Description

Technical Field

[0001] The present invention belongs to the technical field of glass bottle production inspection, and relates to the inspection of the bottom of a glass bottle. Specifically, it is a device and method for detecting the depth of the bottle bottom and a corresponding device for detecting the mouth diameter of the bottle neck. Background Art

[0002] Currently, for the quality inspection of the mouth of a glass bottle, the optical image inspection method is often used, that is, a light source set at the corresponding inspection position and a camera located above the inspection position are used to take a picture of the bottle body, and then the electronic control system calculates the dimensions of each part of the bottle body and determines whether there are external defects, so as to obtain the inspection result of whether the quality of the bottle body meets the standard. Although this quality inspection method can detect external dimensions such as the outer diameter of the mouth, the outer diameter of the bottle body, the length of the bottle body, the wall thickness of the mouth, and the outer diameter of the bottle neck, it does not detect the bottom depth.

[0003] The bottom depth is the depth of the concave notch at the bottom of the bottle. The notch is located at the bottom of the bottle and is a dome-shaped recess towards the inside of the bottle. In the production control of glass bottles, the bottom depth is an important parameter for judging the quality of the bottle body. The detected bottom depth value is the distance from the bottom surface of the bottle bottom to the bottom end of the concave notch on the axis of the bottle body. In the prior art, due to the lack of special inspection equipment, the bottom depth is often directly measured manually using a dial indicator. This inspection method has low inspection efficiency and cannot be used in the batch production inspection of glass bottles. Moreover, the accuracy of the inspection result is easily affected by manual operation. Summary of the Invention

[0026] The present invention also provides a method for detecting the depth of the bottom of a bottle implemented by using the above-mentioned device for detecting the depth of the bottom of a bottle. The technical solution is as follows:

[0027] It includes the following steps:

[0028] S1. Dynamic positioning of the starting point

[0030] The pushing port assembly and the bottle fixing assembly position the bottle to be inspected and position the pushing starting point of the bottom pushing assembly; At this time, the distance between the working end of the pushing port assembly at the pushing port position and the driving surface of the bottom pushing assembly at the pushing starting point is a fixed value L;

[0031] S2. Acquisition of displacement data

[0032] Under the condition that the pushing port assembly and the bottle fixing assembly position the bottle to be inspected, the driving surface of the bottom pushing assembly moves from the pushing starting point to the pushing end point where it contacts the bottom surface of the bottle bottom;

[0033] The detection component detects the moving distance value S of the driving surface of the bottom pushing assembly moving from the pushing starting point to the pushing end point;

[0037] As a limitation of the present invention,

[0038] S2. Acquisition of displacement data

[0039] Under the condition that the pushing port assembly and the bottle fixing assembly position the bottle to be inspected, after the driving surface of the bottom pushing assembly moves from the pushing starting point to the pushing end point where it contacts the bottom surface of the bottle bottom, the bottom pushing reset member drives the bottom pushing assembly to reset, and a reset distance equal to the moving distance is generated during the reset process of the bottom pushing assembly;

[0042] Obtain the depth of the concave notch at the bottom of the bottle = L - B,

[0043] Judge whether the depth value of the concave notch at the bottom of the bottle to be inspected meets the standard.

[0044] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects achieved by the present invention are:

[0045] (1) The bottom depth detection device of the present invention provides a brand-new special detection method for the bottom depth, which uses a mechanical structure to achieve efficient and high-quality detection of the bottom depth. That is, through the positioning of the bottle-fixing assembly and the pushing port assembly on the bottle to be detected, the dynamic positioning of the pushing starting position of the bottom-pushing assembly is realized. By using the fact that the distance between the working end of the pushing port assembly at the pushing port position and the driving surface of the bottom-pushing assembly at the pushing starting position is a fixed value L, and detecting the moving distance value S of the bottom-pushing assembly from the pushing starting position to the pushing ending position, the bottom depth d = L - S can be obtained, so as to judge whether the depth of the bottle bottom notch meets the standard. Further, the present invention utilizes the fact that the moving distance value S of the bottom-pushing assembly is equal to the reset distance value B generated when it is reset, converts the moving distance value S into the reset distance value B of the bottom-pushing assembly, and the bottom depth can be obtained by directly detecting the reset distance value B with the bottom bottle sensor. The present invention is applicable to the efficient detection of the bottom depth on the bottle body production control line, can ensure the accuracy of the detection result, is convenient for timely removing unqualified products, reducing the product unqualified rate, and improving the product quality.

[0046] (2) The bottom depth and bottle mouth diameter detection device of the present invention realizes the simultaneous detection of the bottom depth and the bottle mouth diameter of the bottle to be detected at one detection position. In the bottom depth detection, the positioning of the bottle to be detected in the bottle mouth diameter detection is utilized, and in the bottle mouth diameter detection, the driving force on the bottle to be detected in the bottom depth detection is utilized. By using the interaction relationship between the structures, not only the detection steps are simplified, the detection result can be obtained quickly, but also the occupied space is saved and the production cost is reduced.

[0047] (3) The bottle mouth diameter detection structure of the present invention completely changes the existing method of detecting the inner diameter of the bottle mouth by optical image, and provides a brand-new method of detecting the inner diameter of the bottle mouth by using a mechanical structure, that is, the bottle-pushing assembly pushes the bottle to be detected to move. By using the fact that the positioning position of the bottle to be detected on the bottle-top component corresponds one-to-one with the diameter of the bottle to be detected, it can be obtained whether the inner diameter of the bottle mouth meets the standard according to the positioning position of the bottle to be detected on the bottle-top component. The present invention is convenient to achieve the accuracy of the detection of the inner diameter of the bottle mouth, timely remove unqualified products, ensure the accuracy of the detection result, reduce the product unqualified rate, improve the product quality, and save the occupied space. At the same time, the present invention detects the reset distance of the retracting component through the bottle mouth sensor, and converts the corresponding relationship between the positioning position of the bottle to be detected on the bottle-top component and the bottle mouth diameter into the corresponding relationship between the retracting distance value and the inner diameter of the bottle mouth, so as to achieve the detection result of efficiently and accurately obtaining whether the inner diameter of the bottle mouth meets the standard.

[0048] The present invention is applicable to the production control of glass bottles and is used to detect the bottom depth. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0057] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and understanding the present invention, and are not used to limit the present invention.

[0058] Embodiment 1 A bottle bottom depth detection device and detection method

[0059] This embodiment provides a new special detection method for bottom depth, which uses a mechanical structure to achieve efficient and high-quality detection of bottom depth. That is, the bottle body to be inspected is positioned by the bottle fixing assembly and the push-mouth assembly, and the bottom pushing starting point of the bottom pushing assembly is dynamically positioned at the same time. The distance from the working end of the push-mouth assembly at the push-mouth position to the driving surface of the bottom pushing assembly at the bottom pushing starting point is used as a fixed value L, and the moving distance value S of the bottom pushing assembly from the bottom pushing starting point to the bottom pushing end point is detected, so that the bottom depth d=LS can be obtained, thereby judging whether the depth of the bottle bottom recess meets the standard.

[0060] like Figures 1 to 2 As shown, this embodiment includes a bottle fixing assembly and a bottle pushing assembly fixedly mounted on a frame. The bottle pushing assembly includes a bottom pushing assembly, a mouth pushing assembly and a detection assembly.

[0061] 1. Bottle fixing assembly

[0062] The bottle fixing assembly is used to position the inspected bottle. The bottle fixing assembly can use a baffle to position the bottle mouth, or a clamp ring to position the bottle neck, etc. The bottle fixing position of the bottle fixing assembly refers to the position where the inspected bottle is positioned, and the inspected bottle will no longer move at this position.

[0063] 2. Push-mouth assembly

[0064] The push-mouth assembly is used to dynamically locate the bottom push starting point of the push-bottom assembly together with the bottle fixing assembly, that is, while the push-mouth assembly and the bottle fixing assembly locate the inspected bottle body, the push-bottom push starting point of the push-bottom assembly is dynamically located. Figure 2 As shown, at this time, the opening pushing position of the opening pushing assembly, the bottle fixing position of the bottle fixing assembly and the bottom pushing starting position of the bottom pushing assembly correspond to each other.

[0065] The working end of the push-mouth assembly corresponds to the notch on the bottom of the bottle body to be inspected on the detection position. The push-mouth position of the push-mouth assembly refers to the position where the working end of the push-mouth assembly contacts the bottom of the notch on the bottom of the bottle. The push-mouth assembly in the push-mouth position can push the inspected bottle body forward to the bottle-fixing position of the bottle-fixing assembly and then position the inspected bottle body. It can also make the inspected bottle body directly located at the bottle-fixing position, and then the push-mouth assembly moves to the push-mouth position to press against the bottom center of the notch on the bottom of the bottle to position the inspected bottle body.

[0066] The push-out assembly includes a push rod 38, which can be directly and movably connected to the power output end of the push-out driver 32. Of course, the push rod 38 can also be driven and moved by the push rod driver alone. The working end of the push rod 38 is the end that contacts the bottom end of the notch. The shape of the working end of the push rod 38 is adapted to the shape of the notch surface. The working end of the push rod 38 can be convex or concave.

[0067] 3. Push bottom assembly

[0068] The bottom pushing component is used to generate a moving distance when moving from the bottom pushing starting position to the bottom pushing ending position where it contacts the bottom surface of the bottle after the bottle is positioned. The driving surface of the bottom pushing component is arranged corresponding to the bottom surface of the inspected bottle body at the detection position. The bottom pushing starting position of the bottom pushing component refers to the position where the working end of the pushing port component abuts against the bottom end of the concave notch of the inspected bottle body and the driving surface of the bottom pushing component when the bottle positioning assembly positions the inspected bottle body. At this time, the driving surface of the bottom pushing component has not contacted the bottom surface of the inspected bottle body, and the distance between the driving surface of the bottom pushing component and the bottom surface of the inspected bottle body is S. The bottom pushing ending position of the bottom pushing component refers to the position where the driving surface of the bottom pushing component moves to contact the bottom surface of the inspected bottle body. At this time, the distance between the driving surface of the bottom pushing component and the bottom surface of the inspected bottle body is 0.

[0069] The bottom pushing component includes a bottom pushing driver 32 and a pushing block 31 fixedly installed at the power output end of the bottom pushing driver 32. The driving surface of the pushing block 31 is arranged corresponding to the bottom surface of the inspected bottle body at the detection position. The bottom pushing driver 32 can adopt a linear driver in the prior art.

[0070] In this embodiment, the tail end (i.e., the working end) of the push rod 38 passes through the concave notch of the bottom of the inspected bottle body at the corresponding detection position of the pushing block 31, that is, the push rod 38 is slidably connected to the pushing block 31 so that the push rod 38 is indirectly fixedly installed on the bottom pushing driver 32. When the pushing block 31 is at the bottom pushing starting position, the distance between the working end of the push rod 38 and the driving surface of the pushing block 31 is a fixed value L, and L = bottom depth + moving distance value S.

[0071] IV. Detection Component

[0072] The detection component is used to detect the moving distance value of the bottom pushing component, directly detect the moving distance value of the bottom pushing component moving from the bottom pushing starting position to the bottom pushing ending position by using a sensor device, and obtain the depth of the concave notch at the bottom of the bottle by using the corresponding relationship of L = bottom depth + moving distance value S.

[0073] V. Working Process

[0074] When using this embodiment under the control of the controller, the method for detecting the bottom depth of the bottle includes the following steps:

[0075] S1. Dynamic positioning at the starting position

[0076] The working end of the pushing port component moves to the pushing port position where it contacts the bottom end of the concave notch of the inspected bottle body; the pushing port component and the bottle positioning assembly position the inspected bottle body and position the bottom pushing starting position of the bottom pushing component; at this time, the distance between the working end of the pushing port component at the pushing port position and the driving surface of the bottom pushing component at the bottom pushing starting position is a fixed value L. Specifically:

[0077] S11. Pushing the bottle mouth: The bottom-pushing driver drives the push rod 38 and the push block 31 to move forward together. The working end of the push rod 38 extends into the notch, contacts the center of the bottom of the notch, and pushes the bottle under inspection forward. At this time, the distance from the working end of the push rod 38 to the driving surface of the push block 31 is L;

[0078] S12. Positioning the bottle: During the process of the push rod 38 pushing the bottle under inspection forward, the bottle positioning assembly positions the bottle mouth of the bottle under inspection. The bottle under inspection is clamped between the bottle positioning assembly and the push rod 38, and the driving surface of the push block 31 is positioned at a distance S from the bottom surface of the bottle bottom. As Figure 2 shown, at this time, the bottle mouth pushing assembly is in the bottle mouth pushing position, the bottom-pushing assembly is at the bottom-pushing starting position, and the bottle positioning assembly is in the bottle positioning position.

[0079] S2. Displacement data acquisition: Under the positioning of the bottle by the bottle mouth pushing assembly and the bottle positioning assembly, the driving surface of the bottom-pushing assembly moves from the bottom-pushing starting position to the bottom-pushing end position where it contacts the bottom surface of the bottle bottom; the detection assembly detects the moving distance value S of the driving surface of the bottom-pushing assembly moving from the bottom-pushing starting position to the bottom-pushing end position. Specifically:

[0080] Driven by the bottom-pushing driver 32, the push rod 38 continues to abut in the notch, and the bottle under inspection remains clamped between the bottle positioning assembly and the push rod 38; while the push block 31 slides relative to the push rod 38, so that the driving surface of the push block 31 continues to move forward until it contacts the bottom surface of the bottle bottom. When the driving surface of the push block 31 moves from the bottom-pushing starting position to the bottom-pushing end position, a moving distance value S is generated, and the sensor of the detection assembly detects the moving distance value S. As Figure 3 shown, at this time, the bottle mouth pushing assembly is still in the bottle mouth pushing position, the bottle positioning assembly is still in the bottle positioning position, and the bottom-pushing assembly is at the bottom-pushing end position.

[0081] S3. Direct inspection of the bottom depth value: By using the depth of the bottle bottom notch = L - S, the depth of the bottle bottom notch is obtained; thus, it is judged whether the depth value of the bottle bottom notch of the bottle under inspection meets the standard.

[0082] S4. Reset of each component; Repeat steps S1 to S3.

[0083] Embodiment 2 A device and method for detecting the depth of a bottle bottom

[0084] In order to meet the production needs in this embodiment, by using the fact that the moving distance value S of the bottom-pushing assembly is equal to the reset distance value B generated when it is reset, the moving distance value S is converted into the reset distance value B of the bottom-pushing assembly. By directly detecting the reset distance value B by the bottle bottom sensor 39, the bottom depth can be obtained. Therefore, on the basis of Embodiment 1, as Figures 2 to 3 shown, the detection assembly is added with the following technical features: a bottom-pushing reset part and a bottle bottom sensor 39.

[0085] The bottom-pushing reset part is used to generate a reset distance equal to the moving distance during the reset process of driving the bottom-pushing assembly. That is, the bottom-pushing reset part drives the bottom-pushing assembly to reset from the bottom-pushing end position to a position where the distance from the working end of the bottle-pushing assembly is L. The bottom-pushing reset part is fixedly installed on the power output end of the bottom-pushing assembly, on the side away from the bottle bottom. It moves with the bottom-pushing assembly to generate a moving distance, and generates a reset distance when it resets. The bottom-pushing reset part includes a bottle-pushing connecting plate 33 and a bottle-pushing bolt 34.

[0086] The bottle-pushing connecting plate 33 is movably connected to the power output end of the bottom-pushing assembly and is used to install the bottle-pushing assembly. The push rod 38 is fixedly installed at the bottom end of the bottle-pushing connecting plate 33. To improve the straightness of the movement of the bottle-pushing connecting plate 33, a connecting shaft 36 is fixedly installed at the top end of the bottle-pushing connecting plate 33, and the connecting shaft 36 is slidably connected in the linear bearing 37, and the linear bearing 37 is fixedly installed on the push block 31.

[0087] The bottle-pushing bolt 34 is used to move together with the bottom-pushing assembly. The tail end of the bottle-pushing bolt 34 passes through the bottle-pushing connecting plate 33 and is fixedly connected to the push block 31, and the bottle-pushing bolt 34 is slidably connected to the bottle-pushing connecting plate 33; a reset spring 35 is fixedly installed between the head end of the bottle-pushing bolt 34 and the bottle-pushing connecting plate 33. When the bottom-pushing assembly is at the bottom-pushing starting position, the reset spring 35 is in its original length; when the bottom-pushing assembly is at the bottom-pushing end position, the reset spring 35 is compressed.

[0088] The bottle bottom sensor 39 is fixedly installed on the frame and is used to detect the reset distance value B. In this embodiment, the bottle bottom sensor 39 detects the reset distance value B when the bottle-pushing connecting plate 33 resets from the bottom-pushing end position of the bottom-pushing assembly to a position where the distance from the working end of the bottle-pushing assembly is L. Of course, the bottle bottom sensor 39 can also detect the distance between the bottle-pushing bolt 34 from the bottom-pushing starting position to the bottom-pushing end position of the bottom-pushing assembly.

[0089] When using this embodiment under the control of the controller, the bottle bottom depth detection method includes the following steps:

[0090] S1. Starting position dynamic positioning

[0091] Same as S1. Starting position dynamic positioning in Embodiment 1. At this time, the reset spring 35 is in its original length state.

[0092] S2. Displacement data acquisition: Under the positioning of the bottle-pushing assembly and the bottle-fixing assembly for the bottle to be inspected, after the driving surface of the bottom-pushing assembly moves from the bottom-pushing starting position to the bottom-pushing end position in contact with the bottom surface of the bottle bottom, the bottom-pushing reset part drives the bottom-pushing assembly to reset, and a reset distance equal to the moving distance is generated during the reset process of the bottom-pushing assembly; the detection component detects the reset distance value B of the bottom-pushing assembly. Specifically:

[0093] S21. Generate moving distance: Driven by the bottom pushing driver 32, the push rod 38 continues to abut against the notch. The bottle to be inspected remains clamped between the bottle positioning assembly and the push rod 38, while the push block 31 drives the bottle pushing bolt 34 to continue moving forward until the driving surface of the push block 31 contacts the bottom surface of the bottle bottom. During the forward movement of the push block 31, the distance between the bottle pushing connecting plate 33 and the head end of the bottle pushing bolt 34 gradually decreases, and the return spring 35 is compressed until the return spring 35 is no longer further compressed when the driving surface of the push block 31 contacts the bottom surface of the bottle bottom, as Figure 3 shown. At this time, it is the positioning position of the bottom pushing reset part corresponding to the bottom pushing end position of the bottom pushing assembly;

[0094] S22. Generate return distance: While the bottom pushing driver 32 drives the bottom pushing assembly and the push port assembly to return, under the elastic force of the return spring 35, the bottom pushing reset part drives the bottom pushing assembly to return from the bottom pushing end position to a position where the distance from the working end of the push port assembly is L, and the bottle pushing connecting plate 33 generates a return distance value B equal to the moving distance value. The bottom sensor 39 detects the return distance value B generated when the bottle pushing connecting plate 33 returns from the bottom pushing end position to a position where the distance from the working end of the push port assembly is L.

[0095] S3. Direct inspection of the bottom depth value: Since the return distance value B of the bottom pushing assembly is equal to the moving distance value S of the bottom pushing assembly, the depth of the bottom notch of the bottle can be obtained as L - B, thereby determining whether the depth value of the bottom notch of the bottle to be inspected meets the standard.

[0096] S4. Reset each component. Repeat steps S1 to S3.

[0097] Embodiment 3 A device for detecting the bottom depth and the mouth diameter of a bottle

[0098] This embodiment can realize the detection of the bottom notch depth and the mouth diameter of the bottle to be inspected at the same detection position. Refer to Figure 1 shown. This embodiment includes a bottle positioning assembly fixedly installed on the frame for positioning the moving bottle and a bottle pushing assembly for pushing the bottle to be inspected to move. The structures and connection relationships of each part of the bottle positioning assembly and the bottle pushing assembly are as described in the bottle bottom depth detection device in Embodiments 1 to 2.

[0099] Based on Embodiments 1 and 2, this embodiment further introduces the structure of the bottle positioning assembly. The bottle positioning assembly includes a bottle top - pushing component.

[0100] The bottle top - pushing component is arranged corresponding to the mouth of the bottle to be inspected at the detection position for positioning the position of the bottle to be inspected moved by the bottle pushing assembly. The positioning position of the bottle top - pushing component for the bottle to be inspected corresponds one - to - one with the inner diameter of the bottle mouth, that is, for different inner diameters of the bottle mouth, their positioning positions on the bottle top - pushing component are different. According to the positioning position, the corresponding inner diameter size of the bottle mouth can be obtained. As Figure 6As shown in the figure, the top bottle assembly includes a top rod 7 fixedly installed on the frame body. A top head for extending into the bottle mouth is fixedly installed at the end of the top rod 7. The top head includes a first positioning portion 17, a second positioning portion 18, a qualified product positioning portion 19, and a third positioning portion 20 in sequence from the head end to the tail end.

[0101] The first positioning portion 17 is located at the head end of the top head and has a taper for positioning the moving bottle to be inspected.

[0102] The qualified product positioning portion 19 is used to indicate that the bottle to be inspected moving and positioned within this area is a qualified product, that is, this area corresponds to the inner diameter of the bottle mouth of the qualified bottle. The qualified product positioning portion 19 is a groove recessed relative to the second positioning portion 18 and the third positioning portion 20 for visually observing this area.

[0103] The contact surfaces of the second positioning portion 18 and the third positioning portion 20 with the inner surface of the bottle mouth are straight cylindrical surfaces, that is, the outer surfaces of the second positioning portion 18 and the third positioning portion 20 are straight cylindrical surfaces and do not have a taper.

[0104] When using this embodiment under the control of the controller, it includes the following steps:

[0105] S1. Dynamic positioning of the bottle body: Refer to the steps described in Embodiment 1 or Embodiment 2. When performing S12 to push the top of the bottle, during the process of the push rod 38 pushing the bottle to be inspected forward, the top head extends into the bottle mouth. When the first positioning portion 17 of the top head is stuck at a certain depth inside the bottle mouth, the bottle to be inspected is stuck and fixed between the top head and the push rod 38.

[0106] S2. Detection of the bottle mouth diameter: Observe the positioning position of the top of the bottle mouth on the top head. By the corresponding relationship between the positioning position of the bottle to be inspected by the pre-detected top bottle assembly and the diameter of the bottle to be inspected, obtain the inner diameter value of the bottle mouth corresponding to the positioning position of the bottle to be inspected, and then it can be judged whether the inner diameter of the bottle mouth meets the standard.

[0107] Or, directly observe whether the positioning position of the top of the bottle mouth is on the qualified product positioning portion 19 of the top head. If it is within this area, the inner diameter of the bottle mouth meets the standard; if it is not within this area, the inner diameter of the bottle mouth does not meet the standard.

[0108] S3. Detection of the bottom depth: Perform steps S2 to S3 in Embodiment 1; or perform steps S2 to S3 in Embodiment 2.

[0109] S4. Reset each component and repeat steps S1 to S3.

[0110] Embodiment 4 A device for detecting the bottom depth and the diameter of the bottle mouth

[0111] In order to improve production efficiency in this embodiment, the correspondence between the positioning position of the bottle-lifting assembly for the bottle to be inspected and the bottle mouth diameter is converted into the correspondence between the retraction distance value and the inner diameter of the bottle mouth. By detecting the retraction distance value, the inner diameter size of the bottle mouth can be obtained efficiently and accurately. And in order to improve the applicability of use, the position of the top head is adjusted through the up-and-down position adjustment assembly and the horizontal position adjustment assembly to ensure that the top head is coaxial with the bottle to be inspected at the detection position. Therefore, on the basis of Embodiment 3, this embodiment adds the following technical features: The bottle-fixing assembly further includes a retraction assembly 4, an up-and-down position adjustment assembly, and a horizontal position adjustment assembly. As Figures 4 to 5 shown, specifically as follows:

[0112] I. Retraction assembly 4

[0113] The driving surface of the retraction assembly 4 is arranged corresponding to the bottle mouth of the bottle to be inspected at the detection position, and is used to generate a retraction distance during the process of moving from contacting the bottle mouth of the bottle to be inspected to positioning the bottle. It is fixedly installed on the frame. The retraction positioning position of the retraction assembly 4 corresponds to the positioning position of the bottle-lifting assembly for the bottle to be inspected. The retraction assembly 4 includes a contact plate 8, a track 9, a track block 10, and a limit bolt 13:

[0114] The driving surface of the retraction assembly 4, that is, the contact surface of the contact plate 8 with the bottle mouth of the bottle to be inspected at the detection position. The contact plate 8 is fixedly installed on the track 9 and is two plate bodies symmetrically arranged relative to the bottle to be inspected at the detection position.

[0115] The track 9 is slidably connected inside the track block 10, and the track block 10 is fixedly installed on the up-and-down adjustment bracket 25; a connecting block 29 is fixedly installed outside the track block 10 at the rear end of the track 9, and a spring bracket 30 is fixedly installed at the front end of the track block 10. A spring 12 is fixedly installed between the connecting block 29 and the spring bracket 30, that is, a spring 12 for resetting the contact plate 8 is fixedly installed between the track block 10 and the track 9.

[0116] The limit bolt 13 is used to position the reset position of the contact plate 8 and is fixedly installed on the connecting block 29 of the track 9. The abutting position of the limit bolt 13 with the track block 10 corresponds to the reset position of the contact plate 8, that is, when the contact plate 8 is reset, the head of the limit bolt 13 abuts against the rear end of the track block 10.

[0117] In order to detect the retraction distance value of the retraction assembly 4, a bottle mouth sensor 2 is fixedly installed on the frame at the retraction positioning position corresponding to the retraction assembly 4. The bottle mouth sensor 2 is a laser sensor.

[0118] II. Horizontal position adjustment assembly

[0119] The horizontal position adjustment assembly is used to adjust the positioning position of the top rod 7 in the horizontal direction and is fixedly installed on the frame. The horizontal direction is the direction perpendicular to the axis of the bottle to be inspected on the horizontal plane. The horizontal position adjustment assembly includes an adjustment block 11, a horizontal knob 21, a horizontal adjustment bracket 22, and a horizontal adjustment hole 23.

[0120] The adjusting block 11 is fixedly connected to the rear end of the ejector rod 7, and the adjusting block 11 is slidably connected to the horizontal adjusting bracket 22. The adjusting block 11 can slide horizontally on the horizontal adjusting bracket 22.

[0121] The horizontal knob 21 is used to manually adjust the horizontal position of the adjusting block 11. The horizontal knob 21 is rotationally positioned with the horizontal adjusting bracket 22, that is, the horizontal knob 21 has a stepped optical axis section. This optical axis section passes through the horizontal adjusting bracket 22 and can rotate relative to the horizontal adjusting bracket 22, but the horizontal knob 21 is clamped on the horizontal adjusting bracket 22 and does not produce a horizontal displacement relative to the horizontal adjusting bracket 22. The threaded section at the rear end of the horizontal knob 21 is threadedly connected to the adjusting block 11.

[0122] The horizontal adjusting bracket 22 and the adjusting block 11 are provided with corresponding horizontal adjusting holes 23. The horizontal adjusting hole 23 on the horizontal adjusting bracket 22 is elongated, and the horizontal adjusting holes 23 on the adjusting block 11 are a plurality of through holes arranged at intervals. By passing a bolt through the corresponding horizontal adjusting holes 23 between the two, the position of the adjusting block 11 after sliding on the horizontal adjusting bracket 22 can be positioned.

[0123] III. Vertical position adjusting assembly

[0124] The vertical position adjusting assembly is used to adjust the vertical positioning position of the ejector rod 7 and is fixedly installed on the frame. The vertical position adjusting assembly includes a vertical knob 24, a vertical adjusting bracket 25, a connecting bracket 26, and a through hole 28.

[0125] The vertical knob 24 is used to manually adjust the vertical position of the adjusting block 11. The vertical knob 24 passes through the vertical adjusting bracket 25 located above the horizontal adjusting bracket 22. The vertical knob 24 is rotationally positioned with the vertical adjusting bracket 25, that is, the vertical knob 24 has a stepped optical axis section. This optical axis section passes through the vertical adjusting bracket 25 and can rotate relative to the vertical adjusting bracket 25, but the vertical knob 24 is clamped on the vertical adjusting bracket 25 and does not produce a vertical displacement relative to the vertical adjusting bracket 25. The threaded section at the bottom end of the vertical knob 24 is threadedly connected to the horizontal adjusting bracket 22.

[0126] The connecting bracket 26 is fixedly installed on the frame and is provided with a vertical adjusting hole 27, and the vertical adjusting hole 27 is an elongated hole. A plurality of through holes 28 arranged at intervals are provided on both the vertical adjusting bracket 25 and the horizontal adjusting bracket 22. The through holes 28 correspond to the vertical adjusting hole 27. By using bolts, the vertical positions of the vertical adjusting bracket 25 and the horizontal adjusting bracket 22 on the connecting bracket 26 can be positioned.

[0127] Before detecting the inner diameter of the bottle mouth, first adjust the position of the ejector rod 7 according to the size of the bottle to be inspected and the position of the inspection position to ensure that the top of the ejector rod 7 is coaxial with the bottle mouth.

[0128] When adjusting the horizontal positioning position of the ejector rod 7, rotate the horizontal knob 21. When the horizontal knob 21 drives the adjustment block 11 to slide along the horizontal adjustment bracket 22 to the horizontal positioning position of the ejector rod 7, position the adjustment block 11 on the horizontal adjustment bracket 22 by passing a bolt through the corresponding horizontal adjustment hole 23 between the horizontal adjustment bracket 22 and the adjustment block 11.

[0129] When adjusting the vertical positioning position of the ejector rod 7, rotate the up-and-down knob 24. When the up-and-down knob 24 drives the horizontal adjustment bracket 22 to move up and down to the positioning position, position the up-and-down positions of the up-and-down adjustment bracket 25 and the horizontal adjustment bracket 22 by passing a bolt through the corresponding up-and-down adjustment holes 27 between the horizontal adjustment bracket 22, the up-and-down adjustment bracket 25 and the adjustment block 11.

[0130] When using this embodiment under the control of the controller, it includes the following steps:

[0131] S1. Dynamic positioning of the bottle body: as described in Embodiment 3.

[0132] S2. Detection of the bottle mouth diameter

[0133] S21. Displacement data acquisition: During the process of the push rod 38 pushing the bottle to be inspected forward, starting from the bottle mouth moving to contacting the contact plate 8, under the thrust of the push rod 38, the contact plate 8 drives the track 9 to retract along the track block 10, and the spring 12 is compressed; until the top head positions the moving position of the bottle mouth, the contact plate 8 stops retracting. At this time, the retraction positioning position of the retraction assembly 4 corresponds to the positioning position of the bottle top assembly for the bottle to be inspected.

[0134] The bottle mouth sensor 2 detects the retraction distance value of the retraction assembly 4. The bottle mouth sensor 2 can collect the distance from the bottle mouth moving to contacting the contact plate 8 and driving the contact plate 8 to the retraction positioning position; the bottle mouth sensor 2 can also collect the distance between the contact plate 8 resetting from the retraction positioning position to the initial position of contacting the bottle mouth under the elastic force of the spring 12.

[0135] S22. Direct inspection of the bottle mouth diameter value: Obtain the inner diameter value of the bottle mouth corresponding to the retraction distance value of the bottle to be inspected through the corresponding relationship between the pre-detected retraction distance value and the diameter of the bottle to be inspected, and then it can be judged whether the inner diameter of the bottle mouth meets the standard.

[0136] S3. Bottom depth detection: Perform steps S2 to S3 in Embodiment 1; or perform steps S2 to S3 in Embodiment 2.

[0137] S4. Reset each component and repeat steps S1 to S3.
