Description

Technical Field

[0001] The present invention relates to the technical field of level detection, and specifically to a detection device for wood board installation with an active level correction function. Background Art

[0002] In modern engineering construction, leveling and installing wood boards are often the preliminary steps of construction. The mainstream leveling method for existing wood board installation is still for operators to use a spirit level for operation. The operation efficiency is relatively low, and it is easy to have errors in manual judgment, and the levelness is not accurate enough. On this basis, operators assist in using a laser level to correct the installation of the wood board. Compared with using a spirit level, operators can measure each position of the wood board through an entire horizontal plane to further improve the leveling effect. However, the laser level still needs to be manually leveled by the operator before use. During the construction process, the operator also needs to move the laser level as they move. Each time the laser level moves to a new position, the levelness needs to be recalibrated, which is cumbersome to use, has a low degree of automation, and low efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a detection device for wood board installation with an active level correction function to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A detection device for wood board installation with an active level correction function, including a main board, an upper chassis, and a lower chassis. The upper chassis and the lower chassis are respectively arranged at the upper and lower ends of the main board. A balance detection mechanism is arranged inside the upper chassis, and a variable angle mechanism is installed in the lower chassis. Several automatic suction cups are installed on the variable angle mechanism, and the automatic suction cups position the wood board. Balance adjustment mechanisms are installed at the four corners of the main board, and both the balance adjustment mechanism and the balance detection mechanism are electrically connected to the control system.

[0005] Further, the balance detection mechanism includes a frame-shaped frame, a counterweight, and a turntable. The frame-shaped frame is rotatably mounted on the upper chassis, and the counterweight is rotatably mounted in the frame-shaped frame. The rotation direction of the counterweight is perpendicular to the rotation direction of the frame-shaped frame. The turntable is rotatably mounted on the counterweight, and a first motor and an inertial wheel are provided on the turntable. The inertial wheel is coaxially connected to the motor shaft of the first motor. Before the detection device is started, regardless of whether the main board is horizontal or not, the degree of freedom of the counterweight is released by using the frame-shaped frame, so that the counterweight can maintain a horizontal state under the action of gravity. The first motor is powered on to drive the inertial wheel to rotate at a high speed. Part of the force generated by the inertial wheel is in the same direction as the axis of rotation, and the other part causes the turntable to slowly rotate around the reflective column on the counterweight. During the subsequent movement of the detection device, the change of the main board will not affect the horizontal state of the counterweight, providing a basis for continuous horizontal measurement.

[0006] Further, the balance detection mechanism further includes a reflective column, a plurality of receiving plates, and a laser emitter. The reflective column is connected to the bottom of the turntable, passes through the counterweight, and a 45° inclined surface is provided at the bottom of the reflective column. A reflector is provided on the inclined surface. The laser emitter is provided on the main board and is located directly below the reflective column. The plurality of receiving plates are arranged in a circular pattern and evenly distributed at the bottom of the counterweight. The laser emitter on the main board emits light, and the light is reflected by the reflector and then reaches the receiving plate. Also, due to the rotation of the turntable causing the reflective column to rotate, the reflected light leaves a circular trajectory on the receiving plate. The inclination angle of the light reflector is 45°, and when the counterweight is in a horizontal state, the incident angle and the reflection angle of the light emitted by the laser emitter are always the same. If the circular light trajectory received by the receiving plate is on the same horizontal plane, then the main board is also in a horizontal state and does not need to be adjusted by the balance adjustment mechanism. If the main board is not in a horizontal state, the circular light trajectory received by the receiving plate is not on the same horizontal plane. The receiving plate determines which corner the lower side of the main board is in through the light trajectory, and the balance adjustment mechanism is controlled by the control system to adjust the main board to a horizontal state.

[0007] Further, each balance adjustment mechanism includes a fine-tuning motor, a lead screw, a sliding cylinder, a support leg, and a sphere. The fine-tuning motor is installed above the main board, the lead screw is connected to the motor shaft of the fine-tuning motor, the sliding cylinder is arranged below the main board, the lead screw passes through the main board and extends into the sliding cylinder, the support leg is slidably arranged on the sliding cylinder, one side of the support leg extends into the sliding cylinder, the support leg is threadedly connected to the lead screw, and the sphere is rotatably installed at the bottom of the support leg. The fine-tuning motor is powered on to drive the lead screw to rotate, and the lead screw drives the support leg to slide up and down in the sliding cylinder through screw transmission to adjust the height of the support leg and achieve the horizontal adjustment of the main board.

[0008] Further, two drive units are arranged inside the outrigger. The two drive units are vertically distributed in space. Each drive unit includes a small motor, a toothed comb shaft, a sleeve, and a number of rubber rings. The toothed comb shaft is connected to the motor shaft of the small motor. The sleeve is installed outside the toothed comb shaft. A number of fine slits are evenly distributed in a ring shape on the toothed comb shaft. The number of rubber rings are sleeved on the sleeve, and the number of rubber rings are respectively embedded in the number of fine slits. The rubber rings are in contact with the sphere. The two drive units drive the sphere to roll forward and roll sideways to control the movement of the entire detection device. The small motor drives the toothed comb shaft and the sleeve to rotate. The rubber rings on the sleeve drive the sphere to rotate through friction. When the sphere rolls forward, the rubber rings on the other drive unit slide on the sleeve and do not interfere with the forward rolling of the sphere. When the sphere rolls sideways, the rubber rings driving the sphere to roll forward slide on the sleeve. By driving the sphere to roll through the two drive units, the entire device can be driven to move in two directions. The transmission is carried out through the rubber rings sleeved on the sleeve, and at the same time, the rolling of the sphere in the other direction is avoided from being interfered.

[0009] Further, the angle-changing mechanism includes a second motor, a side bevel gear, an upper bevel gear, and a lower bevel gear. The second motor is installed outside the lower machine case. The side bevel gear is rotatably installed inside the lower machine case. The motor shaft of the second motor penetrates the lower machine case and is connected to the side bevel gear. The upper bevel gear and the lower bevel gear are symmetrically arranged up and down. The side bevel gear meshes with the upper bevel gear and the lower bevel gear. An inner core shaft is provided at the bottom of the upper bevel gear. An outer sleeve shaft is provided at the bottom of the lower bevel gear. The outer sleeve shaft penetrates the lower machine case. The inner core shaft penetrates the lower bevel gear and the outer sleeve shaft. A pair of upper cantilevers are symmetrically installed on the outer sleeve shaft. A pair of lower cantilevers are symmetrically installed on the inner core shaft. Four automatic suction cups are respectively arranged at the ends of a pair of upper cantilevers and a pair of lower cantilevers. The control system controls the second motor to be energized to drive the side bevel gear to rotate. The side bevel gear drives the upper bevel gear and the lower bevel gear to rotate. The rotation directions of the upper bevel gear and the lower bevel gear are opposite. The upper bevel gear drives two automatic suction cups to move through the inner core shaft and the lower cantilevers. The lower bevel gear drives two automatic suction cups to move through the outer sleeve shaft and the upper cantilevers to adjust the positions of the four automatic suction cups to adapt to sucking wooden boards with different contour sizes.

[0010] Further, each automatic suction cup includes an electric push rod, a sealed cylinder body, and a sliding suction cup. The electric push rod is connected to the upper cantilever or the lower cantilever. The sealed cylinder body is arranged on the piston rod of the electric push rod. The sliding suction cup is slidably installed in the sealed cylinder body. The sliding suction cup is vertically through. A spring is arranged between the sliding suction cup and the sealed cylinder body. The four electric push rods simultaneously push the sealed cylinder body downward. The sealed cylinder body drives the sliding suction cup to move downward until it contacts the wooden board. As the continuous downward pressure is applied, the spring is compressed, and the air in the sealed cylinder body is squeezed out through the bottom of the sliding suction cup.

[0011] Furthermore, a free shift block is rotatably mounted on the sliding suction cup, and the bottom of the free shift block is against the sliding suction cup. A one-way gear pulley is rotatably mounted on the bottom position of the sealed cylinder body, and circular holes are evenly distributed on the one-way gear pulley in a circular shape. A valve inner hole is opened inside the sealed cylinder body, and one end of the valve inner hole is connected to the atmosphere, and the other end of the valve inner hole is connected to the interior of the sealed cylinder body.

[0012] Furthermore, the one-way gear pulley rotates in one direction.

[0013] Furthermore, the one-way gear pulley blocks the inner hole of the valve, and the free pull block pulls the one-way gear pulley to rotate a certain angle, so that the one-way gear pulley blocks the inner hole of the valve. When the electric push rod moves upward, the spring stretches the sealing cylinder body and the sliding suction cup to open, so that negative pressure is formed inside the sealing cylinder body, and the sliding suction cup firmly sucks the wooden board and lifts the wooden board. When the sliding suction cup moves downward relative to the sealing cylinder body, the free pull block deflects upward and passes the one-way gear pulley, and will not drive the one-way gear pulley to rotate in the opposite direction. When the wooden board needs to be put down, the electric push rod pushes the sealing cylinder body downward again at the same time, and the wooden board contacts the ground. The operator installs the wooden board. As the squeezing continues, the sliding suction cup moves upward, the spring is compressed again, and the free pull block pulls the one-way gear pulley to rotate a certain angle again, and the circular hole on the one-way gear pulley is connected with the inner hole of the valve, the inside of the sealing cylinder body is connected with the external atmosphere, and the sliding suction cup loses its adsorption force on the wooden board.

[0014] The wooden board is squeezed by the automatic suction cup, first squeezed once to adsorb, and then squeezed again to release, so as to achieve horizontal installation of the wooden board.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The inertia wheel rotates at high speed to keep the counterweight in a horizontal state. During the subsequent movement of the detection device, changes in the mainboard will not affect the horizontal state of the counterweight, providing a basis for continuous horizontal measurement. The laser transmitter emits light with the same incident angle and reflection angle, leaving a circular track on the receiving board. The receiving board determines which corner the lower side of the mainboard is in through the track of the light, and controls the balance adjustment mechanism to adjust the mainboard to a horizontal state through the control system. The ball is driven to roll by two sets of driving units, which can drive the entire device to move in two directions. The transmission is carried out through a rubber ring mounted on the sleeve, while avoiding interference with the rolling of the ball in the other direction. The wooden board is squeezed by an automatic suction cup, which is first squeezed once for adsorption and then squeezed again for release, so as to achieve horizontal installation of the wooden board.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment: As Figures 1 - 10 shown, the present invention provides a technical solution, a detection device for wooden board installation with an active leveling correction function, including a main board 1, an upper chassis 2 and a lower chassis 3. The upper chassis 2 and the lower chassis 3 are respectively arranged at the upper and lower ends of the main board 1. A balance detection mechanism is arranged in the upper chassis 2, and a variable angle mechanism is installed in the lower chassis 3. Several automatic suction cups 35 are installed on the variable angle mechanism. The automatic suction cups 35 position the wooden board. Balance adjustment mechanisms are installed at the four corners of the main board 1. Both the balance adjustment mechanism and the balance detection mechanism are electrically connected to the control system.

[0030] The balance detection mechanism includes a frame-shaped frame 13, a counterweight 14 and a turntable 15. The frame-shaped frame 13 is rotatably installed on the upper chassis 2. The counterweight 14 is rotatably installed in the frame-shaped frame 13. The rotation direction of the counterweight 14 is perpendicular to the rotation direction of the frame-shaped frame 13. The turntable 15 is rotatably installed on the counterweight 14. A first motor 17 and an inertia wheel 18 are arranged on the turntable 15. The inertia wheel 18 is coaxially connected to the motor shaft of the first motor 17. The balance detection mechanism further includes a reflecting column 16, several receiving plates 19 and a laser emitter 20. The reflecting column 16 is connected to the bottom of the turntable 15. The reflecting column 16 penetrates through the counterweight 14. A 45° inclined surface is provided at the bottom of the reflecting column 16. A reflecting mirror is arranged on the inclined surface. The laser emitter 20 is arranged on the main board 1. The laser emitter 20 is located directly below the reflecting column 16. Several receiving plates 19 are arranged in a circular and evenly distributed manner at the bottom of the counterweight 14.

[0031] Before the detection device is started, regardless of whether the main board 1 is horizontal or not, the freedom degree of the counterweight 14 is released by using the frame 13, so that the counterweight 14 can maintain a horizontal state under the action of gravity. The first motor 17 is energized to drive the inertial wheel 18 to rotate at a high speed. A part of the force generated by the inertial wheel 18 is in the same direction as the axis of the rotating shaft, and the other part causes the turntable 15 to slowly rotate around the reflecting column 16 on the counterweight 14. During the subsequent movement of the detection device, the change of the main board 1 will not affect the horizontal state of the counterweight 14, providing a basis for continuous horizontal measurement. The laser emitter 20 on the main board 1 emits light, and after the light hits the reflector, it is reflected onto the receiving board 19. Also, because the turntable 15 causes the reflecting column 16 to rotate, the reflected light leaves a circular trajectory on the receiving board 19. The inclination angle of the light reflector is 45°, and the counterweight 14 is in a horizontal state. The incident angle and the reflection angle of the light emitted by the laser emitter 20 are always the same. If the circular light trajectory received by the receiving board 19 is on the same horizontal plane, then the main board 1 is also in a horizontal state and does not need to be adjusted by the balance adjustment mechanism. If the main board 1 is not in a horizontal state and the circular light trajectory received by the receiving board 19 is not on the same horizontal plane, the receiving board 19 judges which corner the lower side of the main board 1 is in through the light trajectory, and controls the balance adjustment mechanism to adjust the main board 1 to a horizontal state through the control system.

[0032] Each of the balance adjustment mechanisms includes a fine-tuning motor 4, a lead screw 5, a sliding cylinder 6, a support leg 7 and a sphere 8. The fine-tuning motor 4 is installed above the main board 1. The lead screw 5 is connected to the motor shaft of the fine-tuning motor 4. The sliding cylinder 6 is arranged below the main board 1. The lead screw 5 passes through the main board 1 and extends into the sliding cylinder 6. The support leg 7 is slidably arranged on the sliding cylinder 6. One side of the support leg 7 extends into the sliding cylinder 6. The support leg 7 is threadedly connected to the lead screw 5. The sphere 8 is rotatably installed at the bottom of the support leg 7. Two driving groups are arranged inside the support leg 7. The two driving groups are vertically distributed in space. Each driving group includes a small motor 9, a toothed comb shaft 10, a sleeve 11 and a plurality of rubber rings 12. The toothed comb shaft 10 is connected to the motor shaft of the small motor 9. The sleeve 11 is installed outside the toothed comb shaft 10. A plurality of fine slits are annularly and evenly arranged on the toothed comb shaft 10. The plurality of rubber rings 12 are sleeved on the sleeve 11. The plurality of rubber rings 12 are respectively embedded in the plurality of fine slits. The rubber rings 12 are in contact with the sphere 8.

[0033] The fine-tuning motor 4 is energized to drive the lead screw 5 to rotate. The lead screw 5 drives the support leg 7 to slide up and down in the sliding cylinder 6 through screw transmission, adjusts the height of the support leg 7, and realizes the horizontal adjustment of the main board 1. Two drive units drive the sphere 8 to roll forward and roll sideways, controlling the movement of the entire detection device. The small motor 9 drives the tooth comb shaft 10 and the sleeve 11 to rotate. The rubber ring 12 on the sleeve 11 drives the sphere 8 to rotate through friction. When the sphere 8 rolls forward, the rubber ring 12 on the other drive unit slides on the sleeve 11 and does not interfere with the forward roll of the sphere 8. When the sphere 8 rolls sideways, the rubber ring 12 that drives the sphere 8 to roll forward slides on the sleeve 11. By driving the sphere 8 to roll through two drive units, the entire device can be driven to move in two directions. The transmission is carried out through the rubber ring 12 sleeved on the sleeve 11, and at the same time, the rolling of the sphere 8 in the other direction is avoided from being interfered.

[0034] The angle-changing mechanism includes a second motor 21, a side bevel gear 22, an upper bevel gear 23, and a lower bevel gear 24. The second motor 21 is installed on the outer side of the lower chassis 3. The side bevel gear 22 is rotatably installed inside the lower chassis 3. The motor shaft of the second motor 21 penetrates through the lower chassis 3 and is connected to the side bevel gear 22. The upper bevel gear 23 and the lower bevel gear 24 are symmetrically arranged up and down. The side bevel gear 22 meshes with the upper bevel gear 23 and the lower bevel gear 24. The bottom of the upper bevel gear 23 is provided with an inner core shaft 26, and the bottom of the lower bevel gear 24 is provided with an outer sleeve shaft 25. The outer sleeve shaft 25 penetrates through the lower chassis 3. The inner core shaft 26 penetrates through the lower bevel gear 24 and is connected to the outer sleeve shaft 25. A pair of upper cantilever arms 27 are symmetrically installed on the outer sleeve shaft 25, and a pair of lower cantilever arms 28 are symmetrically installed on the inner core shaft 26. Four automatic suction cups 35 are respectively arranged at the ends of a pair of upper cantilever arms 27 and a pair of lower cantilever arms 28. The control system controls the second motor 21 to be energized to drive the side bevel gear 22 to rotate. The side bevel gear 22 drives the upper bevel gear 23 and the lower bevel gear 24 to rotate. The rotation directions of the upper bevel gear 23 and the lower bevel gear 24 are opposite. The upper bevel gear 23 drives two automatic suction cups 35 to move through the inner core shaft 26 and the lower cantilever arms 28. The lower bevel gear 24 drives two automatic suction cups 35 to move through the outer sleeve shaft 25 and the upper cantilever arms 27, so as to adjust the positions of the four automatic suction cups 35 to adapt to the suction of wooden boards with different contour sizes.

[0035] Each of the automatic suction cups 35 includes an electric push rod 29, a sealing cylinder 30 and a sliding suction cup 31. The electric push rod 29 is connected to the upper cantilever 27 or the lower cantilever 28. The sealing cylinder 30 is arranged on the piston rod of the electric push rod 29. The sliding suction cup 31 is slidably installed in the sealing cylinder 30. The sliding suction cup 31 passes through from top to bottom. A spring (not shown in the figure) is arranged between the sliding suction cup 31 and the sealing cylinder 30. A free shifting block 32 is rotatably installed on the sliding suction cup 31. The bottom of the free shifting block 32 abuts against the sliding suction cup 31. A one-way gear is rotatably installed at the bottom position of the sealing cylinder 30. The one-way gear puller 33 is provided with circular holes evenly distributed in a circular shape, and the interior of the sealed cylinder body 30 is provided with a valve inner hole 34, one end of the valve inner hole 34 is connected to the atmosphere, and the other end of the valve inner hole 34 is connected to the interior of the sealed cylinder body 30. The one-way gear puller 33 rotates in one direction, and the one-way gear puller 33 blocks the valve inner hole 34. The four electric push rods 29 push the sealed cylinder body 30 downward at the same time, and the sealed cylinder body 30 drives the sliding suction cup 31 to move downward until it contacts the wooden board. As the downward pressure continues, the spring is compressed, and the air in the sealed cylinder body 30 is squeezed out through the bottom of the sliding suction cup 31.

[0036] The free shift block 32 shifts the one-way gear dial 33 to rotate a certain angle, and the one-way gear dial 33 blocks the valve inner hole 34. When the electric push rod 29 moves upward, the spring opens the sealing cylinder 30 and the sliding suction cup 31, so that negative pressure is formed inside the sealing cylinder 30. The sliding suction cup 31 firmly sucks the wooden board and lifts it up. When the sliding suction cup 31 moves downward relative to the sealing cylinder 30, the free shift block 32 deflects upward and passes over the one-way gear dial 33, and will not drive the one-way gear dial 33 to rotate in the opposite direction. When the wooden board needs to be put down, the electric push rod 29 is moved again. At the same time, the sealing cylinder 30 is pushed downward, the wooden board touches the ground, and the operator installs the wooden board. With continued squeezing, the sliding suction cup 31 moves up, the spring is compressed again, and the free dial block 32 again drives the one-way gear dial 33 to rotate a certain angle. The circular hole on the one-way gear dial 33 is connected with the valve inner hole 34, and the inside of the sealing cylinder 30 is connected with the external atmosphere. The sliding suction cup 31 loses its adsorption force on the wooden board, and the wooden board is squeezed by the automatic suction cup 35, first squeezed once for adsorption, and then squeezed again for release, to achieve horizontal installation of the wooden board.

[0037] Working principle of the present invention: Before the detection device is started, regardless of whether the main board 1 is horizontal, the degree of freedom of the counterweight 14 is released by using the frame 13, so that the counterweight 14 can maintain a horizontal state under the action of gravity. The first motor 17 is energized to drive the inertial wheel 18 to rotate at a high speed. A part of the force generated by the inertial wheel 18 is in the same direction as the axis of rotation, and the other part causes the turntable 15 to slowly rotate around the reflecting column 16 on the counterweight 14. During the subsequent movement of the detection device, the change of the main board 1 will not affect the horizontal state of the counterweight 14, providing a basis for continuous horizontal measurement. The laser emitter 20 on the main board 1 emits light, and the light is reflected by the reflector and then reaches the receiving plate 19. Also, because the turntable 15 causes the reflecting column 16 to rotate, the reflected light leaves a circular trajectory on the receiving plate 19. The inclination angle of the light reflector is 45°, and the counterweight 14 is in a horizontal state. The incident angle and the reflection angle of the light emitted by the laser emitter 20 are always the same. If the circular light trajectory received by the receiving plate 19 is on the same horizontal plane, then the main board 1 is also in a horizontal state and does not need to be adjusted by the balance adjustment mechanism. If the main board 1 is not in a horizontal state, the circular light trajectory received by the receiving plate 19 is not on the same horizontal plane. The receiving plate 19 judges which corner the lower side of the main board 1 is in through the light trajectory, and controls the balance adjustment mechanism to adjust the main board 1 to a horizontal state through the control system.

[0038] The fine-tuning motor 4 is energized to drive the lead screw 5 to rotate. The lead screw 5 drives the support leg 7 to slide up and down in the sliding cylinder 6 through screw transmission to adjust the height of the support leg 7 and realize the horizontal adjustment of the main board 1. Two drive units drive the sphere 8 to roll forward and roll sideways to control the movement of the entire detection device. The small motor 9 drives the gear comb shaft 10 and the sleeve 11 to rotate. The rubber ring 12 on the sleeve 11 drives the sphere 8 to rotate through friction. When the sphere 8 rolls forward, the rubber ring 12 on the other drive unit slides on the sleeve 11 and does not interfere with the forward roll of the sphere 8. When the sphere 8 rolls sideways, the rubber ring 12 that drives the sphere 8 to roll forward slides on the sleeve 11. By driving the sphere 8 to roll through two drive units, the entire device can be driven to move in two directions. The transmission is carried out through the rubber ring 12 sleeved on the sleeve 11, and at the same time, the rolling of the sphere 8 in the other direction is avoided from being interfered.

[0039] The control system controls the second motor 21 to be energized to drive the side bevel gear 22 to rotate, and the side bevel gear 22 drives the upper bevel gear 23 and the lower bevel gear 24 to rotate. The upper bevel gear 23 and the lower bevel gear 24 have opposite directions. The upper bevel gear 23 drives the two automatic suction cups 35 to move through the inner core shaft 26 and the lower cantilever 28, and the lower bevel gear 24 drives the two automatic suction cups 35 to move through the outer sleeve shaft 25 and the upper cantilever 27 to adjust the positions of the four automatic suction cups 35 to adapt to the suction of wooden boards with different contour sizes. The four electric push rods 29 simultaneously push the sealing cylinder 30 downward, and the sealing cylinder 30 drives the sliding suction cup 31 to move downward until it contacts the wooden board. As the downward pressure continues, the spring is compressed, and the air in the sealing cylinder 30 is squeezed out through the bottom of the sliding suction cup 31.

[0040] The free shift block 32 shifts the one-way gear dial 33 to rotate a certain angle, and the one-way gear dial 33 blocks the valve inner hole 34. When the electric push rod 29 moves upward, the spring opens the sealing cylinder 30 and the sliding suction cup 31, so that negative pressure is formed inside the sealing cylinder 30. The sliding suction cup 31 firmly sucks the wooden board and lifts it up. When the sliding suction cup 31 moves downward relative to the sealing cylinder 30, the free shift block 32 deflects upward and passes over the one-way gear dial 33, and will not drive the one-way gear dial 33 to rotate in the opposite direction. When the wooden board needs to be put down, the electric push rod 29 is moved again. At the same time, the sealing cylinder 30 is pushed downward, the wooden board touches the ground, and the operator installs the wooden board. With continued squeezing, the sliding suction cup 31 moves up, the spring is compressed again, and the free dial block 32 again drives the one-way gear dial 33 to rotate a certain angle. The circular hole on the one-way gear dial 33 is connected with the valve inner hole 34, and the inside of the sealing cylinder 30 is connected with the external atmosphere. The sliding suction cup 31 loses its adsorption force on the wooden board, and the wooden board is squeezed by the automatic suction cup 35, first squeezed once for adsorption, and then squeezed again for release, to achieve horizontal installation of the wooden board.
