Description

Technical Field

[0001] This invention relates to the field of patch technology, and more specifically, to a system for applying adhesive to flat castings. Background Technology

[0002] In some processing scenarios, it is necessary to apply a flexible film to the surface of plate-shaped parts, such as flat panels. This film has a certain degree of deformation capability, allowing it to be folded and wrapped around the two opposing surfaces of the flat panel. That is, the film is first applied to one surface of the flat panel, then folded to wrap around one side of the flat panel, and finally applied to the other surface. In existing technology, to achieve the bonding of the film to the two surfaces of the flat panel, a manual step-by-step operation is performed: first, the film is applied to one surface, then folded to wrap around the side of the flat panel before being applied to the other surface.

[0003] The inventors discovered that the process of bonding films to flat parts using related technologies has at least the following drawbacks:

[0004] Manual operation is inefficient, and the quality of the surface mount technology (SMT) is greatly affected by the operator's skill level, resulting in inconsistent SMT quality and making it difficult to guarantee the yield rate of the products. Summary of the Invention

[0005] The present invention aims to provide a system for applying adhesive to flat castings, which can achieve semi-automatic application, reduce manual intervention, lower the difficulty of operation, improve operational efficiency, reduce errors, and improve the quality of application.

[0006] The embodiments of the present invention can be implemented as follows:

[0007] In a first aspect, the present invention provides an adhesive application system for flat castings, comprising:

[0008] A first adhesive applicator and a second adhesive applicator. The first adhesive applicator includes a first worktable, a first sliding member, and a first adhesive applicator mechanism. The first sliding member is slidably engaged with the first worktable in a first direction and is used to support a workpiece. The first adhesive applicator mechanism is mounted on the first worktable and is used to position the adhesive film and press one side of the adhesive film onto the workpiece. The first sliding member is used to drive the workpiece to move along the first direction to cooperate with the first adhesive applicator mechanism to adhere the adhesive film to the first surface of the workpiece to form a semi-finished product.

[0009] The second adhesive applicator includes a second worktable, a second sliding member, and a second adhesive applicator mechanism; the second sliding member is slidably engaged with the second worktable in a first direction, and the second sliding member is used to carry the semi-finished product; the second adhesive applicator mechanism is used to apply the adhesive sheet protruding from the side of the workpiece on the semi-finished product to the second surface of the workpiece; the first surface and the second surface are arranged opposite to each other.

[0010] In an optional embodiment, the first adhesive applicator includes a positioning carrier and a first flattening component. The positioning carrier is mounted on the first worktable and is used to carry the adhesive sheet. The first flattening component and the first worktable are slidably engaged in a second direction that forms an angle with the first direction. The first flattening component and the positioning carrier cooperate to clamp the adhesive sheet. When one side of the adhesive sheet is attached to the workpiece, under the action of the first sliding component, the adhesive sheet can be detached from the positioning carrier and the first flattening component and attached to the first surface.

[0011] Based on the above solution, the film to be applied is placed on the positioning carrier, which supports the film and initially positions it. Then, the first flattening component is lowered to press the film onto the positioning carrier. This not only achieves flatness of the film but also ensures the stability of its position by clamping it with the positioning carrier and the first flattening component. This prevents the film from shifting during the application process, improves the accuracy of the film's position relative to the positioning carrier, and enhances the application quality.

[0012] In an optional embodiment, the first adhesive applicator further includes a clamping member that is slidably engaged with the first worktable in a second direction. The clamping member is located in front of the positioning carrier in the first direction and is used to press one side of the patch against the first surface.

[0013] Based on the above scheme, after the film is clamped by the positioning carrier and the first flat member, the clamping member descends to press part of the film onto the workpiece on the first sliding member. At this time, the first sliding member continues to move along the first direction, and the film can move with the workpiece. The film gradually detaches from the positioning carrier and gradually adheres to the first surface of the workpiece. The clamping member not only achieves the initial adhesion between the film and the workpiece, allowing the first sliding member to move the workpiece along the first direction while simultaneously moving the film, but also ensures that the distance between the clamping member and the first surface of the workpiece is perfectly matched to the thickness of the film. As the first sliding member moves the workpiece, the film can be tightly adhered to the first surface under the action of the clamping member, realizing automatic film application.

[0014] In an optional embodiment, the clamping member includes a connecting rod and a clamping roller, the connecting rod being slidably engaged with the first worktable in a second direction, and the clamping roller being rotatably mounted on the connecting rod for attaching a portion of the patch to the first surface.

[0015] Based on the above scheme, the pressing roller presses the film onto the first surface of the workpiece. As the first sliding component drives the workpiece to move in the first direction, the film gradually adheres to the first surface. The friction between the film and the pressing roller causes the pressing roller to rotate. That is, there is rolling friction between the film and the pressing roller. The friction is small and much smaller than the static friction between the film and the first surface, so it is not easy for the film and the workpiece to have relative displacement.

[0016] In an optional embodiment, the positioning carrier includes a frame and multiple rotating rollers, all of which are rotatably disposed on the frame. The multiple rotating rollers cooperate to define a bearing plane for carrying the patch. The bearing plane has an angle with a first direction, and the lower side of the bearing plane is located in front of the higher side of the bearing plane in the first direction.

[0017] Based on the above scheme, multiple rotating rollers can rotate when the film leaves the area between the positioning carrier and the first flattening part, reducing the friction between the film and the rotating rollers. When the workpiece drives the film to move, the film is less likely to be relatively displaced from the workpiece due to the clamping force of the positioning carrier and the first flattening part, resulting in high patching quality.

[0018] In an optional embodiment, the first sliding member is provided with a first limiting platform, which is used to abut against one side of the patch located on the positioning carrier to position the initial position of the film and the workpiece.

[0019] Based on the above scheme, the workpiece is placed on the first sliding member and positioned by the first sliding member. When the first sliding member slides towards the first adhesive applicator and is in the set position, the adhesive film is placed on the positioning carrier, and one side of the adhesive film abuts against the first limiting stage. In this way, the initial positions of the adhesive film and the workpiece are achieved, eliminating the need for further position calibration of the workpiece and the adhesive film. The adhesive film is directly pressed onto the first surface of the workpiece by the clamping member, which is convenient and efficient.

[0020] In an optional embodiment, the second adhesive applicator includes a second flattening component, a pushing component, and a third flattening component; the second flattening component is slidably engaged with the second worktable in a second direction, and the second flattening component is used to clamp the semi-finished product in cooperation with the second sliding component; the pushing component is movably engaged with the second worktable, and the pushing component is used to move in the second direction to fold the adhesive sheet protruding from the side of the workpiece, and then move in the third direction to apply the folded adhesive sheet to the second surface; the third flattening component is slidably engaged with the second worktable in the second direction, and is used to contact the adhesive and press the adhesive sheet firmly onto the second surface;

[0021] The third direction has an angle with both the first and second directions, and the fourth direction is opposite to the second direction.

[0022] Based on the above scheme, after the film is applied for the first time by the first adhesive applicator, the film is affixed to the first surface of the workpiece, with one side of the film protruding from the corresponding side of the workpiece. The semi-finished product, consisting of the film and the workpiece, is placed on the second sliding member, which is used for positioning and transportation. For example, when the semi-finished product is placed on the second sliding member, the film is above the workpiece, meaning the workpiece contacts the second sliding member, and the workpiece is positioned by the second sliding member. Due to the high strength of the workpiece, it is not easily deformed, resulting in good positioning. At the same time, part of the second surface of the workpiece is not blocked by the second sliding member, making it easier to fold and attach the protruding part of the film to the second surface later. After the second sliding member transports the semi-finished product to the set position along the second direction, the film is below the pusher and the third flattener is below the workpiece. The second flattener is activated, causing it to descend and press onto the semi-finished product. In this way, the second sliding member and the second flattener work together to further define the position of the semi-finished product. Then, the pusher moves along the second direction, contacts the protruding part of the film, and drives the film to fold towards the second surface of the workpiece. When the film is blocked, the pusher moves along the third direction again, causing the film to fold again and adhere to the second surface. Then, the pusher resets, and the third flattening member rises along the fourth direction, further pressing the film onto the second surface, thus achieving the adhesion of the film and the workpiece.

[0023] In an optional embodiment, the pusher includes a telescopic rod and a pusher roller. The telescopic rod is slidably engaged with the second worktable in a third direction, and the pusher roller is connected to the telescopic rod. The telescopic rod is used to drive the pusher roller to move in a second direction.

[0024] Based on the above solution, when the push roller drives the film to fold onto the workpiece, the push roller itself can rotate, resulting in low friction between it and the film, making it less likely to damage the film.

[0025] In an optional embodiment, the second sliding member is provided with a second limiting platform, which is used to abut against the workpiece to limit the initial position of the workpiece on the second sliding member.

[0026] Based on the above scheme, by setting a second limiting stage, the workpiece can be positioned on the second sliding member, and the probability of the workpiece moving relative to the second sliding member is reduced. During the placement process, the film and the workpiece are not easily displaced, resulting in high placement quality.

[0027] In an optional embodiment, the first worktable is provided with a first slide rail, and the first sliding member is slidably engaged with the first slide rail in a first direction; or, the second worktable is provided with a second slide rail, and the second sliding member is slidably engaged with the second slide rail in a first direction.

[0028] Based on the above scheme, the sliding of the first sliding member and the second sliding member is stable and reliable.

[0029] The beneficial effects of the adhesive application system for flat castings provided in this embodiment of the invention include:

[0030] In summary, the adhesive application system for flat castings provided in this embodiment, through the cooperation of a first adhesive application device and a second adhesive application device, can complete the application of adhesive film to the opposing first and second surfaces of the workpiece in steps. Compared with the prior art, which relies entirely on manual application, this system boasts a high degree of automation, low labor intensity, and high efficiency. Furthermore, it minimizes human intervention, reduces the impact of worker experience on the application quality, and results in high-quality application. In actual operation, the first adhesive application device adheres the adhesive film to the first surface of the workpiece. Then, the semi-finished product, after the first application, can be picked up manually or by a robotic arm, transported and positioned on the second sliding component, and the second adhesive application mechanism completes the application of the adhesive film to the second surface of the workpiece. This results in a tight fit, low application difficulty, and high application efficiency. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0042] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0043] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0044] In the existing technology, when bonding film 002 to the surface of flat parts, it is basically done manually, which is labor-intensive, inefficient, and the different experience of workers has a great impact on the bonding quality, resulting in large product differences and low yield.

[0045] In view of this, the designers have provided a glue application system for flat castings, which is highly automated, efficient and of high quality compared to the existing manual application technology.

[0046] Please combine Figure 1 In this embodiment, it should be noted that the adhesive application system is mainly suitable for attaching a rectangular film 002 to a rectangular flat part. The flat part has four sides and opposing first and second surfaces. The four sides are connected end-to-end, and the first and second surfaces are positioned opposite each other. The distance between the first and second surfaces is the thickness of the flat part. After the film 002 is first attached to the workpiece 001, three edges of the film 002 are aligned with three of the four sides of the workpiece 001, and the fourth edge of the film 002 protrudes from the fourth side of the workpiece 001. After the second attachment, the portion of the film 002 near the fourth side is folded twice and then attached to the second surface of the workpiece 001.

[0047] Please combine Figures 2-4In this embodiment, the adhesive application system for flat castings includes a first adhesive application device 100 and a second adhesive application device 200. The first adhesive application device 100 includes a first worktable 110, a first sliding member 120, and a first adhesive application mechanism 130. The first sliding member 120 is slidably engaged with the first worktable 110 in a first direction 003, and is used to support the workpiece 001. The first adhesive application mechanism 130 is mounted on the first worktable 110 and is used to position the adhesive sheet 002 and press one side of the adhesive sheet 002 onto the workpiece 001. The first sliding member 120 is used to drive the workpiece 001 to move along the first direction 003, so as to cooperate with the first adhesive application mechanism 130 to adhere the adhesive sheet 002 to the first surface of the workpiece 001 to form a semi-finished product. The second adhesive applicator 200 includes a second worktable 210, a second sliding member 220, and a second adhesive applicator mechanism; the second sliding member 220 is slidably engaged with the second worktable 210 in a first direction 003, and the second sliding member 220 is used to carry the semi-finished product; the second adhesive applicator mechanism is used to attach the adhesive sheet 002 protruding from the side of the workpiece 001 on the semi-finished product to the second surface of the workpiece 001; the first surface and the second surface are arranged opposite to each other.

[0048] As described above, the working method of the adhesive application system for flat castings provided in this embodiment includes, for example:

[0049] During operation, workpiece 001 is first placed on the first sliding member 120. The first sliding member 120 slides along the first direction 003 to the first station, at which point workpiece 001 is located below the first adhesive applicator. Then, adhesive film 002 is placed on the first adhesive applicator 130, which uses the first adhesive applicator 130 to adhere adhesive film 002 to the first surface of workpiece 001. Subsequently, the semi-finished product after the first adhesion can be removed from the first sliding member 120 manually or by a robot, and positioned on the second sliding member 220. The second sliding member 220 slides along the first direction 003 to the second station, corresponding to the position of the second adhesive applicator 230. The second adhesive applicator 230 then completes the adhesion of adhesive film 002 to the second surface of workpiece 001. In this way, by cooperating with the first adhesive applicator 100 and the second adhesive applicator 200, the adhesive film 002 can be applied to the first and second surfaces of the workpiece 001 in steps. Compared with the existing technology that relies entirely on manual application, this method has a high degree of automation, low labor intensity, high efficiency, less human intervention, and less impact of worker experience on the application quality, resulting in high application quality.

[0050] It should be understood that when the first sliding member 120 moves the workpiece 001 to the first station, it can also move to the station in the opposite direction to the first direction 003. The adjustment can be made according to the initial relative position of the first sliding member 120 and the first station. Similarly, when the second sliding member 220 moves the semi-finished product to the second station, it can also move to the station in the opposite direction to the first direction 003. The adjustment can be made according to the initial relative position of the second sliding member 220 and the second station.

[0051] The following embodiments illustrate the detailed structure of the adhesive application system for flat castings provided in this application.

[0052] In this embodiment, optionally, the first adhesive applicator 130 includes a positioning carrier 131 and a first flattening member 132. The positioning carrier 131 is mounted on the first worktable 110 and is used to carry the adhesive sheet 002. The first flattening member 132 and the first worktable 110 are slidably engaged in a second direction 004 that forms an angle with the first direction 003. The first flattening member 132 and the positioning carrier 131 cooperate to clamp the adhesive sheet. When one side of the adhesive sheet is attached to the workpiece 001, under the action of the first sliding member 120, the adhesive sheet can be detached from between the positioning carrier 131 and the first flattening member 132 and attached to the first surface.

[0053] It should be understood that when the film 002 to be applied is placed on the positioning carrier 131, the positioning carrier 131 carries the film 002 and initially positions the film 002. Then, the first flattening component 132 is lowered to press the film 002 onto the positioning carrier 131. This not only achieves the flatness of the film 002, but also ensures the stability of the position of the film 002 by clamping the film 002 with the cooperation of the positioning carrier 131 and the first flattening component 132. This makes it less likely for the film 002 to shift during the application process, improves the accuracy of the position of the film 002 relative to the positioning carrier 131, and improves the application quality.

[0054] In this embodiment, optionally, the first adhesive applicator 130 further includes a pressing member 133, which is slidably engaged with the first worktable 110 in the second direction 004. The pressing member 133 is located in front of the positioning carrier 131 in the first direction 003, and is used to press one side of the patch onto the first surface.

[0055] During operation, the film 002 is clamped by the positioning carrier 131 and the first flattening member 132. Then, the clamping member 133 descends to press part of the film 002 onto the workpiece 001 on the first sliding member 120. At this time, the first sliding member 120 continues to move along the first direction 003, allowing the film 002 to move together with the workpiece 001. The film 002 gradually detaches from the positioning carrier 131 and gradually adheres to the first surface of the workpiece 001. The clamping member 133 not only achieves initial adhesion between the film 002 and the workpiece 001, allowing the first sliding member 120 to move the workpiece 001 along the first direction 003 while simultaneously moving the film 002, but also ensures that the distance between the clamping member 133 and the first surface of the workpiece 001 is perfectly matched to the thickness of the film 002. As the first sliding member 120 moves the workpiece 001, the film 002 is tightly adhered to the first surface under the action of the clamping member 133, achieving automatic film application.

[0056] In an optional embodiment, the pressing member 133 includes a connecting rod 1331 and a pressing roller 1332. The connecting rod 1331 is slidably engaged with the first worktable 110 in the second direction 004. The pressing roller 1332 is rotatably mounted on the connecting rod 1331 and is used to adhere a portion of the patch to the first surface. The pressing roller 1332 presses the film 002 onto the first surface of the workpiece 001. As the first sliding member 120 moves the workpiece 001 along the first direction 003, the film 002 gradually adheres to the first surface. The friction between the film 002 and the pressing roller 1332 causes the pressing roller 1332 to rotate. That is, there is rolling friction between the film 002 and the pressing roller 1332. The friction is small and much smaller than the static friction between the film 002 and the first surface, making it less likely that the film 002 and the workpiece 001 will have relative displacement.

[0057] Optionally, the positioning carrier 131 includes a frame 1311 and multiple rotating rollers 1312. The multiple rotating rollers 1312 are rotatably mounted on the frame 1311, and cooperate to define a bearing plane for carrying the patch. The bearing plane forms an angle with a first direction 003, and the lower side of the bearing plane is located in front of the higher side of the bearing plane in the first direction 003. For example, in this embodiment, the frame 1311 is a rectangular frame, and the number of rotating rollers 1312 is four, evenly spaced.

[0058] In actual operation, multiple rotating rollers 1312 can rotate when the film 002 leaves the area between the positioning carrier 131 and the first flattening component 132, reducing the friction between the film 002 and the rotating rollers 1312. When the workpiece 001 drives the film 002 to move, the film 002 is less likely to be relatively displaced from the workpiece 001 due to the clamping force of the positioning carrier 131 and the first flattening component 132, resulting in high patching quality.

[0059] It should be understood that, with the top surface of the first working platform as the reference surface, the top surface of the first working platform is a plane and parallel to the horizontal plane. The bearing plane formed by the cooperation of multiple rotating rollers 1312 has an acute angle with the horizontal plane, which can be 40-50°.

[0060] In this embodiment, optionally, a first limiting stage 140 is provided on the first sliding member 120. The first limiting stage 140 is used to abut against one side of the patch located on the positioning carrier 131 to position the patch and the workpiece 001 at their initial positions. When the workpiece 001 is placed on the first sliding member 120, it is positioned by the first sliding member 120. When the first sliding member 120 slides toward the first adhesive applicator and is in the set position, the adhesive film 002 is placed on the positioning carrier 131, and one side of the adhesive film 002 abuts against the first limiting stage 140. In this way, the initial positions of the adhesive film 002 and the workpiece 001 are positioned, and there is no need to perform position calibration of the workpiece 001 and the adhesive film 002. The clamping member 133 directly presses part of the adhesive film 002 onto the first surface of the workpiece 001, which is convenient and efficient.

[0061] Furthermore, when the first flattening member 132 presses the film 002 located on the positioning carrier 131, the pressing member 133 can move synchronously with the first flattening member 132, and both of them contact the film 002 simultaneously. Alternatively, the pressing member 133 contacts the film 002 after the first flattening member 132, that is, the first flattening member 132 first flattens the film 002, and then the pressing member 133 presses part of the film 002 onto the first surface of the workpiece 001, thereby improving the bonding quality.

[0062] In this embodiment, optionally, the second adhesive applicator 230 includes a second flattening member 231, a pushing member 232, and a third flattening member 233; the second flattening member 231 is slidably engaged with the second worktable 210 in the second direction 004, and the second flattening member 231 is used to clamp the semi-finished product in cooperation with the second sliding member 220; the pushing member 232 is movably engaged with the second worktable 210, and the pushing member 232 is used to move along the second direction 004 to fold the adhesive sheet 002 protruding from the side of the workpiece 001, and then move along the third direction 005 to adhere the folded adhesive sheet 002 to the second surface; the third flattening member 233 is slidably engaged with the second worktable 210 in the second direction 004, and is used to contact the adhesive and press the adhesive firmly onto the second surface; the third direction 005 has an angle with both the first direction 003 and the second direction 004, and the fourth direction 006 is opposite to the second direction 004. For example, in this embodiment, the first direction 003, the second direction 004, and the third direction 005 are perpendicular to each other.

[0063] It should be understood that after the first adhesive application mechanism completes the first application of the film 002, the film 002 is affixed to the first surface of the workpiece 001, with one side of the film 002 protruding from the corresponding side of the workpiece 001. The semi-finished product, consisting of the film 002 and the workpiece 001, is placed on the second sliding member 220 for positioning and transport. For example, when the semi-finished product is placed on the second sliding member 220, the film 002 is located above the workpiece 001, meaning the workpiece 001 is in contact with the second sliding member 220. The workpiece 001 is positioned by the second sliding member 220. Due to the high strength and resistance to deformation of the workpiece 001, the positioning effect is good. Simultaneously, a portion of the second surface of the workpiece 001 is not obstructed by the second sliding member 220, facilitating the subsequent folding and bonding of the protruding portion of the film 002 to the second surface. After the second sliding member 220 conveys the semi-finished product to the set position along the second direction 004, the film 002 is located below the pusher 232, and the third flattening member 233 is located below the workpiece 001. The second flattening member 231 is activated, causing it to descend and press onto the semi-finished product. In this way, the second sliding member 220 and the second flattening member 231 cooperate to further define the position of the semi-finished product. Then, the pusher 232 moves along the second direction 004, contacting the protruding part of the film 002 and causing the film 002 to fold towards the second surface of the workpiece 001. When the film 002 is blocked, the pusher 232 moves along the third direction 005, causing the film 002 to fold again and adhere to the second surface. Then, the pusher 232 resets, and the third flattening member 233 rises along the fourth direction 006, further pressing the film 002 onto the second surface, thus achieving the adhesion of the film 002 and the workpiece 001.

[0064] In this embodiment, optionally, the second flattening component 231 includes a telescopic rod 2321 and a pusher roller 2322. The telescopic rod 2321 is slidably engaged with the second worktable 210 in a third direction 005. The pusher roller 2322 is connected to the telescopic rod 2321, and the telescopic rod 2321 is used to drive the pusher roller 2322 to move in the second direction 004. When the pusher roller 2322 drives the film 002 to fold onto the workpiece 001, the pusher roller 2322 itself can rotate, resulting in low friction between it and the film 002, making it less likely to damage the film 002.

[0065] In this embodiment, optionally, a second limiting stage 240 is provided on the second sliding member 220. The second limiting stage 240 is used to abut against the workpiece 001 to limit the initial position of the workpiece 001 on the second sliding member 220. By providing the second limiting stage 240, the workpiece 001 can be positioned on the second sliding member 220, and the probability of the workpiece 001 moving relative to the second sliding member 220 is reduced. During the bonding process, the film 002 and the workpiece 001 are less likely to shift, resulting in high bonding quality.

[0066] In this embodiment, optionally, a first slide rail 150 is provided on the first worktable 110, and the first sliding member 120 is slidably engaged with the first slide rail 150 in the first direction 003; or, a second slide rail 250 is provided on the second worktable 210, and the second sliding member 220 is slidably engaged with the second slide rail 250 in the first direction 003. The sliding of the first sliding member 120 and the second sliding member 220 is stable and reliable.

[0067] It should be understood that the sliding components such as the first sliding component 120, the second sliding component 220, the first leveling component 132, the pressing component 133, the second leveling component 231, the pushing component 232, and the third leveling component 233 can all be driven by telescopic mechanisms such as cylinders, hydraulic cylinders, or electric push rods to perform linear reciprocating motion.

[0068] The adhesive application system for flat castings provided in this embodiment, through the cooperation of the first adhesive application device 100 and the second adhesive application device 200, can complete the application of the adhesive film 002 to the opposite first and second surfaces of the workpiece 001 in steps. Compared with the prior art which relies entirely on manual application, it has a high degree of automation, low labor intensity, high efficiency, less human intervention, and less impact of worker experience on the application quality, resulting in high application quality.

[0069] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
