[0022] Next, the technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0023] Refer to Figures 1 to 2 As shown, the present invention provides a glass bottle size measuring device.

[0024] The glass bottle size measuring device includes a base 100, a flipping mechanism 200, a rotating mechanism 300, a clamping mechanism 400, a translation mechanism 500, a lifting mechanism 600, an electronic micrometer 700 and a controller.

[0025] The base 100 is provided with a vertically arranged bracket. The flipping mechanism 200 is connected to the bracket of the base 100. The flipping mechanism 200 is provided with a first driving motor and a flipping arm. The first driving motor is installed on the bracket of the base 100. The output shaft of the first driving motor is connected to the flipping arm. The output shaft of the first driving motor extends in the left - right direction, so the first driving motor drives the flipping arm to rotate around an axis extending in the left - right direction.

[0026] The flipping arm is connected to the slewing mechanism 300. The flipping arm drives the slewing mechanism 300 to rotate about an axis extending in the left - right direction. The slewing mechanism 300 includes a second driving motor and a slewing disc. The second driving motor is arranged on the flipping arm, and the output shaft of the second driving motor is connected to the slewing disc. The second driving motor drives the slewing disc to rotate, and the rotation axis of the slewing disc is perpendicular to the rotation axis of the flipping arm.

[0027] The slewing disc is connected to the clamping mechanism 400. The clamping mechanism 400 is a three - jaw centering fixture. The rotation axis of the slewing disc coincides with the axis of the clamping mechanism 400. The clamping mechanism 400 is provided with three inner clamping blocks evenly distributed at equal intervals in the circumferential direction, and the inner clamping blocks move radially along the clamping mechanism 400.

[0028] During clamping, the three inner clamping blocks are inserted into the bottle mouth of the glass bottle 10. Then, the three inner clamping blocks are driven to move outward simultaneously to clamp the bottle mouth of the glass bottle 10, so that the axis of the glass bottle 10 coincides with the axis of the clamping mechanism 400. Then, the slewing disc drives the glass bottle 10 to rotate.

[0029] The flipping arm drives the slewing mechanism 300 to rotate about an axis extending in the left - right direction. Then, the flipping mechanism 200 drives the glass bottle 10 to rotate, making the glass bottle 10 vertically arranged or horizontally arranged.

[0030] Refer to Figure 1 As shown, the flipping arm rotates forward to be parallel to the horizontal plane, and the slewing mechanism 300 and the clamping mechanism 400 are located below the flipping arm, and the axes of the slewing mechanism 300 and the clamping mechanism 400 are arranged vertically. Then, the glass bottle 10 is vertically arranged.

[0031] Refer to Figure 2 As shown, the flipping arm rotates downward and is perpendicular to the horizontal plane, and the slewing mechanism 300 and the clamping mechanism 400 are located behind the flipping arm, and the axes of the slewing mechanism 300 and the clamping mechanism 400 are arranged horizontally. Then, the glass bottle 10 is horizontally arranged.

[0032] The translation mechanism 500, the lifting mechanism 600 and the electronic micrometer 700 are arranged behind the flipping mechanism 200. The translation mechanism 500 is installed on the base 100. The translation mechanism 500 is a screw drive mechanism. The translation mechanism 500 includes a third driving motor, a first screw rod, a first nut, a first slider and a first slide rail. The third driving motor is connected to the first screw rod. The first nut is sleeved outside the first screw rod. The first slide rail is arranged in the front - rear direction. The first slider is slidably arranged on the first slide rail. The first nut is connected to the first slider. Then, the third driving motor drives the first screw rod to rotate, and the first slider restricts the freedom degree of the first nut to rotate about its own axis. Then, the first screw rod drives the first nut to move in the front - rear direction. The first slider is connected to the lifting mechanism 600. Then, the translation mechanism 500 drives the lifting mechanism 600 to move in the front - rear direction by driving the first slider to move in the front - rear direction.

[0033] The lifting mechanism 600 is a screw drive mechanism. The lifting mechanism 600 includes a fourth driving motor, a second screw rod, a second nut, a second slider and a second slide rail. The fourth driving motor is connected to the second screw rod. The second nut is sleeved outside the second screw rod. The second slide rail is arranged in the up and down direction. The second slider is slidably arranged on the second slide rail. The second nut is connected to the second slider. Then the fourth driving motor drives the second screw rod to rotate, and the second slider restricts the freedom degree of the second nut to rotate around its own axis. Then the second screw rod drives the second nut to move in the up and down direction. The second slider is connected to the electronic micrometer 700.

[0034] The electronic micrometer 700 is a length measuring instrument that converts general linear displacement into the rotational movement of a pointer through gears or levers and then reads the value on a dial. And the electronic micrometer 700 can output measurement data to the processing system. In this embodiment, the controller is electrically connected to the electronic micrometer 700. The electronic micrometer 700 outputs the measurement data to the controller, and the controller stores the measurement data.

[0035] The electronic micrometer 700 is arranged in the front and back direction. The measuring rod of the electronic micrometer 700 is arranged in the front and back direction, and the measuring rod extends forward in front of the lifting mechanism 600.

[0036] Refer to Figure 1 As shown, the flipping mechanism 200 drives the glass bottle 10 to be arranged vertically. Then the translation mechanism 500 drives the lifting mechanism 600 and the electronic micrometer 700 to move to the rear side of the glass bottle 10. The measuring rod of the electronic micrometer 700 abuts against the side of the glass bottle 10. Then the lifting mechanism 600 drives the electronic micrometer 700 to move to the top of the side of the glass bottle 10.

[0037] In this embodiment, when the electronic micrometer 700 moves from the top of the side of the glass bottle 10 to the bottom of the side of the glass bottle 10, the electronic micrometer 700 can measure the side parameters of the glass bottle 10.

[0038] After the electronic micrometer 700 finishes measuring the side parameters of the glass bottle 10, the translation mechanism 500 drives the lifting mechanism 600 and the electronic micrometer 700 to move to the rear side of the glass bottle 10, so that the electronic micrometer 700 disengages from the side of the glass bottle 10, and the electronic micrometer 700 is far away from the rotation trajectory of the glass bottle 10, avoiding hitting the electronic micrometer 700 during the process of the flipping mechanism 200 driving the glass bottle 10 to flip along the left and right axis.

[0039] Refer to Figure 2As shown, the flipping mechanism 200 drives the glass bottle 10 to rotate downward so that the glass bottle 10 is arranged horizontally. The translation mechanism 500 drives the lifting mechanism 600 and the electronic dial indicator 700 to move to the rear of the bottom surface of the glass bottle 10. The translation mechanism 500 drives the measuring rod of the electronic dial indicator 700 to abut against the bottom surface of the glass bottle 10. Then, the lifting mechanism 600 drives the electronic dial indicator 700 to move to the top end of the bottom surface of the glass bottle 10.

[0040] In this embodiment, the lifting mechanism 600 drives the electronic dial indicator 700 to move from the top end of the bottom surface of the glass bottle 10 to the bottom end of the bottom surface of the glass bottle 10. The electronic dial indicator 700 can measure the bottom surface parameters of the glass bottle 10.

[0041] After the electronic dial indicator 700 finishes measuring the bottom surface parameters of the glass bottle 10, the translation mechanism 500 drives the lifting mechanism 600 and the electronic dial indicator 700 to move to the rear of the bottom surface of the glass bottle 10, so that the electronic dial indicator 700 disengages from the bottom surface of the glass bottle 10, and the electronic dial indicator 700 is moved away from the rotation trajectory of the glass bottle 10, avoiding hitting the electronic dial indicator 700 during the process of the flipping mechanism 200 driving the glass bottle 10 to flip along the left - right axis.

[0042] Then, the flipping mechanism 200 drives the glass bottle 10 to rotate backward so that the bottom surface of the glass bottle 10 faces upward, and the clamping mechanism 400 supports the mouth of the glass bottle 10 to keep the glass bottle 10 in place, facilitating the inspectors to pick up and place the glass bottle 10 from above the clamping mechanism 400 and avoiding the glass bottle 10 from falling downward when the clamping mechanism 400 releases the fixture.

[0043] Therefore, through the glass bottle size measuring device, the side dimension parameters and the bottom surface dimension parameters of the glass bottle 10 can be measured in the same device, without the need to transfer and clamp between multiple detection devices, improving the detection efficiency.

[0044] In some embodiments, the glass bottle size measuring device is further provided with a first grating scale and a second grating scale.

[0045] The first grating scale is arranged in the translation mechanism 500. The first grating scale measures the position of the translation mechanism 500 driving the lifting mechanism 600 to move in the front - rear direction, obtains the accurate position of the lifting mechanism 600 in the front - rear direction, and further obtains the accurate position of the electronic dial indicator 700 in the front - rear direction. The first grating scale is electrically connected to the controller, and the first grating scale sends the accurate position information of the electronic dial indicator 700 in the front - rear direction to the controller.

[0046] The second grating scale is arranged in the lifting mechanism 600. The second grating scale measures the position of the electronic dial indicator 700 moving in the up and down direction, obtains the accurate position of the electronic dial indicator 700 in the up and down direction, and is electrically connected to the controller. The second grating scale sends the accurate position information of the electronic dial indicator 700 in the up and down direction to the controller.

[0047] Referring to Figures 3 to 8 As shown, the present invention also provides a method for measuring the size of a glass bottle, which is applied to the glass bottle size measuring device as described in the above embodiments.

[0048] Referring to Figure 3 As shown, the measuring method includes the following steps.

[0049] Step S100, referring to Figure 1 As shown, the flipping arm of the flipping mechanism 200 rotates forward to be parallel to the horizontal plane, and the rotating mechanism 300 and the clamping mechanism 400 are located below the flipping arm, and the axes of the rotating mechanism 300 and the clamping mechanism 400 are arranged vertically, so the glass bottle 10 is arranged vertically.

[0050] Step S200, referring to Figure 1 As shown, the flipping mechanism 200 drives the glass bottle 10 to be arranged vertically, then the translation mechanism 500 drives the lifting mechanism 600 and the electronic dial indicator 700 to move to the rear of the side of the glass bottle 10, the translation mechanism 500 drives the measuring rod of the electronic dial indicator 700 to abut against the side of the glass bottle 10, and then the lifting mechanism 600 drives the electronic dial indicator 700 to move to the top of the side of the glass bottle 10.

[0051] In this embodiment, the lifting mechanism 600 drives the electronic dial indicator 700 to move from the top of the side of the glass bottle 10 to the bottom of the side of the glass bottle 10, and the electronic dial indicator 700 can measure the side parameters of the glass bottle 10.

[0052] After the electronic dial indicator 700 finishes measuring the side parameters of the glass bottle 10, the translation mechanism 500 drives the lifting mechanism 600 and the electronic dial indicator 700 to move to the rear of the side of the glass bottle 10, so that the electronic dial indicator 700 disengages from the side of the glass bottle 10, and the electronic dial indicator 700 is moved away from the rotation trajectory of the glass bottle 10, avoiding hitting the electronic dial indicator 700 during the process of the flipping mechanism 200 driving the glass bottle 10 to flip along the left and right axis.

[0053] Step S300, the flipping arm of the flipping mechanism 200 rotates downward and is perpendicular to the horizontal plane, and the rotating mechanism 300 and the clamping mechanism 400 are located behind the flipping arm, and the axes of the rotating mechanism 300 and the clamping mechanism 400 are arranged horizontally, so the glass bottle 10 is arranged horizontally.

[0054] Step S400, referring toFigure 2 As shown, the flipping mechanism 200 drives the glass bottle 10 to rotate downward so that the glass bottle 10 is arranged horizontally. The translation mechanism 500 drives the lifting mechanism 600 and the electronic dial indicator 700 to move to the rear of the bottom surface of the glass bottle 10. The translation mechanism 500 drives the measuring rod of the electronic dial indicator 700 to abut against the bottom surface of the glass bottle 10. Then, the lifting mechanism 600 drives the electronic dial indicator 700 to move to the top end of the bottom surface of the glass bottle 10.

[0055] In this embodiment, the lifting mechanism 600 drives the electronic dial indicator 700 to move from the top end of the bottom surface of the glass bottle 10 to the bottom end of the bottom surface of the glass bottle 10. The electronic dial indicator 700 can measure the bottom surface parameters of the glass bottle 10.

[0056] In some embodiments, referring to Figure 4 As shown, step S200 includes the following steps.

[0057] Step S210, the lifting mechanism 600 drives the electronic dial indicator 700 to move from the top end of the side surface of the glass bottle 10 to the bottom end of the side surface of the glass bottle 10. The electronic dial indicator 700 can measure the side surface parameters of the glass bottle 10. For example, if the lifting mechanism 600 drives the electronic dial indicator 700 to move uniformly from top to bottom, and the electronic dial indicator 700 measures data at a preset frequency, then during the process that the electronic dial indicator 700 moves from the top end of the side surface of the glass bottle 10 to the bottom end of the side surface of the glass bottle 10, the electronic dial indicator 700 will measure multiple data, and each data corresponds to the position information of the lifting mechanism 600 driving the electronic dial indicator 700. These data constitute the side profile data.

[0058] The smaller the speed of the lifting mechanism 600 driving the electronic dial indicator 700, the higher the preset frequency of the electronic dial indicator 700 for measurement, the more data obtained, and the more accurate the side profile data formed.

[0059] In this embodiment, before measuring the side surface of the glass bottle 10, the translation mechanism 500 moves the measuring rod of the electronic dial indicator 700 below the rotary mechanism 300 to make the measuring rod coincide with the axis position of the rotary mechanism 300. Then, the current position of the electronic dial indicator 700 is set as the origin. After that, when measuring the side surface of the glass bottle 10, the translation mechanism 500 drives the measuring rod of the electronic dial indicator 700 to move to the rear of the side surface of the glass bottle 10. Using the elastic measuring rod to abut against the side surface of the glass bottle 10, the distance data between the side surface of the glass bottle 10 and the origin can be measured. Multiple distance data constitute the side profile data.

[0060] Step S220: Establish a coordinate system with the vertical position of the electronic dial gauge 700 moved up and down by the lifting mechanism 600 as the ordinate and the data measured by the electronic dial gauge 700 as the abscissa. Plot each data point of the side profile data into the coordinate system to obtain a side profile image. Since the side profile image corresponds to the side of a longitudinal section of the glass bottle 10, the side parameters of the glass bottle 10 can be calculated based on the side profile image and the axisymmetric structural characteristics of the glass bottle 10 along the axis.

[0061] In some embodiments, as shown in Figure 4 Step S200 further includes the following steps.

[0062] Step S230: The mouth profile, body profile, and bottom profile of the glass bottle 10 can be determined from the side profile image. Therefore, the corresponding mouth diameter, body diameter, and bottom diameter can be calculated based on the coordinate points corresponding to each position of the side profile image.

[0063] For the transition curves between the mouth profile, body profile, and bottom profile in the side profile image, the transition fillet diameters between the mouth and the body and between the body and the bottom can be calculated by fitting the transition curves.

[0064] The mouth height, body height, and bottom height can be calculated from the height differences of the mouth profile, body profile, and bottom profile of the side profile image in the coordinate system.

[0065] In some embodiments, as shown in Figure 5 The measuring method further includes the following steps after performing step S100.

[0066] Step S240: If there is an external thread at the mouth position of the glass bottle 10, the measuring rod of the electronic dial gauge 700 can be set horizontally or switched to a vertical setting, and a horizontally extending abutting rod is added to the measuring rod. The measuring rod moves longitudinally to measure data. The abutting rod of the electronic dial gauge 700 is moved to the mouth thread of the glass bottle 10 through the translation mechanism 500 and the lifting mechanism 600. Pull the measuring rod upward to make the abutting rod of the electronic dial gauge 700 abut against the top of the mouth thread of the glass bottle 10, and the elastic force of the measuring rod makes the abutting rod tend to move downward. Then, the lifting mechanism 600 and the translation mechanism 500 remain stationary.

[0067] Step S250: Let the rotary mechanism 300 drive the glass bottle 10 to rotate 360° around its own axis. The abutting rod will move downward along the mouth thread of the glass bottle 10. After the rotary mechanism 300 drives the glass bottle 10 to rotate one circle, the distance change measured by the measuring rod of the electronic dial gauge 700 is the lead of the mouth thread, and the thread helix direction is judged.

[0068] In step S260, after obtaining the lead, the major diameter, minor diameter, and number of thread lines of the bottle mouth thread can be obtained from the side profile image, and then parameters such as the pitch diameter, pitch, and thread profile angle of the bottle mouth thread can be calculated based on the above data.

[0069] In some embodiments, referring to Figure 6 as shown in the measurement method, after performing step S100, the following steps are further included.

[0070] In step S270, after the measuring rod of the electronic micrometer 700 abuts against the side of the glass bottle 10, the glass bottle 10 can be rotated, and the distance data between the outer wall of a cross-section of the glass bottle 10 and the measuring rod can be measured. Since the measuring rod measures at a preset frequency, multiple distance data can be obtained, and these distance data correspond one-to-one to the rotation angle of the glass bottle 10 driven by the rotation mechanism 300.

[0071] In step S280, a coordinate system can be established with the distance data as the ordinate and the rotation angle of the glass bottle 10 as the abscissa, and a fitted curve or fitted straight line of the change of the distance data with the rotation angle can be drawn. This fitted curve or fitted straight line is the circumferential contour data, and the roundness of the glass bottle 10 can be calculated based on the circumferential contour data.

[0072] According to the above principle, the circumferential contour data of multiple different cross-sections of the glass bottle 10 are drawn, and the center positions of the multiple circumferential contour data are calculated respectively. The circumferential contour data is a fitted curve or a fitted straight line. Theoretically, if the axes of the glass bottle 10 in multiple different cross-sections coincide, the multiple circumferential contour data are fitted straight lines and the ordinates where the fitted straight lines are located should coincide. Substituting the ordinates where the two circumferential contour data are located into R1 and R2 respectively, according to the concentricity formula: concentricity = (R1 - R2) ÷ R1, it can be known that the concentricity is 0; however, in fact, there may be slight deviations in the ordinates where the multiple circumferential contour data are located. It is necessary to calculate the corresponding average value of the ordinate for each circumferential contour data, and substitute any two circumferential contour data into the concentricity formula to calculate the concentricity of the glass bottle 10 at the corresponding two different cross-sections.

[0073] In some embodiments, referring to Figure 7 as shown in step S400, controlling the electronic micrometer 700 to obtain the bottom surface parameters of the glass bottle 10 includes the following steps.

[0074] Step S410: The lifting mechanism 600 drives the electronic dial indicator 700 to move from the top end to the bottom end of the bottom surface of the glass bottle 10. The electronic dial indicator 700 can measure the bottom surface parameters of the glass bottle 10. For example, the lifting mechanism 600 drives the electronic dial indicator 700 to move uniformly from top to bottom, and the electronic dial indicator 700 measures data at a preset frequency. During the process that the electronic dial indicator 700 moves from the top end to the bottom end of the bottom surface of the glass bottle 10, the electronic dial indicator 700 will measure multiple data, and each data corresponds one-to-one to the position information of the lifting mechanism 600 driving the electronic dial indicator 700. These data constitute the bottom surface profile data.

[0075] The smaller the speed of the lifting mechanism 600 driving the electronic dial indicator 700, the higher the preset frequency of the electronic dial indicator 700 for measurement, the more data obtained, and the more accurate the bottom surface profile data formed.

[0076] Step S420: Establish a coordinate system with the up-and-down movement position of the lifting mechanism 600 driving the electronic dial indicator 700 as the abscissa and the data measured by the electronic dial indicator 700 as the ordinate. Plot each data point of the bottom surface profile data in the coordinate system to obtain the bottom surface profile image. Since the bottom surface profile image corresponds to the bottom surface of a longitudinal section of the glass bottle 10, the bottom surface parameters of the glass bottle 10 can be calculated based on the bottom surface profile image and the structural characteristics of the glass bottle 10 being axisymmetric.

[0077] In some embodiments, referring to Figure 7 as shown, step S400: Controlling the electronic dial indicator 700 to obtain the bottom surface parameters of the glass bottle 10 further includes the following steps.

[0078] Step S430: It can be seen from the bottom surface profile image in the coordinate system that the bottom surface of the glass bottle 10 is concave upward. Therefore, the concave surface height and concave surface radian of the bottle bottom can be calculated.

[0079] In some embodiments, referring to Figure 8 as shown, the measuring method further includes the following steps after performing step S300.

[0080] Step S440: Through the translation mechanism 500 and the lifting mechanism 600, the electronic dial indicator 700 is abutted against any lowest position of the bottom surface of the glass bottle 10, that is, Figure 2 the rearmost position of the bottom surface of the glass bottle 10 in , and then the rotary mechanism 300 drives the glass bottle 10 to rotate.

[0081] In step S450, during the rotation of the glass bottle 10, the electronic micrometer 700 measures the distance data at a preset frequency. Each distance data corresponds to the rotation angle of the glass bottle 10 one by one. A coordinate system is established with the rotation angle as the horizontal coordinate and the distance data as the vertical coordinate. The coordinate points corresponding to the above distance data and the rotation angle are plotted in the coordinate system, and all the coordinate points are fitted into a straight line or a curve. This fitted straight line or fitted curve is the bottom surface rotation data. Based on the bottom surface rotation data, the bottom surface flatness of the lowest point of the glass bottle 10 for contacting the support surface can be calculated.

[0082] For example, in this embodiment, the average value and the deviation value are calculated from the bottom surface rotation data, and the deviation value is used as the bottom surface flatness. The bottom surface flatness can be judged by the size of the deviation value.
