Description

Technical Field

[0001] This utility model relates to the field of bonding fixture technology, specifically a mobile phone touch screen bonding fixture. Background Technology

[0002] A mobile phone touchscreen bonding fixture is a tool or device specifically designed to precisely align and securely bond a touchscreen to a display panel (or other related components). It plays a crucial role in mobile phone manufacturing and repair, ensuring a perfect fit between screen components, thereby guaranteeing the functionality and aesthetic quality of the final product.

[0003] Chinese patent (authorization announcement number: CN 213382988 U, authorization announcement date: 2021.06.08) proposes a mobile phone touch screen bonding fixture. The present invention uses a move-and-lock mechanism to restrict the circumferential movement of the slide table by rotating screw one and slide groove one, thereby driving the slide table to move. After the slide table moves, it is immediately locked by the cooperation of screw one and screw sleeve, which can effectively prevent the slide table from moving when the base is impacted, thus preventing it from affecting the film bonding.

[0004] When the above-mentioned device is used to bond a mobile phone touch screen, the mobile phone is squeezed tightly in the placement slot. After the bonding of the mobile phone touch screen is completed, it is very inconvenient to pick up and put down the mobile phone, which affects the bonding efficiency of the next mobile phone touch screen and reduces the practicality of the device. In order to improve the bonding efficiency of the mobile phone touch screen of the above-mentioned device, we propose a mobile phone touch screen bonding fixture. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mobile phone touchscreen bonding fixture. A horizontal adjustment groove and a vertical adjustment groove are respectively provided on the left and right sides and the front and rear sides of the top of the touchscreen fixing box. A horizontal baffle is provided on the horizontal adjustment groove, and a vertical baffle is provided on the vertical adjustment groove. A bidirectional screw rod 1 and a bidirectional screw rod 2 are rotatably inserted between the left and right sides and between the front and rear sides of the inner wall of the touchscreen fixing box. A horizontal adjustment component and a vertical adjustment component are respectively installed on the bidirectional screw rod 1 and the bidirectional screw rod 2. The spacing between the two sets of horizontal baffles and the spacing between the two sets of vertical baffles are adjusted according to the size of the mobile phone touchscreen using the horizontal and vertical adjustment components. A lifting component is installed in the middle of the touchscreen fixing box. When bonding is required, the mobile phone touchscreen is bonded using a pressing assembly installed between mounting plate one and mounting plate two. During bonding, a linkage lifting assembly lowers the horizontal baffle, vertical baffle, and top plate, making the top plate flush with the top side of the touchscreen mounting box. This ensures even force distribution on the touchscreen during bonding. After bonding is complete, the top plate lifts the touchscreen, facilitating its removal and placement, thus improving the bonding efficiency of the device. The lowering distance of the horizontal and vertical baffles can be adjusted in the linkage lifting assembly, and the distance between the pressing roller and the surface of the touchscreen mounting box can be adjusted in the pressing assembly. This allows for bonding touchscreens of different thicknesses, improving the device's practicality and solving the background problem.

[0031] In use, the device adjusts the spacing of the two sets of horizontal baffles 30 and the two sets of vertical baffles 46 according to the size of the mobile phone touchscreen using the horizontal adjustment component and the vertical adjustment component respectively. A lifting component is installed in the middle of the touchscreen fixing box 51 to lift the mobile phone touchscreen that is held in place by the two sets of horizontal baffles 30 and the two sets of vertical baffles 46. When bonding is required, the pressing component installed between the mounting plate 1 2 and the mounting plate 2 3 is used to bond the mobile phone touchscreen. During bonding, the horizontal baffles 30, the vertical baffles 46 and the lifting component are lowered simultaneously by the linkage lifting component, so that the lifting component is flush with the top side of the touchscreen fixing box 51, so that the mobile phone touchscreen is subjected to uniform force during bonding. After bonding is completed, the lifting component lifts the mobile phone touchscreen, making it easy to put on and take off the mobile phone touchscreen and improving the bonding efficiency of the device.

[0032] The lifting assembly includes a top plate lifting groove 18, which is located in the middle of the top side of the touch screen fixing box 51.

Several telescopic rods 19 are provided between the bottom side of the top plate 15 and the bottom inner wall of the top plate lifting groove 18. Springs 20 are sleeved on the telescopic rods 19.

[0033] The lateral adjustment assembly includes two sets of movable plates 47. The front ends of the two sets of movable plates 47 are respectively threaded onto the left and right sides of the bidirectional screw 22.

[0034] The longitudinal adjustment assembly includes two sets of movable plates 42, which are threaded onto the front and rear sides of the bidirectional screw 23, respectively. A limiting rod 45 is fixedly connected between the front and rear inner walls of the touch screen fixing box 51.

[0035] When the mobile phone touchscreen is ready to be attached, the touchscreen is placed on the top plate 15. Inside the top plate lifting groove 18, the top plate 15, under the action of the telescopic rod 19 and the spring 20, lifts the touchscreen above the top side of the touchscreen fixing box 51. The sliders 16 on the left and right sides of the top plate 15 slide on the sliding holes 17, and are limited to prevent the top plate 15 from detaching. By rotating the bidirectional screw 22 through the horizontal adjustment knob 8, the two sets of moving plates 47 move closer or further away from each other on the bidirectional screw 22, thereby driving the two sets of linkage plates 50 and the two sets of horizontal baffles 30 to move closer or further away from each other, thus tightening and limiting the left and right sides of the touchscreen. By rotating the bidirectional screw 23 through the vertical adjustment knob 9, the two sets of moving plates 42 move closer or further away from each other, thereby driving the two sets of linkage plates 44 and the two sets of vertical baffles 46 to move closer or further away from each other, thus tightening and limiting the front and rear sides of the touchscreen.

[0036] The linkage lifting assembly includes a cross plate 25, with lifting rods 26 fixedly connected to both the left and right ends of the cross plate 25. Lifting rods 27 are fixedly connected to both the front and rear ends of the cross plate 25. The rear ends of two sets of linkage plates 20 are slidably fitted onto the two sets of lifting rods 26, and the right ends of two sets of linkage plates 44 are slidably fitted onto the two sets of lifting rods 27. Telescopic lifting slots 28 are provided between the mounting plate 20 and the touchscreen mounting box 51, and between the mounting plate 20 and the touchscreen mounting box 51. The top of the plate lifting groove 28 is slidably connected to a telescopic plate 21. Springs 29 are provided between the bottom left and right sides of the two sets of telescopic plates 21 and the inner wall of the telescopic plate lifting groove 28. Two sets of connecting rods 33 and two sets of limiting rods 34 are fixedly connected to the bottom sides of the two sets of telescopic plates 21. Connecting rods 24 are fixedly connected to the side of the two sets of sliders 16 away from the top plate 15. The front and rear ends of the two sets of connecting rods 24 are fixedly connected to the connecting rods 33. An adjustment mechanism is also installed between the two sets of telescopic plates 21.

[0037] The adjustment mechanism includes two sets of lifting plates 35. The left and right ends of the lifting plates 35 are slidably sleeved on the limiting rods 34. The ends of the two sets of lifting rods 27 away from the top plate 15 are respectively fixedly connected to the side of the two sets of lifting plates 35 near the top plate 15. A screw 32 is rotatably inserted on one set of telescopic plates 21. One set of lifting plates 35 is threaded onto the screw 32. The top end of the screw 32 is fixedly connected to an internal hexagonal knob 31.

[0038] The pressing assembly includes two sets of sliding plates 4, with a fixed plate fixedly connected between the two sets of sliding plates 4. Slide grooves 37 are provided on the right side of both mounting plate 1 2 and mounting plate 2 3. Slider 2 36 is fixedly connected to the bottom right side of both sets of sliding plates 4. The two sets of slider 2 36 are slidably connected to the two sets of slide grooves 37. A screw 38 is rotatably threaded through one set of slide grooves 37. One set of slider 2 36 is threaded onto the screw 38. A drive motor 41 is fixedly installed on the rear right side of mounting plate 1 2. Pulleys 39 are fixedly connected to the output shaft end of the drive motor 41 and the right end of the screw 38. A belt 40 is tensioned between the two sets of pulleys 39. A roller pressing mechanism is installed between the two sets of sliding plates 4.

[0039] The roller pressing mechanism includes a lifting plate 5. A limit rod 6 is fixedly connected to the top left side of one set of sliding plates 4. The rear end of the lifting plate 5 is slidably sleeved on the limit rod 6. A screw 10 is rotatably installed on the top left side of the other set of sliding plates 4. The front end of the lifting plate 5 is threadedly sleeved on the screw 10. A lifting adjustment knob 11 is fixedly connected to the top end of the screw 10. Connecting plates 12 are fixedly connected to the front and rear sides of the bottom of the lifting plate 5. A fixing rod 13 is fixedly connected between the two sets of connecting plates 12. A pressing roller 14 is rotatably sleeved on the fixing rod 13.

[0040] When the mobile phone touchscreen is attached, the drive motor 41 rotates the pulley 39, and the belt 40 rotates another set of pulleys 39, thereby rotating the screw 38. This causes a set of sliders 36 threaded onto the screw 38 to slide on the corresponding groove 37, which in turn drives the sliding plate 4 on the top side of the mounting plate 2 to slide. Since a fixed plate is fixedly connected between the two sets of sliding plates 4, the two sets of sliding plates 4 slide synchronously. When the sliding plate 4 contacts the telescopic plate 21, it presses the telescopic plate 21 into the telescopic plate lifting groove 28, thereby driving the two sets of lifting plates 35 to descend synchronously. This, in turn, drives the two sets of lifting rods 27 and the cross plate 25 to descend synchronously, as well as the two sets of lifting rods 26 to descend synchronously. This also drives the two sets of linkage plates 50 and 44 to slide on the sliders 48 and 44 respectively. The upper plate 15 slides down synchronously, ultimately achieving the synchronous descent of the two sets of horizontal baffles 30 and the two sets of vertical baffles 46. Connected by two sets of connecting rods 23 and 24, the top plate 15 descends synchronously until it is flush with the top side of the touchscreen mounting box 51. At this point, the pressing roller 14 contacts the top side of the touchscreen to achieve pressing, preventing uneven force on the top plate 15. The lifting plate 35 is raised and lowered by rotating the screw 32 using the hexagonal knob 31, thereby adjusting the extension length of the two sets of horizontal baffles 30 and the two sets of vertical baffles 46. The lifting plate 5 is raised and lowered by rotating the screw 10 using the lifting adjustment knob 11, thus adjusting the distance between the pressing roller 14 and the top side of the touchscreen mounting box 51. This adapts to bonding touchscreens of different thicknesses, improving the practicality of the device.

[0041] Several rubber pads 7 are fixedly connected to the top side of the touch screen mounting box 51 to prevent the bottom of the mobile phone touch screen from being damaged when it is attached.

[0042] Elastic pads are fixedly connected to the top side of the top plate 15, the side of the two sets of horizontal baffles 30 that are close to each other, and the side of the two sets of vertical baffles 46 that are close to each other, which cushions the four sides of the mobile phone touch screen.

[0043] Anti-slip pads are fixedly connected to the four corners of the bottom of the workbench 1 to prevent the workbench 1 from sliding.

[0044] Working principle: When the device is in use, when the mobile phone touch screen is ready to be attached, the mobile phone touch screen is placed on the top plate 15. The top plate 15 is inside the top plate lifting groove 18. Under the action of the telescopic rod 19 and the spring 20, the mobile phone touch screen is lifted higher than the top side of the touch screen fixing box 51. The sliders 16 on the left and right sides of the top plate 15 slide on the sliding holes 17 and are limited to prevent the top plate 15 from falling off. By rotating the bidirectional screw 22 through the horizontal adjustment knob 8, the two sets of moving plates 47 move closer or further away from each other on the bidirectional screw 22, thereby driving the two sets of linkage plates 50 and the two sets of horizontal baffles 30 to move closer or further away from each other, thus tightening and limiting the left and right sides of the mobile phone touch screen. By rotating the bidirectional screw 23 through the vertical adjustment knob 9, the two sets of moving plates 42 move closer or further away from each other, thereby driving the two sets of linkage plates 44 and the two sets of vertical baffles 46 to move closer or further away from each other, thus tightening and limiting the front and rear sides of the mobile phone touch screen.

[0045] When the mobile phone touchscreen is attached, the drive motor 41 rotates the pulley 39, and the belt 40 rotates another set of pulleys 39, thereby rotating the screw 38. This causes a set of sliders 36 threaded onto the screw 38 to slide on the corresponding groove 37, which in turn drives the sliding plate 4 on the top side of the mounting plate 2 to slide. Since a fixed plate is fixedly connected between the two sets of sliding plates 4, the two sets of sliding plates 4 slide synchronously. When the sliding plate 4 contacts the telescopic plate 21, it presses the telescopic plate 21 into the telescopic plate lifting groove 28, thereby driving the two sets of lifting plates 35 to descend synchronously. This, in turn, drives the two sets of lifting rods 27 and the cross plate 25 to descend synchronously, as well as the two sets of lifting rods 26 to descend synchronously. This also drives the two sets of linkage plates 50 and 44 to slide on the sliders 48 and 44 respectively. The upper plate 15 slides down synchronously, ultimately achieving the synchronous descent of the two sets of horizontal baffles 30 and the two sets of vertical baffles 46. Connected by two sets of connecting rods 23 and 24, the top plate 15 descends synchronously until it is flush with the top side of the touchscreen mounting box 51. At this point, the pressing roller 14 contacts the top side of the touchscreen to achieve pressing, preventing uneven force on the top plate 15. The lifting plate 35 is raised and lowered by rotating the screw 32 using the hexagonal knob 31, thereby adjusting the extension length of the two sets of horizontal baffles 30 and the two sets of vertical baffles 46. The lifting plate 5 is raised and lowered by rotating the screw 10 using the lifting adjustment knob 11, thus adjusting the distance between the pressing roller 14 and the top side of the touchscreen mounting box 51. This adapts to bonding touchscreens of different thicknesses, improving the practicality of the device.
