Description

Technical Field

[0001] The 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] For products such as wine, glass bottles or porcelain bottles are usually used for storage. However, glass bottles or porcelain bottles are prone to cracks during the production process. Some cracks are very small and cannot be observed with the naked eye. Using bottles with cracks to store wine will not only cause the wine to leak, but also be detrimental to the storage of the wine. For this reason, wine bottle processing companies and wine product manufacturers will conduct crack detection on wine bottles.

[0003] The applicant has previously applied for a patent CN106932159A, which discloses a device and method for detecting the sealing of glass and ceramic containers. A grounded outer cover is provided outside the bottle body, and a positive electrode is inserted into the bottle body. If there is a crack on the bottle body, the electrodes inside and outside the bottle body will generate electron breakdown through the crack, forming a leakage current, thereby detecting the presence of cracks in the bottle body. In this patent, the outer cover and the positive electrode are covered on the bottle body from top to bottom. After actual use by the applicant, this detection device is suitable for columnar bottles with relatively regular shapes. However, for some bottles with undulating side walls, such as the bottle shape shown in the drawings of this application specification, the outer cover cannot fit the side walls of the bottle body, especially the bottom of the bottle body, resulting in poor detection effect of the detection device on such bottles and inaccurate detection results.

[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 solution of the present invention is as follows: An upward-moving negative ion discharge bottle body 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; The mobile platform is provided with a bottle placing platform and an electrode insulating cover, and a second driver for driving the electrode insulating cover to move. The electrode insulating cover is arranged to be able to slide laterally, approaching or moving away from the bottle placing platform. A bottle containing groove is arranged on the side of the electrode insulating cover close to the bottle placing platform, and a positive discharge electrode is arranged in the bottle containing groove. A negative discharge electrode is provided above the bottle placing platform, which is fixed on the fixed platform and has a bottle pressing mechanism on its outer side, which is used to press the bottle mouth; The negative discharge electrode is inserted into the bottle body by moving the platform upward.

[0007] The electrode insulation cover moves laterally and covers the bottle body, so that the positive electrode fits the contour of the bottle side wall more closely, improving the detection effect and result accuracy.

[0008] 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 insulating cover and is higher than the electrode insulating cover. It is used to seal the bottle slot when the mobile platform moves up to prevent the bottle body from tipping out of the bottle slot when the mobile platform moves up, and at the same time seal the discharge space.

[0009] In order to comprehensively detect cracks on the side wall of the bottle body, a positive discharge electrode is provided on the side of the sealing plate facing the bottle tank.

[0010] 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.

[0011] In order to fit the bottle body, a groove matching the contour of the side wall of the bottle body is provided on the positive discharge electrode in the bottle holding tank, and the bottle body is located in the groove during detection.

[0012] 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.

[0013] 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.

[0014] The bottle pressing member presses the bottle mouth under the drive of the third driver, fixes the bottle body in the bottle holding groove, 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.

[0015] 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.

[0016] Preferably, the detection device also includes an automatic feeding mechanism to reduce manual work.

[0017] The present application also provides a detection method, based on the above-mentioned upward-moving negative ion discharge bottle body crack detection device, comprising the following steps: S1: Place the bottle on the bottle placing table, and move the electrode insulation cover horizontally toward the bottle placing table to cover the bottle; S2: The bottle pressing mechanism presses the bottle mouth; 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; 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; S5: After the inspection is completed, the mobile platform moves down, and after it stops, the electrode insulation cover moves away from the bottle placing platform to remove the bottle body.

[0018] The present invention provides an upward-moving negative ion discharge bottle body crack detection device and detection method, which enables the positive discharge electrode to better fit the contour shape of the side wall of the special-shaped bottle through the lateral movement of the electrode insulation cover, so that the detection effect is better and the detection accuracy is improved.

[0019] In addition, the electrode insulation cover, bottle body, etc. are moved upward, which can simplify the structure of the negative discharge electrode connection part, and can also reduce the avoidance action and avoidance stroke of the robotic arm when using the robotic arm, thereby improving efficiency and reducing safety hazards.

[0022] Embodiment 1: Figures 1 to 3As 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-columnar bottle bodies, such as the bottle body with a drum shape in the middle as shown in the figure. Compared with the existing technology, it can make the electrode fit the bottle body more closely and improve the detection accuracy.

[0023] The detection device comprises 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 which can drive the mobile platform 2 to move up and down.

[0024] The detection device can be loaded manually or by an automatic loading mechanism. The automatic loading mechanism can be, for example, the robot arm 4 shown in the figure.

[0025] The mobile platform 2 is provided with a bottle placing platform 21 and an electrode insulating cover 22, and 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 one 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.

[0026] 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 for pressing the bottle mouth.

[0027] The negative discharge electrode 32 is inserted into the bottle body by moving the mobile platform 2 upward.

[0028] Specifically, in this embodiment, the fixed platform 3 is fixed on the base 1 through a plurality of support columns 11, and the mobile platform 2 is slidably connected to at least two support columns 11, and can move up and down between the base 1 and the fixed platform 3 under the drive of the first driver 31. The first driver 31 is arranged on the fixed platform 3, and its driving end extends downward and is fixedly connected to the mobile platform 2.

[0029] The bottle placing platform 21 is arranged on the top of the mobile platform 2, close to one side of the mobile platform 2. The second driver 24 is arranged on the mobile platform 2, and is located at a side opposite to the position of the bottle placing platform 21. The electrode insulating cover 22 is located between the bottle placing platform 21 and the second driver 24. The mobile platform 2 may also be provided with a slide rail 26. The slide rail 26 may be provided with two rails parallel to each other. The bottom surface of the electrode insulating cover 22 is slidably matched with the slide rail 26. The second driver 24 drives the electrode insulating cover 22 to slide along the slide rail 26 to approach or move away from the bottle placing platform 21.

[0030] The bottle placing platform 21 preferably protrudes upward from the moving platform 2. The lower part of the bottle containing groove 221 is connected to the bottom surface of the electrode insulating cover 22 to accommodate the bottle placing platform 21. While allowing the bottle body to enter the bottle containing groove 221, the bottle placing platform 21 blocks the moving path of the electrode insulating cover 22 to prevent the electrode insulating cover 22 from being pushed excessively and pushing the bottle body down, thereby limiting and stopping the electrode insulating cover 22.

[0031] In addition, a pressure sensor may be provided at the lower part of the bottle receiving tank 221, corresponding to the level of the bottle placing platform 21. A control unit may be provided on the device to communicate with the pressure sensor. When the bottle enters the bottle receiving tank 221, the pressure sensor touches the bottle placing platform 21. After receiving the touch signal, the control unit controls the second driver 24 to stop running, and further prevents the electrode insulating cover 22 from excessive movement.

[0032] The upper portion of the bottle receiving groove 221 is connected to the top surface of the electrode insulating cover 22 so as to expose the bottle mouth upwards, and the bottle pressing mechanism 25 moves downwards from this position to press the bottle mouth.

[0033] The positive discharge electrode 23 is detachably disposed in the bottle receiving groove 221 , and is provided with a groove matching the contour of the side wall of the bottle body. During detection, the bottle body is located in the groove.

[0034] The electrode insulating cover 22 is set to wrap the bottle body from the side, so that a groove of a corresponding shape can be opened in advance on the positive electrode 23 in the bottle receiving groove 221 according to the shape of the bottle body, so that the positive electrode 23 can fit the side wall of the bottle body very well and perform better detection on the bottle body.

[0035] 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 placing platform 21 away from the electrode insulating cover 22, and is higher than the electrode insulating cover 22. It is used to block the bottle containing groove 221 when the mobile platform 2 moves upward, to prevent the bottle body from pouring out of the bottle containing groove 221 when the mobile platform 2 moves upward, and to block the discharge space at the same time.

[0036] In order to comprehensively detect cracks on the side wall of the bottle body, a positive discharge electrode 23 is provided on the side of the sealing plate 33 facing the bottle receiving groove 221 .

[0037] 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 placing platform 21 .

[0038] 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 containing tank 221 to wrap the bottle body, and jointly perform a comprehensive and complete inspection on the bottle body.

[0039] In addition, the side of the positive discharge electrode 23 close to the bottle body is preferably provided with dense serrations.

[0040] 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 arranged on the support frame 27, and the bottle pressing part 251 is sleeved on the negative discharge electrode 32.

[0041] The bottle pressing member 251 is driven by the third driver 252 to press the bottle mouth, and together with the bottle placing platform 21, clamps the bottle body and fixes it in the bottle containing 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.

[0042] 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 the electrode insulation cover 22 and other structures 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 of the mobile platform 2 when sliding, and makes the sliding of the mobile platform 2 smooth.

[0043] 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 touch the support frame 27 when the mobile platform 2 moves up, so as to stop the first driver 31. The pressure sensor on the mobile platform 2 is used to touch the base 1 when the mobile platform 2 moves down, so as to stop the first driver 31. The mobile platform 2 is damaged due to excessive up and down movement.

[0044] In this embodiment, the first driver 31, the second driver 24 and the third driver 252 are preferably hydraulic cylinders or pneumatic cylinders.

[0045] In this embodiment, dense discharge needles (not shown in the figure) extending radially outward are provided at the lower part of the negative discharge electrode 32 .

[0046] The detection device provided in this embodiment, through the lateral movement of the electrode insulating cover 22, enables the positive discharge electrode 23 to be more closely fitted to the contour shape of the side wall of the special-shaped bottle, so that the detection effect is better and the detection accuracy is improved. The electrode insulating cover 22, the bottle body, etc. adopt an upward movement method, which simplifies the structure of the connection part of the negative discharge electrode 32. In addition, as mentioned above, the detection device of the present invention can also include a mechanical arm 4 for automatic loading, which takes and places the bottle body on the bottle placing platform 21. After the mechanical arm 4 is placed on the bottle body, it only needs to move outward a short distance to avoid the moving platform 2. It can also be made that the part of the mobile platform 2 where the bottle placing platform 21 is set protrudes outward, and the width is equal to or less than the corresponding width of the bottle body, so that the mechanical arm 4 does not need to move after the bottle is released and placed, and does not affect the upward movement of the moving platform 2. If the bottle pressing mechanism and the electrode entering the bottle mouth still adopt a downward movement working structure, since the sealing baffle 33 must be avoided, the avoidance action and avoidance stroke of the mechanical arm 4 are increased, and there are also safety hazards in operation.

[0047] Embodiment 2: The present application also provides a detection method, based on the detection device of Embodiment 1, comprising the following steps: S1: placing the bottle body 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; S2: The bottle pressing mechanism 25 presses the bottle mouth; Specifically, the third driver 252 drives the bottle pressing member 251 to move downward, presses the bottle mouth, and fixes the bottle body; S3: The first driver 31 drives the mobile platform 2, driving the bottle body, the electrode insulating cover 22, and the bottle pressing mechanism 25 to move upward together, so that the negative discharge electrode 32 is inserted into the bottle body, and at the same time, the sealing plate 33 blocks the side opening of the bottle receiving groove 221; 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 current is generated in the circuit connecting the two. If there are cracks on the bottle body, current will be generated in the circuit connecting the positive discharge electrode 23 and the negative discharge electrode 32.

[0048] 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.

[0049] Embodiment 3: As mentioned above, the bottle body accommodating space of the electrode insulating cover 22 corresponding to the bottle accommodating groove 221 of the present invention is determined according to the customer's inspection batch and use requirements, and can be a fixed space as shown in Embodiment 1, or an adjustable space.

[0050] like Figure 4 and Figure 5As shown, this embodiment provides an example for the above adjustable space. In this example, the structure of the detection device is basically the same as that of the detection device of the first embodiment, except that the electrode insulation cover 22 corresponding to the two opposite sides of the bottle receiving tank 221 is composed of a plurality of sliders 28, the plurality of sliders 28 are arranged vertically and connected to the electrode insulation cover 22 in a horizontal sliding manner, and the plurality of sliders 28 are each provided with a positive discharge electrode 23 on one side of the bottle receiving tank 221.

[0051] 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 side wall 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.

[0052] In order to prevent the slider 28 from moving during detection, a locking plate 29 is provided on the side of the electrode insulating cover 22 away from the bottle placing platform 21, and a distance adjusting bolt 291 is provided between the locking plate 29 and the electrode insulating cover 22, and the distance between the locking plate 29 and the electrode insulating cover 22 can be adjusted by the distance adjusting bolt 291. The slider 28 is provided with a fixing column 281 extending toward the locking plate 29, and the outer end of the fixing column 281 is clamped on the outer side of the locking plate 29, and the electrode insulating cover 22 and the locking plate 29 are provided with a slide groove for cooperating with the sliding of the slider 28.

[0053] 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.

[0054] 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.
