[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] See also Figure 1-10 The present invention provides a technical solution: a method for producing a gift box by visually assisted detection, comprising the following steps: Preparing a primary box 1: printing, pressing, creasing, and folding a paperboard to obtain a primary box 1, wherein the primary box 1 comprises a top cover 12 and a box body 11 connected to each other, and the edge of the top cover 12 and the edge of the box body 11 can overlap in design; Inspection: grab the top cover 12 and flip it in the first direction, so that after the primary box 1 is lifted, the top cover 12 and the box body 11 can fit together under the action of gravity, and then visually inspect whether the edge of the top cover 12 is aligned with the edge of the box body 11; Putting in accessories: turning over the primary box 1 in which the top cover 12 and the box body 11 are aligned in the second direction, so that the top cover 12 and the box body 11 are open, and then putting accessories in the box body 11; Stacking: turning over the top cover 12 of the primary box 1 containing the accessories along a first direction, so that the top cover 12 and the box body 11 of the primary box 1 are attached to each other under the action of gravity, thereby obtaining a gift box, and stacking the gift boxes; The first direction is a flipping direction of the canopy 12 when it is closed, and the second direction is opposite to the first direction.
[0026] Specifically, the cardboard used in the preparation of the primary box 1 is one of gray cardboard, white cardboard or kraft cardboard, the printing method used in the preparation of the primary box 1 includes one or more combinations of hot stamping / hot silver, UV printing, embossing and laminating, the pressing / creasing in the preparation of the primary box 1 is completed by a die-cutter / creasing machine respectively, the folding equipment used in the preparation of the primary box 1 is one of a semi-automatic folding machine or a fully automatic folding machine, and the adjacent edges of the folded cardboard in the preparation of the primary box 1 are bonded together by an adhesive to obtain the primary box 1, which consists of a top cover 12 and a box body 11.
[0027] It also includes a mechanical arm 2, which includes a driving component 21 and a grabbing component 22. The driving component 21 is used to drive the grabbing component 22 to rotate so that the canopy 12 can be flipped along a first direction, and the driving component 21 remains in a vertical state.
[0028] In the detection step, the grabbing assembly 22 includes an L-shaped arm 222, one end of the L-shaped arm 222 is rotatably connected to the top of the driving assembly 21, and the other end of the L-shaped arm 222 is rotatably connected to a turntable 223, and L-shaped rods 224 are fixedly connected to both sides of the turntable 223, wherein a counterweight 225 is fixedly connected to the surface of the L-shaped rod 224 on one side, and a suction cup 221 is fixedly connected to the bottom of the turntable 223. When the grabbing detection is performed between the canopy 12 and the box body 11, the two sides of the L-shaped rod 224 are stuck on the two sides of the canopy 12, at this time, the edge line of the canopy 12 and the L-shaped rod 224 are perpendicular to each other, and the top of the canopy 12 is adsorbed by the suction cup 221, so that the canopy 12 is fixedly attached to the box body 11. The cover 12 is caught, and when the L-shaped arm 222 rotates, the suction cup 221 adsorbs the cover 12 and the box body 11 and suspends them in the air. Due to the setting of the turntable 223, the L-shaped rod 224 drives the cover 12 to rotate, and due to the setting of the counterweight block 225, one side of the L-shaped rod 224 is always at the bottom, that is, the L-shaped rod 224 can be kept horizontal with the vertical plane, so that the edge line of the cover 12 can be kept horizontal with respect to the ground, preventing the visual flush situation caused by the edge line of the cover 12 and the edge line of the box body 11 being tilted due to the adsorption of the cover 12 by only the suction cup 221, thereby improving the accuracy of detection.
[0029] In the detection step, after the primary box 1 is transported to the bottom of the grabbing assembly 22, the grabbing assembly 22 grabs the canopy 12 and then flips the grabbing assembly 22 vertically. The maximum vertical flipping angle of the grabbing assembly 22 is 90° to 120°.
[0030] Specifically, the obtained primary box 1 is transported to the front of the robot arm 2 by the conveyor belt, and then the robot arm 2 grabs the gift box on the conveyor belt. When grabbing, the grabbing component 22 is driven by the driving component 21, and the top of the top cover 12 is sucked and grabbed by the suction cup 221 on the grabbing component 22, wherein the number of the suction cups 221 is at least two, so as to prevent the top cover 12 from rotating when being grabbed, that is, to make the grabbing component 22 more stable when grabbing the top cover 12. Since the grabbing component 22 only grabs the top cover 12 of the gift box, the gift box When rising, the canopy 12 and one side of the box body 11 rotate and open, and the grab assembly 22 flips along the first direction. During the flipping process, the canopy 12 and the box body 11 gradually close until they are tightly closed. When the grab assembly 22 flips along the first direction, the flipping angle is at least greater than 90°. In order to ensure that the canopy 12 and the box body 11 can be tightly closed, when the flipping angle is less than 90°, the canopy 12 and the box body 11 cannot be completely closed, so a flipping angle of 90° to 120° is more appropriate.
[0031] Furthermore, in the detection step, the edges of the top cover 12 and the box body 11 are detected by visual detection. The visual detection system is located at the front side of the robot arm 2. The visual detection system detects whether the edges of the top cover 12 and the box body 11 are aligned. During the visual detection, an image capture device, such as CMOS or CCD, is used to capture the edges of the top cover 12 and the box body 11 and convert them into image signals, which are then transmitted to a dedicated image processing system. The image processing system converts these image signals into digital signals based on information such as pixel distribution, brightness, color, etc., and performs calculations to extract the positional features of the edges of the top cover 12 and the box body 11 on the gift box being detected, that is, the inclination between the edges of the top cover 12 and the box body 11. The tilt angle is set in advance to a threshold of the tilt angle between the top cover 12 and the edge of the box body 11 to be within 2°, and the detection result is output based on the preset threshold value to determine whether it is qualified. When it is detected that the tilt angle between the top cover 12 and the edge of the box body 11 is less than or equal to 2°, the detection result is determined to be qualified. Thereafter, the gripping component 22 is used to flip and place the accessories in the second direction. When it is detected that the tilt angle between the top cover 12 and the edge of the box body 11 is greater than 2°, the detection result is determined to be unqualified. The unqualified primary box 1 is placed in the recycling area 3 for recycling by the robotic arm 2, thereby realizing automated detection of the tilt angle of the top cover 12 and the box body 11 of the gift box through visual inspection, thereby determining whether the primary box 1 is qualified.
[0032] In the step of inserting the accessories, the maximum vertical flipping angle of the grabbing assembly 22 is 30° to 60°.
[0033] It also includes a recycling place 3 . In the inspection step, after the visual inspection is completed, the primary boxes 1 whose top covers 12 and box bodies 11 cannot be aligned are transported to the recycling place 3 .
[0034] Specifically, the recycling place 3 is set around the robotic arm 2, and a recycling box is placed at the recycling place 3. If an unqualified primary box 1 is detected, the unqualified primary box 1 is placed into the recycling box through the robotic arm 2. When the recycling box is full of unqualified primary boxes 1, the staff will take the recycling box away and collect it for recycling. After recycling, the empty recycling box will be put back to the recycling place 3, and the unqualified primary boxes 1 will be recycled repeatedly.
[0035] Among them, in the step of placing the accessories, the accessories are manually placed into the interior of the box body 11 to ensure that the edge of the accessories matches the edge of the box body 11 to prevent the accessories from exceeding the edge of the box body 11. If the accessories are found to be loose or exceed the edge, the accessories are manually adjusted to the interior of the box body 11.
[0036] In the step of placing the accessories, the top cover 12 with the accessories placed thereon is closed with the box body 11 by using the grabbing assembly 22, and the grabbing assembly 22 is turned vertically at an angle of 90° by the driving assembly 21.
[0037] Specifically, in the step of putting in accessories, the accessories include ribbons, greeting cards, handles and light strings. All the scattered accessories mentioned above are put into a bag to facilitate putting them into the interior of the box body 11. When putting the accessories into the interior of the box body 11, care should be taken to place all the edges of the accessories inside the box body 11 to avoid the edges of the accessories exceeding the interior of the box body 11. If the accessories exceed the interior of the box body 11, it will affect the subsequent tightening of the top cover 12 and the box body 11. If there are accessories that exceed the range of the box body 11, their positions should be adjusted in time until the positions of the accessories are completely placed inside the box body 11. After placing the accessories, the grabbing assembly 22 is flipped along the second direction until the flipping angle is 90°. At this time, the top cover 12 and the box body 11 are just closed, and the angles between the top cover 12 and the box body 11 and the ground are just kept vertical, which makes it convenient to stack the gift boxes neatly in the later stage. The ribbons can be used to decorate the gift boxes to increase their aesthetics. The ribbon can be tied into bows, curly stripes, gold and silver edges, etc., to match the characteristics, color, theme, etc. of the gift. Greeting cards can be written with blessings or words of thanks to increase the emotional value of the gift. The content of the card should be related to the theme of the gift and reflect the intention of the giver. The handle can be PU leather handle, plastic handle, etc., to facilitate the recipient to carry the gift box. The light string can add brightness and visual effects to the gift box.
[0038] The mobile shelf 4 is included and is used for stacking the gift boxes which have been filled with accessories and closed.
[0039] Among them, in the stacking step, the grabbing component 22 is kept at a vertical flip angle of 90° unchanged and horizontally transferred to a position on the same vertical plane as the mobile shelf 4. The grabbing component 22 is moved vertically up and down to adjust and release the suction cup 221 to stack the gift boxes on the mobile shelf 4.
[0040] Specifically, the mobile shelf 4 is moved to the side of the robot arm 2, and then the gift boxes with accessories placed and vertically closed are placed on the mobile shelf 4 through the robot arm 2. When stacking, the vertical flip angle of the grabbing component 22 is kept unchanged at 90°, and then the grabbing component 22 is horizontally rotated to a position on the same vertical plane as the mobile shelf 4. Thereafter, the grabbing component 22 absorbs the gift boxes and moves vertically up and down and adjusts the height between the mobile shelf 4. After adjustment, the suction cup 221 is released to stack the gift boxes on the mobile shelf 4.
