Description

Technical Field

[0001] This invention relates to the field of battery production equipment technology, and more specifically, to a battery cleaning mechanism for battery storage and its method of use. Background Technology

[0002] During battery storage in the production workshop, dust accumulation on the battery surface can easily pose a safety hazard, thus requiring regular cleaning. Currently, battery cleaning largely relies on manual wiping, which is time-consuming, labor-intensive, and inefficient. Mechanical devices for battery cleaning also exist, such as Chinese Patent Publication No. CN113714166A, published on November 30, 2021, which discloses a battery cleaning device for battery storage. Using this device, the operator places a battery requiring cleaning on a first fixed base, and a conveying and wiping system moves the battery. When the battery moves directly under the terminal cleaning system, the terminal cleaning system dehumidifies and removes dust from the battery surface and the outer ring of the terminals. However, this device can only clean one battery at a time, and its efficiency still needs further improvement. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a battery cleaning mechanism and its method for batch cleaning of batteries stored in a storage box, thereby improving cleaning efficiency.

[0004] To achieve these objectives of the present invention, the present invention provides a battery cleaning mechanism for battery storage, comprising:

[0005] The storage box has several ventilation slots, and the battery is housed in the ventilation slots.

[0006] A conveying mechanism for placing the storage box and conveying it forward;

[0007] The spray cleaning section is built above the conveying mechanism and has several downward-inserting protrusions. The space between adjacent protrusions forms a battery passage and corresponds to the ventilation slots. Spray holes are arranged on the side walls of the protrusions. The protrusions are hollow and equipped with plasma generators. Positive pressure gas passes through the plasma generator and is sprayed out from the spray holes to act on the battery surface.

[0008] An air supply unit is located below the conveying mechanism. When the storage box is conveyed to the position corresponding to the air supply unit, the positive pressure airflow provided by the air supply unit blows air from bottom to top onto the battery through the ventilation slot.

[0009] The negative pressure section, located above the conveying mechanism, is used to suck away the airflow from the jet cleaning section and the airflow supply section, as well as the dust being cleaned.

[0010] Furthermore, the sidewall of the slot is configured with a strip-shaped grid structure to allow ventilation, and several air channels are provided along the bottom of the storage box. The air channels are arranged around the slot and communicate with the slot, so that the positive pressure airflow of the air supply unit enters the slot through the air channels.

[0011] Furthermore, there is a gap between adjacent slots, and the gap is configured such that the protrusion can pass through.

[0012] Furthermore, the battery is partially housed in a ventilation slot with the battery electrodes facing upwards, allowing the electrode positions to be cleaned by the spray cleaning unit.

[0013] Furthermore, the protrusion is a V-shaped structure, with both ends of the V-shaped structure closed. The interior is a hollow structure and houses the plasma generator. The nozzles are arranged on the two side walls of the V-shaped structure and face the space through which the battery passes.

[0014] Furthermore, after the battery is inserted into the ventilation slot, there is still extra space for movement. The battery is confined to the movement space constructed by the ventilation slot and the protrusion, and a dynamic balance is achieved under the combined action of the positive pressure airflow provided by the airflow supply unit and the positive pressure gas provided by the jet cleaning unit.

[0015] Furthermore, the jet cleaning section and the airflow supply section are positioned vertically opposite each other.

[0016] Furthermore, a cover is provided to enclose the spray cleaning unit and the air supply unit, and a negative pressure unit is provided on the cover.

[0017] The present invention provides a method for using the battery cleaning mechanism for battery storage, comprising:

[0018] The storage box is used in the production workshop or warehouse. The battery is inserted into the ventilation slot with the battery electrodes facing upwards.

[0019] When cleaning is required, simply place the storage box on the conveyor mechanism, which will then transport the storage box forward.

[0020] The storage box is positioned below the spray cleaning section, and the battery is located in the battery passage space. Under the action of the plasma generator, positive pressure gas carries a large number of ions and is sprayed out through the nozzle to clean the battery surface.

[0021] The air supply unit supplies positive pressure airflow from below to the storage box, and the positive pressure airflow washes the battery from bottom to top through the ventilation slots.

[0022] The negative pressure section sucks away both gas and dust.

[0023] Furthermore, the airflow supply unit is configured such that the output positive pressure airflow can intermittently lift the battery, allowing the battery to be flexibly subjected to scouring within the space defined by the slot and the protrusion.

[0024] The present invention has at least the following beneficial effects:

[0025] The present invention relates to a battery cleaning mechanism for battery storage, which optimizes and improves the storage box. The storage box has several ventilation slots, and each battery is stored independently in a ventilation slot with the battery electrodes facing upwards. When cleaning is required, the entire storage box is placed on a conveyor mechanism and transported forward. During the transport process, a V-shaped spray cleaning section above the conveyor mechanism corresponds to each battery in space. The V-shaped section sprays positive pressure gas carrying ions through the space to eliminate the static adhesion of dust and clean the battery surface. An airflow section below the conveyor mechanism provides positive pressure airflow, which washes the batteries from bottom to top through the ventilation slots. A dust suction section above the conveyor mechanism sucks away all the airflow and dust, achieving the purpose of batch cleaning and improving cleaning efficiency.

[0026] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to examples, so that those skilled in the art can implement it based on the description.

[0032] like Figures 1-4 As shown, a battery cleaning mechanism for battery storage includes:

[0033] The storage box 10 is provided with several ventilation slots 101, and the battery 20 is housed in the ventilation slots 101.

[0034] A conveying mechanism 60 is used to place the storage box 10 and convey it forward.

[0035] The spray cleaning section 30 is built above the conveying mechanism 60 and has several downward-inserting protrusions 301. The adjacent protrusions 301 form a battery passage space 302 and correspond one-to-one with the ventilation slots 101. Spray holes are arranged on the side walls of the protrusions 301. The protrusions 301 are hollow inside and are equipped with plasma generators 90. Positive pressure gas passes through the plasma generator 90 and is sprayed out from the spray holes to act on the surface of the battery 20.

[0036] An air supply unit 40 is located below the conveying mechanism 60. The storage box 10 is conveyed to a position corresponding to the air supply unit 40. The positive pressure airflow provided by the air supply unit 40 blows air from bottom to top to flush the battery 20 through the ventilation slot 101 of the storage box 10.

[0037] The negative pressure unit 50 is disposed above the conveying mechanism 60 and is used to suck away the airflow sprayed by the jet cleaning unit 30 and the airflow supply unit 40, as well as the dust being cleaned.

[0038] refer to Figure 1 The battery 20 is inserted into the ventilation slot 101 of the storage box 10, and the storage box 10 is mounted on the conveying mechanism 60. The conveying mechanism is preferably a belt conveyor. There is a pair of belt conveyors, which respectively support the two sides of the storage box 10. The belt conveyors rotate synchronously to transport the storage box 10 forward.

[0039] like Figure 2 As shown, when passing under the spray cleaning section 30, the battery 20 and the battery through space 302 correspond one-to-one. The pump body inputs positive pressure gas into the interior of the protrusion 301. Under the action of the plasma generator, a large number of positive and negative ions are generated. The positive pressure gas carries a large number of positive and negative ions and is sprayed out from the nozzle on the side wall of the protrusion. It acts on the battery surface, including the position of the electrode, to eliminate the static adhesion of dust. The positive pressure gas picks up the dust and enters the negative pressure section 50 through the exhaust channel 303 between the spray cleaning sections 30, where it is sucked away by the negative pressure section 50.

[0040] As the airflow passes above the air supply unit 40, the positive pressure airflow output from the air supply unit 40 enters from the bottom of the storage box 10 and flows upward along the inner wall of the battery 20 through the ventilation slot, cleaning the dust from the bottom and surface of the battery 20. Preferably, the air supply unit 40 is also equipped with a plasma generator, so that the positive pressure airflow carries a large number of positive and negative ions to eliminate the electrostatic adhesion of dust on the battery surface, which is then washed away by the positive pressure airflow. The dust then enters the negative pressure unit 50 and is sucked away. Preferably, the air supply unit includes an air pump and an air box, which is closed on all sides except for air holes at the top. Figure 1 In the structure shown, air vents cover the top of the air box, and an air pump is connected to the air box to supply positive pressure airflow. The positive pressure airflow is ejected upwards from the air vents and acts on the bottom of the storage box. Preferably, as follows... Figure 1 and 2As shown, the air box 10 of the air supply unit is positioned horizontally below the conveying mechanism 60 and corresponds to the storage box 10. Preferably, the storage box 20 is fitted snugly against the top of the air box or leaves a slight gap without contact, reducing airflow leakage.

[0041] The negative pressure section 50 is configured to be connected to the negative pressure pump through a pipe. Under the action of the negative pressure pump, the negative pressure section generates negative pressure and draws in air.

[0042] This embodiment is particularly suitable for cleaning square batteries, but can also handle pouch or cylindrical batteries. Simply insert the battery downwards into the ventilation slot. The ventilation slot can be configured to match the battery size, or multiple batteries can be inserted side-by-side into a single slot. This storage box is widely used for temporary storage in production workshops or for battery storage in warehouses. When cleaning is required, simply place the storage box on the conveyor mechanism for batch cleaning. This eliminates the need for manual cleaning of each battery individually, as well as the need to manually remove and place each battery into the cleaning mechanism, effectively improving cleaning efficiency.

[0043] Furthermore, in another implementation, such as Figure 3 and 4 As shown, the side wall of the ventilation slot 101 in the storage box 20 is configured as a strip-shaped grid structure 102 to allow ventilation. Several air passages 106 are arranged along the bottom of the storage box 10. The air passages 106 are arranged around the ventilation slot 101 and communicate with the ventilation slot 101, so that the positive pressure airflow of the air supply unit 40 enters the ventilation slot 101 through the air passages 106.

[0044] Furthermore, there is a gap space 104 between adjacent ventilation slots 101. The gap space 104 is configured to allow the protrusion 301 to pass through. Specifically, the width of the gap space 104 should be greater than the width of the protrusion 301.

[0045] Furthermore, such as Figures 1-3 As shown, the battery 20 is partially housed in the ventilation slot 101, with the electrodes of the battery 20 facing upwards, so that the electrode positions are cleaned by the spray cleaning section 30. Preferably, the battery 20 is partially housed in the ventilation slot 101, which makes the battery 20 more stable and reduces the obstruction of the battery surface by the ventilation slot 101.

[0046] Furthermore, such as Figures 1-3 As shown, the protrusion 301 has a V-shaped structure, which is closed at both ends and has a hollow interior where the plasma generator 90 is located. The nozzles are arranged on the two side walls of the V-shaped structure and face the battery passage space 302. Preferably, the plasma generator is vertically positioned inside the V-shaped structure.

[0047] In this embodiment, the V-shaped structure facilitates smooth passage through the space 104 between adjacent batteries 20. Secondly, the battery passage space 302 constructed by the V-shaped structure has a bottom-to-top shape; from bottom to top, the distance between the sidewall of the V-shaped structure and the sidewall of the battery decreases, resulting in a faster and more turbulent positive pressure airflow, thus improving the rinsing effect on the battery surface. Thirdly, the movement of the battery is confined within the battery passage space 302 constructed by the V-shaped structure, preventing the battery from being pushed upwards out of the slot even with a strong positive pressure airflow. Fourthly, in the battery passage space 302 above the battery, the positive pressure gas ejected by the cleaning jet 30 merges with the upward-rushing positive pressure airflow to form turbulence, effectively cleaning the top of the battery, including the electrode area.

[0048] Furthermore, such as Figures 1-3 As shown, after the battery 20 is inserted into the ventilation slot 101, there is still extra space for movement. The battery is confined to the movement space constructed by the ventilation slot 101 and the protrusion 301, and reaches dynamic equilibrium under the combined action of the positive pressure airflow provided by the airflow supply unit and the positive pressure gas provided by the jet cleaning unit.

[0049] In this embodiment, the surplus space allows the battery room to move and provides more space for the positive pressure airflow from the airflow supply unit 10 to pass through. The positive pressure airflow from the airflow supply unit washes the battery from bottom to top, and when the airflow is strong enough, it can push the battery upwards. The positive pressure gas from the cleaning jet acts on the battery from top to bottom or from the side, thus pressing the battery down. By controlling the pressure of the positive pressure airflow from the airflow supply unit and the positive pressure gas from the cleaning jet, the battery can be driven to move up and down within the movement space, preventing the bottom and sidewalls of the battery from remaining in contact with the ventilation slots and thus not being cleaned. Preferably, the pressure of the positive pressure gas from the cleaning jet is set to a constant value, while the pressure of the positive pressure airflow from the airflow supply unit is set to vary periodically to drive the battery up and down. Conversely, the pressure of the positive pressure airflow from the airflow supply unit can be set to a constant value to drive the battery upwards, while the pressure of the positive pressure gas from the cleaning jet is set to vary periodically, with the downward pressure of the positive pressure gas causing the battery to move up and down. Both methods can achieve dynamic cleaning of the battery.

[0050] Furthermore, such as Figure 1 and 2 As shown, the jet cleaning unit 30 and the airflow supply unit 40 are vertically aligned.

[0051] Furthermore, such as Figure 1 and 2 As shown, a cover 80 is provided to enclose the spray cleaning unit 30 and the air supply unit 40, and a negative pressure unit 50 is provided on the cover 80.

[0052] Furthermore, such as Figure 1 As shown, the cover is mounted on the frame 70, and the conveying mechanism 60 is also mounted on the frame 70. The frame 70 is provided with a guard plate 701, which is located outside the conveying mechanism.

[0053] Furthermore, such as Figure 2 As shown, a pair of electric cylinders 702 are also installed inside the cover. When the storage box is in place, the electric cylinders 702 on both sides extend to fix the storage box. When cleaning is completed, the electric cylinders 702 retract and the storage box can continue to be conveyed forward by the conveying mechanism.

[0054] Furthermore, a position sensor is installed inside the enclosure to detect whether the storage box is in place. The position sensor is connected to the control module, which is connected to the conveying mechanism, the spray cleaning section, the air supply section, the negative pressure section, and the electric cylinder. When the position sensor detects that the storage box is in place, the control module pauses the conveying mechanism and simultaneously controls the electric cylinder to extend and fix the storage box. Then, the spray cleaning section, the air supply section, and the negative pressure section are started to perform cleaning operations. After the cleaning operation is completed, the control module pauses the operation of the spray cleaning section, the air supply section, and the negative pressure section, and controls the electric cylinder to retract. Then, the conveying mechanism is started to transport the storage box forward.

[0055] Furthermore, to facilitate the stacking of storage boxes, such as Figure 3 and 4 As shown, support rods 105 are provided on the top surface of the four corners of the storage box 10. The support rods are detachably fixed to the frame 103 of the storage box through insertion holes; Figure 4 As shown, the storage box 10 has sleeves 107 at the bottom of its four corners. The storage boxes can be stacked by putting the sleeves 107 on the top of the support rod 105, making them convenient for storage.

[0056] Example 1

[0057] A method of using the battery cleaning mechanism for battery storage includes:

[0058] The storage box is used in the production workshop or warehouse. The battery is inserted into the ventilation slot with the battery electrodes facing upwards for storage.

[0059] When cleaning is required, simply place the storage box on the conveyor mechanism, and the control module will control the conveyor mechanism to transport the storage box forward.

[0060] After the storage box arrives below the spray cleaning section, the position sensor detects that it is in position. At this time, the battery is located in the battery passage space. The control module controls the conveying mechanism to pause, and starts the electric cylinder to fix the storage box from both sides. Then, the spray cleaning section, air supply section and negative pressure section are started.

[0061] Under the action of the plasma generator, positive pressure gas carrying a large number of ions is ejected through the nozzle to clean the battery surface.

[0062] The air supply unit supplies positive pressure airflow from below to the storage box, and the positive pressure airflow washes the battery from bottom to top through the ventilation slots.

[0063] The negative pressure section sucks away both gas and dust.

[0064] After cleaning is completed, the control module pauses the spray cleaning section, air supply section, and negative pressure section, controls the electric cylinder to shorten and retract, and then starts the conveying mechanism to continue conveying the storage box forward.

[0065] Furthermore, in another embodiment, the pressure of the positive pressure gas in the jet cleaning section is set to a fixed value, and the pressure of the positive pressure airflow in the airflow supply section is set to change periodically, so that the output positive pressure airflow can intermittently lift the battery, and the battery can be flexibly subjected to scouring within the space defined by the slot and the protrusion.

[0066] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Further modifications can be readily implemented by those skilled in the art.
