Description

Technical Field

[0001] This utility model relates to the field of electrode production equipment technology, and more specifically, to an edge trimming device and electrode production equipment. Background Technology

[0002] In related technologies, during dry film formation processes, dry powder is pressed into films using rollers. However, the edges of these roller-formed films are irregular, making it difficult to ensure alignment when laminating them with a current collector. Therefore, a film trimming process is required before the lamination of the film and current collector. Current trimming devices use circular cutters with motor-controlled positions to ensure the cutter precisely cuts the film without scratching the rollers. However, the distance between the cutter and the rollers is difficult to maintain with high precision, resulting in poor trimming quality.

[0003] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0041] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0042] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0044] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] According to one embodiment of this application, a cutting mechanism is provided. For example... Figures 1 to 7 As shown, the cutting mechanism 1 includes a first connecting member 11, a second connecting member 12, and a first elastic member 13. The second connecting member 12 and the first connecting member 11 are elastically connected through the first elastic member 13. A cutter 14 is mounted on the second connecting member 12. The first elastic member 13 can push the second connecting member 12 relative to the first connecting member 11 to apply pressure to the cutter 14.

[0047] In this example, the cutter 14 is mounted on the second connector 12. For example, the cutter 14 can be pressed against the second connector 12 by the first pressure block 103. The second connector 12 and the first connector 11 are elastically connected by the first elastic member 13. The first elastic member 13 can push the second connector 12 relative to the first connector 11, thereby applying pressure to the cutter 14 so that the cutter 14 can more stably abut against the roller 5, thereby improving the material cutting effect.

[0048] In this example, the cutting mechanism 1 can be used in electrode production equipment. Dry powder falls into the gap between two rollers 5, and the powder is pressed into a film 6 by the rollers 5. The cutter 14 mechanism can be located on the lower side of the rollers 5. The cutter 14 presses the surface of the rollers 5 under the action of the first elastic member 13. The film 6 is attached to the surface of the rollers 5 and rotates with them. After the film 6 touches the cutter 14, it is cut into a valid film 6 and a waste edge. The valid film 6 is attached to the rollers 5 and enters the next process, while the waste edge can be peeled off and collected in a waste box. The cutter 14 can be a straight cutter 14 that directly presses the surface of the rollers 5.

[0049] In one example, such as Figure 3 and Figure 4 As shown, the cutting mechanism 1 also includes a first guide rod 15, one of the first connecting member 11 and the second connecting member 12 is slidably connected to the first guide rod 15, and the other is fixedly connected to the first guide rod 15.

[0050] like Figure 3 and Figure 4 As shown, in this example, the first guide rod 15 can be fixedly disposed relative to the second connector 12, and the first guide rod 15 is slidably disposed relative to the first connector 11. The first elastic member 13 has a tendency to push the second connector 12 away from the first connector 11, thereby applying pressure to the cutter 14 so that the cutter 14 can be stably pressed against the roller 5, thereby improving the cutting effect. The first connector 11 and the second connector 12 are connected by the first guide rod 15, thereby improving the stability of the pressure applied by the second connector 12 to the cutter 14.

[0051] like Figure 4 As shown, in this example, a first sliding sleeve 105 is provided between the first guide rod 15 and the first connecting member 11, thereby improving the smoothness of the sliding of the first guide rod 15 relative to the first connecting member 11. The first sliding sleeve 105 can be a steel ball bushing or a sliding bearing, etc., which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0052] Alternatively, the first guide rod 15 may be fixedly disposed relative to the first connecting member 11, and the first guide rod 15 may be slidably disposed relative to the second connecting member 12. Those skilled in the art can determine this according to the actual situation, and no specific limitations are made here.

[0053] In one example, such as Figure 3 and Figure 4 As shown, the first elastic member 13 is sleeved on the first guide rod 15, one end of the first elastic member 13 abuts against the first connecting member 11, and the other end abuts against the second connecting member 12.

[0054] like Figure 3 and Figure 4 As shown, the first elastic element 13 can be a compression spring, and it is sleeved on the outer periphery of the first guide rod 15. The first elastic element 13 can be located between the first connecting member 11 and the second connecting member 12, with one end of the first elastic element 13 abutting against the first connecting member 11 and the other end abutting against the second connecting member 12. By sleeved the first elastic element 13 on the first guide rod 15, the stability of the pressure applied by the first elastic element 13 to the second connecting member 12 can be improved. Springs with different stiffness and compression can be replaced, or a shim can be provided at one end of the spring to change the elasticity of the first elastic element 23, thereby adjusting the pressure of the cutter 14 on the roll.

[0055] In one example, such as Figure 3 and Figure 4 As shown, the cutting mechanism 1 also includes a first limiting member 16. Multiple first guide rods 15 are provided. One end of each of the multiple first guide rods 15 slides through the first connecting member 11 and is connected to the first limiting member 16 to restrict the first guide rods 15 from disengaging from the first connecting member 11.

[0056] like Figure 3 and Figure 4 As shown, the first limiting member 16 is located on the side of the first connecting member 11 opposite to the second connecting member 12. The end of the first guide rod 15 away from the second connecting member 12 can slide through the first connecting member 11 and be connected to the first limiting member 16. The first limiting member 16 can simultaneously prevent multiple first guide rods 15 from detaching from the first connecting member 11. For example, the first limiting member 16 can be a limiting block structure, and one end of the first guide rod 15 can be connected to the first limiting member 16 by fasteners such as screws or bolts.

[0057] like Figure 3 As shown, in this example, the cutting mechanism 1 further includes a first fixing member 19, which can assemble the first limiting member 16 to the first connecting member 11, and the first limiting member 16 can move relative to the first fixing member 19. For example, the first fixing member 19 can be a fastener such as a screw.

[0058] In such Figure 3 and Figure 4 As shown, in this example, multiple first guide rods 15 can be provided, and each first guide rod 15 is fitted with a first elastic element 13. The cutter 14 is installed on the second connecting member 12 and is located in the middle of the multiple first elastic elements 13 to make the pressure on the cutter 14 more uniform. For example, two first elastic elements 13 are spaced apart, and the cutter 14 is located in the middle between the two first elastic elements 13. Of course, more first elastic elements 13 can also be provided, for example, three or four first elastic elements 13, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0059] In one example, such as Figure 3 and Figure 4 As shown, the cutting mechanism 1 also includes a first mounting base 17, and the first connecting member 11 is adjustablely connected to the first mounting base 17. The first connecting member 11 can be adjusted to face or move away from the second connecting member 12.

[0060] like Figure 3 and Figure 4 As shown, in this example, the first mounting base 17 is fixedly installed, and the first connecting member 11 is adjustablely installed on the first mounting base 17, thereby adjusting the pressure applied by the first elastic member 13 to the second connecting member 12 to adjust the pressure of the cutter 14 pressing against the surface of the roll 5.

[0061] In this example, one end of the first elastic member 13 abuts against the first connecting member 11, and the other end abuts against the second connecting member 12. The first connecting member 11 can be adjusted toward the second connecting member 12, thereby increasing the pressure of the first elastic member 13 on the second connecting member 12, thus increasing the pressure of the cutter 14 on the roll 5. The first connecting member 11 can also be adjusted away from the second connecting member 12, thereby decreasing the pressure of the first elastic member 13 on the second connecting member 12, thus decreasing the pressure of the cutter 14 on the roll 5.

[0062] like Figure 3 and Figure 4 As shown, in this example, the first connector 11 is provided with a connecting hole 111, which may be oblong in shape and positioned along the extension and retraction direction of the first elastic member 13. The first connector 11 can be connected to the first mounting base 17 by fasteners such as studs or screws. That is, one end of the fastener can pass through the connecting hole 111 and be screwed to the first mounting base 17. The fastener can move along the connecting hole 111, thereby adjusting the position of the first connector 11 relative to the first mounting base 17 to adjust the pressure of the first elastic member 13 on the second connector 12. Alternatively, the connecting hole 111 may also be provided on the first mounting base 17. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0063] In one example, such as Figure 1 and Figure 2 As shown, the cutting mechanism 1 also includes a drive mechanism 3, and the first mounting base 17 is tractively connected to the drive mechanism 3, which can drive the first mounting base 17 to move.

[0064] like Figure 1 and Figure 2 As shown, the first connector 11 is connected to the first mounting base 17, the cutter 14 is mounted on the second connector 12, and the drive mechanism 3 can drive the first mounting base 17 to move, thereby driving the cutter 14 to move, so as to adjust the position of the cutter 14.

[0065] like Figure 1 and Figure 2 As shown, in this example, the drive mechanism 3 may include a lead screw 34, which is connected to the first mounting base 17. Rotation of the lead screw 34 drives the first mounting base 17 to move. The lead screw 34 has a simple structure and transmission method, and is easy to assemble.

[0066] It should be noted that two cutters 14 can be provided, with two sets of first connecting members 11 and second connecting members 12 corresponding to each other. Each set of first connecting members 11 and second connecting members 12 is suitable for assembling one cutter 14. Each first connecting member 11 is connected to a first mounting base 17. The lead screw 34 can be a double-acting lead screw 34, with one first mounting base 17 being drivenly connected to the right-hand thread of the double-acting lead screw 34, and the other first mounting base 17 being drivenly connected to the left-hand thread of the double-acting lead screw 34. By rotating the double-acting lead screw 34, the distance between the two cutters 14 can be adjusted.

[0067] In one example, the drive mechanism 3 also includes a handwheel 37, which is drively connected to the lead screw 34. The lead screw 34 is rotated by turning the handwheel 37.

[0068] The handwheel 37 can be directly mounted on one end of the lead screw 34. The operator can rotate the handwheel 37 to drive the lead screw 34. Alternatively, the handwheel 37 can be connected to the lead screw 34 via a rotating shaft 36. That is, one end of the rotating shaft 36 is connected to one end of the lead screw 34, and the other end is connected to the handwheel 37. Rotating the handwheel 37 will drive the rotating shaft 36 to rotate, thereby driving the lead screw 34 to rotate.

[0069] In one example, such as Figure 1 and Figure 2As shown, the drive mechanism 3 includes a position display 31, which is adapted to display the position of the first mounting base 17. By displaying the position of the first mounting base 17 on the position display 31, the position of the cutter 14 can be precisely adjusted.

[0070] For example, such as Figure 1 and Figure 2 As shown, the handwheel 37 can be connected to the lead screw 34 via the drive shaft 36. That is, one end of the drive shaft 36 is connected to one end of the lead screw 34, and the other end of the drive shaft 36 is connected to the handwheel 37. By rotating the handwheel 37, the lead screw 34 can be driven to rotate. The position display 31 can be fitted onto the drive shaft 36. The position display 31 can record the number of rotations of the handwheel 37. Combined with the lead screw lead, the current position of the cutter 14 or the distance between two cutters 14 can be accurately calculated.

[0071] like Figure 2 As shown, in this example, the drive mechanism 3 also includes a locking member 39. After the position of the cutter 14 is adjusted, the locking member 39 can lock the drive shaft 36. For example, the locking member 39 can be a clamping member that works with a locking screw. The clamping member is sleeved on the drive shaft 36. After the position of the cutter 14 is adjusted, the locking screw on the clamping member is tightened, and the clamping member holds the drive shaft 36 tightly, ensuring that the position of the cutter 14 is stable in the working state.

[0072] In one example, such as Figure 3 and Figure 4 As shown, the cutting mechanism 1 also includes a brush 18, which is rotatably mounted on the second connector 12 and located on one side of the cutter 14.

[0073] like Figure 3 and Figure 4 As shown, the brush 18 is rotatably mounted on the second connector 12, and the brush 18 can be located on one side of the cutter 14. After the cutter 14 has finished cutting the material, the brush 18 can brush the cut material off the roller 5. The second connector 12 also houses a motor 101, with one end of a chuck 102 clamping the output shaft of the motor 101 and the other end clamping the shaft of the brush 18, so that the motor 101 can drive the brush 18 to rotate via the chuck 102.

[0074] It should be noted that when cutting the diaphragm 6 on the roller 5, only the brush 18 on one side of the cutter 14 needs to be retained, and the brush 18 on this side can brush away the waste edges generated after cutting. The other side does not have a brush 18 to avoid damaging the effective diaphragm. Alternatively, in other usage environments, brushes 18 can be provided on both sides of the cutter 14. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0075] In this example, a dust cover 104 is also provided on the second connector 12. The dust cover 104 can be fixedly connected to the surface of the second connector 12 by fasteners such as screws or studs, which can play a role in preventing dust and avoid the accumulation of waste material brushed off by the brush 18 on the second connector 12, making it inconvenient to clean.

[0076] According to another embodiment of this application, a trimming device is provided. This trimming device includes the cutting mechanism described in the above embodiment. The trimming device is capable of removing the waste edge of the film 6 on the roller 5. The cutting mechanism 1 includes a first connecting member 11, a second connecting member 12, a first elastic member 13, and a cutter 14. The second connecting member 12 and the first connecting member 11 are elastically connected via the first elastic member 13. The cutter 14 is mounted on the second connecting member 12, and the first elastic member 13 can push the second connecting member 12 relative to the first connecting member 11 to apply pressure to the cutter 14. The cutter 14 is mounted on the second connecting member 12, and the second connecting member 12 and the first connecting member 11 are elastically connected via the first elastic member 13. The first elastic member 13 can push the second connecting member 12 relative to the first connecting member 11, thereby applying pressure to the cutter 14 so that the cutter 14 can more stably abut against the roller 5, thereby improving the waste edge removal effect.

[0077] In one example, such as Figures 5 to 7 As shown, the cutting device also includes a scraping mechanism 2, which is located on one side of the cutting mechanism 1. The scraping mechanism 2 can scrape off the material cut by the cutter 14.

[0078] like Figure 7 As shown, the arrow indicates the rotation direction of the roller 5, that is, the roller 5 rotates counterclockwise, and the surface of the roller 5 is adhered with a film 6. The film 6 can first contact the cutter 14, thereby being cut into waste edges and effective film 6. The brush 18 can clean the waste edges. The waste edges that the brush 18 does not brush off are rotated with the roller 5 to the position of the scraping mechanism 2, so that the scraping mechanism 2 can scrape off the waste material of the roller 5.

[0079] In one example, such as Figure 5 and Figure 6 As shown, the scraping mechanism 2 includes a third connector 21, a fourth connector 22, and a second elastic member 23. The third connector 21 and the fourth connector 22 are elastically connected by the second elastic member 23. A scraper 24 is mounted on the fourth connector 22. The second elastic member 23 can push the fourth connector 22 relative to the third connector 21 to apply pressure to the scraper 24.

[0080] like Figure 5 and Figure 6As shown, in this example, the third connector 21 and the fourth connector 22 are elastically connected by a second elastic member 23. The scraper 24 is connected to the fourth connector 22; for example, the scraper 24 can be pressed against the fourth connector 22 by a second pressure block 26. The second elastic member 23 can push the fourth connector 22 relative to the third connector 21 to apply pressure to the scraper 24, thereby enabling the scraper 24 to stably abut against the surface of the roll 5 to improve the scraping effect.

[0081] In one example, the scraping mechanism 2 further includes a second guide rod 27 and a second limiting member 28. One end of the second guide rod 27 passes through the third connecting member 21 and is connected to the second limiting member 28. The second elastic member 23 is sleeved on the second guide rod 27.

[0082] like Figure 5 and Figure 6 As shown, in this example, one end of the second guide rod 27 passes through the third connector 21 and is connected to the second limiting member 28. The second limiting member 28 can play a limiting role to prevent the second guide rod 27 from disengaging from the third connector 21.

[0083] The third connecting member 21 and the fourth connecting member 22 are slidably connected relative to each other via a second guide rod 27. The second guide rod 27 can be fixed relative to the fourth connecting member 22 and slidably positioned relative to the third connecting member 21. The second elastic member 23 has a tendency to push the fourth connecting member 22 away from the third connecting member 21, thereby applying pressure to the scraper 24 so that the scraper 24 can be stably pressed against the roller 5, thus improving the scraping effect. The connection between the third connecting member 21 and the fourth connecting member 22 via the second guide rod 27 improves the stability of the pressure applied by the fourth connecting member 22 to the scraper 24. A second sliding sleeve 201 is provided between the second guide rod 27 and the third connecting member 21, thereby improving the smoothness of the sliding of the second guide rod 27 relative to the third connecting member 21. The second sliding sleeve 201 can be a steel ball bushing or a sliding bearing, etc., which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0084] The second elastic element 23 can be a compression spring, and it is sleeved on the outer periphery of the second guide rod 27. The second elastic element 23 can be located between the third connecting member 21 and the fourth connecting member 22, with one end abutting against the third connecting member 21 and the other end abutting against the fourth connecting member 22. By sleeved on the second guide rod 27, the stability of the pressure applied by the second elastic element 23 to the fourth connecting member 22 can be improved. Springs with different stiffness and compression can be replaced, or a shim can be added to one end of the spring to change the elasticity of the second elastic element 23, thereby adjusting the pressure of the scraper 24 on the roll.

[0085] In this example, the third connector 21 is positioned on the movable base 32. For example, the movable base 32 has a slotted hole arranged along the extension / retraction direction of the second elastic member 23. The third connector 21 can be connected to the movable base 32 by fasteners such as studs or screws. That is, one end of the fastener can pass through the slotted hole and be screwed to the third connector 21. The fastener can move along the slotted hole, thereby adjusting the position of the third connector 21 relative to the movable base 32, and thus adjusting the pressure of the second elastic member 23 on the fourth connector 22.

[0086] like Figure 5 and Figure 6 As shown, in this example, multiple second guide rods 27 can be provided. One end of each second guide rod 27 slides through the third connector 21 and is connected to the second limiting member 28 to prevent the second guide rod 27 from detaching from the third connector 21. The second limiting member 28 is located on the side of the third connector 21 opposite to the fourth connector 22. The end of the second guide rod 27 away from the fourth connector 22 can slide through the third connector 21 and be connected to the second limiting member 28. The second limiting member 28 can simultaneously prevent multiple second guide rods 27 from detaching from the third connector 21. For example, the second limiting member 28 can be a limiting block structure, and one end of the second guide rod 27 can be connected to the second limiting member 28 by fasteners such as screws or bolts.

[0087] like Figure 5 and Figure 6 As shown, in this example, the scraping mechanism 2 further includes a second fixing member 29, which is adapted to connect the second limiting member 28 to the third connecting member 21. The second fixing member 29 can assemble the second limiting member 28 to the third connecting member 21, and the second limiting member 28 can move relative to the second fixing member 29. For example, the second fixing member 29 can be a fastener such as a screw.

[0088] In one example, such as Figure 1 and Figure 7 As shown, the scraping mechanism 2 also includes a guide groove 25, which is located below the scraper 24 and can receive the material hanging off the scraper 24.

[0089] like Figure 1 and Figure 7As shown, in this example, the guide trough 25 can be mounted on the movable base 32, and the guide trough 25 is inclined. One end of the guide trough 25 is located below the scraper 24, and the other end extends downwards at an angle to the waste box. After the scraper 24 scrapes the waste off the roller 5, it can fall into the guide trough 25 and then slide downwards along the guide trough 25 into the waste box. By setting the guide trough 25, waste can be effectively collected to avoid contamination of the scraping device by the waste.

[0090] In one example, such as Figure 2 and Figure 7 As shown, the edge trimming device also includes a movable base 32, on which the cutting mechanism 1 and the scraping mechanism 2 are respectively mounted. The movable base 32 can drive the cutting mechanism 1 and the scraping mechanism 2 to move.

[0091] like Figure 2 and Figure 7 As shown, in this example, the first mounting base 17 of the cutting mechanism 1 is mounted on the movable base 32. The third connecting member 21 of the scraping mechanism 2 is mounted on the movable base 32. The movable base 32 is connected to the drive mechanism 3 in a transmission manner; for example, the movable base 32 is screwed to the lead screw 34 of the drive mechanism 3. The lead screw 34 drives the movable base 32 to move, thereby driving the cutting mechanism 1 and the scraping mechanism 2 to move.

[0092] In this example, multiple sets of cutting mechanism 1 and scraping mechanism 2 can be provided, and multiple moving seats 32 are correspondingly provided. Each moving seat 32 is equipped with a corresponding set of cutting mechanism 1 and scraping mechanism 2. For example, there are two sets of cutting mechanism 1 and scraping mechanism 2, and two moving seats 32 are correspondingly provided. The lead screw 34 is a bidirectional lead screw 34, and the two moving seats 32 are respectively screwed to the right-hand thread and the left-hand thread of the bidirectional lead screw 34 to adjust the distance between the two sets of cutting mechanism 1 and scraping mechanism 2.

[0093] like Figure 1 , Figure 2 and Figure 7 As shown, in this example, the drive mechanism 3 also includes a second mounting base 35, on which a guide member 33 is provided. For example, the guide member 33 can be a guide rail or a guide groove. The movable seat 32 is slidably disposed on the guide member 33. The second mounting base 35 is also provided with a plurality of bearing seats 38. The lead screw 34 is screwed through the movable seat 32 and rotatably connected to the bearing seats 38 to improve the smoothness of the rotation of the lead screw 34. The drive shaft 36 can also be mounted on the bearing seats 38, and the locking member 39 can be mounted on the bearing seats 38 and sleeved on the drive shaft 36.

[0094] like Figure 1 and Figure 2As shown, the second mounting base 35 is also covered with a bellows cover 4. The bellows cover 4 can cover the outer periphery of components such as the moving base 32, the lead screw 34 and the guide member 33, thereby preventing waste from falling onto the moving base 32, the lead screw 34 and the guide member 33, thereby affecting the driving performance of the drive mechanism 3.
