[Specific implementation method]

[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The backplane film roll cutting and punching equipment provided by the present application is mainly used to cut and punch the backplane film roll as a raw material to make multiple separate grid backplanes, and at the same time, the cutting and punching process of the backplane film roll is monitored and adjusted in real time to achieve accurate positioning of the cutting position and the punching holes on the backplane film roll. Punching and cutting are the core steps in the use of the entire equipment, so the backplane film roll needs to be transported to the exact position. The specific method of transportation can be selected according to needs, such as manual placement and automatic transportation. The preferred implementation method is cutting and punching under the automatic transportation method.

[0028] In the continuous manufacturing process, the backplane film roll is transported to the punching position by a conveying device. Specifically, the continuous film roll can be transported by a guide roller. After the punching is completed, it is transported to the cutting position for cutting to form the backplane of the required size. For the backplane film roll, since a grid pattern of a fixed size has been printed on the backplane film roll, although the total length of the cut backplane remains unchanged, the cumulative error will become larger and larger during slicing, and the grid pattern will shift, resulting in abnormalities in the punching hole position. Therefore, in order to avoid errors and ensure the yield of the product grid backplane, it is necessary to confirm whether the position of the backplane film roll is in the correct position during punching and cutting.

[0029] The automated, continuous backplane film processing process specifically includes the steps of unwinding, conveying, punching, cutting, and storing the backplane film mother roll. The components that pass through in sequence along the backplane film travel direction include: unwinding component 520, joint assembly 530, conveying device, punching assembly 200, positioning assembly 100, cutting assembly 300, and platform 400. Among them, the positioning assembly 100, the punching assembly 200, and the cutting assembly 300 are the core parts of this application.

[0030] In order to clearly explain the operation of the present application, some terms are now defined, including: the position for accurately punching the backplane mother roll is defined as the first preset position, the position for accurately cutting the backplane mother roll is defined as the second preset position, the direction in which the backplane roll film is conveyed along its own length direction is defined as the first preset direction, and the direction perpendicular to the conveying direction of the backplane roll film is defined as the second preset direction (i.e., the width direction of the backplane roll film itself).

[0031] Example 1

[0032] Please refer to Figure 1 , Figure 1 : is a schematic diagram of the structure of a backplane film cutting and punching device in an embodiment of the present application. First, the backplane film is punched and / or cut by the backplane film cutting and punching device. The backplane film can be moved along a first preset direction. The components of the device specifically include:

[0033] The positioning component 100 is used to collect and obtain the position information of the back plate film roll to determine the reference position of the back plate film roll and adjust the position of the back plate film roll;

[0034] The punching assembly 200 punches holes in the back plate roll film when the back plate roll film is at the first preset position;

[0035] The cutting assembly 300 cuts the backplane roll film when the backplane roll film is at the second preset position.

[0036] The back panel roll film is accurately positioned by the positioning component 100, and accurate punching and cutting of the punching component 200 and the cutting component 300 are achieved respectively. The punching component 200 and the cutting component 300 can work separately. In a preferred embodiment, the functions of punching and cutting are both utilized in a specific process, and the punching and cutting requirements are completed in one device. The cutting and punching equipment including the positioning component 100, the punching component 200 and the cutting component 300 can be used as an independent device alone, and can also be integrated into a continuous production line, for example, by cooperating with the unwinding component 520, etc., to realize continuous full-process automatic production.

[0037] The positioning component 100 is set to control the moving distance of the back panel film roll. The specific method is: by measuring and obtaining the reference position of each back panel film roll, combining the operating parameters of the conveying device, determining the time when the back panel film roll is in the first preset position and the second preset position, and obtaining the first preset position and the second preset position based on the reference position, that is, associating the start of the punching component 200 and the cutting component 300 with the reference position. In the above method, the measurement is performed each time, and the corresponding position is obtained according to the measurement result each time, which can effectively avoid the accumulation of errors generated in each process. In addition, the positioning component 100 can also adjust the position at the same time during measurement, for example, using a camera automatic deviation corrector, which can adjust the position when an abnormality is found in the position detection. In the scheme of the present application, the horizontal and vertical positions are accurately judged by combining the reference position with the equipment components, and each back panel film roll is positioned to achieve precise cutting and punching. The specific settings and operation methods of the camera automatic deviation corrector are as follows: configure a camera, a displacement device and a controller. The displacement device is used to move the conveying roller in the second preset direction. The camera captures the position of the back plate film in the second preset direction and transmits the relevant position information to the controller. The controller adjusts the conveying roller in the second preset direction through the displacement device according to the position information. The adjusted conveying roller can be one or more, thereby adjusting the position of the back plate film in the second preset direction.

[0038] Example 2

[0039] See also Figure 2 , Figure 2 : is a schematic diagram of the structure of a backplane film cutting and punching device in another embodiment of the present application, wherein the positioning component 100 is further refined, and the positioning component 100 includes:

[0040] The sensing positioning component 110 is used to obtain the position information of the back plate film roll to determine the reference position of the back plate film roll;

[0041] The automatic deviation-correcting component 120 is used to adjust the position of the back plate film roll along a second preset direction perpendicular to the first preset direction.

[0042] The specific method of confirming whether it is in the preset position by the sensing positioning component 110 includes determining the reference position of the back panel film according to a specific feature on the back panel film, and determining when the back panel film is located at the first preset position and when it is located at the second preset position in combination with the operating parameters of the length traction component in the equipment. For example, when obtaining the reference position, the length traction component starts to calculate the conveying length, and after determining the conveying set length according to the relevant dimensions of the back panel film, it is determined that the back panel film has reached the punching position, and the back panel film can also be determined to have reached the cutting position in the same way. Specifically, the initial position of the sensing positioning component 110 is located in the blank area of ​​the back panel film. When the sensing positioning component 110 detects that the back panel film has moved to the reference position, the first preset position and the second preset position are determined according to the reference position and the operating parameters, and the corresponding punching component 200 or cutting component 300 is respectively started after reaching the preset position.

[0043] In this embodiment, the sensing positioning component 110 can adopt a light sensing positioning method, and the automatic deviation correction component 120 adopts a camera automatic deviation corrector. Image processing and computer vision technology are used to capture the image of the target object, and the image processing algorithm is used to extract the features of the target object, such as edges, corners, etc., and then the reference position information of the backplane film roll is determined based on the position information of these features in the image and the parameters of the relevant devices. Combined with the continuous feeding method of the film roll, the light sensing positioning component 110 can identify the grid pattern in the backplane film roll and achieve precise positioning in the first preset direction; in the camera automatic deviation corrector, the camera can capture "one side" of the grid pattern. When the cutting and punching equipment is working, the backplane film roll can be driven straight forward to achieve precise alignment in the second preset direction.

[0044] Please continue reading Figure 2 The present application further provides a matching component to further expand the backplane film cutting and punching device, and the backplane film cutting and punching device can further include a platform 400, which is arranged at the next station of the cutting component 300, and is used to collect the cut and / or punched grid backplane. After the cutting and punching is completed, the backplanes are stacked and placed one by one through the backplane placement platform 400.

[0045] Similarly, the present application further provides a matching component to further expand the backplane film cutting and punching device, and the backplane film cutting and punching device can further include a reeling component 520 for storing and receiving the backplane film to be cut and a joint assembly 530 for switching the backplane film. The reeling component 520 can be set as a reel, and the backplane film mother roll to be cut and punched is wound onto the reel for transmission; the joint assembly 530 is used to switch the rolls during continuous production, and is used to connect the front and rear rolls of the backplane film together.

[0046] On the basis of achieving precise positioning for punching and cutting, in order to further improve the automation level of the equipment, the back panel film cutting and punching equipment can be further provided with a conveying device, which includes a length traction component 510, a rewinding traction component 540 and a floating swing arm component 550. The length traction component 510 controls the traction of the back panel film in the length direction and measures the conveying length of the back panel film. The rewinding traction component 540 is used to pull the back panel film out of the parent roll. The floating swing arm component 550 is used to tension and store the roll along a first preset direction.

[0047] Specifically, the unwinding traction assembly 540 can be configured as two fixed rollers driven by a motor or other driving device, the rotation axis direction of the fixed rollers is perpendicular to the transmission direction of the back plate film roll, and the two fixed rollers are respectively located above and below the back plate film roll, and are tightly fitted to the upper and lower surfaces of the back plate film roll. Driven by the unwinding traction assembly 540, the back plate film roll is transported to the next process;

[0048] The floating swing arm assembly 550 can be configured as a plurality of floating rollers, and each floating roller is installed at a different level. The back plate film to be processed passes through each floating roller in turn and is always kept in a tensioned state. The rotation axis direction of each floating roller is perpendicular to the transmission direction of the back plate film. At the same time, when the back plate film to be processed is in the floating swing arm assembly 550, the curved conveying path can also play a role in storing materials for the back plate film.

[0049] The length traction assembly 510 is also configured as two fixed rollers driven by a motor. The rotation axis direction of the fixed rollers is perpendicular to the transmission direction of the back panel film roll, and the two fixed rollers are respectively located above and below the back panel film roll, and are tightly fitted with the grid back panel. Driven by the length traction assembly 510, the back panel film roll is transported to the next process; at the same time, the length traction assembly 510 also includes a measuring part for counting the number of rotations of the fixed rollers, thereby indirectly obtaining the transmission distance of the back panel film roll. Before processing, the parameter information of the back panel film roll to be processed is preset to facilitate the punching or cutting process after the back panel film roll is transported to a fixed length;

[0050] Specifically, after the length traction component 510 locates the reference position through the light sensing positioning component 110, it can count the operating parameters of the length traction component 510, and calculate the conveying length of the back panel roll film according to the operating parameters, thereby obtaining the first preset position and the second preset position information of the back panel roll film. For example, one conveying length is a parameter for the distance the back panel roll film is conveyed before punching, and the other conveying length is a parameter for the distance the back panel roll film is conveyed before the cutting blade starts slicing.

[0051] In a complete scheme for cutting and punching in an automated manner, the backplane film roll passes through the unwinding component 520, the joint assembly 530, the unwinding traction component 540, the floating swing arm component 550, the punching assembly 200, the automatic deviation correction component 120, the length traction component 510, the induction positioning component 110, the cutting assembly 300 and the platform 400 in sequence through the roller. The unwinding traction component 540 and the length traction component 510 are set in the form of active rollers, and the other rollers can be set in the form of driven rollers. The above-mentioned components form a roll-to-roll method to transmit continuous backplane film rolls. During the whole process, except for the operation of unwinding and jointing, all can be realized automatically, which improves the degree of automation and can reduce operating costs. At the same time, it should be understood that in this embodiment, the arrangement order between the components that the backplane film roll passes through in sequence is not fixed. The arrangement order between the components can be changed and improved without affecting the cutting and punching processing of the backplane film roll and maintaining the height positioning.

[0052] In the above technical solution, the continuous roll film supply is firstly carried out by means of conveyor rollers to realize automatic and continuous processing. The reference position is obtained by the positioning component 100, and each grid back plate is positioned, punched and cut separately in combination with the operating parameters of the active traction component, without the influence of cumulative error. In the above method, the roll film can be transported all the time, and the punching component 200 and the cutting component 300 can use a fast punching and cutting method, and by coordinating with a suitable conveying rate, punching and cutting can be realized during transportation, so as to realize fast and automatic processing.

[0053] In order to avoid damage to the mesh back plate during the automatic cutting and punching process, based on the above content, the present application further improves the cutting assembly 300, and the cutting assembly 300 includes a blowing component, and the air outlet of the blowing component faces the back of the mesh back plate. By blowing air to the back of the mesh back plate, the gas forms an air cushion effect on the back of the mesh back plate, avoiding direct contact between the upper and lower back plates during movement, reducing friction between the sheets, and avoiding abnormalities such as scratches on the back plate.

[0054] In a specific embodiment of the cutting assembly 300, the cutting assembly 300 includes an upper cutting knife and a lower cutting knife, and the blowing component is installed on the knife holder of the lower cutting knife to ensure that the grid backboard can be placed flat on the placement platform after cutting without causing abnormal wrinkles. In addition, the friction between the sheets can be reduced to avoid abnormal scratches on the backboard. The specific method of the cutting assembly 300 can be selected as a cutting knife, the lower knife holder is fixed, and the upper blade is selected as a blade with a certain slope. The working principle of the cutting knife is similar to scissors or a paper cutter to achieve rapid cutting of the backboard roll film.

[0055] The backplane film cutting and punching device of the present application is further described below through a specific implementation method combined with relevant principles. Figure 3 , Figure 3 This is a schematic diagram of the principle of the backplane film cutting and punching device in one embodiment of the present application during use. Figure 3 For a top-down perspective, the continuous backplane roll film includes a grid pattern 610, a blank area 620, and a punching position 630, and is transported in a continuous conveying manner along a first preset direction (the direction of the arrow in the figure). The grid pattern 610 is formed by coating reflective material, and its size and position correspond to the gap size and position between the battery cells in the assembly. The blank area 620 is the portion of the grid pattern that is not coated with reflective material. The size and position of each blank area 620 correspond to the size and position of the corresponding battery cell in the assembly. A grid pattern 610 includes multiple blank areas 620 and at least one punching position 630. In the continuous roll film, a blank area 640 is set between two adjacent grid backplanes to be cut. The cutting and punching equipment includes light sensing positioning, a camera automatic deflection corrector, a cutting blade, and a punching device. The camera automatic deflection corrector captures the running trajectory of "one side" of the grid pattern, for example Figure 3 The dotted line position in .

[0056] The specific usage of cutting and punching equipment is as follows:

[0057] First, the back panel film roll to be processed is cut into specified widths, and a certain width of blank area 640 will be left on both sides of the grid pattern on the back panel film roll; then the back panel film roll is installed on the reel of the unwinding component 520, and passes through the joint component 530, the unwinding traction component 540, the floating swing arm component 550, the punching component 200, the automatic correction component 120, the length traction component 510, the induction positioning component 110, the cutting component 300 and the platform 400 in sequence.

[0058] When the backplane film passes through the automatic correction component 120, the camera of the automatic correction component 120 can capture "one side" of the grid pattern and perform automatic correction calibration; when the backplane film passes through the inductive positioning component 110, the initial position of the inductive positioning component 110 is set, preferably in the blank area 620, for example, Figure 3 The blank area 620 at the upper left corner of the middle grid pattern 610. After completing the relevant initial settings, the equipment performs automatic operation, and the backplane roll film is conveyed along the first preset direction;

[0059] When the back panel roll film passes through the cutting component 300, the staff manually adjusts the blank area 640 between two adjacent parts to be cut to form the grid back panel to be directly below the upper cutting knife of the cutting component 300, and adjusts it to the length of the blank area 640 on both sides of the adjacent grid back panels after cutting by the cutting component 300. Finally, it is transferred to the platform 400 via rollers for finished product storage.

[0060] During the transmission of the backplane film roll, the photoelectric sensing positioning component 110 locates the pattern of the first grid and then starts to record the moving distance. The cutting and punching equipment needs to set two length parameters in advance, one is the parameter for the distance of the backplane film roll before the punching is implemented, and the other is the parameter for the number of meters of the backplane film roll that the cutting blade starts slicing. When the number of meters of the backplane film roll transmitted along the first preset direction reaches the punching length parameter, the punching device starts to complete the punching; then the backplane film roll continues to be transmitted along the first and color number directions. The number of meters reaches the cutting length parameter, and the cutting blade starts. After the cutting is completed, a complete grid backplane is obtained.

[0061] After completing the punching and cutting, a completion signal is sent to the photoelectric sensing positioning component 110, and the photoelectric sensing positioning component 110 can be reset to wait for the pattern of the first grid in another grid backplane to arrive as the starting point of a new operation cycle, and perform the reciprocating cycle steps to complete the punching and cutting actions.

[0062] During the entire cutting process, the blowing component of the cutting assembly 300 continues to work and blows air to the back of the back plate roll film to ensure that when the back plate roll film is cut, it will not immediately contact the placement platform, thereby achieving flat placement without causing abnormal wrinkles; in addition, the blown gas forms a buffer pad-like effect, which can reduce the friction between the sheets and avoid abnormal scratches on the back plate. The cutting and punching device of the present application can continuously and stably perform cutting and punching without the phenomenon of grid pattern deviation and incorrect punching.

[0063] As can be seen from the foregoing, the present application ensures that the backplane film roll is accurately positioned in both the horizontal and vertical directions through a carefully designed positioning component 100, thereby achieving the high-precision requirements for cutting and punching. In addition, through seamless cooperation with the roll-to-roll conveyor device, the unwinding traction component 540, the length traction component 510 and the floating swing arm component 550 of the conveyor device are utilized to ensure the continuous and stable supply and caching of the film roll, meeting the needs of automated continuous cutting and punching of the backplane film roll. It is worth mentioning that the cutting component 300 is specially equipped with a blowing component. This innovative design not only ensures that the backplane film roll can be placed flat on the platform during the cutting process to avoid the occurrence of abnormal situations such as wrinkles, but also reduces the friction between the sheets, effectively preventing the occurrence of quality problems such as scratches on the backplane. This series of professional designs ensures the efficiency and quality of the grid backplane manufacturing process.

[0064] The above is only a specific implementation of the present application, and any improvements made based on the concept of the present application are deemed to be within the protection scope of the present application.
