Description

Technical Field

[0001] The utility model relates to the technical field of laminating jigs, in particular to a jig for auxiliary laminating. Background Art

[0002] like Figure 2 As shown, the existing decorative film bonding device includes a silicone base 10, a silicone middle frame 11, a flexible film pressing member 12, a film positioning member 20, and a glass base 13 which are arranged in sequence from top to bottom. The film is placed in the film positioning member 20, and the part to be bonded 30 is placed on the top of the glass base 13. The silicone base 10 and the glass base 13 are molded together to bond the film to the part to be bonded 30.

[0003] When the existing PET decorative film (film) is attached to the conventional glass cover plate (film-attached part 30), the silicone (flexible film pressing part 12) first contacts the middle plane and then deforms and squeezes under force to gradually transition to the four-sided curved surface. Conventional projects can fully contact and the force is relatively uniform. However, when attaching a crater structure product, the crater position is higher than the plane position of the 3D product, the silicone squeezes the film insufficiently, and the crater position is insufficiently stressed, resulting in bubbles and openings during the attachment. Utility Model Content

[0004] The utility model aims to solve the problem that bubbles and openings are easily generated at the crater position when the film laminating device in the prior art is used, and proposes an auxiliary laminating jig.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A jig for auxiliary lamination includes a silicone base, a silicone middle frame, a flexible film pressing part, a diaphragm positioning part, and a glass base which are arranged in sequence from top to bottom. The diaphragm is located in the diaphragm positioning part, and the part to be laminar is located on the top of the glass base. An upper left clamping hand and an upper right clamping hand are respectively arranged above the two ends of the top of the diaphragm positioning part, and a lower left clamping hand and a lower right clamping hand are respectively arranged below the two ends of the bottom of the diaphragm positioning part. The upper left clamping hand and the upper right clamping hand are respectively detachably fixed to the bottom of the silicone base, and the lower left clamping hand and the lower right clamping hand are respectively detachably fixed to the top of the glass base.

[0007] Preferably, a fixing hole 1 is provided at the bottom of the upper left clamping hand and the upper right clamping hand, and the upper left clamping hand and the upper right clamping hand are detachably fixed to the bottom of the silicone base through the fixing hole 1.

[0008] Preferably, the tops of the lower left clamping hand and the lower right clamping hand are each provided with a second fixing hole, and the lower left clamping hand and the lower right clamping hand are detachably fixed to the bottom of the glass base through the second fixing hole.

[0009] Preferably, the bottom of the flexible film pressing member is provided with a flexible protrusion adapted to the crater of the film-attached member.

[0010] Preferably, the upper left gripper, the upper right gripper, the lower left gripper and the lower right gripper are all made of flexible materials and are contour-designed so that the film-attached piece can be attached and the force is evenly distributed.

[0011] The beneficial effects of the utility model are as follows: in order to solve the problem of large height difference of crater products, the upper left clamp, upper right clamp, lower left clamp and lower right clamp are designed to make the membrane closer to the product shape during lamination, so that the product is evenly stressed during the lamination process, which is convenient for the subsequent production process; the stress points of the original silicone clamp are relatively scattered, and the silicone is squeezed around after being stressed, and the force cannot be effectively output upward, resulting in lamination bubbles. In order to solve this problem, the silicone middle frame and the silicone base are surrounded by edging, so that the silicone cannot be stressed to expand outwards, but can only be pushed up, which effectively improves the bubble problem.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] The technical solution of this application is applied to all crater lamination processes. By improving the machine's pulling and profiling method, the film is made more similar to the product shape before lamination, reducing abnormal problems after lamination. By redesigning the machine's gripper, the machine can meet the lamination requirements of products of different shapes without changing the original structure of the machine, reducing equipment costs and modification time.

[0017] Reference Figure 1-2A jig for auxiliary lamination includes a silicone base 10, a silicone middle frame 11, a flexible film pressing member 12, a diaphragm positioning member 20, and a glass base 13 which are arranged in sequence from top to bottom. The diaphragm is located in the diaphragm positioning member 20, and a film-attached member 30 is located on the top of the glass base 13. An upper left clamping hand 40 and an upper right clamping hand 41 are respectively arranged above the two ends of the top of the diaphragm positioning member 20, and a lower left clamping hand 50 and a lower right clamping hand 51 are respectively arranged below the two ends of the bottom of the diaphragm positioning member 20. The upper left clamping hand 40 and the upper right clamping hand 41 are respectively detachably fixed to the bottom of the silicone base 10, and the lower left clamping hand 50 and the lower right clamping hand 51 are respectively detachably fixed to the top of the glass base 13. The upper left clamping hand 40 and the upper right clamping hand 51 are respectively detachably fixed to the bottom of the silicone base 10. A fixing hole 1 is provided at the bottom of the clamping hand 41, and the upper left clamping hand 40 and the upper right clamping hand 41 are detachably fixed to the bottom of the silicone base 10 through the fixing hole 1. A fixing hole 2 is provided at the top of the lower left clamping hand 50 and the lower right clamping hand 51, and the lower left clamping hand 50 and the lower right clamping hand 51 are detachably fixed to the bottom of the glass base 13 through the fixing hole 2. A flexible protrusion adapted to the crater of the piece to be filmed 30 is provided at the bottom of the flexible film pressing part 12. The upper left clamping hand 40, the upper right clamping hand 41, the lower left clamping hand 50 and the lower right clamping hand 51 are all made of flexible material and are all contoured designs. They are designed according to the specific shape of the piece to be filmed 30 so that the piece to be filmed 30 can be fitted and subjected to uniform force. Their specific shapes will not be repeated here.

[0018] Working principle: Step 1: Incoming cover plate (glass, plastic, synthetic material) (film-to-be-laminated part 30), incoming film imported substrate and optical adhesive film material (leather grain, leather, PU, ​​TPU), etc., pass IQC incoming appearance inspection, and are sent to the laboratory for relevant reliability performance testing, and the layers are confirmed whether the incoming materials meet the environmental protection test requirements and functional test requirements;

[0019] Step 2: Select imported substrates and optical adhesive film materials with good softness, and press the large sheets of the incoming film and OCA adhesive together through roller equipment to serve as the bonding medium between the leather grain and the 3D cover. In addition, after the large sheets are pasted together, post-process degassing (45 degrees / 10Kg / 20Min) is required, and FQC confirms the appearance inspection to avoid abnormalities such as bubbles / indentations;

[0020] Step 3: Design the laser fixture through programming. First, take a photo of the incoming large film through CCD recognition according to the drawing, and then laser it into the size of the fitting area;

[0021] Step 4: Use a roller machine to attach the laser-printed film to the guide film;

[0022] Step 5: Use the profiling grippers (upper left gripper 40, upper right gripper 41, lower left gripper 50 and lower right gripper 51) to clamp the film that has been bonded to the guide film on the lower cavity silicone profiling fixture to ensure that the film is within the camera CCD camera range. It is important to return the machine to the origin first, calibrate the position of the X, Y and Q axes in three directions, manually adjust the platform for position correction (progress compensation), and ensure that the camera shooting position is within the visible area, otherwise it will affect the final bonding deviation and precision stability effect.

[0023] Step 6: Place the 3D cover with the concave surface facing up and flatly on the upper concave fixture. Make sure to start the clamping device after it is in place. Press the vacuum button to firmly adsorb the product on the fixture. Make sure the camera position is within the visible area, otherwise it will affect the final fitting deviation effect.

[0024] Step 7: Open the running system in the display area of ​​the device, create a target grabbing vision template (create 2 target grabbing templates (round hole, straight edge) for the right cavity 3D cover and the left cavity diaphragm respectively), calibrate the position of the CCD camera by the product size and read the recorded data. Each project has a unique CCD target grabbing template. The CCD alignment system will grab the position information of the 3D glass cover or plastic cover and diaphragm, and generate a compensation coordinate system. After recording the cover plate reference information by taking a photo of the left cavity and comparing it with the coordinate information of the right cavity diaphragm, the motor compensation platform in the three directions of X, Y, and Q of the right cavity will automatically perform position compensation. If the compensation is not in place, the corresponding compensation values ​​of the X, Y, and Q directions need to be input according to the measured values ​​for compensation correction.

[0025] Step 8: After the upper and lower cavities are loaded, the right cavity CCD takes a picture to complete the position compensation of the X, Y, Q motor compensation platform, and the right cavity flips 180° through the central flip axis to enter the set pre-bonding position and contact with the left cavity sealing ring. The buckles on both sides lock the left and right cavities to prevent air leakage. (At this time, the 3D cover and the diaphragm are not in contact at the pre-bonding position)

[0026] Step 9: In this process, the upper and lower chambers are closed to form a closed space. The system signal is transmitted to the hydraulic vacuum pump, and the exhaust pipe is started to evacuate for 3 seconds to create a vacuum environment. When the air pressure reaches the set value of -100kp, the Z-axis silicone of the lower chamber fixture slowly moves upward under the drive of the servo motor. The silicone is deformed and expanded by force, first contacting the plane in the middle and then gradually changing to the two sides or four sides of the curved surface. In this process, the 3D single or double-curved cover plate is bonded to the membrane material in a dead-angle extrusion method, forming a high-end luxury visual effect of fitting various materials.

[0027] After the set bonding time of 6S, the entire bonding operation is completed, the vacuum and deflation of the cavity are automatically completed, the lock is automatically opened, the flip axis flips and each component automatically returns to the standby position, and the product can be taken out and sent to the degassing process for degassing to confirm the first piece. After IPQC measures the bonding accuracy and the inspection table confirms the appearance, if there is no abnormality, the first piece will be signed to notify normal operation. If the measurement accuracy and appearance are unqualified, the accuracy must be compensated and the appearance must be adjusted again until the requirements are met.

[0028] Step 10: After the product is pasted, the guide film is removed by UV light, and then sent to the degassing furnace for degassing.

[0029] Main parameters:

[0030] Lamination parameters: 19KG lamination time 6S

[0031] Defoaming parameters: 16kg, 45 degrees, 15min.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
