TECHNICAL FIELD
[0001] The application relates to the technical field of PCB processing, and particularly relates to a golden finger adhesive tape tearing device and method. BACKGROUND
[0002] In the field of electronic manufacturing, as the core carrier of electronic components, the automation degree, precision and efficiency of the production and processing process of printed circuit boards (PCB) directly affect the quality and productivity of terminal products. With the increasing demand for miniaturization and high density of PCBs in consumer electronics, automotive electronics and other industries, the processes involved in the PCB processing link, such as golden finger protection, steel sheet cooperation, transfer positioning and quality detection, are facing increasingly severe technical challenges, and the existing processing schemes have gradually been difficult to meet the high precision and high stability requirements of industrialized mass production.
[0003] Specifically, in the PCB incoming material processing scene, the common incoming material form is to move the PCB loaded by a carrier, wherein the golden finger adhesive tape for protecting the golden finger is attached to the bottom of the PCB. However, the existing automatic processing scheme for such incoming materials has the following key technical problems: On the one hand, the tearing and recycling process of the golden finger adhesive tape is low in automation degree and poor in reliability. In most current production lines, the tearing of the golden finger adhesive tape still relies on semi-automatic equipment, which can realize part of the tearing action, but often causes tearing deviation due to PCB board misalignment, thereby damaging the golden finger plating layer. Especially during the transmission process, the PCB board may be misaligned due to the shaking caused by the transmission process, thereby further reducing the film tearing quality. At the same time, the transfer of the PCB between the film tearing and carrier loading processes relies on a single handling mechanism, which not only has difficulty in adapting to different types of products in terms of efficiency and precision, but also is difficult to effectively avoid assembly errors caused by factors such as the slight deviation of the PCB before and after film tearing, the positioning deviation of the carrier itself and the like, thereby resulting in a high rate of defective products.
[0004] On the other hand, the waste adhesive tape recycling link after tearing lacks effective closed-loop processing, and the waste adhesive tape is easy to scatter in the equipment or the production environment, which not only affects the normal operation of the equipment, but also causes subsequent welding short circuit or poor contact of components due to the attachment of residual adhesive debris on the surface of the PCB.
[0005] In summary, in the current PCB processing process, the golden finger adhesive tape processing, steel sheet cooperation, transfer positioning and quality detection links of the incoming material are generally low in automation degree, insufficient in precision, poor in reliability and low in efficiency, and an automatic and high-precision cooperative control technical scheme is urgently needed to solve the defects of the existing technology and meet the needs of industrialized mass production.

[0034] Referring to Figure 3 and Figure 4As shown, the transmission mechanism 100 is used to realize stable conveying and positioning of the components, wherein the transmission frame 110 provides a fixed moving path for the carrier jig 130 through at least one transmission channel 114, ensuring the coherence of the whole film tearing process. In the embodiment, the transmission mechanism 100 further comprises a width adjusting assembly 120, the transmission frame 110 comprises a fixed frame 111 and a moving frame 112, the fixed frame 111 and the moving frame 112 are both provided with a transmission belt 113, and the fixed frame 111 and the moving frame 112 jointly enclose the transmission channel 114, the width adjusting assembly 120 comprises at least one screw rod 121 and a width adjusting driver 122, the screw rod 121 extends along the width direction of the transmission channel 114, one end of the screw rod 121 is fixedly connected to the fixed frame 111, the other end of the screw rod 121 penetrates through the moving frame 112 and threadedly cooperates with the moving frame 112, the width adjusting driver 122 is connected to the screw rod 121 to drive the screw rod 121 to rotate, and the moving frame 112 can move relative to the fixed frame 111 through the screw rod 121 to adjust the width of the transmission channel 114.
[0035] Specifically, in the embodiment, the fixed frame 111 serves as a reference component of the transmission frame 110 to provide stable support for the overall structure, and the transmission belt 113 on the surface of the fixed frame 111 provides one side of the transmission power for the carrier jig 130, while cooperating with the moving frame 112 to form the fixed boundary of the transmission channel 114, ensuring the reference stability when adjusting the width. The moving frame 112 serves as a movable component of the transmission frame 110, and the transmission belt 113 on the surface of the moving frame 112 provides the other side of the transmission power for the carrier jig 130, and can move relative to the fixed frame 111 under the drive of the width adjusting assembly 120 to change the distance from the fixed frame 111, thereby adjusting the width of the transmission channel 114 to adapt to carrier jigs 130 of different sizes. The width adjusting driver 122 provides power output, and drives the screw rod 121 to rotate through structures such as transmission wheels and transmission belts, and the screw rod 121 can convert the rotary motion of the width adjusting driver 122 into the linear motion of the moving frame 112, thereby realizing accurate adjustment of the channel width. Based on the above structure, the transmission mechanism 100 in the embodiment can adapt to components to be torn off film and carrier jigs 130 of different sizes.
[0036] In the embodiment, the accommodation groove on the carrier disc 131 is used for precise placement of the component to be torn off film, and the snap-fit connection between the pressing plate 132 and the carrier disc 131 can firmly fix the component in the accommodation groove, avoiding position deviation caused by vibration and displacement during transmission, providing a stable reference for subsequent film tearing operation, and being especially suitable for positioning needs of precision components such as gold fingers.
[0037] Further, the transmission mechanism 100 in the embodiment further comprises a to-position stop assembly 140 corresponding to the handling station on the transmission channel 114, which comprises a stop driver 141, a stop block 142 and an elastic member 143. The stop driver 141 is arranged 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 handling station through the stop driver 141, and the elastic member 143 is connected to one side of the stop block 142 towards the carrier jig 130 and moves synchronously with the stop driver 141 to stop / avoid the carrier jig 130. The stop driver 141 is installed below the transmission channel 114 as a power source, which realizes the blocking and release control of the carrier jig 130 by driving the stop block 142 to move up and down at the material output end of the handling station, thereby ensuring that the carrier jig 130 accurately stays at the handling station. The stop block 142 moves up and down at the material output end of the handling station under the driving of the driver, and when it rises, it can physically block the carrier jig 130 from continuing to transmit, so that it is accurately positioned at the handling station; when it falls, it completely avoids the carrier jig 130, allowing the carrier jig 130 to pass through, realizing the automatic control of station switching.

[0038] Further, the transmission mechanism 100 in the embodiment further comprises a lifting assembly 150 corresponding to the handling station on the transmission channel 114, which comprises a lifting driver 151 and a lifting frame 152. The lifting driver 151 is arranged below the handling station, and the lifting frame 152 is connected to the working end of the lifting driver 151 to lift the carrier jig 130 in the handling station away from the transmission frame 110. The lifting driver 151 provides driving force for the lifting action of the carrier jig 130 to ensure that the lifting frame 152 stably rises and falls at a predetermined height, which is the power core of the lifting assembly 150. The lifting frame 152 is connected to the working end of the lifting driver 151 and lifts the carrier jig 130 in the handling station upward under the driving of the driver, so that it is separated from the transmission belt 113 on the transmission frame 110. This action can avoid the position deviation of the carrier jig 130 caused by the slight vibration or displacement of the transmission belt 113 when the handling mechanism 200 performs picking and placing operations, provides a stable positioning reference for subsequent operations, eliminates the frictional interference between the transmission mechanism 100 and the carrier jig 130, and ensures the accuracy of picking and placing operations.
[0039] Referring to Figures 5 to 8As shown, the conveying mechanism 200 in the embodiment achieves material transfer between different processes through the cooperation of the press plate transfer assembly 230 and the component transfer assembly 220. Among them, the press plate transfer assembly 230 can accurately adsorb and move away the press plate 132 through the movable press plate transfer frame 232 and multiple press plate suction nozzles 2321, and can release the fixation of the press plate 132 on the component, so as to provide operation space for subsequent material taking and film tearing. After completing the film tearing, the press plate 132 can be re-docked on the carrier disc 131, thereby realizing automatic loading and unloading. The multiple component suction nozzles 2257 on the material taking module 225 adsorb the component to be torn off the film through negative pressure adsorption, which can not only stably grasp the component and transfer it to the film tearing station, but also can maintain the fixed posture of the component during the film tearing process, so as to ensure the stability of the relative position between the protective film and the component, and facilitate the accurate clamping of the film edge by the film tearing assembly 310.
[0040] Further, the conveying mechanism in the embodiment further comprises a support frame 210, the support frame 210 is provided with a first horizontal module 211 and a second horizontal module 212, the first horizontal module 211 and the second horizontal module 212 both extend along the first direction X, the component transfer assembly 220 is slidingly connected to the first horizontal module 211, and the press plate transfer assembly 230 is slidingly connected to the second horizontal module 212.
[0041] Among them, the first horizontal module 211 extends along the first direction X and is slidingly connected with the component transfer assembly 220. On the one hand, it provides a stable guide rail for the component transfer assembly 220, limits its movement only along the first direction X, and ensures that the material taking module 225 can accurately reach the corresponding position of the carrier jig 130. On the other hand, it drives the component transfer assembly 220 to realize smooth and accurate displacement adjustment in the first direction X, so as to meet the taking and placing requirements of different workstations or different specifications of components. The second horizontal module 212 also extends along the first direction X and is slidingly connected with the press plate transfer assembly 230. Its function is similar to that of the first horizontal module 211, and it is specially designed for the press plate transfer assembly 230 to provide guidance and driving in the first direction X, so that the press plate transfer frame 232 can accurately move above the carrier jig 130 to complete the adsorption and transfer operation of the press plate 132. By independently setting the first horizontal module 211 and the second horizontal module 212, the independent movement of the component transfer assembly 220 and the press plate transfer assembly 230 in the same direction can be realized, the mutual interference of the two actions can be avoided, and the conveying efficiency and operation flexibility can be improved.
[0042] In the embodiment, the component transferring assembly 220 comprises a horizontal slide 221, a first lifting module 222 and a lifting slide 223. The horizontal slide 221 is slidingly connected to the first horizontal module 211 and is provided with a third horizontal module 2211 extending along the second direction Y. The first lifting module 222 is slidingly connected to the third horizontal module 2211 and extends along the third direction Z. The lifting slide 223 is slidingly connected to the first lifting module 222, and the material taking module 225 is connected to the lifting slide 223. The pressing plate transferring assembly 230 comprises a second lifting module extending along the third direction Z, and the pressing plate transferring frame 232 is slidingly connected to the second lifting module. Based on the above structure, the pressing plate transferring frame 232 and the material taking module 225 can be flexibly moved respectively.
[0043] Specifically, the material taking module 225 in the embodiment includes an assembly plate 2252, a floating plate 2253, a material pressing driver 2251, a type changing suction plate 2255, and a type changing gripper 2256.

[0044] Referring to Figure 9 and Figure 10As shown, the film removing mechanism 300 in the embodiment can complete the stripping and processing of the protective film by cooperation of the film tearing assembly 310 and the recycling assembly 320. The film tearing assembly 310 can strip the protective film from the component by clamping the edge of the protective film and moving it away from the component, and the protective film is separated from the component by the pulling force, thereby realizing automatic film tearing. The anti-sticking clamping jaw 323 in the recycling assembly 320 can clamp the waste material in time after the protective film is separated from the component, thereby preventing the waste material from being attached to the component or the device due to static electricity or adhesion. The film pushing rod 325 moves in conjunction with the anti-sticking clamping jaw 323, can strip the protective film from the clamping jaw and push it into the waste box 327 below, thereby realizing automatic collection of the waste material, avoiding the influence of the residual protective film on the subsequent process, and maintaining the cleanliness of the device.
[0045] Further, the film removing mechanism 300 further comprises an ion generator 330, which is arranged towards the film tearing assembly 310. The film tearing assembly 310, the ion generator 330 and the anti-sticking clamping jaw 323 are arranged around the waste box 327. The ion generator 330 can generate positive and negative ions to neutralize the static electricity generated by the friction between the protective film and the component during the film tearing process. Since the gold finger and other precision components are sensitive to static electricity, static electricity can cause damage to the components or adsorption of dust and impurities. The ion generator 330 can eliminate static electricity, thereby avoiding the interference of static electricity during the stripping of the protective film, protecting the performance of the components, preventing the protective film from being adhered to the surface of the device or the component due to static electricity, and ensuring smooth film tearing process.
[0046] In the embodiment, the film tearing assembly 310 comprises a film tearing guide rail 311, a moving base 312, a fixed clamping plate 314, a moving clamping plate 315 and a clamping plate driver 313. The film tearing guide rail 311 is arranged on one side of the waste box 327. The moving base 312 is slidingly connected to the film tearing guide rail 311. The fixed clamping plate 314 is arranged on the top of the moving base 312. The clamping plate driver 313 is connected to one side of the moving base 312, and the working end thereof is connected to the moving clamping plate 315 to drive the moving clamping plate 315 to move up and down above the fixed clamping plate 314. The film tearing guide rail 311 provides stable sliding guidance for the moving base 312, limits the movement of the moving base 312 along the preset track, ensures the linearity and accuracy of the film tearing action, and enables the clamping plate to accurately butt joint the protective film. The moving base 312 serves as the mounting carrier of the fixed clamping plate 314, the moving clamping plate 315 and the clamping plate driver 313, and can move along the film tearing guide rail 311 to drive the clamping plate assembly to approach the component to be torn or to move away from the component after clamping the protective film to complete the peeling action. The fixed clamping plate 314 is arranged on the top of the moving base 312 and serves as the fixed reference surface for clamping the protective film. When tearing the film, the fixed clamping plate 314 cooperates with the moving 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 clamping. Correspondingly, the moving clamping plate 315 is connected to the working end of the clamping plate driver 313, and moves up and down above the fixed clamping plate 314 under the driving of the driver. When descending, the moving clamping plate 315 clamps the edge of the protective film together with the fixed clamping plate 314 to provide reliable clamping force. When ascending, the moving clamping plate 315 releases the protective film to facilitate taking, placing or transferring the waste.
[0047] In the embodiment, the recycling assembly 320 comprises a recycling adjustment guide rail 321, a recycling base 322, a clamping jaw driver 324 and a film pushing driver 326. The recycling adjustment guide rail 321 is arranged on one side of the waste box 327. The recycling base 322 is slidingly connected to the recycling adjustment guide rail 321. The clamping jaw driver 324 is arranged on the recycling base 322 and connected to the anti-adhesion clamping jaw 323 to drive the anti-adhesion clamping jaw 323 to move relatively in the third direction Z. The film pushing driver 326 is arranged at one end of the clamping jaw driver 324, and the working end thereof is connected to the film pushing rod 325 to drive the film pushing rod 325 to move towards the waste box 327 along the surface of the anti-adhesion clamping jaw 323.
[0048] The recovery base 322 is slidingly connected to the recovery adjusting guide rail 321, and serves as a mounting carrier of the clamping jaw driver 324, the film pushing driver 326 and the anti-sticking clamping jaw 323. The recovery base 322 drives the entire recovery execution mechanism to adjust the position by moving along the guide rail, so as to realize precise cooperation with the film tearing assembly 310 and ensure that the protective film can be clamped in time after being separated from the component. The clamping jaw driver 324 is mounted on the recovery base 322 and connected to the anti-sticking clamping jaw 323, and provides the anti-sticking clamping jaw 323 with opening and closing driving force in the third direction Z. The film pushing driver 326 is arranged at one end of the clamping jaw driver 324 and connected to the film pushing rod 325, and provides the film pushing rod 325 with moving force in the direction of the surface of the anti-sticking clamping jaw 323 towards the waste box 327. The film pushing rod 325 drives the anti-sticking clamping jaw 323 to strip the protective film clamped thereon and push the protective film into the waste box 327, so as to complete automatic waste treatment and avoid the protective film remaining on the clamping jaw to affect subsequent recovery actions.
[0049] Further, the suction port at the bottom of the waste box 327 in the embodiment forms a negative pressure environment through external suction equipment. When the film pushing rod 325 pushes the protective film into the waste box 327, the suction force generated by the suction port can quickly adsorb the floating protective film to the bottom of the waste box 327, so as to avoid the floating, accumulation at the box opening or rebound overflow of the protective film due to static electricity, air flow or its own elasticity.
[0050] Further, the layout design of the film tearing assembly 310, the ion generator 330 and the anti-sticking clamping jaw 323 arranged around the waste box 327 in the embodiment can form a compact and efficient film removing operation unit. Such a layout enables the protective film stripped by the film tearing assembly 310 to be clamped by the anti-sticking clamping jaw 323 in a short distance, reduces the floating time of the protective film in the air, and enables the ion generator 330 to directly act on the film tearing area and the protective film transfer path, so as to maximize the effect of static electricity neutralization. At the same time, the anti-sticking clamping jaw 323 is close to the waste box 327, so that the film pushing rod 325 can quickly push the protective film into the waste box 327, shorten the waste treatment path, improve the overall film removing efficiency, and reduce the space occupation.
[0051] The embodiment also includes a code scanning detection camera 224 connected to the component transfer assembly 220 and moving synchronously with the component taking module 225, and a quality detection camera 400 arranged on one side of the film removing mechanism 300. The code scanning detection camera 224 is used to automatically scan and identify the identification on the carrier 130 or the component to be film-removed. By moving with the component taking module 225, the identification position can be accurately aligned before or during taking, and the component model, batch, specification and other information can be quickly read, so as to realize automatic acquisition and tracing of material information and ensure that the film-removing operation is matched with the specification of the component to be processed. The quality detection camera 400 arranged on one side of the film removing mechanism 300 is specially used for appearance quality detection of the gold finger after film removal. After the protective film is peeled off, the camera can capture the surface state of the gold finger through high-definition imaging, identify whether the protective film has been completely removed, and ensure that only qualified gold fingers enter the next process, thereby ensuring product quality stability.
