Description

Technical Field

[0001] This invention relates to the field of screen bonding fixture equipment technology, and specifically to an alignment angle spring block fixture for screen bonding. Background Technology

[0002] Screen bonding refers to the process of tightly bonding the various components of a touch screen (such as protective glass, touch layer, and display panel) together using specific technologies. The components of the screen are often vacuum-adsorbed using fixtures during bonding. Before bonding, the components of the screen also need to be aligned to avoid the possibility of misalignment.

[0003] For example, application number 202021707077.X, entitled "Large-size Bonding and Alignment Structure," discloses a large-size bonding and alignment structure, comprising: an upper bonding platform for adsorbing a screen panel; a bonding mechanism, which includes a movable lower bonding plate platform and a polarizer position detection mechanism for detecting the position of the polarizer; the lower bonding plate platform includes a platform base, a bonding plate, and the screen panel position detection mechanism; the bonding plate is located above the platform base and is movably connected to the platform base via a movable module; a polarizer is adsorbed on the bonding plate; and the screen panel position detection mechanism is located on the side of the platform base for detecting the position of the screen panel adsorbed by the upper bonding platform. This utility model provides a large-size bonding and alignment structure with accurate alignment, facilitating subsequent bonding.

[0004] The shortcomings of existing technologies are that the screen may not be accurately aligned before bonding, so adjustments are needed after the screen is placed. For example, the aforementioned patent uses a testing mechanism to detect the position of the screen on the bonding plate and adjusts the position of the bonding plate from different angles through calculation. This involves many steps, and the testing mechanism may also have measurement errors, resulting in low efficiency and unsuitability for large-scale operations. In existing practical operations, some methods also involve setting the moving position of the bonding plate and using tape to fix the alignment angle of the screen to reduce the possibility of screen movement and achieve precise positioning. However, the use of tape may damage the product, which also has certain shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide an alignment angle spring block fixture for screen bonding, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a screen bonding alignment spring block fixture, comprising a bonding table, wherein an upper bonding plate is slidably connected laterally and a lower bonding plate is slidably connected vertically in the bonding table, a positioning block is slidably connected to the top of the lower bonding plate, a return spring is provided between each positioning block and the lower bonding plate, and an alignment block is fixedly connected to each positioning block; a multi-segment toothed plate is fixedly connected in the bonding table, and a sealing ring frame is fixedly connected to the outer side of the lower bonding plate; it also includes a driving assembly, an expansion assembly, and a lifting assembly, all of which are disposed in the lower bonding plate;

[0007] The lower bonding plate moving upward has the following three stations:

[0008] At the first station, when the lower bonding plate moves upward, the drive component meshes with the multi-segment toothed plate, driving the lifting component to move upward and lift the glass screen, which in turn automatically calibrates the position of the glass screen with the alignment block.

[0009] At the second station, the lower bonding plate moves upward again, and the drive component and the multi-segment toothed plate mesh again to drive the lifting component to reset, while driving the expansion component to push the sealing ring frame to expand.

[0010] In the third station, when the lower bonding plate contacts the upper bonding plate, the positioning block moves down to unlock the expansion component, so that the sealing ring frame contracts to wrap and seal the connection between the lower bonding plate and the upper bonding plate.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes a rotating rod rotatably connected to the lower bonding plate. The rotating rod has two reciprocating threaded grooves, and reciprocating threaded blocks are threaded to the outside of the two reciprocating threaded grooves. The rotating rod cylinder is connected to gear one and two gear two respectively through three sets of limiting units.

[0013] As a further description of the above technical solution:

[0014] The limiting component includes a ratchet block 1 that is elastically slidably connected in the rotating rod, and both gear 1 and gear 2 are provided with a ratchet groove 1 that cooperates with the ratchet block 1.

[0015] As a further description of the above technical solution:

[0016] The lifting assembly includes a lifting plate that is vertically slidably connected to the lower bonding plate, and the lifting plate is provided with multiple sets of balls. A connecting frame is fixedly connected to the bottom of the lifting plate, and the connecting frame is rotatably connected to the corresponding reciprocating threaded block through a rotating bar.

[0017] As a further description of the above technical solution:

[0018] The expansion assembly includes two passive toothed plates that are slidably connected in the lower bonding plate, and a connecting plate is fixedly connected between the two passive toothed plates. An L-shaped support rod is fixedly connected to the connecting plate. Multiple sets of track grooves are opened in both passive toothed plates. Multiple L-shaped support rods are slidably connected in the lower bonding plate. Each L-shaped support rod slides in the corresponding track groove through a limiting rod.

[0019] As a further description of the above technical solution:

[0020] The lower bonding plate is also provided with a limiting component, which includes an elastic telescopic rod fixed to the lower bonding plate. One end of the elastic telescopic rod is fixedly connected to a ratchet block, and one side of the passive toothed plate is fixedly connected to a ratchet rack. The elastic telescopic rod forces the ratchet block to engage with the ratchet rack.

[0021] As a further description of the above technical solution:

[0022] Two of the positioning blocks are equipped with unlocking units. The unlocking unit includes a wedge rod one fixedly connected to the positioning plate, and a wedge groove one is opened on the ratchet block two. The wedge rod one contacts the wedge groove one during its movement stroke.

[0023] As a further description of the above technical solution:

[0024] The other two positioning blocks are equipped with auxiliary units. Each auxiliary unit includes a wedge rod two fixedly connected to the positioning block. The passive toothed plate has a wedge groove two. The wedge rod two contacts the wedge groove two during its movement.

[0025] As a further description of the above technical solution:

[0026] The engagement stroke of wedge rod one and wedge groove two takes precedence over the engagement stroke of wedge rod two and wedge groove two.

[0027] As a further description of the above technical solution:

[0028] The upper bonding plate is equipped with a rotating bonding plate, and the top of the lower bonding plate is equipped with a sealing ring.

[0029] In the above technical solution, the alignment angle spring block fixture for screen bonding provided by the present invention has the following beneficial effects:

[0030] This invention utilizes the interplay between a bonding platform, an upper bonding plate, a lower bonding plate, a positioning block, a return spring, an alignment block, a multi-segment toothed plate, a sealing ring frame, a driving assembly, an expansion assembly, and a lifting assembly. Through the movement of the alignment block on the positioning block in conjunction with the lifting assembly, the friction between the lower bonding plates is reduced while automatically preparing the glass screen, minimizing the possibility of glass screen wear. Furthermore, after the alignment block adjusts the screen laterally and comes into contact with the upper bonding plate, it automatically moves into the lower bonding plate, preventing damage to the product during bonding. After adjustment, the lifting assembly separates from the glass screen before the alignment block, simultaneously driving the sealing ring frame to expand. This facilitates sealing the connection between the upper and lower bonding plates during bonding, further improving the sealing performance of the screen. The mutual triggering and coordination between these structures enhances the continuity and accuracy of screen bonding.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0047] Please see Figure 1-10This embodiment provides a screen bonding alignment angle spring block fixture, including a bonding table 1. An upper bonding plate 11 is slidably connected laterally to the bonding table 1, and a lower bonding plate 12 is slidably connected vertically to it. A rotating bonding plate 8 is disposed in the upper bonding plate 11. The upper bonding plate 11, the rotating bonding plate 8 rotating in the upper bonding plate 11, and the lower bonding plate 12 are all moved by an external driving source. A sealing ring 9 is disposed on the top of the lower bonding plate 12 to increase the sealing between the upper bonding plate 11 and the lower bonding plate 12. A positioning block 13 is slidably connected to the top of the lower bonding plate 12. Each positioning block 13 is connected to the lower bonding plate... A return spring 14 is provided between each of the 12, and an alignment block 15 is fixedly connected to each positioning block 13. The alignment block 15 is driven by an external drive source to move on the positioning block 13 so as to adjust the position of the glass screen placed on the lower bonding plate 12, reduce the steps of manual and automatic alignment, and improve the bonding accuracy between the screens. A multi-segment toothed plate 16 is fixedly connected in the bonding table 1. The teeth at both ends of the multi-segment toothed plate 16 are set at different heights on the same side. A sealing ring frame 17 is fixedly connected to the outside of the lower bonding plate 12. It also includes a drive assembly, an expansion assembly, and a lifting assembly, all of which are set in the lower bonding plate 12.

[0048] The lower bonding plate 12 has the following three working stations for moving upward:

[0049] At the first station, when the lower bonding plate 12 moves upward, the drive component engages with the multi-segment toothed plate 16, driving the lifting component to move upward and lift the glass screen. The alignment block 15 automatically calibrates the position of the glass screen. When the alignment block 15 adjusts the position of the glass screen, the lifting component can reduce the friction between the glass screen and the lower bonding plate 12, preventing scratches and damage to the glass screen.

[0050] At the second station, the lower bonding plate 12 moves upward again, and the driving component and the multi-segment toothed plate 16 engage again to drive the lifting component to reset, while driving the expansion component to push the sealing ring frame 17 to expand.

[0051] In the third station, when the lower bonding plate 12 contacts the upper bonding plate 11, the positioning block 13 moves down to unlock the expansion component, so that the sealing ring frame 17 contracts to wrap and seal the connection between the lower bonding plate 12 and the upper bonding plate. By adding the sealing ring frame 17, the sealing performance between the upper bonding plate 11 and the lower bonding plate 12 is further improved, creating a more sealed environment for vacuum adsorption bonding between screens. This device improves the continuity and accuracy of screen bonding through the mutual triggering and cooperation between the various structures.

[0052] In a further embodiment of the present invention, the driving component includes a rotating rod 21 rotatably connected to the lower bonding plate 12. The rotating rod 21 has two reciprocating threaded grooves, and reciprocating threaded blocks 22 are threadedly connected to the outside of the two reciprocating threaded grooves. The rotating rod 21 is connected to a gear 23 and two gears 24 respectively through three sets of limiting units. The limiting component includes a ratchet block 25 elastically slidably connected to the rotating rod 21. Both the gear 23 and the gears 24 are provided with ratchet grooves 26 that cooperate with the ratchet block 25. By setting the limiting component, the gear 23 and the two gears 24 on the rotating rod 21 can be controlled to rotate in one direction.

[0053] Furthermore, the lifting assembly includes a lifting plate 31 that is vertically slidably connected to the lower bonding plate 12, and the lifting plate 31 is provided with multiple sets of ball bearings 32. A connecting frame 33 is fixedly connected to the bottom of the lifting plate 31. The connecting frame 33 is rotatably connected to the corresponding reciprocating threaded block 22 through a rotating bar 34. By providing ball bearings 32 on the lifting plate 31, the friction between the screen and the contact surface can be reduced when the lifting plate 31 lifts the glass screen.

[0054] Furthermore, the expansion assembly includes two passive toothed plates 41 slidably connected in the lower bonding plate 12, and a connecting plate 42 fixedly connected between the two passive toothed plates 41. An L-shaped support rod 43 is fixedly connected to the connecting plate 42. Multiple sets of track grooves 44 are formed in each of the two passive toothed plates 41. Multiple L-shaped support rods 45 are slidably connected in the lower bonding plate 12. Each L-shaped support rod 45 slides in its corresponding track groove 44 via a limiting rod. The track groove 44 is composed of inclined grooves and transverse grooves, so that the multiple L-shaped support rods 45 can move vertically as the passive toothed plates 41 move. The upward movement, combined with the L-shaped support rod 43, allows the sealing ring frame 17 to expand in different directions, enabling the upper bonding plate 11 to perfectly contact and fit with the lower bonding plate 12. The lower bonding plate 12 is also equipped with a limiting component, which includes an elastic telescopic rod 51 fixed on the lower bonding plate 12. One end of the elastic telescopic rod 51 is fixedly connected to a ratchet block 52, and one side of the passive toothed plate 41 is fixedly connected to a ratchet rack 53. The elastic telescopic rod 51 forces the ratchet block to mesh with the ratchet rack 53. By setting the limiting component, the reverse movement direction of the passive toothed plate 41 can be controlled.

[0055] In a further embodiment of the present invention, two positioning blocks 13 are provided with unlocking units, each unlocking unit including a wedge-shaped rod 61 fixedly connected to a positioning plate, and a wedge groove 62 formed on a ratchet block 52, the wedge-shaped rod 61 contacting the wedge groove 62 during its movement; the other two positioning blocks 13 are provided with auxiliary units, each auxiliary unit including a wedge-shaped rod 71 fixedly connected to a positioning block 13, and a wedge groove 72 formed on a passive toothed plate 41, the wedge-shaped rod 71 contacting the wedge groove 72 during its movement; the wedge-shaped rod 61 and The engagement stroke of wedge groove 2 72 takes precedence over the engagement stroke of wedge rod 2 71 and wedge groove 2 72. The downward movement of positioning block 13 drives the unlocking unit to move, triggering the movement of the limiting component to contact the passive toothed plate 41 with the pulling force, so that the pulled sealing ring frame 17 resets to contact the upper bonding plate 11 and the lower bonding plate 12 for sealing, further ensuring the sealing performance during vacuum bonding of the screen. The auxiliary unit is set to further check the sealing performance of the reset and wrapping of the sealing ring frame 17, so the movement stroke of the auxiliary unit lags behind the movement stroke of the unlocking unit.

[0056] Working principle: During operation, the positioning blocks 13, supported by the return springs 14, move upwards, so that the alignment blocks 15 on the positioning blocks 13 are higher than the lower bonding plate 12. At this time, the glass screen to be bonded is placed on the lower bonding plate 12, with the four corners of the glass screen on the four positioning blocks 13. After the external drive source is activated to drive the bonding turntable on the upper bonding plate 11 to rotate, the upper bonding plate 11 moves above the lower bonding plate 12 until the two are on the same line. Then the upper bonding plate 11 stops moving. At this time, the lower bonding plate 12 moves upwards under the drive of the external drive source. When moving upwards, the gear 23 set on the rotating rod 21 will engage a section of the teeth on the multi-segment gear plate 16. When engaged, gear 23 drives the rotating rod 21 to rotate via the limiting component. The rotation of the rotating rod 21 drives the two gears 2 to rotate via the limiting component. The rotation of gears 2 engages with the passive gear plate 41 to move. When the rotating rod 21 rotates, it drives the reciprocating threaded block 22 to move towards each other and approach through the reciprocating threaded groove on it. After approaching, it drives the lifting plate 31 to move upward through the cooperation of the rotating bar 34 and the connecting frame 33, supporting the glass screen placed on the lower bonding plate 12. The glass screen contacts the ball bearings 32 on the lifting plate 31. At this time, when the multiple alignment blocks 15 move to align the glass screen, the friction between the glass screen and the lifting plate 31 is small, and there will be no wear on the glass screen. After the entire process is completed, the lower bonding plate 12 continues to move upward. At this time, gear 1 23 will contact the second segment of teeth on the multi-segment toothed plate 16. The rotating rod 21 will rotate again in the same direction as before, but due to the action of the reciprocating thread groove, it will drive the two reciprocating threaded blocks 22 to move away from each other. With the help of the rotating bar 34 and the connecting frame 33, the lifting plate 31 will move downward and retract into the lower bonding plate 12. At the same time, the passive toothed plate 41 moves under the two rotations of gear 2, driving the L-shaped support rod 1 43 and L-shaped support rod 2 45 to spread out, opening the sealing ring frame 17. At this time, the alignment block 15 on the lower bonding plate 12 will come into contact with the rotating bonding, and push the alignment block 15 and the positioning block 13 to the reset spring. Spring 14 is compressed and moves downward into the interior of the bonding plate 12. During this movement, the wedge rods 61 on the two positioning blocks 13 will enter the wedge grooves 62 in the second ratchet, thereby driving the second ratchet to move and separate from the ratchet rack 53 on the driven gear. The restraining force between the second ratchet and the ratchet rack 53 disappears, the stretched sealing ring frame 17 returns to its original position, and the upper bonding plate 11 and the lower bonding plate 12 come into contact and approach each other, achieving a wrap-around seal. At the same time, the wedge rods 71 ​​on the other two positioning blocks 13 enter the wedge grooves 72 in the driven gear plate 41, further assisting the sealing ring frame 17 to return to its original position and wrap around the plate, thus improving the sealing performance between the upper bonding plate 11 and the lower bonding plate 12 when the screen is bonded.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
