Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown:

[0025] The automatic detection mechanism of the metal sheet leveling machine includes a support frame 101 that is fixedly installed on the main body 100 of the leveling machine and is symmetrically arranged;

[0026] The support frame 101 is provided with a connecting block 103, and two sets of connecting blocks 103 are rotatably connected by a rolling element 102 through a bearing.

[0027] A connecting rod 104 is fixedly installed on the top of the connecting block 103, and a connecting plate 105 is fixedly installed between the two sets of connecting rods 104. A movable hole adapted to the connecting rod 104 is opened on the support frame 101, and the connecting rod 104 and the support frame 101 are slidably connected through this movable hole.

[0028] A U-shaped plate 106 is fixedly installed between the two sets of support frames 101;

[0029] On the side of the U-shaped plate 106 and the connecting plate 105 that are close to each other, electromagnet 108 and electromagnet 107 are respectively fixedly installed. Electromagnet 107 and electromagnet 108 are opposite magnetic poles so that they attract each other.

[0030] A laser rangefinder 109 is fixedly mounted on the connecting plate 105 through the opening mounting holes. The laser rangefinder 109 corresponds to the surface of the U-shaped plate 106. A laser rangefinder 2 114 is provided on one side of the U-shaped plate 106. A mounting plate 113 is fixed on the side of the U-shaped plate 106 near the laser rangefinder 2 114. The laser rangefinder 2 114 is fixedly mounted on the mounting plate 113.

[0031] A display screen 112 is installed on the main body 100 of the leveling machine.

[0032] In this implementation scheme: The automatic detection mechanism of the metal sheet leveling machine, during use, first passes the metal sheet to be leveled through the leveling machine body 100 for leveling. After leveling, it moves evenly on the conveyor cylinder (not shown in the figure) of the leveling machine body 100. When the leveled metal sheet moves to the designated position, the laser rangefinder 114's beam is projected onto the upper surface of the leveled metal sheet, thus reducing the measurement distance (originally, the laser rangefinder 114's beam was projected onto the conveyor cylinder of the leveling machine body 100). Subsequently, a signal is sent through the microcontroller (not shown in the figure), which energizes electromagnet 107 and electromagnet 108. Since electromagnet 107... Electromagnet 107 and electromagnet 2 108 are opposite magnetic poles. The magnetic attraction generated by electromagnet 107 and electromagnet 2 108 attracts electromagnet 107 and electromagnet 2 108 to each other. Electromagnet 2 108 is fixed on U-shaped plate 106. U-shaped plate 106 and two sets of support frames 101 are fixed. Connecting plate 105 slides on support frame 101 through two sets of connecting rods 104. As a result, electromagnet 107 moves towards electromagnet 2 108 and drives connecting plate 105 and connecting rods 104 to move upward. Connecting rods 104 drive connecting block 103 and rolling element 102 to move upward synchronously, so that rolling element 102 and conveying cylinder of leveling machine body 100 are separated.

[0033] During this process, the metal plate moves continuously. After electromagnet 107 and electromagnet 2108 are energized for a few seconds, the microcontroller de-energizes electromagnet 107 and electromagnet 2108 (at this time, the rolling element 102 is located above the metal plate). At this time, electromagnet 107 and electromagnet 2108 lose their magnetism. The weight of the rolling element 102 itself drives the connecting rod 104 and the connecting plate 105 to move down synchronously until the rolling element 102 lands on the upper surface of the metal plate.

[0034] As the metal plate is continuously conveyed, the rolling element 102 can roll on the surface of the metal plate. When the metal plate is uneven, the rolling element 102 will fit tightly against the surface of the metal plate due to its own weight, while the connecting rod 104 and the connecting plate 105 move down synchronously. At this time, the distance projected by the laser rangefinder 109 onto the U-shaped plate 106 increases. When the metal plate has a convex surface, the rolling element 102 is lifted up, and the connecting rod 104 and the connecting plate 105 move up synchronously. At this time, the distance projected by the laser rangefinder 109 onto the U-shaped plate 106 decreases. When the distance of the laser rangefinder 109 exceeds the set value, the microcontroller will activate the sound and light alarm 110 to remind personnel to deal with the uneven metal plate.

[0035] This operation automatically performs leveling inspection on the metal sheet after leveling, eliminating the need for manual inspection, reducing the labor intensity of workers, lowering labor costs, improving the efficiency of the entire production line, and meeting actual usage requirements.

[0036] It should be noted that: connect the output signals of laser rangefinder 109 and laser rangefinder 214 to the analog or digital input pins of the microcontroller, connect the control pins of electromagnet 107 and electromagnet 218 to the digital output pins of the microcontroller, connect electromagnet 107 and electromagnet 218 through appropriate power supply and drive circuit (such as relay or transistor) to ensure that the microcontroller can provide sufficient current, and the microcontroller is installed on the leveling machine body 100;

[0037] The solution also includes an electrical control cabinet, which is installed on the main body 100 of the leveling machine. During use, each electrical device can be started and operated through the electrical control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to those in the field, so it will not be elaborated here.

[0038] It should be understood that:

[0039] Furthermore;

[0040] In an optional embodiment, a spring 111 is fixedly installed between the connecting plate 105 and the U-shaped plate 106.

[0041] In this embodiment: by setting spring 111, and spring 111 is in a compressed state, under the action of the rebound force of spring 111, the rolling element 102 can always be in contact with the surface of the metal plate. At the same time, when electromagnet 107 and electromagnet 2 108 are attracted and contacted, a buffering effect can be achieved to avoid collision damage to electromagnet 107 and electromagnet 2 108 due to large impact force.

[0042] Furthermore;

[0043] In an optional embodiment, an audible and visual alarm 110 is fixedly installed on the top of the U-shaped plate 106 to alert to any abnormalities during the leveling process.

[0044] In this embodiment: when the distance of the laser rangefinder 109 exceeds the set value, the microcontroller will activate the sound and light alarm 110 to emit a sound to remind personnel to deal with the uneven metal plate.

[0045] It should be noted that the positive and negative terminals of the audible and visual alarm 110 are connected to the digital output pin of the control unit and the power supply through a relay to drive the audible and visual alarm 110. The display screen 112 is connected to the control unit. The specific use can be flexibly programmed according to the actual use requirements. It can be programmed by conventional means. This programming is an existing mature technology and is well known to those in the art. It will not be elaborated further here.

[0046] The working principle and usage process of this utility model: In use, the automatic detection mechanism of this metal sheet leveling machine first passes the metal sheet to be leveled through the leveling machine body 100 for leveling. After leveling, the sheet moves evenly on the conveyor cylinder (not shown in the figure) of the leveling machine body 100. When the leveled metal sheet reaches the designated position, the laser rangefinder 114 projects its beam onto the upper surface of the leveled metal sheet, thus reducing the measurement distance (originally, the laser rangefinder 114 projected its beam onto the conveyor cylinder of the leveling machine body 100). Subsequently, a signal is sent through the microcontroller (not shown in the figure), which then controls the electromagnets 107 and 108. When energized, electromagnets 107 and 108, being opposite magnetic poles, attract each other magnetically. Electromagnet 107 and 108 are fixed to the U-shaped plate 106, which is also fixed to the two sets of support frames 101. The connecting plate 105 slides on the support frames 101 via two sets of connecting rods 104, causing electromagnet 107 to move towards electromagnet 108. This, in turn, moves the connecting plate 105 and connecting rods 104 upwards. The connecting rods 104 then move the connecting block 103 and the rolling element 102 upwards simultaneously, allowing the rolling element 102 to engage with the leveling machine. The conveying cylinder of the main body 100 creates a gap, while the spring 111 is in a compressed state. During this process, the metal plate moves continuously. After electromagnets 107 and 108 are energized for a few seconds, the microcontroller de-energizes electromagnets 107 and 108 (at this time, the rolling element 102 is located above the metal plate). At this time, electromagnets 107 and 108 lose their magnetism. The weight of the rolling element 102 itself and the compressed spring 111 together drive the connecting rod 104 and the connecting plate 105 to move down synchronously until the rolling element 102 lands on the upper surface of the metal plate. As the metal plate is continuously conveyed, the rolling element 102 can move on the metal plate. When the upper surface rolls, if the metal plate is uneven, the rolling element 102 will fit tightly against the surface of the metal plate due to its own weight when the surface is concave. Meanwhile, the connecting rod 104 and the connecting plate 105 move down synchronously. At this time, the distance projected by the laser rangefinder 109 onto the U-shaped plate 106 increases. When the metal plate has a convex surface, the rolling element 102 is lifted up, and the connecting rod 104 and the connecting plate 105 move up synchronously. At this time, the distance projected by the laser rangefinder 109 onto the U-shaped plate 106 decreases. When the distance of the laser rangefinder 109 exceeds the set value, the microcontroller will activate the audible and visual alarm 110 to sound, reminding personnel to deal with the uneven metal plate.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
