Description

Technical Field

[0001] This invention relates to the field of PCB processing technology, specifically to a device and method for tearing adhesive tape from gold fingers. Background Technology

[0002] In the electronics manufacturing industry, printed circuit boards (PCBs) serve as the core carriers of electronic components, and the degree of automation, precision, and efficiency of their production and processing directly affect the quality and production capacity of end products. With the increasing demand for miniaturized and high-density PCBs from industries such as consumer electronics and automotive electronics, processes involved in PCB manufacturing, such as gold finger protection, stencil coordination, transfer positioning, and quality inspection, face increasingly severe technical challenges. Existing solutions are gradually becoming insufficient to meet the high precision and high stability requirements of industrialized mass production.

[0003] Specifically, in PCB incoming material processing scenarios, the common form of incoming material is the movement of PCBs in a carrier, with gold finger tape attached to the bottom of the PCB to protect the gold fingers. However, existing automated processing solutions for this type of incoming material have the following key technical problems:

[0004] On the one hand, the process of removing and recycling gold finger tape suffers from low automation and poor reliability. Currently, most production lines still rely on semi-automatic equipment for removing gold finger tape. While this equipment can perform some removal, it often results in misalignment of the PCB board, leading to damage to the gold finger plating. Especially during transport, the PCB board may shift position due to vibrations and shaking, further reducing the quality of the tape removal. Simultaneously, the transfer of PCBs between tape removal and carrier insertion processes relies heavily on a single handling mechanism. This mechanism is not only inefficient and lacks the precision to adapt to different product models, but also struggles to effectively mitigate assembly errors caused by minor PCB shifts before and after tape removal, as well as positioning deviations in the carrier itself. Consequently, the defect rate remains consistently high.

[0005] On the other hand, the recycling process of the removed waste tape lacks an effective closed-loop treatment. The waste tape is easily scattered inside the equipment or in the production environment, which may not only block moving parts and affect the normal operation of the equipment, but also cause short circuits or poor contact of components due to residual adhesive debris adhering to the PCB surface.

[0006] In summary, current PCB manufacturing processes generally suffer from low automation, insufficient precision, poor reliability, and low efficiency in areas such as gold finger tape processing, steel sheet coordination, transfer positioning, and quality inspection. There is an urgent need for a technical solution that can achieve full-process automation and high-precision collaborative control to overcome the shortcomings of existing technologies and meet the needs of industrialized mass production.

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0044] Example 1:

[0045] See Figure 1 and Figure 2As shown, this embodiment provides a gold finger adhesive tape tearing device, which includes: a transmission mechanism 100, the transmission mechanism 100 including a transmission frame 110 and a carrier fixture 130, the transmission frame 110 having at least one transmission channel 114, the carrier fixture 130 including a carrier tray 131 and a pressure plate 132, the carrier tray 131 being disposed on the transmission frame 110 and movable along the transmission channel 114, having a receiving groove thereon, the pressure plate 132 being snap-fitted to the carrier tray 131 to fix the components to be torn in the receiving groove; and a conveying mechanism 200, which includes a pressure plate transfer assembly 230 and a component transfer assembly 220, the pressure plate transfer assembly 230 including a pressure plate transfer frame 232 movable toward / away from the transmission channel 114, the pressure plate transfer frame 232 having a plurality of pressure plate suction nozzles 2321 for adsorption and connection. The pressure plate 132 and the component transfer assembly 220 include a material picking module 225, which is provided with multiple component suction nozzles 2257 to adsorb and connect the components to be peeled off; the film removal mechanism 300 includes a film tearing assembly 310 and a recycling assembly 320. The film tearing assembly 310 can clamp and move the component protective film away from the component to be peeled off in the component transfer assembly 220. The recycling assembly 320 includes an anti-sticking claw 323, a film pushing rod 325 and a waste box 327. The anti-sticking claw 323 can move between the film tearing assembly 310 and the component transfer assembly 220 to clamp the protective film detached from the component. The waste box 327 is located below the anti-sticking claw 323. The film pushing rod 325 moves against the anti-sticking claw 323 to make the peeled protective film detach from the anti-sticking claw 323.

[0046] The gold finger tape tearing device of the present invention, through the coordinated operation of the transmission mechanism 100, the handling mechanism 200 and the film removal mechanism 300, constructs a fully automated operation system from the loading and fixing of the components to be peeled, the transfer of the pressure plate 132 and the components, to the removal and recycling of the protective film. Among them, the transmission mechanism 100 realizes the stable positioning and transmission of components with the help of the carrier tray 131 receiving groove and the snap-fit ​​pressure plate 132; the handling mechanism 200 completes the automated transfer through the pressure plate transfer assembly 230 and the component transfer assembly 220; and the film removal mechanism 300 realizes the automated removal and recycling of the protective film. The whole process does not require manual intervention, which significantly improves the production efficiency of gold finger tape processing in PCB processing, meets the high-efficiency requirements of industrial mass production, and also improves the quality of film tearing processing.

[0047] It should be noted that, for ease of description, in this embodiment, the width direction of the device is defined as the first direction X, the extension direction of the transmission channel 114 is defined as the second direction Y, and the height direction of the device is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0048] Furthermore, this embodiment also includes a machine base 500 and a control mechanism. The machine base 500 is equipped with a housing 510. The transmission mechanism 100, the handling mechanism 200, and the film removal mechanism 300 are all mounted on the machine base 500 and located inside the housing 510. The machine base 500, the housing 510, and the control mechanism are the basic support, protection, and control core of the gold finger tape tearing device. The three work together to provide key guarantees for the stable and automated operation of the device. The machine base 500 carries the transmission mechanism 100, the handling mechanism 200, and the film removal mechanism 300. The housing 510 adopts a closed design, which can prevent dust, liquids, etc. from entering the interior, preventing problems such as jamming of the transmission guide rail and clogging of the suction nozzle. It can also isolate moving parts to prevent operators from accidentally touching and injuring themselves. It can also reduce the impact of external airflow and temperature fluctuations on the operation and maintain the stable environment required for gold finger processing.

[0049] The control mechanism is located in the machine tool 500 and is connected to the transmission mechanism 100, the handling mechanism 200, and the film removal mechanism 300 via signals. During actual production, operators can use the control mechanism to adjust the above structures in real time, thereby improving the flexibility of the device. Parameters can also be preset through the control mechanism, thereby increasing the degree of automation of the device.

[0050] See Figure 3 and Figure 4As shown, the transmission mechanism 100 is used to achieve stable transport and positioning of components. The transmission frame 110 provides a fixed moving path for the carrying fixture 130 by setting at least one transmission channel 114, ensuring the continuity of the entire film-tearing process. In this embodiment, the transmission mechanism 100 further includes a width adjustment component 120. The transmission frame 110 includes a fixed frame 111 and a movable frame 112. Both the fixed frame 111 and the movable frame 112 are provided with transmission belts 113, and the fixed frame 111 and the movable frame 112 together enclose a transmission channel 114. The width adjustment component 120 includes at least one screw 121 and a width adjustment driver 122. The screw 121 extends along the width direction of the transmission channel 114, with one end fixed to the fixed frame 111 and the other end passing through and connecting to the movable frame 112, and threadedly engaging with the movable frame 112. The width adjustment driver 122 is connected to the screw 121 to drive the screw 121 to rotate. The movable frame 112 can move relative to the fixed frame 111 through the screw 121 to adjust the width of the transmission channel 114.

[0051] Specifically, in this embodiment, the fixed frame 111 serves as the reference component of the transmission frame 110, providing stable support for the overall structure. Its surface transmission belt 113 provides transmission power to the carrying fixture 130 on one side, and simultaneously cooperates with the movable frame 112 to form the fixed boundary of the transmission channel 114, ensuring reference stability during width adjustment. The movable frame 112, as a movable component of the transmission frame 110, provides transmission power to the carrying fixture 130 on the other side via its surface transmission belt 113. Driven by the width adjustment component 120, it can move relative to the fixed frame 111, changing the distance between them, thereby adjusting the width of the transmission channel 114 to accommodate carrying fixtures 130 of different sizes. The width adjustment driver 122 provides power output, driving the screw 121 to rotate via a transmission wheel and transmission belt. The screw 121 converts the rotational motion of the width adjustment driver 122 into the linear motion of the movable frame 112, thereby achieving precise adjustment of the channel width. Based on the above structure, the transmission mechanism 100 in this embodiment can be adapted to different sizes of film-to-be-torn components and carrier fixtures 130.

[0052] In this embodiment, the receiving groove on the carrier plate 131 is used to accurately place the components to be peeled off. The snap-fit ​​connection between the pressure plate 132 and the carrier plate 131 can firmly fix the components in the receiving groove, avoiding positional deviations caused by vibration and displacement during transmission, and providing a stable reference for subsequent film peeling operations. It is especially suitable for the positioning needs of precision components such as gold fingers.

[0053] Furthermore, the transmission mechanism 100 in this embodiment also includes a positioning stop assembly 140, which is set at the transport station on the transmission channel 114. The positioning stop assembly 140 includes a stop driver 141, a stop block 142, and an elastic element 143. The stop driver 141 is located below the transmission channel 114. The stop block 142 is connected to the working end of the stop driver 141 and moves up and down at the material output end of the transport station via the stop driver 141. The elastic element 143 is connected to the side of the stop block 142 facing the carrying fixture 130 and moves synchronously with the stop driver 141 to stop / avoid the carrying fixture 130. The stop driver 141, as a power source, is installed below the transmission channel 114. By driving the stop block 142 to rise and fall, it controls the blocking and release of the carrying fixture 130, thereby ensuring that the carrying fixture 130 accurately stops at the transport station. The stop block 142 moves up and down at the material output end of the conveying station under the drive of the driver. When it rises, it can physically block the carrier fixture 130 from continuing to transport, ensuring that it is accurately positioned at the conveying station. When it falls, it completely avoids the carrier fixture 130, allowing it to pass through, thus realizing automated control of station switching. The elastic element 143 moves synchronously with the stop block 142. When the stop block 142 blocks the carrier fixture 130, the elastic element 143 can buffer the impact force at the moment of contact between the two, avoiding rigid collisions that could cause the carrier fixture 130 to shift, components to shake, or equipment to wear. At the same time, it ensures the stability of the blockage and prevents the carrier fixture 130 from overshooting the stop position due to inertia.

[0054] Furthermore, the transmission mechanism 100 in this embodiment also includes a lifting component 150, which is set corresponding to the transport station on the transmission channel 114. The lifting component 150 includes a lifting driver 151 and a lifting frame 152. The lifting driver 151 is located below the transport station, and the lifting frame 152 is connected to the working end of the lifting driver 151 to lift the carrying fixture 130 in the transport station away from the transmission frame 110. The lifting driver 151 provides driving force for the lifting action of the carrying fixture 130, ensuring that the lifting frame 152 rises and falls stably at a preset height, and is the power core of the lifting component 150. The lifting frame 152 is connected to the working end of the lifting driver 151, and under the drive of the driver, lifts the carrying fixture 130 in the transport station upwards, causing it to detach from the transmission belt 113 on the transmission frame 110. This action can prevent the carrier fixture 130 from being misaligned due to slight vibration or displacement of the transmission belt 113 when the handling mechanism 200 is performing pick-up and put-down operations, thus providing a stable positioning reference for subsequent operations. At the same time, it eliminates frictional interference between the transmission mechanism 100 and the carrier fixture 130, ensuring the accuracy of the pick-up and put-down operations.

[0055] See Figures 5 to 8As shown, in this embodiment, the conveying mechanism 200 achieves material transfer between different processes through the coordinated operation of the pressure plate transfer assembly 230 and the component transfer assembly 220. The pressure plate transfer assembly 230, through a movable pressure plate transfer frame 232 and multiple pressure plate suction nozzles 2321, precisely adsorbs and removes the pressure plate 132, releasing the pressure plate 132 from fixing the components and providing operating space for subsequent material handling and film removal. After film removal, the pressure plate 132 can be reattached to the carrier tray 131, thereby achieving automated loading and unloading. The multiple component suction nozzles 2257 on the material handling module 225 adsorb the components to be peeled using negative pressure, stably gripping the components and transferring them to the film removal station, while maintaining the fixed posture of the components during the film removal process, ensuring the relative position of the protective film and the components is stable, facilitating precise clamping of the protective film edge by the film removal assembly 310.

[0056] Furthermore, the conveying mechanism in this embodiment also includes a support frame 210, on which a first horizontal module 211 and a second horizontal module 212 are provided. Both the first horizontal module 211 and the second horizontal module 212 extend along a first direction X. The component transfer assembly 220 is slidably connected to the first horizontal module 211, and the pressure plate transfer assembly 230 is slidably connected to the second horizontal module 212.

[0057] The first horizontal module 211 extends along the first direction X and is slidably connected to the component transfer assembly 220. On the one hand, it provides a stable guide track for the component transfer assembly 220, restricting its movement to only along the preset first direction X, ensuring that the material handling module 225 can accurately reach the corresponding position of the support fixture 130. On the other hand, it drives the component transfer assembly 220 to achieve smooth and precise displacement adjustment in the first direction X, meeting the pick-and-place requirements of components of different workstations or different specifications. The second horizontal module 212 also extends along the first direction X and is slidably connected to the pressure plate transfer assembly 230. Its function is similar to that of the first horizontal module 211, specifically providing guidance and drive for the pressure plate transfer assembly 230 in the first direction X, so that the pressure plate transfer frame 232 can accurately move above the support fixture 130 to complete the adsorption and transfer operation of the pressure plate 132. By independently setting the first horizontal module 211 and the second horizontal module 212, the component transfer assembly 220 and the pressure plate transfer assembly 230 can move independently in the same direction, avoiding mutual interference between their actions and improving handling efficiency and operational flexibility.

[0058] In this embodiment, the component transfer assembly 220 includes a horizontal slide 221, a first lifting module 222, and a lifting slide 223. The horizontal slide 221 is slidably connected to the first horizontal module 211, and a third horizontal module 2211 extending along the second direction Y is provided thereon. The first lifting module 222 is slidably connected to the third horizontal module 2211 and extends along the third direction Z. The lifting slide 223 is slidably connected to the first lifting module 222, and the material handling module 225 is connected to the lifting slide 223. The pressure plate transfer assembly 230 includes a second lifting module extending along the third direction Z, and the pressure plate transfer frame 232 is slidably connected to the second lifting module. Based on the above structure, the pressure plate transfer frame 232 and the material handling module 225 can move flexibly.

[0059] Specifically, the material handling module 225 in this embodiment includes an assembly plate 2252, a floating plate 2253, a pressing driver 2251, a shape-changing adsorption plate 2255, and a shape-changing gripper 2256. The pressing driver 2251 is disposed on the lifting slide 223, the assembly plate 2252 is connected to the working end of the pressing driver 2251, the floating plate 2253 and the assembly plate 2252 are connected by multiple floating guide rods 2254, the shape-changing gripper 2256 is disposed on the floating plate 2253 and can open and close relative to it to clamp and connect the shape-changing adsorption plate 2255, and multiple component suction nozzles 2257 are connected to the shape-changing adsorption plate 2255. The pressure actuator 2251 is mounted on the lifting slide 223 and serves as the power source for the material handling module 225. It drives the assembly plate 2252 to move along the third direction (Z), providing pressure regulation for the adsorption and placement of components. This ensures that the component suction nozzle 2257 contacts the component surface with appropriate force, guaranteeing both strong adsorption and preventing damage from excessive pressure. The assembly plate 2252 is connected to the working end of the pressure actuator 2251. It transmits power to the pressure actuator 2251 and connects to the floating plate 2253 via floating guide rods 2254, providing an installation reference for subsequent components and coordinating the pressure action with the floating buffer. The floating plate 2253 is connected to the assembly plate 2252 via multiple floating guide rods 2254, allowing it to float slightly relative to the assembly plate 2252, providing a buffer during material handling. The change-change gripper 2256 is used to quickly replace the change-change adsorption plate 2255. When different specifications of components need to be processed, the gripper releases the old change-change adsorption plate 2255 and clamps and fixes the new, compatible change-change adsorption plate 2255, realizing the rapid change of component suction nozzles 2257 without the need to completely disassemble the material handling module 225, greatly improving the device's adaptability to multiple types of components. Multiple component suction nozzles 2257 are connected to the change-change adsorption plate 2255 and can be quickly replaced via the change-change gripper 2256. Different change-change adsorption plates 2255 can be configured with corresponding numbers, spacing, and types of suction nozzles according to the size and shape of the components, meeting diverse adsorption needs and is a key component in realizing the versatility of the material handling module 225. The component suction nozzle 2257 uses negative pressure to adsorb the components to be peeled off, directly contacting the components and completing the gripping action. Its number and layout match the changing adsorption plate 2255 to ensure stable adsorption of components of different specifications, providing reliable material clamping for the subsequent film peeling process.

[0060] See Figure 9 and Figure 10As shown, in this embodiment, the film removal mechanism 300 completes the peeling and processing of the protective film through the cooperation of the film tearing assembly 310 and the recycling assembly 320. The film tearing assembly 310 clamps the edge of the protective film and moves it away from the component, using tension to separate the protective film from the component, thus achieving automated film tearing. The anti-sticking claws 323 in the recycling assembly 320 clamp the waste material in time after the protective film is separated from the component, preventing it from adhering to the component or equipment due to static electricity or stickiness. The film pushing rod 325 moves in conjunction with the anti-sticking claws 323, which can peel the protective film off the claws and push it into the waste box 327 below, thus achieving automatic collection of waste material, avoiding the impact of protective film residue on subsequent processes, and keeping the inside of the equipment clean.

[0061] Furthermore, the film removal mechanism 300 also includes an ion generator 330, which is positioned towards the film-peeling assembly 310. The film-peeling assembly 310, the ion generator 330, and the anti-stick gripper 323 are arranged around the waste box 327. The ion generator 330 can release positive and negative ions to neutralize the static electricity generated during the film peeling process due to friction between the protective film and components. Since precision components such as gold fingers are sensitive to static electricity, static electricity may damage components or attract dust and impurities. By eliminating static electricity, the ion generator 330 can avoid static interference during the peeling of the protective film, ensuring that the performance of components is not affected. At the same time, it prevents the protective film from sticking to the surface of the equipment or components due to static electricity, ensuring a smooth film peeling process.

[0062] In this embodiment, the film-tearing assembly 310 includes a film-tearing guide rail 311, a movable base frame 312, a fixed clamping plate 314, a movable clamping plate 315, and a clamping plate driver 313. The film-tearing guide rail 311 is disposed on one side of the waste box 327. The movable base frame 312 is slidably connected to the film-tearing guide rail 311. The fixed clamping plate 314 is disposed on the top of the movable base frame 312. The clamping plate driver 313 is connected to one side of the movable base frame 312, and its working end is connected to the movable clamping plate 315 to drive the movable clamping plate 315 to move up and down above the fixed clamping plate 314. The film-tearing guide rail 311 provides a stable sliding guide for the movable base frame 312, limiting its movement along a preset trajectory, ensuring the straightness and accuracy of the film-tearing action, and enabling the clamping plate to accurately align with the protective film. The movable base frame 312 serves as the mounting carrier for the fixed clamping plate 314, the movable clamping plate 315, and the clamping plate driver 313. It can move along the film-tearing guide rail 311, bringing the clamping plate assembly closer to the component to be peeled, or moving away from the component after clamping the protective film to complete the peeling action. The fixed clamping plate 314 is located on the top of the movable base frame 312 and serves as a fixed reference surface for clamping the protective film. During film peeling, it cooperates with the movable clamping plate 315 to form a clamping force. When the edge of the protective film is placed on the fixed clamping plate 314, the fixed clamping plate 314 provides bottom support to ensure the stability of the clamping. Correspondingly, the movable clamping plate 315 is connected to the working end of the clamping plate driver 313. Under the drive of the driver, it moves up and down above the fixed clamping plate 314: when descending, it clamps the edge of the protective film together with the fixed clamping plate 314 to provide a reliable clamping force; when rising, it releases the protective film to facilitate the removal or transfer of waste materials.

[0063] In this embodiment, the recycling component 320 includes a recycling adjustment guide rail 321, a recycling base frame 322, a gripper driver 324, and a film pusher driver 326. The recycling adjustment guide rail 321 is disposed on one side of the waste box 327. The recycling base frame 322 is slidably connected to the recycling adjustment guide rail 321. The gripper driver 324 is disposed on the recycling base frame 322 and is connected to the anti-stick gripper 323 to drive the anti-stick gripper 323 to move relative to each other in the third direction Z. The film pusher driver 326 is disposed at one end of the gripper driver 324, and its working end is connected to the film pusher rod 325 to drive the film pusher rod 325 to move towards the waste box 327 while adhering to the surface of the anti-stick gripper 323.

[0064] The recycling base frame 322 is slidably connected to the recycling adjustment guide rail 321, serving as the mounting carrier for the gripper driver 324, the film pusher driver 326, and the anti-stick gripper 323. By moving along the guide rail, it drives the entire recycling actuator to adjust its position, achieving precise coordination with the film-tearing assembly 310 and ensuring that the protective film is promptly clamped after detaching from the components. The gripper driver 324 is mounted on the recycling base frame 322 and connected to the anti-stick gripper 323, providing the anti-stick gripper 323 with an opening and closing driving force in the Z-direction. The film pusher driver 326 is located at one end of the gripper driver 324 and connected to the film pusher rod 325, providing the film pusher rod 325 with the moving power along the surface of the anti-stick gripper 323 towards the waste box 327. This drives the film pusher rod 325 to peel off the protective film held on the anti-stick gripper 323 and push it into the waste box 327, completing automated waste processing and preventing protective film residue on the gripper from affecting subsequent recycling operations.

[0065] Furthermore, in this embodiment, the exhaust port at the bottom of the waste box 327 forms a negative pressure environment through an external suction device. When the pusher rod 325 pushes the protective film into the waste box 327, the suction force generated by the exhaust port can quickly adsorb the falling protective film to the bottom of the waste box 327, preventing it from floating, accumulating at the box opening, or rebounding and overflowing due to static electricity, airflow, or its own elasticity.

[0066] Furthermore, the layout of the film-tearing assembly 310, ion generator 330, and anti-stick gripper 323 surrounding the waste container 327 in this embodiment forms a compact and efficient film removal unit. This layout allows the protective film peeled off by the film-tearing assembly 310 to be held by the anti-stick gripper 323 within a short distance, reducing the floating time of the protective film in the air; the ion generator 330 can directly act on the film-tearing area and the protective film transfer path, ensuring maximum electrostatic neutralization effect; at the same time, the anti-stick gripper 323 is close to the waste container 327, which facilitates the pusher rod 325 to quickly push the protective film into the waste container 327, shortening the waste processing path, improving the overall film removal efficiency, and reducing space occupation.

[0067] This embodiment also includes a barcode scanning camera 224 and a quality inspection camera 400. The barcode scanning camera 224 is connected to the component transfer assembly 220 and moves synchronously with the material handling module 225. The quality inspection camera 400 is located on one side of the film removal mechanism 300. The barcode scanning camera 224 is used to automatically scan and identify markings on the carrier fixture 130 or the components to be peeled. By moving with the material handling module 225, it can accurately align with the markings before or during material handling, quickly reading information such as component model, batch, and specifications, achieving automated material information collection and traceability, and ensuring that the film removal operation matches the specifications of the components to be processed. The quality inspection camera 400 is located on one side of the film removal mechanism 300 and is specifically used for visual quality inspection of the gold fingers after the protective film is peeled off. After the protective film is peeled off, the camera can capture the surface state of the gold fingers through high-definition imaging to identify whether the protective film has been completely removed, ensuring that only qualified gold fingers enter the next process and guaranteeing product quality stability.

[0068] Example 2:

[0069] This embodiment provides a method for tearing tape from gold fingers, which uses the gold finger tape tearing device described in Embodiment 1 to process the gold finger tape, and includes:

[0070] Step S1: After placing the component with the film to be peeled off on the carrier tray, fasten the pressure plate on the carrier tray to fix the component with the film to be peeled off.

[0071] Step S2: Place the tray after the clamping plate is engaged onto the transfer frame for loading;

[0072] Step S3: First, the pressure plate on the carrier tray is adsorbed and transferred by the pressure plate moving assembly to expose the components to be peeled off in the carrier tray. Then, the components to be peeled off are transferred to the film removal mechanism by the component transfer assembly.

[0073] Specifically, step S3 in this embodiment includes:

[0074] Step S31: After the tray moves to the loading station, the tray is stopped by the stop assembly.

[0075] Step S32: Lift the tray using the lifting assembly until it is detached from the transfer frame;

[0076] Step S33: The pressure plate on the carrier tray is adsorbed and transferred by the pressure plate moving assembly to expose the components in the carrier tray whose film is to be peeled off.

[0077] Step S34: Scan and identify the components whose film needs to be removed;

[0078] Step S35: Transfer the components to be peeled off to the film removal mechanism through the component transfer assembly, and at the same time move the empty carrier to the unloading station to receive the components after the film is peeled off.

[0079] Step S4: The protective film of the component to be peeled is held by the film-peeling assembly, and then the film-peeling assembly is moved relative to the component transfer assembly to separate the component and the protective film. During this process, the anti-sticking claw in the recycling assembly moves between the film-peeling assembly and the component transfer assembly and holds at least a portion of the separated protective film.

[0080] Step S5: After the components are completely separated from the protective film, the components with the film removed are placed back into the carrier tray using the component transfer assembly. Simultaneously, the anti-stick grippers are moved above the waste bin, and then the removed protective film is pushed into the waste bin using the film pusher. Specifically, in this embodiment, after the components are completely separated from the protective film, a film removal quality inspection is performed on the components. Then, the components that pass the inspection are placed back into the carrier tray using the component transfer assembly.

[0081] In summary, the gold finger tape peeling device and method described in this invention, through the coordinated operation of a transmission mechanism, a handling mechanism, and a film removal mechanism, constructs a fully automated operation system from the loading and fixing of components to be peeled, the transfer of components to the pressure plate, to the removal and recycling of the protective film. The transmission mechanism achieves stable positioning and transmission of components using a carrier tray and a snap-fit ​​pressure plate; the handling mechanism completes automated transfer through a pressure plate transfer assembly and a component transfer assembly; and the film removal mechanism achieves automated removal and recycling of the protective film. The entire process requires no manual intervention, significantly improving the production efficiency of gold finger tape processing in PCB manufacturing, meeting the high-efficiency requirements of industrial mass production, and also improving the quality of the film peeling process. Compared with conventional tape peeling equipment currently available, this application has advantages such as stable transmission process, high processing accuracy, easy control, high processing efficiency and quality, and wide applicability, providing a new design direction for PCB board processing.
