Description

Technical Field

[0001] The present application relates to the field of automatic control technology, and in particular to a device and system for automatically detecting the limit position of a steel plate on a transverse platform. Background Art

[0002] A transfer system is a device that moves automobile bodies from one production line to another. Because different processes require different equipment and types of work, a transfer system is needed to move automobile bodies to the next production line for the next step. A transfer system is essential equipment in automotive production lines. It significantly improves production efficiency, reduces waiting time between production lines, and enhances production line flow.

[0003] According to the different properties of the transverse moving platform, it can be divided into many types. Classification by transverse moving method According to the different transverse moving methods, the transverse moving platform can be divided into two types: horizontal moving type and vertical moving type. Horizontal moving type: The vehicle body moves horizontally along the ground between different processes. The advantages of this transverse moving platform are fast moving speed and easy operation, but it requires more factory space. Vertical moving type: The vehicle body is moved vertically by a lift between different processes. This transverse moving platform can save space, but the moving speed is relatively slow. Classification by transportation method According to the different transportation methods, the transverse moving platform can be divided into two types: manual transverse moving platform and automatic transverse moving platform. Manual transverse moving platform: Workers are required to manually push the vehicle body to move, which is suitable for small factories or production lines. The disadvantage is low work efficiency. Automatic transverse moving platform: It can automatically complete the transverse movement of the vehicle body, and can adjust the direction and docking position of the vehicle body as needed, thereby improving work efficiency.

[0004] At the edge limit position of the transverse table, laser limiters are often used to determine whether the steel plate has actually reached the limit position. Due to the limitations of the laser limiter and the influence of on-site environmental factors, the following problems may occur: First, the on-site environment is dusty and easily blocks the laser, affecting the detection function of the laser limiter, affecting the production rhythm and reducing production efficiency; second, mechanical equipment is damaged; third, the steel plate rises and falls and vibrates, requiring frequent adjustment of the laser position of the laser limiter, increasing labor costs.

[0030] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0031] A transfer system is a device that moves automobile bodies from one production line to another. Because different processes require different equipment and types of work, a transfer system is needed to move automobile bodies to the next production line for the next step. A transfer system is essential equipment in automotive production lines. It significantly improves production efficiency, reduces waiting time between production lines, and enhances production line flow.

[0032] According to the different properties of the transverse moving platform, it can be divided into many types. Classification by transverse moving method According to the different transverse moving methods, the transverse moving platform can be divided into two types: horizontal moving type and vertical moving type. Horizontal moving type: The vehicle body moves horizontally along the ground between different processes. The advantages of this transverse moving platform are fast moving speed and easy operation, but it requires more factory space. Vertical moving type: The vehicle body is moved vertically by a lift between different processes. This transverse moving platform can save space, but the moving speed is relatively slow. Classification by transportation method According to the different transportation methods, the transverse moving platform can be divided into two types: manual transverse moving platform and automatic transverse moving platform. Manual transverse moving platform: Workers are required to manually push the vehicle body to move, which is suitable for small factories or production lines. The disadvantage is low work efficiency. Automatic transverse moving platform: It can automatically complete the transverse movement of the vehicle body, and can adjust the direction and docking position of the vehicle body as needed, thereby improving work efficiency.

[0033] In order to achieve the safety interlocking of the limit positions of the transverse platform, the required limits are often measured using laser limiters. Although this can meet the normal detection function, it will cause the laser limiters to be affected by external environmental factors. There is a lot of dust on site, which blocks the laser, affecting the detection function of the laser limiters, affecting the production rhythm, and reducing production efficiency. At the same time, when the crane puts the steel plate into the transverse platform, the steel plate rises and falls and vibrates the ground, causing the laser position of the laser limiter to deviate. Subsequently, manpower is required to frequently adjust the laser position of the laser limiter, increasing labor costs.

[0034] A proximity switch is a position detection device that operates without direct mechanical contact with moving parts. Currently, they are widely used in the field of automatic control, particularly in metallurgical automation. In practice, when an object moves within the detection range of the proximity switch, the switch emits a signal, detecting the object's position and enabling precise control of its movement. The typical detection distance for a proximity switch is 1-10 mm. This means that the switch emits a detection signal when the mechanical equipment moves within 1-10 mm of the proximity switch.

[0035] Based on this, the present application provides a device and system for automatically detecting the limit position of steel plates on a transverse platform. The lever principle is used to ensure that the steel plate stops in time when it is transported to the edge position during transverse transportation, thereby avoiding the steel plate from rushing out of the transverse platform, avoiding collision and wear between the proximity switch and mechanical equipment, and extending the service life of the proximity switch. At the same time, the laser limit is changed to a proximity switch to ensure the stable operation of the on-site transverse platform and achieve the purpose of reducing costs and increasing efficiency.

[0036] In some embodiments, Figure 1 As shown, the present application provides a device for automatically detecting the limit position of a steel plate by a transverse platform, characterized in that the device includes:

[0037] A lever fixing base 1, to which a pair of lever fixing brackets 2 are fixedly connected;

[0038] The lever fixing bracket 2 fixes the lever bearing 4. One end of the lever bearing 4 is connected to the first lever 3, and the other end is connected to the second lever 5. The second lever 5 is welded to the long steel pipe 6.

[0039] The long steel pipe 6 is clamped by two L-shaped metal plates 7, wherein the L-shaped metal plates 7 are provided with holes;

[0040] The proximity switch fixing bracket 9 is fixed to the L-shaped metal plate 7 , and the proximity switch 8 is fixed on the proximity switch fixing bracket 9 and can pass through the position of the opening hole of the L-shaped metal plate.

[0041] The lever fixing base 1 is used to support the lever fixing bracket 2, and the L-shaped metal plate 7 is used to support the proximity switch fixing bracket 9. Through this design, the transverse platform automatic detection steel plate limit position device can be stably fixed on the wall equipment.

[0042] One end of the lever bearing 4 is connected to the first lever 3 , and the other end is connected to the second lever 5 . The second lever 5 is welded to the long steel pipe 6 .

[0043] By adopting the above technical solution, as soon as the steel plate is pressed down, the second lever 5 is lifted, driving the long steel pipe 6 away from the detection range, ensuring that it has reached the limit position.

[0044] The present application adopts the design of a lever fixing base 1, a lever fixing bracket 2, a first lever 3, a second lever 5, a lever bearing 4, a long steel pipe 6, an L-shaped metal plate 7, a proximity switch 8, and a proximity switch fixing bracket 9, so that when the steel plate reaches the limit position, it can respond in time, and change the laser limit to a proximity switch, thereby reducing the influence of the detection element on the environment such as dust and light, and reducing the probability of failure. Instead of requiring manpower to adjust the laser limit position, the detection element position is fixed in advance with a bracket, and it can be directly installed without adjusting the position, thereby reducing labor costs, improving replacement efficiency, and simplifying the installation process.

[0045] The hole of the L-shaped metal plate 7 has the same diameter as the proximity switch 8 .

[0046] The long steel pipe 6 is placed in the movable channel between the two L-shaped metal plates 7 , and the distance between the two L-shaped metal plates 7 matches the diameter of the long steel pipe 6 .

[0047] By adopting the above technical solution, the long steel pipe 6 can move translationally in the space between the two L-shaped metal plates 7 .

[0048] In some embodiments, the device further comprises:

[0049] The stopper 10 is fixed at the head position of the two L-shaped metal plates 7 as a transverse limiting component of the long steel pipe 6.

[0050] By adopting the above technical solution, the long steel pipe 6 can be stopped in time at the detection position and will not leave the detection position due to inertia.

[0051] In some embodiments, the proximity switch 8 is a sensor.

[0052] In this embodiment, the fastener comprises a fixing bolt, and the proximity switch mounting bracket is provided with a screw hole that matches the bolt. During use, the bolt is loosened and the proximity switch 8 is inserted into the bracket. The long steel pipe 6 is lowered to the position of the stopper 10. The distance between the proximity switch 8 and the long steel pipe 6 is adjusted to 5 mm. The bolt is tightened to secure the proximity switch 8. This ensures that the proximity switch 8 is fixed in the desired position and detects the long steel pipe 6 when the long steel pipe is lowered to the stopper 10.

[0053] In actual use, when the steel plate presses down the first lever 3 during movement, the second lever 5 is subsequently lifted, driving the long steel tube 6 to lift up. The long steel tube 6 leaves the detection range of the proximity switch 8, indicating that the steel plate has reached its limit position. When the steel plate does not press down the first lever 3, the long steel tube 6 droops and abuts against the stopper 10, remaining within the detection range of the proximity switch 8, indicating that the steel plate has not reached its limit position.

[0054] In some embodiments, Figure 2 As shown, the present application also provides a system for automatically detecting the limit position of steel plates on a transverse platform, the system comprising:

[0055] The device for automatically detecting the limit position of the steel plate by the transverse moving stand described in the above embodiment;

[0056] The transverse platform 11 is connected to the transverse platform automatic detection steel plate limit position device through the lever fixing bracket 2; the controller is used to send control instructions.

[0057] like Figure 2 In the figure, the automatic detection device of the steel plate limit position of the transverse platform is connected to the transverse platform 11 through the lever fixing bracket 2 and is arranged on the side of the transverse platform 11.

[0058] It can be seen from the above embodiments that the present application provides a device and system for automatically detecting the limit position of steel plates on a transverse platform, and the device includes: a lever fixing base, the lever fixing base is fixedly connected to a pair of lever fixing brackets; the lever fixing bracket fixes the lever bearing, one end of the lever bearing is connected to the first lever, and the other end is connected to the second lever, and the second lever is welded to a long steel pipe; the long steel pipe is clamped by two L-shaped metal plates, wherein a hole is provided on the L-shaped metal plate; the proximity switch fixing bracket is fixed on the L-shaped metal plate, and the proximity switch is fixed on the proximity switch fixing bracket and can pass through the position of the opening hole of the L-shaped metal plate. This application uses the design of a lever fixing base, a lever fixing bracket, a lever, a lever bearing, a long steel pipe, an L-shaped metal plate, a proximity switch, a proximity switch fixing bracket, and a block to enable a timely response when the steel plate reaches the limit position, and changes the laser limit to a proximity switch, thereby reducing the impact of the detection element on the environment such as dust and light, and reducing the probability of failure.
