Description

TECHNICAL FIELD

[0001] The present application relates to the field of stamping processing, in particular to a material clamping device with alignment detection function. BACKGROUND

[0002] In the current production of automobile parts, especially in the production process of multi-layer structure parts such as seat back plate and bottom plate, it is often necessary to accurately position two layers of plates. Before stamping, the traditional method mainly relies on some blocks to realize the alignment and clamping of the two layers of plates. Although this method can ensure the accurate butt joint of the plates to a certain extent, it still has many shortcomings. Due to the dimensional deviation of the plates themselves or the wear of the blocks after a long time of use, the positioning accuracy is reduced, which often causes the problem of step edge, as shown in the figure, that is, the uneven edge of the stacked plates, affecting the subsequent processing and assembly accuracy. Figure 1

[0003] In order to make up for this problem, the existing technology usually reserves a certain space for the edge of the plate during design, so as to remove these uneven edges after stacking and processing. However, this method can solve the problem of insufficient positioning accuracy to a certain extent, but it increases the complexity and additional process in the production process, not only increases the production cost, but also affects the production efficiency. Especially in mass production, the design of reserved material width and the subsequent shearing process are particularly cumbersome, which reduces the economy of production.

[0004] If the placement position of the plates can be detected in real time during the production process and the placement position of the plates is adjusted according to the detection result, it will effectively avoid unnecessary edge shearing process. By introducing the alignment detection function, the actual position of the plates can be adjusted before stamping to ensure the positioning accuracy of the stacked plates. This technology not only eliminates the problem of step edge, but also reduces the design amount of plate edge reservation, thereby optimizing the overall production process and reducing production cost.

[0005] Therefore, it is of great significance to develop a material clamping device with alignment detection function. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to at least overcome one of the deficiencies of the prior art, to provide a material clamping device with alignment detection function, which can realize more accurate plate alignment, avoid redundant processes caused by design reservation and shearing, thereby improving production efficiency, reducing production cost and improving the quality of the final product.

[0007] ​To achieve the above object, the application discloses a clamping device with alignment detection function, which comprises a mounting base plate, two horizontally arranged clamping assemblies mounted on the base plate, a horizontal adjustment assembly mounted on the base plate, a visual detection assembly mounted on the base plate, and a controller connected with the visual detection assembly and controlling the work of the clamping assemblies and the horizontal adjustment assembly.

[0008] Further, the opposite surfaces of the fixed block and the movable block are respectively provided with rubber layers.

[0009] Further, the push plate is designed with a convex structure for pushing the edge of the workpiece.

[0010] Compared with the prior art, the application has at least one of the following beneficial technical effects:

[0011] 1. Improved positioning accuracy: By introducing the visual detection assembly and the control system, the clamping device can detect and fine-tune the placement position of the plate in real time, ensuring accurate butt joint of the plate before stamping, avoiding positioning errors caused by size deviation and equipment wear in traditional methods, effectively solving the problem of step edge, and significantly improving the positioning accuracy of the plate in the production process.

[0012] 2. Reducing redundant processes: Through accurate alignment adjustment, the complex process of reserving edges and subsequent shearing due to inaccurate positioning in traditional processes is avoided, reducing unnecessary processing steps and simplifying the production process.

[0013] 3. Reducing production cost: The design of the clamping device can reduce material waste caused by size error, reduce the reserved width of the plate edge and the shearing process, thereby effectively reducing the production cost and improving the production efficiency.

[0025] Referring to the drawings Figures 2-4 The embodiment describes a clamping device with alignment detection function, which is mainly composed of a base plate 1, a clamping assembly 2, a horizontal adjustment assembly 3, a visual detection assembly 4 and a controller (not shown). The design of the device aims to improve production efficiency, reduce production cost and improve the quality of the final product through accurate plate alignment adjustment. The structure, working principle and mutual cooperation mode of each component will be described in detail.

[0026] First of all, the base plate 1 serves as the main body of the clamping device, providing a solid and stable support platform for the installation of other components. The base plate 1 is generally made of aluminum alloy or steel, which has sufficient strength and rigidity to ensure the stability of the installation of each component. The base plate 1 is provided with a plurality of mounting holes for fixing the clamping assembly 2, the horizontal adjustment assembly 3, the visual detection assembly 4 and the controller. All these components are connected to the base plate 1 by bolts to ensure the overall stability of the device.

[0027] The clamping assembly 2 includes a fixed block 201, a movable block 202 and a drive air rod 203. The fixed block 201 and the movable block 202 are respectively arranged on the left and right sides of the base plate 1, and the opposite surfaces are covered with rubber layers. The rubber layer can increase the friction force to prevent the plate from sliding, and at the same time reduce the direct contact between the metal parts to prevent wear. The movable block 202 is hinged to the base plate 1 through a rotating arm, and the front end of the rotating arm is hinged with a pressing block. When the drive air rod 203 extends and retracts, the movable block 202 rotates around the rotating arm, driving the pressing block to approach the fixed block 201, thereby realizing the clamping of the workpiece. The extension and retraction of the air rod 203 is controlled by a valve, which can adjust the air flow in and out through the controller, thereby accurately controlling the action of the drive air rod 203 to drive the movable block 202 to complete the clamping process. The drive air rod 203 is connected with the air source equipment, and the air pressure is provided by the external air source to realize the work. The specific working principle of the drive air rod belongs to the common technology in the pneumatic control system, and the technical personnel can adjust its working parameters according to the needs.

[0028] The horizontal adjustment assembly 3 is installed between the clamping assemblies 2, including an L-shaped push plate 301 and a drive cylinder 302 that drives the horizontal extension of the push plate 301. The push plate 301 is designed with a protruding structure to push the edge of the workpiece, ensuring accurate alignment of the plate. The drive cylinder 302 controls the horizontal extension of the push plate 301, pushing the push plate 301 to adjust the position of the plate in the horizontal direction. Similar to the drive rod 203, the drive cylinder 302 is connected to an external air source and controlled by a valve to ensure accurate operation of the cylinder.

[0029] The visual detection assembly 4 consists of at least one camera and a lighting source, installed on the base plate 1 and arranged horizontally. The lighting source ensures that the edge of the detected workpiece is evenly illuminated, and the camera detects the position of the workpiece by taking pictures. The image processing system transmits the workpiece image captured by the camera to the controller, which determines whether the workpiece is in the predetermined position based on the image information. If the workpiece position deviates, the controller will control the horizontal adjustment assembly 3 to adjust the workpiece position and complete the clamping through the clamping assembly 2. The installation angle and direction of the visual detection assembly 4 can be adjusted through adjustable supports to adapt to different sizes and shapes of workpieces.

[0030] The controller determines the accuracy of the workpiece position by receiving image data from the visual detection assembly 4. Based on the judgment result, the controller adjusts the working state of the clamping assembly 2 and the horizontal adjustment assembly 3 to ensure that the workpiece always remains in the correct position. The controller is connected to the air flow valve of the drive rod 203 and the drive cylinder 302, and adjusts the input and output of air flow to control the extension and retraction of the pneumatic components, thereby accurately adjusting the position of the workpiece. The operation of the controller is usually realized through a pre-set program to ensure that all components work in coordination.

[0031] In actual operation, the camera of the visual detection assembly 4 first scans the position of the workpiece and transmits the image to the controller. The controller determines the deviation of the workpiece through image recognition algorithm and sends a signal to drive the horizontal adjustment assembly 3 to adjust the horizontal position of the workpiece. If the workpiece position deviates greatly, the controller will also send a signal to adjust the clamping assembly 2, driving the movable block 202 to approach the fixed block 201, thereby completing the clamping operation. After the adjustment is completed, the device enters the next processing step.

[0032] The design of the device greatly improves the accuracy of plate positioning, avoids error accumulation in traditional methods, and reduces redundant processes in the production process such as edge cutting, significantly improving production efficiency and reducing costs. Through accurate clamping and alignment adjustment, not only the processing quality of the workpiece is improved, but also the service life of the equipment is prolonged.

[0033] To sum up, the clamp device with alignment detection function provided by the embodiment has the advantages of high efficiency, high accuracy, and high economic efficiency and technical advantages.

[0034] While exemplary embodiments of the disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the disclosure without substantially departing from the spirit and scope of the disclosure. Therefore, all changes and modifications are intended to be included within the scope of the disclosure as defined by the claims.
