Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, and in particular to an adsorption roller and lithium battery manufacturing equipment. Background Art

[0002] During the coating process of lithium battery electrodes, a vacuum adsorption roller is usually used to pull them. In order to prevent foreign matter from entering the adsorption roller or the substrate from being caught on the surface of the adsorption roller during the working process, a cloth cover needs to be installed outside the adsorption roller, and the cloth cover needs to be cleaned and replaced regularly.

[0003] The existing vacuum adsorption roller generally comprises a hollow shaft reduction motor 1, an adsorption roller body 2, a clamping fixed block 6, a driving side wall plate 4 and a fixed side wall plate 5, as shown in FIG. Figure 1 As shown, the suction roller body 2 is located between the driving side wall panel 4 and the fixed side wall panel 5, and includes a roller shaft 2b and a roller 2a that is rotatably mounted on the outer periphery of the roller shaft 2b. The hollow shaft reduction motor 1 is fixed to the driving side wall panel 4 via a flange, and a transmission connection with the roller 2a is achieved by inserting the connecting shaft at one end of the roller 2a into its hollow shaft. The clamping and fixing block 3 is fixedly set on the fixed side wall panel 5, and one end of the roller shaft 2b is clamped to the fixed side wall panel 5 via the clamping and fixing block 3, and is connected to the vacuum source via a vacuum interface, and is connected to a vacuum pressure gauge 6 via another interface near the end. When replacing the cloth cover of the above-mentioned vacuum suction roller structure, since the vacuum pressure gauge 6 and the air pipe connected to the vacuum source will interfere with the threading of the cloth cover, it is necessary to disassemble and separate the hollow shaft reduction motor 1, flange, roller 2a and driving side wall panel 4 to achieve the replacement of the cloth cover. The disassembly and installation of the components are numerous and the process is cumbersome. In addition, since the adsorption roller is heavy, it is difficult for one person to support it. During the process of removing and replacing the cloth cover, the operator may be easily injured, causing safety accidents, or the operator may need to use supporting tools to assist in disassembly, further reducing the replacement efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0030] Please refer to Figures 2 to 4 An embodiment of the present invention provides an adsorption roller, comprising an adsorption roller body 10, a driving member, a flange 30, a driving side wall plate 40, a fixed side wall plate 50, a connecting assembly 60, and a supporting assembly 70. The driving member is a hollow shaft reduction motor 20.

[0031] The suction roller body 10 is located between the drive side wall panel 40 and the fixed side wall panel 50. The suction roller body 10 includes a roller shaft 13 and a roller 12 that is rotatably mounted on the outer periphery of the roller shaft 13. The outer periphery of the roller 12 is covered with a cloth sleeve. A connecting shaft 122 is provided at the first end of the roller 12. The first end of the roller 13 is closed, while the second end of the roller 13 is open. Two sealed bearings 123 are respectively located within the first and second ends of the roller 12. The two sealed bearings 123 are respectively mounted on the outer periphery of the roller shaft 13. The sealed bearings 123 are conventional structures. The sealed bearings 123 provide support for the rotation of the roller 12 and provide a sealing function to prevent external air from entering the interior of the roller 12.

[0032] The flange 30 is located between the hollow shaft reduction motor 20 and the driving side wall plate 30. One end of the flange 30 is installed in the through hole 42 of the driving side wall plate 40 through fasteners such as screws and is installed with a baffle 32 through fasteners such as screws, and the other end is installed to the hollow shaft reduction motor 20 through fasteners such as screws. The through hole 42 of the driving side wall plate 40, the through hole of the baffle 32 and the interior of the flange 30 form an installation channel, and the connecting shaft 122 partially passes through the installation channel and cooperates with the hollow output shaft 22 of the hollow shaft reduction motor 20, that is, the hollow shaft, so as to realize the transmission connection between the hollow shaft reduction motor 20 and the first end of the roller 12. The hollow shaft reduction motor 20 is used to drive the connecting shaft 122 to rotate through its output shaft 22, thereby driving the roller 12 to rotate relative to the roller shaft 13. Combined Figure 5As shown, a rotating bearing 33 is provided between the connecting shaft 122 and the inner circumference of the flange 30. The rotating bearing 33 is sleeved around the outer circumference of the connecting shaft 122 to provide support for the rotation of the connecting shaft 122. The outer circumference of the connecting shaft 122 has a connecting shaft step 122a, and an axial stop structure is provided on the outer circumference of the connecting shaft 122. The inner ring of the rotating bearing 33 is restrained between the axial stop structure and the connecting shaft step 122a. The inner circumference of the flange 30 has a flange step 30a, and the outer ring of the rotating bearing 33 is restrained between the flange step 30a and the stopper 32, thereby preventing the rotating bearing 33 from moving axially along the connecting shaft 122. The axial stop structure includes a bearing lock nut 34 sleeved around the outer circumference of the connecting shaft 122 and a bearing spacer 35. The bearing spacer 35 is sandwiched between the bearing lock nut 34 and the inner ring of the rotating bearing 33.

[0033] Combine Figure 6 and Figure 7 As shown, the connecting assembly 60 includes a connecting member 62 and a first linear bearing 63 .

[0034] The connecting member 62 is provided through the through hole 52 of the fixed side wall plate 50 and can move relative to the fixed side wall plate 50 toward or away from the suction roller body 10. The second end of the roller shaft 13 is detachably connected to the end of the connecting member 62 near the suction roller body 10, facilitating assembly and disassembly. Specifically, a mounting portion 132 is formed at the second end of the roller shaft 13, which is movably inserted into the end of the connecting member 62 near the suction roller body 10. The end of the connecting member 62 near the suction roller body 10 is provided with an arc-shaped notch, and a corresponding clamping member 622 is provided in the notch. The first end of the clamping member 622 is formed on the inner wall of the first end of the notch, and a first gap is defined between the second end of the clamping member 622 and the inner wall of the second end of the notch. A second gap is defined between the side of the clamping member 622 near the bottom of the notch and the bottom of the notch. A first mounting hole 6222 is defined on the outer surface of the second end of the clamping member 622. The first mounting hole 6222 extends to the second end of the clamping member 622. A second mounting hole 6223 is defined on the inner wall of the second end of the notch. The second mounting hole 6223 extends to the outer circumferential surface of the end of the connecting member 62 that is adjacent to the suction roller body 10. Fasteners, such as screws, are installed in the first and second mounting holes 6222 and 6223. Both the first and second mounting holes 6222 and 6223 are screw holes. The fasteners abut the outer circumferential surface of the mounting portion 132, thereby securing the mounting portion 132 to the end of the connecting member 62 that is adjacent to the suction roller body 10. The first and second gaps are provided to allow the clamping member 622 to deform to a certain extent when fasteners are installed in the first and second mounting holes 6222 and 6223.

[0035] The first end of the clamping member 622 is preferably integrally formed on the inner wall of the first end of the notch to facilitate manufacturing.

[0036] The outer circumference of the roller 12 is provided with a plurality of suction holes, evenly distributed along the outer circumference of the roller 12, and connected to the interior of the roller 12. The outer circumference of the roller shaft 13 is provided with a plurality of air holes, spaced apart along the axial direction of the roller shaft 13. Under the sealing action of the two sealed bearings 123, the air holes are connected to the interior of the roller 12 and the interior of the roller shaft 13, respectively. The number of suction holes and air holes can be adjusted according to actual conditions. The end of the connector 62, away from the suction roller body 10, is connected to a vacuum port 64. This port 64 is used to connect to a vacuum source (i.e., a vacuum pumping device). The vacuum port 64 communicates with the interior of the connector 62, which in turn communicates with the interior of the mounting portion 132. The mounting portion 132 communicates with the interior of the roller shaft 13 through an opening at the second end of the roller shaft 13. Thus, the vacuum port 64, the interior of the connector 62, the interior of the mounting portion 132, and the interior of the roller shaft 13 are sequentially connected. In actual application, the vacuum interface 64 is evacuated through a vacuum source, so that the adsorption hole can be evacuated through the inside of the connecting part 62, the inside of the mounting part 132, the inside of the roller shaft 13, the air hole, and the inside of the roller 12, so that the electrode passing thereon can be adsorbed through the adsorption hole, thereby increasing the friction between the electrode and the roller and avoiding wrinkles on the electrode.

[0037] One end of the connecting member 62 away from the adsorption roller body 10 is connected to a vacuum pressure gauge via a joint 65 . The vacuum pressure gauge is used to measure the pressure and vacuum degree of the gas in the connecting member 62 .

[0038] A sealing ring 133 is sleeved around the outer periphery of the mounting portion 132. The sealing ring 133 abuts against the inner wall of the end of the connector 62 proximal to the suction roller body 10, providing a seal. In this embodiment, an annular groove is defined on the outer periphery of the mounting portion 132, within which the sealing ring 133 is disposed. Two sealing rings 133 are provided, spaced apart along the axial direction of the mounting portion 132. The number of annular grooves corresponds to the number of sealing rings 133, also two. It is understood that the number of sealing rings 133 and annular grooves can be adjusted based on actual conditions.

[0039] The first linear bearing 63 is disposed within the through-hole 52 of the fixed sidewall plate 50. Part of the first linear bearing 63 extends from the side of the fixed sidewall plate 50 away from the suction roller body 10. The first linear bearing 63 is sleeved around the outer circumference of the connector 62. The first linear bearing 63 supports the movement of the connector 62 and ensures the radial position accuracy of the suction roller after assembly and disassembly. The end of the first linear bearing 63 away from the suction roller body 10 is connected to the side of the fixed sidewall plate 50 away from the suction roller body 10 via a connecting post 632 to secure the first linear bearing 63. Specifically, one end of the connecting post 632 is mounted in the mounting position on the end of the first linear bearing 63 away from the suction roller body 10, and the other end is mounted in the mounting position on the side of the fixed sidewall plate 50 away from the suction roller body 10. In this embodiment, there are four connecting posts 632, evenly distributed along the circumference. It is understood that the number of connecting posts 632 can be adjusted based on actual needs.

[0040] Combine Figure 6 and Figure 8 As shown, the support assembly 70 includes a mounting block 72 and a support block 73, which are arranged on a side of the fixed side wall plate 50 near the suction roller body 10. The second end of the roller shaft 13 is placed on the top of the support block 73, so that the second end of the roller shaft 13 can be supported by the support block 73. The support block 73 is connected to the mounting block 72 and can move up and down relative to the mounting block 72. When the support block 73 moves downward to a predetermined position, the support block 73 separates from the second end of the roller shaft 13, thereby revoking the support for the second end of the roller shaft 13. When the support block 73 moves upward to the initial position, the second end of the roller shaft 13 can be placed on the top of the support block 73, so that the second end of the roller shaft 13 can be supported by the support block 73.

[0041] In this embodiment, the top end of the support block 73 has a support position 732 , and the second end of the roller shaft 13 cooperates with the support position 732 . The support position 732 is arc-shaped.

[0042] In this embodiment, the support block 73 is connected to the mounting block 72. Specifically, the mounting block 72 has a screw hole, through which an adjustment screw 74 is provided. The adjustment screw 74 is preferably a trapezoidal screw, and the adjustment screw 74 is threadedly engaged with the screw hole. The head of the adjustment screw 74 is located below the mounting block 72 and is provided with a handle 742. The end of the adjustment screw 74 is located above the mounting block 72 and connected to the bottom end of the support block 73. Specifically, the bottom end of the support block 73 has a first insertion hole, and the end of the adjustment screw 74 is fixedly inserted into the first insertion hole. By rotating the handle 742, the adjustment screw 74 can be driven to rotate. Under the action of the screw hole, the rotation of the adjustment screw 74 can drive the support block 73 to move up and down.

[0043] The outer thread of the adjusting screw 74 is matched with a locking nut 75, and the locking nut 75 is located above the mounting block 72. By tightening the locking nut 75, the adjusting screw 74 can be locked and fixed on the mounting block 72 to prevent the adjusting screw 74 from rotating.

[0044] The mounting block 72 has a through hole, through which a guide post 76 is provided. One end of the guide post 76 is located below the mounting block 72, and the other end is located above the mounting block 72 and connected to the bottom end of the support block 73. Specifically, the bottom end of the support block 73 has a second plug hole 733, which extends to the top of the support block 73. The end of the guide post 76 located above the mounting block 72 is fixedly inserted into the second plug hole 733. The guide post 76 can move synchronously with the support block 73, and the guide post 76 plays a guiding role in the up and down movement of the support block 73. A second linear bearing 77 is provided in the through hole, and the second linear bearing 77 is sleeved on the outer circumference of the guide post 76 to provide support for the movement of the guide post 76. In this embodiment, there are two guide columns 76, and the adjusting screw 74 is located between the two guide columns 76. The number of through holes, second plug holes 733, and second linear bearings 77 corresponds to the number of guide columns 76, which is also two. It can be understood that the number of guide columns 76, through holes, second plug holes 733, and second linear bearings 77 can be set according to actual conditions.

[0045] Through the above structure, when the present invention actually needs to replace the new cloth cover, the old cloth cover on the outer periphery of the roller 12 is folded first to reduce the length of the old cloth cover. Figure 9 When the locking nut 75 is loosened and the adjusting screw 74 is turned, the support block 73 moves downward to the predetermined position, at which time a gap is formed between the support block 73 and the second end of the roller shaft 13; the folded old cloth cover is then passed through the gap between the support block 73 and the second end of the roller shaft 13 and moved to the outer periphery of the connecting member 62; the adjusting screw 74 is then turned and the locking nut 75 is tightened to move the support block 73 upward to the initial position, at which time the second end of the roller shaft 13 cooperates with the supporting position 732 of the support block 73, so that the second end of the roller shaft 13 can be supported by the support block 73; the fasteners in the first mounting hole 6222 and the second mounting hole 6223 are then removed; the connecting member 62 is then moved in a direction away from the suction roller body 10, so that the mounting portion 132 is separated from the end of the connecting member 62 close to the suction roller body 10 and there is a space, and the old cloth cover is removed from the connecting member 62 while the connecting member 62 is moved in a direction away from the suction roller body 10. Then place the folded new cloth cover 124 in the space between the mounting portion 132 and the end of the connecting member 62 close to the adsorption roller body 10, as shown in FIG. Figure 9Then move the connecting member 62 in the direction close to the adsorption roller body 10, so that the connecting member 62 passes through the new cloth cover 124 until the mounting portion 132 is inserted into the end of the connecting member 62 close to the adsorption roller body 10. At this time, the new cloth cover 124 is located at the outer periphery of the connecting member 62; then install the fasteners in the first mounting hole 6222 and the second mounting hole 6223, as shown. Figure 10 Then loosen the locking nut 75 and rotate the adjusting screw 74 to move the support block 73 downward to a predetermined position, at which time there is a gap between the support block 73 and the second end of the roller shaft 13, as shown. Figure 11 As shown; then press the new cloth cover 124 Figure 11 The direction of the arrow shown passes through the gap between the support block 73 and the second end of the roller shaft 13 and moves to the outer periphery of the roller 12. Then, the adjusting screw 74 is rotated and the locking nut 75 is tightened to move the support block 73 upward to the initial position. At this time, the second end of the roller shaft 13 and the support position 732 of the support block 73 are supported. The new cloth cover 124 is then unfolded so that the new cloth cover 124 covers the outer periphery of the roller 12. In this way, the new cloth cover 124 is replaced. The present invention provides a connector 62 and a support block 73. Since the vacuum port 64 and the joint 65 are both provided on the connector 62, there is no obstacle on the second end side of the roller shaft 13 that would hinder the cloth cover from being inserted, so the cloth cover can be replaced from this side. When a new cloth cover 124 is needed, only the end of the connector 62 closest to the suction roller body 10 needs to be disconnected from the second end of the roller shaft 13. No other components need to be disassembled, resulting in fewer disassembly parts and less time and effort. Furthermore, the vertically movable support block 73 allows for downward movement when a gap is required between the support block 73 and the second end of the roller shaft 13 for the cloth cover to pass through. When the support block 73 is needed to support the second end of the roller shaft 13, the support block 73 can be moved upward. This eliminates the need for external support tools, making operation simple, reducing equipment downtime, and improving production efficiency. Furthermore, the support block eliminates safety hazards during cloth cover removal and replacement. Furthermore, the connector 62 can slide axially along the roller shaft 13 to separate from the roller shaft 13, providing clearance for cloth cover removal and installation. This eliminates the need to remove the connector 62 from the fixed sidewall panel 50, ensuring consistent installation accuracy before and after cloth cover replacement. This eliminates the need for subsequent precision adjustments after cloth cover replacement, further improving replacement efficiency.
