Description

Technical Field

[0001] This application relates to the field of FPC alignment and preloading technology, and in particular to a universal positioning auxiliary fixture for rapid FPC alignment and preloading. Background Technology

[0002] A universal positioning auxiliary fixture is a tool used to improve production efficiency and processing accuracy. It is widely used in the fields of electronics, machining, and semiconductors. It is widely used in the production process of LCD modules. It is used to align and pre-press the FPC with the LCD glass substrate and then to press and cure the FPC. In the alignment and pre-pressing operation between the FPC and the LCD glass substrate, a pre-pressing machine is used to melt, bond, and cure the ACF, so that the FPC and the LCD glass substrate are bonded together.

[0003] A universal positioning auxiliary fixture for rapid alignment and pre-pressing of FPC, as mentioned in an existing Chinese patent (authorization announcement number: CN218788123U), includes an operating platform with a feeding section. The feeding section has uniformly arranged suction holes for holding the liquid crystal glass substrate. A baffle structure for restricting the liquid crystal glass substrate is located at a corner of the feeding section on the operating platform. A flip-up cover plate is also positioned and installed on the operating platform. This fixture can position both the FPC and the liquid crystal glass substrate on the operating platform during the bonding operation, ensuring accurate alignment of the connection position between the FPC and the liquid crystal glass substrate, and placing them directly below the pre-pressing head of the pre-pressing machine. By simply operating the cover plate, the stacked positioning of the FPC and the liquid crystal glass substrate can be achieved. After pre-pressing, the cover plate can be slightly opened, and the bonded liquid crystal module can be pulled out in a direction away from the cover plate.

[0004] When using the aforementioned positioning auxiliary fixture, the operator needs to place the FPC and the LCD glass substrate onto the mounting plate in sequence. The FPC is then moved and aligned manually and visually using the baffle. This movement and alignment is time-consuming, and during manual alignment, the operator's skill level can affect the alignment accuracy of the FPC, which can lead to deviations and thus affect product quality and processing efficiency. Utility Model Content

[0005] The purpose of this application is to address the problem that when using the aforementioned positioning auxiliary fixture, workers need to place the FPC and the liquid crystal glass substrate sequentially onto the mounting plate, and then manually and visually move and align the FPC using the help of baffles. This movement and alignment is time-consuming, and during manual alignment, the alignment accuracy of the FPC is easily affected by factors such as the worker's skill level, which can lead to deviations and thus affect product quality and processing efficiency. This application provides a universal positioning auxiliary fixture for rapid alignment and pre-pressing of FPC.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A universal positioning auxiliary fixture for rapid alignment and pre-compression of FPC includes a cabinet. A fixing frame is fixed on one side of the cabinet, and a mounting plate is fixed on the cabinet. The fixing frame corresponds to the mounting plate. Vacuum suction holes are installed on the mounting plate in an array. An electric track is fixed on the fixing frame. An electric telescopic rod is provided at the lower end of the fixing frame. Pneumatic suction cups are provided at the lower end of the electric telescopic rod in an array. Four symmetrical limiting strips are provided on the mounting plate. Motors are fixed on the sides and ends of the mounting plate. A limiting mechanism is provided between the motors and the mounting plate.

[0007] By adopting the above technical solution and using the limiting mechanism, it is easy to accurately align the FPC with the liquid crystal glass substrate, reduce the deviation during FPC alignment, improve the processing efficiency and quality of the auxiliary fixture, and facilitate the processing of FPC.

[0008] Furthermore, the limiting mechanism includes a bidirectional screw fixed to the motor output end, the motor output end extending into the mounting plate, and two symmetrical limiting rods threaded onto the bidirectional screw. The limiting rods extend out of the mounting plate and are fixedly connected to the limiting strip, and a limiting component is provided between the limiting rods and the motor.

[0009] By adopting the above technical solution, the rotation of the motor drives the bidirectional screw to rotate, the rotation of the bidirectional screw drives the limiting rod to move, and the limiting rod drives the limiting strip to move relative to each other, which facilitates the restriction of the liquid crystal glass substrate and facilitates the positioning of the FCP.

[0010] Furthermore, the limiting component includes a limiting post fixed within the mounting plate, the limiting post being slidably disposed with the limiting rod, the limiting post penetrating the limiting rod, a movable plate being fixed to the telescopic end of the electric telescopic rod, and a limiting element being disposed between the movable plate and the mounting plate.

[0011] By adopting the above technical solution, the limiting rod slides on the limiting post to restrict the limiting rod and facilitate the movement of the limiting strip.

[0012] Furthermore, the limiting component includes a controller fixed to the cabinet, and positioning sensors are fixed to both the mounting plate and the movable plate. The movable plate is fixedly connected to the pneumatic suction cup.

[0013] By adopting the above technical solution, the positioning sensor on the mobile board and the positioning sensor on the mounting board can sense each other, which facilitates the accurate positioning of FCP.

[0014] Furthermore, the two bidirectional screws at the output ends of the motors are arranged in a cross shape.

[0015] By adopting the above technical solution, the bidirectional screws are arranged in a cross shape, which facilitates the movement of the limiting strip to restrict the liquid crystal glass substrate from four directions, thereby improving the limiting effect and reducing displacement.

[0016] Furthermore, a pressure sensor is fixed to one side of the limiting strip, and a limiting plate is fixed to the end of the pressure sensor away from the limiting strip. The pressure sensor is electrically connected to the controller.

[0017] By adopting the above technical solution, the pressure sensor detects the limiting pressure, reducing the possibility of damage to the liquid crystal glass substrate due to compression.

[0018] Furthermore, a pad is fixed on the limiting plate, and the pad is an elastic rubber pad.

[0019] By adopting the above technical solution, the pad is an elastic rubber pad, which facilitates the restriction and protection of the liquid crystal glass substrate.

[0020] Furthermore, an electric track two is fixed to the lower end of the electric track one, and the electric track one and the electric track two are arranged in a cross shape. The lower end of the electric track two is fixedly connected to the electric telescopic rod.

[0021] By adopting the above technical solution, the electric track one and electric track two are in a cross shape, which makes it easy for the pneumatic suction cup to drive the FPC to move and facilitates precise positioning.

[0022] In summary, this application includes at least one of the following beneficial effects: 1. When using the auxiliary fixture, start the motor. The motor rotation drives the bidirectional screw to rotate, which in turn moves the limiting rod. The limiting rod then moves the limiting bar relative to the limiting rod, causing it to slide on the limiting post to restrict the placement of the liquid crystal glass substrate. This restriction is further strengthened by the pneumatic suction cup, reducing the substrate's movement. Then, the positioning sensors on the moving plate and the mounting plate sense each other. Through the controller, precise alignment between the FPC and the liquid crystal glass substrate is achieved. The electric telescopic rod extends and retracts, driving the pneumatic suction cup to bring the FPC and the liquid crystal glass substrate into contact, reducing positioning deviations. This limiting mechanism facilitates precise alignment between the FPC and the liquid crystal glass substrate, minimizing alignment errors and improving the processing efficiency and quality of the auxiliary fixture, thus facilitating FPC processing.

[0023] 2. When the auxiliary fixture is used, the pressure sensor detects the limiting pressure when the limiting bar restricts the FPC. When the detected pressure exceeds the set value, it feeds back to the controller, which controls the motor to stop, reducing the possibility of damage to the LCD glass substrate by squeezing. The pad is an elastic rubber pad, which increases the friction with the LCD glass substrate, making it easier to restrict and protect the LCD glass substrate. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a universal positioning auxiliary fixture for rapid alignment and pre-compression of FPC.

[0031] Reference Figure 1 and Figure 2 A universal positioning auxiliary fixture for rapid alignment and pre-compression of FPC includes a cabinet 1, a fixing frame 2 fixed on one side of the cabinet 1, a mounting plate 3 fixed on the cabinet 1, the fixing frame 2 corresponding to the mounting plate 3, vacuum suction holes 4 installed on the mounting plate 3 in an array, an electric track 6 fixed on the fixing frame 2, an electric telescopic rod 8 provided at the lower end of the fixing frame 2, a pneumatic suction cup 10 provided at the lower end of the electric telescopic rod 8 in an array, four symmetrical limiting strips 5 provided on the mounting plate 3, a motor 11 fixed on the side and end of the mounting plate 3, and a limiting mechanism provided between the motor 11 and the mounting plate 3.

[0032] When using the auxiliary fixture, the electric telescopic rod 8 is activated. The electric telescopic rod 8 extends and retracts, driving the pneumatic suction cup 10 to move. The pneumatic suction cup 10 adsorbs and moves the FPC and liquid crystal glass substrate to be installed. During installation, the limiting mechanism facilitates the precise alignment of the FPC and the liquid crystal glass substrate, reduces the deviation during FPC alignment, improves the processing efficiency and quality of the auxiliary fixture, and facilitates the processing of FPC.

[0033] Reference Figure 2 and Figure 3 The limiting mechanism includes a bidirectional screw 12 fixed to the output end of the motor 11, the output end of the motor 11 extending into the mounting plate 3. Two symmetrical limiting rods 13 are threaded onto the bidirectional screw 12, extending out of the mounting plate 3 and fixedly connected to the limiting strip 5. A limiting component is provided between the limiting rods 13 and the motor 11. The limiting component includes a limiting post 14 fixed in the mounting plate 3, which slides with the limiting rod 13 and penetrates through it. A movable plate 9 is fixed to the telescopic end of the electric telescopic rod 8, and a limiting element is provided between the movable plate 9 and the mounting plate 3. The limiting element includes a controller 16 fixed to the cabinet 1. Positioning sensors 15 are fixed on both the mounting plate 3 and the movable plate 9, and the movable plate 9 is fixedly connected to the pneumatic suction cup 10. The bidirectional screws 12 at the output ends of the two motors 11 are arranged in a cross shape.

[0034] When using the auxiliary fixture, the motor 11 is started, and the rotation of the motor 11 drives the bidirectional screw 12 to rotate. The rotation of the bidirectional screw 12 drives the limiting rod 13 to move. The limiting rod 13 drives the limiting strip 5 to move relative to it, so that the limiting rod 13 slides on the limiting post 14 to limit the limiting rod 13 and limit the placed liquid crystal glass substrate. The bidirectional screw 12 is arranged in a cross shape, which makes it easy to drive the limiting strip 5 to limit the liquid crystal glass substrate from four directions, which can accommodate the limitation of FPC of different sizes. The pneumatic suction cup 10 is used to strengthen the limitation of the liquid crystal glass substrate and reduce the movement of the liquid crystal glass substrate. Then, the positioning sensor 15 on the moving plate 9 and the positioning sensor 15 on the mounting plate 3 are sensed. Through the controller 16, the FPC and the liquid crystal glass substrate are accurately aligned. The electric telescopic rod 8 extends and retracts to drive the pneumatic suction cup 10, so that the FPC and the liquid crystal glass substrate are in contact, reducing the positioning deviation of the FPC. Through the limiting mechanism, the FPC and the liquid crystal glass substrate are accurately aligned, reducing the deviation of the FPC during alignment, improving the processing efficiency and processing quality of the auxiliary fixture, and facilitating the processing of FPC.

[0035] Reference Figure 2 and Figure 4 A pressure sensor 17 is fixed to one side of the limiting strip 5. A limiting plate 18 is fixed to the end of the pressure sensor 17 away from the limiting strip 5. The pressure sensor 17 is electrically connected to the controller 16. A pad 19, which is an elastic rubber pad, is fixed on the limiting plate 18. An electric track 7 is fixed to the lower end of the electric track 6. The electric track 6 and the electric track 7 are arranged in a cross shape. The lower end of the electric track 7 is fixedly connected to the electric telescopic rod 8.

[0036] When the auxiliary fixture is used, the pressure sensor 17 detects the limiting pressure when the limiting strip 5 restricts the FPC. When the detected pressure exceeds the set value, it feeds back to the controller 16. The controller 16 controls the motor 11 to stop, reducing the possibility of damage to the liquid crystal glass substrate by squeezing. The pad 19 is an elastic rubber pad, which increases the friction with the liquid crystal glass substrate, making it easier to restrict and protect the liquid crystal glass substrate. The electric track 1 6 and electric track 2 7 are arranged in a cross shape, which makes it easy for the pneumatic suction cup 10 to drive the FPC to move, making it easy to accurately position and adapt to the restriction of FPCs of different sizes.

[0037] The implementation principle of this embodiment of a universal positioning auxiliary fixture for rapid FPC alignment and pre-compression is as follows: When the auxiliary fixture is used, the electric telescopic rod 8 is activated. The electric telescopic rod 8 extends and retracts, driving the pneumatic suction cup 10 to move. The pneumatic suction cup 10 adsorbs and moves the FPC and liquid crystal glass substrate to be installed. The electric track 1 6 and the electric track 2 7 are in a cross shape, which facilitates the movement of the FPC by the pneumatic suction cup 10 and facilitates accurate positioning. When using the auxiliary fixture, the motor 11 is started, and the rotation of the motor 11 drives the bidirectional screw 12 to rotate. The rotation of the bidirectional screw 12 drives the limiting rod 13 to move. The limiting rod 13 drives the limiting strip 5 to move relative to it, so that the limiting rod 13 slides on the limiting post 14 to limit the limiting rod 13 and limit the placed liquid crystal glass substrate. The bidirectional screw 12 is arranged in a cross shape, which makes it easy to drive the limiting strip 5 to limit the liquid crystal glass substrate from four directions. The pneumatic suction cup 10 is used to strengthen the restriction of the liquid crystal glass substrate and reduce the movement of the liquid crystal glass substrate. Then, the positioning sensor 15 on the moving plate 9 senses the positioning sensor 15 on the mounting plate 3. Through the controller 16, it is easy to accurately align the FPC and the liquid crystal glass substrate. The electric telescopic rod 8 extends and retracts to drive the pneumatic suction cup 10, so that the FPC and the liquid crystal glass substrate are in contact and the positioning deviation of the FPC is reduced. When the auxiliary fixture is used, the pressure sensor 17 detects the limiting pressure when the limiting bar 5 restricts the FPC. When the detected pressure exceeds the set value, it feeds back to the controller 16. The controller 16 controls the motor 11 to stop, reducing the possibility of damage to the liquid crystal glass substrate by squeezing. The pad 19 is an elastic rubber pad, which increases the friction with the liquid crystal glass substrate, making it easier to restrict and protect the liquid crystal glass substrate.
