Description

Technical Field

[0001] The invention belongs to the technical field of rubber sealing component production, and in particular relates to a pressure detection device for rubber sealing components. Background Art

[0002] In the production process of rubber seals, pressure testing is a key link to ensure product quality. Rubber seals are usually used in various machinery, equipment and pipelines to prevent liquid or gas leakage. Therefore, the seals must maintain their structural integrity and sealing performance when under pressure.

[0003] However, traditional rubber seal pressure detection methods often have limitations. On the one hand, most detection methods require manual loading and unloading, which is not only inefficient but also increases the labor intensity of operators.

[0004] On the other hand, traditional testing methods can usually only perform overall pressure tests on the entire seal. In the actual use of rubber seals, due to the greater pressure on the central area, local areas are more likely to be damaged when squeezed. If a point in the central area of ​​the seal fails the pressure test and becomes concave, the elasticity of the rubber material may cause the material in the nearby area to prop up the seal, making the damaged point difficult to detect in appearance, which may lead to leakage in actual use, or even more serious consequences.

[0005] For example, the Chinese patent application with publication number: CN115078113B provides a pressure detection device and a method for use in rubber seal production. Although the detection of rubber seals is achieved, it is not possible to detect a certain point of the seal, and manual loading and unloading is required, which is inefficient.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0044] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0045] Please see attached Figure 1-Figure 13 As shown, this embodiment provides a pressure detection device for a rubber seal, including a body 10, the body 10 includes a main body component 11, a mounting platform 12 is provided on the top of the main body component 11, and a push-up component 13 is provided on the bottom of the main body component 11;

[0046] The detection component 20 includes an active component 21 disposed on the mounting platform 12, a re-inspection component 22 is disposed on the top of the mounting platform 12, and a prompt component 23 is disposed in the re-inspection component 22;

[0047] The pressure-applying assembly 30 includes a driving assembly 31 disposed on the main assembly 11, and two sets of telescopic assemblies 32 are disposed on the driving assembly 31, wherein one set of the telescopic assemblies 32 is provided with a first auxiliary roller 33, and the other set of the telescopic assemblies 32 is provided with a second auxiliary roller 34, and the telescopic assemblies 32 are provided with an alarm assembly 35;

[0048] When the main assembly 11 transports the seal to the mounting platform 12, the telescopic assembly 32 tightens the seal from the inside, the driving assembly 31 drives the seal to approach the active assembly 21 for detection, and the alarm assembly 35 detects the test result;

[0049] The re-inspection component 22 is used for a second inspection of the seal, and the prompt component 23 is used for checking the test result.

[0050] It should be noted that a prompting assembly 23 is also provided inside the second auxiliary roller 34, so as to detect both the inner and outer sides of the sealing member.

[0051] In this embodiment, when the conveying part of the main component 11 delivers the seal to the mounting platform 12, the elongated part of the push-up component 13 is extended in time to ensure that the moving seal can be accurately caught, and then the push-up component 13 is lowered at a steady speed to place the seal steadily on the mounting platform 12. This process ensures the stability and safety of the seal during the detection and classification process. After the seal is placed on the mounting platform 12, the pressure component 30 begins to work. Two sets of telescopic components 32, respectively carrying the first auxiliary roller 33 and the second auxiliary roller 34, tighten the seal from the inside of the seal, and then the drive component 31 starts to drive the seal close to the active component 21 and continuously applies pressure. The drive part in the active component 21 rotates, driving the seal to rotate together, and performing a full-scale extrusion test on the seal. If the seal is deformed or damaged when subjected to this pressure, the alarm component 35 will immediately sound an alarm. After the seal is detected by the active component 21, the re-inspection component 22 will perform a secondary inspection on it. The re-inspection component 22 applies pressure to the seal again to verify the test result of the active component 21. If the re-inspection result is consistent with the previous test result, the prompt component 23 will send a corresponding prompt signal according to the test result. After the test is completed, the push-up component 13 will lift the seal again, and the pusher part of the main component 11 will push it to the unloading part, and send the seal to different directions according to the test results to achieve classification.

[0052] Next, please refer to Figure 2-Figure 3 The main body component 11 includes a chassis 111, a first bracket 112 is fixedly connected to the left side of the top surface of the chassis 111, a crawler 113 is installed in the top inner cavity of the first bracket 112, a first electric push rod 114 is fixedly connected to the rear side of the top surface of the chassis 111, a push block 115 is fixedly connected to the output end of the first electric push rod 114, a feed tray 116 is fixedly connected to the front side of the top surface of the chassis 111, a first motor 117 is fixedly connected to the bottom surface of the feed tray 116, and an output shaft of the first motor 117 extends out of the feed tray 116 and is fixedly connected to a lever 118;

[0053] The push-up assembly 13 includes two sets of second electric push rods 131 fixedly connected to the chassis 111 , the tops of the second electric push rods 131 are fixedly connected to a placement plate 132 , and a retaining ring 133 is fixedly connected to the right side of the top of the right placement plate 132 .

[0054] It should be noted that the crawler 113 is provided with convex strips to better drive the seal to move;

[0055] The push block 115 is disposed between the left and right sets of placement plates 132 .

[0056] In this embodiment, when the crawler 113 transports the seal to the mounting table 12, the two sets of second electric push rods 131 push the placement plate 132 to rise, so that the seal falls on the placement plate 132, and then the second electric push rod 131 descends, so that the seal descends at a steady speed and the seal is stably placed on the mounting table 12. The retaining ring 133 on the right side prevents the seal from slipping during the descent process, further ensuring the stability and safety of the operation. After the detection is completed, the placement plate 132 rises again to lift the seal. At this time, the first electric push rod 114 extends and pushes the push block 115 to move, and the push block 115 pushes the seal to the unloading tray 116. On the unloading tray 116, the first motor 117 drives the lever 118 to rotate, and the lever 118 pushes the seal to different directions according to the detection results to achieve classified unloading. This step not only improves the automation of the detection, but also makes the classification of seals more accurate and efficient.

[0057] Next, please refer to Figure 4-Figure 10 The active component 21 includes a roller 211 rotatably connected to the mounting platform 12, a second motor 212 is fixedly connected to the top surface of the chassis 111, and the bottom end of the roller 211 is fixedly connected to the output shaft of the second motor 212;

[0058] The re-inspection assembly 22 includes a re-inspection roller 221 rotatably connected to the mounting platform 12, a gear ring 222 is fixedly connected to the bottom outer ring of the re-inspection roller 221, a third motor 223 is fixedly connected to the top surface of the chassis 111, a gear 224 is fixedly connected to the output shaft of the third motor 223, and the outer ring of the gear 224 is combined with the outer ring of the gear ring 222;

[0059] The prompting assembly 23 includes a fixed ring 231 fixedly connected to the inner cavity of the re-inspection roller 221, an insulating strip 232 fixedly connected to the fixed ring 231, a plurality of conductive strips 233 fixedly connected to the insulating strip 232, a round convex rod 234 slidably connected to the re-inspection roller 221, one end of the round convex rod 234 extending into the inner cavity of the re-inspection roller 221 is fixedly connected to a spring sheet 235, the other end of the spring sheet 235 is fixedly connected to the fixed ring 231, one end of the round convex rod 234 extending into the inner cavity of the re-inspection roller 221 is fixedly connected to a power strip 236, a prompting light 237 fixedly connected to the top of the re-inspection roller 221, and the bottom of the prompting light 237 is electrically connected to the conductive strip 233;

[0060] The conductive strips 233 are provided in multiple groups, evenly distributed up and down, and the power strips 236 are provided in the area between adjacent conductive strips 233;

[0061] The driving assembly 31 includes a hydraulic rod 311 fixedly connected to the chassis 111, a slide plate 312 fixedly connected to the output end of the hydraulic rod 311, the bottom of the slide plate 312 is slidably connected to the chassis 111, the top of the slide plate 312 is fixedly connected to the mounting rod 313, and the mounting rod 313 is slidably connected to the middle of the mounting platform 12.

[0062] It should be noted that when inspecting seals of different widths, the round protruding rod 234 that cannot contact the seal can be retracted into the inspection roller 221 using materials such as transparent adhesive (not limited here) to avoid affecting the accuracy of the inspection;

[0063] The bottoms of the multiple groups of conductive strips 233 arranged on the outer ring of the fixed ring 231 are connected through an annular conductive ring (not shown in the figure), and the conductive ring is connected through an annular power connection device, such as a conductive slip ring, etc., which is not limited here, and is intended to enable the conductive strips 233 to be connected to the power supply while rotating.

[0064] In this embodiment, after the seal is fixed by the first auxiliary roller 33 and the second auxiliary roller 34, the hydraulic rod 311 pushes the slide plate 312 to slide along the chassis 111, and at the same time drives the mounting rod 313 and the seal to contact the roller 211, and continuously applies stable pressure to make the seal closely contact with the roller 211 and perform the test. At this time, the second motor 212 starts to drive the roller 211 to rotate. Since the seal has been fixed by the first auxiliary roller 33 and the second auxiliary roller 34, it rotates with the rotation of the roller 211, thereby receiving a full range of extrusion tests. After the seal has been initially tested by the active component 21, the seal is brought close to the re-inspection component 22, and then the third motor 223 is started to drive the gear 224 to rotate, thereby rotating the gear ring 222 and the re-inspection roller 221 meshed therewith. The re-inspection roller 221 and the hydraulic rod 311 apply slight pressure to the seal again to verify the test result of the active component 21. When the re-inspection roller 221 rotates, the round convex rod 234 will be squeezed by the seal and retracted into the re-inspection roller 221, so that the power strip 236 contacts the conductive strip 233. If a certain point of the seal is sunken due to the pressure test and fails to pass the test, the spring sheet 235 will push the round convex rod 234 into the groove, so that the power strip 236 will not contact the conductive strip 233, so that the prompt light 237 cannot be powered on and remains off. However, if the seal passes the test, the power strip 236 will contact the two adjacent groups of conductive strips 233 at a certain moment, forming a short circuit path, so that the prompt light 237 lights up and sends a green pass signal, thereby testing a certain point of the seal and the surrounding area. At the same time, the second auxiliary roller 34 will also perform the same test on the inner ring of the seal to ensure the accuracy of the test.

[0065] Next, please refer to Figure 11-13The telescopic assembly 32 includes a sliding rod 321 slidably connected to the inner cavity of the mounting rod 313, the inner cavity of the mounting rod 313 is fixedly connected to a third electric push rod 322, the output end of the third electric push rod 322 is fixedly connected to the inner cavity of the sliding rod 321, and the outer end of the sliding rod 321 is fixedly connected to an assembly block 323;

[0066] The alarm assembly 35 includes an alarm 351 fixedly connected to the mounting table 12, a warning light 352 is provided on the top of the alarm 351, a button 353 is fixedly connected to the bottom of the alarm 351, a fixing frame 354 is fixedly connected to the assembly block 323, a slide rod 355 is slidably connected in the fixing frame 354, a fourth motor 356 is fixedly connected to the left side of the fixing frame 354, a screw rod 357 is fixedly connected to the output shaft of the fourth motor 356, the top end of the screw rod 357 is threadedly connected in the slide rod 355, and the outer end of the slide rod 355 is fixedly connected to an extrusion block 358.

[0067] It should be noted that the assembly block 323 can also be connected to a power source so as to supply energy to the prompting component 23 in the second auxiliary roller 34 .

[0068] In this embodiment, when the seal is sleeved on the first auxiliary roller 33 and the second auxiliary roller 34, the third electric push rod 322 pushes the sliding rod 321 to slide in the inner cavity of the mounting rod 313, thereby driving the assembly block 323 and the two sets of auxiliary rollers to approach the inner ring of the seal until they are in close contact with the inner ring of the seal. When the seal contacts the roller 211, the fourth motor 356 is started, driving the screw rod 357 to rotate, driving the sliding rod 355 and the extrusion block 358 to slide outward, so that the extrusion block 358 fits the button 353 (the button 353 is not triggered at this time). If the seal is deformed during the pressure test, the assembly block 323 will push the extrusion block 358 to touch the button 353. At this time, the alarm 351 will sound an alarm and the warning light 352 will also light up to remind the staff that the seal has quality problems.

[0069] The working principle of the present invention is as follows: when the crawler 113 transports the seal to the mounting platform 12, the two sets of second electric push rods 131 push the placement plate 132 upward, causing the seal to fall onto the placement plate 132, and then the second electric push rod 131 descends, causing the seal to descend at a steady speed, placing the seal on the mounting platform 12, and sleeve the seal on the first auxiliary roller 33 and the second auxiliary roller 34, and then the third electric push rod 322 pushes the sliding rod 321 to slide in the inner cavity of the mounting rod 313, thereby driving the assembly block 323 and the two sets of auxiliary rollers to approach the inner ring of the seal until they are in close contact with the inner ring of the seal, and the seal After being fixed by the first auxiliary roller 33 and the second auxiliary roller 34, the hydraulic rod 311 pushes the slide plate 312 to slide along the chassis 111, and at the same time drives the mounting rod 313 and the seal to contact the roller 211, and continuously applies stable pressure to make the seal and the roller 211 in close contact and perform the test. When the seal and the roller 211 are in contact, the fourth motor 356 starts, drives the screw rod 357 to rotate, drives the slide rod 355 and the extrusion block 358 to slide outward, and makes the extrusion block 358 fit the button 353 (the button 353 is not triggered at this time). During the test, the second motor 212 starts to drive the roller 211 to rotate. Since the seal has been fixed by the first auxiliary roller 33 and the second auxiliary roller 34, it rotates with the rotation of the roller 211, thus receiving a full range of extrusion tests. If the seal is deformed during the pressure test, the assembly block 323 will push the extrusion block 358 to touch the button 353. At this time, the alarm 351 will sound an alarm and the warning light 352 will also light up to remind the staff that the seal has quality problems. If the seal passes the test of the active component 21, the seal is brought close to the re-inspection component 22, and then the third motor 223 is started to drive the gear 224 to rotate, thereby rotating the gear ring 222 and the re-inspection roller 221 meshed therewith. The re-inspection roller 221 and the hydraulic rod 311 apply a slight pressure to the seal again to verify the test results of the active component 21. When the re-inspection roller 221 rotates, the round convex rod 234 will be squeezed by the seal and put into the re-inspection roller 221, so that the power strip 236 contacts the conductive strip 233. If a certain point of the seal is sunken due to the pressure test and fails the test, the spring sheet 235 will push the round protrusion 234 into the groove, so that the power strip 236 will not contact the conductive strip 233, so that the warning light 237 cannot be powered and remains off.However, if the seal passes the test, the power strip 236 will contact the two adjacent groups of conductive strips 233 at a certain moment, forming a short circuit path, so that the prompt light 237 lights up and sends a green pass signal, thereby testing a certain point of the seal and the surrounding area. At the same time, the second auxiliary roller 34 will also perform the same test on the inner ring of the seal to ensure the accuracy of the test. After the test is completed, the seal is first released, and the placement plate 132 rises again to lift the seal. At this time, the first electric push rod 114 extends and pushes the push block 115 to move, and the push block 115 pushes the seal to the unloading tray 116. On the unloading tray 116, the first motor 117 drives the lever 118 to rotate, and the lever 118 pushes the seal to different directions according to the test results to achieve classified unloading. This step not only improves the automation of the test, but also makes the classification of seals more accurate and efficient.
