Description

Technical Field

[0001] The invention relates to the technical field of touch screen processing equipment, and specifically discloses a glue dispensing bonding equipment for touch screen bonding. Background Art

[0002] A touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. It has been widely used in various terminal devices such as mobile phones, computers, and car computers. In the assembly process of the touch screen, there is a glue dispensing and bonding process. The specific operation is to first apply glue on the cover plate, and then bond the cover plate and the functional sheet together. At present, due to equipment limitations, this process is divided into two sets of equipment, glue dispensing and bonding, which are carried out in sequence. It not only adds an intermediate transfer process, but also increases the equipment cost.

[0003] The utility model patent with application number CN2010206739029 discloses a vertical touch screen dispensing flip laminating machine, which includes a three-axis motion dispensing system, which is fixed on the main frame, a blower is installed on the top of the main frame, a touch screen controller is installed on the upper right side of the main frame, a dispensing controller is installed on the upper left side of the main frame, a left vacuum adsorption flip laminating mechanism is installed on the main frame and is located below the left side of the three-axis motion dispensing system, and a right vacuum adsorption flip laminating mechanism is installed on the main frame and is located below the right side of the three-axis motion dispensing system. An ejection mechanism is installed below the left vacuum adsorption flip laminating mechanism and the right vacuum adsorption flip laminating mechanism. The dispensing flip laminating machine uses a three-axis motion dispensing system and a dispensing controller to ensure the accuracy of the dispensing position and dispensing amount. After the dispensing is completed, the flip mechanism flips the glass panel that has been glued, and then the upper and lower glass panels are tightly bonded to ensure stable product quality, and realize the two processes of dispensing and bonding of the touch screen. However, during the operation of the vertical touch screen glue dispensing flip laminating machine, the glass panel after glue dispensing needs to be flipped by a flipping mechanism. During the flipping process, the glue will fall off or deviate due to the gravity and centrifugal force of the glue, and the bonding effect of the touch screen cannot be guaranteed. Therefore, in view of the above-mentioned shortcomings of the existing vertical touch screen glue dispensing flip laminating machine, this application designs a new glue dispensing laminating device for the touch screen glue dispensing laminating process, so that it can effectively avoid the shortcomings of the existing equipment.

[0035] A second movable plate 407 is arranged between the two horizontally aligned slide rails 402 below, and a slide port adapted to the slide rails 402 is also provided on the lower surface of the left and right sides of the second movable plate 407. Then a number of guide holes are provided on the second movable plate 407. There are four guide holes in this figure, and they are respectively provided at the four corners of the second movable plate 407. A dispensing jig plate 408 is arranged directly above the second movable plate 407, and a guide slide column 409 corresponding to each guide hole is connected to the lower surface of the second movable plate 407, so that the dispensing jig plate 408 can move up and down relative to the second movable plate 407. At the same time, a positioning groove 410 corresponding to each group of cover plate suction cups 406 is provided on the upper surface of the dispensing jig plate 408, and its display module is placed in the positioning groove 410 during the dispensing process to achieve its precise positioning.

[0036] Arc guide grooves 411 are provided on the inner walls on both sides of the conveying seat 401, and the arc guide grooves 411 are arranged symmetrically and located between the upper and lower slide rails 402. Connecting strips 412 are provided on the left and right sides of the dispensing fixture plate 408, and guide rollers 413 are rotatably connected to the lower end of each connecting strip 412, and the two guide rollers 413 are respectively located in the corresponding arc guide grooves 411. A motor bracket 414 is fixedly provided on an outer side surface of the conveying seat 401, and the motor bracket 414 is located on the mid-vertical line of the arc guide groove 411. A driving motor 415 is installed on the motor bracket 414. When the driving motor 415 is specifically selected, a stepping motor is preferably used, so that its rotation angle can be accurately controlled by controlling the pulse signal input to the stepping motor. A driving gear 416 is connected to the motor shaft of the driving motor 415, and horizontal sliding openings 417 are provided on the sides of the conveying seat 401 above and below the driving gear 416. A first rack 418 and a second rack 419 are provided on the outside of the two horizontal sliding openings 417, which are rotationally symmetrical with the center of the driving gear 416, and the two racks are respectively meshed with the upper and lower ends of the driving gear 416. Finally, the side end of the first moving plate 403 is connected to the first rack 418 through the upper horizontal sliding opening 417, and the side end of the second moving plate 407 is connected to the second rack 419 through the upper horizontal sliding opening 417.

[0037] The touch screen bonding glue dispensing bonding equipment disclosed in this embodiment 1 is used in conjunction with the feeding mechanisms of the display module and the glass cover plate, and the display module feeding mechanism is arranged above the front end of the conveying and bonding mechanism 400, and the glass cover plate feeding mechanism extends into the front lower end of the conveying and bonding mechanism 400.

[0038] During operation, the driving motor 415 is first controlled to rotate in the forward direction, and then the second movable plate 407 is moved toward the front end of the conveying and laminating mechanism 400 under the meshing transmission of the driving gear 416 and the first rack 418 and the second rack 419, while the first movable plate 403 moves toward the rear end of the conveying and laminating mechanism 400 (i.e., in the direction close to the dispensing mechanism). During the movement of the second movable plate 407, the dispensing fixture plate 408 is moved upward under the action of the guide roller 413 and the arc guide groove 411. When the second movable plate 407 moves to the front end, the grabbing and releasing mechanism in the display module feeding mechanism grabs multiple display modules at one time and accurately places them in the corresponding positioning grooves 410.

[0039] Next, the driving motor 415 is controlled to rotate in the opposite direction until the first movable plate 403 moves to the front end, while the second movable plate 407 and the dispensing jig plate 408 move backwards, until the first movable plate 403 moves to the front end, at which time the first movable plate 403 is located directly above the glass cover feeding mechanism, and then the cylinder 405 is started to move the suction cup mounting plate 404 downward, and the glass cover corresponding to each display module is grabbed through multiple sets of cover suction cups 406. At the same time, when the first movable plate 403 moves to the front end, the second movable plate 407 and the dispensing jig plate 408 also move to the rear (i.e., located directly below the dispensing mechanism 300), and then the dispensing mechanism 300 is used to apply glue on the surface of the display module according to the set route.

[0040] After the gluing is completed, the driving motor 415 is controlled to rotate forward again, and when the first movable plate 403 and the second movable plate 407 move to be aligned up and down (that is, located at the mid-perpendicular line of the arc guide groove 411), the rotation is stopped, and then the cylinder 405 is started to push the suction cup mounting plate 404 downward, so that the grasped glass cover plate can be accurately attached to the display module after gluing, thereby achieving accurate attachment between the display module and the glass cover plate.

[0041] Finally, continue to control the driving motor 415 to rotate forward until the second movable plate 407 moves to the front end. At this time, the unloading mechanism grabs the bonded display screen, and then repeats the above-mentioned loading, transportation, gluing and bonding steps to realize continuous operation of the entire equipment. Example

[0042] Example 2 discloses a touch screen bonding device with an improved design based on the technical solution in Example 1, which is mainly aimed at further improving the precise alignment between the glass cover plate and the display module during bonding. The similarities with Example 1 are not described again, and the differences are referred to in the attached Figure 8 and attached Fig. 9 .

[0043] In this embodiment 2, a pressing groove 500 is also provided on the side of the conveying seat 401. The pressing groove 500 is located on the mid-vertical line of the arc guide groove 411. A pressure sensor 501 is provided at the lower end of the pressing groove 500. The pressure sensor 501 is electrically connected to the control module inside the control box 200. A guide pressure rod 502 is provided directly above the pressure sensor 501. The upper end of the guide pressure rod 502 is connected to an induction pressing block 503 extending out of the upper opening of the pressing groove 500. The induction pressing block 503 extends out of the upper end of the pressing groove 500 in an M-shaped design. At the same time, a support spring 504 is provided between the lower surface of the induction pressing block 503 and the bottom of the pressing groove 500, so that the upper end of the induction pressing block 503 extends out of the pressing groove 500 under the action of the support spring 504.

[0044] A connecting block 505 located just above the side of the conveying seat 401 is connected to the middle position of the side end of the first movable plate 403, and a pressing block 506 matching the induction pressing block 503 is connected to the connecting block 505. The pressing block 506 can be set into a V shape according to the upper end structural shape of the induction pressing block 503.

[0045] In the above improved design of the present embodiment 2, after the dispensing is completed, the driving motor 415 rotates forward, and the first moving plate 403 and the second moving plate 407 move in the same direction. When the first moving plate 403 and the second moving plate 407 are about to reach the mid-perpendicular line of the arc guide groove 411, the pressing block 506 will contact the upper end inclined surface of the inductive pressing block 503, and then the inductive pressing block 503 will overcome the effect of the supporting spring 504 and move downward under the action of the extrusion force. At the same time, during the downward movement of the inductive pressing block 503, the guide pressure rod 502 will gradually approach the action surface of the pressure sensor 501. When the pressing block 506 slides over the top of the inductive pressing block 503, the guide pressure rod 502 will act on the pressure sensor 501, and the pressure sensor 501 will transmit the signal to the control box 200, and then the control box 200 will control the driving motor 415 to stop moving.

[0046] Since the second movable plate 407 still has a certain inertia to move after stopping driving, when it moves to the mid-perpendicular line of the arc guide groove 411, the support spring 504 will push out the induction pressing block 503, and the second movable plate 407 is stopped by the engagement between the groove at the center of the induction pressing block 503 and the pressing block 506. After the second movable plate 407 stops, the first movable plate 403 and the second movable plate 407 can be accurately aligned up and down, thereby effectively ensuring the subsequent fitting accuracy between the display module and the glass cover.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
