Description

Technical Field

[0001] This utility model relates to the field of automatic vehicle changing, specifically to a high-precision automatic vehicle changing device with flexible circuit boards. Background Technology

[0002] In the production of flexible circuit boards, due to the various characteristics of the product, carriers are often required for loading the product. Since different carriers are often used for different processes to achieve streamlined production, carrier turnover is also involved.

[0003] The production of flexible circuit boards requires the use of adhesive application carriers and bending carriers. Products can be placed face-up or face-down in the adhesive application carrier, while the bending carrier only allows for face-up placement. During the transfer of products from the adhesive application carrier to the bending carrier, face-up products can be transferred directly, while face-down products must be flipped before transfer. Due to these requirements for product transfer and flipping, the workload for operators is significant during carrier turnover, and the risk of product damage is also increased.

[0004] Products are generally covered with a blue film. Considering that the blue film will affect the subsequent production process, it must be removed before the product is placed into the bending carrier, which further increases the workload of the operators.

[0005] Therefore, how to solve the problem of the large workload of operators caused by the turnover of the vehicle in the existing technology has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a high-precision automatic carrier changing device for flexible circuit boards.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A high-precision automatic carrier changing device for flexible circuit boards is used to transfer products between an adhesive application carrier and a bending carrier. The adhesive application carrier includes an adhesive application support and a carrier cover, and the bending carrier includes a bending support and a pressing steel sheet. The high-precision automatic carrier changing device for flexible circuit boards includes:

[0009] frame;

[0010] An adhesive application carrier conveyor line, located on the frame, is used to transport and position the adhesive application carrier;

[0011] A bending carrier conveyor line, located on the frame, is used to transport and position the bending carrier;

[0012] The cover opening assembly is positioned close to the adhesive application carrier conveyor line and is used to separate the carrier cover from the adhesive application carrier;

[0013] A handling and flipping assembly, located on the frame, is used to handle the carrier cover after it has been separated from the adhesive carrier, and also to flip the product;

[0014] A product transfer assembly, located on the frame, is used to transfer products initially on the adhesive application carrier to the bending carrier.

[0015] A film removal assembly, located on the frame, is used to remove the blue film from the product during the product transfer process by the product transfer assembly.

[0016] A steel sheet transfer assembly, disposed on the frame, is used to transfer the press-fit steel sheet before the product transfer assembly transfers the product into the bending carrier, and is also used to reset the press-fit steel sheet after the product is transferred into the bending carrier.

[0017] In the above scheme, the sequence of carrier turnover is as follows: the adhesive application carrier flows from the front station to the opening area via the adhesive application carrier conveyor line; then, the opening component separates the carrier cover from the adhesive application carrier; subsequently, the handling and flipping component removes the carrier cover and places it in the carrier cover placement area (set on the adhesive application carrier or frame); then, the product transfer component removes the forward or reverse product, and before removing the reverse product, the handling and flipping component flips the reverse product; during the product transfer process, the film removal component works with the product transfer component to remove the blue film on the product; before the product is placed, the bending carrier flows in via the bending carrier conveyor line; after the bending carrier is in place, the steel sheet transfer component removes the pressing steel sheet; subsequently, the product transfer component places the product on the bending carrier; finally, the steel sheet transfer component resets the pressing steel sheet to fix the product, the handling and flipping component also resets the carrier cover, and then the adhesive application carrier and bending carrier flow out.

[0018] With the above settings, the product's handling between different carriers and the flipping operation before handling are all automated, thereby replacing manual operation, reducing labor input, reducing the workload of operators, and reducing the risk of product damage during flipping and handling due to high efficiency and stability.

[0019] A further technical solution includes vision components on the sides of both the adhesive application carrier conveyor line and the bending carrier conveyor line; the two vision components can be used to take pictures of the adhesive application carrier and the bending carrier respectively, so as to facilitate the precise positioning and conveying of the adhesive application carrier and the bending carrier by the adhesive application carrier conveyor line and the bending carrier respectively; the two vision components can also be used to accurately position the product after the product transfer component picks up the product so as to accurately place the product on the predetermined position on the bending carrier.

[0020] It can be used in conjunction with existing controllers and other control devices and vision components, or with structures such as adhesive application carrier conveyor lines, with the aim of achieving automation, specifically by transmitting signals or information. This is a standard setting and will not be elaborated here.

[0021] Optionally, a re-inspection camera is provided on the side of the steel sheet transfer assembly. The re-inspection camera is used to detect whether the product is placed on the bending carrier accurately, so as to avoid damage to the product caused by the pressed steel sheet due to inaccurate placement.

[0022] In a further technical solution, the adhesive application carrier conveyor line and the bending carrier conveyor line are arranged parallel to each other along the width direction of the adhesive application carrier conveyor line or the bending carrier conveyor line.

[0023] Compared to the arrangement of the adhesive application carrier conveyor line and the bending carrier conveyor line along the length of the adhesive application carrier conveyor line or the bending carrier conveyor line, the arrangement in this embodiment can reduce the space occupied by this application and facilitate bidirectional transportation of the adhesive application carrier and the bending carrier by the adhesive application carrier conveyor line and the bending carrier by the bending carrier respectively. At the same time, the product transfer component can be set between the adhesive application carrier conveyor line and the bending carrier conveyor line, which is conducive to the transfer of products by the product transfer component.

[0024] In a further technical solution, the high-precision automatic carrier changing device for flexible circuit boards also includes a bending carrier return conveyor line disposed on the frame; the bending carrier return conveyor line and the bending carrier conveyor line are arranged vertically and parallel to each other in the length direction.

[0025] Here, we will describe a scenario where a bending carrier return conveyor is positioned below the bending carrier conveyor. The bending carrier is fed into the bending carrier conveyor from a predetermined position along a predetermined direction (hereinafter referred to as the first direction). After the product is loaded into the bending carrier, the bending carrier is sent into the bending carrier return conveyor. The bending carrier return conveyor conveys the bending carrier in the opposite direction to the first direction to transport the bending carrier below the predetermined position. This avoids affecting the subsequent feeding of bending carriers into the bending carrier conveyor and allows the bending carrier to be transferred to an area close to the predetermined position for convenient subsequent processing.

[0026] In a further technical solution, the handling and flipping assembly includes a rotary drive, a support, a clamping component, and a suction component; the support is mounted on the rotary drive; both the clamping component and the suction component are mounted on the support; the rotary drive can achieve positional interchange between the clamping component and the suction component through the support.

[0027] Here, we will explain from top to bottom. Initially, since it is necessary to move the top cover of the carrier and the front-facing products need to be moved first, the clamping component is located below the suction component for a certain period of time. When it is necessary to move the reverse-facing products later, the clamping component and the suction component switch positions, and the suction component picks up the products. Then the clamping component and the suction component switch positions again to flip the products.

[0028] When handling front-side products, the product transfer component directly handles the transfer, meaning the product transfer component takes the front-side product from the adhesive carrier. When handling back-side products, the back-side product is first flipped over using the above method, and then the product transfer component takes the back-side product from the suction unit.

[0029] In a further technical solution, the handling and flipping assembly also includes a support column and a drive unit; the support column is disposed on the frame; the rotary drive component is connected to the support column through the drive unit; the drive unit can drive the rotary drive component to move in the vertical and horizontal directions.

[0030] The clamping and suction components share the same rotary drive and drive unit, and the clamping and suction components have the same degree of freedom of movement. This design simplifies the structure and saves space.

[0031] In a further technical solution, the film removal assembly includes a film suction member and a clamping part both disposed on the frame; the film suction member is used to promote the movement of a portion of the blue film toward the clamping part; the clamping part is used to automatically clamp the blue film and cooperate with the product transfer assembly to remove the blue film from the product.

[0032] During the product transfer process, the suction component applies suction to the blue film, causing the blue film to have several raised sections. Subsequently, the clamping part clamps some of the raised sections. In the subsequent process, the product transfer component continues to move the product and the blue film closer to the bending carrier, while the blue film is confined within a certain range. Therefore, the blue film gradually separates from the product.

[0033] The clamping part works with the product transfer component to remove the blue film on the product, preventing the blue film from affecting the subsequent production process. The suction part ensures both the film removal effect and the film removal progress. Compared with the existing automatic blue film removal structure design, the structure is simplified.

[0034] A further technical solution is that the film suction component has multiple film suction ports that can move vertically.

[0035] The suction port of the film suction device generates suction to attract the blue film. The suction port can be moved vertically to adjust the suction effect.

[0036] It should be noted that there is suction at the suction port. After the blue film is torn, the suction port rises and the clamping part releases its grip on the blue film, which is then sucked away and collected by the suction port.

[0037] In a further technical solution, the clamping part includes multiple gripper cylinders.

[0038] A further technical solution is that the steel sheet transfer assembly includes a moving mechanism disposed on the frame, two variable pitch cylinders mounted on the moving mechanism, and two suction cup structures respectively disposed on the two variable pitch cylinders; the variable pitch cylinders are driven by the moving mechanism and have two degrees of freedom of movement in the horizontal and vertical directions respectively.

[0039] When not in operation, there is a first gap between the two suction cup structures and between the two pressing steel sheets. When in operation, due to the adjustment of the two variable pitch cylinders, there is a second gap between the two suction cup structures and between the two pressing steel sheets. The second gap is greater than the first gap. By adjusting the gap, the two pressing steel sheets can press the product simultaneously.

[0040] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0041] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0042] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0043] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0044] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0045] The working principle and advantages of this utility model are as follows:

[0046] During carrier turnover, the adhesive application carrier flows from the previous station to the opening area via the adhesive application carrier conveyor line. Next, the opening assembly separates the carrier cover from the adhesive application carrier. Then, the handling and flipping assembly removes the carrier cover and places it in the carrier cover placement area. Next, the product transfer assembly removes the forward or reverse product; before removing the reverse product, the handling and flipping assembly flips the reverse product. During product transfer, the film removal assembly works with the product transfer assembly to remove the blue film from the product. Before the product is placed, the bending carrier flows in via the bending carrier conveyor line. After the bending carrier is in place, the steel sheet transfer assembly removes the pressing steel sheet. After removing the pressing steel sheet, the product transfer assembly places the product onto the bending carrier. Finally, the steel sheet transfer assembly resets the pressing steel sheet to secure the product, and the handling and flipping assembly also resets the carrier cover. Then, the adhesive application carrier and bending carrier flow out. With the above settings, the product's handling between different carriers and the flipping operation before handling are all automated, thereby replacing manual operation, reducing labor input, reducing the workload of operators, achieving high-precision handling, and reducing the risk of product damage during flipping and handling due to high efficiency and stability.

[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0058] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0059] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0060] See Figures 1-9 A high-precision automatic carrier changing device for flexible circuit boards is used to transfer products between an adhesive application carrier 1 and a bending carrier 2. The adhesive application carrier 1 includes an adhesive application support and a carrier cover, and the bending carrier 2 includes a bending support and a pressing steel sheet. The high-precision automatic carrier changing device for flexible circuit boards includes:

[0061] Rack 3;

[0062] The adhesive application carrier conveyor line 4 is located on the frame 3 and is used to transport and position the adhesive application carrier 1;

[0063] The bending carrier conveyor line 5 is located on the frame 3 and is used to transport and position the bending carrier 2;

[0064] The cover opening assembly is positioned close to the adhesive application carrier conveyor line 4 and is used to separate the carrier cover from the adhesive application carrier;

[0065] The handling and flipping assembly 7 is located on the frame 3 and is used to handle the carrier cover after it has been separated from the adhesive carrier, and also to flip the product.

[0066] Product transfer assembly 8, located on the frame 3, is used to transfer products initially on the adhesive application carrier 1 onto the bending carrier 2;

[0067] The film removal assembly 9 is disposed on the frame 3 and is used to remove the blue film on the product during the product transfer assembly 8 transfers the product.

[0068] The steel sheet transfer assembly 10 is disposed on the frame 3 and is used to transfer the press-fit steel sheet before the product transfer assembly 8 transfers the product into the bending carrier 2, and also to reset the press-fit steel sheet after the product is transferred into the bending carrier 2.

[0069] Products placed face up are referred to as front products, and products placed face down are referred to as back products. Products include both front and back products.

[0070] The adhesive application carrier 1 consists of an adhesive application carrier and a carrier cover. Initially, multiple front and back products are placed on the adhesive application carrier, and the carrier cover covers one or more products. The carrier cover can later be transferred to other areas on the adhesive application carrier or other areas of the frame 3.

[0071] The sequence of carrier turnover is as follows: The adhesive application carrier 1 flows from the previous station into the opening area via the adhesive application carrier conveyor line 4; then, the opening assembly (not shown in the figure) separates the carrier cover from the adhesive application carrier; subsequently, the handling and flipping assembly 7 removes the carrier cover and places it in the carrier cover placement area (located on the adhesive application carrier or frame 3); then, the product transfer assembly 8 removes the forward or reverse product, and before removing the reverse product, the handling and flipping assembly 7 flips the reverse product; during the product transfer... During the transfer process, the film removal component 9 works with the product transfer component 8 to remove the blue film from the product; before the product is placed, the bending carrier 2 flows in via the bending carrier conveyor line 5; after the bending carrier 2 is in place, the steel sheet transfer component 10 removes the pressing steel sheet; subsequently, the product transfer component 8 places the product onto the bending carrier; finally, the steel sheet transfer component 10 resets the pressing steel sheet to fix the product, and the handling and flipping component 7 also resets the carrier cover. Then, the adhesive application carrier 1 and the bending carrier 2 flow out.

[0072] With the above settings, the product's handling between different carriers and the flipping operation before handling are all automated, thereby replacing manual operation, reducing labor input, reducing the workload of operators, achieving high-precision handling, and reducing the risk of product damage during flipping and handling due to high efficiency and stability.

[0073] The adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5 are existing conveyor lines, which generally use conveyors and other devices, and are not specifically limited here.

[0074] The following supplementary information is provided for the cover opening component: There are several holes on the adhesive carrier, some of which are for the cover opening component to pass through in order to lift the cover of the carrier; the cover opening component can adopt an existing lifting structure such as a cylinder.

[0075] See Figure 1 In this embodiment, both the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5 are equipped with vision components (not shown in the figure) on their sides. The two vision components can be used to take pictures of the adhesive application carrier 1 and the bending carrier 2 respectively, so as to facilitate the precise positioning and conveying of the adhesive application carrier 1 and the bending carrier 2 by the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5 respectively. The two vision components can also be used to accurately position the product after the product transfer component 8 picks up the product so as to accurately place the product on the predetermined position on the bending carrier 2.

[0076] Optionally, the vision component includes a camera and a light source. Vision components are prior art and well-known to those skilled in the art, and will not be described in detail here.

[0077] The position and support settings in this application are illustrated using a vision component as an example, as follows: The vision component is supported during use. It can be supported by the frame 3 or the conveyor line, or a support column can be set on the top of the frame 3 for support. The support is a conventional setting and will not be described in detail here. Taking the adhesive application carrier conveyor line 4 as an example, one vision component is set on the periphery of the adhesive application carrier conveyor line 4. For example, the vision component can be set on any side of the adhesive application carrier conveyor line 4 along the width direction of the adhesive application carrier conveyor line 4. There are no specific limitations here.

[0078] Taking the adhesive application carrier conveyor line 4 and the adhesive application carrier 1 as an example, the adhesive application carrier 1 moves on the adhesive application carrier conveyor line 4. Here, an open area is set up for explanation. The vision component takes a picture of the open area for detection. When the adhesive application carrier 1 enters the open area, the vision component detects this situation and then transmits the information to the adhesive application carrier conveyor line 4. Subsequently, the adhesive application carrier conveyor line 4 stops conveying the adhesive application carrier 1, realizing the precise positioning and conveying of the adhesive application carrier 1 by the adhesive application carrier conveyor line 4.

[0079] It can be used in conjunction with existing controllers and other control devices and vision components, or it can be used in conjunction with structures such as adhesive application carrier conveyor line 4, with the purpose of achieving automation, specifically the transmission of signals or information. This is a conventional setting and will not be explained in detail here.

[0080] Optionally, a re-inspection camera 11 is provided on the side of the steel sheet transfer assembly 10. The re-inspection camera 11 is used to detect whether the product is accurately placed on the bending carrier, so as to avoid damage to the product caused by the pressed steel sheet due to inaccurate placement. The re-inspection camera 11 can be connected to an existing electric slide table to adjust the detection range of the re-inspection camera 11.

[0081] See Figure 2In this embodiment, the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5 are arranged in parallel along the width direction of the adhesive application carrier conveyor line 4 or the bending carrier conveyor line 5.

[0082] Compared to the arrangement of the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5 along the length of the adhesive application carrier conveyor line 4 or the bending carrier conveyor line 5, the arrangement in this embodiment can reduce the space occupied by this application and facilitate the bidirectional transportation of the adhesive application carrier 1 and the bending carrier 2 by the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5 respectively. At the same time, the product transfer component 8 can be arranged between the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5, which is conducive to the transfer of products by the product transfer component 8.

[0083] See Figure 2 In this embodiment, the high-precision automatic carrier changing device for flexible circuit boards further includes a bending carrier return conveyor line 12 disposed on the frame 3; the bending carrier return conveyor line 12 and the bending carrier conveyor line 5 are arranged vertically and parallel to each other in the length direction.

[0084] Here, we will describe a bending carrier return conveyor line 12 located below the bending carrier conveyor line 5. The bending carrier 2 is fed into the bending carrier conveyor line 5 from a predetermined position along a predetermined direction (hereinafter referred to as the first direction). After the product is loaded into the bending carrier 2, the bending carrier 2 is fed into the bending carrier return conveyor line 12. The bending carrier return conveyor line 12 conveys the bending carrier 2 in a direction opposite to the first direction to transport the bending carrier 2 below the predetermined position. This avoids affecting the subsequent feeding of the bending carrier 2 into the bending carrier conveyor line 5 and allows the bending carrier 2 to be transferred to an area close to the predetermined position for convenient subsequent processing.

[0085] A return elevator can be installed between the bending carrier conveyor line 5 and the bending carrier return conveyor line 12, thereby facilitating the transfer of the bending carrier 2 between the bending carrier conveyor line 5 and the bending carrier return conveyor line 12.

[0086] It should be noted that the bending carrier 2 can also be fed into the bending carrier return conveyor line 12 first and then transferred to the bending carrier conveyor line 5. The specific method is the same as described above. The setting of the bending carrier return conveyor line 12 is also the same as the setting of the bending carrier conveyor line 5.

[0087] See Figure 4 , Figure 5 In this embodiment, the handling and flipping assembly 7 includes a rotary drive 71, a support 72, a clamping member 73, and a suction member 74; the support 72 is mounted on the rotary drive 71; the clamping member 73 and the suction member 74 are both mounted on the support 72; the rotary drive 71 can achieve the interchange of the positions of the clamping member 73 and the suction member 74 through the support 72.

[0088] Optionally, the rotary drive 71 is configured as a rotary cylinder.

[0089] Optionally, the clamping element 73 can be configured as a clamp, such as an electric clamp, which is an existing configuration and will not be described in detail here.

[0090] Optionally, the suction component 74 is configured as an existing vacuum adsorption setup with a suction cup. Vacuum adsorption is a prior art technique, and will be described in detail below for ease of understanding: The vacuum adsorption device mainly consists of a vacuum suction cup, a vacuum generating device (such as a vacuum pump), connecting pipes, and possible control elements (such as a pressure control valve). After the vacuum generating device is activated, air is evacuated from the inside of the suction cup through the connecting pipes, creating a negative pressure inside the suction cup. Because a negative pressure is created inside the suction cup, while the outside pressure remains atmospheric, a pressure difference is generated between the suction cup and the object being adsorbed. Under the action of this pressure difference, products such as flexible circuit boards are pressed onto the suction cup, thereby achieving the adsorption effect. All adsorption-capable components in this application can be described with reference to this description.

[0091] Here, we will explain from top to bottom. Initially, since it is necessary to move the top cover of the carrier and the front-facing product needs to be moved first, the clamping member 73 is located below the suction member 74 for a certain period of time. When it is necessary to move the reverse-facing product later, the clamping member 73 and the suction member 74 switch positions, and the suction member 74 picks up the product. Then the clamping member 73 and the suction member 74 switch positions again to flip the product.

[0092] In some cases, the clamp 73 may not need to transfer the vehicle cover to the placement area, while in other cases, such as when the vehicle cover is not clamped to avoid deformation, it needs to be transferred to the placement area to prevent it from falling off during the flipping process.

[0093] When handling the front-side product, the product transfer component 8 directly handles the product, that is, the product transfer component 8 takes the front-side product from the adhesive carrier; when handling the back-side product, the back-side product is first flipped over in the above manner, and then the product transfer component 8 takes the back-side product from the suction member 74.

[0094] Optionally, the product transfer component 8 includes a suction structure and a moving structure; the suction structure can be configured as the vacuum adsorption setup with suction cups described above; the moving structure enables the suction structure to move in the x, y, and z axes. For example, the moving structure can be configured as three sequentially connected electric slides, which is a conventional setup and will not be described in detail here.

[0095] It should be emphasized that, considering the weight difference between the carrier cover and the product, both are fixed using clamping and adsorption devices respectively. These fixing devices can be adjusted according to the actual weight of the two, such as using adsorption devices to fix the carrier cover.

[0096] See Figure 4 , Figure 5 In this embodiment, the handling and flipping assembly 7 further includes a support column 75 and a drive unit 76; the support column 75 is disposed on the frame 3; the rotary drive member 71 is connected to the support column 75 through the drive unit 76; the drive unit 76 can drive the rotary drive member 71 to move in the vertical and horizontal directions.

[0097] Optionally, the drive unit 76 includes two connected electric slides. Under the action of the drive unit 76, the rotary drive member 71 has two degrees of freedom of movement in the vertical direction and two degrees of freedom of movement in the horizontal direction.

[0098] The rotary drive 71 has two degrees of freedom of movement in the vertical direction, which provides sufficient space for the interchange of the positions of the clamping member 73 and the suction member 74.

[0099] The rotary drive 71 has two degrees of freedom of movement in the horizontal direction, which provides a basis for moving the vehicle cover into the placement area.

[0100] The support column 75 serves a supporting function. It should be emphasized that the support is the foundation. Even if the support structure is not explicitly stated, it should be known that a support structure needs to be set up.

[0101] The clamping member 73 and the suction member 74 share the rotary drive member 71 and the drive unit 76. The clamping member 73 and the suction member 74 have the same degree of freedom of movement. This arrangement simplifies the structure and saves space.

[0102] See Figure 6 , Figure 7 In this embodiment, the film removal assembly 9 includes a film suction member 91 and a clamping part 92 both disposed on the frame 3; the film suction member 91 is used to promote the movement of a portion of the blue film toward the clamping part 92; the clamping part 92 is used to automatically clamp the blue film and cooperate with the product transfer assembly 8 to remove the blue film on the product.

[0103] Optionally, the suction component 91 may refer to the structure of an existing vacuum cleaner. In general, the suction component 91 includes a suction tube and a fan. The suction component 91 may also include a recycling box, with the fan placed inside the recycling box to provide suction at the opening of the suction tube.

[0104] Optionally, the film removal assembly 9 is disposed between the adhesive application carrier conveyor line 4 and the bending carrier conveyor line 5.

[0105] During the product transfer process, the suction member 91 applies suction to the blue film, causing the blue film to have several raised parts. Then, the clamping part 92 clamps the raised parts. In the subsequent process, the product transfer assembly 8 continues to move the product and the blue film closer to the bending carrier 2, while the blue film is restricted within a certain range. Therefore, the blue film gradually separates from the product.

[0106] The clamping part 92 works with the product transfer component 8 to remove the blue film on the product, preventing the blue film from affecting the subsequent production process. The suction part 91 ensures both the film removal effect and the film removal progress. Compared with the existing automatic blue film removal structure design, the structure is simplified.

[0107] See Figure 6 , Figure 7 In this embodiment, the film suction member 91 has a plurality of film suction ports 911 that can move vertically.

[0108] Optionally, the film suction component 91 includes a vertical drive cylinder, under the action of the vertical drive cylinder, each film suction port 911 can move vertically. This is a conventional setting and will not be described in detail here.

[0109] The suction port 911 of the suction device 91 generates suction to attract the blue film. The suction port 911 can move vertically to adjust the suction effect.

[0110] It should be noted that there is suction at the suction port 911. After the blue film is torn, the suction port 911 rises and the clamping part 92 releases its grip on the blue film, and the suction port 911 sucks the blue film away for collection.

[0111] See Figure 6 , Figure 7 In this embodiment, the clamping part 92 includes a plurality of gripper cylinders 921.

[0112] Optionally, there are four gripper cylinders 921 and four suction ports 911, with the four suction ports 911 corresponding to the four gripper cylinders 921.

[0113] The gripper cylinder 921 is an existing structure, and its specific composition and working principle will not be explained in detail here.

[0114] Here, we will take the gripper cylinder 921 as an example to emphasize some points as follows: Some structures in this application can operate automatically, such as the gripper cylinder 921. The gripper cylinder 921 can be used with existing sensors and controllers to achieve automatic operation. This is a conventional setting and should be known even if it is not explicitly stated.

[0115] Here, we will continue to emphasize some points using the gripper cylinder 921 as an example, as follows: The two structures in this application can be connected directly or indirectly. For example, for four gripper cylinders 921, each gripper cylinder 921 can be connected to the frame 3 individually, or it can be installed on a common mounting plate and connected to the frame 3 by the mounting plate.

[0116] See Figure 8 , Figure 9 In this embodiment, the steel sheet transfer assembly 10 includes a moving mechanism 101 disposed on the frame 3, two variable pitch cylinders 102 mounted on the moving mechanism 101, and two suction cup structures 103 respectively disposed on the two variable pitch cylinders 102; the variable pitch cylinders 102 are driven by the moving mechanism 101 and have two degrees of freedom of movement in the horizontal and vertical directions respectively.

[0117] Optionally, the moving mechanism 101 includes an electric slide and a drive cylinder connected to each other, so that the variable pitch cylinder 102 has two degrees of freedom of movement in the horizontal and vertical directions respectively. Other conventional settings will not be described further here.

[0118] Optionally, the variable pitch cylinder 102 can move freely along the four basic directions: the positive x-axis (or y-axis), the negative x-axis (or y-axis), the positive z-axis, and the negative z-axis.

[0119] The suction cup structure 103 includes two or more suction cups. The suction cup structure 103 is described above and will not be elaborated further here.

[0120] When not in operation, there is a first gap between the two suction cup structures 103 and between the two pressing steel sheets. When in operation, due to the adjustment of the two variable pitch cylinders 102, there is a second gap between the two suction cup structures 103 and between the two pressing steel sheets. The second gap is greater than the first gap. By adjusting the gap, the two pressing steel sheets can press the product simultaneously.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
