Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically a coating machine loading and unloading device. Background Technology

[0002] With the continuous development of coating technology, various coating equipment and their loading and unloading devices have been widely used in industrial production. However, these devices still have some problems in practical applications, especially in terms of efficiency, automation level, and adaptability to complex processes during loading and unloading. For example, although some existing coating machine loading and unloading devices have achieved partial automation, they still have shortcomings in continuous operation capability, space utilization, and precise control, resulting in limited production efficiency or complex operation.

[0003] A search revealed a "coating machine loading and unloading device" with publication number CN112278861B, published on September 13, 2024. This design includes a loading conveyor line, an unloading conveyor line, a gripping device, and a buffer device. The buffer device enables continuous handling of products during the coating process. While this structure improves work efficiency to some extent, its gripping device design is relatively simple, only suitable for products of specific sizes or shapes, making it difficult to meet the loading and unloading needs of diverse products. Furthermore, the layout of the buffer device limits the space utilization of the equipment and may cause congestion during mass production, affecting the overall operational smoothness.

[0004] A search revealed a "coating equipment and coating method" with publication number CN117660915B, published on June 14, 2024. This design achieves independent control of the vacuum environment during loading and unloading by installing a gate valve between the coating chamber and the loading / unloading chamber. This design effectively protects the process environment within the coating chamber; however, the reciprocating motion mechanism of its loading / unloading shafts is relatively complex, increasing the manufacturing cost and maintenance difficulty of the equipment. Furthermore, due to the limited range of motion of the loading / unloading shafts, compatibility issues may arise when dealing with larger workpieces, and its automation level relies on an external drive mechanism, making it difficult to completely eliminate the need for manual intervention.

[0005] The aforementioned problems indicate that current coating machine loading and unloading equipment still has room for improvement in terms of flexibility, space utilization efficiency, and automation level. Therefore, this invention provides a novel coating machine loading and unloading device to overcome the shortcomings of existing technologies and achieve a more efficient, flexible, and adaptable loading and unloading solution.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] This utility model provides a loading and unloading device for a coating machine, the specific implementation of which is described in conjunction with the attached drawing. Figure 1 To be continued Figure 3 A detailed description is provided. The equipment includes a base 1, a conveying mechanism 2, a clamping and positioning mechanism 3, and a drive module 4. These parts are mechanically connected and power transmitted to achieve automated loading and unloading of workpieces.

[0020] The base 1 serves as the fundamental support structure for the entire equipment. A conveying mechanism 2 is mounted on its top, and a clamping and positioning mechanism 3 is installed on one side of the conveying mechanism 2. The clamping and positioning mechanism 3 is fixedly connected to the base 1 via a bracket. The drive module 4 is installed at the bottom of the base 1 and works in conjunction with the conveying mechanism 2 and the clamping and positioning mechanism 3. Slide rails 6 are symmetrically fixed to both sides of the base 1, and a transmission chain 5 is installed between the slide rails 6. Drive gears 8 and driven gears 9 are respectively meshed at both ends of the transmission chain 5. The central shaft of the drive gear 8 passes through the base 1 and connects to the output end of the drive module 4. Multiple carrying trays 7 are evenly distributed on the outer wall of the transmission chain 5. A groove is formed at the bottom of each carrying tray 7, and the groove is slidably connected to the slide rails 6. A feeding channel is provided on one side of the base 1, and a discharging channel is provided on the other side, with the discharging channel located above the feeding channel. This arrangement allows workpieces to enter through the feeding channel and be transferred to the discharging channel via the conveying mechanism 2 to complete the loading and unloading operations.

[0021] The specific operating principle of the conveying mechanism 2 is as follows: The main motor 18 in the drive module 4 drives the eccentric wheel 20 to rotate via the transmission belt 19. The eccentric wheel 20 transmits power to the drive gear 8 of the transmission chain 5 through the connecting rod group 21, thereby driving the transmission chain 5 to move along the slide rail 6. The movement of the transmission chain 5 causes the carrying tray 7 to slide smoothly along the slide rail 6. The top of the carrying tray 7 is provided with a positioning groove, the shape of which matches the bottom contour of the workpiece to be coated, ensuring that the workpiece remains stable during transportation. The design of the slide rail 6 effectively reduces the vibration of the transmission chain 5 during operation, avoiding the workpiece displacement problem caused by mechanical vibration in traditional equipment.

[0022] The clamping and positioning mechanism 3 includes a rotating arm 10, a gripper assembly 11, an adjusting screw 12, and a guide sleeve 13. The rotating arm 10 is rotatably connected to the top of the bracket. The gripper assembly 11 is mounted on one end of the rotating arm 10, and the other end is connected to the output end of the drive module 4 via a connecting rod. The gripper assembly 11 includes a fixed clamping plate 14, a movable clamping plate 15, an elastic element 16, and a guide post 17. The fixed clamping plate 14 is fixed to one end of the rotating arm 10. The movable clamping plate 15 is symmetrically arranged on one side of the fixed clamping plate 14. A guide hole is opened at one end of the movable clamping plate 15, and the guide post 17 is slidably connected within the guide hole. One end of the guide post 17 is fixed to the outer wall of the fixed clamping plate 14, and a limiting block is provided at the other end. The elastic element 16 is sleeved on the outer wall of the guide post 17. One end of the elastic element 16 abuts against the outer wall of the fixed clamping plate 14, and the other end abuts against the outer wall of the movable clamping plate 15. An adjusting screw 12 is provided in the middle of the rotating arm 10. One end of the adjusting screw 12 passes through the rotating arm 10 and is connected to the guide sleeve 13. The guide sleeve 13 is fixed to the top of the bracket. A handwheel is provided at the other end of the adjusting screw 12. By rotating the handwheel to adjust the position of the adjusting screw 12, the angle of the rotating arm 10 can be changed, thereby adapting to the workpiece clamping requirements of different heights and positions.

[0023] The working process of the clamping and positioning mechanism 3 is as follows: When the drive module 4 drives the rotating arm 10 to rotate via the linkage group 21, the gripper assembly 11 moves with the rotating arm 10 to the position of the workpiece. The fixed clamping plate 14 and the movable clamping plate 15 achieve the clamping operation of the workpiece through the cooperation of the guide post 17 and the elastic element 16. The elastic element 16 adopts a helical spring design, and each elastic element 16 is installed corresponding to one guide post 17. The elastic element 16 provides a buffering effect during the clamping process to prevent excessive clamping force from damaging the surface of the workpiece. Anti-slip pads are provided on the inner walls of both the fixed clamping plate 14 and the movable clamping plate 15. The surface of the anti-slip pads is distributed with concave and convex textures, which further enhances the clamping stability. In addition, the cooperation between the adjusting screw 12 and the guide sleeve 13 enhances the overall stability of the clamping and positioning mechanism 3, ensuring that the workpiece will not shift during the clamping process.

[0024] The drive module 4 comprises a main motor 18, a transmission belt 19, an eccentric wheel 20, and a connecting rod assembly 21. The main motor 18 is fixed to the bottom of the base 1. The top of the output shaft of the main motor 18 is fixed to the transmission belt 19, and the other end of the transmission belt 19 is connected to the eccentric wheel 20. The connecting rod assembly 21 is hinged to the outer wall of the eccentric wheel 20. One end of the connecting rod assembly 21 is connected to the drive gear 8 of the transmission chain 5, and the other end is connected to the connecting rod of the rotating arm 10. The main motor 18 drives the eccentric wheel 20 to rotate via the transmission belt 19. The eccentric wheel 20 transmits power to the conveying mechanism 2 and the clamping and positioning mechanism 3 via the connecting rod assembly 21, achieving centralized power distribution and simplifying the equipment structure.

[0025] The entire operation process of the equipment is as follows: The workpiece enters the base 1 through the feeding channel. The transmission chain 5 in the conveying mechanism 2 moves smoothly along the slide rail 6 under the action of the drive module 4, transferring the workpiece from the feeding channel to the working area of ​​the clamping and positioning mechanism 3. The rotating arm 10 in the clamping and positioning mechanism 3 rotates to the workpiece position under the drive of the drive module 4. The gripper assembly 11 completes the clamping operation of the workpiece through the cooperation of the fixed clamping plate 14 and the movable clamping plate 15. Subsequently, the rotating arm 10 transfers the workpiece to the discharge channel, completing the loading and unloading operation. During this process, the cooperation of the adjusting screw 12 and the guide sleeve 13 ensures the stability of the clamping and positioning mechanism 3, while the design of the elastic element 16 and the anti-slip pad effectively protects the workpiece surface from damage.

[0026] The above embodiments describe in detail the connection relationships, positional relationships, and mutual cooperation relationships between the various components of this utility model, ensuring the stability and reliability of the equipment in practical applications. Through the coordinated work of the conveying mechanism 2 and the clamping and positioning mechanism 3, the equipment achieves continuous movement and precise clamping of the workpiece, significantly improving work efficiency and reducing the need for manual intervention. Meanwhile, the structural design of the drive module 4 simplifies the overall structure of the equipment, reduces maintenance costs, and is suitable for processing workpieces of various sizes and shapes. To better enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0027] First, the workpiece enters the support tray 7 of the base 1 through the feeding channel. At this time, the positioning groove of the support tray 7 matches the bottom contour of the workpiece, ensuring the workpiece remains stable during transportation. After the main motor 18 starts, it drives the eccentric wheel 20 to rotate through the transmission belt 19. The eccentric wheel 20 transmits power to the drive gear 8 of the transmission chain 5 through the connecting rod group 21, thereby driving the transmission chain 5 to move smoothly along the slide rail 6. The movement of the transmission chain 5 causes the support tray 7 to slide along the slide rail 6, transferring the workpiece from the feeding channel to the working area of ​​the clamping and positioning mechanism 3. In this process, the design of the slide rail 6 effectively reduces the vibration of the transmission chain 5 during operation, avoiding workpiece displacement problems caused by mechanical vibration, thereby ensuring the stability of the workpiece during transportation.

[0028] When the workpiece reaches the working area of ​​the clamping and positioning mechanism 3, the drive module 4 drives the rotating arm 10 to rotate via the linkage group 21, causing the gripper assembly 11 to move to the workpiece's position. The fixed clamping plate 14 and the movable clamping plate 15 complete the workpiece clamping operation through the cooperation of the guide post 17 and the elastic element 16. Specifically, the movable clamping plate 15 moves closer to the fixed clamping plate 14 under the guidance of the guide post 17, and the elastic element 16 provides a buffering effect during clamping to prevent excessive clamping force from damaging the workpiece surface. At the same time, the anti-slip pads on the inner walls of the fixed clamping plate 14 and the movable clamping plate 15 further enhance the clamping stability. The cooperation between the adjusting screw 12 and the guide sleeve 13 ensures that the angle of the rotating arm 10 is adjustable to adapt to the workpiece clamping requirements of different heights and positions, thereby improving the flexibility of the equipment.

[0029] After clamping, the rotating arm 10, driven by the drive module 4, transfers the workpiece to the discharge channel, completing the loading and unloading operation. During this process, the cooperation between the adjusting screw 12 and the guide sleeve 13 not only enhances the overall stability of the clamping and positioning mechanism 3 but also ensures that the workpiece does not shift during clamping and transfer. Furthermore, the design of the elastic element 16 effectively buffers the impact force during clamping, protecting the workpiece surface from damage and further improving the applicability and reliability of the equipment.

[0030] During the entire operation of the equipment, the main motor 18 drives the eccentric wheel 20 to rotate via the transmission belt 19. The eccentric wheel 20 distributes power to the conveying mechanism 2 and the clamping and positioning mechanism 3 through the connecting rod group 21, simplifying the equipment structure and reducing maintenance costs. The positioning groove design of the bearing pallet 7 and the vibration damping function of the slide rail 6 together ensure the stability of the workpiece during transportation, while the elastic element 16 and anti-slip pad design of the gripper assembly 11 further improve the safety and accuracy of the clamping operation.

[0031] As can be seen from the above steps, this utility model achieves continuous movement and precise clamping of workpieces through the coordinated operation of the conveying mechanism 2 and the clamping and positioning mechanism 3, significantly improving work efficiency and reducing the need for manual intervention. Meanwhile, the structural design of the drive module 4 simplifies the overall structure of the equipment, making it suitable for processing workpieces of various sizes and shapes, and solving the shortcomings of existing coating machine loading and unloading equipment in terms of flexibility, space utilization, and automation level.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
