Description

Technical Field

[0001] This invention relates to a processing production line, and more particularly to an alkaline battery processing production line. Background Technology

[0002] In existing technologies, alkaline battery processing production lines employ ultrasonic cleaning to remove oil stains and electrochemical nickel plating or phosphating to improve the corrosion resistance of the steel shell. A hydraulic press is used to press the mixture into annular positive electrode sheets, or an extruder is used to directly inject the positive electrode slurry into the steel shell to prepare the positive electrode. An automatic laminating machine is used to attach a microporous polypropylene or non-woven fabric separator to the outside of the positive electrode for separator assembly. Zinc powder, carboxymethyl cellulose (CMC), and potassium hydroxide electrolyte are mixed into a uniform negative electrode slurry, which is then injected into the separator using a metered plunger pump. Nitrile rubber or fluororubber sealing rings are used, and a capping machine is used to press the positive electrode cap into the steel shell, compressing and deforming the sealing ring to form a seal. After curing, the production line transfers the battery between different processes to ensure orderly connection between each stage. During the transfer process, a chain conveyor or belt conveyor is used as the main transport carrier. The conveyor belt surface is equipped with positioning grooves matching the battery size to prevent the battery from rolling or shifting during transport.

[0003] Chinese Patent Publication No. CN116093411A discloses a battery processing production line, comprising: a cell loading device capable of storing and conveying a first tray carrying cell cells; a first transfer mechanism and a cutting device, wherein the first transfer mechanism can pick up cell cells from the cell loading device and place them into the cutting device, and the cutting device can cut and modify the nickel strips of the cell cells; a circuit board loading device capable of storing and conveying a second tray carrying circuit boards; a second transfer mechanism, a third transfer mechanism, and a welding device, wherein the third transfer mechanism can pick up circuit boards from the circuit board loading device and place them into the welding device, and the second transfer mechanism can place cell cells from the cutting device into the welding device and overlap the nickel strips with the corresponding circuit boards. In the welding area, the welding device can weld the circuit board and the nickel sheet together to form a battery assembly; a fourth transfer mechanism, a bending mechanism, and a conveying mechanism are included. The fourth transfer mechanism can place the battery assembly from the welding device into the bending mechanism, which can bend the circuit board of the battery assembly. The fourth transfer mechanism can also place the bent battery assembly into the conveying mechanism, which can convey the battery assembly and the semi-finished product respectively. The battery assembly is contained in a covering box to form the semi-finished product; a fifth transfer mechanism and an edge-wrapping device are included. The fifth transfer mechanism can place the semi-finished product from the conveying mechanism into the edge-wrapping device, which can place a Mylar film on the semi-finished product and wrap the Mylar film around the semi-finished product. Therefore, the aforementioned battery processing production line has the following problems: during the transportation process, the lateral movement of the battery during suction causes it to rotate when released, or the sudden change from static friction to sliding friction caused by the suction action and the battery casing during release causes the battery to bounce on the transport line at the moment of release, which in turn causes the battery to tend to tip over. Due to the vibration differences between transport lines or the extended processing time of individual batteries, these vibrations accumulate on the transport line, leading to a tendency for propagated blockages. The tendency to tip over and the tendency for propagated blockages cause batteries to become stuck during transportation. Summary of the Invention

[0004] To address this, the present invention provides an alkaline battery processing production line to overcome the problems in the prior art where, during transportation, the battery tends to rotate upon release due to lateral movement during battery suction, or the sudden change from static friction to sliding friction caused by the suction action and the battery casing during release leads to the battery bouncing on the transport line and thus tending to tip over. Furthermore, the accumulation of vibration differences between transport lines or the extended processing time for individual batteries on the transport line leads to the tendency for propagated blockages. These tipping and propagated blockages cause batteries to become stuck during transportation.

[0005] To achieve the above objectives, the present invention provides an alkaline battery processing production line, comprising: A transport unit, used to transport semi-finished batteries from one processing station to the next adjacent processing station, includes several transport lines; An aspiration unit, connected to the transport unit, is used to place the semi-finished battery on the initial transport line; An ion wind jetting unit is disposed above the transport unit to jet ion wind onto the transport unit; A visual recognition unit, connected to the transport unit, is used to acquire the basic image and basic transport image of the semi-finished battery respectively, and to identify the tilt angle of the semi-finished battery in the initial basic image and the vibration amplitude of the initial transport line, as well as the number of semi-finished batteries at the end position of a single transport line in the basic transport image. A control unit, which is connected to the transport unit, the suction unit, the ion wind jetting unit, and the visual recognition unit, is used to determine a first retention adjustment mode based on the number of semi-finished batteries and a second retention adjustment mode based on the inclination angle of the semi-finished batteries. The first retention adjustment mode includes adjusting the speed difference between adjacent transport lines or determining the ion wind jetting area based on the maximum difference in the number of semi-finished batteries in adjacent transport lines. The second retention adjustment mode includes adjusting the horizontal tangential speed of the suction unit for placing semi-finished batteries or adjusting the placement adsorption pressure based on the vibration amplitude of the initial transport line.

[0006] Furthermore, the visual recognition unit includes: A first camera is set on the starting transport line to capture the initial basic image of the semi-finished battery on the starting transport line; Several second cameras are installed at the end of several sections of the transport line that are not the starting transport line, in order to capture the basic transport images of the semi-finished batteries.

[0007] Furthermore, the ion wind jetting unit includes: An ion air duct is disposed above the transport line to spray ion air onto the semi-finished batteries on the transport line. An ion fan, which is connected to the ion duct, is used to spray ion air into the ion duct. Several valves are connected to the ion duct to control the opening state of corresponding ion duct sections.

[0008] Furthermore, the control unit is connected to the first camera to obtain the tilt angle. If the tilt angle is greater than or equal to a preset second angle, the horizontal tangential speed of the suction unit for placing the semi-finished battery is increased.

[0009] Furthermore, the control unit is connected to the transport line to obtain the vibration amplitude of the initial transport line under the condition that the inclined angle is greater than or equal to the preset first angle and less than the preset second angle. If the vibration amplitude is greater than or equal to the preset vibration amplitude, the placement adsorption pressure of the suction unit at the preset height of the semi-finished battery from the transport line is increased.

[0010] Furthermore, the control unit is connected to several second cameras to obtain the number of semi-finished batteries at the end position of each segment of the transport line. If the number is greater than or equal to a preset second number, the speed difference between adjacent transport lines is increased.

[0011] Furthermore, the control unit is connected to several valves to obtain the maximum difference in the number of semi-finished batteries on adjacent transport lines when the number is greater than or equal to a preset first number and less than a preset second number. If the maximum difference is greater than or equal to a preset difference, the corresponding valves above the adjacent transport lines are opened as the ion air jet area.

[0012] Furthermore, the maximum difference is the maximum value of the difference between the number of semi-finished batteries at the end of the transport line and the number at the end of the adjacent previous transport line segment.

[0013] Furthermore, the vibration amplitude is the absolute value of the difference between the height of the midpoint of the lower surface edge of the semi-finished battery in the initial base image acquired at the end of the unit acquisition time of the first camera and the height at the beginning of the unit acquisition time.

[0014] Furthermore, the inclined angle is the acute angle between the line connecting the midpoints of the upper and lower surface edges of the semi-finished battery in the initial base image, under the condition that the semi-finished battery is in contact with the starting transport line and the suction unit is detached from the semi-finished battery, and the vertical direction.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The system of the present invention, by setting up a transport unit, an absorption unit, an ion air jetting unit, a visual recognition unit, and a control unit, achieves stable transmission of alkaline batteries during the processing, overcomes the bouncing problem caused by the rotational trend and frictional abrupt changes during the absorption and release process, and the resulting chain transmission failures such as battery tipping and propagating blockage; by adjusting the tipping tendency of semi-finished batteries before transportation and the retention tendency during transportation, the stability and continuity of battery transportation are increased, the risk of production interruption caused by transportation disruptions is reduced, and the operating efficiency of the production line is improved; by setting up an ion air jetting unit, static electricity generated during transportation is reduced, avoiding the impact of static adsorption of impurities on the surface quality of the batteries; by setting up a visual recognition unit, the battery tilt angle is identified to determine the initial posture stability of the batteries after placement; by identifying the number of batteries at the end of each transport line segment, the risk of blockage is detected; and the control unit adjusts the horizontal tangential speed of the absorption unit or adjusts the placement and adsorption pressure based on the identification information. For the problem of quantity retention that may occur during transportation, the speed difference between adjacent transport lines or the ion air jetting area is adjusted, thereby improving the operational stability of the battery processing production line.

[0016] Furthermore, the system of the present invention compensates for the rotational tendency caused by the torque generated when the battery is released due to the transition from static friction to sliding friction by adjusting the horizontal tangential speed of the suction unit to place the semi-finished battery: when the tilt angle is detected to be greater than or equal to a preset second angle, the horizontal tangential speed is increased so that the battery has an initial velocity that matches the surface movement of the transport line when it is released, thereby offsetting the rotational torque caused by relative sliding, reducing the attitude deviation of the battery after landing, suppressing the occurrence of tipping tendency, and improving the success rate and positioning accuracy of single placement.

[0017] Furthermore, the system of the present invention increases the placement and adsorption pressure of the suction unit according to the vibration amplitude of the initial transport line, so that the action of the suction mechanism when releasing the battery reduces the vibration of the battery falling due to the transition between static friction and dynamic friction, weakening the adsorption adhesion of the suction cup to the battery. Since the release impact force is greatly reduced, even if there is vibration of the conveyor belt, the battery will not bounce significantly, thereby effectively maintaining the stability of its upright posture, and reducing the impact rebound and secondary bounce phenomenon caused by rigid release; at the same time, it reduces the risk of pressure damage to the surface of the outer shell.

[0018] Furthermore, the system described in this invention addresses the congestion caused by local battery accumulation by adjusting the speed difference between adjacent transport lines. When the number of batteries at the end of a certain transport line reaches or exceeds a preset second number, the speed of the transport line is increased to form a stretching transport gradient, accelerating material dispersal and preventing congestion from spreading. Moreover, the instantaneous impact force of the tiny vibrations generated by the resonance deviation after increasing the speed difference disrupts the static friction balance formed between the batteries due to accumulation. The downstream section adjacent to this point will simultaneously perform a short-term acceleration, forming a pulling force on the batteries, quickly drawing the loosened batteries in and breaking the congestion propagation chain.

[0019] Furthermore, the system of the present invention determines the ion air jetting area based on the maximum difference in the number of batteries between adjacent transport lines. Due to the inconsistency in start-stop rhythm or the difference in processing rhythm between different transport sections, the material distribution is uneven and local stacking is induced, which leads to an increase in static electricity generated by friction between the battery surface and the battery or transport line. By applying ion air, the static adsorption and micro-adhesion effect between batteries are broken by airflow disturbance, thereby reducing the friction coefficient between the transport belt surface and the battery shell, promoting battery separation and assisting its smooth transition to the next transport line. This makes it easier for the battery to slide when squeezed by subsequent batteries, thereby increasing the efficiency of battery transport.

[0020] Furthermore, the system described in this invention utilizes a zoned ion air jet structure formed by the combination of an ion fan and multi-segment controllable valves to achieve on-demand directional purging, avoiding energy waste and airflow interference caused by continuous jetting of the production line; the ion air only acts on key blockage points, thereby increasing the stability of the transportation environment.

The present invention provides an alkaline battery processing production line, comprising: A transport unit, used to transport semi-finished batteries from one processing station to the next adjacent processing station, includes several transport lines; An aspiration unit, connected to the transport unit, is used to place the semi-finished battery on the initial transport line; Ion wind jetting unit, used to jet ion wind onto the transport unit; A visual recognition unit, connected to the transport unit, is used to acquire the basic image and basic transport image of the semi-finished battery respectively, and to identify the tilt angle of the semi-finished battery in the initial basic image and the vibration amplitude of the initial transport line, as well as the number of semi-finished batteries at the end position of a single transport line in the basic transport image. A control unit, connected to the transport unit, the suction unit, the ion air jetting unit, and the visual recognition unit, is used to determine a first retention adjustment mode for the semi-finished batteries based on the number of semi-finished batteries and a second retention adjustment mode based on the inclination angle of the semi-finished batteries. The first retention adjustment mode includes adjusting the speed difference between adjacent transport lines or determining the ion air jetting area based on the maximum difference in the number of semi-finished batteries in adjacent transport lines. The second retention adjustment mode includes adjusting the horizontal tangential speed of the suction unit for placing the semi-finished batteries or adjusting the placement adsorption pressure based on the vibration amplitude of the initial transport line.

[0027] Specifically, semi-finished batteries are battery components that have not completed all processes during battery assembly. The assembly process of alkaline batteries includes the assembly and sealing of the positive electrode, negative electrode, separator, electrolyte, and casing. The assembly process is carried out by setting up assembly table 6.

[0028] Specifically, the semi-finished battery is cylindrical in shape.

[0029] Specifically, a single transport line includes a conveyor belt 4, a roller 5 connected to the conveyor belt 4, and a drive motor connected to the roller 5 to drive the roller 5 to rotate.

[0030] Specifically, the suction unit includes a robotic arm 7 and a suction cup 8 connected to the robotic arm 7; wherein, a rubber pad is provided on the inner side of the suction cup 8.

[0031] In practice, the system described in this invention, by setting up a transport unit, an absorption unit, an ion air jetting unit, a visual recognition unit, and a control unit, achieves stable transport of alkaline batteries during processing, overcomes the bouncing problem caused by rotational trends and frictional abrupt changes during absorption and release, and the resulting chain of transport failures such as battery tipping and propagating blockages. By adjusting the tipping tendency of semi-finished batteries before transport and the retention tendency during transport, the stability and continuity of battery transport are increased, the risk of production interruption due to poor transport is reduced, and the operating efficiency of the production line is improved. By setting up an ion air jetting unit, static electricity generated during transport is reduced, avoiding the impact of static adsorption of impurities on the surface quality of the batteries. By setting up a visual recognition unit, the battery tilt angle is identified to determine the initial posture stability of the batteries after placement. By identifying the number of batteries at the end of each transport line segment, the risk of blockage is detected. Based on the identification information, the control unit adjusts the horizontal tangential speed of the absorption unit or adjusts the placement and adsorption pressure. For the problem of quantity retention that may occur during transport, the speed difference between adjacent transport lines or the ion air jetting area is adjusted, thereby improving the operational stability of the battery processing production line.

[0032] Specifically, the visual recognition unit includes: The first camera 3 is set on the starting transport line to capture the initial basic image of the semi-finished battery on the starting transport line; Several second cameras 9 are set at the end of several sections of the transport line that are not the starting transport line, in order to capture the basic transport images of the semi-finished battery.

[0033] Specifically, the first camera 3 and the second camera 9 are industrial cameras.

[0034] Specifically, the visual recognition unit also includes an image processor that is used with the first camera 3 and several second cameras 9 to identify the tilt angle of the semi-finished battery in the initial base image and the vibration amplitude of the initial transport line, as well as the number of semi-finished batteries at the end position of a single transport line in the base transport image.

[0035] Specifically, the outline of the semi-finished battery is identified and its central axis is fitted using an edge detection algorithm; the coordinates of the midpoint of the lower surface edge of the battery are extracted from consecutive frame images, and the absolute value of the displacement of the midpoint coordinates within a unit time period is used as the vibration amplitude; the vibration amplitude is calculated using the inter-frame difference method. The unit duration is 0.1s.

[0036] Specifically, the ion wind jetting unit includes: Ion air duct 1 is disposed above the transport line to spray ion air onto the semi-finished battery on the transport line. An ion fan, which is connected to the ion duct 1, is used to spray ion air into the ion duct 1. Several valves 2 are connected to the ion channel 1 to control the opening state of the corresponding ion channel 1 section.

[0037] Specifically, the control unit is connected to the first camera 3 to obtain the tilt angle. If the tilt angle is greater than or equal to a preset second angle, the horizontal tangential speed of the suction unit for placing the semi-finished battery is increased.

[0038] Specifically, the horizontal tangential velocity is the component of the velocity of the suction cup 8 moving in the direction of the conveyor belt 4 at the moment when the robotic arm 7 drives the suction cup 8 to release the semi-finished battery.

[0039] In practice, the set transmission speed of conveyor belt 4 is 0.5 m / s, and the set horizontal tangential speed of robotic arm 7 is 0.5 m / s.

[0040] Specifically, under the conditions that the diameter of the semi-finished battery is 14mm, the height is 50mm, and the speed at which the conveyor line receives batteries does not exceed 5s / battery, the general range of the preset first included angle is [0.1°, 1.5°], the preferred embodiment of the preset first included angle is 1.2°, the general range of the preset second included angle is [2°, 5°], and the preferred embodiment of the preset second included angle is 4°.

[0041] Those skilled in the art will understand that the range of preset first included angle and preset second included angle provided in this embodiment, as well as the preferred embodiment, are the values ​​that best address the technical problem solved by the technical solution of the present invention, under the conditions that the diameter of the semi-finished battery is 14mm, the height is 50mm, and the speed at which the transport line receives batteries does not exceed 5s / battery. In actual applications or experiments, those skilled in the art can make adaptive adjustments to the preset first included angle and preset second included angle according to the actual application environment and application scenario.

[0042] In practice, if the difference between the inclined angle and the preset second angle exceeds 1°, the horizontal tangential velocity increases by 0.01 m / s. For example, if the difference between the inclined angle and the preset second angle is 3°, the horizontal tangential velocity increases to 0.5 m / s + 3 × 0.01 m / s = 0.53 m / s.

[0043] In practice, the system of the present invention compensates for the rotational tendency caused by the torque generated when the battery is released due to the transition from static friction to sliding friction by adjusting the horizontal tangential speed of the suction unit to place the semi-finished battery: when the tilt angle is detected to be greater than or equal to a preset second angle, the horizontal tangential speed is increased so that the battery has an initial velocity that matches the surface movement of the transport line when it is released, thereby offsetting the rotational torque caused by relative sliding, reducing the attitude deviation of the battery after landing, suppressing the occurrence of tipping tendency, and improving the success rate and positioning accuracy of single placement.

[0044] Specifically, the control unit is connected to the transport line and is used to obtain the vibration amplitude of the initial transport line under the condition that the inclined angle is greater than or equal to the preset first angle and less than the preset second angle. If the vibration amplitude is greater than or equal to the preset vibration amplitude, the placement adsorption pressure of the suction unit at the preset height of the semi-finished battery from the transport line is increased.

[0045] Specifically, the placement adsorption pressure is the vacuum negative pressure value between the inner surface of the suction cup 8 and the contact surface of the semi-finished battery at the moment of release of the semi-finished battery.

[0046] Specifically, under the conditions that the diameter of the semi-finished battery is 14mm, the height is 50mm, the speed at which the conveyor line receives batteries does not exceed 5s / battery, the conveyor belt 4 is a polyurethane synchronous belt, and the static tension of the conveyor belt 4 is 40N, the general range of the preset vibration amplitude is [0.2mm, 2mm], the preferred embodiment of the preset vibration amplitude is 1mm, the general range of the preset height is [8mm, 20mm], and the preferred embodiment of the preset height is 10mm.

[0047] In practice, the suction unit carries the battery to the top of the transport line. The suction unit descends vertically until the distance between the lower surface of the semi-finished battery and the surface of the conveyor belt 4 reaches a preset height of 10mm. The suction unit pauses at the preset height for no more than 2 seconds, and then places the battery according to the placement adsorption pressure. For batteries of different sizes or weights, those skilled in the art can adjust the preset height.

[0048] Those skilled in the art will understand that the range of preset vibration amplitudes and preferred embodiments provided in this embodiment are the values ​​that best address the technical problem solved by the present invention, under the conditions that the diameter of the semi-finished battery is 14mm, the height is 50mm, the speed at which the transport line receives batteries does not exceed 5s / battery, the conveyor belt 4 is a polyurethane synchronous belt, and the static tension of the conveyor belt 4 is 40N. In actual applications or experiments, those skilled in the art can make adaptive adjustments to the preset vibration amplitudes according to the actual application environment and application scenario.

[0049] In practice, if the difference between the vibration amplitude and the preset vibration amplitude exceeds 0.1 mm, the placement and adsorption pressure will increase by 1 kPa. For example, if the difference between the vibration amplitude and the preset vibration amplitude is 0.4 mm and the current placement and adsorption pressure is -20 kPa, then the placement and adsorption pressure will increase to -20 kPa + 1 kPa × 4 = -16 kPa.

[0050] In practice, the system of the present invention increases the placement and adsorption pressure of the suction unit according to the vibration amplitude of the initial transport line. This reduces the vibration of the battery falling caused by the transition from static friction to dynamic friction when the suction mechanism releases the battery, thus weakening the adsorption adhesion of the suction cup 8 to the battery. Due to the significant reduction in release impact force, even if the conveyor belt 4 vibrates, the battery will not bounce significantly, thereby effectively maintaining the stability of its upright posture and reducing the impact rebound and secondary bounce phenomenon caused by rigid release. At the same time, it reduces the risk of pressure damage to the surface of the outer shell.

[0051] Specifically, the control unit is connected to several second cameras 9 to obtain the number of semi-finished batteries at the end position of each segment of the transport line. If the number is greater than or equal to a preset second number, the speed difference between adjacent transport lines is increased.

[0052] Specifically, the speed difference is the difference between the transport speed of the downstream transport line and the transport speed of the upstream transport line of two adjacent transport lines.

[0053] Specifically, under the condition that the design capacity of each transport line is no more than 35 semi-finished batteries arranged continuously, the general range of the preset first quantity is [4, 6], the preferred embodiment of the preset first quantity is 5, the general range of the preset second quantity is [9, 12], and the preferred embodiment of the preset second quantity is 10.

[0054] Those skilled in the art will understand that the range of preset first quantity and preset second quantity provided in this embodiment, as well as the preferred embodiment, are the values ​​that best address the technical problem solved by the technical solution of the present invention, under the condition that the design capacity of each transport line is no more than 35 semi-finished batteries arranged continuously. In actual applications or experiments, those skilled in the art can make adaptive adjustments to the preset first quantity and preset second quantity according to the actual application environment and application scenario.

[0055] In practice, for every difference of one between the number of semi-finished batteries and the preset second quantity, the speed difference increases by 0.05 m / s. For example, if the difference between the number of semi-finished batteries and the preset second quantity is two, and the current speed difference is 0, then the speed difference increases to 0.05 m / s × 2 = 0.1 m / s.

[0056] In practice, the system described in this invention addresses the congestion caused by local battery accumulation by adjusting the speed difference between adjacent transport lines. When the number of batteries at the end of a certain transport line reaches or exceeds a preset second number, the speed of the transport line is increased to form a stretching transport gradient, accelerating material dispersal and preventing congestion from spreading. Furthermore, the instantaneous impact force of the tiny vibrations generated by the resonance deviation after increasing the speed difference disrupts the static friction balance formed between the batteries due to accumulation. The downstream section adjacent to this point will simultaneously perform a short-term acceleration, forming a pulling force on the batteries, quickly drawing the loosened batteries in and breaking the congestion propagation chain.

[0057] Specifically, the control unit is connected to several valves 2 to obtain the maximum difference in the number of semi-finished batteries on adjacent transport lines when the number is greater than or equal to a preset first number and less than a preset second number. If the maximum difference is greater than or equal to a preset difference, the corresponding valves 2 above the adjacent transport lines are opened as the ion air jet area.

[0058] Specifically, under the condition that the surface dynamic friction coefficient of the conveyor belt 4 is 0.4, the general range of the preset difference amount is [1, 5], and the preferred embodiment of the preset difference amount is 3.

[0059] Those skilled in the art will understand that the selectable range of the preset difference amount and the preferred embodiment provided in this embodiment are the values ​​that are most effective in solving the technical problem of the present invention under the condition that the surface dynamic friction coefficient of the conveyor belt 4 is 0.3. In actual applications or experiments, those skilled in the art can make adaptive adjustments to the preset difference amount according to the actual application environment and application scenario.

[0060] Specifically, the maximum difference is the maximum value of the difference between the number of semi-finished batteries at the end of the transport line and the number at the end of the adjacent previous transport line segment.

[0061] Specifically, the vibration amplitude is the absolute value of the difference between the height of the midpoint of the lower surface edge of the semi-finished battery in the initial base image acquired at the end of the first camera's 3-unit acquisition time and the height at the beginning of the unit acquisition time.

[0062] Specifically, the inclined angle is the acute angle between the vertical central axis of the semi-finished battery and the vertical direction in the initial base image, under the condition that the semi-finished battery is in contact with the initial transport line and the suction unit is detached from the semi-finished battery.

[0063] Specifically, the vertical central axis is the line connecting the midpoint of the upper surface edge and the midpoint of the lower surface edge of the semi-finished battery.

[0064] In practice, the system of this invention determines the ion air jetting area based on the maximum difference in the number of batteries between adjacent transport lines. Due to the inconsistency in start-stop rhythm or the difference in processing rhythm between different transport sections, the material distribution is uneven and local stacking is induced, which leads to an increase in static electricity generated by friction between the battery surface and the battery or transport line. By applying ion air, the static adsorption and micro-adhesion effect between batteries are broken by airflow disturbance, thereby reducing the friction coefficient between the transport belt surface and the battery shell, promoting battery separation and assisting its smooth transition to the next transport line. This makes it easier for the battery to slide when squeezed by subsequent batteries, thereby increasing the efficiency of battery transport.

[0065] In practice, the system described in this invention uses a partitioned ion air jet structure formed by the ion fan and the multi-segment controllable valve 2 to achieve on-demand directional purging, avoiding energy waste and airflow interference caused by continuous jetting of the production line; the ion air only acts on key blockage points, thereby increasing the stability of the transportation environment.

[0066] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
