Abstract
Description
Technical Field
[0001] This disclosure relates to the field of laser peeling equipment technology, and more specifically, to a laser with an adjustable optical path and a laser peeling production line for gold finger protective film. Background Technology
[0002] The gold fingers of a flexible printed circuit board (FPC) are gold-plated conductive terminals on the edges of the FPC, used for signal transmission and electrical connection between electronic devices. During the manufacturing process, a protective film needs to be applied to the gold fingers to prevent scratches or oxidation. This film is peeled off or removed before connecting the ribbon cables. Traditional protective film peeling processes involve machine contact die-cutting followed by manual or machine peeling. Contact die-cutting requires the creation of a die according to the product shape, which not only increases processing costs but also extends the product development cycle. Furthermore, the die needs to be changed according to the product during production, which is time-consuming, labor-intensive, and inefficient.
[0003] The protective film can also be removed by laser ablation. For example, in the laser removal method for waterproof material on the surface of electronic components described in patent CN202011161411.0, the film is removed without causing heat accumulation by using the Coulomb explosion effect generated by an ultrashort pulse laser. This film removal method is highly efficient and low-cost, which helps to reduce product development costs and cycles.
[0004] However, since the lasers on the market generally have high power, there is limited room for reducing the laser power, making them unsuitable for film removal processing. In order to reduce the development cost of the production line, the power of the existing lasers is controlled.
[0005] In addition, considering that laser film removal technology cannot be used interchangeably with existing mechanical film removal production lines, and in order to prevent damage to the terminals after the gold fingers are removed, a production arrangement of peeling and mounting should be implemented. The existing gold finger protective film peeling equipment is not sufficiently automated and does not integrate the mounting station. Therefore, quality problems are easily generated during intermediate transfer, which leads to an increase in the defect rate.
[0006] Therefore, this design proposes a laser peeling production line for gold fingers by modifying the laser by adding a power adjustment optical path, so that the output power of the laser generator is suitable for the film removal process, and designs a gold finger protective film laser peeling production line that can improve the yield of gold fingers.
[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0008] The purpose of this disclosure is to provide a laser with an adjustable optical path and a laser peeling production line for gold finger protective film, thereby overcoming at least to some extent one or more problems caused by the limitations and defects of related technologies.
[0009] According to one aspect of this disclosure, a laser with an added adjustable optical path is provided, including a laser generating device, an adjustable optical path module, and a laser processing head. The adjustable optical path module is added between the output end of the laser generating device and the input end of the laser processing head. The adjustable optical path module includes a beam expander, a beam splitter, a distribution mechanism, an absorption element, and a reflector. The incident light is collimated by the beam expander, and the distribution mechanism drives the beam splitter to rotate and adjust the incident angle of the collimated light, so that the collimated light is distributed by the beam splitter to form a processing optical path and an absorption optical path. The absorption optical path undergoes redundant light absorption processing by the absorption element, and the processing optical path is deflected by the reflector and enters from the input end along the incident optical axis of the laser processing head.
[0010] In one exemplary embodiment of this disclosure, the laser generator and the laser processing head are located on the same side of the adjustment optical path module, the input end and the output end of the adjustment optical path module are located on the same side, and the processing optical path is the refractive optical path of the beam splitter.
[0011] According to another aspect of this disclosure, a laser peeling production line for gold finger protective film is also provided, which includes a laser, a gold finger loading and stacking mechanism, a laser peeling system, a gold finger transport mechanism, a station switching mechanism, a cable mounting system, and a gold finger unloading system. The gold finger transport mechanism transfers the gold fingers automatically loaded from the gold finger loading and stacking mechanism to the laser peeling system. After the laser peeling system completes the film removal process, the gold fingers are transported to the gold finger loading station of the station switching mechanism. The station switching mechanism is sequentially equipped with a gold finger loading station, a cable mounting station, and a gold finger unloading station. The cable mounting system is located on one side of the station switching mechanism, and the gold finger unloading system is located at the end of the station switching mechanism.
[0012] In one exemplary embodiment of this disclosure, the gold finger feeding and stacking mechanism includes a feeding drive mechanism, a stacking tray, a stacking positioning plate, and an air knife. The stacking tray and the stacking positioning plates standing on both sides enclose a placement area for stacking gold fingers. The feeding drive mechanism drives the stacking tray to rise, and the air knife is set at the feeding port of the placement area for blowing air to separate the overlapping gold fingers.
[0013] In one exemplary embodiment of this disclosure, the laser stripping system includes a film removal positioning system, a laser, a film removal platform, an XY track stage, and a gold finger positioning camera. The laser is mounted above the film removal platform, which is movably mounted on the XY track stage. The gold finger positioning camera is mounted on one side of the laser and is fixed to the XY track stage together with the laser. The gold finger is transferred to the film removal platform, and the gold finger positioning camera feeds back the gold finger position information to the film removal positioning system. The film removal positioning system drives the film removal platform to translate and adjust so that the gold finger is aligned with the laser processing head.
[0014] In one exemplary embodiment of this disclosure, the gold fingers are positioned and mounted on a tray. A station switching mechanism is used for the circulation of the tray. It includes a lifting mechanism, an upper conveyor belt, a lower conveyor belt, and a sinking mechanism. The lifting mechanism is located at the gold finger loading station. It lifts the empty tray on the lower conveyor belt to be flush with the upper conveyor belt. After the gold fingers are loaded, it moves the material tray onto the upper conveyor belt. The upper conveyor belt then moves the material tray to the cable mounting station. After mounting, the material tray is moved onto the sinking mechanism. The sinking mechanism is located at the gold finger unloading station. After the gold fingers are unloaded, it moves the empty tray to the lower conveyor belt.
[0015] In one exemplary embodiment of this disclosure, the cable loading system includes a cable loading stacking mechanism, a cable photography and positioning platform, and a cable handling mechanism. The cable handling mechanism sequentially transfers the cables from the cable loading stacking mechanism to the cable photography and positioning platform and the cable mounting station. The positioning information of the cable photography and positioning platform is sent to the cable handling mechanism to position and adjust the position of the cables on the cable handling mechanism.
[0016] In one exemplary embodiment of this disclosure, the gold finger unloading system includes an unloading and conveying mechanism, an unloading and stacking mechanism, and an NG product stacking mechanism. The unloading and conveying mechanism is mounted above the gold finger unloading station and has two mutually perpendicular conveying strokes. One conveying stroke connects the gold finger unloading station and the unloading and stacking mechanism, and the other conveying stroke connects the gold finger unloading station and the NG product stacking mechanism.
[0017] In one exemplary embodiment of this disclosure, a continuity probe testing component is provided in the vacuum suction head of the material handling mechanism. While performing material adsorption and picking up of the gold fingers, the continuity probe testing component is electrically connected to the gold fingers to perform continuity testing and feeds back the continuity test information to the material handling mechanism.
[0018] An exemplary embodiment of this disclosure, which includes a laser with an adjustable optical path and a laser peeling production line for gold finger protective film, has the following beneficial effects:
[0019] The gold finger uses laser to vaporize the protective film, achieving non-contact vaporization film removal with high efficiency and product adaptability. New gold finger products can achieve non-contact peeling of the protective film simply by importing the pattern, without additional cost. The laser used for vaporization film removal is a modification of an existing laser. By adding an adjustment optical path module between the laser generator and the laser processing head, the laser power of the laser generator can be configured according to the film removal power requirements. Redundant light is absorbed by the absorption element. This modification method can optimize the film removal process of the gold finger with minimal investment cost.
[0020] This production line focuses on a fully automated process route for gold fingers, integrating processes such as feeding, transferring, mounting, and unloading of gold fingers and ribbon cables. It has a high degree of intelligence, and the integrated ribbon cable mounting process can enable gold fingers to be peeled and mounted immediately, effectively preventing scratches and damage to the gold finger ports after film removal, and improving the production efficiency and yield of gold finger assembly.

Detailed Implementation
[0028] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.
[0029] This example embodiment provides a laser with an added adjustable optical path, such as... Figure 1 and Figure 3 As shown, an adjustment optical path module 210 is added between the output end of the laser generator 205 and the input end of the laser processing head 220 to the existing laser processing laser. The adjustment optical path module 210 has a closed block structure. In order to make the overall structure of the laser more compact, the input end and the output end of the adjustment optical path module 210 are distributed on the same side. The laser processing head 220 and the laser generator 205 are staggered so that the laser generator 205 and the laser processing head 220 are located on the same side of the adjustment optical path module 210 and are respectively connected to the adjustment optical path module 210.
[0030] The optical path adjustment module 210 includes a beam expander 211, a beam splitter 213, a distribution mechanism, an absorption element 212, and a reflector 214. The incident light from the laser generator 205 is collimated by the beam expander 211 and then enters the beam splitter 213 at a certain incident angle. The beam splitter 213 distributes the incident light into two optical paths through reflection and transmission. The distribution mechanism drives the beam splitter 213 to rotate and adjust, changing the incident angle to adjust the power distribution between the two optical paths. The reflected optical path serves as the processing optical path for the laser film removal process, and it passes through the reflector 214. After being folded 14 times to form the required optical path, the light is incident on the laser processing head 220 from the input end. The laser processing head 220 is equipped with a galvanometer 221 and a field lens 222. After being deflected by the galvanometer 221 and focused by the field lens 222, a processing spot is formed to vaporize and remove the protective film on the gold finger port. The refracted optical path serves as the absorption optical path, which is redundant light. An absorption element 212 is set behind the beam splitter 213 for absorption processing. Multiple reflection absorption elements 212 are set inside the absorption element 212 to eliminate redundant laser light, prevent redundant laser light leakage, and ensure the safety of the machine and personnel.
[0031] This example embodiment also provides a laser peeling production line for gold finger protective film, which is used to realize the automated laser film removal process and integrate the ribbon cable mounting process, so as to realize the gold finger peeling and mounting at the same time, effectively preventing damage to the gold finger port after film removal.
[0032] like Figures 1-2 As shown, the production line includes a gold finger loading and stacking mechanism 100, a laser peeling system 200, a gold finger transport mechanism 300, a station switching mechanism 400, a cable mounting system 500, and a gold finger unloading system 600. The gold finger transport mechanism 300 transfers the gold fingers automatically loaded from the gold finger loading and stacking mechanism 100 to the laser peeling system 200. After the laser peeling system 200 completes the film removal process, it transports the gold fingers to the gold finger loading station 410 of the station switching mechanism 400. The station switching mechanism 400 is sequentially equipped with a gold finger loading station 410, a cable mounting station 420, and a gold finger unloading station 430. The cable mounting system 500 is located on one side of the station switching mechanism 400, and the gold finger unloading system 600 is located at the end of the station switching mechanism 400.
[0033] In an example embodiment, the gold finger feeding and stacking mechanism 100 includes a feeding drive mechanism 101, a stacking tray 103, a stacking positioning plate 102, a material arrival sensor, and an air knife 104. The stacking tray 103 and the two stacking positioning plates 102 standing on its sides together form a material placement area for stacking gold fingers. The stacking positioning plate 102 is provided with an adjustment mechanism to adjust the distance between the two stacking positioning plates 102 to accommodate gold fingers of different sizes. The stacking tray 103 is guided by the vertical stacking positioning plates 102. Under the feeding drive of the feeding drive mechanism 101, the gold fingers in the placement area are pushed out of the feeding port one by one. The material arrival sensor detects that the gold fingers are in place and feeds back to the feeding drive mechanism 101 to stop feeding. In order to prevent the removal of overlapping gold fingers, an air knife 104 is provided on one side of the feeding port. The air knife 104 is supplied with high-pressure air and generates a high-pressure airflow that acts on the end face of the gold fingers, causing the overlapping gold fingers to separate from each other.
[0034] In an example embodiment, the laser stripping system 200 includes a film removal positioning system, a crossbeam, a laser, a film removal platform 202, an XY track stage 201, and a gold finger positioning camera 203. The gold finger positioning camera 203 and the laser are both mounted on the crossbeam, with the gold finger positioning camera 203 located on one side of the laser. The crossbeam is mounted above the film removal platform 202, and its two lower ends are fixedly connected to the XY track stage 201. The film removal positioning system includes two track motors located below the film removal platform 202. A transverse track and a longitudinal track are provided on the XY track stage 201. The gold finger positioning camera 203 sends the collected gold finger position information to the central control system, calculates the adjustment vector, and sends it to the film removal positioning system. The film removal positioning system drives the film removal platform 202 to move slightly along the transverse track and the longitudinal track, so that the gold finger is located directly below the laser processing head.
[0035] In the example embodiment, the gold finger handling mechanism 300 includes a lateral moving mechanism 301, a lifting mechanism 302, and a vacuum suction cup 303. The vacuum suction cup 303 is connected to a vacuum circuit to generate negative pressure to suck up the gold fingers. The vacuum suction cup 303 is located at the lower end of the lifting mechanism 302, which is disposed on the lateral moving mechanism 301. Thus, the vacuum suction cup 303 can perform moving feeding and lifting picking and placing.
[0036] In the example embodiment, the workstation switching mechanism 400 is equipped with trays for positioning and protecting the gold fingers to facilitate the mounting and assembly of the ribbon cable. The three trays are automatically rotated and reused by the workstation switching mechanism 400. Specifically, as shown... Figure 1As shown, the workstation switching mechanism 400 includes a lifting mechanism 401, an upper conveyor belt 403, a lower conveyor belt 402, and a lowering mechanism 404. The cable mounting station 420 is located on the upper conveyor belt 403, and the lower conveyor belt 402 is located directly below the upper conveyor belt 403. The two alternately start to transport the loaded pallet and the empty pallet, respectively. The lifting mechanism 401 and the lowering mechanism 404 have the same structure, and a conveyor belt is installed on them. When the mounting is completed, the lifting mechanism 401 transports the loaded pallet on it to the upper conveyor belt 403, and the upper conveyor belt 403 takes over to transport the loaded pallet. The tray is moved to the cable mounting station 420, and the completed mounting tray is simultaneously conveyed to the sinking mechanism 404. After the gold fingers are unloaded, the lifting mechanism 401 and the sinking mechanism 404 descend simultaneously. The empty tray on the sinking mechanism 404 is transferred to the lower conveyor belt 402, while the previous empty tray on the lower conveyor belt 402 is transferred to the lifting mechanism 401. The lifting mechanism 401 conveys the empty tray to the gold finger loading station 410. At the same time, the sinking mechanism 404 rises back to the gold finger unloading station 430. This cycle continues to achieve the transfer of trays and the processing and loading / unloading of gold fingers.
[0037] In the example embodiment, the cable loading system 500 is used for automatic cable loading. It includes a cable loading and stacking mechanism 503, a cable photo-positioning platform 502, and a cable transport mechanism 501. The structure of the cable loading and stacking mechanism 503 is the same as that of the gold finger loading and stacking mechanism 100, and the structure of the cable transport mechanism 501 is largely the same as that of the gold finger transport mechanism 300. The difference is that a longitudinal moving mechanism is added to the cable transport mechanism 501. The cable transport mechanism 501 picks up the cable from the cable loading and stacking mechanism 503 and moves it longitudinally to the cable photo-positioning platform 502 for photo-positioning. The cable photo-positioning platform 502 takes pictures of the marked points on the cable, and the central control system performs coordinate data calibration and sends a calibration adjustment signal to the cable transport mechanism 501. The cable transport mechanism 501 moves the cable to the cable mounting station 420 and finely adjusts the position of the cable laterally and longitudinally according to the calibration adjustment signal to align the port of the gold finger and lower it to complete the mounting assembly.
[0038] In the example embodiment, the gold finger unloading system 600 can separate the gold fingers from the assembly line based on their conformity after mounting. It includes an unloading and conveying mechanism 601, an unloading and stacking mechanism 602, and an NG (non-conforming) product stacking mechanism 603. The unloading and conveying mechanism 601 has the same structure as the cable handling mechanism 501, and has two mutually perpendicular conveying strokes. The unloading and conveying mechanism 601 is mounted above the gold finger unloading station 430. The unloading and conveying mechanism 601 selects the conveying stroke connecting the gold finger unloading station 430 and the unloading and stacking mechanism 602 to transport conforming products, and selects the conveying stroke connecting the gold finger unloading station 430 and the NG product stacking mechanism 603 to transport non-conforming products. The structures of the unloading and stacking mechanisms 602 and NG product stacking mechanism 603 are similar to those of the gold finger loading and stacking mechanism 100.
[0039] The main qualification test is the continuity test. A continuity probe test component is installed in the vacuum suction head of the unloading and conveying mechanism 601. After the vacuum suction cup 303 adsorbs the gold fingers and the vacuum suction is stable, the continuity probe test component electrically connects the gold fingers to conduct the continuity test. The continuity test information is sent to the central control system for sorting and unloading analysis. The central control system controls the unloading and conveying mechanism 601 to select the corresponding transfer stroke.
