[0009] On the basis of the above technical scheme, the suction device includes a guide frame, a slider, a No. 4 connecting nozzle, a clamping nut, and a No. 3 connecting nozzle. The support frame includes guide frames fixed on the upper left, lower left, upper right, and lower right parts.

The virtual straight line where the projection point formed by the laser emitter in the front plane is located is in the same plane as the direction of the two adjacent claws.

[0012] Compared with the prior art, the present invention has the following advantages: when paving on the wall, the present invention uses the clamping claws to contact the edge of the paved board, and uses the thickness of the clamping claws to achieve a gap. After the paving position is determined to be accurate through an external line projection meter, the suction device is first controlled to stop working to release the adsorption effect of the suction cup on the board. Then, the rotation drive mechanism is controlled to rotate the clamping claws forward, thereby releasing the contact with the edge of the board. Then, the push-pull mechanism is controlled to move the clamping claws away from the middle of the support frame, and the board can be grasped and auxiliary positioning work can be carried out again. Since the clamping claws are in contact with the four edges of the board, the force is more uniform when disengaging, which is less likely to cause the board to move, reducing interference with the board positioning effect. By changing the initial meshing position of the rack and the gear ring, the angle between the claw head and the support frame in the initial state can be adjusted. Since the stroke of the rack remains basically unchanged, after the front handle is plugged into the front groove, the angle between the final position to which the claw head rotates backward and the support frame changes. Moreover, since the claw head rotates with the claw rod as the axis, when the claw head rotates to the final position, the front-to-back distance between its farthest rearward part and the rear end of the suction cup changes, thereby adapting to plates of different thicknesses, so that the final position of the clamping claw does not interfere with the laying of the plate, that is, the claw head will not contact the wall, causing the adhesive behind the plate to be unable to contact the wall. Before the suction cup is fitted with the surface of the plate, the rear end of the sponge pad is in contact with the surface of the plate, and then the button switch is pressed, and the mobile power supply is used to provide power to the fan to make the fan rotate, thereby extracting the air around the sponge pad through the No. 1 exhaust pipe, the air pressure hose, and the No. 2 exhaust pipe. During this period, the main handle, the upper extension rod and the lower extension rod are held to rotate the device so that the sponge pad forms a circular moving trajectory on the surface of the plate, and then the button switch is pressed again to cut off the power supply, and then the suction cup is fitted with the moving trajectory of the sponge pad. Due to the moving friction between the sponge pad and the plate, and the suction of air, dust particles can be well absorbed, thereby improving the adsorption and grasping effect of the suction cup and the plate.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-6 As shown, an auxiliary positioning device for exterior wall decorative panels for decoration, comprising a support frame 1, a main handle 2, a clamping jaw, a rotation drive mechanism, a push-pull mechanism, a suction cup 6, and a suction device, wherein the main handle 2 is fixed to the front end of the middle portion of the support frame 1, and a group of clamping jaws are respectively installed on the upper, lower, left and right parts of the support frame 1, and the clamping jaws are rotationally connected and axially slidably connected compared to the support frame 1, and the virtual rotation axes of the upper and lower clamping jaws of the support frame 1 are vertically arranged, and the virtual rotation axes of the left and right clamping jaws of the support frame 1 are horizontally arranged left and right, and the support frame 1 is equipped with a rotation driving mechanism and a push-pull mechanism, and the rotation driving mechanism is used to drive each group of clamping jaws to rotate about its virtual rotation axis, and the push-pull mechanism is used to drive each group of clamping jaws to slide axially along its virtual rotation axis, and a plurality of suction cups 6 with flush adsorption surfaces are also installed at the rear portion of the support frame 1, and a suction device is installed, and the suction device is connected to the suction cup 6 through an air path to realize suction of the air in the suction cup 6, and the rear end of the suction cup 6 is located at the rear side of the support frame 1.

[0022] When in use, first clean the surface of the rectangular plate 54, then make the suction cup 6 fit with the surface of the plate 54, then control the rotation drive mechanism to make the clamping claws rotate backward, then control the push-pull mechanism to pull each clamping claw toward the middle of the support frame 1, so that the clamping claws contact the four edges of the plate 54 to achieve clamping positioning, and the force is stable and uniform. Then control the suction device to work, and the air in the suction cup 6 can be extracted. The suction cup 6 is used to absorb and grab the plate 54, and the main handle 2 can be held to carry out the paving work. When paving on the wall, the clamping claws are used to contact the edges of the paved plate 54. , use the thickness of the clamping jaws to leave a gap, and after determining that the paving position is accurate through an external line projection meter, first control the suction device to stop working, release the adsorption effect of the suction cup 6 on the plate 54, and then control the rotation drive mechanism to make the clamping jaws rotate forward, thereby releasing the contact with the edge of the plate 54, and then control the push-pull mechanism to make the clamping jaws move away from the middle of the support frame 1, and then the plate 54 can be grasped and assisted in positioning again. Since the clamping jaws are in contact with the four edges of the plate 54, the force is more evenly distributed when disengaging, which is not easy to cause the movement of the plate 54, reducing the interference with the positioning effect of the plate 54.

[0023] The rotary drive mechanism includes an inner sleeve 10, an outer sleeve 11, a gear ring 12, a sliding frame 13, a rack 14, a front handle 15, a front groove 16, a light rod 17, and a No. 1 compression spring 18. The two clamping jaws are a group, and the two clamping jaws in the two groups of clamping jaws on the upper and lower parts of the support frame 1 are symmetrical to each other on the left and right, and the two clamping jaws in the two groups of clamping jaws on the left and right parts of the support frame 1 are symmetrical to each other up and down. The clamping jaws include a claw head 8 and a claw rod 9, and the claw head 8 is fixed at a right angle to the axial end of the claw rod 9. Each of the claw rods 9 is axially slidably connected to the inner sleeve 10, and each of the inner sleeves 10 is coaxially fastened with an outer sleeve 11, and is rotatably connected to the support frame 1 respectively. Each of the outer sleeves 11 is coaxially fixed with a gear ring 12, and the main handle 2 is slidably connected to the sliding frame 13 front and back. The sliding frame 13 is up, down, left and right. A group of racks 14 are fixed to each part, and the two racks 14 form a group. The two racks 14 in the two groups of racks 14 on the upper and lower parts of the support frame 1 are symmetrical with each other on the left and right, and the two racks 14 in the two groups of racks 14 on the left and right parts of the support frame 1 are symmetrical with each other up and down, and each rack 14 is respectively engaged with the gear ring 12, and a front handle 15 is fixed to the front end of the sliding frame 13, and a front groove 16 is opened at the front of the main handle 2, and the front of the front handle 15 can be matched and plugged into the front groove 16, and a plurality of light rods 17 and No. 1 compression springs 18 extending in the front and rear directions are fixed to the rear end of the sliding frame 13, and the light rods 17 are gap-insulated in the No. 1 compression spring 18 and are slidably connected to the support frame 1 back and forth. Under the elastic repulsive force of the No. 1 compression spring 18, the sliding frame 13 has a tendency to move forward compared with the support frame 1.

[0024] Furthermore, the main handle 2 is held by the palm part so that the suction cup 6 fits into the surface of the plate 54, and then the thumb presses the front handle 15 backward to insert it into the front groove 16, and the main handle 2 and the front handle 15 are held at the same time. When the front handle 15 moves backward, the sliding frame 13 can drive the rack 14 to move backward, so that the engagement of the rack 14 with the ring gear 12 makes the outer sleeve 11, the inner sleeve 10, the claw rod 9 and the claw head 8 rotate backward. When the clamping positioning of the plate 54 is released, it is only necessary to release the rear pressure and grip of the front handle 15, and the sliding frame 13 and the rack 14 can be moved forward under the elastic repulsive force of the No. 1 compression spring 18, so that the gear, outer sleeve 11, inner sleeve 10, claw rod 9 and claw head 8 are reversed and can be disengaged from the plate 54.

[0025] The rotary drive mechanism also includes a rotary support seat 19, a fastening bolt 20, and a fastening socket 21. The support frame 1 includes eight groups of rotary support seats 19 fixed at the upper, lower, left and right parts. Two adjacent and coaxially arranged rotary support seats 19 form a group. Each group of rotary support seats 19 is rotatably connected to the inner sleeve 10 respectively. The outer sleeve 11 axially penetrates and is threaded with a detachable fastening bolt 20. The outer wall of the inner sleeve 10 is radially provided with a fastening socket 21. The fastening bolt 20 can be plugged into the fastening socket 21 to achieve the fastening of the inner sleeve 10 and the outer sleeve 11. There is a spatial gap between the two rotary support seats 19 in each group of rotary support seats 19. After the outer sleeve 11 and the inner sleeve 10 are released from the fastening, they can move axially in the spatial gap to disengage and resume the engagement of the ring gear 12 and the rack 14.

[0026] Furthermore, since the distance between the front handle 15 and the front groove 16 is basically unchanged due to the size limitation of the No. 1 compression spring 18, the rotation angle of the claw head 8 and the claw rod 9 is also basically maintained unchanged. Therefore, at this time, the fastening bolt 20 is manually released from the fastening socket 21, and then the outer sleeve 11 is manually moved axially within the space gap of the rotating support seat 19, so that the ring gear 12 and the rack 14 are disengaged, and then the outer sleeve 11 is manually rotated, and then the meshing of the ring gear 12 and the rack 14 is restored, the initial meshing position of the rack 14 and the ring gear 12 can be changed, and then the fastening bolt 20 is restored to the fastening socket 21. , the angle between the claw head 8 and the support frame 1 in the initial state can be adjusted, and since the stroke of the rack 14 remains basically unchanged, after the front handle 15 is plugged into the front groove 16, the angle between the final position to which the claw head 8 is rotated backward and the support frame 1 changes. Moreover, since the claw head 8 rotates with the claw rod 9 as the axis, when the claw head 8 rotates to the final position, the front-to-rear distance between its farthest rearward part and the rear end of the suction cup 6 changes, thereby adapting to plates 54 of different thicknesses, so that the final position of the clamp does not interfere with the paving of the plate 54, that is, it does not cause the claw head 8 to contact the wall, causing the adhesive behind the plate 54 to be unable to contact the wall.

[0027] The push-pull mechanism includes a main cylinder 22, a main piston 23, a rear handle 24, a No. 2 compression spring 25, a rear groove 26, a No. 1 connecting nozzle 27, a sub-cylinder 28, a sub-piston 29, a connecting rod 30, a supporting rod 31, and a No. 2 connecting nozzle 32. The main cylinder 22 is fixed to the front and rear ends of the support frame 1. The main piston 23 is sealed and slidably connected in the front and rear ends of the main cylinder 22. The rear handle 24 and the No. 2 compression spring 25 are fixed to the front end of the main piston 23. The No. 2 compression spring 25 is fixed to the front end of the inner wall of the master cylinder 22. A rear groove 26 is provided at the rear end of the front of the master handle 2. The rear handle 24 can be inserted into the rear groove 26. The rear handle 24 has a tendency to move backward under the elastic repulsive force of the No. 2 compression spring 25. The master piston 23 divides the inner cavity of the master cylinder 22 into two chambers, front and back. The front of the master cylinder 22 is fixedly connected with four No. 1 connecting nozzles 27. Each of the No. 1 connecting nozzles 27 is connected to the front of the master cylinder 22. The chambers of the parts are connected, and each of the upper, lower, left and right parts of the support frame 1 is equipped with a secondary cylinder 28, and the secondary cylinder 28 is sealed and slidably connected to the secondary piston 29. The sliding direction of the secondary piston 29 is parallel to the axial direction of the adjacent claw rod 9, and the secondary piston 29 is fixed with a connecting rod 30, and the extension direction of the connecting rod 30 is parallel to the sliding direction of the secondary piston 29 in which it is located. The end of the connecting rod 30 in the extension direction is vertically fixed with a supporting rod 31, and the two ends of the supporting rod 31 are rotatably connected to the two claw rods 9. The secondary cylinder 28 is fixedly connected with a No. 2 connecting nozzle 32, and the No. 2 connecting nozzle 32 is connected to the chamber formed by the secondary piston 29 and the secondary cylinder 28. The front chamber formed by the main cylinder 22 and the main piston 23 is filled with hydraulic oil, and the chamber formed by the secondary cylinder 28 and the secondary piston 29 is filled with hydraulic oil. Each of the No. 2 connecting nozzles 32 is connected to each No. 1 connecting nozzle 27 through a surplus hydraulic hose for conveying hydraulic oil.

[0028] Furthermore, after pressing the front handle 15 backward and making the front handle 15 plug into the front groove 16, change the gripping position so that the tiger's mouth position clamps the main handle 2, keeps the front handle 15 plugged into the front groove 16, and then manually pull the rear handle 24 with four fingers to make the rear handle 24 move forward and almost completely plug into the rear groove 26, and then hold the front handle 15, the main handle 2 and the rear handle 24 at the same time. In the process of moving forward, the rear handle 24 drives the secondary piston 29 to move forward to squeeze the No. 2 compression spring 25 and the hydraulic oil, thereby The hydraulic oil in the chamber in the front part of the main cylinder body 22 enters the auxiliary cylinder body 28 through the No. 1 connecting nozzle 27, the hydraulic hose and the No. 2 connecting nozzle 32 to push the auxiliary piston 29, so that the clamping claws are moved closer to the middle of the support frame 1 through the connecting rod 30 and the supporting rod 31 to achieve clamping of the plate 54; when releasing the clamping, release the pull on the rear handle 24, and the main piston 23 can be moved backward under the elastic repulsive force of the No. 2 compression spring 25, so that the hydraulic oil is sucked back and the clamping claws are moved away from the middle of the support frame 1.

[0029] The push-pull mechanism also includes a transmission support seat 33, a transmission screw rod 34, and a hand wheel 35. A group of transmission support seats 33 is fixed on each of the upper, lower, left and right parts of the support frame 1. Two adjacent and coaxial transmission support seats 33 form a group. Each group of transmission support seats 33 is rotatably connected to a transmission screw rod 34. Each transmission screw rod 34 is parallel to the sliding direction of the adjacent secondary piston 29. Each transmission screw rod 34 is coaxially fixed with a hand wheel 35, and is respectively threadedly connected to the secondary cylinder body 28. The rear end of the secondary cylinder body 28 is in conflict with the support frame 1 and is in sliding connection.

[0030] Furthermore, since the movement stroke of the main piston 23 in the main cylinder body 22 remains basically unchanged, the movement stroke of the clamping jaws caused by the movement of the main piston 23 also remains basically unchanged. By manually rotating the hand wheel 35 forward and reverse, the transmission screw 34 can be rotated forward and reverse, thereby changing the position of the auxiliary cylinder body 28 relative to the support frame 1, and further changing the initial position of the connecting rod 30, the support rod 31 and the clamping jaws compared to the middle of the support frame 1, so that plates 54 of different lengths and widths can be clamped.

[0031] The suction device includes a guide frame 36, a slider 37, a No. 4 connecting nozzle 38, a tightening nut 39, and a No. 3 connecting nozzle 40. The support frame 1 includes a guide frame 36 fixed on the upper left, lower left, upper right, and lower right. Each of the guide frames 36 is arranged in a cross shape and is connected to a slider 37 for sliding along the front plane. The slider 37 passes through the front and back and is fixed with a No. 4 connecting nozzle 38 along the front and back directions. The rear part of the slider 37 is threadedly connected to the suction cup 6 to achieve detachable tightening. The No. 4 connecting nozzle 38 is connected to the suction cup 6, and each of the No. 4 connecting nozzles 38 is detachably threadedly connected with a clamping nut 39. The rear end of the clamping nut 39 can be pressed against the front end of the guide frame 36 to limit the position of the slider 37 relative to the guide frame 36. The rear part of the main cylinder body 22 is fixedly connected with four No. 3 connecting nozzles 40, and each of the No. 3 connecting nozzles 40 is respectively connected to the chamber at the rear of the main cylinder body 22, and is connected to each No. 4 connecting nozzle 38 through a surplus air pressure hose.

[0032] Furthermore, by rotating the clamping nut 39 and adjusting the clamping position of the clamping nut 39 on the guide frame 36, the position of the suction cup 6 relative to the support frame 1 can be adjusted to adapt to plates 54 of different sizes, so that the adsorption effect is more uniform, and the adsorption and grasping effect is improved. When the rear handle 24 is manually pulled forward, the air in the rear chamber of the main cylinder body 22 can be extracted through the main piston 23, thereby realizing the adsorption of the suction cup 6 and the plate 54. When the main piston 23 moves forward and resets, the exhaust effect can be released, thereby releasing the adsorption of the plate 54.

[0033] A vertical upper extension rod 41 is fixed to the top of the main handle 2, and a vertical lower extension rod 42 is fixed to the bottom end. A mobile power supply 43 is fixed to the top of the upper extension rod 41, and the mobile power supply 43 is fixed and electrically connected to a button switch 44. A wind tube 45 is fixed to the bottom end of the lower extension rod 42. Four No. 1 exhaust pipes 46 are fixedly connected to the upper part of the wind tube 45, and a fan 47 is fixed in the middle. The fan 47 is electrically connected to the button switch 44. A No. 2 exhaust pipe 48 is fixed to the upper, lower, left and right parts of the front end of the support frame 1, and a soft sponge pad 49 is flatly pasted and fixed to the upper, lower, left and right parts of the rear end of the support frame 1. The adsorption surface of the suction cup 6 and the middle position of the sponge pad 49 are in the same plane. The inner cavity of each No. 2 exhaust pipe 48 is respectively connected to each sponge pad 49, and is respectively connected to each No. 1 exhaust pipe 46 through the surplus air pressure hose.

[0034] Furthermore, before the suction cup 6 is fitted onto the surface of the plate 54, the rear end of the sponge pad 49 is brought into contact with the surface of the plate 54, and then the button switch 44 is pressed, and the mobile power supply 43 is used to provide power to the fan 47, so that the fan 47 rotates, thereby extracting the air around the sponge pad 49 through the No. 1 exhaust pipe 46, the air pressure hose, and the No. 2 exhaust pipe 48. During this period, the main handle 2, the upper extension rod 41 and the lower extension rod 42 are held to rotate the device, so that the sponge pad 49 forms a circular moving trajectory on the surface of the plate 54, and then the button switch 44 is pressed again to cut off the power supply, and then the suction cup 6 is fitted with the moving trajectory of the sponge pad 49. Due to the moving friction between the sponge pad 49 and the plate 54, and the suction of air, dust particles can be well adsorbed, thereby improving the adsorption and grasping effect of the suction cup 6 and the plate 54. When the sponge pad 49 needs to be replaced, it can be torn off and replaced.

[0035] Each group of jaws is respectively equipped with a projector, which includes a shell 51, a control circuit, a laser emitter 53 and a battery pack. Each group of jaws is respectively connected to the shell 51 for rotation. The shell 51 is fixed with a control circuit and a battery pack. A plurality of backward-tilted laser emitters 53 are respectively fixed at both ends of the shell 51. The projection points formed by the laser projection emitted by the laser emitter 53 in the front plane are on the same virtual straight line. The virtual straight line where the projection point formed by the laser emitter 53 in the front plane is located is in the same plane as the direction of the two adjacent claws 8.

[0036] Before using this device, check whether the virtual straight line where the laser projection point of the laser emitter 53 is located is in the same plane as the direction of the claw head 8. After ensuring this, when using the clamp to clamp the plate 54 for paving, the relative position of the projection point formed by the laser emitter 53 can be compared with the plate 54 that has been laid, so as to improve the accuracy of the paving position of the plate 54, that is, to improve the auxiliary positioning effect.

[0037] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
