Description

Technical Field

[0001] This invention relates to a mounting equipment for electronic products, and more particularly to a splicing and separating component and an automatic flexible adhesive application device. Background Technology

[0002] After the motherboard support metal parts of the monitor are stamped in the stamping plant, they enter the accessory assembly process. This process requires attaching thermal conductive silicone of the appropriate specifications to designated locations on the metal parts. The thermal conductive silicone material is generally composed of multiple adhesive sheets formed by cutting lines. The traditional method is manual, requiring people to manually separate the individual adhesive sheets from the thermal conductive silicone material and manually attach the thermal conductive silicone to the designated locations on the metal parts. This process consumes a lot of manpower and has low efficiency and accuracy.

[0003] To save on factory labor costs and improve operational accuracy, it is necessary to propose an automated adhesive application device that can achieve automated operation, has a simple structure, and efficiently separates and positions adhesive sheets for placement, in order to overcome the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an automatic adhesive application device that enables automated assembly line operation, features a simple structure, and achieves efficient adhesive sheet separation and placement positioning, effectively improving the application efficiency and quality of adhesives on electronic products.

[0005] This invention provides a connection and separation assembly for separating raw materials, the raw materials comprising multiple adhesive sheets formed by cutting lines extending along a first direction and a second direction. The assembly comprises a separation platform and multiple separation structures: the separation platform carries the adhesive sheets transmitted along the first direction and peels a row of adhesive sheets adjacent to the edge of the separation platform along the first direction from the backing paper; the multiple separation structures are arranged along the second direction adjacent to the edge of the separation platform, each separation structure including a first clamping arm and a second clamping arm, the first clamping arm and the second clamping arm being relatively close or relatively far apart to perform clamping and opening operations respectively; wherein, after driving the multiple separation structures close to the edge of the separation platform and performing the clamping operation to clamp the row of adhesive sheets, they move away from the separation platform to separate the row of adhesive sheets from an adjacent row of adhesive sheets; the multiple separation structures are further driven to move away from each other to separate the row of adhesive sheets into multiple independent adhesive sheets, and the first clamping arm has a slot for inserting a picking head to grab the corresponding adhesive sheet.

[0006] In one embodiment, the second direction is perpendicular to the first direction, wherein driving the plurality of separation structures to move away from each other includes: driving adjacent separation structures to move away from each other in the second direction; or driving adjacent separation structures to be staggered and separated from each other in the first direction or the vertical direction.

[0007] In one embodiment, the opening of the cutout groove faces the edge of the separation platform.

[0008] In one embodiment, when the first clamping arm is closed to the second clamping arm, a through groove is formed between the first clamping arm and the second clamping arm.

[0009] In one embodiment, one of the first clamping arm and the second clamping arm is a fixed clamping arm, and the other is a movable clamping arm, the movable clamping arm and the fixed clamping arm being hinged together; the movable clamping arm moves closer to or further away from the fixed clamping arm to perform the clamping operation and the opening operation, respectively.

[0010] In one embodiment, the surfaces of both the first and second clamping arms that are in contact with the adhesive sheet are provided with a textured surface.

[0011] In one embodiment, the separation platform includes: a support platform for carrying the adhesive sheet transferred along the first direction; and a backing paper separation unit, the backing paper separation unit including:

[0012] A first movable clamping structure and a second movable clamping structure are arranged at opposite ends of the support platform, the first movable clamping structure and the second movable clamping structure being used to clamp the opposite ends of the backing paper of the adhesive sheet on the support platform;

[0013] Specifically, the first and second movable clamping structures are controlled to move synchronously to peel off a row of adhesive sheets from the backing paper along the first direction adjacent to the edge of the separation platform.

[0014] In one embodiment, the first movable clamping structure moves downward relative to the support platform to tear one end of the base paper; the second movable clamping structure moves along the first direction and presses against the opposite end of the base paper above the support platform.

[0015] The present invention also provides an automatic adhesive application device, comprising: a splicing and separating component as described above; and an adhesive application unit, the adhesive application unit comprising an operating arm and at least one picking head disposed on the operating arm; wherein, after the operating arm drives at least one picking head to move and insert into the corresponding hollow groove to pick up the corresponding adhesive sheet, the first clamping arm and the second clamping arm move away from each other to release the adhesive sheet; the operating arm continues to drive the picking head and the adhesive sheet it has picked up to move to the target position for application.

[0016] In one embodiment, the material handling head is a vacuum suction head.

[0017] Compared with the prior art, the connection and separation assembly provided by the present invention includes a separation platform and multiple separation structures arranged on the edge of the separation platform. The multiple separation structures are driven to approach the edge of the separation platform and perform a clamping operation to clamp a row of adhesive sheets. Then, they move away from the separation platform to separate the row of adhesive sheets from the adjacent row of adhesive sheets. The multiple separation structures are driven to move away from each other to separate the row of adhesive sheets into multiple independent adhesive sheets. This achieves the goal of first separating a row of adhesive sheets from the adjacent row of adhesive sheets along the pre-cut line on the raw material, and then separating the row of adhesive sheets into multiple independent adhesive sheets, resulting in high separation efficiency.

[0018] In addition, the first clamping arm has a hollowed-out groove for inserting the picking head to grab the corresponding adhesive sheet. During the picking and attaching process, the picking head first arrives at the position to absorb the adhesive sheet, and then the separation structure opens. The adhesive sheet will not be pulled due to the opening of the separation structure during picking, which has the advantages of flat attachment and high precision. Attached Figure Description

[0029] To provide a further understanding of the purpose, structure, features, and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0030] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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. Therefore, they should not be construed as limitations on this invention.

[0031] The purpose of this invention is to provide a splicing and separating component and an automatic adhesive bonding device. The splicing and separating component is used to automatically peel off the backing paper row by row from the raw material of the peeling film and separate it into several adhesive sheets. The other components of the automatic adhesive bonding device are used to realize automatic feeding, automatic peeling of the film, and automatic adsorption and bonding of the adhesive sheets. Thus, the automatic adhesive bonding device can realize automated assembly line operation, with simple structure, efficient adhesive sheet separation and bonding positioning, and can improve the bonding quality of adhesives on electronic products.

[0032] Reference Figures 5 to 8 The connection separation assembly 50 is used to separate raw material 100, the raw material 100 including components along the first direction F1 (refer to...). Figure 2 ) and the second direction F2 (refer to) Figure 2Multiple adhesive sheets 103 are formed by multiple cutting lines extending from the paper. The connection and separation assembly includes a separation platform and multiple separation structures 51: the separation platform is used to carry the adhesive sheets transferred along the first direction F1 and peel off a row of adhesive sheets 104 near the edge of the separation platform along the first direction F1 from the backing paper 101; the multiple separation structures 51 are arranged along the second direction F2 near the edge of the separation platform, each separation structure 51 includes a first clamping arm 511 and a second clamping arm 512, the first clamping arm 511 and the second clamping arm 512 are relatively close to each other. The multiple separation structures 51 are driven to approach the edge of the separation platform and perform clamping and opening operations respectively; after clamping a row of adhesive sheets 104, they are driven to move away from the separation platform so that the row of adhesive sheets 104 is separated from the adjacent row of adhesive sheets 104; the multiple separation structures 51 are driven to move away from each other so that the row of adhesive sheets 104 is separated into multiple independent adhesive sheets 103, and the first clamping arm 511 is provided with a hollow groove 510 for inserting the picking head to grab the corresponding adhesive sheet 103.

[0033] It is understood that the connection and separation component 50 of the present invention drives multiple separation structures 51 to first approach and then move away from the separation platform, so that the multiple separation structures 51 separate the raw material 100 to form a row of adhesive sheets 104; then drives the multiple separation structures 51 to move away from each other to separate the row of adhesive sheets 104 to form multiple independent adhesive sheets 103, thereby realizing the separation of adhesive sheets 104 row by row and separating the row of adhesive sheets 104 into multiple independent adhesive sheets 103. The separation of adhesive sheets 103 is highly efficient and has a high degree of automation.

[0034] Combination Figure 2 and Figure 3 ,by Figure 2 From a drawing perspective, the raw material 100 includes multiple adhesive sheets 103 formed by multiple transverse pre-cut lines (parallel to the first direction F1) and multiple longitudinal pre-cut lines (parallel to the second direction F2). The specific process of driving multiple separation structures 51 to separate the raw material 100 into multiple independent adhesive sheets 103 is as follows.

[0035] First, multiple separation structures 51 are driven to move to the right closer to the separation platform and abut against the edge of the separation platform. Each separation structure 51 is controlled to perform a clamping operation to clamp a longitudinal row of raw material 100 on the separation platform that has peeled off the upper film 102 and the backing paper 101. Second, each separation structure 51 is controlled to move to the left away from the separation platform while clamping the raw material 100, so that the clamped raw material 100 is separated along the longitudinal pre-cut line to form a row of adhesive sheets 104. Then, adjacent separation structures 51 are driven to move away from each other in the longitudinal pre-cut line direction, so that the row of adhesive sheets 104 clamped is pulled apart along the transverse pre-cut line to form a plurality of adhesive sheets 103, wherein the longitudinal pre-cut line is perpendicular to the transverse pre-cut line.

[0036] In this embodiment, the separation structure 51 moves in the directions of the longitudinal pre-cut line and the transverse pre-cut line to simulate the process of a worker separating raw materials into several adhesive sheets 103 along the transverse pre-cut line and the longitudinal pre-cut line, which can achieve efficient separation.

[0037] Furthermore, during the separation process described above, the separation structure 51 can move and abut against a designated position on the separation platform by setting an optical sensor for position detection. When the optical sensor detects that the separation structure 51 has moved to the designated position, the first clamping arm 511 and the second clamping arm 512 of the separation structure 51 can be controlled to perform clamping operations to clamp the raw material 100.

[0038] In addition, in other embodiments of the present invention, the adjacent separation structures 51 can be moved in a staggered manner along the direction of the transverse pre-cut line. That is, one of the adjacent separation structures 51 is moved closer to the separation platform along the direction of the transverse pre-cut line and / or the other of the adjacent separation structures 51 is moved away from the separation platform along the direction of the transverse pre-cut line. Through this staggered movement, a row of adhesive sheets 104 can also be pulled back and forth along the transverse pre-cut line to separate into several adhesive sheets 103.

[0039] In a further preferred embodiment of the invention, the adjacent separation structures 51 can be driven to move in a staggered manner in the vertical direction (the vertical direction is perpendicular to the first direction F1 and the second direction F2) to pull and separate a row of adhesive sheets 104 into several adhesive sheets 103 along the transverse pre-cut line.

[0040] In other words, in this invention, the separation of adjacent separation structures 51 being far apart from each other includes: adjacent separation structures 51 being far apart from each other in the second direction F2; or, adjacent separation structures 51 being staggered and separated from each other in the first direction F1; or, adjacent separation structures 51 being staggered and separated from each other in the vertical direction. All of these methods can enable multiple separation structures 51 to separate a row of adhesive sheets 104 into several independent adhesive sheets 103, and this invention is not limited to these methods.

[0041] Furthermore, the separation structure 51 may be disposed on a moving component, which typically includes a power source and a moving base. The power source provides power to drive the moving base to move the separation structure 51 independently in a first direction and a second direction. Of course, the present invention does not limit the specific structure of the moving component. Any combination of the power source and the moving base that meets the above requirements can be used to drive the separation structure 51 of the present invention.

[0042] Reference Figure 1 and Figure 9In another embodiment of the present invention, the first clamping arm 511 of the separation structure 51 is provided with a hollow groove 510. The separated adhesive sheet 103 is clamped by the first clamping arm 511 and the second clamping arm 512, and the adhesive sheet protrudes from the hollow groove 510. The hollow groove 510 facilitates the adsorption of the adhesive application unit 60 of the subsequent automatic adhesive application device by the adsorption head 61 in the state where the adhesive sheet 103 is clamped by the separation structure 51. After the adsorption is completed, the separation structure 51 is opened again. The adsorption head 61 of the adhesive application unit 60 will not pull the adhesive sheet 103 due to the opening operation of the separation structure 51 during the adsorption process, which has the advantages of flat application and high precision.

[0043] Preferably, the opening of the hollow groove 510 faces the edge of the separation platform, so that the material handling head 61 can be inserted into the hollow groove 510 through the opening.

[0044] In one embodiment, the material-grabbing head 61 is a vacuum suction nozzle or vacuum suction cup-like vacuum suction structure, but it is not limited thereto. In other embodiments of the present invention, the material-grabbing head 61 can also be a gripper structure or other grasping structure.

[0045] Continue to refer to Figure 2 , Figures 5 to 7 When the first clamping arm 511 is closed within the second clamping arm 512, a through groove 513 is formed between the first clamping arm 511 and the second clamping arm 512. In the separation structure 51, one of the first clamping arm 511 and the second clamping arm 512 is a fixed clamping arm, and the other is a movable clamping arm. The movable clamping arm moves closer to or further away from the fixed clamping arm to perform clamping and opening operations, respectively. The movable clamping arm and the fixed clamping arm are hinged together by a hinge shaft 515.

[0046] Specifically, the movable clamping arm (e.g., the first clamping arm 511) is located above the fixed clamping arm (e.g., the second clamping arm 512); when the movable clamping arm (e.g., the first clamping arm 511) is closed above the fixed clamping arm (e.g., the second clamping arm 512), a through groove 513 is formed between the movable clamping arm (e.g., the first clamping arm 511) and the fixed clamping arm (e.g., the second clamping arm 512). The movable clamping arm (e.g., the first clamping arm 511) has a clamping end 5111 and a recessed portion 5112 connected to the clamping end on the side facing the fixed clamping arm (e.g., the second clamping arm 512). The clamping end 5111 is located at the front end of the through groove 513, and the recessed portion 5112 corresponds to the through groove 513. The clamping end 5111 and the recessed portion 5112 form a hook-like structure.

[0047] In one embodiment, the surfaces of the first clamping arm 511 and the second clamping arm 512 that are in contact with the adhesive sheet 103 are both provided with textured surfaces, so that the picking head 61 of the adhesive application unit 60 will not pull the adhesive sheet 103 during the picking process due to the opening operation of the first clamping arm 511 and the second clamping arm 512, and the adhesive sheet 103 can be quickly detached from the first clamping arm 511 and the second clamping arm 512.

[0048] In one embodiment, the separation structure 51 further includes a drive link 53 and a slider. The drive link 53 is hinged to the top of a movable clamping arm (e.g., the first clamping arm 511) via another hinge shaft 531. The slider slides to drive the drive link 53, causing the movable clamping arm (e.g., the first clamping arm 511) to pivot closer to or away from the fixed clamping arm (e.g., the second clamping arm 512) to perform clamping and opening operations, respectively. In this embodiment, the drive link 53 and the slider are powered by a cylinder 54 to drive the movable clamping arm to pivot to perform clamping and opening operations, respectively.

[0049] In addition, the separation structure 51 may be detachably connected to an installation structure. The detachable design allows for quick installation and removal through a snap-fit ​​structure, making the separation structure suitable for silicone of different sizes. This improves the versatility of the separation structure of the attachment device for separating adhesive sheets 103 of different sizes. However, this invention is not limited to this.

[0050] In one embodiment, the separation platform includes: a support platform 33 for carrying the raw material 100 transferred along the first direction F1; and a backing paper separation unit 40 including: a first movable clamping structure 41 and a second movable clamping structure 42 arranged at opposite ends of the support platform 33, the first movable clamping structure 41 and the second movable clamping structure 42 being used to clamp the opposite ends of the backing paper 101 of the adhesive sheet raw material 100 on the support platform; wherein the first movable clamping structure 41 and the second movable clamping structure 42 are controlled to move synchronously to peel a row of adhesive sheets 104 adjacent to the edge of the separation platform along the first direction F1 from the backing paper 101.

[0051] The first movable clamping structure 41 moves downward relative to the support platform 33 to tear one end of the bottom paper 101; the second movable clamping structure 42 moves along the first direction and presses against the opposite end of the bottom paper 101 above the support platform 33.

[0052] A second aspect of the present invention also provides an automatic adhesive application device, comprising the aforementioned connection and separation component 50, and an adhesive application unit 60, comprising an operating arm and at least one material-grabbing head 61 disposed on the operating arm; wherein, the operating arm drives at least one material-grabbing head 61 to move and insert into the hollow groove 510 of the first clamping arm 511 of the corresponding separation component 50 to grasp the corresponding adhesive sheet 103, after which the first clamping arm 511 and the second clamping arm 512 move away from each other, releasing the adhesive sheet 103; the operating arm continues to drive the material-grabbing head 61 and the grasped adhesive sheet 103 to move to the target position for application.

[0053] Specifically, refer to Figure 1 , Figure 2 and Figure 8 The automatic adhesive application device of the present invention includes: an automatic feeding unit, an upper film separation unit 30, a connection separation component 50, and an adhesive application unit 60. The automatic feeding unit includes an automatic feeding module 10 and an automatic picking module 20. The raw material 100 is conveyed by the automatic feeding module 10, and after being adsorbed by the automatic picking module 20, it is transferred to the upper film separation unit 30 to remove the upper film 101 of the raw material 100. The bottom paper separation unit 40 in the connection separation component 50 peels a row of adhesive sheets 104 adjacent to the edge of the support platform 33 along the first direction from the bottom paper 102. The raw material 100 is clamped and separated into multiple independent adhesive sheets 103 by the separation structure 51. Finally, the multiple independent adhesive sheets 103 are vacuum adsorbed and fixed by the adhesive application unit 60 and moved to the target position for automatic application.

[0054] The following is a brief explanation of the functions of each module in the automatic flexible adhesive application device.

[0055] Reference Figures 1 to 3 The automatic feeding module 10 includes a feeding platform 12 and a sensor 11. The feeding platform 12 receives the raw material 100 and transports the raw material 100 to a designated position through lifting and lowering movements. The sensor 11 is set on the top of the support 13 of the automatic feeding module 10 and is used to detect whether the raw material 100 is located at the designated position.

[0056] Specifically, the feeding platform 12 moves upward under the drive of a servo motor until the sensor 11 detects that the raw material 100 has reached the designated height. The feeding platform 12 has several raw materials 100 stacked on it. After the vacuum adsorption head 21 of the automatic material handling module 20 vacuum adsorbs and removes one piece of raw material 100, the sensing signal of the sensor 11 disappears. The controller receives the feedback signal from the sensor 11 and controls the feeding platform 12 to rise to make up for the target height of the raw material 100.

[0057] In this embodiment, an interactive unit is also provided. When all raw materials 100 are exhausted, the controller controls the display interface of the interactive unit to display a raw material shortage prompt. Of course, in other embodiments of the present invention, the controller can also output voice prompts via voice broadcast.

[0058] Reference Figure 2 The automatic material handling module 20 includes a horizontal moving unit and a vertical moving unit. The controller controls the horizontal moving unit and the vertical moving unit to move the vacuum adsorption head 21 to a designated position to vacuum adsorb the raw material 100. The vacuum adsorption head 21 is connected to, for example, a vacuum component 70, which generates a vacuum so that the vacuum adsorption head 21 vacuum adsorbs the raw material 100.

[0059] Reference Figures 1 to 3 The upper film separation unit 30 and the lower paper separation unit 40 are located adjacent to the automatic feeding module 10, so as to... Figure 2 From the perspective of the drawing, the upper film separation unit 30 and the bottom paper separation unit 40 are arranged in approximately parallel directions perpendicular to the paper surface.

[0060] In this embodiment, the carrier platform 33 has a rotation function, so the upper film separation unit 30 and the bottom paper separation unit 40 can share the carrier platform 33. This setting can make the conveying and mounting positioning efficiency of the automatic adhesive application device higher and the adaptability better, which helps to reduce costs and improve work efficiency.

[0061] The automatic material handling module 20 places the raw material 100 at the target position on the carrying platform 33. After the upper film separation unit 30 removes the upper film 102 of the raw material 100, the carrying platform 33 is rotated so that it corresponds to the bottom paper separation unit 40, and the bottom paper 101 of the raw material 100 is removed by the bottom paper separation unit 40.

[0062] The upper film separation unit 30 includes a horizontal peeling unit 31 and a vertical peeling unit 32 arranged at opposite ends of the support platform 33. The horizontal peeling unit 31 clamps the torn end of the upper film 101 of the raw material 100 and moves horizontally to the other end of the upper film 101 of the raw material 100 to tear the upper film. The horizontal peeling unit 31 is released, and the vertical peeling unit 32 clamps the torn end of the upper film 101 and moves downward to completely peel off the upper film 101.

[0063] The bottom paper separation unit 40 includes a first movable clamping structure 41 and a second movable clamping structure 42 arranged at opposite ends of the support platform 33. The first movable clamping structure 41 and the second movable clamping structure 42 are respectively used to clamp the opposite ends of the bottom paper 102 on the raw material 100. The controller controls the first movable clamping structure 41 and the second clamping structure 42 to move synchronously so that the bottom paper 101 of the raw material 100 is pulled off.

[0064] Specifically, the first movable clamping structure 41 is located on the side of the support platform 33 closer to the separating structure 51, and the second movable clamping structure 42 is located on the side of the support platform 33 farther from the separating structure 51. The first movable clamping structure 41 moves downwards below the support platform 33 and tears one end of the base paper 101, while the second movable clamping structure 42 presses the opposite end of the base paper 101 above the support platform 33. In other words, during the peeling process of the base paper 101 of the raw material 100, there is a height difference between the first movable clamping structure 41 and the second movable clamping structure 42. The second movable clamping structure 42 moves above the support platform 33 and tensions one end of the base paper 101, while the first movable clamping structure 41, located below the support platform 33, tears the other end of the tensioned base paper 101 to effectively peel off the base paper 101.

[0065] by Figure 2 The perspective of the drawing, combined with Figure 3 and Figure 6 After the upper film 101 is peeled off, the carrier platform 33 rotates 180 degrees counterclockwise. The first movable clamping structure 41 on the left clamps the blank position on the left side of the base paper 101, and the second movable clamping structure 42 on the right clamps the blank position on the right side of the base paper 101. The first movable clamping structure 41 is driven to move downward below the carrier platform 33 and tear off one end of the base paper 101, while the second movable clamping structure 42 presses against the opposite end of the base paper 101 above the carrier platform 33 and moves along the first direction, so that the base paper 101 is torn off downward on the side of the carrier platform 33 closest to the separation structure 51, thus completing the separation of the base paper 101 of the raw material 100.

[0066] Understandably, when the peeling of the backing paper 101 causes a longitudinal row of adhesive sheets 104 to appear on the raw material 100, the drive separation structure 51 first approaches and then moves away from the separation platform to remove the longitudinal row of adhesive sheets 104 from the raw material 100 row by row.

[0067] Continue to refer to Figure 2 and Figure 3 The second movable clamping structure 42 includes a cylinder 421. The cylinder 421 drives the front-end gripper to clamp the right side of the bottom paper 101. The cylinder 421 is slidably connected to a slide rail 422. The cylinder 421 slides on the slide rail 422 to realize that the gripper moves along the first direction while clamping and pressing the right side of the bottom paper 101 against the separation platform.

[0068] Reference Figure 2 , Figure 4 , Figure 7 and Figure 8The adhesive application unit 60 includes an operating arm and multiple picking heads 61 disposed at the end of the operating arm; wherein, after the operating arm drives the multiple picking heads 61 to move and respectively pick up multiple adhesive sheets 103, the multiple separation structures 51 respectively perform an opening operation to release the multiple adhesive sheets 103; the operating arm continues to drive the multiple picking heads 61 and the multiple adhesive sheets 103 they have picked up to move to the target position for application.

[0069] The material handling head 61 is, for example, a vacuum suction head, including a suction nozzle 62 and a vacuum channel 63 connected to the suction nozzle 62. The vacuum channel 63 is connected to the vacuum assembly 70 so that the suction nozzle 62 generates a vacuum suction force.

[0070] In actual use, the operating arm, for example, is a multi-degree-of-freedom industrial robotic arm. The suction nozzle 62 first picks up the adhesive sheet 103 held by the closing operation of the separation structure at the target position. After vacuum adsorption is completed, each movable clamping arm (e.g., the first clamping arm 511) in the multiple separation structures 51 is controlled to lift relative to the corresponding fixed clamping arm (e.g., the second clamping arm 512) to perform an opening operation. The operating arm controls the suction nozzle 62 to move and complete the material picking, preventing the adhesive sheet 103 from being pulled when the movable clamping arm (e.g., the first clamping arm 511) lifts and opens during material picking. In addition, after the adhesive sheet 103 is picked up, it moves to the designated position under the support of the industrial robotic arm for automatic adhesion of the adhesive sheet 103.

[0071] In summary, the connection separation component and automatic adhesive application device provided by this invention include a separation platform and multiple separation structures arranged along the edge of the separation platform. The multiple separation structures are driven to approach the edge of the separation platform and perform a clamping operation to hold a row of adhesive sheets. Then, they move away from the separation platform to separate the row of adhesive sheets from an adjacent row. The multiple separation structures are then driven further away from each other to separate the row of adhesive sheets into multiple independent adhesive sheets. This achieves high adhesive sheet separation efficiency by first separating a row of adhesive sheets from an adjacent row along a pre-cut line on the raw material, and then separating the row of adhesive sheets into multiple independent adhesive sheets. Furthermore, the first clamping arm has a hollowed-out groove for inserting a picking head to grab the corresponding adhesive sheet. During the picking and application process, the picking head first arrives at its position to absorb the adhesive sheet, and then the separation structure opens. This prevents the adhesive sheet from being pulled during the picking process, resulting in smooth application and high precision.

[0072] In addition, the feeding unit, film separation unit and backing paper separation unit of the automatic adhesive bonding device can further automate all the preceding operations from feeding to film peeling and separation, ensuring automated bonding, significantly saving the factory's labor costs and improving operational accuracy.
