Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to the drawings, a distance-setting pressure distance detection apparatus includes: a clamping unit 2 for clamping the workpiece 6, a driving unit 1 for driving the clamping unit 2 to move up and down, and a distance measuring unit 3 for measuring an assembling distance. The clamping unit 2 is connected to the driving unit 1, the distance measuring unit 3 is horizontally aligned to the workpiece 6, and the distance measuring unit 3 is electrically connected with the driving unit 1 through a PLC.

In order to better fix the driving unit 1 and the clamping unit 2, the detection device further comprises a supporting unit 4, the driving unit 1 is arranged on the supporting unit 4, and the driving unit 1 is fixedly supported through the supporting unit 4, so that the stability is improved.

The driving unit 1 comprises a servo motor 11 and a screw rod 12, the screw rod 12 is connected to the servo motor 11, the servo motor 11 drives the screw rod 12 to rotate, and the rotary motion is converted into lifting motion through the screw rod 12.

The driving unit 1 further comprises a linear slide rail 13 and a connecting plate 14, the linear slide rail 13 is arranged in parallel with the screw rod 12, the connecting plate 14 is arranged on the linear slide rail 13, and the connecting plate 14 is connected with the linear slide rail 13 in a sliding manner. The clamping unit 2 is connected with the driving unit 1 through a connecting plate 14, and the clamping unit 2 moves up and down on the linear slide rail 13 under the action of the connecting plate 14.

The clamping unit 2 comprises a clamping jaw cylinder 21 and a pressure sensor 22, wherein the clamping jaw cylinder 21 is positioned above the workpiece 6, and the workpiece 6 is clamped by the clamping jaw cylinder 21. The pressure sensor 22 is disposed above the jaw cylinder 21, and the jaw cylinder 21 is in contact with the pressure sensor 22. The clamping unit 2 further comprises a fixing frame 23, and the clamping jaw cylinder 21 and the pressure sensor 22 are connected with the driving unit 1 through the fixing frame 23.

The ranging unit 3 includes a camera 31 and a light source 32, the camera 31 and the light source 32 are located on the same horizontal plane, and the workpiece 6 is located between the camera 31 and the light source 32. The distance measuring unit 3 further comprises a lifting bracket 33, the camera 31 is arranged on the lifting bracket 33, and the height of the camera 31 can be adjusted through the lifting bracket 33, so that the camera 31 can be always horizontally aligned with the workpiece 6.

In order to avoid that the distance of the up-and-down movement of the clamping unit 2 is too large, the detection device further comprises a limiting unit 5, and the limiting unit 5 is arranged on the supporting unit 4. The limiting unit 5 may adopt a limiting sensor including an upper limiting sensor and a lower limiting sensor, and when the clamping unit 2 moves to the positions of the upper limiting sensor or the lower limiting sensor, respectively, the clamping unit 2 stops moving.

In the actual use process, the camera 31 is used for preliminarily photographing the workpiece 6 in the explorator 7, and the preliminary preassembly distance of the workpiece 6 is determined.

The camera 31 gives a distance signal to the servo motor 11, and the rotation of the servo motor 11 drives the screw rod 12 to rotate, so as to drive the clamping unit 2 to move up and down in the vertical direction. The distance of the up and down movement of the gripping unit 2 is determined by the distance signal fed back to the servo motor 11 by the camera 31 until the gripping unit 2 comes into contact with the workpiece 6 and the workpiece 6 is gripped by the gripper cylinder 21. Then, the servo motor 11 rotates again to drive the clamping jaw air cylinder 21 to move downwards until the workpiece 6 is assembled in a specified qualified distance range, and the assembly precision can reach +/-0.01 mm.

A pressure sensor 22 is fixed on the linear slide rail 13, then a clamping jaw air cylinder 21 is fixed below the center of the pressure sensor 22, and when the clamping jaw air cylinder 21 clamps the workpiece 6 and is assembled downwards, a pressure signal is given to the pressure sensor 22 through reaction force. When the assembling pressure exceeds or does not reach the set range, an alarm signal is given out through the PLC and the action is stopped; when the moving distance of the linear sliding rail 13 exceeds the upper limit sensor and the lower limit sensor, an alarm signal is given through the PLC and the action is stopped.

When the distance assembly pressure and distance detection device completes assembly and pressure test, the PLC gives a signal for completing action to the camera 31, so that the camera 31 can shoot and detect the workpiece 6 at the assembled position again, and whether the current assembly position of the workpiece 6 meets the distance specification or not is judged.

When the assembly distance and the assembly pressure meet the requirements, the distance detection device for the distance assembly pressure gives a qualified signal to inform an operator to continue the next operation, otherwise, the distance detection device gives an alarm to inform and stops acting
