Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of tooling and fixtures, and in particular to a plate-shaped workpiece positioning and correction system. Background Art

[0002] During the quenching process of plate-shaped workpieces, such as scrapers, the workpieces are transported to the unloading point by the unloading mechanism of the quenching machine. Mechanical fixtures then pick up the workpieces, transport them, and complete the workpiece palletizing process. Before the workpieces are unloaded, they must undergo processes such as disassembly of the loading fixture, handling, quenching, and conveying. This causes a slight offset in the position of the workpiece on the unloading mechanism of the quenching machine, affecting the gripping and palletizing capabilities of the unloading fixture. This necessitates secondary positioning of the workpiece before the unloading fixture picks up the workpiece to ensure accurate gripping of the workpiece by the unloading fixture. Currently, automated production lines reposition workpieces using smart cameras to accurately identify their position and adjust fixtures to accommodate them. Alternatively, secondary positioning mechanisms are installed at the unloading point to provide a unified reference point for the workpiece and adjust the workpiece position to accommodate the fixture. However, existing positioning methods still have problems. Smart cameras can accurately identify the two-dimensional or three-dimensional coordinates of workpieces, but the cameras are expensive and the procedures are complex. Later program modeling, modification, and the addition of new workpiece models require specialized technicians, and positioning mechanisms require a reasonable spatial layout. The inability to add positioning mechanisms in some applications where space is limited and installation is unsuitable remains a challenge. Utility Model Content

[0044] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0045] like Figure 1-4 As shown, according to the embodiment of the present application, a positioning and correction system for a plate-shaped workpiece 500 is proposed, comprising: a blanking support table 100, to which the workpiece that has undergone the pre-process is unloaded; a clamp assembly 200, which is used to clamp the workpiece unloaded to the blanking support table 100, and the clamp assembly 200 has the function of adjusting the clamping position laterally and axially; a first laser sensor group 300, the clamp assembly 200 is arranged on the clamp assembly 200, and the output of the first laser sensor group 300 The light direction is perpendicular to the table surface of the blanking support table 100, and the first laser sensor is used to determine the axial offset and lateral offset of the workpiece to be clamped; the second laser sensor group 400, the second laser sensor group 400 is set in the clamp assembly 200 to determine the two side positions of the plate-like workpiece 500, and after the clamping assembly is adjusted according to the feedback data of the first laser sensor, the light emitting direction of the second laser sensor is parallel to the clamping surface of the clamp assembly 200, and the second laser sensor group 400 is used to determine whether the clamp assembly 200 is adjusted into place.

[0046] The plate-shaped workpiece 500 positioning and deviation correction system provided in the embodiment of the present application includes a blanking support platform 100, a fixture assembly 200, a first laser sensor group 300 and a second laser sensor group 400. During use, the plate-shaped workpiece 500 that has completed the pre-process flow of disassembly, handling, quenching, and transportation is transported to the blanking support platform 100. The position of the workpiece will be slightly offset when it is unloaded. Therefore, when unloading the plate-shaped workpiece 500, the two side positions of the plate-shaped workpiece 500 are first determined by the second laser sensor group 400, and the two grasping ends of the fixture assembly 200 are adjusted according to the side positions of the plate-shaped workpiece 500, so that the two ends of the fixture assembly 200 are aligned with the side positions of the plate-shaped workpiece 500. The center point of each gripping end is on the same axis as the center point of the plate-like workpiece 500. The position and rotation angle of the plate-like workpiece 500 are determined by the first laser sensor group 300. The fixture assembly 200 determines the position of the clamped plate workpiece and the clamping angle based on the information detected by the first laser sensor group 300, and adjusts the position of the gripping end of the fixture assembly 200 according to the obtained position information of the plate-like workpiece 500. After the fixture assembly 200 is adjusted and before clamping, the relative position of the gripping end of the fixture assembly 200 and the plate-like workpiece 500 is verified by the second laser sensor group 400. When the verification is correct, the plate-like workpiece 500 is grasped by the gripping end of the clamping assembly.

[0047] This technical solution realizes positioning of the plate-like workpiece 500 through the first laser sensor group 300. Compared with the smart camera, it is cheaper and has a simpler program. It can adapt to plate-like workpieces 500 of different sizes without the need for separate programming according to the workpiece size.

[0048] At the same time, the present technical solution determines the positions of the two sides of the plate-like workpiece 500 through the second laser sensor group 400, and performs secondary verification on the relative position of the adjusted gripping end of the fixture assembly 200 and the plate-like workpiece 500, further increasing the reliability of the present utility model.

[0049] like Figure 1-4 As shown, the blanking support platform 100 includes: a basic platform body 110, which is set on the ground or an installation platform; and support bars 120, two of which are set in parallel to the basic platform body 110.

[0050] In this technical solution, the blanking support platform 100 includes a base platform body 110 and support bars 120 .

[0051] Among them, the base platform 110 is set on the ground or the installation platform, which is used to raise the loading and unloading height, which is convenient for placing the plate work and clamping the plate workpiece 500. The support bar 120 is set on the upper surface of the base platform 110. There are two support bars 120 and they are arranged in parallel on the upper surface of the base platform 110. It can be understood that the spacing between the two support bars 120 should be smaller than the width of the plate workpiece 500. The support bar 120 is used to support the plate workpiece 500 to be clamped, so that the two ends of the plate workpiece 500 are suspended in the air, which is convenient for clamping the plate workpiece 500 through the clamping assembly, further increasing the ease of use of this technical solution.

[0052] like Figure 1-4 As shown, the clamp assembly 200 includes: a Y-axis slide rail 210, two of which are arranged in parallel on both sides of the unloading support platform 100; an X-axis slide rail 220, both ends of which are slidingly connected to the two Y-axis slide rails 210; a steering shaft 230, which is slidingly connected to the X-axis slide rail 220; and a gripper 240, which is rotatably connected to the steering shaft 230.

[0053] In this technical solution, the fixture assembly 200 includes a Y-axis slide rail 210, an X-axis slide rail 220, a steering shaft 230 and a gripper 240, wherein there are two Y-axis slide rails 210, and both Y-axis slide rails 210 are arranged parallel to each other on both sides of the unloading support platform 100. It can be understood that the Y-axis slide rail 210 is arranged parallel to the support bar 120, the two ends of the X-axis slide rail 220 are respectively arranged on the Y-axis slide rail 210, the steering shaft 230 is slidably arranged on the X-axis slide rail 220, and the gripper 240 is rotatably arranged on the X-axis slide rail 220.

[0054] In this embodiment, the first laser sensor group 300 is disposed on the X-axis slide rail 220 .

[0055] During use, the plate-like workpiece 500 is placed on the unloading support table 100. According to the data collected by the second laser sensor group 400, the position of the steering shaft 230 on the X-axis slide rail 220 is adjusted so that the center points of the two grippers 240 are on the same axis as the center point of the plate-like workpiece 500. Then the X-axis slide rail 220 slides on the Y-axis slide rail 210 until it passes the plate-like workpiece 500. The positioning of the plate-like workpiece 500 is achieved by the first laser sensor group 300. According to the data information collected by the first laser sensor group 300, the position of the gripper 240 on the Y-axis and X-axis is adjusted, and the angle is adjusted by the steering shaft 230.

[0056] Subsequently, the relative positions of the gripper 240 and the plate-like workpiece 500 are verified by the second laser sensor group 400. After the verification is correct, the plate-like workpiece 500 is clamped and unloaded by the gripper 240. If the verification fails, the gripper 240 is reset and the previous step is repeated to reposition.

[0057] like Figure 1-4 As shown, the first laser sensor group 300 includes: a left first laser sensor, which is arranged on the gripper 240, and the light emitting direction of the left first laser sensor is perpendicular to the table surface of the blanking support table 100; a right first laser sensor, which is arranged on the gripper 240 and on the right side of the left first laser sensor, and the light emitting direction of the left first laser sensor is perpendicular to the table surface of the blanking support table 100.

[0058] like Figure 1-4 As shown, when the X-axis slide rail 220 slides on the Y-axis slide rail 210 and passes through the plate-like workpiece 500, the coordinate of the left first laser sensor receiving the reflected light from the plate-like workpiece 500 is the first positioning point 610, and the coordinate of the left first laser sensor stopping receiving the reflected light from the plate-like workpiece 500 is the second positioning point 620.

[0059] like Figure 1-4 As shown, when the X-axis slide rail 220 slides on the Y-axis slide rail 210 and passes through the plate-like workpiece 500, the coordinates of the light reflected from the plate-like workpiece 500 received by the right first laser sensor are the third positioning point 630, and the coordinates of the light reflected from the plate-like workpiece 500 stopped by the right first laser sensor are the fourth positioning point 640.

[0060] In this technical solution, the gripper 240 is adjusted by the data collected by the second laser sensor group 400 so that the symmetry axis of the gripper 240 passes through the center point of the plate-like workpiece 500. The first laser sensor group 300 includes a left first laser sensor and a right first laser sensor. The left first laser sensor and the right first laser sensor are respectively arranged at the lower end of the X-axis, and the light output direction is perpendicular to the upper surface of the blanking support table 100. When the X-axis slide 220 moves on the Y-axis slide 210, the left first laser sensor and the right first laser sensor will pass by the plate-like workpiece 500. When the light output of the left first laser sensor is blocked by the plate-like workpiece 500, a first signal mutation will occur. Set this position as the first positioning point 610, record the coordinates of the first positioning point 610 as (X1, Y1), a second signal mutation occurs when the light output of the left first sensor is out of the obstruction of the plate-like workpiece 500, record the coordinates of the second positioning point 620 as (X1, Y2), a first signal mutation occurs when the light output of the right first laser sensor is blocked by the plate-like workpiece 500, set this position as the third positioning point 630, record the coordinates of the third positioning point 630 as (X2, Y3), a second signal mutation occurs when the light output of the right first laser sensor is out of the plate-like workpiece 500, set this position as the fourth positioning point, record the coordinates of the fourth positioning point 640 as (X2, Y3).

[0061] According to the coordinates of the first positioning point 610 to the fourth positioning point 640, the deflection angle of the plate-like workpiece 500 can be calculated as arctan((Y2-Y1) / (X2-X1)), and the coordinates of the center point of the plate-like workpiece 500 are (X2-X1), (Y1+Y4) / 2. According to the coordinates of the center point of the plate-like workpiece 500 and the deflection angle, the grasping clamp 240 can be corrected.

[0062] like Figure 1-4 As shown, it also includes: a processor, which is electrically connected to the clamp assembly 200, the first laser sensor group 300, and the second laser sensor group 400, and the processor is used to receive the coordinate information of the first positioning point 610, the second positioning point 620, the third positioning point 630 and the fourth positioning point 640, obtain the center point and rotation angle of the plate-like workpiece 500 to be grasped according to the coordinate information, and control the clamp assembly 200 to adjust the position and angle according to the obtained information before grasping.

[0063] In this technical solution, it is electrically connected to the first laser sensor group 300 , the second laser sensor group 400 and the fixture assembly 200 .

[0064] During use, the processor collects data sent back by the second laser sensor, and uses the data to control the steering shaft 230 to run on the X-axis slide 220 and adjust its position, and then controls the X-axis slide 220 to run on the Y-axis slide 210, so that the X-axis slide 220 drives the first sensor group to pass through the plate-like workpiece 500, and collects the data sent back by the first sensor group to calculate the center point coordinates and deflection angle of the plate-like workpiece 500, and then controls the steering shaft 230 to rotate according to the center point coordinates and deflection angle of the plate-like workpiece 500, and then collects data from the second laser sensor group 400 for secondary verification of the relative position of the plate-like workpiece 500 and the gripper 240. After the data is lower than the deviation threshold, the plate-like workpiece 500 is clamped by the gripper 240.

[0065] like Figure 1-4 As shown, the second laser sensor group 400 includes: two second laser sensors, the two second laser sensors are respectively set on the X-axis slide rail 220, and after the fixture assembly 200 is adjusted, the two second laser sensors are electrically connected to the processor.

[0066] In this technical solution, the plane on which the vertical blanking support table 100 is placed is set as the first plane. First, the fixture assembly 200 determines the two side edges of the projection of the plate-like fixture on the first plane through the second laser sensor, and records the coordinate of the first side on the X-axis as X3, and records the coordinate of the second side on the X-axis as X4. Then, the X-axis coordinate of the center point of the plate-like workpiece 500 is (X4-X3) / 2. According to the obtained X-axis coordinate of the center point of the plate-like workpiece 500, the position of the steering shaft 230 on the X-axis is adjusted so that the symmetry axis plane of the gripper 240 is also at the X-axis coordinate. After adjusting the position and angle of the gripper 240 according to the data fed back by the first laser sensor group 300, the second laser sensor group 400 is used to verify whether the plate-like workpiece 500 is in the same plane as the gripping surface of the gripper 240, and whether the distances between the two side edges of the plate-like workpiece 500 and the corresponding gripper 240 are the same. If the error is lower than the threshold, the gripper 240 grips the plate-like workpiece 500. If the error is higher than the threshold, the plate-like workpiece 500 is repositioned.

[0067] like Figure 1-4 As shown, the blanking support platform 100 also includes: a first sliding member, which is fixedly arranged on the base table, and the support bar 120 is slidably connected to the first sliding member; the sliding direction of the support bar 120 realized by the first sliding member is perpendicular to the support bar 120.

[0068] In this technical solution, the distance between the two support bars 120 can be adjusted by the first sliding member. By setting the first sliding member, the support bars 120 can be adapted to plate-like workpieces 500 of different widths.

[0069] like Figure 1-4 As shown, the first laser sensor group 300 further includes: a second sliding member, and the first laser sensor group 300 is connected to the fixture assembly 200 through the second sliding member.

[0070] In this technical solution, the distance between the two laser sensors of the first laser sensor group 300 can be adjusted by the second sliding member. Through this setting, the first laser sensor group 300 can be adapted to plate-like workpieces 500 of different widths.
