[0004] Based on this, the present invention designs a production line for packaging displays and a packaging method thereof to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a production line for packaging displays and a packaging method thereof.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A production line for packaging displays includes a roller conveyor line;

[0008] The roller conveyor line is sequentially equipped with the following units according to the material conveying direction: a disassembly tray unit for splitting stacked trays or boxes, a padding unit for placing protective pads on the boxes to be split, a boxing unit for placing desiccant in the boxes, a display screen loading unit for loading the display screen into the boxes, a cover unit for sealing the boxes with a top cover, and a bagging unit for bagging and packaging the boxes.

[0009] The roller conveyor line is equipped with multiple roller support frames for carrying materials, as well as multiple movable baffles. The discharge end and the inlet end of the roller conveyor line are equipped with lifting and positioning machines.

[0010] The bagging unit includes a bag feeding device, a vacuum heat sealing device, a waste cutting and collection device, a labeling device, and a strapping mechanism.

[0011] Furthermore, the material unloading unit includes a roller support frame, a lifting support machine, a lifting positioning machine, a clamping device, a material tray transfer device, and a first detection device for detecting the front and back of the material box. The roller support frame is installed on the lifting support machine, and the lifting positioning machine is provided on the lower side of the roller support frame.

[0012] Furthermore, the gasket feeding unit includes a gasket transfer device, a positioning detection platform, a second detection device for positioning and detecting the gaskets, and a centering device. The gasket transfer device is provided in two sets.

[0013] Furthermore, the packing and loading unit includes a roller support frame, a lifting support machine, a lifting positioning machine, a material box transfer device, and a desiccant feeding mechanism. The roller support frame is installed on the lifting support machine, and there are two sets of lifting support machines and lifting positioning machines, located at the desiccant feeding station and the display screen feeding station, respectively.

[0014] Furthermore, the desiccant feeding mechanism includes a feeding vibratory plate, a turning device, a four-axis robot, and a placement plate. There are two sets of placement plates, and the placement plate has multiple placement grooves for placing the desiccant.

[0015] Furthermore, the display screen feeding unit includes a flipping material feeder, a first code reading device, a feeding platform, a six-axis robot, and a third detection device for positioning and detecting the display screen. There are two third detection devices, which are located on the movement path of the six-axis robot.

[0016] Furthermore, the cover unit includes a lifting material support machine, a lifting positioning machine, a fourth detection device for detecting the reverse insertion of the display screen inside the material box, a material hopper loading device, a top cover handling device, a fifth detection device for detecting the positioning of the top cover, and a top cover labeling mechanism.

[0017] Furthermore, the top cover labeling mechanism includes a label printer, a top cover labeling device, and a second barcode reader for reading the topmost label of the stacked bins.

[0018] Furthermore, the belt-bundling mechanism includes a belt-bundling machine and a rotary lifting mechanism, with the rotary lifting mechanism located on the roller conveyor line following the belt-bundling machine.

[0019] To better achieve the objectives of this invention, this invention also provides a packaging method for a production line used for packaging displays, comprising the following steps:

[0020] Step 1: The material bins are stacked and loaded onto the roller support frame, and the roller support frame is connected to the roller conveyor line through the inlet and outlet lifting unit;

[0021] Step 2: The roller conveyor transports the stacked boxes to the roller support frame of the dismantling tray unit. The lifting support machine raises the boxes, and the movable baffle, together with the lifting positioning machine, keeps the boxes centered until the top box reaches the set height. Then, the clamping device positions and clamps the top box. The tray transfer device grabs the top box and moves it to the roller conveyor line behind the dismantling tray unit. During the transfer, the first detection device detects the front and back of the box.

[0022] Step 3: The roller conveyor line transports the material box to the gasket feeding unit. A set of gasket transfer equipment transports the gasket to the positioning and detection platform, and the second detection device detects whether the gasket is in the set position to perform positioning detection on the gasket. After the detection is completed, another set of gasket transfer equipment grabs the gasket from the positioning and detection platform and moves it to the material box on the roller conveyor line. At the same time, the movable baffle works with the centering equipment to keep the material box in position.

[0023] Step 4: The roller conveyor line transports the material box to the boxing and loading unit. The material box is transported to the roller support frame at the desiccant loading station. The lowering support machine drives the roller support frame to lower to the set position. The lifting and positioning machine positions the material box. The four-axis robot grabs a set of desiccant from the placement tray and places it into the material box at one time.

[0024] Step 5: The material box transfer equipment transports the loaded material box to the roller support frame at the display screen loading station; the flipping support machine carries the display screen through the first code reading device to read the mark on the display screen, then flips the display screen and places it on the feeding platform. The six-axis robot grabs the display screen from the feeding platform, and the display screen is positioned and detected by two third detection devices. Finally, the display screen is installed into the material box at the display screen loading station.

[0025] Step Six: The roller conveyor transports the loaded bins to the cover unit. The bins undergo a reverse insertion test by the fourth detection device, which checks if the loading direction of the display screen inside the bin is the set direction. The top cover labeling device picks up the printed label from the label printer and applies the label to the top cover on the hopper loading device. The top cover labeling device also identifies the label through the second barcode reader. The top cover transport device moves the labeled top cover to the bin that has completed the reverse insertion test, completing the bin capping process.

[0026] Step 7: The roller conveyor transports the material box to the bagging unit. The bag feeding equipment grabs the bag and moves the cornered bag to the vacuum heat sealing equipment. On the vacuum heat sealing equipment, the box is put into the opened bag, and then the packaging is heat sealed. The waste cutting and collection equipment cuts off the excess bag and collects the waste. The bagged box is labeled when it passes through the labeling equipment. After the bagged box passes through the strapping machine to complete the strapping in one direction, the box is rotated 90 degrees by the rotating lifting mechanism. Then the box is returned to the strapping machine to be strapped in the other direction.

[0027] Step 8: The roller conveyor line transports the packaged boxes to the roller support frame, and the boxes are discharged through the inlet and outlet lifting unit.

[0028] The present invention has the following technical effects:

[0029] 1. In this invention, material boxes are stacked and loaded onto a roller support frame. The roller support frame is connected to the roller conveyor line via an inlet / outlet lifting unit. The material boxes are conveyed to each unit via the roller conveyor line. Movable baffles are used to block and position the material boxes at set positions. The unpacking unit detects and separates the stacked material boxes. The padding unit places pads for protecting the display screen on the separated material boxes. The boxing and loading unit places desiccant inside the material boxes. The display screen loading unit loads the display screen into the material boxes. The lid-closing unit seals the material boxes with the top cover. The bagging and packaging unit bags and packages the boxes containing the materials. Finally, the finished products are conveyed to the roller support frame and discharged via the inlet / outlet lifting unit. This production line allows for smooth connection between units via the roller conveyor line, completing the automatic boxing and packaging of materials, saving labor, reducing operational difficulty, improving production capacity and yield, facilitating timely monitoring of the product status in the production line by the monitoring system, and ensuring high operational precision without easily damaging precision products.

[0030] 2. In this invention, the strapping machine can only perform strapping in one direction. After the bagged box is strapped in one direction by the strapping machine, the box is rotated 90 degrees by the rotating lifting mechanism, and then the box is returned to the strapping machine to perform strapping in the other direction.

Finally, the finished product is conveyed to roller support frame 101 and discharged via inlet / outlet lifting unit 102. This production line allows for smooth connection between units via roller conveyor line 1, completing the automatic boxing and packaging of materials, saving labor, reducing operational difficulty, improving production capacity and yield, and facilitating timely monitoring of the product status in the production line by the monitoring system.

[0050] In some embodiments, such as Figure 2-9 As shown, this is a preferred embodiment of the present invention.

[0051] The unloading tray unit 4 includes a roller support frame 101, a lifting support machine 2, a lifting positioning machine 3, a clamping device 41, a tray transfer device 42, and a first detection device 43. The roller support frame 101 is installed on the lifting support machine 2, and the lifting positioning machine 3 is set on the lower side of the roller support frame 101. Stacked trays or boxes enter the roller support frame 101 from the roller conveyor line 1. The lifting support machine 2 lifts the boxes, and the movable baffle 103, in conjunction with the lifting positioning machine 3, keeps the boxes centered until the top box reaches the set height. Then, the clamping device 41 positions and clamps the top box. The tray transfer device 42 grabs the top box and transports it to the roller conveyor line 1 behind the unloading tray unit 4. During the transport process, the first detection device 43 detects the front and back of the box.

[0052] The gasket feeding unit 5 includes a gasket transfer device 51, a positioning detection platform 52, a second detection device 53, and a centering device 54. The gasket transfer device 51 is provided in two sets. One set of gasket transfer device 51 transports the gasket to the positioning detection platform 52 and uses the second detection device 53 to detect whether the gasket is in the set position to perform positioning detection on the gasket. After the detection is completed, the other set of gasket transfer device 51 grabs the gasket from the positioning detection platform 52 and transports it to the material box on the roller conveyor line 1. At the same time, the movable baffle 103 works in conjunction with the centering device 54 to keep the material box in position, ensuring the accuracy of gasket feeding.

[0053] The box loading unit 6 includes a lifting and supporting machine 2, a lifting and positioning machine 3, a box transfer device 61, and a desiccant feeding mechanism. There are two sets of lifting and supporting machines 2 and lifting and positioning machines 3, located at the desiccant feeding station and the display screen feeding station, respectively. The roller conveyor line 1 transports the box to the roller support frame 101 at the desiccant feeding station. The lifting and supporting machine 2 drives the roller support frame 101 to a set position to facilitate subsequent loading operations. The lifting and positioning machine 3 ensures that the position of the box does not shift. Then, the desiccant feeding mechanism loads a set amount of desiccant into the box. The box transfer device 61 transports the loaded box to the roller support frame 101 at the display screen feeding station.

[0054] The desiccant feeding mechanism includes a feeding vibratory plate 62, a flipping device 63, a four-axis robot 64, and a placement plate 65. The feeding vibratory plate 62 is used for feeding the desiccant. There are two sets of placement plates 65, and multiple placement grooves are provided in the placement plates 65. After the flipping device 63 grabs the desiccant fed by the feeding vibratory plate 62, it flips the desiccant. The four-axis robot 64 places the flipped desiccant into the placement grooves until all the placement grooves in one set of placement plates 65 are filled with desiccant. When the material box to be loaded reaches the set position, the four-axis robot 64 grabs the desiccant in one set of placement plates 65 and places it into the material box.

[0055] The display screen loading unit 7 includes a flipping and palletizing machine 71, a first barcode reader 72, a feeding platform 73, a six-axis robot 74, and a third detection device 75. The two third detection devices 75 are set on the movement path of the six-axis robot 74. The display screen is loaded on the flipping and palletizing machine 71. After the first barcode reader 72 reads the mark on the display screen, the flipping and palletizing machine 71 flips the display screen and places it on the feeding platform 73. The six-axis robot 74 picks up the display screen from the feeding platform 73, performs positioning detection on the display screen through the two third detection devices 75, and finally loads the display screen into the material box of the display screen loading station.

[0056] The cover unit 8 includes a lifting material feeder 2, a lifting positioning machine 3, a fourth detection device 81, a hopper loading device 82, a top cover transport device 83, a fifth detection device 84, a label printer 85, a top cover labeling device 86, and a second code reader 87. The lifting material feeder 2 and the lifting positioning machine 3 work together to supply the top cover. The label printer 85 prints the label on the top cover. After the material is loaded, the hopper undergoes a reverse insertion test by the fourth detection device 81, which checks if the loading direction of the display screen inside the hopper is the set direction. The hopper loading device 82 lifts the top cover from the top cover supply point. The top cover labeling device 86 picks up the printed label from the label printer 85 and applies the label to the top cover on the hopper loading device 82. The label is then identified by the second code reader 87. The top cover transport device 83 moves the labeled top cover to the hopper that has completed the reverse insertion test and uses the fifth detection device 84 to detect the position of the top cover, thus completing the hopper loading process.

[0057] The bagging unit 9 includes a bag feeding device 91, a vacuum heat sealing device 92, a waste cutting and collection device 93, a labeling device 94, and a strapping mechanism. The bag feeding device 91 picks up the bag and moves the cornered bag to the vacuum heat sealing device 92. On the vacuum heat sealing device 92, the box is put into the opened bag, and then the packaging is heat sealed. The waste cutting and collection device 93 cuts off the excess bag and collects the waste. When the bagged box passes through the labeling device 94, it is labeled. Finally, the strapping mechanism straps the bagged box.

[0058] The strapping mechanism includes a strapping machine 95 and a rotary lifting mechanism 96. The strapping machine can only perform strapping in one direction. After the bagged box is strapped in one direction by the strapping machine 95, the box is rotated 90 degrees by the rotary lifting mechanism 96, and then the box is returned to the strapping machine 95 to perform strapping in the other direction.

[0059] In some embodiments, such as Figure 1-9 As shown, a packaging method for a production line used for packaging displays includes the following steps:

[0060] Step 1: The material boxes are stacked and loaded on the roller support frame 101, and the roller support frame 101 is connected to the roller conveyor line 1 by the inlet / outlet lifting unit 102.

[0061] Step 2: Roller conveyor 1 transports the stacked boxes to the roller support frame 101 of the dismantling tray unit 4. The lifting support machine 2 lifts the boxes, and the movable baffle 103, in conjunction with the lifting positioning machine 3, keeps the boxes centered until the top box reaches the set height. Then, the clamping device 41 clamps and positions the top box, and the tray transfer device 42 grabs the top box and moves it to the roller conveyor 1 behind the dismantling tray unit 4. During the transfer, the first detection device 43 detects the front and back of the boxes.

[0062] Step 3: Roller conveyor 1 transports the material box to the gasket feeding unit 5. A set of gasket transfer devices 51 transports the gasket to the positioning detection platform 52 and detects whether the gasket is in the set position through the second detection device 53. The gasket is then positioned. After the detection is completed, another set of gasket transfer devices 51 grabs the gasket from the positioning detection platform 52 and moves it into the material box on roller conveyor 1. At the same time, the movable baffle 103 works with the centering device 54 to keep the material box in position.

[0063] Step 4: Roller conveyor 1 transports the material box to the boxing and loading unit 6. The material box is transported to the roller support frame 101 at the desiccant loading station. The lowering support machine 2 drives the roller support frame 101 to lower to the set position. The lifting and positioning machine 3 positions the material box. The four-axis robot 64 grabs a set of desiccant from the placement tray 65 and places it into the material box.

[0064] Step 5: The material box transfer device 61 transports the loaded material box to the roller support frame 101 of the display screen loading station; the flipping support machine 71 carries the display screen through the first code reading device 72 to read the mark on the display screen, and then flips the display screen and places it on the feeding platform 73. The six-axis robot arm 74 grabs the display screen from the feeding platform 73, and the display screen is positioned and detected by two third detection devices 75. Finally, the display screen is installed into the material box of the display screen loading station.

[0065] Step Six: Roller conveyor 1 transports the loaded hopper to the cover unit 8. The hopper undergoes a reverse insertion test via the fourth detection device 81, which checks if the loading direction of the display screen inside the hopper is the set direction. The top cover labeling device 86 picks up the printed label from the label printer 85 and applies the label to the top cover on the hopper loading device 82. The top cover labeling device 86 also identifies the label via the second barcode reader 87. The top cover transport device 83 moves the labeled top cover to the hopper that has completed the reverse insertion test, thus completing the hopper capping process.

[0066] Step 7: Roller conveyor 1 transports the material box to the bagging and packaging unit 9. The bag feeding device 91 grabs the bag and moves the cornered bag to the vacuum heat sealing device 92. On the vacuum heat sealing device 92, the box is put into the opened bag, and then the packaging is heat sealed. The waste cutting and collection device 93 cuts off the excess bag and collects the waste. The bagged box is labeled when it passes through the labeling device 94. After the bagged box passes through the strapping machine 95 to complete the strapping in one direction, the box is rotated 90 degrees by the rotating lifting mechanism 96. Then the box is returned to the strapping machine 95 to be strapped in the other direction.

[0067] Step 8: Roller conveyor line 1 transports the packaged boxes to roller support frame 101, and discharges them through inlet / outlet lifting unit 102.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

Step 5: The material box transfer device (61) transports the loaded material box to the roller support frame (101) of the display screen loading station; the flipping support machine (71) carries the display screen through the first code reading device (72) to read the mark on the display screen, and then flips the display screen and places it on the feeding platform (73). The six-axis robot (74) grabs the display screen from the feeding platform (73), and performs positioning detection on the display screen through two third detection devices (75). Finally, the display screen is loaded into the material box of the display screen loading station. Step 6: The roller conveyor (1) transports the loaded hopper to the cover unit (8). The hopper undergoes a reverse insertion test by the fourth detection device (81). The test shows that the loading direction of the display screen inside the hopper is the set direction. The top cover labeling device (86) grabs the printed label from the label printer (85) and applies the label to the top cover on the hopper loading device (82). The top cover labeling device (86) identifies the label through the second code reading device (87). The top cover transport device (83) moves the labeled top cover to the hopper that has completed the reverse insertion test, thus completing the hopper cover loading work. Step 7: The roller conveyor (1) transports the material box to the bagging unit (9). The bag feeding device (91) grabs the bag and moves the cornered bag to the vacuum heat sealing device (92). On the vacuum heat sealing device (92), the box is put into the opened bag. Then the packaging is heat sealed, and the excess bag is cut off by the waste cutting and collection device (93). At the same time, the waste is collected. The bagged box is labeled when it passes through the labeling device (94). After the bagged box passes through the strapping machine (95) to complete the strapping in one direction, the box is rotated 90 degrees by the rotating lifting mechanism (96). Then the box is returned to the strapping machine (95) to perform strapping in another direction. Step 8: The roller conveyor (1) transports the packaged boxes to the roller support frame (101) and discharges them through the inlet and outlet lifting unit (102).
