Description

Technical Field

[0001] The utility model relates to the technical field of battery core production, in particular to a self-cleaning transmission mechanism. Background Art

[0002] During the production and manufacturing process of battery cells, relative friction will occur between the aluminum shell of the battery cell and the conveying surface of the conveyor belt. The friction will produce black impurities. Some impurities will remain on the conveyor belt. As the conveyor belt runs, some impurities will stick to the battery cell and be carried by the battery cell, thereby contaminating the surface of the battery cell, further affecting the production of subsequent processes and affecting the quality of the battery cell and battery.

[0003] In the prior art, the cleaning brush and the scraper are fixedly arranged along the conveying direction, and the conveying surface of the conveyor belt will pass through the cleaning brush and the scraper in sequence. When passing through the cleaning brush, the conveying surface rubs against the cleaning brush, and the cleaning brush loosens the impurities adhering to that position. When passing through the scraper, the impurities are guided and collected into the dust box. However, the scraper is different from the cleaning brush. It has a certain hardness. The degree of contact between the scraper and the conveying surface has a great influence on the cleaning effect of the impurities and the structure of the conveyor belt. When a gap is retained between the scraper and the conveying surface, impurities will inevitably remain on the conveying surface. When the scraper contacts the conveying surface, the transmission resistance of the conveyor belt is increased, and the conveyor belt will be scratched during long-term operation. This requires that the scraper and the conveying surface must always maintain an appropriate degree of contact, but in actual operation, the adjustment of the degree of contact is time-consuming and labor-intensive, and difficult to implement, and the scraper is easily affected by the fluctuation of the conveyor belt to cause position displacement.

[0004] Therefore, a self-cleaning transmission mechanism is urgently needed to solve the above problems. Utility Model Content

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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] like Figure 1As shown, this embodiment provides a self-cleaning transmission mechanism, which includes a support structure 100, a transmission belt 200 and a cleaning component. The self-cleaning transmission mechanism can be used to transmit battery cells, avoid impurities adhering to the battery cells, improve the quality and safety performance of the battery cells, improve the cleaning effect of the transmission belt 200, reduce the resistance of the transmission belt 200, reduce the damage of the transmission belt 200, and facilitate use.

[0039] The conveyor belt 200 is arranged on the supporting structure 100, and the conveyor belt 200 extends along its own conveying direction. The supporting structure 100 serves as a carrier of the conveyor belt 200, and its specific structural form can refer to the prior art and is not limited here.

[0040] The cleaning assembly is used to realize automatic cleaning of the conveyor belt 200. Specifically, Figure 1 As shown, the cleaning assembly includes a brush sweeping assembly 300, a collection box 400 and a driving assembly 500. The brush sweeping assembly 300 is attached to the conveying surface of the conveyor belt 200. The brush sweeping assembly 300 and the conveying surface can slide relative to each other. The collection box 400 is provided with a collection port 401. The collection port 401 is located on the upstream side of the brush sweeping assembly 300 in the conveying direction. The collection port 401 is located below the conveying surface. The driving assembly 500 is connected to the brush sweeping assembly 300. The driving assembly 500 can drive the brush sweeping assembly 300 to sweep the impurities on the conveying surface toward the collection port 401. When the brush sweeping assembly 300 is brushing on the conveying surface, it will undergo a certain adaptive deformation, rather than being in rigid contact with the conveying surface.

[0041] During the operation of the conveyor belt 200, the conveying surface of the conveyor belt 200 slides relative to the brush sweeping assembly 300, and the impurities on the conveying surface are blocked by the brush sweeping assembly 300 on the upstream side of the brush sweeping assembly 300. The driving assembly 500 drives the brush sweeping assembly 300 to sweep the impurities on the upstream side of the brush sweeping assembly 300 toward the collection port 401. Under the sweeping movement of the brush sweeping assembly 300 and the action of its own gravity, the impurities fall from the collection port 401 into the collection box 400, thereby achieving the automatic cleaning effect of the conveyor belt 200 and preventing the impurities from adhering to the battery cells. In addition, when the brush sweeping assembly 300 is stationary, the impurities on the conveying surface will still be blocked by the brush sweeping assembly 300 on the upstream side of the brush sweeping assembly 300, so that the other positions of the conveyor belt 200 maintain the cleaning effect and prevent the impurities from adhering to the battery cells. After a certain amount of impurities accumulate on the upstream side, the driving assembly 500 drives the brush sweeping assembly 300 to sweep the impurities into the collection box 400.

[0042] The brush sweeping component 300 is in contact with the conveying surface and, driven by the driving component 500, sweeps the impurities on the conveying surface. It is difficult for impurities to remain on the conveying surface, and the impurities fall into the collecting box 400 below the conveying surface, so that the impurities are collected in a timely and concentrated manner, thereby improving the cleaning effect of the conveyor belt 200. The brush sweeping component 300 is not a hard structure like a scraper. While maintaining the cleaning effect, it also achieves the technical effect of reducing the running resistance of the conveyor belt 200 and not easily damaging the conveyor belt 200. Moreover, the contact between the brush sweeping component 300 and the conveying surface has a certain degree of adaptability, and does not require extremely high precision like a scraper. It is easy to use while maintaining a good cleaning effect and reducing damage to the conveyor belt 200.

[0043] The driving component 500 can drive the brushing component 300 at a fixed time, and when the impurities accumulate to a certain amount on the upstream side of the brushing component 300, the impurities are swept into the collection box 400, saving costs. The driving component 500 can also continuously drive the brushing component 300 to brush and clean the conveyor belt 200 in real time to achieve the best cleaning effect.

[0044] like Figure 2 As shown, optionally, the brushing assembly 300 includes a swing arm 301 and a cleaning member 303 disposed on the swing arm 301. The cleaning member 303 is attached to the conveying surface of the conveyor belt 200 and can slide relative to the conveying surface. The output shaft 502 of the driving assembly 500 is connected to the swing arm 301 in a transmission manner to drive the swing arm 301 to swing back and forth. The swinging of the swing arm 301 drives the cleaning member 303 to sweep impurities into the collection box 400. The structure is simple and the cleaning effect is good. When the cleaning member 303 is brushing on the conveying surface, a certain adaptive deformation will occur, rather than rigidly contacting the conveying surface. The cleaning member 303 can be a cloth, a brush, a sponge, etc.

[0045] The driving assembly 500 drives its output shaft 502 to rotate forward and reverse, and the output shaft 502 drives the swing arm 301 to swing, so that the cleaning member 303 on the swing arm 301 approaches or moves away from the collecting port 401. When the cleaning member 303 approaches the collecting port 401, the impurities on the conveying surface are swept toward the collecting port 401, so that the impurities are swept into the collecting box 400. When the cleaning member 303 moves away from the collecting port 401, it is reset. The swing speed and the reciprocating swing cycle of the swing arm 301 can be adjusted to adapt to the actual working conditions. In other embodiments, the driving assembly 500 can also drive the brush sweeping assembly 300 to reciprocate and translate on the conveying surface, which can also realize the impurities being swept into the collecting box 400 and the reset of the brush sweeping assembly 300.

[0046] In a specific embodiment, Figure 2As shown, the structure of the cleaning component is implemented as follows: the support structure 100 includes a support table 101 extending in the same direction as the conveyor belt 200, the conveyor belt 200 is arranged on the support table 101, the drive assembly 500 is arranged on the support table 101 and is located on one side of the conveyor belt 200 in the width direction, the output shaft 502 is perpendicular to the conveying surface, one end of the swing arm 301 is arranged on the output shaft 502, the swing arm 301 is located on one side of the conveying surface, and the cleaning member 303 is located between the swing arm 301 and the conveying surface. The structure is simple and the layout is reasonable. In this embodiment, the support structure 100 also includes a support frame 102, and the support table 101 is arranged on the support frame 102 and supported by the support frame 102. The motor and the regulator for driving the conveyor belt 200 to circulate are arranged on the support structure 100.

[0047] In one embodiment, Figure 2 As shown, the cleaning member 303 is fixed on the side of the swing arm 301 facing the conveying surface. The swing arm 301 swings to drive the cleaning member 303 to sweep back and forth on the conveying surface, and sweeps the impurities on the conveying surface into the collection box 400. In this embodiment, the cleaning member 303 can be a brush. In another embodiment, the cleaning member 303 can be a cleaning roller, which can be rotatably mounted on the swing arm 301. The swing arm 301 swings to drive the cleaning roller to roll back and forth on the conveying surface, and sweeps the impurities on the conveying surface into the collection box 400. Exemplarily, the cleaning roller can be a roller wrapped with a dry cloth structure.

[0048] like Figure 2 As shown, optionally, the self-cleaning transmission mechanism further includes a fixed support 600 and a bearing 700 both disposed on the support platform 101, the fixed support 600 and the bearing 700 are disposed at intervals along the length direction of the output shaft 502, and are both located on one side of the conveyor belt 200 in the width direction, the driving assembly 500 includes a driving member 501 and an output shaft 502 disposed on the driving member 501, the driving member 501 is disposed on the side of the fixed support 600 away from the bearing 700, a through hole 601 is provided on the fixed support 600, the output shaft 502 passes through the through hole 601 from the driving member 501 and is disposed on the bearing 700, and the swing arm 301 is disposed on the output shaft 502 between the fixed support 600 and the bearing 700. The fixed support 600 fixes the driving member 501, and the output shaft 502 is constrained by the driving member 501 and the bearing 700, so as to reduce the deviation of the output shaft 502 during the rotation process, thereby achieving the accuracy of the swing position of the swing arm 301. In this embodiment, the driving member 501 and the output shaft 502 are integrally formed into a servo motor. The servo motor has fast response and high precision, which facilitates accurate control of the swing arm 301 .

[0049] like Figure 2As shown, specifically, the fixed support 600 can be a "Z"-shaped folding plate, the lower horizontal plate of the folding plate is fixed to the support platform 101 by fasteners, the vertical plate of the folding plate extends upward from its lower horizontal plate so that the upper horizontal plate at the upper end of the vertical plate is suspended above the bearing 700, the driving member 501 is fixed to the upper horizontal plate by fasteners, and the swing arm 301 is arranged between the upper horizontal plate and the bearing 700.

[0050] like Figure 2 As shown, optionally, a shaft hole 302 for the output shaft 502 to pass through is provided on the swing arm 301, the inner wall of the shaft hole 302 is connected to the outer wall of the output shaft 502 by a first flat key, and the output shaft 502 is connected to the bearing 700 by a second flat key. The first flat key and the second flat key are used to achieve torque transmission, and the servo motor switches back and forth in forward and reverse rotation during operation. The first flat key and the second flat key can ensure the accuracy of the swing amplitude of the swing component during high-speed movement.

[0051] During the operation of the conveyor belt 200, the problem of battery leakage also occurs from time to time. The electrolyte drips on the conveyor belt 200. If it takes too long, it cannot be cleaned up manually. In order to facilitate the cleaning of the electrolyte spilled on the conveyor surface and prevent the electrolyte from crystallizing on the conveyor belt 200, Figure 1 As shown, optionally, the self-cleaning transmission mechanism also includes a spraying assembly 800 disposed on the support structure 100, and the spraying assembly 800 is used to spray an electrolyte cleaning agent onto the transmission belt 200. The electrolyte cleaning agent has the characteristic of being compatible with the electrolyte, and the electrolyte is easily soluble in the electrolyte cleaning agent. The specific material of the electrolyte cleaning agent is not limited. In the present embodiment, the electrolyte cleaning agent is industrial alcohol. During operation, the electrolyte cleaning agent is sprayed at the location where the electrolyte is spilled. The electrolyte cleaning agent and the electrolyte are compatible with each other to form a mixed liquid. As the transmission belt 200 circulates, the mixed liquid is transmitted to the brushing assembly 300 and is brushed by the brushing assembly 300. The spraying assembly 800 and the brushing assembly 300 spray and sweep one by one, thereby jointly achieving the cleaning of the electrolyte.

[0052] Specifically, Figure 1As shown, the spray assembly 800 includes a detergent pot 801, a conduit 802, a spray gun 803, a nozzle 804 and a connecting pipe 805. The detergent pot 801 and the spray gun 803 are both arranged on the support structure 100, the spray gun 803 is connected to the detergent pot 801 through the conduit 802, and the nozzle 804 is connected to the spray gun 803 through the connecting pipe 805. The detergent pot 801 contains an electrolyte detergent, and the electrolyte detergent is transported to the spray gun 803 through the conduit 802, and the spray gun 803 transports the electrolyte detergent from the connecting pipe 805 to the nozzle 804 for spraying. The spray gun 803 is controlled by a solenoid valve to control the spraying of the liquid, which is convenient for automatic operation. The solenoid valve can be adjusted and optimized manually in terms of electricity to achieve the desired spraying frequency. The amount of liquid sprayed by the spray gun 803 through the nozzle 804 can also be adjusted. To facilitate the addition of electrolyte detergent, the detergent pot 801 and the conduit 802 are detachably connected, such as by threaded connection.

[0053] Optionally, the spray assembly 800 includes a plurality of nozzles 804 with different spraying ranges, and each nozzle 804 is selectively and detachably arranged on the connecting pipe 805. By replacing different nozzles 804, the desired spraying area size can be achieved.

[0054] Optionally, the connecting tube 805 is a bendable and shaped hose, one end of the connecting tube 805 is arranged on the spray gun 803, and the nozzle 804 is arranged at the other end of the connecting tube 805. In other words, the connecting tube 805 can be bent and shaped arbitrarily, so as to change the position and angle of the nozzle 804, so as to facilitate manual adjustment of the nozzle 804 according to the actual situation on site, so as to align the electrolyte spraying on the conveyor belt 200. In this embodiment, the connecting tube 805 is a metal shaped hose. Specifically, the spray gun 803 is arranged on the side of the support platform 101 in the width direction, and the nozzle 804 can be directed to the upper side or the lower side of the conveyor belt 200 by bending the gooseneck-shaped connecting tube 805.

[0055] like Figure 1 As shown, optionally, the self-cleaning transmission mechanism also includes a manipulator 900 movably arranged on the support structure 100, and the manipulator 900 is located on the downstream side of the brush sweeping assembly 300 in the transmission direction. The conveyor belt 200 on the downstream side of the brush sweeping assembly 300 is used to transmit the battery cells, and the manipulator 900 is used to grab the discharge cells. The brush sweeping assembly 300 and the manipulator 900 do not interfere with each other, so as to avoid the brush sweeping assembly 300 affecting the manipulator 900 in grabbing the discharge cells. The specific structure and working principle of the manipulator 900 can refer to the prior art and will not be repeated here.

[0056] Combination Figure 1 and Figure 2As shown, in this embodiment, the collection box 400 is arranged below the upstream end of the conveyor belt 200, the collection port 401 opens upward, the projection of the upstream end of the conveyor belt 200 in the vertical direction is located in the collection port 401, the brush sweeping assembly 300 is located on the upper side of the conveyor belt 200, and the nozzle 804 is located on the lower side of the conveyor belt 200. The conveyor belt 200 is a circulating turnover belt, and the conveying surface on the upper side of the conveyor belt 200 is used to convey the battery cells. The upstream end of the conveyor belt 200 is the starting end of the conveyor belt 200 in the conveying direction, where the conveyor belt 200 turns from the lower side to the upper side. The nozzle 804 and the brush sweeping assembly 300 are respectively located on the upper and lower sides of the conveyor belt 200 to prevent the nozzle 804 from interfering with the movable brush sweeping assembly 300. The collection box 400 is arranged at the starting end, and when the conveyor belt 200 rotates from the lower side to the upper side, the brush sweeping assembly 300 swings just to scrape the mixed liquid and impurities into the collection box 400. The arrangement of the brushing assembly 300 and the collecting box 400 only occupies the upstream end of the conveyor belt 200, and the other areas of the conveyor belt 200 can be used to convey the battery cells.

[0057] In order to facilitate centralized cleaning of the collection box 400, the collection box 400 is detachably arranged on the support structure 100. In this embodiment, the collection box 400 is fixed to the support frame 102 by screws, and the collection box 400 can be removed by unscrewing the screws, which is convenient for manual cleaning.

[0058] The working principle of the self-cleaning transmission mechanism is as follows:

[0059] When the conveyor belt 200 circulates to transport the battery cells, the driving member 501 drives the swing arm 301 to swing via the output shaft 502. The swing arm 301 swings toward the upstream side of the conveying direction to sweep the impurities on the conveyor belt 200 into the collecting box 400. At necessary positions, such as the discharging process of the liquid injection machine, the spray gun 803 is controlled to spray the electrolyte cleaner onto the conveyor belt 200 through the nozzle 804. The mixed liquid of the electrolyte cleaner and the electrolyte passes through the cleaning member 303 as the conveyor belt 200 moves, thereby cleaning the electrolyte.
