[0026] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0027] See also Figure 1The present application provides an embodiment of an assembly line operation system 1000, which includes a conveyor belt device 200 and a packaging box covering device 100. The packaging box covering device 100 is arranged on the conveyor belt device 200. The conveyor belt device 200 is configured to convey the box body 301 and the box cover 302 of the packaging box into the interior of the packaging box covering device 100 in the conveying direction M, and the packaging box covering device 100 is used to complete the covering of the box cover 302 and the box body 301, so that the conveyor belt device 200 continues to convey the assembled packaging box to the next workstation.

[0028] For the above-mentioned packaging box closing device 100, please refer to Figure 1 The packaging box cover closing device 100 includes a frame 10, a first detection assembly 20, a first stop assembly 30 and a suction assembly 40. The interior of the frame 10 has a relative first position 10a and a second position 10b. The first detection assembly 20 is arranged on the frame 10, and the first detection assembly 20 is configured to detect whether the box body 301 of the packaging box passes through the first position 10a, and detect whether the box cover 302 of the packaging box reaches the second position 10b. The first stop assembly 30 is arranged on the frame 10, and the first stop assembly 30 is configured to move to block the box body 301 when the box body 301 passes through the first position 10a, so that the box body 301 is stationary relative to the frame 10. The suction assembly 40 is disposed on the frame 10. When the first stop assembly 30 blocks the box body 301 at the first position 10a, the box cover 302 corresponding to the box body 301 will be blocked by the box body 301 at the second position 10b. The suction cup assembly is configured such that when the box cover 302 reaches the second position 10b, the suction cup assembly absorbs the box cover 302 and moves to be assembled with the box body 301 at the first position 10a. In this way, the mechanized assembly of the box body 301 and the box cover 302 can be realized, eliminating manual assembly and effectively improving the efficiency of production assembly.

[0029] In some embodiments, see Figure 1 and Figure 2 The frame 10 is a frame structure formed by splicing a plurality of pipe bodies. The frame 10 has an inlet end 11 and an outlet end 12 opposite to each other in the direction of the conveyor belt device 200 conveying the packaging box. The box body 301 and the box cover 302 of the packaging box enter the interior of the frame 10 from the inlet end 11. The assembled packaging box exits the interior of the frame 10 from the outlet end 12 and continues to be conveyed to the next process position. The first position 10a inside the frame 10 is close to the outlet end 12, and the second position 10b is close to the inlet end 11. Therefore, along the conveying direction M of the transmission belt, the box body 301 of the packaging box is located in front of the box cover 302.

[0030] For the above-mentioned suction assembly 40, see Figure 2 and Figure 3The suction assembly 40 includes a first component 41, a second component 42 and a suction cup component 43, wherein the first component 41 is disposed on the frame 10, the second component 42 is disposed on the first component 41, and the suction cup component 43 is disposed on the second component 42. The first component 41 is configured to drive the second component 42 and the suction cup component 43 to reciprocate along a first direction X, and the second component 42 is configured to drive the suction cup component 43 to reciprocate along a second direction Y, wherein the first direction X is substantially perpendicular to the second direction Y. In some embodiments, the first direction X may be parallel to the conveying direction M in which the conveyor belt device 200 conveys the packaging box, and the second direction Y is perpendicular to the surface of the transmission belt in the conveyor belt device 200. Of course, in other embodiments, the first direction X may be perpendicular to the conveying direction M in which the conveyor belt device 200 conveys the packaging box, and the second direction Y is perpendicular to the surface of the transmission belt in the conveyor belt device 200.

[0031] The following description takes the first direction X being parallel to the conveying direction M of the conveyor belt device 200 for conveying the packaging box as an example. Figure 2 The first component 41 includes a first fixing member 411 and a first cylinder 412. The first fixing member 411 is connected to the frame 10 and the first cylinder 412 respectively to fix the first cylinder 412 on the frame 10. The first telescopic portion 4121 in the first cylinder 412 reciprocates and telescopes along the first direction X. Please refer to Figure 3 The second component 42 includes a second fixing member 421 and a second cylinder 422. The second fixing member 421 is connected to the first telescopic portion 4121 and the second cylinder 422 of the first cylinder 412, respectively, so as to fix the second cylinder 422 on the first telescopic portion 4121 and reciprocate synchronously with the first telescopic portion 4121 in the first direction X. The second telescopic portion 4221 in the second cylinder 422 reciprocates and telescopes along the second direction Y. The suction cup component 43 includes a third fixing member 431 and a suction cup 432. The third fixing member 431 is connected to the second telescopic portion 4221 of the second cylinder 422 and the suction cup 432, respectively, so as to fix the suction cup 432 on the second telescopic portion 4221, so that the suction cup 432 and the second telescopic portion 4221 synchronously telescope in the second direction Y. The suction cup 432 is connected to an external suction source, so that when the suction cup 432 abuts against the box cover 302, negative pressure can be generated to suck the box cover 302.

[0032] It is worth noting that in the above embodiment, the cylinder is used as a power source to drive the suction cup 432 to move. In other embodiments, the power can be transmitted through guide rails and pulleys, or racks and motors, so as to drive the suction cup 432 to move in the first direction X and the second direction Y.

[0033] In some embodiments, please refer to Figure 3, the second component 42 further includes a first guide member 423, which is connected to the frame 10 and the second fixing member 421 respectively, and the first guide member 423 can move relatively on the frame 10 along the first direction X. As an example, the first guide member 423 is sleeved on the tube body of the frame 10, and the first guide member 423 is used to guide the first telescopic part 4121 in the first cylinder 412. At the same time, the first guide member 423 can also transfer the gravity of the second cylinder 422 and the suction cup component 43 to the frame 10, that is, the first guide member 423 has a pulling force on the second cylinder 422 and the suction cup component 43, thereby avoiding the first telescopic part 4121 of the first cylinder 412 from shaking violently when performing telescopic movement, and reducing the suction accuracy and stability of the suction cup component 43.

[0034] In some embodiments, see Figure 3 , the suction cup component 43 also includes a first air pipe 433, a second air pipe 434 and a first elastic member 435. The first air pipe 433 is arranged on the third fixing member 431, the second air pipe 434 is sleeved and connected with the first air pipe 433 and can move in an axial direction relative to the first air pipe 433, the suction cup 432 is arranged at the end of the second air pipe 434, and the first air pipe 433, the second air pipe 434 and the suction cup 432 are in gas communication. The first elastic member 435 is sleeved on the outside of the first air pipe 433 and the second air pipe 434, and the first elastic member 435 is respectively connected to the second air pipe 434 and the third fixing member 431. Or in other examples, the first elastic member 435 is respectively connected to the suction cup 432 and the first air pipe 433. Such a structure can enable the first air pipe 433 and the second air pipe 434 to telescope, so that the second telescopic part 4221 of the second air cylinder 422 can play a buffering role when driving the suction cup 432 to move along the second direction Y and abut against the box cover 302, thereby preventing the suction cup 432 from directly hitting the surface of the box cover 302, and at the same time, the descending height of the suction cup 432 can be adjusted at any time to overcome the problem that the suction cup 432 cannot absorb the box cover 302 due to the size error of the box cover 302. The first elastic member 435 is provided to buffer the movement between the first air pipe 433 and the second air pipe 434 and provide elastic force for the reset movement of the two.

[0035] For the first limiting assembly 30, please refer to Figure 2 and Figure 3The first limiting assembly 30 is arranged near the outlet end 12 of the frame 10. The first limiting assembly 30 includes a third cylinder 31 and a first blocking member 32. The third cylinder 31 is arranged at the outlet end 12 of the frame 10. The third telescopic portion 311 of the third cylinder 31 performs telescopic movement along the second direction Y. The first blocking member 32 is arranged at the third telescopic portion 311 and performs telescopic movement synchronously with the third telescopic portion 311, so that the first blocking member 32 has a first release position 32a and a first blocking position 32b relative to the frame 10. Please refer to Figure 4 When the first blocking member 32 is in the first release position 32a, the box body 301 and the box cover 302 can pass through the first limiting assembly 30 under the conveying action of the conveyor belt, and when the first blocking member 32 is in the first blocking position 32b, the box body 301 is stopped at the first position 10a, so that the first cylinder 412 and the second cylinder 422 can cooperate to drive the suction cup 432 to suck the box cover 302 at the second position 10b and cover the box body 301 at the first position 10a.

[0036] In the above embodiment, the first position-limiting assembly 30 is to switch the first blocking member 32 between the first blocking position 32b and the first release position 32a by the linear telescopic motion of the cylinder. In other examples, the first position-limiting assembly 30 can also be to drive the first blocking member 32 to rotate relative to the frame 10 by a motor or the like to realize the switching of the first blocking member 32 between the first blocking position 32b and the first release position 32a.

[0037] For the first detection component 20 mentioned above, please refer to Figure 2 The first detection component 20 includes a first sensor 21 and a second sensor 22. The first sensor 21 is arranged on the frame 10 and corresponds to the first position 10a. The first sensor 21 is electrically connected to the third cylinder 31 of the first limiting component 30. The first sensor 21 is used to detect whether there is a box body 301 on the first position 10a. If so, a blocking signal is sent to the third cylinder 31 so that the third cylinder 31 drives the first limiting member to move to the first blocking position 32b. The second sensor 22 is arranged on the frame 10 and corresponds to the second position 10b. The second sensor 22 is electrically connected to the suction component 40. The second sensor 22 is used to detect whether there is a box cover 302 at the second position 10b. If so, a closing signal is sent to the suction component 40, so that the first cylinder 412 and the second cylinder 422 work together to drive the suction cup component 43 to move, so as to suck the box cover 302 on the second position 10b to the top of the box body 301 at the first position 10a. Under the action of gravity of the box cover 302 and / or the driving action of the second cylinder 422, the box cover 302 is closed and connected with the box body 301 to complete the assembly of the two. At this time, the first blocking member 32 switches to the first release position 32a. Under the driving action of the conveyor belt, the box body 301 and the box cover 302 continue to move together.

[0038] In some embodiments, see Figure 1 The packaging box closing device 100 further includes a first pushing assembly 50 and a second pushing assembly 60. The first pushing assembly 50 is disposed on the frame 10 and corresponds to the first position 10a. The first pushing assembly 50 is configured to position and fix the box body 301 at the first position 10a. The second pushing assembly 60 is disposed on the frame 10 and corresponds to the second position 10b. The second pushing assembly 60 is configured to position and fix the box cover 302 at the second position 10b, wherein the center of the positioned box body 301 and the center of the positioned box cover 302 are collinearly distributed along the first direction X. By providing the first pushing assembly 50 and the second pushing assembly 60, the box body 301 and the box cover 302 can be relatively fixed, and the centers of the two can be colinearly distributed in the first direction X, so that when the suction cup component 43 sucks the box cover 302 and moves it above the box body 301, the two can be smoothly closed and connected, thereby improving the accuracy of the closing connection between the two and reducing the probability that the box cover 302 cannot be completely closed and connected with the box body 301 or gets stuck during the closing process.

[0039] As an example, see Figure 2 The frame 10 has a first side portion 13 and a second side portion 14 opposite to each other. The first push assembly 50 includes a fourth cylinder 51 and a first positioning member 52. The fourth cylinder 51 is disposed at one of the first side portion 13 and the second side portion 14, and the first positioning member 52 is disposed at the other of the first side portion 13 and the second side portion 14. That is, the fourth cylinder 51 and the first positioning member 52 are disposed opposite to each other, so that the fourth telescopic portion 511 of the fourth cylinder 51 and the first positioning member 52 can respectively abut against the two sides of the box body 301. The second push assembly 60 includes a fifth cylinder 61 and a second positioning member 62. The fifth cylinder 61 is disposed at one of the first side portion 13 and the second side portion 14, and the second positioning member 62 is disposed at the other of the first side portion 13 and the second side portion 14. That is, the fifth cylinder 61 and the second positioning member 62 are disposed opposite to each other, so that the fifth telescopic portion 611 of the fifth cylinder 61 and the second positioning member 62 can respectively abut against the two sides of the box cover 302.

[0040] Specifically, when the first sensor 21 detects that there is a box body 301 at the first position 10a and the first blocking member 32 blocks the box body 301, the fourth telescopic portion 511 extends to abut the box body 301 against the first positioning member 52 to achieve positioning and fixing of the box body 301. When the second sensor 22 detects that there is a box cover 302 at the second position 10b, the fifth telescopic portion 611 extends to abut the box cover 302 against the second positioning member 62 to achieve positioning and fixing of the box cover 302. The center of the positioned box body 301 and the center of the positioned box cover 302 are collinearly distributed along the first direction X. At this time, the first cylinder 412 and the second cylinder 422 jointly drive the suction cup component 43 to suck the box cover 302 and move it to the top of the box body 301 to achieve the covering connection between the two.

[0041] In some embodiments, a buffer layer may be provided on the surface of the fourth telescopic portion 511 and the first positioning member 52 that contacts the box body 301 to avoid directly impacting the surface of the box body 301 and scratching the surface of the box body 301. Similarly, a buffer layer may be provided on the surface of the fifth telescopic portion 611 and the second positioning member 62 that contacts the box cover 302 to avoid directly impacting the surface of the box cover 302 and scratching the surface of the box cover 302.

[0042] In some embodiments, see Figure 1 The packaging box closing device 100 further includes a second limiting assembly 70, which is disposed on the frame 10. Along the moving direction of the packaging box, the first pushing assembly 50 and the second limiting assembly 70 are respectively disposed on both sides of the second pushing assembly 60. The second limiting assembly 70 is configured to block the next box body 301 that is about to enter the first position 10a when the first position 10a has the box body 301. Since when the first position 10a has the box body 301, it indicates that the closing operation of the box body 301 and the box cover 302 is being performed at the first position 10a and the second position 10b, in order to avoid interference caused by the entry of the next box body 301, the second limiting assembly 70 can be disposed on the side of the second pushing assembly 60 close to the entrance end 11 of the frame 10 to prevent the entry of the next box body 301.

[0043] As an example, see Figure 4The second limiting assembly 70 includes a sixth cylinder 71 and a second blocking member 72. The sixth cylinder 71 is arranged on the first side portion 13 or the second side portion 14 or other areas of the frame 10. The sixth telescopic portion 711 in the sixth cylinder 71 can perform telescopic movement relative to the frame 10. The second blocking member 72 is arranged on the sixth telescopic portion 711 and the two move synchronously, so that the second blocking member 72 has a second release position 72a and a second blocking position 72b relative to the frame 10. The sixth cylinder 71 can be electrically connected to the third cylinder 31 or the suction cup component 43, or the sixth cylinder 71 is controlled by an independent signal of the controller. When the box body 301 and the box cover 302 at the first position 10a and the second position 10b are performing a closing operation, the sixth cylinder 71 drives the second blocking member 72 to switch to the second blocking position 72b to block the next box body 301 that is about to enter the first position 10a. When the box body 301 and the box cover 302 at the first position 10a and the second position 10b complete the closing operation and exit the frame 10, the sixth cylinder 71 drives the second blocking member 72 to switch to the second release position 72a, so that the blocked box body 301 can move to the first position 10a under the conveying action of the conveyor belt.

[0044] In the above embodiment, the second stopper assembly 70 is a cylinder that moves linearly to allow the second stopper 72 to switch between the second stopper position 72b and the second release position 72a. In other examples, the second stopper assembly 70 can also be a motor that drives the second stopper 72 to rotate relative to the frame 10 to achieve the switching of the second stopper 72 between the second stopper position 72b and the second release position 72a.

[0045] In some embodiments, see Figure 4 The packaging box cover closing device 100 further includes a first guide plate 81 and a second guide plate 82, which are respectively connected to the frame 10 and arranged opposite to each other, and a feeding channel 83 is formed between the first guide plate 81 and the second guide plate 82, and the box body 301 and the box cover 302 move in the feeding channel 83. As an example, the first guide plate 81 is arranged on the first side portion 13 of the frame 10, and the second guide plate 82 is arranged on the second side portion 14 of the frame 10. When the first direction X is parallel to the conveying direction M of the conveyor belt, under the guiding action of the first guide plate 81 and the second guide plate 82, the box body 301 and the box cover 302 enter the feeding channel 83 in a front-to-back order from the entrance end 11 of the frame 10. When the first direction X is perpendicular to the conveying direction M of the conveyor belt, under the guidance of the first guide plate 81 and the second guide plate 82 , the box body 301 and the box cover 302 are arranged side by side in the feeding channel 83 and enter from the inlet end 11 of the frame 10 at the same time.

[0046] In some embodiments, see Figure 1 and Figure 4 , the packaging box closing device 100 also includes a second detection component 90, which is arranged on the frame 10 and corresponds to the second position 10b. The second detection component 90 is configured to detect the scanning area K on the outer surface of the box cover 302 located at the second position 10b to determine the forward and reverse directions of the box cover 302. When there is a direction requirement when the box cover 302 is closed with the box body 301, for example, in the subsequent process, it is necessary to label or spray code on a specific area on the surface of the box cover 302, then it is necessary to identify whether the position of the box cover 302 is correct to avoid the box cover 302 and the box body 301 from being assembled incorrectly. For example, the forward direction of the box cover 302 is set as the box cover 302 has and only one direction is the correct direction for closing with the box body 301, then the remaining directions of the box cover 302 are all reverse directions.

[0047] As an example, see Figure 4 The second detection component 90 includes a third sensor 91, which is disposed on the frame 10 and corresponds to the second position 10b. When the third sensor 91 can identify the scanning area K with a preset mark on the box cover 302, it is determined that the box cover 302 is in the forward position, otherwise it is determined that the box cover 302 is in the reverse position. When the box cover 302 is in the forward position, the box cover 302 and the box body 301 are closed as described in the above embodiment. When the box cover 302 is in the reverse position, the box body 301 and the box cover 302 are directly released, so that the worker can identify the abnormal closing of the box, thereby readjusting the position of the box cover 302.

[0048] In some embodiments, the second detection assembly 90 further includes a first switch (not shown), which is disposed on the frame 10 and electrically connected to the third sensor 91. The first switch is configured to control whether the third sensor 91 is in a working state. When the box cover 302 and the box body 301 have a specific covering direction requirement, the first switch can be controlled so that the third sensor 91 is in a working state, and when the box cover 302 and the box body 301 do not have a specific covering direction requirement, the first switch can be controlled so that the third sensor 91 is in a stopped working state.

[0049] In some embodiments, the packaging box capping device 100 further includes a rotating assembly (not shown), which is connected to the second cylinder 422 and the suction cup component 43 respectively, and the rotating assembly is configured to drive the suction cup component 43 to rotate relative to the frame 10. When the third sensor 91 recognizes that the box cover 302 located at the second position 10b is in the reverse direction, the box body 301 and the box cover 302 are still covered. The difference is that after the suction cup component 43 sucks the box cover 302, the rotating assembly drives the suction cup component 43 to rotate, thereby rotating the angle of the box cover 302, for example, the rotating assembly rotates 90 degrees, 180 degrees, 270 degrees or other angles relative to the frame 10, so that the box cover 302 can be correctly covered and connected with the box body 301. By adding a rotating assembly, the degree of automated operation of the packaging box capping device 100 can be further increased, manual intervention can be further reduced, and the level of intelligence can be provided.

[0050] The packaging box covering device 100 of the embodiment of the present application includes a frame 10, a first detection component 20, a first limit component 30 and a suction component 40. The frame 10 has a first position 10a and a second position 10b inside; the first detection component 20 is arranged on the frame 10, and the first detection component 20 is configured to detect whether the box body 301 of the packaging box passes through the first position 10a, and whether the box cover 302 of the packaging box reaches the second position 10b; the first limit component 30 is arranged on the frame 10, and the first limit component 30 is configured to detect whether the box body 301 passes through the first position 10a, and whether the box cover 302 of the packaging box reaches the second position 10b. The suction assembly 40 includes a first component 41, a second component 42 and a suction cup component 43. The first component 41 is arranged on the frame 10, the second component 42 is arranged on the first component 41, the first component 41 drives the second component 42 to reciprocate along the first direction X, the suction cup component 43 is arranged on the second component 42, and the second component 42 drives the suction cup component 43 to reciprocate along the second direction Y. The first direction X and the second direction Y are perpendicular. The suction cup component 43 is configured so that when the box cover 302 reaches the second position 10b, the suction cup component 43 absorbs the box cover 302 and moves to cover the box body 301. Through the above structure, the packaging box covering device 100 can mechanically cover the box body 301 with the box cover 302, reduce manual assembly, and effectively improve the assembly efficiency of the production line.
