Fig. 1 and 2 are schematic views of a suction attachment device according to an embodiment of the present invention. As shown in fig. 1 and 2, the suction attaching device includes a frame 1, a first driving unit 2, a second driving unit 3, and a suction attaching unit 4. The first driving unit 2 is disposed on the frame 1. The suction unit 4 is connected to the first drive unit 2. The second driving unit 3 is movably arranged relative to the frame 1, and the second driving unit 3 is connected with the suction sticking unit 4. Wherein the first driving unit 2 is arranged to drive the suction and pasting unit 4 to make a feeding motion relative to the product, the second driving unit 3 is arranged to drive the suction and pasting unit 4 to rotate relative to the product, and the suction and pasting unit 4 is arranged to adsorb the object or release the adsorbed object.

In one embodiment, the article to be sucked or released by the suction unit 4 is, for example, but not limited to, a label; in another embodiment, the article to be sucked or released by the suction unit 4 may be a protective film or other articles to be attached to the product. As shown in fig. 3-5, the suction attaching device of the present embodiment can be used in the product label attaching process in the production line, wherein fig. 3 and 4 are only schematic, the shape, size, etc. of each mechanism in the drawings are not used to limit the present embodiment, and some structures that have no direct relation with the mechanism operation to be described below are also hidden in the drawings. Wherein, the first driving unit 2 drives the suction and pasting unit 4 to feed, and the second driving unit 3 drives the pasting of the suction and pasting unit 4.

Specifically, referring to fig. 3, the carrier 5 has a label 6 thereon, and the carrier 5 can transport the label 6 to a predetermined station of the suction and sticking device in the previous process (which belongs to the prior art and is not described in detail herein). After the carrier 5 enters the preset station, the suction and sticking unit 4 is separated from the carrier 5 by a distance, the first driving unit 2 drives the suction and sticking unit 4 to approach the surface of the carrier 5 along the feeding direction X and to adsorb the label 6 on the carrier 5, and then the first driving unit 2 drives the suction and sticking unit 4 to move reversely to reset to the initial position.

Referring to fig. 4 again, after the label 6 is adsorbed by the adsorption and sticking unit 4, the carrier 5 is withdrawn, the product 7 enters the station (or the adsorption and sticking device moves to the product 7), at this time, the adsorption and sticking unit 4 and the product 7 are separated by a distance, and the label 6 is parallel to the surface of the product 7 to be stuck. The second driving unit 3 drives the suction and pasting unit 4 to move along the oblique pushing direction Y (forming an angle with the feeding direction X), so that the suction and pasting unit 4 rotates relative to the product 7, and the label 6 forms an angle (the angle is an acute angle, and the specific angle can be different according to actual conditions) with the surface to be pasted of the product 7.

Referring to fig. 5 again, the first driving unit 2 drives the suction-sticking unit 4 and the label 6 to be pressed down to the product 7 so that one end of the label 6 contacts the surface of the product 7. After the label 6 contacts the product 7, the second driving unit 3 drives the suction and pasting unit 4 to rotate reversely, so that the angle between the label 6 and the product 7 is gradually reduced, and in the process, the first driving unit 2 continuously drives the suction and pasting unit 4 to move towards the product 7.

Referring to fig. 6 again, the attaching process is completed until the second driving unit 3 drives the suction and attachment unit 4 to rotate until the label 6 is parallel to the surface to be attached of the product 7, and the first driving unit 2 drives the suction and attachment unit 4 to feed the label 6 to the surface to be attached of the product 7, wherein the driving powers of the first driving unit 2 and the second driving unit 3 can be self-mastered by those skilled in the art, and are not described herein. From this, can make label 6 progressively attach to product 7 to the other end by one end, this can effectively avoid the production of attaching the bubble between label 6 and the product 7, has improved attached quality, has improved the pleasing to the eye degree of product.

As shown in fig. 1-6, in some embodiments, the suction patch unit 4 is pivotally connected to the first drive unit 2, and the suction patch unit 4 is also pivotally connected to the second drive unit 3. The first driving unit 2 is configured to drive the suction and pasting unit 4 to move along the feeding direction X, and the second driving unit 3 is configured to drive the suction and pasting unit 4 to move along the oblique pushing direction Y, so as to drive the suction and pasting unit 4 to rotate relative to the first driving unit 2 and the product 7, wherein the oblique pushing direction Y and the feeding direction X form an acute angle.

As shown in fig. 1 and 2, in some embodiments, the second driving unit 3 includes a transmission member 31, one end of the transmission member 31 is pivotally connected to the suction and pasting unit 4, and the transmission member 31 is configured to move in a controlled manner to rotate the suction and pasting unit 4.

As shown in fig. 3 and 4, in some embodiments, the second drive unit 3 may be provided as a rod cylinder, the transmission member 31 being provided as an output shaft of said rod cylinder. The transmission member 31 can drive the suction and pasting unit 4 to move in an oblique pushing direction Y, the oblique pushing direction Y forms an angle with the feeding direction X of the suction and pasting unit 4 driven by the first driving unit 2, and the driving forces of the first driving unit 2 and the second driving unit 3 act on different positions of the suction and pasting unit 4, so that the suction and pasting unit 4 can rotate relative to the first driving unit 2 when the second driving unit 3 drives the suction and pasting unit 4 to move.

In some other embodiments, the second drive unit 3 may also be a rotating electrical machine or the like.

In an alternative embodiment, as shown in fig. 7, the suction and pasting unit 4 is provided with a first protrusion 46, and the first protrusion 46 is used for being pivotally connected with the first driving unit 2. In addition, the cylinder shaft cannot be directly pivotally connected to the suction and pasting unit 4, and therefore, the transmission member 31 may also be provided with a connection block 32 at an end connected to the suction and pasting unit 4, so that the transmission member 31 is connected to the suction and pasting unit 4 through the connection block 32. For example, the first protrusion 46 may be movably inserted into the connecting block 32, or the connecting block 32 may be movably inserted into the first protrusion 46, and the first protrusion 46 and the connecting block 32 may be pivotally connected by a rotating shaft (not shown) that is sequentially movably inserted through them.

As shown in fig. 7, in an alternative implementation, the suction attaching unit 4 is provided with a second convex portion 47 in a protruding manner, and the second convex portion 47 may be formed in a table shape for pivotally connecting with the first driving unit 2 (the first driving unit 2 is not shown in fig. 7). Similarly to the above, the suction attaching unit 4 may also be pivotally connected to the first driving unit 2 through the second protrusion 47 and a rotating shaft 471 (refer to fig. 1 and 2) movably inserted into the second protrusion 47.

As shown in fig. 1, 2 and 7, in some embodiments, the suction patch unit 4 includes opposite first and second ends 41 and 42, the suction patch unit 4 being pivotally connected to the first drive unit 2 at the first end 41, and the suction patch unit 4 being pivotally connected to the second drive unit 3 at the second end 42. Therefore, when the second driving unit 3 drives the suction and pasting unit 4 to move linearly along the oblique pushing direction Y, the suction and pasting unit 4 can rotate relative to the product by taking the pivot point of the suction and pasting unit 4 and the first driving unit 2 as the center of a circle. When the first driving unit 2 drives the suction and pasting unit 4 to move, the suction and pasting unit 4 can make linear reciprocating motion along the feeding direction X.

As shown in fig. 7, in some embodiments, the suction and pasting unit 4 may be provided with a stop block 48, the stop block 48 is located on a side surface of the suction and pasting unit 4 facing the first driving unit 2 and located at a side of the first driving unit 2, when the suction and pasting unit 4 rotates relative to the first driving unit 2, the stop block 48 is used for limiting a maximum rotation angle of the suction and pasting unit 4, that is, when the suction and pasting unit 4 rotates by a small angle, the stop block 48 does not affect the rotation, and when the rotation amplitude of the suction and pasting unit 4 is too large, the first driving unit 2 is blocked by the stop block 48, so that the suction and pasting unit 4 cannot continue to move, thereby avoiding excessive rotation of the suction and pasting unit 4.

As shown in fig. 1 and 2, in some embodiments, the first drive unit 2 includes a guide rail 21 and a slide table 22. The guide rail 21 is provided on the frame 1 along the feeding direction X. The sliding table 22 is slidably disposed on the guide rail 21, and the sliding table 22 is connected to the suction and pasting unit 4 and is configured to be controlled to move along the guide rail 21 so as to drive the suction and pasting unit 4 to move. That is, the first drive unit 2 may be provided as a slide table cylinder. Of course, in some other alternative implementations, the first driving unit 2 may also be a motor or the like.

As shown in fig. 2, in some embodiments, the second driving unit 3 is provided on the slide table 22. In an alternative implementation, a bracket 33 may be provided on the slide table 22 of the first drive unit 2, and the second drive unit 3 is connected to an end of the bracket 33. Therefore, when the suction sticking device sticks a product, the sliding table 22 synchronously feeds along the guide rail 21 while the second driving unit 3 drives the suction sticking unit 4 to rotate, and drives the second driving unit 3 to synchronously feed, so that the label can be gradually stuck on the product while rotating towards the direction parallel to the surface of the product. This is because, as will be readily understood, if the second driving unit 3 drives the suction and application unit 4 to rotate, and there is no feeding between the suction and application unit 4 and the product, the label will gradually move away from the product in the process of being gradually parallel to the surface of the product until it is spaced apart from the product. Therefore, the suction and pasting unit 4 needs to be driven to feed while the suction and pasting unit 4 is driven to rotate and paste. Thereby, the feeding movement of the first drive unit 2 and the second drive unit 3 is performed by the guide rail 21 and the slide table 22, and the mechanism operation efficiency is higher.

Of course, in some other alternative implementations, the second driving unit 3 may be disposed on the frame 1 and driven to feed by a separate feeding driving unit (not shown), and the feeding driving unit may be driven to feed synchronously with the first driving unit 2. As will be readily appreciated by those skilled in the art, will not be redundantly described here.

As shown in fig. 1, 2 and 7, in some embodiments, the suction patch unit 4 includes a fixing plate 43 and a label suction plate 44. The fixed plate 43 is connected to the first drive unit 2, and the fixed plate 43 is connected to the second drive unit 3. The label suction plate 44 is connected to the fixing plate 43. In this case, the first convex portion 46, the second convex portion 47, and the stopper 48 may be disposed on the fixed plate 43, and more specifically, may be disposed on a side of the fixed plate 43 facing the first driving unit 2. The target plate 44 is attached to the side of the fixed plate 43 facing away from the first drive unit 2. The fixing plate 43 may be used to cooperate with a vacuum suction unit (not shown) and control the label suction plate 44 to suck or drop a label.

As shown in fig. 1, 2 and 7, in some embodiments, the first driving unit 2 further includes a connection plate 23, and the first driving unit 2 is connected to the suction and pasting unit 4 through the connection plate 23. Since the first driving unit 2 and the suction and pasting unit 4 have a pivot connection, when the first driving unit 2 is provided as a cylinder or a motor, the driving devices such as the cylinder and the motor are usually connected with other elements for linear movement, and do not form a pivot connection. Therefore, the connecting plate 23 is arranged for structural connection, so that the first driving unit 2 can drive the suction and pasting units 4 to do linear reciprocating motion, and the pivot points of the first driving unit and the second driving unit can also be used as the circle centers of the rotation of the suction and pasting units 4, so that the second driving unit 3 can drive the suction and pasting units 4 to rotate. In an alternative implementation, the connecting plate 23 and the second protrusion 47 are pivotally connected by a rotating shaft 471.

As shown in fig. 7, in some embodiments, the suction unit 4 has at least one suction hole 45 thereon, and the suction device further includes a vacuum unit connected to the suction unit 4 and configured to generate a first pressure or a second pressure in the suction hole 45 of the suction unit 4. The pressure outside the adsorption holes 45 is a third pressure, the first pressure is lower than the third pressure, and the second pressure is higher than the third pressure.

The vacuum suction unit is not shown in the figure, and may be a vacuum pump or the like, and the vacuum suction unit may include a vacuum suction tube (not shown) for connecting with the suction unit 4.

When the suction and sticking unit 4 sucks the label, the vacuum suction unit controls the first pressure generated in the suction hole 45 to make the pressure in the suction hole 45 smaller than the pressure outside the suction hole 45, so that the label can be sucked. When the suction and sticking unit 4 loosens the sucked label to stick the label to the product, the vacuum suction unit controls the second pressure generated in the suction hole 45 to make the pressure in the suction hole 45 greater than the pressure outside the suction hole 45, so that the label can be put down.

The suction holes 45 may be through holes that penetrate the fixing plate 43 and the label suction plate 44 and communicate with each other, or blind holes that do not penetrate the fixing plate 43 but penetrate the label suction plate 44 and communicate with each other on the fixing plate 43 and the label suction plate 44. The vacuum suction unit may be connected to a side surface of the label suction unit 4 (which may be the fixing plate 43 or the label suction plate 44) through a vacuum suction tube (not shown), and further connected to the suction hole 45, and the suction hole 45 has an opening on the label suction plate 44 facing the label or the product, so that the vacuum suction unit may control the label suction plate 44 to suck or release the label.

After the label is sucked by the suction and sticking unit, the second driving unit drives the suction and sticking unit to form an angle with the plane to be attached of the product and drives the suction and sticking unit to rotate until the suction and sticking unit is attached to the plane to be attached of the product in parallel, so that the label is gradually attached to the surface to be attached of the product from one end to the other end, bubbles are prevented from being generated between the label and the product, and the attaching quality can be ensured.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
