Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to a thermo-press packaging apparatus and method. Background Technology

[0002] In the field of electronic component manufacturing and processing, trays are often used to carry tape-and-roll components. After multiple trays are stacked, aluminum foil bags are usually used to vacuum seal the stacked trays to achieve moisture-proof, dust-proof and anti-static protection, and to prevent the components from failing due to environmental factors during storage and transportation.

[0003] In current packaging processes, multiple stacked trays are placed into an aluminum foil bag, and then the opening side of the bag is heat-sealed. However, the overall thickness of the package after stacking multiple trays is large. Due to the thickness of the stacked trays, the film on both sides of the bag opening is prone to misalignment, making it difficult to accurately align the packaging edges. At the same time, the film is easily wrinkled in the sealing area due to the pressure of the internal materials and the heat sealing. Wrinkles at the seal cause the heat-sealed surface to not adhere tightly, directly leading to a decrease in the sealing performance, resulting in problems such as air leakage and tearing. This causes the aluminum foil bag to lose its moisture-proof and anti-static protective effect, which in turn causes internal components to become damp and oxidized, suffer static damage, and increase the product scrap rate. Summary of the Invention

[0015] This invention also provides a hot-press packaging method, which uses the aforementioned hot-press packaging equipment to hot-press package aluminum foil bags containing multiple trays, comprising: Step S1, conveying the aluminum foil bags containing multiple trays to the working area of ​​the shaping mechanism via a transmission mechanism; Step S2, moving the pull tabs and suction nozzles in the shaping mechanism into the interior of the aluminum foil bag, driving the two pull tabs to move relatively away from each other in the horizontal direction to flatten the opening of the aluminum foil bag; Step S3, vacuuming the flattened aluminum foil bag using the suction nozzle, while simultaneously fixing the opening of the aluminum foil bag using the clamping component in the shaping mechanism until the vacuuming process is completed; Step S4, driving the upper heat-sealing beam and lower heat-sealing beam in the hot-pressing mechanism to move closer together, and pulling the suction nozzle out of the aluminum foil bag before they are sealed; Step S5, hot-pressing the opening of the aluminum foil bag using a heating element; Step S6, unloading the packaged product using the transmission component, resetting each structure to its initial position, and repeating the above steps for continuous cyclic processing.

[0016] The technical solution of the present invention has the following advantages compared with the prior art: The hot-press packaging equipment and method of this invention achieves orderly conveying of aluminum foil bags loaded with multiple stacked trays through a transmission mechanism. It works in conjunction with a negative pressure component, a flattening component, and a clamping component in the shaping mechanism. The suction nozzle of the negative pressure component extends into the aluminum foil bag. Combined with two sets of flattening components, the bags can be displaced along the length and width directions of the transmission component, respectively. A pull tab extends into the bag, and the clamping plate of the clamping component opens and closes the bag from the thickness direction. This allows for multi-directional stretching and shaping of the packaging edges of the aluminum foil bag, effectively correcting the bag misalignment problem caused by large-thickness stacked trays. The aluminum foil bags are pre-packaged... The heat-sealing area is flattened to eliminate wrinkles at the sealing edge. Then, the upper and lower heat-sealing components of the heat-pressing mechanism move vertically relative to each other, causing the upper and lower pressure strips to press against each other in conjunction with the heating element to complete the heat-press sealing of the aluminum foil bag edge. This ensures that the edges of the aluminum foil bag to be sealed are fully aligned and adhered, avoiding defects such as incomplete heat sealing, air leakage, and breaks caused by bag misalignment or wrinkles. This guarantees the sealing performance of the aluminum foil bag after sealing, and provides reliable moisture-proof and anti-static protection for the components on the internal stacked trays. It also reduces the probability of component scrap due to sealing failure and improves the yield of heat-press sealing of aluminum foil bags for thick materials.

[0017] The equipment can be adapted to the packaging of aluminum foil bags with large thickness after multiple trays are stacked. It automates the entire process of conveying, shaping and heat sealing, reduces manual intervention and improves the processing efficiency and product consistency of the packaging operation.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0022] Example 1: See Figures 1 to 8As shown, this embodiment provides a heat-sealing packaging device for heat-sealing aluminum foil bags 600 containing multiple trays 500. The device includes: a machine base 100; a transmission mechanism 200, which includes a transmission component 220 mounted on the machine base 100, along which the aluminum foil bags 600 containing multiple trays 500 move; and a shaping mechanism 300 mounted on the machine base 100 and located on one side of the transmission component 220, which includes a negative pressure component 340, two flattening components 330, and two clamping components. 350, the negative pressure component 340 is movable along the width direction of the transmission component 220, and includes a negative pressure connector 342 and a suction nozzle 343, wherein one end of the negative pressure connector 342 is connected to an external negative pressure generating device, and the other end is connected to the suction nozzle 343, and the suction nozzle 343 can be inserted into the aluminum foil bag 600; the two flattening components 330 are movable along the length and width directions of the transmission component 220 respectively, and each of the flattening components 330 includes a pull tab 334 that can be inserted into the aluminum foil bag 600; the two clamping components 350 are correspondingly connected to two Each of the flattening components 330 moves synchronously with the flattening component 330. Each of the clamping components 350 includes a clamping plate 355 that can open and close along the thickness direction of the aluminum foil bag 600. A hot pressing mechanism 400 includes an upper heat sealing component 420 and a lower heat sealing component 410 disposed on both sides of the shaping mechanism 300 along the height direction of the machine base 100. The upper heat sealing component 420 includes an upper heat sealing beam 424, a heating element 425, and an upper pressure strip 427. The heating element 425 is connected to one side of the upper heat sealing beam 424, and the upper pressure strip 427 is disposed on... The lower heat-sealing assembly 410 includes a lower heat-sealing beam 416, a support beam 415, and a lower pressure strip 417. The support beam 415 is disposed on one side of the lower heat-sealing beam 416, and the lower pressure strip 417 is disposed on the top surface of the lower heat-sealing beam 416. The upper heat-sealing beam 424 and the lower heat-sealing beam 416 can move relative to each other in the vertical direction. The upper pressure strip 427 and the lower pressure strip 417 can press against each other to seal the aluminum foil bag 600. The heating element 425 can press against the support beam to heat-press and seal the edge of the aluminum foil bag 600.

[0023] In this embodiment, the machine base 100 serves as the mounting base for the entire hot-pressing packaging equipment, providing mounting foundations and positioning support for the transmission mechanism 200, the shaping mechanism 300, and the hot-pressing mechanism 400. This ensures the assembly position accuracy of each mechanism, enabling each actuator to stably complete its corresponding action within a set stroke range, and guaranteeing the structural stability of the entire machine.

[0024] Furthermore, the machine tool 100 is equipped with a control mechanism. The transmission mechanism 200, the shaping mechanism 300, and the hot pressing mechanism 400 are all connected to the control mechanism. This allows the machine to uniformly receive position and status signals from each mechanism and output corresponding action control commands to the transmission mechanism 200, the shaping mechanism 300, and the hot pressing mechanism 400. This coordinates the feeding action of the transmission mechanism 200, the negative pressure adsorption, flattening and pulling, and clamping action of the shaping mechanism 300 and the vertical pressing and heating operation sequence of the hot pressing mechanism 400. This ensures orderly linkage and cooperation between the feeding, bag shaping, and hot pressing sealing processes, achieving fully automated control of the packaging process of aluminum foil bags 600 containing multiple material trays 500. It also ensures that the action sequence of each actuator is matched, avoids interference between the actions of each mechanism, and improves the stability of equipment operation and the consistency of packaging operations.

[0025] In this embodiment, the transmission component 220 of the transmission mechanism 200 is arranged on the machine base 100. It is mainly used to carry aluminum foil bags 600 containing multiple trays 500 and drive the aluminum foil bags 600 to move along the set path, so as to transport the aluminum foil bags 600 to be packaged to the corresponding work station of the shaping mechanism 300, complete the loading and transfer before packaging, realize the continuous feeding of workpieces, and provide workpiece conveying conditions for subsequent shaping and hot pressing processes.

[0026] Furthermore, the transmission assembly 220 includes a transmission frame 221, a support plate 222, a transmission belt 223, and a transmission driver 224. The transmission frame 221 is connected to the machine base 100, the transmission driver 224 is disposed on the transmission frame 221, the transmission belt 223 is disposed on the edge of the transmission frame 221 and connected to the power output end of the transmission driver 224, and aluminum foil bags 600 containing multiple trays 500 are supported on the transmission belt 223. The support plate 222 is disposed inside the transmission frame 221 and is disposed below the transmission surface of the transmission belt 223. The transfer frame 221 is used to assemble and fix with the machine 100, providing a mounting carrier for the support plate 222, the conveyor belt 223, and the transfer driver 224. The transfer driver 224 serves as a power source to provide operating power to the conveyor belt 223, driving the conveyor belt 223 to perform conveying motion. Aluminum foil bags 600 containing multiple trays 500 are supported on the conveyor belt 223, and the movement of the conveyor belt 223 is used to transfer the aluminum foil bags 600 to the shaping station. The support plate 222 is arranged inside the transfer frame 221. Furthermore, the conveyor surface, which is lower than that of the conveyor belt 223, can form internal support for the middle of the conveyor belt 223 when the aluminum foil bag 600 is moved to the working position of the shaping mechanism 300. This prevents the heavy aluminum foil bag 600 loaded with stacked trays 500 from bending the conveyor belt 223 and causing it to sink and deform, ensuring the positional accuracy of the aluminum foil bag 600 during the conveying process and preventing the aluminum foil bag 600 from shifting position due to the collapse of the conveyor belt 223. This provides a stable workpiece support foundation for the subsequent flattening and clamping operations of the aluminum foil bag 600 by the shaping mechanism 300.

[0027] Furthermore, the transmission mechanism 200 also includes a tray loading assembly 210, which is located at one end of the transmission assembly 220. The tray loading assembly 210 includes a loading rack 211, a loading belt 212, and a loading driver 213. The loading rack 211 is disposed on one side of the machine base 100, and the loading driver 213 is disposed on the loading rack 211. The loading belt 212 is connected to the power output end of the loading driver 213 to engage with the transmission assembly 220, and the tray 500 to be packaged is supported on the loading belt 212. The material tray loading assembly 210 serves as the front loading station of the equipment. Relying on the loading frame 211 fixed to one side of the machine base 100, it achieves stable assembly and positioning of the overall structure, providing reliable installation support for the loading driver 213 and the loading belt 212. The loading driver 213, as the core power component, drives the loading belt 212 to operate smoothly. The stacked material trays 500 to be packaged are stably supported on the loading belt 212. Automatic feeding of the material trays 500 is achieved through the conveying motion of the loading belt 212. Simultaneously, the end of the loading belt 212 connects with the transmission assembly... The precise docking of component 220 allows for the smooth transfer of the conveyed tray 500 to the conveying component 220, achieving seamless integration between the tray 500 loading process and the packaging and conveying process. This replaces manual loading, effectively improving the automation level and conveying efficiency of tray 500 loading, ensuring uniformity in the loading spacing and conveying speed of batch trays 500, and avoiding problems such as positional deviation and low efficiency associated with manual loading. This provides a continuous and regular supply of workpieces to ensure the continuous and stable operation of subsequent aluminum foil bag 600 packaging, shaping, and hot pressing processes.

[0028] The feeding rack 211 is equipped with two guide plates 214, which are respectively set on both sides of the feeding belt 212 to restrict the transmission direction of the tray 500. This effectively restricts the lateral deviation and deviation of the tray 500 during the conveying process, ensuring that the tray 500 always moves along the predetermined conveying direction of the feeding belt 212. This ensures that the tray 500 is in a regular conveying posture and can accurately connect to the transmission component 220 at the rear end. It also avoids the positional deviation of the tray 500 caused by the subsequent bagging, shaping and hot-pressing sealing processes, reduces the risk of poor sealing caused by workpiece misalignment, and ensures the positional accuracy and operational stability of the feeding and conveying process.

[0029] Specifically, the feeding rack 211 is equipped with a tray detector 215, which faces the feeding belt 212. This allows for real-time detection of whether there are trays 500 to be packaged on the feeding belt 212, obtaining detection signals of the presence or absence of trays 500 and their positioning status, and feeding these signals back to the control mechanism. This enables the identification of the workpiece status at the feeding station, facilitating the control mechanism to adjust the start / stop and conveying sequence of the tray feeding assembly 210 and the rear-end transmission mechanism 200 based on the detection signals. This avoids situations where there is no material and the trays 500 are conveyed empty or stacked and sent to the rear-end station, ensuring that the feeding process is orderly and controllable. It also prevents malfunctions in subsequent shaping and hot-pressing packaging processes caused by abnormal feeding, thereby improving the reliability of the entire machine operation.

[0030] In this embodiment, the support plate 222 has two clearance grooves 2221 arranged along its length at its center. The transmission mechanism 200 also includes a fixing component 230, which includes a connecting block 233, a fixing driver 231, a guide screw 232, and two clamping components 234. The connecting block 233 is connected to the support plate 222, the fixing driver 231 is disposed on the connecting block 233, and the guide screw 232 is connected to the power output end of the fixing driver 231. Each of the clamping components 234 includes a slider. 2341, a movable frame 2342, a lifting cylinder 2343, and a limiting clamping plate 2344. The slider 2341 is connected to the movable frame 2342 and sleeved and connected to the guide screw 232. The lifting cylinder 2343 is disposed on the movable frame 2342. The limiting clamping plate 2344 is connected to the power output end of the lifting cylinder 2343 for lifting and lowering movement. The limiting clamping plate 2344 can pass through the corresponding clearance groove 2221 to the top of the support plate 222 to laterally fix the aluminum foil bag 600 containing multiple trays 500. Two clearance slots 2221 provide passage space for the limiting clamping plate 2344, allowing it to extend upwards to the support plate 222 to perform clamping actions. The fixing assembly 230 achieves overall assembly positioning based on the connecting block 233 connected to the support plate 222. The fixed driver 231 outputs power to drive the guide screw 232 to rotate, thereby driving the sliders 2341 of the two sets of clamping components 234 to adjust their displacement towards or away from each other along the guide screw 232. The moving frame 2342 moves synchronously with the sliders 2341 to adjust the distance between the clamping components 234. The lifting cylinder 2343, mounted on the moving frame 2342, can drive the limiting clamping plate 2344 to perform lifting and lowering actions, thus limiting the clamping plate 2344. The clamping plate 2344 can extend through the corresponding clearance groove 2221 to the top of the support plate 222, and laterally clamp and fix the aluminum foil bag 600 containing multiple trays 500 on the conveyor belt 223. It can adapt to the positioning requirements of aluminum foil bags 600 with different widths. During the negative pressure adsorption, pull tab 334 insertion and flattening and pulling operations performed by the forming mechanism 300, the aluminum foil bag 600 is reliably limited, preventing the aluminum foil bag 600 from shifting or displacing as a whole under the pulling force. This ensures the positional stability of the aluminum foil bag 600 at the forming station, provides a reliable positioning basis for subsequent bag opening flattening and hot-pressing sealing operations, and reduces sealing defects caused by workpiece offset.

[0031] In this embodiment, the shaping mechanism 300 is arranged on one side of the transmission component 220 and is used to pre-process and shape the edge of the aluminum foil bag 600 to be sealed before heat sealing, eliminate bag misalignment and wrinkle defects, and provide a good bag condition for subsequent heat sealing operations.

[0032] The negative pressure component 340 can move along the width direction of the transmission component 220. The negative pressure connector 342 is used to connect to an external negative pressure generating device to realize the conduction and transmission of negative pressure air source. The suction nozzle 343 can extend into the aluminum foil bag 600 and rely on the negative pressure to adsorb and organize the bag body of the aluminum foil bag 600, assisting in opening the bag mouth of the aluminum foil bag 600 so that the subsequent pull tab 334 can be smoothly inserted into the bag. At the same time, it can cooperate with the displacement action to perform preliminary position correction of the bag body.

[0033] The two flattening components 330 can move along the length and width directions of the transmission component 220 respectively. The pull tabs 334 on the flattening components 330 can be inserted into the aluminum foil bag 600. By relying on the insertion of the pull tabs 334 and the displacement and pulling in the corresponding direction, the edges of the aluminum foil bag 600 to be sealed are pulled and flattened in multiple directions from the inside of the bag, which improves the problem of bag film offset and wrinkling caused by the large thickness of the internal stacked material tray 500.

[0034] The clamping component 350 is connected to the flattening component 330 and moves synchronously with the flattening component 330. The clamping plate 355 of the clamping component 350 can open and close along the thickness direction of the aluminum foil bag 600. When the clamping plate 355 is closed, it can clamp and fix the film of the aluminum foil bag 600, firmly clamp the film, and ensure that the film will not slip relative to the flattening component 330 during the stretching and flattening operation, maintain the alignment of the flattened bag, and prevent the film from being misaligned and wrinkled again during the shaping process.

[0035] Further, the shaping mechanism 300 includes a base plate 310 and a bidirectional moving module 320. The base plate 310 is disposed on the machine tool 100. The bidirectional moving module 320 includes a first horizontal track 321, a carriage 322, a second horizontal track 323, and a drive screw 326. The first horizontal track 321 is disposed on the base plate 310 and extends along the length direction of the transmission component 220. A first horizontal driver 324 is disposed on it. The carriage 322 is connected to the first horizontal driver 324 and slidably connected to the first horizontal track 321. The negative pressure component 340 is connected to the carriage 322. The second horizontal track 323 is disposed on the carriage 322 and extends along the width direction of the transmission component 220. A second horizontal driver 325 is disposed on it. The drive screw 326 is connected to the second horizontal driver 325. The flattening component 330 is connected to the drive screw 326. The substrate 310 provides an overall mounting carrier for the bidirectional moving module 320. A first horizontal track 321 extending along the length of the transmission component 220 in the bidirectional moving module 320 is equipped with a first horizontal driver 324, which drives the carriage 322 to move along the first horizontal track 321 in the length direction. The carriage 322 drives the negative pressure component 340 to move synchronously, thereby adjusting the position of the negative pressure component 340 along the length of the transmission component 220. A second horizontal track 323, mounted on the carriage 322 and extending along the width of the transmission component 220, is equipped with a second horizontal driver 325, which drives the drive screw 326 to move. The driving flattening component 330 achieves position adjustment along the width direction of the transmission component 220. Through the cooperation of the first horizontal rail 321 and the second horizontal rail 323, the negative pressure component 340 and the flattening component 330 can be flexibly moved in two orthogonal directions of the length and width of the transmission component 220, respectively. This can adapt to the bag opening position of aluminum foil bags 600 of different specifications, ensuring that the suction nozzle 343 of the negative pressure component 340 and the pull tab 334 of the flattening component 330 can accurately extend into the interior of the aluminum foil bag 600. This provides a reliable motion basis for the negative pressure opening and multi-directional flattening and shaping action of the aluminum foil bag 600 sealing edge, and improves the adaptability and action accuracy of the shaping mechanism 300.

[0036] Correspondingly, the flattening assembly 330 includes a stretching slide 331, a sliding sleeve 332, and an extension rod 333. The sliding sleeve 332 is disposed on the stretching slide 331 and sleeved and connected to the drive screw 326. One end of the extension rod 333 is connected to the stretching slide 331, and the other end extends toward the transmission assembly 220 and is connected to the pull tab 334. The stretching slide 331 of the flattening assembly 330 is sleeved with the drive screw 326 through the sliding sleeve 332 disposed thereon. Under the driving action of the drive screw 326, the stretching slide 331 is smoothly slid, thereby completing the displacement adjustment of the flattening assembly 330. One end of the extension rod 333 is connected to the stretching slide 331, and the other end extends toward the transmission assembly 220 and is fitted with the pull tab 334. With the bridging arrangement of the extension rod 333, the pull tab 334 is conveyed to the bag opening position of the aluminum foil bag 600, ensuring that the pull tab 334 can smoothly extend into the aluminum foil. Inside the bag 600, the linear driving force output by the drive screw 326 is effectively transmitted to the pull tab 334, enabling the pull tab 334 to obtain sufficient pulling stroke and pulling force, thereby performing a pulling and flattening operation on the sealing edge of the aluminum foil bag 600. At the same time, the cooperation between the sliding sleeve 332 and the drive screw 326 can ensure the guiding accuracy of the stretching slide 331 during its movement, reduce the shaking deviation during the movement, and ensure the stability of the pull tab 334 during its displacement process, providing reliable structural support for the shaping and flattening of the edge of the aluminum foil bag 600 to be sealed.

[0037] Similarly, the negative pressure assembly 340 includes a negative pressure connecting frame 341, which is connected to the slide 322 to realize the assembly connection between the negative pressure assembly 340 and the slide 322. The negative pressure assembly 340 is fixedly installed on the slide 322, so that the negative pressure assembly 340 can move synchronously with the slide 322. This drives the negative pressure connector 342 and the suction nozzle 343 to adjust their positions synchronously, ensuring that the suction nozzle 343 can accurately align with the opening of the aluminum foil bag 600 with the movement of the bidirectional moving module 320. This provides stable installation support for the negative pressure assembly 340 as a whole, reduces the risk of shaking and displacement of the negative pressure assembly 340 during the moving operation, ensures the stability and positional accuracy of the suction nozzle 343's alignment action, and provides a reliable structural foundation for the subsequent insertion of the suction nozzle 343 into the aluminum foil bag 600 to carry out negative pressure opening operations.

[0038] In this embodiment, the clamping assembly 350 includes a clamping connecting frame 351, a first adjustment driver 352, a second adjustment driver 353, and an opening / closing driver 354. The clamping connecting frame 351 is connected to the tension slide 331. The first adjustment driver 352 is disposed on the clamping connecting frame 351 and can move along the length direction of the transmission assembly 220. The second adjustment driver 353 is disposed on the first adjustment driver 352 and can move along the width direction of the transmission assembly 220. The opening / closing driver 354 is disposed on the second adjustment driver 353, and its power output end is connected to the two clamping plates 355. The clamping assembly 350 and the flattening assembly 330 are fixedly connected by the clamping connecting bracket 351 and the tension slide 331, enabling the clamping assembly 350 to synchronously complete the basic displacement with the tension slide 331. The first adjustment driver 352 and the second adjustment driver 353 are assembled in sequence, which can respectively realize the fine adjustment of the position along the length and width directions of the transmission assembly 220, and drive the opening and closing driver 354 and the clamping plate 355 to perform position compensation. The opening and closing driver 354 is installed on the second adjustment driver 353 and is used to drive the two clamping plates 355 to perform the position compensation. The opening and closing action allows the clamping plate 355 to not only follow the flattening assembly 330 to complete a large stroke movement, but also to achieve fine adjustment of the position of the clamping plate 355 with the help of the two-stage driver, adapting to the actual position of the sealing edge of the aluminum foil bag 600. This ensures that the clamping plate 355 can be accurately aligned with the film of the aluminum foil bag 600 and reliably clamped, avoiding misalignment and separation between the clamping plate 355 and the film during the flattening and pulling process. This ensures the clamping effect on the film of the aluminum foil bag 600, maintains the flattened and aligned state of the sealing edge of the bag after flattening and shaping, and provides good pre-treatment conditions for the subsequent hot pressing process.

[0039] In this embodiment, the hot-pressing mechanism 400 is located at the workstation of the shaping mechanism 300 and is used to perform hot-press sealing operations on the edges of the shaped aluminum foil bag 600. The upper heat-sealing assembly 420 and the lower heat-sealing assembly 410 are respectively arranged on both sides of the shaping mechanism 300 along the height direction of the machine base 100. The upper heat-sealing beam 424 serves as the supporting base of the upper heat-sealing assembly 420 and is used to install and fix the heating element 425 and the upper pressure strip 427. The heating element 425 provides the heat source required for heat sealing. During the hot-pressing operation, it can press against the support beam to heat the edges of the aluminum foil bag 600 sandwiched between the two, so that the material at the sealing edge of the aluminum foil bag 600 is heated and melted. The upper pressure strip 427 is installed on the bottom surface of the upper heat-sealing beam 424 and is used to provide the extrusion pressure during heat sealing. The lower heat-sealing beam 416 serves as the supporting base of the lower heat-sealing assembly 410, used to assemble the support beam and the lower pressure strip 417. The support beam cooperates with the heating element 425 to bear the heat-pressing force, providing a pressure carrier for sealing the aluminum foil bag 600. The lower pressure strip 417 is arranged on the top surface of the lower heat-sealing beam 416 and cooperates with the upper pressure strip 427 to form an extrusion pair. The upper heat-sealing beam 424 and the lower heat-sealing beam 416 can move relative to each other in the vertical direction, driving the upper pressure strip 427 and the lower pressure strip 417 to press against each other, pressing the edge of the aluminum foil bag 600 after shaping and flattening. Combined with the heating effect of the heating element 425, the sealing position of the aluminum foil bag 600 is heated and pressed to complete the heat-pressing sealing, realizing the sealing operation of the aluminum foil bag 600 containing the stacked material tray 500.

[0040] Furthermore, the upper heat sealing assembly 420 includes a gantry frame 421, a lower pressure driver 422, a lower pressure frame 423, and a guide column 426. The gantry frame 421 is supported on the machine base 100. The lower pressure driver 422 is connected to the top beam of the gantry frame 421. The lower pressure frame 423 is connected to the power output end of the lower pressure driver 422. The upper heat sealing beam 424 is connected to the lower pressure frame 423. The guide column 426 extends vertically, with one end connected to the lower pressure frame 423 and the other end slidingly passing through the top beam of the gantry frame 421. The gantry frame 421 provides a mounting base and load-bearing support for the lower pressure actuator 422 and the guide column 426. The lower pressure actuator 422 is mounted on the top beam of the gantry frame 421 and outputs vertical driving force to drive the lower pressure frame 423 and the upper heat sealing beam 424 mounted on the lower pressure frame 423 to achieve the overall lifting and lowering movement, thereby realizing the pressing and lifting action of the upper heat sealing assembly 420. The guide column 426, which is arranged vertically, is connected to the lower pressure frame 423 at one end and slides through the top beam of the gantry frame 421 at the other end. During the lifting and lowering process of the lower pressure frame 423 driven by the lower pressure driver 422, it plays a guiding and limiting role, constraining the lower pressure frame 423 to only move in the vertical direction, effectively offsetting the lateral component force generated during the pressing process, preventing the lower pressure frame 423 and the upper heat sealing beam 424 from tilting or swaying, ensuring the coaxiality of the lifting and lowering movement of the upper heat sealing beam 424 and the accuracy of the pressing position, so that the upper pressure strip 427 can be pressed smoothly and evenly at the sealing edge position of the aluminum foil bag 600, ensuring uniform pressure distribution during heat sealing, and improving the sealing effect and operational stability of heat sealing.

[0041] The lower heat-sealing assembly 410 includes a mounting vertical plate 411, a lifting driver 413, and a lifting slide plate 414. The mounting vertical plate 411 is arranged vertically and has a lifting track 412 extending in the same direction. The lifting driver 413 is arranged on the mounting vertical plate 411, and its power output end is connected to the lifting slide plate 414 to drive the lifting slide plate 414 to slide and connect to the lifting track 412. The support beam 415 is arranged on the mounting vertical plate 411 and is located at the top of the lifting track 412. The lower heat-sealing beam 416 is connected to the lifting slide plate 414. The mounting plate 411 provides a mounting carrier for the lifting drive 413, the lifting rail 412, and the support beam 415. The lifting rail 412 provides vertical movement guidance for the lifting slide plate 414. The lifting drive 413 outputs driving force to drive the lifting slide plate 414 to slide up and down along the lifting rail 412, thereby driving the lower heat-sealing beam 416 mounted on the lifting slide plate 414 to achieve vertical displacement adjustment. The support beam 415 is set on the mounting plate 411 and is located at the top of the lifting rail 412, which can adjust the vertical displacement of the slide plate 414. The sliding plate 414 serves as a travel limiter and pressure protector, thereby enabling the relative pressing action between the lower heat sealing beam 416 and the upper heat sealing beam 424. The lifting track 412 can constrain the movement trajectory of the lifting plate 414, reduce the swaying and deviation of the lower heat sealing beam 416 during the lifting process, ensure the straightness of the lifting movement of the lower heat sealing beam 416, and enable the lower pressure strip 417 to achieve precise alignment and pressing with the upper pressure strip 427. This ensures uniform pressure at the sealing edge of the aluminum foil bag 600, and improves the pressing accuracy and sealing reliability of the hot-press packaging.

[0042] In this embodiment, the hot pressing mechanism 400 further includes an auxiliary component 430. The auxiliary component 430 includes a suction cylinder 432, a connecting plate 433, and at least two auxiliary suction cups 431. The suction cylinder 432 is mounted on the top beam of the gantry frame 421. The connecting plate 433 is located at the power output end of the suction cylinder 432. At least two auxiliary suction cups 431 are arranged on the connecting plate 433 and can adhere to the aluminum foil bag 600 to be heat-sealed. The suction cylinder 432 is mounted on the top beam of the gantry frame 421 and can drive the connecting plate 433 to achieve reciprocating motion in the vertical direction. The connecting plate 433 is used to arrange and install at least two auxiliary suction cups 431. The downward movement of the connecting plate 433 driven by 432 allows the auxiliary suction cup 431 to adhere to the aluminum foil bag 600 to be heat-sealed. The suction force generated by the auxiliary suction cup 431 pre-adsorbs and fixes the area of ​​the aluminum foil bag 600 to be heat-sealed. Before the heat pressing is performed, the sealing edge of the aluminum foil bag 600 is further positioned and constrained. This can cooperate with the shaping effect of the shaping mechanism 300 to suppress warping, springback and displacement of the sealing edge of the aluminum foil bag 600, prevent the bag film from shifting during the heat pressing process, and ensure that the edge of the aluminum foil bag 600 to be heat-sealed is always in a flat state. This provides a stable workpiece posture for the pressing and heat sealing of the upper and lower heat sealing components, further reduces the risk of heat sealing wrinkles and misalignment, and improves the finished product quality of the aluminum foil bag 600 heat-sealed package.

[0043] Example 2: This example provides a hot-press packaging method, which uses the hot-press packaging equipment described in Example 1 to hot-press package an aluminum foil bag 600 containing multiple trays 500. The method includes: Step S1: The aluminum foil bag 600 containing multiple trays 500 is transferred to the working area of ​​the shaping mechanism 300 through the transfer mechanism 200, thereby realizing the station transfer of the workpiece to be processed and accurately delivering the aluminum foil bag 600 to the designated position of the shaping operation. This provides the workpiece position basis for the subsequent pulling sheet 334 and suction nozzle 343 to enter the bag to perform shaping and vacuuming processes, ensuring that subsequent processes can be aligned with the opening of the aluminum foil bag 600.

[0044] Step S2: Move the pull tab 334 and suction nozzle 343 in the shaping mechanism 300 into the aluminum foil bag 600, and drive the two pull tabs 334 to move away from each other in the horizontal direction to flatten the opening of the aluminum foil bag 600. This allows the opening to be pulled from inside the aluminum foil bag 600, and the misalignment and wrinkles of the bag film caused by the stacked material tray 500 to be initially flattened and corrected, eliminating the local warping and offset at the opening of the aluminum foil bag 600, and creating a flat bag opening condition for subsequent vacuuming operations.

[0045] Step S3: Vacuum the flattened aluminum foil bag 600 using the suction nozzle 343. Simultaneously, fix the opening of the aluminum foil bag 600 using the clamping component 350 in the shaping mechanism 300 until the vacuuming process is complete. This process removes air from the bag, allowing it to fit snugly against the internal tray 500. The clamping component 350 also fixes the opening of the aluminum foil bag 600 to prevent the bag opening from shrinking or misaligning during the vacuuming process, ensuring the stability of the bag opening shape. This process continues until the vacuuming process is complete, ensuring the vacuum level inside the aluminum foil bag 600.

[0046] In step S4, the upper heat-sealing beam 424 and the lower heat-sealing beam 416 in the driving hot-pressing mechanism 400 are brought closer together. Before they are bonded together, the suction nozzle 343 is pulled out of the aluminum foil bag 600. This prepares the suction nozzle 343 for hot-pressing and sealing, and also prevents the suction nozzle 343 from being squeezed and damaged by the upper and lower heat-sealing beams. At the same time, it prevents the suction nozzle 343 from being stuck in the bag, causing the aluminum foil bag 600 to be jammed and the seal to fail, thus ensuring that the subsequent heat-sealing operation can be carried out normally.

[0047] Step S5: The opening of the aluminum foil bag 600 is heat-pressed and sealed by the heating element 425, thereby melting and pressing the sealing material of the aluminum foil bag 600 to complete the sealing operation of the opening of the aluminum foil bag 600, realizing the vacuum sealing of the stacked tray 500, and ensuring the sealing and protection performance after sealing.

[0048] Step S6: The packaged product is unloaded through the transmission component 220. After each structure is reset to its initial position, the above steps are repeated for continuous cyclic processing.

[0049] In summary, the hot-press packaging equipment and method of the present invention achieves orderly conveying of aluminum foil bags 600 loaded with multi-stacked trays 500 through the transmission mechanism 200. It works in conjunction with the negative pressure component 340, flattening component 330, and clamping component 350 in the shaping mechanism 300. The suction nozzle 343 of the negative pressure component 340 extends into the aluminum foil bag 600. Combined with the two sets of flattening components 330, they can be displaced along the length and width directions of the transmission component 220, respectively. The pull tab 334 extends into the bag, and the clamping plate 355 of the clamping component 350 opens and closes the aluminum foil bag 600 from the thickness direction. This allows for multi-directional stretching and shaping of the packaging edges of the aluminum foil bag 600, effectively correcting the bag misalignment caused by the large-thickness stacked trays 500. To address the issue of positioning, the aluminum foil bag 600 is pre-flattened at the heat-sealing edge to eliminate wrinkles. Then, the upper heat-sealing component 420 and the lower heat-sealing component 410 of the heat-pressing mechanism 400 move vertically relative to each other, causing the upper pressure strip 427 and the lower pressure strip 417 to press against each other in conjunction with the heating element 425 to complete the heat-press sealing of the aluminum foil bag 600 edges. This ensures that the edges of the aluminum foil bag 600 to be sealed are fully aligned and fitted, avoiding defects such as incomplete heat sealing, air leakage, and breaks caused by bag misalignment or wrinkles. This guarantees the sealing performance of the aluminum foil bag 600 after sealing, thereby providing reliable moisture-proof and anti-static protection for the components on the internal stacked tray 500, reducing the probability of component scrap due to sealing failure, and improving the yield of heat-press sealing of aluminum foil bags 600 for thick materials.

[0050] The entire equipment can be adapted to the packaging of aluminum foil bags with a large thickness after stacking multiple trays of 500. It automates the entire process of conveying, shaping and heat sealing, reduces manual intervention and improves the processing efficiency and product consistency of the packaging operation.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
