Description

Technical Field

[0001] This invention provides an automated feeding, film-tearing, and framing device, specifically relating to the field of automated equipment. Background Technology

[0002] This invention relates to the field of automated processing equipment technology, specifically to an automated feeding, film-removing, and framing equipment for thin-film products, such as protective films for electronic components, optical films, and display screen assemblies.

[0003] In industries such as electronics manufacturing and optical device processing, the production process for thin-film products typically includes the core steps of "material loading - film removal - framing". These products are characterized by their thinness, fragility, and diverse specifications, demanding extremely high precision, stability, and automation in the processing. Currently, the processing methods on the market are mainly divided into manual operation and semi-automated equipment processing, both of which have significant drawbacks: high human involvement, low processing efficiency, and unstable quality. In traditional processing, material loading requires manual stacking of products, film removal relies on manual peeling or simple tools, and framing requires manual alignment and positioning. This not only results in high labor intensity and low production efficiency but also easily leads to product scratches, incomplete film removal, and frame misalignment due to human error, severely impacting product yield. Semi-automated equipment suffers from poor coordination and fragmented functionality. Existing semi-automated equipment is mostly designed with independent single processes (such as separate deployment of feeding machines, film-tearing machines, and framing machines), lacking unified collaborative control between these devices. Manual product transfer is required, resulting in gaps in process connections. Furthermore, in the film-tearing process, the tape feeding often uses ordinary rollers, lacking stable tension adjustment and directional traction structures, making the tape prone to loosening and shifting, leading to asynchronous double-sided film tearing and protective film residue. Waste film recycling is mostly done through open collection, easily causing a messy workshop environment and potentially entangled equipment, affecting operation. Equipment adaptability is insufficient, and changeover costs are high. The existing equipment's hopper size, film-tearing roller spacing, and framing positioning structure are mostly fixed designs, making it difficult to quickly adapt to products of different widths and thicknesses. When production specifications change, disassembly and adjustment of the mechanical structure are required, which is time-consuming and labor-intensive, failing to meet the needs of multi-variety, small-batch production. Therefore, existing processing methods can no longer meet the demands of large-scale, high-precision production. There is an urgent need for an integrated, highly automated, stable feeding, precise film tearing, flexible adaptation, and safe and controllable integrated equipment to solve the above-mentioned technical pain points. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated intelligent device that is compatible with most specifications and models in the industry and can be intelligently and quickly changed and put into production without changing fixtures, effectively solving the related technical problems raised in the background.

[0005] To achieve the above objectives, the present invention provides an automated feeding and film-tearing and framing equipment, including a frame; It also includes a feeding unit, a film-tearing unit, a roll-feeding unit, and a frame-loading unit, which are set inside the frame and connected in sequence; The feeding unit is located in the upper left part of the frame and includes an adjustable-size hopper and a vacuum suction cup rotating module. The vacuum suction cup rotating module is located on the right crossbeam of the adjustable-size hopper. The film-tearing unit is located in the middle of the frame and includes a transversely running film-tearing conveyor line, film-tearing roller groups arranged symmetrically on the upper and lower sides of the film-tearing conveyor line, a waste film recycling roll on the upper part of the frame corresponding to the roller group position, and a power traction wheel mechanism and a film-tearing result detection mechanism located above the film-tearing roller group. The surface of the film-tearing roller group is wrapped with adhesive film-tearing tape and equipped with an adjustable pressure drive structure for double-sided synchronous film tearing. The power traction wheel mechanism is used to actively pull the tape to the film-tearing roller group for directional, fixed-length, and fixed-speed transmission to the waste film recycling roll for winding up the peeled waste film and tape. The film-tearing result detection mechanism is located between the film-tearing roller group and the power traction wheel to detect whether the film tearing is achieved, providing a basis for the subsequent defective product screening. The feeding unit is located on the upper left of the film-tearing roller assembly and is fixedly installed on the upper support of the corresponding film-tearing unit on the frame. It includes a feeding mounting frame, a tensioning feeding shaft, and a tape guide wheel. The feeding mounting frame is used to support the components of the feeding unit. The tensioning feeding shaft is horizontally mounted on the feeding mounting frame and is used to sleeve and fix the adhesive feeding roll. The tape guide wheel is located on the side of the feeding mounting frame near the power traction wheel mechanism and is used to guide the tape released from the adhesive feeding roll to the power traction wheel mechanism. The framing unit is located on the far right of the frame and includes a horizontally extending conveyor belt, a black frame positioning mechanism on the side of the end of the conveyor belt, and a discharge suction cup module on the crossbeam between the feeding unit and the framing unit. The black frame positioning mechanism includes a sensor and a positioning block. After the sensor detects that the black frame is in place, it triggers the conveyor belt to stop and locks the black frame. The discharge suction cup module is used to pick up qualified products and accurately place them in the black frame to complete the framing.

[0006] Furthermore, the adjustable-size hopper has a double-row symmetrical vertical frame structure, which is vertically installed on the upper left of the equipment frame. The bottom connects to the horizontal conveyor line, and two independent rectangular product stacking channels are set in parallel on the left and right. Each stacking channel has a horizontally movable clamping plate in the vertical guide groove on the left and right inner sides. The clamping plates are driven by the screw module on the top outer side and slide left and right along the guide groove. The distance between the two clamping plates can be adjusted to accommodate products of different widths. A vertical gate is set directly above the bottom outlet of each stacking channel. The gate moves up and down along the vertical guide rail. The height of the gate matches the thickness of a single product and is used to control the release of single materials one by one. Furthermore, the vacuum chuck rotary module includes an X / Y axis linear slide, a rotary drive mechanism, and a vacuum chuck assembly. The X / Y axis linear slide extends horizontally and vertically, and the cylinder drives the vacuum suction cup assembly to reciprocate between the adjustable-size hopper and the film-tearing conveyor line. The rotary drive mechanism is a servo motor driven motor, which is set at the moving end of the X / Y axis linear slide and is used to drive the vacuum suction cup assembly to rotate 10°-30° around the vertical axis. The vacuum suction cup assembly includes a mounting base and at least two symmetrically distributed silicone vacuum suction cups. The suction cups are connected to an air source via a vacuum generator. Their adsorption surface is parallel to the product stacking surface of the adjustable-size hopper. After rotation, they form an angle of 10°-30° with the conveying direction of the film-tearing conveyor line. The material is precisely picked up and placed by adjusting the angle of the translation and rotation drive mechanism of the X / Y axis linear slide.

[0007] Furthermore, the winding unit includes a winding mounting frame, a tensioning feeding shaft, an axial limiting assembly, and an adjustable damping mechanism; The roll feeding mounting frame is an L-shaped integrated welded bracket. Its vertical end is fixed to the upper bracket in the middle of the corresponding film-tearing unit of the frame by bolts, and its horizontal end extends towards the film-tearing roller group to support all components of the roll feeding unit. The expansion-type feeding shaft is horizontally mounted at the end of the horizontal end of the feeding roll mounting frame. An air-bag type expansion sleeve is fitted on its shaft body. By inflating and expanding, it achieves coaxial fixation with the viscous feeding roll and prevents the tape roll from slipping relative to the shaft body during the feeding process. The axial limiting assembly includes two slidably adjustable limiting discs, which are respectively sleeved on both ends of the expansion feeding shaft. The inner side of the limiting disc is embedded with a rubber buffer pad and is fixed to the expansion feeding shaft by locking bolts. The distance between the two limiting discs can be adjusted according to the different widths of the viscous feeding roll to prevent the tape roll from moving axially. The adjustable damping mechanism is installed at the end of the tensioning feed shaft away from the film-tearing roller assembly and is fixedly connected to the feed roll mounting frame. It includes a damper body and an adjustment knob. By rotating the adjustment knob, the resistance torque of the damper body can be changed, thereby adjusting the release speed of the viscous feed roll and preventing the tape from becoming loose due to rapid release caused by inertia. Furthermore, the film-tearing roller assembly has a mirror-symmetrical structure, and is respectively set above and below the film-tearing conveyor line. Each roller assembly includes a pressing roller assembly and a peeling traction roller. The pressing roller assembly is located between the feeding unit and the power traction wheel, and includes a floating pressing roller and a drive cylinder. The surface of the floating pressing roller is covered with an elastic adhesive layer, and the drive cylinder is used to apply an adjustable pressing force so that the tape is tightly bonded to the protective film on the surface of the product. The peeling traction roller is located on the lower inner side of each roller group and is arranged parallel to the conveying direction of the film peeling conveyor line. It is driven to rotate by a servo motor, and the traction belt moves synchronously with the peeled protective film. The pressing roller assembly and peeling traction roller of the upper and lower sets of film-peeling rollers are coaxially aligned in the vertical direction, so that the upper and lower surfaces are subjected to force at the same time when the product passes through, and the double-sided protective film is peeled off synchronously. The peeled waste film is conveyed together with the tape to the waste film recycling roll at the top of the frame for winding.

[0008] Furthermore, the black frame positioning mechanism includes a photoelectric detection sensor and a pneumatic positioning block assembly. The black frame positioning mechanism is installed on a bracket on the side of the end section of the conveyor belt of the framing unit. The detection end of the photoelectric detection sensor faces the conveyor belt's transport path and is used to detect the arrival status of the black frame. The pneumatic positioning block assembly includes two symmetrically arranged positioning blocks and a drive cylinder, which are fixed on the supports on both sides of the conveyor belt and electrically connected to the photoelectric detection sensor. When the photoelectric detection sensor detects that the black frame has reached the preset position, it triggers the drive cylinder to push the positioning block to move towards the center of the conveyor belt, clamping and positioning the black frame in both directions. At the same time, it triggers the conveyor belt to stop. After the frame is installed, the conveyor belt restarts to transport the frame to the next installation step.

[0009] Furthermore, the waste film recycling roll includes a recycling mounting frame, a servo drive motor, a reduction transmission mechanism, a tensioning recycling shaft, and a waste film guide roller assembly; The recycling mounting frame is a symmetrical frame structure, which is fixed to the frame by bolts and is located on the upper right side of the film tearing roller assembly. It is used to support all the components of the waste film recycling roll. The servo drive motor is fixed to the outer end of the recycling mounting frame, and its output shaft is connected to the input end of the reduction transmission mechanism. The output end of the reduction transmission mechanism is connected to the expansion type recycling shaft through a coupling. The expansion-type recycling shaft is horizontally mounted between two columns of the recycling installation frame. An inflatable rubber expansion sleeve is fitted on the shaft body to fit and fix the waste film recycling paper core, preventing the paper core from slipping relative to the shaft body during the winding process. The waste film guide roller assembly includes two parallel guide rollers, which are rotatably connected to the side of the recycling mounting frame near the film tearing roller assembly via bearing seats. The axis of the guide rollers is parallel to the expansion recycling shaft. After being peeled off by the film-tearing roller assembly, the waste film and tape are guided by the waste film guide roller assembly and then wound onto the recycling paper core of the tensioning recycling shaft. The rotation speed of the servo drive motor is synchronized with the rotation speed of the power traction wheel mechanism of the film-tearing unit to ensure stable winding tension of the waste film.

[0010] Furthermore, the film tearing result detection mechanism includes photoelectric detection switches arranged symmetrically on the top and bottom to detect and judge the film tearing results on both sides. The torn waste film will stick to the tearing tape. Since the product and the film tearing conveyor line form an angle of 10°-30°, the torn waste film will overlap with the edge of the tearing tape to form a triangular-shaped over-edge portion. The photoelectric detection switch detects the over-edge portion of the waste film. If the over-edge waste film is detected, the vacuum suction cup feeding and rotating module will perform the framing step. If no over-edge portion is detected, it is judged as an NG product and is thrown away by the back-end robot, and does not enter the normal operation process. The present invention also provides an automated feeding, film-tearing, and framing integrated machine, which is applied to the above-mentioned automated feeding and film-tearing and framing core unit. The machine includes an integrated machine body, adjustable height shock-absorbing support feet fixedly installed at the four corners of the bottom of the integrated machine body, a transparent safety door hinged to the front of the integrated machine body, and a touch screen embedded in the top of the integrated machine body. The feeding unit, film-tearing unit, winding unit, and framing unit described above are all integrated into a sealed chamber inside the main body of the integrated machine, and are arranged sequentially from left to right along the length of the main body of the integrated machine to form a continuous processing line of feeding-film-framing.

Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0014] like Figure 1 As shown, an automated feeding, film-tearing, and framing equipment includes a feeding unit 2, a film-tearing unit 3, a roll-feeding unit 4, and a framing unit 5 connected sequentially within a frame 1. The equipment uses the frame 1 as its core load-bearing framework. The frame 1 is made of high-strength carbon steel and is a rectangular frame structure. Adjustable support feet are provided at the four corners of the bottom to ensure stable placement of the equipment. Multiple sets of transverse and longitudinal beams and mounting brackets are welded to the top and middle to provide precise installation references for each functional unit. The internal layout of the frame 1 is planned according to the left-center-right process flow. The units are closely connected and have reasonable maintenance space reserved. The specific distribution is as follows: like Figure 2As shown, the upper left part of the frame 1 is the installation area of ​​the feeding unit 2. The adjustable hopper 21 is vertically fixed on the left vertical support, and its bottom is flush with the input end of the film-tearing conveyor line 31 of the film-tearing unit 3. The fixed vacuum suction cup material-picking rotary module is set on the X / Y axis linear slide 231 opposite the hopper 21. It moves laterally through the X / Y axis linear slide 231. The moving end of the module covers the entire range from the material outlet of the hopper 21 to the initial position of the film-tearing conveyor line 31, ensuring that there are no dead angles in the material picking and unloading stroke.

[0015] like Figure 3 As shown, the adjustable-size hopper 21 is a double-row symmetrical vertical frame structure with an overall vertical double-channel layout. Two independent rectangular channels are set in parallel on the left and right. The inner walls of the channels are lined with wear-resistant PTFE plates to prevent scratches on the surface when products are stacked. Each channel has a horizontally sliding clamp 211 embedded in the vertical guide groove on the left and right sides. The top outer side of the clamp is rigidly connected to the nut seat of the screw module 212. The spacing range can be adjusted by manually sliding the clamp along the guide groove to accommodate products of different widths. A vertical gate 214 with the same thickness as a single product is configured directly above the bottom outlet of each channel. The gate adjusts the thickness of the fed product by moving up and down along the vertical guide rail and only allows the bottom single product to pass through the outlet to avoid multiple products being discharged at the same time. The vacuum suction cup material handling rotary module 22 is an integrated execution component consisting of a slide table, a rotary drive, and a suction cup. It is installed on the X / Y axis linear slide table 231 opposite the material bin 21. The X / Y axis linear slide table 231 is equipped with guide rails, and the drive source is a double piston rod cylinder. The cylinder body is fixed on the frame. The vacuum suction cup realizes the reciprocating movement between the material handling area and the film tearing line station by moving the X / Y axis linear slide table 231. The movement speed is adjustable from 0.5m / s to 1m / s. The rotary drive mechanism 232 is a servo-driven rotary motor. The flange is fixed to the moving end of the Y-axis slide, and the output shaft is vertically downward. It has a built-in angle encoder, which can drive the suction cup assembly to rotate 0°-15° around the vertical axis with a positioning accuracy of ≤0.5°, so that the product is at a preset angle to the conveying direction of the film-tearing conveyor line. The vacuum suction cup assembly 233 includes a square aluminum alloy mounting base, the top of which is connected to the output shaft of the rotary motor, and at least two sets of silicone vacuum suction cups are symmetrically distributed at the bottom. Each set contains two bowl-shaped suction cups. The suction cups are made of highly elastic food-grade silicone material, and the bowl-shaped structure improves the adsorption and sealing performance. Each suction cup is connected to the vacuum generator through an independent PU vacuum tube. A photoelectric sensor is integrated next to the assembly to detect the adsorption status in real time and avoid empty or missed pick-ups.

[0016] like Figure 4As shown, the feeding unit 4 is integrated and installed in the upper support area of ​​the frame 1 corresponding to the film-tearing unit 3. The feeding unit 4 is located on the upper left of the film-tearing roller group 32 and is horizontally aligned with the feed end of the power traction wheel mechanism 34. The tape output path in the feeding unit 4 is precisely connected with the clamping gap of the traction wheel set inside it, forming a stable feeding link of tape roll fixing - tension adjustment - directional guidance. The mounting bracket of the feeding unit 4 is fastened to the transverse beam of the frame 1 by bolts. A 10cm operating space is reserved on the outside of the bracket to facilitate the replacement of tape rolls and adjustment of damping parameters.

[0017] The core components of the feeding unit 4 are the feeding mounting frame 41, the expansion feeding shaft 42, the axial limiting component 43, and the adjustable damping mechanism 44. The feeding mounting frame 41 serves as the supporting foundation for the feeding unit. The vertical section is fixed to the upper support of the frame 1, and the horizontal section extends towards the tearing roller assembly 32. The expansion feeding shaft 42 is horizontally mounted at the end of the horizontal end of the feeding mounting frame 41. The shaft body is made of stainless steel, and its diameter is adapted to the inner core of the tape roll. An air-bag type expansion sleeve 421 is fitted in the middle section of the shaft body. It is inflated and deflated through the quick inflation port at the shaft end to achieve coaxial tension and fixation with the inner core of the tape roll, avoiding slippage between the tape roll and the shaft body during the feeding process. The two ends of the shaft body are connected to the mounting frame through deep groove ball bearings to ensure smooth rotation. Axial limiting components 43 are symmetrically sleeved at both ends of the expansion-type feeding shaft 42, i.e. both sides of the tape roll. They include two slidable circular limiting discs 431. The limiting discs are made of aluminum alloy with a thickness of 10mm. A 5mm thick rubber buffer pad 432 is embedded on the inner side. Each limiting disc is fixed to the feeding shaft by bolts. After loosening the bolts, it can slide along the shaft to adjust the distance between the two limiting discs (suitable for tape rolls with a width of 50mm-150mm) and prevent axial movement of the tape roll during feeding. The adjustable damping mechanism 44 is installed at the end of the tensioning feed shaft 42 away from the film tearing roller assembly 32 and is fixed to the vertical section of the feed roll mounting frame 41. The adjustable damping mechanism 44 consists of a damper body and an adjustment knob. The stator of the damper body is fixed to the mounting frame, and the rotor is rigidly connected to the shaft end of the feed shaft. Rotating the adjustment knob can change the friction plate pressure of the damper, thereby adjusting the resistance torque (adjustment range 0.5N・m-2N・m), controlling the release speed of the tape roll, and avoiding the tape from slack stacking due to rapid release caused by inertia.

[0018] like Figure 5As shown, the film-tearing unit 3 is deployed in the transverse core area of ​​the middle of the frame 1. Its transversely running film-tearing conveyor line 31 is horizontally mounted on the carbon steel crossbeam group in the middle of the frame 1. The left end is precisely connected to the unloading station of the vacuum suction cup material-picking rotary module 22 of the feeding unit 2, and the right end is flush with the input end of the conveyor belt 51 of the framing unit 5. The core components of the film-tearing unit 3 include the film-tearing conveyor line 31, the film-tearing roller group 32, the power traction wheel mechanism 34, the waste film recycling roll 33, and the film-tearing result detection mechanism 35. The film-tearing conveyor line 31 runs horizontally through the middle of the frame 1, covering the intermediate path from the feeding unit 2 to the framing unit 5. It adopts a belt-type precision conveyor line. The conveyor belt is made of anti-static PU material (2mm thick) with wear-resistant patterns on the surface to increase product friction. The conveyor line is driven by a servo motor through a synchronous belt, and the speed is adjustable from 0.3m / s to 0.8m / s. Stainless steel limit strips are set on both sides of the conveyor belt, and the width is adapted to the width of the product to prevent the product from running off-center during conveying. Tension adjustment rollers are installed at the bottom of the conveyor line to adjust the tension of the conveyor belt in real time. The film-peeling roller assembly 32 is arranged symmetrically on the upper and lower sides of the film-peeling conveyor line 31. The axis of each roller assembly is perpendicular to the conveying surface of the conveyor line, and the axes of the upper and lower sets are coaxially aligned in the vertical direction. Each roller assembly includes a pressing roller assembly 322 and a peeling traction roller 323. The pressing roller assembly 322 is located below the tape output end of the power traction wheel mechanism 34 and consists of a floating pressure roller and a drive cylinder. The surface of the floating pressure roller is covered with a 3mm thick elastic rubber layer. The drive cylinder is fixed on the vertical adjustment bracket and can apply an adjustable pressure of 5N-20N to make the tape and the protective film on the product surface adhere tightly. The peeling traction roller 323 is located on the lower inner side of each roller assembly. The groove width is the same as the tape width. It is driven to rotate independently by a servo motor. The rotation speed is synchronized with the film-peeling conveyor line 31. The traction tape and the peeled protective film move synchronously to achieve double-sided synchronous film peeling. The power traction wheel mechanism 34 is installed directly above the film-tearing roller assembly 32, located between the pressing roller assembly 322 of the feeding unit 4 and the waste film recycling roll 33. The power traction wheel mechanism 34 includes a servo drive motor, a synchronous belt transmission assembly, a main traction wheel and a floating pressure wheel. The surface of the main traction wheel is provided with anti-slip texture. The floating pressure wheel applies constant pressure through a compression spring. The clamping gap formed by the two is adapted to the thickness of the tape. The speed of the servo motor is synchronized with the adjustable damping mechanism 44 of the feeding unit 4 and the peeling traction roller 323 to ensure that the tape conveying tension is uniform and without slack.The film tearing result detection mechanism 35 is equipped with photoelectric detection switches arranged symmetrically at the top and bottom to detect and judge the film tearing results on both sides. The torn waste film will stick to the tearing waste tape. Since the product and the film tearing conveyor line form an angle of 10°-30°, the torn waste film 37 will overlap with the edge of the tearing waste tape 38 to form a triangular-shaped extra edge. The photoelectric detection switch detects the extra edge waste film. If the extra edge waste film 39 is detected, it will be framed by the vacuum suction cup feeding and rotating module 523. If no extra edge is detected, it is judged as NG product and is thrown out by the vacuum suction cup feeding and rotating module 523, and does not enter the normal operation process.

[0019] The waste film recycling roll 33 is fixed at the end of the frame and is symmetrically distributed on both sides of the film tearing unit 3 with the feeding unit 4. It consists of a recycling mounting frame 331, a servo drive motor 332, a reduction transmission mechanism 333, an expansion-type recycling shaft 334, and a waste film guide roller group 335. The recycling mounting frame 331 is a symmetrical carbon steel frame. The expansion-type recycling shaft 334 is horizontally mounted between the mounting frame columns. The shaft body is fitted with an inflatable rubber expansion sleeve to fix the waste film recycling core and prevent slippage during winding. The waste film guide roller group 335 consists of two parallel guide rollers located between the recycling shaft and the film tearing roller group 32. The roller surface is provided with an annular limiting groove to guide and organize the waste film. The servo drive motor 332 drives the recycling shaft to rotate through the reduction transmission mechanism 333. The rotation speed is synchronized with the power traction wheel mechanism 34 to ensure stable waste film winding tension and avoid wrinkles or breakage of the waste film.

[0020] like Figure 6As shown, the framing unit 5 is deployed in the rightmost area of ​​the frame 1. Its horizontally extending conveyor belt 51 is set parallel to the film-tearing conveyor line 31 of the film-tearing unit 3, ensuring that the product after film tearing can enter the framing station without drop. The main body of the unit is fixed on the carbon steel crossbeam group on the right side of the frame. The core components of the framing unit 5 include the conveyor belt 51, the black frame positioning mechanism 52, and the discharge suction cup module 53. The black frame positioning mechanism 52 is installed on the two side supports at the end of the conveyor belt 51, corresponding to the preset stop position of the black frame. It consists of a photoelectric detection sensor and a pneumatic positioning block assembly 522. The photoelectric detection sensor uses a diffuse reflection photoelectric switch, with the detection end facing the conveyor belt path. The detection distance is adjustable from 0-50mm and is used to identify in real time whether the black frame has reached the positioning position. The pneumatic positioning block assembly 522 includes two symmetrically arranged L-shaped positioning blocks. Each block is rigidly connected to the piston rod of a small double-acting cylinder. The cylinder is fixed on the adjustable supports on both sides of the conveyor belt. Loosening the support bolts can adjust the block spacing (suitable for black frames with a width of 50mm-180mm). When the photoelectric detection sensor detects that the black frame has reached the position, it triggers the cylinder to push the block towards the center of the conveyor belt, clamping and positioning the black frame in both directions. At the same time, it sends a signal to the PLC to stop the conveyor belt 51. After the frame is loaded, the cylinder is depressurized and reset, and the conveyor belt restarts to transport the black frame to the next working step. The discharge suction cup module 53 is installed on the X / Y axis linear slide 231 at the lower right of the waste film recycling roll 33 via the slider guide rail assembly. Its movement range covers the output end of the film tearing conveyor line 31 to the black frame positioning station. The structure is an integrated structure of the X / Y axis linear slide and the vacuum suction cup assembly.

[0021] In the specific implementation process, after the equipment is started, the preset product model can be called through the touch screen. The PLC controller automatically sends the corresponding parameters to each functional unit. There is no need for manual debugging. Only minor adjustments are needed according to the actual production scenario to achieve rapid model changeover. The tensioning feed shaft 42 of the feeding unit 4 fixes the adhesive feed roll through the airbag tensioning sleeve 421. The limiting plate 431 of the axial limiting component 43 limits the axial position of the roll to prevent movement. The adjustable damping mechanism 44 adjusts the resistance torque through the adjusting knob 442 to control the release speed of the tape. The main traction wheel of the power traction wheel mechanism 34 and the floating pressure wheel work together to clamp the tape and transmit it to the tearing roller group 32 at a preset speed. The adjustable-size hopper 21 of the feeding unit 2 drives the clamping plate 211 to slide along the guide groove to adapt to the product width through the screw module 212. The vertical gate 214 moves up and down along the vertical guide rail to control the release of individual materials one by one. The X / Y axis linear slide 231 of the vacuum suction cup picking rotation module 22 drives the vacuum suction cup assembly 233 to move to the discharge port of the hopper 21. The vacuum generator is started to make the silicone suction cup adsorb the product. The rotation drive mechanism 232 drives the suction cup assembly to adjust the angle around the vertical axis and then accurately places the product on the film-tearing conveyor line 31. The film-tearing conveyor 31 moves the product towards the central workstation. After reaching the area of ​​the film-tearing roller assembly 32, the upper and lower symmetrical pressing roller assembly 322 applies a preset pressure under the action of the drive cylinder, so that the tape and the protective film on the upper and lower surfaces of the product are tightly adhered. The peeling traction roller 323 operates synchronously with the film-tearing conveyor 31, pulling the tape and separating it from the peeled protective film, realizing double-sided synchronous film peeling. The peeled waste film is transported to the waste film recycling roll 33 along with the tape. After being sorted and guided by the waste film guide roller assembly 335, it is wound on the recycling paper core of the expansion type recycling shaft 334. The servo drive motor 332 and the power traction wheel mechanism 34 keep their speed synchronized to ensure stable winding tension.The film-tearing result detection mechanism 35 is equipped with photoelectric detection switches arranged symmetrically at the top and bottom to detect and judge the film-tearing results on both sides. The torn waste film will adhere to the tearing tape. Since the product forms an angle of 10°-30° with the film-tearing conveyor line, the torn waste film will overlap with the edge of the tearing tape to form a triangular-shaped excess edge. The photoelectric detection switches detect the excess edge waste film. If excess edge waste film is detected, it will be framed by the vacuum suction cup unloading rotation module 523. If no excess edge is detected, it is judged as NG product and is thrown out by the vacuum suction cup unloading rotation module 523, not entering the normal operation process. The qualified products after film tearing are connected to the conveyor belt 51 of the framing unit 5 via the output end of the film-tearing conveyor line 31. 51 drives the product to the final station. When the black frame is conveyed to the positioning area by the conveyor belt 51, the photoelectric detection sensor detects that the black frame has reached the preset position, triggering the drive cylinder of the pneumatic positioning block assembly 522 to push the positioning block to clamp the black frame in both directions. At the same time, the conveyor belt 51 stops running, and the discharge suction cup module 53 moves along the guide rail of the upper crossbeam to the top of the product. After the vacuum suction cup adsorbs the product, it moves precisely to the top of the black frame. After adjusting the posture, the product is placed stably in the black frame. After the framing is completed, the pneumatic positioning block assembly 522 resets, and the conveyor belt 51 restarts to transport the black frame containing the product to the subsequent storage stage. The entire process is linked with the drive motors and sensors of each unit through the PLC controller to realize the fully automated and coordinated operation of the feeding, film tearing, roll feeding and framing processes.

[0022] The intelligent adjustment function of this equipment is based on the modular process parameter database built into the PLC controller. The database pre-stores the full process parameters corresponding to different product specifications, covering the core operating parameters of each unit such as feeding, winding, film tearing, and framing, including key values ​​such as hopper adaptation width, tape conveying speed, pressing roller pressure, black frame positioning spacing, and vacuum adsorption force. When switching product models is required, the operator selects the target product model through the touch screen on the top of the equipment. The PLC controller immediately triggers a parameter call command, automatically sending the complete set of process parameters corresponding to that model to the actuators and sensors of each functional unit: For the feeding unit, the program drives the screw module to move the clamping plate along the guide groove, automatically adjusting the width of the product stacking channel in the hopper, and simultaneously setting the release height of the vertical gate; For the winding unit, the program adjusts the resistance torque parameter of the adjustable damping mechanism to match the tape release speed of the corresponding product model, and simultaneously adjusts the spacing of the limit plates of the axial limit component to adapt to the tape roll width; For the film tearing unit, the program presets the cylinder output pressure of the pressing roller assembly, the synchronous speed of the peeling traction roller and the film tearing conveyor line, and the tape conveying speed of the power traction wheel mechanism; For the framing unit, the program sets the clamping spacing and clamping force of the pneumatic positioning block assembly, and simultaneously plans the moving path and suction force parameters of the discharge suction cup module. After receiving parameters, the actuators of each unit automatically adjust the mechanical structure parameters through drive components such as servo motors, cylinders, and dampers. During the process, position sensors and tension sensors feed back the adjustment status to the PLC controller in real time, forming a closed-loop control to ensure accurate parameter adjustments. The entire parameter distribution and mechanism adjustment process does not require manual debugging. After the automated adjustment is completed, operators only need to make minor adjustments to individual parameters according to the actual production conditions on site to complete product changeover, significantly reducing changeover time and enabling rapid switching between production of multiple specifications.
