Description

Technical Field

[0001] This invention relates to the technical field of multi-layer composite heat dissipation shielding cover production equipment, specifically a dust-free lamination assembly device and method with real-time particle monitoring. Background Technology

[0002] Multi-layer composite shielding covers are industrial composite components that combine heat dissipation and electromagnetic shielding functions. They employ a multi-layered, heterogeneous material stacked composite structure, achieving both efficient heat conduction and electromagnetic signal blocking. Composed of stacked functional layers, commonly a combination of a metal layer, a thermally conductive interface layer, and a shielding layer, they are firmly bonded through intermetallic compounds, balancing low density and high strength. They can rapidly dissipate heat through the high thermal conductivity layer while blocking electromagnetic signal leakage through the metal shielding layer, enhancing air convection heat dissipation without significantly reducing shielding effectiveness.

[0003] Multi-layer composite heat dissipation shielding covers require a high level of cleanliness in the production environment when they are stacked and pressed together. If free microparticles are present in the environment during the stacking process, they will embed between the functional layers and cause bulging and delamination on the surface of the components during pressing, which will damage the bonding strength and shielding performance, increase thermal resistance, and ultimately significantly reduce the product yield.

[0004] In existing technologies, multi-layer composite shielding cover lamination equipment relies solely on the overall cleanroom system to maintain cleanliness, or uses multiple independent air shower units to blow clean the work space. It cannot monitor the particle concentration in the lamination work area in real time, nor can it quickly remove and detect residual particles on the surface of the functional layers to be laminated. This can easily lead to a high defect rate of finished products due to particle residue, making it difficult to meet the mass production requirements of high-precision and high-reliability multi-layer composite components. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dust-free lamination assembly device with real-time particle monitoring. This solves the problem that multi-layer composite shielding cover lamination equipment cannot monitor the particle concentration in the lamination operation area in real time, nor can it quickly remove and detect residual particles on the surface of the functional layers to be bonded. As a result, particle residue can easily lead to a high defect rate in finished products, making it difficult to meet the mass production requirements of high-precision and high-reliability multi-layer composite components.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleanroom lamination assembly device with real-time particle monitoring, comprising a base, two first linear motors mounted on the top of the base, each with a material transfer suction cup at its output end, and a second linear motor mounted on the top of the base on the side of the first linear motors away from each other. The cleanroom lamination assembly device with real-time particle monitoring also includes a hopper assembly, of which two sets are arranged, distributed on the side of the second linear motors away from the first linear motors; a feeding assembly is located on the side of the hopper assembly closer to the second linear motors; a lamination assembly is located on top of the output end of the second linear motors; and a dust removal assembly is located above the second linear motors. The hopper assembly stores stacked workpieces to be laminated, and after receiving the workpieces through the feeding assembly, moves them to the top of the lamination assembly. The second linear motor drives the lamination assembly and the workpieces to be laminated to move. After dust removal and detection by the dust removal assembly, subsequent lamination processing steps are performed.

[0007] Preferably, the hopper assembly includes a pull-out plate, with two sets of pull-out plates slidably connected to the top of the base on the side of the second linear motor away from the first linear motor; a lifting plate is located on the top of the pull-out plate; multiple limiting plates are fixedly connected to the top of the pull-out plate on the outside of the lifting plate; through-beam photoelectric sensors are fixedly connected to the top of the base on both sides of the pull-out plate; and a locking module is located on one side of the pull-out plate. The top of the lifting plate has workpieces to be laminated stacked on it, and the multiple limiting plates surround the sides of the workpieces to limit their movement. The through-beam photoelectric sensors detect the position of the top workpiece, controlling the lifting drive device of the lifting plate to keep the topmost workpiece at a specified height. The locking module locks the position of the pull-out plate.

[0008] Preferably, the locking module includes a first servo cylinder, which is fixedly connected to the top of the base on one side of the pull-out plate; a locking block is fixedly connected to the output end of the first servo cylinder and is also connected to the inner wall of the pull-out plate; wherein, the first servo cylinder drives the locking block to move up and down and insert it into the corresponding positioning groove on the side of the pull-out plate to achieve the limiting and locking of the pull-out plate.

[0009] Preferably, the feeding assembly includes a feeding robot, which is positioned on one side of the two pull-out plates near the first linear motor; a first gripping suction cup is positioned at the output end of the feeding robot; a film-tearing module is positioned on one side of the first gripping suction cup; a transfer platform is fixedly connected to the top of the base at the end of the second linear motor away from the first linear motor; and a material transfer assembly is positioned on one side of the second linear motor and the transfer platform. The feeding robot moves the first gripping suction cup to grip the workpiece to be laminated on the top layer of the hopper assembly, places the workpiece on the transfer platform for film-tearing, and then the material transfer assembly transfers the workpiece from the transfer platform to the top of the laminating assembly.

[0010] Preferably, the material transfer assembly includes a first KK module, which is fixedly connected to the top of the base and located on one side of the second linear motor and the transfer table; a second KK module is fixedly connected to the output end of the first KK module; and a second gripping suction cup is installed at the output end of the second KK module. The first and second KK modules work together to move the second gripping suction cup, gripping and transferring the workpiece after the film has been peeled off from the transfer table, accurately placing the workpiece at the designated position of the laminating assembly.

[0011] Preferably, the lamination assembly includes a negative pressure box, which is fixedly connected to the output end of a second linear motor; a grid plate is disposed on the top of the negative pressure box; a pressure roller is disposed inside the negative pressure box; and a roller pressing drive assembly is disposed inside the negative pressure box at the bottom of the pressure roller. The negative pressure box uses the grid plate to perform negative pressure adsorption and fixation on the workpiece to be laminated. The roller pressing drive assembly drives the pressure roller to reciprocate inside the negative pressure box, applying pressure from the lower surface of the workpiece. Combined with the roller pressing drive assembly above the workpiece, the multi-layer workpiece is uniformly rolled.

[0012] Preferably, the roller pressing drive assembly includes two slide rails, which are fixedly connected to the inner sides of the negative pressure chamber; a servo motor is mounted on the outer wall of the negative pressure chamber; a synchronous belt is rotatably connected to the inside of the negative pressure chamber and is driven by the output end of the servo motor; a movable seat is slidably connected to the outer wall of the slide rails and fixedly connected to the outer wall of the synchronous belt; a second servo cylinder is fixedly connected to the bottom sides of the movable seat; a lifting seat is located above the movable seat, fixedly connected to the output end of the second servo cylinder, and rotatably connected to the pressure roller; wherein, the second servo cylinder drives the lifting seat to rise and fall, while the servo motor drives the synchronous belt to rotate, causing the movable seat to reciprocate, so that the pressure roller applies uniform pressure to the lower surface of the workpiece to be laminated.

[0013] Preferably, the dust removal assembly includes a particle counter, which is fixedly connected to the outer wall of the base and its output end is connected to the interior of the base; an ultrasonic dry cleaner is fixedly connected to the top of the base above the second linear motor; multiple vertical rods are provided, fixedly connected to the top of the base and spaced apart around the outer periphery of the pull-out plate; a plasma air nozzle is fixedly connected to the top of the vertical rod; and a detection assembly is located above the second linear motor on the side of the ultrasonic dry cleaner closer to the first linear motor. The particle counter is located at the junction of the workpiece cleaning and inspection process and the lamination assembly process to perform real-time sampling and monitoring of air particle concentration. After the first gripping suction cup adsorbs and grips the workpiece to be laminated, the plasma air nozzle sprays an ionized gas flow to eliminate static electricity on the workpiece surface. Simultaneously, when the workpiece passes through the ultrasonic dry cleaner under the influence of the negative pressure box, the ultrasonic dry cleaner performs dry cleaning on the workpiece surface, removing tiny particulate impurities attached to the workpiece surface.

[0014] Preferably, the detection component includes a mounting frame, which is positioned above the second linear motor and located on the side of the ultrasonic dry cleaner closer to the first linear motor; a CCD camera is fixedly connected to both sides of the outer wall of the mounting frame; and a coaxial light source is fixedly connected to the outer wall of the mounting frame and located at the bottom of the CCD camera. After the workpiece to be laminated is cleaned by the ultrasonic dry cleaner, it moves to the area below the CCD camera. The two CCD cameras, in conjunction with the coaxial light source, image and detect the surface of the workpiece, identify and count residual particles on the workpiece surface, and determine whether the cleanliness of the workpiece surface meets the processing requirements. Beneficial effects

[0015] This invention provides a cleanroom lamination assembly device with real-time particle monitoring. It offers the following advantages: Through the coordination of a base, a first linear motor, a material transfer suction cup, a second linear motor, a hopper assembly, a feeding assembly, a lamination assembly, and a dust removal assembly, this cleanroom lamination assembly utilizes ion air to eliminate static electricity on the workpiece surface during the transfer of the workpiece from the hopper to the lamination station. Simultaneously, ultrasonic dry cleaning removes tiny particles adhering to the workpiece surface, and imaging detection identifies residual particles. Furthermore, real-time monitoring of the ambient particle concentration within the entire device allows for timely adjustment of the exhaust and dust removal intensity. This ensures that the working environment and the laminated workpiece meet cleanroom processing requirements, preventing excess particles from adhering to the layers of the workpiece and causing impurities inside the laminated workpiece. This helps improve the lamination quality and reliability of multi-layer composite shielding covers, thereby meeting the mass production needs of high-precision, high-reliability multi-layer composite components.

[0016] Through the cooperation of the first linear motor, material transfer suction cup, negative pressure box, grid plate, pressure roller and rolling drive assembly, after the upper and lower workpieces are aligned and bonded, the material transfer suction cup presses down from the top of the laminated workpiece, and the pressure roller rolls down from the bottom of the laminated workpiece evenly from top to bottom. This can uniformly squeeze the stacked workpieces, thereby expelling the air between the two layers of workpieces, avoiding residual air bubbles between layers, making the workpieces bond more tightly and evenly, effectively improving the bonding strength of the multi-layer composite heat dissipation shielding cover laminate assembly, reducing the thermal resistance caused by interlayer gaps, and avoiding air bubbles and gaps from affecting the shielding effectiveness. This helps to further improve the performance stability and yield of the finished product. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In existing technologies, multi-layer composite shielding cover lamination equipment cannot monitor the particle concentration in the lamination operation area in real time, nor can it quickly remove and detect residual particles on the surface of the functional layer to be bonded. This can easily lead to a high defect rate of finished products due to particle residue, making it difficult to meet the mass production requirements of high-precision and high-reliability multi-layer composite components.

[0021] In view of this, the present invention provides a cleanroom lamination assembly device with real-time particle monitoring. Through the cooperation of the base, the first linear motor, the material transfer suction cup, the second linear motor, the hopper assembly, the feeding assembly, the lamination assembly, and the dust removal assembly, during the transfer of the workpiece to be laminated from the hopper to the lamination station, ion wind is used to eliminate static electricity on the workpiece surface, and ultrasonic dry cleaning is used to remove tiny particles attached to the workpiece surface. Imaging detection is used to identify residual particles, and the concentration of environmental particles inside the entire device is monitored in real time to adjust the exhaust and dust removal intensity in a timely manner. This ensures that the working environment and the laminated workpiece meet the requirements of cleanroom processing, avoids the adhesion of excess particles in the environment between the workpiece layers, which would cause impurities inside the laminated workpiece, improves the lamination bonding quality and product reliability of multi-layer composite shielding covers, and meets the mass production processing requirements of high-precision, high-reliability multi-layer composite components.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Depend on Figure 1-8 It is known that a dust-free lamination assembly device with real-time particle monitoring includes a base 1. Two first linear motors 2 are installed on the top of the base 1. Material transfer suction cups 3 are installed at the output ends of the first linear motors 2. A second linear motor 4 is installed on the top of the base 1 on the side of the first linear motors 2 that is far away from each other. The dust-free lamination assembly device with real-time particle monitoring also includes a hopper assembly 5, a feeding assembly 6, a lamination assembly 7, and a dust removal assembly 8. Two sets of hopper assemblies 5 are provided, distributed on the side of the second linear motor 4 that is far away from the first linear motors 2. The feeding assembly 6 is located on the side of the hopper assembly 5 that is close to the second linear motor 4. The lamination assembly 7 is located on the top of the output end of the second linear motor 4. The dust removal assembly 8 is located above the second linear motor 4. The hopper assembly 5 stores the stacked workpieces to be laminated. After receiving the workpieces through the feeding assembly 6, the workpieces are moved to the top of the lamination assembly 7. The second linear motor 4 drives the lamination assembly 7 and the workpieces to be laminated to move. After dust removal and detection by the dust removal assembly 8, the subsequent lamination processing steps are carried out. In the specific implementation process, it is worth noting that the base 1 provides a stable installation foundation for the entire cleanroom lamination assembly device and connects and fixes it with the upstream and downstream processes. Through the cooperation between the base 1, the first linear motor 2, and the material transfer suction cup 3, the workpiece processed in the previous process is adsorbed by the material transfer suction cup 3, and the workpiece is moved by controlling the first linear motor 2. The hopper assembly 5 is used to stack and store the workpieces to be laminated. The two hoppers located on the same side automatically switch to the other hopper to supply material after one hopper becomes empty, avoiding line stoppages due to waiting for material replenishment and ensuring the continuity of the multi-layer composite shielding cover lamination process. To ensure continuity and production efficiency, the second linear motor 4, hopper assembly 5, feeding assembly 6, and laminating assembly 7 work together. The feeding assembly 6 adsorbs the workpiece to be laminated in the hopper assembly 5 and transfers it to the laminating assembly 7. By controlling the second linear motor 4, the laminating assembly 7 moves the workpiece to be laminated below the first linear motor 2, aligning it with the upper workpiece transferred from the material transfer suction cup 3. After alignment, the lamination operation can begin. Before lamination, the dust removal assembly 8 eliminates static electricity on the workpiece surface using ion air and simultaneously removes tiny particles adhering to the workpiece surface using ultrasonic dry cleaning. Synthetic imaging identifies residual particles, while real-time monitoring of the ambient particle concentration within the entire device allows for timely adjustments to exhaust and dust removal intensity. This ensures the working environment consistently meets cleanroom processing requirements, preventing excess particles from adhering to the workpiece layers and causing impurities within the laminated workpiece, thus affecting the quality and performance of the finished product. Through the coordination of the base 1, first linear motor 2, material transfer suction cup 3, second linear motor 4, hopper assembly 5, feeding assembly 6, laminating assembly 7, and dust removal assembly 8, during the transfer of the workpiece from the hopper to the laminating station, ion wind eliminates static electricity on the workpiece surface, while ultrasonic waves are used. The dry cleaning method removes tiny particles adhering to the workpiece surface and uses imaging detection to identify residual particles. At the same time, the concentration of environmental particles inside the entire device is monitored in real time to adjust the exhaust dust removal intensity in a timely manner, ensuring that the working environment and laminated workpieces meet the requirements for dust-free processing. This avoids excess particles in the environment adhering between the workpiece layers, which would cause impurities inside the laminated workpiece. This improves the lamination quality and product reliability of multi-layer composite shielding covers, meeting the mass production processing needs of high-precision, high-reliability multi-layer composite components. The specific models of the first linear motor 2 and the second linear motor 4 are not limited, as long as they meet the usage requirements.

[0024] Furthermore, the hopper assembly 5 includes a pull-out plate 51, a lifting plate 52, a limiting plate 53, a through-beam photoelectric sensor 54, and a locking module 55. Two sets of pull-out plates 51 are slidably connected to the top of the base 1, located on the side of the second linear motor 4 away from the first linear motor 2. The lifting plate 52 is located on top of the pull-out plate 51. Multiple limiting plates 53 are fixedly connected to the top of the pull-out plate 51, located on the outer side of the lifting plate 52. The through-beam photoelectric sensor 54 is fixedly connected to the top of the base 1, located on both sides of the pull-out plate 51. The locking module 55 is located on one side of the pull-out plate 51. The top of the lifting plate 52 has workpieces to be laminated stacked on it. Multiple limiting plates 53 surround the sides of the workpieces to limit their movement. The through-beam photoelectric sensor 54 detects the position of the top workpiece, controlling the lifting drive of the lifting plate 52 to keep the topmost workpiece at a specified height. The locking module 55 locks the position of the pull-out plate 51. In the specific implementation process, it is worth noting that, through the cooperation of the pull-out plate 51, the lifting plate 52, the limiting plate 53, and the through-beam photoelectric sensor 54, the workpieces to be laminated are stacked on top of the lifting plate 52. Multiple limiting plates 53 surround the outside of the workpieces to limit their movement and prevent the stacked workpieces from tipping over or shifting. During the feeding process of the workpieces to be laminated, the through-beam photoelectric sensor 54 detects the position of the top layer workpiece in real time. When the top layer workpiece is removed, the through-beam photoelectric sensor 54 detects a shortage of material at the workpiece position and immediately sends a signal to the control system. The control system automatically controls the lifting drive device of the lifting plate 52 to drive... The lifting plate 52 lifts the remaining workpieces upwards, keeping the uppermost workpiece to be laminated at the material-retrieving height. After all the workpieces to be laminated in one hopper are removed, the control system automatically switches to another hopper for material supply and prompts the operator to replenish the empty hopper in a timely manner. The operator can quickly replenish the material by pulling out the pull plate 51. The locking module 55 automatically locks the pull plate 51 after it is inserted into place to prevent it from sliding or shifting during the material supply process and to ensure the accuracy of the feeding position. The specific model of the through-beam photoelectric sensor 54 is not limited, as long as it meets the usage requirements.

[0025] Furthermore, the locking module 55 includes a first servo cylinder 551 and a locking block 552. The first servo cylinder 551 is fixedly connected to the top of the base 1 on one side of the pull-out plate 51. The locking block 552 is fixedly connected to the output end of the first servo cylinder 551 and is connected to the inner wall of the pull-out plate 51. The first servo cylinder 551 drives the locking block 552 to move up and down and insert it into the corresponding positioning groove on the side of the pull-out plate 51 to achieve the limiting and locking of the pull-out plate 51. In the specific implementation process, it is worth noting that, through the cooperation between the pull plate 51, the first servo cylinder 551, and the locking block 552, after the pull plate 51 is inserted into place, the first servo cylinder 551 drives the locking block 552 to descend and insert into the corresponding positioning groove on the side of the pull plate 51, thereby locking the position of the pull plate 51 and preventing the pull plate 51 from sliding or shifting during the feeding process, ensuring that the feeding position is always accurate. After all the workpieces to be laminated in the hopper have been fed, the control system automatically controls the first servo cylinder 551 to drive the locking block 552 to move upward, releasing the limit on the pull plate 51 so that the staff can pull it out for replenishment. The specific model of the first servo cylinder 551 is not limited, as long as it meets the usage requirements.

[0026] Furthermore, the feeding assembly 6 includes a feeding robot 61, a first gripping suction cup 62, a film-tearing module 63, a transfer platform 64, and a material transfer assembly 65. The feeding robot 61 is located on the side of the two pull-out plates 51 near the first linear motor 2; the first gripping suction cup 62 is located at the output end of the feeding robot 61; the film-tearing module 63 is located on one side of the first gripping suction cup 62; the transfer platform 64 is fixedly connected to the top of the base 1 at the end of the second linear motor 4 away from the first linear motor 2; the material transfer assembly 65 is located on one side of the second linear motor 4 and the transfer platform 64. The feeding robot 61 drives the first gripping suction cup 62 to move, grips the workpiece to be laminated on the top layer of the hopper assembly 5, and places the workpiece on the transfer platform 64 for film-tearing operation. Then, the material transfer assembly 65 transfers the workpiece on the transfer platform 64 to the top of the lamination assembly 7. In the specific implementation process, it is worth noting that through the cooperation between the loading robot 61, the first gripping suction cup 62, the film-tearing module 63, the transfer platform 64, and the material transfer component 65, the loading robot 61 is controlled so that the first gripping suction cup 62 uses vacuum adsorption to adsorb and grip the workpiece to be laminated, and transfers the workpiece to the top of the transfer platform 64. The transfer platform 64 fixes the workpiece by vacuum adsorption. By controlling the loading robot 61 and the film-tearing module 63, the protective release film on the surface of the workpiece is peeled off. The peeled release film is collected and processed, and then the material transfer component 65 transfers the peeled workpiece to the top of the lamination component 7, realizing the automatic loading and film-tearing operation of the workpiece to be laminated. The specific model of the loading robot 61 is not limited, as long as it meets the usage requirements.

[0027] Furthermore, the material transfer component 65 includes a first KK module 651, a second KK module 652, and a second gripping suction cup 653. The first KK module 651 is fixedly connected to the top of the base 1, located on one side of the second linear motor 4 and the transfer table 64. The second KK module 652 is fixedly connected to the output end of the first KK module 651. The second gripping suction cup 653 is installed on the output end of the second KK module 652. Through the cooperation of the first KK module 651 and the second KK module 652, the second gripping suction cup 653 is driven to move, gripping and transferring the workpiece that has been peeled off by the transfer table 64, and accurately placing the workpiece on the designated station of the laminating component 7. In the specific implementation process, it is worth noting that through the cooperation between the first KK module 651, the second KK module 652, and the second gripping suction cup 653, by controlling the first KK module 651 and the second KK module 652, the second gripping suction cup 653 uses vacuum adsorption to adsorb and grip the material on the top of the transfer table 64 and transfer it to the lamination component 7. This achieves automatic and precise transfer of the workpiece to be laminated after the film is torn off, ensuring that the workpiece is placed accurately on the lamination component 7. The specific models of the first KK module 651 and the second KK module 652 are not limited, as long as they meet the usage requirements.

[0028] Furthermore, the lamination assembly 7 includes a negative pressure box 71, a grid plate 72, a pressure roller 73, and a roller pressing drive assembly 74. The negative pressure box 71 is fixedly connected to the output end of the second linear motor 4; the grid plate 72 is disposed on the top of the negative pressure box 71; the pressure roller 73 is disposed inside the negative pressure box 71; and the roller pressing drive assembly 74 is disposed inside the negative pressure box 71 at the bottom of the pressure roller 73. The negative pressure box 71 uses the grid plate 72 to perform negative pressure adsorption and fixation on the workpiece to be laminated, and the roller pressing drive assembly 74 drives the pressure roller 73 to reciprocate inside the negative pressure box 71, applying pressure from the lower surface of the workpiece to be laminated. In conjunction with the roller pressing drive assembly 74 above the workpiece, the multi-layer workpiece is uniformly rolled. In the specific implementation process, it is worth noting that after the workpiece to be laminated is placed on top of the grid plate 72, the negative pressure box 71 is activated to perform negative pressure adsorption. Through the evenly distributed ventilation holes on the grid plate 72, a uniform negative pressure suction is formed on the workpiece, which is stably adsorbed and fixed in the designated position. Driven by the second linear motor 4, the workpiece to be laminated is moved to the lamination station near the side of the first linear motor 2. After the upper workpiece is transferred by the first linear motor 2 and the material transfer suction cup 3 and placed on top of the lower workpiece to complete the alignment, the pressure roller 73, driven by the roller driving assembly 74, moves back and forth linearly at the bottom of the grid plate 72. With the covering and pressing cooperation of the material transfer suction cup 3, the multi-layer workpiece is evenly pressed from below, so that the air between the multi-layer workpiece is gradually discharged, ensuring that each layer of workpiece is tightly and evenly bonded.

[0029] Furthermore, the roller pressing drive assembly 74 includes a slide rail 741, a servo motor 742, a synchronous belt 743, a moving seat 744, a second servo cylinder 745, and a lifting seat 746. Two slide rails 741 are provided and fixedly connected to the inner sides of the negative pressure chamber 71. The servo motor 742 is mounted on the outer wall of the negative pressure chamber 71. The synchronous belt 743 is rotatably connected to the inside of the negative pressure chamber 71 and is drively connected to the output end of the servo motor 742. The moving seat 744 is slidably connected to the outer wall of the slide rail 741 and fixedly mounted. The second servo cylinder 745 is fixedly connected to the bottom two sides of the movable seat 744; the lifting seat 746 is located above the movable seat 744, fixedly connected to the output end of the second servo cylinder 745, and rotatably connected to the pressure roller 73; wherein, the second servo cylinder 745 drives the lifting seat 746 to rise and fall, while the servo motor 742 drives the synchronous belt 743 to rotate, driving the movable seat 744 to reciprocate, so that the pressure roller 73 applies pressure evenly to the lower surface of the workpiece to be laminated; In the specific implementation process, it is worth noting that during the lamination operation, the control system automatically controls the servo motor 742 and the second servo cylinder 745 to drive the lifting seat 746 to move upward, so that the pressure roller 73 contacts the grid plate 72 with a certain pressure. At the same time, the servo motor 742 drives the synchronous belt 743 to rotate, which drives the moving seat 744 to move back and forth along the slide rail 741, thereby driving the pressure roller 73 to perform reciprocating rolling at the bottom of the grid plate 72, gradually expelling the air remaining between the multiple layers of workpieces, and ensuring that each layer of the workpiece is tightly bonded.

[0030] Furthermore, the dust removal assembly 8 includes a particle counter 81, an ultrasonic dry cleaner 82, vertical rods 83, a plasma air nozzle 84, and a detection assembly 85. The particle counter 81 is fixedly connected to the outer wall of the base 1, and its output end is connected to the interior of the base 1. The ultrasonic dry cleaner 82 is fixedly connected to the top of the base 1, located above the second linear motor 4. Multiple vertical rods 83 are provided, fixedly connected to the top of the base 1, and spaced apart around the outer periphery of the pull-out plate 51. The plasma air nozzle 84 is fixedly connected to the top of the vertical rod 83. The detection assembly 85 is located above the second linear motor 4. The upper part of the machine 4 is located on the side of the ultrasonic dry cleaner 82 near the first linear motor 2; the particle counter 81 is located at the junction of the workpiece cleaning and inspection process and the lamination assembly process to perform real-time sampling and monitoring of air particle concentration. After the first gripping suction cup 62 adsorbs and grips the workpiece to be laminated, the plasma air nozzle 84 sprays out ionized airflow to eliminate static electricity on the workpiece surface. At the same time, when the workpiece passes through the ultrasonic dry cleaner 82 under the drive of the negative pressure box 71, the ultrasonic dry cleaner 82 performs dry cleaning on the workpiece surface to remove tiny particulate impurities attached to the workpiece surface. In the specific implementation process, it is worth noting that the particle counter 81 performs fixed-point air extraction detection at the junction of two processes, providing real-time feedback on the particle concentration data within the device. It can also be deployed at multiple points on different locations on the production line as needed to improve the comprehensiveness of particle concentration detection. When the detected particle concentration exceeds the preset threshold, the control system automatically increases the power of the exhaust system to accelerate the circulation speed of clean air inside the device, quickly reducing the particle concentration in the environment and preventing excess particles from adhering to the workpiece surface. After the first gripping suction cup 62 grips the workpiece and leaves the hopper, it passes through the plasma air nozzle 84 area during its movement. The plasma air nozzle 84 sprays an ionized gas flow to neutralize the static electricity on the workpiece surface, eliminating static... Tiny particles adhering to the surface of the workpiece after electrolysis are more easily blown away and cleaned. When the negative pressure box 71 moves the workpiece to below the ultrasonic dry cleaner 82, the ultrasonic dry cleaner 82 uses ultrasonic vibration combined with airflow to shake off and remove the tiny particle impurities adhering to the workpiece surface, thus achieving dry cleaning of the workpiece surface. After the dry cleaning operation is completed, the detection component 85 detects the particles remaining on the workpiece surface to confirm that the number of particles on the workpiece surface after cleaning meets the processing requirements. If the detection result does not meet the standard, the workpiece is returned to the cleaning process for cleaning again. The specific models of the particle counter 81, ultrasonic dry cleaner 82, and plasma air nozzle 84 are not limited, as long as they meet the usage requirements.

[0031] Furthermore, the detection component 85 includes a mounting bracket 851, a CCD camera 852, and a coaxial light source 853. The mounting bracket 851 is positioned above the second linear motor 4, located on the side of the ultrasonic dry cleaner 82 near the first linear motor 2. The CCD camera 852 is fixedly connected to both sides of the outer wall of the mounting bracket 851. The coaxial light source 853 is fixedly connected to the outer wall of the mounting bracket 851, located at the bottom of the CCD camera 852. After the workpiece to be laminated is cleaned by the ultrasonic dry cleaner 82, it moves to the area below the CCD camera 852. The two CCD cameras 852, in conjunction with the coaxial light source 853, perform imaging detection on the workpiece surface, identify and count residual particles on the workpiece surface, and determine whether the cleanliness of the workpiece surface meets the processing requirements. In the specific implementation process, it is worth noting that after the dry cleaning operation of the workpiece to be laminated is completed, the negative pressure box 71 moves the workpiece to the bottom of the fixed frame 851. The CCD camera 852 takes a picture of the workpiece surface, identifies and counts the tiny particle impurities remaining on the workpiece surface. When the number of residual particles exceeds the preset allowable range, the control system controls the second linear motor 4 to move the workpiece in the opposite direction, returning it to the bottom of the ultrasonic dry cleaner 82, and performs dry cleaning again until the detection result meets the standard before continuing to transport it to the lower lamination station. This prevents unqualified workpieces from flowing into the next process. The image data obtained by the CCD camera 852 generates the position information of the workpiece to be laminated, so that the material transfer suction cup 3 can adjust the position of the upper workpiece to ensure accurate alignment between the upper and lower workpieces. The specific models of the CCD camera 852 and the coaxial light source 853 are not limited, as long as they meet the usage requirements.
