Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a coating equipment for lithium battery manufacturing. Background Technology

[0002] The new energy lithium battery coating machine is a high-precision equipment specially designed to manufacture lithium battery electrodes. Its working principle is to coat electrode materials, such as polymers and carbonates, onto the surface of aluminum or copper foil to form an anode or cathode for use in the manufacture of lithium-ion batteries.

[0003] When coating the surface of aluminum or copper foil, the aluminum or copper foil needs to be stretched and straightened first by an auxiliary roller, and then coated by a coating roller. However, during the movement of the aluminum or copper foil on the auxiliary roller, it is easy for it to deviate, which may cause the aluminum or copper foil to fold, affecting the normal coating process. Utility Model Content

[0004] This invention provides a coating equipment for lithium battery manufacturing to address the problem that aluminum or copper foils are prone to shifting on the auxiliary rollers during movement, which may lead to folding and affect the normal coating process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coating equipment for lithium battery manufacturing, comprising two side plates, a conveyor belt disposed between the two side plates, rollers symmetrically disposed on the inner wall of the conveyor belt, the two ends of the rollers being rotatably connected to the inner walls of the two side plates respectively, a motor disposed on one side of one of the side plates, the output end of the motor passing through the inner wall of the side plate and fixedly connected to one end of one of the rollers, a base fixedly connected to the bottom of the two side plates, rollers disposed at the four corners of the bottom of the base, a positioning device disposed in the middle of the bottom of the base, an extension block fixedly connected to one side of the top of each of the two side plates, and a common auxiliary... An auxiliary roller is provided with a limiting device on its outer surface. The limiting device includes a first threaded rod and a second threaded rod, which are respectively disposed on the inner walls of two extension blocks. The ends of the first and second threaded rods that are close to each other are fixedly connected. The threads of the first and second threaded rods are of the same size but opposite in direction. The outer surfaces of the first and second threaded rods are threaded with threaded hole blocks. A limiting block is fixedly connected to one side of the threaded hole block. The inner wall of the limiting block is slidably connected to the outer surface of the auxiliary roller. The middle of the top of the two side plates is fixedly connected to the same bracket. The inner wall of the bracket is slidably connected to the same lifting frame. A coating roller is provided at the bottom of the lifting frame.

[0006] The effect achieved by the above-mentioned components is as follows: by setting two limiting blocks, under the action of the first threaded rod and the second threaded rod respectively, rotating the first threaded rod and the second threaded rod will drive a limiting block connected to the screw hole block to move until one side of the two limiting blocks is about to abut against the two sides of the aluminum foil or gold foil respectively. This can limit the aluminum foil or gold foil, which helps to prevent the aluminum foil or copper foil from shifting during the movement on the auxiliary roller, thereby preventing the aluminum foil and copper foil from folding and facilitating the normal coating of the aluminum foil and copper foil.

[0007] Preferably, the outer surfaces of both the first and second threaded rods are fixedly connected to bearings, and the outer surfaces of the bearings are fixedly connected to the inner wall of the extension block.

[0008] The effect achieved by the above components is that by setting bearings, the friction between the first and second threaded rods and the extension block can be reduced when rotating the first and second threaded rods, thereby making it easier to rotate the first and second threaded rods.

[0009] Preferably, an operating block is fixedly connected to the ends of the first threaded rod and the second threaded rod that are far apart from each other, and the outer surface of the operating block is provided with a protrusion.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, nuts are provided on both sides of the screw hole block, and the four nuts are symmetrically threaded to the outer surfaces of the first threaded rod and the second threaded rod, respectively.

[0012] The effect achieved by the above-mentioned components is as follows: by setting two nuts and rotating the two nuts so that one side of the two nuts abuts against the two sides of the screw hole block, the two screw hole blocks can be auxiliaryly fixed to the first threaded rod and the second threaded rod respectively, which helps to prevent the screw hole blocks from easily shifting.

[0013] Preferably, a rubber plate is provided on the side of each of the two limiting plates that are close to each other, and one side of the rubber plate is fixedly connected to one side of the limiting block.

[0014] The effect achieved by the above-mentioned components is that by setting a rubber plate, one side of the limiting plate can be attached to the side of the aluminum foil and copper foil, thereby providing a certain degree of protection for the aluminum foil and copper foil.

[0015] Preferably, the positioning device includes a positioning plate, which is disposed in the middle of the bottom of the base. A round rod is symmetrically fixedly connected to the top of the base. A connecting block is slidably connected to the outer surface of the round rod. One side of the two connecting blocks is symmetrically fixedly connected to the two sides of the base.

[0016] The effect achieved by the above components is as follows: by setting up a positioning plate, pushing the positioning plate to drive the round rod to slide on the inner wall of the connecting block until the bottom of the positioning plate abuts against the ground, the support area and friction between the coating equipment and the ground can be increased, which helps to prevent the coating equipment from easily shifting and tipping over.

[0017] Preferably, a circular hole block is fixedly connected to one side of the connecting block, and two insertion holes are opened on the outer surface of the circular rod. The same pin is inserted into the inner wall of the circular hole block and one of the insertion holes.

[0018] The effect achieved by the above components is that by setting a pin and inserting the pin into the inner wall of the round hole block and the corresponding insertion hole, the positioning plate can be fixed.

[0019] Preferably, one end of the pin is fixedly connected to an auxiliary block, and a spring is sleeved on the outer surface of the pin. One end of the spring is fixedly connected to one side of the round hole block, and the other end of the spring is fixedly connected to one side of the auxiliary block.

[0020] The effect achieved by the above components is that by setting a spring, the auxiliary block connected to the pin and the round hole block can be connected, which helps to prevent the pin from easily detaching from the socket and the round hole block and being easily lost.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting two limiting blocks, the first threaded rod and the second threaded rod can respectively drive a limiting block connected to the threaded hole block to move until one side of the two limiting blocks is about to abut against the two sides of the aluminum foil or gold foil, thus limiting the aluminum foil or gold foil. This helps to prevent the aluminum foil or copper foil from shifting during the movement on the auxiliary roller, thereby preventing the aluminum foil and copper foil from folding and facilitating the normal coating of the aluminum foil and copper foil.

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a coating equipment for lithium battery manufacturing, including two side plates 1, a conveyor belt 2 between the two side plates 1, rollers 3 symmetrically arranged on the inner wall of the conveyor belt 2, the two ends of the rollers 3 being rotatably connected to the inner walls of the two side plates 1 respectively, a motor 4 being arranged on one side of one of the side plates 1, the output end of the motor 4 passing through the inner wall of the side plate 1 and fixedly connected to one end of one of the rollers 3, a base 7 being fixedly connected to the bottom of the two side plates 1, rollers 13 being arranged at the four corners of the bottom of the base 7, a positioning device 6 being arranged in the middle of the bottom of the base 7, an extension block 8 being fixedly connected to one side of the top of the two side plates 1, the same auxiliary roller 9 being rotatably connected to the inner wall of the two extension blocks 8, a limiting device 5 being arranged on the outer surface of the auxiliary roller 9, the limiting device 5 including a first threaded rod 51 and a second threaded rod 52, the first threaded rod 51 and the second threaded rod 52 being respectively arranged on the inner wall of the two extension blocks 8, the ends of the first threaded rod 51 and the second threaded rod 52 being fixedly connected to each other, the first threaded rod 51 and the second threaded rod 52 being fixedly connected to each other. The threads are of the same size but opposite in direction. The outer surfaces of the first threaded rod 51 and the second threaded rod 52 are both threaded with threaded hole blocks 53. A limiting block 54 is fixedly connected to one side of each threaded hole block 53. The inner wall of the limiting block 54 is slidably connected to the outer surface of the auxiliary roller 9. The middle of the top of the two side plates 1 is fixedly connected to the same bracket 10. The inner wall of the bracket 10 is slidably connected to the same lifting frame 11. A coating roller 12 is installed at the bottom of the lifting frame 11. By setting two limiting blocks 54, respectively on the first threaded rod 51 and the second threaded rod 52... Under the action of the two threaded rods 52, the first threaded rod 51 and the second threaded rod 52 are rotated. The first threaded rod 51 and the second threaded rod 52 will respectively drive a limiting block 54 connected to the screw hole block 53 to move until one side of the two limiting blocks 54 is about to abut against the two sides of the aluminum foil or gold foil. This can limit the aluminum foil or gold foil, which helps to prevent the aluminum foil or copper foil from shifting during the movement on the auxiliary roller 9, thereby preventing the aluminum foil and copper foil from folding and facilitating the normal coating of the aluminum foil and copper foil.

[0029] Reference Figure 2 and Figure 3As shown, bearings 55 are fixedly connected to the outer surfaces of the first threaded rod 51 and the second threaded rod 52. The outer surfaces of the bearings 55 are fixedly connected to the inner wall of the extension block 8. By setting the bearings 55, the friction between the first threaded rod 51 and the second threaded rod 52 and the extension block 8 can be reduced when rotating the first threaded rod 51 and the second threaded rod 52, thus making it easier to rotate the first threaded rod 51 and the second threaded rod 52. An operating block 56 is fixedly connected to the ends of the first threaded rod 51 and the second threaded rod 52 that are far apart from each other. The outer surface of the operating block 56 is provided with protrusions. By setting the operating block 56, rotating the operating block 56 can drive the threaded rod to rotate. At the same time, the protrusions on the outer surface of the operating block 56 can effectively increase the friction on the outer surface of the operating block 56, which has an anti-slip effect when rotating the operating block 56.

[0030] Reference Figure 2 and Figure 3 As shown, nuts 57 are provided on both sides of the screw hole block 53. The four nuts 57 are symmetrically threaded to the outer surfaces of the first threaded rod 51 and the second threaded rod 52, respectively. By providing two nuts 57 and rotating the two nuts 57, one side of the two nuts 57 abuts against the two sides of the screw hole block 53, which can provide auxiliary fixation between the two screw hole blocks 53 and the first threaded rod 51 and the second threaded rod 52, which helps to prevent the screw hole block 53 from easily shifting. Rubber plates 58 are provided on the side of the two limiting plates that are close to each other. One side of the rubber plate 58 is fixedly connected to one side of the limiting block 54. By providing the rubber plate 58, one side of the limiting plate can be attached to the side of the aluminum foil and copper foil, thereby providing a certain degree of protection for the aluminum foil and copper foil.

[0031] Reference Figure 2 and Figure 4 As shown, the positioning device 6 includes a positioning plate 61, which is located in the middle of the bottom of the base 7. A round rod 62 is symmetrically fixedly connected to the top of the base 7. A connecting block 63 is slidably connected to the outer surface of the round rod 62. One side of the two connecting blocks 63 is symmetrically fixedly connected to the two sides of the base 7. By setting the positioning plate 61, pushing the positioning plate 61 will cause the round rod 62 to slide on the inner wall of the connecting block 63 until the bottom of the positioning plate 61 abuts against the ground. This can increase the support area and friction between the coating equipment and the ground, which is beneficial to prevent the coating equipment from easily shifting or tipping over.

[0032] Reference Figure 4As shown, a circular hole block 64 is fixedly connected to one side of the connecting block 63. Two insertion holes 65 are opened on the outer surface of the circular rod 62. The same pin 66 is inserted into the inner wall of the circular hole block 64 and one of the insertion holes 65. By setting the pin 66, the positioning plate 61 can be fixed by inserting the pin 66 into the inner wall of the circular hole block 64 and the corresponding insertion hole 65. An auxiliary block 67 is fixedly connected to one end of the pin 66. A spring 68 is sleeved on the outer surface of the pin 66. One end of the spring 68 is fixedly connected to one side of the circular hole block 64, and the other end of the spring 68 is fixedly connected to one side of the auxiliary block 67. By setting the spring 68, the auxiliary block 67 connected to the pin 66 and the circular hole block 64 can be connected, which helps to prevent the pin 66 from easily detaching from the insertion hole 65 and the circular hole block 64 and being easily lost.

[0033] Working principle: When it is necessary to limit the movement of aluminum foil and copper foil, rotating the operating block 56 drives the first threaded rod 51 and the second threaded rod 52 to rotate. The first threaded rod 51 and the second threaded rod 52 will respectively drive a limiting block 54 connected to the screw hole block 53 to move until the rubber plate 58 on one side of the two limiting blocks 54 is about to abut against the two sides of the aluminum foil or gold foil. Then, rotating the two nuts 57 will cause one side of the two nuts 57 to abut against the two sides of the screw hole block 53. This can provide auxiliary fixation between the two screw hole blocks 53 and the first threaded rod 51 and the second threaded rod 52, which helps to prevent the screw hole blocks 53 from easily shifting. This can limit the movement of the aluminum foil or gold foil and help prevent the aluminum foil or gold foil from shifting. During the movement of the copper foil on the auxiliary roller 9, the copper foil shifts, thus preventing the aluminum foil and copper foil from folding and facilitating normal coating of the aluminum foil and copper foil. When it is necessary to position the coating equipment, pulling the auxiliary block 67 causes the pin 66 to disengage from the inner wall of the insertion hole 65, causing the spring 68 to deform. Then, the positioning plate 61 is pushed to drive the round rod 62 to slide on the inner wall of the connecting block 63 until the bottom of the positioning plate 61 abuts against the ground. The external force on the auxiliary block 67 is then removed, and the spring 68 will drive the pin 66 to reset, so that the pin 66 inserts into the inner wall of the insertion hole 65 and the round hole block 64. This increases the support area and friction between the coating equipment and the ground, which helps to prevent the coating equipment from easily shifting or tipping over.
