Description

Technical Field

[0001] The utility model relates to a label suction cup component and belongs to the technical field of automation equipment. Background Art

[0002] In the process of automated label processing, it is a common operation method to transfer labels between different workstations through suction cup assemblies. Existing suction cup assemblies are usually completed by connecting the suction cups to the vacuum assembly to achieve negative pressure adsorption. The power of the connected vacuum device is usually set. If the power is too small, the label cannot be adsorbed. If the power is too large, the label may be wrinkled.

[0003] However, for a suction cup assembly of this structure, when the label to be adsorbed is offset at an angle and the suction holes on the suction plate are not all located above the label, air leakage occurs when the label is sucked upward, resulting in insufficient pressure in other holes, and ultimately the normal adsorption action of the label cannot be completed. Summary of the invention

[0007] The aforementioned label suction cup assembly is characterized in that: a groove corresponding to the shape and size of the downward pressure suction plate is provided at the bottom of the cavity, the downward pressure suction plate is embedded in the groove, and is fixedly connected to the cavity by a connecting piece passing through the cavity.

[0008] The aforementioned label suction cup assembly is characterized in that connecting guide pillars are arranged at the four corners of the cavity, an upper pressure plate which can move up and down relative to the cavity is connected to the connecting guide pillars, and a compression spring is mounted on the connecting guide pillars between the upper pressure plate and the cavity.

[0010] The aforementioned label suction cup assembly is characterized in that a driving connecting plate is also fixedly connected to the upper pressing plate.

[0012] The beneficial effect of the utility model is that by adding a one-way valve in the air extraction pipeline in the cavity, when the label position is offset, the one-way valve at the corresponding position is automatically closed to ensure that the suction force of other suction holes is normal, thereby achieving normal adsorption and transfer of the label.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] A label suction cup assembly comprises a cavity 10 and a downward pressure suction plate 20 fixed at the bottom of the cavity 10; wherein the downward pressure suction plate 20 is provided with a plurality of suction holes, an exhaust pipe 12 is provided in the cavity 10, a connecting pipe 11 connected to the exhaust pipe 12 is provided outside the cavity 10, and a plurality of one-way valves 13 respectively connected to the exhaust pipe 12 are also provided in the cavity 10; the suction holes are respectively connected to the one-way valves 13 at corresponding positions.

[0018] When the downward suction plate 20 is pressed down to the position of the label to be adsorbed, air is sucked out through the vacuum device connected to the connecting pipe 11, and the label is adsorbed through the negative pressure formed between the suction hole of the downward suction plate 20 and the label. In the normal adsorption process, since the air between the label and the one-way valve 13 is quickly evacuated, the one-way valve 13 is always in a normal conductive state; when the label to be adsorbed has a certain positional offset, if there is no label under the one-way valve 13 at the corresponding position to block the suction hole, during the process of the vacuum device pumping air, the one-way valve is automatically closed due to the effect of air pressure, thereby closing the air path of the corresponding suction hole and ensuring that the suction force of other suction holes is normal. In this embodiment, both ends of the cavity 10 are provided with connecting pipes 11 connected to the vacuum pipeline 12 to ensure the uniformity of the suction force inside the cavity 10.

[0019] The bottom of the cavity 10 is provided with a groove corresponding to the shape and size of the downward pressure suction plate 20, and the downward pressure suction plate 20 is embedded in the groove and fixedly connected to the cavity 10 by a connector 60 passing through the cavity 10. By embedding the downward pressure suction plate 20 in the cavity 10 and fixing it by the connector 60, the stability of the connection of the downward pressure suction plate 20 in the vertical direction and the horizontal direction is ensured, and the surface of the downward pressure suction plate 20 is smooth and flat through fine processing, and the label will not have bubbles and wrinkles when pressed down.

[0020] The four corners of the cavity 10 are provided with connecting guide pillars 50, and the connecting guide pillars 50 are connected to the upper pressing plate 30 that can move up and down relative to the cavity 10, and the connecting guide pillars 50 between the upper pressing plate 30 and the cavity 10 are sleeved with compression springs (not shown in the figure). The upper pressing plate 30 is also fixedly connected to the driving connecting plate 40. In the process of driving the connecting plate 40 to drive the upper pressing plate 30 and the lower pressing suction plate 20 to press down, due to the action of the compression spring, the pressing of the label by the lower pressing suction plate 20 is a slow pressing process, which can not only protect the product and equipment components, but also ensure that the lower pressing suction plate 20 can completely fit the label to be adsorbed.

[0021] In this embodiment, the bottom of the downward pressure suction plate 20 is evenly provided with 8 suction holes arranged in two rows, and the cavity 10 is provided with three one-way valves 13, the one-way valves 13 located on both sides are respectively connected to the two suction holes on both sides of the downward pressure suction plate 20, and the one-way valve 13 located in the middle is connected to the four suction holes in the middle of the downward pressure suction plate 20. The entire arrangement is even, which can meet the label adsorption in different situations.

[0022] In summary, the utility model provides a label suction cup assembly, which adds a one-way valve in the air suction pipeline in the cavity. When the label position is offset, the one-way valve at the corresponding position is automatically closed to ensure that the suction force of other suction holes is normal, thereby achieving normal adsorption and transfer of the label.
