Description

Technical Field

[0001] The present invention relates to the technical field of laser measuring instrument structures, and particularly to a laser measuring instrument for measuring the thickness of glass bottles. Background Technique

[0002] The existing measuring instruments for the bottom thickness and wall thickness of glass bottles adopt the magnetic measurement principle. The inner and outer walls of the glass bottle are clamped by steel balls and monitoring probes, so as to complete the measurement of the wall thickness of the glass bottle; However, this device does not have a laser measurement function, and the measurement accuracy of laser measurement is more accurate and convenient compared with the magnetic measurement method. The magnetic measurement method is single and the measurement accuracy is not high. This is because during the clamping process of the steel ball and the measurement probe by magnetism, the magnetic method cannot guarantee the relative position of the steel ball and the measurement probe. The steel ball and the measurement probe are not at the same horizontal height, there is a height difference, resulting in inaccurate measurement accuracy. The added laser measurement function in this application has the advantage of keeping the laser measurement path at the same horizontal height. By synchronously cooperating the laser measurement function with the magnetic measurement, the measurement results are mutually verified.

[0003] Therefore, we propose a laser measuring instrument for measuring the thickness of glass bottles. Summary of the Invention

[0018] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-9 , the present invention provides a laser measuring instrument for measuring the thickness of a glass bottle, including an instrument body 1, a measuring probe 2 and a steel ball 3; Regarding the magnetic measurement principle of the instrument body 1: A steel ball 3 is placed in the glass bottle to be measured. When the steel ball 3 in the bottle to be measured approaches the measuring probe 2 on the instrument, the gravitational force of the magnetic field on the measuring probe 2 attracts the steel ball 3 to the inner wall of the glass bottle. At this time, the distance between the steel ball 3 and the measuring probe 2 is the measured thickness, and this thickness is inversely proportional to the action intensity of the magnetic field. By measuring the magnetic field intensity through the internal single-chip microcomputer system and correcting the linearity and compensating the temperature coefficient, the relevant thickness is measured; The instrument body 1 can specifically refer to the CH-1a type glass bottle thickness gauge manufactured by Shanghai Puwang Electronic Equipment Co., Ltd.

[0020] It further includes: a plurality of rotating plates 4 and connecting plates 5 that are rotatably matched with each other. A synchronizing member for synchronizing the rotation angles of the adjacent rotating plates 4 is provided between the adjacent rotating plates 4, and the synchronizing member is matched with the connecting plate 5; A fixed frame plate 6, one end of the fixed frame plate 6 is slidably matched with a transmitting sensor 7 that emits a laser beam. A receiving sensor 8 is provided at the end of one of the rotating plates 4 close to the transmitting sensor 7, and the synchronizing member makes the transmitting sensor 7 and the receiving sensor 8 located on the same relative horizontal plane; An active member that rotates with the rotating plate 4 is rotated on the fixed frame plate 6, and the active member rotates the rotating plate 4, and the receiving sensor 8 is brought closer to the transmitting sensor 7 in cooperation with the active member; An adjusting tube 9 that is inserted and matched with the instrument body 1, the adjusting tube 9 is slidably matched with the fixed frame plate 6, and an elastic pull rope 10 for fixing the glass bottle is provided on the adjusting tube 9; In this application, first, prepare for the measurement work to make the receiving sensor 8 enter the glass bottle, and the receiving sensor 8 is located on the outer wall of the glass bottle; Then move the glass bottle so that the outer wall of the glass bottle contacts the measuring probe 2, and the steel ball 3 is magnetically attracted by the measuring probe 2, and the two clamp the glass bottle to complete the measurement of the thickness of the glass bottle; Then, adjust the height of the fixed frame plate 6 so that the heights of the receiving sensor 8, the transmitting sensor 7 and the measuring probe 2 are the same; Rotate the threaded rod 20. Under the action of the synchronizing member, multiple rotating plates 4 rotate synchronously, causing the receiving sensor 8 to always move at the same horizontal height, so as to tightly press against the inner wall of the glass bottle, while the transmitting sensor 7 closely fits against the outer wall of the glass bottle, enabling the probe of the transmitting sensor 7 and the probe of the receiving sensor 8 to clamp the glass bottle; Finally, through the cooperation of the transmitting sensor 7 and the receiving sensor 8, the measurement is completed, and the results of the laser measurement and the magnetic measurement confirm each other; Among them, the basic principle of measuring the thickness of transparent glass usually involves using two laser displacement sensors: one transmitting sensor 7 emits a laser beam through the glass, and the other receiving sensor 8 receives the laser beam transmitted through the glass. By measuring the distance between the transmitting sensor 7 and the receiving sensor 8 and the propagation time or angular change of the laser beam inside the glass, the thickness of the glass can be calculated. For example, the laser displacement sensor MSE-TS803 produced by Yantai Morton Measurement and Control Technology Co., Ltd. can measure the thickness of transparent glass.

[0021] The bottom end of the adjusting tube 9 is fixedly connected with a mounting plate 17 installed on the instrument body 1. The installation position of the mounting plate 17 can be adjusted according to the diameter of the glass bottle, facilitating the measurement of glass bottles of various models and increasing the applicability of the device; Preparation work before measurement: First, move the fixed frame plate 6 upward along the adjusting tube 9, and then place the glass bottle vertically between the adjusting tube 9 and the measuring probe 2, and the glass bottle is located below the fixed frame plate 6 (the steel ball 3 is put into the glass bottle in advance); Then move the fixed frame plate 6 downward along the adjusting tube 9, so that one end of the U-shaped fixed frame plate 6 is inserted into the glass bottle, so that the receiving sensor 8 enters the glass bottle, while the receiving sensor 8 on the other end of the fixed frame plate 6 is located on the outer wall of the glass bottle; Finally, one end of the elastic pull rope 10 is sleeved on the outer wall of the glass bottle to complete the positioning work before measurement.

[0022] During the process of the measuring probe 2 and the steel ball 3, regarding the adjustment of the height of the measuring probe 2 to facilitate the measurement of the thickness of other parts at different heights of the glass bottle: This application also includes a plug-in board 11 connected to the measuring probe 2. A control board 12 is rotatably connected to the plug-in board 11. The measuring probe 2 is adjusted in height on the instrument body 1 through the plug-in board 11, and the measuring probe 2 is kept at a certain height through the control board 12.

[0023] The instrument body 1 is provided with a plug-in slot 25 that is in plug-in fit with the plug-in board 11. An embedding groove 26 is provided in the plug-in board 11. The control board 12 is in an arc shape. The top of the control board 12 is rotatably connected to the plug-in board 11 through a torsion spring, and the bottom of the control board 12 is in pressing fit with the inner wall of the plug-in slot 25.

[0024] When it is necessary to adjust the height of the measuring probe 2 to facilitate measuring the thickness of the upper part of the glass bottle, by rotating the arc section at the top of the plug-in plate 11 downward to overcome the elastic force of the torsion spring, the plug-in plate 11 is thus separated from the plug-in groove 25. Then, move the measuring probe 2 upward so that the measuring probe 2 moves upward along the outer surface of the glass bottle. Under the action of magnetic force, the steel ball 3 is driven to move. When the measuring probe 2 moves to the specified height, release the downward rotating force on the arc section at the top of the plug-in plate 11. Under the action of the torsion spring, the bottom of the plug-in plate 11 fits back into the plug-in groove 25 again. Under the pressing friction between the inner wall of the plug-in groove 25 and the plug-in plate 11, the height of the measuring probe 2 (the adjusted height) is stabilized. In this process, the measuring probe 2 drives the steel ball 3 to move synchronously through magnetic attraction, so that the measuring probe 2 acts on the steel ball 3 to clamp the glass wall, thereby measuring the thickness of the glass bottle. However, in this way, since there may be a difference in the height positions between the magnetically attracted steel ball 3 and the measuring probe 2, an error in the measured wall thickness will occur, that is, the line connecting the steel ball 3 and the measuring probe 2 is not perpendicular to the glass. Among them, except for the steel ball 3 and the measuring probe 2, other structures are made of non-magnetic materials.

[0025] Description of how to adjust the position of the fixed frame plate 6 up and down to adjust the heights of the receiving sensor 8 and the transmitting sensor 7 and complete the fixation: A sliding groove 13 is provided on the side of the adjusting tube 9 close to the measuring probe 2. The fixed frame plate 6 is a U-shaped plate. One end of the fixed frame plate 6 close to the measuring probe 2 is inserted into the glass bottle. The telescopic plate 14 slides in the sliding groove 13, and the end of the telescopic plate 14 is fixedly connected to the transmitting sensor 7. By moving the fixed frame plate 6 up and down, the fixed frame plate 6 moves up and down along the adjusting tube 9, and the telescopic plate 14 moves up and down along the sliding groove 13. Thus, the receiving sensor 8 and the transmitting sensor 7 at both ends of the fixed frame plate 6 move up and down synchronously. The receiving sensor 8 moves inside the glass bottle (not close to the inner wall of the glass bottle), and the transmitting sensor 7 fits against the outer wall of the glass bottle and slides along the outer wall of the glass bottle. A telescopic plate 14 with a compression spring inside is fixedly connected to the fixed frame plate 6. Due to the action of the compression spring in the telescopic plate 14, the transmitting sensor 7 closely fits against the outer wall of the glass bottle and slides along the outer wall of the glass bottle.

[0026] Description of making the rotating plate 4 rotate so that the receiving sensor 8 moves from the middle position of the glass bottle to press against the inner wall of the glass bottle: The synchronizing member includes a fixing plate 15. Rotating gears 16 that mesh with each other are connected to both ends of the fixing plate 15 in a rotating manner. The central axis of the gear 16 is fixedly connected to the rotating plate 4. The fixing plate 15 is also rotatably connected to the connecting plate 5. The corresponding rotating plate 4 and the connecting plate 5 are distributed in parallel. The gear 16, the rotating plate 4, the fixing plate 15, and the connecting plate 5 are distributed in a staggered manner. It should be noted that: the end of the rotating plate 4 and the end of the connecting plate 5 are always on the same vertical line, and the rotating plate 4 and the connecting plate 5 always remain parallel, and the lengths of the rotating plate 4 and the connecting plate 5 are the same, thus forming a parallelogram; When the rotating plate 4 on the fixed frame plate 6 rotates, it drives the corresponding connecting plate 5 to rotate, so as to ensure that the angle of the movable fixed plate 15 remains unchanged. The two meshing gears 16 rotate relative to the fixed plate 15, and the rotation angles are the same, so that the other rotating plates 4 and connecting plates 5 rotate at the same angle. The rotating plate 4 rotates, driving the receiving sensor 8 to move towards the inner wall of the glass bottle. Finally, the probe of the receiving sensor 8 presses against the inner wall of the glass bottle, and the bottoms of the multiple rotating plates 4 always remain at the same horizontal height, so that the probe of the receiving sensor 8, the bottom end of the rotating plate 4 and the probe of the transmitting sensor 7 are at the same horizontal height.

[0027] Description of the fixing method after the probes of the transmitting sensor 7 and the receiving sensor 8 clamp the glass bottle through the elastic pull rope 10: A sliding plate 18 is slidably fitted on the adjusting tube 9, and the elastic pull rope 10 passes through both ends of the sliding plate 18. A plurality of grooves 19 for cooperating with the elastic pull rope 10 are formed on the adjusting tube 9; When the probe of the transmitting sensor 7 tightly presses against the outer wall of the glass bottle, and the probe of the receiving sensor 8 tightly presses against the inner wall of the glass bottle, at this time, the glass bottle has a stable clamping effect; Then manually move the sliding plate 18 along the adjusting tube 9. The sliding plate 18 and the adjusting tube 9 are in frictional sliding. Without manually applying too much force, the sliding plate 18 cannot move along the adjusting tube 9. After the sliding position of the sliding plate 18 along the adjusting tube 9 is adjusted, the elastic pull rope 10 is pulled and sleeved on the outer wall of the glass bottle, and the elastic pull rope 10 is simultaneously clamped with the corresponding groove 19; It should be noted that: the elastic pull rope 10 in the present application can also be an elastic band with a larger width. The depth of the corresponding groove 19 corresponds to the elastic band, and the elastic band movably passes through the sliding plate 18. By using an elastic band with a larger width, the stability of the glass bottle is further ensured, and a stable connection relationship is constructed between the glass bottle, the fixed frame plate 6 and the adjusting tube 9, which is convenient for subsequent accurate measurement; Precautions for laser measurement: The probes of the receiving sensor 8 and the transmitting sensor 7 are both spherical structures. The probe of the receiving sensor 8 is fixedly connected to the rotating plate 4, and the center of the probe of the receiving sensor 8 corresponds to the end position of the rotating plate 4. The outer surfaces of the receiving sensor 8 and the transmitting sensor 7 are provided with transparent wear-resistant layers.

[0028] Although the rotating plate 4 rotates under the action of the synchronizing member, the height position of the top end of the rotating plate 4 changes, and the position of the bottom end of the rotating plate 4 always remains at the same horizontal height. Similarly, the probe center of the receiving sensor 8 (corresponding to the bottom end position of the rotating plate 4) also always remains at the same horizontal height. However, when the rotating plate 4 rotates, the inclination angle of the rotating plate 4 changes, and the probe of the corresponding receiving sensor 8 rotates synchronously and rotates with the probe center of the receiving sensor 8 as the center of rotation. In this application, the probe of the receiving sensor 8 is a spherical structure. When the receiving sensor 8 rotates in angle, the body of the receiving sensor 8 tilts in angle, but the position of the probe of the receiving sensor 8 does not change, and the distance and effect received by the spherical probe do not change.

[0029] Description of how to rotate the rotating plate 4 on the fixed frame plate 6 so that the receiving sensor 8 presses against the inner wall of the glass bottle: The movable member includes a threaded rod 20 threadedly connected to the fixed frame plate 6. The bottom end of the threaded rod 20 is sleeved with a connecting rod 21. The end of the connecting rod 21 is fixedly connected with a U-shaped block 22 that slides in the fixed frame plate 6. A rotating member is provided between the U-shaped block 22 and the rotating plate 4. The rotating plate 4 and the connecting plate 5 near the measuring probe 2 are both rotatably connected to the fixed frame plate 6. The rotating member includes a connecting plate 23 fixedly connected to the rotating plate 4. An articulated plate 24 is hinged between the connecting plate 23 and the U-shaped block 22; Rotate the threaded rod 20 to move the threaded rod 20 upward relative to the fixed frame plate 6, drive the connecting rod 21 to move upward, and thus drive the U-shaped block 22 to move upward. Since the U-shaped block 22 slides along the inner wall of the fixed frame plate 6, the U-shaped block 22 cannot rotate by itself, and the threaded rod 20 rotates relative to the connecting rod 21; The upward moving U-shaped block 22 drives the articulated plate 24 to rotate, thereby driving the connecting plate 23 to rotate. The top end of the connecting plate 23 rotates closer to the fixed frame plate 6, so that the inclined rotating plate 4 rotates to a horizontal state. Under the action of the synchronizing member, multiple rotating plates 4 rotate and unfold synchronously, so that the receiving sensor 8 moves in the direction close to the transmitting sensor 7, and the probe of the receiving sensor 8 presses against and contacts the inner wall of the glass bottle. Moreover, the height of the bottom end of the rotating plate 4 always remains at the same horizontal height, so that the spherical center position of the probe of the receiving sensor 8 and the spherical center position of the probe of the transmitting sensor 7 are kept at the same horizontal height, thereby clamping the glass bottle by the probe of the receiving sensor 8 and the probe of the transmitting sensor 7 to measure the thickness of the glass bottle; Wherein, the connecting rod 21 is a T-shaped structure, and the end of the connecting rod 21 is an elastic end that presses against the inner wall of the threaded rod 20. When the threaded rod 20 moves upward and rotates the rotating plate 4 through the connecting rod 21, by lifting the elastic end with elasticity by the threaded rod 20, the probe of the receiving sensor 8 is closely attached to the inner wall of the glass bottle.
