Description

Technical Field

[0001] This invention belongs to the field of automated packaging technology, specifically relating to an OCA automatic counting packaging system and technical method. Background Technology

[0002] Optically Clear Adhesive (OCA) is a key material for lamination bonding of touch display modules, widely used in the manufacturing of screens for electronic devices such as smartphones, tablets, and automotive displays. As consumer electronics products increasingly demand higher bonding precision and cleanliness, OCA finished products, after passing inspection, require efficient and clean automated packaging to ensure accurate product quantity and facilitate warehousing and subsequent logistics management.

[0003] In existing OCA packaging operations, finished OCA products are typically inspected manually or by machine. Subsequent processes such as boxing, bagging, and counting rely heavily on manual labor or semi-automatic equipment, resulting in low overall efficiency and a high risk of contamination. Furthermore, due to the transparent and flexible nature of OCA products, traditional counting methods are insufficiently accurate, leading to missed detections or misjudgments. This results in discrepancies between the actual number of boxes packaged and the statistical figures, often requiring manual verification and significantly impacting the reliability and capacity of the packaging line.

[0013] A second aspect of the present invention provides an automatic OCA counting method, based on the automatic OCA counting packaging system described above, the method comprising: Acquire the counting signal and then monitor the grasping signal; If a capture signal is obtained within a set time after the counting signal is acquired, the number of OCAs is incremented by one.

[0014] Compared with existing technologies, the advantages of this invention are as follows: By setting up a primary conveyor belt, a cartoning mechanism, a secondary conveyor belt, a bagging mechanism, a tertiary conveyor belt, and a control module, this invention achieves full automation of the entire process of OCA finished products from passing inspection to being cartoned, bagged, and transported to a vacuum packaging machine. This effectively avoids the inefficiencies and contamination problems caused by manual or semi-automatic operations. In the cartoning mechanism, the counting unit on the temporary storage component detects the arrival of the OCA finished product and generates a counting signal. The gripping component generates a gripping signal when it successfully grips the product. The control module combines the counting signal and the gripping signal for dual verification counting, significantly compensating for the defects of missed detection and misjudgment caused by the transparent and soft characteristics of OCA in traditional single detection methods, and greatly improving the counting accuracy. At the same time, the control module controls the primary conveyor belt to pause according to the counting signal to prevent excessive accumulation of material on the temporary storage component, ensuring stable gripping by the gripping component and avoiding further expansion of counting deviation caused by accumulation. Through the above improvements, manual opening and verification are eliminated, improving the reliability and capacity of the packaging line. Attached Figure Description

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example 1 As mentioned in the background section, please refer to the relevant technical issues. Figures 1-9This embodiment proposes an automatic counting and packaging system for OCA (Optical Caution Capacity), including a primary conveyor belt 100, a boxing mechanism 200, a secondary conveyor belt 300, a bagging mechanism 400, a tertiary conveyor belt 500, and a control module. The primary conveyor belt 100 is used to transport qualified OCA finished products to the boxing mechanism 200 for packaging. The secondary conveyor belt 300 is used to transport full boxes of OCA finished products to the bagging mechanism 400. The bagging mechanism 400 is used to pack the packaging boxes into packaging bags. The tertiary conveyor belt 500 is used to transport the packaging boxes with packaging bags to a vacuum packaging machine. The boxing mechanism 200 includes: A temporary storage component 210 is connected to the end of the primary conveyor belt 100. A counting unit is provided on the temporary storage component 210. The counting unit is used to generate a counting signal when the OCA finished product arrives at the temporary storage component 210. The gripping component 220 includes at least one adsorption unit; the gripping component 220 is used to grip the OCA finished product temporarily stored on the temporary storage component 210 through the adsorption unit and place it in the packaging box at the beginning of the secondary conveyor belt 300, and generate a gripping signal each time a gripping is successful. The control module is electrically connected to the counting unit and the adsorption unit, and is used to control the primary conveyor belt 100 to pause according to the technical signal, and to count the OCA finished products according to the counting signal and the gripping signal.

[0020] Specifically, such as Figure 1 As shown, this embodiment provides an automatic counting and packaging system for OCA (Optical Cautionless Acid), including a primary conveyor belt 100, a cartoning mechanism 200, a secondary conveyor belt 300, a bagging mechanism 400, a tertiary conveyor belt 500, and a control module. The primary conveyor belt 100 transports qualified OCA products to the cartoning mechanism 200 for packaging; the secondary conveyor belt 300 transports full cartons of OCA products to the bagging mechanism 400; the bagging mechanism 400 places the packaging boxes into packaging bags; and the tertiary conveyor belt 500 transports the packaging boxes, now in bags, to a vacuum packaging machine. This achieves full automation of the OCA product process from cartoning and bagging to vacuum packaging, effectively avoiding the inefficiencies and contamination problems associated with manual or semi-automatic operations.

[0021] The cartoning mechanism 200 includes a temporary storage component 210 and a gripping component 220. The temporary storage component 210 is connected to the end of the primary conveyor belt 100, and a counting unit is provided above it. When the OCA finished product is conveyed from the primary conveyor belt 100 to the temporary storage component 210, the counting unit detects the arrival of the OCA finished product and generates a counting signal. The control module is electrically connected to the counting unit. After receiving the counting signal, it controls the primary conveyor belt 100 to pause, preventing excessive accumulation of material on the temporary storage component 210 due to continuous conveying of subsequent OCA finished products, thereby ensuring that the gripping component 220 can grip stably.

[0022] The gripping component 220 includes at least one adsorption unit for gripping the OCA finished product temporarily stored on the temporary storage component 210 and placing it into a packaging box at the beginning of the secondary conveyor belt 300. Each successful grip generates a gripping signal. The control module is also electrically connected to the adsorption unit, capable of receiving the gripping signal and performing dual verification counting of the OCA finished product based on both the counting signal and the gripping signal: the OCA quantity is incremented only if the corresponding gripping signal is successfully received within a set time after the counting signal. This mechanism overcomes the shortcomings of traditional single-detection methods, such as missed detections and misjudgments due to the transparent and flexible nature of OCA, significantly improving counting accuracy, avoiding counting deviations caused by gripping failures, eliminating the need for manual box opening for verification, and enhancing the reliability and capacity of the packaging line.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, this embodiment further describes the counting unit and the temporary storage component 210. The counting unit includes a ranging sensor 211, and the temporary storage component 210 includes a base 212. Multiple sets of guide units are arranged on the base 212 along a first direction (i.e., a horizontal direction perpendicular to the conveying direction of the primary conveyor belt 100). Each set of guide units includes multiple guide rollers 213 arranged along a second direction (i.e., parallel to the conveying direction of the primary conveyor belt 100). The guide rollers 213 are embedded within the base 212, their rotation axes extend along the first direction, and the upper edge of the guide rollers 213 protrudes from the top surface of the base 212. The protrusion height is precisely designed so that the guide roller 213 is only slightly higher than the top surface of the base 212 (e.g., 1-2 mm). This ensures that the OCA finished product rolls in contact with the guide roller 213 during transport, achieving a smooth guiding effect and reducing friction and static electricity accumulation. It also prevents the OCA finished product (especially thinner and softer specifications) from bending excessively or developing local indentations on the roller surface due to excessive protrusion height, thereby protecting the flatness and optical performance of the product.

[0024] A groove 214 is provided at the end of the base 212 away from the primary conveyor belt 100, and a distance sensor 211 is embedded in the groove 214. As a feasible and preferred embodiment, the distance sensor 211 can be an ultrasonic sensor, with its emission port vertically upward installed in the groove 214. When the OCA product has not reached the end of the base 212, the distance detected by the ultrasonic sensor is a larger value from the sensor to the unobstructed space above; when the OCA product is conveyed by the guide roller 213 to the end of the base 212 and just covers the groove 214, the bottom surface of the OCA product reflects ultrasonic waves, and the distance detected by the sensor suddenly decreases to a smaller value (i.e., the distance from the sensor to the bottom surface of the OCA product). When this detected distance is less than a preset set distance threshold, the distance sensor 211 determines that the OCA product has stably reached the gripping station of the temporary storage component 210 and generates a counting signal. This non-contact detection method avoids touching the surface of the OCA finished product, preventing scratches or contamination. Furthermore, the ultrasonic sensor is insensitive to transparent materials, reliably identifying the presence of the OCA finished product and overcoming the shortcomings of traditional photoelectric sensors that are prone to missed detection due to the transparency of OCA. By embedding the ranging sensor 211 within the groove 214, with its top surface lower than the highest contour of the guide roller 213, it is ensured that the OCA finished product will not directly rub against the sensor surface during transport, protecting the sensor and guaranteeing long-term operational stability. This precise arrival detection provides a reliable trigger point for the control module to promptly pause the primary conveyor belt 100, prevent material accumulation, and facilitate subsequent dual-verification counting.

[0025] Furthermore, Figures 2 to 4 This embodiment further describes the gripping and positioning area 215 and the adsorption unit. At least two gripping and positioning areas 215 are formed on the top surface of the base 212, each located between two adjacent sets of guide units. Guide rollers 213 are embedded in the base 212 and partially protrude, with an arc-shaped surface, and gaps exist between adjacent guide rollers 213. If the suction nozzle 224 directly adsorbs the OCA finished product area above the guide rollers 213, due to the softness of the OCA finished product and the discontinuous roller surface support below, the adsorption area will experience localized suspension or deformation due to unevenness, resulting in a poor seal between the suction nozzle 224 and the OCA finished product, insufficient vacuum, and a significant decrease in adsorption force, easily leading to gripping failure or dropping. To solve this problem, this application provides a flat gripping and positioning area 215 between two adjacent sets of guide units. Below this area is the solid plane of the base 212, providing a flat and continuous rigid support for the OCA finished product. When the OCA finished product is conveyed to the end of the base 212, the part that is to be gripped is located exactly above these gripping positioning areas 215, thereby ensuring that the suction nozzle 224 can perform adsorption on a flat surface when it descends. This effectively avoids the problem of uneven adsorption and air leakage caused by the gap of the lower guide roller 213, and significantly improves the reliability and stability of adsorption.

[0026] The adsorption unit includes a telescopic device 221, a mounting frame 222, and a suction device. The telescopic device 221 is equipped with a telescopic rod 223 that can extend and retract along a third direction (vertical direction). The mounting frame 222 is fixedly installed on the free end of the telescopic rod 223 and moves up and down with the telescopic rod 223. The mounting frame 222 is equipped with at least two sets of suction nozzles 224, each set of suction nozzles 224 corresponding to a gripping positioning area 215, and multiple suction nozzles 224 are arranged at intervals in each set. In this way, each set of suction nozzles 224 faces the gripping positioning area 215 below when it descends, and multiple suction nozzles 224 jointly adsorb the same OCA product, resulting in a uniform distribution of adsorption force, which can avoid insufficient local adsorption force caused by the large area and soft and easily deformable nature of the OCA product.

[0027] The suction device is connected to each nozzle 224 via tubing and is electrically connected to the control module. When the telescopic device 221 drives the nozzle 224 to descend to the surface of the OCA product closely attached to the gripping positioning area 215 and initiates suction, a negative pressure is formed inside the nozzle 224. The suction device monitors the vacuum level of each nozzle 224 in real time. If the nozzle 224 successfully adsorbs the OCA product, the vacuum level will drop to a lower value (i.e., less than the set vacuum level) due to the good seal between the OCA product and the nozzle 224. At this time, the suction device generates a gripping signal, indicating that the gripping was successful. Conversely, if the nozzle 224 fails to fit well (e.g., due to air leakage caused by uneven support underneath), the vacuum level cannot reach the set threshold, and no gripping signal will be generated. This vacuum detection mechanism can accurately determine whether each gripping action has truly and successfully lifted the OCA product from the temporary storage component 210, thereby providing reliable gripping success feedback to the control module. The control module performs dual verification by combining the counting signal and the grasping signal. Only when the grasping signal arrives within a set time after the counting signal will the OCA count be incremented by one, effectively avoiding false counts caused by adsorption failures and significantly improving counting accuracy.

[0028] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, this embodiment further illustrates the alternating placement of the rotating device 230 and the pads. The temporary storage component 210 and the starting ends of the secondary conveyor belt 300 are distributed on opposite sides of the boxing mechanism 200, that is, the temporary storage component 210 is located on one side of the boxing mechanism 200, and the packaging box at the starting end of the secondary conveyor belt 300 is located on the opposite side of the boxing mechanism 200. The boxing mechanism 200 also includes the rotating device 230 and a placement platform 240 for placing the pads, located on one side of the rotating device 230. The placement platform 240 is located around the rotating device 230. Specifically, the temporary storage component 210, the placement platform 240, the packaging box at the starting end of the secondary conveyor belt 300, and an empty workstation (i.e., the position opposite to the placement platform 240) are arranged sequentially along the rotation direction of the rotating device 230.

[0029] The output shaft of the rotating device 230 extends along a third direction (vertical direction) and is drivenly connected to the rotating frame 231. The rotating device 230 rotates 90° each time, enabling precise intermittent indexing motion. The rotating frame 231 has four cross-shaped support arms around its circumference, each support arm having a suction unit at its free end. The four support arms include two first arms 232 and two second arms 233, which are arranged alternately along the circumference of the rotating device 230. The suction unit located at the free end of the first arm 232 is used to grip the finished OCA product, and the suction unit located at the free end of the second arm 233 is used to grip the pad.

[0030] The rotating device 230 is electrically connected to the control module, which is configured to control the adsorption units at the free ends of the first arm 232 and the second arm 233 to alternately hover above the packaging box, so that the OCA finished product and the gasket are alternately placed inside the packaging box. The specific working process is as follows: Taking a certain initial position as an example, when the adsorption unit on the first arm 232 is above the temporary storage component 210, the adsorption unit descends to grab the OCA finished product (its specific structure and vacuum detection method have been described in detail in the previous embodiments, and will not be repeated here). Meanwhile, since the four arms are arranged in a cross shape and the rotating device 230 rotates 90° each time, the adsorption unit on the second arm 233 of the previous stage is located above the placement platform 240, and the adsorption unit descends to grab a pad; the adsorption unit on the second arm 233 of the next stage (that is, the one located opposite the empty workstation of the temporary storage component 210) does not perform adsorption action; while the adsorption unit on the other first arm 232 located above the packaging box (if it has previously adsorbed OCA finished products) descends to release the OCA finished products into the packaging box, and does not release if the adsorption unit is empty. After completing the above actions, the rotating device 230 rotates 90° clockwise or counterclockwise. The first arm 232, originally located above the temporary storage component 210, carrying the OCA product, moves to the placement table 240. The second arm 233, originally located above the placement table 240, carrying the pad, moves to the packaging box. The first arm 232, originally located above the packaging box, becomes unloaded and moves to an empty workstation. The second arm 233, originally located at an empty workstation, moves to the temporary storage component 210 to prepare to grab the next pad. This cycle repeats, with the first arm 232 and the second arm 233 alternately performing grabbing or placing actions every 90° rotation, achieving a layered packaging method where one layer of OCA product and one layer of pad are sequentially placed into the packaging box. This alternating placement method effectively avoids adhesion or scratches caused by direct contact between OCA products. At the same time, the multi-station parallel operation of the rotating device 230 greatly improves the boxing efficiency, and the control module ensures the continuity and reliability of the adsorption and release actions through precise rotation angle and timing control.

[0031] Furthermore, Figure 1 , Figures 6 to 9 This embodiment further describes the bagging mechanism 400. The bagging mechanism 400 includes a support platform 410 and a bagging assembly 420. The support platform 410 is provided with a bagging assembly 430 and a bag-supporting assembly 440.

[0032] The bag-supporting assembly 440 includes four support rods 441 and has a first state and a second state. In the first state, the four support rods 441 converge to form a smaller assembly, allowing the bag-feeding assembly 420 to easily fit the packaging bag onto the four support rods 441. In the second state, the four support rods 441 expand outward, opening the bag opening to a size that can accommodate the packaging box. This two-stage design of convergence and expansion makes bag fitting simple and quick, while ensuring that the bag opening is evenly opened, providing a neat entrance for subsequent packaging box insertion.

[0033] The bagging assembly 430 is slidably mounted on the support platform 410 and has a first station and a second station. In the first station, the bagging assembly 430 docks with the end of the three-stage conveyor belt 500 to receive the pre-boxed OCA finished product packaging boxes conveyed by the three-stage conveyor belt 500. In the second station, the bagging assembly 430 slides along the support platform 410 to a position close to the bag-expanding assembly 440 and contacts it. This contact triggers the bag-expanding assembly 440 to switch from a first state (converging) to a second state (expanding). After the bag opening is opened, the bagging assembly 430 further operates (e.g., flipping or pushing) to push the packaging box carried on it into the opened packaging bag, completing the automatic bagging. After bagging is completed, the bagging assembly 430 returns to the first station, and the bag-expanding assembly 440 returns to the first state, awaiting the next bagging and bagging cycle.

[0034] With the above configuration, the sliding of the bagging component 430 not only transports the packaging box but also serves as a mechanical signal to trigger the state switching of the bag-opening component 440. No additional sensors or independent drive mechanisms are required, resulting in a compact structure and simple control. The entire bagging process is automated, avoiding the inefficiency and contamination risks of manual bagging and filling, while ensuring the stability and consistency of the bag opening, providing a good sealing foundation for subsequent vacuum packaging.

[0035] Furthermore, Figure 6 and Figure 7 This embodiment further describes the bagging assembly 430. The bagging assembly 430 includes a base 431, a tray 432, and a driving device 433.

[0036] The base 431 is slidably connected to the support platform 410 in the fifth direction (parallel to the top surface of the pallet 432 and perpendicular to the conveying direction of the three-stage conveyor belt 500). A pair of hinge frames 434 are provided at one end of the base 431 near the bag support assembly 440. One end of the pallet 432 is hinged to the hinge frame 434, and the other end freely rests on the upper surface of the base 431. In the initial state, the pallet 432 is horizontal, with its top surface approximately flush with the conveying surface of the three-stage conveyor belt 500, to smoothly receive the packaging boxes conveyed from the end of the three-stage conveyor belt 500. Multiple support rollers 435 are arranged on the top surface of the pallet 432 along the fourth direction (parallel to the conveying direction of the three-stage conveyor belt 500), and the rotation axis of the support rollers 435 extends along the fifth direction. When the packaging box is pushed onto the pallet 432, the support roller 435 can roll to support the bottom of the packaging box, greatly reducing sliding friction and making the packaging box move smoothly during subsequent flipping and pushing, avoiding the packaging box tilting or getting stuck due to excessive resistance.

[0037] The drive unit 433 is mounted on the hinge frame 434 and is connected to the pallet 432 via a transmission connection. It drives the pallet 432 to rotate upwards around the hinge axis, lifting the free end of the pallet 432 towards the bag-supporting assembly 440. Specifically, when the base 431 drives the pallet 432 to slide to the second position (i.e., near the bag-supporting assembly 440), and the bag-supporting assembly 440 has opened the bag opening, the drive unit 433 starts, pushing the pallet 432 upwards. Under the influence of gravity and the rolling action of the support roller 435, the packaging box on the pallet 432 slides along the inclined surface of the pallet 432 towards the bag-supporting assembly 440 until it is completely inserted into the opened packaging bag. After bagging is completed, the drive unit 433 reverses its action, pulling the pallet 432 back to a horizontal position, and the base 431 returns to the first position, awaiting the next packaging box.

[0038] Through the above structure, the bagging assembly 430 achieves smooth receiving of the packaging box, low-friction conveying, and continuous flipping and pushing of the bag. The support roller 435 effectively reduces the friction between the packaging box and the pallet 432, preventing damage or displacement of the packaging box due to pushing resistance. Compared with the linear pushing method, the articulated flipping structure can achieve stable sliding of the packaging box within a shorter stroke, and the pallet 432 naturally forms a slope after flipping, which facilitates the packaging box sliding into the bag with the assistance of gravity, reducing the load on the drive device 433 and improving the reliability and consistency of bagging.

[0039] Furthermore, Figures 6 to 9This embodiment further describes the linkage triggering structure between the bag-supporting assembly 440 and the bag-filling assembly 430. A triggering part 436 is provided at the bottom of the base 431 near the end of the bag-supporting assembly 440. A first wedge-shaped surface 437 is provided on each of the opposite sides of the front end of the triggering part 436. The bag-supporting assembly 440 includes a pair of upright plates 450, a pair of sliding seats 460, and a pair of sliding blocks 470.

[0040] A pair of upright plates 450 are fixedly distributed on both sides of the support platform 410, arranged parallel to each other and vertically. Each upright plate 450 has a protruding guide portion 451 on its inner side (i.e., the side closest to each other), and the guide portion 451 has a second wedge-shaped surface 452. A pair of sliding seats 460 are respectively arranged corresponding to the pair of upright plates 450 and slidably mounted on the support platform 410, with their sliding direction being the fifth direction (i.e., a horizontal direction parallel to the top surface of the pallet 432 and perpendicular to the conveying direction of the three-stage conveyor belt 500). Each sliding seat 460 has a third wedge-shaped surface 461 at the position corresponding to the first wedge-shaped surface 437. When the bagging assembly 430 moves towards the bag-supporting assembly 440 along the fifth direction, the front end of the trigger part 436 is inserted between the two sliding seats 460, and the first wedge-shaped surface 437 contacts and slides relative to the third wedge-shaped surface 461, thereby pushing the sliding seats 460 apart to both sides, causing the two sliding seats 460 to move away from each other along the fifth direction. Each sliding seat 460 has a first guide post 462 on the side near the corresponding upright plate 450. The first guide post 462 passes through the upright plate 450 and can slide relative to the upright plate 450. A first spring reset member 463 is sleeved on the first guide post 462. One end of the first spring reset member 463 is fixed to the sliding seat 460, and the other end is fixed to the upright plate 450. When the trigger part 436 pushes away from the sliding seat 460, the first spring reset member 463 is compressed; when the bagging assembly 430 retracts, the elastic force of the first spring reset member 463 causes the sliding seat 460 to automatically reset.

[0041] Each sliding seat 460 has a fixing block 464 and a mounting plate 465 on its top surface. The mounting plate 465 is located on the side of the fixing block 464 near the bagging assembly 430, and a limiting part 466 is provided on the top of the mounting plate 465. A support rod 441 is installed on the end of the fixing block 464 away from the mounting plate 465. Therefore, the support rods 441 on the two fixing blocks 464 are located on the left and right sides respectively. When the sliding seat 460 moves outward, the two support rods 441 also move horizontally outward, thereby opening the bag opening in the horizontal direction.

[0042] A pair of sliding blocks 470 are slidably mounted on mounting plates 465 of a pair of sliding seats 460, with their sliding direction perpendicular to the top surface of the support platform 410 (i.e., vertical direction). Each sliding block 470 has a support rod 441 mounted at its front end, and a second guide post 471 at its top. The second guide post 471 passes through the limiting part 466 and is slidably relative to the limiting part 466. A second spring return member 472 is sleeved on the second guide post 471, with one end fixedly connected to the sliding block 470 and the other end fixedly connected to the limiting part 466. Each sliding block 470 has a fourth wedge-shaped surface 473 corresponding to the second wedge-shaped surface 452. When the sliding seat 460 is pushed away by the trigger part 436, the sliding block 470 moves horizontally along with the sliding seat 460. At the same time, since the upright plate 450 is fixed, the fourth wedge surface 473 on the sliding block 470 slides relative to the second wedge surface 452 on the upright plate 450, forcing the sliding block 470 to move vertically upward (or downward) along the mounting plate 465, thereby driving the support rod 441 at its front end to move vertically. The support rods 441 on the two sliding blocks 470 can move upward and downward respectively (the specific direction is determined by the inclination direction of the wedge surface), thereby realizing the vertical opening of the bag opening.

[0043] Through the aforementioned linkage mechanism, when the bagging assembly 430 moves to the second station, the trigger 436 sequentially drives the sliding seat 460 to move horizontally outward and the sliding block 470 to move vertically, causing the four support rods 441 to automatically switch from the first converged state to the second expanded state, evenly opening the pre-packaged bag opening. The entire switching process is completed entirely by mechanical contact and wedge surface cooperation, requiring no additional sensors or independent drivers, resulting in a compact structure and reliable response. After bagging is completed, the bagging assembly 430 retracts, the sliding seat 460 resets under the action of the first spring reset member 463, and the sliding block 470 resets under the action of the second spring reset member 472. The four support rods 441 converge again, awaiting the next bagging. At this time, the packaging box of the Taoyou packaging bag falls onto the three-stage conveyor belt 500 and is transported. This purely mechanical linkage reset design reduces the complexity of electrical control and improves the stability of the system.

[0044] Furthermore, such as Figure 10 As shown, this embodiment further describes the bagging assembly 420. The bagging assembly 420 includes a support frame 421 and a pair of electric grippers 422. A swing device 423 is slidably mounted on the support frame 421, and its sliding direction is the fifth direction (i.e., a horizontal direction parallel to the top surface of the pallet 432 and perpendicular to the conveying direction of the three-stage conveyor belt 500). The swing device 423 is provided with a swing arm 424, and a U-shaped bracket 425 is provided at the bottom end of the swing arm 424. Each end of the U-shaped bracket 425 is provided with a mounting plate 426. The pair of electric grippers 422 are slidably mounted on the two mounting plates 426 respectively, and their sliding direction is also the fifth direction.

[0045] During operation, the swing device 423 drives the swing arm 424 to swing around the vertical axis, moving the U-shaped bracket 425 and its pair of electric grippers 422 to the bag-picking or bag-packing station. The electric grippers 422 are used to grip the two edges of the bag opening. When picking up the bag, the pair of electric grippers 422 slide relative to each other along the mounting plate 426, adjusting the spacing to accommodate different sizes of packaging bags. After gripping the bag opening, the swing device 423 swings the packaging bag to the position of the bag-supporting assembly 440. At this time, the four support rods 441 of the bag-supporting assembly 440 are in the first state (converged), and the electric grippers 422 cover the bag opening outside the four support rods 441. Subsequently, the electric grippers 422 release and retract, and the bag-supporting assembly 440 switches to the second state (expanded) to open the bag opening, completing the automatic bag-packing.

[0046] By incorporating a sliding swing device 423 and an adjustable-gap electric gripper 422, the bagging assembly 420 can adapt to packaging bags of different sizes, improving the system's versatility. The electric gripper 422's gripping and releasing actions are precise and controllable. Combined with the swing conveying function of the swing device 423, it enables the automatic transfer of packaging bags from the bag-picking station to the bagging station without manual intervention, effectively avoiding the risk of contamination from human contact, while also improving the speed and consistency of bagging.

[0047] Furthermore, such as Figure 1 As shown in the illustration, this embodiment further describes the primary conveyor belt 100. The primary conveyor belt 100 is made of PU (polyurethane) material, which has a smooth, wear-resistant surface and is not prone to dust generation. This effectively reduces frictional damage and particulate contamination of the OCA finished product during transport, meeting the high cleanliness requirements of OCA optical adhesive products. Simultaneously, static elimination modules (such as ion bars or brush-type static eliminators) are provided on both sides of the primary conveyor belt 100 to neutralize the static electricity generated by friction during the transport of the OCA finished product. Because OCA finished products are transparent, soft, and easily attract dust, static electricity makes their surface more susceptible to adhering to tiny particles from the environment, leading to bubbles or impurities during subsequent bonding. By setting up static elimination modules, static electricity accumulation can be significantly reduced, maintaining the cleanliness of the OCA finished product surface and improving product yield.

[0048] A transparent protective plate 110 is installed above the primary conveyor belt 100, with openings at both the beginning and end of the belt. The transparent protective plate 110 is made of transparent material (such as acrylic or polycarbonate), allowing operators to easily observe the conveying status of the OCA finished products on the conveyor belt from the outside, while effectively isolating dust and foreign objects from the external environment, preventing them from falling onto the surface of the OCA finished products. Simultaneously, the transparent protective plate 110 prevents operators from accidentally touching the conveyor belt and the conveying OCA finished products, improving the safety of equipment operation. The openings at the beginning and end allow qualified OCA finished products to smoothly enter the primary conveyor belt 100 from the previous station and smoothly exit to the temporary storage component 210 at the end of the primary conveyor belt 100, avoiding interference from the protective plate in material conveying. Through this structure, the primary conveyor belt 100 ensures efficient conveying while maximizing the fulfillment of the special requirements of OCA products for anti-static, anti-contamination, and high visibility.

[0049] Example 2 Based on the above embodiment 1, please refer to Figure 10 This embodiment provides an OCA automatic counting method based on the OCA automatic counting packaging system described in Embodiment 1. The method includes the following steps S1-S2: S1: Acquire the counting signal and monitor the grasping signal after acquisition.

[0050] Specifically, in step S1, when the primary conveyor belt 100 transports the qualified OCA finished product to the temporary storage component 210, the ranging sensor 211 embedded at the end of the base 212 detects the arrival of the OCA finished product and generates a counting signal. After obtaining the counting signal, the control module immediately begins monitoring whether the gripping component 220 returns a gripping signal. At the same time, the control module controls the primary conveyor belt 100 to pause according to the counting signal, preventing the continued transport of subsequent OCA finished products from causing material accumulation on the temporary storage component 210, thereby providing a stable gripping station for the gripping component 220.

[0051] S2: If a capture signal is obtained within a set time after the counting signal is acquired, the OCA count is incremented by one.

[0052] Specifically, in step S2, the gripping component 220 grips the OCA finished product on the temporary storage component 210 through the adsorption unit and places it in the packaging box at the beginning of the secondary conveyor belt 300. Each time a gripping is successful, the suction device detects that the vacuum degree of the suction nozzle 224 is less than the set vacuum degree, thus generating a gripping signal. The control module determines whether the corresponding gripping signal is received within a set time period after the acquisition of the counting signal (e.g., 0.5 seconds to 2 seconds, which can be adjusted according to the actual production cycle). If the gripping signal is successfully received within the set time period, it indicates that the OCA finished product has not only reached the temporary storage component 210, but has also been reliably gripped and transferred by the adsorption unit. At this time, the control module increments the OCA count by one. If no gripping signal is received after the set time period (e.g., due to suction failure, OCA finished product slippage, or gripping component failure), the count is not accumulated, and an alarm is issued to prompt the operator to check.

[0053] This method employs a dual signal verification mechanism to sequentially correlate the counting signal and the grasping signal. The quantity is only counted when both conditions for the OCA finished product's "arrival" and "successful grasping" are met. This effectively avoids counting deviations caused by sensor misdetections (such as unreliable identification of transparent OCA) or grasping failures (such as nozzle leaks or insufficient vacuum). Compared to traditional single-sensor counting methods, this method significantly improves counting accuracy, ensuring that the actual number of OCA finished products packaged strictly matches the statistical value. No manual opening and verification is required, enhancing the reliability and automation level of the packaging line. Furthermore, the introduction of a set time interval filters out abnormal delays, preventing false counts caused by material conveying blockages or grasping action timeouts.
