Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, and in particular to a precision positioning pressing device. Background Technology

[0002] In the automated pressing production of workpieces such as automotive door panels, the edge banding is pre-treated to form grooves during pressing. Currently, robotic arms are commonly used for loading and unloading workpieces in the processing.

[0003] However, robotic arms have inherent limitations in grasping, handling, and placing workpieces: First, the clamping force of the robotic arm's end effector (such as a fixture) may cause local deformation of thin-walled or easily deformable workpieces (such as car doors); second, at the moment of placement, the workpiece may experience slight slippage or rebound when it comes into contact with the bearing surface (such as a base plate); third, the robotic arm's own repeatability error and the accuracy drift that may occur during long-term operation will cause an initial position offset when the workpiece is placed at the preset station. Although this offset is small, it will be significantly amplified in the subsequent pressing process that requires high-precision positioning, directly causing inaccurate pressing position and deviation of the bending line from the preset trajectory, seriously affecting the dimensional accuracy, shape consistency, and overall quality of the product. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, this utility model is proposed.

[0005] The purpose of this invention is to provide a precise positioning pressing device, which solves the problem of insufficient precision in the pressing process caused by the initial position offset of the workpiece (including sliding, deformation and angular deviation) due to the loading and unloading of the robotic arm.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a precise positioning pressing device, including a base plate, a mounting plate is provided on the top of the base plate, a plurality of electromagnets are provided in the inner cavity of the mounting plate, a pressing component is provided on the upper surface of the base plate, a baffle is fixedly connected to the upper surface of the base plate, linear components are provided on both sides of the mounting plate, a pushing component is provided at the moving end of the linear component, and a correction component is also provided on both sides of the mounting plate;

[0007] The pushing component can push the pressing component towards the baffle, and the correction component is driven by the linear component and can push the pressing component completely into the pressing range.

[0008] As a preferred embodiment of the precise positioning pressing device of this utility model, the pressing assembly includes a column disposed on the upper surface of the base plate, a pressing plate slidably disposed on the column, a positioning plate disposed directly below the pressing plate, a fixing frame disposed on the upper surface of the base plate, and an electric push rod disposed between the fixing frame and the pressing plate.

[0009] In a preferred embodiment of the precise positioning pressing device of this utility model, the positioning plate is located between the baffle and the mounting plate.

[0010] As a preferred embodiment of the precise positioning pressing device of this utility model, the linear component includes a slide rail disposed on the upper surface of the base plate, a slider slidably disposed on the slide rail, and a cylinder disposed between the slider and the base plate.

[0011] As a preferred embodiment of the precise positioning pressing device of this utility model, the pushing component includes a push plate disposed on the slider and a reinforcing rib disposed at the corner of the push plate.

[0012] As a preferred embodiment of the pressing device for precise positioning of this utility model, the correction component includes: upright plates disposed on both sides of the mounting plate, a slide rod slidably disposed on the upright plates, a limiting plate disposed on the slide rod, a correction plate disposed at the other end of the slide rod, a spring disposed between the limiting plate and the upright plates, a triangular plate disposed between the correction plate and the limiting plate, and a connecting plate disposed between the slider and the triangular plate.

[0013] The advantages of this precision positioning pressing device are as follows: It uses an electromagnet embedded in the mounting plate to generate a controllable adsorption force to fix the workpiece, eliminating the disturbances, deformations, and slippage caused by gripping and releasing during the traditional robotic arm gripping process, ensuring initial placement stability; combined with a fixed baffle as an absolute physical reference, the pushing component pushes the workpiece close to the baffle, achieving precise longitudinal positioning and avoiding the influence of robotic arm positioning errors; and the linear component drives the correction component to push the workpiece close to the baffle laterally to the pressing center, eliminating any residual offset that may occur during the pushing process in real time, ensuring that the workpiece is completely and accurately located within the pressing range.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0023] Example 1

[0024] Reference Figure 1 This is the first embodiment of the present utility model. This embodiment provides a precise positioning pressing device, including a base plate 1, a mounting plate 2 is provided on the top of the base plate 1, a plurality of electromagnets 3 are provided in the inner cavity of the mounting plate 2, a pressing component 4 is provided on the upper surface of the base plate 1, a baffle 5 is fixedly connected to the upper surface of the base plate 1, linear components 6 are provided on both sides of the mounting plate 2, a pushing component 7 is provided at the moving end of the linear component 6, and a correction component 8 is also provided on both sides of the mounting plate 2.

[0025] The pushing component 7 can push the pressing component towards the baffle 5, and the correction component 8 is driven by the linear component 6 and can push the pressing component completely into the pressing range.

[0026] It should be noted that a mounting plate 2 is fixedly connected to the upper surface of the base plate 1. Several electromagnets 3 are embedded in the mounting plate 2. The magnetic strength of the electromagnets 3 is affected by the current. In the pushing and correction state, the magnetic force of the electromagnets 3 only needs to generate a slight magnetic force on the car door. A pressing component 4 is provided on the upper surface of the base plate 1. The pressing component 4 can press the car door and perform preliminary bending along the preset area. A baffle 5 is also fixedly connected to the upper surface of the base plate 1. The baffle 5 has a blocking effect. When the pushing component 7 pushes the car door, and the top of the car door is restricted by the baffle 5, it means that the car door has accurately reached the preset area. A correction component 8 is set on the measuring of the mounting plate 2. The correction component 8 is driven by the linear component 6 and can push the car door towards the mounting plate 2 so that it is within the pressing range.

[0027] In use, place the door workpiece to be pressed on the mounting plate 2 area on the upper surface of the base plate 1, activate several electromagnets 3 in the inner cavity of the mounting plate 2 to generate a slight magnetic force, and initially attract and fix the door workpiece to the surface of the mounting plate 2. At this point, the magnetic force only needs to ensure that the workpiece does not move arbitrarily, facilitating subsequent operations. The linear components 6 on both sides of the mounting plate 2 drive the pushing components 7 on their moving ends. The pushing components 7 move, pushing the door workpiece adsorbed on the mounting plate 2 along the upper surface of the base plate 1 towards the baffle 5. The door workpiece continues to move under the action of the pushing components 7 until its top or designated positioning edge contacts the baffle 5 fixed on the base plate 1. The baffle 5 acts as a hard limit, preventing the workpiece from moving further, indicating that the workpiece has initially reached the preset positioning area. At the same time that the pushing components 7 complete the pushing and the workpiece contacts the baffle 5, the correction components 8 on both sides of the mounting plate 2 start to work, pushing the door workpiece that is already against the baffle 5 along a direction perpendicular to the pushing direction, precisely moving it into place, so that it is completely within the effective working area of ​​the pressing component 4. After confirming that the workpiece has been limited by the baffle 5 and pushed by the correction components 8, and accurately positioned in the preset area, the pressing component 4 set on the upper surface of the base plate 1 is activated. The pressing component 4 performs pressing operations on the precisely positioned door workpiece, and performs bending and other processing along the preset area.

[0028] In summary, by using the electromagnet 3 embedded in the mounting plate 2 to generate a controllable adsorption force to fix the workpiece, the disturbances, deformations, and slippage caused by gripping and releasing during the gripping and releasing process of traditional robotic arms are eliminated, ensuring initial placement stability. Combined with the fixed baffle 5 as an absolute physical reference, the pushing component 7 pushes the workpiece close to the baffle 5, achieving precise longitudinal positioning and avoiding the influence of robotic arm positioning errors. Furthermore, the linear component 6 drives the correction component 8 to push the workpiece close to the baffle 5 laterally to the pressing center, eliminating any residual offset that may occur during the pushing process in real time, ensuring that the workpiece is completely and accurately located within the pressing range.

[0029] like Figure 2 As shown, in a preferred embodiment, the pressing assembly 4 includes a column 41 disposed on the upper surface of the base plate 1, a pressing plate 42 slidably disposed on the column 41, a positioning plate 43 disposed directly below the pressing plate 42, a fixing frame 44 disposed on the upper surface of the base plate 1, and an electric push rod 45 disposed between the fixing frame 44 and the pressing plate 42.

[0030] Positioning plate 43 is located between baffle 5 and mounting plate 2.

[0031] It should be noted that the column 41 is installed on the upper surface of the base plate 1, and a pressing plate 42 is slidably connected to the column 41. A positioning plate 43 that is adapted to the pressing plate 42 is provided on the lower surface of the pressing plate 42. The positioning plate 43 is fixedly installed between the baffle 5 and the mounting plate 2. The distance between the groove of the pressing plate 42 and the baffle 5 is the edge width. A fixing frame 44 is also fixedly connected to the base plate 1. Several electric push rods 45 are connected between the fixing frame 44 and the pressing plate 42. The extension of the electric push rods 45 drives the pressing plate 42 to squeeze the edge of the door to form an edge groove.

[0032] like Figure 4 As shown, in a preferred embodiment, the linear component 6 includes a slide rail 61 disposed on the upper surface of the base plate 1, a slider 62 slidably disposed on the slide rail 61, and a cylinder 63 disposed between the slider 62 and the base plate 1.

[0033] It should be noted that a slide rail 61 is fixedly connected to the upper surface of the base plate 1, and a slider 62 is slidably connected to the slide rail 61. A cylinder 63 is provided between the slider 62 and the base plate 1. The slider 62 slides on the slide rail 61 by extending and retracting the cylinder 63.

[0034] like Figure 4 As shown, in a preferred embodiment, the push assembly 7 includes a push plate 71 disposed on the slider 62 and a reinforcing rib 72 disposed at the corner of the push plate 71.

[0035] It should be noted that the push plate 71 is fixedly installed on the slider 62. The slider 62 slides, which drives the push plate 71 to move, thereby pushing the car door. Furthermore, the reinforcing rib 72 at the corner of the push plate 71 can increase the strength of the push plate 71.

[0036] like Figure 3 As shown, in a preferred embodiment, the correction assembly 8 includes upright plates 81 disposed on both sides of the mounting plate 2, a slide rod 82 slidably disposed on the upright plate 81, a limiting plate 83 disposed on the slide rod 82, a correction plate 84 disposed at the other end of the slide rod 82, a spring 85 disposed between the limiting plate 83 and the upright plate 81, a triangular plate 86 disposed between the correction plate 84 and the limiting plate 83, and a connecting plate 87 disposed between the slider 62 and the triangular plate 86.

[0037] It should be noted that the upright plate 81 is fixedly connected to the upper surface of the base plate 1. Several sliding rods 82 are slidably connected to the upright plate 81. The two ends of the sliding rods 82 are respectively fixedly connected to the limiting plate 83 and the correction plate 84. A spring 85 is provided between the limiting plate 83 and the upright plate 81. A triangular plate 86 is provided between the correction plate 84 and the limiting plate 83. The triangular plate 86 is connected to the slider 62 through the connecting plate 87. When the slider 62 slides, it will drive the triangular plate 86 to move through the connecting plate 87. The inclined side of the triangular plate 86 will press the correction plate 84 towards the mounting plate 2, thereby pushing the door into the pressing range.
