DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] The present invention provides a device for measuring the flatness of a glass door based on laser, such as Figures 1 to 10As shown, it includes a bracket 1, a carrier plate 2 is slidably provided in the middle of the bracket 1, a scale line is provided on the top of the bracket 1, two support seats that can slide along the surface are provided on the bracket 1, and the connection method between the support seat and the bracket 1 is the connection method between the bracket and the support seat on the handheld measuring instrument for measuring the flatness of glass in the prior art. A lifting component for driving the lifting of the carrier plate 2 is provided on the carrier plate 2, and a measuring head 3 is provided on the carrier plate 2. The measuring head 3 is a laser measuring head on the glass flatness measuring instrument in the prior art, and the bottom end of the measuring head 3 extends to the bottom of the carrier plate 2. A movable groove is provided on one side of the bracket 1 close to the carrier plate 2, and a movable block 4 is provided in the movable groove. The bottom of the bracket 1 is provided with a There is an opening corresponding to the position of the movable block 4, a suction cup 5 is symmetrically fixedly installed on the bottom of the movable block 4, a channel 6 connected to the suction cup 5 is opened inside the movable block 4, a cylinder body 8 corresponding to the channel 6 is fixedly installed on the rear side of the bracket 1, the channel 6 and the cylinder body 8 are connected through a telescopic tube 7, a piston 9 is provided inside the cylinder body 8, a pull rod 10 is fixedly installed on the side of the piston 9 away from the bracket 1, one end of the pull rod 10 away from the piston 9 extends to the outside of the cylinder body 8, and the two pull rods 10 are fixedly connected by a connecting plate 11, a driving component for driving it to move in the vertical direction is provided on the outside of the movable block 4, and a protective component for protecting the suction cup 5 is provided at the bottom of the bracket 1.

[0033] When in use, the bracket 1 is held with the carrier plate 2 and the measuring head 3 to move along the glass door for measurement. When there is something that requires temporary departure and measurement interruption, the carrier plate 2 is driven by the lifting assembly to move with the measuring head 3 in the direction away from the glass door, and the movable block 4 is driven by the driving assembly to move with the suction cup 5 in the direction close to the glass door, and the protective assembly is pushed open, and finally the suction cup 5 contacts the surface of the glass door. Then, force is applied to the direction of the glass door by hand against the bracket 1, and the connecting plate 11 is pulled to move with the pull rod 10 and the piston 9 in the direction away from the bracket 1, so that the telescopic tube 7 and the channel 6 are used to extract the air inside the suction cup 5 to make the inside of it in a negative pressure state, and the air enters the cylinder 8, thereby being adsorbed on the glass door. At this time, the whole device is fixed on the glass door, and the positioning of the device is completed. At this time, the staff can leave. After the subsequent staff comes back, they can push the connecting plate 11 to reset it with the pull rod 10 and the piston 9, so that the air in the cylinder 8 is squeezed out. On the contrary, the air enters the suction cup 5, cancels the negative pressure state inside it, cancels the fixation, and then cooperates with the lifting component to drive the carrier plate 2 to reset, on the contrary, cooperates with the driving component to drive the movable block 4 to reset, and then the measurement can be continued. The protection component can perform dust protection on the suction cup 5 after the movable block 4 is reset. At this point, the position of the equipment on the glass door can be fixed when the measurement needs to be interrupted, so that when returning to continue the measurement, the measurement position can be known and the measurement can be continued. Therefore, there will be no situation where the measurement position is forgotten due to putting the equipment down and leaving the glass door, resulting in re-measurement, making the entire measurement more convenient;

[0034] The measuring head 3 is moved away from the glass door by the carrier plate 2, so that the bracket 1 is not squeezed too much during the process of the suction cup 5 adsorbing the glass door, which may cause the measuring head 3 to collide with the glass door and be damaged.

[0035] like Figure 2 As shown, the driving assembly includes a gear column 12 rotatably mounted inside the movable groove, and the movable block 4 and the carrier plate 2 are provided with teeth 13 that cooperate with the gear column 12 on one side close to the gear column 12 .

[0036] The carrier plate 2 rises to cooperate with the teeth 13 on its surface to drive the tooth column 12 to rotate, thereby cooperating with the teeth 13 on the surface of the movable block 4 to drive the movable block 4 to descend. Conversely, the carrier plate 2 descends to realize the ascending and resetting of the movable block 4.

[0037] like Figure 2 , Figure 5 and Figure 6 As shown, the protection component includes a frame 14 fixedly mounted on the bottom of the bracket 1, the number of the frame 14 is the same as the movable block 4, the frame 14 is located at the opening, and a shaft 16 is symmetrically mounted on the bottom of the frame 14 for rotation, a baffle 15 is fixedly sleeved on the outside of the shaft 16, and arc surfaces are arranged on opposite sides of the two baffles 15, and the arc surfaces are arranged upward, one end of the shaft 16 extends to the outside of the frame 14 and is sleeved with a first torsion spring 17, and the two ends of the first torsion spring 17 are fixedly connected to the shaft 16 and the frame 14 respectively.

[0038] The suction cup 5 descends and presses against the baffle 15, causing it to rotate downward with the shaft 16, and at the same time twists the first torsion spring 17 to twist and deform it, so that the suction cup 5 passes through the baffle 15 and contacts the glass door. When the movable block 4 is reset, the suction cup 5 moves away from the baffle 15, and the first torsion spring 17 releases its force to reset the shaft 16 and the baffle 15, so that the bottom of the frame 14 is closed, so that the suction cup 5 can be isolated from the outside world for dust prevention, so as to prevent the bottom of the suction cup 5 from being attached by external dust and affecting its adsorption force.

[0039] like Figure 8 and Fig.10 As shown, the lifting assembly includes a pair of support blocks 18 symmetrically fixedly mounted on the outside of the carrier plate 2, an electromagnet 20 is fixedly mounted on the top of the support block 18, a slide groove cooperating with the support block 18 is opened on the side of the bracket 1 close to the electromagnet 20, the support block 18 is slidably set in the slide groove, the top wall of the slide groove is made of iron, the top of the support block 18 is fixedly connected to the top wall of the slide groove by a spring 19, and a battery for powering the electromagnet 20 is provided inside the bracket 1, which is not shown in the figure.

[0040] The electromagnet 20 is energized to make it magnetic, so that it adsorbs the top wall of the slide slot, thereby causing the support block 18 and the carrier plate 2 to move away from the glass door. At the same time, the support block 18 compresses the spring 19 to deform it and generate a force. Finally, the electromagnet 20 is adsorbed and fixed to the top wall of the slide slot. The electromagnet 20 is powered off to make it lose its magnetism. The spring 19 releases its force to restore the support block 18, the electromagnet 20 and the carrier plate 2 to their original position.

[0041] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the bottom of the frame 14 is symmetrically fixed with side panels 21, a rotating rod 22 is symmetrically rotatably installed between the two side panels 21, a chain belt 23 is symmetrically sleeved between the two rotating rods 22, and the outside of the rotating rod 22 is provided with sprocket teeth matching with the chain belt 23, a shell 24 is fixedly installed between the two chain belts 23, a sponge block 25 is embedded in the shell 24, and the sponge block 25 can be removed for cleaning, and the outside of the rotating rod 22 is provided with a rotating component for driving it to rotate.

[0042] The baffle 15 can pass through between the side plate 21 and the rotating rod 22. When the carrier plate 2 moves in the direction away from the glass door, the rotating assembly drives the rotating rod 22 to rotate forward, so that the sprocket teeth rotate with the chain belt 23, thereby driving the shell 24 and the sponge block 25 to move. The initial position of the shell 24 is above the rotating rod 22. With the movement of the shell 24 and the sponge block 25, the sponge block 25 contacts the glass door downward, so that the area where the glass door contacts the suction cup 5 is wiped, the dust on the glass door is cleaned, and it is ensured that the suction cup 5 can be stably adsorbed on the glass door.

[0043] like Figure 1 and Figure 6 As shown, the rotating assembly includes a second torsion spring 26, one end of the rotating rod 22 close to the carrier plate 2 extends to the outside of the side plate 21, the second torsion spring 26 is sleeved on the outside of the rotating rod 22, and the two ends of the second torsion spring 26 are respectively fixedly connected to the side plate 21 and the rotating rod 22, and a wire taking-up groove is opened on the outside of the rotating rod 22 sleeved with the second torsion spring 26, and a pull rope 27 is fixedly connected in the wire taking-up groove. The pull rope 27 is wound in the wire taking-up groove, and the end of the pull rope 27 away from the rotating rod 22 is fixedly connected to the outer side of the carrier plate 2.

[0044] The carrier plate 2 moves in the direction away from the glass door and cooperates with the pull rope 27 to pull the rotating rod 22 to rotate, so that the second torsion spring 26 is twisted to cause its torsional deformation to generate a force, and the rotating rod 22 cooperates with the sprocket to drive the chain belt 23 to rotate, thereby driving the shell 24 and the sponge block 25 to move. The initial position of the shell 24 is above the rotating rod 22. With the movement of the shell 24 and the sponge block 25, the sponge block 25 contacts the glass door downward, so that the area where the glass door contacts the suction cup 5 is wiped. At the same time, the suction cup 5 is also descending. When the contact After the area is wiped, the suction cup 5 moves to the outside of the frame 14. As the carrier 2 continues to move, the shell 24 finally avoids the suction cup 5, and the suction cup 5 contacts the surface of the cleaned glass door. When the carrier 2 is reset, on the contrary, the second torsion spring 26 releases the force to rotate and reset the rotating rod 22, and the pull rope 27 is reeled up. At the same time, the movable block 4 and the suction cup 5 are also reset, and finally the suction cup 5, the shell 24, and the sponge block 25 are reset, so that the shell 24 and the sponge block 25 are located above the rotating rod 22 and will not affect the measurement.

[0045] like Figure 3 As shown, the suction cup 5 is specifically a vacuum suction cup.

[0046] This makes the adsorption effect between the suction cup 5 and the glass door better.

[0047] The method for detecting the flatness of a glass door using the above-mentioned laser-based flatness measurement device comprises the following steps:

[0048] S1. When in use, hold the bracket 1 with the carrier plate 2 and the measuring head 3 and move along the glass door for measurement. When you need to leave temporarily for something and interrupt the measurement, drive the carrier plate 2 with the measuring head 3 to move away from the glass door through the lifting component, and at the same time cooperate with the driving component to drive the movable block 4 with the suction cup 5 to move towards the glass door, push open the protection component, and finally the suction cup 5 will contact the surface of the glass door. Then, use your hand to apply force against the bracket 1 in the direction of the glass door, pull the connecting plate 11 to move it with the pull rod 10 and the piston 9 in the direction away from the bracket 1, so that the telescopic tube 7 and the channel 6 are used to extract the air inside the suction cup 5 to make it in a negative pressure state, and the air enters the cylinder 8, so that it is adsorbed on the glass door. At this time, the whole device is fixed on the glass door, and the positioning of the device is completed;

[0049] S2. The staff can leave at this time. When the staff comes back, they can push the connecting plate 11 to reset it with the pull rod 10 and the piston 9, so that the air in the cylinder 8 is squeezed outward. Otherwise, the air enters the suction cup 5, cancels the negative pressure state inside it, cancels the fixation, and then cooperates with the lifting component to drive the carrier plate 2 to reset. Otherwise, cooperate with the driving component to drive the movable block 4 to reset. At this time, the measurement can be continued. The protection component can protect the suction cup 5 from dust after the movable block 4 is reset.

[0050] S3. So far, the position of the device on the glass door can be fixed when the measurement needs to be interrupted, so that when you come back to continue the measurement, you can know the measurement position and continue the measurement. Therefore, there will be no situation where you cannot remember the measurement position due to putting the device down and leaving the glass door, which leads to re-measurement, making the whole measurement more convenient.

[0051] Working principle: When in use, hold the bracket 1 with the carrier plate 2 and the measuring head 3 and move along the glass door for measurement. When you need to leave temporarily and interrupt the measurement, energize the electromagnet 20 to make it magnetic, so that it can adsorb the top wall of the slide slot, thereby making the support block 18 and the carrier plate 2 move away from the glass door. At the same time, the support block 18 compresses the spring 19 to deform it and generate a force, so that the carrier plate 2 moves away from the glass door, and cooperates with the teeth 13 on its surface to drive the tooth column 12 to rotate, thereby cooperating with the teeth 13 on the surface of the movable block 4 to drive the movable block 4 to move downward in the direction close to the glass door, and then brings the suction cup 5 to the direction close to the glass door. The glass door moves in the direction of the suction cup 5, the suction cup 5 descends and presses against the baffle 15 to make it rotate downward with the shaft 16, and at the same time, the first torsion spring 17 is twisted to make it twist and deform, so that the suction cup 5 passes through the baffle 15 and contacts the glass door. Then, a force is applied to the direction of the glass door by hand to press against the bracket 1, and the connecting plate 11 is pulled to make it move with the pull rod 10 and the piston 9 in the direction away from the bracket 1, so that the telescopic tube 7 and the channel 6 are cooperated to extract the air inside the suction cup 5 to make the inside of it into a negative pressure state, and the air enters the cylinder 8, so that it is adsorbed on the glass door. At this time, the whole device is fixed on the glass door, and the positioning of the device is completed. At this time, the staff can leave. After the staff member comes back, he can push the connecting plate 11 to reset it with the pull rod 10 and the piston 9, so that the air in the cylinder 8 is squeezed out, otherwise, the air enters the suction cup 5, cancels the negative pressure state inside it, cancels the fixation, and cuts off the power to the electromagnet 20 to make it lose its magnetism. The spring 19 releases the force to reset the support block 18, the electromagnet 20, and the carrier plate 2. On the contrary, the carrier plate 2 descends to realize the rising reset of the movable block 4, and the suction cup 5 moves away from the baffle 15. The first torsion spring 17 releases the force to reset the shaft rod 16 and the baffle 15, so that the bottom of the frame 14 is closed, so that the suction cup 5 can be isolated from the outside world to prevent Dust is prevented from adhering to the bottom of the suction cup 5 by external dust, which would affect its adsorption force. Thus, when the measurement needs to be interrupted, the position of the device on the glass door can be fixed, so that when the measurement is returned to continue, the measurement position can be known and the measurement can be continued. Therefore, there will be no situation where the device is put down and away from the glass door, and the measurement position cannot be remembered and re-measured, making the whole measurement more convenient. The measuring head 3 is moved away from the glass door by the carrier plate 2, so that the bracket 1 will not be squeezed too much during the process of the suction cup 5 adsorbing the glass door, which would cause the measuring head 3 to collide with the glass door and be damaged.The carrier plate 2 moves in the direction away from the glass door, and cooperates with the pull rope 27 to pull the rotating rod 22 to rotate, so that the second torsion spring 26 is twisted to cause its torsional deformation to generate a force, and the rotating rod 22 cooperates with the sprocket to rotate the chain belt 23, thereby driving the shell 24 and the sponge block 25 to move. The initial position of the shell 24 is above the rotating rod 22. With the movement of the shell 24 and the sponge block 25, the sponge block 25 contacts the glass door downward, so that the area where the glass door contacts the suction cup 5 is wiped, and at the same time, the suction cup 5 is also descending. After wiping the contact area, the suction cup 5 moves at this time. To the outside of the frame 14, as the carrier 2 continues to move, the final shell 24 avoids the suction cup 5, and the suction cup 5 contacts the surface of the cleaned glass door. By cleaning the dust on the glass door, it is ensured that the suction cup 5 can be stably adsorbed on the glass door. When the carrier 2 is reset, on the contrary, the second torsion spring 26 releases the force to rotate and reset the rotating rod 22, and the pull rope 27 is rolled up. At the same time, the movable block 4 and the suction cup 5 are also reset, and finally the suction cup 5, the shell 24, and the sponge block 25 are reset, so that the shell 24 and the sponge block 25 are located above the rotating rod 22, which will not affect the measurement. ;

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.

8. A method for testing the flatness of a glass door using the laser-based flatness measurement device as described above, characterized in that: The steps include: S1. When in use, the support (1) is held with the carrier plate (2) and the measuring head (3) and moved along the glass door for measurement. When there is a need to leave temporarily and the measurement needs to be interrupted, the lifting component is used to drive the carrier plate (2) to move with the measuring head (3) in a direction away from the glass door. At the same time, the driving component is used to drive the movable block (4) to move with the suction cup (5) in a direction close to the glass door, and the protective component is pushed open. Finally, the suction cup (5) contacts the surface of the glass door. Then, a force is applied to the support (1) in the direction of the glass door by hand, and the connecting plate (11) is pulled to move with the pull rod (10) and the piston (9) in a direction away from the support (1). The telescopic tube (7) and the channel (6) are used to extract the air inside the suction cup (5) to make the inside of the suction cup (5) in a negative pressure state. The air enters the cylinder body (8) and is adsorbed on the glass door. At this time, the entire device is fixed on the glass door, and the positioning of the device is completed. S2. The staff can leave at this time. When the staff comes back, they can push the connecting plate (11) to reset it with the pull rod (10) and the piston (9), so that the air in the cylinder (8) is squeezed outward. Otherwise, the air enters the suction cup (5), cancels the negative pressure state inside it, cancels the fixation, and then cooperates with the lifting component to drive the carrier plate (2) to reset. Otherwise, cooperate with the driving component to drive the movable block (4) to reset. At this time, the measurement can continue. The protection component can protect the suction cup (5) from dust after the movable block (4) is reset. S3. So far, the position of the device on the glass door can be fixed when the measurement needs to be interrupted, so that when you come back to continue the measurement, you can know the measurement position and continue the measurement. Therefore, there will be no situation where you cannot remember the measurement position due to putting the device down and leaving the glass door, which leads to re-measurement, making the whole measurement more convenient.
