Description

Technical Field

[0001] The invention mainly relates to the technical field of iron can processing, and in particular to a can pressing device for high-precision metal iron can processing. Background Art

[0002] With the vigorous development of modern industry and the increasing requirements of the consumer market for product packaging quality, metal cans, as an important packaging container, are widely used in many fields such as food, beverages, cosmetics, and chemical products. Metal cans are favored by various industries because of their good sealing, barrier properties, mechanical strength, and aesthetics. However, the market's quality and precision standards for metal cans are becoming more and more stringent. Not only do they require the cans to have a regular shape and a smooth and flawless surface, but also in terms of dimensional accuracy, parameters such as can diameter, height, and wall thickness need to be strictly controlled within a very small tolerance range to meet the adaptation requirements of the automated filling production line, improve product display effects, and ensure product storage and transportation safety. For example, in the cosmetics industry, exquisite and compact metal can packaging often requires high-precision processing to show the high-end image of the brand. Even a small dimensional deviation or appearance defect may affect the overall quality and market competitiveness of the product; the food industry also has high requirements for the sealing and dimensional accuracy of cans. Precise processing helps to extend the shelf life of food and ensure that the product meets hygiene standards.

[0003] Most traditional metal can processing and pressing equipment adopts fixed mold installation. Once the position of the mold on the equipment is determined, it is difficult to flexibly adjust it. When it is necessary to process cans of different specifications (such as different sizes and shapes), the mold needs to be replaced, but the positioning accuracy of the mold after reinstallation is difficult to guarantee, and it is easy to have inaccurate upper and lower molds. This leads to uneven force on the metal sheet during the stamping process, and the produced cans will have quality problems such as uneven wall thickness, irregular shape, large size deviation, etc., which cannot meet the high-precision processing requirements.

[0004] The quality inspection of metal cans after processing mostly relies on manual visual inspection and simple measuring tools. Manual visual inspection is prone to missed inspections and misjudgments, and it is difficult to accurately identify some minor appearance defects (such as minor scratches, shallow pits, etc.). Moreover, this traditional inspection method is extremely inefficient and cannot adapt to the rhythm of large-scale and rapid production. It often causes unqualified products to be mixed into finished products, affecting the overall quality of the product. At the same time, it may also reduce production efficiency due to frequent rework and other operations.

[0005] The traditional metal can processing production line is not closely connected between the various links, the degree of automation is insufficient, and there are many manual operation links, such as loading and unloading, mold adjustment, and material transfer between different processing steps, which mostly rely on manual handling and operation. This not only increases labor costs, but also easily leads to low production efficiency and unstable product quality due to human factors (such as operating errors, fatigue, etc.), making it difficult to achieve continuous, efficient and high-precision mass production of metal cans, and unable to meet the needs of modern industry for large-scale, high-quality can production.

[0014] 3. Beneficial effects: Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention can accurately adjust the positions of the upper die and the lower die in multi-axis directions (X-axis, Y-axis, Z-axis) through the first position adjustment mechanism, the second position adjustment mechanism and the third position adjustment mechanism, so as to adapt to the processing requirements of iron cans of different sizes and shapes, ensure that the upper die and the lower die can be accurately matched before each stamping, ensure the accuracy of the stamping action, thereby realizing high-precision control of the size and shape of each part of the iron can and improving the molding quality of the product.

[0015] The hydraulic cylinder in the can pressing mechanism of the present invention provides stable and adjustable stamping power, and cooperates with the precise guidance of the guide column and the buffering effect of the spring to make the stamping process smooth and uniform, which can not only ensure that the metal plate or semi-finished product is smoothly deformed according to the requirements of the mold, but also avoid product defects caused by problems such as excessive impact force or inaccurate mold closing, achieve high-quality stamping and forming effects, and produce metal iron can products that meet high standards.

[0016] The present invention has the function of accurately adjusting the position of the mold through the first position adjustment mechanism, the second position adjustment mechanism and the third position adjustment mechanism, and the can pressing mechanism can adjust the stamping parameters (such as hydraulic cylinder pressure adjustment, etc.) according to the requirements of different molds and iron cans. The equipment can easily cope with the processing requirements of metal iron cans of various sizes (large industrial iron cans, small cosmetic packaging cans, etc.) and different shapes (round, square, special-shaped, etc.), improve the versatility and applicability of the equipment, and can be widely used in the iron can packaging production field of different industries. It can not only be used for the complete processing flow from metal sheets to iron can finished products, but also be suitable for subsequent stamping, shaping and other processing operations on existing semi-finished products. The manipulator can accurately grab and place materials in different states, so that the equipment can be flexibly integrated into different production links to meet the diversified production process arrangements. The position adjustment mechanism adjusts the position by driving the screw rod with a motor, and the parameter setting is intuitive and simple. When replacing molds of different specifications or adjusting the type of processed products, the operator can easily debug the position, speed and other parameters of each mechanism through the control system, quickly complete the adjustment preparation work of the equipment, reduce the equipment debugging time and workload, and improve production efficiency.

[0017] The detection mechanism of the present invention utilizes an X-axis linear module and a Y-axis linear module to drive the detection camera to realize flexible mobile scanning in a two-dimensional plane, which can comprehensively detect the size and appearance quality of the iron can, timely and accurately screen out unqualified products, effectively control the quality in the production process, and ensure that the final finished products can meet high-precision quality requirements and meet the market demand for high-quality metal iron cans. The detection mechanism realizes precise movement of the two-dimensional plane through a linear module, and the detection camera has high resolution and advanced image recognition algorithms, which can accurately detect tiny defects on the surface of the iron can and slight deviations in size, providing a reliable basis for quality control, ensuring that only high-quality and high-precision iron cans can enter the finished product storage link, and effectively improving the overall quality level of the product.

[0018] The present invention basically realizes automated operation in the entire iron can processing process from mold position adjustment, loading, stamping, testing to unloading. The various mechanisms are coordinated and cooperated in an orderly manner through the control system, which reduces the manual intervention link and avoids the quality problems caused by human operation errors. In addition, the production operation can be carried out continuously and uninterruptedly, which greatly improves the production efficiency and meets the needs of large-scale production of metal iron cans. Since the position adjustment mechanism can accurately and quickly adjust the mold position, when it is necessary to replace molds of different specifications or types, compared with traditional fixed mold equipment, this equipment can complete the replacement and positioning of the upper and lower molds more quickly, shortening the mold change time, so that the equipment can be put into the production of the next batch of products more quickly, improving the effective utilization rate of the equipment, and further improving the overall production efficiency.

[0019] Each position adjustment mechanism of the present invention adopts a combination of screw drive and guide rail slider guidance, which can achieve millimeter-level position adjustment accuracy, ensure the precise spatial positioning of the upper mold and the lower mold, and the accurate scanning position of the detection camera during detection. From mold installation, stamping to quality inspection, each link guarantees high-precision spatial position requirements, and minimizes product quality problems caused by positioning errors. Various auxiliary structures (guide columns, springs, etc.) in the canning mechanism cooperate with the precise stamping power output of the hydraulic cylinder, so that the deformation control of metal materials during the stamping process is more accurate, the wall thickness of the can body is uniform, the shape is regular, and the dimensional tolerance can be controlled within a very small range. The produced iron cans can reach very high precision standards in terms of appearance and structural dimensions, which meets the market demand for high-precision iron can products, and is particularly suitable for industries with strict requirements on packaging accuracy, such as cosmetics, high-end food and other fields.

Example

[0027] See attached Figures 1 to 9A high-precision canning equipment for processing metal iron cans comprises a horizontally arranged workbench 1, a vertical plate 2 is vertically installed on the workbench 1, a first position adjustment mechanism 3 is arranged on the vertical plate 2, a second position adjustment mechanism 4 is arranged on the output end of the first position adjustment mechanism 3, a canning mechanism 5 is arranged on the output end of the second position adjustment mechanism 4, an upper mold 6 is arranged on the output end of the canning mechanism 5, the first position adjustment mechanism 3 drives the second position adjustment mechanism 4 to move along the X-axis direction, the second position adjustment mechanism 4 drives the canning mechanism 5 to move along the Z-axis direction, a third position adjustment mechanism 7 is arranged on the vertical plate 2, a lower mold 8 is arranged on the output end of the third position adjustment mechanism 7, and the third position adjustment mechanism 7 drives the lower mold 8 to move along the Y-axis direction.

[0028] A manipulator 10 is disposed on the workbench 1 , a semi-finished product storage box 11 and a finished product storage box 13 are disposed on one side of the workbench 1 , and a material discharge chute 12 is disposed above the finished product storage box 13 .

[0029] The first position adjustment mechanism 3, the second position adjustment mechanism 4 and the third position adjustment mechanism 7 have the same structure. The first position adjustment mechanism 3 includes two symmetrically arranged bearing seats 31, between which a screw rod 32 is rotatably mounted via a bearing, one end of the screw rod 32 is connected to a motor 33, a threaded barrel 34 is threadedly mounted on the screw rod 32, and the outer side of the threaded barrel 34 is fixedly connected to a moving block 36 via a connecting block 35. Guide rails 37 are symmetrically arranged on both sides of the screw rod 32, and a slider 38 is fixedly mounted on one end of the moving block 36 close to the screw rod 32, and the slider 38 is slidably mounted on the guide rail 37.

[0030] The tank pressing mechanism 5 includes a mounting plate 51 fixed on the output end of the second position adjustment mechanism 4, a hydraulic cylinder 52 and a mounting block 53 are fixedly mounted on the mounting plate 51, a piston rod of the hydraulic cylinder 52 extends out of the mounting block 53 and is fixedly connected to the upper mold 6, a plurality of guide columns 54 are fixedly mounted on the upper end of the upper mold 6, a linear bearing 56 is fixedly mounted on the mounting block 53, the guide column 54 is slidably mounted in the linear bearing 56, a limit block 55 is fixedly provided on the upper end of the guide column 54, a spring 57 is sleeved on the outer side of the guide column 54, the upper end of the spring 57 is fixedly connected to the linear bearing 56, and the lower end thereof is fixedly connected to the upper mold 6.

[0031] The detection mechanism 9 includes an X-axis linear module 91 fixed on the vertical plate 2, a Y-axis linear module 92 on the output end of the X-axis linear module 91, a camera mounting seat 93 fixedly installed on the output end of the Y-axis linear module 92, and a detection camera 94 fixedly installed on the camera mounting seat 93. The detection mechanism 9 is arranged above the lower mold 8.

[0032] Working principle: According to the specifications of the metal can to be processed, the third position adjustment mechanism 7 is activated by the control system to adjust the position of the lower die 8. The motor 33 rotates, driving the screw 32 to rotate. Since the threaded barrel 34 is threadedly matched with the screw 32, and the threaded barrel 34 is fixedly connected to the moving block 36 through the connecting block 35, and the slider 38 on the moving block 36 is slidably guided along the guide rail 37, the moving block 36 drives the lower die 8 to move to the preset accurate position along the Y-axis direction, so as to prepare for the subsequent stamping with the upper die 6.

[0033] Next, the first position adjustment mechanism 3 and the second position adjustment mechanism 4 work together to adjust the position of the upper die 6. The motor 33 of the first position adjustment mechanism 3 is started to move the second position adjustment mechanism 4 to a suitable lateral position along the X-axis direction; then the motor 33 of the second position adjustment mechanism 4 is operated to drive the can pressing mechanism 5 and the upper die 6 to move along the Z-axis direction, so that they are lowered to a height close to the initial height of the lower die 8, ensuring that the upper and lower dies are in roughly corresponding positions before stamping, and this position adjustment process can be precisely controlled to meet the positioning requirements of iron cans of different sizes and shapes.

[0034] The robot 10 grabs the metal sheet to be processed or the partially processed iron can semi-finished product from an external loading device (such as a silo, a conveyor belt, etc., not shown in the figure) and places it accurately on the lower mold 8.

[0035] The can pressing mechanism 5 starts to work, and the piston rod of the hydraulic cylinder 52 extends to push the upper mold 6 downward toward the lower mold 8. In this process, the guide column 54 fixed at the upper end of the upper mold 6 slides downward along the linear bearing 56 on the mounting block 53, playing a precise guiding role to ensure that the upper mold 6 and the lower mold 8 can be accurately matched. At the same time, the spring 57 sleeved on the outside of the guide column 54 is compressed, and the spring 57 plays a buffering role to prevent the upper mold 6 and the lower mold 8 from being damaged by excessive impact force at the moment of closing the mold, and can adapt to a certain small position deviation between the molds during the stamping process to ensure that the stamping action is stable and uniform. After the upper mold 6 and the lower mold 8 are closed, the metal sheet or semi-finished product is stamped to deform it according to the shape and size requirements of the mold, and the corresponding can body or iron can stamping process such as blanking, stretching, forming, etc. is completed to process it into a shape that meets the requirements.

[0036] After the stamping is completed, the upper die 6 returns to the initial height position driven by the retraction of the piston rod of the hydraulic cylinder 52, and the detection mechanism 9 starts to work at this time. The X-axis linear module 91 drives the Y-axis linear module 92 and the detection camera 94 thereon to move along the X-axis direction. After moving to the position above the iron can to be detected, the Y-axis linear module 92 drives the detection camera 94 to move along the Y-axis direction. Through this two-dimensional mobile scanning method, the detection camera 94 can comprehensively capture the images of various parts of the iron can, and then transmit the image information to the image processing unit in the control system. The image processing unit uses the preset image recognition algorithm and quality standard parameters to analyze and judge the dimensional accuracy (such as the diameter and height of the can body) and appearance quality (such as whether there are scratches, pits, wrinkles and other defects on the surface) of the iron can to determine whether the iron can meets the processing quality requirements.

[0037] If the test result shows that the iron can is a qualified product, the manipulator 10 grabs the iron can and moves it to the top of the finished product storage box 13 according to the instruction of the control system, and puts the iron can smoothly into the finished product storage box 13 for storage through the unloading chute 12; if the test result determines that the iron can is an unqualified semi-finished product, the manipulator 10 grabs it and places it into the semi-finished product storage box 11, and it can be reworked or otherwise processed later. This cycle is repeated, and the next round of metal sheet loading, stamping, testing, and unloading processes are continuously carried out to achieve batch processing and production of high-precision metal iron cans.

[0038] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
