Description

Technical Field

[0001] This utility model relates to the field of mechatronics technology, and in particular to a plaster delivery device with an arc-shaped guide rail. Background Technology

[0002] In the field of plaster production, automated conveying systems are a core component connecting processes such as molding, gluing, cooling, and packaging, and their performance directly affects production efficiency and product quality. With the diversification of plaster types, such as round, irregular shapes, different thicknesses, and the increasing automation of production lines, higher demands are placed on the stability, accuracy, and compatibility of conveying devices. In particular, complex conveying path scenarios involving curved turns have become a key direction for technological optimization.

[0003] Existing plaster conveying devices mostly consist of linear guides, spliced ​​arc-shaped guides, trays, and drive mechanisms. Their working principle involves a motor driving a conveyor belt, which in turn moves the tray carrying the plasters along the guides. However, in practical applications, these devices suffer from significant technical bottlenecks: insufficient stability of the arc-shaped section during conveying; traditional arc-shaped guides are often composed of spliced ​​linear and arc-shaped sections, with slight step differences at the joints, causing jerky vibrations when the tray passes through, easily leading to edge displacement or surface wrinkling of the plasters; simultaneously, when the arc-shaped section turns, the tray is subjected to centrifugal force and shifts outwards, which is not addressed by existing fixed guiding structures. The adaptive method for offsetting lateral forces often results in problems such as friction between the tray and the guide rail, and adhesion and wear of the plaster, especially during high-speed conveying, where the product loss rate can reach 8%-10%. On the other hand, the linkage between plaster positioning and quality inspection is poor. The trays of existing devices mostly use simple placement or single adsorption methods to fix the plaster, which is difficult to adapt to the stable load-bearing requirements of plasters of different thicknesses. Moreover, there is a lack of integrated online detection and sorting functions. When the plaster has defects such as air bubbles or irregular edges, manual sorting is required during the conveying process, which is not only inefficient but also prone to secondary contamination of qualified plasters due to manual operation.

[0004] In addition, the existing equipment has significant compatibility limitations. When changing to different specifications of plasters, it is necessary to manually adjust the guide rail spacing, tray size and guide structure, with a switching cycle of up to 30-60 minutes, which is difficult to meet the flexible production needs of small batches and multiple varieties. Therefore, in response to the core pain points such as the stability of the arc section, adaptive load-bearing capacity and intelligent detection linkage, the development of an efficient and stable plaster conveying device with arc-shaped guide rails has become the key to promoting the upgrading of the plaster automated production line.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a plaster conveying device with an arc-shaped guide rail, including a base 1, a bracket 2 fixedly connected to the base 1, a straight guide rail 4 fixedly connected to the bracket 2, an arc-shaped guide rail 5 fixedly connected to the straight guide rail 4, a coil device 6 fixedly connected to both the straight guide rail 4 and the arc-shaped guide rail 5, a conveyor belt 7 provided on both the straight guide rail 4 and the arc-shaped guide rail 5, and guide wheels 8 fixedly connected to both sides of the arc-shaped guide rail 5;

[0031] A tray 9 is provided on the conveyor belt 7. A notch 16 is opened on one side of the tray 9. A permanent magnet 12 is fixedly connected to the bottom of the tray 9. A vacuum suction cup 10 is fixedly connected inside the tray 9. A negative pressure sensor 11 is fixedly connected to the top of the tray 9.

[0032] The guide wheels 8 on both sides of the arc-shaped guide rail 5 form a lateral limit on the tray 9. Together with the stable support of magnetic levitation, they counteract the influence of centrifugal force on the tray 9, ensuring that the plaster does not shift laterally when turning in the arc section, and ensuring the accuracy of the delivery trajectory.

[0033] The permanent magnet 12 below the tray 9 forms a magnetic levitation structure with the coil device 6 below the straight guide rail 4 and the arc-shaped guide rail 5. When the coil device 6 is energized, it generates an electromagnetic field, which interacts with the magnetic force of the permanent magnet 12, causing the tray 9 to levitate on the surface of the guide rail, greatly reducing mechanical friction.

[0034] A support column 3 is fixedly connected to the base 1, a mounting column 13 is fixedly connected to the support column 3, a vision sensor 14 is fixedly connected to the mounting column 13, and a lidar 15 is fixedly connected to the mounting column 13.

[0035] A notch 16 is provided on the outer side of the straight guide rail 4. A support column 3 is fixedly connected to the base 1. A mounting column 13 is fixedly connected to the support column 3. A telescopic rod 17 is provided on the mounting column 13. A push plate 18 is fixedly connected to the telescopic rod 17. A motor 19 is fixedly connected to one side of the mounting column 13.

[0036] Working principle: After the device is started, the bracket 2 on the base 1 supports the straight guide rail 4 and the arc guide rail 5 to maintain stability. When the plaster is placed on the tray 9 of the conveyor belt 7, the permanent magnet 12 under the tray 9 forms a magnetic levitation structure with the coil device 6 under the straight guide rail 4 and the arc guide rail 5. The coil device 6 generates an electromagnetic field when energized, which interacts with the magnetic force of the permanent magnet 12, making the tray 9 levitate on the surface of the guide rail, greatly reducing mechanical friction. At the same time, the vacuum suction cup 10 in the tray 9 is activated, and the back of the plaster is adsorbed by negative pressure. The negative pressure sensor 11 on the tray 9 monitors the adsorption force in real time and feeds the data back to the control system to ensure that plasters of different thicknesses can be firmly fixed and avoid falling off during transportation.

[0037] When the conveyor belt 7 carries the pallet 9 along the straight guide rail 4 into the arc guide rail 5, the guide wheels 8 on both sides of the arc guide rail 5 form a lateral limit on the pallet 9. Combined with the stable support of magnetic levitation, it offsets the influence of centrifugal force on the pallet 9, ensuring that the plaster does not shift laterally when turning in the arc section, and ensuring the accuracy of the conveying trajectory.

[0038] When the tray 9 moves to the position of the vision sensor 14 and the lidar 15, the vision sensor 14 identifies whether there are defects such as bubbles and wrinkles on the surface of the plaster, and the lidar 15 simultaneously measures the real-time coordinates of the tray 9. After the data of the two are fused, it is determined whether the plaster is qualified. If it is unqualified, the control system records the position information of the corresponding tray 9.

[0039] When the unqualified pallet 9 runs to the notch 16 outside the straight guide rail 4, the motor 19 of the column 13 mounted on the support column 3 drives the telescopic rod 17 to extend, which drives the push plate 18 to pass through the notch 16 and push the unqualified plaster on the pallet 9 into the waste channel; after sorting is completed, the telescopic rod 17 is reset, which does not affect the normal conveying of subsequent pallets 9.

[0040] Throughout the process, magnetic levitation reduces friction to ensure high-speed transport, vacuum adsorption and guide wheels 8 ensure the stability of the arc section, and vision sensor 14 and lidar 15 enable quality detection and positioning linkage, ultimately achieving continuous, stable and precise transport of plaster from the straight section to the arc section, while automatically sorting out defective products, adapting to the high-efficiency operation requirements of automated production lines.

[0041] Structural Description:

[0042] The base 1 is used to fix the support bracket 2 and all components of the entire device. By increasing the contact area with the ground, the center of gravity of the device is lowered, the overall vibration of the conveyor belt 7 during operation is reduced, and a stable installation foundation is provided for each guide rail and functional module, ensuring the rigidity and stability of the structure during the conveying process.

[0043] The bracket 2 is fixedly connected above the base 1 to support the straight guide rail 4 and the arc guide rail 5. Its height can be adjusted according to the production line layout. The horizontality of the guide rail installation is ensured by welding or bolt connection to avoid the tray 9 from running off-center due to the tilt of the guide rail, and to provide a straight and stable path support for the delivery of plaster.

[0044] The straight guide rail 4 is fixed on the bracket 2 and is fixedly connected with the arc-shaped guide rail 5 to form a continuous conveying path. The straight guide rail 4 provides a channel for the straight section of plaster conveying, while the arc-shaped guide rail 5 realizes the turning conveying of plaster. The integrated connection design of the two eliminates the joints and abruptness of the traditional splicing structure, ensuring that the tray 9 is smooth and impact-free when transitioning between the straight and arc sections, and reducing the wrinkles or displacement of plaster caused by vibration.

[0045] The coil device 6 is fixed below the straight guide rail 4 and the arc guide rail 5, and is set opposite to the permanent magnet 12 under the tray 9. When energized, it generates an electromagnetic field and forms a magnetic levitation force with the permanent magnet 12, which greatly reduces the mechanical friction between the tray 9 and the guide rail, thereby improving the conveying speed and reducing the edge wear of the plaster caused by friction.

[0046] The conveyor belt 7 is set on the straight guide rail 4 and the arc guide rail 5 to drive the pallet 9 to move along the guide rail. It is made of food-grade polyurethane material, with a smooth surface and a certain degree of elasticity, which can be adapted to the magnetic levitation movement of the pallet 9, avoiding the rigid friction of traditional conveyor belts, and reducing the vibration transmission during the plaster conveying process.

[0047] The guide wheels 8 are fixed on both sides of the arc-shaped guide rail 5 and are evenly distributed along the arc-shaped trajectory. The wheel surface is made of polyurethane elastic material and maintains a gap of 0.3-0.8mm with the side of the tray 9. When the tray 9 is subjected to centrifugal force in the arc section, the guide wheels 8 provide lateral restraint through rolling contact, which not only counteracts the centrifugal force to prevent lateral displacement, but also avoids tray wear caused by sliding friction, ensuring accurate positioning of the plaster when turning.

[0048] The tray 9 is set on the conveyor belt 7 to carry the plaster. Its surface is flat and the edges are rounded to avoid scratching the plaster. The notch 16 on one side of the tray 9 provides operating space for the push plate 18 when sorting unqualified products, ensuring that the sorting action does not interfere with the normal operation of the tray.

[0049] Vacuum suction cups 10 are fixed inside tray 9 and arranged in an array. They adsorb the back of the plaster through negative pressure. The negative pressure sensor 11 on tray 9 monitors the adsorption force in real time. The negative pressure can be automatically adjusted according to the thickness of the plaster. Low negative pressure is used for thin plasters to prevent damage, and high negative pressure is used for thick plasters to prevent them from falling off. This meets the stable bearing requirements of plasters of various specifications.

[0050] The permanent magnet 12 is fixed below the tray 9 and works with the coil device 6 under the guide rail to form a magnetic levitation structure, which reduces the direct contact between the tray 9 and the guide rail, reduces running resistance, and avoids the vibration of the tray 9 caused by traditional mechanical contact, thus providing a stable bearing environment for the plaster.

[0051] Mounting column 13 is fixed on support column 3 and is used to install detection and execution components such as vision sensor 14, lidar 15 and telescopic rod 17. Its height is adjustable to ensure that the sensor lens and the upper surface of tray 9 maintain the best detection distance and improve detection accuracy.

[0052] The vision sensor 14 is fixed on the mounting post 13, and the lens is vertically aligned with the plaster on the tray 9. It identifies defects such as bubbles and wrinkles on the surface of the plaster through high-definition imaging, providing visual data for quality judgment, replacing manual visual inspection, and improving the efficiency and accuracy of defect identification.

[0053] The lidar 15 is fixed on the mounting column 13 and works in conjunction with the vision sensor 14. It acquires the three-dimensional coordinates of the tray 9 in real time through laser scanning, and combines the defect information of the vision sensor 14 to accurately locate the position of the defective product, ensuring the accuracy of the sorting action.

[0054] The notch 16 on the outside of the straight guide rail 4 is the entrance to the non-conforming product sorting channel. Its width is slightly larger than the diameter of the plaster. When the push plate 18 pushes the non-conforming plaster out of the tray 9, the notch 16 provides a falling channel for the plaster, so as to avoid non-conforming products from being stuck on the guide rail and affecting subsequent conveying.

[0055] The telescopic rod 17 is mounted on the mounting column 13. One end is connected to the push plate 18, and the other end is driven by the motor 19, which can extend and retract quickly. When a defective product is detected, the telescopic rod 17 drives the push plate 18 through the notch 16 to push the plaster into the waste channel, thereby realizing the automated sorting of defective products and reducing manual intervention.

[0056] The push plate 18 is fixed to the end of the telescopic rod 17. A silicone buffer layer is pasted on the side that contacts the plaster. When pushing defective products, it can buffer the impact force and avoid the plaster from breaking or the tray 9 from vibrating due to rigid contact. At the same time, the anti-slip property of the silicone material ensures that the plaster does not slip during the pushing process.

[0057] The motor 19 is fixed to one side of the mounting column 13 to provide power to the telescopic rod 17. It adopts a servo motor and can precisely control the extension stroke and speed of the telescopic rod 17 through the control system to ensure that the sorting action is synchronized with the running rhythm of the pallet 9 and avoids interfering with the normal conveying process.

[0058] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
