Description

Technical Field

[0001] This application relates to the field of lithium battery electrode production technology, and in particular to winding and unwinding safety railings and winding and unwinding equipment. Background Technology

[0002] In the production process of lithium battery electrodes, the electrodes are successively manufactured through processes such as coating, rolling, slitting, and sheet forming. Each of these processes requires a winding / unwinding mechanism to wind or unwind the electrode rolls. Existing winding / unwinding mechanisms mostly employ dual-axis turrets for automatic winding and unwinding of the electrode rolls. When using a dual-axis turret for winding / unwinding, the heavy weight of the rolls and their high-speed rotation pose certain safety hazards.

[0003] In related technologies, safety railings are installed around the turret to protect the turret equipment. However, this protective facility can only isolate the turret equipment from the external environment, but cannot isolate the winding and unwinding areas and loading and unloading areas inside the turret equipment. As a result, hazards in the winding and unwinding areas, such as the rotation of the coils and the movement of the clamps, are not isolated, posing a safety hazard to the workers in the loading and unloading areas. Utility Model Content

[0004] To solve or partially solve the problems existing in the related technologies, this application provides a winding and unwinding safety guardrail and winding and unwinding equipment, which can completely isolate the winding and unwinding area and the loading and unloading area of ​​the winding and unwinding equipment without hindering the rotation and material changing operation of the winding and unwinding equipment.

[0005] The first aspect of this application provides a safety guardrail for winding and unwinding rolls, comprising:

[0006] A rotating guardrail is provided between the first working area and the second working area of ​​the winding and unwinding device, and can rotate with the winding and unwinding device between the first working area and the second working area.

[0007] A lifting guardrail is provided relative to a rotating guardrail, and the lifting guardrail can move towards or away from the rotating guardrail; when the lifting guardrail moves away from the rotating guardrail, it can move to a first preset position to provide clearance space for the winding and unwinding device to rotate; and when the lifting guardrail moves towards the rotating guardrail, it can move to a second preset position to eliminate the clearance space.

[0008] As an optional embodiment, the roll-up safety barrier further includes a positioning mechanism, which is used to determine whether the lifting barrier has moved to the first preset position and / or the second preset position.

[0009] As an optional embodiment, the positioning mechanism includes a trigger and a sensor, one of which remains stationary relative to the lifting guardrail and is located at a first preset position and / or a second preset position, and the other of which is fixed to the lifting guardrail and can move with the lifting guardrail; and when the lifting guardrail moves to the first preset position and / or the second preset position, the trigger activates the sensor.

[0010] As an optional embodiment, the roll-up safety barrier further includes at least one buffer member, which is used to buffer the movement of the lifting barrier when the lifting barrier moves to the first preset position and / or the second preset position.

[0011] As an optional embodiment, the roll-up safety barrier further includes a drive mechanism, the drive mechanism comprising:

[0012] A drive rod, wherein the drive rod is vertically arranged and the drive end of the drive rod is connected to the lifting guardrail;

[0013] A driver, which remains stationary relative to the lifting guardrail, is connected to the end of the drive rod away from the lifting guardrail and is used to drive the drive rod to extend or retract, thereby causing the lifting guardrail to move up and down.

[0014] As an optional embodiment, the rotating guardrail has a first region and a second region, the first region and the second region respectively corresponding to the interference region and the non-interference region of the winding and unwinding device; the winding and unwinding safety guardrail also includes a fixed guardrail, the lifting guardrail is disposed relative to the first region, the fixed guardrail is disposed relative to the second region on at least one side of the lifting guardrail, and the lifting guardrail can move along the height direction of the fixed guardrail.

[0015] As an optional embodiment, the roll-up safety barrier further includes a guide mechanism, which is disposed on the movable contact surface between the fixed barrier and the lifting barrier, and is used to guide the lifting barrier to move up and down on the fixed barrier.

[0016] As an optional embodiment, the guiding mechanism includes:

[0017] A vertically arranged guide post is located on the side of the fixed guardrail opposite to the lifting guardrail;

[0018] A guide wheel is connected to one side of the lifting guardrail opposite the guide post, and the lifting guardrail rolls along the height direction of the guide post via the guide wheel.

[0019] As an optional embodiment, the roll-up safety guardrail further includes a reset member, which is disposed on the movable contact surface between the fixed guardrail and the lifting guardrail. The reset member is stretched when the lifting guardrail descends and exerts an upward pulling force on the lifting guardrail when the lifting guardrail rises.

[0020] A second aspect of this application provides a winding and unwinding device, comprising:

[0021] Base;

[0022] A take-up and unwinding device, rotatably mounted on the base, for switching between a first working area and a second working area; and,

[0023] The aforementioned winding and unwinding safety guardrail has a rotating guardrail located between the first and second working areas of the winding and unwinding device, and can rotate with the winding and unwinding device between the first and second working areas; the bottom of the base has a lifting channel relative to the rotating guardrail, and the lifting guardrail is vertically arranged below the rotating guardrail relative to the lifting channel, and can move up and down within the lifting channel along its own height direction.

[0024] The technical solution provided in this application may include the following beneficial results:

[0025] During the rotational switching between the first and second working areas of the unwinding and take-up device, the material roll on the device may interfere with the lifting guardrail when it rotates downwards, hindering its continued rotation. To avoid affecting the material changing operation of the unwinding and take-up device, this application provides a lifting guardrail that can move along its own height towards or away from the rotating guardrail. Specifically, when the material roll on the unwinding and take-up device interferes with the lifting guardrail, the lifting guardrail can move away from the rotating guardrail to a first preset position, providing clearance for the unwinding and take-up device to continue rotating; and when the unwinding and take-up device is in position, the lifting guardrail can move towards the rotating guardrail to a second preset position, eliminating the clearance and re-isolating the first and second working areas of the unwinding and take-up device. Therefore, the safety guardrail of this application not only provides comprehensive protection for the unwinding and take-up device but also does not affect its normal operation.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In related technologies, safety railings are installed around the turret to protect the turret equipment. However, this protective facility can only isolate the turret equipment from the external environment, but cannot isolate the winding and unwinding areas and loading and unloading areas inside the turret equipment. As a result, hazards in the winding and unwinding areas, such as the rotation of the coils and the movement of the clamps, are not isolated, posing a safety hazard to the workers in the loading and unloading areas.

[0044] To address the aforementioned issues, this application provides a winding and unwinding safety guardrail that can completely isolate the winding and unwinding area and the loading and unloading area of ​​the winding and unwinding equipment without hindering the rotating and material-changing actions of the winding and unwinding equipment.

[0045] See Figures 1 to 4 This application provides a winding and unwinding safety barrier, including a rotating barrier 1 and a lifting barrier 2. The rotating barrier 1 is disposed between a first working area 90 and a second working area 91 of the winding and unwinding device 9, and can rotate with the winding and unwinding device 9 between the first working area 90 and the second working area 91; the lifting barrier 2 is vertically disposed below the rotating barrier 1, and the lifting barrier 2 can move towards or away from the rotating barrier 1 along its own height direction; when the lifting barrier 2 moves away from the rotating barrier 1, the lifting barrier 2 can move to a first preset position 21 to leave a clearance space 20 for the winding and unwinding device 9 to rotate; and when the lifting barrier 2 moves towards the rotating barrier 1, the lifting barrier 2 can move to a second preset position 22 to eliminate the clearance space 20.

[0046] In the embodiments of this application, see Figure 3 and Figure 4 The winding / unwinding device 9 can be a dual-axis turret. The first working area 90 of the winding / unwinding device 9 can be referred to as the winding / unwinding zone, where the winding / unwinding of the material roll on the winding / unwinding device 9 is performed. The second working area 91 of the winding / unwinding device 9 can be referred to as the loading / unloading zone, where the loading / unloading of the material roll on the rotating shaft of the winding / unwinding device 9 is performed. The winding / unwinding device 9 achieves winding / unwinding and loading / unloading of the material roll by rotating between the first working area 90 and the second working area 91.

[0047] In this embodiment, the first preset position 21 can refer to the target position where the lifting guardrail 2 descends. When the lifting guardrail 2 descends to the first preset position 21, the second preset position 22 can refer to the target position where the lifting guardrail 2 rises. The rotating guardrail 1 is positioned above the winding and unwinding device 9 to protect the first working area 90 and the second working area 91 above the winding and unwinding device 9. The lifting guardrail 2 is positioned below the winding and unwinding device 9 to protect the first working area 90 and the second working area 91 below the winding and unwinding device 9. The rotating guardrail 1 and the lifting guardrail 2 together form a safety guardrail, isolating the entire first working area 90 and the second working area 91 of the winding and unwinding device 9, thus achieving comprehensive protection for the winding and unwinding device 9. However, during the rotational switching between the first working area 90 and the second working area 91, when the material roll on the winding and unwinding device 9 rotates to the lower position, it will interfere with the lifting guardrail 2, hindering the material roll from continuing to rotate. In order not to affect the rotational material changing operation of the winding and unwinding device 9, this embodiment of the application sets the lifting guardrail 2 to move along its own height direction towards or away from the rotating guardrail 1. Specifically, when the material roll on the take-up / unwinding device 9 interferes with the lifting guardrail 2, the lifting guardrail 2 can move away from the rotating guardrail 1 and move to a first preset position 21 to leave a clearance space 20 for the take-up / unwinding device 9 to rotate, allowing the take-up / unwinding device 9 to continue rotating; and when the take-up / unwinding device 9 is in position, the lifting guardrail 2 can move towards the rotating guardrail 1 and move to a second preset position 22 to eliminate the clearance space 20 and re-isolate the first working area 90 and the second working area 91 of the take-up / unwinding device 9. Therefore, the safety guardrail of this embodiment can not only fully protect the take-up / unwinding device 9, but also does not affect the normal operation of the take-up / unwinding device 9.

[0048] As an optional embodiment, see Figure 5 and Figure 6 The roll-up safety guardrail also includes a positioning mechanism 3, which is used to determine whether the lifting guardrail 2 has moved to the first preset position 21 and / or the second preset position 22.

[0049] In this embodiment, the positioning mechanism 3 is used to automatically detect the movement of the lifting guardrail 2 into position, thereby improving the automated protection of the safety guardrail. Furthermore, the positioning mechanism 3 can also form a closed-loop detection system with the winding and unwinding device 9. For example, when the positioning mechanism 3 locates the lifting guardrail 2 at the first preset position 21, it can control the winding and unwinding device 9 to rotate and switch working areas; when the positioning mechanism 3 locates the lifting guardrail 2 at the second preset position 22, it can control the rotation of the material roll on the winding and unwinding device 9 to protect against hazards.

[0050] As a preferred embodiment, see Figure 7 and Figure 8The positioning mechanism 3 includes a trigger 30 and a sensor 31. One of the trigger 30 and the sensor 31 remains stationary relative to the lifting guardrail 2 and is located at a first preset position 21 and / or a second preset position 22. The other of the trigger 30 and the sensor 31 is fixed to the lifting guardrail 2 and can move with the lifting guardrail 2. When the lifting guardrail 2 moves to the first preset position 21 and / or the second preset position 22, the trigger 30 triggers the sensor 31.

[0051] In this embodiment, the positioning mechanism 3 may include two triggers 30 and one sensor 31. The two triggers 30 and the sensor 31 detect whether the lifting guardrail 2 has moved to a first preset position 21 and a second preset position 22. For example, one sensor 31 may remain stationary relative to the lifting guardrail 2, such as being mounted on the base 12 of the winding / unwinding equipment. The sensor 31 remains stationary during the movement of the lifting guardrail 2. The two triggers 30 are respectively located at the top and bottom of the lifting guardrail 2. When the lifting guardrail 2 descends to the first preset position 21, the trigger 30 triggers one of the sensors 31, causing the sensor 31 to receive a signal. Based on this signal, it is determined that the lifting guardrail 2 has descended to the first preset position 21, and the lifting guardrail 2 can be controlled to stop descending. When the lifting guardrail 2 rises to the second preset position 22, the trigger 30 triggers the other sensor 31, causing the sensor 31 to receive a signal. Based on this signal, it is determined that the lifting guardrail 2 has risen to the second preset position 22, and the lifting guardrail 2 can be controlled to stop rising.

[0052] In this embodiment of the application, the positioning mechanism 3 may also include two sets of triggers 30 and sensors 31, see [link to relevant documentation]. Figure 7 , Figure 7 A set of triggers 30 and sensors 31 are used to detect whether the lifting guardrail 2 has risen to the second preset position 22. The triggers 30 are located at the bottom of the lifting guardrail 2, and the sensors 31 remain stationary relative to the lifting guardrail 2, for example, they can be located on the base 12 of the winding and unwinding equipment, and are located at the second preset position 22. When the lifting guardrail 2 rises to the second preset position 22, the triggers 30 trigger the sensors 31, causing the sensors 31 to receive a signal. Based on this signal, it is determined that the lifting guardrail 2 has risen to the second preset position 22, and the lifting guardrail 2 can be controlled to stop rising.

[0053] See Figure 8 , Figure 8Another set of triggers 30 and sensors 31 are used to detect whether the lifting guardrail 2 has descended to the first preset position 21. The triggers 30 are located at the top of the lifting guardrail 2, and the sensors 31 remain stationary relative to the lifting guardrail 2, for example, they can be located on the base 12 of the winding and unwinding equipment, and at the first preset position 21. When the lifting guardrail 2 descends to the first preset position 21, the triggers 30 trigger one of the sensors 31, causing the sensor 31 to receive a signal. Based on this signal, it is determined that the lifting guardrail 2 has descended to the first preset position 21, and the lifting guardrail 2 can be controlled to stop descending.

[0054] As an optional embodiment, see Figure 7 and Figure 8 The roll-up safety barrier also includes at least one buffer 4, which is used to buffer the movement of the lifting barrier 2 when it moves to the first preset position 21 and / or the second preset position 22.

[0055] In this embodiment of the application, the buffer 4 can be configured as two, see [reference]. Figure 7 One of the buffer components 4 can be positioned downwards. When the lifting guardrail 2 rises to the second preset position 22, the buffer component 4 abuts against the lower part of the lifting guardrail 2 to cushion its upward movement. See also Figure 8 Another buffer 4 can be positioned upwards. When the lifting guardrail 2 descends to the first preset position 21, the buffer 4 abuts against the upper part of the lifting guardrail 2, buffering the downward movement of the lifting guardrail 2. The buffer 4 can be made of rubber material.

[0056] As an optional embodiment, see Figure 1 and Figure 2 ,as well as Figure 9 The roll-up safety barrier also includes a drive mechanism 5, which includes a drive rod 50 and a driver 51. The drive rod 50 is vertically arranged and its drive end is connected to the lifting barrier 2. The driver 51 remains stationary relative to the lifting barrier 2 and is connected to the end of the drive rod 50 away from the lifting barrier 2. The driver 51 is used to drive the drive rod 50 to extend or retract, thereby driving the lifting barrier 2 to move up and down.

[0057] In this embodiment, the driver 51 remains stationary relative to the lifting guardrail 2, for example, it can be mounted on the base 12 of the winding and unwinding equipment.

[0058] In this embodiment, the driver 51 and the drive rod 50 can be a combination of a motor and a lead screw, or a combination of a cylinder / hydraulic cylinder and a piston rod.

[0059] As an optional embodiment, see Figure 1 and Figure 2The rotating guardrail 1 has a first region 10 and a second region 11, which correspond to the interference region 92 and the non-interference region 93 of the winding and unwinding device 9, respectively; see also Figure 5 and Figure 6 The roll-up safety barrier also includes a fixed barrier 6, a lifting barrier 2 is set relative to the first area 10, the fixed barrier 6 is set relative to the second area 11 on at least one side of the lifting barrier 2, and the lifting barrier 2 can move along the height direction of the fixed barrier 6.

[0060] In the embodiments of this application, see Figure 1 and Figure 2 The interference region 92 of the winding and unwinding device 9 refers to the area where the feed roll of the winding and unwinding device overlaps with the area below it when the winding and unwinding device rotates. The non-interference region 93 refers to the area where the feed roll of the winding and unwinding device does not overlap with the area below it when the winding and unwinding device rotates. The first region 10 of the rotating guardrail 1 corresponds to the interference region 92 and is used to isolate and protect the interference region 92 of the winding and unwinding device 9. The second region 11 of the rotating guardrail 1 corresponds to the non-interference region 93 and is used to isolate and protect the non-interference region 93 of the winding and unwinding device 9.

[0061] This embodiment of the application provides zoned protection for the take-up and unwinding device 9. A lifting guardrail 2 is installed in the interference area 92, and a fixed guardrail 6 is installed in the non-interference area 93. The fixed guardrail 6 remains stationary relative to the lifting guardrail 2, for example, it can be installed on the base 12 of the take-up and unwinding device. The fixed guardrail 6 provides protection and fixation during the lifting and lowering of the lifting guardrail 2. The downward movement of the lifting guardrail 2 avoids interference with the rotational operation of the take-up and unwinding device 9. Simultaneously, the upward movement of the lifting guardrail 2, together with the fixed guardrail 6, forms isolation and protection for the area below the take-up and unwinding device 9. Together with the rotating guardrail 1, it forms isolation and protection for the entire area of ​​the take-up and unwinding device 9.

[0062] As a preferred embodiment, see Figure 9 The roll-up safety guardrail also includes a guide mechanism 7, which is located on the movable contact surface between the fixed guardrail 6 and the lifting guardrail 2, and is used to guide the lifting guardrail 2 to move up and down on the fixed guardrail 6.

[0063] In this embodiment, a guide mechanism 7 is provided to guide the lifting guardrail 2 to move up and down on the fixed guardrail 6, so as to prevent the lifting guardrail 2 from getting stuck or moving unevenly.

[0064] As a preferred embodiment, see Figure 9 The guiding mechanism 7 includes a vertically arranged guide post 70 and a guide wheel 71. The guide post 70 is located on the side of the fixed guardrail 6 opposite to the lifting guardrail 2. The guide wheel 71 is connected to the side of the lifting guardrail 2 opposite to the guide post 70, and the lifting guardrail 2 rolls along the height direction of the guide post 70 via the guide wheel 71.

[0065] In this embodiment, the guide mechanism 7 includes a guide post 70 and a guide wheel 71. The guide post 70 can have a track groove, and the guide wheel 71 rolls along the track groove, reducing the friction between the lifting guardrail 2 and the guide post 70 and improving the lifting efficiency of the lifting guardrail 2.

[0066] As a preferred embodiment, see Figure 9 The roll-up safety guardrail also includes a reset member 8, which is located on the movable contact surface between the fixed guardrail 6 and the lifting guardrail 2. The reset member 8 is stretched when the lifting guardrail 2 descends and exerts an upward pulling force on the lifting guardrail 2 when the lifting guardrail 2 rises.

[0067] In this embodiment, the reset member 8 can be a tension spring. When the lifting guardrail 2 descends, the tension spring is stretched and undergoes elastic deformation. When the lifting guardrail 2 rises, the tension spring restores its elasticity and exerts an upward pulling force on the lifting guardrail 2. Even if the drive mechanism 5 fails to work, the reset member 8 can pull the lifting guardrail 2 back through its elastic restoring force, which greatly ensures the safety of production and the reliability of the mechanism.

[0068] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a winding and unwinding device and corresponding embodiments.

[0069] This application embodiment also provides a winding and unwinding device, including a base 12, a winding and unwinding device 9, and the aforementioned winding and unwinding safety guardrail. The winding and unwinding device 9 is rotatably mounted on the base 12 to switch between a first working area 90 and a second working area 91. The rotating guardrail 1 is located between the first working area 90 and the second working area 91 of the winding and unwinding device 9, and can rotate with the winding and unwinding device 9 between the first working area 90 and the second working area 91. A lifting channel (not shown in the figure) is provided at the bottom of the base 12 relative to the rotating guardrail 1. The lifting guardrail 2 is vertically mounted below the rotating guardrail 1 relative to the lifting channel, and can move up and down within the lifting channel along its own height direction.

[0070] In this embodiment, due to the limited space below the winding and unwinding device 9, a lifting channel is provided at the bottom of the base 12. This allows for a larger lifting space for the lifting guardrail 2 without significant modifications to the equipment, thereby increasing the clearance space 20 and providing more room for the winding and unwinding device 9 to rotate. When the winding and unwinding device 9 needs to rotate to switch working areas, the lifting guardrail 2 descends within the lifting channel to create clearance space 20, and the winding and unwinding device 9 then rotates. After the winding and unwinding device 9 has rotated to its correct position, the lifting guardrail 2 rises within the lifting channel to eliminate clearance space 20, forming a complete safety guardrail together with the rotating guardrail 1. This provides comprehensive protection for the winding and unwinding device 9 without affecting its winding and unwinding operations.
