Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The label pasting structure provided by the embodiment of the utility model comprises the following components: the cambered surface sucker 10 and the air source 30 can be structurally shown by referring to fig. 3 and 4;

The cambered surface sucker 10 is provided with a picking surface, the cambered surface sucker 10 protrudes towards the picking surface, and the center of the protrusion is positioned at the center of the picking surface, so that the center of the cambered surface sucker 10 is firstly contacted with a to-be-pasted label 40, as shown in fig. 5;

The cambered surface sucker 10 is provided with a gas path channel penetrating through the pick-up surface, one end of the gas path channel is connected with the gas source 30, and the other end of the gas path channel is positioned on the pick-up surface. When the air source 30 provides negative pressure, the to-be-labeled 40 can be adsorbed and picked up; the air source 30, when provided with positive pressure, can assist in taking the label 40 to be adhered to the surface 50 to be adhered.

According to the technical scheme, the label sticking structure changes the plane pick-up label structure into the cambered surface pick-up label structure, and soft labels can be stuck on the stuck surface at one time without bubbles. The scheme is simultaneously suitable for the scenes such as laminating soft adhesive tape, high-temperature adhesive tape, electronic product soft films and the like.

The raised portions of the pick-up surface may be used to attach a multi-arc planar label, as described below with respect to example 123. As in example 1: when the bonding surface is a plane, the protruding radian of the cambered surface sucker is R100mm, and the example 23 is described by analogy

The protrusion of the pick-up surface can be used to attach a planar and multi-arc label, as shown in example 1 of fig. 1a, when the attaching surface is a planar surface, the protrusion arc radius of the arc suction cup is R100mm;

As shown in example 2 of fig. 1b, when the bonding surface is the concave surface of R100, the radius of the center of the protrusion of the cambered suction cup is R50mm, and the radius of the periphery is R100mm; the two examples are combined, namely the pick-up surfaces are positioned on the same spherical surface, and the pick-up device is applicable to the situation that the attached surface is a plane or a concave surface;

When the joint surface is a surface formed by two or more gradient radiuses, the radius of the convex cambered surface of the cambered surface sucker also needs to be correspondingly changed, the number of gradients is equal to that of the joint surface, and the cambered surface radius close to the center is smaller than that close to the edge; as shown in example 3 of fig. 1c, when the contact surface is a secondary step of the central concave R100 and the peripheral plane, the convex arc radius of the arc suction cup comprises two gradients, and the peripheral radius of the central radius R50mm is R100mm, i.e. the arc radius of the center is smaller than the peripheral arc radius.

Preferably, the cambered surface sucker 10 is made of a compressible material. Then, as shown in fig. 5, the height H of the cambered surface sucker 10 gradually decreases in the bonding process until the cambered surface becomes a plane, and the gas is discharged from the center to the periphery, so as to realize 0-bubble bonding.

Specifically, the compressible material is a soft material with elasticity, such as silica gel, so as to realize compressibility, and the compressible material automatically restores to the original state after being used, thereby being convenient for the next operation.

Further, the gas path channel includes: a central channel 21 and a peripheral channel, the structure of which can be seen with reference to fig. 2 and 3;

Wherein, the central channel 21 is located at the center of the picking surface, and a plurality of peripheral channels are distributed around the central channel 21 to match with the process of deforming from the center to the periphery when the cambered surface sucker 10 is compressed.

Preferably, the gas source 30 includes at least: a central air passage 31 and a peripheral air passage, the central passage 21 being connected to the central air passage 31 and the peripheral passage being connected to the peripheral air passage. By providing multiple air paths, one can be validated by another in the event of a failure, and different pneumatic effects can be applied at the center and around.

Specifically, the surrounding channels include: a first channel group and a second channel group;

Wherein the first channel group comprises a plurality of first channels 22 and the second channel group comprises a plurality of second channels 23, the structure of which can be seen with reference to fig. 2 and 4; the first channels 22 and the second channels 23 are alternately arranged around the central channel 21 to provide a uniform pneumatic action;

The gas source 30 includes at least: a first air path 32 and a second air path 33; the first channels 22 are connected to the first air path 32, and the second channels 23 are connected to the second air path 33. The advantages of providing a plurality of air passages can be referred to the foregoing description, and will not be described herein.

In this embodiment, the number of the first channels 22 and the second channels 23 is four, and they are uniformly distributed around the central channel 21, and the structure thereof is shown in fig. 2, and may be in a shape of a letter "field".

The negative pressure air circuit is changed into a multi-channel design, and each channel is provided with a negative pressure sensor, so that the label can be adsorbed on the cambered surface, and whether the label is completely adsorbed or not can be monitored in real time, so that the air source 30 can be regulated in real time; taking a label of 30mm multiplied by 30mm as an example, the negative pressure air path is designed into 9 channels, 3 channels of vacuum are designed, the vacuum layout is shown as shown in fig. 2, the central channel 21 does not share one channel of negative pressure vacuum with other channels, but is independently one channel of vacuum, so as to ensure that the label is adsorbed in the first time, and prevent the failure of label pickup caused by the fact that the vacuum of the central channel 21 cannot be formed due to poor vacuum effect formed by other channels; the negative pressure channel is designed to be 3 multiplied by 3, the space is 10mm, and the four channels are divided into two paths of vacuum control, so that when one path of vacuum formation fails, the other path of vacuum can be formed, and the label pickup success rate is ensured; the diameter of the vacuum hole is 1mm, and the vacuum hole is a critical value which is obtained through experiments, can ensure that the negative pressure suction can successfully pick up the label and can ensure that the label is sucked out of the critical value with the minimum deformation.

Further, the diameter of the air channel is 1mm, so that the negative pressure suction force can be ensured to successfully pick up the label, and the label can be sucked out of deformation.

Preferably, the air source 30 is capable of providing negative and positive pressure for suction pickup of the label 40 to be applied and for assisting in taking the label 40 to be applied against the surface 50 to be applied, respectively.

The negative pressure gas circuit adopts the succession of blowing and inhaling, namely: when the cambered surface absorbs the label, the negative pressure is generated simultaneously by 3 channels of vacuum of the 9 channels, the cambered surface starts to pick up the label, when the label contacts the surface of the product to be pasted, the vacuum negative pressure of the central air channel 31 corresponding to the central channel 21 is switched to positive pressure, so that empty drums generated by negative pressure adsorption before the central point of the label 40 to be pasted are blown out, at the moment, other 8 channels are still kept in a negative pressure state, then the cambered surface starts to gradually press down, the negative pressure of the first air channel 32 and the second air channel 33 is switched to positive pressure when the cambered surface is pressed down to the position to be pasted, so that empty drums generated by negative pressure adsorption before the relative position of the label 40 to be pasted and the surrounding channels are blown out, and the cambered surface continues to gradually press down until the complete label pasting work is completed, and the poor pasting bubbles caused by the empty drums generated by the negative pressure adsorption is perfectly avoided through reasonable alternation of negative pressure and positive pressure in the whole process.

In summary, the embodiment of the utility model discloses a label sticking structure, which uses an arc surface method to stick labels to remove air between the labels and the products to be stuck, and eliminates the situation of generating bubbles after sticking; the bulge part sucked by negative pressure is restored to be flat by adopting the blowing and suction successor principle, so that the condition of generating bubbles after lamination is eliminated.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
