Description

Technical Field

[0001] The invention relates to the technical field of artificial board quality detection, and in particular to an intelligent automatic detection system for artificial board quality. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the current quality detection technology of artificial boards, it is necessary to knock on the artificial boards, and then use the detection elements to detect various characteristics or qualities of the artificial boards. In the current detection technology, it is necessary to manually carry the artificial boards to be detected to the set position, and then manually knock on the artificial boards through tools, and then detect the artificial boards through multiple laser displacement sensors arranged above the artificial boards or acceleration sensors bonded to the surface of the artificial boards. When the above technology is adopted, the artificial boards cannot be accurately positioned at the designated knocking positions when knocking on the artificial boards, so it has a great impact on the detection results, resulting in inaccurate detection results, and even affects the repeatability of the detection process. The knocking force applied manually is random in direction and strength, which will also affect the accuracy of the detection results and the repeatability of the detection industry. The above situations are not conducive to the quality detection of artificial boards. Moreover, the artificial boards to be detected are manually transported to the detection position, which has high labor intensity and low efficiency.

A switch valve is provided on the pipeline to control the conduction and disconnection of the pipeline. The nozzle is fixed to one side of the first sensor storage rack 10-3 through a nozzle bracket and is arranged toward the first sensor storage rack 10-3.

[0109] A blocking mechanism is also provided below the discharge side of the first part. The setting method of the blocking mechanism is the same as that of the blocking mechanism in the detection and transmission mechanism, and will not be described in detail here.

[0110] A glue dissolving agent spraying mechanism 11, a grinding mechanism 12 and a cleaning mechanism 13 are sequentially arranged above the first part.

[0111] The glue dissolving spraying mechanism 11, the grinding mechanism 12 and the cleaning mechanism 13 are all fixed on a frame 15, and the frame 15 is arranged across the first part and fixed on the ground foundation.

[0112] like Fig. 20 As shown, the glue dissolving agent spraying mechanism 11 includes a telescopic component fixed to the axis of the frame and arranged vertically, the telescopic component adopts an electric telescopic rod 11-1, the telescopic part of the electric telescopic rod 11-1 is connected to the nozzle 11-2, the nozzle is connected to the glue dissolving agent barrel through a pipeline and a pump, and the nozzle is provided with a distance sensor 11-3 to detect the distance between the nozzle 11-2 and the artificial board.

[0113] like Fig.21 As shown, the grinding mechanism 12 includes a telescopic component installed on a frame, the telescopic component adopts an electric telescopic rod 12-1, the telescopic part of the electric telescopic rod 12-1 is connected to the grinding tool 12-2, the grinding tool 12-2 adopts a grinding roller, one end of the grinding roller is connected to a grinding drive motor, the grinding drive motor is installed on a connecting frame, the other end of the grinding roller is rotatably connected to the connecting frame, the connecting frame is fixedly connected to the telescopic part of the electric telescopic rod 12-1, the grinding drive motor drives the grinding roller to rotate, the grinding roller contacts the surface of the artificial board, and grinds the surface of the artificial board, further, a pressure sensor 12-3 is provided between the telescopic part of the electric telescopic rod and the connecting frame.

[0114] like Fig. 22 As shown, the cleaning mechanism 13 includes a telescopic component installed on a frame, the telescopic component adopts an electric telescopic rod 13-1, the telescopic part of the electric telescopic rod 13-1 is connected with a cleaning tool 13-2, the cleaning tool 13-2 adopts a cleaning roller, one end of the cleaning roller is connected to a cleaning drive motor, the cleaning drive motor is installed on a connecting frame, the other end of the cleaning roller is rotatably connected to the connecting frame, the connecting frame is fixedly connected to the telescopic part of the electric telescopic rod, a brush is provided on the roller surface of the cleaning roller, the cleaning drive motor drives the cleaning roller to rotate, the brush contacts the surface of the artificial board, and cleans the artificial board film, and a distance sensor 13-3 is provided on the connecting frame for detecting the distance between the cleaning roller and the artificial board.

[0115] By setting up the glue dissolving agent spraying mechanism 11, the grinding mechanism 12 and the cleaning mechanism 13, the surface of the artificial board after inspection can be cleaned without manual cleaning, which reduces the labor intensity of the staff and saves labor costs.

[0116] The working method of the artificial board detection system of this embodiment is:

[0117] The second horizontal linkage mechanism works, so that the sensor seat pick-up and placement mechanism moves to the top of the lower end of the second sensor seat storage rack, the second telescopic component extends, the second clamping mechanism works, clamps a new sensor seat, the second telescopic component resets, the second horizontal linkage mechanism works, and the sensor seat pick-up and placement mechanism moves to the target position, and then the flip drive drives the second clamping mechanism, the rotating motor, and the torque sensor to flip 180°, the second clamping mechanism is set upward, so that the screw of the sensor seat is set upward, and then the six-axis industrial robot arm drives the turntable to move, so that the first clamping mechanism holding the acceleration sensor moves to the target position, at this time the acceleration sensor cooperates with the screw of the sensor seat, and then the rotating motor drives the sensor seat to rotate, and at the same time the second telescopic component extends cooperatively, and the acceleration sensor and the sensor seat are threadedly connected through the screw, and when the torque sensor detects that the torque reaches the set value, the assembly of the acceleration sensor and the sensor seat is completed.

[0118] The artificial board to be inspected is conveyed to the inspection station through the feeding conveyor mechanism and the inspection conveyor mechanism. The blocking mechanism drives the baffle to rise above the power roller conveyor line. When the artificial board contacts the baffle and detects that the pressure sensor on the baffle reaches the set value, the positioning of the artificial board along the conveying direction is completed. The horizontal motion drive mechanism drives the baffle to separate from the artificial board, and then the first lifting component drives the baffle to reset. The clamping drive mechanism drives the two clamping plates to move towards each other to align the artificial board. At this time, the positioning of the artificial board perpendicular to the conveying direction is completed. The six-axis industrial robot drives the turntable to move to the set position above the artificial board, and the first telescopic component drives the turntable down to the target The turntable rotates until the dispensing machine moves to above the fixed position of the acceleration sensor, and the cylinder connected to the dispensing machine works to drive the dispensing machine down until the distance sensor reaches the set value. Then the dispensing machine works to dispense glue on the artificial board. After the dispensing is completed, the turntable rotates to make the first clamping mechanism holding the acceleration sensor rotate to above the fixed position of the acceleration sensor. The first clamping mechanism is driven by the electric telescopic rod to which it is connected until the pressure sensor or the tension and compression sensor reaches the set value, and the sensor seat is bonded to the artificial board. The first clamping mechanism releases the acceleration sensor, the six-axis industrial robot arm is reset, and the turntable leaves the position above the artificial board.

[0119] The second lifting component drives the lifting rod to rise, so that the artificial board is separated from the power roller conveyor line.

[0120] The first horizontal two-axis linkage mechanism drives the vibration applying mechanism to move to the set position, and the hydraulic cylinder is adjusted to extend so that the vibration applying cylinder descends to the target position. The vibration applying cylinder drives the knocking head to move to knock the artificial board.

[0121] The quality inspection of artificial boards is realized through the detection value of acceleration sensor.

[0122] After the detection is completed, the second lifting component drives the lifting rod to descend, and the artificial board returns to the detection and transmission mechanism. The clamping drive mechanism rises to the set height under the drive of the lifting mechanism, and the clamping plates move in opposite directions under the action of the clamping drive mechanism. Then the lifting mechanism drives the clamping drive mechanism to descend, and the two clamping plates press the edge of the artificial board to ensure that the artificial board and the acceleration sensor will not move during the separation process. The six-axis industrial robot drives the turntable to move to the set position, and the first clamping mechanism on the turntable descends under the action of the electric telescopic rod. The first clamping mechanism clamps the acceleration sensor, and then the electric telescopic rod shrinks to separate the sensor seat of the acceleration sensor from the artificial board to wait for the next artificial board to be detected. After the acceleration sensor is detached, the clamping plates are reset under the drive of the clamping drive mechanism and the lifting mechanism.

[0123] After the inspection, the artificial board is transported to the first part of the discharging conveyor mechanism through the inspection conveying mechanism. The blocking mechanism blocks the advancement of the artificial board. The electric telescopic rod drives the nozzle, grinding tool and cleaning tool to descend. The nozzle is used to spray glue dissolving agent to the artificial board. The blocking mechanism descends, the artificial board continues to move forward, the grinding tool is used to grind the surface of the artificial board, and the cleaning tool is used to clean the surface of the artificial board, and the inspected artificial board is sent out through the second part.

[0124] After the sensor seat is used for a set number of times, the sensor seat is removed from the acceleration sensor using the sensor seat placement mechanism and then placed into the high end of the first sensor seat storage rack. The sensor seat slides down along the strip support plate until it contacts the sensor seat in front or the baffle.

[0125] The artificial board detection system of the present embodiment is used to convey the artificial board to be detected to the detection and transmission mechanism through the feeding and conveying mechanism, and there is no need to manually transfer the artificial board to the detection station, which improves work efficiency and reduces labor intensity. At the same time, through the setting of the blocking mechanism and the clamping and centering mechanism, the position of the artificial board on the detection and transmission mechanism can be accurately positioned, so the vibration applying mechanism can accurately position the knocking position of the artificial board. The artificial board is knocked by the vibration applying mechanism, and the force and direction of each knock are the same. Compared with manually knocking the artificial board during each inspection, the detection accuracy is improved and the quality of the artificial board is guaranteed. Moreover, an acceleration sensor installation mechanism is provided on one side of the feeding end of the detection and transmission mechanism, and a sensor seat transfer mechanism is provided on one side of the acceleration sensor installation mechanism, which realizes automatic installation of the acceleration sensor on the artificial board to be detected, and there is no need to manually install and disassemble the acceleration sensor on the artificial board, which ensures the bonding strength of the acceleration sensor, thereby ensuring the accuracy of the detection result, and at the same time reduces the labor intensity of the staff and improves work efficiency.
