Specifically, it is a set of several parts composed of a containerized height-changing and adjustment component for adjusting the fixed state and posture of a visual positioning manipulator of a gift box machine. Background Art

[0002] Gift box is a kind of packaging method that is an extension of social needs. Gift box machine is a kind of equipment specially used for producing gift box packaging. It can customize the size, shape, material and printing pattern of gift boxes according to customer needs to meet the needs of different occasions. This machine plays an important role in gift packaging, gift-giving occasions and business promotions.

[0003] Gift box machines are widely used in gift box packaging in the food, beverage, cosmetics, pharmaceutical and other industries. For example, in the food industry, they can be used to package gift boxes such as cakes, candies, and chocolates; in the cosmetics industry, they can be used to package cosmetic gift boxes; at the same time, they are also suitable for business promotions and holiday gift giving. The main types and functions of gift box machines include but are not limited to:

[0004] Printing machine is one of the indispensable equipment in the production of gift boxes. Printing machine is used to print gift boxes to improve the appearance quality and market competitiveness of gift boxes. Commonly used printing methods include offset printing, letterpress printing, flexographic printing, etc.

[0005] Gift box heat shrink packaging machine: Use heat shrink film to pack gift boxes. By heating, the heat shrink film shrinks and fits tightly to the surface of the gift box, improving packaging efficiency and aesthetics.

[0006] Automatic gift box packaging machine: It can automatically complete the gift box packaging process, including laminating, die-cutting and other steps, reduce labor costs, and improve production efficiency and packaging quality.

[0007] Laminating machine: Laminating the surface of gift boxes to increase the wear resistance, waterproofness and anti-pollution properties of gift boxes.

[0008] Die-cutting machine: Cut paper or cardboard into gift boxes of the desired shape. It can cut gift boxes of various shapes, such as square, round, heart, etc.

[0009] When using traditional automatic shapers for gift box production, the shape of gift boxes is usually limited to the maximum size. For example, the TS-460D1 high-speed fully automatic top and bottom box shaper is an automated equipment for high-precision positioning of boutique boxes. This unit consists of a set of visual positioning shaping lines consisting of various facial papers for gluing visual positioning, fully automatic corner pasting machines, and shaping manipulators. It is suitable for mass production of various box types, such as gift boxes, packaging boxes, handmade boxes, etc. However, the maximum length and width of the box shape cannot exceed 400*400*mm, and the height of the box shape is 18-120mm, which is ultimately subject to the unfolded size of the facial paper; the maximum facial paper size is 880*560mm, the minimum facial paper size is 140*140mm, and the positioning accuracy is: ±0.05mm.

[0010] There are limited relevant documents that have been published. For example, patent application No. 202023027449.7 discloses a fully automatic forming device for gift box production, patent application No. 202320165038.9 discloses a high-precision automatic positioning manipulator for cardboard gluing machine, patent application No. 202022397865.X discloses an automated equipment for producing high-quality gift boxes, and patent application No. 201911208258.X involves a gift box production equipment, etc.

[0011] This type of equipment is commonly used now, including conveyor belts, paper loading mechanisms, gluing mechanisms, box loading mechanisms, primary forming mechanisms and complete forming mechanisms, and most of them adopt automated control. Although it can free people from heavy physical labor, some mental labor, and harsh and dangerous working environments, greatly improve labor productivity and product quality, production parameters and system structural components are not allowed to be changed at will. This leads to inconveniences in gift box production and seriously affects the user experience, which urgently needs to be improved. Utility Model Content

[0012] The technical problem to be solved by the utility model is that the existing equipment has strict requirements on the maximum production size of processable products, so that some small amounts of products with length, width or height exceeding the standard size cannot be processed.

[0013] In view of the above problems and technical requirements, the utility model proposes a gift box machine product height adjustment component to solve the above existing problems in a low-cost, simple and effective manner, that is, to solve the problem that the traditional gift box production automatic former can relax the production of small-sized and over-limit products when in use.

Alternatively, the edge of the side stop bracket has a limiting slope groove toward the surface of the container board, the limiting slope groove is V-shaped, and the angle between its two side walls is greater than 30°. There can be 1 to 3 slide grooves.

[0017] At least one connecting rod is arranged on the container board, and the connecting rod passes through the pad through the air connection hole, and then the end of the connecting rod is pressed on the limiting slope groove or limiting straight groove. The middle part of the connecting rod passes through the corresponding opening of the upper section of the plug-in rod to further position the pad; or, the connecting rod is blocked by the plug-in rod inserted into the array mesh in the middle to limit the position; or, the middle section of the connecting rod is pressed on the upper side of the pad placed in the middle to prevent shaking. Furthermore, the surface of the plug-in rod or the connecting rod is covered with a rubber sleeve, sprayed with glue or flocked.

[0038] It should be noted that:

[0039] The terms "comprise", "comprises", "having" and any variations thereof are intended to cover other possible options under the same logic that are not listed. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products or apparatus.

[0040] In the description of the present utility model, the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In order to enable those skilled in the art to better understand the scheme of the utility model, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only an embodiment of a part of the utility model, rather than all the embodiments.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by ordinary technicians in the field to which the utility model belongs. When there is a conflict, the definitions in this specification shall prevail.

[0044] The principle of the utility model is that the parameters of multiple links in the gift box machine automation equipment actually jointly limit the production size of the product. However, on the one hand, most of the components and structures cooperate closely with each other and the coordination relationship is complex, making it difficult to simply achieve the required production parameter adjustments. On the other hand, the widespread application of IoT remote management and technical support also strictly restricts the user from dismantling the equipment without authorization. The study found that only as the visual positioning link in the gift box production process, due to the existence of a large fault-tolerant configuration of the equipment design logic itself, in this link, when the working mechanism of the positioning manipulator mounting seat is replaced as permitted in the operating manual, a pad component with a gasket structure is added, so that the implicit adjustable range is explicitly enlarged, and ultimately a limited expansion adjustment of the maximum size of the processable product is obtained.

[0045] In the utility model, since the improved pad component requires high precision and involves great economic value, it is necessary to design a special container device to reasonably store and maintain it.

[0046] The utility model comprises: a backing plate 14 and a container plate 20.

[0047] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0048] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.

[0050] Among them, the process of visual positioning robot 8 is more critical. In this process, at least two parts need to be accurately positioned and assembled together. The permitted production parameters of the product are only independently defined and restricted here.

[0051] For example, see Attachment Figure 2 As shown, a fixing frame 82 with a rotating clamping structure is fixed to the end of the three-axis forearm 81 of the visual positioning manipulator 8, and a fixing seat 84 is clamped and connected to the fixing frame 82; it can be seen that the fixing seat 84 usually has a connecting plate component with multiple evenly arranged mounting holes.

[0052] Reference Figure 3 As shown, the end of the three-axis forearm 81 of the visual positioning robot 8 is connected to a fixing frame 82 having a switching structure with bolt fastening components, and a cylinder 83 is installed on at least two side edges of the fixing frame 82, and the front end of the cylinder 83 is connected to a fixing seat 84 through a piston rod; similarly, the fixing seat 84 has a connecting plate component with a plurality of evenly arranged mounting holes.

[0053] For further information, see Attachment Figure 4 As shown, on the fixing seat 84, the slide 16 is fixed through the mounting hole with the first fastening bolt 15. There is a slide groove in the longitudinal middle of the slide 16, and the first adjusting bolt 17 is connected and fixed to the backing plate 14 in the slide groove; obviously, there is an air connection hole 142 in the middle of the front end of the backing plate 14, and a slide groove 141 is opened from the middle to the rear end of the backing plate 14. The first adjusting bolt 17 is inserted into the slide groove 141, and the nut of the first adjusting bolt 17 is tightened after adjustment to stabilize the backing plate 14. Next, the air line of the suction nozzle 18 is inserted into the air connection hole 142 and fixed.

[0054] The content of the present invention can be more easily understood by selecting the following preferred implementation methods and embodiments of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by ordinary technicians in the field to which the present invention belongs. When there is a conflict, the definition in this specification shall prevail.

[0055] Embodiment 1: The backing plate 14 is positioned and limited on the container plate 20; as shown in the attached Figure 5 As shown, multiple groups of array meshes 201 arranged in a dot matrix are evenly arranged in the middle of the container board 20, and a side stop bracket 202 is erected and fixed perpendicular to the surface of the container board 20 on at least one side edge of the container board 20; a slot structure is opened on the side stop bracket 202.

[0056] In the above, the length and width of the pad 14 can be designed into various specifications as needed. In addition, preferably, the chute 141 can be 1 to 3.

[0057] In the above description, the container plate 20 is a rectangular flat plate according to the usual design. The side stop bracket 202 is a flat plate structure, and its top edge is parallel to the surface of the container plate 20 .

[0058] In the above, the pad 14 is inserted into the array mesh 201 through the plug rod 21 through the air receiving hole 142. In addition, a second plug rod 21 can be used to pass through the slide slot 141 and be inserted into the array mesh 201 to further stabilize the pad 14.

[0059] In the above, the edge of the side stop bracket 202 opens a limiting straight groove 2022 toward the surface of the container board 20, and the limiting straight groove 2022 is perpendicular to the surface of the container board 20, or extends obliquely into the side stop bracket 202. Alternatively, the edge of the side stop bracket 202 opens a limiting slope groove 2021 toward the surface of the container board 20, and the limiting slope groove 2021 is V-shaped, and the angle between its two side walls is greater than 30°.

[0060] In the foregoing, as attached Figure 6 As shown, at least one pad 14 is passed through the air connection hole 142 by the connecting rod 22, and then the end of the connecting rod 22 is pressed on the limiting slope groove 2021 or the limiting straight groove 2022. In addition, the use method of the connecting rod 22 can also include, first, passing through the corresponding opening in the upper section of the plug-in rod 21 to further position the pad 14, second, blocking it next to the plug-in rod 21 erected in the middle to limit it, and third, pressing it on the upper side of the pad 14 placed in the middle to prevent shaking. Furthermore, the surface of the plug-in rod 21 or the connecting rod 22 is covered with a rubber sleeve, sprayed with glue or flocked to reduce or avoid damage to the inner wall of the docking air hole 142. Furthermore, a polyurethane vibration damping layer is provided on the upper surface of the container plate 20 to protect the workpiece.

[0061] In the embodiment of the utility model, as shown in the attached Figure 7 As shown, the periphery of the air receiving hole 142 of the backing plate 14 is axially protruding while the remaining portion has a uniform thickness. The periphery thickness of the air receiving hole 142 is at least greater than 30% of the average thickness of the backing plate 14 .

[0062] In the embodiment of the utility model, as shown in the attached Figure 8 As shown, two backing plates 14 with the same structure are reversely buckled and then connected by bolts. Two thickness effects can be obtained, namely, one is as shown in the figure, the air receiving hole 142 of one backing plate 14 corresponds to the slide groove 141 of the other backing plate 14, and the other is to align and connect only the slide grooves 141 of the two backing plates 14. Obviously, the total combined thickness of the former is greater than that of the latter.

[0063] The implementation principle of this embodiment is: similar pads 14 of various structures and sizes are stored on the container plate 20. These pads 14 are measured and tested, and then the corresponding parameters of their respective adjustment effects are summarized and marked for standby use, which is convenient and easy to use when needed.

[0064] Embodiment 2: As attached Fig. 9 As shown, at least one side surface of the pad 14 is thinned and inclined from the air receiving hole 142 to the other end, and the thickness of the periphery of the air receiving hole 142 is at least greater than 30% of the average thickness of the pad 14 .

[0065] When applying, as attached Fig.10 As shown, in order to ensure the application effect, a rubber surface or a rough surface is provided on the inclined surface of the backing plate 14, and a friction pad 19 is sandwiched between the two inclined surfaces. After adjusting to the required total thickness to overcome the contact interface sliding, the first adjusting bolt 17 is inserted and tightened. Then the aforementioned connection and installation are performed.

[0066] Preferably, the friction pad 19 is a polyurethane pad, a sandpaper disc, or even a non-woven fabric to enhance the friction coefficient of the contact interface.

[0067] The implementation principle of this embodiment is as follows: Hongming visual positioning machine or visual positioning line dual-use TS-650-SY is an automated equipment for high-precision positioning of high-quality boxes. The characteristics of this model are that it can produce both skins and box blanks, meeting various needs of the industry, and is suitable for gluing with various surface papers and precise positioning of skins and box blanks. It can be freely used with fully automatic corner pasting machines, semi-automatic forming machines, forming robots, and four-sided edge machines. The positioning module is independent, and the fully intelligent automatic visual positioning adopts a servo human-machine interface control system and an image positioning system. Paper feeding, gluing, and positioning are automatically completed. The accuracy is ±0.05mm. The original machine has a maximum box-making size of 130 mm in height. On the fixed seat 84 at the end of the three-axis forearm 81 of the visual positioning manipulator 8, the improved pad 14 of the embodiment of the utility model is used, that is, on the fixed seat 84, four 10 mm thick pads 14 are added, or a 40 mm thick pad 14 is replaced, or a pair of thick pads 14 that cooperate with each other and can be adjusted to a total thickness of 40 mm are installed, so that the height is limitedly increased, and the maximum size height is enlarged to 138 mm after the improvement. After the improvement, gift boxes with a height of 138 mm can be produced. The adjustment steps include:

[0068] Stop the machine and disconnect the power supply: Before making any mechanical adjustments, the gift box machine must be stopped and the relevant power supply must be disconnected to ensure safe operation.

[0069] Dismantle the original components: Depending on the height that needs to be adjusted, it may be necessary to dismantle some of the original components, such as molds, guide rails, etc.

[0070] Install new components: Install new components according to the new height requirements of the product. This may include new molds, guides, sensors, etc.

[0071] Debugging and testing: After installation, the gift box machine needs to be debugged and tested to ensure that it operates normally and meets the new height requirements.

[0072] Based on the above embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention, so as to avoid exhaustively listing all implementation methods that are unnecessary and impossible to list comprehensively.
