Description

Technical Field

[0001] The present application relates to the technical field of mixers, and in particular to a ribbon mixer and a battery production line. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] At present, after the battery materials are mixed in the ribbon mixer, materials are likely to remain in the cavity of the ribbon mixer. Usually, personnel are required to enter the cavity of the ribbon mixer to clean the materials in the dead corners. However, during the cleaning process, personnel may step on the ribbon or the motor may rotate accidentally, which poses certain safety hazards. Utility Model Content

[0004] The present application provides a ribbon mixer and a battery production line, which can improve the safety of the ribbon mixer.

[0005] This application is achieved through the following technical solutions:

[0006] In the first aspect, an embodiment of the present application provides a ribbon mixer, which includes a mixer body, a driving mechanism and a brake mechanism, wherein the mixer body has a ribbon shaft extending along its axial direction; the driving mechanism is connected to the ribbon shaft, and the driving mechanism is used to drive the ribbon shaft to rotate along its axial direction; the brake mechanism is used to lock or unlock the ribbon shaft or the output shaft of the driving mechanism.

[0007] In the technical solution of the embodiment of the present application, through the setting of the brake mechanism, the brake mechanism can provide the function of locking or unlocking the ribbon shaft or the output shaft of the driving mechanism. When personnel need to enter the interior of the mixer body for cleaning operations, the brake mechanism is used to lock the ribbon shaft or the output shaft of the driving mechanism to prevent the ribbon shaft or the output shaft from rotating. In this way, when personnel clean the residues inside the mixer body, the ribbon shaft always remains in a fixed and non-rotating state, which is more conducive to the staff to clean the residues inside the mixer body, and the cleaning work is safer, which correspondingly reduces the risk of injury due to personnel stepping on the ribbon shaft or accidental rotation of the motor, thereby improving the safety performance of the ribbon mixer.

[0008] According to some embodiments of the present application, the ribbon mixer also includes a control system, which is electrically connected to the driving mechanism and the braking mechanism; the control system includes a detection module and a control module, the detection module is used to detect the working state of the driving mechanism, and the detection module is electrically connected to the control module; the control module is used to control the braking mechanism to lock the output shaft after the detection module detects that the driving mechanism stops working, so as to prevent the output shaft from rotating.

[0009] In the above scheme, the working state of the driving mechanism can be detected by the detection module. When the detection module detects that the driving mechanism stops working, the control module automatically controls the brake mechanism to lock the output shaft of the driving mechanism after receiving the signal transmitted by the detection module. There is no need to manually control the brake mechanism to lock the output shaft of the output mechanism. It is more automated and simplifies the workload of workers. That is, the mixer body is shut down and the brake mechanism automatically locks the output shaft, which has high safety.

[0010] According to some embodiments of the present application, the detection module includes a current detection module and / or a motor speed module, the current detection module is used to detect the working current of the drive mechanism, and the motor speed module is used to detect the speed of the output shaft.

[0011] In the above scheme, the working current of the driving mechanism can be detected by the current detection module to determine whether the driving mechanism is in a working state, and the detection accuracy is high. The motor speed module can also detect the speed of the output shaft of the driving mechanism. When the speed is zero, it also means that the driving mechanism stops working, and it can also determine whether the driving mechanism is in a working state. When the current detection module and the motor speed module cooperate in detection, the detection accuracy of the working state of the driving mechanism is higher, which can reduce the risk of detection errors of the detection module, thereby improving the safety performance of the ribbon mixer.

[0012] According to some embodiments of the present application, the control system also includes a timing module, which is used for timing. The timing module is electrically connected to the control module, and the control module is used to control the brake mechanism to lock the output shaft after the timing module records that the driving mechanism stops working and a preset time has passed.

[0013] In the above scheme, the output shaft may slip after the driving mechanism stops working. Through the setting of the timing module, the timing module can delay the start of the brake mechanism to lock the output shaft after the driving mechanism stops working, that is, realize the function of delayed locking of the output shaft. The delayed locking has the effect of reducing the risk of the output shaft slipping and forcible braking that may damage the equipment, and less damage to the ribbon mixer.

[0014] According to some embodiments of the present application, the control system also includes a proximity switch assembly and an alarm. The proximity switch assembly is electrically connected to the control module, and the proximity switch assembly is arranged in the brake mechanism. The proximity switch assembly is used to detect whether the brake mechanism locks the output shaft; the alarm is electrically connected to the control module, and the control module is used to control the alarm to send an alarm signal when receiving a signal from the proximity switch assembly that the brake mechanism does not lock the output shaft.

[0015] In the above scheme, through the setting of the proximity switch assembly, the proximity switch assembly can monitor whether the brake mechanism is in place and provide feedback to the control module to further ensure the locking effect of the brake mechanism. When the brake mechanism fails to lock the output shaft of the driving mechanism, the proximity switch assembly will feed back the signal to the control module, and the control module can control the alarm to send an alarm signal to prompt the staff, thereby reducing the risk of accidental injury due to failure of the brake mechanism to lock the output shaft in place, and further improving the safety performance of the ribbon mixer.

[0019] In the above scheme, by setting the bracket, the proximity switch can be stably installed on the pusher of the brake mechanism, so that the proximity switch can cooperate with the sensing end on the action part of the brake mechanism to monitor the action of the brake mechanism.

[0020] According to some embodiments of the present application, the bracket includes a clamp and a vertical pole, the clamp is used to be clamped on the outer peripheral side of the pusher; the vertical pole is connected to the clamp, the vertical pole extends along a side away from the pusher, and the vertical pole is provided with an installation hole for installing a proximity switch.

[0021] In the above scheme, the bracket includes a clamp, through which the bracket can be quickly installed on the pusher, the bracket is easy to assemble and disassemble, and the structure is simple. The vertical pole is extended and arranged on the side away from the pusher, and the proximity switch is installed on the vertical pole, which is conducive to the proximity switch and the sensing end on the action part of the brake mechanism.

[0022] According to some embodiments of the present application, the proximity switch includes a proximity switch body and a fastener threadedly matched with the proximity switch body, the proximity switch body is passed through the mounting hole, and the fastener is located on both sides of the mounting hole to fasten the proximity switch body to the bracket.

[0023] In the above scheme, after the proximity switch body is inserted into the mounting hole of the vertical pole, the fasteners are matched with the proximity switch threads, and the fasteners are located on both sides of the mounting hole, so that the proximity switch body is limited on the vertical pole, and the proximity switch body has high installation stability. When the proximity switch body needs to be disassembled, only the fasteners need to be removed, and the proximity switch body can be separated from the vertical pole. The proximity switch body is easy to assemble and disassemble, which is conducive to subsequent maintenance work.

[0024] According to some embodiments of the present application, the mounting hole is an elongated hole, and the elongated hole is extended along the height direction of the vertical pole.

[0025] In the above scheme, by adopting the mounting hole as a long strip hole, the proximity switch body can be moved along the length direction of the long strip hole, and is locked with fasteners after being adjusted into place, so that the installation position of the proximity switch on the vertical pole is adjustable, thereby reducing the risk of the mounting hole of the vertical pole affecting the assembly of the proximity switch due to position error, reducing the installation difficulty of the proximity switch, and having a wider range of applications.

[0026] According to some embodiments of the present application, the driving mechanism includes a driving motor and a reducer, the output end of the driving motor is connected to the input end of the reducer through a first coupling, the output end of the reducer is connected to the screw shaft through a second coupling, and the brake mechanism is used to lock or unlock the first coupling of the driving mechanism.

[0027] In the above scheme, by setting the reducer, the ribbon shaft can rotate at a low speed to meet the mixing requirements of the ribbon mixer. The output end of the drive motor is connected to the input end of the reducer through the first coupling, the first coupling can realize the function of connecting the output end of the drive motor and the input end of the reducer as one, and the second connecting shaft can realize the function of connecting the output end of the reducer and the ribbon shaft as one.

[0028] According to some embodiments of the present application, the driving mechanism further includes a bearing seat, which is located outside the mixer body and is arranged at a position of the ribbon shaft close to the second coupling.

[0029] In the above scheme, by providing a middle bearing seat between the spiral ribbon shaft and the second coupling, the bearing seat can provide rotational support for the spiral ribbon shaft and the second coupling, so that the spiral ribbon shaft and the second coupling can rotate more stably.

[0030] In a second aspect, an embodiment of the present application further provides a battery production line, which includes the ribbon mixer of any of the aforementioned embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0045] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0046] In some embodiments of the present application, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0047] In some embodiments of the present application, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are accommodated in the case.

[0048] In some embodiments of the present application, the box body can be used as a part of the chassis structure of the vehicle. For example, part of the box body can become at least a part of the floor of the vehicle, or part of the box body can become at least a part of the cross beam and longitudinal beam of the vehicle.

[0053] At present, after the battery materials are mixed in the ribbon mixer, materials are likely to remain in the cavity of the ribbon mixer. Although the ribbon mixer is cleaned through the flushing pipeline, materials will still remain in the dead corners of the cavity of the ribbon mixer. The residue of the materials will affect the purity of the next material mixing of the ribbon mixer, and thus affect the quality of the battery. Therefore, personnel are usually required to enter the cavity of the ribbon mixer to clean the materials in the dead corners. However, during the cleaning process, if the personnel accidentally step on the ribbon or the motor rotates unexpectedly, it will cause harm to the personnel. Therefore, the existing ribbon mixer has certain safety hazards.

[0054] Based on the above considerations, in order to improve the safety of the ribbon mixer, the present application designs a ribbon mixer, which includes a mixer body, a driving mechanism and a brake mechanism. The mixer body has a ribbon shaft extending along its axial direction; the driving mechanism is connected to the ribbon shaft, and the driving mechanism is used to drive the ribbon shaft to rotate along its axial direction; the brake mechanism can lock the output shaft of the ribbon shaft or the driving mechanism.

[0055] In such a ribbon mixer, when personnel need to enter the mixer body for cleaning operations, the brake mechanism is used to lock the ribbon shaft or the output shaft of the driving mechanism to prevent the ribbon shaft or the output shaft from rotating. In this way, when personnel clean the residual materials inside the mixer body, the risk of injury due to personnel stepping on the ribbon shaft or accidental rotation of the motor is reduced.

[0056] The present application embodiment provides a ribbon mixer, please refer to Figure 1 , Figure 2and Figure 3 , Figure 1 This is a schematic diagram of the structure of a ribbon mixer according to some embodiments of the present application; Figure 2 for Figure 1 A is an enlarged schematic diagram; Figure 3 The structural schematic diagram of the ribbon mixer of some embodiments of the present application from another angle. The ribbon mixer 100 includes a mixer body 10, a drive mechanism 20 and a brake mechanism 30. The mixer body 10 has a ribbon shaft 12 extending along its axial direction; the drive mechanism 20 is connected to the ribbon shaft 12, and the drive mechanism 20 is used to drive the ribbon shaft 12 to rotate along its axial direction; the brake mechanism 30 is used to lock or unlock the ribbon shaft 12 or the output shaft of the drive mechanism 20.

[0057] The mixer body 10 refers to a mixing device capable of mixing materials. The mixer body 10 may include a bin 11, a ribbon shaft 12 and a ribbon. The bin 11 is used to contain materials. The ribbon shaft 12 is distributed along the axial direction of the bin 11. One end of the ribbon shaft 12 extends out of the bin 11 and is connected to the output shaft of the driving mechanism 20. The ribbon is distributed on the ribbon shaft 12 along the axial direction of the ribbon shaft 12. Under the rotation of the ribbon shaft 12, the ribbon can mix the materials in the bin 11.

[0058] The driving mechanism 20 refers to a driving component capable of driving the ribbon shaft 12 to rotate, and the driving mechanism 20 may include a driving motor 21 and a reducer 22. The ribbon mixer may also include a base 50, which provides a bearing function for the mixer body 10, the driving mechanism 20 and the brake mechanism 30. The mixer body 10 is mounted on the base 50, the driving motor 21 is mounted on the base 50, the output end of the driving motor 21 is connected to the input end of the reducer 22, and the output end of the reduction motor is connected to the ribbon shaft 12, thereby driving the ribbon shaft 12 to rotate. The output end of the driving motor 21, the input end of the reduction motor, and the output end of the reduction motor can all be referred to as the output shaft of the driving mechanism 20.

[0059] The brake mechanism 30 refers to a locking component that can provide a locking function for the rotating shaft (screw shaft 12 or output shaft). The brake mechanism 30 can lock the screw shaft 12 or the output shaft of the driving mechanism 20 in the working state to prevent the screw shaft 12 or the output shaft from rotating. Of course, the brake mechanism 30 can also unlock the screw shaft 12 or the output shaft. After the unlocked output shaft or screw shaft 12 loses the locking performance of the brake mechanism 30, the output shaft or screw shaft 12 can rotate. The brake mechanism 30 is a prior art and can be a brake component such as an electric hydraulic drum brake or an electromagnetic brake.

[0060] In the technical solution of the embodiment of the present application, through the setting of the brake mechanism 30, the brake mechanism 30 can provide a locking or unlocking function for the ribbon shaft 12 or the output shaft of the driving mechanism 20. When personnel need to enter the mixer body 10 for cleaning operations, the brake mechanism 30 is used to lock the ribbon shaft 12 or the output shaft of the driving mechanism 20 to prevent the ribbon shaft 12 or the output shaft from rotating. In this way, when personnel clean the residues inside the mixer body 10, the ribbon shaft 12 always remains in a fixed and non-rotating state, which is more conducive to the staff to clean the residues inside the mixer body 10, and the cleaning work is also safer, which correspondingly reduces the risk of injury due to personnel stepping on the ribbon shaft 12 or accidental rotation of the motor, thereby improving the safety performance of the ribbon mixer.

[0061] According to some embodiments of this application, please refer to Figure 4 , Figure 4 The figure is a logic diagram of a control system in a ribbon mixer of some embodiments of the present application. The ribbon mixer 100 also includes a control system, which is electrically connected to the drive mechanism 20 and the brake mechanism 30; the control system includes a detection module 41 and a control module 40, the detection module 41 is used to detect the working state of the drive mechanism 20, and the detection module 41 is electrically connected to the control module 40; the control module 40 is used to control the brake mechanism 30 to lock the output shaft after the detection module 41 detects that the drive mechanism 20 stops working, so as to prevent the output shaft from rotating.

[0062] The control system refers to a management system composed of a control subject, a control object and a control medium, which has its own goals and functions. The control module 40 serves as the control subject of the control system.

[0063] The detection module 41 refers to a detection component capable of detecting the working state of the driving mechanism 20 , that is, the detection module 41 can detect whether the driving mechanism 20 is in a working state or a non-working (shutdown) state.

[0064] The detection module 41 can detect the working state of the driving mechanism 20. When the detection module 41 detects that the driving mechanism 20 stops working, the control module 40 automatically controls the brake mechanism 30 to lock the output shaft of the driving mechanism 20 after receiving the signal transmitted by the detection module 41. There is no need to manually control the brake mechanism 30 to lock the output shaft of the output mechanism, which is more automated and simplifies the workload of workers. That is, the mixer body 10 is shut down and the brake mechanism 30 automatically locks the output shaft, which has high safety.

[0065] According to some embodiments of the present application, the detection module 41 includes a current detection module and / or a motor speed module, the current detection module is used to detect the working current of the drive mechanism 20, and the motor speed module is used to detect the speed of the output shaft.

[0066] The current detection module refers to a detection component that can detect the working current of the drive mechanism 20. The current detection module can also be called a current detection circuit or a current power acquisition module. The current detection module can be integrated on the main board of the control system. The motor speed module refers to a detection component that can collect the output shaft speed of the motor.

[0067] The current detection module can detect the working current of the drive mechanism 20 to determine whether the drive mechanism 20 is in working condition, and the detection accuracy is high. The motor speed module can also detect the speed of the output shaft of the drive mechanism 20. When the speed is zero, it also means that the drive mechanism 20 stops working, and it can also determine whether the drive mechanism 20 is in working condition. When the current detection module and the motor speed module cooperate to detect together, the detection accuracy of the working state of the drive mechanism 20 is higher, which can reduce the risk of detection errors of the detection module 41, thereby improving the safety performance of the ribbon mixer.

[0068] According to some embodiments of this application, please continue to refer to Figure 4 , Figure 4 The control system of the ribbon mixer of some embodiments of the present application is a logic diagram. The control system also includes a timing module 42, which is used for timing. The timing module 42 is electrically connected to the control module 40. The control module 40 is used to control the brake mechanism 30 to lock the output shaft after the timing module 42 records that the driving mechanism 20 stops working and a preset time has passed.

[0069] The timing module 42, also called a timer, refers to a timing component that can provide a timing function. The timing module 42 can be integrated on a main board of the control system and provide a timing function after programming.

[0070] Since the output shaft may slip after the driving mechanism 20 stops working, the timing module 42 can delay the start of the brake mechanism 30 to lock the output shaft after the driving mechanism 20 stops working, that is, the function of delayed locking of the output shaft is realized. The delayed locking has the effect of reducing the risk of the output shaft slipping and forcible braking that may damage the equipment, and the damage to the ribbon mixer is smaller.

[0071] It should be noted that output shaft slippage means that after the driving mechanism 20 stops working, the output shaft may rotate slightly due to inertia. This process is called slippage. It takes a certain period of time for the output shaft to be completely stationary and non-rotating.

[0072] According to some embodiments of this application, please continue to refer to Figure 4The control system also includes a proximity switch component 43 and an alarm 44. The proximity switch component 43 is electrically connected to the control module 40. The proximity switch component 43 is arranged on the brake mechanism 30. The proximity switch component 43 is used to detect whether the brake mechanism 30 locks the output shaft; the alarm 44 is electrically connected to the control module 40. When the control module 40 receives a signal from the proximity switch component 43 that the brake mechanism 30 does not lock the output shaft, the alarm 44 is controlled to send an alarm signal.

[0073] An alarm 44 is an electronic product that uses sound, light, air pressure, etc. to remind or warn us that we should take certain actions in order to prevent or prevent the consequences of an event. The alarm 44 is divided into a mechanical alarm 44 and an electronic alarm 44.

[0074] Through the setting of the proximity switch assembly 43, the proximity switch assembly 43 can monitor whether the brake mechanism 30 is in place, and feedback to the control module 40, further ensuring the locking effect of the brake mechanism 30. When the brake mechanism 30 fails to lock the output shaft of the driving mechanism 20, the proximity switch assembly 43 will feedback the signal to the control module 40, and the control module 40 can control the alarm 44 to send an alarm signal to prompt the staff, thereby reducing the risk of accidental injury due to the failure of the brake mechanism 30 to lock the output shaft in place, and further improving the safety performance of the ribbon mixer 100.

[0075] According to some embodiments of the present application, the brake mechanism 30 is an electric hydraulic drum brake.

[0076] The electric hydraulic drum brake is an existing technology and can be purchased directly. Here is a partial description of the structure of the electric hydraulic drum brake. Please refer to Figure 5 , Figure 5 The schematic diagram of the structure of the proximity switch installed in the holding brake mechanism in the ribbon mixer of some embodiments of the present application. The electric hydraulic drum brake includes a pusher 31, a pusher driving rod 32, an action part 33, a connecting rod 34 and a brake mechanism. The pusher 31 is installed on the base 50. The pusher 31 provides a driving function. The pusher 31 can be an electric cylinder. Of course, the pusher 31 can also be a hydraulic cylinder. The output end of the pusher 31 is connected to the pusher driving rod 32, the pusher driving rod 32 is hinged to the action part 33, and the connecting rod 34 is connected to one side of the action part 33.

[0077] The brake mechanism includes two brake shoe assemblies 35 distributed on the left and right. The two brake shoe assemblies 35 are respectively a first brake shoe assembly 351 and a second brake shoe assembly 352. The first brake shoe assembly 351 is hinged to the action part 33, and the second brake shoe assembly 352 is hinged to the side of the connecting rod 34 away from the action part 33. The two brake shoe assemblies 35 are hingedly mounted on the base 50 through the brake seat. Under the pushing action of the pusher 31, the pusher 31 can drive the action part 33 to rotate, and the rotation of the action part 33 can drive the connecting rod 34 to rotate. The connecting rod 34 can make the two brake shoe assemblies 35 approach or move away from each other, thereby realizing the locking or unlocking action of the output shaft of the output mechanism. Each brake shoe assembly 35 includes a brake base, a brake shoe and a brake arm. The brake shoes of the two brake shoe assemblies 35 are provided with brake friction plates on the opposite sides, and contact the output shaft through the friction plates.

[0078] By adopting the electric hydraulic drum brake as the brake mechanism 30 , the electric hydraulic drum brake has a simple structure, is easy to purchase and has a low cost.

[0079] According to some embodiments of this application, please combine Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure in which a proximity switch is installed in a brake mechanism in a ribbon mixer in some embodiments of the present application; Figure 6 The schematic diagram of the structure of the proximity switch assembly of some embodiments of the present application. The proximity switch assembly 43 includes a bracket 430 and a proximity switch 431. The bracket 430 is used to be installed on the pusher 31 of the brake mechanism 30. The proximity switch 431 is arranged at one end of the bracket 430 away from the pusher 31. The proximity switch 431 is used to sense and cooperate with the sensing end on the action part 33 of the brake mechanism 30.

[0080] The bracket 430 is a frame that provides a mounting function for the proximity switch 431 . The bracket 430 is fixedly mounted on the pusher 31 . The proximity switch 431 is mounted on the bracket 430 , so that the proximity switch 431 is connected to the sensing end of the action part 33 of the brake mechanism 30 .

[0081] The proximity switch 431 is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch 431 to the action distance, the switch can be activated without mechanical contact or application of any pressure, thereby providing control instructions to the control system.

[0082] The proximity switch 431 is also called a contactless proximity switch 431. When a metal detection object approaches the sensing area of ​​the switch 431, the switch can quickly issue an electrical command without contact, pressure, or sparks, accurately reflecting the position and stroke of the motion mechanism (acting part 33).

[0083] By setting the bracket 430, the proximity switch 431 can be stably installed on the pusher 31 of the brake mechanism 30, so that the proximity switch 431 can cooperate with the sensing end on the action part 33 of the brake mechanism 30 to monitor the action of the brake mechanism 30.

[0084] According to some embodiments of this application, please refer to Figure 6 , Figure 6 Schematic diagram of the structure of the proximity switch assembly of some embodiments of the present application. The bracket 430 includes a clamp 4301 and a pole 4302. The clamp 4301 is used to be clamped on the outer peripheral side of the pusher 31; the pole 4302 is connected to the clamp 4301, and the pole 4302 extends along a side away from the pusher 31. The pole 4302 is provided with a mounting hole 4303 for mounting the proximity switch 431.

[0085] The clamp 4301 refers to a component that uses one material to hold or clamp another material, and is a fastener. The clamp 4301 includes two semicircular clamp plates and bolts, and the inner side of the two clamp plates may be provided with inner pads. The two sides of the two clamp plates are respectively provided with wing plates, and the wing plates are provided with connecting holes. After the bolts pass through the connecting holes of the wing plates, the clamp 4301 is tightly clamped to the outer peripheral side of the pusher 31.

[0086] The vertical rod 4302 refers to a rod disposed on the clamp 4301 at a side away from the pusher 31 . The vertical rod 4302 is used for the proximity switch 431 to be installed at a specific position.

[0087] The bracket 430 includes a clamp 4301, through which the bracket 430 can be quickly installed on the pusher 31, and the bracket 430 is easy to assemble and disassemble, and has a simple structure. The vertical rod 4302 is extended and arranged on a side away from the pusher 31, and the proximity switch 431 is installed on the vertical rod 4302, which is conducive to the proximity switch 431 and the sensing end on the action part 33 of the brake mechanism 30.

[0088] According to some embodiments of the present application, the proximity switch 431 includes a proximity switch body and a fastener threadedly matched with the proximity switch body. The proximity switch body is passed through the mounting hole 4303, and the fastener is located on both sides of the mounting hole 4303 to fasten the proximity switch body to the bracket 430.

[0089] The proximity switch body is the proximity switch 431, and the fastener is an accessory of the proximity switch 431, and the fastener is a nut. The proximity switch body is installed on the vertical pole 4302 through the fastener.

[0090] After the proximity switch body is inserted into the mounting hole 4303 of the vertical pole 4302, the fasteners are threadedly matched with the proximity switch 431. The fasteners are located on both sides of the mounting hole 4303, so that the proximity switch body is limited on the vertical pole 4302, and the proximity switch body has high installation stability. When the proximity switch body needs to be disassembled, only the fasteners need to be removed, and the proximity switch body can be separated from the vertical pole 4302. The proximity switch body is easy to assemble and disassemble, which is conducive to subsequent maintenance work.

[0091] According to some embodiments of this application, please continue to refer to Figure 6 The mounting hole 4303 is a long strip hole, and the long strip hole is extended along the height direction of the vertical pole 4302.

[0092] By adopting the mounting hole 4303 as a long strip hole, the proximity switch 431 body can be moved along the length direction of the long strip hole, and locked with fasteners after being adjusted into place, so that the installation position of the proximity switch 431 on the vertical pole 4302 is adjustable, thereby reducing the risk of the mounting hole 4303 of the vertical pole 4302 affecting the assembly of the proximity switch 431 due to position error, reducing the installation difficulty of the proximity switch 431, and having a wider range of applications.

[0093] According to some embodiments of this application, please refer to Figure 2 The driving mechanism 20 includes a driving motor 21 and a reducer 22. The output end of the driving motor 21 is connected to the input end of the reducer 22 through a first coupling 23. The output end of the reducer 22 is connected to the spiral shaft 12 through a second coupling 24. The brake mechanism 30 is used to lock or unlock the first coupling 23 of the driving mechanism 20.

[0094] The reducer 22 is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing, and is often used as a reduction transmission device between a prime mover and a working machine.

[0095] A coupling is a device that connects two shafts or a shaft and a rotating part, rotating together during the transmission of motion and power, and does not disengage under normal circumstances.

[0096] By setting the reducer 22, the ribbon shaft 12 can rotate at a low speed to meet the mixing requirements of the ribbon mixer. The output end of the drive motor 21 is connected to the input end of the reducer 22 through the first coupling 23. The first coupling 23 can realize the function of connecting the output end of the drive motor 21 and the input end of the reducer 22 as one body, and the second connecting shaft can realize the function of connecting the output end of the reducer 22 and the ribbon shaft 12 as one body.

[0097] According to some embodiments of this application, please refer to Figure 2The driving mechanism 20 further includes a bearing seat 25 , which is located outside the mixer body 10 , and the bearing seat 25 is arranged at a position of the ribbon shaft 12 close to the second coupling 24 .

[0098] By providing a middle bearing seat 25 between the spiral ribbon shaft 12 and the second coupling 24, the bearing seat 25 can provide rotational support for the spiral ribbon shaft 12 and the second coupling 24, so that the spiral ribbon shaft 12 and the second coupling 24 can rotate more stably.

[0099] An embodiment of the present application also provides a battery production line, which includes the ribbon mixer of any of the aforementioned embodiments.

[0100] In some embodiments, the present application provides a ribbon mixer, please refer to Figures 1 to 6 The ribbon mixer 100 includes a mixer body 10, a driving mechanism 20 and a brake mechanism 30. The mixer body 10 has a ribbon shaft 12 extending along its axial direction; the driving mechanism 20 is connected to the ribbon shaft 12, and the driving mechanism 20 includes a driving motor 21 and a reducer 22. The output end of the driving motor 21 is connected to the input end of the reducer 22 through a first coupling 23, and the output end of the reducer 22 is connected to the ribbon shaft 12 through a second coupling 24. The brake mechanism 30 is used to lock or unlock the first coupling 23 of the driving mechanism 20. The ribbon mixer also includes a control system, which is electrically connected to the driving mechanism 20 and the brake mechanism 30; the control system includes a detection module 41 and a control module 40, the detection module 41 is used to detect the working state of the driving mechanism 20, and the detection module 41 is electrically connected to the control module 40; the control module 40 is used to control the brake mechanism 30 to lock the output shaft after the detection module 41 detects that the driving mechanism 20 stops working, so as to prevent the output shaft from rotating.

[0101] The brake mechanism 30 can provide a locking or unlocking function for the ribbon shaft 12 or the output shaft of the driving mechanism 20. The detection module 41 can detect the working state of the driving mechanism 20. When the detection module 41 detects that the driving mechanism 20 stops working, the control module 40 receives the signal transmitted by the detection module 41, and the control module 40 automatically controls the brake mechanism 30 to lock the output shaft of the driving mechanism 20. There is no need to manually control the brake mechanism 30 to lock the output shaft of the output mechanism, which is more automated and simplifies the workload of workers. After the output shaft of the driving mechanism 20 is locked by the brake mechanism 30, the ribbon shaft 12 or the output shaft is prevented from rotating. In this way, when the personnel clean the residual material inside the mixer body 10, the ribbon shaft 12 always remains in a fixed state, which is more conducive to the staff to clean the residue inside the mixer body 10, and the cleaning work is also safer, which correspondingly reduces the risk of injury due to personnel stepping on the ribbon shaft 12 or the motor accidentally rotating, and improves the safety performance of the ribbon mixer.

[0102] In some embodiments, the control system further includes a timing module 42, which is used for timing, and the timing module 42 is electrically connected to the control module 40, and the control module 40 is used to control the brake mechanism 30 to lock the output shaft after the timing module 42 records that the driving mechanism 20 stops working and the preset time interval. The control system also includes a proximity switch component 43 and an alarm 44, the proximity switch component 43 is electrically connected to the control module 40, the proximity switch component 43 is arranged on the brake mechanism 30, and the proximity switch component 43 is used to detect whether the brake mechanism 30 locks the output shaft; the alarm 44 is electrically connected to the control module 40, and the control module 40 is used to control the alarm 44 to send an alarm signal when receiving a signal from the proximity switch component 43 that the brake mechanism 30 does not lock the output shaft.

[0103] Because the output shaft will slip after the driving mechanism 20 stops working. Through the setting of the timing module 42, the timing module 42 can delay the start of the brake mechanism 30 to lock the output shaft after the driving mechanism 20 stops working, that is, realize the function of delaying the locking of the output shaft, and the delayed locking has the risk of reducing the risk of the output shaft slipping and forcibly braking to damage the equipment, and the damage to the ribbon mixer is smaller. Through the setting of the proximity switch component 43, the proximity switch component 43 can monitor whether the brake mechanism 30 is in place, and feedback to the control module 40, further ensuring the locking effect of the brake mechanism 30. When the brake mechanism 30 does not lock the output shaft of the driving mechanism 20, the proximity switch component 43 will feed back the signal to the control module 40, and the control module 40 can control the alarm 44 to send an alarm signal to prompt the staff, reducing the risk of accidental injury due to the failure of the brake mechanism 30 causing the output shaft to be not locked in place, and further improving the safety performance of the ribbon mixer.

[0104] In some embodiments, the proximity switch assembly 43 includes a bracket 430 and a proximity switch 431. The bracket 430 is used to be installed on the pusher 31 of the brake mechanism 30. The proximity switch 431 is arranged at one end of the bracket 430 away from the pusher 31, and the proximity switch 431 is used to sense and cooperate with the sensing end on the action part 33 of the brake mechanism 30. The bracket 430 includes a clamp 4301 and a vertical rod 4302. The clamp 4301 is used to be clamped on the outer peripheral side of the pusher 31. The vertical rod 4302 is connected to the clamp 4301, and the vertical rod 4302 extends along a side away from the pusher 31. The vertical rod 4302 is provided with a mounting hole 4303 for the proximity switch 431 to be installed. The proximity switch 431 includes a proximity switch 431 body and a fastener threadedly matched with the proximity switch 431 body. The proximity switch 431 body is penetrated through the mounting hole 4303, and the fastener is located on both sides of the mounting hole 4303, so that the proximity switch 431 body is fastened to the bracket 430. The mounting hole 4303 is an elongated hole, and the elongated hole is extended along the height direction of the vertical pole 4302 .

[0105] The bracket 430 can be quickly installed on the pusher 31 through the clamp 4301. The bracket 430 is easy to assemble and disassemble and has a simple structure. The vertical pole 4302 is extended and arranged on the side away from the pusher 31. The proximity switch 431 is installed on the vertical pole 4302, which is conducive to the inductive cooperation between the proximity switch 431 and the sensing end on the action part 33 of the brake mechanism 30. The fastener is threadedly matched with the proximity switch 431, and the fastener is located on both sides of the mounting hole 4303, so that the proximity switch 431 body is limited on the vertical pole 4302, and the proximity switch 431 body has high installation stability. When the proximity switch 431 body needs to be disassembled, it is only necessary to remove the fastener, and the proximity switch 431 body can be separated from the vertical pole 4302. The proximity switch 431 body is easy to assemble and disassemble, which is conducive to subsequent maintenance work. The mounting hole 4303 is formed into a long strip hole, so that the proximity switch 431 body can be moved along the length direction of the long strip hole, and is locked with fasteners after being adjusted into place, so that the mounting position of the proximity switch 431 on the vertical pole 4302 is adjustable, thereby reducing the risk of the mounting hole 4303 of the vertical pole 4302 affecting the assembly of the proximity switch 431 due to position error, reducing the installation difficulty of the proximity switch 431, and having a wider range of applications.
