Obviously, the embodiments described below are only a part of the embodiments of this utility model, and not all of them.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] This utility model provides a magnetic traction roller bonding device.

[0034] like Figures 1 to 5 As shown, Figure 1 This is an isometric side view of the surround screen bonding device in this embodiment. Figure 2 This is the positioning and adjustment mechanism of the jig for the surround screen bonding equipment in this embodiment. Figure 3 This is the stretching mechanism of the surround screen bonding device in this embodiment. Figure 4 This is the strapping assembly mechanism of the surround screen bonding device in this embodiment. Figure 5This is the electromagnet traction mechanism of the surround screen bonding device in this embodiment.

[0035] The magnetic traction roller bonding equipment provided by this utility model can solve the problems of poor manual bonding effect of the wrap-around screen, low bonding degree between the wrap-around screen and the protective film, and low production efficiency.

[0036] like Figure 1 As shown, a magnetic traction roller bonding device includes a frame 1 and a fixture positioning and adjustment mechanism 2. The fixture positioning and adjustment mechanism 2 is fixed on the frame 1. The fixture positioning and adjustment mechanism 2 positions and clamps the surrounding screen and adjusts the position of the surrounding screen in the X direction.

[0037] The strap-threading assembly 4 is fixed to one side of the fixture positioning and adjustment mechanism 2. The strap-threading assembly 4 includes a fixed roller 46.

[0038] The stretching mechanism 3 is fixed on one side of the strapping assembly mechanism 4. The stretching mechanism 3 is used to fix and stretch the guide protective film, and the end of the protective film overlaps the fixed roller 46.

[0039] Electromagnetic traction mechanism 5 is fixed on the other side of fixture positioning and adjustment mechanism 2, and is used to attach the protective film in place to the surrounding screen.

[0040] Specifically, such as Figure 1 As shown, the fixture positioning and adjustment mechanism 2 positions and clamps the surround screen. The first adjustment device 23 adjusts the position of the surround screen on the X-axis to ensure it reaches a predetermined, accurate position in the X direction. The fixed roller 46 overlaps the protective film, guiding it to smoothly cover the surround screen. The stretching mechanism 3 fixes and stretches the protective film, with one end overlapping the fixed roller 46 and covering the surround screen. Once the protective film reaches the predetermined position, the electromagnet traction mechanism 5 on the other side of the fixture positioning and adjustment mechanism 2 uses magnetic force to guide the bonding device on the fixture positioning and adjustment mechanism 2 to bond the protective film to the surround screen, ensuring a tight and accurate bond to guarantee bonding quality.

[0041] Therefore, in the magnetic traction roller bonding equipment of this utility model, the various mechanisms cooperate with each other during the entire operation process to ensure that the protective film can be accurately and tightly bonded to the surrounding screen, and the position and height can be precisely controlled, making the bonding process highly automated, efficient, and ensuring bonding quality.

[0042] Furthermore, such as Figure 2As shown, the fixture positioning and adjustment mechanism 2 includes a fixture support plate 21. A rubber-coated fixture 22, a first guide wheel trajectory guide plate 24, a second guide wheel trajectory guide plate 26, and a first adjustment device 23 are fixed on the fixture support plate 21. The first guide wheel trajectory guide plate 24 is mounted on the fixture support plate 21 and is located on one side of the rubber-coated fixture 22. The first adjustment device 23 is fixed on the other side of the rubber-coated fixture 22, and the first adjustment device 23 adjusts the position of the surrounding screen in the X direction.

[0043] The second guide wheel track guide plate 26 and the moving end of the first adjustment device 23 are fixedly connected, and guide grooves are provided on both the first guide wheel track guide plate 24 and the second guide wheel track guide plate 26.

[0044] Specifically, the wraparound screen is placed on the overlay fixture 22. The first adjustment device 23 adjusts the position of the wraparound screen in the X direction to adapt to products of different sizes. During this process, when the first adjustment device 23 adjusts the position of the wraparound screen in the X-axis direction, the second guide wheel track guide plate 26 moves synchronously with the first adjustment device 23. The first guide wheel track guide plate 24, the second guide wheel track guide plate 26 and the first adjustment device 23 cooperate to guide and control the adjustment trajectory, ensuring that the wraparound screen always stays on the correct movement path during the adjustment process, preventing deviation, and thus ensuring the precise bonding position of the wraparound screen and the protective film.

[0045] Furthermore, such as Figure 2 As shown, the fixture positioning and adjustment mechanism 2 also includes a guide roller 25. The two ends of the guide roller 25 are slidably connected in the guide grooves of the first guide wheel track guide plate 24 and the second guide wheel track guide plate 26, respectively, for rolling and bonding of the protective film.

[0046] Specifically, the two ends of the guide roller 25 are located in the guide grooves of the first guide roller track guide plate 24 and the second guide roller track guide plate 26, respectively, so that the roller can roll smoothly. With the cooperation of the first guide roller track guide plate 24, the second guide roller track guide plate 26 and the first adjustment device 23, the guide roller 25 completes the bonding of the protective film and the surrounding screen by rolling, which reduces the friction of the protective film and the problem of uneven pressure distribution, and improves the bonding efficiency and quality.

[0047] Furthermore, such as Figure 3 As shown, the stretching mechanism 3 includes a fixed support plate 31, a first electric slide 32 is fixed on the fixed support plate 31, a gripper cylinder 34 is fixedly connected to one side of the first electric slide 32, and a clamp 33 is provided on the gripper cylinder 34.

[0048] When the protective film is clamped onto the clamp 33, the gripper cylinder 34 clamps it, and the protective film is stretched under the drive of the first electric slide 32.

[0049] Specifically, such as Figure 3 As shown, when the protective film is clamped on the clamp 33, one end of the protective film extends out and overlaps the fixed roller 46. At the same time, the gripper cylinder 34 clamps the clamp 33 tightly, holding the protective film firmly. The first electric slide 32 stretches the clamped protective film along the Z direction, ensuring that the protective film is stretched accurately, avoiding unevenness during the stretching process, and ensuring the stability and accurate positioning of the protective film, thus improving work efficiency.

[0050] Furthermore, such as Figure 4 As shown, the strapping assembly mechanism 4 includes a first support plate 41, a slide cylinder 42 is fixed on the upper surface of the first support plate 41, a fixing plate 43 is provided below the first support plate 41, and a second electric slide 44 is fixed on one side of the fixing plate 43. The second electric slide 44 is used to adjust the position of the protective film on the Y-axis.

[0051] Specifically, such as Figure 4 As shown, the second electric slide 44 can guide the protective film to be accurately positioned on the Y-axis by adjusting the position of the protective film on the Y-axis, ensuring that the protective film is bonded at the correct height and improving the bonding yield of the wraparound screen product.

[0052] Furthermore, a second support plate 48 is installed on the upper end face of the slide cylinder 42, and a pressure plate 47 is provided on the second support plate 48. The pressure plate 47 is used to fix the release film in the protective film.

[0053] The second electric slide 44 is fixedly provided with a first roller fixing plate 45, which is fixedly connected to the fixed roller 46.

[0054] Specifically, the pressure plate 47 adjusts the position of the release film in the protective film on the Z-axis as the slide cylinder 42 moves, specifically away from the fixture positioning adjustment mechanism 2, so that the protective film moves smoothly during the bonding process with the surrounding screen, avoiding wrinkles or bubbles. The first roller fixing plate 45 adjusts its height as the second electric slide 44 moves, ensuring that the height of the fixing roller 46 matches the height of the surrounding screen, guiding the protective film to cover the surrounding screen, making the guidance and positioning of the protective film on the Z-axis precise and efficient, thereby improving operating efficiency and bonding quality.

[0055] Furthermore, such as Figure 5 As shown, the electromagnet traction mechanism 5 includes a second adjustment device 51, a third adjustment device 52 fixed on the second adjustment device 51, a second roller fixing plate 53 fixed on one side of the third adjustment device 52, and a magnet guide roller 54 fixedly connected to the second roller fixing plate 53.

[0056] The second adjustment device 51 and the third adjustment device 52 adjust the position of the magnet guide roller 54 in the Y-axis and Z-axis directions. The magnet guide roller 54 is used to attach the protective film to the surround screen.

[0057] Specifically, after the protective film is guided to the bonding position, the operating system adjusts the positions of the second adjustment device 51 and the third adjustment device 52 through electronic control commands, so that the magnetic guide roller 54 is aligned with the bonding starting point of the protective film and the surrounding screen. After the magnetic guide roller 54 is energized, it generates magnetic force and begins to roll in a circular motion. Under the action of the magnetic guide roller 54, the guide roller 25 and the magnetic guide roller 54 roll in a synchronous circular motion, ensuring uniform pressure when the protective film is bonded, avoiding the generation of bubbles and wrinkles, thereby improving operating efficiency and bonding quality.

[0058] The aforementioned adjustment device may be a screw adjustment mechanism, a slider adjustment mechanism, an electric adjustment mechanism, or other structures, and is not limited in this embodiment.

[0059] To facilitate understanding by those skilled in the art, the overall working process of the magnetic traction roller bonding equipment will be explained below:

[0060] The fixture positioning and adjustment mechanism 2 positions and clamps the surround screen. The first adjustment device 23 adjusts the position of the surround screen on the X-axis to ensure that the position of the surround screen in the X direction is accurate and that the surround screen reaches the predetermined accurate position in the X direction. When the protective film is placed on the clamp 33 by the worker, the gripper cylinder 34 is activated, so that the protective film is clamped in the clamp 33. Then, the worker manually overlaps and fixes one end of the protective film on the roller 46, presses the release film in the protective film into the pressure plate 47, and wraps the adhesive film in the protective film around the guide roller 25.

[0061] Next, the first electric slide 32 stretches the clamped protective film along the Z-axis, specifically away from the fixture positioning and adjustment mechanism 2. The fixed roller 46, along with the second electric slide 44, adjusts the position of the protective film on the Z-axis to ensure accurate coverage of the wraparound screen. The slide cylinder 42 adjusts the position of the pressure plate 47 on the Z-axis, fixing the release film within the protective film and allowing it to move smoothly during bonding with the wraparound screen, avoiding wrinkles or bubbles. After the protective film is guided to the bonding position, the positions of the second adjustment device 51 and the third adjustment device 52 are adjusted, causing the magnetic guide roller 54 to align with the bonding starting point of the protective film and the wraparound screen. The magnetic guide roller 54, guided by magnetic force, performs synchronous circular rolling, ensuring the protective film is tightly bonded to the wraparound screen and accurately positioned, thus bonding the protective film and the wraparound screen together to guarantee bonding quality.

[0062] During this process, the various mechanisms cooperate with each other to ensure that the protective film can be accurately and tightly adhered to the surrounding screen, and that its position and height can be precisely controlled, making the bonding process highly automated, efficient, and ensuring bonding quality.

[0063] In summary, the magnetic traction roller bonding equipment of this utility model has the advantages of precise adjustment of bonding path, improved bonding yield of surround screen products, increased production efficiency and reduced manual intervention.

[0064] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
