Description

Technical Field

[0001] This invention relates to the field of production and processing technology of pallet boxes, and in particular to a window labeling device for folding pallet boxes. Background Technology

[0002] Collapsible crates are a type of foldable, durable, and space-efficient packaging container. Due to their flexible structure and ease of storage and transportation, they are widely used in the new energy field, especially in the transport of lithium batteries.

[0003] In practical applications, windows are usually required on the enclosure of the pallet box so that operators can observe the status of the lithium batteries inside the box in real time. Velcro is required to be attached to the edges of the windows to ensure reliable opening and closing and to prevent the external environment from adversely affecting the lithium batteries inside the box. At the same time, card pockets are also required to be attached to specific locations on the enclosure to hold information cards and achieve full traceability of the transportation process.

[0004] However, currently, opening windows, attaching Velcro, and attaching card pockets are all done manually, and these operations are scattered across different workstations. Operators need to repeatedly transfer the pallet boxes between multiple workstations, which not only increases the complexity and time cost of the logistics process, but also results in low overall processing efficiency due to the limitations of individual skill levels in manual operation. Furthermore, in the window-opening process, the pallets are usually pre-marked at designated locations before opening the windows, and workers must use a utility knife to cut along these marks. Because the material at the marks is dense and hard, the cutting process easily causes the blade to chip, affecting not only the accuracy and surface quality of the window opening but also posing a high safety risk, such as flying blade fragments or injuring operators, seriously threatening production safety. Summary of the Invention

[0005] This invention provides a window labeling device for a folding collapsible box, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A window-opening labeling device for a folding collapsible box includes: a frame, wherein the frame is provided with a conveying mechanism for conveying the collapsible box, characterized in that the frame is further integrated with a transport positioning component, a pressing and leveling component, a laser window opening component and an attaching component; The transport positioning component includes a blocking mechanism located at the end of the conveying mechanism and a side-positioning mechanism whose pushing direction is perpendicular to the conveying direction of the conveying mechanism. The blocking mechanism and the side-positioning mechanism work together to achieve bidirectional precise positioning of the enclosure box in the horizontal plane. The pressing and leveling assembly includes a suction cup group and a pressing drive component for driving the suction cup group to rise and fall, for adsorbing the window surface of the enclosure box to be opened and keeping it in a horizontal state. The laser window opening assembly includes a gantry moving mechanism and a laser cutting head mounted on the gantry moving mechanism. The gantry moving mechanism is used to drive the laser cutting head to move along a set cutting trajectory in the horizontal plane to perform laser cutting and window opening on the side of the enclosure box to be opened. The attachment assembly includes a robotic arm and two sets of quick-change modules that can be connected to quick-change connectors on the robotic arm. One set of quick-change modules is equipped with a folding clamp for attaching Velcro, and the other set of quick-change modules is equipped with a sponge suction cup for attaching card pockets. The robotic arm switches between different quick-change modules through the quick-change connectors to complete the attachment of Velcro and card pockets.

[0007] Furthermore, the blocking mechanism includes two rows of rollers, a blocking plate, and a linear drive assembly; Two roller rows are spliced ​​at the conveying end of the conveying mechanism, and a baffle plate is disposed between the two roller rows. The linear drive assembly is used to drive the baffle plate to move in the opposite direction along the parallel conveying direction to push the enclosure box to a preset position.

[0008] Furthermore, the edge positioning mechanism includes two pusher plates and a pusher assembly; the pusher assembly is fixed on the frame, and the pusher plates are disposed between adjacent rollers of the conveying mechanism; The upper end of the pusher plate can extend out of the conveying plane of the conveying mechanism; the pusher assembly is used to drive the pusher plate to move perpendicular to the conveying direction so as to push the enclosure box to the fixed grid on the frame.

[0009] Furthermore, the suction cup assembly is provided in two sets, and is respectively located on both sides of the window opening position of the enclosure box; The downward driving component drives the two sets of suction cups to move down synchronously to press and adsorb the window surface to be opened, and then moves up to lift it so that the window surface to be opened is kept in a horizontal tension state.

[0010] Furthermore, the laser window opening assembly also includes a lifting drive assembly, a laser displacement sensor, and a visual positioning unit; The lifting drive assembly is used to drive the laser cutting head to move vertically to a set cutting height. The laser displacement sensor is used to detect the vertical distance between the laser cutting head and the surface to be cut. The vision positioning unit is used to collect point information of the area to be cut in order to adjust the cutting trajectory and position.

[0011] Furthermore, omnidirectional balls are symmetrically arranged on both sides of the laser cutting head, and the bottom contact surfaces of the two omnidirectional balls are lower than the laser emitting end of the laser cutting head; The laser cutting head is vertically mounted on the actuator of the lifting drive assembly.

[0012] Furthermore, the attachment assembly also includes a card pocket peeling mechanism and a Velcro peeling mechanism; The card bag peeling mechanism is located at the card bag feeding station and includes a peeling knife, a clamping arm and a paper peeling drive, used to peel the release paper off the card bag; The hook and loop fastener peeling mechanism is located at the hook and loop fastener feeding station and includes an unwinding shaft, a peeling platform, and a rewinding shaft, used to peel off the release paper of the hook and loop fastener.

[0013] Furthermore, the folding chuck includes a mounting base, two needle-punching clamps, and a gripper drive assembly; The two needle-punching clamps are symmetrically hinged to the mounting base. The gripper drive assembly is used to drive the two needle-punching clamps to rotate synchronously, so that the material-picking surfaces of the two needle-punching clamps change from a coplanar material-picking state to a relatively parallel folded attachment state.

[0014] Furthermore, it also includes isolation panels; The robotic arm grabs the isolation plate through the quick-connect joint and inserts the isolation plate below the surface of the enclosure box to be cut to isolate the non-processed surface of the enclosure box.

[0015] Furthermore, it also includes a fume hood and a fan. The fume hood is installed on the push plate of the edge positioning mechanism, and the fan is connected to the fume hood to draw out the smoke generated during the laser cutting process.

[0016] The technical solution of this invention can achieve the following technical effects: This invention integrates three key processes—window opening, Velcro application, and card bag application—into a single frame by combining a transport positioning component, a pressing and leveling component, a laser window opening component, and an attachment component. This achieves fully automated and continuous production, changing the inefficient traditional manual operation model that involves scattered operations at different workstations and multiple transfers of pallet boxes. It effectively solves the technical problems of low processing efficiency, poor product consistency, and safety risks associated with manual operation, significantly improving production efficiency, product quality, and operational safety.

Detailed Implementation

[0019] 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.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1-12As shown, this application provides a window-opening labeling device for a folding collapsible box, including a frame 1, a conveying mechanism 2 for conveying the collapsible box on the frame 1, and a transport positioning component 3, a pressing and leveling component 4, a laser window opening component 5 and an attaching component 6 integrated on the frame 1. The transport positioning component 3 includes a blocking mechanism 31 located at the end of the conveying mechanism 2, and a side positioning mechanism 32 whose pushing direction is perpendicular to the conveying direction of the conveying mechanism 2. The blocking mechanism 31 and the side positioning mechanism 32 work together to achieve bidirectional precise positioning of the enclosure box in the horizontal plane. The pressing and leveling assembly 4 includes a suction cup assembly 41 and a pressing drive 42 for driving the suction cup assembly 41 to rise and fall, for adsorbing the window surface of the enclosure box to be opened and keeping it in a horizontal state. The laser window opening assembly 5 includes a gantry moving mechanism 51 and a laser cutting head 52 mounted on the gantry moving mechanism 51. The gantry moving mechanism 51 is used to drive the laser cutting head 52 to move along a set cutting trajectory in the horizontal plane to perform laser cutting and window opening on the window surface to be opened of the enclosure box. The attachment assembly 6 includes a robotic arm 61 and two quick-change modules 62 that can be connected to quick-change connectors on the robotic arm 61. One quick-change module 62 is equipped with a folding clamp 621 for attaching Velcro, and the other quick-change module 62 is equipped with a sponge suction cup 622 for attaching card pockets. The robotic arm 61 switches between different quick-change modules 62 through quick-change connectors to complete the attachment of Velcro and card pockets.

[0022] In this embodiment, the frame 1 is constructed using a welded steel structure or an aluminum profile frame to provide stable support for the entire device; the conveying mechanism 2 uses parallel rollers or a continuous conveyor belt to transport the coffered box from the loading end to the processing station.

[0023] The blocking mechanism 31 uses a cylinder-driven baffle, which stops when the enclosure box reaches the preset position; the edge positioning mechanism 32 uses a cylinder-driven push rod, which can push the enclosure box towards a fixed reference edge to complete the lateral positioning. The two work together to achieve bidirectional precise positioning of the enclosure box in the horizontal plane, providing a stable processing benchmark for subsequent processes.

[0024] The suction cup assembly 41 uses multiple independent sponge suction cups 622, and the downward driving component 42 uses an electric push rod or a pneumatic cylinder. During operation, the suction cup assembly 41 moves downward to adsorb the window surface of the enclosure box to be opened, and then moves upward to lift it, so that the window surface to be opened is kept in a horizontal tension state, eliminating board warping and ensuring laser cutting accuracy.

[0025] The gantry moving mechanism 51 drives the laser cutting head 52 to move along a preset cutting trajectory in the horizontal plane through a parallel guide rail, crossbeam and servo screw transmission system; the laser cutting head 52 can be adapted to adjust the spot size and output power, and completes non-contact cutting and opening of the window surface of the enclosure box through a high-energy laser beam.

[0026] One set of quick-change modules 62 is equipped with a folding clamp 621 for attaching Velcro, which can grasp the Velcro and attach it after folding. Another set of quick-change modules 62 is equipped with a sponge suction cup 622 for attaching card pockets, which can smoothly pick up and attach card pockets. The robotic arm 61 automatically switches between the two sets of quick-change modules 62 via a quick-change connector to complete the automated attachment operation for different materials. In addition, a fence is set up in the working area of ​​the attachment component 6 to ensure the safety of the robotic arm 61 during operation.

[0027] This device adopts an integrated design, combining the positioning, leveling, window opening, and attachment processes of the enclosure box into a continuous automated processing flow, which greatly improves processing efficiency and avoids the safety hazards of manual operation. At the same time, through precise positioning, laser cutting, and quick-change robotic arm operation, it ensures processing quality and multi-task execution efficiency, solving the problems of low efficiency and high safety risks of existing technologies.

[0028] As a preferred embodiment of the above, the blocking mechanism 31 includes two roller rows 311, a blocking plate 312 and a linear drive assembly 313; the two roller rows 311 are spliced ​​at the conveying end of the conveying mechanism 2, the blocking plate 312 is disposed between the two roller rows 311, and the linear drive assembly 313 is used to drive the blocking plate 312 to move in the opposite direction along the parallel conveying direction to push the enclosure box to a preset position.

[0029] Specifically, each roller row 311 consists of several rollers arranged side by side, forming a low-friction support surface to support the pallet box being transported to its designated position, ensuring smooth and unbiased movement. The roller rows 311 can employ a non-powered free roller structure or a powered drive roller structure to assist in the end-of-line transport and docking of the pallet box. A baffle plate 312 is located between two roller rows 311 and serves as a rigid limiting component. It is made of metal or high-strength plastic sheet, and its contact surface with the pallet box can be reinforced with a rubber or polyurethane cushioning layer to provide initial physical restraint and prevent the pallet box from exceeding its preset working position range.

[0030] The output end of the linear drive assembly 313 is connected to the blocking plate 312 for transmission. It drives the blocking plate 312 to move linearly back and forth in the opposite direction to the conveying direction of the conveying mechanism 2. By pushing the enclosure box in the reverse direction, it finely adjusts the enclosure to the preset positioning position in the conveying direction. The linear drive assembly 313 can be a ball screw mechanism driven by a servo motor to achieve high-precision displacement control of the blocking plate 312; or it can be a cylinder or hydraulic cylinder with position sensor feedback, which drives the piston rod to extend and retract by controlling the pressure medium, thereby driving the blocking plate 312 to complete the linear pushing action.

[0031] During operation, the enclosure box is conveyed by the conveyor mechanism 2 to the roller row 311 at the end. The blocking plate 312 first limits the forward stroke of the enclosure box, and then the linear drive assembly 313 drives the blocking plate 312 to move in the opposite direction along the conveying direction, accurately pushing the enclosure box to the preset positioning position in the conveying direction. Together with the edge positioning mechanism 32, the enclosure box is accurately positioned in both directions in the horizontal plane, which effectively solves the problems of insufficient positioning accuracy and poor stability of the enclosure box. It provides an accurate positioning benchmark for subsequent laser window opening and labeling operations, ensures the accuracy of the window opening position and the neatness of the labeling, and improves the overall processing quality and operation efficiency.

[0032] In this invention, the edge positioning mechanism 32 includes two pusher plates 321 and a pusher assembly 322; the pusher assembly 322 is fixed on the frame 1, and the pusher plates 321 are disposed between adjacent rollers of the conveying mechanism 2; the upper end of the pusher plate 321 can extend out of the conveying plane of the conveying mechanism 2; the pusher assembly 322 is used to drive the pusher plate 321 to move along a direction perpendicular to the conveying direction, so as to push the enclosure box to the fixed grid 323 on the frame 1.

[0033] Two pusher plates 321 are symmetrically arranged, each located in the gap between adjacent rollers of the conveying mechanism 2. The upper end of the pusher plate 321 always extends above the conveying plane of the conveying mechanism 2. This layout makes full use of the idle space between the rollers of the conveying mechanism 2, completely avoiding motion interference between the pusher plate 321 and the conveying rollers. At the same time, it ensures that the pusher plate 321 can form a stable and effective contact with the side of the conveyed enclosure box, providing a reliable force application point for the pushing action and structurally eliminating the problems of poor contact and slippage during the pushing process.

[0034] The pusher plate 321 is a rigid plate-shaped component. A low-friction wear-resistant layer or an elastic buffer layer can be added to the contact surface with the enclosure box. This ensures that a uniform pushing force is applied to the enclosure box during the pushing process, preventing the box from deflecting due to single-point force, and also prevents scratches on the surface of the enclosure box, thus protecting the integrity of the product's appearance.

[0035] The output end of the pusher drive assembly is fixedly connected to two pusher plates 321, and is used to drive the two pusher plates 321 to move synchronously in a linear reciprocating motion in a direction perpendicular to the conveying direction of the conveying mechanism 2. The pusher drive assembly can adopt a cylinder, hydraulic cylinder, or a linear drive structure of servo motor combined with ball screw and gear rack, which can output a stable and controllable lateral thrust and accurately control the moving stroke of the pusher plate 321 to ensure the accuracy of lateral positioning.

[0036] At the end of the pushing stroke of the pusher plate 321 on the frame 1, there is a fixed guard 323 parallel to the conveying direction of the conveying mechanism 2. The fixed guard 323 is a rigid limiting reference surface that has been precisely calibrated, serving as a unified reference for the lateral positioning of the enclosure box.

[0037] During operation, after the enclosure box is conveyed to the positioning station by the conveying mechanism 2, the pushing drive assembly drives the two pushing plates 321 to move synchronously to the side of the fixed grid 323. The pushing plates 321 extending out of the conveying plane apply symmetrical and uniform lateral pushing force to the enclosure box, and push the enclosure box smoothly to its side to fit tightly against the fixed grid 323, thus completing the high-precision positioning of the enclosure box in the direction perpendicular to the conveying direction. In conjunction with the blocking mechanism 31, it achieves bidirectional precise positioning of the enclosure box in the horizontal plane.

[0038] This solution, through the symmetrical force application structure of the double pusher plates 321, effectively avoids the deflection of the enclosure box during the pusher positioning process, significantly improving the stability and reliability of lateral positioning. The layout of the pusher plates 321, located between adjacent rollers and with their upper ends always extending out of the conveying plane, avoids motion interference with the conveying mechanism 2 and ensures effective contact with the enclosure box throughout the entire process, eliminating the risk of pusher failure. Precise bidirectional positioning provides a stable and unified processing benchmark for subsequent laser windowing and bonding operations, effectively improving the overall processing accuracy and operating efficiency of the machine, and reducing the product defect rate caused by positioning deviation.

[0039] In a preferred embodiment of the present invention, there are two sets of suction cups 41, which are respectively located on both sides of the window opening position of the enclosure box; the downward driving component 42 drives the two sets of suction cups 41 to move down synchronously to press and adsorb the window surface to be opened, and then moves up to lift so that the window surface to be opened is kept in a horizontal tension state.

[0040] Specifically, two sets of suction cups 41 are respectively located on both sides of the window opening station of the enclosure box, and the distance between the two sets of suction cups 41 is greater than the width of the window to be processed on the window surface.

[0041] The suction cup assembly 41 is connected to the vacuum generator and adopts an integral sponge suction cup 622 structure with a large adsorption area, which can be adapted to the surface of the enclosure box with different surface roughness to achieve stable negative pressure adsorption.

[0042] The downward drive component 42 is connected to the two suction cup groups 41 for transmission, and is used to drive the two suction cup groups 41 to complete the lifting action synchronously. The downward drive component 42 can be a cylinder, a hydraulic cylinder, or a high-precision linear drive structure with a servo motor and a ball screw or gear rack; the motion synchronization of the two suction cup groups 41 can be ensured by a synchronous controller or a coaxial transmission structure, and force sensors and displacement sensors can also be equipped to accurately control the lifting stroke and force of the suction cup groups 41.

[0043] During operation, the downward driving component 42 drives the two sets of suction cups 41 to move downwards synchronously, so that the suction cups are in close contact with the window surface to be opened in the enclosure box and apply pre-pressure. The suction cups 41 then activate negative pressure to adsorb and fix the window surface to be opened. After adsorption is completed, the downward driving component 42 drives the two sets of suction cups 41 to move upwards synchronously and lift them up. The adsorption force distributed symmetrically on both sides applies uniform tension to the window surface to be opened, keeping the window surface to be opened in a horizontal and taut flat state, and completely eliminating defects such as warping and wrinkles on the board surface.

[0044] This solution utilizes a symmetrically arranged double suction cup group 41 structure on both sides of the window opening station to evenly distribute the adsorption force, effectively avoiding stress concentration and board surface deformation caused by single-point or unilateral adsorption. The distance between the two suction cup groups 41 is greater than the window width, completely avoiding interference between the adsorption area and the laser cutting area, ensuring the continuity of the cutting operation. Through synchronous downward adsorption and synchronous upward lifting actions, the tilting and displacement of the panel box during the pressing and leveling process are effectively prevented, providing a flat, stable, and deformation-free processing plane for subsequent laser window opening. This significantly improves the window accuracy and processing quality of laser cutting and reduces the product defect rate.

[0045] In a preferred embodiment of the present invention, the laser window opening assembly 5 further includes a lifting drive assembly 53, a laser displacement sensor 54, and a visual positioning unit 55; the lifting drive assembly 53 is used to drive the laser cutting head 52 to move vertically to a set cutting height, the laser displacement sensor 54 is used to detect the vertical distance from the laser cutting head 52 to the surface to be cut, and the visual positioning unit 55 is used to collect the point information of the area to be cut in order to adjust the cutting trajectory and position.

[0046] The lifting drive assembly 53 is connected to the laser cutting head 52 for transmission, and is used to drive the laser cutting head 52 to perform high-precision linear reciprocating movement in the vertical direction, adjusting the laser cutting head 52 to the set cutting height, and ensuring that the laser focus is always at the optimal cutting position on the surface to be cut. The lifting drive assembly 53 can adopt a ball screw mechanism driven by a servo motor, a linear guide system driven by a linear motor, or a structure of pneumatic / hydraulic cylinders combined with precision guides, which can accurately control the lifting stroke and positional accuracy of the laser cutting head 52.

[0047] The laser displacement sensor 54 is installed synchronously with the laser cutting head 52. It is a non-contact, high-precision ranging component used to detect the vertical distance from the laser cutting head 52 to the surface to be cut in real time. It can measure distance based on laser triangulation or laser time-of-flight method, and can quickly respond to local undulations and thickness differences of the surface to be cut. It feeds back the real-time distance data to the control system, providing closed-loop feedback for the dynamic height adjustment of the lifting drive component 53, and ensuring the consistency of the cutting depth throughout the entire cutting process.

[0048] The visual positioning unit 55 is fixedly installed on the gantry moving mechanism 51 and connected to the control system signal. It is a positioning system integrating image acquisition, image processing and feature recognition functions. It is used to collect the point information of the area to be cut in order to correct and adjust the cutting trajectory and cutting position. The cofferdam box to be processed has pre-processed indentations, and the indentation trajectory has preset detection points. The visual positioning unit 55 can acquire images of the cofferdam box through an industrial camera, identify the detection points and plate edge features on the indentation trajectory, calculate the actual position and posture deviation of the area to be cut, generate the corrected cutting trajectory and send it to the gantry moving mechanism 51, effectively correcting the cutting position error caused by the placement deviation of the cofferdam box or the deformation of the plate surface.

[0049] During operation, the visual positioning unit 55 first collects the point information of the area to be cut and completes the pre-correction of the cutting trajectory; the laser displacement sensor 54 detects the vertical distance between the laser cutting head 52 and the surface to be cut in real time, and the control system drives the lifting drive component 53 to move the laser cutting head 52 in the vertical direction according to the detection data, and accurately adjusts it to the set cutting height; during the cutting process, the laser displacement sensor 54 continuously feeds back distance data to realize dynamic real-time compensation of the cutting height, and the gantry moving mechanism 51 drives the laser cutting head 52 to move according to the corrected cutting trajectory to complete the high-precision laser cutting and windowing.

[0050] This solution, through the coordinated operation of the lifting drive component 53, the laser displacement sensor 54, and the vision positioning unit 55, achieves precise control and dynamic compensation of the cutting height, as well as precise positioning and adaptive correction of the cutting trajectory. It effectively overcomes the cutting errors caused by unevenness of the panel box surface, placement deviation, and panel deformation, significantly improves the positional accuracy of laser window opening, the consistency of cutting depth, and the reliability of processing, reduces the product defect rate, and further enhances the automation level and production efficiency of the device.

[0051] Based on the above embodiment, universal balls 56 are symmetrically arranged on both sides of the laser cutting head 52, and the bottom contact surfaces of the two universal balls 56 are lower than the laser emitting end of the laser cutting head 52; the laser cutting head 52 is floatingly mounted on the execution end of the lifting drive assembly 53 in the vertical direction.

[0052] The symmetrically arranged universal balls 56 on both sides of the laser cutting head 52 are spherical components capable of rolling freely in any direction. They typically consist of a main ball and multiple smaller support balls, mounted within a bracket. Their characteristics include low friction, providing multi-directional support and guidance. One implementation involves the universal balls 56 being fixed to the brackets on both sides of the laser cutting head 52 via threads or clips, with the brackets rigidly connected to the laser cutting head 52 body. Another implementation integrates the universal balls 56 into the outer shell or protective cover of the laser cutting head 52, allowing for slight floating within a certain range via internal springs or flexible connectors to better adapt to uneven surfaces. The primary function of the universal balls 56 here is to provide contact points with the surface of the enclosure box for height sensing and support.

[0053] Simultaneously, the bottom contact surfaces of the two omnidirectional balls 56 are lower than the laser emitting end of the laser cutting head 52. The bottom contact surface refers to the lowest point where the omnidirectional ball 56 contacts the surface of the enclosure box, and the laser emitting end refers to the end of the component in the laser cutting head 52 that actually emits the laser beam. This feature ensures that the omnidirectional balls 56 contact the workpiece surface before the laser emitting end contacts the workpiece. This can be achieved by precisely designing the installation position of the omnidirectional balls 56 and the structure of the laser cutting head 52, so that the lowest point of the omnidirectional balls 56 is lower than a preset safe distance from the laser emitting end in the vertical direction. Alternatively, the mounting bracket of the omnidirectional balls 56 can be designed with an adjustable height mechanism, such as by screw adjustment or shim adjustment, to ensure that its bottom contact surface is always lower than the laser emitting end. This design aims to form a physical protective barrier to prevent the laser emitting end from directly colliding with the workpiece and to preset a safe working distance between the laser cutting head 52 and the workpiece.

[0054] Furthermore, the laser cutting head 52 is vertically floating at the actuation end of the lifting drive assembly 53. Floating installation means that the laser cutting head 52 is not rigidly fixed, but has a certain range of motion in the vertical direction, capable of making slight up-and-down displacements based on external contact forces or surface undulations. This installation method is typically achieved through elastic elements or flexible connections. For example, the laser cutting head 52 can be connected to the actuation end of the lifting drive assembly 53 via a set of springs or cylinders, which provide a downward preload while allowing the laser cutting head 52 to float upwards when encountering resistance. Alternatively, a magnetic levitation or flexible guide rail structure can be used, giving the laser cutting head 52 low-friction floating capability in the vertical direction, which can be fine-tuned via sensor feedback. This floating installation allows the laser cutting head 52 to automatically adapt to the unevenness of the workpiece surface, maintaining a constant distance from the workpiece and ensuring cutting quality.

[0055] The symmetrically arranged omnidirectional balls 56 provide stable support and guidance as the laser cutting head 52 moves, preventing tilting or deviation of the cutting head and maintaining the accuracy of the cutting trajectory. The design of the bottom contact surface of the omnidirectional balls 56 being lower than the laser emitter allows them to contact the surface of the enclosure box before the laser emitter contacts the workpiece, forming a physical protective barrier that effectively protects the laser emitter from direct impact or wear, while also pre-setting and maintaining a safe cutting height between the laser emitter and the workpiece. Furthermore, the vertically floating installation of the laser cutting head 52 allows it to automatically adjust up and down according to minor undulations or unevenness on the enclosure box surface, adapting to workpiece deformation through an elastic buffer mechanism, thereby maintaining a constant distance between the laser emitter and the surface to be cut throughout the cutting process. This ensures that laser energy is applied evenly to the material, significantly improving cutting accuracy and quality, extending the service life of the laser cutting head 52, and enhancing the reliability and safety of the entire window-opening operation. By combining the laser displacement sensor 54 and the vision positioning unit 55 to precisely adjust the cutting height and position, this solution further enhances the adaptability to complex workpiece surfaces and ensures efficient and high-quality window opening operations.

[0056] In a preferred embodiment of the present invention, the attachment component 6 further includes a card bag peeling mechanism and a Velcro peeling mechanism. The card bag peeling mechanism is located at the card bag feeding station and includes a peeling blade 63, a clamping arm 64, and a paper peeling drive component 65, used to peel the release paper from the card bag. Specifically, the peeling blade 63 is a plate-shaped component with a sharp-angled peeling blade at the front end, fixedly installed at the end of the material conveying path at the card bag feeding station, with its peeling blade facing the card bag feeding direction, serving as a folding angle support and limiting component for the release paper peeling, and achieving folding angle separation guidance between the release paper and the card bag body through the sharp-angle structure. The clamping arm 64 is an openable clamping component used to stably clamp the end part of the card bag release paper, and can adopt a pneumatic gripper or electric gripper structure, so that the clamping process will not damage the release paper and the card bag body. The paper-peeling drive unit 65 is the power unit for the peeling operation. Its actuator is fixedly connected to the clamping arm 64 and is used to drive the clamping arm 64 to move linearly back and forth along a set path. The paper-peeling drive unit 65 can adopt a stepper motor, a servo motor with a linear module, or a cylinder or hydraulic cylinder structure, which can precisely control the peeling stroke and peeling speed. During operation, the peeling blade 63 works in concert with the clamping arm 64 and the paper-peeling drive unit 65 to complete the peeling of the release paper.

[0057] The hook and loop fastener peeling mechanism is located at the hook and loop fastener loading station and includes an unwinding shaft 66, a peeling platform 67, and a rewinding shaft 68, used to peel off the release paper from the hook and loop fastener. The peeling platform 67 is located between the unwinding shaft 66 and the rewinding shaft 68, providing a flat, low-friction support surface for the hook and loop fastener peeling operation. It is made of a smooth metal or engineering plastic plate and can be equipped with guide grooves and guide wheel structures to constrain the travel path of the hook and loop fastener.

[0058] During operation, at the card bag loading station, the card bags to be peeled are conveyed to the peeling knife 63. The release paper end of the card bag completes the initial angle separation along the acute angle peeling edge of the peeling knife 63. The clamping arm 64 closes to hold the separated release paper end. The paper peeling drive 65 drives the clamping arm 64 to move in the opposite direction to the card bag body conveying direction. With the fixed limit support of the peeling knife 63, the release paper is completely and smoothly peeled from the adhesive side of the card bag, preparing for the card bag attaching operation of the robotic arm 61. At the hook and loop fastener loading station, the unwinding shaft 66 continuously unwinds the hook and loop fastener roll with release paper. The hook and loop fastener completes the continuous separation of release paper and hook and loop fastener body through the peeling angle of the peeling platform 67. The peeled hook and loop fastener body stays on the peeling platform 67 for the robotic arm 61 to grab. The separated waste release paper is simultaneously wound up and stored by the rewinding shaft 68.

[0059] This solution achieves fully automated release liner removal before bonding by setting up dedicated card bag peeling and hook and loop fastener peeling mechanisms for the bonding operation. This eliminates the need for manual intervention, avoiding the problems of low efficiency, incomplete peeling, and operational risks associated with manual peeling, and significantly improving the automation level and production efficiency of the bonding operation. Specifically, the card bag peeling mechanism, through the coordinated action of the peeling blade 63's angled guide, the clamping arm 64's stable gripping, and the power traction of the peeling drive component 65, achieves complete and damage-free peeling of the release liner without cutting, ensuring the structural integrity of the card bag itself. The hook and loop fastener peeling mechanism, with its roll-to-roll continuous peeling structure, adapts to the feeding requirements of roll-type hook and loop fasteners, achieving uninterrupted automatic peeling of the release liner. The two peeling mechanisms ensure the cleanliness and integrity of the card bag and hook and loop fastener adhesive surfaces throughout the process, improving the final bonding quality and adhesion strength, reducing the product defect rate caused by improper peeling, and realizing fully automated operation from material feeding and release liner peeling to automatic bonding, further optimizing the overall machine's operating efficiency and processing stability.

[0060] In a preferred embodiment of the present invention, the folding clamp 621 includes a mounting base 6211, two needle-punching clamps 6212, and a gripper drive assembly 6213; the two needle-punching clamps 6212 are symmetrically hinged to the mounting base 6211, and the gripper drive assembly 6213 is used to drive the two needle-punching clamps 6212 to rotate synchronously, so that the material picking surfaces of the two needle-punching clamps 6212 change from a coplanar material picking state to a relatively parallel folding and attaching state.

[0061] Two needle-punching clamps 6212 are rotatably connected to the mounting base 6211 via hinge pins, and can rotate around the hinge pin within a preset angle range. Each needle-punching clamp 6212 has a retractable needle on its picking surface. During picking, the needle extends to pierce and fix the hook and loop fastener, preventing the hook and loop fastener from shifting or falling off during picking and folding. During attaching, the needle can be retracted to release the piercing limit on the hook and loop fastener.

[0062] The gripper drive assembly 6213 is mounted on the mounting base 6211, and its output end is connected to the two needle-punching grippers 6212 for driving the two needle-punching grippers 6212 to rotate synchronously. The gripper drive assembly 6213 can adopt a linkage structure of micro servo motor and synchronous gear set to achieve synchronous rotation of the two needle-punching grippers 6212 at the same speed and angle through a single drive source; it can also adopt a cylinder with a double rocker linkage mechanism, or two independently controlled micro drive units with an electronic control synchronization system to precisely control the rotation angle and rotation speed of the two needle-punching grippers 6212.

[0063] Driven by the gripper drive assembly 6213, the material-taking surfaces of the two needle-punched clamps 6212 can achieve precise switching between two working states: one is a coplanar material-taking state, that is, the material-taking surfaces of the two needle-punched clamps 6212 are in the same plane, which is suitable for the material-taking requirements of the Velcro in a flat state; the other is a relatively parallel folded attachment state, that is, after the two needle-punched clamps 6212 rotate synchronously around the hinge axis, their material-taking surfaces are parallel to each other and set opposite to each other. The distance between them is adapted to the thickness of the folded plate of the panel box, and they can be clamped on both sides of the inner and outer walls of the folded plate to simultaneously complete the folding and forming of the Velcro.

[0064] During operation, the gripper drive assembly 6213 first drives the two needle-punching grippers 6212 to rotate to a material-picking state where the picking surfaces are coplanar. The needles of the needle-punching grippers 6212 extend and pierce the mortise surface of the Velcro roll after the release paper is peeled off, completing the flat picking of the Velcro. The robotic arm 61 drives the folding gripper 621 to move to the folding position formed by the window of the enclosure box. The gripper drive assembly 6213 drives the two needle-punching grippers 6212 to rotate synchronously, bringing the two picking surfaces closer to each other until the two needle-punching grippers 6212 reach their picking position. The material is clamped on the inner and outer walls of the corner of the folding plate. At this time, the hook and loop fastener is precisely folded and attached to the corner of the folding plate as the needle clamp 6212 rotates. Then, the needle of the needle clamp 6212 retracts, releasing the piercing and fixing of the hook and loop fastener. The robotic arm 61 drives the two needle clamps 6212 to move along the surface of the folding plate away from the corner of the folding plate. Using the clamping force of the two needle clamps 6212 on the folding plate, the remaining part of the hook and loop fastener is completely smoothed and pressed onto the surface of the folding plate, completing the folding and attaching operation of the hook and loop fastener.

[0065] This solution utilizes a symmetrically hinged double-needle clamp 6212 structure, coupled with the synchronous drive of the gripper drive component 6213, to automate the switching between flat material picking and precise folding of the Velcro. This effectively avoids wrinkles and misalignment issues that occur during the folding process, ensuring consistency and positional accuracy in each fold and attachment. Simultaneously, through the extension and retraction of the needles and the clamping and smoothing action design, the entire process of Velcro material picking, folding, attachment, and compaction is automated. This significantly improves the efficiency and adhesion of Velcro attachment, avoids operational errors and safety risks associated with manual folding and attachment, reduces labor intensity, and further enhances the overall automation level of the machine.

[0066] As a preferred embodiment of the above, the device further includes an isolation plate 7; the robotic arm 61 grasps the isolation plate 7 through a quick-connect coupling and inserts the isolation plate 7 below the surface to be cut of the enclosure box to isolate the non-processed surface of the enclosure box.

[0067] The isolation plate 7 is a plate-shaped component that is resistant to high temperatures and thermal deformation. It can be made of metals such as stainless steel and aluminum alloy, or ceramics and high-temperature resistant composite materials. Its thickness and external dimensions are designed to fit the internal structure of the enclosure box and the size of the window to be cut. It can be made of rigid plate to provide stable barrier protection, or it can be made of thin plate with a certain degree of flexibility to adapt to the insertion operation in the narrow internal cavity of the enclosure box, ensuring that the isolation plate 7 can completely cover the window area of ​​the surface to be cut, forming a comprehensive physical barrier. The isolation plate 7 is equipped with a standardized docking and locking structure that is compatible with the quick-change connector at the end of the robotic arm 61. It can quickly dock, lock and release with the quick-change connector. It shares the same quick-change interface with the quick-change module 62 corresponding to Velcro and card pockets, without the need for additional docking mechanisms.

[0068] The robotic arm 61 can be a six-axis industrial robot, a SCARA robot, or a Cartesian coordinate robot, and has multi-degree-of-freedom high-precision motion control capabilities. It can automatically grasp, move, insert, and remove the isolation plate 7 through quick-change connectors.

[0069] This solution, by adding an isolation plate 7, effectively solves the problems of high-temperature molten slag, heat radiation, and cutting fumes that can easily damage and contaminate the non-machined surfaces of the enclosure box during laser cutting. The isolation plate 7 forms a reliable physical barrier during cutting operations, preventing defects such as heat deformation, scorching, and surface contamination on non-machined surfaces, significantly improving the product's processing quality and appearance integrity. Simultaneously, relying on the robotic arm 61 and the existing quick-change connector, the fully automated, high-precision deployment and removal of the isolation plate 7 is achieved without manual intervention. This seamlessly integrates with the automated operation process of the entire machine, improving production efficiency while ensuring the consistency and reliability of the isolation protection position each time, avoiding the safety risks and positioning errors of manual operation.

[0070] In a preferred embodiment of the present invention, the device further includes a fumigation hood 8 and a fan. The fumigation hood 8 is mounted on the pusher plate 321 of the edge positioning mechanism 32, and the fan is connected to the fumigation hood 8 to draw out the smoke generated during the laser cutting process.

[0071] The fume hood 8 adopts a strip-shaped box structure or a funnel-shaped gas collection structure adapted to the installation size of the pusher plate 321. Its gas collection port is set facing the laser cutting area. It can be equipped with an adjustable-angle hinged bracket and a telescopic connecting structure to connect with the pusher plate 321 to adapt to the gas collection needs of different cutting positions. The fume hood 8 is fixedly installed on the pusher plate 321 of the edge positioning mechanism 32. It relies on the structural strength of the pusher plate 321 itself to provide stable support, without the need for additional independent mounting brackets, thus simplifying the equipment structure. At the same time, it can move synchronously with the pusher plate 321. After the enclosure box completes the edge positioning, the fume hood 8 can move close to the laser cutting operation area synchronously with the pusher plate 321 to achieve close-range capture of the smoke source.

[0072] The fan provides negative pressure for smoke extraction. Centrifugal fans, axial fans, and other types that meet the air volume requirements can be selected. The air inlet of the fan is connected to the air outlet of the smoke hood 8 through a pipeline system. The pipeline can be a flexible corrugated pipe to adapt to the movement requirements of the pusher plate 321, or a rigid pipe can be used to provide a stable airflow channel, ensuring that the negative pressure generated by the fan can stably act on the air collection port of the smoke hood 8 to form a continuous suction airflow.

[0073] During operation, after the pusher plate 321 of the side positioning mechanism 32 pushes the enclosure box to complete the lateral positioning, the air collection port of the fume hood 8 faces the window operation area of ​​the laser cutting. At the same time as the laser window opening operation starts, the fan starts simultaneously, forming a local negative pressure environment inside the fume hood 8, which quickly captures the smoke and harmful gases generated during the laser cutting of the enclosure box from the source, and pumps them to the external purification system through the pipeline system to prevent the smoke from spreading to the working environment.

[0074] This solution integrates the fume hood 8 onto the pusher plate 321 of the edge positioning mechanism 32, fully utilizing the positioning stroke and working position of the pusher plate 321. This allows the fume hood 8 to synchronously approach the smoke source along with the pusher plate 321, significantly improving smoke collection efficiency. No additional independent drive and positioning mechanism is needed for the fume hood 8, resulting in a more compact and integrated equipment structure. Through the coordinated operation of the fume hood 8 and the fan, the smoke generated by laser cutting can be quickly extracted, ensuring a clean working environment and protecting the health of operators. It also prevents smoke and dust from adhering to and contaminating the optical components of the laser cutting head 52, effectively ensuring laser cutting accuracy, extending the service life of core components, and improving the stability and safety of the open-window operation.
