Description

Technical Field

[0001] This invention relates to the field of liquid crystal module technology, and more specifically to a pressure uniform distribution lamination structure for a full lamination equipment for LCM liquid crystal modules. Background Technology

[0002] An LCM is a complete display unit that integrates a liquid crystal display panel, a driver IC, a flexible printed circuit board (FPC), a backlight panel, and related structural components. It can be directly connected to a circuit to achieve image display. The reason for lamination is that the electrode spacing of the liquid crystal panel is only at the micrometer level, which cannot be achieved by traditional welding processes. ACF hot lamination is required to connect the driver IC to the glass substrate and the FPC to the glass substrate. Heating and pressurizing cause the conductive particles in the ACF to form point-to-point conduction between the corresponding electrodes. At the same time, the insulating adhesive layer cures to achieve structural bonding and sealing. This not only ensures the transmission of precise electrical signals but also prevents moisture and dust from entering and damaging the liquid crystal layer and circuits, greatly improving the reliability and service life of the module.

[0003] Referring to a backlight film assembly device with patent number CN222653204U, existing backlight film and LCD module assembly processes suffer from issues such as LCD module displacement, loose bonding, dust adhesion leading to poor adhesion and affecting production quality, and inconvenient disassembly and maintenance of the dust filter plate. Furthermore, this device only uses a single room-temperature rolling roller for pressing, lacking heating softening, pressure holding, and active degassing functions, easily resulting in loose bonding, residual air bubbles, and other defects. It can only complete a single backlight film assembly process, lacking an automatic loading / unloading and material circulation system, leading to low production efficiency. Additionally, the dust removal range is limited to the surface of the rolling roller, failing to fully guarantee the cleanliness of the bonding surface. Therefore, we provide a pressure-uniformly distributed pressing structure for LCM LCD module full lamination equipment to solve the above problems. Summary of the Invention

[0008] The conveying assembly includes a bracket fixedly installed on the side of the frame. A workpiece carrying conveyor belt is provided inside the bracket.

A limit frame is movably connected inside the positioning conveyor slot. A bearing plate is slidably connected inside the limit frame. The bearing plate can apply pressure to the workpiece evenly. A progressive pressure plate is provided on the top surface of the bracket.

[0009] A further improvement of the technical solution of the present invention is that: multiple mounting brackets are fixedly connected to the top surface of the frame, an air inlet chamber is provided inside the frame, and an air outlet chamber is provided at the other end of the frame, and the air inlet chamber and the air outlet chamber are interconnected.

[0010] A further improvement of the technical solution of the present invention is that: a hot air blower is fixedly connected inside the air outlet chamber, the hot air blower is installed in an electric heating box at the input end of the air outlet chamber, and a blower is connected to the input end of the electric heating box.

[0011] A further improvement of the technical solution of the present invention is that: the clamping and releasing conveyor belt and the unloading conveyor belt are stacked inside the frame, and a sufficient gap for the movement of the limiting frame is reserved between the clamping and releasing conveyor belt and the unloading conveyor belt; the electromagnetic magnetic force generator II and the electromagnetic magnetic force generator I are both fixedly connected inside the frame.

[0012] A further improvement of the technical solution of the present invention is that: the output end of the turning conveyor belt is located at one end of the top surface of the unloading conveyor belt and the two do not contact each other; a guide frame is fixedly connected inside the frame, and the guide frame is located on the bottom surface of the clamping and releasing conveyor belt.

[0013] A further improvement of the technical solution of the present invention is that: a guide bucket is fixedly connected to the top surface of the bracket, the guide bucket is set at one end of the top surface of the workpiece carrying conveyor belt, the progressive pressure plate is fixedly connected to the guide bucket, and the progressive pressure plate is fixedly connected to the bottom surface of the mounting frame.

[0014] A further improvement of the technical solution of the present invention is that: the bottom surface of the progressive pressure plate is provided with a guide section with an arc-shaped contact surface, an inclined pressure section, and a pressure holding section parallel to the workpiece carrying conveyor belt from right to left; and an auxiliary heating wire is fixedly connected to one end of the interior of the progressive pressure plate.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention provides a pressure-uniformly distributed pressing structure for a full lamination equipment for LCM liquid crystal modules. By synchronously clamping and conveying the clamping release conveyor belt and the unloading conveyor belt, the conveying stability of the tooling and finished module is ensured throughout the separation process. An independently arranged electromagnetic magnetic force generator is used to adsorb the upper and lower covers of the tooling respectively. With the help of the gravity assistance of the inclined section of the unloading conveyor belt, the upper and lower covers of the tooling are automatically separated without mechanical contact, completely avoiding the scratching and collision damage to the precision tooling and finished module caused by traditional mechanical fork and claw separation mechanisms.

[0019] After separation, the upper cover tooling is automatically transported to the guide frame for recycling via dual conveyor belts. At the same time, the lower cover tooling carrying the finished module is directionally transported to a dedicated unloading section, which facilitates quick material handling by the operator. This achieves fully automated connection of tooling separation, tooling recycling and finished product unloading.

[0020] 2. This invention provides a pressure-uniformly distributed lamination structure for an LCM liquid crystal module full lamination equipment. Precise workpiece positioning and bearing are achieved through a split-type tooling consisting of a "limiting frame-cover plate-bearing plate," and synchronous continuous conveying of the tooling and workpiece is accomplished using a conveyor belt with positioning slots. During the conveying process, an integrated lamination process of "progressive linear pressurization-constant temperature heating for adhesive promotion-pressure holding and rapid cooling curing" is integrated. Throughout the process, the limiting structure ensures uniform pressure and controllable temperature, ensuring that the adhesive fully wets the interface and sets in an ideal state.

[0021] Ultimately, the tooling is automatically separated by dual electromagnetic force generators, the cover plate and the carrier plate are automatically recycled and reused, and the processed workpiece is left in the limiting frame for quick material retrieval. While ensuring bonding quality and processing stability, the continuous and automated production of the hot pressing bonding process and the efficient recycling of tooling are realized.

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1:

[0033] To address the issues of reducing warpage and misalignment rates in products during workpiece pressure application, the following technical solution is proposed: High-temperature heating promotes the expulsion of internal air bubbles and reduces adhesive viscosity during the pressure application process, resulting in more uniform pressure distribution. Rapid cooling and curing after pressure application locks in the bonding position.

[0034] like Figure 1-8 As shown, the present invention provides a pressure uniform distribution pressing structure for a full lamination equipment for LCM liquid crystal modules, including a base unit 1, a conveying component 2 is provided inside the base unit 1, the conveying component 2 is used to convey the target workpiece and gradually apply pressure to it during conveying, and a protective cover 3 is provided on the top surface of the conveying component 2.

[0035] The base unit 1 includes a frame 11, with multiple mounting brackets 16 fixedly connected to the top surface of the frame 11. A hot air blower 111 is installed inside the frame 11, which can control the temperature of the area where the workpiece is located. An air inlet chamber 19 is opened inside the frame 11, and an air outlet chamber 110 is opened at the other end of the frame 11. The air inlet chamber 19 and the air outlet chamber 110 are interconnected. The hot air blower 111 is fixedly connected inside the air outlet chamber 110. The hot air blower 111 is installed in an electric heating box at the input end of the air outlet chamber 110, and a blower is connected to the input end of the electric heating box.

[0036] The hot air blower 111 installed inside the air outlet chamber 110 can drive airflow and increase the airflow temperature. Both the air inlet chamber 19 and the air outlet chamber 110 are located inside the frame 11. The output ends of the air outlet chamber 110 are arranged on both sides of the workpiece inlet end for preheating the workpiece. The air inlet chamber 19 is arranged on both sides near the workpiece output end.

[0037] The hot air blower 111 draws in clean outside air through the air inlet chamber 19 and heats it. The heated airflow is then output to the workpiece surface through the air outlet chamber 110. The high temperature promotes the expulsion of air bubbles inside the workpiece and reduces the viscosity of the adhesive, thereby assisting in the uniform distribution of pressure. When the workpiece after pressure application is transported to the air inlet chamber 19, the airflow generated by the hot air blower 111 can quickly reduce the temperature of the workpiece, allowing it to solidify and set, locking the bonding position, and thus reducing the warping defect rate and bonding position misalignment defect rate of subsequent products.

[0038] Inside the frame 11, a steering conveyor belt 13, a clamping and releasing conveyor belt 12, and a feeding conveyor belt 15 are sequentially arranged along the workpiece transport path. Multiple levers 14 are equidistantly arranged on the surface of the steering conveyor belt 13. When the steering conveyor belt 13 moves, the movement direction of the workpiece is adjusted by the levers 14.

[0039] Electromagnetic magnetic generator 17 and electromagnetic magnetic generator 112 are respectively installed inside the clamping and releasing conveyor belt 12 and the unloading conveyor belt 15. The clamping and releasing conveyor belt 12 and the unloading conveyor belt 15 are stacked inside the frame 11, and a sufficient gap is reserved between the clamping and releasing conveyor belt 12 and the unloading conveyor belt 15 for the movement of the limiting frame 25. Electromagnetic magnetic generator 112 and electromagnetic magnetic generator 17 are both fixedly connected inside the frame 11.

[0040] The top surface of the frame 11 has a groove for the conveyor assembly 2 to move. The mounting bracket 16 is fixed to the top surface of the groove for fixing the progressive pressure plate 26. The top surface of the frame 11 also has a groove for the turning conveyor belt 13 to move.

[0041] The clamping and releasing conveyor belt 12 and the unloading conveyor belt 15 are arranged from top to bottom inside the frame 11, with a guide frame 18 installed between them to collect the cover plate 210 and related components removed by the clamping and releasing conveyor belt 12. Electromagnetic magnetic generator 17 and electromagnetic magnetic generator 112 are respectively installed inside the unloading conveyor belt 15 and the clamping and releasing conveyor belt 12. The magnetic fields generated by the two have opposite polarities and do not interfere with each other, thereby achieving magnetic separation of the upper and lower cover plates.

[0042] The output end of the turning conveyor belt 13 is located at one end of the top surface of the feeding conveyor belt 15 and the two do not contact each other. The guide frame 18 is fixedly connected inside the frame 11 and is located on the bottom surface of the clamping and releasing conveyor belt 12.

[0043] The unloading conveyor belt 15 is internally composed of a horizontal section and an inclined section, with the horizontal section parallel to the clamping and releasing conveyor belt 12. A turning conveyor belt 13 is located at one end of the horizontal section of the workpiece carrying conveyor belt 23 and the unloading conveyor belt 15, and is perpendicular to the angle between them. It is used to transfer workpieces from the top surface of the workpiece carrying conveyor belt 23 to the top surface of the unloading conveyor belt 15. The turning conveyor belt 13 and the workpiece carrying conveyor belt 23 do not interfere with each other during operation.

[0044] In this embodiment, the pressed workpiece is transferred by the turning conveyor belt 13 to the top surface of the unloading conveyor belt 15, and then continues to be conveyed forward by the frame 11. With the cooperation of the clamping and releasing conveyor belt 12 and the unloading conveyor belt 15, the workpiece remains stable during the conveying process;

[0045] At this time, electromagnetic magnetic generator 17 and electromagnetic magnetic generator 112, located inside the clamping and releasing conveyor belt 12 and the unloading conveyor belt 15, respectively adsorb and fix the upper and lower covers of the workpiece. As the workpiece is conveyed to the inclined section of the unloading conveyor belt 15, the upper and lower covers separate under the action of the inclination angle and magnetic force; subsequently, the clamping and releasing conveyor belt 12 continues to convey, collecting the upper cover inside the guide frame 18 for subsequent recycling. The lower cover and the processed module are then conveyed to the unloading section on the top surface of the unloading conveyor belt 15 for quick removal by the operator.

[0046] Example 2:

[0047] like Figure 1-8 As shown, based on Example 1, this invention further solves the technical problems of uneven pressure distribution and unstable temperature control leading to poor bonding quality during the workpiece pressing process in existing equipment, as well as the difficulty in separating the cover plate from the workpiece and the inability to recycle it efficiently.

[0048] The present invention provides a technical solution: Preferably, the conveying component 2 includes a bracket 21 fixedly installed on the side of the frame 11, a workpiece carrying conveyor belt 23 is provided inside the bracket 21, and the top surface of the workpiece carrying conveyor belt 23 is provided with positioning conveying slots 24 for limiting the workpiece at equal intervals. A limiting frame 25 is movably connected inside the positioning conveying slots 24, and a bearing plate 29 is slidably connected inside the limiting frame 25. The bearing plate 29 can apply pressure evenly to the workpiece.

[0049] The top surface of the bracket 21 is provided with a progressive pressure plate 26. The bottom surface of the progressive pressure plate 26 is provided with a guide section with an arc-shaped contact surface, an inclined pressure section, and a pressure holding section parallel to the workpiece carrying conveyor belt 23 from right to left. An auxiliary heating wire 27 is fixedly connected to one end of the progressive pressure plate 26.

[0050] The workpiece carrying conveyor belt 23 is fixedly installed inside the frame 11, and is kept stable by the bracket 21 and the guide bucket 22, and can drive the material to move smoothly. The top surface of the workpiece carrying conveyor belt 23 is evenly provided with multiple positioning conveying slots 24, the size of which is adapted to the limiting frame 25, and is used to fix the position of the limiting frame 25 during transportation;

[0051] The bottom of the progressive pressure plate 26 is sequentially provided with a guide section, a pressure application section, and a pressure holding section, which can gradually apply pressure to the workpiece. An auxiliary heating wire 27 is provided inside the progressive pressure plate 26, and its position corresponds to the guide section and the pressure application section. It is used to maintain the workpiece temperature stably during the pressure application process. In principle, the auxiliary heating softens the material and reduces the flow resistance, thereby improving the uniformity of bonding.

[0052] The limiting frame 25 has four limiting rods 28 fixedly connected inside. The surface of the limiting rods 28 is slidably connected to a bearing plate 29. The bottom surface of the bearing plate 29 is fixedly connected to a shim block 211. The top surface of the limiting frame 25 is movably connected to a cover plate 210. The cover plate 210 is slidably connected to the top of the outer surface of the limiting rods 28. There are two sets of bearing plates 29 and shims 211. Another set of bearing plates 29 and shims 211 is slidably connected to the inside of the bottom surface of the cover plate 210.

[0053] There are two support plates 29 arranged opposite each other, located inside the positioning conveyor slot 24 and the cover plate 210, respectively. The limiting frame 25 is similar in structure to the cover plate 210 but faces opposite directions. The limiting rod 28 fixedly connected inside the limiting frame 25 is used to limit the cover plate 210 and the support plate 29. The shim block 211 fixedly connected to the back of the support plate 29 is made of metal and is used to quickly remove the workpiece in conjunction with the electromagnetic magnetic force generator 17 and the electromagnetic magnetic force generator 212. Its principle is to use the magnetic field to attract the metal shim block to achieve auxiliary separation.

[0054] In this embodiment, by installing the material inside the bearing plate 29 between the limiting frame 25 and the cover plate 210, and limiting the cover plate 210 and the bearing plate 29 by the limiting rod 28, the stability of the workpiece during processing is ensured. The workpiece is put into the guide hopper 22 and is temporarily blocked by the structure at the end of the progressive pressure plate 26. When the positioning conveyor slot 24 inside the workpiece carrying conveyor belt 23 moves to the bottom surface of the limiting frame 25, the limiting frame 25 falls into the positioning conveyor slot 24 and is driven to continuously convey forward;

[0055] During workpiece conveying, the guide section inside the progressive pressure plate 26 first contacts the shim block 211 to achieve initial pressure application; simultaneously, under the limiting action of the limiting rod 28, the stability of the movement of the bearing plate 29 is ensured, ensuring uniform pressure applied to the workpiece. As the workpiece carrying conveyor belt 23 further conveys the workpiece, the pressure application section at the bottom of the progressive pressure plate 26 gradually increases the pressure on the workpiece, while the auxiliary heating wire 27 inside maintains the temperature stability of the workpiece during processing, which is conducive to the full flow of adhesive and filling of the bonding interface. After the workpiece has been pressurized, it is conveyed to the pressure holding section at the bottom of the progressive pressure plate 26. At this time, the workpiece maintains the current pressure state while rapidly reducing its temperature, so that the bonding position is shaped and cured in the current ideal state.

[0056] Subsequently, the limiting frame 25 is conveyed by the workpiece carrying conveyor belt 23 to the top surface of the unloading conveyor belt 15. With the cooperation of the clamping release conveyor belt 12, the unloading conveyor belt 15, and the electromagnetic force generators 17 and 112 installed inside them, the limiting frame 25 quickly separates from the cover plate 210. The cover plate 210 and its internal carrying plate 29 are conveyed into the limiting rod 28 for storage, facilitating subsequent reuse. Simultaneously, the processed workpiece is retained inside the limiting frame 25 and can be quickly removed by the operator.

[0057] The working principle of the pressure uniform distribution pressing structure of the LCM liquid crystal module full lamination equipment is explained in detail below.

[0058] like Figure 1-8 As shown, by installing the material inside the support plate 29 between the limiting frame 25 and the cover plate 210, and limiting the cover plate 210 and the support plate 29 by the limiting rod 28, the stability of the workpiece during processing is ensured. After the workpiece is put into the guide hopper 22, it is temporarily blocked by the end of the progressive pressure plate 26. When the positioning conveyor slot 24 on the workpiece carrying conveyor belt 23 moves to the bottom surface of the limiting frame 25, the limiting frame 25 falls into the slot and is driven to continue forward conveying.

[0059] During the conveying process, the guide section at the bottom of the progressive pressure plate 26 first contacts the raised block 211 to achieve initial pressure application; the limiting rod 28 ensures the stable movement of the bearing plate 29, making the pressure uniform. As the workpiece carrying conveyor belt 23 continues to convey, the pressure in the pressure application section gradually increases, while the auxiliary heating wire 27 maintains a stable processing temperature, promoting the full flow of the adhesive and filling the bonding interface. After the pressure application is completed, the workpiece enters the pressure holding section, where the pressure is maintained and the temperature is rapidly reduced, allowing the bonding position to be shaped and cured in an ideal state.

[0060] Subsequently, the limiting frame 25 is conveyed by the workpiece carrying conveyor belt 23 to the turning conveyor belt 13, and then transferred by the turning conveyor belt 13 to the top surface of the unloading conveyor belt 15, and continues to be conveyed forward by the frame 11. With the cooperation of the clamping and releasing conveyor belt 12 and the unloading conveyor belt 15, the workpiece remains stable;

[0061] At this time, electromagnetic magnetic force generator 17 and electromagnetic magnetic force generator 112, located inside the clamping and releasing conveyor belt 12 and the unloading conveyor belt 15, respectively adsorb and fix the upper and lower covers of the workpiece. When the workpiece is conveyed to the inclined section of the unloading conveyor belt 15, the upper and lower covers separate under the action of the inclined angle and magnetic force. The cover plate 210 and its internal bearing plate 29 are conveyed to the limit rod 28 for storage, which is convenient for subsequent recycling; at the same time, the clamping and releasing conveyor belt 12 collects the upper cover into the guide frame 18, and the lower cover and the processed module are conveyed to the unloading section on the top surface of the unloading conveyor belt 15 for quick removal by the operator;

[0062] By using components such as a progressive pressure plate, auxiliary heating wire, limiting rod, and workpiece carrying conveyor belt, the workpiece is gradually compressed, evenly bonded, and heat-cured during the conveying process. Furthermore, through the coordinated action of components such as a turning conveyor belt, clamping and releasing conveyor belt, unloading conveyor belt, and electromagnetic magnetic force generator, the above effects are further enhanced by achieving automatic separation of upper and lower covers, recycling of cover plates, and rapid unloading of finished products.

[0063] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
