Description

Technical Field

[0001] The present invention belongs to the field of touch display production, and particularly relates to a water glue frame pasting device for touch displays. Background Art

[0002] Touch displays are widely used in smart phones, tablet computers, vehicle central controls, industrial control panels, medical devices, etc. Their production requires high-precision bonding processes to ensure touch sensitivity, display effects, and durability; the water glue frame pasting device for touch displays is a special device for pasting touch screens and display screens through water glue. Its working principle is mainly to precisely control the application amount and position of the water glue so that the touch screen and the display screen can be seamlessly bonded together; this bonding method can effectively isolate dust and moisture, improving the display effect and service life.

[0003] Before bonding the touch screen and the display screen, in order to ensure the quality of the bonded product, it is necessary to ensure the high cleanliness of the bonding surfaces of the two. For this purpose, a water glue frame pasting device for touch displays is proposed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a water glue frame pasting device for touch displays, which solves the problems in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The water glue frame pasting device for touch displays includes a workbench. A positioning groove is opened at the upper end of the workbench to position and install the touch screen; a slidable mounting frame is arranged on the workbench, a liftable connecting plate is arranged on the mounting frame, a plurality of suction pipes are arranged on the connecting plate, and suction nozzles are arranged on the suction pipes to adsorb the display screen.

[0007] A slidable slider is arranged on the workbench, and the sliding direction of the slider is perpendicular to the sliding direction of the mounting frame; a mounting plate is fixed at the upper end of the slider, and a first blowing pipe and a second blowing pipe are respectively arranged on both sides of the mounting plate. When the mounting frame is at the end far from the touch screen, the first blowing pipe and the second blowing pipe respectively aim at the display screen and the touch screen, so as to be able to blow air to fully remove dust from their contact surfaces.

[0008] Furthermore, an adsorption assembly is arranged at the lower end of the workbench. The adsorption assembly includes a support frame fixed at the lower end of the workbench. A plurality of air pipes are fixed on the support frame. A plurality of through holes are opened in the positioning groove. The through holes correspond to and cooperate with the air pipes one by one. The upper end surface of the air pipe is not higher than the inner bottom surface of the positioning groove. The air pipe is connected to a blowing and suction dual-purpose air pump.

[0009] Further, the slider is slidably connected to the workbench, and the sliding direction is perpendicular to the sliding direction of the mounting bracket. Two second fixing plates are fixed to the lower end of the workbench. A rotatable second lead screw is arranged between the two second fixing plates. The second lead screw passes through the slider and is threadedly connected thereto.

[0010] Further, the lead angle of the second lead screw is less than the equivalent friction angle.

[0011] Further, the mounting bracket is slidably connected to the workbench. Two first fixing plates are fixed to the upper end of the workbench. A rotatable first lead screw is arranged between the two first fixing plates. The first lead screw passes through the mounting bracket and is threadedly connected thereto.

[0012] Further, the lead angle of the first lead screw is less than the equivalent friction angle.

[0013] Further, a limiting component is arranged at the upper end of the workbench. The limiting component includes a gear fixed to the end of the first lead screw. A third fixing plate is fixed to the upper end of the workbench. A sliding rod is slidably connected to the third fixing plate. A clamping block is arranged at one end of the sliding rod. A spring is sleeved on the sliding rod. Two ends of the spring are respectively fixed to the third fixing plate and the clamping block. Under the elastic force of the spring, the clamping block can be engaged between two adjacent teeth of the gear.

[0014] Further, a connecting rod is fixed to the end of the sliding rod away from the clamping block. A trigger rod is fixed to one side of the mounting plate; during the dust removal process, the mounting plate moves closer to the mounting bracket, so that the trigger rod can touch the connecting rod and drive the clamping block away from the gear;

[0015] When the mounting plate reaches the closest point to the mounting bracket, both the display screen and the touch screen are completely dusted. At this time, the clamping block just leaves the gear.

[0016] Advantages of the present invention:

[0017] 1. By fitting and installing the touch screen in the positioning groove, and arranging a fitting component to adsorb the display screen, while driving the display screen to move and lift, and cooperating with the water glue, the fitting of the touch screen and the display screen can be realized; by arranging a dust blowing component, a slidable mounting plate is arranged in the dust blowing component, and a first air blowing pipe and a second air blowing pipe are respectively arranged on both sides of the mounting plate to respectively align with the display screen and the touch screen, so as to blow air to the contact surfaces of the two to fully remove dust.

[0018] 2. By arranging a limiting component on the workbench to control the sliding timing of the mounting bracket, it is avoided that during the dust removal operation, due to misoperation, the first lead screw rotates, causing the mounting bracket to slide, resulting in the first air blowing pipe not being able to align with the display screen, thereby affecting the dust removal effect.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] As Figure 1 and Figure 2 shown, the water glue frame pasting device for a touch display screen includes a workbench 1. A positioning groove 11 is opened at the upper end of the workbench 1. A touch screen 2 is placed in the positioning groove 11 in a matching manner. When the touch screen 2 is placed in the positioning groove 11, the upper surface of the touch screen 2 protrudes from the upper end surface of the workbench 1. Then, by applying water glue on the surface of the touch screen and setting a laminating component 4 at the upper end of the workbench 1, the display screen and the touch screen are pasted together with water glue to obtain a touch display screen;

[0029] In this embodiment, in order to prevent the touch screen from detaching from the positioning groove 11 during dust blowing or glue application, an adsorption component 3 is provided at the lower end of the workbench 1 to adsorb the touch screen in the positioning groove 11 and be able to blow the touch screen away from the positioning groove 11 after lamination is completed, facilitating taking;

[0030] As Figure 2 and Figure 3 shown, the adsorption assembly 3 includes a support frame 31 fixed to the lower end of the workbench 1. A plurality of air pipes 32 are fixed on the support frame 31. A plurality of through holes 12 are formed in the positioning groove 11. The through holes 12 correspond to and cooperate with the air pipes 32 one by one, and the upper end surface of the air pipe 32 is not higher than the inner bottom surface of the positioning groove 11. By connecting the air pipe 32 to an air pump, it is possible to generate an adsorption force to adsorb the touch screen in the positioning groove 11;

[0031] When the touch screen and the display screen are attached, the air pump (a two-way air pump for blowing and sucking) blows air to lift the touch display screen in the positioning groove 11, and by controlling the blowing pressure, it is possible to prevent the touch display screen from being blown away by excessive blowing force, thereby achieving the purpose of convenient taking.

[0032] As Figure 4 shown, the attachment assembly 4 includes a mounting frame 41 that can slide on the upper end of the workbench 1. A cylinder 42 is provided on the mounting frame 41. A connecting plate 43 is fixed to the end of the driving shaft of the cylinder 42. A plurality of suction pipes 44 are installed on the connecting plate 43. The lower end of the suction pipe 44 is connected to a suction nozzle 45. The suction pipe 44 is connected to a suction pump. Under the action of the suction pump, the lower end of the suction nozzle 45 adsorbs the display screen 46; by controlling the sliding of the mounting frame 41, the display screen 46 can reach directly above the touch screen 2, and then under the drive of the cylinder 42, the attachment of the display screen 46 and the touch screen 2 can be realized;

[0033] A driving assembly 5 is provided on the upper end of the workbench 1 to drive the sliding of the mounting frame 41. The mounting frame 41 is slidably connected to the workbench 1. As Figure 5 shown, the driving assembly 5 includes two first fixing plates 51 fixed to the upper end of the mounting frame 41. A first lead screw 52 is rotatably connected between the two first fixing plates 51. The first lead screw 52 passes through the mounting frame 41 and is threadedly connected thereto. By providing a motor on one of the first fixing plates 51 to drive the rotation of the first lead screw 52, the driving of the sliding of the mounting frame 41 can be realized;

[0034] Moreover, in order to ensure the stability of the mounting frame 41 after position adjustment, the first lead screw 52 needs to have self-locking property, that is, the thread lead angle of the first lead screw 52 is smaller than the equivalent friction angle;

[0035] Of course, the method of driving the sliding adjustment of the mounting frame 41 includes but is not limited to the structure of the first lead screw 52 in this embodiment. In some embodiments, the mounting frame 41 can also be directly driven to slide by providing a cylinder, a telescopic rod and other linear driving components on the upper end of the workbench 1.

[0036] A dust blowing assembly 6 is provided on the upper end of the workbench 1. The dust blowing assembly 6 can simultaneously blow air to remove dust from the contact surfaces of the touch screen 2 and the display screen 46 to ensure the attachment quality;

[0037] As shown Figure 6 in FIG. 2, the dust blowing assembly 6 includes a slidable slider 61, and the sliding direction of the slider 61 is perpendicular to the sliding direction of the mounting bracket 41; a mounting plate 62 is fixed to the upper end of the slider 61, and a first air blowing pipe 63 and a second air blowing pipe 64 connected to the air blowing pump are respectively arranged on both sides of the mounting plate 62. When the mounting bracket 41 is located at the end far from the touch screen 2, the first air blowing pipe 63 and the second air blowing pipe 64 can respectively align with the display screen 46 and the touch screen 2, and blow air to remove dust from the contact surfaces of the two; as the slider 61 slides, the sufficiency of dust removal from the touch screen 2 and the display screen 46 can be improved;

[0038] In this embodiment, the slider 61 is slidably connected to the workbench 1, and the sliding direction is perpendicular to the sliding direction of the mounting bracket 41. Two second fixing plates 65 are fixed to the lower end of the workbench 1, and a second lead screw 66 is rotatably connected between the two second fixing plates 65. The second lead screw 66 passes through the slider 61 and is threadedly connected thereto. By arranging a motor on one of the second fixing plates 65 to drive the second lead screw 66 to rotate, the driving of the slider 61 to slide can be realized; and the second lead screw 66 also has self-locking (the thread lead angle of the second lead screw 66 is less than the equivalent friction angle), so that the position of the slider 61 remains stable after adjustment;

[0039] Of course, the way to drive the slider 61 to slide includes but is not limited to the structure of the second lead screw 66 in this embodiment. In some embodiments, the slider 61 can also be directly driven to slide by arranging linear driving components such as cylinders and telescopic rods on the workbench 1.

[0040] It is worth mentioning that when blowing dust to remove dust, it is necessary to ensure that the mounting bracket 61 is in the initial position (the farthest end point from the touch screen 2) so that the first air blowing pipe 63 can align with the display screen 46; for this reason, in this embodiment, a limiting component 7 is arranged on the workbench 1 to limit the position of the mounting bracket 61, so that before the dust removal work is completed, the position of the mounting bracket 61 is locked, thereby avoiding the mounting bracket 61 leaving from the initial position before the dust removal component 6 completes the dust removal work, resulting in the first air blowing pipe 63 being unable to align with the display screen 46, thus affecting the dust removal effect on the display screen 46;

[0041] As shown Figure 7As shown in the figure, the limiting component 7 includes a gear 71 fixed to the end of the first lead screw 51. A third fixing plate 72 is fixed to the upper end of the workbench 1. A sliding rod 73 is slidably connected to the third fixing plate 72. A clamping block 74 is provided at one end of the sliding rod 73. A spring 75 is sleeved on the sliding rod 73. The two ends of the spring 75 are respectively fixedly connected to the third fixing plate 72 and the clamping block 74. Under the elastic force of the spring 75, the clamping block 74 can be engaged between two adjacent teeth of the gear 71, so as to limit the sliding of the first lead screw 51, so as to lock the mounting bracket 61 at the farthest end point from the touch screen 2, so as to ensure that the first air blowing pipe 63 can be aligned with the display screen 46 for dust blowing;

[0042] A connecting rod 76 is fixed to the end of the sliding rod 73 away from the clamping block 74. A trigger rod 8 is fixed to one side of the mounting plate 62; during the dust removal process, the mounting plate 62 moves closer to the mounting bracket 41, so that the trigger rod 8 can touch the connecting rod 76 and drive the clamping block 74 away from the gear 71; and when the mounting plate 62 reaches the closest point to the mounting bracket 41, both the display screen 46 and the touch screen 2 are completely dusted. At this time, the clamping block 74 just leaves the gear 71 to release the sliding freedom of the mounting bracket 41; thus, the control of the sliding timing of the mounting bracket 41 is realized, and during the dust removal operation, the first lead screw 51 is prevented from rotating due to misoperation, so that the mounting bracket 41 slides, resulting in the first air blowing pipe 63 being unable to be aligned with the display screen 46, thereby affecting the dust removal effect.

[0043] Working principle:

[0044] By fitting and installing the touch screen 2 in the positioning groove 11 and setting the fitting component 4 to adsorb the display screen 46, and driving the display screen 46 to move and lift at the same time, the touch screen 2 and the display screen 46 can be fitted with the water glue; by setting the dust blowing component 6, a slidable mounting plate 62 is arranged in the dust blowing component 6, and a first air blowing pipe 63 and a second air blowing pipe 64 are respectively arranged on both sides of the mounting plate 62 to be respectively aligned with the display screen 46 and the touch screen 2 to blow air on the contact surfaces of the two for sufficient dust removal. By setting the limiting component 7 on the workbench, the control of the sliding timing of the mounting bracket 41 is realized, and during the dust removal operation, the first lead screw 51 is prevented from rotating due to misoperation, so that the mounting bracket 41 slides, resulting in the first air blowing pipe 63 being unable to be aligned with the display screen 46, thereby affecting the dust removal effect.
