Description

Technical Field

[0001] The present invention relates to the technical field of packaging box processing, and in particular to an assembling device for an anti-counterfeiting buckle of a packaging box. Background Art

[0002] Gift boxes protect products, convey product information, and promote them. To prevent and eliminate counterfeit and substandard products, anti-counterfeiting buckles are typically used. During box production, the buckle is first applied to the raw gray board before the box body is formed. The buckle consists of a raised portion and a rim surrounding the raised portion. During assembly, the rim is fixed to the outside of the gray board, while the raised portion is inserted through a pre-perforated opening in the gray board. During molding, the raised portion sits inside the box, providing an anti-counterfeiting feature. After molding, the gray board is covered with an exquisite decorative outer layer. Once closed, opening the box will destroy itself, making it impossible to restore it.

[0003] The existing packaging box anti-counterfeiting buckles are mostly assembled manually, and the anti-counterfeiting buckles are manually glued to the gray board. The production consumes a lot of manpower, and there will be differences in the anti-counterfeiting buckles assembled by different workers, resulting in a high production defect rate, poor accuracy and low production efficiency.

[0009] A further improvement of the present invention is that the unloading mechanism includes a gray board moving assembly for moving the gray board from the assembly turntable, and a pair of feed rollers are provided along the moving path of the gray board moving assembly. The feed rollers are provided with an annular groove for avoiding the anti-counterfeiting buckle protrusion, and the groove width of the annular groove is adapted to the size of the anti-counterfeiting buckle protrusion. The height of the transport gap between the two feed rollers is adapted to the feeding height of the gray board moving assembly, and a discharge conveyor belt is provided on the discharge side of the feed roller.

[0010] A further improvement of the present invention is that the gray board moving assembly includes a suction cup bracket, and a telescopic suction cup assembly is slidably connected to the lower end surface of the top plate of the suction cup bracket, and the telescopic suction cup assembly includes a telescopic rod with a telescopic end vertically downward, and a plurality of suction nozzles are provided at the end of the telescopic rod, and the moving path of the telescopic suction cup assembly is located above the positioning groove.

[0011] A further improvement of the present invention is that the button body placement assembly includes a positioning platform, the picking robot includes a first robot and a second robot arranged on the positioning platform and a third robot slidably connected above the assembly turntable, the first robot is slidably connected above the discharging slide along its length direction, a loading placement slot is provided on the positioning platform along the moving direction of the first robot, a rotating shaft is provided on one side of the loading placement slot, the second robot is rotatably connected to the rotating shaft, and a positioning placement slot is provided below the moving direction of the third robot on the positioning platform, the second robot takes the anti-counterfeiting buckle from the loading placement slot and then rotates counterclockwise 90° to reach directly above the positioning placement slot, and the third robot takes the anti-counterfeiting buckle in the positioning placement slot and then slides to directly above the positioning slot and places the anti-counterfeiting buckle.

[0012] A further improvement of the present invention is that each group of positioning grooves has two, the discharge slide of the vibration plate loader is a double-track slide, and the picking robot is provided with two groups and corresponds to each slide of the double-track slide.

[0013] A further improvement of the present invention is that the alignment groove and the positioning groove are located on the same axis, the sizes of the positioning groove, the loading groove and the alignment groove are all adapted to the anti-counterfeiting buckle and the bottom of the grooves are all provided with induction electric eyes.

[0014] A further improvement of the present invention is that four groups of negative pressure suction heads for fixing the gray board are arranged at intervals on the assembly turntable, each group of negative pressure suction heads corresponds one-to-one to each group of positioning grooves, and the suction ports of the negative pressure suction heads are flush with the upper end surface of the assembly turntable.

[0015] The beneficial effects of the present invention are:

[0016] First, the present invention can replace manual labor to install the anti-counterfeiting buckle on the gray board through the sequential coordination of the anti-counterfeiting buckle loading and placement mechanism, the glue dispensing mechanism, the gray board loading and placement mechanism and the unloading mechanism, thereby realizing automated installation, reducing manpower consumption, and greatly improving installation efficiency. Compared with manual installation, the error rate is low, it is less likely to produce defective products, and effectively improves installation accuracy and production efficiency.

[0017] Second, the present invention sets a telescopic rod above the positioning slot, and the telescopic end of the telescopic rod is vertically downward and a glue dispensing head is provided at the end thereof, which can accurately dispense glue on the anti-counterfeiting buckle below it, without the need to manually apply glue to the anti-counterfeiting buckle. The anti-counterfeiting buckle that has been glued can be quickly moved to the next step by assembling the turntable. The gray plate placed from above can well contact and adhere to the edge of the glued anti-counterfeiting buckle, and the glue dispensing is fast, which effectively improves production efficiency.

[0018] Third, the present invention sets a feeding pressure roller, and the feeding pressure roller is provided with an annular groove for avoiding the raised part of the anti-counterfeiting buckle. The groove width of the annular groove is adapted to the size of the raised part of the anti-counterfeiting buckle. It can fix the gray board after the anti-counterfeiting buckle is glued, and compact the contact between the gray board and the edge of the anti-counterfeiting buckle to avoid loose connection. The feeding pressure roller can also transport the gray board, so that it can enter the discharge conveyor belt more smoothly, and flatten the gray board to make it more flat.

[0019] Fourth, the present invention has four groups of negative pressure suction heads for fixing the gray board arranged at intervals on the assembly turntable, and each group of negative pressure suction heads corresponds one-to-one to each group of positioning grooves. The suction port of the negative pressure suction head is flush with the upper end surface of the assembly turntable. When the gray board is placed on the anti-counterfeiting buckle, the gap between the two can be reduced, thereby improving the adhesion effect. In addition, the gray board can be fixed during the rotation of the assembly turntable to avoid its displacement, reduce errors, and improve processing accuracy.

[0020] Fifth, the present invention uses the suction nozzle of the gray board moving component to pick up and put down the gray board. The contact is gentle and not easy to damage the gray board. Compared with clamping, the suction nozzle will not leave pressure scratches on the gray board, ensuring the beauty of the finished product. In addition, the gray board is lighter, and the suction nozzle can fully meet the transportation needs and reduce energy consumption.

[0021] Sixth, the present invention sets two positioning grooves, the discharge slide of the vibration plate loader is a double-track slide, and the picking robot is provided with two groups corresponding to each slide of the double-track slide, so that two anti-counterfeiting buckles can be assembled at one time. The packaging box with two anti-counterfeiting buckles is safer than the packaging box with the anti-counterfeiting buckle on only one side, and eliminates the possibility of forgery by prying up the box lid from the other side where the anti-counterfeiting buckle is not provided, thereby improving the safety performance of the product.

[0022] Seventh, the present invention is provided with a first manipulator, a second manipulator and a third manipulator. The first manipulator can place the anti-counterfeiting buckle from the loader onto the positioning table for transition adjustment. Because the distance between the double slides of the loader is very close, the distance between the two anti-counterfeiting buckles after discharge is also close. The second manipulator can adjust the distance between the two anti-counterfeiting buckles to adapt to the position where the anti-counterfeiting buckle needs to be set on the gray board. The third manipulator can place the anti-counterfeiting buckle with adjusted position onto the positioning groove, and then perform subsequent assembly. The placement process is smooth, and the position can be adjusted during movement, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
