Description

Technical Field

[0001] The present invention relates to the technical field of bottle body detection, and in particular to an upward-moving negative ion discharge bottle body crack detection device and a detection method. Background Art

[0002] Wine and other products are typically bottled in glass or porcelain bottles, which are prone to cracking during the production process. Some cracks are so small they can't be seen with the naked eye. Using cracked bottles to hold wine can cause leakage and hinder storage. Therefore, both wine bottle processing companies and wine product manufacturers perform crack inspections on their bottles.

[0003] The applicant previously applied for patent CN106932159A, which discloses a device and method for testing the sealing properties of glass and ceramic containers. The device comprises a grounded outer cover on the outside of the bottle and a positive electrode inserted into the bottle. If a crack is present on the bottle, the electrodes inside and outside the bottle will generate electron breakdown through the crack, forming a leakage current, thereby detecting the presence of a crack. In this patent, the cover and positive electrode are applied downwards to the bottle. In actual use by the applicant, this testing device is suitable for relatively regular cylindrical bottles. However, for bottles with undulating sidewalls, such as those shown in the drawings of this application, the cover cannot conform to the sidewalls, especially the bottom of the bottle. This results in poor detection performance and inaccurate test results for such bottles.

[0004] In addition, if the bottle pressing mechanism and the electrode entering the bottle mouth still use the current downward-moving working structure, on the one hand, it will increase the movement burden of multiple upper components. Moreover, when a robotic arm is used instead of manual labor to place the wine bottle on the detection device, the avoidance action and avoidance stroke of the robotic arm will be increased due to mechanism interference, affecting efficiency and posing potential safety hazards. Summary of the Invention

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides an upward-moving negative ion discharge bottle body crack detection device and detection method.

[0006] The technical solutions of the present invention are as follows:

[0007] An upward-moving negative ion discharge bottle crack detection device comprises a base, a mobile platform and a fixed platform arranged from bottom to top, wherein the fixed platform is provided with a first driver capable of driving the mobile platform to move up and down;

[0008] The mobile platform is provided with a bottle placing platform and an electrode insulating cover, as well as a second driver for driving the electrode insulating cover to move. The electrode insulating cover is configured to be able to slide laterally, approaching or moving away from the bottle placing platform. A bottle receiving groove is provided on the side of the electrode insulating cover close to the bottle placing platform, and a positive discharge electrode is provided in the bottle receiving groove.

[0009] A negative discharge electrode is provided above the bottle placing table. The negative discharge electrode is fixed on the fixed platform. A bottle pressing mechanism is provided on the outer side of the negative discharge electrode to press the bottle mouth.

[0010] The negative discharge electrode is inserted into the bottle body by moving the platform upward.

[0011] The electrode insulation cover moves laterally and covers the bottle body, so that the upright electrode fits the contour shape of the bottle side wall more closely, improving the detection effect and result accuracy.

[0012] In order to further stabilize the bottle body, a sealing plate is provided on the fixed platform. The sealing plate is located on the side of the bottle placement platform away from the electrode insulation cover, and its height is higher than the electrode insulation cover. It is used to block the bottle tank when the mobile platform moves up, to prevent the bottle body from tipping out of the bottle tank when the mobile platform moves up, and to block the discharge space at the same time.

[0013] In order to fully detect cracks on the side walls of the bottle body, a positive discharge electrode is provided on the side of the sealing plate facing the bottle tank.

[0014] In order to detect cracks on the bottom wall of the bottle body, a positive discharge electrode is provided on the top surface of the bottle placement table, which cooperates with the positive discharge electrode on the sealing plate and the positive discharge electrode in the bottle holding tank to carry out a complete inspection of the bottle body.

[0015] In order to fit the bottle body, a groove matching the side wall contour of the bottle body is provided on the positive electrode in the bottle holding tank, and the bottle body is located in the groove during detection.

[0016] In the present application, the bottle pressing mechanism includes a bottle pressing member and a third driver for driving the bottle pressing member to move up and down, and the bottle pressing member is sleeved on the negative discharge electrode.

[0017] Specifically, a support frame is provided on the mobile platform and is mounted above the electrode insulation cover, and the third driver is arranged on the support frame.

[0018] Driven by the third driver, the bottle pressing member presses the bottle mouth, fixes the bottle body in the bottle holding tank, and aligns the negative discharge electrode with the bottle mouth. The mobile platform drives the bottle pressing mechanism to rise together through the support frame to ensure that the bottle body is always pressed by the bottle pressing member.

[0019] Preferably, the bottle body accommodating space of the electrode insulating cover corresponding to the bottle accommodating groove is a fixed space or an adjustable space.

[0020] Preferably, the detection device further includes an automatic loading mechanism to reduce manual work.

[0021] The present application also provides a detection method based on the above-mentioned upward-moving negative ion discharge bottle crack detection device, comprising the following steps:

[0022] S1: Place the bottle on the bottle placement table, and move the electrode insulation cover horizontally toward the bottle placement table to cover the bottle;

[0023] S2: The bottle pressing mechanism presses the bottle mouth;

[0024] S3: The mobile platform drives the bottle body, the electrode insulation cover, and the bottle pressing mechanism to move upward, so that the negative discharge electrode is inserted into the bottle body;

[0025] S4: Apply high voltage to the positive discharge electrode and the negative discharge electrode to detect whether current is generated in the circuit connecting the two;

[0026] S5: After the inspection is completed, the mobile platform moves down. After it stops, the electrode insulation cover moves away from the bottle placement platform to remove the bottle body.

[0027] The present invention provides an upward-moving negative ion discharge bottle body crack detection device and detection method. By moving the electrode insulation cover horizontally, the positive discharge electrode can better fit the contour shape of the side wall of the special-shaped bottle, thereby improving the detection effect and the detection accuracy.

[0028] In addition, the electrode insulation cover, bottle body, etc. are moved upward, which can simplify the structure of the negative discharge electrode connection part. It can also reduce the avoidance action and avoidance stroke of the robotic arm when using the robotic arm, improve efficiency and reduce safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 1: Figures 1 to 3 As shown, this embodiment provides an upward-moving negative ion discharge bottle body crack detection device (hereinafter referred to as the detection device), which is used to detect whether there are cracks on the bottle body, especially for some non-cylindrical bottle bodies, such as the bottle body with a drum shape in the middle as shown in the figure. Compared with the existing technology, the electrode can be more closely fitted to the bottle body, thereby improving the detection accuracy.

[0038] The detection device includes a base 1, a mobile platform 2 and a fixed platform 3 arranged from bottom to top. The fixed platform 3 is provided with a first driver 31 that can drive the mobile platform 2 to move up and down.

[0039] The detection device can be loaded manually or by an automatic loading mechanism. The automatic loading mechanism can be, for example, the robotic arm 4 shown in the figure.

[0040] The mobile platform 2 is provided with a bottle placing platform 21 and an electrode insulating cover 22, as well as a second driver 24 for driving the electrode insulating cover 22 to move. The electrode insulating cover 22 is configured to be able to slide laterally, approaching or moving away from the bottle placing platform 21. A bottle receiving groove 221 is provided on the side of the electrode insulating cover 22 close to the bottle placing platform 21, and a positive discharge electrode 23 is provided in the bottle receiving groove 221.

[0041] A negative discharge electrode 32 is provided above the bottle placing platform 21 . The negative discharge electrode 32 is fixed on the fixed platform 3 , and a bottle pressing mechanism 25 is sleeved on the outer side thereof. The bottle pressing mechanism 25 is used to press the bottle mouth.

[0042] The negative discharge electrode 32 is inserted into the bottle body by moving the platform 2 upward.

[0043] Specifically, in this embodiment, the fixed platform 3 is fixed to the base 1 via a plurality of support columns 11, and the mobile platform 2 is slidably connected to at least two of the support columns 11 and is capable of moving up and down between the base 1 and the fixed platform 3 under the drive of the first actuator 31. The first actuator 31 is disposed on the fixed platform 3, with its driving end extending downward and fixedly connected to the mobile platform 2.

[0044] The bottle placement platform 21 is disposed on top of the mobile platform 2, near one side of the mobile platform 2. A second actuator 24 is disposed on the mobile platform 2, on the side opposite the bottle placement platform 21. The electrode insulating cover 22 is positioned between the bottle placement platform 21 and the second actuator 24. The mobile platform 2 is also preferably provided with two parallel rails 26. The bottom surface of the electrode insulating cover 22 slidably engages the rails 26. The second actuator 24 drives the electrode insulating cover 22 to slide along the rails 26 to move it closer to or further from the bottle placement platform 21.

[0045] The bottle placement platform 21 preferably protrudes upward from the movable platform 2. The lower portion of the bottle receiving groove 221 communicates with the bottom surface of the electrode insulating cover 22 to accommodate the bottle placement platform 21. While allowing bottles to enter the bottle receiving groove 221, the bottle placement platform 21 blocks the movement path of the electrode insulating cover 22, preventing the electrode insulating cover 22 from over-pushing and knocking over the bottles, thereby limiting and stopping the electrode insulating cover 22.

[0046] In addition, a pressure sensor may be provided at the lower portion of the bottle receiving tank 221, corresponding horizontally to the bottle placing platform 21. A control unit may also be provided on the device to communicate with the pressure sensor. When the bottle enters the bottle receiving tank 221, the pressure sensor contacts the bottle placing platform 21. Upon receiving the contact signal, the control unit controls the second driver 24 to stop operating, thereby preventing the electrode insulating cover 22 from moving excessively.

[0047] The upper portion of the bottle holding tank 221 is connected to the top surface of the electrode insulating cover 22 so as to expose the bottle opening upwards. The bottle pressing mechanism 25 moves downwards from this position to press the bottle opening.

[0048] The upright electrode 23 is detachably disposed in the bottle receiving groove 221 , and is provided with a groove matching the contour of the bottle sidewall. During detection, the bottle is located in the groove.

[0049] The electrode insulating cover 22 is set to wrap the bottle body from the side. In this way, a groove of corresponding shape can be opened on the positive discharge electrode 23 in the bottle receiving groove 221 according to the shape of the bottle body, so that the positive discharge electrode 23 can fit the side wall of the bottle body very well, and the bottle body can be better inspected.

[0050] In order to further stabilize the bottle body, a sealing plate 33 is provided on the fixed platform 3. The sealing plate 33 is located on the side of the bottle placement platform 21 away from the electrode insulation cover 22 and is higher than the electrode insulation cover 22. It is used to block the bottle receiving groove 221 when the mobile platform 2 moves upward, to prevent the bottle body from pouring out of the bottle receiving groove 221 when the mobile platform 2 moves upward, and to block the discharge space at the same time.

[0051] In order to comprehensively detect cracks on the bottle sidewall, a positive discharge electrode 23 is provided on the side of the sealing plate 33 facing the bottle receiving tank 221 .

[0052] In order to detect cracks on the bottom wall of the bottle body, a positive discharge electrode 23 is provided on the top surface of the bottle placement platform 21.

[0053] The sealing plate 33 and the positive discharge electrode 23 on the bottle placing platform 21 are plate-shaped, and cooperate with the positive discharge electrode 23 in the bottle receiving tank 221 to wrap the bottle body and jointly perform comprehensive and complete inspection on the bottle body.

[0054] In addition, the side of the positive discharge electrode 23 close to the bottle body is preferably provided with dense serrations.

[0055] The mobile platform 2 is also provided with a support frame 27, which is mounted above the electrode insulating cover 22. The bottle pressing mechanism 25 includes a bottle pressing part 251 and a third driver 252 that drives the bottle pressing part 251 to move up and down. The third driver 252 is set on the support frame 27, and the bottle pressing part 251 is sleeved on the negative discharge electrode 32.

[0056] Driven by the third driver 252, the bottle pressing member 251 presses the bottle mouth, and together with the bottle placing platform 21, clamps the bottle body and fixes it in the bottle receiving groove 221, and at the same time aligns the negative discharge electrode 32 with the bottle mouth. The movable platform 2 drives the bottle pressing mechanism 25 to rise together through the support frame 27 to ensure that the bottle body is always pressed by the bottle pressing member 251, and at the same time, the negative discharge electrode 32 is accurately and smoothly inserted into the bottle body.

[0057] In this embodiment, the top of the support frame 27 is slidably connected to at least two support columns 11, and together with the mobile platform 2, it supports structures such as the electrode insulation cover 22 on the mobile platform 2, making the support structure more stable. At the same time, it reduces the lateral force between the mobile platform 2 and the support columns 11, reduces the friction resistance when the mobile platform 2 slides, and makes the sliding of the mobile platform 2 smooth.

[0058] In this embodiment, pressure sensors are also provided on the fixed platform 3 and the mobile platform 2, which are electrically connected to the control unit. The pressure sensor on the fixed platform 3 is used to contact the support frame 27 when the mobile platform 2 moves upward, thereby stopping the first driver 31. The pressure sensor on the mobile platform 2 is used to contact the base 1 when the mobile platform 2 moves downward, thereby stopping the first driver 31, so that the mobile platform 2 is damaged due to excessive up and down movement.

[0059] In this embodiment, the first driver 31 , the second driver 24 and the third driver 252 are preferably hydraulic cylinders or pneumatic cylinders.

[0060] In this embodiment, dense discharge needles (not shown in the figure) extending radially outward are provided at the lower portion of the negative discharge electrode 32 .

[0061] The detection device provided in this embodiment utilizes the lateral movement of the electrode insulating cover 22, allowing the positive discharge electrode 23 to more closely conform to the contours of the sidewalls of irregularly shaped bottles, resulting in improved detection results and increased detection accuracy. The upward movement of the electrode insulating cover 22 and the bottle body simplifies the structure of the connection portion of the negative discharge electrode 32. Furthermore, as previously mentioned, the detection device of the present invention may also include a robotic arm 4 for automatic loading, which places bottles on the bottle placement platform 21. With the structure of this embodiment, after placing a bottle, the robotic arm 4 only needs to move outward a short distance to clear the movable platform 2. Alternatively, by designating the portion of the movable platform 2 on which the bottle placement platform 21 is located to protrude outward, with a width equal to or less than the corresponding width of the bottle, the robotic arm 4 does not need to move after releasing the bottle and does not affect the upward movement of the movable platform 2. If the bottle pressing mechanism and the electrodes entering the bottle mouth still operate in a downward-moving manner, the sealing plate 33 must be cleared, increasing the clearance movement and clearance stroke of the robotic arm 4, and posing a safety hazard during operation.

[0062] Example 2: This application also provides a detection method, based on the detection device of Example 1, comprising the following steps:

[0063] S1: The bottle body is placed on the bottle placing platform 21, and the second driver 24 drives the electrode insulating cover 22 to move horizontally toward the bottle placing platform 21 to cover the bottle body;

[0064] S2: The bottle pressing mechanism 25 presses the bottle mouth;

[0065] Specifically, the third driver 252 drives the bottle pressing member 251 to move downward, pressing the bottle mouth and fixing the bottle body;

[0066] S3: The first driver 31 drives the mobile platform 2, which drives the bottle body, the electrode insulating cover 22, and the bottle pressing mechanism 25 to move upward, so that the negative discharge electrode 32 is inserted into the bottle body, and the sealing plate 33 blocks the side opening of the bottle receiving groove 221;

[0067] S4: Apply high voltage to the positive discharge electrode 23 and the negative discharge electrode 32 to establish an electric field inside and outside the bottle body, and detect whether there is current generated in the circuit connecting the two. If there is a crack on the bottle body, current will be generated in the circuit connecting the positive discharge electrode 23 and the negative discharge electrode 32.

[0068] S5: After the detection is completed, the first driver 31 drives the movable platform 2 to move downward. After the movable platform 2 stops moving, the second driver 24 drives the electrode insulating cover 22 to move away from the bottle placing platform 21 to expose and remove the bottle body.

[0069] Embodiment 3: As mentioned above, the bottle accommodating space of the bottle accommodating tank 221 corresponding to the electrode insulating cover 22 of the present invention is determined according to the customer's inspection batch and usage requirements. It can be a fixed space as shown in embodiment 1 or an adjustable space.

[0070] like Figure 4 and Figure 5 As shown, this embodiment provides an example of the aforementioned adjustable space. The structure of the detection device in this example is essentially the same as that of the detection device in Example 1, except that the portions of the electrode insulating cover 22 corresponding to the transversely opposite sides of the bottle receiving tank 221 are composed of a plurality of sliders 28 . These sliders 28 are arranged vertically and laterally slidably connected to the electrode insulating cover 22 . Each of the sliders 28 is provided with a positive discharge electrode 23 on one side of the bottle receiving tank 221 .

[0071] Before using the detection device, the horizontal position of each slider 28 can be adjusted according to the shape of the bottle to be detected to adapt to the contour of the bottle sidewall, so that the positive electrode 23 fits the bottle as closely as possible. The number of sliders 28 can be adjusted according to actual needs, and in this embodiment, 10-20 are preferred.

[0072] To prevent the slider 28 from moving during testing, a locking plate 29 is installed on the side of the electrode insulation cover 22 away from the bottle placement platform 21. An adjustable bolt 291 is installed between the locking plate 29 and the electrode insulation cover 22. The adjustable bolt 291 can be used to adjust the distance between the locking plate 29 and the electrode insulation cover 22. A fixing post 281 extends from the slider 28 toward the locking plate 29. The outer end of the fixing post 281 is clamped on the outside of the locking plate 29. The electrode insulation cover 22 and the locking plate 29 are provided with a sliding groove that cooperates with the sliding movement of the slider 28.

[0073] When the position of the slider 28 needs to be fixed, the distance adjusting bolt 291 is rotated to increase the distance between the locking plate 29 and the electrode insulating cover 22. The locking plate 29 pushes the outer end of the fixing column 281, and then the slider 28 is pulled toward the electrode insulating cover 22 through the fixing column 281 to press it against the electrode insulating cover 22.

[0074] In addition to adding space adjustment, the detection method of this embodiment still follows the operation of the second embodiment and will not be described in detail.
