Abstract

This invention discloses a high-precision bonding and alignment device, relating to the field of vehicle-mounted full bonding technology. The invention includes a fixture base, on which a Y-shaped support rod rotatably mounted at its tail end and an L-shaped support rod slidably mounted. A pair of mounting rods parallel to the two top forks of the Y-shaped support rod are slidably mounted on the L-shaped support rod. Support blocks for lifting the CG are provided on the two top forks of the Y-shaped support rod and on the two mounting rods.

Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted full bonding technology, specifically a high-precision bonding and alignment device. Background Technology

[0002] As is widely known, in-vehicle full-fit display technology integrates a high-resolution LCD screen into the vehicle's interior seats. This technology integrates the display into the seat frame and leather, making the entire seat appear seamless, without borders or visible seams, providing a better overall visual effect and a more comfortable driving experience.

[0003] For example, the invention patent with application publication number CN104360500B, application publication date June 22, 2018, entitled "A Processing Method for a Fully Laminated Liquid Crystal Display," describes a fully laminated TFT-LCM module where OCA optical adhesive is first bonded to the surface of the upper polarizer. After pre-baking and degassing under pressure, a fixture is used to align and pre-bond the CTP and TFT-LCM. A bonding machine is then used for pressing, followed by degassing under heat and pressure in a degassing oven to obtain the finished product. Specifically, OCA adhesive is first bonded to the surface of the upper polarizer of the TFT-LCM. Specifically, after OCA bonding, the TFT-LCM undergoes high-temperature and high-pressure degassing. Specifically, after OCA bonding and degassing, the TFT-LCM is aligned and bonded to the CTP. Specifically, a dedicated bonding fixture is used for positioning and bonding when aligning the TFT-LCM with OCA and the CTP. Specifically, after the TFTLCM is bonded to the OCA and aligned with the CTP, it is laminated using a full-lamination press. Then, a degassing oven is used for high-temperature, high-pressure degassing.

[0004] The shortcomings of existing technologies lie in the fact that the key to automotive full lamination lies in the bonding of the CG (glass panel) and LCM. This bonding is mostly carried out in vacuum bonding stations, where the CG and LCM are bonded together using OCA (optical adhesive). However, the relative dimensions of the CG and LCM have relatively high precision control requirements; for example, the XY direction accuracy after assembly is required to be within ±0.2mm. However, individual CG and LCM components also have their own tolerances, such as ±0.05. Traditional bonding alignment fixtures use a gap positioning method, meaning the LCM fixture positioning groove is designed and manufactured with the upper limit of the LCM tolerance plus +0.02 to +0.04, and the CG positioning groove is also its individual tolerance plus +0.02 to +0.04. Therefore, in actual bonding operations, the CPK (copper ketone) often fails to meet standards, and dimensional misalignment (NG) frequently occurs after bonding, leading to product rework and impacting production capacity. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision bonding and alignment device 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 high-precision fitting and alignment device, comprising a fixture base, wherein a Y-shaped support rod rotatably mounted on the tail end and an L-shaped support rod slidably mounted on the fixture base, a pair of mounting rods parallel to the two top branches of the Y-shaped support rod are slidably mounted on the L-shaped support rod, and support blocks for lifting CG are provided on the two top branches of the Y-shaped support rod and on the two mounting rods, wherein:

[0007] The Y-shaped support rod is tilted to move the CG located on it to the bifurcated connection point, and the Y-shaped support rod is rotated to a horizontal state to couple with the mounting rod and move down synchronously.

[0008] As a further description of the above technical solution: both the Y-shaped support rod and the mounting rod are provided with suction cups facing the support block.

[0009] As a further description of the above technical solution: when the Y-shaped support rod is in an inclined state, the suction cups on the Y-shaped support rod are distributed perpendicularly to the Y-shaped support rod.

[0010] As a further description of the above technical solution: the Y-shaped support rod is provided with a convex movable plate corresponding to the suction cup thereon, and the connecting rod on the suction cup is rotatably mounted on the movable plate.

[0011] As a further description of the above technical solution: the Y-shaped support rod moves vertically downward to make the suction cup rotate relative to the movable plate and the movable plate move relative to the Y-shaped support rod.

[0012] As a further description of the above technical solution: the support block moves on the horizontal plane to offset it relative to CG.

[0013] As a further description of the above technical solution: a rotating disk is rotatably arranged in the fixture base, and a transmission rod extending into the rotating disk is provided at the tail end of the Y-shaped support rod.

[0014] As a further description of the above technical solution: both the Y-shaped support rod and the mounting rod are provided with limit strips on their side walls, and the distance between the limit strips and the support block is equal to the thickness of CG.

[0015] As a further description of the above technical solution: a plurality of spring plungers are slidably arranged in the fixture seat, and the L-shaped support rod moves to cause the spring plungers to push the LCM to a predetermined position.

[0016] As a further description of the above technical solution: the L-shaped support rod is provided with a wedge extending into the spring plunger, and the inclined surface of the wedge is inclined in a direction away from the LCM.

[0017] In the above technical solution, the high-precision fitting and alignment device provided by the present invention has the following beneficial effects: During operation, the LCM with OCA on the top is first placed in the groove on the fixture seat, and one side edge of the LCM is tightly attached to a specific side edge of the groove. Then, the CG is placed in the fork of the Y-shaped support rod in an inclined state. The support block on the Y-shaped support rod supports the CG, and the CG slides along the support block on the Y-shaped support rod under the action of gravity, so that the side edge of the CG is tightly attached to the fork connection of the Y-shaped support rod. Then, the Y-shaped support rod rotates with the CG, gradually... The mounting rod is brought into a horizontal position and aligned with the L-shaped support rod. At this point, the mounting rod moves towards the CG under the action of the electric telescopic rod until the mounting rod is close to the side wall of the CG. The support block on the mounting rod is close to the bottom of the CG. The support block on the Y-shaped support rod cooperates with the support block on the mounting rod to lift the CG. The side edge of the CG close to the fork connection of the Y-shaped support rod is aligned with the side edge of the groove on the LCM close to the fixture seat, thus making the CG and LCM aligned. Then, the L-shaped support rod and the Y-shaped support rod move downward under the action of the electric telescopic rod, so that the CG and LCM gradually fit together. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Please see Figure 1-11 This invention provides a technical solution: a high-precision fitting and alignment device fixture base 1 is provided with a Y-shaped support rod 11 rotatably mounted on its tail end and an L-shaped support rod 12 slidably mounted on it. A pair of mounting rods 121 parallel to the two top branches of the Y-shaped support rod 11 are slidably mounted on the L-shaped support rod 12. Support blocks 112 for lifting CG2 are provided on the two top branches of the Y-shaped support rod 11 and on the two mounting rods 121.

[0034] The Y-shaped support rod 11 is tilted so that the CG2 located on it moves to the bifurcated connection. The Y-shaped support rod 11 is rotated to a horizontal state to couple with the mounting rod 121 and move down synchronously.

[0035] Specifically, the fixture seat 1 is located inside the vacuum bonding station. The fixture seat 1 has a groove for positioning the LCM3, and a specific side edge of the groove is directly opposite the bifurcation connection of the Y-shaped support rod 11 in the horizontal state. The side wall of the support block 112 is provided with a ramp. An electric telescopic rod is provided between the L-shaped support rod 12 and the fixture seat 1. An electric telescopic rod is provided between the mounting rod 121 and the L-shaped support rod 12.

[0036] Furthermore, during operation, the LCM3 with the OCA on top is first placed in the groove on the fixture seat 1, with one side edge of the LCM3 closely adhering to a specific side edge of the groove. Next, the CG2 is placed in the fork of the inclined Y-shaped support rod 11. The support block 112 on the Y-shaped support rod 11 supports the CG2, and the CG2 slides along the support block 112 under gravity, causing the side edge of the CG2 to closely adhere to the fork connection of the Y-shaped support rod 11. Then, the Y-shaped support rod 11 rotates with the CG2, gradually becoming horizontal and adhering to the L-shaped support rod 12. At this point, the operator controls the electric telescopic rod. During operation, the mounting rod 121 moves towards CG2 under the action of the electric telescopic rod until the mounting rod 121 is in close contact with the side wall of CG2. The support block 112 on the mounting rod 121 is in close contact with the bottom of CG2. The support block 112 on the Y-shaped support rod 11 cooperates with the support block 112 on the mounting rod 121 to support CG2. The side edge of CG2 is in close contact with the forked connection of the Y-shaped support rod 11 and the side edge of the LCM3 is in close contact with the groove of the fixture seat 1, so that CG2 and LCM3 are aligned. Then, the L-shaped support rod 12 and the Y-shaped support rod 11 move downward under the action of the electric telescopic rod, so that CG2 and LCM3 gradually fit together.

[0037] In another embodiment of the present invention, both the Y-shaped support rod 11 and the mounting rod 121 are provided with suction cups 113 facing the support block 112, and the support block 112 moves on the horizontal plane to offset it relative to CG2.

[0038] Specifically, a tenon is provided above the support block 112, and mortises that match the tenon are provided on the Y-shaped support rod 11 and the mounting rod 121.

[0039] Furthermore, as the Y-shaped support rod 11 and mounting rod 121 move vertically downwards, the suction cups 113 move closer to CG2 and gradually adhere to it, thus fixing CG2 to the Y-shaped support rod 11 and mounting rod 121 via multiple suction cups 113. At this time, the support block 112 can move horizontally with the cooperation of the tenon and mortise, gradually shifting away from CG2 to avoid the support block 112 interfering with the bonding of CG2 and LCM3. When the Y-shaped support rod 11 and mounting rod 121 move CG2 to the predetermined position (where only a narrow gap exists between CG2 and LCM3, and the width of the gap is less than the thickness of CG2), the vacuuming device of the vacuum bonding station is activated to lift CG2. Air is removed from between CG2 and LCM3 to prevent dust in the air from interfering with the bonding between CG2 and LCM3. During this process, the pressure difference between the inside and outside of suction cup 113 decreases, the suction force of suction cup 113 on CG2 decreases, and CG2 is gradually released. Under the action of gravity and the restriction of Y-shaped support rod 11 and mounting rod 121, CG2 falls vertically and bonds with LCM3. The bonding machine inside the vacuum bonding station continues to squeeze CG2, making the connection between CG2 and LCM3 secure. Then, the operator can control the electric telescopic rod to push the mounting rod 121, L-shaped support rod 12 and Y-shaped support rod 11 to move back to the initial state, making it easy for the operator to remove the bonded CG2 and LCM3.

[0040] In another embodiment of the present invention, when the Y-shaped support rod 11 is in an inclined state, the suction cups 113 on the Y-shaped support rod 11 are distributed perpendicularly to the Y-shaped support rod 11.

[0041] Specifically, when the Y-shaped support rod 11 is in an inclined state, the suction cup 113 on the Y-shaped support rod 11 is perpendicular to the Y-shaped support rod 11, so that the top of the Y-shaped support rod 11 is in a fully open state. At this time, it is convenient for the staff to place the CG2 in the fork of the Y-shaped support rod 11. When the Y-shaped support rod rotates to a horizontal state and moves vertically downward, the suction cup 113 rotates relative to the Y-shaped support rod 11, changing from a state perpendicular to the Y-shaped support rod 11 to a state parallel to the CG2, so that the suction cup 113 and the CG2 can be attracted together.

[0042] In another embodiment of the present invention, a convex movable plate 115 corresponding to the suction cup 113 is provided in the Y-shaped support rod 11. The connecting rod 114 on the suction cup 113 is rotatably mounted on the movable plate 115. The Y-shaped support rod 11 moves vertically downward so that the suction cup 113 rotates relative to the movable plate 115 and the movable plate 115 moves relative to the Y-shaped support rod 11.

[0043] Specifically, the suction cup 113 on the Y-shaped support rod 11 has an L-shaped connecting rod 114 at its top, and the connecting rod 114 is rotatably mounted on the corresponding convex movable plate 115. A torsion spring is provided between the connecting rod 114 and the movable plate 115, and a spring is provided between the movable plate 115 and the Y-shaped support rod 11. The Y-shaped support rod 11 has a first slider 116 corresponding to the connecting rod 114 and a second slider 117 corresponding to the support block 112 on the Y-shaped support rod 11. A passage is provided between the first slider 116 and the corresponding connecting rod 114, through which the convex movable plate 114 passes. A first cable 118 is fixed to the middle of the connecting rod 114. A second cable 119 is provided between the second slider 117 and the corresponding support block 112. The side wall of the Y-shaped support rod 11 is provided with corresponding grooves for the first slider 116 and the second slider 117 to move. The fixture seat 1 is provided with a support plate 133 corresponding to the connecting rod 114. The support plate 133 is provided with a notch facing the first slider 116. A sliding plate 134 is slidably arranged in the notch. A spring is provided between the sliding plate 134 and the support plate 133. A spring is provided between the Y-shaped support rod 11 and the support block 112 on it.

[0044] Furthermore, as the Y-shaped support rod 11 moves vertically downwards, the first slider 116 contacts the slide plate 134 on the support plate 133 first, and the slide plate 134 pushes the first slider 116 to move upwards relative to the Y-shaped support rod 11. The first slider 116 pulls the first cable 118, and through the first cable 118, it pulls the connecting rod 114 to rotate relative to the movable plate 115, so that the suction cup 113 changes from a state perpendicular to the Y-shaped support rod 11 to a state parallel to CG2. The first slider 116 continues to move, and through the first cable 118, it continues to pull the connecting rod 114 and the movable plate 115, so that the movable plate 115 and the suction cup 113 move downwards relative to the Y-shaped support rod 11. The suction cup 113 gradually attracts CG2; when the suction cup 113 attracts CG2, the first slider 116 moves to the top of the corresponding groove. The first slider 116 cannot move further upward. The second slider 117 is attached to the top of the support plate 133. The Y-shaped support rod 11 continues to move downward. The first slider 116 pushes the slide plate 134 downward, compressing the spring between the slide plate 134 and the support plate 133. The second slider 117 is pushed by the support plate 133 to move upward relative to the Y-shaped support rod 11. The second slider 117 drives the support block 112 to move horizontally through the second cable 119 and gradually separates from CG2. The spring between the support block 112 and the Y-shaped support rod 11 accumulates elastic potential energy.

[0045] In another embodiment of the present invention, a rotating disk 13 is rotatably disposed in the fixture base 1, and a transmission rod 135 extending into the rotating disk 13 is disposed on the tail end of the Y-shaped support rod 11.

[0046] Specifically, a motor is installed in the fixture base 1, and the rotating disk 13 is fixedly installed on the output end of the motor. A transmission rod 135 is provided between the rotating disk 13 and the tail end of the Y-shaped support rod 11. The transmission rod 135 is specifically an electric telescopic rod.

[0047] Furthermore, during operation, the motor drives the Y-shaped support rod 11 to remain in an inclined state via the rotating disk 13 and the transmission rod 135. At this time, the transmission rod 135 is in its shortest state. Then, the motor drives the Y-shaped support rod 11 to gradually become horizontal, and the transmission rod 135 extends synchronously, so that the Y-shaped support rod 11 and the L-shaped support rod 12 move synchronously in the vertical direction, avoiding the accumulation of bending stress in CG2 due to asynchronous movement of the Y-shaped support rod 11 and the L-shaped support rod 12.

[0048] In another embodiment of the present invention, limit strips 111 are provided on the side walls of both the Y-shaped support rod 11 and the mounting rod 121, and the distance between the limit strip 111 and the support block 112 is equal to the thickness of CG2.

[0049] Specifically, the limiting strip 111 has a notch facing the suction cup 113, which allows the suction cup 113 to be mostly aligned with the support block 112. When the suction cup 113 squeezes the CG2, the support block 112 can share the squeezing force on the CG2 and lift the CG2, thus preventing the CG2 from bending due to local pressure and affecting the overall quality of the CG2.

[0050] Furthermore, the limiting strip 111 can work with the suction cup 113 to restrict CG2, preventing CG2 from rotating relative to the Y-shaped support rod 11 due to the lack of restriction at the top, thereby enabling CG2 to move synchronously with the Y-shaped support rod 11.

[0051] In another embodiment of the present invention, a plurality of spring plungers 131 are slidably disposed in the fixture seat 1, and the L-shaped support rod 12 moves to cause the spring plungers 131 to push the LCM3 to a predetermined position.

[0052] Specifically, a ball bearing 132 is provided at the top of the spring plunger 131, and a spring is provided between the spring plunger 131 and the fixture seat 1. The spring plunger 131 is divided into two groups, and the two groups of spring plungers 131 push against the LCM3 in a direction perpendicular to the L-shaped support rod 12.

[0053] Furthermore, as the L-shaped support rod 12 moves downward, the spring plunger 131 unlocks and moves towards the LCM3 under the action of the spring, so that one side edge of the LCM3 is in close contact with a specific side edge of the groove on the fixture seat 1.

[0054] In another embodiment of the present invention, a wedge 126 extending into the spring plunger 131 is provided on the L-shaped support rod 12, and the inclined surface of the wedge 126 is inclined in a direction away from the LCM3.

[0055] Specifically, a slide rod 122 is slidably disposed in the fixture base 1, a wedge block 126 is fixedly installed on the top of the slide rod 122, a top rod 127 is disposed between the slide rod 122 and the L-shaped support rod 12, the top rod 127 is specifically a self-springing telescopic rod, a third slider 123 is slidably disposed in the fixture base 1 corresponding one-to-one with the suction cups 113 on the L-shaped support rod 12, a spring is disposed between the third slider 123 and the fixture base 1, an extension rod 128 is disposed between the L-shaped support rod 12 and the suction cups 113 on it, and the extension rod 128 is connected to the mounting rod 121. A spring is installed in the vertical direction. The extension rod 128 is a self-springing telescopic rod to accommodate the movement of the mounting rod 121 relative to the L-shaped support rod 12. A third cable 124 is provided between the extension rod 128 and the third slider 123. A fourth cable 125 with a certain redundancy and a certain degree of flexibility (to accommodate the movement of the mounting rod 121 relative to the L-shaped support rod 12, and the difference in the distance of each movement of the mounting rod 121 is the error during CG2 machining) is provided between the support block 112 on the L-shaped support rod 12 and the fixture seat 1.

[0056] Furthermore, as the L-shaped support rod 12 moves downward, it pushes the slide rod 122 downward via the top rod 127. The slide rod 122 then moves the wedge block 126 downward. The inclined surface of the wedge block 126 contacts the spring plunger 131, increasing the movement space of the spring plunger 131. Under the action of the spring, the spring plunger 131 slowly moves closer to the LCM3. The inclined surface of the wedge block 126 prevents the spring plunger 131 from rapidly moving and impacting the side wall of the LCM3, thus protecting the LCM3. At the same time, the distance between the extension rod 128 and the third slider 123 increases, the third cable 124 tightens, and the extension rod 128 is pulled downward. Rod 128 and suction cup 113 move downward relative to L-shaped support rod 12, causing suction cup 113 to gradually adhere to the upper surface of CG2. After adhering, extension rod 128 moves to its limit position, and fourth cable 125 just tightens. L-shaped support rod 12 drives third slider 123 to move downward through third cable 124 and compresses the spring between third slider 123 and fixture seat 1. Fourth cable 125 pulls corresponding support block 112 to move away from CG2 until support block 112 separates from CG2. After the bonding work is completed, L-shaped support rod 12 moves upward, and suction cup 113 and support block 112 gradually return to their original positions.

[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.
