-breaking and wire-taking device when in use, stoppers 5 are provided at both ends of the slide rail 21, and the stoppers 5 limit the slider 22 from detaching from the slide rail 21 in the length direction of the slide rail 21.

[0042] In this embodiment, the stopper 5 is an L-shaped structure, and the stopper 5 is located in the slide groove 23 of the slide rail 21. The horizontal section (unnumbered) of the stopper 5 is installed on the bottom wall of the slide groove 23, and the vertical section (unnumbered) extends along the thickness direction of the slide rail 21 to contact the slider 22, thereby limiting the slider 22 from separating from the slide rail 21. Of course, in other embodiments, the stopper 5 can also be set to other structures, such as a stopper formed by two inner side walls protruding relatively from the slide groove 23, and the stopper can contact the slider 22 to limit the movement of the slider 22. The stopper can be of any shape, and this application does not make specific restrictions on this, and it can be adjusted according to design requirements.

[0043] The tensioning assembly 3 is used to tension the broken wire 100. The tensioning assembly 3 includes a first tensioning unit and a second tensioning unit. The first tensioning unit is arranged on the head end of the slide rail 21, and the second tensioning unit is arranged on the slider 22. The broken wire 100 is wound around the first tensioning unit and the second tensioning unit. It should be noted that the end where the first tensioning unit is located is the front end of the broken wire take-up device.

[0044] In this embodiment, the first tensioning unit includes two fixed pulleys 31 arranged at intervals in the height direction, and the second tensioning unit is a movable pulley 32 installed on the slider 22. In the height direction, the movable pulley 32 is located between the two fixed pulleys 31, and the movable pulley 32 is configured to be movable between the two fixed pulleys 31 along the length direction of the slide rail 21, and in the thickness direction of the slide rail 21, the centers of the two fixed pulleys 31 and the movable pulley 32 are located on the same plane. When winding the line, the broken line 100 is wound around the fixed pulley 31 located above, the movable pulley 32, and the fixed pulley 31 located below in sequence.

[0045] It should be noted that the length direction of the above-mentioned slide rail 21 is as follows: Figure 1 As shown by the arrow a in the middle, the thickness direction of the slide rail 21 is as follows Figure 1 As shown by arrow b in the middle, the height direction is Figure 1 As shown by arrow c.

[0046] In order to facilitate the position arrangement of the first tensioning unit and the second tensioning unit, a first mounting plate 6 for installing the first tensioning unit is provided at the head end of the slide rail 21, and a second mounting plate 7 for installing the second tensioning unit is provided on the slider 22. The second mounting plate 7 is detachably mounted on the slider 22 through a connecting member 8.

[0047] In this embodiment, the first mounting plate 6 includes a connecting inclined plate 61 with one end arranged at the head end of the slide rail 21 and a matching plate 62 arranged on the other end of the connecting inclined plate 61, two fixed pulleys 31 are mounted on the matching plate 62 through a rotating shaft (unnumbered), one end of the second mounting plate 7 is fixed to the slider 22 through a connecting member 8, and the movable pulley 32 is arranged on the other end of the second mounting plate 7 through a rotating shaft (unnumbered), and in the thickness direction of the slide rail 21, the second mounting plate 7 and the matching plate 62 are stacked, and the size of the second mounting plate 7 in the height direction is smaller than the spacing between the two fixed pulleys 31, so that the movable pulley 32 can move between the two fixed pulleys 31. The connecting member 8 can be specifically a bolt, which is a conventional setting. The present application does not specifically limit the structure of the first mounting plate 6 and the second mounting plate 7, which can satisfy the positional relationship between the two fixed pulleys 31 and the movable pulley 32 as described above.

[0048] It should be noted that in the prior art, when the wire is finally reeled in close to the wire net, the operator needs to remove the broken wire from the device and manually slide the broken wire into the wire net, which poses a safety hazard and has a great impact on the wire reeling tension, making the wire reeling unstable.

[0049] By configuring the movable pulley 32 to be movable between the two fixed pulleys 31 along the length direction of the slide rail 21, and in the thickness direction of the slide rail 21, the centers of the two fixed pulleys 31 and the movable pulley 32 are located on the same plane, so that the front end of the broken wire take-up device is a flat structure. During the take-up process, the front end of the broken wire take-up device can enter the wire net so that the broken wire 100 is completely retracted into the wire net. After stopping, the broken wire take-up device can be removed. There is no need for the operator to manually remove the steel wire from the broken wire take-up device to manually slide the broken wire into the wire net. The safety is high, and the take-up tension can be guaranteed to be always stable, thereby ensuring the take-up effect.

[0050] The load component 4 is used to provide a pulling force to the slider 22 . Under the action of the load component 4 , the slider 22 drives the second tensioning unit to move along the track of the slide rail 21 toward the tail end of the slide rail 21 , so that the first tensioning unit cooperates with the second tensioning unit to tension the broken wire 100 .

[0051] Specifically, the load assembly 4 includes a load pulley 41 , a weight member 42 and a pull rope 43 . The load pulley 41 is disposed at the rear end of the slide rail 21 . The weight member 42 is connected to the slide block 22 via the pull rope 43 . The pull rope 43 is laid on the load pulley 41 .

[0052] The pull rope 43 has a first section 431 located between the slider 22 and the load pulley 41 and a second section 432 located between the load pulley 41 and the weight member 42. The first section 431 is parallel to the axis of the slide rail 21, and the second section 432 extends in the height direction under the gravity of the weight member 42. That is, the pulling force of the slider 22 is provided by the gravity of the weight member 42, which can keep the tension stable and ensure the wire collection effect. In addition, in order to simplify the structure of the wire-breaking wire collection device, the pull rope 43 can be connected to the slider 22 through the connecting member 8.

[0053] In this embodiment, the weight-bearing member 42 may be a punched weight or a sandbag, and the weight of the punched weight or the sandbag may be selected in combination with design requirements to meet different requirements for take-up tension. The pull rope 43 may be a steel rope.

[0054] It is worth noting that the wire-breaking and wire-retrieving device in this embodiment is a handheld wire-breaking and wire-retrieving device. Specifically, one end of the support rod 1 is vertically mounted on an end surface of the slide rail 21 away from the slider 22 and extends along the thickness direction of the slide rail 21 .

[0055] The operator can adjust the relative position of the wire-breaking and wire-taking device and the wire net by holding the support rod 1, and make the head end of the wire-breaking and wire-taking device face the wire net. By flexibly changing the position of the wire-breaking and wire-taking device, it can be adapted to complex wire-breaking positions or cutting machine environments.

[0056] When winding the line, the broken line 100 is wound around the upper fixed pulley 31, the movable pulley 32 and the lower fixed pulley 31 in sequence. Under the gravity of the load-bearing member 42, the slider 22 is pulled to drive the movable pulley 32 away from the two fixed pulleys 31 until the broken line 100 is tightened. Then the cutting machine is started to start the winding process. The broken line 100 is gradually tightened under the pulling force of the cutting machine until the slider 22 is pulled to move toward the two fixed pulleys 31 and until the slider abuts against the stopper 5 close to the two fixed pulleys 31 to complete the winding.

[0057] Example 2

[0058] This embodiment provides a broken wire take-up device, which is also used to collect the broken wires of the cutting machine wire net back into the wire net. Figure 2 As shown, the structure of the wire-breaking and wire-taking-up device in this embodiment is similar to the structure of the fixing device in Example 1, with the difference that: the wire-breaking and wire-taking-up device in this embodiment is an adsorption-type wire-breaking and wire-taking-up device, which is suitable for use in scenarios with large installation space and high wire-taking-up tension. It can be fixed on the table of a cutting machine (not shown), without the need for an operator to manually adjust the position of the wire-breaking and wire-taking-up device, so as to be suitable for heavy load-bearing parts.

[0059] Specifically, one end of the support rod 1 is vertically mounted on the slide rail 21 and extends in the height direction, and the other end of the support rod 1 is provided with a magnetic base 20, and a magnetic switch 30 is provided on the magnetic base 20. The magnetic switch 30 is opened or closed to stop or start the magnetic base 20. The magnetic base 20 is a prior art, which uses the principle of electromagnetism to make the magnetic base generate magnetic force to be adsorbed on the table of the cutting machine. It should be noted that the height direction is as follows: Figure 2 As shown by arrow d.

[0060] In order to adapt to wire nets of different heights and make the head end of the broken wire take-up device face the broken wire position, in this embodiment, the slide rail 21 is installed on the support rod 1 through an adjustment mechanism 40, and the adjustment mechanism 40 is used to adjust the relative position of the slide rail 21 and the support rod 1 in the height direction.

[0061] Specifically, the adjustment mechanism 40 includes a fixed rod sleeved on the support rod 1 and a locking member (not numbered) for locking the relative position of the fixed rod (not numbered) and the support rod 1, and the slide rail 21 is installed on the fixed rod. The locking member can be a threaded fastener that passes through the fixed rod to abut against the support rod 1, or a buckle set on the fixed rod, and the buckle can be clamped on the support rod 1 to limit the relative displacement of the fixed rod and the support rod 1. It is a conventional setting and will not be described in detail here.

[0062] Due to the application of the above technical solution, the beneficial effects of the present application compared with the prior art are:

[0063] 1. This application sets a sliding component, a tensioning component and a load component to cooperate to achieve automatic tensioning of the broken wire, without manual intervention by the operator. During the wire-winding process, the operator only needs to control the slicer to observe the wire-winding situation, and the operation has no safety hazards and the wire-winding operation is easy;

[0064] 2. The present application provides pulling force for the slider by setting a load component. Under the action of the load component, the slider drives the second tensioning unit to move along the track of the slide rail toward the tail end of the slide rail, so that the first tensioning unit cooperates with the second tensioning unit to tension the broken wire, so that the wire tension of the broken wire is stable and adjustable, reducing the fluctuation of the wire network tension, so as to avoid secondary wire breakage or poor color difference remaining on the surface of the cut silicon wafer.

[0065] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
