[0029] The model of infrared distance measuring sensor 38 is GP2Y0A02YK0F infrared distance measuring sensor, which can accurately measure the position of movable block 34, so as to judge the position of the object to be pasted.

[0030] The working principle is as follows:

[0031] First, during use, the object to be pasted is sent to the front of the robot arm 41 via the feeding conveyor 43, and the robot arm 41 grabs and places the object to be pasted onto the top of the support plate 35.

[0032] Second, start the electric push rod 36. The electric push rod 36 pushes the clamping block 37 to move. The object to be pasted is fixed by the cooperation of the clamping block 37 and the support plate 35. Start the motor 32. The motor 32 drives the screw 33 to rotate. When the screw 33 rotates, it drives the movable block 34 to move. When the movable block 34 moves, it drives the object to be pasted to move. The position of the movable block 34 is detected by the infrared distance sensor 38, so as to determine the position of the object to be pasted.

[0033] Third, use laser scanner 26 to inspect the surface of the object to be pasted to determine whether the surface is flat. If it is flat, motor 4 32 controls the movable block 34 to move and drive the object to be pasted to continue moving. If it is not flat, start motor 1 22. Motor 1 22 drives screw 1 23 to rotate. When screw 1 23 rotates, it drives movable plate 25 to move. When movable plate 25 moves, it drives grinding block 28 to move. Start motor 22 to drive grinding block 28 to rotate. Grind the object to be pasted with grinding block 28 to make its surface flat.

[0034] Fourth, after the sanding is completed, control the movable block 34 to move and drive the object to be pasted to continue moving. When the object to be pasted moves under the cleaning roller 299, start the motor 3 298. The motor 3 298 drives the rotating rod 296 to rotate. When the rotating rod 296 rotates, it drives the cleaning roller 299 to rotate. When the cleaning roller 299 rotates, it cleans the surface of the object to be pasted. After cleaning is completed, the laser scanner 26 judges whether the surface is flat and clean. If it is flat, continue to the next step. If it is not flat, return to the sanding block 28 to continue sanding.

[0035] Fifth, when the object to be pasted moves to the dispensing machine 210, the dispensing machine 210 drips epoxy resin onto the top of the object to be pasted, and then controls the movement of the object to be pasted so that it moves to the bottom of the pressure plate 213.

[0036] Sixth, when the object to be bonded moves under the pressure plate 213, start the robot arm 2 42, and use the robot arm 2 42 to place the high temperature strain gauge of the feeding conveyor 2 44 onto the glue of the object to be bonded. Start the electric push rod 1 211, and the electric push rod 1 211 pushes the pressure plate 213 to squeeze the high temperature strain gauge, so that the high temperature strain gauge is fully bonded to the object to be bonded.

[0037] Seventh, when the pasting is completed, the pasted object is sent to the discharge conveyor 45 by the manipulator 42 to complete the discharge, that is, the pasting is completed.

[0038] The control mode of the utility model is controlled by manually starting and closing the switch, and the wiring diagram of the power element and the provision of the power supply are common knowledge in the art, and the utility model is mainly used for protecting the mechanical device, so the control mode and the wiring arrangement of the utility model will not be explained in detail.
