When the movable carrier frame 300 moves, the pressure plate 250 will be squeezed, and the multi-section hydraulic telescopic rod 240 will be squeezed by the pressure plate 250, so that the multi-section hydraulic telescopic rod 240 continues to shrink. At this time, the liquid in the two multi-section hydraulic telescopic rods 240 will be respectively injected into the two U-shaped hydraulic pipes 260, so that the liquid pressure in the two U-shaped hydraulic pipes 260 becomes larger, thereby causing the two hydraulic push rods 270 to extend synchronously. The hydraulic push rods 270 in the two groups of the linkage components are respectively fixed to the first C-shaped frame 410 and the second C-shaped frame 420, and the first C-shaped frame 410 and the second C-shaped frame 420 are respectively pushed synchronously by the two hydraulic push rods 270 to move in the opposite direction of the movable carrier frame 300.The movement of the detection component 400 is controlled by setting a linkage component, and the detection component 400 is pushed to move in the opposite direction during the movement of the movable carrier 300. Such a design can reduce the overall footprint of the equipment and reduce production costs. The movable carrier 300 is slidably connected in the first slide groove 210 inside the rectangular frame 200, and a plate entry groove 310 is provided in the movable carrier 300. A second through groove 330 connected to the plate entry groove 310 is provided in the movable carrier 300, and a second positioning slider 320 slidably connected to the second slide groove 220 is fixed on the outer side of the movable carrier 300. The linkage component includes a multi-section hydraulic telescopic rod 240 fixed inside the rectangular frame 200, one end of the multi-section hydraulic telescopic rod 240 is fixed with a pressing plate 250, and the other end of the multi-section hydraulic telescopic rod 240 is fixed and connected with a U-shaped The hydraulic pipeline 260, the internal piston of one end of the U-shaped hydraulic pipeline 260 away from the multi-section hydraulic telescopic rod 240 is slidably connected to the hydraulic push rod 270. When the movable carrier frame 300 moves, the pressure plate 250 will be squeezed, and the multi-section hydraulic telescopic rod 240 will be squeezed by the pressure plate 250, so that the multi-section hydraulic telescopic rod 240 continues to shrink. At this time, the liquid in the two multi-section hydraulic telescopic rods 240 will be respectively injected into the two U-shaped hydraulic pipelines 260, so that the liquid pressure in the two U-shaped hydraulic pipelines 260 becomes larger, thereby making the two hydraulic push rods 270 extend synchronously. The hydraulic push rods 270 in the two groups of the linkage components are respectively fixed to the first C-shaped frame 410 and the second C-shaped frame 420, and the first C-shaped frame 410 and the second C-shaped frame 420 are synchronously pushed to move in the opposite direction of the movable carrier frame 300 by the two hydraulic push rods 270. By setting a linkage component to control the movement of the detection component 400, the detection component 400 is pushed to move in the opposite direction during the movement of the movable carrier frame 300. Such a design can reduce the overall footprint of the equipment and reduce production costs. The movable carrier frame 300 is internally equipped with a stabilizing component, which includes a multi-way air pressure pipe 340 fixed in the movable carrier frame 300, and the four ports of the multi-way air pressure pipe 340 are all piston-slidingly connected with a clamping rod 360, and the other two ports of the multi-way air pressure pipe 340 are fixed and connected with an air storage bag body 350, and the positions of the two air storage bags 350 correspond to the positions of the two pressure plates 250.By setting a stabilizing component, the particle board that is slidably inserted into the movable carrier 300 can be clamped and positioned, ensuring that the particle board will not be displaced during the detection process, thereby ensuring the accuracy of the detection result. The robot takes the particle board inserted into the board entry slot 310 in the movable carrier 300, and the robot drives the particle board to move in the movable carrier 300 until it fits with the inner wall of the movable carrier 300 and pushes the movable carrier 300 to move. Subsequently, during the movement of the movable carrier 300, the air storage bag body 350 will first contact the pressure plate 250, so that the air storage bag body 350 is squeezed, and the gas in the two air storage bag bodies 350 enters the interior of the multi-pass air pressure pipe 340, and under the action of the gas pressure, the four clamping rods 360 will be pushed to move at the same time, and the four clamping rods 360 will be used to squeeze the surroundings of the particle board to form an extrusion positioning effect.

[0042] The outer side of the rectangular frame 200 is slidably sleeved with a detection component 400;

[0043] The detection assembly 400 includes a first C-shaped frame 410 and a second C-shaped frame 420. The first positioning sliders 450 are symmetrically fixed on the inner walls of the first C-shaped frame 410 and the second C-shaped frame 420. The first C-shaped frame 410 and the second C-shaped frame 420 are slidably connected to the first through groove 230 on the rectangular frame 200 through the first positioning sliders 450. Two C-shaped plates 440 are symmetrically fixed between the first C-shaped frame 410 and the second C-shaped frame 420. The middle parts of the two C-shaped plates 440 are rotatably connected with a rotating block 460. The two rotating blocks 460 are fixed with an eccentric connecting block 470 on the opposite sides. Each of the eccentric connecting blocks 470 is fixed with a strip mounting plate 4 120, a plurality of laser distance measuring sensors 4130 for detection are fixed on each of the bar-shaped mounting plates 4120, a transmission assembly is arranged on the outer sides of the two C-shaped plates 440, and the transmission assembly includes two first sprockets 480 fixedly connected to the outer sides of the rotating block 460, two rotating rods 4140 are symmetrically passed through and rotatably connected in the second C-shaped frame 420, and a second sprocket 4150 and a gear 4160 are fixed on both sides of each rotating rod 4140, and the two second sprockets 4150 are connected to the two first sprockets 480 through two chains 490, and the two gears 4160 are respectively meshed with the two latching tooth groups 280, and the second C A display 430 for displaying the detection results of the laser ranging sensor 4130 is fixed on the outside of the C-shaped frame 420, and a limiting block 4110 is fixed on one side of the two strip-shaped mounting plates 4120 close to the two C-shaped plates 440. A circular groove 4100 is opened on one side of the two C-shaped plates 440 close to the two strip-shaped mounting plates 4120, and the limiting block 4110 is slidably connected inside the circular groove 4100. The limiting block 4110 is adapted to the eccentric position of the eccentric connecting block 470 in the initial state. During the movement of the first C-shaped frame 410 and the second C-shaped frame 420, the two gears 4160 in the second C-shaped frame 420 are in the two gear groups 280. Under the action, the two gears 4160 rotate synchronously, and the two gears 4160 synchronously drive the two second sprockets 4150 to rotate through the two rotating rods 4140. The two second sprockets 4150 synchronously drive the two first sprockets 480 to rotate under the action of the two chains 490. Subsequently, the two first sprockets 480 will synchronously drive the two rotating blocks 460 to rotate. Since the two rotating blocks 460 are connected to the two strip mounting plates 4120 through the eccentric connecting block 470, when the two rotating blocks 460 rotate synchronously, the two strip mounting plates 4120 will be in an eccentric rotation state with the center of the rotating block 460, thereby causing each laser ranging sensor 4130 to be in an eccentric rotation state.

[0044] The warping degree of the particle board is detected by setting up a detection component 400. During the detection process, the laser distance sensor 4130 can perform a small range of circular motion during the longitudinal movement detection by cooperating with the linkage component, so that the detection range of each laser distance sensor 4130 is covered, thereby reducing the generation of detection blind spots.

[0045] When the above equipment is used, in the production process of particleboard, the finished particleboard passes through Figure 2 The conveyor belt in the production line shown in the figure is used for transmission, and the robot takes the particleboard and inserts it into the board feeding slot 310 in the movable plate carrier 300. As the robot drives the particleboard to move in the movable plate carrier 300, it fits with the inner wall of the movable plate carrier 300 and pushes the movable plate carrier 300 to move. Subsequently, during the movement of the movable plate carrier 300, the air storage bag body 350 will first contact the pressing plate 250, so that the air storage bag body 350 is squeezed, and the gas in the two air storage bags 350 enters the interior of the multi-pass air pressure pipe 340. Under the action of the gas pressure, the four pressing rods 360 will be pushed to move at the same time, and the four pressing rods 360 will be used to squeeze the surroundings of the particleboard to form an extrusion positioning effect.

[0046] As the manipulator continues to push, the movable plate carrier 300 will continue to squeeze the pressing plate 250, and squeeze the multi-section hydraulic telescopic rod 240 through the pressing plate 250, so that the multi-section hydraulic telescopic rod 240 continues to shrink. At this time, the liquid in the two multi-section hydraulic telescopic rods 240 will be respectively injected into the inside of the two U-shaped hydraulic pipes 260, so that the liquid pressure in the two U-shaped hydraulic pipes 260 increases, and then the two hydraulic push rods 270 are synchronously extended, and the first C-shaped frame 410 and the second C-shaped frame 420 are synchronously pushed by the two hydraulic push rods 270 to move in the opposite direction of the movable plate carrier 300. At this time, the laser distance sensor 4130 starts to detect and displays the detection data through the display 430;

[0047] At the same time, during the movement of the first C-shaped frame 410 and the second C-shaped frame 420, the two gears 4160 in the second C-shaped frame 420 rotate synchronously under the action of the two latching tooth groups 280, and the two gears 4160 synchronously drive the two second sprocket wheels 4150 to rotate through the two rotating rods 4140, and the two second sprocket wheels 4150 synchronously drive the two first sprocket wheels 480 to rotate under the action of the two chains 490, and then the two first sprocket wheels 480 synchronously drive the two rotating blocks 460 to rotate. 0 are connected to the two strip-shaped mounting plates 4120 through the eccentric connecting block 470, so when the two rotating blocks 460 rotate synchronously, the two strip-shaped mounting plates 4120 will be in an eccentric rotating state with the center of the rotating block 460, and then each laser ranging sensor 4130 will be in an eccentric rotating state, so that the laser ranging sensor 4130 can perform a small range of eccentric rotation movement during longitudinal movement detection, so that the detection range of each laser ranging sensor 4130 is covered, thereby reducing the generation of detection blind areas, thereby improving the comprehensiveness of detection;

[0048] It is worth noting that the present application has a circular groove 4100 on the C-shaped plate 440, and at the same time, a limit block 4110 is fixed on the strip-shaped mounting plate 4120, which can limit the movement trajectory of the strip-shaped mounting plate 4120 and provide a good supporting effect;

[0049] Furthermore, the second slide groove 220 opened on the side of the rectangular frame 200 can cooperate with the second positioning slider 320 to position the movement trajectory of the movable carrier frame 300. At the same time, the multiple first slide grooves 210 set on the rectangular frame 200 can limit the movement trajectory of the first C-shaped frame 410 and the second C-shaped frame 420 by cooperating with the first positioning slider 450 on the first C-shaped frame 410 and the second C-shaped frame 420.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
