Description

[0003] Although steel door panels have high strength, they have inherent defects such as insufficient rigidity at the edges, susceptibility to scratches, and difficulty in sealing. The edge rolling process fundamentally improves the durability and resistance to damage of the door, allowing the door panel to fit more tightly with the door frame. This helps save energy and create a more comfortable indoor environment. Under current technology, the structural dimensions of the panel itself need to be inspected before edge rolling.

[0035] The detection component 12 includes a mounting base 13. A fixing plate 14 is mounted on the front end of the mounting base 13. The upper surface of the fixing plate 14 is at the same level as the upper vertex of the roller 2. The mounting base 13 is fixedly connected to the mounting groove. A gear 15 is set inside the mounting base 13. A rack 16 is set on one side of the gear 15. A detection plate 17 is fixedly mounted in the middle of the rack 16. The rack 16 meshes with the gear 15 and is slidably connected to the mounting base 13. A micro motor 18 is mounted on one side of the two sets of support plates 8. The output end of the micro motor 18 passes through the support plate 8 and the mounting base 13 in sequence and is connected to the gear 15. A micro motor 2 (not shown in the figure) is mounted on the outside of the detection component 12 mounted on the frame 1. The output end of the micro motor 2 is connected to the gear 15 of the detection component 12 on the frame 1. Encoders (not shown in the figure) are mounted on the output ends of the motor 11, the motor 21, the micro motor 18, and the micro motor 2.

[0036] Please see Figure 1 , Figures 6-8 A pressure roller 20 is positioned near the right end of the roller 2. The two ends of the pressure roller 20 are connected to bearings on the frame 1. A motor 3 (not shown in the figure) is mounted on the outer side of one set of the frame 1. The output shaft of the motor 3 is connected to one end of the pressure roller 20, and the other end of the pressure roller 20 passes through the frame 1. A trapezoidal groove 21 is formed on the left side of the pressure roller 20's shaft, and an arc-shaped groove 22 is formed on the right side of the shaft. Both the trapezoidal groove 21 and the arc-shaped groove 22 are annular grooves. A guide groove 23 and a guide groove 24 (e.g., ...) are formed on the shaft between the trapezoidal groove 21 and the arc-shaped groove 22 on the pressure roller 20's shaft. Figure 6 and Figure 7 As shown), guide groove 23 is close to trapezoidal groove 21, guide groove 24 is close to arc groove 22, and there is a distance between guide groove 23 and guide groove 24. Trapezoidal ring 25 and arc ring 26 are sleeved on the shaft of pressure roller 20. Trapezoidal ring 25 and arc ring 26 are slidably connected to guide groove 23 and guide groove 24 respectively. The overall shape of trapezoidal ring 25 and arc ring 26 is circular. The outer ring of trapezoidal ring 25 is machined with a trapezoidal ring groove with the same structure as trapezoidal groove 21, and the outer ring of arc ring 26 is machined with an arc ring groove with the same structure as arc groove 22.

[0037] A pressure roller 27 is positioned directly above the pressure roller 1 20. The two ends of the shaft of the pressure roller 27 are connected to the bearing seats of the frame 1 respectively. A trapezoidal boss 28 is machined on the left side of the shaft of the pressure roller 27, and an arc-shaped boss 29 is machined on the right side of the shaft. A guide groove 30 and a guide groove 41 are provided on the shaft of the pressure roller 27 between the trapezoidal boss 28 and the arc-shaped boss 29. The guide groove 30 is close to the trapezoidal boss 28, and the guide groove 41 is close to the arc-shaped boss 29. A trapezoidal ring 22 and an arc-shaped ring 23 are fitted on the shaft of the pressure roller 27. The trapezoidal ring 22 and the arc-shaped ring 23 are circular in shape and are slidably connected to the guide groove 30 and the guide groove 41 respectively. The outer ring of the trapezoidal ring 22 is machined with a shaft platform with the same structure as the trapezoidal boss 28, and the outer ring of the arc-shaped ring 23 is machined with a shaft platform with the same structure as the arc-shaped boss 29.

[0038] A drive belt 34 is provided on the outside of the shaft of the pressure roller 20 that passes through the frame 1. The two ends of the drive belt 34 are respectively installed in conjunction with the shafts of the pressure roller 20 and the pressure roller 27.

[0039] The shafts of pressure roller 1 20 and pressure roller 2 27 both pass through the central area of ​​square frame 9. Trapezoidal ring 1 25 and arc ring 1 26 are both located between square frame 9 and movable frame 1 901. Trapezoidal ring 2 32 and arc ring 2 33 are both located between square frame 9 and movable frame 2 902. Square frame 9 does not contact pressure roller 1 20 and pressure roller 2 27.

[0040] The following is a supplementary explanation based on the above structure: Trapezoidal groove 21, trapezoidal ring 1 25, trapezoidal boss 28, and trapezoidal ring 2 32 are located to the left of pressure roller 1 20 and pressure roller 2 27, respectively. Since pressure roller 2 27 is located directly above pressure roller 1 20, trapezoidal edge curling of the panel is achieved on the left side of each set of pressure rollers. Similarly, arc-shaped edge curling of the panel is achieved on the right side of each set of pressure rollers. By using pressure roller 1 20 and pressure roller 2 27, different edge curling requirements of two sets of panels of the same specification can be achieved simultaneously, effectively increasing production efficiency.

[0041] Example 1: Two sets of panels to be rolled are simultaneously placed above the roller conveyor. The roller conveyor transports the panels from the left roller 2 to the right roller. The working principle of the roller conveyor is the existing technology. The control module sends synchronization commands to motor 4 and motor 11. Motor 4 and motor 11 drive shaft 3 and shaft 10 to rotate, respectively. Since shafts 3 and 10 each have two sets of threads with different directions of rotation, shafts 3 and 10 drive the baffle 5 and the square frame 9 to move synchronously in opposite directions. The support plate 8 is connected to the baffle 5 and the square frame 9 at both ends, so the baffle 5, the support plate 8 and the square frame 9 move synchronously. The moving principle is the same as the screw drive principle. The baffle 5 drives the arc plate 7 to move synchronously. Since the arc directions of the two sets of arc plates 7 are different, the two sets of arc plates 7 push the two sets of panels to move to the left and right respectively. The roller conveyor continuously conveys the panels. Between the left end roller 2 and the pressure roller 20, the left and right sides of the panel are limited by the mounting seats 13 of each set of detection components 12 installed on the support plate 8 and the frame 1.

[0042] The encoder detects the number of rotations of motor 4 and motor 11. The encoder transmits the rotation count signals of each group of motors to the control module. The control module calculates the moving distance of baffle 5, support plate 8 and square frame 9. Cross-validation is achieved by comparing the data of motor 4 and motor 11. Since the frame 1 is fixed, the width of the panel is the distance between support plate 8 and each group of detection components 12 on the frame 1 minus the moving distance of support plate 8. Due to production requirements, the panel is cut before the edge-rolling process. Therefore, the width of the panel to be edge-rolled should be a known value. The panel width is detected by comparing the known width with the actual detection value. Limiting components are used to limit the panels of different sizes.

[0043] Example 2: Based on Example 1, for example, when processing trapezoidal hemming, since trapezoidal ring 25 is located between square frame 9 and movable frame 901, and trapezoidal ring 32 is located between square frame 9 and movable frame 902, when square frame 9 moves, it pushes trapezoidal ring 25 and trapezoidal ring 32 to the left respectively. When square frame 9 stops moving, square frame 9, movable frame 901, and movable frame 902 achieve axial limiting of trapezoidal ring 25 and trapezoidal ring 32. The control module sends a working command to motor 3, which drives pressure roller 20 to rotate clockwise. Pressure roller 20 drives transmission belt 34 to rotate, and transmission belt 34 transmits the rotation to pressure roller 27, causing pressure roller 27 to rotate counterclockwise (e.g., Figure 11As shown), pressure roller 1 20 and pressure roller 27 drive trapezoidal groove 21 and trapezoidal boss 28 to rotate synchronously. Since trapezoidal ring 1 25 and trapezoidal ring 22 are slidably connected to guide groove 1 23 and guide groove 30 respectively, trapezoidal ring 1 25 and trapezoidal ring 22 rotate with each group of pressure rollers. Since in embodiment 1, baffle 5, support plate 8 and square frame 9 realize the limitation of the panel to be rolled, the square frame 9 is in a prohibited state. Under the limiting action of square frame 9 and each group of movable frames (such as... Figure 9 As shown), to prevent trapezoidal ring 25 and trapezoidal ring 32 from moving along the axis, ensuring the accuracy of the crimping;

[0044] The roller conveyor continuously transports the panel towards the pressure roller 20, conveying the panel to be rolled towards the pressure roller. The trapezoidal groove 21 and the trapezoidal boss 28 cooperate (e.g. Figure 10 As shown), trapezoidal ring 25 and trapezoidal ring 32 work together to achieve edge rolling on both sides of the panel. The processing principle of arc edge rolling is the same as that of trapezoidal edge rolling.

[0045] Example 3: The width of the panel was indirectly detected through Example 1, but the panel itself was not detected. Therefore, if there are processing problems with the panel itself, it may affect the edge rolling operation in Example 2.

[0046] Specifically, in scenario one: the panel width is acceptable, but the thickness of one side of the panel to be rolled is larger than that of the other side. During the rolling process, the thicker side requires a larger bending force and the thinner side requires a smaller bending force. However, the pressure rollers apply pressure simultaneously, which may result in the thicker side not being fully formed while the thinner side is already over-bent, reducing the finished product qualification rate. Therefore, during the panel conveying process, the panel thickness is detected by each set of detection components 12 to ensure that the rolling process is qualified.

[0047] After the limiting components complete the panel's limiting, the control module starts each set of micro motors. Each set of micro motors drives gear 15 to rotate, and gear 15 drives rack 16 to move along mounting base 13. When gear 15 drives rack 16 to move towards fixed plate 14, rack 16 drives detection plate 17 to move synchronously, reducing the distance between detection plate 17 and fixed plate 14. The control module controls each set of micro motors to ensure that the distance between detection plate 17 and fixed plate 14 reaches the maximum allowable thickness of the panel. When the roller conveyor transports the panel, if the thickness on one side of the panel exceeds the allowable error value, the panel's movement path is blocked by detection plate 17, and the panel cannot move to the processing position. This avoids the production of defective products and prevents the unqualified panel itself from causing additional processing burden on the edge-rolling device, effectively reducing maintenance costs and improving product qualification rate.

[0048] Scenario 2: The thickness on both sides of the panel is less than the minimum thickness within the tolerance range, which can easily lead to excessive bending of the thin edge, resulting in wrinkles, folds, or surface damage from the mold, reducing the finished product qualification rate. The panel thickness can be detected by the detection component 12.

[0049] If the test in Case 1 is qualified, each group of micro motors will continue to drive the gear 15 to rotate, thereby causing the test plate 17 to continue to move closer to the fixed plate 14. When the distance between the test plate 17 and the fixed plate 14 is less than the minimum thickness, it indicates that the thickness of the panel is unqualified. The test principle is the same as that in Case 1. Panels with excessively small thickness should be recycled.

[0050] Scenario 3: If the processing of the panel to be rolled is qualified, but there is a defect in the processing of the center of the panel, the pass rate may also be reduced. For example, if the processing of the two sides of the panel to be rolled is qualified, but the structure of the center area of ​​the panel is thicker or thinner, it may cause the panel to bend near the center area, making the overall panel appear as a convex or concave shape. When the panel bends, the height position of the edge to be rolled changes, which may lead to misjudgment in Scenario 1 and Scenario 2. Therefore, the curvature of the panel surface is detected by laser detector 19 and laser receiver 1901, and the detection results of Scenario 1 and Scenario 2 are cross-validated.

[0051] When the roller conveyor transports the panel past the laser detector 19, the laser detector 19 emits a laser, and the laser receiver 1901 receives the laser. The laser receiver 1901 determines whether the panel itself is bent based on the percentage of the received laser that is blocked by the panel. If the percentage of the received laser that is blocked is greater than one-quarter, it indicates that the panel is bent. A secondary processing is performed through the previous cutting process. After the secondary processing, the edge is rolled again. If the panel still fails the test after the secondary processing, it indicates that there is a certain fault in the cutting process, and the fault in the cutting process should be investigated.

[0052] Scenario 4: Changes in external ambient temperature can cause thermal expansion and contraction of the panel, which may cause the panel to bend. For example, during the panel cutting process, the temperature of the cut part of the panel rises. When the panel is transported to the bending device, changes in ambient temperature may cause the panel to bend unpredictably. Therefore, based on Scenario 3, the operation should be suspended for a period of time, and the bending test should be performed again when the panel temperature reaches a balanced state to eliminate temperature interference and improve the accuracy of the test.
