Description

Technical Field

[0001] This utility model belongs to the technical field of automotive manufacturing automation equipment, and in particular relates to an automatic material feeding mechanism for automotive frame production lines. Background Technology

[0002] In the automotive nail frame production process, long strips of profiles need to be transported to the nail frame station for assembly. Currently, most production lines still use manual feeding, where workers must move stacked profiles one by one onto the conveyor track. This is not only labor-intensive and inefficient, but also prone to affecting the subsequent nail frame accuracy due to misalignment of the profiles. A few automated feeding devices suffer from complex structures and poor adaptability, making it difficult to accommodate different specifications of automotive nail frame profiles. Furthermore, they lack stable feeding and positioning mechanisms, causing profiles to easily shift or jam during the feeding process, affecting the continuity of the production line.

[0003] Chinese patent application CN215100442U discloses a non-standard terminal feeding mechanism, including a turntable, a positioning fixture disposed on the turntable and capable of positioning the device to be fed, and a first feeding mechanism, a second feeding mechanism, and a third feeding mechanism sequentially distributed along the rotation path of the turntable. The first feeding mechanism can receive first terminals one by one and feed them onto the device to be fed; the second feeding mechanism can receive second terminals one by one and feed them onto the device to be fed; the third feeding mechanism can receive third terminals one by one and feed them onto the device to be fed. In this embodiment, the turntable simplifies the feeding operation of different terminals, helps to improve the feeding efficiency of terminals, and the turntable also enables the compact distribution of the first, second, and third feeding mechanisms, thus reducing the space occupied by the non-standard terminal feeding mechanism.

[0004] While this patented method uses manual sorting combined with a simple conveyor track for terminal loading, enabling initial matching and assembly of terminals with the devices to be loaded, this approach requires dedicated personnel for terminal sorting, assembly, and calibration of positioning deviations. This multi-person division of labor not only increases labor costs but also easily leads to loading interruptions due to inconsistent operating rhythms, making it difficult to improve overall production efficiency and impossible for a single person to operate the entire production line.

[0005] To address these issues, we provide an automatic profile feeding mechanism for automotive nail frame production lines. Utility Model Content

[0006] The purpose of this invention is to provide an automatic feeding mechanism for profiles in an automotive nail frame production line. By combining a cylinder and a vacuum suction cup, it solves the problem of low feeding efficiency in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an automatic profile feeding mechanism for an automotive nail frame production line. It includes a frame with a material frame slidably connected to the top. An oven is located on one side of the material frame, and an upper pressure plate is located on the other side. A feeding assembly is located inside the material frame, comprising a movable frame. Both sides of the bottom of the movable frame are slidably connected to the frame, and cylinders are fixedly connected to both sides of the movable frame. Push rods are slidably connected to the inner cavity of each cylinder, and vacuum suction cups are fixedly connected to the bottom of each push rod. The assembly uses two cylinders and two vacuum suction cups to ensure consistent action when the vacuum suction cups grip the profiles, preventing profile tilting or detachment due to unilateral force, and further improving the stability of gripping and conveying. Multiple suction holes are provided on the surface of the vacuum suction cups, allowing for a more uniform negative pressure distribution when the vacuum suction cups contact the profile surface, avoiding localized force concentration caused by single-point suction, further enhancing gripping stability and preventing profile deflection during conveying.

[0009] The present invention is further configured such that the bottom of the upper pressure plate is fixedly connected to the frame, the top of the upper pressure plate is fixedly connected to a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a lower pressure plate, and both sides of the lower pressure plate are slidably connected to the frame. The hydraulic cylinder drives the lower pressure plate to move, and the output pressure is stable and controllable. The clamping force can be flexibly adjusted according to the stacking state of the profiles in the material frame, which ensures that the profiles are reliably limited and avoids disorder during feeding.

[0010] The present invention is further configured such that a sliding rod is fixedly connected to the bottom of the frame, the surface of the sliding rod is slidably connected to the lower pressure plate, the sliding rod is fixedly connected to the frame and provides independent guide support for the lower pressure plate, which can further limit the lifting trajectory of the lower pressure plate and prevent it from lateral deviation or shaking when moving up and down.

[0011] The present invention is further configured such that a control box is provided on one side of the material frame, and one side of the control box is fixedly connected to the frame. The fixed connection between the control box and the frame avoids the loosening of the wiring or damage to the box body caused by collision or displacement when placed independently, thereby improving the structural stability of the control components.

[0012] The present invention is further configured such that a support rod is fixedly connected to the bottom of the frame, and there are multiple support rods. The multiple support rods can evenly distribute the weight of the frame, the upper material frame, and the feeding assembly to the ground, avoiding deformation or damage caused by excessive local stress on the frame, and significantly improving the overall structural stability of the equipment.

[0013] The present invention is further configured such that a slide rail is fixedly connected to the top of the frame, and the top of the slide rail is slidably connected to the mobile frame. As a dedicated guide component, the slide rail can provide precise motion trajectory constraints for the mobile frame, effectively preventing lateral deviation or jamming of the mobile frame when it slides horizontally.

[0014] The present invention is further configured such that a grid is fixedly connected to one side of the frame, and there are multiple grids. The multiple grids can form a partition protection for the equipment movement area on one side of the frame, effectively preventing operators from accidentally touching moving parts and greatly improving the operational safety of the equipment.

[0015] The present invention has the following beneficial effects.

[0016] 1. The feeding component of this utility model is slidably connected to the frame at the bottom of the movable frame, and can move stably along the preset trajectory to avoid misalignment of the profile due to movement deviation during the feeding process. The cylinders on both sides drive the push rod to ensure that the vacuum suction cup is subjected to balanced force and can maintain a stable posture for transfer after grabbing the profile. The vacuum suction cup grabs the profile and achieves flexible contact through negative pressure adsorption. Compared with mechanical clamping, it will not cause damage such as squeezing or scratches to the surface of the profile. It is especially suitable for irregular profiles with coatings, platings or thin walls.

[0017] 2. The cylinder-driven automated gripping and conveying structure in the feeding assembly of this utility model replaces manual handling actions and reduces repetitive manual labor; the coordinated action of the moving frame and the cylinder can realize continuous operation of gripping, conveying and placing, avoiding feeding interruptions caused by differences in the rhythm of manual operation, improving the continuity of the feeding process, and the action logic of each component is clear, making fault diagnosis easy. Daily maintenance only requires periodic checks on the lubrication status of sliding parts and the sealing of suction cups, reducing equipment maintenance costs and downtime.
