Description

Technical Field

[0001] The invention relates to the technical field of laser measuring instrument structures, in particular to a laser measuring instrument for measuring the thickness of glass bottles. Background Art

[0002] Existing instruments for measuring the bottom and wall thickness of glass bottles use the principle of magnetic measurement, which uses steel balls and monitoring probes to clamp the inner and outer walls of the glass bottle to measure the wall thickness of the glass bottle.

[0003] However, the device does not have a laser measurement function, and the measurement accuracy of laser measurement is more accurate and convenient than that of magnetic measurement. The magnetic measurement method is single and the measurement accuracy is not high. At this time, since the steel ball is clamped by magnetism with the measuring probe, the magnetic method cannot guarantee the relative position of the steel ball and the measuring probe. The steel ball and the measuring probe are not at the same horizontal height, and there is a height difference, which leads to the problem of 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. The laser measurement function and the magnetic measurement are synchronized to verify the measurement results.

[0004] To this end, we propose a laser measuring instrument for measuring the thickness of glass bottles. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-9 The present invention provides a laser measuring instrument for measuring the thickness of a glass bottle, comprising an instrument body 1, a measuring probe 2, and a steel ball 3;

[0035] 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 measured bottle is close to the measuring probe 2 on the instrument, the attraction of the magnetic field on the measuring probe 2 will attract 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 thickness to be measured. The thickness is inversely proportional to the strength of the magnetic field. The internal single-chip microcomputer system measures the magnetic field strength and corrects the linearity and compensates for the temperature coefficient to measure the relevant thickness.

[0036] The instrument body 1 may be specifically referred to as the CH-1a glass bottle thickness gauge manufactured by Shanghai Puwang Electronic Equipment Co., Ltd.

[0037] The invention also includes: a plurality of rotating plates 4 and connecting plates 5 that rotate with each other, a synchronizing member that synchronizes the rotation angles of the rotating plates 4 is provided between two adjacent rotating plates 4, and the synchronizing member cooperates with the connecting plates 5;

[0038] A fixed frame plate 6 is provided, and one end of the fixed frame plate 6 is slidably fitted with an emitting sensor 7 for emitting a laser beam. A receiving sensor 8 is provided at the end of one of the rotating plates 4 near the emitting sensor 7. Synchronous components ensure that the emitting sensor 7 and the receiving sensor 8 are located on the same relative horizontal plane.

[0039] A movable part that rotates and cooperates with the rotating plate 4 is rotated on the fixed frame plate 6. The movable part rotates the rotating plate 4, and cooperates with the movable part to make the receiving sensor 8 close to the transmitting sensor 7;

[0040] An adjusting tube 9 is plugged into the instrument body 1 and slides with the fixed frame 6. An elastic drawstring 10 for fixing the glass bottle is provided on the adjusting tube 9.

[0041] In this application, the measurement preparation is first performed to allow the receiving sensor 8 to enter the glass bottle, and the receiving sensor 8 is located on the outer wall of the glass bottle;

[0042] Then move the glass bottle so that the outer wall of the glass bottle contacts the measuring probe 2. The measuring probe 2 magnetically attracts the steel ball 3, and the two clamp the glass bottle to complete the measurement of the thickness of the glass bottle.

[0043] 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 consistent;

[0044] The threaded rod 20 is rotated, and under the action of the synchronization member, the multiple rotating plates 4 rotate synchronously, so that the receiving sensor 8 always moves at the same horizontal height, thereby tightly pressing against the inner wall of the glass bottle, and the transmitting sensor 7 is tightly attached to the outer wall of the glass bottle, so that the probe of the transmitting sensor 7 and the probe of the receiving sensor 8 clamp the glass bottle;

[0045] Finally, the measurement is completed through the cooperation of the transmitting sensor 7 and the receiving sensor 8, and the results of the laser measurement and the magnetic measurement are mutually confirmed;

[0046] Among them, the basic principle of measuring the thickness of transparent glass usually involves the use of two laser displacement sensors: a transmitting sensor 7 that transmits a laser beam through the glass, and a receiving sensor 8 that receives the laser beam that passes through the glass. By measuring the distance between the transmitting sensor 7 and the receiving sensor 8 and the propagation time or angle 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.

[0047] The bottom end of the adjusting tube 9 is fixedly connected to a mounting plate 17 mounted on the instrument body 1. The mounting position of the mounting plate 17 can be adjusted according to the diameter of the glass bottle, which is convenient for measuring various types of glass bottles and increases the applicability of the device.

[0048] Preparation before measurement: First, move the fixed frame plate 6 upward along the adjustment tube 9, then place the glass bottle vertically between the adjustment tube 9 and the measuring probe 2, with the glass bottle below the fixed frame plate 6 (the steel ball 3 is placed in the glass bottle in advance);

[0049] Then, the fixed frame plate 6 is moved downward along the adjustment 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, and the receiving sensor 8 on the other end of the fixed frame plate 6 is located on the outer wall of the glass bottle;

[0050] Finally, one end of the elastic drawstring 10 is sleeved on the outer wall of the glass bottle to complete the positioning work before measurement.

[0051] During the process of measuring the materials of the measuring probe 2 and the steel ball 3, instructions on adjusting the height of the measuring probe 2 to facilitate measuring the thickness of other parts of the glass bottle at other heights: This application also includes a plug-in board 11 connected to the measuring probe 2, and 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 maintained at a height through the control board 12.

[0052] The instrument body 1 is provided with a plug-in slot 25 that is plugged into the plug-in board 11, and an embedding slot 26 is provided in the plug-in board 11. The control board 12 has an arc-shaped structure. 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 pressed against the inner wall of the plug-in slot 25.

[0053] When it is necessary to adjust the height of the measuring probe 2 so as to measure the thickness of the upper part of the glass bottle, the arc section at the top of the plug-in plate 11 is rotated downward to overcome the elastic force of the torsion spring, thereby moving the plug-in plate 11 away from the plug-in slot 25. Then, the measuring probe 2 is moved upward so as to fit the outer surface of the glass bottle and move upward. Under the action of the magnetic force, the steel ball 3 is driven to move. When the measuring probe 2 moves to the specified height, the downward rotation force on the arc section at the top of the plug-in plate 11 is released. Under the action of the torsion spring, the bottom of the plug-in plate 11 is re-fitted into the plug-in slot 25. Under the action of the pressure and friction between the inner wall of the plug-in slot 25 and the plug-in plate 11, the height of the measuring probe 2 (the adjusted height) is stabilized.

[0054] In this process, the measuring probe 2 drives the steel ball 3 to move synchronously through magnetic attraction, so that the measuring probe 2 and the steel ball 3 act together to clamp the glass wall, thereby measuring the thickness of the glass bottle. However, this method may cause errors in the measured wall thickness due to the possible height difference between the magnetically attracted steel ball 3 and the measuring probe 2. That is, the line between the steel ball 3 and the measuring probe 2 is not perpendicular to the glass.

[0055] Except for the steel ball 3 and the measuring probe 2, other structures are made of non-magnetic materials.

[0056] Instructions for adjusting the position of the fixed frame plate 6 up and down to adjust the height of the receiving sensor 8 and the transmitting sensor 7 and complete the fixation: a chute 13 is provided on the side of the adjustment tube 9 close to the measuring probe 2. The fixed frame plate 6 is a U-shaped plate. The 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 chute 13. The end of the telescopic plate 14 is connected and fixed to the transmitting sensor 7.

[0057] By moving the fixed frame plate 6 up and down, the fixed frame plate 6 moves up and down along the adjustment tube 9, and the telescopic plate 14 moves up and down along the slide groove 13, so that the receiving sensor 8 and the transmitting sensor 7 located 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 is in contact with the outer wall of the glass bottle and slides along the outer wall of the glass bottle;

[0058] 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 inside the telescopic plate 14, the transmitting sensor 7 is closely attached to the outer wall of the glass bottle and slides along the outer wall of the glass bottle.

[0059] Regarding the explanation of rotating the rotating plate 4 so as to move the receiving sensor 8 from the middle of the glass bottle to press against the inner wall of the glass bottle: the synchronizing member includes a fixed plate 15, with gears 16 rotatably connected at both ends of the fixed plate 15 to mesh with each other. The central axis of the gear 16 is fixedly connected to the rotating plate 4, and the fixed plate 15 is also rotatably connected to the connecting plate 5. The corresponding rotating plate 4 and connecting plate 5 are arranged in parallel, and the gears 16, rotating plate 4, fixed plate 15 and connecting plate 5 are arranged in a staggered manner.

[0060] It is worth noting that the end of the rotating plate 4 and the end of the connecting plate 5 are always located on the same vertical line, and the rotating plate 4 and the connecting plate 5 are always parallel to each other. In addition, the lengths of the rotating plate 4 and the connecting plate 5 are the same, thus forming a parallelogram.

[0061] When the rotating plate 4 located on the fixed frame plate 6 rotates, it drives the corresponding connecting plate 5 to rotate, thereby ensuring that the movable fixed plate 15 maintains an angle unchanged, and the two meshing gears 16 rotate relative to the fixed plate 15, and the rotation angle is consistent, so that the other rotating plates 4 and the connecting plates 5 rotate at the same angle. The rotating plate 4 rotates, driving the receiving sensor 8 to move toward the inner wall of the glass bottle, and finally the probe of the receiving sensor 8 is pressed against the inner wall of the glass bottle, and the bottom ends of multiple rotating plates 4 are always maintained at the same horizontal height, so that the probe of the receiving sensor 8 is at the same horizontal height as the bottom end of the rotating plate 4 and the probe of the transmitting sensor 7.

[0062] Regarding the method for fixing the probes of the transmitting sensor 7 and the receiving sensor 8 by the elastic pull cord 10 after clamping the glass bottle: a slide 18 is slidably engaged with the adjustment tube 9, and the elastic pull cord 10 passes through both ends of the slide 18. The adjustment tube 9 is provided with a plurality of grooves 19 that cooperate with the elastic pull cord 10;

[0063] When the probe of the transmitting sensor 7 is pressed tightly against the outer wall of the glass bottle, and the probe of the receiving sensor 8 is pressed tightly against the inner wall of the glass bottle, the glass bottle is clamped and stabilized.

[0064] Then manually move the slide plate 18 along the adjusting tube 9. There is friction between the slide plate 18 and the adjusting tube 9. Without manual application of excessive force, the slide plate 18 cannot move along the adjusting tube 9. After the slide plate 18 is adjusted along the adjusting tube 9, the elastic drawstring 10 is pulled and sleeved on the outer wall of the glass bottle, and the elastic drawstring 10 is simultaneously engaged with the groove 19 at the corresponding position.

[0065] It is worth noting that the elastic drawstring 10 in the present application can also be an elastic band with a larger width. The corresponding groove 19 has a depth corresponding to that of the elastic band, and the elastic band movably passes through the slide plate 18. The wider elastic band further ensures the stability of the glass bottle, so that a stable connection is established between the glass bottle, the fixed frame plate 6 and the adjustment tube 9, which facilitates subsequent accurate measurement.

[0066] Notes on 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 connected and fixed to the rotating plate 4. 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 a transparent wear-resistant layer.

[0067] Although the rotating plate 4 rotates under the action of the synchronous part, the height position of the top end of the rotating plate 4 changes, and the bottom end position of the rotating plate 4 is always at the same horizontal height, the probe center of the similar receiving sensor 8 (corresponding to the bottom end position of the rotating plate 4) is also always at the same horizontal height, but the rotating plate 4 rotates, causing the inclination angle of the rotating plate 4 to change, and the corresponding probe of the 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, the body of the receiving sensor 8 tilts at an angle, but the probe position of the receiving sensor 8 does not change, and the receiving distance and effect of the spherical probe will not change.

[0068] Regarding how to rotate the rotating plate 4 located on the fixed frame plate 6 so as to press the receiving sensor 8 against the inner wall of the glass bottle: the movable part 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 to a U-shaped block 22 that slides in the fixed frame plate 6, a rotating part 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 part includes a connecting plate 23 fixedly connected to the rotating plate 4, and a hinged plate 24 is hinged between the connecting plate 23 and the U-shaped block 22;

[0069] The threaded rod 20 is rotated to move upward relative to the fixed frame plate 6, driving the connecting rod 21 to move upward, thereby driving the U-shaped block 22 to move upward. Since the U-shaped block 22 slides against the inner wall of the fixed frame plate 6, the U-shaped block 22 cannot rotate on its own, and the threaded rod 20 rotates relative to the connecting rod 21.

[0070] The upwardly moving U-shaped block 22 drives the hinged plate 24 to rotate, thereby driving the connecting plate 23 to rotate. The top end of the connecting plate 23 rotates toward the fixed frame plate 6, thereby rotating the inclined rotating plate 4 to a horizontal state. Under the action of the synchronizer, the multiple rotating plates 4 are synchronously rotated and unfolded, thereby causing the receiving sensor 8 to move toward the transmitting sensor 7, so that the probe of the receiving sensor 8 is pressed against the inner wall of the glass bottle, and the bottom end height of the rotating plate 4 is always maintained 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 maintained at the same horizontal height, so that the probe of the receiving sensor 8 and the probe of the transmitting sensor 7 clamp the glass bottle to measure the thickness of the glass bottle;

[0071] Among them, the connecting rod 21 is a T-shaped structure, and the end of the connecting rod 21 is an elastic end that is pressed against the inner wall of the threaded rod 20. When the threaded rod 20 moves upward and the rotating plate 4 is rotated through the connecting rod 21, the threaded rod 20 lifts the elastic end with elasticity, so that the probe of the receiving sensor 8 is tightly fitted on the inner wall of the glass bottle.
