Description

Technical Field

[0001] This invention relates to the field of electronic product packaging equipment technology, specifically to an electronic product packaging structure and method. Background Technology

[0002] With the popularization and iterative upgrades of consumer electronics products, their outer packaging not only needs to meet physical protection requirements such as dustproof, moisture-proof, and impact resistance, but also needs to have an aesthetically pleasing and neat visual presentation to meet the multiple needs of retail display and logistics transportation. Currently, various boxed electronic products often use heat-shrink film or heat-sealing film for external sealing to achieve sealing and shaping while displaying brand logos.

[0003] In actual packaging operations, traditional heat-sealing processes often rely on manual labor or semi-automatic equipment to complete film wrapping, heat sealing, and edge treatment. This method generally suffers from low packaging efficiency, poor edge consistency, and unsightly excess film at the edges. Especially when continuously packaging multi-specification products, it is difficult to quickly adjust and adapt, and the packaging quality is easily unstable due to fluctuations in manual operation. Furthermore, existing equipment often makes waste film recycling inconvenient, affecting the overall production cycle and material utilization rate. Summary of the Invention

[0030] According to another aspect of this disclosure, an electronic product packaging method is also provided, which encapsulates an electronic product using the electronic product packaging structure described above, including: Step 1: Material preparation and positioning / loading The heat-sealing film roll is installed on the pin 30, and the traction film head passes through the gap between the guide plate 24 and the placement plate 25 and is fixed to the recycling shaft 2. The boxed product is placed on the placement plate 25, so that one side of it is inserted into the box placement slot of the reset push plate 28. The first servo motor 9 is started, driving the reset push plate 28 to push the product forward along the conveyor belt 1. The product drags the film to achieve automatic film placement and covering.

[0031] Step Two: Three-sided heat sealing and waste disposal The product is guided by guide plate 24 and slides into the sealing base frame 19. The third cylinder 22 is activated to press the product against the clamping block 32. Then, the second cylinder 21 drives the side sealing plate 13 downwards, working with the resistance wire to complete the heat-pressing and sealing of the film on both sides, with excess film forming a "sealing corner." The fourth cylinder 31 drives the front sealing plate 23 to complete the heat sealing of the front film. After all cylinders reset, the fourth servo motor 3 drives the recovery shaft 2 to wind up the waste film. Finally, the first cylinder 20 lifts the sealing base frame 19 to release the product.

[0032] Step 3: Lifting and clamping, and trimming edges and corners Conveyor belt 1 transports the product to baffle 16 for positioning. Lifting cylinder 45 is activated to lift the product, while simultaneously, the clamping slider 12 automatically clamps the product via the linkage between the fixed sleeve 51 and the first connecting rod 53. Second servo motor 38 is activated to adjust the angle of trimming arm 17, aligning clamping block 39 with a "sealing corner." Trimming electric push rod 33 drives the clamping block to close, thermally cutting and sealing the corner via resistance wire. After the trimming arm removes and discards the scrap, third servo motor 50 drives the product to rotate 90°, sequentially completing the trimming of the remaining three corners.

[0033] Step 4: Reset and transfer output After the corner trimming is completed, the lifting cylinder 45 descends, the product is lowered, and the clamping slider 12 automatically releases. The moving electric push rod 34 pushes the reset plate 35 to push the product onto the surrounding short rollers 15. The short rollers rotate synchronously with the conveyor belt 1 via the auxiliary sprocket 56 and chain, sending the product back to the main conveyor belt and transporting it to the subsequent workstation.

[0034] Working principle: Material preparation and loading positioning: The operator places the entire roll of heat-sealing film onto the pin 30, pulls the film head through the guide gap between the guide plate 24 and the placement plate 25, and fixes its end to the winding surface of the recovery shaft 2. Then, the boxed electronic product to be packaged is placed on the placement plate 25, and one side is accurately inserted into the placement slot of the reset push plate 28. After positioning, the first servo motor 9 is started by the control system, driving the threaded rod 7 to rotate, which in turn drives the slider 5 to slide forward along the guide post 6, thereby pushing the reset push plate 28 and the product towards the inside of the conveyor belt. As the product moves forward, it drags the heat-sealing film forward synchronously, the film roll is passively released, and the film gradually covers the product surface.

[0035] Three-sided heat sealing and waste recycling: Guided by the guide plate 24, the product slides into the frame of the plastic sealing base frame 19 along its arc-shaped inner wall. At this point, the film has wrapped the three sides of the product except for the bottom. Then, the third cylinder 22 is activated, driving the pressing block 32 to press down, firmly pressing the product and film into the plastic sealing base frame 19. The first servo motor 9 reverses, driving the reset push plate 28 back to the initial standby position. Next, the second cylinder 21 is activated, driving the two side plastic sealing upper plates 13 to press down, making them tightly press against the side frames of the plastic sealing base frame 19. At the same time, the resistance wire embedded in the pressing surface is activated, melting and sealing the film on both sides at high temperature. The excess film edge forms a protruding "sealing corner" at the forming groove 11. Immediately afterwards, the fourth cylinder 31 is activated, driving the front plastic sealing upper plate 23 to press down, pressing against the front arc-shaped surface of the plastic sealing base frame 19, and completing the hot pressing and sealing of the front film through the resistance wire. After each heat-sealing cylinder rises and resets in sequence, the fourth servo motor 3 is started to drive the recovery shaft 2 to rotate, winding up the front end and the waste film edges that have been cut off, until the film in the working area returns to a flat state. Finally, the first cylinder 20 is started to lift the plastic sealing bottom frame 19, releasing the constraint on the product. At this point, the product has completed the pre-treatment of having an open bottom and heat-sealed on the other three sides.

[0036] Fine trimming and multi-faceted positioning of edges and corners: The conveyor belt 1 is started, transporting the product to the baffle 16 for longitudinal positioning. Four lifting cylinders 45 are activated, driving the cylinder lifting plate 48 and the cross-lifting frame 14 to rise, lifting the product away from the conveyor surface. During this process, the linkage mechanism formed by the fixed sleeve 51 and the first connecting rod 53 automatically drives the two clamping sliders 12 to move towards the center of the product, reliably clamping it from both sides. Subsequently, the second servo motor 38 is started, driving the trimming arm 17 and the trimming mounting plate 41 at the end to rotate through the meshing transmission of the drive gear 36 and the driven gear 37, so that the V-groove on the mounting plate is precisely aligned with a "sealing corner" of the product. The trimming electric push rod 33 is activated, driving two clamping blocks 39 embedded with resistance wires to slide and close along the inclined surface of the V-groove through the second connecting rod 55, clamping the "sealing corner." The resistance wires are energized to complete the hot-pressing cutting and sealing of the corner. After the trimming arm rotates and moves the cut corner to the outside of the equipment, the clamping blocks open to discard the material. Start the third servo motor 50, which drives the worm gear 54 via the worm 52, causing the cross-shaped support column 57 and the clamped product to rotate precisely 90 degrees. Repeat the above trimming and rotation process to clean the remaining three "sealing corners" in sequence.

[0037] Finished Product Unloading and Transfer Output: After all corner trimming is completed, the third servo motor 50 is controlled to rotate the product to a position where the baffle 16 faces away from the conveying direction. The lifting cylinder 45 descends, and the product descends with the cross-lifting frame 14. The clamping slider 12 is automatically released under the action of the linkage mechanism. The moving electric push rod 34 is activated, pushing the reset plate 35 to smoothly push the product from the cross-lifting frame 14 onto the short rollers 15 around it. The short rollers 15 rotate synchronously with the main conveyor belt 1 through the auxiliary sprocket 56 and auxiliary chain, thereby smoothly sending the product back to the main conveyor belt and conveying it to the subsequent heat shrink or collection station.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
