Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to a film tearing device. Background Art

[0002] In the battery manufacturing process, liquid injection and formation is a relatively critical step, and the effect of liquid injection and formation directly determines the performance of the battery. The current process of battery liquid injection and formation is: inject liquid into the battery once → insert the glue nail for the first time to temporarily seal the liquid injection hole → stand at high temperature → pull the nail → negative pressure formation → insert the nail for the second time → stand at high temperature → pull the nail → secondary liquid injection → welding of the sealing nail for final sealing. This traditional glue nail pre-sealing process is prone to the phenomenon of foreign matter being introduced into the liquid injection hole when inserting the sealing glue nail for temporary sealing, the glue nail being skewed resulting in insufficient sealing, and the outer periphery of the liquid injection hole being contaminated resulting in welding of the sealing nail. In order to solve the above problems, a pre-sealing process has been developed that uses a sealing film instead of glue nails to temporarily seal the liquid injection hole during the liquid injection process. This process requires the sealing film to be torn off the battery before the second liquid injection. At present, during the process, the battery is usually manually torn off, and the work efficiency is low. In addition, the existing battery film tearing equipment is used to tear off the packaging film on the surface of the battery, which is not suitable for the above new process.

[0003] Therefore, it is urgent to develop a film-tearing mechanism that can remove the sealing film attached to the battery filling hole. Utility Model Content

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The utility model discloses a film peeling device, which is used to remove the sealing film 20 attached to the battery injection hole. Figure 1 As shown, the film tearing device of this embodiment includes a frame 100, a film tearing transport line 200, a collecting mechanism 300 and a film tearing mechanism 400. The film tearing transport line 200 is installed on the frame 100 and is used to transport vertically placed batteries 10. The collecting mechanism 300 is arranged on the frame 100 in parallel with the film tearing transport line 200 and is used to collect the sealing film 20. The film tearing mechanism 400 is arranged on the frame 100 and is located between the film tearing transport line 200 and the collecting mechanism 300. The film tearing mechanism 400 is used to remove the sealing film 20 from the battery 10 and transport the sealing film 20 to the collecting mechanism 300.

[0036] First of all, it should be noted that the frame 100 serves as a supporting mechanism for the entire film tearing device. The frame 100 may be a frame structure or a sealed box structure. The control system of the entire film tearing device and the electrical control structures of the remaining components may be placed inside the frame 100. A support plate is provided on the top of the frame 100, and the film tearing transport line 200, the collection mechanism 300, and the film tearing mechanism 400 are all installed on the support plate, which can ensure stable support for the film tearing transport line 200, the collection mechanism 300, and the film tearing mechanism 400.

[0037] It is understandable that, in the actual working process, before the secondary liquid injection, the battery 10 with the sealing film 20 is placed on the film tearing transport line 200. During the transportation of the film tearing transport line 200, the battery 10 is always in a vertical state, which can avoid the phenomenon of the battery 10 tipping over and causing electrolyte leakage during the operation of the film tearing device. When the film tearing transport line 200 transports the battery 10 to the position corresponding to the film tearing mechanism 400, the film tearing mechanism 400 is used to remove the sealing film 20 from the battery 10, and transport the sealing film 20 to the collection mechanism 300. The torn sealing film 20 is collected by the collection mechanism 300. After the film tearing is completed, the film tearing transport line 200 continues to transport the battery 10 and transports it to the next station. Therefore, the film tearing equipment of this embodiment not only realizes the automatic transportation of the battery 10 to the film tearing station, but also completes the film tearing through the film tearing mechanism 400, realizes the function of automatic film tearing, and improves the film tearing efficiency.

[0038] Optionally, the film-tearing conveying line 200 is provided with a first position detector (not shown), which is used to detect the position of the battery 10. When the battery 10 reaches the specified position, the film-tearing conveying line 200 stops working, so that the battery 10 is in a stationary state during the film-tearing process, thereby facilitating the film-tearing.

[0039] refer to Figure 2As shown, the film tearing mechanism 400 includes a clamping jaw 410, a clamping drive member 420 and a positioning drive assembly 430. The clamping jaw 410 has an open state and a closed state. The clamping drive member 420 is connected to the clamping jaw 410 to drive the clamping jaw 410 to open or close. The positioning drive assembly 430 is connected to the clamping drive member 420. The positioning drive assembly 430 is used to drive the clamping drive member 420 and the clamping jaw 410 to move between the film tearing transport line 200 and the collection mechanism 300. It can be understood that in the actual working process, when the battery 10 reaches the film tearing station, the jaws 410 are in an open state at this time. First, the positioning drive component 430 drives the clamping drive member 420 and the jaws 410 to move to the film tearing station, so that the sealing film 20 is located inside the space opened by the jaws 410, and then the clamping drive member 420 drives the jaws 410 to move so that the jaws 410 are closed to clamp the sealing film 20, and then the positioning drive component 430 drives the jaws 410 to move to the collection station corresponding to the collection mechanism 300. During the movement of the jaws 410, the jaws 410 can drive the clamped sealing film 20 to separate from the battery 10 to complete the film tearing, and finally the jaws 410 are released so that the torn sealing film 20 falls into the collection mechanism 300 for collection. Therefore, by tearing the film by clamping the clamp 410 and then driving the clamp 410 to move, the sealing film 20 can be better torn off the battery 10 as a whole, avoiding the sealing film 20 from remaining on the battery 10, and improving the film tearing effect.

[0040] Further, refer to Figure 2 As shown, the clamping drive member 420 includes a finger cylinder, and the finger cylinder has two movable parts 421 that can be opened and closed. The clamping jaw 410 includes two clamping parts 411, and each clamping part 411 is respectively connected to each movable part 421. Using a finger screw as the clamping drive member 420 can simplify the structure of the entire clamping drive member 420, and facilitate driving the clamping jaw 410 to open and close, thereby facilitating film tearing. Of course, in an alternative embodiment of the utility model, the clamping drive member 420 can also be formed as a mechanism in which a motor drives a screw nut to drive the two clamping parts 411 to move closer or farther, or a structure in which two telescopic cylinders are used to drive the two clamping parts 411 respectively, and is not limited to the above-mentioned technical solution of the finger cylinder.

[0041] Further, refer to Figure 2As shown, the positioning drive assembly 430 includes a fixed seat 431, a lifting drive member 432, a rotating seat 433 and a rotating drive member 434, the fixed seat 431 is used to support the clamping drive member 420, the lifting drive member 432 cooperates with the fixed seat 431 to drive the fixed seat 431 to rise and fall, the rotating seat 433 is used to support the lifting drive member 432, and the rotating drive member 434 is connected to the rotating seat 433 to drive the rotating seat 433 to rotate. First of all, it should be noted that compared with the clamping drive member 420 being directly connected to the lifting drive member 432, the fixed seat 431, as a supporting structure of the clamping drive member 420, can ensure the installation stability of the clamping drive member 420, thereby ensuring the installation stability of the clamping jaw 410. Compared with the lifting drive member 432 being directly connected to the rotating drive member 434, the rotating seat 433 is used as a supporting structure of the lifting drive member 432, thereby ensuring the installation stability of the lifting drive member 432, thereby indirectly ensuring the stability of the clamping jaw 410. It is understandable that, in the actual working process, when the battery 10 moves to the film tearing station, the clamping driver 420 drives the clamping jaws 410 to open, the lifting driver 432 drives the fixing seat 431 to rise, so that the clamping jaws 410 move to a position equal to the height of the sealing film 20 of the battery 10, and the rotating driver 434 drives the rotating seat 433 to rotate, so that the clamping jaws 410 move to a position capable of clamping the sealing film 20. Compared with driving the clamping jaws 410 to move in the horizontal direction, the switching of the position of the clamping jaws 410 by rotation can save more space, and the compactness of the film tearing device is conducive to the miniaturization design of the film tearing device.

[0042] In this embodiment, the lifting drive member 432 is a telescopic cylinder, and the rotating drive member 434 is a rotating cylinder. Thus, the structure of the entire positioning drive assembly 430 can be simplified, the number of parts can be reduced, assembly and maintenance can be facilitated, and manufacturing costs can be reduced.

[0043] Of course, in other embodiments of the utility model, the lifting drive member 432 and the rotating drive member 434 can select electric push rods, motors or other power output mechanisms of the motor-driven transmission assembly according to actual needs. It only needs to ensure that the fixed seat 431 can be lifted and lowered and the rotating seat 433 can be rotated, and is not limited to the above limitations.

[0044] In addition, it should be noted that in other embodiments of the present invention, a vacuum adsorption structure can also be used to achieve film tearing and discarding of the sealing film 20. Specifically, when the battery 10 moves to the specified position, the vacuum adsorption structure descends to absorb the sealing film 20, and then rises to tear the sealing film 20 off the battery 10. Then the vacuum adsorption structure moves to the top of the collection mechanism 300, and the pump body connected to the vacuum adsorption structure is closed. After the adsorption force disappears, the sealing film 20 can fall into the collection mechanism 300. In other words, in other embodiments of the present invention, the film tearing mechanism 400 can also select other mechanisms that can achieve the film tearing function according to actual needs, and is not limited to the above description.

[0045] refer to Figure 3 As shown, the film tearing transport line 200 includes a first transmission component 210 and two first guide components 220. The first transmission component 210 is used to transport the battery 10. In a direction perpendicular to the transport direction of the battery 10, the two first guide components 220 are arranged on the first transmission component 210 at intervals. Each first guide component 220 is provided with a plurality of first guide wheels 221 arranged at intervals along the transport direction of the battery 10. The first guide wheels 221 of the two first guide components 220 correspond to each other and respectively stop at two oppositely arranged side walls of the battery 10. It can be understood that the first transmission component 210 can be a conveyor belt structure or a conveyor chain plate structure, which can be selected according to actual needs. Due to the addition of the first guide component 220, during the process of transporting the battery 10 by the first transmission component 210, the first guide wheels 221 of the two first guide components 220 respectively stop at two oppositely arranged side walls of the battery 10. Through the restriction and guiding effect of the first guide wheel 221, it is ensured that the battery 10 remains in a vertical state during transportation, and the phenomenon of electrolyte leakage caused by the skew of the battery 10 is avoided.

[0046] refer to Figure 3 As shown, the collecting mechanism 300 includes a collecting pipeline 310 and a negative pressure device (not shown in the figure). The collecting pipeline 310 is arranged in parallel with the film tearing transport line 200. An opening 3111 for collecting the sealing film 20 is formed at one end of the collecting pipeline 310. The negative pressure device is connected to the other end of the collecting pipeline 310. The negative pressure device is used to generate negative pressure in the collecting pipeline 310 to collect the sealing film 20. In the actual working process, when the film tearing mechanism 400 moves to the top of the collecting pipeline 310 and releases the sealing film 20, the negative pressure device generates negative pressure in the collecting pipeline 310 to ensure that the sealing film 20 falling under the action of gravity can stably fall into the collecting pipeline 310 from the opening 3111, thereby avoiding the phenomenon of the sealing film 20 flying around, ensuring the cleanliness of the film tearing device during operation, avoiding the phenomenon of other parts of the film tearing device being misplaced into the sealing film 20 and causing the movement to be unsmooth, and facilitating the unified collection of the sealing film 20.

[0047] Further, refer to Figure 3 As shown, the collecting pipeline 310 includes a tapered section 311 and a straight section 312, one end of the straight section 312 is connected to the narrow end of the tapered section 311, and the other end is connected to the negative pressure device; the wide end of the tapered section 311 is open to one side of the film tearing mechanism 400 to form an opening 3111. It can be understood that the wide end of the tapered section 311 is open to the film tearing mechanism 400 to form an opening 3111, so that the collecting pipeline 310 can have a larger opening 3111, ensuring that the sealing film 20 can stably fall into the collecting pipeline 310 from the opening 3111, further avoiding the phenomenon of the sealing film 20 flying around.

[0048] refer to Figure 1 As shown, the film tearing equipment also includes an NG transport line 500 and a conveying mechanism 600. The NG transport line 500 is arranged in parallel with the film tearing transport line 200. The conveying mechanism 600 is arranged above the NG transport line 500 and the film tearing transport line 200. The conveying mechanism 600 is used to transport the battery 10 that failed to tear the film from the film tearing transport line 200 to the NG transport line 500 for recycling. It can be understood that in the actual film tearing process, due to mechanism failure or other unpredictable reasons, the film tearing may be incomplete. If the battery 10 with incomplete film tearing is directly transported to the next process equipment, it will affect the normal progress of the next process. In this embodiment, by setting the NG transport line 500 and the conveying mechanism 600, the battery 10 with incomplete film tearing can be moved away from the film tearing transport line 200, avoiding the battery 10 with incomplete film tearing being directly transported to the next process equipment, thereby ensuring the normal progress of the next process. Specifically, a detection device (not shown) is arranged above the film tearing conveying line 200. When the detection device detects a battery 10 with incomplete film tearing, a signal is sent to the conveying mechanism 600, and the conveying mechanism 600 conveys the battery 10 with failed film tearing from the film tearing conveying line 200 to the NG conveying line 500 for temporary storage. The detection device can be an image recognition device or a structure such as an optical sensor. The device for detecting incomplete film tearing and the control logic can be selected according to the existing technology and need not be described here.

[0049] Further, refer to Figure 4As shown, the NG transport line 500 includes a second transmission component 510 and a second guide component 520. The second transmission component 510 is used to transport the battery 10. Two second guide components 520 are arranged on the second transmission component 510 at intervals along the direction perpendicular to the transport direction of the battery 10. Each second guide component 520 is provided with a second guide wheel 521 arranged at intervals along the transport direction of the battery 10. The second guide wheels 521 of the two second guide components 520 are respectively stopped on the two oppositely arranged side walls of the battery 10. It can be understood that the second transmission component 510 can be a conveyor belt structure or a conveyor chain plate structure, which can be selected according to actual needs. Due to the addition of the second guide component 520, during the process of transporting the battery 10 by the second transmission component 510, the second guide wheels 521 of the two second guide components 520 are respectively stopped on the two oppositely arranged side walls of the battery 10. Through the restriction and guiding effect of the second guide wheel 521, it is ensured that the battery 10 remains in a vertical state during transportation, and the phenomenon of electrolyte leakage caused by the skew of the battery 10 is avoided.

[0050] Further, refer to Figure 5 As shown, the transport mechanism 600 includes a gantry 610, a horizontal drive assembly 620, a lifting drive assembly 630 and a clamping assembly 640. The gantry 610 is installed on the frame 100, and the crossbeam of the gantry 610 is located above the NG transport line 500 and the film tearing transport line 200. The horizontal drive assembly 620 is arranged on the crossbeam. The lifting drive assembly 630 is connected to the horizontal drive assembly 620 and can move in the horizontal direction under the drive of the horizontal drive assembly 620. The clamping assembly 640 is coordinated with the lifting drive assembly 630 in transmission and can be lifted and lowered under the drive of the lifting drive assembly 630. It can be understood that in the actual working process, when the detection device detects a battery 10 with incomplete film tearing, the horizontal drive component 620 drives the lifting drive component 630 to move above the film tearing transport line 200, the lifting drive component 630 drives the clamping component 640 to descend to the position corresponding to the battery 10, and after the clamping component 640 clamps the battery 10, the lifting drive component 630 drives the clamping component 640 to rise, and the horizontal drive component 620 drives the lifting drive component 630 to move above the NG transport line 500, the lifting drive component 630 drives the clamping component 640 to descend to the position corresponding to the NG transport line 500, the clamping component 640 releases the battery 10 and places it on the NG transport line 500, waiting for the staff to process it. In this way, the automatic transportation of the battery 10 with incomplete film tearing is realized without manual transportation, which improves the degree of automation of the film tearing equipment and reduces the labor intensity of the staff.

[0051] Furthermore, the horizontal drive assembly 620 and the lifting drive assembly 630 are both electric lead screw slide structures. The electric lead screw slide structure is a mature product and does not need to be described in detail here.

[0052] Furthermore, refer to Figure 5 As shown, the clamping assembly 640 includes a rotating cylinder 641, a buffer assembly 642 and a clamping cylinder 643. The rotating cylinder 641 is installed on the slide of the lifting drive assembly 630, and the rotating table is connected to the rotating shaft of the rotating cylinder 641. The buffer assembly 642 includes two spaced mounting plates 6421 and a plurality of buffer springs 6422 connected between the two mounting plates 6421. The clamping cylinder 643 is installed on the mounting plate 6421 located below. The clamping cylinder 643 has two movable plates 6431. When the clamping cylinder 643 is working, the two movable plates 6431 can move toward or away from each other. A clamping plate 6432 is connected to each movable plate 6431. In the actual working process, the two clamping plates 6432 can clamp the battery 10.

[0053] Of course, it should be noted that in other embodiments of the present invention, the horizontal drive assembly 620, the lifting drive assembly 630 and the clamping assembly 640 can also select other mechanisms in the prior art according to actual needs, and are not limited to the above description. In addition, the transport mechanism 600 can be directly formed into a six-axis robot arm, or other structures capable of transporting and clamping the battery 10, and is not limited to the above description.

[0054] It should be noted that the film-tearing device is used to remove the sealing film attached to the battery injection hole. In addition, the film-tearing device is applicable to the pre-sealing method disclosed in the Chinese patent application number 202410699819.5. For example, the sealing film 20 includes a first sealing film and a second sealing film. The film-tearing device can remove the first sealing film, the second sealing film or a combination thereof pre-packaged on the battery injection hole.
