Background Art

[0002] With the development of technologies in the 3C industry, the demand for improving production capacity is increasing day by day. Therefore, it is required that automated equipment is simple and convenient to operate and can respond quickly. Before encapsulating a product, it is necessary to paste a label related to the product information at a set position. Currently, there is a product whose labeling position is on an inclined surface, which brings great difficulties to labeling. In the prior art, the patent publication number CN114715503A discloses a labeling method and a labeling production line. Although it also adopts a production method in a production line form, the object of its labeling is a packaging box, the labeling surface of the packaging box is a flat surface, and the overall shape of the packaging box is relatively regular, which is convenient for positioning. However, it is very difficult to achieve efficient full-automatic labeling on an inclined surface, and there is no automated equipment in the prior art that can achieve labeling on the inclined surface of small-sized products.

[0003] Therefore, it is necessary to provide a new full-automatic inclined surface labeling production line and a labeling method to solve the above problems.

[0005] The present invention realizes the above purpose through the following technical solutions: A full-automatic inclined surface labeling production line includes a carrier circulation conveyor, carriers conveyed on the carrier circulation conveyor, a feeding and loading unit, a labeling unit, a pressure maintaining unit, a detection unit, and a discharging and collecting unit arranged in sequence along the carrier circulation conveyor. The carrier circulation conveyor is sequentially provided with a loading station, a first flipping station, a labeling station, a pressure maintaining station, a detection station, a second flipping station, and a discharging station; the carrier includes a bottom plate, a rotating shaft rotatably arranged on the bottom plate, and a positioning fixture arranged on the rotating shaft; the positioning fixture is provided with a bearing and limiting groove imitating the shape of the product and an elastic pressing member for fixing the product in the bearing and limiting groove; a rotation driving unit for driving the rotating shaft to rotate is arranged at both the first flipping station and the second flipping station.

[0006] Compared with the prior art, the beneficial effects of a full-automatic inclined surface labeling production line and a labeling method of the present invention are as follows: By ingeniously designing the structure of the carrier, a rotating shaft is arranged on the carrier, and the positioning fixture for fixedly carrying the product is fixed on the rotating shaft. Before labeling, a first flipping station is designed, and the rotating shaft is driven to rotate by cooperating with the first flipping driving unit to realize the flipping of the product, flipping the inclined labeling surface on the product to a horizontal state, and then entering the subsequent labeling station, pressure maintaining station, and detection station for corresponding labeling, pressure maintaining, and detection operations; Before discharging, a second flipping station is designed, and the rotating shaft is driven back by cooperating with the second flipping driving unit to flip the positioning fixture to a horizontal state, facilitating the picking up, placing, and discharging of the product; In addition, a third support block and a fourth support block for keeping the positioning fixture in a set angle state are designed in the carrier. The third support block is fixedly arranged to support one side of the positioning fixture in the flipped state, and the fourth support block is designed to slide horizontally. When the fourth support block moves to the second position, it can support a first support block at the bottom of the positioning fixture, forming a clamping form together with the third support block to ensure the stability of the positioning fixture in the set angle state and be able to withstand the labeling pressure during labeling and the pressure maintaining pressure during pressure maintaining; An avoidance driving unit for driving the sliding of the fourth support block is designed at the corresponding station, and the fourth support plate is switched between the avoidance position and the support position by cooperating with the elastic member; Except for the feeding end and the discharging end of the entire production line where personnel need to supply a stack of trays and take away a stack of trays regularly, the rest are all automated operations, greatly improving the labeling efficiency; And accurate labeling operations on the inclined surface of the product are realized.

Specific implementation manner

[0034] Example 1:

[0035] Please refer to Figures 1-13 , this embodiment is a fully automatic inclined surface labeling production line 100, which includes a carrier circulation conveyor line 1, carriers 2 transported on the carrier circulation conveyor line 1, a feeding and loading unit 3, a labeling unit 4, a pressure maintaining unit 5, a detection unit 6, and a loading and unloading unit 7 arranged in sequence along the carrier circulation conveyor line 1. The carrier circulation conveyor line 1 is sequentially provided with a loading station, a first flipping station, a labeling station, a pressure maintaining station, a detection station, a second flipping station, and a loading and unloading station; the feeding and loading unit 3 is arranged corresponding to the loading station, the labeling unit 4 is arranged corresponding to the labeling station, the pressure maintaining unit 5 is arranged corresponding to the pressure maintaining station, the detection unit 6 is arranged corresponding to the detection station, and the loading and unloading unit 7 is arranged corresponding to the loading and unloading station.

[0036] Due to the special shape of the product and the special labeling position, in this embodiment, the carrier 2 is designed, which includes a bottom plate 21, a rotating shaft 22 rotatably arranged on the bottom plate 21, and a positioning fixture 23 arranged on the rotating shaft 22. The positioning fixture 23 has opposite first side A and second side B. The bottom of the first side A of the positioning fixture 23 is fixed on the rotating shaft 22. The positioning fixture 23 is provided with a carrying and limiting groove 231 imitating the shape of the product and an elastic pressing member 232 for fixing the product in the carrying and limiting groove 231. The product is carried and positioned by the positioning fixture 23 to ensure the accuracy of the product position. According to the labeling process requirements, by driving the rotating shaft 22 to rotate at an angle, the positioning fixture 23 can be driven to rotate, thereby realizing the adjustment of the product state, so as to flip the inclined surface for pasting the label on the product to a horizontal state, facilitating the labeling, pressure maintaining, and detection operations.

[0037] In this embodiment, the first side A and the second side B are distinguished relative to the rotating shaft 22. The first side A and the second side B are respectively located on both sides of the rotating shaft 22, forming a lever structure with the rotating shaft 22 as the rotation axis. The first side A can be infinitely close to the rotating shaft 22.

[0038] In order to ensure that the positioning fixture 23 maintains the state after rotating to the set angle state, the present embodiment further designs the carrier 2. Specifically, a first support block 24 is provided at the bottom of the second side B of the positioning fixture 23, a second support block 25 is fixedly provided on the bottom plate 21 to support the bottom of the second side B of the positioning fixture 23 so that the positioning fixture 23 remains horizontal, a third support block 26 supports the first side A after the positioning fixture 23 is flipped to the set angle state, and a fourth support block 27 supports the first support block 24 at the bottom of the second side B, the fourth support block 27 is slidably provided on the bottom plate 21 and moves horizontally between the first position and the second position, after the positioning fixture 23 is flipped to the set angle state, the fourth support block 27 is subjected to a force of an elastic member 28 to move from the first position to the second position and supports the first support block 24 at the second position. In some cases, the positioning jig 23 maintains a horizontal state under the joint support of the rotating shaft 22 and the second support block 25; in another case, the positioning jig 23 is driven to flip to the set angle state, and the fourth support block 27 moves to the second position to support the first support block 24. The first side A of the positioning jig 23 is pressed on the third support block 26. Through the joint action of the third support block 26 and the fourth support block 27, the positioning jig 23 is stably maintained at the set angle state without any shaking, thereby ensuring the stability of the product position during subsequent labeling, pressure holding and testing operations.

[0039] A first inclined surface structure is formed at the bottom of the first support block 24 . When the positioning fixture 23 is flipped to the set angle state, the first inclined surface structure is in a horizontal state and is in contact with the upper surface of the fourth support block 27 .

[0040] When the positioning jig 23 is in a horizontal state, the end of the fourth support block 27 supports the side elevation of the first support block 24 under the action of the elastic member 28. In order to ensure the position stability of the positioning jig 23 in a horizontal state, in this embodiment, a first limiting groove 241 is provided on the side elevation for the end of the fourth support block 27 to be inserted. The upper and lower heights of the first limiting groove 241 are equivalent to the thickness of the fourth support block 27. By inserting the end of the fourth support block 27 into the first limiting groove 241, the fourth support block 27 can limit the freedom of the first support block 24 in the upper and lower directions, thereby preventing the positioning jig 23 from rotating.

[0041] To ensure that the positioning fixture 23 reaches a completely horizontal state and reduce the gap between the positioning fixture 23 and the second support block 25 after being flipped to the horizontal state, in this embodiment, a first magnetic block 251 is embedded in the upper surface of the second support block 25, and a second magnetic block (not labeled in the figure) that attracts the first magnetic block 251 is correspondingly arranged at the bottom of the positioning fixture 23.

[0042] A first rotation driving unit 8 for driving the rotation of the rotating shaft 22 in the carrier 2 is provided at the first flipping station. The first rotation driving unit 8 can be arranged between the feeding and loading unit 3 and the labeling unit 4, or at the labeling unit 4. A second rotation driving unit 9 for driving the rotation of the rotating shaft 22 in the carrier 2 to return to the initial state is provided at the second flipping station. The second rotation driving unit 9 can be arranged between the detection unit 6 and the unloading and collecting unit 7, or at the unloading and collecting unit 7. By driving the rotating shaft 22 to rotate to a set angle state by the first rotation driving unit 8, the inclined labeling surface of the product is flipped to the horizontal state, and then subsequent labeling, pressure maintaining, and detection operations are performed in this state; before unloading and collecting, by driving the rotating shaft 22 to rotate back to the initial state by the second rotation driving unit 9, the product is flipped to the horizontal state, which is convenient for the subsequent unloading and collecting unit 7 to take out and unload the product, and is also convenient for the carrier 2 to be recycled in the initial state.

[0043] The first rotation driving unit 8 and the second rotation driving unit 9 have the same structure, and each includes a first cylinder 81, a first support plate 82 driven by the first cylinder 81 to move horizontally, a second cylinder 83 fixed on the first support plate 82, and a rotation driving block 84 driven by the second cylinder 83 to rotate around a horizontal axis. A transmission block 29 is arranged at the end of the rotating shaft 22, and a slot 291 for cooperating with the rotation driving block 84 for transmission is arranged on the end surface of the transmission block 29. The rotation driving block 84 is inserted into the slot 291 to achieve the rotational transmission connection with the transmission block 29. Under the drive of the second cylinder 83, the rotating shaft 22 can be driven to rotate.

[0044] When the positioning fixture 23 is flipped from the horizontal state to the set angle state, the fourth support block 27 needs to withdraw from the first limit groove 241 on the side surface of the first support block 24 so that the positioning fixture 23 can be flipped upward; and when the positioning fixture 23 is flipped from the set angle state to the horizontal state, the fourth support block 27 also needs to be removed from the second position to provide position avoidance for the falling of the first support block 24. Therefore, in this embodiment, an avoidance driving unit 10 for driving the fourth support block 27 to move from the second position to the first position is provided at both the first rotation driving unit 8 and the second rotation driving unit 9. The avoidance driving unit 10 includes a third air cylinder 101 and a wedge block 102 driven by the third air cylinder 101 to move up and down. A transmission roller 271 for cooperating with the wedge block 102 for transmission is provided on the fourth support block 27. The inclined surface structure on the wedge block 102 cooperates with the transmission roller 271 during the up and down movement to realize the horizontal movement of the transmission roller 271, thereby moving the fourth support block 27 from the second position to the first position. When the wedge block 102 is withdrawn, the fourth support block 27 returns to the second position under the action of the elastic member 28.

[0045] The structure of the carrier circulating conveyor line 1 can adopt a space-saving closed-loop linkage conveying device disclosed in the prior art with the patent number 2022100108576. Correspondingly, in this embodiment, a transmission tooth block 210 for cooperating with the transmission belt on the carrier circulating conveyor line 1 is provided at one end of the bottom plate 21 of the carrier 2, and rack structures for cooperating with the transmission belt are provided on both the upper and lower surfaces of the transmission tooth block 210.

[0046] To ensure the position stability of the carrier 2 at each operation station, positioning units 11 for fixing the position of the carrier 2 on the carrier circulating conveyor line 1 are provided at the feeding and loading unit 3, the labeling unit 4, the pressure maintaining unit 5, the detection unit 6, the unloading and receiving unit 7, the first rotation driving unit 8, and the second rotation driving unit 9. The positioning unit 11 includes a fourth air cylinder 111 and a limit caster 112 driven by the fourth air cylinder 111 to move horizontally. A second limit groove 211 for cooperating with the limit caster 112 for positioning is provided at the end of the bottom plate 21 of the carrier 2, and the second limit groove 211 and the transmission tooth block 210 are provided at opposite ends of the bottom plate 21. By extending the limit caster 112 into the second limit groove 211, the position of the carrier 2 can be fixed to prevent the carrier 2 from moving on the carrier circulating conveyor line 1.

[0047] A release driving piece 233 for driving the elastic pressing member 232 to be in an open state is slidably arranged on the positioning fixture 23. A second inclined surface structure 234 is formed on the sliding block of the elastic pressing member 232, and a third inclined surface structure 235 for cooperating with the second inclined surface structure 234 for transmission is arranged on the release driving piece 233. By horizontally pushing the release driving piece 233, the elastic pressing member 232 can be driven to move outwards to be in an open state. After the thrust on the release driving piece 233 is withdrawn, the elastic pressing member 232 is reset to the clamping state under the action of the spring to clamp the product in the bearing limit groove 231. In this embodiment, in order to facilitate placing the product into the bearing limit groove 231, a clamp opening unit 12 for pushing the release driving piece 233 to make the elastic pressing member 232 in an open state is arranged at the feeding and loading unit 3 and the unloading and receiving unit 7. The clamp opening unit 12 includes a fifth cylinder 121 and a clamp opening block 122 driven by the fifth cylinder 121 to move horizontally to push the release driving piece 233.

[0048] Since a certain downward pressure is applied to the product during the label pasting and pressure maintaining processes, the positioning fixture 23 can withstand a certain pressure in the set angle state and maintain the stability of the set angle state. Therefore, in this embodiment, through the arrangement of the third support block 26 and the fourth support block 27, the positioning fixture 23 flipped to the set angle state is clamped in a mutually resisting form, and a rigid mechanical angle limit is formed, providing conditions for bearing the label pasting pressure and the pressure maintaining pressure later, and ensuring the angle position stability and reliability of the positioning fixture 23.

[0049] In this embodiment, the feeding and loading unit 3 realizes the automatic feeding of the full-load trays and the automatic recycling of the empty trays, and takes out the products from the trays and places them in the carrier 2. The unloading and receiving unit 7 realizes the automatic feeding of the empty trays and the stacked receiving of the full-load trays, and takes out the products from the carrier 2 and places them in the trays for unloading and receiving.

[0050] The feeding and loading unit 3 includes a feeding module 31, a loading and handling module 32, a third inspection camera 33, and a transfer platform 34. The feeding module 31 mainly realizes functions such as feeding, tray separation, stacking and receiving of full-load trays and empty trays, and can adopt a tray automatic loading and unloading device disclosed in the patent No. 2021216329160 in the prior art. The loading and handling module 32 is used to take out the products from the trays and move them to the third inspection camera 33 for inspection. After the inspection is completed, they are placed on the transfer platform 34 and then transported from the transfer platform 34 to the carrier 2. The loading and handling module 32 includes a first handling mechanism 321 and a second handling mechanism 322. The first handling mechanism 321 is used to transport the products from the trays above the third inspection camera 33 and then transport and place them on the transfer platform 34. The second handling mechanism 322 is used to transport the products from the transfer platform 34 to the carrier 2. Both the first handling mechanism 321 and the second handling mechanism 322 include a second XY-axis transfer module 321 and a number of adsorption and picking components 322 arranged at the movable end of the second XY-axis transfer module 321. A vision camera is also provided in the second handling mechanism 322 to obtain the accurate position of the products on the transfer platform 34 and accurately place them into the positioning fixture 23. In this embodiment, the adsorption and picking component 322 has degrees of freedom in the Z-axis and R-axis to meet the picking of products in various different postures.

[0051] The unloading and receiving unit 7 includes a receiving module 71 and an unloading and handling module 72. The receiving module 71 has the same structure as the feeding module 31, and the unloading and handling module 72 has the same structure as the first handling mechanism 321.

[0052] The labeling unit 4 includes a feeder module 41, an adsorption and labeling module 42, and a first detection camera 43. In this embodiment, there are two feeder modules 41 arranged side by side. In other embodiments, the number can also be flexibly designed according to requirements and production beats. The feeder module 41 can adopt a device in the prior art that can realize automatic label unwinding, automatic peeling, and automatic bottom film recycling. The adsorption and labeling module 42 includes a first XY-axis transfer module 421, a number of labeling adsorption modules 422 arranged at the movable end of the first XY-axis transfer module 421, and a second detection camera 423. The labeling adsorption module 422 includes a first motor 4221 and a second motor 4222, a lifting rotating shaft 4223 that moves up and down driven by the first motor 4221 and rotates driven by the second motor 4222, and an adsorption block 4224 fixed to the bottom of the lifting rotating shaft 4223. The first detection camera 43 is used to detect the label appearance and label information. The second detection camera 423 is used to obtain the position of the label for accurate suction, and at the same time to obtain the position of the product in the carrier 2 to facilitate accurate label pasting. Multiple labeling adsorption modules 422 can carry multiple labels to complete the labeling of multiple products at the labeling position, improving the labeling efficiency of a single transfer and handling operation.

[0053] The pressure-holding unit 5 is mainly used to perform pressure-holding on the pasted label to improve the paste firmness of the label. It includes a third motor 51, a second support plate 52 that moves up and down driven by the third motor 51, a mounting block 53 that slides up and down on the second support plate 52, a pressure-holding head 54 arranged at the bottom of the mounting block 53 and conforming to the shape of the label, and a counterweight 55 fixed to the mounting block 53. The mounting block 53 is hung on the second support plate 52 through a hanging rod 56. When performing the pressure-holding operation, the third motor 51 drives the second support plate 52 to descend. First, the pressure-holding head 54 touches the surface of the label, and then the third motor 51 continues to drive the second support plate 52 to descend a certain distance. At this time, the mounting block 53 and the counterweight 55 rely on the pressure-holding head 54 to completely sit on the label, and the second support plate 52 does not have a lifting force on the mounting block 53. The gravity of the mounting block 53 and the counterweight 55 is used to perform the pressure-holding operation on the label to make the label paste firmly.
