Description

Technical Field

[0001] The present invention belongs to the technical field of laser measurement, and particularly relates to a device and method for measuring the flatness of a glass door based on laser measurement. Background Technique

[0002] A glass door is a special type of door leaf. Firstly, its thickness is not sufficient to be considered a solid door, and it does not belong to a special-shaped door. In fact, it is a special form of door leaf. The characteristics of a glass door are determined by the characteristics of the glass itself. For example, when tempered transparent glass is used, the door leaf has a transparent function, while when frosted glass is used, it has a semi-transparent function.

[0003] The flatness of a glass door needs to be measured, and a laser measurement device is required. When the existing laser glass door flatness measurement device is in use, when measuring a large-area glass door and temporarily leaving during the measurement process, the device needs to be put down to move it away from the glass door, resulting in subsequent staff not remembering the position where the measurement reached just now, and thus requiring re-measurement, which is rather inconvenient to use.

[0004] Therefore, it is very necessary to invent a device and method for measuring the flatness of a glass door based on laser measurement to solve the above problems. Summary of the Invention

[0007] Further, the driving assembly includes a tooth column rotatably installed inside the movable slot, and tooth teeth cooperating with the tooth column are provided on one side of the movable block and the carrier plate close to the tooth column.

[0008] Further, the protection assembly includes a frame body fixedly installed at the bottom of the bracket. The number of the frame bodies is the same as that of the movable blocks. The frame bodies are located at the openings. Shaft rods are symmetrically and rotatably installed at the bottom of the frame bodies. A baffle is fixedly sleeved outside the shaft rods. Arc surfaces are provided on the opposite sides of the two baffles, and the arc surfaces face upward. One end of the shaft rod extends to the outside of the frame body and is sleeved with a first torsion spring. The two ends of the first torsion spring are respectively fixedly connected with the shaft rod and the frame body.

[0009] Further, the lifting assembly includes a pair of support blocks symmetrically and fixedly installed outside the carrier plate. Electromagnets are fixedly installed at the tops of the support blocks. A sliding groove cooperating with the support blocks is opened on one side of the bracket close to the electromagnets. The support blocks are slidably arranged in the sliding grooves. The top wall of the sliding groove is made of iron. The tops of the support blocks are fixedly connected with the top wall of the sliding groove through springs.

[0010] Further, side plates are symmetrically and fixedly installed at the bottom of the frame body. A rotating rod is symmetrically and rotatably installed between the two side plates. A chain belt is symmetrically sleeved between the two rotating rods. Sprocket teeth cooperating with the chain belt are provided outside the rotating rod. A shell is fixedly installed between the two chain belts. A sponge block is embedded in the shell. A rotating assembly for driving the rotating rod to rotate is provided outside the rotating rod.

[0011] Further, the rotating assembly includes a second torsion spring. One end of the rotating rod close to the carrier plate extends to the outside of the side plate.

Then, apply force to the direction of the glass door to press against the bracket by hand, pull the connecting plate to move it with the pull rod and the piston away from the bracket, so that the telescopic tube and the channel can be used to extract the air inside the suction cup to make it in a negative pressure state, and the air enters the cylinder body, 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;

[0015] S2. The staff can leave at this time. When the staff comes back, they can push the connecting plate to reset it with the pull rod and the piston, so that the air in the cylinder is squeezed out. Otherwise, the air enters the suction cup, cancels the negative pressure state inside it, cancels the fixation, and then cooperates with the lifting component to drive the carrier plate to reset. Otherwise, cooperate with the driving component to drive the movable block to reset. At this time, the measurement can continue. The protection component can protect the suction cup from dust after the movable block is reset.

[0016] 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.

[0018] 1. The present invention can fix the position of the device on the glass door when it is necessary to interrupt the measurement, 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 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;

[0019] 2. The present invention can clean the contact area between the suction cup and the glass door while fixing the device, ensuring that the suction cup can be stably adsorbed on the glass door, thereby ensuring the stability of the device after positioning. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions 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 measurement, as Figures 1 to 10As shown in the figure, it includes a bracket 1. A carrier plate 2 is slidably arranged in the middle of the bracket 1. Scale lines are provided at the top of the bracket 1. There are two support seats that can slide along its surface on the bracket 1. The connection method between the support seats and the bracket 1 is the same as the connection method between the upper bracket and the support seats of a handheld measuring instrument for measuring the flatness of glass in the prior art. An elevating assembly for driving its lifting is provided on the carrier plate 2. A measuring head 3 is provided on the carrier plate 2. The measuring head 3 is a laser measuring head on a glass flatness measuring instrument in the prior art. The bottom end of the measuring head 3 extends below the carrier plate 2. An activity slot is opened on one side of the bracket 1 close to the carrier plate 2. An activity block 4 is arranged in the activity slot. An opening corresponding to the position of the activity block 4 is opened at the bottom of the bracket 1. Suction cups 5 are symmetrically and fixedly installed at the bottom of the activity block 4. A channel 6 communicating with the suction cups 5 is opened inside the activity block 4. A cylinder block 8 corresponding to the channel 6 is fixedly installed at the rear side of the bracket 1. The channel 6 and the cylinder block 8 are communicated through a telescopic tube 7. A piston 9 is arranged inside the cylinder block 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 outside the cylinder block 8. The two pull rods 10 are fixedly connected through a connecting plate 11. A driving assembly for driving it to move in the vertical direction is arranged outside the activity block 4. A protection assembly for protecting the suction cups 5 is arranged at the bottom of the bracket 1.

[0033] During use, hold the bracket 1 and move the carrier plate 2 and the measuring head 3 along the glass door for measurement. When there is something that requires a temporary leave and the measurement needs to be interrupted, at this time, drive the carrier plate 2 through the elevating assembly to make it drive the measuring head 3 to move away from the glass door. At the same time, cooperate with the driving assembly to drive the activity block 4 to drive the suction cups 5 to move towards the glass door, push open the protection assembly, and finally the suction cups 5 are in contact with the surface of the glass door. Then, apply a force towards the glass door against the bracket 1 with your hand, pull the connecting plate 11 to drive the pull rod 10 and the piston 9 to move away from the bracket 1, so that the air inside the suction cups 5 is pumped away through the telescopic tube 7 and the channel 6 to make its interior in a negative pressure state, and the air enters the cylinder block 8, thereby adsorbing on the glass door. At this time, the entire device is fixed on the glass door to complete the positioning of the device. At this time, the staff can leave. After the subsequent staff comes back, they can push the connecting plate 11 to drive the pull rod 10 and the piston 9 to reset, so that the air in the cylinder block 8 is squeezed outwards. On the contrary, the air enters the suction cups 5 to cancel the negative pressure state inside it and cancel the fixation. Then, cooperate with the elevating assembly to drive the carrier plate 2 to reset. On the contrary, cooperate with the driving assembly to drive the activity block 4 to reset. At this time, the measurement can be continued. The protection assembly can protect the suction cups 5 from dust after the activity block 4 is reset. Thus, when the measurement needs to be interrupted, the position of the device on the glass door can be fixed, so that when coming back 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 down the device and making it leave the glass door, resulting in re-measurement, making the entire measurement more convenient;

[0034] The carrier plate 2 drives the measuring head 3 to move away from the glass door, so that during the process of the suction cup 5 adsorbing the glass door, the extrusion force on the bracket 1 will not be too large, resulting in damage caused by the contact between the measuring head 3 and the glass door.

[0035] As Figure 2 shown, the driving component includes a tooth column 12 rotatably installed inside the movable slot. Tooth teeth 13 that cooperate with the tooth column 12 are provided on one side of the movable block 4 and the carrier plate 2 close to the tooth column 12.

[0036] The upward movement of the carrier plate 2 drives the rotation of the tooth column 12 in cooperation with the tooth teeth 13 on its surface, and then drives the downward movement of the movable block 4 in cooperation with the tooth teeth 13 on the surface of the movable block 4. Conversely, the downward movement of the carrier plate 2 can achieve the upward reset of the movable block 4.

[0037] As Figure 2 、 Figure 5 and Figure 6 shown, the protection component includes a frame body 14 fixedly installed at the bottom of the bracket 1. The number of the frame bodies 14 is the same as that of the movable blocks 4. The frame bodies 14 are located at the openings. Shaft rods 16 are symmetrically and rotatably installed at the bottom of the frame bodies 14. A baffle 15 is fixedly sleeved outside the shaft rods 16. Arc surfaces are provided on the opposite sides of the two baffles 15, and the arc surfaces face upward. One end of the shaft rod 16 extends outside the frame body 14 and is sleeved with a first torsion spring 17. The two ends of the first torsion spring 17 are fixedly connected to the shaft rod 16 and the frame body 14 respectively.

[0038] When the suction cup 5 descends and abuts against the baffle 15, it drives the shaft rod 16 to rotate downward, and at the same time twists the first torsion spring 17 to cause it to undergo torsional deformation, so that the suction cup 5 passes through the baffle 15 and abuts against the glass door. When the movable block 4 is reset, the suction cup 5 moves away from the baffle 15 accordingly, and the first torsion spring 17 releases the acting force to drive the shaft rod 16 and the baffle 15 to reset, so that the bottom of the frame body 14 is closed, enabling the suction cup 5 to be isolated from the outside, preventing dust, and avoiding the adhesion of dust from the outside to the bottom of the suction cup 5, which affects its adsorption force.

[0039] As Figure 8 and Figure 10 shown, the lifting component includes a pair of support blocks 18 symmetrically and fixedly installed on the outside of the carrier plate 2. An electromagnet 20 is fixedly installed on the top of the support blocks 18. A sliding groove that cooperates with the support blocks 18 is opened on one side of the bracket 1 close to the electromagnet 20. The support blocks 18 are slidably arranged in the sliding groove. The top wall of the sliding groove is made of iron, and the top of the support blocks 18 is fixedly connected to the top wall of the sliding groove through a spring 19. A storage battery (not shown in the figure) for supplying power to the electromagnet 20 is provided inside the bracket 1.

[0040] Energize the electromagnet 20 to make it magnetic, so that it adsorbs the top wall of the adsorption chute, 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 and generate a force. Finally, the electromagnet 20 adsorbs and fixes to the top wall of the chute. De-energize the electromagnet 20 to make it lose its magnetism, and the spring 19 releases the force to drive the support block 18, the electromagnet 20, and the carrier plate 2 to reset.

[0041] As Figure 1 , Figure 5 , Figure 6 and Figure 7 shown, side plates 21 are symmetrically and fixedly installed at the bottom of the frame body 14. Rotating rods 22 are symmetrically and rotatably installed between the two side plates 21. Chain belts 23 are symmetrically sleeved between the two rotating rods 22. Sprocket teeth for cooperating with the chain belts 23 are provided on the outer part of the rotating rods 22. A housing 24 is fixedly installed between the two chain belts 23. A sponge block 25 is embedded in the housing 24. The sponge block 25 can be removed for cleaning. A rotating assembly for driving the rotating rod 22 to rotate is provided on the outer part of the rotating rod 22.

[0042] The baffle 15 can pass through between the side plate 21 and the rotating rod 22. When the carrier plate 2 moves away from the glass door, it cooperates with the rotating assembly to drive the rotating rod 22 to rotate forward, causing the chain belt 23 to rotate with the cooperating sprocket teeth, thereby driving the housing 24 and the sponge block 25 to move. The initial position of the housing 24 is above the rotating rod 22. As the housing 24 and the sponge block 25 move, the sponge block 25 faces downward and contacts the glass door, so as to wipe the area where the glass door contacts the suction cup 5, clean the dust on the glass door, and ensure that the suction cup 5 can stably adsorb on the glass door.

[0043] As Figure 1 and Figure 6 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 rotating rod 22. Two ends of the second torsion spring 26 are respectively fixedly connected to the side plate 21 and the rotating rod 22. A wire groove is formed on the outer part of the rotating rod 22 sleeved with the second torsion spring 26. A pull rope 27 is fixedly connected in the wire groove. The pull rope 27 is wound in the wire groove. One 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 away from the glass door, and the pulling rope 27 drives the rotating rod 22 to rotate, causing the second torsion spring 26 to twist and deform to generate a force. The rotating rod 22 drives the chain belt 23 to rotate with the sprocket teeth, thereby driving the housing 24 and the sponge block 25 to move. The initial position of the housing 24 is above the rotating rod 22. As the housing 24 and the sponge block 25 move, the sponge block 25 moves downward to contact the glass door, so as to wipe the area where the glass door contacts the suction cup 5. At the same time, the suction cup 5 is also descending. After wiping the contact area, the suction cup 5 moves outside the frame 14 at this time. As the carrier plate 2 continues to move, finally the housing 24 avoids the suction cup 5, and the suction cup 5 abuts against the surface of the cleaned glass door. When the carrier plate 2 resets, on the contrary, the second torsion spring 26 releases the force and drives the rotating rod 22 to rotate and reset, winds up the pulling rope 27, and at the same time the movable block 4 and the suction cup 5 also reset, finally completing the reset of the suction cup 5, the housing 24 and the sponge block 25, so that the housing 24 and the sponge block 25 are located above the rotating rod 22 and will not affect the measurement.

[0045] As Figure 3 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] A method for detecting using the device for measuring the flatness of a glass door based on laser measurement as described above includes the following steps:

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

[0049] S2. At this time, the staff can leave. After the subsequent staff returns, they can push the connecting plate 11 to drive the pull rod 10 and the piston 9 to reset, so as to squeeze the air inside the cylinder body 8 outwards. On the contrary, the air enters the suction cup 5 to cancel the negative pressure state inside it and cancel the fixation. Then cooperate with the lifting assembly to drive the carrier plate 2 to reset, and on the contrary, cooperate with the driving assembly to drive the movable block 4 to reset. At this time, the measurement can be continued. After the movable block 4 resets, the protection assembly can provide dust protection for the suction cup 5;

[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 and move the carrier plate 2 and the measuring head 3 along the glass door for measurement. When it is necessary to temporarily leave for something and interrupt the measurement, energize the electromagnet 20 to make it magnetic, so that it adsorbs to the top wall of the adsorption chute, so that 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 and generate a force, and the carrier plate 2 moves away from the glass door. The teeth 13 on its surface cooperate to drive the tooth column 12 to rotate, so as to drive the movable block 4 to descend and move towards the glass door in cooperation with the teeth 13 on the surface of the movable block 4, and then drive the suction cup 5 to move towards the glass door. The suction cup 5 descends and abuts against the baffle 15 to make the shaft rod 16 rotate downward, and at the same time twist the first torsion spring 17 to make it torsionally deformed, so that the suction cup 5 passes through the baffle 15 and abuts against the glass door. Then apply a force towards the glass door against the bracket 1 with your hand, pull the connecting plate 11 to drive the pull rod 10 and the piston 9 to move away from the bracket 1, so that the air inside the suction cup 5 is pumped out through the telescopic tube 7 and the channel 6 to make it in a negative pressure state, and the air enters the cylinder body 8, so as to adsorb on the glass door. At this time, the whole device is fixed on the glass door to complete the positioning of the device. At this time, the staff can leave. After the subsequent staff comes back, the connecting plate 11 can be pushed to drive the pull rod 10 and the piston 9 to reset, so that the air in the cylinder body 8 is squeezed outwards. On the contrary, the air enters the suction cup 5 to cancel the negative pressure state inside it and cancel the fixation. The electromagnet 20 is powered off to lose its magnetism, and the spring 19 releases the force to drive the support block 18, the electromagnet 20 and the carrier plate 2 to reset. On the contrary, when the carrier plate 2 descends, the movable block 4 can be raised and reset, and the suction cup 5 moves away from the baffle 15 accordingly. The first torsion spring 17 releases the force to drive the shaft rod 16 and the baffle 15 to reset, so that the bottom of the frame body 14 is closed, so that the suction cup 5 can be isolated from the outside to prevent dust, and avoid the bottom of the suction cup 5 being attached by external dust, affecting its adsorption force. Thus, when it is necessary to interrupt the measurement, the position of the device on the glass door can be fixed, so that when coming back 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 down the device and making it leave the glass door, resulting in re-measurement, making the whole measurement more convenient; by moving the carrier plate 2 with the measuring head 3 away from the glass door, it is ensured that during the process of the suction cup 5 adsorbing the glass door, the extrusion force on the bracket 1 will not be too large, resulting in damage caused by the measuring head 3 abutting against the glass door;The carrier plate 2 moves away from the glass door, and the pulling rope 27 is cooperated to drive the rotating rod 22 to rotate, so that the second torsion spring 26 is twisted to generate a force. The rotating rod 22 cooperates with the sprocket teeth to drive the chain belt 23 to rotate, thereby driving the housing 24 and the sponge block 25 to move. The initial position of the housing 24 is above the rotating rod 22. As the housing 24 and the sponge block 25 move, the sponge block 25 contacts the glass door downward, so as to wipe the area where the glass door contacts the suction cup 5. At the same time, the suction cup 5 also descends. When the contact area is wiped, the suction cup 5 moves outside the frame 14 at this time. As the carrier plate 2 continues to move, the housing 24 finally avoids the suction cup 5, and the suction cup 5 abuts against the surface of the cleaned glass door. By cleaning the dust on the glass door, it is ensured that the suction cup 5 can stably adsorb on the glass door. When the carrier plate 2 is reset, on the contrary, the second torsion spring 26 releases the force to drive the rotating rod 22 to rotate and reset, wind up the pulling rope 27, and at the same time, the movable block 4 and the suction cup 5 are also reset. Finally, the reset of the suction cup 5, the housing 24 and the sponge block 25 is completed, so that the housing 24 and the sponge block 25 are located above the rotating rod 22 and do not affect the measurement.;

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
