Description

Technical Field

[0001] This application relates to the field of conveying technology, and in particular to a conveying system. Background Technology

[0002] Conveying systems are crucial equipment in production lines, and their conveying speed directly impacts the production cycle. Currently, ultra-high-speed conveying systems exist, offering significantly improved material handling efficiency and enabling production lines to complete more tasks in a shorter time, thus shortening the production cycle. These systems are widely used in various manufacturing enterprises. However, when these ultra-high-speed conveying systems are integrated with elevators and traverse machines, a transition roller bed is required to switch the drive mode to achieve the lifting and lowering of the conveyor trolley.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0055] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0056] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0059] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0060] Please see Figure 1 , Figure 1A schematic diagram of the conveying system in one embodiment of this application is shown. The conveying system provided in one embodiment of this application includes a conveying carrier 1, a conveying line 2, and a drive docking mechanism 3. The conveying line 2 is used to carry the conveying carrier 1. The conveying line 2 includes a conveying component and at least one working station 22. The working station 22 is arranged at one end of the conveying component along the conveying direction of the conveying component. The drive docking mechanism 3 is used to drive the conveying carrier 1 to reciprocate between the conveying component and the working station 22.

[0061] Please refer to the following: Figure 3 , Figure 5-6 as well as Figure 8 In some embodiments, the conveying carrier 1 is provided with a first connecting component 12; the driving docking mechanism 3 includes a first driving component 31, a first auxiliary component 32, and a docking component 33. The first driving component 31 is disposed on the conveying component; the first auxiliary component 32 includes a first auxiliary structure 321 and a second auxiliary structure 322. The first auxiliary structure 321 is disposed at a first position on the conveying component, and the second auxiliary structure 322 is disposed at a second position on the conveying component. The first position is located at one end of the conveying component near the working station 22, and the second position is located at one end of the conveying component away from the working station 22; the docking component 33 is slidably disposed on the conveying component and connected to the first driving component 31. The first driving component 31 is used to drive the docking component 33 to reciprocate between the first position and the second position; the docking component 33 cooperates with the first auxiliary structure 321 at the first position to connect or separate from the first connecting component 12 of the conveying carrier 1, and the docking component 33 cooperates with the second auxiliary structure 322 at the second position to connect or separate from the first connecting component 12, so that the conveying carrier 1 reciprocates between the conveying component and the working station 22.

[0062] It is understandable that when the conveying carrier 1 needs to move from the working station 22 to the conveying assembly, the conveying carrier 1 is located at the working station 22. The docking component 33 moves to the first position under the drive of the first driving component 31 and cooperates with the first auxiliary structure 321 at the first position, so that the docking component 33 is connected to the first connecting component 12. At this time, the docking component 33 is connected to the conveying carrier 1. The docking component 33 moves to the second position under the drive of the first driving component 31, and the conveying carrier 1 also moves to the conveying assembly. The docking component 33 moves to the second position and cooperates with the second auxiliary structure 322 at the second position, so that the docking component 33 and the first connecting component 12 are separated. At this time, the docking component 33 is separated from the conveying carrier 1, and the conveying carrier 1 moves from the working station 22 to the conveying assembly. When the conveying carrier 1 needs to move from the conveying assembly to the working station 22, the conveying carrier 1 is located on the conveying assembly. The docking assembly 33 moves to the second position under the drive of the first drive assembly 31, and cooperates with the second auxiliary structure 322 at the second position, so that the docking assembly 33 connects with the first connecting assembly 12. At this time, the docking assembly 33 is connected to the conveying carrier 1. The docking assembly 33 moves to the first position under the drive of the first drive assembly 31, and the conveying carrier 1 also moves to the working station 22. The docking assembly 33 moves to the first position and cooperates with the first auxiliary structure 321 at the first position, so that the docking assembly 33 and the first connecting assembly 12 separate. At this time, the docking assembly 33 separates from the conveying carrier 1, and the conveying carrier 1 moves from the conveying assembly to the working station 22. The conveying system provided by this application does not require the addition of a transition roller bed when docking at the working station 22, making the overall structure of the conveying system more compact, occupying less space, and saving space.

[0077] In this embodiment, the second mating element 32236 has the same structure as the first mating element 32132, and will not be described in detail here.

[0078] Please refer to the following: Figures 20 to 23 , Figures 20 to 23 This is a schematic diagram illustrating the process of the docking assembly 33 moving to the first position and connecting with the conveying carrier 1 in cooperation with the first auxiliary structure 321. It can be understood that, driven by the first driving assembly 31, the docking assembly 33 moves towards the first position. The first roller 3346 of the first docking structure 334 contacts the first inclined surface 1221 of the limiting member 122. As the docking assembly 33 moves, the first roller 3346 moves along the first inclined surface 1221. At this time, the first insertion member 3342 is subjected to the downward force of the first inclined surface 1221. Under the guidance of the guide member 3343, the first connecting member 3345 and the first spring guide rod 33441 move downward. The first spring cover 33443, which is provided on the first spring guide rod 33441, compresses the first spring 33442 when it moves downward. As the docking assembly 33 continues to move toward the first position, the first roller 3346 continues to move along the first inclined surface 1221 of the limiting member 122 until the first roller 3346 moves below the first plane 1222 of the limiting member 122.

[0079] As the docking assembly 33 moves toward the first position, the second roller 3347 of the first docking structure 334 contacts the first mating element 32132 of the first auxiliary component 3213. As the docking assembly 33 continues to move toward the first position, the second roller 3347 moves along the inclined section of the first mating element 32132. At this time, the first insertion member 3342 continues to move downward, and the first spring 33442 continues to be compressed until the docking assembly 33 moves to the first position.

[0080] When the docking assembly 33 moves to the first position, the first plug-in member 3342 is located below the limiting groove 124, and the second roller 3347 abuts against the plane section below the first mating element 32132. When the output end of the first telescopic member 3212 extends vertically, the first auxiliary member 3213 extends vertically as well. At this time, the second roller 3347 is disengaged from the obstruction of the first mating element 32132. Under the action of the first spring 33442, the first connecting member 3345 moves upward, and the first plug-in member 3342 also extends, so that the first plug-in member 3342 and the first roller 3346 are inserted into the limiting groove 124 of the first connecting assembly 12. After the first auxiliary member 3213 is fully extended, there is a gap between it and the second roller 3347. At this time, the docking assembly 33 and the conveying carrier 1 are connected.

[0081] When the docking assembly 33 needs to be separated from the conveying carrier 1, the output end of the first telescopic member 3212 retracts vertically, and the first auxiliary member 3213 retracts vertically accordingly. At this time, the planar section of the first mating element 32132 contacts the second roller 3347. The second roller 3347 is pressed down by the first mating element 32132, causing the first connecting member 3345 to move downward. The first plug-in member 3342 and the first spring guide rod 33441 also move downward. The first spring cover 33443 compresses the first spring 33442. The first plug-in member 3342 and the first roller 3346 exit the limiting groove 124 of the first connecting assembly 12. At this time, the docking assembly 33 is separated from the conveying carrier 1. When the docking assembly 33 moves away from the first position, the second roller 3347 moves along the inclined section of the first mating element 32132 until the second roller 3347 disengages from the first mating element 32132; the first roller 3346 on the first plug 3342 moves along the first inclined surface 1221 of the limiting member 122 until the first roller 3346 disengages from the limiting member 122.

[0082] In some embodiments, the conveying assembly includes at least two conveying stations 21, which are arranged along the conveying direction; the conveying system also includes at least one drive connection mechanism 4, which is used to drive the conveying carrier 1 to reciprocate between two adjacent conveying stations 21.

[0083] Please refer to the following: Figure 9 and Figure 10 In some embodiments, the drive connection mechanism 4 includes a second drive component (not shown), a second auxiliary component (not shown), and a second connection component 43. The second drive component is disposed on the conveying component. The second auxiliary component includes two third auxiliary structures, which are respectively disposed at a third position and a fourth position on the conveying component. The third position is located in the middle of one conveying station 21, and the fourth position is located in the middle of another adjacent conveying station 21. The second connection component 43 is slidably disposed on the conveying component and connected to the second drive component. The second drive component is used to drive the second connection component 43 to reciprocate between the third position and the fourth position. The second connection component 43 cooperates with the third auxiliary structure in the third position to connect or separate from the first connection component 12 of the conveying carrier 1. The second connection component 43 cooperates with the third auxiliary structure in the fourth position to connect or separate from the first connection component 12. The conveying carrier 1 can reciprocate between two adjacent conveying stations 21 under the drive of the drive connection mechanism 4.

[0084] It is understandable that when the conveying carrier 1 needs to move from one conveying station 21 to another adjacent conveying station 21, the conveying carrier 1 is located at one conveying station 21. The second connecting component 43 moves to the third position under the drive of the second driving component and cooperates with the third auxiliary structure at the third position, so that the second connecting component 43 is connected to the first connecting component 12. At this time, the second connecting component 43 is connected to the conveying carrier 1. The second connecting component 43 moves to the fourth position under the drive of the second driving component, and the conveying carrier 1 also moves to another adjacent conveying station 21. The second connecting component 43 moves to the fourth position and cooperates with the third auxiliary structure at the fourth position, so that the second connecting component 43 and the first connecting component 12 are separated. At this time, the second connecting component 43 is separated from the conveying carrier 1, and the conveying carrier 1 moves from one conveying station 21 to another adjacent conveying station 21. When the conveying carrier 1 needs to return from the adjacent conveying station 21 to its original conveying station 21, the conveying carrier 1 is located at the adjacent conveying station 21. The second connecting component 43 moves to the fourth position under the drive of the second driving component and cooperates with the third auxiliary structure at the fourth position, so that the second connecting component 43 is connected to the first connecting component 12. At this time, the second connecting component 43 is connected to the conveying carrier 1. The second connecting component 43 moves to the third position under the drive of the second driving component, and the conveying carrier 1 also moves back to its original conveying station 21. The second connecting component 43 moves to the third position and cooperates with the third auxiliary structure at the third position, so that the second connecting component 43 and the first connecting component 12 are separated. At this time, the second connecting component 43 is separated from the conveying carrier 1, and the conveying carrier 1 moves from the adjacent conveying station 21 back to its original conveying station 21.

[0085] In this embodiment, the second driving component has the same structure as the first driving component 31, and the third auxiliary structure has the same structure as the second auxiliary structure 322, which will not be described in detail here.

[0086] In some embodiments, the second connecting component 43 includes a second slide 431 and a second docking structure 434. The second slide 431 is slidably disposed on the conveying component and connected to the second driving component. The second slide 431 is movable along the conveying direction under the drive of the second driving component. The second docking structure 434 is disposed in the middle of the second slide 431.

[0087] In some embodiments, a second mounting hole (not shown) is provided in the middle of the second slide 431. The second mating structure 434 includes a second mounting base 4341, a second plug-in member 4342, a second reset member 4344, a second connector 4345, a third roller 4346, a fourth roller 4347, and a third cover plate 4348. The second mounting base 4341 is disposed in the second mounting hole, and a portion of the second mounting base 4341 protrudes from the upper surface of the second slide 431, and a portion of the second mounting base 4346 protrudes from the lower surface of the second slide 431. The second mounting base 4341 has a plurality of second through holes, and the second plug-in member 4342 and the second... The reset members 4344 are respectively inserted into the second through holes, and a portion of the second plug-in members 4342 protrudes from the upper surface of the second slide table 431; the third roller 4346 is rotatably disposed on the second plug-in members 4342 and located above the upper surface of the second slide table 431; the second connector 4345 is disposed at the bottom of the second mounting base 4341 and is connected to the second plug-in members 4342 and the second reset members 4344; the second connector 4345 has a second protrusion 43451 on the side away from the second slide table 431, and the fourth roller 4347 is rotatably disposed on the second protrusion 43451; the third cover plate 4348 is disposed on the top surface of the second mounting base 4341.

[0088] In some embodiments, the second reset member 4344 includes a second spring guide rod 43441, a second spring 43442, and a second spring cover 43443. The second spring guide rod 43441 is inserted into the second through hole and connected to the second connector 4345. The second spring 43442 is sleeved on the second spring guide rod 43441. The second spring cover 43443 is disposed at the end of the second spring guide rod 43441 away from the second connector 4345 and compresses the second spring 43442 in the second through hole.

[0089] In some embodiments, the second connecting assembly 43 further includes a fourth guide structure 432, a second adjustment structure 433, a second cleaning structure 435, and a second anti-collision structure 436. The fourth guide structure 432 guides the second connecting assembly 43 to move along the conveying direction on the conveying assembly. The second adjustment structure 433 adjusts the tension of the synchronous belt 315 connected to the second slide table 431. The second cleaning structure 435 scrapes away dust or debris from the conveying assembly. The second anti-collision structure 436 prevents the second connecting assembly 43 from being damaged when it collides with other structures of the conveying assembly during movement, thereby improving the safety of the conveying system. In this embodiment, the fourth guide structure 432 has the same structure as the third guide structure 332, the second adjustment structure 433 has the same structure as the first adjustment structure 333, the second cleaning structure 435 has the same structure as the first cleaning structure 335, and the second anti-collision structure 436 has the same structure as the first anti-collision structure 336, which will not be described in detail here.

[0090] It is understood that the second connecting component 43 has a similar structure to the docking component 33, and the connection process between the second connecting component 43 and the conveying carrier 1 is similar to the connection process between the docking component 33 and the conveying carrier 1. Through the guiding effect of the third roller 4346 of the second docking structure 434 and the first inclined surface 1221 of the limiting member 122, the cooperation effect of the third auxiliary structure and the second connecting component 43, and the reset effect of the second reset member 4344, the second insertion member 4342 and the third roller 4346 are inserted into the limiting groove 124 of the first connecting component 12, thereby realizing the connection between the second connecting component 43 and the conveying carrier 1.

[0091] The process of the second connecting component 43 disengaging from the conveying carrier 1 is similar to the process of the docking component 33 disengaging from the conveying carrier 1. By retracting the second telescopic component 3222, the second plug-in component 4342 and the third roller 4346 exit the limiting groove 124 of the first connecting component 12, thereby achieving disengagement from the conveying carrier 1.

[0092] Please refer to the following: Figure 11 and Figure 12 In some embodiments, both the working station 22 and the conveying station 21 are constructed by splicing together at least one first base 23 and at least one second base 24. The first base 23 includes a first frame 231, two first guide rails 232, multiple first guide structures 233, and multiple first support structures 234. The two first guide rails 232 are arranged opposite each other and located on both sides of the top of the first frame 231. The multiple first guide structures 233 are disposed on the upper part of the two outer side walls of the first frame 231 and are arranged sequentially at intervals along the conveying direction to support the conveying carrier 1. When the conveying carrier 1 is located on the first base 23, the first rod 111 is slidably connected to the multiple first guide structures 233 to reduce the frictional force of the conveying carrier 1 moving on the first frame 231, making the movement of the conveying carrier 1 smoother, reducing running resistance, and preventing the conveying carrier 1 from deviating from the conveying direction. The multiple first support structures 234 are disposed on the lower part of the two outer side walls of the first frame 231 to support the first frame 231. The second base 24 includes a second frame 241, two second guide rails 242, multiple second guide structures 243, and multiple second support structures 244. The second frame 241 and the first frame 231 have different lengths in the conveying direction. The two second guide rails 242 are arranged opposite each other and located on both sides of the top of the second frame 241. Multiple second guide structures 243 are arranged on the upper part of the two outer side walls of the second frame 241 and are arranged sequentially at intervals along the conveying direction to support the conveying carrier 1. When the conveying carrier 1 is located on the second base 24, the first rod 111 is slidably connected to the multiple second guide structures 243. Multiple second support structures 244 are arranged on the lower part of the two outer side walls of the second frame 241 to support the second frame 241.

[0093] In some embodiments, the first guide structure 233 and the second guide structure 243 are both first conveying guide wheels. The first conveying guide wheels are vertically arranged relative to the working position 22 and are used to connect with the rollers of the conveying carrier 1 and guide the conveying carrier 1 to move along the conveying direction.

[0094] In some embodiments, the equipment on the workstation 22 includes, but is not limited to, a traverse machine, a lift, or similar equipment. In some embodiments, the first frame 231 has a length of 2 meters in the conveying direction, the second frame 241 has a length of 1.5 meters in the conveying direction, and the first base 23 and the second base 24 can be spliced ​​together to form a workstation spacing of more than 3 meters. By modularizing the first base 23 and the second base 24, multiple first bases 23 and second bases 24 can be used to splice together to form workstations 22 and conveying stations 21 with different workstation spacings, in order to adapt to different production needs or equipment configurations. This facilitates the assembly and adjustment of the workstations 22 and the conveying stations 21, reducing assembly time. At the same time, it also reduces non-standard parts, lowers production costs, and makes the structure of the workstations 22 and the conveying stations 21 more compact, reducing the floor space and saving space.

Each conveying station 21 and working station 22 is provided with at least four YZ-direction positioning units 63. Each YZ-direction positioning unit 63 includes a second mounting frame 631, a roller seat 632, a Y-direction positioning roller 633, and a first Z-direction positioning roller 634. The second mounting frame 631 is disposed on the two outer side walls of the conveying station 21 and the working station 22. The roller seat 632 is disposed on the second mounting frame 631 and has a first roller mounting groove 6321. The Y-direction positioning roller 633 is rotatably disposed on the roller seat 632 and is horizontally disposed relative to the roller seat 632. The first Z-direction positioning roller 634 is rotatably disposed on the first roller mounting groove 6321, and a portion of the first Z-direction positioning roller 634 protrudes from the upper surface of the roller seat 632. The first Z-direction positioning roller 634 is vertically disposed relative to the roller seat 632. The Y-direction positioning roller 633 and the first Z-direction positioning roller 634 are perpendicular to each other. In some embodiments, when multiple YZ-direction positioning units 63 are provided on the same side of the conveyor line 2, the multiple YZ-direction positioning units 63 are staggered along the conveying direction.

[0100] Please refer to the following: Figure 16 In some embodiments, the Z-axis positioning assembly 7 includes at least two second Z-axis positioning members 71 and a plurality of Z-axis positioning units 72; the second Z-axis positioning members 71 are disposed on the second rod 112 located in the middle of the frame assembly 11, and are located at the bottom of the second rod 112 on the side near the first rod 111. The second Z-axis positioning member 71 has two opposing fourth inclined surfaces and a fourth plane, wherein the fourth inclined surfaces are inclined relative to the second rod 112 and gradually extend away from the bottom surface of the second rod 112; the fourth plane connects the two fourth inclined surfaces and is horizontal relative to the fourth inclined surfaces. Each conveying station 21 and working station 22 is provided with at least two Z-axis positioning units 72. Each Z-axis positioning unit 72 includes a third mounting frame 721 and a second Z-axis positioning roller 722. The third mounting frame 721 is disposed on the upper surface of the conveying station 21 and the working station 22. The third mounting frame 721 has a second roller mounting groove 7211. The second Z-axis positioning roller 722 is rotatably disposed in the second roller mounting groove 7211, and a portion of the second Z-axis positioning roller 722 protrudes from the upper surface of the roller seat 632. The second Z-axis positioning roller 722 is vertically disposed relative to the roller seat 632.

[0101] When the conveying carrier 1 moves to the conveying station 21 or the working station 22, the second inclined surface of the Y-axis positioning member 61 on the conveying carrier 1 contacts the Y-axis positioning roller 633, the third inclined surface of the first Z-axis positioning member 62 contacts the first Z-axis positioning roller 634, and the fourth inclined surface of the second Z-axis positioning member 71 contacts the second Z-axis positioning roller 722.

The third plane of component 62 contacts the second Z-axis positioning roller 722, and the fourth plane of the second Z-axis positioning component 71 contacts the second Z-axis positioning component 71. The conveying carrier 1 is lifted upward to a certain height by the first Z-axis positioning roller 634 and the second Z-axis positioning roller 722. The output end of the third telescopic component 522 of the X-axis positioning unit 52 extends, driving the pin 5231 and the X-axis positioning roller 5232 of the X-axis positioning structure 523 to extend and insert into the positioning groove 511 of the X-axis positioning component 51. At this time, the conveying carrier 1 is positioned on the conveying station 21 or the working station 22. When the conveying carrier 1 needs to leave the current station, the output end of the third telescopic component 522 of the X-axis positioning unit 52 retracts, driving the pin 5231 and the X-axis positioning roller 5232 of the X-axis positioning structure 523 to retract and exit from the positioning groove 511 of the X-axis positioning component 51. At this time, the conveying carrier 1 can leave the current station.

[0102] In some embodiments, the conveying system further includes at least one first blocking mechanism 8, which is disposed between the conveying component and the work station 22 to prevent the conveying carrier 1 from accidentally rushing out of the conveying component, thereby greatly reducing the risk of damage to the equipment on the work station 22 by the accidentally rushed-out conveying carrier 1.

[0103] Please refer to the following: Figure 17 and Figure 18In some embodiments, the first blocking mechanism 8 includes a first blocking bracket 81, a fourth mounting bracket 82, a rotating shaft 83, a second fixing member 84, a blocking member 85, a second buffer member 86, and a second driving member 87. The first blocking bracket 81 includes a base portion 811 and a fourth mounting portion 812. The base portion 811 is disposed on the ground between the conveying assembly and the working station 22. The fourth mounting portion 812 is disposed on the base portion 811 and has a third mounting hole. The fourth mounting bracket 82 is disposed on the fourth mounting portion 812 and has a fourth mounting hole. The fourth mounting hole and the third mounting hole are coaxially arranged. The rotating shaft 83 passes through the third mounting hole and the fourth mounting hole, and a portion of the rotating shaft 83 protrudes from the outer wall of the fourth mounting bracket 82. A mounting groove is formed on the surface of the portion of the rotating shaft 83 located outside the fourth mounting bracket 82. The second fixing member 84 is engaged in the mounting groove and connected to the fourth mounting bracket 82. The lower part of the blocking member 85 is disposed on the fourth mounting bracket 82 and connected to the rotating shaft 83. The second buffer 86 is disposed at the end of the blocking member 85 away from the fourth mounting bracket 82, and is disposed opposite to the first buffer 13 disposed at the end of the frame assembly 11. The second drive member 87 is disposed on one side of the fourth mounting portion 812. The second drive member 87 includes a second mounting member 871 and a fourth telescopic member 872. The second mounting member 871 is disposed on one side of the fourth mounting portion 812, and the fourth telescopic member 872 is disposed on the second mounting member 871. The output end of the fourth telescopic member 872 is connected to the side of the blocking member 85.

[0104] In this embodiment, the fourth telescopic member 872 is a cylinder. In other embodiments, the fourth telescopic member 872 may also be an electric push rod, etc., so it is not limited thereto. In this embodiment, when the cylinder push rod is in the extended state, the blocking member 85 is pushed by the cylinder push rod to be vertically positioned relative to the fourth mounting bracket 82. At this time, the first blocking mechanism 8 is in the blocking state. When the conveying carrier 1 moves accidentally towards the first blocking mechanism 8, the first buffer member 13 located at the end of the conveying carrier 1 hits the second buffer member 86. On the one hand, the first blocking mechanism 8 can stop the conveying carrier 1; on the other hand, the first buffer member 13 and the second buffer member 86 absorb part of the impact energy by deformation or compression, reducing the damage to the conveying carrier 1. When the conveying carrier 1 needs to move between the conveying assembly and the working station 22, the cylinder push rod retracts, the blocking member 85 rotates around the rotating shaft 83, and the blocking member 85 is pulled by the cylinder to a non-blocking position away from the conveying assembly. At this time, the first blocking mechanism 8 is in the non-blocking state, and the conveying carrier 1 can move between the conveying assembly and the working station 22. When the conveying carrier 1 does not need to move between the conveying component and the working station 22, the cylinder push rod extends, causing the first blocking mechanism 8 to switch to the blocking state.

[0105] Please refer to the following: Figure 19In some embodiments, the conveying system further includes at least one second blocking mechanism 9, which is disposed at the end of the work station 22 away from the conveying assembly, to prevent the conveying carrier 1 from accidentally rushing out of the work station 22. The second blocking mechanism 9 includes a second blocking bracket 91 and a plurality of third buffers 92. The second blocking bracket 91 is disposed on the ground at the end of the work station 22 away from the conveying assembly, and the plurality of third buffers 92 are disposed on the side of the second blocking bracket 91 facing the work station 22, to reduce the impact force when the conveying carrier 1 rushes out, and to reduce the damage suffered by the conveying carrier 1 when it rushes out.

[0106] The conveying system provided in this application, by setting a drive docking mechanism 3, enables the conveying carrier 1 to reciprocate between the conveying component and the working station 22. By setting a drive connection mechanism 4, the conveying carrier 1 can reciprocate between the conveying stations 21. The conveying system provided in this application can directly dock with the working station without the need for an additional transition roller bed, making the overall structure of the conveying system more compact, occupying less space, and saving space. Furthermore, both the conveying station 21 and the working station 22 are composed of a first base 23 and a second base 24 spliced ​​together. By using different numbers of first bases 23 and second bases 24, working stations 22 and conveying stations 21 with different station spacings can be spliced ​​together, thereby adapting to different production needs or equipment configurations, and has strong practicality. At the same time, by modularizing the first base 23 and the second base 24, it is helpful for the assembly and adjustment of the working station 22 and the conveying station 21, reducing assembly time and improving production efficiency; it also reduces non-standard parts, lowers production costs, and makes the structure of the working station 22 and the conveying station 21 more compact, reducing the floor space and saving space.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
