Description

Technical Field

[0001] The present application relates to the technical field of silk screen wiping of battery cells, and specifically discloses a device for wiping ink prints from battery cells. Background Art

[0002] This section only involves technical content related to this application, which is not necessarily the disclosed prior art.

[0003] In the related art, a silk screen printing step is required after the battery cell is manufactured, that is, some symbols and texts are printed on the battery cell shell with ink to identify the battery cell model, manufacturer, voltage capacity and other information.

[0004] However, in actual operation, some screen printing may have poor printing, which requires erasure and rework. Currently, most of the wiping is done manually, which easily leads to uneven force. Specifically, if the force is too small, the ink will not be wiped away completely, while if the force is too large, the aluminum-plastic film of the battery cell will be damaged. In addition, manual wiping may also result in repeated wiping of the same area, and the aluminum-plastic film of the battery cell can only withstand a limited number of wipes, which easily increases the damage rate of the repeatedly wiped area of the aluminum-plastic film. In addition, manual wiping also has the problems of low wiping efficiency and high wiping cost. In addition, long-term wiping work can easily cause glove wear and injury to the operator's hand muscles.

[0031] The following combination Figures 1 to 3 The specific embodiment of the battery cell ink mark wiping device is described in detail.

[0032] Reference Figure 1 The battery cell ink mark wiping device provided in this application includes a frame 100, a feeding mechanism 200 and a wiping mechanism 300. The frame 100 has a first direction X, a second direction Y and an up-down direction Z that are perpendicular to each other; the feeding mechanism 200 includes a first linear module 210 and a battery cell fixing assembly 220. The first linear module 210 is arranged on the frame 100 along the first direction X. The battery cell fixing assembly 220 is movably connected to the first linear module 210. The battery cell fixing assembly 220 is suitable for fixing the battery cell 400; the wiping mechanism 300 includes a second linear module 310, an wiping pen 320 and a pressure member. 330, the second linear module 310 is mounted on the frame 100 along the second direction Y, and the second linear module 310 is located above the first linear module 210; the erasing pen 320 is movably connected to the second linear module 310, and the erasing pen 320 is distributed along the up and down direction Z, and the lower end pen head 321 of the erasing pen 320 contacts the silk-screen area of the battery cell 400; the pressure member 330 is connected to the erasing pen 320, and the pressure member 330 exerts downward pressure on the erasing pen 320.

[0033] Specifically, the battery cell ink mark wiping device provided in this application has at least the following advantages:

[0034] In the present application, the feeding mechanism 200 is used to load the material and move the battery cell 400 to the wiping station along the first direction X. The pressure-applying member 330 of the wiping mechanism 300 applies appropriate pressure to the wiping pen 320, so that the pen head 321 of the wiping pen 320 presses against the battery cell 400, and then the wiping pen 320 moves repeatedly along the second direction Y to achieve wiping of the silk screen of the battery cell 400 by the wiping pen 320.

[0035] In the present application, the pressure applied to the erasing pen 320 is stable and appropriate, and the force is uniform. There will be no situation where excessive force is used to damage the aluminum-plastic film of the battery cell 400, or too little force is used to fail to wipe the silk screen completely. Moreover, the wiping path and the number of round trips of the erasing pen 320 are controllable, avoiding the phenomenon of frequent wiping times on the same area of the aluminum-plastic film and an increased damage rate. In addition, the present application has a high wiping efficiency and a low damage rate, saving material and labor costs.

[0036] Furthermore, both ends of the second linear module 310 are supported by the support frame 700 , and the second linear module 310 is located above the first linear module 210 , thereby improving the compactness of the structure and reducing the occupied space.

[0037] In some embodiments, reference Figures 1 to 3 The battery cell ink mark wiping device further includes a driver 500 and a mounting plate 600. The driver 500 is movably connected to the second linear module 310, and the power output end of the driver 500 is adapted to move in the up-down direction Z. The mounting plate 600 is disposed at the power output end of the driver 500 and is provided with a stopper 610 having a stopper hole a. The pen holder 322 of the wiper pen 320 is provided with a stopper hole a, and the upper end of the wiper pen 320 is provided with a step plate 323, which is positioned above the stopper hole a.

[0038] Specifically, during the wiping process, the step plate 323 of the wiping pen 320 is located above the limiting portion 610, that is, the limiting portion 610 does not generate an upward supporting force on the step plate 323, and the pressure applied by the pressure member 330 can be completely transmitted to the battery cell 400 through the wiping pen 320, and the pressure application is controllable; after the wiping is completed, the driving member 500 drives the mounting plate 600 to move upward, so that the limiting portion 610 abuts against the step plate 323 and drives the wiping pen 320 to move upward, so that the pen head 321 of the wiping pen 320 is separated from the battery cell 400, and then the battery cell 400 moves away from the wiping mechanism 300 along the first linear module 210 to complete the unloading.

[0039] Furthermore, during the wiping process, the wiping pen 320 moves back and forth along the second direction Y, and can wipe the linear silk-screened area on the battery cell 400. If the width of the silk-screened area in the first direction X is large, wiping can also be achieved by coordinating the stepping movement of the battery cell 400 on the first linear module 210.

[0040] In particular, the driving member 500 may be, but is not limited to, a lifting cylinder or a lifting hydraulic cylinder.

[0041] In some embodiments, reference Figure 1 and Figure 3The erasing pen 320 is also provided with a limiting rod 324, which is connected to the side of the step plate 323 away from the limiting hole a along the up and down direction Z; the pressure-applying member 330 includes a pressure-adjusting weight assembly, which is sleeved on the limiting rod 324 and presses against the step plate 323.

[0042] In some embodiments, the weight a of the pressure-adjusting weight assembly is 50 g to 500 g, and the weight b of the erasing pen 320 is 48 g to 52 g.

[0043] In the above embodiment, the pressure member 330 can adjust the pressure of the erasing pen 320 on the battery cell 400 by increasing or decreasing the weight of the pressure-adjusting weight assembly. Furthermore, the pressure value is related to the pressure range that the aluminum-plastic film of the battery cell 400 can withstand, the viscosity of the silk-screen ink, the concentration of the wiping liquid, and the pressure that the battery cell 400 body can withstand.

[0044] In particular, during the wiping process, the weight borne by the battery cell 400 is the sum of the weight of the pressure-adjusting weight assembly and the weight of the wiping pen 320 itself.

[0045] It should be noted that the pressure member 330 can also be a press, which can also achieve the purpose of controllable pressure and is also within the scope of protection of this application.

[0046] In some embodiments, reference Figure 1 The interior of the wiping pen 320 has a guide cavity, and the pen head 321 of the wiping pen 320 has a liquid outlet connected to the guide cavity; the battery cell ink mark wiping device also includes a wiping liquid supply component 800, which is arranged on the mounting plate 600, and the wiping liquid supply component 800 is connected to the guide cavity of the wiping pen 320.

[0047] In some embodiments, reference Figure 1 The wiping liquid supply assembly 800 includes a hanging bottle 810 and a drainage tube 820. The hanging bottle 810 is located on the mounting plate 600, above the wiping pen 320, with the bottle mouth of the hanging bottle 810 facing downward. The hanging bottle 810 is filled with wiping liquid; the drainage tube 820 connects the hanging bottle 810 with the diversion cavity of the wiping pen 320, and the drainage tube 820 is arranged in a Z-shaped serpentine shape along the vertical direction.

[0048] In some embodiments, reference Figure 1 The wiping liquid supply assembly 800 further includes a visual dropper 830 and a flow regulator 840 . The visual dropper 830 is provided on the drainage tube 820 . The flow regulator 840 is provided on the drainage tube 820 , and the flow regulator 840 is located downstream of the visual dropper.

[0049] Preferably, the tip 321 of the cleaning pen 320 is wrapped with a dust-free wiping cloth; specifically, the dust-free wiping cloth is wrapped in three layers and secured with rubber bands or other accessories. Under the action of gravity, the wiping liquid continuously drips from the hanging bottle 810 into the diversion cavity of the cleaning pen 320 and seeps out from the dust-free wiping portion of the tip 321. Furthermore, the dripping speed can be controlled by adjusting the flow regulator 840, thereby keeping the dust-free wiping cloth moist at all times and preventing the wiping liquid from overflowing.

[0050] In addition, the dripping speed of the wiping liquid can be observed from the visual dropper 830. The upper part of the visual dropper 830 is a gas cavity, and the wiping liquid is left at the lower part. Under the action of atmospheric pressure, the pressure of the wiping liquid can be kept constant, thereby ensuring that the flow rate of the wiping liquid remains unchanged. The specific operation process can refer to the infusion instrument.

[0051] In particular, the drainage tubes 820 are not distributed directly from top to bottom, but are distributed in a serpentine shape, using the principle of communicating vessels for drainage, thereby preventing the basic flow rate of the wiping liquid from being too fast.

[0052] It should be noted that the erasing pen 320 is a hollow structure and forms a guide cavity. The guide cavity is provided with a liquid inlet from the top of the limiting rod 324 , and the liquid inlet is connected to the drainage tube 820 .

[0053] Specifically, the wiping liquid wipes the ink using the principle of dissolution. The wiping liquid may include a solvent (for dissolution), a surfactant (for increasing permeability and wettability), and other additives (such as co-solvents benzyl alcohol, ethylene glycol butyl ether, etc.).

[0054] In some embodiments, reference Figure 2 The cell fixing assembly 220 includes a carrier plate 221, a fixed positioning member 222, and a movable positioning member. The carrier plate 221 is movably connected to the first linear module 210 and has a cell positioning area in which the cell 400 is placed. The fixed positioning member 222 is fixed to the cell positioning area of the carrier plate 221 and has a folded angle groove that matches the corner of the cell 400. The movable positioning member includes a first movable positioning member 223 and a second movable positioning member 224. The first movable positioning member 223 and the second movable positioning member 224 are respectively arranged on both sides of the cell positioning area along the second direction Y. The first movable positioning member 223 is movably connected and locked to the carrier plate 221 along the first direction X, and the second movable positioning member 224 is movably connected and locked to the carrier plate 221 along the second direction Y.

[0055] Specifically, when loading, first move the supporting plate 221 to one end away from the wiping mechanism 300, then place the battery cell 400 in the battery cell positioning area of the supporting plate 221, and align one corner of the battery cell 400 with the corner groove of the fixed positioning member 222, then adjust the position of the second movable positioning member 224 so that it abuts against one side of the battery cell 400, and finally adjust the position of the first movable positioning member 223 so that it abuts against the other side of the battery cell 400, thereby fixing the battery cell 400; similarly, when unloading, the operation is reversed to the loading process, which will not be repeated here.

[0056] Preferably, corresponding positioning screw holes are provided on the supporting plate 221, the first movable positioning member 223 is provided with a first strip hole distributed along the first direction X, the second movable positioning member 224 is provided with a second strip hole distributed along the second direction Y, and the first strip hole and the second strip hole are respectively provided with a hand-tightening bolt b, which is suitable for locking with the positioning screw hole.

[0057] In some embodiments, reference Figure 1 and Figure 2 The supporting plate 221 has at least two battery cell positioning areas along the second direction Y, and each battery cell positioning area is respectively provided with a fixed positioning member 222 and a movable positioning member.

[0058] Specifically, in an embodiment, the battery cell ink mark wiping device has dual stations or multiple stations. When wiping the battery cell 400 on one of the stations, loading and unloading can be performed on other stations at the same time, saving time. Moreover, the stations are highly integrated, which is conducive to improving work efficiency and reducing space occupancy.

[0059] In some embodiments, the battery cell ink mark wiping device further includes a pressure sensor, and a receiving portion of the pressure sensor is disposed in the battery cell positioning area of the carrier plate 221 .

[0060] Specifically, the battery cell ink mark wiping device also includes a control unit, which is communicatively connected to the first linear module 210, the second linear module 310 and the driving member 500. The control unit can control the feeding position and speed of the battery cell 400, the wiping speed, wiping times and position of the wiping pen 320; the pressure sensor is also communicatively connected to the control unit, and the pressure sensor monitors the force applied to the battery cell 400 in real time. When special circumstances such as the shaking of the wiping pen 320 cause the battery cell 400 to be subjected to excessive force, the pressure sensor feeds back to the control unit, and the control unit controls the relevant mechanisms to stop wiping to avoid damaging the battery cell 400.

[0061] It should be noted that the embodiments in the present application only illustrate the structure of the battery cell ink mark wiping device that is related to the improvement points of the present application, but it does not mean that the battery cell ink mark wiping device of the present application does not have other structures, such as a control unit, a wiping liquid replenishing mechanism, etc. Other structures will not be described one by one here.

[0062] In addition, the present application can be used not only to wipe the ink of the silk screen printing process, but also to wipe the ink of the inkjet printing process. In actual use, a wiping liquid with suitable ingredients can be selected.

[0063] In particular, the battery cell ink wiping device in the present application can also be used for reverse testing purposes, for example, replacing the wiping liquid with an alcohol solution for testing the resistance of the battery cell 400 printed ink to alcohol friction, or replacing the test head with an eraser for testing the resistance of the battery cell 400 printed ink to wear.

[0064] Although the embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the appended claims.
