Description

Technical Field

[0001] The present disclosure relates to the technical field of laminated battery production, and in particular to a laminated battery pole sheet dust removal device and dust removal equipment thereof. Background Art

[0002] In the production process of laminated batteries, a die-cutting machine is required to cut the rolled material into the size required for production, that is, a single electrode sheet. The single electrode sheet is then sent to the punching mechanism via a conveyor belt, so that the punching mechanism can punch multiple electrode sheets into the clip in sequence, so that multiple electrode sheets can be stacked and loaded into the clip for rapid loading by the subsequent stacking machine.

[0003] However, a large amount of dust is generated during the cutting process and the clamping process of the electrode, which makes the electrode easy to stick to dust and cause the battery cell to short-circuit. Therefore, in order to solve the above problems, a new type of material box with a dust removal device has appeared on the market. For example, Chinese patent number CN 103170959B discloses a material box with a dust removal device, and specifically discloses a dust removal cavity, a vacuum cleaner, a brush and a blower mechanism, and also discloses a electrode box, so that multiple electrode sheets can be placed in the electrode box, and then placed in the dust removal cavity for blowing and suction operations to achieve dust removal effect on the electrode sheets.

[0004] However, from the above-mentioned material box Figure 3 It can be seen that since the dust reduction chamber has openings at the top and bottom, dust can easily escape from the openings, causing serious pollution problems in the cleanliness of the production workshop. Utility Model Content

[0044] like Figures 2 to 3As shown, a laminated battery pole sheet dust removal device 10 of an embodiment includes a frame 100, a workbench 200, a lifting assembly 300 and a sheet pressing assembly 400, wherein the workbench 200 is arranged on the frame 100, the lifting assembly 300 is arranged below the workbench 200 and connected to the frame 100, the sheet pressing assembly 400 is arranged above the workbench 200 and is arranged opposite to the lifting assembly 300, and the laminated battery pole sheet dust removal device 10 also includes a first opening and closing dust removal mechanism 500, a second opening and closing dust removal mechanism 600 and a negative pressure extraction assembly 700; please refer to Figure 4 and Figure 5 The first opening and closing dust removal mechanism 500 includes a first frame 510, a first brush assembly 520 and a first ion air knife assembly 530; the second opening and closing dust removal mechanism 600 includes a second frame 620, a second brush assembly 610 and a second ion air knife assembly 630; the first frame 510 and the second frame 620 are relatively movably arranged on the frame 100, so that the first frame 510 and the second frame 620 form a relatively sealed dust removal chamber 900 when they abut against each other, so as to wrap and seal the electrode piece in the dust removal chamber 900, and the first frame 510 and the second frame 620 open the dust removal chamber 900 when they are relatively far away from each other to expose the electrode piece; the first brush assembly 520 is movably arranged on the frame 100; The first frame 510, the first brush assembly 520 is used to clean the dust on the pole piece, the first ion air knife assembly 530 is arranged above the first brush assembly 520, and the first ion air knife assembly 530 is used to blow off the dust on the pole piece; the second brush assembly 610 is movably arranged in the second frame 620, the second brush assembly 610 is used to clean the dust on the pole piece, the second ion air knife assembly 630 is arranged above the second brush assembly 610, and the second ion air knife assembly 630 is used to blow off the dust on the pole piece; the negative pressure extraction assembly 700 is connected to the first frame 510 and / or the second frame 620, and the negative pressure extraction assembly 700 is used to extract dust from the dust removal chamber 900.

[0045] It can be understood that since the jacking assembly 300 is arranged below the workbench 200, the pressing assembly 400 is arranged above the workbench 200 and is arranged opposite to the jacking assembly 300, the jacking assembly 300 and the pressing assembly 400 form a clamping cavity above the workbench 200, thereby achieving clamping and fixing of the pole piece, and the jacking assembly 300 is used to lift the pole piece.

[0046] When in use, the electrode pieces can be stacked and placed in a clip (not shown), and then the clip and the electrode pieces can be placed on top of the lifting assembly 300, and then the supporting plate can be lifted to lift the electrode pieces to the preset dust removal position and pressed and fixed, and then the first frame 510 and the second frame 620 can be driven to move, so that the first frame 510 and the second frame 620 can wrap and seal the electrode pieces in the dust removal chamber 900, and then the first ion wind knife assembly 530, the second ion wind knife assembly 630 and the negative pressure extraction assembly 700 are started at the same time, so that the first ion wind knife assembly 530 and the second ion wind knife assembly 630 can effectively blow The dust falls on the electrode, and the negative pressure extraction component 700 puts the processing chamber in a relatively negative pressure environment, which effectively prevents the blown dust from being blown upward to cause secondary pollution of the electrode by the dust, and avoids the accumulation of dust in the processing chamber to affect the dust removal effect on the electrode. Then, the first brush component 520 and the second brush component 610 are used to clean the dust on the side wall of the electrode, so that the first brush component 520 and the second brush component 610 can more comprehensively clean the adhered dust, effectively avoiding the phenomenon that the dust with strong adhesion cannot be completely removed, and achieving a comprehensive dust removal effect on the surrounding side walls of the electrode with high dust removal efficiency.

[0047] It can also be understood that since the first frame 510 and the second frame 620 are relatively movably arranged on the frame 100, the first frame 510 and the second frame 620 can move back and forth on the frame 100 under the action of an external driver, so that the first frame 510 and the second frame 620 form a relatively sealed dust removal chamber 900 when they abut against each other, and open the dust removal chamber 900 when they are away from each other, thereby reducing the phenomenon of large-area dust escape, thereby effectively avoiding serious pollution problems in the cleanliness of the production workshop.

[0048] In addition, due to the coordinated use of the first frame 510 and the second frame 620, it is not only beneficial for the electrode to flexibly enter and exit the processing chamber, so as to well adapt to the processing of various different specifications of electrodes, that is, to improve the adaptability of the laminated battery electrode dust removal device 10 to the electrode (pole piece); it also reduces the contact and collision between the electrode and the first frame 510 and the second frame 620, effectively avoiding the problem of the electrode being contaminated by dust again after the dust removal is completed.

[0049] It can also be understood that since the first brush assembly 520 is movably disposed on the first frame 510, and the second brush assembly 610 is movably disposed on the second frame 620, the first brush assembly 520 and the second brush assembly 610 can more comprehensively clean the adhered dust, effectively avoiding the phenomenon that the dust with strong adhesion cannot be completely removed, and achieving a comprehensive cleaning and dust removal effect on the electrode.

[0050] In one of the embodiments, the workbench 200 is formed with a movable groove, and the lifting assembly 300 and the pressing assembly 400 are respectively located on both sides of the movable groove. The lifting rod of the lifting assembly 300 is movably inserted into the movable groove to realize the lifting and lowering action of the carrying plate in the magazine, so that the lifting assembly 300 can complete the feeding, unloading and clamping of the electrode.

[0051] In one embodiment, the lifting assembly 300 includes a lifting rod and a lifting seat. The lifting seat is located below the movable groove and connected to the frame 100. The lifting rod is movably arranged on the lifting seat and movably penetrates the movable groove.

[0052] In one embodiment, the pressing plate assembly 400 includes a connecting seat, a connecting rod and a pressing plate. The connecting seat is located above the movable groove and is connected to the frame 100. The connecting rod is movably arranged on the connecting seat, and the pressing plate is connected to one end of the connecting rod facing the lifting rod, so that the pressing plate can be lifted and lowered under the action of an external driver to clamp and fix the pole piece. In the present disclosure, the movable arrangement of the lifting rod and the lifting seat, and the movable arrangement of the connecting rod and the connecting seat can be realized by using existing technologies, and therefore, no specific description is made in the present disclosure.

[0053] like Figure 4 As shown, in one embodiment, the first frame body 510 forms a first semi-open cavity 511, and the second frame body 620 forms a second semi-open cavity 621, and the side walls of the first semi-open cavity 511 and / or the second semi-open cavity 621 are formed with a jacking-into-avoidance groove and a pressing plate extending into the avoidance groove, and the jacking-into-avoidance groove and the pressing plate extending into the avoidance groove are arranged opposite to each other.

[0054] It can be understood that since the side walls of the first semi-open cavity 511 and the side walls of the second semi-open cavity 621 are respectively formed with a lifting-up entering avoidance groove and a pressing plate extending into the avoidance groove, when the first frame 510 and the second frame 620 are closed, the lifting-up entering the avoidance groove can provide a receiving space for the lifting rod, and the pressing plate extending into the avoidance groove can provide a receiving space for the connecting rod, so as to ensure that the first frame 510 and the second frame 620 can form a relatively sealed processing chamber when closed, more effectively reduce the phenomenon of large-area dust escape, thereby effectively avoiding serious pollution problems in the cleanliness of the production workshop.

[0056] like Figure 4 As shown, in one embodiment, the bottom of the first semi-open cavity 511 and / or the second semi-open cavity 621 is formed with an air suction port 5112, and the air suction port 5112 is connected to the air suction pipe of the negative pressure extraction component 700. It can be understood that by setting the air suction port 5112 alone at the bottom of the first semi-open cavity 511, or alone at the bottom of the second semi-open cavity 621, or at the bottom of the first semi-open cavity 511 and the second semi-open cavity 621 at the same time, the negative pressure extraction component 700 can well extract the dust in the processing chamber.

[0057] In one embodiment, the negative pressure extraction component includes an exhaust fan, a filter and a collection bin. The exhaust fan is connected to the collection bin through the filter, and the hose of the exhaust fan is connected to the air suction port 5112 to realize the connection setting between the negative pressure extraction component 700 and the processing chamber.

[0058] In a preferred embodiment, the suction port 5112 is disposed at a corner of the first semi-open chamber 511 and / or the second semi-open chamber 621. In a more preferred embodiment, the number of the suction port 5112 and the negative pressure extraction assembly 700 are both four, so as to more comprehensively extract the dust in the processing chamber.

[0059] In one embodiment, the first brush assembly 520 includes a first soft brush member 521, a second soft brush member 522 and a third soft brush member 523, the first soft brush member 521 is movably set on the first side wall of the first semi-open cavity 511, the second soft brush member 522 is movably set on the second side wall of the first semi-open cavity 511, and the third soft brush member 523 is movably set on the third side wall of the first semi-open cavity 511; the first ion wind knife assembly 530 includes a first ion inclined wind knife 531, a second ion inclined wind knife 532 and a third ion inclined wind knife 533, the first ion inclined wind knife 531 is set on the first side wall of the first semi-open cavity 511 above the first soft brush member 521, the second ion inclined wind knife 532 is set on the second side wall of the second semi-open cavity 621 above the second soft brush member 522, and the third ion inclined wind knife 533 is set on the third side wall of the third semi-open cavity above the third soft brush member 523.

[0060] It can be understood that since the first soft brush member 521, the second soft brush member 522 and the third soft brush member 523 are movably arranged in the two semi-open cavities, especially with the use of the first ion tilted wind knife 531, the second ion tilted wind knife 532 and the third ion tilted wind knife 533, the dust on the pole piece can be blown off more comprehensively, as well as the dust on the first soft brush member 521, the second soft brush member 522 and the third soft brush member 523, while ensuring that the dust on the pole piece is completely removed. On the premise of this, it also ensures that the soft bristles of the first soft brush member 521, the second soft brush member 522 and the third soft brush member 523 still have a good cleaning effect on dust after long-term use, which not only extends the replacement cycle of the first soft brush member 521, the second soft brush member 522 and the third soft brush member 523, but also reduces the replacement frequency of the first soft brush member 521, the second soft brush member 522 and the third soft brush member 523, thereby effectively reducing the dust removal cost of the electrode.

[0061] In one embodiment, the second brush assembly 610 is a fourth soft brush member, and the fourth soft brush member is arranged relatively parallel to the third soft brush member 523, and the second ion air knife assembly 630 is a fourth inclined ion air knife, and the fourth inclined ion air knife is arranged above the fourth soft brush member. It can be understood that when the first soft brush member 521, the second soft brush member 522 and the third soft brush member 523 are used in conjunction with the fourth soft brush member, the first ion inclined air knife 531, the second ion inclined air knife 532 and the third ion inclined air knife 533 are used in conjunction with the fourth inclined ion air knife, a comprehensive dust removal effect on the pole piece is achieved, and dust on the pole piece can be blown off comprehensively.

[0062] In one embodiment, the first soft brush member 521 includes a first soft brush 5211 and a first mounting plate 5212 connected to each other. The first mounting plate 5212 is movably disposed on the first side wall of the first semi-open cavity 511 to realize the movable setting of the first soft brush member 521.

[0063] Similarly, the second soft brush member 522 includes a second soft brush and a second mounting plate connected to each other, the second mounting plate is movably disposed on the second side wall of the second semi-open cavity 621, and the second soft brush member 522 is relatively parallel to the first soft brush member 521 to realize the movable setting of the second soft brush member 522.

[0064] Similarly, the third soft brush member 523 includes a third soft brush and a third mounting plate connected to each other, and the third mounting plate is movably disposed on the third side wall of the third semi-open cavity to realize the movable setting of the third soft brush member 523. Of course, the fourth soft brush member also has a structure similar to that of the first soft brush member 521 to realize the movable setting of the fourth soft brush.

[0065] In one embodiment, the first opening and closing dust removal mechanism 500 also includes a first seal, which is arranged on the side wall of the first opening 5111 of the first frame 510, so that the additional first seal can improve the sealing of the dust removal chamber and effectively prevent large-area dust from escaping.

[0066] Furthermore, in one embodiment, the second opening and closing dust removal mechanism 600 also includes a second sealing member, and the second sealing member is disposed on a side wall of the second opening 6211 of the second frame body 620 to better improve the sealing performance of the dust removal chamber.

[0067] In one embodiment, a transparent observation port is formed on the first frame 510 and / or the side wall of the first frame 510. It can be understood that the additional observation port is helpful for the operator to observe the real-time processing of the electrode in the dust removal chamber, so as to deal with abnormal situations in a timely manner.

[0068] In one embodiment, the laminated battery pole sheet dust removal device 10 further includes a protective cover 800, the protective cover 800 is disposed above the frame 100, a material taking operation port 810 is formed on one side of the protective cover 800, and the first frame 510 and the second frame 620 are both located in the protective cover 800 and are relatively movable on the frame 100. It can be understood that the additional protective cover 800 enables the first frame 510 and the second frame 620 to be disposed in the protective cover 800, extending the path for dust to escape, effectively reducing the phenomenon of dust escaping directly from the material taking operation port 810, and effectively reducing the amount of dust escaping to the outside.

[0069] In one embodiment, the laminated battery pole piece dust removal device 10 further includes a clip, which is detachably arranged in the movable groove of the workbench 200, and a receiving cavity is formed in the clip, and the receiving cavity is used to stack multiple pole pieces, and the supporting plate of the clip is movably arranged in the receiving cavity. It can be understood that since the clip is detachably arranged in the movable groove of the workbench 200, it is convenient for the operator to take it, and since the receiving cavity is formed in the clip, the pole piece can be detachably placed in the receiving cavity, which is convenient for the operator to take it away, and since the supporting plate is movably arranged in the receiving cavity, the lifting rod can lift the supporting plate to realize the feeding and unloading of the pole piece.

[0070] Compared with the prior art, the present invention has at least the following advantages:

[0071] 1) Since the first frame body 510 and the second frame body 620 are relatively movablely arranged on the frame 100, the first frame body 510 and the second frame body 620 can move back and forth on the frame 100 under the action of an external driver, so that the first frame body 510 and the second frame body 620 form a relatively sealed dust removal chamber 900 when they abut against each other, and open the dust removal chamber 900 when they are away from each other, that is, reduce the phenomenon of large-area dust escape, thereby effectively avoiding serious pollution problems in the cleanliness of the production workshop.

[0072] 2) In addition, due to the coordinated use of the first frame 510 and the second frame 620, it is not only beneficial for the electrode to flexibly enter and exit the processing chamber, so as to well adapt to the processing of various different specifications of electrodes, that is, to improve the adaptability of the laminated battery electrode dust removal device 10 to the electrode (pole piece); it also reduces the contact and collision between the electrode and the first frame 510 and the second frame 620, and effectively avoids the problem of the electrode being contaminated by dust again after the dust removal is completed.

[0073] 3) Since the first brush assembly 520 is movably disposed on the first frame 510, and the second brush assembly 610 is movably disposed on the second frame 620, the first brush assembly 520 and the second brush assembly 610 can more comprehensively clean the adhered dust, effectively avoiding the phenomenon that the dust with strong adhesion cannot be completely removed, and achieving a comprehensive cleaning and dust removal effect on the electrode.
