Description

Technical Field

[0001] This invention relates to the field of touch screen installation, and more particularly to a screen bonding device. Background Technology

[0002] A touchscreen, also known as a touch panel, is a sensor-based liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. As a new type of computer input device, the touchscreen is currently the simplest, most convenient, and most natural way of human-computer interaction.

[0003] Chinese invention patent (CN110685983B) discloses a screen bonding device and a screen bonding method. The proposed screen bonding device uses a robotic gripper to grasp and move the display screen, avoiding the problem of screen damage caused by manual handling. The robotic gripper moves the display screen according to the position difference collected by the vision device, so that the display screen is accurately bonded to the backlight module. However, this screen bonding device requires a conveying device to transport the backlight module to the initial positioning station. The initial positioning station adjusts the position of the backlight module once. After the adjustment, the conveying device transports the display module to the bonding station for a second position adjustment. The display module is fixed in the bonding station. The conveying device and the initial positioning station are relatively independent. The error between the placement position of the display module and the initial positioning station is large, which requires multiple drive control, makes the structure more complex, and makes it difficult to control synchronously. This results in long positioning time and affects production. In order to solve the existing problems, a screen bonding device is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the conveying device and the initial positioning station are relatively independent, requiring multiple drive controls, and to propose a screen bonding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a screen bonding device, including two substrates, connecting rods, and a screen supply mechanism. The screen supply mechanism includes a first base, an outer rotating shaft, and a rotating frame. The first base is fixedly installed at both ends of a movable groove. The outer rotating shaft is rotatably installed inside the first base. The rotating frame is fixedly installed between the two outer rotating shafts. A screen shifting mechanism is provided in the rotating frame. A side conveying mechanism is provided between the two substrates. The side conveying mechanism includes four sets of fixed rods and second pulleys. Each set of fixed rods is slidably installed in a movable groove. Each second pulley is rotatably installed between each set of fixed rods. A conveyor belt is driven and sleeved on every two horizontally arranged second pulleys.

[0007] Preferably, the screen-shifting mechanism includes a first bidirectional screw, two movable seats, two sets of hinged rods, and an inner push plate. The first bidirectional screw is rotatably mounted in the middle of the rotating frame. The two movable seats are threadedly sleeved on the first bidirectional screw. The two sets of hinged rods are hingedly mounted at both ends of the two movable seats. The inner push plate is hingedly mounted at the other end of each set of hinged rods. Push rods are fixedly mounted in an array on the outer side of the inner push plate, and the push rods pass through the rotating frame to fix a vent box. A first suction cup is arranged in an array on the outer side of the vent box.

[0008] Preferably, a first motor is fixedly installed on the inner side of one end of the rotating frame, and gears are fixedly installed on the output shaft of the first motor and the first bidirectional screw, and they mesh with each other for transmission.

[0009] Preferably, each of the horizontally arranged fixing rods is provided with a connecting plate, and a second motor is fixedly installed on one of the connecting plates.

[0010] Preferably, it further includes a conversion mechanism, which includes a second base and a second bidirectional screw. The second base is fixedly installed at the upper and lower ends of the movable groove, and the second bidirectional screw is vertically rotatably installed in the middle of the second base. The second bidirectional screw is threadedly connected to the fixed rod.

[0011] Preferably, a lifting seat is fixedly sleeved on the outer end of the second motor, and slide rods are fixedly installed on both sides of the slide groove, and the lifting seat slides on the slide rods.

[0012] Preferably, a limiting frame is fixedly installed on one side of the connecting plate, and rollers are rotatably mounted on the limiting frame.

[0013] Preferably, a limiting plate is fixedly installed on the inner side of one of the connecting plates.

[0014] Preferably, it also includes a limiting mechanism, which includes a mounting plate, a telescopic cylinder, a movable plate, and a telescopic rod. The mounting plate is fixedly installed in the middle of the observation slot. The telescopic cylinder is arranged in an array on the mounting plate. The movable plate is fixedly installed at the other end of the telescopic cylinder. A second suction cup is fixedly arranged on the movable plate corresponding to the telescopic cylinder. The telescopic rod is fixedly installed in an array on the mounting plate. The telescopic end of the telescopic rod is fixedly connected to the movable plate.

[0015] Preferably, end plates are fixedly installed at both ends of the two substrates, and each end plate is provided with a feeding groove.

[0016] The screen bonding device proposed in this invention has the following advantages:

[0017] 1. By setting up a substrate, a screen supply mechanism, and a side conveying mechanism, on the one hand, the equipment is side-mounted and transported by the second pulleys and conveyor belts on the upper and lower sides, which significantly reduces the situation where the conveying and limiting are relatively independent before bonding in traditional equipment, thereby ensuring the screen bonding accuracy. On the other hand, the screen supply mechanism can realize continuous and synchronous screen picking and bonding through rotation, which is more efficient and convenient, while meeting the pressure required during screen bonding, significantly reducing the time required for the screen bonding process in traditional screen installation equipment.

[0018] 2. A conversion mechanism is set up to adjust the spacing between the upper and lower conveyor belts, thereby adapting to the installation of screens of mobile phones and tablets of different models and sizes. At the same time, the clamping pressure of the upper and lower conveyor belts on the screen to be installed can be finely adjusted, making it more versatile and also easy to adjust the limit.

[0019] 3. By setting a limiting mechanism, on the one hand, the screen device to be installed can be assisted in limiting and fixing before installation, so that it is in close contact with the roller, which facilitates the subsequent screen installation and positioning. On the other hand, during screen installation, it can prevent the screen device to be installed from shifting to the side, which would cause screen misalignment and make the installation more accurate.

Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0030] Reference Figure 1-8A screen bonding device includes two substrates 1, connecting rods 2, and a screen supply mechanism 3. The connecting rods 2 are arrayed and fixedly installed between the two substrates 1. The screen supply mechanism 3 includes a first base 31, an outer rotating shaft 32, and a rotating frame 33. One of the substrates 1 has a movable slot 13, which facilitates the installation of the screen by the screen supply mechanism 3. The first base 31 is fixedly installed at both ends of the movable slot 13. The outer rotating shaft 32 is rotatably installed inside the first base 31. The rotating frame 33 is fixedly installed between the two outer rotating shafts 32. The rotating frame 33 is a frame structure. A servo motor 35 is fixedly installed on the outside of one of the first bases 31, and the output shaft of the servo motor 35 is fixedly connected to the outer rotating shaft 32. The servo motor 35 facilitates precise control of the rotation angle. A screen moving mechanism 34 is provided in the rotating frame 33, which can complete the screen picking and bonding installation. A side conveying mechanism 4 is provided between the two substrates 1. The side conveying mechanism 4 includes four sets of fixed rods 41 and a second pulley 42. The two substrates 1 are located on both sides. Each set of fixed rods 41 is provided with a moving groove 11. Each set of fixed rods 41 is slidably arranged in the moving groove 11. Each set of fixed rods 41 includes two fixed rods 41 arranged at intervals. Each second pulley 42 is rotatably installed in the middle of each set of fixed rods 41. A conveyor belt 43 is driven and sleeved on each pair of horizontally arranged second pulleys 42. Each set of horizontally arranged fixed rods 41 is provided with a connecting plate 44. The connecting plate 44 is fixedly connected to the fixed rod 41. A second motor 45 is fixedly installed on one of the connecting plates 44. A first pulley is fixedly installed on the output shaft of the second motor 45 and one end of the second pulley 42. A transmission belt is sleeved on the first pulley. The second motor 45 drives the second pulley 42 to rotate synchronously through the first pulley and the transmission belt, and synchronously controls the two second motors 45, so that the two conveyor belts 43 rotate synchronously in opposite directions. The screen device to be installed is inserted between the two conveyor belts 43, and the screen device to be installed is clamped and conveyed until the screen device to be installed moves to the predetermined position.

[0031] The screen-shifting mechanism 34 includes a first bidirectional screw 341, two movable seats 342, two sets of hinge rods 343, and an inner push plate 344. The first bidirectional screw 341 is rotatably mounted in the middle of the rotating frame 33. The two movable seats 342 are threadedly connected to the first bidirectional screw 341. Each set of hinge rods 343 includes two hinge rods 343, which are hinged to both ends of the two movable seats 342. The inner push plate 344 is hinged to the other end of each set of hinge rods 343. Push rods 345 are fixedly mounted in an array on the outer side of the inner push plate 344, and the push rods 345 pass through the rotating frame 33 and are fixedly mounted with a vent box 346. A first suction cup 347 is arranged in an array on the outer side of the vent box 346. A first motor 348 is fixedly mounted on the inner side of one end of the rotating frame 33. Gears are fixedly installed on the output shaft 48 and the first bidirectional screw 341 and mesh with each other for transmission. At this time, the servo motor 35 is started, which drives the outer rotating shaft 32 and the rotating frame 33 to rotate, so that the screen adsorbed on the first suction cup 347 on the outside of one of the ventilation boxes 346 is aligned with the screen device to be installed. At the same time, the first motor 348 is started, which drives the first bidirectional screw 341 to rotate through gear meshing transmission. Then the two moving seats 342 move towards each other, and push the ventilation box 346 and the first suction cup 347 to expand outward through the two sets of hinge rods 343, inner push plate 344, and push rod 345 to install the screen. At the same time, the device accurately adsorbs the screen onto the first suction cup 347 on the outside of the other ventilation box 346 for the next screen bonding and installation.

[0032] By setting up a substrate 1, a screen supply mechanism 3, and a side conveying mechanism 4, on the one hand, the equipment is side-mounted and transported by the second pulley 42 on the upper and lower sides and the conveyor belt 43, which significantly reduces the situation where the conveying and limiting are relatively independent before bonding in traditional equipment, thereby ensuring the screen bonding accuracy. On the other hand, the screen supply mechanism 3 can realize continuous and synchronous screen picking and bonding, which is more efficient and convenient, while meeting the pressure required during screen bonding, significantly reducing the time required for the screen bonding process in traditional screen installation equipment.

[0033] A limiting frame 46 is fixedly installed on one side of the connecting plate 44. Rollers 47 are rotatably mounted on the limiting frame 46. The limiting frame 46 and rollers 47 are set to facilitate lateral limiting of the screen device to be installed.

[0034] A limiting plate 48 is fixedly installed on the inner side of the connecting plate 44 on one side. The limiting plate 48 is in contact with the conveyor belt 43. The limiting plate 48 is set to avoid insufficient pressure on the screen device to be installed by the upper and lower conveyor belts 43, and at the same time, it helps to limit the screen device to be installed. When the screen device to be installed moves to the installation position, the limiting plate 48 helps to apply pressure to the screen device to be installed. End plates 7 are fixedly installed at both ends of the two base plates 1. Each end plate 7 is provided with a feeding groove 71. The end plates 7 are set to facilitate the accurate placement and removal of the screen device to be installed. Example

[0035] According to Embodiment 1, the equipment is side-mounted and transported by the upper and lower second pulleys 42 and conveyor belts 43, significantly reducing the independent transport and limiting of traditional equipment before bonding, thus ensuring screen bonding accuracy. The screen supply mechanism 3 enables continuous and synchronous screen picking and bonding, making it more efficient and convenient. It also meets the pressure required for screen bonding, significantly reducing the time required for the bonding process in traditional screen installation equipment. However, the spacing between the upper and lower conveyor belts 43 is not easily adjustable, making it difficult to adapt to adjusting the clamping pressure of the equipment to be installed on the screen. (Refer to...) Figure 1-8 As another preferred embodiment of the present invention, based on embodiment 1, a conversion mechanism 5 is also included.

[0036] The conversion mechanism 5 includes a second base 51 and a second bidirectional screw 52. The second base 51 is fixedly installed at the upper and lower ends of the moving groove 11. The second bidirectional screw 52 is vertically rotatably installed in the middle of the second base 51. The second bidirectional screw 52 is threadedly connected to the fixed rod 41. The upper and lower sides of the base plate 1 are provided with sliding grooves corresponding to the second motor 45. The outer end of the second motor 45 is fixedly fitted with a lifting seat 53. Slide rods 54 are fixedly installed on both sides of the sliding groove. The lifting seat 53 slides on the slide rods 54. When it is necessary to adjust the distance between the upper and lower conveyor belts 43, the second bidirectional screw 52 is rotated synchronously. Through the threaded connection between the second bidirectional screw 52 and the fixed rod 41, the connecting plate 44 is moved, thereby changing the distance between the upper and lower conveyor belts 43. At the same time, the lifting seat 53 and the slide rods 54 are provided to help limit the second motor 45 and prevent it from shaking.

[0037] The conversion mechanism 5 is set up to adjust the distance between the upper and lower conveyor belts 43, so as to adapt to the installation of screens of mobile phones and tablets of different models and sizes. At the same time, the clamping pressure of the upper and lower conveyor belts 43 on the screen to be installed can be finely adjusted, making it more versatile and easy to adjust the limit. Example

[0038] According to Embodiment 2, the equipment is side-mounted and transported by the upper and lower second pulleys 42 and conveyor belts 43, significantly reducing the independent transport and limiting of traditional equipment before bonding, thus ensuring screen bonding accuracy. The screen supply mechanism 3 enables continuous and synchronous screen picking and bonding, making it more efficient and convenient. It also meets the pressure required for screen bonding, significantly reducing the time required for the bonding process in traditional screen installation equipment. However, the spacing between the upper and lower conveyor belts 43 is not easily adjustable, making it difficult to adapt to adjusting the clamping pressure of the device to be installed. A conversion mechanism 5 is provided to adjust the spacing between the upper and lower conveyor belts 43, thus adapting to the installation of screens for different models and sizes of mobile phones and tablets. However, when bonding the screen, the device to be installed is prone to lateral displacement due to force, resulting in insufficient pressure during screen bonding and affecting the bonding effect. (Refer to...) Figure 1-8 As another preferred embodiment of the present invention, based on embodiment 2, a limiting mechanism 6 is also included.

[0039] The limiting mechanism 6 includes a mounting plate 61, a telescopic cylinder 62, a movable plate 63, and a telescopic rod 64. An observation slot 12 is provided on another base plate 1. The mounting plate 61 is fixedly installed in the middle of the observation slot 12. An air passage is provided inside the mounting plate 61, and a vacuum pipe is connected to the outside of the mounting plate 61 and to the air passage. An array of telescopic cylinders 62 is connected to the mounting plate 61, and the telescopic cylinders 62 are connected to the air passage. The movable plate 63 is fixedly installed at the other end of the telescopic cylinders 62. A second suction cup 65 is fixedly provided on the movable plate 63 corresponding to the telescopic cylinders 62. An array of telescopic rods 64 are fixedly installed on the mounting plate 61. The telescopic rods 64 can be hydraulic telescopic rods, actuated telescopic rods, or electric push rods. The telescopic end of the telescopic rod 64 is fixedly connected to the movable plate 63. When the screen device to be installed moves to a predetermined position, the telescopic rod 64 is extended, pushing the movable plate 63 and the second suction cup 65 to move and fit against the screen device. At this time, the vacuum pipe outside the mounting plate 61 performs suction, thereby causing the second suction cup 65 to adsorb the screen device to be installed, thus limiting and fixing it.

[0040] By setting the limiting mechanism 6, on the one hand, it can assist in limiting and fixing the screen device to be installed before installation, so that it is in close contact with the roller 47, thereby facilitating the subsequent screen installation and positioning. On the other hand, it can prevent the screen device to be installed from shifting to the side during screen installation, thus avoiding screen installation misalignment and making the accuracy higher.

[0041] Working principle: The second motor 45 drives the second pulley 42 to rotate synchronously through the first pulley and the transmission belt, and synchronously controls the two second motors 45, so that the two conveyor belts 43 rotate synchronously in opposite directions. The screen to be installed is inserted between the two conveyor belts 43, and the screen to be installed is clamped and transported until the screen to be installed moves to the predetermined position. At this time, the servo motor 35 is started, driving the outer rotating shaft 32 and the rotating frame 33 to rotate, so that the screen adsorbed on the first suction cup 347 on the outside of one of the ventilation boxes 346 is aligned with the screen to be installed. At the same time, the first motor 348 is started, driving the first bidirectional screw 341 to rotate through gear meshing transmission. Then the two moving seats 342 move towards each other, through two sets of hinge rods 343, inner push plate 344, and push rod. 345 pushes the ventilation box 346 and the first suction cup 347 outward to install the screen. At the same time, the screen is precisely adsorbed onto the first suction cup 347 on the outside of another ventilation box 346 by the equipment, so that the screen can be attached and installed next time. When it is necessary to adjust the distance between the upper and lower conveyor belts 43, the second bidirectional screw 52 is rotated synchronously. The second bidirectional screw 52 is threadedly connected to the fixing rod 41, which drives the connecting plate 44 to move, thereby changing the distance between the upper and lower conveyor belts 43. When the screen to be installed moves to the predetermined position, the telescopic rod 64 is extended to push the moving plate 63 and the second suction cup 65 to move and attach to the screen to be installed. At this time, the vacuum pipe on the outside of the mounting plate 61 is suctioned, so that the second suction cup 65 adsorbs the screen to be installed and limits and fixes it.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
