[0037] As Figure 1 And Figure 2The utility model discloses a circular conveying mechanism, including backflow conveying device 1 and stacking device 2, backflow conveying device 1 includes two conveying lines 11, two transfer mechanism 12 and a plurality of jigs 13, two transfer mechanism 12 interval setting along the first direction (the first direction is the X direction of illustration), be provided with two conveying lines 11 between two transfer mechanism 12, two conveying lines 11 interval setting along the second direction (the second direction is the Y direction of illustration), and the transmission direction of two conveying lines 11 is opposite, conveying line 11 is used for conveying jig 13, and transfer mechanism 12 can be moved along the second direction and link two conveying lines 11 to realize the transfer of jig 13, and the first direction is vertically arranged with the second direction, every conveying line 11 is provided with at least one stacking device 2, and the stacking device 2 can stack the jig 13 on the conveying line 11 one by one to form the jig module 100 and be uniformly conveyed, or the stacking device 2 can disperse the jig module 100 on the conveying line 11 one by one to convey the jig 13 one by one.

[0038] It can be understood that the backflow conveying device 1 formed by the two conveying lines 11 with opposite transmission directions and the two transfer mechanisms 12 realizes the automatic recycling use of the jigs 13, improves the transmission efficiency of the jigs 13 and the materials in the jigs 13, and reduces the labor cost investment; through the use of the stacking device 2, the jigs 13 on the conveying line 11 can be stacked one by one to form the jig module 100 and be uniformly conveyed, or the jig module 100 on the conveying line 11 can be dispersed one by one to be conveyed one by one, thereby avoiding the situation that a large number of jigs 13 are flatly conveyed to occupy a long space of the conveying line 11, ensuring that the number of conveyed jigs 13 can be effectively reduced while ensuring that the length of the conveying line 11 is reduced, and the space occupied by the conveying line 11 is reduced.

[0039] In the embodiment, the second direction is a vertical direction, for the convenience of understanding, the two conveying lines 11 are respectively illustrated as an upper conveying line 113 and a lower conveying line 114 along the vertical direction, the stacking device 2 on the upper conveying line 113 is a first stacking device 26, the first stacking device 26 is used for stacking the jigs 13 one by one to form the jig module 100, the stacking device 2 on the lower conveying line 114 is a second stacking device 27, the second stacking device 27 is used for dispersing the jig module 100 one by one, and the transfer mechanism 12 adjacent to the feeding end of the upper conveying line 113 is a first transfer mechanism, the other transfer mechanism 12 is a second transfer mechanism, one end of the upper conveying line 113 adjacent to the first transfer mechanism is a third end, one end of the upper conveying line 113 adjacent to the second transfer mechanism is a fourth end, one end of the lower conveying line 114 adjacent to the second transfer mechanism is a fifth end, and one end of the lower conveying line 114 adjacent to the first transfer mechanism is a sixth end.

[0040] The jigs 13 are moved by the third end of the upper conveying line 113 in the first direction towards the fourth end, and are stacked one by one when conveyed to the first stacking device 26 to form a jig module 100, which is released from the first stacking device 26 to flow towards the fourth end, and can be transferred by the second transfer mechanism to the fifth end of the lower conveying line 114, which conveys the jig module 100 from the fifth end towards the sixth end, and disperses the jig module 100 into independent jigs 13 one by one at the second stacking device 27, which flows towards the sixth end one by one, and can be lifted by the first transfer mechanism into the upper conveying line 113, thereby realizing the automatic recycling of the jigs 13.

[0041] In this embodiment, as shown in Figure 1 、 Figure 2 and Figure 3 , the conveying line 11 includes a rack 111, a first motor and a first transmission roller 112, the length of the rack 111 extends in the first direction, a plurality of first transmission rollers 112 are rotatably connected to the rack 111, the rotation axis of the first transmission roller 112 extends in the third direction (the third direction is the Z direction shown in the figure), the first motor is drivingly connected to all the transmission rollers to drive the jigs 13 on the first transmission roller 112 to move, and the first direction, the second direction and the third direction are perpendicular to each other. The first motor is arranged on the rack 111, the output shaft of the first motor is drivingly connected to one of the first transmission rollers 112, and the other first transmission rollers 112 are drivingly connected by means of chain and toothed disc cooperation, etc. The first motor is started to drive all the first transmission rollers 112 to rotate, thereby realizing the conveying of the jigs 13 on the first transmission roller 112.

[0042] It should be noted that the distance between the two first transmission rollers 112 should be less than one third of the length of the jig 13 in the first direction, so as to avoid the jig 13 from falling between the adjacent first transmission rollers 112, and to ensure the stability of the conveying of the jig 13. Moreover, the rotation directions of the first motors of the two conveying lines 11 are opposite, so as to realize the opposite conveying directions of the two conveying lines 11.

[0043] Specifically, as shown in Figure 2 、 Figure 3 and Figure 7As shown, the conveying line 11 has a stacking position, and the stacking device 2 is arranged on the stacking position. The return conveying device 1 further comprises at least two blocking assemblies 14. The two sides of the stacking position along the first direction are respectively provided with at least one blocking assembly 14. The blocking assembly 14 comprises a fourth driving member 141 and a fourth blocking member 142. The fourth driving member 141 is in transmission connection with the fourth blocking member 142 to drive the fourth blocking member 142 to move along the second direction to block or separate the jig 13. For example, taking the upper conveying line 113 as an example, the fourth blocking member 142 of the blocking assembly 14 adjacent to the fourth end is always in the extended blocking state when the jig module 100 is stacked. When the jig 13 enters the first stacking device 26, the blocking assembly 14 adjacent to the fourth end is positioned to block so as to facilitate the stacking operation of the first stacking device 26. The blocking assembly 14 adjacent to the third end blocks the next jig 13. Only when the jig 13 in the stacking position is completed, the blocking assembly 14 adjacent to the third end releases the next jig 13 to enter the stacking position for stacking. Through the use of the blocking assembly 14, the positioning accuracy of the jig 13 in the stacking position can be improved, and the situation that multiple jigs 13 are stacked in the stacking position to affect the stacking process can be avoided, thereby ensuring the smoothness of the stacking operation.

[0044] Further, as shown in Figure 7 The blocking assembly 14 further comprises a roller 143 rotatably arranged on the fourth blocking member 142. The rotation axis of the roller 143 extends along the third direction. The fourth driving member 141 drives the fourth blocking member 142 to drive the roller 143 on the blocking member to block the jig 13. The first direction, the second direction and the third direction are perpendicular to each other. Through the arrangement of the roller 143, the jig 13 can slide along the roller 143 when the first stacking device 26 performs the lifting and stacking, thereby reducing the friction loss between the jig 13 and the fourth blocking member 142, and thereby prolonging the service life of the fourth blocking member 142 and the jig 13.

[0045] In some embodiments, as shown in Figures 2 to 7 The stacking device 2 comprises a mounting frame 21, a hopper 22, a lifting assembly 23 and a clamping assembly 24. The hopper 22 is spaced apart above the rack 111 through the mounting frame 21. The lifting assembly 23 is arranged below the rack 111 and can lift the jig 13 into the hopper 22. The clamping assembly 24 is arranged on the mounting frame 21 and can clamp the jig 13 lifted by the lifting assembly 23 in the hopper 22. Through the lifting of the jigs 13 by the lifting assembly 23 and the clamping of the jigs 13 by the clamping assembly 24, the jigs 13 can be stacked layer by layer and clamped in the hopper 22.

[0046] Further, the mounting frame 21 comprises two supports 211, the hopper 22 comprises two first stop pieces 221 and two second stop pieces 222, the two first stop pieces 221 are respectively installed on the two sides of the rack 111 along the third direction corresponding to one support 211, the first stop piece 221 has a first end 2211 and a second end 2212 arranged along the first direction, the jig 13 flows from the first end 2211 to the second end 2212, the side adjacent to each other of the two first stop pieces 221 and located at the position of the first end 2211 is respectively provided with a second stop piece 222, the length of the second stop piece 222 extends along the second direction, and the two first stop pieces 221 and the two second stop pieces 222 enclose a containing space 25 for placing the jig 13. By limiting the jig 13 on both sides along the third direction through the two first stop pieces 221, and limiting the jig 13 on the side adjacent to the first end 2211 along the first direction through the second stop piece 222, the situation that the jig 13 is inclined or dumped during the process of stacking the jig 13 to form the jig module 100 is avoided, and the use safety of the stacking device 2 is improved.

[0047] It should be noted that the interval height between the hopper 22 and the conveying line 11 should be greater than the height of one jig 13, so as to ensure that the jig 13 can enter or flow out of the hopper 22. Preferably, the interval height between the hopper 22 and the conveying line 11 should be less than twice the height of the jig 13, on the one hand to ensure the storage space of the hopper 22, and on the other hand to reduce the jacking distance of the jacking assembly 23 and improve the stacking efficiency.

That is, when the jigs 13 are stacked, the first driving member 2231 drives the third blocking member 2232 to extend out, so that the first blocking member 221, the second blocking member 222 and the third blocking member 2232 form the containing space 25, so that the jig module 100 is limited on both sides along the first direction and the third direction, ensuring the stability of the jig module 100 in the containing space 25 of the hopper 22. When the jigs 13 are stacked to a certain height to form the jig module 100, the first driving member 2231 drives the third blocking member 2232 to retreat and be spaced apart from the jig module 100, at this time, the jig module 100 is supported by the jacking assembly 23 and is clamped by the clamping assembly 24, the jig module 100 is placed on the conveying line 11 by the jacking assembly 23, and the jig module 100 can flow out of the hopper 22 by being separated from the third blocking member 2232.

[0049] Optionally, as shown in Figure 2 、 Figure 4 and Figure 7 , the jacking assembly 23 comprises a connecting plate 231, a second driving member 232 and at least two jacking blocks 233 spaced apart along the first direction, the second driving member 232 being arranged on the bottom side of the rack 111 through the connecting plate 231, all the jacking blocks 233 being connected to the driving end of the second driving member 232, and the second driving member 232 being capable of driving the jacking blocks 233 to pass through the gap between the first transmission rollers 112 and abut against and jack up the jigs 13 into the hopper 22. In actual application, the connecting plate 231 is further provided with a position sensor, the position sensor sensing the jigs 13 in the stacking position, the second driving member 232 driving the jacking blocks 233 to ascend, the jacking blocks 233 lifting the jigs 13 in the vertical direction until the jigs 13 are clamped by the clamping assembly 24; or the jacking blocks 233 jack up the jigs 13 to abut against the previous jig 13 in the hopper 22, the clamping assembly 24 releasing the clamping of the previous jig 13, and the second driving member 232 continuing to drive the jacking blocks 233 to ascend so that the clamping assembly 24 can clamp the jig 13 at the bottom of the hopper 22.

[0050] Further, the jig 13 is provided with a plurality of clamping grooves 131 on both sides of the third direction along the first direction, the length of the clamping groove 131 extends along the second direction, the magazine 22 is provided with a clamping assembly 24 on both sides of the third direction, the clamping assembly 24 includes a third driving part 241 and a clamping block 242, the third driving part 241 is arranged on the mounting frame 21, the clamping block 242 is arranged on the driving end of the third driving part 241, the clamping block 242 includes a connecting part 2421 and a clamping part 2422, the connecting part 2421 is connected with the third driving part 241, the connecting part 2421 is provided with a plurality of clamping parts 2422 on both sides of the jig 13 along the position corresponding to the clamping groove 131, the clamping part 2422 can be inserted into the clamping groove 131. Through the insertion of the plurality of clamping parts 2422 and the plurality of clamping grooves 131, the balance of the jig 13 supported on the clamping block 242 is ensured, and the inclination of the jig 13 is avoided. And the length of the clamping groove 131 extends along the vertical direction, so that when the lifting block 233 lifts the next jig 13 to contact the jig 13 clamped by the clamping block 242, the situation that the lifting block 233 excessively pushes the jig 13 to move and causes the third driving part 241 to be damaged is avoided. The clamping groove 131 provides a redundant space along the vertical direction, and the balance of the connection between the lifting assembly 23 and the clamping assembly 24 is improved.
