Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] refer to Figure 1 In one embodiment of the present application, a production line turnover mechanism is disclosed, which is used for turning over the product during the product transmission process, and includes: a transmission mechanism 1 for transmitting the product, a lifting mechanism 2 for the product to be separated from the transmission mechanism 1, a material taking mechanism 3 for transferring the product, and a turnover mechanism 4 for turning over the product.

[0031] The transmission mechanism 1 includes at least two conveyor belt devices 11 arranged side by side. The two adjacent conveyor belt devices 11 jointly transmit the material tray 12 for carrying the product. Both sides of the material tray 12 are respectively located on the two adjacent conveyor belt devices 11 for synchronous transmission.

[0032] Further, such as Figure 2 As shown, in some embodiments, to prevent the conveyor belt 11 and the material tray 12 from slipping, which could cause inconsistent speeds on both sides of the material tray 12 and result in tilting or shifting of the material tray 12, a mating ridge 111 and a guide groove 121 are provided at the contact point between the conveyor belt 11 and the material tray 12. The ridge 111 is located on the conveyor belt 11, and the guide groove 121 is located at the lower end of the material tray 12. The ridge 111 is embedded in the guide groove 121, limiting the conveying direction of the material tray 12.

[0033] refer to Figure 2 In some embodiments, the lifting mechanism 2 is arranged to be liftable below the transmission mechanism 1, and acts on the bottom of the material tray through the gap between the two adjacent conveyor belt devices 11.

[0034] Furthermore, the number of the ejecting mechanisms 2 is matched according to the number of the conveyor belt devices 11 in the transmission mechanism 1 .

[0035] Specifically, the number of the ejecting mechanisms 2 is one less than the number of the conveyor belt devices 11 .

[0036] More specifically, the lifting mechanism 2 includes a telescopic cylinder 21 having a telescopic end and a cylinder body. The telescopic end of the telescopic cylinder 21 is arranged toward the conveyor mechanism 1. A material support frame 22 is provided at the telescopic end of the telescopic cylinder 21. The telescopic end of the telescopic cylinder 21 drives the material support frame 22 to move upward through the gap between two adjacent conveyor belt devices 11, acting on the lower end of the material tray 12, and lifting the material tray 12, separating the material tray 12 from the conveyor belt device 11.

[0037] refer to Figures 3 to 5 In some embodiments, the material picking mechanism 3 is arranged above the transmission mechanism 1 in a liftable manner, and cooperates with the material lifting mechanism 2 to grab the product; the flipping mechanism 4 cooperates with the material picking mechanism 3 to flip the product.

[0038] A fixing frame 5 is provided above the transmission mechanism 1 , and the fixing frame 5 is used to fix the material taking mechanism 3 and the turning mechanism 4 above the transmission mechanism 1 .

[0039] Furthermore, the retrieving mechanism 3 includes a first lifting device 31 and a first material grabbing device 32. The first lifting device 31 can be implemented by a drive motor and a ball screw. The drive motor drives the screw to rotate, and the first material grabbing device 32 is movably connected to the screw, rising and falling as the screw rotates. The first lifting device 31 is arranged in a vertical direction.

[0040] Furthermore, a suction cup structure 33 is provided on the side of the first grabbing device 32 facing the transmission mechanism 1, and the product is adsorbed by forming a negative pressure at the suction cup structure 33, thereby grabbing the product.

[0041] In some embodiments, the flipping mechanism 4 includes a second lifting device 41, a rotary cylinder 42, and a second grabbing device 43 disposed on the rotary cylinder 42. The cylinder body of the rotary cylinder 42 is connected to the second lifting device 41 and rises and falls with the second lifting device 41. The rotary cylinder 42 has opposing rotatable ends, and the second grabbing device 43 is connected to the rotatable ends of the rotary cylinder 42.

[0042] Furthermore, the second gripping device 43 has a gripping side 431 and a facing side 432 , and a suction cup structure is also provided on the gripping side 431 to adsorb the product through negative pressure.

[0043] Furthermore, the turning mechanism 4 further includes a translation device 44 , and the second lifting device 41 is connected to the translation device 44 and moves horizontally along with the translation device 44 .

[0044] The flipping mechanism 4 has a receiving state and a discharging state. In the receiving state, the gripping side 431 of the second gripping device 43 faces the first gripping device 32 ; in the discharging state, the gripping side 431 of the second gripping device 43 faces away from the first gripping device 32 .

[0045] The specific steps of this application are as follows:

[0046] 1. The conveying mechanism 1 transfers the material tray 12 loaded with products to the top of the lifting mechanism 2;

[0047] 2. When the material tray 12 reaches the top of the lifting mechanism 2, the telescopic end of the telescopic cylinder 21 extends, and the bracket 22 acts on the bottom of the material tray 12, so that the material tray 12 leaves the conveying mechanism 1;

[0048] 3. The material picking mechanism 3 starts working. The first lifting device 31 drives the first grabbing device 32 to move downward, applying negative pressure to the product on the material tray 12. After the first grabbing device 32 successfully applies negative pressure to the upper surface of the product, the first lifting device 31 rises to separate the product from the material tray 12.

[0049] 4. The flip mechanism 4 works, and the second lifting device 41 drives the rotary cylinder 42 to descend, so that the second grabbing device 43 is staggered with the first grabbing device 32 in the horizontal direction and is lower than the horizontal height of the first grabbing device 32 to avoid movement interference between the two. Then, the translation device 44 drives the second lifting device 41 to translate, so that the second grabbing device 43 is located below the first grabbing device 32 and performs negative pressure adsorption on the lower surface of the product.

[0050] 5. After the second grabbing device 43 has finished grabbing the product, the negative pressure on the first grabbing device 32 is removed, and the first lifting device 31 drives the first grabbing device 32 to rise. When it rises to a point where it does not interfere with the rotation of the rotating cylinder 42, it stops. The rotating cylinder 42 rotates 180 degrees, so that the upper surface of the product faces downward, completing the flip.

[0051] 6. The second lifting device 41 drives the rotary cylinder 42 and the second grabbing device 43 to move downward synchronously. After the product is placed back on the material tray 12, the flipping mechanism 4 is reset.

[0052] In some embodiments of the present application, multiple sets of conveyor belt devices 11 can be set in the transmission mechanism 1, and correspondingly, multiple sets of lifting mechanisms 2, material taking mechanisms 3, and turning mechanisms 4 can also be set for cooperation.

[0053] like Figure 2 As shown, there are three conveyor belt devices 11 .

[0054] like Figures 3 to 5 As shown in FIG, the number of the material ejecting mechanism 2, the material taking mechanism 3, and the turning mechanism 4 is two groups.

[0055] Moreover, each institution can work independently without interfering with each other.

[0056] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0057] The above-described embodiments merely represent several implementation methods of the present application. 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 a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
