[0030] As shown in Figures 1-6 The utility model provides a kind of automatic labeler of snowflake hook, and snowflake hook includes wall sticking part 122, connecting rod part 121 and hanging part 123, connecting rod part 121 two ends are fixed wall sticking part 122 and hanging part 123 respectively, and hanging part 123 is in the shape of a star, and wall sticking part 122 is in the shape of a circular plate, and automatic labeler includes labeler table 1, positioning block 2, first material taking mechanism, label stripping machine 5 and labeler mechanism 6;

[0031] At least one positioning block 2 is fixed to the top surface of the labeler table 1, and one snowflake hook is placed on the top surface of each positioning block 2, wherein the wall sticking part 122 or the hanging part 123 of the snowflake hook is in contact with the top surface of the positioning block 2.

[0032] The first material taking mechanism includes a material taking assembly 3 and an adjusting assembly 4, the material taking assembly 3 is used for grabbing the snowflake hook on the positioning block 2, and the adjusting assembly 4 drives the material taking assembly 3 to move close to or away from the positioning block 2.

[0033] The label stripping machine 5 comprises a stripping plate 51 and a unwinding roller 52 on which a label roll is mounted, the label roll is attached with a plurality of labels (a structure known in the art), the label has two adhesive surfaces, one of which is provided with a paper tearing (here, release paper can be used), when the unwinding roller 52 rotates, the label on the label roll is separated from the label roll and located on the stripping plate 51, the tearing paper faces away from the stripping plate 51, and the other adhesive surface faces the stripping plate 51 (the working principle of the label stripping machine 5 is known in the art, and will not be described here. In addition, it should be noted that the stripping plate 51 is provided with release paper, which can prevent the label from sticking to the stripping plate 51);

[0034] The label sticking mechanism 6 comprises a first manipulator 61, a cross rod 62 and a suction cup 63, the output end of the first manipulator 61 is fixedly connected with the cross rod 62, and a plurality of suction cups 63 are fixedly connected with the cross rod 62 (the suction cup 63 is a pneumatic suction cup 63, and the specific principle is known in the art, which will not be described here), the first manipulator 61 is used to drive the suction cup 63 to move to adsorb the labels on the stripping plate 51 one by one and then transport them to the wall-attached part 122 of the snowflake hook opposite to the wall-attached part 122 of the snowflake hook grabbed by the taking component 3;

[0035] Embodiment one:

[0036] As shown in Figures 1-4 , when the snowflake hook is located on the top surface of the positioning block 2, the wall-attached part 122 of the snowflake hook is attached to the top surface of the positioning block 2, a through hole 101 is formed in the top surface of the label sticking table 1, the adjusting assembly 4 comprises a first cylinder 41, the output end of the first cylinder 41 is fixedly connected with a cross plate 42, a plurality of taking components 3 are arranged on the cross plate 42, and the first cylinder 41 drives the taking components 3 to move horizontally reciprocatingly above the positioning block 2 and above the through hole 101, the taking component 3 here can be a pneumatic gripper, which is used to fixedly clamp the connecting rod part 121 of the snowflake hook;

[0037] By attaching the wall-attached part 122 of the snowflake hook to the top surface of the positioning block 2, the contact area is larger than that of attaching the hanging part 123 to the top surface of the positioning block 2, so that the snowflake hook can be placed more stably on the positioning block 2, and the subsequent correcting mechanism 8 can further limit the position of the snowflake hook, so that the snowflake hook can be accurately and stably taken by the taking component 3;

[0038] Here, six suction cups 63 and six positioning blocks 2 are taken as examples for illustration, the distance between the six suction cups 63 and the distance between the six positioning blocks 2 are matched: when the snowflake hook needs to be labeled, the first mechanical arm 61 and the first cylinder 41 are adjusted at the same time, the first cylinder 41 drives the horizontal plate 42 to move close to the snowflake hook on the positioning block 2, until the material taking assembly 3 fixes and clamps the connecting rod part 121 of the snowflake hook, then the first cylinder 41 drives the material taking assembly 3 to move away from the positioning block 2, so that the snowflake hook moves to the upper side of the through hole 101, the first mechanical arm 61 drives the horizontal rod 62 to move, so as to drive the suction cup 63 to move, so that one label is adsorbed on each suction cup 63, and then the label is transported to the lower side of the through hole 101, at this time, one adhesive surface of the label faces upward and is opposite to the wall-attached part 122 of the snowflake hook, finally, the first mechanical arm 61 is adjusted to drive the suction cup 63 to move upward, so that the label gradually moves close to the wall-attached part 122, until the adhesive surface of the label is attached to the wall-attached part 122, then the material taking assembly 3 is adjusted to no longer clamp and fix the snowflake hook, and then the first mechanical arm 61 is adjusted to drive the suction cup 63 to move, so that the snowflake hook with the label is transported to the upper side of the conveying belt 11 located on one side of the labeling mechanism 6, finally, the suction cup 63 is controlled to no longer adsorb and fix the label (i.e. the snowflake hook), so that the snowflake hook with the label is automatically discharged and falls on the conveying belt 11;

[0039] Compared with the existing hook non-adhesive bonding device, the device can avoid the problem that the hook is easily damaged when the cutter is used to cut and bond the non-adhesive (i.e. the label in the present application) on the hook, and can also prevent the problem that the cutter may not be able to cut the non-adhesive after the cutter edge becomes blunt after long-term use, so that the non-adhesive cannot be bonded on the hook.

[0040] The positioning block 2 serves as a transfer station, after the material taking assembly 3 takes away the snowflake hook to be labeled on the positioning block 2, the next group of snowflake hooks can be fed when labeling, so that the efficiency is improved.

[0041] Embodiment two:

[0042] When the snowflake hook is located on the top surface of the positioning block 2, the wall-attached part 122 of the snowflake hook is attached to the top surface of the positioning block 2 (not shown in the figure), the automatic labeling device further comprises a motor for driving the material taking assembly 3 to flip, at this time, the through hole 101 in the labeling table 1 can also not be provided, but an additional motor is needed, the motor is fixed on the horizontal plate 42, and the output end of the motor is fixed with the material taking assembly 3, so that when the material taking assembly 3 clamps and fixes the snowflake hook, the first cylinder 41 drives the snowflake hook to move away from the positioning block 2, and then the motor drives the material taking assembly 3 and the snowflake hook to flip by one hundred and eighty degrees, so that the subsequent labeling work can also be performed by adjusting the labeling mechanism 6, and it is also needed to ensure that the material taking assembly 3 does not contact the top surface of the labeling table 1 during the flipping process, so that the overall size of the device is increased.

[0043] In addition, it should be noted that when the motor and the through hole 101 are not set, the labeling work can also be carried out, but in this case, the distance from the material taking assembly 3 to the top surface of the labeling table 1 needs to be set to be sufficient for the horizontal rod 62 and the suction cup 63 to be placed in, but in this case, the overall volume of the equipment will also be increased.

[0044] Embodiment three:

[0045] When the snowflake hook is located on the top surface of the positioning block 2, the hanging part 123 of the snowflake hook is attached to the top surface of the positioning block 2 (not shown in the figure), so that the through hole 101 does not need to be opened on the labeling table 1, but the hanging part 123 has poor support stability relative to the wall-hanging part 122, and cannot be conveniently corrected by the subsequent correction mechanism 8.

[0046] As shown in Figure 2 and Figure 4 , on the basis of the first embodiment, the wall-hanging part 122 of the snowflake hook is attached to the positioning block 2 with a size adapted to the attachment surface, and the automatic labeling equipment further comprises a correction mechanism 8, the correction mechanism 8 comprises a first limiting block 81, the first limiting block 81 is provided with a semicircular groove 811 opposite one side of the positioning block 2 (by setting the semicircular groove 811 as a semicircle, it is convenient for the wall-hanging part 122 to horizontally enter and exit the semicircular groove 811), the semicircular groove 811 is opposite the through hole 101, and the inner wall of the semicircular groove 811 is attached to the outer wall of the positioning block 2.

[0047] By setting the first limiting block 81 and the semicircular groove 811, when the snowflake hook is placed each time, the outer edge of the wall-hanging part 122 of the snowflake hook can be attached to the inner wall of the semicircular groove 811, thereby ensuring the accurate position of the snowflake hook each time (especially when placed manually by hand), and especially when the first air cylinder 41 is working and the labeling table 1 is slightly vibrating, the position of the snowflake hook on the positioning block 2 is prevented from deviating to a certain extent, thereby ensuring the accurate performance of the subsequent clamping and material taking work of the material taking assembly 3 and the labeling work.

[0048] On the basis of the above, as shown in Figure 2 and Figure 5 , the correction mechanism 8 further comprises a second air cylinder 82, a vertical plate 83 and a second limiting block 84, the second air cylinder 82 is fixed on the labeling table 1, the output end of the second air cylinder 82 is fixedly installed with the vertical plate 83, the vertical plate 83 is fixedly installed with the second limiting block 84 opposite one side of the positioning block 2, the second limiting block 84 is attached to the outer wall side of the positioning block 2, and the connecting edge between the attachment surface of the second limiting block 84 and the top surface of the positioning block 2 is chamfered;

[0049] When the snowflake hook is placed on the positioning block 2 and is attached to the inner wall of the semicircular groove 811, the second cylinder 82 is adjusted to drive the vertical plate 83 to move upward, the vertical plate 83 drives the second limiting block 84 to move upward along the outer wall of the positioning block 2, until the second limiting block 84 is in contact with the wall-attached part 122, and cooperates with the inner wall of the semicircular groove 811, to further limit the snowflake hook, so as to better prevent the first cylinder 41 from working and the label placing table 1 from slightly vibrating to cause the snowflake hook to deviate, thereby better ensuring that the subsequent clamping and taking material work of the taking material assembly 3 and the label placing work are accurately performed.

[0050] Through the chamfer thus arranged, when the snowflake hook is placed on the positioning block 2 and is slightly deviated, and the inner wall of the semicircular groove 811 is not in complete contact with the outer edge of the wall-attached part 122, the chamfer can push the snowflake hook to move when the second limiting block 84 moves upward, so that the inner wall of the semicircular groove 811 is in complete contact with the outer edge of the wall-attached part 122.

[0051] As shown in Figure 1 , Figure 3 and Figure 4 , a shooting unit 7 is arranged above the stripping plate 51, the shooting unit 7 is supported by a support frame 71, the shooting unit 7 is signal-connected to a controller, and the controller is signal-connected to the first mechanical arm 61.

[0052] Through the shooting unit 7, when the labels on the label roll are separated from the label roll and are located on the stripping plate 51, the shooting unit 7 shoots the labels on the stripping plate 51, and sends the collected position information to the controller, so as to facilitate the controller to control the first mechanical arm 61 to drive the suction cup 63 to move and accurately adsorb and take the labels, thereby ensuring that the subsequent label placing work is more accurate and avoiding label placing deviation.

[0053] As shown in Figure 1 , the automatic label placing equipment further comprises an injection molding machine 9 and a second taking material mechanism 10, and the second taking material mechanism 10 is used for transferring the snowflake hook molded by the injection molding machine 9 to the positioning block 2.

[0054] The second taking material mechanism 10 can comprise a second mechanical arm and a discharging assembly, the output end of the second mechanical arm is fixed with the discharging assembly, and the discharging assembly can be an adsorption disc or a pneumatic clamping jaw, so that the snowflake hook can be taken out and placed on the positioning block 2 after being molded by the injection molding machine 9, and automatic feeding work of the snowflake hook is realized.

[0055] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
