Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of battery production, and in particular to a battery insulating film preparation system and preparation method. Background Art
[0002] During the battery production process, an insulating film is usually required on the outer surface of the battery. The insulating film is usually a thin film material with good battery insulation performance and chemical stability. It can prevent the battery from directly contacting with external metal substances or other conductive substances to a certain extent, thereby reducing the risk of battery short circuit and improving the safety and stability of the battery.
[0003] In the prior art, the quality of insulating film preparation directly affects the safety performance of the battery. In order to obtain a good insulating film preparation effect, multiple processing is often required. A common method is to spray the battery multiple times. However, even after multiple spraying, problems such as uneven spraying of the insulating film and easy falling off of the insulating film are still prone to occur. In addition, because the preparation process of the insulating film on the outer surface of the battery is relatively complicated, the battery often needs to be transferred between multiple processing mechanisms through a conveyor line, which seriously reduces production efficiency. Due to the complexity of the processing steps, once there is a problem with the battery insulating film, it is difficult to find the cause.

[0069] Example 1
[0070] The present application embodiment proposes a battery insulation film preparation system, such as Figures 1 to 9 As shown, it includes: a loading conveyor line 1, a rotary processing line 2, a unloading conveyor line 3 and a main control unit 4;
[0071] The output end of the feeding conveyor line 1 is connected to the rotary processing line 2, so as to sequentially convey each batch of batteries to the rotary processing line 2 at a preset time interval;
[0072] The input end of the unloading conveyor line 3 is connected to the rotary processing line 2, so as to sequentially transfer each batch of batteries out of the rotary processing line 2 at a preset time interval;
[0073] The rotary processing line 2 is provided with a plurality of processing mechanisms 5 in the circumferential direction. The processing mechanisms 5 are arranged in sequence according to the sequence of the preset processing steps. The rotary processing line 2 rotates at a preset rotation angle at a preset time interval to sequentially perform the preset processing steps on the batteries of each batch conveyed to the rotary processing line 2, so that an insulating film is formed on the outer surface of the battery; wherein the batteries of adjacent batches differ by one or more processing steps;
[0074] Specifically, in some embodiments of the present application, the processing mechanism 5 includes one or any multiple of a laser texturing mechanism 51 , a plasma cleaning mechanism 52 , and a three-dimensional spraying and pre-curing mechanism 54 ;
[0075] Specifically, in some embodiments of the present application, the preset processing steps may include laser texturing, plasma cleaning, stereo spraying and pre-curing steps;
[0076] Preferably, in some embodiments of the present application, adjacent batches of batteries differ by one processing step;
[0077] It can be understood that the plurality of processing mechanisms 5 can be arranged in a clockwise direction along the circumferential direction of the rotary processing line 2 in the order of the processing steps, or can be arranged in a counterclockwise direction along the circumferential direction of the rotary processing line 2 in the order of the processing steps. The specific direction of the arrangement is closely related to the rotation direction of the rotary processing line 2.
[0078] The rotary processing line 2 integrates several processing mechanisms 5 into one, which can reduce the setting of the conveying mechanism between different processing mechanisms 5, reduce the manufacturing cost of the system, and at the same time streamline the overall structural composition, which helps to reduce the volume of the battery insulating film preparation system and avoid the bloated appearance of the battery insulating film preparation system.
[0079] The integrated setting of the rotary processing line 2 and the processing mechanism 5 also helps to optimize the connection process of the specific preparation steps of the battery insulating film. It is only necessary to drive the rotary processing line 2 multiple times at preset time intervals to complete the preparation of the insulating film. There is no need to frequently transfer batteries between different processing mechanisms 5 by setting up a conveying mechanism, which effectively shortens the overall preparation time of the insulating film. It is also possible to simultaneously process different batches of batteries, so that different batches of batteries are in different preparation steps in chronological order, further improving the preparation efficiency of the battery insulating film. Different batches of batteries are not prone to mutual influence, which also helps to maintain the consistency of the quality of the insulating films of the same batch and different batches of batteries.
[0080] The unloading conveyor line 3 is also provided with a final curing mechanism 31, which is used to perform final curing treatment on the battery transferred out of the rotary processing line 2, so as to fix the spraying effect of the insulating film formed by the rotary processing line 2, and finally complete the preparation of the battery insulating film;
[0081] The coordination between the three-dimensional spraying and pre-curing mechanism 54 and the final curing mechanism 31 can help to better control the thickness and uniformity of the insulating film preparation. The battery is first three-dimensionally sprayed by the three-dimensional spraying and pre-curing mechanism 54 to obtain a good spraying effect, so as to form an insulating film on the battery surface, so that the insulating film can evenly cover the outer surface of the battery, and then the sprayed insulating film is quickly cured and attached in time, which to a certain extent helps to avoid the flow or fall off of the liquid insulating film before drying, so that the insulating film can be stably formed; at the same time, it also helps to speed up the forming speed of the insulating film, effectively shortening the production cycle, and is a precise control of the spraying process, which can avoid uneven insulating film layers, such as being too thick or too thin.
[0082] Specifically, in some embodiments of the present application, the three-dimensional spraying and pre-curing mechanism 54 and the final curing mechanism 31 use different curing lights to enhance the curing effect.
[0083] The final curing mechanism 31, the three-dimensional spraying and the pre-curing mechanism 54 actually perform a double or multiple curing process on the insulating film, which enhances the bonding degree between the insulating film and the battery surface, improves the adhesion and durability of the insulating film, optimizes the quality of the insulating film, and helps to maintain the stability of the battery during use.
[0084] The main control unit 4 is respectively connected to the loading conveyor line 1 , the rotary processing line 2 , the unloading conveyor line 3 and each processing mechanism 5 for communication, and is used to preset the time interval and the rotation angle of the rotary processing line 2 .
[0085] Optionally, in some embodiments of the present application, the rotation time interval can be set according to the longest time consumed in each processing step; the size of the rotation angle can also be set according to the number of processing steps, processing stations 23 or processing mechanisms 5.
[0086] For example, assuming that the three-dimensional spraying and pretreatment steps take the longest time, and the time is 30 seconds, the rotation time interval can be set to 30 seconds, the preset processing steps are 6, and the number of processing stations 23 is 6, then the corresponding rotation angle can be set to 60 degrees; of course, it can also be set according to the preparation process of the battery insulating film.
[0087] Furthermore, if Figure 4 As shown, a scanning mechanism 14 and a removal mechanism 15 are provided on the feeding conveyor line 1. The scanning mechanism 14 is used to scan and identify each battery entering the feeding conveyor line 1 to determine the batch information of the battery, and send the scanning and identification results of each battery to the main control unit 4;
[0088] It can be understood that the scanning mechanism 14 is provided on the feeding conveyor line 1 to facilitate identification of battery information and tracking of the processing progress or flow direction of the battery;
[0089] Specifically, the information code on the battery, such as a barcode or a QR code, can be scanned to obtain the production date, weight, specification, batch, etc. of the product; in some embodiments of the present application, the information code is printed on the bottom surface of the battery, and the battery is horizontally placed on the loading conveyor line 1 for transportation;
[0090] The main control unit 4 is used to control the feeding conveyor line 1 to convey the batteries that have been successfully scanned and identified to the rotary processing line 2 for processing;
[0091] The main control unit 4 is also used to control the removal mechanism 15 to remove the batteries that have failed the code scanning recognition from the feeding conveyor line 1.
[0092] It can be understood that if the battery code is scanned and identified successfully, the identification information will be sent to the main control unit 4 before the processing starts, and the corresponding battery will be marked, and the corresponding information of the battery insulation film preparation will be added, such as the processing time and processing batch, so that the battery is bound to its specific position on the rotating processing line 2, which is convenient for further tracking of the battery preparation process.
[0093] If the battery code scanning and recognition fails, the subsequent insulation film preparation of the battery cannot be tracked, the production and processing process of the battery cannot be traced, and the quality and source of the battery cannot be confirmed. Therefore, it is impossible to effectively manage the quality of the battery insulation film, and the batteries that cannot be scanned and identified need to be removed from the production process;
[0094] Specifically, in some embodiments of the present application, the removal mechanism 15 can be implemented by a fork structure. Of course, there is no limitation on the specific implementation method of the removal mechanism 15.
[0095] Furthermore, the processing mechanism 5 includes one or more of a laser texturing mechanism 51, a plasma cleaning mechanism 52, a detection mechanism 53, and a three-dimensional spraying and pre-curing mechanism 54.
[0096] The detection mechanism 53 is arranged along the circumferential direction of the rotary processing line 2 and is located between the plasma cleaning mechanism 52 and the three-dimensional spraying and pre-curing mechanism 54. The detection mechanism 53 is communicatively connected to the main control unit 4;
[0097] The detection mechanism 53 is used to perform a roughening effect detection and / or a position detection on the battery, and send information of the battery whose roughening effect detection result and / or position detection result does not meet the requirements to the main control unit 4;
[0098] The main control unit 4 is used to control a preset mechanism (not shown in the figure) to remove the batteries whose texturing effect detection results do not meet the requirements from the rotary processing line 2, and to generate a record of the batteries whose texturing effect detection results do not meet the requirements;
[0099] The main control unit 4 is also used to control the clamping mechanism 231 provided at each processing station 23 on the rotary processing line 2 to adjust the position of the battery whose position detection result does not meet the requirements until the battery meets the position requirements.
[0100] The preset mechanism is used to remove the battery from the production line, and the structure may adopt a fork structure that is the same as or similar to the removal mechanism 15. Of course, there is no limitation on the specific structure of the preset mechanism.
[0101] It can be understood that a detection mechanism 53 is provided between the plasma cleaning mechanism 52 and the three-dimensional spraying and pre-curing mechanism 54, which can directly detect the roughening effect of the outer surface of the battery, determine whether the laser roughening reaches the expected quality standard or effect, and send the laser roughening effect detection result to the main control unit 4. Specifically, it can be used to detect the uniformity, smoothness or roughness of the roughening structure on the outer surface of the battery; after laser roughening, it can effectively improve the adhesion ability of the outer surface of the battery to the insulating film, thereby improving the preparation effect of the insulating film.
[0102] If the laser roughening effect does not meet expectations or requirements, it is easy to affect the adhesion of the insulating film. Through detection by the detection mechanism 53, possible production defects can be discovered in advance, the scrap rate can be reduced, and the preparation of the insulating film of these batteries can be terminated in advance, which reduces the waste of resources and also reduces the cost of later repair and backtracking.
[0103] By recording the battery information by different battery information recording devices, such as the code scanning mechanism 14 and the detection mechanism 53, different preparation links of the battery can be monitored so that a targeted processing method can be adopted when the battery is subsequently processed.
[0104] The detection mechanism 53 also detects the position of the battery. If the battery does not have a roughening quality problem but a position problem, the positional relationship between the battery and the processing mechanism 5 will also affect the preparation effect of the insulating film. The position of the processing mechanism 5 can be adjusted, or the battery position can be adjusted by the clamping mechanism 231; so that the battery reaches the expected position to better complete the subsequent spraying of the insulating film.
[0105] Furthermore, a thickness measuring device 32 is provided, which is arranged on the unloading conveyor line 3 at the rear end of the final curing mechanism 31 and is connected to the main control unit 4 for communication; the thickness measuring device 32 is used to measure the thickness of the battery after the insulating film is prepared, and send the thickness measurement result of the battery to the main control unit 4;
[0106] It can be understood that a thickness measuring device 32 is provided to measure the thickness of the battery to meet some application scenarios with strict requirements on the thickness of the battery; by measuring the thickness of the battery, the thickness of the insulating film can also be further detected. If the insulating film is too thick or too thin, it will affect the effective function of the insulating film, so it is necessary to set a reasonable insulating film thickness range;
[0107] Of course, the thickness of the insulating film can be reflected by the thickness of the battery;
[0108] The main control unit 4 is used to determine whether the battery thickness is qualified based on the thickness measurement result, control the preset mechanism (not shown in the figure) to remove the batteries with unqualified thickness measurement results from the production line, and generate records about the batteries with unqualified thickness measurement results. If the frequency or frequency of generating records exceeds the preset value, the parameters of different processing mechanisms 5 are adjusted accordingly according to the thickness information in the record.
[0109] The recorded thickness information may include the specific thickness of the battery, whether it is too thick or too thin;
[0110] Exemplarily, the main control unit 4 may further set up a queue to temporarily store these records, where too thick is indicated by a value of 0; too thin is indicated by a value of 1. When the battery thickness problems in the entire queue are all too thick or too thin, that is, when the data stored in the queue are all 0 or 1, or when the number of data of 0 or 1 in the same queue exceeds a preset value, the parameters of the processing mechanism 5 need to be adjusted;
[0111] For another example, if the battery is too thick, it is possible that the three-dimensional spraying step takes too long, and the processing time of the three-dimensional spraying and pre-curing mechanism 54 needs to be adjusted accordingly; of course, it may also be caused by other problems, which require specific analysis based on the actual problem.
[0112] The processing parameters of other processing mechanisms 5 are dynamically adjusted based on the detection results of the thickness measuring device 32, thereby optimizing the insulating film preparation process and helping to improve the quality of the insulating film.
[0113] If the battery thickness meets the requirements, the battery will be moved to the next production stage.
[0114] Furthermore, if Figure 5 and Figure 6 As shown, the rotary processing line 2 includes: a rotating platform 21, a rotating device 22 and a processing station 23;
[0115] The rotating platform 21 is connected to the output end of the rotating device 22. A plurality of processing stations 23 are sequentially arranged along the circumferential direction of the rotating platform 21. A plurality of rotatable clamping mechanisms 231 are arranged on each processing station 23. The clamping mechanisms 231 on different processing stations 23 are used to clamp and rotate batteries of different batches.
[0116] Specifically, in some embodiments of the present application, the rotating device 22 is arranged at the bottom of the rotating platform 21, and the output shaft of the rotating device 22 is coaxially arranged with the center of the rotating platform 21, so as to achieve the same rotation angle of each processing station 23, thereby enhancing the synchronization and consistency of the rotation of each processing station 23, and reducing interference factors and influencing factors during the rotation of the rotating platform 21.
[0117] More specifically, in some embodiments of the present application, the rotating device 22 is a servo motor having high dynamic response capability and rapid acceleration and deceleration capabilities to meet precise control requirements.
[0118] It can be understood that a plurality of clamping mechanisms 231 are provided on each processing station 23, so as to facilitate simultaneous processing of a plurality of batteries of the same batch, so that a plurality of batteries can be placed horizontally on the clamping mechanism 231 at the same time, which helps to improve the battery production efficiency to a certain extent;
[0119] Of course, there is no limitation on the number of the clamping mechanisms 231 , and the multiple clamping mechanisms 231 on the same processing station 23 are distributed in layers along the radial line of the rotating platform 21 .
[0120] The clamping mechanism 231 is used to clamp and rotate the battery. The clamping and rotation of the battery by the clamping mechanism 231 can more effectively adjust the position of the battery to meet the processing requirements of different processing steps. For example, when the detection mechanism 53 detects that there is a position problem with the battery, the clamping mechanism 231 can be used to adjust the position of the battery in the front-to-back and left-to-right directions on the plane of the rotating platform 21.
[0121] At least some of the processing stations 23 correspond to the processing mechanism 5 to clamp the battery for processing by the processing mechanism 5;
[0122] The main control unit 4 is connected to the rotating device 22 and the clamping mechanism 231 through communication. The rotating device 22 is used to drive the rotating platform 21 to rotate according to the set rotation angle and interval time, so that all the processing stations 23 are replaced in sequence.
[0123] Each clamping mechanism 231 is used to cooperate with the rotation of the rotating platform 21 to clamp and / or rotate the battery, so that when the battery located on the processing station 23 moves to the position of certain processing mechanisms 5, the clamping mechanism 231 horizontally clamps and rotates the battery to facilitate the processing mechanism 5 to process the battery.
[0124] The setting of the main control unit 4 enhances the coordination between the rotating device 22 and the clamping mechanism 231. For different processing stations 23, the clamping mechanism 231 performs different operations to achieve good processing effects. Through the rotation of the rotating device 22, different batches of batteries are driven to move synchronously to different processing mechanisms 5 in sequence with each processing station 23 according to the order of processing steps, so that the processing steps of the same batch of batteries are carried out, so that different batches of batteries are in different processing steps. Through the drive of the rotating device 22, they move synchronously to the next processing step, and the batteries do not need to be transmitted between multiple conveying mechanisms, which reduces the number of conveying mechanisms, simplifies the volume and structure of the system itself, and effectively improves production efficiency.
[0125] The shape of the rotating platform 21 includes a regular n-gon, and the loading conveyor line 1 and the unloading conveyor line 3 are arranged adjacent to each other, that is, the loading conveyor line 1 and the unloading conveyor line 3 are respectively connected to two different processing stations 23 on the rotating platform 21, and the two processing stations 23 are adjacent to each other, and the angle between the loading conveyor line 1 and the unloading conveyor line 3 is m degrees, wherein m×n=360;
[0126] Exemplarily, if the shape of the rotating platform 21 is a regular pentagon, the angle between the loading conveyor line 1 and the unloading conveyor line 3 is 72 degrees.
[0127] Specifically, in some embodiments of the present application, Figure 7 As shown, the clamping mechanism 231 includes a first clamping portion 61 and a second clamping portion 62;
[0128] The first clamping portion 61 is provided with a synchronization mechanism 64 and a rotation mechanism 63, the input end of the synchronization mechanism 64 is connected to the rotation mechanism 63, and the output end of the synchronization mechanism 64 is connected to at least two batteries, so as to realize synchronous rotation of all batteries;
[0129] It can be understood that the power of the rotating mechanism 63 can be transmitted to the synchronization mechanism 64, and then the multiple batteries are synchronously driven by the synchronization mechanism 64 to achieve synchronous movement of all batteries. It can be applied to steps such as laser roughening, plasma cleaning, three-dimensional spraying and pre-curing that require flipping the processing surface of the battery, and realizes the free rotation of the battery. It has better flexibility and helps to better complete the processing process.
[0130] Connecting the rotating mechanism 63 with multiple batteries from the same batch through the synchronization mechanism 64 helps to achieve synchronous movement of all batteries in the same processing batch. On the one hand, it can avoid to a certain extent the unbalanced or unstable clamping conditions caused by the difference in rotation speed between the batteries. On the other hand, the synchronous movement of multiple batteries helps to reduce difference factors and achieve consistency in processing effects and processing quality of each battery in the same batch.
[0131] An elastic member 65 is disposed on a side of the second clamping portion 62 facing the first clamping portion 61 for clamping the battery together with the first clamping portion 61 .
[0132] An elastic member 65 is provided on one side of the second clamping portion 62 facing the first clamping portion 61. The elastic member 65 can provide soft and uniform force when clamping the battery, and can also provide buffering force to reduce damage to the battery and mechanical structure and improve clamping stability and safety. The elastic member 65 can also adjust the clamping force so that the battery maintains a stable clamping state and can adapt to different battery sizes during rotation.
[0133] The first clamping portion 61 and the second clamping portion 62 are both provided with an adjustment assembly 66 at the bottom;
[0134] The adjusting assembly 66 is used to adjust the relative distance between the first clamping portion 61 and the second clamping portion 62 .
[0135] By adjusting the assembly 66, the distance between the first clamping portion 61 and the second clamping portion 62 can be adjusted, so that the clamping mechanism 231 can adapt to batteries of different sizes and shapes, and has strong adaptability and versatility;
[0136] On the other hand, the adjustment component 66 can also adjust the clamping force of the first clamping part 61 and the second clamping part 62 on the battery, which helps to improve the stability of the clamping process;
[0137] On the other hand, the battery can be moved and the relative position of the battery and the processing mechanism 5 can be changed by moving and cooperating the first clamping portion 61 and the second clamping portion 62 .
[0138] Specifically, in some embodiments of the present application, the adjustment component 66 includes a driving device 661, a slide rail 663 and a slider 662; when the detection mechanism 53 detects that there is a problem with the position of the battery, the battery position can be adjusted by the adjustment component 66 on the clamping mechanism 231.
[0139] Furthermore, if Figure 3 As shown, the three-dimensional spraying and pre-curing mechanism 54 in the processing mechanism 5 includes: a spraying device 541 and a pre-curing device 542;
[0140] The spraying device 541 and the pre-curing device 542 are arranged opposite to each other. One or both of the spraying device 541 and the pre-curing device 542 are provided with an adjustment structure 543 for adjusting the relative distance between the spraying device 541 and the pre-curing device 542 .
[0141] The integrated setting of the spraying device 541 and the pre-curing device 542 optimizes the connection time between the spraying and pre-curing steps. The spraying and pre-curing technologies are usually complementary. The insulation film coating after spraying needs to be pre-cured within an appropriate time to avoid the flow of the insulation film liquid, so as to achieve a uniform coating effect and good insulation performance, and realize close cooperation and optimization between technologies. The integrated spraying device 541 and the pre-curing device 542 enable seamless connection between the two steps, reducing quality problems caused by long waiting time or other delays.
[0142] The setting of the adjustment structure 543 can adjust the distance between the spraying device 541 and the pre-curing device 542, thereby affecting the spraying thickness of the insulating film, optimizing the spraying thickness, coating uniformity and pre-curing effect during the spraying process of the insulating film, so that the coating quality meets the expected requirements.
[0143] The setting of the adjustment structure 543 helps to allow the spraying device 541 to spray and the pre-curing device 542 to perform curing to meet the usage requirements of batteries of different specifications. During the spraying and pre-curing process, the final physical properties of the insulating film layer (such as hardness, adhesion, etc.) may be affected by the distance between the spraying and pre-curing devices 542. The distance between the spraying device 541 and the pre-curing device 542 can also be adjusted to thereby affect the interval time between the spraying step and the pre-curing step, thereby achieving different insulating film preparation effects.
[0144] Furthermore, if Figure 2 As shown, the feeding conveyor line 1 further includes a first feeding part 11, a feeding transfer mechanism 13 and a second feeding part 12;
[0145] The feeding direction of the first feeding part 11 forms an angle with the feeding direction of the second feeding part 12, and the angle of the angle is the same as the rotation angle set by the main control unit 4. The first feeding part 11 is provided with a code scanning mechanism 14, a removal mechanism 15 and a first conveying mechanism 71 for conveying the batteries on the first feeding part 11;
[0146] The second feeding part 12 is provided with a second conveying mechanism 72 and a third conveying mechanism 73;
[0147] The second conveying mechanism 72 is used to convey the batteries on the second loading part 12, and the third conveying mechanism 73 is used to convey the batteries located on the second loading part 12 to the rotary processing line 2;
[0148] Of course, the corresponding positions of the thickness measuring device 32 and the detection mechanism 53 may also be provided with the same or different removal mechanisms 15 .
[0149] The first loading part 11 and the second loading part 12 are arranged at an angle to cooperate with the operation of the rotary processing line 2. The first loading part 11 and the second loading part 12 help optimize the spatial layout of the battery insulating film preparation system, reduce the floor space, and improve space utilization.
[0150] Specifically, in some embodiments of the present application, the first conveying mechanism 71, the second conveying mechanism 72 and the third conveying mechanism 73 can all be realized by a fork structure. Of course, there is no limitation on the specific structures of the first conveying mechanism 71, the second conveying mechanism 72 and the third conveying mechanism 73.
[0151] The loading transfer mechanism 13 is located between the first loading part 11 and the second loading part 12. The loading transfer mechanism 13 transfers the battery from the first loading part 11 to the second loading part 12 by performing horizontal and vertical translation and rotation movements;
[0152] Wherein, no matter in the first loading part 11, the second loading part 12, the loading transfer mechanism 13, the clamping mechanism 231 or the removal mechanism 15, each battery is placed horizontally;
[0153] The preparation position of the insulating film on the outer surface of the circular battery is mainly concentrated on the curved surface. Horizontally clamping the battery helps to optimize the preparation effect and efficiency of the insulating film on the one hand, and on the other hand, it also helps to avoid contaminating the information code and protect the information code.
[0154] Placing batteries horizontally can reduce the risk of tilting and sliding during transportation and operation, thereby improving safety and stability. Horizontal placement helps reduce instability during transfer and clamping. Horizontal placement can also better protect the physical structure and internal components of the battery. Vertical placement of batteries may increase stress points and cause the risk of damage to the battery structure. Horizontal placement of batteries can make more efficient use of space. In the battery insulation film preparation system, it helps optimize the layout and workflow.
[0155] During the rotation time of each section of the rotary processing line 2, the loading transfer mechanism 13 is used to clamp the battery from the first loading part 11, complete the translation and horizontal rotation movement in the first direction, and place the battery on the second loading part 12. Within the preset time interval, the loading transfer mechanism 13 is used to move from the second loading part 12 to the first loading part 11, and complete the horizontal rotation movement in the second direction; the angle of the rotation movement is the same as the preset rotation angle, and the first direction is opposite to the second direction.
[0156] Through the mutual coordination between the loading operation of the loading conveyor line 1, the unloading operation of the unloading conveyor line 3 and the rotary processing line 2, the battery replacement time in the preparation process of the battery insulating film is effectively shortened, and the loading conveyor line 1, the rotary processing line 2 and the unloading conveyor line 3 are closely connected, which optimizes the preparation process of the insulating film and helps to improve the preparation effect of the insulating film.
[0157] Furthermore, if Figure 1 , Figure 2 and Figure 8 As shown, the plasma cleaning mechanism 52 in the processing mechanism 5 includes: a plasma nozzle 521, a first guide mechanism 522, and a second guide mechanism 523;
[0158] The plasma spray head 521 is respectively connected to the first guide mechanism 522 and the second guide mechanism 523, so that the plasma spray head 521 can move along the first guide mechanism 522 or the second guide mechanism 523;
[0159] The plasma nozzle 521 is respectively connected to the first guide mechanism 522 and the second guide mechanism 523 to facilitate the movement of the plasma nozzle 521. In cooperation with the rotational movement of the clamping mechanism 231, a better cleaning effect is achieved to clean away the debris generated by laser roughening to avoid the debris from adversely affecting the insulating film spraying effect, thereby improving the insulating film spraying effect.
[0160] Specifically, in some embodiments of the present application, the battery on the feeding conveyor line 1 is placed horizontally, and the side of the battery provided with the information code faces the laser texturing mechanism 51 in the processing mechanism 5, and the code scanning mechanism 14 is provided with a code scanning gun 511 on one side close to the laser texturing mechanism 51, and the code scanning gun 511 faces the feeding conveyor line 1, so as to facilitate the code scanning mechanism 14 provided on the feeding conveyor line 1 to scan the information code;
[0161] The plasma cleaning mechanism 52 and the laser texturing mechanism 51 are also provided with a collecting device 512 for absorbing dust.
[0162] The collecting device 512 can absorb dust and debris dropped after laser texturing or plasma cleaning to keep the environment clean.
[0163] The embodiments of the present application have at least the following beneficial effects:
[0164] The embodiment of the present application provides a battery insulating film preparation system, which adopts a 3D spraying process and is more efficient, faster, and suitable for large-scale automated production. It is suitable for the needs of large-scale automated production and improves production efficiency; optimizes the insulating film preparation effect, makes the insulating film more wear-resistant and pressure-resistant, and achieves a good adhesion effect;
[0165] Specifically, a rotating processing line 2 is provided to facilitate the transportation of batteries between different processing mechanisms 5. On the one hand, it optimizes the connection effect of different processing steps of the same batch of batteries, reduces the battery transportation time, and also helps to reduce the overall volume of the battery insulating film preparation system. On the other hand, different batches of batteries can be processed at the same time without interfering with each other, which helps to improve the efficiency of insulating film preparation; by unifying the restrictions on preparation time and preparation process, the consistency of insulating film preparation effect is improved.
[0166] Example 2
[0167] The embodiment of the present application provides a method for preparing a battery insulating film, which is applied to the battery insulating film preparation system of any one of the items in the first part;
[0168] like Fig.10 As shown, the method includes:
[0169] S100: The batteries of each batch are sequentially conveyed to the rotary processing line through the feeding conveyor line according to the time interval preset in the main control unit;
[0170] S200: rotating the main control unit at a preset rotation angle at a preset time interval by the rotary processing line, so as to sequentially perform processing steps including laser roughening, plasma cleaning, three-dimensional spraying and pre-curing on each batch of batteries conveyed to the rotary processing line, so that an insulating film is formed on the outer surface of the battery; wherein adjacent batches of batteries differ by one or more processing steps;
[0171] S300: The batteries of each batch are sequentially transferred out of the rotary processing line through the unloading conveyor line at a preset time interval;
[0172] S400: The battery transferred out of the rotary processing line is subjected to final curing treatment by a final curing mechanism to fix the spraying effect of the formed insulating film.
[0173] Specifically, in some embodiments of the present application, the main control unit sets the length of the time interval and the size of the rotation angle and the time of each rotation, and adjacent batches of batteries differ by one processing step.
[0174] It can be understood that, on the one hand, the insulating film on the outer surface of the battery is prepared by the battery insulating film preparation system, the effective connection between the various processing steps is realized by the rotating processing line, and the simultaneous transportation of multiple batches of batteries is realized by the same rotating device, so that the preparation of different batches of battery insulating films is carried out synchronously, which helps to improve the preparation efficiency and further improve the consistency of the battery processing effect; on the other hand, through the laser roughening, plasma cleaning, pre-curing and final curing preparation steps, the adhesion of the insulating film is enhanced, which can effectively avoid the problem of insulating film falling off.
[0175] Furthermore, before the feeding conveyor line sequentially conveys each batch of batteries to the rotary processing line at a preset time interval in the main control unit, the method further includes: based on the scanning and recognition results of each battery by the scanning mechanism, the main control unit controls the feeding conveyor line to convey the batteries that have successfully been scanned and recognized to the rotary processing line for processing, and the main control unit controls the removal mechanism to remove the batteries that have failed to be scanned and recognized from the feeding conveyor line;
[0176] It also includes: when the battery is removed from the battery insulation film preparation system, querying whether there is a record of information related to the battery insulation film preparation, and if there is a record related to the battery insulation film preparation, performing differentiated processing on the battery according to different battery information recording devices;
[0177] The battery information recording device includes one or more of a code scanning mechanism, a detection mechanism, and a thickness measuring device;
[0178] Among them, if the scanning mechanism successfully scans the battery, after the scanning mechanism sends the scanning and identification result to the main control unit, the main control unit automatically generates a record about the battery insulation preparation of the battery.
[0179] If there is no record related to the preparation of the battery insulating film, the information code of the battery is processed, and the processing of the information code of the battery includes: one or any multiple of information code repair, information code remaking, and information code cleaning.
[0180] It can be understood that by setting up the scanning mechanism, the detection mechanism, and the thickness measuring device, while serving as the basis for the implementation of the battery insulating film preparation steps, it is also possible to effectively monitor the entire process of battery insulating film preparation, and to find problems in the insulating film preparation according to the different positions of the batteries removed, to carry out targeted treatment of the batteries, and to improve the treatment efficiency and treatment effect.
[0181] For example, if a battery is removed from the production line after being scanned by a barcode scanning mechanism, it generally does not involve production quality issues, but there may be a problem with the information code. The most common problem is that the information code is contaminated. In this case, the information code will be repaired, remade or cleaned, and then continued to be put into the feeding conveyor line for preparation using the battery insulating film preparation system.
[0182] For example, if the product is removed from the production line after being inspected by the inspection agency, it is generally a production quality problem, and generally one or more of the laser texturing or plasma cleaning problems. It needs to be put back on the feeding conveyor line and prepared using the battery insulation film preparation system, focusing on completing the laser texturing or plasma cleaning.
[0183] Of course, the subsequent spraying and curing steps of the processing machine can also be performed only by an external laser texturing mechanism.
[0184] Of course, it is understandable that if the thickness measuring device is removed from the production line, there may be a problem in the three-dimensional spraying step, and it is necessary to re-spray, pre-cure and final cure treatment accordingly, so laser texturing is naturally not necessary.
[0185] By monitoring the entire process of insulating film preparation, the effective handling of defective products is improved, the processing speed is increased, the processing effect is optimized, which helps to reduce the defective rate, improve production efficiency and avoid waste of resources.
[0186] The rest of the contents are the same or similar to those in Example 1 and will not be repeated here.
[0187] Those skilled in the art will appreciate that the modules in the device in the implementation scenario can be distributed in the device in the implementation scenario according to the implementation scenario description, or can be changed accordingly and located in one or more devices different from the implementation scenario. The modules in the above implementation scenario can be combined into one module, or can be further split into multiple sub-modules.
[0188] The above serial numbers of the present invention are only for description and do not represent the advantages or disadvantages of the implementation scenarios.
[0189] The above disclosure is only a few specific implementation scenarios of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
