Description

Technical Field

[0001] The present invention belongs to the field of mechanical technology and relates to a fully automatic packaging device, in particular to a packaging film laminating production line and a packaging method thereof. Background Art

[0002] With the advancement of society and technology, smart electronic products have become indispensable tools in human society. The demand for modern, fully automated production of smart electronic products is also increasing to meet consumer demand. Small electronic products require packaging and film lamination to be shipped as finished products. Traditional packaging and film lamination processes rely on manual labor, resulting in high processing costs, low efficiency, large film lamination errors, and poor film fastness.

[0003] To solve the above technical problems, for example, a Chinese patent document has disclosed a flexible film packaging production line [Chinese Patent No.: 202023179229.6], which discloses a flexible film packaging production line. The top surface of the support plate is inherently provided with a transverse positioning block, a longitudinal positioning block and a positioning cylinder located on the right side of the conveying channel. The transverse positioning block is arranged behind the rear guide bar, and an L-plate is fixed on the active end of the positioning cylinder piston rod. The transverse plate of the L-plate is arranged opposite to the transverse positioning block in front and back, and the transverse plate is flush with the inner side surface of the front guide bar. The longitudinal plate of the L-plate is arranged between the guide bar and the positioning cylinder. A push cylinder is fixed on the top surface of the rear guide bar, and a push plate is fixed on the active end of the push cylinder piston rod. The beneficial effects of this patent are: compact structure, improved product production efficiency, reduced film laminating cost, improved film laminating quality, and high degree of automation.

[0004] The above technical solution uses a vibrating plate for automatic feeding, a flat belt conveyor for product transport, and a four-axis robot for film application. This means that the above technical solution applies film to each product individually, which places high demands on visual positioning before film application. This not only increases the number of visual capture and processing equipment, but also affects film application efficiency. Furthermore, if strip film is used for strip application, strict control of product spacing is required. The above technical solution lacks the structure and function to adjust and position product spacing. Therefore, to improve film application efficiency, the above technical solution still needs further improvement. Summary of the Invention

[0017] A packaging method for a packaging film laminating line comprises the following steps:

[0018] 1) Start the lifter to drive the stacking rack and the tray to rise. When the sensor senses that the tray plate has risen to the right position, the lifter stops. At this time, the limit rod extends into the inlet and outlet of the tray insertion station, blocking the tray in the tray insertion station. The limit cylinder pulls out the limit rod to make the inlet and outlet of the corresponding tray insertion station unobstructed.

[0019] 2) Start the tray pulling motor to drive the tray pulling frame forward through the transmission belt assembly to connect the tray in the tray stacking frame, start the vertical cylinder to drive the hook upward to hook the bottom edge of the tray, start the tray pulling motor to drive the tray pulling frame through the transmission belt assembly to pull the tray backward, pull the tray out of the tray stacking frame and slide it onto the guide slide;

[0020] 3) Start the transverse motor to drive several suction nozzles to move transversely to the top of the material tray, start the lifting cylinder to drive several suction nozzles to descend and absorb some materials, the lifting cylinder drives several suction nozzles to rise, start the transverse motor to drive several suction nozzles to move transversely to the top of the insert plate;

[0021] Start the variable pitch cylinder to pull the last slider and the suction nozzle to move. When the relative telescopic displacement between the last clip and the limit slot reaches the limit, the clip engages and drives the second last slider and the suction nozzle to move. Thus, the transmission is carried out one by one until the suction nozzles as a whole are at the maximum distance. Start the lifting cylinder to drive the suction nozzles to descend and put the materials into the cavity of the insert plate one by one.

[0022] 4) Start the clamping cylinder to push the transmission plate, drive the X clamping rod to slide along the X groove and clamp the X side of the product in the cavity; synchronously drive the Y clamping block to slide along the Y groove and clamp the Y side of the product in the cavity;

[0023] When the X clamping rod moves into position along the X direction, its positioning notch is connected with positioning hole 1 and positioning hole 2; the locking cylinder is started to lift the locking rod so that the locking rod passes through positioning hole 1, positioning notch and positioning hole 2 to form a clamping position;

[0024] 5) The material box tape is pulled out from the material box reel, and the material box tape extends through the guide rod and enters the conveying track of the material box conveying device. The conveying motor is started to drive the drive disk to rotate in a directional manner, so that the driving protrusions are continuously embedded in the driving holes of the material box tape and move forward one by one, realizing the directional transportation of the material box tape;

[0025] 6) Start the second transverse motor to drive several suction nozzles to move horizontally to the top of the inserting plate of the secondary positioning device, start the second lifting cylinder to drive several suction nozzles to descend and suck the material, the second lifting cylinder drives several suction nozzles to rise, start the second transverse motor to drive several suction nozzles to move horizontally to the top of the material box belt, start the second lifting cylinder to drive several suction nozzles to descend and put the materials into the box cavity of the material box belt one by one;

[0026] 7) Pull the film tape out from the film tape reel, extend it outward through the guide rod 2 and into the bottom of the guide wheel, and then pass under the swing shaft to contact the surface of the material box tape, so that the film tape and the material box tape are transferred synchronously and passed through the bottom side of the film pressing wheel for bonding and pressing;

[0027] 8) Start the reel motor to drive the reel to rotate. The box tape that has completed the film lamination passes through the guide rod 3 and the guide rod 4 in sequence to change the conveying direction, and finally enters the reel to be reeled.

[0028] Compared with the existing technology, this packaging film laminating production line and its packaging method have the following beneficial effects:

[0029] 1. Through the rational layout of the loading bin, tray transfer device, variable-distance material transfer device, secondary positioning device, material box reel, material box conveying device, material transfer and box loading device, film tape reel, film laminating device and material receiving device, a Y-shaped processing line is realized where the product supply line and the material box supply line intersect the loading and laminating line, thereby rationally utilizing the production space, occupying less area, and reducing the product transportation path. The overall structure is compact and highly integrated, which is conducive to optimizing the production process, improving efficiency and increasing output.

[0030] 2. Through the close cooperation of stacking tray loading and pulling tray transfer, the accurate movement of the tray is ensured while saving space, and the precise placement of materials in the tray is further guaranteed, thereby avoiding the vacuum phenomenon caused by misplacement of material, which ultimately causes the problem of empty packaging, and effectively ensuring the effectiveness of packaging.

[0031] 3. By coordinating variable-distance suction with secondary positioning, different spacing adjustments can be handled while ensuring accuracy after the distance change. Secondary positioning uses a single driver to synchronize two-way clamping, which not only reduces the number of driver settings and reduces costs, but also reduces fixing errors through synchronous clamping action, improving clamping efficiency. In addition, a clamping balance is formed in the two-way linkage, avoiding product damage caused by a single clamping tooth being too tight, or positioning errors caused by a single clamping tooth being too loose. The two-way linkage clamping further improves positioning accuracy.

[0032] 4. The tooth-tooth mechanism achieves directional conveying of the box belt, which helps control the conveying rhythm to coordinate with batch loading, effectively avoid the risk of empty boxes, and improve packaging yield. The use of strip conveying film laminating method simplifies the film laminating device, improves film laminating efficiency, and ensures film laminating accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The stacked tray frame 3 and the bin frame 1 are vertically guided and slidably connected through vertical rails and vertical blocks. A plurality of sensors are fixed on the frame of the bin frame 1 at the feeding cavity, and are used for sensing the lifting position of the stacked tray frame 3. The stacked tray frame 3 is lifted in the feeding cavity through the lifter 2, and any tray plate 4 is sensed to be lifted to a precise position through the sensors. The limiting rod 5 is inserted into the inlet and outlet of the disc inserting station, and forms a blocking effect on the disc in the disc inserting station. The notches of the plurality of limiting rods 5 are vertically connected, and the connecting disc 7 is moved up and down relative to the plurality of notches in the process of lifting the stacked tray frame 3.

The limiting cylinder 6 retracts the telescopic shaft to synchronously pull out the limiting rod 5, and the inlet and outlet of the corresponding disc inserting station are unblocked, so that the disc pulling operation is realized. After the disc is pulled out, the limiting cylinder 6 drives the limiting rod 5 to reset.

[0047] As shown in the drawings, Figure 3 and Figure 4 The disc moving device includes a support with a guide slide 8, a reciprocating driving mechanism is arranged below the guide slide 8, the reciprocating driving mechanism includes a disc pulling motor 9 drivingly connected to a transmission belt assembly, the transmission belt assembly synchronously drives a disc pulling frame 14, a fulcrum seat is arranged on the disc pulling frame 14, a lever 15 is hinged to the fulcrum seat, one end of the lever 15 is swingingly driven by a vertical cylinder 16, and the other end of the lever 15 is swingingly connected to a pulling hook 17.

[0048] The transmission belt assembly includes a driving wheel 10 fixedly sleeved to the rotating shaft of the disc pulling motor 9, and a driven wheel 11 hinged to the support, the driving wheel 10 and the driven wheel 11 are externally peripherally tensioned with a belt 12, and the belt 12 is fixedly connected to the disc pulling frame 14 through a connecting block 13.

[0049] A photoelectric switch 18 is mounted above the front end of the guide slide 8 to sense whether the material tray is pulled out and whether the material tray is accurately in place.

[0050] like Figure 4 As shown, the variable-pitch material moving device includes a truss, a transverse motor 19 mounted on the truss. The transverse block of transverse motor 19 is connected to a lifting cylinder 20. The telescopic end of lifting cylinder 20 is connected to a retrieving rack 21. Several suction nozzles 22 are arranged in a sliding manner on retrieving rack 21 and are driven and connected by a variable-pitch assembly. Transverse motor 19 drives the suction nozzles 22 to reciprocate between the shifting device and the secondary positioning device. Lifting cylinder 20 drives the suction nozzles 22 to move up and down, thus achieving the material picking and unloading action.

[0051] like Figure 5 As shown, the pitch-changing assembly includes a pitch-changing cylinder 25 fixedly mounted on a material-retrieving rack 21, a slider 23 fixedly sleeved on the outer periphery of each suction nozzle 22, a groove is recessed on the material-retrieving rack 21, and several sliders 23 are embedded in the groove. The first slider 23 is fixed in the groove, and the remaining sliders 23 form a guide connection with the groove. A limit groove is recessed on the back side of the slider 23, and a buckle 24 is connected between adjacent limit grooves. A relative telescopic displacement is left between the buckle 24 and the limit groove, and the push-pull rod of the pitch-changing cylinder 25 is fixedly connected to the last slider 23.

[0052] The variable pitch cylinder 25 is activated to retract the push-pull rod, synchronously pulling the last slider 23 and the suction nozzle 1 22 to move. At this time, the other sliders 23 do not move. When the relative telescopic displacement between the last clip 24 and the limit slot reaches the limit, the clip 24 engages and drives the next last slider 23 and the suction nozzle 1 22 to move, thereby transmitting one by one until the entire number of suction nozzles 1 22 are spread out to the maximum spacing, achieving the operation of increasing the spacing. The variable pitch cylinder 25 is activated to extend the push-pull rod, synchronously pushing the last slider 23 and the suction nozzle 1 22 to move, so that the clip 24 and the limit slot are disengaged until the sliders 23 are successively aligned, so that the entire number of suction nozzles 1 22 are brought together to the minimum spacing, achieving the operation of decreasing the spacing.

[0053] like Figure 6 and Figure 7 As shown, the secondary positioning device includes a carrier 26 with an inserting plate 27, and a plurality of cavities 27a are arranged in the inserting plate 27, and a plurality of cavities 27a are opened on the same side of the carrier 26; a transmission plate 28 is slidably connected to the top surface of the carrier 26, and the transmission plate 28 is driven and connected by a clamping cylinder 29, and a plurality of inclined grooves 28a are arranged on the transmission plate 28, and the plurality of inclined grooves 28a are arranged in a one-to-one correspondence with the plurality of cavities 27a, and a guide column is inserted into the inclined groove 28a to form a sliding connection, and the guide column is fixedly connected to the X clamping rod 30, and the X clamping rod 30 forms an X-guide sliding connection with the carrier 26, and the clamping head of the X clamping rod 30 extends into the cavity 27a through the clamping notch.

[0054] The top surface of the carrier 26 is recessed with a guide groove, into which a drive plate 28 engages, forming a reciprocating sliding connection. The drive plate 28 is arranged parallel to the insert plate 27, and a clamping cylinder 29 is fixed to the side of the carrier 26. A recessed X-shaped groove is also formed on the top surface of the carrier 26, into which an X-shaped clamping rod 30 engages, forming an X-shaped guide sliding connection. Activating the clamping cylinder 29 pushes the drive plate 28. The X-shaped groove constrains the X-shaped clamping rod 30 in the Y direction, forcing the guide post to slide along the inclined groove 28a. The X-shaped clamping rod 30 then slides along the X-shaped groove and clamps the X-edge of the product within the cavity 27a.

[0055] like Figure 7 As shown, the X-clamping rod 30 defines a curved groove 30a. A guide pin is inserted into the groove 30a, forming a sliding connection. The guide pin is fixed to the Y-clamping block 31. The Y-clamping block 31 forms a Y-guided sliding connection with the insert plate 27. The clip of the Y-clamping block 31 extends from the bottom side into the cavity 27a. The insert plate 27 defines a Y-groove, into which the Y-clamping block 31 fits, forming a Y-guided sliding connection. Activating the clamping cylinder 29 pushes the transmission plate 28, causing the X-clamping rod 30 to slide along the X-groove. The Y-groove constrains the Y-clamping block 31 in the X direction, driving the guide pin along the curved groove 30a. The Y-clamping block 31 then slides along the Y-groove and clamps the Y side of the product within the cavity 27a.

[0056] A locking cylinder 32 is installed on the carrier 26, and the locking cylinder 32 drives the locking plate 33 to move up and down. A number of locking rods 34 are erected on the locking plate 33. A number of positioning holes 1 are correspondingly opened on the carrier 26, and a number of positioning recesses are correspondingly opened on the X clamping rods 30. A number of positioning holes 2 are correspondingly opened on the inserting plate 27. The locking rods 34 pass through the positioning hole 1, the positioning recess and the positioning hole 2 in sequence from bottom to top.

[0057] The clamping cylinder 29 is activated to push the transmission plate 28, utilizing the bidirectional constraint of the guide track to simultaneously clamp the product in the X and Y directions. When the X clamping rod 30 moves into position along the X direction, its positioning notch connects with positioning hole 1 and positioning hole 2. The locking cylinder 32 is activated to raise the locking rod 34, so that it penetrates positioning hole 1, positioning notch, and positioning hole 2 to form a locking and positioning connection. This prevents misalignment of the product, damage caused by excessive clamping, and loosening due to insufficient clamping force.

[0058] The magazine reel 35 comprises a reel 1 hinged on a stand 1, with retaining plates fixed on either side of the reel 1. A guide rod 1 is also fixed to the stand 1, positioned horizontally in front of the magazine reel 35's discharge port and parallel to the reel 1. The magazine strip is wound around the outer periphery of the reel 1 and extends outward, past the guide rod 1, and into the magazine conveyor.

[0059] The cassette conveyor device includes a conveyor frame with a conveyor track 36 mounted on its top surface. Infrared sensors 37 are positioned on opposite sides of the conveyor track 36. A conveyor motor 38 is mounted on the conveyor frame. A drive disc is fixedly mounted on the rotating shaft of the conveyor motor 38. The drive disc is surrounded by a ring-shaped array of drive protrusions. The cassette strip is inserted into and moved along the conveyor track 36. The infrared sensor 37 senses whether the cassette strip is moving normally. Several drive holes are evenly spaced along the edge of the cassette strip, with the spacing between adjacent drive holes equal to the spacing between adjacent drive protrusions. The conveyor motor 38 drives the drive disc in directional rotation, causing the multiple drive protrusions around the circumference to circulate, causing them to continuously engage with the drive holes and push forward one by one, thereby achieving directional transport of the cassette strip.

[0060] The material transfer and box loading device includes a vertical frame, affixed to a transverse motor 39. The transverse block of the transverse motor 39 is connected to a lifting cylinder 40. The telescopic end of the lifting cylinder 40 is connected to a material retrieving frame 41, on which a plurality of suction nozzles 42 are fixedly arranged. The transverse motor 39 drives the suction nozzles 42 to move back and forth between the secondary positioning device and the box conveying device; the lifting cylinder 40 drives the suction nozzles 42 to move up and down, thereby realizing the material retrieval and discharge operations.

[0061] The film reel 43 comprises a second reel hinged to a second stand. Stop discs are fixed to either side of the second reel. A second guide rod is also fixed to the second stand. The second guide rod is positioned horizontally in front of the film reel 43's discharge port, parallel to the second reel. The outer circumference of the second guide rod is secured to the guide discs. The film is wound around the outer circumference of the second reel and extends outward past the second guide rod into the cartridge conveyor.

[0062] The film laminating device sequentially comprises a film guide assembly and a film pressing assembly. The film guide assembly comprises film guide frames located on either side of the conveyor track 36.

[0064] Based on the first embodiment, the difference of this embodiment is that:

[0065] A packaging method for a packaging film laminating line comprises the following steps:

[0066] 1) Start the lifter 2 to drive the stacking rack 3 and the tray to rise. When the sensor senses that the tray plate 4 has risen to the right position, the lifter 2 stops. At this time, the limit rod 5 extends into the inlet and outlet of the tray insertion station, blocking the tray in the tray insertion station. The limit cylinder 6 pulls out the limit rod 5 to make the inlet and outlet of the corresponding tray insertion station unobstructed.

[0067] 2) Start the tray pulling motor 9 to drive the tray pulling frame 14 forward through the transmission belt assembly to connect the tray in the tray stacking frame 3, start the vertical cylinder 16 to drive the hook 17 to hook the bottom edge of the tray, start the tray pulling motor 9 to drive the tray pulling frame 14 through the transmission belt assembly to pull the tray backward, pull the tray out of the tray stacking frame 3 and slide it onto the guide slide 8;

[0068] 3) Start the transverse motor 19 to drive the suction nozzles 22 to move transversely to the top of the material tray, start the lifting cylinder 20 to drive the suction nozzles 22 to descend and suck some materials, the lifting cylinder 20 drives the suction nozzles 22 to rise, start the transverse motor 19 to drive the suction nozzles 22 to move transversely to the top of the insert plate 27;

[0069] The variable pitch cylinder 25 is activated to pull the final slider 23 and the suction nozzle 22 to move. When the relative telescopic displacement between the final clip 24 and the limit groove reaches the limit, the clip 24 engages and drives the next final slider 23 and the suction nozzle 22 to move, thereby transmitting one by one until the suction nozzles 22 as a whole are at their maximum spacing. The lifting cylinder 20 is activated to drive the suction nozzles 22 downward, and the materials are placed one by one into the cavity 27a of the insert plate 27.

[0070] 4) Start the clamping cylinder 29 to push the transmission plate 28, driving the X clamping rod 30 to slide along the X groove and clamp the X side of the product in the cavity 27a; synchronously drive the Y clamping block 31 to slide along the Y groove and clamp the Y side of the product in the cavity 27a;

[0071] When the X clamping rod 30 moves to its position along the X direction, its positioning notch is connected with the positioning hole 1 and the positioning hole 2; the locking cylinder 32 is started to raise the locking rod 34, so that the locking rod 34 passes through the positioning hole 1, the positioning notch and the positioning hole 2 to form a clamping position;

[0072] 5) The cartridge tape is pulled out from the cartridge reel 35, and the cartridge tape extends through the guide rod 1 and enters the conveying track 36 of the cartridge conveying device. The conveying motor 38 is started to drive the drive disc to rotate in a directional manner, so that the driving protrusions continuously engage with the driving holes of the cartridge tape and move forward one by one, thereby realizing the directional transportation of the cartridge tape;

[0073] 6) Start the traverse motor 2 39 to drive the suction nozzles 2 42 to move horizontally to above the insert plate 27 of the secondary positioning device, start the lifting cylinder 2 40 to drive the suction nozzles 2 42 to descend and suck the material, and then the lifting cylinder 2 40 drives the suction nozzles 2 42 to rise. Start the traverse motor 2 39 to drive the suction nozzles 2 42 to move horizontally to above the material box belt, and then start the lifting cylinder 2 40 to drive the suction nozzles 2 42 to descend and place the materials into the box cavity of the material box belt one by one.

[0074] 7) The film tape is pulled out from the film tape reel 43 and extended outward through the guide rod 2 to enter under the guide wheel 45. Then, it passes under the swing shaft 46 and contacts the surface of the material box tape, so that the film tape and the material box tape are transferred synchronously and pass through the bottom side of the film pressing wheel 48 for bonding and pressing;

[0075] 8) Start the take-up motor 49 to drive the take-up reel 50 to rotate. The film-applied box tape passes through the guide rod 3 and the guide rod 4 in sequence to change the conveying direction, and finally enters the take-up reel 50 for reeling.

[0076] Compared with the existing technology, this packaging film laminating production line and its packaging method have the following beneficial effects:

[0077] 1. Through the rational layout of the loading bin, tray transfer device, variable-distance material transfer device, secondary positioning device, material box reel, material box conveying device, material transfer and box loading device, film tape reel, film laminating device and material receiving device, a Y-shaped processing line is realized where the product supply line and the material box supply line intersect the loading and laminating line, thereby rationally utilizing the production space, occupying less area, and reducing the product transportation path. The overall structure is compact and highly integrated, which is conducive to optimizing the production process, improving efficiency and increasing output.

[0078] 2. Through the close cooperation of stacking tray loading and pulling tray transfer, the accurate movement of the tray is ensured while saving space, and the precise placement of materials in the tray is further guaranteed, thereby avoiding the vacuum phenomenon caused by misplacement of material, which ultimately causes the problem of empty packaging, and effectively ensuring the effectiveness of packaging.

[0079] 3. By coordinating variable-distance suction with secondary positioning, different spacing adjustments can be handled while ensuring accuracy after the distance change. Secondary positioning uses a single driver to synchronize two-way clamping, which not only reduces the number of driver settings and reduces costs, but also reduces fixing errors through synchronous clamping action, improving clamping efficiency. In addition, a clamping balance is formed in the two-way linkage, avoiding product damage caused by a single clamping tooth being too tight, or positioning errors caused by a single clamping tooth being too loose. The two-way linkage clamping further improves positioning accuracy.

[0080] 4. The tooth-tooth mechanism achieves directional conveying of the box belt, which helps control the conveying rhythm to coordinate with batch loading, effectively avoid the risk of empty boxes, and improve packaging yield. The use of strip conveying film laminating method simplifies the film laminating device, improves film laminating efficiency, and ensures film laminating accuracy.
