TECHNICAL FIELD

[0001] The application relates to the field of air tightness testing, in particular to a coffee pot semi-automatic air tightness testing mechanism and a testing method. BACKGROUND

[0002] The coffee pot has an opening, and since the coffee pot is a container, the air tightness of the container needs to be tested to exclude the possibility of liquid leakage of the coffee pot. In order to test the air tightness of the coffee pot, the coffee pot needs to be tested for air tightness. The conventional detection method adopts a fixed testing mechanism when detecting the coffee pot, which is not conducive to random adjustment according to products of different models and heights, and is not conducive to testing different products.

[0003] Therefore, it is necessary to provide a coffee pot semi-automatic air tightness testing mechanism and a testing method. SUMMARY

[0004] The coffee pot semi-automatic air tightness testing mechanism and the testing method provided by the application effectively solve the problem of poor compatibility of the testing mechanism for testing different products.

[0005] The technical scheme adopted by the application is: the coffee pot semi-automatic air tightness testing mechanism comprises a base, further comprises a lifting adjusting mechanism arranged on the base, a horizontal moving mechanism driven by the lifting adjusting mechanism, and a clamping testing mechanism arranged on the horizontal moving mechanism.

[0006] Further, the lifting adjusting mechanism comprises a first linear guide rail arranged vertically on the base, a lifting plate slidably arranged on the first linear guide rail, a lead screw mounting seat arranged on the base, a lead screw nut pair arranged on the lead screw mounting seat, and a hand wheel arranged at the end of the lead screw of the lead screw nut pair. The nut of the lead screw nut pair is fixedly connected with the lifting plate.

[0007] Further, the first linear guide rail is arranged on one side of the base, and the lead screw mounting seat is arranged on the other side of the base.

[0008] Further, the lifting adjusting mechanism further comprises a plurality of handle bolts, a gasket matched with the handle bolts, and a positioning plate arranged on the lead screw mounting seat. The positioning plate is provided with at least two through holes penetrating through both sides of the positioning plate along the Y-axis direction. The lifting plate is provided with screw holes matched with the handle bolts. The handle bolts are threadedly connected with the screw holes after penetrating through the gaskets and the through holes.

[0009] Further, the horizontal moving mechanism comprises a first linear air cylinder arranged horizontally on the lifting plate, and an elastic frame arranged on the output end of the first linear air cylinder. The clamping testing mechanism is arranged on the elastic frame.

[0010] Furthermore, the elastic frame includes a No. 1 plate disposed at the output end of the No. 1 linear cylinder, two linear bearings respectively disposed at both ends of the No. 1 plate, two guide posts respectively sleeved on the two linear bearings, a mounting plate connecting the ends of the two guide posts away from the No. 1 linear cylinder, two limiting heads respectively disposed at the ends of the two guide posts away from the mounting plate, and two springs respectively sleeved on the two guide posts, with the two ends of the springs abutting against the mounting plate and the linear bearings respectively.

[0011] Furthermore, the clamping test mechanism includes a second linear guide rail vertically mounted on the mounting plate, an upper arm slidably mounted on the second linear guide rail, a lower arm slidably mounted on the second linear guide rail, a lower limit mechanism mounted at the lower end of the mounting plate for supporting the lower arm, a second linear cylinder whose output end and cylinder body are respectively connected to the upper arm and the lower arm, a proximity switch mounted at the upper end of the mounting plate, a sensing plate mounted at the upper end of the upper wall for cooperating with the proximity switch, and a plug mounted at the lower end of the upper arm, wherein the plug is provided with an air hole.

[0012] Furthermore, the clamping test mechanism also includes a positioning post located at the upper end of the lower arm.

[0013] Furthermore, a visual inspection mechanism is also provided on one side of the base, which is used to detect whether the product to be inspected is in place.

[0014] The test method uses the aforementioned semi-automatic airtightness testing mechanism for coffee pots. The lifting mechanism is manually adjusted so that the horizontal moving mechanism moves to a predetermined height. Then, the horizontal moving mechanism drives the clamping testing mechanism to move to a predetermined horizontal position. Subsequently, the clamping testing mechanism clamps the product to achieve airtightness testing.

[0015] Beneficial effects of the invention: 1. The structural design and specific implementation of the lifting and adjusting mechanism can effectively achieve stable lifting and lowering of the horizontal moving mechanism, thereby facilitating the synchronous stable lifting and lowering of the clamping and testing mechanism. Furthermore, the lifting and adjusting mechanism is manually adjustable, making the entire mechanism of this application a semi-automatic mechanism, saving costs and easily adapting to coffee pots of different heights.

[0016] 2. The lifting adjustment mechanism is equipped with a handle bolt, a washer, and a positioning plate. The handle bolt and the washer work together to press the washer onto the positioning plate after the handle bolt is turned on the lifting plate, thereby fixing the lifting plate and preventing it from sliding down due to gravity, which would affect the testing process.

[0017] 3. The horizontal moving mechanism is equipped with an elastic frame, which can buffer the clamping test mechanism after it has moved into place through the elasticity of the frame.

[0018] 4. The clamping test mechanism is designed so that the upper and lower arms can slide along the No. 2 linear guide rail by driving the No. 2 linear cylinder, which can ensure the smooth movement of the upper and lower arms. Attached Figure Description

Visual inspection mechanism. Detailed Implementation

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the first embodiment provided in this application is a semi-automatic airtightness testing mechanism for a coffee pot, including a base 1, a lifting adjustment mechanism 2 disposed on the base 1, a horizontal moving mechanism 3 driven by the lifting adjustment mechanism 2, and a clamping testing mechanism 4 disposed on the horizontal moving mechanism 3. This application uses a PLC control system electrically connected to the horizontal moving mechanism 3 and the clamping testing mechanism 4.

[0026] In actual use, the product to be tested is first moved to the predetermined testing position. Then, the lifting adjustment mechanism 2 drives the horizontal moving mechanism 3 to rise and fall to the predetermined height. Then, the horizontal moving mechanism 3 drives the clamping testing mechanism 4 to move to the predetermined horizontal position. Then, the product to be tested is placed in the clamping testing mechanism 4 for air tightness testing.

[0027] In the above design, the lifting adjustment mechanism 2 and the horizontal moving mechanism 3 can work together to achieve dual-axis movement of the clamping test mechanism 4, thereby ensuring that the clamping test mechanism 4 can be moved quickly and stably to the predetermined testing position to test the product to be tested.

[0028] Specifically: such as Figure 2 As shown, the lifting adjustment mechanism 2 includes a first linear guide rail 21 vertically mounted on the base 1, a lifting plate 22 slidably mounted on the first linear guide rail 21, a lead screw mounting seat 23 mounted on the base 1, a lead screw nut assembly 24 mounted on the lead screw mounting seat 23, and a handwheel 25 mounted on the end of the lead screw of the lead screw nut assembly 24. The nut of the lead screw nut assembly 24 is fixedly connected to the lifting plate 22. The horizontal moving mechanism 3 is mounted on the lifting plate 22.

[0029] In actual use, when it is necessary to drive the horizontal moving mechanism 3 to rise or fall, the screw of the screw nut pair 24 is driven to rotate by turning the handwheel 25. The rotation of the screw drives the nut to move along the screw axis. The nut drives the lifting plate 22 to rise or fall along the first linear guide rail 21. The rise or fall of the lifting plate 22 drives the horizontal moving mechanism 3 to rise or fall.

[0030] In the above design, the structural design and specific implementation of the lifting adjustment mechanism 2 can effectively achieve stable lifting of the horizontal moving mechanism 3, thereby facilitating the synchronous and stable lifting of the clamping test mechanism 4. Furthermore, the lifting adjustment mechanism 2 is manually adjustable, making the entire mechanism of this application a semi-automatic mechanism, saving costs and making it suitable for coffee pots of relatively low height.

[0031] Specifically: such as Figure 2 As shown, the first linear guide rail 21 is disposed on one side of the base 1, and the lead screw mounting seat 23 is disposed on the other side of the base 1.

[0032] In the above design, the first linear guide rail 21 and the lead screw mounting seat 23 are respectively installed on both sides of the base 1, so that the lifting plate 22 and the lead screw nut pair 24 are respectively located on both sides of the base 1. The lead screw nut pair 24 and the lifting plate 22 are connected by setting through holes 201 on the base 1, which facilitates the installation of the lead screw nut pair 24 and the lifting plate 22.

[0033] Specifically: such as Figure 2As shown, the lifting adjustment mechanism 2 also includes several handle bolts 26, washers 27 that cooperate with the handle bolts 26, and a positioning plate 28 set on the lead screw mounting seat 23. The positioning plate 28 is provided with at least two through holes 201 that penetrate through both sides of the positioning plate 28 along the Y-axis direction. The lifting plate 22 is provided with screw holes that cooperate with the handle bolts 26. The handle bolts 26 pass through the washers 27 and the through holes 201 and are threadedly connected to the screw holes.

[0034] In actual use, when it is necessary to raise or lower the lifting plate 22, first rotate the handle bolt 26 so that the handle bolt 26 is not fixed to the lifting plate 22. After the lifting plate 22 is raised or lowered to the predetermined height, tighten the handle bolt 26 so that the handle bolt 26 tightens the pressure washer 27 onto the positioning plate 28, thereby fixing the lifting plate 22.

[0035] In the above design, the structural design and specific implementation of the lifting adjustment mechanism 2 facilitate the fixing of the lifting plate 22 after it is adjusted to the correct position, ensuring that the height of the clamping test mechanism 4 remains constant during the test.

[0036] Specifically: such as Figure 3 As shown, the horizontal moving mechanism 3 includes a first linear cylinder 31 horizontally arranged on the lifting plate 22, an elastic frame 32 arranged at the output end of the first linear cylinder 31, and the clamping test mechanism 4 is arranged on the elastic frame 32.

[0037] In actual use, the elastic frame 32 is driven to move horizontally by the linear cylinder 31, so that the elastic frame 32 drives the clamping test mechanism 4 to move to the predetermined horizontal position.

[0038] In the above design, the structural design and specific implementation of the horizontal moving mechanism 3 facilitate the horizontal movement of the clamping test mechanism 4, and utilize the elastic frame 32 to provide elastic buffering for the clamping test mechanism 4.

[0039] Specifically: such as Figure 3 As shown, the elastic frame 32 includes a first plate 321 disposed at the output end of the first linear cylinder 31, two linear bearings 322 respectively disposed at both ends of the first plate 321, two guide posts 323 respectively sleeved on the two linear bearings 322, a mounting plate 324 connecting the two guide posts 323 away from the first linear cylinder 31, two limiting heads 325 respectively disposed at the two guide posts 323 away from the mounting plate 324, and two springs 326 respectively sleeved on the two guide posts 323. The two ends of the springs 326 abut against the mounting plate 324 and the linear bearings 322 respectively. The clamping test mechanism 4 is disposed on the mounting plate 324.

[0040] In actual use, the first plate 321 is driven to move horizontally by the first linear cylinder 31. The movement of the first plate 321 drives the linear bearing 322, the guide post 323 and the mounting plate 324 to move, thereby realizing the movement of the clamping test mechanism 4 located on the mounting plate 324. When the mounting plate 324 moves into place, the clamping test mechanism 4 is restricted by the external mechanism, which causes the spring 326 to be compressed and the guide post 323 to move relative to the linear bearing 322 toward the first cylinder.

[0041] In the above design, the structural design and specific implementation of the elastic frame 32 facilitate the buffering of the clamping test mechanism 4 after it has been moved into place.

[0042] Specifically: such as Figure 4 As shown, the clamping test mechanism 4 includes a second plate 410 vertically mounted on the mounting plate 324, a second linear guide rail 401 mounted on the second plate 410, an upper arm 402 slidably mounted on the second linear guide rail 401, a lower arm 403 slidably mounted on the second linear guide rail 401, a lower limit mechanism 404 mounted at the lower end of the second plate 410 for supporting the lower arm 403, a second linear cylinder 405 whose output end and cylinder body are respectively connected to the upper arm 402 and the lower arm 403, a first proximity switch 406 and a second proximity switch 412 mounted at the upper end of the second plate 410, a first sensing plate 407 and a second sensing plate 411 mounted at the upper end of the upper arm for cooperating with the first proximity switch 406 and the second proximity switch 412 respectively, and a plug 408 mounted at the lower end of the upper arm 402, wherein the plug 408 is provided with an air hole.

[0043] In actual use, the vent of the plug 408 is connected to an external airtightness tester. Linear cylinder 405 first drives the upper arm 402 and lower arm 403 to move in opposite directions. When proximity switch 406 senses sensor 407, cylinder 405 stops driving, completing the opening of the upper arm 402 and lower arm 403. The coffee pot to be tested is then placed on the lower arm 403. Subsequently, linear cylinder 405 drives the upper arm 402 and lower arm 403 to close. When proximity switch 406 senses sensor 411, cylinder 405 stops driving the upper arm 402 and lower arm 403 to close. After closing, plug 408 extends into the opening of the coffee pot and seals it. The air pressure inside the coffee pot is tested by venting through the vent using an external airtightness tester. The air pressure change per unit time is compared to determine whether the coffee pot's airtightness is up to standard.

[0044] In the above design, the structural design and specific implementation of the clamping test mechanism 4 facilitate the airtightness test after clamping the coffee pot, ensuring the stability of the coffee pot during the test.

[0045] Specifically: such as Figure 4 As shown, the clamping test mechanism 4 also includes a positioning post 409 disposed on the upper end of the lower arm 403.

[0046] In actual use, the positioning pin 409 is used to position the positioning hole at the bottom of the coffee pot.

[0047] In the above design, by setting the positioning column 409, the clamping test mechanism 4 can quickly position the coffee pot during the test.

[0048] Specifically: such as Figure 1 As shown, a visual inspection mechanism 5 is also provided on one side of the base 1. The visual inspection mechanism 5 is used to detect whether the product to be inspected is in place.

[0049] In actual use, the visual inspection mechanism 5 checks whether the coffee pot to be inspected is in place.

[0050] In the above design, the visual inspection mechanism 5 facilitates the automatic detection of whether the coffee pot to be inspected is in place.

[0051] The second embodiment provided in this application is a testing method. It adopts the semi-automatic airtightness testing mechanism for coffee pots described in this application. The lifting adjustment mechanism 2 is manually adjusted so that the horizontal moving mechanism 3 moves to a predetermined height. Then, the horizontal moving mechanism 3 drives the clamping testing mechanism 4 to move to a predetermined horizontal position. Subsequently, the clamping testing mechanism 4 clamps the product to achieve airtightness testing.

[0052] In the above design, the position of the clamping test mechanism 4 can be adjusted by the lifting adjustment mechanism 2 and the horizontal moving mechanism 3, which facilitates the testing of different models of coffee pots.

[0053] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
