Description

Technical Field

[0001] This invention relates to the field of electronic product structural component processing technology, and in particular to an automated adhesive removal device for card trays. Background Technology

[0002] Card trays (such as SIM card trays and memory card trays) are core precision components of electronic devices. After the waterproof sealing process, they typically undergo three key stages: "material loading, adhesive removal (removing residual liquid waterproof silicone), and quality inspection (inspecting the adhesive removal effect and appearance defects)." In existing technologies, these three stages are usually completed by independent equipment, which has the following drawbacks: Material loading relies on manual labor or a single mechanism, resulting in low efficiency (5-10 seconds per card tray) and easy contamination. Traditional material loading mechanisms (such as vibratory feeders) cannot adapt to the multi-positional requirements of card trays (such as curved surfaces and irregular edges), leading to a low success rate. Adhesive removal and quality inspection are separated, requiring manual transfer of card trays between the adhesive removal equipment and the quality inspection equipment, causing process interruptions (transfer time of 3-5 seconds per tray). Furthermore, the adhesive removal effect cannot be fed back in real time, resulting in a high rate of missed inspections. The equipment in each stage is controlled independently, making it impossible to adjust parameters in a coordinated manner (such as mismatch between the adhesive removal mode and the quality inspection standards), leading to low overall efficiency and large fluctuations in yield.

[0003] To address the aforementioned issues, some existing technologies have been improved. For example, Chinese patent application CN120479817A discloses a fully automatic adhesive removal device for mobile phone SIM card tray production, including a turret section, an adhesive removal section, and a feeding section. The turret section includes a rotating disk, a rotating pneumatic gripper, and a rotating clamp. The rotating disk drives the rotating pneumatic gripper and the rotating clamp to rotate. The adhesive removal section includes a first brush, a second brush, and a third brush, which remove adhesive from the two short sides and two long sides of the SIM card tray, respectively. This solution achieves automated adhesive removal for the SIM card tray, but it only involves the single process of adhesive removal. The feeding process still requires manual labor or auxiliary mechanisms. It lacks a detection station for the adhesive removal effect, making it impossible to verify the cleaning quality in real time during the cleaning process, resulting in limited overall automation.

[0004] Chinese patent CN216883721U discloses an automatic card tray ring-fitting machine, including a card tray conveying assembly, a rubber ring conveying assembly, and a rubber ring fitting assembly. The card tray conveying assembly has a vision inspection component for detecting the rubber ring fitting status and a defect removal component for pushing and collecting card trays with defective rubber rings off the conveying assembly. The vision inspection component includes a CCD camera and a detection processor. Although this solution integrates vision inspection functionality, it only processes the card tray rubber ring fitting process, not the rubber cleaning process, and it lacks an automatic feeding mechanism and a rubber cleaning mechanism, thus failing to solve the automation problem in the card tray rubber cleaning operation.

[0005] Chinese patent application CN122231009A discloses a device for cleaning residual adhesive from mobile phone side buttons, including a frame and a worktable on it. A turntable mechanism is installed on the worktable, and multiple clamping fixtures are arranged in a circular array on the turntable. A pressing mechanism, an adhesive cleaning mechanism, a visual inspection mechanism, and a material handling mechanism are sequentially arranged along the circumference of the turntable. The turntable drives the clamping fixtures through each station in sequence, realizing continuous operation of automatic feeding, pressing, adhesive cleaning, inspection, and sorting of mobile phone side buttons. Although this solution integrates feeding, adhesive cleaning, and inspection functions, its processing object is mobile phone side buttons rather than SIM card trays, and the feeding mechanism uses a traditional feeding method, lacking flexible adaptability to multi-pose SIM card trays, and cannot meet the precise gripping requirements of irregularly shaped edges and curved surfaces in SIM card tray production.

[0006] In addition, although there are existing technologies that combine spider arms with CCD vision inspection for sorting, they do not involve the adhesive removal process and cannot solve the technical problem of removing residual adhesive from the waterproof silicone of the card tray.

[0007] In summary, while existing technologies include automated adhesive removal equipment using rotary table structures and solutions combining spider-handled tools with CCD vision inspection for sorting or loading, they all suffer from the following shortcomings: They lack a fully integrated, end-to-end system that combines automated spider-handled loading, liquid waterproof silicone adhesive removal, and CCD vision self-inspection; existing adhesive removal equipment relies on manual labor or traditional mechanisms for loading, failing to adapt to the multi-positional requirements of card trays, resulting in low loading success rates; adhesive removal and quality inspection are separated, requiring manual transfer of card trays, leading to process interruptions; the adhesive removal effect cannot be fed back in real time, resulting in a high rate of missed detections; and each stage of the equipment is controlled independently, making parameter adjustments impossible and overall coordination poor. Therefore, this invention discloses an automated adhesive removal device for card trays to solve these problems. Summary of the Invention

[0008] Based on this, it is necessary to provide an automated card tray cleaning equipment to address the aforementioned technical problems. This equipment uses a clamping fixture that rotates with the indexing rotary table, sequentially passing through the feeding, pushing, cleaning, inspection, and unloading stations to form a fully integrated closed-loop production line. This significantly improves production efficiency and achieves flexible, adaptive clamping, ensuring stable card tray position during high-speed operation. It can adapt to various card tray specifications, simplifies the structure, and ensures strict synchronization between opening and closing actions and the rotation cycle, eliminating feeding and placement deviations and guaranteeing consistent positioning height before cleaning. This significantly improves the consistency of cleaning quality and yield rate.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automated adhesive removal device for card trays includes a machine body with a worktable on the machine body. The worktable has a fixed plate and an indexing rotary plate arranged coaxially. The indexing rotary plate has a plurality of clamping fixtures arranged in a circular array along the circumference. The indexing rotary plate drives the clamping fixtures to pass through a loading station, a pushing station, an adhesive removal station, an inspection station, and an unloading station in sequence, thereby realizing the loading, positioning, adhesive removal, appearance inspection, and unloading of card trays. The clamping fixture includes a base fixed on an indexing rotary table, two sets of symmetrically arranged jaws are slidably connected on the base and a first spring is connected between the two jaws, and an adjustment component is slidably provided on one side of the base, the adjustment component being used to adjust the distance between the two positioning jaws; The fixed plate is located at the loading station and the unloading station and is equipped with a displacement structure for driving the adjustment component to move; The feeding station is equipped with a feeding structure, which is used to push the tray placed on the clamping fixture at the feeding station into place.

[0010] In a preferred embodiment of the automated adhesive removal equipment for card trays provided by the present invention, the workbench is provided with a feeding mechanism at the feeding station. The feeding mechanism includes a flexible vibrating plate and a spider manipulator with a vacuum suction head. The vacuum suction head on the spider manipulator adsorbs the card trays on the flexible vibrating plate and moves them between two grippers. The displacement structure pushes the adjustment component to move, so that the two grippers fix the card trays.

[0011] In a preferred embodiment of the automated adhesive removal device for card trays provided by the present invention, the inner front end of the two grippers is provided with a clamping groove, and the lower end wall of the clamping groove extends to form a support base plate, which is used to support both ends of the card tray.

[0012] As a preferred embodiment of the automated glue removal equipment for the card tray provided by the present invention, there are two glue removal stations, and each glue removal station is provided with a set of glue removal components. The glue removal components include a lifting frame and two sets of motor-driven glue removal brushes. During glue removal, the two glue removal brushes are located on both sides of the card tray.

[0013] As a preferred embodiment of the automated adhesive removal equipment for the card tray provided by the present invention, the adhesive removal assembly includes a lifting frame and two sets of motor-driven adhesive removal brushes, and a telescopic cylinder is fixed on the lifting frame. The output end of the telescopic cylinder is fixed with a vertical plate with a positioning groove, and the positioning groove of the vertical plate matches the card tray.

[0014] In a preferred embodiment of the automated adhesive removal equipment for Cato provided by the present invention, a waste collection box is further provided below the adhesive removal brush. The waste collection box is connected to an external industrial dust collector via a flexible air duct, and an electrostatic elimination device is provided inside the waste collection box. As a preferred embodiment of the automated adhesive removal equipment for card trays provided by the present invention, the inspection station is provided with three stations, each equipped with a vision inspection structure. The vision inspection structures of the three stations respectively perform visual inspection on the two sides, the upper surface and the lower surface of the card tray after adhesive removal.

[0015] In a preferred embodiment of the automated adhesive removal device for the cardoter provided by the present invention, the adjustment assembly includes an adjustment seat with a slider, a slide rail fixed on the clamping fixture, the adjustment seat sliding along the slide rail, two sets of adjustable spacing positioning strips on the adjustment seat, and adjusting rollers on both jaws. When the adjustment assembly moves, the two positioning strips abut against the adjusting rollers to adjust the distance between the two jaws. Adjusting screws for adjusting the spacing of the positioning strips are provided at both ends of the adjustment seat. End blocks are fixed at both ends of the slide rail, and magnets are embedded in the end blocks for attracting and fixing the adjustment seat.

[0016] In a preferred embodiment of the automated adhesive removal equipment for the cardoter provided by the present invention, a protrusion is fixed on the top surface of the adjusting seat, and the shifting structure is fixed at the loading and unloading positions of the platen. The shifting structure is driven by a cylinder to push or pull the protrusion, thereby causing the adjusting seat to move back and forth.

[0017] In a preferred embodiment of the automated adhesive removal equipment for cassettes provided by the present invention, there are two unloading stations, and each unloading station is provided with a guide channel, which is a qualified channel and an unqualified channel respectively.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The automated adhesive removal equipment for cassettes provided by this invention features a coaxially aligned fixed plate and an indexing rotary plate. Multiple clamping fixtures are arranged in a circular array on the indexing rotary plate. These fixtures sequentially pass through the feeding, pushing, adhesive removal, inspection, and unloading stations as the rotary plate rotates, forming a fully integrated closed-loop production line. This eliminates the manual transfer interruptions caused by the separation of adhesive removal and quality inspection in traditional methods, avoids secondary contamination, and significantly improves production efficiency. Flexible adaptive clamping is achieved by sliding two sets of symmetrically arranged grippers on the base and connecting them to a first spring, along with adjusting components and a shifting structure. To avoid damage to curved or irregularly shaped edge clamps, ensure stable clamp position during high-speed operation, and easily adjust the clamp spacing to accommodate various clamp specifications, the equipment's versatility is improved and changeover costs are reduced. The opening and closing of the clamps are controlled automatically, eliminating the need for a separate power source for each clamping fixture. This simplifies the structure and ensures that the opening and closing actions are strictly synchronized with the rotation rhythm. By setting a push station between the feeding and cleaning stations, the clamps are precisely pushed to the standard clamping position using a push structure, eliminating feeding placement deviations and ensuring consistent positioning height before cleaning, thereby significantly improving the consistency of cleaning quality and yield.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Please refer to Figures 1-8 This invention provides an automated adhesive removal device for card trays, comprising a body 1 containing a PLC control system. The PLC control system employs a conventional control system. The body 1 has a worktable 2, on which a fixed plate 3 and an indexing rotary plate 4 are coaxially arranged. The indexing rotary plate 4 rotates intermittently via a divider or servo drive. The indexing rotary plate 4 has several clamping fixtures 5 arranged in a circular array along its circumference. The indexing rotary plate 4 drives the clamping fixtures 5 sequentially through a loading station A, a pushing station B, an adhesive removal station C, a detection station D, and an unloading station E, thus removing the adhesive from the card tray. The machine has a loading, positioning, degumming, appearance inspection, and unloading station, all of which are arranged on the surface of the workbench 2. Each station is located inside the machine cover, which is fixed on the workbench 2. The PLC control system is electrically connected to the drive mechanism of the indexing rotary table 4, the actuators of each station, and the vision inspection structure 10. It is used to control the intermittent rotation rhythm of the indexing rotary table 4 and the timing coordination and linkage of the actions of each station. The operator can set parameters such as the rotation speed of the indexing rotary table 4, the degumming time and speed of the degumming component 9, and the judgment threshold of the vision inspection through the human-machine interface, so as to realize the centralized control and real-time adjustment of the machine's operating parameters.

[0027] like Figures 3-5As shown, in this embodiment, the clamping fixture 5 includes a base 51 fixed on the indexing rotary table 4. Stops 52 are provided at both ends of the base 51. Two sets of symmetrically arranged grippers 53 are slidably connected to the base 51, and a first spring 54 connects the two grippers 53. An adjustment component 55 is slidably provided on one side of the base 51. The adjustment component 55 is used to adjust the distance between the two grippers 53. The fixed plate 3 is located at the loading station A and unloading station E, and is equipped with a shifting structure 6 for moving the adjustment component 55. The pushing station B is equipped with a pushing structure 7, which is a multi-stage... The active correction and feeding mechanism includes a laser displacement sensor and a universal correction head driven by a stepper motor. The feeding structure 7 is used to push the tray placed on the clamping fixture 5 at the loading station A into place, ensuring accurate positioning of the tray. The feeding structure 7 includes a feeding cylinder fixed on the worktable 2 and a push rod connected to the output end of the feeding cylinder. The end of the push rod is provided with a flexible buffer head. When feeding, the flexible buffer head abuts against the tray and pushes it to the preset positioning reference surface. The stroke of the feeding cylinder is set and controlled by the PLC control system according to the tray specifications. A laser displacement sensor is used to detect the actual position and orientation of the card tray on the clamping fixture 5 (including X-axis offset, Y-axis offset, and angular deflection). The PLC control system calculates the compensation amount based on the detection data and controls the universal correction head to push the card tray at a specific angle and force, accurately correcting the card tray to the standard clamping position. After correction, the shifting structure 6 pushes the adjusting component 55 to clamp the card tray with the gripper 53. Through this design, "passive pushing" is upgraded to "active correction pushing," fundamentally eliminating material placement deviation and ensuring that the positioning accuracy before glue removal can reach ±0.02mm. like Figures 1-5As shown, further, the workbench 2 is equipped with a feeding mechanism 8 at the feeding station A. The feeding mechanism 8 includes a flexible vibratory feeder 81 and a spider robot 82 with a vacuum suction head 83. During feeding, the vacuum suction head 83 on the spider robot 82 adsorbs the card tray on the flexible vibratory feeder 81 and, after visual positioning, moves it between two grippers 53. The shifting structure 6 pushes the adjustment component 55 to move, so that the two grippers 53 fix the card tray. The flexible vibratory feeder 81 has a built-in vibration frequency regulator to control the output speed and arrangement posture of the card tray. The spider robot 82 is equipped with an independent visual guidance system. This system collects the position and angle information of the card tray on the flexible vibratory feeder 81 through an industrial camera, as shown in the figure. After processing, the spider robot 82 is guided to grasp the card tray in a compensated posture, ensuring that the card tray is accurately placed in the predetermined position between the two grippers 53. A posture pre-adjustment platform is set between the discharge port of the flexible vibrating plate 81 and the grasping position of the spider robot 82. After the card tray is discharged from the flexible vibrating plate 81, it first falls on the posture pre-adjustment platform. The pneumatic pin or vision-guided micro-adjustment claw set above the platform pre-aligns the card tray according to the posture of the card tray recognized by the vision system. After pre-alignment, the card tray is then grasped by the spider robot 82 and transferred to the clamping fixture 5. Through the two-stage strategy of pre-adjustment and fine grasping, the accuracy requirements of the single link of the spider robot 82 are reduced, and the loading success rate is improved. Furthermore, the inner side of the front end of the two grippers 53 is provided with a gripping groove 531, and the lower end wall of the gripping groove 531 extends to form a support base plate 532. The support base plate 532 is used to support the two ends of the card tray. Under the action of the first spring 54, the two grippers 53 are initially far apart from each other. When the card tray is placed at the front end of the two grippers 53, the support base plate 532 supports the two ends of the card tray. After the shifting structure 6 pushes the adjusting component 55 to move, the adjusting component 55 acts on the two grippers 53 and makes the two grippers 53 move closer to each other. The two ends of the card tray extend into the gripping groove 531, thereby flexibly clamping and fixing the card tray. The inner wall of the gripping groove 531 and the upper surface of the support base plate 532 are provided with an anti-slip coating to increase the friction with the contact surface of the card tray and prevent the card tray from sliding or shifting during high-speed rotation. The entrance of the gripping groove 531 is provided with a guide chamfer to facilitate the smooth introduction of the end of the card tray into the gripping groove 531.

[0028] like Figure 2 , Figure 7As shown, furthermore, there are two glue removal stations C, each equipped with a set of glue removal components 9. Each glue removal component 9 includes a lifting frame 91 and two sets of glue removal brushes 92 driven by motors 93. A telescopic cylinder 94 is also fixed on the lifting frame 91. A vertical plate 95 with a positioning groove is fixed to the output end of the telescopic cylinder 94. A flexible rubber pad is provided on the inner wall of the positioning groove to avoid damage to the card holder. During glue removal, the telescopic cylinder 94 drives the vertical plate to move, and the front end of the card holder is inserted into the positioning groove. To achieve the purpose of positioning the card tray and ensure stability during the cleaning process, two cleaning brushes 92 are located on both sides of the card tray. When the clamping fixture 5 holds the card tray and rotates to the cleaning position C, the two sets of cleaning components 9, driven by cylinders, hydraulic cylinders, and other components, drive the lifting frame 91 to rise, so that the two cleaning brushes 92 are located on both sides of the card tray. Driven by the motor 93, the cleaning brushes 92 rotate to clean the card tray. The bristles of the cleaning brushes 92 are made of wear-resistant nylon or rubber containing abrasive particles. The two sets of cleaning brushes 92 rotate in opposite directions, and the rotation speed of the cleaning brushes 92 and the rising height of the lifting frame 91 are both set by the PLC control system according to the material of the card tray and the thickness of the residual glue. Different cleaning parameters can be set for the two cleaning stations C to perform differentiated cleaning treatment on different areas of the card tray. A waste collection box 96 is also set below the cleaning brushes 92 to collect the cleaned residual glue. The waste collection box 96 is connected to an industrial dust collector outside the equipment through a flexible air duct. During the cleaning process, the negative pressure system works continuously to suck away the cleaned residual glue debris in time. A wind speed sensor is installed at the inlet of the waste collection box 96 to monitor whether the negative pressure is normal and to alarm when abnormal. The waste collection box 96 is equipped with an electrostatic elimination device, such as an ion bar, to eliminate the static electricity generated by friction during the cleaning process and prevent residual glue debris from being attracted to the surface of the card tray or inside the equipment due to static electricity. Through this design, the cleanliness of the cleaning and the operating environment of the equipment are significantly improved.

[0029] like Figure 2 , Figure 3As shown, furthermore, there are three inspection stations D, arranged sequentially. Each inspection station D is equipped with a vision inspection structure 10. The three vision inspection structures 10 are independently configured according to the area to be inspected. The vision inspection structures 10 are used to detect whether the residual adhesive on the surface of the card tray has been thoroughly removed. Specifically, the vision inspection structures 10 of the three inspection stations D respectively perform visual inspection on the two sides, the upper surface, and the lower surface of the card tray after adhesive removal. Each vision inspection structure 10 includes a CCD industrial camera, a coaxial light source or a ring light source, and an image processing module. The three vision inspection structures 10 surround the clamping fixture 5. The different angles of the workstations are fixedly installed on the workbench 2. The image processing module has pre-stored standard images and residual glue tolerance thresholds for each surface of the card tray. During inspection, the CCD industrial camera acquires real-time images of the corresponding surface of the card tray and compares them with the standard images. Areas exceeding the tolerance threshold are marked as defective. The inspection results of the three vision inspection structures 10 are summarized to the PLC control system. The PLC control system controls the sorting action of the subsequent unloading station E according to the comprehensive judgment result. In addition, the PLC control system can adjust the glue removal parameters of the glue removal station C in real time according to the feedback results of vision inspection, forming a closed-loop quality control.

[0030] like Figures 4-6 As shown, the adjustment assembly 55 further includes an adjustment seat 551 with a slider, a slide rail 552 fixed on the clamping fixture 5, the adjustment seat 551 sliding along the slide rail 552, the adjustment seat 551 having two sets of adjustable spacing positioning strips 553, and each of the two grippers 53 having an adjusting roller 533. The inner side of the end of the positioning strip 553 near the adjusting roller 533 is set as an arc slope to facilitate smooth pressure on the adjusting roller 533. When the adjustment assembly 55 moves, the two positioning strips 553 fit against the adjusting roller 533 to adjust the distance between the two grippers 53. When the shifting structure 6 pushes the adjustment seat 551, the two positioning strips 553 press on the adjusting roller 533, thereby driving the two grippers 53 to move closer to each other until the grippers 53 clamp the tray. Furthermore, both ends of the adjusting seat 551 are equipped with adjusting screws 554 for adjusting the spacing between the positioning strips 553. By rotating the adjusting screws 554, the positioning strips 553 can slide along the adjusting seat 551 to adjust the spacing between the two positioning strips 553, thereby adapting to clamping clips of different widths. Of course, the adjusting screws 554 can also be equipped with locking nuts to lock the positioning strips 553 after the position of the positioning strips 553 is adjusted, preventing the positioning strips 553 from shifting due to vibration during equipment operation.

[0031] like Figure 2 , Figure 3 and Figure 6 , Figure 8As shown, furthermore, end blocks 555 are fixed at both ends of the slide rail 552, and magnets 556 are embedded in the end blocks 555. The magnets 556 are used to attract and fix the adjusting seat 551. During loading, the displacement structure 6 at the loading station A pushes the adjusting seat 551 to fit against the end block 555 at the front end. Under the attraction of the magnets 556, the adjusting seat 551 is fixed. During unloading, the displacement structure 6 at the unloading station E pulls the adjusting seat 551, so that the adjusting seat 551 fits against the end block 555 at the rear end. The two grippers 53 move away from each other under the action of the first spring 54, thereby releasing the clamp. Specifically, a protrusion 557 is fixed on the top surface of the adjusting seat 551. The displacement structure 6 is fixed to the fixed plate 3 located at the loading station A and the unloading station E. Positioning structure 6 uses a cylinder to drive the push or pull of the protrusion 557, thereby causing the adjusting seat 551 to move back and forth. The cylinder of the positioning structure 6 is equipped with a stroke sensor switch to detect whether the adjusting seat 551 has moved into place and to feed the signal back to the PLC control system to ensure that the gripper 53 can reliably clamp or release the card tray. There are two unloading stations E, and each unloading station E is equipped with a guide channel 11. The two guide channels 11 are respectively the qualified channel and the unqualified channel. The visual inspection structure 10 of the inspection station D visually inspects the card tray after the glue is removed. The qualified card tray falls from the qualified channel, and the unqualified card tray falls from the unqualified channel. A collection box is provided below the guide channel 11 to collect qualified and unqualified products respectively.

[0032] In this embodiment, the clamping fixture 5, the adhesive removal brush 92, and the vision inspection structure 10 are all modular quick-change structures. The clamping fixture 5 can be quickly disassembled and replaced, with different sizes of trays corresponding to different clamping fixture modules. The adhesive removal brush 92 uses a quick-connect connector, allowing replacement within one minute. Each module is equipped with an electronic tag (RFID). The equipment automatically identifies the module model and loads the corresponding working parameters by reading the electronic tag. The changeover time is no more than 5 minutes. Through the modular quick-change design, the equipment is upgraded from a "dedicated machine" to a "general-purpose platform," greatly improving the return on investment and the scope of application of the equipment. It is worth noting that several sensors, such as proximity switch sensors, are also installed on the overall equipment to locate the adjustment positions of each adjustment component in real time, ensuring positional accuracy. This part is conventional technology, and the sensor settings are determined according to the specific application, so it will not be described in detail here.

[0033] The working principle of the automated adhesive removal equipment for cassettes provided by this invention: After the equipment is started, the PLC control system coordinates the orderly actions of each station according to the preset program. The indexing rotary table 4 rotates intermittently under the drive of the divider or servo drive mechanism, driving the multiple clamping fixtures 5 arranged in a ring array on it to pass through the loading station A, the pushing station B, the glue removal station C, the inspection station D and the unloading station E in sequence.

[0034] At loading station A, the flexible vibratory feeder 81 disperses the accumulated card trays in an orderly manner through vibration. The spider robot 82 uses its independent vision guidance system to locate and identify the card trays scattered in the discharge area of ​​the flexible vibratory feeder 81. Then, it uses a vacuum suction head 83 to pick up the card trays and accurately transfers them to the support base plate 532 at the front end of the two grippers 53 of the clamping fixture 5 according to the visually compensated motion trajectory. At this time, the cylinder of the shifting structure 6 on the fixed plate 3 located at loading station A extends and pushes the protrusion 557 of the adjusting seat 551, causing the adjusting seat 551 to slide along the slide rail 552. The arc slope of the two sets of positioning strips 553 on the adjusting seat 551 synchronously abuts against the adjusting rollers 533 on the two grippers 53, overcoming the force of the first spring 54 and bringing the two grippers 53 closer to each other until the two ends of the card tray are inserted into the clamping groove 531, achieving flexible clamping and fixing. Then, the magnet 556 attracts and fixes the adjusting seat 551 to maintain the clamping state.

[0035] The indexing rotary table 4 rotates one station, and the clamping fixture 5 holding the card tray enters the pushing station B. The pushing cylinder in the pushing structure 7 extends, and the flexible buffer head at the front end of the push rod abuts against the card tray, pushing the card tray further to the positioning reference surface to ensure the consistency of the card tray's position within the clamping fixture 5.

[0036] The indexing rotary table 4 continues to rotate, and the clamping fixture 5 passes through two glue removal stations C in sequence. At each glue removal station C, the lifting frame 91 rises under the drive of the cylinder, so that the two sets of glue removal brushes 92 are located on both sides of the card tray. The two sets of glue removal brushes 92 rotate in opposite directions under the drive of the motor 93 to remove residual glue from the corresponding surface of the card tray. Different glue removal parameters can be set for the two glue removal stations C as needed to achieve differentiated glue removal.

[0037] After the adhesive removal is completed, the clamping fixture 5 enters the three inspection stations D in sequence. The three inspection stations D perform visual inspection on the two sides, the upper surface and the lower surface of the card tray from different angles. The CCD industrial camera at each station, together with the light source, collects real-time images of the corresponding surface of the card tray. The image processing module compares and analyzes the collected images with the pre-stored standard images to determine whether there is residual adhesive or other appearance defects. The inspection results are uploaded to the PLC control system in real time.

[0038] Finally, the clamping fixture 5 rotates to the unloading station E. Based on the comprehensive judgment results of the three detection stations D, the PLC control system controls the cylinder of the shifting structure 6 of the unloading station E to pull the adjusting seat 551, so that the adjusting seat 551 is disengaged from the magnet 556 and slides to the rear end block 555. Under the action of the first spring 54, the two grippers 53 move away from each other and open up, releasing the card tray. Qualified products fall into the qualified channel, and unqualified products fall into the unqualified channel, which are collected by the corresponding collection boxes, completing the fully automated operation.

[0039] This invention features a coaxially aligned fixed plate 3 and indexing rotary plate 4, with multiple clamping fixtures 5 arranged in a circular array on the indexing rotary plate 4. The clamping fixtures 5 rotate with the indexing rotary plate 4, sequentially passing through loading station A, pushing station B, adhesive removal station C, inspection station D, and unloading station E, forming a fully integrated closed-loop production line. This eliminates the manual transfer interruptions caused by the separation of adhesive removal and quality inspection in traditional methods, avoids secondary contamination, and significantly improves production efficiency. Two sets of symmetrically arranged grippers 53 are slidably connected to the base 51 and connected to a first spring 54. Combined with the adjustment component 55 and the shifting structure 6, flexible adaptive clamping is achieved, preventing damage to curved or irregularly shaped edge holders and ensuring stable holder position during high-speed operation. The spacing between the grippers 53 can be easily adjusted to accommodate various holder specifications, improving equipment versatility and reducing changeover costs. Simultaneously, the shifting structure 6 on the fixed plate 3 dynamically controls the opening and closing of the grippers 53, eliminating the need for separate equipment for each clamping fixture 5. The power source simplifies the structure and ensures strict synchronization between opening and closing actions and rotation rhythm. By setting up a pushing station B between the loading station A and the cleaning station C, the pushing structure 7 accurately pushes the card tray to the standard clamping position, eliminating loading placement deviations and ensuring consistent positioning height before cleaning. This significantly improves the consistency of cleaning quality and yield. By setting up two cleaning stations C and configuring cleaning components 9 with independently adjustable speed and lifting height, differentiated cleaning treatment of different areas of the card tray is achieved. Combined with three detection stations D for full-coverage visual inspection of the card tray's sides, upper surface, and lower surface, a closed-loop quality control system of cleaning-inspection-feedback is constructed. The PLC control system can adjust the cleaning parameters in real time according to the detection results, effectively reducing the missed detection rate and false detection rate. By setting up two unloading stations E and configuring qualified and unqualified channels, the products are automatically sorted online according to the judgment results of the PLC control system, further improving the automation level and output yield of the equipment.
