Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material processing equipment, specifically relating to a robotic arm for assembling the edge strip of a top-opening wine box. Background Technology

[0002] like Figure 3 As shown, the edge strip 5 of the wine box refers to a U-shaped or L-shaped strip of material that is pasted on the inner edge of the wine box opening. Its main function is to support and position the wine box lid from the inside, making the lid close more accurately and less prone to deformation. Existing automated installation processes typically include: applying adhesive to the wine box opening, then using a robotic arm to pick up the edge strip and transport it to a predetermined position inside the wine box, and finally using a clamping mechanism to press the edges of the strip firmly against the inner wall of the wine box.

[0003] However, with changing consumption trends in the beverage market, small and medium-sized wineries are increasingly shifting their orders towards personalized customization with more varieties and smaller batches. Existing assembly robots typically use fixed-size suction molds that cannot be adjusted. Therefore, when faced with different sizes of wine boxes, manufacturers must customize and replace the corresponding suction molds for each size. This not only increases production line downtime but also significantly raises equipment investment and maintenance costs for enterprises. Therefore, developing a robot for assembling the mouth rim strips that can adapt to different wine box sizes and eliminates the need for frequent mold changes has become a pressing problem in this field. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a top-opening wine box edge strip assembly robot. This robot can flexibly adapt to wine box edge strips of different sizes without the need to customize special molds for each specification, thereby reducing equipment costs and improving production flexibility.

[0005] The objective of this utility model can be achieved through the following technical solution: a robotic arm for assembling the side panel of a top-opening wine box, characterized in that the robotic arm comprises:

[0006] A first mounting plate, the lower surface of which is fixed with a first slide rail running in a front-to-back direction, a first slide table slidably connected on the first slide rail, and a first cylinder fixed on the first mounting plate that can drive the first slide table to slide along the first slide rail.

[0007] The second mounting plate is fixed to the lower surface of the first slide table. A second slide rail running vertically is fixed on the second mounting plate. A second slide table is slidably connected on the second slide rail. A second cylinder that can drive the second slide table to slide along the second slide rail is fixed on the second mounting plate.

[0008] The third slide rail is fixed to the second slide platform and its direction is left and right. The third slide rail is slidably connected to the third slide platform and the fourth slide platform.

[0009] A double-ended lead screw is rotatably connected to the second mounting plate. The two ends of the double-ended lead screw are threadedly connected to the third slide and the fourth slide respectively, and the threads at the two ends of the double-ended lead screw are in opposite directions. A rotating handle is fixed to one end of the double-ended lead screw. By rotating the rotating handle, the third slide and the fourth slide can be driven to move synchronously towards or away from each other along the third slide rail to adjust the distance between them.

[0010] An adsorption block is fixed at the bottom of the third and fourth slides respectively; an adsorption groove is provided on the front end of each adsorption block on its outer side wall and bottom surface.

[0011] A recessed suction cup is provided in each of the aforementioned suction grooves;

[0012] Negative pressure connectors are provided on each of the adsorption blocks, and each negative pressure connector is connected to all the sinking suction cups located on the same adsorption block.

[0013] Preferably, on the same adsorption block, the angle between the adsorption groove on its outer wall and the adsorption groove on the bottom surface is between 75 degrees and 85 degrees.

[0014] The advantages of this utility model are:

[0015] 1. High versatility: This robotic arm uses a double-ended screw with a rotating handle to adjust the left and right distance between the two adsorption blocks, making it compatible with various sizes of wine box edge strips. This changes the traditional "one box, one mold" model and achieves compatibility with various sizes of wine box edge strips.

[0016] 2. Stable Adsorption and Precise Positioning: The adsorption block features L-shaped, recessed suction cups arranged at a specific angle (75°-85°), which can simultaneously and firmly adhere to both the outer vertical and bottom surfaces of the rim strip. This design not only provides a stable gripping force, preventing displacement during handling, but also allows the rim strip to slightly retract when inserted into the wine box, reducing interference with the box opening and thus improving the accuracy and smoothness of installation.

[0017] 3. Improve efficiency and reduce costs: When faced with customized orders of multiple varieties and small batches, there is no need to frequently stop the machine to change molds. Only simple adjustments are needed to put it into production, which significantly improves the flexibility and production efficiency of the production line, while greatly reducing the company's mold equipment investment costs.

[0022] The following are specific embodiments of the present invention, described in conjunction with the accompanying drawings, to further illustrate the technical solution of the present invention. However, the present invention is not limited to these embodiments. It should also be noted that directional terms used in this specification, such as "front," "back," "up," "down," "left," and "right," are defined based on the directions shown in the accompanying drawings or the usual placement of components, and are merely for ease of description and should not be construed as limiting the present invention.

[0023] like Figure 1 , Figure 2 As shown, a robotic arm for assembling the edge strip of a top-opening wine box is characterized in that the robotic arm comprises:

[0024] A first mounting plate 1, with a first slide rail 11 running in a front-to-back direction fixed on its lower surface, a first slide table 12 slidably connected on the first slide rail 11, and a first cylinder 13 fixed on the first mounting plate 1 that can drive the first slide table 12 to slide along the first slide rail 11.

[0025] The second mounting plate 2 is fixed to the lower surface of the first slide table 12. The second mounting plate 2 is fixed with a second slide rail 21 running vertically. The second slide rail 21 is slidably connected to the second slide table 22. The second mounting plate 2 is also fixed with a second cylinder 23 that can drive the second slide table 22 to slide along the second slide rail 21.

[0026] The third slide rail 3 is fixed on the second slide table 22 and its direction is left and right. The third slide rail 3 is slidably connected to the third slide table 31 and the fourth slide table 32.

[0027] A double-ended lead screw 33 is rotatably connected to the second mounting plate 2. The two ends of the double-ended lead screw 33 are threadedly connected to the third slide 31 and the fourth slide 32 respectively, and the threads at the two ends of the double-ended lead screw 33 have opposite directions. A rotating handle 34 is fixed to one end of the double-ended lead screw 33. By rotating the rotating handle 34, the third slide 31 and the fourth slide 32 can be driven to move synchronously towards or away from each other along the third slide rail 3 to adjust the distance between them.

[0028] Adsorption block 4, an adsorption block 4 is fixed at the bottom of the third slide 31 and the fourth slide 32 respectively; an adsorption groove 41 is provided on the front end of each adsorption block 4 on its outer side wall and bottom surface;

[0029] A recessed suction cup 42 is provided in each of the adsorption grooves 41;

[0030] Negative pressure pipe 43 is provided on each of the adsorption blocks 4, and each negative pressure pipe 43 is connected to all the sinking suction cups 42 located on the same adsorption block 4.

[0031] Working principle:

[0032] (1) Adjusting the machine: We can refer to the size of the mouth edge strip and turn the double-headed screw 33 by rotating each handle 34 to adjust the distance between the two adsorption blocks 4 so that the adsorption groove 41 on the two adsorption blocks 4 matches the inner outer dimensions of the wine box mouth edge strip.

[0033] (2) Material picking: Start the assembly process of the wine box mouth edge strip. The wine box mouth edge strip is first sent to the feeding position by the push plate. Then, the second cylinder 23 extends outward, driving the second slide table 22 to move down, so that the two adsorption blocks 4 contact the wine box mouth edge strip. At the same time, the vacuum system is started, and each sinking suction cup 42 generates negative pressure. The two adsorption blocks 4 adsorb the wine box mouth edge strip together. Then, the second cylinder 23 retracts and lifts the wine box mouth edge strip to complete the material picking.

[0034] (3) Feeding: The first cylinder 13 extends outward, driving the first slide 12 to move forward, so that the two adsorption blocks 4 with the mouth edge strips extend into the opening of the wine box to complete the feeding operation.

[0035] (4) Assembly: When the wine box mouth edge strip 5 reaches above its assembly position, the second cylinder 23 extends outward again, so that the bottom surface of the wine box mouth edge strip 5 contacts and adheres to the inner side wall of the wine box, thus completing the assembly of the wine box mouth edge strip 5.

[0036] (5) Mold assembly reset: After the assembly of one edge strip is completed, the first cylinder 13 and the second cylinder 23 move in opposite directions, so that the entire robot returns to the top of the feeding position.

[0037] In this robotic arm, the lateral distance between the two suction blocks 4 is adjusted via a double-ended lead screw 33 with a rotating handle 34, allowing it to adapt to various sizes of wine box edge trim 5. This changes the traditional "one box, one mold" approach and enables compatibility with multiple sizes of wine box edge trim 5. Simultaneously, the suction blocks 4 are equipped with L-shaped recessed suction cups 42, which can firmly adhere to both the vertical and bottom surfaces of the edge trim, forming a stable grip and effectively preventing the trim from shifting or falling off during handling and installation, thus ensuring accurate installation positioning.

[0038] like Figure 2 and Figure 3 As shown, on the same adsorption block 4, the angle between the adsorption groove 41 on its outer wall and the adsorption groove 41 on its bottom surface is between 75 and 85 degrees. Since the outer dimensions of the box opening strip must be very close to the opening of the wine box, this acute angle design causes the vertical surfaces on both sides of the box to contract when the box opening strip 5 is adsorbed, thus reducing the obstruction when it is sent into the wine box and further improving its installation accuracy. At the same time, the recessed suction cup 42 can better fit the L-shaped or U-shaped bend of the opening strip, providing a more stable and reliable adsorption force.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
