Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology for coating equipment, and specifically relates to a material feeding device for coating equipment. Background Technology

[0002] In the automated production process of coating equipment, the feeding device is a key link in material transfer, and its operational stability and accuracy directly affect product quality and production efficiency. As industrial manufacturing demands increasing material diversity, the material forms in coating processing are becoming more complex. Among them, stepped materials, due to their special structural characteristics, are increasingly widely used in precision manufacturing fields such as electronics and optics.

[0003] Traditional feeding mechanisms generally use vacuum suction cups as the material gripping actuators. Their working principle involves a vacuum pump drawing air from the contact surface between the suction cup and the material, creating negative pressure to adsorb and fix the material. However, this traditional structure exhibits significant limitations when dealing with stepped materials: due to the distinct height differences in stepped materials, planar vacuum suction cups cannot form a complete seal with the material surface, resulting in discontinuous negative pressure zones. This easily leads to weak adhesion or even material detachment, severely affecting the stability of the feeding process.

[0004] Meanwhile, traditional vacuum suction cups are typically made of a single rubber material. Although rubber has a certain degree of elastic deformation, its cushioning performance is still insufficient in practical applications. When the suction cup comes into contact with materials, especially for coating materials with extremely high surface precision requirements, the instantaneous impact force between the suction cup and the material is difficult to effectively buffer, easily causing damage such as indentations and scratches on the material surface. This problem not only leads to a decrease in product yield and an increase in production costs, but also adversely affects subsequent coating processes, reducing the performance indicators of the final product.

[0005] To address this technical problem, a feeding device for coating equipment is provided. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a feeding device for coating equipment, which solves the problems of poor adaptability leading to unstable adsorption and insufficient buffering causing material damage when the feeding device of the coating equipment uses a vacuum suction cup to process stepped materials, as well as the low versatility requiring frequent suction cup replacement.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding device for a coating equipment includes a perforated hanger. A servo motor is fixedly installed inside the perforated hanger. The servo motor is a forward and reverse rotating motor. The output end of the servo motor extends to the bottom of the perforated hanger, and a telescopic rod is fixedly installed at the output end of the servo motor. Pneumatic telescopic rods for driving the telescopic rod to extend and retract are installed on both sides of the telescopic rod. A carrier plate is fixedly installed at the bottom end of the telescopic rod. Vacuum boxes are fixedly installed at both ends of the carrier plate. Multiple air holes are arranged through the lower surface of the vacuum boxes in a rectangular equidistant array. A suction cup is sealed inside each air hole. The suction cup is made of corrugated rubber, and the lower surface of the suction cup is provided with corrugated grooves. An external pipe is fixedly installed on the upper surface of the vacuum box, and the external pipe is connected to an external vacuum system.

[0009] In the above technical solution, springs are fixedly installed between the suction cup and the lower surface of the vacuum box.

[0010] In the above technical solution, the telescopic rod includes an inner rod, the top end of which is fixedly connected to the output end of the servo motor, a hollow outer rod is fitted on the outer surface of the inner rod, the bottom end of the outer rod is fixedly connected to the carrier plate, a keyway is provided on the outer surface of the inner rod, and a sliding key is provided on the inner side wall of the outer rod, with the sliding key and the keyway being slidably connected.

[0011] In the above technical solution, a fixing plate A is fixedly installed on the outer surface of the inner rod, a fixing plate B is fixedly installed on the outer surface of the outer rod, and the pneumatic telescopic rod is fixedly installed between the fixing plate A and the fixing plate B.

[0012] In the above technical solution, the outer surface of the outer rod is provided with nylon cable ties, and the outer end of the outer tube is penetrated by the nylon cable ties.

[0013] The present invention provides a feeding device for coating equipment, which, compared with the prior art, has the following advantages:

[0014] This utility model addresses the challenge of sealing and bonding stepped materials by placing a spring between the suction cup and the vacuum box, combined with a suction cup made of corrugated rubber and with corrugated grooves on its surface. This allows for independent elastic adjustment and deformation compensation of different stepped surfaces, forming a complete seal and preventing weak adsorption or material detachment, thus improving the adaptability to stepped materials.

[0015] In addition, to address the issue of surface damage to the coating, the rectangular array of suction cups disperses the adsorption force through large-area contact, and the springs convert rigid impacts into slow deformation forces. Combined with the flexible properties of the corrugated rubber, this avoids excessive local pressure that could damage the coating layer and improve product yield. Attached Figure Description

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-7 This utility model provides a technical solution:

[0026] A feeding device for a coating equipment includes a perforated hanger 1. A servo motor 2 is fixedly installed inside the perforated hanger 1. The servo motor 2 is a forward and reverse reversible motor. The output end of the servo motor 2 extends to the bottom of the perforated hanger 1, and a telescopic rod 3 is fixedly installed at the output end of the servo motor 2. Pneumatic telescopic rods 4 for driving the telescopic rod 3 to extend and retract are installed on both sides of the telescopic rod 3. The pneumatic telescopic rods 4 are connected to an external power source through air pipes. A carrier plate 5 is fixedly installed at the bottom end of the telescopic rod 3. Vacuum boxes 6 are fixedly installed at both ends of the carrier plate 5. Multiple air holes are arranged through the lower surface of the vacuum box 6. The multiple air holes are arranged in a rectangular equidistant array, and a suction cup 61 is sealed and installed in each air hole. The suction cup 61 is made of corrugated rubber, and a corrugated groove 611 is provided on the lower surface of the suction cup 61. An external pipe 62 is fixedly installed on the upper surface of the vacuum box 6. The external pipe 62 is connected to an external vacuum system. A spring 63 is fixedly installed between the suction cup 61 and the lower surface of the vacuum box 6.

[0027] Specifically, combined Figure 1 , Figure 2 and Figure 3 As shown, mounting grooves 51 are provided through both the left and right ends of the upper surface of the carrier plate 5. The vacuum box 6 is fixedly installed in the corresponding mounting grooves 51 by bolts to achieve a fixed connection with the carrier plate 5.

[0028] In use, after the perforated hanger 1 is securely installed at the material handling and unloading points of the equipment, the pneumatic telescopic rod 4 drives the telescopic rod 3 to extend precisely, allowing the carrier plate 5 to bring the vacuum box 6 and suction cups 61 into stable contact with the material. The multiple suction cups 61, arranged in a rectangular array, can disperse the adsorption force through large-area uniform contact, avoiding concentrated force at a single point. Meanwhile, the spring 63 between the suction cups 61 and the vacuum box 6 achieves "soft contact" through elastic deformation at the moment of contact, effectively buffering the instantaneous impact caused by mechanical alignment errors or excessively fast descent speed, and converting the pressure into a slow, gentle force. Deformation force prevents the coating layer from being marked or damaged due to excessive local pressure; at the same time, the corrugated rubber suction cup 61 itself has good flexibility and sealing performance, and the corrugated grooves 611 on its surface can further enhance the adhesion to the material surface. Even if there are slight unevenness in the material, the adaptive adjustment of the spring 63 can make each suction cup 61 fit tightly against the workpiece surface. With the help of the external vacuum system, after the vacuum box 6 is evacuated through the external pipe 62, a stable and uniform adsorption force can be formed to ensure that the material does not fall off or deform during the transfer process.

[0029] Furthermore, when adsorbing stepped materials, due to the height difference on the surface of the stepped materials, the spring 63 between the suction cup 61 and the vacuum box 6 can independently adjust the elastic extension and contraction according to the height difference of different stepped surfaces. The suction cup 61 at the higher step is compressed, and the suction cup 61 at the lower step is tightly attached under the push of the spring 63, ensuring that the suction cup 61 on each stepped surface can be evenly stressed and form an effective seal. At the same time, the corrugated rubber suction cup 61 itself has deformable characteristics, and the corrugated grooves 611 on its surface can further compensate for the small gaps at the step transition. After the vacuum box 6 is evacuated by the external vacuum system through the external pipe 62, a stable and consistent adsorption force can be formed on different stepped surfaces, avoiding local incomplete adsorption or pressure concentration due to the step height difference. This prevents the material from tilting, falling off, or being damaged in the coating layer of the stepped surface due to uneven force during the transfer process, significantly improving the adaptability and adsorption safety of irregularly shaped stepped coated materials.

[0030] It should be noted that the vacuum boxes 6 on the left and right sides, together with the suction cups 61 on the same side, are used to adsorb the material to be coated and the material after coating, respectively. After the material to be coated and the material to be coated are adsorbed and fixed by the suction cups 61 on the left and right sides, the material is moved up a certain distance by the retraction of the pneumatic telescopic rod 4. Then, the servo motor 2 rotates 180° to exchange the positions of the suction cups 61 on the left and right sides. After that, the telescopic rod 4 is extended to move the material down to each area. After the external vacuum system releases the pressure of the vacuum box 6 through the external pipe 62, the workpiece falls freely to the corresponding position, thus completing the loading and unloading of the coating material.

[0031] The overall structure balances adsorption stability, workpiece protection, and equipment flexibility, significantly improving the safety and reliability of the loading and unloading process for coated materials.

[0032] Combination Figure 1 , Figure 6 and Figure 7 As shown, the telescopic rod 3 includes an inner rod 31, the top end of which is fixedly connected to the output end of the servo motor 2, a hollow outer rod 32 is sleeved on the outer surface of the inner rod 31, the bottom end of the outer rod 32 is fixedly connected to the carrier plate 5, a keyway 312 is provided on the outer surface of the inner rod 31, and a sliding key 322 is provided on the inner side wall of the outer rod 32, and the sliding key 322 is slidably connected to the keyway 312.

[0033] By sliding the keyway 312 on the outer surface of the inner rod 31 and the sliding key 322 on the inner side wall of the outer rod 32, precise guidance without relative rotation between the two is achieved, ensuring that when the servo motor 2 rotates, it can precisely drive the carrier plate 5 to rotate through the telescopic rod 3, thereby stably completing the work of swapping the vacuum boxes 6 on the left and right sides.

[0034] Combination Figure 1 , Figure 6 and Figure 7 As shown, a fixing plate A311 is fixedly installed on the outer surface of the inner rod 31, and a fixing plate B321 is fixedly installed on the outer surface of the outer rod 32. The pneumatic telescopic rod 4 is fixedly installed between the fixing plate A311 and the fixing plate B321. The two ends of the pneumatic telescopic rod 4 are respectively connected to the inner rod 31 and the outer rod 32 to ensure that the pneumatic telescopic rod 4 can stably output thrust or pull force during the extension and retraction process, drive the inner rod 31 and the outer rod 32 to slide relative to each other, thereby realizing the smooth lifting and lowering of the carrier plate 5 and the vacuum box 6 and suction cup 61 below, avoiding the lifting and shaking caused by the unstable installation of the pneumatic telescopic rod 4, and further ensuring the stability and accuracy of the suction cup 61 when in contact with the material.

[0035] In the above technical solution, the outer surface of the outer rod 32 is provided with nylon cable ties, and the outer end of the outer pipe 62 passes through the nylon cable ties. The nylon cable ties can fix the outer pipe 62 neatly and orderly to the surface of the outer rod 32, preventing the outer pipe 62 from shaking randomly or getting tangled or rubbing against other components during the operation of the device due to the extension and retraction of the telescopic rod 3 and the rotation of the carrier plate 5. This prevents the outer pipe 62 from leaking due to pulling and wear, ensuring the stable operation of the vacuum system. At the same time, it also makes the pipeline layout of the overall device neater and facilitates later maintenance and repair.
