Description

Technical Field

[0001] This utility model relates to the technical field of suspended conveying devices, specifically a suspended conveying device for painting automotive parts. Background Technology

[0002] During use, cars come into contact with various external environmental factors, such as rain, moisture, salt, and corrosive substances like acids and alkalis. Painting can form a protective film on the surface of car parts, preventing these substances from directly contacting the metal surface, thereby slowing down or preventing corrosion and extending the service life of car parts.

[0003] Existing technologies use suspended conveyor systems composed of guide rails, electrically controlled sliders, and brackets to continuously transport automotive parts to the painting equipment for painting. However, to ensure painting quality, the automotive parts must remain in a fixed position during the painting process. This requirement greatly limits the flexibility of the painting operation, making it difficult for the parts facing away from the painting equipment to receive sufficient paint coverage when the automotive parts are transported to a fixed position for painting. This results in ineffective painting operations and problems such as uneven paint surface and missed areas. To address the shortcomings of existing technologies, we propose a suspended conveyor system for automotive parts painting to solve the above problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides a suspension conveyor device for painting automotive parts, which solves the problem that when automotive parts are conveyed to a fixed position for painting, the parts facing away from the painting equipment are difficult to be adequately covered with paint, resulting in ineffective painting operations, uneven paint surface, and missed spraying, and achieves steering adjustment under the premise of fixed positioning of automotive parts.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] This utility model discloses a suspension conveying device for painting automotive parts.

[0030] According to the appendix Figure 1-7 As shown, the system includes a guide rail 1, multiple sets of electrically controlled sliders 2 slidably mounted on the outer wall of the guide rail 1, and a bracket 3 located at the lower part of the electrically controlled sliders 2. Automotive parts, such as pipes, are suspended on the bracket 3. An electric telescopic rod 6 for adjusting the vertical position of the bracket 3 is fixedly connected to the bottom surface of the electrically controlled sliders 2. Specifically, when applying protective paint to the automotive parts, the automotive parts are first suspended on the bracket 3. Then, the switch inside the electrically controlled slider 2 is turned on, causing the electrically controlled slider 2 to automatically slide along the guide rail 1 to the painting equipment. Depending on the height setting of the painting equipment, the electric telescopic rod 6 is activated, causing the electric telescopic rod 6 to move the bracket 3 upwards or downwards, thereby positioning the automotive parts on the bracket 3 in the corresponding position with the painting equipment. The painting equipment then sprays protective paint onto the outer surface of the automotive parts. The painting equipment is not specifically shown in the attached diagram.

[0031] See attached document Figure 2-6 The inner surface of the bracket 3 is provided with a positioning mechanism 4. This positioning mechanism 4 allows multiple sets of different types of automotive parts to be securely placed on the bracket 3, while simultaneously driving the automotive parts to rotate circumferentially, ensuring uniform and complete painting of the outer surface of the automotive parts. The positioning mechanism 4 includes positioning cylinders 41, with multiple sets of positioning cylinders 41 rotatably mounted on the inner surface of the bracket 3. Positioning plates 42 for supporting and positioning the automotive parts are hinged to the outer walls of the multiple sets of positioning cylinders 41. An adjusting screw 43 is rotatably mounted inside the positioning cylinder 41, and a bolt is threaded to the outer wall of one end of the adjusting screw 43 extending to the outside of the positioning cylinder 41. A combined threaded seat 44 and a control plate 45 are provided between the screw 43 and the positioning plate 42 for adjusting the opening angle of the positioning plate 42. The threaded seat 44 is threadedly sleeved on the outer wall of the adjusting screw 43. One end of the control plate 45 is rotatably connected to the outer wall of the threaded seat 44. A connecting block 46 is hinged to the end of the control plate 45 away from the threaded seat 44. The connecting block 46 is slidably connected to the positioning plate 42. A groove 47 for limiting the sliding of the connecting block 46 is provided on one side of the positioning plate 42. An anti-sliding block 5 is fixedly connected to one end of the positioning plate 42. The anti-sliding block 5 can increase the connection stability between the inner wall of the automotive parts and the positioning plate 42.

[0032] See attached document Figure 6-7 The steering assembly 48 is disposed on the bottom surface of the bracket 3. The steering assembly 48 includes a connecting rod 482 that is fixedly connected to the bottom end of multiple sets of positioning cylinders 41, a first gear 483 fixedly disposed on the outer wall of the connecting rod 482, and a second gear 484 that meshes with multiple sets of first gears 483 simultaneously. A drive motor 485 is disposed at one end of the second gear 484. A fixing shell 481 for fixing the drive motor 485 is fixedly connected to the bottom surface of the bracket 3.

[0033] Specifically, the car parts are first fitted onto the outer wall of the positioning cylinder 41. Then, the adjusting screw 43 set at the positioning cylinder 41 is rotated, so that under the threaded connection between the adjusting screw 43 and the threaded seat 44, the threaded seat 44 is moved down, thereby gradually opening the control plate 45 set between the threaded seat 44 and the positioning plate 42. That is, the end of the positioning plate 42 with the anti-slip block 5 rotates towards the car parts until the anti-slip block 5 at one end of the positioning plate 42 abuts against the inner wall of the car parts. Under the support of multiple sets of positioning plates 42, the car parts are fixed on the bracket 3.

[0034] Furthermore, after the electronically controlled slider 2 moves the bracket 3 and the automotive parts fixed on the bracket 3 to the painting equipment, the painting equipment first paints the outer surface of the automotive parts and their corresponding positions. After the painting of this part is completed, the drive motor 485 can be turned on, so that the drive motor 485 drives the second gear 484 to rotate. Then, under the meshing of the second gear 484 and multiple sets of first gears 483, the positioning cylinder 41 is driven to rotate, thereby driving the automotive parts fixed at the positioning cylinder 41 to rotate, so that the part of the automotive parts facing away from the painting equipment is rotated to the position corresponding to the automotive parts, so that the outer surface of the automotive parts can be fully painted.

[0035] See attached document Figure 2-3 A connecting component 7 is provided between one end of the electric telescopic rod 6 and the top of the bracket 3. The connecting component 7 is used for the replacement of the electric telescopic rod 6 and the bracket 3. The connecting component 7 includes a sleeve 71 fixedly connected to the top of the bracket 3, a locking block 72 fixedly connected to one end of the electric telescopic rod 6 and engaged with the sleeve 71, and a connecting screw 73 rotatably disposed on one side of the sleeve 71 for locking the sleeve 71 and the locking block 72.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
