Description

Technical Field

[0001] This invention relates to the field of controlled bottle detection technology, and in particular to a method and device for detecting the bottom of controlled bottles. Background Technology

[0002] In existing technology, there are specialized instruments for measuring the bottom wall thickness of controlled bottles. The specific measurement method involves first placing the controlled bottle onto the measuring rod of the instrument, ensuring the inner wall of the bottle's bottom is in contact with the rod. Then, the probe of the measuring instrument contacts the outer wall of the bottle's bottom. The instrument calculates the bottom thickness based on the readings of both the outer and inner walls. However, besides being unable to detect the unevenness or dents at the bottom, these existing controlled bottle inspection devices also have the following problems:

[0003] 1. Low detection efficiency: During the measurement process, the glass bottle needs to be placed on the bottom thickness measuring rod first, and then the probe needs to be used to contact the outer wall of the bottom of the bottle. After the measurement is completed, the glass bottle is removed from the bottom thickness measuring rod. In addition, before the measurement, it is necessary to adjust the bottom thickness measuring rod and the probe to be on the same axis to ensure the accuracy of subsequent measurements.

[0004] Second, the accuracy of the test is poor. Because the position of the bottom thickness measuring rod is limited by the size of the bottle mouth, when testing tubular bottles with small mouths and large bottoms, the bottom thickness measuring rod and the probe can only measure the points in the area corresponding to the bottle mouth on the bottom of the bottle, which leads to a small measurement range and increases the measurement error. Summary of the Invention

[0005] This invention discloses a method and device for detecting the bottom of a controlled bottle, which solves the problems of current controlled bottle detection equipment, which uses a detection structure that combines a bottom thickness measuring rod and a probe, resulting in complex detection steps, limited detection range, low efficiency and poor accuracy in detecting the bottom thickness, and inability to detect the concavity and convexity information of the bottle bottom.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a method for detecting the bottom of a controlled-flow bottle, comprising:

[0008] The control bottle is driven to rotate around its axis, and the rotating control bottle is controlled to move relative to the detection mechanism located on one side of the bottom of the control bottle, so that the detection mechanism forms multiple detection points in a spiral distribution on the bottom of the control bottle. The thickness and / or unevenness information of the bottom of the control bottle are then determined based on the distance between the multiple detection points and the detection mechanism.

[0009] Optionally, during the detection process where the control bottle and the detection mechanism move relative to each other, the bottom portion of the control bottle, which is controlled to rotate, passes through the detection area of ​​the detection mechanism, and the radial length of the bottom portion is greater than or equal to the radius of the bottom and less than the diameter of the bottom.

[0010] Optionally, during the detection process where the control bottle moves relative to the detection mechanism, the rotation speed of the control bottle is controlled according to the radius of the bottle bottom area passing through the detection mechanism, so that the distance between two adjacent detection points among the multiple detection points located at the bottom of the bottle is equal; as the radius of the multiple detection points located at the bottom of the bottle gradually decreases, the rotation speed of the control bottle gradually increases.

[0011] Secondly, based on the above-described method for detecting the bottom of controlled bottles, the present invention also provides a device for detecting the bottom of controlled bottles, the device comprising:

[0012] The testing mechanism is located on one side of the bottom of the controlled bottle and is used to form a testing point on the bottom of the controlled bottle;

[0013] A drive mechanism is used to drive the control bottle to rotate around its own axis;

[0014] A motion control mechanism, disposed in the drive mechanism or the detection mechanism, is used to control the relative movement between the rotating control bottle and the detection mechanism, so that the detection mechanism forms a plurality of detection points spirally distributed on the bottom of the rotating control bottle, and the detection mechanism determines the bottom thickness and / or concavity / convexity information of the control bottle based on the distances between the plurality of detection points and the detection mechanism.

[0015] Optionally, the driving mechanism includes a first clamping unit and a second clamping unit. The first clamping unit includes a rotation driving unit that drives the control bottle to rotate. The first clamping unit and the second clamping unit clamp the control bottle and drive the clamped control bottle to rotate around the axis of the control bottle under the action of the rotation driving unit.

[0016] Optionally, the movement control mechanism is disposed on the drive mechanism; the movement control mechanism includes a lifting module and a moving structure; in the first clamping unit and the second clamping unit, one is provided with the lifting module and the other is provided with the moving structure, and the first clamping unit and the second clamping unit control the clamped tube bottle to pass through the detection area of ​​the detection mechanism under the cooperation of the lifting module and the moving structure.

[0017] Optionally, the first clamping unit is a transmission belt mechanism; the transmission belt mechanism includes a base and a transmission belt, the base is provided with a driving wheel and at least one driven wheel, the transmission belt is sleeved on the driving wheel and the driven wheel, and cooperates with the second clamping unit to form a clamping area for clamping the control bottle, and the driving wheel serves as the rotation drive unit, the transmission belt runs under the action of the driving wheel and drives the control bottle in the clamping area to rotate around its own axis.

[0018] Optionally, the moving structure is an elastic telescopic structure, the driven wheel is connected to the base through the elastic telescopic structure, and the lifting module is disposed in the second clamping unit; during the process of the lifting module controlling the rise of the control bottle in the clamping area to push the transmission belt, the adaptive elastic deformation of the elastic telescopic structure causes the transmission belt to deform accordingly, so that the control bottle in the clamping area remains in contact with the transmission belt and moves through the detection area of ​​the detection mechanism.

[0019] Optionally, the control bottle bottom detection device further includes a limiting part, which is disposed on the bottle mouth side or bottle bottom side of the rotating control bottle. The direction of the force of the transmission belt for driving the control bottle to rotate is at an acute angle to the axis of the control bottle, so that the control bottle rotates and moves to the limiting part under the action of the transmission belt, thereby maintaining an effective detection distance between the bottom of the control bottle and the detection mechanism.

[0020] Alternatively, the bottle bottom detection device may further include a limiting part and an auxiliary mechanism. The limiting part and the auxiliary mechanism are respectively disposed on one side of the bottle mouth and one side of the bottle bottom of the rotating control bottle. The rotating control bottle moves to the limiting part under the action of the auxiliary mechanism to maintain an effective detection distance between the bottom of the control bottle and the detection mechanism.

[0021] Optionally, the driving mechanism includes a rotary driving unit and a clamping mechanism, the clamping mechanism being disposed on the rotary driving unit, and the rotary driving unit being disposed on the movement control mechanism; the rotary driving unit drives the clamping mechanism to rotate, and controls the clamped tube bottle to rotate around its own axis through the rotation of the clamping mechanism, and the movement control mechanism controls the rotating tube bottle to pass through the detection area of ​​the detection mechanism.

[0022] The technical solution adopted in this invention can achieve the following beneficial effects:

[0023] The present invention discloses a method and device for detecting the bottom of a controlled bottle. By driving the controlled bottle to rotate around its axis and controlling the relative movement between the rotating controlled bottle and a detection mechanism located on one side of the bottom of the controlled bottle, the detection mechanism forms multiple detection points spirally distributed on the bottom of the rotating controlled bottle. The thickness and / or concavity / convexity information of the bottom of the controlled bottle are determined based on the distances between the multiple detection points and the detection mechanism. This method solves the problems of current controlled bottle detection equipment, which uses a detection structure that combines a bottom thickness measuring rod and a probe, resulting in complex detection steps, limited detection range, low efficiency and poor accuracy in bottom thickness detection, and inability to detect bottom concavity / convexity information.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] This invention discloses a method for detecting the bottom of a controlled bottle, comprising: driving the controlled bottle to rotate around its axis, and controlling the rotating controlled bottle to move relative to a detection mechanism disposed on one side of the bottom of the controlled bottle, so that the detection mechanism forms a plurality of detection points spirally distributed on the bottom of the controlled bottle, and then determining the thickness and / or unevenness information of the bottom of the controlled bottle based on the distance between the plurality of detection points and the detection mechanism.

[0041] This method allows testing agencies to inspect the bottom of controlled bottles in a non-contact manner. Compared to existing methods for inspecting the bottom of controlled bottles, it avoids the need for a bottom thickness measuring rod and probe to perform contact inspections, making the inspection of the bottom of controlled bottles convenient, fast, efficient, and accurate. It can also meet the requirements for inspecting the concavity and convexity information of the bottom of controlled bottles. Typically, testing agencies can choose non-contact displacement sensors such as laser displacement sensors, spectral confocal displacement sensors, capacitive displacement sensors, and ultrasonic displacement sensors.

[0042] Furthermore, since the control bottle will also move relative to the detection mechanism during its rotation around its own axis, the detection points of the detection mechanism will be spirally distributed at the bottom of the control bottle (i.e., the relative motion between the rotating control bottle and the detection mechanism is continuous), or the detection points of the detection mechanism will be concentrically distributed at the bottom of the control bottle (i.e., the relative motion between the rotating control bottle and the detection mechanism is intermittent).

[0043] Therefore, compared to the situation where the detection points of the detection mechanism are distributed in parallel lines or zigzag lines at intervals, resulting in some of the signals emitted by the detection mechanism during the detection process being outside the bottom area of ​​the controlled bottle and becoming useless signals, the detection points of the detection mechanism in this embodiment are distributed in a spiral pattern, which ensures that the signals emitted by the detection mechanism during the detection process are basically located within the bottom area of ​​the controlled bottle, thereby improving the bottom detection efficiency.

[0044] Specifically, the testing agency selects a spectral confocal displacement sensor. During testing, the spectral confocal displacement sensor emits a light beam to multiple points on the bottom of the controlled bottle. The emitted light beam is reflected on the inner and outer surfaces of the bottom of the controlled bottle and received by the spectral confocal displacement sensor. The spectral confocal displacement sensor determines the distance S1 between the outer surface of the bottom of the controlled bottle and the spectral confocal displacement sensor based on the reflected light received from the outer surface of the bottom of the controlled bottle. The spectral confocal displacement sensor determines the distance S2 between the inner surface of the bottom of the controlled bottle and the spectral confocal displacement sensor based on the reflected light received from the inner surface of the bottom of the controlled bottle. Then, the thickness of the bottom of the controlled bottle at that point is determined based on the distance difference ΔS(S2-S1) between the inner and outer surfaces.

[0045] Then, the spectral confocal displacement sensor can determine the unevenness information of the outer surface of the bottom of the control bottle based on the distance S1 of multiple points detected at the bottom of the control bottle, the unevenness information of the inner surface of the bottom of the control bottle based on the distance S2 of multiple points detected at the bottom of the control bottle, and the thickness information of the bottom of the control bottle based on the distance difference ΔS of multiple points detected at the bottom of the control bottle.

[0046] It is understandable that when the testing frequency of the testing agency is relatively high, there will be overlapping parts between the multiple testing points formed by the testing agency on the bottom of the control bottle, thus forming a spiral testing curve on the bottom of the control bottle. The thickness of the bottom of the control bottle determined by this testing curve can also be reflected in the form of a line.

[0047] Meanwhile, the relative movement between the rotating control bottle and the detection mechanism can be vertical, horizontal, or oblique. Specifically, during the relative movement, the position of the detection mechanism can be fixed, and the rotating control bottle can be controlled to move through the detection area of ​​the detection mechanism to complete the detection of the bottle bottom. Alternatively, the position of the rotating control bottle can be fixed, that is, the control bottle rotates around its own axis at a fixed position, and the detection mechanism can be controlled to move through the bottom area of ​​the control bottle to complete the detection of the bottle bottom. Alternatively, the rotating control bottle and the detection mechanism can be controlled to move separately to complete the detection of the bottle bottom. This embodiment does not limit the relative movement mode of the rotating control bottle and the detection mechanism.

[0048] However, since the detection mechanism usually has power cords, data cables and other connecting lines, controlling the movement of the detection mechanism is not only inconvenient, but also easily affects the connecting lines. For example, if the spectral confocal displacement sensor moves continuously, the optical fiber connected to it may break. Therefore, in order to improve the stability and accuracy of the bottom detection of the control bottle, it is preferable to fix the position of the detection mechanism and control the movement of the rotating control bottle to pass through the detection area of ​​the detection mechanism, so that the detection mechanism forms multiple detection points spirally distributed on the bottom of the rotating control bottle.

[0049] In addition, testing agencies have an effective testing range. If the distance between the bottom of the controlled bottle and the testing agency is too far or too close, it will affect the test results. Therefore, during the testing process, it is necessary to control the distance between the bottom of the controlled bottle and the testing agency so that the distance is within the effective testing range of the testing agency. Especially when testing the concavity and convexity information of the bottom of the controlled bottle, since the concavity and convexity information of the inner or outer surface of the bottom of the controlled bottle is determined based on the distance between each testing point on the inner or outer surface of the bottom of the controlled bottle and the testing agency, it is necessary to keep the distance between the bottom of the controlled bottle and the testing agency constant during the testing process to ensure the accuracy of the test results of the concavity and convexity information of the inner or outer surface of the bottom of the controlled bottle.

[0050] In particular, during the detection process where the controlled bottle moves relative to the detection mechanism, the bottom portion of the controlled bottle, which is controlled to rotate, passes through the detection area of ​​the detection mechanism. The radial length of the bottom portion is greater than or equal to the radius of the bottom and less than the diameter of the bottom. This allows the bottom of the controlled bottle to be fully detected by the detection mechanism without having to completely pass through its detection area, thus saving detection time and improving detection efficiency.

[0051] To ensure the accuracy of the test results, during the test process where the control bottle moves relative to the testing mechanism, the rotation speed of the control bottle can be controlled according to the radius of the bottle bottom area passing through the testing mechanism, so that the distance between two adjacent testing points among the multiple testing points located at the bottom of the control bottle is equal; as the radius of the multiple testing points located at the bottom of the bottle gradually decreases, the rotation speed of the control bottle gradually increases.

[0052] It is understandable that when the distance between the detection points is small, that is, when the difference in the radius of the detection points at the bottom of the bottle is small, the rotation speed of the control bottle will not change significantly. However, when the difference in the radius of the detection points at the bottom of the bottle is large, the rotation speed of the control bottle will change more significantly.

[0053] Example 2

[0054] Based on the method for detecting the bottom of controlled bottles in Embodiment 1, this embodiment discloses a device for detecting the bottom of controlled bottles, which includes:

[0055] The testing facility is located on one side of the bottom of the controlled bottle to create a testing point on the bottom of the controlled bottle;

[0056] The drive mechanism is used to drive the control bottle to rotate around its own axis;

[0057] A motion control mechanism, located in the drive mechanism or detection mechanism, is used to control the relative movement of the rotating control bottle and the detection mechanism, so that the detection mechanism forms multiple detection points spirally distributed on the bottom of the rotating control bottle, and the detection mechanism determines the bottom thickness and / or concavity / convexity information of the control bottle based on the distances between the multiple detection points and the detection mechanism.

[0058] The driving mechanism may include a first clamping unit and a second clamping unit. The first clamping unit and the second clamping unit may be a left-right opening and closing clamping structure or a right-up opening and closing clamping structure. The first clamping unit includes a rotation driving unit that drives the control bottle to rotate. The first clamping unit and the second clamping unit clamp the control bottle and drive the clamped control bottle to rotate around its own axis under the action of the rotation driving unit.

[0059] As one specific implementation method, such as Figure 1As shown, the first clamping unit 100 may include a rotary drive unit 101 for driving the control bottle 103 to rotate and an auxiliary wheel 201. The second clamping mechanism includes two auxiliary wheels 201. The first clamping unit 100 and the second clamping unit 200 clamp the control bottle 103 through the corresponding auxiliary wheels 201. The control bottle 103 rotates under the rotary drive of the rotary drive unit 101. Through the structural design of the auxiliary wheels 201, the sliding friction between the control bottle 103 and the first clamping unit 100 and the second clamping unit 201 during rotation is avoided, thus preventing damage to the control bottle 103. The rotary drive unit 101 may be an active wheel connected to a drive mechanism such as a motor.

[0060] It is understood that one or more of the auxiliary wheels 201 can also be connected to a drive mechanism such as a motor, so that the auxiliary wheels 201 can play the role of driving rotation like the rotary drive unit 101. The number of driven wheels 102 and auxiliary wheels 201 in this embodiment is only an example. In actual applications, the number of driven wheels 102 and auxiliary wheels 201 can be increased or decreased as needed. This embodiment does not impose any limitations on this.

[0061] As another specific implementation method, such as Figure 2 As shown, the first clamping unit 100 includes a rotary drive unit 101 for driving the control bottle 103 to rotate and a driven wheel 102. The second clamping mechanism includes two auxiliary wheels 201. The first clamping unit 100 and the second clamping unit 200 clamp the control bottle 103 through the driven wheel 102 and the auxiliary wheel 201. The rotary drive unit 101 drives the driven wheel 102 to rotate through its own rotation. The driven wheel 102 then drives the control bottle 103 to rotate around its own axis. The auxiliary wheel 201 cooperates with the driven wheel 102 to assist in rotation. The rotary drive unit 101 is a drive wheel connected to a motor or other drive mechanism.

[0062] Of course, one or more of the auxiliary wheels 201 can also be connected to a drive mechanism such as a motor, so that the rotation of the auxiliary wheels 201 drives the control bottle 103 to rotate around its own axis; or, the driven wheel 102 can be removed, and the rotation drive unit 101 can directly cooperate with the auxiliary wheel 201, which can both clamp the control bottle 103 and drive the rotation of the control bottle 103; at the same time, the specific number of driven wheels 102 and auxiliary wheels 201 in this embodiment is only an example. In actual applications, the number of driven wheels 102 and auxiliary wheels 201 can be increased or decreased according to the situation. For example, the number of driven wheels 102 can be 2 or 3, and the number of auxiliary wheels 201 can be 3 or 4, etc. This embodiment does not limit this.

[0063] As another specific implementation method, such as Figure 3 and Figure 4As shown, the first clamping unit 100 is a transmission belt mechanism, which includes a base 120 and a transmission belt 110. The base 120 is provided with a driving wheel and at least one driven wheel 102. The transmission belt 110 is sleeved on the driving wheel and the driven wheel 102, and cooperates with the second clamping unit 200 to form a clamping area for clamping the control bottle 103. The driving wheel, as a rotation drive unit 101, drives the transmission belt 110 to run. While running, the transmission belt 110 drives the control bottle 103 in the clamping area to rotate around its own axis.

[0064] In this embodiment, to prevent damage to the connection lines of the detection mechanism caused by moving the detection mechanism, the movement control mechanism can be set in the drive mechanism, and the specific setting method is as follows:

[0065] When the drive mechanism is as follows Figure 1 In the structure shown, the movement control mechanism is a lifting module. The first clamping unit 100 and the second clamping unit 200 are both located in the lifting module. When the first clamping unit 100 and the second clamping unit 200 clamp the tubular bottle 103 and drive the tubular bottle 103 to rotate via the rotation drive unit 101, the lifting module controls the first clamping unit 100 and the second clamping unit 200 to lift and lower simultaneously, so that the clamped tubular bottle 103 passes through the detection area of ​​the detection mechanism and completes the detection of the bottom of the bottle.

[0066] When the drive mechanism is as follows Figure 2 or Figure 3 In the structure shown, the motion control mechanism may include a lifting module and a moving structure. One of the first clamping unit 100 and the second clamping unit 200 is provided with a lifting module, and the other is provided with a moving structure.

[0067] For example, when the first clamping unit 100 is equipped with a moving structure and the second clamping unit 200 is equipped with a lifting module, the lifting module controls the second clamping unit 200 to rise so that the control bottle 103 located in the second clamping unit 200 rises and contacts the first clamping unit 100. After the control bottle 103 contacts the first clamping unit 100, the first clamping unit 100 and the second clamping unit 200 form a clamping area for clamping the control bottle 103 and drive the control bottle 103 to rotate. Then, as the lifting module continues to control the second clamping unit 200 to rise, the control bottle 103 located in the clamping area also continues to rise and pushes the first clamping unit 100 upward. At the same time, the first clamping mechanism 100 rises together with the control bottle 103 under the adaptive action of the moving mechanism, so that the control bottle 103 in the clamping area rotates through the detection area of ​​the detection mechanism 400 to complete the detection of the bottle bottom.

[0068] Alternatively, when the first clamping unit 100 is equipped with a lifting module and the second clamping unit 200 is equipped with a moving structure, the lifting module controls the first clamping unit 100 to move downwards. After the first clamping unit 100 contacts the control bottle 103 located in the second clamping unit 200, the first clamping unit 100 and the second clamping unit 200 form a clamping area to clamp the control bottle 103 and drive the control bottle 103 to rotate. Then, as the lifting module continues to control the first clamping unit 100 to descend, the first clamping unit 100 presses the control bottle 103 downwards in the clamping area. At the same time, the control bottle 103 presses the second clamping unit 200 downwards, so that the second clamping unit 200 moves downwards along with the control bottle 103 under the adaptive action of the moving mechanism, so that the control bottle 103 in the clamping area rotates through the detection area of ​​the detection mechanism 400 to complete the detection of the bottle bottom.

[0069] When the drive mechanism is as follows Figure 3 In the structure shown, as another possible implementation, the movement control mechanism may only include a lifting module, and the lifting module is disposed in the second clamping unit 200. The transmission belt 110 in the first clamping unit 100 is selected from structural components with good elasticity, such as rubber belts or elastic bands. The lifting module controls the tube bottle 103 located in the second clamping unit 200 to rise and push the transmission belt 110, and under the adaptive elastic deformation of the transmission belt 110, the rotating tube bottle 103 moves upward through the detection area of ​​the detection mechanism 400.

[0070] Compared to not designing a moving structure, the design of a moving structure allows the transmission belt 110 to use non-elastic or less elastic structural components, thereby improving the structural strength of the transmission belt 110 and reducing the wear of the transmission belt 110 caused by the rotation of the control bottle 103. Compared to structural components with better elasticity such as rubber belts or elastic bands, this significantly extends the service life of the transmission belt 110, especially when the control bottle 103 rotates at a high speed during the testing process.

[0071] In this embodiment, the disclosed moving structure can be an elastically telescopic structure, such as... Figures 3 to 6 As shown, the second clamping unit 200 is equipped with a lifting module 140, and the driven wheel 102 in the first clamping unit 100 is connected to the base 120 through an elastic telescopic structure 130. During the process of the lifting module 140 controlling the rise of the control bottle 103 in the clamping area to push the transmission belt 110, the elastic telescopic structure 130 adapts to the elastic deformation, causing the transmission belt 110 to deform accordingly, so that the rotating control bottle 103 rises and moves through the detection area of ​​the detection mechanism 400.

[0072] Of course, the elastic telescopic structure 130 can also be set on the base 120. During the process of the lifting module 140 controlling the rise of the control bottle 103 in the clamping area to push the transmission belt 110, the elastic telescopic structure 130 adapts to elastic deformation, so that the first clamping unit 100 rises together with the lifting module 140, thereby enabling the rotating control bottle 103 to rise through the detection area of ​​the detection mechanism 400 and complete the detection of the bottom of the bottle.

[0073] It is easy to understand that the moving structure can be a hydraulic rod, an electric rod, or a rack and pinion type that requires a power source for control, or it can be an elastic telescopic structure that does not require a power source, such as a spring or a spring sheet. Preferably, the moving structure is an elastic telescopic structure 130, which has better adaptability than hydraulic rods, electric rods, or rack and pinion types and does not require a power source.

[0074] In this embodiment, the disclosed bottle bottom detection device may further include a limiting part 300, such as... Figures 5 to 7 As shown, the limiting part 300 is disposed on one side of the bottle mouth or the bottom side of the rotating control bottle 103, and the setting direction of the transmission belt 110 is at an acute angle to the axial direction of the control bottle 103 (that is, the setting direction of the transmission belt 110 is oblique to the axial direction of the control bottle 103). When the transmission belt 110 contacts the control bottle 103 to be tested, the transmission belt 110, under the driving action of the rotation drive unit 101, can not only drive the control bottle 103 to rotate around its axis, but also apply a component force in the axial direction of the control bottle 103, so that the control bottle 103 rotates and moves to the limiting part 300, thereby ensuring that the distance between the bottom of the control bottle 103 and the detection mechanism 400 remains constant during the detection process, and completing the determination of the concave and convex information of the bottom of the control bottle 103.

[0075] Alternatively, the bottle bottom detection device disclosed in this embodiment may also include a limiting part 300 and an auxiliary mechanism. The limiting part 300 and the auxiliary mechanism are respectively disposed on the bottle mouth side and the bottle bottom side of the control bottle 103. The rotating control bottle 103 moves to the limiting part 300 under the action of the auxiliary mechanism, so that the distance between the bottom of the control bottle 103 and the detection sensor remains constant.

[0076] The auxiliary mechanism can be a fan structure, which can use wind power to blow the rotating control bottle 103 toward the limiting part 300 without contacting the control bottle 103; or, the auxiliary mechanism can be a push rod or push plate structure, which can push the rotating control bottle 103 toward the limiting part 300 through the pushing force of the push rod or push plate.

[0077] Preferably, the method for detecting the bottom of the controlled bottle described in Example 1 is applied to... Figure 2 or Figure 4When the device is in use, during the descent process after the lifting detection of the control bottle 103, the rotary drive unit 101 stops rotating or slows down its rotation speed so that the control bottle 103 disengages from the driven wheel 102. Figure 2 (as shown) or when disengaged from the drive belt 110 ( Figure 4 As shown), it will not be carried away by the rapidly rotating driven wheel 102 or the transmission belt 110.

[0078] Example 3

[0079] This embodiment modifies the drive mechanism in the above embodiments, such as... Figure 8 and Figure 9 As shown, in the bottle bottom detection device disclosed in this embodiment, the driving mechanism may include a rotary driving unit 101 and a clamping mechanism 500. The clamping mechanism 500 is disposed on the rotary driving unit 101 and rotates under the drive of the rotary driving unit 101. The rotation axis of the clamping mechanism 500 and the axis of the control bottle it clamps are located on the same straight line. Therefore, when the rotary driving unit 101 drives the clamping mechanism 500 to rotate, the control bottle will rotate around its axis under the rotation control of the clamping mechanism 500.

[0080] The rotary drive unit is located in the motion control mechanism, which can be the lifting module 140. The lifting module 140 controls the rotary drive unit 101 and the clamping mechanism 500 located in the rotary drive unit 101 to rise simultaneously, so that the clamping mechanism 500 clamps and drives the rotating tubular bottle to rise through the detection area of ​​the detection mechanism 400 to complete the detection of the bottom of the bottle.

[0081] Specifically, when the conveyor line transports the control bottle to the position of the lifting mechanism 160, the lifting mechanism 160 moves upward and lifts the control bottle to a height that can be clamped by the clamping mechanism 500. At this time, the clamping mechanism 500 clamps the control bottle. After the clamping mechanism 500 clamps the control bottle, the lifting module 140 controls the rotary drive unit 101 and the clamping mechanism 500 to rise. The rotary drive unit 101 drives the clamping mechanism 500 to rotate, so that the control bottle rotates around its own axis and rises to pass through the detection area of ​​the detection mechanism 400 to complete the detection of the bottle bottom. After the bottle bottom detection is completed, the lifting module 140 controls the rotary drive unit 101 and the clamping mechanism 500 set on the rotary drive unit 101 to descend. The clamping mechanism 500 places the detected control bottle back onto the lifting mechanism 160, and the lifting mechanism 160 then drives the control bottle to descend and return to the conveyor line.

[0082] The lifting mechanism 160 is equipped with a groove structure and an air intake 161. During the process of the lifting mechanism 160 lifting the control bottle upward, the air intake 161 applies suction to the control bottle, so that the control bottle can remain stable during the upward process. When the lifting mechanism 160 stops lifting the control bottle, the suction applied to the control bottle by the air intake 161 not only prevents the control bottle from continuing to move upward due to inertia and eventually falling off the lifting mechanism 160, but also prevents the control bottle from continuing to move upward due to inertia and eventually falling back to a position closer to the detection mechanism of the lifting mechanism 160, thus preventing the clamping mechanism 500 from clamping the control bottle.

[0083] Of course, a fan structure or a pressing structure can also be installed above the lifting mechanism 160. The fan structure or pressing structure works in conjunction with the lifting mechanism 160 to allow the lifting mechanism 160 to smoothly lift the control bottle to a height that can be clamped by the clamping mechanism 500.

[0084] Meanwhile, a pad 151 is provided on the inner side of the clamping mechanism 500 to prevent damage to the control bottle when clamping it. It can also increase the friction between the clamping mechanism 500 and the control bottle, and prevent the control bottle from falling off during the process of the rotation drive unit 101 driving the clamping mechanism 500 to rotate while clamping the control bottle. The pad 151 can be made of materials such as polytetrafluoroethylene or rubber.

[0085] In Embodiments 2 and 3 of this application, the passage of the controlled bottle through the detection area of ​​the detection agency, the passage of the bottom of the controlled bottle through the detection area of ​​the detection agency, or the passage of the bottom of the bottle through the detection area of ​​the detection agency can be a complete passage or a partial passage.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0087] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
