[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0027] Please see Figure 1This application provides an embodiment of an assembly line operation system 1000. The assembly line operation system 1000 includes a conveyor belt device 200 and a packaging box closing device 100. The packaging box closing device 100 is disposed on the conveyor belt device 200. The conveyor belt device 200 is configured to transport the box body 301 and the box lid 302 of the packaging box into the interior of the packaging box closing device 100 in the conveying direction M. The packaging box closing device 100 closes the box lid 302 with the box body 301 so that the conveyor belt device 200 can continue to transport the assembled packaging box to the next station.
[0028] For the aforementioned packaging box closing device 100, please refer to... Figure 1 The packaging box closing device 100 includes a frame 10, a first detection component 20, a first limiting component 30, and a suction component 40. The frame 10 has a first position 10a and a second position 10b, which are opposite to each other. The first detection component 20 is disposed on the frame 10 and is configured to detect whether the box body 301 has passed the first position 10a and whether the box lid 302 has reached the second position 10b. The first limiting component 30 is disposed on the frame 10 and is configured to move to block the box body 301 when it passes the first position 10a, so that the box body 301 remains stationary relative to the frame 10. The suction assembly 40 is mounted on the frame 10. When the first limiting assembly 30 blocks the box body 301 at the first position 10a, the corresponding lid 302 is blocked by the box body 301 at the second position 10b. The suction assembly is then configured to pick up the lid 302 when it reaches the second position 10b and move it to fit together with the box body 301 at the first position 10a. This achieves mechanized assembly of the box body 301 and the lid 302, eliminating manual assembly and effectively improving production efficiency.
[0029] In some embodiments, please refer to Figure 1 and Figure 2 The frame 10 is a frame structure formed by splicing several tubes. The frame 10 has an inlet end 11 and an outlet end 12 in the direction of conveying the packaging boxes by the conveyor belt device 200. The box body 301 and the lid 302 of the packaging box enter the interior of the frame 10 from the inlet end 11. After assembly, the 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 conveyor belt, the box body 301 is located in front of the lid 302.
[0030] For the above-mentioned suction component 40, please refer to Figure 2 and Figure 3The suction assembly 40 includes a first component 41, a second component 42, and a suction cup component 43. 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. The first direction X and the second direction Y are substantially perpendicular. In some embodiments, the first direction X may be parallel to the conveying direction M of the conveyor belt device 200 for transporting the packaging boxes, and the second direction Y may be perpendicular to the surface of the drive belt in the conveyor belt device 200. Of course, in other embodiments, the first direction X may be perpendicular to the conveying direction M of the conveyor belt device 200 for transporting the packaging boxes, and the second direction Y may be perpendicular to the surface of the drive belt in the conveyor belt device 200.
[0031] The following description uses an example where the first direction X is parallel to the conveying direction M of the conveyor belt device 200 for transporting packaging boxes. Please refer to [link to example description]. 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, so as to fix the first cylinder 412 to the frame 10. The first telescopic part 4121 in the first cylinder 412 reciprocates and extends along the first direction X. Please refer to the following: 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 part 4121 of the first cylinder 412 and the second cylinder 422, respectively, to fix the second cylinder 422 onto the first telescopic part 4121 and to reciprocate synchronously with the first telescopic part 4121 in the first direction X. The second telescopic part 4221 in the second cylinder 422 reciprocates and extends 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 part 4221 of the second cylinder 422 and the suction cup 432, respectively, to fix the suction cup 432 onto the second telescopic part 4221, so that the suction cup 432 and the second telescopic part 4221 reciprocate and extend synchronously in the second direction Y. The suction cup 432 is connected to an external suction source so that when the suction cup 432 comes into contact with the lid 302, it can generate negative pressure to suck up the lid 302.
[0032] It is worth noting that in the above embodiment, the suction cup 432 is driven by a cylinder as a power source. In other embodiments, the movement can also be driven by a guide rail and pulley, or by a rack and pinion and a motor, etc., to satisfy the need to drive the suction cup 432 to move in the first direction X and the second direction Y.
[0033] In some embodiments, please continue reading Figure 3The second component 42 also includes a first guide 423, which is connected to the frame 10 and the second fixing component 421 respectively. The first guide 423 can move relative to the frame 10 along a first direction X. As an example, the first guide 423 is sleeved on the tube body of the frame 10. The first guide 423 is used to guide the first telescopic part 4121 in the first cylinder 412. At the same time, the first guide 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 423 has a pulling force on the second cylinder 422 and the suction cup component 43, thereby avoiding violent shaking when the first telescopic part 4121 of the first cylinder 412 moves, which would reduce the suction accuracy and stability of the suction cup component 43.
[0034] In some embodiments, please refer to Figure 3 The suction cup component 43 further includes a first air tube 433, a second air tube 434, and a first elastic element 435. The first air tube 433 is disposed on the third fixing member 431. The second air tube 434 is sleeved and connected to the first air tube 433 and can move axially and telescopically relative to the first air tube 433. The suction cup 432 is disposed at the end of the second air tube 434, and the first air tube 433, the second air tube 434, and the suction cup 432 are in gas communication. The first elastic element 435 is sleeved on the outside of the first air tube 433 and the second air tube 434, and is connected to the second air tube 434 and the third fixing member 431, respectively. Alternatively, in other examples, the first elastic element 435 is connected to the suction cup 432 and the first air tube 433, respectively. This structure allows for telescopic movement between the first air tube 433 and the second air tube 434. This enables the second telescopic part 4221 of the second cylinder 422 to buffer the suction cup 432 as it moves along the second direction Y and comes into contact with the lid 302, preventing the suction cup 432 from directly impacting the surface of the lid 302. It also allows for adjustment of the suction cup 432's descent height, overcoming the problem of the suction cup 432 failing to pick up the lid 302 due to dimensional errors. The first elastic element 435 serves to buffer the movement between the first air tube 433 and the second air tube 434 and provides elastic force for their repositioning movement.
[0035] For the aforementioned first limiting component 30, please refer to Figure 2 and Figure 3The first limiting component 30 is disposed near the outlet end 12 of the frame 10. The first limiting component 30 includes a third cylinder 31 and a first blocking member 32. The third cylinder 31 is disposed at the outlet end 12 of the frame 10. The third telescopic portion 311 of the third cylinder 31 extends and retracts along the second direction Y. The first blocking member 32 is disposed on the third telescopic portion 311 and extends and retracts 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 [link / reference]. 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 component 30 under the conveying action of the conveyor belt. 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 work together to drive the suction cup 432 to pick up the box cover 302 at the second position 10b and close it with the box body 301 at the first position 10a.
[0036] In the above embodiment, the first limiting component 30 switches the first blocking member 32 between the first blocking position 32b and the first releasing position 32a by the linear extension and retraction of a cylinder. In other examples, the first limiting component 30 can also switch the first blocking member 32 between the first blocking position 32b and the first releasing position 32a by driving the first blocking member 32 to rotate relative to the frame 10 by a motor or the like.
[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 mounted 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 301 at the first position 10a. If there is, it sends a blocking signal to the third cylinder 31 to drive the first limiting component to move to the first blocking position 32b. The second sensor 22 is mounted on the frame 10 and corresponds to the second position 10b. The second sensor 22 is electrically connected to the suction assembly 40. The second sensor 22 is used to detect whether there is a lid 302 at the second position 10b. If there is, it sends a closing signal to the suction assembly 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 pick up the lid 302 at the second position 10b and place it above the box body 301 at the first position 10a. Under the gravity of the lid 302 and / or the driving action of the second cylinder 422, the lid 302 and the box body 301 are closed and connected, completing 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 lid 302 continue to move together.
[0038] In some embodiments, please refer to 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 a first position 10a. The first pushing assembly 50 is configured to position and fix the box body 301 located at the first position 10a. The second pushing assembly 60 is disposed on the frame 10 and corresponds to a second position 10b. The second pushing assembly 60 is configured to position and fix the box lid 302 located at the second position 10b. The center of the positioned box body 301 and the center of the positioned box lid 302 are collinearly distributed along the first direction X. By setting the first push component 50 and the second push component 60, the box body 301 and the box cover 302 can be relatively fixed, and their centers are collinearly distributed in the first direction X. This allows the suction cup component 43 to pick up the box cover 302 and move it above the box body 301, so that the two can be smoothly closed and connected, improving the accuracy of the closing connection and reducing the probability that the box cover 302 cannot be fully closed and connected with the box body 301 or gets stuck during the closing process.
[0039] As an example, please refer to Figure 2 The frame 10 has opposing first side portions 13 and second side portions 14. The first pushing assembly 50 includes a fourth cylinder 51 and a first positioning member 52. The fourth cylinder 51 is disposed on one of the first side portions 13 and the second side portion 14, and the first positioning member 52 is disposed on the other of the first side portions 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 pushing assembly 60 includes a fifth cylinder 61 and a second positioning member 62. The fifth cylinder 61 is disposed on one of the first side portions 13 and the second side portion 14, and the second positioning member 62 is disposed on the other of the first side portions 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 a box 301 at the first position 10a and the first blocking member 32 blocks the box 301, the fourth telescopic part 511 extends to abut the box 301 against the first positioning member 52, thereby positioning and fixing the box 301. When the second sensor 22 detects a lid 302 at the second position 10b, the fifth telescopic part 611 extends to abut the lid 302 against the second positioning member 62, thereby positioning and fixing the lid 302. The center of the positioned box 301 and the center of the positioned lid 302 are collinear 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 pick up the lid 302 and move it above the box 301, thereby achieving a closed connection between the two.
[0041] In some embodiments, a buffer layer may be provided on the surfaces of the fourth telescopic portion 511 and the first positioning member 52 that contact the box body 301 to avoid direct impact on the surface of the box body 301 and scratching it. Similarly, a buffer layer may be provided on the surfaces of the fifth telescopic portion 611 and the second positioning member 62 that contact the lid 302 to avoid direct impact on the surface of the lid 302 and scratching it.
[0042] In some embodiments, please refer to Figure 1 The packaging box closing device 100 also includes a second limiting component 70, which is disposed on the frame 10. Along the direction of movement of the packaging box, the first pushing component 50 and the second limiting component 70 are respectively disposed on both sides of the second pushing component 60. The second limiting component 70 is configured to block the next box 301 from entering the first position 10a when the first position 10a has a box 301. Since the presence of a box 301 at the first position 10a indicates that the closing operation of the box 301 and the lid 302 is in progress at the first position 10a and the second position 10b, in order to prevent the next box 301 from entering and causing interference, the second limiting component 70 can be disposed on the side of the second pushing component 60 near the entrance end 11 of the frame 10 to prevent the next box 301 from entering.
[0043] As an example, please refer to Figure 4The second limiting component 70 includes a sixth cylinder 71 and a second blocking member 72. The sixth cylinder 71 is disposed on the first side 13 or the second side 14 or other areas of the frame 10. The sixth telescopic part 711 in the sixth cylinder 71 can telescopically move relative to the frame 10. The second blocking member 72 is disposed on the sixth telescopic part 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 can be controlled by an independent signal from the controller. When the box 301 at the first position 10a and the box cover 302 are in the process of closing, the sixth cylinder 71 drives the second blocking member 72 to switch to the second blocking position 72b to block the next box 301 that is about to enter the first position 10a. When the box 301 at the first position 10a and the box cover 302 have completed the closing operation and exited 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 301 can move to the first position 10a under the conveyor belt.
[0044] In the above embodiment, the second limiting component 70 switches the second blocking member 72 between the second blocking position 72b and the second releasing position 72a by the linear extension and retraction of a cylinder. In other examples, the second limiting component 70 can also switch the second blocking member 72 between the second blocking position 72b and the second releasing position 72a by driving the second blocking member 72 to rotate relative to the frame 10 via a motor or the like.
[0045] In some embodiments, please refer to Figure 4 The packaging box closing device 100 also includes a first guide plate 81 and a second guide plate 82. The first guide plate 81 and the second guide plate 82 are respectively connected to the frame 10 and arranged opposite to each other. 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 provided on the first side 13 of the frame 10, and the second guide plate 82 is provided on the second side 14 of the frame 10. Wherein, when the first direction X is parallel 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 enter the feeding channel 83 in a front-to-back sequence 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 entrance end 11 of the frame 10 at the same time.
[0046] In some embodiments, please refer to Figure 1 and Figure 4 The packaging box closing device 100 also includes a second detection component 90, which is mounted 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 lid 302 located at the second position 10b to determine the orientation of the box lid 302. When there is a directional requirement when the box lid 302 closes with the box body 301, such as when a label or code needs to be affixed to a specific area on the surface of the box lid 302 in subsequent processes, it is necessary to identify whether the position of the box lid 302 is correct to avoid incorrect assembly of the box lid 302 and the box body 301. For example, if the orientation of the box lid 302 is defined as the correct orientation for closing with the box body 301 in one and only one direction, then all other orientations of the box lid 302 are considered reverse orientations.
[0047] As an example, please refer to Figure 4 The second detection component 90 includes a third sensor 91, which is mounted on the frame 10 and corresponds to the second position 10b. When the third sensor 91 can identify the barcode scanning area K with a preset mark on the lid 302, it determines that the lid 302 is in the forward position; otherwise, it determines that the lid 302 is in the reverse position. When the lid 302 is in the forward position, the lid 302 and the box body 301 are closed as described in the above embodiment. When the lid 302 is in the reverse position, the box body 301 and the lid 302 are released directly so that workers can identify the abnormal box closure and readjust the position of the lid 302.
[0048] In some embodiments, the second detection component 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 an active state. When there is a specific closing orientation requirement between the lid 302 and the body 301, the first switch can be controlled to activate the third sensor 91; when there is no specific closing orientation requirement between the lid 302 and the body 301, the first switch can be controlled to deactivate the third sensor 91.
[0049] In some embodiments, the packaging box closing device 100 further includes a rotating assembly (not shown), which is connected to the second cylinder 422 and the suction cup component 43 respectively. The rotating assembly is configured to drive the suction cup component 43 to rotate relative to the frame 10. When the third sensor 91 detects that the lid 302 at the second position 10b is in the reverse direction, the closing operation between the box body 301 and the lid 302 is still performed. The difference is that after the suction cup component 43 picks up the lid 302, the rotating assembly drives the suction cup component 43 to rotate, thereby rotating the angle of the lid 302. For example, the rotating assembly rotates 90 degrees, 180 degrees, 270 degrees, or other angles relative to the frame 10, so that the lid 302 can be correctly closed and connected to the box body 301. By adding the rotating assembly, the degree of automation of the packaging box closing device 100 can be further increased, further reducing manual intervention and providing a higher level of intelligence.
[0050] The packaging box closing device 100 of this application embodiment includes a frame 10, a first detection component 20, a first limiting 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 disposed on the frame 10 and is configured to detect whether the box body 301 of the packaging box has passed the first position 10a and whether the box lid 302 of the packaging box has reached the second position 10b. The first limiting component 30 is disposed on the frame 10 and is configured to move the box body 301 when it passes the first position 10a. The assembly 40 includes a first component 41, a second component 42, and a suction cup component 43. The first component 41 is mounted on the frame 10, and the second component 42 is mounted on the first component 41. The first component 41 drives the second component 42 to reciprocate along a first direction X. The suction cup component 43 is mounted on the second component 42, and the second component 42 drives the suction cup component 43 to reciprocate along a second direction Y. The first direction X and the second direction Y are perpendicular. The suction cup component 43 is configured to pick up the lid 302 and move it to close the lid 302 with the box body 301 when the lid 302 reaches the second position 10b. With the above structure, the packaging box closing device 100 can mechanically close the box body 301 with the lid 302, reducing manual assembly and effectively improving the assembly efficiency of the production line.
