Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and in particular relates to a pole piece anti-breaking device. Background Art

[0002] The production and processing of batteries usually involves the production and transportation of strip products such as pole pieces. Strip breakage is prone to occur during the production and transportation of strip products. Due to the physical properties of the materials and the product process, the strip breakage phenomenon cannot be eliminated. The only way to reduce the frequency of strip breaks is through monitoring.

[0003] In existing technology, during the current production process, manual visual inspection is used to monitor the tear-prone areas of strip products, and the production process is interrupted to apply glue to the areas. Although this method can reduce the frequency of strip breakage during the production process, manual visual inspection is less accurate and prone to misjudgment or misidentification, which affects production. In addition, most production equipment is complex, and manual shutdowns can take considerable time. This can easily cause the tear-prone areas of the strip product to be transported a certain distance, requiring workers to re-locate and re-address them, resulting in a long time and reduced production efficiency.

[0032] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0033] In the description of this application, it should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0034] Example 1:

[0035] This embodiment provides a pole piece anti-breaking device, comprising:

[0036] scaffolding;

[0037] The conveying mechanism 1 is installed on the base frame and is used to transport the strip material 9;

[0038] Detection mechanism 2, which is installed on the base frame and is used to detect whether the transported strip material 9 has a risk of breakage;

[0039] The unwinding mechanism includes a connecting belt 3, and the connecting belt 3 is wound and stored on the unwinding mechanism;

[0040] The lifting mechanism is installed on the base frame, and the output end of the lifting mechanism is connected to the connecting belt 3.

[0041] In this technical solution, one end of the connecting belt 3 wound and stored on the unwinding mechanism is withdrawn, and adhesive tape or glue is provided on both sides of this end. One side is bonded and fixed to the output end of the lifting mechanism, and the other side is used to bond and fix to the strip material 9 transported on the conveyor mechanism 1. It is worth noting that the viscosity of the adhesive tape on the connecting belt 3 used to bond to the strip material 9 is greater than the viscosity of the adhesive tape used to bond to the lifting mechanism.

[0042] The working principle of the pole piece anti-breaking device is as follows: the conveying mechanism 1 transports the strip material 9 through the detection mechanism 2, and the detection mechanism 2 detects the strip material 9 to determine whether the strip material 9 has a risk of breaking. Furthermore, the detection mechanism 2 includes a photoelectric sensor, which can be a measuring light curtain. When the transported strip material 9 passes through the measuring light curtain, the light beam is blocked by the material, and it is detected that there is no risk of breaking the strip material 9. The conveying mechanism 1 operates normally to transport the strip material 9 through.

[0043] If there is a risk of the strip-like object breaking, light will be transmitted through the strip-like object when it passes through the measuring light curtain. The light beam of the measuring light curtain is no longer blocked, causing the receiving end of the measuring light curtain to receive the light signal, thereby causing the measuring light curtain to output an alarm signal and the conveying mechanism 1 to stop running. The output end of the lifting mechanism then controls the connecting belt 3 to descend, so that the other side of the connecting belt 3 is bonded to the strip-like material 9. The output end of the lifting mechanism is then reset, and the connecting belt 3 is fixed to the strip-like material 9. Finally, the unwinding mechanism rewinds the connecting belt 3 to a certain length, so that the connecting belt 3 is pulled back and drives the strip-like material 9 to retreat a certain distance along the transportation path, thereby facilitating the staff to quickly connect the strip-like material 9 at the risk of breaking, reducing downtime, resuming production more quickly, and effectively improving production efficiency.

[0044] To sum up, when the pole piece anti-breaking device is working, the conveying mechanism 1 transports the strip material 9, and the detection mechanism 2 accurately detects the strip material 9 in transportation. If there is a risk of strip material 9 breaking and the conveying mechanism 1 stops running, the lifting mechanism controls the connecting belt 3 to adhere to the strip material 9, and then the unwinding mechanism rewinds the connecting belt 3 to pull the strip material 9 back, thereby facilitating the staff to restore the belt connection and thus resume production faster.

[0045] Example 2:

[0046] This embodiment provides a pole piece anti-band break device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] Furthermore, the lifting mechanism includes:

[0048] Connecting piece 4, one end of the connecting belt 3 is connected to the connecting piece 4;

[0049] Two first driving members 5, the output ends of the two first driving members 5 are respectively connected to the two ends of the pressure roller.

[0050] Furthermore, the connecting member 4 is a rubber pressing roller.

[0051] In this technical solution, two first driving members 5 are installed on the base frame, and the two roller shafts of the rubber pressure roller are respectively connected and fixed to the two first driving members 5. One side of the end of the connecting belt 3 is bonded to the side of the rubber pressure roller close to the strip material 9. The two first driving members 5 are used to drive the rubber pressure roller to move, driving the other side of the end of the connecting belt 3 to bond to the strip material 9, so that the strip material 9 can be pulled back when the connecting belt 3 is wound.

[0052] The first driving member 5 can be a pneumatic cylinder or an electric cylinder. Preferably, the first driving member 5 is a pneumatic cylinder, which has a fast response and can control the rapid lifting and lowering of the rubber pressure roller to drive the connecting belt 3 to bond the strip material 9, thereby effectively reducing downtime and having high practicality.

[0053] Example 3:

[0054] This embodiment provides a pole piece anti-band break device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] Furthermore, the unwinding mechanism includes:

[0056] The shutter box 6 is mounted on the base frame;

[0057] The roller is rotatably mounted in the shutter box 6, and one end of the connecting belt 3 is connected to the roller;

[0058] The second driving member 7 is installed on the shutter box 6 and is used to drive the roller to rotate.

[0059] Furthermore, the second driving member 7 is a motor.

[0060] In this technical solution, the pole piece anti-breaking device of the connecting belt 3 is installed on the roller, and then the roller is rotatably installed in the shutter box 6. The shutter box 6 can protect the connecting belt 3 and the roller to prevent the connecting belt 3 and the roller from being damaged by foreign objects. Part of the connecting belt 3 is pulled out from the shutter box 6 and is bonded and fixed to the side of the rubber pressure roller. When the risk of breaking is detected, the first driving member 5 drives the rubber pressure roller to press the connecting belt 3 down and bond it to the strip material 9. The second driving member 7 is installed on the base frame. The second driving member 7 can be a motor. The motor is used to control the rotation of the roller to realize the winding of the connecting belt 3, thereby pulling the strip material 9 back, making it easier for the staff to connect the belt.

[0061] Furthermore, the unwinding mechanism further includes:

[0062] The ratchet bearing 8 , the rotating roller is connected to the output end of the second driving member 7 through the ratchet bearing 8 .

[0063] In this technical solution, when the lifting mechanism controls the connecting belt 3 to be pressed down and bonded to the strip material 9, the connecting belt 3 may be subjected to a downward pulling force, causing the unwinding mechanism to have an unwinding tendency. By setting a ratchet bearing 8, the roller can be prevented from rotating in the direction of the unwinding tendency, thereby playing a locking role, thereby effectively preventing the connecting belt 3 from being pulled out in large quantities.

[0064] Example 4:

[0065] This embodiment provides a pole piece anti-band break device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] Furthermore, the transmission mechanism 1 includes:

[0067] A plurality of traction rollers are installed on the base frame for traction of the strip material 9 for line movement.

[0068] In this technical solution, a number of traction rollers are set up to apply continuous and uniform traction to the strip-like object, thereby ensuring that the strip-like object can move smoothly along the conveying path, effectively avoiding the strip-like object from bending, breaking or deformation during transportation, thereby ensuring that the detection mechanism 2 will not make mistakes in detecting the risk of fracture of the strip-like object, ensuring production stability and improving production efficiency.

[0069] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
