Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to a release film separation device, a film pasting system and a pre-separation device. BACKGROUND

[0002] In the production process of a battery, a protective film is usually pasted on the outer surface of the battery for the purpose of protecting the battery, preventing damage, or beautifying the appearance of the battery. In the film pasting process, the film body of the protective film needs to be separated from the release film, and then the film body is pasted on the outer surface of the battery. However, the success rate of film tearing of the existing release film is low, and the waste of the protective film is serious. SUMMARY

[0003] The release film separation device, the film pasting system and the pre-separation device provided by the present application aim to solve the problem of low film tearing success rate of the existing release film and easy waste of the protective film.

[0004] To solve the above technical problems, one technical solution adopted by the present application is to provide a release film separation device. The release film separation device comprises:

[0005] The pre-separation device comprises:

[0006] The bearing mechanism comprises a bearing platform configured to bear the protective film; the protective film comprises a laminated film body and a release film;

[0007] The separation mechanism comprises a separation piece configured to extend between the film body and the release film from a side where the pre-separation edge of the protective film is located, so as to separate the pre-separation edge of the film body and the release film;

[0008] The film tearing device is configured to completely separate the release film from the film body after the pre-separation edge of the film body and the release film is separated; the film tearing device comprises a film tearing mechanism and a first robot; the first robot is configured to grab the film body from the bearing platform and move the protective film to the film tearing mechanism; the film tearing mechanism is configured to grab the release film of the protective film grabbed by the first robot and move relative to the first robot, so as to completely separate the release film from the film body.

[0009] The above-mentioned release film separation device realizes the pre-separation between the pre-separation edges of the film body and the release film by setting a pre-separation device and making the pre-separation device include a separation mechanism, the separation mechanism includes a separation piece, and the separation piece can be inserted between the film body and the release film from the side where the pre-separation edge of the protective film is located to separate the pre-separation edges of the film body and the release film. Then, the pre-separated release film is completely separated from the film body by the film tearing device. The pre-separation method effectively reduces the risk that the pre-separation edges of the film body and the release film cannot be torn from the film body or cause the release film to tear due to increased adhesion, improves the success rate of tearing the release film, and reduces the waste of protective films. In addition, the first robot can move the protective film on the bearing platform to facilitate the pre-separation of the next protective film by the pre-separation device, thereby improving production efficiency. The first robot can cooperate with the film tearing mechanism to completely separate the pre-separated film body and the release film, thereby completing the entire film tearing process of the protective film.

[0010] In one embodiment, the separation piece includes an insertion part configured to be inserted between the film body and the release film.

[0011] The above-mentioned scheme sets the anti-adhesion structure on the surface of at least the insertion part of the separation piece. During the insertion of the insertion part into the protective film, the anti-adhesion structure can be in anti-adhesion contact with the release film and the protective film, respectively, thereby reducing the risk that the adhesion layer is adhered to the insertion part, making it difficult for the insertion part to be inserted into or out of the protective film, and making the insertion part smoothly inserted into or out of the protective film. In addition, it can reduce the adhesion layer left on the insertion part and reduce the manual maintenance of the insertion part.

[0012] In one embodiment, the separation mechanism is slidingly connected to the bearing mechanism in a direction intersecting the bearing surface of the bearing platform. In this way, the height of the separation piece relative to the bearing surface of the bearing platform can be adjusted to enable the separation piece to be more accurately inserted between the release film and the film body.

[0013] In one embodiment, the bearing mechanism further includes a support column, and the bearing platform is arranged on the support column.

[0014] The separation mechanism further includes a first driving piece connected to the separation piece and configured to drive the separation piece to move in a direction parallel to the surface of the bearing platform to be inserted between the film body and the release film or to be inserted out of the film body and the release film.

[0015] The first driving piece is slidingly connected to the support column in the axial direction of the support column.

[0016] The above scheme has the advantages that the first driving member drives the separating member to move, the automation degree is high, the length of the separating member extending into the protective film can be more accurately controlled, and the risk of wrinkles on the film body or the film body being lifted by the separating member is reduced. In addition, the first driving member is slidingly connected to the support column to achieve sliding connection of the separating mechanism and the bearing mechanism, which is simple in structure and convenient to operate.

[0017] In one embodiment, the pre-separating device further comprises a fixing mechanism connected to the bearing mechanism and configured to fix the side of the pre-separation edge of the release film on the bearing platform. In this way, during the pre-separation of the film body and the release film, the risk of movement of the release film relative to the bearing platform is reduced, and the risk of the release film being lifted by the separating member is reduced, thereby improving the pre-separation effect.

[0018] In one embodiment, the fixing mechanism comprises:

[0019] The second driving member is connected to the bearing mechanism;

[0020] The pressing block is connected to the second driving member, and the second driving member is configured to drive the pressing block to move along the height direction of the bearing mechanism towards the direction of approaching or moving away from the bearing platform to compress or loosen the release film.

[0021] The above scheme can directly compress the release film on the bearing platform by the pressing block, which is convenient and fast, and the damage to the release film and the bearing platform is smaller than that of the fixing method in which the clamping or fixing member sequentially passes through the release film and the bearing platform.

[0022] In one embodiment, the pressing block is an elastic block, or the side surface of the pressing block facing the bearing platform is provided with an elastic pad. In this way, the friction between the pressing block and the release film can be increased, thereby reducing the risk of relative displacement between the pressing block and the release film. At the same time, the pressing block contacts the surface of the release film through the elastic structure, and since the material of the elastic structure is soft, the risk of damage to the release film is reduced, and the risk of rupture of the release film during the pre-separation process is reduced.

[0023] In one embodiment, the pre-separating device further comprises a sensor disposed on the bearing platform and electrically connected to the second driving member, the sensor is configured to sense the protective film and send a pressing signal in response to sensing the protective film, and the second driving member drives the pressing block to move towards the bearing platform in response to the pressing signal.

[0024] The above scheme can automatically sense whether the protective film is placed on the bearing platform by the sensor, and automatically control the pressing block to move downward to compress and fix the release film when the protective film is placed on the bearing platform. The automation degree of this scheme is high, and the separation efficiency of the release film can be effectively improved.

[0025] In one embodiment, the second driving member is configured to drive the pressing block to move away from the bearing platform in response to the number of times the separating member extends into the space between the film body and the release film reaching a preset number. In this way, the pressing block can be automatically controlled to move away from the bearing platform to release the release film, and the separation efficiency of the release film can be further improved.

[0026] In one embodiment, the number of the fixing mechanisms is two, and the two fixing mechanisms are located on the same side of the bearing platform along the first direction of the bearing platform; the two fixing mechanisms are configured to fix the two ends of the side of the release film where the pre-separation edge is located on the bearing platform. In this way, the relative position stability of the release film on the bearing platform can be improved, and the risk of movement of the release film relative to the bearing platform during the pre-separation process can be reduced, thereby effectively improving the pre-separation effect.

[0027] In one embodiment, the two fixing mechanisms are located on the two sides of the separating member along the second direction; and the second direction is perpendicular to the first direction. In this way, the interference of the two fixing mechanisms with the movement of the separating member along the first direction can be reduced.

[0028] In one embodiment, the bearing platform is provided with a suction accessory, and the suction accessory is configured to suction the protective film from the side surface of the protective film towards the bearing platform.

[0029] The above scheme can fix the protective film on the bearing platform by the suction accessory, and the risk of movement or falling of the protective film from the bearing platform can be reduced. Meanwhile, the suction accessory and the pressing block can fix the protective film from the upper and lower surfaces of the protective film, respectively, and the risk of movement of the protective film relative to the bearing platform can be further reduced, thereby effectively improving the pre-separation effect of the film body and the release film.

[0030] To solve the above technical problems, another technical solution adopted by the present application is to provide a film pasting system, which comprises the above-mentioned release film separating device.

[0031] To solve the above technical problems, still another technical solution adopted by the present application is to provide a pre-separation device, which comprises:

[0032] The bearing mechanism comprises a bearing platform, and the bearing platform is configured to bear the protective film; the protective film comprises a film body and a release film stacked together;

[0033] The separating mechanism comprises a separating member, and the separating member is configured to extend into the space between the film body and the release film from the side where the pre-separation edge of the protective film is located, so as to separate the pre-separation edge of the film body and the release film.

[0034] The above scheme realizes the pre-separation between the pre-separation edge of the film body and the release film by making the pre-separation device include a separation mechanism, the separation mechanism includes a separation piece, and the separation piece can extend into the film body and the release film from the side where the pre-separation edge of the protective film is located to separate the pre-separation edge of the film body and the release film. The scheme effectively reduces the risk that the pre-separation edge of the film body and the release film cannot be torn from the film body or causes the release film to be torn due to increased adhesion, improves the success rate of tearing the release film, and reduces the waste of the protective film.

[0035] In one embodiment, the separation piece includes an extending portion configured to extend into the film body and the release film; and wherein at least a surface of the extending portion of the separation piece is provided with an anti-adhesion structure.

[0036] The above scheme reduces the glue left on the extending portion by providing the anti-adhesion structure on at least the surface of the extending portion of the separation piece, and reduces the manual maintenance of the extending portion when the extending portion extends into the film body and the release film.

[0037] In one embodiment, the separation mechanism is slidingly connected to the bearing mechanism in a direction intersecting the bearing surface of the bearing platform. In this way, the height of the separation piece relative to the bearing surface of the bearing platform can be adjusted to enable the separation piece to extend more accurately into the release film and the film body.

[0038] In one embodiment, the pre-separation device further includes a fixing mechanism connected to the bearing mechanism and configured to fix the side where the pre-separation edge of the release film is located to the bearing platform. In this way, during the pre-separation of the film body and the release film, the risk of movement of the release film relative to the bearing platform can be reduced, thereby improving the pre-separation effect.

In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0053] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments in accordance with the application.

[0054] In the description of the embodiments of the application, the term“and / or” only means an association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character“ / ” herein generally means that the front and rear associated objects have an“or” relationship.

[0056] In the description of the embodiments of the application, the technical terms“center”,“longitudinal”,“transverse”,“length”,“width”,“thickness”,“upper”,“lower”,“front”,“rear”,“left”,“right”,“vertical”,“horizontal”,“top”,“bottom”,“inner”,“outer”,“clockwise”,“counterclockwise”,“axial”,“radial”,“circumferential” and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the application.

[0057] In the description of the embodiments of the application, unless otherwise explicitly specified and limited, the technical terms“mounting”,“connection”,“connection”,“fixing” and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship of two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the embodiments of the application can be understood according to the specific circumstances.

[0058] The protective film possesses good adhesion, thermal conductivity, flame retardancy, and high-temperature resistance, reducing the risk of adhesion failure and detachment due to high temperatures. Furthermore, the protective film can withstand high temperatures, preventing the spread of fire if the battery catches fire. Therefore, to ensure the production quality of battery modules and improve their insulation and stability, a protective film is typically applied to the surface of the battery module. This quickly dissipates the heat generated during charging and discharging, helping the battery maintain a suitable operating temperature range and reducing the risk of performance degradation or safety hazards due to overheating.

[0059] In related technologies, protective films are typically applied to the outer surface of batteries manually. Specifically, the protective film is removed from the hopper, the release liner is peeled off, and then the protective film is applied to the battery's outer surface in the correct orientation after the release liner has been completely removed. However, manual application is inefficient and has low precision, resulting in high rework rates and poor consistency.

[0060] Moreover, as Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a protective film provided in one embodiment of this application. When the protective film 200 is received, it typically has one side where the edge of its release film 202 extends beyond the edge of the film body 201. The portion of the release film 202 extending beyond the film body 201 is referred to as the "excess portion." The edges of the release film 202 at other locations, distinct from the excess portion, coincide with the edge of the film body 201. Furthermore, the protective film 200 has a relatively thick adhesive backing. During the incoming material cutting process, adhesive residue may remain at the edges of the protective film 200. After a period of settling, the adhesive at the edges of the protective film 200 undergoes an oxidation reaction or moisture evaporation, increasing its adhesion and causing it to adhere to the release film 202. In this way, when peeling off the release film 202, the release film 202 and the film body 201 are at the initial peeling position, and the release film 202 cannot be peeled off or the release film 202 is torn. This results in a low success rate of peeling off the release film 202, which is only about 35%. This leads to a serious waste of the protective film 200 and requires frequent shutdowns.

[0061] Based on this, this application provides a new release film separation device, which can not only replace manual operation and realize automated film application, thereby improving film application efficiency and accuracy, reducing rework rate, and improving film application consistency, but also pre-separates the pre-separation edge E of the protective film through a pre-separation device, and then completely separates the release film 202 and the film body 201 through a film tearing device. This effectively reduces the risk that the release film 202 cannot be torn off the film body 201 due to increased adhesion at the pre-separation edge E of the film body 201 and the release film 202, or causes the release film 202 to tear. This improves the success rate of tearing the release film 202 and reduces the waste of the protective film 200.

[0062] The application will be described in detail below with reference to the accompanying drawings and examples.

[0063] Please refer to Figures 2 to 5 , Figure 2 The overall structure schematic diagram of the protective film 200 provided by an embodiment of the application is placed on the pre-separation device 100. Figure 3 For Figure 2 The top view of the structure shown. Figure 4 The front view of the structure shown. Figure 2 The front view of the structure shown. Figure 5 The side view of the structure shown. Figure 2 The side view of the structure shown.

[0064] In one embodiment, a release film separation device is provided. The release film separation device comprises a pre-separation device 100 and a film tearing device (not shown in the figure). The pre-separation device 100 comprises a bearing mechanism 10 and a separation mechanism 20; the bearing mechanism 10 comprises a bearing platform 11 configured to bear a protective film 200; the protective film 200 comprises a laminated film body 201 and a release film 202. The separation mechanism 20 comprises a separation piece 21 configured to protrude between the film body 201 and the release film 202 from the side where the pre-separation edge E of the protective film 200 is located, so as to separate the pre-separation edge E of the film body 201 and the release film 202. The film tearing device is configured to completely separate the release film 202 from the film body 201 after the pre-separation edge E of the film body 201 and the release film 202 is separated. The film tearing device comprises a film tearing mechanism and a first robot. The first robot is configured to grab the film body 201 from the bearing platform 11 and move the protective film 200 to the film tearing mechanism; the film tearing mechanism is configured to grab the release film 202 of the protective film 200 grabbed by the first robot and move relative to the first robot, so as to completely separate the release film 202 from the film body 201.

[0065] The protective film 200 is configured to be attached to the outer surface of the product to be attached. In one example, the protective film 200 is configured to be attached to the outer surface of a battery; the following embodiments of the application are all taken as examples. Among them, the battery can be a battery monomer, and the battery monomer can be a lithium ion secondary battery, a lithium ion primary battery, a lithium-sulfur battery, a sodium lithium ion battery, a sodium ion battery or a magnesium ion battery, etc.; the battery monomer can be in the shape of a cylinder, a flat body, a cuboid or other shapes, etc.; the battery monomer can adopt different packaging methods to form a cylindrical battery monomer, a square battery monomer or a soft package battery monomer, etc. Alternatively, the battery can also be a modular structure including one or more battery monomers to provide higher voltage and capacity, such as a battery assembly, a battery pack, etc.

[0066] The protective film 200 is a film with adhesive on one side, so that the protective film 200 can be attached to the battery via the adhesive. The protective film 200 can be a protective film 200 of various materials, for example, a protective film 200 made of an insulating material, a protective film 200 made of other non-insulating materials, and the like. For example, the protective film 200 can be mica paper.

[0067] In one example, the protective film 200 includes a release film 202, an adhesive layer, and a film body 201 stacked in sequence. The adhesive layer can be an optical adhesive layer, for example, an OCA (Optically Clear Adhesive) adhesive. Alternatively, the adhesive layer can also be a non-optical adhesive layer. The film body 201 is configured to be attached to the outer surface of the battery. The release film 202 is configured to protect the adhesive layer, so as to reduce the risk of the adhesive layer being contaminated and affecting the adhesion of the adhesive layer.

[0068] In one example, in order to facilitate separation of the release film 202, the pre-separation device 100 separates the release film 202 from the side edge of the film body 201. In this example, the pre-separation edge E of the protective film 200 is the side edge of the protective film 200 where the edge of the release film 202 exceeds the edge of the film body 201. The pre-separation edge E of the protective film 200 refers to the edge corresponding to the stacked part of the film body 201 and the release film 202, and does not include the excess part of the release film 202.

[0069] The length of the pre-separation edge E of the protective film 200 along the first direction X can be set according to actual conditions, as long as the release film 202 can be successfully separated from the film body 201 after the pre-separation edge E of the protective film 200 is pre-separated.

[0070] As an example, the ratio of the length of the pre-separation edge E of the protective film 200 along the first direction X to the length of the film body 201 along the first direction X can be less than or equal to 0.2. For example, the length of the pre-separation edge E of the protective film 200 along the first direction X can be greater than or equal to 5 mm and less than or equal to 15 mm. That is, the length of the separation piece 21 extending into the release film 202 and the film body 201 along the first direction X is greater than or equal to 5 mm and less than or equal to 15 mm. For example, the length of the pre-separation edge E of the protective film 200 along the first direction X can be 5 mm, 8 mm, 10 mm, 12 mm, or 15 mm.

[0071] In combination Figure 2 When the protective film 200 is placed on the carrying platform 11, the pre-separation edge E of the protective film 200 along the first direction X is located at one end of the carrying platform 11. The protective film 200 can be placed on the carrying platform 11 by the second robot.

[0072] The carrying platform 11 has a carrying surface which is horizontal and has an area larger than that of the protective film 200 so as to ensure that the protective film 200 can be completely attached to and disposed on the carrying surface. The carrying platform 11 can be a substrate or a base. As an example, the carrying platform 11 has a rectangular cross section, and the first direction X can be the length direction of the carrying platform 11.

[0073] The separating member 21 can move back and forth along the first direction X to extend into or out of the space between the film body 201 and the release film 202. In an example, the separating member 21 has opposite first and second ends along the first direction X, and the first end of the separating member 21 is configured to be extended into the space between the film body 201 and the release film 202 first. The thickness of the first end of the separating member 21 gradually decreases in the direction from the second end towards the first end, so as to facilitate the separating member 21 to smoothly extend into and out of the protective film 200. The thickness of the separating member 21 refers to the dimension of the separating member 21 along the height direction Z of the carrying mechanism 10.

[0074] As an example, the side surface of the separating member 21 facing the carrying platform 11 is parallel to the carrying surface of the carrying platform 11. In this way, the separating member 21 can be attached to the surface of the release film 202 at all times during the process of extending into or out of the protective film 200, so as to reduce the risk of damaging the film body 201 and the release film 202 by the first end of the separating member 21 and the risk of lifting or wrinkling the film body 201 and the release film 202 by the separating member 21.

[0075] The thickness of the separating member 21, especially the part of the separating member 21 used to extend into the protective film 200, is relatively thin, so as to facilitate the extension into the protective film 200 and reduce the impact on the film body 201. In an example, the thickness of the separating member 21 can be greater than or equal to 0.3 mm and less than or equal to 0.5 mm. As an example, the thickness of the separating member 21 can be 0.3 mm, 0.4 mm or 0.5 mm, etc.

[0076] The film tearing device specifically grabs the protective film 200 on the carrying platform 11 after the pre-separation process, and then separates the film body 201 from the release film 202. As an example, the film tearing device can grab the protective film 200 through the film body 201.

[0077] In an example, the first robot and the second robot can be two different robots. In this way, the second robot can simultaneously transfer and place another protective film 200 on the carrying platform 11 to perform the pre-separation of the other protective film 200 during the process of moving the protective film 200 to the film tearing mechanism by the first robot, so as to improve the work efficiency.

[0078] Of course, in other examples, the first robot and the second robot can also be the same first robot.

[0079] The film tearing mechanism can move relative to the first robot, can be that the first robot does not move, the film tearing mechanism moves; or the film tearing mechanism does not move, the first robot moves; or the film tearing mechanism and the first robot both move, as long as it can tear off the release film 202.

[0080] In some examples, the first robot adsorbs the film body 201 of the protective film 200 after the pre-separation treatment from the carrying platform 11, and moves the entire protective film 200 to the position where the film tearing mechanism is located. The film tearing mechanism grabs the part (i.e. the excess part) of the release film 202 that exceeds the film body 201, and moves relative to the first robot until the film body 201 and the release film 202 are completely separated.

[0081] For example, the film tearing mechanism includes a third driving member and a clamping jaw, and the clamping jaw is configured to clamp the part of the release film 202 that exceeds the film body 201. The third driving member is connected with the clamping jaw and is configured to drive the clamping jaw to move relative to the first robot to separate the release film 202 from the film body 201.

[0082] The release film separation device provided by the embodiment separates the pre-separation edge E of the film body 201 and the release film 202 by setting the pre-separation device 100 and making the pre-separation device 100 include the separation mechanism 20, the separation mechanism 20 includes the separation member 21, and the separation member 21 can extend into the film body 201 and the release film 202 from the side where the pre-separation edge E of the protective film 200 is located, so as to separate the pre-separation edge E of the film body 201 and the release film 202, thereby realizing the pre-separation between the pre-separation edge E of the film body 201 and the release film 202; and then the pre-separated release film 202 and the film body 201 are completely separated by the film tearing device. The pre-separation method effectively reduces the risk that the pre-separation edge E of the film body 201 and the release film 202 cannot be torn from the film body 201 or the release film 202 is torn due to increased adhesion. It has been verified that the film tearing success rate of the release film 202 can reach 99.5%, which greatly improves the film tearing success rate of the release film 202. In addition, the scheme can reduce the equipment downtime, has high stability, basically does not need manual intervention, and reduces the waste of the protective film 200. In addition, the release film separation device can move the protective film 200 on the carrying platform 11 by the first robot, so as to facilitate the pre-separation of the next protective film 200 by the pre-separation device 100, thereby improving the production efficiency; and the first robot can cooperate with the film tearing mechanism to completely separate the pre-separated film body 201 and the release film 202, so as to complete the entire film tearing process of the protective film 200.

[0083] In one embodiment, referring to Figure 3The separating piece 21 comprises a protruding part 211 configured to protrude between the film body 201 and the release film 202.

[0084] In one example, the separating piece 21 comprises a main part and a protruding part 211 connected to the main part; the protruding part 211 is detachably connected to the main part; in this way, when the protruding part 211 is damaged or needs to be replaced or repaired, the protruding part 211 can be replaced, and the utilization rate of the main part can be improved, and the cost can be saved.

[0085] Of course, in other examples, the main part and the protruding part can be integrally formed, and there is no actual division between the two. In these examples, the part of the separating piece 21 configured to protrude into the protective film 200 can be defined as the protruding part 211.

[0086] It can be understood that the protruding part 211 referred to in the present embodiment is the end of the first end of the separating piece 21 described above.

[0087] In one example, the entire outer surface of the protruding part 211 is provided with the anti-adhesion structure. The anti-adhesion structure has an anti-adhesion property, and is used for anti-adhesion contact with the film body 201 and the release film 202. The anti-adhesion structure can be, but is not limited to, an anti-adhesion tape, an anti-adhesion plating layer, and the like.

[0088] In one example, the entire outer surface of the separating piece 21 is provided with the anti-adhesion structure; in this way, the setting mode of the anti-adhesion structure is relatively simple and fast.

[0089] In some examples, the movement rhythm of the separating piece 21 is 2 times / 30 seconds, 2400 times / day. That is, the separating piece 21 moves back and forth twice every 30 seconds, and moves back and forth 2400 times a day. The movement rhythm of the separating piece 21 is fast, and as the movement time increases, the adhesive layer on the protective film 200 will be left on the surface of the separating piece 21, which will affect the separation of the release film 202 and the film body 201; therefore, the separating piece 21 needs to be maintained regularly, for example, 3 times / day.

[0090] In the embodiment, the anti-sticking structure is arranged on the surface of the at least protruding part 211 of the separating member 21. During the protruding part 211 extending into the protective film 200, the anti-sticking structure can be in anti-sticking contact with the release film 202 and the protective film 200 respectively, thereby reducing the residual of the adhesive layer on the surface of the separating member 21, reducing the risk of the adhesive layer adhering to the protruding part 211, making the protruding part 211 difficult to extend into or out of the protective film 200, and making the protruding part 211 extend into or out of the protective film 200 smoothly. At the same time, the risk of the film body 201 being wrinkled or damaged due to adhesion with the protruding part 211 is reduced. In addition, the manual maintenance of the protruding part 211 can be reduced. For example, the maintenance period can be changed from 3 days / time to 30 days / time.

[0091] In an embodiment, the separating mechanism 20 is slidingly connected to the bearing mechanism 10 in a direction intersecting the bearing surface of the bearing platform 11.

[0092] As an example, the separating mechanism 20 is slidingly connected to the bearing mechanism 10 in a direction perpendicular to the bearing surface of the bearing platform 11. Compared with the scheme in which the sliding direction of the separating mechanism 20 is inclined relative to the bearing surface of the bearing platform 11, the sliding distance of the separating mechanism 20 can be shortened when the separating member 21 is adjusted to the same height relative to the bearing platform 11, thereby saving time and energy and accelerating the separation efficiency of the release film 202.

[0093] Of course, in other examples, the sliding direction of the separating mechanism 20 on the bearing mechanism 10 can also be inclined relative to the bearing surface of the bearing platform 11.

[0094] In the embodiment, by slidingly connecting the separating mechanism 20 to the bearing mechanism 10 in a direction intersecting the bearing surface of the bearing platform 11, the separating member 21 can be conveniently adjusted in height relative to the bearing surface of the bearing platform 11, so that the separating member 21 can extend more accurately between the release film 202 and the film body 201.

[0095] In an embodiment, in combination with Figure 2 The bearing mechanism 10 further comprises a support column 12, and the bearing platform 11 is arranged on the support column 12. The separating mechanism 20 further comprises a first driving member 22, which is connected with the separating member 21 and is configured to drive the separating member 21 to move in a direction parallel to the surface of the bearing platform 11, so as to extend into or out of the film body 201 and the release film 202. The first driving member 22 is slidingly connected to the support column 12 in the axial direction of the support column 12.

[0096] The surface of the bearing platform 11 refers to the bearing surface of the bearing platform 11 unless otherwise specified.

[0097] The number of support columns 12 is at least three, and the bearing platform 11 is arranged on the at least three support columns 12 to stably support the bearing platform 11. In an example, the number of support columns 12 is four, and the four support columns 12 can be distributed in a matrix.

[0098] The cross section of the support column 12 can be circular, square, polygonal, oval, or the like. As an example, the cross section of the support column 12 is circular, that is, the support column 12 is a cylinder; in this way, the first driving member 22 can slide on the support column 12.

[0099] The first driving member 22 can be, but is not limited to, a mechanical driving structure, a hydraulic driving structure, a pneumatic driving structure, an electric linear module, a synchronous belt module, a ball screw module, a chain module, or the like. In an example, the first driving member 22 specifically drives the separation member 21 to move back and forth along the first direction X.

[0100] In an example, in combination Figure 2 The separation member 21 is arranged on the side of the bearing platform 11 away from the support column 12 to reduce the interference of the bearing platform 11 with the movement of the separation member 21. The first driving member 22 is arranged on the side of the bearing platform 11 facing the support column 12 and is slidingly connected to the support column 12 along the axial direction of the support column 12.

[0101] In this example, the separation mechanism 20 further includes an adapter plate 23, one end of the adapter plate 23 is connected to the first driving member 22, and the other end of the adapter plate 23 is connected to the second end of the separation member 21. The first driving member 22 drives the separation member 21 to move along the first direction X through the adapter plate 23. In this way, the bearing platform 11 is neither in the sliding path of the first driving member 22 nor in the movement path of the separation member 21, which can effectively reduce the interference of the bearing platform 11 with the sliding process of the first driving member 22 and the movement process of the separation member 21.

[0102] In an example, the first driving member 22 includes a fixed part 221, which is detachably connected to the support column 12. When it is necessary to adjust the height of the separation member 21 relative to the bearing platform 11, the fixed part 221 can be detached from the support column 12 and re-fixed at another position of the support column 12 to meet the height requirement of the separation member 21. It can be understood that after the position of the fixed part 221 relative to the support column 12 changes, the separation member 21 can move together with the fixed part 221 to change the height of the separation member 21 relative to the bearing surface of the bearing platform 11.

[0103] In this example, the first driving member 22 can include two fixed parts 221, which are respectively detachably connected to two support columns 12 to increase the stability of the height of the first driving member 22 relative to the bearing platform 11.

[0104] In one example, the fixing part 221 can include a first sleeving part 222, a second sleeving part 223, and a fixing member (not shown in the figure). The first sleeving part 222 and the second sleeving part 223 are oppositely arranged along the radial direction of the support column 12, and the first sleeving part 222 has a first groove which is matched with the profile of the first part of the support column 12 and is arranged in close contact with the first part of the support column 12. The second sleeving part 223 has a second groove which is matched with the profile of the second part of the support column 12 which is different from the first part and is arranged in close contact with the second part of the support column 12. The fixing member is connected with the first sleeving part 222 and the second sleeving part 223 respectively to stably fix the first sleeving part 222 and the second sleeving part 223 on the support column 12. When it is needed to adjust the height of the separating part 21 relative to the bearing platform 11, the fixing member can be loosened or removed so that the first sleeving part 222 and the second sleeving part 223 can move up and down along the axial direction of the support column 12. When the first sleeving part 222 and the second sleeving part 223 are moved to the preset position of the support column 12, the fixing member is tightened again to fix the first sleeving part 222 and the second sleeving part 223 at the preset position of the support column 12.

[0105] Of course, in other examples, one of the support column 12 and the fixing part 221 can be provided with a sliding rail, and the other one can have a sliding block which is embedded in the sliding rail and can move back and forth in the sliding rail to achieve the sliding connection of the first driving part 22 on the support column 12. For example, the support column 12 has a sliding rail along the axial direction thereof, and the fixing part 221 is a sliding block which is embedded in the sliding rail and can slide back and forth along the extension direction of the sliding rail.

[0106] In some examples, in combination with Figure 2 The bearing mechanism 10 further includes a bottom plate 13, and the plurality of support columns 12 are respectively connected to the bottom plate 13 to improve the balance and stability of the bearing mechanism 10. For example, the bottom plate 13 is oppositely arranged with the bearing platform 11, and the plurality of support columns 12 are located between the bearing platform 11 and the bottom plate 13.

[0107] In this embodiment, the first driving part 22 is used to drive the movement of the separating part 21, which has a high degree of automation and can more accurately control the length of the separating part 21 extending into the protective film 200 along the first direction X, thereby reducing the risk of wrinkles of the film body 201 or the film body 201 being lifted by the separating part 21. In addition, the first driving part 22 is slidingly connected to the support column 12 to achieve the sliding connection of the separating mechanism 20 and the bearing mechanism 10, which has a simple structure, is easy to operate, and does not interfere with the movement process of the separating part 21 nor occupies the area of the bearing platform 11.

[0108] In one embodiment, in combination with Figures 2 to 5The pre-separating device 100 further comprises a fixing mechanism 30 connected to the bearing mechanism 10 and configured to fix the side where the pre-separating edge E of the release film 202 is located on the bearing platform 11.

[0109] Referring to Figure 3 The fixing mechanism 30 specifically acts on the part of the release film 202 beyond the film body 201 to fix the release film 202 on the bearing platform 11. That is, the fixing mechanism 30 specifically fixes the overhanging part of the release film 202 on the bearing platform 11.

[0110] The fixing mechanism 30 can press and adsorb the release film 202 on the bearing platform 11, or clamp the release film 202 between the fixing mechanism 30 and the bearing platform 11, etc. to fix the side where the pre-separating edge E of the release film 202 is located on the bearing platform 11.

[0111] The fixing mechanism 30 can be connected to the bearing platform 11 or the support column 12. Of course, the fixing mechanism 30 can also be connected to the bearing platform 11 and the support column 12 respectively. It can be understood that when the connection between the support column 12 and the bearing platform 11 loosens, the fixing stability of the fixing mechanism 30 to the release film 202 can also change. Therefore, in one example, the fixing mechanism 30 is connected to the bearing platform 11, so that the influence of the connection performance between the support column 12 and the bearing platform 11 on the fixing stability of the fixing mechanism 30 to the release film 202 can be effectively reduced, and the fixing stability of the fixing mechanism 30 to the side where the pre-separating edge E of the release film 202 is located can be effectively improved.

[0112] In one example, the separating piece 21 can be combined with Figure 3 In order to reduce the risk of hindering the movement of the separating piece 21 by the fixing mechanism 30, the size of the separating piece 21 along the second direction Y can be smaller than the size of the protective film 200 along the second direction Y. In this example, the separating piece 21 can be further moved along the second direction Y to separate the pre-separating edge E of the protective film 200 along the second direction Y as much as possible.

[0113] As an example, the ratio of the size of the separating piece 21 along the second direction Y to the size of the protective film 200 along the second direction Y can be greater than or equal to 0.2 and less than or equal to 0.9. For example, the ratio of the size of the separating piece 21 along the second direction Y to the size of the protective film 200 along the second direction Y can be greater than or equal to 0.3 and less than or equal to 0.6. For example, the ratio of the size of the separating piece 21 along the second direction Y to the size of the protective film 200 along the second direction Y can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or 0.9, etc.

[0114] Of course, if the fixing mechanism 30 fixes the release film 202 in a manner that avoids the moving path of the separating piece 21, the size of the separating piece 21 in the second direction Y can be greater than or equal to the size of the protective film 200 in the second direction Y, so that the entire pre-separation edge E of the protective film 200 in the second direction Y can be pre-separated during each movement.

[0115] In the embodiment, by arranging the fixing mechanism 30, the risk of movement of the release film 202 relative to the bearing platform 11 and the risk of the release film 202 being lifted by the separating piece 21 can be reduced during the pre-separation of the film body 201 and the release film 202, thereby improving the pre-separation effect.

[0116] In one embodiment, in combination with Figures 2 to 5 The fixing mechanism 30 includes a second driving piece 31 and a pressing block 32. The second driving piece 31 is connected to the bearing mechanism 10. The pressing block 32 is connected to the second driving piece 31, and the second driving piece 31 is configured to drive the pressing block 32 to move in the height direction Z of the bearing mechanism 10 towards or away from the bearing platform 11, so as to press or release the release film 202.

[0117] In one example, the second driving piece 31 is connected to the bearing platform 11. The second driving piece 31 can be, but is not limited to, a mechanical driving structure, a hydraulic driving structure, a pneumatic driving structure, an electric linear module, a synchronous belt module, a ball screw module, a chain module, etc.

[0118] In a specific working process, the second driving piece 31 drives the pressing block 32 to move towards the bearing platform 11 to press the release film 202 onto the bearing platform 11. The second driving piece 31 drives the pressing block 32 to move away from the bearing platform 11 to release the release film 202.

[0119] The pressing block 32 is specifically configured to apply a force to the part of the release film 202 that exceeds the film body 201 (i.e., the excess part), so as to press the release film 202 onto the bearing platform 11 and reduce the risk of movement of the release film 202. The pressing block 32 can be a rectangular block, a square block, etc.

[0120] The surface of the pressing block 32 that is configured to contact the release film 202 is parallel to the bearing surface of the bearing platform 11 and is a flat surface. The flat surface means that the flatness of the surface relative to a reference plane is within a predetermined range, which can be greater than or equal to 2 mm and less than or equal to 3 mm. The flatness refers to the maximum difference in distance between each point on the surface and the reference plane.

[0121] In this embodiment, the release film 202 can be directly pressed on the bearing platform 11 by the pressing block 32, which is convenient and fast to operate; and compared with the way of fixing the release film 202 and the bearing platform 11 in sequence by the clamping or fixing member, the damage to the release film 202 and the bearing platform 11 is smaller.

[0122] In one embodiment, the pressing block 32 is an elastic block; or the pressing block 32 is provided with an elastic pad on the side surface facing the bearing platform 11.

[0123] The elastic block or the elastic pad is a structural member made of an elastic material. The elastic block can be, but is not limited to, a plastic block or a rubber block, etc. The elastic pad can be, but is not limited to, a plastic pad or a rubber pad.

[0124] In one example, the pressing block 32 is an elastic block, i.e., the material of the pressing block 32 is an elastic material. In another example, the pressing block 32 includes a pressing block body and an elastic pad, the elastic pad is arranged on the side surface of the pressing block body facing the bearing platform 11, and the elastic pad is configured to contact the release film 202. The material of the pressing block body can not be limited; for example, the pressing block body can be a metal block to improve the pressing force of the pressing block 32 on the release film 202.

[0125] As an example, the elastic block can be a super elastic block. The elastic pad can be a super elastic pad.

[0126] In this embodiment, by making the pressing block 32 an elastic block or providing the pressing block 32 with an elastic pad on the side surface facing the bearing platform 11, the friction between the pressing block 32 and the release film 202 can be increased, thereby reducing the risk of relative displacement between the pressing block 32 and the release film 202. At the same time, the pressing block 32 contacts the surface of the release film 202 through the elastic structure, and since the material of the elastic structure is soft, the risk of damage to the release film 202 can be reduced, and the risk of rupture of the release film 202 during the pre-separation process can be reduced.

[0127] Referring to Figure 6 , Figure 6 The overall structure schematic diagram of the release film separation device provided by an embodiment of the present application is shown.

[0128] In one embodiment, the release film separation device further includes a sensor 40 arranged on the bearing platform 11 and electrically connected with the second driving member 31; the sensor 40 is configured to sense the protective film 200 and send a pressing signal in response to sensing the protective film 200; and the second driving member 31 drives the pressing block 32 to move towards the bearing platform 11 in response to the pressing signal.

[0129] The sensor 40 can be a sensor. After the protective film 200 is placed on the bearing platform 11, the sensor 40 detects the protective film 200 and sends a pressing signal. The second driving member 31 receives the pressing signal and starts working to drive the pressing block 32 to move towards the bearing platform 11, so as to press the release film 202 tightly on the bearing platform 11.

[0130] In this embodiment, the sensor 40 can automatically sense whether the protective film 200 is placed on the bearing platform 11, and automatically control the pressing block 32 to move downward to press the release film 202 when the protective film 200 is placed on the bearing platform 11. The degree of automation of this scheme is high, and the separation efficiency of the release film 202 can be effectively improved.

[0131] In one embodiment, the second driving member 31 drives the pressing block 32 to move away from the bearing platform 11 in response to the number of times the separating member 21 extends into the film body 201 and the release film 202 reaching a preset number of times.

[0132] The preset number of times can be set according to actual conditions. For example, the preset number of times can be two, three or more.

[0133] In this embodiment, the pressing block 32 can be automatically controlled to move away from the bearing platform 11 to release the release film 202, which can further improve the separation efficiency of the release film 202. In addition, the pressing block 32 is driven to release the release film 202 only after the number of times the separating member 21 extends into the film body 201 and the release film 202 reaches a preset number of times, which can reduce the risk of the pre-separation edge E of the film body 201 and the release film 202 being bonded together without being well separated, and effectively improve the separation effect of the pre-separation edge E of the film body 201 and the release film 202.

[0134] In one embodiment, in combination with Figure 2 and Figure 3 , the number of the fixing mechanism 30 is two, and the two fixing mechanisms 30 are located on the same side of the bearing platform 11 along the first direction X of the bearing platform 11; the two fixing mechanisms 30 are configured to fix the two ends of the side where the pre-separation edge E of the release film 202 is located on the bearing platform 11.

[0135] The two fixing mechanisms 30 have the same structure and function.

[0136] In one example, the two fixing mechanisms 30 are respectively arranged at positions close to the edges of the two sides of the bearing platform 11 along the second direction Y, and are respectively configured to fix the two ends of the side where the pre-separation edge E of the release film 202 along the second direction Y is located.

[0137] Exemplarily, the normal projection of the pressing blocks 32 of the two fixing mechanisms 30 on the bearing platform 11 is located at the same side edge of the bearing platform 11 along the first direction X and is located at the positions close to the edges of the bearing platform 11 along the second direction Y.

[0138] In this embodiment, the side of the release film 202 where the pre-separation edge E is located is fixed by the two fixing mechanisms 30, which can improve the stability of the relative position of the release film 202 on the bearing platform 11 and the bearing platform 11, reduce the risk of movement of the release film 202 relative to the bearing platform 11 during the pre-separation process, and thus effectively improve the pre-separation effect.

[0139] In one embodiment, in combination with Figure 2 and Figure 3 , the two fixing mechanisms 30 are located on both sides of the separation piece 21 along the second direction Y; the second direction Y is perpendicular to the first direction X.

[0140] Exemplarily, the pressing blocks 32 of the two fixing mechanisms 30 are located on both sides of the separation piece 21 along the second direction Y, that is, the separation piece 21 is located between the pressing blocks 32 of the two fixing mechanisms 30 along the second direction Y. Since the separation piece 21 moves along the first direction X, the two pressing blocks 32 move along the direction perpendicular to the surface of the bearing platform 11. Therefore, this scheme can effectively reduce the interference of the two fixing mechanisms 30 on the movement of the separation piece 21 along the first direction X.

[0141] In one embodiment, please refer to Figure 6 , the bearing platform 11 is provided with suction accessories 50 configured to suction the protective film 200 from the side surface of the protective film 200 towards the bearing platform 11.

[0142] The number of suction accessories 50 can be multiple, and the multiple suction accessories 50 are arranged on the bearing platform 11 in a spaced manner to suction and fix each position of the protective film 200 on the bearing platform 11. Exemplarily, the multiple suction accessories 50 can be distributed in a matrix on the bearing platform 11. Alternatively, the multiple suction accessories 50 are uniformly distributed on the bearing platform 11 to balance the suction force on each position of the protective film 200, thereby reducing the risk of tearing of the protective film 200 due to uneven force during the process of grabbing the protective film 200 by the first robot (see below).

[0143] The suction accessory 50 can be a suction disc. Of course, the suction accessory 50 can also be a vacuum suction hole which can be communicated with a gas pressure control end (not shown in the figure). The gas pressure control end can perform air extraction operation on the vacuum suction hole to vacuum suction the protective film 200 to the bearing platform 11. Conversely, the gas pressure control end can perform air supply operation on the vacuum suction hole to weaken the vacuum suction force and break the vacuum state, so as to facilitate the protective film 200 to separate from the bearing platform 11.

[0144] In this embodiment, the protective film 200 can be fixed on the bearing platform 11 by the suction accessory 50, reducing the risk of the protective film 200 moving or falling off the bearing platform 11. Meanwhile, the suction accessory 50 is combined with the pressing block 32 to fix the protective film 200 from the upper and lower surfaces of the protective film 200 respectively, which can further reduce the risk of the protective film 200 moving relative to the bearing platform 11, thereby effectively improving the pre-separation effect of the film body 201 and the release film 202.

[0145] The process of separating the release film 202 by the release film separation device will be described below.

[0146] The second robot places the protective film 200 on the bearing platform 11 and sets the release film 202 towards the bearing platform 11. The suction accessory 50 on the bearing platform 11 sucks the release film 202 tightly. After the sensor 40 detects the release film 202, the second driving member 31 drives the pressing block 32 to descend and press the part of the release film 202 beyond the film body 201 tightly. After the second driving member 31 drives the pressing block 32 to press the release film 202, the first driving member 22 drives the separation member 21 to start moving, so that the separation member 21 extends into the space between the film body 201 and the release film 202, and then retracts, and such repeated actions are performed for a preset number of times, so as to pre-separate the pre-separation edge E of the film body 201 and the release film 202. After the number of times that the separation member 21 extends into the space between the film body 201 and the release film 202 reaches the preset number of times, the second driving member 31 drives the pressing block 32 to ascend, so as to release the release film 202. Then, the first robot sucks the film body 201 and moves the protective film 200 to the film tearing mechanism. The film tearing mechanism grabs the part of the release film 202 beyond the film body 201 and moves relative to the first robot until the film body 201 and the release film 202 are completely separated, thereby completing the separation of the current release film 202.

[0147] In some embodiments, a film pasting system is also provided, which includes the above-mentioned release film separation device and the film pasting device. In this embodiment, after the film body 201 and the release film 202 are completely separated, the first robot can further carry the film body 201 to the film pasting device to complete the film pasting process by the film pasting device.

[0148] The film pasting device is a device that can be used to implement the film pasting operation. In some embodiments, the film pasting device can be a film pasting robot, which can be a six-axis industrial robot.
