Description

Technical Field

[0001] This invention relates to the field of sealing test technology, and in particular to a multi-station rotary testing device, system and method for sealing tests. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Packaging airtightness testing is mainly used for detecting minute leaks in packaging and for detecting leaks in the integrity of sealed containers. Most existing airtightness testing systems use a vacuum method to test the sample located in the test chamber. The test chamber includes an upper test chamber and a lower test chamber, and the sample is tested through the sealed space formed by the upper test chamber and the lower test chamber.

[0004] The inventors discovered that with existing testing methods, the upper test chamber needs to be opened before each test, and the sample needs to be placed in the lower test chamber. The upper and lower test chambers are combined to form a sealed space for testing. After the test is completed, the sample needs to be manually removed from the test chamber before another sample is placed for testing. The efficiency of continuous testing is low.

[0005] Meanwhile, existing methods include using robotic arms to continuously grip samples. This approach generally requires high costs and precise control of the robotic arm, carries the risk of damaging the sample, and necessitates calibration and adjustment of the robotic arm each time the testing position is changed, resulting in low work efficiency.

Detailed Implementation

[0085] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0086] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0087] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0088] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0089] Example 1:

[0090] Embodiment 1 of the present invention provides a multi-station rotary testing device for sealing performance testing, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes: a first test chamber 1 and a second test chamber 2;

[0091] The first test chamber 1 has a first test cavity 3. The second test chamber 2 is a rotating test chamber with a horizontal axis 12. At least one second test cavity 4 is opened on the rotating test chamber. The first test cavity 3 is used to cooperate with the second test cavity 4 under the drive of the first drive mechanism to form a sealed space for accommodating the sample 17.

[0092] In this embodiment, the second test cavity 4 is opened on the outer plane of the rotating test cavity, and at least one second test cavity 4 is opened on each outer plane;

[0093] In one alternative implementation, a second test chamber 4 is formed on each outer plane, so that a sample 17 is inserted at a time. After the sample is inserted, the test chamber is rotated, and the second test chamber 4 cooperates with the first test chamber 3 to seal the sample 17 and perform a sealing test on the sample 17. After the test is completed, the first test chamber 3 and the second test chamber 4 are separated, and the test chamber is rotated again to test the next sample 17.

[0094] In another alternative implementation, each outer plane has multiple (e.g., three, four, five or more) second test chambers 4, and the number of second test chambers 4 on each outer plane is the same (e.g., the number of second test chambers 4 on each outer plane is 5, and the spacing between adjacent second test chambers 4 on each outer plane is the same). The first test chamber 1 has the same number of first test chambers 3 as the number of second test chambers 4 on any outer plane, and they are matched one-to-one (that is, no matter which outer plane is rotated to a position opposite to the first test chamber 1, the same number of first test chambers 3 are matched with the second test chambers 4 to realize the testing of multiple samples 17).

[0095] Understandably, in some other implementations, multiple first test chambers 1 may also be included. The number of first test chambers 3 and second test chambers 4 on each side of each first test chamber 1 are the same and they are matched one by one. That is, each first test chamber 3 is configured with a first test chamber 1 so that no matter which outer plane is rotated to be opposite to the position of the first test chamber 1, there are always the same number of first test chambers 3 and second test chambers 4 to achieve the testing of multiple samples 17.

[0096] Preferably, the rotating test chamber includes four vertically adjacent outer planes, and at least one second test chamber 4 is provided on each outer plane; it can be understood that the cross section of the rotating test chamber perpendicular to the rotation axis 12 can be a square (obtained by rounding the four corners of a square). In this embodiment, only one second test chamber 4 is provided on each outer plane, and the second test chambers 4 on each outer plane are symmetrically arranged along the rotation axis 12.

[0097] Specifically, the rotating test chamber includes a first outer plane, a second outer plane, a third outer plane, and a fourth outer plane that are sequentially adjacent to each other. Each of the first outer plane, the second outer plane, the third outer plane, and the fourth outer plane has a second test chamber 4. After the sample is introduced into the second test chamber 4 on the first outer plane, the rotating test chamber rotates 90° clockwise. At this time, the second test chamber 4 cooperates with the first test chamber 3 to seal the first test chamber 3 (at this time, the first test chamber is directly above the second test chamber). Then, a vacuum test is performed. The second test chamber 4 on the fourth outer plane is injected with the sample again and waits. After the sample 17 in the second test chamber 4 on the first outer plane is tested, the first test chamber 3 and the second test chamber 4 are separated. At this time, the rotating test chamber rotates 90° clockwise again, and the sample 17 in the second test chamber 4 on the fourth outer plane enters the test position and is tested again. The sample 17 is tested again. The continuous injection and continuous testing are carried out in the above manner, which greatly improves the work efficiency.

[0098] It is understandable that the rotation here can also be counterclockwise. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0099] In some other implementations, the rotating test cavity includes at least one outer plane (e.g., one outer plane and the others are arc surfaces; or, it can be three outer planes, the others are arc surfaces; or it can include one outer plane and the others are convex or concave surfaces, as long as it can be ensured that at least one outer plane has a second test cavity 4), and each outer plane has at least one second test cavity 4.

[0100] In this embodiment, preferably, when the first test cavity 3 and the second test cavity 4 form a sealed space, the central axis of the sealed space is perpendicular to the horizontal plane (i.e., the first test cavity 3 and the second test cavity 4 are strictly vertically positioned during the sealing test); it can be understood that when the first test cavity 3 and the second test cavity 4 form a sealed space, the central axis of the sealed space forms an acute angle greater than zero with the vertical direction upward along the horizontal plane (i.e., the first test cavity 3 and the second test cavity 4 are inclined during the sealing test, as long as it does not affect the specific test).

[0101] In this embodiment, the bottom of the rotating test chamber is provided with a receiving mechanism for receiving the sample 17.

[0102] Optionally, the receiving mechanism is a receiving box 7, the bottom of which is slidably connected to the slide rail 8. It is understood that in some other implementations, the receiving mechanism may also be other boxes, barrels, etc., and a smart car (such as an AGV) may be used for transfer. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0103] Optionally, in some other implementations, the side of the rotating test chamber is provided with an adsorption component 6 for absorbing the tested sample 17. Taking the rotating test chamber with four vertically adjacent outer planes provided in this embodiment as an example, after the sample 17 is tested, it can be rotated 90° and then sucked up by the adsorption component 6 and placed in the bearing device (which can be a receiving mechanism, other mechanisms, or other temporary positions). Alternatively, it can be rotated 90° again until the sample 17 is completely facing downwards. At this time, the sample 17 automatically slides down and falls into the receiving mechanism to complete the transfer of the sample 17. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0104] In this embodiment, optionally, the first driving mechanism is a compression cylinder 5, and the output end of the compression cylinder 5 is connected to the first test chamber 1; it is understood that in some other implementations, the first driving mechanism may also be an electric driving mechanism or a hydraulic cylinder driving mechanism, and those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0105] Example 2:

[0106] Embodiment 2 of the present invention provides a multi-station rotary testing system for sealing testing, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a sample feeding device and a multi-station rotary testing device for sealing performance testing as described in Embodiment 1 of the present invention.

[0107] The sample feeding device includes a second driving mechanism and a feeding assembly. The second driving mechanism is used to push a sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber.

[0108] Optionally, in some other implementations, the second drive mechanism is a cylinder, hydraulic cylinder, or electric drive mechanism, the output of which is used to push a sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber.

[0109] Preferably, in this embodiment, the second driving mechanism is a cylinder 14, a hydraulic cylinder, or an electric driving mechanism. The output end of the cylinder 14, hydraulic cylinder, or electric driving mechanism is connected to one end of the push rod 15. The other end of the push rod 15 is used to push a sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber under the push of the second driving mechanism.

[0110] Preferably, in this embodiment, the feeding assembly is a vertical material box 16, and the samples 17 are arranged sequentially from bottom to top. The second driving mechanism pushes one sample 17 from the vertical material box 16 into the second test chamber 4 of the rotating test chamber each time. In this embodiment, it is preferred to push the bottom sample 17 into the second test chamber 4. It is understood that in some other implementations, the second to last or other samples 17 can also be pushed into the second test chamber 4. Those skilled in the art can make the selection according to the specific working conditions, which will not be elaborated here.

[0111] Optionally, in some other implementations, the feeding assembly is a rotary feeding disk 19, which rotates along a rotary feeding disk shaft 18. The rotary feeding disk 19 has multiple through holes for accommodating samples 17. The second drive mechanism pushes the sample 17 in one through hole into the second test chamber 4 of the rotary test chamber each time. Here, the rotary feeding disk shaft 18 of the rotary feeding disk 19 is a horizontal axis that can rotate in a vertical plane. Its rotation plane is perpendicular to the pushing direction of the second drive mechanism. The rotary feeding disk 19 aligns the through hole containing one sample 17 with the second drive mechanism each time to achieve continuous sample feeding.

[0112] Optionally, in some other implementations, the feeding component is a horizontal sample tray 20, which is fixed on a sliding member (i.e., a movable slider 21, or other sliding members such as pulleys). The movable slider 21 can move horizontally with the cooperation of the third driving mechanism. Each time, the second driving mechanism pushes one sample 17 from the horizontal sample tray 20 into the second test chamber 4 of the rotating test chamber.

[0113] In this embodiment, optionally, a sealing element is arranged on the plane opposite to the second test cavity 2 on the first test cavity 1 around the opening of the first test cavity 3; the sealing element can be a sealing ring 9 or other sealing mechanism, which can be selected by those skilled in the art according to the specific working conditions, and will not be described in detail here.

[0114] Optionally, in some other implementations, a sealing element may be arranged around the opening of the second test cavity 4 on the plane opposite to the first test cavity 1 on the second test cavity 2; or the first test cavity 1 and the second test cavity 2 may be arranged simultaneously. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0115] Optionally, in this embodiment, the rotating shaft 12 of the rotating test chamber is connected to the fourth driving mechanism and rotates under the drive of the fourth driving mechanism; specifically, the fourth driving mechanism includes: a motor 10 and a coupling 11, and the motor 10 is connected to the rotating shaft 12 through the coupling 11.

[0116] Understandably, in some other implementations, the fourth drive mechanism can also be a drive mechanism that combines the motor 10 with the gear mechanism; or, the fourth drive mechanism can also be a drive mechanism that combines the motor 10 with the synchronous belt. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0117] Optionally, a support is also included, with the first test chamber 1 and the second test chamber 2 arranged directly or indirectly on the support.

[0118] Example 3:

[0119] Embodiment 3 of the present invention provides a multi-station rotary testing device for sealing performance testing, such as... Figure 5 , Figure 6 and Figure 7 As shown, it includes: a first test chamber 1 and a second test chamber 2;

[0120] The first test chamber 1 has a first test chamber 3. The second test chamber 2 is a rotating test chamber with a vertical axis 12. At least one second test chamber 4 is opened on the rotating test chamber. The first test chamber 3 is used to cooperate with the second test chamber 4 under the drive of the first drive mechanism to form a sealed space for accommodating the sample 17.

[0121] In this embodiment, the second test cavity 4 is opened on the outer plane of the rotating test cavity, and at least one second test cavity 4 is opened on each outer plane.

[0122] In one alternative implementation, a second test chamber 4 is formed on each outer plane, so that a sample 17 is inserted at a time. After the sample is inserted, the test chamber is rotated, and the second test chamber 4 cooperates with the first test chamber 3 to seal the sample 17 and perform a sealing test on the sample 17. After the test is completed, the first test chamber 3 and the second test chamber 4 are separated, and the test chamber is rotated again to test the next sample 17.

[0123] In another alternative implementation, each outer plane has multiple (e.g., three, four, five or more) second test chambers 4, and the number of second test chambers 4 on each outer plane is the same (e.g., the number of second test chambers 4 on each outer plane is 5, and the spacing between adjacent second test chambers 4 on each outer plane is the same). The first test chamber 1 has the same number of first test chambers 3 as the number of second test chambers 4 on any outer plane, and they are matched one-to-one (that is, no matter which outer plane is rotated to a position opposite to the first test chamber 1, the same number of first test chambers 3 are matched with the second test chambers 4 to realize the testing of multiple samples 17).

[0124] Understandably, in some other implementations, multiple first test chambers 1 may also be included. The number of first test chambers 3 and second test chambers 4 on each side of each first test chamber 1 are the same and they are matched one by one. That is, each first test chamber 3 is configured with a first test chamber 1 so that no matter which outer plane is rotated to be opposite to the position of the first test chamber 1, there are always the same number of first test chambers 3 and second test chambers 4 to achieve the testing of multiple samples 17.

[0125] Optionally, in some other implementations, the cross-section of the rotating test chamber perpendicular to the rotating shaft 12 is a regular N-gon. The rotating test chamber includes an outer plane of N, where N is a positive integer greater than or equal to 3. For example, when N is 3, one outer plane can be selected for feeding, one for testing, and one for discharging. It is understood that when the number of N meets the requirements, multiple feeding positions, multiple testing positions, and multiple discharging positions can be selected. Those skilled in the art can make selections according to specific working conditions, which will not be elaborated here.

[0126] Preferably, the rotating test chamber includes four vertically adjacent outer planes, and at least one second test chamber 4 is provided on each outer plane; it can be understood that the cross section of the rotating test chamber perpendicular to the rotation axis 12 can be a square (obtained by rounding the four corners of a square). In this embodiment, only one second test chamber 4 is provided on each outer plane, and the second test chambers 4 on each outer plane are symmetrically arranged along the rotation axis 12.

[0127] Specifically, the rotating test chamber includes a first outer plane, a second outer plane, a third outer plane, and a fourth outer plane that are sequentially adjacent to each other. Each of the first outer plane, the second outer plane, the third outer plane, and the fourth outer plane has a second test chamber 4. After the sample is injected into the second test chamber 4 on the first outer plane, the rotating test chamber rotates 90° clockwise. At this time, the second test chamber 4 cooperates with the first test chamber 3 to seal the first test chamber 3 (at this time, the central axis of the sealed chamber is perpendicular to the horizontal plane). Then, a vacuum test is performed. The second test chamber 4 on the fourth outer plane is injected with the sample again and waits. After the sample 17 in the second test chamber 4 on the first outer plane is tested, the first test chamber 3 and the second test chamber 4 are separated. At this time, the rotating test chamber rotates 90° clockwise again, and the sample 17 in the second test chamber 4 on the fourth outer plane enters the test position and is tested again. The sample injection and continuous testing are performed in the above manner, which greatly improves the work efficiency.

[0128] It is understandable that the rotation here can also be counterclockwise. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0129] Understandably, in some other implementations, the cross section of the rotating test cavity perpendicular to the rotation axis 12 is a quasi-hexagon (obtained by rounding the corners of the regular hexagon). The first test cavity 1 can be arranged at the corresponding positions of three consecutive outer planes to achieve simultaneous or synchronous testing of the sample 17 on the three outer planes. Of course, similarly, multiple second test cavities 4 can be arranged on each outer plane. Those skilled in the art can select according to the specific working conditions, which will not be elaborated here.

[0130] In some other implementations, the rotating test cavity includes at least one outer plane (e.g., one outer plane and the others are arc surfaces; or, it can be three outer planes, the others are arc surfaces; or it can include one outer plane and the others are convex or concave surfaces, as long as it can be ensured that at least one outer plane has a second test cavity 4), and each outer plane has at least one second test cavity 4.

[0131] In this embodiment, preferably, when the first test cavity 3 and the second test cavity 4 form a sealed space, the central axis of the sealed space is perpendicular to the horizontal plane (i.e., the first test cavity 3 and the second test cavity 4 are strictly vertically positioned during the sealing test); it can be understood that when the first test cavity 3 and the second test cavity 4 form a sealed space, the central axis of the sealed space forms an acute angle greater than zero with the vertical direction upward along the horizontal plane (i.e., the first test cavity 3 and the second test cavity 4 are inclined during the sealing test, as long as it does not affect the specific test).

[0132] In this embodiment, a receiving mechanism for receiving the sample 17 is also provided; optionally, the receiving mechanism is a receiving box 7, the bottom of which is slidably connected to the slide rail 8; it is understood that in some other implementations, the receiving mechanism can also be other boxes, barrels, etc., and an intelligent vehicle (e.g., AGV) can be used for transportation. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0133] The side of the rotating test chamber is provided with an adsorption component 6 for absorbing the tested sample 17. Taking the rotating test chamber with four vertically adjacent outer planes provided in this embodiment as an example, after the sample 17 is tested, it can be rotated 90° and then the adsorption component 6 can absorb it and place the sample 17 in the carrier device; or it can be rotated 90° again and then the adsorption component 6 can absorb it and place the sample 17 in the carrier device. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0134] In this embodiment, optionally, the first driving mechanism is a compressed air cylinder 5, an electric cylinder, or an electric drive mechanism, and the output end of the first driving mechanism is connected to the first test chamber 1.

[0135] Example 4:

[0136] Embodiment 4 of the present invention provides a multi-station rotary testing system for sealing testing, such as... Figure 5 , Figure 6 and Figure 7 As shown, it includes a sample feeding device and a multi-station rotary testing device for sealing performance testing as described in Embodiment 3 of the present invention;

[0137] The sample feeding device includes a second driving mechanism and a feeding assembly. The second driving mechanism is used to push a sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber.

[0138] Optionally, in some other implementations, the second drive mechanism is a cylinder, hydraulic cylinder, or electric drive mechanism, the output of which is used to push a sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber.

[0139] Preferably, in this embodiment, the second driving mechanism is a cylinder, a hydraulic cylinder, or an electric driving mechanism. The output end of the cylinder, hydraulic cylinder, or electric driving mechanism is connected to one end of the push rod 15, and the other end of the push rod 15 is used to push a sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber under the push of the second driving mechanism.

[0140] Preferably, in this embodiment, the feeding assembly is a vertical material box 16, and the samples 17 are arranged sequentially from bottom to top. The second driving mechanism pushes one sample 17 from the vertical material box 16 into the second test chamber 4 of the rotating test chamber each time. In this embodiment, it is preferred to push the bottom sample 17 into the second test chamber 4. It is understood that in some other implementations, the second to last or other samples 17 can also be pushed into the second test chamber 4. Those skilled in the art can make the selection according to the specific working conditions, which will not be elaborated here.

[0141] Optionally, in some other implementations, the feeding assembly is a rotary feeding disk 19, which has multiple through holes for accommodating samples 17. The second drive mechanism pushes the sample 17 in one through hole into the second test chamber 4 of the rotary test chamber each time. Here, the rotary feeding disk 19 has a horizontal axis 18 that can rotate in a vertical plane. Its rotation plane is perpendicular to the pushing direction of the second drive mechanism. The rotary feeding disk aligns the through hole containing one sample 17 with the second drive mechanism each time to achieve continuous sample feeding.

[0142] Optionally, in some other implementations, the feeding assembly is a horizontal sample tray, which is fixed on a sliding member. The sliding member can move horizontally with the cooperation of a third drive mechanism. Each time, the second drive mechanism pushes one sample 17 from the horizontal sample tray into the second test chamber 4 of the rotating test chamber.

[0143] In this embodiment, optionally, a sealing element is arranged on the plane opposite to the second test cavity 2 on the first test cavity 1 around the opening of the first test cavity 3; the sealing element can be a sealing ring 9 or other sealing mechanism, which can be selected by those skilled in the art according to the specific working conditions, and will not be described in detail here.

[0144] Optionally, in some other implementations, a sealing element may be arranged around the opening of the second test cavity 4 on the plane opposite to the first test cavity 1 on the second test cavity 2; or the first test cavity 1 and the second test cavity 2 may be arranged simultaneously. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0145] Optionally, in this embodiment, the rotating shaft 12 of the rotating test chamber is connected to the fourth driving mechanism and rotates under the drive of the fourth driving mechanism; specifically, the fourth driving mechanism includes: a motor 10 and a coupling 11, and the motor 10 is connected to the rotating shaft 12 through the coupling 11.

[0146] Understandably, in some other implementations, the fourth drive mechanism can also be a drive mechanism that combines the motor 10 with the gear mechanism; or, the fourth drive mechanism can also be a drive mechanism that combines the motor 10 with the synchronous belt. Those skilled in the art can choose according to the specific working conditions, which will not be elaborated here.

[0147] Optionally, a support is also included, with the first test chamber 1 and the second test chamber 2 arranged directly or indirectly on the support.

[0151] The second drive mechanism pushes one of the sample 17 from the feeding assembly into the second test chamber 4 of the rotating test chamber;

[0152] The test chamber is rotated so that the second test chamber 4, which carries the test sample 17, cooperates with the first test chamber 3 to seal the test sample 17 in the sealed space.

[0153] After the sealing test is completed, the test chamber is rotated, and the completed sample 17 falls into or is transferred to the receiving mechanism.

[0154] The above description is merely a preferred 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.
