DETAILED DESCRIPTION

[0024] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] In the description of the present application, it should be pointed out that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application.

[0027] Referring to Figures 1 to 2 The present application discloses a diaphragm storage device, comprising a cabinet body 10, a support 20 and a driving assembly, the cabinet body 10 has a storage cavity 11 and a openable and closable cabinet door, a transmission shaft 33 is provided on the cabinet body 10, the transmission shaft 33 drives the cabinet door to rotate when rotating, and the cabinet body 10 is detachably connected with the support 20.

[0028] In addition, the driving assembly comprises a driving mechanism 30 and a transmission mechanism, the transmission mechanism comprises a driving wheel 31 and a driven wheel 32, the driving mechanism 30 and the driving wheel 31 are installed on the support 20, the driving mechanism 30 is used to drive the driving wheel 31 to rotate, the driven wheel 32 is connected with the transmission shaft 33, and is engagedly connected with the driving wheel 31 after the cabinet body 10 is connected with the support 20.

[0029] On the basis of the above structure, during assembly, the cabinet body 10 can be directly connected with the cabinet body 10 through the transmission shaft 33, so that the cabinet door rotates with the transmission shaft 33, and opens or closes the storage cavity 11 in the rotating process; or the cabinet door is connected with the cabinet body 10 through the rotating shaft 121, and then the rotating shaft 121 is connected with the transmission shaft 33 through the shaft coupling 14, so that the transmission shaft 33 rotates to drive the rotating shaft 121 to rotate, which can also make the cabinet door open and close the storage cavity 11 in the rotating process; during use, the cabinet body 10 is supported by the support 20, and when the cabinet body 10 is connected with the support 20, the driven wheel 32 connected with the transmission shaft 33 is meshed and connected with the driving wheel 31, so that when the driving mechanism 30 drives the driving wheel 31 to rotate, the driven wheel 32 also rotates to drive the transmission shaft 33 to rotate synchronously. At this time, the cabinet door opens or closes the storage cavity 11 in the rotating process of the transmission shaft 33, realizing automatic opening and closing of the cabinet door.

[0030] Specifically, the diaphragm buffer device in this embodiment is applied to the lamination equipment in the lithium battery industry. During use, the diaphragm 40 is stored in the storage cavity in the cabinet body 10, and the support 20 is arranged at the lamination position. Then the cabinet body 10 is transported to the support 20 by a guide vehicle or a cart, and the cabinet body 10 is installed on the support 20. During assembly, the driven wheel 32 on the transmission shaft 33 is aligned with the driving wheel 31, and then meshed and connected. In this way, during the lamination production process, the diaphragm 40 needs to be taken out of the cabinet body 10. Only by starting the driving mechanism 30 to drive the driving wheel 31 to rotate can the driven wheel 32 and the transmission shaft 33 be driven to rotate synchronously, so that the cabinet door can be automatically opened and closed during the lamination production process. Then the diaphragm 40 in the storage cavity 11 is clamped out by a mechanical arm. Then the driving mechanism 30 drives the driving wheel 31 to rotate, so that the cabinet door is automatically closed. During the whole material taking process, the worker does not need to go to the support 20 site personally, but can flexibly control the cabinet door according to the production progress and demand, which is convenient for overall arrangement of the production process, reduces the labor intensity to a certain extent, and improves the automation degree of production because the whole process does not need manual intervention.

[0031] Especially in some production scenes that need to frequently take and place the diaphragm 40, the driving mechanism 30 can quickly realize the opening and closing of the cabinet door, which can effectively reduce the waiting time of each operation, thereby improving the overall production efficiency.

[0032] More specifically, when the diaphragm 40 in the cabinet body 10 is used up, the diaphragm 40 needs to be refilled. Since the cabinet body 10 and the support 20 can be disassembled, the cabinet body 10 only needs to be taken off from the support 20, and then the cabinet body 10 is transported to the specified position by the automatic guide vehicle to refill the diaphragm 40. When the diaphragm 40 is refilled, the cabinet body 10 is moved to the support 20 again to start the next cycle of work.

[0033] In addition, since the driving mechanism 30 generally contains more electrical components, if the driving mechanism 30 is installed on the cabinet 10, the electrical components on the driving mechanism 30 can be easily damaged or loose during the transportation of the cabinet 10, leading to frequent loose contact of the electrical coupler, poor contact, high failure rate and other phenomena, and the driving mechanism 30 is also easy to generate static electricity during the operation on the diaphragm 40 cabinet, which affects the quality of the diaphragm 40. Therefore, in the embodiment, the driving mechanism 30 is installed on the support 20, so that the driving mechanism 30 is physically isolated from the cabinet 10. Even if the electrical components on the driving mechanism 30 have a leakage fault, it is difficult for the current to conduct to the cabinet 10, thereby ensuring the safety of the cabinet 10 and the surrounding operators, avoiding electric shock accidents caused by the cabinet 10 being electrified due to motor leakage, and indirectly improving the safety in the production process.

[0034] It should be noted that the driving mechanism 30 in the embodiment is a driving motor, which can be a step motor, a DC motor or an AC motor, etc. During assembly, the motor shaft of the driving motor can be coupled with the driving wheel 31 to drive the driving wheel 31 to rotate. The driving wheel 31 and the driven wheel 32 can be two gears that mesh with each other.

[0035] In addition, in the embodiment, the cabinet door can be a roller shutter door or a common swing door. The cabinet door is connected to the cabinet 10 through the rotating shaft 121 or the transmission shaft 33 by rotating. When the roller shutter door is used, the roller shutter door is folded or unfolded during rotation to open or close the storage cavity 11. When the swing door is used, the swing door moves away from or approaches the opening of the storage cavity 11 during rotation, which can also open or close the storage cavity 11.

[0036] Further, the top of the support 20 is provided with a plurality of guide blocks 21, which are distributed on both sides of the support 20 at intervals. The guide blocks 21 are provided with guide inclined surfaces 211, which are in sliding cooperation with the edges of the cabinet 10 when the cabinet 10 approaches the support 20, so as to guide the driven wheel 32 to mesh with the driving wheel 31.

[0037] Specifically, during assembly, the plurality of guide blocks 21 are uniformly distributed on both sides of the support 20 at intervals. When the cabinet 10 approaches the support 20, the guide inclined surface 211 first contacts the edge of the cabinet 10. Since the guide inclined surface 211 is inclined, a horizontal component force is generated during the sliding of the edge of the cabinet 10 along the guide inclined surface 211. This component force gradually adjusts the position of the cabinet 10 relative to the support 20, like a "guide rail", so that the cabinet 10 gradually moves in the direction that can achieve the correct meshing of the driven wheel 32 and the driving wheel 31 during the approach to the support 20, so that the driven wheel 32 can be more accurately meshed with the driving wheel 31 after the connection of the cabinet 10 and the support 20.

[0038] More specifically, the guide block 21 is made of insulating material, so that in the working environment of the bracket 20 and the cabinet 10, if there is a leakage of electrical equipment, the guide block 21 as an insulating material can prevent the conduction of current. For example, when the motor or other charged equipment near the bracket 20 leaks, the current will not conduct through the guide block 21 to the cabinet 10 or the operator's body, avoiding the occurrence of electric shock accidents and improving the safety during use.

[0039] It should be noted that the guide block 21 in the embodiment can be made of polyurethane, polyphenyl ether or phenolic plastic insulating material.

[0040] As preferred, the guide block 21 in the embodiment is made of polyurethane, which has good elastic deformation ability. During the docking process of the cabinet 10 and the bracket 20, even if there is a certain impact force or a large positional deviation between the docking part of the cabinet 10 or the bracket 20 and the guide block 21, the polyurethane guide block 21 can absorb part of the energy through elastic deformation, and adjust its shape through its own deformation to better fit the docking part. This elastic deformation will not cause damage to the cabinet 10 or the bracket 20, reducing the risk of damage during the docking process of the cabinet 10 and the bracket 20.

[0041] Further, the driving wheel 31 and the driven wheel 32 are made of insulating material, which has very high resistance and is difficult for current to pass through. When the driving mechanism 30 (such as a driving motor) is running, even if the driving mechanism 30 leaks or has an electrical fault to make the motor shell charged, the current is not easy to pass through the driving wheel 31 to the driven wheel 32 and then to the cabinet 10, thereby reducing the probability of the cabinet 10 being charged, preventing electric shock when a person touches the cabinet 10, and improving the safety of the equipment. At the same time, it can also reduce the risk of static electricity generated during the operation of the driving mechanism 30 being transferred to the cabinet 10, and reduce the probability of affecting the quality of the diaphragm 40 in the storage cavity 11 due to static electricity being transferred to the cabinet 10.

[0042] It should be noted that the driving wheel 31 and the driven wheel 32 in the embodiment can also be made of polyurethane, polyphenyl ether or phenolic plastic insulating material.

[0043] Further, the cabinet 10 is provided with a connecting piece 13, the connecting piece 13 is provided with a through hole, and the transmission shaft 33 is arranged in the through hole in the first direction.

[0044] Specifically, the connecting piece 13 protrudes from the periphery of the cabinet 10 and is arranged in the first direction (such as the direction shown in the figure), that is, the vertical direction of the cabinet. During assembly, the transmission shaft 33 is arranged in the through hole in a vertical state, so that the transmission shaft 33 is more stable in connection with the cabinet 10, and then the transmission shaft 33 is connected with the driven shaft or other structures. Figure 1 ​

[0045] Further, the top of the cabinet 10 is provided with a rotating shaft 121, which extends along the length direction of the cabinet 10 and is coupled with the transmission shaft 33 through the coupling 14. The rotating shaft 121 is used to rotate with the transmission shaft 33. The cabinet door includes the curtain 12, which is wound on the rotating shaft 121 and is wound or unfolded when the rotating shaft 121 rotates, so as to open or close the storage cavity 11.

[0046] Specifically, the rotating shaft 121 extends along the second direction (for example, the transverse direction of the cabinet), and the transmission shaft 33 is coupled with the rotating shaft 121 through the coupling 14. The direct transmission of power is realized, so that the rotating power of the transmission shaft 33 can be effectively transmitted to the rotating shaft 121, and the power loss is reduced. In this way, the curtain 12 is wound on the rotating shaft 121, and when the rotating shaft 121 rotates with the transmission shaft 33, the curtain 12 can be wound or unfolded, so as to automatically open or close the storage cavity 11. Figure 1

[0047] By arranging the rotating shaft 121 on the top of the cabinet 10, the space on the top of the cabinet 10 is fully utilized, so that the curtain (the curtain 12) is not easy to interfere with other structures on the support 20 during winding and unfolding, and the smooth opening and closing action of the curtain is ensured.

[0048] More specifically, the bottom of the cabinet 10 is also provided with a laser sensor, which is arranged opposite to the curtain 12. In this way, the position of the curtain 12 can be monitored in real time by the laser sensor. During the opening or closing of the curtain 12, the laser sensor can accurately perceive the position of the curtain 12 by emitting and receiving laser signals, and then the laser sensor transmits the received position information to the control system in the background. According to the position information of the curtain 12 provided by the laser sensor, the system can better coordinate the working order between the curtain door and other equipment (such as a mechanical arm, a carrying robot or a conveying device, etc.). For example, when the mechanical arm completes the task of taking and placing the diaphragm 40 and leaves the cabinet 10, the control system can control the curtain door to close in time according to the feedback of the laser sensor, so as to realize seamless connection of the entire automatic process.

[0049] It should be noted that the laser sensor can be a laser distance sensor.

[0050] Further, the diaphragm buffer device in the embodiment further includes an insulating pad, which is arranged between the cabinet 10 and the support 20. In this way, when the electrical equipment on the support 20 has a leakage, the insulating pad can effectively prevent the current from being conducted from the support 20 to the cabinet 10, prevent the cabinet 10 from being electrified, and thus avoid the danger of electric shock of the operator, and the use process is safer.

[0051] ​Further, the ejecting assembly includes a pushing rod and a pushing plate, the pushing plate is connected with the pushing rod and extends out of the storage cavity 11 when the pushing rod rotates, and the driving mechanism 30 is used to drive the pushing rod to rotate.

[0052] Specifically, during assembly, the diaphragm 40 is placed on the pushing plate, then a driving motor is repositioned on the support 20, and then the motor shaft of the driving motor is connected with the pushing rod through the coupling 14 to drive the pushing rod to rotate and push the pushing plate out of the storage cavity 11, so that the mechanical arm can conveniently pick up the diaphragm 40 outside the storage cavity 11.

[0053] Of course, the lead screw can also be directly driven to rotate by the driving mechanism 30 that drives the cabinet door to open and close, during assembly, the power branch of the driving mechanism 30 is connected with the coupling 14 to drive the cabinet door and the pushing rod to rotate respectively.

[0054] Further, the cabinet body 10 includes two storage cavities 11 and two cabinet doors, the openings of the two storage cavities 11 are opposite to each other, and the two cabinet doors are used to open or close the storage cavities 11 when rotating, and the driving assembly is provided with two driving assemblies, and the two driving assemblies are used to drive the two cabinet doors to rotate.

[0055] Specifically, in some laminated devices, different specifications of diaphragms 40 can be used, so in the embodiment, two storage cavities 11 are arranged in the cabinet body 10 to store diaphragms 40 of different specifications, and two driving assemblies are used to drive two cabinet doors to automatically open two storage cavities 11, so that two diaphragms 40 can be conveniently taken at the same time, and the two operations can be performed at the same time, which greatly shortens the overall operation time and improves the use efficiency of the device.

[0056] The technical means disclosed in the technical scheme of the utility model is not limited to the technical means disclosed in the above-mentioned embodiments, and also includes the technical scheme composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the technical field, without departing from the principle of the utility model, some improvements and refinements can be made, and these improvements and refinements are also considered as the protection range of the utility model.
