The application provides a thickness measurement device. As shown in fig. 1, a thickness measuring apparatus 100 according to an embodiment of the present disclosure includes a first driving device 110, a first clamping assembly 120, a second driving device 130, a second clamping assembly 140, and a sensor assembly 150. For convenience of description, the X direction, the Y direction, and the Z direction shown in fig. 1 are defined in the present application, and the X direction, the Y direction, and the Z direction are perpendicular to each other, and the Z direction is a first direction and may also be referred to as an up-down direction, the X direction is a second direction and may also be referred to as a front-back direction, and the Y direction is a third direction and may also be referred to as a left-right direction.
The first clamping assembly 120 is coupled to an output of the first driving device 110, and the first driving device 110 can drive the first clamping assembly 120 to move along a first direction to clamp the workpiece 101. As shown in fig. 1, in the embodiment of the present application, the workpiece 101 is a plate material to be cut, and in other embodiments, the thickness measuring apparatus 100 of the present application can also measure the thickness of other types of workpieces 101. The second driving device 130 is connected to an output terminal of the first driving device 110. The second clamping assembly 140 is connected to an output end of the second driving device 130, the second clamping assembly 140 is driven by the second driving device 130 to move at least along the first direction, and the second clamping assembly 140 is used for cooperating with the first clamping assembly 120 to clamp the workpiece 101 to be measured.
When the thickness measuring apparatus 100 of the present application performs thickness measurement, when the workpiece 101 has not moved to the thickness measuring apparatus 100, that is, when the thickness measuring apparatus 100 is in an initial state, as shown in fig. 1 to 3, the first clamping assembly 120 and the second clamping assembly 140 are separated by a certain distance in the first direction (Z direction), so that enough space is reserved for the workpiece 101 to move between the first clamping assembly 120 and the second clamping assembly 140; when the workpiece 101 moves, the first driving device 110 operates, the first driving device 110 drives the first clamping component 120 and the second driving device 130 to move together along the first direction, so that the first clamping component 120 approaches the workpiece 101, and the first clamping component 120 abuts against one surface of the workpiece 101, as shown in fig. 7; then, the second driving device 130 is operated, and the second driving device 130 drives the second clamping assembly 140 to move towards the first clamping assembly 120 along the first direction until the second clamping device abuts against the other surface of the workpiece 101, as shown in fig. 8, so that the second clamping assembly 140 and the first clamping assembly 120 together clamp the workpiece 101. The thickness of the plate can be calculated according to the distance that the second clamping assembly 140 moves in the first direction under the driving of the second driving device 130. And the sensor assembly 150 is used to detect the distance that the second clamping device is moved in the first direction by the second driving device 130.
In one embodiment of the present application, as shown in fig. 1, the first driving device 110 drives the first clamping assembly 120 to move downward, and the second driving device 130 drives the second clamping assembly 140 to move upward, so that the first clamping assembly 120 and the second clamping assembly 140 jointly clamp the workpiece 101. In other embodiments, the first driving device 110 may drive the first clamping assembly 120 to move upward, and the second driving device 130 drives the second clamping assembly 140 to move downward, so that the first clamping assembly 120 and the second clamping assembly 140 jointly clamp the workpiece 101. That is, the structure shown in fig. 1 is inverted upside down, the first driving device 110 and the first clamping assembly 120 are located below, and the second driving device 130 and the second clamping assembly 140 are located above, and the effects of clamping the workpiece 101 and detecting the thickness of the workpiece 101 can be similarly achieved.
In the application, the thickness of the workpiece 101 can be measured only by two driving devices, the structure is simple, the cost is low, the thickness of the workpiece 101 can be calculated by measuring the distance of the second clamping device moving along the first direction under the driving of the second driving device 130, and the measurement result is accurate.
In one embodiment, the second clamping assembly 140 can be configured to rotate, that is, the second driving device 130 can not only drive the second clamping assembly 140 to move along the first direction, as shown in fig. 7 and 8, but also drive the second clamping assembly 140 to rotate around the rotation axis 102, wherein the rotation axis 102 is parallel to the first direction. For example, the second driving means 130 employs a rotary cylinder, so that the second clamping assembly 140 is driven to move and rotate when the piston of the second driving means 130 is extended and rotated. As shown in fig. 7 and 8, when the second driving means 130 is a rotary cylinder, the rotation axis is a central axis of a piston of the rotary cylinder. The benefits of the second clamping assembly 140 being able to rotate are: as shown in fig. 2 and 7, when the second clamping assembly 140 is not clamping the workpiece 101, it can rotate to a position parallel to the Y direction, i.e. on one side of the workpiece 101, so as not to interfere with the movement of the workpiece 101 to the detection position; as shown in fig. 8, when the second clamping assembly 140 needs to clamp the workpiece 101, the second clamping assembly 140 is rotated to a position parallel to the X direction, such that the second clamping assembly 140 is located at a position directly below the first clamping assembly 120, i.e., such that the second clamping assembly 140 is located below the workpiece 101, and the second clamping assembly 140 is vertically opposite to the first clamping assembly 120, such that the second clamping assembly 140 clamps the workpiece 101 together with the first clamping assembly 120 to measure the thickness of the workpiece 101.
The second driving device 130 may be not only a rotary cylinder but also other driving devices that can simultaneously perform linear driving and rotary driving. Thus, in summary, the second driving device 130 includes a linear driving portion capable of driving the second clamping assembly 140 to move along the first direction, and a rotary driving portion capable of driving the second clamping assembly 140 to rotate around the rotation axis 102, wherein the rotation axis 102 is parallel to the first direction.

In the embodiment of the present application, as shown in fig. 3, the displacement sensor 151 is disposed at the output end of the first driving device 110, the detection rod 152 is disposed at the output end of the second driving device 130, the displacement sensor 151 and the main body of the second driving device 130 are relatively fixed, when the output end of the second driving device 130 drives the second clamping component 140 to move upward to clamp the workpiece 101, the detection rod 152 is also driven by the output end of the second driving device 130 to move upward, the displacement sensor 151 can detect the displacement of the detection rod 152, thereby indirectly detecting the displacement of the second clamping component 140, and further calculating the thickness of the workpiece 101.
As shown in fig. 1 and 3, the thickness measuring device 100 of the present application further includes a mounting plate 103. One end (i.e., the rear end) of the mounting plate 103 in the second direction (X direction, i.e., the front-rear direction) is connected to the output end of the first driving device 110, the first clamping assembly 120 is disposed at the other end (i.e., the front end) of the mounting plate 103 in the second direction, and the second driving device 130 is disposed at the end (i.e., the rear end) of the mounting plate 103 connected to the output end of the first driving device 110.
