It combines decorative and functional requirements, and can print brand logos, product information, and artistic patterns. It is wear-resistant, corrosion-resistant, and adaptable to curved surfaces, meeting the requirements of brand promotion, durability, and mass production. It is the mainstream process choice for wine packaging.

[0004] Bottles are usually fed into the screen printing machine using a conveyor belt, but the feeding of bottles at the conveyor belt still relies on manual labor, resulting in a decrease in bottle production efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a feeding robot for a screen printing machine.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A screen printing machine loading robot includes a robot body. A mounting frame is provided on the transfer end of the robot body. Several suction nozzles are arranged side by side on the mounting frame. The suction nozzles are adapted to extend into the bottle opening and adsorb the bottle under the action of a negative pressure source.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a screen printing machine loading robot includes a robot body 1, for example, the robot body 1 can be a single-arm multi-axis robot, and a mounting frame 2 is provided on the transfer end of the robot body 1. A connecting rod 6 is provided on the mounting frame 2, and several adjustment units 7 are specifically provided on the connecting rod 6 along the axial direction.

[0022] Each adjustment unit 7 includes several suction nozzles 3 distributed circumferentially, and the diameters of the suction nozzles 3 within the same adjustment unit 7 are different. In a preferred example, the connecting rod 6 is rotatably adapted to the mounting frame 2. As the connecting rod 6 rotates, the suction nozzles 3 of different diameters will enter the downward-facing suction position. At this time, as the robot body 1 moves downward, the suction nozzles 3 in the suction position will engage with the bottle body. Subsequently, the suction nozzles 3 complete the suction of the bottle body under the action of a negative pressure source (not shown).

[0023] For example, the robot arm 1 can pick up several bottles arranged side by side at the disassembly station 4, and then transfer the bottles to the conveyor belt 5. Since the bottles are arranged in a row, the robot arm 1 only needs to put the bottles into the conveyor belt 5, and then control the negative pressure source to release the negative pressure supply to the suction nozzle 3 to complete the automatic feeding action of the bottles.

[0024] In some embodiments, multiple layers of bottles are arranged at the disassembly station 4 via partitions, and each layer of bottles is arranged in a row. Under the transfer of the robot body 1, the suction nozzles 3 in the suction position will transfer the bottles row by row onto the conveyor belt 5. After all the bottles in a single layer have been transferred onto the conveyor belt 5, the robot body 1 can also transfer several suction nozzles 3 to push the empty partitions away from the top of the next layer of bottles, and then the robot body 1 can transfer and load the next layer of bottles.

[0025] When the diameter of the bottle opening changes, the connecting rod 6 can be rotated to allow the suction nozzle 3 of the corresponding diameter to enter the suction position, which makes the robot of this invention more versatile.

[0026] In some embodiments, each adjustment unit 7 further includes a mounting sleeve 8 sleeved on the connecting rod 6, and the mounting sleeve 8 is fixed to the connecting rod 6, and in particular, can rotate synchronously with the rotation of the connecting rod 6, and a plurality of suction nozzles 3 are circumferentially arranged on the outer peripheral surface of the mounting sleeve 8. In addition, a connecting sleeve 9 is fixedly connected to each adjustment unit 7 on the mounting frame 2 via a mounting rod 13, and the connecting sleeve 9 is also sleeved on the connecting rod 6 as a whole, and the side wall of the mounting sleeve 8 fits against the side wall of the connecting sleeve 9.

[0027] The bottom of the side wall of the connecting sleeve 9 is provided with an air vent 10, and the connecting sleeve 9 is also provided with an air pipe 11 connected to the air vent 10, which is connected to a negative pressure source; the side wall of the mounting sleeve 8 is provided with several air passages 12 along the circumference, and the several air passages 12 are connected to the inner cavity of several suction nozzles 3 on the mounting sleeve 8.

[0028] As the connecting rod 6 rotates, different ventilation channels 12 will be opposite to the ventilation port 10. At this time, the negative pressure source, the air pipe 11, the ventilation port 10 and the corresponding ventilation channel 12 will form a connected fluid flow path. At this time, the negative pressure source can drive the suction nozzle 3 in the adsorption position to generate or release negative pressure.

[0029] Alternatively, each suction nozzle 3 may be provided with an air nozzle (not shown) that communicates with its inner cavity, and the air tube 11 and the air nozzle may be connected separately by a connection structure, for example, the two may be connected or disconnected by a threaded sleeve (not shown).

[0030] In a preferred embodiment, a sealing gasket 14 may also be fitted between the mounting sleeve 8 and the connecting sleeve 9. The sealing gasket 14 enhances the sealing between the mounting sleeve 8 and the connecting sleeve 9, preventing air leakage at the point where they meet. Correspondingly, the connecting rod 6 is also adapted to move axially, thereby pressing the sealing gasket 14 to achieve a sealing effect, or driving the mounting sleeve 8 to separate from the connecting sleeve 9, thus facilitating the rotational adjustment of the connecting rod 6.

[0031] For example, a multi-directional drive device 15 can be provided on the mounting bracket 2. The multi-directional drive device 15 can be specifically composed of a rotating component and an ejector component. The connecting rod 6 is installed on the rotating end of the rotating component. Under the drive of the rotating component, the connecting rod 6 will rotate; and under the drive of the ejector component, the rotating component and the connecting rod 6 will move axially as a whole.

[0032] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
