Description

Technical Field

[0001] The present invention relates to the field of battery processing, and particularly to an automatic printing system and printing method for battery insulating films. Background Art

[0002] In the traditional battery production process, manual or mechanical methods are usually used to wrap the insulating film around the battery case. During the wrapping process, the insulating film is easily cut by the edges and corners of the battery, or bulges at the edges and corners due to problems with the wrapping process. Eventually, during storage and transportation, the insulating film is easily damaged, resulting in the exposure of the battery case, which increases the risks that may occur during the use of the battery. At the same time, the traditional film wrapping process is complex, the product yield is low, and there are many defects. When producing batteries of different models, flexible conversion cannot be carried out, it is difficult to carry out mixed-line production, and the production efficiency is low.

[0035] Second, an automatic printing method for battery insulating films is proposed, which is applied to any one of the battery insulating film automatic printing systems in the foregoing technical solutions, and includes:

[0036] Identify the size of the battery to be processed on the battery transportation module, obtain a model mark according to the size, or search for the model mark in a preset database. Different model marks correspond to different battery processing parameters.

[0037] Synchronize the model mark to the battery transportation module, the magnetic levitation track, and each battery processing area.

[0038] The battery transportation module carries the battery to be processed along the magnetic levitation track through the surface texturing area to perform a surface texturing operation on a preset area of the battery to be processed.

[0039] The battery transportation module carries the battery to be processed along the magnetic levitation track through the cleaning area, performs a process inspection on the battery to be processed, identifies the preset area of the battery to be processed that has undergone texturing treatment, and performs a plasma cleaning operation on the preset area of the battery to be processed that passes the process inspection.

[0040] The battery transportation module carries the battery to be processed along the magnetic levitation track through the surface printing area, performs a process inspection on the battery to be processed, identifies the preset area of the battery to be processed that has been cleaned, and performs an insulating film printing and pre-curing operation on the preset area of the battery to be processed that passes the process inspection in the surface printing area.

[0041] The battery to be processed is transported to the inspection and confirmation area through the magnetic levitation track, and final curing is performed on the battery to be processed, and the processing result of the battery to be processed is detected.

[0042] In some specific embodiments, synchronizing the model mark to the battery transportation module, the magnetic levitation track, and each battery processing area includes:

[0043] Set the model mark for the corresponding battery transportation module through the main control module.

[0044] Send the model mark and the battery processing parameters corresponding to the model mark to the maglev track, the surface texturing area, the cleaning area, and the surface printing area;

[0045] The maglev track adjusts the magnitude of the current frequency according to the battery processing parameters, and / or the adjusting device of the battery transport module adjusts the width and / or length of the battery slot according to the battery processing parameters;

[0046] Before the battery transport module enters each battery processing area, identify and update the model mark of the corresponding battery transport module;

[0047] The laser in the surface texturing area adjusts the texturing processing duration, the laser range, and / or the laser intensity, and / or the distance between the laser and the first conveying device according to the latest battery processing parameters;

[0049] The printing assembly in the surface printing area adjusts the printing duration, and / or the printing range, and / or the printing intensity, and / or the pre-curing duration, and / or the pre-curing range, and / or the pre-curing intensity according to the latest battery processing parameters;

[0050] The battery transport module adjusts the moving speed of entering the surface texturing area, the cleaning area, and the surface printing area along the maglev track respectively according to the texturing processing duration, the cleaning processing duration, the printing duration, and the pre-curing duration.

[0051] In a specific embodiment, multiple battery transport modules move along the maglev track, successively driving the batteries to be processed into the surface texturing area, the cleaning area, and the surface printing area, so as to successively process the batteries to be processed. In practical applications, the processing durations of different battery processing areas for the batteries to be processed are quite different. By synchronizing the battery processing parameters with each battery processing area through the main control module, the moving speed of each battery transport module between different battery processing areas can be further adjusted flexibly.

[0052] In practical applications, there are situations where different batches of batteries to be processed are handed over during production, which will result in different battery transport modules carrying different models of batteries to be processed. When there are battery transport modules carrying different models of batteries to be processed running on the same maglev track, the main control module respectively obtains the battery processing parameters of different models of batteries to be processed. The main control module sets model marks for different battery processing modules according to different battery processing parameters, and synchronizes different battery processing parameters to different battery processing areas.

[0053] In some specific embodiments, it further includes at least one induction detection unit connected to the main control module. The induction detection unit includes a vision sensor and / or an infrared sensor; the induction detection unit is arranged at a position close to each battery processing area for identifying the model mark of the battery transport module entering the battery processing area.

[0054] In a specific embodiment, induction detection units are respectively arranged at positions close to the entrances of the surface texturing area, cleaning area, and surface printing area in the battery processing area. When the battery transport module carries the battery to be processed and is about to enter the corresponding battery processing area, the induction detection unit detects the model mark set on the main control module of the battery transport module, and the induction detection unit further synchronizes the latest identified model mark to the corresponding battery processing area. The battery processing area then makes corresponding adaptability adjustments according to the obtained latest model mark.

[0055] Thus, it can better adapt to special situations such as when each battery processing module processes a small number of different models of batteries to be processed in multiple batches at the same time, adapt to the mixed-line production of multi-model batteries, and can effectively improve the flexibility of the system.

[0056] In a specific embodiment, while the induction detection unit identifies the model mark of the battery transport module, it also performs process detection on the battery to be processed in the battery processing module.

[0057] In some specific embodiments, the process detection includes:

[0058] Detecting whether the battery to be processed in the current battery processing area meets the preset process requirements according to the processing process executed in the current battery processing area;

[0059] The process result detection for the battery to be processed includes:

[0060] Detecting whether the printing uniformity on the surface of the battery to be processed reaches the preset value, and setting a screening label for the battery slot where the battery to be processed with the printing uniformity not reaching the preset value is located;

[0061] Detecting whether the thickness of the battery to be processed reaches the preset value, and setting a screening label for the battery slot where the battery to be processed not reaching the preset value is located;

[0062] Detecting whether the inkjet information of the battery to be processed is qualified, and setting a screening label for the battery slot where the unqualified battery to be processed is located;

[0063] Sending the screening label to the screening mechanism; the screening mechanism identifies the screening label and removes the battery to be processed on the battery slot with the screening label from the battery slot.

[0064] Beneficial effects: The present application provides an automatic printing system and a printing method for battery insulation films. By using a magnetic levitation track to transport the batteries to be processed, the transportation efficiency of materials can be effectively improved. Further, by cooperating with the surface roughening area, cleaning area, and surface printing area in the battery processing area, the printing process of the battery surface insulation film can be efficiently and automatically completed, greatly improving the processing efficiency of the battery. Furthermore, the printing method is applicable to the mixed-line production of different models of batteries. When processing different models of batteries, there is no need to spend time manually resetting the battery processing parameters, which has strong flexibility and a high level of automation.

[0089] Embodiment 1

[0090] Embodiment 1 of the present application discloses an automatic printing system for battery insulating films, and the specific solution is as follows:

[0091] An automatic spraying system for battery insulation film, comprising: a main control module 1, a first conveying device 2 communicatively connected to the main control module 1, and a battery processing area, the battery processing area including a surface texturing area 4, a cleaning area 5, and a surface spraying area 6;

[0092] The first conveying device 2 includes at least one magnetic levitation track 21, and at least one battery transportation module 22 is arranged on the magnetic levitation track 21; a plurality of battery slots 23 for placing the battery to be processed 10 are formed on the battery transportation module 22;

[0093] An adjusting device 24 is arranged on the battery slot 23 for adjusting the width and / or length of the battery slot 23 according to the battery processing parameters of the battery to be processed 10 obtained by the main control module 1; specifically, the battery transportation module 22 is as Figure 7 shown.

[0094] The magnetic levitation track 21 sequentially passes through the surface texturing area 4, the cleaning area 5, and the surface spraying area 6, and the battery transportation module 22 is used to move along the magnetic levitation track 21 to drive the battery to be processed 10 through the surface texturing area 4, the cleaning area 5, and the surface spraying area 6, and the overall structure is as Figure 1 , Figure 2 and Figure 3 shown.

[0095] In a specific embodiment, the magnetic levitation track 21 includes a track member, a first engaging member 211 arranged along the track member and protruding from the surface of the track member in a preset first direction, and a second engaging member 212 protruding from the surface of the track member in a preset second direction, wherein an included angle is formed between the first direction and the second direction. A fastening member 221 for cooperating with the first engaging member 211 and the second engaging member 212 is arranged on one side of the battery transportation module 22 facing the magnetic levitation track 21.

[0096] In a specific embodiment, the first direction is parallel to the plane where the track member is located, and the second direction is perpendicular to the plane where the track member is located, so that the track member can limit the movement of the battery transportation module 22 from different directions, effectively preventing the battery transportation module 22 from disengaging from the track member during transportation and ensuring the stability of the battery transportation module 22 during movement. In practical applications, the moving speed of the battery transportation module 22 on the magnetic levitation track 21 can reach 2 m / s. A magnetic structure 213 is arranged between the battery transportation module 22 and the track member corresponding to the first engaging member 211 and the second engaging member 212, so that a mutually repulsive magnetic field is formed between the battery transportation module 22 and the track member, realizing the magnetic levitation transmission of the battery transportation module 22, specifically as Figure 4 , Figure 5 and Figure 6 shown.

[0097] The first direction is asFigure 4 and Figure 6 as shown by direction A in Figure 4 and Figure 6 direction B shown in

[0098] By providing engaging members protruding in different directions, the battery transport module 22 can be engaged with the maglev track 21 from multiple directions, further improving the stability of the movement of the battery transport module 22 on the maglev track 21.

[0099] In some specific embodiments, a cylindrical surface texturing module 41 and / or an end surface texturing module 42 are provided in the surface texturing area 4;

[0100] The cylindrical surface texturing module 41 includes a first frame body 411, a first moving module 412 and a laser 413; the laser 413 is movably connected to the first frame body 411 through the first moving module 412, and the laser 413 is disposed at a position corresponding to above the maglev track 21;

[0101] The first moving module 412 is used to drive the laser 413 to approach or move away from the cylindrical surface of the battery 10 to be processed in the battery transport module 22;

[0102] The end surface texturing module 42 includes a second frame body, a second moving module and a laser 413; the end surface laser 413 is disposed on one side or corresponding two sides in the extending direction of the maglev track 21;

[0103] The laser module is movably connected to the second frame body through the second moving module; the second moving module is used to drive the end surface laser 413 to approach or move away from the end surface of the battery 10 to be processed in the battery transport module 22.

[0104] In practical applications, the first moving module 412, and / or the second moving module, and / or the third moving module 62 may include a vertical movement mechanism for driving the laser 413 in the vertical direction and a horizontal movement mechanism for driving the laser 413 in the horizontal direction, whereby the relative position between the laser 413 and the battery 10 to be processed on the battery transport module 22 can be adjusted flexibly.

[0105] In some specific embodiments, a third frame body 61, a third moving module 62 and a printing assembly 63 are provided in the surface printing area 6;

[0106] At least one set of printing assemblies 63 is linearly movable and / or rotatably connected to the third frame body 61 through the third moving module 62; the printing assembly 63 includes a printing head 65 and a pre-curing mechanism 66 disposed adjacent to each other;

[0107] A printing processing cover 64 is connected to part or all of the printing components 63. An opening is provided on the printing processing cover 64 for the battery transportation module 22 to enter. The printing head 65 and the pre-curing mechanism 66 are exposed relative to the inner side wall of the printing processing cover 64.

[0108] The printing head 65 is used to print on the cylindrical surface and / or end surface of the battery 10 to be processed entering the printing processing cover 64. The pre-curing mechanism 66 is used to pre-cure the battery 10 to be processed after printing in the printing processing cover 64.

[0109] Specifically, according to whether the position of the printing head 65 in the printing component 63 corresponds to the cylindrical surface or the end surface of the battery 10 to be processed, the surface printing area 6 can be divided into a cylindrical surface printing module 67 and an end surface printing module 68, as specifically shown in Figure 11 the end surface printing module 68 and Figure 12 the cylindrical surface printing module 67 shown.

[0110] By arranging the pre-curing mechanism 66 near the printing head 65, it is possible to immediately perform a surface pre-curing after the printing head 65 prints a part of the area of the battery 10 to be processed, enabling a preliminary cross-linked structure to be quickly formed on the surface of the battery 10 to be processed and preventing the coating from being washed away or deformed during subsequent printing. In practical applications, the printing head 65 can be adjusted in angle relative to the printing processing cover 64. The battery 10 to be processed passes through multiple printing heads 65 and the pre-curing mechanism 66 in sequence, enabling multiple times of printing and pre-curing. The thickness of the coating for each printing can be precisely controlled. For areas and structures on the surface of the battery 10 to be processed that are difficult to complete coating in one pass, different printing heads 65 can be adjusted to different angles to complete the complete coverage of the surface of the battery 10 to be processed, improving the film layer integrity of the insulating film. By stacking multiple insulating films and performing staged curing, the insulation withstand voltage strength of the battery can be effectively improved.

[0111] In practical applications, the printing component 63 further includes at least one material bin communicating with the printing head 65, and the material bin is used to store the printing material for the battery insulating film.

[0112] In some specific embodiments, as shown in Figure 10 , a fixed frame 51 and a plasma spray gun 52 are provided in the cleaning area 5;

[0113] Part or all of the fixed frame 51 is arranged above the magnetic levitation track 21. One end of the plasma spray gun 52 is movably arranged on the fixed frame 51, and the other end is arranged above the magnetic levitation track 21 or on both sides of the magnetic levitation track 21, and is used to perform plasma cleaning operations on the cylindrical surface and / or side surface of the battery 10 on the magnetic levitation track 21.

[0114] By using plasma to treat the surface of the battery 10 to be treated, dust and organic matter on the battery surface can be efficiently removed, and the surface activity and adhesion of the battery can be improved. Plasma can evenly cover complex curved surfaces and is suitable for surface treatment of batteries. The treatment intensity and treatment area can be precisely controlled to meet the cleaning requirements of batteries 10 to be treated of different models and shapes. At the same time, plasma cleaning does not require the use of chemical solvents, thus avoiding chemical residues and wastewater treatment problems that may be caused by traditional cleaning methods, which is in line with the trend of green production.

[0115] In a specific embodiment, the modules in the cleaning area 5 can be divided into a cylindrical cleaning module 53 for the cylindrical surface of the battery 10 to be processed and an end surface cleaning module 54 for the end surface of the battery 10 to be processed according to the orientation position of the plasma spray gun, so as to clean the cylindrical surface and end surface of the battery 10 to be processed from different directions respectively.

[0142] Among them, the schematic diagrams of specific steps are as Figure 18 shown. In practical applications, the battery that passes through the inspection and confirmation area and completes the processing result detection has successfully completed the processing procedure of automatic insulating film printing and can be processed in the next step for other procedures.

[0143] Among them, the battery processing parameters may include the processing requirements of the battery 10 to be processed corresponding to each battery processing area, such as the surface texturing area, texturing degree, thickness of the printed insulating film, and printing duration, etc.

[0144] In some specific embodiments, as Figure 19 shown, step S200 specifically includes:

[0145] S210. The main control module 1 sets a model mark for the corresponding battery transportation module 22;

[0146] S220. Send the battery processing parameters corresponding to the model mark and the model mark to the maglev track 21, the surface texturing area 4, the cleaning area 5, and the surface printing area 6;

[0147] S230. The maglev track 21 obtains the corresponding battery processing parameters according to the model mark, adjusts the magnitude of the current frequency according to the battery processing parameters, and / or the adjusting device 24 of the battery transportation module 22 adjusts the width and / or length of the battery slot 23 according to the battery processing parameters;

[0148] S240. Before the battery transportation module 22 enters each battery processing area, identify and update the model mark of the corresponding battery transportation module 22.

[0149] S250. The laser 413 in the surface texturing area 4 adjusts the texturing processing duration, laser range, and / or laser intensity, and / or the distance between the laser 413 and the first conveying device 2 according to the latest battery processing parameters.

[0150] S260. The plasma spray gun 52 in the cleaning area 5 adjusts the cleaning processing duration, cleaning range, and / or cleaning intensity, and / or the distance between the plasma spray gun 52 and the first conveying device 2 according to the latest battery processing parameters.

[0152] S280. The battery transportation module 22 adjusts the moving speed along the maglev track 21 to enter the surface texturing area 4, the cleaning area 5, and the surface printing area 6 respectively according to the texturing processing duration, the cleaning processing duration, the printing duration, and the pre-curing duration.

[0153] In a specific embodiment, the main control module 1 includes a host computer. By setting the model mark for the battery transportation module 22 through the main control module 1, the battery transportation module 22 can intelligently adjust the moving speed on the maglev track 21 according to the battery processing parameters corresponding to the model mark and the processing duration of each battery processing area. In practical applications, the moving speed of the battery transportation module 22 on the maglev track 21 can reach 2 m / s.

[0154] In a specific embodiment, multiple battery transportation modules 22 move along the maglev track 21, successively driving the battery to be processed 10 into the surface texturing area 4, the cleaning area 5, and the surface printing area 6 to successively process the battery to be processed 10. In practical applications, the processing durations of different battery processing areas for the battery to be processed 10 are quite different. By synchronizing the battery processing parameters and each battery processing area through the main control module 1, the moving speed of each battery transportation module 22 between different battery processing areas can be further flexibly adjusted.

[0155] In practical applications, there are situations where batteries 10 to be processed in different batches are handed over during the production process. This will result in different types of batteries 10 to be processed being carried on different battery transport modules 22. When battery transport modules 22 carrying different types of batteries 10 to be processed are running on the same maglev track 21, the main control module 1 respectively obtains the battery processing parameters of different types of batteries 10 to be processed. The main control module 1 sets model marks for different battery processing modules according to different battery processing parameters, and synchronizes different battery processing parameters to different battery processing areas.

[0156] In some specific embodiments, it further includes at least one induction detection unit 11 connected to the main control module 1. The induction detection unit 11 includes a vision sensor and / or an infrared sensor; the induction detection unit 11 is arranged at a position close to each battery processing area for identifying the model mark of the battery transport module 22 entering the battery processing area. Specifically, the installation position of the induction detection unit 11 is as Figure 14 shown.

[0157] In a specific embodiment, induction detection units 11 are respectively arranged at positions close to the entrances of the surface texturing area 4, the cleaning area 5, and the surface printing area 6 in the battery processing area. When the battery transport module 22 carries the battery 10 to be processed and is about to enter the corresponding battery processing area, the induction detection unit 11 detects the model mark set by the main control module 1 on the battery transport module 22. The induction detection unit 11 further synchronizes the newly identified model mark to the corresponding battery processing area, and the battery processing area makes corresponding adaptive adjustments to the operating characteristics of each component in the processing area according to the obtained latest model mark.

[0158] Thus, it can better adapt to special situations such as various battery processing modules simultaneously processing a small number of different types of batteries 10 in multiple batches, adapt to the mixed-line production of multi-type batteries, and can effectively improve the flexibility of the system. Further, it can also reduce the time consumed during the connection and processing of different batches and different types of batteries.

[0159] In a specific embodiment, while the induction detection unit 11 identifies the model mark of the battery transport module 22, it also performs process detection on the battery 10 to be processed in the battery processing module.

[0160] In some specific embodiments, the process detection includes:

[0161] Detecting whether the battery 10 to be processed in the current battery processing area meets the preset process requirements according to the processing process executed in the current battery processing area;

[0162] In a specific embodiment, a screening mechanism is provided near each battery processing area. When the battery 10 to be processed in the battery processing area does not meet the preset process requirements, the screening mechanism obtains the position of the battery slot 23 where the battery 10 to be processed that does not meet the preset process requirements is located from the induction detection unit 11, so as to remove the battery 10 to be processed from the battery slot 23 of the battery transportation module 22. Specifically, each battery slot 23 in the battery transportation module 22 corresponds to a battery slot 23 number, and the screening mechanism can locate the battery 10 to be processed in the battery slot 23 through the battery slot 23 number.

[0163] As Figure 20 shown, the detection of the processing result of the battery 10 to be processed includes:

[0164] S410. Detect whether the printing uniformity on the surface of the battery 10 to be processed reaches a preset value, and set a screening label for the battery slot 23 where the battery 10 to be processed with the printing uniformity not reaching the preset value is located;

[0165] S420. Detect whether the thickness of the battery 10 to be processed reaches a preset value, and set a screening label for the battery slot 23 where the battery 10 to be processed that does not reach the preset value is located;

[0166] S430. Detect whether the spray code information of the battery 10 to be processed is qualified, and set a screening label for the battery slot 23 where the unqualified battery 10 to be processed is located;

[0167] S440. Send the screening label to the screening mechanism; the screening mechanism identifies the screening label and removes the battery 10 to be processed on the battery slot 23 with the screening label from the battery slot 23.

[0168] By detecting the spray code information of the battery 10 to be processed and setting a screening label for the battery slot 23 where the unqualified battery 10 to be processed is located, the position of the problematic battery 10 to be processed can be accurately located, enabling the screening mechanism to accurately and quickly identify and remove the battery 10 to be processed. In practical applications, the screening mechanism can be a manipulator or a mechanical clamping mechanism, or it can be the same grasping mechanism as the material transfer unit. At the same time, the screening mechanism can quickly adjust its clamping size according to the model label of the battery 10 to be processed to cooperate with the battery 10 to be processed.

[0169] This embodiment provides a method for spraying an insulating film of a battery. By using a magnetic levitation track to transport the battery to be processed, the transportation efficiency of materials can be effectively improved. By flexibly setting the model labels of the batteries to be processed and the corresponding battery processing parameters, the transportation of the battery transportation module can cooperate with the surface texturing area, cleaning area, and surface spraying area in the battery processing area, which can greatly improve the production and processing efficiency of the battery. Further, it is more suitable for the mixed-line production of different models of batteries and has strong flexibility.
