[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 A marking machine robotic arm assembly includes a fixed tube 1, a connecting flange 2 fixedly sleeved on the outer wall of the fixed tube 1, and a rotating shaft 3 rotatably connected to the inner wall of the fixed tube 1. The upper end of the rotating shaft 3 passes through the fixed tube 1 and extends to the top of the fixed tube 1. A first L-shaped connecting plate 4 is fixedly sleeved on the outer wall of the rotating shaft 3 located above the fixed tube 1, and both ends of the first L-shaped connecting plate 4 are provided with picking mechanisms. A driving mechanism is fixedly connected to the lower end of the fixed tube 1.

[0021] As can be seen from the above structure, by setting the first L-shaped connecting plate 4 and two picking mechanisms, during use, one picking mechanism is specifically responsible for picking up the loading material, and the other picking mechanism is specifically responsible for picking up the marked products for unloading. In this way, picking up products for loading and picking up products for unloading can be carried out simultaneously, thereby improving the loading and unloading efficiency of this device.

[0022] Furthermore, the picking mechanism includes a first cylinder 5, a connecting plate 6, a fixing plate 7, and an electromagnet 8. The first cylinder 5 is fixed to the upper surface of the first L-shaped connecting plate 4, and the driving end of the first cylinder 5 passes through the first L-shaped connecting plate 4 and is fixedly connected to the connecting plate 6. A strip groove 9 is formed on the upper surface of the connecting plate 6, and a bolt 10 is provided in the strip groove 9. One end of the bolt 10 passes through the strip groove 9 and is threadedly connected to the fixing plate 7. The electromagnet 8 is fixed to the lower surface of the fixing plate 7. By setting the first cylinder 5 and the electromagnet 8 to work together, when picking up the product, the first cylinder 5 drives the connecting plate 6, the fixing plate 7, and the electromagnet 8 to move downward, so that the electromagnet 8 contacts the product, and then the electromagnet 8 is activated. The electromagnet 8 attracts the product, and then the first cylinder 5 retracts and resets, thus completing the product pickup. Subsequently, the drive mechanism drives the rotating shaft 3 to rotate, which in turn drives the pickup mechanism to rotate, moving the product to the workstation. The first cylinder 5 then drives the electromagnet 8 and the product to move down to the workstation. The electromagnet 8 is de-energized, and the product falls to the workstation, thus completing the product loading and unloading. When installing the fixing plate 7 and the electromagnet 8, if the two electromagnets 8 are not on a circular path with the rotating shaft 3 as the axis, the bolt 10 can be loosened for adjustment to ensure that the electromagnets 8 are on a circular path with the rotating shaft 3 as the axis. This reduces the required precision during manufacturing, thereby facilitating manufacturing.

[0023] Furthermore, the driving mechanism includes a fixed seat 11 fixed to the lower surface of the fixed tube 1, and a second cylinder 12 is fixedly connected to one side wall of the fixed seat 11. A rack 13 is fixedly connected to the driving end of the second cylinder 12, and a gear 14 is meshed on one side wall of the rack 13. The lower end of the rotating shaft 3 passes through the fixed seat 11 and is fixedly connected to the gear 14. By setting the second cylinder 12 and the rack 13 to work together, the picking mechanism can be driven to rotate. When driving, the second cylinder 12 is activated, causing the second cylinder 12 to push the rack 13 to move. The moving rack 13 drives the gear 14 to rotate, and the rotating gear 14 can drive the rotating shaft 3 and the picking mechanism to rotate.

[0024] Furthermore, a second L-shaped connecting plate 15 is fixedly connected to the upper end of the rotating shaft 3, and a partition picking mechanism is fixedly connected to both ends of the second L-shaped connecting plate 15. By setting the second L-shaped connecting plate 15 and the partition picking mechanism, the weight on both sides of the rotating shaft 3 can be balanced, avoiding the rotating shaft 3 from being unbalanced on one side and affecting its rotation. The two partition picking mechanisms work in basically the same way as the picking mechanism. One partition picking mechanism picks up the partition to one side and then puts the partition down. The other partition picking mechanism picks up the partition to the position where the product is placed after marking is completed, and then puts the partition back into the product to complete the product isolation.

[0025] Furthermore, the partition picking mechanism includes a third cylinder 16 fixed to the end of the second L-shaped connecting plate 15, and the output end of the third cylinder 16 is fixedly connected to a mounting plate 17, and the lower surface of the mounting plate 17 is fixedly connected to a pneumatic suction cup 18; by setting the third cylinder 16 to cooperate with the pneumatic suction cup 18, the third cylinder 16 can drive the mounting plate 17 and the pneumatic suction cup 18 to move downward, so that the pneumatic suction cup 18 contacts the partition, thereby allowing the pneumatic suction cup 18 to pick up the partition.

[0026] Furthermore, a limiting rod 19 is fixedly connected to the upper surface of the connecting plate 6, and a sliding tube 20 is slidably sleeved on the outer wall of the limiting rod 19. The sliding tube 20 is fixed to the first L-shaped connecting plate 4. By setting the limiting rod 19 and the sliding tube 20 to work together, the limiting rod 19 and the sliding tube 20 can limit the movement of the connecting plate 6.

[0027] Furthermore, a pin groove is provided on the lower surface of the connecting plate 6, and a limit pin 21 is fixedly connected to the upper surface of the fixing plate 7, and the limit pin 21 is slidably connected to the pin groove; by setting the limit pin 21 to cooperate with the pin groove, it can be ensured that the fixing plate 7 is parallel to the connecting plate 6 when the fixing plate 7 is installed.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
