At the same time, the method is easy to operate and easy to use.
[0032] Embodiment 1
[0033] The following is a detailed description of a detection device for protrusions on the inner wall surface of a wine bottle mouth provided by this embodiment in conjunction with the accompanying drawings. Figure 1 As shown, it includes: a base 1, a column 3, a support plate 4, an operating rod 5 and a detection plunger 6. The base 1 is used for placing a wine bottle 2 to be detected. The lower end of the column 3 is arranged on the base 1, and the upper end of the column 3 is installed with the support plate 4. The support plate 4 is arranged horizontally and parallel to the base 1; the operating rod 5 is arranged vertically, and the operating rod 5 is arranged on the support plate 4, and the operating rod 5 can move vertically freely; the detection plunger 6 is arranged at the lower end of the operating rod 5 and keeps coaxiality with the wine bottle 2 to be detected. The detection plunger 6 extends into the bottle mouth of the wine bottle 2 to be detected under the movement of the operating rod 5 to closely contact the inner wall of the bottle mouth, wherein the detection plunger 6 can sense the pressure value change when it is in close contact with the surface protrusion of the inner wall of the bottle mouth of the wine bottle 2 to be detected, and judge whether there is a surface protrusion according to the pressure value change.
[0034] In this embodiment, when it is necessary to detect the protrusion on the inner wall surface of the bottle mouth of the wine bottle 2 to be detected, the wine bottle 2 to be detected is fixed on the base 1, and the detection plunger 6 is extended into the bottle mouth of the wine bottle 2 to be detected through the operating rod 5, and is in close contact with the inner wall surface of the bottle mouth. According to the principle that the pressure of the protrusion on the inner wall of the bottle mouth and the pressure of the smooth inner wall surface show different values, the protrusion on the inner wall surface of the bottle mouth is sensed by the detection plunger 6, and then rapid detection can be achieved with high accuracy, and it is not easy to cause missed detection or false detection, and the quality of the product can be guaranteed.
[0035] Please continue to refer to Figure 1 As shown, in this embodiment, it should be noted that a through hole 41 is provided in the middle of the support plate 4, the through hole 41 passes through the upper and lower surfaces of the support plate 4, the operating rod 5 is sleeved in the through hole 41, and can move vertically freely in the through hole 41.
[0036] In some embodiments, the through hole 41 can be set to a circular, square, elliptical or other irregular shapes. In this embodiment, a circular shape is used as an example for explanation. The operating rod 5 is adapted to the circular through hole 41, and the operating rod 5 extends into the through hole 41, and the outer peripheral wall of the operating rod 5 is kept in contact with the inner peripheral wall of the through hole 41 to ensure that the operating rod 5 can move freely up and down in the through hole 41. Of course, when moving, the operating rod 5 can be manually operated or with the help of other electric tools, such as using a cylinder to drive the operating rod 5 to move up and down in the through hole 41. The specific method is not specifically limited in this embodiment.
[0037] In this embodiment, it should also be noted that a placement groove 11 is provided on the base 1 , the placement groove 11 is adapted to the wine bottle 2 to be detected, and the placement groove 11 is arranged directly below the through hole 41 .
[0038] In some embodiments, a placement groove 11 is provided on the upper surface of the base 1, and the placement groove 11 is for the bottom end of the wine bottle 2 to be tested to be placed, and the placement groove 11 is set at a position directly below the through hole 41, so that when the bottom end of the wine bottle 2 to be tested is placed in the placement groove 11, the top end just corresponds to the operating rod 5 in the through hole 41, and then the operating rod 5 is moved vertically downward, so that the detection plunger 6 can be just inserted into the bottle mouth of the wine bottle 2 to be tested, which reduces the centering time and facilitates detection. Among them, the placement groove 11 can be set to be circular, which is compatible with the shape of the wine bottle 2 to be tested, and of course it can also be set to be rectangular. The bottom of the wine bottle 2 to be tested is stuck in the placement groove 11, and it is not easy to rotate. During the detection, the position of the wine bottle 2 to be tested can be kept fixed, so that the detection plunger 6 can be accurately inserted into the bottle mouth of the wine bottle 2 to be tested from top to bottom for detection.
[0039] In this embodiment, it should also be noted that a disc 7 is provided at the lower end of the operating rod 5, the disc 7 is arranged horizontally, and the detection plunger 6 is arranged on the side of the disc 7 away from the operating rod 5, and the operating rod 5, the disc 7 and the detection plunger 6 are arranged coaxially.
[0040] In some embodiments, the lower end area of the operating rod 5 is limited. In order to facilitate the installation of the detection plunger 6, a disc 7 is installed at the lower end of the operating rod 5. The surface area of the disc 7 is larger than the lower end surface of the operating rod 5. In this way, the detection plunger 6 can be conveniently set on the side of the disc 7 away from the operating rod 5. Of course, the disc 7 can also play a role in shielding dust, preventing dust from falling directly on the detection plunger 6 during the placement process.
[0041] In this embodiment, it should also be noted that the detection plunger 6 is configured to be cylindrical and is adapted to the bottle mouth of the wine bottle 2 to be detected.
[0042] In some embodiments, the mouth of the wine bottle 2 to be inspected is cylindrical in shape. In order to make the detection more accurate, the detection plunger 6 is set to be a cylinder, and the plunger diameter can be determined according to the inner diameter of the bottle mouth, so that it can better adapt to the mouth of the wine bottle 2 to be inspected, and can be in close contact with the inner wall when extended into the bottle mouth.
[0043] In this embodiment, it should also be noted that the detection plunger 6 includes a plunger body and a pressure-sensitive membrane. The plunger body has a certain elasticity and can be elastically deformed under the extrusion of an external force. The material can be rubber. The pressure-sensitive membrane is attached to the outer peripheral surface of the plunger body. The output signal end of the pressure-sensitive membrane is electrically connected to the input port of the controller, such as by wire connection. The pressure-sensitive membrane is used to closely contact the inner wall of the bottle mouth to sense whether there is a surface protrusion on the bottle mouth, and transmit the detection result to the controller. The controller can communicate with the display device through Bluetooth or other methods, and the controller transmits the detection result to the display device for display.
[0044] In some embodiments, a pressure sensitive film is attached to the outer peripheral surface of the plunger body. When the detection plunger 6 is extended into the inner wall of the bottle mouth and in close contact, the raised area will squeeze the pressure sensitive film, and the pressure sensitive film will feel the pressure change and transmit the pressure change value to the controller. Then, it can be judged whether there is a surface protrusion based on the pressure change value.
[0045] Among them, the pressure sensitive film can be a resistive pressure sensitive film or a capacitive pressure sensitive film. The resistive pressure sensitive film is controlled by pressure sensing and is mainly divided into two types: four-wire and five-wire. The basic structure of its pressure sensitive film usually includes three parts: two transparent resistive conductor layers, an isolation layer between the two conductor layers, and electrodes. The resistive conductor layer is made of resistive materials, such as indium tin oxide (ITO) coated on a substrate. The upper substrate can be a plastic layer with a hardened outer surface and smooth and scratch-resistant (i.e., the surface layer of the pressure sensitive film), and the lower substrate can be a glass or hard plastic flat plate (i.e., as a base layer). The isolation layer is a viscous insulating liquid material, such as polyester film. The electrode is made of materials with excellent conductive properties, such as silver powder ink and copper foil.
[0046] The basic structure of the capacitive pressure sensitive film is roughly the same as that of the resistive pressure sensitive film, except that the resistive conductor layer is made of capacitive material.
[0047] How to select the pressure sensitive film is not specifically limited in this embodiment.
[0048] Please refer to Figure 1 , Figure 2 As shown, in this embodiment, a method for detecting protrusions on the inner wall surface of the mouth of a wine bottle is also provided, and detection is performed using the above-mentioned device for detecting protrusions on the inner wall surface of the mouth of a wine bottle.
[0049] In this embodiment, it should be noted that the detection method includes the following steps:
[0050] S1, fix the wine bottle 2 to be tested on the base 1;
[0051] In this embodiment, it should be noted that the wine bottle 2 to be detected is fixed in the placement groove 11 on the upper surface of the base 1, and the position of the wine bottle 2 to be detected is fixed by the placement groove 11.
[0052] S2. During the inspection, the operating rod 5 is operated to extend the inspection plunger 6 into the mouth of the wine bottle 2 to be inspected until it is in close contact with the inner wall of the mouth of the wine bottle 2 to perform a surface protrusion inspection on the inner wall of the mouth of the wine bottle 2 to be inspected;
[0053] In the present embodiment, it should be noted that, during detection, the operating rod 5 is operated to move the operating rod 5 downward with the detection plunger 6, and the detection plunger 6 is extended into the bottle mouth of the wine bottle 2 to be detected until it is in close contact with the inner wall of the bottle mouth. At this time, the pressure of the inner wall of the bottle mouth is sensed by the pressure sensitive membrane of the detection plunger 6, and the presence of a surface protrusion is determined based on the value of the pressure change detected by the detection plunger 6; wherein, the pressure of the protrusion on the inner wall of the bottle mouth is different from the value displayed by the pressure of the smooth inner wall surface.
[0054] S3. If the test result is normal, the bottle mouth of the wine bottle 2 to be tested is tested normally, and the normal wine bottle enters the next process; otherwise, the bottle mouth of the wine bottle 2 to be tested is tested abnormally, and the wine bottle with a bulge on the inner wall surface of the bottle mouth is removed.
[0055] In the present embodiment, it should be noted that an electrical connection is formed between the output signal end of the pressure sensitive membrane and the input port of the controller. The pressure sensitive membrane is in close contact with the inner wall surface of the bottle mouth when in use, and then senses the inner wall of the bottle mouth through the pressure sensitive membrane. When the contact surface of the pressure sensitive membrane senses a change in pressure value, the signal is transmitted to the controller, and the controller controls the corresponding display to display the pressure change, and then determines whether there is a protrusion on the inner wall surface of the bottle mouth of the wine bottle 2 to be detected based on the pressure change.
[0056] Specifically, if the pressure change of the inner wall pressure of the mouth of the wine bottle 2 to be detected detected by the pressure sensitive membrane is within the preset limit, it means that the mouth detection of the wine bottle 2 to be detected is normal, and the normal wine bottle enters the next process; if the pressure change of the inner wall pressure of the mouth of the wine bottle 2 to be detected detected by the pressure sensitive membrane exceeds the preset limit or the pressure is uneven, it means that the mouth detection of the wine bottle 2 to be detected is abnormal, and the rejector will remove the abnormal wine bottle. Among them, the preset limit can be set according to the actual situation, and there is no specific limitation in this embodiment.
[0057] The implementation principle of this embodiment is as follows: during detection, the bottom of the wine bottle 2 to be detected is fixed in the placement groove 11 of the base 1, and then the operating rod 5 is operated to make the operating rod 5 move vertically downward in the through hole 41. During the movement, the detection plunger 6 is driven to extend into the bottle mouth of the wine bottle 2 to be detected until the detection plunger 6 is in close contact with the inner wall surface of the bottle mouth. At this time, the protrusion on the inner wall surface of the bottle mouth is detected by the pressure sensitive film on the detection plunger 6. Since the pressure of the protrusion on the inner wall of the bottle mouth is different from the pressure displayed by the smooth inner wall surface, if there is a protrusion on the inner wall surface of the bottle mouth, when the detection plunger 6 is in close contact with the inner wall surface of the bottle mouth, the surface protrusion will squeeze the detection plunger 6, so that the pressure sensitive film senses the pressure change, and then transmits the pressure change to the controller in the form of an electrical signal. The controller then controls the corresponding display to display the pressure change, and then judges the protrusion on the inner wall surface of the bottle mouth of the wine bottle 2 to be detected according to the pressure change. This detection method has a fast detection speed and can quickly detect the inner wall of the bottle mouth through a pressure-sensitive membrane. At the same time, this method is easy to operate and use. In addition, this detection method has high detection accuracy and low false detection rate. It can accurately detect small surface protrusions on the inner wall of the bottle mouth. At the same time, it can effectively resist the interference of factors such as inattention and visual fatigue in artificial sensory detection, and the false detection rate is no more than 0.1%.
[0058] Embodiment 2
[0059] Please refer to Figure 3As shown, the difference between the second embodiment and the first embodiment is that multiple wine bottles 2 to be detected can be detected simultaneously, specifically:
[0060] A frame 8 is provided, and a base 1 is installed at the bottom of the frame 8. The base 1 is set in a disc shape. A circle of wine bottles 2 to be detected can be placed on the base 1 at the same time. It can be understood that a circle of wine bottles 2 to be detected is arranged in a circular array with the center of the base 1 as the center. An integrated disk 9 is installed on the top of the frame 8. The integrated disk 9 and the base 1 are arranged correspondingly up and down. A circle of operating rods 5 are installed on the integrated disk 9. The number and position of the operating rods 5 and the wine bottles 2 to be detected are arranged one by one. A disc 7 is installed at the lower end of the operating rod 5. The lower surface of the disc 7 is installed with a detection plunger 6. It can be understood that each detection plunger 6 corresponds to each wine bottle 2 to be detected. Therefore, these operating rods 5 can be operated at the same time during the detection, so that the operating rod 5 moves downward to make the detection plunger 6 extend into the bottle mouth of the wine bottle 2 to be detected until it is in close contact, and then the detection is completed. Preferably, the operating rod 5 can be a cylinder, and the disc 7 is installed on the output rod of the cylinder, and then the cylinder can achieve automatic extension and retraction, and then the detection is convenient.
[0061] In some embodiments, in order to ensure the stability of the wine bottle 2 to be tested, a circle of placement grooves 11 can be provided on the base 1, each placement groove 11 corresponds to a wine bottle 2 to be tested, and the placement grooves 11 are set to be cylindrical to facilitate the bottom installation of the wine bottle 2 to be tested.
[0062] In some embodiments, an inlet 81 and an outlet 82 are respectively provided on opposite sides of the frame 8, and conveyor belts 10 are respectively provided at the inlet 81 and the outlet 82. The conveyor belt 10 of the inlet 81 is used to convey the wine bottles 2 to be inspected into the base 1 inside the frame 8, and the conveyor belt 10 of the outlet 82 is used to convey the wine bottles that have completed the inspection on the base 1 to the next process. The ends of the two conveyor belts 10 are respectively attached to the outer periphery of the base 1, and the base 1 is configured to be set to rotate around its own axis at the bottom of the frame 8. For example, a stepper motor 12 can be set at the bottom of the base 1, and the output shaft of the stepper motor 12 drives the base 1 to rotate. The specific arrangement is not specifically limited in this embodiment.
[0063] Side baffles 11 are continuously arranged on both sides of the conveyor belt 10 and on the periphery of the upper surface of the base 1. The side baffles 11 can prevent the wine bottles 2 to be inspected from tipping over during the conveying process. At the same time, the wine bottles 2 to be inspected on the base 1 are always close to the side baffles 11 during the rotation of the base 1.
[0064] During the inspection, the conveyor belt 10 of the inlet 81 conveys the wine bottles 2 to be inspected to the base 1 in sequence, and the stepper motor 12 controls the rotation of the base 1 to place the wine bottles 2 to be inspected on the base 1 in sequence, and then the conveyor belt 10 of the inlet 81 is stopped. At this time, by operating the operating rod 5, the detection plunger 6 at the lower end of each operating rod 5 is extended into the bottle mouth of the wine bottle 2 to be inspected until it is in close contact, and the detection is completed by the induction of the pressure sensitive membrane and the inner wall of the bottle mouth. For the wine bottles with normal test results, they can be transmitted to the next process through the conveyor belt 10 of the outlet 82, while the wine bottles with abnormal test results are rejected.
[0065] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
