Description

[0002] Display screen film replacement and bonding equipment is widely used in the display industry, electronics industry, automotive industry, etc. It is used to bond a support film to the surface of the display screen. However, the bonding effect is often poor, resulting in a low yield of finished products.

[0003] The related technology provides a bonding device including a film bonding module and a screen bonding module. The film bonding module carries the film to be bonded, and the screen bonding module carries the screen to be bonded and drives the screen to be bonded to flip and adhere tightly to the film. Then the film bonding module and the screen bonding module move away from each other, so that the film to be bonded is bonded to the screen to be bonded. However, during the long-term bonding process, since the cables of various components on the screen bonding module all pass through the holes on the side of the screen bonding module, the repeated flipping of the screen bonding module causes friction between the cables and between the cables and the inner wall of the holes, resulting in damage to the cable sheaths. This affects the control signals of some components, causing the bonding process to be interrupted or the bonding process to be disordered.

[0004] Therefore, there is an urgent need for an automatic bonding device to solve the above problems. Utility Model Content

[0031] This utility model discloses an automatic bonding device. The screen to be bonded is fixed to a screen support structure with the bonding surface facing upwards. The film to be bonded is placed at the output end of the film bonding unit, with the bonding surface facing upwards. Then, the screen flipping structure rotates so that the bonding surface of the screen to be bonded faces downwards, causing the cable protection unit, located in the middle of the support frame and connected between the screen flipping structure and the support frame, to flip synchronously. A horizontal moving unit is activated, driving the film bonding unit and the screen support structure closer together until the screen and the film to be bonded are aligned. At this point, the film bonding unit is not in contact with the cable protection unit. Then, the film bonding unit drives the film to be bonded upwards and into contact with the screen. Afterwards, the horizontal moving unit is activated, causing the film bonding unit and the screen support structure to move away from each other. During this movement, the film to be bonded is pressed firmly onto the screen, completing the bonding process. With the above settings, during the bonding process between the film to be bonded and the screen to be bonded, the cable protection unit located in the middle of the support frame flips with the rotation of the screen flipping structure, avoiding interference between the cable and other structures that would cause wear on the cable sheath. It also avoids mutual squeezing and friction between the cables due to the small space for cable arrangement, reducing the probability of cable failure, ensuring the stability of cable signal transmission, and ensuring the stability and reliability of the bonding between the film to be bonded and the screen to be bonded. At the same time, it reduces the frequency of maintenance and extends the service life of the automatic bonding device.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0047] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] This embodiment provides an automatic bonding device, such as... Figures 1-4 As shown, the automatic bonding device includes a film bonding unit 1, a screen bonding unit 2, a cable protection unit 3, and a horizontal movement unit 4. Two film bonding units 1 are provided, spaced apart. The output end of each film bonding unit 1 is used to hold the film to be bonded. Each film bonding unit 1 can drive the film to be bonded to rise or fall. The screen bonding unit 2 includes a support frame 21, a screen flipping structure 23, and two screen carrying structures 22. The screen flipping structure 23 is rotatably connected to the support frame 21. The two screen carrying structures 22 are spaced apart and connected to the screen flipping structure 23. The screen carrying structures 22 are used for... With the screen to be bonded fixed, the screen flipping structure 23 is configured to drive the screen carrier structure 22 to flip so that the screen to be bonded and the film to be bonded are aligned. One end of the cable protection unit 3 is connected to the support frame 21, and the other end of the cable protection unit 3 is connected to the screen flipping structure 23. The cable protection unit 3 contains a cable and is located in the middle of the support frame 21 along the direction from one screen carrier structure 22 to the other. The film bonding unit 1 is connected to the output end of the horizontal moving unit 4 so as to drive the film bonding unit 1 to move closer to or away from the screen carrier structure 22.

[0050] By fixing the screen to be bonded to the screen support structure 22 with the bonding surface facing upwards, the film to be bonded is placed at the output end of the film bonding unit 1 with the bonding surface facing upwards. Then, the screen flipping structure 23 rotates so that the bonding surface of the screen to be bonded faces downwards, so that the cable protection unit 3, which is located in the middle of the support frame 21 and connects the screen flipping structure 23 and the support frame 21, flips synchronously. Then, the horizontal moving unit 4 is activated and drives the film bonding unit 1 and the screen support structure 22 to move closer to each other until the screen to be bonded and the film to be bonded are aligned. At this time, the film bonding unit 1 is not in contact with the cable protection unit 3. Then, the film bonding unit 1 drives the film to be bonded to rise and contact the screen to be bonded. Then, the horizontal moving unit 4 is activated and drives the film bonding unit 1 and the screen support structure 22 to move away from each other. During the moving away process, the film to be bonded is pressed onto the screen to be bonded, completing the bonding work. With the above settings, during the bonding process between the film to be bonded and the screen to be bonded, the cable protection unit 3 located in the middle of the support frame 21 rotates with the screen flipping structure 23, which avoids interference between the cable and other structures, thus preventing wear on the cable sheath. It also avoids mutual squeezing and friction between the cables due to the small space for cable arrangement, reducing the probability of cable failure, ensuring the stability of cable signal transmission, and ensuring the stability and reliability of bonding between the film to be bonded and the screen to be bonded. At the same time, it reduces the frequency of maintenance and extends the service life of the automatic bonding device.

[0051] Specifically, in this embodiment, the film to be laminated is a support film. In other embodiments, the film to be laminated is a reinforcing film or an anti-reflective film, etc. No limitations are imposed here.

[0052] Specifically, in this embodiment, the screen flipping structure 23 drives the screen supporting structure 22 to flip 180 degrees. In other embodiments, the screen flipping structure 23 drives the screen supporting structure 22 to flip 150 degrees or 120 degrees, etc. No limitation is made here.

[0053] Specifically, such as Figure 1 As shown, in this embodiment, the horizontal moving unit 4 is a rodless electric cylinder, and the membrane bonding unit 1 is fixedly connected to the slider of the rodless electric cylinder. In other embodiments, the horizontal moving unit 4 is a combination of a motor and a lead screw slide, or a magnetic levitation conveyor line, etc. No limitations are imposed here. Specifically, in this embodiment, the membrane bonding unit 1 is an existing structure, which will not be described in detail here.

[0054] Specifically, in this embodiment, the film bonding unit 1 is an existing structure used in the bonding operation of the screen to be bonded and the film to be bonded. Further details will not be provided here.

[0055] Correspondingly, the screen flip structure 23 and the screen support structure 22 are also existing structures used in the bonding operation of the screen to be bonded and the film to be bonded. They will not be described in detail here.

[0056] Specifically, in this embodiment, two cable protection units 3 are provided, each corresponding to a screen support structure 22 to protect the cables used by the corresponding screen support structure 22. In other embodiments, one, three, or four cable protection units 3 are provided, etc. No limitation is made here.

[0057] Optionally, such as Figure 1 and Figure 4 As shown, the screen flipping structure 23 drives the screen supporting structure 22 to flip, and the output end of the film bonding unit 1 is located directly below the screen supporting structure 22, so that when the screen to be bonded and the film to be bonded are aligned, the film bonding unit 1 is surrounded within the space formed by the support frame 21 and the screen flipping structure 23. This enables the screen to be bonded and the film to be bonded to be quickly and accurately aligned, reducing bonding deviation, and does not require additional external space for the device, making the overall structure more compact and regular.

[0058] Optionally, such as Figures 2-5As shown, the cable protection unit 3 includes a protective sleeve 31 and a connecting component 32. The protective sleeve 31 houses the cable. The connecting component 32 includes a first connector 321 and a second connector 322. The first connector 321 is fixedly and adjustablely connected to the screen flip structure 23, and one end of the protective sleeve 31 is fixedly connected to the first connector 321. The second connector 322 is detachably and fixedly connected to the support frame 21. A through hole is provided on the second connector 322, and the other end of the protective sleeve 31 passes through and is fixedly connected to the through hole. Since the first connector 321 is fixedly and adjustablely connected to the screen flip structure 23, and the second connector 322 is detachably and fixedly connected to the support frame 21, the protective sleeve 31 can move relative to the screen flip structure 23. This ensures that the screen flip structure 23 can adjust the position of the first connector 321 and the second connector 322 during the flipping process, thereby reducing the pulling force on the protective sleeve 31 and the cables inside the protective sleeve 31. It also facilitates the subsequent inspection and replacement of the cables or the maintenance of the protective sleeve 31, taking into account both the adaptability of use and the convenience of later operation and maintenance.

[0059] Optionally, the protective sleeve 31 is made of a flexible material. Due to its high ductility, the flexible material can match the flipping trajectory of the screen flipping structure 23. Whether the screen flipping structure 23 flips clockwise or counterclockwise, the protective sleeve 31 can deform synchronously and follow the flip, without the rigidity of the material limiting the flipping angle of the screen flipping structure 23, and without causing pulling or crease damage to the protective sleeve 31. Simultaneously, the flexible protective sleeve 31 is placed on the outside of the cable, surrounding it and reducing interference and friction between the cable and other structures when the screen flipping structure 23 flips. Furthermore, when the cable follows the screen flipping structure 23, the protective sleeve 31 can also fit tightly against the cable sheath, dispersing the stress during cable bending, preventing cable breakage, and ensuring cable transmission stability. Specifically, in this embodiment, the protective sleeve 31 is made of rubber. In other embodiments, the protective sleeve 31 is made of silicone or latex, etc. No limitation is made here.

[0060] Optionally, such as Figures 3-6As shown, the connecting component 32 also includes a protective member 323. The first end of the protective member 323 is fixedly and adjustablely connected to the screen flip structure 23. The first connector 321 is fixedly connected to the first end of the protective member 323. The second end of the protective member 323 extends along the direction from the screen support structure 22 to the screen flip structure 23 and bends to form an arc-shaped end 3231. The protective sleeve 31 can abut against the outer wall surface of the arc-shaped end 3231. When the screen support structure 22 is not flipped 180 degrees, the arc-shaped outer wall surface of the arc-shaped end 3231 forms a surface contact with the outer wall surface of the protective sleeve 31, avoiding collision with the sharp edge of the screen flip structure 23 on the outer wall surface of the protective sleeve 31, which would cause the protective sleeve 31 to be compressed or worn. In addition, the extended arc-shaped end 3231 can reduce the jamming when the protective sleeve 31 is flipped, preventing the cables inside the protective sleeve 31 from bending when flipped, and ensuring the appearance and functional integrity of the cables.

[0061] Optionally, such as Figure 4 and Figure 5 As shown, the cable protection unit 3 also includes a limiting cylinder 33, which is fixedly connected to the support frame 21 and located above the second connector 322. The protective sleeve 31 can bypass the outer wall of the limiting cylinder 33 and be fixedly connected to the inner wall of the through hole. When the screen support structure 22 is not rotated 180 degrees, the outer wall of the limiting cylinder 33 is arc-shaped, forming a flexible support for the protective sleeve 31. This allows the protective sleeve 31, connected to the inner wall of the through hole, to be connected to the first connector 321 after being flexibly supported by the outer wall of the limiting cylinder 33. This prevents the protective sleeve 31 from directly turning from the inner wall of the through hole and connecting to the first connector 321, thereby preventing bending at the connection between the protective sleeve 31 and the second connector 322, which could lead to the cable inside the protective sleeve 31 being squeezed at the connection. Guided by the arc-shaped outer wall, the normal rotation of the protective sleeve 31 is ensured, as well as the integrity of the cable and the stability of the cable signal transmission are guaranteed.

[0062] Optionally, such as Figure 4 and Figure 5As shown, the limiting cylinder 33 includes a cylinder body 331 and limiting parts 332. The cylinder body 331 is fixedly connected to the support frame 21. The protective sleeve 31 passes around the outer peripheral wall of the cylinder body 331 and is fixedly connected to the through hole. Two limiting parts 332 are provided, and the two limiting parts 332 are fixedly connected to both ends of the cylinder body 331 along its axial direction. The limiting parts 332 can limit the offset of the protective sleeve 31 along the axial direction of the cylinder body 331. By setting the limiting parts 332, the movement of the protective sleeve 31 along the axial direction of the cylinder body 331 is restricted in both directions, avoiding the axial sliding or displacement of the cylinder body 331 during the flipping process of the protective sleeve 31. This ensures the stability of the fixed connection between the protective sleeve 31 and the inner wall of the through hole, and avoids the loosening of the connection caused by the offset of the protective sleeve 31 along the axial direction of the cylinder body 331, which would lead to the failure of the protective sleeve 31 to protect the cable.

[0063] Specifically, such as Figure 4 and Figure 5 As shown, the limiting part 332 is a non-closed annular limiting plate. In other embodiments, the limiting part 332 may be a non-closed limiting frame or a limiting rod, etc. No limitation is made here.

[0064] Optionally, such as Figure 3 , Figure 6 and Figure 7 As shown, the first end of the protective component 323 has an elongated hole 3232 extending along the direction from the screen support structure 22 to the screen flip structure 23. The screen flip structure 23 has a fixing hole. The automatic bonding device also includes a fixing member. One end of the fixing member passes through the elongated hole 3232 and is connected to the fixing hole, while the other end of the fixing member can abut against the first end of the protective component 323. With the elongated hole 3232, when one end of the fixing member passes through the elongated hole 3232 and is connected to the fixing hole, the elongated hole 3232 can move along the direction from the screen support structure 22 to the screen flip structure 23. When it moves to a preset position, the other end of the fixing member abuts against the first end of the protective component 323, fixing the position of the protective component 323, and thus fixing the position of the first connecting member 321, thereby improving the flexibility and stability of the connection between the protective component 323 and the screen flip structure 23.

[0065] Specifically, in this embodiment, the fastener is a bolt. In other embodiments, the fastener is a snap-fit ​​rod, etc. No limitation is made here.

[0066] Optionally, such as Figure 7As shown, the first end of the protective component 323 has multiple through holes 3233, which are spaced apart along the direction from the screen support structure 22 to the screen flip structure 23, allowing cables to pass through them. By providing multiple through holes 3233, cables in the protective sleeve 31 can pass through them, achieving directional cable routing and optimizing the cable path from the protective sleeve 31 to the subsequent structure. Furthermore, the spaced through holes 3233 prevent cable tangling and provide some limiting protection for the cables.

[0067] This embodiment also provides an automatic lamination device, which includes a feeding device, a discharging device, and an automatic lamination device. The feeding device is configured to place the film to be laminated and the screen to be laminated onto the output end of the film lamination unit 1 and the screen support structure 22, respectively. The discharging device is configured to pick up the screen to be laminated with the film to be laminated. By applying the automatic lamination device, when the screen support structure 22 repeatedly flips and drives the cable protection unit 3 to flip synchronously, and in conjunction with the feeding and discharging devices to load and unload the film to be laminated and the screen to be laminated, the cables are protected by the cable protection unit 3, avoiding cable damage, ensuring the reliability of the automatic lamination device, extending the service life of the automatic lamination device, and improving the production efficiency of the automatic lamination device.
