Description

Technical Field

[0001] This utility model relates to the technical field of tungsten wire feeding equipment, specifically a transverse passive adaptive feeding machine. Background Technology

[0002] Silicon wafers, as the basic material for photovoltaic cells, need to be cut using diamond wire. Due to the increasing size and thinning of silicon wafers, the steel wire used to produce diamond wire is gradually being replaced by tungsten wire, which has higher strength and better fatigue and corrosion resistance. Tungsten wire is made by forging and drawing tungsten bars. Existing tungsten wire drawing machines are modified from the original tungsten lamp filament drawing machines. During wire feeding, a passive rotating I-beam reel feeding device is generally used, where the tungsten wire is drawn on the I-beam reel under traction, and the reel rotates passively. However, current tungsten wire feeding devices have the following drawbacks:

[0003] However, due to the increasingly finer diameter of tungsten wire required by the industry, the tungsten wire itself is relatively fragile. When the length of the wire laid exceeds 120 km, the traction force applied to the tungsten wire during laying causes the I-beam reel to rotate passively. This method is prone to wire breakage and is not conducive to production.

[0004] Therefore, we propose a transverse passive adaptive wire feeding machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a transverse passive adaptive wire feeding machine to solve the problems mentioned in the background art.

[0007] Preferably, the end of the double-threaded shaft away from the wire feeding support plate is threadedly sleeved with the I-beam wheel cover plate, the I-beam wheel cover plate contacts the end of the I-beam wheel, and two tensioning shafts are horizontally arranged on the side of the I-beam wheel cover plate near the rotating block.

[0008] Preferably, the rotating block is fixed to a friction wheel near the side of the I-beam wheel cover plate, the friction wheel is provided with a suede belt, two studs are fixed to both ends of the suede belt, and a through hole is opened on the belt shaft, with the studs sleeved in the through hole.

[0009] Preferably, the stud is located on both sides of the belt shaft and two nuts are threaded onto it. The two nuts contact both sides of the belt shaft, and the rough surface of the suede belt contacts the friction wheel.

[0010] Preferably, the I-beam wheel cover plate is horizontally fixed with two bolts at the positions of the two tensioning shafts, the tensioning shaft is threaded with bolts, the end of the double-ended threaded shaft near the I-beam wheel cover plate is threaded with a clamping nut, the clamping nut contacts the I-beam wheel cover plate, the end of the I-beam wheel near the wire feeding support plate is rotatably sleeved with an I-beam wheel positioning plate, and the I-beam wheel positioning plate is threadedly connected to the end of the double-ended threaded shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a rotatable rotating block. A second guide wheel and a first guide wheel are mounted on the rotating block via a rear-end and a front-end wire-feeding support rod. During wire feeding, the tungsten wire is guided out from the second and first guide wheels. When the tungsten wire is subjected to traction, the force on the front-end wire-feeding support rod changes according to the change in the front-end traction speed. This changes the traction force on the rear-end wire-feeding support rod, causing a change in the force on the rear-end wire-feeding support rod. This, in turn, causes the rotating block to rotate faster or slower, matching the traction force and achieving adaptive adjustment. This reduces the pulling force on the tungsten wire, preventing wire breakage and making it more practical. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1-2 This utility model provides a technical solution: a transverse passive adaptive wire feeding machine, including a wire feeding support plate 1, a double-ended threaded shaft 13 horizontally fixed to the top side wall of the wire feeding support plate 1, a I-beam wheel 11 sleeved on the double-ended threaded shaft 13, a wire guide wheel shaft 14 threadedly connected to the end of the double-ended threaded shaft 13 away from the wire feeding support plate 1, a rotating block 6 rotatably sleeved on the wire guide wheel shaft 14, two wire feeding flying arms 3 fixedly connected to the top and bottom surfaces of the rotating block 6, a rear wire feeding support rod 12 horizontally fixedly connected to the end of the wire feeding flying arm 3 away from the rotating block 6 near the I-beam wheel 11, a second guide wheel 10 rotatably connected to the side wall of the end of the rear wire feeding support rod 12 away from the wire feeding flying arm 3, and the side wall of the end of the wire feeding flying arm 3 near the rotating block 6 horizontally... A front-end wire feeding support rod 5 is fixedly connected, and a first guide wheel 4 is rotatably connected to the side wall of the end of the front-end wire feeding support rod 5. A rotatable rotating block 6 is set on the rotating block 6, and a second guide wheel 10 and a first guide wheel 4 are mounted on the rotating block 6 via a rear-end wire feeding support rod 12 and a front-end wire feeding support rod 5. During wire feeding, the tungsten wire is led out from the second guide wheel 10 and the first guide wheel 4. After the tungsten wire is subjected to traction force, the force at the front-end wire feeding support rod 5 changes according to the change of the front-end traction speed. This changes the traction force generated on the rear-end wire feeding, causing a change in the force at the rear-end wire feeding support rod 12. As a result, the rotation speed of the rotating block 6 is increased or decreased. This reduces the pulling force of the traction force on the tungsten wire, avoids wire breakage, and is more practical.

[0021] Example 2:

[0022] Please see Figure 1-3This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The double-headed threaded shaft 13 is threadedly connected to the I-beam wheel cover plate 2 at the end away from the wire feeding support plate 1. The I-beam wheel cover plate 2 contacts the end of the I-beam wheel 11. Two tensioning shafts 8 are horizontally arranged on the side of the I-beam wheel cover plate 2 near the rotating block 6.

[0023] The rotating block 6 is fixed to the friction wheel 7 near the side of the I-beam wheel cover plate 2. The friction wheel 7 is equipped with a suede belt 9. Two studs 19 are fixed to both ends of the suede belt 9. A through hole 20 is opened on the tensioning shaft 8, and the studs 19 are sleeved in the through hole 20.

[0024] The stud 19 is located on both sides of the tension belt shaft 8 and is threaded with two nuts 21. The two nuts 21 contact both sides of the tension belt shaft 8. The rough surface of the suede belt 9 contacts the friction wheel 7. The suede belt 9 can generate friction on the friction wheel 7. In this way, if the equipment with traction applied at the front end stops, the rotating block 6 can be stopped quickly, and the rotating block 6 can be prevented from continuously feeding the wire feeding fly arm 3 due to inertia.

[0025] Two bolts 22 are horizontally fixed to the two tensioning shafts 8 corresponding to the pressure plate 2 of the I-beam wheel. The tensioning shafts 8 are threaded with bolts 22. The end of the double-ended threaded shaft 13 near the pressure plate 2 is threaded with a clamping nut 15. The clamping nut 15 contacts the pressure plate 2 of the I-beam wheel. The end of the I-beam wheel 11 near the wire feeding support plate 1 is rotated and sleeved with the I-beam wheel positioning plate 18. The I-beam wheel positioning plate 18 is threadedly connected to the end of the double-ended threaded shaft 13.

[0026] The rotating block 6 is fixedly sleeved with a bearing housing 16, the bearing housing 16 is fixedly sleeved with the inner ring of the deep groove ball bearing 17, and the outer ring of the deep groove ball bearing 17 is fixedly sleeved with the rotating block 6.

[0027] Example 3:

[0028] Please see Figure 1-3 This is the third embodiment of the present invention, based on the above two embodiments. In use, the wire feeding support plate 1 is installed on the wire drawing machine. The tungsten wire is fed from the I-beam wheel 11 and guided by the first guide wheel 4 and the second guide wheel 10, connecting to the front-end equipment. The front-end equipment then applies traction to achieve wire feeding. The present invention includes a rotatable rotating block 6. The rotating block 6 is equipped with the second guide wheel 10 and the first guide wheel 4 via the rear-end wire feeding support rod 12 and the front-end wire feeding support rod 5. During wire feeding, the tungsten wire is guided from the second guide wheel 10 and the first guide wheel 4. After the tungsten wire is subjected to traction, the force on the front-end wire feeding support rod 5 changes according to the change in the front-end traction speed, resulting in a change in the traction force on the rear-end wire feeding, which in turn changes the force on the rear-end wire feeding support rod 12. This causes the rotation speed of the rotating block 6 to increase or decrease, matching the traction force and achieving adaptive adjustment. This reduces the pulling force on the tungsten wire, preventing wire breakage and making it more practical.

[0029] 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.
