Description

Technical Field

[0001] This application relates to the technical field of detection devices, and particularly to a visual inspection system for wine boxes. Background Art

[0002] As Figure 1 shown, a wine box is usually made of cardboard printed with patterns. During the preparation process, the cardboard is folded to form a semi-finished product with both ends open, and the four side walls of the wine box are divided into two groups and are mutually attached in pairs to be flat. Subsequently, the semi-finished product is processed by spreading or other processes so that adjacent two side walls among the four side walls are perpendicular to each other to form a three-dimensional shape.

[0003] Regarding the patterns printed on the wine box, such as the anti-counterfeiting marks printed on the wine box, whether the printing quality is qualified also determines whether the wine box will become a defective product. For this reason, in the prior art, visual inspection technology is usually used to detect whether the anti-counterfeiting marks are qualified to prevent defective wine boxes printed with unqualified anti-counterfeiting marks from entering the market.

[0004] However, when the visual inspection system in the prior art visually inspects the anti-counterfeiting marks of the wine box, the wine box is in a three-dimensional shape. After detecting a defective wine box, usually due to the fact that the wine box has gone through many unnecessary preparation processes, it causes a waste of cost. Summary of the Invention

[0048] An embodiment of the present application provides a wine box visual inspection system, and the wine box visual inspection system includes:

[0049] A frame 1;

[0050] A feeding device 2 and a discharging device 4 arranged on the frame 1, and the discharging device 4 is arranged below the feeding device 2;

[0051] A flipping feeding device 3 slidably arranged on one side of the feeding device 2; and

[0052] A visual inspection device;

[0053] Wherein, the feeding device 2 is used to feed flat wine boxes into the flipping feeding device 3, the flipping feeding device 3 is used to clamp the wine boxes and move the wine boxes to the visual inspection device, the visual inspection device is used to perform visual inspection on the wine boxes, and the discharging device 4 is used to receive and store the wine boxes clamped by the flipping feeding device 3.

[0054] As Figure 1 shown, in this embodiment, by way of example, the frame 1 is used for the installation and fixation of each device, and universal wheels are arranged at its bottom for sliding on the ground. The frame 1 is specifically set in a cuboid shape, and one side in the width direction is open.

[0055] The feeding device 2 and the discharging device 4 are both arranged inside the frame 1, and the discharging device 4 is arranged below the feeding device 2. The flipping feeding device 3 is arranged on one side of the feeding device 2 and is located on the side where the opening in the width direction of the frame 1 is located. The flipping feeding device 3 is slidably arranged along the direction outside the frame 1, and its sliding direction is the width direction of the frame 1. When the flipping feeding device 3 slides close to the feeding device 2, the feeding device 2 feeds the flat wine box into the flipping feeding device 3, and the flipping feeding device 3 clamps it, and then sends it to the position where the vision inspection device is located for vision inspection.

[0056] As Figure 1 shown, it can be understood that the vision inspection device is arranged in the longitudinal section where the sliding path of the flipping feeding device 3 is located: the flipping feeding device 3 and the wine box it clamps are regarded as mass points, the sliding path of the flipping feeding device 3 is a horizontal straight line segment, and the vision inspection device is regarded as a mass point accordingly, and the vision inspection device is arranged in the longitudinal section where this straight line segment is located.

[0057] In this embodiment, the vision inspection device is arranged directly above the sliding path of the flipping feeding device 3 (the vision inspection device is not shown in the figure). When the flipping feeding device 3 clamps the wine box and moves it directly below the vision inspection device, the vision inspection device immediately conducts vision inspection on it; after the vision inspection of the wine box, the flipping feeding device 3 moves in the opposite direction to get closer to the frame 1 again, so as to facilitate sending the inspected wine box into the discharging device 4, and the discharging device 4 receives and stores the inspected wine box.

[0058] In summary, in this application, the flat wine box can be fed into the flipping feeding device 3 by the feeding device 2, then the wine box is clamped by the flipping feeding device 3, and then it is moved to the vision inspection device by the flipping feeding device 3, and the vision inspection device conducts vision inspection on it. After the vision inspection, it is sent to the discharging device 4 by the flipping feeding device 3, and finally received and stored by the discharging device 4.

[0059] Therefore, it can be understood that this application can achieve the vision inspection of flat wine boxes, and the qualified flat wine boxes can be further prepared into three-dimensional shapes after the vision inspection. Compared with the vision inspection of three-dimensional wine boxes, this application can avoid unnecessary preparation processes for unqualified defective wine boxes, and thus can achieve the purpose of cost saving.

[0060] Moreover, this application can sort out unqualified defective wine boxes in the discharging device 4 after the vision inspection of several flat wine boxes in the same batch, without having to separately strip out the wine box by stopping the machine when detecting an unqualified defective wine box. Therefore, this application also has a high detection efficiency.

[0061] It can also be understood that during the entire visual inspection process of this application, since the wine boxes are all flat structures, this application can also effectively improve the space utilization rate of the entire wine box visual inspection system and achieve the purpose of simplifying the structure of the wine box visual inspection system. Especially for the feeding device 2 and the discharging device 4, when the flat wine boxes are stacked in the feeding device 2 and the discharging device 4, it has the effect of saving space.

[0062] Specifically, a sliding table assembly 11 is provided on the frame 1. The flipping and feeding device 3 is slidably arranged on the sliding table assembly 11 and is rotatably arranged. The sliding table assembly 11 has a clamping position and a detection position along the sliding direction of the flipping and feeding device 3. The feeding device 2 is close to the clamping position, the visual inspection device is close to the detection position, and the flipping and feeding device 3 has a qualified position and an unqualified position that are inclined relative to the horizontal plane;

[0063] Among them, when the flipping and feeding device 3 slides to the detection position, the visual inspection device inspects the wine box clamped by the flipping and feeding device 3;

[0064] When the flipping and feeding device 3 slides to the clamping position, the wine box is clamped, or the wine box is released according to the detection result of the visual inspection device: if the visual inspection device detects that the wine box is qualified, the flipping and feeding device 3 rotates to the qualified position to release the wine box; if the visual inspection device detects that the wine box is unqualified, the flipping and feeding device 3 rotates to the unqualified position to release the wine box.

[0065] As Figure 1 shown, in this embodiment, by way of example, the sliding table assembly 11 extends along the width direction of the blanking table 14, and the visual inspection device is arranged directly above the sliding table assembly 11, so that when the flipping and feeding device 3 slides on the sliding table assembly 11, the visual inspection device can perform visual inspection on the wine box on the flipping and feeding device 3 at a specified position.

[0066] In this embodiment, the specified position where the visual inspection device on the sliding table assembly 11 performs visual inspection on the wine box is the "detection position", which is set at one end of the sliding table assembly 11 away from the feeding device 2. And one end of the sliding table assembly 11 close to the feeding device 2 constitutes the "clamping position". It can be understood that when the flipping and feeding device 3 slides to the clamping position, the feeding device 2 feeds the wine box into the flipping and feeding device 3, and the flipping and feeding device 3 clamps the wine box to synchronously drive the wine box to move.

[0067] As Figure 1 and Figure 2As shown, the flipping feeding device 3 is also rotatably arranged, that is, the angle of the flipping feeding device 3 relative to the horizontal plane is adjustable. The "qualified position" and the "unqualified position" are planes inclined relative to the horizontal plane. It can be understood that after the flipping feeding device 3 moves the wine box to the detection position and the visual detection device performs visual detection on the wine box clamped by the flipping feeding device 3, the flipping feeding device 3 slides back to the clamping position from the detection position and rotates to different inclined angles according to the detection result of the visual detection device, and then releases the wine box.

[0068] In this embodiment, if the visual detection device detects that the wine box is qualified, the flipping feeding device 3 rotates to the qualified position to release the wine box; if the visual detection device detects that the wine box is unqualified, the flipping feeding device 3 rotates to the unqualified position to release the wine box.

[0069] It can be understood that the sliding component in this embodiment is provided with a clamping position and a detection position, forming a relatively independent visual detection area, which can ensure the detection effect of the visual detection device for visual detection of the wine box; and the flipping feeding device 3 is provided with a qualified position and an unqualified position, which can distinguish between qualified and unqualified wine boxes when the wine boxes are sent to the blanking device 4, so as to facilitate the peeling of unqualified defective wine boxes, which is more convenient and fast.

[0070] It can also be understood that after the flipping feeding device 3 in this embodiment releases the wine box that has been visually detected at the clamping position, it can immediately clamp the wine box to be visually detected, and the visual detection process is in good order and has a high detection efficiency.

[0071] More specifically, the included angle between the qualified position and the unqualified position is 180 degrees.

[0072] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the qualified position is set as an acute angle, such as 30 degrees, and the unqualified position is correspondingly set as 210 degrees. Since the wine box in this application is flat, the difference between the qualified position and the unqualified position of the wine box lies only in the difference between the front and the back. In other words, if the two ends of the wine box are defined as the head and the tail respectively, then the wine box can be head-down and tail-up at the qualified position, while the wine box can be tail-down and head-up at the unqualified position.

[0073] It can be understood that setting the included angle between the qualified position and the unqualified position as 180 degrees in this embodiment can enable the qualified and unqualified wine boxes to be received by the blanking device 4 at the same position and at the same angle, and be stored by the blanking device 4. When the blanking device 4 stores the wine boxes, the qualified and unqualified wine boxes are stacked together, and in subsequent steps, the unqualified defective wine boxes can be selected from the blanking device 4 by distinguishing the head and the tail of the stacked wine boxes.

[0074] Of course, in some embodiments, the included angle between the qualified position and the unqualified position can also be an acute angle. For example, the qualified position is set to 30 degrees, and the unqualified position is set to 60 degrees. At this time, the qualified and unqualified wine boxes are received by the blanking device 4 at the same position at different angles and are stored via the blanking device 4. When storing, the qualified and unqualified wine boxes are stacked separately.

[0075] It can be understood that setting the included angle between the qualified position and the unqualified position to 180 degrees in this embodiment can not only enable the blanking device 4 to receive and store the qualified and unqualified wine boxes at the same time, but also make it easier for the wine boxes to be kept flush with each other during reception and storage. Therefore, this embodiment can simplify the structure of the blanking device 4 and enhance the structural compactness between various devices to further improve the space utilization rate within the system.

[0076] More specifically, the flipping and feeding device 3 includes a base 31 slidably disposed on the sliding table assembly 11, a first clamping plate 32 rotatably disposed on the base 31, a second clamping plate 33 slidably disposed along the thickness direction of the first clamping plate 32, a clamping cylinder 34 disposed on the first clamping plate 32 and connected to the second clamping plate 33, and a flipping motor 35 disposed on the base 31 and connected to the first clamping plate 32. The second clamping plate 33 is made transparent.

[0077] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, two bases 31 are spaced along the length direction of the frame 1, and both bases 31 are slidably disposed. The first clamping plate 32 is rotatably disposed between the two bases 31 and is connected to both bases 31. The first clamping plate 32 is rectangular, and its length direction is the width direction of the frame 1. The second clamping plate 33 is also rectangular, and the second clamping plate 33 is disposed on one side in the thickness direction of the first clamping plate 32, and the length and width of the first clamping plate 32 are not less than those of the second clamping plate 33. It can be understood that when the flipping and feeding device 3 clamps the wine box at the clamping position, the first clamping plate 32 is at the lower position and the second clamping plate 33 is at the upper position.

[0078] The second clamping plate 33 is slidably arranged, and its sliding is driven by a clamping cylinder 34. There are two groups of clamping cylinders 34, which are respectively arranged on both sides of the first clamping plate 32 in the width direction; the number of each group of clamping cylinders 34 is two, which are respectively arranged at both ends of the first clamping plate 32 in the length direction. The clamping cylinder 34 includes a cylinder base and a piston end slidably connected to the cylinder base. Its cylinder base is fixed on the side of the first clamping plate 32 away from the second clamping plate 33, and its piston end is connected to both sides of the second clamping plate 33 in the width direction. When the piston end of the clamping cylinder 34 expands and contracts, it can synchronously drive the second clamping plate 33 to slide along the thickness direction of the first clamping plate 32.

[0079] As Figure 1 and Figure 2 shown, it can be understood that when the wine box is clamped by the flipping feeding device 3, the first clamping plate 32 and the second clamping plate 33 are both kept horizontal first; then the second clamping plate 33 is driven by the clamping cylinder 34 to separate from the first clamping plate 32, so that a gap is formed between the second clamping plate 33 and the first clamping plate 32. Then the wine box is loaded onto the first clamping plate 32 by the loading device 2, and then the second clamping plate 33 is driven by the clamping cylinder 34 to approach the first clamping plate 32 again, and the wine box is clamped and fixed. After the wine box is clamped and fixed, the two bases 31 of the flipping feeding device 3 are driven to slide on the sliding table assembly 11, so as to synchronously move the wine box clamped between the first clamping plate 32 and the second clamping plate 33 to the detection position.

[0080] To facilitate visual inspection of the wine box between the first clamping plate 32 and the second clamping plate 33, the second clamping plate 33 should be set to be transparent. For example, the second clamping plate 33 is made of transparent glass, so that the visual inspection device can detect the wine box. In this embodiment, the visual inspection device detects whether the anti-counterfeiting label on the wine box is qualified. Of course, the first clamping plate 32 can also be set to be transparent, so that the visual inspection device can perform visual inspection on both the front and back of the wine box.

[0081] As Figure 1 and Figure 2 shown, the flipping motor 35 is arranged on one of the two bases 31, and the output shaft of the flipping motor 35 is connected to the first clamping plate 32. For example, the first clamping plate 32 is provided with a rotating shaft extending into the base 31, and the output shaft of the flipping motor 35 is connected to the rotating shaft, so that the first clamping plate 32 rotates under the drive of the flipping motor 35, and when the first clamping plate 32 rotates, it can synchronously drive the second clamping plate 33 to rotate through the clamping cylinder 34; if the first clamping plate 32 and the second clamping plate 33 clamp the wine box at this time, the purpose of driving the wine box to rotate to the qualified position or the unqualified position can be achieved.

[0082] It can be understood that after the visual inspection device inspects the wine box visually, the two bases 31 of the flipping feeding device 3 are used to move the wine box back to the clamping position, and then the flipping motor 35 rotates the first clamping plate 32 and the second clamping plate 33 to the qualified position or the unqualified position according to the inspection result of the visual inspection device. In this embodiment, if the inspection result of the wine box is qualified, the first clamping plate 32 and the second clamping plate 33 are rotated to 30 degrees; if the inspection result of the wine box is unqualified, the first clamping plate 32 and the second clamping plate 33 are rotated to 210 degrees. After the first clamping plate 32 and the second clamping plate 33 are rotated in place, the clamping cylinder 34 drives the second clamping plate 33 away from the first clamping plate 32 again to release the clamping of the wine box, and the wine box falls along the plate surface of the first clamping plate 32 or the second clamping plate 33 under the action of its own weight, and is received and stored by the feeding device 4.

[0083] More specifically, the sliding table assembly 11 includes a horizontally arranged slide rail 111, a sliding table 112 slidably arranged on the slide rail 111, and a sliding motor 113 for driving the sliding table 112 to slide, and the flipping feeding device 3 is arranged on the sliding table 112.

[0084] As Figure 1 and Figure 3 shown, in this embodiment, for exemplary illustration, only one set of sliding table assemblies 11 is provided, and it is arranged on one side in the width direction of the first clamping plate 32 and the second clamping plate 33. Among them, the slide rail 111 extends along the width direction of the frame 1, and the slide rail 111 is located outside the frame 1 and can be supported by several support members 13. The sliding table 112 is slidably arranged along the extending direction of the slide rail 111, and the sliding table 112 is driven by the sliding motor 113. The principle of the sliding table assembly 11 is known in the prior art and will not be elaborated here. Among the two bases 31 of the flipping feeding device 3, the base 31 provided with the flipping motor 35 can be connected to the sliding table 112.

[0085] On the other side in the width direction of the first clamping plate 32 and the second clamping plate 33, it can be supported by the guide rail assembly 12. The guide rail assembly 12 includes a guide rail 121 arranged parallel to the slide rail 111 and a guide slider 122 slidably arranged on the guide rail 121. The guide rail 121 can also be supported by several support members 13. Among the two bases 31 of the flipping feeding device 3, the base 31 not provided with the flipping motor 35 is connected to the guide slider 122.

[0086] It can be understood that in this embodiment, the sliding table assembly 11 can serve as the active component for driving the flipping and feeding device 3 to slide, while the guide rail assembly 12 is the driven component synchronously driven by the flipping and feeding device 3. Specifically, in this embodiment, the sliding table 112 can be driven to slide on the slide rail 111 by the sliding motor 113. When the flipping and feeding device 3 slides, it synchronously drives the guiding slider 122 to slide on the guide rail 121, thereby achieving the purpose of driving the flipping and feeding device 3 to reciprocate between the clamping position and the detection position.

[0087] Of course, in some embodiments, two sets of sliding table assemblies 11 can also be provided. The two sets of sliding table assemblies 11 are respectively arranged on both sides in the width direction of the first clamping plate 32 and the second clamping plate 33, and the speeds of the two sets of sliding table assemblies 11 for driving the flipping and feeding device 3 to slide are kept synchronous.

[0088] Specifically, a blanking table 14 is arranged on the frame 1, and the feeding device 2 includes:

[0089] A storage mechanism 21, which is arranged on the blanking table 14 and is used for storing the wine boxes. The flat wine boxes are stacked in the storage mechanism 21 and keep a gap with the blanking table 14.

[0090] A material pulling mechanism 22, which is arranged below the blanking table 14 and is used for pulling the wine boxes in the storage mechanism 21 down to the blanking table 14 one by one; and

[0091] A material pushing mechanism 23, which is at least partially slidably arranged on the blanking table 14 and is used for pushing the wine boxes on the blanking table 14 onto the flipping and feeding device 3.

[0092] As Figure 1 and Figure 4 shown, in this embodiment, by way of example, the blanking table 14 is arranged inside the frame 1 and is located in the middle of the frame 1. It is arranged as a rectangular plate and is horizontally arranged. The length direction and width direction of the blanking table 14 are opposite to the length direction and width direction of the frame 1.

[0093] As Figure 5 and Figure 6 shown, the storage mechanism 21 is arranged on the blanking table 14 and is located in the middle of the width direction of the blanking table 14. The flat wine boxes are stacked in the storage mechanism 21, and there is a gap between the bottom of the stacked wine boxes and the blanking table 14, and this gap is not less than the maximum thickness of a flat wine box.

[0094] The material pulling mechanism 22 is arranged below the blanking table 14, and at least part of the material pulling mechanism 22 can pass through the blanking table 14 and extend into the material storage mechanism 21 to pull the wine boxes in the material storage mechanism 21 down onto the blanking table 14 one by one. It can be understood that the material pulling device is used to pull the wine boxes down one by one into the gap between the bottom of the stacked wine boxes and the blanking table 14.

[0095] The material pushing mechanism 23 is at least partially slidably arranged on the blanking table 14, and the sliding direction of the material pushing mechanism 23 is the length direction of the blanking table 14. At least part of the material pushing mechanism 23 is higher than the blanking table 14 to push the wine boxes on the blanking table 14 during the sliding process. In this embodiment, when the material pushing mechanism 23 slides, the part higher than the blanking table 14 extends into the gap between the bottom of the stacked wine boxes and the blanking table 14.

[0096] As Figure 2 and Figure 6 shown, it can be understood that when the feeding device 2 feeds the wine boxes into the flipping feeding device 3, it first drives the flipping feeding device 3 to move to the clamping position and makes both the first clamping plate 32 and the second clamping plate 33 keep horizontal. After the flipping feeding device 3 moves in place, its first clamping plate 32 is lower than the blanking table 14, and the second clamping plate 33 moves to a position higher than the blanking table 14 under the drive of the clamping cylinder 34. At the same time, the material pulling structure pulls the wine boxes in the material storage mechanism 21 down onto the blanking table 14 one by one, and the material pushing mechanism 23 pushes the wine boxes from the blanking table 14 to the first clamping plate 32. Subsequently, the second clamping plate 33 cooperates with the first clamping plate 32 under the drive of the clamping cylinder 34 to clamp and fix the wine boxes.

[0097] More specifically, the material storage mechanism 21 includes a pair of storage plates 211 arranged above the blanking table 14, a pair of limiting bottom plates 212 arranged between the pair of storage plates 211 and the blanking table 14, and a pressing block 213 vertically slidably arranged between the pair of storage plates 211. The pair of limiting bottom plates 212 are used to support the wine boxes, and the distance between the pair of limiting bottom plates 212 is less than the distance between the pair of storage plates 211. The pressing block 213 is used to press the stacked wine boxes onto the pair of limiting bottom plates 212.

[0098] As Figure 5 shown, in this embodiment, by way of example, a pair of storage plates 211 are arranged at intervals in the width direction of the blanking table 14, and the wine boxes are stacked longitudinally between the pair of storage plates 211. The mutually approaching sides of the pair of storage plates 211 are both vertically arranged to form abutting surfaces, and the two ends of the wine boxes in the width direction of the blanking table 14 respectively abut against the abutting surfaces of one storage plate 211.

[0099] A pair of material storage plates 211 are provided with reinforcing ribs 214 and reinforcing rods 215 for enhancing the structural strength of the material storage plates 211 on one side away from each other. The reinforcing ribs 214 can be arranged in a right-angle trapezoid shape and arranged horizontally. In the vertical direction, the reinforcing ribs 214 can be arranged at intervals in multiple rows, and four rows are arranged in this embodiment. The reinforcing rods 215 can be arranged in a square rod and arranged vertically to connect the two reinforcing ribs 214 located in the middle of the material storage plates 211 in the vertical direction.

[0100] like Figure 5 and Figure 7 As shown, in this embodiment, along the vertical direction, a pair of limiting bottom plates 212 are arranged between the material storage plates 211 and the material drop platform 14, and the pair of limiting bottom plates 212 are connected to the pair of material storage plates 211 in a one-to-one correspondence. Along the width direction of the material drop platform 14, the distance between the pair of limiting bottom plates 212 is smaller than the distance between the pair of material storage plates 211, so that when the wine boxes are stacked between the pair of material storage plates 211, the pair of limiting bottom plates 212 can support the wine boxes, thereby maintaining a gap between the bottom of the stacked wine boxes and the material drop platform 14.

[0101] The pressing block 213 is vertically slidably disposed between a pair of material storage plates 211 and is located above a pair of limiting bottom plates 212. It is understandable that the pressing block 213 can abut against the top of the stacked wine boxes to achieve the purpose of pressing and fixing the stacked wine boxes on the pair of limiting bottom plates 212. As the height of the stacked wine boxes gradually decreases, the pressing block 213 can gradually slide vertically downward under the action of its own weight and always press the stacked wine boxes.

[0102] More specifically, the material pulling mechanism 22 includes a suction cup 221 and a material pulling cylinder 222 connected to the suction cup 221 , and the material pulling cylinder 222 drives the suction cup 221 to pass through the drop table 14 to adsorb and pull down the wine box.

[0103] like Figure 6 and Figure 7 As shown, in this embodiment, the pulling cylinder 222 is exemplarily provided on the frame 1 and below the blanking platform 14. The suction cup 221 is connected to the piston end of the pulling cylinder 222 and moves vertically synchronously with the piston end of the pulling cylinder 222. The blanking platform 14 is provided with a clearance hole 141 on the vertical movement path of the suction cup 221, so that the suction cup 221 passes through the blanking platform 14 and extends between the two material storage plates 211, thereby adsorbing the stacked wine boxes.

[0104] It is understandable that when the suction cup 221 contacts the bottom of the stacked wine boxes, the lowest wine box in the stacked wine boxes can be sucked by the suction cup 221, and thereafter, the suction cup 221 moves vertically downward under the drive of the pulling cylinder 222, and pulls the lowest wine box down through the pair of limiting bottom plates 212, so that the wine box falls between the pair of limiting bottom plates 212 and the drop table 14. Then, the suction cup 221 can stop sucking air to separate from the wine box.

[0105] More specifically, the pushing mechanism 23 includes a pushing plate 231 slidably disposed on the blanking platform 14 and a pushing cylinder 232 connected to the pushing plate 231 . The top end of the pushing plate 231 is higher than the blanking platform 14 .

[0106] like Figure 6 and Figure 7 As shown, in this embodiment, the push cylinder 232 is exemplarily provided at one side of the bottom of the blanking platform 14, and its piston end is extended and retracted along the length direction of the blanking platform 14. The top of the push plate 231 passes through the blanking platform 14, that is, it is higher than the blanking platform 14, but it can be understood that the top of the push plate 231 is also lower than one side of a pair of limiting bottom plates 212 for supporting the stacked wine boxes. The bottom end of the push plate 231 is connected to the piston end of the push cylinder 232, so that the push plate 231 slides on the blanking platform 14 under the drive of the push cylinder 232.

[0107] like Figure 5 and Figure 7 As shown, the blanking table 14 is provided with a slide groove 142 along its length direction for pushing the plate 231 to slide. The slide groove 142 can be non-through-through arranged on the blanking table 14. At this time, one side of the pushing plate 231 passes through the side wall of the slide groove 142 to be connected with the piston end of the pushing cylinder 232. The clearance hole 141 for the suction cup 221 to pass through is arranged on the bottom of the slide groove 142 and passes through the bottom of the slide groove 142.

[0108] It can be understood that before the pulling mechanism 22 is actuated, the pushing cylinder 232 drives the pushing plate 231 to move to the side away from the blanking table 14 and away from the slide assembly 11; and when the pulling mechanism 22 pulls the wine box down to the blanking table 14, the pushing cylinder 232 drives the pushing plate 231 to slide in the direction close to the slide assembly 11, and the pushing plate 231 passes between a pair of limiting bottom plates 212, and pushes the wine box on the blanking table 14 into the flip feeding device 3 located at the clamping position of the slide assembly 11.

[0109] More specifically, the storage mechanism 21 further includes a storage adjustment component 216. The storage adjustment component 216 includes a pair of cooperating adjustment teeth 217 and an adjustment belt 218 disposed between the pair of adjustment teeth 217. The pair of storage plates 211 are respectively disposed on the upper side and the lower side of the adjustment belt 218 and move in opposite directions along the adjustment belt 218.

[0110] As Figure 5 and Figure 7 shown, in this embodiment, by way of example, a pair of adjustment teeth 217 are respectively rotatably disposed on two support plates 219. The support plates 219 can be configured as right trapezoids. The two support plates 219 are respectively disposed on one side of the pair of storage plates 211 away from each other and are connected to the blanking table 14. The adjustment belt 218 meshes with both the pair of adjustment teeth 217 and is tensioned. It includes an upper side and a lower side that are parallel to each other.

[0111] The pair of storage plates 211 are respectively connected to the upper side and the lower side of the adjustment belt 218 through two locking blocks 24. Specifically, the adjustment belt 218 is clamped between the two locking blocks 24, and at least one locking block 24 is connected to one end of the storage plate 211 along the length direction of the blanking table 14. The side of the two locking blocks 24 that clamps the adjustment belt 218 is provided with meshing teeth to enhance the friction force during locking and fixing.

[0112] As Figure 5 and Figure 7 shown, it can be understood that when driving one of the pair of storage plates 211 to move on the adjustment belt 218, the adjustment belt 218 moves and drives the pair of adjustment teeth 217 to rotate, and the adjustment belt 218 drives the other of the pair of storage plates 211 to move in the opposite direction to adjust the distance between the pair of storage plates 211. When the pair of storage plates 211 move, they synchronously drive the pair of limit bottom plates 212 to move, so that the storage mechanism 21 can be applicable to wine boxes of different widths, and the wine box vision detection system is applicable to the vision detection of wine boxes of various sizes.

[0113] It can also be understood that the pair of storage plates 211 move synchronously in opposite directions along the adjustment belt 218, and the distances during sliding can be kept consistent. Therefore, in this embodiment, the centering effect can be ensured when adjusting the distance between the pair of storage plates 211.

[0114] As Figure 5 and Figure 7As shown, in this embodiment, two guide rods 25 are further disposed between the two support plates 219, respectively above and below the adjustment belt 218, and both guide rods 25 extend along the width direction of the blanking table 14. The two ends of each storage plate 211 in the vertical direction are slidably disposed on the two guide rods 25 through an adjustment slider 251 respectively. Among the two adjustment sliders 251 on the same storage plate 211, at least one is fixed on the guide rod 25 by abutting against the guide rod 25 through a positioning screw 252; in this embodiment, the two adjustment sliders 251 on the guide rod 25 above the adjustment belt 218 are taken as an example. The positioning screw 252 passes through the adjustment slider 251 and is threadedly connected to the adjustment slider 251.

[0115] It can be understood that when driving the storage plate 211 to move on the adjustment belt 218, the storage plate 211 can synchronously drive the adjustment slider 251 to slide on the guide. Therefore, in this application, the sliding fit between the adjustment slider 251 and the guide rod 25 can improve the smoothness of the storage plate 211 during movement. After moving a pair of storage plates 211 in place, the adjustment slider 251 can be locked and fixed by the positioning screw 252, so as to achieve the purpose of maintaining the distance between a pair of storage plates 211.

[0116] As Figure 5 and Figure 7 shown, in this embodiment, the pressing block 213 is vertically slidably disposed on the pressing rod 26. The pressing rod 26 is vertically disposed and is connected to the two guide rods 25 through two support blocks 261 respectively. One end of the wine box along the length direction of the blanking table 14 can abut against the pressing rod 26, and one end of the wine box along the length direction of the blanking table 14 can be limited by the limiting side plate 27. There can be only one limiting side plate 27, which can be disposed on any one of the pair of storage plates 211, and the limiting side plate 27 is disposed at the end of the storage plate 211 away from the adjustment slider 251.

[0117] As Figure 5 shown, the limiting side plate 27 is slidably disposed on the storage plate 211. Specifically, it is connected to the adjusting rod 271, and the adjusting rod 271 extends along the length direction of the blanking table 14 and is slidably disposed on the reinforcing rod 215. Similarly, the adjusting rod 271 can be fixed by the positioning screw 252. At this time, the positioning screw 252 passes through one of the reinforcing rods 215 and is threadedly connected to the reinforcing rod 215. When the positioning screw 252 abuts against the adjusting rod 271, it can be locked and fixed.

[0118] It can be understood that in this application, the adjusting rod 271 is slidably disposed along the length direction of the blanking table 14, which can also make the storage mechanism 21 applicable to wine boxes of different lengths, so as to further improve the adaptability of the wine box vision detection system to the vision detection of wine boxes of various sizes.

[0119] Specifically, the blanking device 4 includes a material return mechanism 41 and a material collection mechanism 42 that are sequentially arranged below the flipping and feeding device 3. The material return mechanism 41 is used to receive the wine box clamped by the flipping and feeding device 3, and the material collection mechanism 42 is used to store the wine box.

[0120] As Figure 4 shown, in this embodiment, by way of example, the material return mechanism 41 is located above. After receiving the wine box clamped by the flipping and feeding device 3, it guides the wine box so that the wine box can fall into the material collection mechanism 42 located below and be stored by the material collection mechanism 42.

[0121] It can be understood that in this embodiment, the wine box after visual inspection is first received by the material return mechanism 41, and then stored by the material collection mechanism 42, which is convenient for neatly storing the wine box after visual inspection.

[0122] More specifically, the material return mechanism 41 includes a pair of material return plates 411 arranged below the blanking table 14, a sliding bottom plate 412 obliquely arranged between the pair of material return plates 411, and a conveyor belt 413 arranged at the lower end of the sliding bottom plate 412. One end of the conveyor belt 413 away from the sliding bottom plate 412 is close to the material collection mechanism 42.

[0123] As Figure 4 and Figure 9 shown, in this embodiment, by way of example, a pair of material return plates 411 are arranged at intervals and are arranged below the blanking table 14. A material return mounting plate 15 for installing the material return mechanism 41 is arranged below the blanking table 14. The material return mounting plate 15 and the blanking table 14 are supported by profile columns 16. Four profile columns 16 are provided and are respectively arranged at the four corners of the blanking table 14. A pair of material return plates 411 pass through the material return mounting plate 15 and extend vertically downward. One end of the pair of material return plates 411 close to the sliding table assembly 11 is arranged above the material return mounting plate 15 and is arranged in a flared shape, that is, one end of the pair of material return plates 411 close to the sliding table assembly 11 extends in a direction away from each other to guide the wine box after visual inspection, so as to facilitate receiving the wine box.

[0124] The sliding bottom plate 412 is obliquely arranged between the pair of material return plates 411, and it includes a high end located above and a low end located below. Among them, the high end of the sliding bottom plate 412 is located above the material return mounting plate 15 and is close to the sliding table assembly 11, while the low end is far from the sliding table assembly 11. In this embodiment, the inclination angle of the sliding bottom plate 412 is 30 degrees to be parallel to the first clamping plate 32 and the second clamping plate 33 when rotated to the qualified position or the unqualified position.

[0125] It can be understood that when the first clamping plate 32 and the second clamping plate 33 rotate to the qualified position or the unqualified position and release the clamping of the wine box, the wine box falls onto the sliding bottom plate 412 along the plate surface of the first clamping plate 32 or the second clamping plate 33 under the action of its own weight, and continues to fall along the plate surface of the sliding bottom plate 412 under the guidance of a pair of return plates 411.

[0126] As Figure 4 and Figure 9 shown, one end of the conveyor belt 413 is close to the lower end of the sliding bottom plate 412, and the other end is close to the receiving mechanism 42. In this embodiment, two sets of conveyor belts 413 can be provided and are respectively arranged on both sides in the width direction of the sliding bottom plate 412 for receiving the wine boxes falling along the plate surface of the sliding bottom plate 412 and conveying them into the receiving mechanism 42.

[0127] It can be understood that in this embodiment, a pair of return plates 411 and the sliding bottom plate 412 are used to receive the wine boxes after visual inspection, and the conveyor belt 413 is used to buffer their falling, so as to realize the guiding effect on the wine boxes, so that the wine boxes can move smoothly and accurately into the receiving mechanism 42 and be stored by the receiving mechanism 42.

[0128] As Figure 4 and Figure 9 shown, in this embodiment, a limiting plate 414 is provided at one end of a pair of return plates 411 close to the conveyor belt 413. The limiting plate 414 is arranged above the conveyor belt 413 and is arranged in one-to-one correspondence with the conveyor belt 413. When the conveyor belt 413 conveys the wine boxes, the two limiting plates 414 can limit and guide the wine boxes to further improve the accuracy of the conveyor belt 413 in conveying the wine boxes. It can be understood that when a pair of return plates 411 approach or move away from each other, the limiting plate 414 moves synchronously with the return plate 411 on the conveyor belt 413.

[0129] More specifically, the return mechanism 41 further includes a return adjustment assembly 415. The return adjustment assembly 415 includes a first drive disk 416, a first double-headed screw 417 rotatably arranged and connected to the first drive disk 416, and two return sliders 418 respectively threadedly connected to both ends of the first double-headed screw 417. The two return sliders 418 are connected to the first double-headed screw 417 in opposite directions, and a pair of return plates 411 are connected to the return sliders 418 in one-to-one correspondence.

[0130] As Figure 8As shown, in this embodiment, by way of example, the first double-headed screw 417 extends along the width direction of the blanking table 14 and is rotatably arranged on two profile beams 419. The two profile beams 419 are arranged on the side of a pair of return plates 411 away from each other, extend along the length direction of the blanking table 14, and both ends of each profile beam 419 are respectively connected to a profile column 16. Fixing blocks 43 for rotatably arranging the first double-headed screw 417 are arranged on both profile beams 419. The fixing blocks 43 are arranged in a cuboid shape, and the position where the first double-headed screw 417 is rotatably arranged is located in the middle of the length direction of the fixing blocks 43. The first driving disk 416 can be arranged at any end of the first double-headed screw 417 and is used to drive it to rotate.

[0131] Two return sliders 418 are respectively threadedly connected to both ends of the first double-headed screw 417, and the directions of the two return sliders 418 when threadedly connected to the first double-headed screw 417 are opposite. When the first double-headed screw 417 is driven to rotate by the first driving disk 416, the two return sliders 418 can be driven to move in opposite directions on the first double-headed screw 417, so as to move closer to or away from each other.

[0132] As Figure 8 shown, and a pair of return plates 411 are respectively connected to the return sliders 418 one by one, so that when the two return sliders 418 move, a pair of return plates 411 can be synchronously driven to move closer to or away from each other. In this embodiment, one side of the top of the return plate 411 extends out of the return mounting plate 15 and is connected to the return slider 418 through a connecting bracket 45. And the return mounting plate 15 is provided with an avoidance groove 151 along the width direction of the blanking table 14 to make way for the movement of a pair of return plates 411.

[0133] More specifically, two return slide rods 44 are also arranged in parallel between the two fixing blocks 43. The two return slide rods 44 are respectively arranged at both ends of the length direction of the fixing blocks 43, and the return sliders 418 are also slidably arranged on the two return slide rods 44. In this embodiment, the return slide rods 44 can guide the movement of the two return sliders 418, so that the movement of the return sliders 418 is more stable, and further achieve the purpose of driving a pair of return plates 411 to move closer to or away from each other stably and accurately.

[0134] It can be understood that when the width of the wine boxes stored in the storage mechanism 21 in the feeding device 2 is changed, the return mechanism 41 correspondingly adjusts the distance between a pair of return plates 411 through the return adjustment assembly 415 to receive the wine boxes with the changed width, so that the wine box vision detection device can meet the requirements for wine boxes of different sizes.

[0135] It can also be understood that in this embodiment, the distance between a pair of return plates 411 is adjusted by two return sliders 418 provided on the first double-headed screw 417, so that the pair of return plates 411 can move synchronously and the moving distances are kept consistent. Therefore, when adjusting the distance between the pair of return plates 411 in this embodiment, the centering effect of the pair of return plates 411 can always be maintained.

[0136] More specifically, the receiving mechanism 42 includes a receiving table 421 and two pairs of baffles 422 provided on the receiving table 421. Each pair of the baffles 422 is arranged oppositely and encloses a receiving space for storing the wine boxes.

[0137] As Figure 4 and Figure 10 shown, in this embodiment, by way of example, the receiving table 421 is arranged as a rectangle and is provided with a horizontal tabletop for placing and stacking the wine boxes. The two pairs of baffles 422 are vertically arranged on the receiving table 421, and each pair of the baffles 422 is arranged oppositely to limit the wine boxes. In this embodiment, the two pairs of baffles 422 are arranged in mutually perpendicular directions to respectively limit the two sides of the wine box in the length direction and the width direction. At this time, the cross-section of the enclosed receiving space is a rectangle and is adapted to the flat wine box. The sides of the baffles 422 away from the receiving table 421 can all be tilted and folded in a direction away from the receiving space, so that the wine boxes can more easily and accurately fall into the receiving space.

[0138] It can be understood that in this embodiment, the receiving space is enclosed by the receiving table 421 and the two pairs of baffles 422, so that the wine boxes can be neatly stacked in the receiving mechanism 42, and thus the receiving mechanism 42 has the advantages of simple structure and high space utilization rate; at the same time, when subsequently selecting unqualified defective wine boxes in a way that distinguishes the heads and tails of the wine boxes, it can also be more convenient and fast.

[0139] More specifically, the receiving mechanism 42 further includes two sets of receiving adjustment components 423 corresponding to each pair of the baffles 422. The receiving adjustment component 423 includes a second driving disk 424, a second double-headed screw 425 rotatably arranged and connected to the second driving disk 424, and receiving sliders 426 respectively threadedly connected to the two ends of the second double-headed screw 425. The two receiving sliders 426 are connected to the second double-headed screw 425 in opposite directions, and at least one of a pair of the baffles 422 is arranged on one of the receiving sliders 426 of a set of the receiving components corresponding to the pair of the baffles 422.

[0140] As Figure 10As shown, in this embodiment, by way of example, the receiving adjustment assembly 423 is arranged below the receiving table 421, and its structure and principle are the same as those of the return material adjustment assembly 415. Among them, the second double-headed screw 425 can be rotatably arranged on two J-shaped frames 427, and two receiving slide bars 428 can be arranged in parallel between the two J-shaped frames 427, and two receiving sliders 426 are slidably arranged on the two receiving slide bars 428, so that the sliding of the receiving sliders 426 is smoother. The receiving sliders 426 can be connected to the outer side wall of the baffle 422 through a bent bracket 429 to synchronously drive the baffle 422 to move.

[0141] It can be understood that a set of receiving adjustment assemblies 423 can be arranged along the length direction and the width direction of the receiving table 421 respectively, and are arranged in one-to-one correspondence with two pairs of baffles 422. And along the width direction of the blanking table 14, a pair of baffles 422 can be respectively connected to the two receiving sliders 426 of the corresponding receiving adjustment assembly 423, so that the pair of baffles 422 can move simultaneously, so that the receiving mechanism 42 is applicable to wine boxes of different widths. And along the length direction of the blanking table 14, only one of a pair of baffles 422 can be connected to one of the receiving sliders 426 of the corresponding receiving adjustment assembly 423, so that only one of the pair of baffles 422 moves, and the receiving mechanism 42 is applicable to wine boxes of different lengths. Of course, in some embodiments, the connection methods in the aforementioned length direction and width direction can be interchanged.

[0142] In this embodiment, the distance between the two pairs of baffles 422 can be adjusted respectively through the receiving adjustment assembly 423, so that the receiving mechanism 42 can receive wine boxes of different widths and different lengths. Therefore, this embodiment can enable the wine box vision detection device to meet the requirements for wine boxes of different sizes.

[0143] The implementation principle of an embodiment of this application is as follows:

[0144] During specific detection, first adjust the storage mechanism 21, the return material mechanism 41 and the receiving mechanism 42 according to the width size and length size of the wine box to be visually detected.

[0145] When adjusting the storage mechanism 21, first loosen the positioning screw 252, and drive any one of the storage plates 211 to move on the adjustment belt 218. When the storage plate 211 moves, the adjustment belt 218 moves and drives a pair of adjustment teeth 217 to rotate, and the adjustment belt 218 drives the other of the pair of storage plates 211 to move in the opposite direction to adjust the distance between the pair of storage plates 211, and when the pair of storage plates 211 move, they synchronously drive a pair of limit bottom plates 212 to move; at the same time, the storage plate 211 can synchronously drive the adjustment slider 251 to slide on the guide to make the movement of the storage plate 211 smoother.

[0146] When adjusting the return material mechanism 41, the first double-headed screw 417 is driven to rotate by the first driving disk 416, so as to drive the two return material sliders 418 to move in opposite directions along the first double-headed screw 417. When the return material sliders 418 move, they synchronously drive a pair of return material plates 411 to approach or move away from each other, so as to be applicable to wine boxes of different widths.

[0147] When adjusting the material receiving mechanism 42, the second double-headed screw 425 is driven to rotate by the second driving disk 424, so as to drive the two material receiving sliders 426 to move in opposite directions along the second double-headed screw 425. When the material receiving sliders 426 move, they synchronously drive a pair of baffle plates 422 to approach or move away from each other. By respectively adjusting the two groups of material receiving adjusting components 423 along the length direction and the width direction of the material receiving table 421, the material receiving mechanism 42 can be made applicable to wine boxes of different lengths and different widths.

[0148] After adjusting the storage mechanism 21, the return material mechanism 41 and the material receiving mechanism 42, stack the flat wine boxes between a pair of storage plates 211, and adjust the position of the limiting side plates 27 on the storage plates 211, so as to limit the two sides in the length direction of the wine boxes through the limiting side plates 27 and the pressing material slide rods 26. Then press and fix the stacked wine boxes on a pair of limiting bottom plates 212 through the pressing blocks 213. Then drive the piston end of the material pulling cylinder 222 to extend, so that the suction cup 221 passes through the blanking table 14 and extends between a pair of storage plates 211, and the lowest wine box in the stacked wine boxes can be adsorbed by the suction cup 221. After that, the suction cup 221 moves vertically downward under the drive of the material pulling cylinder 222, and pulls down the lowest wine box through a pair of limiting bottom plates 212, so that the wine box falls between a pair of limiting bottom plates 212 and the blanking table 14. Subsequently, the suction cup 221 can stop sucking air to separate from the wine box. At the same time, drive the flipping feeding device 3 to move to the clamping position, and make both the first clamping plate 32 and the second clamping plate 33 keep horizontal, and then make the second clamping plate 33 move to a position higher than the blanking table 14 under the drive of the clamping cylinder 34. Then drive the pushing plate 231 to slide along the direction close to the sliding table assembly 11 through the pushing cylinder 232. The pushing plate 231 passes through between a pair of limiting bottom plates 212, and pushes the wine box on the blanking table 14 to the first clamping plate 32 located at the clamping position of the sliding table assembly 11. Subsequently, the second clamping plate 33 cooperates with the first clamping plate 32 under the drive of the clamping cylinder 34 to clamp and fix the wine box.

[0149] After the wine box is clamped and fixed, the two bases 31 of the flipping and feeding device 3 are driven to slide on the sliding table assembly 11, so as to synchronously move the wine box clamped between the first clamping plate 32 and the second clamping plate 33 to the detection position. At the detection position, the wine box is visually inspected by the vision inspection device. After the vision inspection device visually inspects the wine box, the two bases 31 of the flipping and feeding device 3 move the wine box back to the clamping position, and then the flipping motor 35 rotates the first clamping plate 32 and the second clamping plate 33 to the qualified position or the unqualified position according to the inspection result of the vision inspection device.

[0150] After the first clamping plate 32 and the second clamping plate 33 rotate in place, the clamping cylinder 34 drives the second clamping plate 33 to move away from the first clamping plate 32 again to release the clamping of the wine box. The wine box falls onto the sliding bottom plate 412 along the plate surface of the first clamping plate 32 or the second clamping plate 33 under the action of its own weight, and continues to fall onto the conveyor belt 413 along the plate surface of the sliding bottom plate 412 under the guidance of a pair of return plates 411, and then is conveyed by the conveyor belt 413 to the storage space enclosed by the two pairs of baffles 422 for storage. During storage, the flat wine boxes are stacked in the storage space.

[0151] This application can realize the visual inspection of flat wine boxes, and can further prepare the qualified flat wine boxes into a three-dimensional shape after visual inspection. Compared with the visual inspection of three-dimensional wine boxes, this application can avoid unnecessary preparation processes for unqualified defective wine boxes, thereby achieving the purpose of cost saving.

[0152] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0153] The above-described embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
