[0028] 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.
[0029] Example 1
[0030] refer to Figures 1-3 A copper foil surface copper shavings cleaning device includes a winding mechanism 1, a fixed platform 2 and an unwinding mechanism 3 arranged in sequence. The unwinding mechanism 3 is provided with a cutting mechanism 4 for cutting copper foil 101. The copper foil 101 passes over the fixed platform 2. The device also includes a side plate 5 and a blower mechanism 6.
[0031] The side plate 5 is disposed on the side wall of the fixed platform 2 facing away from the copper foil 101 conveying direction. The middle part of the side wall of the side plate 5 near the fixed platform 2 is recessed in the direction away from the fixed platform 2 to form a concave wall 51.
[0032] The top of the concave wall 51 is higher than the top of the fixed platform 2, and an inlet 8 is formed between the top of the concave wall 51 and the top of the fixed platform 2. The output end of the blower mechanism 6 and the inlet 8 are respectively located on both sides along the winding direction of the copper foil 101.
[0033] A drawer 7 is slidably connected to the bottom of the fixed platform 2, and the bottom end of the concave wall 51 is located above the drawer 7;
[0034] The side of the fixed platform 2 opposite to the concave wall 51 is the open side 23. The concave wall 51 and the open side 23 cooperate to form a drop channel 9 that communicates with the entrance 8. The blower mechanism 6 is used to blow shavings off the surface of the copper foil 101 so that the copper shavings enter the drop channel 9 and fall into the drawer 7 for collection.
[0035] The cutting mechanism 4 has been disclosed in Chinese patent CN218224868U, so the structure of the cutting mechanism 4 will not be described in detail in this embodiment.
[0036] It should be noted here that the blower mechanism 6 can use a fan.
[0037] In this design, the copper foil roll 101 is placed on the unwinding mechanism 3. The free end of the copper foil roll 101 is connected to the winding mechanism 1 after passing through the cutting mechanism 4 on the top of the fixed platform 2. The copper foil 101 is cut by the cutting mechanism 4. The copper shavings generated after the copper foil 101 is cut by the cutting mechanism 4 are blown off the surface of the copper foil 101 by the blower mechanism 6. The blower mechanism 6 blows the copper shavings towards the inlet 8. After entering from the inlet 8, the copper shavings fall into the drop channel 9 formed by the concave wall 51 and the open side 23. After passing through the drop channel 9, the copper shavings fall into the drawer 7 for collection. In this way, when the blower mechanism 6 cleans the surface of the copper foil 101 for copper shavings, the concave wall 51 can prevent the copper shavings from bouncing back and make it easier for them to fall into the drawer 7 for collection.
[0038] In this embodiment, a filter screen 21 is provided on the side of the fixed platform 2 near the blower mechanism 6.
[0039] Generally, in order to prevent the blower mechanism 6 from blowing up the copper shavings in the drawer 7, a filter screen 21 is installed on the side of the fixed platform 2 near the blower mechanism 6. When the blower mechanism 6 blows the copper foil 101, the air will flow out from the holes of the filter screen 21 and the copper shavings will be intercepted by the filter screen 21 to prevent the flowing air from carrying the copper shavings to the external environment.
[0040] Preferably, the fixed platform 2 is provided with a protrusion 22 on the side near the blower mechanism 6, the top of the protrusion 22 is higher than the top of the fixed platform 2, the copper foil 101 passes between the protrusion 22 and the inlet 8, and the upper surface of the copper foil 101 is lower than the top of the protrusion 22.
[0041] The protrusion 22 has the same length as the fixed platform 2.
[0042] Generally, one side of the copper foil 101 will be close to the side of the bump 22, so that when the blower mechanism 6 blows the shavings off the surface of the copper foil 101, the degree of shaking of the copper foil 101 can be reduced.
[0043] Preferably, the concave wall 51 is an arc-shaped wall. When the blower mechanism blows shavings off the surface of the copper foil 101, the arc-shaped wall can better prevent the copper shavings from hitting the wall and bouncing out.
[0044] Preferably, the bottom end of the side panel 5 is provided with a clamping part 52 for clamping one end of the drawer 7. When the drawer 7 is inserted, one end of the drawer 7 can be positioned by clamping against the clamping part 52.
[0045] More preferably, the output end of the blower mechanism 6 is tilted downward toward the top of the fixed platform 2. By tilting the output end of the blower mechanism 6 downward toward the top of the fixed platform 2, the degree of swaying of the copper foil 101 during the winding process can be reduced.
[0046] Preferably, the winding mechanism 1 includes a first frame 11, a winding roller 13 and a first auxiliary roller 12 disposed on the first frame 11, a first motor 14 disposed on the first frame 11, and one end of the winding roller 13 is connected to the output end of the first motor 14.
[0047] The unwinding mechanism 3 includes a second frame 31, an unwinding roller 32, a second auxiliary roller 33, and a third auxiliary roller 34. The unwinding roller 32, the second auxiliary roller 33, the cutting mechanism 4, and the third auxiliary roller 34 are arranged sequentially on the second frame 31 along the winding direction of the copper foil 101. A second motor 35 is also provided on the second frame 31. One end of the unwinding roller 32 is connected to the output end of the second motor 35. The fixed platform 2 is located between the first auxiliary roller 12 and the third auxiliary roller 34.
[0048] Specifically, the heights of the first auxiliary roller 1 and the third auxiliary roller 32 are the same, so that the copper foil 101 can pass straight over the top of the fixed platform. The copper foil 101 is rolled onto the unwinding roller 32, and the free end of the copper foil 101 roll passes sequentially through the second auxiliary roller 33, the cutting mechanism 4, the third auxiliary roller 34, the top of the fixed platform 2 and the first auxiliary roller 12 before being connected to the take-up roller 13. The first motor 14 drives the take-up roller 13 to rotate, and the second motor 35 drives the unwinding roller 32 to rotate. During the winding process, the copper foil 101 is cut by the cutting mechanism 4.
[0049] Preferably, the top of the protrusion is provided with an inverted U-shaped housing, one side of which is connected to the side wall of the side plate. The housing prevents copper shavings from escaping into the external environment.
[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
