The present invention also provides a method for detecting hidden cracks in furniture board processing, comprising the following steps:

Step 1: Place the plate to be tested in the inspection box, start the drive motor, so that the drive block on the output end drives the drive shaft to rotate, so that the two drive pulleys rotate;

Step 2: The driven pulleys are driven to rotate by two transmission belts, so that the driven shaft rotates, and the inspection box moves with the movement of the transmission belts. A plurality of inspection boxes are arranged on the transmission belts, so that the plates can be inspected in batches;

Step 3: The control box drives the first telescopic rod and the second telescopic rod to move the movable shaft to the center of the dark crack, and starts the stop motor so that its output end drives the stop cylinder to rotate;

Step 4: The stop cylinder is limitedly rotated in the stop slot through the stop block, so that the marking rod rotates on the plate with the stop cylinder as the center, marking the dark crack area of the plate.

Compared with the prior art, the present invention has the following beneficial effects:

(1) Through the follow-up lowering mechanism provided with an analysis module, when the analysis and stop transmission unit receives the data information transmitted by it, the control box drives the first telescopic rod and the second telescopic rod, thereby moving the matching rotating shaft to the center of the dark crack, and the output end of the starting stop motor drives the stop bevel gear to rotate and meshes with the matching bevel gear to rotate, so that it drives the stop cylinder to rotate through the matching rotating shaft, and then the stop cylinder is limited to rotate in the stop slot through the stop block, so that the marking rod rotates on the plate with the stop cylinder as the center, so that the dark crack area of the plate can be marked in real time, avoiding the confusion of qualified and unqualified plates when testing a large number of plates, so that the operator can repair the dark cracked plate in time, avoiding the recycling of the whole plate, thereby avoiding the waste of resources. At the same time, the analysis and stop transmission unit is arranged at the inspection box, avoiding the influence on the detection work of the acoustic wave detector, thereby improving the detection efficiency;

(2) When the inspection box moves, the inclined surface of the moving inclined plate contacts the inclined surface of the double inclined horizontal plate, and then the inspection rod moves toward each other in the inspection box, so that the inspection spring is in a buffer state, and the triggering rod enters the triggering sleeve, and then the static contact piece contacts the moving contact piece. The contact indication device of the two has limited the plate, avoiding the phenomenon that the plate moves during the detection, which causes the detection result to be inconsistent with the actual situation, thereby improving the detection accuracy; at the same time, the static contact piece and the moving contact piece contact each other, which will send a signal to the follow-up descending mechanism in the control box, indicating that the plate is about to move to the area to be detected. At the same time, the alarm unit provided in the control box can be used to remind the operator to pay attention, so as to avoid the operator's distraction during the detection and cause accidents;

(3) When the stop cylinder rotates, it drives the stop gear to rotate, so that the meshing guard gear rotates, and the guard threaded shaft rotates, so that the guard square plate connected by its thread moves within the guide rod through the guide square plate, so that the flexible pad provided on the linkage plate contacts the plate with hidden cracks. At the same time, the flexible pad has ductility, so that the flexible pad fits the plate. At the same time, a sensor is provided in the flexible pad. When the control box receives the signal from the sensor, the stop motor stops driving, so that the linkage plate and the flexible pad remain in the current position. When the inspection box moves to the head and is ready to move to the other side of the transmission belt, the inspection box stops driving. The square box flips, so that the plate also flips and prepares to fall. Since the speed of the plate falling is accelerated during flipping, the directional spring on the directional rod is in a buffering state. The buffering force brought by it offsets it, reducing the speed of the plate falling, thereby avoiding secondary damage to the plate that has been cracked, reducing the waste of resources, and reducing the limitations of the device when in use; at the same time, when the detection square box flips with the transmission belt, it will not be affected by the supporting cross plate; when the sensor receives the signal that the plate leaves the detection square box, it makes a series of units on the stop transmission unit return to the initial position and wait for the next detection operation;

When the gear train is in motion, the driven gear is driven to rotate, so that the driven bevel gear rotates and meshes with the active bevel gear, so that the active gear on the active shaft rotates and meshes with the active rack, so that the active rack moves through the active slider on the linkage guide rail. The double inclined horizontal plate is driven to move by extending the differential rod, so that the two double inclined horizontal plates move toward each other and contact the moving differential inclined plate, and then the two double inclined horizontal plates are limited and moved in the testing square box through the inspection square rod. The inspection spring is in a buffering state, so that the two contacting plates move toward each other, so that the plate is clamped in the testing square box. At the same time, the buffer pad can reduce the impact force caused by the clamping of the contacting plates, so that the buffer pad is in a buffering state, so as to avoid further damage to the plate with hidden cracks. At the same time, the double inclined horizontal plate contacts the reduction wheel, so as to reduce the friction between the double inclined horizontal plate and the differential inclined plate, so as to avoid the plate shaking caused by too much resistance when the testing square box moves, thereby improving the accuracy of the detection result.

(5) The plate to be inspected is placed in the inspection box, and the driving motor is started so that the driving block on the output end drives the driving shaft to rotate, so that the two driving pulleys rotate, and the driven pulleys rotate through two transmission belts, so that the driven shaft rotates. At the same time, an L-shaped moving cross bar is installed on each of the two transmission belts, and the two L-shaped moving cross bars are connected to the inspection box together, so that the inspection box moves with the movement of the transmission belt. A number of inspection boxes are arranged on the transmission belt, so that the plates can be inspected in batches, which improves the efficiency of the inspection. At the same time, the clamping pre-connection unit, the positioning detection and stopping component, the meshing and engaging component, the follow-up lowering mechanism, the analysis and stopping transmission unit and the slow closing and protecting mechanism are provided to assist the movement of the force transmission mechanism, so as to complete the inspection, avoid the traditional manual inspection, improve the accuracy of the inspection result, and reduce the workload of the staff, thereby reducing the limitations of the device when in use;

(6) When the signal is sent to the follow-up lowering mechanism, the telescopic cylinder starts working, and then its output end pushes the lowering cross plate to move, so that it moves within the positioning base through the positioning rod provided on the positioning block. When it moves to a certain extent, the active magnetic sheet provided on the auxiliary square plate will contact the driven magnetic sheet, so that the acoustic wave detector is energized, and the moving plate can be detected. By detecting the dark cracks on the plate through ultrasonic waves, energy loss is reduced and waste of resources is avoided. At the same time, when the detection module in the control box detects that the acoustic wave detector starts working, it sends a signal to the stop transmission unit, so that the stop motor, the first telescopic rod and the second telescopic rod provided therein are in a standby state, and can be driven accordingly at any time through the motion analysis module in the control box; and the motion analysis module can analyze the data transmitted by the acoustic wave detector. When there are no dark cracks or cracks in the plate, the follow-up lowering mechanism and the like are restored. The device moves to the next position and waits for the next inspection; when cracks are detected in the plate, the analysis module is used to compare and analyze the plate data map pre-stored in the control box, so as to analyze and determine the specific location of the crack, and mark it through the analysis and transmission unit, so as to avoid the operator being unable to mark or remember the specific area of cracks or dark cracks on the plate in time when inspecting a large number of plates, resulting in the inability to repair these dark cracked plates, which makes the qualified and unqualified plates confused, thereby avoiding the waste of resources and reducing the limitations of the device when in use; the above can be set according to the scenario used. When encountering a small-scale inspection, the distance between the two inspection boxes can be adjusted, which can reduce energy consumption and improve the accuracy of inspection to a certain extent. When encountering a large-scale inspection, the acoustic wave detector on the follow-up lowering mechanism can always work at the inspection height, which improves the efficiency of inspection;

(7) When the active gear rotates and drives the active rack to move, when it moves to a certain distance, it will mesh with the gear teeth. When it is meshed by the active gear, the gear teeth move back and forth in the meshing round rod through the locking plate. At the same time, the driven cross bar on the active rack contacts the active cross bar, so that the active rack cannot continue to move. The meshing spring is constantly in a buffering and resetting state, so that the active gear will not be stuck in the current position and can continue to rotate. At the same time, the force applied to the double inclined cross plate will always exist, avoiding the phenomenon that the positioning detection and stopping components bring uninterrupted pressure to the double inclined cross plate during long-term detection work, causing it to move, so that the positioning detection and stopping components can ensure the effect of fixing the plate.
