Description

Technical Field

[0001] The utility model relates to the technical field of plate detection equipment, in particular to a mechanical precision plate thickness detection device. Background Art

[0002] Traditional plate thickness detection requires manual operation, and usually requires the use of measuring tools (such as micrometers, vernier calipers, etc.) for measurement. This method requires the operator to have certain skills and experience, and is susceptible to human errors; and the detection requires measurement at each position, which is time-consuming and limits its application in large-scale production. For production lines that require high efficiency and high precision, traditional methods may not meet the needs. In particular, for large-area plates or workpieces with complex shapes, it takes more time and human resources; usually only limited discrete points can be measured, and continuous plate thickness distribution information cannot be provided. This method cannot accurately capture the unevenness or local deformation of the plate surface; due to the limitations of manual operation and measuring tools, traditional plate thickness detection is susceptible to error accumulation. These errors may come from factors such as inaccurate measurements by operators, wear or imprecision of tools, resulting in inaccurate final measurement results. Utility Model Content

[0005] The upper surface of the base is located outside the column assembly end and is fixed with an angle code for increasing the structural strength by bolts.

[0006] One end of the resistive linear displacement sensor is fixed on the sensor mounting plate by means of screws, and the other end of the resistive linear displacement sensor is fixedly mounted on the cylinder mounting plate.

[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Figure 1 and Figure 2 The mechanical precision plate thickness detection device shown includes a base 1, a column 2 is fixedly installed on the upper surface of the base 1, a column end cover 3 is fixedly installed on the top of the column 2, a cylinder mounting plate 4 is fixedly installed on the outer side of the column 2, an upper ball bearing 6 and a lower ball bearing 7 are respectively installed on the outer side of the cylinder mounting plate 4 through two horizontally arranged ball bearing fixing blocks 5, a sensor mounting plate 9 for assembling a resistive linear displacement sensor 8 is arranged on the outer side of the cylinder mounting plate 4, a cylinder 10 for controlling the resistive linear displacement sensor 8 is installed on the outer side of the cylinder mounting plate 4, and a pressure regulating valve 11 and a solenoid valve 12 that cooperate with the cylinder 10 are fixedly installed on the back of the column 2.

[0021] The pressure regulating valve 11 and the solenoid valve 12 are both prior art and are used to adjust the lifting and lowering of the cylinder 10 and control the gas pressure.

[0022] In order to improve the structural strength of the column, an angle code 13 for increasing the structural strength is fixed on the upper surface of the base 1 at the outer side of the assembly end of the column 2 by bolts.

[0023] In order to cooperate with distance detection, one end of the resistive linear displacement sensor 8 is fixed to the sensor mounting plate 9 by screws, and the other end of the resistive linear displacement sensor 8 is fixedly mounted on the cylinder mounting plate 4.

[0024] One end of the resistive linear displacement sensor 8 is a signal transmitting end, and the other end is a signal receiving end.

[0025] In order to cooperate with the installation and fixing, the cylinder mounting plate 4 is fixed to the front side wall of the column 1 by means of the mounting plate fixing piece 14 screws.

[0026] In order to cooperate with the air guide, the air delivery port of the cylinder 10 is fixedly connected to the solenoid valve 12 through an external flexible air guide pipe 15.

[0027] In order to cooperate with the lifting and lowering adjustment, the ball bearing fixing block 5 at the connection end of the upper ball bearing 6 is fixedly assembled with the front side wall of the cylinder mounting plate 4, and the ball bearing fixing block 5 at the connection end of the lower ball bearing 7 is fixedly assembled with the upper surface of the sensor mounting plate 9.

[0028] The present application is an auxiliary device for detecting different plate thicknesses in an automated bending unit. After the robot picks up the plate from the loading rack, it sends the plate to be detected between the upper ball bearing 6 and the lower ball bearing 7, triggering the sensor in the prior art. The solenoid valve 12 controls the cylinder 10 to move upward, and at the same time drives the high-precision resistive linear displacement sensor 8 for detection. The detection method of the resistive linear displacement sensor 8 is to lift and squeeze the sensor mounting plate 9 to the lower surface of the plate, and then calculate the thickness of the plate through the value change of the resistive linear displacement sensor 8. If it is within the set travel range, the plate thickness meets the requirements, and the robot performs the next step, using the plate translation to transport, so as to detect the thickness of the entire plate; if it is not within the set travel range, the plate is placed in the defective product area, and the plate thickness is detected and fed back to the system in real time to detect whether the plate thickness is within the specified plate thickness range, to ensure that the thickness of the same batch of plates is consistent, thereby ensuring the accuracy requirements of bending.
