[0037] See also Figure 1 , is a transfer mechanism 100 shown in an embodiment of the present application. The transfer mechanism 100 is used to be arranged between a conveying mechanism and a labeling mechanism to transfer products from the conveying mechanism to the labeling mechanism.

[0038] Exemplarily, the transfer mechanism 100 includes a support 10 , a transfer power source 20 , a transfer transmission mechanism 30 , a mounting assembly 40 , a lifting drive 50 , and a grabbing module 60 .

[0039] The bracket 10 adopts a U-shaped structural design, that is, it is composed of a first vertical pole, a second vertical pole and a cross bar. The first vertical pole and the second vertical pole are arranged side by side in a horizontal direction, and the cross bar is arranged above the first vertical pole and the second vertical pole, and the two ends of the cross bar in the length direction are respectively installed and fixed to the top of the first vertical pole and the top of the second vertical pole. In this way, the bracket 10 has a simple structure, good support stability, low manufacturing cost and good durability.

[0040] Optionally, the first vertical pole, the horizontal pole and the second vertical pole may be made of any one of steel bars, aluminum alloy bars and the like.

[0041] The transfer power source 20 is installed on the bracket 10. Specifically, the transfer power source 20 is installed on the crossbar.

[0042] The transfer power source 20 may be, but is not limited to, a servo motor.

[0043] The transfer transmission mechanism 30 is rotatably disposed on the bracket 10 and is in transmission connection with the transfer power source 20. The transfer transmission mechanism 30 can be, but is not limited to, a synchronous belt pulley mechanism, a sprocket mechanism, etc., with a stable transmission ratio, and can ensure the movement accuracy of the grab module 60.

[0044] The mounting assembly 40 is connected to the transfer transmission mechanism 30; the lifting drive 50 is mounted on the mounting assembly 40; the grabbing module 60 is connected to the lifting shaft of the lifting drive 50, and the grabbing module 60 includes a plurality of grippers 61 arranged side by side along a preset direction.

[0045] In summary, the implementation of the technical solution of this embodiment will obtain the following beneficial effects: when the transfer mechanism 100 of this solution is working, the transfer power source 20 first drives the transfer transmission mechanism 30 to drive the installation assembly 40 to move above the conveying mechanism, so that the grabbing module 60 is vertically opposite to the product on the conveying mechanism, and then the lifting drive 50 drives the grabbing module 60 to descend, so that the multiple grippers 61 of the grabbing module 60 can grab multiple products at the same time; then, the lifting drive 50 drives the grabbing module 60 to rise, and the transfer power source 20 drives the grabbing module 60 to transfer to the labeling mechanism, and the picking module releases the product into the labeling mechanism, thereby completing the transfer of the product from the conveying mechanism to the labeling mechanism; compared with the prior art, this solution can not only realize the automatic transfer of products, but also realize the synchronous transfer of multiple products at the same time, which can not only save labor costs and reduce the labor intensity of workers, but also greatly improve production efficiency and avoid affecting the production rhythm.

[0046] Please continue reading Figure 1 and Figure 3 In one embodiment, the grabbing module 60 further includes a driving source 62, which is connected to the plurality of grippers 61 to enable the grippers 61 to grab or release the product. The driving source 62 is used to provide the grippers 61 with the power required for work, so that the grippers 61 can grab or release the product, completing the transfer of the product from the conveying mechanism to the labeling mechanism.

[0047] Specifically, the driving source 62 in the above embodiment includes a gas distribution block 621 and a plurality of cylinders 622. The air inlet of the gas distribution block 621 is used to communicate with the gas supply device. The plurality of gas distribution ports of the gas distribution block 621 are connected to the cylinders 622 in a one-to-one correspondence. The cylinders 622 are connected to the gripper 61 in a one-to-one correspondence. During operation, the gas supply device delivers gas to the gas distribution block 621. The gas is evenly distributed through the gas distribution block 621 and flows into the corresponding cylinders 622 from each gas distribution port, so that each cylinder 622 obtains power and can control the gripper 61 to move, so as to realize the gripper 61 to grasp or release the product.

[0048] In the present application, the product may be a cylindrical lipstick, which is placed flat in a horizontal position in the loading slot of the loading block. Notches are respectively provided on opposite sides in the width direction of the loading block, and the notches are connected to the loading slot.

[0049] In one embodiment, the gripper 61 includes a first gripping plate 611 and a second gripping plate 612 that are spaced apart and opposite to each other, and the first gripping plate 611 and the second gripping plate 612 can move toward or away from each other.

[0050] Among them, a first pressing block 611a is protruded from the side of the first grab plate 611 facing the second grab plate 612, and a second pressing block is protruded from the side of the second grab plate 612 facing the first grab plate 611. The first pressing block 611a and the second pressing block are used to pass through the gap of the loading block and extend into the loading slot to clamp the product.

[0051] In the initial state, the first gripping plate 611 and the second gripping plate 612 are far apart, and the distance between them is greater than the width of the loading block, so that under the downward drive of the lifting driver 50, the loading block enters between the first gripping plate 611 and the second gripping plate 612. Then, the cylinder 622 drives the first gripping plate 611 and the second gripping plate 612 to move closer, and the first pressing block 611a and the second pressing block pass through the corresponding notches and extend into the loading slot to clamp and fix the lipstick, thereby achieving product grabbing.

[0052] In order to improve the firmness and reliability of product grasping and prevent the product from loosening and falling from the gripper 61 during transfer, the surface of the first pressing block 611a away from the first gripping plate 611 is covered with a first adhesive layer; and / or the surface of the second pressing block away from the second gripping plate 612 is covered with a second adhesive layer.

[0053] Preferably, the first adhesive layer and the second adhesive layer are provided at the same time to obtain a better gripping effect on the product. For example, the first adhesive layer and the second adhesive layer can be any one of double-sided adhesive, 3M adhesive, etc., which can be flexibly selected according to actual needs.

[0054] In the present application, the transfer transmission mechanism 30 adopts a synchronous pulley mechanism. In one embodiment, the mounting assembly 40 includes a mounting block 41 and a wedge block 42, the mounting hole is provided with a through hole, the transfer transmission mechanism 30 includes a transmission member 31, the transmission member 31 is inserted into the through hole, the hole wall of the through hole is provided with an inclined surface, the wedge block 42 is inserted into the through hole and tightly cooperates with the inclined surface to press and fix the transmission member 31.

[0055] The transmission member 31 is the synchronous belt in the synchronous pulley mechanism, which is fixed by the wedge block 42 and the mounting hole, so that the mounting assembly 40 can be driven by the transfer transmission mechanism 30 to move synchronously in the same direction, and the gripper 61 can be flexibly transferred back and forth between the conveying mechanism and the labeling mechanism. This installation method does not require drilling or gluing of the synchronous belt, and will not cause damage or pollution to the synchronous belt.

[0056] Please continue reading Figure 1 and Figure 2 Furthermore, the mounting assembly 40 includes a sliding block 43 and a sliding rail 44. The sliding rail 44 is mounted on the bracket 10. The sliding block 43 is connected to the mounting block 41 and is slidably disposed on the sliding rail 44. The sliding block 43 and the sliding rail 44 are slidably mounted and matched, which can guide and limit the reciprocating movement of the gripper 61, improve the posture stability of the gripper 61, and further ensure the alignment accuracy between the gripper 61 and the product, so that the gripper 61 can more effectively and accurately grasp the product.

[0057] In addition, based on any of the above embodiments, the transfer mechanism 100 further includes a first limit position sensor 70 and a second limit position sensor 80, which are mounted on the bracket 10 and are respectively located at both ends of the reciprocating path of the mounting block 41. The first limit position sensor 70 and the second limit position sensor 80 detect the position of the mounting block 41 moved to the two ends, and timely feedback information to stop the transfer power source 20 from working, so as to avoid rigid collision damage between the mounting block 41 and the bracket 10 and / or the transfer transmission mechanism 30, or noise that affects the user experience.

[0058] Furthermore, the transfer mechanism 100 further includes a gripping position sensor 90, which is disposed on the bracket 10 and arranged between the first limit position sensor 70 and the second limit position sensor 80. The gripping position sensor 90 is used to detect whether the mounting block 41 moves directly above the product, thereby ensuring that the gripper 61 accurately and effectively grips the product.

[0059] In addition to the above, the present application further provides a labeling device, which includes the transfer mechanism 100 as described in any of the above embodiments.

To make the description concise, not all possible combinations of the technical features in the above-described 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.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
