Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, and in particular to a flexible circuit board loading and unloading device. Background Technology

[0002] In the bonding process of flexible circuit boards, it is usually necessary to automatically unwind and rewind the roll of flexible circuit board base tape to achieve continuous production.

[0003] However, existing unwinding devices suffer from numerous technical problems during operation: traditional unwinding mechanisms often employ mechanical friction braking or simple motor control, making it difficult to maintain constant tension. Due to the softness of the flexible circuit board material, tension fluctuations can cause baseband stretching and deformation, affecting the precise positioning of the circuitry and causing misalignment in subsequent IC bonding processes, thus reducing product yield. During the unwinding process, the protective film peeling off the flexible circuit board baseband generates static electricity with voltages reaching thousands of volts. If this static electricity cannot be effectively eliminated, it may damage the sensitive circuitry of the IC chip, leading to product failure. Existing equipment typically requires manual intervention during roll changes, resulting in prolonged production line downtime and impacting production efficiency. Furthermore, some tension adjustment mechanisms have complex structures and high maintenance costs.

[0004] The above information disclosed in the background art of this utility model is only used to understand the background of the concept of this utility model, and may include information that does not constitute prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a flexible circuit board take-up and untake-up device to address the above problems.

[0006] A flexible circuit board loading and unloading device, comprising:

[0007] frame;

[0008] A feeding tray is provided on the frame and its outer peripheral surface is used for stacking and winding flexible circuit boards and protective films. The flexible circuit boards and the protective films are separated from each other after being released from the feeding tray.

[0009] A take-up tray, which is disposed on the frame and used to connect with the protective film to wind up the protective film;

[0010] A material pulling mechanism is connected to the flexible circuit board and is used to pull the flexible circuit board to transfer the flexible circuit board to other workstations;

[0011] An antistatic device is provided on the frame and located between the feeding tray and the pulling mechanism. The antistatic device is used to remove static electricity from the flexible circuit board.

[0012] The aforementioned flexible printed circuit board (FPCB) unloading and take-up equipment achieves at least the following beneficial effects: The FPCB and protective film are layered and wound on the unloading tray, automatically separating after unloading, and the protective film is independently retrieved by the take-up tray, reducing manual intervention and improving production efficiency. A pulling mechanism automatically pulls the FPCB to the next station, while the take-up tray simultaneously retrieves the protective film, reducing manual roll-changing operations, shortening downtime, and improving production efficiency. Through the synergistic action of the unloading tray and pulling mechanism, the FPCB maintains constant tension during transport, avoiding substrate stretching deformation or displacement caused by tension fluctuations, thus improving the accuracy of subsequent bonding processes. An antistatic device is installed between the unloading tray and the pulling mechanism to neutralize static electricity during FPCB transport, preventing damage to the circuit caused by static electricity from protective film peeling, and improving product yield. The equipment has a reasonable overall layout, with the unloading tray, take-up tray, pulling mechanism, and antistatic device integrated on the frame, making it suitable for the production needs of FPCBs of different specifications, and possessing high versatility and scalability.

[0013] In some embodiments, the static eliminator is a static eliminator blower. Before the flexible circuit board reaches the feeding mechanism, the static eliminator blower can remove dust from the surface of the flexible circuit board and perform static elimination treatment. The static eliminator blower is disposed on the flexible circuit board transport path, located between the unloading tray and the feeding mechanism. After the flexible circuit board is released from the unloading tray and the protective film is peeled off, the static eliminator blower can neutralize the static electricity generated on the surface of the flexible circuit board due to the peeling of the protective film by using ion air, avoiding static accumulation that could lead to IC circuit breakdown or dust adsorption, thus improving product reliability. The high-speed airflow of the static eliminator blower can blow away tiny particles and dust on the surface of the flexible circuit board, reducing foreign object interference in subsequent bonding or surface mount processes, and improving processing accuracy and yield. Using a blowing method for static elimination and cleaning avoids mechanical contact that could cause scratches or deformation to the flexible board, making it particularly suitable for processing ultra-thin, high-precision flexible circuit boards. The anti-static blower head can be adjusted dynamically in real time to match the transmission speed of the feeding mechanism, ensuring that static electricity and dust can still be effectively removed during high-speed feeding.

[0014] In some embodiments, the static eliminator is an ionizing air bar. For example, the ionizing air bar can be positioned on the transport path of the flexible circuit board, between the unloading tray and the pulling mechanism. After the flexible circuit board is released from the unloading tray and separated from the protective film, the ionizing air bar can efficiently eliminate static electricity on the board surface and can optionally be equipped with an auxiliary cleaning function. The ionizing air bar generates positive and negative ions by ionizing air with high voltage, quickly neutralizing the static electricity generated on the surface of the flexible circuit board due to the peeling or friction of the protective film, preventing static electricity from damaging sensitive electronic components or attracting dust.

[0015] In some embodiments, the static eliminator is a grounding roller. After the flexible circuit board is released from the feeding tray and separated from the protective film, the grounding roller conducts static electricity from the board surface to the ground through physical contact, thus eliminating static electricity. By directly contacting the surface of the flexible circuit board, the grounding roller rapidly conducts accumulated static charge to the ground, requiring no additional power supply or consumables, making it suitable for cost-sensitive production lines. It contains no electronic components or high-voltage parts, is less affected by environmental temperature and humidity, and exhibits high stability over long-term use.

[0016] In some embodiments, the flexible circuit board loading and unloading device further includes a tensioning roller rotatably mounted on the frame, through which the flexible circuit board passes before being connected to the pulling mechanism. The tensioning roller can automatically adjust its position or apply tension according to the transmission status of the flexible circuit board, ensuring the board remains stable during transmission and preventing slackness, displacement, or excessive stretching of the flexible circuit board.

[0017] In some embodiments, the tensioning wheel is a gravity wheel. This gravity wheel applies a constant tension to the flexible circuit board it passes through using its own weight or additional counterweights, ensuring the board remains under appropriate tension throughout the transport process and preventing slack or overload. No additional power or complex control mechanisms are required; tension is automatically adjusted by gravity, reducing potential equipment failure points and lowering maintenance costs. When the feeding speed changes abruptly or the length of the flexible circuit board changes, the gravity wheel absorbs tension fluctuations in real time by floating up and down, preventing the board from breaking or wrinkling.

[0018] In some embodiments, the flexible circuit board take-up and unload device includes guide wheels rotatably mounted on the frame, and the protective film passes around the guide wheels before being received by the take-up tray. The guide wheels can precisely guide the direction of the protective film, keeping it synchronized with the peeling or bonding process of the flexible circuit board, reducing uneven winding or film waste caused by path deviation. By properly arranging the position of the guide wheels, the tension distribution of the protective film can be adjusted, preventing wrinkling or breakage of the film layer due to localized excessive tightness or looseness on the take-up tray. The surface of the guide wheels can be coated with a low-friction material (such as Teflon or silicone) to prevent the protective film from being scratched or generating static electricity during high-speed winding.

[0019] In some embodiments, the guide wheel includes a first guide wheel and a second guide wheel spaced apart, and the flexible circuit board is connected to the receiving tray after passing around the first guide wheel and the second guide wheel.

[0020] In some embodiments, the flexible circuit board receiving and unloading equipment includes a first driving device and a second driving device disposed on the frame. The first driving device is connected to the unloading tray and is used to drive the unloading tray to rotate. The second driving device is connected to the receiving tray and is used to drive the receiving tray to rotate.

[0021] In some embodiments, the first drive device includes a first motor, an electromagnetic clutch, and an unwinding shaft. The unwinding tray is disposed on the unwinding shaft, which is inserted into the electromagnetic clutch. The drive end of the electromagnetic clutch is connected to the first motor. This structure utilizes the rapid response characteristics of the electromagnetic clutch to achieve precise start-stop and tension buffering of the unwinding tray, making it particularly suitable for scenarios requiring frequent switching of unwinding states (such as intermittent unwinding / rewinding, web correction, or pauses at inspection stations). The electromagnetic clutch can engage or disengage power transmission within milliseconds, preventing overshoot of the unwinding tray due to motor inertia (e.g., instantaneous shaft locking during emergency stops to prevent flexible circuit boards from loosening). By adjusting the excitation current of the electromagnetic clutch, the torque transmitted to the unwinding shaft can be controlled, achieving stepless adjustment of the unwinding tension (e.g., increasing the current for thicker substrates to provide higher reverse resistance).

[0022] In some embodiments, the second drive device includes a second motor and a take-up shaft connected to the second motor, with the take-up tray disposed on the take-up shaft.

[0023] In some embodiments, the flexible circuit board take-up and unwrap device further includes a control panel with a first knob and a second knob. The first knob controls the rotation speed of the first motor to adjust the unwinding speed of the unwinding reel, and the second knob controls the torque of the second motor to adjust the tension of the take-up reel on the protective film. This flexible circuit board take-up and unwrap device achieves independent and precise control of the unwinding speed and winding tension by setting the first and second knobs on the control panel: the first knob controls the unwinding speed of the unwinding reel by adjusting the rotation speed of the first motor, ensuring stable substrate transport; the second knob controls the tension of the take-up reel on the protective film by adjusting the torque of the second motor, effectively preventing the film from becoming too loose or too tight. This design not only simplifies the operation process and improves production efficiency, but also adapts to different process requirements, ensuring the flatness and product quality of the flexible circuit board during the take-up and unwrap process.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, the present invention provides a flexible circuit board receiving and unloading device 10, which includes a frame 100, a feeding tray 200, a receiving tray 300, a pulling mechanism 400, and an antistatic device 500. The feeding tray 200 is disposed on the frame 100, and its outer peripheral surface is used for stacking and winding the flexible circuit board 610 and the protective film 620. The flexible circuit board 610 and the protective film 620 separate from each other after being released from the feeding tray 200. The receiving tray 300 is disposed on the frame 100 and is used to connect with the protective film 620 to wind up the protective film 620. The pulling mechanism 400 is connected to the flexible circuit board 610 and is used to pull the flexible circuit board 610 to transfer it to other workstations. The static eliminator 500 is disposed on the frame 100 and located between the feeding tray 200 and the pulling mechanism 400. The static eliminator 500 is used to remove static electricity from the flexible circuit board 610.

[0034] The aforementioned flexible circuit board unloading and take-up equipment 10 can achieve at least the following beneficial effects: the flexible circuit board 610 (Flexible Printed Circuit) and protective film 620 are layered and wound on the unloading tray 200, automatically separated after unloading, and the protective film 620 is independently recovered by the take-up tray 300, reducing manual intervention and improving production efficiency. The pull mechanism 400 automatically pulls the flexible circuit board 610 to the next station, while the take-up tray 300 simultaneously recovers the protective film 620, reducing manual roll-changing operations, shortening downtime, and improving production efficiency. Through the synergistic effect of the unloading tray 200 and the pull mechanism 400, the flexible circuit board 610 maintains constant tension during transmission, avoiding substrate stretching deformation or displacement caused by tension fluctuations, and improving the accuracy of subsequent bonding processes. An antistatic device 500 is installed between the feeding tray 200 and the pulling mechanism 400. It neutralizes static electricity during the transport of the flexible circuit board 610, preventing damage to the circuit caused by static electricity generated during the peeling of the protective film 620 and improving product yield. The equipment has a reasonable overall layout, with the feeding tray 200, receiving tray 300, pulling mechanism 400, and antistatic device 500 integrated on the frame 100. It is suitable for the production needs of flexible circuit boards 610 of different specifications, and has high versatility and scalability.

[0035] In some embodiments, the static eliminator 500 is a static eliminator blower. Before the flexible circuit board 610 reaches the feeding mechanism, the static eliminator blower can remove dust from the surface of the flexible circuit board 610 and perform static elimination treatment. The static eliminator 500 is a static eliminator blower, which is disposed on the transport path of the flexible circuit board 610, located between the unloading tray 200 and the feeding mechanism 400. When the flexible circuit board 610 is released from the unloading tray 200 and the protective film 620 is peeled off, the static eliminator blower can neutralize the static electricity generated on the surface of the flexible circuit board 610 due to the peeling of the protective film 620 by using ion air, avoiding static accumulation that could cause IC circuit breakdown or dust adsorption, thus improving product reliability. The high-speed airflow of the static eliminator blower can sweep away tiny particles and dust on the surface of the flexible circuit board 610, reducing foreign object interference in subsequent bonding or surface mount processes, and improving processing accuracy and yield. This system uses a blowing method for static electricity removal and cleaning, avoiding mechanical contact that could scratch or deform the flexible substrate. It is especially suitable for processing ultra-thin, high-precision flexible circuit boards 610. The static-removing blower head can be dynamically adjusted in real time to match the conveying speed of the feeding mechanism 400, ensuring effective removal of static electricity and dust even during high-speed feeding.

[0036] In some embodiments, the static eliminator 500 is an ionizer. For example, the ionizer can be positioned on the transport path of the flexible circuit board 610, between the unloading tray 200 and the pulling mechanism 400. When the flexible circuit board 610 is released from the unloading tray 200 and separated from the protective film 620, the ionizer can efficiently eliminate static electricity on the board surface and can optionally be equipped with an auxiliary cleaning function. The ionizer generates positive and negative ions by ionizing air with high voltage, quickly neutralizing the static electricity generated on the surface of the flexible circuit board 610 due to the peeling or friction of the protective film 620, preventing static electricity from damaging sensitive electronic components or attracting dust.

[0037] In some embodiments, the static eliminator 500 is a grounding roller. When the flexible circuit board 610 is released from the feeding tray 200 and separated from the protective film 620, the grounding roller conducts static electricity from the board surface to the ground through physical contact, thus eliminating static electricity. By directly contacting the surface of the flexible circuit board 610, the grounding roller rapidly conducts accumulated static charge to the ground without requiring additional power supply or consumables, making it suitable for cost-sensitive production lines. It contains no electronic components or high-voltage parts, is less affected by environmental temperature and humidity, and exhibits high stability over long-term use.

[0038] like Figure 2 As shown, in some embodiments, the flexible circuit board take-up and unload device 10 further includes a tensioning roller 710 rotatably disposed on the frame 100, and the flexible circuit board 610 passes around the tensioning roller 710 before being connected to the pulling mechanism 400. The flexible circuit board take-up and unload device 10 also includes a tensioning roller 710 rotatably disposed on the frame 100, and the flexible circuit board 610 passes around the tensioning roller 710 before being connected to the pulling mechanism 400. The tensioning roller 710 can automatically adjust its position or apply tension according to the transmission state of the flexible circuit board 610, ensuring the board remains stable during transmission and preventing the flexible circuit board 610 from slackening, shifting, or being overstretched.

[0039] In some embodiments, the tensioning wheel 710 is a gravity wheel. The tensioning wheel 710, being a gravity wheel, applies a constant tension to the flexible circuit board 610 it passes through, using its own weight or additional counterweights, ensuring the board remains under appropriate tension during transport and preventing slack or overload. No additional power or complex control mechanisms are required; tension is automatically adjusted by gravity, reducing potential equipment failure points and lowering maintenance costs. When the feeding speed changes abruptly or the length of the flexible circuit board 610 changes, the gravity wheel absorbs tension fluctuations in real time by floating up and down, preventing the board from breaking or wrinkling.

[0040] like Figure 2As shown, in some embodiments, the flexible circuit board take-up and unload device 10 includes guide wheels 720 rotatably mounted on the frame 100. The protective film 620 passes around the guide wheels 720 and is then connected to the take-up tray 300. The guide wheels 720 can precisely guide the direction of the protective film 620, keeping it synchronized with the peeling or bonding process of the flexible circuit board 610, reducing uneven winding or film waste caused by path deviation. By reasonably arranging the position of the guide wheels 720, the tension distribution of the protective film 620 can be adjusted, preventing the film layer from wrinkling or breaking due to localized excessive tightness or looseness of the take-up tray 300. The surface of the guide wheels 720 can be coated with a low-friction material (such as Teflon or silicone) to prevent the protective film 620 from being scratched or generating static electricity during high-speed winding.

[0041] like Figure 2 As shown, in some embodiments, the guide wheel 720 includes a first guide wheel 721 and a second guide wheel 722 spaced apart, and the flexible circuit board 610 is connected to the receiving tray 300 after passing around the first guide wheel 721 and the second guide wheel 722.

[0042] like Figure 4 and Figure 5 As shown, in some embodiments, the flexible circuit board take-up and untake-up device 10 includes a first drive device 810 and a second drive device 820 disposed on the frame 100. The first drive device 810 is connected to the untake-up tray 200 and is used to drive the untake-up tray 200 to rotate. The second drive device 820 is connected to the take-up tray 300 and is used to drive the take-up tray 300 to rotate.

[0043] like Figure 4 As shown, in some embodiments, the first drive device 810 includes a first motor 811, an electromagnetic clutch 812, and an unwinding shaft 813. The unwinding tray 200 is disposed on the unwinding shaft 813, which is inserted into the electromagnetic clutch 812. The drive end of the electromagnetic clutch 812 is connected to the first motor 811. This structure utilizes the rapid response characteristics of the electromagnetic clutch 812 to achieve precise start-stop and tension buffering of the unwinding tray 200, making it particularly suitable for scenarios requiring frequent switching of unwinding states (such as intermittent unwinding and rewinding, web correction, or pause at the inspection station). The electromagnetic clutch 812 can engage or disengage power transmission within milliseconds, preventing overshoot of the unwinding tray 200 due to motor inertia (e.g., instantaneous shaft locking during emergency stops to prevent the flexible circuit board 610 from loosening). By adjusting the excitation current of the electromagnetic clutch 812, the torque transmitted to the unwinding shaft 813 can be controlled, achieving stepless adjustment of the unwinding tension (e.g., increasing the current for thicker substrates to provide higher reverse resistance).

[0044] like Figure 5As shown, in some embodiments, the second drive device 820 includes a second motor 821 and a take-up shaft 822 connected to the second motor 821, and the take-up tray 300 is disposed on the take-up shaft 822.

[0045] like Figure 2 As shown, in some embodiments, the flexible circuit board take-up and unwrap device 10 further includes a control panel 900. The control panel 900 has a first knob 910 and a second knob 920. The first knob 910 controls the rotational speed of the first motor 811 to adjust the unwinding speed of the unloading tray 200. The second knob 920 controls the torque of the second motor 821 to adjust the tension of the take-up tray 300 on the protective film 620. This flexible circuit board take-up and unwrap device 10 achieves independent and precise control of the unwinding speed and winding tension by setting the first knob 910 and the second knob 920 on the control panel 900: the first knob 910 controls the unwinding speed of the unloading tray 200 by adjusting the rotational speed of the first motor 811, ensuring stable substrate transport; the second knob 920 controls the tension of the take-up tray 300 on the protective film 620 by adjusting the torque of the second motor 821, effectively preventing the film from becoming too loose or too tight. This design not only simplifies the operation process and improves production efficiency, but also adapts to different process requirements, ensuring the flatness and product quality of the flexible circuit board 610 during the unfolding and rewinding process.
